Purpose: After bariatric surgery, postoperative follow-up is important for evaluating long-term outcomes, such as successful weight loss and improvement of metabolic parameters. However, many patients are lost to follow-up within 1 year. This study aimed to identify the follow-up rate of bariatric surgery and predictive factors of loss to follow-up (LTF).
Materials and methods: We retrospectively reviewed the data of 61 patients receiving bariatric surgery for obesity (laparoscopic sleeve gastrectomy; LSG group) and 872 for early gastric cancer (EGC group) from November 2018 to July 2020 in a single center. After 1:1 matching, we compared the LTF rate. In the LSG group, we analyzed the factors associated with LTF. Additionally, we collected weight data in the LTF group by a telephone survey.
Results: By 1:1 matching, 47 patients for each group were identified. The LTF rates of the LSG and EGC groups were 34.0% (16 patients) and 2.1% (one patient), respectively (P=0.0003). In the LSG group, the LTF rate increased over the postoperative month. Of the patients, 29.5% who missed a scheduled appointment within one year comprised the LTF group. In the analysis, no significant factors associated with LTF were identified. The only factor with borderline significance was dyslipidemia with medication (P=0.094).
Conclusion: The LSG group demonstrated a high LTF rate, although adherence to follow-up was closely related to postoperative outcomes. Therefore, educating patients on the significance of follow-up is important. Particularly, continuous efforts to identify the associated factors and develop a multidisciplinary management protocol after bariatric surgery are necessary.

Introduction: Laparoscopic sleeve gastrectomy (LSG) is the commonest bariatric operation being performed in India and worldwide. There are many technical variations that are being practiced. This Delphi consensus was an Obesity and Metabolic Surgery Society of India (OSSI) initiative to standardize the surgical technique of LSG. Methods: Twenty bariatric surgeons were selected as experts based on their years of experience in LSG, overall patient volumes, publications, and the recommendations of the executive committee of OSSI, to vote on 26 statements regarding the surgical steps of LSG. The minimum cutoff for consensus was taken as 70%. Results: The committee achieved a consensus on 19 out of 26 statements in the first round. One question was sent for reconsideration and 3 were resent after modification. Finally, consensus was reached on 22 statements. The consensus was reached regarding the use of preoperative upper gastrointestinal endoscopy. 85.7% agreed on an antral length of 3–5 cm. 85.7% were in favor of dissecting the left crus of the diaphragm completely and 100% agreed on Roux-en y gastric bypass to be the procedure of choice in the presence of medically refractory gastroesophageal reflux disease with hiatus hernia. Most experts agreed that a calibration tube must be used during LSG and the recommended size was between 36 and 40 Fr. Ninety-five percent agreed that care must be taken to avoid narrowing at the incisura and also to stay away from the angle of His. 71.4% did not recommend any kind of staple line reinforcement and 71.4% recommended a postoperative leak test. Conclusion: This Delphi consensus is a step toward improving the quality of surgical outcomes of LSG in India. This document has attempted to establish technical specifications of performing LSG. This will in turn help to maximize the reliability, standardization, and safety of the procedure until more robust studies are published.

Aim: The aim of this study was to assess the safety and short-term effectiveness of metabolic surgery (MS) in nonobese diabetic patients. Methods: Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement was used in this systematic review. The search for evidence was performed in the Medline (PubMed), Embase, Cochrane (CENTRAL), LILACS, and ClinicalTrials.gov databases from the inception to February 2023. The main eligibility criteria were nonobese adults (body mass index [BMI] <30 kg/m2) with type 2 diabetes mellitus (T2DM) undergoing MS. T2DM remission rate, glycemic parameters, and weight loss were measured before and after surgery. Complication rate was also described. Outcomes were aggregated and the quality of evidence was sorted. Heterogeneity was assumed when I2 >50%. The random-effects model was used to perform a proportional meta-analysis. Results: Twenty-one studies were included (n = 835). The overall rate of diabetes remission was 50.1% (95% confidence interval [CI] = 43.8%–56.1%; P = 0.993; I2 = 92%). The mean reduction of glycated hemoglobin and fasting glucose was 2.42% (95% CI = 1.91%–2.93%; P < 0.00001; I2 = 89%) and 70.60 mg/dL, respectively. A drop of 3.34 points (95% CI = 1.59–5.09; P < 0.0002; I2 = 95%) was observed in the HOMA-IR, and the mean postprandial glycemia was 123.27 mg/dL. No marked weight loss was observed (−3.80 kg/m2 in BMI; 95% CI = 2.70–4.91; P < 0.00001; I2 = 95%). There was no postoperative mortality, and the overall postoperative complication rate was about 12%. The certainty of evidence was low or very low. Conclusion: MS could be effective in the surgical approach of nonobese diabetic patients, but further long-term, more robust studies are needed to strengthen the evidence.

