    Analysis of the surgical criteria for reintervention in Abdominal Surgery led to the accentuation of a certain number of pictures of occlusion, general infectious syndromes, postoperative peritonitis, gastro-intestinal fistula and hemorrhagic syndrome. In all cases, the clinical examination can be misleading in particular in the case of peritonitis, and the history and non-surgical criteria must be strongly borne in mind. PMID:2036

    Significant advances in veterinary diagnostic and surgical techniques have been made over the past several decades. Many of these advances, however, have not reached the field of marine mammal medicine. A number of limitations exist: risks of anesthesia, anatomical challenges, difficulties with wound closure, environmental constraints, equipment limitations, and perceived risks. Despite these limitations, surgical treatments have been successfully utilized in marine mammals. While surgery is performed in pinnipeds more frequently than in cetaceans, studies conducted in the 1960s and 1970s on dolphin sleep and hearing demonstrated that general anesthesia can be successfully induced in cetaceans. Since this pioneering work, a small number of successful surgeries have been performed in dolphins under both general anesthesia and heavy sedation. While these surgical procedures in pinnipeds and cetaceans have typically been limited to wound management, dentistry, ophthalmic procedures, fracture repair, and superficial biopsy, a number of abdominal surgeries have also been performed. Recently there have been pioneering successes in the application of minimally invasive surgery in marine mammals. Many of the anatomical challenges that almost prohibit traditional laparotomies in cetacean species and present challenges in pinnipeds can be overcome through the use of laparoscopic techniques. Due to the limited number of pinnipeds and cetaceans in captivity and, thus, the limited case load for veterinarians serving marine mammal species, it is vital for knowledge of surgical procedures to be shared among those in the field. This paper reviews case reports of surgical procedures, both traditional and laparoscopic, in pinnipeds and cetaceans. Limitations to performing surgical procedures in marine mammals are discussed and surgical case reports analyzed in an effort to determine challenges that must be overcome in order to make surgery a more feasible diagnostic and treatment

    Surgical procedures for voice restoration serve to improve oral communication by better vocal function. They comprise of phonomicrosurgery, with direct and indirect access to the larynx; laryngoplasty; laryngeal injections; and surgical laryngeal reinnervation. The basis for modern surgical techniques for voice disorders is the knowledge about the ultrastructure of the vocal folds and the increasing experience of surgeons in voice surgery, while facing high social and professional demands on the voice. Vocal activity limitation and participation restriction has become more important in the artistic and social areas. A number of surgical methods that have been developed worldwide for this reason, are presented in this article. Functional oriented surgery has to meet high standards. The diagnostics of vocal function has to be multi-dimensional in order to determine the indication and the appropriate surgical intervention. PMID:22073062

    To carry out an abdominal ultrasound examination with the highest degree of accuracy and thoroughness, it is essential to have a good knowledge of the anatomy and the normal measurements of the different organs. In this way, we can determine their normal condition and identify the pathology and its location more easily. It is very important to adopt a correct examination procedure, systematically sweeping the scan in the same direction and not leaving any organ unexamined. We suggest a procedure consisting of longitudinal, cross-sectional and oblique scans to view all the abdominal organs, starting the examination in the epigastric region, scanning first the right upper quadrant, then the left upper quadrant, both iliac fossa, and lastly the hypogastric region.

    Obesity is a risk factor for surgical site infection (SSI) after abdominal procedures; however, data characterizing the risk of SSI in obese patients during abdominal procedures are lacking. We hypothesized that obesity is an independent risk factor for SSI across wound classes. We analyzed American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) data for 2011. We calculated body mass index (BMI), classifying patients according to National Institute of Health (NIH) BMI groups. We excluded records in which height/weight was not recorded and patients with BMI less than 18.5. We examined patients undergoing open abdominal procedures, performing univariate and multivariate analyses to assess the relative contribution of obesity to SSI. Study criteria were met by 89,148 patients. Obese and morbidly obese patients had significantly greater SSI rates in clean and clean-contaminated cases but not contaminated or dirty/infected cases. Logistic regression confirmed obesity and morbid obesity as being independently associated with the overall SSI development, specifically in clean [Obesity odds ratio (OR) = 1.757, morbid obesity OR = 2.544, P < 0.001] and clean-contaminated (obesity OR = 1.239, morbid obesity OR = 1.287, P < 0.001) cases. Obesity is associated with increased risk of SSI overall, specifically in clean and clean-contaminated abdominal procedures; this is independent of diabetes mellitus. Novel techniques are needed to reduce SSI in this high-risk patient population. PMID:27097626

    During 2011 - 2014 yrs in Surgical Clinic of The First City Clinic (Poltava) a relaparotomy was performed in 127 patients. There was established, that relaparotomy constitutes the only one procedure for such life threatening states, as intraabdominal bleeding, ileus in a decompensation stage, eventration, progressing peritonitis, abdominal compartment syndrome stages III - IV. The rate of relaparotomy application after performance of urgent operative interventions is bigger than after planned operations (ratio 4:1). Individual estimation of a state and choice of optimal surgical tactics during primary and secondary operative interventions are needed to improve the results of treatment. PMID:26946667

    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.

  9. A new technique for surgical treatment of vaginal agenesis using combined abdominal-perineal approach.

    Optimum therapeutic approach in vaginal agenesis has always been an area of extensive controversies. Although surgical management gained priority due to the evolution of techniques, there is currently no consensus in the literature regarding the best type of surgical approach. The most commonly preferred surgical procedure among gynecologists is McIndoe operation which involves the creation of a space between bladder and rectum, insertion of a mold covered with split-thickness skin graft into that neovaginal space, and use of postoperative vaginal dilation to avoid stenosis. However, many modifications have been introduced in time in an attempt to increase the success rates. In this paper, we describe two cases with vaginal agenesis with functioning uterus who were subjected to surgery by combined abdominal-perineal approach. The surgical technique also included the use of a specially designed vaginal mold made up of polymethyl methacrylate and use of Hyalobarrier gel which is an adhesion-preventing agent. PMID:21577259

    1988-01-01

    Since 1888 98 papers have been presented to the Southern Surgical Association (SSA) dealing directly or indirectly with abdominal trauma. The papers reflect the progress over the century in the management of this injury. Almost two-thirds of the papers have originated from the major city hospitals of the south. An interest in abdominal trauma has been manifest among the officers of SSA. Twenty-two presidents have presented papers or taken part in discussions. Four 25-year eras were identified. In the earliest, exploration of abdominal wounds was firmly established as a principle. The second period was characterized by consolidation of principles and strengthening of supportive care. The third era encompassing World War II marked a nadir in productivity. In the last 25 years a reawakened interest has resulted in a marked increase in the number and quality of presentations, which have increasingly focused on specific organ injuries. Images Fig. 1.

    Trigeminal neuralgia is a type of facial pain that is difficult to treat. The pain can be excruciating and debilitating. The wide range of treatments currently used for trigeminal neuralgia is ample evidence that there is no simple answer to how it should be managed. This review will evaluate the current surgical procedures used for the treatment of trigeminal neuralgia. A critical analysis of the evidence-based studies to date was done to evaluate and compare the efficacy of the different surgical procedures. Arguments for and against the use of surgery for trigeminal neuralgia are presented. In addition, the surgical procedures were compared with other treatments for trigeminal neuralgia. PMID:14959906

    Small mammal surgical procedures are a part of clinical veterinary practice and are performed with regularity. Anesthetic and analgesic techniques are important components of any successful small mammal surgical procedure. Many basic surgical principles used in dogs and cats can be directly applied to small mammals, but tissues tend to be smaller and thinner, and hemostasis is critical with small patients due to risk of death with minimal blood loss. Common surgical procedures in small mammals include integumentary mass and abscess excision, reproductive procedures, gastrointestinal foreign body removal, urolith removal, prolapsed tissues associated with the gastrointestinal tract, intra-abdominal mass excision, and hepatic surgery.

    Between 1980 and 1992, 116 patients had either a simple mastectomy (32) or intra-abdominal procedures (84) under local anaesthesia (0.5-1% lignocaine with 1:200 000 adrenaline). A wide variety of general surgical procedures were feasible using only supplementary intravenous sedation (54%). Complications were uncommon and related to surgical procedure (three incorrect diagnoses, three procedures impossible) rather than the anaesthetic technique. There were no anaesthetic toxicity or postoperative problems. Local anaesthesia is extremely safe and facilitates larger surgical procedures than is generally appreciated. PMID:8871461

    Nineteen women who had an abdominal sacrocolpopexy (ASC) with synthetic mesh and 18 women who had an ASC with freeze-dried, irradiated cadaveric fascia lata returned for blinded pelvic organ prolapse quantification (POPQ) examinations. The mean relative vaginal descent (delta) from perfect total vaginal length in the mesh group was 1.1 (0.3) cm, and the delta in the fascia group was 2.8 (0.8) cm (p=0.02, Mann-Whitney U). The proportion of women with "optimal" surgical outcome in the mesh group was 89% and 61% in the fascia group (p=0.06, Fischer's exact test). This study suggests that cadaveric fascia lata may not be a good choice for ASC. PMID:15645147

    As a result of the trend toward late childbearing, fertility preservation has become a major issue in young women with gynaecological cancer. Fertility-sparing treatments have been successfully attempted in selected cases of cervical, endometrial and ovarian cancer, and gynaecologists should be familiar with fertility-preserving options in women with gynaecological malignancies. Options to preserve fertility include shielding to reduce radiation damage, fertility preservation when undergoing cytotoxic treatments, cryopreservation, assisted reproduction techniques, and fertility-sparing surgical procedures. Radical vaginal trachelectomy with laparoscopic lymphadenectomy is an oncologically safe, fertility-preserving procedure. It has been accepted worldwide as a surgical treatment of small early stage cervical cancers. Selected cases of early stage ovarian cancer can be treated by unilateral salpingo-ophorectomy and surgical staging. Hysteroscopic resection and progesterone treatment are used in young women who have endometrial cancer to maintain fertility and avoid surgical menopause. Appropriate patient selection, and careful oncologic, psychologic, reproductive and obstetric counselling, is mandatory. PMID:22503435

    In many surgeries, especially orthopedic procedures, power tools such as saws and drills are used. These tools may produce aerosolized blood and other biological material from bone and soft tissues. Surgical lasers and electrocautery tools can also produce aerosols when tissues are vaporized and condensed. Studies have been reported in the literature concerning production of aerosols during surgery, and some of these aerosols may contain infectious material. Garden et al. (1988) reported the presence of papilloma virus DNA in the fumes produced from laser surgery, but the infectivity of the aerosol was not assessed. Moon and Nininger (1989) measured the size distribution and production rate of emissions from laser surgery and found that particles were generally less than 0.5 {mu}m diameter. More recently there has been concern expressed over the production of aerosolized blood during surgical procedures that require power tools. In an in vitro study, the production of an aerosol containing the human immunodeficiency virus (HIV) was reported when power tools were used to cut tissues with blood infected with HIV. Another study measured the size distribution of blood aerosols produced by surgical power tools and found blood-containing particles in a number of size ranges. Health care workers are anxious and concerned about whether surgically produced aerosols are inspirable and can contain viable pathogens such as HIV. Other pathogens such as hepatitis B virus (HBV) are also of concern. The Occupational Safety and Health funded a project at the National Institute for Inhalation Toxicology Research Institute to assess the extent of aerosolization of blood and other tissues during surgical procedures. This document reports details of the experimental and sampling approach, methods, analyses, and results on potential production of blood-associated aerosols from surgical procedures in the laboratory and in the hospital surgical suite.

  18. Selected overview of nongynecologic surgical intra-abdominal infections. Prophylaxis and therapy.

    PubMed

    1985-11-29

    True prophylaxis of intra-abdominal nongynecologic infections is limited to elective, nonemergency surgery and is best shown in three clean-contaminated surgical procedures. All of these have an infection rate of approximately 10 to 20 percent and include all colon resection surgery, most gastric surgery, and about one third of the cholecystectomies for chronic calculous cholecystitis. Each of these three surgical procedures has a somewhat different pattern of bacterial pathogens. The most useful comparative studies of early preoperative therapy have been performed in cases of suspected appendicitis (50 percent of which usually show perforation or gangrene at the time of surgery) and penetrating abdominal wounds (80 percent of which usually enter some part of the bowel and theoretically soil the peritoneum). These procedures are usually classified as contaminated, with a 20 to 30 percent infection rate, or dirty, with a more than 30 percent infection rate, depending upon several factors. Comparative investigations of intraoperative and postoperative antibiotic therapy of established intra-abdominal infections are more difficult to obtain because of the heterogeneity of the sites, organisms, and medical and surgical therapy. The initial pathogens causing secondary peritonitis and hepatic, perirectal, diverticular, and most other types of intraperitoneal abscesses are mixed coliforms and anaerobes, with emphasis on the anaerobes. Retroperitoneal abscesses, pancreatic abscesses, and biliary tract infections are predominantly caused by coliforms. The organisms responsible for these early infections are usually community-acquired rather than more antibiotic-resistant hospital-acquired bacteria. Considering the availability of a large number of effective broad-spectrum antibacterial agents and therapeutic combinations, it has become increasingly difficult to assess the rightful place of any new prospective antimicrobial regimen unless it has quite unique characteristics

    This paper introduces a computer-based system that is designed to record a surgical procedure with multiple depth cameras and reconstruct in three dimensions the dynamic geometry of the actions and events that occur during the procedure. The resulting 3D-plus-time data takes the form of dynamic, textured geometry and can be immersively examined at a later time; equipped with a Virtual Reality headset such as Oculus Rift DK2, a user can walk around the reconstruction of the procedure room while controlling playback of the recorded surgical procedure with simple VCR-like controls (play, pause, rewind, fast forward). The reconstruction can be annotated in space and time to provide more information of the scene to users. We expect such a system to be useful in applications such as training of medical students and nurses. PMID:27046554

    One of the major challenges in the development of virtual environments for medical simulations is photorealistic rendering, permitting high fidelity visual effects and user interaction. Digitized videos recorded from the laparoscopic camera are a rich source of information about surgical scenarios. How to fully utilize the information is important for improving the realism of the simulated scenarios. In reality, the camera viewpoint changes frequently and even for the same viewpoint, the scene is dynamic due to rhythmic heartbeat. Hence, the results of classical texture mapping are usually visually unappealing as they fail to capture the pulsatile effect, as well as other global illumination properties of the scene. In this paper we present a hybrid technique to improve the photorealistic rendering of the virtual surgery scenarios by spatio-temporally utilizing videos recorded during actual surgical procedures.

    Introduction: We described a modified surgical procedure for repairing a concealed penis and compared the efficacy and feasibility of modified repair with traditional repair. Methods: From March 2003 to December 2012, 96 patients with a concealed penis were recruited to undergo penile repair at our centre. Modified repair and traditional repair were performed respectively on 46 and 50 cases. We compared operative time, intraoperative blood loss, cosmetic result of operative scars, postoperative penile retraction, and complications. Results: All operations were completed successfully without serious complications. The mean operative time, intraoperative blood loss, and cosmetic result of the operative scar between the two surgical methods were similar. However, the postoperative penile retraction rate in patients undergoing modified repair decreased significantly than in the traditional repair. Conclusions: Our modified surgical procedure is effective and feasible for a concealed penis. Although extra procedures were needed for the modified repair, the operative time, intraoperative blood loss and cosmetic result of operative scar between the two procedures were similar. Compared with traditional repair, modified repair has better clinical outcomes. PMID:26664507

    Objective: Previous abdominal wall surgery is viewed as a contraindication to abdominal free tissue transfer. We present two patients who underwent multiple abdominal liposuction procedures, followed by successful free deep inferior epigastric artery perforator flap. We review the literature pertaining to reliability of abdominal free flaps in those with previous abdominal surgery. Methods: Review of case notes and radiological investigations of two patients, and a PubMed search using the terms “DIEP”, “deep inferior epigastric”, “TRAM”, “transverse rectus abdominis”, “perforator” and “laparotomy”, “abdominal wall”, “liposuction”, “liposculpture”, “fat graft”, “pfannenstiel”, with subsequent appraisal of relevant papers by the first and second authors. Results: Patient 1 had 3 episodes of liposuction from the abdomen for fat grafting to a reconstructed breast. Subsequent revision reconstruction of the same breast with DIEP flap was preceded by CT angiography, which demonstrated normal perforator anatomy. The reconstruction healed well with no ischaemic complications. Patient 2 had 5 liposuction procedures from the abdomen to graft fat to a wide local excision defect. Recurrence of cancer led to mastectomy and immediate reconstruction with free DIEP flap. Preoperative MR angiography demonstrated a large perforator right of the umbilicus, with which the intraoperative findings were consistent. The patient had an uneventful recovery and good healing with no fat necrosis or wound dehiscence. Conclusions: We demonstrate that DIEP flaps can safely be raised without perfusion-related complications following multiple liposuction procedures to the abdomen. The safe interval between procedures is difficult to quantify, but we demonstrate successful free flap after 16 months. PMID:25671046

    A reliable means for measuring temperatures generated during surgical procedures is needed to recommend best practices for inserting fixation devices and minimizing the risk of osteonecrosis. Twenty four screw tests for three surgical procedures were conducted using the four thermocouples in the bone and one thermocouple in the screw. The maximum temperature rise recorded from the thermocouple in the screw (92.7±8.9°C, 158.7±20.9°C, 204.4±35.2°C) was consistently higher than the average temperature rise recorded in the bone (31.8±9.3°C, 44.9±12.4°C, 77.3±12.7°C). The same overall trend between the temperatures that resulted from three screw insertion procedures was recorded with significant statistical analyses using either the thermocouple in the screw or the average of several in-bone thermocouples. Placing a single thermocouple in the bone was determined to have limitations in accurately comparing temperatures from different external fixation screw insertion procedures. Using the preferred measurement techniques, a standard screw with a predrilled hole was found to have the lowest maximum temperatures for the shortest duration compared to the other two insertion procedures. Future studies evaluating bone temperature increase need to use reliable temperature measurements for recommending best practices to surgeons. PMID:27246667

    Anesthesiologists occasionally encounter bradycardia during abdominal surgery and recognize the phenomenon as a vagal reflex. The presence of bradycardia implies efferent vagal dominance in the autonomic nervous system during this vagal reflex. In this study, we investigated the effect of abdominal surgical manipulation on autonomic nervous activity, using heart rate variability analysis. Abdominal surgical manipulation decreased the heart rate and enhanced not only the high-frequency power (0.15-0.4 Hz) but also the low-frequency power (0.04-0.15 Hz) calculated from the power spectral density of heart rate variability. Our results suggest that both vagal tone and sympathetic tone could be activated during the vagal reflex caused by abdominal surgical manipulation. PMID:22718015

    Background The surgical robot offers the potential to integrate multiple views into the surgical console screen, and for the assistant’s monitors to provide real-time views of both fields of operation. This function has the potential to increase patient safety and surgical efficiency during an operation. Herein, we present a novel application of the multi-image display system for simultaneous visualization of endoscopic views during various complex robotic gastrointestinal operations. All operations were performed using the da Vinci Surgical System (Intuitive Surgical, Sunnyvale, CA, USA) with the assistance of Tilepro, multi-input display software, during employment of the intraoperative scopes. Three robotic operations, left hepatectomy with intraoperative common bile duct exploration, low anterior resection, and radical distal subtotal gastrectomy with intracorporeal gastrojejunostomy, were performed by three different surgeons at a tertiary academic medical center. Results The three complex robotic abdominal operations were successfully completed without difficulty or intraoperative complications. The use of the Tilepro to simultaneously visualize the images from the colonoscope, gastroscope, and choledochoscope made it possible to perform additional intraoperative endoscopic procedures without extra monitors or interference with the operations. Conclusion We present a novel use of the multi-input display program on the da Vinci Surgical System to facilitate the performance of intraoperative endoscopies during complex robotic operations. Our study offers another potentially beneficial application of the robotic surgery platform toward integration and simplification of combining additional procedures with complex minimally invasive operations.

  17. Quick Response Tracheotomy: A Novel Surgical Procedure.

    PubMed

    Browne, Graeme A

    2016-05-01

    Quick response tracheostomy (QRT) is a novel open surgical technique to emergently establish an airway. The method is simple; the skills necessary to perform this procedure are rapidly acquired; and it is expedient, minimally traumatic, and remarkably devoid of complications often encountered with percutaneous dilatational tracheotomies, including those complications seen with cricothyroidotomies. Unlike all other tracheotomies in which considerable blunt dissection is required, QRT avoids tissue crushing because sharp dissection alone is used to acquire surgical access to the trachea. The QRT does not entail inserting a guidewire into the trachea, a standard feature for percutaneous tracheal access; it avoids any risk of unintended laceration of the posterior tracheal wall and proximal subjacent esophagus. The technique averts tracheal ring fracture and tracheoesophageal fistula complications. The QRT has a uniquely low incidence of inducing hemorrhage, and it requires no steps that cause temporary tracheal occlusion and will therefore not facilitate hypoxia. The QRT contributes minimally to conditions favorable for generating subglottic stenosis, and the procedure is swiftly executed with very low probability for external tracheal placement of the tracheostomy tube. The QRT is not a blind procedure. No special instruments are required for its execution nor is concurrent tracheoscopy required at any stage while performing a QRT as is specified for percutaneous tracheotomies. PMID:26905541

    Summary Pectoralis major (PM) muscle is the powerful dynamic stabiliser of the shoulder that acts as a flexor, adductor and internal rotator. The rupture of the PM tendon is a relatively rare injury that was firstly described in a French boy by Patissier in 1822 and later, in 1861, by Letenneur who reported another similiar case. To date, over 200 cases have been published. In this article we describe the clinical anatomy and the mechanism of injuries of PM and we review the surgical procedures for acute and chronic ruptures.

    2013-01-01

    Objective Despite a growing volume of surgical procedures in low-income and middle-income countries, the costs of these procedures are not well understood. We estimated the costs of 12 surgical procedures commonly conducted in five different types of hospitals in India from the provider perspective, using a microcosting method. Design Cost and utilisation data were collected retrospectively from April 2010 to March 2011 to avoid seasonal variability. Setting For this study, we chose five hospitals of different types: a 57-bed charitable hospital, a 200-bed private hospital, a 400-bed district hospital, a 655-bed private teaching hospital and a 778-bed tertiary care teaching hospital based on their willingness to cooperate and data accessibility. The hospitals were from four states in India. The private, charitable and tertiary care hospitals serve urban populations, the district hospital serves a semiurban area and the private teaching hospital serves a rural population. Results Costs of conducting lower section caesarean section ranged from rupees 2469 to 41 087; hysterectomy rupees 4124 to 57 622 and appendectomy rupees 2421 to 3616 (US$1=rupees 52). We computed the costs of conducting lap and open cholecystectomy (rupees 27 732 and 44 142, respectively); hernia repair (rupees 13 204); external fixation (rupees 8406); intestinal obstruction (rupees 6406); amputation (rupees 5158); coronary artery bypass graft (rupees 177 141); craniotomy (rupees 75 982) and functional endoscopic sinus surgery (rupees 53 398). Conclusions Estimated costs are roughly comparable with rates of reimbursement provided by the Rashtriya Swasthya Bima Yojana (RSBY)—India's government-financed health insurance scheme that covers 32.4 million poor families. Results from this type of study can be used to set and revise the reimbursement rates. PMID:23794591

  20. Changes in muscle strength and pain in response to surgical repair of posterior abdominal wall disruption followed by rehabilitation

    PubMed Central

    Hemingway, A; Herrington, L; Blower, A

    2003-01-01

    Background: Posterior abdominal wall deficiency (PAWD) is a tear in the external oblique aponeurosis or the conjoint tendon causing a posterior wall defect at the medial end of the inguinal canal. It is often known as sportsman's hernia and is believed to be caused by repetitive stress. Objective: To assess lower limb and abdominal muscle strength of patients with PAWD before intervention compared with matched controls; to evaluate any changes following surgical repair and rehabilitation. Methods: Sixteen subjects were assessed using a questionnaire, isokinetic testing of the lower limb strength, and pressure biofeedback testing of the abdominals. After surgery and a six week rehabilitation programme, the subjects were re-evaluated. A control group were assessed using the same procedure. Results: Quadriceps and hamstrings strength was not affected by this condition. A deficit hip muscle strength was found on the affected limb before surgery, which was significant for the hip flexors (p = 0.05). Before surgery, 87% of the patients compared with 20% of the controls failed the abdominal obliques test. Both the injured and non-injured sides had improved significantly in strength after surgery and rehabilitation. The strength of the abdominal obliques showed the most significant improvement over the course of the rehabilitation programme. Conclusions: Lower limb muscle strength may have been reduced as the result of disuse atrophy or pain inhibition. Abdominal oblique strength was deficient in the injured patients and this compromises rotational control of the pelvis. More sensitive investigations (such as electromyography) are needed to assess the link between abdominal oblique function and groin injury. PMID:12547744

  1. Elective plastic surgical procedures in adolescence.

    PubMed

    McGrath, Mary H; Schooler, Wesley G

    2004-10-01

    Adolescent patients are seeking plastic surgery to correct deformities or perceived deformities in increasing numbers. It is essential for the physician to understand the influence of perceived body image irregularity that motivates patients of all ages to request plastic surgery. The increased demand for plastic surgical procedures among young patients is caused partially to increased media exposure to the available procedures offered by plastic surgeons. A successful aesthetic procedure can have a positive influence on a mature, well-motivated teenager, while surgery on a psychologically unstable adolescent can be damaging to the patient. The American Society for Aesthetic Plastic Surgery has developed guidelines for the appropriate selection of teenagers for aesthetic plastic surgery [26]. First, the physician must "assess physical maturity, because operating on a feature that has not yet fully developed could interfere with growth or negate the benefits of surgery in later years." Second, the physician should explore emotional maturity and expectations of the teenager. The teenager should understand the goals and limitations of the proposed surgery and have realistic expectations. Third, only board certified plastic surgeons who operate in accredited facilities should perform these procedures, to ensure the safety of the teenager and the quality of the procedure. Finally, teenagers and their parents should understand the risks of surgery, postoperative restrictions on activity, and typical recovery times. The referring physician and surgeon must be aware of the positive or negative effects that plastic surgery can have on the life of a teenager and be able to select patients who have the motivation, maturity, psychosocial, and emotional attributes that will lead to patient satisfaction.

    Basile, Francesco; Biondi, Antonio; Donati, Marcello

    2013-01-01

    We briefly outline the history of hernia surgery development from the Ebers Papyrus to modern prosthetic repairs. The rapid evolution of anatomical, physiological and pathogenetic concepts has involved the rapid evolution of surgical treatments. From hernia sack cauterization to sack ligation, posterior wall repair (Bassini), and prosthetic reinforcement there has been an evident improvement in surgical treatment results that has stimulated surgeons to find new technical solutions over time. The introduction of prosthetic repair, the laparoscopic revolution, the impact of local anesthesia and the diffusion of day surgery have been the main advances of the last 50 years. Searching for new gold standards, the introduction of new devices has also led to new complications and problems. Research of the last 10 years has been directed to overcome prosthetic repair complications, introducing every year new meshes and materials. Lightweight meshes, composite meshes and biologic meshes are novelties of the last few years. We also take a look at future trends. PMID:24380545

    Pyoderma gangrenosum (PG) is an uncommon, ulcerative skin disease that is often associated with systemic diseases. Herein, we report a development of PG in a surgical site after cholecystectomy that was difficult to discriminate from surgical site infection. The patient was a 74-year-old man who had previously been diagnosed with myelodysplastic syndrome (MDS). Laparoscopic cholecystectomy was planned under diagnosis of cholecystolithiasis, but we converted to open cholecystectomy. The surgical wound was partially erythematous 4 days after surgery. In spite of opening the wound, cleansing it with sterile saline, and administration of antibiotics, inflammation spread with erosion. The clinical manifestations and histopathologic features of biopsy specimen indicated that diagnosis of PG associated with MDS was most likely. Administration of glucocorticoids made a rapid response of skin inflammation. The differential diagnosis of postoperative wound healing complications that were unresponsive to conventional wound local care and antibiotic therapy should include PG, especially in patients with systemic diseases such as MDS.

    Acute cerebrovascular disorders were found in 4.78% of the patients operated on for acute abdominal diseases. Such disorders were revealed during the first 3 days of the postoperative period in 86.9% and appeared as transitory ischemic attacks (21.9%), acute hypertensive encephalopathy (12.4%), ischemic stroke with reversible neurological deficit (27.6%), ischemic stroke with stable neurological deficit (20%), hemorrhagic stroke (2.9%), mixed stroke (2.9%). The pathogenesis of vascular disorder in examined cases included systemic and cerebral hemodynamic disorders, acid-alkaline imbalance, impaired blood gas composition and biochemical and physicochemical blood properties, altered cranial great arteries, cerebrovascular emboli, endogenous intoxication and age-related changes. In the first 24 postoperative hours, actovegin and instenon therapy accelerated neurological deficit regression and recovered cerebral hemodynamics in postoperative strokes. PMID:10957794

    To ensure optimal results, we must do our utmost to achieve targets based on order, symmetry and precision, our ultimate aim being to strive towards the desired harmony, planned contrast and exact proportions. Orthodontic-surgical treatments require specific finishing procedures, which most often call for multidisciplinary, or even transdisciplinary, collaboration. Finishing will involve the dental arches just as much as the orofacial environment. Above all, treatment of this kind demands a highly targeted approach in combination with well-defined and perfectly executed techniques. To finish a case satisfactorily, reasonable targets should be aimed for to ensure they are achieved. One must be ambitious and yet wise. A tight alliance of surgeon and orthodontist will nurture convincing and achievable projects and good, lifelong outcomes. Following the consolidation phase, roughly 4 to 6 weeks post-surgery, we can initiate the final orthodontic treatment, which, in effect, constitutes a mini-treatment in its own right. "Details make perfection, but perfection is not a detail" (Leonardo Da Vinci). "A lucid mind is the ante-chamber of intelligence" (Léo Ferré). In the order of life, every form of unity is always unique, and if each of us is unique, it is because everyone else is too. Ambition, wisdom, lucidity and efficiency will guarantee a successful result, the successful result. We must not be mere observers of our treatments, but the architect, project manager and site foreman at one and the same time. One could talk ad infinitum about finishing orthodontic-surgical cases because everything else leads up to the case-finishing and even the fullest description could never be exhaustive.

    Sink, J D; Myers, R T; James, P M

    1976-05-01

    Over an eight-year peroid at NCBH, 33 patients were operated for ruptured abdominal aortic aneurysm. Factors associated with an increased mortality included preoperative blood urea nitrogen levels of more than 20 mg per cent, severe preoperative hypotension, duration of symptoms of less than 24 hours, free peritoneal rupture and blood transfusions of greater than 19 units. Preoperative hypotension was the most selective preoperative prognostic parameter. From a review of this and other reported series, it was concluded that reduced mortality from ruptured abdominal aortic aneurysm can best be achieved by prompt diagnosis followed by surgical treatment before cardiovascular collapse can occur.

    Objectives To compare the surgical and pathologic outcomes utilizing two surgical approaches for fertility-sparing radical trachelectomy in patients with stage IB1 cervical cancer. Methods A prospectively maintained database of vaginal radical trachelectomy (VRT) and abdominal radical trachelectomy (ART) procedures was analyzed. All procedures were performed in a standardized manner by the same surgical group. Parametrial measurements were recorded from the final pathology report. Standard statistical tests were used. Results Between 12/2001 and 7/2007, 43 adult patients with FIGO stage IB1 cervical cancer underwent surgery with the intent to perform a fertility-sparing radical trachelectomy. VRT was attempted in 28 patients (65%) and ART in 15 patients (35%). The median measured parametrial length in the VRT group was 1.45 cm compared to 3.97 cm in the ART group, P<0.0001. None of the parametrial specimens in the VRT group contained parametrial nodes. Parametrial nodes were detected in 8 (57.3%) of the ART specimens (P=0.0002). There was no difference in histologic subtypes, lymph vascular space invasion, or median total regional lymph nodes removed in the two groups. Median blood loss was greater but not clinically significant in the ART group, and median operating time was less in the ART group. The overall complication rate was not significantly different in the two groups. Conclusions Using standardized techniques, radical abdominal trachelectomy provides similar surgical and pathologic outcomes with possibly a wider parametrial resection, including contiguous parametrial nodes, as compared to the radical vaginal approach.

    The increased technological complexity of surgery and the growing importance of quality assessment demand objective analysis of the surgical process. However, until now no standard method existed for analyzing the peroperative process. In this article, a methodology is discussed to describe and to analyze the surgical process. A method is given to measure the correctness and efficiency of task performance, protocols, and instruments used. In addition, reference values are defined so as to compare new instruments, alternative protocols, and the performance of new tasks with a standard. Finally, recommendations are given for improving new surgical tasks, the development of clinically driven instrument design, and new protocols. PMID:11928035

    Introduction Negative pressure wound therapy (NPWT) for abdominal surgical site infection (SSI) is becoming increasingly common, although enterocutaneous fistula (ECF) has been reported as a complication. To avoid ECF, we used computed tomography (CT) woundgraphy to evaluate the relationship between the wound and the intestine, and then safely treated the abdominal SSI with NPWT. Case presentation Following a laparoscopic intersphincteric resection for low rectal neuroendocrine tumor and covering ileostomy, a 59-year-old woman underwent stoma closure. Six days after surgery, we diagnosed SSI. We suspected ECF, because the wound was deep and the pus resembled enteric fluid. However, CT woundgraphy showed that the wound was separated from the abdominal cavity and the intestine by the abdominal rectus muscle. Accordingly, we performed NPWT. SSI was cured and the wound was well granulated. Twenty-three days after surgery, the patient was discharged. Eventually, the wound was completely epithelialized. Discussion Although successful NPWT has been reported for open abdominal wounds, ECF is a common complication. ECF can be prevented by separating the wound from the intestine by the omentum or muscle fascia, protecting the intestinal serosa during surgery, and applying low vacuum pressure. The relationships among the wound, the fascia, and the intestine must be evaluated before abdominal SSI treatment. One good method is CT woundgraphy, which evaluates wound extent and depth, closure of muscle fascia, and the relationship between the wound and the intestine. Conclusion We report a case of CT woundgraphy before NPWT for abdominal SSI. CT woundgraphy is a good candidate for evaluating wound condition. PMID:27002290

    Fish surgical procedures are commonplace in aquaria, zoos, laboratory facilities, and pet clinical practice. To incorporate fish surgery into a clinical setting, an understanding of anatomic differences between mammals and fish, bath anesthetics, and recirculating anesthesia techniques must be developed; a system or different size systems to accommodate anesthesia and surgery of particular species of concern at an institution or practice constructed; and familiar mammalian surgical principles applied with some adaptations. Common surgical procedures in fish include coeliotomy for intracoelomic mass removal, reproductive procedures, gastrointestinal foreign body removal, radiotransmitter placement, and integumentary mass excision.

    Background: The aim of this study was to define the indicators predicting improved abdominal wall function after surgical repair of abdominal rectus diastasis (ARD). Preoperative subjective assessment quantified by the validated Ventral Hernia Pain Questionnaire (VHPQ) was related to relative postoperative functional improvement in abdominal muscle strength. Methods: Fifty-seven patients undergoing surgery for ARD completed the VHPQ before surgery. Preoperative pain assessment results were compared with the relative improvement in muscle strength measured with the BioDex system 4. Results: There was a correlation between the relative improvement in muscle strength measured by the BioDex System 4 for flexion at 30 degrees (P = 0.046) and 60 degrees per second (P = 0.004) and the preoperative question, “Do you find it painful to sit for more than 30 minutes?” There was also a correlation between BioDex improvement for flexion at 30 degrees (P = 0.022) and for isometric work load (P = 0.038) and the preoperative question, “Has abdominal pain limited your ability to perform sports activities?” The VHPQ responses also formed a pattern with a fairly good correlation between other BioDex modalities (with the exception of extension at 60 degrees per second) and the response to the question regarding complaints when performing sports. Postoperative visual analog scale ratings of abdominal wall stability correlated to the questions regarding complaints when sitting (P = 0.040) and standing (P = 0.047). No other correlation was seen. Conclusion: VHPQ ratings concerning pain while being seated for more than 30 minutes and pain limiting the ability to perform sports are promising indicators in the identification of patients likely to benefit from surgical correction of their ARD.

    We investigated the proportion of orthopaedic procedures supported by evidence from randomised controlled trials comparing operative procedures to a non-operative alternative. Orthopaedic procedures conducted in 2009, 2010 and 2011 across three metropolitan teaching hospitals were identified, grouped and ranked according to frequency. Searches of the Cochrane Central Register of Controlled Trials (CENTRAL), the Cochrane Database of Systematic Reviews (CDSR) and the Database of Abstracts of Reviews of Effects (DARE) were performed to identify RCTs evaluating the most commonly performed orthopaedic procedures. Included studies were categorised as “supportive” or “not supportive” of operative treatment. A risk of bias analysis was conducted for included studies using the Cochrane Collaboration's Risk of Bias tool. A total of 9,392 orthopaedic procedures were performed across the index period. 94.6% (8886 procedures) of the total volume, representing the 32 most common operative procedure categories, were used for this analysis. Of the 83 included RCTs, 22.9% (19/83) were classified as supportive of operative intervention. 36.9% (3279/8886) of the total volume of procedures performed were supported by at least one RCT showing surgery to be superior to a non-operative alternative. 19.6% (1743/8886) of the total volume of procedures performed were supported by at least one low risk of bias RCT showing surgery to be superior to a non-operative alternative. The level of RCT support for common orthopaedic procedures compares unfavourably with other fields of medicine. PMID:24927114

    Blood loss during surgical procedures poses a grave risk to the patient, but transfusion is costly and associated with adverse outcomes. Antifibrinolytics, however, offer an economical and effective means of decreasing blood loss associated with surgical procedures. Tranexamic acid (TXA) is an antifibrinolytic that blocks lysine-binding sites of fibrinogen and fibrin, preventing the breakdown of existing clots. This journal course reviews extensive research demonstrating that antifibrinolytics such as TXA decrease blood loss and in some studies reduce allogeneic transfusion requirements. In addition, this journal course addresses concerns that use of antifibrinolytics increases embolic events, reviews research that demonstrates TXA does not increase the incidence of vascular occlusive events, and describes methods of TXA use in cardiac and orthopedic surgical procedures, neurosurgery, and obstetrics. The Certified Registered Nurse Anesthetist should consider the possibility, on a case-by-case basis, of using TXA in surgical procedures to reduce blood loss with minimal adverse effects.

    The historical pathway to current surgical endodontic procedures and their applications has been tortuous and tumultuous. Influenced heavily in their development by the European sector, these surgical procedures faced many challenges over the decades. Fortunately for today's practitioners, influential members of the oral surgery community, and a few staunch believers in retaining devitalized teeth, persisted in their investigation of and search for improved procedures that had predictable outcomes. Many so-called "revolutionary" or newer techniques practiced today are but a re-emergence of surgical concepts that were lost in the archives of time. With the advent of evidence-based endodontics, these procedures are now supported extensively by science and by the integration of science into materials usage, technique applications and outcomes research. However, in many respects, this story is just beginning, as the "roots" of surgical endodontics are explored. PMID:20491369

High rates of adverse events and complaints have been reported in surgical procedures. This article analyzes the claims registered by the Council of Medical Colleges in Catalonia between 1986 and 2012, and explores surgical procedures claimed (ICD- 9-CM coding), as well as the final outcome of the claim. Among the 5,419 records identified on surgical procedures, the interventions of the musculoskeletal system and skin and integument showed the highest frequencies. Interventions related to "non-curative" medicine should be emphasized because of their higher rates of economical agreement or condemnation outcomes, which were significantly higher for mastopexia. The results underscore the importance of the surgical area in medical professional liability and the high risk of payouts among those procedures belonging to the so-called "non-curative" medicine.

    Postoperative collection is a known complication of abdominal surgery, especially after major surgery; however, minor surgical procedures may also be associated with this phenomenon. Utilization of nonsteroidal anti-inflammatory drugs, such as lornoxicam, and the adverse effects thereof, may affect the surgeon's judgment regarding the need for, and extent of, draining of these collections. Here I report the case of a 25-year-old male who presented with perforated acute retrocaecal subhepatic appendicitis complicated by pleural effusion and a small abdominal collection. The pleural effusion resolved almost completely over time. However, the patient showed incomplete recovery, as demonstrated by nausea, vomiting, and mood disturbance along with abdominal pain, tachycardia, and a persistent small abdominal collection. We initially suspected infection caused by a highly virulent type of bacteria and planned to perform percutaneous drainage. However, owing to skin erythematic changes, administration of lornoxicam was ceased, which resulted in complete recovery of the symptoms and consequently in avoidance of unnecessary invasive intervention to drain the abdominal collection. These findings suggest that the utilization and adverse effects of some painkillers for postoperative pain, such as lornoxicam, may affect the surgeon's judgment regarding the most appropriate surgical workup in cases of postoperative fluid collection.

    Abstract We aimed to present a combined surgical procedure in conservative treatment of placenta accreta based on surgical outcomes in our cohort of patients. The study was designed as a prospective cohort series study. The setting involved two education and research hospitals in Turkey. This study included 12 patients with placenta accreta who were prenatally diagnosed and managed. We offered the patients the choice of conservative or nonconservative treatment. We then offered 2 choices for patients who had preferred conservative treatment, leaving the placenta in situ as is the classical procedure, or our surgical procedure. One patient preferred nonconservative treatment, the others opted for our procedure. We evaluated demographic and obstetric characteristics of patients, sonographic and operative parameters of patients, and surgical outcomes. We operated on 11 patients using this surgical procedure that we have developed for placenta accreta cases. We found that there was no need for hysterectomy in any patient, and we preserved the uterus for all of these patients. No patient presented any septic complication or secondary vaginal bleeding. Our surgical procedure seems to be effective and useful in the conservative treatment of placenta accreta. PMID:25700315

    Each concept in the surgical operations chapter of the Read Thesaurus has been analysed to determine its anatomical site component. The underlying structure of this chapter and its relationship to the anatomy chapter are explored. The defined anatomical sites have been included as atomic maps in the Read Code template table, one of the key component files of the Thesaurus, relevant features of which are described. The analysis methodology is outlined and the value of an anatomically characterised surgical procedure terminology is discussed together with the implications of semantically defining a wider range of characteristics of surgical procedures.

    Mortality due to the surgical treatment of ruptured abdominal aortic aneurysms (RAAA) is high, more than 40%, especially in elderly patients. The literature concerning RAAA in very elderly patients is analyzed by Internet research (Medline). Only rare examples of emergency surgical management in nonagenarian patients are reported, and even fewer reports of successfully operated patients. A case report of a successful surgical repair of RAAA in a nonagenarian is presented. After ultrasound (US) and CT scans, the patient (in good condition as regards blood pressure, respiratory, cardiac and renal function) underwent uneventful aneurysmectomy and reconstruction of the aorta and common iliac arteries by means of a bifurcated prosthesis. The length of hospitalization was 30 days and the patient is still alive and in good condition four years and two months after the operation. The advisability of emergency surgical repair in these patients, questionable because of the excessive surgical risk and poor survival benefit, is discussed. However many other factors affect the outcome of emergency repair (mainly cardiac, respiratory and renal function), independently of age. The authors conclude that age per se does not limit the indication for or success of surgery in very elderly patients. PMID:11782704

    This study assessed perioperative complications in abdominal sacrocolpopexy and vaginal sacrospinous ligament fixation procedures. Perioperative complications were defined as any complication occurring during surgery or the first 6 weeks postoperatively. Forty-five patients underwent abdominal procedures (20 sacrohysteropexy and 25 sacrocolpopexy) and 60 patients underwent vaginal sacrospinous fixation. Of the 105 patients, 13 had vaginal vault prolapse. In the abdominal group, one bladder injury, four hemorrhages, and three wound dehiscences occurred. In the vaginal group, one rectal injury and one postoperative vaginal vault infection occurred. Major and minor complications were more frequent in the abdominal group than in the vaginal group. Blood loss was not significantly different. The operating time and hospital stay in the abdominal group were significantly longer than in the vaginal group. In conclusion, abdominal sacrocolpopexy had a higher rate of perioperative complications and longer hospital stay and operating time. PMID:16688396

    The aim of this study was to explore the pre- and postsurgical journey to correct severe abdominal lipodystrophy of a woman living as AIDS defined for over 23 years. It utilized interpretative phenomenological analysis (IPA) and a single-case-study approach to capture the subjective understanding and sense-making of this surgical process. Verbatim transcripts of seven semi-structured interviews, three participant-created word boards of words or phrases clipped from magazines, field notes, and a reflexive journal were collected as data. Analysis revealed two superordinate themes: the unknown and the unanticipated. These themes simultaneously manifest with shared and nuanced meanings, including the unknown and unanticipated of surviving AIDS and discovering lipodystrophy, the unknown and the unanticipated of the surgical intervention itself, and finally the unknown and the unanticipated of postsurgical complications and experiences within outpatient and inpatient medical settings.

    OBJECTIVE To evaluate peripheral blood and abdominal fluid variables as predictors of intestinal surgical site failure in dogs with septic peritonitis following celiotomy and closed-suction abdominal drain (CSAD) placement. DESIGN Prospective study. ANIMALS 26 dogs with septic peritonitis that underwent celiotomy and CSAD placement. PROCEDURES Abdominal fluid and blood samples were collected prior to surgery and daily thereafter until CSAD removal. Abdominal fluid was collected through the CSAD. Analysis of all samples included pH, PCO2, PO2, PCV, WBC count, and total solids, glucose, lactate, and electrolyte concentrations. Abdominal fluid samples also underwent cytologic evaluation and bacterial culture, and the volume of fluid removed through the drain was recorded daily. The blood-to-fluid glucose and lactate differences, fluid-to-blood lactate ratio and blood-to-fluid WBC and neutrophil ratios were determined daily. Dogs were categorized into 2 groups on the basis of whether they had an uneventful recovery (UR) or developed postoperative septic peritonitis (POSP). RESULTS 23 dogs had a UR and 3 developed POSP. On the third day after surgery, the abdominal fluid WBC count was significantly lower and the blood-to-fluid WBC and neutrophil ratios were significantly higher for dogs in the POSP group, compared with those for dogs in the UR group. None of the other blood and abdominal fluid variables assessed differed significantly between the 2 groups. CONCLUSIONS AND CLINICAL RELEVANCE Results failed to identify any objective predictive indicators for POSP in dogs with CSADs. Use of blood-to-fluid WBC and neutrophil ratios as predictive indicators for POSP requires further investigation. PMID:27556266

    Surgical site infections (SSI) are an uncommon, but significant, consequence of surgical interventions. There are very few studies investigating SSI risk in veterinary medicine, and even fewer in cattle, despite the fact that major surgeries are commonly conducted on livestock. Furthermore, the suboptimal conditions under which such surgeries are frequently performed on livestock could be considered an important risk factor for the development of SSIs. With increasing public concern over the contribution of veterinary-prescribed antimicrobials to the emergence of antimicrobial-resistant bacteria in people, there is widespread scrutiny and criticism of antimicrobial use in livestock production medicine systems. While the causal link between antimicrobial resistance in livestock and people is heavily debated, it is clear that the prevalence of antimicrobial resistance, in any population, is closely correlated with the antimicrobial 'consumption' within that population. As the veterinary profession explores ways of addressing the emergence and selection of antimicrobial-resistant bacteria in food-producing animals, there is a need for veterinarians and producers to carefully consider all areas of antimicrobial use, and employ an evidence-based approach in designing appropriate clinical protocols. This paper aims to review current knowledge regarding the risk factors related to abdominal SSI in periparturient cows, and to encourage practitioners to judiciously evaluate both their standard operating procedures and their use of antimicrobials in these situations. In a second paper, to be published in a subsequent issue of Veterinary Record, these principles will be used to provide specific evidence-based recommendations for antimicrobial use in bovine abdominal surgery.

    Although medical treatment and endoscopic interventions are primarily offered to patients with chronic pancreatitis, approximately 40% to 75% will ultimately require surgery during the course of their disease. Although pancreaticoduodenectomy has been considered the standard surgical procedure because of its favorable results on pain control, its high postoperative complication and pancreatic exocrine or/and endocrine dysfunction rates have led to a growing enthusiasm for duodenal preserving pancreatic head resection. The aim of this review is to better understand the rationale underlying of the Frey procedure in chronic pancreatitis and to analyze its outcome. Because of its hybrid nature, combining both resection and drainage, the Frey procedure has been conceptualized based on the pathophysiology of chronic pancreatitis. The short and long-term outcome, especially pain relief and quality of life, are better after the Frey procedure than after any other surgical procedure performed for chronic pancreatitis.

    Aim: To describe a technique of phalloplasty that is devoid of donor site scarring and suitable for urethral inlay and penile prosthesis in subsequent stages in cases of aphallia. Materials and Methods: Four patients with various disorders of sex development with 46 XY and severe penile deficiency, including one with complete androgen insensitivity syndrome who was initially raised as female, have been operated using a “Bird Wing” lower abdominal skin crease incision. Results: The patients’ age ranged from 6 to 17 years with preoperative stretched penile lengths between 1 and 2.5 cm. Phallic sizes between 7.5 and 12.5 cm was achieved leaving the donor site unremarkable with lower abdominal skin crease linear scar and excellent postoperative recovery. Conclusions: This phalloplasty technique can be utilized as a definitive procedure in many situations of penile insufficiency. Subsequent stages of urethral repair and insertion of penile prosthesis can be easily added. PMID:23798805

    PurposeTo investigate the causes and results of late open surgical conversion (LOSC) after failed abdominal aortic aneurysm repair (EVAR) and to summarize our 17 years’ experience with 13 various endografts.MethodsRetrospective data from August 1994 to January 2011 were analyzed at our center. The various devices’ implant time, the types of devices, the rates and causes of LOSC, and the procedures and results of LOSC were analyzed and evaluated.ResultsA total of 1729 endovascular aneurysm repairs were performed in our single center (Nuremberg South Hospital) with 13 various devices within 17 years. The median follow-up period was 51 months (range 9–119 months). Among them, 77 patients with infrarenal abdominal aortic aneurysms received LOSC. The LOSC rate was 4.5 % (77 of 1729). The LOSC rates were significantly different before and after January 2002 (p < 0.001). The reasons of LOSC were mainly large type I endoleaks (n = 51) that were hard to repair by endovascular techniques. For the LOSC procedure, 71 cases were elective and 6 were emergent. The perioperative mortality was 5.2 % (4 of 77): 1 was elective (due to septic shock) and 3 were urgent (due to hemorrhagic shock).ConclusionLarge type I endoleaks were the main reasons for LOSC. The improvement of devices and operators’ experience may decrease the LOSC rate. Urgent LOSC resulted in a high mortality rate, while selective LOSC was relatively safe with significantly lower mortality rate. Early intervention, full preparation, and timely LOSC are important for patients who require LOSC.

    Introduction Chronic pancreatitis (CP) can be a cause of recurrent, severe, disabling abdominal pain in children. Surgery has been suggested as a useful therapy, although experience is limited and the results unpredictable. We reviewed our experience of a two-stage protocol-preliminary endoscopic retrograde cholangiopancreatography (ERCP) and duct stenting, and if symptoms resolved, definitive surgical decompression by longitudinal pancreatojejunostomy (LPJ) (Puestow operation). Patients and Methods This is a single-center, retrospective review of children with established CP who underwent an LPJ between February 2002 and September 2012. A questionnaire was completed (incorporating visual analog scale pain and lifestyle scores) to assess functional outcome. Data are expressed as median (range). Results In this study, eight (M:F ratio of 4:4) children underwent an LPJ and one female child had a more limited pancreatojejunostomy anastomosis following preliminary ERCP and stent placement where possible. Diagnoses included hereditary pancreatitis (n = 3), idiopathic or structural pancreatitis (n = 5), and duct stricture following radiotherapy (n = 1). Median duct diameter presurgery was 5 (4-11) mm. Endoscopic placement of a Zimmon pancreatic stent was possible in six with relief of symptoms in all. Median age at definitive surgery was 11 (range, 7-17) years with a median postoperative stay of 9 (range, 7-12) days and a follow-up of 6 (range, 0.5-12) years. All children reported markedly reduced episodes of pain postprocedure. One developed diabetes mellitus, while three had exocrine deficiency (fecal elastase < 200 µg/g) requiring enzyme supplementation. The child with limited LPJ had symptomatic recurrence and required restenting and further surgery to widen the anastomosis to become pain free. Conclusion ERCP and stenting provide a therapeutic trial to assess possible benefit of a definitive duct drainage procedure. LPJ-the modified Puestow

  13. Radiation exposure from fluoroscopy during orthopedic surgical procedures

    The use of fluoroscopy has enabled orthopedic surgeons to become technically more proficient. In addition, these surgical procedures tend to have less associated patient morbidity by decreasing operative time and minimizing the area of the operative field. The trade-off, however, may be an increased risk of radiation exposure to the surgeon on an annual or lifetime basis. The current study was designed to determine the amount of radiation received by the primary surgeon and the first assistant during selected surgical procedures involving the use of fluoroscopy. Five body sites exposed to radiation were monitored for dosage. The results of this study indicate that with appropriate usage, (1) radiation exposure from fluoroscopy is relatively low; (2) the surgeon's dominant hand receives the most exposure per case; and (3) proper maintenance and calibration of fluoroscopic machines are important factors in reducing exposure risks. Therefore, with proper precautions, the use of fluoroscopy in orthopedic procedures can remain a safe practice.

