Abstract
Locoregional esophageal cancer is currently treated with induction chemoradiotherapy, followed by esophagectomy with reconstruction, using a gastric conduit. In cases of conduit failure, patients are temporized with a cervical esophagostomy and enteral nutrition until gastrointestinal continuity can be established. At our institution, we favor reconstruction, using a colon interposition with a 'supercharged' accessory vascular pedicle. Consequently, we sought to examine our technique and outcomes for esophageal reconstruction, using this approach. We performed a retrospective review of all patients who underwent esophagectomy at our center between 2008 and 2018. We identified those patients who had a failed gastric conduit and underwent secondary reconstruction. Patient demographics, perioperative details, and clinical outcomes were analyzed after our clinical care pathway was used to manage and prepare patients for a second major reconstructive surgery. Three hundred and eighty eight patients underwent esophagectomy and reconstruction with a gastric conduit. Seven patients (1.8%) suffered gastric conduit loss and underwent a secondary reconstruction using a colon interposition with a 'supercharged' vascular pedicle. Mean age was 70.1 (±7.3) years, and six patients were male. The transverse colon was used in four cases (57.1%), left colon in two cases (28.6%), and right colon in one case (14.3%). There were no deaths or loss of the colon interposition at follow-up. Three patients (42.9%) developed an anastomotic leak, which resolved with conservative management. All patients had resumption of oral intake within 30 days. Utilizing a 'supercharging' technique for colon interposition may improve the perfusion to the organ and may decrease morbidity. Secondary reconstruction should occur when the patient's oncologic, physiologic, and psychosocial condition is optimized. Our outcomes and preoperative strategies may provide guidance for those centers treating this complicated patient population.

Abstract
Trimodal therapy consisting of neoadjuvant chemoradiation followed by esophagectomy has become the standard of care in North America for locally advanced esophageal cancer. While cisplatin/5-fluorouracil has been a common concurrent chemotherapy regimen since the 1980s, its utilization has declined in recent years as the Chemoradiotherapy for Oesophageal Cancer Followed by Surgery Study (CROSS) trial regimen of carboplatin/paclitaxel has become widely adopted. The efficacy of the CROSS regimen compared to alternate chemotherapy choices, however, has rarely been evaluated when each is used as a component of a trimodal treatment approach. The aim of this study is to report our institutional experience with these two concurrent chemotherapy regimens at a specialized esophageal cancer center.We performed an Institutional Review Board-approved retrospective review of a prospectively maintained institutional foregut registry from a single National Cancer Institute-designated cancer center. Esophageal cancer patients who completed trimodal therapy with a chemotherapy regimen of either carboplatin/paclitaxel or cisplatin/5-fluorouracil were identified and divided into groups based on their chemotherapy regimens. Multivariable logistic regression was used to analyze pathologic complete response rates, while the Kaplan-Meier and Cox proportional hazards models were utilized to evaluate recurrence-free and overall survival. Analytical models were adjusted for age, clinical stage, radiation dose, histologic subtype (adenocarcinoma vs. squamous cell carcinoma), and time interval from completion of neoadjuvant therapy to surgery.One hundred and forty-two patients treated between January of 2000 and July of 2015 were identified as meeting inclusion criteria. Of this group, 87 had received the CROSS regimen of carboplatin/paclitaxel, while 55 had completed cisplatin/5-fluorouracil. Multivariable analysis demonstrated that the cisplatin/5-fluorouracil.group had an increased odds of pathologic complete response (odds ratio = 2.68, 95% confidence interval, P = 0.032), as well as significantly improved recurrence-free survival (hazard ratio = 0.39, 95% confidence interval 0.21-0.73, P = 0.003) and overall survival (hazard ratio = 0.46, 95% confidence interval 0.24-0.87, P = 0.016), compared to the carboplatin/paclitaxel group.Concurrent chemotherapy with cisplatin/5-fluorouracil in locally advanced esophageal cancer is associated with higher rates of pathologic complete response and improved recurrence-free and overall survival compared to the CROSS regimen of carboplatin/paclitaxel. This suggests that, for select patients, alternate neoadjuvant chemotherapy approaches, such as cisplatin/5-fluorouracil, merit reconsideration as potential primary treatment choices in the management of this highly morbid disease.

Abstract
Trimodality therapy for resectable esophageal and gastroesophageal junction cancers utilizing preoperative radiotherapy with concurrent carboplatin and paclitaxel-based chemotherapy is being increasingly utilized secondary to the results of the phase III CROSS trial. However, there is a paucity of reports of this regimen as a component of chemoradiotherapy in North America. We aim to report on our clinical experience using a modified CROSS regimen with higher radiotherapy doses. Patients with advanced (cT2-cT4 or node positive) esophageal or gastroesophageal junction carcinoma who received preoperative carboplatin/paclitaxel-based chemoradiotherapy with radiation doses of greater than 41.4 Gray (Gy) followed by esophagectomy were identified from an institutional database. Patient, imaging, treatment, and tumor response characteristics were analyzed. Twenty-four patients were analyzed. All but one tumor had adenocarcinoma histology. The median radiation dose was 50.4 Gy. Pathologic complete response was achieved in 29% of patients, with all receiving 50.4 Gy. Three early postoperative deaths were seen, due in part to acute respiratory distress syndrome and all three patients received 50-50.4 Gy. With a median follow-up of 9.4 months (23 days-2 years), median survival was 24 months. Trimodality therapy utilizing concurrent carboplatin/paclitaxel with North American radiotherapy doses appeared to have similar pathologic complete response rates compared with the CROSS trial, but may be associated with higher toxicity. Although the sample size is small and further follow-up is necessary, radiation doses greater than 41.4 Gy may not be warranted secondary to a potentially increased risk of severe radiation-induced acute lung injury.

Abstract
This study aimed to determine the impact of preoperative staging on the treatment of clinical T2N0 (cT2N0) esophageal cancer patients undergoing esophagectomy. We reviewed a retrospective cohort of 27 patients treated at a single institution between 1999 and 2011. Clinical staging was performed with computed tomography, positron emission tomography, and endoscopic ultrasound. Patients were separated into two groups: neoadjuvant therapy followed by surgery (NEOSURG) and surgery alone (SURG). There were 11 patients (41%) in the NEOSURG group and 16 patients (59%) in the SURG group. In the NEOSURG group, three of 11 patients (27%) had a pathological complete response and eight (73%) were partial or nonresponders after neoadjuvant therapy. In the SURG group, nine of 16 patients (56%) were understaged, 6 (38%) were overstaged, and 1 (6%) was correctly staged. In the entire cohort, despite being clinically node negative, 14 of 27 patients (52%) had node-positive disease (5/11 [45%] in the NEOSURG group, and 9/16 [56%] in the SURG group). Overall survival rate was not statistically significant between the two groups (P = 0.96). Many cT2N0 patients are clinically understaged and show no preoperative evidence of node-positive disease. Consequently, neoadjuvant therapy may have a beneficial role in treatment.

