Complications after bariatric surgery: A multicentric study of 11,568 patients from Indian bariatric surgery outcomes reporting group.

BACKGROUND: Complications after bariatric surgery are not uncommon occurrences that influence the choice of operations both by patients and by surgeons. Complications may be classified as intra-operative, early (<30 days post-operatively) or late (beyond 30 days). The prevalence of complications is influenced by the sample size, surgeon's experience and length and percentage of follow-up. There are no multicentric reports of post-bariatric complications from India. OBJECTIVES: To examine the various complications after different bariatric operations that currently performed in India. MATERIALS AND METHODS: A scientific committee designed a questionnaire to examine the post-bariatric surgery complications during a fixed time period in India. Data requested included demographic data, co-morbidities, type of procedure, complications, investigations and management of complications. This questionnaire was sent to all centres where bariatric surgery is performed in India. Data collected were reviewed, were analysed and are presented. RESULTS: Twenty-four centres responded with a report on 11,568 bariatric procedures. These included 4776 (41.3%) sleeve gastrectomy (SG), 3187 (27.5%) one anastomosis gastric bypass (OAGB), 2993 (25.9%) Roux-en-Y gastric bypass (RYGB) and 612 (5.3%) other procedures. Total reported complications were 363 (3.13%). Post-operative bleeding (0.75%) and nutritional deficiency (0.75%) were the two most common complications. Leaks (P = 0.009) and gastro-oesophageal reflux disease (P = 0.019) were significantly higher in SG, marginal ulcers in OAGB (P = 0.000), intestinal obstruction in RYGB (P = 0.001) and nutritional complications in other procedures (P = 0.000). Overall, the percentage of complications was higher in 'other' procedures (6.05%, P = 0.000). There were 18 (0.16%) reported mortalities. CONCLUSIONS: The post-bariatric composite complication rate from the 24 participating centres in this study from India is at par with the published data. Aggressive post-bariatric follow-up is required to improve nutritional outcomes.

Impact of COVID-19 pandemic on bariatric surgery in India: An obesity and metabolic surgery society of India survey of 1307 patients.

BACKGROUND: Although safe practice guidelines were issued by the Obesity and Metabolic Surgery Society of India (OSSI) in the end of May 2020, surgeons have been in a dilemma about risk of subjecting patients to hospitalisation and bariatric surgery. This survey was conducted with the objective to evaluate the risk of coronavirus disease-19 (COVID-19) infection in peri- and post-operative period after bariatric and metabolic surgery (BMS). METHODS: A survey with OSSI members was conducted from 20 July 2020 to 31 August 2020 in accordance with EQUATOR guidelines. Google Form was circulated to all surgeon members through E-mail and WhatsAppTM. In the second phase, clinical details were captured from surgeons who reported positive cases. RESULTS: One thousand three hundred and seven BMS were reported from 1 January 2020 to 15 July 2020. Seventy-eight per cent were performed prior to 31 March 2020 and 276 were performed after 1 April 2020. Of these, 13 (0.99%) patients were reported positive for COVID-19 in the post-operative period. All suffered from a mild disease and there was no mortality. Eighty-seven positive cases were reported from patients who underwent BMS prior to 31 December 2019. Of these, 82.7% of patients had mild disease, 13.7% of patients had moderate symptoms and four patients succumbed to COVID-19. CONCLUSION: BMS may be considered as a safe treatment option for patients suffering from clinically severe obesity during the COVID-19 pandemic. Due care must be taken to protect patients and healthcare workers and all procedures must be conducted in line with the safe practice guidelines.

Feasibility and safety of robotic-assisted surgical approach in median arcuate ligament syndrome-a systematic review.

Median arcuate ligament syndrome (MALS) is rare syndrome and is diagnosis of exclusion. Though first robotic median arcuate ligament release (MALR) was described in 2007, there are only a few case reports (CR), case series (CS), and retrospective cohort studies (RCS) in the published literature. The purpose of this study was to assess the feasibility and safety of robotic-assisted MALR (r-MALR). PubMed, Embase, and Cochrane databases were searched (last search December 2023) for articles reporting r-MALR. All studies including CR, CS, RCS reporting technical feasibility (operating time and rate of conversions), safety (intra-operative complications, blood loss, post-operative complications), and outcome (length of stay [LoS]) were included (PROSPERO: CRD42024502792). A total of 23 studies (8-CR, 5-CS, 10-RCS) with total 290 patients were available in the literature. Except 1-RCS, all studies reported age and mean age for CR was 40.38 ± 17.7, 36.08 ± 15.12 for CS, 39.72 ± 7.35 years for RS; except 2-RCS, all studies reported gender distribution and there were 57 males and 214 females. Operating time: 3-CR, 4-CS, 9-RCS reported operating time, and mean time was 111 ± 54, 131.69 ± 7.51, 117.34 ± 35.03 min, respectively. Conversion rate: All studies reported data on conversion and only four (1.37%) cases were converted-one to laparoscopic approach, three to open approach (1-inadvertent celiac arteriotomy, 2-reasons not mentioned). Intraoperative complications: only 5-CR, 4-CS, and 9-RCS reported data on intra-operative complications, and there were only 6 complications (1.5%): 1-inadvertent celiac arteriotomy converted to open; 3-unnamed vascular injuries (2 managed robotically, 1 converted to open); 1-bleeding managed robotically; there were no other reported injuries. Estimated blood loss ranged from 5 to 30 ml. Post-operative complications: 5-CR, 4-CS, 8-RCS described post-operative complications in 21 (7%) patients. Twenty cases were grade I, one was grade IIIa, and all managed successfully. LoS stay: 2-CR, 4-CS, 10-RCS reported LoS and overall, it was 2 days. r-MALR is reasonable, technically feasible, safe, and has acceptable outcomes. In addition, robotic approach provided superior vision, improved dexterity, precise, and easy circumferential dissection.PROSPERO registration: The protocol was registered in the PROSPERO database (CRD42024502792).

