Abstract
BACKGROUND Surgical trainees are required to develop competency in a variety of laparoscopic operations. Developing laparoscopic technical skills can be difficult as there has been a decrease in the number of procedures performed. This study aims to develop an inexpensive and anatomically relevant model for training in laparoscopic foregut procedures. METHODS An ex vivo, anatomic model of the human upper abdomen was developed using intact porcine esophagus, stomach, diaphragm and spleen. The Toronto lap-Nissen simulator was contained in a laparoscopic box-trainer and included an arch system to simulate the normal radial shape and tension of the diaphragm. We integrated the use of this training model as a part of our laparoscopic skills laboratory-training curriculum. Afterwards, we surveyed trainees to evaluate the observed benefit of the learning session. RESULTS Twenty-five trainees and five faculty members completed a survey regarding the use of this model. Among the trainees, only 4 (16%) had experience with laparoscopic Heller myotomy and Nissen fundoplication. They reported that practicing with the model was a valuable use of their limited time, repeating the exercise would be of additional benefit, and that the exercise improved their ability to perform or assist in an actual case in the operating room. Significant improvements were found in the following subjective measures comparing pre- vs. post-training: (I) knowledge level (5.6 vs. 8.0, P<0.001); (II) comfort level in assisting (6.3 vs. 7.6, P<0.001); and (III) comfort level in performing as the primary surgeon (4.9 vs. 7.1, P<0.001). The trainees and faculty members agreed that this model was of adequate fidelity and was a representative simulation of actual human anatomy. CONCLUSIONS We developed an easily reproducible training model for laparoscopic procedures. This simulator reproduces human anatomy and increases the trainees' comfort level in performing and assisting with myotomy and fundoplication.

Abstract
OBJECTIVE To analyze the surgical proficiency and educational quality of YouTube videos demonstrating laparoscopic fundoplication (LF). DESIGN In this cross-sectional study, a search was performed on YouTube for videos demonstrating the LF procedure. The surgical and educational proficiency was evaluated using the objective component rating scale, the educational quality rating score, and total video quality score. Statistical significance was determined by analysis of variance, receiver operating characteristic curve, and odds ratio analysis. RESULTS A total of 71 videos were included in the study; 28 (39.4%) videos were evaluated as good, 23 (32.4%) were moderate, and 20 (28.2%) were poor. Good-rated videos were significantly longer (good, 22.0 ± 5.2min; moderate, 7.8 ± 0.9min; poor, 8.5 ± 1.0min; p = 0.007) and video duration was predictive of good quality (AUC, 0.672 ± 0.067; 95% CI: 0.541-0.802; p = 0.015). For good quality, the cut-off video duration was 7:42 minute. This cut-off value had a sensitivity of 67.9%, a specificity of 60.5%, and an odds ratio of 3.23 (95% CI: 1.19-8.79; p = 0.022) in predicting good quality. Videos uploaded from industrial sources and with a higher views/days online ratio had a higher objective component rating scale and total video quality score. In contrast, the likes/dislikes ratio was not predictive of video quality. CONCLUSIONS Many videos showing the LF procedure have been uploaded to YouTube with varying degrees of quality. A process for filtering LF videos with high surgical and educational quality is feasible by evaluating the video duration, uploading source, and the views/days online ratio. However, alternative videos platforms aimed at professionals should also be considered for educational purposes.

Abstract
BACKGROUND Minimally invasive procedures have become common, and more reoperations for failed antireflux procedures are performed laparoscopically. We wanted to study the outcomes of laparoscopic reoperations for reflux. METHODS Medical records of all patients who underwent reoperation without esophageal resection after previous antireflux procedures between January 2000 and October 2012 were reviewed. RESULTS Seventy-five patients were included in this report: 56 (77%) women and 19 (23%) men. Median age was 58 years. The previous operation was laparoscopic antireflux procedures in 65 (87%) patients. The median interval between the last antireflux procedure and laparoscopic reoperation was 42 months. The median body mass index (BMI) was 28.7. All patients were symptomatic. Intraoperative findings included recurrent hiatal hernia in 47 (63%) patients, incompetent fundoplication in 14 (19%) patients, tight fundoplication in 8 (11%) patients, and tight crura in 2 (3%) patients. Laparoscopic Nissen fundoplication was performed in 57 (76%) patients, partial posterior fundoplication was performed in 12 (16%) patients, partial anterior fundoplication was performed in 3 (4%) patients, removal of crural stitches was performed in 2 patients, and a combination of partial posterior fundoplication and removal of crural stiches was performed in 1 patient. Complications occurred in 13 (15%) patients. Improvement in symptoms was observed in 70 (93%) patients in early postoperative follow-up and in 59 (78%) patients in long-term follow-up. Functional results were classified as excellent in 59 (78%) patients, good in 6 (7%) patients, fair in 7 (8%) patients, and poor in 3 (4%) patients. CONCLUSIONS Laparoscopic reoperation for failed antireflux operations is a complex procedure, but it is safe and effective in selected patients. Reoperation after a failed antireflux repair results in excellent or good functional status in a majority of patients, but these results may deteriorate over time.