Abstract
BACKGROUND In developed countries, hepatitis E is a porcine zoonosis caused by hepatitis E virus (HEV) genotype 3. In developing countries, hepatitis E is mainly caused by genotype 1, and causes increased mortality in patients with pre-existing chronic liver disease (CLD). AIM To determine the role of HEV in patients with decompensated CLD. METHODS Prospective HEV testing of 343 patients with decompensated CLD at three UK centres and Toulouse France, with follow-up for 6 months or death. IgG seroprevalence was compared with 911 controls. RESULTS 11/343 patients (3.2%) had acute hepatitis E infection, and three died. There were no differences in mortality (27% vs. 26%, OR 1.1, 95% CI 0.28-4.1), age (P = 0.9), bilirubin (P = 0.5), alanine aminotransferase (P = 0.06) albumin (P = 0.5) or international normalised ratio (P = 0.6) in patients with and without hepatitis E infection. Five cases were polymerase chain reaction (PCR) positive (genotype 3). Hepatitis E was more common in Toulouse (7.9%) compared to the UK cohort (1.2%, P = 0.003). HEV IgG seroprevalence was higher in Toulouse (OR 17, 95% CI 9.2-30) and Truro (OR 2.5, 95% CI 1.4-4.6) than in Glasgow, but lower in cases, compared to controls (OR 0.59, 95% CI 0.41-0.86). CONCLUSIONS Hepatitis E occurs in a minority of patients with decompensated chronic liver disease. The mortality is no different to the mortality in patients without hepatitis E infection. The diagnosis can only be established by a combination of serology and PCR, the yield and utility of which vary by geographical location.

METHODS Retrospective review of data of 106 cases of autochthonous hepatitis E (acute n = 105, chronic n = 1). RESULTS Eight (7.5%) cases presented with neurological syndromes, which included brachial neuritis, Guillain-Barré syndrome, peripheral neuropathy, neuromyopathy and vestibular neuritis. Patients with neurological syndromes were younger (median age 40 years, range 34-92 years, P = 0.048) and had a more modest transaminitis (median ALT 471 IU/L, P = 0.015) compared to cases without neurological symptoms [median age 64 years (range 18-88 years), median ALT 1135 IU/L]. One patient presented with a cardiac arrhythmia,twelve patients (11.3%) presented with thrombocytopenia, fourteen (13.2%) with lymphocytosis and eight (7.5%) with a lymphopenia, none of which had any clinical consequence. Serum electrophoresis was performed in 65 patients at presentation, of whom 17 (26%) had a monoclonal gammopathy of uncertain significance. Two cases developed haematological malignancies, acute myeloid leukaemia and duodenal plasmacytoma, 18 and 36 months after presenting with acute hepatitis E infection. CONCLUSIONS A range of extra-hepatic manifestations can occur with hepatitis E. Neurological and haematological features of hepatitis E infection are relatively frequent in this UK cohort, and result in significant morbidity which warrants further study.

Abstract
A novel hepatitis virus was long suspected as the cause of outbreaks of unexplained hepatitis with high maternal mortality in Asia. An outbreak of unexplained hepatitis in a Soviet military camp in Afghanistan led one investigator to ingest a pooled fecal extract from affected service personnel. This resulted in the discovery of the hepatitis E virus (HEV) in 1983. Subsequent studies showed that HEV was endemic in large parts of the developing world. Its incidence in industrialized nations was initially attributed to travel-related exposure. For many years after the discovery of HEV, it was considered a "new" virus, and of no relevance to developed countries. This perceived wisdom has proven to be hopelessly inaccurate. Human infections with HEV are not "new," and are of considerable global importance, including in developed countries.

Abstract
BACKGROUND Abnormal liver blood tests are common in Epstein-Barr virus (EBV) infection, but symptomatic hepatitis is rare. The demographics, clinical features and outcome of EBV hepatitis are incompletely understood, particularly in the elderly people. AIM To identify the demographics, presenting features and natural history of EBV hepatitis. METHODS Retrospective review of 1995 consecutive patients attending the jaundice hotline clinic over a 13-year period. Data collected included demographic information, presenting features, clinical and laboratory parameters, radiology imaging and clinical outcome. RESULTS Seventeen of 1995 (0.85%) had EBV hepatitis. The median age was 40 years (range 18-68 years). Ten of 17 (59%) patients were aged >30 years, and seven of 17 (41%) patients were aged ≥60 years. Fifteen of 17 (88%) patients presented with clinical/biochemical evidence of jaundice. Seventeen of 17 (100%) patients had a serum lymphocytosis at presentation. 2/17 (12%) patients with EBV hepatitis presented with the classical features of infectious mononucleosis (fever, sore throat and lymphadenopathy). Splenomegaly was present in 15/17 (88%) of patients. Symptoms lasted for a median 8 weeks (range 1-12 weeks). Three of 17 (18%) patients required a brief hospital admission. CONCLUSIONS In patients presenting with jaundice/hepatitis, EBV hepatitis is an uncommon diagnosis and causes a self-limiting hepatitis. The diagnosis is suggested by the presence of a lymphocytosis and/or splenomegaly. The majority of patients do not have infectious mononucleosis. Compared with infectious mononucleosis, EBV hepatitis affects an older age group, with nearly half of patients being aged more than 60 years. The diagnosis should be considered in all patients with unexplained hepatitis irrespective of their age.

Abstract
Proper anastomotic healing is dependent upon many factors including adequate blood flow to healing tissue. The aim of this study was to investigate the impact of vascular endothelial growth factor (VEGF(165)) transfection on anastomotic healing in an ischemic gastrointestinal anastomosis model. Utilizing an established opossum model of esophagogastrectomy followed by esophageal-gastric anastomosis, the gastric fundus was transfected with recombinant human vascular endothelial growth factor via direct injection of a plasmid-based nonviral delivery system. Twenty-nine animals were divided into three groups: two concentrations of VEGF and a control group. Outcomes included VEGF mRNA transcript levels, neovascularization, tissue blood flow, and anastomotic bursting pressure. To determine whether local injection resulted in a systemic effect, distant tissues were evaluated for VEGF transcript levels. Successful gene transfection was demonstrated by quantitative polymerase chain reaction analysis of anastomotic tissue, with significantly higher VEGF mRNA expression in treated animals compared to controls. At the gastric side of the anastomosis, there was significantly increased neovascularization, blood flow, and bursting pressure in experimental animals compared to controls. There were no differences in outcome measures between low- and high-dose VEGF groups; however, the high-dose group demonstrated increased VEGF mRNA expression across the anastomosis. VEGF production was not increased at distant sites in treated animals. In this animal model, VEGF gene therapy increased VEGF transcription at a healing gastrointestinal anastomosis without systemic VEGF upregulation. This treatment led to improved healing and strength of the acutely ischemic anastomosis. These findings suggest that VEGF gene therapy has the potential to reduce anastomotic morbidity and improve surgical outcomes in a wide array of patients.

Abstract
OBJECTIVE To determine the strength of evidence supporting the battlefield use of Continual Peripheral Nerve Blocks (CPNBs). METHODS Publication review identifying 380 potentially relevant papers. RESULTS CPNBs have been well trialled and are used routinely in civilian hospitals. The procedure is not without acute and chronic complications related to agents used, catheters themselves and infection risks. These techniques are being used increasingly in military field hospitals to manage pain, however research concerning their use on the battlefield is limited and further trials are required to confidently conclude efficacy. CONCLUSION CPNBs are just one component within military medicine of a rapidly evolving polymodal system of pain management. Common combat wounds, namely traumatic amputations, are compatible with this technique, however current evidence concerning their battlefield use is limited. Extensive UK military trials are ongoing and the results of which are expected to clarify questions regarding complication rate and efficacy.

