Intraperitoneal chemotherapy, in which an anticancer drug is administered directly into the abdominal cavity through an intraperitoneal access port(IP port), is one of the treatment options for advanced gastric cancer with peritoneal metastasis. Herein, we report a case of sheath-like obstruction of the entire catheter of the IP port due to tissue reaction within a short period of time after IP port implantation. The case was a 35-year-old woman with advanced type 4 gastric cancer with peritoneal dissemination. The IP port was placed and intravenous and intraperitoneal chemotherapy using S-1 plus paclitaxel was started. However, in the middle of the second course, the entire catheter was covered with a fibrous capsule and a sheath-like obstruction occurred, so the IP port was removed and a new IP port was reinserted. One of the IP port troubles is obstruction, but such short-term and special obstruction is rare, and the cause is considered to be a foreign body reaction of the catheter.
腹腔内化疗是晚期胃癌伴腹膜转移的治疗选择之一，即通过腹腔内接入端口（IP端口）将抗癌药物直接注入腹腔。在此，我们报告1例IP端口植入后短期内因组织反应导致整个导管出现鞘样梗阻的病例。该病例为一名35岁女性，患有晚期4型胃癌伴腹膜播散。放置了IP端口，并开始使用S-1加紫杉醇进行静脉和腹腔内化疗。然而，在第二个疗程进行到一半时，整个导管被纤维囊覆盖，出现了鞘样梗阻，因此移除了IP端口并重新插入了一个新的IP端口。IP端口的问题之一是梗阻，但如此短期且特殊的梗阻很少见，其原因被认为是导管的异物反应。