Abstract
OBJECTIVE To update the themes of endoscopic and surgical treatment of Gastroesophageal Reflux Disease (GERD) from the Mexican Consensus published in 2002. METHODS Part I of the 2011 Consensus dealt with the general concepts, diagnosis, and medical treatment of this disease. Part II covers the topics of the endoscopic and surgical treatment of GERD. In this second part, an expert in endoscopy and an expert in GERD surgery, along with the three general coordinators of the consensus, carried out an extensive bibliographic review using the Embase, Cochrane, and Medline databases. Statements referring to the main aspects of endoscopic and surgical treatment of this disease were elaborated and submitted to specialists for their consideration and vote, utilizing the modified Delphi method. The statements were accepted into the consensus if the level of agreement was 67% or higher. RESULTS Twenty-five statements corresponding to the endoscopic and surgical treatment of GERD resulted from the voting process, and they are presented herein as Part II of the consensus. The majority of the statements had an average level of agreement approaching 90%. CONCLUSION Currently, endoscopic treatment of GERD should not be regarded as an option, given that the clinical results at 3 and 5 years have not demonstrated durability or sustained symptom remission. The surgical indications for GERD are well established; only those patients meeting the full criteria should be candidates and their surgery should be performed by experts.

Abstract
BACKGROUND Electrical stimulation of the lower esophageal sphincter (LES) improves LES pressure without interfering with LES relaxation. The aim of this open-label pilot trial was to evaluate the safety and efficacy of long-term LES stimulation using a permanently implanted LES stimulator in patients with gastroesophageal reflux disease (GERD). METHODS GERD patients who were at least partially responsive to proton pump inhibitors (PPI) with abnormal esophageal pH, hiatal hernia ≤ 3 cm, and esophagitis ≤ LA grade C were included. Bipolar stitch electrodes were placed in the LES and an IPG was placed in a subcutaneous pocket. Electrical stimulation was delivered at 20 Hz, 215 μs, 3-8 mA in 30 min sessions. The number and timing of sessions was tailored to each patient's GERD profile. Patients were evaluated using GERD-HRQL, daily symptom and medication diaries, SF-12, esophageal pH, and high-resolution manometry. RESULTS 24 patients (mean age = 53 years, SD = 12 years; 14 men) were implanted; 23 completed their 6-month evaluation. Median GERD-HRQL scores at 6 months was 2.0 (IQR = 0-5.5) and was significantly better than both baseline on-PPI [9.0 (range = 6.0-10.0); p < 0.001] and off-PPI [23 (21-25); p < 0.001] GERD-HRQL. Median% 24-h esophageal pH < 4.0 at baseline was 10.1 and improved to 5.1 at 6 months (p < 0.001). At their 6-month follow-up, 91 % (21/23) of the patients were off PPI and had significantly better median GERD-HRQL on LES stimulation compared to their on-PPI GERD-HRQL at baseline (9.0 vs. 2.0; p < 0.001). There were no unanticipated implantation- or stimulation-related adverse events or untoward sensation due to stimulation. There were no reports of treatment-related dysphagia, and manometric swallow was also unaffected. CONCLUSIONS Electrical stimulation of the LES is safe and effective for treating GERD. There is a significant and sustained improvement in GERD symptoms, esophageal pH, and reduction in PPI usage without any side effects with the therapy. Furthermore, the therapy can be optimized to address an individual patient's disease.

