Background. In this retrospective study, we aimed to compare the results of two surgical techniques, conventional and transverse mini-incision. Materials and Methods. 95 patients were operated between 2011 and 2012 in Bitlis State Hospital. 50 patients were operated with conventional technique and 45 of them were operated with minimal transverse incision. Postoperative complications, incision site problems, and the time of starting to use their hands in daily activities were noted. Results. 95 patients were included in the study. The mean age was 48. 87 of them were female and 8 were male. There was no problem of incision site in both of the two surgical techniques. Only in one patient, anesthesia developed in minimal incision technique. The time of starting to use their hands in daily activities was 22,2 days and 17 days in conventional and minimal incision technique, respectively. Conclusion. Two surgical techniques did not show superiority to each other in terms of postoperative complications and incision site problems except the time of starting to use their hands in daily activities.

This article reports the use of a customized surgical guide for simple and precise C-tube plate placement with minimized incision. Patients who were planning to have orthodontic miniplate treatment because of narrow interradicular space were recruited for this study. A combined silicone and stainless steel wire surgical guide for the C-tube was fabricated on the cast model. The taller wire of the positioning guide is used to accurately start the incision. The incision guide-wire position is verified by placing the miniplate on the coronal horizontal wire to confirm that the incision will coordinate with the screw holes. Because the miniplate is firmly held in place, there is no risk of the miniplate anchoring screws (diameter, 1.5 mm; length, 4 mm) sliding on the bone surface during placement with a manual hand driver. The surgical guide was placed on the clinical site, and it allowed precise placement of the miniplate with minimum incision and preventing from slippage or path-of-insertion angulation errors that might interfere with accurate placement. Customized surgical guide enables precise planning for miniplate positions in anatomically complex sites.

Laparoscopy was a progressive step to advancing surgical procedures as it minimised the scars left on the body after surgery, compared to traditional open surgery. Many years later, single-incision laparoscopic surgery (SILS) was created where, instead of having multiple incisions, only one incision is made or multiple small incisions in one location. SILS, or laparoendoscopic single-site surgery (LESS), may produce lesser scars but drawbacks for the surgeons are still present. This paper aims to present related literature of the recent technological developments in laparoscopic tools and procedure particularly in the vision system, handheld instruments. Tech advances in LESS will also be shown. Furthermore, this review intends to give an update on what has been going on in the surgical robot market and state which companies are interested and are developing robotic systems for commercial use to challenge Intuitive Surgical's da Vinci Surgical System that currently dominates the market.

Children who have had surgery involving the placement of an implant frequently undergo a subsequent surgery for hardware removal. The cosmesis of surgical scars following initial and subsequent surgeries is unpredictable. Scar incision (subsequent surgical incision through the initial scar) or excision (around the initial scar) is selected on the basis of the quality of the initial scar. The outcomes following these techniques have not been determined. This prospective, consecutive case series was designed to compare outcomes following surgical scar incision versus excision at the time of implant removal in children with cerebral palsy. Photographs of the scars were made preoperatively and at 6 and 12 months following implant removal and were graded for scar quality utilizing the modified Stony Brook Scar Evaluation Scale (SBSES). Parental assessment of scar appearance was performed at the same time points utilizing a visual analog cosmetic scale (VACS). The scars that were selected for incision had significantly worse SBSES scores at 6 and 12 months following the second surgery compared with preoperative values. However, parents' VACS scores of the incised scars, although worse at 6 months, were comparable with preoperative scores at 12 months. Scars that were selected for excision had significantly worse SBSES scores at 6 months but scores that were comparable with preoperative values at 12 months. VACS scores for the excised scars were comparable at the 3 time points. Surgical incisions that initially healed with good scar quality generally healed well (from the parents' perspective) following subsequent incision through the previous scar. Surgical incisions that initially healed with poor scar quality did not heal better following excision of the previous scar. In such situations, surgical excision of the existing scar should occur in conjunction with additional adjuvant therapies to improve cosmesis. Therapeutic Level II.

The mid-to-lower segment of tibiofibular fractures (MLTFs) is commonly encountered in clinical practice, which is conventionally treated by the double-incision surgical approach. However, the double-incision approach frequently makes the closure of the wound extremely difficult and sometimes results in necrosis of skin around fractured sites. In the present study, our experience of using a single-incision surgical approach for treating MLTF was exhibited. From February 2005 to December 2013, the clinical outcomes of 212 patients with MLTFs who underwent either double-incision approach or single-incision approach were retrospectively evaluated and compared. Both groups were similar with respect to injury mechanism and all patients were followed up with the efficacies of treatment evaluated by Johner-Wruth criteria. The results demonstrated that the effective rate and the rate of excellent and good efficacy in the single-incision group were significantly higher than those in the double-incision group (P<0.05). In addition, the rates of skin wound healing and bone union after surgery in the single-incision group were significantly higher than those in the double-incision group (P<0.05). These findings indicate that the single-incision surgical approach, which holds the advantages of being milder in trauma, fewer in complications and better in function restoration, might be used as an alternative method for treating MLTFs.

In a previous study, we showed that a deep thoracic incision induces the segmental upregulation of interleukin-1β (IL-1β) in the spinal cord. However, whether the cytokines tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) are also activated in response to surgical incision remains to be determined. The present study aimed to investigate the expression pattern of TNF-α and IL-6 in the spinal cord following a deep thoracic incision. After surgical incision, the mRNA levels of TNF-α and IL-6 in the thoracic spinal cord were transiently upregulated as determined by real-time polymerase chain reaction (PCR) assay. However, the activation of IL-6 was detected at 1 h postoperatively, which was earlier compared to that of TNF-α, observed at 6 h postoperatively. The activated TNF-α was mainly localized in the neurons, but not in microglia or astrocytes as determined by immunohistochemistry and confocal microscopy. However, the increased IL-6-immunoreactivity was mainly expressed in blood vessels. The differential upregulation of TNF-α and IL-6 induced by incision suggests that the proinflammatory cytokines may play different roles in the development of surgical pain.

Four level-three Japanese obstetric centres. Thirty-four women with prior caesarean section and placenta praevia that widely covers the anterior uterine wall, in whom placenta accreta cannot be ruled out. A transverse fundal incision was performed at the time of caesarean section and manual placental removal was attempted under direct observation. Operative fluid loss. The total volume of fluid lost during our operative procedure compares favourably with the volume lost during our routine transverse lower-segment caesarean sections performed in patients without placenta praevia or accreta. The average fluid loss was 1370 g. No patients required transfer to intensive care, and there were no cases of fetal anaemia. This procedure has the potential to reduce the heavy bleeding that arises from caesarean deliveries in women with placenta praevia and placenta accreta. © 2013 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2013 RCOG.

Hand-assisted laparoscopic donor nephrectomy is performed in many centers for donor nephrectomy. A midline incision for hand-assisted port placement is generally used but produces an unsightly scar. In this study, patients who had hand-assisted laparoscopic donor nephrectomy with low transverse incision were compared with those who received a midline incision. Our study group included patients who received hand-assisted laparoscopic donor nephrectomy from February 2012 to December 2014 at Korea University Anam Hospital. We retrospectively compared outcomes of these patients based on midline incision (45 patients) versus low transverse incision (17 patients). Risk factors, including age, sex, body mass index, creatinine level, glomerular filtration rate of allograft, side of graft kidney, number of renal arteries, duration of surgical procedure, and warm ischemic time, were compared between the midline and low transverse incision groups. When we compared the midline versus low transverse incision groups, duration of surgical procedure (P = .043), postoperative day 3 glomerular filtration rate (P = .017), and postoperative day 3 pain score (P = .049) were significantly higher in the low transverse incision group versus the midline incision group. Postoperative day 3 results for duration of hospitalization (P = .030) and pain score (P = .021) were also significantly higher in the low transverse versus midline incision groups when we focused on patients with left nephrectomy. Hand-assisted laparoscopic donor nephrectomy with low transverse incision is more painful and necessitates a longer hospital stay and longer surgical procedure. Despite these disadvantages, hand-assisted laparoscopic donor nephrectomy with low transverse incision can offer a better cosmetic outcome with no definitive differences regarding renal function compared with a midline incision. Surgeons should consider these aspects when deciding on the best method for donor nephrectomy.

The choice of the type of abdominal incision performed in caesarean delivery is made chiefly on the basis of the individual surgeon's experience and preference. A general consensus on the most appropriate surgical technique has not yet been reached. The aim of this systematic review of the literature is to compare the two most commonly used transverse abdominal incisions for caesarean delivery, the Pfannenstiel incision and the modified Joel-Cohen incision, in terms of acute and chronic post-surgical pain and their subsequent influence in terms of quality of life. Electronic database searches formed the basis of the literature search and the following databases were searched in the time frame between January 1997 and December 2013: MEDLINE, EMBASE Sciencedirect and the Cochrane Library. Key search terms included: "acute pain", "chronic pain", "Pfannenstiel incision", "Misgav-Ladach", "Joel Cohen incision", in combination with "Caesarean Section", "abdominal incision", "numbness", "neuropathic pain" and "nerve entrapment". Data on 4771 patients who underwent caesarean section (CS) was collected with regards to the relation between surgical techniques and postoperative outcomes defined as acute or chronic pain and future pregnancy desire. The Misgav-Ladach incision was associated with a significant advantage in terms of reduction of post-surgical acute and chronic pain. It was indicated as the optimal technique in view of its characteristic of reducing lower pelvic discomfort and pain, thus improving quality of life and future fertility desire. Further studies which are not subject to important bias like pre-existing chronic pain, non-standardized analgesia administration, variable length of skin incision and previous abdominal surgery are required.

Complex abdominal wall reconstruction is beset by postoperative complications. A recent meta-analysis comparing the use of closed-incision negative-pressure therapy to standard dressings found a statistically significant reduction in surgical-site infection. The use of closed-incision negative-pressure therapy is gaining acceptance in this population; however, the economic impact of this innovative dressing remains unknown. In this study, a cost-utility analysis was performed assessing closed-incision negative-pressure therapy and standard dressings following closure of abdominal incisions in high-risk patients. Cost-utility methodology involved reviewing literature related to closed-incision negative-pressure therapy in abdominal wall surgery, obtaining utility estimates to calculate quality-adjusted life-year scores for successful surgery and surgery complicated by surgical-site infection, summing costs using Medicare Current Procedural Terminology codes, and creating a decision tree illuminating the most cost-effective dressing strategy. One-way sensitivity analysis was performed to assess the robustness of the results. The aforementioned meta-analysis comparing closed-incision negative-pressure therapy to standard dressings included a subset of five studies assessing abdominal wall surgery in 829 patients (260 closed-incision negative-pressure therapy and 569 standard dressings). Decision tree analysis revealed an estimated savings of $1546.52 and a gain of 0.0024 quality-adjusted life-year with closed-incision negative-pressure therapy compared with standard dressings; therefore, closed-incision negative-pressure therapy is a dominant treatment strategy. One-way sensitivity analysis revealed that closed-incision negative-pressure therapy is a cost-effective option when the surgical-site infection rate is greater than 16.39 percent. The use of closed-incision negative-pressure therapy is cost-saving following closure of abdominal incisions in high-risk patients.

Although cutting electrocautery can be superior to the scalpel in reducing blood loss and incisional time, several reports associated electrocautery with higher rates of wound infection, impaired healing, and worse cosmesis. We performed this systematic review and meta-analysis to compare cutting electrocautery versus scalpel for surgical incisions. We conducted a computerized literature search of five electronic databases and included all published original studies comparing cutting electrocautery and scalpel surgical incisions. Relevant data were extracted from eligible studies and pooled as odds ratios (ORs) or standardized mean difference (SMD) values in a meta-analysis model, using RevMan and Comprehensive Meta-analysis software. Forty-one studies (36 randomized trials, four observational, and one quasirandom study) were included in the pooled analysis (6422 participants). Compared with the scalpel incision, cutting electrocautery resulted in significantly less blood loss (SMD = -1.16, 95% CI [-1.60 to -0.72]), shorter incisional (SMD = -0.63, 95% CI [-0.96 to -0.29]) and operative times (SMD = -0.59, 95% CI [-1.12 to -0.05]), and lower pain scores (SMD = -0.91, 95% CI [-1.27 to -0.55]) with no significant differences in terms of wound infection rates (OR = 0.92, 95% CI [0.74-1.15]) or overall subjective scar score (SMD = -0.49, 95% CI [-1.72 to 0.75]). Surgical incision using electrocautery can be quicker with less blood loss and postoperative pain scores than the scalpel incision. No statistically significant difference was found between both techniques in terms of postoperative wound complications, hospital stay duration, and wound cosmetic characteristics. Therefore, we recommend routine use of cutting electrocautery for surgical incisions. Copyright © 2017 Elsevier Inc. All rights reserved.

To share surgical management experiences of intra-abdominal intrauterine devices (IUDs) in tertiary center. A total of 27 patients were retrospectively analyzed. This retrospective study was conducted between September 1992 and April 2013 at Department of Obstetrics and Gynecology Tepecik Research and Training Hospital, Izmir, Turkey. Demographic findings, diagnostic methods, and operative notes of patients were obtained from the patient file. Of the 27 IUDs, nine (33.3%) were in omentum, four (15%) were in Douglas pouch, one in left sacrouterine ligament, one in uterovesical space and one in fundus posterior, six (22%) in left adnexial region, one in abdominal wall, one was subdiaphragmatic, one in ligamentum latum, and one in jejunum. Almost all of the patients had TCu-380 A IUDs. Seventeen patients (63%) were managed by laparoscopy, whereas laparotomy was required in ten (37%). Adhesions were found in 23 of 27 (85%) patients with varying degrees. In four cases the incision was extended due to adhesions. A missing string was the first finding of an intra-abdominal IUD. Pelvic ultrasonography, X-ray, and hysteroscopy methods should be performed in order to detect the localization of IUD in case of a missing string. Surgical approach should be the first treatment option for intra-abdominal IUDs.

Surgical robot for single-incision laparoscopic surgery.

This paper introduces a novel surgical robot for single-incision laparoscopic surgeries. The robot system includes the cone-type remote center-of-motion (RCM) mechanism and two articulated instruments having a flexible linkage-driven elbow. The RCM mechanism, which has two revolute joints and one prismatic joint, is designed to maintain a stationary point at the apex of the cone shape. By placing the stationary point on the incision area, the mechanism allows a surgical instrument to explore the abdominal area through a small incision point. The instruments have six articulated joints, including an elbow pitch joint, which make the triangulation position for the surgery possible inside of the abdominal area. The presented elbow pitch structure is similar to the slider-crank mechanism but the connecting rod is composed of a flexible leaf spring for high payload and small looseness error. We verified the payload of the robot is more than 10 N and described preliminary experiments on peg transfer and suture motion by using the proposed surgical robot.

Analgesic effects of the COX-2 inhibitor parecoxib on surgical pain through suppression of spinal ERK signaling.

Cyclooxygenase (COX)-2 inhibitors are widely used for postoperative pain control in clinical practice. However, it is unknown whether spinal sensitization is involved in the analgesic effects of COX-2 inhibitors on surgical pain. Extracellular signal-regulated kinase (ERK) in the spinal cord is implicated in various types of pain, including surgical pain. The present study investigated the role of spinal ERK signaling in the analgesic effect of the COX-2 inhibitor parecoxib on surgical pain. Surgical pain was produced in rats by surgical incision of the hind paw. Phosphorylated (p)-ERK1/2 expression was determined by immunohistochemistry. Pain hypersensitivity was evaluated by measuring the paw withdrawal threshold using the von Frey test. The selective COX-2 inhibitor parecoxib was delivered 20 min before or 20 min after the incision by intraperitoneal injection. Pretreatment with parecoxib markedly attenuated the pain hypersensitivity induced by incision. However, post-treatment with parecoxib produced minimal analgesic effects. Parecoxib inhibited the increase in spinal p-ERK expression following surgical incision. The present study thus suggests that the COX-2 inhibitor parecoxib exerts its analgesic effect on surgical pain through the inhibition of neuronal ERK activation in the spinal cord. COX-2 inhibitor delivery prior to surgery has more potent analgesic effects, suggesting the advantage of preventive analgesia for post-operative pain control.

To determine the surgically induced astigmatism (SIA) in Straight, Frown and Inverted V shape (Chevron) incisions in manual small incision cataract surgery (SICS). A prospective cross sectional study was done on a total of 75 patients aged 40y and above with senile cataract. The patients were randomly divided into three groups (25 each). Each group received a particular type of incision (Straight, Frown or Inverted V shape incisions). Manual SICS with intraocular lens (IOL) implantation was performed. The patients were compared 4wk post operatively for uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA) and SIA. All calculations were performed using the SIA calculator version 2.1, a free software program. The study was analyzed using SPSS version 15.0 statistical analysis software. The study found that 89.5% of patients in Straight incision group, 94.2% in Frown incision group and 95.7% in Inverted V group attained BCVA post-operatively in the range of 6/6 to 6/18. Mean SIA was minimum (-0.88±0.61D×90 degrees) with Inverted V incision which was statistically significant. Inverted V (Chevron) incision gives minimal SIA.

According to the literature, incisional closure complications may range from postoperative surgical site infections, representing 17-22% of health care-associated infections, surgical wound dehiscence and formation of haematomas or seromas, and can lead to delayed or impaired incision healing. These kinds of situations are more common when wounds are closed under tension or in specific patient morbidities. Obesity, in particular, is associated with an impaired blood flow to tissues, predisposing the patient to increased risk of wound complications by various mechanisms. Incisional complications can become relevant economic burdens for health care systems because of an increase in the average length of hospital stay and readmissions, and additional medical and surgical procedures. Thus, a preventive therapy may have a critical role in the management of healing. Negative pressure wound therapy (NPWT) technology as delivered by Prevena™ Customizable™ (Kinetic Concepts Inc., San Antonio, TX) has recently been the focus of a new investigation, as a prophylactic measure to prevent complications via immediate postoperative application in high-risk, clean, closed surgical incisions. The authors present a 62-year-old class II obese female, who underwent bilateral inguinal dermolipectomy. Prophylactic NPWT as delivered by Prevena™ was performed successfully over surgical incisions. Cosmetic and therapeutic results are shown. © 2014 The Authors.

The trend of surgical robotics is to follow the evolution of laparoscopy, which is now moving towards single-incision laparoscopic surgery. The main drawback of this approach is the limited maneuverability of the surgical tools. Promising solutions to improve the surgeon's dexterity are based on bimanual robots. However, since both robot arms are completely inserted into the patient's body, issues related to possible unwanted collisions with structures adjacent to the target organ may arise. This paper presents a simulator based on patient-specific data for the positioning and workspace evaluation of bimanual surgical robots in the pre-operative planning of single-incision laparoscopic surgery. The simulator, designed for the pre-operative planning of robotic laparoscopic interventions, was tested by five expert surgeons who evaluated its main functionalities and provided an overall rating for the system. The proposed system demonstrated good performance and usability, and was designed to integrate both present and future bimanual surgical robots.

Surgical site infection (SSI) and wound dehiscence are dreaded complications following laparotomy in general surgical patients, and can potentially occur more often in various comorbid states. Negative-pressure wound therapy (NPWT) has a positive effect of on open and complicated wounds and so has been used for at-risk surgical incisions with the aim of redistributing lateral tension and holding incision edges together. The aim of the present study was to compare the rate of wound complications following laparotomy in high-risk general surgical patients with a clean incision treated with closed-incision negative-pressure therapy (ciNPT) with those receiving conventional care. A retrospective review was performed of the hospital medical records of patients who underwent laparotomy between 1 October 2010 and 31 March 2012. Records of 69 patients who received ciNPT and 112 who were managed by adherent gauze dressings were included in the final analysis. Two (2.9%) patients in the ciNPT group and 23 (20.5%) in the non-NPWT group developed a wound complication following laparotomy (P < 0.0009). The relative risk (RR) was 0.14 (0.03-0.58), suggesting that infection is less likely to occur in ciNPT-treated incisions, compared with gauze dressings. ciNPT was associated with a positive clinical outcome and was a safe and effective method of postsurgical management in our general surgery patients considered to have risk of developing wound complications following laparotomy. © 2016 The Authors.

A comparison of single-suture and double-suture incision closures in seaward-migrating juvenile Chinook salmon implanted with acoustic transmitters: implications for research in river basins containing hydropower structures

DOE Office of Scientific and Technical Information (OSTI.GOV)

Brown, Richard S.; Deters, Katherine A.; Cook, Katrina V.

Reductions in the size of acoustic transmitters implanted in migrating juvenile salmonids have resulted in the ability to make shorter incisions that may warrant using only a single suture for closure. However, it is not known if one suture will sufficiently hold the incision closed, particularly when outward pressure is placed on the surgical site such as when migrating fish experience pressure changes associated with passage at hydroelectric dams. The objective of this research was to evaluate the effectiveness of single-suture incision closures on juvenile Chinook salmon (Oncorhynchus tshawytscha). Juvenile Chinook salmon were surgically implanted with a 2012 Juvenile Salmonmore » Acoustic Telemetry System (JSATS) transmitter (0.30 g) and a passive integrated transponder tag (0.10 g) and incisions were closed with either one suture or two sutures. Mortality and tag retention were monitored and fish were examined after 7 and 14 days to evaluate tissue responses. In a separate experiment, surgically implanted fish were exposed to simulated turbine passage and then examined for expulsion of transmitters, expulsion of viscera through the incision, and mortal injury. With incisions closed using a single suture, there was no mortality or tag loss and similar or reduced tissue reaction compared to incisions closed with two sutures. Further, surgery time was significantly reduced when one suture was used, which leads to less handling and reduced stress. No tags were expelled during pressure scenarios and expulsion of viscera only occurred in two non-mortally injured fish (5%) with single sutures that were also exposed to very high pressure changes. No viscera expulsion was present in fish exposed to pressure scenarios likely representative of hydroturbine passage at many Columbia River dams (e.g. <2.7 ratio of pressure change; an acclimation pressure of 146.2 absolute kpa and a lowest exposure pressure of ~ 53.3 absolute kpa). Based on these results, we recommend the use of a single suture for surgical implantation of transmitters with incisions that are approximately 5 1/2 mm long after tag insertion.« less

A comparison of 1-port, 2-port, 3-port, and 4-port laparoscopic cholecystectomy techniques from the point of view of workflow criteria was made to both identify specific workflow components that can cause surgical disturbances and indicate good and bad practices. As a case study, laparoscopic cholecystectomies, including manual tasks and interactions within teamwork members, were video-recorded and analyzed on the basis of specially encoded workflow information. The parameters for comparison were defined as follows: surgery time, tool and hand activeness, operator's passive work, collisions, and operator interventions. It was found that 1-port cholecystectomy is the worst technique because of nonergonomic body position, technical complexity, organizational anomalies, and operational dynamism. The differences between laparoscopic techniques are closely linked to the costs of the medical procedures. Hence, knowledge about the surgical workflow can be used for both planning surgical procedures and balancing the expenses associated with surgery.

The epicanthus, a lengthways cambered skinfold around the inner canthus, is particularly common in Orientals. The purpose of this study was to evaluate the surgical outcomes for patients with epicanthus after the application of a new surgical technique. A total of 753 patients with epicanthus underwent epicanthoplasty in our hospital from October 2009 to March 2017 and were enrolled in this study. All patients were treated with upper arch flap combined with extended incision of the lower eyelid surgical method, and the effects of the surgery were assessed by photographic analysis and satisfaction surveys. After the surgery, the eyelids of patients were elongated, and their inner canthi diameter was shortened without recurrence in the epicanthus. For 3.32% of the patients, there was a nonuniform edge thickness of the lower eyelid incision; for 8.23% of the patients, there was a slightly lighter skin color in the rest of quondam arch flap. Six months after the surgery, the incision scar was not obvious for all patients, and most of the patients (90.31%) were satisfied with the effect of the surgery. The upper arch flap combined with extended incision of the lower eyelid surgical method, a simple and effective surgical correction method, obtained a good cosmetic result with more secluded scar and high satisfaction for patients with epiblepharon.

According to several studies from around the globe, the modified Misgav Ladach technique simplifies the surgical procedure for cesarean section, reduces operation time, costs, and complications, and optimizes obstetric and perinatal outcomes. Compare obstetric outcomes between patients operated on using traditional cesarean section technique and those operated on using modified Misgav Ladach technique. The study included 49 patients operated on using traditional cesarean section technique and 47 patients operated on using modified Misgav Ladach technique to compare the outcomes in both surgical techniques. The modified Misgav Ladach technique was associated with more benefits than those of the traditional technique: less surgical bleeding, less operation time, less analgesic total doses, less rescue analgesic doses and less need of more than one analgesic drug. The modified Misgav Ladach surgical technique was associated with better obstetric results than those of the traditional surgical technique; this concurs with the results reported by other national and international studies.

There is an ongoing debate regarding the optimal instrument for scalp incisions: the scalpel or electrocautery. The argument generally focuses on improved healing after an incision made with a knife and decreased bleeding when using electrocautery. This study compares the use of scalpel and electrocautery in making coronal incisions for patients undergoing surgical correction of craniosynostosis. The outcome metric used is wound healing within 6 months after surgery. All patients presenting to the University of North Carolina Children's Hospital with craniosynostosis between July 1, 2007 and January 1, 2010 requiring a coronal incision for surgical correction were prospectively enrolled. In all of these patients, half of the coronal incision was made with knife; the other half, with needle tip cautery. Side of the incision was specified at the time of surgery in the operative report. Patients were excluded from the study if the instrument for incision was not specified or if only 1 modality was used for the entire incision. Sixty-eight patients underwent cranial vault reconstruction, of which 58 met inclusion criteria. Of the 58 matched pairs, 55 were analyzed statistically. The 3 excluded cases were those who had midline complications. There were 17 wound complications (15%): 8 in the knife group, 6 in the cautery group, and 3 at midline (with indeterminate side for the problem). We found no statistically significant difference in wound healing between incisions made with a knife or with electrocautery.

Background Intracoelomic implantation of electronic tags has become a common method in fishery research, but rarely are fish examined by scientists after release to understand the extent that surgical incisions have healed. Walleye (Sander vitreus) are a valuable, highly exploited fishery resource in the Laurentian Great Lakes. Here, fishery capture of walleye with internal acoustic transmitters combined with a high reward program provided multiple opportunities to examine photographs and quantify the status of surgical incisions. Walleye (n = 926) from reef and river spawning populations in Lake Erie and Lake Huron were implanted with acoustic transmitters during spring spawning events from 2011 to 2016. Incisions were closed with polydioxanone monofilament using two to three interrupted sutures. Out of 276 recaptured fish, 60 incision sites were clearly visible in photographs, and these were scored by two independent readers for incision closure, inflammation, and the presence of sutures.Results While incision sites were completely closed by 61 days post-release (95% CI 44–94), sutures remained for up to 866 days. Sutures were expelled serially during a protracted period, and the probability of observing at least one suture in a recaptured fish declined below 50% after 673 days (95% CI 442–1016). Inflammation at the incision increased during the first 71 days and then declined monotonically, remaining detectable at low levels.Conclusion Our results emphasized that sutures remained in free-ranging fish past the time when they were beneficial for incision healing. Most dissolvable sutures have been designed for use in endotherms where the body temperature and internal milieu differ dramatically from the conditions experienced by fishes in temperate climates. Identification of new suture materials for fish that facilitate healing while absorbing or dissolving in a reasonable period (e.g., a few weeks to three months) in colder temperatures (e.g., <12 °C) would be beneficial to mitigate potential adverse impacts from inflammation at the incision.

The benefits of minimally invasive surgery in pediatric urology, such as reduced length of hospital stay and postoperative pain, are less predictable compared to findings in the adult literature. We evaluated the choices that adult patients make for themselves and their children regarding scar location. We surveyed the preference for scar location/size based on surgery for bladder and kidney procedures with additional questions assessing the impact of a hidden incision, length of hospital stay and pain. The survey was posted to Amazon® Mechanical Turk®. We analyzed a total of 954 completed surveys. Surgical history was reported in 660 surveys (69%) with scar bother reported in 357 (54.2%). For pelvic surgery the initial choice was a Pfannenstiel incision for 434 respondents (45.5%), laparoscopy port incisions for 392 (41.1%) and no preference for incision location for 126 (13.2%). When incisions were illustrated relative to undergarments, 718 respondents (75.3%) chose Pfannenstiel. For kidney surgery 567 respondents (59.4%) initially chose the dorsal lumbotomy incision, 170 (17.8%) chose a flank incision, 105 (11.0%) chose laparoscopy ports and 110 (11.5%) had no preference. Respondents were told that minimally invasive surgery might result in less pain/length of hospital stay and were asked to restate the incision choice. For pelvic surgery 232 of 434 respondents (53.5%) who had chosen Pfannenstiel and 282 of 394 (71.6%) who had chosen laparoscopy remained consistent (p <0.001). For kidney surgery 96 respondents (56.5%) who chose a flank incision, 322 (56.8%) who chose dorsal lumbotomy and 68 (64.2%) who chose laparoscopy remained consistent (p = 0.349). Agreement between the incision choice by respondent as a child and for a child was 82% (κ = 0.69) for pelvic surgery and 84.6% (κ = 0.75) for kidney surgery. The smallest incision is not always the patient preferred incision, particularly in childhood when pain, length of hospital stay and blood loss may be equivocal among approaches. Discussion of surgical treatment options should include scar length, location and relationship to undergarments. Copyright © 2017 American Urological Association Education and Research, Inc.

2012-11-01

Puerperal mastitis often occurs in younger primiparous women. Most cases occur between 3 and 8 weeks postpartum. If mastitis results in the formation of a breast abscess, surgical drainage or needle aspiration is most commonly performed. We report a case of an extremely large breast abscess in a primiparous 20-year-old woman, which presented 6 weeks postpartum. Surgical incision and evacuation of 2 liters of exudate were performed, and intravenous antibiotics therapy was administered. On the sixth day after incision, we secondarily closed the wound. Examination after 3 months showed symmetrical breasts with a small scar in the incision area of the right breast. A high degree of suspicion and adequate diagnostic procedures are essential to avoid delay in the treatment of mastitis and breast abscess and thereby prevent unnecessary surgical treatment.

Incisional hernia and fascial dehiscence are associated with significant postoperative morbidity. Electrosurgical devices using pulsed radiofrequency energy and a novel electrode design markedly reduce thermal injury during cutting and coagulation while maintaining equal surgical performance. In this study, we examine fascial healing dynamics in a rat model following incision with a pulsed radiofrequency energy device (PRE), a conventional electrosurgical device, and a standard "cold" scalpel. We hypothesize that incisions made with the pulsed radiofrequency energy device will result in a superior fascial healing profile compared with conventional electrosurgery. Full thickness surgical incisions were created in rat fascia using a commercially available PRE device, conventional electrosurgery, and a scalpel. Harvested fascial specimens were analyzed for burst strength testing and healing-associated histologic characteristics at d 7, 14, 21, and 42. PRE incisions were fully healed by 6 wk with normal tissue architecture. By all measures, wounds created by the PRE device were comparable to those made with the standard scalpel. Compared with PRE, conventional electrosurgery incisions exhibited a larger zone of tissue injury (68% greater in Coag mode, P < 0.0001; 46% greater in Cut mode, P < 0.001), an increased inflammatory response and a less favorable wound architecture. In the immediate postoperative period (1 wk), burst strength testing demonstrated that PRE fascial wounds were significantly stronger than those made by electrosurgery in Coag mode (318%, P = 0.001). The favorable fascial healing profile of the PRE device suggests that it is a promising new surgical technology. The early improved strength of wounds made with this device is of particular interest, as wound dehiscence is of greatest concern early in the healing process. Published by Elsevier Inc.

The management of Obstetrics and Gynaecological Emergency is directed at the preservation of life, health, sexual function and the perpetuation of fertility. Main aim of the study was to access the burden of Surgical Emergency in Obstetrics and Gynaecology and their course of management at BPKIHS. A total of 314 women presenting at the emergency admission room of Obstetrics and Gynaecology Department of BPKIHS over two years, who required surgical intervention were included in this hospital based descriptive study. Clinical assessment and routine laboratory investigations were performed in all cases. All patients who presented with shock were resuscitated and surgery was done at earliest possible time. The age of patients ranged from 15- 55 years with approximately 43% in the 25-34 years category. Ninety two percent of them were married. Among the unmarried, 64% came with problems related to unsafe abortion. About 61% of females presenting as acute surgical abdomen had ruptured ectopic pregnancy, 7.64% had twisted ovarian cyst, and 6.26% had haemoperitoneum and pyoperitoneum following vaginal hysterectomies, total abdominal hysterectomies and caesarean section. Almost half (47.8%) of the cases underwent salphingectomy. Women present with wide range of complaints and conditions in the admission room of Obstetrics and Gynecology department of BPKIHS. Skilled clinicians, immediate investigation facilities and experienced specialty Obstetrical and Gynaecological surgeons are the main backbone of the emergency case management and saving lives. Study indicates there is need of some prospective study to establish the causes of rising trend in Ectopic Pregnancies.

A 29-year-old woman (gravida 1, para 1) had an uneventful first pregnancy and a delivery by emergency caesarean section at term. The caesarean section was complicated by a massive obstetric haemorrhage of 5000 ml. After closure, an immediate re-laparotomy was indicated due to heavy vaginal bleeding. The site of bleeding was identified as an extension of the uterine incision, and was sutured. She was stabilised by transfusion of blood and blood products in the intensive therapy unit, and discharged 5 days later. The patient was re-admitted 6 weeks later with brisk, painless vaginal bleeding, passing large clots from a well-contracted uterus. Her haemoglobin decreased from 11.8 to 7.8 g/dl overnight. In view of her history, an urgent CT angiogram was performed, which revealed the presence of a pseudo-aneurysm arising from the left uterine artery. This was successfully occluded by transarterial embolisation, obviating the need for further surgical exploration. PMID:22674937

Abstract Objectives To compare the use of an electrosurgical device with traditional cold instruments (scalpel and scissors) for midline celiotomy incision. Study design Prospective randomized controlled clinical trial. Sample population: One hundred and twenty client‐owned dogs undergoing abdominal surgery. Methods Dogs were prospectively recruited and randomized to receive electroincision or cold instrument incision. For cold incision, surgeons used basic surgical instruments including scalpel and scissors. For electroincision, surgeons only used the electrosurgical device in cutting mode. Time for the approach, blood loss, and the incision length were recorded. A blinded observer assessed pain and incision redness, swelling, and discharge at 24 and 48 hours postoperative (graded 0‐3). Owner assessment of incision healing was recorded by telephone interview. Results Blood loss during surgery was significantly lower for electroincision (mean 0.7, SD 1.7 mL) than cold incision (mean 3.0, SD 4.3 mL, P < .0001) with no significant difference in incision length or time for approach. Electroincision was associated with significantly less incision redness (cold median 1, range 0‐3; electroincision median 0, range 0‐2, P = .02) and less incision discharge (cold median 0.5 range 0‐3; electroincision median 0, range 0‐1, P = .006) at 24 hours postoperative. There was no significant difference in pain scores or incision healing in dogs receiving the two techniques. No incisional hernias were reported. A surgical site infection occurred in 1 dog (cold incision). Conclusions Electroincision for a celiotomy approach in the dog reduces blood loss, and incision redness and discharge in the immediate postoperative period without affecting the occurrence of wound complications such as infection and dehiscence (including linea alba).

Surgical scars on the palmar surface of the hand may lead to functional and also aesthetic and psychological consequences. The objective of this study was to introduce a new incision technique for periarterial sympathectomy of the hand and to compare the results of the new two-step incision technique with those of a Koman incision by using an objective questionnaire. A total of 40 patients (17 men and 23 women) with intractable Raynaud's disease or syndrome underwent surgery in our hospital, conducted by a single surgeon, between January 2008 and January 2013. Patients who had undergone extended sympathectomy or vessel graft were excluded. Clinical evaluation of postoperative scars was performed in both groups one year after surgery using the patient and observer scar assessment scale (POSAS) and the Wake Forest University rating scale. The total patient score was 8.59 (range, 6-15) in the two-step incision group and 9.62 (range, 7-18) in the Koman incision group. A significant difference was found between the groups in the total PS score (P-value=0.034) but not in the total observer score. Our analysis found no significant difference in preoperative and postoperative Wake Forest University rating scale scores between the two-step and Koman incision groups. The time required for recovery prior to returning to work after surgery was shorter in the two-step incision group, with a mean of 29.48 days in the two-step incision group and 34.15 days in the Koman incision group (P=0.03). Compared to the Koman incision, the new two-step incision technique provides better aesthetic results, similar symptom improvement, and a reduction in the recovery time required before returning to work. Furthermore, this incision allows the surgeon to access a wide surgical field and a sufficient exposure of anatomical structures.

Obstetric Fistula in Burundi: a comprehensive approach to managing women with this neglected disease

PubMed Central

2013-01-01

Background In Burundi, the annual incidence of obstetric fistula is estimated to be 0.2-0.5% of all deliveries, with 1000–2000 new cases per year. Despite this relatively high incidence, national capacity for identifying and managing obstetric fistula is very limited. Thus, in July 2010, Medecins Sans Frontieres (MSF) set up a specialised Obstetric Fistula Centre in Gitega (Gitega Fistula Centre, GFC), the only permanent referral centre for obstetric fistula in Burundi. A comprehensive model of care is offered including psychosocial support, conservative and surgical management, post-operative care and follow-up. We describe this model of care, patient outcomes and the operational challenges. Methods Descriptive study using routine programme data. Results Between July 2010 and December 2011, 470 women with obstetric fistula presented for the first time at GFC, of whom 458 (98%) received treatment. Early urinary catheterization (conservative management) was successful in four out of 35 (11%) women. Of 454 (99%) women requiring surgical management, 394 (87%) were discharged with a closed fistula, of whom 301 (76%) were continent of urine and/or faeces, while 93 (24%) remained incontinent of urine and/or faeces. In 59 (13%) cases, the fistula was complex and could not be closed. Outcome status was unknown for one woman. Median duration of stay at GFC was 39 days (Interquartile range IQR, 31–51 days). The main operational challenges included: i) early case finding and recruitment for conservative management, ii) national capacity building in obstetric fistula surgical repair, and iii) assessing the psychosocial impact of this model. Conclusion In a rural African setting, it is feasible to implement a comprehensive package of fistula care using a dedicated fistula facility, and satisfactory surgical repair outcomes can be achieved. Several operational challenges are discussed. PMID:23965150

Gynecomastia is a benign enlargement of male breast, common in adolescents and adults. To treat this deformity, we have been carrying out liposuction through small cutaneous incisions placed in the axilla and on the sternum. If necessary, we performed a surgical excision of glandular tissue through a periareolar incision. From 1995, we started to perform surgical excision of glandular tissue, if necessary, through the small incisions made for liposuction, thus avoiding the periareolar scars. We describe our experience with this technique, which we believe excellent for the correction of glandular and fatty glandular gynecomastia, obtaining excellent esthetic results and minimal local scarring.

Pre-operative prophylactic antibiotics may decrease the frequency of surgical site infection after appendectomy. However, the optimal timing for administration of pre-operative prophylactic antibiotics is unknown. The purpose of this study was to evaluate the effect of timing of prophylactic antibiotics on the frequency of surgical site infection after appendectomy. Medical records were reviewed retrospectively for 577 consecutive patients who had appendectomy for acute appendicitis from 2006 to 2009. Quality assurance guidelines for timing of prophylactic antibiotics before the skin incision were changed from 0 to 30 min before the skin incision (before June 2008) to 30 to 60 min before the skin incision (after June 2008). Surgical site infection occurred in 28 patients (4.9%). There was no difference in frequency of surgical site infection with different timing of pre-operative prophylactic antibiotic (pre-operative time 0 to 30 min: 9 infections [3.6%]; 31 to 60 min: 13 infections [5.4%]; 61 to 120 min: 5 infections [7.0%]; >120 min: 1 infection [6.6%]). Multivariable analysis showed that surgical site infection was associated significantly with medical comorbidity but not perforated appendicitis. The frequency of surgical site infection was independent of timing of preoperative prophylactic antibiotics but was associated with the presence of medical comorbidity.

Background and Objective: Complications following cardiovascular surgery incision are common in mediastinitis and wound dehiscence form, a 47% mortality rate remaining. Low Level Laser Therapy (LLLT) has been employed mainly to its effectiveness analgesic and anti-inflammatory actions, aiding the tissue repair process. The aim of this study was to evaluate infrared LLLT onto surgical incision in patients submitted to cardiovascular surgery. Materials and Methods: 40 patients were divided in two groups: Placebo Group (G1) - conventional therapy + "Laser pointer" and Laser Group (G2) - conventional therapy + Infrared Laser irradiation on surgical incision. Diode Laser was employed, C.W. mode, around the surgical wound bed, on immediate Post Operative (PO), 1st PO and 3rd PO with the following parameters: wavelength (λ): 830nm, P=35mW, E=0,75J. Results: G2 didn't present any complication and 5% of patients in G1 developed incision dehiscence and infection. On 7thPO, still a large amount of G1 patients showed pain and unquestionable inflammatory signs surrounding the surgical wound, when compared to G2. Besides, hospital stay in Laser Group was 2 times shorter than in Placebo Group (p-value=0.001). Conclusion: Infrared Laser denoted to be safe and exceptionally valuable tools in preventing morbidities on post cardiovascular surgeries.

To determine the accuracy of the Lindstrom surgical nomogram for astigmatism. A prospective multicenter study. One hundred sixty eyes of 95 patients underwent astigmatic keratotomy in eight centers by nine surgeons. Inclusion criteria for the study included age of at least 18 years with 1 to 6 diopters (D) of naturally occurring corneal astigmatism and less than 1 D of lenticular astigmatism. A standardized astigmatic keratotomy surgical technique was performed on each eye. Surgical measurements were determined using the Lindstrom surgical nomogram for astigmatism. The Holladay, Cravy, Koch vector analysis method was used to determine the change in refractive cylinder results. Refractive changes also are presented without vector analysis merely using the absolute change in refractive cylinder and axis. Multiple regression analysis was used to develop a mathematical model determining the factors predictive of the change in refractive cylinder. The significant predictors for the amount of astigmatic correction achieved were, in order of decreasing importance, the following: number of incisions (R2 = 30%), incision length (R2 = 16%), age (R2 = 8%), and gender (R2 = 2%). Astigmatism is a two-dimensional measurement of both quantity and direction that is most appropriately analyzed with vector analysis. The original Lindstrom surgical nomogram for arcuate keratotomy used in this study is still quite useful although it tended to underpredict results for many patients, especially those having two incisional surgeries. Some older subjects having minimal surgery achieved greater correction than predicted by the original nomogram. The most important factors predictive of greater astigmatic keratotomy surgical effect are incision number, incision length, older age, and male gender.

Management of obstetric hemorrhage.

PubMed

Shevell, Tracy; Malone, Fergal D

2003-02-01

A reluctance to proceed with hysterectomy for obstetric hemorrhage may be a more likely cause of preventable death in obstetrics than a lack of surgical or medical skills. Every obstetric unit should have protocols available to deal with hemorrhage and, in addition, have specific guidelines for patients who object to blood transfusions for various reasons. Risk factors for hemorrhage should be identified antenatally, using all possible imaging modalities available, and utilizing multidisciplinary resources whenever possible. Novel strategies for prenatal diagnosis of abnormal placentation include advanced sonography and magnetic resonance imaging. Placement and utilization of arterial catheters for uterine artery embolization is becoming more widespread and new surgical technology such as the argon beam coagulator seems promising. When intra or postpartum hemorrhage is encountered, a familiar protocol for dealing with blood loss should be triggered. Timely hysterectomy should be performed for signs of refractory bleeding. Application of medical and surgical principles combined with recent technologic advances will help the obstetrician avoid disastrous outcomes for both mother and fetus.

Twelve consecutive patients underwent SILStoma for transverse colostomy at Osaka Medical Center for Cancer and Cardiovascular Diseases from April 2013 to March 2016. A single, intended stoma site was created with a 2.5-3.5 cm skin incision for primary access to the intra-abdominal space, and it functioned as the main port through which multi-trocars were placed. Clinical and operative factors and postoperative outcomes were evaluated. Patient demographics, including age, gender, body mass index, and surgical indications for intestinal diversion were evaluated. SILStoma was performed in nine cases without the requirement of additional ports. In the remaining three cases, 1-2 additional 5-mm ports were required for mobilization of the transverse colon and safe dissection of abdominal adhesions. No cases required conversion to open surgery. In all cases, SILStoma was completed at the initial stoma site marked preoperatively. No intraoperative or postoperative complications greater than Grade II (the Clavien-Dindo classification) were reported in the complication survey. Surgical site infection at stoma sites was observed in four cases; however, surgical interventions were not required and all infections were cured completely. In all cases, the resumption of bowel movements was observed between postoperative days 1 and 2. SILStoma for transverse loop colostomy represents a feasible surgical procedure that allows the creation of a stoma at the preoperatively marked site without any additional large skin incisions.

Although pilonidal disease has been a well-known entity for more than a century, recurrence of pilonidal disease is still not rare. The optimal surgical approach to recurrent disease is under debate. In this study, we aimed to investigate the efficacy of "incision and curettage" procedure for recurrent pilonidal disease. From May 2009 to May 2013, 42 patients (37 male/5 female) underwent surgical treatment for recurrent pilonidal disease. Incision and curettage of granulation tissue, hair and debris in the cavity were performed in all cases. Data collection included demographics, visual analogue scale (VAS) score, hospital stay, return to daily activities (lying, sitting down in comfort) and work, and complete wound healing time. Mean operating time was 16.6±4.7 (10-24) minutes. Mean pain score was 1.4±1.1 (0-5) with VAS. The mean duration of returning to daily activities such as comfortable lying down, sitting and returning to work were 1.6±0.8 (1-4) days, and 3.3±2.3 (1-15) days, and 10.2±5.4 (5-33) days, respectively. The mean wound healing time was 19.9±7.8 (7-52) days. During the three-year follow-up period, no recurrence was observed. "Incision and curettage" may be performed as first-line treatment for recurrent cases. It does not require surgical skill and can be easily applied in a short time. This simple surgical option, incision curettage provides short hospital stay and quick return to daily activities, in addition to patient comfort and satisfaction.

Obstetric surgical site infections (SSIs) are common and expensive to the health care system but remain under reported given shorter postoperative hospital stays and suboptimal post-discharge surveillance systems. SSIs, for the purpose of this paper, are defined according to the Center for Disease Control and Prevention (1999) as infection incurring within 30 days of the operative procedure (in this case, Caesarean section [CS]). Demonstrate the feasibility of real-life use of a patient driven SSIs post-discharge surveillance system consisting of an online database and mobile phone technology (surgical mobile app - how2trak) among women undergoing CS in a Canadian urban centre. Estimate the rate of SSIs and associated predisposing factors. Prospective cohort of consecutive women delivering by CS at one urban Canadian hospital. Using surgical mobile app-how2trak-predetermined demographics, comorbidities, procedure characteristics, and self-reported symptoms and signs of infection were collected and linked to patients' incision self-portraits (photos) on postpartum days 3, 7, 10, and 30. A total of 105 patients were enrolled over a 5-month period. Mean age was 31 years, 13% were diabetic, and most were at low risk of surgical complications. Forty-six percent of surgeries were emergency CSs, and 104/105 received antibiotic prophylaxis. Forty-five percent of patients (47/105) submitted at least one photo, and among those, one surgical site infection was detected by photo appearance and self-reported symptoms by postpartum day 10. The majority of patients whom uploaded photos did so multiple times and 43% of them submitted photos up to day 30. Patients with either a diagnosis of diabetes or self-reported Asian ethnicity were less likely to submit photos. Post-discharge surveillance for CS-related SSIs using surgical mobile app how2trak is feasible and deserves further study in the post-discharge setting. Copyright © 2017. Published by Elsevier Inc.

There are little primary data available on the delivery or quality of surgical treatment in rural sub-Saharan African hospitals. To initiate a quality improvement system, we characterized the existing data capture at a Ugandan Regional Referral Hospital. We examined the surgical ward admission (January 2008-December/2011) and operating theater logbooks (January 2010-July 2011) at Mbarara Regional Referral Hospital. There were 6346 admissions recorded over three years. The mean patient age was 31.4 ± 22.3 years; 29.8 % (n = 1888) of admissions were children. Leading causes of admission were general surgical problems (n = 3050, 48.1 %), trauma (n = 2041, 32.2 %), oncology (n = 718, 11.3 %) and congenital condition (n = 193, 3.0 %). Laparotomy (n = 468, 35.3 %), incision and drainage (n = 188, 14.2 %) and hernia repair (n = 90, 6.8 %) were the most common surgical procedures. Of 1325 operative patients, 994 (75 %) had an ASA I-II score. Of patients undergoing 810 procedures booked as non-elective, 583 (72 %) had an ASA "E" rating. Records of 41.3 % (n-403/975) of patients age 5 years or older undergoing non-obstetric operations were missing from the ward logbook. Missing patients were younger (25 [13,40] versus 30 [18,46] years, p = 0.002) and had higher ASA scores (ASA III-V 29.0 % versus 18.9 %, p < 0.001) than patients recorded in the logbbook; there was no diffence in gender (male 62.8 % versus 67.0 %, p = 0.20). The hospital records system measures surgical care, but improved data capture is needed to determine outcomes with sufficient accuracy to guide and record expansion of surgical capacity.

Background: Concern regarding the quality of surgical training in obstetrics and gynecology residency programs is focusing attention on competency based education. Because open surgical skills cannot necessarily be translated into laparoscopic skills and with minimally invasive surgery becoming standard in operative gynecology, the discrepancy in training between obstetrics and gynecology will widen. Training on surgical simulators with virtual reality may improve surgical skills. However, before incorporation into training programs for gynecology residents the validity of such instruments needs to first be established. We sought to prove the construct validity of a virtual reality laparoscopic simulator, the SurgicalSimTM, by showing its ability to distinguish between surgeons with different laparoscopic experience. Methods: Eleven gynecologic surgeons (experts) and 11 perinatologists (controls) completed 3 tasks on the simulator, and 10 performance parameters were compared. Results: The experts performed faster, more efficiently, and with fewer errors, proving the construct validity of the SurgicalSim. Conclusions: Laparoscopic virtual reality simulators can measure relevant surgical skills and so distinguish between subjects having different skill levels. Hence, these simulators could be integrated into gynecology resident endoscopic training and utilized for objective assessment. Second, the skills required for competency in obstetrics cannot necessarily be utilized for better performance in laparoscopic gynecology. PMID:21985726

This study evaluated the surgical performance of a 405-nm diode laser in vivo, using living rat liver tissue. Tissue was incised by irradiation with the laser at low output power ranging from 1 W (722 W/cm2) to 3 W (2165 W/cm2) on a manual control at a rate of 1 mm/s. As a control, incisions using a stainless scalpel were compared. Immediately after operation, the surface of the incisions was macroscopically observed and histopathologically evaluated by microscopy. Laser-ablated liver tissue was smooth with observable signs of remnant carbonization and easily acquired hemostasis. The thickness of the denatured layer increased in proportion to the output power; the coagulation layer did not thicken accordingly. Bleeding could not be stopped for tissues incised with the stainless scalpel. The 405-nm diode laser thus proved to be effective for ablating soft tissue with high hemostatic ability at low power.

Does UV disinfection compromise sutures? An evaluation of tissue response and suture retention in salmon surgically implanted with transmitters

DOE Office of Scientific and Technical Information (OSTI.GOV)

Walker, Ricardo W.; Brown, Richard S.; Deters, Katherine A.

Ultraviolet radiation (UVR) can be used as a tool to disinfect surgery tools used for implanting transmitters into fish. However, the use of UVR could possibly degrade monofilament suture material used to close surgical incisions. This research examined the effect of UVR on monofilament sutures to determine if they were compromised and negatively influenced tag and suture retention, incision openness, or tissue reaction. Eighty juvenile Chinook salmon Oncorhynchus tshawytscha were surgically implanted with an acoustic transmitter and a passive integrated transponder. The incision was closed with a single stitch of either a suture exposed to 20 doses of UV radiationmore » (5 minute duration per dose) or a new, sterile suture. Fish were then held for 28 d and examined under a microscope at day 7, 14, 21 and 28 for incision openness, ulceration, redness, and the presence of water mold. There was no significant difference between treatments for incision openness, redness, ulceration or the presence of water mold on any examination day. On day 28 post-surgery, there were no lost sutures; however, 2 fish lost their transmitters (one from each treatment). The results of this study do not show any differences in negative influences such as tissue response, suture retention or tag retention between a new sterile suture and a suture disinfected with UVR.« less

Small incision guarded hydroaspiration of iris lesions.

To describe the technique and results of a minimally invasive surgical technique for resection of small iris lesions. Consecutive case series of 22 patients with localised, small iris lesions that were resected using the described surgical technique that composed of multiple, small corneal incisions created to allow for internal iris resection with 23-gauge horizontal vitrectomy scissors, followed by guarded tumour aspiration through a clear plastic tubing (diameter 3.5 mm) primed with viscoelastic agent. The mean largest basal diameter was 3.0 mm (range 1.5-5.0 mm; median 3.0 mm) and mean thickness was 1.3 mm (range 0.5-2.5 mm; median 1.0 mm). Use of multiple (2-4) small corneal incisions (range 2.0-3.0 mm; mean 2.8 mm) allowed reduced postoperative morbidity (significant hyphema (0%), hypotony (0%), wound leak (0%), >2 line change in best corrected visual acuity at postoperative 1 week (4.5%) and mean corneal astigmatism of 1.0 D (range 0.14-2.99 D; median 0.8 D) at postoperative 4-12 weeks. The tumour could be resected with clear surgical margins in all neoplastic cases (benign (2), borderline (1) and malignant (16)). Local recurrence or metastases were not observed in any melanoma case over a mean follow-up of 33.0 months (range 1.0-90.0 months; median 33.5 months). Small incision guarded hydroaspiration is a minimally invasive surgical technique for resection of select small iris lesions. Use of multiple small corneal incisions avoids morbidity associated with a single large corneoscleral incision, and use of guarded aspiration may eliminate the risk of wound contamination by the malignant tumour.

Overview of surgical scar prevention and management.

PubMed

Son, Daegu; Harijan, Aram

2014-06-01

Management of incisional scar is intimately connected to stages of wound healing. The management of an elective surgery patient begins with a thorough informed consent process in which the patient is made aware of personal and clinical circumstances that cannot be modified, such as age, ethnicity, and previous history of hypertrophic scars. In scar prevention, the single most important modifiable factor is wound tension during the proliferative and remodeling phases, and this is determined by the choice of incision design. Traditional incisions most often follow relaxed skin tension lines, but no such lines exist in high surface tension areas. If such incisions are unavoidable, the patient must be informed of this ahead of time. The management of a surgical incision does not end when the sutures are removed. Surgical scar care should be continued for one year. Patient participation is paramount in obtaining the optimal outcome. Postoperative visits should screen for signs of scar hypertrophy and has a dual purpose of continued patient education and reinforcement of proper care. Early intervention is a key to control hyperplastic response. Hypertrophic scars that do not improve by 6 months are keloids and should be managed aggressively with intralesional steroid injections and alternate modalities.

Emergency obstetric hysterectomy is a procedure that potentially preserves the life and the postpartum bleeding is the direct cause of its indication, the hemorrhage postpartum happens in 1% of obstetric patients. This study was carried out to identify women with potential risk for this event and to prevent this obstetric problem. The most frequent indications for hysterectomy were identified, as well as the sociodemographic characteristic of the patients. The surgical procedure carried out was extra-fascial technique with type Richardson hysterectomy modified; the surgical pieces went to the pathology service, to obtain the histopathological diagnosis. 43 cases of obstetric hysterectomy, were analyzed; the characteristics of this group showed that bigger percentage of this event was more frequent in 31 to 35 years (39.5%), with pregnancies at term (51.1%) in third pregnancies(27.9%), nulliparas (60.4%), with first cesarean section (39.5%), without previous abortions (79.0%). The most frequent obstetric complications were uterine atony and placenta accreta. The cause for uterine atony could be interstitial edema, as well as myometrial hypertrophy, because such histopathological diagnoses were the most common. Odds ratio showed that a patient with cesarean section has 1.16 more probabilities of suffering hysterectomy than a woman with childbirth. This study describes the histological presence of interstitial edema and myometrial hypertrophy as possible causes of uterine atony in the histological study of surgical specimen. This could be related to no response of myometrial to the uterus-tonic effect of oxytocin. Obstetric uterine dysfunction has multifactorial cause. Patients with the characteristics described in this study should be considered as high risk.

Purpose To evaluate the impact of surgical factors such as incision type, number of sutures, and technique of closure on postoperative astigmatism in infants undergoing cataract extraction with or without intraocular lens implantation. Methods The IATS is a multicenter (n=12) clinical trial in which 114 infants with unilateral congenital cataracts were randomized to undergo cataract extraction with intraocular lens (IOL) placement or contact lens aphakic correction. Surgical videos were reviewed with regard to incision type and location, whether the incision was extended, the number of sutures placed, and technique of closure. Corneal astigmatism was measured using a handheld keratometer prior to surgery and at 1 year of age. Results Corneal astigmatism decreased from a mean of 1.92 D at baseline to 1.62 D at age 1 year in the CL group, but remained almost unchanged from 2.00 D to 2.09 D in the IOL group (p=0.023). There was no statistical difference between the amount of corneal astigmatism irrespective of incision type (p=0.214) and no increase in astigmatism with extension of the incision to facilitate IOL placement (p=0.849) at 1 year. The number of sutures and technique of closure did not influence the amount of astigmatism at 1 year. Conclusions At the age of one year following cataract extraction in infants, contact lens correction and the lack of IOL placement are associated with a significant decrease in postoperative corneal astigmatism compared to intraocular lens placement. No other surgical factors considered in this study had a statistically significant impact on corneal astigmatism. PMID:25266831

Post-sternotomy mediastinitis is a serious complication after cardiothoracic surgery and contribute significantly to post-operative morbidity, mortality, and healthcare costs. Negative pressure wound therapy is today’s golden standard for post-sternotomy mediastinitis treatment. A systematic literature search was conducted at PubMed until October 2012 to analyse whether vacuum-assisted closure technique prevents mediastinitis after clean surgical incisions closure. Today’s studies showed reduction of post-sternotomy mediastinitis including a beneficial socio-economic impact. Current studies, however included only high-risk patients, hence furthermore, larger randomised controlled trials are warranted to clarify the benefit for using surgical incision vacuum management systems in the general patient population undergoing sternotomy and clarify risk factor interaction.

Uterine rupture is an obstetric calamity with surgery as its management mainstay. Uterine repair without tubal ligation leaves a uterus that is more prone to repeat rupture while uterine repair with bilateral tubal ligation (BTL) or (sub)total hysterectomy predispose survivors to psychosocial problems like marital disharmony. This study aims to evaluate obstetricians' perspectives on surgical decision making in managing uterine rupture. A questionnaire-based cross-sectional study of obstetricians at the 46th annual scientific conference of Society of Gynaecology and Obstetrics of Nigeria in 2012. Data was analysed by descriptive and inferential statistics. Seventy-nine out of 110 obstetricians (71.8%) responded to the survey, of which 42 (53.2%) were consultants, 60 (75.9%) practised in government hospitals and 67 (84.8%) in urban hospitals, and all respondents managed women with uterine rupture. Previous cesarean scars and injudicious use of oxytocic are the commonest predisposing causes, and uterine rupture carries very high incidences of maternal and perinatal mortality and morbidity. Uterine repair only was commonly performed by 38 (48.1%) and uterine repair with BTL or (sub) total hysterectomy by 41 (51.9%) respondents. Surgical management is guided mainly by patients' conditions and obstetricians' surgical skills. Obstetricians' distribution in Nigeria leaves rural settings starved of specialist for obstetric emergencies. Caesarean scars are now a rising cause of ruptures. The surgical management of uterine rupture and obstetricians' surgical preferences vary and are case scenario-dependent. Equitable redistribution of obstetricians and deployment of medical doctors to secondary hospitals in rural settings will make obstetric care more readily available and may reduce the prevalence and improve the outcome of uterine rupture. Obstetrician's surgical decision-making should be guided by the prevailing case scenario and the ultimate aim should be to avert fatality and reduce morbidity.

The evolving application of single-port robotic surgery in general surgery.

2014-01-01

Advances in the field of minimally invasive surgery have grown since the original advent of conventional multiport laparoscopic surgery. The recent development of single incision laparoscopic surgery remains a relatively novel technique, and has had mixed reviews as to whether it has been associated with lower pain scores, shorter hospital stays, and higher satisfaction levels among patients undergoing procedures through cosmetically-appeasing single incisions. However, due to technical difficulties that arise from the clustering of laparoscopic instruments through a confined working space, such as loss of instrument triangulation, poor surgical exposure, and instrument clashing, uptake by surgeons without a specific interest and expertise in cutting-edge minimally invasive approaches has been limited. The parallel use of robotic surgery with single-port platforms, however, appears to counteract technical issues associated with single incision laparoscopic surgery through significant ergonomic improvements, including enhanced instrument triangulation, organ retraction, and camera localization within the surgical field. By combining the use of the robot with the single incision platform, the recognized challenges of single incision laparoscopic surgery are simplified, while maintaining potential advantages of the single-incision minimally invasive approach. This review provides a comprehensive report of the evolving application single-port robotic surgery in the field of general surgery today. © 2013 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

We performed a retrospective review of non-overweight (body mass index ≤ 25 kg/m2) patients scheduled to undergo a curative resection of locally advanced colon cancer via a transverse mini-incision (n = 62) or a longitudinal mini-incision (skin incision ≤7 cm, n = 62), with the latter group of patients randomly selected as historical controls matched with the former group according to tumor location. Extension of the transverse mini-incision wound was necessary in 3 patients (5%). Both groups were largely equivalent in terms of demographic, clinicopathological, and surgical factors and frequency of postoperative complications. Postoperative analgesic was significantly less (P = 0.04) and postoperative length of the hospital stay was significantly shorter (P < 0.01) in the transverse mini-incision group. Concerning a mini-incision approach for locally advanced colonic cancer, a transverse incision seems to be advantageous with regard to minimal invasiveness and early recovery compared with a longitudinal incision.

Therapeutic effects of various treatment options in wound healing have been one of the most controversial issues in surgical science. The present study was carried out to examine and compare the effects of Aloe vera gel, thyroid hormone cream and silver sulfadiazine cream onsutured incisions in Wistar rats. In a randomized controlled trial, thirty-six Wistar male rats, 250 to 300 g, received surgical incisions followed by topical application of Aloe vera gel, thyroid hormone cream and silver sulfadiazine 1%. To assess the efficacy of each treatment technique, a histological approach was used to evaluate the mean number of fibroblasts, macrophages, neutrophils, blood vessel sections and thickness of the regenerating epithelium and dermis on days 4, 7 and 14. Re-epithelialization and angiogenesis were significantly improved in Aloe vera gel group compared with the other treatments while thyroid hormone cream had positive effects on day 4 (P≤0.05). Topical administration of Aloe vera gel is recommended as the treatment of choice for surgical incisions. PMID:23094205

The treatment of post-surgical wound complications, such as surgical site infections and surgical wound dehiscence, generates a significant burden for patients and healthcare systems. The effectiveness of negative pressure wound therapy has been under investigation but to date no systematic review has been published in relation to its effectiveness in the prevention of surgical wound complications. To identify the effectiveness of negative pressure wound therapy in the prevention of post-surgical wound complications in adults with a closed surgical incision compared to standard surgical dressings. Male and female adults who have had negative pressure wound therapy applied to their surgical incision following a procedure in one of the following areas: trauma, cardiothoracic, orthopedic, abdominal, or vascular surgery.The intervention of interest was the use of negative pressure wound therapy directly over an incision following a surgical procedure; the comparator was standard surgical dressings.Both experimental and epidemiological study designs, including randomized controlled trials, pseudo-randomized trials, quasi-experimental studies, before and after studies, prospective and retrospective cohort studies, case control studies, and analytical cross sectional studies were sought.The primary outcome was the occurrence of post-surgical wound infection or dehiscence as measured by the following: surgical site infections - superficial and deep; surgical wound dehiscence; wound pain; wound seroma; wound hematoma. Published and unpublished studies in English from 1990 to 2013 were identified by searching a variety of electronic databases. Reference lists of all papers selected for retrieval were then searched for additional studies. Papers selected for retrieval were assessed by two independent reviewers for methodological validity prior to inclusion in the review using standardized critical appraisal instruments from the Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument. Data were extracted from the included papers using a standardized data extraction tool from the Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument. In addition to study results, the data extracted included details of the study population, setting, intervention and author's conclusion. Where appropriate, data were pooled using Comprehensive Meta-Analysis software. Meta-analyses were performed for three outcomes. In cases of heterogeneity between studies a narrative summary of results was undertaken. Eight studies were included in the review. Meta-analyses revealed a statistically significant difference in favor of the use of negative pressure wound therapy as compared to standard surgical dressings was found for surgical site infections. Conflicting results were found for wound dehiscence and seroma. Given the small number of studies, mostly retrospective comparative cohort in design, no definitive conclusions can be reached as to the effectiveness of the use of negative pressure wound therapy in the prevention of surgical wound complications. However, there was a demonstrated association between the use of negative pressure wound therapy and reduction in surgical site infection. Negative pressure wound therapy in preference to standard postoperative dressings, for example dry gauze, may be considered for closed surgical incisions in adults assessed as high-risk for surgical site infections. The focus of further research on this topic should be level one studies (randomized controlled trials) on patients identified as 'at risk' in the preoperative period.

Surgical injury in the neonatal rat alters the adult pattern of descending modulation from the rostroventral medulla.

Neonatal pain and injury can alter long-term sensory thresholds. Descending rostroventral medulla (RVM) pathways can inhibit or facilitate spinal nociceptive processing in adulthood. As these pathways undergo significant postnatal maturation, the authors evaluated long-term effects of neonatal surgical injury on RVM descending modulation. Plantar hind paw or forepaw incisions were performed in anesthetized postnatal day (P)3 Sprague-Dawley rats. Controls received anesthesia only. Hind limb mechanical and thermal withdrawal thresholds were measured to 6 weeks of age (adult). Additional groups received pre- and post-incision sciatic nerve levobupivacaine or saline. Hind paw nociceptive reflex sensitivity was quantified in anesthetized adult rats using biceps femoris electromyography, and the effect of RVM electrical stimulation (5-200 μA) measured as percentage change from baseline. In adult rats with previous neonatal incision (n = 9), all intensities of RVM stimulation decreased hind limb reflex sensitivity, in contrast to the typical bimodal pattern of facilitation and inhibition with increasing RVM stimulus intensity in controls (n = 5) (uninjured vs. neonatally incised, P < 0.001). Neonatal incision of the contralateral hind paw or forepaw also resulted in RVM inhibition of hind paw nociceptive reflexes at all stimulation intensities. Behavioral mechanical threshold (mean ± SEM, 28.1 ± 8 vs. 21.3 ± 1.2 g, P < 0.001) and thermal latency (7.1 ± 0.4 vs. 5.3 ± 0.3 s, P < 0.05) were increased in both hind paws after unilateral neonatal incision. Neonatal perioperative sciatic nerve blockade prevented injury-induced alterations in RVM descending control. Neonatal surgical injury alters the postnatal development of RVM descending control, resulting in a predominance of descending inhibition and generalized reduction in baseline reflex sensitivity. Prevention by local anesthetic blockade highlights the importance of neonatal perioperative analgesia.

