Abstract
An experimental, randomized, prospective study was performed in 64 dogs to evaluate the effect of fecal loading, solely, or in combination with induced peritonitis, on colonic anastomosis. The animals, none of which had bowel preparations, were randomized into four groups. Group I underwent sigmoid resection and standard open end-to-end anastomosis; Group II underwent sigmoid resection and an intracolonic bypass procedure; Group III underwent experimentally induced fecal peritonitis, sigmoid resection, and anastomosis; Group IV underwent induction of fecal peritonitis, sigmoid resection and an intracolonic bypass procedure. Using Fisher's exact test, results indicate a more statistically significant increased leak rate in Group III than in Group III (P=.04), and Group III than in Group IV (P=.03), but no statistically significant anastomotic leak rate between the peritonitis (III and IV) and the nonperitonitis (I and II) groups. A very significant statistical increase in leak rate (P=.002) was observed when comparing the 25 percent leak rate of Groups I and III (anastomosis subjected to fecal contact) with the 0 percent leak rate of Groups II and IV (anastomosis excluded from fecal contact) regardless of the peritonitis. This study suggests that the intraluminal contact of fecal loading at the colonic anastomosis is a more significant factor in anastomotic complications due to dehiscences than peritonitisper se. It follows, therefore, that if feces can be excluded from intraluminal contact with an anastomotic site, an anastomosis can be safely performed even in the presence of treated peritonitis
