- Abstract
Background Intraperitoneal (IP) chemotherapy is garnering attention as an effective treatment for gastric cancer with peritoneal metastasis. We report the case of a patient who developed colonic stenosis caused by infection of an IP access port system during IP chemotherapy. It was difficult to differentiate whether the extrinsic colonic stenosis arose from a catheter infection or peritoneal metastasis of the gastric cancer. Case presentation A 66-year-old Japanese man underwent total gastrectomy for gastric cancer. Because the intraoperative findings revealed peritoneal metastasis, a port system was implanted for subsequent IP chemotherapy. Two months after initiation of chemotherapy, he complained of vomiting and abdominal pain. A computed tomography scan revealed marked thickening of the sigmoid colon wall adjacent to the catheter of the IP access port system. A barium enema demonstrated extrinsic irregular stenosis of the sigmoid colon. Although it was difficult to distinguish whether infection or peritoneal metastasis had caused the colonic stenosis, we removed the port system to obtain a therapeutic diagnosis. Coagulase-negative staphylococci were detected by catheter culture. The wall thickening and stenosis of the sigmoid colon completely resolved after removal of the port system. Conclusions We report the case of a rare complication in association with an IP access port system. Infection of the port system should be considered as a differential diagnosis when colonic stenosis adjacent to the catheter is observed during IP chemotherapy.
