    A patient who presented with massive upper gastrointestinal hemorrhage underwent a Billroth II partial gastrectomy. He developed efferent loop obstruction due to a retained abdominal drain. Relaparotomy for removal of drain was performed. Retained drains are known complications but rarely, it is cause of efferent loop obstruction.

    Sleeve gastrectomy has gained popularity over the years and is commonly performed laparoscopically through multiple small incisions. The arrival of single incision laparoscopic surgery has been a game changer, allowing for sleeve gastrectomy to be performed through a cosmetically more appeasing scar with improved patient
    satisfaction. In this article, we describe the history, technical challenges, proposed solutions to some of the hurdles faced during single-incision laparoscopic bariatric surgery and highlight our method of performing single incision laparoscopic sleeve gastrectomy purely through a single access device.

    To compare 5-year gastroesophageal reflux outcomes following Laparoscopic Vertical Sleeve Gastrectomy (LVSG) and Laparoscopic Roux-en-Y gastric bypass (LRYGB) based on high quality randomized controlled trials (RCTs). We conducted a sub-analysis of our systematic review and meta-analysis of RCTs of primary LVSG and LRYGB procedures in adults for 5-year post-operative complications (PROSPERO CRD42018112054). Electronic databases were searched from January 2015 to July 2021 for publications meeting inclusion criteria. The Hartung-Knapp-Sidik-Jonkman random effects model was utilized to estimate weighted mean differences where meta-analysis was possible. Bias and certainty of evidence was assessed using the Cochrane Risk of Bias Tool 2 and GRADE. Four RCTs were included (LVSG n = 266, LRYGB n = 259). An increase in adverse GERD outcomes were observed at 5 years postoperatively in LVSG compared to LRYGB in all outcomes considered: Overall worsened GERD, including the development de novo GERD, occurred more commonly following LVSG compared to LRYGB (OR 5.34, 95% CI 1.67 to 17.05; p = 0.02; I2 = 0%; (Moderate level of certainty); Reoperations to treat severe GERD (OR 7.22, 95% CI 0.82 to 63.63; p = 0.06; I2 = 0%; High level of certainty) and non-surgical management for worsened GERD (OR 3.42, 95% CI 1.16 to 10.05; p = 0.04; I2 = 0%; Low level of certainty) was more common in LVSG patients. LVSG is associated with the development and worsening of GERD symptoms compared to LRYGB at 5 years postoperatively leading to either introduction/increased pharmacological requirement or further surgical treatment. Appropriate patient/surgical selection is critical to minimize these postoperative risks.

    BACKGROUND: Laparoscopic vertical sleeve gastrectomy (LVSG) is now the most commonly performed bariatric procedure; however, it remains to be elucidated if it delivers equivalent long-term comorbid disease resolution outcomes similar to the longer established laparoscopic Roux-en-Y gastric bypass (LRYGB). We undertook a systematic review and meta-analysis of randomized controlled trials (RCTs) to investigate the comparative 5-year outcomes of both procedures.

    METHODS: Electronic databases (Pubmed, EMBASE, CINAHL) were searched for RCTs conducted in adults (>18y) that compared the 5-year- outcomes of LVSG to LRYGB and described comorbidity outcomes were included. Where data allowed, effect sizes were calculated using the Hartung-Knapp-Sidik-Jonkman estimation method for random effects model. Presence of bias was assessed with Cochrane Risk of Bias 2.0 and funnel plots, and certainty of evidence evaluated by GRADE. The study prospectively registered with PROSPERO (CRD42018112054).

    RESULTS: Three RCTs (LVSG=254, LRYGB=255) met inclusion criteria and reported on chronic disease outcomes. Improvement and/or resolution of hypertension favoured LRYGB (odds ratio 0.49, 95% CI 0.29, 0.84; P =0.03). Trends favoring LRYGB were seen for type 2 diabetes and dysplidemia, and LVSG for sleep apnea and back/joint conditions ( P >0.05). The certainty of evidence associated with each assessed outcome ranged from low to very low, in the setting of 'some' to 'high' bias assessed as being present.

    CONCLUSION: Both LRYGB and LVSG are effective in providing long-term improvements in commonly experienced obesity-related comorbidities; however, the limited certainty of the evidence does not allow for strong clinical conclusions to be made at this time regarding benefit of one procedure over the other.

    A 50-year-old male had an acute jejunogastric intussusception complicating a Bilroth 11 gastrectomy done 20 years previously for peptic ulcer. Preoperatively, the diagnosis was suspected from the plain abdominal radiograph which was subsequently confirmed by barium meal. The patient had an uneventful recovery following resection of the intussuscepted segment and an end-to-end anastomosis. Although rare, the condition is serious and should be recognised promptly and treated surgically. The diagnosis should always be considered in a patient who has had a previous gastrojejunostomy presented with a sudden onset of epigastric pain, bloody vomitus and epigastric mass.

