Abstract
Abstract
Objective
Elderly patients undergo bariatric surgery less frequently than younger patients. Short- and medium-term outcomes after bariatric surgery in the elderly population remain largely unknown. The objective of the present retrospective, registry-based cohort study was to compare short- and medium-term outcomes between patients <65 and ≥65 years undergoing bariatric surgery, hypothesizing similar outcomes between groups.
Methods
In this retrospective, registry-based cohort study, the Ontario Bariatric Registry was used to compare data of patients <65 and ≥65 years who underwent Roux-en-Y gastric bypass and sleeve gastrectomy between January 2010 and August 2019 in all accredited bariatric centers of excellence in Ontario, Canada. Primary outcomes were overall postoperative complications. Secondary outcomes included early (<30 days) complications, readmissions, reoperations, mortality, weight loss and comorbidities improvement at 1 and 3 year after surgery.
Results
Data of 22,981 patients <65 and 532 patients ≥65 years were analyzed. Overall postoperative complications were similar between patients <65 and ≥65 years (3388/22,981 [14.7%] vs. 73/532 [13.7%], p = 0.537). Early (<30 days) postoperative complications, readmissions, reoperations, and mortality rates were also similar between groups. Both groups had significant weight loss and comorbidities improvement at 1- and 3-year follow-up. Patients <65 years had superior weight loss (+3.5%, 95% CI: 1.6–5.4, p < 0.001) and higher rates of remission for diabetes mellitus (63.8% vs. 39.3%, p < 0.001), hypertension (37.9% vs. 14.5%, p < 0.001), dyslipidemia (28.2% vs. 9.5%, p < 0.001) and gastroesophageal reflux (65.1% vs. 24.0%, p < 0.001) compared to patients ≥65 years at 3 year.
Conclusion
Patients <65 and ≥65 years had similar perioperative morbidity and mortality after bariatric surgery. Even though patients <65 years had overall better medium-term outcomes, bariatric surgery is safe and yields significant weight loss and comorbidities improvement in patients ≥65 years.

Abstract
Abstract
Objective
Single-anastomosis duodenal switch (SADS) has emerged in recent years as an alternative to the standard double-anastomosis duodenal switch (DADS). The objective of this study was to compare short- and medium-term outcomes between SADS and DADS.
Methods
Data collected in the Ontario Bariatric Registry between 2010 and 2019 were used for this retrospective study to determine outcomes of patients undergoing primary laparoscopic SADS versus DADS at a Canadian tertiary hospital and bariatric center of excellence. The primary outcome was weight loss at 1 and 2 years after surgery. Short-term secondary outcomes included operative times, intra- and early postoperative complications, hospital length of stay (LOS), and 30-day readmissions. Medium-term secondary outcomes included late postoperative complications as well as nutritional deficiencies and persistent diarrhea at 1 and 2 years after surgery. Subgroup analyses were performed to compare patients undergoing one- and two-stage procedures.
Results
Data of 107 patients who underwent SADS (n = 25) or DADS (n = 82) were included in the study. Follow-up data were available for 59/107 (55.1%) patients at 1 year and 47/107 (43.9%) at 2 years after surgery. Patients in the SADS and DADS groups had similar %TBWL at 1 year (23.6 versus 26.2, P = 0.617) and 2 years (24.8 versus 30.2, P = 0.116) after surgery. Short- and medium-term outcomes were similar between groups. There was no difference between patients undergoing one- versus two-stage procedures.
Conclusion
This study showed that patients undergoing SADS and DADS had similar weight loss at 1 and 2 years. Early and late postoperative morbidity, operative times, early readmissions, and LOS were also similar between groups. Further studies with longer follow-up are required to confirm these results.

Abstract
BACKGROUND Comparative international practice of patients undergoing bariatric-metabolic surgery for type 2 diabetes mellitus (T2DM) is unknown. We aimed to ascertain baseline age, sex, body mass index (BMI) and types of operations performed for patients with T2DM submitted to the IFSO Global Registry. MATERIALS AND METHODS Cross-sectional analysis of patients having primary surgery in 2015-2018 for countries with ≥90% T2DM data completion and ≥ 1000 submitted records. RESULTS Fifteen countries including 11 national registries met the inclusion criteria. The rate of T2DM was 24.2% (99,537 of 411,581 patients, country range 12.0-55.1%) and 77.1% of all patients were women. In every country, patients with T2DM were older than those without T2DM (overall mean age 49.2 [SD 11.4] years vs 41.8 [11.9] years, all p < 0.001). Men were more likely to have T2DM than women, odds ratio (OR) 1.68 (95% CI 1.65-1.71), p < 0.001. Men showed higher rates of T2DM for BMI <35 kg/m2 compared to BMI ≥35.0 kg/m2, OR 2.76 (2.52-3.03), p < 0.001. This was not seen in women, OR 0.78 (0.73-0.83), p < 0.001. Sleeve gastrectomy was the commonest operation overall, but less frequent for patients with T2DM, patients with T2DM 54.9% vs without T2DM 65.8%, OR 0.63 (0.63-0.64), p < 0.001. Twelve out of 15 countries had higher proportions of gastric bypass compared to non-bypass operations for T2DM, OR 1.70 (1.67-1.72), p < 0.001. CONCLUSION Patients with T2DM had different characteristics to those without T2DM. Older men were more likely to have T2DM, with higher rates of BMI <35 kg/m2 and increased likelihood of food rerouting operations.

