We experienced a case of peritoneal metastasis from gastric cancer with a good response to nivolumab. Herein, this case is reported with some literature review.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. After the operation, he hoped chemotherapy despite risk factors such as renal failure and old age. find more We introduced a reduced dose of weekly nab-paclitaxel to him. After 3 courses, CT showed the primary lesion had decreased in size, and after 6 courses, serum CA19-9 level decreased to 61.8 U/mL from 2,343 U/mL at the before treatment. No serious adverse events were observed during the chemotherapy. However, after 8 courses, the tumor markers was gradually re-increased, and CT showed the primary tumor re-increased after 9 courses. Therefore, he received irinotecan alone as the second-line. He is still alive 1 year and 8 months after diagnosis of gastric cancer. It is generally said that the risk of cancer chemotherapy for dialysis patients and the elderly is high. However, we suggest that it could be safely performed by examining the appropriate drug and dose. Weekly nab-paclitaxel regimen could be one of the promising options for these patients.Laparoscopic pancreaticoduodenectomy(LPD)is less invasive and provides better cosmetic outcomes than open pancreaticoduodenectomy( OPD). LPD without vascular excision and lymph node dissection has been covered by insurance since 2016 in Japan. On the other hand, secondary small bowel volvulus is a rare condition caused after abdominal operation. A 77-year-old woman underwent a laparoscopic pancreaticoduodenectomy with pancreatic cancer of pT2N0M0, pStageⅠB. She suffered from epigastric pain after meal. The abdominal CT revealed counterclockwise rotation of the SMV on SMA about 540 degree. Gastrointestinal endoscopy showed no abnormal findings in May 2017. Her abdominal pain was disappeared in July 2017. But the pain was recurred in May 2019. The abdominal CT revealed mesenteric edema and counterclockwise rotation about 810 degree. Her abdominal pain was disappeared again in February 2020. The counterclockwise rotation was decreased about 540 degree. Between May 2012 and February 2020, 50 patients underwent LPD at Kansai Rosai Hospital. 111 patients who received OPD between 2010 and February 2015 were included for comparison. No significant differences were noted between the LPD and OPD groups with respect to patient age(67.9 vs 70.3), gender(M/F 31/19 vs 70/41). The intraoperative blood loss was lower(106 g vs 1,064 g, p less then 0.0001)and the operation time was longer (624 vs 535 min, p less then 0.0001)in the LPD group than the OPD group. Small bowel volvulus over 270 degree was 7/43 vs 5/106(p=0.0338), and over 360 degree was 6/44 vs 1/110(p=0.0014), respectively. Small bowel volvulus after pancreaticoduodenectomy was frequently observed in the laparoscopic group.A 53-year-old male had a history of gastrectomy of the pyloric side for gastric cancer and Billroth Ⅰ reconstruction done 20 years ago. The patient visited the gastrointestinal internal medical department of our hospital with abdominal pain as the chief complaint. Pancreatic cancer was diagnosed with the help of an abdominal CT, and he was then referred to our department. The preoperative disease stage was cT3, N0, M0, Stage ⅡA. As it was over 20 years since the previous surgery and the preoperative CT showed cardiac branches of the left inferior phrenic artery, we inferred that the residual stomach can be preserved. The blood flow was confirmed by the intraoperative ICG fluorescence method, and we then performed pancreatotomy of the pancreatic tail, preserving the stomach and
