Abstract
Background: This study aims to evaluate the outcomes and late complications of open Roux-en-Y gastric bypass surgery in the treatment of morbid obesity.
Methods: Over a 15 year-period between May 1997 and May 2012, we reviewed our experiments with 39 patients who underwent open gastric bypass for morbid obesity. The weight of the patient and surgical complications were recorded. Ideal weight, body mass index, weight loss and excess weight loss were calculated.
Results: The follow up period ranged from 6 to 180 months with a mean of 100 months after operation. Average weight loss was 3.9 and 0.28 kg per month during the first and second years after operation weight loss was slower from the third year on-wards. Weight loss generally was stabilized between 12 and 18 months after operation. Only one patient (2.6%) had a weight loss failure criterion. Concomitant condition ex-isted in 14 patients (48.2%) of our series. These included hypertension in 3 cases (10.3%) that was resolved in 100%, diabetes mellitus in 4 (13.7%) that was resolved in 75%, cholelithiasis in 7 cases (24.1%) that was resolved by cholecystectomy during the operation. There was no early postoperative death. Early complications occurred in 2 patients (5.1%), including pulmonary embolism (2.6%) and gastrointestinal bleeding (2.6%). The late complications occurred in 7 patients (17.9%) involved 2 patients with anastomotic stricture at the gastrojejunostomy (5.1%), One patient with symptomatic cholelithiasis (2.6%), three patient with anemia (7.7%), and one patient had Wernicke ’s disease who died of this complication (2.6%).
Conclusion: The results of the study showed that the open Roux-en-Y gastric bypass surgery is an effective procedure in the treatment of morbid obesity with minimal late complications.

Abstract
Background: The vertical gastric plication technique leads to poor long-term outcomes and is associated with intolerable reflux, dysphagia, or weight gain in a high percentage of patients. Therefore, in this study, the therapeutic results of two methods with and without plication of the distal part of the stomach in gastric bypass surgery in patients with morbid obesity were compared.
Methods: In this clinical trial randomized single-blind study, 40 patients with morbid obesity who were referred to one of the hospitals affiliated with Jundishapur University of Medical Sciences in Ahvaz during March 2020-February 2021, were randomly divided into two groups: with plication of the distal part of the stomach (n=20) and without plication of the distal part of the stomach (n=20) in Roux-en-Y gastric bypass surgery. Weight loss rate, complications related to surgery, outcomes and satisfaction of patient were noted and followed up for one year.
Results: The mean percentage of weight loss at different times did not show a significant difference between the two groups (p>0.05). The length of hospitalization after surgery was significantly less in the distal gastric plication group (p=0.0001). During one year of follow-up, hypertension, diabetes, HLP, and reflux were well in the distal plication method but showed no significant difference (p>0.05). Satisfaction of the patients was more in the distal plication method and showed no significant difference (p>0.05). One year after the operation, the change of diet showed no significant difference in the two groups (p>0.05).
Conclusion: It looks that using the laparoscopic distal gastric plication method is an effective and safe method and is associated with early ideal weight loss, reduction of complications, and increase in satisfaction of patients with BMI>=35 kg/m2. No need to use a foreign body, stapler or bandage and the possibility of re-operation are the advantages of this technique.

Abstract
Background: Dumping syndrome is a common complication after bariatric surgery and can adversely affect patients’ quality of life, particularly in those with diabetes. Although gastric bypass has traditionally been associated with a higher risk of dumping syndrome, evidence comparing its frequency with sleeve gastrectomy remains inconclusive. This study aimed to compare the frequency of dumping syndrome following these two procedures in patients with morbid obesity.
Methods: This prospective cohort study was conducted from April 2021 to July 2022 at Sina Hospital in Tehran. A total of 90 patients with morbid obesity who met the indications for bariatric surgery were not randomly assigned to two treatment groups: gastric bypass (n = 45) and sleeve gastrectomy (n = 45). Baseline assessments included medical history, physical examination, review of medical records, and necessary specialist consultations (including endocrinology and cardiology). All patients’ data were recorded in the Sina Bariatric Surgery Registry Database. Following surgery, patients received standard postoperative care and were evaluated for symptoms of dumping syndrome at one and three months postoperatively using the validated Sigstad questionnaire. Statistical analyses were performed using SPSS software.
Results: The results showed no statistically significant differences between the two groups in terms of age group, gender, excess weight, preoperative BMI, final BMI, and history of diabetes prior to surgery (P-value > 0.05). The final weight was significantly higher in the sleeve gastrectomy group (P-value = 0.033). There were no significant differences in the frequency of early and late dumping syndrome related to the consumption of sweets and other foods between the two groups at the first and third postoperative months (P-value > 0.05). Early dumping syndrome following the consumption of sweets and bread was significantly more frequent among diabetic patients (P-value = 0.037 and P-value = 0.045, respectively).
Conclusion: The prevalence of dumping syndrome was similar in both sleeve and bypass groups. Weight loss over time was significant (P < 0.001) and did not differ between groups (P = 0.211). The syndrome was significantly more common in diabetic patients, highlighting the importance of careful postoperative care and dietary guidance.
