[A Case of Peritoneal Metastasis from an Unresectable Advanced Gastric Cancer with a Good Response to Nivolumab].

A 74-year-old woman presented with abdominal discomfort and was diagnosed with an unresectable advanced gastric cancer(T4aN3aM1, stage Ⅳ)based on a thorough examination. S-1/cisplatin therapy was administered as first-line treatment and paclitaxel/ramucirumab therapy as the second-line treatment. However, because the patient developed a peritoneal dissemination and her lymph node metastasis increased despite these regimens, nivolumab was introduced as a third- line treatment.

[A Case of Gastric Remnant Necrosis Following Laparoscopic Distal Gastrectomy for Gastric Cancer Successfully Treated Using a Conservative Approach].

Introduction: The stomach is an organ considered resistant to ischemia because of the microvascular networks in the stomach wall, and gastric remnant necrosis following gastrectomy is rare. Herein, we report a case of gastric remnant necrosis following gastrectomy successfully treated using a conservative approach.

Case Presentation: An 83-year-old woman underwent laparoscopic distal gastrectomy, D1 plus lymphadenectomy, Billroth Ⅰreconstruction, and suture closure of the esophageal hiatus for early gastric cancer and giant esophageal hiatal hernia.
