Abstract
BACKGROUND The adoption of new surgical technologies is inevitably accompanied by a learning curve. With the increasing adoption of robotic techniques in benign foregut surgery, it is imperative to define optimal learning pathways, to ensure a clinically safe introduction of such a technique. The aim of this study was to assess the learning curve for robotic hiatal hernia repair with a pre-defined adoption process and proctoring. METHODS The learning curve was assessed in four surgeons in a high-volume tertiary referral centre, performing over a 100 hiatal hernia repairs annually. The robotic adoption process included simulation-based training and a multi-day wet lab-based course, followed by robotic operations proctored by robotic upper GI experts. CUSUM analysis was performed to assess changes in operating time in sequential cases. RESULTS Each surgeon (A, B, C and D) performed between 22 and 32 cases, including a total of 109 patients. Overall, 40 cases were identified as 'complex' (36.7%), including 16 revisional cases (16/109, 14.7%). With CUSUM analysis inflection points for operating time were seen after 7 (surgeon B) to 15 cases (surgeon B). CONCLUSION The learning curve for robotic laparoscopic fundoplication may be as little as 7-15 cases in the setting of a clearly organized learning pathway with proctoring. By integrating these organized learning pathways learning curves may be shortened, ensuring patient safety, preventing detrimental outcomes due to longer learning curves, and accelerating adoption and integration of novel surgical techniques.

Abstract
PURPOSE The recurrence rate of gastroesophageal reflux disease (GERD) after fundoplication has been reported to be 7-25%. We investigated the risk factors for recurrence of GERD after Thal fundoplication (TF) in our department with the aim of further reducing the recurrence rate of GERD. METHODS We retrospectively analyzed 276 patients who underwent TF for GERD at our hospital between 2000 and 2019. Retrospectively considered variables were obtained from the medical records of patients. The variables included patient characteristics, GERD severity, surgery-related factors and postoperative course. RESULTS The postoperative GERD recurrence rate was 5.8%. In the univariate analysis, the presence of convulsive seizures (12/4 vs. 110/150, p = 0.046) and the absence of a tracheostomy (0/16 vs. 53/207, p = 0.048) at the time of TF were significantly associated with recurrence. In the multivariate analysis, the presence of convulsive seizures at the time of TF was the only factor significantly associated with recurrence. CONCLUSION The presence of convulsive seizures and the absence of a tracheostomy at the time of TF were significantly associated with GERD recurrence after TF. Active control of seizures and consideration of surgical indications, including assessment of respiratory status, are important in preventing the recurrence of GERD after TF.

Abstract
OBJECTIVE To evaluate the economic and clinical feasibility of introducing rigid endoscopy and laparoscopy to a small animal general practice. DESIGN Prospective study. SAMPLE A single 2-veterinarian small animal practice in southern California. PROCEDURES In early 2012, endoscopic equipment was purchased, and both veterinarians in the practice undertook training in rigid endoscopic and laparoscopic procedures. Subsequently, information for client-owned animals that underwent endoscopic and laparoscopic procedures during a 12-month period (2012 to 2013) was collected. Cost of equipment and training, revenue generated, specific procedures performed, surgery time, complications, and client satisfaction were evaluated. RESULTS 78 endoscopic procedures were performed in 73 patients, including 71 dogs, 1 cat, and 1 rabbit. Cost of endoscopic and laparoscopic equipment and training in the first year was $14,809.71; most equipment was financed through a 5-year lease at a total cost of $57,507.70 ($ 10,675.20/y). Total revenue generated in the first year was $50,423.63. The most common procedures performed were ovariectomy (OVE; n = 49), prophylactic gastropexy (6), and video otoscopy (12). Mean ± SD surgery times for OVE (n = 44) and for OVE with gastropexy (5) were 63.7 ± 19.7 minutes and 73.0 ± 33.5 minutes; respectively. Twelve of 54 patients undergoing laparoscopic procedures experienced minor intraoperative complications. Conversion to laparotomy was not required in any patient. There were no major complications. All 49 clients available for follow-up were satisfied. CONCLUSIONS AND CLINICAL RELEVANCE With appropriate training and equipment, incorporation of basic rigid endoscopy and laparoscopy may be feasible in small animal general practice. However, results of the present study are not applicable to all veterinarians and practice settings, and patient safety considerations should always be paramount.

Does the cost of robotic cholecystectomy translate to a financial burden? Surg Endosc 2014; 29:2115-20.

