Pancreatic and gastric fistulas are rare complications of emergency splenectomy, and it is extremely rare for a pancreatic fistula to be further complicated by a fistulation into the stomach. Here, we present a case of pancreatogastric fistula in a 60-year-old man who experienced polytrauma due to a blunt mechanism. He underwent emergency splenectomy for splenic injury and developed a pancreatic fistula as a complication. A percutaneous endoscopic procedure was performed to drain the fistula, after which he developed a pancreatogastric fistula as a further complication. A double-pigtail stent was inserted via gastroscopy into the fistula tract to allow internal drainage of the pancreatic collection into the stomach cavity. When a pancreatic fistula is complicated by gastric fistulation, endoscopic stenting of the pancreatogastric fistula tract for internal drainage is an effective treatment option.

Percutaneous nephrostomy is relatively safe for temporary urinary diversion. However, colonic perforation due to percutaneous nephrostomy can happen with an incidence of 0.2% as reported in the English literatures. To our knowledge, this is the first case being reported as a complication following treatment for traumatic renal injury. This paper is to share our treatment approach which differs from the usual approach according to existing literatures. We report on a young man who sustained grade IV renal injury due to blunt trauma and was managed conservatively. The treatment of traumatic renal injury via urinary diversion was complicated with an iatrogenic colonic perforation. The management and subsequent treatment of this patient is discussed in this case report.
