PURPOSE: Comprehensive multidisciplinary weight management programs encompassing various conservative measures have shown only modest weight loss results in obese children and adolescents; therefore, bariatric surgery for this population has become a matter of discussion. This study aimed to present our experience with and outcomes for laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) in morbidly obese Korean adolescents. MATERIALS AND METHODS: The prospectively established database of all patients undergoing bariatric surgery at Soonchunhyang University Seoul Hospital, Korea between January 2011 and January 2013 was retrospectively reviewed. Adolescents aged 14 to 20 years were included in the present analyses. RESULTS: Twenty-two adolescents underwent bariatric surgery during the study period; 14 underwent LSG and 8, LRYGB. Of these, 17 were female and 5 were male. The mean age was 19 years. Their mean body weight and body mass index (BMI) before surgery were 115 kg and 40.1 kg/m2. The only postoperative complication was intraluminal bleeding in 1 patient, which was managed conservatively. The mean BMI decreased to 29.1 kg/m2 after a mean follow-up of 10 months. The percent excess weight loss (%EWL) at 1, 3, 6, and 12 months postoperatively were 19.6, 39.9, 52.6, and 74.2%, respectively. Only 1 patient showed %EWL less than 30% at 12 months after surgery. All patients with diabetes and sleep apnea were cured of their disease, and other comorbidities also improved or resolved after surgery. CONCLUSION: Bariatric surgery leads to significant short-term weight loss along with resolution of obesity-related comorbidities in obese children and adolescents.

Laparoscopic mini-gastric bypass surgery is a safe and simple surgical intervention for treating morbid obesity and diabetes mellitus and is now being performed more frequently. Radiologists must be critical in their postoperative evaluation of these patients. In this pictorial review, we explain and illustrate the surgical technique, normal postoperative anatomy, and associated complications as seen on imaging examinations, including fluoroscopy and computed tomography.

PURPOSE: Bariatric surgery is relatively new in Korea, and studies comparing different bariatric procedures in Koreans are lacking. This study aimed to compare the clinical outcomes of laparoscopic adjustable gastric banding (LAGB), Roux-en-Y gastric bypass (RYGB), and sleeve gastrectomy (SG) for treating morbidly obese Korean adults. MATERIALS AND METHODS: In this multicenter retrospective cohort study, we reviewed the medical records of 261 obese patients who underwent different bariatric procedures. Clinical outcomes were measured in terms of weight loss and resolution of comorbidities, such as diabetes, hypertension, and dyslipidemia. Safety profiles for the procedures were also evaluated. RESULTS: In terms of weight loss, the three procedures showed similar results at 18 months (weight loss in 52.1% for SG, 61.0% for LAGB, and 69.2% for RYGB). Remission of diabetes, hypertension, and dyslipidemia was more frequent in patients who underwent RYGB (65.9%, 63.6%, and 100% of patients, respectively). Safety profiles were similar among groups. Early complications occurred in 26 patients (9.9%) and late complications in 32 (12.3%). In the LAGB group, five bands (6.9%) were removed. Among all patients, one death (1/261=0.38%) occurred in the RYGB group due to aspiration pneumonia. CONCLUSION: The three bariatric procedures were comparable in regards to weight-loss outcomes; nevertheless, RYGB showed a higher rate of comorbidity resolution. Bariatric surgery is effective and relatively safe; however, due to complications, some bands had to be removed in the LAGB group and a relatively high rate of reoperations was observed in the RYGB group.

