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.

Post-laparoscopic sleeve gastrectomy, intrathoracic sleeve migration and its management: A case series and review of literature.

De novo or persistent gastro-oesophageal reflux disease which may or may not be associated with injury of the oesophageal mucosa is now a known complication in post-sleeve gastrectomy patients. Repair of hiatal hernias to avoid such circumstances has been commonly performed, although recurrences may occur resulting in migration of gastric sleeve into the thorax, which is now a well-known complication. We report four cases of post-sleeve gastrectomy patients who presented with reflux symptoms, with their contrast-enhanced computed tomography abdomen showing intrathoracic sleeve migration and had hypotensive lower oesophageal sphincter with normal body motility on their oesophageal manometry. A laparoscopic revision Roux-en-Y gastric bypass surgery with hiatal hernia repair was performed for all four of them. No post-operative complications were seen at 1-year follow-up. Laparoscopic reduction of migrated sleeve with posterior cruroplasty and conversion to Roux-en-Y gastric bypass surgery can be safely performed for patients presenting with reflux symptoms in cases of intra-thoracic sleeve migration with good short-term outcomes.

Evaluation of 30-day morbidity and mortality of laparoscopic cholecystectomy: a multicenter prospective observational Indian Association of Gastrointestinal Endoscopic Surgeons (IAGES) Study.

BACKGROUND: Laparoscopic cholecystectomy (LC) is the standard of care for benign gallstone disease. There are no robust Indian data on the 30-day morbidity and mortality of this procedure. A prospective multicentre observational study was conducted by the Indian Association of Gastro-Intestinal Endo Surgeons (IAGES) to assess the 30-day morbidity and mortality of LC in India. MATERIALS AND METHODS: Participating surgeons were invited to submit data on all consecutive LCs for benign diseases performed between 09/12/2020 and 08/03/2021 in adults. Primary outcome measures were 30-day morbidity and mortality. Univariate and multivariate analyses were performed to identify variables significantly associated with primary outcomes. RESULTS: A total of 293 surgeons from 125 centres submitted data on 6666 patients. Of these, 71.7% (n = 4780) were elective. A total LC was carried out in 95% (n = 6331). Laparoscopic subtotal cholecystectomy was performed in 1.9% (n = 126) and the procedure were converted to open in 1.4% of patients. Bile duct injury was seen in 0.3% (n = 20). Overall, 30-day morbidity and mortality were 11.1% (n = 743) and 0.2% (n = 14), respectively. Nature of practice, ischemic heart disease, emergency surgery, postoperative intensive care, and postoperative hospital stay were independently associated with 30-day mortality. Age, weight, body mass index, duration of symptoms, nature of the practice, history of Coronavirus Disease-2019, previous major abdominal surgery, acute cholecystitis, use of electrosurgical or ultrasonic or bipolar energy for cystic artery control; use of polymer clips for cystic duct control; conversion to open surgery, subtotal cholecystectomy, simultaneous common bile duct exploration, mucocele, gangrenous gall bladder, dense adhesions, intraoperative cholangiogram, and use of drain were independently associated with 30-day morbidity. CONCLUSION: LC has 30-day morbidity of 11.1%, 30-day mortality of 0.2%, conversion to open rate of 1.4%, and bile duct injury rate of 0.3% in India.

The first international Delphi consensus statement on Laparoscopic Gastrointestinal surgery.

BACKGROUND: Laparoscopic surgery has almost replaced open surgery in many areas of Gastro-Intestinal (GI) surgery. There is currently no published expert consensus statement on the principles of laparoscopic GI surgery. This may have affected the training of new surgeons. This exercise aimed to achieve an expert consensus on important principles of laparoscopic GI surgery. METHODS: A committee of 38 international experts in laparoscopic GI surgery proposed and voted on 149 statements in two rounds following a strict modified Delphi protocol. RESULTS: A consensus was achieved on 133 statements after two rounds of voting. All experts agreed on tailoring the first port site to the patient, whereas 84.2% advised avoiding the umbilical area for pneumoperitoneum in patients who had a prior midline laparotomy. Moreover, 86.8% agreed on closing all 15 mm ports irrespective of the patient's body mass index. There was a 100% consensus on using cartridges of appropriate height for stapling, checking the doughnuts after using circular staplers, and keeping the vibrating blade of the ultrasonic energy device in view and away from vascular structures. An 84.2% advised avoiding drain insertion through a ≥10 mm port site as it increases the risk of port-site hernia. There was 94.7% consensus on adding laparoscopic retrieval bags to the operating count and ensuring any surgical specimen left inside for later removal is added to the operating count. CONCLUSION: Thirty-eight experts achieved a consensus on 133 statements concerning various aspects of laparoscopic GI Surgery. Increased awareness of these could facilitate training and improve patient outcomes.

