The keeping of a pancreaticojejunal anastomotic stent is regarded as a successful and safe means for preventing pancreatic fistula after PD. Recently, the role of pancreaticojejunal anastomotic stents happens to be challenged, as gradually increasing complications have already been seen. Stent-related tiny bowel perforation has just occurred in 2 situations as long-term problems but will not be reported to happen within 7 days after surgery. Here, we report the outcome of a 71-year-old feminine patient complaining of painless jaundice which underwent PD with a pancreaticojejunal anastomotic stent for a duodenal papillary adenocarcinoma (T4N1M0). Four days after surgery, she had a sudden rise in temperature, high white-blood cell matter, significantly elevated C-reactive necessary protein and 400 ml green-brown drainage liquid. Enhanced computed tomography revealed hydrops abdominis. Small bowel perforation caused by stent migration had been considered very first. An emergency exploratory laparotomy was carried out. We located the pancreaticojejunal anastomotic stent, which extended 2 cm through the tiny bowel, and sutured the jejunum opening after cutting away the protruding the main stent. The in-patient recovered efficiently and had been discharged from the seventh time after the second surgery. After a lot more than 12 months of follow-up, the in-patient has been doing well and is free from any observeable symptoms linked to the procedure. We caution that stent-related problems may appear when perioperative patients suffer with unexplained or sudden alterations in essential indications after PD. In addition, the event regarding the pancreaticojejunal anastomotic stent should be reevaluated by future studies.We caution t
