Gastro-colo-bronchial fistula after laparoscopic sleeve gastrectomy; case report.

Obesity and its related comorbidities is a major health problem worldwide. Sleeve gastrectomy is regarded to be one of the most effective bariatric surgeries with a relatively low risks of complications. Gastrobronchial fistula is an extremely rare and a serious complication after bariatric surgeries, it is associated with major morbidity. A 48-year-old obese lady with a BMI of 40 had underwent laparoscopic sleeve gastrectomy 7 years ago, she developed leak at the 10th postoperative day which was treated with drainage. After 4 years she presented with left subphrenic abscess which was treated with drainage, splenectomy and endoscopic stent. After one year she had repeated chest infections and was coughing-up recently ingested food items. CT-scan showed left subphrenic collection with abnormal fistulous tract between the bronchial tree and the subphrenic cavity. Left thoracotomy was performed, a complex fistula was found between the remnant parts of the gastric fundus, transverse colon and lung. Resection of the fistula was performed, the stomach and colon were closed in 2 layers, resection of the affected segment of lung was performed and the diaphragm was sutured. The BMI was 19 at the last admission. Gastro-colo-bronchial fistula is unreported after sleeve gastrectomy and the management is challenging. Surgeons may follow the same principles of management as in cases of gastrobronchial fistula, but we suggest earlier surgical intervention with the administration of broad spectrum antibiotics. Nutritional deficiencies must be corrected, and such patients must be treated with multidisciplinary team, with an extended duration of follow-up.