Objective: To discuss the preliminary experience of single incision laparoscopic colorectal surgery. Methods: The clinical data and surgical outcomes of 104 selected patients who underwent single incision laparoscopic colorectal surgery in the 2 nd Department of General Surgery, Shengjing Hospital of China Medical University from January 2010 to September 2015 were retrospectively analyzed. There were 62 male and 42 female patients, aging from 21 to 87 years with a mean of (61±12) years. Eighty-five patients were diagnosed with malignancy while the rest 19 cases were benign diseases. All the procedures were performed by the same surgeon using the rigid laparoscopic instruments. Surgical and oncological outcomes were analyzed in 4 kinds of procedures which are over 5 cases respectively, including low anterior resection, abdominoperineal resection, radical right colon resection and radical sigmoidectomy. Results: Single incision laparoscopic colorectal surgery was performed in 104 selected patients and was successfully managed in 99 cases with a total conversion rate of 4.8%. Radical procedures for malignancy in cases with the number of patients more than 5 were performed for 74 cases. For low anterior resection, 35 cases with an average surgical time of (191±57) minutes, average estimated blood loss of (117±72) ml and average number of harvested lymph nodes of 14.6±1.1. For abdominoperineal resection, 9 cases with an average surgical time of (226±54) minutes, average estimated blood loss of (194±95) ml and average number of harvested lymph nodes of 14.1±1.5. For radical right colon resection, 16 cases with an average surgical time of (222±62) minutes, average estimated blood loss of (142±68) ml and average number of harvested lymph nodes of 15.4±2.4. For radical sigmoidectomy, 14 cases with an average surgical time of (159±32) minutes, average estimated blood loss of (94±33) ml and average number of harvested lymph nodes of 13.9±1.5. The overall intraoperative complication rate was 2.7% (2 cases) and postoperative complication rate was 8.1% (6 cases) in these 74 cases. Conclusion: Single incision laparoscopic colorectal surgery is safe and feasible with acceptable surgical outcomes and cosmetic benefits in the hands of skilled laparoscopic surgeon in well-selected patients.

To demonstrate the surgical repair of a rectovaginal fistula (RVF) using the modified Martius procedure. A step-by-step presentation of the procedure using video (Canadian Task Force classification III). RVF is abnormal epithelialized connections between the vagina and rectum. Causes of RVF include obstetric trauma, Crohn disease, pelvic irradiation, and postsurgical complications. Many surgical interventions have been developed, from the laparoscopic technique to muscle transposition and even rectal resection. However, the treatment of RVF is a great challenge to gynecologic surgeons because the incidence of RVF is low and there is no high evidence for the best surgical approach to this disease. When RVF is persistent or recurrent, the surrounding tissue is always scarred or damaged, so the interposition of a healthy and well-perfused tissue is an appropriate approach to fistula management. The modified Martius procedure using adipose tissue from the labia major places well-vascularized pedicle in the place of the RVF. Limited studies involving the procedure present favorable successful rates. Consent was obtained from the patient. The study was approved by the local ethics committee. The surgical repair of rectovaginal fistula by the modified Martius procedure is described as follows: The patient is placed in the high lithotomy position. A temporary transurethral urinary catheter is placed preoperatively to keep the operative site clean. The rectovaginal fistula is identified by a fistula probe. A 4-cm incision is made vertically over the left labium majus from the level of the mons pubis to the bottom of the labium to harvest pedicle. It is imperative to ensure adequate length on the flap before transection. Blood supply to the fat-muscle flap is provided superiorly by the external pudendal artery, posteriorly by the internal posterior and laterally by the obturator artery. The fat-muscle flap is dissected in a lateral-to-medial direction and divided in the upper section by two clamps, preserving its posterior aspect intact to maintain its blood supply. After that the fistula is circumcised with a scalpel through the vaginal wall with a margin of healthy tissue. During the process, the rectovaginal septum is opened and wide mobilized so that a multilayer closure can be performed without any tension. Then a subcutaneous tunnel is made from the labium majus to the fistula with a forcep. It is also important to make the tunnel wide enough to easily accommodate the flap. The fat-muscle flap is pulled through the tunnel gently, ensuring proper orientation without kinking the blood supply. The rectal mucosa is sutured in one layer with 3-0 Vicryl in interrupted fashion. The flap is then sutured down to the rectal wall with four single sutures in interrupted fashion. So the rectal and vaginal walls are separated with a healthy, well-vascularized pedicle. In addition, the flap fills in the dead space and enhances granulation tissue. The vaginal mucosa is then closed over the pedicle with 1-0 Vicryl in interrupted suture without tension. The labial incision is closed in layers with absorbable suture. Neither incision is drained. In this video, we describe the modified Martius procedure for the management of RVF. We present a 26-year-old woman who suffered from RVF caused by obstetric trauma. She complained of passing flatus and feces through the vagina 1 week after vaginal delivery. Clinical examination performed in the local hospital confirmed RVF 1 cm in diameter located in the lower third of the vagina. The fistula was present for about 6 months, which brought psychosocial dysfunction to the patient. She was transferred to our clinic. After examination, the anal sphincter was intact. After mechanical bowel preparation with polyethylene glycol solution, the patient was presented for surgery. The operating time was about 40 minutes. No recurrence or complications were observed at the 4-month follow-up. A protective ileostomy or colostomy was avoided. The patient reestablished intestinal continuity. The functional and cosmetic results were excellent with high patient satisfaction and greatly improved quality of life. The Martius flap is easy to harvest with minimal external disfigurement and a minimal recovery time. The modified Martius procedure is a feasible adjuvant technique for RVF with excellent postoperative outcomes. Copyright © 2018. Published by Elsevier Inc.

The study showed the treatment of frenulum breve in 24 patients. Nine of them were treated with CO2 and eight ones with Nd:YAG lasers. In seven males the classical surgical procedures were done. All patients were treated in Department of Reproduction, Institute of Gynecology and Obstetrics, Karol Marcinkowski School of Medical Sciences, Poznan, Poland between March 1995 and September 1996. All procedures were collected successful and no serious complications were observed. The all males are still under control in our department. The use of lasersurgery is the safe and efficient method in treatment of frenulum breve. Lasersurgery may be conducting as the out-patient procedure or one-day surgery because of possibility of NLA and local anesthesia. The use of CO2 seems to be the better method than Nd:YAG laser with fibertom system in treatment of frenulum breve because of shorter time of healing. There are no differences between hemostasis achieved by CO2 and Nd:YAG lasers. The incision effect is the same, when CO2 and Nd:YAG laser with fibertom system are used.

Most mortality attributable to surgical emergencies occurs in low- and middle-income countries. District hospitals, which serve as the first-level surgical facility in rural sub-Saharan Africa, are often challenged with limited surgical capacity. This study describes the presentation, management, and outcomes of non-obstetric surgical patients at district hospitals in Rwanda. This study included patients seeking non-obstetric surgical care at three district hospitals in rural Rwanda in 2013. Demographics, surgical conditions, patient care, and outcomes are described; operative and non-operative management were stratified by hospitals and differences assessed using Fisher's exact test. Of the 2660 patients who sought surgical care at the three hospitals, most were males (60.7 %). Many (42.6 %) were injured and 34.7 % of injuries were through road traffic crashes. Of presenting patients, 25.3 % had an operation, with patients presenting to Butaro District Hospital significantly more likely to receive surgery (57.0 %, p < 0.001). General practitioners performed nearly all operations at Kirehe and Rwinkwavu District Hospitals (98.0 and 100.0 %, respectively), but surgeons performed 90.6 % of the operations at Butaro District Hospital. For outcomes, 39.5 % of all patients were discharged without an operation, 21.1 % received surgery and were discharged, and 21.1 % were referred to tertiary facilities for surgical care. Significantly more patients in Butaro, the only site with a surgeon on staff and stronger surgical infrastructure, received surgery. Availing more surgeons who can address the most common surgical needs and improving supplies and equipment may improve outcomes at other districts. Surgical task sharing is recommended as a temporary solution.

To observe the healing status of surgical incisions in human immunodeficiency virus (HIV)-positive patients with fractures and explore the factors related with poor wound healing, treatment and preventive measures. Retrospective analyses were performed for the clinical data of 61 HIV-positive patients with fractures. And the influencing factors, treatment and outcomes of poor wound healing were analyzed. Among them, the healing status was good (n = 50) and poor (n = 11). And the outcomes included redness (n = 10), oozing (n = 8), split (n = 3), infection (n = 2), hematoma (n = 1), fat liquefaction (n = 2) and delayed healing (n = 2). All healed well after treatment. There was no infection or death during the follow-up period. Compared with HIV-negative patients, it was not statistically significant in wound infection. However, poor healing rates were significantly different (P < 0.05). The risk factors included advanced age, low body mass index, low albumin, low hemoglobin, low total lymphocyte count, low CD4⁺ T lymphocyte count, high HIV infection clinical stage, long operative duration, emergency surgery and incision contamination. In HIV-positive patients with fractures, the healing of surgical incision is generally good. However few have poor wound healing due to multiple factors. If poor healing is identified early and handled timely and correctly, good healing ensues.

Changes in collagen in the wound during the healing process of guinea pig skin following surgical incisions and LTW was evaluated using in vivo, using Raman spectroscopy. Raman spectroscopy provided information regarding the internal structure of the proteins. After the incisions were closed either by suturing or by LTW the ratio of the Raman peaks of the amide III (1247 cm-1) band to a peak at 1326 cm-1 used to evaluate the progression of collagen deposition. Histopathology was used as the gold standard. LTW skin demonstrated better healing than sutured skin, exhibiting minimal hyperkeratosis, minimal collagen deposition, near-normal surface contour, and minimal loss of dermal appendages. This work is important to plastic surgery.

The zygornaticomaxillarx complex (ZMC) plays an important role in maintaining the structure and function of the face. The prominent convex shape of the ZMC makes it particularly vulnerable to trauma, resulting in a tetrapod fracture involving all four buttresses. ZMC fracture usually leads to local depressed deformities, even dysfunction such as limited mouth opening and diplopia. This article lescribes the etiology, clinical features, surgical approaches and postoperative complications of ZMC fractures based on our own clinical experiences and literature review. It is believed that lateral brow incision combined with intraoral incision can provide better access to ZMC fractures and avoid the disadvantages caused by coronal incision. This surgical approach leaves minimal scar and injury to the facial nerve, with better esthetic and functional outcomes. Supported by Shanghai Leading Academic Discipline Project (Grant No. Y0203).

Best practices for minimally invasive procedures.

PubMed

Ulmer, Brenda C

2010-05-01

Techniques and instrumentation for minimally invasive surgical procedures originated in gynecologic surgery, but the benefits of surgery with small incisions or no incisions at all have prompted the expansion of these techniques into numerous specialties. Technologies such as robotic assistance, single-incision laparoscopic surgery, natural orifice transluminal endoscopic surgery, and video-assisted thoracoscopic surgery have led to the continued expansion of minimally invasive surgery into new specialties. With this expansion, perioperative nurses and other members of the surgical team are required to continue to learn about new technology and instrumentation, as well as the techniques and challenges involved in using new technology, to help ensure the safety of their patients. This article explores the development of minimally invasive procedures and offers suggestions for increasing patient safety. Copyright 2010 AORN, Inc. Published by Elsevier Inc. All rights reserved.

Laparoscopic Roux-en-Y gastric bypass is the gold standard bariatric procedure. Typically, the procedure necessitates five to seven small skin incisions for trocar placement. The senior author (AA Saber) has developed a three-trocar approach for laparoscopic Roux-en-Y gastric bypass. Sixteen patients underwent triple-incision laparoscopic Roux-en-Y gastric bypass between May 2009 and August 2009. The same surgeon performed all surgical interventions. The umbilicus was the main point of entry for all patients and the same operative technique and perioperative protocol were used in all patients. A total of sixteen triple-incision laparoscopic Roux-en-Y gastric bypasses were performed. The procedures were successfully performed in all patients. Mean operating time was 145.4 min. None of the patients required conversion to an open procedure. There were no mortalities or post-operative technical complications noted during the immediate post-operative period. Three trocar laparoscopic Roux-en-Y gastric bypass is safe, technically feasible and reproducible. This technique may be considered a "precursor" to single-incision laparoscopic Roux-en-Y gastric bypass. Copyright 2009 Surgical Associates Ltd. Published by Elsevier Ltd. All rights reserved.

To analyze the effect of cosmetic outcome as an isolated variable in patients undergoing surgical treatment based on the incision used in the 3 variants of radical prostatectomy: open (infraumbilical incision and Pfannestiel incision) and laparoscopic, or robotic (6 ports) surgery. 612 male patients 40 to 70 years of age with a negative history of prostate disease were invited to participate. Each patient was evaluated by questionnaire accompanied by a set of 6 photographs showing the cosmetic appearance of the 3 approaches, with and without undergarments. Participants ranked the approaches according to preference, on the basis of cosmesis. We also recorded demographic variables: age, body mass index, marital status, education level, and physical activity. Of the 577 patients who completed the questionnaries, the 6-port minimally invasive approach represents the option preferred by 52% of the participants, followed by the Pfannestiel incision (46%), and the infraumbilical incision (11%), respectively. The univariate and multivariate analyses did not show statistically significant differences when comparing the approach preferred by the patients and the sub-analyses for demographic variables, except for patients who exercised who preferred the Pfannestiel incision (58%) instead of minimally invasive approach (42%) with statistically significant differences. The minimally invasive approach was the approach of choice for the majority of patients in the treatment of prostate cancer. The Pfannestiel incision represents an acceptable alternative. More research and investment may be necesary to improve cosmetic outcomes.

To compare the classical double-layer uterine closure to a double-layer purse-string uterine closure (Turan technique) in cesarean section regarding short- and long-term results. Patients were randomized into either the double-layer purse-string uterine closure arm (study group, 84 patients) or the classical double-layer uterine closure arm (control group, 84 patients). For short-term comparison, a detailed transvaginal ultrasound examination was planned in all patients 6 weeks after the operation and a wedge-shaped defect in the uterine incision scar was accepted as uterine scar defect and recorded. For the long-term comparison, subsequent pregnancies of these patients were followed up for any complication. The number of patients with ultrasonographically visible uterine scar defect was 12 (23.5% of all scar defects) in the study group whereas it was 39 (76.5% of all scar defects) in the control group (P < 0.001, χ(2) = 15.42). Demographic data, operation time, hospitalization time, preoperative and postoperative hemoglobin values were not significantly different between the groups. During the 2-year of the follow-up period, five patients in the study group and six patients in the control group became pregnant again. No complication during their pregnancies and second cesarean operation were encountered. With the Turan technique, the uterine incision length becomes shorter, and the frequency of uterine scar defect is lower regarding short-term results. More data is needed for long-term results.

Howell-Taylor, Melania; Hall, Macy G; Brownlee Iii, William J; Taylor, Mary

2008-09-01

Acute infection of surgical incision sites often requires specialized wound care in preparation for surgical closure. Optimal therapy for preparing such wounds for a secondary closure procedure remains uncertain. The authors report wound outcomes after administering acoustic pressure wound therapy in conjunction with negative pressure wound therapy with reticulated open-cell foam dressing changes to assist with bacteria removal from open, infected surgical-incision sites in preparation for secondary surgical closure in three patients. Before incorporating acoustic pressure wound therapy at the authors' facility, the average negative pressure wound therapy with reticulated open-cell foam dressing course prior to secondary surgical closure was 30 days; with its addition, two of three patients underwent successful surgical closure with no postoperative complications after 21 and 14 days, respectively; one patient succumbed to nonwound-related complications before wound closure. Larger, prospective studies are needed to evaluate combining negative pressure wound therapy with reticulated open-cell foam dressing and acoustic pressure wound therapy for infected, acute post surgery wounds.

TRPV1, but not TRPA1, in primary sensory neurons contributes to cutaneous incision-mediated hypersensitivity

PubMed Central

2013-01-01

Background Mechanisms underlying postoperative pain remain poorly understood. In rodents, skin-only incisions induce mechanical and heat hypersensitivity similar to levels observed with skin plus deep incisions. Therefore, cutaneous injury might drive the majority of postoperative pain. TRPA1 and TRPV1 channels are known to mediate inflammatory and nerve injury pain, making them key targets for pain therapeutics. These channels are also expressed extensively in cutaneous nerve fibers. Therefore, we investigated whether TRPA1 and TRPV1 contribute to mechanical and heat hypersensitivity following skin-only surgical incision. Results Behavioral responses to mechanical and heat stimulation were compared between skin-incised and uninjured, sham control groups. Elevated mechanical responsiveness occurred 1 day post skin-incision regardless of genetic ablation or pharmacological inhibition of TRPA1. To determine whether functional changes in TRPA1 occur at the level of sensory neuron somata, we evaluated cytoplasmic calcium changes in sensory neurons isolated from ipsilateral lumbar 3–5 DRGs of skin-only incised and sham wild type (WT) mice during stimulation with the TRPA1 agonist cinnamaldehyde. There were no changes in the percentage of neurons responding to cinnamaldehyde or in their response amplitudes. Likewise, the subpopulation of DRG somata retrogradely labeled specifically from the incised region of the plantar hind paw showed no functional up-regulation of TRPA1 after skin-only incision. Next, we conducted behavior tests for heat sensitivity and found that heat hypersensitivity peaked at day 1 post skin-only incision. Skin incision-induced heat hypersensitivity was significantly decreased in TRPV1-deficient mice. In addition, we conducted calcium imaging with the TRPV1 agonist capsaicin. DRG neurons from WT mice exhibited sensitization to TRPV1 activation, as more neurons (66%) from skin-incised mice responded to capsaicin compared to controls (46%), and the sensitization occurred specifically in isolectin B4 (IB4)-positive neurons where 80% of incised neurons responded to capsaicin compared to just 44% of controls. Conclusions Our data suggest that enhanced TRPA1 function does not mediate the mechanical hypersensitivity that follows skin-only surgical incision. However, the heat hypersensitivity is dependent on TRPV1, and functional up-regulation of TRPV1 in IB4-binding DRG neurons may mediate the heat hypersensitivity after skin incision injury.

Although a variety of techniques for upper blepharoplasty have been described, few studies illustrate and clinically evaluate a system for marking incisions. Presented is a 10-year experience using a specific method for marking upper blepharoplasty incisions that consistently yielded excellent esthetic results. All upper blepharoplasties performed by the senior author between April, 1994 and April, 2004 were reviewed. Markings were designed to end the medial incision 6 mm from the angular vein, end the lateral incision 12 mm from the palpebral fissure, and to extend the incisions superiorly at 45 degrees. Over 10 years, 476 patients underwent cosmetic upper blepharoplasty. There were 22 (4.6%) revisions. Eighteen (3.8%) were performed in clinic using CO2 laser, and 4 (0.8%) patients required surgical revision. Patient satisfaction was high, and no scars were visible outside the brow. Excellent outcomes can be expected using this simple, reproducible, and widely applicable system for marking upper blepharoplasty incisions.

Evaluate the capacity of government-run hospitals in Bangladesh to provide emergency and essential surgical, obstetric and anaesthetic services. Cross-sectional survey of 240 Bangladeshi Government healthcare facilities using the World Health Organisation Situational Analysis Tool to Assess Emergency and Essential Surgical Care (SAT). This tool evaluates the ability of a healthcare facility to provide basic surgical, obstetric and anaesthetic care based on 108 queries that detail the infrastructure and population demographics, human resources, surgical interventions and reason for referral, and available surgical equipment and supplies. For this survey, the Bangladeshi Ministry of Health sent the SAT to sub-district, district/general and teaching hospitals throughout the country in April 2013. Responses were received from 240 healthcare facilities (49.5% response rate): 218 sub-district and 22 district/general hospitals. At the sub-district level, caesarean section was offered by 55% of facilities, laparotomy by 7% and open fracture repair by 8%. At the district/general hospital level, 95% offered caesarean section, 86% offered laparotomy and 77% offered open fracture treatment. Availability of anaesthesia services, general equipment and supplies reflected this trend, where district/general hospitals were better equipped than sub-district hospitals, though equipment and infrastructure shortages persist. There has been overall impressive progress by the Bangladeshi Government in providing essential surgical services. Areas for improvement remain across all key areas, including infrastructure, human resources, surgical interventions offered and available equipment. Investment in surgical services offers a cost-effective opportunity to continue to improve the health of the Bangladeshi population and move the country towards universal healthcare coverage.

To search for a simple and effective surgical approach to the management of moderate to severe pediatric concealed penis in children. We used Devine's technique via incision between the penis and scrotum in the treatment of 68 cases of moderate to severe pediatric concealed penis. The patients were aged 3 -13 (mean 6.5) years, 30 with moderate and 38 with severe pediatric concealed penis. This strategy achieved good near- and long-term effects and satisfactory appearance of the penis, which was similar to that of circumcision. At 3 months after surgery, the penile length was 3 - 5.2 cm, averaging (2.35 +/- 0.35) cm. Devine's technique via incision between the penis and scrotum is a simple and effective surgical option for moderate to severe pediatric concealed penis in children.

The objective of this study is to test the null hypothesis that an S-shaped surgical incision versus conventional (straight) skin incision in the creation of autogenous radiocephalic arteriovenous fistulas (RCAVFs) have no impact on the primary end-point of primary functional maturation and secondary end points of stenosis and thrombosis. A prospective observational comparative consecutive study with intention-to-treat on individuals undergoing only radiocephalic arteriovenous fistula (RCAVFs) over a period of 12 months was conducted. Variables on patient's demographics, comorbidities, anesthesia type, mean arterial blood pressure, thrill, laterality, cephalic vein and radial artery diameter were collated. The test of probability was assessed through Chi-Square, Kaplan-Meier survival estimator and Log-Rank analysis. Total of n = 83 individuals with median age of 67 years (IQR, 20-89) and male predominance 83% during this period were subjected to RCAVF formation. Total of n = 45 patients in straight skin incision were compared to n = 38 individuals in S-shaped group. Despite equal prevalence of demographics, comorbidities, anesthesia type, mean arterial blood pressure (MAP), thrill, laterality, cephalic vein and radial artery diameter ( p  > 0.05) higher incidence of juxta-anastomotic stenosis was noted in the straight skin incision group ( p  = 0.029) in comparative and survival analysis (Log-Rank, p  = 0.036). The maturation of the entire cohort was 69% (S-shaped 76% vs. straight group 62%) (p > 0.05). The outcome of this study demonstrates that S-shaped surgical skin incision is associated with a lower incidence of stenosis in comparison to straight incision type in RCAVF formation.

This study aims to describe patient demographics, visual and surgical outcomes of a cohort undergoing small incision cataract surgery at a Pacific regional ophthalmic training facility. This is a prospective, longitudinal study conducted at the Pacific Eye Institute, Fiji. One hundred fifty-six patients underwent small incision cataract surgery. Preoperatively, a complete ophthalmic examination, including pachymetry and macular optical coherence tomography performed by two independent investigators. Temporal small incision cataract surgery with intraocular lens insertion was performed by ophthalmologists, and trainee ophthalmologists. Follow-up occurred at day one, four weeks and 3 months. Patient characteristics, visual outcomes including surgically induced astigmatism and complications. Ninety-one per cent (142/156) attended 3-month follow-up with median age 63 years (range 19-82), 52% female (81/156) and 58% (90/156) Fijian ethnicity. In 37% (57/156), the contralateral eye was pseudophakic. Mean preoperative best spectacle-corrected visual acuity was logMAR 1.44 (6/165). At 3 months, 74% (105/142) achieved ≥6/18 unaided vision (94% [133/142] best spectacle-corrected visual acuity). Mean postoperative spherical equivalent was -0.78 (SD 0.95) D and mean surgically induced astigmatism 1.04 (0.57) D. Complications included posterior capsular rupture with vitreous loss (4% [6/156]), optical coherence tomography confirmed macular oedema (8% [12/152] at 4 weeks), significant posterior capsular opacity (23% [31/136]) and >5% increase in preoperative pachymetry (1% [1/142]) at 3 months. Reduction in preoperative best spectacle-corrected visual acuity occurred in 2% (3/142). No cases of endophthalmitis. Small incision cataract surgery provided to a regional population is effective with 94% achieving the World Health Organisation's definition of 'Good Vision' (≥6/18). Refinements in biometric and surgical techniques may allow a greater proportion of patients to achieve good unaided vision. © 2017 Royal Australian and New Zealand College of Ophthalmologists.

Living donor hepatectomy is now a well-established surgical procedure. However, a large abdominal incision is still required, which results in a large permanent scar, especially for a right liver graft. This report reviews our techniques of minimally invasive or minimal incisional donor hepatectomy using a transverse incision.Twenty-five living donors underwent right hepatectomy with a transverse incision and 484 donors with a conventional incision between April 2007 and December 2012. Among the donors with a transverse incision, two cases were totally laparoscopic procedures using a hand-port device; 11 cases were laparoscopic-assisted hepatectomy (hybrid technique), and 14 cases were open procedures using a transverse incision without the aid of the laparoscopic technique. Currently, a hybrid method has been exclusively used because of the long operation time and surgical difficulty in totally laparoscopic hepatectomy and the exposure problems for the liver cephalic portion during the open technique using a transverse incision.All donors with a transverse incision were women except for one. Twenty-four of the grafts were right livers without middle hepatic vein (MHV) and one with MHV. The donors' mean BMI was 21.1 kg/m. The median operation time was 355 minutes, and the mean estimated blood loss was 346.1±247.3 mL (range, 70-1200). There was no intraoperative transfusion. These donors had 29 cases of grade I [14 pleural effusions (56%), 11 abdominal fluid collections (44%), 3 atelectasis (12%), 1bile leak (4%)], 1 case of grade II (1 pneumothorax) and two cases of grade III complications; two interventions were needed because of abdominal fluid collections by Clavien-Dindo classification. Meanwhile, donors with a conventional big incision, which included the Mercedes-Benz incision or an inverted L-shaped incision, had 433 cases of grade I, 19 cases of grade II and 18 cases of grade III complications. However, the liver enzymes and total bilirubin of all donors were normalized within 1 month, and they recovered fully. Additionally, in a survey inquiring about cosmetic outcomes with a numeric scale of 1 through 10 (1, Not confident; 10, Very confident), the transverse incision had more satisfactory scores compared to the conventional big incision (9.80 vs. 6.17, P=0.001). In conclusion, the hybrid technique can be safely performed in donor right hepatectomy, with a minimal transverse skin incision, resulting in a good cosmetic outcome.

Five sugar gliders ( Petaurus breviceps ), ranging in age from 3 mo to 3.5 yr of age, and one opossum ( Didelphis virginianus ), age 4.5 mo, presented for elective orchiectomy and scrotal ablation. The LigaSure™ device was safely used for orchiectomy and scrotal ablation in both species. Surgical time with the LigaSure was approximately 4 sec. No grooming of the incision site or self-mutilation was seen in the first 72 hr postoperatively. One sugar glider required postoperative wound care approximately 10 days postoperatively following incision-site grooming by a conspecific. The LigaSure provides a rapid, technologically simple and safe surgical technique for scrotal ablation and orchiectomy in the marsupial patient that minimizes surgical, anesthetic, and recovery times.

The article addresses issues of comparative characterization of deliveries involving surgery and impact thereof on the health of the mother and her child. Risk factors are identified that the mother and her child run in sectio cesarea, in application of obstetrical forceps, and in vacuum-extraction of the fetus. Cesarean section was found out to be the most acceptable mode of delivery in origination of organic and functional nervous system involvement in children but the most ill-chosen and unpropitious one in the mother, especially so in those groups at risk for bleeding, septic complications, and genital endometriosis. Among those surgical methods of delivery being the least traumatic to the mother are obstetrical forceps and vacuum-extraction of the fetus.

Abscess incision and drainage in the emergency department--Part I.

PubMed

Halvorson, G D; Halvorson, J E; Iserson, K V

1985-01-01

Superficial abscesses are commonly seen in the emergency department. In most cases, they can be adequately treated by the emergency physician without hospital admission. Treatment consists of surgical drainage with the addition of antibiotics in selected cases. Incision is generally performed using local anesthesia, with intraoperative and postoperative systemic analgesia. Care must be taken to make a surgically appropriate incision that allows adequate drainage without injuring important structures. Postoperative care includes warm soaks, drains or wicks, analgesia, and close follow-up. Antibiotics are usually unnecessary. Complications of incision and drainage include damage to adjacent structures, bacteremic complications, misdiagnosis of such entities as mycotic aneurysms, and spread of infection owing to inadequate drainage. The infectious agents responsible for abscess formation are numerous and depend largely on the anatomic location of the abscess. Staphylococcus aureus accounts for less than half of all cutaneous abscesses. Anaerobic bacteria are common etiologic agents in the perineum and account for the majority of all cutaneous abscesses. Abscesses at specific locations involve special consideration for diagnosis and treatment and may require specialty consultation.

Early surgical suction and washout for treatment of cytotoxic drug extravasations.

Vandeweyer, E; Deraemaecker, R

2000-02-01

This case report is presented to assess safety and efficiency of early suction and saline washout of extravasated cytotoxic drugs. Through multiple small skin incisions, the area of extravasation is first suctioned and subsequently extensively washed out with saline. Incisions are left open and the arm is elevated for 24 hours. A complete healing was obtained in five days without any skin or soft tissue loss. No additional treatment was needed. Early referral and surgical treatment by suction and washout is a safe and reliable treatment protocol for major cytotoxic drug extravasation injuries.

2011-01-01

Atrophic edentulous mandible fractures in geriatric patients have low incidence but present several biological and biomechanical peculiarities that produce a nonunion rate of around 20%. Surgical extraoral approaches for internal fixation of these fractures can be transcervical or by one or two submandibular incisions. Two patients sustaining multiple fractures in atrophic edentulous mandible are presented: the first patient was 72-years-old, treated by two submandibular incisions, and the second was 81-years-old, treated by transcervical approach. We discuss the advantages and drawbacks of each approach and their indications according to the Luhr et al (1996) atrophy index. PMID:22379503

2017-08-01

Open surgical approaches to treat tibial avulsion fractures of the posterior cruciate ligament (PCL) often use large incisions involving extensive muscle dissection and retraction. The objective of this study was to describe a new mini-invasive approach targeting the fractured zone, to minimize surgical dissection and improve recovery and rehabilitation. The new approach was used in 15 males and seven females with isolated PCL avulsions. The length of the surgical incision, surgical time, need for conversion to open technique, visual analog scores (VAS) and duration of hospital stay were studied to assess the efficacy, learning curve and advantages of the new technique. Neurovascular complications were recorded. At the two-year follow-up, International Knee Documentation Committee (IKDC) scores were recorded to assess function. Patients were followed up for a mean of 29months (range: 34-41). The mean length of the incision was 4.1cm (range: 3.4 to five) measured at the end of the procedure. None of the patients required conversion to an open technique and no neurovascular complications were recorded. The mean surgical time was 40min (range: 25-50). The mean VAS on discharge was 2.2 (range: one to four) and patients stayed at the hospital for a mean of 2.2days (range: one to three). The mean IKDC score at one-year post surgery was 86.4 (range: 83.9-90.8). The new mini-invasive targeted approach provides adequate exposure for performing internal fixation of PCL avulsion fractures without the surgical morbidity associated with conventional open surgical approaches. The procedure is safe, fast and does not require a long learning curve. Copyright © 2017 Elsevier B.V. All rights reserved.

Specialty procedures constitute one eighth of rural surgery practice. Currently, general surgeons intending to practice in rural hospitals may not get adequate training for specialty procedures, which they will be expected to perform. Better definition of these procedures will help guide rural surgery training. Current Procedural Terminology codes for all surgical procedures for 81% of North Dakota and South Dakota rural surgeons were entered into the Dakota Database for Rural Surgery. Specialty procedures were analyzed and compared with the Surgical Council on Resident Education curriculum to determine whether general surgery training is adequate preparation for rural surgery practice. The Dakota Database for Rural Surgery included 46,052 procedures, of which 5,666 (12.3%) were specialty procedures. Highest volume specialty categories included vascular, obstetrics and gynecology, orthopedics, cardiothoracic, urology, and otolaryngology. Common procedures in cardiothoracic and vascular surgery are taught in general surgical residency, while common procedures in obstetrics and gynecology, orthopedics, urology, and otolaryngology are usually not taught in general surgery training. Optimal training for rural surgery practice should include experience in specialty procedures in obstetrics and gynecology, orthopedics, urology, and otolaryngology. Copyright © 2012 Elsevier Inc.

2011-09-01

To evaluate the effectiveness of surgical sealant (CoSeal) in sealing the tracheal assess sites after transtracheal thoracoscopy. Two dogs underwent transtracheal thoracic exploration and pericardial window creation. The thoracic cavity was approached with flexible bronchoscope through a 9-mm tracheal incision. The pericardial window was performed with a needle knife via the working channel of the bronchoscope, and the tracheal assess site was closed with CoSeal using a rubber catheter. The integrity of tracheal healing was evaluated under positive pressure ventilation. Transtracheal creation of pericardial window and closure of tracheal incision with CoSeal was successfully performed in both dogs. There was no evidence of air leaks from the chest tube during positive pressure ventilation. Autopsy revealed no injury to the mediastinum and intrathoracic structure. Endoscopic closure of tracheal access site of NOTES with CoSeal appears to be a feasible technique.

Obstetric balloon for treatment of foreshortened vagina using the McIndoe technique.

PubMed

Rauktys, Aubrey; Parikh, Pranay; Harmanli, Oz

2015-01-01

When conservative options such as the use of vaginal dilators fail, the McIndoe technique may be used in the surgical treatment of a foreshortened vagina. The McIndoe procedure, an approach commonly used for the treatment of vaginal agenesis, requires a mold over which a skin graft is sutured and placed inside the vagina. In most surgical descriptions, this mold is made from non-sterile foam, condoms, or gloves. Because makeshift molds can no longer be used in operating rooms owing to strict regulations, alternative methods must be employed. The obstetric balloon is a good choice for use as a soft and adjustable vaginal mold for a modified McIndoe procedure because it is readily available as an approved device in hospitals that provide obstetric services. This technique was successfully employed in a 54-year-old woman to treat foreshortened vagina. An obstetric balloon can be used effectively as a mold for vaginal reconstruction with the McIndoe technique.

The perceived difficulty of steps of manual small incision cataract surgery among trainees in rural China was assessed. Cohort study. Fifty-two trainees at the end of a manual small incision cataract surgery training programme. Participants rated the difficulty of 14 surgical steps using a 5-point scale, 1 (very easy) to 5 (very difficult). Demographic and professional information was recorded for trainees. Mean ratings for surgical steps. Questionnaires were completed by 49 trainees (94.2%, median age 38 years, 8 [16.3%] women). Twenty six (53.1%) had performed ≤50 independent cataract surgeries prior to training. Trainees rated cortical aspiration (mean score ± standard deviation = 3.10 ± 1.14) the most difficult step, followed by wound construction (2.76 ± 1.08), nuclear prolapse into the anterior chamber (2.74 ± 1.23) and lens delivery (2.51 ± 1.08). Draping the surgical field (1.06 ± 0.242), anaesthetic block administration (1.14 ± 0.354) and thermal coagulation (1.18 ± 0.441) were rated easiest. In regression models, the score for cortical aspiration was significantly inversely associated with performing >50 independent manual small incision cataract surgery surgeries during training (P = 0.01), but not with age, gender, years of experience in an eye department or total number of cataract surgeries performed prior to training. Cortical aspiration, wound construction and nuclear prolapse pose the greatest challenge for trainees learning manual small incision cataract surgery, and should receive emphasis during training. Number of cases performed is the strongest predictor of perceived difficulty of key steps. © 2013 The Authors.

Organ shortage has led to using grafts from expanded criteria donors (ECD). Double kidney transplantation is an accepted strategy to increase the donor pool, using organs from an ECD which are not acceptable for single kidney transplantation (SKT). Aim of this retrospective study was to analyse the role of colour Doppler ultrasound (CDUS) in the diagnosis of major surgical complications in DKT, performed with unilateral or bilateral placement. From 2000 to 2011 we performed 54 DKT. Unilateral placement of both kidneys was done in 26 patients and bilateral DKT in 28, through two separate Gibson incisions (18) or one midline incision (10). Each patient underwent at least 3 CDUS before hospital discharge. The main surgical complications, discovered initially thanks to ultrasound (US), were hydronephrosis from ureteral obstruction, lymphocele and deep venous thrombosis (DVT). Mean follow-up was 42.7 months. Good postoperative renalfunction was demonstrated in 25 patients (46.3%), while delayed graft function occurred in 29 (53.7%). US showed ureteral obstruction requiring surgery in 5 unilateral DKT while no patient subjected to bilateral DKT developed severe hydronephrosis. Lymphoocele, surgically drained, was demonstrated in 6 bilateral DKT with a midline incision, 2 bilateral DKT with two separate incisions and 3 unilateral DKT. CDUS also enabled diagnosis of 2 cases of DVT in ipsilateral DKTs. CDUS provides useful information in patients with DKT, allowing the detection of clinically unsuspected unilateral diseases. US study of our patients demonstrated that unilateral DKTs are more susceptible to the development of DVT and ureteral stricture, while the incidence of voluminous lymphocele is more frequent in bilateral DKT through a single midline incision. In this scenario, all patients undergoing DKT should be carefully monitored by US after surgery.

Single-incision laparoscopic surgery (SILS) is gaining popularity for a wide variety of surgical operations and capitalizes on the benefits of traditional laparoscopic surgery without incurring multiple incision sites. Traditionally, SILS is performed by a midline periumbilical approach. However, such a minimally invasive approach may be utilized in patients who already have an abdominal incision. Our series retrospectively reviews 7 cases in which we utilized the fascial defect at the time of after ostomy reversal as our SILS incision site. In turn, we performed a variety of concurrent intra-abdominal procedures with excellent technical success and outcomes. Our study is the largest single-institution case series of this novel approach and suggests that utilizing an existing ostomy-site abdominal incision is a safe and effective location for SILS port placement and should be considered in patients undergoing concurrent procedures.

To evaluate the effect of surgical factors on postoperative astigmatism in infants undergoing cataract extraction with or without intraocular lens (IOL) implantation. The Infant Aphakia Treatment Study is a multicenter clinical trial in which 114 infants with unilateral congenital cataracts were randomized to undergo cataract extraction with IOL placement or contact lens aphakic correction. Surgical videos were reviewed with regard to incision type and location, whether the incision was extended, the number of sutures placed, and technique of closure. Corneal astigmatism was measured using a handheld keratometer prior to surgery and at 1 year of age. Corneal astigmatism decreased from a mean of 1.92 D at baseline to 1.62 D at age 1 year in the contact lens group but remained almost unchanged from 2.00 D to 2.09 D in the IOL group (P = 0.023). There was no statistical difference between the amount of corneal astigmatism with regard to incision type (P = 0.214) and no increase in astigmatism with extension of the incision to facilitate IOL placement (P = 0.849) at 1 year. The number of sutures and technique of closure did not influence the amount of astigmatism at 1 year. At the age of 1 year following cataract extraction in infants, contact lens correction and the lack of IOL placement are associated with a significant decrease in postoperative corneal astigmatism compared to IOL placement. No other surgical factors considered in this study had a statistically significant effect on corneal astigmatism. Copyright © 2014 American Association for Pediatric Ophthalmology and Strabismus.

Wound healing inevitably leads to scarring, which leads to functional and cosmetic defects. It is the goal of this study to investigate the immediate use of ablative fractional CO 2 lasers to reduce post-operative scarring secondary to surgical wounds. In this prospective controlled study, 20 surgical incisions were created on each of three pigs. Fifteen of the incisions were treated with an ablative fractional CO 2 laser at one of three laser settings. The remaining five incisions served as a control. Punch biopsies were taken post-operatively over time. Digital photographs were taken of each incisional scar at each time period. Blinded evaluators used a previously verified scoring system to score photographs of the incisional scars taken at the 6 month time period. With regards to the comparison between the three individual laser treatment groups and the control, there were no statistically significant effects for treatment (P = 0.40), time (P = 0.48), or for the interaction of time and treatment (P = 0.57). With regards to the visual assessment tool, there were no statistically significant differences between treatments for Overall Appearance (P = 0.21) or for Total Score (P = 0.24). In the limited setting of this pilot study, treatment of surgical incisions with ablative fractional CO 2 lasers does not significantly lessen scar formation. In addition, photographic analysis was not able to demonstrate a significant difference. Future studies on this topic will need a larger sample size to better answer whether a statistically significant difference may exist. Lasers Surg.

Embedment of metallic foreign bodies in the soft tissues is commonly encountered in the emergency room. Most foreign bodies are easily removed, but removal is difficult if the foreign body is very small or deeply embedded. To determine the usefulness of methylene blue staining in the surgical removal of tiny metallic foreign bodies embedded in the soft tissue. This prospective study involved 41 children treated between May 2007 and May 2012. The patients were randomly divided into a methylene blue group and a control group. In the control group, foreign bodies were located using a C-arm and removed via direct incision. In the methylene blue group, foreign bodies were located using a C-arm, marked with an injection of methylene blue and then removed surgically. The clinical outcomes, complications, operation time, surgical success rate, incision length, frequency of C-arm use, and length and depth of the foreign body were compared between the two groups. The surgical success rate was significantly higher in the methylene blue group. The average operation time was significantly shorter in the methylene blue group. The C-arm was used significantly less frequently in the methylene blue group than in the control group. The incision length was significantly shorter in the methylene blue group than in the control group. Methylene blue staining facilitated the location and removal of tiny metallic foreign bodies from the soft tissue, and significantly reduced operation time, incision length and radiation exposure compared to the conventional method.

2007-03-01

Burn contractures particularly involving the joints are challenging problems which might cause severe functional impairments. Many surgical techniques have been described for use, however, an ideal method yet to be found. Releasing incision is the most common and effective way to release the wide and severe contractures but it has some drawbacks. We propose a releasing incision technique combined with four Z plasty incisions to overcome the disadvantages of traditional releasing incision technique. We successfully used our releasing incision and quadra Z technique on seven consecutive patients with burn contractures between 2003 and 2005. We modified the classical releasing incision technique by adding four Z plasties; two of them with a common base on each corner of the incision line. In this technique, limitation of the webbing following the incision is made possible by the transposed flaps and unnecessary lateral extension of the incision and the defect was avoided, i.e. maximum release gain with minimal defect was provided. Satisfactory results were achieved in seven patients treated with this technique due to significant burn contractures between 2003 and 2005 with no significant complication. We propose this technique is suitable in all patients with severe burn contractures who require releasing incision and grafting.

Increasing experience with minimally invasive surgery and the development of new instruments has resulted in a tendency toward reducing the number of abdominal skin incisions. Retrospective and randomized prospective studies could show the feasibility of single-incision surgery without any increased risk to the patient. However, large prospective multicenter observational datasets do not currently exist. This prospective multicenter observational quality study will provide a relevant dataset reflecting the feasibility and safety of single-incision surgery. This study focuses on external validity, clinical relevance, and the patients' perspective. Accordingly, the single-incision multiport/single port laparoscopic abdominal surgery (SILAP) study will supplement the existing evidence, which does not currently allow evidence-based surgical decision making. The SILAP study is an international prospective multicenter observational quality study. Mortality, morbidity, complications during surgery, complications postoperatively, patient characteristics, and technical aspects will be monitored. We expect more than 100 surgical centers to participate with 5000 patients with abdominal single-incision surgery during the study period. Funding was obtained in 2012. Enrollment began on January 01, 2013, and will be completed on December 31, 2018. As of January 2016, 2119 patients have been included, 106 German centers are registered, and 27 centers are very active (>5 patients per year). This prospective multicenter observational quality study will provide a relevant dataset reflecting the feasibility and safety of single-incision surgery. An international enlargement and recruitment of centers outside of Germany is meaningful.

Fisheries research involving surgical implantation of transmitters necessitates the use of methods that minimize transmitter loss and fish mortality and optimize healing of the incision. We evaluated the effects of three incision locations on transmitter loss, healing, survival, growth, and suture retention in juvenile Chinook salmon Oncorhynchus tshawytscha. The three incision locations were (1) on the linea alba (LA incision), (2) adjacent and parallel to the LA (muscle-cutting [MC] incision), and (3) extending from the LA towards the dorsum at a 45° angle, between the parallel lines of myomeres (muscle-sparing [MS] incision). A Juvenile Salmon Acoustic Telemetry System acoustic transmittermore » (0.44 g in air) and a passive integrated transponder tag (0.10 g in air) were implanted into each fish (total N = 936 fish). The fish were held at 12°C or 20°C and were examined weekly for 98 d. The progression of healing among incision locations and the variability in transmitter loss made it difficult to identify one incision location as the best choice. The LA incisions had a much smaller wound extent (area of visible subepidermal tissue) than MC and MS incisions during the first 28 d of the study. In both temperature treatments, apposition of incisions through day 14 was better for LA incisions than for MC and MS incisions. However, MC and MS incisions were less likely than LA incisions to reopen over time and thus were less likely to allow transmitter loss through the incision.« less

Gynecomastia is characterized by the benign proliferation of breast tissue in men. Herein, we present a new method for the treatment of gynecomastia, using ultrasound-assisted liposuction with both conventional and reverse-cutting edge tip cannulas in combination with a pull-through lipectomy technique with pituitary forceps through a single transaxillary incision. Thirty patients were treated with this technique at the author's institution from January 2010 to January 2015. Ten patients were treated with conventional surgical excision of the glandular/fibrous breast tissue combined with liposuction through a periareolar incision before January 2010. Medical records, clinical photographs and linear analog scale scores were analyzed to compare the surgical results and complications. The patients were required to rate their cosmetic outcomes based on the linear analog scale with which they rated their own surgical results; the mean overall average score indicated a good or high level of satisfaction. There were no incidences of skin necrosis, hematoma, infection and scar contracture; however, one case each of seroma and nipple inversion did occur. Operative time was reduced overall using the new technique since it is relatively simple and straightforward. According to the evaluation by the four independent researchers, the patients treated with this new technique showed statistically significant improvements in scar and nipple-areolar complex (NAC) deformity compared to those who were treated using the conventional method. Glandular liposculpture through a single transaxillary incision is an efficient and safe technique that can provide aesthetically satisfying and consistent results.

Short-term pre- and post-operative stress prolongs incision-induced pain hypersensitivity without changing basal pain perception.

Chronic stress has been reported to increase basal pain sensitivity and/or exacerbate existing persistent pain. However, most surgical patients have normal physiological and psychological health status such as normal pain perception before surgery although they do experience short-term stress during pre- and post-operative periods. Whether or not this short-term stress affects persistent postsurgical pain is unclear. In this study, we showed that pre- or post-surgical exposure to immobilization 6 h daily for three consecutive days did not change basal responses to mechanical, thermal, or cold stimuli or peak levels of incision-induced hypersensitivity to these stimuli; however, immobilization did prolong the duration of incision-induced hypersensitivity in both male and female rats. These phenomena were also observed in post-surgical exposure to forced swimming 25 min daily for 3 consecutive days. Short-term stress induced by immobilization was demonstrated by an elevation in the level of serum corticosterone, an increase in swim immobility, and a decrease in sucrose consumption. Blocking this short-term stress via intrathecal administration of a selective glucocorticoid receptor antagonist, RU38486, or bilateral adrenalectomy significantly attenuated the prolongation of incision-induced hypersensitivity to mechanical, thermal, and cold stimuli. Our results indicate that short-term stress during the pre- or post-operative period delays postoperative pain recovery although it does not affect basal pain perception. Prevention of short-term stress may facilitate patients' recovery from postoperative pain.

The present study aimed to discuss the advantage of the application of a cervical low incision for functional neck dissection in patients with thyroid papillary carcinoma. The study was a retrospective analysis of 87 thyroid papillary carcinoma patients; cervical low incision in the functional neck dissection was applied for 47 cases and the classic 'L' incision was applied for 40 cases. The different integrity, surgical time, blood loss and the aesthetic property of the incision were compared between the cervical low incision and the classic 'L' incision for lateral neck dissection of thyroid cancer. The postoperative pathological diagnosis was that the average total amount and the region II lymph nodes of the unilateral neck dissection were 33 and 10 for the cervical low incision group, and 32 and 11 for the classic 'L' incision group, respectively (P>0.05). The average unilateral neck dissection times were 87 and 58 min for the cervical low incision group and the classic 'L' incision group, respectively (P<0.05). The blood loss of the cervical low incision group was 67 ml, while the loss for the classic 'L' incision group was 61 ml (P>0.05). The postoperative incision of the cervical low incision group was smaller and more concealing. Additionally, the cosmetic deformities were milder for an inconspicuous cervical scar, and the sensation was improved for the patients in comparison with the classic 'L' incision group. These results suggest that the application of cervical low incision for functional neck dissection in thyroid papillary carcinoma patients aids in reducing postoperative complications, without increasing recurrence rates. Therefore, the classic 'L' incision can be replaced by the cervical low incision.

The present study aimed to discuss the advantage of the application of a cervical low incision for functional neck dissection in patients with thyroid papillary carcinoma. The study was a retrospective analysis of 87 thyroid papillary carcinoma patients; cervical low incision in the functional neck dissection was applied for 47 cases and the classic ‘L’ incision was applied for 40 cases. The different integrity, surgical time, blood loss and the aesthetic property of the incision were compared between the cervical low incision and the classic ‘L’ incision for lateral neck dissection of thyroid cancer. The postoperative pathological diagnosis was that the average total amount and the region II lymph nodes of the unilateral neck dissection were 33 and 10 for the cervical low incision group, and 32 and 11 for the classic ‘L’ incision group, respectively (P>0.05). The average unilateral neck dissection times were 87 and 58 min for the cervical low incision group and the classic ‘L’ incision group, respectively (P<0.05). The blood loss of the cervical low incision group was 67 ml, while the loss for the classic ‘L’ incision group was 61 ml (P>0.05).

The diagnosis of a complete acromioclavicular separation (Tossy III) is a indication for a surgical repair. Many and different methods are reported in history. 33 patients with a fresh, complete acromioclavicular separation are treated at the BG-Unfallklinik Tübingen from 1. 1. 1970--31. 12. 1978 by suturing the ligaments, inserting pins across the joint and tension-bending. With this method good results have been achieved, possible intra- and postoperative complications are reported. The incision along the clavicula gives quite often scar problems. Therefore we now use an arched incision across the AC-joint.

Nipple-sparing mastectomy (NSM) is increasingly popular for the treatment of selected breast cancers and prophylactic mastectomy. Surgical scarring and esthetic outcomes are important patient-related cosmetic considerations. Today, the concept of minimally invasive surgery has become popular, especially using robotic surgery. The authors report the first case of NSM using the latest version of the da Vinci Xi surgical system (Xi). The final incision used to remove the entire mammary gland was located behind the axillary line. In this position, hidden by the arm of the patient, the incision was not visible and was compatible with immediate breast reconstruction. © 2017 Wiley Periodicals, Inc.

Background and Objective As a result of wound healing the original tissue is replaced by dysfunctional scar tissue. Reduced tissue damage during surgical procedures beneficially affects the size of the resulting scar and overall healing time. Thus the choice of a particular surgical instrument can have a significant influence on the postoperative wound healing. To overcome these problems of wound healing we applied a novel picosecond infrared laser (PIRL) system to surgical incisions. Previous studies indicated that negligible thermal, acoustic, or ionization stress effects to the surrounding tissue results in a superior wound healing. Study Design/Materials and Methods Using the PIRL system as a surgical scalpel, we performed a prospective wound healing study on rat skin and assessed its final impact on scar formation compared to the electrosurgical device and cold steel. As for the incisions, 6 full‐thickness, 1‐cm long‐linear skin wounds were created on the dorsum of four rats using the PIRL, an electrosurgical device, and a conventional surgical scalpel, respectively. Rats were euthanized after 21 days of wound healing. The thickness of the subepithelial fibrosis, the depth and the transverse section of the total scar area of each wound were analyzed histologically. Results After 21 days of wound healing the incisions made by PIRL showed minor scar tissue formation as compared to the electrosurgical device and the scalpel. Highly significant differences (P < 0.001) were noted by comparing the electrosurgical device with PIRL and scalpel. The transverse section of the scar area also showed significant differences (P = 0.043) when comparing PIRL (mean: 141.46 mm2; 95%CI: 105.8–189.0 mm2) with scalpel incisions (mean: 206.82 mm2; 95%CI: 154.8–276.32 mm2). The subepithelial width of the scars that resulted from using the scalpel were 1.3 times larger than those obtained by using the PIRL (95%CI: 1.0–1.6) though the difference was not significant (P < 0.083). Conclusions The hypothesis that PIRL results in minimal scar formation with improved cosmetic outcomes was positively verified. In particular the resection of skin tumors or pathological scars, such as hypertrophic scars or keloids, are promising future fields of PIRL application. Lasers Surg.

To explore the relationship between CD4(+) T lymphocyte cell count and prognosis as well as healing of the surgical incision in HIV/AIDS patients who had received operation. Data were collected and analysed retrospectively from 234 HIV/AIDS patients hospitalized at the Beijing Ditan hospital who underwent operation between January 2008 and December 2012. Following factors were taken into consideration that including:age, gender, time and where that anti-HIV(+) was diagnosed, CD4(+)T lymphocyte cell count at the time of operation, part of the body that being operated, typology of incision, different levels of healing on the surgical incision, infection at the incision site, post-operative complications and the prognosis, etc. Wilcoxon rank sum test, χ(2) test, Kruskal-Wallis H test and Spearman rank correlation were used for statistical analysis to compare the different levels on healing of the incision in relation to the different CD4(+)T lymphocyte cell counts. Rates of level A healing under different CD4(+)T cell counts were also compared. 1) Among the 234 patients including 125 males and 109 females, the average age was 36.17±11.56 years old. Time after discovery of anti-HIV(+)was between 0 and 204 months. The medium CD4(+)T cell count was 388.5 cell/µl; 23.93% of the patients having CD4(+)T lymphocyte cell counts as <200 cell/µl. 2) 7.26% of the operations were emergent. There were 23 different organs affected at the time of operation, due to 48 different kinds of illness. 21.37% of the operations belonged to class I incision, 49.57% was class II incision and 29.06% was class III incision. 86.32% of the incisions resulted in level A healing, 12.51% resulted in level B and 1.71% in level C. 4.27% of the patients developed post-operative complications. Differences between level A healing and level B or C healing in terms of CD4(+)T lymphocyte cell count were not significant (P > 0.05). There was no statistically significant difference on the CD4(+) T lymphocyte count in patients with or without postoperative complications. Difference of the HIV infection time was also not statistically significant between the two groups of patients. Rate of level A healing for the different CD4(+)T lymphocyte cell count was not significant (P > 0.05). Healing of the incision did not show significant correlation with CD4(+) T lymphocyte cell count, duration of antiretroviral therapy or the time that HIV infection was discovered (P > 0.05). As long as both the in/exclusion criteria were strictly followed, prognosis for operation on HIV/AIDS seemed to be generally good. Low CD4(+)T lymphocyte cell count should not be taken as a exclusion criteria for operation on HIV/AIDS patients.

Extended cervico-thoracic metastasectomy for testicular non-seminomatous germ cell tumour masses through an inverse T and combined collar incision.

Non-seminomatous germ cell tumours (NSGCT) are the most common malignancy from testicular origin in young males. They are characterized by early formation of metastases along retroperitoneal and subsequent mediastinal lymph node stations. Following cisplatin-based induction chemotherapy, residual tumour masses should be removed surgically, although this implies the need for extended procedures. Such an approach can result in cure rates of over 70%. Herein, we report 2 cases of maximally extended surgery for metastatic malignant germ cell tumour of the testis. In both patients, diagnostic work-up revealed a NSGCT with retroperitoneal, mediastinal and cervical lymph node metastases. Multimodal protocols including induction chemotherapy and surgical removal of all primary and secondary tumour masses with curative intent were applied. An 'inverse T' incision in combination with a collar incision was chosen to approach the excessive supra-diaphragmatic tumour spread. This large-scaled surgical access offered an excellent exposure and allowed complete resection of all cervical and thoracic metastases in both patients. Abdominal tumour masses were resected through a standard median laparotomy. These 2 cases illustrate that complete tumour resection is feasible even in stages of NSGCT with generalized lymphatic spread. Metastasectomy should be offered to NSGCT patients despite the necessity of extended surgical approaches. © The Author 2014.

The learning curve for performing living donor hemiliver procurement (LDHP) via small upper midline incision (UMI) has not been determined. Living donors (n=101) who underwent LDHP via UMI were included to investigate the learning curve using cumulative sum analysis. The cumulative sum analysis showed that nine cases for right lobe (case #23) and 19 cases for left lobe (case #32 in the whole series) are needed for stable and acceptable surgical outcomes in LDHP via UMI. The established phase (n=69, since case #33) had a significantly shorter operative time, a smaller incision size, and less blood loss than the previous learning phase (n=32, serial case number up to the last 19th left lobe case). Multivariate analysis showed that the learning phase, high body mass index ≥25 kg/m 2 , and left lobe graft procurement are the factors associated with surgical events including operative blood loss ≥400 mL, operative time ≥300 minutes, or surgical complications ≥Clavien-Dindo grade II. There is an obvious learning curve in performing LDHP via UMI, and 32 cases including both 19 cases for left lobe and nine cases for right lobe are needed for having stable and acceptable surgical outcomes. © 2016 John Wiley & Sons A/S.

Examination of the results and describing the technique of manual small incision extracapsular cataract extraction on patients with advanced cataracts in urban Australia. A descriptive case series. Thirty-eight patients at three public hospitals, one tertiary and two secondary ophthalmic units in urban Australia. Forty eyes with dense mature cataracts with hand movement vision or worse underwent a planned manual small incision extracapsular cataract extraction instead of traditional phaco-emulsification. Postoperative visual aquity, surgically induced astigmatism and complications. Seventy-eight per cent of patients had an uncorrected visual acuity of 6/12 or better on the first postoperative day. Eighty-three per cent of patients had a distance corrected visual acuity of 6/9 or better 3 months postoperatively. One case was complicated by a posterior capsule rupture. No cases of endophthalmitis were reported. The summated vector mean of the surgically induced astigmatism was 0.089D at 93°. Manual small incision extracapsular cataract extraction is an efficacious cataract surgery technique with good visual outcome and is a safe alternative to phaco-emulsification in suitable cases in a first-world setting. © 2014 Royal Australian and New Zealand College of Ophthalmologists.

Single-port access laparoscopic hysterectomy: a new dimension of minimally invasive surgery.

2011-01-01

The fundamental idea is to have all of the laparoscopic working ports entering the abdominal wall through the same incision. Single-incision laparoscopic surgery is an alternative to conventional multiport laparoscopy. Single-access laparoscopy using a transumbilical port affords maximum cosmetic benefits because the surgical incision is hidden in the umbilicus and reduces morbidity of minimally invasive surgery. The advantages of single-access laparoscopic surgery may include less bleeding, infection, and hernia formation and better cosmetic outcome and less pain. The disadvantages and limitations include longer surgery time, difficulty in learning the technique, and the need for specialized instruments. This review summarizes the history of SPAL hysterectomy (single-port access laparoscopy), and emphasizes nomenclature, surgical technique, instrumentation, and perioperative outcomes. Specific gynecological applications of single-port hysterectomy to date are summarized. Using the PubMed database, the English-language literature was reviewed for the past 40 years. Keyword searches included scarless, scar free, single-port/trocar/incision, single-port access laparoscopic hysterectomy. Within the bibliography of selected references, additional sources were retrieved. The purpose of the present article was to review the development and current status of SPAL hysterectomy and highlight important advances associated with this innovative approach.

We describe an original technique for correction of pectus carinatum (PC) through a limited sub-axillary incision by chondrectomy and the use of costal cartilages articulated bars to stabilize the chest wall. We have developed this technique in order to improve the cosmetic results in the surgical treatment of even complex sterno-chondral deformities. The surgical incision is made along the lateral edge of the pectoralis major muscle in the sub-axillary region and its length is related to the number of costal cartilages to be treated. This technique is principally indicated for asymmetric PC with unilateral deformities of the costal cartilages, but its application can be extended to bilateral alteration of the parasternal cartilages by performing the sub-axillary incision bilaterally. When more than four cartilages are removed, the chest is stabilized by articulated bars made using cylindrical fragments obtained by the division of the removed costal cartilages. This thoracoplasty technique performed with a minimally invasive sub-axillary access is simple and safe. It allows the effective treatment of severe PC with either unilateral asymmetric or bilateral costal cartilages deformities, avoiding the median sternal incision and the use of the metallic bar.

Surgical site infection (SSI) remains a persistent and morbid problem in colorectal surgery. Key to its pathogenesis is the degree of intraoperative bacterial contamination at the surgical site. The purpose of this study was to evaluate a novel wound retractor at reducing bacterial contamination. A prospective multicenter pilot study utilizing a novel wound retractor combining continuous irrigation and barrier protection was conducted in patients undergoing elective colorectal resections. Culture swabs were collected from the incision edge prior to device placement and from the exposed and protected incision edge prior to device removal. The primary and secondary endpoints were the rate of enteric and overall bacterial contamination on the exposed incision edge as compared to the protected incision edge, respectively. The safety endpoint was the absence of serious device-related adverse events. A total of 86 patients were eligible for analysis. The novel wound retractor was associated with a 66% reduction in overall bacterial contamination at the protected incision edge compared to the exposed incision edge (11.9 vs. 34.5%, P < 0.001), and 71% reduction in enteric bacterial contamination (9.5% vs. 33.3%, P < 0.001). The incisional SSI rate was 2.3% in the primary analysis and 1.2% in those that completed the protocol. There were no adverse events attributed to device use. A novel wound retractor combining continuous irrigation and barrier protection was associated with a significant reduction in bacterial contamination. Improved methods to counteract wound contamination represent a promising strategy for SSI prevention (NCT 02413879).

The cesarean section was designed to extract to the neoborn, when the childbirth becomes difficult by the natural routes. The institutional obstetrical work demands long surgical time and high raw materials; therefore, simpler procedures must be implemented. To compare traditional cesarean section vs Misgav-Ladach technique to assess surgical time, and hospital stay and costs. Forty-eight pregnant patients at term with obstetrical indication for cesarean delivery were randomized in two groups: 24 were submitted to traditional cesarean and 24 to Misgav-Ladach technique. The outcomes included surgical time, bleeding, amount of sutures employed, pain intensity and some others adverse effects. The surgical time with Misgav-Ladach technique was shorter compared with traditional cesarean section, bleeding was consistently lesser and pain was also low. None adverse effects were registered in both groups. Although short follow-up showed significant operative time reduction and less bleeding, longer follow-up should be desirable in order to confirm no abdominal adhesions.

John Wickham’s New Surgery: ‘Minimally Invasive Therapy’, Innovation, and Approaches to Medical Practice in Twentieth-century Britain

PubMed Central

Frampton, Sally; Kneebone, Roger L.

2017-01-01

Abstract The term ‘minimally invasive’ was coined in 1986 to describe a range of procedures that involved making very small incisions or no incision at all for diseases traditionally treated by open surgery. We examine this major shift in British medical practice as a means of probing the nature of surgical innovation in the twentieth century. We first consider how concerns regarding surgical invasiveness had long been present in surgery, before examining how changing notions of post-operative care formed a foundation for change. We then go on to focus on a professional network involved in the promotion of minimally invasive therapy led by the urologist John Wickham. The minimally invasive movement, we contend, brought into focus tensions between surgical innovation and the evidence-based model of medical practice. Premised upon professional collaborations beyond surgery and a re-positioning of the patient role, we show how the movement elucidated changing notions of surgical authority. PMID:29713119

To demonstrate the utility of robotically assisted approaches in head and neck surgery. Two teenage patients, one with a solitary thyroid nodule who was scheduled for a right thyroid lobectomy and the other with intractable seizures who was scheduled for placement of a vagal nerve stimulator were offered the option of a robotically assisted technique using a transaxillary endoscopic approach. Both procedures were completed successfully using the da Vinci surgical system (Intuitive Surgical, Sunnyvale, California). A 12 mm telescope and 5 mm instruments were used. There was sufficient mobility of the robotic arms despite the small working space. There were no complications, minimal pain in the axillary incisions, and patient satisfaction was high. Operative times were 4.5 and 4.2 hours, respectively. Transaxillary, endoscopic, robotically assisted approaches to the head and neck are feasible. The addition of robotics improves surgical dexterity in a difficult-to-reach anatomic region. Patient satisfaction appears high because of the avoidance of a cervical incision.

Local antimicrobial administration for prophylaxis of surgical site infections.

PubMed

Huiras, Paul; Logan, Jill K; Papadopoulos, Stella; Whitney, Dana

2012-11-01

Despite a lack of consensus guidelines, local antibiotic administration for prophylaxis of surgical site infections is used during many surgical procedures. The rationale behind this practice is to provide high antibiotic concentrations at the site of surgery while minimizing systemic exposure and adverse effects. Local antibiotic administration for surgical site prophylaxis has inherent limitations in that antibiotics are applied after the incision is made, rather than the current standard for surgical site prophylaxis that recommends providing adequate antibiotic concentrations at the site before the incision. The efficacy and safety of local application of antibiotics for surgical site prophylaxis have been assessed in different types of surgery with a variety of antibiotic agents and methods of application. We identified 22 prospective, randomized, controlled trials that evaluated local application of antibiotics for surgical site prophylaxis. These trials were subsequently divided and analyzed based on the type of surgical procedure: dermatologic, orthopedic, abdominal, colorectal, and cardiothoracic. Methods of local application analyzed included irrigations, powders, ointments, pastes, beads, sponges, and fleeces. Overall, there is a significant lack of level I evidence supporting this practice for any of the surgical genres evaluated. In addition, the literature spans several decades, and changes in surgical procedures, systemic antibiotic prophylaxis, and microbial flora make conclusions difficult to determine. Based on available data, the efficacy of local antibiotic administration for the prophylaxis of surgical site infections remains uncertain, and recommendations supporting this practice for surgical site prophylaxis cannot be made. © 2012 Pharmacotherapy Publications, Inc.

This paper presents a novel force modeling for an incision surgery into tissue and its haptic application for a surgeon. During the robot-assisted incision surgery, it is highly urgent to develop the haptic system for realizing sense of touch in the surgical area because surgeons cannot sense sensations. To achieve this goal, the force modeling related to reaction force of biological tissue is proposed in the perspective on energy. The force model describes reaction force focused on the elastic feature of tissue during the incision surgery. Furthermore, the force is realized using calculated information from the model by haptic device using magnetorheological fluid (MRF). The performance of realized force that is controlled by PID controller with open loop control is evaluated.