Objective: To analyze the incidence of early severe complications following bariatric and metabolic surgery and the experience of their diagnosis, treatment, and risk factors. Methods: In this retrospective observational study, the clinical data of 4255 patients who underwent bariatric and metabolic surgery between May 2010 and May 2022 in the Department of Bariatric and Metabolic Surgery of the First Affiliated Hospital of Nanjing Medical University were retrospectively collected. Among these patients, 1125 were male and 3130 were female. The mean age and body mass index (BMI) of the patients at the time of operation were 31.3±4.5 years and 36.5±6.4 kg/m², respectively. Regarding surgical type, 2397 patients underwent sleeve gastrectomy (SG), 489 underwent Roux-en-Y gastric bypass (RYGB), 1028 underwent sleeve gastrectomy plus jejunojejunal bypass (SG+JJB), and 341 underwent single anastomosis duodenal switch (SADS). The inclusion criteria were patients (1) with a Clavien-Dindo grade of ≥III; (2) who were undergoing SG, RYGB, SG-JJB, or SADS; and (3) who had complete clinical data. The exclusion criteria were patients (1) undergoing revisional surgery and (2) other operations during the bariatric and metabolic surgery. The Clavien-Dindo classification was used to analyze the incidence of early severe postoperative complications and their prognosis. Early severe postoperative complications were defined as Clavien-Dindo ≥ III complications within 30 days after surgery. Meanwhile, multivariate logistic regression model was used to identify risk factors of the complications. Results: Summary of early severe complications following bariatric and metabolic surgery: (1) of the 4255 patients, 22 (12 male and 10 female) exhibited early severe complications (0.52%). The mean age and BMI of these patients were 41.1±9.9 years and 36.9±8.2 kg/m², respectively. Preoperatively, 7 patients had hypertension, 10 had type 2 diabetes mellitus, 1 had respiratory failure, and 1 had heart failure. The severe complications included 9 patients (0.21%) with grade IIIa, 11 (0.26%) with grade IIIb, 1 (0.02%) with grade IVa, and 1 (0.02%) with grade V complications. The incidences of severe postoperative complications in the different surgical procedures were 0.17% for SG (4/2397), 0.61% for RYGB (3/489), 0.58% for SG+JJB (6/1028), and 2.64% for SADS (9/341). The common severe complications were leakage (0.28%, 12 patients), bleeding (0.14%, 6 patients), and obstruction (0.05%, 2 patients). (2) Management of complications: Grade IIIa complications (including eight patients with leakage and one with severe inflammation) were treated with antibiotics, nasogastric and nutritional tube placements, and CT-guided drainage. For grade IIIa complications, five patients with bleeding were treated with reoperation, and all the patients recovered; four patients with leakage were treated with reoperation, wherein three were converted to RYGB and one patient underwent resuturing of the leakage site; two patients with obstruction were treated with adhesiolysis. The patient with grade IVa complication (including respiratory failure complicated with acid aspiration) was treated in the ICU. For the grade V complication, bleeding in a patient with SG+JJB was treated with reoperation, which confirmed the bleeding of short gastric vessels. Unfortunately, the patient died. (3) Risk factor analysis of early severe complications: univariate analysis detected that sex, age, type 2 diabetes mellitus, operation time, and surgical type were associated with postoperative complications (P<0.05). However, multivariate analysis indicated that an age of ≥31.3 years (odds ratio [OR] = 5.423, 95% confidence interval [CI]: 1.004-29.278, P=0.049) and surgical type (SADS: OR = 19.758, 95%CI: 5.803-67.282, P<0.001; RYGB: OR = 9.752, 95%CI: 2.456-38.723, P=0.001; SG+JJB: OR = 5.706, 95%CI: 1.966- 16.559, P=0.001) were independent risk factors of early severe complications following bariatric and metabolic surgery. Conclusion: Bariatric and metabolic surgery is safe. Its common postoperative complications include leakage, bleeding, and obstruction, which require early detection, diagnosis, and treatment to improve treatment outcomes. Age and surgical type are independent risk factors of early severe complications following bariatric and metabolic surgery.

PURPOSE: The aim of this study was to compare short-term outcomes [food tolerance scores (FTS) and quality of life] after three types of restrictive bariatric surgery: laparoscopic adjustable gastric banding (LAGB), laparoscopic greater curvature plication (LGCP), and laparoscopic sleeve gastrectomy (LSG). MATERIALS AND METHODS: From January 2012 to December 2013, all patients that underwent primary surgery were included in one of the LAGB, LGCP, or LSG groups. These three groups were then compared with respect to FTS, gastrointestinal quality of life indices (GIQLI), and the Medical Outcomes Study Short-Form 36 (SF-36) questionnaire. Questionnaires were sent to all patients both pre- and post-operatively. RESULTS: A total of 85 patients (LAGB=45, LGCP=22, and LSG=18) returned the questionnaires in full, and these patients constituted the study cohort. The cohort was predominately female (n=73, 85.9%). Mean percentage excess weight loss (%EWL) values after LAGB, LGCP, and LSG were 65.4+/-27.0%, 65.6+/-25.2%, and 82.7+/-21.7%, respectively (p=0.044). Mean postoperative FTSs and improvements in total GIQLIs after LAGB, LGCP, and LSG were 15.96, 20.95, and 21.33 and -3.40, 6.68, and 18.78, respectively (p<0.05). All procedures produced improvements in the three SF-36 domain scores. Subgroup analysis revealed significant differences between the three procedures in terms of improvements in general health and emotional well-being. CONCLUSION: LGCP is safe and effective at achieving significant weight loss. In terms of food tolerance and GI quality of life, LGCP was found to be comparable to gastric banding and sleeve gastrectomy.

INTRODUCTIONThe Singapore National Survey of 2004 reported the prevalence of obesity to have increased to 6.9%, thus reflecting the profound changes in our society's lifestyle and eating habits. Bariatric surgery has steadily been increasing to counter the ill effects of obesity.

MATERIALS AND METHODSWe audited our prospective series of 31 patients who had laparoscopic adjustable gastric banding (LABG) for morbid obesity performed by our multidisciplinary team at the National University Hospital, Singapore, between August 2004 and December 2006.

RESULTSThe median age at presentation was 40 years old including 6 males and 25 females. Their median BMI was 42.35 kg/m(2). At a median follow-up of 26 months, the median percentage of excess weight loss (%EWL) was 41.95%. The positive impact of gastric banding on comorbidities are evident whereby 15 (94%) of the diabetics had improved glycaemic control with HbA(1)C of 7.7% preoperatively improving to 5.9% postoperatively, and also 8 (58%) now take smaller doses of oral hypoglycaemic agents. Hypertension improved in 4 patients and 2 (11%) were cured. All our patients with dyslipidaemia had their statin doses reduced with marked lowering of serum lipid levels. We had 2 patients (6.45%) with band erosion and another 2 with reflux oesophagitis. Our article also summarises the available surgical procedures while discussing the pros and cons of each.

CONCLUSIONOur results showed that a multidisciplinary programme can achieve significant weight loss for obese patients in Singapore. To achieve long-term weight loss, a commitment of both the medical team and the patient is necessary. Laparoscopy has revolutionised the practice of bariatric surgery worldwide. LAGB is an effective and safe procedure.
