    Introduction The advantages of a minimally invasive nephrectomy are a faster recovery and better quality of life for the donors. Until recently, the majority of donor nephrectomies in Poland were done by open surgery. Aim To present a single centre experience in hand-assisted laparoscopic donor nephrectomy (HALDN). Material and methods The first videoscopic left donor nephrectomy in Poland was performed in our department in 2003 using a hand-assisted retroperitoneal approach. From 2011, we changed the method to a transperitoneal approach and started to harvest also right kidneys. Since then, it has become the method of choice for donor nephrectomy and has been performed in 59 cases. Preoperatively, kidneys were assessed by scintigraphy and by angio-computed tomography. We harvested 32 left and 27 right kidneys. There were double renal arteries in 2 cases and triple renal arteries in 1 case. The warm ischaemia time (WIT) was 80–420 s (average 176.13 s); operative time was 85–210 min (average 140 min). Results All procedures were uncomplicated, and all donors were discharged after 2–8 days with normal creatinine levels. The average follow-up period lasted 23 months (1–51 months). Out of all of the cases, 1 case had two minor complications, while all others were uneventful. None of the donors were lost to follow-up. All of the kidneys were transplanted. There were 2 cases of delayed graft function (DGF) and 2 cases of ureter necrosis. One of those kidneys was lost in the third postoperative week. Conclusions Our limited experience shows that HALDN is a safe method and should be used routinely instead of open surgery. PMID:28194249

    Abstract Complete situs inversus is a rare congenital anomaly characterized by transposition of organs. We report a case of renal transplantation using a kidney from a living complete situs inversus donor. The recipient was a 59-year-old female with end-stage renal disease because of type 2 diabetes mellitus. The donor was the 56-year-old sister of the recipient with complete situs inversus. CT angiogram of the abdomen and pelvis showed complete situs inversus and an otherwise normal appearance of the bilateral kidneys with patent bilateral single renal arteries and longer renal vein in the right kidney. The patient was taken to the operating room for a hand-assisted laparoscopic right donor nephrectomy. The patient tolerated the procedure well and was discharged home in good condition on postoperative day 1. The recipient experienced no episodes of acute rejection or infection, with serum creatinine levels of 0.8–1.2 mg/dL. Laparoscopic donor nephrectomy in a patient with complete situs inversus remains a technically feasible operation and the presence of situs inversus should not preclude consideration for living kidney donation.

    Objectives: We describe a technique of doubly clipping the distal ureter during hand-assisted laparoscopic donor nephrectomy (HALDN) to prevent urine accumulation, thereby simplifying renal hilar division and potentially decreasing the graft warm ischemic time. Methods: A technique of placing polymer-locking clips across the distal ureter prior to division was developed to prevent urine accumulation and the need for suctioning during critical hilar vessel division. Results: We found that ureteral clipping and the elimination of urine accumulation simplified renal hilar division. Retrospective assessment of a series of 27 sequential HALDNs (15 without and 12 with clipping) demonstrated similar estimated blood loss, total operative and warm ischemic times (P=0.13 to 0.18). No adverse impact on graft viability or recipient outcome was observed. Conclusion: Distal ureter clipping to prevent urine accumulation around the renal hilum during HALDN is safe and helpful.

    The benefits of laparoscopic living-donor nephrectomy (LDN) are well described, while similar data on hand-assisted laparoscopic living-donor nephrectomy (HALDN) are lacking. We compare hand-assisted laparoscopic living-donor nephrectomy with open donor nephrectomy. One hundred consecutive hand-assisted laparoscopic living-donor nephrectomy (10/98-8/01) donor/recipient pairs were compared to 50 open donor nephrectomy pairs (8/97-1/00). Mean donor weights were similar (179.6 +/- 40.8 vs. 167.4 +/- 30.3 lb; p = NS), while donor age was greater among hand-assisted laparoscopic living-donor nephrectomy (38.2 +/- 9.5 vs. 31.2 +/- 7.8 year; p < 0.01). Right nephrectomies was fewer in hand-assisted laparoscopic living-donor nephrectomy [17/100 (17%) vs. 22/50 (44%); p < 0.05]. Operative time for hand-assisted laparoscopic living-donor nephrectomy (3.9 +/- 0.7 vs. 2.9 +/- 0.5 h; p < 0.01) was longer; however, return to diet (6.9 +/- 2.8 vs. 25.6 +/- 6.1 h; p < 0.01), narcotics requirement (17.9 +/- 6.3 vs. 56.3 +/- 6.4h; p < 0.01) and length of stay (51.7 +/- 22.2 vs. 129.6 +/- 65.7 h; p < 0.01) were less than open donor nephrectomy. Costs were similar ($11072 vs. 10840). Graft function and 1-week Cr of 1.4 +/- 0.9 vs. 1.6 +/- 1.1 g/dL (p = NS) were similar. With the introduction of HALDN, our laparoscopic living-donor nephrectomy program has increased by 20%. Thus, similar to traditional laparoscopic donor nephrectomy, hand-assisted laparoscopic living-donor nephrectomy provides advantages over open donor nephrectomy without increasing costs.

    We report a living donor who underwent laparoscopic nephrectomy using a hand-assisted device (HALD). At preoperative arteriography the donor showed a renal artery aneurysm. The patient was a 37-year-old female, 166 cm height, white, weighing 87 kg, HLA identical to the recipient. HALD was indicated due to the better visualization of renal pedicle and greater security in an obese patient. Renal artery aneurysm is a rare condition, with many possible complications. The method proved to be adequate and safe for donor nephrectomy, despite a renal artery aneurysm.

    The removal of a donor kidney by laparoscopic nephrectomy is a safe method that is widely used, mainly in left donor nephrectomy. However, for right donor nephrectomy where the right renal vein is short, open surgery has been more frequently described in the literature. Our objective was to describe our experience with 31 renal transplantations using 2 different techniques in right donor nephrectomy. In the period ranging from February 2002 to June 2005, we performed, 31 hand-assisted laparoscopic right donor nephrectomies. Twenty-five were performed by the method where the assistant used his hand to assist the surgery and 6 were by the laparoscopic method assisted by the first surgeon. The right donor nephrectomies assisted either by the hand of the assistant or the surgeon showed similar results. All recipients displayed diuresis in the immediate postoperative period. The serum creatinine level at 1 week after transplantation was 1.90 mg/dL (+/-1.55). Although the handling techniques are similar, we concluded that laparoscopic nephrectomy assisted by the surgeon is more adequate for right kidney extraction. It can be performed either by a resident doctor or a surgeon of the transplantation team, with or without experience in nephrectomy for transplantation.

    THERE ARE TWO APPROACHES TO LAPAROSCOPIC DONOR NEPHRECTOMY: standard laparoscopic donor nephrectomy (LDN) and hand-assisted laparoscopic donor nephrectomy (HALDN). In this study we report the operative statistics and donor complications associated with LDN and HALDN from large-center peer-reviewed publications. Methods. We conducted PubMed and Ovid searches to identify LDN and HALDN outcome studies that were published after 2004. Results. There were 37 peer-reviewed studies, each with more than 150 patients. Cumulatively, over 9000 patients were included in this study. LDN donors experienced a higher rate of intraoperative complications than HALDN donors (5.2% versus. 2.0%, P < .001). Investigators did not report a significant difference in the rate of major postoperative complications between the two groups (LDN 0.5% versus HALDN 0.7%, P = .111). However, conversion to open procedures from vascular injury was reported more frequently in LDN procedures (0.8% versus 0.4%, P = .047). Conclusion. At present there is no evidence to support the use of one laparoscopic approach in preference to the other. There are trends in the data suggesting that intraoperative injuries are more common in LDN while minor postoperative complications are more common in HALDN.

    Background: Hand-assisted laparoscopic donor nephrectomy is a minimally invasive procedure for living kidney donation. The surgeon operative volume is associated with postoperative morbidity and mortality. We evaluated the risk factors associated with decreased renal function after hand-assisted laparoscopic donor nephrectomy performed by a single experienced surgeon. Methods: We included living renal donors who underwent hand-assisted laparoscopic donor nephrectomy by a single experienced surgeon between 2006 and 2013. Decreased renal function was defined as an estimated glomerular filtration rate (eGFR) of < 60 mL/min/1.73 m2 on postoperative day 4. The donors were categorized into groups with postoperative eGFR < 60 mL/min/1.73 m2 or ≥ 60 mL/min/1.73 m2. Univariate and multivariate logistic regression analyses were performed to evaluate the risk factors associated with decreased renal function after hand-assisted laparoscopic donor nephrectomy. The hospital stay duration, intensive care unit admission rate, and eGFR at postoperative year 1 were evaluated. Results: Of 643 patients, 166 (25.8%) exhibited a postoperative eGFR of < 60 mL/min/1.73 m2. Multivariate logistic regression analysis demonstrated that the risk factors for decreased renal function were age [odds ratio (95% confidence interval), 1.062 (1.035-1.089), P < 0.001], male sex [odds ratio (95% confidence interval), 3.436 (2.123-5.561), P < 0.001], body mass index (BMI) [odds ratio (95% confidence interval), 1.093 (1.016-1.177), P = 0.018], and preoperative eGFR [odds ratio (95% confidence interval), 0.902 (0.881-0.924), P < 0.001]. There were no significant differences in postoperative hospital stay duration and intensive care unit admission rate between the two groups. In addition, 383 of 643 donors were analyzed at postoperative year 1. Sixty donors consisting of 14 (5.0%) from the group of 279 donors in eGFR ≥ 60 mL/min/1.73 m2, and 46 (44.2%) from the group of 104 donors in eGFR < 60 mL/min/1

    Endoscopic techniques have contributed to early recovery and increased quality of life (QOL) of live kidney donors. However, laparoscopic donor nephrectomy (LDN) may have its limitations, and hand-assisted retroperitoneoscopic donor nephrectomy (HARP) has been introduced, mainly as a potentially safer alternative. In a randomized fashion, we explored the feasibility and potential benefits of HARP for right-sided donor nephrectomy in a referral center with longstanding expertise on the standard laparoscopic approach. Forty donors were randomly assigned to either LDN or HARP. Primary outcome was operating time, and secondary outcomes included QOL, complications, pain, morphine requirement, blood loss, warm ischemia time, and hospital stay. Follow-up time was 1 year. Skin-to-skin time did not significantly differ between both groups (162 vs. 158 min, P = 0.98). As compared to LDN, HARP resulted in a shorter warm ischemia time (2.8 vs. 3.9 min, P < 0.001) and increased blood loss (187 vs. 50 ml, P < 0.001). QOL, complication rate, pain, or hospital stay was not significantly different between the groups. Right-sided HARP is feasible but does not confer clear benefits over standard right-sided LDN yet. Further studies should explore the value of HARP in difficult cases such as the obese donor and the value of HARP for transplantation centers starting a live kidney donation program (Dutch Trial Register number: NTR3096). Nevertheless, HARP is a valuable addition to the surgical armamentarium in live donor surgery.

    We report our experience with hand-assisted laparoscopic donor nephrectomy (HALDN) and compare to our results with conventional open donor nephrectomy (ODN). From February 2000 to January 2003, 100 patients (M:F 54:46) underwent HALDN at the Kangnam St. Mary's hospital. These patients were divided into early (1st 50 cases) and late (2nd 50 cases) groups. These cohorts were compared with 40 patients (M:F 26:14) who underwent ODN via a flank incision from January 1999 to January 2003 at the same institution. Patient data were obtained from medical record review and personal and telephone interviews. The HALDN was completed successfully in 99 donors. The mean operative times (minutes) were 225 (140-425), 178 (135-250), and 188 (140-260) in the early HALDN, late HALDN, and ODN groups, respectively (P<0.05). The mean warm ischemia times (seconds) of the ODN (135+/-52.4) and late HALDN (150+/-76.7) groups were shorter than that of the early HALDN group (207+/-88.5) (P<0.05). On average, a regular diet was resumed after 2.1, 1.89, and 2.05 days, respectively. (P<0.05), and patients were discharged home 4.12, 4.04, and 6.8 days (P<0.05) after surgery in the early HALDN, late HALDN, and ODN groups. Analgesic use was significantly reduced in the HALDN group in comparison with ODN (P<0.05). Complications consisted of two cases of chyloperitoneum and one case each of open conversion, transfusion, prolonged ileus, liver enzyme elevation, and recipient ureteral necrosis in the early HALDN group; one case of subcutaneous emphysema in the late HALDN group; and one case each of transfusion and liver enzyme elevation in the ODN group. The mean donor (1 and 30 days) and recipient (6 months) serum creatinine concentrations did not differ among the groups (P>0.05). The HALDN appears to be a safe, technically feasible, and effective alternative to conventional ODN. The procedure may offer several advantages over conventional ODN in terms of less postoperative pain, shorter convalescence

    Introduction: Minimally invasive surgery has revolutionized general surgery during the past 10 years. However, for more advanced surgical procedures, the acceptance of the minimally invasive approach has been slower than expected. Advanced laparoscopic surgery is complex and time-consuming. The major drawbacks of laparoscopic surgery are two-dimensional view, lack of depth perception and loss of tactile sensation. This has led to the innovation of hand-assisted laparoscopic surgery (HALS). The objective of the present study was to determine that safety of HALS. Materials and Methods: We preformed 18 HALS procedures in our department between July 2003 and January 2005 on patients who had given their informed consent for the use of Gelport. Out of these, 15 were colectomy, 2 nephrectomy and 1 splenectomy. Out of the 18 patients, 13 were males and 5 were females with the age group ranging from 44 to 72 years. Results: Hand-assisted laparoscopic surgery could be completed in 17 patients maintaining all the oncological principals of surgery. The mean operating times were 120 min for right haemicolectomy, 135 min for left colectomy, 150 min for splenectomy, and 150 min for nephrectomy. The patient undergoing radical nephrectomy by HALS had to be converted to open surgery. As the tumour was large and adherent to the spleen and posterior peritoneal wall. Postoperative recovery was excellent with an average hospital stay of 5 days. Histopathology report showed wide clearance and till date we have a good follow up of 30–380 days. Conclusion: Hand-assisted laparoscopic surgery allows tactile sensation and depth perception thereby may simplify the complex procedures. This may result in reduction of operating time and conversion rates at the same time maintaining all the oncological principles. Hand-assisted laparoscopic surgery strikes a perfect balance between an extended open laparotomy incision and an excessively tedious laparoscopic exercise. Hand assistance is an

    Although the laparoscopic technique is an accepted method for elective splenectomy, it is controversial in the setting of trauma. A few reports have described laparoscopic splenorrhaphy for trauma, but none have performed laparoscopic splenectomy for splenic rupture. When the spleen is injured, vascular control and poor visibility due to bleeding present obstacles to laparoscopy. The development of the hand-assist device has helped surgeons make the transition from laparotomy to laparoscopy because of the advantages it provides, such as tactile sensation and immediate vascular control. We utilized these benefits of the hand-assist device to convert a laparoscopic operation to a hand-assisted laparoscopic operation and were thus able to avoid a laparotomy. We report a case in which the hand-assist device was used as an alternative to conversion during a laparoscopic splenectomy for ruptured spleen.

    Laparoscopic live donor nephrectomy (LDN) has removed disincentives of potential donors and may bear the potential to increase kidney donation. Multiple modifications have been made to abbreviate the learning curve while at the same time guarantee the highest possible level of medical quality for donor and recipient. We reviewed the literature for the evolution of the different LDN techniques and their impact on donor, graft and operating surgeon, including the subtleties of different surgical accesses, vessel handling and organ extraction. We performed a literature search (PubMed, DIMDI, medline) to evaluate the development of the LDN techniques from 1995 to 2003. Today more than 200 centres worldwide perform LDN. Hand-assistance has led to a spread of LDN. Studies comparing open and hand-assisted LDN show a reduction of operating and warm ischaemia times for the hand-assisted LDN. Different surgical access sites (trans- or retroperitoneal), different vessel dissection approaches, donor organ delivery techniques, delivery sites and variations of hand-assistance techniques reflect the evolution of LDN. Proper techniques and their combination for the consecutive surgical steps minimize both warm ischaemia time and operating time while offering the donor a safe minimally invasive laparoscopic procedure. LDN has breathed new life into the moribund field of living kidney donation. Within a few years LDN could become the standard approach in living kidney donation. Surgeons working in this field must be trained thoroughly and well acquainted with the subtleties of the different LDN techniques and their respective advantages and disadvantages.

    Hand-assisted laparoscopic (HAL) nephrectomy is an increasingly popular surgical modality. Within the last year, three newly designed second-generation hand-assist devices have emerged with the intention to improve efficacy and ease of use. We prospectively evaluated and compared these with each other and with the first-generation devices. A total of 130 urologists performed two HAL nephrectomies in a porcine laboratory using two different hand devices at an American Urological Association-sponsored learning course. Sixty-three urologists utilized the second-generation devices (Gelport, Omniport, LapDisc), while 67 urologists used the first-generation devices (Handport, Intromit, PneumoSleeve). Each surgeon completed a 12-question survey evaluating the devices. Evaluation of the second-generation devices revealed that Gelport was statistically significantly superior in all parameters to the Omniport and in 5 of 10 parameters to the LapDisc. Comparison of the first- and second-generation devices revealed that only the Gelport achieved a significant increase in all ratings. Among the first-generation devices, no device scored better than 8.27 of 10 in any category. Analysis of the second-generation devices demonstrated that the Gelport scored a rating above 8.25 in all parameters with an overall satisfaction score of 8.59. Both the Omniport and the LapDisc attained ratings comparable to those of the first-generation devices. The HAL procedure relies heavily on devices that allow the hand to be introduced into the laparoscopic environment. The Gelport, when evaluated in a porcine model by training laparoscopic urologists, appears to be significantly better than other devices available to date. Further testing with larger cohorts and human clinical trials are required to confirm these findings.

    Mature cystic teratomas are benign neoplasms of germ cell tumors that occur most frequently in gonadal sites. The tumors usually contain 2 or 3 well-differentiated elements of endodermal, ectodermal, and mesodermal origin. Although relatively uncommon, teratomas can be composed of mature tissue originating from only 1 germ cell layer. This is known as a monodermal teratoma. Extragonadal teratomas, especially mesenteric teratomas, are extremely rare. Currently, only 21 cases of mesenteric teratoma have been described in the English literature. Mesenteric teratomas are rarely diagnosed preoperatively because pathological examination is necessary to make a definitive diagnosis. We herein report a rare case of mesenteric monodermal teratoma and review the literature. To the best of our knowledge, this is the first case of mesenteric teratoma treated with hand-assisted laparoscopic surgery. PMID:24680163

    To review our perioperative complications during the first decade of using hand-assisted laparoscopic nephrectomy using a sleeve (HALN). HALN is a minimally invasive procedure first reported by our group in 1997. After institutional review board approval, the charts of the patients who had undergone HALN, hand-assisted laparoscopic partial nephrectomy, or hand-assisted laparoscopic nephroureterectomy from 1997 to 2007, at our institution, were retrospectively reviewed. Standard laparoscopic procedures were not included. The relevant patient characteristics, operative details, American Society of Anesthesiologists score, body mass index, comorbidities, medications, and complications were recorded. A total of 227 consecutive patients had undergone Hand-assisted laparoscopic renal surgery, and all their charts were reviewed. Of these 227, 134 were radical HALN, 37 were nonradical HALN, 42 were hand-assisted laparoscopic partial nephrectomy, and 15 were hand-assisted laparoscopic nephroureterectomy. Complications developed in 59 patients (26%): 8% major and 18% minor. The procedure-specific complication rate was 29% for radical HALN, 27% for nonradical HALN, 33% for hand-assisted laparoscopic nephroureterectomy, and 17% for hand-assisted laparoscopic partial nephrectomy. Complications included blood transfusion in 6%, urinary retention in 4%, ileus in 4%, and wound infection in 4%. From 2003 through 2007 (n = 163), our overall complication rate was 22% (8% major and 13% minor). From 1997 to 2002 (n = 65), the overall complication rate was 38% (P = .02). The American Society of Anesthesiologists score and the use of systemic steroids were associated with the occurrence of perioperative complications. Our results have shown that hand assistance provides a safe, minimally invasive laparoscopic procedure. Our complications rates were comparable to those with other standard and hand-assist series, although the spectrum of complications varied. Hand-assisted laparoscopic

    Previous simulation and porcine experiments aboard the reduced gravity program KC-135 turbojet have demonstrated that microgravity surgery is feasible. Ideally, surgical care in spaceflight will incorporate recent advances in care while remaining easy enough for a crew medical officer (CMO) lacking surgical proficiency or extensive surgical experience to perform. As a minimally invasive surgical technique, hand-assisted laparoscopic surgery (HALS) benefits the patient via smaller incisions, less pain, and faster recovery than traditional open surgery. HALS also helps less experienced laparoscopic surgeons perform laparoscopic surgery. An inexpensive inanimate surgical simulator was constructed to evaluate the usefulness of HALS in microgravity. This simulator was utilized during brief periods of microgravity provided by parabolic flight on the KC-135. The simulator was successfully used by both a physician-astronaut and an experienced laparoscopic surgeon. Task completion included simulated surgery with exploration of the intestines and ligation of the appendix. Simulated HALS was successfully performed in microgravity. HALS effectively contained operative equipment and small amounts of introduced fluids within the simulated abdominal cavity. Astronaut and surgeon experience suggest that HALS could facilitate minimally invasive surgery (MIS) in microgravity. HALS holds promise as a surgical approach in microgravity, particularly as space travel extends beyond low earth orbit. HALS provides the benefits of MIS, facilitates MIS surgery by less surgically proficient or experienced CMOs, and contains equipment and fluid within the operative field. Simulation provides an easy, cost-effective platform to evaluate medical technology for space flight as well as a method to train CMOs on-orbit.

    Single-incision laparoscopic colorectal surgery is an emerging modality. We incorporated this technique as an alternative to hand-assisted laparoscopic surgery. We investigated intraoperative and short-term outcomes following single-incision laparoscopic colectomy compared with hand-assisted laparoscopic colectomy. Between July and November 2009, single-incision colorectal procedures were performed and matched to hand-assisted procedures based on five criteria: gender, age, body mass index, pathology, and type of procedure. Demographic, intraoperative, and postoperative data were assessed. Twenty-four pairs of patients with a mean age of 55.1 years and mean body mass index of 28.5 kg/m(2) were matched. The majority of cases (79.2%) were right hemicolectomies. The ranges of incision length were 2-6 cm (single incision) and 5-11 cm (hand-assisted). Mean operating time was significantly longer for single-incision procedures (143.2 min) compared with hand-assisted procedures (112.8 min), p < 0.0004. There was no significant difference in the groups regarding conversions or intraoperative complications (p < 0.083 and p < 1.0, respectively). Mean length of stay for the single-incision approach (2.7 days) was significantly shorter compared with the hand-assisted approach (3.3 days), p < 0.02. Single-incision laparoscopic colectomy is a safe and feasible alternative to hand-assisted laparoscopic surgery. Although the technique required longer operative time, it resulted in smaller incision size and significantly shorter length of hospitalization.

    Xanthogranulomatous pyelonephritis presenting with nephrocutaneous fistula is a rare condition, and its treatment of choice is nephrectomy. Laparoscopic management has been proved to be challenging in these inflammatory renal conditions. However, there was no previous report in the literature regarding laparoscopic treatment of nephrocutaneous fistula especially after previous operation. In this communication, we report the first case of hand-assisted laparoscopic nephrectomy for xanthogranulomatous pyelonephritis with nephrocutaneous fistula after previous failed flank exploration.

    A successful case of a hand-assisted laparoscopic splenectomy with low-pressure pneumoperitoneum for autoimmune thrombocytopenic purpura in a patient at 23 weeks' gestation is reported. Preoperative splenic arterial embolization was performed on the same day as the operation using painless contour embolic material and super-absorbent polymer microspheres. The abdominal wall retraction method first was applied to avoid the effects of pneumoperitoneum on systemic hemodynamic alterations. However, a sufficient surgical view could not be obtained, as the intra-abdominal organs were elevated because of the enlarged uterus. A surgical view with 4 to 6-mm Hg pneumoperitoneum was available for the hand-assisted splenectomy. The postoperative course was uneventful, and the patient vaginally delivered a healthy infant. A hand-assisted laparoscopic splenectomy with low-pressure pneumoperitoneum after splenic arterial embolization would be feasible for patients with autoimmune thrombocytopenic purpura during a relatively advanced pregnancy.

    To perform a cost comparison of three approaches to partial nephrectomy (PN): Open (OPN), hand-assisted laparoscopic (HALPN), and robot-assisted (RAPN). We retrospectively evaluated cost and clinical data from patients undergoing OPN, HALPN, and RAPN from 2007 to 2010 (n=89). Baseline demographic data, patient comorbidities, R.E.N.A.L. nephrometry score, and perioperative outcomes were assessed. Costs and subcosts from the operating room (OR) and hospital were evaluated using nonparametric statistical analyses. Patient demographics and tumor characteristics were similar between HALPN and RAPN, while OPN patients had more comorbidities and more difficult-to-resect tumors. Thus, HALPN and RAPN were directly compared, while OPNs were excluded from the analysis. No difference was found in overall costs between HALPN and RAPN ($13,560 vs $13,439, P=0.29). OR costs were higher for RAPN ($7276 vs $5708, P=0.0001) because of the higher robotic capital and reusable equipment costs that outweighed higher disposable costs in the HALPN group. OR time-related costs were similar between groups. RAPN patients had a shorter length of stay (LOS), which decreased postoperative hospital costs ($4371 vs $5984, P=0.002). No difference in overall cost was found between RAPN and HALPN. Robot allocation, OR equipment use, and LOS are important determinants of total cost. Further study regarding recovery and quality of life may reveal added benefits to minimally invasive approaches and increase use of nephron-sparing surgery.

    With the increasing use of partial nephrectomy, cases of ipsilateral tumor recurrence will inevitably occur. We aimed to evaluate the efficacy and feasibility of laparoscopic radical nephrectomy (LRN) for a previously operated kidney, through a case-matched comparison with LRN in patients without prior renal surgery. Among 550 patients who underwent hand-assisted or standard LRN at our institution between August 1996 and January 2013, we identified patients who had prior laparoscopic or open surgical renal surgery. Each study patient was matched 1:2 with patients who had not had prior renal surgery. Matching was exact by surgical approach, gender, side of surgery, and American Society of Anesthesiologists score, and closest possible by age and body mass index. LRN was performed in 9 patients (6 hand-assisted and 3 standard) with prior open surgical or laparoscopic renal surgery. There were no conversions to open surgery. Primary surgeon tended to be to attending urologist more often than the trainee in the study compared to the control patients, an indication of increased technical difficulty. Additionally, there were four intraoperative injuries recorded in the study group (44%) and just one such event in the control group (5.6%) (p = 0.0297). Although LRN after prior renal surgery is challenging, requiring the expertise of experienced surgeons and being associated with appreciable rate of intraoperative injuries, these cases can be completed laparoscopically (especially with the selective use of hand-assistance) and are associated with duration of hospitalization and postoperative complication rates similar to those in patients undergoing LRN without prior renal surgery.

    The objective of this study was to evaluate the short-term outcomes of synchronous hand-assisted laparoscopic (HAL) segmental colorectal resections. The surgical options for synchronous colonic pathology include extensive colonic resection with single anastomosis, multiple synchronous segmental resections with multiple anastomoses, or staged resections. Traditionally, multiple open, synchronous, segmental resections have been performed. There is a lack of data on HAL multiple segmental colorectal resections. A retrospective chart review was compiled on all patients who underwent HAL synchronous segmental colorectal resections by all the colorectal surgeons from our Group during the period of 1999 to 2014. Demographics, operative details, and short-term outcomes are reported. During the period, 9 patients underwent HAL synchronous multiple segmental colorectal resections. There were 5 women and 4 men, with median age of 54 (24–83) years and median BMI of 24 (19.8–38.7) kg/m2. Two patients were on long-term corticosteroid therapy. The median operative time was 210 (120–330) minutes and median operative blood loss was 200 (75–300) mLs. The median duration for return of bowel function was 2 days and the median length of stay was 3.5 days. We had 2 minor wound infections. There were no deaths. Synchronous segmental colorectal resections with anastomoses using the hand-assisted laparoscopic technique are safe. Early conversion to open and use of stomas are advisable in challenging cases.

    A 52-year-old man was admitted with an incidentally detected right renal artery aneurysm (RAA). Computed tomographic angiography with three-dimensional reconstruction revealed that the aneurysm was 2.2 cm in diameter and located at the renal hilum. We performed hand-assisted laparoscopic nephrectomy with ex vivo repair of the RAA and auto-transplantation with minimal elongation of Gibson incision. The operation and postoperative course were uneventful. At last follow-up, the patient was alive with a well-functioning auto-transplant. Hand-assisted laparoscopic nephrectomy and auto-transplantation is a useful treatment option for hilar RAA.

    A 60-year-old male was found to have an 8.0 cm left renal mass and associated renal vein thrombus on computed tomography. The thrombus extended 3 mm beyond the right aortic border to within 1.6 cm of the left border of the inferior vena cava. The patient underwent left nephrectomy with renal vein thrombectomy using a hand-assisted laparoscopic approach. The tumor thrombus was "milked" proximally back into left renal vein, which was then divided with an endovascular stapler. Left renal vein thrombi extending to right margin of the aorta can be managed with hand-assisted laparoscopic approach.

    To assess the efficacy of laparoscopic proctosigmoidectomy for cancer treatment, 25 patients who underwent hand-assisted laparoscopic resection during the study period (9/2006 - 7/2012) were matched to 25 straight-laparoscopic and 50 open-surgery cases. The patients who underwent hand-assisted resection had higher rates of preoperative cardiac disease and hypertension than did the straight-laparoscopy and open-surgery groups. Straight-laparoscopic surgery seems to provide faster convalescence compared with open surgery and hand-assisted laparoscopic surgery.

    The purpose of the study was to sterilize renal tuberculous foci in a pretransplantation patient with a laparoscopic hand-assisted approach and to verify the feasibility of bilateral nephrectomy for this indication. This case report is the first description of hand-assisted laparoscopic bilateral nephrectomy for this pathologic condition. The 33-year-old patient had end-stage renal disease from renal tuberculosis. A commercially available hand-assistance device was used through a midline 8-cm supraumbilical incision and with four ports. The procedure was successfully completed. The total operative time was 3 hours and 40 minutes. Estimated blood loss was 250 mL. The postoperative course was uneventful, and clinical follow-up at 3 weeks revealed a successful outcome. Hand-assisted bilateral laparoscopic nephrectomy in patients with chronic renal failure from tuberculosis represents a viable option because it is feasible and effective. The hand-assisted approach increases the safety of the procedure while retaining all the advantages of minimally invasive surgery.

    The visual information obtained in hand-assisted laparoscopic surgery (HALS) and total laparoscopy is based on two-dimensional depth cues. This study was designed to test the hypothesis that intracorporeal hand improves depth perception in HALS. Ten subjects were divided into two groups using HALS or total laparoscopy. The first task was passing a 10-cm thread through four small metallic loops five times; the second was tying 30 square three-throw intracorporeal laparoscopic knots. End points were (1) number of past pointing as an index of movement accuracy and reflection of depth perception, (2) execution time, and (3) knot quality score. The HALS group was significantly faster than total laparoscopy with a median (interquartile range (IQR)) of 117 s (75.5) vs. 179 s (235.5; P = 0.001) for the thread passing task and 97 s (43.3) vs. 130 s (68.3; P < 0.0005) for knot tying. The number of past-pointing events was significantly lower with HALS compared with total laparoscopy with a median (IQR) of 12 (8) vs. 23 (24; P = 0.001) for the thread passing task and 7 (5) vs. 13 (10; P < 0.0005) for knot tying. There was a significant main effect of whether the targeted object was in contact with the other instrument in knot tying task when past-pointing occurred (P = 0.031). No difference in a knot quality score was found between the HALS and total laparoscopy. The accuracy of instrument movement was significantly better in the HALS group compared with total laparoscopy. The study confirmed the hypothesis that intracorporeal hand improves depth perception in HALS. Also, the touch of the assisting instrument with the target object enhances spatial orientation in the laparoscopic operative field. However, further study is needed to test the hypothesis in experts.

    Objective: Hand assist laparoscopic surgery (HALS) is a surgical modality rarely used in benign gynecology. We analyzed nonmalignant pelvic disorders that utilized HALS to see whether there is any benefit over standard laparotomy. Methods: A case control chart review identified patients who underwent HALS for a variety of benign gynecological conditions from 2004 through 2007. Cases were then compared with a control group of all the patients who underwent similar procedures for the same diagnosis via laparotomy (ELAP) in our center within the same time period. The groups were comparable with respect to age, BMI, and surgical indication. Results: Twenty-nine patients were analyzed: 12 cases (HALS) and 17 controls (ELAP). Each group was broken up into 2 subsets: Group A, older patients who underwent surgery for pelvic organ prolapse or diverticulitis with adnexectomy and Group B, younger patients who underwent surgery for pelvic pain, endometriosis, or both. Hospital stay in Group B was statistically lower in the HALS cases vs. the ELAP controls, (2.9 vs. 5.4 days, P=0.04). All HALS and ELAP patients were then analyzed for overall trends. HALS cases had shorter hospitalization than ELAP controls had (3.3 vs 4.5 days, P=0.035). Estimated blood loss was also less overall in the HALS cases vs. the ELAP controls (175 vs 355.9 mL, P=0.021). There were 2 adverse outcomes reported in Group A of the HALS cases. These 2 patients experienced postoperative hernias though the hand-assist port-site incision. Conclusion: Compared with laparotomy, overall, HALS offers the advantage of decreased hospitalization and decreased intraoperative blood loss. Postoperative hernias through the HA port site may be a potential problem with this technique. PMID:20529531

    Robot-assisted laparoscopic partial nephrectomy (RALPN) and laparoscopic partial nephrectomy (LPN) have become standard for the surgical management of small renal masses (SRMs). However, no studies have evaluated the short-term outcomes or cost of RALPN as compared with hand-assisted laparoscopic partial nephrectomy (HALPN) in a standardized fashion. A retrospective review of all patients who underwent HALPN or RALPN from 2006 to 2010 were assessed for patient age, body mass index (BMI), American Society of Anesthesiologists (ASA) score, radiographic tumor size, nephrometry (radius, endo/exophytic, nearness to collecting system, anterior/posterior, lines of polarity [RENAL]) scores, operative and room times, hospital length of stay (LOS), estimated blood loss (EBL), requirement of hilar vessel clamping, warm ischemia time (WIT), pre- and postprocedural creatinine and hemoglobin levels, and complications. Total costs of the procedures were estimated based on operating room component (operative staff time, anesthesia, and supply) and hospital stay cost (room and board, pharmacy). A robotic premium cost, estimated based on the yearly overall cost of the da Vinci S surgical system divided by the annual number of cases, was included in the RALPN cost. Cost figures were obtained from hospital administration and applied to the mean HALPN and RALPN patient. Forty-seven patients underwent HALPN since 2006 and 21 patients underwent RALPN since 2008. ASA, BMI, EBL, tumor size, nephrometry score, positive margin rate, change in creatinine, change in hemoglobin, morphine equivalents used, and complication rate were all similar in both groups (p>0.05). Room time and operative time were significantly shorter for the HALPN cohort (p=0.001) whereas LOS was significantly shorter in the RALPN cohort (p=0.019). Despite the shorter LOS, RALPN was associated with a $1165 increased cost, mainly due to increased operating room time and premium cost of the robot. While early in our

    Purpose To demonstrate the feasibility, safety, and technical strategies of hand-assisted laparoscopic complete mesocolic excision (HAL-CME) and to compare oncological outcomes between HAL-CME and the open approach (O-CME) for right colon cancers. Methods Patients who were scheduled to undergo a right hemicolectomy were divided into HAL-CME and O-CME groups. Measured outcomes included demographic variables, perioperative parameters, and follow-up data. Demographic variables included age, sex distribution, body mass index (BMI), American Society of Anesthesiologists (ASA) physical status classification, previous abdominal surgery, tumor localization, and potential comorbidities. Perioperative parameters included incision length, operative time, blood loss, conversion rate, postoperative pain score, postoperative first passage of flatus, duration of hospital stay, total cost, number of lymph nodes retrieved, TNM classification, and postoperative complications. Follow-up data included follow-up time, use of chemotherapy, local recurrence rate, distant metastasis rate, and short-term survival rate. Results In total, 150 patients (HAL-CME, 78; O-CME, 72) were included. The groups were similar in age, sex distribution, BMI, ASA classification, history of previous abdominal surgeries, tumor localization, and potential comorbidities. Patients in the HAL-CME group had shorter incision lengths, longer operative times, less operative blood loss, lower pain scores, earlier first passage of flatus, shorter hospital stay, higher total costs, similar numbers of lymph nodes retrieved, similar TNM classifications, and a comparable incidence of postoperative complications. The 2 groups were also similar in local recurrence rate, distant metastasis rate, and short-term survival rate. Conclusion The results demonstrate that the HAL-CME procedure is a safe, valid, and feasible surgical method for right hemicolon cancers. PMID:28203556

    Laparoscopic surgery is associated with well-known benefits, one of which is earlier return of bowel function. Since the laparoscopic approach to colon resections was introduced in the early 1990s, it has become the standard of care. Hand-assisted laparoscopic surgery (HALS) is a surgical approach in which dissection is facilitated by the surgeon's hand within the abdominal cavity during laparoscopy. The purpose of this study was to compare the incidence of postoperative ileus and the need for nasogastric tube (NGT) decompression in patients undergoing elective colon resections. Following institutional review board approval, we performed a retrospective review of a prospectively collected database. Included were patients who underwent elective left-sided large bowel resections between 2009 and 2012. Exclusion criteria were urgent operation, stoma creation, ASA IV classification, NGT left in place at the end of surgery, and postoperative anastomotic leakage. Patients were divided into three groups: laparoscopic surgery, HALS, and open surgery. We evaluated the incidence of postoperative ileus and the use of nasogastric decompression in each group. A total of 243 patients were included in this study; 73 patients underwent open surgery, 89 patients underwent HALS, and 81 patients underwent laparoscopic surgery. The proportion of patients who needed postoperative nasogastric decompression was significantly reduced in patients undergoing laparoscopic surgery (3.7%) or HALS (4.5%) compared with those who underwent open resection (17.8%). The time from surgery to first flatus and first bowel movement, the time to tolerate solid diet, and the total length of postoperative hospital stay also were all significantly reduced in the laparoscopic and HALS groups compared with the open surgery group. There were no significant differences in any of these measures between the laparoscopic group and the hand-assisted group. Like laparoscopy, HALS is associated with less

    Objective: The laparoscopic approach is increasingly used for surgical treatment of colorectal cancer. The aim of this study was to assess the efficacy of laparoscopic proctosigmoidectomy for cancer treatment by comparing postoperative outcomes among three groups: hand-assisted laparoscopic resection, conventional straight-laparoscopic resection, and open resection. Methods: Patients who underwent hand-assisted proctosigmoidectomy because of rectal or sigmoid adenocarcinoma between September 2006 and July 2012 were case-matched to their straight-laparoscopy and open-surgery counterparts. Tumor location, tumor stage, resection type, and year of surgery were the matching criteria. Patients who had an abdominoperineal resection were excluded from the study. Results: Twenty-five patients underwent hand-assisted laparoscopic resection during the study period and were matched to 25 straight-laparoscopic and 50 open-surgery cases. The patients who underwent hand-assisted resection had higher rates of preoperative cardiac disease and hypertension than did the straight-laparoscopy and open-surgery groups (76% vs 64% vs 26%; p < 0.0001 and 72% vs 68% vs 42%; p = 0.02, respectively). A history of previous abdominal operations was highest in the straight-laparoscopy group (p = 0.01). The mean estimated blood loss was lowest in the straight-laparoscopy group (p = 0.01). The straight-laparoscopy group had the shortest median length of postoperative hospital stay (p = 0.04). Disease-free survival and overall survival was similar among the groups. Conclusions: Although both hand-assisted and straight-laparoscopic proctosigmoidectomy appear to be as safe and effective as open surgery in short-term and midterm outcomes, straight-laparoscopic surgery seems to provide faster convalescence compared with open surgery and hand-assisted laparoscopic surgery.

    Background Multiple techniques for splenectomy are now employed and include open, laparoscopic and hand-assisted laparoscopic splenectomy (HALS). Concerns regarding a purely laparoscopic splenectomy for massive splenomegaly (> 20 cm) arise from potentially longer operative times, higher conversion rates and increased blood loss. The HALS technique offers the potential advantages of laparoscopy, with the added safety of having the surgeon’s hand in the abdomen during the operation. In this study, we compared the HALS technique to standard open splenectomy for the management of massive splenomegaly. Methods We reviewed all splenectomies performed at 5 hospitals in the greater Vancouver area between 1988 and 2007 for multiple demographic and outcome measures. Open splenectomies were compared with HALS procedures for spleens larger than 20 cm. Splenectomy reports without data on spleen size were excluded from the analysis. We performed Student t tests and Pearson χ2 statistical analyses. Results A total of 217 splenectomies were analyzed. Of these, 39 splenectomies were performed for spleens larger than 20 cm. We compared the open splenectomy group (19 patients) with the HALS group (20 patients). There was a 5% conversion rate in the HALS group. Estimated blood loss (375 mL v. 935 mL, p = 0.08) and the mean (and standard deviation [SD]) transfusion rates (0.0 [SD 0.0] units v. 0.8 [SD 1.7] units, p = 0.06) were lower in the HALS group. Length of stay in hospital was significantly shorter in the HALS group (4.2 v. 8.9 d, p = 0.001). Complication rates were similar in both groups. Conclusion Hand-assisted laparoscopic splenectomy is a safe and effective technique for the management of spleens larger than 20 cm. The technique results in shorter hospital stays, and it is a good alternative to open splenectomy when treating patients with massive splenomegaly. PMID:21443834

    To assess the feasibility and safety of radiofrequency ablation (RFA) with hand-assisted laparoscopic surgery (HALS) for hepatocellular carcinoma (HCC) in the caudate lobe with severe liver dysfunction. HCC in the caudate lobe remains one of the most difficult locations where various treatments tend to pose problems regarding the optimal surgical approach. The technique of HALS has thus been proposed as a useful method for performing a safe RFA therapy. For this study, we assessed the feasibility and safety of RFA with HALS for the treatment of HCC in the caudate lobe with liver dysfunction. Between July 1999 and February 2005, 5 patients who suffered from HCC in the caudate lobe were indicated for RFA. The percutaneous puncture was difficult and all patients have severe liver dysfunction with viral chronic hepatitis. Therefore, RFA was assisted by an inserted hand through a minimal skin incision under laparoscopic inspection. An intraoperative endoscopic ultrasound examination was performed before RFA to determine the tumor region. The hand-assisted minimal dissection around the caudate lobe was required to detect tumor and avoid injuries of other tissues. RFA for HCC was performed using a cooled-tip (Radionics Inc, Burligton, MA) connected to a RF generator under the programmed cyclic impedance. The surgical procedures consisted of 5 RFA to tumors in the caudate lobe with HALS, which was performed safely, and a postoperative computed tomography scan revealed a sufficient ablation in all patients. There was no operative mortality but 1 patient had minor bile leakage, which was treated conservatively, and all patients recovered and thus were eventually discharged. One patient had local recurrence after 3 months, 3 patients had tumor recurrences in another segment after 6 months. At a mean follow-up 32.2 months, all patients were still alive. RFA with HALS is considered to be a safe and feasible technique for HCC in the caudate lobe with liver dysfunction.

    Laparoscopic liver resection has been established as a safe and feasible treatment option. Surgical approaches include pure laparoscopy, hand-assisted laparoscopy (HALS), and the hybrid technique. The role of these three approaches, and their superiority over open laparotomy, is not yet known. A literature review was performed using specific search phrases, relating to hand-assisted or hybrid approaches to laparoscopic liver resection. Surgical results from 18 case series (HALS, nine series; hybrid technique, nine series), each with ≥ 10 patients, were analyzed. Results indicated that HALS was associated with a mean operative time of 82-264.5 min, an estimated blood loss of 82-300 mL, and a complication rate of 3.8-27.1%. Analysis of series involving the hybrid technique indicated a mean operative time of 111-366.5 min, an estimated blood loss of 93-936 mL, and a complication rate of 3.4-23.5%. In conclusion, there is insufficient evidence to conclude that any single approach is superior to the others, although HALS and the hybrid technique are useful when dealing with difficulties associated with pure laparoscopy. Conversely, the need for these two methods, which can function as a bridge to pure laparoscopic liver resection, may be overcome with appropriate training.

    To determine the feasibility and long-term outcomes of hand-assisted laparoscopic nephroureterectomy (HALNU) compared with open nephroureterectomy (ONU) in the management of pT(3)N0 upper urinary tract urothelial carcinoma (UUT-UC). Between January 1994 and December 2005, 21 patients who underwent HALNU for stage pT(3)N0 UTT-UC were matched and compared with 31 patients who underwent ONU. The oncologic out-comes, including bladder recurrence, recurrence-free survival, cancer-specific survival, and overall survival, were statistically analyzed. The median follow-up period in the HALNU group was 72 months (range 33-111 months) and 115 months in the ONU group (range 24-161 months). Patient age, sex, body mass index, tumor size, specimen weight, and American Society of Anesthesiologists classification showed no significant difference between the two groups. The HALNU group had statistically less blood loss than the ONU group (113 mL versus 487 mL; P = 0.02). The average hospital stay and doses of narcotic analgesics were significantly less in the HALNU group than the ONU group. The complication and bladder recurrence rates were similar between the two groups. The 5-year recurrence-free survival, cancer-specific survival, and overall survival were also comparable in both groups. HALNU is a safe and efficacious procedure with comparable long-term oncologic outcomes in comparison with ONU in treating patients with locally advanced pT(3)N0UUT-UC.

    Robotic-assisted laparoscopic surgery is an emerging modality in the field of minimally invasive colorectal surgery. However, there is a dearth of data comparing outcomes with other minimally invasive techniques. We present a 3-arm (conventional, hand-assisted, and robotic) matched-case analysis of intraoperative and short-term outcomes in patients undergoing minimally invasive colorectal procedures. Between August 2008 and October 2009, 70 robotic cases of the rectum and rectosigmoid were performed. Thirty of these were organized into triplets with conventional and hand-assisted cases based on the following 6 matching criteria: 1) surgeon; 2) sex; 3) body mass index; 4) operative procedure; 5) pathology; and 6) history of neoadjuvant therapy in malignant cases. Demographics, intraoperative parameters, and postoperative outcomes were assessed. Pathological outcomes were analyzed in malignant cases. Data were stratified by postoperative diagnosis and operative procedure. There was no significant difference in intraoperative complications, estimated blood loss (126.1 ± 98.5 mL overall), or postoperative morbidity and mortality among the groups. Robotic technique required longer operative time compared with conventional laparoscopic (P < .01) and hand-assisted (P < .001) techniques; however, this difference was not maintained in cases with low pelvic anastomoses. The overall mean length of stay was 3.3 ± 1.8 days with no significant difference between the groups. Pathological analysis of malignant cases revealed a median lymph node extraction of 17 with no significant difference among the 3 modalities. In this 3-arm case-matched series, the robotic approach results in short-term outcomes comparable to conventional and hand-assisted laparoscopic approaches for benign and malignant diseases of the rectum and rectosigmoid. With 3-dimensional visualization, additional freedom of motion, and improved ergonomics, this enabling technology may play an important role when

    To evaluate the stage- and grade-specific survival rate in patients with upper urinary tract (UUT) transitional cell carcinoma (TCC) after open (ONU) or hand-assisted laparoscopic nephroureterectomy (LNU) with bladder-cuff excision. From January 1998 to April 2005, 143 patients with UUT-TCC were treated with either ONU or LNU and enrolled in the study. The peri-operative data were collected by retrospective chart review. The recurrence, metastasis and survival rate were calculated. The 5-year disease-specific survival of patients with pT1 disease was 88.1% after ONU and 92.0% after LNU (P = 0.745); the respective values for patients with pT2 were 11/17 and 12/15 (P = 0.874), and for pT3 were six/11 and 12/15 (P = 0.476). The incidence of bladder recurrence within 2 years after surgery was 24.7% for ONU and 19.7% for LNU (P = 0.475). The results were similar after ONU or LNU with bladder-cuff excision; bladder-cuff excision using a hand-assisted device is effective and serves as a treatment option for patients with UUT-TCC.

  1. Is laparoscopic live donor hepatectomy justified ethically?

    2016-04-01

    Live donor liver transplant (LDLT) was first reported in the 1990s and quickly raised ethical considerations, mainly related to the risk brought to the donor. The question of donor safety was even more accurate with the occurrence of laparoscopy, a technique which could allegedly increase the risk of severe intraoperative complications. Besides the questions of justice and autonomy, donor safety remains the main ethical debate of LDLT. Considering the lack of comparative assessment of postoperative outcomes, the Jury of the last Consensus meeting held in Japan in 2014 called for the creation of international registries to help to determine the benefit/risk ratio of laparoscopic donor hepatectomy. Since randomized studies are very unlikely to occur, benchmarking comparisons, between liver and kidney donors for instance, may also help to define standard practice. At last, donors' points of view should also be taken into account in the evaluation of those innovative procedures. © 2016 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

    Epiphrenic esophageal diverticulum is a rare condition that is often associated with a concomitant esophageal motor disorder. Some patients have the chief complaints of swallowing difficulty and gastroesophageal reflux; traditionally, such diverticula have been resected via right thoracotomy. Here, we describe a case with huge multiple epiphrenic diverticula with motility disorder, which were successfully resected using a video-assisted thoracic and laparoscopic procedure. A 63-year-old man was admitted due to dysphagia, heartburn, and vomiting. An esophagogram demonstrated an S-shaped lower esophagus with multiple epiphrenic diverticula (75 × 55 mm and 30 × 30 mm) and obstruction by the lower esophageal sphincter (LES). Esophageal manometry showed normal peristaltic contractions in the esophageal body, whereas the LES pressure was high (98.6 mmHg). The pressure vector volume of LES was 23,972 mmHg(2) cm. Based on these findings, we diagnosed huge multiple epiphrenic diverticula with a hypertensive lower esophageal sphincter and judged that resection might be required. We performed lower esophagectomy with gastric conduit reconstruction using a video-assisted thoracic and hand-assisted laparoscopic procedure. The postoperative course was uneventful, and the esophagogram demonstrated good passage, with no leakage, stenosis, or diverticula. The most common causes of mid-esophageal and epiphrenic diverticula are motility disorders of the esophageal body; appropriate treatment should be considered based on the morphological and motility findings.

    A 37-year-old man was referred for massive splenomegaly. In November 2005, he was diagnosed with non-Hodgkin's B-cell lymphoma in the setting of splenomegaly and thrombocytopenia. His laboratory results showed a coagulopathy owing to lupus anticoagulant. A computed tomography scan showed a 36 x 26 x 11 cm spleen and a prominent and sinuous splenic artery. The authors performed a laparoscopic splenectomy with an initial ligation of the splenic artery. The patient tolerated the procedure well and was discharged home on the fourth postoperative day in stable condition. Discussed in this paper is the safety and feasibility of the minimally invasive approach in massive splenomegaly.

    To report the surgical outcome of retroperitoneoscopic hand-assisted laparoscopic nephroureterectomy (LNU) with bladder cuff excision for upper urinary tract transitional cell carcinoma (TCC), and to compare the outcome with that of the open procedure (ONU). From January 1998 to January 2003, 145 patients with upper urinary tract TCC were enrolled in the study; 87 had ONU and 58 retroperitoneoscopic hand-assisted LNU. The specimens were reviewed by experienced pathologists to confirm the pathological stage. Operative duration, intraoperative blood loss, bowel recovery, analgesic use, hospital stay and time to convalescence were compared for both groups. The Mann-Whitney U-test and Fisher's exact test were used for statistical analysis. RESULTS The mean follow-up for ONU and LNU was 35.1 and 16.0 months, the mean operative duration 230.2 and 259.1 min (P = 0.006), the mean blood loss 747.3 and 408.9 mL (P < 0.001), the mean duration of Foley catheterization 6.8 and 5.1 days (P < 0.001), and the hospital stay 12.6 and 9.3 days (P < 0.001). The bladder recurrence rate 2 years after surgery was 9.1% for ONU and 8.6% for LNU (P = 0.23); the local recurrence rate during the follow-up was 3.4% and none, respectively (P = 0.35). Although LNU took longer than ONU the intraoperative bleeding and hospital stay were better than for ONU. Both procedures have statistically comparable bladder recurrence and local recurrence rates.

    This is a case of impalement injury with delayed presentation. A 60-year-old man experienced a traumatic injury after a fall on top of a broken picture frame, which caused a small laceration to his left upper abdominal wall. Sixteen months after the injury, he developed a tender left abdominal wall and lower abdominal cramping pain. Colonoscopy identified a shard of glass in the left colon. The glass presumably impaled his abdominal wall as a result of his previous traumatic injury and migrated to the left colon. Laparoscopic surgery was used to safely and efficiently remove the impaled glass shard and affected portion of colon. Such a case has never been reported.