Correlation between bariatric surgery (BS), weight loss, and alleviation of anxiety symptoms has been assessed frequently. Research indicates a rather positive effect on anxiety symptoms for the first 3 years after surgery. Beyond this time frame, alleviation of symptoms becomes less apparent. The aim of this study was to investigate the connection between anxiety and BS based on the following research question: does BS lead to an alleviation of their anxiety symptoms in adults with morbid obesity and anxiety symptomatology? The basic mechanism underlying this study was a comprehensive literature search in PubMed and PsycINFO, combining search terms for “anxiety” with “bariatric surgery” related terms. The data set resulting from this search was assessed for relevant studies, which were the basis for the following narrative literature review. A set of 30 studies, 24 prospective cohort studies, and 6 literature reviews met inclusion criteria.The studies included 2228 participants (81% female). At baseline, mean age was 41.4 years and mean body mass index (BMI) was 47 kg/m2. The mean BMI at the end of the studies was 34 kg/m2. Different BS techniques were used for weight loss. A trend for change in anxiety at different time points postsurgery seems to exist. No clear statement can be made about a correlation between weight loss and alleviation of anxiety symptoms. Some studies found a significant correlation between the two parameters for up to 4 years; however, just as many studies found no correlation. The type of weight loss surgery utilized does most likely not determine the effect on anxiety symptoms. BS should not be thought of as a therapy method for anxiety.

Objective: The objective of the study is to evaluate the effect of very low-calorie diet (VLCD) on postbariatric surgery (BS) patients with weight regain (WR). Methods: This is a prospective, randomized, controlled, interventional clinical trial. The sample selection for the study was performed on the basis of prepared inclusion and exclusion criteria. Structured phone calls were made to all the subjects in which baseline information such as body weight and height were asked through which body mass index (BMI) was calculated to check the eligibility. A sample size of 40 subjects including both males and females with >10% gain of nadir weight after 2 years of BS with a current BMI of ≥30 kg/m[2] was selected. Two standardized VLCD plans for 4 weeks each were prescribed to them. A close supervision of selected subjects was done regularly through structured weekly calls, outpatient department follow-ups, and support group meets. The statistical analysis was done to find the average weight loss (WL) and change in body fat percentage over 8 weeks. Results: The mean average age of the sample was 45 ± 9.45 years among which 12 were male and 28 were female. The sample size was under the inclusion criteria with >10% WR after 2 years of BS. In this sample, the average total body WL after BS was found to be 47.3 kg. Postoperative average WR in the selected sample was 10.3%. After the follow-up period of 8 weeks of VLCD, an average WL of 3.66 kg (3.76%) along with a body fat percent loss of 2.58% was observed. It was also noted that the WL in the initial weeks was comparatively higher than that in the later weeks. An average WL in the first 4 weeks was 2.36 kg (2.42%) and average WL in the next 4 weeks was 1.32 kg (1.35%). Conclusion: VLCD is effective but long-term effects need to be seen. There have been no such Indian studies before this, and hence, more such studies need to be done.

Introduction: Bariatric surgery is an accepted treatment worldwide for patients with obesity due to its proven metabolic effects. However, there are variations worldwide in clinical criteria that must be met to qualify for surgery. This study aims to explore globally established practice and opinions on preoperative workup for bariatric surgery. Materials and Methods: A review of literature and international guidelines was performed by a multidisciplinary team and used to develop an online questionnaire survey. This was distributed to bariatric professionals electronically. Results: Two hundred and forty-four bariatric health-care professionals from 224 medical centers across 57 countries completed the survey. The majority of respondents were surgeons (67.2%), and the remainder were other multidisciplinary professionals. Over half of medical centers were public hospitals (50.8%), with most performing over 200 procedures per year (30.3%). Only 68.4% (n = 167) of respondent hospitals used recognized referral guidelines; however, 81.9% felt that there should be written referral criteria (P < 0.001). In 71.3% (n = 172) of respondent units' patients underwent a Medical Weight Management Programme (MWMP) as part of their preparation for surgery. Significant differences were identified worldwide in the criteria used to determine progression to surgery (P < 0.001), time spent in MWMP prior to surgery (P < 0.001), and the roles of members forming the bariatric multidisciplinary team (P = 0.006). Conclusion: This study has identified significant variation in global bariatric surgery practices and highlights the responsibility that societies such as the International Federation for the Surgery of Obesity and Metabolic Disease (IFSO) and the Upper Gastrointestinal Surgery Society have in promoting universal clinical guidelines.

Introduction: Variations in cultural practices, diet, socioeconomic factors, genetics, and procedure selection have a potential impact on nutritional outcomes after bariatric surgery. There are no updated guidelines from India on clinical practice on the nutritional management of patients undergoing bariatric surgery. This is the first attempt to have a consensus on the subject. Methods: An expert committee was constituted which voted for three rounds on 20 statements/questions based on a Delphi method. Results: There was consensus regarding preoperative screening of hemoglobin, packed cell volume, albumin, iron, ferritin, Vitamin D, Vitamin B12, preoperative weight loss, postoperative prophylactic protein supplementations, therapeutic supplementation of iron, B12, and Vitamin D, postoperative testing, and frequency of follow-up visits. Experts did not agree on the routine preoperative testing of serum folate and thiamine. There was no consensus on lifelong supplementation with bariatric formulation, difference of supplementation dosages for Roux-en-Y gastric bypass and one anastomosis gastric bypass, or postponement of surgery pending correction of nutritional deficiencies. Conclusion: We need a better-quality regional data to formulate guidelines that can provide evidence-based guidance for the clinical practice.