    In many types of surgery, especially orthopedic procedures, power tools such as saws and drills are used. These tools can impart considerable energy in disrupting tissue and may produce aerosolized blood and material from bone and other tissues. Surgical lasers and electrocautery tools can also produce aerosols due to vaporization of blood and tissues. A number of studies have been reported concerning production of aerosols during surgery, and some of the aerosols produced may contain infectious materials. Health care workers have expressed concern and questions pertaining to the occupational transmission of blood-borne pathogens including the human immunodeficiency virus (HIV) and hepatitis B virus (HBV) via blood aerosols during surgery. Little or no data existed characterizing the aerosols produced performing surgical procedures. Because of this lack of data, the National Institute for Occupational Safety and Health funded a project at ITRI to assess the extent of aerosolization of blood and other tissues during surgical procedures in the laboratory and in a hospital surgical suite.

    The effect of short surgical procedures on paracetamol elimination was studied in seven male patients undergoing surgery with epidural anaesthesia. Five healthy volunteers who did not undergo surgery served as a control group. Paracetamol concentration was measured in saliva at various intervals 1 day before and after surgery. Paracetamol half-life (t1/2,z) decreased and metabolic clearance rate (CL) increased after surgery as compared to preoperative values. The results suggest that surgical stress may enhance the hepatic metabolism of paracetamol. PMID:4041337

    Abstract Background: Perforations of surgical gloves are common and increase with the duration of glove wear. Skin flora, re-grown after pre-operative disinfection of the hands, may contaminate a surgical site. An antimicrobial surgical glove with chlorhexidine on its inner surface has been developed. We hypothesized that by suppressing the re-growth of skin flora during the complete course of a surgical procedure, antimicrobial gloves may reduce the risk of surgical site contamination in the event of an intra-operative glove breach. Methods: We conducted a randomized, double-blind, single-center trial, to measure any differences in the bacterial skin populations of surgeons' hands during surgical procedures done with antimicrobial and non-antimicrobial surgical gloves [ISRCTN71391952]. In this study, 25 pairs of gloves were retrieved from 14 surgeons who donned them randomly on their dominant or non-dominant hand. The number of bacteria retrieved from glove fluid was measured and expressed as colony forming units (CFU)/mL. Results: The median cfu/mL of antimicrobial gloves was 0.00 (LQ: 0.00 CFU/mL; UQ: 0.00 cfu/mL), with a mean log10 cfu/mL=0.02 (range: 0.00–0.30). The median CFU/mL of non-antimicrobial gloves was 54.00 (LQ: 3.00 cfu/mL; UQ: 100.00 cfu/mL) with a mean log10 CFU/mL=1.32 (range: 0.00–2.39). After a mean operating time of 112 min, the difference in the log10 CFU/mL was 1.30 (p<0.001). Conclusions: A new antimicrobial surgical glove suppressed surgeons' hand flora during operative procedures. In the event of a glove breach, the use of such a glove may have the potential to prevent bacterial contamination of a sterile surgical site, thereby decreasing the risk of surgical site infection (SSI) and increasing patient safety. Further clinical studies are needed to confirm this concept. PMID:24116857

    We report a case of an indwelling inferior vena cava filter that penetrated the IVC wall after Whipple’s pancreatico-duodenectomy procedure performed in a patient with ampullary carcinoma, resulting in right ureteral injury and obstruction with subsequent hydroureter and hydronephrosis. This was incidentally discovered on a computed tomography scan performed as routine follow up to evaluate the results of the surgery. We retrieved the inferior vena cava filter and placed a nephrostomy catheter to relieve the ureteral obstruction. Our case highlights the importance of careful inferior vena cava manipulation during abdominal surgery in the presence of an inferior vena cava filter, and the option of temporary removal of the filter to be placed again after surgery in order to avoid this complication, unless protection is required against clot migration during the surgical procedure.

    The goal of this study was to make a Medline research about pregnancies which occur after surgical procedures for stress urinary incontinence (SUI). Therefore, we do not know the recurrence rate of SUI after pregnancy and the influence of the way of delivery on the risk of recurrence. We do not know either if we should apply a surgical procedure on women who have not achieved their pregnancies. In 1998, a questionnaire based survey conducted in the USA showed a lower risk of recurrence after a caesarean section than after a vaginal delivery (p=0,03) when women had previously colposuspension or sling procedures. We found ten case reports and a French national survey (2006) about pregnancies after TOT or TVT procedure. No complication related to the tape was described during pregnancy. The recurrence rate along the pregnancy is about 15%, and the global recurrence rate (during pregnancy and after the childbirth) is about 20%. As a conclusion, pregnancy itself has an influence, and vaginal delivery seams to increase the risk of recurrence after the birth compare to the c-section. However this recurrence rate and these data do not appear enough to us to refuse a surgical treatment for women who have not completed their pregnancies and who suffer from UI without efficacy of physiotherapy. We do not have objective data to assess the best way of delivery. Further and large studies are needed although they are difficult to be carried through. PMID:19117785

    Objective: To evaluate the cosmetic and functional results of patients submitted to surgical correction of Congenital High Scapula (Sprengel's Deformity) using modified Green's Procedure, as well as patients' satisfaction and complications. Methods: Nine patients submitted to surgical treatment from September 1993 to April 2008 have been assessed. The modification from original technique was: subperiosteal muscle detachment, resection of superomedial scapular portion and fixation of medial portion of scapular spine to contralateral posterior iliac crest instead of skeletal traction, with subcutaneous wire. The mean age was 7 years and 3 months. The mean follow-up time was 3 years and 7 months. Results: The mean improvement in forward elevation was 39o (range 0 to 80o). According to the Cavendish Classification, cosmetic improvement of two degrees was achieved in eight cases, and three degrees in one. All patients were satisfied with results. Conclusions: Surgical correction of Sprengel's Deformity by a modified Green's procedure with contralateral posterior iliac crest fixation instead of skeletal traction, showed both cosmetic and functional improvements; all patients and/or family members were satisfied with the results, and the complications associated to the surgical technique did not interfere on end results.

    Authorities are not in full agreement in regard to risk of surgery in the elderly. One hundred eight studies of surgery in the elderly over the past 40 years were reviewed. The purpose was not merely to tabulate results, but to identify differences existing between reports with regard to data reported that could affect results independent of the surgical management itself. Sources of variance that need to be taken into account in comparing mortality rates between studies, such as whether mortality was computed by number of patients or operations, differing lengths of follow-up for recording mortality, proportions of emergency versus elective operations, and types of surgical procedures, were documented. A nine-item confidence in results scale was used to classify studies into high and low confidence groups. Surgical specialties scored substantially higher than general surgical studies. More recent studies received higher scores than earlier studies. Although mortality rates varied widely depending on methods of their calculation, there appeared to be a trend toward increases in elective, but not emergency, mortality rates in general surgery since 1941 that should be examined more closely. One thing that cannot be answered clearly from these studies is the relative risk of surgery with age. Some control of variations between studies and standardization of reporting surgical deaths are required before risk of surgery in the elderly can be assessed more accurately. PMID:7055387

    Background and Objective Prospective studies that investigated the influence of surgical and nonsurgical procedures in the recurrence of periodontitis and tooth loss in periodontal maintenance therapy (PMT) programs have not been previously reported. The objective of this study was to evaluate longitudinally the recurrence of periodontitis in regular compliers (RC) and irregular compliers (IC) individuals undergoing surgical and non-surgical procedures over 5 years in a program of PMT. Materials and Methods A total of 212 individuals participated in this study. Full-mouth periodontal examination including bleeding on probing, probing depth, and clinical attachment level were determined at all PMT visits over 5 years. The recurrence of periodontitis was evaluated in RC and IC individuals undergoing surgical and non-surgical procedures in PMT. The influences of risk variables of interest were tested through univariate analysis and multivariate logistic regression. Results Recurrence of periodontitis was significantly lower among RC when compared to IC. Individuals with recurrence of periodontitis and undergoing surgical procedures showed higher probing depth and clinical attachment loss than those who received non-surgical procedures. Recurrence of periodontitis was higher in individual undergoing surgical procedures and irregular compliance during PMT. Conclusions Irregular compliance and surgical procedures in individuals undergoing PMT presented higher rates of recurrence of periodontitis when compared to regular compliant patients undergoing non-surgical procedures.

    Trigeminal neuralgia (TN) is a debilitating ailment. Pharmacotherapy still remains the first line therapy for the management of TN. However, often the patients become refractory to the pharmacotherapy and need surgical interventions. There is a wide array of surgical treatment modalities available for TN and it is important to select the most appropriate surgery for a patient. This review evaluates the various surgical modalities by employing a comparative analysis with respect to patient selection, success rate, complications and cost effectiveness. For the evaluation, a critical review of literature was done with predefined search terms to obtain the details of individual procedures, which were then compared, under similar parameters. The results suggested that microvascular decompression seem to be the most effective treatment in terms of patient satisfaction and long term cost effectiveness. However, if patient factors do not permit, then the peripheral procedures may be employed as a substitute, though they have higher recurrence rate and complications and have relatively lower long term cost effectiveness. The newer modalities like stereotactic radiosurgery and botulinum injections have promising results and further refinement in these procedures will provide additional options for the patients suffering from TN.

    When veterinary students face their first live animal surgeries, their level of anxiety is generally high and this can affect their ability to recall the procedure they are about to undertake. Multimodal teaching methods have previously been shown to enhance learning and facilitate recall; however, student preferences for recollection methods when translating theory into practice have not been documented. The aim of this study was to investigate veterinary students' experience with recollection of a surgical procedure they were about to perform after using multiple methods for preparation. From a group of 171 veterinary students enrolled in a basic surgery course, 26 students were randomly selected to participate in semi-structured interviews. Results showed that 58% of the students used a visual, dynamic method of recollection, mentally visualizing the video they had watched as part of their multimodal preparation. A mental recipe was used by 15%, whereas 12% mentally visualized their own notes. The study provides new information regarding veterinary students' methods of recollection of surgical procedures and indicates that in Danish veterinary students, a visual dynamic method is the most commonly used. This is relevant information in the current educational situation, which uses an array of educational tools, and it stresses the importance of supporting the traditional surgical teaching methods with high-quality instructional videos.

    The trend toward transoral access, be it for pathology or facial cosmetic surgery, has become increasingly popular over the last two decades with facial incisions being used more and more sporadically than otherwise. Transoral access because of its inherent limitations, retraction of the oral and perioral tissues without inducing physical or thermal injury makes it a daunting task for the operating surgeon. The use of conventional retractors in conjunction with surgical instruments can lead to inadvertent injury to the perioral tissues resulting in untoward postoperative sequelae leading to patient discomfort and delayed recovery. This article elucidates the versatility of a simple photographic retractor (spandex) as a useful adjunctive tool in the retraction and protection of the perioral tissues for almost all transoral surgical procedures.

    Medical surgical nurses may not have the time or resources to provide effective pre- and post-operative instructions for patients in today's healthcare system. And, making timely physical assessments following discharge from the hospital is not always straightforward. Therefore, the risk for readmission associated with post-surgical complications is a concern. At present, mobile healthcare technologies and patient care are precipitously evolving and may serve as a resource to enhance communication between the healthcare provider and patient. A mobile telephone text message (short message service [SMS]) intervention for abdominal surgical patients may foster effective education (communication) and timely self-reported physical assessment in the home environment hence preventing deleterious outcomes. The aim of this research proposal is to identify the feasibility of using a SMS intervention via smart phones to improve health outcomes via timely communication, reach large numbers of at-risk surgical patients and, establish and sustain uniform protocols in a cost-efficient manner.

    A series of 50 patients with carcinoma of the breast underwent omental transposition. This palliative procedure is indicated for recurrences after conservative treatment, radiation necrosis and Stage III or IV ulcerated tumors. The operative technique is described in detail. Omentoplasties were performed upon 33 right and 17 left mammary areas. Forty-five right pedicled flaps and only four left areas were used. One patient died on the fourth postoperative day because of massive pulmonary embolus. Local repair was satisfactory in 76 per cent of the patients. Four patients presented with herniation of the abdominal wall at the site of omental tunneling. In three, the treatment consisted of sectioning the vascular pedicle and reinforcing the parietal closure with Dacron (polyester fiber) mesh. PMID:2305346

    Living donor liver resections are associated with significant postoperative pain. Epidural analgesia is the gold standard for postoperative pain management, although it is often refused or contraindicated. Surgically placed abdominal wall catheters (AWCs) are a novel pain modality that can potentially provide pain relief for those patients who are unable to receive an epidural. A retrospective review was performed at a single center. Patients were categorized according to their postoperative pain modality: intravenous (IV) patient-controlled analgesia (PCA), AWCs with IV PCA, or patient-controlled epidural analgesia (PCEA). Pain scores, opioid consumption, and outcomes were compared for the first 3 postoperative days. Propensity score matches (PSMs) were performed to adjust for covariates and to confirm the primary analysis. The AWC group had significantly lower mean morphine-equivalent consumption on postoperative day 3 [18.1 mg, standard error (SE)=3.1 versus 28.2 mg, SE=3.0; P=0.02] and mean cumulative morphine-equivalent consumption (97.2 mg, SE=7.2 versus 121.0 mg, SE=9.1; P=0.04) in comparison with the IV PCA group; the difference in cumulative-morphine equivalent remained significant in the PSMs. AWC pain scores were higher than those in the PCEA group and were similar to the those in the IV PCA group. The AWC group had a lower incidence of pruritus and a shorter hospital stay in comparison with the PCEA group and had a lower incidence of sedation in comparison with both groups. Time to ambulation, nausea, and vomiting were comparable among all 3 groups. The PSMs confirmed all results except for a decrease in the length of stay in comparison with PCEA. AWCs may be an alternative to epidural analgesia after living donor liver resections. Randomized trials are needed to verify the benefits of AWCs, including the safety and adverse effects.

    Objectives The aim of this article is to make an evaluation on the clinical features of patients with Kawasaki disease who require a cardiac surgical procedure including coronary artery bypass grafting, coronary arterial aneurysmorrhaphy or heart transplantation. Methods English literature of Kawasaki disease for cardiac surgery (1990–2011) was retrieved in the Pubmed database. The clinical features of the patient setting from the representative articles were collected and analyzed. Results Patients with Kawasaki disease were very young, with some requiring a cardiac surgical procedure at a very early age. The interval between the onset and the surgical operation was 9.5±9.4 years. The prevalence of myocardial infarction and re-infarction was high. Giant aneurysm, critical stenosis with calcification and thrombus formation of the coronary arteries often warrant coronary artery bypass, heart transplantation or coronary arterial aneurysm plication. The left internal mammary artery to the left anterior descending coronary artery was the most commonly used graft in coronary artery bypass. Graft patency rate was 82.4% at 21.4±32.3 (range 0.1–252) month follow-up. The early and late mortalities of this patient setting were 0.6 and 3.0%, respectively. Conclusions Patients with Kawasaki disease may develop coronary artery lesions prone to aneurysmal formation with calcification and thrombus and may require coronary artery bypass at a very early age. With the left internal mammary artery as the first choice of bypass graft, the long-term patency and patient survival was satisfactory. PMID:23226165

    Routine hernia repair surgery involves the implant of synthetic mesh. However, this type of procedure may give rise to pain and bowel incarceration and strangulation, causing considerable patient disability. The purpose of this study was to compare the long-term behaviour of three commercial meshes used to repair the partially herniated abdomen in New Zealand White rabbits: the heavyweight (HW) mesh, Surgipro(®) and lightweight (LW) mesh, Optilene(®), both made of polypropylene (PP), and a mediumweight (MW) mesh, Infinit(®), made of polytetrafluoroethylene (PTFE). The implanted meshes were mechanical and histological assessed at 14, 90 and 180 days post-implant. This behaviour was compared to the anisotropic mechanical behaviour of the unrepaired abdominal wall in control non-operated rabbits. Both uniaxial mechanical tests conducted in craneo-caudal and perpendicular directions and histological findings revealed substantial collagen growth over the repaired hernial defects causing stiffness in the repair zone, and thus a change in the original properties of the meshes. The mechanical behaviour of the healthy tissue in the craneo-caudal direction was not reproduced by any of the implanted meshes after 14 days or 90 days of implant, whereas in the perpendicular direction, SUR and OPT achieved similar behaviour. From a mechanical standpoint, the anisotropic PP-lightweight meshes may be considered a good choice in the long run, which correlates with the structure of the regenerated tissue. PMID:22100101

    Background Variability in case exposures has been identified for orthopaedic surgery residents. It is not known if this variability exists for peripheral nerve procedures. Objective The objective of this study was to assess ACGME case log data for graduating orthopaedic surgery, plastic surgery, general surgery, and neurological surgery residents for peripheral nerve surgical procedures and to evaluate intraspecialty and interspecialty variability in case volume. Methods Surgical case logs from 2009 to 2014 for the 4 specialties were compared for peripheral nerve surgery experience. Peripheral nerve case volume between specialties was performed utilizing a paired t test, 95% confidence intervals were calculated, and linear regression was calculated to assess the trends. Results The average number of peripheral nerve procedures performed per graduating resident was 54.2 for orthopaedic surgery residents, 62.8 for independent plastic surgery residents, 84.6 for integrated plastic surgery residents, 22.4 for neurological surgery residents, and 0.4 for surgery residents. Intraspecialty comparison of the 10th and 90th percentile peripheral nerve case volume in 2012 revealed remarkable variability in training. There was a 3.9-fold difference within orthopaedic surgery, a 5.0-fold difference within independent plastic surgery residents, an 8.8-fold difference for residents from integrated plastic surgery programs, and a 7.0-fold difference within the neurological surgery group. Conclusions There is interspecialty and intraspecialty variability in peripheral nerve surgery volume for orthopaedic, plastic, neurological, and general surgery residents. Caseload is not the sole determinant of training quality as mentorship, didactics, case breadth, and complexity play an important role in training. PMID:27168883

    A homogeneous illumination of intra-abdominal organs is essential for successful photodynamic therapy of the abdominal cavity. Considering the current lack of outstanding light-delivery systems, a new illumination procedure was assessed. A rat model of peritoneal carcinomatosis was used. Four hours after intraperitoneal injection of hexaminolevulinate, a square illuminating panel connected to a 635-nm laser source was inserted vertically into the abdominal cavity. The abdominal incision was sutured and a pneumoperitoneum created prior to illumination. Light dosimetry was based on the calculation of the peritoneal surface by MRI. The rats were treated with a light dose of 20, 10, 5 or 2.5 J/cm2 administered continuously with an irradiance of 7 mW/cm2. The homogeneity of the cavity illumination was assessed by quantification of the photobleaching of the tumor lesions according to their localization and by scoring of that of the liver and of the bowel immediately after treatment. Photobleaching quantification for tumor lesions relied on the calculation of the fluorescence intensity ratio (after/before treatment) after recording of the lesions during blue-light laparoscopy and determination of their fluorescence intensity with Sigmascan Pro software. The procedure led to a homogeneous treatment of the abdominal cavity. No statistical difference was observed for the photobleaching values according to the localization of the lesions on the peritoneum (p=0.59) and photobleaching of the liver and of the intestine was homogeneous. We conclude that this procedure can successfully treat the major sites involved in peritoneal carcinomatosis.

    The healthcare sector is a driver of economic growth in the U.S., with spending on healthcare in 2012 reaching $2.8 trillion, or 17% of the U.S. gross domestic product, but it is also a significant source of emissions that adversely impact environmental and public health. The current state of the healthcare industry offers significant opportunities for environmental efficiency improvements, potentially leading to reductions in costs, resource use, and waste without compromising patient care. However, limited research exists that can provide quantitative, sustainable solutions. The operating room is the most resource-intensive area of a hospital, and surgery is therefore an important focal point to understand healthcare-related emissions. Hybrid life cycle assessment (LCA) was used to quantify environmental emissions from four different surgical approaches (abdominal, vaginal, laparoscopic, and robotic) used in the second most common major procedure for women in the U.S., the hysterectomy. Data were collected from 62 cases of hysterectomy. Life cycle assessment results show that major sources of environmental emissions include the production of disposable materials and single-use surgical devices, energy used for heating, ventilation, and air conditioning, and anesthetic gases. By scientifically evaluating emissions, the healthcare industry can strategically optimize its transition to a more sustainable system. PMID:25517602

    Cystic echinococcosis (CE) is a globally distributed zoonosis caused by the Echinococcus granulosus sensu lato species complex. Four approaches are available for treatment of abdominal CE: surgery, percutaneous aspiration, chemotherapy with albendazole, and watch-and-wait. Allocation of patients to these different treatment options mainly depends on the stage of the cystic lesion. However, as available guidelines are not widely followed, surgery is often applied even without the correct indication outside referral centers. This is not only a disadvantage for the patient, but also a waste of money. In this study, we evaluated the cost of the surgical approach for abdominal CE by analyzing hospitalization costs for 14 patients admitted to the General Surgery Ward at the "San Matteo" Hospital Foundation in Pavia, Italy, from 2008 through 2014. We found that the total cost of a single hospitalization, including hospital stay, surgical intervention, personnel, drugs, and administrative costs ranged from €5,874 to 23,077 (median €11,033) per patient. Our findings confirm that surgery can be an expensive option. Therefore, surgical intervention should be limited to cyst types that do not benefit from nonsurgical therapies and appropriate case management can best be accomplished by using a cyst stage-specific approach.

    Surgical site infection (SSI) is a common and preventable complication of surgery, but the relative importance of individual measures recommended by guidelines has not been determined. Elective general surgical, neurological, and orthopedic procedures requiring antibiotic prophylaxis from a 3-month period were retrospectively studied to determine concordance with SSI prevention guidelines and to identify factors which predicted the development of SSIs. A total of 216 surgeries were reviewed, with 18 SSIs (8.3%). A mean of 1.4 antibiotic prophylaxis errors per surgery were identified, with correct antibiotic type identified for 64%, antibiotic timing for 83%, supplemental antibiotic dosing for 34%, and antibiotic duration of less than 24 h for 44%. Normothermia was present in 79% of surgeries, and normoglycemia was present in 17%. Univariate analysis of the SSI rate identified four significant factors. Antibiotic prophylaxis for less than 24 h postoperatively (odds ratio [OR], 0.213; 95% confidence interval [95% CI]0.060 to 0.757) and neurosurgery (OR, 0.118; 95% CI, 0.15 to 0.903) correlated with a reduced risk of SSI. The mean number of prophylaxis errors (OR, 1.6; 95% CI, 1.02 to 2.4) and a duration of surgical drainage for more than 3 days (OR, 2.679; 95% CI, 1.009 to 7.113) predicted SSI. By multivariate analysis, errors in individual antibiotic prophylaxis measures were not significantly associated with SSI; however, the presence of more than two errors was significant (OR, 4.030; 95% CI, 1.018 to 15.96). A strong correlation was identified between the degree of concordance to SSI prevention guidelines and the SSI rate (P = 0.001, Mantel-Haenszel linear-by-linear association chi-square test).

    The aim was to use a novel functional luminal imaging probe for evaluation of wound defects and tissue damage resulting from the use of trocars. Following general anesthesia of 4 adult pigs, 6 different trocars were randomly inserted at preselected locations in the porcine abdominal wall. The functional luminal imaging probe was used to profile the trocar holes during bag distension from 8 axial cross-sectional area measurements. The cross-sectional areas and pressure in the bag were recorded and exported to Matlab for analysis and data display. Geometric profiles were generated, and the minimum cross-sectional area and hole length (abdominal wall thickness) were used as endpoints. Successful distensions were made in all cases. The slope of the contours increased away from the narrowest point of the hole. The slope increased more rapidly toward the inner abdominal wall than toward the outer wall. The slope of the linear trend lines for the cross-sectional area-pressure relation represents the compliance at the narrowest point in the wall. The hole length (abdominal wall thickness) could be obtained at different cross-sectional area cutoff points. A cutoff point of 300 mm(2) gave good results when compared to the length of the hole measured after the tissue was excised. This technique represents a new and straightforward way to evaluate the effects of trocars on the abdominal wall. It may also prove useful in comparing techniques and technology from different manufacturers. PMID:18757380

    Importance Surgical site infections remain one of the most frequent complications following abdominal surgery and cause substantial costs, morbidity and mortality. Objective To assess the effectiveness of wound edge protectors in open abdominal surgery in reducing surgical site infections. Evidence Review A systematic literature search was conducted according to a prespecified review protocol in a variety of data-bases combined with hand-searches for randomized controlled trials on wound edge protectors in patients undergoing laparotomy. A qualitative and quantitative analysis of included trials was conducted. Findings We identified 16 randomized controlled trials including 3695 patients investigating wound edge protectors published between 1972 and 2014. Critical appraisal uncovered a number of methodological flaws, predominantly in the older trials. Wound edge protectors significantly reduced the rate of surgical site infections (risk ratio 0.65; 95%CI, 0.51–0.83; p = 0.0007; I2 = 52%). The results were robust in a number of sensitivity analyses. A similar effect size was found in the subgroup of patients undergoing colorectal surgery (risk ratio 0.65; 95%CI, 0.44–0.97; p = 0.04; I2 = 56%). Of the two common types of wound protectors double ring devices were found to exhibit a greater protective effect (risk ratio 0.29; 95%CI, 0.15–0.55) than single-ring devices (risk ratio 0.71; 95%CI, 0.54–0.92), but this might largely be due to the lower quality of available data for double-ring devices. Exploratory subgroup analyses for the degree of contamination showed a larger protective effect in contaminated cases (0.44; 95%CI, 0.28–0.67; p = 0.0002, I2 = 23%) than in clean-contaminated surgeries (0.72, 95%CI, 0.57–0.91; p = 0.005; I2 = 46%) and a strong effect on the reduction of superficial surgical site infections (risk ratio 0.45; 95%CI, 0.24–0.82; p = 0.001; I2 = 72%).

    The economic aspects of abdominal wall reconstruction are frequently overlooked, although understandings of the financial implications are essential in providing cost-efficient health care. Ventral hernia repairs are frequently performed surgical procedures with significant economic ramifications for employers, insurers, providers, and patients because of the volume of procedures, complication rates, the significant rate of recurrence, and escalating costs. Because biological mesh materials add significant expense to the costs of treating complex abdominal wall hernias, the role of such costly materials needs to be better defined to ensure the most cost-efficient and effective treatments for ventral abdominal wall hernias.

    We describe a unique case of intra-abdominal textiloma (granuloma due to a retained foreign body), which mimicked a gastric tumor on preoperative imaging studies. A 78-year-old asymptomatic patient with a past history of a gastrectomy was referred for evaluation of an intra-abdominal mass lesion, which was incidentally observed on a computed tomography (CT) scan. Repeated CT with a higher resolution demonstrated a 5-cm heterogeneously enhanced mass with a distinct feeding artery. These findings were all compatible with a tumorous lesion originating in the gastric remnant, most likely gastric gastrointestinal stromal tumor. A diagnosis of textiloma was immediately made during surgery, and it was confirmed pathologically postoperatively. The feeding artery that appeared on CT images, which was a major reason for the false diagnosis, was considered to have resulted from a slow but continuous inflammation reaction around the retained surgical sponge. Surgeons should therefore always take the possibility of textilomas into consideration even with typical tumorous characteristics on preoperative imaging studies, especially in patients with a history of prior abdominal surgery.

    The general indications, timing, and choice of procedure can be determined by asking and answering the following questions appropriately: 1. Has the patient achieved neurologic, emotional, and social stability? 2. What is the patient's current level of motor and sensory resources and function? The number and strength of muscles remaining under good voluntary control are the most important variables. 3. Are the patient's expectations realistic? 4. Does the patient possess the necessary intelligence and motivation? Some procedures, such as arthrodesis of a specific joint, require little motivation to succeed; however, a complex set of muscle-tendon transfers requires a great deal of motor reeducation for the patient to achieve an optimal result. 5. Does the patient have the necessary time to invest in achieving a good result? The patient must be able to set aside the time necessary for postoperative immobilization in a cast or splint and for therapy and reeducation. 6. Are the necessary support services and personnel available and committed? 7. Have all preoperative obstacles to success been considered and has a plan developed to overcome any remaining obstacles? 8. Does the patient understand the potential complications and benefits? 9. Can the patient and professional team tolerate a complication, failure, or suboptimal result? Both the medical staff and the patient must be prepared for complications that may lead to a suboptimal outcome or frank failure. 10. Are the patient's current health and well-being ideal? 11. Is the surgical plan consistent with the patient's physical resources, goals, and expectations? 12. Does an alternate plan exist? 13. Does the surgeon understand the scope of the complications and how to salvage an acceptable result should a complication occur? PMID:12474600

    Implant dentistry has been established as a predictable treatment with excellent clinical success to replace missing or nonrestorable teeth. A successful esthetic implant reconstruction is predicated on two fundamental components: the reproduction of the natural tooth characteristics on the implant crown and the establishment of soft tissue housing that will simulate a healthy periodontium. In order for an implant to optimally rehabilitate esthetics, the peri-implant soft tissues must be preserved and/or augmented by means of periodontal surgical procedures. Clinicians who practice implant dentistry should strive to achieve an esthetically successful outcome beyond just osseointegration. Knowledge of a variety of available techniques and proper treatment planning enables the clinician to meet the ever-increasing esthetic demands as requested by patients. The purpose of this paper is to enhance the implant surgeon's rationale and techniques beyond that of simply placing a functional restoration in an edentulous site to a level whereby an implant-supported restoration is placed in reconstructed soft tissue, so the site is indiscernible from a natural tooth.

    OBJECTIVE To explore whether surgical teams with greater stability among their members (ie, members have worked together more in the past) experience lower rates of sharps-related percutaneous blood and body fluid exposures (BBFE) during surgical procedures. DESIGN A 10-year retrospective cohort study. SETTING A single large academic teaching hospital. PARTICIPANTS Surgical teams participating in surgical procedures (n=333,073) performed during 2001-2010 and 2,113 reported percutaneous BBFE were analyzed. METHODS A social network measure (referred to as the team stability index) was used to quantify the extent to which surgical team members worked together in the previous 6 months. Poisson regression was used to examine the effect of team stability on the risk of BBFE while controlling for procedure characteristics and accounting for procedure duration. Separate regression models were generated for percutaneous BBFE involving suture needles and those involving other surgical devices. RESULTS The team stability index was associated with the risk of percutaneous BBFE (adjusted rate ratio, 0.93 [95% CI, 0.88-0.97]). However, the association was stronger for percutaneous BBFE involving devices other than suture needles (adjusted rate ratio, 0.92 [95% CI, 0.85-0.99]) than for exposures involving suture needles (0.96 [0.88-1.04]). CONCLUSIONS Greater team stability may reduce the risk of percutaneous BBFE during surgical procedures, particularly for exposures involving devices other than suture needles. Additional research should be conducted on the basis of primary data gathered specifically to measure qualities of relationships among surgical team personnel.

    Objectives To describe the surgical and pathologic findings of fertility-sparing radical abdominal trachelectomy using a standardized surgical technique, and report the rate of post-trachelectomy adjuvant therapy that results in permanent sterility Methods A prospectively maintained database of all patients with FIGO stage IB1 cervical cancer admitted to the operating room for planned fertility-sparing radical abdominal trachelectomy was analyzed. Sentinel node mapping was performed via cervical injection of Technetium and blue dye. Results Between 6/2005 and 5/2008, 22 consecutive patients with FIGO stage IB1 cervical cancer underwent laparotomy for planned fertility-sparing radical abdominal trachelectomy. Median age was 33 years (range 23–43). Histology included 13 (59%) with adenocarcinoma and 9 (41%) with squamous carcinoma. Lymph-vascular invasion was seen in 9 (41%) cases. Only 3 (14%) needed immediate completion radical hysterectomy due to intraoperative findings (2 for positive nodes, 1 for positive endocervical margin). Median number of nodes evaluated was 23 (range 11–44); and 6 (27%) patients had positive pelvic nodes on final pathology – all received postoperative chemoradiation. Sixteen (73%) patients agreed to participate in sentinel node mapping which yielded a detection rate of 100%, sensitivity of 83%, specificity of 100% and false negative rate of 17%. Eighteen of 19 (95%) patients who completed trachelectomy had a cerclage placed, and 9/22 (41%) patients had no residual cervical carcinoma on final pathology. Median time in the operating room was 298 minutes (range 180–425). Median estimated blood loss was 250 ml (range 50–700), and median hospital stay was 4 days (range 3–6). No recurrences were noted at the time of this report. Conclusions Cervical adenocarcinoma and lymph-vascular invasion are common features of patients selected for radical abdominal trachelectomy. The majority of patients can undergo the operation successfully

    The time (interval, postpartum, postabortum), location (uterus, mucus membrane of the oviducts, tubes), access (transcervical, transvaginal, trans-abdominal) and the actual method of sterilization for the women (surgical, electric, thermic, mechanical) can be differentiated and combined with each other in various ways. Today the usual procedure is sterilization by partial resection of the oviducts performed laparoscopically in the interval via electrocoagulation and surgically after delivery via periumbilical minilaparotomy. Laparoscopic sterilization via electrocoagulation has a rate of failure of about 1:1,000 and the mortality rate is less than 1:10,000. The most frequent complications are: hemorrhages due to injury of the larger vessels and burns in the intestine caused by the electric current. For this reason, conventional (:unipolar") electrocoagulation should be replaced by the so-called bipolar coagulation or other newer methods which avoid these complications. On the basis of the current literature, no definitive statements can be made regarding the reliability of the newer methods (silastic ring, plastic clips, thermocoagulation). An additional, although up until now purely hypothetic, advantage of the newer methods is the possibility of reversibility. With conventional electrocoagulation, the rate of reversilbility is very low. Additional alternatives are also culdotomy and minilaparotomy in the interval with the assistance of a uterus elevator. Both ways of access may be combined with various methods of sterilization. The pros and cons of the hysterectomy as a method of sterilization are still being discussed. Occasional late sequelae of sterilization such as menstrual disorders, pain and, particularly, problems related to sexual intercourse have only recently come to light. They have not yet been adequately investigated. PMID:131732

    2009-01-01

    Introduction Critically ill surgical patients frequently develop intra-abdominal hypertension (IAH) leading to abdominal compartment syndrome (ACS) with subsequent high mortality. We compared two temporary abdominal closure systems (Bogota bag and vacuum-assisted closure (VAC) device) in intra-abdominal pressure (IAP) control. Methods This prospective study with a historical control included 66 patients admitted to a medical and surgical intensive care unit (ICU) of a tertiary care referral center (Careggi Hospital, Florence, Italy) from January 2006 to April 2009. The control group included patients consecutively treated with the Bogota bag (Jan 2006-Oct 2007), whereas the prospective group was comprised of patients treated with a VAC. All patients underwent abdominal decompressive surgery. Groups were compared based upon their IAP, SOFA score, serial arterial lactates, the duration of having their abdomen open, the need for mechanical ventilation (MV) along with length of ICU and hospital stay and mortality. Data were collected from the time of abdominal decompression until the end of pressure monitoring. Results The Bogota and VAC groups were similar with regards to demography, admission diagnosis, severity of illness, and IAH grading. The VAC system was more effective in controlling IAP (P < 0.01) and normalizing serum lactates (P < 0.001) as compared to the Bogota bag during the first 24 hours after surgical decompression. There was no significant difference between the SOFA scores. When compared to the Bogota, the VAC group had a faster abdominal closure time (4.4 vs 6.6 days, P = 0.025), shorter duration of MV (7.1 vs 9.9 days, P = 0.039), decreased ICU length of stay (LOS) (13.3 vs 19.2 days, P = 0.024) and hospital LOS (28.5 vs 34.9 days; P = 0.019). Mortality rate did not differ significantly between the two groups. Conclusions Patients with abdominal compartment syndrome who were treated with VAC decompression had a faster abdominal closure rate and

    Background Hereditary angioedema (HAE), caused by deficiency in C1-inhibitor (C1-INH), leads to unpredictable edema of subcutaneous tissues with potentially fatal complications. As surgery can be a trigger for edema episodes, current guidelines recommend preoperative prophylaxis with C1-INH or attenuated androgens in patients with HAE undergoing surgery. However, the risk of an HAE attack in patients without prophylaxis has not been quantified. Objectives This analysis examined rates of perioperative edema in patients with HAE not receiving prophylaxis. Methods This was a retrospective analysis of records of randomly selected patients with HAE type I or II treated at the Frankfurt Comprehensive Care Centre. These were examined for information about surgical procedures and the presence of perioperative angioedema. Results A total of 331 patients were included; 247 underwent 700 invasive procedures. Of these procedures, 335 were conducted in 144 patients who had not received prophylaxis at the time of surgery. Categories representing significant numbers of procedures were abdominal (n = 113), ENT (n = 71), and gynecological (n = 58) procedures. The rate of documented angioedema without prophylaxis across all procedures was 5.7%; in 24.8% of procedures, the presence of perioperative angioedema could not be excluded, leading to a maximum potential risk of 30.5%. Predictors of perioperative angioedema could not be identified. Conclusion The risk of perioperative angioedema in patients with HAE type I or II without prophylaxis undergoing surgical procedures ranged from 5.7% to 30.5% (CI 3.5–35.7%). The unpredictability of HAE episodes supports current international treatment recommendations to consider short-term prophylaxis for all HAE patients undergoing surgery. PMID:23968383

A 60-year-old man was diagnosed as having a ruptured abdominal aortic aneurysm (AAA) and an aortocaval fistula, by enhanced computed tomography (CT). After the aneurysm had been opened, the fistula was detected, but there was no bleeding because it was covered with clot. After graft repair, bleeding from the fistula occurred when the clot was removed by suction. Direct closure of the fistula was achieved after bleeding was controlled by digital compression.

    Background: Surgical treatment of a ruptured abdominal aorta aneurysm (RAAA) continues to present a significant challenge to surgeons. There are some patient factors such as age and gender that cannot be changed, and comorbid conditions can be optimized but not eliminated. The purpose of this study was to identify the risk factors affecting high mortality after the surgical repair of an RAAA. Methods: Data on 121 patients who underwent surgical repair for RAAAs between January 1997 and June 2011 in our institution were collected retrospectively. All the patients had been diagnosed by computed tomography (CT) scans, and intraoperative extra-luminal blood was visualized intraoperatively. Variables studied comprised demographic data; preoperative, operative, and postoperative data; and the causes of mortality. Multivariate regression analysis was used to determine the predictors of mortality. Results: One hundred eight (89.2%) patients were male and 13 (10.7%) were female at an average age of 68.9 ± 10.5 years. Totally, 121 patients underwent surgery for RAAAs. Fifty-four patients had aortic tube grafts, 32 aortobiiliac grafts, 20 aortobifemoral grafts, 1 aortoiliac graft, and 1 aortofemoral graft for the replacement of the RAAAs. Seven patients had only surgical exploration. Operative mortality was 41.3% (50 patients). The factors associated with mortality were preoperative shock, free blood, positive inotropic agent, hematocrit value, and need for blood and plasma. In the multivariate analysis, preoperative shock and positive inotropic agents were found to be significant as the predictors of death (OR: 19.8, 95%CI: 3.2-122.8 and OR: 8.6, 95% CI: 2.9-26.3, respectively). Conclusion: This study revealed that the preoperative clinical findings affected the mortality associated with RAAAs. PMID:26697083

    Biotelemetry is a useful tool to monitor the movements of animals and is widely applied in fisheries research. Radio or acoustic technology can be used, depending on the study design and the environmental conditions in the study area. A broad definition of telemetry also includes the use of Passive Integrated Transponder (PIT) tags, either separately or with a radio or acoustic transmitter. To use telemetry, fish must be equipped with a transmitter. Although there are several attachment procedures available, surgical implantation of transmitters in the abdominal cavity is recognized as the best technique for long-term telemetry studies in general (Stasko and Pincock, 1977; Winter, 1996; Jepsen, 2003), and specifically for juvenile salmonids, Oncorhynchus spp. (Adams and others, 1998a, 1998b; Martinelli and others, 1998; Hall and others, 2009). Studies that use telemetry assume that the processes by which the animals are captured, handled, and tagged, as well as the act of carrying the transmitter, will have minimal effect on their behavior and performance. This assumption, commonly stated as a lack of transmitter effects, must be valid if telemetry studies are to describe accurately the movements and behavior of an entire population of interest, rather than the subset of that population that carries transmitters. This document describes a standard operating procedure (SOP) for surgical implantation of radio or acoustic transmitters in juvenile salmonids. The procedures were developed from a broad base of published information, laboratory experiments, and practical experience in tagging thousands of fish for numerous studies of juvenile salmon movements near Columbia River and Snake River hydroelectric dams. Staff from the Western Fisheries Research Center's Columbia River Research Laboratory (CRRL) frequently have used telemetry studies to evaluate new structures or operations at hydroelectric dams in the Columbia River Basin, and these evaluations typically

    Hysterectomy is the most common major gynecologic procedure. Although alternatives to hysterectomy result in fewer procedures performed annually, and the use of endoscopic techniques and vaginal hysterectomy have resulted in a lower percentage performed by the open abdominal route, certain pelvic disorders require abdominal hysterectomy. Preoperative evaluation with informed consent and surgical planning are essential to select appropriate candidates. Prophylactic antibiotics, thromboprophylaxis, attention to surgical technique, and enhanced recovery protocols should be used to provide optimal outcomes. PMID:27521877

    CT of the abdomen and pelvis is the first line imaging modality for staging, selecting treatment options and assessing disease response in ovarian cancer. The staging CT provides disease distribution, disease burden and is the imaging surrogate for surgico-pathological FIGO staging. Optimal cyto-reductive surgery offers patients' the best chance for disease control or cure, but sub-optimal resection confers no advantage over chemotherapy and adversely increases the risk of post surgical complications. Although there is extensive literature comparing performance of CT against laparoscopy and surgery, for the staging abdominal and pelvic CT, there are currently no accepted guidelines for interpretation or routinely used minimum data set templates for reporting these complex CT scans often with extensive radiological findings. This review provides a systematic approach for identifying the important radiological findings and highlighting important sites of disease within the abdomen and pelvis, which may alter or preclude surgery at presentation or after adjuvant chemotherapy. The distribution of sites and volume of disease can be used to categorize patients as suitable, probably suitable or not suitable for optimal cyto-reductive surgery. This categorization can potentially assist oncological surgeons and oncologists as a semi objective assessment tool useful for selecting patient treatment, streamlining multi disciplinary discussion and improving the reproducibility and correlation of CT with surgical findings. The review also highlights sites of disease and complications of ovarian cancer which should be included as part of the radiological report as these may require additional surgical input from non gynaecological surgeons or influence treatment selection.

    A technique for assessing the immediate and prolonged efficacy of surgical scrubs and alcoholic hand rubs is described. A mean baseline count is obtained from all volunteers and logarithmic reductions in resident skin flora immediately after one or more applications, and after wearing gloves for 3 h, are measured. Loose-fitting surgical gloves are used for sampling resident flora. Preparations were applied using a standard technique for 2 min, apart from one test with 70% isopropanol (IPA) in which the application time was 30 s. Two studies are described, one of which compared four chlorhexidine scrubs, and the second 70% IPA, 7.5% povidone-iodine scrub, 2% triclosan cleanser and unmedicated bar soap. In spite of their constituent similarity, the four chlorhexidine scrubs varied considerably in efficacy and user acceptability. A 2 min application of 70% IPA was the most effective treatment, and gave log10 reductions of 1.65 for immediate and 1.58 for prolonged effect. This was marginally more effective than a 30 s application, but the difference was not significant. 'Hibiscrub' was the most effective aqueous formulation and gave reductions of 1.01 for immediate effect and 1.16 for prolonged effect. The test described could be used by reference centres and manufacturers to assess the efficacy of new and existing surgical hand disinfection formulations. PMID:1679446

    Radiotelemetry is an essential tool in the study of free-ranging bird populations, and a variety of transmitter-attachment methods have been developed. A promising new method is abdominal implantation of a transmitter with a percutaneous antenna. Researchers using this technique should be concerned about and aware of mortality during surgery and during the immediate postrelease period (the 14-day period following surgery). Of 307 radio-implant surgeries performed between 1995 and 1997 in harlequin ducks (Histrionicus histrionicus), 7 (2.3%) deaths were documented during surgery or anesthetic recovery. Of 295 birds released with implanted radios, 10 (3.4%) died during the immediate postrelease period. Modifications to anesthetic procedures used in the 204 surgeries performed in 1996 and 1997 reduced mortality to 1.5% during surgery and 1.5% during the immediate postrelease period. Anesthetic modifications included intubation of all birds, placement of birds on an elevated platform that allowed the head to rest at a level lower than the body during surgery, placement of a heated water blanket under the birds during surgery, monitoring of body temperature, and use of electrocardiogram and Doppler ultrasound to monitor heart rates and arrhythmias. Low levels of mortality associated with abdominal implantation of radio transmitters may be unavoidable, but mortality can be minimized with adjustments to anesthetic technique.

    In the past, rudimentary devices were used to record surgical operations. Currently, the introduction of technologic advances such as high-definition television and the miniaturization of high-resolution digital video cameras provides an opportunity for making significantly enhanced surgical records. These enhancements, coupled with the recent advances in telemedicine and surgical simulation, will improve cardiac surgery training and skill acquisition, decrease operative times and costs, minimize morbidity, and improve overall patient care. The present paper provides a discussion of the media technology offered to surgeons for recording a surgical procedure on video. Hardware technology, including different types of cameras and analogical or digital post processing methods, are reviewed with a surgical ''eye''. This ''how to'' paper provides practical suggestions to surgeons in order to enhance surgical video recording. PMID:18670389

    Surgical excision of fibrotic plaques and replacement of the defect by grafts may be necessary in advanced Peyronie disease. Synthetic, absorbable mesh for grafting the defect was used in 6 mongrel dogs. An area of tunica albuginea 1.5 by 2.5 cm was removed from the corpus cavernosum, thus exposing the spongy cavernous tissue. A Dexon mesh of the same dimensions, woven in our laboratory from polyglycolic acid fibers of 308 denier thickness, was sutured to the defect by 3-0 Dexon sutures. The mesh caused hemostasis and the animals' postoperative course was uneventful. Posterection cavernosograms showed no curvature of the penis, bulging of the operative area, or obstruction of the corpora cavernosa. Histologic studies at three weeks, and two, four, and six months after surgery showed complete healing and gradual replacement of the Dexon mesh by fibrous connective tissue. PMID:6304969

    Background The purpose of this study was to examine the volume and variability of non-cardiac surgeries performed in children with congenital heart disease (CHD) requiring cardiac surgery in the first year of life. Methods Patients who underwent cardiac surgery by 1 year of age and had a minimum 5-year follow-up at 22 of the hospitals contributing to the Pediatric Health Information System database between 2004–2012 were included. Frequencies of non-cardiac surgical procedures by age 5 years were determined and categorized by subspecialty. Patients were stratified according to their maximum RACHS-1 (Risk Adjustment in Congenital Heart Surgery) category. The proportions of patients across hospitals who had a non-cardiac surgical procedure for each subspecialty were compared using logistic mixed effects models. Results 8,857 patients underwent congenital heart surgery during the first year of life, 3,621 (41%) of whom had 13,894 non-cardiac surgical procedures by 5 years. Over half of all procedures were in general surgery (4,432; 31.9%) or otolaryngology (4,002; 28.8%). There was significant variation among hospitals in the proportion of CHD patients having non-cardiac surgical procedures. Compared to children in the low risk group (RACHS-1 categories 1–3), children in the high-risk group (categories 4–6) were more likely to have general, dental, orthopedic, and thoracic procedures. Conclusions Children with CHD requiring cardiac surgery frequently also undergo non-cardiac surgical procedures; however, considerable variability in the frequency of these procedures exists across hospitals. This suggests a lack of uniformity in indications used for surgical intervention. Further research should aim to better standardize care for this complex patient population. PMID:25475794

    Postoperative acute urinary retention was evaluated in the patients who underwent Pereyra procedure. Comparison of suprapubic and urethral catheterization. Between January 1994 and July 1995, fifty two patients with urinary stress incontinence underwent Pereyra procedure, 31 female patient with suprapubic drainage (cistofix Ch 15) and 17 urethral catherization with a latex foley catheter. Sponatneous micturition and urinary retention was evaluated until the catheter was removed. Mean age was 43.8 years (32 a 66), the duration of suprapubic vesical drainage with suprapubic catheter were 3 days in 58.6% of the patients, and more than 3 days in 41.29%. Recatheterizacion in the patients with urethral drainage was more frequent. Urinary retention after 7 days was present in 23.99% with suprapubic vesical drainage and 28.5% with urethral catheter. Recatheterization is more frequent in patients with urethral catheter. PMID:8756195

    Purpose The use of abdominal computed tomography (ACT) utilization is increasing to a remarkable extent in the pediatric Emergency Department (ED), but the clinical benefit of increased use of ACT for pediatric surgical patients remains uncertain. Methods A retrospective review was conducted to investigate if, for patients who had visited pediatric ED during the last 5 years, increasing utilization of ACT would increase the detection rate of acute appendicitis, increase the detection rate of surgical conditions other than appendicitis, and decrease the hospital admission rate for surgical conditions. Results During the study period, there were 37,918 ED visits; of these, 3,274 (8.6%) were for abdominal pain, 844 (2.2%) had ACT performed. The annual proportional increase of the ACT was statistically significant (1.56% to 2.46%, P = 0.00), but the detection rate of acute appendicitis (3.3% to 5.1%) or other surgical conditions (1.7% to 2.8%) showed no statistically significant changes. Hospital admission rates (5.6% to 6.8%) also showed no significant changes during the study period. Conclusion Increasing utilization of ACT does not lead to the improved outcomes in caring for pediatric surgical patients visiting the pediatric ED. Careful evaluation for the indication for ACT is needed in the pediatric ED. PMID:25368849

    No consensus exists regarding the precise role of testicular biopsy in prepubertal boys, although it is considered useful for assessing the potential consequences of undescended testes on fertility. Current scientific knowledge indicates that surgeons should broaden indications for this procedure. For example, the use of immunohistochemical markers such as OCT/3-4, TSPY, Kit ligand (SCF) and ALPP (PLAP) has considerably facilitated the detection of germ cell tumour precursors, such as carcinoma in situ and/or gonadoblastoma. These markers are very important for evaluating malignancy risk in undervirilized patients with 46,XY disorders of sexual development. Testicular histology is also of considerable value in the prediction of both fertility potential and risk of cancer in individuals with undescended testes, particularly those with intraabdominal undescended testes. New possibilities for the preservation of fertility after gonadotoxic chemotherapy - even for prepubertal boys - are emerging. Cryopreservation of testicular tissue samples for the preservation of fertility - although still an experimental method at present - is appealing in this context. In our opinion, testicular biopsy in prepubertal boys is a minor procedure that can provide valuable information for predicting the risk of malignancy and fertility, and might be useful in fertility preservation in the near future.

    Neoplastic disease is common in pet birds, particularly in psittacines, and treatment should be primarily aimed at tumor eradication. Nineteen cases of pet birds submitted to diagnostic and/or therapeutic surgical procedures due to neoplastic disease characterized by the presence of visible masses were retrospectively analyzed; affected species, types of neoplasms and respective locations, and outcomes of surgical procedures were determined. All birds undergoing surgery belonged to the order Psittaciformes; the Blue-fronted parrot (Amazona aestiva) was the prevalent species. Lipoma was the most frequent neoplasm in the sample studied. Most neoplasms affected the integumentary system, particularly the pericloacal area. Tumor resection was the most common surgical procedure performed, with high resolution and low recurrence rates.

    Introduction: Inferior oblique overaction (IOOA) can be primary or secondary, isolated or combined to other types of horizontal deviation, mostly with esotropias. Surgical weakening of IOOA means several techniques like; recession, myotomy, myectomy, anteroposition etc. Goals: we analyzed the effect of inferior oblique muscle surgical weakening comparing two groups of patients with primary hypertropia. Material and methods: In 5-years retrospective study, we observed 33 patients on which we did the surgical procedure of weakening inferior muscle overaction by two methods; recession and myotomy. Results: In total number of 33 patients, there were 57,6% male and 42,4% female patients with average age of 10,6±7,5 (in range of 4–36). There was 33,3% of isolated primary hypertropias, and 66,7% combined with esotropias. At 23 (69,9%) patients the recession surgical procedure was done, and with 10 (30,1%) myotomy. Better effect and binocularity was in 65,2% of patients in recession group which was statistically significant with significance level of p<0,0, χ2=5,705; p=0,021. Conclusion: Comparing of two surgical procedures of weakening inferior oblique muscles overaction, recession is better procedure than myotomy. PMID:26261384

    In recent years, the live broadcasting of medical and surgical procedures has gained worldwide popularity. While the practice has appropriately been met with concerns for patient safety and privacy, many physicians tout the merits of real time viewing as a form of investigation, accelerating the process leading to adoption or abolition of newer techniques or technologies. This view introduces a new series of ethical considerations that need to be addressed. As such, this article considers, from a research ethics perspective, the use of live surgical procedure broadcast for investigative purposes. PMID:21292217

  8. Microporous polysaccharide hemosphere absorbable hemostat use in cardiothoracic surgical procedures

    2014-01-01

    Background Topical hemostatic agents are used to reduce bleeding and transfusion need during cardiothoracic surgery. We report our experience with Arista® AH Absorbable Hemostatic Particles (Arista® AH), a novel plant-based microporous polysaccharide hemostatic powder. Methods Data were retrospectively collected for patients (n = 240) that received cardiothoracic surgery at our institution from January 2009 to January 2013 with (n = 103) or without (n = 137) the use of Arista® AH. Endpoints included protamine to skin closure time (hemostasis time), cardiopulmonary bypass time, quantity of Arista® AH applied, intraoperative blood product usage, intraoperative blood loss, chest tube output 48 hours postoperatively, blood products required 48 hours postoperatively, length of stay in the intensive care unit, 30-day morbidity, and 30-day mortality. Results 240 patients (176 M: 64 F) underwent 240 cardiothoracic procedures including heart transplantation (n = 53), cardiac assist devices (n = 113), coronary artery bypass grafts (n = 20), valve procedures (n = 19), lung transplantation (n = 17), aortic dissection (n = 8), and other (n = 10). Application of Arista® AH led to significant reduction in hemostasis time versus the untreated control group (Arista® AH: 93.4 ± 41 min. vs. Control: 107.6 ± 56 min., p = 0.02). Postoperative chest tube output in the first 48 hours was also significantly reduced (Arista® AH: 1594 ± 949 mL vs. Control: 2112 ± 1437 mL, p < 0.001), as well as transfusion of packed red blood cells (Arista® AH: 2.4 ± 2.5 units vs. Control: 4.0 ± 5.1 units, p < 0.001). There was no significant difference in 30-day mortality or postoperative complications. Conclusion Use of Arista® AH in complex cardiothoracic surgery resulted in a significant reduction in hemostasis time, postoperative chest tube output, and need for postoperative blood transfusion.