Abstract
INTRODUCTION Robotic application to cholecystectomy has dramatically increased, though its impact on cost of care and reimbursement has not been elucidated. We undertook this study to evaluate and compare cost of care and reimbursement with robotic versus laparoscopic cholecystectomy. METHODS AND PROCEDURES The charges and reimbursement of all robotic and laparoscopic cholecystectomies at one hospital undertaken from June 2012 to June 2013 were determined. Operative duration is defined as time into and time out of the operating room. Data are presented as median data. Comparisons were undertaken using the Mann-Whitney U-test with significance accepted at p ≤ 0.05. RESULTS Robotic cholecystectomy took longer (47 min longer) and had greater charges ($8,182.57 greater) than laparoscopic cholecystectomy (p < 0.05 for each). However, revenue, earnings before depreciation, interest, and taxes (EBDIT), and Net Income were not impacted by approach. CONCLUSIONS Relative to laparoscopic cholecystectomy, robotic cholecystectomy takes longer and has greater charges. Revenue, EBDIT, and Net Income are similar after either approach; this indicates that costs with either approach are similar. Notably, this is possible because much of hospital-based costs are determined by cost allocation and not cost accounting. Thus, the cost of longer operations and costs inherent to the robotic approach for cholecystectomy do not translate to a perceived financial burden.

Abstract
Transoral incisionless fundoplication (TIF) was U.S. Food and Drug Administration-approved in 2007 to treat gastroesophageal reflux disease (GERD), but comparative data are lacking. This study was undertaken to compare outcomes for patients with GERD undergoing TIF versus laparoscopic Nissen or Toupet fundoplications. We undertook a case-controlled study of three cohorts of 20 patients undergoing TIF or laparoscopic Nissen or Toupet fundoplications from 2010 to 2013 controlling for age, body mass index, and preoperative DeMeester scores. All patients were pro-spectively followed. Median data are reported. Patients undergoing TIF had significantly shorter operative times (in minutes: 71 vs 119 and 85, respectively, P < 0.001) and length of stay (in days: 1, 2, and 1, respectively, P < 0.001). No matter the approach, patients reported dramatic and similar reduction in symptom frequency and severity (e.g., heartburn 8 to 0, P < 0.05). At follow-up, 83 per cent of patients after TIF, 80 per cent after Nissen, or 92 per cent after Toupet fundoplications had symptoms less than once per month ( P = 0.12). TIF leads to dramatic symptom resolution, similar when compared with Nissen or Toupet fundoplications. TIF promotes shorter operative times and lengths of stay. Patient satisfaction and effective palliation of symptoms show that TIF is safe and efficacious in comparison to Nissen and Toupet fundoplications and support its continued application and evaluation.

Abstract
The learning curve for laparoendoscopic single-site (LESS) surgery was found to be definable, short, and safe. Background and Objectives: This study of laparoendoscopic single-site (LESS) fundoplication for gastroesophageal reflux disease was undertaken to determine the “learning curve” for implementing LESS fundoplication. Methods: One hundred patients, 38% men, with a median age of 61 years and median body mass index of 26 kg/m2, underwent LESS fundoplications. The operative times, placement of additional trocars, conversions to “open” operations, and complications were compared among patient quartiles to establish a learning curve. Median data are reported. Results: The median operative times and complications did not differ among 25-patient cohorts. Additional trocars were placed in 27% of patients, 67% of whom were in the first 25-patient cohort. Patients undergoing LESS fundoplication had a dramatic relief in the frequency and severity of all symptoms of reflux across all cohorts equally (P < .05), particularly for heartburn and regurgitation, without causing dysphagia. Conclusion: LESS fundoplication ameliorates symptoms of gastroesophageal reflux disease without apparent scarring. Notably, few operations required additional trocars after the first 25-patient cohort. Patient selection became more inclusive (eg, more “redo” fundoplications) with increasing experience, whereas operative times and complications remained relatively unchanged. The learning curve of LESS fundoplication is definable, short, and safe. We believe that patients will seek LESS fundoplication because of the efficacy and superior cosmetic outcomes; surgeons will need to meet this demand.

Abstract
BACKGROUND Gastroesophageal reflux is the gastrointestinal tract disease most frequently find nowadays. The Nissen-Rossetti fundoplication is widely used for the surgical treatment, and intrathoracic migration of the valve is the most frequent complication. AIM To assess the incidence of the fundoplication and its risk factors. METHODS Were analyzed retrospectively medical records of 207 patients undergoing laparoscopic fundoplication by the Nissen-Rossetti technique for the treatment of reflux disease. The variables analyzed were: sex, age, esophagitis grade, size of the herniation, enlargement of the cardia and esophageal shortening. For quantitative variables, was considered the Student's t test. For the nominal, was considered the chi-square or Fisher's exact test. P values <0.05 were considered statistically significant. RESULTS Of the total, 135 were women (65.22%) and 72 men (34.78%) with mean age of 47.43 years. The size of the hernia varied between 2 and 6 cm. Two hundred patients had esophagitis (96.62%) and 113 (56.50%) grade I, 75 grade II (37.50%) and 12 grade III or IV (6%). Enlargement of the cardia and Barrett's esophagus were seen in 153 (73.91%) and 13 (6.28%) cases, respectively. One patient had esophageal shortening. Among women, 33 (24.4%) showed migration and among men, only six (8.3%) (p = 0.005). The average age of patients with and without migration was 54.03 and 45.89 years, respectively (p = 0.001). CONCLUSION The incidence of the fundoplication migration was 18.8%. The gender (female) and higher age influence the probability of migration. The degree of esophagitis, size of hernia and enlargement of the cardia were not risk factors for intrathoracic migration of the fundoplication.