Abstract
Controversy exists regarding optimal treatment practices for esophageal cancer. Esophagectomy has received focus as one of the index procedures for both hospital and surgical quality despite a relative paucity of controlled trials to define best practices. A survey was created to determine the degree of heterogeneity in the treatment of esophageal cancer among a diverse group of surgeons and to use high-volume (HV) (>/=15 cases/year) and low-volume (LV) (<15 cases/year) designations to discern specific differences in the management of esophageal cancer from the surgeon's perspective. Based on society rosters, surgeons (n = 4000) in the USA and 15 countries were contacted via mail and queried regarding their treatment practices for esophageal cancer using a 50-item survey instrument addressing demographics, utilization of neoadjuvant chemoradiotherapy, and choice of surgical approach for esophageal resection and palliation. There were 618 esophageal surgeons among respondents (n = 1447), of which 77 (12.5%) were considered HV. The majority of HV surgeons (87%) practiced in an academic setting and had cardiothoracic training, while most LV surgeons were general surgeons in private practice (52.3%). Both HV and LV surgeons favored the hand-sewn cervical anastomosis and the stomach conduit. Minimally invasive esophagectomy is performed more frequently by HV surgeons when compared with LV surgeons (P = 0.045). Most HV surgeons use neoadjuvant therapy for patients with nodal involvement, while LV surgeons are more likely to leave the decision to the oncologist. With a few notable exceptions, substantial heterogeneity exists among surgeons' management strategies for esophageal cancer, particularly when grouped and analyzed by case volume. These results highlight the need for controlled trials to determine best practices in the treatment of this complex patient population.

Abstract
The aim of this study is to report assemblage of a large multi-institutional international database of esophageal cancer patients, patient and tumor characteristics, and survival of patients undergoing esophagectomy alone and its correlates. Forty-eight institutions were approached and agreed to participate in a worldwide esophageal cancer collaboration (WECC), and 13 (Asia, 2; Europe, 2; North America, 9) submitted data as of July 1, 2007. These were used to construct a de-identified database of 7884 esophageal cancer patients who underwent esophagectomy. Four thousand six hundred and twenty-seven esophagectomy patients had no induction or adjuvant therapy. Mean age was 62 +/- 11 years, 77% were men, and 33% were Asian. Mean tumor length was 3.3 +/- 2.5 cm, and esophageal location was upper in 4.1%, middle in 27%, and lower in 69%. Histopathologic cell type was adenocarcinoma in 60% and squamous cell in 40%. Histologic grade was G1 in 32%, G2 in 33%, G3 in 35%, and G4 in 0.18%. pT classification was pTis in 7.3%, pT1 in 23%, pT2 in 16%, pT3 in 51%, and pT4 in 3.3%. pN classification was pN0 in 56% and pN1 in 44%. The number of lymph nodes positive for cancer was 1 in 12%, 2 in 8%, 3 in 5%, and >3 in 18%. Resection was R0 in 87%, R1 in 11%, and R2 in 3%. Overall survival was 78, 42, and 31% at 1, 5, and 10 years, respectively. Unlike single-institution studies, in this worldwide collaboration, survival progressively decreases and is distinctively stratified by all variables except region of the world. A worldwide esophageal cancer database has been assembled that overcomes problems of rarity of this cancer. It reveals that survival progressively (monotonically) decreased and was distinctively stratified by all variables except region of the world. Thus, it forms the basis for data-driven esophageal cancer staging. More centers are needed and encouraged to join WECC.

Abstract
Evidence suggests that patients with psychiatric illnesses may be more likely to experience a delay in diagnosis of coexisting cancer. The association between psychiatric illness and timely diagnosis and survival in patients with esophageal cancer has not been studied. The specific aim of this retrospective cohort study was to determine the impact of coexisting psychiatric illness on time to diagnosis, disease stage and survival in patients with esophageal cancer. All patients with a diagnosis of esophageal cancer between 1989 and 2003 at the Portland Veteran's Administration hospital were identified by ICD-9 code. One hundred and sixty patients were identified: 52 patients had one or more DSM-IV diagnoses, and 108 patients had no DSM-IV diagnosis. Electronic charts were reviewed beginning from the first recorded encounter for all patients and clinical and demographic data were collected. The association between psychiatric illness and time to diagnosis of esophageal cancer and survival was studied using Cox proportional hazard models. Groups were similar in age, ethnicity, body mass index, and history of tobacco and alcohol use. Psychiatric illness was associated with delayed diagnosis (median time from alarm symptoms to diagnosis 90 days vs. 35 days in patients with and without psychiatric illness, respectively, P < 0.001) and the presence of advanced disease at the time of diagnosis (37% vs. 18% of patients with and without psychiatric illness, respectively, P= 0.009). In multivariate analysis, psychiatric illness and depression were independent predictors for delayed diagnosis (hazard ratios 0.605 and 0.622, respectively, hazard ratio < 1 indicating longer time to diagnosis). Dementia was an independent risk factor for worse survival (hazard ratio 2.984). Finally, psychiatric illness was associated with a decreased likelihood of receiving surgical therapy. Psychiatric illness is a risk factor for delayed diagnosis, a diagnosis of advanced cancer, and a lower likelihood of receiving surgical therapy in patients with esophageal cancer. Dementia is associated with worse survival in these patients. These findings emphasize the importance of prompt evaluation of foregut symptoms in patients with psychiatric illness.

Abstract
BACKGROUND For patients whose symptoms develop after Nissen fundoplication, the precise mechanism of anatomic failure can be difficult to determine. The authors have previously reported the endosonographic hallmarks defining an intact Nissen fundoplication in swine and the known causes of failure. The current clinical trial tested the hypothesis that a defined set of endosonographic criteria can be applied to determine fundoplication integrity in humans. METHODS The study enrolled seven symptomatic and nine asymptomatic subjects at a mean of 6 years (range, 1-30 years) after Nissen fundoplication. A validated gastroesophageal reflux disease (GERD)-specific questionnaire and medication history were completed. Before endoscopic ultrasound (EUS), all the patients underwent complete conventional testing (upper endoscopy, esophagram, manometry, 24-h pH). A diagnosis was rendered on the basis of combined test results. Then EUS was performed by an observer blinded to symptoms, medication use, and conventional testing diagnoses. Because EUS and esophagogastroduodenoscopy (EGD) are uniformly performed in combination, the EUS diagnosis was rendered on the basis of previously established criteria combined with the EGD interpretation. The diagnoses then were compared to examine the contribution of EUS in this setting. RESULTS The technique and defined criteria were easily applied to all subjects. All symptomatic patients had heartburn and were taking proton pump inhibitors (PPI). No asymptomatic patients were taking PPI. All diagnoses established with combined conventional testing were detected on EUS with upper endoscopy. Additionally, EUS resolved the etiology of a low lower esophageal sphincter pressure in two symptomatic patients and detected the additional diagnoses of slippage in two subjects. Among asymptomatic subjects, EUS identified additional diagnoses in two subjects considered to be normal by conventional testing methods. CONCLUSION According to the findings, EUS is a feasible method for evaluating post-Nissen fundoplication hiatal anatomic relationships. The combination of EUS and EGD allows the mechanism of failure to be detected in patients presenting with postoperative symptoms after Nissen fundoplication.