Abstract
INTRODUCTION Bariatric surgery patients experience an increased risk of venous thromboembolism (VTE), however, the optimal dose of low-molecular-weight heparin for VTE prophylaxis remains uncertain. Currently, St. Joseph's Healthcare Hamilton utilizes a weight-adjusted tinzaparin dosage (50 to 75 units/kg rounded to nearest pre-filled syringe) for postoperative VTE prophylaxis. OBJECTIVES This study analyzed the safety of weight-adjusted tinzaparin for VTE prophylaxis in bariatric surgery patients weighing ≥160 kg. METHODS This was a retrospective study involving patients weighing ≥160 kg that underwent bariatric surgery from September 2015 to September 2019. Patients received a single dose of weight-adjusted subcutaneous unfractionated heparin (UFH) [5000 or 7500 IU] immediately prior to surgery, subcutaneous UFH [5000 IU, 7500 IU, or unspecified] immediately postoperatively, and either 10,000 or 14,000 IU of tinzaparin, beginning on the day after surgery, for 10 days. Intra-operative sequential compression devices could be used at the attending surgeon's discretion. Occurrence of VTE and major bleeding within 30 days of surgery were assessed. RESULTS A total of 389 patients were included for analysis, all patients received in-hospital follow-up while 349 patients had also 30-day follow-up. For the primary safety and efficacy analysis of in-hospital events, VTE and major bleeding rates were 0.26% [95% CI 0.01%-1.44%] (1/389) and 0.77% [95% CI 0.21%-2.24%] (3/389) respectively. For patients with 30-day follow-up VTE and major bleeding rates were 0.57% [95% CI 0.1%-2.07%] (2/349) and 1.43% [95% CI 0.61%-3.3%] (5/349) respectively. CONCLUSIONS Weight-adjusted tinzaparin was associated with a low risk of bleeding and VTE events, supporting its use for VTE prophylaxis for patients weighing ≥160 kg.

Abstract
Essentials The optimal dose and duration of thromboprophylaxis after bariatric surgery are unclear. We evaluated the safety of weight-adjusted tinzaparin prophylaxis in 1212 patients. In-hospital rates of venous thromboembolism and major bleeding were 0.2% and 1.8% respectively. In a sub-set of patients, trough anti-Xa levels did not show excessive anticoagulant activity. SUMMARY Background Patients undergoing bariatric surgery are at moderate to high risk of venous thromboembolism (VTE). The optimal dose and duration of anticoagulant prophylaxis is uncertain. Objective To evaluate the safety of extended-duration weight-adjusted tinzaparin after bariatric surgery. Patients/methods We conducted a single-center retrospective cohort study of consecutive patients undergoing bariatric surgery who received weight-adjusted tinzaparin 4500-14 000 IU daily (75 IU kg-1 rounded to the nearest prefilled syringe) for 10 days after surgery (7-9 days post-hospital discharge). Primary safety outcomes were the frequency of VTE and major bleeding within 30 days of surgery in patients receiving at least one dose of tinzaparin. Results A total of 1279 patients undergoing bariatric surgery between July 2009 and December 2012 were reviewed, of whom 1212 received weight-adjusted tinzaparin. Safety outcomes were collected for 819 patients at 30 days, and for 1212 patients in-hospital only. The median age was 45.0 years, median weight was 130.0 kg and 98.8% of patients underwent gastric bypass or sleeve gastrectomy. In patients completing 30 days of follow-up, VTE occurred in 4/819 (0.5%) and major bleeding occurred in 13/819 patients (1.6%). In-hospital rates of VTE and major bleeding during surgical admission were 3/1212 (0.2%) and 22/1212 (1.8%), respectively. Conclusions Extended thromboprophylaxis with weight-adjusted tinzaparin appears to be a safe strategy after bariatric surgery, with low rates of postoperative VTE and major bleeding.

Abstract
Roux-en-Y gastric bypass (RYGB) is associated with the remission of type 2 diabetes mellitus (DM). There are a number of scoring systems available that help predict type 2 diabetes remission rates after bariatric surgery; however, relatively few have been validated externally. The DiaRem score, comprised of four preoperative variables (age, haemoglobin A1c [HbA1c], sulfonylurea and insulin-sensitizing agent use and insulin use), allows for the identification of patients who are most likely to have DM remission following RYGB. Our primary objective was to determine the variables predictive of DM remission 1 year post-RYGB, determine how well the DiaRem score predicts DM remission 1 year post-RYGB and identify the optimal cut-off DiaRem score. The study is based on results of RYGB performed across multiple centres in Ontario, Canada, overseen by the Centre for Surgical Invention and Innovation in Hamilton, with direction from the Ontario Bariatric Network. Regression analysis was used to determine the predictive value of demographic and clinical variables and that of the DiaRem score. The optimal DiaRem cut-off score was determined using sensitivity and specificity analysis. Of 3874 patients in the Ontario Bariatric Registry between January 2010 and February 2015, 915 had complete 1-year follow-up data. Among these, 15 were not classified as having DM at baseline and were excluded. Of the remaining 900 patients with type 2 diabetes and who underwent RYGB surgery, 333 (37.0%) had DM remission at 1-year follow-up. Three of four DiaRem variables (age, HbA1c, insulin use), in addition to use of any hypoglycaemic agent, were associated with DM remission. DiaRem score had moderate predictive value. A DiaRem score cut-off of <5 had a sensitivity of 71.8% and specificity of 71.3%. This study provides guidance to clinicians in using the DiaRem score to inform the selection and prioritization of patients to ensure timely access to bariatric surgery for those who are likely to benefit the most.

Abstract
Abstract
Background
In countries with universal health coverage, the delivery of care should be driven by need. However, other factors, such as proximity to local facilities or neighbourhood socioeconomic status, may be more important. The objective of this study was to evaluate which geographic and socioeconomic factors affect the delivery of bariatric care in Canada.
Methods
This was a national retrospective cohort study of all adult patients undergoing bariatric surgery between April 2008 and March 2015 in Canada (excluding Quebec). The main outcome was neighbourhood rate of bariatric surgery per 1000 obese individuals (BMI over 30 kg/m2). Geographic cluster analysis and multilevel ordinal logistic regression were used to identify high-use clusters, and to evaluate the effect of geographic and socioeconomic factors on care delivery.
Results
Having a bariatric facility within the same public health unit as the neighbourhood was associated with a 6·6 times higher odds of being in a bariatric high-use cluster (odds ratio (OR) 6·60, 95 per cent c.i. 1·90 to 22·88; P = 0·003). This finding was consistent across provinces after adjusting for utilization rates. Neighbourhoods with higher obesity rates were also more likely to be within high-use clusters (OR per 5 per cent increase: 2·95, 1·54 to 5·66; P = 0·001), whereas neighbourhoods closer to bariatric centres were less likely to be (OR per 50 km: 0·91, 0·82 to 1·00; P = 0·048).
Conclusion
In this study, across provincial healthcare systems with high and low utilization, the delivery of care was driven by the presence of local facilities and neighbourhood obesity rates. Increasing distance to bariatric centres substantially influenced care delivery.