Abstract
BACKGROUND AND AIMS Good long term result after Nissen fundoplication is achieved in most of the patients in specialized centres. Still failure occurs in some cases and reoperation after failed conservative treatment is done in 3-6% of the cases. Reoperation is more dangerous and results worse than after primary fundoplication. Therefore we wanted to analyze factors related to failure of Nissen fundoplication with special emphasis on utilization of crural closure, anchor-ing of the fundic wrap and the use of fibrin glue. MATERIAL AND METHODS Patients records of 258 patients were analyzed by an independent ob-server. Defective fundic wrap, recurrent oesophagitis and hiatal hernia were defined as failure. RESULTS Failure after Nissen fundoplication was found in 29 patients (14.9%). Crural closure (p = 0.021), anchoring of the wrap (p = 0.020) and fibrin glue (p = 0.029) decreased the incidence of failure. However, only crural closure (p = 0.010) and fibrin glue (p = 0.019) were independent factors in the prevention of failure. CONCLUSIONS Fibrin glue as a new method might be worth utilizing to further decrease the incidence of failure after Nissen fundoplication. Because our study was retrospective, prospective randomized study should be performed before universal use of fibrin glue in the prevention of failure after fundoplication.

Abstract
BACKGROUND Laparoscopic repair of a large hiatal hernia is technically challenging. A significant learning curve likely exists that has not been studied to date. METHODS Since 1992, the authors have prospectively collected data for all patients undergoing laparoscopic repair of a very large hiatal hernia (50% or more of the stomach within the chest). Follow-up evaluation was performed after 3 months, then yearly. Visual analog scores were used to assess heartburn and dysphagia. Patients were grouped according to institutional and individual surgeons' experience to determine the impact of any learning curve. The outcome for procedures performed by consultant surgeons was compared with that for trainees. RESULTS From 1992 to 2008, 415 patients with a 1-year minimum follow-up period were studied. Institutional and individual experience had a significant influence on operation time, conversion to open surgery, and length of hospital stay. However, except for heartburn scores during a 3-month follow-up evaluation of institutional experience (p=0.03), clinical outcomes were not influenced by either an institutional or individual learning curve. Furthermore, in general terms, whether the procedure was performed by a consultant or a supervised trainee had little effect on outcome. CONCLUSIONS Institutional and individual learning curves had no significant influence on clinical outcomes, although improved experience was reflected in improved operation time, conversion rate, and hospital stay. These outcomes improved over the first 50 institutional cases, and the outcomes for individual surgeons improved for up to 40 cases.

Abstract
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.

Abstract
INTRODUCTION Paraesophageal hernia (PEH) repair is a technically challenging operation. These patients are typically older and have more co-morbidities than patients undergoing anti-reflux operations for gastroesophageal reflux disease (GERD), and these factors are usually cited as the reason for worse outcomes for PEH patients. Clinically, it would be useful to identify potentially modifiable variables leading to improved outcomes. METHODS We performed a retrospective analysis of a representative sample from 37 states, using the Nationwide Inpatient Sample database over a 5-year period (2001-2005). Patients undergoing any anti-reflux operation with or without hiatal hernia repair were included, and comparison was made based on primary diagnoses of PEH or GERD. Exclusion criteria were diagnosis codes not associated with reflux disease or diaphragmatic hernia, emergency admissions, and age <18. Primary outcome was in-hospital mortality. Two sets of multivariate analyses were performed; one set adjusting for pre-treatment variables (age, gender, race, Charlson Comorbidity Index, hospital teaching status, hospital volume of anti-reflux surgery, calendar year) and a second set adjusting further for post-operative complications (splenectomy, esophageal laceration, pneumothorax, hemorrhage, cardiac, pulmonary, and thromboembolic events, (VTE)). RESULTS Of the 23,458 patients, 6,706 patients had PEH. PEH patients are older (60.4 vs. 49.1, p < 0.001) and have significantly more co-morbidities than GERD patients. On multivariate analysis, adjusting for pre-treatment variables, PEH patients are more likely to die and have significantly worse outcomes than GERD patients. However, further adjustment for pulmonary complications, VTE, and hemorrhage eliminates the mortality difference between PEH and GERD patients, while adjustment for cardiac complications or pneumothorax did not eliminate the difference. CONCLUSIONS While PEH patients have worse post-operative outcomes than GERD patients, we note that differences in mortality are explained by pulmonary complications, VTE, and hemorrhage. The impact of hemorrhagic complications on this group underscores the importance of careful dissection. Additionally, age and co-morbidities alone should not preclude a patient from PEH repair; rather, attention should be focused on peri-operative optimization of pulmonary status and prophylaxis of thromboembolic events.