Abstract
BACKGROUND The objectives of this study were to determine the national proportions and mortality rate for bile duct injuries resulting from laparoscopic cholecystectomy (LC) that required operative reconstruction for repair over a 10-year period and to investigate the major factors associated with the mortality rate in this group of patients. METHODS Using the Nationwide Inpatient Sample (NIS) of >7 million patient records per year, we extracted and analyzed data for LC during the years 1990-2000. Procedures that involved biliary reconstructions performed as part of another primary procedure were excluded. Using the Statistical Package for the Social Sciences (SPSS), we used procedure-specific codes that enabled us to calculate national estimates for LC for the time period under review. We then calculated biliary reconstruction procedures that occurred after LC for this cohort of patients. Finally, we analyzed in-hospital mortality, as well as the patient, institutional, and outcome characteristics associated with biliary reconstructions. RESULTS The percentage of cholecystectomies performed laparoscopically has increased over the years for which data are available (from 52% in 1991 to 75% in 2000). Despite this increase, the mortality rate for this group of patients has remained consistently low over the study period (mean, 0.45%; range 0.33-0.58%). Within this group of patients, the average rate of bile duct injuries requiring operative repair was 0.15% for the years under study. The reconstruction rates ranged from 0.25% in 1992 to 0.09% in 1999. For 2000, the most recent year for which data are available, biliary reconstruction was performed in 0.10% of all patients who underwent LC. The average mortality rate for patients undergoing biliary reconstruction for the years 1991 to 2000 was 4.5%. After multivariate analysis, age, African American ethnicity, type of admission, source of admission, and hospital location, and teaching status were all found to correlate significantly with death after-biliary reconstruction. CONCLUSIONS These data show an increase in the percentage of cholecystectomies performed laparoscopically over the years under study and an associated low mortality rate. In contrast, although the number of bile duct injuries appears to be decreasing, these procedures continue to be associated with a significant mortality rate.

Abstract
BACKGROUND Efforts to ablate Barrett's epithelium have met with mixed results. We report the long-term follow-up evaluation of the preliminary cohort of patients who underwent thermal ablation of Barrett's epithelium with the potassium-titanyl-phosphate (KTP) laser after anti-reflux surgery. METHODS Nine patients with intestinal metaplasia (IM) of the esophagus underwent fundoplication (7 laparoscopic Nissen, 1 laparoscopic Toupet, 1 open Nissen) between May 1993 and October 1994. Three patients had an IM less than 3 cm long (33%). One year after the operation, all the patients were symptom free, had discontinued medications, and had a normal 24-h pH study. From June 1995 to February 1996, these patients underwent a median of two (range, 1-5) endoscopic procedures with directed mucosal ablation using the KTP laser. A comparative cohort of 21 patients (IM length, <3cm; 38%) treated during the same period with fundoplication alone served as a control. The patients were followed prospectively with annual or biennial endoscopy and biopsy. All the patients were contacted by mail, telephone, or clinic visit annually to determine symptomatic and quality-of-life outcome of antireflux surgery. RESULTS The mean follow-up period was 6.8 years (range, 6-7.5 years). At this writing, the study patients are alive and well. Eight of the patients have experienced histologic loss of IM (89%) according to their last biopsy result. One patient has had regression of low-grade dysplasia to IM. The patients treated with fundoplication alone had a mean follow-up period of 5.6 years (range, 4.7-7.2 years). On the basis of the last biopsy result, 7 of 21 patients (33%) had no evidence of IM. CONCLUSIONS A program of tailored antireflux surgery followed by thermal mucosal ablation causes a loss of IM in a majority of patients with Barrett's esophagus. This may represent a significant improvement in histologic outcome over that of treatment with fundoplication alone (p = 0.007 Fisher's exact test).

Abstract
BACKGROUND It has been reported that the laparoscopic repair of paraesophageal hernias is associated with higher complication and recurrence rates than the open methods of repair. METHODS We identified 136 consecutive patients who underwent laparoscopic repair of a paraesophageal hernia between 1993 and 1999. Patient demographics and symptom scores for regurgitation, heartburn, chest pain, and dysphagia at presentation and at last follow-up were recorded (0 = none, 1 = mild, 2 = moderate, 3 = severe). The operative records were reviewed, and early and late complications were noted. Only patients with a follow-up of >1 were included in the analysis. RESULTS The median age was 64 years, and there was a female preponderance (1.8:1). Most patients had some medical comorbidity; the American Society of Anesthesiologists (ASA) scores were <2 in eight patients and ?2 in 117 patients. Three laparoscopic operations were converted to open procedures. There were nine intraoperative complications, five early complications, and three related deaths (morbidity and mortality rates of 10.2% and 2.2%, respectively). Follow-up data were available for 83 patients (66%), and the mean follow-up time was 40 months (range, 12-82). The percentage of patients experiencing chest pain, dysphagia, heartburn, and regurgitation in the moderate to severe range dropped from a range of 34-47% to 5-7% (p <0.05). Three patients underwent repeat laparoscopic repair for symptomatic recurrence. CONCLUSION The laparoscopic repair of paraesophageal hernias provides excellent long-term symptomatic relief in the majority of patients and has a low rate of symptomatic recurrence. The complication and death rates may be related in part to the higher incidence of comorbidities in this somewhat elderly patient population.

Abstract
BACKGROUND Historically, splenectomy has been an accepted procedure in the management of immune thrombocytopenic purpura (ITP). However, it is also true that the response to splenectomy in patients with ITP seems to be unpredictable. Therefore, the purpose of this study was to identify clinical variables that might predict a favorable response to splenectomy in patients with ITP. METHODS Data were collected retrospectively for 40 adult patients with ITP who underwent laparoscopic (LS) and open (OS) splenectomy at Emory University Hospital between 1992 and 1999. Demographics and outcomes were recorded. Age, sex, disease duration, comorbidities (ASA > 2), previous response to steroids and/or other medications, and preoperative platelet count were analyzed by univariate (t-test, Fisher's exact test) and multivariate statistical methods. RESULTS Of the 20 patients in each group, improved platelet counts were noted in 18 patients (90%) in the LS group and 20 patients (100%) in the OS group. Follow-up (16 +/- 3 months) was obtained in 19 LS patients (95%) and 16 OS patients (80%), with 84% and 87.5% sustained response rates, respectively. After univariate analysis, two variables (age and disease duration) were found to be significantly related to the outcome of splenectomy (p <lt; 0.01). However, after multiple logistic regression analysis, only disease duration (relative risk = 1.083; CI, 1.004-1.167) was an independent prognostic factor for a sustained response to splenectomy. CONCLUSION These results suggest that the response to splenectomy (laparoscopic and open) in patients with ITP cannot be adequately predicted on the basis of presplenectomy clinical variables. However, disease duration and patient age should be taken into consideration when selecting patients for splenectomy.