    Perioperative intravenous (IV) infusion of lidocaine has been shown to decrease post-operative pain, shorten time to return of bowel function, and reduce the length of hospital stay. This randomized, prospective, double-blinded, placebo-controlled clinical trial evaluated the impact of IV lidocaine on the quality of post-operative analgesia and other outcomes after hand-assisted laparoscopic colon surgery. Sixty four patients with colon cancer scheduled for elective colon resection were involved in this study. Patients were randomized to receive either lidocaine infusion [lidocaine group (LG)] or normal 0.9 % saline infusion [placebo group (PG)] for a period of 24 h. Anaesthetic and surgical techniques were standardized. Twenty-four-hour post-operative analgesia in the recovery area was maintained by continuous infusion of 0.1 μg/kg/h fentanyl. The primary outcome of the study was post-operative pain control. Pain was assessed using visual analogue scale (VAS) scores at 2, 4, 8, 12, and 24 h after surgery. Patients with a VAS score >3 were treated with ketorolac 30 mg as needed. Secondary outcomes included time to resumption of bowel function and length of hospital stay. Data in the two groups were compared using the two-tailed Student's t test. All statistical tests were two-tailed at a significance level of 0.05. Demographic characteristics and clinical features of both groups were similar. Intensity of pain at rest in LG compared with PG was significantly lower during the first 24 h post-operatively. LG patients reported significantly less pain during movements at 2-, 12-, and 24-h post-surgery than PG patients. The study showed that ketorolac consumption was significantly higher in PG: mean ketorolac consumption in LG was 43.77 ± 13.86 mg and in PG 51.67 ± 13.16 mg (p = 0.047). Compared with placebo, lidocaine infusion produced a 32 % reduction in time to the first drink (Cohen's d = 3.85), 16 % reduction in time to the first full diet

    Optimizing a living kidney donation program is important to guarantee a high grade of acceptance among potential donors. Hand-assisted retroperitoneoscopic donor nephrectomy (HARP) is an alternative to the open anterior approach (AA) technique. Problems associated to the learning curve could hinder a transition. 3D display technique seems to ease minimally invasive surgery. Aim of this study was to evaluate the learning curve during the transition from AA to HARP and the influence of the 3D display system on the established technique. Observational study (n = 207) during transition to HARP and introduction of 3D display technique. Operation time (OT), warm ischemia time (WIT) and blood loss (BL) of HARP decreased during transition. Pairwise group comparison for OT showed a significant learning effect for the first 30 out of 50 HARPs without influence on graft function. Between AA and HARP no significant difference in OT (133 ± 24 vs. 127 ± 19 min, p = 0.25) but for WIT (23 ± 28 vs. 126 ± 40 s, p < 0.005) and BL (328 ± 207 vs. 54 ± 35 ml, p < 0.005) was seen. There was neither a significant difference in donors' nor recipients' eGFR. OT (98 ± 16 vs. 106 ± 19 min, p = 0.036) and WIT (97 ± 37 vs. 120 ± 57 s, p = 0.023) were significantly shorter for the 3D technique compared to 2D. A transition to HARP is possible without additional risk for the donor or loss of quality for the recipient. The learning curve for HARP is steep and short. The introduction of 3D display technique after transition facilitates the surgical preparation and could further help to optimize HARP.

    We compared long-term outcomes of LDKT in pediatric recipients following either laparoscopic (LDN) or ODN. In our retrospective single-center study, we compared 38 pediatric LDKT recipients of a laparoscopically procured kidney with a historic ODN group comprising 17 pediatric recipients. In our center, the first pure laparoscopic non-hand-assisted LDN for a pediatric LDKT recipient was performed in June 2001. Demographic data of donors and recipients were comparable between groups. Mean follow-up was 64 months in the LDN group and 137 months in the ODN group. Patient survival was comparable between groups. Graft survival at one and five yr was 97% (LDN) vs. 94% (ODN) and 91% (LDN) vs. 88% (ODN; p = n.s.), respectively. Serum creatinine at one and five yr was 1.16 ± 0.47 mg/dL (LDN) vs. 1.02 ± 0.38 mg/dL (ODN) and 1.38 ± 0.5 mg/dL (LDN) vs. 1.20 ± 0.41 mg/dL (ODN), respectively. The type and frequency of surgical complications did not differ between groups. DGF and acute rejection rates were similar between groups. In the ODN group, a higher proportion of right donor kidneys was used. In the ODN group, all kidneys had singular arteries, whereas in the LDN group five kidneys had multiple arteries. Arterial multiplicity was associated with a higher incidence of DGF. In our experience, LDN does not compromise long-term graft outcomes in pediatric LDKT recipients. Arterial multiplicity of the donor kidney may be a risk factor for impaired early graft function in the pediatric population.

    Effects of laparoscopic donor nephrectomy (LDN) on graft function, especially early post-transplant, have been controversial. To assess and compare early and late graft function in kidneys procured by open and laparoscopic methods, a retrospective observational study was carried out on 37 recipients-donors who underwent LDN after introduction of this technique in February 2007 at our center, a tertiary care nephrology referral center. Demographic, immunological and intraoperative variables as well as immunosuppressive protocols and number of human leukocyte antigen (HLA) mismatches were noted. Early graft function was assessed by serum creatinine on Days two, five, seven, 14 and 28 and at the time of discharge. Serum creatinine values at three months and at one year post-transplant were considered as the surrogates of late graft function. Data obtained were compared with the data from 33 randomly selected kidney transplants performed after January 2000 by the same surgical team, in whom open donor nephrectomy was used. Pearson's chi square test, Student's t test and Mann-Whitney U test were used for statistical analysis. Early graft function (serum creatinine on Day five 2.15 mg/dL vs 1.49 mg/dL, P = 0.027) was poorer in the LDN group. Late graft function as assessed by serum creatinine at three months (1.45 mg/dL vs 1.31 mg/dL, P = 0.335) and one year (1.56 mg/dL vs 1.34 mg/dL, P = 0.275) was equivalent in the two groups. Episodes of early acute graft dysfunction due to acute tubular necrosis were significantly higher in the LDN group (37.8% vs 12.1%, Z score 2.457, P = 0.014). Warm ischemia time was significantly prolonged in the LDN group (255 s vs 132.5 s, P = 0.002). LDN is associated with slower recovery of graft function and higher incidence of early acute graft dysfunction due to acute tubular necrosis. Late graft function at one year is however comparable.

    Laparoscopic donor nephrectomy (LDN) can be performed via either transperitoneal or retroperitoneal approach. Very few studies have been carried out till now, comparing immunologic and inflammatory responses in donors after these two approaches. This is a prospective observational study. Selection of approach was decided by the operating surgeon. All patients underwent peripheral venous blood sampling preoperatively and 24 h postoperatively for the measurement of C-reactive protein (CRP), interleukein-6 (IL-6), total leukocyte count (TLC), blood urea nitrogen (BUN), and serum creatinine (SCr). Operative time, warm ischemia time, hospital stay, requirement of analgesia, and complications were also recorded. From February 2013 to January 2015, we performed 54 LDNs (38 transperitoneal and 16 retroperitoneal). There were 49 females and five males. Mean operative time was not significantly different in these two approaches, but warm ischemia time was significantly less in the retroperitoneal laparoscopic donor nephrectomy (RLN) group. Postoperative inflammatory markers' (IL-6, CRP, and TLC) levels, BUN, and SCr rise in both of these approaches, but there was no significant difference observed between these two approaches. RLN is a safe and effective approach to preserve a longer right renal vein. It combines the benefit of both hand assistance and retroperitoneal approach. Warm ischemic time is significantly less in RLN group.

    Renal transplantation is an effective treatment for patients with end-stage renal disease. Unfortunately, the number of patients waiting for transplantation greatly exceeds the number of suitable organs. Use of live kidney donors can increase the donor pool. Historically, donor nephrectomy was performed as an open technique. Its associated prolonged convalescence and long-term morbidity was likely a disincentive to donate. Laparoscopic donor nephrectomy, however, has been shown to have fewer long-term complications without compromising graft function. Since its inception, there has been an increase in the number of live donor renal transplantations performed.

    To analyze the outcomes of j-pouch and side-to-end anastomosis in rectal cancer patients treated with laparoscopic hand-assisted low anterior resection. Prospective trial on cases randomized to have a colonic j-pouch or a side-to-end anastomosis after low anterior resection. Demographics, characteristics of disease and treatment, perioperative results, and functional outcomes and life quality were compared between the groups. Seventy four patients were randomized. Reservoir creation was withdrawn in 17 (23%) patients, mostly related to reach problem (n = 11, 64.7%). Anastomotic leakage rate was significantly higher in j-pouch group (8 [27.6%] vs. 0, p = 0.004). Stoma closure could not be achieved in 16 (28.1%) patients. Life quality and functional outcomes, measured 4, 8 and 12 months after the stoma reversal, were similar. Colonic j-pouch and side-to-end anastomosis are similar regarding perioperative measures including operation time, rates of postoperative complications, reoperation and 30-day mortality, and hospitalization period except anastomotic leak rate, which is higher in j-pouch group. Postoperative aspects are not different in patients receiving either technique including functional outcomes and life quality for the first year after stoma closure. In our opinion, both techniques may be preferred during the daily practice while performing laparoscopic surgery; but surgeons may be aware of a possibly higher anastomotic leak rate in case of a j-pouch.

Our center initiated such a trial in January 2011, following subjects randomized to LESS-DN vs. LDN from surgery through 5 years post-donation. Subjects complete recovery/satisfaction questionnaires at 2, 6, and 12 months post-donation; transplant recipient outcomes are also recorded. 100 subjects (49 LESS-DN, 51 LDN) underwent surgery; donor demographics were similar between groups, and included a predominance of female, living unrelated donors, mean age of 47 years who underwent left donor nephrectomy. Operative parameters (overall time, time to extraction, warm ischemia time, blood loss) were similar between groups. Conversion to hand-assist laparoscopy was required in 3 LESS-DN (6.1%) vs. 2 LDN (3.9%; P=0.67). Questionnaires revealed 97.2% of LESS-DN vs. 79.5% of LDN (P=0.03) were 100% recovered by two months after donation. No significant difference was seen in satisfaction scores between the groups. Recipient outcomes were similar between groups. Our randomized trial comparing LESS donor nephrectomy to LDN confirms that LESS-DN offers a safe alternative to conventional LDN in terms of intra- and post-operative complications. LDN and LESS-DN offer similar recovery and satisfaction after donation. PMID:24934732

    Despite the increasing adoption of laparoscopic donor nephrectomy, no study has examined donor perceptions following this procedure. In particular, it has been tacitly assumed that a less invasive procedure might in itself provide a more satisfactory donor experience. The present study reviews the experience of donors undergoing laparoscopic nephrectomy, and examines the extent to which contemporary management practice addresses issues relevant to consumerism. Forty-two donors participated in a structured telephone interview, and 33 (79%) returned a written questionnaire. Coming through the survey was a strong sense of commitment to donation, and most respondents were satisfied with the experience. The main criticisms related to hotel services, the duration of the preoperative investigations, the perceived quality of nursing care on the general wards, medical communication and the duration of postoperative follow up. The self-reported time to meet recovery goals was extremely broad. Considering the nature of criticisms offered by the respondents, it is concluded that the expectations of donors as health-care consumers will only be met through modification of existing protocols.

    Advances in minimally invasive surgery for live kidney donors have led to the development of laparoendoscopic single site donor nephrectomy (LESS-DN). At present, laparoscopic donor nephrectomy is the technique of choice for donor nephrectomy globally. Compared with open surgical approaches, laparoscopic donor nephrectomy is associated with decreased morbidity, faster recovery times and return to normal activity, and shorter hospital stays. LESS-DN differs from standard laparoscopic donor nephrectomy; LESS-DN requires a single incision through which the procedure is performed and donor kidney is removed. Previous studies have hypothesised that LESS-DN may provide additional benefits for kidney donors and stimulate increased donor rates. This review looked at the benefits and harms of LESS-DN compared with standard laparoscopic nephrectomy for live kidney donors. We searched the Cochrane Kidney and Transplant's Specialised Register to 28 January 2016 through contact with the Information Specialist using search terms relevant to this review. We included randomised controlled trials (RCTs) that compared LESS-DN with laparoscopic donor nephrectomy in adults. Three authors independently assessed studies for eligibility and conducted risk of bias evaluation. Summary estimates of effect were obtained using a random-effects model and results were expressed as risk ratios (RR) or risk difference (RD) and their 95% confidence intervals (CI) for dichotomous outcomes, and mean difference (MD) and 95% CI for continuous outcomes. We included three studies (179 participants) comparing LESS-DN with laparoscopic donor nephrectomy. There were no significant differences between LESS-DN and laparoscopic donor nephrectomy for mean operative time (2 studies, 79 participants: MD 6.36 min, 95% CI -11.85 to 24.57), intra-operative blood loss (2 studies, 79 participants: MD -8.31 mL, 95% CI -23.70 to 7.09), or complication rates (3 studies, 179 participants: RD 0.05, 95% CI -0.04 to 0

    The learning curve to achieve competency in laparoscopic donor nephrectomy (LDN) is poorly outlined. Online databases were searched for training in LDN. Abstracts and manuscripts were excluded if they did not address introduction of a laparoscopic technique for donor nephrectomy. Relevant manuscripts were reviewed for surgical technique, use of animal models, co-surgeons, surgeon specialty and training, institution type/volume, and assessment of training method. Forty-four met inclusion criteria, with 75% describing the evolution from open to LDN. Eighty-two percent were from academic centers, and 36% were from centers performing <25 donor nephrectomies each year. The learner was an attending surgeon 80% of the time, mostly urologists with prior laparoscopy or open nephrectomy experience. The learning curve, defined by decreased operating time, averaged 35 cases. Improved intra-operative, patient, and recipient outcomes were observed for centers performing ≥50 LDNs annually. The United Network of Organ Sharing requires 15 cases as surgeon or assistant to be certified as the primary LDN surgeon. This falls below the described learning curve for LDN. The assessment of training and competency for LDN is heterogeneous, and objective learner-based metrics could help surgeons and institutions reach a quality standard for performing this operation.

    With refinements in the operative technique, laparoscopic surgery has become the standard practice for liver resection. In the field of living donor liver transplantation, a few centers adopted laparoscopic surgery as an alternative to conventional open donor hepatectomy, and the application of pure laparoscopic donor right hepatectomy has been limited to the donors with simple, favorable biliary anatomy. The candidate donor was a 19-year-old woman with type 3a bile duct variation. After confirming precise cutting points under the guidance of a radiopaque marker rubber band, the bile ducts were divided and the remnant stumps were closed with suture and clipping using Hem-o-lok, respectively. The postoperative course was uneventful and she was satisfactory 6 months after surgery. A laparoscopic donor hepatectomy for the living donor with biliary variation was feasible. Biliary variations are commonly encountered during living donor surgery, and we think that such variations in laparoscopic donor hepatectomy need to be overcome to expand the selection criteria.

    Objective To present our experience with laparoscopic donor nephrectomy (LDN), our complications and management modalities. Material and methods: Fifty-one transperitoneal LDNs performed in our clinic between the years 2011, and 2015, were evaluated retrospectively. Demographic characteristics of the patients, operative and postoperative data and complications were evaluated. Results Nineteen female and 32 male patients with ages ranging from 24 to 65 years underwent left- (n=44), and right-sided (n=7) LDNs. Six patients had two, and one patient three renal arteries. Mean operation time was 115±11 (min–max: 90–150) minutes, and mean warm ischemia time 111±9 (min–max: 90–140 sec) seconds. Mean hospital stay was found to be 2.5±0.5 days. No patient needed to switch to open surgery. In one patient, lumbar vein was ruptured, and hemostatic control was achieved laparoscopically. Postoperative paralytic ileus developed in two patients. Three patients had postoperative atelectasis, and a febrile (38.1°C) episode. Conclusion LDN is a minimally invasive method with advantages of short hospital stay, less analgesic requirement, and better cosmetic results. However it should be performed by surgeons with advanced laparoscopic experience. PMID:28270958

    Background Pneumoperitoneum (PP), as used for laparoscopic procedures, impairs stroke volume, renal blood flow, glomerular filtration rate and urine output. This study investigated whether perioperative fluid management can abolish these negative effects of PP on hemodynamics. Methods Twenty-one patients undergoing laparoscopic donor nephrectomy (LDN) were randomized into three groups: group 1 received overnight infusion and received a bolus of colloid before induction of anesthesia, followed by a bolus just before PP; group 2 received overnight infusion and a colloid bolus before anesthesia; group 3 served as controls and received only infusion during operation. All three groups received the same total amount of crystalloids and colloids until nephrectomy. Data analysis of the donor included; mean arterial pressure (MAP), stroke volume (SV), left ventricular ejection time (LVETc), perioperative urine output and renal function measured as the creatinine clearance (CrCl) until one-year post-operative. Results SV was significantly higher in group 1 compared to controls for all measurements. In the control group SV significantly decreased after changing from the supine to lateral position whereas there was no change in SV in both pre-hydrated groups. In all groups, MAP decreased after induction of anesthesia, and restored to pre-anesthetic values during PP. CrCl decreased in the control group during PP, but not in the other groups. From two days postoperative, CrCl was comparable between the three study groups. Conclusion Overnight infusion and a bolus of colloid just before PP attenuate hemodynamic compromise from PP.

    Nowadays, laparoscopic donor nephrectomy (LDN) has become the gold standard to procure live donor kidneys. As the relationship between donor and recipient loosens, it becomes of even greater importance to optimize safety and comfort of the surgical procedure. Low-pressure pneumoperitoneum has been shown to reduce pain scores after laparoscopic cholecystectomy. Live kidney donors may also benefit from the use of low pressure during LDN. To evaluate feasibility and efficacy to reduce post-operative pain, we performed a randomized blinded study. Twenty donors were randomly assigned to standard (14 mmHg) or low (7 mmHg) pressure during LDN. One conversion from low to standard pressure was indicated by protocol due to lack of progression. Intention-to-treat analysis showed that low pressure resulted in a significantly longer skin-to-skin time (149 ± 86 vs. 111 ± 19 min), higher urine output during pneumoperitoneum (23 ± 35 vs. 11 ± 20 mL/h), lower cumulative overall pain score after 72 h (9.4 ± 3.2 vs. 13.5 ± 4.5), lower deep intra-abdominal pain score (11 ± 3.3 vs. 7.5 ± 3.1), and a lower cumulative overall referred pain score (1.8 ± 1.9 vs. 4.2 ± 3). Donor serum creatinine levels, complications, and quality of life dimensions were not significantly different. Our data show that low-pressure pneumoperitoneum during LDN is feasible and may contribute to increase live donors' comfort during the early post-operative phase.

    AIM To compare laparoscopic and open living donor nephrectomy, based on the results from a single center during a decade. METHODS This is a retrospective review of all living donor nephrectomies performed at the Massachusetts General Hospital, Harvard Medical School, Boston, between 1/1998 - 12/2009. Overall there were 490 living donors, with 279 undergoing laparoscopic living donor nephrectomy (LLDN) and 211 undergoing open donor nephrectomy (OLDN). Demographic data, operating room time, the effect of the learning curve, the number of conversions from laparoscopic to open surgery, donor preoperative glomerular filtration rate and creatinine (Cr), donor and recipient postoperative Cr, delayed graft function and donor complications were analyzed. Statistical analysis was performed. RESULTS Overall there was no statistically significant difference between the LLDN and the OLDN groups regarding operating time, donor preoperative renal function, donor and recipient postoperative kidney function, delayed graft function or the incidence of major complications. When the last 100 laparoscopic cases were analyzed, there was a statistically significant difference regarding operating time in favor of the LLDN, pointing out the importance of the learning curve. Furthermore, another significant difference between the two groups was the decreased length of stay for the LLDN (2.87 d for LLDN vs 3.6 d for OLDN). CONCLUSION Recognizing the importance of the learning curve, this paper provides evidence that LLDN has a safety profile comparable to OLDN and decreased length of stay for the donor. PMID:28101451

    Abstract Rationale: With the development of laparoscopic technique, the total laparoscopic living donor right hemihepatectomy (LLDRH) procurement surgery has been successfully performed in many liver transplant centers all over the world, and the number of cases is continuing to increase. We report our case of laparoscopic right graft resection with venous outflow reconstruction using cadaveric common iliac artery allograft in our center and review literatures about total LLDRH surgery. Patient concerns and Diagnoses: A 40-year-old male living donor for right hepatectomy was selected after pretransplant evaluation including laboratory tests, liver volume, anatomy of hepatic vein, artery, portal vein, and bile duct. Living donor liver transplantation surgery was approved by Sichuan Provincial Health Department and the ethics committee of the West China Hospital, Sichuan University. Interventions: Hepatic parenchyma transection was performed by ultrasonic scalpel and Cavitron Ultrasonic Surgical Aspirator (CUSA). Right branch of portal vein, right hepatic artery, right hepatic duct, and right hepatic vein were meticulously dissected. The right hepatic duct was ligated and transected 2 mm far from the bifurcation of common hepatic duct, right hepatic artery, and portal vein were also ligated and transected, the right hepatic vein was transected by laparoscopic linear cutting stapler. The gap between short hepatic veins and right hepatic vein was bridged and reconstructed by cadaveric common iliac artery allograft. Outcomes: The operation time was 480 minutes and warm ischemia time was 4 minutes. Blood loss was 300 mL without blood transfusion. The donor was discharged on postoperative day 7 uneventfully without complications. Literatures about laparoscopic living donor right hemihepatectomy are compared and summarized in table. Lessons: The total laparoscopic living donor right hemihepatectomy is technically feasible and safe in some transplant centers which

    Laparoscopic donor nephrectomy (LDN) has been associated with delayed graft function compared with open donor nephrectomy (ODN). We have recently shown that the adverse effect of pneumoperitoneum (PP) on hemodynamics could be prevented by a new fluid regime. The aim of this study was to test the effect of this fluid regime on the kidney function of the donor and recipient after LDN and ODN. We prospectively collected data of 51 donors undergoing ODN and 59 donors undergoing LDN as well as data from the corresponding recipients. All donors and recipients were treated with a standardized anesthesia and fluid regime. This fluid regime consisted of preoperative overnight hydration together with a bolus of colloid administered before induction of anesthesia and before introduction of PP. Follow-up was 2 years. Baseline characteristics of the two groups were comparable. Hemodynamics and urine output until nephrectomy were comparable between both groups. Donor kidney function did not differ after ODN and LDN. Estimated glomerular filtration rate, graft survival, and recipient survival did not differ between open and laparoscopically procured transplants. No adverse effects of the novel fluid regime (eg, pulmonary edema or additional oxygen supply) were observed in the donors. In contrast to our earlier findings, the kidney function of the donor and recipient is comparable between ODN and LDN after introduction of a new fluid regime.

    Renal transplantation is the treatment of choice for end-stage renal disease. Living related kidney donation is the major source of renal grafts due to limited availability of cadaveric kidneys. Open nephrectomy was used to harvest donor kidneys. However, the laparoscopic approach is associated with less postoperative pain and quick recovery. So, most centers now prefer a laparoscopic approach to explant donor kidneys. Laparoscopic approach is technically challenging due to limited operative visibility. Hence, accurate preoperative detection of renal arterial and venous anomalies is imperative to avoid inadvertent vascular injury and bleeding. The preoperative workup of renal donors includes clinical evaluation, laboratory tests, and imaging. Traditionally, the renal donors were evaluated with conventional imaging techniques, which included renal catheter angiography and intravenous urography. However, conventional imaging is invasive, expensive, and less accurate for evaluation of complex renal venous anomalies, small calculi, and diffuse or focal renal parenchymal lesions. The introduction of multidetector row computed tomography (MDCT) revolutionized the CT technology by enabling isotropic resolution with faster scan coverage in a single, short breath-hold. Consequently, MDCT has now replaced conventional imaging for comprehensive imaging of potential living renal donors. MDCT is a minimally invasive technique that can accurately detect urolithiasis, renal arterial and venous anomalies, renal parenchymal lesions, and urinary tract anomalies. Renal vascular anomalies detected by MDCT can help the surgeon in planning donor nephrectomy. MDCT with three-dimensional CT angiography enables accurate preoperative renal vascular mapping. This article reviews the role of MDCT in preoperative evaluation of potential laparoscopic renal donors.

    As Laparoscopic Donor Nephrectomy (LDN) offers several advantages for the donor such as lesser post-operative pain, fewer cosmetic concerns and faster recovery time, there is growing global trend towards LDN as compared to open nephrectomy. Comprehensive pre-LDN donor evaluation includes assessment of renal morphology including pelvi-calyceal and vascular system. Apart from donor selection, evaluation of the regional anatomy allows precise surgical planning. Due to limited visualization during laparoscopic renal harvesting, detailed pre-transplant evaluation of regional anatomy, including the renal venous anatomy is of utmost importance. MDCT is the modality of choice for pre-LDN evaluation of potential renal donors. Apart from appropriate scan protocol and post-processing methods, detailed understanding of surgical techniques is essential for the Radiologist for accurate image interpretation during pre-LDN MDCT evaluation of potential renal donors. This review article describes MDCT evaluation of potential living renal donor, prior to LDN with emphasis on scan protocol, post-processing methods and image interpretation. The article laid special emphasis on surgical perspectives of pre-LDN MDCT evaluation and addresses important points which transplant surgeons want to know.

    We report the case of a 30-year-old male patient undergoing a robotic-assisted laparoscopic left donor nephrectomy, where compression of the left renal vein between the superior mesenteric artery and aorta was noted on magnetic resonance angiography before the operation. The patient was diagnosed with nutcracker phenomenon and was noted to be asymptomatic at that time. This is the first reported case to date of a patient with nutcracker phenomenon who underwent a robotic-assisted laparoscopic donor nephrectomy. This article also reviews the current literature on nutcracker phenomenon and nutcracker syndrome.

    Systemic heparin administration during laparoscopic donor nephrectomy (LDN) may prevent microvascular thrombus formation following warm ischemia. We herein present our experience with and without systemic heparinization during LDN. We retrospectively reviewed donor complications and graft outcomes in 119 consecutive live donor kidney transplantations between January 2005 and December 2009. Systemic heparin was administered to the first 65 donors. LDN was carried out by 2 surgeons using a pure laparoscopic technique. Total operating time for LDN was significantly longer in the heparin group (202 vs. 157 min). The incidence of renal artery multiplicity was significantly higher in the heparin group. Mean warm ischemia time was 160 s, and mean hospital stay was 5 days with no differences between groups. Postoperative hemorrhage occurred in 3 donors with systemic heparinization and in 1 without heparinization. Two donors received blood transfusions, and 2 underwent laparoscopic reexploration. Three grafts were lost in the heparin group and 1 in the non-heparin group. Graft loss was due to early vascular thrombosis (n = 3) and due to acute rejection (n = 1). Overall, 1-year graft survival was 96.6%, and 1-year serum creatinine was 1.41 mg/dl (P = n. s. between groups). Abandoning systemic donor heparinization in LDN with short warm ischemia has a low complication rate without adverse effects on short- and long-term graft outcomes.

    Controlled ligation and division of the renal hilum are critical steps during laparoscopic living donor nephrectomy. Major hemorrhage from technical failure, although an infrequent occurrence, can cause significant, yet preventable, morbidity or death. Polymer-secured nontransfixion clips are used worldwide for renal pedicle control during laparoscopic nephrectomy, but their use is contraindicated for renal artery ligation during laparoscopic living donor nephrectomy. Laparoscopic staplers are reliable transfixion systems for controlling kidney pedicle. However, stapler malfunction is not negligible, reaching up to 1.7%. A new double shank (DS) titanium-secured nontransfixion clip can dodge legal concerns on polymer-secured clips, while maintaining most of their advantages, without technical failures that may be seen in laparoscopic staplers. New alternatives must be proposed and explored to reach an agreement of the urological community. The new DS-titanium-secured clips could be a step forward toward a safer surgery for kidney donors, at least equivalent to hand ties to occlude the renal artery.

    Background Standard methods for assessment of organ viability during surgery are typically limited to visual cues and tactile feedback in open surgery. However, during laparoscopic surgery, these processes are impaired. This is of particular relevance during laparoscopic renal donation, where the condition of the kidney must be optimized despite considerable manipulation. However, there is no in vivo methodology to monitor renal parenchymal oxygenation during laparoscopic surgery. Methods We have developed a method for the real time, in vivo, whole organ assessment of tissue oxygenation during laparoscopic nephrectomy to convey meaningful biological data to the surgeon during laparoscopic surgery. We apply the 3-CCD (charge coupled device) camera to monitor qualitatively renal parenchymal oxygenation with potential real-time video capability. Results We have validated this methodology in a porcine model across a range of hypoxic conditions, and have then applied the method during clinical laparoscopic donor nephrectomies during clinically relevant pneumoperitoneum. 3-CCD image enhancement produces mean region of interest (ROI) intensity values that can be directly correlated with blood oxygen saturation measurements (R2 > 0.96). The calculated mean ROI intensity values obtained at the beginning of the laparoscopic nephrectomy do not differ significantly from mean ROI intensity values calculated immediately before kidney removal (p > 0.05). Conclusion Here, using the 3-CCD camera, we qualitatively monitor tissue oxygenation. This means of assessing intraoperative tissue oxygenation may be a useful method to avoid unintended ischemic injury during laparoscopic surgery. Preliminary results indicate that no significant changes in renal oxygenation occur as a result of pneumoperitoneum. PMID:18419819

    We report the technique of and initial experience with retroperitoneal laparoscopic live donor right nephrectomy for purposes of renal allotransplantation and autotransplantation. A total of 5 patients underwent retroperitoneoscopic live donor nephrectomy of the right kidney for autotransplantation in 4 and living related renal donation in 1. Indications for autotransplantation included a large proximal ureteral tumor, a long distal ureteral stricture and 2 cases of the loin pain hematuria syndrome. In all cases a 3-port retroperitoneal laparoscopic approach and a pelvic muscle splitting Gibson incision for kidney extraction were used. In patients undergoing autotransplantation the same incision was used for subsequent transplantation. All procedures were successfully accomplished without technical or surgical complications. Total mean operating time was 5.8 hours and average laparoscopic donor nephrectomy time was 3.1 hours. Mean renal warm ischemia time, including endoscopic cross clamping of the renal artery to ex vivo cold perfusion, was 4 minutes. Average blood loss for the entire procedure was 400 cc. Radionuclide scan on postoperative day 1 confirmed good blood flow and function in all transplanted kidneys. Mean analgesic requirement was 58 mg. fentanyl. Mean hospital stay was 4 days (range 2 to 8), and convalescence was completed in 3 to 4 weeks. In the occasional patient requiring renal autotransplantation live donor nephrectomy can be performed laparoscopically with renal extraction and subsequent transplantation through a single standard extraperitoneal Gibson incision, thus, minimizing the overall operative morbidity. Furthermore, these data demonstrate that live donor nephrectomy of the right kidney can be performed safely using a retroperitoneal approach with an adequate length of the right renal vein obtained for allotransplantation or autotransplantation.

    The objective of this study was to evaluate postoperative pain intensity and morphine consumption between living renal donors and patients with renal cell carcinoma undergoing laparoscopic nephrectomy. The clinical trial enrolled 25 living renal donors and 25 patients with renal cell carcinoma undergoing laparoscopic nephrectomy. All underwent similar surgical procedures under general anesthesia. After surgery, morphine patient-controlled analgesia (PCA) was applied to all of them. Data including demographics, surgical details, postoperative morphine consumption, visual analog scale (VAS) scores at rest and during coughing at postoperative 0.5, 2, 4, 8, 12, 24 and 48 hours, side effects, and overall satisfaction degree were compared between the 2 groups. Donors received more intravenous doses of morphine than patients. VAS scores at 2 and 4 hours at rest and during coughing after extubation were significantly higher in donors. The overall satisfaction degree was higher in patients. Living-renal donors suffer more pain and are associated with more morphine consumption than patients with cancer.

    The Australian Safety and Efficacy Register of New Interventional Procedures--Surgical (ASERNIP-S) audit of laparoscopic live-donor nephrectomy commenced in 1999 and concluded in 2003. Six centres in Australia and New Zealand contributed data for 219 donor patients regarding perioperative and postoperative outcome of surgery and short-term follow-up. These data were compared with a recent systematic review of LLDN. The Australasian experience to date compared favourably with worldwide practice, both in terms of efficacy and safety for donors (at least in the short term). The collection of audit data, as this technique was introduced into the Australasian healthcare system, has allowed the local experience with this technique to be pooled and shared, resulting in the development of Australasian practice in line with world's best practice in this area.

    Despite increases in the performance of pure laparoscopic living donor hepatectomy, variations in the bile duct or portal vein have been regarded as relative contraindications to this technique [1-3]. This report describes a donor with separate right posterior and right anterior hepatic ducts and portal veins who underwent pure laparoscopic living donor right hemihepatectomy, integrated with 3D laparoscopy and indocyanine green (ICG) near-infrared fluorescence cholangiography [1, 4, 5]. A 50-year-old man offered to donate part of his liver to his older brother, who required a transplant for hepatitis B-associated liver cirrhosis and hepatocellular carcinoma. Donor height was 178.0 cm, body weight was 82.7 kg, and body mass index was 26.1 kg/m(2). Preoperative computed tomography and magnetic resonance cholangiopancreatography showed that the donor had separate right posterior and right anterior hepatic ducts and portal veins. The entire procedure was performed under 3D laparoscopic view. Following intravenous injections of 0.05 mg/kg ICG, ICG near-infrared fluorescence camera was used to demarcate the exact transection line and determine the optimal bile duct division point. The total operation time was 443 min; the donor required no transfusions and experienced no intraoperative complications. The graft weighed 1146 g with a graft-to-recipient weight ratio of 1.88%. The optimal bile duct division point was identified using ICG fluorescence cholangiography, and the bile duct was divided with good patency without any stricture. The right anterior and posterior portal veins were transected with endostaplers without any torsion. The patient was discharged on postoperative day 8, with no complications. Using a 3D view and ICG fluorescence cholangiography, pure 3D laparoscopic living donor right hemihepatectomy is feasible in a donor with separate right posterior and right anterior hepatic ducts and portal veins.

    Background. A single dose of perioperative dexamethasone (8–10 mg) reportedly decreases postoperative nausea, vomiting, and pain but has not been widely used in laparoscopic donor nephrectomy (LDN). Methods. We performed a retrospective cohort study of living donors who underwent LDN between 2013 and 2015. Donors who received a lower dose (4–6 mg)  (n = 70) or a higher dose (8–14 mg) of dexamethasone (n = 100) were compared with 111 donors who did not receive dexamethasone (control). Outcomes and incidence of postoperative nausea, vomiting, and pain within 24 h after LDN were compared before and after propensity-score matching. Results. The higher dose of dexamethasone reduced postoperative nausea and vomiting incidences by 28% (P = 0.010) compared to control, but the lower dose did not. Total opioid use was 29% lower in donors who received the higher dose than in control (P = 0.004). The higher dose was identified as an independent factor for preventing postoperative nausea and vomiting. Postoperative complication rates and hospital stays did not differ between the groups. After propensity-score matching, the results were the same as for the unmatched analysis. Conclusion. A single perioperative injection of 8–14 mg dexamethasone decreases antiemetic and narcotic requirements in the first 24 h, with no increase in surgical complications. PMID:28210502

    Laparoscopic live donor nephrectomy (DN) has been established as a useful alternative to the traditional open methods of procuring kidneys. To maximize the advantages of the laparoendoscopic single-site (LESS) method, we applied natural orifice specimen extraction to LESS-DN. A 46-year-old woman with no previous abdominal surgery history volunteered to donate her left kidney to her husband and underwent single-port laparoscopic DN with transvaginal extraction. The procedure was completed without intraoperative complications. The kidney functioned well immediately after transplantation, and the donor and recipient were respectively discharged 2 days and 2 weeks postoperatively. Single-port laparoscopic DN and transvaginal graft extraction is feasible and safe. PMID:26878020

    Living donor liver transplantation has failed to become a major means of transplantation in the United States, where <5% of the transplants are performed with living donors. At least 30% to 50% of the complications of donor hepatectomy appear to be related to abdominal wall trauma, including hernia, bowel obstruction, and chronic abdominal discomfort. We analyzed our experience with laparoscopically procured donor hepatectomy. We compared 22 full laparoscopic donor hepatectomies to 20 open/hybrid hepatectomies over an 11-year period. Donor and recipient demographics, complications, and graft and recipient outcomes were analyzed. All 22 laparoscopically procured liver allografts were transplanted successfully. The laparoscopically procured grafts took longer to procure (7 hours 58 minutes versus 6 hours 38 minutes; P < 0.001). The laparoscopically procured cases had lower blood loss (177.3 versus 3753 cc; P < 0.001), a shorter length of stay, and significantly reduced days off work (P = .01). The 1-year graft survival was not different (90% in the laparoscopic group and 85% in the open group; P = 0.70). The 1-year patient survival was not different (95% in the laparoscopic group and 85% in the open group; P = 0.32). There was a trend toward lower wound issues in the laparoscopic group, but this did not reach significance (the hybrid/open group had a 15% hernia rate versus 5% for the laparoscopic group). In experienced living donor centers, laparoscopic liver donation appears to be feasible for all pediatric recipients and some adult recipients. Outcomes for the recipients of laparoscopically procured grafts do not appear significantly different from outcomes with hybrid/open techniques.

    Transplant programs inform potential donors that they should be able to return to normal activities within ~2 weeks and to work by 6 weeks after laparoscopic nephrectomy. We studied actual time. Between 10/2004 and 9/2014, 911 donors having laparoscopic nephrectomy were surveyed 6 months post-donation. Surveys asked questions specific to their recovery experience, including time to return to normal activities and work and a description of their recovery time relative to pre-donation expectations. Of the 911, 646 (71%) responded: mean age at donation was 43.5±10.6 years; 65% were female, 95% were white, 51% were biologically related to their recipient, and 83% reported education beyond high school. Of the 646 respondents, a total of 35% returned to normal activities by 2 weeks post-donation; 79% by 4 weeks post-donation; 94% by 5-6 weeks; however, 6% took >6 weeks. Of the 646, 551 (85%) were working for pay; of these, mean time to return to work was 5.3±2.8 weeks; median, 5 weeks. Of the 551, a total of 14% returned to work in 1-2 weeks, 46% by 3-4 weeks, and 76% by 5-6 weeks. Importantly, 24% required >6 weeks before returning to work with the highest rates for donors in manual labor or a skilled trade. Significantly longer return to work was reported by females (vs males; P=.01), those without (vs those with) post-high school education (P=.010, those with longer hospital stay (P=.01), and those with a postoperative complication (P=.02). Of respondents, 37% described their recovery time as longer than expected. During the donor informed consent process, additional emphasis on realistic expectations around recovery to baseline activities and return to work is warranted.

    We assessed the change in remaining kidney function after laparoscopic donor nephrectomy using serial technetium 99m diethylenetriaminepentaacetic acid (DTPA) scans and investigated the factors affecting the course. Data from 155 donors were obtained from a prospectively maintained database. All donors underwent consecutive DTPA scans preoperatively and 1 month, 6 months and 1 year postoperatively. We investigated the longitudinal change in renal function after surgery and analyzed parameters to influence the perioperative glomerular filtration rate (GFR) change. The changes in GFR according to the DTPA scan presented significant improvement from 1 month up to 2 years after donation (all p < 0.001). The DTPA-GFR of the remaining kidney increased by 14.8% to 58.2 ± 10.6 ml/min/1.73 m(2) (p < 0.001) and by 33.9% to 78.0 ± 14.0 ml/min/1.73 m(2) at 1 month and 1 year after surgery, respectively (p < 0.001). Only 21.9% of donors categorized into chronic kidney disease (CKD) stage 3 or more at 1 year after donation were <60 ml/min/1.73 m(2) according to DTPA-GFR. Multivariate regression analysis revealed that the increase in DTPA-GFR at 1 year was negatively associated with patient age (p = 0.005), BMI (p = 0.04) and preoperative DTPA-GFR of remaining kidney (p = 0.009). The DTPA-GFR of remaining kidney increased steadily for up to 2 years after surgery. Younger donors with lower body mass index and those with lower initial function of the remaining kidney demonstrated a greater increase in DTPA-GFR after nephrectomy. Many of the donors with CKD stage 3 after donation have good renal function according to the results of DTPA-GFR.

    Gastrointestinal (GI) recovery after major abdominal surgery can be delayed from an ongoing need for narcotic analgesia thereby prolonging hospitalization. Enhanced recovery after surgery (ERAS) is a multimodal perioperative care pathway designed to facilitate early recovery after major surgery by maintaining preoperative body composition and physiological organ function and modifying the stress response induced by surgical exposure. Enhanced recovery programs (ERPs) in colorectal surgery have decreased the duration of postoperative ileus and the hospital stay while showing equivalent morbidity, mortality, and readmission rates in comparison to the traditional standard of care. This study is a pilot trial to evaluate the benefits of ERAS protocols in living kidney donors undergoing laparoscopic nephrectomy. This is a single-center, non-randomized, retrospective analysis comparing the outcomes of the first 40 live kidney donors subjected to laparoscopic nephrectomy under the ERAS protocol to 40 donors operated prior to ERAS with traditional standard of care. Our ERAS protocol includes reduced duration of fasting with preoperative carbohydrate loading, intraoperative fluid restriction to 3 ml/kg/hr, target urine output of 0.5 ml/kg/hr, use of subfascial Exparel injection (bupivacaine liposome suspension), and postoperative narcotic-free pain regimen with acetaminophen, ketorolac, or tramadol. Short-term patient outcomes were compared using Pearsons's Chi-Squared test for categorical variables and the Kruskal-Wallis test for continuous variables. Additionally, a multivariate analysis was conducted to evaluate factors influencing patient length of stay and likelihood of readmission. ERAS protocol reduced the postoperative median length of stay decreased from 2.0 to 1.0 days (p=0.001). Overall pain scores were significantly lower in the ERAS group (peak pain score 6.0 vs. 8.00, p< 0.001; morning after surgery pain score 3.0 vs. 7.0, p=0.001; lowest pain score 0

    BACKGROUND Implantation of a kidney with a short renal vein is technically more challenging and therefore prone for technique-related complications. It remains unclear whether pre-operative computed tomography angiography (CTA), to assess vascular anatomy of the donor kidney, can be used to predict renal vein length. MATERIAL AND METHODS Right and left renal vein lengths of 100 consecutive kidney donors were measured in an oblique-coronal plane multiplanar reconstruction image of 100 consecutive kidney donors in whom ex vivo vein length was measured after recovery. In a second retrospective cohort of 100 consecutive kidney donors donating a right kidney, preoperative CTA vein length measurements were correlated to anastomosis time and early graft outcome. RESULTS Left and right renal vein lengths, measured on CTA, were 43.2 mm and 30.0 mm, respectively. No correlation was found between CTA and ex vivo measurements for the left renal vein (p=.610), whereas a significant correlation was found for the right renal vein (p=.021). In the retrospective cohort, right renal vein length was significantly correlated with the anastomosis time but not with early graft outcome. CONCLUSIONS The length of the right, but not the left, renal vein can be predicted by preoperative CTA, but this does not hold true for the left renal vein.

    The aim of this study was to provide a systematic review and meta-analysis of reports comparing laparoendoscopic single-site (LESS) living-donor nephrectomy (LDN) vs standard laparoscopic LDN (LLDN). A systematic review of the literature was performed in September 2013 using PubMed, Scopus, Ovid and The Cochrane library databases. Article selection proceeded according to the search strategy based on Preferred Reporting Items for Systematic Reviews and Meta-analyses criteria. Weighted mean differences (WMDs) were used to measure continuous variables and odds ratios (ORs) to measure categorical ones. Nine publications meeting eligibility criteria were identified, including 461 LESS LDN and 1006 LLDN cases. There were more left-side cases in the LESS LDN group (96.5% vs 88.6%, P < 0.001). Meta-analysis of extractable data showed that LLDN had a shorter operative time (WMD 15.06 min, 95% confidence interval [CI] 4.9-25.1; P = 0.003), without a significant difference in warm ischaemia time (WMD 0.41 min, 95% CI -0.02 to 0.84; P = 0.06). Estimated blood loss was lower for LESS LDN (WMD -22.09 mL, 95% CI -29.5 to -14.6; P < 0.001); however, this difference was not clinically significant. There was a greater likelihood of conversion for LESS LDN (OR 13.21, 95% CI 4.65-37.53; P < 0.001). Hospital stay was similar (WMD -0.11 days, 95% CI -0.33 to 0.12; P = 0.35), as well as the visual analogue pain score at discharge (WMD -0.31, 95% CI -0.96 to 0.35; P = 0.36), but the analgesic requirement was lower for LESS LDN (WMD -2.58 mg, 95% CI -5.01 to -0.15; P = 0.04). Moreover, there was no difference in the postoperative complication rate (OR 1.00, 95% CI 0.65-1.54; P = 0.99). Renal function of the recipient, as based on creatinine levels at 1 month, showed similar outcomes between groups (WMD 0.10 mg/dL, -0.09 to 0.29; P = 0.29). In conclusion, LESS LDN represents an emerging option for living kidney donation. This procedure offers comparable surgical and early

    Although various hand assist devices have been commercialized for people with paralysis, they are somewhat limited in terms of tool fixation and device attachment method. Hand exoskeleton robots allow users to grasp a wider range of tools but are heavy, complicated, and bulky owing to the presence of numerous actuators and controllers. The GRIPIT hand assist device overcomes the limitations of both conventional devices and exoskeleton robots by providing improved tool fixation and device attachment in a lightweight and compact device. GRIPIT has been designed to assist tripod grasp for people with spinal cord injury because this grasp posture is frequently used in school and offices for such activities as writing and grasping small objects. The main development objective of GRIPIT is to assist users to grasp tools with their own hand using a lightweight, compact assistive device that is manually operated via a single wire. GRIPIT consists of only a glove, a wire, and a small structure that maintains tendon tension to permit a stable grasp. The tendon routing points are designed to apply force to the thumb, index finger, and middle finger to form a tripod grasp. A tension-maintenance structure sustains the grasp posture with appropriate tension. Following device development, four people with spinal cord injury were recruited to verify the writing performance of GRIPIT compared to the performance of a conventional penholder and handwriting. Writing was chosen as the assessment task because it requires a tripod grasp, which is one of the main performance objectives of GRIPIT. New assessment, which includes six different writing tasks, was devised to measure writing ability from various viewpoints including both qualitative and quantitative methods, while most conventional assessments include only qualitative methods or simple time measuring assessments. Appearance, portability, difficulty of wearing, difficulty of grasping the subject, writing sensation, fatigability

    A wandering spleen is a rare condition with an unknown incidence. The lack of short gastric vessels and suspensory ligaments is thought to result from a fusion anomaly of the dorsal mesogastrium of the spleen. The major risk in performing a splenectomy for patients with a wandering spleen is overwhelming postsplenectomy infection (OPSI). The incidence of OPSI is 0.13% to 8.1%, with a mortality rate of 30% to 60%. Laparoscopic splenopexy provides the benefits of minimally invasive surgery while avoiding the complications of splenectomy. The reported case presents a patient with a wandering spleen. The patient, an 18-year-old woman, experienced a malarial infection at the age of 5 years and had a computed tomography (CT) scan documenting her spleen in the normal anatomic position. When she was 18 years old, a CT scan showed her spleen located in the right lower quadrant (RLQ). At laparoscopy, the presence of the spleen in the RLQ was confirmed. The spleen could not be easily manipulated with laparoscopic instruments, so a hand port was used to mobilize the spleen to the left upper quadrant (LUQ). No evidence of attenuated suspensory ligaments was seen. The spleen was secured in the left subdiaphragmatic location by the use of a Vicryl mesh bag. An omental sling was used to support the spleen further. A 1-year follow up CT confirmed that the spleen still was located in the correct anatomic position. This is a unique case in that the patient was known to have a normally located spleen at a young age and then found to have a wandering spleen later in life. This could have resulted from a congenital fusion anomaly or attenuation of the patient's suspensory ligaments caused by her previous malarial infection and splenomegaly.

    As the beginning of living-donor kidney transplantation, physicians have expressed concern about the possibility that unilateral nephrectomy can be harmful to a healthy individual. To investigate whether the elevated intra-abdominal pressure (IAP) during laparoscopic donor nephrectomy causes early damage to the remaining kidney, we evaluated urine biomarkers after laparoscopic donor nephrectomy. We measured albumin and alpha-1-microglobulin (α-1-MGB) in urine samples collected during and after open and laparoscopic donor nephrectomy and laparoscopic cholecystectomy and colectomy. Additionally, kidney injury molecule 1 (KIM-1) and neutrophil gelatinase-associated lipocalin (NGAL) were measured in urine samples collected during and after laparoscopic donor nephrectomy and colectomy. The same biomarkers were studied in patients randomly assigned to standard or low IAP during laparoscopic donor nephrectomy. We observed a peak in urinary albumin excretion during all procedures. Urine α-1-MGB rose in the postoperative period with a peak on the third postoperative day after donor nephrectomy. Urine α-1-MGB did not increase after laparoscopic cholecystectomy and colectomy. After laparoscopic nephrectomy, we observed slight increases in urine KIM-1 during surgery and in urine NGAL at day 2-3 after the procedure. After laparoscopic colectomy, both KIM-1 and NGAL were increased in the postoperative period. There were no differences between the high- and low-pressure procedure. Elevated urinary α-1-MGB suggests kidney damage after donor nephrectomy, occurring irrespective of IAP during the laparoscopic procedure.

    Indocyanine green (ICG) near-infrared (NIR) fluorescence cholangiography (FC) has shown its usefulness to visualize the biliary ducts in open living donor hepatectomy (LDH) to check the intraoperative biliary anatomy. The fully laparoscopic LDH approach has been recently described. However, this procedure is very demanding for a possible misperception of right parenchymal transection line and the cut point of the lobar biliary ducts (BD). To explore the potential of ICG-NIR-FC method we report our experience in 11 fully laparoscopic left LDH using 5 different protocols. Protocol-A, consisted on intravenous (i.v.) ICG injection of 2.5 mg with immediate cut of the BD; -B, same dose and late cut; -C, 1 mg i.v. and late cut; -D, intra-cystic duct injection of 2.5 mg and immediate cut; -E, intra-cystic injection of 5 mg and immediate cut. Protocol-A showed fast fluorescence in the lobar artery and portal vein followed by the BD sheet ; -B showed intraductal excretion with a high parenchymal signal; -C showed a very week signal; -D failed to visualize the ducts; -E showed a good signal without parenchymal fluorescence. ICG-NIR-FC is an additional method to visualize the lobar ducts in fully laparoscopy LDH, but still insufficient for the segmental ducts.

    The goal of this study is to compare surgical and oncological outcomes of laparoscopic nephroureterectomy and the open surgery using the concept of systemic inflammatory response syndrome (SIRS) in addition to common variables. Thirty-six and 23 patients having upper urinary tract urothelial cancer who were operated on with retroperitoneoscopic hand-assisted nephroureterectomy (RHANU) or standard open nephroureterectomy (ONU) retrospectively, were analyzed. Median operation time was 140 (range 70-200) and 60 (range 45-85) minutes, respectively in the RHANU group and the ONU group. The median days to ambulation and hospital stay of the RHANU group were significantly shorter than those of the ONU group. There was no significant difference in the incidence of SIRS and other surgical results between the two groups. In oncological outcome, no significant difference was found in the bladder recurrence rate (RHANU vs. ONU; 52% vs. 45%), local recurrence (0% vs. 0%), distant metastasis (11% vs. 13%) or survival rate (94% vs. 91%) between the RHANU group and the ONU group at 2-year follow-up. There was no port site recurrence in the RHANU group. Although the RHANU may have an advantage in terms of earlier recovery, there were no significant differences in the incidence of SIRS and oncological outcomes between the RHANU group and the ONU group.

    The present study assessed preoperative splenic artery embolization using spherical embolic material, super absorbent polymer microspheres (SAP-MS), before laparoscopic or laparoscopically assisted splenectomy. Distal splenic artery embolization using 250 to 400 microm SAP-MS was performed in nine cases with ITP and in seven cases with the other diseases with splenomegaly. Laparoscopic or laparoscopically assisted splenectomies, including a hand-assisted procedure and the procedure involving left upper minilaparotomy, were done 2 to 4 hours after embolization. Conversion to traditional laparotomy was not required in any of the 16 cases, while conversion to 12-cm laparotomy was required in one case with massive splenomegaly. Mean operating time was 161 minutes, and mean intraoperative blood loss was 290 mL. No major postoperative complications were identified, and only one patient reported postembolic pain before surgery. Preoperative splenic artery embolization using painless embolic material, SAP-MS, would be effective for easy and safe laparoscopic or laparoscopically assisted splenectomy.

Similarly, new hemostatic devices such as the ultrasonic scalpel and the electrothermal bipolar vessel sealer may be particularly helpful for extensive colonic mobilizations, in which several vascular pedicles must be taken. The precise role of these hemostatic technologies has yet to be established, particularly in comparison with stapling devices and significantly cheaper laparoscopic clips. Finally, recent advances in camera systems are promising to improve the ease with which difficult colonic dissections can be performed.

    Surgical site infection (SSI) and incisional hernia (IH) are among the most common complications after colorectal surgery. While many risk factors for these complications are unavoidable, evidence suggests that use of Pfannenstiel incisions for specimen extraction during laparoscopic procedures may reduce their incidence. The objectives of this study were to identify risk factors for extraction site SSI (primary objective) and IH (secondary objective) in patients undergoing laparoscopic colorectal surgery. Patients who underwent laparoscopic colorectal resections at The Ohio State University Wexner Medical Center between January 2006 and October 2012 were included. In addition to reviewing medical records, data were gathered from patient questionnaires with a focus on two end points: extraction site SSI and IH. Univariate logistic regression analysis was performed to identify significant associations between the two end points and the following variables: age, gender, ASA (American Society of Anesthesiologists) score, cancer, inflammatory bowel disease (IBD), body mass index (BMI), diabetes, chronic obstructive pulmonary disease, use of immunosuppressant medications, chemotherapy, radiation therapy, smoking, surgical history, surgery duration, duration of follow-up, use of hand-assistance, and utilization of Pfannenstiel incisions for specimen extraction. Multivariate analysis was performed for significant variables. A total of 419 patients met the inclusion criteria. The incidence of SSI was 10.3%. Higher BMI, presence of IBD, younger age, and hand-assisted procedures were associated with a significantly higher risk of SSI. Use of Pfannenstiel extraction sites was associated with lower infection rates; however, this association was not statistically significant. IBD, BMI, and hand-assistance were statistically significant on multivariate analysis. Odds ratios for SSI with IBD, hand-assistance and BMI (per unit increase) were 3.3, 2.2, and 1.06, respectively

    Adrenal pathology requiring surgical intervention is relatively uncommon. Nevertheless, there are a number of conditions that warrant such consideration. Most surgically correctable diseases of the adrenal glands are associated with excess production of adrenal corticosteroids or catecholamines by an adrenal tumor. Classic open approaches toward adrenalectomy in the past have included an anterior, transabdominal, or posterior route. Laparoscopic adrenalectomy offers the advantages of excellent exposure through minimally damaging portals. This results in an expected very benign postoperative course. It has now been almost 4 years since the first reported laparoscopic adrenalectomy. Since then, numerous small series have been reported and experienced laparoscopic surgeons have proven the merits of a laparoscopic approach to adrenalectomy. This reviews the current state of the art and offers descriptions of selected approaches to both the right and left adrenal glands.