    Sleeve gastrectomy, gastric bypass, gastric banding, and duodenal switch are the most common bariatric procedures performed worldwide. Ninety-five percent of bariatric operations are performed with minimally invasive laparoscopic technique. Perioperative morbidities and mortalities average around 5% and 0.2%, respectively. Long-term weight loss averages around 15% to 25% or about 80 to 100 lbs (40-50 kg). Comorbidities, including type 2 diabetes, hypertension, dyslipidemia, sleep apnea, arthritis, gastroesophageal reflux disease, and nonalcoholic fatty liver disease, improve or resolve after bariatric surgery.

    PURPOSE: Laparoscopic intraperitoneal instillation of local anaesthetic in bariatric surgery proven to reduce postoperative pain. Limited data are available regarding the use of instillation ropivacaine and its impact on the recovery of respiratory effort. This study aims to evaluate the efficacy of laparoscopic intraperitoneal instillation of ropivacaine in reducing acute postoperative pain and enhancing the recovery of respiratory effort in laparoscopic sleeve gastrectomy.

    MATERIALS AND METHODS: This double-blinded RCT enrolled 110 patients who underwent laparoscopic sleeve gastrectomy at Hospital Canselor Tuanku Muhriz UKM from November 2020 to May 2021. Any patients with previous abdominal surgery, chronic kidney disease, or liver disease were excluded. The patients were randomised into two groups: (i) the IPLA group which received ropivacaine intraperitoneal instillation at the dissected left crus and (ii) the placebo group (sterile water instillation). Perioperative analgesia was standardised. The first 24-h postoperative pain was assessed using a VAS. The respiratory effort was assessed using incentive spirometry simultaneously.

    RESULTS: Total of 110 patients were recruited. The VAS score was lower with an enhanced recovery of respiratory effort in the local anaesthetic group compared to the placebo group (P < 0.05) within the first 24 h postoperatively. In addition, the placebo group required additional postoperative analgesia (P < 0.05). No side effects were reported with the use of intraperitoneal instillation of ropivacaine.

    CONCLUSION: The use of intraperitoneal instillation of ropivacaine in laparoscopic sleeve gastrectomy is recommended as it is safe, effectively reduces acute postoperative pain, and enhances the recovery of respiratory effort postoperatively.

    Religious fasting in Ramadan the 9th month of the lunar year is one of five pillars in Islam and is practiced for a full month every year. There may be risks with fasting in patients with a history of metabolic/bariatric surgery (MBS). There is little published evidence on the possible complications during fasting and needs stronger recommendations and guidance to minimize them. An international survey was sent to surgeons to study the types of complications occurring during religious fasting in patients with history of MBS to evaluate the risk factors to manage and prepare more evidence-based recommendations. In total, 21 centers from 11 countries participated in this survey and reported a total of 132 patients with complications occurring during religious fasting after MBS. The mean age of patients with complications was 36.65 ± 3.48 years and mean BMI was 43.12 ± 6.86 kg/m2. Mean timing of complication occurring during fasting after MBS was 14.18 months. The most common complications were upper GI (gastrointestinal) symptoms including [gastroesophageal reflux disease (GERD), abdominal pain, and dyspepsia], marginal ulcers and dumping syndrome in 24% (32/132), 8.3% (11/132) and 23% (31/132) patients respectively. Surgical management was necessary in 4.5% of patients presenting with complications (6/132) patients due to perforated marginal or peptic ulcer in Single Anastomosis Duodenoileostomy with Sleeve gastrectomy (SADI-S), one anastomosis gastric bypass (OAGB) and sleeve gastrectomy (SG), obstruction at Jejunojenostomy after Roux-en-Y gastric bypass (RYGB) (1/6) and acute cholecystitis (1/6). Patients after MBS should be advised about the risks while fasting including abdominal pain, dehydration, and peptic ulcer disease exacerbation, and a thorough review of their medications is warranted to minimize complications.

    Obesity and type 2 diabetes mellitus (T2DM) is an alarming problem globally and a growing epidemic. Metabolic surgery has been shown to be successful in treating both obesity and T2DM, usually after other treatments have failed. This study aims to compare Roux-Y gastric bypass and sleeve gastrectomy in determining early diabetic outcomes in obese Malaysian patients with T2DM following surgery. A total of 172 obese patients with T2DM who were assigned to either laparoscopic Roux-en-Y gastric bypass (LRYGB) or laparoscopic sleeve gastrectomy (LSG) were analysed up to a year post-procedure. The patients' T2DM severity were stratified using the Individualized Metabolic Surgery (IMS) score into mild, moderate and severe. Remission rates of diabetes were compared between surgical techniques and within diabetic severity categories. T2DM remission for patients who underwent either surgical technique for mild, moderate or severe disease was 92.9%, 56.2% and 14.7% respectively. Both surgical techniques improved T2DM control for patients in the study. Comparing baseline with results 1 year postoperatively, median HbA1c reduced from 7.40% (IQR 2.60) to 5.80% (IQR 0.80) (p