Abstract
BACKGROUND Atypical manifestations of gastro-oesophageal reflux (GOR) include asthma, chest pain, cough and hoarseness. The effectiveness of antireflux surgery for these symptoms is uncertain. The present study compared symptomatic response rates for typical and atypical GOR symptoms after fundoplication. METHODS Between October 1991 and January 1998, 324 patients underwent laparoscopic fundoplication at Emory University Hospital and returned postoperative questionnaires. Severity of typical (heartburn) and atypical (asthma, chest pain, cough and hoarseness) GOR symptoms was reported by patients on a 0-4 scale before surgery, and at 6 and 52 weeks after operation. Patients were stratified based on preoperative symptoms into three groups: group 1 (severe heartburn/minimal atypical symptoms), group 2 (severe heartburn/severe atypical symptoms) and group 3 (minimal heartburn/severe atypical symptoms). RESULTS In group 1 (n = 173) heartburn improved in 99 per cent and resolved in 87 per cent. In group 2 (n = 95) heartburn improved in 95 per cent and resolved in 76 per cent, and atypical symptoms improved in 94 per cent and resolved in 42 per cent. In group 3 (n = 56) atypical symptoms improved in 93 per cent and resolved in 48 per cent. Although all symptoms were improved by fundoplication, resolution was more likely for heartburn than for atypical symptoms. CONCLUSION Atypical symptoms of GOR are improved by fundoplication, but symptom resolution occurs in fewer than 50 per cent of patients.

Abstract
The effects of distinct classes of peroxisome proliferator-activated receptor gamma (PPARgamma) ligands on myogenesis and MyoD gene expression were examined in mouse skeletal muscle C2C12 myoblasts. Treatment of C2C12 cells with the PPARgamma ligand, 15-deoxy-Delta12,14-prostaglandin J2 (15d-PGJ2), repressed morphologically defined myogenesis and reduced endogenous mRNA levels of the myogenic differentiation markers MyoD, myogenin, and alpha-actin. In contrast, two synthetic PPARgamma ligands, L-805645 and ciglitazone, exhibited no effects. In transient transfection assays, 15d-PGJ2 specifically inhibited the expression of a MyoD promoter-luciferase reporter gene (MyoDLuc) in a cell type- and promoter-specific manner, indicating that 15d-PGJ2 functions in part by repressing MyoD gene transcription. The inhibition of MyoD gene expression by 15d-PGJ2 is mediated by the distal region of the MyoD gene promoter. PPARgamma on its own also inhibited MyoDLuc expression and further augmented the 15d-PGJ2 response. In contrast, L-805645 and ciglitazone did not inhibit MyoDLuc expression on their own but did so in the presence of ectopically expressed PPARgamma. Interestingly, a transdominant inhibitor of PPARgamma (hPPARgamma2Delta500) had no effect on the 15d-PGJ2-dependent repression of MyoDLuc expression but overcame L-805645/PPARgamma-dependent repression. Finally, saturating concentrations of L-805645, which did not affect myogenesis, failed to ablate 15d-PGJ2-mediated repression of the myogenic program. Thus, distinct PPARgamma ligands may repress MyoD gene expression through PPARgamma-dependent and -independent pathways, and 15d-PGJ2 can inhibit the myogenic program independent of its cognate receptor, PPARgamma.

Abstract
OBJECTIVE To determine whether surgical residency training has influenced the occurrence of common bile duct injuries during laparoscopic cholecystectomy, and to asses the anatomic and technical details of bile duct injuries from the practices of surgeons trained in laparoscopic cholecystectomy after residency versus surgeons trained in laparoscopic cholecystectomy during residency. SUMMARY BACKGROUND DATA Shortly after the introduction of laparoscopic cholecystectomy, the rate of injury to the common bile duct increased to 0.5%, and injuries were more commonly reported early in each surgeon's experience. It is not known whether learning laparoscopic cholecystectomy during surgery residency influences this pattern. METHODS An anonymous questionnaire was mailed to 3,657 surgeons across the United States who completed an Accreditation Council for Graduate Medical Education (ACGME)-approved residency between 1980 and 1990 (group A) or 1992 and 1998 (group B). All surgeons in group A learned laparoscopic cholecystectomy after residency, and all those in group B learned laparoscopic cholecystectomy during residency. Information obtained included practice description, number of laparoscopic cholecystectomies completed since residency, postgraduate training in laparoscopy, and annual volume of laparoscopic cholecystectomy in the surgeon's hospital. In addition, technical details queried included the completion of a cholangiogram, the interval between injury and identification, the method of repair, and the site of definitive treatment. The primary endpoint was the occurrence of a major bile duct injury during laparoscopic cholecystectomy (bile leaks without a major bile duct injury were not tabulated). RESULTS Forty-five percent (n = 1,661) of the questionnaires were completed and returned. Mean practice experience was 13.6 years for group A and 5.4 years for group B. At least one injury occurrence was reported by 422 surgeons (37.6%) in group A and 143 surgeons (26.5%) in group B. Forty percent of the injuries in group A occurred during the first 50 cases compared with 22% in group B. Thirty percent of bile duct injuries in group A and 32.9% of all injuries in group B occurred after a surgeon had performed more than 200 laparoscopic cholecystectomies. Independent of the number of laparoscopic cholecystectomies completed since residency, group A surgeons were 39% more likely to report one or more biliary injuries and 58% more likely to report two or more injuries than their counterparts in group B. Bile duct injuries were more likely to be discovered during surgery if a cholangiogram was completed than if cholangiography was omitted (80.9% vs. 45.1%). Sixty-four percent of all major bile duct injuries required biliary reconstruction, and most injuries were definitively treated at the hospital where the injury occurred. Only 14.7% of injuries were referred to another center for repair. CONCLUSIONS Accepting that the survey bias underestimates the true frequency of bile duct injuries, residency training decreases the likelihood of injuring a bile duct, but only by decreasing the frequency of early "learning curve" injuries. If one accepts a liberal definition of the learning curve (200 cases), it appears that at least one third of injuries are not related to inexperience but may reflect fundamental errors in the technique of laparoscopic cholecystectomy as practiced by a broad population of surgeons in the United States. Intraoperative cholangiography is helpful for intraoperative discovery of injuries when they occur. Most injuries are repaired in the hospital where they occur and are not universally referred to tertiary care centers.

Abstract
BACKGROUND Barrett's esophagus affects 5-10% of patients with gastroesophageal reflux disease (GERD) and is associated with a 40-fold increased risk of malignant transformation. Ablative therapies may lead to esophageal perforation or stricture formation if applied too liberally and residual glandular tissue and persistent cancer risk if utilized too sparingly. METHODS Ten pigs underwent gastrotomy. Mucosa below the gastroesophageal (GE) junction was elevated by saline injections, circumferentially incised, and secured to an orogastric tube. By traction, the distal esophageal mucosa was inverted 10 cm proximally, then returned to the gastric lumen. In group A (n = 4), the mucosa (5 cm) was resected and the remnant was allowed to retract. In group B (n = 4), the mucosa was simply sutured back into its native position. In group C (n = 2), the mucosa (5 cm) was resected and the proximal segment was advanced and sutured to the gastric mucosa. At 6 weeks, or sooner if stricture developed, the animals were killed. Stricture formation was determined by ex vivo barium esophagram and gross assessment. The extent of fibrosis and epithelial healing were established histologically. RESULTS Group A (mucosa resected) developed weight loss and anorexia within 4 weeks. Pathology revealed dense fibrotic stricture without reepithelialization. Group B (mucosa elevated/replaced) gained weight after the operation. Histology demonstrated mucosal healing without significant stricture or fibrosis. Group C (mucosa resected/advanced) also thrived postoperatively. Histology confirmed mucosal healing without evidence of retraction or dense stricture. CONCLUSIONS Exposure of submucosal tissues causes esophageal stricture. Mucosal coverage minimizes submucosal fibrosis after injury. Mucosal resection and advancement allows healing without stricture and may have therapeutic potential for patients with Barrett's esophagus.

