Spanish Intragastric Balloon Consensus Statement (SIBC): practical guidelines based on experience of over 20 000 cases.

BACKGROUND: intragastric balloons (IGBs) are a minimally invasive, increasingly popular option for obesity treatment. However, there is only one worldwide guideline standardizing the technical aspects of the procedure (BIBC, SOARD 2018). OBJECTIVES: to construct a practical guideline for IGB usage by reproducing and expanding the BIBC survey among the Spanish Bariatric Endoscopy Group (GETTEMO). METHODS: a 140-question survey was submitted to all GETTEMO members. Twenty-one Spanish experienced endoscopists in IGBs answered back. Eight topics on patient selection, indications/contraindications, technique, multidisciplinary follow-up, results, safety, and financial/legal aspects were discussed. Consensus was defined as consensus ≥ 70 %. RESULTS: overall data included 20 680 IGBs including 12 different models. Mean age was 42.0 years-old, 79.9 % were women, and the mean preoperative body mass index (BMI) was 34.05 kg/m². Indication in BMI > 25 kg/m², 10 absolute contraindications, and nutritional and medication measures at follow-up were settled. A mean %TBWL (total body weight loss) of 17.66 % ± 2.5 % was observed. Early removal rate due to intolerance was 3.62 %. Adverse event rate was 0.70 % and 6.37 % for major and minor complications with consensual management. A single case of mortality occurred. IGBs were placed in private health, prior contract, and with full and single payment at the beginning. Seven lawsuits (0.034 %) were received, all ran through civil proceeding, and with favorable final resolution. CONCLUSIONS: this consensus based on more than 20 000 cases represents practical recommendations to perform IGB procedures. This experience shows that the device leads to satisfactory weight loss with a low rate of adverse events. Most results are reproducible compared to those obtained by the BIBC.

Endoscopic treatment of food intolerance after a banded gastric bypass: inducing band erosion for removal using a plastic stent.

BACKGROUND AND STUDY AIMS: Ring complications after a banded Roux-en-Y gastric bypass (RYGB) are usually managed surgically. The aim of this study was to analyze the safety and effectiveness of endoscopic removal of noneroded rings after banded-RYGB, by inducing intragastric erosion of the ring using a self-expandable plastic stent (SEPS). PATIENTS AND METHODS: A total of 41 patients with banded RYGB who had noneroded rings and food intolerance were prospectively enrolled. Patients were treated with endoscopic SEPS placement and ring removal. Data from time of stenting, resolution of symptoms, need for endoscopic dilation, and complications were recorded. RESULTS: Successful ring removal was possible in all patients. In 21 cases, the SEPS induced complete erosion, and in 17 cases the ring was removed a month later because of incomplete erosion at the time of SEPS removal. Nine patients (22.0 %) needed endoscopic dilation after stent removal in order to treat fibrotic strictures. Food tolerance was observed in 32 patients (78.0 %) after the procedure. No patient needed surgery and there were no deaths. CONCLUSIONS: Endoscopic removal of the ring using SEPS appeared to be safe and effective after a banded RYGB.