Abstract
Gastroesophageal reflux (GER) affects ∼10-20% of American adults. Although symptoms are equally common in men and women, we hypothesized that sex influences diagnostic and therapeutic approaches in patients with GER. PubMed database between 1997 and October 2011 was searched for English language studies describing symptoms, consultative visits, endoscopic findings, use and results of ambulatory pH study, and surgical therapy for GER. Using data from Nationwide Inpatient Sample, Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality, we determined the sex distribution for admissions and reflux surgery between 1997 and 2008. Studies on symptoms or consultative visits did not show sex-specific differences. Even though women are less likely to have esophagitis or Barrett's esophagus, endoscopic studies enrolled as many women as men, and women were more likely to undergo ambulatory pH studies with a female predominance in studies from the US. Surgical GER treatment is more commonly performed in men. However, studies from the US showed an equal sex distribution, with Nationwide Inpatient Sample data demonstrating an increase in women who accounted for 63% of the annual fundoplications in 2008. Despite less common or severe mucosal disease, women are more likely to undergo invasive diagnostic testing. In the US, women are also more likely to undergo antireflux surgery. These results suggest that healthcare-seeking behavior and socioeconomic factors rather than the biology of disease influence the clinical approaches to reflux disease.

Abstract
BACKGROUND This study was designed to determine whether there is a learning curve for laparoscopic cardiomyotomy for the treatment of achalasia. METHODS All patients who underwent a primary laparoscopic cardiomyotomy for achalasia between 1992 and 2006 in our hospitals were identified from a prospective database. The institutional and the individual surgeon's learning experiences were assessed based on operative and clinical outcome parameters. The outcomes of cardiomyotomies performed by consultant surgeons versus supervised trainees also were compared. RESULTS A total of 186 patients met the inclusion criteria; 144 procedures were undertaken by consultant surgeons and 42 by a surgical trainee. The length of operation decreased after the first ten cases in both the institutional and each individual experience. The rate of conversion to open surgery also was significantly higher in the first 20 cases performed. Intraoperative complications, overall satisfaction with the outcome, reoperation rate, and postoperative dysphagia were not associated with the institutional or the surgeon's operative experience. Although the length of the operation was greater for surgical trainees (93 versus 79 minutes; p < 0.01), no differences in outcome between the operations performed by consultant surgeons and surgical trainees were detected. CONCLUSION An institutional (20 cases) and an individual (10 cases) learning curve for laparoscopic cardiomyotomy for achalasia can be defined. The clinical outcome for laparoscopic cardiomyotomy does not differ between supervised surgical trainees and consultant surgeons.

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
BACKGROUND Laparoscopic Toupet fundoplication (TF) is reported to be as effective as Nissen (NF), but to be associated with fewer unfavorable postoperative side-effects. This study evaluates the one- and three-year clinical outcome of 140 randomized patients after a laparoscopic NF or TF. PATIENTS AND METHODS Inclusion criteria included patients over 16 years old with complications of gastro-oesophageal reflux disease (GORD) and persistence or recurrence of symptoms after three months of treatment. Subjects with a previous history of gastric surgery or repeated fundoplication, brachy-oesophagus or severe abnormal manometry results were excluded. Seventy-seven NF and 63 TF were performed. The severity of symptoms was assessed before and after the procedure. RESULTS One hundred and twenty-one of the 140 patients after one year, and 118 after three years, were evaluated and no statistically significant clinical difference was observed. The level of satisfaction concerning the outcome of the operation remained high after one or three years regardless of the type of fundoplication performed. CONCLUSIONS Functional complications after NF are not avoided with TF.

Ohnmacht GA, Deschamps C, Cassivi SD, Nichols FC, Allen MS, Schleck CD, Pairolero PC. Failed antireflux surgery: results after reoperation. Ann Thorac Surg 2007; 81:2050-3; discussion 2053-4. [PMID: 16731129 DOI: 10.1016/j.athoracsur.2006.01.019] [Citation(s) in RCA: 46] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/11/2005] [Revised: 01/03/2006] [Accepted: 01/04/2006] [Indexed: 12/17/2022]
Abstract
BACKGROUND Since laparoscopy has become a common surgical approach for antireflux surgery, little is known regarding reoperation for failed antireflux surgery. METHODS Records of all patients who underwent reoperation without esophageal resection for symptoms of recurrent gastroesophageal reflux disease or hiatal hernia between July 1, 1995 and April 1, 2004 were reviewed. There were 126 patients. Two patients declined research participation. The remaining 124 patients (71 women and 53 men) formed the basis for this study. Median age was 53 years (range, 19 to 83 years). The initial operation was a laparoscopic antireflux procedure in 76 patients (61.3%) and an open repair in 48 (38.7%). A single previous operation had been done in 100 patients, two operations in 20, and three operations in 4. The median interval between the most recent reoperation and the previous operation was 28 months. All patients were symptomatic. The surgical approach was a thoracotomy in 83 patients, laparotomy in 36, laparoscopy in 4, and thoracoabdominal in 1. A Nissen fundoplication was performed in 86 patients (69.4%), Belsey fundoplication in 31(25.0%), and others in 7. RESULTS There were no operative deaths. Complications occurred in 27 patients (21.7%). Median hospitalization was 6 days (range, 5 to 58 days). Follow-up ranged from 10 days to 10 years (median, 9.7 months). Improvement was observed in 114 patients (91.9%). Functional results were classified as excellent in 69 patients (55.6%), good in 19 (15.4%), fair in 26 (20.9%), and poor in 10 (8.1%). No single operative approach was functionally superior. CONCLUSIONS We conclude that reoperation for failed antireflux surgery is safe and effective. Results of reoperation were not affected by the type of reoperation or whether the previous approach was laparoscopic or open.