Abstract
The aim of this study was to survey the impact of alcohol consumption on sperm parameters and DNA integrity in experimentally induced diabetic mice. A total of 32 adult male mice were divided into four groups: mice of group 1 served as control fed on basal diet, group 2 received streptozotocin (STZ) (200 mg kg(-1) , single dose, intraperitoneal) and basal diet, group 3 received alcohol (10 mg kg(-1) , water soluble) and basal diet, and group 4 received STZ and alcohol for 35 days. The cauda epididymidis of each mouse was dissected and placed in 1 ml of pre-warm Ham's F10 culture medium for 30 min. The swim-out spermatozoa were analysed for count, motility, morphology and viability. Sperm chromatin quality was evaluated with aniline blue, toluidine blue, acridine orange and chromomycin A3 staining. The results showed that all sperm parameters had significant differences (P < 0.05), also when sperm chromatin was assessed with cytochemical tests. There were significant differences (P < 0.001) between the groups. According to our results, alcohol and diabetes can cause abnormalities in sperm parameters and chromatin quality. In addition, alcohol consumption in diabetic mice can intensify sperm chromatin/DNA damage.

Abstract
Genetic factors, including cytokine gene polymorphisms, are potential contributors to the pathogenesis of the Graves' disease (GD). We attempted in this study to determine the association between GD and the following polymorphisms in the interleukin-1 (IL-1) family genes: IL-1alpha (-889C/T), IL-1ss (-511C/T), IL-1ss (+3962C/T), IL-1R (Pst-1 1970C/T) and IL-1RA (Mspa-I 11100C/T). We studied 107 patients with an established diagnosis of GD and 140 healthy controls. Cytokine typing was performed by the polymerase chain reaction with sequence-specific primers assay. Genotype distributions among patients were in Hardy-Weinberg equilibrium for all polymorphisms. The frequency of the IL-1alpha -889T allele was significantly higher in patients than in controls (51.9% vs. 31.6%, OR=2.33, 95% CI=1.61-3.38; p<0.0001). The IL-1RA Msp-I 11100C allele was significantly more frequent in patients than in controls (50.0% vs. 22.9%, OR=3.38, 95% CI=2.29-4.97, p<0.0001). No significant associations were found for other polymorphisms. Although the IL-1 family has well-known roles in GD pathogenesis, the contributions of their genetic variations to the disease are unclear. In this study, we documented a highly significant association between GD and polymorphism in IL-1alpha and IL-1RA genes. Further studies in other populations are necessary to confirm our results.

Abstract
AIM/HYPOTHESIS The aim of the study was to determine the annual healthcare expenditures of an individual with diabetes in Tehran, between March 2004 and March 2005. METHODS This prevalence-based 'cost-of-illness' study was conducted in two phases. In the first phase, 23,707 randomly selected individuals were interviewed to gather a cohort of participants with diabetes. In the second phase, 710 diabetic patients and 904 age- and sex-matched controls were followed up for 1 year at intervals of 3 months and the direct (physician services, medications and devices, hospitalisation, laboratory, paraclinical and transport) and indirect (loss of productivity) expenditures were recorded. The excess costs of a person with diabetes were estimated through comparison with matched controls. The estimates were also extrapolated to the total population of Tehran and Iran. The costs were converted from the Iranian rial to the US dollar (exchange rate September 2004). RESULTS Total annual direct costs of diabetic and control participants were $152.3 +/- 14.5 and $52.0 +/- 5.8, respectively, which is indicative of 2.92 times higher costs in diabetic patients. The most expensive components of direct costs were medications and devices, and hospitalisation in diabetic patients (28.7% and 28.6%, respectively). Total indirect costs were $39.6 +/- 2.4 and $16.7 +/- 1.1 in diabetic and non-diabetic individuals. The aggregate annual direct costs of diabetes were estimated to be $112.424 +/- 10.732 million and $590.676 +/- 65.985 million in Tehran and Iran, respectively. Diabetes complications contributed 53% of the aggregate excess direct costs of diabetes. CONCLUSIONS/INTERPRETATION Diabetes is an expensive medical problem in Iran and planning of national programmes for its control and prevention is necessary.

Abstract
BACKGROUND A new medical device uses high-frequency electrical algorithms to create intermittent vagal blocking (VBLOC therapy). The aim is to assess the effects of vagal blocking on excess weight loss (EWL), safety, dietary intake, and vagal function. METHODS An open-label, 3-center study was conducted in obese subjects (body mass index [BMI] 35-50 kg/m(2)). Electrodes were implanted laparoscopically on both vagi near the esophagogastric junction to provide electrical block. Patients were followed for 6 months for body weight, safety, electrocardiogram, dietary intake, satiation, satiety, and plasma pancreatic polypeptide (PP) response to sham feeding. To specifically assess device effects alone, no diet or exercise programs were instituted. RESULTS Thirty-one patients (mean BMI, 41.2 +/- 1.4 kg/m(2)) received the device. Mean EWL at 4 and 12 weeks and 6 months after implant was 7.5%, 11.6%, and 14.2%, respectively (all P < .001); 25% of patients lost >25% EWL at 6 months (maximum, 36.8%). There were no deaths or device-related serious adverse events (AEs). Calorie intake decreased by >30% at 4 and 12 weeks and 6 months (all P <or= .01), with earlier satiation (P < .001) and reduced hunger (P = .005). After 12 weeks, plasma PP responses were suppressed (20 +/- 7 vs 42 +/- 19 pg/mL). Average percent EWL in patients with PP response <25 pg/mL was double that with PP response >25 pg/mL (P = .02). Three patients had serious AEs that required brief hospitalization, 1 each for lower respiratory tract, subcutaneous implant site seroma, and Clostridium difficile diarrhea. CONCLUSIONS Intermittent, intra-abdominal vagal blocking is associated with significant EWL and a desirable safety profile.

Abstract
On 28 February 2003, the world's first telerobotic surgical service was established between St. Joseph's Healthcare Hamilton, a teaching hospital affiliated with McMaster University, and North Bay General Hospital, a community hospital 400 km away. The service was designed to provide telerobotic surgery and assistance by expert surgeons to local surgeons in North Bay, and to improve the range and quality of advanced laparoscopic surgeries offered locally. The two surgeons have collaboratively performed 22 remote telepresence surgeries including laparoscopic fundoplications, laparoscopic colon resections, and laparoscopic inguinal hernia repairs. This article describes the important lessons learned, including the telecommunication requirements, the impact from lack of haptic feedback, surgeons' adaptation to latency, and ethical and medicolegal issues. This is currently the largest clinical experience with assisted robotic telepresence surgery (ARTS) in the world, and the lessons learned will help guide the future design and development of telesurgical robotic platforms. It also will guide the establishment of telesurgical networks connecting various centers in the world, allowing for rapid and safe dissemination of new surgical techniques.