    High-quality images can be readily captured during laparoscopic colon surgery, but there are no guidelines for documentation of these video data or how to best measure surgical quality from an operative video. This study evaluates the feasibility and compliance in documenting key steps during laparoscopic right hemicolectomy and sigmoid colectomy. A retrospective review of previously recorded videos of patients undergoing laparoscopic right hemicolectomy or sigmoid colectomy from September to December 2011 in a single institution was performed. Patients' demographics, intraoperative features, postoperative complications, and variables for video recording and editing were collected. Compliance of key surgical steps was assessed using a checklist by two independent surgeons. Sixteen laparoscopic operations (seven right hemicolectomies and nine sigmoid colectomies) were recorded. Twelve (75%) were laparoscopic-assisted, and four (25%) were hand-assisted laparoscopic operations. Compliance with key surgical steps in laparoscopic right hemicolectomy and sigmoid colectomy was demonstrated in the majority of patients, with steps ranging in compliance from 42.9% to 100% and from 77.8% to 100%, respectively. The edited video had a median duration of 3 minutes 47 seconds (range, 1 minute 44 seconds-5 minutes 38 seconds) with a production time of nearly 1 hour and a resolution of 1440 × 1080 pixels. Key surgical steps during laparoscopic right hemicolectomy and sigmoid colectomy can be documented and edited into a short representative video. Standardization of this process should allow video documentation to improve quality in laparoscopic colon surgery.

    The accurate and timely diagnosis of acute appendicitis remains a difficult clinical dilemma. Misdiagnosis rates of up to 40% are not unusual. Laparoscopic appendectomy provides a definitive diagnosis and an excellent method for routine removal of the appendix with very low morbidity and patient discomfort.

    This report describes the case of a young patient who underwent laparoscopic surgery to reduce for a retrograde intussusception of the sigmoid-descending colon caused by adenoma of the sigmoid colon. A 36-year-old woman visited our hospital, complaining primarily of vomiting and abdominal pain. Abdominal CT scan showed the typical finding of intussusception. An emergency colonoscopy revealed that the invaginated colon with a polypoid mass was protruding into the descending colon. A gastrografin enema showed the invaginated bowel segment at the descending colon. We performed endoscopic polypectomy and then hand-assisted laparoscopic reduction. The pathological finding showed tubular adenoma. Laparoscopy is a diagnostic or therapeutic tool for selected cases of adult intussusception. Benign tumor is one of the causes of intussusception in adults and a good indication for laparoscopic surgery. © 2013 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and Wiley Publishing Asia Pty Ltd.

    Hand-Assisted Thoracoscopic Surgery for pulmonary metastasectomy through sternocostal triangle access allows manual palpation of both lungs, thus permitting effective treatment of lung metastases. In our research, 62 patients from November 2001 to January 2012 underwent our Hand-Assisted Thoracoscopic Surgery procedures for pulmonary metastasectomy. Clinical data, including the number of pulmonary metastases determined by Computed Tomography/Positron Emission Tomography-Computed Tomography, surgical findings and survival data of these patients were collected. We found that the median follow-up time was 23.7 months (range 2.4 to 85.6 months). 30 cases of them had post-operative recurrences and the median disease-free survival period was 27.4 months. For Computed Tomography scan, the overall sensitivity for proved metastases was 63% (115/182). 67 non-imaged malignant nodules were palpated and removed in 14 cases. For Positron Emission Tomography-Computed Tomography scan, the overall sensitivity was 66% (79/120). 41 non-imaged malignant nodules were palpated and removed in 12 cases. This study show that the Hand-Assisted Thoracoscopic Surgery provides an easier way for routine bilateral pleural exploration, and thus is critical and effective in detection of non-imaged malignant pulmonary metastases, which might contribute to long-term disease-free survival.

    To assess the value and feasibility of computed tomographic gastrography and multiplanar reformatting in the preoperative evaluation of patients undergoing laparoscopic gastric resection. Fourteen patients with gastric lesions were included in the study. A supine scan was performed after a hypotonic drug, an effervescent agent, and intravenous contrast. This was followed by delayed prone and decubitus scans. We created multiplanar reformats, transparency rendered images, and endoluminal images. The tumours were localized, and distances were measured to the esophagogastric junction and the pylorus. Eleven patients underwent resections. Seven had laparoscopic wedge resections for aberrant pancreas (1 patient), carcinoid (1), Castleman disease (1), and gastrointestinal stromal tumours (GISTs) (4). One patient had an open subtotal gastrectomy for carcinoma due to adhesions. One had a hand-assisted sleeve resection for a gastrointestinal stromal tumour. Two had hand-assisted total gastrectomies for carcinoma and a GIST. For surgical planning, the surgeon rated the imaging extremely useful in 7 and useful in 4. Imaging was extremely useful or useful to localize laparoscopically invisible tumours in 6 patients and to relate tumours to the esophagogastric junction or pylorus and to assess localized vs extensive resection in 8. Correlation was excellent between the preoperative imaging and the intraoperative findings. Computed tomographic gastrography and multiplanar reformatting are useful aids in preoperative planning of laparoscopic gastric resections. Copyright © 2013 Canadian Association of Radiologists.

    After 20 years of experience in laparoscopic liver surgery there is still no clear definition of the best approach (totally laparoscopic [TLS] or hand-assisted [HAS]), the indications for surgery, position, instrumentation, immediate and long-term postoperative results, etc. To report our experience in laparoscopic liver resections (LLRs). Over a period of 10 years we performed 132 LLRs in 129 patients: 112 malignant tumours (90 hepatic metastases; 22 primary malignant tumours) and 20 benign lesions (18 benign tumours; 2 hydatid cysts). Twenty-eight cases received TLS and 104 had HAS. 6 right hepatectomies (2 as the second stage of a two-stage liver resection); 6 left hepatectomies; 9 resections of 3 segments; 42 resections of 2 segments; 64 resections of one segment; and 5 cases of local resections. There was no perioperative mortality, and morbidity was 3%. With TLS the resection was completed in 23/28 cases, whereas with HAS it was completed in all 104 cases. Transfusion: 4,5%; operating time: 150min; and mean length of stay: 3,5 days. The 1-, 3- and 5-year survival rates for the primary malignant tumours were 100, 86 and 62%, and for colorectal metastases 92, 82 and 52%, respectively. LLR via both TLS and HAS in selected cases are similar to the results of open surgery (similar 5-year morbidity, mortality and survival rates) but with the advantages of minimally invasive surgery.

    Instructive laparoscopy videos with appropriate exposition could be ideal for initial training in laparoscopic surgery, but unfortunately there are no guidelines for annotating these videos or agreed methods to measure the educational content and the safety of the procedure presented. Aim of this study is to systematically search the World Wide Web to determine the availability of laparoscopic colorectal surgery videos and to objectively establish their potential training value. A search for laparoscopic right hemicolectomy videos was performed on the three most used English language web search engines Google.com, Bing.com, and Yahoo.com; moreover, a survey among 25 local trainees was performed to identify additional websites for inclusion. All laparoscopic right hemicolectomy videos with an English language title were included. Videos of open surgery, single incision laparoscopic surgery, robotic, and hand-assisted surgery were excluded. The safety of the demonstrated procedure was assessed with a validated competency assessment tool specifically designed for laparoscopic colorectal surgery and data on the educational content of the video were extracted. Thirty-one websites were identified and 182 surgical videos were included. One hundred and seventy-three videos (95%) detailed the year of publication; this demonstrated a significant increase in the number of videos published per year from 2009. Characteristics of the patient were rarely presented, only 10 videos (5.4%) reported operating time and only 6 videos (3.2%) reported 30-day morbidity; 34 videos (18.6%) underwent a peer-review process prior to publication. Formal case presentation, the presence of audio narration, the use of diagrams, and snapshots and a step-by-step approach are all characteristics of peer-reviewed videos but no significant difference was found in the safety of the procedure. Laparoscopic videos can be a useful adjunct to operative training. There is a large and increasing amount of

    2012-01-01

    Background Laparoscopic wedge resection has been widely accepted for small benign gastric tumours. Large gastrointestinal stromal tumours (GISTs), however, can be difficult to manipulate laparoscopically and are at risk for capsule disruption, which can then result in peritoneal seeding. Some authors have suggested that large GISTs (> 8 cm) are best approached using an open technique. However, there has been no consensus as to what the cut-off size should be. We conducted one of the largest Canadian series to date to assess outcomes and follow-up of the laparoscopic management of GISTs. Methods All patients with gastric GISTs presenting to Vancouver General Hospital and University of British Columbia Hospital between 2000 and 2008 were reviewed. Most lesions were resected using a wedge technique with closure of the stomach facilitated by an endoscopic linear stapling device. Results In all, 23 patients presented with GISTs; 19 patients underwent laparoscopic resection and, of these, 15 had a purely laparoscopic operation and 4 had a hand-assisted laparoscopic resection. Mean tumour size was 3.2 cm, with the largest tumour measuring 6.8 cm. There were no episodes of tumour rupture or spillage and no major intraoperative complications. All margins were negative. Mean follow-up was 13.3 (range 1–78) months. There was no evidence of recurrence or metastasis. Conclusion The laparoscopic management of gastric GISTs is safe and effective with short hospital stays and good results over a mean follow-up of 13.3 months. We believe that it should be the preferred technique offered to patients. PMID:22269221

    Summary Laparoscopic donor nephrectomy (LDN) is the gold standard for kidney donation. Recent literature has led to considerable debate regarding the safest route to provide vascular control during this procedure. The most common devices used for vascular control during LDN are staplers and surgical clips. Opinions regarding the safety of these devices vary, as both are prone to dysfunction. Certain clips have already been contraindicated for use on the donor artery owing to reports of catastrophic complications of falling off. Donor safety is paramount to the continued success of renal transplantation in Canada. A review of existing practice at each institution may be called for to ensure the safest standards possible are in place. An appendix to this commentary is available at canjsurg.ca. PMID:28570212

    ABSTRACT Vascular injury in accidental punctures may occur in large abdominal vessels, it is known that 76% of injuries occur during the development of pneumoperitoneum. The aim of this video is to demonstrate two cases of vascular injury occurring during access in laparoscopic urologic surgery. The first case presents a 60-year old female patient with a 3cm tumor in the superior pole of the right kidney who underwent a laparoscopic partial nephrectomy. After the Verres needle insertion, output of blood was verified. During the evaluation of the cavity, a significant hematoma in the inferior vena cava was noticed. After the dissection, a lesion in the inferior vena cava was identified and controlled with a prolene suture, the estimated bloos loss was 300ml. The second case presents a 42-year old female live donor patient who had her right kidney selected to laparoscopic live donor nephrectomy. After the insertion of the first trocar, during the introduction of the 10mm scope, an active bleeding from the mesentery was noticed. The right colon was dissected and an inferior vena cava perforation was identified; a prolene suture was used to control the bleeding, the estimated blood loss was 200mL, in both cases the patients had no previous abdominal surgery. Urologists must be aware of this uncommon, serious, and potentially lethal complication. Once recognized and in the hands of experienced surgeons, some lesions may be repaired laparoscopically. Whenever in doubt, the best alternative is the immediate conversion to open surgery to minimize morbidity and mortality. PMID:28124541

    The aim of the study was the preliminary development of laparoscopic transfer of embryos to the uterus in the pig, which can become the alternative for more invasive surgical methods. We proposed the original method of embryo transfer. Donors (n = 40) and recipients (n = 15) of embryos were sows of age of 6-8 months. The estrus cycle of both recipients and donors was routinely synchronized. The experimental animals were divided into two groups. In the first group (10 donors and 3 recipients) embryos were transplanted according to the method described earlier and in the second group (30 donors and 12 recipients) embryos were transplanted according to our own proposed method. As the control group, we used 16 sows after insemination (AI). In animals from both experimental groups pregnancy was diagnosed between 28-31 day after transplantation and in the control group between 28-31 day after insemination. All animals were observed during pregnancy and weaning period in pig farm. Embryos at the development stage of 2-4 cell were obtained surgically and cultured in vitro for 4 days. Obtained blastocysts were transferred to donors. The original set of catheters for blastocysts transfer to pig uterus was constructed. Three trocars were placed in abdominal cavity for inserting endoscope and 2 grasps for uterus stabilization. After uterus stabilization, the slide was inserted into abdomen which was used for putting the needle to puncture uterus. Through this needle catheter with embryos was inserted into the uterus cavity. Embryos were placed by injection into lumen of the one uterine horn. From 12 recipients pregnancy was diagnosed in 6 recipients. From 6 litters, 57 piglets were born. We weaned 41 piglets (71.9%). In our study we obtained 50% efficacy, with the mean number of 9.5 alive piglets in litter and 6.8 weaned piglets. The efficacy of developed method of laparoscopic transfer of porcine embryos allows it to be used in routine practice.

    Prof Dr Med Erich Mühe of Böblingen, Germany, performed the first laparoscopic cholecystectomy on September 12, 1985. The German Surgical Society rejected Mühe in 1986 after he reported that he had performed the first laparoscopic cholecystectomy, yet in 1992 he received their highest award, the German Surgical Society Anniversary Award. In 1990 in Atlanta, at the Society of American Gastrointestinal Surgeons (SAGES) Convention, Perissat, Berci, Cuschieri, Dubois, and Mouret were recognized by SAGES for performing early laparoscopic cholecystectomies, but Mühe was not. However, in 1999 he was recognized by SAGES for having performed the first laparoscopic cholecystectomy-SAGES invited Mühe to present the Storz Lecture. In Mühe's presentation, titled "The First Laparoscopic Cholecystectomy," which he gave in March 1999 in San Antonio, Texas, he described the first procedure. Finally, Mühe had received the worldwide acclaim that he deserved for his pioneering work. One purpose of this article is to trace the development of the basic instruments used in laparoscopic cholecystectomy. The other purpose is to give Mühe the recognition he deserves for being the developer of the laparoscopic cholecystectomy procedure.

    OBJECTIVE: The authors laparoscopic approach for a Nissen fundoplication is presented. SUMMARY BACKGROUND DATA: The technique has been undertaken in 155 patients over 29 months, with 137 patients having been observed for more than 3 months. METHODS: Three hundred sixty degree fundoplication was undertaken using three or four sutures to secure the wrap. Short gastric vessels were not divided, and the anterior wall of the stomach was used to construct the wrap around the esophagus with a large bougie in position. RESULTS: The operation was not completed laparoscopically in 19 patients because a satisfactory wrap could not be achieved. Ten patients undergoing laparoscopic fundoplication underwent a subsequent operation related to the laparoscopic procedure within 6 months, and there was one postoperative death. Seven other patients were readmitted to the hospital several days subsequent to their discharge, four because of pulmonary emboli. Of 137 patients who have been observed for more than 3 months, 133 patients are well and currently are free from reflux symptoms. CONCLUSIONS: In uncomplicated cases, laparoscopic fundoplication has similar advantages to laparoscopic cholecystectomy. In spite of the fact that it has not yet achieved the overall usefulness of open fundoplication, it seems likely that laparoscopic fundoplication will be used increasingly in the treatment of patients with gastroesophageal reflux disease.

    Abstract Rationale: Laparoscopic total pancreatectomy is a complicated surgical procedure and rarely been reported. This study was conducted to investigate the safety and feasibility of laparoscopic total pancreatectomy. Patients and Methods: Three patients underwent laparoscopic total pancreatectomy between May 2014 and August 2015. We reviewed their general demographic data, perioperative details, and short-term outcomes. General morbidity was assessed using Clavien–Dindo classification and delayed gastric emptying (DGE) was evaluated by International Study Group of Pancreatic Surgery (ISGPS) definition. Diagnosis and Outcomes: The indications for laparoscopic total pancreatectomy were intraductal papillary mucinous neoplasm (IPMN) (n = 2) and pancreatic neuroendocrine tumor (PNET) (n = 1). All patients underwent laparoscopic pylorus and spleen-preserving total pancreatectomy, the mean operative time was 490 minutes (range 450–540 minutes), the mean estimated blood loss was 266 mL (range 100–400 minutes); 2 patients suffered from postoperative complication. All the patients recovered uneventfully with conservative treatment and discharged with a mean hospital stay 18 days (range 8–24 days). The short-term (from 108 to 600 days) follow up demonstrated 3 patients had normal and consistent glycated hemoglobin (HbA1c) level with acceptable quality of life. Lessons: Laparoscopic total pancreatectomy is feasible and safe in selected patients and pylorus and spleen preserving technique should be considered. Further prospective randomized studies are needed to obtain a comprehensive understanding the role of laparoscopic technique in total pancreatectomy. PMID:28099344

    Objective: To describe the clinical characteristics, indications, technical procedures, and outcome of a consecutive series of laparoscopic distal pancreatic resections performed by the same surgical team. Summary Background Data: Laparoscopic distal pancreatic resection has increasingly been described as a feasible and safe procedure, although accompanied by a high rate of conversion and morbidity. Methods: A consecutive series of patients affected by solid and cystic tumors were selected prospectively to undergo laparoscopic distal pancreatectomy performed by the same surgical team. Clinical characteristics as well as diagnostic preoperative assessment and intra- and postoperative data were prospectively recorded. A follow-up of at least 3 months was available for all patients. Results: Fifty-eight patients underwent laparoscopic resection between May 1999 and November 2005. All procedures were successfully performed laparoscopically, and no patient required intraoperative blood transfusion. Splenic vessel preservation was possible in 84.4% of spleen-preserving procedures. There were no mortalities. The overall median hospital stay was 9 days, while it was 10.5 days for patients with postoperative pancreatic fistulae (27.5% of all cases). Follow-up was available for all patients. Conclusions: Our experience in 58 consecutive patients was characterized by the lack of conversions and by acceptable rates of postoperative pancreatic fistulae and morbidity. Laparoscopy proved especially beneficial in patients with postoperative complications as they had a relatively short hospital stay. Solid and cystic tumors of the distal pancreas represent a good indication for laparoscopic resection whenever possible. PMID:17592294

    The main controversy of colon-rectal laparoscopic surgery comes from its use as a cancer treatment. Two points deserve special attention: the incidence of portsite tumor implantation and the possibility of performing radical cancer surgery, such as total mesorectum excision. Once these points are addressed, the laparoscopic approach will be used routinely to treat rectal cancer. To clarify these points, 32 patients with cancer of the lower rectum participated in a special protocol that included preoperative radiotherapy and laparoscopic total mesorectum excision. All data were recorded. At the same time, all data recorded from the experience of a multicenter laparoscopic group (Brazilian Colorectal Laparoscopic Surgeons – 130 patients with tumor of the lower rectum) were analyzed and compared with the data provided by our patients. Analysis of the results suggests that a laparoscopic approach allows the same effective resection as that of conventional surgery and that preoperative irradiation does not influence the incidence of intraoperative complications. The extent of lymph nodal excision is similar to that obtained with open surgery, with an average of 12.3 lymph nodes dissected per specimen. The rate of local recurrence was 3.12%. No port site implantation of tumor was noted in this series of patients with cancer of the lower rectum. PMID:12113422

    Knowing the types and frequency of adrenal vein variants would help surgeons identify and control the adrenal vein during laparoscopic adrenalectomy. To establish the surgical anatomy of the main vein and its variants for laparoscopic adrenalectomy and to analyze the relationship between variant adrenal venous anatomy and tumor size, pathologic diagnosis, and operative outcomes. In a retrospective review of patients at a tertiary referral hospital, 506 patients underwent 546 consecutive laparoscopic adrenalectomies between April 22, 1993, and October 21, 2011. Patients with variant adrenal venous anatomy were compared with patients with normal adrenal venous anatomy regarding preoperative variables (patient and tumor characteristics [size and location] and clinical diagnosis), intraoperative variables (details on the main adrenal venous drainage, any variant venous anatomy, duration of operation, rate of conversion to hand-assisted or open procedure, and estimated blood loss), and postoperative variables (transfusion requirement, reoperation for bleeding, duration of hospital stay, and histologic diagnosis). Laparoscopic adrenalectomy. Prevalence of variant adrenal venous anatomy and its relationship to tumor characteristics, pathologic diagnosis, and operative outcomes. Variant venous anatomy was encountered in 70 of 546 adrenalectomies (13%). Variants included no main adrenal vein identifiable (n = 18), 1 main adrenal vein with additional small veins (n = 11), 2 adrenal veins (n = 20), more than 2 adrenal veins (n = 14), and variants of the adrenal vein drainage to the inferior vena cava and hepatic vein or of the inferior phrenic vein (n = 7). Variants occurred more often on the right side than on the left side (42 of 250 glands [17%] vs. 28 of 296 glands [9%], respectively; P = .02). Patients with variant anatomy compared with those with normal anatomy had larger tumors (mean, 5.1 vs 3.3 cm, respectively; P < .001), more pheochromocytomas (24 of 70 [35%] vs

It confers optimal control of the visual field while operating, ensures stable and smooth displacement of the laparoscope, and allows the operator to work in conditions of restricted surgical assistance, due to either unavailability of staff or economic constraints. It has been tested successfully in pilot studies in laparoscopic gynecologic surgery.

    Abstract The aim of the study was to report surgical outcomes (efficacy and safety) of laparoscopic major hepatectomy for various liver diseases. Although the number of laparoscopic liver resections has increased, expansion of laparoscopic major hepatic resection remains limited, mainly owing to the technical difficulties for the procedure as compared to open surgery. We describe our experiences with laparoscopic major hepatectomy for various liver diseases. We retrospectively reviewed the medical records of 192 patients who underwent laparoscopic major hepatectomy between October 2007 and March 2015 at Asan Medical Center, Korea. The mean age of the patients was 54 ± 11.6 years, and their mean body mass index was 23.5 kg/m2. The most common preoperative diagnosis was hepatocellular carcinoma (n = 82, 42.7%), followed by intrahepatic duct stones (n = 51, 26.6%). We performed 108 left hepatectomies, 55 right hepatectomies, 18 right posterior sectionectomies, 6 right anterior sectionectomies, 2 central bisectionectomies, and 3 donor right hepatectomies. The conversion rate was 1.6% (3 cases) due to bleeding, bile leakage, and uncontrolled hypercapnea during the operation. The mean operation time was 272 ± 80.2 minutes, and the mean estimated blood loss was 300.4 ± 252.2 mL. The mean postoperative hospital stay was 9.8 days. All resection margins were tumor-free in cases of malignant tumors. The morbidity rate was 3.1% (n = 6), including for case of biliary stricture. There were no deaths. Laparoscopic major hepatectomy, including donor hepatectomy, is a safe and feasible option for various liver diseases when careful selection criteria are used by a surgeon experienced with the relevant surgical techniques.

    To establish the safety and feasibility of laparoscopic splenectomy (LS) for littoral cell angioma (LCA). From September 2003 to November 2013, 27 patients were diagnosed with LCA in our institution. These patients were divided into two groups based on operative procedure: LS (13 cases, Group 1) and open splenectomy (14 cases, Group 2). Data were collected retrospectively by chart review. Comparisons were performed between the two groups in terms of demographic characteristics (sex and age); operative outcomes (operative time, estimated blood loss, transfusion, and conversion); postoperative details (length of postoperative stay and complications); and follow-up outcome. LS was successfully carried out in all patients except one in Group 1, who required conversion to hand-assisted LS because of perisplenic adhesions. The average operative time for patients in Group 1 was significantly shorter than that in Group 2 (127 ± 34 min vs 177 ± 25 min, P = 0.001). The average estimated blood loss in Group 1 was significantly lower than in Group 2 (62 ± 48 mL vs 138 ± 64 mL, P < 0.01). No patient in Group 1 required a blood transfusion, whereas one in Group 2 required a transfusion. Two patients in Group 1 and four in Group 2 suffered from postoperative complications. All the complications were cured by conservative therapy. There were no deaths in our series. All patients were followed up and no recurrence or abdominal metastasis were found. LS for patients with LCA is safe and feasible, with preferable operative outcomes and long-term tumor-free survival.

    Current data addressing the role of robotic surgery for the management of colorectal disease are primarily from single-institution and case-matched comparative studies as well as administrative database analyses. The purpose of this study was to compare minimally invasive surgery outcomes using a large regional protocol-driven database devoted to surgical quality, improvement in patient outcomes, and cost-effectiveness. This is a retrospective cohort study from the prospectively collected Michigan Surgical Quality Collaborative registry designed to compare outcomes of patients who underwent elective laparoscopic, hand-assisted laparoscopic, and robotic colon and rectal operations between July 1, 2012 and October 7, 2014. We adjusted for differences in baseline covariates between cases with different surgical approaches using propensity score quintiles modeled on patient demographics, general health factors, diagnosis, and preoperative co-morbidities. The primary outcomes were conversion rates and hospital length of stay. Secondary outcomes included operative time, and postoperative morbidity and mortality. A total of 2735 minimally invasive colorectal operations met inclusion criteria. Conversion rates were lower with robotic as compared to laparoscopic operations, and this was statistically significant for rectal resections (colon 9.0 vs. 16.9%, p < 0.06; rectum 7.8 vs. 21.2%, p < 0.001). The adjusted length of stay for robotic colon operations (4.00 days, 95% CI 3.63-4.40) was significantly shorter compared to laparoscopic (4.41 days, 95% CI 4.17-4.66; p = 0.04) and hand-assisted laparoscopic cases (4.44 days, 95% CI 4.13-4.78; p = 0.008). There were no significant differences in overall postoperative complications among groups. When compared to conventional laparoscopy, the robotic platform is associated with significantly fewer conversions to open for rectal operations, and significantly shorter length of hospital stay for colon operations, without increasing

    Ten years ago the first laparoscopic living donor nephrectomy (LDN) was performed. Today, LDN is a routine operation in many US-American transplantation centers and an increasing number of centers in Europe are practicing LDN. In this article the different aspects of LDN for donor, kidney, recipient and operating surgeon are evaluated. We performed a literature research concerning LDN and the different aspects. Our own experience, as the largest LDN center in Germany, is part of the evaluation. Laparoscopic extraction of a kidney from a living donor is as safe for the donor as the open approach. At the same time, LDN offers multiple advantages like reduced pain and shorter convalescence. For the donated kidney and the recipient no disadvantages occur from the laparoscopic technique, as long as special intra- and perioperative demands are met. For the operating surgeon multiple developments have expanded the technical armentarium. LDN is safe for donor, recipient and kidney. Central issue of an optimal LDN is sufficient experience with laparoscopic urological techniques.

    This study postulates that traditional human error identification techniques fail to consider motion economy principles and, accordingly, their applicability in operating theatres may be limited. This study addresses this gap in the literature with a dual aim. First, it identifies the principles of motion economy that suit the operative environment and second, it develops a new error mode taxonomy for human error identification techniques which recognises motion economy deficiencies affecting the performance of surgeons and predisposing them to errors. A total of 30 principles of motion economy were developed and categorised into five areas. A hierarchical task analysis was used to break down main tasks of a urological laparoscopic surgery (hand-assisted laparoscopic nephrectomy) to their elements and the new taxonomy was used to identify errors and their root causes resulting from violation of motion economy principles. The approach was prospectively tested in 12 observed laparoscopic surgeries performed by 5 experienced surgeons. A total of 86 errors were identified and linked to the motion economy deficiencies. Results indicate the developed methodology is promising. Our methodology allows error prevention in surgery and the developed set of motion economy principles could be useful for training surgeons on motion economy principles.

    BACKGROUND: Performing a surgical procedure in weightlessness has been shown not to be any more difficult than in a 1g environment if the requirements for the restraint of the patient, operator, and surgical hardware are observed. The feasibility of performing a laparoscopic surgical procedure in weightlessness, however, has been questionable. Concerns have included the impaired visualization from the lack of gravitational retraction of the bowel and from floating debris such as blood. METHODS: In this project, laparoscopic surgery was performed on a porcine animal model in the weightlessness of parabolic flight. RESULTS: Visualization was unaffected due to the tethering of the bowel by the elastic mesentery and the strong tendency for debris and blood to adhere to the abdominal wall due to surface tension forces. CONCLUSIONS: There are advantages to performing a laparoscopic instead of an open surgical procedure in a weightless environment. These will become important as the laparoscopic support hardware is miniaturized from its present form, as laparoscopic technology becomes more advanced, and as more surgically capable crew medical officers are present in future long-duration space-exploration missions.

    The success of laparoscopic approach in children has encouraged the application of this technique in young (<2 years) children with non-complicated intussusception. A retrospective analysis of our database provided a total of 4 patients who underwent laparoscopic reduction of intestinal intussusception between 8/2008 and 4/2013. A comprehensive review of each case was done including the video description of the laparoscopic technique of one of them. Four patients (2 boys) were treated by laparoscopy for intestinal intussusception. Mean age was 9 months (5-20 months). Delay time between initial symptoms and diagnosis and between diagnosis and surgery were 3.5 days and 6h respectively. Mean operative time was 35min. There were no conversions. There were no complications. Patients were discharged after 2.5 days (2-4 days). We herein report (video) the laparoscopic approach in a 5 month male child who suffered from a ileocecal intussusception. A 10mm trocar was placed in the left lower quadrant and two 5mm trocars were placed in the upper left quadrant and suprapubic just to the right midline. The cause of the intussusception was identified and the bowel was reduced. A concomitant appendectomy was performed.

    Though initially slow to gain acceptance, the minimally invasive approach to pancreatic resection grew during the last decade and pancreatic operations such as the distal pancreatectomy and pancreatic enucleation are frequently performed laparoscopically. More complex operations such as the pancreaticoduodenectomy may also confer benefits with a minimally invasive approach but are less widely utilized. Though most research to date comparing open and laparoscopic pancreatectomy is retrospective, the current data suggest that compared with open, a laparoscopic procedure may afford postoperative benefits such as less blood loss, shorter hospital stay, and fewer wound complications. Regarding oncologic considerations, despite initial concerns, laparoscopic resection appears to be non-inferior to an open procedure in terms of lymph node retrieval, negative margin rates, and long-term survival. New technologies, such as robotics, are also gaining acceptance. Data show that while the laparoscopic approach incurs higher cost in the operating room, the resulting shorter hospital stay appears to be associated with an equivalent or lower overall cost. The minimally invasive approach to pancreatic resection can be safe and appropriate with significant patient benefits and oncologic non-inferiority based on existing data.

    Laparoscopic repair of inguinal hernia is mini-invasive and has confirmed effects. Femoral hernia could be repaired through the laparoscopic procedures for inguinal hernia. These procedures have clear anatomic view in the operation and preoperatively undiagnosed femoral hernia could be confirmed and treated. Lower recurrence ratio was reported in laparoscopic procedures compared with open procedures for repair of femoral hernia. The technical details of laparoscopic repair of femoral hernia, especially the differences to laparoscopic repair of inguinal hernia are discussed in this article. PMID:27826574

    Laparoscopic adrenalectomy (LA) for phaeochromocytoma is a feasible, safe and effective treatment. The effects of associated catecholamine release render LA more challenging, although with comparable morbidity to LA for other diseases of the adrenal gland. Data from case records of 44 patients who underwent LAs between May 2002 and May 2006 were analysed retrospectively. The patients were divided into a phaeochromocytoma group (Group I) and a non-phaeochromocytoma group (Group II). The aim of this study was to assess the operative course and outcome of LA in the two groups. The mean operating time and blood loss were slightly higher in LA for phaeochromocytomas compared to LA for other pathologies, but these differences were not statistically significant. The mean hospital stay was 3.84 days in both groups. The phaeochromocytoma group had a slightly higher complication rate of 21% compared to 12%. None of the procedures needed open conversion. A terminal hand assist was employed in two patients in Group I and one patient in Group II. Two patients with bilateral phaeochromocytoma had single stage bilateral LA. LA is feasible and effective in phaeochromocytoma. It is associated with a slightly longer operating time, more blood loss and complications when compared with non-phaeochromocytoma masses. LA can be done in a single operation for bilateral masses. Terminal hand assist is a viable and effective option for very large masses.

    Nowadays surgical trainees are faced with a more reduced surgical practice, due to legal limitations and work hourly constraints. Also, currently surgeons are expected to dominate more complex techniques such as laparoscopy. Simulation emerges as a complementary learning tool in laparoscopic surgery, by training in a safe, controlled and standardized environment, without jeopardizing patient' safety. Simulation' objective is that the skills acquired should be transferred to the operating room, allowing reduction of learning curves. The use of simulation has increased worldwide, becoming an important tool in different surgical residency programs and laparoscopic training courses. For several countries, the approval of these training courses are a prerequisite for the acquisition of surgeon title certifications. This article reviews the most important aspects of simulation in laparoscopic surgery, including the most used simulators and training programs, as well as the learning methodologies and the different key ways to assess learning in simulation.

    Laparoscopic fundoplication is widely used today as a surgical standard for gastro-esophageal reflux disease (GERD). However, the procedures are complicated and require advanced laparoscopic skills. In addition, surgical complications correlate with the surgeon's technique and experience. Thus, a training course in laparoscopic fundoplication should be attended before performing surgery. This paper reports on a training course for laparoscopic Nissen fundoplication developed by our group. This course involves practice in suture knotting as part of the laparoscopic operation, practical experience in fundoplication using a porcine organ training model, and observation of a live operation in the operating room. The course improves laparoscopic skills via practical experience and contributes to the learning curve for laparoscopic fundoplication.

    Laparoscopic adenomectomy is a feasible and effective surgical procedure. We have progressively simplified the procedure using barbed sutures and a technique we call "knotless" laparoscopic adenomectomy. We present a prospective, multicenter, descriptive study that reflects the efficacy and safety of this technique in an actual, reproducible clinical practice situation. A total of 26 patients with benign prostatic hyperplasia of considerable size (>80cc) underwent "knotless" laparoscopic adenomectomy. This is an extraperitoneal laparoscopic technique with 4 trocars based on the controlled and hemostatic enucleation of the adenoma using ultrasonic scalpels, precise urethral sectioning under direct vision assisted by a urethral plug, trigonization using barbed suture covering the posterior wall of the fascia, capsulorrhaphy with barbed suture and extraction of the morcellated adenoma through the umbilical incision. The median patient age was 69 (54-83)years, the mean prostate volume was 127 (89-245)cc, the mean operative time was 136 (90-315)min, the mean estimated bleeding volume was 200 (120-500)cc and the hospital stay was 3 (2-6)days. All patients experienced improved function in terms of uroflowmetry and International Prostate Symptom Score and quality of life questionnaires. There were complications in 6 patients, 5 of which were minor. "Knotless" laparoscopic adenomectomy is a procedure with low complexity that combines the advantages of open surgery (lasting functional results and complete extraction of the adenoma) with laparoscopic procedures (reduced bleeding and need for transfusions, shorter hospital stays and reduced morbidity and complications related to the abdominal wall). The use of ultrasonic scalpels and barbed sutures simplifies the procedure and enables a safe and hemostatic technique. Copyright © 2014 AEU. Publicado por Elsevier España, S.L.U.

    OBJECTIVE: The goal of this study was to prospectively define the impact of laparoscopy on the management of patients with a presumed diagnosis of appendicitis. SUMMARY BACKGROUND DATA: While the role of laparoscopy in the management of cholelithiasis is well established, its impact on the management of acute appendicitis needs to be objectively defined and compared to that of conventional management. Several authors have predicted that laparoscopic appendectomy will become the preferred treatment for appendicitis. METHODS: Two groups of consecutive patients with similar clinical characteristics of acute appendicitis were compared. Data on the laparoscopic group were compiled prospectively on standardized forms; data on the conventional group were collected retrospectively. Operative time, hospital stay, analgesia, cost, and return to normal activities were noted. RESULTS: Seventeen consecutive patients who underwent appendectomy were compared to 18 consecutive patients who underwent laparoscopy (16 of these 18 had laparoscopic appendectomy). There was no significant difference between the two groups in terms of clinical characteristics and appendiceal histopathology. The mean operative times were 61 +/- 4.1 minutes and 46 +/- 2.9 minutes for the laparoscopy and conventional groups, respectively (p < 0.01). Hospital stay was significantly shorter in the laparoscopic appendectomy group, with 81% of patients being discharged on their first postoperative day (p < 0.001). The laparoscopic appendectomy patients required significantly less narcotic analgesia (p < 0.02). Return to normal activity was not significantly different between the two groups. The average total cost of laparoscopic appendectomy was 30% greater than that of conventional appendectomy. CONCLUSIONS: Laparoscopy is a useful adjunct to the management of patients with a presumed clinical diagnosis of acute appendicitis. PMID:8239785

    2009-01-01

    Laparoscopic nephroureterectomy (LNU) is becoming an increasingly common alternative treatment for transitional cell carcinoma (TCC) of the renal pelvis and ureter due to decreased perioperative morbidity, shorter hospitalization, and comparable oncologic control with open nephroureterectomy (ONU). Mobilization of the kidney and proximal ureter may be performed through a transperitoneal, retroperitoneal, or hand-assisted approach. Each technique is associated with its own benefits and limitations, and the optimal approach is often dictated by surgeon preference. Our analysis of the literature reflects equivalent cancer control between LPN and OPN at intermediate follow-up with significantly improved perioperative morbidity following LPN. Several methods for bladder cuff excision have been advocated, however, no individual technique for management of the distal ureter proved superior. Overall, complete en-bloc resection with minimal disruption of the urinary tract should be optimized to maintain oncologic outcomes. Longer follow-up and prospective studies are needed to fully evaluate these techniques. PMID:19148293

    Pancreatoduodenectomy is an established procedure for the treatment of benign and malignant diseases located at the pancreatic head and periampullary region. In order to decrease morbidity and mortality, we devised a unique technique using two different jejunal loops to avoid activation of pancreatic juice by biliary secretion and therefore reduce the severity of pancreatic fistula. This technique has been used for open pancreatoduodenectomy worldwide but to date has never been described for laparoscopic pancreatoduodenectomy. This article reports the technique of laparoscopic pylorus-preserving pancreatoduodenectomy with two jejunal loops for reconstruction of the alimentary tract. After pancreatic head resection, retrocolic end-to-side pancreaticojejunostomy with duct-to-mucosa anastomosis is performed. The jejunal loop is divided with a stapler, and side-to-side jejunojejunostomy is performed with the stapler, leaving a 40-cm jejunal loop for retrocolic hepaticojejunostomy. Finally, end-to-side duodenojejunostomy is performed in an antecolic fashion. This technique has been successfully used in 3 consecutive patients with pancreatic head tumors: 2 patients underwent hand-assisted laparoscopic pylorus-preserving pancreatoduodenectomy, and 1 patient underwent totally laparoscopic pylorus-preserving pancreatoduodenectomy. One patient presented a Grade A pancreatic fistula that was managed conservatively. One patient received blood transfusion. Mean operative time was 9 hours. Mean hospital stay was 7 days. No postoperative mortality was observed. Laparoscopic pylorus-preserving pancreatoduodenectomy with double jejunal loop reconstruction is feasible and may be useful to decrease morbidity and mortality after pancreatoduodenectomy. This operation is challenging and may be reserved for highly skilled laparoscopic surgeons.

    Total rectal prolapse is a disorder frequently associated with constipation and anal incontinence. The aim of this study was to evaluate the outcomes of the complications, pain management, hospital stay, constipation, and anal functions of the patients undergoing 2 types of laparoscopic surgical approaches. In this study, 33 patients underwent either laparoscopic rectopexy or hand-assisted laparoscopic resection rectopexy. Preoperative colonic transit time, defecation, postoperative pain scoring, pre-postoperative evaluation of the anal function, and the changes in constipation and relating symptoms were assessed. Postoperative evaluation had been performed at the sixth week and the twelfth month. Median operation time was 137 minutes for rectopexy and 230 minutes for resection rectopexy group. Median postoperative hospital stay was 3 days for patients with rectopexy and 7 days for patients with resection rectopexy. Patients needed painkillers in short postoperative period for pain management in both groups. Continence was improved in 11 of 13 patients (84.6%) in a year after laparoscopic surgery. In 15 patients (45.5%), preoperative constipation either remained in the same or became worse in 7 (21.1%) in a year after surgery. No patient developed recurrence in the median follow-up period, which was about 15 months. Laparoscopic rectopexy and resection rectopexy in the young aged patients working the Army are carried out with less morbidity rate. We eliminated the total prolapse and cure incontinence in almost all patients. In addition to constipation was reduced by laparoscopic surgical approaches in a short time hospitalization with short time painkiller need.

    There are many applications for laparoscopy in small animal surgery. A relatively simple one is abdominal cryptorchid castration. Laparoscopic examination of the peritoneal cavity can both aid in the diagnosis of abdominal cryptorchidism and allow treatment using either a totally laparoscopic or a laparoscopic-assisted technique. Minimally invasive cryptorchid castration obviates the need for "open" celiotomy and may thereby reduce postoperative discomfort and wound-related complications in these patients.

    Objective: To assess the results and contributions of laparoscopy in the management of postoperative bleeding following laparoscopic (LH) or vaginal hysterectomy (VH). Methods: A retrospective study of a 5-year period was carried out on 1167 women who underwent laparoscopic or vaginal hysterectomy. Ten women with postoperative bleeding following laparoscopic or vaginal hysterectomy were identified. Results: The overall incidence of bleeding after laparoscopic or vaginal hysterectomy was 0.85% (10 of 1167). Over the 5-year study period, the incidence fluctuated between 1.1% and 0.4%. Surgical revision was primarily vaginal in 1 woman, followed by laparoscopic control. In 6 patients, laparoscopy was performed immediately. The patients profited from the prompt laparoscopic treatment, because intraabdominal hemorrhage was found and stopped. Of 6 cases of intraperitoneal bleeding, 1 resulted from a blood disorder. The collagen-fibrin agent TachoComb was applied locally, and the patient was postoperatively treated with blood products and coagulation factors. Only bipolar coagulation, TachoComb, and Foley catheter were used to achieve local hemostasis during laparoscopy. The remaining 3 cases where the vaginal cuff was bleeding were managed by vaginal repair and packing without laparoscopy. Conclusion: The laparoscopic approach to postoperative bleeding following laparoscopic or vaginal hysterectomy is an attractive alternative to the abdominal surgical approach. Bleeding following laparoscopic or vaginal hysterectomy can be managed by laparoscopy in the majority of patients. Because the abdominal incision is avoided, the recovery time is reduced.

The overall incidence of bleeding after laparoscopic or vaginal hysterectomy was 0.85% (10 of 1167). Over the 5-year study period, the incidence fluctuated between 1.1% and 0.4%. Surgical revision was primarily vaginal in 1 woman, followed by laparoscopic control. In 6 patients, laparoscopy was performed immediately. The patients profited from the prompt laparoscopic treatment, because intraabdominal hemorrhage was found and stopped. Of 6 cases of intraperitoneal bleeding, 1 resulted from a blood disorder. The collagen-fibrin agent TachoComb was applied locally, and the patient was postoperatively treated with blood products and coagulation factors. Only bipolar coagulation, TachoComb, and Foley catheter were used to achieve local hemostasis during laparoscopy. The remaining 3 cases where the vaginal cuff was bleeding were managed by vaginal repair and packing without laparoscopy. The laparoscopic approach to postoperative bleeding following laparoscopic or vaginal hysterectomy is an attractive alternative to the abdominal surgical approach. Bleeding following laparoscopic or vaginal hysterectomy can be managed by laparoscopy in the majority of patients. Because the abdominal incision is avoided, the recovery time is reduced.

    Anesthesiologists currently view laparoscopic cholecystectomy resemblant to other laparoscopic procedures with respect to the necessity of inducing a pneumoperitoneum via abdominal insufflation of carbon dioxide (CO2). The present case report describes a healthy 63-year-old man who while undergoing elective laparoscopic cholecystectomy under general anesthesia, developed hypoxemia in the course in consequence of pneumothorax. This complication, although rare, can be catastrophic if prompt diagnosis and rapid intervention and management do not come in the nick of time.

    Although the many advantages of laparoscopic surgery have made it an established technique, training in laparoscopic surgery posed problems not encountered in conventional surgical training. Virtual reality simulators open up new perspectives for training in laparoscopic surgery. Under realistic conditions in real time, trainees can tailor their sessions with the VR simulator to suit their needs and goals, and can repeat exercises as often as they wish. VR simulators reduce the number of experimental animals needed for training purposes and are suited to the pursuit of research in laparoscopic surgery.

    Radical cystectomy remains the standard treatment for muscle invasive organ confined bladder carcinoma. Laparoscopic radical cystoprostatectomy (LRC) is an advanced laparoscopic procedure that places significant demands on the patient and the surgeon alike. It is a prolonged procedure which includes several technical steps and requires highly developed laparoscopic skills including intra-corporeal suturing. Here we review the development of the technique, the indications, complications and outcomes. We also examine the potential benefits of robotic-assisted LRC and explore the indications and technique of laparoscopic partial cystectomy. PMID:21206662

    We performed 417 laparoscopic cholecystectomies, including 58 for acute cholecystitis, between September 1991 and April 1995,. All operations were successful, with no mortality or complications. In about 10%, the laparoscopic approach failed and we converted to open cholecystectomy. Average post-operative hospitalization was 24 hours. We also performed primary open cholecystectomies in 55 patients with acute cholecystitis, because of limitations of operating room and staff availability for unscheduled laparoscopic surgery. In these patients, hospital stay was longer and rate of complications higher. In our opinion laparoscopic cholecystectomy is safe and the preferred approach in acute cholecystitis.

    Laparoscopic myomectomy is a minimally invasive surgical option for the treatment of uterine leiomyomas. Single-incision laparoscopy is a relatively new concept that has potential in gynaecological surgery although the technical challenges of single-incision access have limited the widespread use of the technique. The use of intracorporeal suturing is a significant component of the learning curve for laparoscopic myomectomy and presents an even greater challenge with single-incision laparoscopic myomectomy. This article describes a surgeon’s approach to single-incision laparoscopic myomectomy. PMID:21197249

    The standard treatment for patients with early-stage cervical cancer has been radical hysterectomy. However, for women interested in future fertility, radical trachelectomy is now considered a safe and feasible option. The use of minimally invasive surgical techniques to perform this procedure has recently been reported. We report the first case of a laparoscopic radical trachelectomy performed in a developing country. The patient is a nulligravid, 30-y-old female with stage IB1 adenocarcinoma of the cervix who desired future fertility. She underwent a laparoscopic radical trachelectomy and bilateral pelvic lymph node dissection. The operative time was 340 min, and the estimated blood loss was 100mL. There were no intraoperative or postoperative complications. The final pathology showed no evidence of residual disease, and all pelvic lymph nodes were negative. At 20 mo of follow-up, the patient is having regular menses but has not yet attempted to become pregnant. There is no evidence of recurrence. Laparoscopic radical trachelectomy with pelvic lymphadenectomy in a young woman who desires future fertility may also be an alternative technique in the treatment of early cervical cancer in developing countries.

    Volunteer donor apheresis has evolved from early plasmapheresis procedures that collected single components into technically advanced multicomponent procedures that can produce combinations of red blood cells, platelets, and plasma units. Blood collection and utilization is increasing annually in the United States. The number of apheresis procedures is also increasing such that single donor platelet transfusions now exceed platelet concentrates from random donors. Donor qualifications for apheresis vary from those of whole blood. Depending on the procedure, the donor weight, donation interval, and platelet count must be taken into consideration. Adverse effects of apheresis are well known and fortunately occur in only a very small percentage of donors. The recruitment of volunteer donors is one of the most challenging aspects of a successful apheresis program. As multicomponent apheresis becomes more commonplace, it is important for collection centers to analyze the best methods to recruit and collect donors.

    Immunological response to surgical trauma may be protected during laparoscopic surgery. A less surgical trauma, in comparison with conventional surgery, may explained these important advantages. Plasma and macrophages studies have demonstrated that laparoscopic cholecystectomy causes less depression of cell mediated immunity than open cholecystectomy. What will be the impact of this immunological protection in laparoscopic advanced and oncological surgery? Experimental studies have showed that laparoscopic techniques in advanced and oncological surgery may have important advantages concerning the "preservation of the immune status" of the patient. That will imply in the future a lower percentage of infections, local recurrence and even a lower percentage of distant metastases. On the other hand, the appearance of tumor implants in the port sites after laparoscopic resection for cancer is a significant drawback of this procedure. Proper investigations have to be carried out in order to find the cause and the solution of this dilemma.

    Pelvic node dissection has gained widespread acceptance as the final staging procedure in patients with normal acid phospatase and bone scan free of metastatic disease prior to definitive therapy for cure. However, the procedure has had a high morbidity (20-34%) and a major economic impact on the patient due to lengthy hospitalization and recuperative time. The development of laparoscopic biopsy techniques suggests that the need for open surgical lymphadenectomy may be reduced by a laparoscopically performed lymphadenectomy. The goal of this report is to investigate the possibility of laparoscopic pelvic lymphadenectomy in an animal model. Our interest in laparoscopy is based on the ability of this technique to permit tissue removal without the need for major incisions. In laparoscopic cholecystectomy and laparoscopic appendectomy, the surgical procedure is essentially unaltered. The diseased organ is removed and there is no need for a large abdominal incision.

    Introduction. Laparoscopic radical nephroureterectomy (LNU) is being increasingly performed at several centers across the world. We review oncologic outcomes after LNU procedure and the techniques for the management of distal ureter. Materials and Methods. A comprehensive review of the literature was performed on the oncological outcomes and management of distal ureter associated with LNU for upper tract transitional cell carcinoma (TCC). Results and Discussion. LNU for upper tract TCC is performed pure laparoscopically (LNU) or hand-assisted (HALNU). The management of the distal ureter is still debated. LNU appears to have superior perioperative outcomes when compared to open surgery. Intermediate term oncologic outcomes after LNU are comparable to open nephroureterectomy (ONU). Conclusions. Excision of the distal ureter and bladder cuff during nephroureterectomy remains controversial. Intermediate term oncologic outcomes for LNU compare well with ONU. Initial long-term oncologic outcomes are encouraging. Prospective randomized comparison between LNU and open surgery is needed to define the role of these modalities in the current context.

    Purpose. Since laparoscopic hepatectomy (LH) became covered by national health insurance in April 2010 in Japan, the numbers of applied cases and institutions performing it have increased and the indication has expanded. We surveyed the current state and safety of LH in Japan. Methods. A questionnaire survey was performed in 41 institutions related to the Japanese Endoscopic Liver Surgery Study Group and 747 institutions certified by the Japanese Society of Gastroenterological Surgery, and responses concerning all 2962 cases of LH performed by August 2011 were obtained. Results. The surgical procedure employed was hemihepatectomy in 234 (8%), segmentectomy in 88 (3%), left lateral segmentectomy in 434 (15%), segmentectomy in 156 (5%), and partial resection in 1504 (51%) cases. The approach was pure laparoscopy in 1835 (63%), hand-assisted laparoscopic surgery in 201 (7%), and laparoscopy-assisted surgery in 926 (31%). Regarding perioperative complications, surgery was switched to laparotomy in 59 (2.0%), reoperation was performed in 4 (0.1%), and surgery-related death occurred in 2 (0.07%). Intraoperative accidents occurred in 68 (2.3%), and postoperative complications developed in 94 (3.2%). Conclusions. When the selection of cases is appropriate, LH for liver diseases can be safely performed. PMID:28386272

    Vaginal hysterectomy has been shown to have the lowest complication rate, better cosmesis, and decreased cost compared with alternate routes of hysterectomy. However, there are times when a vaginal hysterectomy is not feasible and an open abdominal hysterectomy should be avoided. Minimally invasive surgery has evolved over the last several decades; with the improvement in optics and surgical instruments, laparoscopic hysterectomy is becoming increasingly common. A total laparoscopic hysterectomy is possible with proper training, including sound technique in laparoscopic suturing for closure of the vaginal cuff. Copyright © 2016 Elsevier Inc.

    Background Liver resection is reputed to be one of the most difficult procedures embraced in laparoscopy. This report shows that with adequate training, anatomical liver resection including major hepatectomies can be performed. Methods This is a retrospective study. Results From 1995 to 2004, among 84 laparoscopic liver resections, 46 (54%) anatomical laparoscopic hepatectomies were performed in our institution by laparoscopy. Nine (20%) patients had benign disease while 37 (80%) had malignant lesions. Among those with malignant lesions, 14 patients had hepatocellular carcinoma (HCC), 18 had colorectal metastasis (CRM), while 5 had miscellaneous tumours. For benign disease, minor (two Couinaud's segments or less) and major anatomic hepatectomies were performed in five and four patients, respectively. For malignant lesions, minor and major anatomic hepatectomies were performed in 15 and 22 patients, respectively. Overall, conversion to laparotomy was necessary in 7 (15%) patients. Blood transfusion was required in five (10%) patients. One patient died of cerebral infarction 8 days after a massive peroperative haemorrhage. The overall morbidity rate was 34% whatever the type of resection. Three patients required reoperation, either for haemorrhage (n=1) and/or biliary leak (n=2). For CRM (n=18), overall and disease-free survival at 24 months (mean follow-up of 17 months) were 100% and 56%, respectively. For HCC (n=14), overall and disease-free survival at 36 months (mean follow-up of 29 months) were 91% and 65%, respectively. No port site metastasis occurred in patients with malignancy. Conclusions After a long training with limited liver resection in superficial segments, laparoscopic anatomical minor and major resections are feasible. Short-term carcinological results seem to be similar to those obtained with laparotomy. PMID:18333079

    Nearly 20 years of experience at Severance Hospital has shown that utilizing exchange donors increases the donor pool safely, with outcomes comparable to living related donor grafts. The exchange donor program is invaluable for incompatible donor-recipient pairs to consecutively proceed to transplantation. Recently, newer desensitization protocols have been devised to approach incompatible donor-recipient pairs, but not without risks. These desensitization protocols may be an alternative when confronting the limitations in the exchange program. Therefore, the exchange program and the desensitization protocols should be complementary, not competing strategies and centers should weigh the merits and limitations of each protocol in each incompatible donor-recipient pair to select the optimal method for a safe and successful transplantation.

