We report a case of an internal hernia through a transverse mesocolon defect after laparoscopic distal pancreatectomy. The patient was a 58-year-old man with an intraductal papillary mucinous neoplasm of the pancreatic body who underwent laparoscopic distal pancreatectomy. During surgery, an approximately 5-cm defect in the transverse mesocolon was inadvertently made. The defect was not closed as it was thought to be large enough to preclude incarceration. However, the patient developed a bowel obstruction 2 months postoperatively. Laparotomy revealed that a loop of the proximal jejunum herniated through the defect and was adherent to the stapled pancreatic stump. An additional loop of the jejunum was herniated through the narrowed mesenteric defect. To our knowledge, this is the first case of an internal hernia through a transverse mesocolon defect after laparoscopic distal pancreatectomy. [ABSTRACT FROM AUTHOR]