Religious Fasting of Muslim Patients After Metabolic and Bariatric Surgery: a Modified Delphi Consensus.

BACKGROUND: Fasting during Ramadan is one of the five pillars of the Muslim faith. Despite the positive effects of fasting on health, there are no guidelines or clear recommendations regarding fasting after metabolic/bariatric surgery (MBS). The current study reports the result of a modified Delphi consensus among expert metabolic/bariatric surgeons with experience in managing patients who fast after MBS. METHODS: A committee of 61 well-known metabolic and bariatric surgeons from 24 countries was created to participate in the Delphi consensus. The committee voted on 45 statements regarding recommendations and controversies around fasting after MBS. An agreement/disagreement ≥ of 70.0% was regarded as consensus. RESULTS: The experts reached a consensus on 40 out of 45 statements after two rounds of voting. One hundred percent of the experts believed that fasting needs special nutritional support in patients who underwent MBS. The decision regarding fasting must be coordinated among the surgeon, the nutritionist and the patient. At any time after MBS, 96.7% advised stopping fasting in the presence of persistent symptoms of intolerance. Seventy percent of the experts recommended delaying fasting after MBS for 6 to 12 months after combined and malabsorptive procedures according to the patient's situation and surgeon's experience, and 90.1% felt that proton pump inhibitors should be continued in patients who start fasting less than 6 months after MBS. There was consensus that fasting may help in weight loss, improvement/remission of non-alcoholic fatty liver disease, dyslipidemia, hypertension and type 2 diabetes mellitus among 88.5%, 90.2%, 88.5%, 85.2% and 85.2% of experts, respectively. CONCLUSION: Experts voted and reached a consensus on 40 statements covering various aspects of fasting after MBS.

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.

Undiagnosed Hyperglycemia Is a Potential Long-term Risk in Metabolic Surgery Patients: 7 Years Follow-up Study.

INTRODUCTION: Diabetes is considered to be a surgically correctable illness. As glycemic control begins soon after surgery, the cessation of anti-diabetic medications is early. Patients believe that their diabetes has been "cured" and the need for blood sugar monitoring is forgotten, leading to undiagnosed hyperglycemia and risk of diabetes-related complications. AIMS: To study the effect of bariatric surgery on long-term glycemic control and identify the patients with undiagnosed hyperglycemia. METHODS: All patients with type 2 diabetes who underwent bariatric surgery at our center from January 2012 to December 2013 were included in the study. For each patient, demographic, preoperative, and postoperative data were retrospectively reviewed. RESULTS: Out of the total 119 patients with diabetes, 91 patients underwent sleeve gastrectomy and 28 underwent Roux-en-Y gastric bypass. Diabetes status at 7 years of follow-up was possible in 53 (44.5%) patients: 44 (48.4%) in SG and 9 (32.2%) in RYGB groups. Overall, complete remission at 7 years was seen in 17 (32.1%) patients and partial remission in 12 (22.6%) patients. Amongst non-remitters (n = 24, 45.3%), 7 (13.2%) patients were on medications with good glycemic control (A1C < 6.5) while 8 (15.1%) patients had poor control (A1C > 6.5) despite ongoing medications. Additionally, 9 (17%) patients had poor glycemic control (A1C > 6.5) and were not receiving any anti-diabetic medications. Patients in whom follow-up A1C was unavailable and their diabetes status remain unknown were 66 (55.5%) at 7 years. CONCLUSION: Our study clearly demonstrates high risk of undiagnosed hyperglycemia. Regular long-term follow-up in diabetic patients is even more desirable than amongst patients undergoing bariatric surgery for weight loss alone. Graphical abstract.

The role of upper gastrointestinal endoscopy in bariatric procedure selection: A case series and literature review.

BACKGROUND: Bariatric surgery leads to a significant improvement in obesity and associated comorbidities. Safe surgical outcomes are especially desirable in bariatric, as most patients perceive it as an aesthetic surgery, while an intestinal/gastric surgery may be associated with morbidity. A detailed pre-operative evaluation is required to avoid surgical surprises and post-operative complications. Besides other routine investigations, pre-surgery upper gastrointestinal (GI) endoscopy has always been a topic of debate. Some surgeons perform it routinely before the surgery, whereas others perform it selectively. It is mostly accepted that pre-operative diagnosis of gastro-oesophageal reflux disease could change the plan of surgery in favour of Roux-en-Y gastric bypass although similar consensus does not exist in favour of Sleeve gastrectomy if a gastric/duodenal pathology is detected pre-operatively in a planned roux-en-y gastric bypass patient. AIM: Through this case series, we want to highlight the role of routine pre-operative upper GI endoscopy in selecting the bariatric surgery. CASES: We present four cases, from amongst many others, where endoscopy changed the course of bariatric surgery. CONCLUSION: Upper GI endoscopy should be performed before bariatric surgery, even in asymptomatic patients, to avoid post-operative surprise/complication.