Abstract
BACKGROUND We sought to determine whether subjective outcomes one or more years after antireflux surgery are affected by the operating surgeon. METHODS We reviewed records of patients who had antireflux surgery from June 2000 to June 2002 and mailed the patients a 19-item survey that focused on current medication use, postoperative symptom improvement, and satisfaction with surgery. We tested the significance of predictor variables using chi-squared and Fisher exact tests for categorical variables and analysis of variance for continuous variables. RESULTS We mailed the survey to 74 patients. Ninety-one percent of the operations were initially laparoscopic, with 5 (7%) subsequently converting to open. Ninety-five percent of patients were taking protein pump inhibitors (PPIs) preoperatively. Surgeons (n = 7) were divided into four groups, with the four surgeons who did two or fewer procedures in one group. Fifty-two of 74 patients (70%) responded to the survey (mean age, [SD] 44 [21] years, 37% male). The mean duration of followup was 2.1 [0.46] years. Thirty-eight percent of patients were taking medications for gastroesophageal reflux disease at the time of survey completion. It was found that the surgeon had an influence on patients' perceptions of the success of the surgery and whether having surgery was a good idea. We did not identify a statistically significant effect of the surgeon on preoperative symptom severity, postoperative ability to belch, dysphagia, medication use, and lifestyle. CONCLUSION A patient's surgeon has an effect on satisfaction with antireflux surgery. Further research should clarify specific practices of the surgeon (patient selection, operative technique, followup) associated with best outcome.

Ann Thorac Surg 2006; 80:1191-4; discussion 1194-5. [PMID: 16181839 DOI: 10.1016/j.athoracsur.2005.04.008] [Citation(s) in RCA: 36] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2005] [Revised: 04/03/2005] [Accepted: 04/04/2005] [Indexed: 12/23/2022]
Abstract
BACKGROUND We reviewed our experience and analyzed factors affecting functional results after laparoscopic esophageal myotomy (LEM) for achalasia. METHODS From January 1996 through October 2003, the records of 211 patients (110 men and 101 women) who had LEM for achalasia were reviewed, and factors affecting morbidity and functional results were analyzed. RESULTS Median age was 47 years (range, 12 to 85). One hundred and twenty-five patients (59%) had prior esophageal dilatation and/or botulinum toxin injection and 19 (9%) had a prior myotomy. A partial fundoplication was performed in 198 patients (94%); posterior in 135 and anterior in 63. Median operative time was 208 minutes (range, 90 to 527). Intraoperative complications occurred in 37 patients (17.5%), and included mucosal perforation in 32, pneumothorax in 2, and retained needle, splenic capsular tear, and gastric short vessel bleeding in 1 each. Five patients (2%) required conversion to an open procedure. Postoperative complications occurred in 17 patients (8%) including 2 patients who required reoperation for leak. There were no perioperative deaths. Median hospitalization was 3 days (range, 1 to 48). Follow-up was complete in 167 patients (79%) and ranged from 1 to 70.5 months (median, 5.3). Functional results were classified as excellent in 105 patients (63%), good in 43 (26 %), and fair or poor in 19 (11%). Previous esophageal surgery for achalasia adversely affected functional results (p = 0.0139). Preoperative bougie dilatation (p = 0.9851), pneumatic dilatation (p = 0.8548), botulinum toxin injection (p = 0.1724), and the type of fundoplication (p = 0.5904) did not affect functional results. Preoperative bougie dilatation (p = 0.441), pneumatic dilatation (p = 0.1060), and botulinum toxin injection (p = 0.3938) did not affect the incidence of intraoperative perforation. As experience is gained, the incidence of intraoperative complications has decreased significantly (p = 0.0075). CONCLUSIONS Laparoscopic myotomy for achalasia is safe and effective in the majority of patients. The incidence of intraoperative complications decreases as experience is gained. Preoperative endoscopic treatment does not preclude successful surgical outcome. Excellent or good functional results are achieved in the majority of patients although previous surgical treatment adversely affects functional results.