Increased Hyperalgesia and Proinflammatory Cytokines in the Spinal Cord and Dorsal Root Ganglion After Surgery and/or Fentanyl Administration in Rats

BACKGROUND: Perioperative fentanyl has been reported to induce hyperalgesia and increase postoperative pain. In this study, we tried to investigate behavioral hyperalgesia, the expression of proinflammatory cytokines, such as interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α), and the activation of microglia in the spinal cord and dorsal root ganglion (DRG) in a rat model of surgical plantar incision with or without perioperative fentanyl. METHODS: Four groups of rats (n = 32 for each group) were subcutaneously injected with fentanyl at 60 μg/kg or normal saline for 4 times with 15-minute intervals. Plantar incisions were made to rats in 2 groups after the second drug injection. Mechanical and thermal nociceptive thresholds were assessed by the tail pressure test and paw withdrawal test on the day before, at 1, 2, 3, 4 hours, and on the days 1–7 after drug injection. The lumbar spinal cord, bilateral DRG, and cerebrospinal fluid of 4 rats in each group were collected to measure IL-1β, IL-6, and TNF-α on the day before, at the fourth hour, and on the days 1, 3, 5, and 7 after drug injection. The lumbar spinal cord and bilateral DRG were removed to detect the ionized calcium-binding adapter molecule 1 on the day before and on the days 1 and 7 after drug injection. RESULTS: Rats injected with normal saline only demonstrated no significant mechanical or thermal hyperalgesia or any increases of IL-1β, IL-6, and TNF-α in the spinal cord or DRG. However, injection of fentanyl induced analgesia within as early as 4 hours and a significant delayed tail mechanical and bilateral plantar thermal hyperalgesia after injections lasting for 2 days, while surgical plantar incision induced a significant mechanical and thermal hyperalgesia lasting for 1–4 days. The combination of fentanyl and incision further aggravated the hyperalgesia and prolonged the duration of hyperalgesia. The fentanyl or surgical incision upregulated the expression of IL-1β, IL-6, and TNF-α in the spinal cord and bilateral DRG for more than 7 days and increase of ionized calcium-binding adapter molecule 1 in the spinal cord. The combination of fentanyl and incision resulted in higher increase of IL-1β, IL-6, and TNF-α in the spinal cord and bilateral DRG. CONCLUSIONS: The surgical plantar incision with or without perioperative fentanyl induced significant mechanical and thermal hyperalgesia, an increased expression of IL-1β, IL-6, TNF-α in the spinal cord and DRG, and activation of microglia in the spinal cord.

Use of electrosurgery for skin incisions has been controversial due to concerns of delayed healing, excessive scarring, and increased infection. Recent studies using modern electrosurgical generators that produce pure sinusoidal "CUT" waveforms have shown reductions in thermal damage along incisions made with these devices compared with their predecessors. This study compares scar formation in incisions made using a cold steel scalpel (CSS) or the ACE Blade and Mega Power Generator (ACE system, Megadyne Medical Products, Draper, Utah) from patient and blinded observer perspectives. Subjects seeking plastic surgery were enrolled in the study. Incisions on one side of each subject's body were made with a CSS while equivalent incisions on the contralateral side were made with the ACE system. Differences between incision methods were evaluated by assessment of scar formation by observers and assessment of patient satisfaction relating to scar formation at 120 days postsurgery. Observers rated incision vascularization, pigmentation, thickness, and relief. The mean observer score (± SD) of incisions made with the ACE system was 11.1 ± 4.4 while that of incisions made with the CSS was 10.8 ± 3.7 (P < 0.0001). Patients rated incision pain, itching, discoloration, stiffness, thickness, and irregularity. The mean patient score of incisions made with the ACE system was 9.4 ± 9.2 while that of incisions made with the CSS was 9.3 ± 8.5 (P < 0.0001). Results showed noninferior wound healing/scar formation in skin incisions made with the ACE system compared with incisions made with a CSS.

The purpose of the present study is a systematic review of previous studies on choosing the best incision site for the correction of astigmatism in cataract surgery and assessing the amount of surgically induced astigmatism (SIA) with each approach. Regardless of astigmatism axis, studies show that using an on-axis incision is associated with favorable results for 0.5-1.0 diopter (D) of astigmatism. In cases with more than 1.0 D astigmatism, paired on-axis incisions can be appreciably efficient in astigmatism correction and cause at least 1.5 D SIA. Considering the amount of SIA, a temporal incision is the best approach when the patient has minimal amounts of corneal astigmatism preoperatively. At higher levels of astigmatism, if no other astigmatism correction method is used simultaneously, the temporal incision is used less frequently; however, since it is associated with the least SIA, it is still the choice site when another correction method is used. The temporal incisions in cataract surgery are associated with little SIA and are appropriate choices for mild preoperative astigmatism. At higher levels of preoperative astigmatism, superior incisions are associated with better results when combined methods are not applied.

In this case report, we discuss single-incision laparoscopic cecectomy for low-grade appendiceal neoplasm after laparoscopic anterior resection for rectal cancer. The optimal surgical therapy for low-grade appendiceal neoplasm is controversial; currently, the options include appendectomy, cecectomy, right hemicolectomy, and open or laparoscopic surgery. Due to the risk of pseudomyxoma peritonei, complete resection without rupture is necessary. We have encountered 5 cases of low-grade appendiceal neoplasm and all 5 patients had no lymph node metastasis. We chose the appendectomy or cecectomy without lymph node dissection if preoperative imaging studies did not suspect malignancy. In the present case, we performed cecectomy without lymph node dissection by single-incision laparoscopic surgery (SILS), which is reported to be a reduced port surgery associated with decreased invasiveness and patient stress compared with conventional laparoscopic surgery. We are confident that SILS is a feasible alternative to traditional surgical procedures for borderline tumors, such as low-grade appendiceal neoplasms. PMID:24868331

Iatrogenic injury to the infrapatellar branch of the saphenous nerve is a common complication of surgical approaches to the anteromedial side of the knee. A detailed description of the relative anatomic course of the nerve is important to define clinical guidelines and minimize iatrogenic damage during anterior knee surgery. In twenty embalmed knees, the infrapatellar branch of the saphenous nerve was dissected. With use of a computer-assisted surgical anatomy mapping tool, safe and risk zones, as well as the location-dependent direction of the nerve, were calculated. The location of the infrapatellar branch of the saphenous nerve is highly variable, and no definite safe zone could be identified. The infrapatellar branch runs in neither a purely horizontal nor a vertical course. The course of the branch is location-dependent. Medially, it runs a nearly vertical course; medial to the patellar tendon, it has a -45° distal-lateral course; and on the patella and patellar tendon, it runs a close to horizontal-lateral course. Three low risk zones for iatrogenic nerve injury were identified: one is on the medial side of the knee, at the level of the tibial tuberosity, where a -45° oblique incision is least prone to damage the nerves, and two zones are located medial to the patellar apex (cranial and caudal), where close to horizontal incisions are least prone to damage the nerves. The infrapatellar branch of the saphenous nerve is at risk for iatrogenic damage in anteromedial knee surgery, especially when longitudinal incisions are made. There are three low risk zones for a safer anterior approach to the knee. The direction of the infrapatellar branch of the saphenous nerve is location-dependent. To minimize iatrogenic damage to the nerve, the direction of incisions should be parallel to the direction of the nerve when technically possible. These findings suggest that iatrogenic damage of the infrapatellar branch of the saphenous nerve can be minimized in anteromedial knee surgery when both the location and the location-dependent direction of the nerve are considered when making the skin incision.

The aim of this study was to review the typical factors related to physician's liability in obstetrics and gynecology departments, as compared to those in internal medicine and surgery, regarding a breach of the duty to explain. This study involved analyzing 366 medical litigation case reports from 1990 through 2008 where the duty to explain was disputed. We examined relationships between patients, physicians, variables related to physician's explanations, and physician's breach of the duty to explain by comparing mean values and percentages in obstetrics and gynecology, internal medicine, and surgical departments with the t-test and χ(2) test. When we compared the reasons for decisions in cases where the patient won, we found that the percentage of cases in which the patient's claim was recognized was the highest for both physician negligence, including errors of judgment and procedural mistakes, and breach of the duty to explain, in obstetrics and gynecology departments; breach of the duty to explain alone in internal medicine departments; and mistakes in medical procedures alone in surgical departments (p = 0.008). When comparing patients, the rate of death was significantly higher than that of other outcomes in precedents where a breach of the duty to explain was acknowledged (p = 0.046). The proportion of cases involving obstetrics and gynecology departments, in which care was claimed to be substandard at the time of treatment, and that were not argued as breach of a duty to explain, was significantly higher than those of other evaluated departments (p <0.001). However, internal medicine and surgical departments were very similar in this context. In obstetrics and gynecology departments, the proportion of cases in which it had been conceded that the duty to explain had been breached when seeking patient approval (or not) was significantly higher than in other departments (p = 0.002). It is important for physicians working in obstetrics and gynecology departments to carefully explain the risk of death associated with any planned procedure, and to obtain genuinely informed patient consent.

Povidone-iodine induced post-surgical irritant contact dermatitis localized outside of the surgical incision area. Report of 27 cases and a literature review.

Povidone-iodine solution is an antiseptic that is used worldwide as surgical paint and is considered to have a low irritant potential. Post-surgical severe irritant dermatitis has been described after the misuse of this antiseptic in the surgical setting. Between January 2011 and June 2013, 27 consecutive patients with post-surgical contact dermatitis localized outside of the surgical incision area were evaluated. Thirteen patients were also available for patch testing. All patients developed dermatitis the day after the surgical procedure. Povidone-iodine solution was the only liquid in contact with the skin of our patients. Most typical lesions were distributed in a double lumbar parallel pattern, but they were also found in a random pattern or in areas where a protective pad or an occlusive medical device was glued to the skin. The patch test results with povidone-iodine were negative. Povidone-iodine-induced post-surgical dermatitis may be a severe complication after prolonged surgical procedures. As stated in the literature and based on the observation that povidone-iodine-induced contact irritant dermatitis occurred in areas of pooling or occlusion, we speculate that povidone-iodine together with occlusion were the causes of the dermatitis epidemic that occurred in our surgical setting. Povidone-iodine dermatitis is a problem that is easily preventable through the implementation of minimal routine changes to adequately dry the solution in contact with the skin. © 2015 The International Society of Dermatology.

Voice tuning with new instruments for type II thyroplasty in the treatment of adductor spasmodic dysphonia.

Adductor spasmodic dysphonia is a rare voice disorder characterized by strained and strangled voice quality with intermittent phonatory breaks and adductory vocal fold spasms. Type II thyroplasty differs from previous treatments in that this surgery does not involve any surgical intervention into the laryngeal muscle, nerve or vocal folds. Type II thyroplasty intervenes in the thyroid cartilage, which is unrelated to the lesion. This procedure, conducted with the aim of achieving lateralization of the vocal folds, requires utmost surgical caution due to the extreme delicacy of the surgical site, critically sensitive adjustment, and difficult procedures to maintain the incised cartilages at a correct position. During surgery, the correct separation of the incised cartilage edges with voice monitoring is the most important factor determining surgical success and patient satisfaction. We designed new surgical instruments: a thyroid cartilage elevator for undermining the thyroid cartilage, and spacer devices to gauge width while performing voice monitoring. These devices were designed to prevent surgical complications, and to aid in selecting the optimal size of titanium bridges while temporally maintaining a separation during voice monitoring. We designed new surgical instruments, including a thyroid cartilage elevator and spacer devices. Precise surgical procedures and performing voice tuning during surgery with the optimal separation width of the thyroid cartilage are key points for surgical success. We introduce the technique of voice tuning using these surgical tools in order to achieve a better outcome with minimal surgical complications. Copyright © 2016 Elsevier Ireland Ltd.

Surgical trauma produces metabolic and hormonal responses, which are characterized by insulin resistance. Due to extension of the preoperative fasting period, which increases the magnitude of postoperative insulin resistance, preoperative oral carbohydrates (POC) have been developed. This prospective, randomized, controlled study was performed on 43 ASA I-II patients undergoing elective microsurgical lumbar discectomy. The intervention group received oral carbohydrate solution 800mL the night before and 400mL 2h prior to operation. The other group fasted for 8h prior to operation. Blood samples were obtained the day before the operation, before induction of anesthesia, after skin incision, 1h, 2h, 6h and 24h following skin incision. Blood glucose, plasma insulin, cortisol and interleukin-6 (IL-6) levels were determined. The primary endpoint was to assess the effect of POC treatment on insulin resistance and surgical stress response following lumbar disc surgery. The secondary endpoint was to assess POC's effects on postoperative nausea and vomiting. The serum insulin levels were higher before induction of anesthesia in the study group and returned to fasted group levels by 2h after skin incision. The plasma IL-6 levels were higher in the intervention group at 6h after the skin incision. There were no differences between the two groups with respect to blood glucose, plasma cortisol levels and the incidence of nausea and vomiting. This study suggests that use of POC treatment does not attenuate development of insulin resistance in patients undergoing lumbar disc surgery. Copyright © 2016. Published by Elsevier B.V.

Treatment of Mandibular Condyle Fractures Using a Modified Transparotid Approach via the Parotid Mini-Incision: Experience with 31 Cases

PubMed Central

2013-01-01

Surgery for mandibular condyle fractures must allow direct vision of the fracture, reduce surgical trauma and achieve reduction and fixation while avoiding facial nerve injury. This prospective study was conducted to introduce a new surgical approach for open reduction and internal fixation of mandibular condyle fractures using a modified transparotid approach via the parotid mini-incision, and surgical outcomes were evaluated. The modified transparotid approach via the parotid mini-incision was applied and rigid internal fixation using a small titanium plate was carried out for 36 mandibular condyle fractures in 31 cases. Postoperative follow-up of patients ranged from 3 to 26 months; in the first 3 months after surgery, outcomes for all patients were analyzed by evaluating the degree of mouth opening, occlusal relationship, facial nerve function and results of imaging studies. The occlusal relationships were excellent in all patients and none had symptoms of intraoperative ipsilateral facial nerve injury. The mean degree of mouth opening was 4.0 (maximum 4.8 cm, minimum 3.0 cm). No mandibular deviations were noted in any patient during mouth opening. CT showed complete anatomical reduction of the mandibular condyle fracture in all patients. The modified transparotid approach via the smaller, easily concealed parotid mini-incision is minimally invasive and achieves anatomical reduction and rigid internal fixation with a simplified procedure that directly exposes the fracture site. Study results showed that this procedure is safe and feasible for treating mandibular condyle fracture, and offers a short operative path, protection of the facial nerve and satisfactory aesthetic outcomes.

Recent studies and anecdotal evidence suggest that patient safety may be compromised on weekends. Our objective was to determine whether rates of complications in hospitals are higher on weekends than on weekdays. We examined records from 4,967,114 admissions to acute care hospitals in 3 states and analyzed complication rates using the Patient Safety Indicators. We selected 8 indicators that could be assigned to a single day: complications of anesthesia, retained foreign bodies, postoperative hemorrhage, accidental cuts and lacerations during procedures, birth trauma, obstetric trauma during vaginal deliveries with and without instrumentation, and obstetric trauma during cesarean delivery. Odds ratios (ORs) comparing weekends versus weekdays were adjusted for demographics, type of admission, and admission route. In a subgroup analysis of surgical complications, we restricted the population to patients who underwent cardiac or vascular procedures. Four of the 8 complications occurred more frequently on weekends: postoperative hemorrhage (OR 1.07, 95% confidence interval [CI], 1.01-1.14), newborn trauma (OR 1.06, 95% CI, 1.03-1.10), vaginal deliveries without instrumentation (OR 1.03, 95% CI, 1.02-1.04), and obstetric trauma during cesarean sections (OR 1.36, 95% CI, 1.29-1.44). Complications related to anesthesia occurred less frequently on weekends (OR 0.86). Among patients undergoing vascular procedures, surgical complications occurred more frequently on weekends (OR 1.46, 95% CI, 1.16-1.85). Rates of complications are marginally higher on weekends than on weekdays for some surgical and newborn complications, but more significantly for obstetric trauma and for surgical complications involving patients undergoing vascular procedures. Hospitals should work toward increasing the robustness of safeguards on weekends.

Misgav-Ladach cesarean section: general consideration.

Fatusić, Zlatan; Hudić, Igor; Musić, Asim

Among obstetric techniques, cesarean section seemed to represent a well-defined procedure and significant advances in this intervention were considered to be unlikely. However, obstetric surgery has recently undergone many improvements. In 1972, Joel-Cohen presented a new method for transverse incision of the abdomen. This method, with some modifications, was integrated into the Misgav-Ladach cesarean section. The philosophy of this technique is to cause the least possible damage to tissues, to refrain from superfluous steps, and to make the intervention the simplest possible. Advantages of this method are lower incidence of fever and urinary tract infection, reduced use of antibiotics and narcotics, faster re-establishment of normal bowel function, shorter maternal hospital stay and less postoperative adhesion formation. The Misgav-Ladach method of cesarean section is suitable for emergency and elective procedures, justifying its use in daily routine.

To survey infrastructure characteristics, personnel, equipment and procedures of surgical, obstetric and anaesthesia care in 17 hospitals in Ghana. The assessment was completed by WHO country offices using the World Health Organization Tool for Situational Analysis to Assess Emergency and Essential Surgical Care, which surveyed infrastructure, human resources, types of surgical interventions and equipment in each facility. Overall, hospitals were well equipped with general patient care and surgical supplies. The majority of hospitals had a basic laboratory (100%), running water (94%) and electricity (82%). More than 75% had the basic supplies needed for general patient care and basic intra-operative care, including sterilization. Almost all hospitals were able to perform major surgical procedures such as caesarean sections (88%), herniorrhaphy (100%) and appendectomy (94%), but formal training of providers was limited: a few hospitals had a fully qualified surgeon (29%) or obstetrician (36%) available. The greatest barrier to improving surgical care at district hospitals in Ghana is the shortage of adequately trained medical personnel for emergency and essential surgical procedures. Important future steps include strengthening their number and qualifications. © 2010 Blackwell Publishing Ltd.

2016-01-01

Cesarean delivery (CD) is one of the most common major surgeries performed in the United States and worldwide. Surgical techniques evaluated in well-designed randomized controlled trials (RCTs) that demonstrate maternal benefit should be incorporated into practice. The objective of this review is to provide a summary of surgical techniques of the procedure and review the evidence basis for them for the nonobstetrician. The following techniques with the strongest evidence should be commonly performed, when feasible: (1) prophylactic antibiotics with a single dose of ampicillin or first-generation cephalosporin prior to skin incision; (2) postpartum hemorrhage prevention with oxytocin infusion of 10 to 40 IU in 1 L crystalloid over 4 to 8 hours; (3) low transverse skin incision; (4) blunt or sharp subcutaneous and fascial expansion; (5) blunt, cephalad–caudad uterine incision expansion; (6) spontaneous placental removal; (7) blunt-tip needle usage during closure; (8) subcutaneous suture closure (running or interrupted) if thickness is ≥2 cm; and (9) skin closure with suture. Although the number of RCTs designed to optimize maternal and neonatal outcomes of this common procedure is encouraging, further work is needed to minimize surgical morbidity. Optimal methods for postpartum hemorrhage prevention, adhesion prevention, and venous thromboembolism prophylaxis remain ongoing areas of active research, with outcomes that could markedly improve maternal morbidity and mortality. If evidence of a surgical technique appears preferred over another, clinicians should be comfortable adopting the evidence-based technique when performing and teaching CD. PMID:28824974

Dressing wear time after breast reconstruction: study protocol for a randomized controlled trial

PubMed Central

2013-01-01

Background One of the major risk variables for surgical site infection is wound management. Understanding infection risk factors for breast operations is essential in order to develop infection-prevention strategies and improve surgical outcomes. The aim of this trial is to assess the influence of dressing wear time on surgical site infection rates and skin colonization. Patients’ perception at self-assessment will also be analyzed. Methods/Design This is a two-arm randomized controlled trial. Two hundred breast cancer patients undergoing immediate or delayed breast reconstruction will be prospectively enrolled. Patients will be randomly allocated to group I (dressing removed on postoperative day one) or group II (dressing removed on postoperative day six). Surgical site infections will be defined by standard criteria from the Centers for Disease Control and Prevention (CDC). Skin colonization will be assessed by culture of samples collected at predefined time points. Patients will score dressing wear time with regard to safety, comfort and convenience. Discussion The evidence to support dressing standards for breast surgery wounds is empiric and scarce. CDC recommends protecting, with a sterile dressing for 24 to 48 hours postoperatively, a primarily closed incision, but there is no recommendation to cover this kind of incision beyond 48 hours, or on the appropriate time to shower or bathe with an uncovered incision. The results of the ongoing trial may support standard recommendations regarding dressing wear time after breast reconstruction. Trial registration ClinicalTrials.gov identifier: http://NCT01148823.

Microincision, aspiration cutter-assisted multifocal iris biopsy for melanoma.

PubMed

Finger, Paul T; Milman, Tatyana

2017-01-19

To describe a minimally invasive method to create multifocal full-thickness surgical iridectomy biopsies. Seven patients suspected to have diffuse iris melanoma underwent multifocal surgical iridectomy biopsy through a single 1.0-mm clear corneal incision. A 25-G inked trocar was used to create one visible corneal portal, through which the anterior chamber was filled with sodium hyaluronate 1%. Then, a 25-G aspiration cutter probe was introduced through the corneal incision such that the aspiration portal was occluded by the iris biopsy sites. Then aspiration (600 mm Hg) cutting (300 cuts per minute) was used to create full- and partial-thickness surgical iridectomy biopsies at multiple locations. After each biopsy the probe was removed, and its contents aspirated into a separate 3-mL syringe (marked by clock hour location). The sodium hyaluronate 1% was removed and wound checked for leakage. Diagnostic specimens were obtained in all cases. Five were found to be diffuse iris melanomas and 2 were indeterminate iris melanocytic proliferations. No patients developed a secondary increase in intraocular pressure, hyphema, infection, cataract, or vision loss. No cases of intraocular tumor dissemination were observed. No patient complained of glare or monocular diplopia. Three of 7 corneal wounds were self-sealing. Multifocal surgical iridectomy biopsy can be minimally invasive and effective allowing for partial- and full-thickness iris biopsy. Use of a 25-G aspiration cutting probe allowed for small incision surgery, rapid rehabilitation, and no significant complications.

Women's preference of cosmetic results after gynecologic surgery.

To determine the cosmetic appeal of different incision types used in gynecologic surgery. One hundred women between the ages of 20 and 40 years were shown 4 color photographs of a female abdomen with incision sites marked for Pfannenstiel, minilaparotomy, traditional laparoscopy, and robotic-assisted laparoscopy. The women were asked to rank the photographs on cosmetic appeal alone. An additional photograph depicting single-port laparoscopy was then added, and patients were asked to again rank the photographs. Participants were also asked basic demographic information and prior surgical history. Office practice. One hundred women between the ages of 20 and 40. Participants. Minilaparotomy was ranked as the most appealing incision among the first set of photographs by 74% of the participants, and the remaining 26% preferred traditional laparoscopy. Robotic-assisted laparoscopy was ranked as the least appealing scar type by 42%, and no patient selected it as their first choice. Sixty-four percent preferred the appearance of a single-port laparoscopic scar when that option was added. The only demographic variable that reached statistical significance was the presence of prior abdominal surgery. Patients without prior surgery ranked minilaparotomy as more cosmetically appealing. When several minimally invasive surgical approaches are possible, the patient should be counseled regarding the cosmetic results of each. Patients in this study strongly preferred the appearance of minilaparotomy and single-port incisions over full Pfannenstiel or robotic incisions. Copyright © 2014 AAGL. Published by Elsevier Inc.

The aim of this study was to review and evaluate the selection and dose of anesthetic agents and the interval from the block procedure to skin incision for supraclavicular brachial plexus block in upper extremity surgery. We reviewed our cases that underwent upper extremity surgery using only ultrasound-guided supraclavicular brachial plexus block in our hospital between 2011 and 2016. Adverse events during surgery were evaluated. Receiver operating characteristic (ROC) curves were constructed to investigate the relationship between the time from the end of the block procedure to skin incision and the use of local anesthesia on the surgical site. There were 255 patients who were divided into three groups according to the anesthetic agents used: group 1, 1% lidocaine (L) 10 ml + 0.75% ropivacaine (R) 20 ml (n = 62); group 2, L 20 ml + R 10 ml (n = 93); and group 3, L 10 ml + R 15 ml (n = 100). The rate of use of local anesthesia on the surgical site was significantly higher in group 3 than in the other two groups. There were no significant differences in the other evaluated items among the three groups. ROC curve analysis indicated that ≥24 min from the end of the block procedure to skin incision might reduce the use of local anesthesia. The total volume of anesthetic agents had an important influence on the rate of the addition of local anesthesia for surgical pain; however, the combined dose of agents did not influence the evaluation items. For effective analgesia, ≥24 min should elapse from the end of the block procedure to skin incision. Copyright © 2017. Published by Elsevier B.V.

This work is a topic highlight on the surgical treatment of the right colon pathologies, focusing on the literature state of art and comparing the open surgery to the different laparoscopic and robotic procedures. Different laparoscopic procedures have been described for the treatment of right colon tumors: Totally laparoscopic right colectomy, laparoscopic assisted right colectomy, laparoscopic facilitated right colectomy, hand-assisted right colectomy, single incision laparoscopic surgery colectomy, robotic right colectomy. Two main characteristics of these techniques are the different type of anastomosis: Intracorporeal (for totally laparoscopic right colectomy, single incision laparoscopic surgery colectomy, laparoscopic assisted right colectomy and robotic technique) or extracorporeal (for laparoscopic assisted right colectomy, laparoscopic facilitated right colectomy, hand-assisted right colectomy and open right colectomy) and the different incision (suprapubic, median or transverse on the right side of abdomen). The different laparoscopic techniques meet the same oncological criteria of radicalism as the open surgery for the right colon. The totally laparoscopic right colectomy with intracorporeal anastomosis and even more the single incision laparoscopic surgery colectomy, remain a technical challenge due to the complexity of procedures (especially for the single incision laparoscopic surgery colectomy) and the particular right colon vascular anatomy but they seem to have some theoretical advantages compared to the other laparoscopic and open procedures. Data reported in literature while confirming the advantages of laparoscopic approach, do not allow to solve controversies about which is the best laparoscopic technique (Intracorporeal vs Extracorporeal Anastomosis) to treat the right colon cancer. However, the laparoscopic techniques with intracorporeal anastomosis for the right colon seem to show some theoretical advantages (functional, technical, oncological and cosmetic advantages) even if all studies conclude that further prospective randomized trials are necessary. Robotic technique may be useful to overcome the problems related to inexperience in laparoscopy in some surgical centers. PMID:27648160

A preliminary study of the effect of closed incision management with negative pressure wound therapy over high-risk incisions.

Certain postoperative wounds are recognised to be associated with more complications than others and may be termed high-risk. Wound healing can be particularly challenging following high-energy trauma where wound necrosis and infection rates are high. Surgical incision for joint arthrodesis can also be considered high-risk as it requires extensive and invasive surgery and postoperative distal limb swelling and wound dehiscence are common. Recent human literature has investigated the use of negative pressure wound therapy (NPWT) over high-risk closed surgical incisions and beneficial effects have been noted including decreased drainage, decreased dehiscence and decreased infection rates. In a randomised, controlled study twenty cases undergoing distal limb high-energy fracture stabilisation or arthrodesis were randomised to NPWT or control groups. All cases had a modified Robert-Jones dressing applied for 72 h postoperatively and NPWT was applied for 24 h in the NPWT group. Morphometric assessment of limb circumference was performed at six sites preoperatively, 24 and 72 h postoperatively. Wound discharge was assessed at 24 and 72 h. Postoperative analgesia protocol was standardised and a Glasgow Composite Measure Pain Score (GCPS) carried out at 24, 48 and 72 h. Complications were noted and differences between groups were assessed. Percentage change in limb circumference between preoperative and 24 and 72 h postoperative measurements was significantly less at all sites for the NPWT group with exception of the joint proximal to the surgical site and the centre of the operated bone at 72 h. Median discharge score was lower in the NPWT group than the control group at 24 h. No significant differences in GCPS or complication rates were noted. Digital swelling and wound discharge were reduced when NPWT was employed for closed incision management. Larger studies are required to evaluate whether this will result in reduced discomfort and complication rates postoperatively.

To report an autograft of ovarian tissue in the incision of the surgical trocar during laparoscopic surgery and to assess the potentiality of grafting of ovarian parenchyma in nonpelvic tissue in humans. A case report. Instituto de Fertilidad y Ginecología de Buenos Aires (IFER), Buenos Aires, Argentina. Infertile patient undergoing surgery due to an endometriotic cyst of the left ovary. Laparoscopic cystectomy. Accidental retention of a portion of the capsule and adjacent ovarian tissue of the endometrioma in SC cellular tissue. Months after surgery, a SC tumor was formed under the surgical incision. It was subsequently excised. Observation of tumor growth during menstrual cycles and ovulation induction; anatomopathologic study of the tissue after its extirpation. The tumor grew spontaneously in the periovulatory period and during treatments of ovulation induction. The anatomopathologic report of the tumor, removed 15 months after the first surgery, revealed functioning ovarian tissue with vessels of neoformation. This is the first description of autografted ovarian tissue in humans. We describe that the ovary can maintain its ovulatory function even in the absence of its pedicel. Also, we suggest that extirpation of surgical material through the incision of the trocar is not recommended, as the possibility of "sowing" or of autografts may occur.

Objective: Robotic assistance during surgery has been shown to be a useful resource to both augment the surgical skills of the surgeon through tele-operation, and to assist the surgeon handling the surgical instruments to the surgeon, similar to a surgical tech. We evaluated the performance and effect of a gesture driven surgical robotic nurse in the context of economy of movements, during an abdominal incision and closure exercise with a simulator. Methods: A longitudinal midline incision (100 mm) was performed on the simulated abdominal wall to enter the peritoneal cavity without damaging the internal organs. The wound was then closed using a blunt needle ensuring that no tissue is caught up by the suture material. All the instruments required to complete this task were delivered by a robotic surgical manipulator directly to the surgeon. The instruments were requested through voice and gesture recognition. The robotic system used a low end range sensor camera to extract the hand poses and for recognizing the gestures. The instruments were delivered to the vicinity of the patient, at chest height and at a reachable distance to the surgeon. Task performance measures for each of three abdominal incision and closure exercises were measured and compared to a human scrub nurse instrument delivery action. Picking instrument position variance, completion time and trajectory of the hand were recorded for further analysis. Results: The variance of the position of the robotic tip when delivering the surgical instrument is compared to the same position when a human delivers the instrument. The variance was found to be 88.86% smaller compared to the human delivery group. The mean task completion time to complete the surgical exercise was 162.7+/- 10.1 secs for the human assistant and 191.6+/- 3.3 secs (P<.01) when using the robotic standard display group. Conclusion: Multimodal robotic scrub nurse assistant improves the surgical procedure by reducing the number of movements (lower variance in the picking position). The variance of the picking point is closely related to the concept of economy of movements in the operating room. Improving the effectiveness of the operating room can potentially enhance the safety of surgical interventions without affecting the performance time.

This study aimed to demonstrate the effectiveness of using a multifunctional miniature in vivo robotic platform to perform a single-incision colectomy. Standard laparoscopic techniques require multiple ports. A miniature robotic platform to be inserted completely into the peritoneal cavity through a single incision has been designed and built. The robot can be quickly repositioned, thus enabling multiquadrant access to the abdominal cavity. The miniature in vivo robotic platform used in this study consists of a multifunctional robot and a remote surgeon interface. The robot is composed of two arms with shoulder and elbow joints. Each forearm is equipped with specialized interchangeable end effectors (i.e., graspers and monopolar electrocautery). Five robotic colectomies were performed in a porcine model. For each procedure, the robot was completely inserted into the peritoneal cavity, and the surgeon manipulated the user interface to control the robot to perform the colectomy. The robot mobilized the colon from its lateral retroperitoneal attachments and assisted in the placement of a standard stapler to transect the sigmoid colon. This objective was completed for all five colectomies without any complications. The adoption of both laparoscopic and single-incision colectomies currently is constrained by the inadequacies of existing instruments. The described multifunctional robot provides a platform that overcomes existing limitations by operating completely within one incision in the peritoneal cavity and by improving visualization and dexterity. By repositioning the small robot to the area of the colon to be mobilized, the ability of the surgeon to perform complex surgical tasks is improved. Furthermore, the success of the robot in performing a completely in vivo colectomy suggests the feasibility of using this robotic platform to perform other complex surgeries through a single incision.

To compare the surgically induced astigmatism (SIA) vector, flattening effect, torque, and wound architecture following femtosecond laser and manual clear corneal incisions (CCIs). In a double-armed, randomized, prospective case series, cataract surgery was performed for 600 eyes using femtosecond laser (300 eyes) or manual (300 eyes) 2.4-mm CCIs in temporal or superior oblique locations. SIA, flattening effect, torque, and the summated vector mean for SIA were calculated. Correlation with individual features was established and incision morphology was investigated by anterior segment optical coherence tomography at 3 months of follow-up. The SIA, flattening effect, and torque were lower in the femtosecond laser group for both incision locations, although the differences were not significant (all P > .05). The femtosecond laser group showed less dispersion of SIA magnitude and flattening effect. Temporal and superior oblique incisions resulted in flattening effect values of -0.11 and -0.21 diopters (D), respectively, in the femtosecond laser group and -0.13 and -0.34 D, respectively, in the manual group. Significant correlations with individual features were only found in the femtosecond laser group, with preoperative astigmatism being the only significant SIA predictor by multiple regression analysis (P = .003). Femtosecond laser CCIs showed less deviation from the intended length, wound enlargement, endothelial misalignment, and Descemet membrane detachments (all P < .037). Femtosecond laser CCIs were more reproducible. Although SIAs were smaller in femtosecond laser CCIs than in manual CCIs for both temporal and superior oblique incisions, the difference was not statistically significant. Association with individual features is highly variable. [J Refract Surg. 2018;34(5):322-329.]. Copyright 2018, SLACK Incorporated.

The 3-piece inflatable penile prosthesis (IPP) is the gold standard treatment for male erectile dysfunction when other less invasive approaches are contra-indicated or unacceptable for the patient. There are currently 2 surgical approaches for IPP implantation: the penoscrotal (PS) and the infrapubic (IP) incision. To assess the most recent evidence on the impact of surgical approach for 3-piece IPP implantation in patients with erectile dysfunction. A systematic literature review was performed using the MEDLINE (PubMed) and Cochrane Libraries databases in November 2017 to identify all studies investigating 3-piece IPP with a specified surgical access. The following key words were used in combination: "infrapubic," "transcrotal," "penoscrotal," "peno-scrotal," and "penile prosthesis." Additional references were obtained from the reference lists of full-text manuscripts. We used a narrative synthesis for the analyses of the studies. 22 Studies reporting data on 3-piece IPP implantation with a specified surgical approach were found in the literature. While IPPs are most commonly positioned through a PS incision, the IP approach is a faster procedure. No cases of glans hypoesthesia after IPP placement with an IP approach were reported, and the overall peri-prosthetic infection rate was 3.3% or less. Patient satisfaction rates were higher than 80% in both groups. Both the IP and PS approaches are viable and effective strategies for a 3-piece IPP placement, and result in high satisfaction rates. To date there is no evidence that an incision strategy may reduce infection rates. Penile sensory loss following an IP approach remains a virtual risk. It is recommended that the surgeon executing the implant have knowledge of both accesses and be capable of tailoring the incision strategy for complex cases. The chosen method should be based on the patient's specific anatomy, surgical history, and surgeon experience. Palmisano F, Boeri L, Cristini C, et al.

Surgical Informed Consent (SIC) has long been recognized as an important component of modern medicine. The ultimate goals of SIC are to improve clients' understanding of the intended procedure, increase client satisfaction, maintain trust between clients and health providers, and ultimately minimize litigation issues related to surgical procedures. The purpose of the current study is to assess the comprehensiveness of the SIC process for women undergoing obstetric and gynecologic surgeries. A hospital-based cross-sectional study was undertaken at Hawassa University Comprehensive Specialized Hospital (HUCSH) in November and December, 2016. A total of 230 women who underwent obstetric and/or gynecologic surgeries were interviewed immediately after their hospital discharge to assess their experience of the SIC process. Thirteen components of SIC were used based on international recommendations, including the Royal College of Surgeon's standards of informed consent practices for surgical procedures. Descriptive summaries are presented in tables and figures. Forty percent of respondents were aged between 25 and 29 years. Nearly a quarter (22.6%) had no formal education. More than half (54.3%) of respondents had undergone an emergency surgical procedure. Only 18.4% of respondents reported that the surgeon performing the operation had offered SIC, while 36.6% of respondents could not recall who had offered SIC. All except one respondent provided written consent to undergo a surgical procedure. However, 8.3% of respondents received SIC service while already on the operation table for their procedure. Only 73.9% of respondents were informed about the availability (or lack thereof) of alternative treatment options. Additionally, a majority of respondents were not informed about the type of anesthesia to be used (88.3%) and related complications (87.4%). Only 54.2% of respondents reported that they had been offered at least six of the 13 SIC components used by the investigators. There is gap in the provision of comprehensive and standardized pre-operative counseling for obstetric and gynecologic surgeries in the study hospital. This has a detrimental effect on the overall quality of care clients receive, specifically in terms of client expectations and information needs.

We compared the primary metrics of the Spectral entropy M-ENTROPY™ module and BIS VISTA™ monitor-i.e., bispectral index (BIS), state entropy (SE), and response entropy (RE) in terms of agreement and correlation during general anesthesia for cardiac surgery. We also evaluated responsiveness of electroencephalogram (EEG)-based and hemodynamic parameters to surgical noxious stimulation, skin incision, and sternotomy, hypothesizing that RE would be a better responsiveness predictor. BIS and entropy sensors were applied before anesthesia induction in 32 patients having elective cardiac surgery. Total intravenous anesthesia was standardized and guided by the BIS index with neuromuscular blockade tested with train-of-four monitoring. Parameters included SE, RE, BIS, forehead electromyography (EMG), and hemodynamic variables. Time points for analyzing BIS, entropy, and hemodynamic values were 1 min before and after: anesthesia induction, intubation, skin incision, sternotomy, cannulation of the aorta, cardiopulmonary bypass (CPB), cross-clamping the aorta, de-clamping the aorta, and end of CPB; also after starting the re-warming phase and at 10, 20, 30, and 40 min following. The mean difference between BIS and SE (Bland-Altman) was 2.14 (+16/- 11; 95% CI 1.59-2.67), and between BIS and RE it was 0.02 (+14/- 14; 95% CI 0.01-0.06). BIS and SE (r(2) = 0.66; P = 0.001) and BIS and RE (r(2) = 0.7; P = 0.001) were closely correlated (Pearson's). EEG parameters, EMG values, and systolic blood pressure significantly increased after skin incision, and sternotomy. The effect of surgical stimulation (Cohen's d) was highest for RE after skin incision (-0.71; P = 0.0001) and sternotomy (-0.94; P = 0.0001). Agreement was poor between the BIS index measured by BIS VISTA™ and SE values at critical anesthesia time points in patients undergoing cardiac surgery. RE was a good predictor of arousal after surgical stimulation regardless of the surgical level of muscle relaxation. Index differences most likely resulted from different algorithms for calculating consciousness level.

Two pilot trials and one study in a closely related grebe species suggest that Western grebes (Aechmophorus occidentalis) will not tolerate intracoelomic transmitter implantation with percutaneous antennae and often die within days of surgery. Wild Western grebes (n = 21) were captured to evaluate a modified surgical technique. Seven birds were surgically implanted with intracoelomic transmitters with percutaneous antennae by using the modified technique (transmitter group), 7 received the same surgery without transmitter implantation (celiotomy group), and 7 served as controls (only undergoing anesthesia). Modifications included laterally offsetting the body wall incision from the skin incision, application of absorbable cyanoacrylate tissue glue to the subcutaneous space between the body wall and skin incisions, application of a waterproof sealant to the skin incision after suture closure, and application of a piece of porcine small intestine submucosa to the antenna egress. Survival did not differ among the 3 groups with 7 of 7 control, 6 of 7 celiotomy, and 6 of 7 transmitter birds surviving the 9-day study. Experimental birds were euthanized at the end of the study, and postmortem findings indicated normal healing. Significant differences in plasma chemistry or immune function were not detected among the 3 groups, and only minor differences were detected in red blood cell indices and plasma proteins. After surgery, the birds in the transmitter group spent more time preening tail feathers than those in the control and celiotomy groups. These results demonstrate that, in a captive situation, celiotomy and intracoelomic transmitter implantation caused minimal detectable homeostatic disturbance in this species and that Western grebes can survive implantation of intracoelomic transmitters with percutaneous antennae. It remains to be determined what potential this modified surgical procedure has to improve postoperative survival of Western grebes that are intracelomically implanted with transmitters with percutaneous antennae and released into the wild.

Surgical instruments capable of sealing blood vessels while incising skin were compared to standard scalpel incisions in rats and the resultant scars examined in the early stages of wound healing for both gross and histological appearances. Those instruments which provide for hemostasis appear to do so with a delay in the early phases of wound healing.

Although single-incision laparoscopic cholecystectomy is now widely performed in patients with cholecystitis, some cases require an additional port to complete the procedure. In this study, we focused on risk factor of additional port in this surgery. We performed single-incision cholecystectomy in 75 patients with acute cholecystitis or after cholecystitis between 2010 and 2014 at Gunma University Hospital. Surgical indications followed the TG13 guidelines. Our standard procedure for single-incision cholecystectomy routinely uses two needlescopic devices. We used logistic regression analysis to identify the risk factors associated with use of an additional full-size port (5 or 10 mm). Surgical outcome was acceptable without biliary injury. Nine patients (12.0%) required an additional port, and one patient (1.3%) required conversion to open cholecystectomy because of severe adhesions around the cystic duct and common bile duct. In multivariate analysis, high C-reactive protein (CRP) values (>7.0 mg/dl) during cholecystitis attacks were significantly correlated with the need for an additional port (P = 0.009), with a sensitivity of 55.6%, specificity of 98.5%, and accuracy of 93.3%. This study indicated that the severe inflammation indicated by high CRP values during cholecystitis attacks predicts the need for an additional port. J. Med. Invest. 64: 245-249, August, 2017.

To explore the clinical application of mastectomy with single incision followed by immediate laparoscopic-assisted breast reconstruction with latissimus dorsi muscle flap. Fifteen women with primary early breast cancer, 3 women with breast ductal carcinoma in situ, and 7 women with severe plasma cell mastitis were treated with partial mastectomy or total mastectomy, sentinel lymph node biopsy, or axillary lymph node dissection through a breast lateral transverse incision. Subsequent breast reconstruction with latissimus dorsi muscle flap was assisted by laparoscopy. The patient's position, time used in dissecting latissimus dorsi muscle flap, size of latissimus dorsi muscle flap, postoperative complications, and the cosmetic results after reconstruction were assessed. All the operations were well done through the breast lateral transverse incision and assistance of laparoscopy. The patient's position was changed only once during the operation. It took 1.5 to 2 hours to dissect latissimus dorsi muscle flap. The sizes of the latissimus dorsi muscle flap were 5 to 8 × 12 to 16 cm. There were no serious postoperative complications noted. The patients were satisfied with the appearance of the breasts and the small surgical scar. The surgical approach introduced is minimally invasive with concealed scar and outstanding cosmetic results. It is worth promoting in clinical application.

With the advancement of laparoscopic devices and surgical technology, the era of minimal invasive surgery has progressed to reduced-port surgery, and finally to single-incision laparoscopic surgery (SILS). Several reports show successful application of SILS to various types of bariatric surgery. Oftentimes, this requires a skilled and experienced scopist to perform the procedure. To overcome the technical difficulties of single-incision Roux-en-Y gastric bypass, a manual scope holder was used instead of an assistant scopist, greatly stabilizing the field of view. This allows the surgery to be performed at any time without being influenced by the need of a highly experienced scopist. In this report, we describe in detail the world's first solo single-incision laparoscopic resectional Roux-en-Y gastric bypass.

To present the feasibility of no skin incision orchiopexy in children with concomitant hypospadias and undescended testis (UDT) by a single subcoronal incision technique. To introduce the creation of subdartos muscle scrotal pouch with no scrotal skin incision. From one thousand and twenty-one children with hypospadias, 61 patients presented with concomitant palpable UDT and hypospadias. In group I (N = 34) single subcoronal incision with no scrotal skin incision was applied. In group II (N = 27), multi-incision technique was applied for classical orchiopexy and hypospadias surgery. For hypospadias reconstruction, all patients had classical subcoronal and para urethral plate incision with penile skin degloving according to the location of urethral meatus. Early and late complications, surgical time, hospital stay, and cosmetic results were recorded. Children with unilateral UDT and hypospadias had one incision in group I and three skin incisions in group II. Patients with bilateral UDT had one incision in group I and five skin incisions in group II. The operation time was significantly shorter in group I (93 ± 11 min) compared with group II (138 ± 17 min) (P = 0.03). Both groups were operated as day care basis; however, the hospital stay was slightly longer in group II (group I = 12 ± 2 h, vs group II = 16 ± 3 h) (P = 0.07). All testes were satisfactorily positioned into the bottom of the scrotum without development of any testicular atrophy. Single subcoronal penile skin incision is a feasible, safe, and cosmetically satisfactory technique in patients with hypospadias and concomitant UDT. Reduced postoperative pain, better objective cosmetic results, shorter operative time and comfortable post-operative period are the most significant advantages of this approach.

Neck dissection is one of the most commonly performed surgical procedures in the management of head and neck cancer. Different skin incisions with various modifications have been described in the literature. Three commonly used but conceptually different incisions were compared with respect to the incidence of wound dehiscence in a retrospective review. There were 166 patients with 184 neck dissections carried out using a triradiate (n = 85), modified MacFee (n = 25), or an apron flap incision (n = 74). The incidence of wound dehiscence in the three groups was 11 percent, 8 percent, and 0 percent for the triradiate, modified MacFee, and apron flap incisions, respectively. There was a statistically significant difference in the incidence of wound dehiscence between the apron flap incision and the triradiate incision groups (p = 0.004). The difference in wound dehiscence was not statistically significant between the apron flap incision and the modified MacFee incision groups (p = 0.06). Overall, there was a significant increase in the incidence of wound dehiscence in previously irradiated necks (p = 0.02), but this was significant only for the triradiate incision (p = 0.005) when analyzed individually. Comparison of triradiate, apron, and MacFee incisions did not show a statistically significant difference between the incisions with regard to other postoperative complications in terms of seroma, hematoma, wound infection, and fistula formation. The apron flap incision is the recommended approach in the presence of previous neck irradiation as it gives easier access than the MacFee incision. The robustness of the flap is because of the absence of a trifurcate point as well as a good vascular supply arising from arterial territory of the external carotid artery.

Cataract surgery has undergone various advances since it was evolved from ancient couching to the modern phacoemulsification cataract surgery. Surgically induced astigmatism (SIA) remains one of the most common complications. The introduction of sutureless clear corneal incision has gained increasing popularity worldwide because it offers several advantages over the traditional sutured limbal incision and scleral tunnel. A clear corneal incision has the benefit of being bloodless and having an easy approach, but SIA is still a concern. In this study, we evaluated the SIA in clear corneal incisions with temporal approach and superior approach phacoemulsification. Comparisons between the two incisions were done using keratometric readings of preoperative and postoperative refractive status. It was a hospital-based prospective interventional comparative randomized control trial of 261 patients conducted in a rural-based tertiary care center from September 2012 to August 2014. The visual acuity and detailed anterior segment and posterior segment examinations were done and the cataract was graded according to Lens Opacification Classification System II. Patients were divided for phacoemulsification into two groups, group A and group B, who underwent temporal and superior clear corneal approach, respectively. The patients were followed up on day 1, 7, 30, and 90 postoperatively. The parameters recorded were uncorrected visual acuity, best-corrected visual acuity, slit lamp examination, and keratometry. The mean difference of SIA between 30th and 90th day was statistically evaluated using paired t -test, and all the analyses were performed using SPSS 18.0 (SPSS Inc.) software. The mean postoperative SIA in group A was 0.998 D on the 30th day, which reduced to 0.768 D after 90 days, and in group B the SIA after 30 days was 1.651 D, whereas it reduced to 1.293 D after 90 days. Temporal clear corneal incision is evidently better than superior clear corneal incision as far as SIA is concerned.

Optimal Suturing Technique and Number of Sutures for Surgical Implantation of Acoustic Transmitters in Juvenile Salmonids

The size reduction of acoustic transmitters has led to a reduction in the length of incision needed to implant a transmitter. Smaller suture knot profiles and fewer sutures may be adequate for closing an incision used to surgically implant an acoustic microtransmitter. As a result, faster surgery times and reduced tissue trauma could lead to increased survival and decreased infection for implanted fish. The objective of this study was to assess the effects of five suturing techniques on mortality, tag and suture retention, incision openness, ulceration, and redness in juvenile Chinook salmon Oncorhynchus tshawytscha implanted with acoustic microtransmitters. Suturing wasmore » performed by three surgeons, and study fish were held at two water temperatures (12°C and 17°C). Mortality was low and tag retention was high for all treatments on all examination days (7, 14, 21, and 28 days post-surgery). Because there was surgeon variation in suture retention among treatments, further analyses included only the one surgeon who received feedback training in all suturing techniques. Incision openness and tissue redness did not differ among treatments. The only difference observed among treatments was in tissue ulceration. Incisions closed with a horizontal mattress pattern had more ulceration than other treatments among fish held for 28 days at 17°C. Results from this study suggest that one simple interrupted 1 × 1 × 1 × 1 suture is adequate for closing incisions on fish under most circumstances. However, in dynamic environments, two simple interrupted 1 × 1 × 1 × 1 sutures should provide adequate incision closure. Reducing bias in survival and behavior tagging studies is important when making comparisons to the migrating salmon population. Therefore, by minimizing the effects of tagging on juvenile salmon (reduced tissue trauma and reduced surgery time), researchers can more accurately estimate survival and behavior.« less

Excision and Patch Grafting of a Lateral Peyronie's Plaque-Utilizing a Longitudinal "Window" Approach.

Peyronie's disease (PD) is a debilitating disorder in which collagen deposition, fibrosis, and plaques in the tunica albuginea result in penile curvature, shortening, and pain. For severe curvatures requiring plaque incision or excision with grafting (PIEG), a subcoronal circumcising incision with penile degloving has historically been used. The aim of this study was to report our unique approach to PIEG via a longitudinal "window" incision for the correction of PD, minimizing the surgical manipulation and dissection accompanying the traditional circumcising incisional approach that may lead to increased postoperative edema, pain, and prolonged healing time. A patient presented with a stable, painless, 90-degree midshaft leftward curvature causing penetration difficulties and painful intercourse for his partner. His Sexual Health Inventory for Men (SHIM) score was 23. The patient opted for surgical correction with plaque excision and grafting via a 4-cm longitudinal incision overlying the point of maximal curvature along the left lateral penile shaft. This direct access to the left corpus cavernosum and plaque, along with dissecting skin, dartos, and Buck's fascia, created a window with sufficient exposure for excision and patch grafting. The main outcome measures were objective data and subjective data in men undergoing PIEG via lateral longitudinal "window" incision for PD repair. The plaque was excised and a porcine small intestinal submucosa graft was sewn in. Intraoperative artificial tumescence at the end of surgery revealed complete correction of the curvature. The patient experienced painless rigid erections by postoperative day three with minimal penile edema. By postoperative week four, he could successfully partake in coitus. His SHIM score remained unchanged. At maximum follow-up 6 months postoperatively, he still endorsed excellent cosmetic and functional outcomes with spontaneous unassisted erections and no recurrence of his curvature. A lateral longitudinal incision for PIEG is a feasible technique and may reduce the postoperative morbidity and dissection required with traditional circumcising incision with penile degloving. Larger comparative studies are necessary for further evaluation.

To compare the punch technique and linear incision with soft tissue reduction for the placement of auditory osseointegrated implants (AOI) and analyze results of osseointegration obtained with the punch technique as measured with the Implant Stability Quotient (ISQ). Case review of 34 patients who received auditory osseointegrated implants between January 2010 and July 2015 and were divided into two groups according to the surgical technique: 18 with the punch technique (PT) and 16 with the linear incision technique (LI). Minimum follow-up was four months (mean: 24 months; range 4-64 months). Included in the analysis were patient profiles and records of the demographic data, surgical indications, surgical technique, implant placement, surgical time, intraoperative complications, as well as postsurgical complications (Holgers classification) and implant stability quotients (ISQ). Use of larger abutments was significantly greater in the PT group (PT, 10mm; LI, 6mm, p<0.001). The PT technique resulted in a shorter procedure than the LI (PT, 20min; LI, 45min, p<0.001). Holgers classification scores identified significantly fewer skin complications one week after surgery for the PT group; however, only small differences were seen between the two groups at the one- and three-month control visits. As shown for our cohort, the punch technique for surgical placement of AOI is faster and presents fewer immediate postoperative complications when compared to the linear incision technique. The clinical application of the ISQ is a useful, easy method to demonstrate the status of osseointegration and, thus, the stability of the device.

To compare maternal outcomes after transection and after avoiding incision of the anterior placenta previa during cesarean delivery. In a retrospective study, records were reviewed for women who had anterior placenta previa and delivered by cesarean after 24 weeks of pregnancy at a tertiary center in Rouen, France. During period A (January 2000 to December 2006), the protocol was to systematically transect the placenta when it was unavoidable. During period B (January 2007 to December 2010), the technique was to avoid incision by circumventing the placenta and passing a hand around its margin. Logistic regression was used to identify independent risk factors associated with maternal transfusion of packed red blood cells. Eighty-four women were included (period A: n=43; period B: n=41). During period B, there was a reduction in frequency of intraoperative hemorrhage (>1000 mL) (P=0.02), intraoperative hemoglobin loss (P=0.005), and frequency of blood transfusion (P=0.02) as compared with period A. In multivariable analysis, period B was associated with a reduced risk of maternal transfusion (odds ratio 0.27; 95% confidence interval 0.09-0.82; P=0.02). Avoiding incision of the anterior placenta previa was found to reduce frequency of maternal blood transfusion during or after cesarean delivery.

Background and Objectives: For reduced port surgery in pediatric patients, the initial umbilical incision plays an important role in both functional ability and cosmetic impact. Larger umbilical incisions enable better manipulation of forceps, extraction of larger surgical specimens, and easier exteriorization of the intestine for anastomosis. We have pursued an incision of the small pediatric umbilicus that allows for enlargement of the orifice of the abdominal opening with preservation of the natural umbilical profile. This article aims to present a new umbilical incision technique and describe the outcomes. Methods: We devised a new umbilical incision technique for reduced port surgery in pediatric patients. Our incision is made in an inverted Y shape (Benz incision), allowing for access port device insertion. The Benz incision technique was applied between November 2010 and May 2014 and was retrospectively studied. Results: Seventy-five patients underwent Benz incisions. The median age of all patients was 6 years 6 months (range, 26 days to 18 years), and the median body weight was 21.7 kg (range, 3.1–54.3 kg). Benz incisions were applied for various procedures, including reduced port surgery with hepaticojejunostomy for congenital biliary dilatation, portojejunostomy for biliary atresia, Meckel diverticulectomy, tumor resection, varicocelectomy, cholecystectomy, splenectomy, ileus surgery, ileocecal resection, and total colectomy. All patients were successfully treated, without a significant increase in operating time or severe complications. The cosmetic profile of the umbilicus was maintained after surgery. Conclusion: The Benz incision is a feasible, effective, and scarless approach for reduced port surgery in pediatric patients whose umbilical rings are too small for the conventional approach.

Appendicitis is the most common emergent problem encountered by pediatric surgeons. Driven by improved cosmetic outcomes, many surgeons are offering pediatric patients single-incision laparoscopic appendectomy. We sought to investigate the financial impact of different surgical approaches to appendectomy. A retrospective study of patients with acute appendicitis undergoing appendectomy from February 2010 to September 2011 was conducted. Based on surgeon preference, patients underwent open appendectomy (OA), laparoscopic appendectomy (LA), or single-incision laparoscopic appendectomy (SILA). Demographic information, surgical outcomes, surgical supply costs, and total direct costs were recorded. A total of 465 patients underwent appendectomy during the study. The mean age of all patients was 11.2 years (range, 1 to 18 years). There were no conversions in the LA or SILA groups. There was a significant difference among surgical technique in regard to surgical supply costs (OA $159 vs. LA $650 vs. SILA $814, P < 0.01) and total direct costs (OA $2129 vs. LA $2624 vs. SILA $2991, P < 0.01). In our institution, both multiport laparoscopic and SILA carry higher costs when compared with OA, largely as a result of the cost of disposable instrumentation. Cost efficiency should be considered by surgeons when undertaking a minimally invasive approach to appendectomy.

To evaluate the change and difference in the corneal surface, incision, and handpiece temperatures during longitudinal and torsional ultrasound (US) phacoemulsification with standard incisions (2.75 mm) and microincisions (2.20 mm) and the thermal effect on wounds. Department of Ophthalmology, Duke University, Durham, North Carolina, USA. In this prospective study, human cadaver eyes had simulated phacoemulsification. Group 1 had a 2.75 mm incision with 100% longitudinal US; Group 2, a 2.20 mm incision with 100% longitudinal US; Group 3, a 2.75 mm incision with 100% torsional US; and Group 4, a 2.20 mm incision with 100% torsional US. During phacoemulsification, the corneal incision was evaluated by surgical microscopy and scanning electron microscopy (SEM) and images of the corneal surface, incision, and handpiece were captured with an infrared camera. Twelve eyes (3 each group) were evaluated. The maximum incision temperature was higher in the longitudinal groups than in the torsional groups. With the same US modality, the maximum microincision temperature was higher than the maximum standard incision temperature. After application of full power for 40 seconds, wound burn was observed in all eyes in the longitudinal groups and no eyes in the torsional groups. On SEM, there was more extensive loss of Descemet membrane in the longitudinal groups than in the torsional groups. Incision temperature was influenced by US modality and was significantly lower with torsional US than with longitudinal US. Using torsional US with smaller incisions may decrease the risk for wound burn in eyes with denser cataracts. (c) 2010 ASCRS and ESCRS. Published by Elsevier Inc. All rights reserved.

To evaluate first-intention healing of CO(2) laser, 4.0-MHz radiowave radiosurgery (RWRS), and scalpel incisions in ball pythons (Python regius). 6 healthy adult ball pythons. A skin biopsy sample was collected, and 2-cm skin incisions (4/modality) were made in each snake under anesthesia and closed with surgical staples on day 0. Incision sites were grossly evaluated and scored daily. One skin biopsy sample per incision type per snake was obtained on days 2, 7, 14, and 30. Necrotic and fibroplastic tissue was measured in histologic sections; samples were assessed and scored for total inflammation, histologic response (based on the measurement of necrotic and fibroplastic tissues and total inflammation score), and other variables. Frequency distributions of gross and histologic variables associated with wound healing were calculated. Gross wound scores were significantly greater (indicating greater separation of wound edges) for laser incisions than for RWRS and scalpel incisions at all evaluated time points. Necrosis was significantly greater in laser and RWRS incisions than in scalpel incision sites on days 2 and 14 and days 2 and 7, respectively; fibroplasia was significantly greater in laser than in scalpel incision sites on day 30. Histologic response scores were significantly lower for scalpel than for other incision modalities on days 2, 14, and 30. In snakes, skin incisions made with a scalpel generally had less necrotic tissue than did CO(2) laser and RWRS incisions. Comparison of the 3 modalities on the basis of histologic response scores indicated that use of a scalpel was preferable, followed by RWRS and then laser.

Trends in the Surgical Correction of Gynecomastia.

Brown, Rodger H; Chang, Daniel K; Siy, Richard; Friedman, Jeffrey

2015-05-01

Gynecomastia refers to the enlargement of the male breast due to a proliferation of ductal, stromal, and/or fatty tissue. Although it is a common condition affecting up to 65% of men, not all cases require surgical intervention. Contemporary surgical techniques in the treatment of gynecomastia have become increasingly less invasive with the advent of liposuction and its variants, including power-assisted and ultrasound-assisted liposuction. These techniques, however, have been largely limited in their inability to address significant skin excess and ptosis. For mild to moderate gynecomastia, newer techniques using arthroscopic morcellation and endoscopic techniques promise to address the fibrous component, while minimizing scar burden by utilizing liposuction incisions. Nevertheless, direct excision through periareolar incisions remains a mainstay in treatment algorithms for its simplicity and avoidance of additional instrumentation. This is particularly true for more severe cases of gynecomastia requiring skin resection. In the most severe cases with significant skin redundancy and ptosis, breast amputation with free nipple grafting remains an effective option. Surgical treatment should be individualized to each patient, combining techniques to provide adequate resection and optimize aesthetic results.

Endoscope-Assisted Transoral Fixation of Mandibular Condyle Fractures: Submandibular Versus Transoral Endoscopic Approach.

PubMed

Hwang, Na-Hyun; Lee, Yoon-Hwan; You, Hi-Jin; Yoon, Eul-Sik; Kim, Deok-Woo

2016-07-01

In recent years, endoscope-assisted transoral approach for condylar fracture treatment has attracted much attention. However, the surgical approach is technically challenging: the procedure requires specialized instruments and the surgeons experience a steep learning curve. During the transoral endoscopic (TE) approach several instruments are positioned through a narrow oral incision making endoscope maneuvering very difficult. For this reason, the authors changed the entry port of the endoscope from transoral to submandibular area through a small stab incision. The aim of this study is to assess the advantage of using the submandibular endoscopic intraoral approach (SEI).The SEI approach requires intraoral incision for fracture reduction and fixation, and 4 mm size submandibular stab incision for endoscope and traction wires. Fifteen patients with condyle neck and subcondyle fractures were operated under the submandibular approach and 15 patients with the same diagnosis were operated under the standard TE approach.The SEI approach allowed clear visualization of the posterior margin of the ramus and condyle, and the visual axis was parallel to the condyle ramus unit. The TE approach clearly shows the anterior margin of the condyle and the sigmoid notch. The surgical time of the SEI group was 128 minutes and the TE group was 120 minutes (P >0.05). All patients in the TE endoscope group were fixated with the trocar system, but only 2 lower neck fracture patients in the SEI group required a trocar. The other 13 subcondyle fractures were fixated with an angulated screw driver (P <0.05). There were no differences in complication and surgical outcomes.The submandibular endoscopic approach has an advantage of having more space with good visualization, and facilitated the use of an angulated screw driver.

This study aimed to investigate whether celastrol (CEL) could alleviate incision-induced pain and decipher its possible mechanism. Sprague-Dawley rats were randomly divided into five groups: naïve, vehicle, CEL (5 μg/paw, 10 μg/paw and 20 μg/paw). CEL or vehicle was administered intraplantarly before plantar surgical incision. Histological examinations of skin tissues were performed after HE staining. Additionally, immunohistochemical staining, RT-PCR and western blot were performed to analyse macrophages, proinflammatory cytokines, SARM and NF-κB expression, respectively. Moreover, the previous mentioned factors were re-evaluated after suppressing SARM expression by shRNA. The plantar incision rats displayed pain-related behaviours and inflammatory infiltration in the skin. The mRNA levels of proinflammatory cytokines, such as IL-1β, IL-6, and TNFα were significantly upregulated in the skin of surgical rats. The expression of sterile α- and armadillo-motif-containing protein (SARM) was downregulated and nuclear factor kappa-B (NF-κB) was activated. Interestingly, CEL could partially restore the pain-related behavioural changes. Furthermore, molecular mechanism of CEL was explored, that included significantly reduction of proinflammatory cytokines mRNA expressions, a significant decrease of p-p65 and p65 levels and a markedly increase of SARM and IkBα expressions in skin tissues. However, supression SARM by shRNA partially eliminated those protective effect of CEL. Our data suggest that intraplantarly administration of CEL attenuates inflammatory and acute pain. This finding could be attributed to regulation of the NF-κB signalling pathway via SARM. These results provide pre-clinical evidence supporting the use of CEL in the treatment of surgical pain.

Yamamoto, Takumi; Yoshimatsu, Hidehiko; Hayashi, Akitatsu; Koshima, Isao

The treatment of deep pressure ulcer with a wide wound edge undermining (pocket) is challenging, especially when conservative treatments are ineffective. As most patients with a pressure ulcer suffer from systemic comorbidities, invasive surgery cannot be performed on all patients, and less invasive treatment is required. Less invasive surgical intervention to a deep pressure ulcer, parallel pocket incision (PPI), was performed on 10 patients with intractable pressure ulcers with a pocket formation. In PPI procedures, two parallel skin incisions were made to open up the deepest fold of the pocket and to preserve the skin overlying the pocket lesion; through the created incisions, the necrotic tissues around the deepest fold of the undermining could be easily removed, which facilitated spontaneous wound healing. Postoperative results and complications were evaluated. All PPI procedures were safely performed under local infiltration anesthesia without major postoperative complication; minor bleeding was seen intraoperatively in three patients, which could be easily controlled with electric cautery coagulation. Nine of 10 ulcers were cured after PPI, and one could not be followed up due to the patient's death non-related to the pressure ulcer. For the nine cured patients, the average time for cure was 14.9 weeks, and no recurrence was observed at postoperative 6 months. PPI is a simple, technically easy, and less invasive surgical intervention to an intractable pressure ulcer with a pocket, which can be safely performed under local infiltration anesthesia even on a patient with severe systemic comorbidities.

Shamim, Muhammad

2009-08-01

This prospective, double-blind, randomized, controlled trial was designed to compare the outcome of diathermy incisions versus scalpel incisions in general surgery. A total of 369 patients who underwent diathermy incision (group A: 185 patients) or scalpel incision (group B: 184 patients) were analyzed. Variables analyzed were: surgical wound classification, length and depth of incision, incision time, duration of operation, incisional blood loss, postoperative pain, duration of hospital stay, duration of healing, and postoperative complications. The inclusion criteria were all patients who underwent elective or emergency general surgery. The exclusion criteria were only cases with incomplete patients' data and patients who were lost to follow-up. This study was conducted at Fatima Hospital-Baqai Medical University and Shamsi Hospital (Karachi), from January 2006 to December 2007. Incision time was significantly longer for patients in group B (p = 0.001). Incisional blood loss also was more for patients in group B (p = 0.000). Pain perception was found to be markedly reduced during the first 48 h in group A (p = 0.000). Total period of hospital stay (p = 0.129) and time for complete wound healing (p = 0.683) were almost the same for both groups. Postoperative complication rate by wound classification did not differ markedly between the two groups (p = 0.002 vs. p = 0.000). Diathermy incision has significant advantages compared with the scalpel because of reduced incision time, less blood loss, & reduced early postoperative pain.

Cranial nerve injury (CNI) is the most common neurological complication associated with carotid endarterectomy (CEA). Some authors postulate that the transverse skin incision leads to increased risk of CNI. We compared the incidence of CNI associated with the transverse and longitudinal skin incisions in a high-volume cerebrovascular center. We reviewed the charts of 226 consecutive patients who underwent CEAs between January 2007 and August 2009. Pre- and postoperative standardized neurological evaluations were performed by faculty neurologists and neurosurgeons. One hundred sixty nine of 226 (75%) CEAs were performed with the use of a transverse incision. The longitudinal incision was generally reserved for patients with a high-riding carotid bifurcation. Mean patient age was 69 years (range, 45-91 years); 62% were men; 59% of patients were symptomatic and had high-grade stenosis (70%-99%). CNI occurred in 8 cases (3.5%): 5 (3%) in transverse and 3 (5.3%) with longitudinal incisions (P = .42). There were 2 marginal mandibular nerve injuries, 1 (0.6%) transverse and 1 longitudinal; 5 recurrent laryngeal nerve injuries, 4 transverse and 1 longitudinal; and 1 case of hypoglossal nerve injury associated with longitudinal incision. One hematoma was associated with CNI. All injuries were transient. Fourteen wound hematomas required surgical evacuation. The transverse skin incision for CEAs is not associated with an increased risk of CNI (P =.42). In this study, the incidence of CNI associated with the transverse incision was 3% (n = 5) vs 5% (n = 3) for longitudinal incisions. All CNIs were temporary.

