    In order to study the effects of partial colectomy, 30 rats Wistar were divided into three groups: GI and GII had the cecun and the ileo cecal valve resected and proximal colectomy was performed in GI and distal in GII. GIII had distal colectomy without cecum resection. The length of the remain colon was of 5 cm in all groups. Colostomy was performed in GI , GII and GIII. Parameters evaluated: body weight, fecal composition concerning to water, lipids and proteins on preoperative time and on the 10th, 20th, 30th, 40th, 50th and 60th days of postoperative time. All statistical tests were conducted at a 5% two-sided risk level. The evaluation was made by analysis of variance techniques. Conclusions: Concerning to body weight, there is no significant difference on the late postoperative time in any group or when comparing the three groups on this same period. On late postoperative time, GI and GII had a large amount of fecal water, lipids and proteins when compared to the preoperative time and to GIII. On the 60th day there's no significant difference on the quantity of fecal water when comparing the three groups and the same occurs on the 50th day when considering the quantity of fecal proteins.

    Telescopic straight ileo-anal anastomosis in dogs
    (Acta Cirurgica Brasileira, 2011-09-01) Lupinacci, Renato Arioni [UNIFESP]; Lupinacci, Renato Micelli; Zavadinack Netto, Martin [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    PURPOSE: To study outcomes and functional results of a telescopic straight ileo-anal anastomosis.METHODS: Thirty-six mongrel dogs were submitted to total proctocolectomy and telescopic straight ileo-anal anastomosis (ileal mucosa-submucosa pulled-through the rectal cuff). They were divided in 3 groups, sacrificed after one, two or eight weeks after the initial procedure. Gross and microscopic (degree of cooptation and signs of ischemia) aspects of the anastomosis, as well, the aspect of defecation were analyzed.RESULTS: On microscopy all anastomosis analysed showed a continuous epithelial line and were considered good. After two-months no signs of ischemia were identified. Defecation aspect has considerably changed during the study, so no dogs presented solid defecation within the first two weeks, whereas 80% of dogs presented solid stools after two months.CONCLUSION: Telescopic ileo-anal anastomosis is a safe alternative and may provide good functional results after some small period of time.
