Abstract:
Objective To explore the etiological factors and therapeutic strategies of acute lower gastrointestinal bleeding (LGIB) for improving the diagnosis and treatment of the disease.
Methods Clinical data of 59 cases of acute LGIB from January 2012 to December 2017 at Zhongshan Hospital, Fudan University were retrospectively analyzed.
Results Etiologies were determined by abdominal computed tomography (CT), angiography, or laparotomy. The major causes of LGIB were vascular malformation of the small intestine (19/59) and the GIST of the small intestine (17/59); other causes included colorectal cancer, colorectal polyp, diverticular disease, malignant tumor of the small intestine (22/59). A total of 49 cases were received surgical procedures.
Conclusions Evidence from the series of cases suggests that preoperative definitive diagnosis by endoscopy, abdominal CT, or angiography is the key to improve the curative effect of acute LGIB.
