Influence of the rotation of the diverting loop ileostomy in rectal cancer surgery on small-bowel obstruction: A multicenter prospective study conducted by the Clinical Study Group of Osaka University, Colorectal Group.

Aims: Whether rotation of a diverting loop ileostomy during rectal cancer surgery, for reducing the catastrophic effect of an anastomotic leakage, affects the incidence of small-bowel obstruction has not been fully investigated. The purpose of this study is to explore whether technical maneuvers in diverting loop ileostomy creation, including its rotation, are associated with increased incidence of small-bowel obstruction in rectal tumor surgery.

Methods: This multicenter prospective study was conducted by the Clinical Study Group of Osaka University, which comprises 24 major institutions.

A case of intestinal intussusception with unique hemorrhagic polyps due to AL amyloidosis and excessive anticoagulation.

Most adult intussusceptions are secondary to various pathological conditions that serve as a lead point. Because of their serious nature, intussusceptions often require emergency surgery. We report a surgical case of amyloidosis associated with intussusception, probably due to polypoid protrusions and bleeding tendencies.

[A Case of Rectal Neuroendocrine Carcinoma with Iris Metastasis].

A 62-year-old man with anal pain was diagnosed with rectal neuroendocrine carcinoma. There were multiple metastases in the liver, lung, paraaortic lymph node, and bone of the patient. After performing a diverting colostomy, irinotecan and cisplatin were administered.

[A Case of Jejunal Cancer Treated by Laparoscopic Partial Jejunectomy].

The patient was a 30s male visited our hospital with the complaints of abdominal pain and melena. The internal medicine physician could not detect the cause of the melena by upper and lower gastrointestinal endoscopy. Although the patient resolved with a fast as conservative management so he left our hospital once, he relapsed nausea and abdominal pain.

Clinical Impact of Two-Week Placement of a Subcutaneous Suction Drain in Preventing Incisional Surgical Site Infection in Open Gastrointestinal Surgery with Class 4 Dirty Wound: A Retrospective Study.

Two recent randomized controlled trials demonstrated the beneficial effects of subcutaneous drainage in preventing incisional surgical site infection (SSI) in colorectal surgery. This study aimed to evaluate the efficacy of subcutaneous suction drains (SSDs) compared with primary skin closure (PC) in class 4 dirty wound surgery. Eighty-one patients undergoing open gastrointestinal surgery with class 4 dirty wounds were enrolled in this study, 30 of whom underwent SSD insertion, whereas the other 51 were treated with PC.