    OBJECTIVE. We explore the contribution of income and ethnicity to geographic variation in utilization of surgical procedures. DATA SOURCES/STUDY SETTING. We assessed the use of eight procedures from 1986 through 1988 among residents of Los Angeles County using data from the California Discharge Dataset, the 1980 census, and other secondary sources. Procedures chosen for evaluation were coronary artery bypass grafting (CABG), coronary artery angioplasty, permanent pacemaker insertion, mastectomy, simple hysterectomy, transurethral prostate resection (TURP), carotid endarterectomy, and appendectomy. STUDY DESIGN. The amount of inter-zip code variation for each procedure was first measured using various estimates including the analysis of variance coefficient of variation (CVA). Population-weighted multivariate regression analysis was used to model variation in age- and gender-adjusted rates of procedure use among 236 residential zip codes. PRINCIPAL FINDINGS. Highest-variation procedures were coronary artery angioplasty (CVA = .392) and carotid endarterectomy (CVA = .374). The procedures with the lowest degree of variation were cardiac pacemaker implantation (CVA = .194) and hysterectomy (CVA = .195). Variation was significantly related to income (carotid endarterectomy) and either African American or Latino zip code ethnicity for all procedures except pacemaker implantation. For all procedures except appendectomy, the direction of the effect was toward fewer procedures with lower income. However, the effect of African American or Latino population ethnicity varied. CONCLUSIONS. In this large urban area both population ethnicity and socioeconomic status are significantly associated with the geographic utilization of selected surgical procedures. PMID:7721583

    Goniotomy is an effective treatment for primary infantile glaucoma. Unlike trabeculotomy, goniotomy facilitates the visualization of the trabecular meshwork and does not disturb the conjunctiva. Because a cloudy cornea may prevent a clear view of the anterior chamber angle through the operating microscope, we investigated whether an endoscope would improve visualization during goniotomy in pig cadaver eyes. We deepened the anterior chamber of each pig eye with viscoelastic material. A modified 23-gauge needle attached to an Olympus 0.8 mm diameter flexible fiberoptic endoscope entered the anterior chamber through a 3 mm limbal incision. The angle was clearly seen on a videoscreen as the needle approached and incised the trabecular pillars for 120 degree(s); the iris immediately fell back. Following the procedure, the eyes were fixed in formalin and sectioned for light microscopy, or fixed in 2% glutaraldehyde for scanning electron microscopy. Trabecular pillars were present from the iris root to Schwalbe's line in the untreated region of the anterior chamber angle. The treated area demonstrated incision of the trabecular pillars with opening of the underlying trabecular meshwork.

    Neuropsychological and neuropsychiatric disorders following open heart surgery are estimated to occur in as many as 80 per cent of all patients. They have been recognised from the very beginning of modern heart surgery. Despite a huge amount of scientific literature, data concerning incidence, the phenomenology and duration of symptoms diverge. This finding may be explained by heterogeneous aetiopathogenetic concepts and methodological and terminological problems associated with the investigation of postoperative delirium or neuropsychological and psychopathological sequelae of cardiac surgery. Nowadays, most authors agree in respect of a multifactorial pathogenesis of cognitive deficits following cardiac surgery. Factors influencing the psychopathological and neuropsychological outcome of cardiac surgery can be divided into pre-, intra- and postoperative variables. Advanced age, degree of cardiovascular impairment and other case histories, as well as history of drug abuse, are those preoperative variables that may be responsible for a postoperative cognitive decline. The predictive value of personality traits (depression and/or anxiety), however, is most controversial. Among the intraoperative variables related to the postoperative cognitive state, are e.g. the type of operation and technical procedure (micro-/macroembolism due to the way of oxygenation, pulsatile/-non-pulsatile flow) and duration of extracorporeal circulation. In the postoperative period, the duration of intubation or ICU stay and related variables (like sleep or sensory deprivation/hyperstimulation) were identified as significant predictors of neuropsychological and psychopathological alterations. Modern research focusses on neurobiochemical markers of brain injury which may serve as early predictors of a postoperative cognitive decrease. These parameters may indicate an early postoperative diagnosis and neuroprotective treatment in patients at risk. PMID:9512983

    OBJECTIVE To determine the effect of arthrotomy alone or in combination with osteotomy of the proximal portion of the tibia on blood delivery to the patellar tendon of dogs. SAMPLE 24 canine cadavers. PROCEDURES One hind limb from each cadaver was assigned to 1 of 4 treatment groups: medial arthrotomy (MA; MA group), lateral arthrotomy (LA; LA group), MA and LA with tibial tuberosity transposition (MALA group), and MA with tibial plateau leveling osteotomy (TPLO; TPLO group). The contralateral hind limb served as the control sample. Contrast solution (barium [33%], India ink [17%], and saline [0.9% NaCl] solution [50%]) was injected through an 8F catheter inserted in the caudal portion of the abdominal aorta. Limbs were radiographed to allow examination of vascular filling. The patella, patellar tendon, and tibial crest were harvested, radiographed to allow examination of tissue vascular filling, and fixed in 4% paraformaldehyde. Vessels perfused with contrast solution were counted in sections obtained from the proximal, middle, and distal regions of each patellar tendon. RESULTS Vessel counts did not differ significantly among the 3 tendon regions. Compared with results for the control group, delivery of contrast solution to the patellar tendon was significantly decreased in the MALA and TPLO groups but was not changed in the MA or LA groups. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that surgical procedures used to treat cranial cruciate injuries (ie, TPLO) and patellar luxation decreased blood delivery to the patellar tendon of canine cadavers, at least acutely.

    This study aimed to assess patient entrance surface air kerma (ESAK) during chest and abdominal X-ray procedures in screen film radiography (SFR) and computed radiography (CR) to establish dose reference levels. Patients' doses were measured in five hospitals for a total of 196 patients. ESAK was calculated from exposure parameters using DosCal software. The X-ray tube output (mGy mAs(-1)), accuracy of exposure factors, linearity and reproducibility were measured using an Unfors Xi dosimeter. The overall mean and range of ESAK during chest X-ray were 0.6 ± 0.3 (0.1-1.3) mGy, while for abdominal X-rays they were 4.0 ± 3.2 (1.3-9.2) mGy. Hospital with a CR system was found to use relatively higher doses. Dose values for abdominal X-ray procedures were comparable with previous studies. The dose for chest X-ray procedure was higher by a factor of 2-3 compared with the current international reference levels. PMID:25852182

    The laryngeal mask airway (LMA) is a supraglottic airway management device. The LMA is preferred for airway management in paediatric patients for short duration surgical procedures. The recently introduced ProSeal (PLMA), a modification of Classic LMA, has a gastric drainage tube placed lateral to main airway tube which allows the regurgitated gastric contents to bypass the glottis and prevents the pulmonary aspiration. This study was done to compare the efficacy of ProSeal LMA with an endotracheal tube in paediatric patients with respect to number of attempts for placement of devices, haemodynamic responses and perioperative respiratory complications. Sixty children, ASA I and II, weighing 10-20 kg between 2 and 8 years of age group of either sex undergoing elective ophthalmological and lower abdominal surgeries of 30-60 min duration, randomly divided into two groups of 30 patients each were studied. The number of attempts for endotracheal intubation was less than the placement of PLMA. Haemodynamic responses were significantly higher (P<0.05) after endotracheal intubation as compared to the placement of PLMA. There were no significant differences in mean SpO2 (%) and EtCO2 levels recorded at different time intervals between the two groups. The incidence of post-operative respiratory complications cough and bronchospasm was higher after extubation than after removal of PLMA. The incidence of soft tissue trauma was noted to be higher for PLMA after its removal. There were no incidences of aspiration and hoarseness/sore throat in either group. It is concluded that ProSeal LMA can be safely considered as a suitable and effective alternative to endotracheal intubation in paediatric patients for short duration surgical procedures.

    Outpatient surgical procedures for adult hip and knee reconstruction are gaining interest on a worldwide basis and have been progressively increasing over the last few years. Preoperative screening needs to concentrate on both the patient's comorbidities and home environment to provide a proper alignment of expectations of the surgeon, the patient, and the patient's family. Preoperative multidisciplinary patient information covering all aspects of the upcoming treatment course is a mandatory step, focusing on pain management and early mobilization. Perioperative pain management includes both multimodal and preventive analgesia. Preemptive medications, minimization of narcotics, and combination of general and regional anesthesia are the techniques required in joint arthroplasty performed as an outpatient surgical procedure. A multimodal blood loss management program should be used with preoperative identification of anemia and attention directed toward minimizing blood loss, considering the use of tranexamic acid during the surgical procedure. Postoperative care extends from the initial recovery from anesthesia to the physical therapist's evaluation of the patient's ambulatory status. After the patient has met the criteria for discharge and has been discharged on the same day of the surgical procedure, a nurse should call the patient later at home to check on wound status, pain control, and muscle weakness, which will be further addressed by physiotherapy and education. Implementing outpatient arthroplasty requires monitoring safety, patient satisfaction, and economic impact. PMID:27385689

    Recently, many studies have emphasized the importance of the comprehension of detailed functional anatomy of the distal forearm and wrist joint, and their biomechanics. A significant contribution which yields good functional outcomes of surgical treatment was the development of the locking plate technology; this technology has facilitated the improvement of the surgical technique for the fixation of fractures. This article reviews the locking mechanism and design of the fixation screws and plate, and the details of the surgical technique including the double-tired subchondral support procedure as it is applied to common fractures. Arthroscopic-assisted surgical procedures can be used to reduce the intra-articular fracture fragments after realignment of the distal radius with the locking plate. This technique is also useful at the time of fixation to assess soft tissue injury. The combination of arthroscopic-assisted reduction and locking plate fixation is now indicated for AO type C2 and C3 intra-articular comminuted fractures. PMID:27006135

    In order to examine whether thorough surgical hand disinfection (handwashing plus hand disinfection) between consecutive operations is necessary, tests were carried out simulating normal clinical conditions. The tests were performed according to the guidelines for the evaluation of disinfection procedures of the German Society for Hygiene and Microbiology. Surgical hand disinfection was as follows: handwashing with soap without antimicrobial additives and subsequent 5-min disinfection with 60% n-propanol. This was followed by simulated operations of 30 or 120 min duration with a 30-min break between operations, during which half of the test group kept on the surgical gloves, while the other half removed them. The second surgical hand disinfection was done without prior handwashing by 50% of the test group. The disinfection time was reduced from 5 to 1 min by 50% of the test group. The results were evaluated by means of explorative data analysis and inductive statistical methods. Removing the surgical gloves during the interoperative break did not result in significantly higher numbers of colony forming units (cfu) compared with retaining the gloves. This was also the case after a subsequent handwashing. At the second surgical hand disinfection, after a simulated operation of 60 min duration (including break), there was no significant difference in the numbers of cfus between the test group who had washed their hands and those who had not. Reducing the disinfection time from 5 min to 1 min was not associated with a significant increase in the number of cfus. However, after a simulated operating time of 150 min (including the break), the second surgical hand disinfection with handwashing resulted in a significantly lower number of microorganisms than disinfection alone. In half the tests, the numbers of cfu were significantly lower when the test group disinfected their hands for 5 min rather than 1 min. PMID:1684604

    Introduction: The purpose of this study is to compare the efficiency of culture methods in detecting microorganisms appearing in the bloodstream after various oral surgical procedures and effect of preoperative antibiotics and antiseptic rinses on bacteremia. Materials and Methods: The prevalence of bacteremia at various intervals of time (pre- and post-surgical) was studied in three different groups presenting with indications to surgical intervention. Two of the groups were given presurgical prophylaxis (systemic antibiotic and antiseptic rinse) while, in one group, no prophylactic measure was adopted. Blood samples were withdrawn from the subjects at specific pre- and post-surgical time intervals, and microbiological analysis was done. The findings were compared with a control group involving healthy individuals and a group involved in maxillofacial trauma where the breach of oral mucosal integrity was not surgically planned. Results: The presence of bacteremia was not observed in all five groups at baseline while postsurgery (30 min, 60 min, and 90 min) in only three groups (preoperative antibiotic, without prophylaxis, and 1% Povidone iodine rinse). At all postsurgery periods (30 min, 60 min and 90 min), the presence of bacteremia was evident highest in without prophylaxis group followed by 1% Povidone iodine rinse and preoperative antibiotic the least.

    The extensor apparatus is a complex muscle-tendon system that requires integrity or optimal reconstruction to preserve hand function. Anatomical knowledge and the understanding of physiopathology of extensor tendons are essential for an accurate diagnosis of extensor tendon injuries (ETIs) of the hand and wrist, because these lesions are complex and commonly observed in clinical practice. A careful clinical history and assessment still remain the first step for the diagnosis, followed by US and MR to confirm the suspect of ETI or to investigate some doubtful conditions and rule out associate lesions. During last decades the evolution of surgical techniques and rehabilitative treatment protocol led to gradual improvement in clinical results of ETI treatment and surgical repair. Injury classification into anatomical zones and the evaluation of the characteristics of the lesions are considered key points to select the appropriate treatment for ETI. Both conservative and surgical management can be indicated in ETI, depending on the anatomical zone and on the characteristics of the injuries. As a general rule, an attempt of conservative treatment should be performed when the lesion is expected to have favorable result with nonoperative procedure. Many surgical techniques have been proposed over the time and with favorable results if the tendon injury is not underestimated and adequately treated. Despite recent research findings, a lack of evidence-based knowledge is still observed in surgical treatment and postoperative management of ETI. Further clinical and biomechanical investigations would be advisable to clarify this complex issue. PMID:27616821

    Experiments to develop innovative surgical therapy procedures are conventionally conducted on animals, as crucial aspects like tissue removal and bleeding disposition cannot be investigated in vitro. Extracorporeal organ models however reflect these aspects and could thus reduce the use of animals for this purpose fundamentally in the future. The aim of this work was to validate the isolated perfused porcine kidney model with regard to its use for surgical purposes on the basis of histological and radiological procedures. The results show that neither storage nor artificial perfusion led to any structural or functional damage which would affect the quality of the organ. The kidney model is highly suitable for simulating the main aspects of renal physiology and allows a constant calibration of perfusion pressure and tissue temperature. Thus, with only a moderate amount of work involved, the kidney model provides a cheap and readily available alternative to conventional animal experiments; it allows standardised experimental settings and provides valid results.

    Among alveolar ridge augmentation techniques, the ridge-split procedure demonstrates many benefits, including no need for a second (donor) surgical site, rare risk of inferior alveolar nerve injury, and less pain and swelling, and others. Lateral bone augmentation through the ridge-split works best in a localized lateral bony defect intended for 1 or 2 implants and where the ridge is vertically intact. In this article, the authors present a detailed description of the implant-driven technique of alveolar ridge-split procedure in small and large bone deficiencies, in maxilla and mandible, supplemented by multiple photographs. The authors emphasize the need for careful manipulation of the thin ridge based on knowledge of precise surgical principles and stress that a practitioner needs specialized training and experience to perform this type of alveolar bone augmentation.

    Twenty-three patients had a painful ilioinguinal and/or iliohypogastric nerve entrapment syndrome following common surgical procedures in the lower portion of the abdomen (appendectomy, repair of inguinal hernia, and gynecologic procedures through transverse incision). The diagnostic triad of nerve entrapment after operation comprises (1) typical burning or lancinating pain near the incision that radiates to the area supplied by the nerve, (2) clear evidence of impaired sensory perception of the nerve, and (3) pain relieved by infiltration with anesthetic for local effects at the site where the two nerves leave the internal oblique muscle. Surgical repair of the scar with resection of the compromised nerve is the most effective treatment. Sixteen patients became symptom free after neurectomy, seven still suffer chronic pain in the scar. PMID:7065874

    It is well established that emotions are organized around two motivational systems: the defensive and the appetitive. Individual differences are relevant factors in emotional reactions, making them more flexible and less stereotyped. There is evidence that health professionals have lower emotional reactivity when viewing scenes of situations involving pain. The objective of this study was to investigate whether the rating of pictures of surgical procedure depends on their personal/occupational relevance. Fifty-two female Nursing (health discipline) and forty-eight Social Work (social science discipline) students participated in the experiment, which consisted of the presentation of 105 images of different categories (e.g., neutral, food), including 25 images of surgical procedure. Volunteers judged each picture according to its valence (pleasantness) and arousal using the Self-Assessment Manikin scale (dimensional approach). Additionally, the participants chose the word that best described what they felt while viewing each image (discrete emotion perspective). The average valence score for surgical procedure pictures for the Nursing group (M = 4.57; SD = 1.02) was higher than the score for the Social Work group (M = 3.31; SD = 1.05), indicating that Nursing students classified those images as less unpleasant than the Social Work students did. Additionally, the majority of Nursing students (65.4%) chose "neutral" as the word that best described what they felt while viewing the pictures. In the Social Work group, disgust (54.2%) was the emotion that was most frequently chosen. The evaluation of emotional stimuli differed according to the groups' personal/occupational relevance: Nursing students judged pictures of surgical procedure as less unpleasant than the Social Work students did, possibly reflecting an emotional regulation skill or some type of habituation that is critically relevant to their future professional work.

    This is a compact visual description of a combination of surgical technique and device for the delivery of (gene and cell) therapies into the spinal cord. While the technique is demonstrated in the animal, the procedure is FDA-approved and currently being used for stem cell transplantation into the spinal cords of patients with ALS. While the FDA has recognized proof-of-principle data on therapeutic efficacy in highly characterized rodent models, the use of large animals is considered critical for validating the combination of a surgical procedure, a device, and the safety of a final therapy for human use. The size, anatomy, and general vulnerability of the spine and spinal cord of the swine are recognized to better model the human. Moreover, the surgical process of exposing and manipulating the spinal cord as well as closing the wound in the pig is virtually indistinguishable from the human. We believe that the healthy pig model represents a critical first step in the study of procedural safety. PMID:23242422

    An evaluation of the surgical treatment for stress and mixed urinary incontinence and pelvic relaxation. One-year follow-up, was done. A retrospective study with 144 files from the surgeries performed between February 1993 and June 1994, at the Clínica de Urología Ginecológica del Instituto Nacional de Perinatología. We excluded 37 files because of incomplete information. The age, parity, hormonal stage, preoperative diagnosis by urodynamic studies, surgical treatments and one-year follow-up were analyzed. The mean age was 45.5 years. Pereyra procedure was performed in 53, Burch procedure in 47, anterior colporrhaphy in 5, and sling procedure in 2 patients. The incidence of complications was similar between the different groups. Resumption of spontaneous postsurgical voiding was delayed in the Pereyra group. The Burch urethropexy and Pereyra procedures were equally effective, with no statistical differences observed. Burch vaginal suspension was not more effective for the correction of urinary stress incontinence than Pereyra procedure. PMID:8754724

    Introduction Huge and multiple mesenteric fibroids (4,500 Kg weight) are very unusual. In many cases they are mistaken for subserosal fibroids of the womb due to the proximity with uterine walls. When they have a rapid growth, the risk of becoming malignant (sarcoma) has not to be underestimated. Surgery is challenging to remove abdominal nodes. Case report A case of a 40-year old woman, admitted to the hospital with abdominal masses occupying the entire cavity was reported. Both computerized tomography (CT) and ultrasounds (US) were not diriment for belonging of tumours. Clinical history of patient reports a laparoscopic removal of uterine fibroids, using the morcellator. Laparoscopy was performed four years before. Open surgery by means of a large transversal suprapubic laparotomy according to Pfannestiel was carried out. Multiple and huge mesenteric, peritoneal and intestinal tumours spread in the whole abdominal cavity were found, removed and examined by frozen section histology; in addition a series of small conglomerated myomas in the site of previous laparoscopic transumbilical route was taken away as well (the largest fibroid weighed Kg 3.500 and the all tumors removed 4,500 Kg); the result was benign (fibroids) and genital apparatus was preserved. Operation was challenging. Postoperative course was uneventful; after five days patient was discharged. Conclusions This case is very interesting for many factors: A) many extra-uterine fibroids spread throughout abdominal cavity; B) considerable weight of the masses C) intraoperative and postoperative danger. Finally, due to involvement of previous laparoscopic transumbilical incision together with other findings, the hypothesis of post laparoscopic dissemination has to be considered. A case of so large extragenital abdominal fibroids following laparoscopic uterine myomectomy has never been published so far. PMID:25827668

    Surgical simulation increasingly appears to be an essential aspect of tomorrow's surgery. The development of a hepatic surgery simulator is an advanced concept calling for a new writing system which will transform the medical world: virtual reality. Virtual reality extends the perception of our five senses by representing more than the real state of things by the means of computer sciences and robotics. It consists of three concepts: immersion, navigation and interaction. Three reasons have led us to develop this simulator: the first is to provide the surgeon with a comprehensive visualisation of the organ. The second reason is to allow for planning and surgical simulation that could be compared with the detailed flight-plan for a commercial jet pilot. The third lies in the fact that virtual reality is an integrated part of the concept of computer assisted surgical procedure. The project consists of a sophisticated simulator which has to include five requirements: visual fidelity, interactivity, physical properties, physiological properties, sensory input and output. In this report we will describe how to get a realistic 3D model of the liver from bi-dimensional 2D medical images for anatomical and surgical training. The introduction of a tumor and the consequent planning and virtual resection is also described, as are force feedback and real-time interaction. PMID:9554121

    Objective: We review our results after surgical reconstruction with the Nesbit’s procedure for congenital or acquired penile deviation. Patients and methods: Etiology of penile deviation, surgical outcome for straightening the penis, postoperative patient satisfaction and clinical findings were evaluated for 5 patients undergoing Nesbit’s procedure followed by a Medline review of contemporary literature regarding alternative surgical techniques. Follow-up included clinical examination, self-photography on erection and a standardized interview with erectile dysfunction assessment using IIEF-5 questionnaire. Results: Overall patient satisfaction was 100% in two patients, 2 patients were partly satisfied and 1 patient reported no satisfaction because of severe penile shortening with insufficiency for sexual intercourse postoperatively. Preoperative mean angulation of the penis was 42°. Four patients had Peyronie’s disease and 1 patient’s curvature resulted from an untreated penile fracture during sexual intercourse. Conclusion: The Nesbit technique can give satisfactory results for mild and moderate penile curvature. However, each technique for the reconstruction of penile deviation has its own advantages and disadvantages. Therefore proper patient selection has a major impact on further outcome. PMID:26504690

    AIM: To analyze the clinical features, diagnostic modalities, and the surgical management of urethral complications after tension-free vaginal tape procedures. METHODS: This study encompasses a retrospective review of nine patients presented with urethral complications after midurethral sling procedures. The patients underwent the procedures during a period from 1999 to 2012 in three different regional hospitals in the southwest part of Sweden. The time from sling placement to diagnosis, the risk factors, clinical features, diagnosis, surgical management, and functional outcome are presented. The presenting symptoms were described as either early onset (< 12 mo) or late onset (> 12 mo) according to when they were first reported. RESULTS: Eight cases of urethral erosion and one case of bladder-neck erosion were detected. The mean interval for diagnoses of the erosions ranged from 3 mo to 11 years. The most common presenting symptoms included de novo urgency with or without incontinence (7/9 patients), urinary retention/voiding dysfunction (4/9 patients), urethritis (4/9 patients), relapse of stress-incontinence (3/9 patients), recurrent urinary tract infections (5/9 patients), and hematuria (1/9 patient). In most cases, voiding dysfunction and urethritis occurred early after the operation. The surgical management applied in most cases was transurethral resection of the intraurethral part of the mesh. The removal of the intraurethral mesh resulted in improvement or complete cure of urgency symptoms in 5/7 patients with urgency. Four patients were reoperated with a new stress-incontinence surgery, one with laparoscopic Burch, and three with retropubic tension-free vaginal tape procedures. CONCLUSION: Urethral complications should be suspected in the case of de novo urgency and relapse of stress-incontinence. Transurethral excision of the intraurethral mesh is the recommended treatment. PMID:26167464

    Background A high perioperative inspiratory oxygen fraction may reduce the risk of surgical site infections, as bacterial eradication by neutrophils depends on wound oxygen tension. Two trials have shown that a high perioperative inspiratory oxygen fraction (FiO2 = 0.80) significantly reduced risk of surgical site infections after elective colorectal surgery, but a third trial was stopped early because the frequency of surgical site infections was more than doubled in the group receiving FiO2 = 0.80. It has not been settled if a high inspiratory oxygen fraction increases the risk of pulmonary complications, such as atelectasis, pneumonia and respiratory failure. The aim of our trial is to assess the potential benefits and harms of a high perioperative oxygen fraction in patients undergoing abdominal surgery. Methods and design The PROXI-Trial is a randomized, patient- and assessor blinded trial of perioperative supplemental oxygen in 1400 patients undergoing acute or elective laparotomy in 14 Danish hospitals. Patients are randomized to receive either 80% oxygen (FiO2 = 0.80) or 30% oxygen (FiO2 = 0.30) during surgery and for the first 2 postoperative hours. The primary outcome is surgical site infection within 14 days. The secondary outcomes are: atelectasis, pneumonia, respiratory failure, re-operation, mortality, duration of postoperative hospitalization, and admission to intensive care unit. The sample size allows detection of a 33% relative risk reduction in the primary outcome with 80% power. Discussion This trial assesses benefits and harms of a high inspiratory oxygen fraction, and the trial may be generalizable to a general surgical population undergoing laparotomy.

    2016-01-01

    The need for advanced hemostatic agents increases with the complexity of surgical procedures and use of anticoagulation and antiplatelet treatments. HEMOPATCH (Sealing Hemostat) is a novel, advanced hemostatic pad that is composed of a synthetic, protein-reactive monomer and a collagen backing. The active side is covered with a protein-reactive monomer: N-hydroxysuccinimide functionalized polyethylene glycol (NHS-PEG). NHS-PEG rapidly affixes the collagen pad to tissue to promote and maintain hemostasis. The combined action of the NHS-PEG and collagen is demonstrated to have benefit relative to other hemostatic agents in surgery and preclinical surgical models. This paper reviews the published investigations and case reports of the hemostatic efficacy of HEMOPATCH, wherein HEMOPATCH is demonstrated to be an effective, easy-to-use hemostatic agent in open and minimally invasive surgery of patients with thrombin- or platelet-induced coagulopathies.

    Objective: The purpose of this study was to evaluate compliance with guidelines in surgical prophylaxis (SP) procedures in Turkey. Materials and Methods: A point prevalence study involving 4 university, 5 education and research and 7 public hospitals was performed assessing compliance with guidelines for antibiotic use in SP. Compliance was based on the “Clinical Practice Guidelines for Antimicrobial Surgery (CPGAS) 2013” guideline. Results: Sixteen centers were included in the study, with 166 operations performed at these being evaluated. Parenteral antibiotic for SP was applied in 161 (96.9%) of these. Type of antibiotic was inappropriate in 66 (40.9%) cases and duration of use in 47 (29.1%). The main antibiotics used inappropriately in SP were ceftriaxone, glycopeptides and aminoglycosides. No significant difference was observed between secondary and tertiary hospitals in terms of inappropriate selection. Duration of prophylaxis was also incompatible with guideline recommendations in approximately half of surgical procedures performed in both secondary and tertiary hospitals, however statistical significance was observed between institutions in favor of tertiary hospitals. Conclusion: Antibiotics are to a considerable extent used in a manner incompatible with guidelines even in tertiary hospitals in Turkey. It must not be forgotten that several pre-, intra- and postoperative factors can be involved in the development of surgical site infections (SSI), and antibiotics are not the only option available for preventing these. A significant improvement can be achieved in prophylaxis with close observation, educational activities, collaboration with the surgical team and increasing compliance with guidelines. All health institutions must establish and apply their own SP consensus accompanied by the guidelines in order to achieve success in SP. PMID:27026760

    Patients who have cerebrovascular disease and vascular insufficiency routinely have neurosurgical and nonneurosurgical procedures. Anesthetic priorities must provide a still bloodless operative field while maintaining cardiovascular stability and renal function. Patients who have symptoms or a history of cerebrovascular disease are at increased risk for stroke, cerebral hypoperfusion, and cerebral anoxia. Type of surgery and cardiovascular status are key concerns when considering neuroprotective strategies. Optimization of current condition is important for a good outcome; risks must be weighed against perceived benefits in protecting neurons. Anesthetic use and physiologic manipulations can reduce neurologic injury and assure safe and effective surgical care when cerebral hypoperfusion is a real and significant risk. PMID:16935193

    Objective: This paper describes a text processing system designed to automate the manual data abstraction process in a quality improvement (QI) program. The Surgical Care and Outcomes Assessment Program (SCOAP) is a clinician-led, statewide performance benchmarking QI platform for surgical and interventional procedures. The data elements abstracted as part of this program cover a wide range of clinical information from patient medical history to details of surgical interventions. Methods: Statistical and rule-based extractors were developed to automatically abstract data elements. A preprocessing pipeline was created to chunk free-text notes into its sections, sentences, and tokens. The information extracted in this preprocessing step was used by the statistical and rule-based extractors as features. Findings: Performance results for 25 extractors (14 statistical, 11 rule based) are presented. The average f1-scores for 11 rule-based extractors and 14 statistical extractors are 0.785 (min=0.576,max=0.931,std-dev=0.113) and 0.812 (min=0.571,max=0.993,std-dev=0.135) respectively. Discussion: Our error analysis revealed that most extraction errors were due either to data imbalance in the data set or the way the gold standard had been created. Conclusion: As future work, more experiments will be conducted with a more comprehensive data set from multiple institutions contributing to the QI project. PMID:25848598

    Aim: Ankyloglossia, commonly known as tongue-tie, is a congenital oral anomaly characterized by a short lingual frenulum that may contribute to feeding, speech and mechanical problems. The purpose of this study is to compare the advantages of laser vis-à-vis conventional frenectomy in both intra- and post-surgical phases. Methods: This study took into consideration two patients, who were respectively 9 and 10-year-old. The first one underwent a common surgical procedure. A Nd:Yap laser device with a micropulsed wavelength of 1340 nm and power of 8 watts was used for the second. The postsurgical discomfort and healing characteristics were evaluated. Results: The results indicated that the Nd:Yap laser has the following advantages when compared to the conventional frenectomy: 1) soft tissue cutting was efficient, with no bleeding, giving a clear operative field; 2) there was no need to use sutures; 3) the surgery was less time-consuming; 4) there was no postsurgical infection and no need for analgesics or antibiotics; 5) wound contraction and scarring were decreased or eliminated; 6) despite the initial slowness of the healing process, the complete and final recovery was faster. Conclusion: Considering the above elements, it is possible to assert that the laser frenectomy has a series of unquestionable advantages if compared to the conventional surgical technique.

    Introduction Diverticulitis is a common diagnosis in the emergency department (ED). Outpatient management of diverticulitis is safe in selected patients, yet the rates of admission and surgical procedures following ED visits for diverticulitis are unknown, as are the predictive patient characteristics. Our goal is to describe trends in admission and surgical procedures following ED visits for diverticulitis, and to determine which patient characteristics predict admission. Methods : We performed a cross-sectional descriptive analysis using data on ED visits from 2006–2011 to determine change in admission and surgical patterns over time. The Nationwide Emergency Department Sample database, a nationally representative administrative claims dataset, was used to analyze ED visits for diverticulitis. We included patients with a principal diagnosis of diverticulitis (ICD-9 codes 562.11, 562.13). We analyzed the rate of admission and surgery in all admitted patients and in low-risk patients, defined as age <50 with no comorbidities (Elixhauser). We used hierarchical multivariate logistic regression to identify patient characteristics associated with admission for diverticulitis. Results Fryom 2006 to 2011 ED visits for diverticulitis increased by 21.3% from 238,248 to 302,612, while the admission rate decreased from 55.7% to 48.5% (−7.2%, 95% CI [−7.78 to −6.62]; p<0.001 for trend). The admission rate among low-risk patients decreased from 35.2% in 2006 to 26.8% in 2011 (−8.4%, 95% CI [−9.6 to −7.2]; p<0.001 for trend). Admission for diverticulitis was independently associated with male gender, comorbid illnesses, higher income and commercial health insurance. The surgical rate decreased from 6.5% in 2006 to 4.7% in 2011 (−1.8%, 95% CI [−2.1 to −1.5]; p<0.001 for trend), and among low-risk patients decreased from 4.0% to 2.2% (−1.8%, 95% CI [−4.5 to −1.7]; p<0.001 for trend). Conclusion From 2006 to 2011 ED visits for diverticulitis increased

    The consequences of controlled ventilation with positive end-expiratory pressure (PEEP) were studied, after cardiac surgical procedures, in two groups of patients supposed to have different lung and chest wall mechanical properties. The first group included 6 patients who had undergone coronary artery graft surgical procedures (CGS). The second group included 5 patients who had undergone a mitral valve replacement (MVR). Postoperatively, static lung and chest wall compliance was measured by stepwise inflation and deflation of the thorax. Esophageal, pericardial, and pleural pressures were then measured, and cardiac output was determined while PEEP was increased from 0 to 20 cm H2O. Lung and chest wall compliance values sharply decreased in MVR patients. This accounts for the lower values for pleural and pericardial pressures in this group than in the CGS patient group, but the transmission of airway pressure was identical in the two groups when PEEP was increased. The decrease in cardiac output induced by PEEP was similar in the two groups. The results suggest that the opposing influences of lung and chest wall compliance on airway pressure transmission could at least partly explain the hemodynamic effects of PEEP in patients in whom the mechanical properties of the lung and thorax are impaired. PEEP ventilation should be used cautiously in patients suspected of having thoracic rigidity. PMID:3532981

    The finding of intraperitoneal foreign body complicating surgical intervention broadly remains as an issue of safety in the operative room, a source of emotive concern for the patient, and an upsetting but equally embarrassing situation to the surgeon and the team. However, in the media world, it is a source of sumptuous and captivating headline on the newspaper and to the legal profession, an attractive case to prosecute. A middle age teacher presented with secondary infertility. She had emergency laparotomy fifteen years ago for ruptured tubal ectopic pregnancy in a private hospital and postoperative period was uneventful. Amongst other investigations to find out the cause of infertility, she had hysterosalpingography and a radio-opaque clamp was visualized on the films. She was counselled and had laparotomy. A pair of surgical Kocher clamps was retrieved buried in the mesentery. PMID:25436162

    Because surgical procedures require clinicians to develop and maintain procedural expertise and because blinding in randomized clinical trials of such therapies is often challenging, their critical appraisal raises unique issues. Risk of bias of trials of surgical procedures increases if investigators fail to rigorously conceal allocation and, where possible, to ensure blinding of those involved in the trial. Variability in surgeons' expertise can also increase bias and lead to important limitations in applicability. To address these issues, this Users' Guide to the Medical Literature reviews the use of remote randomization systems, blinding, sham-controlled trials, split-body trials, expertise-based trials, and mechanistic vs practical trials. Consideration of risk of bias and applicability issues will allow clinicians to make optimal use of trials addressing surgical procedures. PMID:27027568

    Objective. To evaluate the safety and efficacy of Keyless Abdominal Rope-Lifting Surgery (KARS), for tubal sterilization procedures in comparison with the conventional CO2 laparoscopy. Material and Methods. During a one-year period, 71 women underwent tubal ligation surgery. Conventional laparoscopy (N = 38) and KARS (N = 33) were used for tubal sterilization. In KARS, an abdominal access pathway through a single intra-abdominal incision was used to place transabdominal sutures that elevated the abdominal wall, and the operations were performed through the intraumbilical entry without the use of trocars. In CO2 laparoscopy, following the creation of the CO2 pneumoperitoneum a 10 mm trocar and two 5 mm trocars were introduced into the abdominal cavity. Tubal sterilizations were performed following the creation of the abdominal access pathways in both groups. The groups were compared with each other. Results. All operations could be performed by KARS without conversion to CO2 laparoscopy or laparotomy. The mean operative time of the two groups was not significantly different (P > 0.05). Intra- and postoperative findings including complications, bleeding, and hospital stay time did not differ between groups (P > 0.05). Conclusion. KARS for tubal sterilization seems safe and effective in terms of cosmesis, postoperative pain, and early hospital discharge. PMID:24453932

    Background Adjunctive hemostats are used to assist with the control of intraoperative bleeding. The most common types are flowables, gelatins, thrombins, and oxidized regenerated celluloses (ORCs). In the US, Surgicel® products are the only US Food and Drug Administration-approved ORCs. Objective To compare the outcomes of health care resource utilization (HRU) and costs associated with using ORCs compared to other adjunctive hemostats (OAHs are defined as flowables, gelatins, and topical thrombins) for surgical procedures in the US inpatient setting. Patients and methods A retrospective, US-based cohort study was conducted using hospital inpatient discharges from the 2011–2012 calendar years in the Premier Healthcare Database. Patients with either an ORC or an OAH who underwent a cardiovascular procedure (valve surgery and/or coronary artery bypass graft surgery), carotid endarterectomy, cholecystectomy, or hysterectomy were included. Propensity score matching was used to create comparable groups of ORC and OAH patients. Clinical, economic, and HRU outcomes were compared. Results The propensity score matching created balanced patient cohorts for cardiovascular procedure (22,718 patients), carotid endarterectomy (10,890 patients), cholecystectomy (6,090 patients), and hysterectomy (9,348 patients). In all procedures, hemostatic agent costs were 28%–56% lower for ORCs, and mean hemostat units per discharge were 16%–41% lower for ORCs compared to OAHs. Length of stay and total procedure costs for patients treated with ORCs were lower for carotid endarterectomy patients (0.3 days and US$700) and for cholecystectomy patients (1 day and US$3,350) (all P<0.001). Conclusion Costs and HRU for patients treated with ORCs were lower than or similar to patients treated with OAHs. Proper selection of the appropriate hemostatic agents has the potential to influence clinical outcomes and treatment costs. PMID:26604807

    With the developments in medical technology and increased surgical experience, advanced laparoscopic surgical procedures are performed successfully. Laparoscopic abdominal surgery is one of the best examples of advanced laparoscopic surgery (LS). Today, laparoscopic abdominal surgery in general surgery clinics is the basis of all abdominal surgical interventions. Laparoscopic abdominal surgery is associated with systemic and splanchnic hemodynamic alterations. Inadequate splanchnic perfusion in critically ill patients is associated with increased morbidity and mortality. The underlying pathophysiological mechanisms are still not well understood. With experience and with an increase in the number and diversity of the resulting data, the pathophysiology of laparoscopic abdominal surgery is now better understood. The normal physiology and pathophysiology of local and systemic effects of laparoscopic abdominal surgery is extremely important for safe and effective LS. Future research projects should focus on the interplay between the physiological regulatory mechanisms in the splanchnic circulation (SC), organs, and diseases. In this review, we discuss the effects of laparoscopic abdominal surgery on the SC. PMID:25561784

    Purpose: System-related complications in surgically implanted catheter-port systems (CPS) for intraarterial (i.a.) chemotherapy are well known. In most cases of complications, the treatment must be interrupted and the catheter-port system must be repaired surgically. We describe microinvasive interventional radiological procedures to correct some dysfunctions of CPS.Methods: Five patients with repetitive dysfunction of CPS were treated with interventional techniques. Two patients presented with perfusion impairment, one patient had a pseudoaneurysm of the hepatic artery, and two patients presented with catheter displacement. Radiological interventions included mechanical recanalization with a guidewire, vascular stenting, and correction of catheter dislocation with a goose-neck snare.Results: In all cases, correct function of the CPS was restored. No intervention-related complications occurred and surgery was avoided. Chemotherapy could be continued for a period of 4-10 months.Conclusion: For some system-related complications, minimally invasive radiological interventions can be used to restore the function of CPS for i.a. chemotherapy.

    Chordoma is known to be the most common primary tumor of the sacrum. Its surgery is challenging from many aspects. A large amount of bleeding is one of the biggest issues. A 52-year-old woman was admitted to our clinic with a huge mass at sacrum. The mass was diagnosed as chordoma after a needle biopsy. Prior to the surgery, a balloon dilation catheter (BDC) was placed in the distal abdominal aorta via the femoral artery. Just after the skin incision, the BDC was inflated with contrast medium and total occlusion of the aorta was achieved. At the end of the operation we observed that total hemorrhage had decreased dramatically. No complications were recorded except hypertension during the occlusion of the aorta which was expected. The patient was discharged after two weeks of hospitalization post-operatively without any neurological deficit. Our report is the second in the neurosurgical literature to our knowledge. Although this result is preliminary and needs to be replicated and expanded upon, our first experience with this method is effective for decreasing the amount of bleeding. We believe that our method prevents hemo-dynamical problems caused by massive bleeding and complications secondary to massive transfusion. PMID:19621292

    An original surgical method for gonadal protection in young women given pelvic radiation for Hodgkin's disease is presented. Lateral high ovarian transposition (LHAO) consists of the transposition of the ovaries into the paracolic gutter during staging laparotomy, after disconnecting the gonads from the fallopian tubes by dividing the tubo-ovarian vessels. The technique's effectiveness was assessed by a study using clinical investigation, radioimmunoassay (RIA) determination of sex hormones, and dosimetry; of 18 patients treated, 10 participated in the study. All but one have normal menses and hormone values, and one pregnancy occurred. We also calculated the doses absorbed by the ovaries and proved that, during inverted Y irradiation following LHAO, the ovaries are exposed to nearly one-half the dose they receive after traditional medial transposition. During subtotal nodal irradiation after LHAO, the irradiation dose is higher than after medialisation, but absolute values are minimal and castration is not induced.

    Background The National Healthcare Safety Network (NHSN) classifies surgical procedures into 40 categories. The objective of this study was to determine surgical site infection (SSI) incidence for clinically defined subgroups within 5 heterogeneous NHSN surgery categories. Methods This is a retrospective cohort study using the longitudinal State Inpatient Database. We identified 5 groups of surgical procedures (amputation; biliary, liver and pancreas [BILI]; breast; colon and hernia) using ICD-9-CM procedure codes in community hospitals in California, Florida and New York from January 2009 through September 2011 in persons aged ≥18 years. Each of these 5 categories was classified to more specific surgical procedures within the group. 90-day SSI rates were calculated using ICD-9-CM diagnosis codes. Results There were 62,901 amputation, 33,358 BILI, 72,058 breast, 125,689 colon and 85,745 hernia surgeries in 349,298 people. 90-day SSI rates varied significantly within each of the 5 subgroups. Within the BILI category, bile duct, pancreas and laparoscopic liver procedures had SSI rates of 7.2%, 17.2%, and 2.2%, respectively (p<0.0001 for each) compared to open liver procedures (11.1% SSI). Conclusion 90-day SSI rates varied widely within certain NHSN categories. Risk adjustment for specific surgery type is needed in order to make valid comparisons between hospitals. PMID:25818024

    Surgical navigation systems visualize the positions and orientations of surgical instruments and implants as graphical overlays onto a medical image of the operated anatomy on a computer monitor. The orthopaedic surgical navigation systems could be categorized according to the image modalities that are used for the visualization of surgical action. In the so-called CT-based systems or 'surgeon-defined anatomy' based systems, where a 3D volume or surface representation of the operated anatomy could be constructed from the preoperatively acquired tomographic data or through intraoperatively digitized anatomy landmarks, a photorealistic rendering of the surgical action has been identified to greatly improve usability of these navigation systems. However, this may not hold true when the virtual representation of surgical instruments and implants is superimposed onto 2D projection images in a fluoroscopy-based navigation system due to the so-called image occlusion problem. Image occlusion occurs when the field of view of the fluoroscopic image is occupied by the virtual representation of surgical implants or instruments. In these situations, the surgeon may miss part of the image details, even if transparency and/or wire-frame rendering is used. In this paper, we propose to use non-photorealistic rendering to overcome this difficulty. Laboratory testing results on foamed plastic bones during various computer-assisted fluoroscopybased surgical procedures including total hip arthroplasty and long bone fracture reduction and osteosynthesis are shown.

    A relatively new surgical technique allows for sutureless closure of a gastroschisis defect. Immediately after birth, a long umbilical cord stump is temporarily inverted into the abdominal cavity and later retracted and used to close the abdominal wall defect. Knowledge of this entity is important since the inverted umbilical cord simulates an intra-abdominal mass on cross-sectional imaging. While this procedure is well described in the surgical literature, the imaging features of inverted umbilical cord have yet to be reported. The case presented here highlights the sonographic imaging findings of the umbilical cord during the intestinal decompression phase of sutureless repair of gastroschisis. PMID:23907187

    The only method to slow or stop progressive damage caused by glaucoma, the leading cause of irreversible blindness, definitively shown to be effective, is lowering intraocular pressure, though there is also evidence that stabilizing the pressure may be beneficial. Performing surgery on the eye has proven effective in some cases, using various techniques, though with variable frequencies of success (stabilization of the disease) and various frequencies and severities of complications. Surgery offers the great advantage of longer duration of action than medicinal treatments presently available, and, also, of lessening the need of the patient to be faithful using suggested medications. There is a need to develop surgical procedures which will be effective in 1) lowering or stabilizing intraocular pressure in a way most likely to prevent glaucomatous deterioration, 2) causing the fewest and least severe problems, and 3) being the most economical. Recent efforts in this regard are promising, but not yet proven superior to well-performed trabeculectomy, itself an evolving procedure. PMID:26069522

    Background: Hemorrhages, cerebrospinal fluid (CSF) fistula and infections are the most challenging postoperative complications in Neurosurgery. In this study, we report our preliminary results using a fully autologous fibrin sealant agent, the Vivostat® system, in achieving hemostasis and CSF leakage repair during cranio-cerebral procedures. Methods: From January 2012 to March 2014, 77 patients were studied prospectively and data were collected and analyzed. Autologous fibrin sealant, taken from patient's blood, was prepared with the Vivostat® system and applied on the resection bed or above the dura mater to achieve hemostasis and dural sealing. The surgical technique, time to bleeding control and associated complications were recorded. Results: A total of 79 neurosurgical procedures have been performed on 77 patients. In the majority of cases (98%) the same autologous fibrin glue provided rapid hemostasis and dural sealing. No patient developed allergic reactions or systemic complications in association with its application. There were no cases of cerebral hematoma, swelling, infection, or epileptic seizures after surgery whether in the immediate or in late period follow-up. Conclusions: In this preliminary study, the easy and direct application of autologous fibrin sealant agent helped in controlling cerebral bleeding and in providing prompt and efficient dural sealing with resolution of CSF leaks. Although the use of autologous fibrin glue seems to be safe, easy, and effective, further investigations are strongly recommended to quantify real advantages and potential limitations. PMID:25984391

    Patients with severe panfacial injuries usually require long-term airway management. Nasal intubation may be contraindicated in case of nasoorbitoethmoidal fractures and also there may be a need for intraoperative and short-term postoperative intermaxillary fixation to achieve optimum reduction of fractures. The need for unobstructed access to the perinasal area during bimaxillary orthognathic procedures is felt many a time and to avoid a tracheostomy with its attending morbidity, many techniques have evolved that involve a submandibular/transmylohyoid or submental approach for temporary oroendotracheal intubation. In this article, we present our experience of patients by using submental/transmylohyoid route for endotracheal intubation. technique gives the surgeon and the anesthetist comfortable control over their respective domains, is easy to learn and implement in the operating protocol with no added costs.

    Open surgical repair (OSR) is a conventional surgical method used in the repair a ruptured abdominal aortic aneurysm (AAA); however, OSR results in high perioperative mortality rates. The level of serum angiotensin-converting enzyme 2 (ACE2) has been reported to be an independent risk factor for postoperative in-hospital mortality following major cardiopulmonary surgery. In the present study, the association of serum ACE2 levels with postoperative in-hospital mortality was investigated in patients undergoing OSR for ruptured AAA. The study enrolled 84 consecutive patients underwent OSR for ruptured AAA and were subsequently treated in the intensive care unit. Patients who succumbed postoperatively during hospitalization were defined as non-survivors. Serum ACE2 levels were measured in all patients prior to and following the surgery using ELISA kits. The results indicated that non-survivors showed significantly lower mean preoperative and postoperative serum ACE2 levels when compared with those in survivors. Multivariate logistic regression analysis also showed that, subsequent to adjusting for potential confounders, the serum ACE2 level on preoperative day 1 showed a significant negative association with the postoperative in-hospital mortality. This was confirmed by multivariate hazard ratio analysis, which showed that, subsequent to adjusting for the various potential confounders, the risk of postoperative in-hospital mortality remained significantly higher in the two lowest serum ACE2 level quartiles compared with that in the highest quartile on preoperative day 1. In conclusion, the present study provided the first evidence supporting that the serum ACE2 level is an independent risk factor for the in-hospital mortality following OSR for ruptured AAA. Furthermore, low serum ACE2 levels on preoperative day 1 were found to be associated with increased postoperative in-hospital mortality. Therefore, the serum ACE2 level on preoperative day 1 may be a potential

    option between conservative and operative management of small lumbar disc herniations or protrusions causing sciatica. Two RCT comparing transforaminal endoscopic procedures with microdiscectomy in patients with sciatica and small non-sequestered disc herniations show comparable short and medium term overall success rates. Concerning speed of recovery and return to work a trend towards more favourable results for the endoscopic procedures is noted. It is doubtful though, whether these results from the eleven and five years old studies are still valid for the more advanced procedures used today. The only RCT comparing the results of automated percutaneous lumbar discectomy to those of microdiscectomy showed clearly superior results of microdiscectomy. Furthermore, success rates of automated percutaneous lumbar discectomy reported in the RCT (29%) differ extremely from success rates reported in case series (between 56% and 92%). The literature search retrieves no controlled trials to assess efficacy and/or effectiveness of laser-discectomy, percutaneous manual discectomy or endoscopic procedures using a posterior approach in comparison to the standard procedures. Results from recent case series permit no assessment of efficacy, especially not in comparison to standard procedures. Due to highly selected patients, modi-fications of operative procedures, highly specialised surgical units and poorly standardised outcome assessment results of case series are highly variable, their generalisability is low. The results of the five economical analyses are, due to conceptual and methodological problems, of no value for decision-making in the context of the German health care system. Discussion Aside from low methodological study quality three conceptual problems complicate the interpretation of results. Continuous further development of technologies leads to a diversity of procedures in use which prohibits generalisation of study results. However, diversity is noted not only for

  4. The changing distribution of a major surgical procedure across hospitals: were supply shifts and disequilibrium important?