To evaluate the current state of abortion training in Canadian Obstetrics and Gynecology residency programs. Surveys were distributed to all Canadian Obstetrics and Gynecology residents and program directors. Data were collected on inclusion of abortion training in the curriculum, structure of the training and expected competency of residents in various abortion procedures. We distributed and collected surveys between November 2014 and May 2015. In total, 301 residents and 15 program directors responded, giving response rates of 55% and 94%, respectively. Based on responses by program directors, half of the programs had "opt-in" abortion training, and half of the programs had "opt-out" abortion training. Upon completion of residency, 66% of residents expected to be competent in providing first-trimester surgical abortion in an ambulatory setting, and 35% expected to be competent in second-trimester surgical abortion. Overall, 15% of residents reported that they were not aware of or did not have access to abortion training within their program, and 69% desired more abortion training during residency. Abortion training in Canadian Obstetrics and Gynecology residency programs is inconsistent, and residents desire more training in abortion. This suggests an ongoing unmet need for training in this area. Policies mandating standardized abortion training in obstetrics and gynecology residency programs are necessary to improve delivery of family planning services to Canadian women. Abortion training in Canadian Obstetrics and Gynecology residency programs is inconsistent, does not meet resident demand and is unlikely to fulfill the Royal College of Physicians and Surgeons of Canada objectives of training in the specialty.

Context: Electric stimulation is frequently used to promote soft tissue healing, although we do not have a complete understanding of the tissue's electromagnetic properties. Objective: To measure the transient electric changes in skin and muscle tissue immediately after trauma. Design: 1-group time series. Setting: Climate-controlled operating room in a public urban hospital. Patients or Other Participants: Eleven participants (8 females, 3 males) with a mean age of 65.18 ± 11.36 years undergoing total hip arthroplasty. Intervention(s): An incision approximately 10 cm distal to the posterior superior iliac spine extended distally over the greater trochanter and along the lateral limb. The incision was completed in 2 cuts: (1) skin and subcutaneous fat and (2) muscle tissue. Main Outcome Measure(s): Three measurement sessions were performed with an electrometer before and after a skin incision and after a muscle incision. Potential differences and current intensity were measured immediately after acute trauma to determine the transient electric changes associated with soft tissue injury. Results: The electric potentials were significantly more negative after the skin incision (P = .036) and skin plus muscle incision (P = .008; preincision = 0.001 ± 0.015 V, skin incision = −0.127 ± 0.134 V, skin plus muscle incision = −0.192 ± 0.153V). Current intensity changed significantly after the skin plus muscle incision (P = .008; preincision = 0.046 ± 0.112 pA, skin incision = −0.803 ± 0.904 pA, skin plus muscle incision = −1.708 ± 1.302 pA). Conclusions: Soft tissue trauma generated negative transient electric changes. PMID:18174941

Coronal incision is a popular and versatile surgical approach to the anterior cranial vault and upper and middle third facial skeleton. The flap itself permits widespread exposure of the fractures in this region. The bicoronal flap was first described by Hartley and Kenyon (neurosurgeons) to gain access to the anterior cranium in 1907. It extension as an access flap to the upper and lateral aspect of the face was pioneered by Tessier (1971). Esthetically, it is pleasing as the surgical scar is hidden within the hair. To evaluate the versatility of coronal incision using various modifications advocated in incision, exposure to fractured site, and closure of flap in treating the upper and middle third facial fractures. A total of ten patients diagnosed with upper and middle third facial fractures requiring open reduction and internal fixation/correction of contour defect were selected after preoperative clinical and radiographic (computed tomography scan) evaluation. All the cases were operated by coronal approach to gain the access to the fracture/defect site for reduction/correction of the defect. Advantages and complication are evaluated. Excellent access and anatomical reduction by this approach with least number of complications; if it is performed with healthy knowledge of anatomy of the scalp and temporal region. Certain minimal complications have also been noted using various modifications used in the procedure. Despite of prolonged surgical time for the exposure, it is very advantages in treating upper and middle third facial fractures due to wide access and discreet scar (minimal).

In recent years, funds for global health have risen substantially, particularly for infectious diseases. Although conditions amenable to surgery account for 28% of the global burden of disease, the external funds directed towards global surgical delivery, capacity building, and research are currently unknown and presumed to be low. We aimed to describe external funds given to these efforts from the USA, the world's largest donor nation. We searched the United States Agency for International Development (USAID), National Institute of Health (NIH), Foundation Center, and registered US charitable organisations databases for financial data on any giving exclusively to surgical care in low-income and middle-income countries (LMICs). All nominal dollars were adjusted for inflation by converting to 2014 US dollars. After adjustment for inflation, 22 NIH funded projects (totalling US$31·3 million, 1991-2014) were identified; 78·9% for trauma and injury, 12·5% for general surgery, and 8·6% for ophthalmology. Six relevant USAID projects were identified; all related to obstetric fistula care totalling US$438 million (2006-13). US$105 million (2003-13) was given to universities and charitable organisations by US foundations for 14 different surgical specialties (ophthalmology, cleft lip/palate, multidisciplinary teams, orthopaedics, cardiac, paediatric, reconstructive, obstetric fistula, neurosurgery, burn, general surgery, obstetric emergency procedures, anaesthesia, and unspecified specialty). 95 US charitable organisations representing 14 specialties (ophthalmology, cleft lip/palate, multidisciplinary teams, orthopaedics, cardiac, paediatric, reconstructive, obstetric fistula, neurosurgery, urology, ENT, craniofacial, burn, and general surgery) totalled revenue of US$2·67 billion and expenditure of US$2·5 billion (2007-13). A strong surgical system is an indispensable part of any health system and requires financial investment. Tracking funds targeting surgery helps not only to quantify and clarify this investment, but also to ultimately serve as a platform to integrate surgical spending within health system strengthening. Although USAID is a vital foreign aid service and the NIH is a leader in biomedical and health research, their surgical scopes are restricted both financially (less than 1% of respective total budgets over the study years) and in surgical specialty. By contrast, the private charitable sector has contributed more financially and to more specialties. Still, current financial global health databases do not have precise data for surgery. To improve population health in LMICs, more resources should be dedicated to surgical system strengthening. Furthermore, exact classification measures should be implemented to track these important resources. None. Copyright © 2015 Elsevier Ltd. All rights reserved.

Creating a Full-thickness Choroidal Incision: An Ex Vivo Analysis of Human and Porcine Tissue Contraction Dynamics

Purpose We hypothesized that the elastic nature of the choroid leads to tissue contraction following a full-thickness, sharp incision. Furthermore, we sought to quantify, measure, and compare tissue contraction in ex vivo porcine globes and human globes of various ages using predetermined variables. Method A full-thickness, ex vivo choroidal incision was performed in either pig (n = 97) or human (n = 30) specimens. Variables included trephine diameter (1.5, 2.0, or 2.5 mm) versus a straight surgical blade, and temperature (1.7 °–4.4° vs. 36.6°F). Central centripetal and surround centrifugal tissue contractions were measured. Mean percentage tissue contraction was assessed as a ratio of trephine diameter to final tissue contraction measured immediately following each incision using a standardized device. Results For trephination in pig specimens, centripetal contraction ranged from 38% to 50% with a mean of 44%. Centrifugal contraction was approximately 15%. Human choroidal contraction was 39% and 15%, respectively, with a statistically significant inverse relationship to age (R2 = 0.35, P ≤ 0.01). Asymmetric contraction was noted when incisions were closer to choroidal attachment sites to the sclera, such as near vortex ampullae. Linear incisions resulted in contraction that correlated with incision length (R2 = 0.35, P ≤ 0.001). Conclusions A full-thickness choroidal incision results in significant tissue contraction. For circular incisions, the centripetal contraction approaches 50% of the original incision size. For linear incisions, the contraction corresponds directly with incision length. In human specimens, there is less contraction with advancing age. Translational Relevance Our findings have clinical relevance for choroidal biopsy, traumatic injury, and choroidal translocation surgery. PMID:29134136

Recent enthusiasm in the surgical community for less invasive surgical approaches has resulted in widespread application of single-incision techniques. This has been most commonly applied in laparoscopic cholecystectomy in general surgery. Cosmesis appears to be improved, but other advantages remain to be seen. Feasibility has been demonstrated, but there is little description in the current literature regarding complications. We report the case of a patient who previously underwent single-incision laparoscopic cholecystectomy for symptomatic gallstone disease. After a brief symptom-free interval, she developed acute pancreatitis. At evaluation, imaging results of ultrasonography and magnetic resonance cholangiopancreatography demonstrated a retained gallbladder with cholelithiasis. The patient was subsequently referred to our hospital, where she underwent further evaluation and surgical intervention. Our patient underwent 4-port laparoscopic remnant cholecystectomy with transcystic common bile duct exploration. Operative exploration demonstrated a large remnant gallbladder and a partially obstructed cystic duct with many stones. Transcystic exploration with balloon extraction resulted in duct clearance. The procedure took 75 minutes, with minimal blood loss. The patient's postoperative course was uneventful. Final pathology results demonstrated a remnant gallbladder with cholelithiasis and cholecystitis. This report is the first in the literature to describe successful laparoscopic remnant cholecystectomy and transcystic common bile duct exploration after previous single-port cholecystectomy. Although inadvertent partial cholecystectomy is not unique to this technique, single-port laparoscopic procedures may result in different and significant complications.

To compare the anatomic and refractive outcomes in eyes having phacoemulsification with 1 of 3 clear corneal incision (CCI) closure methods. Ambulatory surgical center, Makati, Philippines. Prospective randomized clinical trial. Patients having phacoemulsification cataract surgery had wound closure using no additional treatment (control), a single 10-0 nylon suture, or a liquid adhesive ocular bandage (Ocuseal). The main outcome measures were wound-edge closure rates, surgically induced astigmatism (SIA), foreign-body sensation, and intraocular pressure (IOP) 1, 3, 5, 7, and 14 days postoperatively. The study evaluated 90 eyes. There was a significant improvement in wound-edge closure rates in the suture group and the ocular bandage group compared with the control group (P<.001). A significant increase in SIA occurred in the sutured group but not in the control or ocular bandage groups (P<.001). The ocular bandage group had significantly less foreign-body sensation than the control and suture groups (P<.001). There were no significant differences in IOP between the groups (P=.515). The liquid adhesive ocular bandage resulted in improved wound-edge closure, reduced SIA, and diminished foreign-body sensation. Suturing was associated with improved wound-edge closure but increased SIA and foreign-body sensation. Unsutured incisions led to delayed wound-edge closure and increased foreign-body sensation.

The purpose of this study was to evaluate the effect of pre-emptive intravenous versus pre-emptive epidural morphine on both postoperative analgesic consumption and surgical stress response. Sixty patients, ASA I or II, aged 18-85, undergoing total hip or knee replacement were randomly assigned to three groups of 20 patients. In group pre-emptive epidural, patients were administered an epidural injection of 75 micrograms.kg-1 morphine about 45 minute before dermal incision. In group pre-emptive intravenous, patients were administered 0.15 mg.kg-1 of intravenous morphine following induction before dermal incision. In group control, patients were administered intravenous saline following induction before dermal incision. The pre-i.v. group used significantly less morphine than the pre-epi group (p < 0.0003). In all groups, plasma cortisol levels increased as compared to pre-op values, but plasma cortisol increased more significantly in the pre-i.v. and control groups within 4 hrs of surgery and was still significantly elevated at 7 am of the first postoperative morning compared to the pre-epi group (p < 0.001) and the increase persisted to the next morning in patients pre-i.v. and control groups. Although pre-emptive epidural morphine has failed to decrease postoperative analgesic consumption, it has been able to suppress the surgical stress more significantly than intravenous morphine and a saline control.

Comparison of transumbilical laparoscopic-assisted appendectomy versus single incision laparoscopic appendectomy in children: which is the better surgical option?

PubMed

Transumbilical laparoscopic-assisted appendectomy (TULA) is a single incision technique that exteriorizes the appendix through the umbilicus. The aim of this study was to compare the surgical outcomes of TULA with SILA in pediatric appendicitis. A retrospective review of medical records between April 2011 and April 2015 identified 250 pediatric patients who underwent single incision laparoscopic appendectomy. Of these, 137 patients underwent TULA and 113 patients underwent SILA. Measured outcomes included patients' demographics, clinical characteristics, operative time, length of stay, pain, and postoperative complications. TULA group had a shorter operative time than SILA group (28.93 vs. 49.19min, p<0.001). The use of rescue analgesics was more frequent in the SILA group (six cases (6.5%) vs. 19 cases (23.4%), p<0.001). There was no significant difference in cosmetic outcome between the two groups. However, TULA was associated with a lower complication rate (2/137, 1.5%) than SILA (11/113, 9.8%) (p=0.0035). In multiple logistic regression analysis, TULA was significantly associated with a lower complication rate (p=0.049). TULA is preferable to SILA for treating pediatric acute appendicitis because it is technically easier, results in better surgical outcomes, and provides the same excellent cosmetic results.

2015-01-01

Laparoscopic ovariohysterectomy using single-portal access was performed in nine selected owned dogs admitted for elective ovariohysterectomy and the surgical technique and outcomes were detailed. A multiport device (SILS Port, Covidien, USA) was placed at the umbilical area through a single 3 cm incision. Three cannulae were introduced in the multiport device through the access channels and laparoscopic ovariohysterectomy was performed using a 5-mm sealing device, a 5-mm articulating grasper and a 5-mm 30° laparoscope. The mean total operative time was 52.66±15.20 minutes and the mean skin incision during surgery was 3.09±0.20 cm. Of the nine cases examined, in the one with an ovarian tumour, the technique was converted to multiport laparoscopy introducing an additional 5-mm trocar. No surgical complications were encountered and intraoperative blood loss was minimum in all animals. Clashing of the instruments and reduced triangulation were the main limitations of this technique. The combination of articulated and straight instruments facilitated triangulation towards the surgical field and dissection capability. One month after surgery a complete wound healing was observed in all animals. The present data showed that ovariohysterectomy performed with a single-port access is technically feasible in dogs. The unique abdominal incision minimises the abdominal trauma with good cosmetic results. PMID:26568831

2016-01-01

Objectives Obstetric fistula is a maternal injury that causes uncontrollable leaking of urine or stool, and most women who develop it live in poverty in low-income countries. Obstetric fistula is associated with high rates of stigma and psychological morbidity, but there is uncertainty about the impact of surgical treatment on psychological outcomes. The objective of this exploratory study was to examine changes in psychological symptoms following surgical fistula repair, discharge and reintegration home. Methods Women admitted for surgical repair of obstetric fistula were recruited from a Tanzanian hospital serving a rural catchment area. Psychological symptoms and social functioning were assessed prior to surgery. Approximately 3 months after discharge, a data collector visited the patients' homes to repeat psychosocial measures and assess self-reported incontinence. Baseline to follow-up differences were measured with paired t tests controlling for multiple comparisons. Associations between psychological outcomes and leaking were assessed with t tests and Pearson correlations. Results Participants (N = 28) had been living with fistula for an average of 11 years. Baseline psychological distress was high, and decreased significantly at follow-up. Participants who self-reported continued incontinence at follow-up endorsed significantly higher PTSD and depression symptoms than those who reported being cured, and severity of leaking was associated with psychological distress. Conclusions Fistula patients experience improvements in mental health at 3 months after discharge, but these improvements are curtailed when women experience residual leaking. Given the rate of stress incontinence following surgery, it is important to prepare fistula patients for the possibility of incomplete cure and help them develop appropriate coping strategies.

Swords, Michael P; Penny, Phillip

2017-03-01

The treatment of calcaneus fractures is controversial. Historically, most operatively treated fractures have been approached with a lateral extensile incision requiring delay in operative treatment until swelling has improved. There is a current trend and interest in small incision approaches allowing, and in some cases requiring, earlier operative fixation. Clinical scenarios amenable to consideration for early fixation are reviewed. The sinus tarsi surgical approach and reduction techniques are outlined in detail. Copyright © 2016 Elsevier Inc.

100-Hz Electroacupuncture but not 2-Hz Electroacupuncture is Preemptive Against Postincision Pain in Rats.

PubMed

Silva, Marcelo Lourenço; Silva, Josie Resende Torres; Prado, Wiliam Alves

2016-08-01

Preemptive analgesia involves introducing an analgesic before noxious stimulation. Electroacupuncture (EA) activates descending mechanisms that modulate nociceptive inputs into the spinal dorsal horn. This study evaluated whether preoperative EA is more effective than postoperative EA in reducing incision pain in rats. The nociceptive threshold to mechanical stimulation was utilized to examine the effects of an intraperitoneal injection of saline (0.1 mL/kg) or naloxone (1 mg/kg) on antinociception induced by a 20-minute period of 2-Hz or 100-Hz EA applied to the Zusanli (ST36) and Sanyinjiao (SP6) acupoints before surgical incision, or 10 minutes after or 100 minutes after surgical incision of the hind paw. The extent of mechanical hyperalgesia after the incision was significantly attenuated by the application of 100-Hz EA preoperatively, but not by its application at 10 minutes or 100 minutes postoperatively. By contrast, 2-Hz EA was effective against postoperative hyperalgesia when applied 10 minutes or 100 minutes after surgery but not when it was applied preoperatively. Only the effect of 2-Hz EA applied 10 minutes after surgery was sensitive to naloxone. The present study showed for the first time that 100-Hz EA, but not 2-Hz EA, exerts a nonopioidergic preemptive effect against postincision pain in rats. Copyright © 2016. Published by Elsevier B.V.

NIR-laser tissue welding in an in vivo guinea pig animal model

Near infrared laser tissue welding (LTW) is achieved by subjecting the closely approximated surgically incised tissues to a laser beam at a wavelength that is absorbed by water in the tissue. Full thickness welds are accomplished with optimum laser power and penetration depths appropriate for the thickness of welded tissues. No extrinsic cross-linking or bonding materials are used. The absorbed laser energy increases the entropy of collagen in the tissue. In LTW, tissue water temperatures transiently rises to approximately 60° C, causing partial denaturing of collagen and other structural proteins due to breaking of hydrogen bonds, electrostatic interactions and some interchain covalent bonds for a short duration of time. This is followed by cross linking of proteins on either side of weld line, with reformation of the above mentioned bonds as the tissue cools, resulting in the formation of water tight full thickness welds. In this study, a cw fiber laser emitting at 1455 nm, corresponding to absorption by a water vibrational overtone, is used for in vivo LTW of surgical incisions made in the skin of guinea pigs under general anesthesia. The tensile strength and healing rates of the welded incisions are compared to suturing of similar incisions. Laser parameters, including power, scanning rates, exposure area, and exposure duration, are optimized to reduce thermal damage while maintaining tensile strength.

Temperature-controlled tissue laser soldering is an innovative sutureless technique awaiting only solid experimental data to become the gold-standard surgical procedure for incision closure. The goals of the current study were: (1) to define the optimal laser soldering conditions, (2) to explore the immediate skin reparative healing events after sealing the wound, and (3) to determine the long-term trajectory of skin wound healing. Skin incisions were generated over rabbit dorsa and were closed using different wound-closure interventions, in three groups: (a) closure, using a temperature-controlled infrared fiberoptic CO2 laser system, employing 47% bovine serum albumin as a solder; (b) wound closure by cyanoacrylate glues; and (c) wound closure by sutures. The reparative outcomes were evaluated macroscopically and microscopically, employing semi-quantitative grading indices. Laser soldering of incisions at T = 65 degrees C emerged as the optimal method achieving immediate wound sealing. This in turn induced accelerated reparative events characterized by a reduced inflammatory reaction, followed by minimal scarring and leading to a fine quality healing. Temperature-controlled laser soldering offers an accelerated wound reparative process with numerous advantages over the conventional methods. Further investigations may reveal additional benefits in the spectrum of advantages that this innovative surgical technology has to offer. This can introduce new scientific insight that will pave the way for clinical use.

A comparison of obsidian and surgical steel scalpel wound healing in rats.

PubMed

Disa, J J; Vossoughi, J; Goldberg, N H

1993-10-01

There are several anecdotal clinical articles claiming wound healing and scar superiority using obsidian (volcanic glass) scalpels. In order to determine if skin incisions made with obsidian were superior to those made with standard surgical steel, wound tensile strength, scar width, and histology were assessed in 40 adult male Sprague-Dawley rats. Each rat received two parallel 8-cm dorsal skin incisions, one with an obsidian scalpel and the other with a surgical steel scalpel (no. 15 blade). Data were analyzed by ANOVA. Tensile strength of the two wound types was not different at 7, 14, 21, and 42 days. Scar width, however, was significantly less in the obsidian wounds at 7, 10, and 14 days (p < 0.005). At 21 days, scar width was not different in the two groups. At 42 days, all wounds were barely detectable, thus precluding scar width analysis. A blinded histologic review suggested that obsidian wounds contained fewer inflammatory cells and less granulation tissue at 7 days.

Femtosecond phacoemulsification: the business and the medicine.

PURPOSE FOR REVIEW: Phacoemulsification is the preferred method for cataract surgery in the developed world. The number of phacoemulsification procedures performed annually is expected to increase as the population ages. Femtosecond cataract surgery offers several surgical advantages over conventional phacoemulsification and has already attained commercial application in some countries. The purpose of this review is to outline the benefits, risks and commercial issues of femtosecond lasers as applied to cataract surgery. Cataract surgeons are adopting femtosecond technology to perform laser capsulotomy, lens fragmentation, clear cornea incisions and limbal relaxing incisions. Femtosecond lasers clearly perform these surgical steps with greater precision and reproducibility. Further benefits such as improved postoperative refractive results and reduced complication rates are being investigated. Commercial issues have invariably arisen such as cost of installation and operation, value proposition and return on investment. Femtosecond cataract surgery is an evolving procedure that can potentially lead to better and safer surgical outcomes. This review presents the currently available scientific evidence and discusses some of the relevant financial issues concerning this technology.

Postoperative ascitic leaks: the ongoing challenge.

1992-06-01

The leak of ascitic fluid from surgical incisions is thought to be associated with a very high mortality rate. There have been few reports, however, focusing on the clinical characteristics, management, or mortality rates of this condition. During a 10-year period, 18 patients with postoperative ascitic fluid leaks were treated. All patients had ascites before surgery and all had liver disease; in 13 of the 18 patients alcoholic liver disease was the cause of ascites. Ten of the 18 patients died (56%). Midline incisions were more often associated with recalcitrant leaks and fatal complications than were transverse incisions. Early consideration of fascial dehiscence and prompt repair is emphasized. The most effective predictor of survival was cessation of the leak.

The article provides data on clinical diagnosis (4 patients, 4 eyes) and early surgical treatment of corneal intralamellar abscesses (ICA) in the zone of corneo-scleral tunnel incision after phacoemulsification (PE). ICA developed via corneo-scleral incision was a relatively reliable biomicroscopic sign of the beginning chronic endophthalmitis. Despite of massive nonsurgical treatment (antibiotics, glucocorticoids, non-steroid anti-inflammatory agents etc.) inflammation was not arrested completely, it recurred within 2,5-6 months after PE. Reconstructive conjunctivo-sclerokeratoplasty resulted in arrest of inflammation and visual function recovery in 3 patients. In one patient this procedure was not possible to perform because of total loss of visual functions due to chronic endophthalmitis.

After decades on the margins of primary health care, surgical and anaesthesia care is gaining increasing priority within the global development arena. The 2015 publications of the Disease Control Priorities third edition on Essential Surgery and the Lancet Commission on Global Surgery created a compelling evidenced-based argument for the fundamental role of surgery and anaesthesia within cost-effective health systems strengthening global strategy. The launch of the Global Alliance for Surgical, Obstetric, Trauma, and Anaesthesia Care in 2015 has further coordinated efforts to build priority for surgical care and anaesthesia. These combined efforts culminated in the approval of a World Health Assembly resolution recognizing the role of surgical care and anaesthesia as part of universal health coverage. Momentum gained from these milestones highlights the need to identify consensus goals, targets and indicators to guide policy implementation and track progress at the national level. Through an open consultative process that incorporated input from stakeholders from around the globe, a global target calling for safe surgical and anaesthesia care for 80% of the world by 2030 was proposed. In order to achieve this target, we also propose 15 consensus indicators that build on existing surgical systems metrics and expand the ability to prioritize surgical systems strengthening around the world.

Congenital penile curvature: update and management.

PubMed

Makovey, Iryna; Higuchi, Ty T; Montague, Drogo K; Angermeier, Kenneth W; Wood, Hadley M

2012-08-01

Congenital penile curvature results from disproportionate development of the tunica albuginea of the corporal bodies and is not associated with urethral malformation. Patients usually present after reaching puberty as the curvature becomes more apparent with erections, and severe curvature can make intercourse difficult or impossible, at which point surgical repair is recommended. Excellent outcomes can be expected with surgical intervention. The three most commonly used repair techniques are the original Nesbit procedure, modified Nesbit procedure, and plication. Nesbit and modified Nesbit techniques require that an incision is made in the tunica albuginea while plication techniques utilize plicating sutures without an incision. While Nesbit and modified Nesbit techniques are more complex operations, these generally result in less recurrences and more satisfactory outcomes as opposed to the quicker and simpler plication technique.

Minimally invasive cardiac surgeries for aortic valve replacement (AVR) are still a technical challenge for surgeons because these procedures are undertaken through small incisions and deep surgical fields. Although AVR via vertical infraaxillary thoracotomy can be a cosmetically superior option, a disadvantage of this approach is the distance between the thoracotomy incision and the ascending aorta. Therefore, we devised a technique to perform all manipulations using the fingertips without the aid of a knot pusher or long-shafted surgical instruments. This was achieved by particular placement of several retracted sutures to the right chest wall. We named placement of these sutures the "Stonehenge technique." In conclusion, AVR via vertical infraaxillary thoracotomy with our Stonehenge technique can be safely and simply performed with superior cosmetic advantages.

We report two cases of penile fracture. Case 1 was in a 22-year-old male. He heard a cracking sound during urination and experienced acute penile pain and detumescence. He was admitted to our hospital on that day. Case 2 was in a 52-year-old male. He heard a cracking sound during sexual intercourse and experienced detumescence. He was admitted to our hospital on the next day. In both cases, magnetic resonance imaging (MRI) showed disruption of the tunica albuginea. We performed immediate surgical repair through localized incision. They had no perioperative complications. Several months after surgery, they reported subjectively good erection without penile curvature or pain. We found that MRI is a useful tool for the assessment of location of the tunica rupture and minimization of the surgical incision.

Objective The goal of this study was to evaluate the first formal counseling program for obstetric fistula patients in Eritrea. Methods To evaluate the impact of the counseling program, clients were interviewed both before pre-operative counseling and again after post-operative counseling. A questionnaire was used in the interviews to assess women's knowledge about fistula, self-esteem, and their behavioral intentions for health maintenance and social reintegration following surgical repair. In addition, two focus groups were conducted with a total of 19 clients assessing their experiences with the surgical care and counseling. Results Data from the questionnaires revealed significant improvements in women's knowledge about fistula, self-esteem, and behavioral intentions following counseling. Focus group data also supported increased knowledge and self-esteem. Conclusion Evaluation of the short-term impact of an initial formal counseling program for fistula patients in sub-Saharan Africa affirmed the positive effects that such a program has for fistula patients, with increased knowledge about the causes of fistula, fistula prevention and enhanced self-esteem. Practical implications Culturally appropriate counseling can be incorporated into services for surgical repair of obstetric fistula in low-resource settings and has the potential to improve the physical and mental well-being of women undergoing fistula repair.

Introduction: New technologies in dental practice, such as laser, have enabled new strategies to be established in dental education. The aim of this study was to analyze the difficulties that dental students encountered with performing surgical incisions using Er:YAG laser (LE), and the morphology of these incisions. Material and Methods: Sixteen undergraduate dental students and ten dental professionals (DP) enrolled at The Master of Science Program in Laser Dentistry were asked to perform 15 incisions using an LE and 15 with a conventional scalpel. The incisions were compared, based on the shape factor (relation between area and perimeter), which was obtained by a digital image system and by a morphometry software. Data was submitted to statistical analysis of variance (p 0.05). Results: Considering the incisions performed by scalpel, DP showed statistically significant differences (p < 0.01) in relation to control group (CG). Considering the LE, all groups showed significant differences (p<0.0001) in relation to CG, especially the DP group. The main laser technical failures were performing an incision that was not in a straight line, without defined borders, using an inconstant cutting speed, and absence of suction and water jet appliances. None of the groups performed adequate incisions using LE. Conclusion: Greater emphasis is required in relating laser therapy practice to the physical properties of laser, particularly for dental professionals that specialize in laser.

Efficacy of Single-Suture Incision Closures in Tagged Juvenile Chinook Salmon Exposed to Simulated Turbine Passage

Boyd, James W.; Deters, Katherine A.; Brown, Richard S.

2011-09-01

Reductions in the size of acoustic transmitters implanted in migrating juvenile salmonids have resulted in the use of a shorter incision-one that may warrant only a single suture for closure. However, it is not known whether a single suture will sufficiently hold the incision closed when fish are decompressed and when outward pressure is placed on the surgical site during turbine passage through hydroelectric dams. The objective of this study was to evaluate the effectiveness of single-suture incision closures on five response variables in juvenile Chinook salmon Oncorhynchus tshawytscha that were subjected to simulated turbine passage. An acoustic transmitter (0.43more » g in air) and a passive integrated transponder tag (0.10 g in air) were implanted in each fish; the 6-mm incisions were closed with either one suture or two sutures. After exposure to simulated turbine passage, none of the fish exhibited expulsion of transmitters. In addition, the percentage of fish with suture tearing, incision tearing, or mortal injury did not differ between treatments. Expulsion of viscera through the incision was higher among fish that received one suture (12%) than among fish that received two sutures (1%). The higher incidence of visceral expulsion through single-suture incisions warrants concern. Consequently, for cases in which tagged juvenile salmonidsmay be exposed to turbine passage, we do not recommend the use of one suture to close 6-mm incisions associated with acoustic transmitter implantation.« less

Contemporary training in obstetrics and gynecology is aimed at the acquisition of a complex set of skills oriented to both the technical and personal aspects of patient care. The ability to create clinical simulations through virtual reality (VR) may facilitate the accomplishment of these goals. The purpose of this paper is 2-fold: (1) to review the circumstances and equipment in industry, science, and education in which VR has been successfully applied, and (2) to explore the possible role of VR for training in obstetrics and gynecology and to suggest innovative and unique approaches to enhancing this training. Qualitative assessment of the literature describing successful applications of VR in industry, law enforcement, military, and medicine from 1995 to 2000. Articles were identified through a computer-based search using Medline, Current Contents, and cross referencing bibliographies of articles identified through the search. One hundred and fifty-four articles were reviewed. This review of contemporary literature suggests that VR has been successfully used to simulate person-to-person interactions for training in psychiatry and the social sciences in a variety of circumstances by using real-time simulations of personal interactions, and to launch 3-dimensional trainers for surgical simulation. These successful applications and simulations suggest that this technology may be helpful and should be evaluated as an educational modality in obstetrics and gynecology in two areas: (1) counseling in circumstances ranging from routine preoperative informed consent to intervention in more acute circumstances such as domestic violence or rape, and (2) training in basic and advanced surgical skills for both medical students and residents. Virtual reality is an untested, but potentially useful, modality for training in obstetrics and gynecology. On the basis of successful applications in other nonmedical and medical areas, VR may have a role in teaching essential elements of counseling and surgical skill acquisition.

Liss, S. A.; Ashton, N. K.; Brown, R. S.

A new acoustic transmitter (AT; cylindrical, 0.7 g in air, 24.2×5.0 mm, up to 365 d battery life) was developed to monitor age-0 sturgeon; however, an implantation technique is critical to provide guidance for its use in field research. The goal of this study was to evaluate four implantation techniques by assessing transmitter retention, survival, growth, and wound healing variables. White sturgeon (Acipenser transmontanus; n = 150, 35–116 g, 182–289 mm fork length) were separated into five treatments: 1) unmarked, 2) flank incision with one suture, 3) flank incision without a suture, 4) offline incision with one suture, and 5)more » offline incision without a suture. Tagged fish were implanted with a non-functioning AT and all fish were held for 28 days. There was 100% transmitter retention and no difference in survival or growth (by 14 d post-implantation) among treatments. Sutured treatments had greater inflammation and presence of ulceration and water mold than non-sutured. Offline incision fish were more susceptible to red vein aggregation than flank incision fish. Non-sutured treatments had greater openness than sutured, but only during the first 14 d post-implantation. The flank incision without a suture technique is recommended.« less

The effect of fellowship programs on resident training for gynecologic surgery volume has not been clearly defined. The purpose of our study is to assess resident surgical volume for laparoscopic and vaginal hysterectomy before and after initiation of a female pelvic medicine and reconstructive surgery (FPMRS) fellowship. A retrospective review of Accreditation Council for Graduate Medical Education Resident Case Logs of obstetrics and gynecology residents who graduated in the 3 years before and after initiation of a FPMRS fellowship was performed. Mean values of vaginal and laparoscopic hysterectomies were compared using two-tailed t-tests with statistical significance set at p < 0.05. Obstetrics and gynecology resident case logs at the Ronald Reagan University of California Los Angeles (UCLA) Medical Center were assessed. The UCLA Medical Center, located in Los Angeles, CA, is a tertiary referral center with a graduating class of 7 obstetrics and gynecology residents yearly. Obstetrics and gynecology residents who graduated from residency 3 years before and after imitation of a FPMRS fellowship were included. In the 3 years before the start of the fellowship, 20 residents graduated, whereas 21 residents graduated after the start of the fellowship. Residents who graduated in the 3 years after the start of the FPMRS fellowship, finished with 4.6 less vaginal hysterectomies compared with residents who graduated before the fellowship (p = 0.022). Residents who graduated in the 3 years after the start of the FPMRS fellowship finished with 3.2 more laparoscopic hysterectomies compared with residents who graduated before the fellowship although this was not significant (p = 0.25). Resident surgical volume was significantly decreased for vaginal hysterectomy after the initiation of a FPMRS fellowship, whereas laparoscopic hysterectomy volume was not significantly changed. Longer follow-up and a national assessment are necessary to determine the broader effect of fellowship training on resident surgical experience.

Patients with closed high-energy injuries associated with major trauma have surprisingly high rates of surgical site infection in incisions created during fracture fixation. One factor that may reduce the risk of surgical site infection is the type of dressing applied over the closed surgical incision. In this multicentre randomised clinical trial, negative-pressure wound therapy will be compared with standard dressings with outcomes of deep infection, quality of life, pain and disability. Adult patients presenting to hospital within 72 hours of sustaining major trauma, requiring a surgical incision to treat a fractured lower limb, are eligible for inclusion. Randomisation, stratified by trial centre, open/closed fracture at presentation and Injury Severity Score (ISS) ≤15 versus ISS ≥16 will be administered via a secure web-based service using minimisation. The random allocation will be to either standard wound management or negative-pressure wound therapy.Trial participants will usually have clinical follow-up at the local fracture clinic for a minimum of 6 months, as per standard National Health Service practice. Diagnosis of deep infection will be recorded at 30 days. Functional, pain and quality of life outcome data will be collected using the Disability Rating Index, Douleur Neuropathique Questionnaire and Euroqol - 5 Dimension - 5 level (EQ-5D-5L) questionnaires at 3 months and 6 months postinjury. Further data will be captured on resource use and any late postoperative complications.Longer term outcomes will be assessed annually for 5 years and reported separately. National Research Ethics Committee approved this study on 16 February 2016 16/WM/0006.The National Institute for Health Research Health Technology Assessment monograph and a manuscript to a peer-reviewed journal will be submitted on completion of this trial. The results of this trial will inform clinical practice on the clinical and cost-effectiveness of the treatment of this injury.

Evaluating the Analgesic Effect of the GLS Inhibitor 6-Diazo-5-Oxo-L-Norleucine in Vivo

PubMed Central

Crosby, Heith A; Miller, Kenneth E

2018-01-01

Glutamate is an excitatory neurotransmitter, produced by its synthetic enzyme, glutaminase (GLS), and packaged by vesicular transporters (VGluT2) into synaptic vesicles. Primary sensory peripheral nerve and spinal synaptic terminals release glutamate during nociceptive (pain) signaling. In post-incisional and inflammation models in rats, GLS and VGluT2 production is elevated in dorsal root ganglion neuronal cell bodies and transported to peripheral and spinal terminals for increased glutamate synthesis and release. 6-Diazo-5-oxo-l-norleucine (DON) is a GLS inhibitor that produces long lasting pain relief when applied to the inflamed paw of arthritic rats, but its effect in a post-incisional model has not been evaluated. In this study, we examined the analgesic efficacy of DON in a surgical incision model by measuring thermal latency and mechanical allodynia. Following behavioral evaluation, we examined the skin for VGluT2, GLS and glutamate immunoreactivity (ir). Our findings revealed that VGluT2-ir is elevated in the stratum lucidum by approximately 19%, 64 hours post-surgical incision and attenuated by approximately 5.4% after the administration of DON. During that same period GLS-ir was elevated in dermal nerve fibers by 52% and was attenuated by approximately 27.9% after the application of DON. Additionally, glutamate-ir was elevated in epidermal nerve fibers by 35% after incision and attenuated by approximately 23% after the administration of DON. Behavioral testing 24 and 48 hours after a single local administration of DON showed five out of six animals having an analgesic response to mechanical allodynia, but not to thermal hyperalgesia. Following a surgical incision, the area of injury shows increased VGluT2-, GLS-, glutamate-ir, mechanical allodynia and no change in thermal latency. After the application of the GLS inhibitor, DON, nerve fiber of the skin showed decreased VGluT2, GLS, and glutamate-ir. Furthermore, post-incision DON treated animals exhibited decreased mechanical allodynia with no change in thermal latency when compared to control animals. PMID:29888760

To evaluate the clinical and optical outcomes after clear corneal incision cataract surgery (CICS) with three different incision sizes (1.8, 2.0 and 3.0 mm). Eyes of 150 patients with age-related cataract scheduled for coaxial cataract surgery were randomized to three groups: 1.8, 2.0, or 3.0 mm CICS. Intraoperative data and postoperative outcomes including surgically induced astigmatism (SIA), the corneal incision thickness, wavefront aberrations and modulation transfer function (MTF) of cornea were obtained. There were no significant differences among the three groups in demographic characteristics and intraoperative outcome. The 1.8 and 2.0 mm microincisions showed more satisfactory clinical outcomes than the 3.0 mm incision. The 1.8 mm incision showed significantly less SIA than the 2.0 mm incision until postoperative 1mo (P<0.05), but the difference was only 0.14-0.18 D. Combined with less increased incision thickness only at postoperative 1d (P=0.013), the 1.8 mm incision presented better uncorrected distance visual acuity (UCDVA) than the 2.0 mm incision only at 1d postoperatively (P=0.008). For higher-order aberrations and other Zernike coefficients, there were no significant differences between the 1.8 mm group and 2.0 mm group (P>0.05). Converting from 3.0 mm CICS to 1.8 or 2.0 mm CICS result in better clinical and optical outcomes. However, when incision is 1.8 mm, the benefits from further reduction in size compared with 2.0 mm are limited. The necessity to reduce the incision size is to be deliberated.

Background: Transumbilical single incision laparoscopic surgery (SILS) offers excellent cosmetic results and may be associated with decreased postoperative pain, reduced need for analgesia, and thus accelerated recovery. Herein, we report the first transumbilical single incision laparoscopic pancreatectomy case in a patient who had renal cell cancer metastasis on her pancreatic corpus and tail. Methods: A 59-year-old female who had metastatic lesions on her pancreas underwent laparoscopic subtotal pancreatectomy through a 2-cm umbilical incision. Results: Single incision pancreatectomy was performed with a special port (SILS port) and articulated equipment. The procedure lasted 330 minutes. Estimated blood loss was 100mL. No perioperative complications occurred. The patient was discharged on the seventh postoperative day with a low-volume (20mL/day) pancreatic fistula that ceased spontaneously. Pathology result of the specimen was renal cell cancer metastases. Conclusion: This is the first reported SILS pancreatectomy case, demonstrating that even advanced surgical procedures can be performed using the SILS technique in well-experienced centers. Transumbilical single incision laparoscopic pancreatectomy is feasible and can be performed safely in experienced centers. SILS may improve cosmetic results and allow accelerated recovery for patients even with malignancy requiring advanced laparoscopic interventions. PMID:21605524

Surgically induced astigmatism (SIA) was one of the factors that influences the desirable refractive outcome, and it was related to the length, type, location, structure of the incision and to the suture closure technique, etc. The aim was to evaluate the association of corneal histocytological changes with SIA after phacoemulsification. The study enrolled 68 cases of cataract patient (68 eyes). Corneal histocytological parameters at corneal incision, central cornea and contralateral incision obtained by confocal microscope through focusing (CMTF) were compared preoperatively and 1 week, 2 weeks, 1 month, 3 months and 6 months postoperatively. These biometric parameters included the endothelial cell density, keratocyte density of posterior stromal layer, and the morphological changes. SIA was calculated by Jaffe's vector analysis. 1 From preoperatively to 1 week, 2 weeks, 1 month, 3 months and 6 months postoperatively, the endothelail cell density was decreased significantly (p < 0.05). Keratocyte density of posterior stroma layer was increased significantly only at 1 week, 2 weeks, 1 month, 3 months postoperatively (p <0.05), but not statistically significant (p = 0.173) at 6 months postoperatively compared to preoperative values. 2 The histocytological observations indicated that the morphology changed significantly postoperatively at the corneal incision, including the cell absent area, wave-like area, dot-like and mass-like hyperreflection, stripe-like absent area, in the endothelial layer, and the keratocyte activation, microfolds, irregular hyporeflective or hyperreflective belt, and a little dot-like hyperreflection in the posterior stroma layer. 3 The reduction of the endothelial cell density at the corneal incision at 1 week, 2 weeks, 1 month postoperatively, were positively correlated with SIA (P1 week = 0.003, P2 weeks = 0.003, P1 month = 0.032), while others were not associated with SIA statistically. The reduction of endothelail cell density and the histocytological changes at the corneal incision were associated with SIA. The underlining mechanism needs further study.

Excision and Patch Grafting of a Lateral Peyronie’s Plaque—Utilizing a Longitudinal “Window” Approach

PubMed Central

Lue, Kathy; Emtage, Justin B; Martinez, Daniel R; Yang, Christopher; Carrion, Rafael

2015-01-01

Introduction Peyronie’s disease (PD) is a debilitating disorder in which collagen deposition, fibrosis, and plaques in the tunica albuginea result in penile curvature, shortening, and pain. For severe curvatures requiring plaque incision or excision with grafting (PIEG), a subcoronal circumcising incision with penile degloving has historically been used. Aims The aim of this study was to report our unique approach to PIEG via a longitudinal “window” incision for the correction of PD, minimizing the surgical manipulation and dissection accompanying the traditional circumcising incisional approach that may lead to increased postoperative edema, pain, and prolonged healing time. Methods A patient presented with a stable, painless, 90-degree midshaft leftward curvature causing penetration difficulties and painful intercourse for his partner. His Sexual Health Inventory for Men (SHIM) score was 23. The patient opted for surgical correction with plaque excision and grafting via a 4-cm longitudinal incision overlying the point of maximal curvature along the left lateral penile shaft. This direct access to the left corpus cavernosum and plaque, along with dissecting skin, dartos, and Buck’s fascia, created a window with sufficient exposure for excision and patch grafting. Main Outcome Measures The main outcome measures were objective data and subjective data in men undergoing PIEG via lateral longitudinal “window” incision for PD repair. Results The plaque was excised and a porcine small intestinal submucosa graft was sewn in. Intraoperative artificial tumescence at the end of surgery revealed complete correction of the curvature. The patient experienced painless rigid erections by postoperative day three with minimal penile edema. By postoperative week four, he could successfully partake in coitus. His SHIM score remained unchanged. At maximum follow-up 6 months postoperatively, he still endorsed excellent cosmetic and functional outcomes with spontaneous unassisted erections and no recurrence of his curvature. Conclusion A lateral longitudinal incision for PIEG is a feasible technique and may reduce the postoperative morbidity and dissection required with traditional circumcising incision with penile degloving. Larger comparative studies are necessary for further evaluation. PMID:26185673

To assess the surgically induced corneal astigmatism (SIA) introduced by femtosecond laser-assisted clear corneal incisions (CCIs) for cataract extraction and to compare it with the SIA of manually created CCIs. Bascom Palmer Eye Institute, Miller School of Medicine, Miami, Florida, USA. Prospective nonrandomized comparative case series. Eyes received femtosecond laser-assisted CCIs (Group 1) or manual CCIs (Group 2). The surgical plan included 1 primary and 1 secondary port; the sites of the incisions were the same in both groups and were diametrically opposed between the right eye and left eye. The SIA was assessed using the preoperative and 1-month postoperative keratometric values obtained from corneal topography examinations. This study included 72 eyes of 68 patients with a mean age of 69.0 years ± 9.87 (SD) (range 36 to 90 years). Thirty-six eyes received femtosecond laser-assisted CCIs (Group 1) and 36 received manual CCIs (Group 2). The mean preoperative topographic corneal astigmatism was -1.19 ± 0.68 diopters (D) (range 0 to 2.50 D) and -0.92 ± 0.63 D (range 0.10 to 2.45 D) for Group 1 and Group 2, respectively, whereas, 1 month after cataract surgery, it was -1.16 ± 0.63 D (range 0.20 to 2.57 D) and -0.95 ± 0.64 D (range 0.21 to 2.37 D), respectively. Multivariate vector analysis revealed no statistically significant difference between the 2 groups for preoperative astigmatism, postoperative astigmatism, and SIA (P > .05 for all comparisons between Group 1 and Group 2). Femtosecond laser-assisted and manual corneal incisions for cataract surgery did not appear to significantly alter corneal astigmatism, whereas they showed comparable SIA. Drs.

To describe a technique of surgical peripheral iridectomy via a clear-cornea tunnel incision to prevent or treat pupillary block following phacoemulsification. Description of technique and retrospective description results in 20 eyes of 20 patients with acute angle closure with coexisting visually significant cataract undergoing phacoemulsification considered at risk of postoperative papillary block as well as two pseudo-phakic eyes with acute postoperative pupillary-block. Following phacoemulsification and insertion of an intraocular lens, a needle with a bent tip was inserted behind the iris through the corneal tunnel incision. A blunt iris repositor was introduced through the paracentesis and placed above the iris to exert posterior pressure and create a puncture. The size of the puncture was enlarged using scissors. For postoperative pupillary block the same technique was carried out through the existing incisions created for phacoemulsification. Peripheral iridectomy was successfully created in all 22 eyes. At a mean follow-up of 18.77 ± 9.72 months, none of the iridectomies closed or required enlargement. Two eyes had mild intraoperative bleeding and one eye a small Descemet's detachment that did not require intervention. No clinically significant complications were observed. Visual acuity and IOP improved or was maintained in all patients. The incidence of pupillary block in our hospital was 0.09% overall, 0.6% in diabetics and 3.5% in those with diabetic retinopathy. This technique of peripheral iridectomy via the cornea tunnel incision can be safely used during phacoemulsification in eyes at high risk of pupillary block or in the treatment of acute postoperative pupillary-block after cataract surgery. The technique is likely to be especially useful in brown iris, or if a laser is not available.

Perioperative analgesia during thoracotomy is often achieved by combining paravertebral block (PVB) with general anesthesia (GA). Functional near-infrared spectroscopy (NIRS) can detect changes in cerebral oxygenation resulting from nociceptive stimuli in the awake state or under sedation. We used NIRS to measure changes in cerebral blood flow provoked by thoracotomy incision made under GA and determine how these changes were influenced by supplementation of GA with PVB. Thirty-four patients undergoing elective thoracotomy were enrolled. Patients were randomly assigned to a group receiving only GA, or GA combined with PVB (GA + PVB). Changes in cerebral oxygenated hemoglobin (ΔO 2 Hb), deoxygenated-Hb (ΔHHb), and total-Hb (ΔtotalHb) were evaluated by NIRS as surgery began. In the GA group, ΔO 2 Hb was significantly higher in the hemisphere contralateral to the side of surgery when the incision was made and 2 min after incision compared with the ipsilateral side (start of surgery, P < 0.01; 2 min, P < 0.05). In contrast, there were no significant changes in the ΔO 2 Hb at any of the time points in the GA + PVB group. Comparable with ΔO 2 Hb, the concentration of ΔtotalHb was significantly higher in the contralateral hemisphere in the GA group at the start of surgery (P < 0.05). Changes in the cerebral O 2 Hb concentration were detected by NIRS immediately after surgical incision under GA, but not in the presence of a PNB. NIRS could be used to monitor surgical pain. PVB inhibited changes in oxygenation induced by incision-provoked pain.

PubMed

Vilar-Compte, Diana; García-Pasquel, María José

2011-01-01

The effectiveness of perioperative antibiotic prophylaxis in reducing surgical site infections has been demonstrated. Its utility is recognized for clean-contaminated procedures and some clean surgeries. Prophylactic antibiotics are used as intended to cover the most common germs in the surgical site; first and second generation cephalosporins are the most used. For optimal prophylaxis, an antibiotic with a targeted spectrum should be administered at sufficiently high concentrations in serum, tissue, and the surgical wound during the time that the incision is open and risk of bacterial contamination. The infusion of the first dose of antimicrobial should begin within 60 min before surgical incision and should be discontinued within 24 h after the end of surgery The prolonged use of antibiotic prophylaxis leads to emergence of bacterial resistance and high costs. The principles of antimicrobial prophylaxis in cancer surgery are the same as those described for general surgery; it is recommended to follow and comply with the standard criteria. In mastectomies and clean head and neck surgery there are specific recommendations that differ from non-cancer surgery. In the case of very extensive surgeries, such as pelvic surgery or bone surgery with reconstruction, extension of antibiotics for 48-72 h should be considered.

The antimicrobial and anti-inflammatory activity of honey and its ability to accelerate wound healing make it an attractive option in surgical wound care. We performed a randomized clinical trial to compare the efficacy of honey dressing with conventional dressing regarding the aesthetic outcome. Bilateral symmetric incisions in randomly selected plastic surgical patients were randomly covered postoperatively with conventional dressing and honey dressing for five days. The aesthetic outcome of the two sides was rated on a Visual Analog Scale by the surgeon and the patient and compared at month three and six after surgery. Seventy two symmetrical incisions in 52 patients were evaluated during the study. The mean width of the scar after the third and the sixth month was 3.64 +/- 0.83 mm and 3.49 +/- 0.87 mm on the side that received honey dressing and 5.43 +/- 0.05 mm and 5.30+/- 1.35 mm in the control group. Wilcoxon signed-rank test showed significant difference between honey and conventional dressing outcomes at third and sixth month (p < 0.001). The healing process of the surgical wound and its final aesthetic result could be improved by using honey dressing. © 2016 S. Karger GmbH, Freiburg.

The aim of this randomized, controlled, clinical study was to compare two surgical techniques with the acellular dermal matrix graft (ADMG) to evaluate which technique could provide better root coverage. Fifteen patients with bilateral Miller Class I gingival recession areas were selected. In each patient, one recession area was randomly assigned to the control group, while the contra-lateral recession area was assigned to the test group. The ADMG was used in both groups. The control group was treated with a broader flap and vertical-releasing incisions, and the test group was treated with the proposed surgical technique, without releasing incisions. The clinical parameters evaluated before the surgeries and after 12 months were: gingival recession height, probing depth, relative clinical attachment level and the width and thickness of keratinized tissue. There were no statistically significant differences between the groups for all parameters at baseline. After 12 months, there was a statistically significant reduction in recession height in both groups, and there was no statistically significant difference between the techniques with regard to root coverage. Both surgical techniques provided significant reduction in gingival recession height after 12 months, and similar results in relation to root coverage.

Results of surgical treatment of 61 patients with injuries of the duodenum are analyzed. The causes of injuries were stab-incised wounds in 24 patients, missile wound -- in 7, closed abdominal trauma -- in 26, trauma of the duodenum during endoscopic papillosphincterotomy -- in 4. All the patients underwent surgery. Complications were seen in 32 (52.5%) patients, 21 patients died, lethality was 34.4%. Within the first 24 hours since the trauma 7 patients died due to severe combined trauma, blood loss, 54 patients survived acute period of trauma, including 28 patients after open trauma, 26 -- after closed and 4 -- after trauma of the duodenum during endoscopic papillosphincterotomy. Diagnostic and surgical policies are discussed. Results of treatment depending on kind and time of surgery are regarded. It is demonstrated that purulent complications due to retroperitoneal phlegmona, traumatic pancreatitis, pneumonia are the causes of significant number of unfavorable outcomes. Therefore, it is important to adequately incise and drainage infected parts of retroperitoneal fat tissue with two-lumen drainages. Decompression through duodenal tube is the effective procedure for prophylaxis of suture insufficiency and traumatic pancreatitis. Suppression of pancreatic and duodenal secretion with octreotid improves significantly surgical treatment results.

A retrospective analysis of temporomandibular joint ankylosis patients (n = 15), who underwent interpositional arthroplasty or Matthews device arthroplasty, was conducted. The surgical outcomes (preoperative, recent [4-6 weeks], intermediate [1 year], and late [3 years] postoperative maximal incisal opening, hospital stay, and complication, relapse, and reoperation rates) were compared. Significant (all p < 0.05) differences were recorded in temporomandibular joint ankylosis patients treated with interpositional arthroplasty with autogenous tissue (53.3%) versus Matthews device arthroplasty (46.7%) according to intermediate (25 ± 7 vs. 34 ± 5 mm) and late (19 ± 8 vs. 33 ± 5 mm) postoperative maximal incisal opening, intermediate (31% vs. 7%) and late (47% vs. 12%) postoperative relapse, and reoperation rate (38% vs. 0%). There was similarity (all p > 0.05) in preoperative (4.8 ± 2.9 vs. 4.9 ± 2.9 mm) and recent (35 ± 4 vs. 37 ± 4 mm) postoperative maximal incisal opening, hospital stay (3.5 ± 0.8 vs. 3.6 ± 0.8 days), and surgery-related complications (13% vs. 14%). Both surgical procedures evaluated were successful in initial management of temporomandibular joint ankylosis, but the Matthews device arthroplasty avoided postoperative relapse.

To report the clinical characteristics of 14 patients with imperforate hymen and their levels of tumor markers (CA 19-9 and CA 125). Fourteen patients with imperforate hymen who followed-up between September 2006 and September 2010 in the Department of Obstetrics and Gynecology, Dicle University School of Medicine, Diyarbakir, Turkey, were evaluated retrospectively. The clinical features and the management of the patients are discussed. The mean age of the patients was 13.8 years. All patients had primary amenorrhea and pelvic pain. The most common clinical symptoms were cryptomenorrhea in 14 patients, pelvic pain in 11, palpable abdominal mass in 6, voiding difficulties in 7, and defecation problems in 2. In 6 patients with palpable pelvic mass, the mean + standard deviation values of tumor markers were as follows: CA 125, 84.0 +/- 23.7 and CA 19-9, 162 +/- 189. One week after surgery we measured CA 125 and CA 19-9 levels once again. The postoperative mean CA 125 level was 13.8 +/- 3.6, and the mean postoperative CA 19-9 level was 17.5 +/- 3.5. Preoperative levels of CA 125 and CA 19-9 were significantly higher than those of the postoperative period (p < 0.001 for both comparisons). Six patients were treated by T-shaped incision and 8 patients by a central surgical incision through the hymenal membrane. Diagnosis of imperforate hymen is very important before undergoing surgery in a different clinic. Many patients have seen several doctors before receiving a clear diagnosis and have had tumor markers evaluated because the presence of pelvic mass in patients suggests the possibility of a gynecologic malignancy. Imperforate hymen is one of the benign conditions that increase serum CA 125 and CA 19-9 levels and which is not listed in the classical medical textbooks. These markers are not needed for the diagnosis.

From the beginning of the world assisting during childbirth was and is the women's domain. On the evolution this profession composed of many famous midwifes. Into this group unquestionably we can count Justine Siegemundin (1636-1705), midwife-self-taught person. Her activity contributed to rise the obstetrics knowledge in XVII century. Justine Siegemundin, the midwife of the Brandenburg court, published in 1690 a book describing a surgical trick still bears her name today. It is called the "double hold"--"Gedoppelter Handgriff", or "Siegemundin-Handgriff". This book counts as on the most important milestones of obstetrics history.

This study aims to assess the quality of various steps of manual small incision cataract surgery and predictors of quality, using video recordings. This paper applies a retrospective study. Fifty-two trainees participated in a hands-on small incision cataract surgery training programme at rural Chinese hospitals. Trainees provided one video each recorded by a tripod-mounted digital recorder after completing a one-week theoretical course and hands-on training monitored by expert trainers. Videos were graded by two different experts, using a 4-point scale developed by the International Council of Ophthalmology for each of 12 surgical steps and six global factors. Grades ranged from 2 (worst) to 5 (best), with a score of 0 if the step was performed by trainers. Mean score for the performance of each cataract surgical step rated by trainers. Videos and data were available for 49/52 trainees (94.2%, median age 38 years, 16.3% women and 77.5% completing > 50 training cases). The majority (53.1%, 26/49) had performed ≤ 50 cataract surgeries prior to training. Kappa was 0.57∼0.98 for the steps (mean 0.85). Poorest-rated steps were draping the surgical field (mean ± standard deviation = 3.27 ± 0.78), hydro-dissection (3.88 ± 1.22) and wound closure (3.92 ± 1.03), and top-rated steps were insertion of viscoelastic (4.96 ± 0.20) and anterior chamber entry (4.69 ± 0.74). In linear regression models, higher total score was associated with younger age (P = 0.015) and having performed >50 independent manual small incision cases (P = 0.039). More training should be given to preoperative draping, which is poorly performed and crucial in preventing infection. Surgical experience improves ratings. © 2015 Royal Australian and New Zealand College of Ophthalmologists.

Intra-Operative Surgical Irrigation of the Surgical Incision: What Does the Future Hold-Saline, Antibiotic Agents, or Antiseptic Agents?

Intra-operative surgical site irrigation (lavage) is common practice in surgical procedures in general, with all disciplines advocating some form of irrigation before incision closure. This practice, however, has been neither standardized nor is there compelling evidence that it effectively reduces the risk of surgical site infection (SSI). This narrative review addresses the laboratory and clinical evidence that is available to support the practice of irrigation of the abdominal cavity and superficial/deep incisional tissues, using specific irrigation solutions at the end of an operative procedure to reduce the microbial burden at wound closure. Review of PubMed and OVID for pertinent, scientific, and clinical publications in the English language was performed. Incision irrigation was found to afford a three-fold benefit: First, to hydrate the bed; second, to assist in allowing better examination of the area immediately before closure; and finally, by removing superficial and deep incisional contamination and lowering the bioburden, expedite the healing process. The clinical practice of intra-operative peritoneal lavage is highly variable and is dependent solely on surgeon preference. By contrast, intra-operative irrigation after device-related procedures has become a standard of care for the prophylaxis of acute peri-prosthetic infection. The clinical evidence that supports the use of antibiotic irrigation is limited and based on retrospective analysis and few acceptable randomized controlled trials. The results of laboratory and animal studies using aqueous 0.05% chlorhexidine gluconate are favorable, suggesting that further studies are justified to determine its clinical efficacy. The adoption of appropriate and standardized intra-operative irrigation practices into peri-operative care bundles, which include other evidence-based strategies (weight-based antimicrobial prophylaxis, antimicrobial sutures, maintenance of normothermia, and glycemic control), offers an inexpensive and effective method to reduce the risk of post-operative SSI and deserves further evaluation.

To study the influence of high-frequency electric surgical knives on healing of abdominal incision. Two hundred and forty white rats were divided into 10(0), 10(2), 10(5), and 10(8) groups and rat models of abdominal operation were induced by using electric surgical knives and common lancets respectively. Then they were respectively given hypodermic injections of normal saline and 0.2 mL quantitative mixture of Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa at a concentration of 10(2), 10(5) and 10(8). On the basis of the animal experiment, 220 patients undergoing abdominal operations (above type II) were randomly allocated into one of following three groups: electric knife (EK, 93 cases), electro-coagulation (EC, 55 cases) and control (72 cases). High-frequency electric surgical knives were used to dissect abdominal tissues and electro-coagulation for hemostasis in EK group. Common lancets and electro-coagulation were applied in EC group. Common lancets and tying silk suture were used in the controls. In all the groups except group 10(0), infection rate of incisional wounds made by electric surgical knives were remarkably higher than that with common lancets. Furthermore, there were significant differences in groups 10(2), 10(5), and 10(8) (P<0.05), but not in group 10(0) (P>0.05) between EK and EC groups. Clinical studies showed a delayed wound healing in 16 cases (17.20%) in EK, 11 cases (16.36%) in EC and 2 cases (2.86%) in the control groups. A significant difference between EK and the control groups (chi2 = 8.57, P<0.01), and between EC and the control groups (chi2 = 5.66, P<0.05) was observed, but not between EK and EC (chi2 = 0.017, P>0.05). High-frequency electric knives may remarkably delay abdominal incision healing. Its application should be minimized so as to reduce the possibility of postoperative complications.

The authors describe a surgical technique alternative to traditional pre-surgical orthodontics in order to increase the apical base in mandibular retrusion (class II, division I). This subapical osteotomy, optimizing inferior incisal axis without dental extractions and a long orthodontic treatment, associated to genioplasty permits to obtain an ideal labio-dento-mental morphology. This procedure avoids in some cases the need of a mandibular advancement and, if necessary, it reduces his entity with obvious advantages.

Cervical necrotizing fasciitis secondary to epiglottitis is rare. The standard treatment of this severe condition has long been early and aggressive surgical debridement and adequate antimicrobial therapy. We report the case of an immunocompetent 59-year-old man who developed cervical necrotizing fasciitis as a complication of acute epiglottitis. We were able to successfully manage this patient with conservative surgical treatment (incision and drainage, in addition to antibiotic therapy) that did not involve aggressive debridement.

Objectives Obstetric fistula is a maternal injury that causes uncontrollable leaking of urine or stool, and most women who develop it live in poverty in low-income countries. Obstetric fistula is associated with high rates of stigma and psychological morbidity, but there is uncertainty about the impact of surgical treatment on psychological outcomes. The objective of this exploratory study was to examine changes in psychological symptoms following surgical fistula repair, discharge and reintegration home. Methods Women admitted for surgical repair of obstetric fistula were recruited from a Tanzanian hospital serving a rural catchment area. Psychological symptoms and social functioning were assessed prior to surgery. Approximately 3 months after discharge, a data collector visited the patients' homes to repeat psychosocial measures and assess self-reported incontinence. Baseline to follow-up differences were measured with paired t tests controlling for multiple comparisons. Associations between psychological outcomes and leaking were assessed with t tests and Pearson correlations. Results Participants (N = 28) had been living with fistula for an average of 11 years. Baseline psychological distress was high, and decreased significantly at follow-up. Participants who self-reported continued incontinence at follow-up endorsed significantly higher PTSD and depression symptoms than those who reported being cured, and severity of leaking was associated with psychological distress. Conclusions Fistula patients experience improvements in mental health at 3 months after discharge, but these improvements are curtailed when women experience residual leaking. Given the rate of stress incontinence following surgery, it is important to prepare fistula patients for the possibility of incomplete cure and help them develop appropriate coping strategies.

Minimally invasive cardiac surgeries for aortic valve replacement (AVR) are still a technical challenge for surgeons because these procedures are undertaken through small incisions and deep surgical fields. Although AVR via vertical infraaxillary thoracotomy can be a cosmetically superior option, a disadvantage of this approach is the distance between the thoracotomy incision and the ascending aorta. Therefore, we devised a technique to perform all manipulations using the fingertips without the aid of a knot pusher or long-shafted surgical instruments. This was achieved by particular placement of several retracted sutures to the right chest wall. We named placement of these sutures the “Stonehenge technique.” In conclusion, AVR via vertical infraaxillary thoracotomy with our Stonehenge technique can be safely and simply performed with superior cosmetic advantages.

Frake, Paul C; Goodman, Joseph F; Joshi, Arjun S

2015-01-01

The investigators of this study hypothesized that fractures of the mandibular condyle can be repaired using short-segment intramedullary implants and purely endoscopic surgical technique, using a basic science, human cadaver model in an academic center. Endoscopic instrumentation was used through a transoral mucosal incision to place intramedullary implants of 2 cm in length into osteotomized mandibular condyles. The surgical maneuvers that required to insert these implants, including condyle positioning, reaming, implant insertion, and seating of the mandibular ramus, are described herein. Primary outcome was considered as successful completion of the procedure. Ten cadaveric mandibular condyles were successfully repaired with rigid intramedullary internal fixation without the use of external incisions. Both insertion of a peg-type implant and screwing a threaded implant into the condylar head were possible. The inferior portion of the implant remained exposed, and the ramus of the mandible was manipulated into position on the implant using retraction at the sigmoid notch. The results of this study suggest that purely endoscopic repair of fractures of the mandibular condyle is possible by using short-segment intramedullary titanium implants and a transoral endoscopic approach without the need for facial incisions or punctures. The biomechanical advantages of these intramedullary implants, including improved strength and resistance to mechanical failure compared with miniplates, have been recently established. The combination of improved implant design and purely endoscopic technique may allow for improved fixation and reduced surgical- and implant-related morbidity in the treatment of condylar fractures.

More aesthetically acceptable treatment options have been sought to minimise the morbidity associated with open surgery for gynaecomastia. This study investigated the use of a vacuum-assisted biopsy device (VABD) and liposuction to provide minimally invasive approach. Patients diagnosed with idiopathic benign gynaecomastia referred to the Breast Care Unit of Castle Hill Hospital between June 2002 and April 2007 and requesting surgical intervention underwent VABD excision and liposuction. All patients underwent thorough investigations to exclude any underlying cause for their gynaecomastia. The procedure was carried out by a single consultant surgeon with special interest in breast surgery. An 8-G mammotome probe was advanced through a 4-mm incision positioned in the corresponding anterior axillary line to excise the glandular disc. Liposuction was performed through the same incision. Incision wounds were closed with Steristrips. A pressure dressing was applied over wound by corset and an inflatable device. Thirty-six male patients with grade I and II gynaecomastia were recruited (22 bilateral, 14 unilateral). Average age was 33.3 years (range, 16-88 years). All underwent mammotome excision and liposuction. There were no conversions to an open procedure. The average procedure time was 50.3 min (range, 30-80 min). One intra-operative complication was recorded. The minimum follow-up time was 2 months. Thirty-four patients reported excellent satisfaction, two patients had residual gynaecomastia and needed a re-do procedure. Three patients developed small haematomas that resolved spontaneously. This novel, minimally invasive, surgical approach for gynaecomastia gives excellent results with minimal morbidity.