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
INTRODUCTION The aim of this study was to evaluate the long term efficacy of laparoscopic treatment of gastroesophageal reflux disease (GERD). PATIENT AND METHODS Between 1(st) January 1992 and 31 December 1996, 161 patients underwent complete or partial laparoscopic fundoplication for a symptomatic GERD. One hundred and twenty three patients were submitted to Nissen-Rossetti fundoplication, 26 patients to Nissen fundoplication and 12 patients to a partial posterior Toupet fundoplication.141 patients were evaluated at 3 months, 2-years and 5-years. Since undergoing the operation, four patients died of unrelated causes, 16 patients could not be contacted for follow up (10%). pH monitoring and oesophageal manometry were performed preoperatively and at 3 months postoperatively. The patients were evaluated 2 and 5-years after surgery by specific phone questionnaire. RESULTS There was no mortality, the morbidity rate was 1.2% and the conversion rate was 5%. Incidence of dysphagia 3 months after surgery was 23.4%, and 5-years after 12%; 12% of patients had recurrent symptoms at 5 years. CONCLUSION The overall satisfaction rate at 5 years was 91.4%. Nissen-Rossetti fundoplication seems to have better results at 5-years regarding postoperative dysphagia and symptoms recurrence.

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
BACKGROUND To review our early operative results and endoscopic findings after laparoscopic fundoplication for Barrett's esophagus (BE). METHODS From January 1995 through December 2000, 49 patients with BE (35 men and 14 women) underwent laparoscopic antireflux surgery. Median age was 54 years (range, 28 to 85 years). No patient had high-grade dysplasia; 6, however, had low-grade dysplasia. All 49 patients had gastroesophageal reflux symptoms. Heartburn was present in 41 patients (84%), dysphagia in 16 (33%), epigastric or chest pain in 9 (18%), and other symptoms in 16 (33%). A Nissen fundoplication was performed in 48 patients and a partial posterior fundoplication in 1. Forty-one patients (84%) had concomitant hiatal hernia repair. RESULTS There were no deaths. Complications occurred in 2 patients (4%). Follow-up was complete in 48 patients (98%) and ranged from 1 to 81 months (median, 29 months). Functional results were classified as excellent in 33 patients (69%), good in 9 (19%), fair in 5 (10%), and poor in 1 (2%). Thirty-three patients (67%) underwent postoperative surveillance esophagoscopy with biopsy. Nine patients (18%) had total regression of BE and 3 (6%) had a decrease in total length. In the 6 patients with preoperative low-grade dysplasia, dysplasia was not found in 4, remained unchanged in 1, and progressed to in situ adenocarcinoma in 1. CONCLUSIONS Laparoscopic fundoplication is effective in controlling symptoms in the majority of patients with BE. While disappearance of BE may occur in some patients, the possibility of developing esophageal adenocarcinoma is not eliminated by laparoscopic fundoplication. Therefore, endoscopic surveillance should continue.