    This paper describes and analyzes the changing distribution across hospitals in the U.S. of total hip replacement surgery (THR) for the period 1980-1987. THR is one of the most costly single procedures contributing to health care expenses. Also, the use of THR exhibits a particularly high degree of geographic variation. Recent research pointed to shifts in demand as one plausible economic explanation for increasing use of THR. This paper questions whether shifts in supply may have been large enough to explain changes in patient mix and the relationship of patient mix to the number of procedures performed at a particular hospital. In addition, the relationship between total use of THR and the local availability of orthopaedic surgeons as well as the average allowable Medicare fee for standardized physician services is analyzed. These relationships might yield evidence to support a scenario of induced demand beyond the optimum for patients' welfare, or evidence of supply increase within a disequilibrium scenario. This study, using data for all THR patients in a large sample of hospitals, tends to reject the formulation of a market with independent supply and demand shifts where the supply shifts were the dominant forces. Hospitals with a larger number of THRs performed did not see a higher percentage of older, sicker, and lower income patients. It was more likely that demand shifts generated increases in capacity for surgical services. Moreover, there was little evidence for a persistent disequilibrium and only weak evidence for inducement. Also, we found little evidence that hospitals responded to financial incentives inherent in the Medicare payment system after 1983 to select among THR candidates in favour of those with below average expected cost. We did observe increased concentration over time of THR procedures in facilities with high volume--suggesting plausible demand shifts towards hospitals with a priori quality and cost advantages or who obtained those

    Purpose We assessed the applicability of a new multidirectional videoendoscope (digiCAMeleon, Karl Storz GmbH, Tuttlingen, Germany) in various neuroendoscopic procedures. Methods A 4-mm-diameter rigid videoendoscope (digiCAMeleon, Karl Storz GmbH, Tuttlingen, Germany) with 1 sensor and an internal LED light source was tested. The device offers a resolution of 1920 x 1080 pixels and weighs ≈ 215 g. The prototype was tested on three cadaveric heads using three different approaches: a) endoscopic endonasal transsphenoidal; b) frontal transcortical intraventricular; c) supraorbital. Results We identified several major benefits of the integrated system as applied to endoscopic endonasal, transcortical intraventricular, and endoscopic supraorbital keyhole approaches. These included improved maneuverability of the scope on account of reduced bulk and integration of the camera and fiberoptic light components, a variable angle of view from 0–70 degrees, and a novel feature that can be activated to maintain orientation of the surgical horizon. Our preliminary report highlights the potential for handling the videoendoscope in one hand, as one would a microsurgical instrument. The videoendoscope harbors all its electronic and lighting data into a unique and thin cable, thus resembling a modern "all-in-one" computer technology. Because of its reduced weight and ergonomic shape, controlling its movements is very easy and comfortable, even in the microsurgical environment. Furthermore, the videoendoscope offers the unique feature of orienting the horizon of vision, thanks to the possibility of offering angled views while working; this helps the surgeons to stay oriented with direct visualization and improved control of the instruments over a specific area of interest. Conclusions The videoendoscope prototype represents an HD-image quality versatile tool in a neurosurgical environment, thanks to its reduced weight and dimensions; in these preliminary simulations, we have

    OBJECTIVE The study purpose was to evaluate the associations between patient characteristics or surgical site classifications and the histologic remodeling scores of biologic meshes biopsied from abdominal soft tissue repair sites in the first attempt to generate a multivariable risk prediction model of non-constructive remodeling. INTRODUCTION Host characteristics and surgical site assessments may predict remodeling degree for biologic meshes used to reinforce abdominal tissue repair sites. METHODS Biologic meshes were biopsied from the abdominal tissue repair sites of n=40 patients during an abdominal re-exploration, stained with hematoxylin and eosin, and evaluated according to a semi-quantitative scoring system for remodeling characteristics [cell types (CT), cell infiltration (CI), extracellular matrix (ECM) deposition, scaffold degradation (SD), fibrous encapsulation (FE), and neovascularization (NEO)] and a mean composite score (CR). Biopsies were stained with Sirius Red & Fast Green, and analyzed to determine the collagen I:III ratio. Based on univariate analyses between subject clinical characteristics or surgical site classification and the histologic remodeling scores, cohort variables were selected for multivariable regression models using a p-value ≤0.200. RESULTS The model selection process for CI score yielded 2 variables: age at mesh implantation and mesh classification (c-statistic=0.989). For CR score, the model selection process yielded 2 variables: age at mesh implantation and mesh classification (r2=0.449). CONCLUSION These preliminary results constitute the first steps in generating a risk prediction model that predicts the patients and clinical circumstances most likely to experience non-constructive remodeling of abdominal tissue repair sites with biologic mesh reinforcement.

    Background The purpose of this study was to evaluate the associations between patient characteristics or surgical site classifications and the histologic remodeling scores of synthetic meshes biopsied from their abdominal wall repair sites in the first attempt to generate a multivariable risk prediction model of non-constructive remodeling. Methods Biopsies of the synthetic meshes were obtained from the abdominal wall repair sites of 51 patients during a subsequent abdominal re-exploration. Biopsies were stained with hematoxylin and eosin, and evaluated according to a semi-quantitative scoring system for remodeling characteristics (cell infiltration, cell types, extracellular matrix deposition, inflammation, fibrous encapsulation, and neovascularization) and a mean composite score (CR). Biopsies were also stained with Sirius Red and Fast Green, and analyzed to determine the collagen I:III ratio. Based on univariate analyses between subject clinical characteristics or surgical site classification and the histologic remodeling scores, cohort variables were selected for multivariable regression models using a threshold p value of ≤0.200. Results The model selection process for the extracellular matrix score yielded two variables: subject age at time of mesh implantation, and mesh classification (c-statistic = 0.842). For CR score, the model selection process yielded two variables: subject age at time of mesh implantation and mesh classification (r2 = 0.464). The model selection process for the collagen III area yielded a model with two variables: subject body mass index at time of mesh explantation and pack-year history (r2 = 0.244). Conclusion Host characteristics and surgical site assessments may predict degree of remodeling for synthetic meshes used to reinforce abdominal wall repair sites. These preliminary results constitute the first steps in generating a risk prediction model that predicts the patients and clinical circumstances for which non

    NASA Astrophysics Data System (ADS)

    Konh, Bardia

    Background: Majority of cancer interventions today are performed percutaneously using needle-based procedures, i.e. through the skin and soft tissue. Insufficient accuracy using conventional surgical needles motivated researchers to provide actuation forces to the needle's body for compensating the possible errors of surgeons/physicians. Therefore, active needles were proposed recently where actuation forces provided by shape memory alloys (SMAs) are utilized to assist the maneuverability and accuracy of surgical needles. This work also aims to introduce a novel needle insertion simulation to predict the deflection of a bevel tip needle inside the tissue. Methods: In this work first, the actuation capability of a single SMA wire was studied. The complex response of SMAs was investigated via a MATLAB implementation of the Brinson model and verified via experimental tests. The material characteristics of SMAs were simulated by defining multilinear elastic isothermal stress-strain curves. Rigorous experiments with SMA wires were performed to determine the material properties as well as to show the capability of the code to predict a stabilized SMA transformation behavior with sufficient accuracy. The isothermal stress-strain curves of SMAs were simulated and defined as a material model for the Finite Element Analysis of the active needle. In the second part of this work, a three-dimensional finite element (FE) model of the active steerable needle was developed to demonstrate the feasibility of using SMA wires as actuators to bend the surgical needle. In the FE model, birth and death method of defining boundary conditions, available in ANSYS, was used to achieve the pre-strain condition on SMA wire prior to actuation. This numerical model was validated with needle deflection experiments with developed prototypes of the active needle. The third part of this work describes the design optimization of the active using genetic algorithm aiming for its maximum flexibility

    Objective: Autologous chondrocyte implantation (ACI) involves the application of a chondrocyte suspension into a membrane-sealed cartilage defect. Recently, “cell-seeded collagen matrix-supported” ACI has been developed wherein chondrocytes are seeded on a biomembrane. This study aimed at preclinically comparing 4 variant ACI techniques in a refined goat model: 2 traditional procedures, whereby the defect is sealed by a periosteal flap or collagen membrane, and 2 cell-seeding methods, with the collagen membrane either sutured or glued into the defect. Design: The efficacy of the surgical techniques was evaluated in an acute critical size chondral defect in the medial condyle of 32 skeletally mature goats, randomly assigned to 1 of the 4 aforementioned treatment groups. After 10 weeks in vivo, the quality of the repair was graded histologically by 2 independent, blinded readers using the “modified O’Driscoll” score. Results: The cell-seeding procedure whereby the membrane is sutured into the defect has a similar structural repair capacity than traditional ACI techniques. However, when the cell-seeded membrane was glued into the defect, the outcome appeared inferior. Conclusion: These findings indicate that optimizing the goat model and the postoperative recovery does allow preclinical evaluation of ACI-based cartilage implants in a load-bearing setting. This preclinical observation provides support to the clinical utilization of the sutured membrane-seeded (ACI-CS) technique, provided sutures, but not fibrin sealants, are used to fix the cell-seeded membrane in the defect bed.

    Abstract The aim of the study is to evaluate the therapeutic effect of a new surgical procedure, dumbbell-form resection (DFR), for hilar cholangiocarcinoma (HCCA) with severe jaundice. In DFR, liver segments I, IVb, and partial V above the right hepatic pedicle are resected. Hemihepatectomy is recognized as the preferred procedure; however, its application is limited in HCCAs with severe jaundice. Thirty-eight HCCA patients with severe jaundice receiving DFR and 70 receiving hemihepatectomy from January 2008 to January 2013 were included. Perioperative parameters, operation-related morbidity and mortality, and post-operative survival were analyzed. A total of 21.1% patients (8/38) in the DFR group received percutaneous transhepatic biliary drainage (PTBD), which was significantly <81.4% (57/70) in the hemihepatectomy group. The TBIL was higher in the DFR group at operation (243.7 vs 125.6 μmol/L, respectively). The remnant liver volume was significantly higher after DFR. The operation-related morbidity was significantly lower after DFR than after hemihepatectomy (26.3% vs 48.6%, respectively). None of the patients died during the perioperative period after DFR, whereas 3 died after hemihepatectomy. There was no difference in margin status, histological grade, lymph-node involvement, and distant metastasis between the 2 groups. The 1-, 3-, and 5-year survival rates after DFR (68.4%, 32.1%, and 21.4%, respectively) showed no significant difference with those after hemihepatectomy (62.7%, 34.6%, and 23.3%, respectively). Kaplan–Meier analysis indicated that overall survival and recurrence after DFR demonstrated no significant difference compared with hemihepatectomy. DFR appears to be feasible for selected HCCA patients with severe jaundice. However, its indications should be restricted. PMID:26765439

    Otologic procedures require a still surgical field and are associated with a 50% incidence of emetic symptoms. Propofol reduces nausea and vomiting but not intraoperative movement. This study compares a remifentanil/propofol anesthetic to a propofol/fentanyl combination to determine which provides the best perioperative conditions for otologic microsurgery. Eighty healthy patients were randomly assigned to receive one of the anesthetic combinations. Demographic data, hemodynamic variables, movement, and bispectral index monitoring values in addition to anesthetic emergence, nausea, vomiting, pain, and other recovery variables were compared between groups with appropriate statistical methods. Both groups were similar. Times to eye opening (7.7 +/- 0.7 vs 12.4 +/- 1.2 minutes) and extubation (9.8 +/- 0.9 vs 12.4 +/- 1.0 minutes) were shorter with remifentanil. This group also had lower hemodynamic variables and movement (23% vs 65%) under anesthesia. Postoperative pain was mild in both groups, but remifentanil patients had more than the propofol group. All other postoperative parameters were similar. Remifentanil-based anesthesia produces better hemodynamic stability, less movement, and faster emergence after otologic surgery, with propofol's antiemetic effect, for the same cost. PMID:10652394

    Several surgical approaches are being used to induce myocardial ischemia in rats. The present study investigated two different operative procedures in spontaneously breathing and mechanically ventilated rats under sham conditions. A snare around the left coronary artery (LCA) was achieved without occlusion. Left lateral thoracotomy was performed in spontaneously breathing and mechanically ventilated rats (tidal volume 8 ml/kg) with a respiratory rate of 90 strokes/min at different levels of O2 supplementation (room air and 30, 40, and 90% O2). All animals were observed for 60 min after thoracotomy. Rats operated with exteriorization of the heart through left lateral thoracotomy while breathing spontaneously developed severe hypoxia and hypercapnia despite an intrathoracic operation time of <1 min. Arterial O2 content decreased from 18.7 +/- 0.5 to 3.3 +/- 0.9 vol%. Lactate increased from 1.2 +/- 0.1 to 5.2 +/- 0.3 mmol/l. Significant signs of ischemia were seen in the electrocardiogram up to 60 min. Mechanically ventilated animals exhibited a spectrum ranging from hypoxia (room air) to hyperoxia (90% O2). In order not to jeopardize findings in experimental myocardial ischemia-reperfusion injury models, stable physiological parameters can be achieved in mechanically ventilated rats at an O2 application of 30-40% at 90 strokes/min.

    The aim of this study was to assess the effect of emotional stress experienced by patients prior to surgery on the process of post-surgical recovery. The study covered 50 hospitalised patients (31 women and 19 men) who underwent hip replacement procedures. The research relied on STAI-X1 anxiety questionnaire, as well as a specially prepared survey and the analysis of medical documentation. The results of the study suggest that fears most frequently listed by patients include fear of pain and anaesthesia, as well as anxieties related to the possibility of medical complications and the need to rely on a stranger. A positive statistical correlation was found between the level of emotional stress and the occurrence of psychological and care problems in the first three days following the surgery (unfounded anxieties, self-removal of drainage, ports or dressing). In addition, a statistically significant relation was found between the emotional stress level before the surgery and the number of times the patient's blood pressure exceeded 140/90 mmHg (p = 0.0408), as well as his or her consumption of analgesics (p = 0.0033), sedatives (p = 0.0340) and soporific drugs (p = 0.0273) in postoperative period.

    Background: Elbow surgery is shared by several subspecialties. We were curious about the most common elbow surgeries and their corresponding diagnoses in the United States. Methods: We used the National Hospital Discharge Survey (NHDS) and the National Survey of Ambulatory Surgery (NSAS) data gathered in 2006-databases that together provide an estimate of all inpatient and ambulatory surgical care in the US. Results: An estimated 150,000 elbow surgeries were performed in the US in 2006, 75% in an outpatient setting. The most frequent diagnosis treated operative was enthesopathy (e.g. lateral epicondylitis) and it was treated with several different procedures. More than three quarters of all elbow surgeries treated enthesopathy, cubital tunnel syndrome, or fracture (radial head in particular). Arthroscopy and arthroplasty accounted for less than 10% of all elbow surgeries. Conclusions: Elbow surgery in the United States primarily addresses enthesopathies such as tennis elbow, cubital tunnel syndrome, and trauma. It is notable that some of the most common elbow surgeries (those that address enthesopathy and radial head fracture) are some of the most variably utilized and debated. PMID:25692163

    Objective Since European Society for Medical Oncology (ESMO) recommendations and French guidelines, pelvic lymphadenectomy should not be systematically performed for women with early-stage endometrioid endometrial cancer (EEC) preoperatively assessed at presumed low- or intermediate-risk. The aim of our study was to evaluate the change of our surgical practices after ESMO recommendations, and to evaluate the rate and morbidity of second surgical procedure in case of understaging after the first surgery. Methods This retrospective single-center study included women with EEC preoperatively assessed at presumed low- or intermediate-risk who had surgery between 2006 and 2013. Two periods were defined the times before and after ESMO recommendations. Demographics characteristics, surgical management, operative morbidity, and rate of understaging were compared. The rate of second surgical procedure required for lymph node resection during the second period and its morbidity were also studied. Results Sixty-one and sixty-two patients were operated for EEC preoperatively assessed at presumed low-or intermediate-risk before and after ESMO recommendations, respectively. Although immediate pelvic lymphadenectomy was performed more frequently during the first period than the second period (88.5% vs. 19.4%; p<0.001), the rate of postoperative risk-elevating or upstaging were comparable between the two periods (31.1% vs. 27.4%; p=0.71). Among the patients requiring second surgical procedure during the second period (21.0%), 30.8% did not undergo the second surgery due to their comorbidity or old age. For the patients who underwent second surgical procedure, mean operative time of the second procedure was 246.1±117.8 minutes. Third operation was required in 33.3% of them because of postoperative complications. Conclusion Since ESMO recommendations, second surgical procedure for lymph node resection is often required for women with EEC presumed at low- or intermediate-risk. This

  17. Abdominal aortic aneurysm.

    PubMed

    Keisler, Brian; Carter, Chuck

    2015-04-15

    Abdominal aortic aneurysm refers to abdominal aortic dilation of 3.0 cm or greater. The main risk factors are age older than 65 years, male sex, and smoking history. Other risk factors include a family history of abdominal aortic aneurysm, coronary artery disease, hypertension, peripheral artery disease, and previous myocardial infarction. Diagnosis may be made by physical examination, an incidental finding on imaging, or ultrasonography. The U.S. Preventive Services Task Force released updated recommendations for abdominal aortic aneurysm screening in 2014. Men 65 to 75 years of age with a history of smoking should undergo one-time screening with ultrasonography based on evidence that screening will improve abdominal aortic aneurysm-related mortality in this population. Men in this age group without a history of smoking may benefit if they have other risk factors (e.g., family history of abdominal aortic aneurysm, other vascular aneurysms, coronary artery disease). There is inconclusive evidence to recommend screening for abdominal aortic aneurysm in women 65 to 75 years of age with a smoking history. Women without a smoking history should not undergo screening because the harms likely outweigh the benefits. Persons who have a stable abdominal aortic aneurysm should undergo regular surveillance or operative intervention depending on aneurysm size. Surgical intervention by open or endovascular repair is the primary option and is typically reserved for aneurysms 5.5 cm in diameter or greater. There are limited options for medical treatment beyond risk factor modification. Ruptured abdominal aortic aneurysm is a medical emergency presenting with hypotension, shooting abdominal or back pain, and a pulsatile abdominal mass. It is associated with high prehospitalization mortality. Emergent surgical intervention is indicated for a rupture but has a high operative mortality rate. PMID:25884861

    Evaluating and "cleaning" of the uterine cavity is probably the most performed operation in women. It is done for several reasons: abortion, evaluation of irregular bleeding in premenopausal period, and postmenopausal bleeding. Abortion is undoubtedly the number one procedure with more than 44 million pregnancies terminated every year. This procedure should not be underestimated and a careful preoperative evaluation is needed. Ideally a sensitive pregnancy test should be done together with an ultrasound in order to confirm a uterine pregnancy, excluding extra-uterine pregnancy, and to detect genital and/or uterine malformations. Three out of four abortions are performed by surgical methods. Surgical methods include a sharp, blunt, and suction curettage. Suction curettage or vacuum aspiration is the preferred method. Despite the fact that it is a relative safe procedure with major complications in less than one percent of cases, it is still responsible for 13% of all maternal deaths. All the figures have not declined in the last decade. Trauma, perforation, and bleeding are a danger triage. When there is a perforation, a laparoscopy should be performed immediately, in order to detect intra-abdominal lacerations and bleeding. The bleeding should be stopped as soon as possible in order to not destabilize the patient. When there is a perforation in the uterus, this "entrance" can be used to perform the curettage. This is particularly useful if there is trauma of the isthmus and uterine wall, and it is difficult to identify the uterine canal. A curettage is a frequent performed procedure, which should not be underestimated. If there is a perforation in the uterus, then this opening can safely be used for vacuum aspiration. PMID:25134300

    Cadaveric surgical simulation carries the advantage of realistic anatomy and haptic feedback but has been historically difficult to model for intraventricular approaches given the need for active flow of CSF. This feasibility study was designed to simulate intraventricular neuroendoscopic approaches and techniques by reconstituting natural CSF flow in a cadaveric model. In 10 fresh human cadavers, a simple cervical laminectomy and dural opening were made, and a 12-gauge arterial catheter was introduced. Saline was continuously perfused at physiological CSF pressures to reconstitute the subarachnoid space and ventricles. A neuroendoscope was subsequently inserted via a standard right frontal bur hole. In 8 of the 10 cadavers, adequate reconstitution and endoscopic access of the lateral and third ventricles were achieved. In 2 cadavers, ventricular access was not feasible, perhaps because of a small ventricle size and/or deteriorated tissue quality. In all 8 cadavers with successful CSF flow reconstitution and endoscopic access, identifying the foramen of Monro was possible, as was performing septum pellucidotomy and endoscopic third ventriculostomy. Furthermore, navigation of the cerebral aqueduct, fourth ventricle, prepontine cistern, and suprasellar cistern via the lamina terminalis was possible, providing a complementary educational paradigm for resident education that cannot typically be performed in live surgery. Surgical simulation plays a critical and increasingly prominent role in surgical education, particularly for techniques with steep learning curves including intraventricular neuroendoscopic procedures. This novel model provides feasible and realistic surgical simulation of neuroendoscopic intraventricular procedures and approaches. PMID:25859805

  1. Smart surgical needle actuated by shape memory alloys for percutaneous procedures

    Konh, Bardia

    Background: Majority of cancer interventions today are performed percutaneously using needle-based procedures, i.e. through the skin and soft tissue. Insufficient accuracy using conventional surgical needles motivated researchers to provide actuation forces to the needle's body for compensating the possible errors of surgeons/physicians. Therefore, active needles were proposed recently where actuation forces provided by shape memory alloys (SMAs) are utilized to assist the maneuverability and accuracy of surgical needles. This work also aims to introduce a novel needle insertion simulation to predict the deflection of a bevel tip needle inside the tissue. Methods: In this work first, the actuation capability of a single SMA wire was studied. The complex response of SMAs was investigated via a MATLAB implementation of the Brinson model and verified via experimental tests. The material characteristics of SMAs were simulated by defining multilinear elastic isothermal stress-strain curves. Rigorous experiments with SMA wires were performed to determine the material properties as well as to show the capability of the code to predict a stabilized SMA transformation behavior with sufficient accuracy. The isothermal stress-strain curves of SMAs were simulated and defined as a material model for the Finite Element Analysis of the active needle. In the second part of this work, a three-dimensional finite element (FE) model of the active steerable needle was developed to demonstrate the feasibility of using SMA wires as actuators to bend the surgical needle. In the FE model, birth and death method of defining boundary conditions, available in ANSYS, was used to achieve the pre-strain condition on SMA wire prior to actuation. This numerical model was validated with needle deflection experiments with developed prototypes of the active needle. The third part of this work describes the design optimization of the active using genetic algorithm aiming for its maximum flexibility

    INTRODUCTION Expenditures on material supplies and medications constitute the greatest per capita costs for surgical missions. We hypothesized that supply acquisition at nonprofit organization (NPO) costs would lead to significant cost-savings compared to supply acquisition at US academic institution costs from the provider perspective for hernia repairs and minor procedures during a surgical mission in the Dominican Republic (DR). METHODS Items acquired for a surgical mission were uniquely QR-coded for accurate consumption accounting. Both NPO and US academic institution unit costs were associated with each item in an electronic inventory system. Medication doses were recorded and QR-codes for consumed items were scanned into a record for each sampled procedure. Mean material costs and cost savings ± SDs were calculated in US dollars for each procedure type. Cost-minimization analyses between the NPO and the US academic institution platforms for each procedure type ensued using a two-tailed Wilcoxon matched-pairs test with α=0.05. Item utilization analyses generated lists of most frequently used materials by procedure type. RESULTS The mean cost savings of supply acquisition at NPO costs for each procedure type were as follows: $482.86 ± $683.79 for unilateral inguinal hernia repair (IHR, n=13); $332.46 ± $184.09 for bilateral inguinal hernia repair (BIHR, n=3); $127.26 ± $13.18 for hydrocelectomy (HC, n=9); $232.92 ± $56.49 for femoral hernia repair (FHR, n=3); $120.90 ± $30.51 for umbilical hernia repair (UHR, n=8); $36.59 ± $17.76 for minor procedures (MP, n=26); and $120.66 ± $14.61 for pediatric inguinal hernia repair (PIHR, n=7). CONCLUSION Supply acquisition at NPO costs leads to significant cost-savings compared to supply acquisition at US academic institution costs from the provider perspective for IHR, HC, UHR, MP, and PIHR during a surgical mission to DR. Item utilization analysis can generate minimum-necessary material lists for each procedure

    Background: High-risk organizations such as aviation rely on simulations for the training and assessment of technical and team performance. The aim of this study was to develop a simulated environment for surgical trainees using similar principles. Methods: A total of 27 surgical trainees carried out a simulated procedure in a Simulated Operating Theatre with a standardized OR team. Observation of OR events was carried out by an unobtrusive data collection system: clinical data recorder. Assessment of performance consisted of blinded rating of technical skills, a checklist of technical events, an assessment of communication, and a global rating of team skills by a human factors expert and trained surgical research fellows. The participants underwent a debriefing session, and the face validity of the simulated environment was evaluated. Results: While technical skills rating discriminated between surgeons according to experience (P = 0.002), there were no differences in terms of the checklist and team skills (P = 0.70). While all trainees were observed to gown/glove and handle sharps correctly, low scores were observed for some key features of communication with other team members. Low scores were obtained by the entire cohort for vigilance. Interobserver reliability was 0.90 and 0.89 for technical and team skills ratings. Conclusions: The simulated operating theatre could serve as an environment for the development of surgical competence among surgical trainees. Objective, structured, and multimodal assessment of performance during simulated procedures could serve as a basis for focused feedback during training of technical and team skills. PMID:16244534

    Debate over the role of Becker expander implants (BEIs) in breast reconstruction is still ongoing. There are no clear indications for BEI use. The main indications for BEI use are one-stage breast reconstruction procedure and congenital breast deformities correction, due to the postoperative ability to vary BEI volume. Recent studies showed that BEIs were removed 5 years after mammary reconstruction in 68% of operated patients. This entails a further surgical procedure. BEIs should not, therefore, be regarded as one-stage prostheses. We performed a case-series study of breast reconstructions with anatomically shaped Becker-35™ implants, in order to highlight complications and to flag unseen problems, which might entail a second surgical procedure. A total of 229 patients, reconstructed from 2005 to 2010, were enrolled in this study. Data relating to implant type, volume, mean operative time and complications were recorded. All the patients underwent the same surgical procedure. The minimum follow-up period was 18 months. During a 5-year follow-up, 99 patients required secondary surgery to correct their complications or sequelae; 46 of them underwent BEI removal within 2 years of implantation, 56 within 3 years, 65 within 4 years and 74 within 5 years. Our findings show that two different sorts of complications can arise with these devices, leading to premature implant removal, one common to any breast implant and one peculiar to BEIs. The Becker implant is a permanent expander. Surgeons must, therefore, be aware that, once positioned, the Becker expander cannot be adjusted at a later date, as in two-stage expander/prosthesis reconstructions for instance. Surgeons must have a clear understanding of possible BEI complications in order to be able to discuss these with their patients. Therefore, only surgeons experienced in breast reconstruction should use BEIs. PMID:23478009

  9. Does an expanding fetal abdominal mass produce pulmonary hypoplasia?

    1987-06-01

    Fetal pulmonary hypoplasia has been related to multiple factors. In an effort to define which fetuses may benefit from prenatal intervention to prevent or reverse pulmonary hypoplasia, we studied the relative contribution of an enlarging abdominal mass in the fetus. We produced abdominal masses in fetal rabbits at 24 days gestation by two methods. In one group, a small cylindrical chip of Takasen, (a synthetic polymer that expands to 50 times its size in 1 week; Grobeast, Pop Art Co, Cleveland, OH) was inserted into the peritoneal cavity of the fetal rabbit; in another group, the bladder neck was obstructed with a surgical clip. Amniotic fluid volume was restored at the surgical procedure. Sham-operated littermates served as controls. At cesarean delivery on day 30, fetal lung, liver, and body weights were measured, and the abdominal masses were quantitated by volume displacement of the removed mass or bladder. In both groups large abdominal masses of comparable size were produced. Newborns with the synthetic abdominal mass did not have significant pulmonary hypoplasia, but often had a prune belly deformity of the abdominal wall, whereas newborns with bladder obstruction had significant pulmonary hypoplasia. Liver weight was not significantly affected. We conclude that a fetal abdominal mass does not independently produce pulmonary hypoplasia, possibly because the "mass effect" is relieved by distension of the abdominal wall rather than elevation of the diaphragm; the pulmonary hypoplasia that occurs in bladder outlet obstruction is probably due to the associated oligohydramnios rather than the mass effect of the dilated urinary tract; and prenatal decompression of an abdominal mass or dilated urinary tract is not justified to prevent pulmonary hypoplasia in the absence of oligohydramnios.

    This retrospective study evaluated the precision and positional accuracy of different orthognathic procedures following virtual surgical planning in 30 patients. To date, no studies of three-dimensional virtual surgical planning have evaluated the influence of segmentation on positional accuracy and transverse expansion. Furthermore, only a few have evaluated the precision and accuracy of genioplasty in placement of the chin segment. The virtual surgical plan was compared with the postsurgical outcome by using three linear and three rotational measurements. The influence of maxillary segmentation was analyzed in both superior and inferior maxillary repositioning. In addition, transverse surgical expansion was compared with the postsurgical expansion obtained. An overall, high degree of linear accuracy between planned and postsurgical outcomes was found, but with a large standard deviation. Rotational difference showed an increase in pitch, mainly affecting the maxilla. Segmentation had no significant influence on maxillary placement. However, a posterior movement was observed in inferior maxillary repositioning. A lack of transverse expansion was observed in the segmented maxilla independent of the degree of expansion.

    Surgical simulation increasingly appears to be an essential aspect of tomorrow's surgery. The development of a hepatic surgery simulator is an advanced concept calling for a new writing system which will transform the medical world: virtual reality. Virtual reality extends the perception of our five senses by representing more than the real state of things by the means of computer sciences and robotics. It consists of three concepts: immersion, navigation and interaction. Three reasons have led us to develop this simulator: the first is to provide the surgeon with a comprehensive visualisation of the organ. The second reasons is to allow for planning and surgical simulation that could be compared with the detailed flight-plan for a commercial jet pilot. The third lies in the fact that virtual reality is an integrated part of the concept of computer assisted surgical procedure. The project consists of a sophisticated simulator which must include five requirements: a) visual fidelity, b) interactivity, c) physical properties, d) physiological properties, e) sensory input and output. In this report we describe how to obtain a realistic 3D model of the liver from bi-dimensional 2D medical images for anatomical and surgical training. The introduction of a tumor and the consequent planning and virtual resection is also described, as are force feedback and real-time interaction. PMID:9752550

    We know that experienced endoscopic surgeons, despite having extensive training, may make a rare but fatal mistake. Prof. Takeshi Ohdaira developed a device visualizing brain action potential to reflect the latent psychological instability of the surgeon. The Ohdaira system consists of three components: a real-time brain action potential measurement unit, a simulated abdominal cavity, and an intra-abdominal monitor. We conducted two psychological stress tests by using an artificial laparoscopic simulator and an animal model. There were five male subjects aged between 41 to 61 years. The psychological instability scores were considered to reflect, to some extent, the number of years of experience of the surgeon in medical care. However, very high inter-individual variability was noted. Furthermore, we discovered the following: 1) bleeding during simulated laparoscopic surgery--an episode generally considered to be psychological stress for the surgeon--did not form the greatest psychological stress; 2) the greatest psychological stress was elicited at the moment when the surgeon became faced with a setting in which his anatomical knowledge was lacking or a setting in which he presumed imminent bleeding; and 3) the excessively activated action potential of the brain possibly leads to a procedural error during surgery. A modified brain action potential measurement unit can reveal the latent psychological instability of surgeons that possibly leads to errors in surgical procedures. PMID:26054987

    Neoadjuvant chemotherapy has more and more become clinical routine during the past years. Results from large randomized trials like NSABP-B18 show that survival parameters are not affected if sequence of therapy is changed. Survival parameters have been intensively studied, but surgical standards after primary chemotherapy are much less well defined. Results from the early trials comparing lumpectomy or quadrantectomy with mastectomy are generally transposed to the neoadjuvant situation. In this context the "result of downstaging" is surgically treated like otherwise the primary tumor would have been treated. Though local recurrence rates reported after primary chemotherapy are not increased within the whole population this may not be correct for subgroups. E.g. within the NSABP-B18 trial significantly higher local recurrence rates are reported for those patients who initially were proposed to have mastectomy and who actually received lumpectomy after effective primary chemotherapy. Another unresolved problem is surgery after complete remission, which as histopathology demonstrates corresponds often not to pathological complete remission. Therefore in most cases the initially involved area is resected, which may result in a more radical surgical approach to complete remission than to partial remission. Further standardisation of surgical approach to patients after neoadjuvant chemotherapy should be evaluated within phase III trials. PMID:10857211

    Making an effort to control health expenditure's escalation, especially in hospital, the Belgian government is planning and experimenting with prospective budgeting. A research financed by the Ministry of Public Health allows us to point out the structure of the pathologies treated as well as other variables included in the medical MBDS like urgency, number of diseased systems, ... and explains a high percentage of the variance (62%) in drugs expenditures of the surgical cases. These variables have to be used in order to calibrate hospital drugs budgets. The Interdisciplinary Centre in Health Economics has developed tools to compare drugs prescriptions by type of surgical procedures in order to help hospitals to evaluate their performance should such drugs budgets be progressively introduced.

    Surgical treatment of an infected abdominal aortic aneurysm (IAAA) is difficult and the ideal graft material is a subject of debate. A 60-year-old man with untreated diabetes mellitus was referred to our hospital presenting with fever and left lower abdominal pain. The patient was diagnosed with an IAAA by blood culture and computed tomography. We treated the patient surgically for the IAAA using bilateral reversed superficial femoral veins which were shaped into a bifurcated graft. No signs of recurrent infection or aneurysmal dilation were observed for 3 years after the procedure. PMID:27087879

    We reviewed the English-language clinical literature on carotid endarterectomy, cholecystectomy, upper gastrointestinal endoscopy, colonoscopy, coronary angiography and coronary artery bypass graft procedure to identify the appropriateness of using these procedures in 1981. Most of the 803 relevant articles and textbooks were published after 1975; about 10% of the 571 research studies were randomized, controlled trials, while two thirds were retrospective studies. Incomplete or contradictory information was available on the indications for and efficacy of using the procedures; almost no data were available on costs and use; data on complications failed to specify patients' symptoms or the relationship between complications and reasons for doing the procedure.

    Several modern learning frameworks (eg, cognitive apprenticeship, anchored instruction, and situated cognition) posit the utility of nontraditional methods for effective experiential learning. Thus, development of novel educational tools emphasizing the cognitive framework of operative sequences may be of benefit to surgical trainees. We propose the development and global deployment of an effective, mobile cognitive cardiac surgical simulator. In methods, 16 preclinical medical students were assessed. Overall, 4 separate surgical modules (sternotomy, cannulation, decannulation, and sternal closure) were created utilizing the Touch Surgery (London, UK) platform. Modules were made available to download free of charge for use on mobile devices. Usage data were collected over a 6-month period. Educational efficacy of the modules was evaluated by randomizing a cohort of medical students to either module usage or traditional, reading-based self-study, followed by a multiple-choice learning assessment tool. In results, downloads of the simulator achieved global penetrance, with highest usage in the USA, Brazil, Italy, UK, and India. Overall, 5368 unique users conducted a total of 1971 hours of simulation. Evaluation of the medical student cohort revealed significantly higher assessment scores in those randomized to module use versus traditional reading (75% ± 9% vs 61% ± 7%, respectively; P < 0.05). In conclusion, this study represents the first effort to create a mobile, interactive cognitive simulator for cardiac surgery. Simulators of this type may be effective for the training and assessment of surgical students. We investigated whether an interactive, mobile-computing-based cognitive task simulator for cardiac surgery could be developed, deployed, and validated. Our findings suggest that such simulators may be a useful learning tool. PMID:27568126

    We describe an impressive and rare case of surgical emphysema after minimally invasive rectal surgery. This case reports on a patient who developed massive retroperitoneal, intraperitoneal and subcutaneous emphysema directly following a transanal endoscopic microsurgery (TEM) procedure for a rectal intramucosal carcinoma. Free intra-abdominal air after gastro-intestinal surgery can be a sign of a bowel perforation or anastomotic leakage. This is a serious complication often requiring immediate surgery. In our patient an abdominal computed tomography-scan with rectal contrast showed no signs of a rectal perforation. Therefore this emphysema was caused by the insufflation of CO2 gas in the rectum during the TEM-procedure. Conservative treatment resulted in an uneventful recovery. With the increasing usage of TEM for rectal lesions we expect this complication to occur more often. After ruling out a full thickness rectal wall perforation in patients with surgical emphysema following TEM, conservative treatment is the treatment of choice. PMID:25161765

    The Ross procedure is an excellent choice for younger patients in need of aortic valve replacement. While patients have benefited from superior survival rates associated with this procedure, complications related to aortic root dilatation and degeneration of the autograft may be encountered later in life. These challenges may be exacerbated in those with underlying connective tissue abnormalities, a phenomenon commonly observed in the bicuspid aortic valve population. In this report, we present the case of a patient who presented with an aortic dissection 16 years after a Ross procedure for aortic insufficiency in the setting of a bicuspid aortic valve, and review the existing literature related to this adverse event.

    Odontogenic myxoma (OM) is an uncommon benign tumor with aggressive and invasive behavior. Predominant symptoms are usually slow and painless swelling, sometimes resulting in perforation of the cortical borders of the affected bone. In this paper, a case report of a patient with an OM on the right maxillary sinus and a vertical excess of maxilla will be presented. The treatment chosen was tumor resection in association with orthognathic surgery with biomodels assessment for surgical planning. A 3-year follow-up showed disease free and stability of the new position of maxilla. The international literature is evaluated to discuss this case report. PMID:24124313

    Tracheogastric tube fistulas are rare but fatal complications after esophagectomy. Anesthetic management for a patient with this complication is challenging because air leakage and mechanical ventilation may cause aspiration. We present a case report of the anesthetic management of a patient having 2-stage surgical repair combined with endoscopic mucosal resection for a giant carinal tracheogastric tube fistula. The first stage was separation of the gastric tube above the fistula with spontaneous breathing under local anesthesia and sedation. The second stage was complete separation and reconstruction of the digestive tract under epidural and general anesthesia with spontaneous breathing and pressure support before insertion of a decompression tube.

    Numerous methods of surgical repair for scaphocephaly (sagittal synostosis) have been reported in the literature, from strip craniectomies to more complex methods of calvarial vault remodeling. While good cosmesis and restoration of a normal anteroposterior diameter may be obtained with these methods, a more rounded contour of the biparietal areas is often more difficult to achieve. We describe a modification of the Pi technique, described by Jane in 1976, that results in a more rounded contour of the biparietal areas. We report our experience on cranial vault remodeling for the correction of scaphocephaly in 51 patients from 1998 to 2011. PMID:23154346

    We used a high-speed 3-dimensional (3D) image analysis system (SYNAPSE VINCENT, Fujifilm Corp, Tokyo, Japan) to determine the best positioning of robotic arms and instruments preoperatively. The da Vinci S (Intuitive Surgical Inc, Sunnyvale, CA) was easily set up accurately and rapidly for this operation. Preoperative simulation and intraoperative navigation using the SYNAPSE VINCENT for robot-assisted thoracic operations enabled efficient planning of the operation settings. The SYNAPSE VINCENT can detect the tumor location and depict surrounding tissues quickly, accurately, and safely. This system is also excellent for navigational and educational use. PMID:24882302

    The management of patients with penetrating abdominal trauma is outlined in Figure 1. Patients with hemodynamic instability, evisceration, significant gastrointestinal bleeding, peritoneal signs, gunshot wounds with peritoneal violation, and type 2 and 3 shotgun wounds should undergo emergency laparotomy. The initial ED management of these patients includes airway management, monitoring of cardiac rhythm and vital signs, history, physical examination, and placement of intravenous lines. Blood should be obtained for initial hematocrit, type and cross-matching, electrolytes, and an alcohol level or drug screen as needed. Initial resuscitation should utilize crystalloid fluid replacement. If more than 2 liters of crystalloid are needed to stabilize an adult (less in a child), blood should be given. Group O Rh-negative packed red blood cells should be immediately available for a patient in impending arrest or massive hemorrhage. Type-specific blood should be available within 15 minutes. A patient with penetrating thoracic and high abdominal trauma should receive a portable chest x-ray, and a hemo- or pneumothorax should be treated with tube thoracostomy. An unstable patient with clinical signs consistent with a pneumothorax, however, should receive a tube thoracostomy prior to obtaining roentgenographic confirmation. If time permits, a nasogastric tube and Foley catheter should be placed, and the urine evaluated for blood (these procedures can be performed in the operating room). If kidney involvement is suspected because of hematuria or penetrating trauma in the area of a kidney or ureter in a patient requiring surgery, a single-shot IVP should be performed either in the ED or the operating room. An ECG is important in patients with possible cardiac involvement and in patients over the age of 40 going to the operating room. Tetanus status should be updated, and appropriate antibiotics covering bowel flora should be given. Operative management should rarely be delayed

    Both horizontal recti are transpositioned in unilateral elevator deficiency, leaving no alternative to correct any significant ipsilateral horizontal deviation. An effective method to correct vertical and horizontal deviations simultaneously is reported. A modified Knapp's procedure was performed by transposition of the superior half of equally divided (up to 15 mm) medial and lateral recti for vertical deviation and the inferior half after suitable recession or resection for horizontal deviation. This procedure was performed in ten patients who had type II unilateral elevator deficiency with horizontal deviation ranging from 18 to 45 prism diopters (PD). We were able to correct 20 PD of horizontal deviation and 25 PD of vertical deviation with a modified Knapp's procedure without any significant adverse effects after a follow-up of 21 months. A modified Knapp's procedure is recommended for unilateral elevator deficiency associated with horizontal deviation. PMID:12757102

    In this Statistical Grand Rounds, we review methods for the analysis of the diversity of procedures among hospitals, the activities among anesthesia providers, etc. We apply multiple methods and consider their relative reliability and usefulness for perioperative applications, including calculations of SEs. We also review methods for comparing the similarity of procedures among hospitals, activities among anesthesia providers, etc. We again apply multiple methods and consider their relative reliability and usefulness for perioperative applications. The applications include strategic analyses (e.g., hospital marketing) and human resource analytics (e.g., comparisons among providers). Measures of diversity of procedures and activities (e.g., Herfindahl and Gini-Simpson index) are used for quantification of each facility (hospital) or anesthesia provider, one at a time. Diversity can be thought of as a summary measure. Thus, if the diversity of procedures for 48 hospitals is studied, the diversity (and its SE) is being calculated for each hospital. Likewise, the effective numbers of common procedures at each hospital can be calculated (e.g., by using the exponential of the Shannon index). Measures of similarity are pairwise assessments. Thus, if quantifying the similarity of procedures among cases with a break or handoff versus cases without a break or handoff, a similarity index represents a correlation coefficient. There are several different measures of similarity, and we compare their features and applicability for perioperative data. We rely extensively on sensitivity analyses to interpret observed values of the similarity index. PMID:26678472

    The purpose of this study was to reveal the occurrence of nail-patella syndrome (NPS) in Saudi Arabia together with the detection of abnormal attachment of lateral meniscus in the left knee and new surgical procedures applied to the right and left knee, reported for the first time in this study. This was a case study of a 23-year-old young man presenting with bilateral knee pain, giving way and locking since the age of 15 years. Clinically, most of the NPS features were noted, including ocular problems. The complex features affected both knees, especially the previous attempted surgeries for recurrent dislocation of patellae. Deficient ligaments were reconstructed using the Leeds-Keio ligament, starting with the right knee and continuing with the left knee 6 months later. Early and late follow-up showed favorable outcome of surgery revealed as independent ambulation and stable right and left knees. In conclusion, NPS, although rare, presents a complex problem and unexpected surgical outcome, and we recommend this procedure with close follow-up. PMID:15266233

  12. Surgical sterilization: an underutilized procedure for evaluating the merits of induced sterility

    1993-01-01

    Despite more than 4 decades of effort, development of effective wildlife damage control programs based on sterilization of target species has met with limited success. This is partly due to the fact that investigators have assumed, rather than empirically tested, whether the reproductive strategies of the target populations were vulnerable to the planned treatment. Equally important, methods selected to include sterility usually involve a chemical agent that can affect sociosexual behaviors of the nuisance population. In this report, we illustrate how surgically induced sterility circumvents both problems--how the concept without the potentially confounding secondary effects of a chemical. We assessed the merits of initiating research to develop a male chemosterilant for Norway rats, red-winged blackbirds, beaver, and Canada geese by inducing sterility surgically. The infidelity of many red-winged females to their polygynous territorial male was surprising and argued against searching for a male sterilant. On the other hand, beaver and Canada goose studies confirmed previous reports that both form par-bonds and are monogamous. Both should be vulnerable to a male chemosterilant approach, and research toward this goal is justified.

    Nausea and vomiting following anesthesia is a distressing problem for the patient as it increases the recovery time, intensity of nursing care and delays discharge. The aim of randomized controlled single blind study is to evaluate the efficacy and safety of subhypnotic doses of propofol for the prevention of postoperative nausea and vomiting (PONV) in day care management of cases in oral and maxillofacial surgeries. Twenty-five patient of ASA-1 with age ranging from 12 to 40 years were scheduled for various maxillofacial surgical cases like fracture, cyst enucleation, surgical removal of 3rd molar, etc. were given propofol at the dose of 2 to 2.5 mg/kg as induction dose and sedation was maintained with the dose 5 to 10 mg/min. There was no significant effect on heart rate, systolic and diastolic blood pressure, respiratory rate and oxygen saturation intraoperatively. In conclusion, a subhypnotic dose of propofol is fast acting, safe and easily controllable, short acting general anesthetic agent with rapid recovery. The study found that the PONV was significantly reduced in the patient with propofol, no hemodynamic derangements were noted in the postoperative period. PMID:24309336

    Prosthetic rehabilitation of patients with oral submucous fibrosis (OSMF) offers a formidable challenge due to restricted mouth opening. Physiotherapy via interocclusal force application is the mainstay for surgical treatment. Herein, we report a case of a man with OSMF requiring construction of dentures. The main objective was to deliver intra-operative and post operative inter occlusal forces without fracturing the mandible and thus providing rehabilitation to the patient prosthetically. An edentulous male patient reported with grade IVA OSMF to our department to improve his mouth opening for denture construction. The patient was managed successfully using surgical sectioning of the fibrous bands. Inter occlusal force application for mouth opening during the operation and post operative physiotherapy were facilitated using custom-made occlusal splints. Satisfactory mouth opening was achieved, with good healing and no event of infection or fracture. Here, we propose an easy method to achieve adequate mouth opening in an edentulous patient of OSMF, with atrophic ridges; without the chances of fracture of either jaw. PMID:22442590

    When should a patient with abdominal pain be referred to the emergency ward? The following goals must be achieved upon managing patients with acute abdominal pain: 1) identify vital emergency situations; 2) detect surgical conditions that require emergency referral without further diagnostic procedures; 3) in "non surgical acute abdomen patients" perform appropriate diagnostic procedures, or in selected cases delay tests and reevaluate the patient after an observation period, after which a referral decision is made. Clues from the history and physical examination are critical to perform this evaluation. A good knowledge of the most frequent acute abdominal conditions, and identifying potential severity criteria allow an appropriate management and decision about emergency referral. PMID:20873434

    Double aortic aneurysm (DAA) falls under the category of multiple aortic aneurysms. Repair is generally done through staged surgery due to low invasiveness. In this approach, one aneurysm is cured per operation. Therefore, two operations are required for DAA. However, post-first-surgery rupture cases have been reported. Although the problems involved with managing staged surgery have been discussed for more than 30 years, investigation from a hemodynamic perspective has not been attempted. Hence, this is the first computational fluid dynamics approach to the DAA problem. Three idealized geometries were prepared: presurgery, thoracic aortic aneurysm (TAA) cured, and abdominal aortic aneurysm (AAA) cured. By applying identical boundary conditions for flow rate and pressure, the Navier-Stokes equation and continuity equations were solved under the Newtonian fluid assumption. Average pressure in TAA was increased by AAA repair. On the other hand, average pressure in AAA was decreased after TAA repair. Average wall shear stress was decreased at the peak in post-first-surgery models. However, the wave profile of TAA average wall shear stress was changed in the late systole phase after AAA repair. Since the average wall shear stress in the post-first-surgery models decreased and pressure at TAA after AAA repair increased, the TAA might be treated first to prevent rupture. PMID:24348172

    Introduction: Laparoscopic gastric plication (LGCP) reduces gastric volume without resecting or implanting a foreign body. Although still considered investigational, it could be appropriate for young patients with a low body mass index (BMI) and for those unwilling to undergo sleeve gastrectomy, gastric banding, or bypass. Objectives: The aim of this study was to assess the mid-term results (2 years) of LGCP in terms of safety and efficacy. Methods: A total of 56 obese patients (47 female; mean age=30.5±11.7 years; mean BMI=40.31±4.7 kg/m2) were candidates for LGCP from January 2011 to October 2013. Early and late complications, BMI, and excess BMI loss (EBL) were prospectively recorded at 3, 6, 9, 12, 18, and 24 months follow-up. Results: Mean operative time was 72.4±15.6 minutes. No conversion was required. Mean hospital stay was 3 days. Mean %EBL was 34.3±18.40%, 40.1±24.5%, 47.4±30.2%, 46.5±34.6%, 47.8±43.2%, and 55.3±53.6% at 3, 6, 9, 12, 18, and 24 months, respectively. The overall complication rate was 32.14%. Perioperative mortality was zero. Surgical revision was needed in 30 patients: 12 for unsatisfactory weight loss and 18 for gastric prolapse (one acute within 30 days), respectively. Conclusion: LGCP showed high complication rates requiring surgical revision. PMID:26421246

    We developed and evaluated a surgical procedure for implanting intra-abdominal radiotransmitters with external whip antennas in captive mallards (Anas platyrhynchos). Transmitters were implanted in the abdominal cavity and the antennas exited through the caudal abdominal wall and skin. Birds with implanted transmitters developed mild to moderate localized air sac reactions. These reactions involved adhesions of the right anterior abdominal air sac to the liver with contractions around the transmitters and antenna catheters. The adhesions were reinforced by a proliferation of connective tissue and lined by multinucleated giant cells (foreign body reaction). Casual observation indicated that neither behavior nor activity of the birds was altered by the histological reaction to the transmitter implant. No increase in systemic lesions (particularly liver or kidney) could be correlated with the histological reactions. Our evaluations indicate that the procedure is a reliable method for radiomarking ducks and the technique has been successfully used in 2 field studies.

    Asian Indians exhibit unique features of obesity; excess body fat, abdominal adiposity, increased subcutaneous and intra-abdominal fat, and deposition of fat in ectopic sites (liver, muscle, etc.). Obesity is a major driver for the widely prevalent metabolic syndrome and type 2 diabetes mellitus (T2DM) in Asian Indians in India and those residing in other countries. Based on percentage body fat and morbidity data, limits of normal BMI are narrower and lower in Asian Indians than in white Caucasians. In this consensus statement, we present revised guidelines for diagnosis of obesity, abdominal obesity, the metabolic syndrome, physical activity, and drug therapy and bariatric surgery for obesity in Asian Indians after consultations with experts from various regions of India belonging to the following medical disciplines; internal medicine, metabolic diseases, endocrinology, nutrition, cardiology, exercise physiology, sports medicine and bariatric surgery, and representing reputed medical institutions, hospitals, government funded research institutions, and policy making bodies. It is estimated that by application of these guidelines, additional 10-15% of Indian population would be labeled as overweight/obese and would require appropriate management. Application of these guidelines on countrywide basis is also likely to have a deceleration effect on the escalating problem of T2DM and cardiovascular disease. These guidelines could be revised in future as appropriate, after another large and countrywide consensus process. Till that time, these should be used by clinicians, researchers and policymakers dealing with obesity and related diseases. PMID:19582986

    Aim To assess the efficacy of the procedural consolidation concept (PCC) at reducing the number of sessions of general anesthesia necessary for treating children with epidermolysis bullosa (EB). Methods We examined the records of children treated at Children's Hospital of Zagreb between April 1999 and December 2007. Children treated before the introduction of PCC in January 2005 (n = 39) and after (n = 48) were analyzed in order to determine the effect of PCC on the occurrence of complications, days of hospitalization, and number of hospitalizations. Results During the study period, 53 patients underwent 220 sessions of general anesthesia for a total of 743 surgical interventions per session. Before the introduction of PCC (n = 39 patients, 83 sessions), the median number of interventions per session was 2 (range 1-5), and after the introduction of PCC (n = 48 patients, 137 sessions) it was 4 (range 3-7, P < 0.001). After the introduction of PCC, the median number of complications per anesthesia session increased from 2 (range 0-10) to 3 (range 0-10) (P = 0.027), but the median number of complications per surgical procedure decreased from 1 (range 0-10) to 0.6 (range 0-2.5) (P < 0.001). PCC lengthened each anesthesia session from a median of 65 minutes (range 35-655) to 95 minutes (range 50-405), (P < 0.001). Total length of hospitalization was similar before (median 1, range 1-4) and after (median 1, range 1-3) introduction of PCC (P = 0.169). The number of hospitalization days per procedure was 3 times lower after the introduction of PCC (median 0.3, range 0.2-3) than before (median 1, range 0.75-1.7) (P < 0.001). Conclusion PCC should be considered an option in the surgical treatment of children with EB. PMID:21853547

    Actinomycosis is a chronic suppurative infection, for which immune suppression is a predisposing factor. In unusual cases, this disease may present as an abdominal wall involvement simulating a soft tissue tumor as seen in the present case. The presented patient had no signs of trauma or surgical approach and the pathology was considered to be a primary abdominal wall actinomycosis. Preoperative diagnosis is difficult due to the nonspecific nature of clinical presentation, radiographic and laboratory findings. Surgery combined with antibiotic treatment is a curative approach for this relatively rare infection. Surgeons must be aware of this disease in order to ensure correct diagnosis and to prevent performing any unnecessary procedures. The present study describes a case of abdominal actinomycosis with multiple myeloma, together with a review of important points related to this disease. PMID:25202429

    We describe a case of painful snapping in the medial aspect of the knee of a 40-year-old man, following a knee hyperflexion injury. Dynamic real-time ultrasonography determined that the snapping was due to the distal tendon of sartorius passing over a medial meniscal cyst. The patient subsequently underwent arthroscopic decompression of the cyst instead of an inappropriate hamstring tendon harvest procedure, with complete resolution of symptoms. PMID:24198995

    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

    The Fontan surgery for single ventricle heart defects is a typical example of a clinical intervention in which patient-specific computational modeling can improve patient outcome: with the functional heterogeneity of the presenting patients, which precludes generic solutions, and the clear influence of the surgically-created Fontan connection on hemodynamics, it is acknowledged that individualized computational optimization of the post-operative hemodynamics can be of clinical value. A large body of literature has thus emerged seeking to provide clinically relevant answers and innovative solutions, with an increasing emphasis on patient-specific approaches. In this review we discuss the benefits and challenges of patient-specific simulations for the Fontan surgery, reviewing state of the art solutions and avenues for future development. We first discuss the clinical impact of patient-specific simulations, notably how they have contributed to our understanding of the link between Fontan hemodynamics and patient outcome. This is followed by a survey of methodologies for capturing patient-specific hemodynamics, with an emphasis on the challenges of defining patient-specific boundary conditions and their extension for prediction of post-operative outcome. We conclude with insights into potential future directions, noting that one of the most pressing issues might be the validation of the predictive capabilities of the developed framework.