    Kidney dysfunction, a deleterious effect of obesity, is now recognized as a relevant health risk. Chemokine (C-C Motif) Ligand 2 (CCL2) is one of the critical chemokines that play a vital role in the development of obesity-related metabolic disease. We aim to measure the changes in urinary CCL2 in our patients before and after their bariatric procedure and examine the correlation between CCL2 and renal function. A prospective cohort study was conducted at our teaching university hospital. Ethics approval was obtained from our institutional review board. Patients with a BMI of ≥37.5 kg/m2 with no history of renal disease were included. They underwent single anastomosis gastric bypass (SAGB), Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG), all performed via laparoscopic approach. Venous blood and urine samples were obtained preoperatively and six months after surgery. A total of 58 patients were recruited, with SG being performed in 74.1% of patients. At six-months follow-up, median (IQR) body weight reduced from 101.35 kgs (20.25) to 76.95 kg (24.62) p

    Gastro-peritoneal fistula is a rare but serious complication of laparoscopic sleeve gastrectomy with significant morbidity and mortality. We present the case of a 42-year-old man who underwent laparoscopic sleeve gastrectomy for morbid obesity and presented later with a history of chronic epigastric pain and severe reflux. Upper gastrointestinal series showed the presence of a communicating fistula between the stomach and the left hemi-diaphragm and peri-splenic area.

    BACKGROUND: Laparoscopic vertical sleeve gastrectomy (LVSG) has overtaken the laparoscopic Roux-en-Y gastric bypass (LRYGB) as the most frequently performed bariatric surgical procedure. To date little has been reported on the long-term outcomes of the LVSG procedure comparative to the traditionally favoured LRYGB. We undertook a systematic review and meta-analysis to review the 5-year outcomes of comparing LVSG and LRYGB. We undertook a systematic review and meta-analysis to compare 5-year weight loss outcomes of randomized controlled trials comparing LVSG to LRYGB.

    MATERIALS AND METHODS: Searches of electronic databases (PubMed, Embase, CINAHL, Cochrane) were undertaken for randomized controlled trials describing weight loss outcomes in adults at 5 years postoperatively. Where sufficient data was available to undertake meta-analysis, the Hartung-Knapp-Sidik-Jonkman estimation method for random effects model was utilized. The review was registered with PROSPERO and reported following in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses.

    RESULTS: Five studies met the inclusion criteria totaling 1028 patients (LVSG=520, LRYGB=508). Moderate but comparable levels of bias were observed within studies. Statistically significant body mass index loss ranged from -11.37 kg/m (range: -6.3 to -15.7 kg/m) in the LVSG group and -12.6 kg/m (range: -9.5 to -15.4 kg/m) for LRYGB at 5 years (P<0.001). Systematic review suggested that LRYGB produced a greater weight loss expressed as percent excess weight and percent excess body mass index loss than LVSG: this was not corroborated in the meta-analysis.

    CONCLUSIONS: Five year weight loss outcomes suggest both LRYGB and LVSG are effective in achieving significant weight loss at 5 years postoperatively, however, differences in reporting parameters limit the ability to reliably compare the outcomes using statistical methods. Furthermore, results may be impacted by large dropout rates and per protocol analysis of the 2 largest included studies. Further long-term studies are required to contradict or validate the results of this meta-analysis.

    Anastomotic leak after bariatric surgery is a rare complication with a recent prevalence ranging from 0.8% to 1.5%. The complication nevertheless can result in morbidity and even mortality. The purpose of this paper is to present a patient who suffered from an anastomotic leak presenting 2 days after laparoscopic sleeve gastrectomy in our intensive care unit. Review of the current literature regarding this complication from critical care perspective is also attempted.

    OBJECTIVE: Intraluminal gastric gastrointestinal stromal tumors (GISTs) located at the posterior wall and near the gastroesophageal junction represent a surgical challenge. We present our experience of laparoscopic transgastric resection for gastric GISTs of such location.

    METHODS: Data of seven patients undergoing laparoscopic transgastric resection were identified and retrospectively reviewed with regard to procedural steps and patient outcomes.

    RESULTS: Seven patients (4 men; mean age 64.1 ± 14.6 years) with gastric GISTs underwent laparoscopic transgastric resection from January 2010 to May 2015. Three of the seven GISTs were located near the gastroesophageal junction and the rest were found in the posterior wall of the stomach. All seven patients underwent successful laparoscopic resection without any conversions. There were no mortalities and no significant postoperative complications. Intraoperative endoscopy was performed for all patients. The mean operative time was 164.0 ± 59.1 minutes. Regular diet was resumed within 3 days on average and mean postoperative stay was 3.6 ± 1.3 days. All patients achieved complete R0 resection with a mean tumor size of 5.5 ± 1.1 cm. At a mean follow-up of 48.0 ± 13.4 months, all patients were recurrence free.

    CONCLUSIONS: GISTs of the posterior wall and in close proximity to the gastroesophageal junction can be safely resected laparoscopically using such an approach. Standard technique is required to achieve good oncological outcomes.
