Abstract
BACKGROUND: Spleen-preserving distal pancreatectomy with resection of the splenic vessels (VR-SPDP) is an effective procedure. However, hemodynamic changes in splenogastric circulation may lead to the development of gastric varices (GV) with a risk of gastrointestinal (GI) bleeding. This retrospective study aimed to assess the long-term postoperative clinical follow-up of patients and review the late postoperative abdominal computed tomography (CT) or endoscopic examination. METHODS: From 1988 to 2015, 48 consecutive VR-SPDP for benign or low-grade malignant disease were included. Late postoperative follow-up was undertaken with the use of a prospective database and assessment undertaken by CT and/or endoscopy. RESULTS: The median follow-up was 76 months (range: 12-334 months). Two patients were lost to follow-up. Gastrointestinal hemorrhage occurred in one patient. Endoscopy and abdominal CT showed submucosal GV in five patients. Ten patients had perigastric varices (27%), but none developed clinical complications from their varices. All varices occurred within one year after distal pancreatectomy and remained stable during follow-up. DISCUSSION: Asymptomatic varices frequently occurred in patients who underwent VR-SPDP, but bleeding risk seemed low. Abdominal CT could identify GV and distinguish submucosal varices with a higher risk of gastric bleeding.