Abstract
Studies from large volume centers of excellence have proven the efficacy of laparoscopic antireflux surgery. However, the majority of these operations are performed in community hospitals, where the results are more variable. Major issues potentially affecting laparoscopic antireflux surgery in community hospitals include a) the individual skills and experience of the surgeons, b) the volume of operations per surgeon and hospital, and c) the sophistication of the esophageal motility labs evaluating these patients prior to surgery. Another evolving issue is the increasing number of fundoplication failures and where best to evaluate and treat these patients.

Abstract
BACKGROUND/PURPOSE Recurrent gastroesophageal reflux disease (rGERD) is a common problem after fundoplication. Previous studies attempting to identify risk factors for rGERD have failed to control for confounding variables. The purpose of this study was to identify significant risk factors for rGERD after controlling for potential confounding variables. METHODS A retrospective, matched case-control study was conducted at a tertiary children's hospital. Cases (n = 116) met 1 of these criteria: reoperation for rGERD, symptomatic rGERD (confirmed by upper gastrointestinal series, esophagogastroduodenoscopy, or pH monitoring), or postoperative reinstitution of antireflux medication for more than 8 weeks. Controls (n = 209) were matched for surgeon, approach (laparoscopic/open), technique (partial/complete), and approximate operative date. Univariate and multivariable associations were analyzed by conditional logistic regression. RESULTS Significant risk factors for rGERD were age of less than 6 years (odds ratio [OR], 3.6; 95% confidence interval [CI], 1.7-7.5), preoperative hiatal hernia (OR, 3.2; 95% CI, 1.4-7.3), postoperative retching (OR, 5.1; 95% CI, 2.6-10.0), and postoperative esophageal dilatation (OR, 10.8; 95% CI, 1.8-65.4). Interestingly, significant association was not found between neurologic impairment and rGERD after controlling for potential confounding variables. CONCLUSION Age of less than 6 years, preoperative hiatal hernia, postoperative retching, and postoperative esophageal dilatation are independently associated with increased risk of rGERD. Neurologic impairment alone does not increase the risk of developing rGERD.

Abstract
The gynaecologist practising operative laparoscopy should be seen as part of a team that actively promotes patient safety, minimizing risks and optimizing outcomes. Building a culture of safety which focuses on proactive initiatives to manage risk and remove individual 'blame' should be an integral part of any operative laparoscopy unit. Thus, when adverse clinical incidents or outcomes occur, reporting of such events is encouraged and seen to be acceptable behaviour within the framework of complete patient care. By recognizing and analysing adverse outcomes, the team can develop strategies to prevent or manage a recurrence of such events. Implementing systems or solutions to prevent harm to patients is the cornerstone of any risk management programme. In this review, we discuss the development and implementation of risk management strategies in the clinical setting, and in particular how this applies to operative laparoscopy.

Abstract
BACKGROUND The ideal continuing professional development (CPD) model to transfer advanced minimally invasive surgical (MIS) skills to surgeons in practice has not yet been determined. METHODS A survey of general surgeons practicing in Alberta was conducted to determine attitudes toward CPD with a focus on MIS colon surgery. Two separate mailings of the survey were conducted in both hard copy and e-mail format. Data were collected and analyzed. RESULTS Seventy-one of 92 surveys were returned, yielding a response rate of 77%. The majority (62%) of surgeons had received their training while in practice. The most prevalent form of CPD was short courses, with 82% of surgeons having attended at least 1 short course in MIS. When directly comparing short courses with mentorship, 69% of respondents rated courses as less helpful, whereas 21% thought they were equivalent to mentorship. Sixty-one percent of surgeons are interested in a comprehensive approach, such as a mini-fellowship, to learning laparoscopic colorectal surgery. CONCLUSIONS General surgeons want access to different modalities of training, including both mentorship experiences and short courses. They are willing to take time away from their practices to learn new MIS skills. The best way to provide CPD to practicing surgeons is likely through a combination of teaching interventions, including courses, mentoring relationships, and the application of new technologies.