To investigate the therapeutic effectiveness of colonic exclusion and combined therapy for refractory constipation. Thirty-two patients with refractory constipation were randomly divided into treatment group (n = 14) and control group (n = 18). Fourteen patients in treatment group underwent colonic exclusion and end-to-side colorectal anastomosis. Eighteen patients in control group received subtotal colectomy and end-to-end colorectal anastomosis. The therapeutic effects of the operations were assessed by comparing the surgical time, incision length, volume of blood losses, hospital stay, recovery rate and complication incidence. All patients received long-term follow-up. All operations were successful and patients recovered fully after the operations. In comparison of treatment group and control group, the surgical time (h), incision length (cm), volume of blood losses (mL), hospital stay (d) were 87 +/- 16 min vs 194 +/- 23 min (t = 9.85), 10.4 +/- 0.5 cm vs 21.2 +/- 1.8 cm (t = 14.26), 79.5 +/- 31.3 mL vs 286.3 +/- 49.2 mL (t = 17.24), and 11.8 +/- 2.4 d vs 18.6 +/- 2.6 d (t = 6.91), respectively (P < 0.001 for all). The recovery rate and complication incidence were 85.7% vs 88.9% (P = 0.14 > 0.05), 21.4% vs 33.3% (P = 0.73 > 0.05), respectively. Colonic exclusion has better therapeutic efficacy on refractory constipation. It has many advantages such as shorter surgical time, smaller incision, fewer blood losses and shorter hospital stay.

Eight clinically healthy, adult male dogs, weighing 20 kg were used. All dogs were initially sedated by acepromazine. Thirty minutes later, ketamine plus xylazine was used to induce anesthesia. Surgical incision of laparotomy was done. After a 5 min manipulation of the abdominal organs, the incision was sutured. Vital signs including heart rate, respiratory rate and rectal temperature (RT) were recorded at the times of -30: premedication, 0: induction and Surgical incision, 30: End of surgery, 60, 90 and 120 min. Blood was sampled at the above mentioned times and analyzed using a commercial ELISA kit for cortisol. A significant decreasing trend in RT was observed during the studied times. No significant changes were observed in heart rate and respiratory rate (p>0.05), except at the time of 60 respiratory rate significantly decreased when compared to the time of 90 (p=0.026) and 120 (p=0.041). A non-significant but increasing trend in plasma levels of cortisol was observed.

The healing process in guinea pig skin following surgical incisions was evaluated at the molecular level, in vivo, by the use of Raman spectroscopy. After the incisions were closed either by suturing or by laser tissue welding (LTW), differences in the respective Raman spectra were identified. The study determined that the ratio of the Raman peaks of the amide III (1247 cm−1) band to a peak at 1326 cm−1 (the superposition of elastin and keratin bands) can be used to evaluate the progression of wound healing. Conformational changes in the amide I band (1633 cm−1 to 1682 cm−1) and spectrum changes in the range of 1450 cm−1 to 1520 cm−1 were observed in LTW and sutured skin. The stages of the healing process of the guinea pig skin following LTW and suturing were evaluated by Raman spectroscopy, using histopathology as the gold standard. LTW skin demonstrated better healing than sutured skin, exhibiting minimal hyperkeratosis, minimal collagen deposition, near-normal surface contour, and minimal loss of dermal appendages. A wavelet decomposition-reconstruction baseline correction algorithm was employed to remove the fluorescence wing from the Raman spectra. PMID:19581109

The incisions during orthognathic surgery are classically performed with conventional scalpel or electrocautery. Considering that the high-power diode laser surgery may provide advantages when compared to conventional incision techniques, the current study aimed to present a prospective case series of patients submitted to circumvestibular incision for Le Fort I osteotomy. Ten patients with dentofacial deformities who underwent to rapid assisted maxillary expansion or bimaxillary orthognathic surgery were enrolled in the study. All incisions were performed by a single surgeon using an 808-nm diode laser, with an optical fiber of 600 μm, at a power of 2.5 W, in a continuous-wave mode. The performance of the incision was evaluated by incision velocity, bleeding, edema, secondary infection, clinical healing, and pain. The velocity of the incision ranged from 0.10 to 0.20 mm/s (mean 0.13 ± 0.03 mm/s). Considering bleeding during the soft tissue incision, all surgeries were classified as absent bleeding. All patients presented a clinical healing of the surgical wound in a period that range from 3 to 5 weeks and experienced swelling during the follow-up period. On average, approximately 50% of the swelling had resolved after the third postoperative week, and 28.8% of swelling remained after 2 months after the surgery. The pain decreased after 2 and 3 days, and 90.0% of the patients reported no pain after 7 postoperative days. High-power diode laser is effective and safety during circumvestibular incisions for Le Fort I osteotomy in orthognathic surgery decreasing bleeding, surgery time, pain, and edema after orthognathic surgery.

2016-01-01

Background Conventional correction of malunioned zygoma requires complete regional exposure through a bicoronal flap combined with a lower eyelid incision and an upper buccal sulcus incision. However, there are many potential complications following bicoronal incisions, such as infection, hematoma, alopecia, scarring and nerve injury. We have adopted a zygomaticofrontal suture osteotomy technique using transconjunctival incision with lateral paracanthal extension. We performed a retrospective review of clinical cases underwent correction of malunioned zygoma with the approach to evaluate outcomes following this method. Methods Between June 2009 and September 2015, corrective osteotomies were performed in 14 patients with malunioned zygoma by a single surgeon. All 14 patients received both upper gingivobuccal and transconjunctival incisions with lateral paracanthal extension. The mean interval from injury to operation was 16 months (range, 12 months to 4 years), and the mean follow-up was 1 year (range, 4 months to 3 years). Results Our surgical approach technique allowed excellent access to the infraorbital rim, orbital floor, zygomaticofrontal suture and anterior surface of the maxilla. Of the 14 patients, only 1 patient suffered a complication—oral wound dehiscence. Among the 6 patients who received infraorbital nerve decompression, numbness was gradually relieved in 4 patients. Two patients continued to experience persistent numbness. Conclusion Transconjunctival incision with lateral paracanthal extension combined with upper gingivobuccal sulcus incision offers excellent exposure of the zygoma-orbit complex, and could be a valid alternative to the bicoronal approach for osteotomy of malunioned zygoma.

2007-03-01

We sought to determine the extent to which recent increases in levels of gender and racial diversity in the overall resident-physician workforce were evident among core-surgical specialty resident workforces. Chi-square tests for trend assessed the importance of changes from 1996 to 2004 in proportions of women and African Americans in the surgery-resident workforce. Surgery-resident trends were compared with overall resident workforce trends using two-tailed t-tests to compare regression slopes that quantified rates of change over time. Chi-square tests assessed differences between proportions of women and African Americans in the current overall board-certified workforce and their proportions in the surgery board-certified workforce. From 1996 to 2004, proportions of women increased in all seven surgical specialties studied. Compared with the overall trend toward increasing proportions of women in the resident workforce, the trend in one surgical specialty was larger (obstetrics/gynecology, p < 0.01), four were similar (each p > 0.05), and two were smaller (each p < 0.001). Proportions of African Americans increased in four specialties. Compared with the overall trend, trends in two specialties were larger (obstetrics/gynecology and neurologic surgery, each p < 0.01) and two were similar (each p > 0.05). Proportions of African Americans decreased in three specialties (each p < 0.01). Proportions of women and African Americans in every board-certified specialty workforce, except obstetrics/gynecology, remained lower than in the overall board-certified workforce (each p < 0.01). Many demographic disparities between the surgery-resident and overall-resident workforces have persisted since 1996 and will likely perpetuate ongoing surgery board-certified workforce disparities.

This study assessed performance of seven suture types in subyearling Chinook salmon Oncorhynchus tshawytscha implanted with acoustic microtransmitters. Nonabsorbable (Ethilon) and absorbable (Monocryl) monofilament and nonabsorbable (Nurolon, silk) and absorbable (Vicryl, Vicryl Plus, Vicryl Rapide) braided sutures were used to close incisions in Chinook salmon. Monocryl exhibited greater suture retention than all other suture types 7 d after surgery. Both monofilament suture types were retained better than all braided suture types at 14 d. Incision openness and tag retention did not differ among suture types. Wound inflammation was similar for Ethilon, Monocryl, and Nurolon at 7 d. Wound ulceration wasmore » lower for Ethilon, Monocryl, and Nurolon than for all other suture types at 14 d post-surgery. Fish held in 12°C water had more desirable post-surgery healing characteristics (i.e., higher suture and tag retention and lower incision openness, wound inflammation, and ulceration) at 7 and 14 d after surgery than those held in 17°C water. The effect of surgeon was a significant predictor for all response variables at 7 d. This result emphasizes the importance of including surgeon as a variable in telemetry study analyses when multiple surgeons are used. Monocryl performed better with regard to post-surgery healing characteristics in the study fish. The overall results support the conclusion that Monocryl is the best suture material to close incisions created during surgical implantation of acoustic microtransmitters in subyearling Chinook salmon.« less

Ultrasound-guided plantar fascia release technique: a retrospective study of 46 feet.

Ultrasound-guided plantar fascia release offers the surgeon clear visualization of anatomy at the surgical site. This technique uses small arthroscopic dissecting instruments through a 0.5-cm incision, allowing the surgeon to avoid the larger and more tissue-disruptive incision that is traditionally used for plantar heel spur resection and plantar fascia releases. Forty-one patients (46 feet) were selected for the study. The mean patient age was 47 years. Twenty-nine were considered obese with a body mass index greater than 30 kg/m(2). Patients were functionally and subjectively evaluated 4 weeks after surgery using the American Orthopedic Foot and Ankle Society Ankle and Hindfoot Rating Scale. Results from the study show a significant improvement (P = .05 confidence level) 4 weeks postoperatively for the 41 patients (46 feet), compared to their preoperative condition. The mean pretest score was 33.6 (range 10-52); this score improved to 88.0 (range 50-100), 4 weeks postoperatively. There were no postoperative infections or complications. The ultrasound-guided plantar fascia release technique is a practical surgical procedure for the relief of chronic plantar fascia pain because the surgeon is able to clearly visualize the plantar fascia by ultrasound. In addition, there is minimal disruption to surrounding tissue because small instruments are passed through a small 0.5-cm incision. The traditional open method of heel spur surgery, in contrast, uses a larger skin incision of 3 to 5 cm, followed by larger instruments to dissect to the plantar fascia.

The teaching of obstetrics and gynaecology in Singapore from 1905 to the present.

Medical education commenced a century ago in 1905. In 1922, the Department of Midwifery and Gynaecology was established. This was renamed the Department of Obstetrics in 1951. Medical undergraduate curriculum in Obstetrics and Gynaecology has evolved and undergone radical changes. From a compulsory 11-week residential posting in Kandang Kerbau Hospital, medical students are now only expected to be resident when they are scheduled for night duties. Having been an examination subject by itself in the Final MBBS Examination, Obstetrics and Gynaecology has in the latest revised undergraduate medical curriculum been incorporated into the Surgical tract and has ceased to be evaluated as a subject on its own. In this review, the establishment of postgraduate training in Obstetrics and Gynaecology is traced over the last 50 years and the important changes over the years are described. The first local Master of Medicine (Obstetrics and Gynaecology) was awarded in 1971. Currently, the specialist training for Obstetrics and Gynaecology in Singapore spans a period of 6 years, comprising 3 years of basic structural training and 3 years of advanced structural training. Over the years, the Department of Obstetrics and Gynaecology, National University of Singapore, has played a pivotal role in the teaching of clinical and laboratory research. This has added substantially to Singapore's efforts to become a world-class knowledge hub, especially in the areas of relevance to Obstetrics and Gynaecology.

Plantar Fascia Release Through a Single Lateral Incision in the Operative Management of a Cavovarus Foot: A Cadaver Model Analysis of the Operative Technique.

Plantar fascia release and calcaneal slide osteotomy are often components of the surgical management for cavovarus deformities of the foot. In this setting, plantar fascia release has traditionally been performed through an incision over the medial calcaneal tuberosity, and the calcaneal osteotomy through a lateral incision. Two separate incisions can potentially increase the operative time and morbidity. The purpose of the present study was threefold: to describe the operative technique, use cadaveric dissection to analyze whether a full release of the plantar fascia was possible through the lateral incision, and examine the proximity of the medial neurovascular structures to both the plantar fascia release and calcaneal slide osteotomy when performed together. In our cadaveric dissections, we found that full release of the plantar fascia is possible through the lateral incision with no obvious damage to the medial neurovascular structures. We also found that the calcaneal branch of the tibial nerve reliably crossed the osteotomy in all specimens. We have concluded that both the plantar fascia release and the calcaneal osteotomy can be safely performed through a lateral incision, if care is taken when completing the calcaneal osteotomy to ensure that the medial neurovascular structures remain uninjured.

In low-income and middle-income countries, surgical epidemiology is largely undefined at the population level, with operative logs and hospital records serving as a proxy. This study assesses the distribution of surgical conditions that contribute the largest burden of surgical disease in Burera District, in northern Rwanda. We hypothesise that our results would yield higher rates of surgical disease than current estimates (from 2006) for similar low-income countries, which are 295 per 100 000 people. In March and May, 2012, we performed a cross-sectional study in Burera District, randomly sampling 30 villages with probability proportionate to size and randomly sampling 23 households within the selected villages. Six Rwandan surgical postgraduates and physicians conducted physical examinations on all eligible participants in sampled households. Participants were assessed for injuries or wounds, hernias, hydroceles, breast mass, neck mass, obstetric fistula, undescended testes, hypospadias, hydrocephalus, cleft lip or palate, and club foot. Ethical approval was obtained from Boston Children's Hospital (Boston, MA, USA) and the Rwandan National Ethics Committee (Kigali, Rwanda). Informed consent was obtained from all participants. Of the 2165 examined individuals, the overall prevalence of any surgical condition was 12% (95% CI 9·2-14·9) or 12 009 per 100 000 people. Injuries or wounds accounted for 55% of the prevalence and hernias or hydroceles accounted for 40%, followed by neck mass (4·2%), undescended testes (1·9%), breast mass (1·2%), club foot (1%), hypospadias (0·6%), hydrocephalus (0·6%), cleft lip or palate (0%), and obstetric fistula (0%). When comparing study participant characteristics, no statistical difference in overall prevalence was noted when examining sex, wealth, education, and travel time to the nearest hospital. Total rates of surgically treatable disease yielded a statistically significant difference compared with current estimates (p<0·001). Rates of surgically treatable disease are significantly higher than previous estimates in comparable low-income countries. The prevalence of surgically treatable disease is evenly distributed across demographic parameters. From these results, we conclude that strengthening the Rwandan health system's surgical capacity, particularly in rural areas, could have meaningful affect on the entire population. Further community-based surgical epidemiological studies are needed in low-income and middle-income countries to provide the best data available for health system planning.

We analyze and discuss the clinical presentation, the diagnostic procedures and the surgical technique in relation to post-operative complications and results in cervico-mediastinal thyroid masses admitted in Thoracic Surgery Unit of AOU Second University of Naples from 1991 to 2006 and in Thoracic Surgery Unit of AOU "S. Giovanni di Dio & Ruggi D'Aragona" of Salerno over a period of 3 years (2011-2014). We reviewed 97 patients who underwent surgical treatment for cervico-mediastinal goiters. 47 patients (49.2%) had cervico-mediastinal goiter, 40 patients (40%) had mediastino-cervical goiter and 10 patients (10.8%) had mediastinal goiter. 73 cases were prevascular goiters and 24 were retrovascular goiters. We performed total thyroidectomy in 40 patients, subtotal thyroidectomy in 46 patients and in 11 cases the resection of residual goiter. In 75 patients we used only a cervical approach, in 21 patients the cervical incision was combined with median sternotomy and in 1 patient with transverse sternotomy. Three patients (3.1%) died in the postoperative period (2 cardio-respiratory failure and 1 pulmonary embolism). The histologic study revelead 8 (7.7%) carcinomas. Postoperative complications were: dyspnea in 9 cases (10.7%), transient vocal cord paralysis in 6 patients (9.2%), temporary hypoparathyroidism in 9 patients (9.2%) and kidney failure in 1 case (0.9%). The presence of a cervico-mediastinal thyroid mass with or without respiratory distress requires a surgical excision as the only treatment option. Thyroid masses extending to the mediastinum can be excised successfully by cervical incision. Bipolar approach (cervical incision and sternotomy) has an excellent outcome, achieving a safe resection, especially in large thyroid masses extending to the mediastinum with close relations to mediastinal structures and in some limited cases (carcinoma, thyroiditis, retrovascular goiter, ectopic goiter). Postoperative mortality and morbidity is very low, independent of surgical techniques. Other surgical approaches for excision of a Posterior Mediastinal Thyroid Goiter reported in literature are: VATS techniques to remove an ectopic intrathoracic goiter, robot-assisted technique for the removal of a substernal thyroid goiter, with extension into the posterior mediastinum.

Exposure to commonly performed gynecologic procedures via simulation has potential to improve medical student knowledge and foster confidence with procedures. To implement and evaluate a gynecologic simulation curriculum for 3rd-year medical students during their obstetrics and gynecology core clerkship. A gynecologic simulation curriculum was implemented for medical students during their obstetrics and gynecology clerkship. Participants completed pre-and postsurveys to assess learner confidence; effect on interest in a surgical field, women's health, and obstetrics and gynecology as a career; and whether the session met their learning needs. Fifty-nine students participated. Improved confidence in performing the procedures was noted when comparing mean survey scores before and after the simulation for IUD insertion and removal (1.9 pre, 4.3 post, p < .0001), for dilatation and curettage (1.7 pre, 3.8 post, p < .0001), and basic laparoscopy skills (2.1 pre, 4.3 post, p < .0001). An increase in pursuing a surgical field (3.3 pre, 3.6 post, p < .003) and interest in women's health (3.7 pre, 4.9 post, p < .004) was noted among students after the simulation session. The curriculum strongly met the students learning needs with a mean score of 4.54 on the 5-point scale. Gynecologic simulation training for medical students can increase confidence in procedures, interest in pursuing a surgical field and women's health, and was highly effective in meeting student learning needs.

Obstetric fistula is a worldwide problem that is devastating for women in developing countries. The cardinal cause of obstetric fistula is prolonged obstructed labour and delay in seeking emergency obstetric care. Awareness about obstetric fistula is still low in developing countries. The objective was to assess the awareness about risk factors of obstetric fistulae in rural communities of Nabitovu village, Iganga district, Eastern Uganda. A qualitative study using focus group discussion for males and females aged 18-49 years, to explore and gain deeper understanding of their awareness of existence, causes, clinical presentation and preventive measures for obstetric fistula. Data was analyzed by thematic analysis. The majority of the women and a few men were aware about obstetric fistula, though many had misconceptions regarding its causes, clinical presentation and prevention. Some wrongly attributed fistula to misuse of family planning, having sex during the menstruation period, curses by relatives, sexually transmitted infections, rape and gender-based violence. However, others attributed the fistula to delays to access medical care, induced abortions, conception at an early age, utilization of traditional birth attendants at delivery, and some complications that could occur during surgical operations for difficult deliveries. Most of the community members interviewed were aware of the risk factors of obstetric fistula. Some respondents, predominantly men, had misconceptions/myths about risk factors of obstetric fistula as being caused by having sex during menstrual periods, poor usage of family planning, being a curse.

Abstract Background: Laparoscopic and robot-assisted surgeries are performed under carbon dioxide insufflation. Switching from gas to an isotonic irrigant introduces several benefits and avoids some adverse effects of gas insufflation. We developed an irrigating device and apparatus designed for single-incision laparoscopic surgery and tested its advantages and drawbacks during surgery in a porcine model. Materials and Methods: Six pigs underwent surgical procedures under general anesthesia. A 30-cm extracorporeal cistern was placed over a 5–6-cm abdominal incision. The abdomen was irrigated with warm saline that was drained via a suction tube placed near the surgical field and continuously recirculated through a closed circuit equipped with a hemodialyzer as a filter. Irrigant samples from two pigs were cultured to check for bacterial and fungal contamination. Body weight was measured before and after surgery in four pigs that had not received treatments affecting hemodynamics or causing diuresis. Results: One-way flow of irrigant ensured laparoscopic vision by rinsing blood from the surgical field. Through a retroperitoneal approach, cystoprostatectomy was successfully performed in three pigs, nephrectomy in two, renal excision in two, and partial nephrectomy in one, under simultaneous ultrasonographic monitoring. Through a transperitoneal approach, liver excision and hemostasis with a bipolar sealing device were performed in three pigs, and bladder pedicle excision was performed in one pig. Bacterial and fungal contamination of the irrigant was observed on the draining side of the circuit, but the filter captured the contaminants. Body weight increased by a median of 2.1% (range, 1.2–4.4%) of initial weight after 3–5 hours of irrigation. Conclusions: Surgery under irrigation is feasible and practical when performed via a cistern through a small abdominal incision. This method is advantageous, especially in the enabling of continuous and free-angle ultrasound observation of parenchymal organs. Adverse effects of abdominal irrigation need further assessment before use in humans. PMID:26745012

New therapeutics to manage post-surgical pain are needed to mitigate the liabilities of opioid and other analgesics. Our previous work shows that key modulators of excitability in peripheral nociceptors, such as extracellular signal-regulated kinases (ERK) are inhibited by activation of adenosine monophosphate activated protein kinase (AMPK). We hypothesized that AMPK activation would attenuate acute incision-evoked mechanical hypersensitivity and the development of hyperalgesic priming caused by surgery in mice. Here we have used a variety of administration routes and combinations of AMPK activators to test this hypothesis. Topical administration of a resveratrol-based cream inhibited acute mechanical hypersensitivity evoked by incision and blocked the development of hyperalgesic priming. We also observed that systemic administration of metformin dose-dependently inhibited incision-evoked mechanical hypersensitivity and hyperalgesic priming. Interestingly, low doses of systemic metformin and local resveratrol that had no acute effect were able to mitigate development of hyperalgesic priming. Combined treatment with doses of systemic metformin and local resveratrol that were not effective on their own enhanced the acute efficacy of the individual AMPK activators for post-surgical mechanical pain alleviation and blocked the development of hyperalgesic priming. Finally, we used dorsal root ganglion (DRG) neurons in culture to show that resveratrol and metformin given in combination shift the concentration-response curve for AMPK activation to the left and increase the magnitude of AMPK activation. Therefore, we find that topical administration is an effective treatment route of administration and combining systemic and local treatments led to anti-nociceptive efficacy in acute mechanical hypersensitivity at doses that were not effective alone. Collectively our work demonstrates a specific effect of AMPK activators on post-surgical pain and points to novel therapeutic opportunities with potential immediate impact in the clinical setting.

Combined approach branchial sinusectomy: a new technique for excision of second branchial cleft sinus.

PubMed

Olusesi, A D

2009-10-01

Branchial cleft anomalies are well described, with the second arch anomaly being the commonest. Following surgical excision, recurrence occurs in 2 to 22 per cent of cases, and is believed to be due largely to incomplete resection. This report aims to describe a simple surgical technique for treatment of second branchial cleft sinus in the older paediatric age group and adults. An 11-year-old girl underwent surgical excision of a second branchial sinus. Prior to surgery, she was assessed by means of an imaging sonogram, and by direct methylene blue dye injection into the sinus on the operating table, followed by insertion of a metallic probe. Dissection was of the 'step ladder' incision type, but the incision was completed via an oropharyngeal approach. Histological examination of the lesion after excision established the diagnosis. No recurrence had been observed at the time of writing. Although they are congenital lesions, second branchial cleft abnormalities usually present in the older paediatric age group or even in adulthood. In the case reported, a simple combined approach ensured completeness of resection.

Background: Gynecomastia is a deformity of male chest. Treatment of gynecomastia varied from direct surgical excision to other techniques (mainly liposuction) to a combination of both. Skin excision is done according to the grade. In this study, experience of using liposuction adjuvant to surgical excision was described. Patients and methods: Between September 2012 and April 2015, a total of 14 patients were treated with liposuction and surgical excision through a periareolar incision. Preoperative evaluation was done in all cases to exclude any underlying cause of gynecomastia. Results: All fourteen patients were treated bilaterally (28 breast tissues). Their ages ranged between 13 and 33 years. Two patients were classified as grade I, and four as grade IIa, IIb or III, respectively. The first 3 patients showed seroma. Partial superficial epidermolysis of areola occurred in 2 cases. Superficial infection of incision occurred in one case and was treated conservatively. Conclusion: All grades of gynecomastia were managed by the same approach. Skin excision was added to a patient that had severe skin excess with limited activity and bad skin complexion. No cases required another setting or asked for 2nd opinion. PMID:26955509

Evidence-based guidelines for the prevention of surgical site infection (SSI) have been published by the U.S. Centers for Disease Control and Prevention (CDC). According to these guidelines, a wound should usually be covered with a sterile dressing for 24 to 48 h when a surgical incision is closed primarily. However, it is not recommended that an incision be covered by a dressing beyond 48 h. In this study, patients were stratified into two groups for analysis: patients whose surgical wound was sterilized and whose gauze was changed once daily until postoperative day 7 (7POD; group A); and patients whose surgical wound was sterilized and whose gauze was changed once daily until 2POD (group B). We evaluated the incidence of SSI, nursing hours and cost implications. The results showed that there was no significant difference in SSI occurrence between the two groups (group A, 10% vs. group B, 7.3%). By contrast, the average nursing time differed by 2.8 min (group A, 3.8 min vs. group B, 0.9 min). The material costs per patient were also reduced by $14.70 (group A, $61.80 vs. group B, $47.10). In conclusion, we applied our knowledge of the evidence-based CDC guidelines to determine whether 48-h wound management can be made easier, more uniform and more cost-effective compared to conventional wound management. The results of the present study showed that surgical wound management methods can be more convenient and inexpensive.

Minimally Invasive Surgical Pulmonary Embolectomy: A Potential Alternative to Conventional Sternotomy.

Surgical pulmonary embolectomy has gained increasing popularity over the past decade with multiple series reporting excellent outcomes in the treatment of submassive pulmonary embolism. However, a significant barrier to the broader adoption of surgical pulmonary embolectomy remains the large incision and long recovery after a full sternotomy. We report the safety and efficacy of using a minimally invasive approach to surgical pulmonary embolectomy. All consecutive patients undergoing surgical pulmonary embolectomy for a submassive pulmonary embolism (2015-2017) were reviewed. Patients were stratified as conventional or minimally invasive. The minimally invasive approach included a 5- to 7-cm skin incision with upper hemisternotomy to the third intercostal space. The primary outcomes were in-hospital and 90-day survival. Thirty patients (conventional = 20, minimally invasive = 10) were identified. Operative time was similar between the two groups, but cardiopulmonary bypass time was significantly longer in the minimally invasive group (58 vs 94 minutes, P = 0.04). While ventilator time and intensive care unit length of stay were similar between groups, hospital length of stay was 4.5 days shorter in the minimally invasive group, and there was a trend toward less blood product use. In-hospital and 90-day survival was 100%. Within the minimally invasive cohort, median right ventricular dysfunction at discharge was none-mild and no patient experienced postoperative renal failure, deep sternal wound infection, sepsis, or stroke. Minimally invasive surgical pulmonary embolectomy appears to be a feasible approach in the treatment of patients with a submassive pulmonary embolism. A larger, prospective analysis comparing this modality with conventional surgical pulmonary embolectomy may be warranted.

Strategies of preventing ureteral iatrogenic injuries in obstetrics-gynecology

The incidence of ureteral lesions varies between 0.1% and 30% depending on the type of the surgical intervention. However, the surgical interventions in Obstetrics and Gynecology are responsible for 50% of the total iatrogenic ureteral lesions. Sadly, only 1/3 of the iatrogenic ureteral lesions are recognized during surgeries and 25% of the unrecognized cases of ureteral lesions lead towards the loss of the damaged kidney, while a delayed diagnostic may also lead to a progressive deterioration of the renal function. On this matter, of decreasing the rate of morbidity and the following forensic risks, the gynecologist surgeon must be able to anticipate the potential apparition of a specific ureteral lesion, based on the known risk factors of the patient, so that he can then prevent the iatrogenic ureteral lesion.

Cemento-ossifying Fibroma (COF) is an osteogenic benign neoplasm affecting the jaws and other craniofacial bones. It commonly presents as a progressively slow growing pathology, which can sometimes attain an enormous size, causing facial deformity. A case of a huge cemento-ossifying fibroma, appearing as a mandibular dumbell tumour in a male patient is documented, which caused massive bone destruction and deformity. It was surgically removed by performing en bloc resection of mandible avoiding the splitting of lower lip incision technique, thereby maintaining his normal facial appearance.

Challenges intrinsic to the accurate diagnosis of endometriosis contribute to an extended delay between the onset of symptoms and clinical confirmation. Intraoperative visualization, preferably with histologic verification, is considered by many professional organizations to be the gold standard by which endometriosis is diagnosed. Clinical diagnosis of symptomatic endometriosis via patient history, physical examination, and noninvasive tests, though more easily executed, is generally viewed as less accurate than surgical diagnosis. Technological advances and increased understanding of the pathophysiology of endometriosis warrant continuing reevaluation of the standard method for diagnosing symptomatic disease. A review of the published literature was therefore performed with the goal of comparing the accuracy of clinical diagnostic measures with that of surgical diagnosis. The current body of evidence suggests that clinical diagnosis of symptomatic endometriosis is more reliable than previously recognized and that surgical diagnosis has limitations that could be underappreciated. Regardless of the methodology used, women with suspected symptomatic endometriosis would be well served by a diagnostic paradigm that is reliable, conveys minimal risk of under- or over-diagnosis, lessens the time from symptom development to diagnosis, and guides the appropriate use of medical and surgical management strategies. © 2018 The Authors.

Obstetric hemorrhage remains a major cause of maternal morbidity and mortality worldwide. Traditionally, in cases of obstetric hemorrhage refractory to conservative treatment, obstetricians have resorted to major surgery with the associated risks of general anesthesia, laparotomy, and, in the case of hysterectomy, loss of fertility. Over the past two decades, the role of pelvic arterial embolization has evolved from a novel treatment option to playing a key role in the management of obstetric hemorrhage. To date, interventional radiology offers a minimally invasive, fertility-preserving alternative to conventional surgical treatment. We review current literature regarding the role of interventional radiology in postpartummore » hemorrhage, abnormal placentation, abortion, and cervical ectopic pregnancy.

The aim of the study was to compare the clinical outcomes of a 1.8 mm, 2.2 mm, and 2.75 mm microcoaxial cataract surgery system. METHODS. In this retrospective study, 129 eyes of 129 patients were included. Patients underwent phacoemulsification using a Stellaris system or an Infiniti system. The incision size was 1.8 mm, 2.2 mm, or 2.75 mm, respectively. Subjects were examined before surgery and 4 weeks after. The surgically induced astigmatism (SIA) was examined. The SIA in the 1.8 mm group was statistically lower compared to the 2.2 mm group (p=0.046) and the 2.75 mm group (p=0.017). There was no significant difference between the 2.2 mm group and the 2.75 mm group. With the use of appropriate support systems, 1.8 mm incisions appear to result in less SIA than 2.2 mm and 2.75 mm incisions. Advantages may arise from this, especially in the implantation of aspheric, toric, or multifocal lenses.

To evaluate surgically induced astigmatism as computed by means of either simulated keratometry (K SIM ) or total corneal refractive power (TCRP) after temporal incisions. Prospective observational study including 36 right eyes undergoing cataract surgery. Astigmatism was measured preoperatively during the 3-month follow-up period using Pentacam. Surgically induced astigmatism was computed considering anterior corneal surface astigmatism at 3 mm with K SIM and considering both corneal surfaces with TCRP from 1 to 8 mm (TCRP 3 for 3 mm). The eyes under study were divided into two balanced groups: LOW with K SIM astigmatism <0.90 D and HIGH with K SIM astigmatism ≥0.90 D. Resulting surgically induced astigmatism values were compared across groups and measuring techniques by means of flattening, steepening, and torque analysis. Mean surgically induced astigmatism was higher in the HIGH group (0.31 D @ 102°) than in the LOW group (0.04 D @ 16°). The temporal incision resulted in a steepening in the HIGH group of 0.15 D @ 90°, as estimated with K SIM , versus 0.28 D @ 90° with TCRP 3 , but no significant differences were found for the steepening in the LOW group or for the torque in either group. Differences between K SIM - and TCRP 3 -based surgically induced astigmatism values were negligible in LOW group. Surgically induced astigmatism was considerably higher in the high-astigmatism group and its value was underestimated with the K SIM approach. Eyes having low astigmatism should not be included for computing the surgically induced astigmatism because steepening would be underestimated.

The purpose of this study was to investigate the use of antibiotic prophylaxis for plastic surgical procedures at our hospital, and to perform a systematic literature review of randomized controlled trials evaluating the use of prophylactic antibiotics in plastic surgery. The records of patients who received plastic surgical procedures with Class I surgical incisions between 2009 and 2010 were retrospectively reviewed. A systematic literature review was conducted for studies examining the use of prophylactic antibiotics for Class I surgical wounds. A total of 13,997 cases with Class I surgical incisions were included. Prophylactic antibiotics were given in 13,865 cases (99.1%). The antibiotics used were primarily cefuroxime, clindamycin, metronidazole, cefoxitin sodium, and gentamicin. The average duration of administration was 4.84 ± 3.07 (range, 1-51) days. Antibiotics were administered postoperatively in >99% of cases while preoperative antibiotic administration was only given in 32 cases (0.23%). Wound infections occurred in 21 cases for an overall infection rate of 0.15%. Fourteen studies met the inclusion criteria of the systematic review. There was marked variation in the timing of antibiotic administration with antibiotics given pre-, peri-, and postoperatively. Of studies that compared the use of prophylactic antibiotics with placebo, a reduction in wound infections was noted in 4 trials and no difference was noted in 6 trials. No significant difference in infection rates was shown between the prophylactic and postoperative arms. In conclusion, prophylactic antibiotics are overused in plastic surgical procedures. Evidence-based guidelines for the use of prophylactic antibiotics in plastic surgical procedures are needed. Copyright © 2014 Surgical Associates Ltd. Published by Elsevier Ltd. All rights reserved.

Loop colostomy prolapse is associated with an impaired quality of life. Surgical treatment may sometimes be required for cases that cannot be closed by colon colostomy because of high-risk morbidities or advanced disease. We applied the Altimeter operation for patients with transverse loop colostomy. The Altemeier operation is therefore indicated for rectal prolapse. This technique involves a simple operation, which includes a circumferential incision through the full thickness of the outer and inner cylinder of the prolapsed limb, without incising the abdominal wall, and anastomosis with sutures using absorbable thread. We performed the Altemeier operation for three cases of loop stomal prolapse. Those patients demonstrated no postoperative complications (including obstruction, prolapse recurrence, or hernia). Our findings suggest that this procedure is useful as an optional surgical treatment for cases of transverse loop colostomy prolapse as a permanent measure in patients with high-risk morbidities or advanced disease.

The position of the skin paddle on the breast area is a fundamental element for the breast reconstructions by latissimus dorsi flap and prosthesis implantation. Should, as Millard advocated, to recreate the initial defect and include it in the mastectomy scar or is it better in an additional incision as have others authors. This study compares the long-term morphological results of these two attitudes, with or without additional incision. Eighty-two breast reconstructions by latissimus dorsi flap and prosthesis implantation, with a mean follow-up of 9.5 years were scored from 1 to 5 by a panel of expert and non-expert. The patients scored also their own reconstruction. Various parameters of the reconstructed breast were thus evaluated. We compared the results, according to the positioning of the skin paddle: with additional incision (50 cases); without additional incision (32 cases). The characteristics of the mastectomy scar on the breast area, high or low, horizontal or oblique, defined 6 groups where the results of the 2 surgical options were compared. Only the reconstructions with additional incision get significantly higher results than those without additional incision (P<0.05). This involves the two panels, in the case of high mastectomy scars. In the others cases the additional incision is not essential. If the realization of an additional incision can be perceived like misfit on an area already "mutilated", we plead for this solution in selected cases. This provides a benefit stable in time, in terms of overall results, shape and even rendering scar. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Trans-subxiphoid robotic thymectomy.

Suda, Takashi; Tochii, Daisuke; Tochii, Sachiko; Takagi, Yasushi

2015-05-01

Minimally invasive surgery has replaced median sternotomy for resectable anterior mediastinal masses and is performed by various approaches. We developed a new minimally invasive surgical procedure by combining the subxiphoid approach performed through a midline camera port with the use of a robotic surgery system (Intuitive Surgical, Sunnyvale, CA, USA). A 3-cm transverse incision was made 1 cm below the xiphoid process. Then, a port designed for single-port surgery was inserted. Through this port, CO2 gas was injected at 8 mmHg. The thymus was then detached from the back of the sternum. A 1-cm skin incision was made bilaterally in the sixth intercostal space, followed by insertion of a port for the robotic system. A camera port was inserted into the subxiphoid port, to which the camera scope was mounted, and thymectomy was performed. We have performed the operation in 3 patients. In our experience, this procedure provides a good operative view in the neck region and makes verification of the phrenic nerve easy. Furthermore, with the da Vinci surgical system, which enables surgical manipulation from a correct angle due to the multijoint robotic arms, trans-subxiphoid robotic thymectomy may be a promising new thymectomy procedure. © The Author 2015.

Does pilonidal abscess heal quicker with off-midline incision and drainage?

PubMed

Webb, P M; Wysocki, A P

2011-06-01

No clinical trials have been done to guide the surgeon in the optimal technique of draining a pilonidal abscess. The aim of our study was to investigate whether the location of the incision influences wound healing. Electronic records from the surgical database at our 200-bed district general hospital were reviewed for operative technique (midline vs. lateral) for patients who underwent incision and drainage for acute pilonidal abscess between January 2003 and February 2010. These patients were admitted from the Emergency Department with a pilonidal abscess, underwent operative drainage, and returned for follow-up. The main outcome measure was wound healing time. Two hundred and forty-three pilonidal abscesses were drained, 134 with a lateral and 74 with a midline incision. All patients underwent simple longitudinal incision. No patient underwent de-roofing, marsupialisation, or closure. Forty-eight patients with midline drainage who returned for follow-up were matched for gender, age, and microbiology culture results with patients who underwent lateral drainage. Almost all were drained under general anesthesia with a median postoperative stay of 1 day. The overall length of follow-up was the same in both groups (P = 0.13). Abscesses that did not heal were followed-up for the same period of time irrespective of incision type (P = 0.48). Abscesses that healed after midline incision took approximately 3 weeks longer than those drained via a lateral incision (P = 0.02). Our study has limitations since it was a retrospective study that did not capture patients whose abscess drained spontaneously or were drained in the emergency department. Pilonidal abscess should be drained away from the midline.

To compare incision integrity and clinical outcomes of 2 microcoaxial phacoemulsification systems. Iladevi Cataract & IOL Research Centre, Ahmedabad, India. Prospective randomized clinical trial. Eyes were randomized to have phacoemulsification using a 1.8 mm clear corneal incision (CCI) system (Group 1, Stellaris system) or a 2.2 mm CCI system (Group 2, Intrepid Infiniti system). Incision enlargement at end of surgery was measured. At the conclusion of surgery, trypan blue was applied over the conjunctival surface, anterior chamber aspirate withdrawn, and ingress into anterior chamber measured. Postoperative observations included evaluation of the CCI using anterior segment optical coherence tomography (AS-OCT), change in central corneal thickness (CCT), and anterior segment inflammation at 1 day, 1 week, and 1 month and endothelial cell loss and surgically induced astigmatism (SIA) at 3 months. Incision enlargement (P<.001) and trypan blue ingress in the anterior chamber (mean 1.7 log units ± 0.6 [SD] versus 3.8 ± 0.6 log units, P<.001) was significantly greater in Group 1 (n = 50) than in Group 2 (n = 50). On AS-OCT, endothelial misalignment and gaping were more frequent in Group 1 at 1 day (P=.001) and 1 week (P=.018). There were no significant differences in SIA, change in CCT, endothelial cell loss, or anterior segment inflammation (P>.05). At the end of surgery, it is not the initial incision size alone but also the distortion of the incision during subsequent stages of surgery that determine the integrity of the CCI.

2004-12-01

We sought to assess the rabbit as an experimental animal in the investigation of laser skin soldering. We studied, using the scanning electron microscope (SEM), the surface appearances of experimental incisions made on the rabbit back skin and soldered by CO(2) laser. Laser soldering of incisions in various tissues is a modality of wound healing of a very promising clinical value. At present, more component studies on animals directed at paving the way towards clinical protocols are needed. Surgical incisions on rabbits back skin were bonded using either albumin-assisted CO(2) laser soldering (experimental) or thread suturing (reference). The incisions closed were excised 2, 3, 4, and 5 days postoperatively, and skin surfaces were studied in the SEM. Naked eye inspection and SEM analysis showed that full-length sealing of soldered and sutured incisions was discernible as early as day 2. In the SEM, all incisions were found confluently coated by epidermal cells along the former cut streak. Soldering subserved to bond incisions efficiently, with surface smooth and close to normal skin. On the other hand, the surface of sutured incisions appeared convoluted and its aesthetic quality inferior to that of the former. Some of the days two and three soldered incisions suffered dehiscence on excision, which suggests an incomplete regeneration of tensile strength at this early phase of healing. Sutured incisions tolerated excision, very probably due to the microthread still present in the skin tissue rather than because of breaking strength regained during wound healing. Also, hair stumps re-grown on the skin by day 5 postoperative might impair satisfactory microscopy of bonded incisions. CO(2) laser soldering of incisions on the rabbit back skin effected rapid wound sealing and resulted in smooth scars indistinguishable from normal skin. The rabbit is well suited for this kind of studies, provided that excision of experimental cuts takes place not later than 5 days post-incision so that hair stumps may not grow large enough to jeopardize the quality of scanning electron microscopy.

Knowledge of baseline laparoscopic and robotic surgical skills of future learners is essential to develop teaching strategies that best fit them. The objectives of this study are to determine baseline laparoscopic and robotic skills of high school and college students and compare them to those of current obstetrics and gynecology residents. A cross-sectional (Class II-2) pilot study. Laparoscopic and robotic surgical skills of college and high (secondary) school students were evaluated using simulators and compared to those of obstetrics and gynecology residents. In addition, questionnaire data were collected regarding video game playing and computer use. A total of 17 students, both high school (n=9) and college (n=8), in addition to 11 residents, completed the study. Overall, students performed comparably to the residents in simple exercises (p>.05). However, students took significantly longer time to complete complex exercises (p=.001). Finally, students played video games significantly more than residents (p<.001). Future learners may have a different background skill set. This difference may be related to improved hand-eye coordination, possibly due to playing video games. The results of this pilot study should spur more research into surgical teaching strategies.

Physics-based interactive volume manipulation for sharing surgical process.

Nakao, Megumi; Minato, Kotaro

2010-05-01

This paper presents a new set of techniques by which surgeons can interactively manipulate patient-specific volumetric models for sharing surgical process. To handle physical interaction between the surgical tools and organs, we propose a simple surface-constraint-based manipulation algorithm to consistently simulate common surgical manipulations such as grasping, holding and retraction. Our computation model is capable of simulating soft-tissue deformation and incision in real time. We also present visualization techniques in order to rapidly visualize time-varying, volumetric information on the deformed image. This paper demonstrates the success of the proposed methods in enabling the simulation of surgical processes, and the ways in which this simulation facilitates preoperative planning and rehearsal.

To describe the role of task delegation in the practice of major obstetric procedures in the Bogodogo health district hospital. This descriptive and analytic prospective study took place in the hospital's department of obstetrics and gynecology from February through October 2013. It included all women undergoing a major obstetric surgical intervention, performed by either by a gynecologist-obstetrician or by a nurse specializing in surgery. Data were collected from individual records and analyzed by SPSS and Epidata software. There were 601 major obstetric interventions during the study period. The women's mean age was 26.7 years. Cesarean deliveries accounted for 90% of these procedures, followed by laparotomy (7.7%). The Misgav-Ladach technique was used for cesareans by 86.5% of the obstetricians and 95.3% of the nurses specialized in surgery. The primary complications were anemia and postpartum hemorrhage. Maternal mortality did not differ significantly between the groups of operators, nor did maternal, fetal, and neonatal outcomes. Task delegation in obstetric surgery at the Bogodogo district hospital is effective. Its extension to the national level would make it possible to overcome the lack of highly qualified human resources to enable adequate availability of major obstetric interventions in rural hospitals.

INTRODUCTION More aesthetically acceptable treatment options have been sought to minimise the morbidity associated with open surgery for gynaecomastia. This study investigated the use of a vacuum-assisted biopsy device (VABD) and liposuction to provide minimally invasive approach. PATIENTS AND METHODS Patients diagnosed with idiopathic benign gynaecomastia referred to the Breast Care Unit of Castle Hill Hospital between June 2002 and April 2007 and requesting surgical intervention underwent VABD excision and liposuction. All patients underwent thorough investigations to exclude any underlying cause for their gynaecomastia. The procedure was carried out by a single consultant surgeon with special interest in breast surgery. An 8-G mammotome probe was advanced through a 4-mm incision positioned in the corresponding anterior axillary line to excise the glandular disc. Liposuction was performed through the same incision. Incision wounds were closed with Steristrips. A pressure dressing was applied over wound by corset and an inflatable device. RESULTS Thirty-six male patients with grade I and II gynaecomastia were recruited (22 bilateral, 14 unilateral). Average age was 33.3 years (range, 16–88 years). All underwent mammotome excision and liposuction. There were no conversions to an open procedure. The average procedure time was 50.3 min (range, 30–80 min). One intra-operative complication was recorded. The minimum follow-up time was 2 months. Thirty-four patients reported excellent satisfaction, two patients had residual gynaecomastia and needed a re-do procedure. Three patients developed small haematomas that resolved spontaneously. CONCLUSION This novel, minimally invasive, surgical approach for gynaecomastia gives excellent results with minimal morbidity. PMID:20412670

Introduction When surgeons operate on the foot and ankle, the most common complication that may arise is injury of the cutaneous nerves. The sural nerve (SN) is potentially at risk of being injured when treating fractures involving the distal tibia using the posterolateral approach. The aim of this study was to evaluate how differences in length and position of the surgical treatment of fractures involving the distal tibia can affect the risk of SN injury. Materials and Methods The study involved 40 healthy volunteers (n=80 lower limbs). Ultrasound simulation of each potential surgical incision site was used to locate the SN and to assess the risk of injury. Results The study showed that the SN predominantly travels more posteriorly at levels more proximal from the tip of the lateral malleolus. At these more proximal points of the SN's course, it was proven that there was an overall increased incidence of iatrogenic injury to the SN in incisions made closer to the Achilles tendon. Based on these results, a quasi 3 dimensional figure was created showing the anatomical structures of this region to identify areas at high risk for SN injury. Conclusions By revealing how length and position of the surgical incision can influence the risk of SN injury, we hope to provide information to surgeons on the optimal technique to avoid iatrogenic SN injury while operating on the distal tibia via a posterolateral approach.

To develop a realistic model of the optomechanical behavior of the cornea after curved relaxing incisions to simulate the induced astigmatic change and predict the optical aberrations produced by the incisions. ICMA Consejo Superior de Investigaciones Científicas and Universidad de Zaragoza, Zaragoza, Spain. A 3-dimensional finite element model of the anterior hemisphere of the ocular surface was used. The corneal tissue was modeled as a quasi-incompressible, anisotropic hyperelastic constitutive behavior strongly dependent on the physiological collagen fibril distribution. Similar behaviors were assigned to the limbus and sclera. With this model, some corneal incisions were computer simulated after the Lindstrom nomogram. The resulting geometry of the biomechanical simulation was analyzed in the optical zone, and finite ray tracing was performed to compute refractive power and higher-order aberrations (HOAs). The finite-element simulation provided new geometry of the corneal surfaces, from which elevation topographies were obtained. The surgically induced astigmatism (SIA) of the simulated incisions according to the Lindstrom nomogram was computed by finite ray tracing. However, paraxial computations would yield slightly different results (undercorrection of astigmatism). In addition, arcuate incisions would induce significant amounts of HOAs. Finite-element models, together with finite ray-tracing computations, yielded realistic simulations of the biomechanical and optical changes induced by relaxing incisions. The model reproduced the SIA indicated by the Lindstrom nomogram for the simulated incisions and predicted a significant increase in optical aberrations induced by arcuate keratotomy.

Hereditary spherocytosis is an autosomal dominant inheritance disorder of the red blood cell membrane characterized by the presence of spherical-shaped erythrocytes (spherocytes) in the peripheral blood. The main clinical features include haemolytic anemia, variable jaundice, splenomegaly and cholelithiasis caused by hyperbilirubinemia from erythrocyte hemolysis. Splenectomy does not solve the congenital genetic defect but it stops pathological hemolysis in the enlarged spleen. If gallstones are present, it is appropriate to perform cholecystectomy at the time of splenectomy, although the patient has symptoms of gall bladder disease. We present the case of single incision laparoscopic surgical (SILS) concomitant splenectomy and cholecystectomy performed with conventional laparoscopic instruments in an 11-year-old girl with the diagnosis of hereditary spherocytosis. A 2-3 cm umbilical incision was used for the placement of two 5 mm trocars and one 10 mm flexible videoscope. Conventional laparoscopic dissector, grasper, Ligasure, Harmonic Ace and hemoclips were the main tools during surgical procedure. We prefer Single Incision Laparoscopic Surgery Foam Port (Covidien) as the single umbilical device for introduction into the abdominal cavity. First, we performed cholecystectomy, then the gallbladder was put aside over the liver and after that we peformed splenectomy. To remove the detached spleen and gallbladder, a nylon extraction bag is introduced through one of the port sites. The spleen is than morcellated in the bag with forceps and removed in fragments. After that we removed them and the umbilical fascial incision was closed. Splenectomy is the only effective therapy for this disorder and often it is performed in combination with cholecystectomy. Conventional surgery requires a wide upper abdominal incision for correct exposure of the gallbladder and spleen. Our experience shows that SILS splenectomy and cholecystectomy is feasible even in young children and despite the small number of cases in the world, we consider the combined laparoscopic approach safe and effective for the treatment of hereditary spherocytosis. According to actually published guidelines, the laparoscopic approach to concomitant splenectomy and cholecystectomy is recommended, but it depends on the availability of appropriately trained surgeons and suitable equipment.

OBJECTIVE To describe the technique, clinical findings, and short-term outcome in dogs undergoing laparoscopic-assisted incisional gastropexy with a reusable single-incision surgery port. DESIGN Retrospective case series. ANIMALS 14 client-owned dogs. PROCEDURES Medical records of dogs referred for elective laparoscopic gastropexy between June 2012 and August 2013 were reviewed. History, signalment, results of physical examination and preoperative laboratory testing, surgical procedure, duration of surgery, postoperative complications, duration of hospital stay, and short-term outcome were recorded. All patients underwent general anesthesia and were positioned in dorsal recumbency. After an initial limited laparoscopic exploration, single-incision laparoscopic-assisted gastropexy was performed extracorporeally in all dogs via a conical port placed in a right paramedian location. Concurrent procedures included laparoscopic ovariectomy (n = 4), gastric biopsy (2), and castration (7). Short-term outcome was evaluated. RESULTS Median duration of surgery was 76 minutes (range, 40 to 90 minutes). Intraoperative complications were minor and consisted of loss of pneumoperitoneum in 2 of 14 dogs. A postoperative surgical site infection occurred in 1 dog and resolved with standard treatment. Median duration of follow-up was 371 days (range, 2 weeks to 1.5 years). No dogs developed gastric dilation-volvulus during the follow-up period, and all owners were satisfied with the outcome. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that single-incision laparoscopic-assisted gastropexy with a reusable conical port was feasible and effective in appropriately selected cases. Investigation of the potential benefits of this reusable port versus single-use devices for elective gastropexy in dogs is warranted.

To report the clinical features and outcomes of linear gastrointestinal incisions closed with skin staples in dogs. Historical cohort study. 333 client-owned dogs. Medical records from 1 private referral hospital were searched for dogs that underwent gastrointestinal surgery between November 1999 and October 2015. Cases were included if skin staplers were used to close linear gastrointestinal incisions. Information regarding preoperative, surgical, and postoperative factors was collected. Complications were diagnosed in 8 of 245 (3.27%) dogs, including 3 of 245 (1.22%) dogs that died or were euthanized, 3 of 245 (1.22%) dogs with incisional dehiscence, and 2 of 245 (0.81%) dogs with attachment of a linear foreign body to the staples at the intestinal lumen. Dehiscence was noted at the enterotomy sites in 3 dogs at a mean time of 44 hours after surgery (SD ± 6.93). Two dogs presented with another linear foreign body that was attached to the staples in the intestinal lumen at postoperative days 24 and 42. The risk factors associated with incisional dehiscence included multiple gastrointestinal incisions performed in 1 surgery (χ 2 , P < .001) and the presence of a linear foreign body (χ 2 , P = .02253). No associations were detected between dogs' age, sex, weight, surgery time, indication for surgical intervention, surgery location in the gastrointestinal tract, or surgeon experience and incisional dehiscence. Skin staplers provide safe and effective closure of gastrotomies, enterotomies, and colonotomies in dogs. This method is reliable, efficient, and affordable in the hands of veterinary surgeons with varying skill levels. © 2017 The American College of Veterinary Surgeons.

This study aimed to evaluate the effects of ultrasound-guided rectus sheath block in gynaecological surgery with Pfannenstiel incision. After the approval of the ethics committee and the patients' consent, 75 ASA I-II patients who were aged between 20 and 70 years and scheduled for a gynaecological surgery with Pfannenstiel incision were included in this study. After induction of general anaesthesia, patients were randomly divided into three groups. In Group UR patients (n=25), ultrasound-guided rectus sheath block with 0.25% levobupivacaine (0.2 mL kg(-1)) was performed. In Group SR patients (n=25), surgical rectus sheath block with 0.25% levobupivacaine (0.2 mL kg(-1)) was applied. In Group T (n=25) patients, tramadol (2 mg kg(-1)) was intravenously administered 30 min before the end of surgery. Patient-controlled analgesia device was established for postoperative pain relief in all groups. Haemodynamic data and inspired sevoflurane concentration were recorded during the operation. Pain scores, total tramadol consumption, supplemental analgesic requirement and side effects were postoperatively evaluated. Demographic characteristics, duration of surgery and haemodynamic parameters were similar between the groups. Inspired sevoflurane concentration (%) and VAS scores were significantly lower in Group UR than those in Groups SR and T. Total tramadol consumption was significantly lower in Groups UR and SR than that in Group T. There was no significant difference in the incidence of side effects. This study demonstrates that ultrasound-guided rectus sheath block helps to provide the effective analgesia without any side effects compared with surgical rectus sheath block and intravenous tramadol for gynaecological surgery with Pfannenstiel incision.

Postoperative nausea and vomiting (PONV) affect approximately 80% of surgical patients and is associated with increased length of hospital stay and systemic costs. Preoperative and postoperative pain, anxiety and depression are also commonly reported. Recent evidence regarding their safety and effectiveness has not been synthesised. The aim of this systematic review is to evaluate the efficacy and safety of herbal medications for the treatment and prevention of anxiety, depression, pain and PONV in patients undergoing laparoscopic, obstetrical/gynaecological and cardiovascular surgical procedures. The following electronic databases will be searched up to 1 October 2016 without language or publication status restrictions: CENTRAL, MEDLINE, EMBASE, CINAHL, Web of Science and LILACS. Randomised clinical trials enrolling adult surgical patients undergoing laparoscopic, obstetrical/gynaecological and cardiovascular surgeries and managed with herbal medication versus a control group (placebo, no intervention or active control) prophylactically or therapeutically will be considered eligible. Outcomes of interest will include the following: anxiety, depression, pain, nausea and vomiting. A team of reviewers will complete title and abstract screening and full-text screening for identified hits independently and in duplicate. Data extraction, risk of bias assessments and evaluation of the overall quality of evidence for each relevant outcome reported will be conducted independently and in duplicate using the Grading of Recommendations Assessment Development and Evaluation classification system. Dichotomous data will be summarised as risk ratios; continuous data will be summarised as standard average differences with 95% CIs. This is one of the first efforts to systematically summarise existing evidence evaluating the use of herbal medications in laparoscopic, obstetrical/gynaecological and cardiovascular surgical patients. The findings of this review will be disseminated through peer-reviewed publications and conference presentations.

Sanders, Ari; Wilson, R Douglas

2015-11-01

The integration of simulation into residency programs has been slower in obstetrics and gynaecology than in other surgical specialties. The goal of this study was to evaluate the current use of simulation in obstetrics and gynaecology residency programs in Canada. A 19-question survey was developed and distributed to all 16 active and accredited obstetrics and gynaecology residency programs in Canada. The survey was sent to program directors initially, but on occasion was redirected to other faculty members involved in resident education or to senior residents. Survey responses were collected over an 18-month period. Twelve programs responded to the survey (11 complete responses). Eleven programs (92%) reported introducing an obstetrics and gynaecology simulation curriculum into their residency education. All respondents (100%) had access to a simulation centre. Simulation was used to teach various obstetrical and gynaecological skills using different simulation modalities. Barriers to simulation integration were primarily the costs of equipment and space and the need to ensure dedicated time for residents and educators. The majority of programs indicated that it was a priority for them to enhance their simulation curriculum and transition to competency-based resident assessment. Simulation training has increased in obstetrics and gynaecology residency programs. The development of formal simulation curricula for use in obstetrics and gynaecology resident education is in early development. A standardized national simulation curriculum would help facilitate the integration of simulation into obstetrics and gynaecology resident education and aid in the shift to competency-based resident assessment. Obstetrics and gynaecology residency programs need national collaboration (between centres and specialties) to develop a standardized simulation curriculum for use in obstetrics and gynaecology residency programs in Canada.

High Intensity Focused Ultrasound (HIFU) technology provides a feasible method of achieving thermal coagulation during surgical procedures. One of the potential clinical benefits of HIFU can induce immediate hemostasis without suturing. The objective of this study was to investigate the efficiency of a HIFU system for blood coagulation on severe vascular injury. ngHIFU treatment was implemented immediately after bleeding in artery. The ultrasound probe was made of piezoelectric material, generating a central frequency of 2.0 MHz as well as an ellipsoidal focal spot of 2 mm in lateral dimension and 10 mm in axial dimension. Acoustic coagulation was employed on a perfused chicken artery model in vitro. A surgical incision (1 to 2 mm long) was made with a scapel on the arterial wall, and heparinized autologous blood was made to leak out from the incision with a syringe pump. A total of 5 femoral artery incisions was treated with the HIFU beam. The intensity of 4500 W/cm2 at the focus was applied for all treatments. Complete hemostasis was achieved in all treatments, along with the treatment times of 25 to 50 seconds. The estimated intraoperative blood loss was from 2 to 5 mL. The proposed HIFU system may provide an effective method for immediate blood coagulation for arteries and veins in clinical applications.

To describe our technique of lenticule edge identification in small-incision lenticule extraction using the "meniscus sign" to prevent lenticule misdissection. Femtosecond laser application for small-incision lenticule extraction was performed. A "double ring" was visible, signifying the edge of the cap cut (outer ring) and lenticule cut (inner ring). The anterior and posterior lamellar planes were delineated in 2 different directions. During creation of the posterior lamellar channel, the lenticule edge was slightly pushed away from the surgeon to create a gap between the inner ring (diameter of the lenticule cut) and the lenticule edge. The lenticule edge assumed a frilled wavy appearance, and the meniscus sign was observed as a gap between the lenticule edge and the inner ring. The meniscus-shaped gap served as a landmark to identify the lenticule edge, and the relationship between the frilled lenticule edge and surgical instruments further acted as a guide to identify the correct plane of dissection. This technique was successfully undertaken in 50 eyes of 25 patients. The meniscus sign was observed in all cases, and no case had cap lenticular adhesions. The meniscus sign helps to identify the lenticule edge and correct dissection planes and provides a visual landmark during the entire surgical procedure.

In the sub-Saharan African setting, laparotomy for salpingectomy is the common method of treatment for ectopic pregnancy (EP). The objective of this retrospective study was to find out how common EP is treated conservatively in the Yaounde Gynaeco-Obstetric and Paediatric Hospital, Cameroon. Of the 281 patient files analysed, 126 patients (44.8%) were treated conservatively and successfully for EP. Of these, 86 (68.2%) had received conservative surgical treatment while 40 (31.8%) had non-surgical treatment. Salpingostomy was the conservative surgery for 79.1% of the cases. According to the publications available for the sub-Saharan setting, the rate of conservative management of EP at the Yaounde Gynaeco-Obstetric and Paediatric Hospital, Cameroon is high. We recommend that this rate should be improved so that, eventually, the conservative treatment methods of EP become routine.

To study the social integration of women supported in the urology department of the University Hospital of Point G for obstetric urogenital fistula. Prospective study conducted over a period of 13 months from June 2008 to June 2009 in the Department of Urology at the University Hospital of Point G. The study included all patients who have been operated on at least twice for obstetric fistula genitourinary. Records of surgical, medical records and tracking sheets for each patient were the media database. Situation before treatment: before surgical treatment, 76.92% of patients were rejected by their spouses. The family attended the patient in 84.62% of cases. Situation after treatment: after treatment, 90.31% of women with fistula lived in the matrimonial home or family. The resumption of business activity was announced by 11.2% of patients. Among the women, 93.7% participated in housework. The number of patient intervention ranged from two to five. Healing (fistula closed and no sphincter dysfunction) was complete in 50% of cases. Among the women, 11.54% had sphincter dysfunction after closure of the fistula, which makes a total of fistula closed more than 61% after at least two attempts. The urogenital fistulas are not a fatal disease but is a real handicap for women who suffer to conduct a socio-cultural and economic mainstream. Generally excluded from the ongoing operations of the company, these women are more integrated after successful surgical treatment of the fistula. Copyright © 2013 Elsevier Masson SAS.

This study was aimed to detect the positions of mental canal and incisive nerve canal as well as the prolongation of mandibular canal in interforaminal region in Chinese population to supply the reference data of the surgical safe zone in chin for clinicians. A total of 80 formalin-fixed semi-mandibles of Chinese adult cadavers were dissected, the positions and courses of mental canal and incisive nerve canal as well as the prolongation of mandibular canal in interforaminal region were measured. The mental foramina were present in all cases (100 %), and most of them were located below 2nd premolar (58.75 %). Accessory mental foramina were observed in 5 %. The anterior end of mandibular canal, extending along the course of 7.37 ± 1.10 mm above the lower border of mandible to interforaminal region about 3.54 ± 0.70 mm medial to the mental foramen, most often ended below between the two premolars (73.75 %), where it continued as the incisive nerve canal (100 %) and the mental canal (96.25 %). Mental canal, with the wall formed by compact bone, being 2.60 ± 0.60 mm in diameter and 4.01 ± 1.20 mm in length, opened into mental foramen. Incisive nerve canal, with the wall formed by thin compact bone and/or partly or completely by spongy bone, being 1.76 ± 0.27 mm in diameter and 24.87 ± 2.23 mm in length, extended to the incisor region along the course of 9.53 ± 1.43 mm above the lower border of mandible, and most often ended below the lateral incisor (70.00 %). This research recommended for chin operations in Chinese population: the surgical safe zone could be set in the region about over 4 mm anterior to the mental foramen, and over 12 mm above inferior border of mandible for anterior alveolar surgery, or within 9 mm above inferior border of mandible for genioplasty.

To determine the reproducibility of classifying uterine fibroids using the 2011 International Federation of Gynecology and Obstetrics (FIGO) staging system. The present retrospective cohort study included patients presenting for the treatment of symptomatic uterine fibroids at the Gynecology Fibroid Clinic at Mayo Clinic, Rochester, USA, between April 1, 2013 and April 1, 2014. Magnetic resonance imaging of fibroid uteri was performed and the images were independently reviewed by two academic gynecologists and two radiologists specializing in fibroid care. Fibroid classifications assigned by each physician were compared and the significance of the variations was graded by whether they would affect surgical planning. There were 42 fibroids from 23 patients; only 6 (14%) fibroids had unanimous classification agreement. The majority (36 [86%]) had at least two unique answers and 4 (10%) fibroids had four unique classifications. Variations in classification were not associated with physician specialty. More than one-third of the classification discrepancies would have impacted surgical planning. FIGO fibroid classification was not consistent among four fibroid specialists. The variation was clinically significant for 36% of the fibroids. Additional validation of the FIGO fibroid classification system is needed. © 2017 International Federation of Gynecology and Obstetrics.

Surgical Site Infiltration for Abdominal Surgery: A Novel Neuroanatomical-based Approach

PubMed Central

Janis, Jeffrey E.; Haas, Eric M.; Ramshaw, Bruce J.; Nihira, Mikio A.; Dunkin, Brian J.

2016-01-01

Background: Provision of optimal postoperative analgesia should facilitate postoperative ambulation and rehabilitation. An optimal multimodal analgesia technique would include the use of nonopioid analgesics, including local/regional analgesic techniques such as surgical site local anesthetic infiltration. This article presents a novel approach to surgical site infiltration techniques for abdominal surgery based upon neuroanatomy. Methods: Literature searches were conducted for studies reporting the neuroanatomical sources of pain after abdominal surgery. Also, studies identified by preceding search were reviewed for relevant publications and manually retrieved. Results: Based on neuroanatomy, an optimal surgical site infiltration technique would consist of systematic, extensive, meticulous administration of local anesthetic into the peritoneum (or preperitoneum), subfascial, and subdermal tissue planes. The volume of local anesthetic would depend on the size of the incision such that 1 to 1.5 mL is injected every 1 to 2 cm of surgical incision per layer. It is best to infiltrate with a 22-gauge, 1.5-inch needle. The needle is inserted approximately 0.5 to 1 cm into the tissue plane, and local anesthetic solution is injected while slowly withdrawing the needle, which should reduce the risk of intravascular injection. Conclusions: Meticulous, systematic, and extensive surgical site local anesthetic infiltration in the various tissue planes including the peritoneal, musculofascial, and subdermal tissues, where pain foci originate, provides excellent postoperative pain relief. This approach should be combined with use of other nonopioid analgesics with opioids reserved for rescue. Further well-designed studies are necessary to assess the analgesic efficacy of the proposed infiltration technique. PMID:28293525

Cold Plasma Welding System for Surgical Skin Closure: In Vivo Porcine Feasibility Assessment.

2016-09-29

Cold plasma skin welding is a novel technology that bonds skin edges through soldering without the use of synthetic materials or conventional wound approximation methods such as sutures, staples, or skin adhesives. The cold plasma welding system uses a biological solder applied to the edges of a skin incision, followed by the application of cold plasma energy. The objectives of this study were to assess the feasibility of a cold plasma welding system in approximating and fixating skin incisions compared with conventional methods and to evaluate and define optimal plasma welding parameters and histopathological tissue response in a porcine model. The cold plasma welding system (BioWeld1 System, IonMed Ltd, Yokneam, Israel) was used on porcine skin incisions using variable energy parameters. Wound healing was compared macroscopically and histologically to incisions approximated with sutures. When compared to sutured skin closure, cold plasma welding in specific system parameters demonstrated comparable and favorable wound healing results histopathologically as well as macroscopically. No evidence of epidermal damage, thermal or otherwise, was encountered in the specified parameters. Notably, bleeding, infection, and wound dehiscence were not detected at incision sites. Skin incisions welded at extreme energy parameters presented second-degree burns. Implementation of cold plasma welding has been shown to be feasible for skin closure. Initial in vivo results suggest cold plasma welding might provide equal, if not better, healing results than traditional methods of closure.

