Computed tomography findings of intersigmoid hernia.

Purpose: To evaluate the computed tomography findings of intersigmoid hernias.

Material And Methods: Between April 2010 and March 2018, 7 patients who were surgically diagnosed with intersigmoid hernia in 3 institutions were enrolled in this study. Two radiologists evaluated imaging findings for the herniated small bowel, the distance between the occlusion point and bifurcation of the left common iliac artery, and the anatomic relationship with adjacent organs.

Computed tomography tractography of anterior abdominal stab wounds.

CT tractography is a simple and useful examination. a non-ionic contrast agent was compression-injected into the stab wound and CT tractography was performed.

Association between low preoperative skeletal muscle quality and infectious complications following gastrectomy for gastric cancer.

Purpose: It is known that sarcopenia affects the overall short- and long-term outcomes of patients with gastric cancer (GC); however, the effect of muscle quality on infectious complications after gastrectomy for GC remains unclear. We investigated the associations between the preoperative quantity and quality of skeletal muscle on infectious complications following gastrectomy for GC.

Methods: The subjects of this retrospective study were 353 GC patients who underwent radical gastrectomy between 2009 and 2018.

Toward standardized patient positioning to avoid peripheral nerve injury during laparoscopic colorectal surgery: Application of a protocol and study of the resulting relationship between total rotation time and contact pressure at the shoulder.

Introduction: Generally, laparoscopic colorectal surgery is performed with the patient in the lithotomy and rotated positions. The lithotomy position, however, is associated with intraoperative peripheral nerve injury (IPNI). We studied the relationship between patient positioning during laparoscopic colorectal surgery, contact pressure at the shoulder, and the occurrence of IPNI and tested a positioning protocol aimed at surgical safety in addition to maintenance of a good surgical field.

Methylation of the DFNA5 gene is frequently detected in colorectal cancer.

Background: Recently, the human deafness, autosomal dominant 5 gene, DFNA5, has frequently been detected in cancer tissues. The methylation status of the DFNA5 gene in colorectal cancer was examined and was compared to the clinocopathological findings.

Materials And Methods: Eighty-five tumor samples and corresponding normal tissues were obtained from patients with colorectal cancer who underwent surgery at our hospital.

Methylation of the homeobox gene, HOPX, is frequently detected in poorly differentiated colorectal cancer.

Background: Homeodomein only protein x (HOPX) gene methylation has frequently been detected in cancer tissues. The methylation status of the HOPX gene in colorectal cancer was examined and compared to the clinocopathological findings.

Materials And Methods: Eighty-nine tumor samples and corresponding normal tissues were obtained from colorectal cancer patients who underwent surgery at our hospital.