    Laparoscopic CBD exploration (LCBDE) is a cost effective, efficient and minimally invasive method of treating choledocholithiasis. Laparoscopic Surgery for common bile duct stones (CBDS) was first described in 1991, Petelin (Surg Endosc 17:1705-1715, 2003). The surgical technique has evolved since then and several studies have concluded that Laparoscopic common bile duct exploration(LCBDE) procedures are superior to sequential endolaparoscopic treatment in terms of both clinical and economical outcomes, Cuschieri et al. (Surg Endosc 13:952-957, 1999), Rhodes et al. (Lancet 351:159-161, 1998). We started doing LCBDE in 1998.Our experience with LCBDE from 1998 to 2004 has been published, Gupta and Bhartia (Indian J Surg 67:94-99, 2005). Here we present our series from January 2005 to March 2009. In a retrospective study from January 2005 to March 2009, we performed 3060 laparoscopic cholecystectomies, out of which 342 patients underwent intraoperative cholangiogram and 158 patients eventually had CBD exploration. 6 patients were converted to open due to presence of multiple stones and 2 patients were converted because of difficulty in defining Calots triangle; 42 patients underwent transcystic clearance, 106 patients had choledochotomy, 20 patients had primary closure of CBD whereas in 86 patients CBD was closed over T-tube; 2 patients had incomplete stone clearance and underwent postoperative ERCP. Choledochoduodenosotomy was done in 2 patients. Patients were followed regularly at six monthly intervals with a range of six months to three years of follow-up. There were no major complications like bile leak or pancreatitis. 8 patients had port-site minor infection which settled with conservative treatment. There were no cases of retained stones or intraabdominal infection. The mean length of hospital stay was 3 days (range 2-8 days).

Multiple studies have proved its feasibility, safeness and great advantages. Analyze usefulness and recent advances of endoscopic surgery in the management of gallbladder disease. We did a review of the recent medical literature to determine the actual status of laparoscopic cholecystectomy. Laparoscopic cholecystectomy is the most common surgical procedure performed in the digestive tract. During the year 2001, 1,100,000 cholecystectomies were done in the U.S., 85% were done laparoscopically. In Mexico cholecystectomy in government hospitals is done laparoscopically in 50% of the cases, while in private hospitals it reaches 90%. There are multiple prospective controlled studies showing superiority of laparoscopic cholecystectomy in times of recovery, costs, return to normal activity, pain, morbidity, esthetics among other advantages. Laparoscopic cholecystectomy is the gold standard for the treatment of the great majority of cases of gallbladder disease, nevertheless in developing countries open cholecystectomy is still done frequently.

    Gastric cancer is a leading cause of cancer-related mortality worldwide. We have invented a novel hand-assist device that allows the placement of surgical instruments and the maneuvering of the surgeon's hand, and we have established a new hand-assisted laparoscopic technique called Three United Laparoscopic Surgery (TULS) for laparoscopic dissection of advanced gastric cancer. The present study aimed at exploring the usefulness of TULS in the treatment of advanced gastric cardia cancer. A retrospective study on 100 patients with advanced gastric cardia cancer admitted from January 2014 to June 2015 was done. There were 38 cases of TULS, 30 cases of laparotomy, and 32 cases of laparoscopy-assisted surgery. Statistical comparisons between three treatment groups in operative time, incision length, amount of bleeding, number of lymph nodes dissected, time to flatus after surgery, rate of postoperative complications, hospital stay, and expense were done. For lymph node dissection, there were no significant differences between TULS, laparotomy, and laparoscopy-assisted surgery. However, compared with conventional laparotomy, TULS and laparoscopy-assisted surgery were found to be able to minimize incision length, reduce blood loss during surgery, lower postoperative complication rate, and shorten time to flatus and hospital stay. The differences were statistically significant (P < .05). The operative time of TULS was significantly shorter than that of the laparoscopy-assisted surgery (P < .05), and it was comparable to that of laparotomy. TULS is as efficient as laparotomy in lymph node dissection, and it shows the advantages of minimally invasive surgery. It can be considered a novel and promising surgical intervention for treatment of advanced gastric cancer.

    2012-01-01

    Due to the concern of risk of intra- and postoperative complications and associated morbidity, cirrhosis of the liver is often considered a contraindication for laparoscopic cholecystectomy (LC). This article intends to review the literature and underline the various approaches to dealing with this technically challenging procedure. A Medline search of major articles in the English literature on LC in cirrhotic patients over a 16-y period from 1994 to 2011 was reviewed and the findings analyzed. A total of 1310 cases were identified. Most the patients who underwent LC were in Child-Pugh class A, followed by Child-Pugh classes B and C, respectively. The overall conversion rate was 4.58%, and morbidity was 17% and mortality 0.45%. Among the patients who died, most were in Child-Pugh class C, with a small number in classes B and A. The cause of death included, postoperative bleeding, liver failure, sepsis, duodenal perforation, and myocardial infarction. A meta-analysis of 400 patients in the literature, comparing outcomes of patients undergoing LC with and without cirrhosis, revealed higher conversion rate, longer operative time, higher bleeding complications, and overall increased morbidity in patients with cirrhosis. Safe LC was facilitated by measures that included the use of ultrasonic shears and other hemostatic measures and using subtotal cholecystectomy in patients with difficult hilum and gallbladder bed. Laparoscopic cholecystectomy can be safely performed in cirrhotic patients, within Child-Pugh classes A and B, with acceptable morbidity and conversion rate.

    On the basis of literature and of 475 laparoscopic cholecystectomies of the authors, some pitfalls are reviewed. The circumstances, the mechanism and the prevention of injuries were detailed together with the connected problem of postoperative bile leakage. Among the cholangiographic pitfalls the importance of detection of congenital and acquired anomalies of the biliary tree by means of preoperative ERCP or intraoperative trans-cystic cholangiograms was emphasized. A particular study was made of 3 pictures: Mirizzi syndrome; stone impaction in Vater's papilla; no retrograde flow of the common hepatic duct on intraoperative cholangiograms. Biliodigestive fistulas were briefly commented. The problems with cystic duct stones, particularly the treatment of stones in a long, low inserted cystic duct with retroduodenal course and the closing of thick-walled or wide cystic stumps, were explained. In patients with intraoperative residual common bile duct stones and with failed preoperative catheterization of the papilla, the authors advocate their double approach technique. This combined intraoperative laparoscopic and postoperative endoscopic procedure is carried out via the same transcystic polythene catheters as used for cholangiography and external biliary drainage of the common bile duct.

    1993-10-01

    A technique for laparoscopic Nissen fundoplication is described and a series of 11 cases is presented. The technique secures the patient to the operating table with three safety straps and the patient is then placed in a reverse Trendelenburg position with the hips flexed. The surgeon operates from the patient's right side using two midline trocar sites as the main operating ports. Other ports provide retraction and laparoscope access. The liver retractor is held by a mechanical arm. Once the esophageal peritoneum has been opened, the esophagus and diaphragmatic crura are dissected out and elevated by a Penrose drain sling. The short gastrics are divided and the fundus is brought posterior to the esophagus passing from left to right. A large Maloney dilator is placed in the esophagus and the fundal wrap is sutured to the anterior aspect of the stomach by three sutures; the inferior--most of which incorporates the anterior wall of the esophagus. Once the fundoplication is completed, the dilator is replaced by a nasogastric tube. Postoperatively, patients are given clear liquids and when these are tolerated the nasogastric tube is removed. Most patients are discharged on the second or third postoperative day. Operating time averaged 147 min, and all patients returned to unrestricted activity within 2 to 3 weeks. All patients reported complete relief of gastroesophageal reflux. Average follow up was 120 days with a median of 148 days. Long-term follow up is in progress.

    The enhanced dexterity offered by robotic assistance could be excessive for distal pancreatectomy but not enough to improve the outcome of laparoscopic pancreaticoduodenectomy. Total pancreatectomy retains the challenges of uncinate process dissection and digestive reconstruction, but avoids the risk of pancreatic fistula, and could be a suitable operation to highlight the advantages of robotic assistance in pancreatic resections. Eleven laparoscopic robot-assisted total pancreatectomies (LRATP) were compared to 11 case-matched open total pancreatectomies. All operations were performed by one surgeon during the same period of time. Robotic assistance was employed in half of the patients, based on robot availability at the time of surgery. Variables examined included age, sex, American Society of Anesthesiologists score, body mass index, estimated blood loss, need for blood transfusions, operative time, tumor type, tumor size, number of examined lymph nodes, margin status, post-operative complications, 90-day or in-hospital mortality, length of hospital stay, and readmission rate. No LRATP was converted to conventional laparoscopy, hand-assisted laparoscopy or open surgery despite two patients (18.1 %) required vein resection and reconstruction. LRATP was associated with longer mean operative time (600 vs. 469 min; p = 0.014) but decreased mean blood loss (220 vs. 705; p = 0.004) than open surgery. Post-operative complications occurred in similar percentages after LRATP and open surgery. Complications occurring in most patients (5/7) after LRATP were of mild severity (Clavien-Dindo grade I and II). One patient required repeat laparoscopic surgery after LRATP, to drain a fluid collection not amenable to percutaneous catheter drainage. One further patient from the open group required repeat surgery because of bleeding. No patient had margin positive resection, and the mean number of examined lymph nodes was 45 after LRATP and 36 after open surgery. LRATP is feasible

    To review our initial experience with laparoscopic radical cystectomy. Between September 2004 and June 2006 we performed 16 laparoscopic radical cystectomies (14 males and 2 females) with a median age of 63.8 y.o. (51-85). 12 ileal neobladder (with laparoscopic ileal-urethra anastomosis), 3 cutaneous ureteroileostomies and 1 cutaneous ureterostomy were performed as derivation techniques. Median follow up was 12.4 months Mean operation time was 340 minutes. Estimated blood loss was 350 ml. and 3 cases required intra-op blood transfusion. Mean hospitalization discharged was at 7.6 days. Median linph node dissection was 22.9 finding node metastasis in 6 cases. Most frequent complication was ileo in two cases. No local recurrentes in trocar placement was achieved. Laparoscopic Radical cystectomy is a challenged long-lasting procedure but with the advantage of a less transfusion rate and short hospital stay. Oncologycal outcomes are similar as tose from open surgery.

    The use of laparoscopy has been established in improving perioperative and postoperative outcomes for patients with simple appendicitis. Laparoscopic appendectomy is associated with less wound pain, less wound infection, a shorter hospital stay, and faster overall recovery when compared to the open appendectomy for uncomplicated cases. In the past two decades, the use of laparoscopy for the treatment of perforated appendicitis to take the advantages of minimally invasiveness has increased. This article reviewed the prevalence, approaches, safety disclaimers, perioperative and postoperative outcomes of the laparoscopic appendectomy in the treatment of patients with perforated appendicitis. Special issues including the conversion, interval appendectomy, laparoscopic approach for elderly or obese patient are also discussed to define the role of laparoscopic treatment for patients with perforated appendicitis.

    Operative common bile duct exploration, performed in conjunction with cholecystectomy, has been considered the treatment of choice for choledocholithiasis in the presence of an intact gallbladder. With the advent of laparoscopic cholecystectomy, the management of common bile duct stones has been affected. More emphasis is being placed on endoscopic sphincterotomy and options other than operative common duct exploration. Because of this increasing demand, we have developed a new technique for laparoscopic common bile duct exploration performed in the same operative setting as laparoscopic cholecystectomy. A series of five patients who successfully underwent common bile duct exploration, flexible choledochoscopy with stone extraction, and T-tube drainage, all using laparoscopic technique, is reported. Mean postoperative length of hospital stay was 4.6 days. Outpatient T-tube cholangiography was performed in all cases and revealed normal ductal anatomy with no retained stones. Follow-up ranged from 6 weeks to 4 months, and all patients were asymptomatic and had normal liver function tests.

    Due to their numerous advantages, laparoscopic surgical procedures are increasingly becoming common in the operation theatres over the past few decades. Virtual reality training simulators have played a significant role during this transition from traditional to laparoscopic procedures by enhancing surgical skills, such as hand-eye coordination in laparoscopy, and practising surgical scenarios that cannot be easily created using physical models. This paper presents a general framework for such a training simulator while identifying its key components and their specific roles in enhancing various laparoscopic skills. The paper also describes a laparoscopic simulator, developed in our lab, based on the proposed framework. The results are promising and open new doors for research and development.

  2. O-Glycosyl Donors

    López, J. Cristóbal

    O-Glycosyl donors, despite being one of the last successful donors to appear, have developed themselves into a burgeoning class of glycosyl donors. They can be classified in two main types: O-alkyl and O-aryl (or hetaryl) glycosyl donors. They share, however, many characteristics, they can be (1) synthesized from aldoses, either by modified Fisher glycosidation (O-alkyl) or by nucleophilic aromatic substitution (O-aryl or O-hetaryl), (2) stable to diverse chemical manipulations, (3) directly used for saccharide coupling, and (4) chemoselectively activated. Among these, n-pentenyl glycosides stand apart. They were the first O-alkyl glycosyl donors to be described and have paved the way to many conceptual developments in oligosaccharide synthesis. The development of the chemoselectivity-based "armed-disarmed" approach for saccharide coupling, including its stereoelectronic or torsional variants, now extended to other kinds of glycosyl donors, was first recognized in n-pentenyl glycosides. The chemical manipulation of the anomeric substituent in the glycosyl donor to induce reactivity differences between related species (sidetracking) was also introduced in n-pentenyl glycosides. An evolution of this concept, the "latent-active" strategy for glycosyl couplings, first described in thioglycosyl donors (vide infra), has been elegantly applied to O-glycosyl donors. Thus, allyl and vinyl glycosides, 2-(benzyloxycarbonyl)benzyl (BCB) glycosides and 2'-carboxybenzyl (CB) glycosides are useful "latent-active" glycosyl pairs. Finally, unprotected 3-methoxy-2-pyridyl (MOP) glycosides have been used in glycosylation processes with moderate success.

    Twenty domestic pigs with an average weight of 30 kg were subjected to laparoscopic partial splenic resection with the aim of determining the feasibility, reliability, and safety of this procedure. Unlike the human spleen, the pig spleen is perpendicular to the body's long axis, and it is long and slender. The parenchyma was severed through the middle third, where the organ is thickest. An 18-mm trocar with a 60-mm Endopath linear cutter was used for the resection. The tissue was removed with a 33-mm trocar. The operation was successfully concluded in all animals. No capsule tears occurred as a result of applying the stapler. Optimal hemostasis was achieved on the resected edges in all animals. Although these findings cannot be extended to human surgery without reservations, we suggest that diagnostic partial resection and minor cyst resections are ideal initial indications for this minimally invasive approach.

    Guillain-Barre syndrome is an acute neuropathy that rarely compromises bladder function. Conservative management including clean intermittent catheterization and pharmacotherapy is the primary approach for hypocompliant contracted bladder. Surgical treatment may be used in refractory cases to improve bladder compliance and capacity in order to protect the upper urinary tract. We describe a case of pure laparoscopic augmentation ileocystoplasty in a patient affected by Guillain-Barre syndrome. A 15-year-old female, complaining of voiding dysfunction, recurrent urinary tract infection and worsening renal function for three months. A previous history of Guillain-Barre syndrome on childhood was related. A voiding cystourethrography showed a pine-cone bladder with moderate post-void residual urine. The urodynamic demonstrated a hypocompliant bladder and small bladder capacity (190 mL) with high detrusor pressure (54 cmH2O). Nonsurgical treatments were attempted, however unsuccessfully.

    The transperitoneal laparoscopic approach for right adrenalectomy is performed in patients placed in a lateral decubitus position. Four ports are usually needed (2 or 3, 10 mm ports, 1 or 2, 5 mm ports), inserted in the right subcostal area. After liver retraction, the retroperitonéal space is opened close to the liver, exposing the right adrenal gland and the inferior vena cava. The periphrenic fat and the internal side of the gland are dissected close to the right side of the vena cava in order to expose the main adrenal vein. This vein is double clipped. At the inferior pole of the gland, the inferior adrenal artery is ligated with clips. Before removing and extracting the gland, the right side and the upper pole of the gland are dissected last.

    Esophageal cancer invading the muscularis mucosa sometimes involves regional lymph node metastases. However, lymph node metastases are rare in the dorsal area of the thoracic aorta. We describe a patient with an intramucosal esophageal cancer invading the muscularis mucosa, accompanied by lymph node metastases in the dorsal area of the thoracic aorta. These lesions were successfully resected by hand-assisted laparoscopic surgery using a transhiatal approach. A 60-year-old man was diagnosed with superficial esophageal cancer during a routine health examination. Endoscopic examination and ultrasonography revealed a superficial cancer, of diameter 6.0 cm, invading the submucosal layer and intramural metastases caudal to the primary tumor. Enhanced computed tomography and F-deoxyglucose positron emission tomography demonstrated the two metastatic lymph nodes, one in the dorsal area of the thoracic aorta and the other near the left gastric artery. Thoracoscopic radical esophagectomy with three-field lymph node dissection was performed. The metastatic lymph node in the dorsal area of the thoracic aorta was successfully removed by hand-assisted laparoscopic surgery using a transhiatal approach. Histopathological examination showed primary cancer invading the muscularis mucosa and intramural metastases in the lamina propria mucosa and submucosal layer. The pathological diagnosis according to the Japanese classification of esophageal cancer was MtLt, 47 mm, 0-IIa + IIb, pT1a-MM, ie(+), INF-b, ly3, v0, pN4(4a), pIM1, M0, and pstage IVa. The patient underwent two courses of adjuvant chemotherapy, consisting of CDDP and 5-fluorouracil. At present, 1 year and 8 months after surgery, the patient remains alive without tumor recurrence. Although the lymph node in the dorsal area of the thoracic aorta is not recognized as regional nodes of thoracic esophageal cancer, solitary mediastinal metastases from a mucosal cancer may indicate the existence of direct lymphatic flow

    Background and Objectives: We aimed to assess the feasibility and outcomes of complex ureteropelvic junction obstruction cases submitted to robotic-assisted laparoscopic pyeloplasty. Methods: The records of 131 consecutive patients who underwent robotic-assisted laparoscopic pyeloplasty were reviewed. Of this initial population of cases, 17 were considered complex, consisting of either atypical anatomy (horseshoe kidneys in 3 patients) or previous ureteropelvic junction obstruction management (14 patients). The patients were divided into 2 groups: primary pyeloplasty (group 1) and complex cases (group 2). Results: The mean operative time was 117.3 ± 33.5 minutes in group 1 and 153.5 ± 31.1 minutes in group 2 (P = .002). The median hospital stay was 5.19 ± 1.66 days in group 1 and 5.90 ± 2.33 days in group 2 (P = .326). The surgical findings included 53 crossing vessels in group 1 and 5 in group 2. One patient in group 1 required conversion to open surgery because of technical difficulties. One patient in group 2, with a history of hemorrhagic rectocolitis, presented with peritonitis postoperatively due to a small colonic injury. A secondary procedure was performed after the patient had an uneventful recovery. At 3 months, significant improvement (clinical and radiologic) was present in 93% of cases in group 1 and 88.2% in group 2. At 1 year, all patients in group 2 showed satisfactory results. At a late follow-up visit, 1 patient in group 1 presented with a recurrent obstruction. Conclusions: Robotic pyeloplasty appear to be feasible and effective, showing a consistent success rate even in complex situations. Particular care should be observed during the colon dissection in patients with previous colonic pathology. PMID:24680152

    Vascular management of the right renal vein during laparoscopic living donor nephrectomy is still an unsolved problem. This short vessel has limited the use of right kidneys. However, the right kidney should be harvested in some instances. Based on experience in open donor nephrectomy, our unit has used the donor gonadal vein to obtain a longer renal vein in this setting. Four consecutive living related donors with the indication for laparoscopic right nephrectomy underwent this procedure. Three donors were females and the overall average age was 48.5 years. The renal vein was controlled with a 30-mm stapler and we included 5-6 cm of the ipsilateral gonadal vein during the harvest. The donor kidney was perfused and renal vessels prepared under cold conditions. The gonadal vein was opened longitudinally and sutured to the donor right renal vein as a wide tube in 3 cases and as a spiral tube in 1 case with 6-0 monofilament suture. This procedure extended the bench work between 25 to 40 minutes permitting an 2.5- to 3.5-cm extension of the donor vein. The transplantations were performed in the usual mode and the vein enlargement enormously facilitated the implantation surgery. All recipients displayed immediate graft function; no complications were observed with this strategy. Vein extension with the gonadal vein was a simple, safe method to enlarge the renal vein among right living donor kidneys procured using laparoscopy.

    Introduction Traditionally, laparoscopic mesh rectopexy is performed with four ports, in an attempt to improve cosmetic results. Following laparoscopic mesh rectopexy there is a new operative technique called single-port laparoscopic mesh rectopexy. Aim To evaluate the single-port laparoscopic mesh rectopexy technique in control of rectal prolapse and the cosmesis and body image issues of this technique. Material and methods The study was conducted in El Fayoum University Hospital between July 2013 and November 2014 in elective surgery for symptomatic rectal prolapse with single-port laparoscopic mesh rectopexy on 10 patients. Results The study included 10 patients: 3 (30%) males and 7 (70%) females. Their ages ranged between 19 years and 60 years (mean: 40.3 ±6 years), and they all underwent laparoscopic mesh rectopexy. There were no conversions to open technique, nor injuries to the rectum or bowel, and there were no mortalities. Mean operative time was 120 min (range: 90–150 min), and mean hospital stay was 2 days (range: 1–3 days). Preoperatively, incontinence was seen in 5 (50%) patients and constipation in 4 (40%). Postoperatively, improvement in these symptoms was seen in 3 (60%) patients for incontinence and in 3 (75%) for constipation. Follow-up was done for 6 months and no recurrence was found with better cosmetic appearance for all patients. Conclusions Single-port laparoscopic mesh rectopexy is a safe procedure with good results as regards operative time, improvement in bowel function, morbidity, cost, and recurrence, and with better cosmetic appearance.

    Introduction The benefits of antireflux surgery are well established. Laparoscopic techniques have been shown to be generally safe and effective. The aim of this paper was to review the subject of pain following laparoscopic antireflux surgery. Methods A systematic review of the literature was conducted using the PubMed database to identify all studies reporting pain after laparoscopic antireflux surgery. Publications were included for the main analysis if they contained at least 30 patients. Operations in children, Collis gastroplasty procedures, endoluminal fundoplication and surgery for paraoesophageal hernias were excluded. The frequency of postoperative pain was calculated and the causes/management were reviewed. An algorithm for the investigation of patients with pain following laparoscopic fundoplication was constructed. Results A total of 17 studies were included in the main analysis. Abdominal pain and chest pain following laparoscopic fundoplication were reported in 24.0% and 19.5% of patients respectively. Pain was mild or moderate in the majority and severe in 4%. Frequency of pain was not associated with operation type. The authors include their experience in managing patients with persistent, severe epigastric pain following laparoscopic anterior fundoplication. Conclusions Pain following laparoscopic antireflux surgery occurs in over 20% of patients. Some have an obvious complication or a diagnosis made through routine investigation. Most have mild to moderate pain with minimal effect on quality of life. In a smaller proportion of patients, pain is severe, persistent and can be disabling. In this group, diagnosis is more difficult but systematic investigation can be rewarding, and can enable appropriate and successful treatment. PMID:24780664

    Background and Objectives: We present a case of Laparoendoscopic Single Site Surgery (LESS) left adrenalectomy performed with a conventional laparoscope and instruments. Methods: A 45-year-old male was diagnosed with hyperaldosteronism. Computed tomography detected a left adrenal nodule. Bilateral adrenal vein sampling was consistent with a left-sided source for hyperaldosteronism. Results: Total operative time for LESS left adrenalectomy was 120 minutes. The surgery was performed with conventional instruments, a standard 5-mm laparoscope, and a SILS port, with no additional incisions or trocars needed. No complications occurred, and the patient reported an uneventful recovery. Conclusions: LESS adrenalectomy is a feasible procedure. Although articulating instruments and laparoscopes may offer advantages, LESS adrenalectomy can be done without these. PMID:21902983

    Oocyte donation is a complex situation that requires the applicant couple to deal with the presence of the donor in the history of the child conception. Accepting the eggs is not the same thing than accepting the donor. Her place in the child's life depends on how his parents will accept her phantasmal reality beyond her real person. Paying attention to the story told by the donors on their motivations may help parents internalize this conception to three. We show from two clinical observations, that the generosity of donors is connected to personal issues that do not relate to unborn child or its parents. If there are two mothers in oocyte donation, they are not really in competition because there are also two children: the child conceived through donation is that of the project of the couple, the child to which the donor thinks, is and will remain in phantasmal domain, i.e. linked to the personal history of the donor. We also show that the psychological interview fully responds to the donor expectations when it seeks to highlight her motives.

    Iatrogenic complications in laparoscopic surgery, as in any field, stem from human error. In recent years, cognitive psychologists have developed theories for understanding and analyzing human error, and the application of these principles has decreased error rates in the aviation and nuclear power industries. The purpose of this study was to apply error analysis to laparoscopic surgery and evaluate its potential for preventing complications. Our approach is based on James Reason's framework using a classification of errors according to three performance levels: at the skill- based performance level, slips are caused by attention failures, and lapses result form memory failures. Rule-based mistakes constitute the second level. Knowledge-based mistakes occur at the highest performance level and are caused by shortcomings in conscious processing. These errors committed by the performer 'at the sharp end' occur in typical situations which often times are brought about by already built-in latent system failures. We present a series of case studies in laparoscopic surgery in which errors are classified and the influence of intrinsic failures and extrinsic system flaws are evaluated. Most serious technical errors in lap surgery stem from a rule-based or knowledge- based mistake triggered by cognitive underspecification due to incomplete or illusory visual input information. Error analysis in laparoscopic surgery should be able to improve human performance, and it should detect and help eliminate system flaws. Complication rates in laparoscopic surgery due to technical errors can thus be considerably reduced.

    This review focuses on the laparoscopic approach to gastrointestinal emergencies and its more recent indications. Laparoscopic surgery has a specific place in elective procedures, but that does not apply in emergency situations. In specific emergencies, there is a huge range of indications and different techniques to apply, and not all of them are equally settle. We consider that the most controversial points in minimally invasive procedures are indications in emergency situations due to technical difficulties. Some pathologies, such as oesophageal emergencies, obstruction due to colon cancer, abdominal hernias or incarcerated postsurgical hernias, are nearly always resolved by conventional surgery, that is, an open approach due to limited intraabdominal cavity space or due to the vulnerability of the bowel. These technical problems have been solved in many diseases, such as for perforated peptic ulcer or acute appendectomy for which a laparoscopic approach has become a well-known and globally supported procedure. On the other hand, endoscopic procedures have acquired further indications, relegating surgical solutions to a second place; this happens in cholangitis or pancreatic abscess drainage. This endoluminal approach avoids the need for laparoscopic development in these diseases. Nevertheless, new instruments and new technologies could extend the laparoscopic approach to a broader array of potentials procedures. There remains, however, a long way to go. PMID:26973409

    Abstract Backgroud: An important drawback of the traditional technique for harvesting latissimus dorsi (LD) myocutaneous flap is a long, posterior donor-site incision. Current techniques involve endoscopic or robotic harvesting via a combined approach of open and closed surgery, which necessitates an open axillary incision and the use of special retractors. In this paper, we introduce a fully enclosed laparoscopic technique for harvesting LD flap (LDF) using only 3 small trocar ports. This technique eliminates the need for axillary and donor-site incisions and specialized retractors and considerably reduces the incision size. Methods: We performed laparoscopic harvesting of LDF with prosthesis implantation for immediate breast reconstruction (IBR) after nipple-sparing mastectomy in 2 patients with malignant breast neoplasm who wished to avoid a long scar on the back. Results: IBR using this technique was uneventful in both cases, without any donor-site complications or flap failure. Both patients were satisfied with the esthetic results of the procedure, especially the absence of a visible scar on the back. Conclusion: Enclosed laparoscopic harvesting of LDF is simpler and less invasive than the traditional methods. These preliminary results warrant further evaluation in a larger population to validate the benefits of this technique. PMID:27861385

    Exchange-donor programs may prevent the current loss of many suitable living donors. Both incompatible donor-recipient pairs--with ABO incompatibility or positive cross-matches--and compatible pairs who wish to locate more suitable donors should be encouraged to participate in exchange-donor programs. Advantages and limitations of exchange-donor programs must be carefully explained to prevent interfamilial conflict. Exchange-donor programs may relieve shortages of donor organs and offer good posttransplant outcomes. Therefore, this program should be widely implemented.

  3. Transduodenal sphincterotomy in laparoscopic era.

    Indications for transduodenal sphincterotomy have been reduced in recent years, mainly because of the development of endoscopic sphincterotomy and laparoscopic procedures. Endoscopic treatment is effective, but it is necessary to carefully evaluate its indications because the incidence of early and late complications is not negligible. Laparoscopic procedures require advanced and expensive technologies and considerable laparoscopic experience. Transduodenal sphincterotomy is safe and effective, if correctly performed. Some risk factors appear to be related to the incidence of complications that do not significantly differ from those following endoscopic sphincterotomy. Transduodenal sphincterotomy may be still indicated in selected cases, and for this reason it should be considered an essential part of the knowledge of a general surgeon.

    Spilled gallstones have emerged as a new issue in the era of laparoscopic cholecystectomy. We treated a 77-year-old woman who underwent laparoscopic cholecystectomy. Subsequently, a right flank abscess developed. During the cholecystectomy, the gallbladder was perforated and stones were spilled. After a failed attempt to drain the abscess percutaneously, the patient required open drainage, which revealed retained gallstones in the right flank. The abscess resolved, although the patient continued to have intermittent drainage without evidence of sepsis. Review of the literature revealed 127 cases of spilled gallstones, of which 44.1% presented with intraperitoneal abscess, 18.1% with abdominal wall abscess, 11.8% with thoracic abscess, 10.2% with retroperitoneal abscess, and the rest with various clinical pictures. In case of gallstone spillage during laparoscopic cholecystectomy, every effort should be made to locate and retrieve the stones.

    Because of the intricate internal parts of laparoscopic instruments, questions have been raised about the efficacy of cleaning and sterilization techniques. To assess these risks, hamburger meat was inoculated with high concentrations of vegetative pathogens and packed into laparoscopic cannulas. All openings of the cannulas were sealed during steam sterilization cycles ranging from 3 to 10 min in different experiments; cultures were obtained after cooling. Experiments were then performed using heat-resistant spore forms. Our studies showed that both the standard 10-min cycle and the 3-min "flash" were uniformly successful in killing all pathogenic microorganisms. A 7-min steam sterilization was necessary to kill spores within sealed cannulas. We conclude that a standard 10-min cycle within the steam autoclave provides complete sterilization of laparoscopic instruments; the 3-min "flash" sterilization is appropriate and safe for instruments that have been inadvertently contaminated or dropped during a surgical procedure.

    As laparoscopic surgery becomes increasingly accepted as the technique of choice for many procedures, changes in training structure and working practice limit opportunities for trainees to acquire these new skills. A solution to this problem is the development of simulators that help to develop and hone skills before exposure to the operating theater. Several excellent yet costly simulators exist that have been demonstrated to improve laparoscopic skills. Furthermore, several reports in the literature describe the development of "home simulators"; however, each of these has limitations. The development of a home laparoscopic simulator is reported here that is cheap and easy to build and incorporates an extra dimension of practical port insertion as well as a novel design for a mobile light and camera source.

    The purpose of this study was to evaluate the results of a laparoscopic approach to recurrent inguinal hernia repair which dissected the entire inguinal floor and repaired all potential areas of recurrence without producing tension. Both a transabdominal preperitoneal and a totally extraperitoneal laparoscopic approach were utilized. Ninety recurrent hernias were repaired in 81 patients. The patients had 26 indirect, 36 direct, and 26 pantaloon recurrent hernias of which eight had a femoral component. In all but one patient the primary operations were open anterior repairs. The median follow-up was 14 months, ranging from 1 to 28 months. Patients returned to normal activities in an average of 1 week. The only recurrence observed was in the one patient whose primary repair was laparoscopic. When the entire inguinal floor of the recurrent hernia was redissected and buttressed with mesh, early recurrence was eliminated and recovery was shortened.

    Laparoscopic cryptorchidectomy without insufflation was applied in 10 standing bulls aged 3 to 15 months. Nine bulls were preoperatively pointed out intra-abdominal testes by computed tomography. Preoperative fasting for a minimum of 24 hr provided laparoscopic visualization of intra-abdominal area from the kidney to the inguinal region. Surgical procedure was interrupted by intra-abdominal fat and testis size. It took 0.6 to 1.5 hr in 4 animals weighing 98 to 139 kg, 0.8 to 2.8 hr in 4 animals weighing 170 to 187 kg, and 3 and 4 hr in 2 animals weighing 244 and 300 kg to complete the cryptorchidectomy. In conclusion, standing gasless laparoscopic cryptorchidectomy seems to be most suitable for bulls weighing from 100 to 180 kg. PMID:25715955

    Robotic telesurgery is a promising application of robotics to medicine, aiming to enhance the dexterity and sensation of minimally invasive surgery through millimeter-scale manipulators under control of the surgeon. With appropriate communication links, it would also be possible to perform remote surgery for care in rural areas where specialty care is unavailable, or to provide emergency care en route to a hospital. The UC Berkeley/Endorobotics/UCSF Telesurgical Workstation is a master-slave telerobotic system, with two 6 degree of freedom (DOF) robotic manipulators, designed for laparoscopic surgery. The slave robotic has a 2 DOF wrist inside the body to allow high dexterity manipulation in addition to the 4 DOF of motion possible through the entry port, which are actuated by an external gross motion platform. The kinematics and the controller of the system are designed to accommodate the force and movement requirements of complex tasks, including suturing and knot tying. The system has force feedback in 4 axes to improve the sensation of telesurgery. In this paper, the telesurgical system will be introduced with discussion of kinematic and control issues and presentation of in vitro test results.

    Laparoscopic surgery takes place in a closed environment, the peritoneal cavity distended by the pneumoperitoneum whose parameters, such as pressure, composition, humidity and temperature of the gas, may be changed and adapted to influence the intra and postoperative surgical processes. Such changes were impossible in the "open" environment. This review includes recent data on peritoneal physiology, which are relevant for surgeons, and on the effects of the pneumoperitoneum on the peritoneal membrane. The ability to work in a new surgical environment, which may be adapted to each situation, opens a new era in endoscopic surgery. Using nebulizers, the pneumoperitoneum may become a new way to administer intraoperative treatments. Most of the current data on the consequences of the pneumoperitoneum were obtained using poor animal models so that it remains difficult to estimate the progresses, which will be brought to the operative theater by this new concept. However this revolution will likely be used by thoracic or cardiac surgeon who are also working in a serosa. This approach may even appear essential to all the surgeons who are using endoscopy in a retroperitoneal space such as urologists or endocrine surgeons.

    In light of evidence linking radical nephrectomy and consequent suboptimal renal function to adverse cardiovascular events and increased mortality, research into nephron-sparing techniques for renal masses widely expanded in the past two decades. The American Urological Association (AUA) guidelines now explicitly list partial nephrectomy as the standard of care for the management of T1a renal tumors. Because of the increasing utilization of cross-sectional imaging, up to 70% of newly detected renal masses are stage T1a, making them more amenable to minimally invasive nephron-sparing therapies including laparoscopic and robotic partial nephrectomy and ablative therapies. Cryosurgery has emerged as a leading option for renal ablation, and compared with surgical techniques it offers benefits in preserving renal function with fewer complications, shorter hospitalization times, and allows for quicker convalescence. A mature dataset exists at this time, with intermediate and long-term follow-up data available. Cryosurgical recommendations as a first-line therapy are made at this time in limited populations, including elderly patients, patients with multiple comorbidities, and those with a solitary kidney. As more data emerge on oncologic efficacy, and technical experience and the technology continue to improve, the application of this modality will likely be extended in future treatment guidelines.

    Reestablishing continuity after a Hartmann's procedure is considered a major surgical procedure with high morbidity/mortality. The aim of this study was to assess the short-/long-term outcome of laparoscopic restoration of bowel continuity after HP. A prospectively collected database of colorectal laparoscopic procedures (>800) performed between June 2005 and June 2013 was used to identify 20 consecutive patients who had undergone laparoscopic reversal of Hartmann's procedure (LHR). Median age was 65.4. Ten patients (50 %) had undergone surgery for perforated diverticulitis, 3 (15 %) for cancer, and 7 (35 %) for other reasons (volvulus, posttraumatic perforation, and sigmoid perforation from foreign body). Previous HP had been performed laparoscopically in only 3 patients. Median operative time was 162.5 min. All the procedures were completed laparoscopically. Intraoperative complication rate was nil. Post-operative mortality and morbidity were respectively 0 and 10 % (1 pneumonia, 1 bowel obstruction from post-anastomotic stenosis which required resection and redo of the anastomosis). Median time to first flatus was 3 days, to normal diet 5 days. Median hospital stay was 9 days without readmissions. We followed up the patients for a median of 44 months: when asked, all 20 (100 %) said they would undergo the operation (LHR) again; 3 (15 %) had been re-operated of laparoscopic mesh repair for incisional hernia. When performed by experienced surgeons, LHR is a feasible, safe, reproducible operation, which allows early return of bowel function, early discharge and fast return to work for the patient. It has a low morbidity rate.

    With advancements in minimal access surgery, combined laparoscopic procedures are now being performed for treating coexisting abdominal pathologies at the same surgery. In our center, we performed 145 combined surgical procedures from January 1999 to December 2002. Of the 145 procedures, 130 were combined laparoscopic/endoscopic procedures and 15 were open procedures combined with endoscopic procedures. The combination included laparoscopic cholecystectomy, various hernia repairs, and gynecological procedures like hysterectomy, salpingectomy, ovarian cystectomy, tubal ligation, urological procedures, fundoplication, splenectomy, hemicolectomy, and cystogastrostomy. In the same period, 40 patients who had undergone laparoscopic cholecystectomy and 40 patients who had undergone ventral hernia repair were randomly selected for comparison of intraoperative outcomes with a combined procedure group. All the combined surgical procedures were performed successfully. The most common procedure was laparoscopic cholecystectomy with another endoscopic procedure in 129 patients. The mean operative time was 100 minutes (range 30-280 minutes). The longest time was taken for the patient who had undergone laparoscopic splenectomy with renal transplant (280 minutes). The mean hospital stay was 3.2 days (range 1-21 days). The pain experienced in the postoperative period measured on the visual analogue scale ranged from 2 to 5 with a mean of 3.1. Of 145 patients who underwent combined surgical procedures, 5 patients developed fever in the immediate postoperative period, 7 patients had port site hematoma, 5 patients developed wound sepsis, and 10 patients had urinary retention. As long as the basic surgical principles and indications for combined procedures are adhered to, more patients with concomitant pathologies can enjoy the benefit of minimal access surgery. Minimal access surgery is feasible and appears to have several advantages in simultaneous management of two different

    Robotic surgical technology has been adopted by surgeons with and without previous standard laparoscopic experience. The necessity or benefit of prior training and experience in laparoscopic surgery is unknown. We hypothesized that laparoscopic training enhances performance in robotic surgery. Fourteen medical students with no surgical experience were instructed to incise a spiral using the da Vinci(®) surgical robot with time to completion and errors recorded. Each student was then trained for 1 month in standard laparoscopy, but with no further robotic exposure. Training included a validated laparoscopic training program, including timed and scored parameters. After completion of the month-long training, the students repeated the cutting exercise using the da Vinci robot as well as with standard laparoscopic instruments and were scored within the same parameters. The mean time to completely incise the spiral robotically before training was 16.72 min with a mean of 6.21 errors. After 1 month of validated laparoscopic training, the mean robotic time fell to 9:03 min (p=0.0002) with 3.57 errors (p=0.02). Laparoscopic performance after 1 month of validated laparoscopic training was 13.95 min with 6.14 errors, which was no better than pretraining robotic performance (p=0.20) and worse than post-training robotic performance (p=0.01). Formal laparoscopic training improved the performance of a complex robotic task. The initial robotic performance without any robotic or laparoscopic training was equivalent to standard laparoscopic performance after extensive training. Additionally, after laparoscopic training, the robot allowed significantly superior speed and precision of the task. Laparoscopic training may improve the proficiency in operation of the robot. This may explain the perceived ease with which robotics is adopted by laparoscopically trained surgeons and may be important in training future robotic surgeons.

    Electrosurgery is used in virtually every laparoscopic operation. In the early days of laparoscopic surgery, capacitive coupling, associated with hybrid trocars, was thought to be the major cause of laparoscopic electrosurgery injuries. Modern laparoscopy has reduced capacitive coupling, and now insulation failure is thought to be the main cause of electrosurgical complications. The aim of this study was (1) to determine the incidence of insulation failures, (2) to compare the incidence of insulation failure in reusable and disposable instruments, and (3) to determine the location of insulation failures. At four major urban hospitals, reusable laparoscopic instruments were checked for insulation failure using a high-voltage porosity detector. Disposable L-hooks were collected following laparoscopic cholecystectomy and similarly evaluated for insulation failure. Instruments were determined to have insulation failure if 2.5 kV crossed the instrument's insulation to create a closed loop circuit. Statistical analysis was performed using Fisher's exact or chi(2) analysis (*denotes significance set at p < 0.05). Two hundred twenty-six laparoscopic instruments were tested (165 reusable). Insulation failure occurred more often in reusable (19%; 31/165) than in disposable instruments (3%; 2/61; *p < 0.01). When reusable sets were evaluated, 71% (12/17) were found to have at least one instrument with insulation failure. Insulation failure incidence in reusable instruments was similar between hospitals that routinely checked for insulation failure (19%; 25/130) and hospitals that do not routinely check for insulation failures (33%; 7/21; p = 0.16). Insulation failure was most common in the distal third of the instruments (54%; 25/46) compared to the middle or proximal third of the instruments (*p < 0.05). One in five reusable laparoscopic instruments has insulation failure; a finding that is not altered by whether the hospital routinely checks for insulation defects

    Laparoscopic-assisted colectomy is considered to be a less invasive technique, and patients experience less pain and more rapid postoperative recovery. This operation has been indicated for large sessile adenomas or for early invasive carcinomas in Japan. The indications for this procedure in more advanced colorectal carcinomas is controversial. However, based on our experience with 130 cases, laparoscopic-assisted colectomy can be as curative as open colectomy provided that the patients are properly selected. In this review, the technical difficulties of this procedure are also discussed.

    The management of gastrointestinal malignancies continues to evolve with the latest available therapeutic and diagnostic modalities. There are currently two driving forces in the management of these cancers: the benefits of minimally invasive surgery so thoroughly demonstrated by laparoscopic surgery, and the shift toward neoadjuvant chemotherapy for upper gastrointestinal cancers. In order to match the appropriate treatment to the disease, accurate staging is imperative. No technological advances have combined these two needs as much as laparascopic ultrasound to evaluate the liver and peritoneal cavity. We present a concise review of the latest application of laparoscopic ultrasound in management of gastrointestinal malignancy.

    Delayed gastric emptying is a significant postoperative complication of living donor hepatectomy for liver transplantation and may require endoscopic or surgical intervention in severe cases. Although the mechanism of posthepatectomy delayed gastric emptying remains unknown, vagal nerve injury during intraoperative dissection and adhesion formation postoperatively between the stomach and cut liver surface are possible explanations. Here, we present the first reported case of delayed gastric emptying following fully laparoscopic hepatectomy for living donor liver transplantation. Additionally, we also present a case in which symptoms developed after open right hepatectomy, but for which dissection for left hepatectomy was first performed. Through our experience and these two specific cases, we favor a neurovascular etiology for delayed gastric emptying after hepatectomy. PMID:25610698

    Background Inherent to minimally invasive procedures are loss of tactile feedback and loss of three dimensional assessment. Tasks such as vessel identification and dissection are not trivial for the inexperienced laparoscopic surgeon. Advanced surgical imaging, such as 3-CCD (charge-coupled device) image enhancement, can be used to assist with these more challenging tasks and, in addition, offers a method to non-invasively monitor tissue oxygenation during surgery. Study Design In this study, 3-CCD image enhancement is used for the identification of vessels in 25 laparoscopic donor and partial nephrectomy cases. The algorithm is then applied to two laparoscopic nephrectomy cases involving multiple renal arteries. We also utilize the 3-CCD camera to qualitatively monitor renal parenchymal oxygenation during 10 laparoscopic donor nephrectomies (LDNs). Results The mean ROI (region of interest) intensity values obtained for the renal artery and vein (68.40 ± 8.44 and 45.96 ± 8.65, respectively) are used to calculate a threshold intensity value (59.00) that allows for objective vessel differentiation. In addition, we examined the renal parenchyma during LDNs. Mean ROI intensity values were calculated for the renal parenchyma at two distinct time points, prior to vessel stapling (non-ischemic) and just before extraction from the abdomen (ischemic). The non-ischemic mean ROI intensity values are statistically different from the ischemic mean ROI intensity values (p < 0.05), even with short ischemia times. Conclusions We have developed a technique, 3-CCD image enhancement, for the identification of vasculature and for the monitoring of parenchymal oxygenation. This technique requires no additional laparoscopic operating room equipment and has real-time video capability. PMID:18501814

    The Toy-Smoot laparoscopic hernioplasty has been performed on 75 patients with a total of 83 hernioplasties over the past 20 months. Sixty-nine patients were male and six were female. The age range was 20 to 75 years with an average age of 51.5 years. Twelve of the patients had bilateral hernias repaired: 55 direct hernias, 16 indirect hernias, and 5 pantaloon hernias. Eleven of the repairs were for recurrent hernias. The procedure was performed under general anesthesia. The abdomen was insufflated with carbon dioxide, establishing the pneumoperitoneum. Three 11 mm trocars were inserted, the first via the umbilicus, into which the 0 degrees endoscope was inserted. Two additional trocars were inserted at the level of the umbilicus at the anterior axillary lines. The hernia sacs were left in situ. The medial umbilical ligament was dissected medially, so as to identify directly the pubic tubercle and the Cooper's ligament. An expanded PTFE soft tissue patch, 1 mm thick and 7.5 x 10 cm in size, was attached to the Nanticoke Endo-patch spreader and introduced via the contralateral trocar and positioned over the hernia defect. The Endopath EMS stapler was then used to secure the PTFE patch over the hernia defect. This required secure anatomical fixation to the transversalis fascia anteriorly and laterally, the pubic tubercle, and the posterior rectus sheath, medially, Cooper's ligament, posteromedially, and the endoabdominal fascia, posterolaterally. There were a total of seven different complications, one major, which was a bladder injury that required an open repair of the bladder and then an open, conventional hernioplasty.(ABSTRACT TRUNCATED AT 250 WORDS)

  2. Stress response to laparoscopic liver resection

    PubMed Central

    Ueda, Kazuki; Turner, Patricia

    2004-01-01

    Background: The magnitude of the systemic response is proportional to the degree of surgical trauma. Much has been reported in the literature comparing metabolic and immune responses, analgesia use, or length of hospital stay between laparoscopic and open procedures. In particular, metabolic and immune responses are represented by measuring various chemical mediators as stress responses. Laparoscopic procedures are associated with reduced operative trauma compared with open procedures, resulting in lower systemic response. As a result, laparoscopic procedures are now well accepted for both benign and malignant processes. Laparoscopic liver resection, specifically, is employed for symptomatic and some malignant tumors, following improvements in diagnostic accuracy, laparoscopic devices, and techniques. However, laparoscopic liver resection is still controversial in malignant disease because of complex anatomy, the technical difficulty of the procedure, and questionable indications. There are few reports describing the stress responses associated with laparoscopic liver resection, even though many studies reviewing stress responses have been performed recently in both humans and animal models comparing laparoscopic to conventional open surgery. Although this review examines stress response after laparoscopic liver resection in both an animal and human clinical model, further controlled randomized studies with additional investigations of immunologic parameters are needed to demonstrate the consequences of either minimally invasive surgery or open procedures on perioperative or postoperative stress responses for laparoscopic liver resection.

    Backround Laparoscopic adrenalectomy is a promising alternative to open surgery although concerns exist in regard to laparoscopic treatment of pheocromocytoma. This report compares the outcome of laparoscopic and conventional (open) resection for pheocromocytoma particular in regard to intraoperative hemodynamic stability and postoperative patient comfort. Methods Seven patients laparoscopically treated (1997–2000) and nine patients treated by open resection (1990–1996) at the National Hospital (Rikshospitalet), Oslo. Peroperative hemodynamic stability including need of vasoactive drugs was studied. Postoperative analgesic medication, complications and hospital stay were recorded. Results No laparoscopic resections were converted to open procedure. Patients laparoscopically treated had fewer hypertensive episodes (median 1 vs. 2) and less need of vasoactive drugs peroperatively than patients conventionally operated. There was no difference in operative time between the two groups (median 110 min vs. 125 min for adrenal pheochromocytoma and 235 vs. 210 min for paraganglioma). Postoperative need of analgesic medication (1 vs. 9 patients) and hospital stay (median 3 vs. 6 days) were significantly reduced in patients laparoscopically operated compared to patients treated by the open technique. Conclusion Surgery for pheochromocytoma can be performed laparoscopically with a safety comparable to open resection. However, improved hemodynamic stability peroperatively and less need of postoperative analgesics favour the laparoscopic approach. In experienced hands the laparoscopic technique is concluded to be the method of choice also for pheocromocytoma. PMID:11580870

    Laparoscopic hepatectomy continues to be a challenging operation associated with a steep learning curve. This study aimed to evaluate the learning process during 15 years of experience with laparoscopic hepatectomy and to identify approaches to standardization of this procedure. Prospectively collected data of 317 consecutive laparoscopic hepatectomies performed from January 2000 to December 2014 were reviewed retrospectively. The operative procedures were classified into 4 categories (minor hepatectomy, left lateral sectionectomy [LLS], left hepatectomy, and right hepatectomy), and indications were classified into 5 categories (benign-borderline tumor, living donor, metastatic liver tumor, biliary malignancy, and hepatocellular carcinoma). During the first 10 years, the procedures were limited mainly to minor hepatectomy and LLS, and the indications were limited to benign-borderline tumor and living donor. Implementation of major hepatectomy rapidly increased the proportion of malignant tumors, especially hepatocellular carcinoma, starting from 2011. Conversion rates decreased with experience for LLS (13.3% vs 3.4%; p = 0.054) and left hepatectomy (50.0% vs 15.0%; p = 0.012), but not for right hepatectomy (41.4% vs 35.7%; p = 0.661). Our 15-year experience clearly demonstrates the stepwise procedural evolution from LLS through left hepatectomy to right hepatectomy, as well as the trend in indications from benign-borderline tumor/living donor to malignant tumors. In contrast to LLS and left hepatectomy, a learning curve was not observed for right hepatectomy. The ongoing development process can contribute to faster standardization necessary for future advances in laparoscopic hepatectomy. Copyright © 2017 American College of Surgeons.

    Minimally invasive therapy aims to minimize the trauma of any interventional process but still achieve a satisfactory therapeutic result. The development of "critical pathways," rapid mobilization and early feeding have contributed towards the goal of shorter hospital stay. This concept has been extended to include laparoscopic cholecystectomy and hernia repair. Reports have been published confirming the safety of same day discharge for the majority of patients. However, we would caution against overenthusiastic ambulatory laparoscopic cholecystectomy on the rational but unproven assumption that early discharge will lead to occasional delays in diagnosis and management of postoperative complications. Intraoperative complications of laparoscopic surgery are mostly due to traumatic injuries sustained during blind trocar insertion and physiologic changes associated with patient positioning and pneumoperitoneum creation. General anesthesia and controlled ventilation comprise the accepted anesthetic technique to reduce the increase in PaCO2. Investigators have recently documented the cardiorespiratory compromise associated with upper abdominal laparoscopic surgery, and particular emphasis is placed on careful perioperative monitoring of ASA III-IV patients during insufflation. Setting limits on the inflationary pressure is advised in these patients. Anesthesiologists must maintain a high index of suspicion for complications such as gas embolism, extraperitoneal insufflation and surgical emphysema, pneumothorax and pneumomediastinum. Postoperative nausea and vomiting are among the most common and distressing symptoms after laparoscopic surgery. A highly potent and selective 5-HT3 receptor antagonist, ondansetron, has proven to be an effective oral and IV prophylaxis against postoperative emesis in preliminary studies. Opioids remain an important component of the anesthesia technique, although the introduction of newer potent NSAIDs may diminish their use. A preoperative

    Laparoscopic liver resection (LLR) for tumors in the posterosuperior liver [segment (S) 7 and deep S6] is a challenging clinical procedure. This area is located in the bottom of the small subphrenic space (rib cage), with the large and heavy right liver on it when the patient is in the supine position. Thus, LLR of this area is technically demanding because of the handling of the right liver which is necessary to obtain a fine surgical view, secure hemostasis and conduct the resection so as to achieve an appropriate surgical margin in the cage. Handling of the right liver may be performed by the hand-assisted approach, robotic liver resection or by using spacers, such as a sterile glove pouch. In addition, the operative field of posterosuperior resection is in the deep bottom area of the subphrenic cage, with the liver S6 obstructing the laparoscopic caudal view of lesions. The use of intercostal ports facilitates the direct lateral approach into the cage and to the target area, with the combination of mobilization of the liver. Postural changes during the LLR procedure have also been reported to facilitate the LLR for this area, such as left lateral positioning for posterior sectionectomy and semi-prone positioning for tumors in the posterosuperior segments. In our hospital, LLR procedures for posterosuperior tumors are performed via the caudal approach with postural changes. The left lateral position is used for posterior sectionectomy and the semi-prone position is used for S7 segmentectomy and partial resections of S7 and deep S6 without combined intercostal ports insertion. Although the movement of instruments is restricted in the caudal approach, compared to the lateral approach, port placement in the para-vertebra area makes the manipulation feasible and stable, with minimum damage to the environment around the liver.