    Objective To examine the content and quality of written information provided by surgical centres for patients undergoing oesophagectomy for cancer. Design Cross-sectional study of the content of National Health Service (NHS) patient information leaflets (PILs) about oesophageal cancer surgery, using a modified framework approach. Data sources Written information leaflets from 41 of 43 cancer centres undertaking surgery for oesophageal cancer in England and Wales (response rate 95.3%). Eligibility criteria All English language versions of PILs about oesophagectomy. Results 32 different PILs were identified, of which 2 were generic tools (Macmillan ‘understanding cancer of the gullet’ and EIDO ‘oesophagectomy’). Although most PILs focused on describing in-hospital adverse events, information varied widely and was often misleading. Just 1 leaflet described survival benefits of surgery and 2 mentioned the possibility of disease recurrence. Conclusions Written information provided for patients by NHS cancer centres undertaking oesophagectomy is inconsistent and incomplete. It is recommended that surgeons work together with patients to agree on standards of information provision of relevance to all stakeholders’ needs. PMID:26459487

    Fifty five children with 57 cholesteatomas (2 bilateral cholesteatomas) were operated on by the same surgeon. The median period of follow-up was 87 months. Fifteen cases were lost to follow-up (26%). An ossicular erosion was present in 76% of cases. In the first stage, an "intact canal wall technique" (ICWT) was carried out in 44% and a "canal wall down technique" (CWDT) in 56%. A planned second stage was carried out in 76% of ICWT and 56% of CWDT. The incidence of residual cholesteatoma was 29% and the incidence of recurrent cholesteatoma was 11%. A third stage was carried out in 6 cases (11%) without residual or recurrent cholesteatoma. Finally a CWDT was performed in 65% and a ICWT in 35%. The hearing results were significantly better with ICWT but this was due to a better preoperative hearing level. Whatever the surgical technique, the hearing results were better in the presence of an intact stapes. The surgery was individualized. Although ICWT is our priority technique, it was feasible, in our experience, only in a minority of cases because of difficult ablation, insufficient eustachian tube function and very advanced sigmoid sinus or very low lying tegmen plate. Minimal postoperative cavity problems were encountered, even in children where in our experience the mastoidal pneumatisation is limited. PMID:9827188

    Five patients who had undergone renal transplantation 3 months to 23 years ago were operated on successfully for an abdominal aortic aneurysm. In the first case, dating from 1973, the kidney was protected by general hypothermia. In the remaining patients, no measure was used to protect the kidney. Only one patient showed a moderate increase of blood creatinine in the postoperative period; renal function returned to normal in 15 days. All five patients have normal renal function 6 months to 11 years after aortic repair. Results obtained in this series show that protection of the transplant during aortic surgery is not necessary, provided adequate surgical technique is used. Such a technique is described in detail. Its use simplifies surgical treatment of such lesions and avoids the complex procedures employed in the seven previously published cases. Images FIGS. 1A and B. FIGS. 2A and B. FIGS. 3A and B.

    Because of the increased use of fluoroscopic guidance techniques in certain orthopaedic surgical procedures, surgeons and other operating-room personnel who are involved in these procedures are voicing growing concern over possible associated radiation health hazards. Using thin-layer lithium fluoride chips for thermoluminescence dosimetry, we directly measured the radiation exposure encountered by the primary surgeon during seven operative procedures that were done utilizing fluoroscopic guidance techniques. Dosimetry studies were also carried out using a tissue-equivalent phantom model to determine the directions of maximum scatter radiation. These studies indicated that the standard protective apron that is commonly worn during the use of fluoroscopy provides adequate protection to most of the body; however, the surgeon is exposed to significant levels of scatter radiation to the head, neck, and hands, Dosimetry studies showed that positioning the fluoroscopic beam vertically to the fracture site of the supine patient, with the x-ray source posterior to the patient, provided the lowest levels of scatter radiation to the surgeon in the normal working position.

    Flail chest is a life-threatening situation that paradoxical movement of the thoracic cage was caused by multiply fractured ribs in two different planes, or a sternal fracture, or a combination of the two. The methods to achieve stability of the chest wall are controversy between surgical fixation and mechanical ventilation. We report a case of a 33-year-old man who fell from a high place with fail chest due to multiple rib fractures bilaterally and horizontal sternal fracture. The conventional surgical stabilization using metal plates by access to the front of the sternum could not provide stability of the flail segment because the fracture surface was obliquely upward and there were multiple bilateral rib fractures adjacent the sternum. The Nuss procedure was performed for supporting the flail segment from the back. Flail chest was resolved immediately after the surgery. The patient was weaned from the mechanical ventilation on third postoperative day successfully and was ultimately discharged without any complications. PMID:27293864

    Desmopressin acetate (DA) is a synthetic analog of vasopressin that may improve perioperative coagulation in cardiac surgical patients. Twenty-seven adult patients with good left ventricular function and normal preoperative coagulation profiles scheduled to undergo elective cardiac surgery participated in the double-blinded, placebo-controlled study. The 14 patients in the DA group received the drug over 10 minutes (starting 15 minutes after protamine administration). The 13 patients in the placebo group received an equal volume of saline. Preoperative template bleeding time was longer in the placebo group (P = 0.04). Otherwise, there were no statistically significant differences between the groups in demographics, coagulation variables, renal concentrating function, blood loss, or transfusion requirements at any study interval. The only significant hemodynamic differences detected were an increase in cardiac output in the DA group and a corresponding decrease in systemic vascular resistance. Five of 13 patients who received DA required treatment for hypotension, whereas none of 12 patients who received placebo required treatment during the infusion (P = 0.008). The authors conclude that DA causes mild vasodilation, but does not reduce blood loss or transfusion requirements in patients undergoing primary uncomplicated cardiac surgical procedures.

    Purpose: Polydactyly is a most common congenital hand defect in which the hand has one or more extra fingers, commonly seen post axial i.e. on the small finger side, affecting about one out of every 1,000 babies. It is usually treated by surgically removing the extra finger typically, when the child is between 1 and 2 years old. Prognosis after removal of extra digit is good, though not devoid of complications like scar formation, instability and late deformity which may need additional reconstructive surgery to recover full function and improve the hand's appearance. The evidence of polydactyly is linked with superstitions related with divine phenomenon. Due to the myth and fear of complications, parents hesitate or are reluctant to opt for surgery. Method: In this study, Ksharsutra, an Ayurvedic medicated thread coated with herbal alkaline drugs having simultaneous cutting and healing property was used by free ligation technique to remove extra finger in a child, whose parents were not willing to undergo surgery. This was an observational single case design without controlled group. Result: After Ksharsutra ligation, the extra finger started necrosing within 24 hours. The finger turned bluish to black in next 3 days with minimal pain at the site of ligation and finally sloughed out in just nine days with minimal scar formation. Conclusion: Ksahrsutra Ligation showed excellent result in postaxial polydactyly. The results are encouraging enough to warrant more studies to establish and promote this unique para surgical procedure i.e. Ksharsutra in the management of postaxial Polydactyly.

    OBJECTIVE- To describe the clinical characteristics, treatment, complications, and outcome of dogs and cats treated surgically for major abdominal evisceration. DESIGN- Retrospective case series. ANIMALS- 8 dogs and 4 cats. PROCEDURES- Medical records from January 1998 through March 2008 were reviewed to identify animals that underwent surgery for major abdominal evisceration. Data regarding cause of evisceration, signalment, physiologic variables, and hematologic variables were collected. Details of treatment, duration of hospitalization, and outcome were recorded. Linear regression analysis was performed to evaluate the association of signalment, physiologic variables, and hematologic variables on the number of days of hospitalization. RESULTS- Major abdominal evisceration was secondary to a traumatic event in 4 animals and to postsurgical dehiscence in 8 animals. All animals had evisceration of the intestines and gross contamination with dirt, leaves, or litter. Two animals eviscerated the spleen, and 1 animal had a perforated colon and was leaking feces into the peritoneal cavity. All animals underwent exploratory abdominal surgery. Surgical procedures performed included resection of compromised intestine, body wall repair, diaphragmatic hernia repair, nephrectomy, splenectomy, and primary colonic repair. All animals survived to discharge from the hospital. Median duration of hospitalization was 4 days (range, 1 to 7 days). Factors associated with an increase in duration of hospitalization included evisceration secondary to trauma, high lactate concentration at time of admission, and small body size. CONCLUSIONS AND CLINICAL RELEVANCE- Despite the dramatic appearance of major abdominal evisceration in cats and dogs, prompt and aggressive medical and surgical intervention can provide a favorable outcome.

    Incisional hernia is one of the classic complications after abdominal surgery. The chronic, gradual increase in size of some of these hernias is such that the hernia ring widens to a point where there is a loss of substance in the abdominal wall, herniated organs can become incarcerated or strangulated while poor abdominal motility can alter respiratory function. The surgical treatment of small (<5 cm) incisional hernias is safe and straightforward, by either laparotomy or laparoscopy. For large hernias, surgical repair is often difficult. After reintegration of herniated viscera into the abdominal cavity, the abdominal wall defect must be closed anatomically in order to restore the function to the abdominal wall. Prosthetic reinforcement of the abdominal wall is mandatory for long-term successful repair. There are multiple techniques for prosthetic hernia repair, but placement of Dacron mesh in the retromuscular plane is our preference. PMID:23137643

    Actinomycosis is a chronic suppurative granulomatous infectious disease caused by actinomyces species that is characterized by formation of characteristic clumps called as sulfur granules. Abdominal actinomycosis is a rare disease and is often difficult to diagnose before operation. Abdominal actinomycosis infiltrating into the abdominal wall and adhering to the colon is even rarer. Most abdominal actinomycosis develops after operation, trauma or inflammatory bowel disease, and is also considered as an opportunistic infection in immunocompromised patient with underlying malignancy, diabetes mellitus, human immunodeficiency virus infection, etc. Actinomycosis is diagnosed based on histologic demonstration of sulfur granules in surgically resected specimen or pus, and treatment consists of long-term penicillin based antibiotics therapy with or without surgical resection. Herein, we report an unusual case of abdominal wall actinomycosis which developed in a patient after acupuncture and presented as abdominal wall mass that was first mistaken for abdominal wall invasion of diverticulum perforation.

    The use of high-level magnification (6-8x loupes magnification, or higher degrees of magnification provided by the surgical operating microscope), combined with head-mounted, coaxial lighting, may improve the ability of a dentist or dental hygienist to perform prophylaxis or scaling and root planing procedures, compared to the performance of these tasks using unaided vision or entry-level (2.5x) magnification, combined with overhead operatory lighting. A magnified view of the supragingival contours of a tooth surface facilitates visualizing the dimensions and curvature of the unseen sub-gingival tooth surfaces, which facilitates detection and removal of calculus that is located on these subgingival surfaces. Improved calculus removal ability may lead to better periodontal disease outcomes. PMID:24245463

    Background To review the clinical experience and short- to middle-term effects of the Nuss procedure for correction of pectus excavatum (PE). Methods From September 2006 to August 2014, 639 patients with PE were treated using the Nuss procedure. Of these, 546 were male and 93 were female. The mean age was 15.3±5.8 years (2.5-49 years). Preoperative chest CT scans Haller index (HI) was 4.3±1.7 (2.9-17.4), with 75 cases of mild PE (HI <3.2), 114 cases of moderate PE (HI 3.2-3.5), 393 cases of severe PE (HI 3.6-6.0), and 57 cases of extremely severe PE (HI >6.0). Results A total of 638 patients successfully completed the surgery, an 11-year-old male patient who died after the surgery had undergone ventricular septal defect closure surgery through a sternal incision 7 years ago. The mean operative time was 64.3±41.7 min (40-310 min). Excluding the patient who died, the average blood loss was 24.5±17.8 mL (10-160 mL). The average length of postoperative hospital stay was 5.2±2.9 days (4-36 days). A total of 484 cases (75.7%) required 1 steel bar insertion, 153 cases (24.0%) required 2 steel bars, and 2 cases (0.3%) required 3 bars. Postoperative evaluation of the surgery outcomes revealed the following: excellent in 504 cases, good in 105, fair in 28 and poor in 2, good quality rate was 95.3%. Conclusions Correction of PE via the Nuss procedure is minimally invasive and simple to perform with good short and mid-term effects, while long-term efficacy remains to be determined. PMID:26543607

    Narrow-diameter implants (NDIs) are increasingly produced and used in implant dentistry, especially since the introduction of new, more resistant materials. The objective of the present study was to evaluate the clinical performance of NDIs (3.3 mm) placed in thin alveolar crests. Twenty consecutive patients needing implant-supported fixed partial dentures and presenting an alveolar thickness ≤6 mm were treated with 1 or several NDIs. The surgical protocol was chosen according to the clinical situation: (1) flapless, (2) mini-cervical flap, (3) wide flap, (4) wide flap + guided bone regeneration (GBR). Implants were immediately loaded if the primary stability was higher than 20 Ncm. Implant survival and success, prosthodontic success rates, and patient-centered outcomes were evaluated after a follow-up period of 1 year. A total of 39 implants were placed in 20 patients, 12 and 27 implants in the anterior regions and in the posterior mandible, respectively. All but 1 implant reached an insertion torque higher than 20 Ncm and were loaded within 48 hours. The implant survival and success rates both reached 94.7%. The need for GBR was avoided in 60% of the implant sites. The mean peri-implant bone remodeling after a follow-up period of 1 year was -0.35 mm at the implant level. Peri-implant bone remodeling was higher in the posterior region, when the alveolar crest was thinner than 4 mm and GBR was required in addition. In conclusion, use of NDIs to restore partial edentation in sites with limited horizontal thickness seems to be an effective treatment option that prevented GBR in the majority of the present cases. Immediate provisionalization of NDIs does not seem to impair the results. PMID:24766161

    Surgery for primary hyperparathyroidism (pHPT) has a high cure-rate and few complications. Preoperative localization procedures have permitted a dramatic shift from routine bilateral exploration to focused, minimally invasive procedures. At Odense University Hospital, Denmark, the introduction of focused surgery was combined with training of new surgeons. The objective of this study was to identify possible risk factors for treatment failure with special focus on surgical strategy and training of new surgeons. A 6-year prospective and consecutive series of 567 pHPT patients operated at Odense University hospital, Denmark, was analyzed. A shift in strategy was made in 2006 and at the same time new surgeons started training in parathyroid surgery. Biochemical-, clinical- and follow-up data were analyzed. Overall cure-rate was 90.7 %. Complication rates were 1.1 % for hemorrhage, 1.1 % for wound infection and 0.9 % for recurrent nerve paralysis. The only significant predictor of treatment failure at 6 months was histology of hyperplasia (OR 4.3). Neither the introduction of minimal invasive surgical strategy nor the training of new surgeons had a significant influence on the rate of treatment failures. Hyperplasia is a significant predictor of treatment failure in pHPT surgery. A shift towards systematic preoperative localization with focused surgery as well as training of new surgeons can be done without negative impact on treatment results. Identification of the hyperplasia and multigland patients in need of bilateral cervical exploration is crucial to avoid failures and raise cure rates. PMID:26044404

    Background The possibility of using stem cells for regenerative medicine has opened a new field of investigation. The search for sources to obtain multipotent stem cells from discarded tissues or through non-invasive procedures is of great interest. It has been shown that mesenchymal stem cells (MSCs) obtained from umbilical cords, dental pulp and adipose tissue, which are all biological discards, are able to differentiate into muscle, fat, bone and cartilage cell lineages. The aim of this study was to isolate, expand, characterize and assess the differentiation potential of MSCs from human fallopian tubes (hFTs). Methods Lineages of hFTs were expanded, had their karyotype analyzed, were characterized by flow cytometry and underwent in vitro adipogenic, chondrogenic, osteogenic, and myogenic differentiation. Results Here we show for the first time that hFTs, which are discarded after some gynecological procedures, are a rich additional source of MSCs, which we designated as human tube MSCs (htMSCs). Conclusion Human tube MSCs can be easily isolated, expanded in vitro, present a mesenchymal profile and are able to differentiate into muscle, fat, cartilage and bone in vitro. PMID:19538712

    Objective To compare the efficacy and safety of the intraocular lens (IOL)-shell procedure versus conventional phacoemulsification for the surgical treatment of dense cataracts. Methods Eighty eyes with dense nuclear cataracts were enrolled in a prospective, randomized controlled study. Patients were assigned to two groups. In Group I, the IOL was traditionally implanted after all nuclear fragments were completely removed, and in Group II, the IOL was innovatively implanted in the bag before the last residual nuclear fragment was removed. This novel adjusted surgical procedure, named the “IOL-shell technique”, features use of the IOL as a protective barrier rather than simply as a refractive alternative, and it is conceptually different from the traditional step-by-step procedure. Clinical examinations, including uncorrected visual acuity, central corneal thickness (CCT), temporal clear corneal incision thickness and corneal endothelial cell density, were carried out. Results The inter-group difference in temporal corneal thickness was found to be of no statistical significance at any of the visits. Compared to eyes in Group I, those in Group II were shown to have significantly less corneal endothelial cell loss on both the 7th and 30th day following surgery. At 7 days after surgery, the mean corneal endothelial cell loss in Group II was 10.29%, compared to 14.37% in Group I (P<0.05). The mean endothelial cell loss measured on postoperative day 30 was 16.88% in Group II compared to 23.32% in Group I (P<0.05). On the 1st day after surgery, the mean CCT of eyes in Group II was significantly smaller compared to Group I (Group I vs. Group II: 19.42% vs. 13.50%, P<0.05). Conclusions Compared to conventional phacoemulsification, the IOL-shell technique was shown to be a relatively safer procedure without compromised efficiency for dense cataracts, and it caused less corneal endothelial cell loss and milder postoperative corneal edema (Clinical Trials Identifier: NCT

  3. Possible pathogenetic roles of abdominal surgery in irritable bowel syndrome.

    2011-04-01

    Recently, a plethora of studies have reported that irritably bowel syndrome (IBS) patients have increased incidences of abdominal surgeries, mainly gut surgeries. This high incidence of surgeries highlights the fact that the surgery was done because diagnosis of IBS was not suspected in them. It is then a matter of inquisitiveness as to why the diagnosis of IBS was missed in so many patients. Lack of clinical diagnostic sophistication could be one of the reasons. However, inspite of these facts, it has never been documented that the typical IBS like picture was present in these patients before surgery. Mostly, the preoperative complaints in negative appendectomy patients have been atypical pain syndromes. Thus we should also take into account the possibility that the typical IBS symptom profile was not present in these patients before surgery and that the surgical intervention could have resulted in subsequent development of complete picture of IBS. Infact, in one study, various surgical procedures were known to precede IBS symptoms, where they have also been conceptualized as one of the stressors which could lead to IB. Seeing from the other perspective, the etiological understanding of IBS in medical literature is still so preliminary that we have only been able to enumerate some possible factors. In such a scenario, we need to explore in detail the events which occur frequently in IBS patients, like abdominal surgery. Here, we hypothesize that any abdominal surgical intervention could itself be a reason for development of IBS. We provide evidences from literature in favor of two such possible mechanisms through which any abdominal surgical procedure could act resulting in development of IBS. In addition, we present the report of follow-up of 4 of our own patients where we specifically inquired about IBS before the appendectomy, which turned out to be negative. After 6 months of the followup, the patients developed symptoms which were diagnosable as IBS. PMID

    Background Lung cancer is one of the most prevalent malignancies worldwide. The number of anatomic lung cancer resections performed via video-assisted thoracoscopic surgery (VATS) is growing rapidly. Staplers are widely used in VATS procedures, but there is limited clinical data regarding how they might affect performance and postoperative outcomes, including air leak. This clinical trial assessed the use of a powered stapler in VATS lung resection, with a primary study endpoint being occurrence and duration of air leak and prolonged air leak (PAL). Methods Data was collected from a single arm, multi-center study in Chinese patients receiving VATS wedge resection or lobectomy. Intra-operative data included surgery duration; cartridge selection for ligation/transection of bronchus, major vessels, and lung parenchyma; staple line interventions; blood loss; and device usage. Post-operative data included air leak assessments, chest tube duration, length of hospital stay, and adverse events (AEs). Results A total of 94 procedures across four institutions in China were included in the final analysis: 15 wedge resections, 74 lobectomies, and five wedge resections followed by lobectomies. Post-operative air leak occurred in five (5.3%) patients who had lobectomy procedures, with PAL in one (1.1%) patient. Sites were generally consistent relative to cartridge use by tissue type. The incidence of stapler firings requiring surgical interventions was seven out of 550 (1.3%). Surgeons participating in the study were satisfied with the articulation and overall usability of the stapler. Conclusions The powered staplers make the VATS procedure easier for the surgeons and have achieved intra- and post-operative patient outcomes comparable to those previously reported. PMID:27162678

    While laparoscopic surgery can be performed using small skin incisions, any resected specimen must still be able to fit through these opening. For procedures, such as cholecystectomies and appendectomies, this is not usually a problem; however, for large specimens such as bowel or large tumors, this becomes problematic. Currently, the standard technique is to attempt piecemeal removal of the specimen or enlarge one of the laparoscopic incisions, effectively creating a mini laparotomy. Creating a larger incision adds many of the drawbacks of open laparotomy and should be avoided whenever possible. In this article, we present a new technique of combining the repair of an inguinal hernia, umbilical hernia with a duodenal tumor resection in order to extract the specimen through the inguinal hernia orifice.

    Suburethral tapes are placed “tension-free” below the urethra. Several studies reported considerable differences of the distance between urethra and tape. These distances ranged from 1 to 10 mm amongst different patients. This either caused urethral obstruction or had no effect on urinary incontinence. Therefore, we decided to standardize the procedure by placing a Hegar dilator of 8-millimeter diameter in the urethra and another Hegar dilator of 4-millimeter diameter between the urethra and the tape during transobturator tape placement. Using that simple technique, which we named “TOT 8/4,” we observed that 83% of the tapes were placed in the desired distance between 3 and 5 millimeters below the urethra. PMID:26981532

    Carrying out invasive procedures in animals requires the administration of anesthesia. Xenon gas offers advantages as an anesthetic agent compared with other agents, such as its protection of the brain and heart from hypoxia-induced damage. The high cost of xenon gas has limited its use as an anesthetic in animal experiments, however. The authors designed and constructed simple boxes for the induction and maintenance of xenon gas and isoflurane anesthesia in small rodents in order to minimize the amount of xenon gas that is wasted. While using their anesthesia delivery system to anesthetize pregnant mice undergoing caesarean sections, they measured the respiratory rates of the anesthetized mice, the survival of the pups and the percentages of oxygen and carbon dioxide within the system to confirm the system's safety.

    Lactate is known to be an indicator of neurological impairment during aortic aneurysm surgery. It is suggested that cerebrospinal fluid removed during such surgery could provide useful information in this regard. Medical professionals find the prospect of online detection of such analytes exciting, as current practice is time consuming and leads to multiple invasive procedures. Advancing from the current laboratory based analysis techniques to online methods could provide the basis for improved treatment regimes, better quality of care, and enhanced resource efficiency within hospitals. Accordingly, this article considers the use of a low power fluidic system with embedded electromagnetic wave sensor to detect varying lactate concentrations. Results are promising over the physiological range of 0 - 20 mmol/L with a calibration curve demonstrating an R2 value > 0.98.

    Eighty healthy children, between the ages of 2 and 7 years, undergoing dental procedures were monitored with a pulse oximeter for changes in arterial oxygen saturation. The children were randomly allocated into 4 groups in this double-blind study. Three groups received rectal midazolam, and the other group a placebo (saline) as premedication 30 min prior to induction of anesthesia. Group A children received midazolam 0.25 mg/kg, Group B 0.35 mg/kg and Group C 0.45 mg/kg. The results from this trial show no statistical significant difference between the treatment groups as to the effect on either systolic or diastolic blood pressure, respiration, or pulse rates at either pre- or post-sedation levels. However, the oxygen saturation levels for groups B and C differed significantly from those of the placebo groups 30 minutes after premedication (P = 0.0259). PMID:2097908

    The operative results of 59 wrist ganglions over a ten-year period are reported. The mean follow-up time was 65 months (range: 6-133). The indication for operation was pre-operative pain in 68% of cases (40 ganglions) and cosmetic deformity in 32% of cases (19 ganglions). There were six recurrences (10%) at a mean duration of 40 months post-operatively (range: 5-70). There was no statistical differences between recurrences comparing dorsal versus volar ganglions using the chi-squared analysis. Two occult recurrences were detected on follow-up ultrasound examination giving an overall recurrence rate of 14%. Despite 92% of patients being satisfied with the operative procedure, there were 16 patients (28%) who had either persistent pain, limitation of function, were unsatisfied or had a recurrence. These results show that treatment of a simple ganglion is more than just a minor operation. PMID:11301508

    Condylar hyperplasia is an overdevelopment of the condyle, which may manifest unilaterally or bilaterally. This pathological condition can lead to facial asymmetry, malocclusion, and dysfunction of the temporomandibular joint. The etiology and pathogenesis of condylar hyperplasia remain uncertain, but it has been suggested that its etiology may be associated with hormonal factors, trauma, and hereditary hypervascularity, affecting both genders. The diagnosis is made by clinical examination, and radiological imaging, and additionally, bone scintigraphy, is a fundamental resource for determining whether the affected condyle shows active growth. Patients with active condylar hyperplasia management have better results when they are subjected to the high condylectomy procedure. The authors report a case in a 20-year-old female subject with unilateral active condylar hyperplasia who was treated by high condylectomy. The patient has been followed up for 4 years without signs of recurrence and with good functional stability of the occlusion. PMID:23851829

    Mycotic aneurysms of the abdominal aorta are uncommon, but potentially lethal problems. Clinical subtleties may suggest their presence, but in the past, definitive diagnosis has been dependent on surgical exploration or autopsy findings. A case is presented in which 67-gallium citrate abdominal scanning localized the site of sepsis in an abdominal aortic aneurysm and allowed for prompt and successful surgical therapy. This noninvasive technique is recommended as a adjunct in the diagnosis of mycotic abdominal aortic aneurysms.

    Background: Image intensifiers have become popular due to the concept of minimally invasive surgeries leading to decreasing invasiveness, decreased operative time, and less morbidity. The drawback, however, is an increased risk of radiation exposure to surgeon, patient and theatre staff. These exposures have been of concern due to their potential ability to produce biological effects. The present study was embarked upon to analyse the amount of radiation received by orthopedic surgeons in India using standard precautionary measures and also to bring awareness about the use of image intensifier safety in everyday practice. Materials and Methods: Twelve right-handed male orthopedic surgeons (4 senior consultants, 5 junior consultants and 3 residents) were included in a three month prospective study for radiation exposure measurement with adequate protection measures in all procedures requiring C Arm fluoroscopy. Each surgeon was provided with 5 Thermo Luminescent Dosimeter (TLD) badges which were tagged at the level of neck, chest, gonads and both wrists. Operative time and exposure time of each procedure was recorded. Exposure dose of each badge at the end of the study was obtained and the results were analysed. Results: Mean radiation exposure to all the parts were well within permissible limits. There was a significantly positive correlation between the exposure time and the exposure dose for the left wrist (r=0.735, p<0.01) and right wrist (r=0.58, p<0.05). The dominant hand had the maximum exposure overall. Conclusion: Orthopaedic surgeons are not classified radiation workers. The mean exposure doses to all parts of the body were well within permissible limits. Nothing conclusive, however, can be said about the stochastic effects (chance effects like cancers). Any amount of radiation taken is bound to pose an additional occupational hazard. It is thus desirable that radiation safety precautions should be taken and exposures regularly monitored with at least one

    This study evaluates X-ray exposure in patient undergoing abdominal extra-vascular interventional procedures by means of Digital Imaging and COmmunications in Medicine (DICOM) image headers and Monte Carlo simulation. The main aim was to assess the effective and equivalent doses, under the hypothesis of their correlation with the dose area product (DAP) measured during each examination. This allows to collect dosimetric information about each patient and to evaluate associated risks without resorting to in vivo dosimetry. The dose calculation was performed in 79 procedures through the Monte Carlo simulator PCXMC (A PC-based Monte Carlo program for calculating patient doses in medical X-ray examinations), by using the real geometrical and dosimetric irradiation conditions, automatically extracted from DICOM headers. The DAP measurements were also validated by using thermoluminescent dosemeters on an anthropomorphic phantom. The expected linear correlation between effective doses and DAP was confirmed with an R(2) of 0.974. Moreover, in order to easily calculate patient doses, conversion coefficients that relate equivalent doses to measurable quantities, such as DAP, were obtained. PMID:26211013

Our article provides an overview of the different types of surgical airways. This article provides a comprehensive review of the main types of surgical airways, relevant anatomy, necessary equipment, indications and contraindications, preparation and positioning, technique, complications, and tips for management. It is important to remember that the placement of a surgical airway is a lifesaving procedure and should be considered in any setting when one “cannot intubate, cannot ventilate”. PMID:24741501

    OBJECTIVE. A review was performed to investigate the frequency of occurrence and outcome of patients who have retained surgical sponges. METHODS. Closed case records from the files of the Medical Professional Mutual Insurance Company (ProMutual, Boston, MA) involving a claim of retained surgical sponges were reviewed for a 7-year period. RESULTS. Retained sponges occurred in 40 patients, comprising 48% of all closed claims for retained foreign bodies. A falsely correct sponge count after an abdominal procedure was documented in 76% of these claims. Ten percent of claims involved vaginal deliveries and minor non-body cavity procedures, for which no sponge count was performed. Total indemnity payments were $2,072,319, and defense costs were $572,079. In three cases, the surgeon was deemed responsible by the court despite the nursing staff's admitting liability and evidence presented that the surgeon complied completely with the standard of care. A wide range of indemnity payments was made despite a remarkable similarity of outcome in the patients studied. CONCLUSIONS. Despite the rarity of the reporting of a retained surgical sponge, this occurrence appears to be encountered more commonly than generally is appreciated. Operating teams should ensure that sponges be counted for all vaginal and any incisional procedures at risk for retaining a sponge. In addition, the surgeon should not unquestioningly accept correct count reports, but should develop the habit of performing a brief but thorough routine postprocedure wound/body cavity exploration before wound closure. The strikingly similar outcome for most patients would argue for a standardized indemnity payment being made without the need for adversarial legal procedures. PMID:8678622

    Outcomes of abdominal aortic aneurysm (AAA) repair have improved in the 2 decades since the emergence of endovascular aneurysm repair (EVAR). However, EVAR is considered a contraindication for shaggy aorta because of the high risk of shower embolization. Recently, statins have been implicated in preventing embolization in patients with shaggy aorta via its pleiotropic effects, including atheroma reduction and coronary artery stabilization. We selected pitavastatin, a statin with potent effects, discovered and developed by a Japanese company because it has shown excellent pleiotropic effects on atheromatous arteries in the Japanese population. A randomized comparison study of dose-dependent effects of pitavastatin in patients with AAA with massive atheromatous aortic thrombus (PROCEDURE study) has begun. PROCEDURE has an enrollment goal of up to 80 patients with AAA with massive aortic atheroma (excluding intrasac atheroma), randomly allocated into 2 groups receiving pitavastatin at a dose of 1 or 4 mg/day. The endpoints of the PROCEDURE study include change in atheroma volume, major adverse events related to shower embolization after aneurysm repair, and lipid-lowering effects. When complete, results of the PROCEDURE study should provide objective evidence to use statins preoperatively for AAA with massive aortic atheroma. PMID:23641286

    Intravenous propofol anesthesia is better than inhalational anesthesia for otologic surgery, but cost and intraoperative movement make this technique prohibitive. This study compares a propofol sandwich anesthetic with a total propofol or inhalational anesthetic for otologic surgery to determine which produces the best perioperative conditions and least expense. One hundred twenty patients undergoing ear surgery were randomly chosen to receive an anesthetic with either isoflurane (INHAL), total propofol (TPROP), or propofol used in conjunction with isoflurane (PSAND). Postoperative wakeup and the incidence and severity of nausea, vomiting, and pain were compared among groups. Antiemetic administration and discharge times from recovery and the hospital were also compared. The groups were similar, but anesthesia times were longer in the INHAL group. Emergence from anesthesia after PSAND or TPROP was more rapid than after INHAL. Recovery during the next 24 hours was associated with less nausea and vomiting with PSAND than with INHAL. The cost of the PSAND anesthetic was similar to that of INHAL, and both were less than TPROP. PSAND anesthesia may be similar to TPROP and better than INHAL for otologic procedures. PSAND was less expensive than TPROP and produced a similar recovery profile and antiemetic effect in the 24-hour period after surgery. PMID:10064647

    The objective of this study was to evaluate an Er:YAG laser (ErL) application for periodontal regenerative surgery in angular bone defects at nine sites in six patients. Debridement was thoroughly performed using a combination of curettage with a Gracey-type curette and ErL irradiation at a panel setting of 70 mJ/pulse and 20 Hz with sterile saline spray. After applying an enamel matrix derivative and autogenous bone grafting, ErL was used to form a blood clot coagulation on the grafted bone surface at 50 mJ/pulse and 20 Hz without water spray for approximately 30 seconds. Twelve months after surgery the mean probing depth had improved from 6.2 mm to 2.0 mm, the mean clinical attachment level had reduced from 7.5 mm to 3.4 mm, and bleeding on probing had improved from (+) to (-). Mean intrabony defect depth decreased from 6.0 mm before surgery to 1.0 mm 12 months after surgery. A novel procedure for periodontal regenerative surgery applying ErL irradiation for thorough decontamination during debridement as well as blood coagulation following autogenous bone grafting seems to have achieved favorable and stable healing of periodontal pockets with significant clinical improvement and desirable regeneration of angular bone defects, including one-wall defects.

    External abdominal hernia occurs when abdominal organs or tissues leave their normal anatomic site and protrude outside the skin through the congenital or acquired weakness, defects or holes on the abdominal wall, including inguinal hernia, umbilical hernia, femoral hernia and so on. Acute incarcerated hernia is a common surgical emergency. With advances in minimally invasive devices and techniques, the diagnosis and treatment have witnessed major changes, such as the use of laparoscopic surgery in some cases to achieve minimally invasive treatment. However, strict adherence to the indications and contraindications is still required. PMID:25489584

    Summary Background An important negative factor of EVAR is the radiation acquired during long-lasting procedures. The aim of the study was to document the radiation doses of EVAR and to discuss potential reasons for prolongation of radiological procedures. Material/Methods Dose-area product (DAP) (Gy cm2) and air kerma (AK) (Gy) obtained during EVAR from 92 patients were analyzed retrospectively in regards to body mass index (BMI), angulations of aneurysm neck, length of aneurysm neck and occurrence of tortuosity of iliac arteries. Results Total AK for fluoroscopy differed significantly between normal BMI (373 mGy) and BMI 25–29.9 (1125 mGy) or BMI >30 (1085 mGy). Iliac artery tortuosities >45° and short aneurysm necks caused higher doses of total AK (1097 mGy and 1228 mGy, respectively) than iliac artery tortuosities <45° and long aneurysm necks (605 mGy and 720 mGy, respectively). Conclusions The main factors contributing to a high radiation dose being acquired by patients during EVAR are: BMI >25, tortuosity of iliac arteries >45° and short aneurysm necks. PMID:22037751

    2013-01-01

    Coarctation of the abdominal aorta is extremely rare. It generally involves a long segment of the descending aorta and causes uncontrolled and unexplainable hypertension in children. The therapeutic choice is very challenging because acute and chronic complications are reported for both the surgical and the percutaneous approaches. The two reported cases of abdominal coarctation were treated primarily and successfully through the use of covered stents. Three covered stents were implanted in two children. No complication occurred with either procedure. At this writing, an 18-month follow-up assessment has found the patients in good health with no restenosis at the coarctation site. Covered stent implantation in children with abdominal coarctation is a feasible, safe, and effective procedure. It provides adequate relief of symptoms and reduces the risk of aneurysm formation. To avoid covering important side branches with polytetrafluoroethylene, this type of procedure must be preceded by precise study of the aorta and its branches. PMID:23515761

    The U.S. Occupational Safety and Health Administration (OSHA) estimates that half a million health-care workers are exposed to laser surgical smoke each year. The purpose of this study was to establish a methodology to (1) estimate emission rates of laser-generated air contaminants (LGACs) using an emission chamber, and to (2) perform a screening study to differentiate the effects of three laser operational parameters. An emission chamber was designed, fabricated, and assessed for performance to estimate the emission rates of gases and particles associated with LGACs during a simulated surgical procedure. Two medical lasers (Holmium Yttrium Aluminum Garnet [Ho:YAG] and carbon dioxide [CO2]) were set to a range of plausible medical laser operational parameters in a simulated surgery to pyrolyze porcine skin generating plume in the emission chamber. Power, pulse repetition frequency (PRF), and beam diameter were evaluated to determine the effect of each operational parameter on emission rate using a fractional factorial design. The plume was sampled for particulate matter and seven gas phase combustion byproduct contaminants (benzene, ethylbenzene, toluene, formaldehyde, hydrogen cyanide, carbon dioxide, and carbon monoxide): the gas phase emission results are presented here. Most of the measured concentrations of gas phase contaminants were below their limit of detection (LOD), but detectable measurements enabled us to determine laser operation parameter influence on CO2 emissions. Confined to the experimental conditions of this screening study, results indicated that beam diameter was statistically significantly influential and power was marginally statistically significant to emission rates of CO2 when using the Ho:YAG laser but not with the carbon dioxide laser; PRF was not influential vis-a-vis emission rates of these gas phase contaminants.

    Background: Abdominal wall hernias are very common diseases encountered in surgical practice. Groin hernia is the commonest type of abdominal wall hernias. There are several methods of hernia repair but tension-free repair (usually with mesh) offers the least recurrent rate. Aim: To describe the clinical profile of anterior abdominal wall hernias and our experience in the surgical management of identified hernias Method: The project was a retrospective study of all patients with abdominal wall hernia presenting into surgical divisions of University College Hospital Ibadan during a 6 year period (January 2008 to December 2013). Relevant information was retrieved from their case notes and analysed. Results: The case records of 1215 (84.7%) patients out of 1435 were retrieved. Elective surgery was done in 981(80.7%) patients while 234 (19.3%) patients had emergency surgery. There were 922 (84.8%) groin hernias and post-operative incisional hernia accounted for 9.1% (111) of the patients. About half (49.1%) of those with incisional hernia were post obstetric and gynaecologic procedure followed by post laparotomy incisional hernias 16 (14%) and others (23.5%). The ratio of inguinal hernia to other types in this study is 3:1. Hollow viscus resection and emergency surgery were predictors of wound infection statistically significant in predicting wound infection (P < 0.001). Peri-operative morbidity/mortality at 28 days post operation was documented in 113 patients (12.1%). One year recurrence rate of groin hernia was 2.1%. Conclusion: The pattern of presentation and management of anterior wall hernias are still the same compared with the earlier study in this hospital. New modality of treatment should be adopted as the standard choice of care. Abdominal wall hernias are very common clinical presentation. Modified Bassini repair was the preferred method of repair due to its simplicity. Mesh repair is becoming more common in recent time but high cost and initial non

    Objective To examine, in the Veterans Health Administration (VHA), the relation between surgical volume and outcome in eight commonly performed operations of intermediate complexity. Summary Background Data In multihospital health care systems such as VHA, consideration is often given to closing low-volume surgical services, with the assumption that better surgical outcomes are achieved in hospitals with larger surgical volumes. Literature data to support this assumption in intermediate-complexity operations are either limited or controversial. Methods The VHA National Surgical Quality Improvement Program data on nonruptured abdominal aortic aneurysmectomy, vascular infrainguinal reconstruction, carotid endarterectomy (CEA), lung lobectomy/pneumonectomy, open and laparoscopic cholecystectomy, partial colectomy, and total hip arthroplasty were used. Pearson correlation, analysis of variance, mixed effects hierarchical logistic regression, and automatic interaction detection analysis were used to assess the association of annual procedure/specialty volume with risk-adjusted 30-day death (and stroke in CEA). Results Eight major surgical procedures (68,631 operations) were analyzed. No statistically significant associations between procedure or specialty volume and 30-day mortality rate (or 30-day stroke rate in CEA) were found. Conclusions In VHA hospitals, the procedure and surgical specialty volume in eight prevalent operations of intermediate complexity are not associated with risk-adjusted 30-day mortality rate from these operations, or with the risk-adjusted 30-day stroke rate from CEA. Volume of surgery in these operations should not be used as a surrogate for quality of surgical care. PMID:10493488

    Introduction This analysis explores the association between elements of surgical efficiency in voluntary medical male circumcision (VMMC), quality of surgical technique, and the amount of time required to conduct VMMC procedures in actual field settings. Efficiency outcomes are defined in terms of the primary provider’s time with the client (PPTC) and total elapsed operating time (TEOT). Methods Two serial cross-sectional surveys of VMMC sites were conducted in Kenya, Republic of South Africa, Tanzania and Zimbabwe in 2011 and 2012. Trained clinicians observed quality of surgical technique and timed 9 steps in the VMMC procedure. Four elements of efficiency (task-shifting, task-sharing [of suturing], rotation among multiple surgical beds, and use of electrocautery) and quality of surgical technique were assessed as explanatory variables. Mann Whitney and Kruskal Wallis tests were used in the bivariate analysis and linear regression models for the multivariate analyses to test the relationship between these five explanatory variables and two outcomes: PPTC and TEOT. The VMMC procedure TEOT and PPTC averaged 23–25 minutes and 6–15 minutes, respectively, across the four countries and two years. The data showed time savings from task-sharing in suturing and use of electrocautery in South Africa and Zimbabwe (where task-shifting is not authorized). After adjusting for confounders, results demonstrated that having a secondary provider complete suturing and use of electrocautery reduced PPTC. Factors related to TEOT varied by country and year, but task-sharing of suturing and/or electrocautery were significant in two countries. Quality of surgical technique was not significantly related to PPTC or TEOT, except for South Africa in 2012 where higher quality was associated with lower TEOT. Conclusions SYMMACS data confirm the efficiency benefits of task-sharing of suturing and use of electrocautery for decreasing TEOT. Reduced TEOT and PPTC in high volume setting did

  11. Large Abdominal Wall Endometrioma Following Laparoscopic Hysterectomy

    PubMed Central

    Borncamp, Erik; Mehaffey, Philip; Rotman, Carlos

    2011-01-01

    Background: Endometriosis is a common condition in women that affects up to 45% of patients in the reproductive age group by causing pelvic pain. It is characterized by the presence of endometrial tissue outside the uterine cavity and is rarely found subcutaneously or in abdominal incisions, causing it to be overlooked in patients with abdominal pain. Methods: A 45-year-old woman presented with lower abdominal pain 2 years following a laparoscopic supracervical hysterectomy. She was found to have incidental cholelithiasis and a large abdominal mass suggestive of a significant ventral hernia on CT scan. Results: Due to the peculiar presentation, surgical intervention took place that revealed a large 9cm×7.6cm×6.2cm abdominal wall endometrioma. Conclusion: Although extrapelvic endometriosis is rare, it should be entertained in the differential diagnosis for the female patient who presents with an abdominal mass and pain and has a previous surgical history.

    There is a growing trend to perform off-bypass surgical ablation for atrial fibrillation (AF) because it is perceived to be safer and more effective than the Cox-Maze procedure with cardiopulmonary bypass (CPB) support. In this systematic review, we compared three minimally invasive stand-alone surgical ablation procedures for AF: the endocardial Cox-Maze procedure, epicardial surgical ablation and a hybrid epicardial surgical and catheter-based endocardial ablation procedure (hybrid procedure). Relevant studies were identified in MEDLINE and the Cochrane Database of Systematic Reviews according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. From 565 initial studies, 37 were included in this review. The total number of patients across all studies was 1877 (range 10-139). Two studies reported on endocardial Cox-Maze procedures (n = 145), 26 reported on epicardial surgical ablation (n = 1382) and 9 reported on hybrid surgical ablation (n = 350). For minimally invasive Cox-Maze, epicardial and hybrid groups, operative mortality rates were 0, 0.5 and 0.9%, perioperative permanent pacemaker insertion rates were 3.5, 2.7 and 1.5%, incidence of conversion to median sternotomy was 0, 2.4 and 2.5%, and reoperation for bleeding was 1.0, 1.5 and 2.2%, with mean length of stay (days) of 5.4, 6.0 and 4.6, respectively. At 12 months, rates of sinus rhythm restoration were 93, 80 and 70%, and sinus restoration without anti-arrhythmic medications was 87, 72 and 71%, for Cox-Maze, epicardial and hybrid procedures, respectively. Of the three procedures, the minimally invasive Cox-Maze procedure with CPB support was most effective for the treatment of stand-alone AF and had important safety advantages in conversion to sternotomy and major bleeding. The minimally invasive Cox-Maze procedure with CPB support also demonstrated the potential for a higher success rate 12 months following the procedure. PMID:25567961

    Introduction Mondor disease (MD), a superficial thrombophlebitis of the thoraco-epigastric veins and their confluents is rarely reported in the literature. The superior epigastric vein is the most affected vessel but involvement of the inferior epigastric vessels or their branches have also been described. There is no universal consensus on treatment in the literature but most authors suggest symptomatic treatment with non-steroid anti-inflammatory drugs (NSAIDs). Case report We report the case of a marathon runner who presented with right iliac fossa pain mimicking the clinical symptomatology of an acute appendicitis. The history and the calculated Alvarado score were not in favor of an acute appendicitis. This situation motivated multiple investigations and we finally arrived at the diagnosis of MD. Discussion Acute appendicitis (AA) is the most common cause of surgical emergencies and one of the most frequent indications for an urgent abdominal surgical procedure around the world. In some cases, right lower quadrant pain remains unclear in spite of US, CT scan, and exclusion of urological and gynecological causes, thus we need to think of some rare pathologies like MD. Conclusion MD is often mentioned in the differential diagnosis of breast pathologies but rarely in abdominal pain assessment. It should be mentioned in the differential diagnosis of the right lower quadrant pain when the clinical presentation is unclear and when acute appendicitis has been excluded. Awareness of MD can avoid misdiagnosis and decrease extra costs by sparing unnecessary imaging. PMID:26803533

    The aim of the study is to evaluate the therapeutic effect of a new surgical procedure, dumbbell-form resection (DFR), for hilar cholangiocarcinoma (HCCA) with severe jaundice. In DFR, liver segments I, IVb, and partial V above the right hepatic pedicle are resected.Hemihepatectomy is recognized as the preferred procedure; however, its application is limited in HCCAs with severe jaundice.Thirty-eight HCCA patients with severe jaundice receiving DFR and 70 receiving hemihepatectomy from January 2008 to January 2013 were included. Perioperative parameters, operation-related morbidity and mortality, and post-operative survival were analyzed.A total of 21.1% patients (8/38) in the DFR group received percutaneous transhepatic biliary drainage (PTBD), which was significantly <81.4% (57/70) in the hemihepatectomy group. The TBIL was higher in the DFR group at operation (243.7 vs 125.6 μmol/L, respectively). The remnant liver volume was significantly higher after DFR. The operation-related morbidity was significantly lower after DFR than after hemihepatectomy (26.3% vs 48.6%, respectively). None of the patients died during the perioperative period after DFR, whereas 3 died after hemihepatectomy. There was no difference in margin status, histological grade, lymph-node involvement, and distant metastasis between the 2 groups. The 1-, 3-, and 5-year survival rates after DFR (68.4%, 32.1%, and 21.4%, respectively) showed no significant difference with those after hemihepatectomy (62.7%, 34.6%, and 23.3%, respectively). Kaplan-Meier analysis indicated that overall survival and recurrence after DFR demonstrated no significant difference compared with hemihepatectomy.DFR appears to be feasible for selected HCCA patients with severe jaundice. However, its indications should be restricted. PMID:26765439

    Aneurismal dilatation of the remaining thoracic aorta after ascending aortic interposition grafting for type 'A' aortic dissection is not uncommon. For such complex cases, one treatment option is total arch replacement and elephant trunk procedure with the Sienna(TM) collared graft (Vascutek, Inchinnan, UK) technique followed by a staged thoracic endovascular aortic repair (TEVAR). The video illustrates our technique in a 56-year-old man with an extensive aortic arch and descending thoracic aortic dissecting aneurysm. For the 'open' procedure femoral arterial and venous cannulation was used along with systemic cooling and circulatory arrest at 22 °C. Upon circulatory arrest, the aortic arch was incised and antegrade cerebral perfusion achieved via selective cannulation to the right brachiocephalic and left common carotid artery, keeping flow rates at 10-15 mL/kg/min and perfusion pressure at 50-60 mmHg. Arch replacement with an elephant trunk component was then performed and after completion of the distal aortic anastomosis antegrade perfusion via a side-arm in the graft was started and the operation completed using a variation of the 'sequential' clamping technique to maximize cerebral perfusion. The second endovascular stage was performed two weeks after discharge. Two covered stents were landing from the elephant trunk to the distal descending thoracic aorta, to secure the distal landing a bare stent of was placed to cover the aorta just distal to the origin of the celiac axis. The left subclavian artery was embolised with fibre coils. Post TEVAR angiogram showed no endoleak Although re-operative total arch replacement and elephant trunk procedure and subsequent TEVAR remained a challenging procedure, we believe excellent surgical outcome can be achieved with carefully planned operative strategy.

    The excision of the choledochal cyst with bile drainage through intestinal conduit is a standard operative procedure in the surgical management of choledochal cysts. During the last eight years five patients have been treated with this operation at the University Children's Hospital in Zagreb. All the patients were girls aged from two months to twelve years. The classical triad of pain, jaundice and abdominal mass was observed in only one patient, an eight-year-old girl. The only symptom in infancy was jaundice. Diagnosis was made by abdominal ultrasound, bibliography, CT scan with hepatotropic contrast and in older children by ERCP. Four cysts were type Todani I, and one cyst was Todani type II. The complete excision of the choledochal cyst with the Roux-Y jejunal conduit without antireflux valve was performed. There was neither operative morbidity nor mortality. Three months postoperatively the control ultrasonography and liver laboratory tests were without abnormalities. The routine control which followed did not show episodes of cholangitis, lithiasis, lipid malabsorption, blood clotting abnormalities or growth failure. The complete excision of the cyst with Roux-Y hepaticoenterostomy is an operative treatment with good results in infancy and childhood. PMID:10932533

    An increased use of bioprosthetic heart valves has stimulated an interest in possible transcatheter options for bioprosthetic valve failure given the high operative risk. The encouraging results of transcatheter aortic valve implantation in high-risk surgical candidates with native disease have led to the development of the transcatheter valve-in-valve (VIV) procedures for failed bioprostheses. VIV procedures are unique in many ways, and there is an increased need for multimodality imaging in a team-based approach. The echocardiographic approach to VIV procedures has not previously been described. In this review, we summarize key echocardiographic requirements for optimal patient selection, procedural guidance, and immediate post-procedural assessment for VIV procedures. PMID:26271092

    Surgical procedures for spinal lipoma or tethered spinal cord after myelomeningocele (MMC) repair are often difficult and complicated, because the anatomical structures can be deformed in complex and unpredictable ways. Imaging helps the surgeon understand the patient's spinal anatomy. Whereas two-dimensional images provide only limited information for surgical planning, three-dimensional (3D) reconstructed computed tomography (CT)-magnetic resonance (MR) fusion images produce clearer representations of the spinal regions. Here we describe simple and quick methods for obtaining 3D reconstructed CT-MR fusion images for preoperative planning of surgical procedures using the iPlan(®) cranial (BrainLAB AG, Feldkirchen, Germany) neuronavigation software. 3D CT images of the vertebral bone were combined with heavily T(2)-weighted MR images of the spinal cord, lipoma, cerebrospinal fluid (CSF) space, and nerve root through a process of fusion, segmentation, and reconstruction of the 3D images. We also used our procedure called "Image Overlay" to directly project the 3D reconstructed image onto the body surface using an LED projector. The final reconstructed 3D images took 10-30 minutes to obtain, and provided the surgeon with a representation of the individual pathological structures, so enabled the design of effective surgical plans, even in patients with bony deformity such as scoliosis. None of the 19 patients treated based on our 3D reconstruction method has had neurological complications, except for CSF leakage. This 3D reconstructed imaging method, combined with Image Overlay, improves the visual understanding of complicated surgical situations, and should improve surgical efficiency and outcome.

