Leveling the learning curve for laparoscopic bariatric surgery

Multiple Complex Complications After Redo Bariatric Surgery (Infrequent Complication: Fistula Between the Splenic Artery and the Remnant of the Stomach): A Case Report

With the epidemic prevalence of obesity in today’s society, bariatric surgery has become very popular in treating severe obesity. Although the complications of this surgery have decreased with the advancement of medicine and post-treatment care, there are still complications that can lead to death if neglected. In this case report, we present a 44-year-old patient who underwent redo bariatric surgery. She was discharged from the hospital in good general condition but returned a few days later with a major complaint of abdominal pain and sudden bleeding from the upper gastrointestinal tract. After performing CT and endoscopy and considering the results, the patient underwent laparotomy, which showed a fistula between the splenic artery and the remnant of the stomach. After surgery and after the recovery period, the patient was discharged from the hospital. In this case report, we describe for the first time an uncommon and unique complication following redo bariatric surgery. We suggest that a fistula between the splenic artery and the remnant of the stomach should be considered in patients with abdominal pain and upper gastrointestinal bleeding who underwent redo bariatric surgery.

Learning Curves of Laparoscopic Roux-en-Y Gastric Bypass and Sleeve Gastrectomy in Bariatric Surgery: a Systematic Review and Introduction of a Standardization

BACKGROUND

The most commonly performed bariatric procedures are laparoscopic Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (LSG). Impact of learning curves on operative outcome has been well shown, but the necessary learning curves have not been clearly defined. This study provides a systematic review of the literature and proposes a standardization of phases of learning curves for RYGB and LSG.

METHODS

A systematic literature search was performed using PubMed, Web of Science, and CENTRAL databases. All studies specifying a number or range of approaches to characterize the learning curve for RYGB and LSG were selected.

RESULTS

A total of 28 publications related to learning curves for 27,770 performed bariatric surgeries were included. Parameters used to determine the learning curve were operative time, complications, conversions, length of stay, and blood loss. Learning curve range was 30-500 (RYGB) and 30-200 operations (LSG) according to different definitions and respective phases of learning curves. Learning phases described the number of procedures necessary to achieve predefined skill levels, such as competency, proficiency, and mastery.

CONCLUSIONS

Definitions of learning curves for bariatric surgery are heterogeneous. Introduction of the three skill phases competency, proficiency, and mastery is proposed to provide a standardized definition using multiple outcome variables to enable better comparison in the future. These levels are reached after 30-70, 70-150, and up to 500 RYGB, and after 30-50, 60-100, and 100-200 LSG. Training curricula, previous laparoscopic experience, and high procedure volume are hallmarks for successful outcomes during the learning curve.

Global Benchmark Values for Laparoscopic Roux-en-Y-Gastric Bypass: a Potential New Indicator of the Surgical Learning Curve

Background

Laparoscopic Roux-en-Y gastric bypass (LRYGB) is a technically demanding procedure. The learning curve of LRYGB is challenging and potentially associated with increased morbidity. This study evaluates whether a general laparoscopic surgeon can be safely trained in performing LRYGB in a peripheral setting, by comparing perioperative outcomes to global benchmarks and to those of a senior surgeon.

Methods

All consecutive patients undergoing primary LRYGB between January 2014 and December 2017 were operated on by a senior (A) or a trainee (B) bariatric surgeon and were prospectively included. The main outcome of interest was all-cause morbidity at 90 days. Perioperative outcomes were compared with global benchmarks pooled from 19 international high-volume centers and between surgeons A and B for their first and last 30 procedures.

Results

The 213 included patients had a mean all-cause morbidity rate at 90 days of 8% (17/213). 95.3% (203/213) of the patients were uneventfully discharged after surgery. Perioperative outcomes of surgeon B were all within the global benchmark cutoffs. Mean operative time for the first 30 procedures was significantly shorter for surgeon A compared with surgeon B, with 108.6 min (± 21.7) and 135.1 min (± 28.1) respectively and decreased significantly for the last 30 procedures to 95 min (± 33.7) and 88.8 min (± 26.9) for surgeons A and B respectively.

Conclusion

Training of a new bariatric surgeon did not increase morbidity and operative time improved for both surgeons. Perioperative outcomes within global benchmarks suggest that it may be safe to teach bariatric surgery in peripheral setting.