Abstract
BACKGROUND Laparoscopic fundoplication has become the standard for operative treatment of gastroesophageal reflux disease (GERD). METHODS We reviewed our experience with 1,000 consecutive patients receiving laparoscopic fundoplication for GERD (n = 882) or paraesophageal hernia (n = 118) between October 1991 and July 1999. Patients with achalasia and failed fundoplication were excluded from analysis. All the patients were evaluated preoperatively by upper endoscopy, esophageal manometry, and barium swallow. After 1994, 24-h pH monitoring was performed selectively in patients with extraesophageal symptoms and/or those without erosive esophagitis. There were 490 men 510 women in this review. Their mean age was 49 years. Procedures performed were 360 degrees floppy fundoplication (n = 879), 360 degrees fundoplication without fundus mobilization (Rossetti) (n = 22), 270 degrees posterior fundoplication (n = 96), and anterior fundoplication (n = 2). Esophageal lengthening procedure (Collis gastroplasty) was performed in combination with fundoplication in 15 patients. In seven patients the treatment was converted to open fundoplication. OUTCOMES The average length of hospitalization was 2.2 days, and 136 patients stayed longer than 2 days. Major complications occurred in 21 patients: esophageal perforation (n= 10), acute paraesophageal herniation (n = 4), splenic bleeding (n = 2), cardiac arrest (n = 1), pneumonia (n = 3), and testicular abscess (n = 1). Additional operations were required to manage the complications in 14 patients (70%): Four of these procedures were performed emergently, and 10 patients underwent reoperation between 6 h and 10 days. There were three deaths, all of which involved elderly patients with paraesophageal hernia. There were 35 late failures requiring reoperation for recurrence of GERD or development of new symptoms: The treatment of 32 patients was revised laparoscopically, and 4 patients required laparotomy. Beyond 1 year (median follow-up period, 27 months), 94% of the reviewed patients were satisfied with their surgical outcome.

Abstract
BACKGROUND A totally transoral outpatient procedure for the treatment of GERD would be appealing. METHODS A multicenter trial was initiated that included 64 patients with GERD treated with an endoscopic suturing device. Inclusion criteria were 3 or more heartburn episodes per week while not taking medication, dependency on antisecretory medicine, and documented acid reflux by pH monitoring. Exclusion criteria were dysphagia, grade 3 or 4 esophagitis, obesity, and hiatus hernia greater than 2 cm in length. Patients underwent manometry, endoscopy, 24-hour pH monitoring, and symptom severity scoring before and after the procedure. Patients were randomized to a linear or circumferential plication configuration. Adverse procedural events were recorded. RESULTS Mean 6-month symptom score changes demonstrated procedural efficacy. Heartburn severity and frequency as well as regurgitation all improved (p > 0.0001 for each). Twenty-four-hour pH monitoring showed improvement in number of episodes below pH of 4 at 3 and 6 months (p < 0.0007 and 0.0002) and percentage of total time the pH was less than 4 at 6 months (p < 0.011). Plication configuration did not affect symptoms or pH monitoring results. One patient had a self-contained suture perforation that was successfully treated with antibiotics. CONCLUSION Endoscopic gastroplasty is safe. It is associated with reduced symptoms and medication use at 6 month follow-up in patients with uncomplicated GERD.

Abstract
BACKGROUND Fundoplication hastens gastric emptying in pediatric patients with gastroesophageal reflux disease (GERD). However, among adult GERD patients with impaired gastric emptying, the degree of improvement offered by fundoplication and the value of pyloroplasty are less well defined. Therefore, we compared outcomes in GERD patients with delayed gastric emptying after fundoplication alone or fundoplication with pyloroplasty. METHODS Of 616 consecutive GERD patients who submitted to primary fundoplication (601 laparoscopic) between October 1991 and October 1997, 82 underwent preoperative solid-phase nuclear gastric emptying analysis. Of these, 25 had delayed gastric emptying (half-time >100 min). Of 12 patients with emptying half-times between 100 and 150 min, one underwent pyloroplasty at the time of Nissen fundoplication. Of 13 patients with emptying half-times >150 min, 11 had pyloroplasty at the time of Nissen fundoplication. Patients were asked to use a 0 ("none") to 4 ("incapacitating") scale to describe the severity of their symptoms of heartburn, regurgitation, dysphagia, bloating and diarrhea preoperatively and at 6 weeks and 1 year postoperatively. Eight patients consented to a postoperative analysis of gastric emptying. RESULTS One year after fundoplication, patients with delayed gastric emptying and controls reported a similar improvement in heartburn, regurgitation, and dysphagia, with no increase in undesirable side effects such as bloating and diarrhea. Among the patients with delayed gastric emptying who consented to undergo a repeat gastric emptying study after their operation, fundoplication alone provided a 38% improvement (p < 0.05) in gastric emptying, whereas fundoplication with pyloroplasty resulted in a 70% improvement in gastric emptying (p < 0.05). CONCLUSION Fundoplication improves gastric emptying. The addition of pyloroplasty results in even greater improvement and may have particular value for patients with severe gastric hypomotility.

Abstract
BACKGROUND Laparoscopic cancer surgery is limited by concerns about port-site metastasis. No study has definitively addressed the behavior and growth of tumor cells after the use of specific laparoscopic gases. METHODS In athymic rats, 10,000 colon cancer cells were injected intraperitoneally. The rats received either no pneumoperitoneum (pneumo) or pneumo (8 mmHg, 10 min) with carbon dioxide (CO(2)), nitrous oxide (N(2)O), or air. Two full-thickness incisions were made and closed in the upper abdomen of each animal. After 4 weeks, implants were identified grossly at necropsy, and invasiveness was scored according to penetration through the layers of the abdominal wall. RESULTS Rats receiving pneumo had more frequent implants (p < 0.01) with deeper penetration (p < 0.001) than rats not receiving pneumo. Implants were more common after air pneumo than after CO(2) (p < 0.05) or N(2)O (p = 0.07) pneumo, and were less penetrating after CO(2) pneumo than after air (p < 0.001) or N(2)O (p < 0.05) pneumo. CONCLUSIONS Carbon dioxide gas may limit the viability and invasiveness of free intraperitoneal tumor cells, as compared with air or N(2)O.

Abstract
BACKGROUND Outcomes assessment is being used increasingly to shape practice patterns in all areas of medicine. Although outcomes assessment is not a new concept, the widespread application of outcomes measurement for modifying practice is novel. Instead of focusing on results of interventions in highly controlled environments, outcomes studies usually report results as they occur in uncontrolled, real-world environments. Recently, the Society of American Gastrointestinal Endoscopic Surgeons (SAGES) has initiated a society-wide initiative to monitor outcomes in patients undergoing various laparoscopic operations. METHODS Pertinent literature is reviewed as it relates to outcomes assessment. The historical background underpinning the modern interest in outcomes is outlined. Definitions of terms useful for understanding outcomes research are given. The impact of outcomes assessment on minimally invasive surgery, both positive and negative, are examined. The SAGES outcome initiative is introduced. CONCLUSIONS Although outcomes studies usually do not provide information on the causes of observations made, they have gained in popularity because they provide information about patient perceptions of disease, disability, and treatment. Minimally invasive surgical procedures often are reported in terms of outcomes assessment because a controlled clinical trial was rendered impossible by early and widespread application of laparoscopic surgery. The SAGES outcomes initiative will provide the necessary tools for the participation of surgeons in the process of practice profiling.