Abstract
OBJECTIVE We report on 3 patients who underwent laparoscopic antireflux procedures for persistent symptoms of GERD after biopolymer injection. METHODS Experienced laparoscopic surgeons completed all 3 procedures laparoscopically. In 2 patients, there was an extramural extravasation of the polymer outside and adherent to the esophageal wall. In these patients, a partial posterior fundoplication was used. The third patient, who had the polymer material deposits removed preoperatively by endoscopic mucosal resection, underwent a Nissen fundoplication. RESULTS Postoperative recovery was uneventful in all cases. At follow-up of 6 to 12 months, all patients were symptom free, off medical therapy, and experiencing no dysphagia. CONCLUSION Surgical therapy for patients after failed biopolymer injection is safe and effective. The choice of surgery may depend on whether the polymer mass can be removed preoperatively.

Abstract
PURPOSE The aim of this study was to assess whether telementoring and telerobotic assistance would improve the range and quality of laparoscopic colorectal surgery being performed by community surgeons. METHODS We present a series of 18 patients who underwent telementored or telerobotically assisted laparoscopic colorectal surgery in two community hospitals between December 2002 and December 2003. Four community surgeons with no formal advanced laparoscopic fellowship were remotely mentored and assisted by an expert surgeon from a tertiary care center. Telementoring was achieved with real-time two-way audio-video communications over bandwidths of 384 kbps-1.2 mbps and included one redo ileocolic resection, two right hemicolectomies, two sigmoid resections, three low anterior resections, one subtotal colectomy, one reversal of a Hartmann operation, and one abdominoperineal resection. A Zeus TS microjoint system (Computer Motion Inc, Santa Barbara CA) was used to provide telepresence for the telerobotically assisted laparoscopic procedures, which included three right hemicolectomies, three sigmoid resections, and one low anterior resection. RESULTS There were no major intraoperative complications. There were two minor intraoperative complications involving serosal tears of the colon from the robotic graspers. In the telementored cases, there were two postoperative complications requiring reoperation (intra-abdominal bleeding and small bowel obstruction). Two telementored procedures were converted because of the mentee's inability to find the appropriate planes of dissection. One telerobotically assisted procedure was completed laparoscopically by the local surgeon with aid of telementoring because of inadequate robotic arm position. The median length of hospital stay for this series was 4 days. The surgeons considered telementoring useful in all cases (median score 4 out of 5). The use of remote telerobotic assistance was also considered a significant enabling tool. CONCLUSIONS Telementoring and remote telerobotic assistance are excellent tools for supporting community surgeons and providing patients better access to advanced surgical care.

Abstract
BACKGROUND Laparoscopic Nissen fundoplication (LNF) efficiently controls the symptoms of gastroesophageal reflux disease (GERD); however, other nonspecific gastrointestinal (GI) symptoms have been reported following LNF. The aim of this study was to evaluate the long-term effects of LNF on nonspecific GI complaints. METHODS The basis for this study is the prospective follow-up of 515 patients (mean age 46 +/- 13 years) who underwent a LNF between 1992 and 1998. A questionnaire was designed to evaluate GERD symptoms (i.e., heartburn, epigastric pain, regurgitation, dysphagia, and fullness, score 0-60) and nonspecific GI symptoms (i.e., vomiting, diarrhea, constipation, and lack of appetite, score 0-48). Patients were assessed before surgery, at 6 months, 2 years, and 5 years after surgery. RESULTS Laparoscopic Nissen fundoplication was associated with a significant decrease in both GERD and nonspecific GI symptoms score at 6 months and up to 5 years, in the whole group (p < 0.001). 360 patients (69.7%) had preoperative nonspecific GI symptoms and experienced a significant reduction in these symptoms following the surgery and lasting up to 5 years. The other 155 patients (30.3%) had no preoperative GI symptoms (GI symptoms score of 0). In this group, there was a small but statistically significant increase in GI symptoms score (p < 0.001). It was, however, clinically significant (defined as a score >12) in only 9.9% of the patients. CONCLUSIONS Laparoscopic Nissen fundoplication provides an efficient treatment of GERD up to 5 years, and in a majority of patients, it is not associated with any significant increase in nonspecific GI complaints. New nonspecific bowel symptoms can develop after LNF in some patients but are unlikely to be clinically significant.

Abstract
Achalasia is dominated by injury to inhibitory nerves. As intramuscular interstitial cells of Cajal (ICC-IM) are proposed to form functional units with nitrergic nerves, their fate in achalasia may be critically important. We studied the relationship between loss of nitrergic nerves and injury to ICC-IM in patients with achalasia and determined associations between ICC-IM and mast cells (MC), using quantitative immunohistochemistry and electron microscopy. Loss of neuronal nitric oxide synthase (nNOS) immunoreactivity was completed within 3 years of acquiring achalasia. Thereafter, progressive ultrastructural injury to remaining nerve structures was evident. Within the first 2 years, the number of ICC-IM did not decline although ultrastructural injury was already present. Thereafter, loss of ICC-IM occurred unrelated to duration of disease. Damage to ICC-IM appeared unrelated to nerve injury. A significant MC infiltration was observed in the musculature; the number of MC was positively related to the persistent number of ICC-IM. Mast cell formed close contacts with ICC-IM and piecemeal-degranulation occurred towards ICC-IM. In conclusion, injury to ICC-IM in achalasia is variable, but not related to duration of disease and injury to nitrergic nerves. MC are prominent and form close functional contact with ICC-IM which may be responsible for their relatively long survival.