Surgical resident training program to perform laparoscopic bariatric procedures: Are safety and postoperative outcomes compromised?

INTRODUCTION

Laparoscopic bariatric procedures such as laparoscopic Roux-en-Y gastric bypass (LRYGB) are technically demanding and require a long learning curve. Little is known about whether surgical resident (SR) training programs to perform these procedures are safe and feasible. This study aims to evaluate the results of our SR training program to perform LRYGB.

METHODS

We designed a retrospective study including patients with LRYGB between January 2014 and December 2018, comparing SR results to experienced bariatric surgeons (EBS). In our country, SR have a five-year surgical formative period, and in the fourth year they are trained for 6 months in our bariatric surgery unit, from January to June. In the beginning, they perform different steps of this procedure, to finally complete an LRYGB. We collected demographic data, comorbidities, intraoperative outcomes, and postoperative complications and outcomes after a one-year follow-up.

RESULTS

Two hundred and eight patients were eligible for inclusion: 67 in group I (SR), and 141 in group II (EBS). Both groups were comparable. There was no statistically significant difference in operating time (166.45min in group I vs. 156.69min in group II; P=0.156). Conversion to open surgery, hospital stay, postoperative complications, and short-term outcomes had no significant differences between the two groups. There was no mortality registered during this period.

CONCLUSION

Implementation of LRYGB stepwise learning as part of an SR training program is safe, and results are comparable to EBS, without loss of efficiency. Therefore, it is feasible to train SR in bariatric surgery under EBS supervision.

Systematic review of operative outcomes of robotic surgical procedures performed with endoscopic linear staplers or robotic staplers

A comprehensive review of operative outcomes of robotic surgical procedures performed with the da Vinci robotic system using either endoscopic linear staplers (ELS) or robotic staplers is not available in the published literature. We conducted a literature search to identify publications of robotic surgical procedures in all specialties performed with either ELS or robotic staplers. Twenty-nine manuscripts and six abstracts with relevant information on operative outcomes published from January 2011 to September 2017 were identified. Given the relatively recent market release of robotic staplers in 2014, comparative perioperative clinical outcomes data on the performance of ELS vs. robotic staplers in robotic surgery is very sparse in the published literature. Only three comparative studies of surgeries with the da Vinci robotic system plus ELS vs. da Vinci plus robotic staplers were identified; two in robotic colorectal surgery and the other in robotic gastric bypass surgery. These comparative studies illustrate some nuances in device design and usability, which may impact outcomes and cost, and therefore may be important to consider when selecting the appropriate stapling technologies/technique for different robotic surgeries. Comparative perioperative data on the use of ELS vs. robotic staplers in robotic surgery is scarce (three studies), and current literature identifies both types of devices as safe and effective. Given the longer clinical history of ELS and its relatively more robust evidence base, there may be trade-offs to consider before switching to robotic staplers in certain robotic procedures. However, this literature review may serve as an initial reference for future research.

The safety and efficiency of a fast-track protocol for sleeve gastrectomy: a team approach

BACKGROUND

Increasing numbers of morbid obese patients has led to increased numbers of bariatric procedures. Fast-track protocols are being developed to enhance the available resources, while maintaining a safe procedure. Reported results on safety merely apply to a mixed bariatric population. The objective was to evaluate safety and efficiency of the fast-track principles in patients undergoing sleeve gastrectomy.

METHODS

Retrospective observational study including patients undergoing primary sleeve gastrectomy at the Obesity Centre of the Catharina Hospital Eindhoven, the Netherlands. Conventional perioperative care (CC) (2008-2011) versus a fast-track protocol (FT) (2011-2013), using short-acting anesthetic agents, a multi-modal pain protocol to reduce opioids, and early mobilization. The main parameters for safety were intraoperative, early and late postoperative complications. Procedure time and hospital stay were used to evaluate efficiency.

RESULTS

This study included 805 patients, 494 patients were subjected to the conventional care and 318 patients to fast-track protocol. A reduction of median operation time from 60 (CC) to 40 minutes (FT) (P<0.001) and a reduction in median length of hospital stay from three to two days (P=0.001), with a significant reduction in early postoperative complications (9.9% [CC] vs. 5% [FT], P=0.016) was achieved. The amount of late complications was comparable for both groups (5.1% [CC] vs. 4.4% [FT] [P=0.738]).

