Objective and Methodology: A single-centre retrospective study aimed at analysing the outcome of laparoscopic bariatric surgery on super-obese Malaysians with type 2 diabetes mellitus (T2DM) at 12 months following surgery. Demographic details, glycaemic control and weight-loss parameters were analysed.P < 0.01 was considered statistically significant.
Results: Of the 33 patients, 55% were women and 45% were men with a mean age of 40 ± 11 years and body mass index (BMI) of 59.3 ± 9.0 kg/m2. Majority of patients were of Malay ethnicity (82%). Malaysian-Indians and Malaysian-Chinese each accounted for 9% of total case volume. The three types of laparoscopic bariatric surgery recorded in this study were sleeve gastrectomy (82%), Roux-en-Y gastric bypass (9%) and mini-gastric bypass (9%) with operative time of 103.5 ± 31.1, 135.8 ± 32.6 and 116.2 ± 32.3 min, respectively. Percentage total body weight loss was 33.11% ± 9.44% at 12 months following surgery (P < 0.01). BMI change and percentage excess BMI loss showed similar improvement. Glycosylated haemoglobin and fasting blood sugar decreased from pre-operative values of 7.0% ± 1.0% and 7.0 ± 0.9 mmol/L to 5.6% ± 0.4% and 5.0 ± 0.6 mmol/L at 12 months (P < 0.01). Remission of T2DM was noted in 93% of patients. There was no correlation between weight loss and improvement in glycaemic status.
Conclusion: There are significant weight loss and improvement of glycaemic control at 12 months post-laparoscopic bariatric surgery among super-obese Malaysians.
METHODS: A 37-item questionnaire-based survey was conducted to capture the perioperative practices of the global community of bariatric surgeons. Data were analyzed using descriptive statistics.
RESULTS: Response of 863 bariatric surgeons from 67 countries with a cumulative experience of 520,230 SGs were recorded. A total of 689 (80%) and 764 (89%) surgeons listed 13 absolute and relative contraindications, respectively. 65% (n = 559) surgeons perform routine preoperative endoscopy and 97% (n = 835) routinely use intraoperative orogastric tube for sizing the resection. A wide variation is observed in the diameter of the tube used. 73% (n = 627) surgeons start dividing the stomach at a distance of 3-5 cm from the pylorus, and 54% (n = 467) routinely use staple line reinforcement. Majority (65%, n = 565) of surgeons perform routine intraoperative leak test at the end of the procedure, while 25% (n = 218) surgeons perform a routine contrast study in the early postoperative period. Lifelong multivitamin/mineral, iron, vitamin D, calcium, and vitamin B12 supplementation is advocated by 66%, 29%, 40%, 38% and 44% surgeons, respectively.
CONCLUSION: There is a considerable variation in the perioperative practices concerning SG. Data can help in identifying areas for future consensus building and more focussed studies.
METHODS: Fifty-two internationally recognized bariatric experts from 28 countries convened for voting on 90 consensus statements over two rounds to identify those on which consensus could be reached. Inter-voter agreement of ≥ 70% was considered consensus, with voting participation ≥ 80% considered a robust vote.
RESULTS: At least 70% consensus was achieved for 65 of the 90 questions (72.2% of the items), 61 during the first round of voting and an additional four in the second round. Where consensus was reached on a binary agree/disagree or yes/no item, there was agreement with the statement presented in 53 of 56 instances (94.6%). Where consensus was reached on a statement where options favorable versus unfavorable to OAGB-MGB were provided, including statements in which OAGB-MGB was compared to another procedure, the response option favorable to OAGB-MGB was selected in 13 of 23 instances (56.5%).
CONCLUSION: Although there is general agreement that the OAGB-MGB is an effective and usually safe option for the management of patients with obesity or severe obesity, numerous areas of non-consensus remain in its use. Further empirical data are needed.