    Barrett’s esophagus (BE) is a precursor of esophageal adenocarcinoma and is associated with gastroesophageal reflux disease, which is often preceded by a hiatal hernia. We describe a case of esophageal adenocarcinoma arising in long-segment BE (LSBE) associated with a hiatal hernia that was successfully treated with a laparoscopic transhiatal approach (LTHA) without thoracotomy. The patient was a 42-year-old male who had previously undergone laryngectomy and tracheal separation to avoid repeated aspiration pneumonitis. An ulcerative lesion was found in a hiatal hernia by endoscopy and superficial esophageal cancer was also detected in the lower thoracic esophagus. The histopathological diagnosis of biopsy samples from both lesions was adenocarcinoma. There were difficulties with the thoracic approach because the patient had severe kyphosis and muscular contractures from cerebral palsy. Therefore, we performed subtotal esophagectomy by LTHA without thoracotomy. Using hand-assisted laparoscopic surgery, the esophageal hiatus was divided and carbon dioxide was introduced into the mediastinum. A hernial sac was identified on the cranial side of the right crus of the diaphragm and carefully separated from the surrounding tissues. Abruption of the thoracic esophagus was performed up to the level of the arch of the azygos vein via LTHA. A cervical incision was made in the left side of the permanent tracheal stoma, the cervical esophagus was divided, and gastric tube reconstruction was performed via a posterior mediastinal route. The operative time was 175 min, and there was 61 mL of intra-operative bleeding. A histopathological examination revealed superficial adenocarcinoma in LSBE. Our surgical procedure provided a good surgical view and can be safely applied to patients with a hiatal hernia and kyphosis. PMID:26269688

    The development of medical knowledge has resulted in a demand in society for donor organs, but the recruitment of donor organs for transplantation is difficult. This paper aims to provide some general insights into the complex interaction processes involved. A laissez-faire policy, in which market forces are relied on, is not acceptable from an ethical and legal point of view in most western European countries. Especially at the demand side of the exchange of donor organs, commercialism is to be opposed. We judge the use of commercial incentives at the supply side less unacceptable in theory but not feasible in western European countries. Since market forces are deemed unacceptable as instruments for coordinating demand and supply of donor organs, donor procurement has to be considered as a collective good, and therefore governments are faced with the responsibility of making sure that alternative interaction and distribution mechanisms function. The role of organ procurement agencies (OPAs) in societal interaction concerning postmortem organ donation is described using a two-dimensional conceptualisation scheme. Medical aspects of living organ donation are described. An international comparative description of legal systems to regulate living organ donation in western European countries completes this survey.

    PubMed Central

    2016-01-01

    Background The urachus and the urachal remnants represent a failure in the obliteration of the allantois at birth that connects the bladder to the umbilicus. After birth it obliterates and presents as the midline umbilical ligament. Urachal cyst are the most common urachal anomaly in the pediatric population. The traditional surgical approach is a semicircular infraumbilical incision or a lower midline laparotomy. Methods In a 10 years period at Pediatric Surgery Department of Vicenza 16 children were diagnosed with urachal anomalies presenting as abdominal or urinary symptoms. Eight underwent open excision; eight were treated by laparoscopic surgery. The average age was 5.5 years (range, 4 months–13 years) in open group and 10 years (range, 1 month–18 years) in laparoscopic group. Results Mean operative time was 63 minutes (range, 35–105 minutes) in open group, 50 minutes (range, 35–90 minutes) in laparoscopic group. There were no postoperative complications. The patients of laparoscopic group were all discharged after few days (range, 2–4 days). Pathological examination confirmed a benign urachal remnant in all cases. Reporting our experience since comparing the two surgical approaches we want to describe the technique step by step of laparoscopic urachal cyst excision as minimally invasive diagnostic and surgical techniques. Conclusions Laparoscopy represents a useful alternative for the management of persistent or infected urachus, in particular when there’s the suspect despite the lack of radiological evidence. The morbidity associated with this approach is very low as the risk or recurrence. Laparoscopy in the management of urachal cyst is safe effective and ensures good cosmesis with all the advantages of minimally invasive approach. PMID:27867852

    Background. Laparoscopic liver resection (LLR) has emerged as an alternative procedure to open liver resection in selected patients. The purpose of this study was to describe our initial experience of 100 patients undergoing LLR. Methods. We analysed a prospectively maintained hepatobiliary database of 100 patients who underwent LLR between August 2007 and August 2012. Clinicopathological data were reviewed to evaluate surgical outcomes following LLR. Results. The median age was 64 and median BMI 27. Patients had a liver resection for either malignant lesions (n = 74) or benign lesions (n = 26). Commonly performed procedures were segmentectomy/metastectomy (n = 55), left lateral sectionectomy (LLS) (n = 26), or major hepatectomy (n = 19). Complete LLR was performed in 84 patients, 9 were converted to open and 7 hand-assisted. The most common indications were CRLM (n = 62), followed by hepatic adenoma (n = 9) or hepatocellular carcinoma (n = 7). The median operating time was 240 minutes and median blood loss was 250 mL. Major postoperative complications occurred in 9 patients. The median length of stay (LOS) was 5 days. One patient died within 30 days of liver resection. Conclusions. LLR is a safe and oncologically feasible procedure with comparable short-term perioperative outcomes to the open approach. However, further studies are necessary to determine long-term oncological outcomes. PMID:24672143

    2009-12-01

    In response to the increasing interest in minimally invasive surgery by both patients and surgeons, most abdominal surgery today is carried out laparoscopically. Laparoscopic splenectomy has become a gold standard in the treatment of spleen disorders related to hematologic diseases. Increasing laparoscopic surgery experience and improved new vessel sealing equipment have led to a decreasing number of ports in laparoscopic surgery and to operations from 1 incision. We carried out single-incision double-port laparoscopic splenectomy in a patient with immune thrombocytopenic purpura using only 2 trocars with a simple manipulation. Our review of the related literature revealed no earlier description of a single-incision double-port laparoscopic splenectomy. We therefore present herein this earlier unreported technique.

    Background and Objectives: Laparoscopy has acquired an unquestionable position in surgical practice as a diagnostic and operative tool. Recently, the laparoscopic approach has become a valuable option for adrenalectomy. This paper reports, in detail, our experience of laparoscopic adrenalectomy performed for adrenal tumors. Methods: We performed 12 laparoscopic adrenalectomies from October 29, 1997 to October 31, 1998. The technique of laparoscopic adrenalectomy is described thoroughly in all relevant details for either left or right-sided adrenal lesions. Results: The presented technique of laparoscopic adrenalectomy in all 12 cases provided good and relatively simple exposure of the immediate operative area. All relevant vascular elements were safely controlled, adrenal tumors could be successfully removed, and adequate hemostasis was achieved. No intraoperative or postoperative complications were observed. Conclusions: Laparoscopic adrenalectomy is a safe alternative to open surgery and is preferred for most patients because of shorter postoperative hospital stay and less postoperative discomfort.

    During the last two years, reports on laparoscopic procedures of the pancreas have been on increase. Laparoscopic resection of the pancreatic cauda is indicated, primarily, for benign cystic lesions of the cauda of the pancreas and for neuroendocrine tumors of the pancreas (mainly insulinomas). We have not recorded any report on the above procedure in the Czech literature. Therefore, in our case review, we have described laparoscopic distal resection of the pancreas with splenectomy for a pseudopapillary tumor of the pancreas.

    Laparoscopic liver resection (LLR) has undergone widespread dissemination after the first international consensus conference in 2008, and specialized centers continue to report remarkable achievements. However, little is known about the global adoption of LLR. This study aimed to illuminate geographical variances in the indications and technical aspects of LLR and to delineate the evolution of this approach worldwide. In advance of the Second International Consensus Conference in Morioka, Japan, a web-based, anonymous questionnaire comprising 46 questions, named the International Survey on Technical Aspects of Laparoscopic Liver Resection study, was sent via e-mail to the members of regional and International Hepato-Pancreato-Biliary Association offices. The results of the 13 questions concerning the global diffusion of LLR have been reported previously. Responses to the remaining 33 questions that corresponded to indications and surgical techniques used in LLR were collected and analyzed. Survey responses were received from 412 LLR surgeons in 42 countries on five continents. The majority of surgeons in North America had no restrictions on the maximum size or number of tumors to be resected laparoscopically. Likewise, >50 % of surgeons in East Asia and North America performed LLR for the postero-superior 'difficult' segments. Major resection was performed in 40 to >60 % of centers in North America, Europe, and East Asia. Donor hepatectomy was performed only in specialized centers. More than 75 % of respondents had adopted a pure laparoscopic approach. A flexible laparoscope was most commonly used in East Asia. Most surgeons used pneumoperitoneal pressure at around 9-16 mmHg. Other techniques and devices were used at the discretion of each surgeon. Indications for LLR continue to expand with some regional diversity. Surgical approaches and devices used in LLR are a matter of preference and availability, as in open liver resection.

    Laparoscopic cholecystectomy has revolutionized the surgical approach to gallbladder pathology. Since it was first introduced in France in 1987, and then subsequently in the United States in 1988, thousands of operations have been performed successfully. Less frequently, laparoscopic evaluation of the biliary ductal system, either by cholangiography or choledochoscopy, has been performed. Laparoscopic common duct exploration presents the next challenge for the biliary tract surgeon. This article reviews the author's early experience with laparoscopic biliary ductal evaluation, choledochoscopy, and removal of common duct stones. A suggested approach to ductal pathology is proposed.

    Laparoscopic hepatectomy is a standard surgical procedure. However, it is difficult to perform in patients with severe cirrhosis because of fibrosis and a high risk of hemorrhage. We report our recent experience in five cases of pure laparoscopic hepatectomy combined with a pure laparoscopic Pringle maneuver in patients with severe cirrhosis. From 2012 to 2014, we performed pure laparoscopic partial hepatectomy in five patients with severe liver cirrhosis (indocyanine green retention rate at 15 min [ICG R15] >30% and fibrosis stage f4). A pure laparoscopic Pringle maneuver was employed in all patients. We investigated operative time, blood loss, duration of hospitalization and the days when discharge was possible, and compared these findings with those of patients with a normal liver (ICG R15 <10%, f0) who underwent pure laparoscopic partial hepatectomy during the same period (n = 7). As a result, operative time, blood loss, duration of hospitalization and the days when discharge was possible were similar in patients with cirrhosis undergoing pure laparoscopic hepatectomy combined with a pure laparoscopic Pringle maneuver to those in patients with a normal liver undergoing pure laparoscopic partial hepatectomy. In conclusion, pure laparoscopic hepatectomy combined with a pure laparoscopic Pringle maneuver appears to be safe in patients with severe cirrhosis.

    Spigelian hernia (SH) is an uncommon abdominal wall hernia. Its clinical symptoms are not characteristic, and the preoperative diagnosis is often difficult because SH can simulate the symptoms of more classical lower quadrant abdominal diseases. We report a case of SH in an 80-year-old woman that was complicated by incarceration and diagnosed by physical examination and ultrasound. At the time of presentation, she had an abdominal mass that was soft and occasionally painful, and aggravated by movements that increase intraabdominal pressure. Laparoscopic examination of the abdominal cavity identified the incarcerate jejunum ansae. The defect was a large opening in the peritoneum along the lateral margin of the rectus abdominis muscle. After dissection of the intestinal adhesions, a prosthetic polypropylene mesh was introduced and fixed with staples into the lateral abdominal wall. There were no postoperative complications. We conclude that the laparoscopic approach is a feasible alternative to the conventional open technique that is easy, safe, and allows excellent operative visualization.

    The authors report a case of idiopathic retroperitoneal fibrosis (RPF) in a 38-year-old man presenting with obstructive acute renal failure. The initial management consisted of urinary diversion by bilateral double-J ureteric stenting. After restoration of normal renal function, CT urography demonstrated retroperitoneal fibrosis surrounding the two ureters. Surgical treatment was performed by laparoscopy using four trocars. The operation consisted of detachment of the ascending and descending colon followed by release of the ureters from the lumbar segment to the pelvic segment and finally intraperitonealization of the ureters. The operating time was six hours, the postoperative course was uneventful and the double-J stents were removed at the third week. Laparoscopic treatment of RPF is a treatment option providing all of the benefits of minimally invasive surgery. In the light of this case and a review of the literature, the authors describe the laparoscopic treatment of idiopathic retroperitoneal fibrosis.

    The objectives of this study were to evaluate and compare the performance of the deceased donor registries of the 50 states and the District of Columbia and to identify possible predictive factors of donor designation. Data were collected retrospectively by Donate Life America using a questionnaire sent to Donor Designation Collaborative state teams between 2007 and 2010. By the end of 2010, there were 94,669,081 designated donors nationwide. This accounted for 39.8 per cent of the U.S. population aged 18 years and over. The number of designated organ donors and registry-authorized recovered donors increased each year; however, the total number of recovered donors in 2010 was the lowest since 2004. Donor designation rate was significantly higher when license applicants were verbally questioned at the Department of Motor Vehicles (DMV) regarding their willingness to register as a donor and when DMV applicants were not given an option on DMV application forms to contribute money to support organ donation, compared with not being questioned verbally, and being offered an option to contribute money. State registries continue to increase the total number of designated organ donors; however, the current availability of organs remains insufficient to meet the demand. These data suggest that DMV applicants who are approached verbally regarding their willingness to register as a donor and not given an option on DMV application forms to contribute money to support organ donation might be more likely to designate themselves to be a donor.

    Cholangiography does not prevent bile duct injury, but if performed properly, it can identify impending injury before hand. We present a modified form of laparoscopic cholecystcholangiography; only 5 min are required to perform this technique. Some 408 consecutive peroperative cholangiographies are analyzed. We recommend this method, which decreases the risk of bile duct injuries, reveals occult bile duct stones in 4.2%, and gives the opportunity to approximate the gold standard of cholecystectomies.

    Background and Objectives: The mobile cecum is an embryologic abnormality and has been associated with functional colon disease (chronic constipation and irritable bowel syndrome). However, unlike functional disease, the primary treatment is operative, using laparoscopic cecopexy. We compare the epidemiology and pathophysiology of mobile cecum syndrome and functional colon disease and propose diagnostic and treatment guidelines. Method: This study was a case–control series of 15 patients who underwent laparoscopic cecopexy. Age, gender, recurrent abdominal pain, and constipation based on Rome III criteria were assessed. Ileocecal–appendiceal unit displacement was graded as follows: I (cecum retroperitoneal or with little mobility); II (wide mobility, crossing the midline); and III (maximum mobility, reaching the left abdomen). Patients with Grades II and III underwent laparoscopic cecopexy. The clinical outcomes were evaluated according to modified Visick's criteria, and postoperative complications were assessed according to the Clavien-Dindo classification. Results: The mean age was 31.86 ± 12.02 years, and 13 patients (86.7%) were women. Symptoms of constipation and abdominal pain were present in 14 (93.3%) and 11 (73.3%), respectively. Computed tomography was performed in 8 (53.3%) patients. The mean operative time was 41 ± 6.66 min. There were no postoperative infections. One (7.8%) patient was classified as Clavien Dindo IIIb and all patients were classified as Visick 1 or 2. Conclusion: Many patients with clinical and epidemiological features of functional colon disease in common in fact have an anatomic anomaly, for which the treatment of choice is laparoscopic cecopexy. New protocols should be developed to support this recommendation. PMID:27807396

    Rudow, Dianne LaPointe; Brown, Robert S

    2003-06-01

    As a result of the cadaveric organ shortage, the number of centers performing living donor liver transplantation has increased. Living donor liver transplantation provides immediate organ availability and avoids the risk of life-threatening complications that occur with long waiting times for cadaveric organs; however, it puts a healthy person at risk for little personal gain. A standardized approach to donor evaluation ensures safety to potential donors. Careful medical (physical examination as well as laboratory and radiological evaluation) and psychological evaluation is imperative to reduce donor complications and ensure good outcomes in recipients. A social worker and psychiatrist assess for mental competency, provide emotional support, and can serve as independent donor advocates. Informed understanding and consent are crucial aspects of the evaluation and include ensuring that the donor understands all potential complications and is free of coercion. Safety of the donor must be the highest priority.

    2016-10-01

    The substantial evidence of the safety of human leukocyte antigen (HLA)-haploidentical (haplo) blood or marrow transplantation (BMT) has led to its increasing utilization. When prioritizing HLA-matched grafts, patients frequently have few or no donors from whom to choose. However, a given patient may have multiple suitable haplo donors. Therefore factors other than HLA-match become critical for selecting the best donor. We recommend a donor selection algorithm based on the donor-specific antibodies, ABO match, donor age, donor sex, and cytomegalovirus (CMV) serostatus match. Despite provocative initial evidence, further studies are warranted to determine whether there is any benefit to selecting a haplo donor based on the number of HLA-mismatches, natural killer cell alloreactivity, or the presence of non-inherited maternal HLA antigens.

    Introduction Pectopexy, a laparoscopic method for prolapse surgery, showed promising results in recent literature. Further improving this approach by reducing surgical time may decrease complication rates and patient morbidity. Since laparoscopic suturing is a time consuming task, we propose a single suture /mesh ileo-pectineal ligament fixation as opposed to the commonly used continues approach. Methods Evaluation was performed on human non-embalmed, fresh cadaver pelves. A total of 33 trials was performed. Eight female pelves with an average age of 75, were used. This resulted in 16 available ligaments. Recorded parameters were ultimate load, displacement at failure and stiffness. Results The ultimate load for the mesh + simplified single “interrupted” suture (MIS) group was 35 (± 12) N and 48 (± 7) N for the mesh + continuous suture (MCS) group. There was no significant difference in the ultimate load between both groups (p> 0.05). This was also true for displacement at failure measured at 37 (± 12) mm and 36 (±5) mm respectively. There was also no significant difference in stiffness and failure modes. Conclusion Given the data above we must conclude that a continuous suture is not necessary in laparoscopic mesh / ileo-pectineal ligament fixation during pectopexy. Ultimate load and displacement at failure results clearly indicate that a single suture is not inferior to a continuous approach. The use of two single sutures may improve ligamental fixation. However, overall stability should not benefit since the surgical mesh remains the limiting factor. PMID:26844890

    Laparoscopic gastric plication is an emerging restrictive bariatric procedure but still lacks standardization of the technique. The aim of this study was to apply a standardized, modified 3-port approach to laparoscopic gastric plication to improve outcomes. The modified laparoscopic gastric plication technique was applied for 63 morbidly obese patients between March 2010 and January 2013. There were 9 men and 54 women, with a mean age of 34.2 years (range 20-48 years) and a mean body mass index of 38.9 kg/m(2) (range 32-65 kg/m(2)). There were no deaths, no conversion to laparotomy, no reoperation, and no readmission. Percent excess weight loss was 41%, 52%, and 60% at 3, 6, and 12 months, respectively. There were no major complications reported in our study, but prolonged early postoperative nausea and vomiting occurred in 3 of 63 (4.8%) patients who had been successfully treated with proton pump inhibitors and antiemetics. Our initial experience showed that the 4-bite technique starting 2 cm below the angle of His with tight calibration of the gastric tube for obese patients is feasible, effective, and well tolerated, with a low frequency of major problems.

  18. Review. Laparoscopic appendicectomy: current status.

    PubMed Central

    Memon, M. A.

    1997-01-01

    Laparoscopic appendicectomy (LA), has failed to gain unequivocal acceptance by the general surgical community as an alternative to open appendicectomy (OA). This is because the early postoperative recovery leading to quicker hospital discharge, which led to the worldwide acceptance of laparoscopic cholecystectomy, has not been universally seen with LA. Moreover, in the majority of the published series of LAs, there seems to be a trend towards an increased incidence of intra-abdominal abscesses. However, laparoscopy is superior to the 'watch and wait' policy where the diagnosis of appendicitis is questionable. Furthermore, since a large incision can be avoided by using the LA technique in obese patients, the incidence of postoperative morbidity can be reduced considerably. Nevertheless, before endorsing routine and widespread use of LA, it is essential that this technique is critically evaluated in well-designed, controlled, randomised trials, showing clearly the major benefits to the patient in terms of quicker hospital discharge, reduced postoperative pain, decreased wound infection and early return to full activities. Laparoscopic appendicectomy will never replace all open appendicectomies, but should become an alternative in certain groups of patients. PMID:9422862

    As there is no precise laboratory test or imaging study for detection of pancreas allograft rejection, there is increasing interest in obtaining pancreas tissue for diagnosis. Pancreas allograft biopsies are most commonly performed percutaneously, transcystoscopically, or endoscopically, yet pancreas transplant surgeons often lack the skills to perform these types of biopsies. We have performed 160 laparoscopic pancreas biopsies in 95 patients. There were 146 simultaneous kidney-pancreas biopsies and 14 pancreas-only biopsies due to pancreas alone, kidney loss, or extraperitoneal kidney. Biopsies were performed for graft dysfunction (89) or per protocol (71). In 13 cases, an additional laparoscopic procedure was performed at the same operation. The pancreas diagnostic tissue yield was 91.2%; however, the pancreas could not be visualized in eight cases (5%) and in 6 cases the tissue sample was nondiagnostic (3.8%). The kidney tissue yield was 98.6%. There were four patients with intraoperative complications requiring laparotomy (2.5%) with two additional postoperative complications. Half of all these complications were kidney related. There were no episodes of pancreatic enzyme leak and there were no graft losses related to the procedure. We conclude that laparoscopic kidney and pancreas allograft biopsies can be safely performed with very high tissue yields. © 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.

  20. A novel method of minimally invasive rectus abdominis muscle flap harvest: Laparoscopic surgeons take note

    The rectus abdominis muscle (RAM) is a workhorse flap to fill or repair abdominal defects. A drawback of an open RAM harvest is donor site morbidity, and minimally invasive techniques for flap harvesting have been previously proposed but involve vertical division of the rectus fascia. We present a case of a 52-year-old woman with a recurrent rectovaginal fistula in a radiated field treated with a laparoscopic low anterior resection with simultaneous RAM flap harvest utilising a single Pfannenstiel incision. Our novel modified laparoscopic-assisted RAM harvest technique prevents longitudinal violation of the anterior and posterior rectus sheaths, thereby promoting a quick recovery, improved cosmesis and decreased post-operative morbidity.

    Colostomy prolapse is a frequently seen complication of transverse colostomy. In one child with recurrent stoma prolapse, we performed a loop-to-loop fixation and peritoneal tethering laparoscopically. No prolapse had recurred at follow-up. Laparoscopic repair of transverse colostomy prolapse seems to be a less invasive method than other techniques.

  7. Complications of donor apheresis.

    PubMed

    Winters, Jeffrey L

    2006-07-01

    A decreasing blood donor pool in the presence of increasing blood transfusion demands has resulted in the need to maximally utilize each blood donor. This has led to a trend in the increasing use of automated blood collections. While apheresis donation shares many reactions and injuries with whole blood donation, because of the differences, unique complications also exist. Overall, evidence in the literature suggests that the frequency of reactions to apheresis donation is less than that seen in whole blood donation, though the risk of reactions requiring hospitalization is substantially greater. The most common apheresis-specific reaction is hypocalcemia due to citrate anticoagulation, which, while usually mild, has the potential for severely injuring the donor. Other reactions to apheresis donation are uncommon (e.g., hypotension) or rare (e.g., air embolism). More worrisome, and in need of additional study, are the long-term effects of apheresis donation. Recent evidence suggests that repeated apheresis platelet donations may adversely effect thrombopoiesis as well as bone mineralization. Granulocyte donation has also been implicated in unexpected long-term consequences.

    Objective: To present an analysis of our experience with 22 consecutive cases of acute abdominal gynecologic emergencies managed with a laparoscopic approach. Methods: From March 1997 to October 1998, 22 patients with a diagnosis of acute abdominal gynecologic emergencies underwent laparoscopic intervention. A transvaginal ultrasound was performed on all patients preoperatively to supplement the diagnostic workup. Surgical time, complications, and length of hospital stay were evaluated, and the laparoscopic diagnosis was compared with the preoperative diagnosis. Results: The laparoscopic diagnosis was different from the preoperative diagnosis in 31.8% of patients. Of the 22 patients, laparoscopic therapeutic procedures were performed in 18 (81.8%), all satisfactorily, and with no need for conversion to open surgery. No morbidity or mortality occurred. Conclusion: Laparoscopy is a safe and effective method for diagnosing and treating gynecologic emergencies. PMID:14558712

    AIM: To structure the rate of intraoperative complications that requires an intraoperative or perioperative resolution. METHODS: We perform a literature review of Medline database. The research was focused on intraoperative laparoscopic procedures inside the field of urological oncology. General rate of perioperative complications in laparoscopic urologic surgery is described to be around 12.4%. Most of the manuscripts published do not make differences between pure intraoperative, intraoperative with postoperative consequences and postoperative complications. RESULTS: We expose a narrative statement of complications, possible solutions and possible preventions for most frequent retroperitoneal and pelvic laparoscopic surgery. We expose the results with the following order: retroperitoneal laparoscopic surgery (radical nephrectomy, partial nephrectomy, nephroureterectomy and adrenalectomy) and pelvic laparoscopic surgery (radical prostatectomy and radical cystectomy). CONCLUSION: Intraoperative complications vary from different series. More scheduled reports should be done in order to better understand the real rates of complications. PMID:25984519

    To evaluate the role of ALA induced fluorescence diagnosis in laparoscopic surgery, we induced peritoneal carcinosis in rats by multilocular intraabdominal tumorcell implantation (CC531). The animals were photosensitized by intraabdominal ALA lavage. Laparoscopy was performed with both, conventional white and then blue light (D-Light, KARL STORZ Germany) excitation. Laparoscopy with conventional white light showed peritoneal carcinoma foci from 0.1 to 2 cm in diameter. All macroscopically visible tumors (n equals 142) were fluorescence positive after laparoscopic blue light excitation. In addition, 30 laparoscopic not visible (white light) tumors showed fluorescence and were histologically confirmed as colon carcinoma metastases. We conclude that only ALA induced laparoscopic fluorescence detection after blue light excitation is the adequate method to detect the entire extent of the intraabdominal tumor spread. Fluorescence laparoscopy is essential for laparoscopic staging of colorectal cancer because of a higher rate of cancer foci detection.

  12. Do laparoscopic skills transfer to robotic surgery?

    2014-03-01

    Identifying the set of skills that can transfer from laparoscopic to robotic surgery is an important consideration in designing optimal training curricula. We tested the degree to which laparoscopic skills transfer to a robotic platform. Fourteen medical students and 14 surgery residents with no previous robotic but varying degrees of laparoscopic experience were studied. Three fundamentals of laparoscopic surgery tasks were used on the laparoscopic box trainer and then the da Vinci robot: peg transfer (PT), circle cutting (CC), and intracorporeal suturing (IS). A questionnaire was administered for assessing subjects' comfort level with each task. Standard fundamentals of laparoscopic surgery scoring metric were used and higher scores indicate a superior performance. For the group, PT and CC scores were similar between robotic and laparoscopic modalities (90 versus 90 and 52 versus 47; P > 0.05). However, for the advanced IS task, robotic-IS scores were significantly higher than laparoscopic-IS (80 versus 53; P < 0.001). Subgroup analysis of senior residents revealed a lower robotic-PT score when compared with laparoscopic-PT (92 versus 105; P < 0.05). Scores for CC and IS were similar in this subgroup (64 ± 9 versus 69 ± 15 and 95 ± 3 versus 92 ± 10; P > 0.05). The robot was favored over laparoscopy for all drills (PT, 66.7%; CC, 88.9%; IS, 94.4%). For simple tasks, participants with preexisting skills perform worse with the robot. However, with increasing task difficulty, robotic performance is equal or better than laparoscopy. Laparoscopic skills appear to readily transfer to a robotic platform, and difficult tasks such as IS are actually enhanced, even in subjects naive to the technology. Copyright © 2014 Elsevier Inc.

    Purpose The ideal treatment for choledocholithiasis should be simple, readily available, reliable, minimally invasive and cost-effective for patients. We performed this study to compare the benefits and drawbacks of different laparoscopic approaches (transcystic and choledochotomy) for removal of common bile duct stones. Methods A systematic search was implemented for relevant literature using Cochrane, PubMed, Ovid Medline, EMBASE and Wanfang databases. Both the fixed-effects and random-effects models were used to calculate the odds ratio (OR) or the mean difference (MD) with 95% confidence interval (CI) for this study. Results The meta-analysis included 18 trials involving 2,782 patients. There were no statistically significant differences between laparoscopic choledochotomy for common bile duct exploration (LCCBDE) (n = 1,222) and laparoscopic transcystic common bile duct exploration (LTCBDE) (n = 1,560) regarding stone clearance (OR 0.73, 95% CI 0.50–1.07; P = 0.11), conversion to other procedures (OR 0.62, 95% CI 0.21–1.79; P = 0.38), total morbidity (OR 1.65, 95% CI 0.92–2.96; P = 0.09), operative time (MD 12.34, 95% CI −0.10–24.78; P = 0.05), and blood loss (MD 1.95, 95% CI −9.56–13.46; P = 0.74). However, the LTCBDE group showed significantly better results for biliary morbidity (OR 4.25, 95% CI 2.30–7.85; P<0.001), hospital stay (MD 2.52, 95% CI 1.29–3.75; P<0.001), and hospital expenses (MD 0.30, 95% CI 0.23–0.37; P<0.001) than the LCCBDE group. Conclusions LTCBDE is safer than LCCBDE, and is the ideal treatment for common bile duct stones. PMID:27668730

    Summary Despite a steady increase in total blood collections and voluntary non-remunerated blood donors, China continues to have many challenges with its blood donation system. The country's donation rate remains low at 9%o, with over 60% of donors being first-time donors. Generally there is a lack of adequate public awareness about blood donation. The conservative donor selection criteria, the relatively long donation interval, and the small donation volume have further limited blood supply. To ensure a sufficient and safe blood supply that meets the increasing clinical need for blood products, there is an urgent need to strengthen the country's blood donor management. This comprehensive effort should include educating and motivating more individuals especially from the rural areas to be involved in blood donation, developing rational and evidence-based selection criteria for donor eligibility, designing a donor follow-up mechanism to encourage more future donations, assessing the current donor testing strategy, improving donor service and care, building regional and national shared donor deferral database, and enhancing the transparency of the blood donation system to gain more trust from the general public. The purpose of the review is to provide an overview of the key process of and challenges with the blood donor management system in China. PMID:25254023

    The aim of this study was to determine the clinical effectiveness and cost-effectiveness of laparoscopic, laparoscopically assisted (hereafter together described as laparoscopic surgery) and hand-assisted laparoscopic surgery (HALS) in comparison with open surgery for the treatment of colorectal cancer. Electronic databases were searched from 2000 to May 2005. A review of economic evaluations was undertaken by the National Institute for Health and Clinical Excellence in 2001. This review was updated from 2000 until July 2005. Data from selected studies were extracted and assessed. Dichotomous outcome data from individual trials were combined using the relative risk method and continuous outcomes were combined using the Mantel-Haenszel weighted mean difference method. Summaries of the results from individual patient data (IPD) meta-analyses were also presented. An economic evaluation was also carried out using a Markov model incorporating the data from the systematic review. The results were first presented as a balance sheet for comparison of the surgical techniques. It was then used to estimate cost-effectiveness measured in terms of incremental cost per life-year gained and incremental cost per quality-adjusted life-year (QALY) for a time horizon up to 25 years. Forty-six reports on 20 studies [19 randomised controlled trials (RCTs) and one IPD meta-analysis] were included in the review of clinical effectiveness. The RCTs were of generally moderate quality with the number of participants varying between 16 and 1082, with 10 having less than 100 participants. The total numbers of trial participants who underwent laparoscopic or open surgery were 2429 and 2139, respectively. A systematic review of four papers suggested that laparoscopic surgery is more costly than open surgery. However, the data they provided on effectiveness was poorer than the evidence from the review of effectiveness. The estimates from the systematic review of clinical effectiveness were

    This prospective study describes a simple method of combining laparoscopic ovariectomy and laparoscopic-assisted prophylactic gastropexy and determines the duration of surgery, complications, and long-term outcome including prevention of gastric dilatation-volvulus (GDV). Laparoscopic ovariectomy and laparoscopic-assisted gastropexy were performed on 26 sexually intact female dogs susceptible to GDV. The mean surgery time was 60.8 ± 12.4 min. No GDV episode was seen during the study period (mean follow-up: 5.2 ± 1.4 y). All dogs had an intact gastropexy attachment assessed by ultrasonography at 1 y. Post-operative complications were minor and owners were satisfied with the procedure. Combined laparoscopic ovariectomy and laparoscopic- assisted gastropexy appears to be a successful and low morbidity alternative procedure to both ovariectomy/ovariohysterectomy and gastropexy via open ventral-midline laparotomy.

    GENERAL: A force sensor has been designed and fabricated that will fit to existing laparoscopic grasping forceps (Babcocks) from Ethicon Endosurgery Inc. The goal of the sensor development is to provide tool-tissue force information to the surgeons so that surgeons can regain the sense of touch that has been lost through laparoscopy. Eventually, force sensing will provide feedback for robotic laparoscopic surgical platforms. We have developed a prototype force sensor system with ATI Industrial Automation. This tool is provided as an in-line transducer with six degrees of freedom that can retrofit current Babcocks. The sensor is currently being used in clinical trials with animals to determine the benefits. The sensor system utilizes industry proven technology in combination with a custom transducer and user interface. A GUI is part of the system and provides resolved force magnitude data in a graphical format for case of interpretation. Sterilization, size, and ease of use are addressed by the current design. Operating room reliability and safety are currently being investigated. A three phase experimental trial using a porcine model is being completed that will test the hypothesis that force information can be used to minimize tissue trauma during laparoscopic surgery. Based on our research, there is strong evidence that surgeons would benefit from information regarding the levels of force applied to tissues. In the future, robotic surgery will require force sensing. Surgical simulators could provide force feedback during simulated surgical procedures by using a sensor platform such as this. In addition, tool tip design in the future will benefit from the application of this technology and data base.

    AIM: To retrospective review the laparoscopic management of Meckel Diverticulum (MD) in two Italian Pediatric Surgery Centers. METHODS: Between January 2002 and December 2012, 19 trans-umbilical laparoscopic-assisted (TULA) procedures were performed for suspected MD. The children were hospitalized for gastrointestinal bleeding and/or recurrent abdominal pain. Median age at diagnosis was 5.4 years (range 6 mo-15 years). The study included 15 boys and 4 girls. All patients underwent clinical examination, routine laboratory tests, abdominal ultrasound and technetium-99m pertechnetate scan, and patients with bleeding underwent gastrointestinal endoscopy. The abdominal exploration was performed with a 10 mm operative laparoscope. Pneumoperitoneum was established based on the body weight. Systematic overview of the peritoneal cavity allowed the ileum to be grasped with an atraumatic instrument. The complete exploration and surgical treatment of MD were performed extracorporeally, after intestinal exteriorization through the umbilicus. All patients’ demographics, main clinical features, diagnostic investigations, operative time, histopathology reports, conversion rate, hospital stay and complications were registered and analyzed. RESULTS: MD was identified in 17 patients, while 1 had an ileal duplication and 1 a jejunal hemangioma. Fifteen patients had painless intestinal bleeding, while 4 had recurrent abdominal pain and exhibited cyst like structures in an ultrasound study. Eleven patients had a positive technetium-99m pertechnetate scan. In the patients with bleeding, gastrointestinal endoscopy did not name the source of hemorrhage. All patients were subjected to a TULA surgical procedure. An intestinal resection/anastomosis was performed in 14 patients, while 4 had a wedge resection of the diverticulum and 1 underwent stapling diverticulectomy. All surgical procedures were performed without conversion to open laparotomy. Mean operative time was 75 min (range 40

    Objectives: To compare the incidence of perioperative complications and postoperative healthcare utilization and costs in laparoscopic supracervical hysterectomy (LSH) versus laparoscopic-assisted vaginal hysterectomy (LAVH) patients. Methods: Women ≥18 years with LSH or LAVH were extracted using a large national commercial claims database from 1/1/2007 through 9/30/2008. Outcome was perioperative complications and gynecologic-related postoperative resource use and costs. Multivariate analysis was performed to compare postsurgical outcomes between the cohorts. Results: The final sample consisted of 6,198 LSH patients and 14,181 LAVH patients. LSH patients were significantly more likely to have dysfunctional uterine bleeding and leiomyomas and less likely to have endometriosis and prolapse as the primary diagnosis, and also significantly more likely to have a uterus that weighed >250 grams than LAVH patients. Compared with LAVH patients, LSH patients had significantly lower overall infection rates (7.4% versus 6.2%, P=.002) and lower total gynecologic-related postoperative costs ($252 versus $385, P<.001, within 30 days of follow-up and $350 versus $569, P<.001, within 180 days of follow-up). Significant cost differences remained following multivariate adjustment for patient characteristics. Conclusions: LSH patients demonstrated fewer perioperative complications and lower GYN-related postoperative costs compared to LAVH patients. PMID:22643499

This cohort study was designed to directly compare perioperative outcomes of the left lateral segmentectomy via laparoscopic and open approach. Methods Between 2002 and 2006 43 left lateral segmentectomies were performed at King's College Hospital. Those excluded from analysis included previous liver resections, polycystic liver disease, liver cirrhosis and synchronous operations. Of 20 patients analysed, laparoscopic (n = 10) were compared with open left lateral segmentectomy (n = 10). Both groups had similar patient characteristics. Results Morbidity rates were similar with no wound or chest infection in either group. The conversion rate was 10% (1/10). There was no difference in operating time between the groups (median time 220 minutes versus 179 minutes, p = 0.315). Surgical margins for all lesions were clear. Less postoperative opiate analgesics were required in the laparoscopic group (median 2 days versus 5 days, p = 0.005). The median postoperative in-hospital stay was less in the laparoscopic group (6 days vs 9 days, p = 0.005). There was no mortality. Conclusion Laparoscopic left lateral segmentectomy is safe and feasible. Laparoscopic patients may benefit from requiring less postoperative opiate analgesia and a shorter post-operative in-hospital stay. PMID:19735573

    Short bowel syndrome (SBS) is a potential postoperative complication after intra-abdominal procedures. Whether the laparoscopic approach is as likely to result in SBS or the causative mechanisms are similar to open procedures is unknown. Our aim was to evaluate potential mechanisms of SBS after laparoscopic procedures. The records of 175 adult patients developing SBS as a postoperative complication were reviewed. One hundred forty-seven patients had open procedures and 28 laparoscopic. Colectomy (39%), hysterectomy (11%), and appendectomy (11%) were the most common open procedures. SBS followed laparoscopic gastric bypass (46%) and cholecystectomy (32%) most frequently. The mechanisms of SBS were different: adhesive obstruction (57 vs 22%, P < 0.05) was more common in the open group, whereas volvulus (18 vs 46%, P < 0.05) was more common after laparoscopy. Overall, ischemia (25 vs 32%) was similar but significantly more laparoscopic patients had postoperative hypoperfusion (32 vs 67%, P < 0.05). Eleven of the 13 laparoscopic bariatric procedures had internal hernias and volvulus. Of the nine patients undergoing cholecystectomy, four developed ischemia early postoperatively presumably secondary to pneumoperitoneum. SBS is an increasingly recognized complication of laparoscopic procedures. The mechanisms of intestinal injury differ from open procedures with a higher incidence of volvulus and more frequent ischemia from hypoperfusion.

    Between 2010 and 2016, 110 patients with extremity lymphedema underwent vascularized lymph node (VLN) transfer: groin (G-VLN = 20), supraclavicular (SC-VLN = 54), and right gastroepiploic (RGE-VLN = 36) open and laparoscopic approach. Herein, we discuss the pearls and pitfalls for VLN harvest and compare donor site morbidity and complications. Lymphatic leakage: G-VLN (n = 1) and SC-VLN (n = 1) and one hematoma: SC-VLN were found. Laparoscopic harvest of the RGE-VLN reduces donor site morbidity. However, surgeons experience is imperative to minimize donor site morbidity and complications. J. Surg.

    Laparoscopic donor nephrectomy (LDN) is well established; however, there is concern about early graft loss because of technical issues with right-sided LDN. Prior studies on the subject were mostly single centered and not powered to detect clinically significant differences in allograft failure. We conducted a retrospective cohort study of recipients of live donor kidney transplants using national registry data. The primary endpoint was 90-day allograft failure. Multivariable logistic regression analyses were stratified as overall live donor transplantation, transplantation after LDN, and transplantation after open donor nephrectomy (ODN). Between 2001 and 2006, a total of 2555 right LDNs, 25,387 left LDNs, 2496 right ODNs, and 5552 left ODNs were performed. For the entire cohort compared with ODN, LDN was not associated with early allograft loss (odds ratio [OR]=0.94, P=0.4); however, right-sided nephrectomy increased the risk of allograft loss (OR=1.49, P<0.01). When stratified by procedure type, right LDN (OR=1.58, P<0.01) and right ODN (OR=1.38, P=0.02) demonstrated an association with increased risk of graft failure compared with the left side. The observed risk of allograft failure with right-sided LDN was 3.8% vs. 2.5% with left-sided LDN. Right-sided donor nephrectomy is associated with a small increased risk of allograft failure regardless of open or laparoscopic approach. However, the low observed risk of allograft failure with right-sided nephrectomy suggests that recovering the right kidney is a reasonable option for donors with contraindications for donating the left kidney.

    Background Laparoscopic cholecystectomy has traditionally been performed with four incisions to insert four trocars, in a simple, efficient and safe way. Aim To describe a simplified technique of laparoscopic cholecystectomy with two incisions, using basic conventional instrumental. Technique In one incision in the umbilicus are applied two trocars and in epigastrium one more. The use of two trocars on the same incision, working in "x" does not hinder the procedure and does not require special instruments. Conclusion Simplified laparoscopic cholecystectomy with two incisions is feasible and easy to perform, allowing to operate with ergonomy and safety, with good cosmetic result. PMID:25004296

    Port site wound infection, abdominal wall hematoma and intraabdominal abscess formation has been reported after laparoscopic appendicectomy. We describe here a rectus sheath abscess which occurred three weeks after the laparoscopic appendicectomy. It was most likely the result of secondary infection of the rectus sheath hematoma due to bleeding into the rectus sheath from damage to the inferior epigastric arteries or a direct tear of the rectus muscle. As far as we are aware this complication has not been reported after laparoscopic appendicectomy. PMID:21124654

    In our initial experience with 82 patients, laparoscopic cholecystectomy has shown numerous advantages over open cholecystectomy. Both intraoperative blood loss and postoperative need for pain medication have been minimal. Most patients were discharged within 24 to 36 hours and resumed normal activities within 3 to 5 days. The aesthetic aspect is also an obvious advantage, since the laparoscopic procedure avoids disfiguring abdominal scars. Previous abdominal surgery is not a contraindication to attempting this procedure. Based on our experience, laparoscopic cholecystectomy can be done safely on most patients who are candidates for open cholecystectomy, including the elderly, the obese, and those with acute gangrenous cholecystitis.

    Single-incision laparoscopic surgery is an alternative to conventional multiport laparoscopy. Single-access laparoscopy using a transumbilical port affords maximum cosmetic benefits because the surgical incision is hidden in the umbilicus. The advantages of single-access laparoscopic surgery may include less bleeding, infection, and hernia formation and better cosmetic outcome and less pain. The disadvantages and limitations include longer surgery time, difficulty in learning the technique, and the need for specialized instruments. Ongoing refinement of the surgical technique and instrumentation is likely to expand its role in gynecologic surgery in the future. We perform single-incision total laparoscopic hysterectomy using three ports in the single transumbilical incision.

    In the Essen University Clinic for Psychotherapy and Psychosomatics, between January and December 2000, 54 potential liver donors and 12 kidney donors were examined. All the kidney donors were found to be suitable; 7 potential liver donors were rejected on psychosomatic grounds. Reasons for the rejection were addiction (1 donor), suspected financial dependency of the donor on the recipient (1 donor) and, in the case of one donor not related to the recipient, the apparent lack of a special emotional attachment. During the actual evaluation interview, 4 potential donors reversed their original decision. Such a psychosomatic evaluation is a great help for donors in clarifying their motives and their decision.

    The technology that has permitted the rapid advance of minimal access surgery has now made it feasible to perform laparoscopically assisted colon resections safely. As the instrumentation improves, specimen removal problems are solved, surgeons' sewing skills improve, and other anastomotic methods are devised, an increasing amount of colonic surgery will be done using laparoscopy. It is clear that the techniques now in use are evolving, and will be substantially different a few years hence. Previously accepted surgical principles may continue to be challenged by new techniques, which must be evaluated under strict protocol before being widely accepted. These operations should be performed by surgeons who are able to achieve the same level of radical operation that they would achieve through a laparotomy. Special training in advanced laparoscopic techniques including microsurgical suturing is a distinct advantage in performing these operations successfully. It may be best for surgeons to start with palliative procedures or operations for benign diseases of the colon, to avoid the risk of jeopardizing an operation for cancer.

    Background and Objectives: To analyze the frequency of complications during laparoscopic gynecologic surgery and identify associated risk factors. Methods: A descriptive observational study was performed between January 2000 and December 2012 and included all gynecologic laparoscopies performed at our center. Variables were recorded for patient characteristics, indication for surgery, length of hospital stay (in days), major and minor complications, and conversions to laparotomy. To identify risk factors and variables associated with complications, crude and adjusted odds ratios were calculated with unconditional logistic regression. Results: Of all 2888 laparoscopies included, most were procedures of moderate difficulty (adnexal surgery) (54.2%). The overall frequency of major complications was 1.93%, and that of minor complications was 4.29%. The level of technical difficulty and existence of prior abdominal surgery were associated with a higher risk of major complications and conversions to laparotomy. Conclusion: Laparoscopic gynecologic surgery is associated with a low frequency of complications but is a procedure that is not without risk. Greater technical difficulty and prior surgery were factors associated with a higher frequency of complications. PMID:25392659

    Laparoscopic cholecystectomy (key-hole removal of the gallbladder) is now the most often used method for treatment of symptomatic gallstones. Several cardiopulmonary changes (decreased cardiac output, pulmonary compliance, and increased peak airway pressure) occur during pneumoperitoneum, which is now introduced to allow laparoscopic cholecystectomy. These cardiopulmonary changes may not be tolerated in individuals with poor cardiopulmonary reserve. To assess the benefits and harms of abdominal wall lift compared to pneumoperitoneum in patients undergoing laparoscopic cholecystectomy. We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE, and Science Citation Index Expanded until February 2013. We included all randomised clinical trials comparing abdominal wall lift (with or without pneumoperitoneum) versus pneumoperitoneum. We calculated the risk ratio (RR), rate ratio (RaR), or mean difference (MD) with 95% confidence intervals (CI) based on intention-to-treat analysis with both the fixed-effect and the random-effects models using the Review Manager (RevMan) software. For abdominal wall lift with pneumoperitoneum versus pneumoperitoneum, a total of 130 participants (all with low anaesthetic risk) scheduled for elective laparoscopic cholecystectomy were randomised in five trials to abdominal wall lift with pneumoperitoneum (n = 53) versus pneumoperitoneum only (n = 52). One trial which included 25 people did not state the number of participants in each group. All five trials had a high risk of bias. There was no mortality or conversion to open cholecystectomy in any of the participants in the trials that reported these outcomes.

    The safety of transfusion is still improving and very important is raising of education among donors. The important element is also awareness of the possibility of withdrawing themselves from the donation process when they know that their blood isn't suitable for recipients. The aim of this study was checked of donor's knowledge about the risk of transfusion transmitted infections. The 581 regular donors (86.2% men, mean age 32 years) who answered of questions about tests which are performed in donation, and about their knowledge of transmission infections by transfusions. Donors gave blood average four times a year, for 11 years. Over 85% of respondents believed that blood is safe. More than half of donors knew that during donation can be detected anemia, syphilis, jaundice, but 50% believed that the hepatitis viruses can be detected after one week after infection. More than 80% of donors knew about the possibility of detecting of HIV infection, but 11% written that HIV can be detected after one day after infection. Approximately 50% of donors believed that can be detected diabetes during donation, and more than 12% of them--that can be detected thyropathy and cancer. The 30% of blood donors didn't know what tests were performed in the blood donations. Donors (80%) knew about the risk groups. Donors (50%) knew correct temporary disqualification periods after surgery and tattoo also, but 17% of them indicated a shorter period of disqualification. 43% of donors shortened the time after gastroscopy. Over 30% of donors didn't know about risks of infection in case of contact with alien blood. A lot of donors (63.3%) knew about the possibility of withdrawing themselves from the donation and 43.5% of them knew about this rule. The donor doesn't need to know the details of detection of infections in blood, but donor need to know that he should be aware that even a few months is needed to obtain a reliable result, which translates into transfusion safety.

    When possible, living donor transplantation represents the best therapeutic strategy for patients suffering from chronic renal failure. Studying the donor allows a complete and thorough clinical, laboratory and instrumental assessment that guarantees good organ function whilst protecting the health of the donor. The main parameters considered within this framework are age, renal function, nephrological complications, comorbidities (diabetes, hypertension, obesity, etc.), malignancies, and infection. Moreover, particular attention is paid to the sociopsychological aspects of the donation, particularly related to the donor, the recipient, and the entire family situation.

    A best evidence topic in surgery was written according to a structured protocol. The question addressed was whether playing video games improves surgical performance in laparoscopic procedures. Altogether 142 papers were found using the reported search, of which seven represented the best evidence to answer the clinical question. The details of the papers were tabulated including relevant outcomes and study weaknesses. We conclude that medical students and experienced laparoscopic surgeons with ongoing video game experience have superior laparoscopic skills for simulated tasks in terms of time to completion, improved efficiency and fewer errors when compared to non-gaming counterparts. There is some evidence that this may be due to better psycho-motor skills in gamers, however further research would be useful to demonstrate whether there is a direct transfer of skills from laparoscopic simulators to the operating table.

    Only a few studies have revealed using laparoscopic technique with limited resection of gastrointestinal stromal tumour (GIST) of the duodenum. A 68-year-old man was admitted to the hospital due to upper gastrointestinal (GI) bleeding. Evaluation revealed an ulcerated, bleeding GI tumour in the second part of the duodenum. After control of bleeding during gastroduodenoscopy, he underwent a laparoscopic wedge resection of the area. During 1.5 years of follow-up, the patient is disease free, eats drinks well, and has regained weight. Surgical resection of duodenal GIST with free margins is the main treatment of this tumour. Various surgical treatment options have been reported. Laparoscopic resection of duodenal GIST is an advanced and challenging procedure requiring experience and good surgical technique. The laparoscopic limited resection of duodenal GIST is feasible and safe, reducing postoperative morbidity without compromising oncologic results. PMID:28281485

    Hartmann's procedure is still performed in those cases in which colorectal anastomosis might be unsafe. Reversal of Hartmann's procedure (HR) is considered a major surgical procedure with a high morbidity (55 to 60%) and mortality rate (0 to 4%). To decrease these rates, laparoscopic Hartmann's reversal procedure was successfully experienced. We report our totally laparoscopic Hartmann's reversal technique. Between 2004 and 2010 we performed 27 HRs with a totally laparoscopic approach. The efficacy and safety of this technique were demonstrated evaluating the operative data, postoperative complications, and the outcome of the patients. There were no open conversions or major intraoperative complications. Anastomotic leaking occurred in one patient requiring an ileostomy; one patient needed a blood transfusion and one had a nosocomial pneumonia. The mean postoperative hospitalization was 5.7 days. Laparoscopic HR is a feasible and safe procedure and can be considered a valid alternative to open HR.

    The author reviews his experience with the laparoscopic management of common duct pathology and compares it with the experience of others as reported in the literature. Routine intraoperative cholangiography is advocated. A variety of methods of managing common duct stones laparoscopically is presented. These include balloon-catheter manipulation, fluoroscopically guided basket extraction, and choledochoscopic evaluation and removal of stones. The accumulated experience indicates that more than 90% of common duct stones can be removed laparoscopically via the cystic duct. This approach significantly reduces the need for either preoperative or postoperative endoscopic retrograde cholangiopancreatography. Although laparoscopic choledochotomy has been employed in a number of cases and can be performed with a high degree of safety and efficacy, it is needed only infrequently. This form of management results in decreased dependence upon T-tubes, thereby reducing postoperative morbidity and the length of hospitalization. A rational protocol for the management of common duct pathology is presented.

    Although laparoscopic surgery accounts for >2 million surgical procedures every year, the current preoperative risk scores and guidelines do not adequately assess the risks of laparoscopy. In general, laparoscopic procedures have a lower risk of morbidity and mortality compared with operations requiring a midline laparotomy. During laparoscopic surgery, carbon dioxide insufflation may produce significant hemodynamic and ventilatory consequences such as increased intraabdominal pressure and hypercarbia. Hemodynamic insults secondary to increased intraabdominal pressure include increased afterload and preload and decreased cardiac output, whereas ventilatory consequences include increased airway pressures, hypercarbia, and decreased pulmonary compliance. Hemodynamic effects are accentuated in patients with cardiovascular disease such as congestive heart failure, ischemic heart disease, valvular heart disease, pulmonary hypertension, and congenital heart disease. Prevention of cardiovascular complications may be accomplished through a sound understanding of the hemodynamic and physiological consequences of laparoscopic surgery as well as a defined operative plan generated by a multidisciplinary team involving the preoperative consultant, anesthesiologist, and surgeon.