Abstract
Many studies have looked at the learning curve associated with laparoscopic Nissen fundoplication (LNF) in a given institution. This study looks at the learning curve of a single surgeon with a large cohort of patients over a 10-year period. Prospective data were collected on 400 patients undergoing laparoscopic fundoplication for over 10 years. The patients were grouped consecutively into cohorts of 50 patients. The operating time, the length of postoperative hospital stay, the conversion rate to open operation, the postoperative dilatation rate, and the reoperation rate were analyzed. Results showed that the mean length of operative time decreased from 143 min in the first 50 patients to 86 min in the last 50 patients. The mean postoperative length of hospital stay decreased from 3.7 days initially to 1.2 days latterly. There was a 14% conversion to open operation rate in the first cohort compared with a 2% rate in the last cohort. Fourteen percent of patients required reoperation in the first cohort and 6% in the last cohort. Sixteen percent required postoperative dilatation in the first cohort. None of the last 150 patients required dilatation. In conclusion, laparoscopic fundoplication is a safe and effective operation for patients with gastroesophageal reflux disease. New techniques and better instrumentation were introduced in the early era of LNF. The learning curve, however, continues well beyond the first 20 patients.

Surg Endosc 2007; 21:1377-82. [PMID: 17285370 DOI: 10.1007/s00464-006-9156-x] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2006] [Revised: 08/23/2006] [Accepted: 08/30/2006] [Indexed: 01/05/2023]
Abstract
BACKGROUND The adverse outcomes of laparoscopic fundoplication are more likely during the initial 20 cases performed by each individual surgeon. This study aimed to evaluate the impact of substantial surgical experience versus experience beyond the learning curve on the early and late objective and subjective results. METHODS The patients were divided into two groups according to the surgeon. In group 1 (n = 230), all the patients underwent surgery by a surgeon with substantial experience in laparoscopic fundoplication. In group 2 (n = 118), the patients were treated by a total of seven surgeons whose personal experience exceeded the individual learning curve, but was distinctively less than that of the group 1 surgeon. RESULTS The conversion rate was 2.2% in group 1 and 4.4% in group 2. The median operating time was 65 min in group 1 and 70 min in group 2 (p = 0.0020). The occurrence of immediate complications was 3.5% in group 1 and 7.6% in group 2 (p = 0.0892). At 6 months after surgery, 7.4% of the patients in group 1 and 16.1% of the patients in group 2 reported that dysphagia disturbed their daily lives (p = 0.0115). The late subjective results, including postoperative symptoms and evaluation of the surgical result, were similar in the two groups. CONCLUSIONS Substantial experience with the procedure is associated with a shorter operating time and somewhat fewer complications, conversions, and early dysphagia episodes. This supports the provision of expert supervision even after the initial learning phase of 20 individual procedures. The patients' long-term subjective symptomatic outcome was similar in the two groups. Substantial experience does not provide better late results than surgical experience beyond the learning curve.

Abstract
OBJETIVO: A fundoplicatura laparoscópica a 360º é o tratamento de escolha para pacientes com doença do refluxo gastroesofágico que não respondem bem ao tratamento clínico. Este artigo demonstra a curva de aprendizado durante a Residência Médica em Cirurgia Geral. MÉTODO: Foi realizada uma análise retrospectiva de 60 pacientes submetidos à fundoplicatura laparoscópica durante o período de março a outubro de 2005. Os pacientes foram divididos em dois grupos: 30 casos iniciais que foram comparados aos 30 casos subseqüentes. As variáveis analisadas incluíram: tempo operatório, taxa de conversão, complicações e tempo de hospitalização. RESULTADOS: A fundoplicatura laparoscópica foi realizada em 18 homens e 42 mulheres, com idade média de 48,3 anos. Comparando os dois grupos, houve diferença estatisticamente significativa no tempo operatório total (92,7 vs. 76,7 minutos, p=0,003), no tempo operatório para a operação de Nissen-Rossetti (86,7 vs. 68,4 minutos, p=0,00006) e no tempo para a liberação dos vasos gástricos curtos (22 vs. 13,1 minutos, p=0,00005). As complicações intra-operatórias foram maiores no primeiro grupo de pacientes, mas a diferença não foi estatisticamente significativa (p=0,2). Todos os procedimentos foram concluídos com sucesso por vídeo-laparoscopia em ambos os grupos, e a mortalidade foi nula nesta série. A alta hospitalar ocorreu em média no primeiro dia de pós-operatório em ambos os grupos (p=0,06). CONCLUSÃO: A fundoplicatura laparoscópica pode ser realizada com segurança por um cirurgião em formação, sob supervisão direta de um titular, com mínima morbidade para os pacientes. A curva de aprendizado foi demonstrada, avaliando-se principalmente, o tempo operatório do procedimento.