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 on General Surgical Practice in India.

The coronavirus disease 2019 (COVID-19) pandemic is a global health crisis, and surgeons are at increased occupational risk of contracting COVID-19. The impact of the disease on prevalent general surgical practice is uncertain and continues to evolve. The study aimed to study the impact of COVID-19 on general surgical practice in India and the future implications of the pandemic. A survey questionnaire was designed and electronically circulated 1 month after India entered a national lockdown during COVID-19 pandemic, amongst members of Indian Association of Gastro-intestinal Endo-surgeons (IAGES), a surgical association with nearly eight thousand members from across the country. Survey questions pertaining to pre-COVID era surgical practices, impact on current practice, and financial implications were asked. Responses were collected and statistically analyzed. One hundred fifty-three surgeons completed the survey, of which only 9.2% were women. Majority (41%) were into practice for more than 20 years; 36.6% were into private practice at multiple hospitals (free-lancers). Amongst the respondents, 41.8% had mainly laparoscopic practice with mean outpatient consultation of 26 patients/day and elective surgeries of 43 cases/month prior to lockdown. Post-lockdown, daily outpatient consults reduced to 4 patients per day, and 77% had not performed a single elective procedure. Hydroxychloroquine (HCQ) chemoprophylaxis was reported by 52% surgeons. Personal protective equipment (PPE) was used by 52% for all cases, while 71.5% stated there are insufficient guidelines for future surgical practice in terms of safety. A drop of more than 75% of their monthly income was experienced by 52% surgeons, while 22% faced 50-75% reduction. One third (33%) of respondents own a hospital and are expecting a monthly financial liability of 2.25 million rupees (nearly 30,000 US dollars). COVID-19 has led to a drastic reduction in outpatient and elective surgical practices. There is a definite need for guidelines regarding safety for future surgical practices and solutions to overcome the financial liabilities in the near future.

Prevalent bariatric dietary practices: Is India on the same page?

BACKGROUND: In the past decade, there has been an increase in the number and types of bariatric procedures in India. It is, thus, important to monitor prevalent bariatric practices. AIM: To identify prevalent pre- and post-operative dietary practices by bariatric professionals across India. MATERIALS AND METHODS: Data regarding various pre- and post-surgery dietary practices were collected using an Internet-based survey. Thirty-three bariatric professionals including dietitians (n = 25) and surgeons (n = 8) across the country participated in the survey. The data were analysed, and prevalent dietary practices were identified. RESULTS: Five (20%) dietitians were not involved in the pre-surgery consultation. Nineteen (70%) professionals put all patients on a low-calorie pre-surgery diet regardless of their body mass index, with a preference (n = 21; 77.7%) for liquid diet. Twenty-three (70%) professionals put patients on post-surgery liquid diet for 1-2 weeks. Thereafter, 28 (84.8%) professionals recommended soft diet for 2-4 weeks. Twenty-seven (81%) professionals used protein shakes (as opposed to dietary sources) as their primary source of protein for the first 3 months post-surgery. Fourteen (36%) professionals stopped protein shake supplements within 6 months post-surgery. Ten (30%) professionals reported whey protein aversions in >25% of the patients. Twenty-three (71%) professionals advocated a meal with <30% of carbohydrates for up to 1 year. Twenty-eight (84%) professionals used portion control method for meals. CONCLUSION: Our study reflects that prevalent dietary practices among Indian bariatricians are in line with national and international guidelines.

Is sleeve gastrectomy overcriticized? A single-center Indian experience with 5-year follow-up results.

BACKGROUND: Bariatric surgery has seen a sharp rise in numbers worldwide in the last decade. Being a popular procedure, sleeve gastrectomy (SG) has been widely studied over the years for its efficacy, potential for weight regain, metabolic impact, and de novo gastroesophageal reflux disease (GERD). OBJECTIVES: To evaluate clinical outcomes of laparoscopic SG after 5 years of follow-up in terms of weight loss, co-morbidity resolution, and GERD. SETTING: The study was performed in a center of excellence in bariatric surgery in India. METHODS: All patients who underwent laparoscopic SG from January 2012 to April 2013 were included in the study. Their demographic, preoperative, and postoperative data were prospectively maintained in Microsoft Excel and analyzed statistically. RESULTS: Two hundred eighteen patients underwent SG in 2012-2013. Patients had a preoperative body mass index of 45.8 ± 9.5 kg/m2 (mean ± standard deviation) and excess weight of 54.1 ± 25.6 kg. Percent excess weight loss was 87.6% ± 28.9% at 1 year, 77.2% ± 29.3% at 3 years, and 69.1% ± 27.8% at 5 years. Percent total weight loss at 1 year was 35.5% ± 7.6%, 31.4% ± 9.1% at 3 years, and 29.2% ± 9.8% at 5 years. At 5 years, 11 of 25 (44%) showed complete diabetic remission and 5 of 25 (20%) showed partial remission. De novo GERD was seen in 24 of 153 (15.7%) patients. CONCLUSION: Our study reflects good outcomes after SG in terms of weight loss and diabetes resolution at 5-year follow-up, though GERD remains a matter of concern.