Abstract
BACKGROUND Although laparoscopic repair of type 3 paraesophageal hernias is safe and results in symptomatic relief, recent data have questioned the anatomic integrity of the laparoscopic approach. The reports document an asymptomatic recurrence rate as high as 42% with radiologic follow-up evaluation for type 3 paraesophageal hernias repaired laparoscopically. This disturbingly high recurrence rate has prompted the addition of an anterior gastropexy to our standard laparoscopic paraesophageal hernia repair. METHODS A prospective series of 28 patients underwent laparoscopic repair of large type 3 hiatal hernias between July 2000 and January 2002 at the Cleveland Clinic Foundation by one surgeon. All the patients underwent reduction of the hernia, sac excision, crural repair, antireflux procedure, and anterior gastropexy. They all had a video esophagram 24 h after surgery, then at 3-, 6-, and 12-month follow-up visits and annually thereafter. Symptomatic outcomes were assessed with a standard questionnaire at each follow-up visit. RESULTS In this study, 21 women and 7 men with a mean age of 67 years (range, 35-82 years) underwent successful laparoscopic paraesophageal hernia repair. The mean operative time was 146 min (range, 101-186 min), and the average blood loss was 71 ml (range, 10-200 ml). One intraoperative complication occurred: A small esophageal mucosal tear occurred during esophageal dissection and was repaired laparoscopically. At 24 h, upper gastrointestinal examination identified no leaks. At this writing, all the patients have undergone video esophagram at a 3-month follow-up visit. All were asymptomatic and all examinations were normal. Of the 28 patients, 27 have undergone follow-up assessment at 6 months. At this writing, all the patients have undergone video esophagram at 3, 6, and 12 months follow up visits. All were asymptomatic and all examinations were normal. Ten patients have completed 2 year follow up barium swallows with no recurrences. CONCLUSIONS With up to 2 years of follow-up evaluation, the addition of an anterior gastropexy to the laparoscopic repair of type 3 hiatal hernias resulted in no recurrences. These encouraging results necessitate further follow-up evaluation to document the long-term effects of anterior gastropexy in reducing postoperative recurrence after laparoscopic repair of paraesophageal hernias.

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
Our objective was to assess the complications of laparoscopic fundoplication in 77 patients older than 70 years of age. The indications for surgery were (1) complications of reflux esophagitis (n = 17), (2) large hiatal hernia (n = 10), (3) asthma and bronchitis (n = 7), (4) the need for other surgery (n = 13), and (5) a patient's desire to discontinue medical treatment that was controlling reflux esophagitis (n = 30). Operative time varied from 34 to 250 minutes (mean [standard deviation], 116 +/- 20). Hospital stay varied from 12 hours to 19 days (mean, 1.2). No patient needed conversion to open operation. Intraoperative complications were observed in 4 patients (5.2%): left pneumothorax in 2, major operative bleeding in 1, and minor spleen lesion in 1. The most common postoperative complications were gas-bloating syndrome and dysphagia. Gastric ulcer was diagnosed in two. Other postoperative complications included acute delirium, acute urinary retention, and acute ischemia of the lower extremity. One patient died of congestive heart failure. It is concluded that laparoscopic fundoplication is an effective procedure for treating geriatric patients with reflux esophagitis and may be performed with low morbidity and mortality rates.

Abstract
There are controversies regarding existence and incidence of short esophagus. The authors reviewed the literature incidence of short esophagus among operated patients due to gastroesophageal reflux disease in the last 3 years. The overall incidence of short esophagus was 1.53%. The proposed risk factors (paraesophageal hernia, Barrett's esophagus, reoperation, esophageal strictures and access route) do have a higher incidence of short esophagus, with the exception of the Barrett's esophagus. Although several biases can be associated with the review, the authors identified the short esophagus incidence in the literature.

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.

BACKGROUND The training of surgeons and residents in laparoscopic surgery has become an important issue. The purpose of this study is to determine if the training of a laparoscopic fellow affects outcomes in patients undergoing laparoscopic splenectomy (LS). METHODS Data were obtained from a prospectively collected database of patients who underwent LS from August 1994 to November 1999. Outcomes of the last 25 cases, performed by fellows under supervision, were compared to 25 cases performed by staff surgeons prior to the introduction of fellows. RESULTS Patient demographics, preoperative platelet count, and splenic size were similar for the two groups. Outcome measures comparing the staff and the fellows group including operative time (151 vs 178 min, p = 0.055), blood loss (214 vs 162 ml, p = 0.40), intraoperative complications (3 vs 2, p = 1.0), need for transfusion (2 vs 3, p = 1.0), conversions (1 vs 0, p = 1.0), length of hospital stay (3.3 vs 2.5 days, p = 0.13), and postoperative complications (1 vs 2, p = 1.0) were similar for the two groups. CONCLUSION When performed by a fellow under supervision, LS has the same outcomes as when the procedure is performed by the teaching staff surgeon.