Abstract
BACKGROUND Several studies have demonstrated laparoscopic antireflux surgery (LAS) for the treatment of gastroesophageal reflux disease (GERD) to be efficient at short- and midterm follow-up evaluations. The aim of this study was to evaluate the results for LAS 10 years after surgery. METHODS The 100 consecutive patients who underwent LAS by a single surgeon in 1993 were entered into a prospective database. Nissen fundoplication was performed for 68 patients, and partial posterior fundoplication (modified Toupet procedure) was performed for 32 patients. Evaluations of the outcome were made 5 and 10 years after surgery. A structured symptom questionnaire and upper gastrointestinal barium series were used at 5 years. The same questionnaire and an added quality-of-life questionnaire (the Gastrointestinal Quality of Life Index [GIQLI]) were used at 10 years. RESULTS Seven patients died of unrelated causes during the 10-year period. Four patients underwent revision surgery: one patient for persistent dysphagia and three patients for recurrent reflux symptoms. Three patients were lost to any follow-up study. At 5 years, 93% of the patients were free of significant reflux symptoms. At 10 years, 89.5% of the patients still were free of significant reflux (93.3% after Nissen, 81.8% after Toupet). Major side effects (flatulence and abdominal distension) were related to "wind" problems. The GIQLI scores at 10 years were significantly better than the preoperative scores of the patients under medical therapy with proton pump inhibitors. CONCLUSIONS Elimination of GERD symptoms improved quality of life and eliminated the need for daily acid suppression in most patients. These results, apparent 5 years after the operation, still were valid at 10 years.

Abstract
BACKGROUND Laparoscopic fundoplication for gastroesophageal reflux disease is a procedure associated with specific complications, especially in a surgeon's early experience. The learning curve of this procedure was examined at a tertiary community institution. METHODS A retrospective review of the first 100 cases performed at Royal Columbian Hospital was conducted. Two surgeons performed the majority of cases and routinely assisted each other. Patients were grouped chronologically with the first 50 cases defined as early institutional experience and a surgeon's first 20 cases defined as early personal experience. RESULTS Operative time was longer in both the early institutional (117.8 versus 91.3 minutes, P < .001) and personal experience (126.8 versus 89.7 minutes, P < .001). The rate of dysphagia requiring intervention was higher during the early institutional (22% versus 4%, P = .017) but not personal experience (19% versus 8%, P = not significant). The conversion rate was 0%, reoperation rate was 1%, mean length of stay was 2.5 +/- 1.4 days, and the readmission rate was 5%; these outcomes were unaffected by the learning curve. CONCLUSIONS There is a definable learning curve in laparoscopic fundoplication in terms of operative time. However, an acceleration of the personal learning curve in terms of dysphagia was observed with a two-surgeon collaborative approach. With careful patient selection conversion, reoperation, readmission, and complication rates equivalent to experienced centers can be achieved in the community setting early in the personal and institutional experience.

Abstract
BACKGROUND For all surgical procedures, a surgeons' learning curve can be anticipated during which complication rates are increased. The aims of this study were to evaluate individual learning curves for a group of surgeons performing laparoscopic fundoplication and to evaluate if the Procedicus MIST-simulator (Mentice Inc., Göteborg, Sweden) accurately predicts surgical performance. METHODS Twelve Nordic centers participated, each contributing with a "master" and a "pupil" surgeon. The pupils were tested in the simulator and thereafter performed their first 20 supervised operations. All procedures were videotaped and evaluated by 3 independent reviewers. RESULTS A significant decrease in operative time (P <0.001) and a trend (P = 0.12) toward improved score were seen during the series. The master significantly affected the pupil's score (P =0.0137). The simulator-test showed no correlation with the operative score. CONCLUSIONS Individual learning curves varied, and the teacher was shown to be the most important factor influencing the pupil's performance score. The correlation between assessed performance and patient outcome will be further investigated.

Abstract
Gastroenterologists may be called upon to manage patients who have had antireflux surgery that failed. The available literature on this topic comprises predominantly reports on retrospective, observational studies written by surgeons who often have focused on how technical deficiencies in performing the operation led to the failure. Such reports are of limited value to the gastroenterologist seeking guidance on patient management. Furthermore, comparisons among the reports are confounded by the lack of a standardized definition for failed antireflux surgery. This report critically reviews the available literature, and suggests a practical approach to the management of patients who have symptoms that were not completely relieved, that reappeared later, or that were caused by antireflux surgery.

Abstract
BACKGROUND Although the degree of surgical experience clearly affects early outcome of laparoscopic antireflux surgery, its influence on long-term results has not been fully evaluated. The aim of this study was to verify whether the initial experience in laparoscopic antireflux surgery could also influence the late clinical outcome. METHODS Clinical and endoscopic findings, together with quality of life, of the first 25 patients successfully submitted to laparoscopic fundoplication were compared with those of 25 matched controls operated on later. RESULTS At more than 2 years', follow-up, reflux symptoms, endoscopic findings, use of antisecretory drugs, side effects, and quality of life were not significantly different in both groups, despite a high occurrence of major anatomical failures (three vs one) in the first set of patients. CONCLUSION The late clinical outcome of patients with gastroesophageal disease operated on during the learning phase or after gaining experience is not different, provided the surgeon is adequately trained in laparoscopic surgery.

