Successful treatment for severe pancreatitis with colonic perforation using video-assisted retroperitoneal debridement: A case report

Spontaneous gallbladder perforation and colon fistula in hypertriglyceridemia-related severe acute pancreatitis: A case report

BACKGROUND

Gallbladder perforation and gastrointestinal fistula are rare but serious complications of severe acute pancreatitis (SAP). However, neither spontaneous gallbladder perforation nor cholecysto-colonic fistula has been reported in acalculous acute pancreatitis patients.

CASE SUMMARY

A 31-year-old male presenting with epigastric pain was diagnosed with hypertriglyceridemia-related SAP. He suffered from multiorgan failure and was able to leave the intensive care unit on day 20. Three percutaneous drainage tubes were placed for profound exudation in the peripancreatic region and left paracolic sulcus. He developed spontaneous gallbladder perforation with symptoms of fever and right upper quadrant pain 1 mo after SAP onset and was stabilized by percutaneous drainage. Peripancreatic infection appeared 1 mo later and was treated with antibiotics but without satisfactory results. Then multiple colon fistulas, including a cholecysto-colonic fistula and a descending colon fistula, emerged 3 mo after the onset of SAP. Nephroscopy-assisted peripancreatic debridement and ileostomy were carried out immediately. The fistulas achieved spontaneous closure 7 mo later, and the patient recovered after cholecystectomy and ileostomy reduction. We presume that the causes of gallbladder perforation are poor bile drainage due to external pressure, pancreatic enzyme erosion, and ischemia. The possible causes of colon fistulas are pancreatic enzymes or infected necrosis erosion, ischemia, and iatrogenic injury. According to our experience, localized gallbladder perforation can be stabilized by percutaneous drainage. Pancreatic debridement and proximal colostomy followed by cholecystectomy are feasible and valid treatment options for cholecysto-colonic fistulas.

CONCLUSION

Gallbladder perforation and cholecysto-colonic fistula should be considered in acalculous SAP patients.

Video-assisted retroperitoneal debridement for infected pancreatic necrosis: A single center series

Introduction and importance

Case presentation

Clinical discussion

Conclusion

•

VARD is a first option when surgery is required for infected necrotizing pancreatic necrosis.

•

The VARD procedure requires placement of percutaneous CT guided retroperitoneal flank drains.

•

Complications of the VARD procedure include bleeding, bowel injury, and pancreatic fistula.

Acute pancreatitis followed by retroperitoneal perforation of the descending colon and a duodenal fistula: Report of a case

•

Retroperitoneal perforation of the colon must be considered in patients with acute pancreatitis.

•

The most common site of perforation is the transverse and descending colon.

•

Retroperitoneal drainage may lead to expansion of the perforation site, necessitating a diverting stoma.

Introduction

There are several reports of colon perforation in patients with acute pancreatitis, but the mechanism is not understood. We describe a patient with acute pancreatitis followed by retroperitoneal perforation of the descending colon and a duodenal fistula.

Case presentation

A 51-year-old male presented with acute pancreatitis. He was hemodynamically unstable, had respiratory failure on admission and was treated in the intensive care unit (ICU). He recovered and left the ICU on day 13. Although his general condition improved, a computed tomography (CT) scan showed air and fluid in the left retroperitoneum. Gastrografin enema and CT scan showed extraluminal leakage in the descending colon and retroperitoneal drainage was performed on day 27. After drainage, there was continuous voluminous feculent discharge, and a loop ileostomy was performed on day 34. A repeat CT scan revealed ascites. A percutaneous catheter injected with contrast showed a duodenal fistula. After drainage, the fever resolved and the patient was discharged on hospital day 106.

Discussion

Although there is no clear mechanism of colonic perforation in patients with acute pancreatitis, one hypothesis is that ischemia secondary to inflammation caused by pancreatitis plays a role. The involved area is usually in the watershed areas of the colon. Retroperitoneal drainage of the colon perforation may have necessitated creation of a diverting loop ileostomy.

Conclusion

Retroperitoneal colon perforation must be considered in patients with acute pancreatitis.