Abstract
BACKGROUND The objective of this study was to analyze our initial results after laparoscopic repair of large paraesophageal hiatal hernias. METHODS Between October 1997 and May 2000, 37 patients (23 women, 14 men) underwent laparoscopic repair of a large type II (pure paraesophageal) or type III (combined sliding and paraesophageal) hiatal hernia with more than 50% of the stomach herniated into the chest. Median age was 72 years (range 52 to 92 years). Data related to patient demographics, esophageal function, operative techniques, postoperative symptomatology, and complications were analyzed. RESULTS Laparoscopic hernia repair and Nissen fundoplication was possible in 35 of 37 patients (95.0%). Median hospitalization was 4 days (range 2 to 20 days). Intraoperative complications occurred in 6 patients (16.2%) and included pneumothorax in 3 patients, splenic injury in 2, and crural tear in 1. Early postoperative complications occurred in 5 patients (13.5%) and included esophageal leak in 2, severe bloating in 2, and a small bowel obstruction in 1. Two patients died within 30 days (5.4%), 1 from delayed splenic bleeding and 1 from adult respiratory distress syndrome secondary to a recurrent strangulated hiatal hernia. Follow-up was complete in 31 patients (94.0%) and ranged from 3 to 34 months (median 15 months). Twenty-seven patients (87.1%) were improved. Four patients (12.9%) required early postoperative dilatation. Recurrent paraesophageal hiatal hernia occurred in 4 patients (12.9%). Functional results were classified as excellent in 17 patients (54.9%), good in 9 (29.0%), fair in 1 (3.2%), and poor in 4 (12.9%). CONCLUSIONS Laparoscopic repair of large paraesophageal hiatal hernias is a challenging operation associated with significant morbidity and mortality. More experience, longer follow-up, and further refinement of the operative technique is indicated before it can be recommended as the standard approach.

Abstract
OBJECTIVES This study demonstrates the application of time-action analysis to the evaluation of task performance of diagnostic laparoscopy with laparoscopic ultrasonography. METHODS The first 25 diagnostic laparoscopies with laparoscopic ultrasonography performed by a surgical resident were analyzed and compared with the outcomes of these procedures performed by an experienced surgeon. The time, actions, and correctness of task performance were evaluated. Furthermore, outcome correctness and postoperative complications were assessed. RESULTS No postoperative complications occurred. The resident made one wrong diagnosis, for which the cause was detected by peroperative analysis. Additionally, 1% of the subtasks were performed only partially, 4% not at all, and 2% using the wrong technique. The efficiency for most diagnostic tasks remained significantly lower than that of the experienced surgeon (p < 0.001). CONCLUSIONS Time-action analysis can be used to provide detailed insight into the quality and efficiency of learning surgical skills. It enables objective measurement of correctness in task performance as well as time and action efficiency.

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 There is a widespread belief that introduction of the laparoscopic technique in antireflux surgery has led to easier postoperative recovery. To test this hypothesis a prospective randomized clinical trial with blind evaluation was conducted between laparoscopic and open fundoplication. METHODS Sixty patients with gastro-oesophageal reflux disease were randomized to open or laparoscopic 360 degrees fundoplication. The type of operation was unknown to the patient and the evaluating nurses after operation. RESULTS The operating time was longer in the laparoscopy group, median 148 versus 109 min (P < 0.0001). The need for analgesics was less in the laparoscopically operated patients, 33.9 versus 67.5 mg morphine per total hospital stay (P < 0.001). There was no significant difference in postoperative nausea and vomiting. On the first day after operation patients in the laparoscopy group had better respiratory function: forced vital capacity 3.2 versus 2. 2 litres (P = 0.004) and forced expiratory volume 2.6 versus 2.0 litres (P = 0.008). Postoperative hospital stay was shorter in the laparoscopic group, median (range) 3 (2-6) versus 3 (2-10) days (P = 0.021). No difference was found in the duration of sick leave. CONCLUSION Laparoscopic fundoplication was associated with a longer operating time, better respiratory function, less need for analgesics and a shorter hospital stay, while no reduction in the duration of postoperative sick leave was found compared with open surgery.

Abstract
The performance of a laparoscopic inguinal hernia repair requires unique technical and cognitive skills which, until recently, were not routinely taught to general surgeons. The initial experience of three surgeons with laparoscopic hernia repair was audited prospectively to assess the learning curve for the technique. From March 1992 to June 1994, transabdominal preperitoneal (TAP) mesh repair was attempted on 172 consecutive inguinal hernias. Three procedures were converted to traditional repairs. The three independent surgeons that performed the repairs had minimal or no prior clinical experience with the technique in the role as primary surgeon. The hernia repairs were divided into two groups. Group 1 consisted of the first 90 hernia repairs in the series, 30 repairs per surgeon. This group was compared to the subsequent 82 repairs (group 2), approximately 27 repairs per surgeon. Patients were followed up for a median of 31 months. Group 1 had more patients who were hospitalized overnight (37% versus 31%), a greater rate of conversion (2.2% versus 1.2%), a higher complication rate (11.7% versus 0%), a higher recurrence rate (12.2% versus 0%), and a longer delay in the return to full activity (11 weeks versus 8 weeks). Also, overall patient satisfaction with their hernia repair was slightly greater in group 2 (score, 9.0/10 versus 8.2/10). The lack of prior experience with the TAP technique (one surgeon) was associated with a marked increase in the number of conversions (two of three total conversions), complications (four of eight total), and hernia recurrences (8 of 11 total). This study demonstrates that a surgeon's initial experience with laparoscopic herniorrhaphy is associated with an identifiable learning curve. Significant improvements in complication and recurrence rates and overall patient satisfaction can be expected after the initial learning phase. Also, a complete lack of prior experience with laparoscopic herniorrhaphy is associated with a higher rate of conversion and significant increases in complications and hernia recurrences.

