[A Resectable Case of Highly Locally Advanced Cecal Cancer in an Elderly Patient after Bypass Surgery and Chemotherapy].

An 83-year-old woman underwent an examination for right lower abdominal pain and was diagnosed with highly advanced cecal cancer. CT showed no metastasis; thus, we attempted resection or bypass surgery. While no liver metastasis or peritoneal dissemination was observed intraoperatively, the circumflex region was highly infiltrated to the peritoneum and retroperitoneum.

Mixed neuroendocrine-non-neuroendocrine neoplasms of the gallbladder: a case report.

Background:  Primary neuroendocrine tumors of the gallbladder (GB-NETs) are rare, accounting for 0.5% of all NETs and 2.1% of all gallbladder cancers.

[Successful Treatment with Nab-Paclitaxel for Stage Ⅳ Gastric Cancer in an Elderly Patient on Hemodialysis].

An 84-year-old man on hemodialysis was referred to our department for an advanced gastric cancer with pyloric stenosis. Pre-operative CT showed thickening of the stomach wall at the primary lesion and regional lymph node metastasis, while no clear peritoneal metastasis was found. However, we found peritoneal disseminations during the operation, so gastrojejunal bypass was performed.

[Efficacy of Laparoscopic Gastrojejunal Bypass for Unresectable Gastric Cancer with Pyloric Stenosis].

In general, gastrojejunal bypass is performed for unresectable gastric cancers with stenosis. It enables patients to take food and be discharged from the hospital earlier. Previously, we used to primarily perform open gastrojejunal bypass; however, recently, we perform laparoscopic gastrojejunal bypass because it is minimally invasive.