Abstract
PURPOSE The aim of this study was to quantify the learning curve in laparoscopic surgery. METHODS A systematic review of the evidence using a defined search strategy (PubMed, Medline, OVID, Embase, ERIC, Cochrane databases) was performed. Studies without statistical evaluation of the learning curve and opinion articles were excluded. The authors analysed 7 common laparoscopic procedures: cholecystectomy, fundoplication, colectomy, herniorrhaphy, splenectomy, appendicectomy, and pyloromyotomy. The "initial" and "late" stages of experience were compared with regards to the following outcome measures: operating time, conversion rate, complication rate, and length of stay in hospital. RESULTS A total of 3,641 articles were reviewed, of which, 37 (25,777 patients) fulfilled the entry criteria (5 in children). In all articles, the definition of proficiency was subjective, and the number of operations required to reach it was highly variable. There were improvements in all 4 outcome measures for cholecystectomy, fundoplication, colectomy, herniorrhaphy, and splenectomy between the "initial" and "late" experience. No data were available for the learning curves in appendicectomy or pyloromyotomy. CONCLUSIONS The number of procedures required to reach proficiency in laparoscopic surgery has not been defined clearly. These findings are important for training, ethical and medico-legal issues.

Abstract
BACKGROUND The population level frequency of adverse events after antireflux procedures and its relationship to surgical experience has not been well studied. STUDY DESIGN Two parallel retrospective, population-based cohort studies were conducted using the Washington State discharge database and the United States Health Care Utilization Project (HCUP) database. All adult patients assigned ICD-9 procedure codes for antireflux surgery from 1992 to 1997 were included. The frequency of case fatality, splenectomy, and esophageal injury was measured. In Washington State, the relationship of adverse outcomes to the cumulative number of procedures performed by a given surgeon (case-order) was determined. RESULTS Nationwide, an estimated 86,411 patients underwent antireflux surgery between 1992 and 1997. Splenectomy was performed in 2.3%, suture of esophageal laceration in 1.1%, and in-hospital death occurred in 0.8%. Adverse events were significantly more likely when procedures at case-order less than or equal to 15 (median) were compared with those at case-order greater than 15. As case-order increased by 1, the risk of death decreased by 1.7% (p = 0.001), and the risk of splenectomy and injury repair decreased by 1.6% (p = 0.001). If performed at case-order less than 15, the odds ofsplenectomy were 2.7 times, esophageal laceration repair 2.3 times, and death 5.6 times greater than the odds of adverse outcomes for procedures performed at later case-orders. CONCLUSIONS On a national level, morbidity and mortality associated with antireflux surgery performed in the 1 990s was quite low, but was somewhat higher than suggested by case series. Surgical experience with the procedure was linked to better outcomes.

Abstract
PURPOSE This study was undertaken to determine whether conversion or early reoperation contributed significantly to the eventual outcome of laparoscopic Nissen fundoplication. PATIENTS AND METHODS An independent surgeon, blinded to the operative events, administered two general and one system-specific quality of life tools to the first 100 consecutive patients booked for laparoscopic fundoplication in a community hospital, where the open conversion rate was 4 patients/surgeon and the early reoperation rate 1.5 patients/surgeon for the first 20 operations. Patients were also asked about need for medication, dysphagia, satisfaction (analog scale), and whether, if given it to do over, they would opt for surgery again. RESULTS Of the original 100 patients, 40 were studied an average of 5 years after surgery: 26 completed laparoscopically and 14 with laparoscopic failure (13 conversions and 1 early reoperation). Patient characteristics in the two groups were similar, except that there were more older patients with more fixed intrathoracic hiatus hernias in the failure group. Among the parameters examined, no statistically significant differences could be detected between laparoscopic and converted patients. CONCLUSIONS General and system-specific quality of life, digestive symptoms, need for medication, patient satisfaction, and willingness to have surgery over again are not altered by conversion or reoperation. Thus, surgeons who have adequate laparoscopic skills, experience with open fundoplication, and training in laparoscopic Nissen fundoplication should feel free to add it to their repertoires provided the likelihood of conversion and reoperation secondary to inexperience is understood by the patient.

Abstract
BACKGROUND This study examines the factors related to infection and incisional herniation after laparoscopy at the umbilicus, as compared with those at remote sites. METHODS From a prospective database of 561 cholecystectomies, 190 inguinal hernia repairs, 71 Nissen fundoplications, and 51 ventral hernia repairs, 873 consecutive Hasson cannula sites, 748 umbilicus sites, and 125 remote sites were analyzed. RESULTS The wound infection rate was found to be 6%: 7% at the umbilicus (9% after cholecystectomy and 2% after other operations [p < 0.05]) and 0% at remote sites (p < 0.05). Excluding cholecystectomy, the umbilical infection rate was 2%, similar to that at remote sites. The postoperative ventral hernia rate was at 0.8%, the same at the umbilicus as elsewhere. The rate was similar for gallbladder and nongallbladder operations and correlated with the postoperative wound infection rate, but not with the preexisting fascial defect rate. CONCLUSIONS Wound infection at the umbilicus is similar to that at other sites, except after cholecystectomy. Postoperative ventral hernia at the umbilicus is similar to that at other sites and not related to preexisting fascial defects.

