摘要:

&NA;Deep laceration of the perineum after an obstetric injury may result in a cloacal deformity of the anus and vagina, causing complete fecal incontinence. A surgical technique consisting of reconstruction of the perineal body (perineoplasty) with puborectalis interposition and overlapping external sphincteroplasty is described to correct the defect and restore continence. This procedure has been used on 43 patients in a 10‐year period with excellent anatomic and physiologic results.

摘要:

&NA;To evaluate whether there is a relationship between the viscoelastic properties of the rectum and its surface, barium enema and rectal accommodation studies were performed under standard conditions in 46 subjects (25 adults, 21 children) with chronic idiopathic constipation. In adults, a significant correlation was found between rectal surface at barium enema and the minimum radius of rectal distention with a balloon necessary to higher wall tension changes (r=0.68;P<0.01). In both adults (r=0.48;P<0.05) and children (r=0.57;P<0.01), negative correlations were found between the surface of the rectum and its elasticity. It is concluded that rectal accommodation studies produce data comparable to those of radiologic examinations and may therefore be used repetitively, and without fear of radiation, as follow‐up studies on constipated patients.

摘要:

&NA;A number of investigators have examined the influence of vascular invasion by tumor in colon, rectal, and colorectal cancer. Some consider the presence of vascular invasion an unfavorable prognostic feature and propose treatment recommendations based on its presence. Vascular invasion has two distinct components: blood vessel invasion and lymphatic vessel invasion. The use of elastic tissue stains enhance both the detection of blood vessel invasion and its differentiation from lymphatic vessel invasion. Almost all series report an increased incidence of blood vessel invasion with increasing stage and grade. Although the influence of blood vessel invasion and lymphatic vessel invasion on patterns of failure is variable, both are associated with a decrease in survival; however, treatment recommendations based solely on the presence of blood vessel invasion or lymphatic vessel invasion should be made with caution.