    Textiloma is the inadvertent retention of a textile foreign body on the surgical site. It is a rare complication of surgery but which carries severe consequences for both patients and surgeons in terms of morbi-mortality and medico-legal procedures respectively. We herein report the case of an abdominal textiloma in a 42 year old woman who underwent a total abdominal hysterectomy for symptomatic leiomyomas. We also depict the errors that led to this mishap in a tertiary hospital in Yaounde (Cameroon). The textiloma was recognized six weeks after the causative surgery and removed by laparotomy without further complications. PMID:24876905

    Ventral hernias (VHs) are abnormal openings in the anterior abdominal wall that are common side effects of surgical intervention. Repair of VHs is the most commonly performed procedure by general surgeons worldwide, but VH repair outcomes are not particularly encouraging (with recurrence rates up to 43%). A variety of open and laparoscopic techniques are available for hernia repair, and the specific technique used is ultimately driven by surgeon preference and experience. Despite routine acquisition of computed tomography (CT) for VH patients, little quantitative information is available on which to guide selection of a particular approach and/or optimize patient-specific treatment. From anecdotal interviews, the success of VH repair procedures correlates with hernia size, location, and involvement of secondary structures. Herein, we propose an image labeling protocol to segment the anterior abdominal area to provide a geometric basis with which to derive biomarkers and evaluate treatment efficacy. Based on routine clinical CT data, we are able to identify inner and outer surfaces of the abdominal walls and the herniated volume. This is the first formal presentation of a protocol to quantify these structures on abdominal CT. The intra- and inter rater reproducibilities of this protocol are evaluated on 4 patients with suspected VH (3 patients were ultimately diagnosed with VH while 1 was not). Mean surfaces distances of less than 2mm were achieved for all structures.

    Background The World Health Organization (WHO) and the Joint United Nations Program on HIV/AIDS promote MC (male circumcision) as a key HIV prevention strategy where HIV prevalence and incidence are high and MC prevalence is low. In Zimbabwe, to achieve the 1.26 million circumcisions needed to be performed by 2015 to achieve optimal MC coverage, a new approach was needed. The primary objective of the current trial was to assess the performance (safety, procedure time, and cost) of the PrePex device compared to forceps-guided surgical circumcision. Methods and Findings This Phase II, randomized, open-label trial in Zimbabwe involved healthy, non-circumcised adult male volunteers who were randomly assigned to the PrePex device (n = 160) or surgical arm (n = 80). Three doctors and 4 nurses, all certified on both circumcision methods, performed the procedures. The PrePex device procedure involves a plastic ring with a rubber O-ring that necrotizes the foreskin to facilitate easy and minimally invasive removal. Total procedure time was the primary endpoint. Adverse event (AE) data were also gathered for 90 days post-procedure. All 80 participants in the surgical arm and 158 participants in the PrePex arm achieved complete circumcision. The total procedure time for the PrePex device was approximately one-third of the total surgical procedure (4.8 minutes, Standard Deviation [SD]: 1.2 versus 14.6 minutes; SD: 4.2; p<0.00001). There were 2 AEs for 2 participants (rate of 1.3%, 95% Confidence Interval: 0.0025–4.53%), which were resolved with simple intervention. The AEs were device related, including 1 case of pain leading to device removal and 1 case of removal of the device. Conclusions The trial supports previous studies’ conclusions that the PrePex procedure is safe, quick, easy to apply, and effective in terms of procedure time as an alternative to traditional surgical circumcision. The PrePex device has great potential for use in overburdened health systems and in

    Abdominal infections are an important challenge for the intensive care physician. In an era of increasing antimicrobial resistance, selecting the appropriate regimen is important and, with new drugs coming to the market, correct use is important more than ever before and abdominal infections are an excellent target for antimicrobial stewardship programs. Biomarkers may be helpful, but their exact role in managing abdominal infections remains incompletely understood. Source control also remains an ongoing conundrum, and evidence is increasing that its importance supersedes the impact of antibiotic therapy. New strategies such as open abdomen management may offer added benefit in severely ill patients, but more data are needed to identify its exact role. The role of fungi and the need for antifungal coverage, on the other hand, have been investigated extensively in recent years, but at this point, it remains unclear who requires empirical as well as directed therapy.

    Objective To systematically evaluate the evidence across surgical specialties as to whether staples or sutures better improve patient and provider level outcomes. Design A systematic review of systematic reviews and panoramic meta-analysis of pooled estimates. Results Eleven systematic reviews, including 13,661 observations, met the inclusion criteria. In orthopaedic surgery sutures were found to be preferable, and for appendicial stump sutures were protective against both surgical site infection and post surgical complications. However, staples were protective against leak in ilecolic anastomosis. For all other surgery types the evidence was inconclusive with wider confidence intervals including the possibly of preferential outcomes for surgical site infection or post surgical complication for either staples or sutures. Whilst reviews showed substantial variation in mean differences in operating time (I2 94%) there was clear evidence of a reduction in average operating time across all surgery types. Few reviews reported on length of stay, but the three reviews that did (I2 0%, including 950 observations) showed a non significant reduction in length of stay, but showed evidence of publication bias (P-value for Egger test 0.05). Conclusions Evidence across surgical specialties indicates that wound closure with staples reduces the mean operating time. Despite including several thousand observations, no clear evidence of superiority emerged for either staples or sutures with respect to surgical site infection, post surgical complications, or length of stay.

    Introduction Facial transplantation represents one of the most complicated scenarios in craniofacial surgery because of skeletal, aesthetic, and dental discrepancies between donor and recipient. However, standard off-the-shelf vendor computer-assisted surgery systems may not provide custom features to mitigate the increased complexity of this particular procedure. We propose to develop a computer-assisted surgery solution customized for preoperative planning, intraoperative navigation including cutting guides, and dynamic, instantaneous feedback of cephalometric measurements/angles as needed for facial transplantation. Methods We developed the Computer-Assisted Planning and Execution (CAPE) workstation to assist with planning and execution of facial transplantation. Preoperative maxillofacial computed tomography (CT) scans were obtained on 4 size-mismatched miniature swine encompassing 2 live face-jaw-teeth transplants. The system was tested in a laboratory setting using plastic models of mismatched swine, after which the system was used in 2 live swine transplants. Postoperative CT imaging was obtained and compared with the preoperative plan and intraoperative measures from the CAPE workstation for both transplants. Results Plastic model tests familiarized the team with the CAPE workstation and identified several defects in the workflow. Live swine surgeries demonstrated utility of the CAPE system in the operating room, showing submillimeter registration error of 0.6 ± 0.24 mm and promising qualitative comparisons between intraoperative data and postoperative CT imaging. Conclusions The initial development of the CAPE workstation demonstrated integration of computer planning and intraoperative navigation for facial transplantation are possible with submillimeter accuracy. This approach can potentially improve preoperative planning, allowing ideal donor-recipient matching despite significant size mismatch, and accurate surgical execution. PMID:24406592

    Background: GlideScope (GS) is a video laryngoscope that allows a real-time view of the glottis and endotracheal intubation. It provides a better view of the larynx without the need for alignment of the airway axes. Aim: This prospective randomized comparative study is designed to compare the intubation time, hemodynamic response, and complications associated with intubation using a GS or Macintosh laryngoscope (ML) in adult subjects undergoing elective surgical procedures. Materials and Methods: Sixty American Society of Anesthesiologists physical status 1–2 patients were included in this prospective randomized comparative study. Patients were randomized to be intubated using either a GS or an ML. The primary outcome measure was the intubation time. The secondary outcome measures were the hemodynamic response to intubation and the incidence of mucosal injury. Statistical Analysis: Mean and standard deviation were calculated for different parameters under the study. The observed results were analyzed using Student's t-test for quantitative data and Z-test of proportions. P<0.05 was considered statistically significant. Results: Intubation time was longer in GS group (45.7033 ± 11.649 s) as compared to ML (27.773 ± 5.122 s) P< 0.0001 with 95% confidence interval (95% CI) −13.2794 to −22.5806. GS provided better Cormack and Lehane laryngoscopic view (P = 0.0016 for grade 1 view) with 95% CI −0.1389 to −0.5951. GS group exhibited more laryngoscopic response than ML group with more increase in blood pressure and heart rate, but the difference was not statistically significant. More cases of mucosal trauma were documented in GS group. Conclusion: Use of GS to facilitate intubation led to better glottic view but took a longer time to achieve endotracheal intubation. GS was associated with more hemodynamic response to intubation and mucosal injury in comparison with an ML. PMID:27212755

    Although most frequently presenting with lower abdominal pain, appendicitis, colitis, and diverticulitis can cause pain throughout the abdomen and can cause peritoneal and retroperitoneal symptoms. Evaluation and management of lower intestinal disease requires a nuanced approach by the emergency physician, sometimes requiring computed tomography, ultrasonography, MRI, layered imaging, shared decision making, serial examination, and/or close follow-up. Once a presumed or confirmed diagnosis is made, appropriate treatment is initiated, and may include surgery, antibiotics, and/or steroids. Appendicitis patients should be admitted. Diverticulitis and inflammatory bowel disease can frequently be managed on an outpatient basis, but may require admission and surgical consultation. PMID:27133242

    Abdominal aortic aneurysms (AAAs) are a common but asymptomatic disease that has high susceptibility to rupture. Current therapeutic options are limited to surgical procedures because no pharmacological approaches have been proven to decrease either expansion or rupture of human AAAs. The current dearth of effective medical treatment is attributed to insufficient understanding of the mechanisms underlying the initiation, propagation and rupture of AAAs. This review will emphasize recent advances in mechanistic studies that may provide insights into potential pharmacological treatments for this disease. While we primarily focus on recent salient findings, we also discuss mechanisms that continue to be controversial depending on models under study. Despite the progress on exploring mechanisms of experimental AAAs, ultimate validation of mechanisms will require completion of prospective double-blinded clinical trials. In addition, we advocate increased emphasis of collaborative studies using animal models and human tissues for determination of mechanisms that explore expansion and rupture of existing AAAs.

    Risk factors associated with surgical infections are related to many events that modulate the immune system and affect the surgical procedure. The aim of this study was to determine the influence of low CD4+ lymphocyte counts in 24 patients with human immunodeficiency virus (HIV) undergoing abdominal surgery. Blood samples were obtained, and the lymphocyte population was evaluated perioperatively, as was the nutritional status of the patient. All the patients received selective antibiotic prophylaxis depending on the surgical procedure performed: (1) clean surgery: splenectomies (n = 8); (2) clean-contaminated: cholecystectomy and biliary tract surgery (n = 8); and (3) contaminated: appendectomy (n = 8). Depending on their CD4 count, two groups were formed: one with 200 to 500 cells/ml (n = 11) and the other with < 200 cells/ml (n = 13). When surgical infection was suspected, surgical drainage and microbiologic cultures were undertaken. For statistical evaluation of the groups ANOVA and the chi-square test were used; p < 0.05 was considered significant. Altogether 14 patients (58.3%) had a wound infection, and the mean (+/- SD) CD4 count in those patients was decreased (221.7 +/- 75.1) compared with that of the 10 patients in the uneventful group (386 +/- 81.2). Surgical infection rates were 50% for clean procedures, 62.5% for clean-contaminated procedures, and 62.5% for contaminated surgery. The group of patients with CD4 counts of < 200 cell/ml had an increased incidence of surgical infection, regardless of the type of surgery (p = 0.002). Thus the surgical infection rates with HIV patients undergoing abdominal surgery are dramatically increased. The CD4 and subsequently depressed neutrophil populations increase the risk of surgical infection during major procedures regardless of the type of surgery performed. PMID:9673546

    Recurrent abdominal pain in the left fossa often mimicking attacks of subileus is described in a woman aged 48 with extensive adhesions caused by multiple surgical procedures. Repeated examinations with conventional abdominal radiography and barium meals were negative with regard to mechanical intestinal obstruction. A cystic lesion varying in size from 2 to 8 cm in diameter was seen adjacent to the left ovary on repeat US examinations and also on CT. Pain episodes were sometimes correlated to increasing size of the lesion which was finally thought to be either a peritoneal inclusion cyst (fluid trapped between pelvic adhesions) or, as was finally confirmed at surgery, a true ovarian cyst (corpus luteum cyst) similarly trapped.

    This study was carried out in order to determine the effect of various surgical procedures on lymphedema in a rat model. In 26 adult male Sprague-Dawley rats, randomly divided into four groups, surgical lymphedema was created in the left hind limbs.: The control group had no drainage, Group 1 had a conventional Kinmonth operation, Group 2 had a modified Kinmonth operation using the greater omentum and Group 3 had autologous lymph node capsule-venous anastomosis with lymph node transfer. Circumference measurement was performed to calculate percent difference and circumferential reduction rate. In Groups 2 and 3, patent blue violet was injected to identify lymphatics. In all groups, hematoxylin-eosin (H-E) and 5'-nucleotidase stainning were done to evaluate lymphatics histopathologically. The percent difference and the circumferential reduction rate respectively showed the smallest and largest values in Group 2. A significant difference was found between the control group and Group 2 (p < 0.05). Lymphatic vessels were shown by patent blue violet injection in Groups 2 and 3. H-E and 5'-nucleotidase staining revealed patency of lymphatics. A modified Kinmonth procedure using the greater omentum was the most effective procedure for early lymphedema in a rat model and autologous lymph node capsule-venous anastomosis with lymph node transfer was effective for lymph draining in certain conditions, so it may assist in elucidating surgical treatment of lymphedema.

    Colorectal carcinoma (KCR) is the commonest malignancy in male patients and the second commonest in female patients in the Czech Republic. During 1990-2006, 1162 patients with colorectal carcinomas were operated in the FTNsP (Faculty Thomayer Hospital) Surgical Clinic. 212 patients aged between 39 to 94 y.o.a.(the median of 70 y.o.a) were managed urgently for acute abdominal illness. In this group of urgently managed patients, the mortality rate was 17% and the morbidity rate was 38%. Future prospects of any colorectal carcinoma patient with acute abdominal illness depend on the procedure's radicality, which is limited by the overall patient's condition. The preoperative care aims to improve the patient's overall condition to such a degree, to allow for surgery fulfilling principles of oncosurgical radicality. According to this report's data, such urgent surgical procedures do not result in increased mortality or morbidity rates, compared to these in planned procedures, and show the best results in this patient group.

    Repair of abdominal wall defects is a challenge for all general surgeons and a variety of methods have been described in the past. Traditionally, primary suture repair was shown to have a high recurrence rate in long-term follow-up studies. Herniorrhaphies that apply a large prosthetic mesh are appear to have a lower failure rate, but extensive dissection of soft tissue contributes to an increased incidence of wound infections and wound-related complications. The method of laparoscopic incisional hernia repair was developed in the early 1990s. This technique is based on the same physical and surgical principles as the open underlay procedure. The laparoscopic intraperitoneal onlay mesh (IPOM) technique and mesh materials were developed further in subsequent years, and there have been numerous reports on successful use of the IPOM technique even for extremely large hernia openings in obese and elderly patients. Reduced surgical trauma and lower infection and recurrence rates are key advantages of the minimally invasive repair. Therefore, this operation has increased in popularity promising shorter hospital stay, improved outcome, and fewer complications than traditional open procedures. PMID:20965866

    The number of breast reconstruction procedures has been increasing in recent years. One of the suggested treatment methods is breast reconstruction with a pedicled skin and muscle TRAM flap (transverse rectus abdominis muscle - TRAM). Surgical incisions performed during a cholecystectomy procedure may be located in the areas significant for flap survival. The aim of this paper is to present anatomical changes in abdominal walls secondary to pedicled skin and muscle (TRAM) flap breast reconstruction, which influence the planned access in cholecystectomy procedures. The authors present 2 cases of cholecystectomy performed due to cholelithiasis in female patients with a history of TRAM flap breast reconstruction procedures. The first patient underwent a traditional method of surgery 14 days after the reconstruction due to acute cholecystitis. The second patient underwent a laparoscopy due to cholelithiasis 7 years after the TRAM procedure. In both cases an abdominal ultrasound scan was performed prior to the operation, and surgical access was determined following consultation with a plastic surgeon. The patient who had undergone traditional cholecystectomy developed an infection of the postoperative wound. The wound was treated with antibiotics, vacuum therapy and skin grafting. After 7 weeks complete postoperative wound healing and correct healing of the TRAM flap were achieved. The patient who had undergone laparoscopy was discharged home on the second postoperative day without any complications. In order to plan a safe surgical access, it is necessary to know the changes in the anatomy of abdominal walls following a pedicled TRAM flap breast reconstruction procedure. PMID:25337177

    Introduction Laparoscopic repair is becoming an increasingly popular alternative in the treatment of abdominal wall hernias. In spite of numerous studies evaluating this technique, indications for laparoscopic surgery have not been established. Similarly, implant selection and fixation techniques have not been unified and are the subject of scientific discussion. Aim To assess whether there is a consensus on the management of the most common ventral abdominal wall hernias among recognised experts. Material and methods Fourteen specialists representing the boards of European surgical societies were surveyed to determine their choice of surgical technique for nine typical primary ventral and incisional hernias. The access method, type of operation, mesh prosthesis and fixation method were evaluated. In addition to the laparoscopic procedures, the number of tackers and their arrangement were assessed. Results In none of the cases presented was a consensus of experts obtained. Laparoscopic and open techniques were used equally often. Especially in the group of large hernias, decisions on repair methods were characterised by high variability. The technique of laparoscopic mesh fixation was a subject of great variability in terms of both method selection and the numbers of tackers and sutures used. Conclusions Recognised experts have not reached a consensus on the management of abdominal wall hernias. Our survey results indicate the need for further research and the inclusion of large cohorts of patients in the dedicated registries to evaluate the results of different surgical methods, which would help in the development of treatment algorithms for surgical education in the future.

    OBJECTIVE: Patients undergoing abdominal surgery are at risk for pulmonary complications. The principal cause of postoperative pulmonary complications is a significant reduction in pulmonary volumes (FEV1 and FVC) to approximately 65-70% of the predicted value. Another frequent occurrence after abdominal surgery is increased intra-abdominal pressure. The aim of this study was to correlate changes in pulmonary volumes with the values of intra-abdominal pressure after abdominal surgery, according to the surgical incision in the abdomen (superior or inferior). METHODS: We prospectively evaluated 60 patients who underwent elective open abdominal surgery with a surgical time greater than 240 minutes. Patients were evaluated before surgery and on the 3rd postoperative day. Spirometry was assessed by maximal respiratory maneuvers and flow-volume curves. Intra-abdominal pressure was measured in the postoperative period using the bladder technique. RESULTS: The mean age of the patients was 56±13 years, and 41.6% 25 were female; 50 patients (83.3%) had malignant disease. The patients were divided into two groups according to the surgical incision (superior or inferior). The lung volumes in the preoperative period showed no abnormalities. After surgery, there was a significant reduction in both FEV1 (1.6±0.6 L) and FVC (2.0±0.7 L) with maintenance of FEV1/FVC of 0.8±0.2 in both groups. The maximum intra-abdominal pressure values were similar (p = 0.59) for the two groups. There was no association between pulmonary volumes and intra-abdominal pressure measured in any of the groups analyzed. CONCLUSIONS: Our results show that superior and inferior abdominal surgery determines hypoventilation, unrelated to increased intra-abdominal pressure. Patients at high risk of pulmonary complications should receive respiratory care even if undergoing inferior abdominal surgery. PMID:25029580

    Objective To detail robotic procedure development and clinical applications for mitral valve, biliary, and gastric reflux operations, and to implement a multispecialty robotic surgery training curriculum for both surgeons and surgical teams. Summary Background Data Remote, accurate telemanipulation of intracavitary instruments by general and cardiac surgeons is now possible. Complex technologic advancements in surgical robotics require well-designed training programs. Moreover, efficient robotic surgical procedures must be developed methodically and safely implemented clinically. Methods Advanced training on robotic systems provides surgeon confidence when operating in tiny intracavitary spaces. Three-dimensional vision and articulated instrument control are essential. The authors’ two da Vinci robotic systems have been dedicated to procedure development, clinical surgery, and training of surgical specialists. Their center has been the first United States site to train surgeons formally in clinical robotics. Results Established surgeons and residents have been trained using a defined robotic surgical educational curriculum. Also, 30 multispecialty teams have been trained in robotic mechanics and electronics. Initially, robotic procedures were developed experimentally and are described. In the past year the authors have performed 52 robotic-assisted clinical operations: 18 mitral valve repairs, 20 cholecystectomies, and 14 Nissen fundoplications. These respective operations required 108, 28, and 73 minutes of robotic telemanipulation to complete. Procedure times for the last half of the abdominal operations decreased significantly, as did the knot-tying time in mitral operations. There have been no deaths and few complications. One mitral patient had postoperative bleeding. Conclusion Robotic surgery can be performed safely with excellent results. The authors have developed an effective curriculum for training teams in robotic surgery. After training, surgeons

    The physiological and psychological stress that brain tumor patients undergo during the entire surgical experience can considerably affect several aspects of their hospitalization. The purpose of this study was to examine the effects of live music therapy on quality of life indicators, amount of medications administered and length of stay for persons receiving elective surgical procedures of the brain. Subjects (N = 27) were patients admitted for some type of surgical procedure of the brain. Subjects were randomly assigned to either the control group receiving no music intervention (n = 13) or the experimental group receiving pre and postoperative live music therapy sessions (n = 14). Anxiety, mood, pain, perception of hospitalization or procedure, relaxation, and stress were measured using a self-report Visual Analog Scale (VAS) for each of the variables. The documented administration of postoperative pain medications; the frequency, dosage, type, and how it was given was also compared between groups. Experimental subjects live and interactive music therapy sessions, including a pre-operative session and continuing with daily sessions until the patient was discharged home. Control subjects received routine hospital care without any music therapy intervention. Differences in experimental pretest and posttest scores were analyzed using a Wilcoxon Matched-Pairs Signed-Rank test. Results indicated statistically significant differences for 4 of the 6 quality of life measures: anxiety (p = .03), perception of hospitalization (p = .03), relaxation (p = .001), and stress (p = .001). No statistically significant differences were found for mood (p > .05) or pain (p > .05) levels. Administration amounts of nausea and pain medications were compared with a Two-Way ANOVA with One Repeated Measure resulting in no significant differences between groups and medications, F(1, 51) = 0.03; p > .05. Results indicate no significant differences between groups for length of stay (t = .97

    Introduction: Surgical procedures are still the golden standard option in the treatment of liver cystic echinococcosis. However, minimal invasive technics like percutaneous drainage are rising trends. We aimed to compare the efficacy of surgical and percutaneous options in the treatment of liver hydatidosis in an endemic area. Methods: Patients who underwent surgical or percutaneous procedures for hydatid disease between January 2007 and December 2012 were retrospectively evaluated. Recurrence rates, hospital stay time, and related factors were analyzed. Results: There were 44 (35.5%) male and 80 (64.5%) female patients in this study. Eighty two patients (Group I) had undergone surgery (66.1%) and 42 patients (Group II) had undergone percutaneous drainage (33.9%). The mean cyst size was 7.28 ± 2.51 cm in Group I and 8.76 ± 3.30 cm in Group II. Nine recurrences (7.3%) were detected during study. Five of the recurrences were in Group II (11.9%) and four (4.9%) of them were in Group I. The mean length of hospital stay of all patients was 5.42 ± 3.16 days. Discussion: Percutaneous drainage techniques can be a good alternative to surgery in selected patients. In complicated cases like cystobiliary fistula, surgery is superior to percutaneous approaches. The hospital stay time, recurrence rate and postoperative complications were not enhanced when compared to percutaneous treatment in our study. Despite all controversy about the low morbidity after percutaneous treatment, surgical approach is still a preferable option in patients with liver hydatidosis when it is performed by experienced surgeons.

    Isolated dissection of an abdominal aortic branch is a rare entity, and previous reports regarding the condition have been based only on small case-series studies. Using a national inpatient database in Japan, we describe the clinical features of patients with isolated celiac, superior mesenteric, splenic, and hepatic artery dissections (ICAD, ISMAD, ISAD, and IHAD). We extracted data on inpatients who were diagnosed with ICAD, ISMAD, ISAD, or IHAD from the Japanese diagnosis procedure combination database, including patients' age and sex, putative risk factors (smoking status and specific comorbidities), treatments (blood transfusion, transcatheter arterial embolization (TAE) and surgical procedures), and outcomes (in-hospital complications and death). Among 18.3 million inpatients in the database between July 2010 and March 2013, we identified 276 ICAD, 715 ISMAD, 23 ISAD and 11 IHAD. The percentage of males was 78-92 %, and the mean age was 54.7-56.8 years. Hypertension was seen in 48-65, and 35-65 % were smokers. Fourteen in-hospital deaths were identified in total. In the ICAD group, splenectomy was performed in one patient and TAE was performed in 26 patients. In the ISMAD group, 16 patients received surgical intervention. Most patients with isolated dissection of an abdominal aortic branch were treated conservatively, while a small percentage required TAE or open surgery. A small proportion of dissections resulted in death. PMID:25421008

    Abdominal pain is a commonplace reason for surgical consultation in the emergency department and is the the most common symptom which the digestive surgeon on-call must evaluate. He must understand the pathophysiologic basis of visceral pain and referred pain in order to appreciate its diverse manifestations. Abdominal pain can stem from many causes intestinal and non-intestinal, medical and surgical. Evaluation and management in the emergency department must be rapid and pragmatic; clinical history and physical examination should define the gravity of the case, direct the first diagnostic procedures and complementary examinations, and guide the therapeutic direction. Ultrasonography is a quick and effective diagnostic procedure in the diagnosis of biliary, urologic, and gynecologic pathologies; it can be useful for other digestive problems as well. The new generation spiral CT scanner gives excellent definition of digestive and vascular pathologies. The initial evaluation and management of the acute abdomen may determine the prognosis of the patient; it should lead to prompt symptomatic relief and to a well-directed treatment appropriate to the diagnosis.

    Despite ongoing advances in medical technology, postoperative infections and infectious complications continue to be a significant cause of morbidity and mortality. Surgical trauma and prophylactic antibiotics disrupt the balance of the intestinal microbiota and barrier function of the gut, potentiating an enhanced inflammatory response and further immune system depression. With the increasing costs of health care and emergence of multidrug-resistant bacteria, alternative approaches must be explored. Many clinical studies have demonstrated that the use of probiotics, prebiotics, or a combination of both (synbiotics) as a part of innovative strategies can improve outcomes of elective abdominal and gastrointestinal surgical procedures. It has been demonstrated that probiotics play a role in gut barrier improvement and immunomodulation. However, it is evident that additional research is needed including larger, multicenter, randomized controlled trials to validate the safety and efficacy of their use in surgical patients. The purpose of this article is to discuss background of probiotic use in abdominal/gastrointestinal surgery, risk and benefits, clinical relevance for health care providers, and further implications for research.

    Objective We sought to evaluate and compare the outcomes of different surgical protocols for papillary thyroid cancer (PTC) located in the isthmus in a retrospective intention-to-treat analysis. Patients and methods The data of 3,068 patients who received thyroidectomy due to thyroid cancer in our center were reviewed. Of these, 103 patients had a dominant carcinoma located in the isthmus. Various baseline and tumor characteristics and surgical outcomes were evaluated and compared with respect to the different surgical protocols (85 cases with total thyroidectomy and 18 cases with less-than-total thyroidectomy). Univariate and multivariate analyses were performed to identify resected patients who developed recurrence with isthmic PTC. Results The postoperative complication rates were comparable between the two groups (17.6% versus 11.1%, P=0.500). Although the total thyroidectomy group showed a much higher rate (P=0.004) and number (P<0.001) of parathyroidectomies, long-term follow-up indicated that parathyroid autotransplantation did not significantly damage the function of the parathyroid (P>0.05). Tumor recurrence was observed in five patients, including two patients in the total thyroidectomy group and three patients in the less-than-total thyroidectomy group; the tumor recurrence rate in the total thyroidectomy group was significantly lower than that in the less-than-total thyroidectomy group (P=0.040). Univariate and multivariate analyses indicated less-than-total thyroidectomy as a risk factor for tumor recurrence in PTC cases with tumors located at the isthmus (hazard ratio: 1.870, 95% confidence interval: 1.320–2.218, P<0.001). Conclusion Our findings indicate that total thyroidectomy is an appropriate initial surgical protocol for isthmic PTC due to the lower recurrence rate, comparable postoperative complication rate, and parathyroid function recovery.

    19 children were diagnosed with abdominal cysts of different origin in the Surgical Unit of the Department of Pediatrics, Medical University of Pécs, Hungary between 2010 and 2013. The authors discuss the details of representative cases of a parovarial cyst, an intestinal duplication, and an omental cyst with emphasis on the clinical symptoms, diagnostic tools, and surgical interventions. The authors conclude that abdominal cysts often cause mild symptoms only, and they are discovered accidentally by ultrasound imaging performed for other reasons. In some cases, the cyst can cause severe complaints or even acute abdomen requiring emergency surgery. Laporoscopy may be a valuable method both in diagnosis and surgical therapy. Abdominal CT or MRI are not required in the majority of the patients. PMID:26552027

    Pelvic organ prolapse is an extremely common condition, with approximately 12% of women requiring surgical correction over their lifetime. This manuscript reviews the most recent literature regarding the comparative efficacy of various surgical repair techniques in the treatment of advanced stage pelvic organ prolapse. Uterosacral ligament suspension has similar anatomic and subjective outcomes when compared to sacrospinous ligament fixation at 12 months and is considered to be equally effective. The use of transvaginal mesh has been shown to be superior to native tissue vaginal repairs with respect to anatomic outcomes but at the cost of a higher complication rate. Minimally invasive sacrocolpopexy appears to be equivalent to abdominal sacrocolpopexy (ASC). Robot-assisted sacrocolpopexy (RSC) and laparoscopic sacrocolpopexy (LSC) appear as effective as abdominal sacrocolpopexy, however, prospective studies of comparing long-term outcomes of ASC, LSC, and RSC in relation to health care costs is paramount in the near future. Surgical correction of advanced pelvic organ prolapse can be accomplished via a variety of proven techniques. Selection of the correct surgical approach is a complex decision process and involves a multitude of factors. When deciding on the most suitable surgical intervention, the chosen route must be individualized for each patient taking into account the specific risks and benefits of each procedure.

    This nine-chapter book gives an overview of the integrated approach to abdominal imaging. Chapter 1 provides an introduction to the physics used in medical imaging; chapter 2 is on the selection of imaging modalities. These are followed by four chapters that deal, respectively, with plain radiography, computed tomographic scanning, sonography, and nuclear imaging, as applied to the abdomen. Two chapters then cover contrast material-enhanced studies of the gastrointestinal (GI) tract: one focusing on technical considerations; the other, on radiologic study of disease processes. The final chapter is a brief account of different interventional procedures.

    This work is focused on the detailed computer simulation of the key stages involved in a shape memory alloy (SMA) osteosynthesis bone stapling procedure. To this end, a recently developed three-dimensional constitutive SMA material model was characterized from test data of three simple uniaxial-isothermal-tension experiments for powder metallurgically processed nickel-rich NiTi (PM/NiTi-P) material. The calibrated model was subsequently used under the complex, thermomechanical loading conditions involved in the surgical procedure using the body-temperature-activated PM/NiTi-P bone staple. Our aim here is to assess the immediate and post-surgical performance characteristics of the stapling operation using the material model. From this study: (1) it was found that adequate compressive forces were developed by the PM/NiTi-P bone staple, with the tendency of this force to even increase under sustained thermal loading due to the intrinsic "inverse relaxation phenomena" in the SMA material, (2) the simulation results correlated well with those from experimental measurements, (3) the body-temperature-activated PM/NiTi-P staple was proved to be clinically viable, providing a stable clamping force needed for speedy coaptation of the fractured bones, and (4) these realistic assessments crucially depend on the use of suitable and comprehensive SMA material models.

GALEN-IN-USE is the current phase which applied the modelling and the tools to the development or the updating of coding systems for surgical procedures in different national coding centre co-operating within the European Federation of Coding Centre (EFCC) to create a multilingual knowledge repository for multicultural Europe. NCAM (Nomenclature Commune des Actes Médicaux) is the new French multipurpose coding system for surgical procedures. The labels are processed from the intermediate dissections to the Grail representation and the natural language generation by the electronically related Medical Informatics research centres network of Saint Etienne, Manchester, Geneva and Nijmegen. The national coding centre is able to retrieve the initial labels with different categories of concepts, to compare the professional language proposed by expert clinicians to the French generated controlled vocabulary and to finalize the linguistic labels of the coding system in relation with the meanings of the conceptual system structure.

    Each year, over 500,000 adenotonsillectomies (AT), mostly for the treatment of pediatric obstructive sleep apnea (OSA) are performed in the US in children under 15 years of age. No definitive study, however, has been yet conducted that has rigorously evaluated the effectiveness of AT for not only improving sleep disordered breathing, but also for improving clinically relevant outcomes, such as neurocognitive function, behavior, and quality of life. The Childhood Adenotonsillectomy Trial (CHAT) was designed to assess neuropsychological and health outcomes in children randomized to receive early AT (eAT) as compared to Watchful Waiting with Supportive Care (WWSC). Important secondary goals of the study are to evaluate outcomes in subgroups defined by obesity and race. This paper addresses key elements in the design and implementation of a controlled trial for a widely used “standard practice” surgical intervention in a pediatric population, that include establishment of standardized data collection procedures across sites for a wide variety of data types, establishment of equipoise, and approaches for minimizing unblinding of selected key personnel. The study framework that was established should provide a useful template for other pediatric controlled studies or other studies that evaluate surgical interventions.

    A 53-year-old woman with liver cirrhosis and hepatocellular carcinoma underwent living donor liver transplantation. After transplantation, her hemoglobin and hematocrit levels decreased to 6.3 g/dl and 18.5%, respectively, during the course of 3 days. A contrast-enhanced abdominal computed axial tomography (CAT) scan showed a hemoperitoneum in the right perihepatic space with no evidence of abdominal wall hematoma or pseudoaneurysm formation. An angiogram of the deep circumflex iliac artery (DCIA) showed extravasation of contrast media along the surgical drain, which had been inserted during the transplantation procedure. Transcatheter embolization of the branches of the DCIA was successfully performed using N-butyl cyanoacrylate.

    A surgical technique currently used in the treatment of Abdominal Aortic Aneurysms (AAA) is the Endovascular Aneurysm Repair (EVAR). This minimally invasive procedure involves inserting a prosthesis in the aortic vessel that excludes the aneurysm from the bloodstream. The stent, once in place acts as a false lumen for the blood current to travel down, and not into the surrounding aneurysm sac. This procedure, therefore, immediately takes the pressure off the aneurysm, which thromboses itself after some time. Nevertheless, in a long term perspective, different complications such as prosthesis displacement or bloodstream leaks into or from the aneurysmatic bulge (endoleaks) could appear causing a pressure elevation and, as a result, increasing the danger of rupture. The purpose of this work is to explore the application of image registration techniques to the visual detection of changes in the thrombus in order to assess the evolution of the aneurysm. Prior to registration, both the lumen and the thrombus are segmented

    Background In 1998 a formal process using the criteria of safety, effectiveness and cost-effectiveness (evidence based medicine) on the introduction and use of new medical procedures was implemented in Australia. As part of this process an expert panel, the Medical Services Advisory Committee (MSAC) was set up. This paper examines the effectiveness of this process based on the original criteria, that is, evidence based medicine. Method The data for this analysis was sourced primarily from that made available in the public domain. The MSAC web site provided Minutes from MSAC meetings; Annual Reports; Assessment and Review reports; Progress status; and Archived material. Results The total number of applications submitted to the MSAC has been relatively low averaging approximately only fourteen per year. Additionally, the source of applications has quickly shifted to the medical devices, equipment and diagnostic industry as being the major source of applications. An overall average time for the processing of an application is eighteen months. Negative recommendations were in most cases based on insufficient clinical evidence rather than clinical evidence that clearly demonstrated a lack of clinical effectiveness. It was rare for a recommendation, either positive or negative, to be based on cost-effectiveness. Conclusion New medical procedures are often the result of a process of experimentation rather than formally conducted research. Affordability and the question of who should pay for the generation, collection and analysis of the clinical evidence is perhaps the most difficult to answer. This is especially the case where the new procedure is the result of a process of experimentation with an old procedure. A cost-effective way needs to be found to collect acceptable levels of evidence proving the clinical effectiveness of these new procedures, otherwise the formal processes of evaluation such as that used by the Australian MSAC since 1998 will continue to run the

    OBJECTIVE Hospital readmission rate is increasingly used as a quality outcome measure after surgery. The purpose of this study was to establish, using a national database, the baseline readmission rates and risk factors for patient readmission after pediatric neurosurgical procedures. METHODS The American College of Surgeons National Surgical Quality Improvement Program-Pediatric database was queried for pediatric patients treated by a neurosurgeon between 2012 and 2013. Procedures were categorized by current procedural terminology (CPT) code. Patient demographics, comorbidities, preoperative laboratory values, operative variables, and postoperative complications were analyzed via univariate and multivariate techniques to find associations with unplanned readmissions within 30 days of the primary procedure. RESULTS A total of 9799 cases met the inclusion criteria, 1098 (11.2%) of which had an unplanned readmission within 30 days. Readmission occurred 14.0 ± 7.7 days postoperatively (mean ± standard deviation). The 4 procedures with the highest unplanned readmission rates were CSF shunt revision (17.3%; CPT codes 62225 and 62230), repair of myelomeningocele > 5 cm in diameter (15.4%), CSF shunt creation (14.1%), and craniectomy for infratentorial tumor excision (13.9%). The lowest unplanned readmission rates were for spine (6.5%), craniotomy for craniosynostosis (2.1%), and skin lesion (1.0%) procedures. On multivariate regression analysis, the odds of readmission were greatest in patients experiencing postoperative surgical site infection (SSI; deep, organ/space, superficial SSI, and wound disruption: OR > 12 and p < 0.001 for each). Postoperative pneumonia (OR 4.294, p < 0.001), urinary tract infection (OR 4.262, p < 0.001), and sepsis (OR 2.616, p = 0.006) also independently increased the readmission risk. Independent patient risk factors for unplanned readmission included Native American race (OR 2.363, p = 0.019), steroid use > 10 days (OR 1.411, p = 0

    Objectives To evaluate the association of frailty, a measure of diminished physiologic reserve, with both major and minor surgical complications among patients undergoing urologic surgery. Materials and Methods Using data from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) from 2007 to 2013, we identified all urologic cases that appeared more than 1000 times in the dataset among patients age 40 and older. Frailty was measured using the NSQIP Frailly Index (FI), a validated measure that includes 11 impairments such as decreased functional status and impaired sensorium. We created multivariable logistic regression models using the NSQIP Frailty Index to assess major and minor complications after surgery. Results We identified 95,108 urologic cases representing 21 urologic procedures. The average frequency of complications per individual was 11.7%, with the most common complications being hospital readmission (6.2%), blood transfusion (4.6%), and urinary tract infection (3.1%). Major and minor complications increased with increasing NSQIP-FI. Frailly remained strongly associated with complications after adjustment for year, age, race, smoking status, and method of anesthesia [adjusted OR 1.74 (95% CI 1.64, 1.85) NSQIP-FI 0.18+]. Increasing NSQIP-FI was associated with increasing frequency of complications within age groups (by decade) up to age 81 and across most procedures. Conclusion Frailty strongly correlates with risk of post-operative complications among patients undergoing urologic surgery. This finding is true within most age groups and across most urologic procedures. PMID:26691588

    Postoperative cognitive dysfunction (POCD) is a debilitating surgical complication, with cardiac surgery patients at particular risk. To gain insight in the mechanisms underlying the higher incidence of POCD after cardiac versus non-cardiac surgery, systemic and central inflammatory changes, alterations in intraneuronal pathways, and cognitive performance were studied after cardiac and abdominal surgery in rats. Male Wistar rats were subjected to ischemia reperfusion of the upper mesenteric artery (abdominal surgery) or the left coronary artery (cardiac surgery). Control rats remained naïve, received anesthesia only, or received thoracic sham surgery. Rats were subjected to affective and cognitive behavioral tests in postoperative week 2. Plasma concentrations of inflammatory factors, and markers for neuroinflammation (NGAL and microglial activity) and the BDNF pathway (BDNF, p38MAPK and DCX) were determined. Spatial memory was impaired after both abdominal and cardiac surgery, but only cardiac surgery impaired spatial learning and object recognition. While all surgical procedures elicited a pronounced acute systemic inflammatory response, NGAL and TNFα levels were particularly increased after abdominal surgery. Conversely, NGAL in plasma and the paraventricular nucleus of the hypothalamus and microglial activity in hippocampus and prefrontal cortex on postoperative day 14 were increased after cardiac, but not abdominal surgery. Both surgery types induced hippocampal alterations in BDNF signaling. These results suggest that POCD after cardiac surgery, compared to non-cardiac surgery, affects different cognitive domains and hence may be more extended rather than more severe. Moreover, while abdominal surgery effects seem limited to hippocampal brain regions, cardiac surgery seems associated with more wide spread alterations in the brain. PMID:26867718

    Objective: To evaluate the outcome of modified Quad procedure in preteen and teen patients with brachial plexus birth palsy. Background: We have previously demonstrated a significant improvement in shoulder abduction, resulting from the modified Quad procedure in children (mean age 2.5 years; range, 0.5–9 years) with obstetric brachial plexus injury. Methods: We describe in this report the outcome of 16 patients (6 girls and 10 boys; 7 preteen and 9 teen) who have undergone the modified Quad procedure for the correction of the shoulder function, specifically abduction. The patients underwent transfer of the latissimus dorsi and teres major muscles, release of contractures of subscapularis pectoralis major and minor, and axillary nerve decompression and neurolysis (the modified Quad procedure). Mean age of these patients at surgery was 13.5 years (range, 10.1–17.9 years). Results: The mean preoperative total Mallet score was 14.8 (range, 10–20), and active abduction was 84° (range, 20°–140°). At a mean follow-up of 1.5 years, the mean postoperative total Mallet score increased to 19.7 (range, 13–25, P < .0001), and the mean active abduction improved to 132° (range, 40°–180°, P < .0003). Conclusion: The modified Quad procedure greatly improves not only the active abduction but also other shoulder functions in preteen and teen patients, as this outcome is the combined result of decompression and neurolysis of the axillary nerve and the release of the contracted internal rotators of the shoulder.

    A robust identification of the instrument currently used by the surgeon is crucial for the automatic modeling and analysis of surgical procedures. Various approaches for intra-operative surgical instrument identification have been presented, mostly based on radio-frequency identification (RFID) or endoscopic video analysis. A novel approach is to identify the instruments on the instrument table of the scrub nurse with a combination of video and weight information. In a previous article, we successfully followed this approach and applied it to multiple instances of an ear, nose and throat (ENT) procedure and the surgical tray used therein. In this article, we present a metric for the suitability of the instruments of a surgical tray for identification by video and weight analysis and apply it to twelve trays of four different surgical domains (abdominal surgery, neurosurgery, orthopedics and urology). The used trays were digitized at the central sterile services department of the hospital. The results illustrate that surgical trays differ in their suitability for the approach. In general, additional weight information can significantly contribute to the successful identification of surgical instruments. Additionally, for ten different surgical instruments, ten exemplars of each instrument were tested for their weight differences. The samples indicate high weight variability in instruments with identical brand and model number. The results present a new metric for approaches aiming towards intra-operative surgical instrument detection and imply consequences for algorithms exploiting video and weight information for identification purposes.

    Background: Preclinical studies have demonstrated that macroporous silk fibroin protein scaffolds are capable of promoting physiologically durable supportive tissue, which favors application of these engineered tissues for clinical implantation. The safety and effectiveness of a long-lasting, transitory, 510(k)-cleared purified silk fibroin biologic scaffold (SBS) are investigated for soft-tissue support and repair of the abdominal wall. Methods: We conducted a multicenter retrospective review of all consecutive patients who underwent abdominal wall soft-tissue reinforcement with an SBS device between 2011 and 2013. Indications, comorbid conditions, surgical technique, complications, and outcomes were evaluated. Results: We reviewed the records of 172 consecutive patients who received an SBS for soft-tissue support. Of those, 77 patients underwent abdominal wall fascial repair, with a mean follow-up of 18.4 ± 7.5 months. Procedures using an SBS included reinforcement of an abdominal-based flap donor site (31.2%), ventral hernia repair (53.2%), and abdominoplasty (15.6%). The overall complication rate was 6.5%, consisting of 2 wound dehiscences, 1 with device exposure, 1 seroma, 1 infection with explantation, and a perioperative bulge requiring reoperation. There were no reports of hernia. Conclusions: Postoperative complication rates after 18 months were low, and most surgical complications were managed nonoperatively on an outpatient basis without mesh removal. To our knowledge, this is the only series to report on a long-lasting, transitory SBS for abdominal wall repair and reinforcement. Procedure-specific outcome studies are warranted to delineate optimal patient selection and define potential device characteristic advantages. PMID:25506529

    We present a rare complication of abdominal compartment syndrome (ACS) in a child undergoing complex urologic reconstruction. A 10-year-old female born with the abdominal wall defect cloacal exstrophy who had previously undergone multiple abdominal procedures then developed findings consistent with ACS following a complex Mitrofanoff procedure. Although intravesical pressures were not documented because of the nature of her reconstruction, her ACS-type findings were (1) abdominal pain, (2) melena, (3) pulmonary hypoinflation, (4) renal insufficiency, (5) tachycardia, and (6) segmental ischemic small bowel. Management consisted of abdominal decompression, segmental bowel resections, and wound vacuum-assisted-closure management. Patient was eventually discharged home. PMID:26921644

    Abstract Regenerative therapies offer attractive alternatives for the treatment of osteochondral defects. Adipose-derived stromal vascular fraction (SVF) cells allow the development of one-step surgical procedures by their abundant availability and high frequency. In this pilot study we evaluated the in vivo safety, feasibility, and efficacy of this concept using scaffolds seeded with freshly isolated (SVF) or cultured adipose stem cells (ASCs), and compared these to their acellular counterparts. Osteochondral defects were created in medial condyles and trochlear grooves in knees of eight goats. Defects were filled with acellular collagen I/III scaffolds or scaffolds seeded with SVF cells or cultured ASCs. Osteochondral regeneration was evaluated after 1 and 4 months by macroscopy, immunohistochemistry, biomechanical analysis, microCT analysis, and biochemistry. After 1 month, no adverse effects were noted. Microscopic, but not macroscopic evaluation showed considerable yet not significant differences, with cell-loaded constructs showing more extensive regeneration. After 4 months, acellular constructs displayed increased regeneration, however, to a lesser degree than cell-treated constructs. The latter exhibited more extensive collagen type II, hyaline-like cartilage, and higher elastic moduli, and their glycosaminoglycan content in the cartilaginous layer better approached native tissue values. Moreover, their defect regions contained higher levels of regenerated, mature subchondral bone with more intense collagen type I staining. SVF cells tended to perform best on all parameters. In summary, this pilot study demonstrated the preclinical safety and feasibility of a one-step surgical procedure for osteochondral defect regeneration. Similar regeneration was found between freshly isolated SVF cells and cultured ASCs. Larger studies with longer follow-up are required to substantiate these findings. PMID:23914338

    Patient: Male, 3-day Final Diagnosis: Ectopic right testis in anterior abdominal wall Symptoms: — Medication: — Clinical Procedure: Testicular ultrasound and MRI abdomen Specialty: Radiology Objective: Unusual clinical course Background: Abnormal testicular descent can either be undescended or, less commonly, ectopic. Most undescended testes complete the course of descent by the first year of life only if these remain in the normal path of descent. The deviation of the testis may occur to an ectopic location during the transinguinal phase. Of the known ectopic sites, the anterior abdominal wall is the rarest site of testicular ectopia and to our knowledge only 3 cases of this nature have been reported in the available literature to date. Case Report: This rare case of testicular ectopia occurred in a 3-day-old boy in whom the right scrotal sac was empty; on abdominal ultrasound, the right testis was found in the subcutaneous tissues of the right antero-lateral abdominal wall. These findings were confirmed on abdominal MRI, where the right testis was seen beneath the skin between the subcutaneous tissues and external oblique aponeurosis. No aponeurotic or muscular defect was appreciable under the abdominal wall. The neonate underwent orchiopexy at the age of 6 months and remained uneventful postoperatively. Conclusions: Preoperative imaging is recommended to detect and confirm the ectopic site as well as the morphology of testis, thereby increasing the chance of surveillance and preservation of an ectopic testis. Imaging can serve as preoperative road mapping to localize the exact site for surgical exploration of an ectopic testis if there is no apparent or palpable swelling over the anterior abdominal wall.

    OBJECTIVE To evaluate hospital administrative data to identify potential surgical site infections (SSIs) following primary elective total hip or knee arthroplasty. DESIGN Retrospective cohort study. SETTING All acute care facilities in Alberta, Canada. METHODS Diagnosis and procedure codes for 6 months following total hip or knee arthroplasty were used to identify potential SSI cases. Medical charts of patients with potential SSIs were reviewed by an infection control professional at the acute care facility where the patient was identified with a diagnosis or procedure code. For SSI decision, infection control professionals used the National Healthcare Safety Network SSI definition. The performance of traditional surveillance methods and administrative data-triggered medical chart review was assessed. RESULTS Of the 162 patients identified by diagnosis or procedure code, 46 (28%) were confirmed as an SSI by an infection control professional. More SSIs were identified following total hip vs total knee arthroplasty (42% vs16%). Of 46 confirmed SSI cases, 20 (43%) were identified at an acute care facility different than their procedure facility. Administrative data-triggered medical chart review with infection control professional confirmation resulted in a 1.1- to 1.7-fold increase in SSI rate compared with traditional surveillance. SSIs identified by administrative data resulted in sensitivity of 90% and specificity of 99%. CONCLUSION Medical chart review for cases identified through administrative data is an efficient supplemental SSI surveillance strategy. It improves case-finding by increasing SSI identification and making identification consistent across facilities, and in a provincial surveillance network it identifies SSIs presenting at nonprocedure facilities.

    We evaluated the effect of LLLT in 68 patients who presented hypoesthesia due to odontological surgery procedures: dental implant surgeries (N=51); extraction of impacted lower third molars (N=10); endodontics in lower first molars (N=7). Lesions treated within 30 days after the nerve injury had occurred were part of the immediate group, and lesions with more than 30 days from the occurrence of the injury were part of the late group. Treatments were carried out with an infrared diode laser of 40 mW-830nm, continuous wave emission, spot size 3 mm2, and a total dosage of 18 joules per session in a contact mode of application, 20 sessions altogether. The efficacy of laser therapy in peripheral nerve regeneration is also related to the degree of the peripheral nerve lesion, and not only to the lesion duration. LLLT resulted in neurosensory functional improvement in both immediate and late treatments of hypoesthesia.

    OBJECTIVE This study aims to describe the frequency of use and reported effectiveness of endoscopic and surgical therapies in patients with CP treated at US referral centers. METHODS Five hundred fifteen patients were enrolled prospectively in the North American Pancreatitis II Study 2, where patients and treating physicians reported previous therapeutic interventions and their perceived effectiveness. We evaluated the frequency and effectiveness of endoscopic (biliary or pancreatic sphincterotomy, biliary or pancreatic stent placement) and surgical (pancreatic cyst removal, pancreatic drainage procedure, pancreatic resection, surgical sphincterotomy) therapies. RESULTS Biliary and/or pancreatic sphincterotomy (42%) were the most commonly attempted endoscopic procedure (biliary stent, 14%; pancreatic stent, 36%; P<0.001). Endoscopic procedures were equally effective (biliary sphincterotomy, 40.0%; biliary stent, 40.8%; pancreatic stent, 47.0%; P=0.34). On multivariable analysis, the presence of abdominal pain (odds ratio, 1.82; 95% 95% confidence interval, 1.15–2.88) predicted endoscopy, whereas exocrine insufficiency (odds ratio, 0.63; 95% confidence interval 0.42–0.94) deterred endoscopy. Surgical therapies were attempted equally (cyst removal, 7%; drainage procedure, 10%; resection procedure, 12%) except for surgical sphincteroplasty (4%; P<0.001). Surgical sphincteroplasty was the least effective therapy (46%; P<0.001) versus cyst removal (76% drainage [71%] and resection [73%]). CONCLUSIONS Although surgical therapies were performed less frequently than endoscopic therapies, they were more often reported to be effective. PMID:24717802

    Performing a surgical procedure during spaceflight will become more likely with longer duration missions in the near future. Minimal surgical capability has been present on previous missions as the definitive medical care time was short and the likelihood of surgical events too low to justify surgical hardware availability. Early demonstrations of surgical procedures in the weightlessness of parabolic flight indicated the need for careful logistical planning and restraint of surgical hardware. The consideration of human ergonomics also has more impact in weightlessness than in the conventionall-g environment. Three methods of surgical instrument restraint - a Minor Surgical Kit (MSK), a Surgical Restraint Scrub Suit (SRSS), and a Surgical Tray (ST) were evaluated in parabolic flight surgical procedures. The Minor Surgical Kit was easily stored, easily deployed, and demonstrated the best ability to facilitate a surgical procedure in weightlessness. Important factors in this surgical restraint system include excellent organization of supplies, ability to maintain sterility, accessibility while providing secure restraint, ability to dispose of sharp items and biological trash, and ergonomical efficiency.