CONCLUSIONS

Implementation of a fast-track protocol for sleeve gastrectomy is safe and efficient. It effectively reduces operation time and length of hospital stay, while improving postoperative outcome. This pleads for standard implementation of the fast-track protocol in sleeve gastrectomy.

A Narrative of Intraoperative Staple Line Leaks and Bleeds During Bariatric Surgery

The primary objective of this review was to assess the incidence of intraoperative staple line leaks and bleeds during laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB). A literature search of MEDLINE®, EMBASE™, and Biosis from January 2010 to November 2014, plus secondary citations extending to 2008, identified 16 relevant articles. For LSG, the incidence of intraoperative leaks and bleeds was as high as 3.93 and 4.07 %, respectively. For LRYGB, leaks occurred in up to 8.26 % and bleeds in 3.45 % of cases. Stapler misfire was commonly cited as a cause. Widespread, precautionary use of staple line reinforcement (SLR), lack of standardized testing, and underreporting suggest the incidence may be underestimated. Published studies were insufficient to address the economic impact of bleeds and leaks or interventions, but development of improved stapler designs that obviate the need for SLR may reduce costs and improve outcomes.

[Outcomes, controversies and gastric volume after laparoscopic sleeve gastrectomy in the treatment of obesity]

BACKGROUND

Laparoscopic sleeve gastrectomy is a surgical procedure for the treatment of morbid obesity. However, there are still controversies regarding its efficiency in terms of weight reduction and incidence of complications. In this prospective study, the experience is presented of a referral centre for the treatment of morbid obesity with laparoscopic sleeve gastrectomy.

MATERIAL AND METHODS

A prospective study on 73 patients subjected to laparoscopic sleeve gastrectomy from February 2009 to September 2013. Patients were followed-up for a period of 12 months, evaluating the development of complications, reduction of gastric volume, and the weight loss associated with the surgery, as well as their impact on the improvement of comorbidities present at beginning of the study.

RESULTS

There was a statistically a significantly reduction between the preoperative body mass index (BMI) and the BMI at 12 months after laparoscopic sleeve gastrectomy (p < 0.001), despite there being an increase in the gastric volume during follow-up, measured at one month and 12 months after surgery (p < 0.001). Five patients (6.85%) had complications, with none of them serious and with no deaths in the whole series.

CONCLUSIONS

Laparoscopic sleeve gastrectomy is a safe and effective technique for the treatment of morbid obesity. Its use is associated with a significant reduction in the presence of comorbidities associated with obesity. Multicentre studies with a longer period of monitoring are required to confirm the efficacy and safety of this surgical technique.

Early Outcomes of Roux-en-Y Gastric Bypass in a Publically Funded Obesity Program

Background. There is limited literature assessing the outcomes of bariatric surgery in a publically funded, North American, multidisciplinary bariatric program. Our objective was to assess outcomes of roux-en-Y gastric bypass (RYGB) in a publically funded bariatric program through a retrospective review of patient records. Methods. 293 patients spent a median of 13 months attending a multidisciplinary obesity clinic prior to undergoing laparoscopic RYGB surgery. The hospital was a Canadian, publically funded, level 2 trauma center with university teaching services. Results. 79% of the patients were female and the average BMI at first visit to clinic was 55.3 kg/m2. The average decrease in BMI was 19.2 ± 0.9 kg/m(2). This was an average absolute weight loss of 56.1 kg or 35.5% of initial weight. The average excess weight loss was 63.4 ± 20.4%. Improvement or resolution of obesity related comorbidities occurred in 65.9% of type 2 diabetics and in 50% of hypertensive patients. Conclusion. Despite this being an unconventional setting of a publically funded program in a large Canadian teaching hospital, early outcomes following RYGB were appropriate in severely obese patients. Ongoing work will identify areas of improvement for enhanced efficiencies within this system.

Overcoming the learning curve of laparoscopic Roux-en-Y gastric bypass: a 12-year experience

BACKGROUND

Surgical treatment of morbid obesity with laparoscopic Roux-en-Y gastric bypass (LRYGB) is technically challenging and involves high-risk patients. In this study, the short-term outcome of LRYGB in a large population of patients has been evaluated, and morbimortality before and after overcoming the learning curve has been assessed. The objective of this study was to establish the learning curve for laparoscopic Roux-en-Y gastric bypass.