30-day morbidity and mortality of revisional bariatric surgery - An international multi-centre collaborative (BROAD) study.

INTRODUCTION: Revisional bariatric surgery (RBS) for insufficient weight loss/weight regain or metabolic relapse is increasing worldwide. There is currently no large multinational, prospective data on 30-day morbidity and mortality of RBS. In this study, we aimed to evaluate the 30-day morbidity and mortality of RBS at participating centres. METHODS: An international steering group was formed to oversee the study. The steering group members invited bariatric surgeons worldwide to participate in this study. Ethical approval was obtained at the lead centre. Data were collected prospectively on all consecutive RBS patients operated between 15th May 2021 to 31st December 2021. Revisions for complications were excluded. RESULTS: A total of 65 global centres submitted data on 750 patients. Sleeve gastrectomy (n = 369, 49.2 %) was the most common primary surgery for which revision was performed. Revisional procedures performed included Roux-en-Y gastric bypass (RYGB) in 41.1 % (n = 308) patients, One anastomosis gastric bypass (OAGB) in 19.3 % (n = 145), Sleeve Gastrectomy (SG) in 16.7 % (n = 125) and other procedures in 22.9 % (n = 172) patients. Indications for revision included weight regain in 615(81.8 %) patients, inadequate weight loss in 127(16.9 %), inadequate diabetes control in 47(6.3 %) and diabetes relapse in 27(3.6 %). 30-day complications were seen in 80(10.7 %) patients. Forty-nine (6.5 %) complications were Clavien Dindo grade 3 or higher. Two patients (0.3 %) died within 30 days of RBS. CONCLUSION: RBS for insufficient weight loss/weight regain or metabolic relapse is associated with 10.7 % morbidity and 0.3 % mortality. Sleeve gastrectomy is the most common primary procedure to undergo revisional bariatric surgery, while Roux-en-Y gastric bypass is the most commonly performed revision.

Trends and progress of bariatric and metabolic surgery in India.

Bariatric and metabolic surgery are being performed in India for 2 decades. Aim of this paper is to evaluate the changing clinical trends over the last 5 years and to present the other aspects helmed by Obesity and Metabolic Surgery Society of India (OSSI) to aid the growth of research, education, data management and registry, quality control, insurance-related issues and policy change. OSSI conducts an annual survey to collect data pertaining to numbers of surgical procedures. With the approval of the executive committee, data collected from 2014 to 2018 were retrieved and analysed. 20,242 surgical procedures were performed in 2018 which is an 86.7% increase from 2014. Laparoscopic sleeve gastrectomy continued to remain the most popular procedure, it's percent share saw a steady decline from 68 to 48%. One anastomosis gastric bypass showed an unprecedented growth from 14 to 34%. Numbers of laparoscopic Roux en y gastric bypass remained constant at 15-16%. OSSI has also initiated a COE program along with training fellowships and focus on registry and inclusion in insurance coverage. National trends over the past 5 years in bariatric surgery have shown emergence of newer procedures like OAGB, although LSG continues to be the most popular procedure performed These trends give an insight on how the field is evolving and the implications for any distinctive requirements unique to this region These will lay out important directives for not only ensuring good treatment outcomes but also increasing awareness about the disease on the whole.

Obesity and Metabolic Surgery Society of India (OSSI) Recommendations for Bariatric and Metabolic Surgery Practice During the COVID-19 Pandemic.

Bariatric and metabolic surgery (BMS), the only effective option for patients with obesity with or without comorbidities, has been stopped temporarily due to the ongoing novel corona virus disease (COVID-19) pandemic. However, there has been a recent change in the governmental strategy of dealing with this virus from 'Stay at Home' to 'Stay Alert' in many countries including India. A host of health services including elective surgeries are being resumed. In view of the possibility of resumption of BMS in near future, Obesity and Metabolic Surgery Society of India (OSSI) constituted a committee of experienced surgeons to give recommendations about the requirements as well as precautions to be taken to restart BMS with emphasis on safe delivery and high-quality care.