    Recently, various video-assisted thoracoscopic surgical techniques have been reported with occasional success in treating hepatic hydrothorax (HH). In 2 patients with refractory HH, we applied a combination of four therapeutic modalities as a single procedure named as a "four-step approach": (1) pneumoperitoneum for localization of diaphragmatic defects, (2) thoracoscopic pleurodesis, (3) postoperative continuous positive airway pressure, and (4) drainage of ascites for abdominal decompression. The treatment was successful in both patients, without recurrence during the follow-up period of 24 and 3 months, respectively. PMID:26897210

  3. Stent-Grafts for Unruptured Abdominal Aortic Aneurysms: Current Status

    2006-06-15

    Aortic stent-grafts were introduced at the beginning of the 1990s as a less invasive method of dealing with aortic aneurysms in patients with poor cardiovascular reserve. The numbers of procedures performed worldwide has increased exponentially despite the current lack of any substantial evidence for long-term efficacy in comparison with the gold standard of open surgical grafting. This review summarizes the evolution of the abdominal aortic stent-graft, the techniques used for assessment and deployment, and the effect of the procedure on both the patient and the device. The recent publication of two national multicenter trials has confirmed that the endovascular technique confers a 2.5-fold reduction in 30-day mortality in comparison with open surgery. However, over 4 years of follow-up, there is a 3-fold increase in the risk of reintervention and the overall costs are 30% greater with endovascular repair. Although the improvement in aneurysm-related mortality persists in the mid-term, because of the initial reduction in perioperative mortality, the all-cause mortality rate at 4 years is actually no better than for open surgery. Longer-term data from the randomized trials are awaited as well as results from the latest trials utilizing state-of-the-art devices. Whilst the overall management of abdominal aortic aneurysms has undoubtedly benefited from the introduction of stent-grafts, open repair currently remains the gold standard treatment.

    OBJECT Thirty-day mortality is increasingly a reference metric regarding surgical outcomes. Recent data estimate a 30-day mortality rate of 1.4-2.7% after craniotomy for tumors in children. No detailed analysis of short-term mortality following a diagnostic neurosurgical procedure (e.g., resection or tissue biopsy) for tumor in the US pediatric population has been conducted. METHODS The Surveillance, Epidemiology and End Results (SEER) data sets identified patients ≤ 21 years who underwent a diagnostic neurosurgical procedure for primary intracranial tumor from 2004 to 2011. One- and two-month mortality was estimated. Standard statistical methods estimated associations between independent variables and mortality. RESULTS A total of 5533 patients met criteria for inclusion. Death occurred within the calendar month of surgery in 64 patients (1.16%) and by the conclusion of the calendar month following surgery in 95 patients (1.72%). Within the first calendar month, patients < 1 year of age (n = 318) had a risk of death of 5.66%, while those from 1 to 21 years (n = 5215) had a risk of 0.88% (p < 0.0001). By the end of the calendar month following surgery, patients < 1 year (n = 318) had a risk of death of 7.23%, while those from 1 to 21 years (n = 5215) had a risk of 1.38% (p < 0.0001). Children < 1 year at diagnosis were more likely to harbor a high-grade lesion than older children (OR 1.9, 95% CI 1.5-2.4). CONCLUSIONS In the SEER data sets, the risk of death within 30 days of a diagnostic neurosurgical procedure for a primary pediatric brain tumor is between 1.16% and 1.72%, consistent with contemporary data from European populations. The risk of mortality in infants is considerably higher, between 5.66% and 7.23%, and they harbor more aggressive lesions. PMID:26588456

    Purpose To report a case of Essure microinsert abdominal migration and literature review. Methods A 41-year-old woman was counseled to undergo Essure sterilization. The procedure was hampered by the presence of endometrial cavity adhesions, obscuring left tubal ostium. By using microscissors the adhesions were progressively lysed. Since the procedure had become very painful, the patient required general anesthesia. Once adhesion lysis was completed, the tubal ostium was well visible. Both devices were then easily introduced into the fallopian tubes. At the end of the procedure, five coils were visible on the right side and five coils on the left side, as recommended. Results The 3-month hysterosalpingogram follow-up suspected abdominal migration of the left device. Laparoscopy confirmed the device displacement in the left lower abdominal quadrant. Both fallopian tubes and the uterus appeared normal. No signs of perforation were detected. The device was embedded into the omentum, but it was easily removed. Bilateral tubal sterilization was performed by bipolar coagulation. Conclusion There are only 13 cases, including the present, of Essure abdominal migration in the literature. In most cases, abdominal displacement of the microinsert is asymptomatic and does not induce tissue damage. However, in some cases, it may cause a severe adverse event, requiring major surgery. Therefore, removal of the migrated device should be performed as soon as possible. Moreover, during presterilization counseling, the patient should also be correctly informed about the risk of this rare but relevant complication, as well as about the surgical interventions that could be required to solve it.

    Background Association between esophageal achalasia/ gastroesophageal reflux disease (GERD) and cholelithiasis is not clear. Epidemiological data are controversial due to different methodologies applied, the regional differences and the number of patients involved. Results of concomitant cholecistectomy associated to surgical treatment of both diseases regarding safety is poorly understood. Aim To analyze the prevalence of cholelithiasis in patients with esophageal achalasia and gastroesophageal reflux submitted to cardiomyotomy or fundoplication. Also, to evaluate the safety of concomitant cholecistectomy. Methods Retrospective analysis of 1410 patients operated from 2000 to 2013. They were divided into two groups: patients with GERD submitted to laparocopic hiatoplasty plus Nissen fundoplication and patients with esophageal achalasia to laparoscopic cardiomyotomy plus partial fundoplication. It was collected epidemiological data, specific diagnosis and subgroups, the presence or absence of gallstones, surgical procedure, operative and clinical complications and mortality. All groups/subgroups were compared. Results From 1,229 patients with GERD or esophageal achalasia, submitted to laparoscopic cardiomyotomy or fundoplication, 138 (11.43%) had cholelitiasis, occurring more in females (2.38:1) with mean age of 50,27 years old. In 604 patients with GERD, 79 (13,08%) had cholelitiasis. Lower prevalence occurred in Barrett's esophagus patients 7/105 (6.67%) (p=0.037). In 625 with esophageal achalasia, 59 (9.44%) had cholelitiasis, with no difference between chagasic and idiopathic forms (p=0.677). Complications of patients with or without cholecystectomy were similar in fundoplication and cardiomyotomy (p=0.78 and p=1.00).There was no mortality or complications related to cholecystectomy in this series. Conclusions Prevalence of cholelithiasis was higher in patients submitted to fundoplication (GERD). Patients with chagasic or idiopatic forms of achalasia had the

  10. Surgical strategy for low rectal cancers.

    PubMed

    Dumont, F; Mariani, A; Elias, D; Goéré, D

    2015-02-01

    The two goals of surgery for lower rectal cancer surgery are to obtain clear "curative" margins and to limit post-surgical functional disorders. The question of whether or not to preserve the anal sphincter lies at the center of the therapeutic choice. Histologically, tumor-free distal and circumferential margins of>1mm allow a favorable oncologic outcome. Whether such margins can be obtained depends of TNM staging, tumor location, response to chemoradiotherapy and type of surgical procedure. The technique of intersphincteric resection relies on these narrow margins to spare the sphincter. This procedure provides satisfactory oncologic outcome with a rate of circumferential margin involvement ranging from 5% to 11%, while good continence is maintained in half of the patients. The extralevator abdominoperineal resection provides good oncologic results, however this procedure requires a permanent colostomy. A permanent colostomy alters several domains of quality of life when located at the classical abdominal site but not when brought out at the perineal site as a perineal colostomy. PMID:25455959

    The contribution of abdominal aortic aneurysm (AAA) disease to human morbidity and mortality has increased in the aging, industrialized world. In response, extraordinary efforts have been launched to determine the molecular and pathophysiological characteristics of the diseased aorta. This work aims to develop novel diagnostic and therapeutic strategies to limit AAA expansion and, ultimately, rupture. Contributions from multiple research groups have uncovered a complex transcriptional and post-transcriptional regulatory milieu, which is believed to be essential for maintaining aortic vascular homeostasis. Recently, novel small noncoding RNAs, called microRNAs, have been identified as important transcriptional and post-transcriptional inhibitors of gene expression. MicroRNAs are thought to "fine tune" the translational output of their target messenger RNAs (mRNAs) by promoting mRNA degradation or inhibiting translation. With the discovery that microRNAs act as powerful regulators in the context of a wide variety of diseases, it is only logical that microRNAs be thoroughly explored as potential therapeutic entities. This current review summarizes interesting findings regarding the intriguing roles and benefits of microRNA expression modulation during AAA initiation and propagation. These studies utilize disease-relevant murine models, as well as human tissue from patients undergoing surgical aortic aneurysm repair. Furthermore, we critically examine future therapeutic strategies with regard to their clinical and translational feasibility. PMID:23852016

    A 79-year-old woman presented to a private medical practice 2 years previously for an elective ultrasound screening scan. This imaging provided the evidence for a diagnosis of an abdominal aortic aneurysm (AAA) to be made. Despite having a number of recognised risk factors for an AAA, her general practitioner at the time did not follow the guidance set out by the private medical professional, that is, to refer the patient to a vascular specialist to be entered into a surveillance programme and surgically evaluated. The patient became symptomatic with her AAA, was admitted to hospital and found to have a tender, symptomatic, 6 cm leaking AAA. She consented for an emergency open AAA repair within a few hours of being admitted to hospital, despite the 50% perioperative mortality risk. The patient spent 4 days in intensive care where she recovered well. She was discharged after a 12 day hospital stay but unfortunately passed away shortly after her discharge from a previously undiagnosed gastric cancer. PMID:25398912

    Aneurysm is defined as a localized and permanent dilatation with an increase in normal diameter by more than 50%. It is more common in males and can affect up to 8% of elderly men. Smoking is the greatest risk factor for abdominal aortic aneurysm (AAA) and other risk factors include hypertension, hyperlipidemia, family history of aneurysms, inflammatory vasculitis, and trauma. Endovascular Aneurysm Repair [EVAR] is a common procedure performed for AAA, because of its minimal invasiveness as compared with open surgical repair. Patients undergoing EVAR have a greater incidence of major co-morbidities and should undergo comprehensive preoperative assessment and optimization within the multidisciplinary settings. In majority of cases, EVAR is extremely well-tolerated. The aim of this article is to outline the Anesthetic considerations related to EVAR. PMID:26750684

    In Japan, peritoneal dialysis (PD) catheter insertion has been performed by both nephrologists and surgeons. However, nephrologists have fewer opportunities to train in the insertion procedure. We therefore used a PD access simulator to provide training in this operative technique for nephrologists. A PD access simulator developed by Terumo Medical Corporation was used for the training. The simulator uses a mannequin made of acrylic resin. The abdominal wall of a pig is attached to the abdominal area, and a plastic bag represents the abdominal cavity. The simulator enables the surgical procedure to be performed from skin incision to PD catheter insertion. Between October 2011 and December 2013, 3 supervising doctors used the simulator to guide 17 nephrologists with no experience through a PD catheter insertion. One-on-one training was provided in a single 2- or 3-hour session. In a questionnaire survey after the training, trainees gave high marks to the handling of surgical instruments, the environment of the operating room, and the surgical guidance during training. However, the supervising doctors required the ability to respond flexibly, because trainees had individual differences in skills. The PD access simulator might be useful for providing guided training in operative technique for PD catheter insertion. PMID:26714382

  15. Acute Abdominal Pain in Children.

    Acute abdominal pain accounts for approximately 9% of childhood primary care office visits. Symptoms and signs that increase the likelihood of a surgical cause for pain include fever, bilious vomiting, bloody diarrhea, absent bowel sounds, voluntary guarding, rigidity, and rebound tenderness. The age of the child can help focus the differential diagnosis. In infants and toddlers, clinicians should consider congenital anomalies and other causes, including malrotation, hernias, Meckel diverticulum, or intussusception. In school-aged children, constipation and infectious causes of pain, such as gastroenteritis, colitis, respiratory infections, and urinary tract infections, are more common. In female adolescents, clinicians should consider pelvic inflammatory disease, pregnancy, ruptured ovarian cysts, or ovarian torsion. Initial laboratory tests include complete blood count, erythrocyte sedimentation rate or C-reactive protein, urinalysis, and a pregnancy test. Abdominal radiography can be used to diagnose constipation or obstruction. Ultrasonography is the initial choice in children for the diagnosis of cholecystitis, pancreatitis, ovarian cyst, ovarian or testicular torsion, pelvic inflammatory disease, pregnancy-related pathology, and appendicitis. Appendicitis is the most common cause of acute abdominal pain requiring surgery, with a peak incidence during adolescence. When the appendix is not clearly visible on ultrasonography, computed tomography or magnetic resonance imaging can be used to confirm the diagnosis. PMID:27175718

    Intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are rare but potentially morbid diagnoses. Clinical index of suspicion for these disorders should be raised following massive resuscitation, abdominal wall reconstruction/injury, and in those with space-occupying disorders in the abdomen. Gold standard for diagnosis involves measurement of bladder pressure, with a pressure greater than 12 mm Hg being consistent with IAH and greater than 25 mm Hg being consistent with ACS. Decompressive laparotomy is definitive therapy but paracentesis can be equally therapeutic in properly selected patients. Left untreated, ACS can lead to multisystem organ failure and death.

    Introduction Here, we report the surgical excision of the urachal remnant using the abdominal wall-lift laparoscopy with a camera port in the umbilicus, combined with a small Pfannenstiel incision to optimally treat the bladder apex. Presentation of case A 21-year-old woman presented with periumbilical discharge and pain on urination. Contrast enhanced CT and MRI showed an abscess in the umbilical region that was connected to the bladder via a long tube-like structure. It was diagnosed as an infected urachal sinus. Partial excision of the umbilical fossa followed by dissection of the urachal remnant was easily performed using the abdominal wall-lift laparoscopy from the umbilicus down to the bladder without pneumoperitoneum or additional trocar placement. A Pfannenstiel incision was made above the pubis to get access to the junction between the urachal remnant and the bladder. Under direct vision, we succeeded in accurately dividing the remnant tract, and we adequately closed the bladder opening with absorbable sutures. This method has the advantage of easily closing peritoneal defects after excision of the urachal remnant with direct sutures under a laparoscopic view from the umbilicus. Cosmetic satisfaction was obtained postoperatively. Discussion and conclusion Urachal sinus excision using the abdominal wall-lift laparoscopy seems to surpass the previously reported methods in term of safety, cosmetics, and adequacy of surgical procedures.

    Lateral abdominal wall hernias may occur after a variety of procedures, including anterior spine exposure, urologic procedures, ostomy closures, or after trauma. Anatomically, these hernias are challenging and require a complete understanding of abdominal wall, interparietal and retroperitoneal, anatomy for successful repair. Mesh placement requires extensive dissection of often unfamiliar planes, and its fixation is difficult. We report our experience with open mesh repair of lateral abdominal wall hernias. A retrospective review of a prospectively maintained database was performed to identify patients with a classification of lateral abdominal wall hernia who underwent an open repair. A total of 61 patients underwent open lateral hernia repairs. Mean patient age was 58 years (range 25-78), with a mean body mass index of 32 kg/m(2) (range 19.0-59.1). According to the European Hernia Society classification, defects were located subcostal (L1, 14 patients), flank (L2, 33 patients), iliac (L3, 11 patients), and lumber (L4, 3 patients). Mean defect size was 78.6 cm(2), with a mean greatest single dimension of 9.2 cm (range 2-25 cm). Retromuscular or interparietal repair was performed in 50.8 per cent, preperitoneal in 41.0 per cent, intraperitoneal in 6.6 per cent, and onlay in 1.6 per cent. The rate of surgical site occurrence was 49.2 per cent, primarily seroma and surgical site infection rate was 13.1 per cent. With a mean follow-up of 15.4 months, seven patients (11.5%) have documented recurrence. Synthetic mesh reconstruction of lateral wall hernias is challenging. Our experience demonstrates the safety and success of repair using synthetic mesh primarily in the retromuscular, interparietal, or preperitoneal planes. PMID:27457859

    The abdominal compartment is separated from the thoracic compartment by the diaphragm. Under normal circumstances, a large portion of the venous return crosses the splanchnic and nonsplanchnic abdominal regions before entering the thorax and the right side of the heart. Mechanical ventilation may affect abdominal venous return independent of its interactions at the thoracic level. Changes in pressure in the intra-abdominal compartment may have important implications for organ function within the thorax, particularly if there is a sustained rise in intra-abdominal pressure. It is important to understand the consequences of abdominal pressure changes on respiratory and circulatory physiology. This article elucidates important abdominal-respiratory-circulatory interactions and their clinical effects. PMID:27016167

    Introduction Urinary incontinence negatively affects the quality of life. Various methods are used in the treatment of stress incontinence. Burch colposuspension (BC) is the classical treatment of urinary incontinence. Aim To compare the long-term satisfaction in patients receiving BC with or without concomitant total abdominal hysterectomy. Materials and Methods One hundred and twenty patients with stress incontinence underwent burch colposuspension with or without concomitant total abdominal hysterectomy. Ninety-three (77.5%) patients were interviewed by telephone. Of these, 91(75, 8%) patients agreed to participate in the study. The patients were divided into two groups according to the type of the surgical procedure. Group 1(N=48, 52.7%) had received burch colposuspension with concomitant total abdominal hysterectomy. Group 2 (N=43, 47.3%) had received burch colposuspension without concomitant total abdominal hysterectomy. Results In Group 1, 41 patients (85%) were satisfied with the surgery and did not complain of urinary incontinence (p<0.05). In Group 2, 37 (86%) patients were satisfied with the surgery (p<0.05). Conclusion There were no difference in patient satisfaction between hysterectomy and BC and only BC to treat incontinence. PMID:26816948

    2013-01-01

    Introduction Hydatidosis is endemic in the Mediterranean region including morrocco, the Middle and Far East, Australia, New Zealand, and South America—all areas where animal husbandry is common. Rupture into the abdominal cavity is a rare but serious complication of hydatid disease. The cysts may be ruptured after a trauma, or spontaneously as a result of increased intracystic pressure. Rupture of the hydatid cyst requires emergency surgical intervention. Methods Fourteen patients received surgical treatment for intraperitoneal rupture of the cysts over a period of 5 years. Age, gender, time to surgery from the onset of the symptoms, laboratory findings, diagnostic procedures, surgical treatment modalities, in-hospital stay, morbidity, mortality and recurrence were evaluated retrospectively. Results Eight of the patients were men and six were women. All of the patients had signs of peritoneal irritation. One patient (7,14%) had a history of blunt abdominal trauma. Ultrasonography scans revealed intra-abdominal fluid in all cases, intraperitoneal multiple cysts in 11 cases and heterogeneous cavity or cystic structures in the liver in 12 cases. Computed tomography showed multiple cystic lesions in the liver and peritoneum with intra-abdominal free fluid. The ruptured cysts were located in the right lobe of the liver in seven patients, in the left lobe in six patients and in both lobes in one patients. Procedures to fill the cystic cavities were applied after removal of the intraperitoneal fluid. Partial pericystectomy and drainage was the most frequent surgical procedure. No patients died in the early postoperative period. A total of seven morbidities developed in six patients (35.3%). Median hospital stay was 08 days and median follow-up was 12 months. Intra-abdominal recurrence occurred in one case (7.7%). Conclusions Rupture of hydatid cysts into the peritoneal cavity, although rare, presents a challenge for surgeons. This pathology should be included in the

    Necrotising enterocolitis (NEC) is a neonatal surgical emergency. At its early stages, the management of NEC is largely medical using broad-spectrum antibiotics, gut rest and total parental nutrition. The only absolute indication for surgery is an intra-abdominal perforation. There are several relative indications for surgery based on clinical, biochemical and radiological parameters. Once the decision to intervene is made, several approaches may be taken. Peritoneal lavage can be used as a salvage procedure or definitive management in some cases. The most common approach taken is bowel resection with enterostomy formation. There is a role for primary anastomosis of bowel in limited NEC. In severe, multi-focal NEC a high diverting jejunostomy or "clip and drop technique" can be used. Laparoscopy has a limited role and is not widespread. The surgical complications of NEC include stoma related morbidity, anastomotic leak/stricture and short-bowel syndrome. Long-term data on neurodevelopmental outcomes is sparse but the present literature is suggestive of a negative impact in cases of surgically managed NEC. PMID:27032753

    BACKGROUND: Incidence of postoperative pulmonary complications (PPC) in patients undergoing non-cardiothoracic surgery remains high and the occurrence of these complications has enormous implications for the patient and the health care system. AIM: The aim of the study was to identify risk factors for PPC in patients undergoing abdominal surgical procedures. MATERIALS AND METHODS: A prospective cohort study in abdominal surgical patients, admitted to the emergency and surgical ward of the UHC of Tirana, Albania, was conducted during the period: March 2014-March 2015. We collected data on the occurrence of a symptomatic and clinically significant PPC using clinical, laboratory, and radiology data. We evaluated the relations between PPCs and various pre-operative or intra-operative factors to identify risk factors. RESULTS: A total of 450 postoperative patients admitted to the surgical emergency and surgical ward were studied. The mean age were 59.85 ±13.64 years with 59.3% being male. Incidence of PPC was 27.3% (123 patients) and hospital length of stay was 4.93 ± 4.65 days. Length of stay was substantially prolonged for those patients who developed PPC (7.48 ± 2.89 days versus 3.97± 4.83 days, p < 0.0001. PPC were identified as risk factors for mortality, OR: 21.84; 95% CI: 11.66-40.89; P < 0.0001. The multivariate regression analysis identified as being independently associated with an increased risk of PPC: age ≥ 65 years (OR 11.41; 95% CI: 4.84-26.91, p < 0.0001), duration of operation ≥ 2.5 hours (OR 8.38; 95% CI: 1.52-46.03, p = 0.01, history of previous pulmonary diseases (OR 11.12; 95% CI: 3.28-37.65, P = 0.0001) and ASA > 2 (OR 6.37; 95% CI: 1.54-26.36, P = 0.01). CONCLUSION: We must do some efforts in reducing postoperative pulmonary complications, firstly to identify which patients are at increased risk, and then following more closely high-risk patients because those patients are most likely to benefit.

    Unsafe abortion is one of the causes of maternal mortality and morbidity in developing countries. The complications mostly results following unsafe abortion procedure done by unskilled provider with or without minimal medical knowledge in rural part of developing countries. These complications can endanger the life of mother if proper medical or surgical interventions are not offered in time. A majority of these complications remains confidential. The uterine perforation is one of the serious but preventable complications of surgical abortion. A 21-year-old woman G4P2L2A1, presented in the emergency ward with complaints of lower abdominal pain for four days after attempting twice surgical termination of pregnancy at 19 weeks of gestation for an unwanted pregnancy. Transabdominal sonography and MRI revealed uterine rent with pelvic extrusion of fetal head. Emergency laparotomy with removal of fetal head and uterine rent repair was done. This case illustrates the importance of maintaining a high index of suspicion by the gynaecologist for uterine perforation in patient presenting with abdominal pain a few days after undergoing surgical abortion, also shows the complementary role of sonography and MRI in evaluation of the similar patient and this case also highlights the rampant illegal unsafe abortion procedure in rural India despite of legalization of abortion act.

    With advances in abdominal surgery and the management of major trauma, complex abdominal wall defects have become the new surgical disease, and the need for abdominal wall reconstruction has increased dramatically. Subsequently, how to reconstruct these large defects has become a new surgical question. While most surgeons use native abdominal wall whenever possible, evidence suggests that synthetic or biologic mesh needs to be added to large ventral hernia repairs. One particular group of patients who exemplify "complex" are those with contaminated wounds, enterocutaneous fistulas, enteroatmospheric fistulas, and/or stoma(s), where synthetic mesh is to be avoided if at all possible. Most recently, biologic mesh has become the new standard in high-risk patients with contaminated and dirty-infected wounds. While biologic mesh is the most common tissue engineered used in this field of surgery, level I evidence is needed on its indication and long-term outcomes. Various techniques for reconstructing the abdominal wall have been described, however the long-term outcomes for most of these studies, are rarely reported. In this article, I outline current practical approaches to perioperative management and definitive abdominal reconstruction in patients with complex abdominal wall defects, with or without fistulas, as well as those who have lost abdominal domain.

    Recent technological advances in the diagnosis and therapy of abdominal aortic aneurysm and renovascular disease are continuing to bring about changes in the way patients suffering from these conditions are treated. The prevalence of both these conditions is increasing. This is due to greater life-expectancy in patients with arteriosclerosis, a pathogenetic factor underlying both conditions. The application of diagnostic imaging techniques to non-vascular conditions has led to the early diagnosis of abdominal aortic aneurysm. Clinical suspicion of reno-vascular disease can be confirmed easily using high-resolution diagnostic imaging modalities such as CT angiography and magnetic resonance angiography. Endovascular intervention is successfully replacing conventional surgical repair techniques, with the result that it may be possible to improve outcome in both conditions using effective and minimally invasive approaches. Future technological developments will enable these endovascular techniques to be applied in the large majority of patients with abdominal aortic aneurysm or renovascular disease. PMID:17580053

    Mesh materials have undergone a considerable evolution over the last several decades. There has been enhancement of biomechanical properties, improvement in manufacturing processes, and development of antiadhesive laminate synthetic meshes. The evolution of bioprosthetic mesh materials has markedly changed our indications and methods for complex abdominal wall reconstruction. The authors review the optimal properties of bioprosthetic mesh materials, their evolution over time, and their indications for use. The techniques to optimize outcomes are described using bioprosthetic mesh for complex abdominal wall reconstruction. Bioprosthetic mesh materials clearly have certain advantages over other implantable mesh materials in select indications. Appropriate patient selection and surgical technique are critical to the successful use of bioprosthetic materials for abdominal wall repair. PMID:23372454

    Introduction Vacuum-assisted closure (VAC) is useful for treating complex wounds because it promotes granulation. In the present report, a successful case of VAC used for an open abdominal wound with enterocutaneous fistulae after multiple intestinal perforations during chemotherapy is described. Presentation of case A 73-year-old man was admitted to our hospital with severe abdominal pain. He underwent surgical resection for ascending colon cancer 4 years ago and was administered chemotherapy with bevacizumab for recurrence. Physical examination and computed tomography revealed perforation of the intestine, and an emergency operation was performed. Following this procedure, other intestinal perforations occurred, resulting in an open abdominal wound at postoperative day (POD) 10. To isolate enteric contents and promote granulation, VAC was applied to the abdominal wound with enterocutaneous fistulae. Oral intake started at POD 21 and the wound size became smaller. Further, an ostomy bag was directly attached to the most oral perforation site. The patient recovered from life-threatening events without severe infection and was transferred to another hospital close to his home at POD 180. Discussion Gastrointestinal perforation is known to be one of the fatal adverse events of bevacizumab. In this case four gastrointestinal perforations were observed. Isolation of enteric contents is important to heal the wound and VAC is an effective therapy for the management of open abdominal wounds even with enterocutaneous fistulae. Conclusion Innovative VAC use for the management of open abdominal wounds can improve the nutritional status and overall wound healing of the patient. PMID:26599504

    BACKGROUND Localised oesophageal cancer can be curatively treated with surgery (oesophagectomy) but the procedure is complex with a risk of complications, negative effects on quality of life and a recovery period of 6-9 months. Minimal-access surgery may accelerate recovery. OBJECTIVES The ROMIO (Randomised Oesophagectomy: Minimally Invasive or Open) study aimed to establish the feasibility of, and methodology for, a definitive trial comparing minimally invasive and open surgery for oesophagectomy. Objectives were to quantify the number of eligible patients in a pilot trial; develop surgical manuals as the basis for quality assurance; standardise pathological processing; establish a method to blind patients to their allocation in the first week post surgery; identify measures of postsurgical outcome of importance to patients and clinicians; and establish the main cost differences between the surgical approaches. DESIGN Pilot parallel three-arm randomised controlled trial nested within feasibility work. SETTING Two UK NHS departments of upper gastrointestinal surgery. PARTICIPANTS Patients aged ≥ 18 years with histopathological evidence of oesophageal or oesophagogastric junctional adenocarcinoma, squamous cell cancer or high-grade dysplasia, referred for oesophagectomy or oesophagectomy following neoadjuvant chemo(radio)therapy. INTERVENTIONS Oesophagectomy, with patients randomised to open surgery, a hybrid open chest and minimally invasive abdomen or totally minimally invasive access. MAIN OUTCOME MEASURE The primary outcome measure for the pilot trial was the number of patients recruited per month, with the main trial considered feasible if at least 2.5 patients per month were recruited. RESULTS During 21 months of recruitment, 263 patients were assessed for eligibility; of these, 135 (51%) were found to be eligible and 104 (77%) agreed to participate, an average of five patients per month. In total, 41 patients were allocated to open surgery, 43 to the

    AIM: To investigate the role of laparoscopy in diagnosis and treatment of intra abdominal infections. METHODS: A systematic review of the literature was performed including studies where intra abdominal infections were treated laparoscopically. RESULTS: Early laparoscopic approaches have become the standard surgical technique for treating acute cholecystitis. The laparoscopic appendectomy has been demonstrated to be superior to open surgery in acute appendicitis. In the event of diverticulitis, laparoscopic resections have proven to be safe and effective procedures for experienced laparoscopic surgeons and may be performed without adversely affecting morbidity and mortality rates. However laparoscopic resection has not been accepted by the medical community as the primary treatment of choice. In high-risk patients, laparoscopic approach may be used for exploration or peritoneal lavage and drainage. The successful laparoscopic repair of perforated peptic ulcers for experienced surgeons, is demonstrated to be safe and effective. Regarding small bowel perforations, comparative studies contrasting open and laparoscopic surgeries have not yet been conducted. Successful laparoscopic resections addressing iatrogenic colonic perforation have been reported despite a lack of literature-based evidence supporting such procedures. In post-operative infections, laparoscopic approaches may be useful in preventing diagnostic delay and controlling the source. CONCLUSION: Laparoscopy has a good diagnostic accuracy and enables to better identify the causative pathology; laparoscopy may be recommended for the treatment of many intra-abdominal infections.

    The optimal treatment strategy for an incomplete nasolacrimal duct obstruction (INDO) is still being debated. The aim of this study is to evaluate the treatment results of combined lacrimal passage probing and tobramycin/dexamethasone ophthalmic ointment infiltration (PIO, Probing and Injection) for INDO.In this retrospective, noncomparative case series, 397 consecutive adult patients with INDO treated at Shanghai Eye, Ear, Nose and Throat Hospital were enrolled. Records of the patients were reviewed. With the help of a modified 23-gauge lacrimal cannula, the PIO surgery was performed for the INDO-identified patients. The main outcome measures were resolution of tearing and complications. The relationship between successful outcome and clinical characteristics was analyzed.The surgery was performed successfully in all of the enrolled cases. No intraoperative complications were found in the procedure. The average follow-up time was 7.9 months. Three hundred patients (75.6%) experienced complete resolution of their symptoms after the surgery. Ninety-seven patients (24.4%) showed a partial improvement (1.8%), no improvement (18.4%), or a worsening of symptoms (4.3%). Of the 97 surgical-failure patients, 90 required silicone intubation or external dacryocystorhinostomy, and 94% were finally resolved. The most common postoperative complications were mild nasal bleeding in 41 patients, drug residues in 12 patients (6 developed the complete obstruction), and a slit punctum in 8 patients. Multivariate logistic regression analysis revealed that unilateral eye onset, not having a discharge at baseline, and not having postoperative drug residues were significant factors determining successful outcome.The PIO surgery is an effective, safe, timesaving, easy-to-perform, and minimally invasive technique for treating INDO.

    Objectives: Incisional hernia (IH) remains a common, highly morbid, and costly complication. Modest progress has been realized in surgical technique and mesh technology; however, few advances have been achieved toward understanding risk and prevention. In light of the increasing emphasis on prevention in today's health care environment and the billions in costs for surgically treated IH, greater focus on predictive risk models is needed. Methods: All patients undergoing gastrointestinal or gynecologic procedures from January 1, 2005 to June 1, 2013, within the University of Pennsylvania Health System were identified. Comorbidities and operative characteristics were assessed. The primary outcome was surgically treated IH after index procedures. Patients with prior hernia, less than 1-year follow-up, or emergency surgical procedures were excluded. Cox hazard regression modeling with bootstrapped validation, risk factor stratification, and assessment of model performance were conducted. Results: A total of 12,373 patients with a 3.5% incidence of surgically treated IH (follow-up 32.2 ± 26.6 months) were identified. The cost of surgical treatment of IH and management of associated complications exceeded $17.5 million. Notable independent risk factors for IH were ostomy reversal (HR = 2.76), recent chemotherapy (HR = 2.04), bariatric surgery (HR = 1.78), smoking history (HR = 1.74), liver disease (HR = 1.60), and obesity (HR = 1.96). High-risk patients (20.6%) developed IH compared with 0.5% of low-risk patients (C-statistic = 0.78). Conclusions: This study demonstrates an internally validated preoperative risk model of surgically treated IH after 12,000 elective, intra-abdominal procedures to provide more individualized risk counseling and to better inform evidence-based algorithms for the role of prophylactic mesh.

    Laparoscopy is an established method for the treatment of numerous surgical conditions. Natural orifice transluminal endoscopic surgery (NOTES) is a novel surgical technique that uses the natural orifices of the human body as entrances to the abdominal cavity. An alternative concept of minimally invasive approach to the abdominal cavity is to insert all the laparoscopic instruments through ports using a single small incision on the abdominal wall. A suggested name for this technique is laparoendoscopic single-site surgery (LESS). Considering the technical difficulties in NOTES and LESS and the progress in informatics and robotics, the use of robots seems ideal. The aim of this study is to investigate if there is at present, a realistic possibility of using miniature robots in NOTES or LESS in daily clinical practice. An up-to-date review on in vivo surgical miniature robots is made. A Web-based research of the English literature up to March 2013 using PubMed, Scopus, and Google Scholar as search engines was performed. The development of in vivo miniature robots for use in NOTES or LESS is a reality with great advancements, potential advantages, and possible application in minimally invasive surgery in the future. However, true totally NOTES or LESS procedures on humans using miniature robots either solely or as assistance, remain a dream at present. PMID:24828382

    Abdominal pregnancy is a rare entity, which has been classified as primary or secondary by Studiford criteria. A retrospective study, between January 1989 and December 1994, realized at Instituto Nacional de Perinatología, found 35,080 pregnancies, from which 149 happened to be ectopic, and 6 of them were abdominal. All patients belonged to a low income society class, age between 24 and 35 years, and average of gestations in 2.6. Gestational age varied from 15 weeks to 32.2 weeks having only one delivery at term with satisfactory postnatal evolution. One patient had a recurrent abdominal pregnancy, with genital Tb as a conditional factor. Time of hospitalization varied from 4 to 5 days, and no further patient complications were reported. Fetal loss was estimated in 83.4%. Abdominal pregnancy is often the sequence of a tubarian ectopic pregnancy an when present, it has a very high maternal mortality reported in world literature, not found in this study. The stated frequency of abdominal pregnancy is from 1 of each 3372, up to 1 in every 10,200 deliveries, reporting in the study 1 abdominal pregnancy in 5846 deliveries. The study had two characteristic entities one, the recurrence and two, the delivery at term of one newborn. Abdominal pregnancy accounts for 4% of all ectopic pregnancies. Clinical findings in abdominal pregnancies are pain, transvaginal bleeding and amenorrea, being the cardinal signs of ectopic pregnancy. PMID:9737070

    Background and Objectives: Keyless abdominal rope-lifting surgery is a novel, gasless, single-incision laparoscopic surgical technique. In this study we aimed to compare the postoperative pain from keyless abdominal rope-lifting surgery with carbon dioxide laparoscopy performed for benign ovarian cysts. Methods: During a 20-month period, 77 women underwent surgery for a benign ovarian cyst. Keyless abdominal rope-lifting surgery and conventional carbon dioxide laparoscopy techniques were used for the operations in 32 women and 45 women, respectively. The 2 operative techniques were compared with regard to demographic characteristics; preoperative, intraoperative, and postoperative data including early postoperative pain scores; and frequency of shoulder pain and analgesic requirements. Results: Data regarding demographic characteristics, preoperative findings, cyst diameters and rupture rates, intra-abdominal adhesions, intraoperative blood loss, and postoperative hospital stay did not differ between groups (P > .05). However, the mean operative and abdominal access times were significantly longer in the keyless abdominal rope-lifting surgery group (P < .05). Visual analog scale pain scores at initially and at the second, fourth, and 24th hours of the postoperative period were significantly lower in the keyless abdominal rope-lifting surgery group (P < .05). Similarly, keyless abdominal rope-lifting surgery caused significantly less shoulder pain and additional analgesic use (P < .05). Conclusion: Keyless abdominal rope-lifting surgery seems to cause less pain in the management of benign ovarian cysts in comparison with conventional carbon dioxide laparoscopy. PMID:25848177

    A project was undertaken to improve robotic surgical tools for telerobotic minimally invasive surgery. The major objectives were to reduce the size of the tools to permit new surgical procedures in confined spaces such as the heart and to improve control of surgical tools by locating positional sensors and actuators at the end effector rather than external to the patient as is currently the state of the technology. A new compact end-effector with wrist-like flexibility was designed. Positional sensors based on MEMS microfabrication techniques were designed.

    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

    Intra-abdominal abscess is seldom adequately treated by systemic antibiotics alone and often requires surgical or computed tomography-guided drainage for resolution. Abscess penetration of six currently used antibiotics was examined in a murine intra-abdominal abscess model. Ampicillin/sulbactam, cefmetazole, clindamycin, and trospectomycin penetrated intra-abdominal abscesses to a greater degree than cefoxitin and ceftriaxone. Abscess pus antibiotic levels were not significantly higher after multiple doses than after a single dose. Pus antibiotic levels below the MIC90 for Bacteroides and E. coli within intra-abdominal abscess were observed for most antibiotics with the doses used in this study. Selection of antibiotics with a greater ability to penetrate abscess may be important in optimally treating patients with abdominal infection. PMID:7762902

    Acquired immune deficiency syndrome (AIDS) is a recently recognized entity characterized by a deficiency in cell mediated immune response. The syndrome is manifested by the development of otherwise rare malignant neoplasms and severe life-threatening opportunistic infections. Case histories of five AIDS patients evaluated for abdominal pain are presented to demonstrate the unusual spectrum of intra-abdominal pathology that may be encountered in the AIDS patient. As the number of patients with AIDS continues to escalate, surgical evaluation and intervention will be required more frequently. An understanding of this syndrome and its complications is mandatory for the surgeon to adequately evaluate AIDS patients with abdominal pain. PMID:6322708

    Background: To examine the on-call emergency workload of a general surgical team at a tertiary care teaching hospital to guide planning and provision of better surgical services. Patients and Methods: During six months period from August to January 2007; all emergency calls attended by general surgical team of Surgical Unit II in Accident and Emergency department (A and E) and in other units of Civil, Hospital Karachi, Pakistan were prospectively recorded. Data recorded includes timing of call, diagnosis, operation performed and outcome apart from demography. Results: Total 456 patients (326 males and 130 females) were attended by on-call general surgery team during 30 emergency days. Most of the calls, 191 (41.9%) were received from 8 am to 5 pm. 224 (49.1%) calls were of abdominal pain, with acute appendicitis being the most common specific pathology in 41 (9.0%) patients. Total 73 (16.0%) calls were received for trauma. Total 131 (28.7%) patients were admitted in the surgical unit for urgent operation or observation while 212 (46.5%) patients were discharged from A and E. 92 (20.1%) patients were referred to other units with medical referral accounts for 45 (9.8%) patients. Total 104 (22.8%) emergency surgeries were done and the most common procedure performed was appendicectomy in 34 (32.7%) patients. Conclusion: Major workload of on-call surgical emergency team is dealing with the acute conditions of abdomen. However, significant proportion of patients are suffering from other conditions including trauma that require a holistic approach to care and a wide range of skills and experience. These results have important implications in future healthcare planning and for the better training of general surgical residents. PMID:19561950

    This paper considers two new elevator and dental forceps techniques for the atraumatic removal of teeth to avoid a surgical procedure where possible. The techniques described should be applicable in relatively well defined but commonly occurring situations. The two techniques involve the unconventional use of conventional dental extraction forceps, with the aim of facilitating removal of the retained roots of certain teeth: the first for incisors, canines and premolars and the second for lower first molars. The term 'surgical forceps technique's is tentatively put forward as a description of these hybrid procedures. PMID:11819949

    In the current study, a case of recurrent desmoplastic small round cell tumor (DSRCT) is presented, which was successfully treated by repetitive debulking surgery. In May 2010, a 39-year-old male, with a history of surgical resection of intra-abdominal DSRCT, visited the Ibaraki Medical Center, Tokyo Medical University Hospital (Ami, Japan) with severe lower abdominal discomfort. Abdominal computed tomography revealed a large tumor in the pouch of Douglas with a small number of nodules in the abdominal cavity. The recurrent DSRCT was diagnosed and removed via lower anterior resection; however, complete resection was impossible due to multiple peritoneal metastases. One year later, the patient developed pain in the right groin due to the growth of metastasized tumor cells in the groin lymph nodes. The affected lymph nodes were removed utilizing an extra-peritoneal approach. At the time of writing, the patient continues to survive without any symptoms 60 months since the initial surgery. In conclusion, surgical debulking is a significant procedure for relieving patient symptoms as well as improving the survival time of patients with metastatic and recurrent DSRCT. PMID:24765157

  10. A focus on intra-abdominal infections

    PubMed Central

    2010-01-01

    Complicated intra-abdominal infections are an important cause of morbidity and are frequently associated with poor prognosis, particularly in higher risk patients. Well defined evidence-based recommendations for intra-abdominal infections treatment are partially lacking because of the limited number of randomized-controlled trials. Factors consistently associated with poor outcomes in patients with intra-abdominal infections include increased illness severity, failed source control, inadequate empiric antimicrobial therapy and healthcare-acquired infection. Early prognostic evaluation of complicated intra-abdominal infections is important to select high-risk patients for more aggressive therapeutic procedures. The cornerstones in the management of complicated intra-abdominal infections are both source control and antibiotic therapy. The timing and the adequacy of source control are the most important issues in the management of intra-abdominal infections, because inadequate and late control of septic source may have a negative effect on the outcomes. Recent advances in interventional and more aggressive techniques could significantly decrease the morbidity and mortality of physiologically severe complicated intra-abdominal infections, even if these are still being debated and are yet not validated by limited prospective trials. Empiric antimicrobial therapy is nevertheless important in the overall management of intra-abdominal infections. Inappropriate antibiotic therapy may result in poor patient outcomes and in the appearance of bacterial resistance. Antimicrobial management is generally standardised and many regimens, either with monotherapy or combination therapy, have proven their efficacy. Routine coverage especially against Enterococci and candida spp is not always recommended, but can be useful in particular clinical conditions. A de escalation approach may be recommended in patients with specific risk factors for multidrug resistant infections such as

    Breast reconstruction using free tissue transfer is an increasingly utilised oncoplastic procedure. The aim was to review all bilateral breast reconstructions using abdominal free flaps by a single surgeon over an 11-year period (2003–2014). A retrospective review was performed on all patients who underwent bilateral breast reconstruction using abdominal free flaps between 2003 and 2014 by the senior author (DAM). Data analysed included patient demographics, indication for reconstruction, surgical details, and complications. Fifty-five female patients (mean 48.6 years [24–71 years]) had bilateral breast reconstruction. The majority (41, 74.5%) underwent immediate reconstruction and DIEP flaps were utilised on 41 (74.5%) occasions. Major surgical complications occurred in 6 (10.9%) patients, all of which were postoperative vascular compromise of the flap. Failure to salvage the reconstruction occurred on 3 (5.5%) occasions resulting in a total flap failure rate of 2.7%. Obesity (>30 kg/m2) and age > 60 years were shown to have a statistically increased risk of developing postoperative complications (P < 0.05). Our experience demonstrates that abdominal free flaps for bilateral breast reconstruction fares well, with a flap failure rate of 2.7%. Increased body mass index and patient age (>60 years) were associated with higher complication rates. PMID:27504200

    Desmoid tumors are rare clonal fibroblastic proliferations that can arise at abdominal or extra-abdominal sites. Complete surgical resection is the primary treatment for resectable desmoid tumors, but a high rate of local recurrence has been reported even after complete resection. For patients with a recurrent tumor, the goals of treatment are to control the recurrence, maintain quality of life, and prolong survival. Radiofrequency ablation, radiotherapy, chemotherapy, and other medical therapies can be used as alternative methods, but there are considerable controversies over the roles of these methods in the management of desmoid tumors. High-intensity focused ultrasound (HIFU) is a minimally invasive and effective method for treatment of solid tumors. We used HIFU to treat four patients with intra-abdominal desmoid tumors from June 2011 to September 2013. Post-procedural pain was seen in all patients. One patient had an intra-abdominal abscess and another suffered a slight injury to the femoral nerve. The patients were followed up for 19-46 months (mean 34 months) until April 2015. The tumor in one patient disappeared, and no tumor progression was observed in the other patients. PMID:27033872

    Measuring the frequency of a defined outcome flaw for a series of patients undergoing operative procedures generates information for performance evaluation. Such data influence decisions to improve care if used responsibly. Wound infection (WI), bacterial invasion of the incision, is the most common infectious complication of surgical care and WI prevention has value because the complication affects economic, patient satisfaction, and patient functional status outcomes. WI frequency, one kind of surgical outcome flaw rate, is traditionally used to judge one aspect of surgical care quality. At the author's institution, global WI surveillance was conducted without interruption for 20 years. Results for 85,260 consecutive inpatient operations performed during the period showed that secular changes in infection rates occurred but were not necessarily caused by surgical care quality decrements.

    Objective: To evaluate the effectiveness of surgical simulation compared with other methods of surgical training. Summary Background Data: Surgical simulation (with or without computers) is attractive because it avoids the use of patients for skills practice and provides relevant technical training for trainees before they operate on humans. Methods: Studies were identified through searches of MEDLINE, EMBASE, the Cochrane Library, and other databases until April 2005. Included studies must have been randomized controlled trials (RCTs) assessing any training technique using at least some elements of surgical simulation, which reported measures of surgical task performance. Results: Thirty RCTs with 760 participants were able to be included, although the quality of the RCTs was often poor. Computer simulation generally showed better results than no training at all (and than physical trainer/model training in one RCT), but was not convincingly superior to standard training (such as surgical drills) or video simulation (particularly when assessed by operative performance). Video simulation did not show consistently better results than groups with no training at all, and there were not enough data to determine if video simulation was better than standard training or the use of models. Model simulation may have been better than standard training, and cadaver training may have been better than model training. Conclusions: While there may be compelling reasons to reduce reliance on patients, cadavers, and animals for surgical training, none of the methods of simulated training has yet been shown to be better than other forms of surgical training.

    A 39-year-old woman with stress urinary incontinence underwent a retropubic midurethral sling procedure. On postoperative day 1, she presented with persistent abdominal pain and fever. A computed tomographic scan showed subcutaneous lower abdominal wall edema and gas above the fascia suggesting a necrotizing soft tissue infection. She was surgically debrided twice, which included removal of the mesh sling on postoperative day 4. Cystoscopy suggested unrecognized bladder perforation had occurred during the initial procedure, and record rerevealed untreated bacteriuria before sling placement. The patient required wound vacuum therapy and a later secondary wound closure procedure. Six months after the initial surgery, she was reevaluated for stress urinary incontinence and underwent a transobturator midurethral sling procedure with resolution of these symptoms. Necrotizing postsurgical infection is a rarely described complication of midurethral slings. Treatment for this potentially life-threatening complication includes aggressive surgical debridement, administration of broad-spectrum antibiotic, removal of infected implants, and supportive therapy. Unrecognized bladder injury and preoperative bacteriuria are discussed as potential risk factors for postsling necrotizing infection. PMID:22543774

    Liver cirrhosis, a devastating liver fibrosis caused by hepatitis/inflammation or tumors, is a major comorbid factor in known surgery fields, such as cardiovascular and abdominal surgeries. It is important to review possible comorbid results in neurosurgical procedures in cirrhotic patients. In the reviewed literature, Child-Pugh and model for end-stage liver disease scores are commonly used in the assessment of surgical risks for cirrhotic patients undergoing abdominal, cardiovascular or neurosurgical procedures. The major categories of neurosurgery are traumatic brain injury (TBI), spontaneous intracranial hemorrhage (SICH), brain tumors, and spinal instrumentation procedures. TBI was reported with surgical mortality as high as 34.5% and a complication rate of 87.2%. For SICH, mortality ranged from 22.7% to 47.0%, while complications were reported to be 43.2%. Less is discussed in brain tumor patients; still the postoperative hemorrhage rate approached 26.7%. In spinal fusion instrumentation procedures, the complication rate was as high as 41.0%. Preoperative assessment and correction could possibly decrease complications such as hemorrhage, wound infection and other cirrhosis-related complications (renal, pulmonary, ascites and encephalopathy). In this study, we reviewed the neurosurgical-related literature with regard to liver cirrhosis as a prognostic factor influencing neurosurgical outcomes. PMID:26413225

    Vascular surgical training currently has to cope with various challenges, including restrictions on work hours, significant reduction of open surgical training cases in many countries, an increasing diversity of open and endovascular procedures, and distinct expectations by trainees. Even more important, patients and the public no longer accept a "learning by doing" training philosophy that leaves the learning curve on the patient's side. The Vascular International (VI) Foundation and School aims to overcome these obstacles by training conventional vascular and endovascular techniques before they are applied on patients. To achieve largely realistic training conditions, lifelike pulsatile models with exchangeable synthetic arterial inlays were created to practice carotid endarterectomy and patch plasty, open abdominal aortic aneurysm surgery, and peripheral bypass surgery, as well as for endovascular procedures, including endovascular aneurysm repair, thoracic endovascular aortic repair, peripheral balloon dilatation, and stenting. All models are equipped with a small pressure pump inside to create pulsatile flow conditions with variable peak pressures of ~90 mm Hg. The VI course schedule consists of a series of 2-hour modules teaching different open or endovascular procedures step-by-step in a standardized fashion. Trainees practice in pairs with continuous supervision and intensive advice provided by highly experienced vascular surgical trainers (trainer-to-trainee ratio is 1:4). Several evaluations of these courses show that tutor-assisted training on lifelike models in an educational-centered and motivated environment is associated with a significant increase of general and specific vascular surgical technical competence within a short period of time. Future studies should evaluate whether these benefits positively influence the future learning curve of vascular surgical trainees and clarify to what extent sophisticated models are useful to assess the level of

    Many surgical revolutions distinguish the history and evolution of surgery. They come in different sizes and exert a variable effect on the development and practice of the discipline. As science and technology rapidly evolve, so too does the creation of new paradigms, ideas and innovations or discoveries for the improvement of the surgical sciences. Surgical revolutions are not new, and have existed for centuries even though they have been more frequently recognized since the middle of the 19th century, 20th century and down to the present. Surgical revolutionaries are indispensable in the conception and completion of any surgical revolution. However, scientific and technological advances have supported the culmination of each revolution. PMID:18615311

    Purpose. To assess the feasibility and effectiveness of emergency endovascular treatment of abdominal aortic aneurysms (AAAs). Methods. During 36 months we treated, on an emergency basis, 30 AAAs with endovascular exclusion. In 21 hemodynamically stable patients preoperative CT angiography (CTA) was performed to confirm the diagnosis and to plan the treatment; 9 patients with hemorrhagic shock were evaluated with angiography performed in the operating room. Twenty-two Excluder (Gore) and 8 Zenith (Cook) stent-grafts (25 bifurcated and 5 aorto-uni-iliac) were used. The follow-up was performed by CTA at 1, 3, 6, and 12 months. Results. Technical success was achieved in 100% of cases with a 10% mortality rate. The total complication rate was 23% (5 increases in serum creatinine level and 2 wound infections). During the follow-up, performed in 27 patients (1-36 months, mean 15.2 months), 4 secondary endoleaks (15%) (3 type II, 2 spontaneously thrombosed and 1 under observation, and 1 type III treated by iliac extender insertion) and 1 iliac leg occlusion (treated with femoro-femoral bypass) occurred. We observed a shrinkage of the aneurysmal sac in 8 of 27 cases and stability in 19 of 27 cases; we did not observe any endotension. Conclusions. Endovascular repair is a good option for emergency treatment of AAAs. The team's experience allows correct planning of the procedure in emergency situations also, with technical results comparable with elective repair. In our experience the bifurcated stent-graft is the device of choice in patients with suitable anatomy because the procedure is less time-consuming than aorto-uni-iliac stent-grafting with surgical crossover, allowing faster aneurysm exclusion. However, further studies are required to demonstrate the long-term efficacy of endovascular repair compared with surgical treatment.