The incidence of fascial dehiscence and incisional hernia after two methods for abdominal wound closure (rectus sheath relaxation incisions and conventional mass closure) was studied in a randomized prospective clinical trial in a consecutive series of 100 patients undergoing midline laparotomy for peritonitis. The two groups were well matched for etiologies of peritonitis, the surgical procedures performed, and the presence of known risk factors for fascial dehiscence. Fifty patients each were randomized either to the conventional continuous mass closure procedure or the rectus sheath relaxation incision technique (designed to increase wound elasticity and decrease tension in the suture line) using identical polypropylene sutures. The incidence of postoperative complications such as duration of ileus, chest infection, and wound infection were not statistically different between the two groups. The intensity of postoperative pain in the rectus sheath relaxation incision group was significantly less. The incidence of wound hematoma was significantly increased in the rectus sheath relaxation incision group. The incidences of fascial dehiscence (16% vs,28%; p < 0.05) and incisional hernia (18% vs, 30%; p < 0.05) were significantly lower after rectus sheath relaxation incisions compared to conventional mass closure. Closure of the midline laparotomy wound in cases of peritonitis using the rectus sheath relaxation technique is safe and less painful, provides increased wound elasticity and decreased tension on the suture line, and significantly decreases the incidence of wound dehiscence.

Force modeling for incisions into various tissues with MRF haptic master

This study proposes a new model to predict the reaction force that occurs in incisions during robot-assisted minimally invasive surgery. The reaction force is fed back to the manipulator by a magneto-rheological fluid (MRF) haptic master, which is featured by a bi-directional clutch actuator. The reaction force feedback provides similar sensations to laparotomy that cannot be provided by a conventional master for surgery. This advantage shortens the training period for robot-assisted minimally invasive surgery and can improve the accuracy of operations. The reaction force modeling of incisions can be utilized in a surgical simulator that provides a virtual reaction force. In this work, in order to model the reaction force during incisions, the energy aspect of the incision process is adopted and analyzed. Each mode of the incision process is classified by the tendency of the energy change, and modeled for realistic real-time application. The reaction force model uses actual reaction force information with three types of actual tissues: hard tissue, medium tissue, and soft tissue. This modeled force is realized by the MRF haptic master through an algorithm based on the position and velocity of a scalpel using two different control methods: an open-loop algorithm and a closed-loop algorithm. The reaction forces obtained from the proposed model are compared with a desired force in time domain.

Although surgical outcomes of total arch replacement have improved, the strategy for extended arch aneurysms remains controversial. We have applied the L-incision approach (combination of left anterior thoracotomy and upper half-median sternotomy) for total arch replacement for single-stage repair of extensive arch aneurysms. We retrospectively reviewed the operative outcomes of patients who underwent total arch or extended total arch replacement for degenerative aneurysms from 1999 to 2010. Operations were performed via median sternotomy in 47 patients (M group) and the L-incision approach was used in 38 patients (L group). Through the L-incision approach, we were able to complete distal anastomosis below the pulmonary hilus. The L-incision approach has advantages of reducing selective antegrade cerebral perfusion and lower body circulatory arrest times compared with the M group. Recurrent laryngeal nerve palsy and renal dysfunction were less frequent in the L group than those in the M group. Respiratory dysfunction and wound infection were similar between the groups. Hospital mortalities were 5.3% in the L group and 6.4% in the M group. The L-incision approach has similar or better postoperative outcomes compared with the median sternotomy approach. This approach could be useful for single-stage extended total arch replacement with relatively low risk.

Surgical site infiltration and transversus abdominis plane (TAP) blocks are commonly used to improve pain relief after lower abdominal surgery. This randomized, observer-blinded study was designed to compare the analgesic efficacy of TAP blocks with surgical site infiltration in patients undergoing open total abdominal hysterectomy via a Pfannenstiel incision. Patients were randomized to receive either bilateral ultrasound-guided TAP blocks using bupivacaine 0.5% 20 mL on each side (n = 30) or surgical site infiltration with liposomal bupivacaine 266 mg diluted to 60 mL injected in the preperitoneal, subfascial, and subcutaneous planes (n = 30). The remaining aspects of the perioperative care were standardized. An investigator blinded to the group allocation documented pain scores at rest and with coughing, opioid requirements, nausea, vomiting, and rescue antiemetics in the postanesthesia care unit and at 2, 6, 12, 24, and 48 hours postoperatively. The primary outcome measure was pain scores on coughing at 6 hours postoperatively. One patient in each group was excluded from the analysis because of reoperation within 24 hours in the TAP block group and change of incision type in the infiltration group. The pain scores at rest and with coughing were significantly lower in the surgical site infiltration group at all postoperative time points (P < 0.0001) except at rest in the postanesthesia care unit. The opioid requirements between 24 and 48 hours were significantly lower in the infiltration group (P = 0.009). The nausea scores, occurrence of vomiting, and need for rescue antiemetics were similar. Surgical site infiltration provided superior pain relief at rest and on coughing, as well as reduced opioid consumption for up to 48 hours. Future studies need to compare TAP blocks with liposomal bupivacaine with surgical site infiltration with liposomal bupivacaine.

Obstetric fistula is a preventable and treatable condition predominately affecting women in low-income countries. Understanding the social context of obstetric fistula may lead to improved prevention and treatment. This study investigated social experiences of women with obstetric fistula seeking treatment at Mulago Hospital in Kampala, Uganda. A descriptive study was conducted among women seeking treatment for obstetric fistula during a surgical camp in July 2011 using a structured questionnaire. Descriptive statistics were computed regarding sociodemographics, obstetric history, and social experience. Fifty-three women participated; 39 (73.58%) leaked urine only. Median age was 29 years (range: 17-58), and most were married or separated. About half (28, 47.9%) experienced a change in their relationship since acquiring obstetric fistula. More than half (27, 50.94%) acquired obstetric fistula during their first delivery, despite almost everyone (50, 94.3%) receiving antenatal care. The median years suffering from obstetric fistula was 1.25. Nearly every participant's social participation changed in at least one setting (51, 96.23%). Most women thought that a baby being too big or having kicked their bladder was the cause of obstetric fistula. Other participants thought health care providers caused the fistula (15, 32.61%; n = 46), with 8 specifying that the bladder was cut during the operation (cesarean section). Knowing someone with obstetric fistula was influential in pursuing treatment. The majority of participants planned to return to family (40, 78.43%; n = 51) and get pregnant after repair (35, 66.04%; n = 53). Study participants experienced substantial changes in their social lives as a result of obstetric fistula, and there were a variety of beliefs regarding the cause. The complex social context is an important component to understanding how to prevent and treat obstetric fistula. Further elucidation of these factors may bolster current efforts in prevention and holistic treatment. Copyright © 2017 Icahn School of Medicine at Mount Sinai. Published by Elsevier Inc.

Although predictors of laryngeal mask airway failure in adults have been elucidated, there remains a paucity of data regarding laryngeal mask airway failure in children. The authors performed a retrospective database review of all pediatric patients who received a laryngeal mask anesthetic at their institution from 2006 to 2010. Device brands were restricted to LMA Unique™ (Cardinal Health, Dublin, OH) and LMA Classic™ (LMA North America, San Diego, CA), and primary outcome was laryngeal mask failure, defined as any airway event requiring device removal and tracheal intubation. Potential risk factors were analyzed with both univariate and multivariate techniques and included medical history, physical examination, surgical, and anesthetic characteristics. Of the 11,910 anesthesia cases performed in the study, 102 cases (0.86%) experienced laryngeal mask failure. Common presenting features of laryngeal mask failures included leak (25%), obstruction (48%), and patient intolerance such as intractable coughing/bucking (11%). Failures occurred before incision in 57% of cases and after incision in 43%. Independent clinical associations included ear/nose/throat surgical procedure, nonoutpatient admission status, prolonged surgical duration, congenital/acquired airway abnormality, and patient transport. The findings of the study support the use of the LMA Unique™ and LMA Classic™ as reliable pediatric supraglottic airway devices, demonstrating relatively low failure rates. Predictors of laryngeal mask airway failure in the pediatric surgical population do not overlap with those in the adult population and should therefore be independently considered.

Obstetric fistula is a debilitating birth injury that affects an estimated 2-3 million women globally, most in sub-Saharan Africa and Asia. The urinary and/or fecal incontinence associated with fistula affects women physically, psychologically and socioeconomically. Surgical management of fistula is available with clinical success rates ranging from 65-95 %. Previous research on fistula repair outcomes has focused primarily on clinical outcomes without considering the broader goal of successful reintegration into family and community. The objectives for this study are to understand the process of family and community reintegration post fistula surgery and develop a measurement tool to assess long-term success of post-surgical family and community reintegration. This study is an exploratory sequential mixed-methods design including a preliminary qualitative component comprising in-depth interviews and focus group discussions to explore reintegration to family and community after fistula surgery. These results will be used to develop a reintegration tool, and the tool will be validated within a small longitudinal cohort (n = 60) that will follow women for 12 months after obstetric fistula surgery. Medical record abstraction will be conducted for patients managed within the fistula unit. Ethical approval for the study has been granted. This study will provide information regarding the success of family and community reintegration among women returning home after obstetric fistula surgery. The clinical and research community can utilize the standardized measurement tool in future studies of this patient population.

Gebhart, John B; Schmitt, Jennifer J

2016-08-01

Management of the constricted or obliterated vagina demands an understanding and recognition of the potential etiologies leading to this presentation. A thorough and comprehensive medical and surgical review is required to arrive at an accurate diagnosis, which then will guide medical or surgical intervention. It is paramount to recognize when underlying medical conditions are contributing to these conditions and to begin medical therapy; failure to do so will often yield suboptimal results. When these conditions arise after surgical interventions, compensatory surgical techniques that correct upper and lower vaginal strictures or obliteration include incision through the stricture, vaginal advancement, Z-plasty, skin grafts, perineal flaps, and abdominal flaps and grafts. Postoperative surveillance and dilation are critical to optimize long-term success.

The objectives of this study were to calculate the frequency of hysterectomies at the Conakry university hospitals (Donka Hospital and Ignace Deen Hospital), describe the women's social, demographic, and clinical characteristics, and identify the key indications, the surgical techniques used, and the prognosis. This was a 2-year descriptive study, retrospective for the first year (May 2011-April 2012) and prospective for the second (May 2012-April 2013), of 333 consecutive hysterectomies performed in the obstetrics and gynecology departments of these two hospitals. Hysterectomy is one of the surgical procedures most commonly performed in these departments (following cesarean deliveries), with frequency of 4.4% interventions. The profile of the women undergoing this surgery was that of a woman aged younger than 49 years (61%), married (75.7%), multiparous (33%), of childbearing age (61%), and with no history of abdominal or pelvic surgery (79.6%). Nearly all hysterectomies were total (95%, compared with 5% subtotal; the approach was abdominal in 82.25% of procedures and vaginal in 17.75%. The most common indication for surgery was uterine fibroids (39.6%), followed by genital prolapse (22.2%), and obstetric emergencies (17.8%). The average duration of surgery was 96 minutes for abdominal and 55 minutes for vaginal hysterectomies. The principal intraoperative complication was hemorrhage (12.31%), and the main postoperative complication parietal suppuration (21.02%). The average length of hospital stay was 10.3 days for abdominal hysterectomies and 7.15 days for vaginal procedures. We recorded 14 deaths for a lethality rate of 4.2%; most of these deaths were associated with hemorrhagic shock during or after an obstetric hysterectomy (93%). Hysterectomy remains a common intervention in developing countries. Its indications are common during the pregnancy and postpartum period, with high morbidity and mortality rates. Improving obstetric coverage could reduce its indications.

The efficacy of antibiotics in preventing surgical site infections (SSIs) depends on the timing of administration relative to the start of surgery. However, currently, both the timing of and recommendations for administration vary substantially. To determine how the economic value from the hospital perspective of preoperative antibiotics varies with the timing of administration for orthopaedic procedures. Computational decision and operational models were developed from the hospital perspective. Baseline analyses looked at current timing of administration, while additional analyses varied the timing of administration, compliance with recommended guidelines, and the goal time-interval. Beginning antibiotic administration within 0-30 min prior to surgery resulted in the lowest costs and SSIs. Operationally, linking to a pre-surgical activity, administering antibiotics prior to incision but after anaesthesia-ready time was optimal, as 92.1% of the time, antibiotics were administered in the optimal time-interval (0-30 min prior to incision). Improving administration compliance from 80% to 90% for this pre-surgical activity results in cost savings of $447 per year for a hospital performing 100 orthopaedic operations a year. This study quantifies the potential cost-savings when antibiotic administration timing is improved, which in turn can guide the amount hospitals should invest to address this issue.

The biatrial approach has been the classic means of access for left atrial myxoma resection. Increased surgical experience led cardiac surgeons to favour the uniatrial approach to reduce incisions and achieve adequate exposure. In this study, two unilateral surgical approaches were compared in 18 consecutive left atrial myxoma cases. Patients were divided into two groups according to the surgical approach: left atriotomy (group 1, n = 9) and right atriotomy trans-septal approach (group 2, n = 9). Comparison criteria included pre- and post-operative functional capacity, cardiac rhythm, left ventricular ejection fraction, pulmonary artery pressure, left atrial dimensions, cardiopulmonary bypass time, aortic cross-clamp time, drainage over 48 h post-operatively, units of blood transfused, extubation time and length of stay in the intensive care unit and hospital. No significant between-group difference was observed in any criteria except aortic cross-clamp time, which was significantly longer in group 2 than in group 1. No recurrence of myxoma occurred in either group for the 15 patients followed up. Right atrial trans-septal incision appears to be as safe and effective as the left atriotomy approach for left atrial myxoma resection.

We developed a new surgical model of penile girth enhancement in dog, with minimal damage, fewer complications, and high success rate, to enable the experimental investigation of penile implants. We obtained materials for penile girth enhancement by processing the pericardium and blood vessel wall collected from pigs. Incisions were made at the penile bulb for the implantation of the materials, and facilitate observation and data collection, based on the anatomical features of dog's penis. We measured the girth of the flaccid penis before and after the operation, and erectile function at 1-month postoperation. In addition to evaluation of recovery from the incision and local pathological changes, ultrasonic examination was performed to monitor the long-term changes associated with implantation. The mean girth of the flaccid penis significantly increased from 7.37±0.40 cm before the operation, to 8.70±0.56 cm postoperation. Dogs resumed normal mating at 1 month after the operation, without any significant change in the mating time. Ultrasonic examination clearly illustrated the implants, and helped in the measurement of the distance between the materials and the baculum. Chinese Rural dog is a promising animal model for penile girth enhancement surgery. The findings demonstrated that surgical implantation into penile bulb was associated with less damage, faster postoperative recovery, and higher success. For the first time, ultrasonic examination provided objective data on the surgical outcomes of penile girth enhancement.

This is the first population-based analysis of inpatient salivary gland surgery across Germany. Nationwide Diagnosis-Related Groups (DRG) statistics for 2007 to 2011 were analyzed regarding indications for salivary gland surgery based on ICD-10 codes. Age specific surgery rates were calculated for both sexes. Inpatient salivary gland surgical rates in 2007-2011 amounted for incisions (OPS [Classification of Operations and Procedures] code 5-260) 1.43 per 100 000 population, for excisions (5-261) 2.06 per 100 000, for salivary gland resections (5-262) 2.06 per 100 000, and for external incisions (5-270) 0.43 per 100 000. Regarding the mentioned four OPS codes, the surgical rates for benign tumors accounted to 10.08 per 100 000, for sialadenitis (without sialoliths) to 4.00 per 100 000, for malignant tumors to 3.90 per 100 000, and for sialolithiasis to 2.09 per 100 000. The increase of surgical rates from 2007 to 2011 was significant for malignant and benign tumors as well as for salivary stones. The surgical rates were highest for patients>60 years. Especially surgery for malignant tumors was more frequent than expected. In spite of the introduction of minimal invasive technique the rates for salivary gland resections in case of sialadenitis or sialolithiasis still seem to be high. © Georg Thieme Verlag KG Stuttgart · New York.

Axillary bromhidrosis has a strong negative effect on one's social life. A high success rate and few complications are criteria for a surgical treatment. The objective of this study was to evaluate a new surgical treatment modality for bromhidrosis: subcutaneous scissor with micropore. Twenty patients with bromhidrosis were treated. Patients were placed in a supine position with their treated arms abducted to 110°. After injection of 60 mL of tumescent solution into each axilla, one small incision was made at the middle axillary of the hair-bearing area. The whole hair-bearing skin was undermined at the level of the superficial fat to obtain adequate skin eversion. The flaps were everted to offer full exposure of the apocrine glands, and meticulous excision of each gland was performed. Both sides were punctured with scalpel. The micropore was used for drainage, and whose width was just 3 mm. Finally, the incisions were re-approximated, and bulky compressive dressings were applied to the area for 72 hours. Of the 40 axillae (20 patients), 34 (85.0%) showed excellent results, and six (15.0%) had good results. Malodor was significantly decreased. There were no serious complications. This technique can produce excellent results with a lower complication rate than most other surgical modalities and can be performed without costly equipment. © 2017 Wiley Periodicals, Inc.

Background: Tendon transfers can be a surgical treatment option in managing younger, active patients with massive irreparable rotator cuff tears. The purpose of this article is to provide an overview of the use of tendon transfers to treat massive irreparable rotator cuff tears and to summarize clinical outcomes. Methods: A selective literature search was performed and personal surgical experiences are reported. Results: Latissimus dorsi transfers have been used for many years in the management of posterosuperior rotator cuff tears with good reported clinical outcomes. It can be transferred without or with the teres major (L’Episcopo technique). Many surgical techniques have been described for latissimus dorsi transfer including single incision, double incision, and arthroscopically assisted transfer. Transfer of the pectoralis major tendon is the most common tendon transfer procedure performed for anterosuperior rotator cuff deficiencies. Several surgical techniques have been described, however transfer of the pectoralis major beneath the coracoid process has been found to most closely replicate the force vector that is normally provided by the intact subscapularis. Conclusion: Tendon transfers can be used successfully in the management of younger patients with massive irreparable rotator cuff tears and minimal glenohumeral arthritis. Improvements in clinical outcomes scores and range of motion have been demonstrated. This can delay arthroplasty, which is of particular importance for younger patients with high functional demands.

To compare the efficacy of correcting myopic astigmatism with femtosecond laser small-incision lenticule extraction (SMILE, Carl Zeiss Meditec AG) versus laser-assisted subepithelial keratectomy (LASEK). The study was conducted at the Ophthalmology Department, Eye and ENT Hospital, Shanghai, China. A retrospective, cross-sectional study. This study included patients who underwent small-incision lenticule extraction or LASEK for the correction of myopia and myopic astigmatism. Preoperative and 6-month postoperative astigmatism values were analyzed. The efficacies of the 2 surgeries to correct astigmatism were compared. A total of 180 right eyes of 180 patients (small-incision lenticule extraction: n = 113, LASEK: n = 67) were included. No significant difference was found between the 2 groups in the preoperative astigmatism (small-incision lenticule extraction: 1.16 ± 0.85D, LASEK: 1.16 ± 0.83D, P > .05) or the postoperative astigmatism (small-incision lenticule extraction: 0.35 ± 0.37D; LASEK: 0.31 ± 0.42D, P > .05), determined by manifest refraction. No significant difference was found between the 2 groups in surgically induced astigmatism vector (small-incision lenticule extraction: 1.13 ± 0.83D, LASEK: 1.01 ± 0.65D, P > .05). The correction index was higher for the small-incision lenticule extraction group (1.05 ± 0.53) than for the LASEK group (0.95 ± 0.21, P = .045). The postoperative astigmatism was significantly higher for the small-incision lenticule extraction group when the preoperative astigmatism was 1.0 D or less (small-incision lenticule extraction: 0.26 ± 0.30D, LASEK: 0.12 ± 0.20D, P = .007) and lower for the small-incision lenticule extraction group when the preoperative astigmatism was more than 2.0 D (small-incision lenticule extraction: 0.48 ± 0.37D, LASEK: 0.89 ± 0.46D, P = .002). An adjustment of nomograms for correcting low astigmatism (≤1.0 D) by small-incision lenticule extraction is suggested due to the tendency toward overcorrection, whereas a nomogram adjustment for tissue-saving ablation profile is needed for the correction of high astigmatism (>2.0 D) by LASEK due to the tendency toward undercorrection.

Background The purpose of this study is to demonstrate the feasibility of an innovative technique for the surgical management of rectal cancer: trans anal minimally invasive surgery assisted low anterior resection with total mesorectal excision (TAMIS assisted LAR TME) in a cadaver model. Trans anal endoscopic low anterior resection via natural orifice translumenal endoscopic surgery (NOTES) has been reported in cadaveric series using rigid trans anal endoscopic platforms. This procedure has not been described using a combination of a single incision laparoscopy and TAMIS soft trans anal endoscopic platform. Herein, we describe the first cadaveric series of TAMIS assisted single incision laparoscopic LAR with TME. Methods TAMIS assisted laparoscopic single incision LAR with TME was successfully performed in 5 fresh male human cadavers. The procedure was performed using the mini-Gelpoint single incision platform and the Gelpoint Path TAMIS platform (Applied Medical, Rancho Santa Margarita, CA). The variables recorded were age, body mass index (BMI in kg/m2), operative time, complications, and specimen length. The grade of the TME was determined by evaluation of the specimen by photo documentation by a gastrointestinal pathologist. Results All cadavers were male with a mean age of 71 +/− 8 years and mean BMI of 28 +/− 3 kg/m2. The mean operative time was 200 +/− 55 minutes (range 128 – 249 min). The quality of the TME was Grade I (complete) with intact mesorectum in all five cases. The mean specimen length was 36.8 +/− 3.4 cm. Intra-operative complications included one bowel injury and one splenic capsular tear. Conclusions TAMIS assisted laparoscopic LAR with TME is feasible in this pre-clinical cadaveric series. We have also demonstrated that a high quality TME can be achieved with this technique. Trans anal endoscopic techniques employed to perform total mesorectal dissection may revolutionize the surgical management of rectal cancer. However, phase II clinical trials are needed to further evaluate the oncologic safety and surgical outcomes of trans anal endoscopic TME using various platforms prior to widespread application of this new technique.

[Femtosecond laser in cataract surgery. A critical appraisal].

PubMed

Menapace, R M; Dick, H B

2014-01-01

The use of femtosecond lasers (FSL) is increasingly spreading in cataract surgery. Potential advantages over standard manual cataract surgery are the superior precision of corneal incisions and capsular openings as well as the reduction of ultrasound energy for lens nucleus work-up. Exact positioning and dimensioning of the anterior capsular opening should help reduce decentration and tilt of the intraocular lens (IOL) optics and thus achieve better target refraction. Together with the possibility to correct low-grade corneal astigmatism by precise arcuate incision, FSL technology is expected to convert cataract surgery from a purely curative into a refractive procedure. Apart from own experiences this review article critically analyses the pertinent literature published so far as well as congress presentations and personal reports of other FSL surgeons. The advantages and disadvantages are scrutinized with regard to their impact on the surgical and refractive results and compared with those experienced by the authors with manual cataract surgery over several decades. Economic and healthcare political aspects are also addressed. The use of FSL surgery improves the precision and reproducibility of corneal incisions and the capsular opening and reduces the amount of ultrasound energy required for lens nucleus work-up. However, the clinical benefits must be put into perspective due to the subsequent surgical manipulation of the incisions (during lens emulsification, aspiration and IOL injection), the lacking possibility to visualize the crystalline lens equator as the reference for correct capsulotomy centration and the relativity of ultrasound energy consumption on the corneal endothelial trauma. This is of particular relevance against the background of the significantly higher costs. Conversely, tears of the anterior capsule edge which, apart from interfering with correct IOL positioning, may entail serious complications presently occur more frequently with all FSL instruments. From the economic and healthcare political viewpoint, thought should be given to the possible acquisition of the cataract surgical business by the industry or investors, as cataract surgery is a high-volume standardized procedure with enormous future potential. This could fundamentally change our currently decentralized and individualized structures and subsequently the steam of patient and make surgeons largely dependent or superfluous.

To compare blade cultures in surgery for closed fracture using a single or double blade technique to determine whether the current practice of double blade technique is justified. 155 men and 29 women aged 20 to 60 (mean, 35) years who underwent surgery for closed fracture with healthy skin at the incision site were included. Patients were block randomised to the single (n=92) or double (n=92) blade technique. Blades were sent for bacteriological analysis. Outcome measures were early surgical site infection (SSI) within 30 days and cultures from the blades. The 2 groups were comparable in baseline characteristics. In the single blade group, 6 surgical blades and 2 control blades showed positive cultures; 4 patients developed SSI, but only one had a positive culture from the surgical blade (with different organism isolated from the wound culture). In the double blade group, 6 skin blades, 7 deep blades, and 0 control blade showed positive culture; only 2 patients had the same bacteria grown from both skin and deep blade. Five patients developed SSI, but only one patient had a positive culture from the deep blade (with different organism isolated from the wound culture). The difference in incidence of culture-positive blade or SSI between the 2 groups was not significant. The relative risk of SSI in the single blade group was 0.8. Positive blade culture was not associated with SSI in the single or double blade group. The practice of changing blade following skin incision has no effect on reducing early SSI in surgery for closed fracture in healthy patients with healthy skin.

Accessory breasts have received little attention in the surgical fields, although the condition is quite common in the female population, with 2-6% of women suffering from it. Its convexity and cyclic pain make women feel embarrassed and uncomfortable, so patients often desire surgical excision to improve their appearances and to remove the pain. A total of 967 patients who had been treated by an excision of accessory breast tissue with liposuction using minimal incision from September 2013 to Dec 2015 at the Damsoyu Hospital were analyzed for clinical factors retrospectively. All 967 patients were female. There were 514 (53.2%) unmarried patients and 453 (46.8%) married patients. The major clinical manifestation was the problem in the appearance with cyclic pain in both unmarried and married groups (82.7 vs. 87.9%). Three types of accessory breasts were observed: 779 (80.6%) breast tissue only in axillae, 182 (18.8%) breast tissue with accessory nipple, and 6 (0.6%) breast tissue with accessory nipple-areolar complex. The mean operation time was 58 min. All cyclic axillar pain in our cases was resolved after the operation. Postoperative complications developed in 160 patients (16.55%). Among them, seroma after operation was the most common (11.27%). In our study, 95.65% of the patients were satisfied with the cosmetic outcomes. The surgical excision of accessory breasts with liposuction through the minimal incision is a safe and effective method to make women feel comfortable in clinical manifestations and be satisfied with their cosmetic axillar line.

Parturients with super-morbid obesity, defined as body mass index greater than 50kg/m(2), represent a growing segment of patients who require anesthetic care for labor and delivery. Severe obesity and its comorbid conditions place the parturient and fetus at greater risk for pregnancy complications and cesarean delivery, as well as surgical and anesthetic complications. The surgical approach for cesarean delivery in these patients may require a supra-umbilical vertical midline incision due to a large pannus. The dense T4-level of spinal anesthesia can cause difficulties with ventilation for the obese patient during the procedure, which can be prolonged. Patients also may have respiratory complications in the postoperative period due to pain from the incision. We describe the anesthetic management of three parturients with body mass index ranging from 73 to 95kg/m(2) who had a cesarean delivery via a supra-umbilical vertical midline incision. Continuous lumbar spinal and low thoracic epidural catheters were placed in each patient for intraoperative anesthesia and postoperative analgesia, respectively. Continuous spinal catheters were dosed with incremental bupivacaine boluses to achieve surgical anesthesia. In one case, the patient required respiratory support with non-invasive positive pressure ventilation. Two cases were complicated by intraoperative hemorrhage. All patients had satisfactory postoperative analgesia with a thoracic epidural infusion. None suffered postoperative respiratory complications or postdural puncture headache. The use of a continuous lumbar spinal catheter and a low thoracic epidural provides several advantages in the anesthetic management of super-morbidly obese parturients for cesarean delivery.

GIRABENT-FARRÉS, M.

2018-01-01

Background We aimed to calculate the opportunity cost of the operating time to demonstrate that single incision laparoscopic cholecystectomy (SILC) is more expensive than classic laparoscopic cholecystectomy (CLC). Methods We identified studies comparing use of both techniques during the period 2008–2016, and to calculate the opportunity cost, we performed another search in the same period of time with an economic evaluation of classic laparoscopy. We performed a meta-analysis of the items selected in the first review considering the cost of surgery and surgical time, and we analyzed their differences. We subsequently calculated the opportunity cost of these time differences based on the design of a cost/time variable using the data from the second literature review. Results Twenty-seven articles were selected from the first review: 26 for operating time (3.138 patients) and 3 for the cost of surgery (831 patients), and 3 articles from the second review. Both techniques have similar operating costs. Single incision laparoscopy surgery takes longer (16.90min) to perform (p <0.00001) and this difference represents an opportunity cost of 755.97 € (cost/time unit factor of 44.73 €/min). Conclusions SILC costs the same as CLC, but the surgery takes longer to perform, and this difference involves an opportunity cost that increases the total cost of SILC. The value of the opportunity cost of the operating time can vary the total cost of a surgical technique and it should be included in the economic evaluation to support the decision to adopt a new surgical technique.

Rates of surgical site infections (SSIs) following groin incision for femoral artery exposure are much higher than expected of a clean operation. The morbidity and mortality is high, particularly with the use of prosthetic grafts. The vascular surgery population is at an increased risk of SSIs related to peripheral vascular disease (PVD), diabetes, obesity, previous surgery and presence of tissue loss. Negative pressure wound therapy (NPWT) dressings have been used on primarily closed incisions to reduce surgical site infections in other surgical disciplines. We have not come across any randomized controlled trials to support the prophylactic use of negative pressure wound therapy in high-risk vascular patients undergoing lower limb revascularization. In this single-center, prospective randomized controlled trial, patients scheduled for a lower limb revascularization requiring open femoral artery exposure who are at a high risk (BMI > 30 kg/m(2), previous femoral cutdown or Rutherford V or VI category for chronic limb ischemia) will be eligible for the study. A total of 108 groin incisions will be randomized to the use of a negative pressure wound device or standard adhesive gauze dressing. Patients will be followed in hospital and reassessed within the first 30 days postoperatively. The primary outcome is SSI within the first 30 days of surgery and will be determined using the intention-to-treat principle. Secondary outcomes include length of stay, emergency room visits, reoperation, amputation and mortality. A cost analysis will be performed. The trial is expected to define the role of NPWT in SSI prophylaxis for lower limb revascularization in high-risk vascular patients. The results of the study will be used to inform current best practice for perioperative care and the minimization of SSIs. NCT02084017 , March 2014.

Introduction: In Brazil, the main cause of death is the coronary heart disease and the surgical treatment applied in such cases is the Myocardial Revascularization (MR). Patients undergoing to MR through saphenous vein bypass development dehiscence in 10% of the cases. Dehiscence of surgical incision through Biomodulation treatment with Low Level Laser Therapy (LLLT) in patients who underwent to MR seems to be an unprecedented new therapy and a less invasive technique, which can benefit patients and Institutions, reducing costs. Methodology: It was analyzed 7 diabetic patients, mean age 51, 8 years old that post MR surgery presented dehiscence of the saphenectomy incision on lower limb with erithema, edema and pain. The wounds area varies from 2,2 until 34,8 cm and deep from 0,1 until 1,1 cm. It was used only Diode Laser C.W. (655 nm wavelength), Power = 25 mW, Time = 30 s, Fluence = 4 J/cm2 applied punctually around surgical wound's sore, by 2 cm distance. Results: It was observed granulated tissue all around the incision, as well as decreased inflammatory process, reduction fibrin and wound's size, besides analgesic effect since the first application. It was required in superficial wounds only 3 applications, while in the extensive wounds 8-10 applications were necessary. The LLLT has shown a remarkable role as a wound healing facilitated agent, reflecting the reduction of inflammatory process and improving analgesia. Conclusion: LLLT assisted dehiscence post saphenectomy showed a substantial improvement to the patient's quality of life, with a cost-effectiveness treatment that can benefit both patients and Institutions as an effective and less invasive therapy.

The clinical role of hyperoxia for preventing surgical site infection (SSI) remains uncertain because randomized controlled trials on this topic have reported disparate results. One of the principal reasons for this outcome may be that prior trials have entered heterogeneous populations of patients and a variety of procedures. The aim of our study was to assess the influence of hyperoxygenation on SSI using a homogeneous study population. From January 2004 to April 2013, we studied, in a randomized trial, 239 patients, who underwent open surgery for perforated peptic ulcer (PPU). The surgical procedure was performed through an upper abdominal midline incision, and closure of PPU was achieved by suture alone or in combination with an omental patch. Patients were assigned randomly to an oxygen/air mixture with a fraction of inspired oxygen (FiO2) of 30% (n = 120) or 80% (n = 119). Administration was commenced after induction of anesthesia and maintained for 6 hours after surgery. The overall incision infection rate was 38.4% (92 of 239): 61 patients (50.8%) had an infection in the 30% FiO2 group and 31 (26%) in the 80% FiO2 group (p < 0.05). The risk of SSI was 48% lower in the 80% FiO2 group (relative risk 0.51; 95% confidence interval [CI] 0.28-1.08) vs 30% FiO2. Supplemental 80% FiO2 during and for 6 h after open surgery for PPU, which reduces post-operative SSI, should be considered part of ongoing quality improvement activities related to surgical care, with few risks to the patient and little associated cost.

We have attempted to assess surgical experience among obstetric and gynaecology SpR's in Ireland using an anonymous on-line questionnaire. Trainees were asked to assess their own ability to perform a variety of general gynaecological procedures. There was a 97% response rate (29/33 trainees). There were 11 trainees who were in the final or penultimate year of the scheme. This group were analysed separately to assess competency rates in those approaching the end of the scheme. They were subdivided in to those who have completed one year in a general hospital doing pure gynaecology and those who have not. Approximately half of this group (6/11) had completed a pure gynaecology year. All of these trainees deemed themselves competent to perform all general gynaecological procedures listed, with the exception of trans-urethral tape procedures, for which 3/6 reported the requirement of direct supervision. Only 2/6 deemed themselves competent to perform a total laparoscopic hysterectomy. Year 4/5 trainees who had not completed a pure gynaecology year displayed significantly lower competency rates for most of the procedures. With the current changes in gynaecological practice, these results highlight the importance of dedicated gynaecological surgical training.

To compare the morphologic features and surgically induced astigmatism (SIA) between laser and manual clear corneal incisions (CCIs) after femtosecond laser-assisted cataract surgery. Eye Center, 2nd Affiliated Hospital, Medical College of Zhejiang University, Hangzhou, China. Prospective case series. Patients had femtosecond laser-assisted cataract surgery with a CCI created with the laser or manually after random allocation. The corrected distance visual acuity, corneal topography, and anterior segment optical coherence tomography were assessed at the 1-day, 1-week, 1-month, and 3-month follow-ups. The laser CCI group comprised 45 eyes and the manual CCI group, 48 eyes. The SIA was significantly lower in the manual CCI group than the laser CCI group at all visits (P < .05). At the 1-day and 1-week follow-ups, the mean CCI thickness was significantly smaller in the manual CCI group (P < .05). In the laser CCI group, the perpendicular linear distance between the external wound opening and the corneal vertex central line was statistically shorter than in the manual CCI group (P < .05). At 3 months, the SIA was correlated with the perpendicular linear distance with a Pearson correlation coefficient of -0.341 (P = .001). Femtosecond laser-created CCIs for cataract surgery caused more SIA than manually created CCIs, which could have resulted from inaccurate or uncertain corneal incision positioning of the femtosecond machine. Manual creation of CCIs is recommended in femtosecond laser-assisted cataract surgery until the locating system for the femtosecond laser incision is updated. Copyright © 2017 ASCRS and ESCRS.

Background Accumulating studies have suggested that remifentanil, the widely-used opioid analgesic in clinical anesthesia, can activate the pronociceptive systems and enhance postoperative pain. Glial cells are thought to be implicated in remifentanil-induced hyperalgesia. Electroacupuncture is a complementary therapy to relieve various pain conditions with few side effects, and glial cells may be involved in its antinociceptive effect. In this study, we investigated whether intraoperative electroacupuncture could relieve remifentanil-induced postoperative hyperalgesia by inhibiting the activation of spinal glial cells, the production of spinal proinflammatory cytokines, and the activation of spinal mitogen-activated protein kinases. Methods A rat model of remifentanil-induced postoperative hyperalgesia was used in this study. Electroacupuncture during surgery was conducted at bilateral Zusanli (ST36) acupoints. Behavior tests, including mechanical allodynia and thermal hyperalgesia, were performed at different time points. Astrocytic marker glial fibrillary acidic protein, microglial marker Iba1, proinflammatory cytokines, and phosphorylated mitogen-activated protein kinases in the spinal cord were detected by Western blot and/or immunofluorescence. Results Mechanical allodynia and thermal hyperalgesia were induced by both surgical incision and remifentanil infusion, and remifentanil infusion significantly exaggerated and prolonged incision-induced pronociceptive effects. Glial fibrillary acidic protein, Iba1, proinflammatory cytokines (interleukin-1β and tumor necrosis factor-α), and phosphorylated mitogen-activated protein kinases (p-p38, p-JNK, and p-ERK1/2) were upregulated after surgical incision, remifentanil infusion, and especially after their combination. Intraoperative electroacupuncture significantly attenuated incision- and/or remifentanil-induced pronociceptive effects, spinal glial activation, proinflammatory cytokine upregulation, and phosphorylated mitogen-activated protein kinase upregulation. Conclusions Our study suggests that remifentanil-induced postoperative hyperalgesia can be relieved by intraoperative electroacupuncture via inhibiting the activation of spinal glial cells, the upregulation of spinal proinflammatory cytokines, and the activation of spinal mitogen-activated protein kinases.

BACKGROUND Currently, safe and effective surgical treatment of malignant glaucoma is still under investigation. This study evaluated the clinical efficacy of ciliary ring incision combined with modified partial pars plana vitrectomy in the treatment of malignant glaucoma. The technique is particularly useful in the treatment of "phakic" patients with malignant glaucoma, especially those who wish to preserve the natural lens. MATERIAL AND METHODS We retrospectively analyzed 13 cases (16 eyes) of malignant glaucoma in which patients underwent ciliary ring incision combined with modified partial pars plana vitrectomy based on follow-up data collected from May 2004 to March 2017. The data we analyzed included postoperative best-corrected visual acuity(BCVA), intraocular pressure (IOP), anterior chamber depth (ACD), optic cup changes, and surgical complications; some patients underwent visual field tracking. The mean follow-up period was 33.1±10.6 (range, 19-46) months. RESULTS A statistically significant number of eyes had improved visual acuity 1 year after surgery compared with the preoperative difference (Z=-3.853, P=0.000). Increases in the mean anterior chamber depth and decreases in the mean IOP measured at the 1-week and the 1-year follow-ups were also statistically significant. There were no serious complications during the follow-up period. CONCLUSIONS Ciliary ring incision combined with modified partial pars plana vitrectomy for malignant glaucoma not only provided a clear and reliable intraoperative vitrectomy channel, but it also caused less disturbance of intraocular tissue structure and fewer complications. It also has the advantage of preserving the lens and avoiding further damage to the anatomy in the anterior segment of the eye.

Objective This study aimed to evaluate the effects of ultrasound-guided rectus sheath block in gynaecological surgery with Pfannenstiel incision. Methods After the approval of the ethics committee and the patients’ consent, 75 ASA I–II patients who were aged between 20 and 70 years and scheduled for a gynaecological surgery with Pfannenstiel incision were included in this study. After induction of general anaesthesia, patients were randomly divided into three groups. In Group UR patients (n=25), ultrasound-guided rectus sheath block with 0.25% levobupivacaine (0.2 mL kg−1) was performed. In Group SR patients (n=25), surgical rectus sheath block with 0.25% levobupivacaine (0.2 mL kg−1) was applied. In Group T (n=25) patients, tramadol (2 mg kg−1) was intravenously administered 30 min before the end of surgery. Patient-controlled analgesia device was established for postoperative pain relief in all groups. Haemodynamic data and inspired sevoflurane concentration were recorded during the operation. Pain scores, total tramadol consumption, supplemental analgesic requirement and side effects were postoperatively evaluated. Results Demographic characteristics, duration of surgery and haemodynamic parameters were similar between the groups. Inspired sevoflurane concentration (%) and VAS scores were significantly lower in Group UR than those in Groups SR and T. Total tramadol consumption was significantly lower in Groups UR and SR than that in Group T. There was no significant difference in the incidence of side effects. Conclusion This study demonstrates that ultrasound-guided rectus sheath block helps to provide the effective analgesia without any side effects compared with surgical rectus sheath block and intravenous tramadol for gynaecological surgery with Pfannenstiel incision.

Ojo, Oluwatosin J.; Carne, David; Guyton, Daniel

2012-01-01

Background and Objectives: To present our experience with a single-incision laparoscopic total colectomy, along with a literature review of all published cases on single-incision laparoscopic total colectomy. Methods: A total of 22 cases were published between 2010 and 2011, with our patient being case 23. These procedures were performed in the United States and United Kingdom. Surgical procedures included total colectomy with end ileostomy, proctocolectomy with ileorectal anastomosis, and total proctocolectomy with ileopouch-anal anastomosis. Intraoperative and postoperative data are analyzed. Results: Twenty-two of the 23 cases were performed for benign cases including Crohns, ulcerative colitis, and familial adenomatous polyposis. One case was performed for adenocarcinoma of the cecum. The mean age was 35.3 years (range, 13 to 64), the mean body mass index was 20.1 (range, 19 to 25), mean operative time was 175.9 minutes (range, 139 to 216), mean blood loss was 95.3mL (range, 59 to 200), mean incision length was 2.61cm (range, 2 to 3). Average follow-up was 4.6 months with 2 reported complications. Conclusions: Single-incision laparoscopic total colectomy is feasible and safe in the hands of an experienced surgeon. It has been performed for both benign and malignant cases. It is comparable to the conventional multi-port laparoscopic total colectomy. PMID:22906326

Childbirth can be a traumatic experience on the female body. Some techniques may be implemented to make the process smoother and decrease the potential lacerations that can occur. Episiotomies have been used by obstetricians and midwives to help make the fetal decent down the vaginal canal less turbulent. A physician must use his best judgment on when it is necessary to make this incision and what form of incision to make. Before making an incision one must understand the female external and internal anatomy and thoroughly comprehend the stages of birth to understand how and what complications can occur. Even though an episiotomy is a minor incision, it is still a surgical incision nonetheless and as with any form of surgery there are both risks and benefits that are to be considered. Nevertheless, episiotomies have proven to help ease births that are complicated by shoulder dystocia, prevent severe lacerations, and decrease the second stage of labor. The following comprehensive review provides a description of the female anatomy, as well as an extensive description of why, when, and how an episiotomy is done. Clin.

To compare postoperative vaginal incision separation and healing in patients undergoing posterior repair with perforated porcine dermal grafts with those that received grafts without perforations. Secondarily, the tensile properties of the perforated and non-perforated grafts were measured and compared. This was a non-randomized retrospective cohort analysis of women with stage II or greater rectoceles who underwent posterior repair with perforated and non-perforated porcine dermal grafts (Pelvicol(TM) CR Bard Covington, GA USA). The incidence of postoperative vaginal incision separation (dehiscence) was compared. A secondary analysis to assess graft tensile strength, suture pull out strength, and flexibility after perforation was performed using standard test method TM 0133 and ASTM bending and resistance protocols. Seventeen percent of patients (21/127) who received grafts without perforations developed vaginal incision dehiscence compared to 7% (5/71) of patients who received perforated grafts (p = 0.078). Four patients with vaginal incision dehiscence with non-perforated grafts required surgical revision to facilitate healing. Neither tensile strength or suture pull out strength were significantly different between perforated and non-perforated grafts (p = 0.81, p = 0.29, respectively). There was no difference in the flexibility of the two grafts (p = 0.20). Perforated porcine dermal grafts retain their tensile properties and are associated with fewer vaginal incision dehiscences.

Experience in the use of Single Incision Laparoscopic Surgery procedures and the persistent urge to improve the cosmetic effect have contributed to the introduction of mesh repair of an umbilical hernia by means of a small incision in the natural position of the umbilicus. The aim of the study was to present the surgical technique and assess its postoperative results. During the period between 24.08.2011 and 01.01.2013, twenty-three umbilical hernia repair operations with the use of a polypropylene mesh by means of a small incision in the natural position of the umbilicus were performed. The synthetic material was placed in the preperitoneal space. The wound was closed and the umbilicus was reconstructed simultaneously, in order to make the scar invisible. Cutaneous stitches were not used. The average duration of the operation was 49 minutes. In one case of an obese patient with coexisting linea alba dehiscence, hernia recurrence was observed. All wounds healed without complications. The cosmetic effect was very good. Based on the presented experience mesh repair of the umbilical hernia by means of a small incision in the natural position of the umbilicus contributes essential benefits, such as a very good cosmetic effect without consecutive increasing costs, as compared to standard treatment by means of an infraumbilical incision.

Many minimally invasive surgical procedures and assisting robotic systems have been developed to further minimize the number and size of incisions in the body surface. This paper presents a new idea combining the advantages of modular robotic surgery, single incision laparoscopic surgery and needlescopic surgery. In the proposed concept, modules carrying therapeutic or diagnostic tools are inserted in the abdominal cavity from the navel as in single incision laparoscopic surgery and assembled to 3-mm needle shafts penetrating the abdominal wall. A three degree-of-freedom robotic module measuring 16 mm in diameter and 51 mm in length was designed and prototyped. The performance of the three connected robotic modules was evaluated. A new idea of modular robotic surgery was proposed, and demonstrated by prototyping a 3-DOF robotic module. The performance of the connected robotic modules was evaluated, and the challenges and future work were summarized.

Single-incision laparoscopic surgery (SILS) aims to eliminate multiple port incisions. Although general operative principles of SILS are similar to conventional laparoscopic surgery, operative techniques are not standardized. This review aims to evaluate the current use of SILS published in the literature by examining the types of operations performed, techniques employed, and relevant complications and morbidity. This review considered a total of 94 studies reporting 1889 patients evaluating 17 different general surgical operations. There were 8 different access techniques reported using conventional laparoscopic instruments and specifically designed SILS ports. There is extensive heterogeneity associated with operating methods and in particular ways of overcoming problems with retraction and instrumentation. Published complications, morbidity, and hospital length of stay are comparable to conventional laparoscopy. Although SILS provides excellent cosmetic results and morbidity seems similar to conventional laparoscopy, larger randomized controlled trials are needed to assess the safety and efficacy of this novel technique.

Treatment of stress fracture of the olecranon in throwing athletes with internal fixation through a small incision

PubMed Central

2012-01-01

The present study is a report of retrospective case series of stress fracture of the olecranon. Six patients presented posterior elbow pain in throwing in baseball and softball, but fracture was not diagnosed in radiographs. We detected stress fracture of the olecranon using computed tomographic (CT) scan and treated the patient with internal fixation with a headless cannulated double threaded screw through a small skin incision. All patients returned to competitive level without elbow complaints after the operation. When throwing athletes present with unusual posterior elbow pain and no significant findings on radiographs, a CT scan examination should be performed. We recommend surgical treatment of internal fixation with a screw through a small skin incision, as a good option for stress fracture of the olecranon in order to allow early return to sports activity in competitive athletes.

Although ultrasound is an essential investigative modality in obstetrics and gynecology, the potential for therapeutic high-intensity focused ultrasound (HIFU) (also referred to as focused ultrasound surgery, FUS) to offer an alternative to invasive surgery is less well known. The ability of HIFU to create discrete regions of tissue necrosis only in precisely targeted positions by careful placement of the focus, without the need for any surgical intervention, has made HIFU of interest to those seeking noninvasive alternatives to conventional abdominal surgery. This article reviews the current experimental and clinical experience with HIFU in obstetrics and gynecology, and outlines potential future applications in fetal medicine and the challenges faced in their development. © Georg Thieme Verlag KG Stuttgart · New York.

Acute abdomen is a rare entity in the pregnant patient, with an incidence of one in 500-635 patients. Its appearance requires a quick response and an early diagnosis to treat the underlying disease and prevent maternal and fetal morbidity. Imaging tests are essential, due to clinical and laboratory masking in this subgroup. Appendicitis and complicated biliary pathology are the most frequent causes of non-obstetric acute abdomen in the pregnant patient. The decision to operate, the timing, and the surgical approach are essential for a correct management of this pathology. The aim of this paper is to perform a review and update on the diagnosis and treatment of non-obstetric acute abdomen in pregnancy. Copyright © 2015 AEC. Publicado por Elsevier España, S.L.U.

Results of prospective randomized comparative research of 2 total hemoglobin estimation methods are presented. There were laboratory tests and continuous noninvasive technique with multiwave spectrophotometry on the Masimo Rainbow SET. Research was carried out in two stages. At the 1st stage (gynecology)--67 patients were included and in second stage (obstetrics)--44 patients during and after Cesarean section. The standard deviation of noninvasive total hemoglobin estimation from absolute values (invasive) was 7.2 and 4.1%, an standard deviation in a sample--5.2 and 2.7 % in gynecologic operations and surgical delivery respectively, that confirms lack of reliable indicators differences. The method of continuous noninvasive total hemoglobin estimation with multiwave spectrophotometry on the Masimo Rainbow SET technology can be recommended for use in obstetrics and gynecology.

To describe a surgical technique for, and outcome after, laparoscopic vasectomy of free-ranging elephants. Case series. African elephants (Loxodonta africana; n = 14). Male elephants (12-35 years old) were anesthetized with etorphine and supported in a sling in a modified standing position, and positive pressure ventilated with oxygen. Anesthesia was maintained with IV etorphine. Vasectomy was performed under field conditions by bilateral, open-approach, flank laparoscopy with the abdomen insufflated with filtered ambient air. A 4-cm segment of each ductus deferens was excised. Behavior and incision healing were recorded for 8 months postoperatively. Successful bilateral vasectomy (surgical time, 57-125 minutes) was confirmed by histologic examination of excised tissue. Recovery was uneventful without signs of abnormal behavior. Large intestine lacerations (3 elephants; 1 full and 2 partial thickness) were sutured extracorporeally. One elephant found dead at 6 weeks, had no prior abnormal signs. Skin incisions healed without complication. Laparoscopic vasectomy can be performed in African elephants in their natural environment. © Copyright 2014 by The American College of Veterinary Surgeons.

Background Nipple-sparing mastectomy (NSM), understood as an oncologically valid procedure, is relatively new, and is an evolution of traditional mastectomy, particularly in relation to breast-conserving surgery. The anterior perforating branches are responsible for the cutaneous vascularization of the breast skin, and their preservation is a fundamental step to avoid possible postoperative necrosis. Therefore, evaluating the potential complications of cancer-related reconstructive surgical procedures such as NSM, both the distance of the tumoral lesion from the skin and the surgical incision site should be carefully considered. The preferred site of incision corresponds to the inframammary fold or possibly the periareolar area. Methods We retrospectively reviewed 113 patients who underwent NSM from January 2005 to October 2012 to evaluate skin complications. The anatomical study was performed by magnetic resonance imaging of the breast. Results Only one of the 113 women who had undergone a NSM procedure had total necrosis (0.9%) and six patients had partial necrosis (5.8%) of the nipple-areola complex. PMID:26203275

Six free-ranging marine otters (Lontra felina) were livetrapped on the central coast of Chile and implanted with specially designed radiotransmitters as part of a spatial ecology study. Marine otters frequent the rocky seashore, often squeezing their narrow bodies through cracks and crevices and grooming themselves on the rocks. They are also among the smallest of the otter species, weighing between 3.4 kg and 4.5 kg. For these reasons, the transmitter used was small, rectangular, and flat, measuring 3.5 x 3.2 x 1.0 cm. They were implanted using a ventral midline approach to minimize contact between the skin incision and sharp-edged rocks. Surgical incisions healed within 2 wk. The transmitters functioned well, but the duration varied from 62 days to 143 days instead of the 240 days predicted by the manufacturer. All six marine otters reestablished in their home ranges, and survey results suggest they survived well beyond the life of the transmitters.

Objective To estimate the total annual societal cost of uterine fibroids in the United States, based on direct and indirect costs, including associated obstetric complications. Study Design A systematic review of the literature was conducted to estimate the number of women seeking treatment for symptomatic fibroids annually, the costs of medical and surgical treatment, work lost and obstetric complications attributable to fibroids. Total annual costs were converted to 2010 U.S. dollars. A sensitivity analysis was performed. Results The estimated annual direct costs (surgery, hospital admissions, outpatient visits, medications) were $4.1 to $9.4 billion. Estimated lost work costs ranged from $1.55 to $17.2 billion annually. Obstetric outcomes attributed to fibroids resulted in a cost of $238 million to $7.76 billion annually. Uterine fibroids were estimated to cost the US $5.9 to $34.4 billion annually. Conclusions Obstetric complications associated with fibroids contributed significantly to their economic burden. Lost work costs may account for the largest proportion of societal costs due to fibroids. PMID:22244472

Gynecomastia describes a benign increase of the mammary gland in men. When medical treatment fails, symptoms and psychological alterations persist. Subdermal mastectomy is the definitive treatment and can be achieved by different incisions, each with potential complications. We undertook this study to present clinical characteristics of 11 patients with gynecomastia and the results obtained with subdermal mastectomy by means of external periareolar incision. A descriptive cohort study in male patients with gynecomastia was carried out in a third-level medical care hospital. Patients were treated with subdermal mastectomy by means of external periareolar incision. There were 11 male patients with an average age of 19 years (range: 11-60 years), 3 patients (27.2%) with bilateral gynecomastia and 8 patients (72.7%) with unilateral gynecomastia. Average time of evolution was 22 months (range: 16-48 months), 9 patients (81.8%) reported pain, 11 patients (100%) reported psychological alterations with cutaneous alteration, 11 patients (100%) had normal secondary sexual characteristics, 1 patient (9%) had supernumerary nipple development, and 11 patients (100%) had well-defined lesions. According to Simon's classification: seven patients (63.6%) were classified as grade 1, three patients (27.2%) as grade 2 and one patient (9.09%) as grade 3. Each patient had a subdermal mastectomy with external periareolar incision, 11 patients (100%) had a histopathological report of gynecomastia; 1 patient (9.09%) displayed keloid healing and none displayed complications inherent to the surgical procedure. Mastectomy by means of external periareolar incision is useful in the treatment of gynecomastia.

Use of electronic transmitter and monitoring systems to track movements of aquatic animals has increased continuously since the inception of these systems in the mid-1950s. The purpose of the present report is to provide information about veterinary principles and their incorporation into surgical implantation procedures for fish. We also intend to provide insight into the unique challenges of field-based aquatic surgical studies. Within this context, 4 aspects of the process for surgical implantation of transmitters in fish (ie, handling, aseptic technique, anesthesia, and implantation) will be described. Effects of surgical insertion of transmitters (ie, tagging) and aspects of the surgical implantation process where collaboration and professional exchanges among nonveterinarian researchers and veterinarians may be most fruitful will be discussed. Although this report focuses on surgical implantation, the principles and protocols described here (other than incision and suture placement) are also applicable to studies that involve injection of transmitters into fish.

A primer on standards setting as it applies to surgical education and credentialing.

Surgical technological advances in the past three decades have led to dramatic reductions in the morbidity associated with abdominal procedures and permanently altered the surgical practice landscape. Significant changes continue apace including surgical robotics, natural orifice-based surgery, and single-incision approaches. These disruptive technologies have on occasion been injurious to patients, and high-stakes assessment before adoption of new technologies would be reasonable. We reviewed the drivers for well-established psychometric techniques available for the standards-setting process. We present a series of examples that are relevant in the surgical domain including standards setting for knowledge and skills assessments. Defensible standards for knowledge and procedural skills will likely become part of surgical clinical practice. Understanding the methodology for determining standards should position the surgical community to assist in the process and lead within their clinical settings as standards are considered that may affect patient safety and physician credentialing.

Within only a few decades from its initial introduction, the field of surgical robotics has evolved into a dynamic and rapidly growing research area with increasing clinical uptake worldwide. Initially introduced for stereotaxic neurosurgery, surgical robots are now involved in an increasing number of procedures, demonstrating their practical clinical potential while propelling further advances in surgical innovations. Emerging platforms are also able to perform complex interventions through only a single-entry incision, and navigate through natural anatomical pathways in a tethered or wireless fashion. New devices facilitate superhuman dexterity and enable the performance of surgical steps that are otherwise impossible. They also allow seamless integration of microimaging techniques at the cellular level, significantly expanding the capabilities of surgeons. This paper provides an overview of the significant achievements in surgical robotics and identifies the current trends and future research directions of the field in making surgical robots safer, smaller, and smarter.

The purpose of this paper is to examine whether the current surgical reimbursement system in Japan reflects resource utilization after the revision of fee schedule in 2014. The authors collected data from all the surgical procedures performed at Teikyo University Hospital from April 1 through September 30, 2014. The authors defined the decision-making unit as a surgeon with the highest academic rank in the surgery. Inputs were defined as the number of medical doctors who assisted surgery, and the time of operation from skin incision to closure. An output was defined as the surgical fee. The authors calculated surgeons' efficiency scores using data envelopment analysis. The efficiency scores of each surgical specialty were significantly different (p=0.000). This result demonstrates that the Japanese surgical reimbursement scales still fail to reflect resource utilization despite the revision of surgical fee schedule.

2016-07-01

This study aimed to describe the incidence and risk factors of in-hospital spinal hematoma and abscess associated with epidural analgesia in adult obstetric and non-obstetric populations in the United States. The Nationwide Inpatient Sample was analyzed to identify patients receiving epidural analgesia from 1998 to 2010. Primary outcomes were incidence of spinal hematoma and epidural abscess. Use of decompressive laminectomy was also investigated. Regression analyses were conducted to assess predictors of epidural analgesia complications. Differences in mortality and disposition of patients at discharge were compared in patients with and without neuraxial complications. Obstetric and non-obstetric patients were studied separately. A total of 3,703,755 epidural analgesia procedures (2,320,950 obstetric and 1,382,805 non-obstetric) were identified. In obstetric patients, the incidence of spinal hematoma was 0.6 per 100,000 epidural catheterizations (95% CI, 0.3 to 1.0 × 10(-5) ). The incidence of epidural abscess was zero. In non-obstetric patients, the incidence of spinal hematoma and epidural abscess were, respectively, 18.5 per 100,000 (95% CI, 16.3 to 20.9 × 10(-5) ) and 7.2 per 100,000 (95% CI, 5.8 to 8.7 × 10(-5) ) catheterizations. Predictors of spinal hematoma included type of surgical procedure (higher in vascular surgery), teaching status of hospital, and comorbidity score. Patients with spinal complications had higher in-hospital mortality (12.2% vs. 1.1%, P < 0.0001) and were significantly less likely to be discharged to home. This large nationwide data analysis reveals that the incidence of epidural analgesia-related complications is very low in obstetric population epidural analgesia and much higher in patients having vascular surgery. © 2016 The Acta Anaesthesiologica Scandinavica Foundation.

2013-02-01

The present paper describes the rationale behind the surgical technique and the clinical results of the iso-anatomical, single bundle bone patellar-tendon bone anterior cruciate ligament (ACL) reconstruction. Using a second incision on the distal lateral femur an outside-in femoral tunnel is drilled. Guided by a special aiming device it is possible to place the femoral tunnel in the centre of the ACL footprint in every single case. Since every crucial step of the procedure is under visual control, the technique is safe and reliable, which is mirrored by good clinical results.

A survey of obstetric and gynaecology trainees in Australia found the trainee's opinion of the consultants' teaching ability for laparoscopic procedures and procedures dealing with complications as 'poor' in 21.2% and 23.4% of responses, respectively (Aust NZ J Obstet Gynaecol 2009; 49: 84). Surgical caseload per trainee is falling for a variety of reasons. Strategies need to be adopted to enhance the surgical learning experience of trainees in the operating room. We describe the use of a structured encounter template to facilitate the teaching of surgery in the operating room and report the response of the trainees to this intervention. Trainees attached to a gynaecologic surgery unit all underwent surgical training using a set format based on the surgical encounter template, including briefing, goal setting and intra-operative teaching aims as well as debriefing. Data on the trainees' experience and perception of their learning experience were then collected and analysed as quantitative and qualitative data sets. The trainees reported satisfaction with the use of a structured encounter template to facilitate the surgical teaching in the operating room. Some trainees had not received such clarity of feedback or the opportunity to complete a procedure independently prior to using the structured encounter template. A structured surgical encounter template based on andragogy principles to focus consultant teaching in the operating room is highly acceptable to obstetric and gynaecology trainees in Australia. Allowing the trainee the opportunity to set objectives and receive feedback empowers the trainee and enhances their educational experience. © 2015 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Robotics and general surgery.

PubMed

Jacob, Brian P; Gagner, Michel

2003-12-01

Robotics are now being used in all surgical fields, including general surgery. By increasing intra-abdominal articulations while operating through small incisions, robotics are increasingly being used for a large number of visceral and solid organ operations, including those for the gallbladder, esophagus, stomach, intestines, colon, and rectum, as well as for the endocrine organs. Robotics and general surgery are blending for the first time in history and as a specialty field should continue to grow for many years to come. We continuously demand solutions to questions and limitations that are experienced in our daily work. Laparoscopy is laden with limitations such as fixed axis points at the trocar insertion sites, two-dimensional video monitors, limited dexterity at the instrument tips, lack of haptic sensation, and in some cases poor ergonomics. The creation of a surgical robot system with 3D visual capacity seems to deal with most of these limitations. Although some in the surgical community continue to test the feasibility of these surgical robots and to question the necessity of such an expensive venture, others are already postulating how to improve the next generation of telemanipulators, and in so doing are looking beyond today's horizon to find simpler solutions. As the robotic era enters the world of the general surgeon, more and more complex procedures will be able to be approached through small incisions. As technology catches up with our imaginations, robotic instruments (as opposed to robots) and 3D monitoring will become routine and continue to improve patient care by providing surgeons with the most precise, least traumatic ways of treating surgical disease.

Surgical anatomy is taught early in medical school training. The literature shows that many physicians, especially surgical specialists, think that anatomical knowledge of medical students is inadequate and nesting of anatomical sciences later in the clinical curriculum may be necessary. Quantitative data concerning this perception of an anatomical knowledge deficit are lacking, as are specifics as to what content should be reinforced. This study identifies baseline areas of strength and weakness in the surgical anatomy knowledge of medical students entering surgical rotations. Third-year medical students completed a 20-25-question test at the beginning of the General Surgery and Obstetrics and Gynecology rotations. Knowledge of inguinal anatomy (45.3%), orientation in abdominal cavity (38.8%), colon (27.7%), and esophageal varices (12.8%) was poor. The numbers in parentheses are the percentage of questions answered correctly per topic. In comparing those scores to matched test items from this cohort as first-year students in the anatomy course, the drop in retention overall was very significant (P = 0.009) from 86.9 to 51.5%. Students also scored lower in questions relating to pelvic organs (46.7%), urogenital development (54.0%), pulmonary development (17.8%), and pregnancy (17.8%). These data showed that indeed, knowledge of surgical anatomy is poor for medical students entering surgical clerkships. These data collected will be utilized to create interactive learning modules, aimed at improving clinically relevant anatomical knowledge retention. These modules, which will be available to students during their inpatient surgical rotations, connect basic anatomy principles to clinical cases, with the ultimate goal of closing the anatomical knowledge gap. © 2014 American Association of Anatomists.

Obstetric fistula is a debilitating childbirth injury that has been associated with high rates of psychological distress. Global efforts have helped to link women to surgical repair, but thus far no evidence-based interventions exist to address the psychological needs of these women during the hospital stay. In this paper, we describe the development of a psychological intervention for women in Tanzania who are receiving surgical care for an obstetric fistula. The intervention was developed based on theories of cognitive behavioral therapy and coping models. Content and delivery were informed by qualitative data collection with a range of stakeholders including women with fistula, and input from a study advisory board. The resulting intervention was six individual sessions, delivered by a trained community health nurse. The session topics were: 1) recounting the fistula story; 2) creating a new story about the fistula; 3) loss, grief and shame; 4) specific strategies for coping; 5) social relationships; and 6) planning for the future. A trial run of the intervention revealed that the intervention could be delivered with fidelity and was acceptable to patients. A future randomized control trial will evaluate the efficacy of this intervention to address the mental health symptoms of this population. PMID:25710896

[Consequences of increasing and ageing population of Basse-Normandie on gynecology and obstetrics activity].

In Basse-Normandie, the population over 65 years old will expend more rapidly between 2007 and 2042 (+11.6%) than the rest of the French population (+9.2%). The same population of Basse-Normandie will get old in the 15 years to come. The impact of these demographic changes over the activity in the gynecology-obstetrics field is not clearly identified. Although we cannot predict the technical and scientific developments in the next 15 years, we are presenting a model allowing to hypothesize about changes of gynecology and obstetrics according to population's aging. We have established a projection model for the realizable surgical acts in obstetrics and gynecology in accordance with the aging of the population in Basse-Normandie. The study was realized based on the acts concerning the cesarean sections (C-section), tubal sterilization, hysteroscopy and hysterectomy as well as ovarectomy and breast surgery. For each activity branch, the codes of the Classification commune des actes médicaux (CCAM) were selected and then removed from the Programme médicalisé des systèmes d'information (PMSI) database. We have used and adapted the Omphale model of the National Statistics and Economical Studies Institute and we have applied it for the period of 2009-2025. Our projection model has permeated to show a 5.5% regression of the C-section acts, a 2% incretion of the hysterectomies and hysteroscopies, 7.7% of ovarectomies as well as a 9.8% augmentation of the breast surgeries. However, we predict a 11.8% diminution of the sterilizations by tubal implants. Globally, the activity in obstetrics and gynecology will remain constant with an insignificant augmentation of 46 acts (0.01%). In Basse-Normandie, the surgical activity in gynecology-obstetrics will moderately increase in the next 15 years. This constant activity signifies that there is no need to form more residents than the number of practitioner to retire. The interest of this model is that it is applicable at a national level and it permits to confront the demographic data and the projections of different activities.

Introduction: Data on specific characteristics based on the gender of the unborn baby and their significance for obstetrics are limited. The aim of this study is to analyse selected parameters of obstetric relevance in the phases pregnancy, birth and postpartum period in dependence on the gender of the foetus. Materials and Methods: The selected study method comprised a retrospective data acquisition and evaluation from the Austrian birth register of the Department of Clinical Epidemiology of Tyrolean State Hospitals. For the analysis all inpatient singleton deliveries in Austria during the period from 2008 to 2013 were taken into account (live and stillbirths n = 444 685). The gender of the baby was correlated with previously defined, obstetrically relevant parameters. Results: In proportions, significantly more premature births and sub partu medical interventions (vaginal and abdominal surgical deliveries. episiotomies) were observed for male foetuses (p < 0.001). The neonatal outcome (5-min Apgar score, umbilical pH value less than 7.1, transfer to a neonatal special unit) is significantly poorer for boys (p < 0.001). Discussion: In view of the vulnerability of male foetuses and infants, further research is needed in order to be able to react appropriately to the differing gender-specific requirements in obstetrics.