Abstract
BACKGROUND This study aimed to evaluate the long-term impact of laparoscopic Nissen fundoplication on esophageal motility in patients with preoperative esophageal dysmotility. METHODS This study prospectively followed 580 patients who underwent laparoscopic Nissen fundoplication between 1992 and 1999. Esophageal manometry, 24-h pH monitoring, and symptom score assessment were performed before surgery, then 6 months, 2 years, and 5 years after surgery. Preoperatively, 533 of the patients (93.5%) had normal esophageal contractile pressure (group 1), whereas 38 of the patients (6.5%) had reduced contractile pressure (<30 mmHg) (group 2). RESULTS Esophageal contractile pressures increased significantly in the patients with low preoperative values, whereas it remained unchanged in the patients with normal preoperative contractile pressures. Both groups reported a significant reduction in the dysphagia symptom score after surgery. CONCLUSION Nissen fundoplication produces a significant long-lasting increase in esophageal contractile pressures in patients with preoperative esophageal dysmotility (i.e., contractile pressure lower than 30 mmHg). Preoperative esophageal dysmotility is therefore not a contraindication to laparoscopic Nissen fundoplication.

Abstract
BACKGROUND Symptoms of gastroesophageal reflux disease (GERD) are experienced by up to 85% of pregnant women. Some young women on maintenance proton pump inhibitor (PPI) treatment are choosing surgery to stop their medical treatment and avoid severe symptoms during pregnancy. There are no reports describing the effect of pregnancy on the long-term efficacy of laparoscopic Nissen fundoplication. The aim of this study was to evaluate the effect of pregnancy on the efficacy of laparoscopic Nissen fundoplication. METHODS This study surveyed 146 women of childbearing age with proven GERD who had undergone laparoscopic Nissen fundoplication from 1992 through 2002. The patients who became pregnant (group 1) were compared with those who did not (group 2). RESULTS The study focused on 25 patients who became pregnant after surgery. Of these patients, 40% (n = 10) had chosen surgery as a way to discontinue PPI treatment before pregnancy. The mean time from laparoscopic Nissen fundoplication to pregnancy was 25.9 +/- 4.6 months. A total of 19 patients (76%) had no reflux symptoms, whereas 5 (20%) required antacids during pregnancy. One patient (4%) experienced an acute intrathoracic stomach migration during her pregnancy and required emergency open surgery, which resulted in the loss of her fetus. After pregnancy, six patients (24%) had recurrence of GERD symptoms, and three (12%) required a redo fundoplication. The higher rate of GERD recurrence (24% vs 16.7%) and redo surgery (12% vs 4%) in group 1 did not reach statistical significance, but showed a definite trend. CONCLUSION For most patients, laparoscopic Nissen fundoplication is effective in controlling GERD symptoms during and after pregnancy.

Abstract
Multiple reports have outlined the potential benefits of the laparoscopic approach to colon surgery. Recently, randomized control trials have demonstrated the safety of applying these techniques to colorectal cancer. This study examined the long-term follow-up assessment of patients after laparoscopic colorectal cancer resections and compared them with a large prospective database of open resections. A total of 231 resections were performed for adenocarcinoma of the colon or rectum between 1992 and 2004. Of these 231 resections, 93 were rectal (40.3%) and 138 were colonic (59.7%). A total of 8 (3.2%) of the resections were performed as emergencies, and 27 (11.7%) were converted to open surgery. The mean follow-up period was 35.84 months (range, 0-132 months). The disease recurred in 51 of the patients (22.1%) before death, involving 14 (6.1%) local and 37 (16%) distant recurrences. Only two patients had wound recurrences (0.8%), and both patients had widespread peritoneal recurrence at the time of diagnosis. The overall survival rate was 65.3% at 60 months and 60.3% at 120 months. The disease-free survival rate was 58% at 60 months and 56% at 120 months. Laparoscopic techniques can be applied to a wide range of colorectal malignancies without sacrificing oncologic results during a long-term follow-up period.

Abstract
BACKGROUND To date, few studies have examined the effect of morbid obesity on the outcome of laparoscopic antireflux surgery and results have been conflicting. The aim of this work was to study the outcome of laparoscopic Nissen fundoplication (LNF) in patients with body mass index (BMI) >or= 35. METHODS We prospectively followed 70 patients (15 men, 55 women) with a proven diagnosis of gastroesophageal reflux disease (GERD) and a mean BMI of 38.4 +/- 0.5 (range, 35-51) who underwent LNF. All patients underwent 24-h pH study, esophageal manometry, upper gastrointestinal (GI) endoscopy, and GERD symptom score before and 6 months after LNF. Surgical outcomes were compared to those of 70 sequential nonobese patients (BMI < 30) who also underwent LNF. RESULTS LNF was completed laparoscopically in 69 of 70 patients in the morbidly obese (MO) group and in all 70 patients in the normal-weight (NW) group. The mean operative time for the MO group was not significantly longer than that for the NW group (55.9 +/- 2.3 min vs 50.0 +/- 2.1 min), but the mean length of stay was significantly longer (3.17 +/- 0.2 days vs 2.2 +/- 0.1 days, p < 0.0001) in the MO group. There was one postoperative complication (a transhiatal herniation of the stomach) in the morbidly obese group. In both patient groups, LNF resulted in a significant increase in lower esophageal sphincter (LES) pressures. This was associated with a significant decrease in percent acid reflux in 24-h testing and a significant improvement in GERD symptom score in both groups, although patients in the MO group had a significantly higher mean reflux symptom score after surgery than did those in the NW group. After a mean follow-up of 41.6 +/- 2.9 months, one patient in the MO group required reoperation and one proton pump inhibitor therapy (PRN PPI), as required. CONCLUSIONS Morbid obesity does not adversely affect the outcome of LNF. The conversion rate is low when performed by an experienced surgeon.

Abstract
Certain technical features of laparoscopic Heller cardiomyotomy (LHM) remain controversial, including the extent of the myotomy and the indication for an antireflux procedure. We completed a retrospective chart review of all patients who underwent LHM for achalasia at 1 tertiary care institution to review our institutional experience with LHM without an antireflux procedure. Forty patients underwent a LHM performed by 2 surgeons, 65% of whom had previous medical management (Botox: 12 patients, LES dilatation: 14). The operating time was significantly increased in patients with Botox injections (98.3 vs. 71.1 minutes, P = 0.005). There were 3 intraoperative complications (mucosal injury in 3 patients, 2 had Botox injections). Postoperative evaluation demonstrated a mean dysphagia score of 0.2, a mean heartburn score of 3.2, and a mean LES pressure of 6.32 mm Hg. Thirty-two patients are maintained on acid-suppressing medications with good control of reflux symptoms. LHM without an antireflux procedure achieves excellent clinical outcomes in most patients with achalasia regardless of previous medical management. Previous medical management may present a greater technical challenge and may place patients at increased risk of mucosal injury.