METHODS

This retrospective study involved 2281 patients submitted to LRYGB at São José do Avaí Hospital between August 1999 and December 2011. The parameters analyzed were operating time, rates of short-term postoperative complications, mortality, and conversion.

RESULTS

The study population was predominantly female (71.3%) and presented a mean age of 37.5 years and mean body mass index (BMI) of 45.15 kg/m(2). The average time in surgery was 119 minutes, and average hospital stay was 4.3 days. The incidence of postoperative complications (hemorrhage, fistula, and bowel obstruction) was 1.75%. The relative risk of complications diminished in line with the increased experience of the surgical team and tended to stabilize at<2.5% after the first 500 procedures. The mortality rate was .43%, and the main causes of death were pulmonary embolism and leaks (.14% each). The conversion rate was .17%.

CONCLUSION

Operating time and risks of adverse outcome were significantly reduced after a long learning curve of 500 consecutive procedures. The number of surgeries performed and the standardization of the laparoscopic technique used were the main factors contributing to the low rates of postoperative complications, mortality, and conversion.

Training programs influence in the learning curve of laparoscopic gastric bypass for morbid obesity: a systematic review

The makeup of a new surgical bariatric team may be associated with a higher number of postoperative complications due to the learning curve. The aim of this study was to evaluate the outcomes during the learning curve of laparoscopic gastric bypass (LGBP) depending on surgeons' training. A systematic approach was used to review studies from the Pubmed, Embase (Ovid), Cancer Lit, Biomes Central via Scirus, Current Contens (ISI), and Web of Science (SCI) databases. Two reviewers independently screened all titles/abstracts and included/excluded studies based on full copies of manuscripts. The outcomes included were: specific training of the surgeon, postoperative complications (leaks, occlusion, hemorrhage, pneumonia, etc.), mortality, and surgical technique. One reviewer put data onto an Excel spreadsheet. Statistical analysis was performed with weighted linear regression. We identified 448 citations, of which 120 abstract and 50 full-text publications were reviewed. Fourteen papers were selected. Data from 1,848 patients were included. Eighteen different surgeons were analyzed during their learning curve (including the first author of this study). Surgeons were divided into two groups: (1) without formal laparoscopic bariatric training (13 surgeons) and (2) with formal laparoscopic bariatric training (five surgeons). Postoperative complications were more frequent in group 1: 18.1% (± 7.6) vs. 7.7% (± 1.96, p = 0.046); also, mortality was more frequent in group 1: 0.57% (± 0.87) vs. 0% (p = 0.05). An appropriated training in laparoscopic bariatric surgery contributes to a significant reduction in postoperative complications and mortality during the learning curve of LGBP.

High-volume bariatric surgery in a single center: safety, quality, cost-efficacy and teaching aspects in 2,000 consecutive cases

BACKGROUND

Obesity surgery is the most effective treatment for morbid obesity and the fastest growing area in surgery. Laparoscopic Roux-en-Y gastric bypass (LRYGB) is the gold standard procedure in many countries. Optimization of the treatment process is important in order to keep the morbidity rate down and cost of treatment as low as possible.

METHODS

In September 2005, we established a bariatric surgery program. Until December 2010, 2,000 patients underwent LRYGB. Clinical pathways were established, with focus on safety, fast-track methodology and training of surgeons. Time recordings from all parts of the treatment, as well as clinical outcome, were prospectively registered.

RESULTS

Time consumption for the total procedure in the operating theater was reduced from 102 to 54 min (P < 0.001). With only 11 min turnover between patients, the total time for one patient has been reduced to 65 min, enabling us to perform six operations in a single operating theater during ordinary daytime. Early complication rate was 2.8%, and mean hospital stay was 2.3 days. We were able to double the patients treated in 2010 compared to 2007 with only 10% increase in staff. Three surgeons were trained during the period into fully qualified senior bariatric surgeons.

CONCLUSIONS

Multimodal evidence-based care within the fast-track methodology and routine time recordings was successful in order to increase the production volumes and reduce costs, without compromising the safety or quality for the patients. This kind of approach may be transferred to other types of standardized surgery.

Simulation-based training and learning curves in laparoscopic Roux-en-Y gastric bypass

BACKGROUND

Ex vivo simulation-based technical skills training has been shown to improve operating room performance and shorten learning curves for basic laparoscopic procedures. The application of such training for laparoscopic Roux-en-Y gastric bypass (LRYGBP) has not been reviewed.