There is a significant burden of disease in low-income countries that can benefit from surgical intervention. The goal of this survey was to evaluate the current ability of the Liberian health care system to provide safe surgical care and to identify unmet needs in regard to trained personnel, equipment, infrastructure, and outcomes measurement. A comprehensive survey tool was developed to assess physical infrastructure of operative facilities, education and training for surgical and anesthesia providers, equipment and medications, and the capacity of the surgical system to collect and evaluate surgical outcomes at district-level hospitals in Africa. This tool was implemented in a sampling of 11 county hospitals in Liberia (January 2011). Data were obtained from the Ministry of Health and by direct government-affiliated hospital site visits. The total catchment area of the 11 hospitals surveyed was 2,313,429--equivalent to roughly 67 % of the population of Liberia (3,476,608). There were 13 major operating rooms and 34 (1.5 per 100,000 population) physicians delivering surgical, obstetric, or anesthesia care including 2 (0.1 per 100,000 population) who had completed formal postgraduate training programs in these specialty areas. The total number of surgical cases for 2010 was 7,654, with approximately 43 % of them being elective procedures. Among the facilities that tracked outcomes in 2010, a total of 11 intraoperative deaths (145 per 100,000 operative cases) were recorded for 2009. The 30-day postoperative mortality at hospitals providing data was 44 (1,359 per 100,000 operative cases). Metrics were also used to evaluate surgical output, safety of anesthesia, and the burden of obstetric disease. A significant volume of surgical care is being delivered at county hospitals throughout Liberia. The density and quality of appropriately trained personnel and infrastructure remain critically low. There is strong evidence for continued development of emergency and essential surgical services, as well as improved surgical outcomes tracking, at county hospitals in Liberia. These results serve to inform the international community and donors of the ongoing global surgical and anesthesia crisis.

We report on our experience of repair of congenital duodenal obstruction using a circumumbilical incision. The aim of this report is to describe how a Bianchi approach provides a safe and invisible alternative to transverse abdominal incision for the repair of duodenal atresia. Between January 2005 and December 2009, we treated 13 cases with congenital duodenal obstruction using a circumumbilical incision (Group I) and 14 cases with this condition repaired using a standard transverse right upper abdominal incision (Group II). Surgical procedures included a diamond-shaped duodenoduodenostomy as originally described by Kimura and standard duodenal web excision. The circumumbilical incision utilized at our institution is a classic Bianchi procedure. The 2 groups were compared with regard to patient demographics, operative reports and postoperative outcomes. There were no differences in preoperative parameters such as gestational age, age at surgery, or body weight at operation between the 2 groups. The circumumbilical cohort and transverse incision cohort had similar rates of congenital anomalies (61.54% vs. 64.29%), Kimura diamond-shaped anastomosis (61.54% vs. 64.29%) with only a slight female predominance in Group I. The mean operating time in Group I was 65.0 min while mean duration of the operation in Group II was 64.64 min. The difference between groups was statistically not significant (p>0.05). The mean time to full enteral feeding for patients with an umbilical incision was significantly shorter (p<0.0001) compared to patients with a standard incision (6.92 days vs. 11.86 days). Mean postoperative hospital stay was longer for patients in Group II (19.71 days vs. 12.38 days; p<0.0001). The postoperative course was uneventful for all patients. There were no intra- or postoperative complications. We report on a first series comparing umbilical and transverse right upper abdominal incision for the treatment of congenital duodenal obstruction. Our results suggest that an umbilical incision offers all the benefits of a minimal access approach, including earlier feeding and shorter times to discharge. We consider our approach an intermediate step, with laparoscopy likely to become the "gold standard" for the treatment of congenital duodenal obstruction. © Georg Thieme Verlag KG Stuttgart · New York.

We compared changes in morphology and intraocular pressure (IOP) induced by clear 2.2-mm and 3.0-mm corneal incisions in a cohort of patients with cataracts. In 160 eyes (from 70 men and 90 women at the Ophthalmic Center of Sun Yat-sen University), optical coherence tomography and tonometry were performed at 1, 5, and 24 hours after cataract surgery. The main outcome measures were IOP, postoperative changes in Descemet membrane detachment (DMD), healing of the surgical incision, and inflammation of the anterior chamber. Five hours after surgery, patients with 2.2-mm and 3.0-mm incisions had lower IOPs (P < 0.017) as measured by noncontact tonometry, but the difference was significant only among patients with grade V cataracts (2.2 mm, 12.6 ± 1.2 mm Hg; 3.0 mm, 14.5 ± 0.9 mm Hg, P < 0.05). The incidence of endothelial gap at 24 hours after surgery was significantly higher in the 2.2-mm (50%) versus 3.0-mm (11.1%) group of patients with grade V cataracts (P < 0.05). The incidence of DMD at 5 hours was also significantly higher in the 2.2-mm group (75%) than in the 3.0-mm group (22.2%) only among patients with this grade (P < 0.05). Incision width made no difference among patients with grade I-IV lens nuclei; but among those with grade V, 3.0-mm incisions had significantly less endothelial gaping, less DMD, and higher mean IOPs. For these patients, smaller incisions may not be optimal, and eyes may be especially vulnerable within 5 hours of surgery.

With the resection of pituitary lesions, the anterior pituitary gland often obstructs transsphenoidal access to the lesion. In such cases, a gland incision and/or partial gland resection may be required to obtain adequate exposure. We investigate this technique and determine the associated risk of post-operative hypopituitarism. All patients who underwent surgical resection of a pituitary adenoma or Rathke cleft cyst (RCC) between July 2007 and January 2013 were analyzed for pre- and post-operative hormone function. The cohort of patients with gland incision/resection were compared to a case-matched control cohort of pituitary surgery patients. Total hypophysectomy patients were excluded from outcome analysis. Of 372 operations over this period, an anterior pituitary gland incision or partial gland resection was performed in 79 cases (21.2 %). These include 53 gland incisions, 12 partial hemi-hypophysectomies and 14 resections of thinned/attenuated anterior gland. Diagnoses included 64 adenomas and 15 RCCs. New permanent hypopituitarism occurred in three patients (3.8 %), including permanent DI (3) and growth hormone deficiency (1). There was no significant difference in the rate of worsening gland dysfunction nor gain of function. Compared to a control cohort, there was a significantly lower incidence of transient DI (1.25 vs. 11.1 %, p = 0.009) but no significant difference in permanent DI (3.8 vs. 4.0 %) in the gland incision group. Selective gland incisions and gland resections were performed in over 20 % of our cases. This technique appears to minimize traction on compressed normal pituitary gland during removal of large lesions and facilitates better visualization and removal of cysts, microadenomas and macroadenomas.

To explore the reason, key diagnosic point and therapeutic method of the incisions fat colliquation or infections at early stage after operation of lumbar disc herniation. From July 2007 to May 2012, clinical data of 11 patients with incision fat liquefaction or early infection after lumbar discectomy were retrospectively analyzed. There were 5 males and 6 females with an average age of 43.1 years, and the mean time of incisions fat colliquation or infection was 5 days and a half after operation. The main clinical features included local wound pain aggravating, fervescence, fresh seepage in the wound, and blood inflammatory index increased, etc. The wound could heal at the first treatment stage or not was an evaluation standard of curative effect. All patients were followed up with an average period of 21 months. The wounds of 10 cases healed at the first stage without recurrence and complications. In 1 case infected by staphylococcus aureus, distal part of the wound present local red, swelling and with wave motion at 2 months after operation, staphylococcus aureus infection was confirmed after puncture and bacterial culture, and 1 thrum was found after local incision. The wound healed after change dressings for 1 week, without recurrence after followed up for 13 months. Preventing the risk factors before operation, minimizing invasive technique during operation reasonable antibiotics application for the lumbar operation reguiring placement objects, and correctly handling with wound after operation could prevent and reduce the incidence of incisions fat liquefaction or infection after operation of lumbar disc herniation. For incision fat liquefaction or infection, early diagnosis, debridement, VSD negative pressure irrigation and drainage, to choosing sensitive antibiotics according to the results of drug sensitivity, may contribute to wound early healing and decrease complication.

Why do niches develop in Caesarean uterine scars? Hypotheses on the aetiology of niche development

Caesarean section (CS) results in the occurrence of the phenomenon ‘niche’. A ‘niche’ describes the presence of a hypoechoic area within the myometrium of the lower uterine segment, reflecting a discontinuation of the myometrium at the site of a previous CS. Using gel or saline instillation sonohysterography, a niche is identified in the scar in more than half of the women who had had a CS, most with the uterus closed in one single layer, without closure of the peritoneum. An incompletely healed scar is a long-term complication of the CS and is associated with more gynaecological symptoms than is commonly acknowledged. Approximately 30% of women with a niche report spotting at 6–12 months after their CS. Other reported symptoms in women with a niche are dysmenorrhoea, chronic pelvic pain and dyspareunia. Given the association between a niche and gynaecological symptoms, obstetric complications and potentially with subfertility, it is important to elucidate the aetiology of niche development after CS in order to develop preventive strategies. Based on current published data and our observations during sonographic, hysteroscopic and laparoscopic evaluations of niches we postulate some hypotheses on niche development. Possible factors that could play a role in niche development include a very low incision through cervical tissue, inadequate suturing technique during closure of the uterine scar, surgical interventions that increase adhesion formation or patient-related factors that impair wound healing or increase inflammation or adhesion formation.

Optical coherence tomography (OCT) has revolutionized imaging of ocular structures and various disease conditions. Though it has been used in the clinic for some decades, the OCT has only recently found its way into the operating theater. Early attempts at intraoperative OCT, hand-held and microscope mounted, have already improved our understanding of the surgical pathology and the role it might play in surgical decision-making. The microscope-integrated OCT now allows seamless, high-resolution, real-time imaging of surgical maneuvers from the incision to wound closure. Visualization of instruments and intraoperative tissue manipulation are possible with this in vivo modality and, therefore, help improve the outcome of surgery. In this article, we describe the advantages it offers during various vitreoretinal procedures.

Interest in humanitarian surgery is high among surgical and obstetric residents. The Colorado Humanitarian Surgical Skills Workshop is an annual 2-day course exposing senior residents to surgical techniques essential in low- and middle-income countries but not traditionally taught in US residencies. We evaluated the course's ability to foster resident comfort, knowledge, and competence in these skills. The cohort of course participants was studied prospectively. Participants attended didactic sessions followed by skills sessions using cadavers. Sample areas of focus included general surgery (mesh-free hernia repair), orthopedics (powerless external fixation), and neurosurgery (powerless craniotomy). Before and after the course, participants answered a questionnaire assessing confidence with taught skills; took a knowledge-based test composed of multiple choice and open-ended questions; and participated in a manual skills test of tibial external fixation. The Center for Surgical Innovation, University of Colorado School of Medicine. A total of 12 residents (11 general surgical and 1 obstetric) from ten US institutions. After the course, participants perceived increased confidence in performing all 27 taught procedures and ability to practice in low- and middle-income countries. In knowledge-based testing, 10 of 12 residents demonstrated improvement on multiple choice questioning and 9 of 12 residents demonstrated improvement on open-ended questioning with structured scoring. In manual skills testing, all external fixator constructs demonstrated objective improvement on structured scoring and subjective improvement on stability assessment. For senior residents interested in humanitarian surgery, a combination of skills-focused teaching and manual practice led to self-perceived and objective improvement in relevant surgical knowledge and skills. The Colorado Humanitarian Surgical Skills Workshop represents an effective model for transmitting essential surgical principles and techniques of value in low-resource settings.

Purpose To compare postoperative astigmatic correction between femtosecond lenticule extraction (FLEx) and small-incision lenticule extraction (SMILE) in eyes with myopic astigmatism. Methods We examined 26 eyes of 26 patients undergoing FLEx and 26 eyes of 26 patients undergoing SMILE to correct myopic astigmatism (manifest astigmatism of 1 diopter (D) or more). Visual acuity, cylindrical refraction, the predictability of the astigmatic correction, and the astigmatic vector components using Alpin’s method, were compared between the two groups 3 months postoperatively. Results We found no statistically significant difference in manifest cylindrical refraction (p=0.74) or in the percentage of eyes within ± 0.50 D of their refraction (p=0.47) after the two surgical procedures. Moreover, no statistically significant difference was detected between the groups in astigmatic vector components, namely, surgically induced astigmatism (0.80), target induced astigmatism (p=0.87), astigmatic correction index (p=0.77), angle of error (p=0.24), difference vector (p=0.76), index of success (p=0.91), flattening effect (p=0.79), and flattening index (p=0.84). Conclusions Both FLEx and SMILE procedures are essentially equivalent in correcting myopic astigmatism using vector analysis, suggesting that the lifting or non-lifting of the flap does not significantly affect astigmatic outcomes after these surgical procedures.

Periodontal surgery associated with prior waxing, mock-up, and the use of digital tools to design the smile is the current trend of reverse planning in periodontal plastic surgery. The objective of this study is to report a surgical resolution of the gummy smile using a prior esthetic design with the use of digital tools. A digital smile design and mock-up were used for performing gingival recontouring surgery. The relationship between the facial and dental measures and the incisal plane with the horizontal facial plane of reference were evaluated. The relative dental height x width was measured, and the dental contour drawing was inserted. Complementary lines are drawn such as the gingival zenith, joining lines of the gingival and incisal battlements. The periodontal esthetic was improved according to the established design digital smile pattern. These results demonstrate the importance of surgical techniques and are well accepted by patients and are easy to perform for the professional. When properly planned, they provide the desired expectations. Periodontal Surgical procedures associated with the design digital smile facilitate the communication between the patient and the professional. It is, therefore, essential to demonstrate the reverse planning of the smile and periodontal parameters with approval by the patient to solve the esthetic problem.

In a retrospective study, the authors analyzed the surgical approach to the intrathoracic goiter to avoid sternotomy or thoracotomy. We selected 70 intrathoracic cases of multinodular goiter out of 988 cases of thyroidectomy and compared them with cervical goiter cases. Surgical technique, results, and postsurgical complications were assessed. The analyzed cases presented the retrosternal goiter (n = 53; 75.7%), the retrotracheal goiter (n = 9; 12.8%), and the retroesophageal goiter (n = 8; 11.4%). Complaining of chest pressure or discomfort was specific for intrathoracic cases (50%; 35 of 70). All goiters except one were removed via cervical incision. The surgeons used head reclination and isthmus dissection when removing sizable goiters. Mean weight of goiters was 180 g. The recurrent laryngeal nerve was more often temporarily damaged in intrathoracic cases in comparison with cervical cases (4.3% vs. 2.8%, P  = .04), but the difference in permanent injury was less significant ( P  = .09). The incidence of temporary hypoparathyroidism was significantly higher in intrathoracic cases ( P  = .01). In cases of multinodular goiter the goiters of various extensions can be successfully removed via the cervical incision in most of the cases even if they occupy the retrosternal, retrotracheal, or retroesophageal position. The transthoracic approaches and sternotomy might be justified in malignant cases. 4.

Objective  Rectus muscle reapproximation at cesarean delivery (CD) is performed frequently by some obstetricians; however, the effect on postoperative pain is unclear. To this end, we investigated whether rectus muscle reapproximation increases postoperative pain. Materials and Methods  This is a prospective, double-blind, randomized controlled trial of women undergoing primary CD with singleton or twin pregnancy at >35 weeks' gestation. Women were randomized to rectus muscle reapproximation with three interrupted sutures or no reapproximation. Exclusion criteria were prior cesarean, prior laparotomy, vertical skin incision, active labor, chronic analgesia use, allergy to opioid or nonsteroidal anti-inflammatory drugs, and body mass index ≥ 40. Intra- and postoperative pain management was standardized within the study protocol. The primary outcome was a combined movement pain and opioid use score averaged over the 72-hour study period, called the Silverman integrated assessment. Movement pain scores were assessed at 24, 48, and 72 postoperative hours. Results  In total, 63 women were randomized, of whom 35 underwent rectus muscle reapproximation and 28 did not. Demographic and obstetric variables were similar between groups. Silverman integrated assessment scores during the 72-hour postoperative period were higher in the rectus muscle reapproximation group (15 ± 100% vs. –31 ± 78% difference from the mean; p  = 0.04). Operative times were similar between groups (63 ± 15 vs. 65 ± 15 minutes; p  = 0.61), and there were no surgical complications in either group. Maternal satisfaction with analgesia at 72 hours was high in both groups (85% [73–90] rectus muscle reapproximation vs. 90% [75–100]; p  = 0.16). Conclusion  Rectus muscle reapproximation increased immediate postoperative pain without differences in operative time, surgical complications, or maternal satisfaction. Benefits of rectus muscle reapproximation should be weighed against increased postoperative pain, and analgesia should be planned accordingly. PMID:28840194

Minimizing Sources of Airborne, Aerosolized, and Contact Contaminants in the OR Environment.

Armellino, Donna

Surgical site infections are unintended consequences of surgery that can cause harm to patients and place financial burdens on health care organizations. Extrinsic factors in the OR-including health care providers' behavior and practices that modify air movement, the physical environment, equipment, or surgical instruments-can increase microbial contamination. Microbes can be transported into the surgical incision by airborne or contact routes and contribute to a surgical site infection. Simple practices to prevent infection-such as minimizing airborne particles and contaminants, maintaining equipment according to the manufacturer's recommendations, cleaning and disinfecting the environment and surgical instruments, and performing proper hand hygiene-can reduce the degree of microbial contamination. Perioperative leaders and health care providers can help decrease the patient's risk of surgical site infection with proactive preventive practices that break the chain of infection.

Objective: We developed a new surgical model of penile girth enhancement in dog, with minimal damage, fewer complications, and high success rate, to enable the experimental investigation of penile implants. Methods: We obtained materials for penile girth enhancement by processing the pericardium and blood vessel wall collected from pigs. Incisions were made at the penile bulb for the implantation of the materials, and facilitate observation and data collection, based on the anatomical features of dog’s penis. We measured the girth of the flaccid penis before and after the operation, and erectile function at 1-month postoperation. In addition to evaluation of recovery from the incision and local pathological changes, ultrasonic examination was performed to monitor the long-term changes associated with implantation. Results: The mean girth of the flaccid penis significantly increased from 7.37±0.40 cm before the operation, to 8.70±0.56 cm postoperation. Dogs resumed normal mating at 1 month after the operation, without any significant change in the mating time. Ultrasonic examination clearly illustrated the implants, and helped in the measurement of the distance between the materials and the baculum. Conclusion: Chinese Rural dog is a promising animal model for penile girth enhancement surgery. The findings demonstrated that surgical implantation into penile bulb was associated with less damage, faster postoperative recovery, and higher success. For the first time, ultrasonic examination provided objective data on the surgical outcomes of penile girth enhancement. PMID:26379868

Both surgical excision and radioiodine ablation are effective modalities in the management of hyperfunctioning thyroid nodules. Minimally invasive thyroid surgery (MITS) using the lateral mini-incision approach has previously been demonstrated to be a safe and effective technique for thyroid lobectomy. As such MITS may offer advantages as a surgical approach to hyperfunctioning thyroid nodules without the need for a long cervical incision or extensive dissection associated with formal open hemithyroidectomy. The aim of the present study was to assess the safety and efficacy of MITS for the treatment of hyperfunctioning thyroid nodules. This is a retrospective case study. Data were obtained from the University of Sydney Endocrine Surgical Unit Database from 2002 to 2007. There were 86 cases of hyperfunctioning thyroid nodules surgically removed during the study period, of which 10 (12%) were managed using the MITS approach. The ipsilateral recurrent laryngeal nerve was identified and preserved in all cases with no incidence of temporary or permanent nerve palsy. The external branch of the superior laryngeal nerve was visualized and preserved in eight cases (80%). There were no cases of postoperative bleeding. There was one clinically significant follicular thyroid carcinoma in the series (10%). In nine of 10 cases (90%) normalization of thyroid function followed surgery. MITS is a safe and effective procedure, achieving the benefits of a minimally invasive procedure with minimal morbidity. As such it now presents an attractive alternative to radioiodine ablation for the management of small hyperfunctioning thyroid nodules.

Vaginal-sparing ventral buccal mucosal graft urethroplasty for female urethral stricture: A novel modification of surgical technique.

To present a novel modification of surgical technique to treat female urethral stricture (FUS) by a vaginal-sparing ventral buccal mucosal urethroplasty. Recurrent FUS represents an uncommon, though difficult clinical scenario to manage definitively. A variety of surgical techniques have been described to date, yet a lack of consensus on the optimal procedure persists. We present a 51-year-old female with urethral stricture involving the entire urethra. Suspected etiology was iatrogenic from cystoscopy 17 years prior. Since then, the patient had undergone at least 25 formal urethral dilations and periods of self-dilation. In lithotomy position, the urethra was dilated to accommodate forceps, and ventral urethrotomy carried out sharply, exposing a bed of periurethral tissue. Buccal mucosa was harvested, and a ventral inlay technique facilitated by a nasal speculum, was used to place the graft from the proximal urethra/bladder neck to urethral meatus without a vaginal incision. Graft was sutured into place, and urethral Foley catheter inserted. The vaginal-sparing ventral buccal mucosal graft urethroplasty was deemed successful as of last follow-up. Flexible cystoscopy demonstrated patency of the repair at 6 months. At 10 months of follow-up, the patient was voiding well, with no urinary incontinence. No further interventions have been required. This case describes a novel modification of surgical technique for performing buccal mucosal urethroplasty for FUS. By avoiding incision of the vaginal mucosa, benefits may include reduced: morbidity, urinary incontinence, and wound complications including urethro-vaginal fistula.

Despite the low incidence of brain abscesses in Western nations (1-2%), the incidence in developing countries is as high as 8%. We evaluate a minimally invasive image-guided keyhole aspiration of cerebral abscesses and compare it with a series of cases treated with surgical excision. 23 patients (20 male and 3 female, aged 7-67 years) underwent image-guided burr hole aspiration of single or multiple cerebral abscesses. Patient characteristics, perioperative, and postoperative data were analyzed and compared with a second group of 22 patients (14 male and 8 female, aged 12-72) treated for cerebral abscesses with open surgical excision. In all cases, the surgical procedure was performed successfully without complication. 8 of the 23 aspiration cases were performed with the aid of iMRI. A comparison of patient demographics, duration of hospital stay, duration of antibiotic therapy, postoperative neurological recovery time, intraoperative blood loss, operative duration, length of incision, postoperative fever, repeat surgery, and mortality was performed between the aspiration and excision groups. Intraoperative blood loss, operative duration, length of incision, and postoperative fever were all significantly reduced in the aspiration group. Though, duration of hospital stay and antibiotic therapy and postoperative neurological recovery time were all increased in the aspiration group, and statistical significance was observed in all except the duration of hospital stay. This technique is a feasible and comparable minimally invasive alternative to open surgical excision and may provide reduced intraoperative blood loss, shortened operative duration, improved cosmetic outcomes, and a lessened incidence of postoperative fever.

Strategies to reduce blood product utilization in obstetric practice.

Patient blood management (PBM) aims to improve patient outcome and safety by reducing the number of unnecessary RBC transfusions and vitalizing patient-specific anemia reserves. Although PBM is increasingly recognized as best clinical practice in elective surgery, implementation of PBM is restrained in the setting of obstetrics. This review summarizes recent findings to reduce blood product utilization in obstetric practice. PBM-related evidence-based benefits should be urgently adopted in the field of obstetric medicine. Intravenous iron can be considered a safe, effective strategy to replenish iron stores and to correct both pregnancy-related and hemorrhage-related iron deficiency anemia. In addition to surgical techniques and the use of uterotonics, recent findings support early administration of tranexamic acid, fibrinogen and a coagulation factor concentrate-based, viscoelastically guided practice in case of peripartum hemorrhage to manage coagulopathy. In patients with cesarean section, autologous red cell blood salvage may reduce blood product utilization, although its use in this setting is controversial. Implementation of PBM in obstetric practice offers large potential to reduce blood loss and transfusion requirements of allogeneic blood products, even though large clinical trials are lacking in this specific field. Intravenous iron supplementation may be suggested to increase peripartum hemoglobin levels. Additionally, tranexamic acid and point-of-care-guided supplementation of coagulation factors are potent methods to reduce unnecessary blood loss and blood transfusions in obstetrics.

To evaluate the effect of cornea eccentricity on induced astigmatism after cataract surgery. The study included 125 eyes of 87 patients. Preoperative corneal astigmatism, pachymetry, and eccentricity were measured. During cataract surgery, the location of the main incision (2.8-mm clear corneal) was selected to be either superior, superior-nasal, superior-temporal, nasal, or temporal to decrease the preexisting corneal astigmatism. Aspheric intraocular lenses were implanted. Keratometry and manifest refraction were recorded 6 months after surgery. Astigmatism was calculated using vector subtraction software. Three parameters significantly affected postoperative astigmatism: preoperative amount of corneal astigmatism, eccentricity of anterior cornea, and location of the main incision. The mean surgically induced astigmatism (SIA) was calculated to be: superior = 0.82 diopters (D), superior-nasal = 0.50 D, superior-temporal = 0.63 D, temporal = 0.45 D, and nasal = 0.55 D. Superior incision induced the greatest SIA and temporal incision induced the smallest SIA. The eccentricity of anterior cornea showed significantly positive correlation with the amount of SIA (P < .001). The preoperative corneal cylinder power showed significantly positive correlation with the amount of SIA (P < .001). Postoperative astigmatism was affected by various factors in cataract surgery. The greatest postoperative astigmatism is expected in corneas with high anterior eccentricity, high preoperative corneal astigmatism, and superior location of the main incision.

ABSTRACT Objectives The purpose of the present study was to review the literature of how to identify the mental foramen, mandibular incisive canal and associated neurovascular bundles during implant surgery and how to detect and avoid the damage of these vital structures during implant therapy. Material and Methods Literature was selected through a search of PubMed, Embase and Cochrane electronic databases. The keywords used for search were mandibular incisive canal, mental foramen, mental nerve, anterior mental loop. The search was restricted to English language articles, published from 1979 to November 2009. Additionally, a manual search in the major anatomy, dental implant, and periodontal journals and books was performed. Results In total, 47 literature sources were obtained and reviewed. The morphology and variations of the mandibular incisive canal, mental foramen and associated neurovascular bundles were presented as two entities. It suggested that clinicians should carefully assess these vital structures to avoid nerve/artery damage. Conclusions The mandibular incisive canal, mental foramen and associated neurovascular bundles exist in different locations and possess many variations. Individual, gender, age, race, assessing technique used and degree of edentulous alveolar bone atrophy largely influence these variations. It suggests that the clinicians should carefully identify these anatomical landmarks, by analyzing all influencing factors, prior to their implant surgical operation. PMID:24421959

Robot-assisted Sistrunk's operation, total thyroidectomy, and neck dissection via a transaxillary and retroauricular (TARA) approach in papillary carcinoma arising in thyroglossal duct cyst and thyroid gland.

Carcinomas arising in the thyroglossal duct cysts are rare, accounting only for about 0.7-1.5 % of all thyroglossal duct cysts. Synchronous occurrence of thyroglossal duct carcinoma and thyroid carcinoma is reported to be even rarer. Traditionally, surgical treatments of such coexisting thyroglossal duct cyst carcinoma (TGDCa) and papillary thyroid carcinoma (PTC) were typically performed through a single transverse or double incisions on the overlying skin. A longer, extended cervical incision might be required if neck dissection is necessary. Though this method provides the operator with the optimal surgical view, the detrimental cosmetic effect on the patient of possessing a scar cannot be avoided, despite the effort of the surgeon to camouflage the scar by placing the incision in natural skin creases. Recently, the authors have previously reported the feasibility of robot-assisted neck dissections via a transaxillary and retroauricular ("TARA") approach or modified face-lift approach in early head and neck cancers. On the basis of the forementioned surgical technique, we demonstrate our novel technique for robot-assisted Sistrunk's operation via retroauricular approach as well as robot-assisted neck dissection with total thyroidectomy via transaxillary approach. This is a case presentation of a 22-year-old woman with synchronous TGDCa and PTC with minimal lymph node metastasis who underwent resection of TGDCa and total thyroidectomy with left neck level III and IV lymph node dissection as well as central compartment lymph node dissection (CCND) via TARA approach with a robotic surgery system after approval from the institutional review board at Severance Hospital, Yonsei University College of Medicine. The incision was just like the TARA approach in head and neck cancer, which has been reported by our institute. The operation was proceeded as follows. First, excision of the TGDCa through the retroauricular incision was done followed by total thyroidectomy with CCND via transaxillary approach. Finally, neck dissection of left level III, IV was conducted via transaxillary approach. The da Vinci surgical system (Intuitive Surgical, Sunnyvale, CA) was introduced via retroauricular or transaxillary port. A 30° dual-channel endoscope was used, and the two instrument arms were equipped with 5 mm Maryland forceps and a 5 mm spatula monopolar cautery for TGDCa excision via retroauricular approach. When conducting total thyroidectomy and neck dissection via transaxillary approach, three instrument arms were utilized, each equipped with 5 mm Maryland forceps, ProGrasp forceps and a 5 mm spatula monopolar cautery or Harmonic curved shears. The rest of the surgery was completed with the robotic system (see Video). The operative procedure was successfully completed utilizing the robotic surgical system with no conversion to open surgery. The operation time for TGDCa excision was 97 min, including the time for skin flap elevation (15 min), setting up the robotic system (5 min), and console time using the robotic system (77 min). Also, the total operation time for the consecutive total thyroidectomy with CCND and level III, IV dissection was 142 min including the time for skin flap elevation (27 min), setting up the robotic system (3 min), and console time using the robotic system (112 min). There were no intraoperative complications. The retroauricular approach for the removal of the TGDCa allowed for an excellent magnified surgical view revealing important structures of the local anatomy. It also created sufficient space for the cutting of the relevant portion of the hyoid bone. Handling of the robotic instruments through the incision was technically feasible and safe without any mutual collisions throughout the operation. The patient's postoperative parathyroid hormone (PTH) level was within normal range and functions of her both vocal cords were intact. The histopathologic results of the specimens revealed thyroglossal duct cyst with internal papillary carcinoma measuring 1.1 cm with infiltrative tumor margins and papillary microcarcinoma measuring 0.9 cm within the left thyroid lobe with extrathyroidal soft tissue extension. There was no evidence of tumor in the right lobe and the pyramidal lobe of the thyroid gland. As for the lymph nodes resected, 7 out of 9 paratracheal nodes and 2 out of 7 left level III, IV nodes revealed metastatic carcinomas. The patient was discharged on the 8th day after the operation with no complications. The patient was extremely satisfied with the cosmetic results. The patient has received high-dose radioiodine ablation (RAI) therapy and is currently doing well with no evidence of recurrence. Although there is still a great deal of controversy regarding the treatment of TGDCa, there is little debate that for the cases of synchronous TGDCa and PTC, total thyroidectomy in addition to the Sistrunk procedure must be performed. As for the patient in our case where left level IV lymph node metastasis was detected under preoperative ultrasonography (USG), if the usual method of surgical procedure was to be selected, double incisions or a single extended transverse incision must be adopted for the Sistrunk's operation and total thyroidectomy with lateral neck dissection. The conventional method to remove neck masses was to do so by placing an incision on the overlying skin. This 'open' approach to viewing the lesion has an advantage of providing the operator with the best surgical view, but the recognizable surgical scar that results from the surgery can be displeasing for patients. Therefore the surgeon can try to make a small incision and camouflage the scar by placing the incision in natural skin creases, yet the cosmetic results can still be displeasing for the patient due to its visibility and permanence. This can be an even greater problem if the patient is young and an active member of his/her society and if the lesion is benign or low-grade malignancy which can be simply dissected and excised. Therefore it is the surgeon's best interest to perform an operation successfully with a 'least obvious' or 'hidden' scar whenever possible. Accordingly, we have adopted a novel approach, the transaxillary and retroauricular approach, in view of our increasing surgical experience with various indications such as submandibular gland (SMG) resections and neck dissections in head and neck cancer or thyroid papillary carcinoma. Some investigators have demonstrated that robot-assisted neck dissections performed on patients with thyroid cancer and lateral neck node metastasis are feasible and safe. We conducted total thyroidectomy with bilateral CCND and level III and IV dissection using the same approach. Although the technical feasibility and safety of neck dissection or SMG resection via retroauricular approach has already been reported previously at our institute, Sistrunk's operation via retroauricular approach will be challenging. In spite of that, we were able to demonstrate successfully Sistrunk's operation including the hyoid bone resection through the retroauricular approach. There are however, certain areas of potential difficulties which must be considered with caution during the operation procedure. First, when removing the TGDCa through the retroauricular port, identification of the ipsilateral hyoid bone is primarily important and it is also crucial that dissection along the capsule must be done carefully so as not to rupture the tumor. It is essential that sufficient working space must be created for the comfortable movement of the robotic arms through the retroauricular port and in order to do so, sufficient skin flap elevation in both superior and inferior directions must be performed. It is necessary to elevate the superior skin flap up to the level of the inferior border of the mandible but during this process, the platysma muscle must be identified and meticulous dissection along the subplatysmal plane must be carried out so as not to damage the marginal mandibular branch of the facial nerve. Another area of potential pitfalls concerns the total thyroidectomy with neck dissection through the transaxillary port. Sufficient amount of working space must be secured in order to perform comfortably the contralateral thyroidectomy and neck dissection and in order to do so, skin flap elevation must be done at least 2 cm further based on the ipsilateral omohyoid muscle and the contralateral thyroid gland must be adequately exposed. Using the robotic surgical system in removing the thyroglossal duct cyst, the free movement of wristed instrumentation through the retroauricular incision allowed for efficient dissection and easy handling of the tissue. In this particular case we could not identify the tract beyond the hyoid and up to the foramen cecum, but we anticipate that there would be no technical problems of dissection and excision had it been so. To our knowledge, Sistrunk's operation and total thyroidectomy with lateral neck dissection via TARA approach utilizing the robotic surgical system has never been attempted before. It has some advantages over the conventional surgery in terms of cosmesis. However, careful consideration in selecting appropriate cases is required and prospective trials should be conducted to recognize long-term outcomes and to overcome potential limitations.

To compare the astigmatic correction in high myopic astigmatism between small-incision lenticule extraction and laser in situ keratomileusis (LASIK) using vector analysis. Hong Kong Laser Eye Center, Hong Kong. Retrospective case series. Patients who had correction of myopic astigmatism of 3.0 diopters (D) or more and had either small-incision lenticule extraction or femtosecond laser-assisted LASIK were included. Only the left eye was included for analysis. Visual and refractive results were presented and compared between groups. The study comprised 105 patients (40 eyes in the small-incision lenticule extraction group and 65 eyes in the femtosecond laser-assisted LASIK group.) The mean preoperative manifest cylinder was -3.42 D ± 0.55 (SD) in the small-incision lenticule extraction group and -3.47 ± 0.49 D in the LASIK group (P = .655). At 3 months, there was no significant between-group difference in uncorrected distance visual acuity (P = .915) and manifest spherical equivalent (P = .145). Ninety percent and 95.4% of eyes were within ± 0.5 D of the attempted cylindrical correction for the small-incision lenticule extraction and LASIK group, respectively (P = .423). Vector analysis showed comparable target-induced astigmatism (P = .709), surgically induced astigmatism vector (P = .449), difference vector (P = .335), and magnitude of error (P = .413) between groups. The absolute angle of error was 1.88 ± 2.25 degrees in the small-incision lenticule extraction group and 1.37 ± 1.58 degrees in the LASIK group (P = .217). Small-incision lenticule extraction offered astigmatic correction comparable to LASIK in eyes with high myopic astigmatism. Copyright © 2018 ASCRS and ESCRS. Published by Elsevier Inc.

The rhytidectomy approach for parotidectomy allows the incision to be hidden, and post-operative scarring minimised. Furthermore, separate elevation of the Superficial Musculo-Aponeurotic System (SMAS) reduces the incidence of Frey's syndrome, and provides vascularized soft tissue for contour reconstruction. The technique has gained popularity particularly with plastic surgeons, but concerns persist that with this approach, particularly with lesions located anteriorly, access to the gland may be inadequate, and facial nerve identification may be compromised. We undertook an anatomical study to quantitatively compare the surgical access achieved using the facelift approach with the conventional Blair incision, by comparing the distances between the parotid edge and the retracted flaps. Despite reduced tissue elasticity due to formaldehyde fixation, it proved possible to demonstrate all regions of the parotid gland to the operating surgeon with either approach. There were no significant differences in the distance between the parotid edge and the retracted skin flaps (P > 0.1; paired t-test). The facelift approach provides at least equal access to all regions of the parotid gland when compared to a Blair's incision. It is a superior approach aesthetically and its more widespread use in parotid surgery is advocated.

Vault haematoma is one of the most common complication of vaginal hysterectomy. The aim of this work was to analyse the effects of a modification of incision and closure technique of the vaginal vault on the incidence of vault haematoma after vaginal hysterectomy. The study group consisted of 333 women of whom 49 (group A) underwent vaginal hysterectomy traditional technique of incision and closure of the vaginal vault, an 284 (group B) modified technique. Following parameters were evaluated: number of vault haematomas, blood loss, postoperative fever, required antibiotics, length of hospital stay. The risk of vault haematoma was significantly lower in the group B (1,06% vs 12,4%). Loss of blood was higher in group A (310 ml vs 206 ml). Incidence of postoperative fever was in 12,2% patients from group A, and 1,4% from group B. The length of hospitalization was lower for women in group B (4,3 days compared with 7,3 days). The modification of incision and closure technique of the vaginal vault during vaginal hysterectomy is recommended to minimise intra- and postoperative complications.

The ideal surgical laser for the treatment of soft tissue pathology should possess both ablative and hemostatic abilities. As well, for use in urologic conditions the laser must also be suitable for endoscopic use. The Holmium:YAG laser possesses these qualities and in preliminary clinical use has demonstrated a variety of potential urologic applications. In this study we review our initial experience with the Holmium:YAG laser over a 18 month period. A total of 51 patients underwent 53 procedures for a variety of soft tissue conditions including: bladder tumor ablation (25), incision of ureteral stricture (15), incision of urethral stricture (6), treatment of ureteropelvic junction obstruction (3), incision of bladder neck contracture (2), and ablation of a ureteral tumor (2). Satisfactory hemostasis was achieved in all cases. Procedures were considered successful (no further intervention being required to treat the condition) in 81% of the cases. Two patients with dense bladder neck contractures required electroincision under the same anesthetic for completion of the procedure. A single complication, that of urinary extravasation following incision of a urethral stricture resolved with conservative management. In summary, the Holmium:YAG laser has demonstrated safety and proficiency in the treatment of a variety of urologic soft tissue conditions.

Open reduction through an intercartilaginous incision was useful for treating delayed-diagnosed nasal bone fractures because it resulted in a successful outcome with minimal complications. Nasal bone fractures are generally managed with closed reduction, which is usually inadequate and results in airway obstruction with a delayed diagnosis of nasal bone fracture when bone healing and fibrotic adhesions around the bone fragment have progressed. This study investigated the surgical outcome of open reduction through an intercartilaginous incision for delayed-diagnosis nasal bone fractures. The study enrolled 18 patients who underwent open reduction through an intercartilaginous incision to correct delayed-diagnosis nasal bone fractures. Three independent otorhinolaryngologists evaluated the outcomes 4-35 months (average 12.7 months) postoperatively as excellent, fair or poor. The time from injury to surgery was 11-39 days (20-39 days in adults and 11-30 days in children). The 18 cases included 16 primary repairs and two revisions. A Kirschner wire was inserted in six (33.3%) patients who had unstable reduced nasal bones. Postoperatively, l5 (83%) patients had excellent results, two (11%) had fair, and one (6%) had a poor outcome. No patient experienced any complication.

Currently available aortic stent-grafts require bilateral femoral incisions for device deployment. The incidence of morbidity (infection, lymphatic complications, breakdown) of vertical, infrainguinal incisions used in endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms (AAAs) was assessed, and the natural history of asymptomatic groin fluid collections following such procedures was determined. Between June 1999 and February 2001, 77 consecutive patients underwent EVAR for AAAs utilizing bilateral vertical femoral incisions. Fifty-nine (77%) bifurcated stent-grafts (BSGs), and 18 (23%) aortouniiliac (AUI) devices, with femorofemoral bypass were performed. Patients returned at 2 weeks, 1 month, and 6 months for physical examination, and 1 month and 6 months for abdominal and pelvic computed tomography (CT) scans. The presence of fluid collections was determined from the dictation report of the attending radiologist. Data are reported as (n) mean +/-SE. Patient characteristics were compared using Fisher's exact test; p<0.05 considered significant. There were 72 males and 5 females, age 75 +/-6.4 years and aneurysm size (77) 5.6 +/-0.8 cm. There were no cases of wound breakdown or lymph fistula. Wound infections occurred in 3/150 incisions (2%), 2/34 AUI incisions (6%), and 1/116 BSG incisions (0.86%). There was no statistical difference (p=0.13) between graft types (BSG vs AUI). All infections were diagnosed clinically before the 1-month CT scan, treated without operative intervention or hospitalization, and resolved. There was a significant decrease in the BSG group and overall in asymptomatic wound fluid collections from 1 to 6 months postoperatively. At 1 and 6 months, respectively, the BSG group had 17 (14.6%) and 3 (2.6%) fluid collections out of 116 incisions (p=0.003); the AUI group had 6 (17.6%) and 1 (2.9%) fluid collection(s) out of 34 incisions (p=0.13); and overall 23 (15.3%) and 4 (2.6%) out of 150 incisions (p=0.004). The present study demonstrates that bilateral vertical femoral incisions used in EVAR have a wound infection rate of 2.0%. Infections are usually detected and treated clinically and empirically without the need for hospitalization or surgery. Asymptomatic groin wound fluid collections resolve significantly within 6 months without intervention. Therefore, surgical femoral artery exposure adds little morbidity to the endovascular repair of abdominal aortic aneurysms.

The Arnold P. Gold Humanism and Excellence in Teaching Awards are given by medical students to residents. The aim of this study is to evaluate the distribution of this award based on residency specialty. The hypothesis is that surgical residents more commonly receive this award. This was a retrospective study from 2004 to 2013. All award recipients were obtained from the Arnold P. Gold Foundation website. The specialties of award recipients were tabulated. The number of award winners per thousand specialty residents was estimated using the Accreditation Council for Graduate Medical Education Data Resource Book, adjusting for the number of awarding schools and resident specialties. All statistics used an α = 0.05. There were 2489 awards given during the study period, with 52.6% in medical specialties and 47.4% in surgical specialties (p = 0.45). The specialties most commonly awarded were General Surgery (22.3%), Internal Medicine (20.9%), and Obstetrics/Gynecology (20.4%). Adjusting for the number of eligible residents, there were 59.9 awards/1000 Obstetrics/Gynecology residents, 43.1 awards/1000 General Surgery residents, and 20.2 awards/1000 Internal Medicine residents (p < 0.001). Controlling for the number of eligible residents, the Arnold P. Gold Humanism and Excellence in Teaching Awards are more commonly given to surgical specialty residents.

Perioperative hypothermia and incidence of surgical wound infection: a bibliographic study

PubMed Central

da Silva, Aline Batista; Peniche, Aparecida de Cassia Giani

2014-01-01

The purpose of this review article was to understand and analyze the scientific production related to the occurrence of perioperative hypothermia and the incidence of infection on the surgical site. For this purpose, a search was conducted in the databases LILACS, MEDLINE, PubMed, CINAHL and Cochrane, using the health science descriptors DECS, from 2004 to 2009. A total of 91 articles were found. After eliminating duplicate items and using selection criteria for inclusion, six manuscripts remained for analysis. The studies were classified as retrospective, prospective, case studies, and clinical trials. After analysis, the majority of studies showed that hypothermia must be prevented during the perioperative period to reduce complications in the healing process of the surgical incision. Therefore, unadverted hypothermia directly influences in surgical site healing, increasing the incidence of infection in the surgical wound. PMID:25628208

OBJECTIVE To evaluate the association of airborne colony-forming units (CFU) at incision sites during implantation of prostheses with the incidence of either incisional or prosthesis-related surgical site infections. DESIGN Randomized, controlled trial. SETTING Primary, public institution. PATIENTS Three hundred patients undergoing total hip arthroplasty, instrumented spinal procedures, or vascular bypass graft implantation. METHODS Patients were randomly assigned in a 1:1 ratio to either the intervention group or the control group. A novel device (Air Barrier System), previously shown to reduce airborne CFU at incision sites, was utilized in the intervention group. Procedures assigned to the control group were performed without the device, under routine operating room atmospheric conditions. Patients were followed up for 12 months to determine whether airborne CFU levels at the incision sites predicted the incidence of incisional or prosthesis-related infection. RESULTS Data were available for 294 patients, 148 in the intervention group and 146 in the control group. CFU density at the incision site was significantly lower in the intervention group than in the control group (P<.001). The density of airborne CFU at the incision site during the procedures was significantly related to the incidence of implant infection (P=.021). Airborne CFU densities were 4 times greater in procedures with implant infection versus no implant infection. All 4 of the observed prosthesis infections occurred in the control group. CONCLUSION Reduction of airborne CFU specifically at the incision site during operations may be an effective strategy to reduce prosthesis-related infections. clinicaltrials.gov Identifier: NCT01610271 Infect Control Hosp Epidemiol 2016;1-8.

Inguinal hernia remains the most commonly encountered surgical problem. Various methods of repair have been described, and the most suitable one debated. Single port access (SPA) surgery is a rapidly evolving field, and has the advantage of affording 'scarless' surgery. Single incision laparoscopic surgery (SILS) for inguinal hernia repair is seen to be feasible in both total extraperitoneal (TEP) and transabdominal pre-peritoneal (TAPP) approaches. Data and peri-operative information on both of these however are limited. We aimed to review the clinical experience, feasibility and short term complications related to laparoscopic inguinal hernia repair via single port access. A literature search was performed using Google Scholar, Springerlink Library, Highwire Press, Surgical Endoscopy Journal, World Journal of Surgery and Medscape. The following search terms were used: laparoscopic hernia repair, TAPP, TEP, single incision laparoscopic surgery (SILS). Fourteen articles in English language related to SILS inguinal hernia repair were identified. Nine articles were related to TEP repair and the remaining 5 to TAPP. A total of 340 patients were reported within these studies: 294 patients having a TEP repair and 46 a TAPP. Only two cases of recurrence were reported. Various ports have been utilized, including the SILS port, Tri-Port and a custom- made port using conventional laparoscopic instruments. The duration of surgery was 40-100 minutes and the average length of hospital stay was one day. Early outcomes of this novel technique show it to be feasible, safe and with potentially better cosmetic outcome.

Neurosurgical application of indocyanine green (ICG) videography before performing a dural opening, known as transdural ICG videography, has been used during surgery of meningiomas associated with venous sinuses as well as cranial and spinal arteriovenous malformations. However, its use for a superficial temporal artery (STA)-to-middle cerebral artery (MCA) bypass has not been reported. We performed a retrospective analysis of medical records of patients who underwent transdural ICG videography during STA-MCA bypass performed between January 2012 and March 2015. The primary outcome was visualization of recipient cortical arteries; secondary outcomes were surgical modifications and complications as well as any adverse events associated with transdural ICG videography. We analyzed 29 STA-MCA bypass procedures performed in 30 hemispheres with atherosclerotic steno-occlusive disease and found that the proper recipient was identified in 28 hemispheres. Subsequently modified procedures for those were a tailored dural incision and craniotomy correction. No complications associated with ICG administration were encountered; during the postoperative course, transient aphasia was noted in 1 case, chronic subdural hematoma was noted in 1 case, and subdural effusion was noted in 2 cases. Transdural ICG videography for atherosclerotic steno-occlusive disease facilitates modifications during STA-MCA bypass procedures. Recognition of the proper recipient cortical arteries before a dural incision allows the neurosurgeon to perform a tailored dural incision and extension of the bone window, although the contribution to surgical outcome has yet to be determined.

Surgical techniques in managing Peyronies disease include plication corporoplasty, plaque incision, grafting and penile prosthesis implantation. The question of an ideal transplant for corporoplasty remains open. To evaluate the effectiveness of the substitution corporoplasty using buccal mucosa transplant (BMT) in treating Peyronies disease. From January 2011 to February 2016, 28 patients with stable stage Peyronies disease underwent substitution coroproplasty using BMT (incision and grafting). The mean age of patients was 54.8+/-6.2 years. All patients completed an IIEF-5 questionnaire and underwent a standard preoperative examination: anamnesis, physical examination, penile duplex pharmaco-ultrasonography and penile fixation photography to assess the type and angle of curvature. The average angle of penile curvature was 82.8 (45-120). All patients underwent incision and grafting using BMT; in 5 patients additionally the plication of the penile tunica albuginea was performed. Follow-up examinations were concluded at 3, 6 and 12 months and more after surgery. Median follow-up was 30 months. Postoperative penile straightening was achieved in 93% of patients. The duplex peak systolic velocity of the right and left cavernosal arteries improved from 42.59 to 45.64 cm/s and from 34.55 to 43.48 cm/s, respectively (p less or equal 0.05). Penile corproroplasty using BMT is a safe and effective method of treating patients with Peyronies disease. Follow-up clinical and instrumental examination showed no impairment of the erectile function or penile hemodynamics.

Minimalist breast conserving surgical approaches for inferiorly sited cancers.

PubMed

Tan, Mona P

2017-08-01

Contemporary data suggests that breast conservation treatment (BCT) may confer a survival advantage when compared to mastectomy. Hence, it would be logical to adopt strategies which increase eligibility of successful BCT without compromising oncologic principles or cosmetic outcome. With respect to achieving good aesthetics, inferiorly sited breast cancers pose a particular technical challenge. A vast array of techniques, collectively referred to as oncoplastic breast surgery (OBS) have been developed to minimise post treatment distortion. The purported advantages of these approaches are the acquisition of wider margins and reduced re-excision rates. However, to date, there is a lack of data demonstrating significant reduction in local recurrence and overall survival when compared with less extensive procedures. In this review, "minimalist" procedures are described where strict oncologic criteria of clear margins are fulfilled and acceptable cosmesis are simultaneously achieved. These techniques offer less tissue loss, less extensive parenchymal mobilisation and shorter operating times without compromising margin status and aesthetics. They involve the combination of innovative incision designs and certain parenchymal resection patterns. Incision designs include the boomerang, golf-tee, anchor and arrowhead incisions which have been previously described but not widely used. Parenchymal resection patterns follow the "sick lobe hypothesis". These techniques, termed "reductionist", or "minimalist" comprising approaches where breast conserving surgery is condensed to its irreducible elements, offer alternatives which align with contemporary objectives of surgery where optimal survival outcomes are achieved through individualised procedures resulting in reduced iatrogenic impact. This logically allows scope for de-escalation of surgical therapy for breast cancer.

Pediatric obstetrical ethics: Medical decision-making by, with, and for pregnant early adolescents.

PubMed

Mercurio, Mark R

2016-06-01

Pregnancy in an early adolescent carries with it specific ethical considerations, in some ways different from pregnancy in an adult and from medical care of a non-pregnant adolescent. Obstetrical ethics emphasizes the right of the patient to autonomy and bodily integrity, including the right to refuse medical intervention. Pediatric ethics recognizes the right of parents, within limits, to make medical decisions for their children, and the right of a child to receive medical or surgical interventions likely to be of benefit to her, sometimes over her own objections. As the child gets older, and particularly during the years of adolescence, there is also a recognition of the right to an increasingly prominent role in decisions about her own healthcare. Pediatric obstetrical ethics, referring to ethical decisions made by, with, and for pregnant early adolescents, represents the intersection of these different cultures. Principles and approaches from both obstetrical and pediatric ethics, as well as a unified understanding of rights, obligations, and practical considerations, will be needed. Copyright © 2016.

Surgical site infections (SSIs) are a leading cause of post-operative morbidity and mortality. We developed Clean Cut, a surgical infection prevention program, with two goals: (1) Increase adherence to evidence-based peri-operative infection prevention standards and (2) establish sustainable surgical infection surveillance. Here we describe our infection surveillance strategy. Clean Cut was piloted and evaluated at a 523 bed tertiary hospital in Ethiopia. Infection prevention standards included: (1) Hand and surgical site decontamination; (2) integrity of gowns, drapes, and gloves; (3) instrument sterility; (4) prophylactic antibiotic administration; (5) surgical gauze tracking; and (6) checklist compliance. Primary outcome measure was SSI, with secondary outcomes including other infection, re-operation, and length of stay. We prospectively observed all post-surgical wounds in obstetrics over a 12 day period and separately recorded post-operative complications using chart review. Simultaneously, we reviewed the written hospital charts after patient discharge for all patients whose peri-operative adherence to infection prevention standards was captured. Fifty obstetric patients were followed prospectively with recorded rates of SSI 14%, re-operation 6%, and death 2%. Compared with direct observation, chart review alone had a high loss to follow-up (28%) and decreased capture of infectious complications (SSI [n = 2], endometritis [n = 3], re-operations [n = 2], death [n = 1]); further, documentation inconsistencies failed to capture two complications (SSI [n = 1], mastitis [n = 1]). Concurrently, 137 patients were observed for peri-operative infection prevention standard adherence. Of these, we were able to successfully review 95 (69%) patient charts with recorded rates of SSI 5%, re-operation 1%, and death 1%. Patient loss to follow-up and poor documentation of infections underestimated overall infectious complications. Direct, prospective follow-up is possible but requires increased time, clinical skill, and training. For accurate surgical infection surveillance, direct follow-up of patients during hospitalization is essential, because chart review does not accurately reflect post-operative complications.

Prophylactic gastropexy is a procedure that prevents the occurrence of a life threatening condition known as gastric dilation and volvulus (GDV) in dogs. The objective of this study was to compare incisional, belt loop and minimally invasive endoscopically assisted gastropexy by evaluating different parameters such as surgical time, length of scar and score of pain in dogs. Twenty-one healthy, mixed-breed adult dogs weighting 14.3 ± 2.6 kg were randomly divided into three groups. Three gastropexy techniques applied in the following order: incisional (group I), belt loop (group B), and endoscopically assisted gastropexy (group E). Surgical time, anesthetic time, length of surgical incision and score of pain 3 h after surgery were recorded for all dogs. Two weeks after the surgery, positive-contrast gastrography was used to evaluate stomach position and total gastric emptying time. Ultrasonography was also used to evaluate the gastropexy two months after the surgery. Adhesion was confirmed two months after the surgery between the stomach wall at the pyloric antrum and the right side of the body wall in all dogs by ultrasound. The mean surgical time, length of surgical incision and score of pain were significantly lower in group E compared to group I and B (P<0.05). No significant differences were found in total gastric emptying time and gastropexy thickness post-operatively (P>0.05). Due to advantages observed in the current study, the endoscopically assisted technique seems to be a suitable alternative to open incisional and belt loop gastropexies for performing prophylactic gastropexy, especially when performed by skilled surgeons.

To evaluate the incidence of surgical site infection (SSI) based on the type of scalpel used for incisions in the skin and in subcutaneous tissues. Observer-blind, randomized equivalence clinical trial with two arms (electrocautery versus conventional scalpel) which evaluated 133 women undergoing elective abdominal gynecologic oncology surgery. A simple randomization stratified by body mass index (BMI: 30 kg/m(2)) was carried out. Women were evaluated at 14 and 30 days following the operation. A multivariate analysis was performed in order to check whether the type of scalpel would be a risk factor for SSI. Group arms were balanced for all variables, excepted for surgical time, which was significantly higher in the electrocautery group (mean: 161.1 versus 203.5 min, P = 0.029). The rates of SSI were 7.4% and 9.7%, respectively, for the conventional scalpel and electrocautery groups (P = 0.756). The exploratory multivariate model identified body mass index ≥30 kg/m(2) (OR = 24.2, 95% CI: 2.8-212.1) and transverse surgical incision (OR = 8.1, 95% CI: 1.5-42.6) as independent risk factors for SSI. The type of scalpel used in surgery, when adjusted for these variables and the surgery time, was not a risk factor for SSI. This study showed that the SSI rates for conventional scalpel and electrocautery were not significantly different. These results were consistent with others reported in the literature and would not allow a surgeon to justify scalpel choice based on SSI. NCT01410175 (Clinical Trials - NIH).

The piezoelectric device allows bone cutting without damaging the surrounding soft tissues. The purpose of this study was to assess the role of this surgical instrument in paediatric craniofacial surgery in terms of safety and surgical outcomes. Thirteen consecutive paediatric patients underwent craniofacial Le Fort osteotomies type III and IV. The saw was used on the right side in seven patients and on the left side in six patients; the piezoelectric instrument was used on the right side in six patients and on the left side in seven patients. Intraoperative blood loss, surgical procedure length, incision precision, postoperative haematoma and swelling, and nerve impairment were evaluated to compare the outcomes of both procedures. A longer surgical procedure was observed in 28% of the patients when using the piezoelectric device (p = 0.032), with an intraoperative blood loss reduction of 18% (p = 0.156). Greater precision in bone cutting was reported, together with a reduction in the requirement to protect and incise adjacent soft tissues during piezoelectric osteotomies. There was a lower incidence of postoperative haematoma and swelling following piezo-osteotomy, and a significant reduction in postoperative nerve impairment (p = 0.002). The ultrasonic surgical device guaranteed a clean bone cut, preserving the integrity of the adjacent soft tissues beneath the bone. Although the time required for a piezoelectric osteotomy was longer, the total operation time remained approximately the same. In conclusion, the device's lack of power appears to be a minor problem compared with the advantages, and an ultrasonic device could be considered a valuable instrument for paediatric craniofacial advancement.

Primary extraskeletal myxoid chondrosarcoma (EMC) of the vulva is extremely rare. There is little available information about the biological behavior and treatment strategy for primary EMC of the vulva. We report a rare case of primary EMC of the vulva treated surgically. A 24-year-old Japanese woman had demonstrated a small and elastic mass of the vulva and underwent enucleation of the mass at a previous hospital, but a definitive histopathological diagnosis was not obtained. Therefore, the patient was referred to our hospital for further evaluation and treatment. We histopathologically diagnosed the tumor as primary EMC of the vulva and performed vulvectomy with vulvoperineal reconstruction. Microscopic examination of the resected specimens demonstrated residual tumor nodules of EMC. However, there were no viable tumor cells at the surgical margin. Approximately two years after wide local excision was performed, the patient is doing well and there is no apparent recurrence of EMC. © 2011 The Authors.

Hospitalizations represent an important share of healthcare, due to both the complexity of actions and the financial volume applied. This descriptive-exploratory investigation had the purpose to identify and describing the physical and financial production of hospitalizations performed in a school hospital in the state of São Paulo, from 1996 to 2003, focusing the specialties of surgical clinic, medical clinic, pediatrics and obstetrics. Data collection was performed by searching the official databanks of the studied institution. In that period, a global 8.5% reduction in the frequency of admittances and a 78.4% increase in the financial resources were observed. Surgical clinic, with more expensive procedures, increased its admittances; the production in obstetrics showed the lowest variation. The increasing incorporation of technology, the demands from regional users and the migration of users from the supplementary system to the SUS may justify the variation of production in the different specialties.

In the first step of rhinoplasty, the surgical approach will expose through different types of incisions and dissection planes the osteocartilaginous framework of the nasal pyramid prior to performing actions to reduce or increase the latter. This exposure can be performed by a closed approach or by an external approach--the choice depends on the type of nose and the habits of the surgeon. Far from being opposites, closed and external approaches are complementary and should be known and mastered by surgeons performing rhinoplasty. Copyright © 2014 Elsevier Masson SAS.

Surgical approach for persistent ductus arteriosus ligation is typically a left lateral thoracotomy opening the pleural-space with left lung retraction. We describe an alternative approach, with a minimally invasive anterior parasternal incision. This is particularly adapted to preterm infants weighing less than 1.5 kg. This approach ensures a good exposure of vessels. We believe that it is safe, reliable and reproducible. The learning curve should not be an issue for surgeons used to manage low weight patients.

Tissue adhesives for closure of surgical incisions.

Coulthard, P; Worthington, H; Esposito, M; Elst, M; Waes, O J F

2004-01-01

Sutures, staples and adhesive tapes are the traditional methods of wound closure, whilst tissue adhesives have entered clinical practice more recently. Closure of wounds with sutures enables meticulous closure, but sutures may induce tissue reactivity and they usually require removal. Tissue adhesives offer the advantages there are no sutures to remove later for the patient and no risk of needlestick injury to the surgeon. Tissue adhesives have been used primarily in emergency rooms but this review looks at the use of tissue adhesives in the operating room where surgeons are increasingly using these for the closure of surgical skin incisions. To determine the relative effects of various tissue adhesives and conventional skin closure techniques on the healing of surgical wounds. The Cochrane Wounds Group Specialised Trials Register, The Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE were searched. Bibliographies of review articles were checked for studies outside the handsearched journals and wound care product manufacturers were contacted. Randomised controlled clinical trials only. Screening of eligible studies and data extraction was conducted independently and in triplicate whilst assessment of the methodological quality of the trials was conducted independently and in duplicate. Results were expressed as random effect models using weighted mean differences for continuous outcomes and relative risk with 95% confidence intervals for dichotomous outcomes. Heterogeneity was investigated including both clinical and methodological factors. Eight RCTs were included (630 patients). No statistically significant differences were found between various tissue adhesives and sutures (8 trials) for dehiscence, infection, satisfaction with cosmetic appearance when assessed by patients' or surgeons' general satisfaction. Nor were differences found between a tissue adhesive and tapes (2 trials) for infection, patients' assessment of cosmetic appearance, patient satisfaction or surgeon satisfaction. However a statistically significant difference was found for surgeons' assessment of cosmetic appearance with mean difference 13 (95%CI 5 to 21), the higher mean rating for the tissue adhesive group. Surgeons may consider the use of tissue adhesives as an alternative to sutures or adhesive tape for the closure of incisions in the operating room. There is a need for trials in all areas but in particular to include patients that require incision closure in areas of high tension and patients of general health that may impair wound healing.

Over the last years, less invasive surgical techniques with soft tissue preservation for bone conduction hearing implants (BCHI) have been introduced such as the linear incision technique combined with a punch. Results using this technique seem favorable in terms of rate of peri-abutment dermatitis (PAD), esthetics, and preservation of skin sensibility. Recently, a new standardized surgical technique for BCHI placement, the Minimally Invasive Ponto Surgery (MIPS) technique has been developed by Oticon Medical AB (Askim, Sweden). This technique aims to standardize surgery by using a novel surgical instrumentation kit and minimize soft tissue trauma. A multicenter randomized controlled trial is designed to compare the MIPS technique to the linear incision technique with soft tissue preservation. The primary investigation center is Maastricht University Medical Center. Sixty-two participants will be included with a 2-year follow-up period. Parameters are introduced to quantify factors such as loss of skin sensibility, dehiscence of the skin next to the abutment, skin overgrowth, and cosmetic results. A new type of sampling method is incorporated to aid in the estimation of complications. To gain further understanding of PAD, swabs and skin biopsies are collected during follow-up visits for evaluation of the bacterial profile and inflammatory cytokine expression. The primary objective of the study is to compare the incidence of PAD during the first 3 months after BCHI placement. Secondary objectives include the assessment of parameters related to surgery, wound healing, pain, loss of sensibility of the skin around the implant, implant extrusion rate, implant stability measurements, dehiscence of the skin next to the abutment, and esthetic appeal. Tertiary objectives include assessment of other factors related to PAD and a health economic evaluation. This is the first trial to compare the recently developed MIPS technique to the linear incision technique with soft tissue preservation for BCHI surgery. Newly introduced parameters and sampling method will aid in the prediction of results and complications after BCHI placement.

Surgical site infection is one of the most common complications for patients after sacrectomy, which often accompanied by poor wound healing, sinus formation and serious metabolic disturbance. We tried to avoid the surgical site infection caused by feces during early period after surgery through early fasting and total parenteral nutrition (TPN) support, then compared the clinical results of these patients with other patients that received enteral nutrition (EN) early after sacrectomy. Forty-eight patients after sacrectomy (the level of sacrectomy above S 2 ) were randomly divided into two groups: TPN group and EN group. The patients of two groups received different nutrition support from the first day to the seventh day after surgery, then the factors such as nutritional and metabolic status after surgery, incidence of complications as well as the time of incision healing and hospitalization were observed. The p-value of total serum protein, albumin, serum alanine aminotransferase, total bilirubin at seventh day after sacrectomy between TPN group and EN group is <0.0005. The p-value of hemoglobin at seventh day after sacrectomy between TPN group and EN group is 0.001. The p-value of total serum protein at fourteenth day after sacrectomy between TPN group and EN group is 0.003. The p-value of albumin and total bilirubin at fourteenth day after sacrectomy between TPN group and EN group is 0.001. The p-value of hemoglobin, serum alanine aminotransferase at fourteenth day after sacrectomy between TPN group and EN group is <0.0005. The incidence of gastrointestinal complication and delay of apparition of feces in EN group were lower than that in TPN group (p=0.041, p<0.0005). The incidence of surgical site infection, the time of incision healing and hospitalization in TPN group were lower than that in EN group (p=0.048, p=0.008, p<0.0005). The method of fasting and supported by TPN during the early period after sacrectomy contribute to the incision healing, meanwhile, it shortens the hospitalization time and abates the incidence of complications in patients after sacrectomy.

To assess the effects of tranexamic acid among patients undergoing cesarean delivery who were at high risk of postpartum hemorrhage. Between August 1, 2012, and April 30, 2013, a randomized controlled trial was performed at a tertiary care center in India. Women undergoing an elective or emergency cesarean delivery who were at high risk for postpartum hemorrhage were enrolled. They were randomly assigned using sealed, opaque envelopes to receive 10mg/kg tranexamic acid or normal saline 10min before skin incision. Anesthesiologists were not masked to group assignment, but patients and obstetricians were. The primary outcome was need for additional uterotonic drugs within 24h after delivery. Analyses were by intention to treat. Thirty patients were assigned to each group. Additional uterotonic drugs were required in 7 (23%) patients assigned to tranexamic acid and 25 (83%) patients in the control group (P<0.001). Intravenous tranexamic acid, administered before skin incision, significantly reduced the requirement for additional uterotonics among women at increased risk for postpartum hemorrhage.

Cleft Palate Repair Using a Double Opposing Z-Plasty.

PubMed

Moores, Craig; Shah, Ajul; Steinbacher, Derek M

2016-07-01

Cleft palate is a common congenital defect with several described surgical repairs. The most successful treatment modality remains a controversy. The goals of repair focus on achievement of normal speech and optimizing velopharyngeal function while minimizing both fistula formation and facial growth restriction. In this video, the authors demonstrate use of the double opposing Z-plasty technique in the repair of a Veau II type cleft palate. The video demonstrates the marking, incisions, dissection, and repair of the cleft. It also examines the use of von Langenbeck-type relaxing incisions and demonstrates a specific approach to the repair of this particular cleft. The authors believe that the Furlow double opposing Z-plasty with the von Langenbeck relaxing incision can provide the best postoperative outcome by combining the benefits of each individual operation. The Z-plasty technique works to correct the aberrant muscle of the soft palate while increasing the length of the palate. The authors believe that this results in better velopharyngeal function.