Portion Control Eating-a Determinant of Bariatric Outcomes.

INTRODUCTION: Bariatric surgery leads to significant weight loss but the results vary. Application of dietary principles like portion-controlled eating leads to greater weight loss and fewer complications. AIMS: To evaluate the improvement in weight loss outcomes by incorporating portion-controlled eating behavior in postbariatric patients. METHODS: All patients who underwent bariatric surgery from January 2012 to December 2013 were included in the study. Portion-controlled eating behavior was incorporated in the post-bariatric nutritional protocol. Their demographic, preoperative, and postoperative data were prospectively maintained on Microsoft Office Excel and analyzed statistically. RESULTS: Three hundred and seventy-two (89.6%) underwent laparoscopic sleeve gastrectomy (LSG), while 43 (10.4%) underwent laparoscopic Roux-en-Y gastric bypass (RYGB). In the LSG group, lowest (nadir) BMI was 28.99 ± 5.6 kg/m2 and % Excess weight loss (EWL) was 87.3 ± 27.2%, achieved between 1 and 2 years. In the RYGB group, lowest (nadir) BMI was 27.5 ± 12.09 kg/m and % EWL was 94.32 ± 33.12%. Surgical failure (less than 50% EWL) were 10 (3.27%) in the LSG group and 1 (3%) in the RYGB group. There were no leaks reported in our study. CONCLUSION: Our study highlights the importance of postoperative nutritional interventions like portion-controlled eating for successful bariatric outcome.

Weight Loss and Comorbidity Resolution 3 Years After Bariatric Surgery-an Indian Perspective.

INTRODUCTION: Bariatric surgery has seen a sharp rise in India in the last decade. India is one of the 10 most obese nations of the world, ranking second in number of type 2 diabetics. AIMS: To evaluate clinical outcomes of bariatric surgery after 3 years of follow-up in terms of weight loss, co-morbidity resolution, complaints of gastroesophageal reflux disease and weight regain. METHODOLOGY: All patients who underwent bariatric surgery from January to December 2013 with a minimum follow-up of 3 years were included in the study. Their demographic, preoperative, and postoperative data were prospectively maintained on Microsoft Office Excel and analyzed statistically. RESULTS: One hundred seventy-eight patients (157 lap. sleeve gastrectomy and 21 patients lap. RYGB) completed 3 years of follow-up. In the LSG group, patients had a pre-operative BMI 44.8 ± 8.33 kg/sq. m (mean ± S.D.) and excess body weight 52.3 ± 23.0 kg. In the RYGB group, pre-operative BMI was 42.7 ± 8.82 kg/sq. m and excess body weight 45 ± 18.7 kg. In the LSG group, % excess weight loss (EWL) at 1 year was 87.6 ± 24.4% and 3 years was 71.8 ± 26.7%. In the RYGB group, % EWL at 1 year was 97.2 ± 27.3% and at 3 years was 85.8 ± 25.3%. Diabetes resolution was seen in 32 (80%) in LSG group and 11 (91.7%) in RYGB group (Figs. 1, 2, 3, and 4). CONCLUSION: Our study reflects that there is no statistically significant difference between outcomes of sleeve gastrectomy and Roux-en-Y gastric bypass surgery in terms of weight loss and diabetes resolution at 3 years.

Mesenteric Panniculitis-First Case Series After Bariatric Surgery.

Mesenteric panniculitis is an uncommon pathology, of poorly understood etiology, characterized by progressive inflammation and fibrosis of the small bowel mesentery. This disease has been reported usually after other abdominal surgeries. We present two cases of young male patients who underwent laparoscopic sleeve gastrectomy and developed abdominal symptoms within 45-60 days of surgery. Both were investigated for known post-bariatric complications. While first patient presented (5 months later) at an irreversible stage and died within 8-9 months of primary surgery, in second patient, the disease process could be reversed through early intervention, diagnosis, treatment, and compliance. Mesenteric panniculitis is a rapidly progressive entity, which can be adequately treated by early identification and long-term immune-suppressive therapy.
