[A Case of Percutaneous Transhepatic Duodenal Drainage for Duodenal Stump Suture Failure after Gastrectomy].

79-year-old man underwent laparoscopic distal gastrectomy with early gastric cancer 0-Ⅱc lesion on the greater curvature side of the lower body of the gastric body on gastric cancer screening. On the 10th day after the operation, abdominal pain and fever were observed, and CT revealed suture failure and intra-abdominal abscess. Partial gastrectomy and Roux- en-Y reconstruction were performed in emergency surgery, but duodenal stump suture failure was observed on the third day of reoperation. For duodenal stump suture failure, a catheter was placed in the duodenum by applying PTCD technology, and drainage of the bile duct and duodenal contents was performed, and conservative healing was successful. Duodenal stump suture failure after Roux-en-Y reconstruction is intractable and can sometimes result in death with severe infection and intra-abdominal hemorrhage. Here, we report a case in which duodenal stump suture failure was completely cured by percutaneous transhepatic duodenal drainage, with some literary consideration.
