Randomized Controlled Trial Comparative Study Clinical Trial
Randomized, controlled trial of carbon dioxide insufflation during colonoscopy.
Insufflation of air is a cause of discomfort during and after colonoscopy. Although this can be minimized by good technique, the use of carbon dioxide insufflation may provide further benefits. Carbon dioxide is rapidly absorbed and excreted through the lungs. We hypothesized that carbon dioxide would alleviate post-colonoscopy discomfort. ⋯ Because there was significantly less abdominal pain ten minutes after colonoscopy in the group in whom carbon dioxide was used, carbon dioxide should be considered as an insufflating gas for colonoscopy.

Sacral neuromodulation is a novel treatment for selected urinary and bowel dysfunctions. A new method is described for electrode implantation, the "minimally invasive sacral neuromodulation implant technique." ⋯ The minimally invasive sacral neuromodulation implant technique seems to be a safe procedure-making sacral neuromodulation implant easier, faster, and safer, in as much as complications could be potentially reduced.

This study aimed to evaluate the impact of surgery-associated variables on recurrence rates after sigmoid resection for diverticulitis. ⋯ Colorectal (rather than colosigmoid) anastomosis was the single predictor of lower recurrence rates after elective sigmoid resection for uncomplicated diverticulitis.

Review Case Reports
Mesenteric phlebosclerosis: a new disease entity causing ischemic colitis.
Nonthrombotic stenosis or occlusion of the mesenteric veins is a rare cause of intestinal ischemia. The aim of this study was to describe a new disease entity causing chronic ischemic colitis. ⋯ These peculiar lesions have not previously been fully described. The cause and pathogenesis still remain unknown. We conclude that such lesions represent a new clinicopathologic disease entity and propose the term "idiopathic mesenteric phlebosclerosis."

Previous reports have suggested that mucinous colorectal adenocarcinomas are more advanced at diagnosis and have a poorer prognosis than nonmucinous colorectal adenocarcinomas. The purpose of this study was to clarify whether the mucin-producing histologic type of carcinoma is associated with a worse prognosis than nonmucinous, differentiated colorectal adenocarcinoma for patients who undergo curative surgery. ⋯ In patients with colorectal carcinomas who underwent surgery with curative intent and who had colorectal carcinomas of the mucinous histologic type, there was significant correlation with prognosis as measured by overall survival rate after adjustment had been made for major confounders.
