Laparoscopic resection of a descending colon tumor with right-sided fixation of the sigmoid colon: a case report.

Background: Intestinal malrotation is a condition in which the process of counterclockwise rotation and fixation to the peritoneum and retroperitoneum during fetal life is incomplete. In adults, it is generally asymptomatic and is often discovered incidentally. We report a case of laparoscopic partial resection of the descending colon for a tumor of the descending colon with a rare form of intestinal malrotation in which the inferior mesenteric artery ran symmetrically and the sigmoid colon was fixed to the dorsal cecum and right-sided retroperitoneum.

A perforation of a duodenal diverticulum in a 97-year-old patient after total gastrectomy and Roux-en-Y reconstruction: a case report.

Most duodenal diverticula (DD) are asymptomatic and rarely develop perforations. Perforation is the most serious complication of DD and often requires emergency surgery. A 97-year-old woman who had undergone total gastrectomy and Roux-en-Y reconstruction 30 years ago was referred to our department with chief complaints of abdominal pain and fever during her hospitalization after femoral neck fracture surgery in the orthopedic department.

A case of laparoscopic appendectomy for appendiceal bleeding.

Background: Appendiceal bleeding is very rare, accounting for about 0.4% of all lower gastrointestinal bleeding. We present a case of laparoscopic appendectomy in a patient with a diagnosis of appendiceal bleeding.

Pseudocirrhosis after chemotherapy for gastric cancer with diffuse liver metastases: A case report.

We herein present the case of a patient with pseudocirrhosis occurring after a complete response to chemotherapy for metastatic gastric cancer was achieved. A 72-year-old man was diagnosed with gastric adenocarcinoma with multiple liver metastases.
