摘要:

&NA;A group of 38 patients with Crohn's colitis underwent measurement of rectal capacity prior to colectomy and ileorectal anastomosis. Median values for constant and maximum tolerated volumes were significantly higher in patients who still possessed a satisfactorily functioning ileorectal anastomosis at a mean follow‐up of 6.8 years, and measurement of these sensory parameters of rectal capacity was of prognostic value in predicting the likely outcome of ileorectal anastomosis.

摘要:

&NA;A prospective study was done on 34 patients using magnetic resonance imaging (MRI) and computed tomography (CT) preoperatively to stage patients with known rectal carcinoma. The study was done to determine the accuracy and clinical usefulness of CT and MRI. The Thoeni staging method was used. Twenty‐four of 30 cases were staged correctly by CT. Sixteen of 27 were staged correctly by MRI. CT detected lymph node metastases in six of 15 cases with one false‐positive. MRI detected lymph node metastases in two of 15 patients with one false‐positive. CT was the preferred examination, and was useful in some cases. These cases included patients with small tumors who were considered for local excision and patients with extensive disease who were candidates for preoperative or intraoperative radiation treatment. MRI demonstrated extensive disease, as did CT in our later cases.

摘要:

&NA;To evaluate the efficacy of povidone‐iodine enemas as a means of preoperative bowel preparation in colonic surgery, 52 mongrel dogs were randomized into two groups. Group 1 received oral neomycinerythromycin combinations in the usual clinical doses, while Group 2 received a single 500‐ml 5 percent povidone‐iodine enema preoperatively. Quantitative bacterial counts obtained at the time of colonic resection revealed that povidone‐iodine was equally effective in reducing the anaerobes, but was significantly superior to neomycinerythromycin combinations in reducing the aerobic colony counts. Bursting pressures, measured three weeks later, were equal in both groups. Despite elevated blood‐iodine levels, no systemic toxicity was noted in Group 2 dogs. It is concluded that half‐strength povidoneiodine, given as a single enema preoperatively, is equally effective as standard preoperative antibiotic preparations and may be the ideal preparation in urgent or emergency colonic operations. Due to reported toxicity of povidone‐iodine in burn wounds, we suggest that initial trials be limited to emergency cases where the potential benefits possibly will be greater than the theoretic risk of iodine toxicity.

摘要:

&NA;Twenty‐one patients with high transsphincteric fistulas treated by the seton technique were re‐examined after two to 14 years. None had recurrent fistulas, but 13 (62 percent) had some degree of continence disturbances. All patients with anal deformities had continence disorders.

摘要:

&NA;Retroperitoneal abscesses may develop insidiously, resulting in delayed diagnosis with significant morbidity and mortality. Subcutaneous emphysema of the thigh may be a late manifestation of this process, and often heralds a poor prognosis because of associated myonecrosis and fulminant sepsis. The presentation and clinical course of such a patient is summarized, and the relevant anatomy of the retroperitoneal spaces that predisposes to this condition is described.

摘要:

&NA;A case of rectal varices confirmed by percutaneous transhepatic inferior mesenteric venography is reported. By using the transhepatic approach, the mesenteric venous tributaries can be catheterized selectively with direct injection of the high‐density dye, and the location and extent of varices are clearly demonstrated. Transhepatic inferior mesenteric venography can be used as an alternative method of angiographic investigation for rectal varices.

摘要:

&NA;A unique case of inflammatory malignant fibrous histiocytoma of the large bowel is presented. This lesion occurred in the colon of an elderly man suffering from weakness, anemia, anorexia, and weight loss. A right hemicolectomy was performed, and six months later, on follow‐up, he was found to be well. The literature on visceral involvement by malignant fibrohistiocytic tumors is reviewed.

摘要:

&NA;A case of localized, perforated diverticulitis of the transverse colon in a 45‐year‐old woman is presented. Preoperatively, this rare disease is indistinguishable from other acute surgical conditions, and often is mistaken for carcinoma at laparotomy. This report increases awareness of this unusual condition, and emphasizes the clinical, diagnostic, and therapeutic implications. Case reports described in the literature are reviewed.