METHODS

Relevant studies were identified by one author from a search of MEDLINE and Embase databases from 1 January 1994 to 30 November 2010. Studies examining the learning curves and ex vivo training methods for LRYGBP were included; all other types of bariatric operations were excluded. A manual search of the references was also performed to identify additional potentially relevant papers.

RESULTS

Twelve studies (5 prospective and 7 retrospective case series) were selected for review. The learning curve for LRYGBP was reported to be 50-100 procedures. Bench-top laparoscopic jejunojejunostomy, anaesthetized animals and Thiel human cadavers made up the bulk of the reported models for ex vivo training. Most studies were of relatively poor quality. An evidence-based ex vivo training curriculum for LRYGBP is currently lacking.

CONCLUSION

Better quality studies are needed to define the learning curve for LRYGBP. Future studies should focus on the design and validation of training models, and a comprehensive curriculum for training and assessment of cognitive, technical and non-technical components of competency for laparoscopic bariatric surgery.

A new and standardized approach for trocar placement in laparoscopic Roux-en-Y gastric bypass

INTRODUCTION

Super-morbidly obese patients undergoing laparoscopic Roux-en-Y gastric bypass (LRYGB) present unique technical challenges. In our experience the ease of the operation and the operative time seem to be more dependent on body habitus than body mass index (BMI). We hypothesized that the distance between the xyphoid process and the umbilicus (the XU distance) correlated with surgical difficulty and described an original modification of trocar placement based on this measurement to improve the ease of the operation.

METHODS

Seven hundred and seventy-four patients underwent LRYGB, and the XU distance was measured in a subset of 38 patients midway through the experience. The need for additional trocars was assessed intraoperatively and the relationship between the XU distance and the need for extra trocars was subsequently analyzed. A standardized approach for trocar placement was implemented in the second half of our series. The operative time was compared between the standardized and nonstandardized groups.

RESULTS

Fifty percent of the patients required a five-trocar technique. Median XU distance in this group was 21.4 cm (range 17-25 cm). In the remaining 19 patients additional trocars were added; median XU distance was 27.3 cm (range 24-33 cm). From the 774 patients included in the study period, the operative time for the first 322 patients who were completed with a nonstandardized trocar approach was significantly longer than the subsequent 452 cases in which the standardized trocar approach was used (210 versus 173 min, p < 0.001).

CONCLUSIONS

We define XU distance as the key element in determining the choice of trocar placement. When XU distance is less then 25 cm, the basic approach should be used and if it is greater than 25 cm, the advanced trocar approach is recommended. This standardized technique leads to decreased operative time and improved ease of operation.

Can an Advanced Laparoscopic Fellowship Program be Established Without Compromising the Center's Outcomes?

The objective of this study is to assess the impact of establishing a fellowship training program on a center's laparoscopic gastric bypass (LGB) outcomes. The authors compare their prefellowship and postfellowship LGB outcomes by means of retrospective review of a prospectively maintained bariatric database. Theirs is an academic community hospital that instituted a minimally invasive bariatric program in 2001 and an advanced laparoscopic fellowship with emphasis in laparoscopic gastric bypass in 2003. Participants were patients undergoing LGB from the inception of the program. All prefellowship LGBs were performed and assisted by the same surgeon and assistant. Results show that prefellowship and postfellowship patient demographics were similar. The mean length of stay was 2.17 and 2.35 days, respectively. The percentage excess weight loss was 72% and 72%, respectively (p = 0.990). Major or minor complication rates were not significantly different between groups. The prefellowship operative time was 123 ± 22 minutes, compared with 154 ± 28 minutes postfellowship ( P = .001). In conclusion, a training-related increase in operative time was the only difference in the 2 groups. An advanced laparoscopic fellowship training program with emphasis in LGB can be safely established without compromising the center's LGB outcomes.

Establishing laparoscopic Roux-en-Y gastric bypass: perioperative outcome and characteristics of the learning curve

BACKGROUND

Bariatric surgery was established at several Norwegian hospitals in 2004. This study evaluates the perioperative outcome and the learning curves for two surgeons while introducing laparoscopic Roux-en-Y gastric bypass (LRYGB).

METHODS

Morbidly obese patients undergoing primary LRYGB were included. Lengths of surgery and postoperative hospital stay, and 30-day rates of morbidity, reoperations, and readmissions were set as indicators of the learning curve. Learning effects were evaluated by graphical analyses and comparing the first and last 40 procedures for both surgeons.

