Pancreas. 2021 Aug 3. doi: 10.1097/MPA.0000000000001842. Online ahead of print.


OBJECTIVE: Gastrointestinal bleeding (GIB) is an uncommon complication after abdominal surgery. Given the unique risks in the total pancreatectomy with islet autotransplant (TPIAT) population, we aimed to describe this population's incidence of postoperative GIB.

METHODS: Prospectively collected data on patients who underwent a TPIAT from 2001 to 2018 at the University of Minnesota were reviewed for postoperative GIB. Each GIB patient was matched to a control patient and compared for medical, medication, and social history and for clinical outcomes.

RESULTS: Sixty-eight patients developed a GIB (12.4%) at median time after surgery of 17 months. Etiologies included the following: anastomotic ulcer (35%), Clostridium difficile (4%), gastric or duodenal ulcers (9%), esophagitis/gastritis (10%), hemorrhoids (3%), inflammatory bowel disease (4%), Mallory-Weiss tears (1%), and unknown (29%). During diagnostic workup, 87% had an endoscopic procedure and 3% underwent imaging. Seven patients required an operation (10%), 1 required an open embolization (1%), and 13 required endoscopic treatments (19%). Patients with a GIB were more likely to die (15% vs 5%, P = 0.055).

CONCLUSIONS: Twelve percent of patients developed a GIB after TPIAT. One third of those had an undefined etiology despite endoscopy. The need for intervention was high (30%).
