&NA;To investigate the physiology of improvement in continence following the Ripstein operation for procidentia, preoperative and postoperative anorectal manometry was performed on 11 patients. The mean maximum anal resting pressure increased from 39 to 55 mm Hg (P=0.01). This probably reflects improved function of the internal anal sphincter, which might contribute to better continence by increasing the closing capacity of the anal canal

摘要:

&NA;The value of preoperative nutritional assessment in predicting postoperative morbidity and mortality is controversial. To evaluate the predictive value of preoperative nutritional status, the courses of 100 consecutive patients undergoing colorectal operations were studied prospectively. Subnormal findings for triceps‐skin‐fold thickness (TSF) and percentage of ideal body weight were associated with a significantly higher complication rate, but occurred so infrequently in our patients that the routine use of these tests is not recommended. Subnormal values for commonly obtained nutritional variables may not justify delay of operation for nutritional repletion.

摘要:

&NA;The effect of cholecystectomy on colon carcinogenesis induced by methylazoxymethanol (MAM) acetate was examined in four groups of Syrian golden hamsters. For the sexes combined, the incidences of total large intestinal neoplasms and adenomas in Group 1, which received cholecystectomy and a single intravenous injection of MAM acetate (20 mg/kg body weight), were significantly higher than those of hamsters in Group 2, which were given MAM acetate alone. The combined multiplicities of total large intestinal neoplasms from male and female hamsters, and the multiplicities of those in females of Group 1 were also significantly higher than those in animals in Group 2, respectively. No intestinal tumors were observed in hamsters in Group 3 (cholecystectomy alone) or Group 4 (untreated control). These results indicate an enhancing effect of cholecystectomy on MAM acetate‐induced large intestinal carcinogenesis in hamsters

摘要:

&NA;The records of 187 patients with Crohn's disease who underwent resectional surgery were analyzed to evaluate the effect of several clinical and histologic features on the recurrence rate. Recurrence was defined as the need for re‐resection. The data were analyzed by the life‐table method. Age, sex, age at onset of disease and at time of resection, family history, presence of granuloma, and microscopic involvement at the line of resection did not affect the recurrence rate. The distribution of the disease and duration of symptoms before primary resection did influence the rate of re‐resection. Patients with predominantly large bowel disease (N=56) were found to have a higher rate of re‐resection (45 percent) when compared with 32 percent in patients with small bowel involvement (N=94) and with 35 percent in patients with both small and large bowel involvement (N=37) (P=0.04). a detailed review, an analysis of the literature, and a comparison with our results are made.

摘要:

&NA;This is the 14th case report of squamous cell carcinomain situdeveloping in perianal condyloma acuminata. A 72‐year‐old nonhomosexual man suffered this lesion 11 months after his condyloma was first fulgurated. The lesion was excised locally. He received no local or systemic chemotherapy. Random biopsies on several occasions since that time have not shown any evidence of local recurrence. Squamouscell carcinomain situin perianal condyloma must be distinguished from Bowen's disease and extramammary Paget's disease of the perianal skin, both of which have associated skin rashes. Although Bowen's disease and extramammary Paget's disease frequently are associated with either local or distant malignancies, no such association has been found for squamous cell carcinomain situin condyloma unless the patient also has the aquired immunodeficiency syndrome (AIDS). Since this lesion is a premalignant lesion like Bowen's disease and extramammary Paget's disease, squamous cell carcinomain situin condyloma is treated by local excision. If the margins are free of tumor, the resection is curative. No local or systemic recurrence of this condition has been reported following adequate local resection. Patients with condyloma acuminata should undergo treatment to eliminate all of the warts. When the condylomata recur, or when the patient has AIDS, the lesions should be examined histologically for evidence of premalignant or malignant degeneration

摘要:

&NA;A patient with mucinous adenocarcinoma associated with long‐standing chronic fistula in the cecal region is presented. Association of mucinous carcinoma with chronic fistula seems to occur not infrequently in the anal region, but is extremely rare elsewhere in the large intestine. This is the first report of an occurrence in the cecal region.

摘要:

&NA;Three cases of salmonella colitis with massive lower gastrointestinal hemorrhage are presented. The patients had fever, diarrhea, and abundant hematochezia; blood and bone marrow cultures were positive forSalmonella typhi. Because of bleeding, all patients underwent hemicolecomy; previous mesenteric arteriograms showed the colonic heorrhagic sites. The pathologic and radiologic findings are described
