RESUMEN
INTRODUCTION: Obesity is a major global health issue with serious consequences, including death. The intragastric balloon (IGB) is a bariatric surgery option but is limited to 6-12 months due to risks such as deflation, migration, and, rarely, intestinal obstruction. These complications are difficult to diagnose and manage. PRESENTATION OF CASE: A 46-year-old woman with an intragastric balloon for ten months experienced gastric distension, excessive salivation, and nausea, leading to hospitalization. Abdominal radiography and a CT scan revealed a small bowel obstruction caused by the balloon, located 40 cm before the ileocecal junction. A laparotomy was performed to explore the surgical site further. An ileotomy was conducted to remove the balloon during the surgery. The patient was discharged in stable condition after five days. DISCUSSION: Complete small bowel obstruction due to intragastric balloon migration in bariatric surgery is very rare. Initial symptoms include mid-gut dilation, nausea, and vomiting. A CT scan is the best method to locate and identify the cause of intragastric balloon migration. Laparoscopy can be challenging in acute obstruction cases due to limited space, increasing the risk of iatrogenic bowel injury. Therefore, laparotomy with a semi-circular ileotomy is a safe treatment option. CONCLUSION: Ileal obstruction due to intragastric balloon migration is a rare but serious complication of bariatric surgery, which requiring immediate surgical intervention. The use of a semi-circular ileotomy during laparotomy has proven to be an effective and safe treatment option for complete obstruction.
