“…We used the data from the Iranian National Obesity Surgery cohort database [ 23 , 24 ]. In a retrospective cohort study design, we selected patients who had undergone bariatric surgery performed by a single surgeon from June 2009 to March 2019 and had at least 1 year of follow-up.…”

Introduction Multidisciplinary care after bariatric surgery is essential for long-term safety and optimal weight loss. However, many patients do not participate in routine postoperative follow-ups. We have explored the determinants of patients’ adherence to scheduled follow-up visits after bariatric surgery. Method A retrospective cohort study was performed on patients who underwent bariatric surgery from 2009 to 2019. Cohort participants with a proportion of attendance above the median were compared with those below the median in the first-year post-operation and the period after that. We assumed that the contribution of each predefined session to the overall attendance at eligible sessions is not equal. We weighted each predefined session by the proportion of attendance of all cohort members scheduled for that session. We then calculated the proportion of attendance for each individual at each period. Discriminatory logistic regression was used to identify factors separating adherers from non-adherers. Results We followed 5245 patients who underwent bariatric surgery for up to 10 years. The median follow-up was 2 years. Patients with the following characteristics were more likely to comply with the postoperative attendance schedule: female sex, older age, higher body mass index at the first visit, non-smoker, readmission after surgery, being operated in a general hospital, and one-anastomosis gastric bypass (OAGB) or Roux-en-Y gastric bypass (RYGB) surgery type. Comorbidities did not significantly affect patients’ adherence to the predefined follow-up schedules. Conclusion Younger male smokers are more likely non-adherers. Patients with comorbidities are not at an increased risk of missing predefined postoperative follow-up visits.

Purpose Obesity has become a global health concern, associated with decreased quality of life and life expectancy. Although bariatric surgery has many benefits (e.g., substantial and durable weight loss, amelioration of comorbidities, and improvement in functionality), its patient attrition rate is relatively high. Therefore, we aim to assess the causes of withdrawal from our program. Materials and Methods We interviewed patients who dropped out of our bariatric surgery program between January 2016 and December 2021. A total of 1999 patients were eligible for bariatric surgery during this period, and 255 patients withdrew from the program. We interviewed patients over the phone to find out the reason for withdrawal. We divided participants into two groups: dropouts before and during the COVID-19 pandemic. Several options explaining the reason for leaving the program were presented to the patients to choose from. Results The number of patients who withdrew from the program before and during the COVID-19 pandemic was 135 (8.9%) and 120 (25.2%), respectively. Before the COVID-19 pandemic, most patients (49.1%) stated that the long waiting time was the cause of withdrawal. Even though during the COVID-19 pandemic, the main causes of attrition were the fear of contracting the disease and COVID-19 infection; the most common reason unrelated to COVID-19 was still the long preoperative preparation. Conclusion Long waiting time was the most common cause of patient attrition before bariatric surgery. To reduce the attrition rate, more studies should be conducted to find an optimized waiting time before bariatric surgery. Graphical Abstract

“…The inclusion criteria comprised a minimum age of 18 years and BMI > 40 kg/m 2 or BMI > 35 kg/M 2 and obesity-related comorbidities. The data extracted from the Iran National Obesity Surgery Database (INOSD) [ 9 ] included comorbidities and demographic and anthropometric information. Symptoms of DS were recorded through phone interviews with eligible candidates using the early dumping symptom rating scale (DSRS) within 1 year after the operation [ 10 ].…”

Purpose The present research was conducted to evaluate the effect of the severity of dumping syndrome (DS) on weight loss outcomes after Roux-en-Y gastric bypass (RYGB) in patients with class III obesity. Methods The present retrospective cohort study used the dumping symptom rating scale (DSRS) to evaluate the severity of DS and its correlation with weight loss outcomes in 207 patients 1 year after their RYGB. The patients were assigned to group A with mild-to-moderate DS or group B with severe DS. Results The mean age of the patients was 42.18 ± 10.46 years and their mean preoperative BMI 42.74 ± 5.59 kg/m2. The total weight loss percentage (%TWL) in group B was insignificantly higher than that in group A, but besides that was not significantly different in the two groups. Conclusion The present findings suggested insignificant relationships between the presence and severity of DS after RYGB and adequate postoperative weight loss.
