Cystocolostomy as an unusual approach to recurrent pancreatic pseudocyst in a Ugandan male with dense hepatogastroduodenal adhesions: A case report

INTRODUCTION AND IMPORTANCE: Pancreatic pseudocyst is one of the most frequent late complications of acute pancreatitis with increasing prevalence in chronic pancreatitis. Other causes include abdominal trauma, biliary tract disease, and other idiopathic causes. 85% resolve spontaneously within 4–6 weeks. Interventions are required for persistently symptomatic, large and complicated pancreatic pseudocysts. Cystocolostomy is a rarely reported pancreatic pseudocyst drainage option. CASE PRESENTATION: 20-year-old male with large recurrent pancreatic pseudocyst following trauma underwent 2 exploratory laparotomies from a peripheral hospital, before referral to Lubaga hospital. Ultrasound-guided cyst drainage was performed. He was readmitted two weeks later with features of cyst recurrence. Re-laparotomy was done and the stomach, duodenum and proximal jejunum were inaccessible due to extensive dense non-obstructive adhesions. Therefore, we performed a transverse cystocolostomy. Patient improved and was discharged on 5th post-operative day. Review was unremarkable at 6 weeks and 3 months post-surgery. CLINICAL DISCUSSION: Current management of pancreatic pseudocyst is percutaneous, endoscopic or laparoscopic drainage. However in cases of large recurrent cysts despite the above interventions, open surgery still has a role. Cystogastrostomy, cystoduodenostomy or cystojejunostomy are the commonly performed drainage options. These 3 options were not possible in this patient due to dense adhesions, hence we performed a transverse cystocolostomy with no post-operative complications. Possible complications from the procedure might include recurrent pancreatitis, pancreatic abscess and stool leak into the pancreatic duct. CONCLUSION: In cases of inaccessibility to the stomach, duodenum and jejunum due to non-obstructing dense adhesions, a pancreatic cystocolostomy can be performed with equally good outcomes.
