Randomized Controlled Trial Comparative Study
Stapled technique for acute thrombosed hemorrhoids: a randomized, controlled trial with long-term results.
This study was designed to compare stapled vs. conventional hemorrhoidectomy for patients with acute thrombosed hemorrhoids. ⋯ Stapled hemorrhoidectomy is safe and effective for acute thrombosed hemorrhoids. Similar to elective stapled procedure, emergency stapled excision has greater short-term benefits compared with conventional excision: diminished pain, faster recovery, and earlier return to work. Long-term results and satisfaction were excellent.

Diverticular disease increased steadily concomitant with elevated rates of overweight and obesity during the 20th century. Therefore, the objective of this study was to investigate whether overweight and obesity in midlife predict future diverticular disease in men. ⋯ In a large community-based sample of middle-aged men, overweight and obesity were strongly linked to future severe diverticular disease leading to hospitalization.

Comparative Study
Inhibitory effects of gastrointestinal electrical stimulation on rectal tone are both organ-specific and distance-related in dogs.
A phenomenon of cross-talk has been noted that electrical stimulation of one part of the gut affects another part of the gut. This study was designed to investigate whether the effect of electrical stimulation of one part of the gut on another part of the gut was related to the organ or the distance between the stimulation site and the affected organ, and the mechanism of ileum electrical stimulation on rectal tone. ⋯ Electrical stimulation of the stomach, intestine, or colon with long pulses has an inhibitory effect on rectal tone. This inhibitory effect is organ-specific as well as associated with the distance between stimulation site and affected organs. The inhibitory effect of ileum electrical stimulation on rectal tone is mediated by the nitrergic but not sympathetic pathway.