Abstract
BACKGROUND Of patients with chronic cough, 21% have GERD. Up to half of these patients may not respond adequately to medical, but the long-term results of antireflux surgery for cough is unknown. METHODS A total of 905 patients (209 with respiratory symptoms, mainly cough) underwent laparoscopic Nissen fundoplication. Preoperatively patients underwent esophageal motility studies, 24-h pH monitoring, and symptom evaluation using a validated scale. Of eligible patients, 81% were followed at 6 months, 73% at 2 years, and 60% at 5 years. RESULTS Before surgery, 83% of respiratory patients (RP) and 51% of nonrespiratory patients (NRP) had cough. RP had higher cough scores ( p < 0.0001), but improvement in cough compared to baseline was similar in the RP and NRP ( p = 0.1105 at 6 months, 0.4206 at 2 years, and 0.1348 at 5 years). Cough improved in 83% at 6 months, 74% at 2 years, and 71% at 5 years. CONCLUSIONS Laparoscopic Nissen fundoplication is successful in the long-term control of GERD-related cough, even in patients who fail medical therapy.

Abstract
BACKGROUND To date, there has been no objective evidence for the effectiveness of laparoscopic redo fundoplication. We therefore reviewed our experience and based our analysis on a number of objective parameters. METHODS We prospectively followed 28 consecutive patients (five men and 23 women; mean age, 48.64 +/- 2.57 years) who required redo fundoplication. These patients were part of a series of laparoscopic Nissen fundoplications done between 1992 and 2001. The indications were recurrent symptoms of gastroesophageal reflux disease (GERD) (21 patients), acute herniation of the wrap (three patients), and chronic paraesophageal hernia (four patients). A diagnosis of recurrent GERD was based on endoscopy, 24-h pH study, manometry, and symptom score evaluation. A diagnosis of paraesophageal and acute herniation was based on contrast swallow studies and/or gastroscopy. RESULTS Twenty-six redo fundoplications were completed laparoscopically; two were converted to open. The mean operative time was 55.43 +/- 3.81 min. There were no intraoperative complications. The mean hospital stay was 3.0 +/- 0.35 days. Postoperative complications included postoperative pneumonia in one patient. Two patients from the laparoscopic group required a third operation-one for acute herniation of the redo wrap, which was fixed laparoscopically, and the other for acute recurrent paraesophageal hernia, which was fixed via an open transthoracic approach. The mean follow-up after revision is 25.14 +/- 3.48 months, with a significant decrease in acid reflux from 5.01% +/- 0.99 to 0.48% +/- 0.23 ( p < 0.0001), a significant decrease in symptom score from 28.96 +/- 2.93 to 10.75 +/- 2.61 ( p < 0.0001), and a small but significant increase in lower esophageal sphincter (LES) pressure from 13.71 +/- 1.79 to 16.69 +/- 1.50 ( p = 0.04). CONCLUSIONS Laparoscopic redo fundoplication is technically feasible and clinically effective over a 2-year objective follow-up. Conversion and complication rates are low.

Abstract
Laparoscopic fundoplication (LF) has been shown to be effective in treatment of patients with gastro-esophageal reflux disease (GERD) requiring long-term medical therapy. Its effectiveness in patients with poor response to proton pump inhibitors (PPIs) has been questioned. We prospectively followed 445 patients with proven GERD inadequately controlled on PPI (up to 120 mg/day) and 274 GERD patients with good response to PPIs (20-120 mg/day) after LF. Patients in both groups underwent 24 h pH testing, esophageal manometry, symptom score evaluation, and quality-of-life (QOL) assessment (SF-36) before and at 6 months, 2 years, and 5 years after surgery. LF was associated with a marked improvement in percentage acid reflux, lower esophageal sphincter pressure, and symptom control in both groups of patients; however, the poor responders to PPIs also had a significant improvement in both physical and mental health component of the QOL assessment. Laparoscopic fundoplication provides an excellent symptom control for GERD patients, even those who have responded inadequately to large doses of PPIs. GERD patients who respond poorly to PPI therapy have significantly lowered physical and mental health QOL scores. Laparoscopic fundoplication in this group of patients leads to marked improvement of both components of QOL by 2 years after surgery.

Abstract
BACKGROUND Transient lower esophageal sphincter relaxation (TLESR) is the most common mechanism underlying gastroesophageal reflux disease (GERD), causing 70% to 100% of the reflux episodes in normal subjects and 63% to 74% of the reflux episodes in patients with reflux disease. This study aimed to evaluate the effect of laparoscopic Nissen fundoplication on TLESR in patients with proven GERD. METHODS We prospectively followed 73 consecutive patients (13 men and 60 women; mean age, 43.7 +/- 1.72 years) with proven diagnosis of GERD and reported TLESRs found during a 40-min esophageal manometric study. These patients had repeat testing 6 months after undergoing laparoscopic Nissen fundoplication. RESULTS Laparoscopic Nissen fundoplication increased the basal and nadir lower esophageal sphincter (LES) pressure and significantly reduced the number of TLESRs during the manometric study. No patients after surgery exhibited TLESR with nadir less than 2 mmHg. However, 8 of the 73 patients (11%) exhibited TLESR to a nadir exceeding 50% of basal pressure (mean nadir, 5.0 +/- 1.07 mmHg). CONCLUSIONS The number of TLESRs is reduced significantly by antireflux surgery. Even accounting for increased basal and nadir pressures, the incidence of TLESR is reduced, suggesting that there may be additional mechanisms involved in this process.

Abstract
Glucagon-like peptide-1 (GLP-1) modulates glucose levels following a meal, including by inhibition of gastric emptying and intestinal transport. Intra-arterial injection of GLP-1 into the gastric corpus, antrum, or pylorus of anesthetized dogs had no effect on the contractile activity of the resting or neurally activated stomach. GLP-1 injected intra-arterially inhibited intestinal segments when activated by enteric nerve stimulation but not by acetylcholine. Isolated ileum segments were perfused intra-arterially, instrumented with strain gauges to record circular muscle activity and with subserosal electrodes to stimulate enteric nerves. GLP-1 caused concentration-dependent inhibition of nerve-stimulated phasic but not tonic activity. This was absent during TTX-induced activity and partly prevented by N(G)-nitro-L-arginine. Exendin-(9-39), the GLP-1 antagonist, had no intrinsic activity and did not affect the actions of GLP-1. Capsaicin mimicked the effects of GLP-1 and may have reduced the effect of subsequent GLP-1. GLP-1 may mediate paracrine action on afferent nerves in the canine ileal mucosa using an unusual receptor.