Abstract
The uncut Roux limb operation is designed to have the benefits of a Roux limb but still have electrical continuity from proximal to distal bowel, thus eliminating the risk of Roux stasis syndrome. The main complication has been recanalization of the uncut staple line leading to bile reflux. This study aims to employ a new technique, which will not allow recanalization of an uncut staple line but will not interfere with normal bowel myoelectric activity. Fourteen mongrel dogs, 25 to 35 kg, underwent a midline laparotomy under general anesthesia. An uncut staple line was placed 25 cm from the ligament of Treitz. In seven animals an uncut staple line alone was placed, and in the other seven animals the bowel was stapled between a sandwich of Teflon reinforcing strips such that the staples were held on both sides of the bowel by the Teflon. A jejunojejunostomy was placed 6 cm proximal to the staple line. Insulated bipolar electrical leads were placed around the staple line. After the electrical leads were monitored 2 days to 3 months postoperatively for bowel myoelectric activity, The animals were killed and the operative sites inspected. No animal suffered morbidity or mortality from the procedure. All seven unreinforced staple lines recanalized and all seven reinforced staple lines remained competent. The duodenal pacemaker potentials were transmitted through the staple line in five animals (3 controls and 2 with Teflon reinforcement) with in 1 week postoperatively. The uncut staple line does not reliably transmit the duodenal pacemaker potentials. The staple line does not recanalize when it is reinforced with a permanent material, increasing the utility of the "uncut" Roux limb operation.

Abstract
Toupet (270 degrees) fundoplication is commonly recommended for patients with gastroesophageal reflux (GER) and esophageal dysmotility. However, Toupet fundoplication may be less effective at protecting against reflux than Nissen (360 degrees) fundoplication. We therefore compared the effectiveness and durability of both types of fundoplication as a function of preoperative esophageal motility. From January 1992 through January 1998, 669 patients with GER underwent laparoscopic fundoplication (78 Toupet, 591 Nissen). Patients scored heartburn, regurgitation, and dysphagia preoperatively, and at 6 weeks and 1 year postoperatively, using a 0 ("none") to 3 ("severe") scale. We compared symptom scores (Wilcoxon rank sum test) and redo fundoplication rates (Fisher exact test) in Toupet and Nissen patients. We also performed subgroup analyses on 81 patients with impaired esophageal motility (mean peristaltic amplitude, <30 mm Hg or peristalsis <70% of wet swallows) and 588 patients with normal esophageal motility. Toupet and Nissen patients reported similar preoperative heartburn, regurgitation, and dysphagia. At 6 weeks after operation, heartburn and regurgitation were similarly improved in both groups, but dysphagia was more prevalent among Nissen patients. After 1 year, heartburn and regurgitation were re-emerging in Toupet patients, and dysphagia was again similar between groups. Patients with impaired motility who have Nissen fundoplication are no more likely to suffer persistent dysphagia than their counterparts who have Toupet fundoplication. In addition, patients with normal motility are more likely to develop symptom recurrence after Toupet fundoplication than Nissen fundoplication, with no distinction in dysphagia rates. We conclude that since Toupet patients suffer more heartburn recurrence than Nissen patients, with similar dysphagia, selective use of Toupet fundoplication requires further study.

Abstract
Endogastric surgery is a branch of minimally invasive surgery that combines flexible endoscopy and laparoscopy. By placing trocars directly into the stomach, quite a number of procedures may be performed. Leiomyomas and other benign gastric tumors are readily removed, and in Asia early gastric cancers are removed with these techniques. Large pancreatic pseudocysts abutting the posterior wall of the stomach may be drained through the stomach using an endogastric approach. Lastly, intragastric bleeding in areas not reachable with a conventional endoscope may be approached with an endogastric approach. Although the indications for these procedures are-in general-rare, they are not difficult to perform, and outcomes have been superb.

Abstract
Solid-phase gastric emptying is linear. Therefore, the authors calculated gastric-emptying half-time, the time for half of the ingested solids or liquids to leave the stomach, with the conventional multiple-point method and the proposed two-point method (at 0 and 120 minutes) in retrospective and prospective studies of 50 patients each. The results showed excellent correlation. Results with the two-point method were comparable to those with the multiple-point method, and the two-point method substantially reduced technologist and camera times.

Abstract
OBJECTIVE To determine rates and mechanisms of failure in 857 consecutive patients undergoing laparoscopic fundoplication for gastroesophageal reflux disease or paraesophageal hernia (1991-1998), and compare this population with 100 consecutive patients undergoing fundoplication revision (laparoscopic and open) at the authors' institution during the same period. SUMMARY BACKGROUND DATA Gastroesophageal fundoplication performed through a laparotomy or thoracotomy has a failure rate of 9% to 30% and requires revision in most of the patients who have recurrent or new foregut symptoms. The frequency and patterns of failure of laparoscopic fundoplication have not been well studied. METHODS All patients undergoing fundoplication revision were included in this study. Symptom severity was scored before and after surgery by patients on a 4-point scale. Evaluation of patients included esophagogastroscopy, barium swallow, esophageal motility, 24-hour ambulatory pH, and gastric emptying studies. Statistical analysis was performed with multiple chi-square analyses, Fisher exact test, and analysis of variance. RESULTS Laparoscopic fundoplication was performed in 758 patients for gastroesophageal reflux disease and in 99 for paraesophageal hernia. Median follow-up was 2.5 years. Thirty-one patients (3.5%) have undergone revision for fundoplication failure. The mechanism of failure was transdiaphragmatic herniation of the fundoplication in 26 patients (84%). In 40 patients referred from other institutions, after laparoscopic fundoplication, only 10 (25%) had transdiaphragmatic migration (p < 0.01); a slipped or misplaced fundoplication occurred in 13 patients (32%), and a twisted fundoplication in 12 patients (30%). The failure mechanisms of open fundoplication (29 patients) followed patterns previously described. Fundoplication revision procedures were initiated laparoscopically in 65 patients, with six conversions (8%). The morbidity rate was 4% in laparoscopic procedures and 9% in open ones. There was one death, from aspiration and adult respiratory distress syndrome after open fundoplication. A year or more after revision operation, heartburn, chest pain, and dysphagia were rare or absent in 88%, 78%, and 91%, respectively, after laparoscopic revision, and were rare or absent in 91%, 83%, and 70%, respectively, after open revision, but 11 patients ultimately required additional operations for continued or recurrent symptoms, 3 after open revision (17%), and 8 after laparoscopic fundoplication (11%). CONCLUSIONS Laparoscopic fundoplication failure is infrequent in experienced hands; the rate may be further reduced by extensive esophageal mobilization, secure diaphragmatic closure, esophageal lengthening (applied selectively), and avoidance of events leading to increased intraabdominal pressure. When revision is required, laparoscopic access may be used successfully by the laparoscopically experienced esophageal surgeon.

