Pneumoperitoneum after Endoscopic Duodenal Stent Insertion in a Patient with Percutaneous Transhepatic Biliary Drainage and Biliary Stent: A Case Report.

Pneumoperitoneum after Endoscopic Duodenal Stent Insertion in a Patient with Percutaneous Transhepatic Biliary Drainage and Biliary Stent: A Case Report. Clin Endosc. 2018 Aug 29;: Authors: Choi J, Lee MJ, Lee H, Kim Y, Han JH, Park SM Abstract Early removal of a percutaneous transhepatic biliary drainage (PTBD) tube commonly causes pneumoperitoneum. However, we encountered a patient who developed pneumoperitoneum even with an indwelling PTBD tube. An 84-year-old man was admitted with type III combined duodenal and biliary obstruction secondary to metastatic bladder cancer. A biliary stent was placed using a percutaneous approach, and a duodenal stent was placed endoscopically. A large amount of subphrenic free air was detected after the procedures. Laboratory tests indicated intestinal perforation; however, peritoneal signs were absent. The patient was treated conservatively using an indwelling Levin tube. Seven days later, the massive amount of subphrenic free air disappeared. Follow-up tubography revealed unrestricted bile flow into the small intestine, and the PTBD tube was removed. Prolonged endoscopic procedures in patients with a PTBD tract communicating with the gastrointestinal tract can precipitate pneumoperitoneum. Clinicians should be careful to avoid misdiagnosing this condition as intestinal perforation. PMID: 30153723 [PubMed - as supplied by publisher]