    Minimal residual disease refers to the tumour cells that are still present in a given patient after completion of a therapeutic scheme. The demonstration and quantification of residual neoplastic cells has a crucial impact in clinical decision making, for it might prompt continuation of treatment, while the absence of such cells might serve as evidence to withdraw therapy. Therefore, both sensitivity and specificity of the methods used to unravel residual neoplastic cells must be highly reliable and robust. Flow cytometry has been widely used for this purpose, and its clinical performance depends mainly on the criteria of interpretation, rather than in the technique by itself; molecular biology techniques have proved to be highly sensitive and specific but unfortunately they cannot be used in all patients or in all types of leukemia. Finally, the development of donor cell leukemia in transplanted patients, might mimic residual disease and add more confusion to an already controversial issue. These topics are discussed in this paper.

    Gallstone ileus is an uncommon cause of small bowel obstruction, occurring when one or more large gallstones erode through the gallbladder and into the intestinal lumen. The presentation is often nonspecific with intermittent symptoms, confounding diagnosis, and delaying treatment. The traditional treatment is through open enterolithotomy. Thus far only 30 of over 400 case reports on MEDLINE describe laparoscopic enterolithotomy. In this article we describe a successful total laparoscopic approach to the treatment of gallstone ileus.

    Intestinal and urinary tract involvement by endometriosis may be symptomatic, particularly when invasive disease is present. Even in expert hands, complete excision of all invasive disease cannot be accomplished laparoscopically in every case. The practitioner must balance enthusiasm for the advantages of a laparoscopic approach with limitations of time and skill. Laparoscopy should be abandoned in a particular case if a better job can be performed by laparotomy. Hysterectomy with castration may not relieve symptoms due to invasive disease.

    The aim of this systematic review was to evaluate and compare the pros and cons of using living donors or brain-dead donors in uterus transplantation programs, 2 years after the first worldwide live birth after uterus transplantation. The Medline database and the Central Cochrane Library were used to locate uterine transplantation studies carried out in human or nonhuman primates. All types of articles (case reports, original studies, meta-analyses, reviews) in English or French were considered for inclusion. Overall, 92 articles were screened and 44 were retained for review. Proof of concept for human uterine transplantation was demonstrated in 2014 with a living donor. Compared with a brain-dead donor strategy, a living donor strategy offers greater possibilities for planning surgery and also decreases cold ischemia time, potentially translating into a higher success rate. However, this approach poses ethical problems, given that the donor is exposed to surgery risks but does not derive any direct benefit. A brain-dead donor strategy is more acceptable from an ethical viewpoint, but its feasibility is currently unproven, potentially owing to a lack of compatible donors, and is associated with a longer cold ischemia time and a potentially higher rejection rate. The systematic review demonstrates that uterine transplantation is a major surgical innovation for the treatment of absolute uterine factor infertility. Living and brain-dead donor strategies are not mutually exclusive and, in view of the current scarcity of uterine grafts and the anticipated future rise in demand, both will probably be necessary.

    The aim of this study was to report our experience with the llaparoscopic transperitoneal treatment of simple renal cysts, to analyze the immediate and long-term clinical outcomes, and to evaluate the efficacy and safety of this miniinvasive surgical technique. Between 2009 and 2014 we diagnosed and treated a total of 48 patients with symptomatic simple renal cysts. The diagnosis was set up by ultrasound (US) and/or computed tomography (CT) examination. All cases were managed by transperitoneal laparoscopic cyst decortication. Demographic data, perioperative blood loss, duration of operative procedure, length of hospital stay and peri- and postoperative complications were analyzed. Follow-up included clinical examination and renal US, performed at 3-monthly intervals during the first year and yearly thereafter. Patient age ranged from 32 to 68 years (mean age 52.4 years). 27 (56.2%) of the patients were males and 21 (43.8%)--females. 42 (87.5%) of the cysts were peripheral, and 6 (12.5%)-peripelvic; 28 (58.3%) were localized to the left and 20 (41.7%)--to the right; and they ranged by size from 5 to 30 cm (mean 9.8 cm). 45 (93.8%) of the cysts were identified as category I, and only 3 (6.2%)--as category II, according to the Bosniak classification. None of the cases required conversion to open surgery. There were no peri- and postoperative complications. The average duration of the laparoscopic procedure was 55 min, and the average perioperative blood loss--50 mL. All patients had negative cytological and histological findings indicative for malignancy. The follow-up period ranged from 5 to 52ain months (average--25.4 months). In 47 cases (97.9%) exellent therapeutic results were reported: complete relief of clinical symptoms, fast recovery of physical activity and patient quality of life. There were three recurrences (6.2%) met in patients with multiple cysts, but only one of them required repeated surgery. Laparoscopic transperitoneal decortication is a

    Cholecystectomies and hernioplasties are the two most frequently performed surgical interventions. The laparoscopic technique can be offered for the simultaneous treatment with both operating indications. The synchronical operation can give all the advantages of the minimally invasive technique. Authors had performed laparoscopic cholecystectomy with laparoscopic hernioplasty in five cases. Two inguinal and three postoperative hernias were reconstructed. The cholecystectomy was performed with a "three punction method", and the hernioplasty by using the same approach, completed by inserting a fourth assisting trocar as required. The hernial ring was covered with an intraperitoneally placed mesh, which was fixed by staplers (the so-called "IPOM-method": intraperitoneal on-lay mesh). There was no intra-, nor postoperative complication. The hernioplasty combined with laparoscopic cholecystectomy did not have effect on postoperative pain and nursing time. The return to the normal physical activity was short, similar to laparoscopic hernioplasty (in 1-2 weeks). Authors conclude that the simultaneous, synchronous laparoscopic cholecystectomy and hernioplasty is recommended and should be the method of choice because it is more advantageous for patients.

    The purpose of this study is to estimate the cumulative incidence, patient characteristics, and potential risk factors for secondary hemorrhage after total laparoscopic hysterectomy. All women who underwent total laparoscopic hysterectomy at Paul's Hospital between January 2004 and April 2012 were included in the study. Patients who had bleeding per vaginam between 24 hours and 6 weeks after primary surgery were included in the analysis. A total of 1613 patients underwent total laparoscopic hysterectomy during the study period, and 21 patients had secondary hemorrhage after hysterectomy. The overall cumulative incidence of secondary hemorrhage after total laparoscopic hysterectomy was 1.3%. The mean size of the uterus was 541.4 g in the secondary hemorrhage group and 318.9 g in patients without hemorrhage, which was statistically significant. The median time interval between hysterectomy and secondary hemorrhage was 13 days. Packing was sufficient to control the bleeding in 13 patients, and 6 patients required vault suturing. Laparoscopic coagulation of the uterine artery was performed in 1 patient. Uterine artery embolization was performed twice in 1 patient to control the bleeding. Our data suggest that secondary hemorrhage is rare but may occur more often after total laparoscopic hysterectomy than after other hysterectomy approaches. Whether it is related to the application of thermal energy to tissues, which causes more tissue necrosis and devascularization than sharp culdotomy in abdominal and vaginal hysterectomies, is not clear. A large uterus size, excessive use of an energy source for the uterine artery, and culdotomy may play a role.

    We tried a new procedure of gas-less laparoscopy assisted radical nephrectomy. Prior to insertion of laparoscope, pararectal incision approximately 7 cm in length was made to enter into the intraabdominal cavity. A 12 mm trocar was placed just below the umbilicus and a flexible electroscope was inserted through it. A 10 cm size disposable fan for lifting up the abdominal wall was indwelled through the under space of trocar port. After appropriately lifting up the abdominal wall, a 10 mm trocar for working channel was placed at mid-axillar line. Under laparoscopic and trans-laparotomic views, radical nephrectomy was performed using the combined technique of laparoscopic and open surgery. Seven patients have been successfully treated with this procedure. The mean operating time of this procedure was significantly shorter than that of totally laparoscopic nephrectomy. The recovery time from the operation was as short as usual laparoscopic nephrectomy. We thought that this procedure could open a new scope of laparoscopic surgery.

    The traditional approach for the treatment of endometrial cancer by laparotomy is increasingly being replaced by laparoscopic surgery. The advantages of laparoscopy have been well-documented. Laparoscopy avoids the morbidity of a laparotomy, overcomes the limitations of vaginal hysterectomy, provides adequate pathological information for an accurate surgical staging and expedites the postoperative recovery of patients. This paper reports the outcome of a series of 50 consecutive cases of laparoscopic hysterectomy and pelvic lymphadenectomy for endometrial cancers that were performed by the author. The objective is to review the perioperative, postoperative experience and survival outcomes of patients with endometrial cancer managed by laparoscopic surgery performed by a single surgeon. The records of 50 consecutive patients with endometrial cancers from October 1995 to October 2007 treated by laparoscopic pelvic lymphadenectomy and laparoscopic hysterectomy (total and assisted) were retrospectively reviewed. Data on patients' attributes, endometrial cancers, surgical procedures, surgical complications and morbidity, perioperative experience, length of hospital stays and clinical outcome were analysed. Laparoscopic surgery was successful in all 50 patients and is clearly an option for the treatment of early endometrial cancer. Careful patient selection and surgical competency are instrumental in ensuring successful treatment.

    Laparoscopic surgery has gained the acceptance of the hepatobiliary surgical community and expert teams are now advocating major laparoscopic liver resections (LLRs). In this setting, the liver hanging maneuver (LHM) has been described in numerous series. We conducted a systematic review to investigate the effectiveness of the LHM in LLR. We performed an electronic literature search using PubMed, EMBASE, and COCHRANE databases. The final search was carried out in December, 2015. We found 11 articles describing a collective total of 104 surgical procedures that were eligible for this study. Laparoscopic LHM was used in LLR for both benign and malignant conditions, and also in living donor liver transplantation (LDLT). The LHM was used mainly in right hepatectomy and only two authors reproduced the original LHM. We investigated the intraoperative parameters, preservation of postoperative liver function, and oncological outcomes. The clear benefit of using the LHM in LLR is for better identification of the parenchymal transection plane with less blood loss. The other benefits of LHM could not be corroborated by solid data on its positive value. In view of the data published in the literature, our findings are not strong enough to support the systematic use of LHM in LLR.

    Laparoscopic surgery is increasingly replacing the open procedure because of its many patient-related benefits that are well aligned with policies and programs that seek to optimize health system performance. However, widespread adoption of laparoscopic surgery has been slow, in part, because of the complexity of laparoscopic suturing. The objective of this study was to review the clinical and economic impacts of laparoscopic suturing in key procedures and to assess its role as a barrier to the broader adoption of laparoscopic surgery. A medical literature search of MEDLINE, EMBASE, and BIOSIS from January 2010 through June 2016 identified 47 relevant articles. Laparoscopic suturing and intracorporeal knot tying may result in extended surgical time, complications, and surgeon errors, while improving patient quality of life through improved cosmesis, diet toleration, and better bowel movements. Despite advancement in surgical techniques and the availability of newer surgical tools, the complexity of laparoscopic suturing continues to be a barrier to greater adoption of MIS. The results of the study underscore the need for development of proficiency in laparoscopic suturing, which may help improve patient outcomes and reduce healthcare costs.

    Summary The emphasis on high-school blood drives and acceptance of 16-year-old blood donors led to more research on physiologic and psychological ways to decrease vasovagal reaction rates in young blood donors and to increase donor retention. Research on how to accomplish this has been advantageous for the blood collection industry and blood donors. This review discussed the current situation and what can be done psychologically, physiologically, and via process improvements to decrease vasovagal reaction rates and increase donor retention. The donation process can be significantly improved. Future interventions may include more dietary salt, a shorter muscle tension program to make it more feasible, recommendations for post-donation muscle tension / squatting / laying down for lightheadedness, more donor education by the staff at the collection site, more staff attention to donors with fear or higher risk for a vasovagal reaction (e.g. estimated blood volume near 3.5 l, first-time donor), and a more focused donation process to ensure a pleasant and safer procedure.

  20. Reevaluating the dead donor rule.

    PubMed

    Collins, Mike

    2010-04-01

    The dead donor rule justifies current practice in organ procurement for transplantation and states that organ donors must be dead prior to donation. The majority of organ donors are diagnosed as having suffered brain death and hence are declared dead by neurological criteria. However, a significant amount of unrest in both the philosophical and the medical literature has surfaced since this practice began forty years ago. I argue that, first, declaring death by neurological criteria is both unreliable and unjustified but further, the ethical principles which themselves justify the dead donor rule are better served by abandoning that rule and instead allowing individuals who have suffered severe and irreversible brain damage to become organ donors, even though they are not yet dead and even though the removal of their organs would be the proximal cause of death.

    The utilization rates for minimally invasive colorectal resection techniques (MICR) continue to increase. In some centers MICR methods are the preferred approach, however, open methods continue to be utilized for select patients. In this study, the profile and short-term outcomes of open colorectal resection (CR) and MICR patients are determined and compared. A retrospective review of patients who underwent elective CR over 11 years at two institutions was performed. The MICR group contained both laparoscopic-assisted and hand-assisted cases. The past medical and surgical histories, indications, operations performed, and short-term outcomes were assessed. The Charlson co-morbidity index (CMI) was used to assess risk. During the study period 1080 patients underwent CR (Open, 141; MICR, 939). As judged by the CMI, there were more high-risk patients (score ≥2) in the Open group (34.38%) versus MICR (22.11%) p = 0.0029. Significantly more open patients had prior abdominal surgery and specifically CRs (Open, 15.60% vs. MICR, 2.13%, p < 0.001). Intraoperative transfusion (Open 25.7%; MICR 6.8%, p < 0.001) and diversion (25.53 vs. 11.50%, p < 0.001) were more common in the Open group. Not surprisingly, recovery of bowel function and length of stay were longer for the Open group. The overall complication rate was also higher for the Open patients (p < 0.001). When MICR is the procedure of choice, patients selected for Open CR are higher risk and more complex as judged by the CMI and past operative history. Not surprisingly, this translates into a longer length of stay, higher rates of transfusion, diversion, and complications. This disparity in patients undergoing CRs makes direct comparison of MICR and Open resection outcomes not reasonable.

    Gallstone ileus represents a rare complication (0,3-0,5%) of a serious, but common disease-gallstones, which affect around 10% of the population in the USA and Western Europe. Associated diseases (usually severe), elderly patients, delayed diagnosis and therapy due to late presentation to the hospital, account for the morbidity and mortality rates described in literature. We present the case of a patient with partial colon obstruction due to a large gallstone that was "lost" during an emergency laparoscopic cholecystectomy. The calculus eroded the intestinal wall, partially occluding the lumen, triggering recurrent Kerwsky-like, subocclusive episodes. The intraperitoneal abscess has spontaneously drained through the subhepatic drain and once the tube has been removed, a persistent intermittent fistula became obvious.

    Introduction Cholecystocolic fistula is a rare complication of gallbladder disease. Its clinical presentation is variable and nonspecific, and the diagnosis is made, mostly, incidentally during intraoperative maneuver. Cholecystectomy with closure of the fistula is considered the treatment of choice for the condition, with an increasingly reproducible tendency to the use of laparoscopy. Aim To describe the laparoscopic approach for cholecystocolic fistula and ratify its feasibility even with the unavailability of more specific instruments. Technique After dissection of the communication and section of the gallbladder fundus, the fistula is externalized by an appropriate trocar and sutured manually. Colonic segment is reintroduced into the cavity and cholecystectomy is performed avoiding the conversion procedure to open surgery. Conclusion Laparoscopy for resolution of cholecystocolic fistula isn't only feasible, but also offers a shorter stay at hospital and a milder postoperative period when compared to laparotomy.

    Herein I describe my >12-year experience with laparoscopic common bile duct exploration (LCBDE). From 21 September 1989 through 31 December 2001, 3,580 patients presented with symptomatic biliary tract disease. Laparoscopic cholecystecomy (LC) was attempted in 3,544 of them (99.1%) and completed in 3,527 (99.5%). Laparoscopic cholangiograms (IOC) were performed in 3,417 patients (96.4%); in 344 cases (9.7%), the IOC was abnormal. Forty-nine patients (1.4%) underwent preoperative endoscopic retrograde cholangiopancreatography (ERCP), and 33 patients (0.9%) underwent postoperative ERCP. LCBDE was attempted in 326 cases and completed in 321 (98.5%). It was successful in clearing the duct in 317 of the 344 patients with abnormal cholangiograms (92.2%). The mean operating time for all patients undergoing LC with or without cholangiograms or LCBDE or other additional surgery was 56.9 min. Mean length of stay was 22.1 h. The mean operating time for LC only patients ( n = 2530)--that is, those not undergoing LCBDE or any other additional procedure--was 47.6 min; their mean postoperative length of stay was 17.2 h. Ductal exploration was performed via the cystic duct in 269 patients, (82.5%) and through a choledochotomy in 57 patients (17.5%). T-tubes were used in patients in whom there was concern for possible retained debris or stones, distal spasm, pancreatitis, or general poor tissue quality secondary to malnutrition or infection. In cases where choledochotomy was used, a T-tube was placed in 38 patients (67%), and primary closure without a T-tube was done in 19 (33%). There were no complications in the group of patients who underwent choledochotomy and primary ductal closure without T-tube placement or in the group in whom T-tubes were placed. Common bile duct (CBD) stones still occur in 10% of patients. These stones are identified by IOC. IOC can be performed in >96.4% of cases of LC. LCBDE was successful in clearing these stones in 97.2% of patients in whom it was

    Mandatory predonation reading materials inform donors about risk factors for transmissible disease, possible complications of donation and changes to the donation process. We aimed to assess the attention to predonation reading materials and factors which may affect attention. A national survey in 2008 of 18,108 blood donors asked about self-assessed attention to reading the materials. In face-to-face interviews, 441 donors completed additional questions about reading the materials and a literacy test. Qualitative interviews of 27 donors assessed their approach to reading. In the national survey, most of the first-time donors said they read all or most of the materials (90.9% first-time vs. 57.6% repeat donors, P < 0.001) and 66% vs. 23.1% reported reading them carefully (P < 0.001). In face-to-face interviews comparing those who read materials carefully, skimmed or did not read, most knew that donors are informed of positive transmissible disease test results (97.1%, 95.5, 98.0 P > 0.05), but fewer recalled seeing the definition of sex (77.2%, 56.9, 24.2 P < 0.001). Literacy was poor (30.5% frustration level, 60.3% instructional, 9.2% independent) but similar when those who read materials carefully, skimmed or did not read were compared (P > 0.05). Qualitative interviews showed that donors are reluctant to read any more than necessary and decide based on perceived importance or relevance. Attention to predonation reading materials tends to be better among first-time donors. The effectiveness is limited by low motivation to read, especially for repeat donors, as well as poor literacy. © 2015 International Society of Blood Transfusion.

    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.

    To report our experience of pure laparoscopic and robot-assisted laparoscopic reconstructive surgery in congenital megaureter, seven patients (one bilateral) with symptomatic congenital megaureter underwent pure laparoscopic or robot-assisted laparoscopic surgery. The megaureter was exposed at the level of the blood vessel and was isolated to the bladder narrow area. Extreme ureter trim and submucosal tunnel encapsulation or papillary implantations and anti-reflux ureter bladder anastomosis were performed intraperitoneally by pure laparoscopic or robot-assisted laparoscopic surgery. The clinical data of seven patients after operation were analyzed, including the operation time, intraoperative complications, intraoperative bleeding volumes, postoperative complications, postoperative hospitalization time and pathological results. All of the patients were followed. The operation was successfully performed in seven patients. The mean operation times for pure laparoscopic surgery and robotic-assistant laparoscopic surgery were 175 (range: 150-220) and 187 (range: 170-205) min, respectively, and the mean operative blood loss volumes were 20 (range: 10-30) and 28.75 (range: 15-20) ml, respectively. There were no intraoperative complications. The postoperative drainage time was 5 (range: 4-6) and 5.75 (range: 5-6) d, respectively, and the indwelling catheter time was 6.33 (range: 4-8) d and 7 (range: 7-7) d, respectively. The postoperative hospitalization time was 7.67 (range: 7-8) d and 8 (range: 7-10) d, respectively. There was no obvious pain, no secondary bleeding and no urine leakage after the operation. Postoperative pathology reports revealed chronic urothelial mucosa inflammation. The follow-up results confirmed that all patients were relieved of their symptoms. Both pure laparoscopic and robot-assisted laparoscopic surgery using different anti-reflux ureter bladder anastomoses are safe and effective approaches in the minimally invasive treatment of congenital

    In 2005, the government of Lombardy, an Italian region with an ethnically varied population of approximately 9.8 million inhabitants including 250,000 blood donors, founded the Lombardy Rare Donor Programme, a regional network of 15 blood transfusion departments coordinated by the Immunohaematology Reference Laboratory of the Ca' Granda Ospedale Maggiore Policlinico in Milan. During 2005 to 2012, Lombardy funded LORD-P with 14.1 million euros. During 2005-2012 the Lombardy Rare Donor Programme members developed a registry of blood donors and a bank of red blood cell units with either rare blood group phenotypes or IgA deficiency. To do this, the Immunohaematology Reference Laboratory performed extensive serological and molecular red blood cell typing in 59,738 group O or A, Rh CCDee, ccdee, ccDEE, ccDee, K- or k- donors aged 18-55 with a record of two or more blood donations, including both Caucasians and ethnic minorities. In parallel, the Immunohaematology Reference Laboratory implemented a 24/7 service of consultation, testing and distribution of rare units for anticipated or emergent transfusion needs in patients developing complex red blood cell alloimmunisation and lacking local compatible red blood cell or showing IgA deficiency. Red blood cell typing identified 8,747, 538 and 33 donors rare for a combination of common antigens, negative for high-frequency antigens and with a rare Rh phenotype, respectively. In June 2012, the Lombardy Rare Donor Programme frozen inventory included 1,157 red blood cell units. From March 2010 to June 2012 one IgA-deficient donor was detected among 1,941 screened donors and IgA deficiency was confirmed in four previously identified donors. From 2005 to June 2012, the Immunohaematology Reference Laboratory provided 281 complex red blood cell alloimmunisation consultations and distributed 8,008 Lombardy Rare Donor Programme red blood cell units within and outside the region, which were transfused to 2,365 patients with no

    Large registries of potential unrelated stem cell donors have been established in order to enable stem cell transplantation for patients without HLA-identical related donors. Donor search is complicated by the fact that the stored HLA information of many registered donors is incomplete. We carried out a project that was aimed to improve chances of patients with ongoing donor searches to find an HLA-matched unrelated donor. For that purpose, we carried out additional donor center-initiated HLA-DRB1 typing of donors who were only typed for the HLA loci A and B so far and were potential matches for patients in need of a stem cell transplant. In total, 8,861 donors were contacted for donor center-initiated HLA-DRB1 typing within 1,089 donor searches. 12 of these donors have donated stem cells so far, 8 thereof for their respective target patients. We conclude that chances of patients with ongoing donor searches to find an HLA-matched unrelated donor can indeed be improved by donor-center initiated typing that is carried out in addition to the standard donor search process. Our results also raise questions regarding the appropriate use of incompletely typed donors within unrelated donor searches. PMID:21625451

    There are more than 325 living kidney donors who have developed end-stage renal disease and have been listed on the Organ Procurement and Transplantation Network (OPTN)/United Network for Organ Sharing (UNOS) deceased donor kidney wait list. The OPTN/UNOS database records where these kidney donors are listed and, if they donated after April 1994, where that donation occurred. These 2 locations are often not the same. In this commentary, I examine whether a national living donor registry should be created and whether transplantation centers should be notified when one of their living kidney donors develops end-stage renal disease. I consider and refute 5 potential objections to center notification. I explain that transplantation centers should look back at these cases and input data into a registry to attempt to identify patterns that could improve donor evaluation protocols. Creating a registry and mining the information it contains is, in my view, our moral and professional responsibility to future patients and the transplantation endeavor. As individuals and as a community, we need to acknowledge the many unknown risks of living kidney donation and take responsibility for identifying these risks. We then must share information about these risks, educate prospective donors about them, and attempt to minimize them.

    The Gold standard treatment for symptomatic gallstone disease is laparoscopic cholecystectomy (LC) since 1990. LC can be performed safely as a day case procedure. The objective of this study was to evaluate the results of laparoscopic cholecystectomy in symptomatic gall stones disease in terms of length of hospital stay, complications, morbidity and mortality. This retrospective descriptive study was carried out in Department of General & Laparoscopic Surgery, AK CMH, Muzaffarabad. Notes of all patients who underwent laparoscopic cholecystectomy in the department over a 26 month period were reviewed from department register. Demographics as well as details of cases, conversion to open operation and complications of surgery and anaesthesia were reviewed from clinical notes and departmental register and noted on a designed Performa. Data were analysed using SPSS-18 and results compared with international studies. Out of 500 patients, 443 (88.6%) were females and 57 (11.4%) were males. The mean age of the patients was 42.47 +/- 11.43 years. Mean operative time was 40.09 +/- 11.16 minutes. Seven (1.4%) patients developed port site wound infection. Sixteen (3.2%) cases were converted to open surgery in face of obscured anatomy of Calot's triangle. Two (0.4%) cases has cystic duct stoma leak secondary to missed Common duct stones and were dealt with ERCP and stone extraction. There was no case of bile duct injury, major haemorrhage or bowel injury. There was no mortality associated with laparoscopic cholecystectomy in our series. Laparoscopic cholecystectomy is a safe and effective management of gall stone disease. Better training, careful case selection, meticulous technique and high standard equipment are of paramount importance for ensuring good results in laparoscopic cholecystectomy.

    Background: Surgical treatment of complicated colonic diverticular disease is still debatable. The aim of this prospective study was to evaluate the outcome of laparoscopic sigmoid colectomy in patients with diverticulitis. Patients offered laparoscopic surgery presented with acute complicated diverticulitis (Hinchey type I, II, III), chronically recurrent diverticulitis, bleeding, or sigmoid stenosis caused by chronic diverticulitis. Method: All patients who underwent laparoscopic colectomy within a 12-year period were prospectively entered into a database registry. One-stage laparoscopic resection and primary anastomosis constituted the planned procedure. A 4-trocar approach with suprapubic minilaparotomy was performed. Main data recorded were age, sex, postoperative pain, return of bowel function, operation time, duration of hospital stay, and early and late complications. Results: During the study period, 260 sigmoid colectomies were performed for diverticulitis. The cohort included 104 male and 156 female patients; M to F ratio was 4:6. Postoperative pain was controlled by NSAIDs or weak opioid analgesia. Fifteen patients (5.7%) required conversion from laparoscopic to open colectomy. The most common reasons for conversion were directly related to the inflammatory process, abscess, and peritonitis. Mean operative time was 130±54. Average postoperative hospital stay was 10±3 days. A longer hospital stay was recorded for Hinchey type IIb patients. Complications were recorded in 30 patients (11.5%). The most common complications that required reoperation were hemorrhage in 2 patients (0.76) and anastomotic leak in 5 patients (only 3 of them required reoperation). The mortality among them was 2 patients (0.76%). Conclusions: Laparoscopic surgery for diverticular disease is safe, feasible, and effective. Therefore, laparoscopic colectomy has replaced open resection as standard surgery for recurrent and complicated diverticulitis at our institution. PMID:21605507

    Superior mesenteric artery (SMA) syndrome is a mechanical duodenal obstruction by the SMA. The traditional approach to SMA syndrome was open bypass surgery. Nowadays, a conventional approach has been replaced by laparoscopic surgery. But single incision laparoscopic approach for SMA syndrome is rare. Herein, we report the first case of SMA syndrome patient who was treated by single incision laparoscopic duodenojejunostomy.

    2003-06-07

    FROM AN EPIDEMIOLOGICAL POINT OF VIEW: The epidemiology of renal transplantation had greatly changed over the past 10 years. The increasing number of patients with renal failure and candidates for transplantation increases the demand for grafts, whereas the sampling rate of organs remains stable. The mean age of the donors is rising, hence underlining the question of the use of organs of so-called "borderline" quality. THE WEAK POINTS OF ELDERLY GRAFTS: Aging of the kidneys affects the structure of the parenchyma and renal function, which decreases, notably in hypertensive persons. The elderly graft exhibits a critical mass of nephrons that is insufficient to fulfil the functional requirements of a poorly equipped recipient. The recipient is more sensitive to the added agressions: prolonged ischemia and immunological and medicinal agressions. THE RESULTS OF RENAL GRAFT FROM ELDERLY DONORS: They are quantitatively and qualitatively inferior to those of renal transplants from "ideal" donors. The donor's age is a significant factor influencing negatively influences the survival of the transplanted kidney, but dependent on past vascular history. Good results regarding the maintenance of dialysis are obtained by selecting the donors and by avoiding added risk factors. THE ASSESSMENT OF A GRAFT FROM AN ELDERLY DONOR: This, basically, relies on clinical criteria: donor's history, cause of death and accurate measurement of the renal function. A biopsy of the graft, at the time of sampling, provides useful information. TRANSPLANTATION STRATEGY OF A GRAFT FROM AN ELDERLY DONOR: Donor-recipient matching by age is a common approach. Grafting of both kidneys in the same recipient is a method presently under assessment. The episode of ischemia must be reduced and the immunosuppressive therapy adapted.

    This study tested the efficacy of interventions to recruit new plasma donors among whole blood donors. A sample of 924 donors was randomized to one of three conditions: control; information only by nurse; and information plus self-positive image message by nurse (SPI). Participants in the control condition only received a leaflet describing the plasma donation procedure. In the two experimental conditions the leaflet was explained face-to-face by a nurse. The dependent variables were the proportion of new plasma donors and the number of donations at six months. Overall, 141 (15.3%) new plasma donors were recruited at six months. There were higher proportions of new plasma donors in the two experimental conditions compared to the control condition (P < .001); the two experimental conditions did not differ. Also, compared to the control condition, those in the experimental conditions (all Ps < .001) gave plasma more often (information only by nurse:  d = .26; SPI: d = .32); the SPI intervention significantly outperformed (P < .05) the information only by nurse condition. The results suggest that references to feelings of SPI such as feeling good and being proud and that giving plasma is a rewarding personal experience favor a higher frequency of plasma donation.

    1995-04-01

    Laparoscopic and endoscopic surgery rely uniquely on high quality display of acquired images, but a multitude of problems plague the researcher who attempts to reproduce such images for educational purposes. Some of these are intrinsic limitations of current laparoscopic/endoscopic visualization systems, while others are artifacts solely of the process used to acquire and reproduce such images. Whatever the genesis of these problems, a glance at current literature will reveal the extent to which endoscopy suffers from an inability to reproduce what the surgeon sees during a procedure. The major intrinsic limitation to the acquisition of high-quality still images from laparoscopic procedures lies in the inability to couple directly a camera to the laparoscope. While many systems have this capability, this is useful mostly for otolaryngologists, who do not maintain a sterile field around their scopes. For procedures in which a sterile field must be maintained, one trial method has been to use a beam splitter to send light both to the still camera and the digital video camera. This is no solution, however, since this results in low quality still images as well as a degradation of the image that the surgeon must use to operate, something no surgeon tolerates lightly. Researchers thus must currently rely on other methods for producing images from a laparoscopic procedure. Most manufacturers provide an optional slide or print maker that provides a hardcopy output from the processed composite video signal. The results achieved from such devices are marginal, to say the least. This leaves only one avenue for possible image production, the videotape record of an endoscopic or laparoscopic operation. Video frame grabbing is at least a problem to which industry has applied considerable time and effort to solving. Our own experience with computerized enhancement of videotape frames has been very promising. Computer enhancement allows the researcher to correct several of the

    Controversy exists over the proper methods of sterilizing laparoscopic telescopes. An edict requiring gas sterilization rather than solution soaking of these instruments is in force in all federal hospitals. This rule has necessitated capital investments for new instruments and has led to a severe reduction in the number of cases of laparoscopy that may be scheduled in one day. Fear of contamination is based on theoretical considerations and rusn counter to the actual, observed safety record seen with laparoscopes soaked in activated glutaraldehyde between cases. In an effort to dispassionately approach this problem, cultures of the umbilical area, the laparoscope and the pelvic serosal surfaces were taken to document the type of organisms commonly encountered under clinical conditions. Cultures for aerobic and anaerobic bacteria as well as for fungi were taken after soaking the telescope in activated glutaraldehyde. The results demonstrated growth of common skin organisms even after skin preparation with povidone-iodine and ethyl alcohol. Similar organisms were recovered in some cases from the laparoscope and the pelvic surfaces. The actual degree of contamination suggested by a colony count falls well within the range of the healthy peritoneum to cope with these organisms. Recommendations for laparoscopic sterilization or disinfection are based on the results obtained.

    To describe our 13-year experience in laparoscopic adrenalectomy for phaeochromocytoma. We performed a retrospective analysis of case notes of 29 patients who underwent laparoscopic adrenalectomy for phaeochromocytoma between 2000 and 2013. Twenty-nine patients (16 female), aged 16 to 67 years, underwent laparoscopic adrenalectomy for phaeochromocytoma. All patients were treated preoperatively with alpha-blocking agents. 80% were prescribed additional preoperative antihypertensive agents. 90% received antihypertensive agents intraoperatively. All patients received intraoperative magnesium sulphate for haemodynamic stabilisation. The mean operative time was 160 minutes. Nearly all of the patients experienced haemodynamic stability during surgery. Two patients required conversion to open adrenalectomy, due to severe intraoperative hypertension during tumour handling, and due to extensive intra-abdominal adhesions. Postoperative complications were minimal, and included blood loss, superior epigastric artery damage, and cellulitis at the laparoscopic port site. There was no perioperative mortality. The median length of stay postoperatively was 4 days. 24% were prescribed antihypertensive medication on discharge. In our experience, favourable perioperative outcomes were achieved, demonstrating that laparoscopic adrenalectomy for phaeochromocytoma is a safe and effective procedure in the setting of experienced and skilled surgical, anaesthetic and medical teams delivering the perioperative care.

    Laparoscopic surgery provides a very complex example of medical image interpretation. The task entails: visually examining a display that portrays the laparoscopic procedure from a varying viewpoint; eye-hand coordination; complex 3D interpretation of the 2D display imagery; efficient and safe usage of appropriate surgical tools, as well as other factors. Training in laparoscopic surgery typically entails practice using surgical simulators. Another approach is to use cadavers. Viewing previously recorded laparoscopic operations is also a viable additional approach and to examine this a study was undertaken to determine what differences exist between where surgeons look during actual operations and where they look when simply viewing the same pre-recorded operations. It was hypothesised that there would be differences related to the different experimental conditions; however the relative nature of such differences was unknown. The visual search behaviour of two experienced surgeons was recorded as they performed three types of laparoscopic operations on a cadaver. The operations were also digitally recorded. Subsequently they viewed the recording of their operations, again whilst their eye movements were monitored. Differences were found in various eye movement parameters when the two surgeons performed the operations and where they looked when they simply watched the recordings of the operations. It is argued that this reflects the different perceptual motor skills pertinent to the different situations. The relevance of this for surgical training is explored.

    Camera calibration is a key requirement for augmented reality in surgery. Calibration of laparoscopes provides two challenges that are not sufficiently addressed in the literature. In the case of stereo laparoscopes the small distance (less than 5mm) between the channels means that the calibration pattern is an order of magnitude more distant than the stereo separation. For laparoscopes in general, if an external tracking system is used, hand-eye calibration is difficult due to the long length of the laparoscope. Laparoscope intrinsic, stereo and hand-eye calibration all rely on accurate feature point selection and accurate estimation of the camera pose with respect to a calibration pattern. We compare 3 calibration patterns, chessboard, rings, and AprilTags. We measure the error in estimating the camera intrinsic parameters and the camera poses. Accuracy of camera pose estimation will determine the accuracy with which subsequent stereo or hand-eye calibration can be done. We compare the results of repeated real calibrations and simulations using idealised noise, to determine the expected accuracy of different methods and the sources of error. The results do indicate that feature detection based on rings is more accurate than a chessboard, however this doesn't necessarily lead to a better calibration. Using a grid with identifiable tags enables detection of features nearer the image boundary, which may improve calibration.

    Purpose Retroperitoneal neural tumor (RNT) is rarely excised laparoscopically, and the laparoscopic management of RNT remains controversial. We herein report 4 cases of laparoscopic excision of RNT that resulted in diverse clinical outcomes. Patients and Methods Between August 2005 and January 2011, we performed laparoscopic excision of RNT in 4 patients. The mean tumor size was 4.5 cm. The mean operative time was 297 minutes and the mean amount of blood loss was 55 ml. The surgeries were uneventful, with no operative complications or evidence of intra-abdominal bleeding. However, 2 patients required reoperation for delayed hemorrhage and urinoma formation, respectively. Results The postoperative pathological diagnoses were schwannoma in 3 patients and ganglioneuroblastoma in 1 patient. All patients were well with no signs of peripheral neuropathy or radiculopathy, and CT and/or 18F-FDG PET/CT performed during follow-up indicated no evidence of disease. Conclusions Obtaining extensive preoperative knowledge of the source neural and vascular anatomy of the tumor is important for the surgical planning of laparoscopic resection of RNT. When a great deal of care is taken to divide the tumor and the source nerves and vital vessels, safe execution of RNT can be achieved for minimal postoperative mortality and morbidity. PMID:24917756

    To examine the feasibility of early laparoscopic ureteroneocystostomy for ureteral obstruction due to hysterectomy injury. We retrospectively reviewed a 10-y experience from 2 institutions in patients who underwent early (<30 d) or late (>30 d) laparoscopic ureteroneocystostomy for ureteral injury after hysterectomy. Evaluation of the surgery included the cause of the stricture and intraoperative and postoperative outcomes. A total of 9 patients with distal ureteral injury after hysterectomy were identified. All injuries were identified and treated as early as 21 d after hysterectomy. Seven of 9 patients underwent open hysterectomy, and the remaining patients had vaginal and laparoscopic radical hysterectomy. All ureteroneocystostomy cases were managed laparoscopically without conversion to open surgery and without any intraoperative complications. The Lich-Gregoir reimplantation technique was applied in all patients, and 2 patients required a psoas hitch. The mean operative time was 206.6 min (range, 120-280 min), the mean estimated blood loss was 122.2 cc (range, 25-350 cc), and the mean admission time was 3.3 d (range, 1-7 d). Cystography showed no urine leak when the ureteral stent was removed at 4 to 6 wk after the procedure. Ureteroneocystostomy patency was followed up with cystography at 6 mo and at least 10 y after ureteroneocystostomy. Early laparoscopic ureteral reimplantation may offer an alternative surgical approach to open surgery for the management of distal ureteral injuries, with favorable cosmetic results and recovery time from ureteral obstruction due to hysterectomy injury.

    Music education affects the mathematical and visuo-spatial skills of school-age children. Visuo-spatial abilities have a significant effect on laparoscopic suturing performance. We hypothesize that prior music experience influences the performance of laparoscopic suturing tasks. Thirty novices observed a laparoscopic suturing task video. Each performed 3 timed suturing task trials. Demographics were recorded. A repeated measures linear mixed model was used to examine the effects of prior music experience on suturing task time. Twelve women and 18 men completed the tasks. When adjusted for video game experience, participants who currently played an instrument performed significantly faster than those who did not (P<0.001). The model showed a significant sex by instrument interaction. Men who had never played an instrument or were currently playing an instrument performed better than women in the same group (P=0.002 and P<0.001). There was no sex difference in the performance of participants who had played an instrument in the past (P=0.29). This study attempted to investigate the effect of music experience on the laparoscopic suturing abilities of surgical novices. The visuo-spatial abilities used in laparoscopic suturing may be enhanced in those involved in playing an instrument.

    Background and Objectives: To compare laparoscopic appendectomy with traditional open appendectomy. Methods: Seventy-one patients requiring operative intervention for suspected acute appendicitis were prospectively compared. Thirty-seven patients underwent laparoscopic appendectomy, and 34 had open appendectomy through a right lower quadrant incision. Length of surgery, postoperative morbidity and length of postoperative stay (LOS) were recorded. Both groups were similar with regard to age, gender, height, weight, fever, leukocytosis, and incidence of normal vs. gangrenous or perforated appendix. Results: Mean LOS was significantly shorter for patients with acute suppurative appendicitis who underwent laparoscopic appendectomy (2.5 days vs. 4.0 days, p<0.01). Mean LOS was no different when patients classified as having gangrenous or perforated appendicitis were included in the analysis (3.7 days vs. 4.1 days, P=0.11). The laparoscopy group had significantly longer surgery times (72 min vs. 58 min, p<0.001). There was no significant difference in the incidence of postoperative morbidity. Conclusions: Laparoscopic appendectomy reduces LOS as compared with the traditional open technique in patients with acute suppurative appendicitis. The longer operative time for the laparoscopic approach in our study is likely related to the learning curve associated with the procedure and did not increase morbidity. PMID:9876729

    Laparoscopic cholecystectomy has been considered as a safe and effective procedure without randomised prospective trial. Two physician insurers associations (in France and in USA) have shown an important increase of the lawsuits after laparoscopic cholecystectomy, especially concerning common bile duct injuries. An exhaustive study of the literature demonstrates that in the rare prospective studies collecting all of the laparoscopic cholecystectomies realised in one country or one state, the percentage of biliary tract injuries is form twice to five times as big as with open surgery, and bigger in case of acute cholecystitis. It seems that diffusion of the monopolar current can explain a good number of them. These injuries are difficult for repairing because of their high localisation and the associated tissular burn. Their long term morbidity is important and their cost is huge. Three recent prospective studies comparing laparoscopic versus minilaparotomy approach demonstrate that the advantages of laparoscopic approach according to the cost and the recovery's speed are, except for the obese patients, less evident than one could believe.

    Laparoscopic surgery is associated with reduced surgical trauma, and therefore with a less acute phase response, as compared with open surgery. Impairment of the immune system may enhance surgical infections, port-site metastases, and sepsis. The objectives of this review was to assess immunologic consequences of benign laparoscopic surgery and to highlight controversial aspects. A literature search on stress response to nonmalignant laparoscopic and open surgery was conducted using the MEDLINE and Cochrane databases. Cross-references from the reference list of major articles on the subject were used, as well as manuscripts published between 1993 and 2002. Local (i.e., peritoneal) immune function is affected by carbon dioxide pneumoperitoneum. The production of tumor necrosis factor and the phagocytotic capacity of peritoneal macrophages are less lowered. The systemic stress response, as determined by delayed-type hypersensitivity response and leukocyte antigen expression on lymphocytes, shows a preservation of immune function after laparoscopic surgery, as compared with conventional surgery. Intraperitoneal carbon dioxide insufflation attenuates peritoneal immunity, but laparoscopic surgery is associated with a lower systemic stress response than open surgery.

    Introduction: We evaluated the feasibility of laparoscopic cytoreduction for primary advanced ovarian cancer. Methods: All patients with presumed stage 3/4 primary ovarian cancer underwent attempted laparoscopic cytoreduction. All patients had CT evidence of omental metastasis and ascites. A 5-port (5-mm) transperitoneal approach was used. A bilateral salpingo-oophorectomy, supracervical hysterectomy, and omentectomy were performed with PlasmaKinetic (PK) cutting forceps. A laparoscopic 5-mm Argon-Beam Coagulator was used to coagulate tumor in the pelvis, abdominal peritoneum, intestinal mesentery, and diaphragm. Results: Nine of 11 cases (82%) were successfully de-bulked laparoscopically without conversion to laparotomy. Median operative time was 2.5 hours, and median blood loss was 275 mL. All tumors were debulked to <2 cm and 45% had no residual disease. Stages were 1–3B, 7–3C, and 1–4. Median length of stay was one day. Median VAS pain score was 4 (discomforting). Two of 11 patients (18%) had postoperative complications. Conclusion: Laparoscopic cytoreduction was successful and resulted in minimal morbidity. Because of our small sample size, additional studies are needed. PMID:20529532

    Most general surgeons are familiar with monopolar electrocautery, but few are equally comfortable with laser dissection and coagulation. At courses across the country, surgeons are being introduced to laparoscopy and laser use in one and two day courses, and are certified from that day forward as laser laparoscopists. Some surgeons are told that laser and electrosurgery may be equally acceptable techniques for performance of laparoscopic surgery, but that a surgeon may double his patient volume by advertising 'laser laparoscopic cholecystectomy.' The sale of certain lasers has skyrocketed on the basis of such hype. The only surprise is that laparoscopic cholecystectomy complications occurring in this country seem to be more closely related to the laparoscopic access and visualization than to the choice of laser of electrocautery as the preferred instrument for thermal dissection. The purpose of this article is to: 1) Discuss the physics and tissue effects of electrosurgery and laser; 2) compare the design and safety of electrosurgical and laser delivery systems; and 3) present available data comparing laser and electrocautery application in laparoscopic cholecystectomy.

    Since introduction of laparoscopic appendectomy we have the possibility to examine the whole abdominal cavity and not only the ileocaecal region and right adnex. The aim of the study is to find out if there is an advantage in laparoscopic diagnostics compared to conventional laparotomy for suspected acute appendicities. We compared prospectively all patients who underwent laparoscopy for acute right lower abdominal pain between August 1991 and March 1993 with a comparable group retrospectively analyzed who underwent conventional appendectomy in 1989. In both groups 20% of patients had a normal appendix. In 1% of the laparoscopically operated patients we couldn't find any pathological findings, in 12% of the conventionally operated group we couldn't find an accurate diagnosis. The average operation time of laparoscopically operated patients without acute appendicities was 20 minutes shorter compared to conventionally operated patients. We found identically results for the duration of hospital stay. The median hospital stay for conventionally operated patients was 6.6 days, for laparoscopically operated patients 4.7 days. The complications were in both groups 1-2%. We conclude that in laparoscopy the diagnostics are more reliable, and with a diagnostic accuracy of almost 100% the unnecessary appendectomy with a higher morbidity would not be necessary in 12% of patients.

    Aim: In this review, we assessed the feasibility of total laparoscopic hysterectomy (TLH) in cases of very large uteri weighing more than 500 grams. We have analyzed whether it is possible for an experienced laparoscopic surgeon to perform efficient total laparoscopic hysterectomy for large myomatous uteri regardless of the size, number and location of the myomas. Design: Retrospective review (Canadian Task Force Classification II-1) Setting: Dedicated high volume Gynecological laparoscopy centre. Patients: 173 women with symptomatic myomas who underwent total laparoscopic hysterectomy at our center. There were no exclusion criteria based on the size number or location of myomas. Intervention: TLH and modifications of performing the surgery by ligating the uterine arteries prior, myomectomy followed by hysterectomy, direct morcellation after uterine artery ligation. Results: 72% of patients had previous normal vaginal delivery and 28% had previous cesarean section. Average clinical size of the uterus was 18 weeks (10, 32). The average weight of the specimen was 700 grams (500, 2240). The average duration of surgery was 107 min (40, 300) and the average blood loss was 228 ml (10, 3200). Conclusion: Total laparoscopic hysterectomy is a technically feasible procedure. It can be performed by experienced surgeons for large uteri regardless of the size, number or location of the myomas.

    An important drawback of the traditional technique for harvesting latissimus dorsi (LD) myocutaneous flap is a long, posterior donor-site incision. Current techniques involve endoscopic or robotic harvesting via a combined approach of open and closed surgery, which necessitates an open axillary incision and the use of special retractors. In this paper, we introduce a fully enclosed laparoscopic technique for harvesting LD flap (LDF) using only 3 small trocar ports. This technique eliminates the need for axillary and donor-site incisions and specialized retractors and considerably reduces the incision size. We performed laparoscopic harvesting of LDF with prosthesis implantation for immediate breast reconstruction (IBR) after nipple-sparing mastectomy in 2 patients with malignant breast neoplasm who wished to avoid a long scar on the back. IBR using this technique was uneventful in both cases, without any donor-site complications or flap failure. Both patients were satisfied with the esthetic results of the procedure, especially the absence of a visible scar on the back. Enclosed laparoscopic harvesting of LDF is simpler and less invasive than the traditional methods. These preliminary results warrant further evaluation in a larger population to validate the benefits of this technique.

  14. Donor states in inverse opals

    We calculate the binding energy of an electron bound to a donor in a semiconductor inverse opal. Inverse opals have two kinds of cavities, which we call octahedral and tetrahedral, according to their group symmetry. We put the donor in the center of each of these two cavities and obtain the binding energy. The binding energies become very large when the inverse opal is made from templates with small spheres. For spheres less than 50 nm in diameter, the donor binding can increase to several times its unconfined value. Then electrons become tightly bound to the donor and are unlikely to be thermally activated to the semiconductor conduction band. This conclusion suggests that inverse opals will be poor conductors.

    There is increased scrutiny on the quality in health care with particular emphasis on institutional heart transplant survival outcomes. An important aspect of successful transplantation is appropriate donor selection. We review the current guidelines as well as areas of controversy in the selection of appropriate hearts as donor organs to ensure optimal outcomes. This decision is paramount to the success of a transplant program as well as recipient survival and graft function post-transplant. PMID:25132976

    2005-06-01

    Laparoscopic adrenalectomy is one of the most significant advances in the past 20 years for treating adrenal disorders. When compared with open adrenalectomy, laparoscopic adrenalectomy is equally safe, effective, and curative; it is more successful in shortening hospitalization and convalescence and has less long-term morbidity. The laparoscopic approach is the procedure of choice for the surgical management of cortisol-producing adenomas and for patients who have corticotropin (ACTH)-dependent Cushing's syndrome for whom surgery failed to remove the source of ACTH. The keys to successful laparoscopic adrenalectomy are appropriate patient selection, knowledge of anatomy, delicate tissue handling, meticulous hemostasis, and experience with the technique of laparoscopic adrenalectomy.

    Single incision laparoscopic surgery resection of colon is feasible, but so far evidence of benefit compared to standard laparoscopic technique is lacking. In addition to robot-controlled camera, there is only one robot system on the market capable of performing laparoscopic surgery. The da Vinci robot may contribute to making complex laparoscopic procedures easier to perform, but the system is costly in purchase and maintenance. Natural orifice transluminal endoscopic surgery aiming to reduce abdominal wall trauma is developing and bringing new technology. Combinations of laparoscopic and endoscopic techniques will expand future indications.

    The double-stapling technique (DST) is frequently used in laparoscopic sigmoidectomy. Unfortunately, anastomotic leakage after laparoscopic intracorporeal colorectal anastomosis with DST is seen with some frequency. We performed DST on 40 patients (June 2007 to August 2008) and hemi-DST on 50 patients (September 2008 to December 2011) undergoing laparoscopic sigmoidectomy. There were no occurrences of anastomotic leakage in the hemi-DST group, and 2 instances of anastomotic leakage in the DST group were observed. In these patients, the leakage appeared at the lateral intersecting anastomotic margins. Using the hemi-DST for laparoscopic intracorporeal colorectal anastomosis will make laparoscopic sigmoidectomy a safer procedure.

    Minimally invasive surgery has been replacing the open standard technique in several procedures. Similar or even better postoperative outcomes have been described in laparoscopic or robot-assisted procedures when compared to open surgery. Moreover, minimally invasive surgery has been providing less postoperative pain, shorter hospitalization, and thus a faster return to daily activities. However, the learning curve required to obtain laparoscopic expertise has been a barrier in laparoscopic spreading. Laparoscopic surgery training laboratory has been developed to aid surgeons to overcome the challenging learning curve. It may include tutorials, inanimate model skills training (box models and virtual reality simulators), animal laboratory, and operating room observation. Several different laparoscopic courses are available with specific characteristics and goals. Herein, we aim to describe the activities performed in a dry and animal-model training laboratory and to evaluate the impact of different kinds of laparoscopic surgery training courses on surgeon’s performance. Several tasks are performed in dry and animal laboratory to reproduce a real surgery. A short period of training can improve laparoscopic surgical skills, although most of times it is not enough to confer laparoscopic expertise for participants. Nevertheless, this short period of training is able to increase the laparoscopic practice of surgeons in their communities. Full laparoscopic training in medical residence or fellowship programs is the best way of stimulating laparoscopic dissemination. PMID:27933135

    Mini-laparoscopy, or needlescopy, is an emerging minimally invasive technique that aims to improve on standard laparoscopy in the areas of tissue trauma, pain, and cosmesis. The objective of this study was to determine if there was a difference in functionality between 2 novel mini-laparoscopic instruments when compared to standard laparoscopic tools. Differences were assessed in a simulated surgical environment. Twenty participants (5 novices, 10 intermediate, 5 expert) were recruited for this institutional review board-approved study in a surgical simulation training center. Group A tools were assembled intracorporeally, and Group B tools were assembled extracorporeally. Using standard laparoscopic graspers, mini-laparoscopic graspers, or a combination of both, each participant performed 3 basic laparoscopic training tasks: a Peg Transfer, Rubber Band Stretch, and Tootsie Roll Unwrapping. Following each round of tasks, participants completed a survey evaluating the mini-laparoscopic graspers with respect to standard laparoscopic graspers. Data were analyzed using Kruskal-Wallis test with Dunn's test for post hoc comparisons. When comparing task times, both mini tools performed at the level of standard laparoscopic graspers in all participant groups. Group A tools were quicker to assemble and disassemble versus Group B tools. According to posttask surveys, all participant groups indicated that both sets of mini-laparoscopic graspers were comparable to the standard graspers. In a nonclinical setting, mini-laparoscopic instruments perform at the level of standard laparoscopic tools. Based on these results, clinical trials would be a reasonable next step in assessing feasibility and safety.

    Today largely diffused is the concept that laparoscopic cholecystectomy (LC) represents the treatment of choice for symptomatic gallstones. Nonetheless some questions have been raised on the real safety of this new method in terms of procedure-related complications. On the basis of our experience with traditional open cholecystectomy, we have recently performed a prograde LC in those cases with difficulties in identifying the anatomical structures of the so called Calot's triangle. This alternative route can be easily performed laparoscopically and has been useful in reducing the time of the intervention in the most difficult setting and to increase the safety of the procedure. The technical details and the results are compared with those of the laparoscopic retrograde route.

