Large Hemobezoar Causing Acute Small Bowel Obstruction After Roux-en-Y Gastric Bypass: Laparoscopic Management.

The present video shows the laparoscopic management of an acute small bowel obstruction (ASBO) after a Roux-en-Y Gastric Bypass (RYGBP), due to the development of an intraluminal hemobezoar involving the jejuno-jejunostomy (j-j). On the first postoperative day (POD), the patient presented persistent abdominal pain, sense of fullness, nausea, and vomiting with traces of blood. The abdominal tube drained a small amount of serous fluid, while blood tests revealed a mild leukocytosis and a slight decrease of the hemoglobin. A CT scan showed the dilation of the excluded stomach, duodenum, and both the alimentary and biliopancreatic limbs. The transition point was located in the common limb, just beyond the j-j, which was dilated by a fluid collection with the radiological aspect of a blood clot. The patient underwent an emergency laparoscopy which confirmed the preoperative radiological findings. An enterotomy was performed at the biliopancreatic stump, and the blood clot was pulled out by suction. The enterotomy was then closed by means of a linear stapler. Postoperative course was uneventful, except for the development of low-grade pneumonia. The patient was discharged on POD 8. ASBO is a worrisome postoperative complication of RYGBP. Although rare, the development of intraluminal hemobezoar should always be considered as a possible cause of ASBO. Laparoscopic management is feasible and effective and does not necessarily entail the complete revision of the j-j.