Abstract
Over the last decade, the laparoscopic approach to antireflux surgery has been widely applied, resulting in improved early outcomes and greater patient acceptance of surgery for gastroesophageal reflux disease. However, although short-term outcomes are probably better overall than those following open surgery, it has become apparent that the laparoscopic approach is associated with an increased risk of some complications, and as well as the occurrence of new complications specific to the laparoscopic approach. Significant complications include acute paraesophageal hiatus herniation, severe dysphagia, pneumothorax, vascular injury, and perforation of the gastrointestinal tract. The incidence of some of these complications decreases as surgeons gain experience; others can be minimized by using an appropriate operative technique. In addition, laparoscopic reintervention is usually straightforward in the 1st postoperative week. For this reason, the surgeon should have a low threshold for early laparoscopic reexploration, facilitated by early radiological contrast studies, in order to reduce the likelihood that problems will arise later.

Abstract
BACKGROUND A small number of patients fail fundoplication and require reoperation. Laparoscopic techniques have been applied to reoperative fundoplications. We reviewed our experience with reoperative laparoscopic fundoplication. METHODS Reoperative laparoscopic fundoplication was undertaken in 28 patients, 19 F and 9 M, of mean age 56 years +/- 12. Previous antireflux procedures included 19 open and 12 laparoscopic antireflux operations. RESULTS Symptoms were heartburn (90%), dysphagia (35%), and atypical symptoms (30%%). The mean interval from antireflux procedure to revision was 13 months +/- 4.2. The mean DeMeester score was 78+/-32 (normal 14.7). Eighteen patients (64%) had hiatal breakdown, 17 (60%) had wrap failure, 2 (7%) had slipped Nissen, 3 (11%) had paraesophageal hernias, and 1 (3%) had an excessively tight wrap. Twenty-five revisions were completed laparoscopically, while 3 patients required conversion to the open technique. Complications occurred in 9 of 17 (53%) patients failing previous open fundoplications and in 4 of 12 patients (33%) failing previous laparoscopic fundoplications and included 15 gastrotomies and 1 esophagotomy, all repaired laparoscopically, 3 postoperative gastric leaks, and 4 pneumothoraces requiring tube thoracostomy. No deaths occurred. Median length of stay was 5 days (range 2-90 days). At a mean follow-up of 20 months +/- 17, 2 patients (7%) have failed revision of their fundoplications, with the rest of the patients being essentially asymptomatic (93%). CONCLUSIONS The results achieved with reoperative laparoscopic fundoplication are similar to those of primary laparoscopic fundoplications. Laparoscopic reoperations, particularly of primary open fundoplication, can be technically challenging and fraught with complications.

Abstract
BACKGROUND Electrosurgery is one of the most commonly used energy systems in laparoscopic surgery. Two major categories of potential complications related to electrosurgery in laparoscopy are mechanical trauma and electrothermal injury. The latter can result from unrecognized energy transfer in the operational field or, less commonly, to unnoticed stray current outside the laparoscopic field of view. Stray current can result from insulation failure, direct coupling, or capacitive coupling. METHODS We reviewed the literature concerning essential biophysics of electrosurgery, including electrosurgical waveform differentiation, tissue effect, and variables that determine tissue effect. The incidence of electrosurgical injuries and possible mechanisms responsible for the injuries are discussed. Different types of injuries may result in different clinical manifestations and histopathological findings. Gross and microscopic pathological check-ups of the injury sites may distinguish between different mechanisms, and thus provide further clues postoperatively. RESULTS Several recommended practices are proposed to avoid electrosurgical injury laparoscopically. To achieve electrosurgical safety and to prevent electrosurgical injuries, the surgical team should have a good understanding of the biophysics of electrosurgery, the basis of equipment and general tissue effects, as well as the surgeon's spatial orientation and hand-eye coordination. Some intraoperative adjuvant procedures and newly developed safety devices have become available may aid to improve electrosurgical safety. CONCLUSIONS Knowledge of the biophysics of electrosurgery and the mechanisms of electrosurgical injury is important in recognizing potential complications of electrosurgery in laparoscopy. Procedures for prevention, intraoperative adjuvant maneuvers, early recognition of the injury with in-time salvage treatment, and alertness to postoperative warning signs can help reduce such complications.