Abstract
An association between gastroesophageal reflux (GER) and asthma has been suggested for many decades. Although antireflux therapy (medical and surgical) has been shown to be beneficial in patients with asthma, response to therapy has not been well quantified. The aim of this study was to evaluate long-term outcome in patients with asthma and associated GER undergoing fundoplication. From a database of more than 600 patients with GER treated surgically between 1991 and 1996, 39 patients with asthma as their primary indication for surgery were identified. Asthma symptom scores were determined using the National Asthma Education Program classification, and medication frequency scores were determined preoperatively and at latest follow-up (median follow-up 2.7 years). Comparisons were made using the Wilcoxon rank-sum test. Asthma symptom scores decreased significantly after antireflux surgery. More important, the medication scores for use of systemic corticosteroids decreased significantly postoperatively (2.2 preoperatively vs. 0.7 postoperatively; P = 0.0001). Of the nine patients who required daily oral corticosteroids, seven have discontinued treatment entirely (78%). In patients with asthma associated with GER, symptoms of asthma are improved following fundoplication. Especially important has been the ability to wean patients from systemic corticosteroids postoperatively. Fundoplication should be offered to those patients with GER-associated asthma, especially those who are steroid dependent.

Abstract
BACKGROUND Clinically relevant surgical outcomes are usually monitored by surgeons only for new and/or high-volume procedures. Prospective outcomes audit studies are rarely done on 100% of procedures performed by a single surgeon, a surgical practice, or an institution. Therefore, we set out to determine the resource utilization and accuracy of a well-validated system at its introduction into a North American university surgical practice. METHODS The Otago Surgical Audit, which has been validated in a wide spectrum of surgical practices in Australasia, was applied to a university practice in general and laparoscopic surgery. Data were recorded by the surgeon on the day of operation, at discharge, and during any subsequent readmission. Resource utilization was determined by timing the important steps in data acquisition and computer entry. Data accuracy was assessed by an independent chart review of 22% of all records. Case capture was audited by reviewing operating room case logs. RESULTS Over 1 year, from October 1, 1996 to September 30, 1997, 338 procedures were performed. Data recording and coding by the surgeon required 2 min per form, or a total of 676 min (11.3 h) annually. Data entry required 2.11 min per form, or a total of 713 min (11.9 h) for the year. Eight percent of cases were returned to the surgeon for additional information. In the medical record audit, no additional mortality or readmissions were discovered, and one minor complication was recorded in the hospital record but not the outcomes audit. One complication and three operations recorded in the audit database were omitted from operating room records. Two minor procedures on the operating room log were omitted from the audit database. Operating time reported by the surgeon averaged 19 min less than recorded in the operative log. Data accuracy and coding accuracy improved significantly between the 1st month (month 4) and the 2nd month audited (month 12), (p <.01). CONCLUSIONS It is possible to perform a 100% clinical outcome audit with the use of minimal resources. When the surgeon is involved with data acquisition and coding, the accuracy and completeness of the log may outstrip the medical record, but a learning curve of 4-6 months may be required to achieve this goal.

Abstract
There are several studies that suggest that aspirin (acetylsalicylic acid [ASA]) and nonsteroidal anti-inflammatory drugs (NSAIDs) are associated with esophagitis or esophageal stricture formation. There are limited data on the potential of low-dose ASA and over-the-counter (OTC) NSAIDs to cause esophageal injury. The goal of this study was to determine whether there is an association between esophageal strictures and ASA/NSAID use, including low-dose ASA and OTC NSAIDs. A total of 79 consecutive patients (mean age, 52.8 years; 38 men, 41 women) referred for endoscopy from 4/1/96 to 11/15/96 for chronic gastroesophageal reflux disease symptoms were evaluated. Data collected include gender, race, and age, NSAID or ASA use, as well as an assessment of dysphagia, heartburn duration, and heartburn frequency. Patients taking NSAIDs or ASA at least twice a week were considered ASA/NSAID users. There were 46 patients without strictures and 33 patients with peptic strictures. Patients with strictures were older than patients without strictures (mean age, 58.7 versus 48.6 years; p < 0.01), had longer duration of heartburn symptoms (8.6 versus 6.4 years, p < 0.05), and were more likely to have mucosal injury (50% versus 26.1%). Stricture patients were more likely to use ASA/NSAIDs (63.6% versus 26.1%; p < 0.01). In particular, stricture patients were more likely to use low-dose ASA than patients without strictures (30.3% versus 2.2%; p < 0.01). Otherwise, there were no significant differences with regard to gender, race, or heartburn duration or frequency. Linear regression analysis showed that ASA/NSAID use had a greater influence on the incidence of peptic strictures than age. There is an association between esophageal stricture and ASA/NSAID use, which includes OTC NSAIDs and low-dose ASA.

Abstract
BACKGROUND Columnar-lined esophagus with intestinal metaplasia (IM), also called Barrett's esophagus, is a manifestation of severe gastroesophageal reflux (GER) and may predict poor symptom relief and high failure rate after fundoplication. We compared symptom scores and reoperation rates in GER patients with and without Barrett's esophagus. METHODS Between July 1992 and July 1997, 646 patients underwent fundoplication (626 laparoscopic). Of 150 endoscopic biopsies of suspected columnar-lined esophagus, 80 confirmed IM, 50 identified cardiac or fundic epithelium, and 20 revealed only esophagitis. Typical GER symptoms were scored by patients preoperatively and postoperatively (0 to 4 scale). We compared symptom response (Wilcoxon rank sum test) and failure rates (t test) in patients with IM and GER controls without IM. Preoperative data were available for 74 IM patients and 496 controls. One-year follow-up was available in 45 IM patients and 301 controls. Intermediate follow-up (2 to 5 years) was available in 20 IM patients and 99 controls. RESULTS Preoperatively and postoperatively, patients with IM reported heartburn, regurgitation, and dysphagia scores similar to controls. Procedure failure, requiring redo fundoplication, appeared more likely in IM patients than controls (6.3% versus 2.5%), but this difference did not reach statistical significance (P = 0.061). CONCLUSION Fundoplication provides equivalent symptom relief for patients with and without IM.

Abstract
Incompetence of the lower esophageal sphincter mechanism leads to gastroesophageal reflux (GER), which is the most common indication for surgery of the gastroesophageal junction. Evaluation, diagnosis, and the modern surgical treatment of GER are discussed. Evaluation of patients with severe heartburn include upper endoscopy to evaluate the general condition of the esophagus, stomach, and duodenum; an upper gastrointestinal contrast study for a complete anatomic view of the esophagus and stomach; esophageal manometry to evaluate the function of the esophagus; 24-hour pH monitoring to determine esophageal acid exposure; and a gastric emptying study selectively to determine the presence of a motility disorder. These studies most often prove the diagnosis of gastroesophageal reflux, hiatal hernia, Barrett's esophagus, peptic esophageal stricture, paraesophageal hernia, or achalasia. The laparoscopic approach to treatments for these include Nissen fundoplication, Toupet fundoplication, Collis gastroplasty with fundoplication, modified Heller myotomy, esophageal diverticulectomy, and revisional operations. These procedures are described in detail. The results of these operations indicate that they are safe and effective and should be considered the new gold standard for correction of gastroesophageal pathology. Laparoscopic surgery has revolutionized many procedures traditionally performed through a laparotomy. Although they are technically more difficult and require a significant amount of time and practice for the surgeon to become proficient, it is becoming apparent that for functional surgery of the gastroesophageal junction laparoscopy is the access of choice.
