“…As for Banded One Anastomosis Gastric Bypass (LBOAGB), only few reports are available in literature and is, either only anecdotical or includes few patients [ 23 , 34 , 35 , 48 ]. To our knowledge, only one other good series of patients treated with silastic ring mini gastric bypass and a long-term follow-up of 11 years has been published to date [ 24 ].…”

Laparoscopic Banded One Anastomosis Gastric Bypass: A Single-Center Series

Introduction. Laparoscopic one anastomosis gastric bypass (LOAGB) is a relatively new procedure for the treatment of morbid obesity and related comorbidities. On average, this procedure results in good postoperative weight loss with a low complication rate. Recent publications suggest that dumping syndrome and weight regain might be reduced by placing a silicone ring over the gastric pouch during the procedure, so called laparoscopic banded one anastomosis gastric bypass (LBOAGB). Methods. 86 patients undergoing LBOAGB between 2018 and 2020 were enrolled in this retrospective study. Hospital records were used to assess weight loss, comorbidity resolution, and any complications either in the short or medium term. Results. 54 Female and 32 male patients were included with a mean age of 43 years (25–64), preoperative body mass index of 42 kg/m2 (35–49), and preoperative weight of 114 kg (86–162). Thirty-four patients presented with type 2 diabetes (39.5%), 42 patients (49%) diagnosed with hypertension, 24 presented with OSAS (28%), and 21 (24%) hypercholesterolaemia patients were included. In total, 36 patients were diagnosed with multiple comorbidities. The operative data showed an average operative time of 48 minutes with 3.4% of patients suffering from early (minor) complications and 2.3% with a late (minor) complication. One patient required reoperation due to intra-abdominal bleeding. The median length of hospital stay was 2.5 days. Median follow-up was 18 months (5–36). In that period, no patient required ring removal or conversion to Roux-en-Y gastric bypass surgery. Food intolerance/vomiting was present in 1 patient (1.1%), bile reflux was present in 1 patient (1.1%), and no stomal ulcers were observed. Mean % excess weight loss at 12 and 24 months was 72% and 80%, respectively. Fifty-two out of 86 patients (60%) had a complete resolution of comorbidities. A CONUT score >2 (mild malnutrition) was found in 40% of patients, while a CONUT score 0-1 was found in 60% of patients. Conclusion. LBOAGB shows promising results in terms of safety and efficacy in the short term. Further prospective studies will be required to evaluate the consistency of the results in the long term.

“…To address weight regain, a recognised modification to both MGB and RYGB is the use of a ‘silastic ring (SR)’ around the gastric pouch to create a ‘banded bypass’ 6–9. The SR is placed at the mid-to-distal-third of the gastric pouch and can measure between 6.5 and 8 cm in circumference 6–10. Described SR related complications include erosion, slippage, stenosis and intolerance due to poor quality of eating, regurgitation and vomiting 11–13…”

Closed loop small bowel obstruction due to herniation through silastic ring after bariatric surgery

Bariatric surgery is an effective treatment for obesity and obesity-related complications. Weight regain after surgery plagues all methods of bariatric procedures including the minigastric bypass. The use of a ‘silastic ring’ around the gastric pouch has been shown to reduce weight regain. We present here a very rare complication of silastic ring use, in which a loop of small bowel had herniated through the ring and produced a closed loop small bowel obstruction. The patient was successfully treated with an emergency laparotomy to resect the silastic ring and release the herniated bowel. This case highlights the hernia risk that silastic rings pose and cautions careful consideration before their use.
