Case of colon perforation due to segmental absence of intestinal musculature accompanied by cancer treated with colonic resection and anastomosis.

Background: Segmental absence of intestinal musculature (SAIM) is a partial defect of intestinal muscularis propria without diverticulum. Many reports indicate that the increase in intestinal pressure caused by enemas or endoscopic examinations leads to bowel perforation, but there are few reports involving malignant tumors. Moreover, few reports have had good outcomes after performing one-stage intestinal anastomosis.

Downregulation of cytochrome oxidase 1 induced radioresistance in esophageal squamous cell carcinoma.

Comprehensive gene screening with transposons is a novel procedure for the systematic identification of resistant genes. The present study aimed to use this technique to identify candidate radioresistant genes in esophageal squamous cell carcinoma. A transposon is a base sequence that can translocate to another location in the genome at random.

A Prospective Randomized Trial of Enteral Nutrition After Thoracoscopic Esophagectomy for Esophageal Cancer.

Background: Several studies have reported that postoperative enteral nutrition (EN) reduced complications and decreased weight loss and hospital stay periods; however, the majority of patients analyzed in these studies underwent open thoracic surgery. No studies have been conducted regarding EN in patients after thoracoscopic esophagectomy as a less invasive surgery. The aim of this study was to investigate the efficacy of EN after thoracoscopic esophagectomy.

Postoperative hyperbilirubinemia suggests the occurrence of complications after esophagectomy for esophageal cancer.

Background: Serum bilirubin levels frequently increase after esophagectomy for esophageal cancer. Several studies have reported hyperbilirubinemia in patients with postoperative complications. We aimed to perform a detailed large-scale analysis to clarify this association.