Antimicrobial Prophylaxis in Adults

Enzler, Mark J.; Berbari, Elie; Osmon, Douglas R.

2011-01-01

Antimicrobial prophylaxis is commonly used by clinicians for the prevention of numerous infectious diseases, including herpes simplex infection, rheumatic fever, recurrent cellulitis, meningococcal disease, recurrent uncomplicated urinary tract infections in women, spontaneous bacterial peritonitis in patients with cirrhosis, influenza, infective endocarditis, pertussis, and acute necrotizing pancreatitis, as well as infections associated with open fractures, recent prosthetic joint placement, and bite wounds. Perioperative antimicrobial prophylaxis is recommended for various surgical procedures to prevent surgical site infections. Optimal antimicrobial agents for prophylaxis should be bactericidal, nontoxic, inexpensive, and active against the typical pathogens that can cause surgical site infection postoperatively. To maximize its effectiveness, intravenous perioperative prophylaxis should be administered within 30 to 60 minutes before the surgical incision. Antimicrobial prophylaxis should be of short duration to decrease toxicity and antimicrobial resistance and to reduce cost. PMID:21719623

This study aimed to evaluate the clinical effect of extramedullary fixation combined with intramedullary fixation during the surgical reduction of sagittal mandibular condylar fractures. Twenty-four sagittal fractures of the mandibular condyle in18 patients were fixed by two appliances: intramedullary with one long-screw osteosynthesis or Kirschner wire and extramedullary with one micro-plate. The radiologically-recorded post-operative stability-associated com-plications included the screw/micro-plate loosening, micro-plate twisting, micro-plate fractures, and fragment rotation. The occluding relations, the maximalinter-incisal distances upon mouth opening, and the mandibular deflection upon mouth opening were evaluated based on follow-up clinical examination. Postoperative panoramic X-ray and CT scans showed good repositioning of the fragment, with no redislocation or rotation, no screw/plate loosening, and no plate-twisting or fracture. Clinical examination showed that all patients regained normal mandibular movements, ideal occlusion, and normal maximal inter-incisal distances upon mouth opening. Extramedullary fixation combined with intramedullary fixation is highly recommended for sagittal condylar fractures because of the anti-rotation effect of the fragment and the reasonable place-ment of the fixation appliances.

To identify the clinical and anatomical presentations and to discuss the guidelines for surgical management of anomalies of the first branchial cleft. Twenty-one patients with first branchial cleft anomalies were treated in our department between January 1994 and December 2004, their clinical data were retrospectively analysed. Surgery was performed on all patients. Among them 13 were males and 8 females, ranging in age from 1.5 to 33 years with an average of 15 years. Anatomically, 3 types of first branchial cleft anomalies were identified: fistulas (n = 17), cysts (n = 2), and fistula combined with cyst (n = 2). Before definitive surgery, soma patients (n = 4) underwent incision and drainage for infection owing to the difficulties in diagnosing this anomaly. Methylthioninium Chloride was used in almost all cases for tracking the fistulous during operation. Wide exposure is necessary in many cases,and a standard parotidectomy incision allows adequate exposure of the anomaly and preservation of the facial nerve. Complete removal without complications depends on a good understanding of regional embryogenesis, an awareness of the different anatomical presentations, and a readiness to identify and protect the facial nerve during resection.

Gynecomastia refers to a benign enlargement of the male breast. This article describes the authors' method of using power-assisted liposuction and gland removal through a subareolar incision for thin patients. Power-assisted liposuction is performed for removal of fatty breast tissue in the chest area to allow skin retraction. The subareolar incision is used to remove glandular tissue from a male subject considered to be within a normal weight range but who has bilateral grade 1 or 2 gynecomastia. Gynecomastia correction was successfully performed for all the patients. The average volume of aspirated fat breast was 100-200 ml on each side. Each breast had 5-80 g of breast tissue removed. At the 3-month, 6-month, and 1-year follow-up assessments, all the treated patients were satisfied with their aesthetic results. Liposuction has the advantages of reducing the fat tissue where necessary to allow skin retraction and of reducing the traces left by surgery. The combination of surgical excision and power-assisted lipoplasty also is a valid choice for the treatment of thin patients.

Unisurgeon’ uniportal video-assisted thoracoscopic surgery lobectomy

PubMed Central

2017-01-01

The video-assisted thoracoscopic surgery (VATS) for major pulmonary resections has evolved in a period of only 7 years from 3–4 incisions to a single incision approach. However, Uniportal VATS approach is different from other forms of minimally invasive thoracic surgery, and the technique of lung exposure and stapler insertion through a single hole should be learned step by step. The main advances of uniportal VATS during the last years are related to improvements in surgical technique, evolving to a concept of “advanced VATS instrumentation”, and implementation of new technology. One recent advance in uniportal VATS is the possibility of using a robotic or pneumatic articulated arm that holds the camera stable and no needs a surgical assistant. This is called “unisurgeon uniportal VATS” in where the surgeon has more freedom of movements and eliminates the fatigue of assistant holding the camera. We are still in the beginning of the “unisurgeon era” that probably will be more popular in the next coming years thanks to the Implementation of wireless cameras and graspers by means of magnetic control.

To analyze our surgical management and the result of squamous cell carcinoma (SCC) of vulva. Retrospectively, we collected 38 cases of SCC; 17 cases of them were early SCC and 21 cases were locally advanced. The patients underwent primary surgery. The survival was estimated using Kaplan-Meier analysis and the log rank test. The mean age was 60.78 years. Total vulvectomy was performed in all patients. Superficial and deep incision of bilateral inguinal lymphadenectomy was performed by separates incisions for SCC infiltrating more than 1mm. The average tumor size was 53 mm (10 to 140mm). Morbidity was 42.1%. Lateral resection margin ≥8mm was obtained in 57.1%. Eighteen patients benefited from adjuvant radiotherapy. The follow-up median was 19.4 months (6 to 61.5 month) with 05 recurrences in 12 months. The survival using the Kaplan-Meyer analysis at 5 years, was 62.1% (71.2%N(-) vs 46.7%N(+); p = 0.13). We identified two groups for locally advanced vulva cancer. Primary surgery keeps its place. Neo adjuvant radio chemotherapy followed by surgery is the alternative treatment for locally extensive lesions.

Minimally invasive therapy (MIT) is one of the most important trends in modern medicine. It includes a wide range of therapies in videoscopic surgery and interventional radiology and is performed through small incisions. It reduces hospital stay-time by allowing faster recovery and offers substantially improved cost-effectiveness for the hospital and the society. However, the introduction of MIT has also led to new problems. The manipulation of structures within the body through small incisions reduces dexterity and tactile feedback. It requires a different approach than conventional surgical procedures, since eye-hand co-ordination is not based on direct vision, but more predominantly on image guidance via endoscopes or radiological imaging modalities. ARIS*ER is a multidisciplinary consortium developing a new generation of decision support tools for MIT by augmenting visual and sensorial feedback. We will present tools based on novel concepts in visualization, robotics and haptics providing tailored solutions for a range of clinical applications. Examples from radio-frequency ablation of liver-tumors, laparoscopic liver surgery and minimally invasive cardiac surgery will be presented. Demonstrators were developed with the aim to provide a seamless workflow for the clinical user conducting image-guided therapy.

To examine the status of resident training in robotic surgery in obstetrics and gynecology programs in the United States, an online survey was emailed to residency program directors of 247 accredited programs identified through the Accreditation Council for Graduate Medical Education website. Eighty-three of 247 program directors responded, representing a 34% response rate. Robotic surgical systems for gynecologic procedures were used at 65 (78%) institutions. Robotic surgery training was part of residency curriculum at 48 (58%) residency programs. Half of respondents were undecided on training effectiveness. Most program directors believed the role of robotic surgery would increase and play a more integral role in gynecologic surgery. Robotic surgery was widely reported in residency training hospitals with limited availability of effective resident training. Robotic surgery training in obstetrics and gynecology residency needs further assessment and may benefit from a structured curriculum. Published by Elsevier Inc.

To evaluate the intraoperative performance and postoperative outcomes after microcoaxial phacoemulsification. Iladevi Cataract & IOL Research Centre, Ahmedabad, India. A prospective observational case series comprised 84 eyes with age-related uncomplicated cataract having microcoaxial phacoemulsification through a 2.2 mm clear corneal incision by a standard surgical technique. Phacoemulsification parameters (Infiniti Vision System, Alcon) were microburst width, 30 ms; preset power, 50%; vacuum, 650 mm Hg; aspiration flow rate, 25 cc/minute. A single-piece Alcon AcrySof intraocular lens was implanted with the C cartridge (Alcon) cartridge. The incision was measured at the end of surgery. Observations included surgical time (from commencement of sculpting to end of epinucleus removal), cumulative dissipated energy (CDE), wound burns, intraoperative complications, postoperative increase in mean central corneal thickness (CCT) at 1 day and 1 month, mean % decrease in endothelial cell density (ECD), absolute mean change in coefficient of variation (cv) 3 months, and uncorrected visual acuity (UCVA) at 1 day. Data were analyzed using a 1-sample t test with 95% confidence intervals (CIs). The mean follow up was 3 months +/- 0.3 (SD). The mean incision size at the end of surgery was 2.3 +/- .09 mm; mean surgical time, 4.5 +/- 1.5 minutes; and mean CDE, 2.3 +/- 2.2 seconds. No wound burns or other intraoperative complications occurred. The postoperative CCT increased by a mean of 16 microm at 1 day (95% CI, 8-25; P = .66;) and by a mean of 3.14 microm at 1 month (95% CI, 2.26-4.05; P = .92). The ECD decreased by a mean of 5.8% (95% CI, 6.8-3.5; P = .82) and the mean coefficient of variation, by 3.3 (95% CI, 4.5-2.0; P = .65). At 1 day, the UCVA was 20/20 in 29% of cases, 20/20 to 20/40 in 58%, and 20/40 to 20/50 in 12%. Microcoaxial phacoemulsification was safely and effectively performed, achieving consistent and satisfactory postoperative outcomes.

Recurrent hepatocellular carcinoma accompanied by a right atrial tumor thrombus is rare. No standard treatment modality has been established. Surgical treatment may be the only curative treatment; however, surgery has been considered high risk. We herein describe a patient who underwent resection of a recurrent right atrial tumor thrombus under normothermic cardiopulmonary bypass on a beating heart. A 60-year-old man underwent a right hepatectomy for hepatocellular carcinoma with diaphragm invasion. During the preoperative cardiac screening, he was diagnosed with an old myocardial infarction with triple-vessel coronary disease. Percutaneous coronary intervention was performed for the left anterior descending artery and left circumflex coronary artery. High-grade stenosis remained in his right coronary artery. Nine months later, computed tomography showed recurrent hepatocellular carcinoma in the diaphragm and a tumor thrombus extending from the suprahepatic inferior vena cava into the right atrium. Surgical resection of the recurrent tumor was performed through a right subcostal incision with xiphoid extension and median sternotomy. The recurrent tumor was incised with the diaphragm and pericardium. Intraoperative ultrasonography revealed that the tumor thrombus was free from right atrium wall invasion and that the right atrium could be clamped just proximal to the tumor thrombus. The right atrium, infrahepatic vena cava, left and middle hepatic veins, and hepatoduodenal ligament were encircled. Cardiopulmonary bypass was performed to prevent ischemic heart disease caused by intraoperative hypotension. Total hepatic vascular exclusion was then performed under normothermic cardiopulmonary bypass on heart beating. The inferior vena cava wall was incised. The tumor thrombus with the diaphragmatic recurrent tumor was resected en bloc. The patient had a favorable clinical course without any complications. The recurrent hepatocellular carcinoma in the diaphragm and the right atrial tumor thrombus were safely resected using normothermic cardiopulmonary bypass on heart beating.

Background Accumulating studies have suggested that remifentanil, the widely-used opioid analgesic in clinical anesthesia, can activate the pronociceptive systems and enhance postoperative pain. Glial cells are thought to be implicated in remifentanil-induced hyperalgesia. Electroacupuncture is a complementary therapy to relieve various pain conditions with few side effects, and glial cells may be involved in its antinociceptive effect. In this study, we investigated whether intraoperative electroacupuncture could relieve remifentanil-induced postoperative hyperalgesia by inhibiting the activation of spinal glial cells, the production of spinal proinflammatory cytokines, and the activation of spinal mitogen-activated protein kinases. Methods A rat model of remifentanil-induced postoperative hyperalgesia was used in this study. Electroacupuncture during surgery was conducted at bilateral Zusanli (ST36) acupoints. Behavior tests, including mechanical allodynia and thermal hyperalgesia, were performed at different time points. Astrocytic marker glial fibrillary acidic protein, microglial marker Iba1, proinflammatory cytokines, and phosphorylated mitogen-activated protein kinases in the spinal cord were detected by Western blot and/or immunofluorescence. Results Mechanical allodynia and thermal hyperalgesia were induced by both surgical incision and remifentanil infusion, and remifentanil infusion significantly exaggerated and prolonged incision-induced pronociceptive effects. Glial fibrillary acidic protein, Iba1, proinflammatory cytokines (interleukin-1β and tumor necrosis factor-α), and phosphorylated mitogen-activated protein kinases (p-p38, p-JNK, and p-ERK1/2) were upregulated after surgical incision, remifentanil infusion, and especially after their combination. Intraoperative electroacupuncture significantly attenuated incision- and/or remifentanil-induced pronociceptive effects, spinal glial activation, proinflammatory cytokine upregulation, and phosphorylated mitogen-activated protein kinase upregulation. Conclusions Our study suggests that remifentanil-induced postoperative hyperalgesia can be relieved by intraoperative electroacupuncture via inhibiting the activation of spinal glial cells, the upregulation of spinal proinflammatory cytokines, and the activation of spinal mitogen-activated protein kinases.

Surgeons continually strive to improve technology and patient care. One remarkable demonstration of this is the development of laparoscopic surgery. Once this proved to be a safe and reliable surgical approach, robotics seemed a logical progression of surgical technology. The aim of this project was to evaluate the utility of robotics in the context of single-incision laparoscopic cholecystectomy (SILC). A retrospective review of a prospectively maintained database of robotic single-incision laparoscopic cholecystectomy (RSILC) and traditional SILC performed by a single surgeon at our institution from July 2010 to August 2013 was queried. All consecutive patients undergoing RSILC and SILC during this time period were included. Primary outcomes include conversion rate and operative time. Secondary outcomes include length of stay, duration of narcotic use, time to independent performance of daily activities and cost. Categorical variables were evaluated using Chi-square analysis and continuous variables using t test or Wilcoxon's rank test. Thirty-eight patients underwent RSILC and 44 underwent SILC. BMI was higher in the RSILC group, and the number of patients with prior abdominal surgeries was higher in the SILC group. Otherwise, demographics were similar between the two groups. There was no difference in conversion rate between RSILC and SILC (8 vs 11 %, p = 0.60). Mean operative time for RSILC was significantly greater compared with SILC (98 vs 68 min, p < 0.0001). RSILC was associated with a longer duration of narcotic use (2.3 vs 1.7 days, p = 0.0019) and time to independent performance of daily activities (4 vs 2.3 days, p < 0.0001). Total cost is greater in RSILC ($8961 vs $5379, p < 0.0001). While RSILC can be safely performed, it is associated with longer operative times and greater cost.

Complete placenta previa (CPP) is one of the most problematic types of abnormal placenta, which is further complicated by placenta accreta or percreta that can unexpectedly lead to catastrophic blood loss, infection, multiple complications, emergency hysterectomy, and even death. The present study aimed to assess the efficacy of random placenta margin incision in controlling intraoperative and total blood loss during cesarean section for CPP women. A prospective cohort study, including a total of 100 consecutive pregnant women with CPP, was performed at a tertiary university-affiliated medical center between March 2016 and July 2017. All of them underwent random placenta margin incision, and intraoperative and total blood loss were analyzed. Through antenatal diagnosis using color Doppler, women were further divided into abnormally invasive placenta (AIP) and non-AIP groups, and anterior and posterior placenta groups. The protocol was registered with the Clinical Trial Registry under registration number NCT02695069. Mean maternal age and gestational age at delivery were 32.26 ± 5.03 years old and 36.21 ± 2.07 weeks, respectively. Total duration of the surgical procedure time was 52.50 (42.43-64.00) min. Median estimated intraoperation blood loss was 746.43 (544.44-1092.86) ml. Total blood loss was 875.00 (604.50-1196.67) ml, and 38 (38.0%) had post-partum hemorrhage. The change from baseline in the median hemoglobin level was -0.33 (6.00-13.20). No women underwent hysterectomy due to massive hemorrhage during the study period. No women had an intraoperative urinary bladder injury, postoperative wound infection, and required relaparotomy, owing to intra-abdominal bleeding. The median hospitalization time was 5.41 (4.18-7.58) d. The random placenta margin incision may be a potentially valuable surgical procedure to control the volumes of intraoperative and postoperative blood loss and reduce the incidence of postpartum hemorrhage among women with complete placenta previa.

The aim of this study is to describe the surgical technique, and assess the complications and middle-term results of the Contasure Needleless (Neomedic International), a single incision TOT sling for the surgical treatment of stress urinary incontinence. The main concept of this device is that it is not a mini-sling, it has 138% more surface area. We are analyzing the results of a minimally invasive solution that is a TOT like sling with the same known benefits of a TOT and the advantages of a single incision technique. The surface area to support the urethra of the Needleless is very similar to the surface area of the TOT. (16% less surface area of tissue ingrowths) It is 100% macroporous polypropylene without any additional material. 120 patients were evaluated retrospectively. They were all treated of SUI with the Contasure Needleless.Female patients were evaluated under clinical study protocol consisting in cough test, urodynamic and Quality Of Life questionnaire, before and after the procedure. patients with genuine SUI and patients with SUI plus concomitant procedures as prolapse. patients with ISD and or neurogenic incontinence. Anesthesia used: general (30%) or epidural (70%), patients with associated pathology. The 114 mm long and tension-free mesh was placed beneath the midurethra. The central part is 12 mm wide. The sling can be repositioned during surgery due to the 22 mm wide T-Pocket Positioning System located at the 2 edges. These pockets fixed the sling to the surrounding tissue in order to have the proper tissue in growth and anchoring. A 20mm sub urethral incision was made to dissect the paraurethral spaces only up to the ischiopubic ramus. A surgical forceps with the T-pocket folded was inserted into the dissected spaces and penetrates at the contra lateral side, like the standard transobturator technique. The forceps was introduced until the fascia of the Internal Obturator muscle was perforated. Then the forceps is opened to extend the pocket inside the muscle fibers for fixation. 120 patients with a mean age of 55 years (from 36 to 79) and a mean number of deliveries of 3 (0-7). Follow-up period: 24 months. SUCCESS RATE: 100 patients (84%) Improved rate: 10 patients (8%) Failure rate: 10 (8%) Mean operating time of sling procedure alone: 9 minutes (4-12). 3 patients had mesh extrusion solved with estrogens and 2 patients required short term catheterization due to voiding difficulties and no patients had inguinal pain. The results of the study suggest that the Contasure Needleless can be considered a minimally invasive TOT with no-needles and maintaining the same cure rate than our TOT cases at 2 years follow up.

Background and Objectives: Until the advent of single-incision laparoscopic surgery, few advances were aimed at improving cosmesis with laparoscopic cholecystectomy. Criticisms of the single-incision laparoscopic surgery technique include a larger incision and increased incidence of wound-related complications. We present our initial experience with a novel technique aimed at performing strategic laparoscopy for improved cosmesis (SLIC) for cholecystectomy. Methods: Twenty-five patients with biliary symptoms were selected for SLIC cholecystectomy. Access to the abdomen was obtained with a 5-mm optical trocar in the left upper quadrant and a 5-mm trocar in the umbilicus. Retraction was performed by a transabdominal suture in the dome of the gallbladder and a needlescopic grasper. Age, American Society of Anesthesiologists score, body mass index, operative time, length of stay, pathology results, and short-term complications at follow-up were prospectively recorded. Results: The 25 female patients had a mean age of 34.3 years and mean body mass index of 24 kg/m2. American Society of Anesthesiologists scores ranged from 1 to 3. The mean operative time was 51.3 minutes. Pathology revealed chronic cholecystitis in all patients. All procedures were performed on an outpatient basis. The only complication was one ultrasonography-documented deep vein thrombosis. All 25 planned SLIC cholecystectomies were successfully completed. Conclusions: SLIC cholecystectomy is feasible and safe. This technique decreases the cumulative incision length, as well as the number of incisions, leading to very desirable cosmetic results in patients with a favorable body habitus and surgical history.

Approximately half of all patients who undergo surgery develop postoperative pain, the mechanisms of which are not well understood by anesthesiologists. D2-like receptors in the descending dopaminergic pathway play an important role in regulation of pain transmission in the spinal cord. Impairment of inhibitory neurons in the spinal cord is suggested as part of the mechanism for neuropathic pain, which is one component of postoperative pain. The purpose of this study was to investigate whether impairment of D2-like receptors in the descending dopaminergic pathway in the spinal cord is involved in the decreased postoperative nociceptive threshold in rats. Male Sprague-Dawley rats (250-300 g) were anesthetized with sevoflurane and an intrathecal (IT) catheter was implanted. Six days later, a plantar incision was made. On the following day, saline, a D2-like receptor agonist (quinpirole), or a D2-like receptor antagonist (sulpiride) was administered intrathecally. Thermal and mechanical nociceptive responses were assessed by exposure to infrared radiant heat and the von Frey filament test before and after plantar incision. Plantar incision decreased both thermal latency and the mechanical nociceptive threshold. IT administration of quinpirole inhibited the nociceptive responses induced by plantar incision, but sulpiride had no effect. A D2-like receptor agonist had antinociceptive effects on the hypersensitivity response triggered by a surgical incision, but a D2-like receptor antagonist had no effect on this response. These results suggest that impairment and/or modification of D2-like receptors in the descending dopaminergic pathway in the spinal cord is not involved in the postoperative decrease in nociceptive threshold.

Abstract Backgrounds: The harvesting of great saphenous veins for coronary artery bypass graft (CABG) patients may result in significant complications, including lymphorrhagia, lymphoedema, incision infection, wound dehiscence, and skin flap necrosis. We investigated the function of a self-designed bilayered negative pressure wound therapy (b-NPWT) for reducing the above-mentioned complications using a clinical randomized controlled trial. Methods: A single-center, pilot randomized controlled trial was conducted. From December 2013 to March 2014, a total of 72 coronary heart disease patients (48 men and 24 women) received CABG therapy, with great saphenous veins were selected as grafts. Patients were equally randomized into a treatment and a control group. After the harvesting of the great saphenous veins and direct closure of the wound with sutures, b-NPWT was used for the thigh incision in the treatment group for 5 days (treatment thigh). Traditional surgical pads were applied to both the shank incisions of the treatment group patients (treatment shank) and the entire incisions of the control group (control thigh, control shank). Postoperative complications were recorded and statistically analyzed based on outcomes of thigh treatment, shank treatment, thigh control, and shank control groups. Results: The incidence rates of early complications, such as lymphorrhagia, lymphoedema, infection, wound dehiscence, and skin flap necrosis, of the vascular donor site in the thigh treatment group was significantly lower than those in the 3 other groups. Conclusions: The self-designed b-NPWT can effectively reduce postoperative complications, such as lymphedema, incision infection, wound dehiscence, and skin flap necrosis, in CABG patients who underwent great saphenous veins harvesting. Trial registration: ClinicalTrials.gov. The unique registration number is NCT02010996. PMID:28099357

This study demonstrated the effects of traumatic brain injury (TBI) and each step of the surgical procedure for a fluid percussion injury (FPI) model on periorbital allodynia. Adult male Wistar rats were divided in naive, incision, scraping, sham-TBI and TBI groups. Periorbital allodynia was evaluated using von Frey filaments, and heat hyperalgesia of the hindpaws was evaluated by a Plantar Test Apparatus. The statistical analyses revealed that the surgical procedure decreased von Frey filaments thresholds twenty-four hours after the surgery in all groups when compared to the naive group (p < 0.0001). Scraping, sham-TBI and TBI groups showed a decrease in the periorbital mechanical threshold for 35 days compared with the naive and incision groups (p < 0.0001). Only the TBI group demonstrated a significant difference in periorbital allodynia at 45 and 60 days after the injury (p < 0.01). A significant decrease in the thermal withdrawal latency of the hindpaw contralateral to the lesion was observed in the TBI group compared with the naïve group at 7 days and 28 days after the lesion (p < 0.05). This study presented in detail the effects of each stage of the surgical procedure for a FPI model on periorbital allodynia over time and characterized the TBI model for this evaluation. The FPI model is relevant for the study of headache and generalized pain in both acute and chronic phases after an injury. Copyright © 2018 Elsevier B.V. All rights reserved.

Stabilizing techniques for flail chest injuries are described through wide surgical approaches to the chest wall, especially in the most affected posterior and lateral regions. Severe morbidity due to these invasive approaches needs to be considered due to dissection of the scapular guiding muscles and the risk of injuries to neurovascular bundles. This study discusses possibilities for minimized approaches to the posterior and lateral regions. Ten fresh-frozen cadavers in lateral decubitus position were observed on both sides. Each surgical arm was kept mobile during the procedure. Approaches were performed following a standard protocol with muscle-sparing incisions starting with 5 cm in length and extending to 10 and 15 cm. The accessible surface comparing the extensions was measured. Visible ribs were counted. In a next step, MatrixRib ® Plates were fixed to those ribs to prove the feasibility of rib stabilization through limited approaches. Combinations of the posterior and lateral minimized approaches allow surgical fixation of 6-9 and 7-11 ribs through 5 and 10 cm incisions, respectively. In the case of an extreme expansion of a rib fracture series, an access extension can be made to 15 cm to be able to adequately supply the entire hemithorax using two approaches. Extensive invasive surgical approaches to the thoracic wall can be replaced by reduced invasive and muscle-sparing access combinations. A free-moving positioning of the arm and an accurate preoperative plan for minimizing approaches are essential. Minimally invasive plate techniques are very helpful adjuncts.

Vaginal-sparing ventral buccal mucosal graft urethroplasty for female urethral stricture: A novel modification of surgical technique

Purpose To present a novel modification of surgical technique to treat female urethral stricture (FUS) by a vaginal-sparing ventral buccal mucosal urethroplasty. Recurrent FUS represents an uncommon, though difficult clinical scenario to manage definitively. A variety of surgical techniques have been described to date, yet a lack of consensus on the optimal procedure persists. Materials and Methods We present a 51-year-old female with urethral stricture involving the entire urethra. Suspected etiology was iatrogenic from cystoscopy 17 years prior. Since then, the patient had undergone at least 25 formal urethral dilations and periods of self-dilation. In lithotomy position, the urethra was dilated to accommodate forceps, and ventral urethrotomy carried out sharply, exposing a bed of periurethral tissue. Buccal mucosa was harvested, and a ventral inlay technique facilitated by a nasal speculum, was used to place the graft from the proximal urethra/bladder neck to urethral meatus without a vaginal incision. Graft was sutured into place, and urethral Foley catheter inserted. Results The vaginal-sparing ventral buccal mucosal graft urethroplasty was deemed successful as of last follow-up. Flexible cystoscopy demonstrated patency of the repair at 6 months. At 10 months of follow-up, the patient was voiding well, with no urinary incontinence. No further interventions have been required. Conclusions This case describes a novel modification of surgical technique for performing buccal mucosal urethroplasty for FUS. By avoiding incision of the vaginal mucosa, benefits may include reduced: morbidity, urinary incontinence, and wound complications including urethro-vaginal fistula. PMID:27437540

The Role of Minimally Invasive Plate Osteosynthesis in Rib Fixation: A Review

Bemelman, Michael; van Baal, Mark; Yuan, Jian Zhang; Leenen, Luke

2016-01-01

More than a century ago, the first scientific report was published about fracture fixation with plates. During the 1950’s, open reduction and plate fixation for fractures were standardized by the founders of Arbeitsgemeinschaft für osteosynthesefragen/Association for the Study of Internal Fixation. Since the introduction of plate fixation for fractures, several plates and screws have been developed, all with their own characteristics. To accomplice more fracture stability, it was thought the bigger the plate, the better. The counter side was a compromised blood supply of the bone, often resulting in bone necrosis and ultimately delayed or non-union. With the search and development of new materials and techniques for fracture fixation, less invasive procedures have become increasingly popular. This resulted in the minimally invasive plate osteosynthesis (MIPO) technique for fracture fixation. With the MIPO technique, procedures could be performed with smaller incisions and thus with less soft tissue damage and a better preserved blood supply. The last 5 years rib fixation has become increasingly popular, rising evidence has become available suggesting that surgical rib fixation improves outcome of patients with a flail chest or isolated rib fractures. Many surgical approaches for rib fixation have been described in the old literature, however, most of these techniques are obscure nowadays. Currently mostly large incisions with considerable surgical insult are used to stabilize rib fractures. We think that MIPO deserves a place in the surgical treatment of rib fractures. We present the aspects of diagnosis, preoperative planning and operative techniques in regard to MIPO rib fixation. PMID:26889439

This study aimed to investigate the spread of methicillin-resistant coagulase-positive staphylococci (MRCoPS) among veterinary staff, hand-touch sites and surgical tissue during cystotomy operations on cats and dogs that were patients, and to analyze the genetic relatedness and antimicrobial resistance profiles of the isolates. Human and environmental samples were obtained from the nasal passageways of 12 surgeons and veterinary assistants and from 29 hand-touch sites of instruments in operative units and subjected to bacterial isolation and enumeration. Swab samples were collected in triplicate from 29 dogs and three cats at the site of incision, from the incision area, from the peritoneum during surgery and from the peritoneum before suture. MRCoPS were identified by mecA gene detection and characterized by their antibiogram profile, SCCmec type and pulsed-field gel electrophoresis. Twenty-four staphylococci were isolated, derived from one veterinary assistant, 12 operating room floor areas and hand-touch sites, three dogs and one cat. Methicillin-resistant S. pseudintermedius (MRSP) was found on an electric clipper and rebreathing circuits in the operating room. Three dogs were positive for MRSP during surgery, and one methicillin-resistant S. aureus (MRSA) was detected in a cat. All MRCoPS were resistant to doxycycline, erythromycin, clindamycin and enrofloxacin, but no patients developed surgical site infections. According to their genotypic patterns, the clones obtained from the environment and human sources differed from the animal clones. Despite intensive hygienic management, a variety of MRCoPS clones were present within the surgical unit and during surgery. PMID:27990009

A review of Dr. Cushing's surgical cases at Johns Hopkins Hospital revealed new information about his early operative experience with acromegaly. Although in 1912 Cushing published selective case studies regarding this work, a review of all his operations for acromegaly during his early years has never been reported. We uncovered 37 patients who Cushing treated with surgical intervention directed at the pituitary gland. Of these, nine patients who presented with symptoms of acromegaly, and one with symptoms of gigantism were selected for further review. Two patients underwent transfrontal 'omega incision' approaches, and the remaining eight underwent transsphenoidal approaches. Of the 10 patients, 6 were male. The mean age was 38.0 years. The mean hospital stay was 39.4 days. There was one inpatient death during primary interventions (10%) and three patients were deceased at the time of last follow-up (33%). The mean time to death, calculated from the date of the primary surgical intervention, and including inpatient and outpatient deaths, was 11.3 months. The mean time to last follow-up, calculated from the day of discharge, was 59.3 months. At the time of last follow-up, two patients reported resolution of headache; four patients reported continued visual deficits, and two patients reported ongoing changes in mental status. This review analyzes the outcomes for 10 patients who underwent surgical intervention for acromegaly or gigantism, and offers an explanation for Cushing's transition from the transfrontal "omega incision" to the transsphenoidal approach while practicing at the Johns Hopkins Hospital.

Perioperative interruptions generated electronically from anaesthesia information management systems (AIMS) can provide useful feedback, but may adversely affect task performance if distractions occur at inopportune moments. Ideally such interruptions would occur only at times when their impact would be minimal. In this study of AIMS data, we evaluated the times of comments, drugs, fluids and periodic assessments (e.g. electrocardiogram diagnosis and train-of-four) to develop recommendations for the timing of interruptions during the intraoperative period. The 39,707 cases studied were divided into intervals between: 1) enter operating room; 2) induction; 3) intubation; 4) surgical incision; and 5) end surgery. Five-minute intervals of no documentation were determined for each case. The offsets from the start of each interval when >50% of ongoing cases had completed initial documentation were calculated (MIN50). The primary endpoint for each interval was the percentage of all cases still ongoing at MIN50. Results were that the intervals from entering the operating room to induction and from induction to intubation were unsuitable for interruptions confirming prior observational studies of anaesthesia workload. At least 13 minutes after surgical incision was the most suitable time for interruptions with 92% of cases still ongoing. Timing was minimally affected by the type of anaesthesia, surgical facility, surgical service, prone positioning or scheduled case duration. The implication of our results is that for mediated interruptions, waiting at least 13 minutes after the start of surgery is appropriate. Although we used AIMS data, operating room information system data is also suitable.

The purpose of this study is to describe an endoscope-assisted surgical technique for the excision of branchial cleft cysts and compare it to the standard approach. Retrospective case series review. Twenty-seven cases described as branchial cleft excisions performed by a single surgeon at one academic medical center were identified between 2007 and 2014. Twenty-five cases (8 endoscopic, 17 standard approach) were included in the study. Cases were excluded if final pathology was malignant. Patient charts were reviewed, and two techniques were compared through analysis of incision size, operative time, and surgical outcomes. This study showed that the length of incision required for the endoscopic approach (mean = 2.13 ± 0.23) was significantly less than that of the standard approach (mean = 4.10 ± 1.46, P = 0.008) despite the fact that there was no significant difference in cyst size between the two groups (P = 0.09). The other variables examined, including operative time and surgical outcomes, were not significantly different between the two groups. This transcervical endoscope-assisted approach to branchial cleft cyst excision is a viable option for uncomplicated cases. It provides better cosmetic results than the standard approach and does not negatively affect outcomes, increase operative time, or result in recurrence. 4.

Dual kidney transplantation (DKT) offers a safe way to face the organ shortage with good short-term and medium-term renal function. However, its application is limited by the longer operating time and the risk of surgical complication. This study reviews our results with DKT performed with an ipsilateral technique in terms of graft loss, graft and patient survival rates, and surgical complications. From January 2002 to March 2006, 23 patients underwent DKT through a monolateral Gibson incision with placement of both kidneys. One primary nonfunction occurred (4%). Delayed graft function was observed in 3 DKT (13.3%). Acute rejection rate was 4.3% (1 patient). All patients are alive at a mean follow-up of 28 months. One-year and 2-year graft survival rates were 100% and 96%, respectively. Mean serum creatinine level at 1-year posttransplantation was 1.3 mg/dL (range, 0.8-2.1 mg/dL). One DKG recipient lost 1 graft, retaining the second normal functioning graft due to ureteral necrosis. The mean hospital stay after transplantation was 15 days (range, 12-34 days). Monolateral placement in DKT offers the advantage of a single incision, minimizing the surgical risk. Tailored immunosuppression and careful selection of potential recipients, by excluding those with severe cardiopulmonary pathologies, could significantly improve both patient and graft survival in this group of patients.

Anxiety is an undesirable psychological phenomenon. Patients are usually anxious when subjected to third molar surgery, but the pattern of anxiety is unknown. The aim of this study was to assess the intensity and course of anxiety during third molar surgery. This study included 48 consecutive patients (mean age 25±6 years) who had a third molar removed surgically under local anaesthesia. The heart rate was monitored continuously during treatment as a measure of anxiety. Preoperative anxiety was scored with the Modified Dental Anxiety Scale. Each patient's anxiety level was assessed when in the waiting room, sitting down in the dental chair, during the application of local anaesthesia, application of surgical drapes, time-out procedure, incision, alveolotomy, removal of the third molar, and suturing, and at the end of the procedure. The lowest heart rates were recorded in the waiting room, in the dental chair, during anaesthesia, when applying surgical drapes, during suturing, and at the end of the procedure. The highest values were obtained during the time-out procedure, incision, and alveolotomy (P<0.005). In conclusion, the intensity and course of anxiety has a specific pattern during third molar surgery, with the lowest levels of anxiety prior to surgery and directly postoperative and the highest during the time-out procedure and the actual surgery.

The aim was to evaluate surgical techniques and their relationship to postoperative success rate and hearing outcomes in acquired atresia of the external auditory canal. In this article, 24 patients with acquired atresia of the external auditory canal were retrospectively evaluated regarding their canal status, hearing, and postoperative success. Acquired stenosis occurs more commonly in males with a male: female ratio of 2-3:1; it seems to be a disorder affecting young adults. Previous ear surgery (13 patients, 54.2%) and external ear trauma (11 patients, 45.8%) were the main etiological factors of acquired ear canal stenosis. Mastoidectomy (12/13) and traffic accidents (8/11) comprise the majority of these etiological factors. Endaural incision is performed in 79.2% and postauricular incision for 20.8% of cases during the operation. As types of surgical approach, transcanal (70.8%), transmastoid (20.8%), and combined (8.4%) approaches are chosen. The atretic plate is generally located at the bony-cartilaginous junction (37.5%) and in the cartilaginous canal (33.3%); the bony canal is involved in a few cases only. Preserved healthy canal skin, split- or full-thickness skin grafts, or pre- or postauricular skin flaps are used to line the ear canal, but preserved healthy canal skin is preferred. The results of surgery are generally satisfactory, and complications are few if surgical principles are followed.

Colorectal cancer is the fourth most diffuse cause of death in the world and local recurrence is associated with a reduced long-term life expectancy, with a reduced quality of life. Rectal washout at the anastomosis site leads to a statistically significant reduction of local recurrences. We developed the idea of a new laparoscopic stapler with an integrated washout system that could decontaminate the rectal stump before resection, without the need to enlarge the standard surgical incision or even to distort the incision site, closing the rectal stump just below the inferior part of the cancer, and then proceeding with the resection and stapling of the distal part of the tumor. Combined with these canonical functionalities, the new device, equipped with a patented washout system (patent number EP 3103401A1) will also allow to inject in the closed bowel a physiologic saline liquid. In force of the mechanical action of the liquid injected, carcinogenic exfoliated cells eventually floating in the affected region of the colonic lumen will be expelled through the anal orifice. The intraoperative rectal washout, both in minimally invasive and in traditional open surgery, thus becomes a simple, effective, and reproducible procedure. We describe the technical features and the possible clinical applications of a potentially new surgical laparoscopic stapler coupled with an integrated irrigation system. We have patented the system and we are developing a prototype with the aim to start an experimental pilot study.

Microvascular Decompression for Trigeminal Neuralgia: Technical Refinement for Complication Avoidance.

2016-10-01

Microvascular decompression (MVD) represents the most effective and safe surgical option for the treatment of trigeminal neuralgia since it was first popularized by Jannetta 50 years ago. Despite several advances, complications such as cerebellar and vascular injury, hearing loss, muscular atrophy, cerebrospinal fluid (CSF) leak, postoperative cutaneous pain, and sensory disturbances still occur and may negatively affect the outcome. We propose some technical nuances of the surgical procedure that were used in our recent series. We used a novel hockey stick-shaped retromastoid skin incision, preserving the major nerves of the occipital and temporal areas. Microsurgical steps were performed without the use of retractors. CSF leakage was prevented with a watertight dural closure and multilayer osteodural reconstruction. The refined surgical steps were perfected in the last consecutive 15 cases of our series. In these cases we did not record any cutaneous pain, sensory disturbances, or CSF leakage. The average diameter of the craniectomy was 18 mm. No patient reported major complications related to the intradural microsurgical maneuvers. In all cases the neurovascular conflict was found and solved with a good outcome in terms of pain disappearance. Our minimally invasive approach was demonstrated to guarantee an optimal exposure of the cerebellopontine angle and minimize the rate of complications related to skin incision and muscular dissection, microsurgical steps, and closure.

Liposarcoma is the single most common soft tissue sarcoma. Because mediastinal liposarcomas often grow rapidly and frequently recur locally despite adjuvant chemotherapy and radiotherapy, they require complete excision. Therefore, the feasibility of achieving complete surgical excision must be carefully considered. We here report a case of a huge mediastinal liposarcoma resected via clamshell thoracotomy. A 64-year-old man presented with dyspnea on effort. Cardiomegaly had been diagnosed 6 years previously, but had been left untreated. A computed tomography scan showed a huge (36 cm diameter) anterior mediastinal tumor expanding into the pleural cavities bilaterally. The tumor comprised mostly fatty tissue but contained two solid areas. Echo-guided needle biopsies were performed and a diagnosis of an atypical lipomatous tumor was established by pathological examination of the biopsy samples. Surgical resection was performed via a clamshell incision, enabling en bloc resection of this huge tumor. Although there was no invasion of surrounding organs, the left brachiocephalic vein was resected because it was circumferentially surrounded by tumor and could not be preserved. The tumor weighed 3500 g. Pathologic examination of the resected tumor resulted in a diagnosis of a biphasic tumor comprising dedifferentiated liposarcoma and non-adipocytic sarcoma with necrotic areas. The patient remains free of recurrent tumor 20 months postoperatively. Clamshell incision provides an excellent surgical field and can be performed safely in patients with huge mediastinal liposarcomas.

We are evaluating the technical feasibility of robotic-assisted laparoscopic vertical-intermediate platysmaplasty in conjunction with an open rhytidectomy. In a cadaveric study, the da Vinci Surgical System was used to access certain angles in the lower neck that are difficult for traditional short incision, short flap procedures. Ergonomics, approach, and technical challenges were noted. To date, there are no published reports of robotic-assisted neck lifts, motivating us to assess its potential in this field of plastic surgery. Standard open technique short flap rhytidectomies with concurrent experimental robotic-assisted platysmaplasties (neck lifts) were performed on six cadavers with the da Vinci Si Surgical System(®) (Intuitive Surgical, Sunnyvale, CA, USA). The surgical procedures were performed on a diverse cadaver population from June 2011 to January 2012. The procedures included (1) submental incision and laser-assisted liposuction, (2) open rhytidectomy, and (3) robotic-assisted platysmaplasty using knot-free sutures. A variety of sutures and fat extraction techniques, coupled with 0° and 30° three-dimensional endoscopes, were utilized to optimize visualization of the platysma. An unaltered da Vinci Si Surgical System with currently available instruments was easily adaptable to neck lift surgery. Mid-neck platysma exposure was excellent, tissue handling was delicate and precise, and suturing was easily performed. Robotic-assisted surgery has the potential to improve outcomes in neck lifts by offering the ability to manipulate instruments with increased freedom of movement, scaled motion, tremor reduction, and stereoscopic three-dimensional visualization in the deep neck. Future clinical studies on live human patients can better assess subject and surgeon benefits arising from the use of the da Vinci system for neck lifts. Evidence obtained from multiple time series with or without the intervention, such as case studies. Dramatic results in uncontrolled trials might also be regarded as this type of evidence.

To investigate the surgical outcomes, urinary incontinence and quality of life (QOL) of patients with pelvic organ prolapse after synthetic mesh-augmented repair in the Chinese population. This is a retrospective study of women who underwent synthetic mesh-augmented repair. Surgical outcomes were investigated by recurrence rate of prolapse and Organ Prolapse Quantification, and QOL by Pelvic Floor Impact Questionnaire-7 (PFIQ-7) and Pelvic Floor Distress Inventory-20 (PFDI-20). The sex life quality was evaluated by Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire-31 (PISQ-31). Eighty-three patients completed the entire study. Anatomical success was 90.36%. Of patients with preoperative stress urinary incontinence, 91.89% claimed that the incontinence symptoms were completely relieved. The 6-month PFDI-20 and PFIQ-7 scores were significantly decreased, indicating that improved QOL occurs. However, the PISQ-31 showed no significant difference between preoperative and postoperative data in sex life quality. The synthetic polypropylene mesh is effective in treating POP and may improve QOL with no significant difference in the sexual life postoperatively. De novo stress urinary incontinence may occur after synthetic mesh-augmented repair. © 2013 The Authors.

Outcome measures The WHO Situational Analysis Tool to Assess Emergency and Essential Surgical Care (WHO-SAT) was used to measure each participating facility's capacity to deliver essential surgery and anaesthesia services, including 108 items related to relevant infrastructure, human resources, interventions and equipment. Results While major surgical procedures were provided at each hospital, fewer than 30% had uninterrupted access to oxygen, and 57% had uninterrupted access to resuscitation bag and mask. Most hospitals reported capacity to provide general anaesthesia, though few hospitals reported having at least one certified surgeon, obstetrician and anaesthesiologist. Access to anaesthetic machines, pulse oximetry and blood bank was severely limited. Many non-hospital health centres providing basic surgical procedures, but almost none had uninterrupted access to electricity, running water, oxygen and basic supplies for resuscitation, airway management and obstetric services. Conclusions Capacity for essential surgery and anaesthesia services is severely limited in PNG due to shortfalls in physical infrastructure, human resources, and basic equipment and supplies. Achieving post-2015 sustainable development goals, including universal healthcare, will require significant investment in surgery and anaesthesia capacity in PNG. PMID:26674504

To evaluate visual outcomes and complications after phacoemulsification in eyes with cataract and previous radial keratotomy (RK) cuts using different sizes of clear corneal incisions. The study was a retrospective study. Thirty eyes with cataract and previous RK underwent phacoemulsification and intraocular lens (IOL) implantation. Among them 7 eyes had 8 RK cuts, 13 eyes had 12 RK cuts, and 10 eyes had 16 RK cuts. Phacoemulsification and IOL implantation were performed through a 2.0-3.2 mm clear corneal incision by a single surgeon. In the 8 RK cuts group, 3.2 mm clear corneal incisions were used in 4 eyes, and 3.0 mm clear corneal incisions were used in 3 eyes. In the 12 RK cuts group, 3.2 mm clear corneal incisions were used in 6 eyes, and 2.2 mm clear corneal incisions were used in 7 eyes. In the 16 RK cuts group, 3.2 mm clear corneal incisions were used in 5 eyes, and 2.0 mm clear corneal incisions were used in 5 eyes. Patients were followed up 1 day, 1 week, 1 month, 3 months, 6 months, 1 year, 2 years, and 3 years postoperatively and were examined for the dehiscence of RK cuts during or after the surgery, post-operative best-corrected visual acuity (BCVA), corneal astigmatism, corneal endothelial cell density and complications. Successful phacoemulsification with IOL implantation was performed in all eyes. No wound dehiscence was noted in any eyes with 8 or 12 RK cuts. Wound dehiscence was noted in 2 eyes with 16 RK cuts. The dehiscence of RK cuts was closed successfully by injecting an air bubble with or without viscoelastic agent into the anterior chamber at the end of surgery. During the follow-up, the cuts were well apposed in all eyes, and no new dehiscence of RK cuts was noted. At the last follow-up, mean BCVA (0.2 ± 0.18 logMAR) was better than preoperative BCVA(0.45±0.19 logMAR) (P < 0.001). There was no significant difference between the long-term preoperative and postoperative mean corneal astigmatism (P = 0.3). However, there was a significant reduction in postoperative corneal endothelial cell density (1866.5±773.9 / mm2 vs 2421.7±655.7 / mm2) (P < 0.001). Phacoemulsification and IOL implantation with clear corneal incisions in eyes with previous RK were associated with good surgical outcomes. Wound dehiscence was not specificaly related to the size of clear corneal incision during phacoemulsification in these eyes.

A facial sebaceous cyst is a common benign epithelial tumor and surgical excision is frequently performed but may cause obvious scarring and may be esthetically troubling. This study evaluated the clinical outcomes of the patients with facial sebaceous cyst enucleated by creating minimal elliptical incisions through a keratin-filled orifice. Eleven patients with facial sebaceous cyst enucleated by creating minimal elliptical incisions through a keratin-filled orifice. We treated nine male and two female patients aged 25-52 years. The mean cyst size was 1.85 × 1.56 cm. All cysts were successfully enucleated. The mean wound length was 0.93 cm. The mean operative time was 15.2 min. The mean follow-up duration was 41.5 months. No recurrence was noted, and all patients were very satisfied with their esthetic outcomes. All cysts were successfully enucleated. The mean elliptical wound length was 0.93 cm (range, 0.8-1.1 cm). The mean operative time was 15.2 min. We found no evidence of wound infection, or nerve or vascular injury. Enucleation of facial sebaceous cyst via a minimal elliptical incision through the keratin-filled orifice was associated with high-level patient satisfaction, and the method is safe and useful for treating facial epidermoid cysts. © 2016 Wiley Periodicals, Inc.

Our objective was to investigate whether High-Intensity Focused Ultrasound (HIFU) hemostasis can be achieved faster in the presence of ultrasound contrast agents (UCA). Incisions (3 cm long and 0.5 cm deep) were made in surgically exposed rabbit liver. Optison at a concentration of 0.18 ml/kg was injected into the mesenteric vein, immediately before the incision was made. The HIFU applicator (frequency of 5.5 MHz, and intensity of 3,700 W/cm2) was scanned manually over the incision (at an approximate rate of 1 mm/s) until hemostasis was achieved. The times to complete hemostasis were measured and normalized with the initial blood loss. The hemostasis times were 59±23 s in the presence of Optison and 70±23 s without Optison. The presence of Optison produced a 37% reduction in the normalized hemostasis times (p<0.05). Optison also provided faster (by 34%) formation of the coagulum seal over the lesion. Gross observations showed that the lesion size did not change due to the presence of Optison. Histological analysis showed that lesions consisted of an area of coagulation necrosis in vicinity of the incision, occasionally surrounded by a congestion zone filled with blood. Our results suggest the potential utility of microbubble contrast agents for increasing efficiency of HIFU hemostasis of internal organ injuries.

The improvement of antibiotic rational use in China was studied by usage analysis of combination antibiotic therapy for type I incisions in 244 hospitals. Five kinds of hospitals, including general hospital, maternity hospital, children's hospital, stomatological hospital and cancer hospital, from 30 provinces were surveyed. A systematic random sampling strategy was employed to select outpatient prescriptions and inpatient cases in 2011 and 2012. A total of 29 280 outpatient prescriptions and 73 200 inpatient cases from 244 hospitals in each year were analyzed. Data were collected with regards to the implementation of the national antibiotic stewardship program (NASP), the overall usage and the prophylactic use of antibiotic for type I incisions. Univariate analysis was used for microbiological diagnosis rate before antimicrobial therapy, prophylactic use of antibiotics for type I incision operation, and so on. For multivariate analysis, the use of antibiotics was dichotomized according to the guidelines, and entered as binary values into logistic regression analysis. The results were compared with the corresponding criteria given by the guidelines of this campaign. The antibiotic stewardship in China was effective in that more than 80% of each kind of hospitals achieved the criteria of recommended antibiotics varieties. Hospital type appeared to be a factor statistically associated with stewardship outcome. The prophylactic use of antibiotics on type I incision operations decreased by 16.22% (P<0.05). The usage of combination antibiotic therapy for type I incisions was also decreased. Region and bed size were the main determinants on surgical prophylaxis for type I incision. This national analysis of hospitals on antibiotic use and stewardship allows relevant comparisons for bench marking. More efforts addressing the root cause of antibiotics abuse would continue to improve the rational use of antibiotics in China.

The left wing of a whooping crane (Grus americana) was amputated for treatment of severe nonunion and malunion fractures of the radius and ulna. During the postoperative convalescent period, the bird aspirated a corn kernel and subsequently suffered episodic bouts of dyspnea. The bird was anesthetized with tiletamine-zolazepam. Attempts to deliver the kernel through the glottis with endoscopic instruments were unsuccessful. The corn kernel was retrieved via a tracheotomy incision. Endoscopy of the trachea 2 mo postoperatively showed complete healing of the tracheal incision. Mucosal integrity had been reestablished, and tracheal lumen diameter was not compromised. The bird continues in good health 2.5 yr after surgery, shows no sign of respiratory disease, and currently is in a captive breeding program.

Abstract Objectives To explore the effects of the students' gender on their perception of quality and quantity of teaching, the amount of experiential learning, and their interest in obstetrics and gynecology. Methods Anonymous, self-administered surveys to third-year medical students rotating on the obstetrics and gynecology clerkship. Results Eighty-one of 91 students participated (89% response rate): 33 men, 46 women, 2 declined to reveal their gender. No significant gender differences existed regarding number of interactions with residents and faculty; number of deliveries, surgeries, or examinations performed; perceived quality of teaching; or feeling included as part of the clinical team. Male students were more likely to report performing specific surgical procedures, such as operating the bovie cautery during gynecological surgeries (p = 0.005). More men experienced patients refusing to allow them to participate in the clinical interview (p < 0.0001) and physical examination (p < 0.0001). Male students were also more likely to report feeling that their gender negatively impacted their clerkship experience (p < 0.0001). Although less likely to report preclerkship and postclerkship career interest in obstetrics and gynecology, male students were more likely to report that their interest increased at the end of the clerkship. Conclusions Male students were more likely to experience gender bias from patients on the obstetrics and gynecology service. Male students also described feeling socially excluded from female-dominated clinical teams. Obstetrics and gynecology educators need to consider methods of encouraging patients to accept medical student participation regardless of gender. Obstetrics and gynecology faculty and residents need to be sensitive to subtle forms of gender bias and ensure equal inclusion for both male and female medical students. PMID:20088663

Most intrathoracic goiters are located in the anterior mediastinum. Surgical resection is usually recommended in case of morbidity associated with the goiter’s mass effect or for suspicion of malignancy difficult to diagnose without resection. Intrathoracic goiters are usually resected through a cervical approach, with sternotomy needed in selected cases. We report a case of antero mediastinal retrosternal goiter in old age patient undergoing surgical excision by combined cervical and hybrid robot-assisted approach. All steps of the thoracic procedure were completely performed using the da Vinci robot system with final extension of a port-site incision to extract the specimen. This approach provides more advantages than sternotomy regarding post operative clinical benefits and allows a more accurate surgical resection in the antero-superior mediastinum than conventional thoracoscopy.

Using a 445-nm semiconductor laser for tissue incision, an effective cut is expected due to the special absorption properties of blue laser light in soft tissues. The aim of the present study was the histological evaluation of tissue samples after incision with a 445-nm diode laser. Forty soft tissue specimens were obtained from pork oral mucosa and mounted on a motorized linear translation stage. The handpiece of a high-frequency surgery device, a 970-nm semiconductor laser, and a 445-nm semiconductor laser were connected to the slide, allowing a constant linear movement (2 mm/s) and the same distance of the working tip to the soft tissue's surface. Four incisions were made each: (I) 970-nm laser with conditioned fiber tip, contact mode at 3-W cw; (II-III): 445-nm laser with non-conditioned fiber tip, contact mode at 2-W cw, and non-contact mode (1 mm) at 2 W; and (IV): high-frequency surgery device with straight working tip, 90° angulation, contact mode at 50 W. Histological analysis was performed after H&E staining of the embedded specimens at 35-fold magnification. The comparison of the incision depths showed a significant difference depending on the laser wavelength and the selected laser parameters. The highest incision depth was achieved with the 445-nm laser contact mode (median depth 0.61 mm, min 0.26, max 1.17, interquartile range 0.58) (p < 0.05) with the lowest amount of soft tissue denaturation (p < 0.05). The lowest incision depth was measured for the high-frequency surgical device (median depth 0.36 mm, min 0.12, max 1.12, interquartile range 0.23) (p < 0.05). Using a 445-nm semiconductor laser, a higher cutting efficiency can be expected when compared with a 970-nm diode laser and high-frequency surgery. Even the 445-nm laser application in non-contact mode shows clinically acceptable incision depths without signs of extensive soft tissue denaturation.

Caesarean section (CS) results in the occurrence of the phenomenon 'niche'. A 'niche' describes the presence of a hypoechoic area within the myometrium of the lower uterine segment, reflecting a discontinuation of the myometrium at the site of a previous CS. Using gel or saline instillation sonohysterography, a niche is identified in the scar in more than half of the women who had had a CS, most with the uterus closed in one single layer, without closure of the peritoneum. An incompletely healed scar is a long-term complication of the CS and is associated with more gynaecological symptoms than is commonly acknowledged. Approximately 30% of women with a niche report spotting at 6-12 months after their CS. Other reported symptoms in women with a niche are dysmenorrhoea, chronic pelvic pain and dyspareunia. Given the association between a niche and gynaecological symptoms, obstetric complications and potentially with subfertility, it is important to elucidate the aetiology of niche development after CS in order to develop preventive strategies. Based on current published data and our observations during sonographic, hysteroscopic and laparoscopic evaluations of niches we postulate some hypotheses on niche development. Possible factors that could play a role in niche development include a very low incision through cervical tissue, inadequate suturing technique during closure of the uterine scar, surgical interventions that increase adhesion formation or patient-related factors that impair wound healing or increase inflammation or adhesion formation. © The Author 2015.

Objectives The goal of this study was to define the radiologic characteristics of two-phase computed tomography (CT) of salivary gland Warthin tumors and to compare them to pleomorphic adenomas. We also aimed to provide a foundation for selecting a surgical method on the basis of radiologic findings. Methods We prospectively enrolled 116 patients with parotid gland tumors, who underwent two-phase CT preoperatively. Early and delayed phase scans were obtained, with scanning delays of 30 and 120 seconds, respectively. The attenuation changes and enhancement patterns were analyzed. In cases when the attenuation changes were decreased, we presumed Warthin tumor preoperatively and performed extracapsular dissection. When the attenuation changes were increased, superficial parotidectomy was performed on the parotid gland tumors. We analyzed the operation times, incision sizes, complications, and recurrence rates. Results Attenuation of Warthin tumors was decreased from early to delayed scans. The ratio of CT numbers in Warthin tumors was also significantly different from other tumors. Warthin tumors were diagnosed with a sensitivity of 96.1% and specificity of 97% using two-phase CT. The mean operation time was 38 minutes and the mean incision size was 36.2 mm for Warthin tumors. However, for the other parotid tumors, the average operation time was 122 minutes and the average incision size was 91.8 mm (P<0.05). Conclusion Salivary Warthin tumor has a distinct pattern of contrast enhancement on two-phase CT, which can guide treatment decisions. The preoperative diagnosis of Warthin tumor made extracapsular dissection possible instead of superficial parotidectomy. PMID:25177439

Laparoscopic bariatric surgery has experienced a rapid expansion of interest over the past 5 years, with a 470% increase. This rapid expansion has markedly increased overall cost, reducing surgical access. Many surgeons believe that the traditional open approach is a cheaper, safer, equally effective alternative. 16 highly experienced "open" bariatric surgeons with a combined total of 25,759 cases representing >200 surgeon years of experience, pooled their open Roux-en-Y gastric bypass (ORYGBP) data, and compared their results to the leading laparoscopic (LRYGBP) papers in the literature. In the overall series, the incisional hernia rate was 6.4% using the standard midline incision. Utilizing the left subcostal incision (LSI), it was only 0.3%. Return to surgery in <30 days was 0.7%, deaths 0.25%, and leaks 0.4%. Average length of stay was 3.4 days, and return to usual activity 21 days. Small bowel obstruction was significantly higher with the LRYGBP. Surgical equipment costs averaged approximately $3,000 less for "open" cases. LRYGBP had an added expense for longer operative time. This more than made up for the shorter length of stay with the laparoscopic approach. The higher cost, higher leak rate, higher rate of small bowel obstruction, and similar long-term weight loss results make the "open" RYGBP our preferred operation. If the incision is taken out of the equation (i.e. use of the LSI), the significant advantages of the open technique become even more obvious.

Systemic antibiotic prophylaxis prior to gastrointestinal surgery - is oral administration of doxycycline and metronidazole adequate?

Antibiotic prophylaxis is recommended prior to a wide range of gastrointestinal operations to reduce the rate of surgical site infections (SSIs). Traditional intravenous (IV) drugs are costly and their preparation strains nursing resources at the wards. While oral administration may attenuate these limitations, its use remains limited. We aimed to assess whether a dual oral antibiotic prophylaxis regimen provides adequate serum concentrations throughout the surgical procedure. We measured serum concentrations of doxycycline and metronidazole following single oral doses of 400 mg doxycycline and 1200 mg metronidazole at first incision and repeated at wound closure in a cohort of patients undergoing elective gastrointestinal surgery. Both drugs were dispensed at least two hours before skin incision. Serum concentrations were compared to minimum inhibitory concentrations (MIC) and epidemiological cut-off values (ECOFFs) for relevant pathogens. Mean serum concentrations of doxycycline at first incision and at wound closure were 5.75 mg/L and 4.66 mg/L and of metronidazole 18.88 mg/L and 15.56 mg/L, respectively. Metronidazole concentrations were above ECOFF (2 mg/L) for relevant anaerobic species in 103/104 of patients in both samples. Doxycycline serum concentrations were above the ECOFF for common Enterobacteriaceae species (4 mg/L) in both samples in 58/104 patients (55.8%). A single dose of orally administered metronidazole provides adequate concentrations throughout surgery in a heterogeneous cohort of patients. Uncertainty persists regarding the adequacy of doxycycline concentrations, as the optimal serum level of doxycycline in a prophylactic setting has not been established.

Minimalist breast conserving surgical approaches for inferiorly sited cancers

PubMed Central

2017-01-01

Contemporary data suggests that breast conservation treatment (BCT) may confer a survival advantage when compared to mastectomy. Hence, it would be logical to adopt strategies which increase eligibility of successful BCT without compromising oncologic principles or cosmetic outcome. With respect to achieving good aesthetics, inferiorly sited breast cancers pose a particular technical challenge. A vast array of techniques, collectively referred to as oncoplastic breast surgery (OBS) have been developed to minimise post treatment distortion. The purported advantages of these approaches are the acquisition of wider margins and reduced re-excision rates. However, to date, there is a lack of data demonstrating significant reduction in local recurrence and overall survival when compared with less extensive procedures. In this review, “minimalist” procedures are described where strict oncologic criteria of clear margins are fulfilled and acceptable cosmesis are simultaneously achieved. These techniques offer less tissue loss, less extensive parenchymal mobilisation and shorter operating times without compromising margin status and aesthetics. They involve the combination of innovative incision designs and certain parenchymal resection patterns. Incision designs include the boomerang, golf-tee, anchor and arrowhead incisions which have been previously described but not widely used. Parenchymal resection patterns follow the “sick lobe hypothesis”. These techniques, termed “reductionist”, or “minimalist” comprising approaches where breast conserving surgery is condensed to its irreducible elements, offer alternatives which align with contemporary objectives of surgery where optimal survival outcomes are achieved through individualised procedures resulting in reduced iatrogenic impact. This logically allows scope for de-escalation of surgical therapy for breast cancer. PMID:28861382

Abstract Background: Surgical site infections (SSI) account for a major proportion of hospital-acquired infections. They are associated with longer hospital stay, readmissions, increased costs, mortality, and morbidity. Reducing SSI is a goal of the Surgical Care Improvement Project and identifying interventions that reduce SSI effectively is of interest. In a single-blinded randomized controlled trial (RCT) we evaluated the effect of localized warming applied to surgical incisions on SSI development and selected cellular (immune, endothelial) and tissue responses (oxygenation, collagen). Methods: After Institutional Review Board approval and consent, patients having open bariatric, colon, or gynecologic-oncologic related operations were enrolled and randomly assigned to local incision warming (6 post-operative treatments) or non-warming. A prototype surgical bandage was used for all patients. The study protocol included intra-operative warming to maintain core temperature ≥36°C and administration of 0.80 FIO2. Patients were followed for 6 wks for the primary outcome of SSI determined by U.S. Centers for Disease Control (CDC) criteria and ASEPSIS scores (additional treatment; presence of serous discharge, erythema, purulent exudate, and separation of the deep tissues; isolation of bacteria; and duration of inpatient stay). Tissue oxygen (PscO2) and samples for cellular analyses were obtained using subcutaneous polytetrafluoroethylene (ePTFE) tubes and oxygen micro-electrodes implanted adjacent to the incision. Cellular and tissue ePTFE samples were evaluated using flow cytometry, immunohistochemistry, and Sircol™ collagen assay (Biocolor Ltd., Carrickfergus, United Kingdom). Results: One hundred forty-six patients participated (n=73 per group). Study groups were similar on demographic parameters and for intra-operative management factors. The CDC defined rate of SSI was 18%; occurrence of SSI between groups did not differ (p=0.27). At 2 wks, warmed patients had better ASEPSIS scores (p=0.04) but this difference was not observed at 6 wks. There were no significant differences in immune, endothelial cell, or collagen responses between groups. On post-operative days one to two, warmed patients had greater PscO2 change scores with an average PscO2 increase of 9–10 mm Hg above baseline (p<0.04). Conclusions: Post-operative local warming compared with non-warming followed in this study, which included intra-operative warming to maintain normothermia and FIO2 level of 0.80, did not reduce SSI and had no effect on immune, endothelial cell presence, or collagen synthesis. PscO2 increased significantly with warming, however, the increase was modest and less than expected or what has been observed in studies testing other interventions. PMID:26125454

Two cases of hypopharyngeal cyst are reported. Both cysts occurred in the piriform sinus of the hypopharynx. Histopathological examination indicated that both were retention cysts. These cysts were removed by laryngomicrosurgical technique using a side-opened direct laryngoscope. In the cyst with a distinct base, a laryngomicrosurgical snare was used for removal. In the wide-based cyst, the mucous membrane around the cyst was incised with an electrosurgical instrument and then detached to facilitate removal. In this paper, we describe our surgical procedure for removing hypopharyngeal cysts and discuss the causes of such cysts.

Offering real-time, high-resolution images via intraoperative ultrasound is advantageous for a variety of peripheral nerve applications. To highlight the advantages of ultrasound, its extraoperative uses are reviewed. The current intraoperative uses, including nerve localization, real-time evaluation of peripheral nerve tumors, and implantation of leads for peripheral nerve stimulation, are reviewed. Although intraoperative peripheral nerve localization has been performed previously using guide wires and surgical dyes, the authors' approach using ultrasound-guided instrument clamps helps guide surgical dissection to the target nerve, which could lead to more timely operations and shorter incisions.

To present clinical cases examining the effectiveness and safety of pelvic packing with vaginal traction for inhibiting obstetric hemorrhage among women receiving treatment at a public obstetrics and gynecology tertiary care hospital in Mexico. In a retrospective observational descriptive study, eight cases of obstetric hemorrhage treated by pelvic packing with vaginal traction between January 2012 and December 2013 at Hospital de la Mujer, Mexico City, Mexico, were reviewed. The mean patient age was 28.8±6.8 years. The average blood loss was 4535±897 mL. Uterine atony was the cause of bleeding among six patients: histopathologic examination revealed two cases of placenta accreta, one case of placenta percreta, two cases of uteroplacental apoplexy, and one case of myomatosis. For two patients, placental separation was difficult and required surgical management. The packing technique was effective for all patients. No patients presented with infection or required re-operation for bleeding management. No deaths occurred. For management of bleeding among patients with underlying coagulation disorders, pelvic packing can be useful when standard techniques such as hysterectomy, tubal hypogastric ligation, and/or pharmacologic therapy are unsuccessful.
