[A Case of Rectal Stenosis For Gastric Cancer Recurrence Effectively Treated with a Colonic Stent].

A man in his 70s underwent distal gastrectomy and D1 dissection with Roux-en-Y reconstruction in March 2009 for advanced gastric cancer with peritoneal metastasis. He was diagnosed with signet-ring cell carcinoma, Stage Ⅳ(T4a, N3a, H0, P1, CY1, M1) and R2. Seventeen cycles of S-1 plus CDDP were administered from April 2009 to December 2010 and 19 cycles of S-1 monotherapy were administered from January 2011 to March 2014. He developed peritoneal recurrence with serum tumor marker elevation in May 2014. Stenosis of the common bile duct, hydronephrosis, and rectal stenosis in Ra-Rs was observed in June 2014. A bile duct stent and a double J catheter was inserted. A colonic stent (NitiTM, 22 mm×6 cm) was also inserted. He could eat after the surgery and was discharged from the hospital. We suggest that a colonic stent is an effective treatment for colon stenosis due to peritoneal metastasis from gastric cancer.

[Gastroduodenal stent placement in gastric cancer patients with pyloric stenosis].

We examined 11 gastric cancer patients undergoing gastroduodenal stent placement for the treatment of gastric outlet obstruction at our hospital, and assessed the significance and problems associated with stenting. None of the patients exhibited any complications associated with stenting, and the median post-stenting fasting period was 3 days(range, 1-7 days). Oral intake improved significantly in all the patients; in patients with nasogastric tubes, the tubes were removed after stenting. However, in patients with peritoneal dissemination, oral intake alone was not sufficient, and additional parenteral nutrition was required. In conclusion, gastroduodenal stenting is believed to be useful for palliative care in gastric cancer patients with pyloric stenosis.