Abstract
BACKGROUND The objective of this study was to assess the integrity of the vagal nerve afferent pathways in patients with gastroesophageal reflux disease (GERD). METHODS Seven GERD patients (4 males and 3 females, mean age 39 +/- 8 years) were studied. Twelve healthy volunteers (11 males and 1 female, mean age 32 +/- 8 years) were used as the control group. Cortical evoked potentials were measured. Electrical stimulation of the esophageal mucosa was performed through a custom-built device. Latencies and N2/P2 amplitude were measured. RESULTS Reproducible cortical evoked potentials were obtained from all subjects. The stimulation threshold for GERD patients to electrical esophageal stimulation was 5.1 +/- 1.5 mA compared to 7.8 +/- 2.0 mA in healthy volunteers (p <0.05). There was no difference in peak latencies or N2/P2 amplitude between GERD patients and controls. CONCLUSIONS GERD patients have a normal vagal nerve function, but they exhibit a decreased threshold for esophageal perception. The mechanism responsible for increased esophageal sensitivity observed in GERD patients is still undetermined and warrants further study.

Abstract
BACKGROUND Most patients with cough and gastroesophageal reflux disease (GERD) improve on medical treatment with proton pump inhibitors (PPI). Nonresponders may be considered for antireflux surgery, but the selection of patients is difficult. METHODS We have performed laparoscopic Nissen fundoplications (LNF) in 677 patients. Of these patients, 81% have undergone 6-month follow-up assessment with 24-h pH testing, esophageal manometry, symptom scores, and quality-of-life scores. RESULTS LNF controlled heartburn in 93% and improved cough in 81%. Stepwise multiple regression showed that the preoperative cough score (r = 0.620, p <0.0001) and change in cough on and off PPI (r = 0.296, p = 0.0002) predicted improvement after surgery. A positive result on a randomized acid infusion test was associated with a greater improvement in cough after surgery (p = 0.0243). CONCLUSION An acid infusion test and assessment of cough on and off PPI may be useful preoperative tools for the selection of patients with cough for LNF.

Abstract
OBJECTIVE To evaluate the prevalence and possible contributing factors to postprandial bloating in patients having chronic gastroesophageal reflux disease (GERD) before and after laparoscopic Nissen fundoplication. DESIGN A prospective cohort study. SETTING A tertiary care teaching hospital. PATIENTS Five hundred and seventy-eight patients with proven GERD. INTERVENTION Laparoscopic Nissen fundoplication. OUTCOME MEASURES Symptom severity scores for postprandial bloating and dysphagia, esophageal motility and 24-hour pH measurement before and at 6 months, 2 years and 5 years after laparoscopic Nissen fundoplication. RESULTS Of the 598 patients, 436 (73%) reported some postprandial bloating before the procedure. The symptom score for bloating significantly improved after surgery (p < 0.0001). There were no significant differences in the lower esophageal sphincter basal pressures or 24-hour pH scores between those who reported improvement or worsening of their postprandial bloating. At 6 months after surgery, 54% of patients experienced postprandial bloating; of these, 49% reported improvement, 21% reported worsening and 30% reported no change in bloating symptoms compared with the preoperative state. Of the patients who reported worsening of postprandial bloating 6 months after surgery, 86 were reassessed 2 years after surgery and 71% reported improvement of this symptom over this time interval. CONCLUSIONS Bloating is a common symptom in patients who suffer from chronic GERD. Laparoscopic Nissen fundoplication lessens the severity of this symptom in most patients. In a small subgroup of patients, antireflux surgery may exacerbate the bloating, but this improves over time.

Abstract
BACKGROUND Gastroesophageal reflux (GER) is commonly associated with chronic cough and asthma, but there is little or no information on the nature of any associated airway inflammation. OBJECTIVE To observe whether the association with GER worsens airway inflammation in patients with chronic cough or asthma. PATIENTS AND METHODS The airway inflammatory indexes in induced sputum and exhaled air were examined in a cross-sectional study of 11 patients with cough and GER, nine patients with mildly symptomatic asthma and GER, nine patients with mildly symptomatic asthma without GER and nine normal, healthy control subjects. GER was shown objectively by 24 h ambulatory pH recording. RESULTS The sputum total cell count, the proportion of neutrophils and macrophages, and the fibrinogen level were normal in all four groups, with no significant differences among the groups. The sputum eosinophil and metachromatic cell percentages, and eosinophil cationic protein levels were normal in patients with cough and GER. They were significantly increased in patients with asthma compared with healthy subjects (P<0.01) and patients with cough (P<0.01), but were not different between groups with and without GER. Exhaled nitric oxide levels showed similar results (P<0.01). The correlations between the number of episodes of reflux and the proportion of sputum eosinophils, neutrophils or exhaled nitric oxide were modest but not significant. CONCLUSIONS GER, when associated with cough or mildly symptomatic asthma, does not cause or aggravate existing airway inflammation as measured by induced sputum cell counts and fibrinogen level, or by exhaled nitric oxide.

Abstract
The purpose of this study was to establish the reproducibility, validity, and responsiveness of a symptom questionnaire to assess patients with gastroesophageal reflux disease (GERD). A total of 300 patients with GERD completed questionnaires before and 6 months after laparoscopic Nissen fundoplication. Forty-six GERD patients who continued on omeprazole served as controls. Lower esophageal sphincter pressure, 24-h pH, and quality of life (SF36) were measured at baseline and follow-up. Reproducibility was calculated as an intraclass correlation coefficient (ICC) from a repeated-measures analysis of variance on symptom scores (SS) on two consecutive days. Validity was established by correlating SS with 24-h pH and SF36 scores. Responsiveness was calculated as the the ratio of the mean paired difference in score in the surgical group to the within-subject variability in control subjects. Reproducibility was very high, as revealed by an ICC of 0.92. Strong correlations between SS and SF36 scores at baseline and after surgery demonstrated high cross-sectional validity. Correlation between change in SS and change in pH, SF36 pain, general health, and physical health scores demonstrated longitudinal validity. The mean (95% confidence interval) paired differences in SS were 25.6 (23.7, 27.5) in the study and 2.0 (-3.2, 7.3) in the control groups, and the responsive index was 1.0. The estimated minimally important clinical difference was 7. We conclude that the symptom score is a reproducible, valid, and responsive instrument for assessing symptoms caused by GERD.

