[Acute hemorrhage from Meckel's diverticulum--Laparotomy or laparoscopy?]

Meckel's diverticulum is the most common congenital malformation of the gastrointestinal tract with a potential risk to develop complications such as obstruction, diverticulitis or intussusception. Lower gastrointestinal bleeding due to ulceration of heterotopic gastric tissue of the diverticulum is a known phenomenon in children and young adults. We present two cases of a 15-year-old girl and a 20-year-old man that revealed a massive lower gastrointestinal hemorrhage of unknown origin. In this emergency situation laparotomy was performed in combination with lower endoscopy as rendezvous manouver. In both cases a Meckel's diverticulum with peptic ulceration was the source of hemorrhage, in one case the bleeding was active and visible. After resection of a short small bowel segment and end-to-end anastomosis the postoperative course was uneventful. We prefer in the case of lower gastrointestinal hemorrhage with hemodynamic instability laparotomy with intraoperative endoscopy instead of laparoscopy.
