Conclusions and Summary
The decompressive effects of adjunct procedures commonly used in conjunction with colonic surgery were studied. A 9-inch length of terminal colon was excised and colorectal anastomosis performed. Intracolonic pressures were measured at three levels in the colon 5 cm apart. Resting intracolonic pressures in Group B (sphincter stretched) dogs were significantly higher than those in Group A (controls) and lower than those in Group C (cecostomy) and Group D (colostomy). There was no significant difference between resting intracolonic pressures in Group C and Group D. This study indicates that tube cecostomy and transverse colostomy are equally effective in decompressing the colon in apparently healthy dogs, while forced stretching of the sphincter is not effective. Neostigmine did not increase intracolonic pressure, which seems to suggest that the bowel is not responsive to extraneous parasympathomimetic agents in the early postoperative phase.