RESULTS

The 292 included patients had a mean age of 40.0 +/- 9.5 years and a mean body mass index (BMI) of 46.7 +/- 5.3 kg/m(2). The mean length of surgery was 101 +/- 55 min. Complications occurred in 43 patients (14.7%), with no conversions to open surgery in the primary procedure and no mortality. Reoperations were performed in 14 patients (4.8%), of which five patients required open surgery. The median length of stay was 3 days (range 1-77), and 19 patients (6.5%) were readmitted. High patient age, but not high BMI, was associated with an increased risk of complication. For both surgeons, lengths of surgery and hospital stay were significantly reduced (p < 0.001), leveling out after 100 procedures. Reductions in the rates of morbidity, reoperations and readmissions were not found.

CONCLUSION

LRYGB was introduced with an acceptable morbidity rate and no mortality. Only the length of surgery and postoperative hospital stay were suitable indicators of a learning curve, which comprised about 100 cases.

Advanced laparoscopic skills decrease the learning curve for laparoscopic Roux-en-Y gastric bypass

BACKGROUND

The reported learning curve for laparoscopic Roux-en-Y gastric bypass (LRYGB) is 20-100 cases. Our aim was to investigate whether advanced laparoscopic skills could decrease the learning curve for LRYGB with regard to major morbidity.

METHODS

The senior author performed all operations in this series. His training included a laparoscopic fellowship without bariatric surgery, six years in surgical practice focusing on upper abdominal laparoscopic surgery, two courses on bariatric surgery at national meetings, one week of observing a bariatric program, and two mentored LRGBY cases. A comprehensive obesity program was put in place before the program began. Data were collected prospectively and reviewed at the series' end. Results are presented as mean +/- standard deviation and standard statistical analysis was applied.

RESULTS

Between December 2003 and February 2005, 107 LRYGB operations were performed. Mean operative time decreased significantly with experience (p < 0.0001) and was 154 +/- 29, 132 +/- 40, 127 +/- 29, and 114 +/- 30 min by quartile. Mean length of stay was 2.9 +/- 1.6 days. Mean excess weight loss was 45.3% (n = 41) at six months. There were no conversions to an open procedure, no anastomotic leaks, no pulmonary embolisms, and no bowel obstructions. The five major complications (3 in the first 50 and 2 in the last 57 cases, p = NS) were two cases of biliopancreatic limb obstruction, two cases of significant gastrointestinal bleeding from anastomotic ulcer, and one case of gastric volvulus of the remnant stomach.

CONCLUSIONS

A bariatric fellowship and/or extended mentoring are not required to safely initiate a bariatric program for surgeons with advanced laparoscopic skills. Operative time decreases significantly with experience, but morbidity and mortality remain low even early in the learning curve. A comprehensive obesity program seems necessary for success.

Robotic prostatectomy: the first UK experience

BACKGROUND

We describe a teamwork approach to setting up the UK's first clinical programme for robotically assisted laparoscopic radical prostatectomy.

METHODS

On 22 November 2004 the Imperial Robotic Urological Surgery Group performed their first robotically assisted prostatectomy. Robotically assisted prostatectomy lends itself to division into eight definable stages. A team of four consultant urological surgeons utilized a structured rotating system, using these stages, for time at the console and tableside assisting. Fluidity of surgery was maintained by a surgeon acting as the tableside assistant for the stage prior to moving to the console. Data was collected prospectively for the first 50 cases and parameters associated with the learning curve compared to other reported series.

RESULTS

Median operative time of 369.5 mins, median blood loss of 700 ml, with 12% of patients requiring a blood transfusion. Four patients required conversion to an open procedure; one resulting from equipment failure and three due to failure of progression. Four patients had an anastomotic leak with resulting ileus and two patients sustained rectal injuries, which were repaired intraoperatively using the robot. Median hospital stay was 4 days with a 22% positive surgical margin rate.

CONCLUSION

Parameters indicative of the learning curve are comparable to existing published initial series of other robotic centres. The use of teamwork has enabled us to provide safe and time-efficient training for four surgeons simultaneously. The structured approach used in this setting demonstrates that urological surgeons of varying laparoscopic experience can acquire the skills necessary to competently perform laparoscopic radical prostatectomy.
