Results of Delorme's procedure for rectal prolapse 总被引:7,自引:4,他引:3
Asha Senapati Ph.D. F.R.C.S. R. J. Nicholls M.Chir. F.R.C.S. J. P. S. Thomson M.S. F.R.C.S. Mr. R. K. S. Phillips M.S. F.R.C.S. 《Diseases of the colon and rectum》1994,37(5):456-460
PURPOSE: This study was designed to examine the results of Delorme's procedure. METHODS: Thirty-two patients (24 males and 8 females, mean age, 70 years) underwent Delorme's procedure between 1978 and 1990 following symptoms lasting between two weeks and ten years. Thirteen patients had had 21 previous operations for prolapse. RESULTS: The mean operation time was 65 minutes. No blood transfusions were needed, there was no operative mortality, and only two patients had complications (one chest infection and one anastomotic dehiscence). No patients were lost to follow-up. Over a mean follow-up of 24 months (4 months to 4 years), 9 patients died of unrelated conditions. There were four recurrences (12.5 percent), two in patients who had each had two previous procedures. Incontinence improved in 46 percent. No patient became constipated and 50 percent of those constipated preoperatively improved. CONCLUSION: Although abdominal rectopexy is safe and has a low recurrence rate (<5 percent), it involves the hazards of a laparotomy. In addition, up to 40 percent of patients become constipated after rectopexy which may be debilitating. Delorme's procedure has a low morbidity, results in good bowel function, and has a low recurrence rate. It can be performed on unfit patients with possible advantages over rectopexy and perhaps should be used more readily. 相似文献

Data on the relationship between population average alcohol consumption and the proportion of the population that drinks alcohol is limited. Nevertheless a quite large and statistically significant positive correlation between them is demonstrated with the six data sets presented here. Part of this relationship is probably the result of confounding variables, but evidence is presented that it could also be of a direct cause and effect nature whose directionality could lie both ways. The importance of a direct relationship lies in the possibilities for prevention of alcohol related problems that might derive from a policy of abstention. 相似文献

Rapid Urease Test in the Management of Campylobacter pyloridis-Associated Gastritis 总被引:39,自引:0,他引:39
Barry J. Marshall MB.BS. F.R.A.C.P. J. Robin Warren MB.BS. F.R.C.P.A. Graham J. Francis B.S. Simon R. Lang ton B.Sc F.A.A.C.B. C. Stewart Goodwin M.A. M.D. B.Chir. F.R.C.Path Dip.Bact. F.R.C.P.A. Elizabeth D. Blincow 《The American journal of gastroenterology》1987,82(3):200-210
Campylobacter pyloridis colonization of the stomach may be an etiological factor in gastritis and peptic ulceration. Campylobacter pyloridis produces large amounts of urease, and the presence of this enzyme in gastric mucosa usually indicates infection with the organism. In this paper we describe the use of a rapid urease test (CLOtest) to detect C. pyloridis infection in gastric mucosal biopsies. In 141 consecutive endoscopy cases, antral biopsies were taken for culture and histology, and an extra biopsy was inserted into the CLOtest gel. There were 79 patients infected with C. pyloridis, 78 of whom were detected by CLOtest: 75% were positive at 20 min, 92% at 3 h, and 98% at 24 h. There were no false positive results. Eighteen infected patients were rebiopsied after a course of amoxycillin and bismuth subcitrate. Active chronic gastritis resolved in eight of nine who were cleared of the organism, but histological gastritis was unchanged in nine patients who were still infected. CLOtest is a simple, sensitive, and highly specific test that enables the endoscopist to diagnose C. pyloridis infection in the endoscopy room. A negative test after antibiotic therapy correlates with clearance of the bacteria and healing of active gastritis. 相似文献

The authors present the cases of two patients with carcinoma of the gallbladder complicating chronic ulcerative colitis. Both patients had concomitant primary sclerosing cholangitis. Twelve such cases of gallbladder carcinoma have been reported in the literature. The presence of primary sclerosing cholangitis in patients with ulcerative colitis is associated with malignancy of the extrahepatic biliary tree. It is suggested that, if colectomy is necessary, the liver should be biopsied and a cholecystectomy performed if the gallbladder is deemed abnormal. 相似文献

A pair of monozygotic twins presented within five months of each other with three colonic carcinomas each. The unusual presentation
of multiple tumors in both twins suggests a genetic mutation. Both patients also had multiple lipomas. 相似文献

Are Endoscopic Measurements of Colonic Polyps Reliable? 总被引:3,自引:0,他引:3
M. Brian Fennerty M.D. F.A.C.G. Jonelle Davidson M.S. Scott S. Emerson M.D. Ph.D. Richard E. Sampliner M.D. F.A.C.G. Lee J. Hixson M.D. Harinder S. Garewal M.D. Ph.D. 《The American journal of gastroenterology》1993,88(4):496-500
Many clinical studies of colorectal adenomatous polyps rely on endoscopic estimation of polyp size. To examine the reliability of such measurements, we conducted a study using artificial polyps in an endoscopy teaching model. Eight experienced endoscopists estimated the size of 13 polyps in two separate sessions 2 wk apart. Endoscopic estimates of polyp size tended to be significantly lower than the true polyp size for all polyps and all endoscopists at both sessions. We also found a statistically significant difference in the magnitude of the underestimation between the first and second session ( p < 0.0001). At the first session, polyps tended to be estimated at 64% of their true size, and at the second session, the estimates tended to be at 77% of the actual polyp size. We estimate the magnitude of the variation in polyp measurements due to individual polyps, endoscopist, and examination session, and discuss the impact these sources of variation have in planning of clinical trials. 相似文献

Using an intramyocardial pH needle probe (21 gauge) to monitor myocardial metabolism during ischemia, we determined the effect of potassium cardioplegia at both moderate and deep hypothermia. Five groups of 5 dogs each were placed on cardiopulmonary bypass and the pH probe was inserted approximately 10 mm into the left ventricular free wall. Cardiac ischemia was achieved by cross-clamping the ascending aorta at 37°C (Group 1), 27°C (Group 2), or 17°C (Group 3). In the remaining two groups, aortic cross-clamping was followed by the infusion of 600 to 800 ml of potassium cardioplegic solution adjusted to cardiac temperatures of 27°C (Group 4) or 17°C (Group 5). In each group, myocardial temperature was maintained constant, electrical and mechanical activity observed, and pH recorded until a plateau was reached or for 3 hours.Our results show a progressive and significant decrease in the metabolic rate with reduction in temperature over the 37° to 17°C range. By abolishing contractile activity, potassium cardioplegia markedly reduces the rate of hydrogen ion accumulation at 27 °C, but at 17 °C the additive effect of cardioplegia is much less pronounced. These observations support the principle of reducing contractile activity to a minimum during elective arrest of the heart but indicate that potassium cardioplegia does little to further reduce the rate of anaerobic metabolism, as shown by the measurement of intramyocardial pH, under conditions of deep hypothermia. 相似文献

A retrospective comparison was made of 47 patients who underwent elective surgical resection for diverticular disease and 106 patients who had sigmoid colectomy or left hemicolectomy for carcinoma over an eight and one-half-year period. There was higher morbidity and mortality in those patients with diverticular disease. 相似文献
