Introduction. Necrosis of the rectum is an uncommon finding due to abundant collateral vasculature. Its management remains challenging, without clear consensus in the literature.Case Report. We describe a case of a 53-year-old woman with multiple medical comorbidities that presented in septic shock and hematochezia. Colonoscopy revealed ischemic colitis. Conservative management was instituted. At two weeks, she presented evidence of peritonitis. Exploratory laparotomy revealed extensive necrosis of the left colon and rectum. Due to dense inflammation, resection was deemed unsafe. Therefore, a transverse ostomy with mucosal fistula was preformed. Multiple drains were left in place. The patient healed uneventfully.Conclusion. This case illustrates that, if extensive dissection of the distal colon and rectum is unsafe due to the patient's critical condition or technical feasibility, then a diverting ostomy of the proximal viable bowel along with a mucus fistula and good drainage of the abdomen represents an acceptable alternative.

1. Wild rabbits were caught during both phases of the excretory cycle and their gut contents were analysed for volatile fatty acids (VFA).2. All rabbits were found to have high concentrations of VFA in the caecum and in the proximal colon. Acetic was the most abundant acid followed by n-butyric, then propionic.3. VFA concentrations in the caecum and in the proximal colon of rabbits caught during the day and during the night were similar. Hard pellets from the distal colon and rectum of rabbits caught during the night had considerably less VFA than did the soft pellets from rabbits caught during the day.4. Owing to the ingestion of soft faeces, the VFA content of stomach material was greater in rabbits caught during the day than in those caught at night.5. The results are discussed in terms of the mechanism of the diurnal excretion pattern and the role of coprophagy in the rabbit.

Rate Of Movement

Using small (50-100 μm) and large (800-1000 μm) polystyrene particles as a marker substance, transit through the gastrointestinal tract of the rabbit was studied during the formation of hard and soft faeces (caecotrophe). Both fractions of the marker were transported at an equal rate during soft faeces formation. During the formation of hard faeces a significantly higher amount of small particles was present in the caecum, whereas in the distal colon and rectum the number of large particles was elevated significantly.

We studied distal colon of Wistar rats including descending transverse colon and rectum. Feature of distal colon in the left flexure are short mesenterium growing in size towards rectum, common mesenterium with small intestine attached to it on the right side and ligament forming left flexure and attached to it on the left side. It was found that one of the variants of normal blood supply is the absence of a. mesenterica caudalis. In this case blood supply comes from arterial arch formed by a. rectalis media and a. colica media. Moreover, in the classic variant of blood supply we revealed a variation in the amount of straight branches that go to this segment of colon wall from left colic and superior rectal arteries (from 3 to 5 from each artery). The structural features of rectum is weak expression of rectal ampulla that causes the depletion of fecal masses immediately after passing into rectum. Crypt compartment of colon of Wistar rats consists by 80,6 % of obligatory flora represented with Bacteroides ssp., Lactobacillus spp., Bifidobacterium spp., Enterococcus faecalis, E. coli (lac+), Grampositive rods. Facultative flora is represented with Proteus mirabilis, Peptococcus spp., Candida spp., Staphylococcus epidermidis, Citrobacter freundii and makes 19,4 %.