    A 53-year-old woman with liver cirrhosis and hepatocellular carcinoma underwent living donor liver transplantation. After transplantation, her hemoglobin and hematocrit levels decreased to 6.3 g/dl and 18.5%, respectively, during the course of 3 days. A contrast-enhanced abdominal computed axial tomography (CAT) scan showed a hemoperitoneum in the right perihepatic space with no evidence of abdominal wall hematoma or pseudoaneurysm formation. An angiogram of the deep circumflex iliac artery (DCIA) showed extravasation of contrast media along the surgical drain, which had been inserted during the transplantation procedure. Transcatheter embolization of the branches of the DCIA was successfully performed using N-butyl cyanoacrylate. PMID:19449069

    Alterations of the abdominal aorta are relatively common, particularly in older people. Technological advances in the fields of ultrasonography, computed tomography, angiography, and magnetic resonance imaging have greatly increased the imaging options for the assessment of these lesions. Because it can be done rapidly and is also non-invasive, ultrasonography plays a major role in the exploration of the abdominal aorta, from its emergence from the diaphragm to its bifurcation. It is indicated for the diagnosis and follow-up of various aortic diseases, especially aneurysms. It can be used to define the shape, size, and location of these lesions, the absence or presence of thrombi and their characteristics. It is also useful for monitoring the evolution of the lesion and for postoperative follow-up. However, its value is limited in surgical planning and in emergency situations. PMID:23396814

    Open surgical resection is the mainstay treatment for desmoid tumors. Laparoscopic resection is rarely used and not well described in the literature. We report a case of a single, 35-year-old woman who presented with palpable abdominal wall desmoid tumor. The patient had had laparoscopic cholecystectomy 2 years earlier, and the tumor was at the insertion site of the right upper quadrant trocar. The diagnosis was made by a Tru-Cut biopsy at another institution, after the lesion had increased in size and caused increased discomfort. The patient underwent successful laparoscopic resection of the tumor. This report aimed to promote laparoscopic resection of abdominal wall desmoid tumors, whenever feasible, and describe the laparoscopic technique. We believe this is the second case of laparoscopic excision of desmoid tumor reported in the English-language literature. PMID:26781534

    Introduction Low back pain is a common cause of medical consultation, and usually supposes a non-malignant prognostic. Presentation of case We report an atypical appearance of low back pain associated to shock and pulsatile abdominal mass that made us diagnose an abdominal aortic aneurysm as reason of vertebral lysis and pain. Discusion Surgical repair of contained AAA should be directed to secondary re-rupture prevention, with an approximate survival near to 100% at selected patients for elective surgery. Consequently, orthopedic surgery for back spine stabilization has to be elective in those cases when vertebral destruction is above 30% and clinic is directly related to spine instability. Conclusion We should consider AAA as other cause of low back pain and routinely examine the abdomen and seek complementary imaging proves when risk factors for AAA are present. PMID:25569196

After successfully addressing life-threatening complications, it is necessary to focus on the cosmetic and functional outcomes of the abdominal wall. Methods We performed a chart review of five cases treated in our institution. Results Five patients, ranging from seven to 18 years of age, underwent the following surgical approaches: simple approximation of the rectus abdominis fascia, the rectus abdominis sheath turnover flap, the placement of submuscular tissue expanders, mesh repair, or a combination of these techniques depending on the characteristics of each individual case. Conclusions Patients with severe congenital abdominal wall defects require individualized surgical treatment to address both the aesthetic and functional issues related to the sequelae of their defects.

    It is debated whether treating cancer patients in high-volume surgical centres can lead to improvement in outcomes, such as shorter length of hospital stay, decreased frequency and severity of post-operative complications, decreased re-admission, and decreased mortality. The dataset for this analysis was based on cancer registration and hospital discharge data and comprised information on 15,738 non-small-cell lung cancer patients resident and diagnosed in England in 2006-2010 and treated by surgical resection. The number of lung cancer resections was computed for each hospital in each calendar year, and patients were assigned to a hospital volume quintile on the basis of the volume of their hospital. Hospitals with large lung cancer surgical resection volumes were less restrictive in their selection of patients for surgical management and provided a higher resection rate to their geographical population. Higher volume hospitals had shorter length of stay and the odds of re-admission were 15% lower in the highest hospital volume quintile compared with the lowest quintile. Mortality risks were 1% after 30 d and 3% after 90 d. Patients from hospitals in the highest volume quintile had about half the odds of death within 30 d than patients from the lowest quintile. Variations in outcomes were generally small, but in the same direction, with consistently better outcomes in the larger hospitals. This gives support to the ongoing trend towards centralisation of clinical services, but service re-organisation needs to take account of not only the size of hospitals but also referral routes and patient access.

    This paper discusses the development of methods for computer-aided jaw surgery. Computer-aided jaw surgery allows us to incorporate the high level of precision necessary for transferring virtual plans into the operating room. We also present a complete computer-aided surgery (CAS) system developed in close collaboration with surgeons. Surgery planning and simulation include construction of 3D surface models from Cone-beam CT (CBCT), dynamic cephalometry, semi-automatic mirroring, interactive cutting of bone and bony segment repositioning. A virtual setup can be used to manufacture positioning splints for intra-operative guidance. The system provides further intra-operative assistance with the help of a computer display showing jaw positions and 3D positioning guides updated in real-time during the surgical procedure. The CAS system aids in dealing with complex cases with benefits for the patient, with surgical practice, and for orthodontic finishing. Advanced software tools for diagnosis and treatment planning allow preparation of detailed operative plans, osteotomy repositioning, bone reconstructions, surgical resident training and assessing the difficulties of the surgical procedures prior to the surgery. CAS has the potential to make the elaboration of the surgical plan a more flexible process, increase the level of detail and accuracy of the plan, yield higher operative precision and control, and enhance documentation of cases.

    Dual energy scanned projection radiography of the abdomen has been performed using an experimental line-scanned radiographic system. Digital images simultaneously obtained at 85 and 135 kVp are combined, using photoelectric/Compton decomposition algorithms to create images from which selected materials are cancelled. Soft tissue cancellation images have proved most useful in various abdominal imaging applications, largely due to the elimination of obscuring high-contrast bowel gas shadows. These techniques have been successfully applied to intravenous pyelography, oral cholecystography, intravenous abdominal arteriog-raphy and the imaging of renal calculi.

    Acute disorders of the abdominal aorta are potentially lethal conditions that require prompt evaluation and treatment. Computed tomography (CT) is the primary imaging method for evaluating these conditions because of its availability and speed. Volumetric CT acquisition with multiplanar reconstruction and three-dimensional analysis is now the standard technique for evaluating the aorta. MR imaging may be useful for select applications in stable patients in whom rupture has been excluded. Imaging is indispensable for diagnosis and treatment planning, because management has shifted toward endoluminal repair. Acute abdominal aortic conditions most commonly are complications of aneurysms and atherosclerosis. PMID:26526434

    Abdominal vascular catastrophes are among the most challenging and time sensitive for emergency practitioners to recognize. Mesenteric ischemia remains a highly lethal entity for which the history and physical examination can be misleading. Laboratory tests are often unhelpful, and appropriate imaging must be quickly obtained. A multidisciplinary approach is required to have a positive impact on mortality rates. Ruptured abdominal aortic aneurysm likewise may present in a cryptic fashion. A specific type of ruptured aneurysm, the aortoenteric fistula, often masquerades as the more common routine gastrointestinal bleed. The astute clinician recognizes that this is a more lethal variant of gastrointestinal hemorrhage. PMID:27133247

    Aneurysms are common in our increasingly elderly population, and are a major threat to life and limb. Until the advent of vascular reconstructive techniques, aneurysm patients were subject to an overwhelming risk of death from exsanguination. The first successful repair of an abdominal aortic aneurysm using an interposed arterial homograft was reported by Dubost in 1952. A milestone in the evolution of vascular surgery, this event and subsequent diagnostic, operative and prosthetic graft refinements have permitted patients with an unruptured abdominal aortic aneurysm to enjoy a better prognosis than patients with almost any other form of major systemic illness.

    We retrospectively examined the changes in hemodynamics, oxygen index and renal function along with the complications in 25 patients who had undergone endovascular stent graft placement (ESG) surgery for abdominal aortic aneurysm. During stent graft placement, mean arterial pressure decreased to 58 +/- 8 mmHg by increasing the dose of anesthetics and/or using vasodilators. Except for this intended hypotensive period, mean arterial pressure and heart rate were relatively stable and adequately maintained during surgical manipulation. Oxygenation index was well maintained. A patient with a high preoperative creatinine level underwent prophylactic hemodialysis postoperatively. In other patients except one who died in early postoperative period, both BUN and creatinine levels were kept within normal ranges. Four patients died postoperatively and the causes of the death in two patients are related to the surgical procedure; one with multiple emboli possibly due to released atheloma from the aortic wall during procedure, the other with sepsis due to infected stent graft. Although ESG is a well tolerated procedure, embolism is the most serious complication. Careful preoperative evaluation of the ascending arch and descending aortic wall and monitoring with transcranial doppler are necessary. PMID:11025953

    Background The purpose of the prospective study was to evaluate the effect of the nerve-sparing intrastromal abdominal hysterectomy bilateral salpingo-oophorectomy (ISTAH-BSO) on intraoperative, and postoperative complications namely blood loss and length of hospital stay. Methods Forty female patients were allocated by a block randomization method into a study group and a control group. The study group consisted of 20 patients who underwent ISTAH-BSO over a 2-year period. The control group included 20 patients who underwent conventional hysterectomy by the same surgeon during the same time frame. Both groups were followed for outcomes of interest, which included length of hospital stay, blood loss, and surgical complications. The participants in both groups were as similar as possible with respect to all known or unknown factors that might affect the study outcome. Results Postoperative hemoglobin levels were higher in the study group (blood loss 1.0 g/dL versus 1.4 g/dL in control group). Average hospital stay was significantly shorter in the study group (2.7 days versus 3.15 days in the control group, P = 0.028). No significant complications such as urinary fistula, vaginal vault prolapse, blood transfusion, or postoperative infections were identified in the study group. Conclusion The nerve-sparing ISTAH-BSO procedure described in this study has the potential to reduce length of hospital stay after abdominal hysterectomy by reducing blood loss and postoperative complications. Follow-up observations suggest that urinary function and sexual satisfaction are also preserved. Since this research, 175 cases have been performed, with an average of 5 years of follow-up. The outcomes of these cases have been reported as similar. PMID:23378786

    Integrated medical curricular changes are altering the historical regional anatomy approach to abdominal dissection. The renal system is linked physiologically and biochemically to the cardiovascular and respiratory systems; yet, anatomists often approach the urinary system as part of the abdomen and pelvic regions. As part of an integrated curriculum, the renal system must be covered relatively quickly after the thorax in the cadaver laboratory, often without the opportunity to fully appreciate the rest of the abdominal contents. This article provides dissection instructions that follow one of the historical surgical approaches for nephrectomy, including preservation of the posterior abdominal wall neurovasclature. Dissection procedures were developed for first-year medical students, intending this posterior approach to the kidneys to be their first introduction to the renal system. It has been successfully implemented with the first-year medical students at the University of New England, College of Osteopathic Medicine. Utilizing this posterior approach to the kidney enabled the study of the anatomy of the kidneys, suprarenal glands, and renal vessels, as well as the muscles of the lumbar spine, while maintaining the integrity of the anterior abdominal wall and peritoneal cavity for future gastrointestinal and reproductive system-based dissections.

    The generation, storage, transfer, and representation of image data in radiology are standardized by DICOM. To cover the needs of image guided surgery or computer assisted surgery in general one needs to handle patient information besides image data. A large number of objects must be defined in DICOM to address the needs of surgery. We propose an analysis process based on Surgical Workflows that helps to identify these objects together with use cases and requirements motivating for their specification. As the first result we confirmed the need for the specification of representation and transfer of geometric models. The analysis of Surgical Workflows has shown that geometric models are widely used to represent planned procedure steps, surgical tools, anatomical structures, or prosthesis in the context of surgical planning, image guided surgery, augmented reality, and simulation. By now, the models are stored and transferred in several file formats bare of contextual information. The standardization of data types including contextual information and specifications for handling of geometric models allows a broader usage of such models. This paper explains the specification process leading to Geometry Mesh Service Object Pair classes. This process can be a template for the definition of further DICOM classes.

  3. Recognition and management of abdominal compartment syndrome among German pediatric intensivists: results of a national survey

    2012-01-01

    Introduction Several decades ago, the beneficial effects of goal-directed therapy, which include decompressive laparotomy (DL) and open abdomen procedures in cases of intra-abdominal hypertension (IAH) in children, were proven in the context of closures of abdominal wall defects and large-for-size organ transplantations. Different neonatologic and pediatric disease patterns are also known to be capable of increasing intra-abdominal pressure (IAP). Nevertheless, a considerable knowledge transfer regarding such risk factors has hardly taken place. When left undetected and untreated, IAH threatens to evolve into abdominal compartment syndrome (ACS), which is accompanied by a mortality rate of up to 60% in children. Therefore, the present study looks at the recognition and knowledge of IAH/ACS among German pediatric intensivists. Methods In June 2010, a questionnaire was mailed to the heads of pediatric intensive care units of 205 German pediatric hospitals. Results The response rate was 62%. At least one case of IAH was reported by 36% of respondents; at least one case of ACS, by 25%. Compared with adolescents, younger critically ill children appeared to develop IAH/ACS more often. Routine measurements of IAP were said to be performed by 20% of respondents. Bladder pressure was used most frequently (96%) to assess IAP. Some respondents (17%) only measured IAP in cases of organ dysfunction and failure. In 2009, the year preceding this study, 21% of respondents claimed to have performed a DL. Surgical decompression was indicated if signs of organ dysfunction were present. This was also done in cases of at least grade III IAH (IAP > 15 mmHg) without organ impairment. Conclusions Although awareness among pediatricians appears to have been increasing over the last decade, definitions and guidelines regarding the diagnosis and management of IAH/ACS are not applied uniformly. This variability could express an ever present lack of awareness and solid prospective data. PMID

    Vomiting, often caused by mechanical intestinal obstruction, is common in dogs. Equivocal radiographic signs often necessitate repeat radiographs or additional imaging procedures. For our prospective, case-controlled, accuracy study, we hypothesized the following: (1) using computed tomography (CT), radiologists will be more sensitive and specific for detecting mechanical intestinal obstruction and recommending surgery compared to using radiographs; and (2) using measurements, radiologists will be more sensitive and specific using radiographs or CT for detecting mechanical intestinal obstruction and recommending surgery. Twenty dogs had abdominal radiographs and abdominal CT. Seventeen dogs had abdominal surgery and three dogs were not obstructed based on clinical follow-up. Confidence levels (five-point scale) of three experienced radiologists for mechanical intestinal obstruction and recommending surgery were recorded before and after making selected measurements. Eight dogs had surgically confirmed mechanical intestinal obstruction, and 12 dogs did not have obstruction. For detecting mechanical intestinal obstruction, CT was more sensitive (95.8% vs. 79.2%) and specific (80.6% vs. 69.4%) compared to radiographs, but the difference was not statistically significant. For recommending surgery, radiography was more sensitive (91.7% vs. 83.3%) and specific (83.3% vs. 72.2%) than using CT, but differences were not statistically significant. We reported objective CT measurements for predicting small mechanical intestinal obstruction. By incorporating these objective data, the diagnosis of mechanical intestinal obstruction changed in five of 120 instances (radiographs and CT). In no instance (0/120), did the objective data change the recommendation for surgery. Using CT or abdominal radiographs for the detection of canine mechanical intestinal obstruction is sensitive and specific when evaluated by experienced veterinary radiologists. PMID:27038072

    We present 2 cases of a 3-month-old girl and boy who were diagnosed with an infected pseudoaneurysm 2 months after undergoing left-sided modified Blalock-Taussig shunt (mBTS) operations for pulmonary atresia. Because the shunts in both cases were nearly obstructed, they underwent a 2-stage surgical approach: classic BTS operations through a right thoracotomy to establish sufficient pulmonary flow and infected graft removal through a median sternotomy after close observation of the state of the aneurysms. By utilizing autologous tissue from a different thoracic entry, both patients were successfully managed and recovered without any recurrence of infection. PMID:27106441

    Transversus abdominis plane (TAP) infiltration is a regional anesthesia technique that has been demonstrated to be effective for management of postsurgical pain after abdominal surgery. There are several different clinical variations in the approaches used for achieving analgesia via TAP infiltration, and methods for identification of the TAP have evolved considerably since the landmark-guided technique was first described in 2001. There are many factors that impact the analgesic outcomes following TAP infiltration, and the various nuances of this technique have led to debate regarding procedural classification of TAP infiltration. Based on our current understanding of fascial and neuronal anatomy of the anterior abdominal wall, as well as available evidence from studies assessing local anesthetic spread and cutaneous sensory block following TAP infiltration, it is clear that TAP infiltration techniques are appropriately classified as field blocks. While the objective of peripheral nerve block and TAP infiltration are similar in that both approaches block sensory response in order to achieve analgesia, the technical components of the two procedures are different. Unlike peripheral nerve block, which involves identification or stimulation of a specific nerve or nerve plexus, followed by administration of a local anesthetic in close proximity, TAP infiltration involves administration and spread of local anesthetic within an anatomical plane of the surgical site.

    Purpose: To compare the efficacy of surgery versus pulse-spray thrombolysis and angioplasty in patients with recurrent thrombosis of polytetrafluoroethylene (PTFE) dialysis access grafts. Methods: We analyzed 96 consecutive interventions for thrombosed PTFE dialysis access grafts in 18 patients. Primary patency after thrombolysis and angioplasty (n= 25) was compared with primary patency following thrombectomy alone (n= 50) or thrombectomy followed by graft revision (n= 21) using life-table analysis. A Cox proportional hazards model that accounted for graft age and number of previous interventions was used to generate the relative risk for recurrent occlusion following therapy. Results: Life-table analysis showed that patency after thrombolysis and angioplasty was greater than that following thrombectomy alone (p= 0.02). After accounting for the age of the graft and the number of previous interventions (average six per patient), the relative risk for recurrent occlusion [3.0; 95% confidence intervals (CI): 1.5, 6.4] was greater for thrombectomy alone than for thrombolysis/angioplasty [0.6; CI = 0.3, 1.3]. The relative risks of repeat occlusion following thrombolysis/angioplasty [0.6; CI = 0.3, 1.3] and thrombectomy/surgical revision [1.0; CI = 0.5, 1.7] were similar. Conclusion: Outcome data from our retrospective study on recurrent thrombosis of PTFE dialysis access grafts suggest that thrombolysis/angioplasty is superior to thrombectomy alone, and equivalent to thrombectomy/surgical revision.

    The rupture of an abdominal aortic aneurysm (rAAA) causes about 15000 deaths/year in the USA alone. Even though over the last 50 years progress in surgical techniques and in postoperative intensive care have been outstanding, the analysis of registries has shown either no decrease in the mortality rate for surgically treated rAAAs. Some reports asserted better out come for endovascular repair (EVAR) compared with surgery in case of rAAA. Despite this evidence, EVAR for rAAA remains prerogative of few centers worldwide. In conclusion only larger study or registry could assest the real role of EVAR in the management of rAAA. PMID:20523280

    The management of obstructive azoospermia resulting from intra-abdominal vasal obstruction poses a formidable surgical challenge. A number of surgical methods have been described to address this problem, including both open and laparoscopic approaches to mobilize and sometimes even re-route the abdominal vas deferens prior to performing a re-anastamosis. We present the first report, to our knowledge, of robotic intra-abdominal vasectomy reversal used to repair obstructive azoospermia resulting from prior laparoscopic vasectomy. In doing so, we summarize the techniques described previously in the literature and build upon this body of surgical experience by combining robotic-assisted laparoscopic mobilization of the vas with robotic vasovasostomy. We believe this novel approach for repairing intra-abdominal vasal defects minimizes morbidity, while at the same time obviating the need for the operating microscope, and thus represents a practical alternative to existing techniques.

    A surgical procedure performed during space flight would occur in a unique microgravity environment. Several experiments performed during weightlessness in parabolic flight were reviewed to ascertain the behavior of surgical bleeding in microgravity. Simulations of bleeding using dyed fluid and citrated bovine blood, as well as actual arterial and venous bleeding in rabbits, were examined. The high surface tension property of blood promotes the formation of large fluid domes, which have a tendency to adhere to the wound. The use of sponges and suction will be adequate to prevent cabin atmosphere contamination with all bleeding, with the exception of temporary arterial droplet streams. The control of the bleeding with standard surgical techniques should not be difficult.

    Posterior nutcracker syndrome is caused by the compression of left renal vein between the abdominal aorta and the vertebral body. Most seen symptoms are haematuria, left flank pain, abdominal pain and varicocele. The nutcracker syndrome may lead to left renal vein thrombosis due to blood congestion within compression of the vessel. Both endovascular and open surgical interventions can relieve symptoms; however, traditional surgical repair is still considered as the gold standard. Here, we present the surgical treatment of a 36-year old female with complaints of hypertension, hyperaldosteronism and diagnosed with posterior nutcracker syndrome. PMID:26892192

    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.

    Introduction Complex vesico-vaginal fistula (VVF) has a high recurrence rate and so the repair with graft tissues seems to be favorable. Amniotic membrane (AM) plays an increasing role as a scaffold for the repair of defect tissue due to its unique biological properties with regard to promoting wound healing. Material and methods An innovative surgical procedure for AM-assisted repair of a complex vesico-vaginal fistula as the Idea Stage following the IDEAL recommendations is presented. The development of amnion preparation and the involved surgical steps are described. Results We are able to report a successful repair of VVF by abdominal approach with an amniotic membrane graft. Good functional results, no adverse events and no graft rejection have been detected. Conclusions Favorable results confirm the technical simplicity, safety and efficacy of this procedure. Following the IDEAL recommendations, consecutive animal experiments and a cohort study are in progress. PMID:26855802

    ABSTRACT This study aims to investigate the causes and treatment experience of severe abdominal infection after orthotopic liver transplantation. Clinical data were retrospectively analysed in perioperative severe abdominal infection of 186 orthotopic liver transplantation cases from March 2004 to November 2011. Among the 186 patients, 16 cases had severe abdominal infection: five cases had bile duct anastomotic leakage-inducing massive hydrops and infection under liver interstice, 10 cases had extensive bleeding of surgical wound leading to massive haematocele and infection around the liver, and one case had postoperative lower oesophageal fistula leakage causing massive hydrops and infection under the left diaphragm. After definite diagnosis, 12 cases underwent surgery within three days, with no death. Among the four cases that underwent surgery three days after diagnosis, one case died of multiple-organ failure five days after abdominal cavity exploration, which was performed 21 days after liver transplantation. Severe abdominal infections after liver transplantation were the most common causes of death in perioperative liver transplantation. Comprehensive treatment with efficacious antibiotics, multiple-organ support, controlled surgical removal of the lesion, and adequate drainage establishment was the key to the entire treatment.

    Chronic periaortitis represents a unique pathogenic concept for three entities: Inflammatory Abdominal Aortic Aneurysm, Idiopathic Retroperitoneal Fibrosis and Perianeurysmal Retroperitoneal Fibrosis. The fundamental meaning of an inflammatory reaction to advanced atherosclerosis has been developed on the bottom of clinical and histological features. The triad of abdominal pain, weight loss and elevated inflammatory markers: erythrocyte sedimentation rate/C-reactive protein in patients with abdominal aortic aneurysms revealed on contrast-enhanced computer tomography is highly suggestive for inflammatory aneurysm. We report a case of a heavy-smoker adult male presented with suddenly abdominal symptoms suggestive for mesenteric ischemia which have proved to be due to inflammatory abdominal aortic aneurysm. The most favorable management of patients with inflammatory aneurysm is ambiguous. Surgical approach seems reasonable even supposing inflammatory aneurysm emerges less likely to rupture than the atherosclerotic variant. Corticosteroids are used in inoperable inflammatory aneurysm, even if is well known that this treatment does not change the long-term outcome of the disease. Surgical-open or Endovascular Repair of the aneurysm is the elective treatment. PMID:26793850

    Different methods for snap freezing surgical human tissue specimens exist. At pathology institutes with higher work loads, solid carbon dioxide, freezing sprays, and cryostat freezing are commonly used as coolants for diagnosing frozen tissue sections, whereas for tissue banking, liquid nitrogen or isopentane cooled with liquid nitrogen is preferred. Freezing tissues for diagnostic and research purposes are therefore often time consuming, laborious, even hazardous, and not user friendly. In tissue banks, frozen tissue samples are stored in cryovials, capsules, cryomolds, or cryocassettes. Tissues are additionally embedded using freezing media or wrapped in plastic bags or aluminum foils to prevent desiccation. The latter method aggravates enormously further tissue handling and processing. Here, we describe an isopentane-based workflow which concurrently facilitates tissue freezing and processing for both routine intra-operative frozen section and tissue banking and satisfies the qualitative demands of pathologists, cancer researchers, laboratory technicians, and tissue bankers.

    Intra-abdominal hypertension (IAH) contributes to organ dysfunction and leads to the development of the abdominal compartment syndrome (ACS). IAH and ACS are relatively frequent findings in patiens with severe acute pancreatitis (SAP) and are associated with deterioration in organ functions. The most affected are cardiovascular, respiratory and renal functions. The incidence of IAH in patients with SAP is approximately 60-80%. There is an accumulating evidence in human and animal studies that changes of perfusion, particularly to the microvasculature, are crucial events in the progression of acute pancreatitis (AP). The perfusion of the small and large intestine is impaired due to reduced arterial pressure, increased vascular resistence and diminished portal blood flow. Bacterial translocation has been described in patients with ACS, and this may apply to patients with SAP. Approximately 30-40% of SAP patients develop ACS because of pancreatic (retroperitoneal) inflammation, peripancreatic tissue edema, formation of fluid collections or abdominal distension. Surgical debridement was the preferred treatment to control necrotizing pancreatitis in the past. However, the management of necrotizing pancreatitis has changed over the last decade. The main objective of this article is to describe the association between IAH and AP and to emphasize this situation in clinical praxis as well (Fig. 1, Ref. 38). PMID:23406186

    Component separation is established for complex hernia repairs. This case presents early component separation and release of the anterior and posterior sheath to facilitate closure of the abdominal wall following emergency laparotomy, reinforcing the repair with a biological mesh. On Day 11 following an emergency laparotomy for penetrating trauma, this patient underwent component separation and release of the anterior and posterior sheath. An intra-abdominal biological mesh was secured, and the fascia and skin closed successfully. Primary abdominal closure can be achieved in patients with penetrating abdominal trauma with the use of component separation and insertion of intra-abdominal biological mesh, where standard closure is not possible.

    Injury to the small bowel is one of the tragic complications of radiotherapy. We performed a retrospective analysis of patients operated upon for stenosis, perforation, fistulization, and chronic blood loss of the small bowel after radiotherapy for multiple malignant diseases. In the period 1970 to 1982 in the Department of General Surgery of the St. Radboud University Hospital, Nijmegen, and the Department of Surgical Oncology of the State University, Groningen, 27 patients were treated surgically. Twenty patients presented with obstruction. In 17 patients a side-to-side ileotransversostomy was performed; in three the injured bowel was resected. Of the five patients with fistulization, three underwent a bypass procedure; in two cases the affected bowel was resected. In one patient with perforation, a resection was performed, as in a patient with chronic blood loss. Two of the 20 patients (10 per cent) in whom the diseased bowel was bypassed died postoperatively. Of the seven patients whose affected bowel was resected four (57 per cent) died of intra-abdominal sepsis. Management of the patient with chronic radiation enteritis is discussed. We conclude, on the basis of our experience, that in patients with obstruction and fistulization, a bypass procedure of the affected bowel is a safe method of treatment. In case of resection, the anastomosis should be performed during a second operation.

  5. Modification of an endovascular stent graft for abdominal aortic aneurysm

    NASA Astrophysics Data System (ADS)

    Moloye, Olajompo Busola

    Endovascular surgery is currently used to treat abdominal aortic aneurysms (AAA). A stent graft is deployed to exclude blood flow from the aneurysm sac. It is an effective procedure used in preventing aneurysm rupture, with reduced patient morbidity and mortality compared to open surgical repair. Migration and leakage around the device ("endoleak") due to poor sealing of the stent graft to the aorta have raised concerns about the long-term durability of endovascular repair. A preliminary study of cell migration and proliferation is presented as a prelude to a more extensive in vivo testing. A method to enhance the biological seal between the stent graft and the aorta is proposed to eliminate this problem. This can be achieved by impregnating the stent graft with 50/50 poly (DL-lactide co glycolic acid) (PLGA) and growth factors such as basic fibroblast growth factor (bFGF) or connective tissue growth factor (CTGF), at the proximal and distal ends. It is hypothesized that as PLGA degrades it will release the growth factors that will promote proliferation and migration of aortic smooth muscle cells to the coated site, leading to a natural seal between the aorta and the stent graft. In addition, growth factor release should promote smooth muscle cell (SMC) contraction that will help keep the stent graft in place at the proximal and distal ends. It is shown that a statistically significant effect of increased cell proliferation and migration is observed for CTGF release. Less of an effect is noted for bFGF or just the PLGA. The effect is estimated to be large enough to be clinically significant in a future animal study. The long term goal of this study is to reduce migration encounter after graft deployment and to reduce secondary interventions of EVAR especially for older patients who are unfit for open surgical treatment.

  6. Postthrombotic Syndrome: Surgical Possibilities

    Postthrombotic syndrome (PTS) is a late outcome of deep vein thrombosis characterized by cramping pain, swelling, hyperpigmentation, eczema, lipodermatosclerosis, and ulceration in the leg due to increased venous outflow resistance and reflux venous flow. Newer surgical and endovascular interventions have a promising result in the management of postthrombotic syndrome. Early surgical or endovascular interventions in appropriately selected patients may decrease the incidence of recurrent ulceration and skin changes and provide a better quality of life. Duplex and IVUS (intravenous ultrasound) along with venography serve as cornerstone investigative tools for assessment of reflux and obstruction. Venous obstruction, if present, should be addressed earlier than reflux. It requires endovenous stenting, endophlebectomy, or open bypass procedures. Venous stripping, foam sclerotherapy, radiofrequency, or laser ablation are used to abolish superficial venous reflux. Valvuloplasty procedures are useful for incompetent but intact deep venous valves, while transposition or axillary vein autotransplantation is done for completely destroyed valves. PMID:22084674

    Hip surgeries are some of the most common and successful orthopedic procedures. Although rarely, abdominal complications do occur and are associated with unfavorable outcomes.We aimed to identify and describe the severe abdominal complications that appear in patients under-going elective or traumatic hip surgery. A four year retrospective electronic database research identified 408 elective primary hip replacements,51 hip revisions and 1040 intra and extracapsular proximal femur fractures. Out of these, three males and 4 females between 64 - 84 years old were identified to have developed acute abdominal complications: perforated acute ulcer (3),acute cholecystitis (2), volvulus (1), toxic megacolon with peritonitis (1) and acute colonic pseudo-obstruction (1).Complications debuted 3 - 10 days after index orthopedic surgery. Acute perioperative abdominal complications are rarely encountered during orthopedic surgery. When these do occur, they do so almost exclusively in patients with hippathology, comorbidities and most often lead to life threatening situations. We thus emphasize the need for early identification and appropriate management by both orthopedic and general surgery doctors in order to improve patient safety. PMID:24742414

    Introduction Ostriches typically avoid humans in the wild, since they correctly assess humans as potential predators, and, if approached, often run away. However, ostriches may turn aggressive rather than run when threatened, especially when cornered, and may also attack when they feel the need to defend their offspring or territories. Presentation of case A 71-year-old male patient presented with intra abdominal injury sustained from being kicked in the abdominal wall by an ostrich. During laparotomy, were found free peritoneal effusion and perforation of the small intestine. Discussion The clinical history and physical examination are extremely important for diagnostic and therapeutic decision making. CT-scan is the most accurate exam for making diagnosis. Surgery is the treatment of choice, and is always indicated when there is injury to the hollow viscera. In general it is possible to suture the defect. Conclusion In cases of blunt abdominal trauma by animals is necessary to have a low threshold of suspicion for acute abdomen. PMID:25685344

  10. How to Surgically Remove the Permanent Mesh Ring after the Onstep Procedure for Alleviation of Chronic Pain following Inguinal Hernia Repair.

    A promising open inguinal hernia operation called Onstep was developed in 2005. The technique is without sutures to the surrounding tissue, causing minimal tension. A specific mesh is used with a memory recoil ring in the border, which may cause pain superficial to the lateral part of the mesh for slender patients. The aim of this study was to illustrate an easy procedure that alleviates/removes the pain. A male patient had persistent pain six months after the Onstep operation and therefore had a ring removal operation. The procedure is presented as a video and a protocol. At the eleven-month follow-up, the patient was free of pain, without a recurrence. It is advised to wait some months after the initial hernia repair before removing the ring, since the mesh needs time to become well integrated into the surrounding tissue. The operation is safe and easy to perform, which is demonstrated in a video. PMID:27298748

    Simulation in surgical training is playing an increasingly important role as postgraduate medical education programs navigate an environment of increasing costs of education, increased attention on patient safety, and new duty hour restrictions. In obstetrics and gynecology, simulation has been used to teach many procedures; however, it lacks a standardized curriculum. Several different simulators exist for teaching various routes and aspects of hysterectomy. This article describes how a formal framework of increasing levels of competencies can be applied to simulation in teaching the procedure of hysterectomy. PMID:27521885

    As hernias and abdominal wall defects have a variety of etiologies each with its own complications and comorbidities in various constellations, efficient treatment requires patient-oriented management. There is no recommended standard treatment and the very different clinical pictures demand an individualized interdisciplinary approach. Particularly in the case of complicated hernias, the planning of the operation should focus on the problems posed by the individual patient. Treatment mainly depends on the etiology of the hernia, immediate or long-term complications and the efficiency of individual repair techniques. Abdominal wall repair for recurrent herniation requires direct closure of the fascia generally using the sublay technique with a lightweight mesh. It is still unclear whether persistent inflammation, mesh dislocation, fistula formation or other long-term complications are due to certain materials or to the surgical technique. With mesh infections it has been shown to be advantageous to remove a polytetrafluoroethylene (PTFE) mesh, while the combination of systemic and local treatment appears to suffice for a polypropylene or polyester mesh. Heavier meshes in the sublay position or plastic reconstruction with autologous tissue are indicated as substitutes for the abdominal wall for giant hernias, repeated recurrences and large abdominal wall defects. A laparostoma is increasingly more often created to treat septic intra-abdominal processes but is very often responsible for a complicated hernia. If primary repair of the abdominal wall is not an option, resorbable material or split skin is used for coverage under the auspices of a planned hernia repair. PMID:20145901

    This manuscript reports the results of a nationwide survey of transplant surgeons in Germany, including the demographics, training, position, individual case loads, center volumes, program structure, professional practice, grade of specialization, workload, work hours, salary, and career expectations. We contacted all 32 German transplant centers that perform liver, kidney, and pancreas transplantation. Surgeons engaged in transplantation were asked to reply to the survey. Eighty-five surgeons responded, with a mean age of 44 ± 8 years, 13% of whom were female. The median transplant frequency per active transplant surgeon was relatively low, with 16 liver transplants, 15 kidney transplants, and three pancreas transplants. The median reported center volumes were 45 liver transplants, 90 kidney transplants, and five pancreas transplants per year. Most of the surgeons reported a primary focus on hepato-pancreato-biliary surgery, and only 10% of effective work time was actually dedicated to perform transplant surgeries. The majority of respondents estimated their weekly work hours to be between 55 and 66 h. When asked about their career satisfaction and expectations, most respondents characterized their salaries as inappropriately low and their career prospects as inadequate. This survey provides a first impression of the transplant surgery work force in Germany. PMID:25800065

    The lipid composition of pulmonary surfactant, ependymal cells and pulmonary tissue after surgery on the thorax in dogs was determined. 24 hrs after removal of one lung, in the other one there occurred changes in the quantity of respective classes of phospholipids of the pulmonary surfactant, manifesting themselves by a considerable drop in the amount of phosphatidylcholine (by 25%), phosphatidylethylamine (by 47%), phosphatidylglycerol (by 98%) and phosphatidylcholine: sphingomyelin ratio (by 63%), as well as by a rise in the amount of lysophosphatidylcholine (by 83%), phosphatidylserine (by 54%) and sphingomyelin (by 25%). In dogs receiving betamethasone in the post-operative period the changes were less intense: the amount of phosphatidylcholine decreased by 15%, phosphatidylethanolamine by 29%, phosphatidylglycerol by 94% and phosphatidylcholine: sphingomyelin ratio by 63%. The amount of lysophosphatidylcholine increased by 26.7%, phosphatidylserine by 29.1% and sphingomyelin by 22.2%. Similar changes were observed in the phospholipids of lining cells, while changes in the composition of phospholipids of pulmonary tissue in most cases appeared insignificant. Insignificant, too, were changes in the composition of neutral lipids of the tissular fractions examined. The described changes in dogs not receiving betamethasone correspond to those found in man in the course of acute respiratory insufficiency syndrome. Betamethasone was found to exert a protective effect on the phospholipids of pulmonary surfactant, soothing the biochemical changes brought about by surgical removal of one lung. PMID:3325943

    This paper presents an automated method of abdominal lymph node detection to aid the preoperative diagnosis of abdominal cancer surgery. In abdominal cancer surgery, surgeons must resect not only tumors and metastases but also lymph nodes that might have a metastasis. This procedure is called lymphadenectomy or lymph node dissection. Insufficient lymphadenectomy carries a high risk for relapse. However, excessive resection decreases a patient's quality of life. Therefore, it is important to identify the location and the structure of lymph nodes to make a suitable surgical plan. The proposed method consists of candidate lymph node detection and false positive reduction. Candidate lymph nodes are detected using a multi-scale blob-like enhancement filter based on local intensity structure analysis. To reduce false positives, the proposed method uses a classifier based on support vector machine with the texture and shape information. The experimental results reveal that it detects 70.5% of the lymph nodes with 13.0 false positives per case.

    Published records of the frequency of wound sepsis are often unreliable sources of information on the general frequency of this complication because of unstandardized methods of reporting and because of the various views of different investigators as to what constitutes sepsis. A method of infection reporting, its study and analysis are outlined. A survey of postoperative infections by this method for the years 1959, 1960 and 1961 revealed infection rates of 2.02%, 1.20% and 1.14%, respectively. For the same period the percentages of wound infections caused by Staph. aureus were 83.06%, 69.8% and 51.8%, respectively. The most prevalent phage types were 55/53/54 and 52/80/81/82, although types 80/81/82 and 80 were also involved. Infections with Gram-negative organisms were encountered more often in 1961 than in 1959. The majority of these were of mixed type, and followed abdominal surgery. There is need for more comprehensive study and analysis of postoperative wound sepsis and its complications. It was apparent from this study that, statistically, a relatively low rate of postoperative infections may mask a high rate following a specific surgical procedure. PMID:13954844

    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.

    Intestinal non-rotation has been recognized as a cause of obstruction in neonates and children. It is very rarely seen in the adult and assumes surgical significance owing to the potential risk of midgut or ileocecal volvulus. However, it can also cause significant intermittent abdominal pain in the adult. We describe six personally observed patients with this malformation and analyze 38 case reports published in the English and German literature since 1923. We establish that in the acute symptomatic form only emergency laparotomy can provide the correct diagnosis and decrease the risk of bowel disturbance. In the chronic forms, barium studies of the whole intestinal tract reveal varying degrees of midgut malrotation and the non-rotation is confirmed in each case. Also in these forms, exploratory laparotomy with a consequent staging of the abdominal situs is to be recommended. In the operation described by Ladd the ascending colon is sutured at the colon descendens and sigmoideum. After this procedure the mesenterial pedicle is fixed and the risk of midgut torsion remains minimal. All reported cases after surgery are symptom-free. PMID:1857952

    Penetrating gunshot wounds (GSWs) to the abdominal aorta are frequently lethal. Alternative management options for treatment of traumatic pseudoaneurysms of the abdominal aorta are illustrated by three patient case histories. Patient A sustained two GSWs to the abdomen (midepigastrium, right subcostal region). He was hypotensive in the field. Emergent laparotomy was undertaken with suture ligature of a celiac injury and distal pancreatectomy/splenectomy for a pancreatic injury. Postoperative abdominal CT for an intraabdominal infection with leukocytosis revealed a 4 cm traumatic pseudoaneurysm of the abdominal aorta that extended from the suprarenal aorta to the level of the renal arteries. Six weeks later, he underwent an open repair. Patient B sustained multiple GSWs to his right arm and right upper quadrant. He was hemodynamically stable. He underwent abdominal exploration for a grade 3 liver laceration. Postoperative abdominal CT revealed a supraceliac abdominal aortic pseudoaneurysm. An aortogram demonstrated a 1.5 cm defect in the aortic wall above the celiac trunk communicating with the inferior vena cava (IVC). He underwent endovascular repair with covered aortic stent graft. Patient C sustained multiple thoracoabdominal GSWs. He was hemodynamically stable. Emergent laparotomy revealed multiple left colonic perforations, two duodenal lacerations, and an unsalvageable left kidney laceration. Postoperatively, he developed a duodenal-cutaneous fistula with multiple intraabdominal abscesses. Serial CT scans revealed an enlarging infrarenal aortic pseudoaneurysm. He underwent angiographic coil embolization and intraarterial injection of thrombin into the pseudoaneurysm sac. The average time from injury to surgical treatment was 46 days (range 29-67). Postoperatively, none of the patients developed paraplegia. Advances in endovascular techniques have provided options to deal with traumatic pseudoaneurysms of the abdominal aorta.

    Context/objective: Abdominal lipectomy is performed by plastic surgeons to provide symptomatic, functional, and cosmetic relief for patients with excess abdominal tissue. However, there are few clinical outcome studies looking at the utility of this procedure: this is the first prospective oucomes study. Design: Patients who underwent abdominal lipectomy at the Bellflower Medical Center during a 12-month period (September 2004 through September 2005) were prospectively studied. Data were collected at the preoperative visit, during surgery, and at the one-week, one-month, and six-month postoperative visits. Outcome measures: Complications, both major (requiring rehospitalization or reoperation) and minor (requiring local outpatient care) were identified. To evaluate the impact on our patients' perceived health and well-being as well as body image, we administered the Short Form–36 Health Survey (SF-36) and the Multidimensional Body-Self Relations Questionnaire (MBSRQ) to participants at their preoperative and six-month postoperative visits. Results: For the 72 patients enrolled in the study, the postoperative major complication rate was 5.6% (four patients) and the minor complication rate was 27.8% (20 patients); 98.3% were happy to have had the surgery. Two components of the MBSRQ, feelings of attractiveness and body area satisfaction, showed significant improvement (p < 0.0001 for each) at six-month postoperative testing. No component of the SF-36 reached statistical significance between pre- and postoperative testing. Conclusion: Because the complication rate for cosmetic abdominoplasty in our study did not significantly differ from rates reported for other studies, and given our data on perceived patient satisfaction and improvement in outcomes, our study validates the utility of abdominal lipectomy for patients with symptomatic lower abdominal pannus.

  3. Ultrasound Screening for Abdominal Aortic Aneurysm

    PubMed Central

    2006-01-01

    Executive Summary Objective The aim of this review was to assess the effectiveness of ultrasound screening for asymptomatic abdominal aortic aneurysm (AAA). Clinical Need Abdominal aortic aneurysm is a localized abnormal dilatation of the aorta greater than 3 cm. In community surveys, the prevalence of AAA is reported to be between 2% and 5.4%. Abdominal aortic aneurysms are found in 4% to 8% of older men and in 0.5% to 1.5% of women aged 65 years and older. Abdominal aortic aneurysms are largely asymptomatic. If left untreated, the continuing extension and thinning of the vessel wall may eventually result in rupture of the AAA. Often rupture may occur without warning, causing acute pain. Rupture is always life threatening and requires emergency surgical repair of the ruptured aorta. The risk of death from ruptured AAA is 80% to 90%. Over one-half of all deaths attributed to a ruptured aneurysm take place before the patient reaches hospital. In comparison, the rate of death in people undergoing elective surgery is 5% to 7%; however, symptoms of AAA rarely occur before rupture. Given that ultrasound can reliably visualize the aorta in 99% of the population, and its sensitivity and specificity for diagnosing AAA approaches 100%, screening for aneurysms is worth considering as it may reduce the incidence of ruptured aneurysms and hence reduce unnecessary deaths caused by AAA-attributable mortality. Review Strategy The Medical Advisory Secretariat used its standard search strategy to retrieve international health technology assessments and English-language journal articles from selected databases to determine the effectiveness of ultrasound screening for abdominal aortic aneurysms. Case reports, letters, editorials, nonsystematic reviews, non-human studies, and comments were excluded. Questions asked: Is population-based AAA screening effective in improving health outcomes in asymptomatic populations? Is AAA screening acceptable to the population? Does this affect the

    Despite the frequency of functional abdominal pain, potentially dangerous causes of abdominal pain need to be excluded. Medical history and clinical examination must focus on red flags and signs for imflammatory or malignant diseases. See the patient twice in the case of severe and acute abdominal pain if lab parameters or radiological examinations are normal. Avoid repeated and useless X-ray exposure whenever possible. In the case of subacute or chronic abdominal pain, lab tests such as fecal calprotectin, helicobacter stool antigen and serological tests for celiac disease are very useful. Elderly patients may show atypical or missing clinical signs. Take care of red herrings and be skeptical whether your initial diagnosis is really correct. Abdominal pain can frequently be an abdominal wall pain. PMID:26331201

    Major imperatives regarding quality of patient care and patient safety are impacting surgical care and surgical education. Also, significant emphasis continues to be placed on education and training to achieve proficiency, expertise, and mastery in surgery. Simulation-based surgical education and training can be of immense help in acquiring and maintaining surgical skills in safe environments without exposing patients to risk. Opportunities for repetition of tasks can be provided to achieve pre-established standards, and knowledge and skills can be verified using valid and reliable assessment methods. Also, expertise and mastery can be attained through repeated practice, specific feedback, and establishment of progressively higher learning goals. Simulation-based education and training can help surgeons maintain their skills in infrequently performed procedures and regain proficiency in procedures they have not performed for a period of time. In addition, warm-ups and surgical rehearsals in simulated environments should enhance performance in real settings. Major efforts are being pursued to advance the field of simulation-based surgical education. New education and training models involving validation of knowledge and skills are being designed for practicing surgeons. A competency-based national surgery resident curriculum was recently launched and is undergoing further enhancements to address evolving education and training needs. Innovative simulation-based surgical education and training should be offered at state-of-the-art simulation centers, and credentialing and accreditation of these centers are key to achieving their full potential.

    The management of traumatic abdominal wall hernias is controversial. We performed a MEDLINE search and report a personal series of 10 patients. Cases were classified according to the cause of injury. Fifty-six percent were caused by car accidents and 14% by bicycle accidents. Diagnosis was clinical in 22% and surgical in 13% and intra-abdominal lesions were found in 67%. Treatment was delayed in 12%. In our series, 55% were lumbar hernias due to traffic accidents and all were associated with pelvic fracture. Treatment was delayed in 50%, including laparoscopic surgery with good results. In conclusion, traumatic hernias due to road traffic accidents are frequently associated with intra-abdominal lesions. The diagnostic technique of choice is computed tomography and delayed surgery (laparoscopy) is an effective option. PMID:18021624

    Esophageal duplication cysts are congenital anomalies of the foregut that are rarely found in the abdomen. An accurate preoperative diagnosis is not always possible, so the definitive diagnosis can be made by histologic examination of the surgical specimen. We experienced a case of Intra-abdominal esophageal duplication cyst in a 52-year-old female, who initially presented with an esophageal submucosal tumor on upper gastrointestinal endoscopy. She did not have any gastrointestinal symptoms. Barium esophagography, chest computed tomography scan and endoscopic ultrasonography demonstrated the cystic lesion in the intra-abdominal esophagus. Transhiatal enucleation of the lesion was performed successfully via the abdominal approach with no postoperative complications. Histologic study showed that the cyst wall contained a two-layered muscle coat and the surface of the lumen was lined by pseudo-ciliated columnar epithelium. The patient has been doing well without any complaints for 3 months of follow-up period. PMID:16385665

    Adrenal hemangioma is an extremely rare benign and non-functioning neoplasm of the adrenal gland. We report a case of a 71-year-old woman admitted for intermittent abdominal pain and abdominal distension associated with vomiting and chronic constipation for 5 years. Physical examination revealed a large abdominal mass. Both computed tomography scan and magnetic resonance imaging suggested hemangioma in the right lobe of the liver. Laboratory examinations and tumour markers were within normal limits, except for hypochromic microcytic anemia. The mass was removed intact by conventional surgery and histopathology revealed a cavernous hemangioma of the adrenal gland with no signs of malignancy. Surgical resection was curative, with no recurrence at the 2-year follow-up. PMID:26600897

    A study was performed to determine the value of peritoneal lavage in the acute abdomen not related to trauma. Lavage was performed in 33 patients in the evaluation of abdominal pain of sufficient degree to warrant consideration for surgical intervention. Peritoneal lavage was truly positive or truly negative in 64% of the cases. It showed false negative results in 28% and false positive results in 8%. The lavage was most accurate in the evaluation of appendicitis, colonic disease, and intra abdominal bleeding. It was highly inaccurate in the evaluation of cholecystitis and peptic ulcer disease. It was concluded that the peritoneal lavage can be a useful adjunct in the evaluation of patients with abdominal pain and should be considered in difficult diagnostic problems but not routinely employed.

    Cervicothoracic Sympathectomy is a common indication in the treatment of Raynaud Syndrome, Palmer Hyperhidrosis or Acute Ischemia of the superior limb. Nonetheless, almost a century ago it represented one of the first innovative attempts in curing coronary heart disease. Nowadays, this indication is no more than a footnote in a volume on the History of Medicine, and a trivia fact for medical history enthusiasts. The operation's history is rather conflicting. A young Romaninan surgeon, Victor Gomoiu seems to have come up with the idea, in the early 20th century. However, his contribution remains unknown, after his successful collaboration with the famous surgeon and anatomist, Thoma Ionescu unfortunately turns into a dispute. This procedure was once thought cutting-edge. Furthermore it is the starting point for cardiovascular surgery. Whoever sparked the idea, gains an important place in the hall of fame of international surgery, that is why it is important to know its creator. PMID:27544937

    The management of encrusted ureteral stents is costly, time consuming and may be risky for the patient and challenging for the urologist. Treatment modalities for encrusted stents include extracorporeal shock wave lithotripsy, cystolithopaxy, rigid or flexible ureteroscopy with intracorporeal lithotripsy, percutaneous nephrolithotomy, open surgery, and a combination of those methods. In this study we describe the management of severe forgotten encrusted ureteral stents in 3 female patients using a prone split-leg position. This position allows us to effectively treat any site and degree of stent encrustation in a single-session approach with the patient in the same position during the whole procedure. All patients were rendered stent and stone free. No complications occurred. PMID:26279723

    Chronic abdominal pain is a common pediatric condition affecting 20% of the pediatric population worldwide. Most children with this disorder are found to have no specific organic etiology and are given the diagnosis of functional abdominal pain. Well-designed clinical trials have found hypnotherapy and guided imagery to be the most efficacious treatments for this condition. Hypnotic techniques used for other somatic symptoms are easily adaptable for use with functional abdominal pain. The author discusses 2 contrasting hypnotic approaches to functional abdominal pain and provides implications for further research. These approaches may provide new insights into this common and complex disorder. PMID:21922712

    Primary soft tissue tumours arising from the abdominal wall are uncommon and surgical excision of such tumours can result in large abdominal wall defects. There are many techniques available for abdominal wall repair following tumour excision, each having its own advantages and disadvantages. The options range from direct closure to the use of tissue flap reconstructions and/or prosthetic meshes. Currently, synthetic material such as polypropylene mesh is a common choice for closure of abdominal wall defects after tumour excision. Biological meshes are an alternative option for repair, and this report outlines two cases of abdominal wall repair using the porcine intestinal submucosa biological graft following excision of abdominal wall tumours. There was no evidence of infection, recurrence, seroma or hernias at 2-year follow-up. Following excision of soft tissue tumours of the abdominal wall, biological reconstructions can be successfully used to bridge the defect with minimal morbidity. PMID:26109681

    The management of abdominal wall repair continues to present a challenging problem, especially in the repair of major defects. Many abdominal wall defects can be repaired by primary closure; however, if the defect is large and there is a tension on the closure of the wound, the use of prosthetic materials becomes indispensable. Many studies have been performed with various materials and implant techniques, without the comparison of their degrees of success, based on sound meta-analysis and/or inclusive epidemiologic studies. This review covered the effectiveness of recent advances in prosthetic materials and implant procedures used in repair of abdominal wall, based on biomechanical properties and economic aspects of reconstructed large abdominal wall defects and hernias in animals. The presented results in this review helped to reach treatment algorithms that could maximize outcomes and minimize morbidity. PMID:27293982

    Only vitamin K antagonists could be applied as oral anticoagulants over the past six decades. Coumarols have narrow therapeutic range, and unpredictable anticoagulant effects are resulted by multiple drug interactions. Therefore, regular routine monitoring of the international normalized ratio is necessary. There are two groups of factor-specific anticoagulants: molecules with anti-FIIa (dabigatran) and anti-FXa (rivaroxaban, apixaban and edoxaban) effect. Author summarizes the most important clinical features of the new oral anticoagulants, their indications and the possibilities of laboratory controls. Bleedings are the most important side effects of anticoagulants. This review summarizes the current published evidences for new oral anticoagulants reversal (non-specific and specific) agents, especially in cases with severe acute bleedings or urgent surgery procedures. It reports on how to use inhibitors, the recommended doses and the most important clinical results. The review focuses on idarucizumab - already approved by the U.S. Food and Drug Administration and the European Medicines Agency - which has a key role as the first specific inhibitor of dabigatran.

    Five related Boer goat kids (≤4 months of age) were presented to the University of Missouri, Veterinary Teaching Hospital (MU-VMTH) with epiphora and blepharospasm of several weeks duration and commencing prior to 1 month of age in all animals. Clinical examination confirmed euryblepharon and entropion bilaterally in two females and one male and unilaterally in two female kids. Deep stromal corneal ulceration was present in two eyes, and corneal granulation tissue and fibrosis were present in half (5/10) the affected eyes. A combination Hotz-Celsus and lateral eyelid wedge resection procedure was performed on all affected eyelids. Recheck examinations and long-term follow-up confirmed resolution of the entropion, preservation of normal eyelid conformation, and restoration of ocular comfort. Pedigree analysis ruled out sex-linked and autosomal dominant inheritance patterns; a specific mode of inheritance could not be determined. The Boer goat breed may be at increased risk for the development of entropion. This cases series represents the first report of entropion in the caprine species. PMID:25338664