Abstract
Laparoscopic inguinal herniorrhaphy has become a popular operation for the treatment of inguinal hernia. However, injury and entrapment of the cutaneous nerves of the lumbar plexus by the staples or tackers used for mesh fixation have been described. Laparoscopic removal of the staples or tackers in the inguinal region has been attempted with variable success. The success of the laparoscopic approach for removal of helical tackers in particular is sometimes limited by the fact that the offending tackers are deeply embedded in the preperitoneal tissues and not readily located with a simple laparoscopic view. The authors report a case in which fluoroscopy was used to help identify tackers that could not be visualized laparoscopically. The neuralgia disappeared after successful removal of the offending tackers with no neurologic deficit. Liberal use of fluoroscopic guidance in the laparoscopic removal of helical tackers in similar cases is recommended.

Abstract
BACKGROUND Laparoscopic bowel resection is an alternative to open surgery for patients with Crohn's disease requiring surgical resection. The present report describes a seven-year experience with the laparoscopic treatment of Crohn's disease compared with the open technique in a tertiary Canadian centre. PATIENTS AND METHODS A retrospective analysis of 61 consecutive patients undergoing elective resection for Crohn's disease was carried out between October 1992 and June 1999. This analysis included 32 laparoscopic resections (mean age 33 years) and 29 open resections (mean age 42 years). Patient demographics were compared, as well as short and long term outcomes after surgery (mean follow-up 39 months). RESULTS Patients in the laparoscopic group were younger and had fewer previous bowel surgeries than patients who had open resections. Indications for surgery and operative times were similar between the groups. Patients who underwent laparoscopic resections required fewer doses of narcotic analgesics. The resumption of bowel function after surgery, and tolerance of a clear liquid and solid diet was quicker in the laparoscopic group. Patients who underwent laparoscopic resections had significantly shorter hospital stays than those who underwent open resections. Fifteen patients (48.4%) in the laparoscopic group experienced recurrence of disease compared with 13 patients (44.8%) in the open group. In both groups, the most common site of recurrence was at the anastomosis. The disease-free interval was the same length for both groups (23.9+/-17.3 months for the laparoscopic resection patients compared with 23.9+/-20.2 months for the open resection patients; P=1.00). CONCLUSIONS Laparoscopic resection for Crohn's disease can be performed safely and effectively. Quicker resumption of oral feeds, less postoperative pain and earlier discharge from hospital are advantages of the laparoscopic method. No differences in the recurrence rate or the disease-free interval were noted.

Abstract
PURPOSE To compare the outcome after laparoscopic versus open resection for colorectal adenocarcinoma. METHODS A retrospective cohort analysis of all patients undergoing elective resection for colorectal adenocarcinoma between November 1992 and June 1999 at a university-affiliated hospital. These included 219 open (mean age, 68.3 years) and 98 laparoscopic (mean age, 70.3 years) resections. Data from converted cases (n = 12) were included in the laparoscopic group using the intention-to-treat principle. RESULTS Operative time, lymph node yield, resection margins and postoperative morbidity and mortality were similar between laparoscopic and open technique. Parenteral analgesic use was less in the laparoscopic group (laparoscopic, 2.7; open, 3.2 days; P = 0.021). Time to first flatus (laparoscopic, 1.8; open, 3 days; P < 0.0001) and first bowel movement (laparoscopic, 3.5; open, 4.9 days; P < 0.0001) was shorter in the laparoscopic group. Resumption of an oral liquid diet (laparoscopic, 2.1; open, 4 days; P < 0.0001) and solid diet (laparoscopic, 5.2; open, 7.1 days; P < 0.0001) was also quicker in the laparoscopic patients. Length of hospitalization was significantly shorter in the laparoscopic patients (laparoscopic, 6.9; open, 10.9 days; P < 0.001). There were less minor complications in the laparoscopic group (laparoscopic, 11.2; open, 21.5 percent; P = 0.029) but no difference in major complications or perioperative mortality. Recurrence, disease-free and overall survival were similar between the two groups. No port site recurrences occurred in the laparoscopic group but there were three wound recurrences in the open group. CONCLUSIONS Laparoscopic resection for colorectal cancer can be performed safely and effectively in tertiary centers. Earlier discharge from hospital, quicker resumption of oral feeds and less postoperative pain are clear advantages. No adverse effect on recurrence or survival was noted, but results of prospective, randomized trials, currently underway, are needed before laparoscopic resection for colorectal cancer becomes the standard of practice.

Abstract
The diagnostic properties of a "lipid index" of macrophages in induced sputum as a noninvasive marker of aspiration of acidic gastric contents were evaluated. In a cross-sectional study, 33 subjects (17 with symptoms suggestive of gastrooesophageal reflux) with normal chest radiographs and no symptoms of aspiration or sinus disease, underwent dual-channel 24-h ambulatory oesophageal pH recording and sputum induction. Oropharyngeal reflux, defined as at least one episode of a fall in pH to <4 at the upper oesophageal electrode, was considered indicative of aspiration of acidic gastric contents ("gold standard"). An index for the presence of intracellular lipid in sputum macrophages, detected by oil red O stain, was obtained. The sensitivity, specificity and predictive values of this "lipid index" were calculated. The "lipid index" could be calculated in 29 of 33 samples with high interobserver repeatability (intraclass correlation coefficient 0.96). Twenty subjects showed oropharyngeal reflux and nine did not. The median "lipid index" in subjects with oropharyngeal reflux (24.5) was significantly greater than that in those without reflux (1.0) (p<0.001). A "lipid index" of 7.0 had a sensitivity of 90%, a specificity of 89%, a positive predictive value of 95% and a negative predictive value of 80%. A "lipid index" of 7.0 in the macrophages of induced sputum is a good marker of oropharyngeal reflux.