Abstract
This study was done to determine the factors contributing to laparoscopic failure (conversion to open surgery or early reoperation) during the learning curve for laparoscopic Nissen fundoplication in a 228-bed nonteaching community hospital. Data were gathered prospectively for the first 100 consecutive patients booked for elective laparoscopic Nissen fundoplication by the four general surgeons at the hospital. All complications were recorded contemporaneously, and particular note was taken of the factors surrounding conversion to open surgery and reoperation within 100 days of surgery. There were no deaths. The conversion rate was 20% and the early reoperation rate 6%. There were two late recurrences. The average operative time was 117 minutes and the average length of stay 1.8 days; 37 operations were performed on outpatients. The laparoscopic failure rate was 26% (18/68) during a surgeon's first 20 operations and 11% (3/28) thereafter (P < 0.09); the corresponding conversion rates were 22% and 4% (P < 0.05). During a surgeon's first 20 operations, the laparoscopic failure rate rose from 21% (12/57) to 55% (6/11) (P < 0.04) if a second surgeon did not assist. After 20 operations, this difference lost its significance. Intrathoracic herniation of the stomach was found preoperatively in 11 (44%) of 25 operations followed by laparoscopic failure and (8%) 6 of 75 without (P < 0.0002). Laparoscopic failure had no correlation with patient age, sex, ASA classification, duration of symptoms, or referring physician's specialty. The individual learning curve for laparoscopic Nissen fundoplication requires about 20 operations to surmount. Factors leading to laparoscopic failure during the learning curve are the surgeon's inexperience, absence of experienced help, and the presence of intrathoracic herniation.

Abstract
BACKGROUND Between September 1985 and July 1990, the first 100 consecutive patients (50 female and 50 male) undergoing primary uncut Collis-Nissen fundoplication performed by one surgeon were reviewed. METHODS Median age was 62 years and ranged from 19 to 89 years. Indications for repair included gastroesophageal reflux in 56 patients, obstructive symptoms in 34, and a combination of both in 10. An upper gastrointestinal endoscopy was performed in 99 patients; all were abnormal. Esophagitis was documented in 53 patients, large diaphragmatic hernia in 36, stenosis in 18, "Cameron's erosions" in 17, Barrett's disease in 13, and other findings in 9 patients. An abnormal upper gastrointestinal series was demonstrated in 96 of 97 patients evaluated. Motility studies were performed in 95 patients, and 11 had abnormal peristalsis. All procedures were performed through a left thoracotomy. RESULTS Complications occurred in 23 patients and included respiratory failure in 6, atrial fibrillation in 3, atelectasis in 3, pneumonia in 2, myocardial infarction in 2, and chylothorax, severe dysphagia, early breakdown of repair, cardiac tamponade, hematuria, spinal headache, and intraoperative perforation by dilator in 1 each. There were 2 postoperative deaths, both cardiac in origin. Median hospitalization was 8 days (range, 6 to 76 days). The first 25 patients had 10 complications (40%) and 2 deaths (8%). The remaining 75 patients had 13 complications (17%) and no deaths (mortality, p = 0.06; morbidity, p = 0.03). Follow-up was complete in all patients for a median of 100 months (range, 3 to 138 months). Eighty-six of the 98 operative survivors are currently alive. At last follow-up, excellent functional results were observed in 58 patients (59%), good in 24 (25%), fair in 8 (8%), poor in 7 (7%), and unknown in 1 (1%). CONCLUSION We conclude that the uncut Collis-Nissen fundoplication provides good to excellent long-term results in 84% of patients. Operative mortality and morbidity is acceptable but is associated with a learning curve.