    The standard approach to laparoscopic sleeve gastrectomy (LSG) involves sleeve-forming through a vertical gastrectomy, producing a narrow, tubular stomach. Considerable laparoscopic skills are required to find a suitable size at which the pressure of the sleeve is not excessive and the restriction is sufficient for obtaining good weight-loss effect without increasing the risk of complications. There is no doubt that considerable technical details are required to create a “perfect sleeve.” We report our sleeve-forming technique for LSG involving both vertical gastrectomy and plication, which we have termed “laparoscopic plicated sleeve gastrectomy.” This technique was shown to be safe and efficacious for the treatment of severe obesity and can reduce technical difficulties in the creation of a “perfect sleeve.”

    Bowel perforation is a rare complication of laparoscopic cholecystectomy, which if left undiagnosed can have fatal consequences. In addition, isolated small bowel perforation is extremely rare and should be considered in patients presenting with sudden onset abdominal pain in the postoperative period. A 57-year-old male with symptomatic gallstones underwent urgent laparoscopic cholecystectomy and was discharged home on postoperative day (POD) 1 without complications. He presented to the emergency department on POD 11 complaining of sudden onset abdominal pain. A CT scan did not confirm a diagnosis and he was admitted for observation. On post admission day 2, he became significantly peritonitic and laparotomy revealed jejunal perforation. Bowel resection with hand-sewn anastomosis was completed and he was discharged on POD 10. Follow-up at 6 weeks revealed no further issues. We review the literature on small bowel perforation post laparoscopic cholecystectomy. PMID:26908534

    In typical stereo display systems, the reproduced 3D scene is distorted when the observer moves. Motion parallax is an important depth cue that has the ability to correct this distortion. More importantly, motion parallax enables the observer to look around objects to provide a better view. A robotically assisted laparoscope prototype was designed to provide motion parallax. A study to adjust the camera-head mapping ratio (gain of motion parallax) was performed. A series of phantom tests was conducted to test the effectiveness of motion parallax. The experimental results showed that the motion parallax was effective, and the gain of motion parallax was subjective. For a regular laparoscope view distance, larger image zooming rates required smaller gain; for the same equivalent image size, further observer distance decreased the optimal gain. Motion parallax could be used for improved visualization in laparoscopic surgery. Copyright © 2015 John Wiley & Sons, Ltd. Copyright © 2015 John Wiley & Sons, Ltd.

    Minimally invasive procedures have revolutionised surgery by reducing pain and the length of hospital stay for patients. These are not simple procedures and training in laparoscopic surgery is an arduous process. Meticulous preparation prior to surgery is paramount to prevent complications. We report a rare complication involving a 35-year-old patient who underwent a laparoscopic appendicectomy for a perforated appendix. Two days after surgery the patient experienced redness and swelling in the lower abdominal region and oliguria. A delayed computer tomography (CT) scan revealed contrast leakage around the bladder spreading within the peritoneal cavity consistent with an intraperitoneal bladder perforation. She underwent urinary catheterisation for 6 days. A follow-up CT cystogram showed no evidence of leakage into the peritoneal cavity. This case highlights the need for thorough preparation prior to laparoscopic surgery and careful manipulation of instruments during routine procedures to minimise the risk of serious patient complications such as the aforementioned.

    : This study aimed to evaluate single-stage surgical (laparoscopic or open) approach to the management of common bile duct (CBD) stones, as treatment of choice. Prospectively collected data to assess outcomes of CBD clearance, morbidity, mortality, and hospital stay, and compared with published data. Successful clearance of CBD stones was achieved in 96% cases, laparoscopic exploration successful in 83%. Retained stones were found in 4% cases and another 5% developed postoperative complications. Common length of stay in hospital was 2 days, although mean stay was 4 days. Seventy-three percent of cases were elective, 27% were emergencies. Conversion rate to open surgery was 14%, which was mainly in emergency cases. Postoperative mortality was 1.2%, not directly related to the procedure. Good outcomes can be achieved, comparing favorably with those of other modalities, when laparoscopic bile duct exploration is chosen as treatment for CBD stones; the best results can be anticipated in elective patients.

    Twelve children underwent elective laparoscopic cholecystectomy for symptomatic cholelithiasis during a 10-month period in one institution. The operative technique that has been described for adults was modified because of the smaller dimensions of pediatric patients. These modifications are discussed in this report, as are new alternatives for evaluating the common duct. No operative complications or conversions to open cholecystectomy occurred, and no complications after surgery were seen during an average follow-up period of 4.5 months. The benefits of laparoscopic cholecystectomy include decreased pain and ileus after surgery, shortened hospitalization, and improved cosmesis. Laparoscopic cholecystectomy is safe and efficacious in children, and it compares favorably with traditional cholecystectomy in the pediatric age group. Images FIG. 3. PMID:1532120

    Background and Objectives: Schwannomas are tumors originating from Schwann cells of the peripheral nerve sheath (neurilemma) of the neuroectoderm. Rarely, schwannomas can arise from the retroperitoneum and adrenal medulla. We describe a case of a 71-y-old woman who presented with an incidentally discovered adrenal tumor. Methods: Ultrasound and computed tomography scans revealed a lesion with solid and cystic areas originating from the left adrenal gland. The patient underwent complete laparoscopic resection of the tumor and the left adrenal gland. Results: Histopathological examination and immunohistochemical staining of the excised specimen revealed a benign schwannoma measuring 5.5×5×3.7 cm. To our knowledge, few other cases of laparoscopic resection of adrenal schwannomas have been reported. Conclusion: Because preoperative diagnosis of adrenal tumors is inconclusive, complete laparoscopic excision allows for definitive diagnosis with histological evaluation and represents the treatment of choice.

    This work reports a miniaturized laparoscopic zoom camera that can significantly improve vision for minimally invasive surgery (MIS), also known as laparoscopic surgery. The laparoscopic zoom camera contains bioinspired fluidic lenses that can change curvature and focal length in a manner similar to the crystalline lenses in human eyes. The traditional laparoscope is long, rigid, and made of fixed glass lenses with a fixed field of view. The constricted vision of a laparoscope is often an inconvenience and plays a role in many surgical injuries. To further advance MIS technology, we developed a new type of laparoscopic camera that has a total length of less than 17 mm, greater than 4× optical zoom, and 100 times higher sensitivity than today's laparoscope allowing it to work under illumination as low as 300 lux. All these unique features are enabled by the technology of bioinspired fluidic lenses having a dynamic range over 100 diopters and being convertible between a convex and concave shape.

    2012-07-01

    Laparoscopic surgery is one of the most challenging surgical operations, because inside information about the target organ cannot be fully understood from the laparoscopic image. Therefore, a fusion technique of laparoscopic and ultrasonic images is proposed for guidance during laparoscopic surgery. The proposed technique can display the internal organ structure by overlaying a three-dimensional (3D) ultrasonic image over a 3D laparoscopic image, which is acquired using a stereo laparoscope. The registration of the 3D images is performed by registering the surface of the target organ, which is found in the two 3D images without requiring the use of an external position detecting device. The proposed technique was evaluated experimentally using a tissue-mimicking phantom. Results obtained led to registration accuracy better than 2 cm. The total computation time was 3.1 min on a personal computer (Xeon processor, 3 GHz CPU). The structural information permits the visualization of target organs during laparoscopic surgery.

    The aim of this study was to assess the feasibility and efficacy of laparoscopic myomectomy (LM) for large myomas. A subpopulation of 51 patients with myomas 8 cm or larger in diameter was selected from 155 patients who underwent LM at Kangbuk Samsung Hospital from July 2003 to November 2006. The mean age of the patients was 34.9±5.6 yr, mean parity was 0.6±0.9, and 8 patients had a previous operative history. The most common operative indication was a palpable abdominal mass (24 patients, 47%). The mean operating time was 85.6±38.9 min, and the mean diameter of the largest myoma was 9.3±1.8 cm. The mean change in hemoglobin concentration was 2.1±1.2 g/dL. Histopathological diagnosis included 49 patients of leiomyoma (96.1%) and 2 patients of leiomyoma with adenomyosis (3.9%). Postoperatively, a transfusion was done in 7 patients, and a case of subcutaneous emphysema was noted. None of the operations was switched to laparotomy. With the newly-developed screw and the port placement system that was modified from the Choi's 4-trocar method to obtain better surgical vision, LM of large myomas proved to be one of the efficient and feasible methods.

    The history of bariatric surgery is investigational. Dedicated surgeons have continuously sought for an ideal procedure to relieve morbidly obese patients from their burden of comorbid conditions, reduced life expectancy and low quality of life. The ideal procedure must have low complication risk, both in short- and long term, as well as minimal impact on daily life. The revolution of laparoscopic techniques in bariatric surgery is described in this summary. Advances in minimal invasive techniques have contributed to reduced operative time, length of stay, and complications. The development in bariatric surgery has been exceptional, resulting in a dramatic increase of the number of procedures performed world wide during the last decades. Although, a complex bariatric procedure can be performed with operative mortality no greater than cholecystectomy, specific procedure-related complications and other drawbacks must be taken into account. The evolution of laparoscopy will be the legacy of the 21st century and at present, day-care surgery and further reduction of the operative trauma is in focus. The impressive effects on comorbid conditions have prompted the adoption of minimal invasive bariatric procedures into the field of metabolic surgery. PMID:25386062

    Laparoscopy in cattle is a promising tool for clinical diagnosis and treatment. The lower cost of the materials available in addition to the possibility of an intervention on an animal that is sedated does not entail more costs than an exploratory laparotomy. The application of this tool during abdominal explorations and biopsies allows the avoidance of invasive and often useless surgical interventions and even with the diagnosis and prognosis of certain conditions. Surgical techniques currently are limited to abomasopexies; however, never-ceasing progress and improvements in human surgery are expected to affect the future of bovine surgery. With the advancements in the multimedia technology used by universities, the use of laparoscopy as a pedagogic tool definitely has a promising future. Endoscopic exploration of the thorax is possible using the same material as for laparoscopy. In addition, diagnostic and biopsy applications are useful. The use of the laparoscope in different body cavities and for different applications would make the purchase of the required materials more cost-effective.

    In this Update of our July 1995 Evaluation (Health Devices 24[7]), we tested three high-flow laparoscopic insufflators not covered in the original study. In this issue, we are again using the Product Profile Evaluation format that we introduced in our August 1996 (25[8]) Update Evaluation of automated external defibrillators; see the inset on page 14 for a detailed explanation of this new format. In brief, we evaluated the three new units using the same criteria and test methods as in the July 1995 study and rated and ranked the units according to the same overall scheme. Because our criteria and test methods have not changed since the original study, we have not repeated them in this issue; readers should refer to the July 1995 issue for that information. Instead, in a series of Product Profiles, we present the characteristics, test results, and ratings for each newly evaluated unit individually. Following the profiles, a comprehensive Conclusions section details how the newly evaluated units compare with those evaluated in our original study. One of the units evaluated in this issue is rated Acceptable. The other two are rated Conditionally Acceptable because of their inability to provide adequate pressure relief; a secondary gas source should not be applied in the pneumoperitoneum while these units are in use. Of the 16 units we have evaluated to date, nine are rated Acceptable and seven are rated Conditionally Acceptable.

    2015-01-01

    AIM: To review current applications of the laparoscopic surgery while highlighting the standard procedures across different fields. METHODS: A comprehensive search was undertaken using the PubMed Advanced Search Builder. A total of 321 articles were found in this search. The following criteria had to be met for the publication to be selected: Review article, randomized controlled trials, or meta-analyses discussing the subject of laparoscopic surgery. In addition, publications were hand-searched in the Cochrane database and the high-impact journals. A total of 82 of the findings were included according to matching the inclusion criteria. Overall, 403 full-text articles were reviewed. Of these, 218 were excluded due to not matching the inclusion criteria. RESULTS: A total of 185 relevant articles were identified matching the search criteria for an overview of the current literature on the laparoscopic surgery. Articles covered the period from the first laparoscopic application through its tremendous advancement over the last several years. Overall, the biggest advantage of the procedure has been minimizing trauma to the abdominal wall compared with open surgery. In the case of cholecystectomy, fundoplication, and adrenalectomy, the procedure has become the gold standard without being proven as a superior technique over the open surgery in randomized controlled trials. Faster recovery, reduced hospital stay, and a quicker return to normal activities are the most evident advantages of the laparoscopic surgery. Positive outcomes, efficiency, a lower rate of wound infections, and reduction in the perioperative morbidity of minimally invasive procedures have been shown in most indications. CONCLUSION: Improvements in surgical training and developments in instruments, imaging, and surgical techniques have greatly increased safety and feasibility of the laparoscopic surgical procedures.

The objective was to assess the results retrospectively in terms of complications and its limitations. Methods Between years 1998-2007, a two port laparoscopic assisted appendectomy was attempted in 2380 adult patients with suspected appendicitis. The patients with localized or generalized peritonitis were included. The appendicectomy was performed via an assisted two port method using 10 mm umbilical optical port and another 10 mm port in right iliac fossa. The children aged 12 and below and pregnant patients were excluded. All patients had their laparoscopic appendicectomy within 48 hours of admission. Results Two port laparoscopic assisted appendicectomy was successful in 86.9% of cases. Acute appendicitis was the cause of acute abdomen in 88.9% of the patients. The accessory port was required in 8.5% of patients to complete the appendicectomy and the conversion rate to open was 4.6%. The mean operation time was 25 minutes and the mean hospital stay was 1.5 days. The port site infection was seen in 14, bleeding in 20, parietal wall abscess in three cases and intra-abdominal abscesses in 4 patients. Conclusion This approach is simple, can be converted to total intracorporeal by inserting accessory port or to open appendicectomy when required and has advantage of full laparoscopy of abdomen. It has its limitations in cases of extreme obesity, thick mesentery, gangrenous appendix, very large and thick appendix, and difficulty in finding the appendix, control of bleeding, division of adhesions and to deal with other associated pathology. Cost was minimized by using non-disposable port. The overall morbidity was low. There were no specific complications related to this technique and incidence of port site infection was similar to other approaches of laparoscopic appendicectomy. PMID:22359707

    Background and Objectives: The purpose of this study is to estimate the cumulative incidence, patient characteristics, and potential risk factors for secondary hemorrhage after total laparoscopic hysterectomy. Methods: All women who underwent total laparoscopic hysterectomy at Paul's Hospital between January 2004 and April 2012 were included in the study. Patients who had bleeding per vaginam between 24 hours and 6 weeks after primary surgery were included in the analysis. Results: A total of 1613 patients underwent total laparoscopic hysterectomy during the study period, and 21 patients had secondary hemorrhage after hysterectomy. The overall cumulative incidence of secondary hemorrhage after total laparoscopic hysterectomy was 1.3%. The mean size of the uterus was 541.4 g in the secondary hemorrhage group and 318.9 g in patients without hemorrhage, which was statistically significant. The median time interval between hysterectomy and secondary hemorrhage was 13 days. Packing was sufficient to control the bleeding in 13 patients, and 6 patients required vault suturing. Laparoscopic coagulation of the uterine artery was performed in 1 patient. Uterine artery embolization was performed twice in 1 patient to control the bleeding. Conclusions: Our data suggest that secondary hemorrhage is rare but may occur more often after total laparoscopic hysterectomy than after other hysterectomy approaches. Whether it is related to the application of thermal energy to tissues, which causes more tissue necrosis and devascularization than sharp culdotomy in abdominal and vaginal hysterectomies, is not clear. A large uterus size, excessive use of an energy source for the uterine artery, and culdotomy may play a role. PMID:25392609

    Background and Objectives: Rectal prolapse is often repaired laparoscopically, frequently with the use of reinforcement material. Both synthetic and biologically derived materials reduce recurrence rate compared to primary suture repair. Synthetic mesh introduces potential complications such as mesh erosion, fibrosis, and infection. Urinary bladder matrix (UBM) represents a biologically derived material for reinforcement of rectal prolapse repair with the potential to improve durability without risks of synthetic materials. The objective of the study is to evaluate the effectiveness, durability, and functional result of laparoscopic rectopexy using urinary bladder matrix xenograft reinforcement at three years follow up. Methods: The 20 cases presented describe rectal prolapse repair by means of laparoscopic rectopexy with presacral UBM reinforcement. Patients were followed up for an average of 3 years and assessed with interviews, physical examination, manometry, and the fecal incontinence severity index (FISI). Results: Each repair was completed laparoscopically. UBM exhibited favorable handling characteristics when sutured to the sacrum and the lateral rectal walls. One patient underwent laparoscopic drainage of a postoperative abscess; no other complications occurred. In 3 years of follow-up, there have been no full-thickness recurrences, erosions, reoperations, or long-term complications. Two patients exhibited a small degree of mucosal prolapse on follow-up physical examination that did not require surgery. Three-year FISI scores averaged 8 (range, 0–33 of a possible 61), indicating low fecal incontinence symptomatology. Follow-up anorectal manometry was performed in 9 patients, showing mixed results. Conclusion: Surgeons may safely use laparoscopic rectopexy with UBM reinforcement for repair of rectal prolapses. In this series, repairs with UBM grafts have been durable at 3-year follow-up and may be an alternative to synthetic mesh reinforcement of rectal

    AIM: To investigate the role of laparoscopy in the surgical management of hepatocellular adenoma (HA). METHODS: We reviewed a prospectively collected database of consecutive patients undergoing laparoscopic liver resection for HA. RESULTS: Thirteen patients underwent fifteen pure laparoscopic liver resections for HA (male/female: 3/10; median age 42 years, range 22-72 years). Two patients with liver adenomatosis required two different laparoscopic operations for ruptured adenomas. Indications for surgery were: symptoms in 12 cases, need to rule out malignancy in 2 cases and preoperative diagnosis of large HA in one case. Symptoms were related to bleeding in 10 cases, sepsis due to liver abscess following embolization of HA in one case and mass effect in one case (shoulder tip pain). Five cases with ruptured bleeding adenoma required emergency admission and treatment with selective arterial embolization. Laparoscopic liver resection was then semi-electively performed. Eight patients (62%) required major hepatectomy [right hepatectomy (n = 5), left hepatectomy (n = 3)]. No conversion to open surgery occurred. The median operative time for pure laparoscopic procedures was 270 min (range 135-360 min). The median size of the excised lesions was 85 mm (range 25-180 mm). One patient with adenomatosis developed postoperative bleeding requiring embolization. Mortality was nil. The median hospital stay was 4 d (range 1-18 d) with a median high dependency unit stay of 1 d (range 0-7 d). CONCLUSION: The laparoscopic approach represents a safe option for the management of HA in a semi-elective setting and when major hepatectomy is required. PMID:21860698

    Duplication of the gallbladder is a rare congenital anomaly of the gallbladder, with an estimated prevalence of 1–3 per 3800 individuals. Unless properly diagnosed preoperatively, it can lead to biliary tract injuries and postoperative complications which may require reoperative surgeries. While previously reported cases have been treated with conventional laparoscopic cholecystectomy (LC), treatment with single incision laparoscopic surgery (SILS) has not been reported yet. We herein present the case of a 58-year-old female with gallbladder duplication who was successfully treated with SILS cholecystectomy. PMID:26266074

    Intrahepatic subcapsular hematoma after laparoscopic cholecystectomy is a rare complication and is potentially life threatening. When radiologic studies confirm the presence of the hematoma, the decision to follow a conservative treatment should involve clinical monitoring. If there are signs of infection, the collection can safely be drained percutaneously. If there are signs of active bleeding, a selective embolization should be attempted first. If unsuccessful, subsequent surgical evacuation should be performed. We report the case of a patient with an intrahepatic subcapsular hematoma after laparoscopic cholecystectomy, which occurred 6 weeks after surgery, and review the literature concerning the management of these bleedings.

    Abdominal incisional hernia is a common complication after open abdominal operations. Laparoscopic procedures have obvious mini-invasive advantages for surgical treatment of abdominal incisional hernia, especially to cases with big hernia defect. Laparoscopic repair of incisional hernia has routine mode but the actual operations will be various according to the condition of every hernia. Key points of these operations include design of the position of trocars, closure of defects and fixation of meshes. The details of these issues and experiences of perioperative evaluation and treatment will be talked about in this article. PMID:27761446

    Of 61 consecutive patients undergoing laparoscopic cholecystectomy, 4 (6.25%) developed abdominal wall haematomas. This complication of laparoscopic cholecystectomy may occur more commonly than existing literature suggests, and manifests in the post-operative period (days 2 to 6) by visible bruising, excessive pain or an asymptomatic drop in haematocrit. It is readily confirmed by ultrasonography. While no specific treatment is necessary apart from replacement of significant blood loss, the patient requires reassurance that this apparently alarming complication will rapidly resolve.

    Background and Objectives: The purpose of this study was to analyze the surgical technique, postoperative complications, and possible recurrence after laparoscopic ventral hernia repair (LVHR) in comparison with open ventral hernia repair (OVHR), based on the international literature. Database: A Medline search of the current English literature was performed using the terms laparoscopic ventral hernia repair and incisional hernia repair. Conclusions: LVHR is a safe alternative to the open method, with the main advantages being minimal postoperative pain, shorter recovery, and decreased wound and mesh infections. Incidental enterotomy can be avoided by using a meticulous technique and sharp dissection to avoid thermal injury. PMID:26273186

    The management of Meckel diverticulum found unexpectedly during an abdominal operation remains controversial. Most published reports have included only patients undergoing diverticulectomy or bowel resection through laparotomy. We report a case of a carcinoid tumor in a Meckel’s diverticulum which was incidentally detected and removed during laparoscopic inguinal hernia repair. Although there is no compelling evidence in the literature to recommend prophylactic diverticulectomy, laparoscopic stapled resection represents a viable and safe approach in healthy individuals undergoing elective surgery for other purposes.

    Fibroepithelial polyps of the ureter are rare benign mesothelial tumors. Most polyps are small; however, very rare large polyps have also been reported. Currently, most investigators encourage endoscopic management in these patients. Nevertheless, endoscopic resection can be difficult in patients with a long or large polypoid lesion. We describe our experience and laparoscopic technique for treatment of a symptomatic 42-year-old woman who presented with a 17-cm-long fibroepithelial polyp in the proximal ureter associated with ureteral obstruction. To our knowledge, this is the first reported case of laparoscopic management of a large ureteral fibroepithelial polyp.

    Laparoscopic surgery is applied today worldwide to most digestive procedures. In some of them, such as cholecystectomy, Nissen's fundoplication or obesity surgery, laparoscopy has become the standard in practice. In others, such as colon or gastric resection, the laparoscopic approach is frequently used and its usefulness is unquestionable. More complex procedures, such as esophageal, liver or pancreatic resections are, however, more infrequently performed, due to the high grade of skill necessary. As a result, there is less clinical evidence to support its implementation. In the recent years, robot-assisted laparoscopic surgery has been increasingly applied, again with little evidence for comparison with the conventional laparoscopic approach. This review will focus on the complex digestive procedures as well as those whose use in standard practice could be more controversial. Also novel robot-assisted procedures will be updated.

    To investigate the value of laparoscopic virtual reality simulator in laparoscopic suture ability training of catechumen. After finishing the virtual reality training of basic laparoscopic skills, 26 catechumen were divided randomly into 2 groups, one group undertook advanced laparoscopic skill (suture technique) training with laparoscopic virtual reality simulator (virtual group), another used laparoscopic box trainer (box group). Using our homemade simulations, before grouping and after training, every trainee performed nephropyeloureterostomy under laparoscopy, the running time, anastomosis quality and proficiency were recorded and assessed. For virtual group, the running time, anastomosis quality and proficiency scores before grouping were (98 ± 11) minutes, 3.20 ± 0.41, 3.47 ± 0.64, respectively, after training were (53 ± 8) minutes, 6.87 ± 0.74, 6.33 ± 0.82, respectively, all the differences were statistically significant (all P < 0.01). In box group, before grouping were (98 ± 10) minutes, 3.17 ± 0.39, 3.42 ± 0.67, respectively, after training were (52 ± 9) minutes, 6.08 ± 0.90, 6.33 ± 0.78, respectively, all the differences also were statistically significant (all P < 0.01). After training, the running time and proficiency scores of virtual group were similar to box group (all P > 0.05), however, anstomosis quality scores in virtual group were higher than in box group (P = 0.02). The laparoscopic virtual reality simulator is better than traditional box trainer in advanced laparoscopic suture ability training of catechumen.

    Objective. To review the vaginal cuff complications from a large series of total laparoscopic hysterectomies in which the laparoscopic culdotomy closure was highly standardized. Methods. Retrospective cohort study (Canadian Task Force Classification II-3) of consecutive total and radical laparoscopic hysterectomy patients with all culdotomy closures performed laparoscopically was conducted using three guidelines: placement of all sutures 5 mm deep from the vaginal edge with a 5 mm interval, incorporation of the uterosacral ligaments with the pubocervical fascia at each angle, and, whenever possible, suturing the bladder peritoneum over the vaginal cuff edge utilizing two suture types of comparable tensile strength. Four outcomes are reviewed: dehiscence, bleeding, infection, and adhesions. Results. Of 1924 patients undergoing total laparoscopic hysterectomy, 44 patients (2.29%) experienced a vaginal cuff complication, with 19 (0.99%) requiring reoperation. Five patients (0.26%) had dehiscence after sexual penetration on days 30–83, with 3 requiring reoperation. Thirteen patients (0.68%) developed bleeding, with 9 (0.47%) requiring reoperation. Twenty-three (1.20%) patients developed infections, with 4 (0.21%) requiring reoperation. Three patients (0.16%) developed obstructive small bowel adhesions to the cuff requiring laparoscopic lysis. Conclusion. A running 5 mm deep × 5 mm apart culdotomy closure that incorporates the uterosacral ligaments with the pubocervical fascia, with reperitonealization when possible, appears to be associated with few postoperative vaginal cuff complications.

    Ribas-Silva, Rejane Cristina; Eid, Andressa Ahmad

    2012-01-01

    Background Dengue is an urban arbovirus whose etiologic agent is a virus of the genus Flavorius with four distinct antigen serotypes (DENV-1, DENV-2, DENV-3 and DENV-4) that is transmitted to humans through the bite of the mosquito Aedes aegypti. The Campo Mourão region in Brazil is endemic for dengue fever. Obtective The aim of this study was to evaluate the presence of IgG and IgM antibodies specific to the four serotypes of dengue in donors of the blood donor service in the city of Campo Mourão. Methods Epidemiological records were evaluated and 4 mL of peripheral blood from 213 blood donors were collected in tubes without anticoagulant. Serum was then obtained and immunochromatographic tests were undertaken (Imuno-Rápido Dengue IgM/IgGTM). Individuals involved in the study answered a social and epidemiological questionnaire on data which included age, gender and diagnosis of dengue. Results Only three (1.4%) of the 213 blood tests were positive for IgG anti-dengue antibodies. No donors with IgM antibody, which identifies acute infection, were identified. Conclusions The results of the current analysis show that the introduction of quantitative or molecular serological methods to determine the presence of anti-dengue antibodies or the detection of the dengue virus in blood donors in endemic regions should be established so that the quality of blood transfusions is guaranteed.

    Background Reports on unexpected events (UEs) during blood donation (BD) inadequately consider the role of technical UEs. Methods Defined local and systemic UEs were graded by severity; technical UEs were not graded. On January 1, 2008, E.B.P.S.-Logistics (EBPS) installed the UE module for plasma management software (PMS). Donor room physicians entered UEs daily into PMS. Medical directors reviewed entries quarterly. EBPS compiled data on donors, donations, and UEs from January 1, 2008 to June 30, 2011. Results 6,605 UEs were observed during 166,650 BDs from 57,622 donors for a corrected incidence of 4.30% (0.66% local, 1.59% systemic, 2.04% technical UEs). 2.96% of BDs were accompanied by one UE and 0.45% by >1 UE (2-4). 6.3% of donors donating blood for their first time, 3.5% of those giving blood for their second time, and 1.9% of donors giving their third or more BD experienced UEs. Most common UEs were: discontinued collections due to venous access problems, repeated venipuncture, and small hematomas. Severe circulatory UEs occurred at a rate of 16 per 100,000 BDs. Conclusions Technical UEs were common during BD. UEs accompanied first and second donations significantly more often than subsequent donations. PMID:26195932

    The current availability of lung donors is far exceeded by the number of potential transplant recipients who are waiting for an organ. This disparity results in significant morbidity and mortality for those on the waiting list. Although it is desirable to increase overall consent rates for organ donation, doing so requires an intervention to affect societal response. In contrast, increased procurement of organs from marginal donors and improved donor management may be realized through increased study and practice changes within the transplant community. Transplantation of organs from marginal or extended-criteria donors may result in some increase in complications or mortality, but this possibility must be weighed against the morbidity and risk of death risk faced by individuals on the waiting list. The effects of this trade-off are currently being studied in kidney transplantation, and perhaps in the near future lung transplantation may benefit from a similar analysis. Until that time, the limited data regarding criteria for donor acceptability must be incorporated into practice to maximize the overall benefits of lung transplantation.

    To evaluate the feasibility of performing laparoscopic radical prostatectomy (LRP) as a day case procedure while maintaining patient satisfaction and safety. Herein we report our experience, selection criteria, and discharge criteria for day case LRP. We performed a prospective study with 32 patients undergoing extraperitoneal LRP. These patients were counselled before the procedure that they would go home the same evening of the procedure. Pain scores and quality of life data were recorded day 1 postoperatively via a telephone consultation. The patients underwent routine blood tests on day 2 and an outpatient review on day 7 and regularly thereafter via an assigned key worker. Socio-demographic data, comorbidities, and outcomes were collected for analysis. All patients were successfully discharged the same day of surgery. Mean patient age was 62 years with a mean body mass index of 25. Mean operative time was 147 minutes, and estimated blood loss was 101 ml. Three patients were treated for post operative urinary tract infections; two patients developed infected lymphoceles which required percutaneous drainage and one patient required re-catheterisation due to a burst catheter balloon. Of these six complications four patients required re-admission. Post-operative pain, nausea and vomiting were low whilst patient satisfaction scores were unanimously high in all patients surveyed. The early experience with extraperitoneal LRP as a same day surgery is promising although patients who are at high risk of lymphocele should be excluded. Preoperative patient counselling and selection is paramount. Patient satisfaction is not adversely affected by the shortened stay. Surgeon experience, a well-motivated patient, meticulous attention to detail through an integrated pathway, a multidisciplinary team and adequate postoperative assessment are essential.

    Disposable trocars with safety shields are widely used for laparoscopic access. The aim of this study was to analyze risk factors associated with injuries resulting from their use as reported to the Food and Drug Administration. Manufacturers are required to report medical device-related incidents to the Food and Drug Administration. We analyzed the 629 trocar injuries reported from 1993 through 1996. There were three types of injury: 408 injuries of major blood vessels, 182 other visceral injuries (mainly bowel injuries), and 30 abdominal wall hematomas. Of the 32 deaths, 26 (81%) resulted from vascular injuries and 6 (19%) resulted from bowel injuries. Eighty-seven percent of deaths from vascular injuries involved the use of disposable trocars with safety shields and 9% involved disposable trocars with a direct-viewing feature. The aorta (23%) and inferior vena cava (15%) were the vessels most commonly traumatized in the fatal vascular injuries. Ninety-one percent of bowel injuries involved trocars with safety shields and 7% involved direct-view trocars. The diagnosis of an enterotomy was delayed in 10% of cases, and the mortality rate in this group was 21%. In 41 cases (10%) the surgeon initially thought the trocar had malfunctioned, but in only 1 instance was malfunction subsequently found when the device was examined. The likelihood of injury was not related to any specific procedure or manufacturer. These data show that safety shields and direct-view trocars cannot prevent serious injuries. Retroperitoneal vascular injuries should be largely avoidable by following safe techniques. Bowel injuries often went unrecognized, in which case they were highly lethal. Device malfunction was rarely a cause of trocar injuries.

    Cost has been perceived to be a factor limiting the development of laparoscopic colorectal surgery. This study aimed to compare the costs of laparoscopic and open colorectal surgery. Patients undergoing laparoscopic or open elective colorectal surgery were recruited into a prospective study to evaluate the healthcare costs of each operative procedure in a district general hospital in England. All healthcare resources used (operation, hospital and community) were recorded and converted to costs in British pounds, 2006-2007. Costs of laparoscopic and open surgery were compared. In all, 201 consecutive patients consented and were recruited (131 laparoscopic, 70 open). Operative costs were greater in the laparoscopic group (£2049 vs£1263, P < 0.001) due to the costs of disposable instruments, but the hospital costs were less (£1807 vs£3468, P < 0.001) due to longer lengths of stay in the open group. Community costs were similar in the two groups and had little impact on the overall costs, which were not significantly different (£3875 laparoscopic vs£4383 open, P = 0.308). In the subgroup of patients with a stoma, overall costs in the laparoscopic group are higher (not significant). The costs of laparoscopic and open colorectal surgery are broadly equivalent. If there is an associated improvement in patient benefit, then laparoscopic colorectal surgery may be considered to be cost effective compared with open surgery. © 2012 The Authors.

    To improve visualization during minimal access surgery, a novel robotic camera has been developed. The prototype camera is totally insertable, has 5 degrees of freedom, and is remotely controlled. This study compared the performance of laparoscopic surgeons using both a laparoscope and the robotic camera. The MISTELS (McGill Inanimate System for the Training and Evaluation of Laparoscopic Skill) tasks were used to test six laparoscopic fellows and attending surgeons. Half the surgeons used the laparoscope first and half used the robotic camera first. Total scores from the MISTELS sessions in which the laparoscope was used were compared with the sessions in which the robotic camera was used and then analyzed with a paired t test (P < .05 was considered significant). All six surgeons tested showed no significant difference in their MISTELS task performance on the robotic camera compared with the standard laparoscopic camera. The mean MISTELS score of 963 for all subjects who used a laparoscope and camera was not significantly different than the mean score of 904 for the robotic camera (P = .17). This new robotic camera prototype allows for equivalent performance on a validated laparoscopic assessment tool when compared with performance using a standard laparoscope.

    Purpose: To evaluate outcomes including operating time, blood loss, length of stay (LOS), return to work and complications of laparoscopic hysterectomy performed with automatic stapling devices. Methods: Between 6/11/91 and 11/23/95, 127 laparoscopic hysterectomies were performed with automatic stapling devices. On an average, 6 firings with the stapler were done per case. Postoperative telephone survey and retrospective review of records were done. Results: Data averages for operating time, blood loss, LOS and return to work, respectively, were 90 minutes, 190 cc's, 1.1 day and 2 weeks. Significant complications included delayed postoperative bleeding in 4 patients, all of which occurred within the first 35 cases. One was controlled laparoscopically and 3 others required exploratory laparotomies. Since certain precautionary measures as described were taken, hemorrhagic complications were eliminated. Conclusions: Laparoscopic hysterectomy can be performed safely and effectively with automatic stapling devices in properly selected patients. A potential hazard inherent with this technique includes intraoperative and postoperative bleeding from the staple lines, the incidence of which can be minimized by taking certain precautionary measures such as the use of white cartridges only and bipolar desiccation of staple lines when indicated.

    Introduction The differential outcomes of laparoscopic adrenalectomy are not well described. Therefore, we evaluated these outcomes in the 3 groups most often seen clinically: bilateral adrenalectomy for Cushing's disease (group 1), pheochromocytoma (group 2) and unilateral adrenalectomy for non-pheochromocytoma (group 3). Methods We reviewed a longitudinal database of 72 consecutive cases of laparoscopic adrenalectomy carried out between 1997 and 2001 at the Centre for Minimally Invasive Surgery, University of Toronto. Results Patients in group 1 tended to be older (median 49 yr) and heavier (median 87 kg). They had a longer operating time (median 255 min), more postoperative complications (15%) and a longer median postoperative stay (4 d). Patients in group 2 had intermediate outcomes: a median operating time of 198 minutes, complication rate of 8.3% and a median postoperative hospital stay of 3 days. However, they had more intraoperative blood loss (median 150 mL). Group 3 patients had the best outcomes with the shortest median operating time (125 min), least blood loss (median 50 mL), fewer complications (6%) and shortest hospital stay (median 2 d). Conclusions Although the outcomes of laparoscopic adrenalectomy are uniformly good, on the basis of the underlying pathologic characteristics, patients can be divided into groups that have different expected outcomes. Patients requiring a unilateral adrenalectomy except for pheochromocytoma have the best recorded outcomes. Surgeons transferring to laparoscopic adrenalectomy would benefit from selecting patients in this group during their learning curve. PMID:14577705

    To report a case of uncommon endometriosis located in the Nuck's duct and its laparoscopic resolution. Case report. Gynecologic department at 12 de Octubre University Hospital, Madrid. A 35-year-old woman, gravida 1 para 1, presented with an inguinal right mass. She had a right nephrectomy because of acute pyelonephritis. Computed tomography showed a cystic lesion that was suggestive of a Nuck's duct cyst. Fine-needle aspiration cytology was performed, and endometriosis was determined. Cyst removal and closure of the internal inguinal ring's defect by the laparoscopic approach. Disease free. The intervention was successfully performed by laparoscopic approach. The postoperative evolution was good, and the patient was discharged 2 days after surgery. Inguinal or Nuck's duct are both uncommon locations for endometriosis; therefore, it is difficult to suspect in patients without a surgical history. Once identified, the treatment involves removal of the endometrioma and repair of the internal inguinal ring. A laparoscopic approach should be considered when possible.

    Patients with high grade and/or muscle invasive bladder cancer and with concomitant diseases of the upper urinary tract, e.g. urothelial tumors (transitional cell carcinoma – TCC) or afunctional hydronephrotic kidneys, may be candidates for simultaneous cystectomy and nephroureterectomy. Although the progress in laparoscopic techniques made these procedures feasible and safe, they are still technically demanding so only experienced surgeons can perform them. The aim of the study is to report our experience with laparoscopic simultaneous en bloc resection of the urinary bladder together with unilateral or bilateral nephroureterectomy in patients with TCC. Our material consists of three cases operated on in three centers between 2002 and 2011. After having completed bilateral (1 case) or unilateral (2 cases) nephroureterectomy, we performed radical cystectomy with pelvic lymph node dissection. All the specimens, including the kidneys, ureters, bladder, and reproductive organs in the female, were collected in endobags and were retrieved en bloc using hypogastric incision in the male patient and the vaginal route in the female patients. The demographic and perioperative information was collected and analyzed. All procedures were completed laparoscopically without the need of conversion to open surgery. No major intra- or postoperative complications were observed. Only 1 patient suffered from prolonged lymphatic leakage. From our experience we can conclude that single-session laparoscopic cystectomy and nephroureterectomy are technically feasible and safe, and may be offered for the treatment of selected cases of TCC of the urinary tract.

    Objective: This retrospective observational report analyzes the demographics, blood loss, length of surgical duration, number of days in the hospital, and complications for 821 consecutive patients undergoing total laparoscopic hysterectomy over a 11-year period stratified by incidental appendectomy. Methods: A retrospective chart abstraction was performed. ANOVA and chi-square tests were performed with significance preset at P<0.05. Results: Of 821 consecutive patients undergoing total laparoscopic hysterectomy, 257 underwent elective appendectomy with the ultrasonic scalpel, either as part of their staging, treatment for pelvic pain, or prophylaxis against appendicitis. Comparing the 2 groups, no difference existed in mean age of 50±10 years or mean BMI of 27.6±6.7. Both groups had a similar mean blood loss of 130 mL. Surgery took less time (137 vs 118 minutes, P<0.0012) and the hospital stay was shorter in the appendectomy group (1.5 vs 1.2, P<0.0001) possibly because it was performed incidentally in most cases. No complications were attributable to the appendectomy, and complication types and rates in both groups were similar. Though all appendicies appeared normal, pathology was documented in 9%, including 3 carcinoid tumors. Conclusions: Incidental appendectomy during total laparoscopic hysterectomy is not associated with significant risk and can be routinely offered to patients planning elective gynecologic laparoscopic procedures, as is standard for open procedures.

    Human perceptual capabilities related to the laparoscopic interaction paradigm are not well known. Its study is important for the design of virtual reality simulators, and for the specification of augmented reality applications that overcome current limitations and provide a supersensing to the surgeon. As part of this work, this article addresses the study of laparoscopic pulling forces. Two definitions are proposed to focalize the problem: the perceptual fidelity boundary, limit of human perceptual capabilities, and the Utile fidelity boundary, that encapsulates the perceived aspects actually used by surgeons to guide an operation. The study is then aimed to define the perceptual fidelity boundary of laparoscopic pulling forces. This is approached with an experimental design in which surgeons assess the resistance against pulling of four different tissues, which are characterized with both in vivo interaction forces and ex vivo tissue biomechanical properties. A logarithmic law of tissue consistency perception is found comparing subjective valorizations with objective parameters. A model of this perception is developed identifying what the main parameters are: the grade of fixation of the organ, the tissue stiffness, the amount of tissue bitten, and the organ mass being pulled. These results are a clear requirement analysis for the force feedback algorithm of a virtual reality laparoscopic simulator. Finally, some discussion is raised about the suitability of augmented reality applications around this surgical gesture.

    We assessed the role of laparoscopic management in patients following spontaneous retroperitoneal hemorrhage from a renal tumor. A retrospective chart review revealed 4 patients with spontaneous retroperitoneal hemorrhage treated at our institution in the last 2 years. After conservative management elsewhere patients were referred for definitive therapy. Patient characteristics and tumor size were examined and correlated with ease of surgical dissection and surgical outcome. No patient had any history of trauma. Computerized tomography was used to identify the initial extent of hemorrhage in all patients. All patients underwent successful laparoscopic exploration without the need for open conversion. Three patients underwent radical nephrectomy and 1 underwent laparoscopic partial nephrectomy. Renal hemorrhage extending outside of the renal capsule was associated with significantly more adhesions than renal hemorrhage confined to the renal capsule. Mean patient age was 56 years (range 36 to 70). Mean retroperitoneal tumor size was 5.3 cm (range 2.5 to 10). Three renal hematomas were extracapsular and 1 was subcapsular. Mean operative time was 182.3 minutes (range 59 to 235). Average estimated blood loss was 800 cc (range 150 to 2,100). Nontraumatic retroperitoneal hemorrhage of renal origin may be managed using traditional laparoscopic techniques with results similar to those achieved with open renal exploration. These cases may prove technically challenging due to fibrosis and associated tissue plane loss.

    Purpose The aim of this study was to verify that laparoscopic resection for treating retroperitoneal benign neurilemmoma (NL) is expected to be favorable for complete resection of tumor with technical feasibility and safety. Methods We retrospectively analyzed 47 operations for retroperitoneal neurogenic tumor at Yonsei University College of Medicine, Severance Hospital and Gangnam Severance Hospital between January 2005 and September 2015. After excluding 21 patients, the remaining 26 were divided into 2 groups: those who underwent open surgery (OS) and those who underwent laparoscopic surgery (LS). We compared clinicopathological features between the 2 groups. Results There was no significant difference in operation time, estimated blood loss, transfusion, complication, recurrence, or follow-up period between 2 groups. Postoperative hospital stay was significantly shorter in the LS group versus the OS group (OS vs. LS, 7.00 ± 3.43 days vs. 4.50 ± 2.16 days; P = 0.031). Conclusion We suggest that laparoscopic resection of retroperitoneal benign NL is feasible and safe by obtaining complete resection of the tumor. LS for treating retroperitoneal benign NL could be useful with appropriate laparoscopic technique and proper patient selection. PMID:28289669

    Background and Objectives: Laparoscopic inguinal hernia repair has become increasingly popular as an alternative to open surgery. The purpose of this study was to evaluate the safety and effectiveness of the laparoscopic total extraperitoneal procedure with the use of staple fixation and polypropylene mesh. Methods: A retrospective chart review examined outcomes of 1240 laparoscopic hernia operations in 783 patients, focusing on intraoperative and early postoperative complications, pain, and time until return to work and normal physical activities. Results: There were no intraoperative complications in this series; 106 patients experienced early postoperative complications across 8 evaluated categories: urinary retention (4.1%), seroma (3.0%), testicular/hemiscrotal swelling (1.9%), testicular atrophy (0%), hydrocele (0.6%), mesh infection (0.1%), and neurological symptoms (transient, 1.0%; persistent, 0.2%). Patients used an average of 5.6 Percocet pills after the procedure, and mean times until return to work and normal activities, including their routine exercise regimen, were 3.0 and 3.8 days, respectively. Conclusion: Complication rates and convalescence times were considered equivalent or superior to those found in other studies assessing both laparoscopic and open techniques. The usage of multiple Endostaples did not result in increased neurologic complications in the early postoperative period when compared with findings in the literature. In the hands of an experienced surgeon, total extraperitoneal repair is a safe, effective alternative to open inguinal hernia repair. PMID:27493471

    The introduction of laparoscopic surgery (LS) can be considered the most important advancement in our specialty in the past 25 years. Despite its advantages, implementation and consolidation has not been homogenous, especially for advanced techniques. The aim of this study was to analyse the level of development and use of laparoscopic surgery in Spain at the present time and its evolution in recent years. During the second half of 2012 a survey was developed to evaluate different aspects of the implementation and development of LS in our country. The survey was performed using an electronic questionnaire. The global response rate was 16% and 103 heads of Department answered the survey. A total of 92% worked in the public system. A total of 99% perform basic laparoscopic surgery and 85,2% advanced LS. Most of the responders (79%) consider that the instruments they have available for LS are adequate and 71% consider that LS is in the right stage of development in their environment. Basic laparoscopic surgery has developed in our country to be considered the standard performed by most surgeons, and forms part of the basic surgical training of residents. With regards to advanced LS, although it is frequently used, there are still remaining areas of deficit, and therefore, opportunities for improvement. Copyright © 2013 AEC.

    2012-01-01

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

    Background Gastrointestinal mesenchymal or stromal tumors (GIST) are lesions originated on digestive tract walls, which are treated by surgical resection. Several laparoscopic techniques, from gastrectomies to segmental resections, have been used successfully. Aim Describe a single center experience on laparoscopic GIST resection. Method Charts of 15 operated patients were retrospectively reviewed. Thirteen had gastric lesions, of which ten were sub epithelial, ranging from 2-8 cm; and three were pure exofitic growing lesions. The remaining two patients had small bowel lesions. Surgical laparoscopic treatment consisted of two distal gastrectomies, 11 wedge gastric resections and two segmental enterectomies. Mechanical suture was used in the majority of patients except on six, which underwent resection and closure using manual absorbable sutures. There were no conversions to open technique. Results Mean operative time was 1h 29 min±92 (40-420 min). Average lenght of hospital stay was three days (2-6 days). There were no leaks, postoperative bleeding or need for reintervention. Mean postoperative follow-up was 38±17 months (6-60 months). Three patients underwent adjuvant Imatinib treatment, one for recurrence five months postoperatively and two for tumors with moderate risk for recurrence . Conclusion Laparoscopic GIST resection, not only for small lesions but also for tumors above 5 cm, is safe and acceptable technique. PMID:27120729

    Objectives In Oman, the most frequent indication for a splenectomy in children is sickle cell disease (SCD), which is one of the most common haematological disorders in the Gulf region. This study aimed to describe paediatric laparoscopic splenectomies alone for SCD at a tertiary hospital in Oman. Methods This study was conducted between February 2010 and October 2015 at the Sultan Qaboos University Hospital, Muscat, Oman. The medical records of all children aged ≤15 years old undergoing splenectomies during the study period were reviewed. Results A total of 71 children underwent laparoscopic splenectomies during the study period; of these, 50 children (28 male and 22 female) underwent laparoscopic splenectomies alone for SCD. The children’s weight ranged between 11–43 kg. The most common indication for a splenectomy was a recurrent splenic sequestration crisis (92%). Surgically removed spleens weighed between 155–1,200 g and measured between 9–22 cm. Operative times ranged between 66–204 minutes and intraoperative blood loss ranged between 10–800 mL. One patient required conversion to an open splenectomy. Postoperative complications were noted in only four patients. The median hospital stay duration was three days. Conclusion Among this cohort, the mean operating time was comparable to that reported in the international literature. In addition, rates of conversion and postoperative complications were very low. These findings indicate that a laparoscopic splenectomy alone in paediatric patients with SCD is a feasible option. PMID:28003896

    2010-01-01

    Background and Objectives: Pyogenic liver abscesses are mainly treated by percutaneous aspiration or drainage under antibiotic cover. If interventional radiology fails, surgical drainage becomes necessary. Recently, we performed laparoscopic liver abscess drainage successfully, and we aimed to focus on the topic in light of a systematic review of the literature. Methods: A 22-year-old man was admitted with a 4.5-cm multiloculated abscess in the left lobe of the liver. The abscess did not resolve with antibiotic-alone therapy. Percutaneous aspiration was unsuccessful due to viscous and multiloculated contents. Percutaneous catheter placement was not amenable. Laparoscopic abscess drainage was preferred over open abscess drainage. We used 3 trocars, operation time was 40 minutes, and blood loss was minimal. In the mean time, we searched PubMed using the key words [(liver OR hepatic) abscess*] AND [laparoscop* OR (minimal* AND invasiv*)]. Results: Postoperative recovery of the patient was uneventful, and the patient was asymptomatic after 3 months of follow-up. In the literature search, we found 53 liver abscesses (51 pyogenic and 2 amebic) that were treated by laparoscopy. Mean success rate was 90.5% (range, 85% to 100%) and conversion rate was zero. Conclusion: Treatment of liver abscess is mainly percutaneous drainage. Laparoscopic drainage should be selected as an alternative before open drainage when other modalities have failed.

    Transplantation technology has been refined in recent years and now offers hope to pediatric patients with a variety of end stage disease processes. The lack of available donors for the smallest potential organ recipients has led to the suggestion that anencephalic infants be used as organ donors. This suggested policy is contrary to current law and raises fundamental ethical issues relating to the definition of death and the treatment of the dying. The technical issues in the potential organ supply from this source are described and the opposing ethical positions developing in this debate are discussed.

    The aim of the study was to evaluate the experience of the Centre-Sud Transplant Organization (OCST) area using cadaveric donor with neoplastic diseases to evaluate the possibility of transmission to recipients. From January 1, 2003, to December 31, 2010, the neoplastic risk has been reported to be 5.4% (377/4654 referred donors). In 2003, the number of donors with a tumor and their mean age were respectively: 60 (10.3%) and 59.6 ± 19.9; 2004: 33 (5.2%) and 61.4 ± 15.9; 2005: 32 (6%) and 62.8 ± 15.5; 2006: 46 (7%) and 60.7 ± 19.1; 2007: 51 (7%) and 58.9 ± 16; in 2008: 58 (7%) and 59.7 ± 19.6; 2009: 47 (7%) and 57 ± 26; 2010: 49 (7%) and 64 ± 16. The organ most affected by tumor has been the central nervous system (18%). The tumor was diagnosed before in 325 (86%) cases, versus during organ retrieval in 48 (12.7%) donor operations but before, which four cases (1%) occured after transplantation. According to the histological types and grades, 28 evaluated donors (8.2%) were suitable for transplantation. The histological types were: thyroid carcinoma (n = 3); prostate carcinoma (n = 8), renal clear cell carcinoma (n = 7), oncocytoma (n = 1), meningiomas (n = 2), dermofibrosarcoma (n = 1); verrucous carcinoma of the vulva (n = 1), colon adenocarcinoma (n = 1), grade II astrocytoma (n = 1), adrenal gland tumor (n = 1), gastric GIST (n = 1), oligodendroglioma (n = 1). Forty-five organs were retrieved (22 livers, 19 kidneys, 3 hearts, and 1 pancreas) and transplanted into 44 recipients with 1 liver-kidney combined transplantation. Four recipients died due to causes not related to the tumor. No donor-transmitted tumor was detected among the recipients. Donation is absolutely not indicated in cases of tumors with high metastatic potential and high grades. Performing an accurate evaluation of the donor, taking into account the histological grade, currently can allow, organ retrieval and transplantation with an acceptable risk.

    Objective Laparoscopic sleeve gastrectomy is a widely accepted and effective bariatric surgery method. The rate of leakage at the staple-line has been reported to be between 1.5 and 5%. Aside from the use of percutaneous drainage, re-laparoscopy, or abdominal sepsis control by laparotomy, endoscopic esophagogastric stent placement is increasingly preferred as a treatment method. Because laparoscopic sleeve gastrectomy is a widely used modality in our hospital, we aimed to evaluate the rate of leaks and the results of stent placements in our patients. Material and Methods Between January 1st 2010 and August 31st 2014, laparoscopic sleeve gastrectomy was performed on 236 patients by three surgeons. The demographic information and postoperative discharge summaries were collected and analyzed with the permission of the hospital ethics committee. Information about leak treatment management was also collected. Results Leaks after laparoscopic sleeve gastrectomy in four patients were stented in the first postoperative month. Short (12 cm) Hanora® (M.I.Tech, Gyeonggi-do, Korea) self-expandable coated stents were placed in two patients, and long (24 cm) Hanora® self-expandable coated stents were placed in the other two. The stents were removed after one month in two patients, two and a half months later in one, and five months later in another patient. The leaks were demonstrated to be healed in all patients after stent removal. Endoscopic stent revision was performed in one patient due to migration of the stent and in another for stent breakage. Conclusion The success rate of treatment of leaks after laparoscopic sleeve gastrectomy by stent placement has been variable in the literature. The success in early stent placement has been shown to be related to physician expertise. According to the results of our patients, we suggest that endoscopic stent placement in the early stage after controlling sepsis is an effective method in the management of leaks. PMID:28149125

    To describe a laparoscopic technique for evaluating umbilical disorders in calves, including feasibility, visualization of umbilical structures, and related complications. Prospective clinical study. Male calves (15 Holstein, 2 Montbeliard) with umbilical disorders (n=17). Calves <2 months old with obvious umbilical disease were assessed by clinical examination and ultrasonography of the umbilical structures. Laparoscopic evaluation was performed in dorsal recumbency under subarachnoid lumbosacral anesthesia and sedation. An open insertion technique with short 60 mm cannulas was used after creating 2 portals 10 cm cranial to the umbilicus (one 5 cm left of midline for the laparoscope and one 5 cm right of midline as an instrument portal). After laparoscopy, abnormal tissues were resected by laparotomy during the same anesthetic period. Laparoscopic evaluation of umbilical structures was performed quickly (mean surgery time 7.1 ± 2.5 minutes). Umbilical structures could be completely visualized in all calves without intraoperative complications. In addition to abnormalities previously detected on ultrasound, laparoscopy enabled detection of adhesions 7 calves that were not suspected on ultrasound, as well as focal enlargements of the umbilical arteries and urachus close to the bladder in 5 calves. Laparoscopy failed to detect abnormalities observed with ultrasound or laparotomy in 4 calves, including small hernias and omphalitis. Laparoscopic evaluation of umbilical structures was performed safely and quickly in young calves and allowed complete evaluation of intra-abdominal umbilical structures and may, therefore, be a useful adjunct to physical examination and ultrasound to fully assess the abdomen in calves. © Copyright 2016 by The American College of Veterinary Surgeons.

