Background
Bleeding pseudoaneurysm (PSA) is a rare but potentially lethal complication of chronic pancreatitis (CP). It requires expeditious management by a multidisciplinary team. The study aims to report our experience with PSA in the background of CP.
Methods
All the patients, who underwent intervention for CP-related PSA between August 2007 and December 2020 in the Department of Surgical gastroenterology, Institute of Postgraduate Medical Education and Research, Kolkata, India were retrospectively reviewed.
Results
Of the total 26 patients, 25 (96%) were men with a median age of 38 (11–63) years. The most commonly involved vessel was the splenic artery (n = 18, 69%). The interval between onset of GI bleed and intervention was 7 (0–120) days. Embolization was attempted in 11(42%) patients and was successful in six patients. Surgery was performed in 20 (77%) patients including five patients after failed embolization. The most commonly performed operation was distal pancreatectomy with splenectomy. The median operating time was 216 (115–313) minutes. The median intraoperative blood loss was 325 (100–1000) ml. Seventeen (85%) patients' required intraoperative blood transfusion. Four patients in the embolization group and five patients in the surgical group developed procedure-related complications. The most common postoperative complication was wound infection followed by pancreatic fistula. There was no procedure-related death. Over a median follow-up of 24 (6–122) months, no patient developed recurrent hemorrhage.
Conclusions
Both embolization and surgery play an important role in the management of PSA. The choice of procedure depends upon the local availability and feasibility of a particular technique.