Aim: The aim is to assess the long- and very long-term rate of unfavorable outcomes associated with the laparoscopic adjustable gastric band (LAGB) in morbid obesity. Methods: The Preferred Reporting Items for Systematic Reviews and Meta-analyses statement was used in this systematic review. The search for evidence was performed in the MEDLINE (PubMed), EMBASE, LILACS, Clinical Trials, and Google Scholar databases from the inception to October 2021. The main eligibility criteria were obese adult undergoing LAGB, unfavorable outcomes, and a minimum follow-up of 4 years. Outcomes were aggregated using the Comprehensive Meta-Analysis software for noncomparative studies, and the quality of evidence was sorted. Heterogeneity was assumed when I2 >50%. Because of expected differences among retrieved studies and several uncontrolled variables, the random-effects model was used to perform a proportional meta-analysis. Results: Data on 23,916 unfavorable outcomes were extracted from 28 studies (N = 107,370 patients). The use of the LAGB may be related to a rate of around 30% for reoperation (95% confidence interval [CI] = 20.4%–41.4%), 18% for band removal (95% CI = 13.3%–24.5%), 12% for nonresponse (95% CI = 5.2%–23.8%), 8% for port/tube complications (95% CI = 5.1%–13.6%), 7% for slippage/prolapse (95% CI = 5.3%–9.7%), 6% for pouch enlargement (95% CI = 3.4%–9.9%), and 3% for erosion/migration (95% CI = 2.0%–4.3%) in the long- and very long-term follow-up. However, the quality of evidence was considered very low. Conclusion: Despite the very low quality of evidence, LAGB was associated with not negligible rates of unfavorable outcomes in long- and very long-term follow-up.
目的:目的是评估与病态肥胖的腹腔镜可调节胃束带(LAGB)相关的长期和非常长期不良结局率。方法:本系统评价采用系统评价首选报告项目和荟萃分析声明。从开始到2021年10月，在MEDLINE (PubMed)、EMBASE、LILACS、临床试验和Google Scholar数据库中进行了证据搜索。主要入选标准为接受LAGB的肥胖成人，不良结局，至少随访4年。使用非比较性研究的综合meta分析软件对结果进行汇总，并对证据质量进行排序。当I2 >50%时，假设异质性。由于在检索的研究和几个不受控制的变量之间存在预期的差异，我们使用随机效应模型进行比例荟萃分析。结果:从28项研究(N = 107,370例患者)中提取了23,916个不良结局的数据。在长期和极长期随访中，LAGB的使用可能与再手术率约30%(95%置信区间[CI] = 20.4%-41.4%)，带拔出率为18% (95% CI = 13.3%-24.5%)，无反应率为12% (95% CI = 5.2%-23.8%)，口/管并发症率为8% (95% CI = 5.1%-13.6%)，滑脱/脱垂率为7% (95% CI = 5.3%-9.7%)，眼袋增大率为6% (95% CI = 3.4%-9.9%)，糜烂/移位率为3% (95% CI = 2.0%-4.3%)有关。然而，证据的质量被认为非常低。结论:尽管证据质量很低，但在长期和极长期随访中，LAGB与不可忽略的不良结局发生率相关。

Background: Early identification of patients at risk of poor weight loss following bariatric surgery may provide an opportunity for timely addition of intervention to optimize weight loss. This study investigates the relationship between early postsurgery weight loss trajectory and final weight loss outcomes. Methods: Data from patients who underwent primary sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), or one-anastomosis gastric bypass (OAGB) between October 2014 and March 2020 at a single institution were analyzed retrospectively. Total weight loss percentage (%TWL) was calculated at 1, 3, 6, 9, 12, 18, 24, 30, and 36 months postsurgery. Regression analysis demonstrated associations between early weight loss and %TWL between 12 and 36 months. Multivariate analysis identified predictors of maximal weight loss (MWL) and insufficient weight loss (IWL). Results: Six hundred and sixteen patients met the inclusion criteria. Follow-up weights were available at 12 months for n = 571, 18 months for n = 382, 24 months for n = 344, 30 months for n = 198, and 36 months for n = 187. The median (interquartile range) MWL for SG, RYGB, and OAGB was 29.9% (24.3–35.7), 32.5% (27.5–38.2), and 38.0% (32.6–42.4), respectively. On multivariate linear regression, MWL was best predicted by 3–6-month %TWL after both SG (P < 0.001) and OAGB (P < 0.001) and by 6–9-month %TWL following RYGB (P < 0.001). Conclusion: Early weight loss predicts MWL and %TWL up to 36 months following laparoscopic SG, RYGB, and OAGB. Identification of poor weight loss responders early may represent an opportunity to intervene to optimize postsurgical outcomes.