    The advent of laparoscopic surgery has created new technical challenges and problems. Recently, a new commercially available vessel-sealing technology, the Ligasure system, was introduced. The aim of our study was to compare the effectiveness of this new system with earlier methods in a group of patients affected by renal-cell carcinoma. A series of 30 patients underwent laparoscopic radical nephrectomy for clinically localized renal-cell carcinoma. We always used a transperitoneal approach with a three-trocar technique. Patients were randomly divided in two groups: 15 underwent conventional laparoscopic radical nephrectomy, while 15 underwent laparoscopic nephrectomy using the Ligasure system, which is a bipolar radiofrequency generator. Information analyzed included intraoperative blood loss, operative time, conversion rate, and postoperative course. Statistical analysis was performed with commercially available software. The two groups were compared in term of clinical and pathologic variables using Student's t-test. Differences were considered significant at p < 0.05. No statistically significant differences were observed between the two groups for baseline characteristics. No conversion occurred in either group. Statistically significant differences were observed between conventional and Ligasure nephrectomy regarding mean intraoperative blood loss (485 mL and 100 mL, respectively; p < 0.05) and mean operative time (164 minutes and 68 minutes, respectively p < 0.05). No statistically difference was observed in the postoperative discharge time. The Ligasure vessel-sealing system seems to produce a consistent, reliable, permanent seal of veins, arteries, and tissue bundles by fusing the collagen in vessel walls. By reducing sutures and the number of instrument exchanges in the operating theatre, the Ligasure decreases operating time and blood loss. This new energy-based vessel-ligation device appears to be effective in advanced laparoscopic procedures.

    Conventional laparoscopes provide a flat representation of the three-dimensional (3D) operating field and are incapable of visualizing internal structures located beneath visible organ surfaces. Computed tomography (CT) and magnetic resonance (MR) images are difficult to fuse in real time with laparoscopic views due to the deformable nature of soft-tissue organs. Utilizing emerging camera technology, we have developed a real-time stereoscopic augmented-reality (AR) system for laparoscopic surgery by merging live laparoscopic ultrasound (LUS) with stereoscopic video. The system creates two new visual cues: (1) perception of true depth with improved understanding of 3D spatial relationships among anatomical structures, and (2) visualization of critical internal structures along with a more comprehensive visualization of the operating field. The stereoscopic AR system has been designed for near-term clinical translation with seamless integration into the existing surgical workflow. It is composed of a stereoscopic vision system, a LUS system, and an optical tracker. Specialized software processes streams of imaging data from the tracked devices and registers those in real time. The resulting two ultrasound-augmented video streams (one for the left and one for the right eye) give a live stereoscopic AR view of the operating field. The team conducted a series of stereoscopic AR interrogations of the liver, gallbladder, biliary tree, and kidneys in two swine. The preclinical studies demonstrated the feasibility of the stereoscopic AR system during in vivo procedures. Major internal structures could be easily identified. The system exhibited unobservable latency with acceptable image-to-video registration accuracy. We presented the first in vivo use of a complete system with stereoscopic AR visualization capability. This new capability introduces new visual cues and enhances visualization of the surgical anatomy. The system shows promise to improve the precision and

    Vascular injuries during laparoscopic cholecystectomy can occur similar to biliary injuries and mostly represented by intraoperative bleeding. Hepatic artery system pseudoaneurysm are rare. It occurs in the early or late postoperative course. Patients present with pallor, signs of haemobillia and altered liver function. We report a case of right posterior sectoral artery pseudoaneurysm detected 2 weeks after laparoscopic cholecystectomy and successfully repaired laparoscopically. We also describe how laparoscopic pringle clamping saved the conversion. The actively bleeding right posterior sectoral artery pseudoaneurysm was diagnosed by CT angiogram. Embolisation, usually the treatment of choice, would have risked liver insufficiency as hepatic artery proper was at risk because the origin the bleeding artery was just after its bifurcation. Isolated right hepatic artery embolisation can also cause hepatic insufficiency. To our knowledge this is the first reported case of laparoscopic repair of post-laparoscopic cholecystectomy bleeding sectoral artery pseudoaneurysm. PMID:24501508

    Laparoscopic surgery has advanced remarkably in recent years, resulting in reduced morbidity and shorter hospital stay compared with open surgery. Despite challenges from the expanding array of laparoscopic procedures performed with the use of pneumoperitoneum on increasingly sick patients, anesthesia has remained largely unchanged. At present, most laparoscopic operations are usually performed under general anesthesia, except for patients deemed "too sick" for general anesthesia. Recently, however, several large, retrospective studies questioned the widely held belief that general anesthesia is the best anesthetic method for laparoscopic surgery and suggested that regional anesthesia could also be a reasonable choice in certain settings. This narrative review is an attempt to critically summarize current evidence on regional anesthesia for laparoscopic surgery. Because most available data come from large, retrospective studies, large, rigorous, prospective clinical trials comparing regional vs. general anesthesia are needed to evaluate the true value of regional anesthesia in laparoscopic surgery.

    Purpose: The purpose of this study was to compare the safety and efficacy of laparoscopic appendectomy versus open appendectomy at Baptist Hospital in Miami, Florida. Methods: A retrospective review was performed on all appendectomies performed at Baptist Hospital from October 1, 1994 to September 30, 1995. There were a total of 244 cases; 137 open appendectomies and 107 laparoscopic appendectomies. The cases were reviewed with regard to pathology, operating time, length of hospital stay and complications. Results: The pathologic findings at surgery were similar for the two groups. Concomitant pathology was more likely to be found laparoscopically than in open surgery. There was a greater percentage of ruptured appendices in surgery done via the open method. Operative time was slightly longer, but complications were less in the laparoscopic group. Length of stay was lower in the laparoscopic appendectomy group. Conclusions: Although very similar, our method of appendectomy favors the laparoscopic technique. PMID:9876696

    2010-02-01

    Laparoscopic adjustable gastric banding has become a popular bariatric restrictive procedure in the USA. The increasing popularity of the laparoscopic adjustable gastric band procedure could, in part, be related to the lower cost and lower morbidity compared with laparoscopic gastric bypass. Although its placement is related to a lower number of perioperative complications compared with laparoscopic gastric bypass, its morbidity may be substantial. Barrett's esophagus or esophageal intestinal metaplasia is a known complication of chronic gastro-esophageal reflux disease that, in rare occasions, progresses to dysplasia and esophageal adenocarcinoma. Barrett's esophagus, after laparoscopic adjustable gastric banding placement, is a rare but not unexpected complication after gastric band placement. The incidence of Barrett's esophagus after adjustable gastric banding is not known. We present a case of Barrett's esophagus as a result of laparoscopic adjustable gastric banding placement due to a chronically and highly restrictive gastric band in a former morbidly obese patient.

    Summary Background Reports on unexpected donor events (UEs) during preparatory plasmapheresis (PPP) are scarce, and rarely consider technical UEs. Methods Defined local and systemic UEs were graded by severity; technical UEs were not graded. On January 1, 2008, E.B.P.S.-Logistics (EBPS) installed the UE module for plasma management software (PMS). Donor room physicians entered UEs daily into the PMS. Medical directors reviewed entries quarterly. EBPS compiled data on donors, donations and UEs from January 1, 2008 to June 30, 2011. Results 66,822 UEs were observed during 1,107,846 PPPs for a corrected incidence of 6.55% (1.4% local, 0.55% systemic, 4.6% technical UEs). 3.36% of PPPs were accompanied by 1 UE and 1.18% by >1 UE (2-5). 13.7% of donors undergoing PPP for the first time, 9.7% of those having a second PPP and 4.0% of those having a third or more PPPs were associated with UEs. Most common UEs were repeated venipuncture, and broken-off collection due to venous access problems and small hematomas. Severe systemic UEs occurred at a rate of 36 per 100,000 PPPs. Conclusions Technical UEs were common with PPP. UEs accompanied first and second donations significantly more frequently than for subsequent donations. PMID:24847188

    Inflammatory bowel diseases are an ideal indication for the laparoscopic surgical approach as they are basically benign diseases not requiring lymphadenectomy and extended mesenteric excision; well-established surgical procedures are available for the conventional approach. Inflammatory alterations and fragility of the bowel and mesentery, however, may demand a high level of laparoscopic experience. A broad spectrum of operations from the rather easy enterostomy formation for anal Crohn’s disease (CD) to restorative proctocolectomies for ulcerative colitis (UC) may be managed laparoscopically. The current evidence base for the use of laparoscopic techniques in the surgical therapy of inflammatory bowel diseases is presented. CD limited to the terminal ileum has become a common indication for laparoscopic surgical therapy. In severe anal CD, laparoscopic stoma formation is a standard procedure with low morbidity and short operative time. Studies comparing conventional and laparoscopic bowel resections, have found shorter times to first postoperative bowel movements and shorter hospital stays as well as lower complication rates in favour of the laparoscopic approach. Even complicated cases with previous surgery, abscess formation and enteric fistulas may be operated on laparoscopically with a low morbidity. In UC, restorative proctocolectomy is the standard procedure in elective surgery. The demanding laparoscopic approach is increasingly used, however, mainly in major centers; its feasibility has been proven in various studies. An increased body mass index and acute inflammation of the bowel may be relative contraindications. Short and long-term outcomes like quality of life seem to be equivalent for open and laparoscopic surgery. Multiple studies have proven that the laparoscopic approach to CD and UC is a safe and successful alternative for selected patients. The appropriate selection criteria are still under investigation. Technical considerations are playing

    Laparoscopic surgery requires different abilities to open surgery, and is challenging to learn within the confines of the operating theatre. With the development of laparoscopic surgery in modern surgery, the importance in improving these skills is becoming an increasing focus of surgical training programmes. The assembly of the laparoscopic trainer and exercises was performed at the University of Sydney Clinical School located at Hornsby Hospital in Sydney, Australia. The objective was to design and construct a new concept smartphone box laparoscopic trainer that is affordable and replicable, and to demonstrate its usefulness in practising laparoscopic techniques to improve skills outside of the operating theatre. The trainer was constructed using a personal smartphone, cardboard box, video graphics array (VGA) adaptor, VGA cable and a computer screen. Laparoscopic instruments and materials used for simulated task exercises were obtained from the operating theatre. Simulated demonstrations of simple laparoscopic tasks included suture handling, instrument knot-tying and anastomotic suture techniques. The smartphone box trainer is inexpensive (approximately $60) and took less than 20 minutes to build. The cost was almost entirely for the VGA adaptor. The box trainer was light, portable and easily transported to any setting that provided a computer screen. It is an inexpensive, easy-to-assemble, replicable model that benefits from the advanced technology of personal smartphones, and can be easily accessed as a useful tool in learning and improving laparoscopic techniques.

    Peptic ulcer perforation is a common life-threatening emergency needing immediate intervention. Laparoscopic closure of perforation is now widely practiced over conventional open closure. This study aimed to compare laparoscopic peptic ulcer perforation closure with conventional open closure in terms of operative time, postoperative analgesia, complications, hospital stay, and return to routine activities. This unicentric, nonblinded, prospective, randomized study was carried out in 50 patients with peptic ulcer perforation who were randomly allocated to undergo either laparoscopic closure or open closure surgery with 25 patients in each group. The mean operative time (60 vs 90 min) was less in the laparoscopic group (p < 0.05). Postoperative analgesia requirements (1 vs 6 days) were also less in laparoscopic patients (p < 0.05). Complications (nil vs 6; p < 0.05) and hospital stay (3 vs 8 days) were less in laparoscopic patients (p < 0.05). Patients return to normal activities (5 vs 10 days; p < 0.05) earlier in laparoscopic perforation closure than in open closure. Our study has shown better outcomes and lesser morbidities with laparoscopic approach in terms of shorter operative time, shorter hospital stay, less analgesic requirements, and less wound infections. Patients also return to routine activities earlier with the laparoscopic approach. It is a safe alternative to open surgery and should be a preferred choice when there are no contraindications to laparoscopy.

    Laparoscopy has become a well-established alternative to open surgery for the management of many urologic tumors. Metastases at one of the port sites is not a common complication, though there are some reports of port site metastases after laparoscopic management for renal tumors and pelvicaliceal tumors, as well as after laparoscopic lymphadenectomy. Herein, we report a case of port site metastases after robot-assisted laparoscopic radical cystectomy for muscle-invasive bladder cancer. To the best of our knowledge this is the first case of such pathology to be reported. Although rare, the laparoscopic surgeon should be aware of such complications when dealing with malignant masses.

    2012-08-01

    The advantage or disadvantage of laparoscopic appendectomy for acute appendicitis remains unclear. Data were collected prospectively from 129 consecutive patients with appendicitis between June 2008 and December 2009. The clinical outcomes of acute appendicitis after laparoscopic and open operation were compared. Furthermore, the outcomes of laparoscopic procedure for acute and chronic appendicitis were compared. The length of hospitalization and incidence of intra-abdominal abscess were significantly decreased in patients with laparoscopic group after operation as compared to open operation. The mean operation time, the time of first anal exsufflation, and oral intake after operation were longer for acute appendicitis patients than for chronic appendicitis in laparoscopic group. The incidence of postoperative intestinal obstruction in patients with acute appendicitis was higher after laparoscopic surgery than after open procedure. Laparoscopic appendectomy for acute appendicitis is feasible and safe. However, laparoscopic appendectomy for acute appendicitis might cause more postoperative complications including intra-abdominal abscess and small intestinal obstruction compared to laparoscopic appendectomy for chronic appendicitis. These complications could potentially be avoided by improving techniques in operation.

    Laparoscope manipulating robots are useful for maintaining a stable view during a laparoscopic operation and as a substitute for the surgeon who controls the laparoscope. However, there are several problems to be solved. A large apparatus sometimes interferes with the surgeon. The setting and repositioning is awkward. Furthermore, the initial and maintenance costs are expensive. This study was designed to develop a new laparoscope manipulating robot to overcome those problems. We developed a compact robot applicable for various types of laparoscopic surgery with less expensive materials. The robot was evaluated by performing an in vitro laparoscopic cholecystectomy using extracted swine organs. Then, the availability of the robot to various operations was validated by performing a laparoscopic cholecystectomy, anterior resection of the rectum, and distal gastrectomy using a living swine. The reliability of the system was tested by long-time continuous running. A compact and lightweight laparoscope manipulating robot by the name of P-arm was developed. The surgical time of an in vitro laparoscopic cholecystectomy with and without the P-arm was not different. The three types of operations were accomplished successfully. During the entire procedure, the P-arm worked without trouble and did not interfere with the surgeons. Continuous 8-h operating tests were performed three times and neither discontinuance nor trouble occurred with the system. The P-arm worked steadily for various swine operations, without interfering with surgeon's work.

In colorectal cancer, the safety of laparoscopic surgery, including the low incidence of port-site metastasis, has been proven in large, randomized trials. In gastric cancer, reports of port-site metastasis are extremely rare, but we should await the results of ongoing trials.

    What do identifiable sperm donors feel about psychosocial counselling? Identifiable sperm donors found it important that psychosocial counselling focused on emotional consequences and on rules and regulations and they expected to have access to psychosocial counselling at the time that donor-offspring actually sought contact. Most studies on sperm donors are on anonymous donors and focus on recruitment, financial compensation, anonymity and motivations. There is limited knowledge on the value that identifiable sperm donors place on psychosocial counselling and what their needs are in this respect. We performed a qualitative study from March until June 2014 with 25 identifiable sperm donors, who were or had been a donor at the Centre for Reproductive Medicine of the Academic Medical Centre in Amsterdam any time between 1989 and 2014. We held semi-structured in-depth interviews with identifiable sperm donors with an average age of 44 years. The interviews were fully transcribed and analysed using the constant comparative method of grounded theory. Twelve out of 15 donors (former donors ITALIC! n = 8, active donors ITALIC! n = 7) who had received a counselling session during their intake procedure found it important that they had been able to talk about issues such as the emotional consequences of donation, disclosure to their own children, family and friends, future contact with donor-offspring and rules and regulations. Of the 10 former donors who had received no counselling session, 8 had regretted the lack of intensive counselling. In the years following their donation, most donors simply wanted to know how many offspring had been born using their sperm and had no need for further counselling. Nevertheless, they frequently mentioned that they were concerned about the well-being of 'their' offspring. In addition, they would value the availability of psychosocial counselling in the event that donor-offspring actually sought contact. A limitation of our study is its

    Appendectomy, being the most common surgical procedure performed in general surgery, is still being performed by both open and laparoscopic methods due to a lack of consensus as to which is the most appropriate method. Because further trials are necessary and few such studies have been performed in developing countries, we decided to evaluate the outcomes of the 2 procedures to share our experience with the international community. Consecutive patients with suspected acute appendicitis who underwent laparoscopic (LA) (n=48) and open (n=52) appendectomy (OA) over a period of 3 years were studied. Clinical outcomes were compared between the 2 groups in relation to operative time, analgesia used, length of hospital stay, return to work, resumption of a regular diet, and postoperative complications. Mean age of patients was 25.8 years in the laparoscopic and 25.5 years in the open group. Patient demographics were similar in both groups (P>0.05). There was significantly less need for analgesia (1.0+/-0.5 in LA and 1.5+/-0.6 doses in OA), a short hospital stay (1.4+/-0.7 in LA and 3.4+/-1.0 days in OA), early return to work (12.6+/-3.3 in LA and 19.1+/-3.1 days in OA), and less time needed to return to a regular diet (20.1+/-2.9 in LA and 22.0+/-4.7, P<0.05 in OA) in the laparoscopic appendectomy group. Operative time was significantly shorter (54.9+/-14.7 in LA and 13.6+/-12.6 minutes in OA) in the open group. Total number of complications was less in the laparoscopic group; however, there was no statistically significant difference. The laparoscopic technique is a safe and clinically beneficial operative procedure. It provides certain advantages over open appendectomy, including short hospital stay, decreased requirement of postoperative analgesia, early food tolerance, and earlier return to normal activities. Where feasible, laparoscopy should be undertaken as the initial procedure of choice for most cases of suspected appendicitis.

  15. Laparoscopic Resection of Cesarean Scar Ectopic Pregnancy.

    PubMed

    Ades, Alex; Parghi, Sneha

    To demonstrate a technique for the laparoscopic surgical management of cesarean section scar ectopic pregnancy. Step-by-step presentation of the procedure using video (Canadian Task Force classification III). Cesarean section scar ectopic pregnancy is a rare form of ectopic pregnancy with an incidence ranging from 1:1800 to 1:2216. Over the last decade, the incidence seems to be on the rise with increasing rates of cesarean deliveries and early use of Doppler ultrasound. These pregnancies can lead to life-threatening hemorrhage, uterine rupture, and hysterectomy if not managed promptly. Local or systemic methotrexate therapy has been used successfully but can result in prolonged hospitalization, requires long-term follow-up, and in some cases treatment can fail. In the hands of a trained operator, laparoscopic resection can be performed to manage this type of pregnancy. Consent was obtained from the patient, and exemption was granted from the local Internal Review Board (The Womens' Hospital, Parkville). In this video we describe our technique for laparoscopic management of a cesarean scar ectopic pregnancy. We present the case of a 34-year-old G4P2T1 with the finding of a live 8-week pregnancy embedded in the cesarean section scar. The patient had undergone 2 previous uncomplicated cesarean sections at term. On presentation her β-human chorionic gonadotropin (β-hCG) level was 52 405 IU/L. She was initially managed with an intragestational sac injection of potassium chloride and methotrexate, followed by 4 doses of intramuscular methotrexate. Despite these conservative measures, the level of β-hCG did not adequately fall and an ultrasound showed a persistent 4-cm mass. A decision was made to proceed with surgical treatment in the form of a laparoscopic resection of the ectopic pregnancy. The surgery was uneventful, and the patient was discharged home within 24 hours of her procedure. Her serial β-hCG levels were followed until complete resolution

  18. Live donor transplantation--the incompetent donor: comparative law.

    PubMed

    Informed consent of the patient to medical treatment is an essential prerequisite for any invasive medical procedure. However in emergency cases, when the patient is unable to sign a consent form due to unconsciousness or to psychotic state, than the primary medical consideration shall take place. In such a case, in order to save life or even prevent a major medical hazard to the patient, doctors are allowed, in certain cases and in accordance with well accepted medical practice, to perform invasive procedures, major surgery or risky pharmacological treatment, without the explicit consent of the patient. All the above refers to the cases when avoidance of such non-consented treatment may harm severely the health and wellbeing of the patient and there is no doubt that such treatment is for the ultimate benefit of the patient. The question, however, shall arise when such a medical procedure is not necessarily for the benefit of the patient, but rather for the benefit of somebody else. Such is the case in the transplantation area and the question of living donor-donee relationship. This paper shall analyze the legal situation in cases of non competent donors whose consent cannot be considered legal consent given in full understanding and out of free will. It will also compare three legal systems, the Israeli, the American and the traditional Jewish law, with regard to the different approaches to this human problem, where the autonomy of the donor may be sacrificed for the purpose of saving life of another person.

    Laparoscopic surgery through a single incision is gaining popularity with different stakeholders. The advantages of improved cosmetics, decreased postoperative pain and blood loss continue to attract patients from different surgical fields. Multidisciplinary approach to different surgical entities through a single incision has just been introduced. We report the first case of a synchronous single-port access (SPA) laparoscopic right hemicolectomy and laparoscopic-assisted vaginal hysterectomy with bilateral salpingo-oophorectomy through a single incision above the umbilicus in a 48-year-old female with ascending colon mass and uterine mass with good postoperative outcomes. SPA laparoscopic surgery is feasible for multidisciplinary approach in resectable tumors. PMID:28096321

    Introduction: Adhesions are the reason for bowel obstruction in 80% of the cases. In well selected patients the adhesive ileus laparoscopic treatment has multiple advantages which include the shorter hospitalization period, earlier food taking, and less postoperative morbidity rate. Case report: Here we have a patient in the age of 35 hospitalized at the clinic due to occlusive symptoms. Two years before an opened appendectomy had been performed on him. He underwent the treatment of exploration laparoscopy and laparoscopic adhesiolysis. Dilated small bowel loops connected with the anterior abdominal wall in the ileocecal region by adhesions were found intraoperatively and then resected harmonically with scalpel. One strangulation around which a small bowel loop was wrapped around was found and dissected. Postoperative course was normal. PMID:27041815

  1. Carbon Dioxide Embolism during Laparoscopic Surgery

    Park, Eun Young; Kwon, Ja-Young

    2012-01-01

    Clinically significant carbon dioxide embolism is a rare but potentially fatal complication of anesthesia administered during laparoscopic surgery. Its most common cause is inadvertent injection of carbon dioxide into a large vein, artery or solid organ. This error usually occurs during or shortly after insufflation of carbon dioxide into the body cavity, but may result from direct intravascular insufflation of carbon dioxide during surgery. Clinical presentation of carbon dioxide embolism ranges from asymptomatic to neurologic injury, cardiovascular collapse or even death, which is dependent on the rate and volume of carbon dioxide entrapment and the patient's condition. We reviewed extensive literature regarding carbon dioxide embolism in detail and set out to describe the complication from background to treatment. We hope that the present work will improve our understanding of carbon dioxide embolism during laparoscopic surgery. PMID:22476987

    We report a case of minimally invasive surgery in the management of metastasis to the spleen. A 67-year-old male patient with possible splenic soft tissue melanoma metastasis was referred to our hospital. He had a history of an excised soft tissue melanoma from his back eight months earlier, and the control abdominal computer tomography (CT) scan revealed a hypodense spleen lesion. The patient underwent laparoscopic surgery to diagnose and treat the splenic lesion. The splenectomy was performed and the histological examination revealed a melanoma. The patient had a good postoperative course and was discharged on the second postoperative day. On his 12-month follow-up there was no sign of recurrence. The laparoscopic approach is a safe and effective alternative for treatment of splenic metastases. PMID:19547681

    The incidence of uterus didelphys is around 3/10,000 women. It is a class III Müllerian duct anomaly resulting from a complete non-fusion of the paired Müllerian ducts between the 12th and 16th weeks of gestation. Although the prevalence of cervical insufficiency in women with uterus didelphys is unknown, the incidence of cervical insufficiency in women with Müllerian anomalies has been reported as high as 30%. We present a case of successful pregnancy outcome following a laparoscopic transabdominal cerclage in a woman with uterus didelphys and cervical insufficiency. The case demonstrates that laparoscopic transabdominal cerclage can be performed successfully in women with uterus didelphys and a satisfactory obstetric outcome can be achieved.

    Laparoscopy reduces patient trauma but eliminates the surgeon's ability to directly view and touch the surgical environment. Although current robot-assisted laparoscopy improves the surgeon's ability to manipulate and visualize the target organs, the instruments and cameras remain constrained by the entry incision. This limits tool tip orientation and optimal camera placement. This article focuses on developing miniature in vivo robots to assist surgeons during laparoscopic surgery by providing an enhanced field of view from multiple angles and dexterous manipulators not constrained by the abdominal wall fulcrum effect. Miniature camera robots were inserted through a small incision into the insufflated abdominal cavity of an anesthetized pig. Trocar insertion and other laparoscopic tool placements were then viewed with these robotic cameras. The miniature robots provided additional camera angles that improved surgical visualization during a cholecystectomy. These successful prototype trials have demonstrated that miniature in vivo robots can provide surgeons with additional visual information that can increase procedural safety.

    Today, laparoscopic cholecystectomy is the method of choice for treatment of symptomatic gallbladder disorders. It minimizes effects of the operation that are independent of the gallbladder, such as trauma to the abdominal wall and other soft tissue. The surgical wounds were even smaller when 2-mm trocars were used. Laparoscopic cholecystectomy using 2-mm instruments was performed in a consecutive series of 14 patients with symptomatic gallstones. The procedure was completed in 12 cases, with conversion to open surgery in two cases. Intraoperative cholangiography was always performed. The postoperative course was always uneventful. The cosmetic effect was highly satisfactory. The procedure using 2-mm instruments could be indicated in selected patients with uncomplicated gallstone disease.

    Our experience is based on laparoscopic hysterectomies performs from August 1992 to May 1994. The purpose of the initial surgical objective is described, as well as different variations of the technique. The procedure was systematized, the operating time was diminished to a considerable extent, thus avoiding intra-operatory complications. Pre-operatory diagnosis and histopathological findings were enumerated. Intra-operatory and post-operatory complications were evaluated. With an increasing development of the technique, a shorter operating time was made possible. The length of hospital stay and its quality were unrelated to the operation time. A quick recovery was reached as regards complete activity of the patients. Laparoscopic hysterectomy performed by an endoscopic-gynecologist surgeon represents an alternative and a new way of thinking.

    We report a rare case of malignant hyperthermia during laparoscopic adjustable gastric banding. A 32-y-old female with no previous history of adverse reaction to general anesthesia underwent laparoscopic adjustable gastric banding. Intraoperative monitoring revealed a sharp increase in end-tidal carbon dioxide, autonomic instability, and metabolic and respiratory acidosis, along with other metabolic and biochemical derangements. She was diagnosed with malignant hyperthermia. Desflurane, the anesthetic agent was discontinued, and the patient was started on intravenous dantrolene. The surgery was completed, and the patient was brought to the surgical intensive care unit for continued postoperative care. She developed muscle weakness and phlebitis that resolved prior to discharge. Prompt diagnosis and treatment of malignant hyperthermia leads to favorable clinical outcome. This clinical entity can occur in the bariatric population with the widely used desflurane. Bariatric surgeons and anesthesiologists alike must be aware of the early clinical signs of this rare, yet potentially fatal, complication.

    The stomach is the preferred augmentation option for a contracted bladder in a patient with renal failure. A 49-year-old female presented with right solitary functioning kidney with tuberculous lower ureteric stricture and contracted bladder. Her creatinine was 2.8 mg%. By laparoscopic approach, right gastroepiploic artery based gastric flap was isolated using staplers and used for augmentation and ureteric replacement. At 6-month follow-up, her creatinine was 1.9 mg%, and bladder capacity was 250 ml. She had mild hematuria, which settled with proton pump inhibitors. Laparoscopic gastrocystoplasty is feasible and effective augmentation option in those with renal failure, giving the benefits of minimally invasive approach. PMID:28197034

    Ventriculoperitoneal (VP) shunts are the most common treatment modality for hydrocephalus. Distal catheter malfunction represents a surgical emergency and a significant cause of procedural morbidity. We report the case of a patient with acute abdominal pain following VP shunt insertion. On examination she had a tender, irreducible bulge at the abdominal laparotomy site. Exploratory laparoscopy of the abdomen yielded no abdominal wall abnormalities. At the same time, the distal catheter was noted to be absent. The abdominal bulge was incised along the laparotomy scar and clear cerebrospinal fluid was encountered. The incision was explored and the distal catheter was coiled and knotted within the preperitoneal space. The catheter was laparoscopically returned to the peritoneal cavity. This case exemplifies the utility of laparoscopy for VP shunt revision and we present a review of laparoscopic shunt revision.

    Gastric diverticula are rare and usually asymptomatic. This report, however, describes two examples of symptomatic gastric diverticula successfully treated by laparoscopic resection. Both patients were male and in their sixth decade of life. One patient was relatively healthy with no past medical history, whereas the other patient had chronic pain issues and at presentation was also undergoing evaluation for hyperaldosteronism. The patients presented with gastrointestinal symptoms, including nausea, emesis, abdominal pain, and change in bowel function. In both cases, a gastric diverticulum was identified by CT scan, and precise anatomic position was determined by upper endoscopy. After discussion with the treating teams, including a gastroenterologist and surgeon, surgical treatment and resection was elected. Successful laparoscopic removal was accomplished in both patients, and they were discharged home after tolerating liquid diets. Both patients reported resolution of their abdominal symptoms at follow-up. PMID:24680154

    Leiomyosarcoma is a rare malignant tumor originating from the smooth muscular tissue in any part of the organism. The only therapy is its complete removal. We describe herein the operative treatment of a retroperitoneal leiomyosarcoma with gasless laparoscopic complete removal. The procedure was successfully performed in a consenting woman with an abdominal mass. Gasless laparoscopic removal was performed with a mechanical retractor (Laparolift, Origin Medsystem Inc.), obviating the creation of the pneumoperitoneum and of the sealed environment. The technique is a simple, safe, and effective surgical method. Gasless technique guarantees a clear vision, makes possible continuous suction of smoke and fluids, and allows the use of conventional instruments and easy management of suturing. The present case has proved to be another abdominal procedure that can be carried out with all the advantages of gasless miniinvasive surgery.

    Nowzaradan, Y; Meador, J; Westmoreland, J

    1992-12-01

    After laparoscopic exploration of the common bile duct, or when a patient has acute cholecystitis, the cystic duct is sometimes edematous and too large to be ligated safely with an Endoclip. In such cases, ligation of the cystic duct with an Endoloop offers a solution to the problem. The standard technique for application of an Endoloop consists of dividing the cystic duct and then applying the Endoloop. This becomes more difficult if, after the cystic duct is divided, loss of traction on the common bile duct results in retraction of the divided cystic stump outside of the laparoscopic field of view. To avoid this difficulty, the authors apply an Endoloop with the grasping forceps on the cystic duct before the duct is divided so that it cannot retract from operative view and for this task developed an instrument that allows simultaneous introduction of both grasping forceps and the Endoloop through a single port.

    Splenic cysts are rare diseases that are diagnosed incidentally during imaging studies. When cysts are recognized, surgical treatment is recommended adapted to the particular case, depending on the size and location of the cyst and the age of the patient in order to avoid dangerous complications such as spleen rupture or cyst infection with abscess. We report 2patients with symptomatic splenic epidermoid cyst treated by laparoscopic cleavage. Laparoscopic cleavage is a surgical option for splenic cyst, with the goal of reducing postoperative complications while preserving splenic function.

    The purpose of this study was to evaluate the results of a laparoscopic transabdominal preperitoneal (TAPP) approach to inguinal hernia repair which dissected the entire inguinal floor and repaired the indirect, direct, and femoral areas in all patients without tension. In our series, 183 patients had 205 hernia repairs and were followed for more than 6 months. Of this group, 128 hernias were indirect, 55 direct, 22 pantaloon, 26 recurrent, and 22 bilateral. All 12 females and the first 11 males had a single-buttress repair with polypropylene mesh. The other 160 male patients had a double-buttress repair. With median follow-up of 12 months, ranging from 6 to 21 months, no recurrences were found. Patients returned to normal activity in an average of 1 week. Dissection and buttressing of the entire inguinal floor with mesh appeared to solve the problem of early recurrence first seen in laparoscopic herniorrhaphy.

    Mesenteric cysts are rare intraabdominal tumors, which cause plain symptoms. Despite the modern imaging techniques, the correct preoperative diagnosis is difficult. The optimal treatment is surgical excision of the cysts with open surgery, laparoscopy, or even retroperitoneoscopy. Surgical excision needs to be considered in case of complaints, growing cyst, or suspicion of malignancy. Indications for urgent surgery treatment are: bleeding, volvulus, torquation or ileus. Most frequently, mesenterial cysts are diagnosed during the operation of an unknown palpable abdominal cystic resistance. We present a case of a 32-year-old female patient with a jejunal mesenteric cyst, treated by laparoscopic resection. Postoperative period was uneventful, and after an early discharge the patient's recovery was free of symptoms. Histopathological examination revealed a benign cyst. We conclude that laparoscopic resection of abdominal cysts with unknown origin is a safe operation and can be recommended.

    Models of amphiphilic NO-donor antioxidants 24-26 were designed and synthesized. The products were obtained by linking a lipophilic tail (C(6), C(8), C(10)) with a polar head constituted by the 2,6-dimethoxyphenol antioxidant joined to the NO-donor 3-furoxancarboxamide substructure through a bridge containing a quaternary ammonium group. Compound 23, containing the shortest C(2)-alkyl chain, was also studied as a reference. The antioxidant properties (TBARS and LDL oxidation assays) and the vasodilator properties of the compounds were studied in vitro. The ability of these products to interact with phospholipid vesicles was also investigated by NMR techniques. The results indicate that both activities are modulated by the ability of the compounds to accumulate on phospholipid layers.

    Proponents of laparoscopic appendectomy emphasize the advantages of laparoscopic operation--decreased hospitalization, paralytic ileus, postoperative pain and wound complications, including infection. This study compared open laparoscopic appendectomy with laparoscopic appendectomy. To compare the two techniques, patients undergoing laparoscopic appendectomy at four hospitals were compared with patients undergoing open appendectomy during a six month period. Excluded were incidental appendectomies and patients with perforated appendicitis. An equal number of pediatric patients undergoing laparoscopic and open procedures were included in the analysis to avoid bias, because most of the laparoscopic appendectomies were performed in the adult patient population (age of more than 16 years). A University Medical Center, a Veterans Administration and two community hospitals were the settings. Patients undergoing laparoscopic appendectomy (n = 54) had an average age of 25.7 +/- 1.5 (range of six to 59 years). These patients were compared with 121 patients undergoing open appendectomy whose average age was 23.7 +/- 1.8 (range of three to 83 years). The race and gender distribution were similar in the two groups. Traditional open appendectomy was compared with a group of patients undergoing laparoscopic appendectomy. Variables evaluated were operating room time, number of patients who reported nausea, days until patient tolerated a regular diet, days of hospitalization, postoperative pain medication and wound infection rate. Results are expressed as the mean plus or minus standard error of the mean. Analysis of variance was used to compute continuous variables and Fischer's exact test was used for discrete variables. The laparoscopic approach was attempted in 61 patients and completed in 54 patients. Open appendectomy was performed upon 121 patients. Nineteen patients (18 who underwent open operation and one patient who underwent laparoscopic operation) were excluded from

    Purpose: We present the findings of 50 patients undergoing pure trans-umbilical laparo-endoscopic single-site surgery (LESS) living donor nephrectomy (LDN), between February 2010 and May 2014. Materials and Methods: Laparo-endoscopic single-site surgery LDN was performed through an umbilical incision. Different trocars were used, namely Gelpoint (Applied Mιdical, Rancho Santa Margarita, CA) SILS port (Covidien, Hamilton, Bermuda), R-port (Olympus Surgical, Orangeburg, NY) and standard trocars, inserted through the same skin incision but using separate fascial punctures. The standard laparoscopic technique was employed. The kidney was pre-entrapped in a retrieval bag and extracted trans-umbilically. Data were collected prospectively including questionnaires containing patient reported oral pain medication duration and time to recovery. Results: LESS LDN was successful in all patients. Mean warm ischemia time was 6.2 min (3–15), mean procedure time was 233.2 min (172–300), and hospitalization stay was 3.94 days (3–7) with a visual analogue pain score at discharge of 1.32 (0–3). No intraoperative complications occurred. The mean time of oral pain medication was 8.72 days (1–20) and final scar length was 4.06 cm (3–5). Each allograft was functional. Conclusion: Although challenging, trans-umbilical LESS LDN seems to be feasible and safe. Hence, LESS has the potential to improve cosmetic results and decrease morbidity. PMID:26229326

    OBJECTIVE: The authors determined whether there was an advantage to laparoscopic appendectomy when compared with open appendectomy. SUMMARY/BACKGROUND DATA: The advantages of laparoscopic appendectomy versus open appendectomy were questioned because the recovery from open appendectomy is brief. METHODS: From January 15, 1992 through January 15, 1993, 75 patients older than 9 years were entered into a study randomizing the choice of operation to either the open or the laparoscopic technique. Statistical comparisons were performed using the Wilcoxon test. RESULTS: Thirty-seven patients were assigned to the open appendectomy group and 38 patients were assigned to the laparoscopic appendectomy group. Two patients were converted intraoperatively from laparoscopic appendectomies to open procedures. Thirty-one patients (81%) in the open group had acute appendicitis, as did 32 patients (84%) in the laparoscopic group. Mean duration of surgery was 65 minutes for open appendectomy and 87 minutes for laparoscopic appendectomy (p < 0.001). There were no statistically significant differences in length of hospitalization, interval until resumption of a regular diet, or morbidity. Duration of both parenteral and oral analgesic use favored laparoscopic appendectomy (2.0 days versus 1.2 days, and 8.0 days versus 5.4 days, p < 0.05). All patients were instructed to return to full activities by 2 weeks postoperatively. This occurred at an average of 25 days for the open appendectomy group versus 14 days for the laparoscopic appendectomy group (p < 0.001). CONCLUSIONS: Patients who underwent laparoscopic appendectomies have a shorter duration of analgesic use and return to full activities sooner postoperatively when compared with patients who underwent open appendectomies. The authors consider laparoscopic appendectomy to be the procedure of choice in patients with acute appendicitis. PMID:8203983

    The aim of this study was to review our experience with laparoscopic sigmoid colectomy for diverticular disease. All patients presenting with acute or chronic diverticulitis, obstruction, abscess, or fistula were included. Symptomatic diverticular disease was the main surgical indication (95%). Between March 1992 and August 1999 170 consecutive patients underwent surgery. Of these, 21 patients (12%) had significant obesity, with body mass index (BMI) greater than 30. The average length of surgery was 141 +/- 36 min. In 163 patients (96%), the procedure was performed solely with the laparoscope. The nasogastric tube was removed on postoperative day 2 +/- 1.9, and oral feeding was started on postoperative day 3.4 +/- 2.1. The average length of hospital stay after surgery was 8.5 +/- 3.7 days. During the first postoperative month, there were no deaths. However, 11 patients (6.5%) had surgical complications: 5 anastomotic leaks (2.9%), 1 intraabdominal abscess (0.6%), and 3 wound infections (1.7%). There were four reinterventions (2.4%), with two diverting colostomies. Secondarily, 10 anastomotic stenoses (5.9%) were observed. Eight patients required a reintervention: seven anastomotic resections by open laparotomy and one terminal colostomy. Seven patients (4.1%) reported retrograde ejaculation, and one reported impotence. The feasibility of the laparoscopic approach to diverticular disease is established with a conversion rate of 4%, a low incidence of acute septic complications (5.3%), and a mortality rate of 0%. Therefore, laparoscopic sigmoid colectomy has become our procedure of choice in the treatment of diverticular disease.

This study included 14 senior general surgery residents (PGY 3-5) participating in a workshop in advanced laparoscopy. Four training tools were used in the course curriculum: the Fundamentals of Laparoscopic Surgery (FLS) black box suturing model, a synthetic Nissen fundoplication model, a virtual reality (VR) simulator suturing task, and a porcine jejuno-jejunostomy model. After the workshop, residents were asked to complete a questionnaire relating to their experience with laparoscopic surgery, and their opinions regarding the four training models. Model rank was analyzed with one-way ANOVA, and χ(2) analysis with Fisher's exact test was used to analyze model effectiveness. The majority of residents had strong experience in basic laparoscopic cases such as cholecystectomy and appendectomy; however, few participants had experience in advanced cases. As a group, the residents ranked the porcine model first (average 1.6, median 1), followed by the synthetic Nissen model (average 2.0, median 2), the FLS model (average 2.5, median 3), and the VR trainer (average 3.2, median 4). Finally, each resident was asked to rate the four models individually with respect to their educational value. Scores were on a Likert scale from 1 to 5. Nine of 11 (81.8%) residents rated the animal model as "extremely helpful" while only 3 of 14 (21.4%) participants rated the VR model as "extremely helpful" (p = 0.048). This study demonstrates that operative experience in advanced laparoscopy for senior residents is suboptimal. Residents learning this skill in a simulated environment prefer animal or video-trainers as teaching models rather than virtual reality. This has implications when designing a curriculum for advanced endoscopy.

    To demonstrate key steps in performing safe laparoscopic multiple myomectomy. Video focuses on stepwise description of all major steps of the surgical technique. Twenty-seven-year-old woman. Informed consent was taken from the subject, and the institutional review board approved this research. Laparoscopic multiple myomectomy with morcellation in bag. About one-third of women with fibroids present with symptoms severe enough to warrant treatment. We demonstrate a case of a 27-year-old woman with complaints of secondary infertility and menorrhagia. On examination the uterus was enlarged up to 24 weeks size. Ultrasonography mapping located 7 myomas ranging in size from of 3 to 10 cm and classified as International Federation of Gynecology and Obstetrics classes 2, 3, 4, 5, 6, and 7. Generally, laparotomy or laparoscopy and mini-laparotomy is performed for such cases of multiple myomas. However, the total laparoscopic approach can confer benefits if performed following safe steps and within good time. The following were the key steps of surgery: (1) Higher port position using Lee Huang point for primary port, (2) intermittent vasopressin use for each myomectomy, (3) cold technique of myomectomy, (4) myoma lace creation, (5) multiple layer suturing using double-ended barbed sutures, (6) myoma garland creation, and (7) morcellation in a stomach-shaped bag. The intermittent use of vasopressin is effective in reducing blood loss. Suturing using barbed sutures is less time consuming. Creating lace of myomas by passing a thread through each myoma, prevents losing them in the abdominal cavity and creating garland of myomas by tying two free ends of the lace helps in easier bagging. Morcellation in bag prevents dissemination of bits of myoma and visceral injury. These steps help in performing laparoscopic multiple myomectomy safely. However, this technique should be reserved for selected cases and should be performed by surgical teams with the required expertise and

    Scoliosis, which is often associated with neurological impairment in children, sometimes makes it difficult to perform laparoscopic procedures. This study assessed the impact of scoliosis on performing laparoscopic Nissen fundoplication. Medical records and radiographic examinations of patients who underwent laparoscopic Nissen fundoplication at a single institution from 2006 to 2015 were reviewed retrospectively. Patients' data on age at surgery, height, weight, duration of pneumoperitoneum, and amount of bleeding were collected. The Cobb angle was measured using X-rays, and the direction (right or left) of the scoliotic curve was recorded. The chest compression ratio was calculated using computed tomography axial images. Eighty-five patients were included and analyzed in this study, of which 89% were neurologically impaired. Median age, height, and weight were 120 months, 110 cm, and 17 kg, respectively. A positive correlation between age and the Cobb angle (ρ = 0.64) and a negative correlation between age and the chest compression ratio (ρ = -0.56) were observed. The right-curved scoliotic group showed significantly more bleeding than the nonscoliotic (<10°) group (P = .01; nonscoliotic, 0 mL; right curved, 7.5 mL; left curved, 0 mL). The severe scoliotic group (≥45°) showed more bleeding than the nonscoliotic group (P = .02). Neither the direction of the scoliotic curve nor scoliotic severity showed a significant difference in the duration of pneumoperitoneum. The older the patient, the more severe their scoliosis and chest compression were. Right-curved or severe scoliosis could be risk factors for intraoperative bleeding in laparoscopic Nissen fundoplication.

    Ingestion of foreign body is a serious problem commonly encountered in our clinical practice. Most of them pass spontaneously, whereas in others endoscopic or surgical intervention is required because of complications or non-passage from the gastrointestinal tract. We present here a case of teaspoon ingestion, which did not pass spontaneously. Laparoscopic retrieval of teaspoon was done from mid jejunum after enterotomy and the patient recovered uneventfully. Right intervention at the right time is of paramount importance. PMID:25336824

    Clostridial gas gangrene of the abdominal wall is rare, and it is usually associated with organ perforation, immunosuppression or gastrointestinal malignancies. In this paper we present a case of fulminant, endogenous gas gangrene in a 58-year old diabetic female with arterial hypertension and atherosclerosis, following uneventful laparoscopic cholecystectomy. She developed gas gangrene of the abdominal wall 12-hours after cholecystectomy and died 24-hours after the onset of the first symptoms, in spite of treatment.

    Intraoperative cholangiography (IC) in laparoscopic cholecystectomy is a controversial issue. According to traditional teaching, the purpose of cholangiography in gallbladder surgery is to discover previously undiscovered common bile duct stones. This examination was extremely important in the era before ERCP. IC enabled surgeons to find stones and remove them at the same operation. With progress in ERCP, the importance of intraoperative cholangiography has diminished. A stone missed during surgery can most often be dealt with by the less invasive ERCP and papillotomy. There has been a difference of opinion in the literature as to whether to perform cholangiography routinely during gallbladder operations or only in cases in which there is a specific indication, such as an enlarged common bile duct, a history of pancreatitis, or elevated enzymes. Routine operative cholangiography prolongs operative time and carries its own inherent risks, such as injury to the bile ducts. The likelihood of stones is not high and over-diagnosis of stones would result in unwarranted common bile duct exploration and the danger of complications from the procedure. The tendency today is towards a more selective approach. In this era of laparoscopic gallbladder surgery, the controversy has come to the fore again, and there is now an additional aspect. In laparoscopic gallbladder surgery there is greater significance to the "road map" provided by X-rays. We rely mainly on the visual sense and have forgone the tactile sense. Therefore, any added visual input in this operation helps avoid the danger of injuring the main bile ducts. It is our contention that the indications for operative cholangiography in laparoscopic cholecystectomy should again be broadened.

    Twenty-five ectopics pregnancies were treated successfully by laparoscopic approach from november 1990 to april 1992. The technics used were: salpingostomy, salpingectomy and taking out trophoblastic tissue exclusively. At the present time, two out of eight women who have wanted become pregnant, have delivered a healthy babies. We concluded that the ectopic pregnancy is efficiently managed by laparoscopy with advantages such as: minimal scar, short time in the hospital, quickly return to total activity, low costs, etc.

    AIM: To investigate the cooperative laparoscopic and endoscopic techniques used for the resection of upper gastrointestinal tumors. METHODS: A systematic research of the literature was performed in PubMed for English and French language articles about laparoscopic and endoscopic cooperative, combined, hybrid and rendezvous techniques. Only original studies using these techniques for the resection of early gastric cancer, benign tumors and gastrointestinal stromal tumors of the stomach and the duodenum were included. By excluding case series of less than 10 patients, 25 studies were identified. The study design, number of cases, tumor pathology size and location, the operative technique name, the endoscopy team and surgical team role, operative time, type of closure of visceral wall defect, blood loss, complications and length of hospital stay of these studies were evaluated. Additionally all cooperative techniques found were classified and are presented in a systematic approach. RESULTS: The studies identified were case series and retrospective cohort studies. A total of 706 patients were operated on with a cooperative technique. The tumors resected were only gastrointestinal stromal tumors (GIST) in 4 studies, GIST and various benign submucosal tumors in 22 studies, early gastric cancer (pT1a and pT1b) in 6 studies and early duodenal cancer in 1 study. There was important heterogeneity between the studies. The operative techniques identified were: laparoscopic assisted endoscopic resection, endoscopic assisted wedge resection, endoscopic assisted transgastric and intragastric surgery, laparoscopic endoscopic cooperative surgery (LECS), laparoscopic assisted endoscopic full thickness resection (LAEFR), clean non exposure technique and non-exposed endoscopic wall-inversion surgery (NEWS). Each technique is illustrated with the roles of the endoscopic and laparoscopic teams; the indications, characteristics and short term results are described. CONCLUSION: Along with

    Background Donor selection criteria for adult-to-adult living donor liver transplantation vary with the medical center of evaluation. Living donor evaluation utilizes considerable resources and the non-maturation of potential into actual donors may sometimes prove fatal for patients with end stage liver disease. On the contrary, a thorough donor evaluation process is mandatory to ensure safe outcomes in otherwise healthy donors. We aimed to study the reasons for non-maturation of potential right lobe liver donors at our transplant center. Methods A retrospective data analysis of all potential living liver donors evaluated at our center from 1998 to 2010 was done. Results Overall 324 donors were evaluated for 219 potential recipients and 171 (52.7%) donors were disqualified. Common reasons for donor non-maturation included: (1) Donor reluctance, 21% (2) >10% macro-vesicular steatosis, 16% (3) assisted donor withdrawal, 14% (4) inadequate remnant liver volume, 13% (5) psychosocial issues, 7% and thrombophilia, 7%. Ten donors (6%) were turned down due to anatomical variations (8 biliary and 2 arterial anomalies). Donors older than 50 years and those with BMI over 25 were less likely to be accepted for donation. Conclusions We conclude that donor reluctance, hepatic steatosis and assisted donor withdrawal are major reasons for non-maturation of potential into actual donors. Anatomical variations and underlying medical conditions were not a major cause of donor rejection. A system in practice to recognize these factors early in the course of donor evaluation to improve the efficiency of the selection process and ensure donor safety is proposed. PMID:23128999

    Background: The aim of this study was to compare peri-operative results of laparoscopic supracervical hysterectomy (LSH) with those of laparoscopic total hysterectomy (TLH). Methods: A retrospective cohort study was conducted at the Department of Gynecology at a teaching hospital. A group of 157 patients who underwent TLH was compared with a group of 157 patients who underwent LSH with or without bilateral salpingo-oophorectomy (BSO). Both groups had similar baseline characteristics and comparable surgical indications. Results: We reviewed our 7-year experience with laparoscopic hysterectomies performed at our department between October 2000 and November 2007. The similarities between patient characteristics were tested by using Wilcoxon Rank Sum Statistics. Patient and surgery characteristics as well as surgery outcomes were analyzed with descriptive statistics showing medians and 95% CIs. Women who underwent LSH had a shorter operation time compared with women in the TLH group (100 min vs. 110 min). Major complication rates were higher in the TLH group than in the LSH group (4.5% vs. 1.3%). Minor complication rates were 13.3% in the TLH group compared with 13.4% in the LSH group. Conclusions: Our data and experience provide specific information about the perioperative performance of LSH compared with TLH. In our experience, LSH proved to be a valid alternative to TLH in the absence of specific indications for TLH. Adequate counseling concerning the risk of cyclical bleeding and reoperation is mandatory. PMID:19793479

  20. Endoscopic and laparoscopic treatment of gastroesophageal reflux.

    Watson, David I; Immanuel, Arul

    2010-04-01

    Gastroesophageal reflux is extremely common in Western countries. For selected patients, there is an established role for the surgical treatment of reflux, and possibly an emerging role for endoscopic antireflux procedures. Randomized trials have compared medical versus surgical management, laparoscopic versus open surgery and partial versus total fundoplications. However, the evidence base for endoscopic procedures is limited to some small sham-controlled studies, and cohort studies with short-term follow-up. Laparoscopic fundoplication has been shown to be an effective antireflux operation. It facilitates quicker convalescence and is associated with fewer complications, but has a similar longer term outcome compared with open antireflux surgery. In most randomized trials, antireflux surgery achieves at least as good control of reflux as medical therapy, and these studies support a wider application of surgery for the treatment of moderate-to-severe reflux. Laparoscopic partial fundoplication is an effective surgical procedure with fewer side effects, and it may achieve high rates of patient satisfaction at late follow-up. Many of the early endoscopic antireflux procedures have failed to achieve effective reflux control, and they have been withdrawn from the market. Newer procedures have the potential to fashion a surgical fundoplication. However, at present there is insufficient evidence to establish the safety and efficacy of endoscopic procedures for the treatment of gastroesophageal reflux, and no endoscopic procedure has achieved equivalent reflux control to that achieved by surgical fundoplication.
