RESUMO
INTRODUCTION AND IMPORTANCE: Gastroduodenal intussusceptions are rare and usually secondary to gastric lesions acting as the lead point. Gastrointestinal stromal tumors (GISTs) commonly occur in the stomach (40-60%). Other gastric tumors include; adenocarcinomas, leiomyomas, lymphomas among others. When gastric tumors act as lead points in gastroduodenal intussusception, pancreatitis may arise due to compression of the ampulla of Vater or pancreatic head. Gastroduodenal intussusception may mimic other inflammatory upper gastrointestinal conditions leading to delays in early diagnosis and timely intervention. CASE PRESENTATION: A twenty three year old female with gastroduodenal intussusception secondary to a gastric body GIST with associated pancreatitis. This gastroduodenal mass was initially diagnosed as a pancreatic head echo-complex mass by ultrasound. Confirmatory preoperative diagnosis was made after doing contrasted abdominal computed tomography (CT) scan and upper gastrointestinal endoscopy. Open gastric wedge resection was done. Patient had uneventful recovery and was discharged on the fifth postoperative day. CLINICAL DISCUSSION: Gastroduodenal intussusceptions have non-specific clinical features that may lead to delays in making the correct diagnosis. CT scan is a good imaging modality for diagnosing this condition but access is limited in low resource settings. Resection of the organic cause after reducing the intussusception leads to resolution of the symptoms caused by the intussusception, the GIST and the resultant pancreatitis. CONCLUSION: Gastroduodenal intussusception is rare and may present with nonspecific clinical features. Pancreatitis may arise due to the compression effects on the ampulla of Vater or pancreatic head. A high index of suspicion is key in making a timely diagnosis.
RESUMO
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.
