Evaluating the Safety of the Intragastric Balloon: Spanish Multicenter Experience in 20,680 Cases and with 12 Different Balloon Models.

INTRODUCTION: Intragastric balloon (IGB) is a minimally invasive and reversible option for obesity treatment. There is a worldwide growing number of different IGB models. The efficacy and safety profile for each model must be demonstrated. We aim to evaluate IGB safety profile according to the experience of the Spanish Bariatric Endoscopy Group (GETTEMO). METHODS: A survey of 37 IGBs safety-related questions was sent to all GETTEMO members, to retrospectively collect a multicenter Spanish registry. Incidence, causes, and resolution of both major and minor complications and adverse events (AEs), including legal consequences, differentiated for each balloon model were evaluated. Secondary outcome was weight loss data to confirm efficacy. RESULTS: Twenty-one Spanish hospitals experienced in IGBs responded. The overall data encompassed 20,680 IGBs, including 12 different models. Mean %TBWL of 17.66 ± 2.5% was observed. Early removal rate due to intolerance was 3.62%. Mean major complications rate was 0.70% (> 1% in Spatz2, HB, and Spatz3 models), mainly complicated gastric ulcer. Minor AEs rate was 6.37%, mainly esophagitis. Nine cases (0.04%) required surgery. A single case of mortality (0.0048%) occurred. Seven lawsuits (0.0034%) were received, all with favorable resolution. CONCLUSIONS: In the Spanish experience accumulating 20,680 IGBs and including 12 different balloon models, a low incidence rate of major complications and minor AEs are observed (0.70% and 6.37%, respectively), mostly resolved with medical/endoscopic management. IGB shows good tolerance and efficacy profile. These safety data are within the accepted quality standards.

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.

Cellulase, Coca-Cola®, pancreatin and ursodeoxycholic acid in the dissolution of gastric bezoars: why not all together?

Two cases of a chemical dissolution of gastric phytobezoars are presented. The novel approach of that management is the pharmacological mixture than completely made disappear the bezoars in patients fated to surgery removal.

[Gastric pneumatosis and gas in the portal venous system secondary to peptic ulcer]. / Neumatosis gástrica y gas en el sistema venoso portal secundario a una úlcera péptica.

A 72-year-old woman presented to the emergency department with recurrent vomiting without abdominal pain. On physical examination, the patient was afebrile and her abdomen was soft and nontender with a giant abdominal-wall hernia. Upper endoscopy showed a deep, 3-cm ulcer at the gastric angulus. Computed tomography (CT) of the abdomen showed gastric dilatation with gas in the wall and a large part of the digestive tract within the hernia sac. CT imaging also revealed gas throughout the portal venous system. The patient declined surgery. Management was conservative and included correction of fluid and electrolyte balance, and nasogastric drainage for gastric decompression with good response.

[Diagnostic value of colonoscopy indication as predictor of colorectal cancer: is it possible to design a fast track diagnosis?]. / Valor de la indicación de la colonoscopia como predictor de diagnóstico de cáncer colorrectal. Se puede diseñar un circuito rápido de diagnóstico?

BACKGROUND: Diagnostic delay in patients with colorectal cancer (CRC) is a quality indicator and its reduction could improve prognosis of the disease. OBJECTIVE: To analyze the diagnostic value of different colonoscopy indications in CRC and to select the signs or symptoms that, if prioritized in a rapid diagnostic circuit, would be most efficient. MATERIAL AND METHODS: A retrospective analysis of 2219 outpatients who underwent colonoscopy from 2000 to 2007 was performed. For each indication we calculated the sensitivity (S), positive predictive value (PPV), positive likelihood ratio (LR+), and number of colonoscopies needed to diagnose a case of CRC (NND). RESULTS: A total of 179 patients were diagnosed with CRC. The indications with greatest PPV were liver metastases (35.3%), suspicious radiological image (20.8%), and non-distal rectal bleeding (22%). Iron deficiency anemia (11%), constitutional syndrome (10%), any rectal bleeding (9.4%) and rectal syndrome (9%) had intermediate PPV. Constipation (6.3%), alternating constipation-diarrhea (3.3%), changes in bowel habits (3%), distal rectal bleeding (2.1%), diarrhea (1.8%) and abdominal pain (1.1%) had low PPV. The NND was 4 in liver metastases, 7 in non-distal bleeding and 8 in suspicious radiological image. Distal bleeding (13), diarrhea (14), abdominal pain (14), changes in bowel habits (15) and alternating constipation-diarrhoea (21) had negative NND. The subgroup of patients aged >or= 50 years showed lower NND in non-distal rectal bleeding (5), suspicious radiological image (5) and any rectal bleeding (16). CONCLUSIONS: Patients with non-distal rectal bleeding should be prioritized over other indications in a strategy of rapid diagnosis of CRC. Age equal to or more than 50 years should also be considered because this factor seems to reduce NND. Distal bleeding, abdominal pain and changes in bowel habits had low PPV and were associated with other diagnoses than CRC. Consequently, prioritization of these factors would be inefficient.

[An atypical case of massive gastrointestinal hemorrhage]. / Caso atípico de hemorragia digestiva masiva.

Gastrointestinal stromal tumors (GIST) are an infrequent cause (<1%) of severe gastrointestinal hemorrhage. Treatment is mainly surgical through complete tumoral resection. We report the case of a 29-year-old woman who presented to the emergency room with severe gastrointestinal bleeding manifested by melena. On physical examination the patient had a painless, palpable mass in the left abdomen. Esophagogastroduodenoscopy, computed tomography, angiography and urgent surgical intervention led to diagnosis of a jejunal GIST.
