This study was to examine whether 'fit' patients over the age of 50 who require elective surgery for ulcerative colitis are suitable candidates for restorative proctocolectomy, providing that they are continent before operation and that the anal sphincter is preserved in its entirety without stripping of the mucosa or endoanal anastomosis. Between 1986 and 1991, 18 patients 50 to 66 years old (median 55 years: nine men) underwent restorative proctocolectomy with end to end ileoanal anastomosis without mucosal stripping (12 quadruplicated (W), four duplicated (J), two no reservoir). The results were compared 12 (range three to 24) months later with those of 18 matched patients who were less than 50 years of age (median 34 years). In patients over 50, median resting anal pressure was 88 (range 44-131) cm water before and 80 (47-138) cm water after the operation (NS). In patients under 50, median resting anal pressure was 76 (51-128) cm water before and 77 (36-137) cm water after operation (NS). Resting anal pressure in older patients did not differ significantly from that in younger patients either before or after the operation. Both sensory and reflex anal functions were preserved as well after operation in the older patients as in the younger ones. The clinical results in patients over 50 were slightly inferior to the results for the younger patients, but the difference was small and not significant. Hence age alone is not a contraindication to restorative surgery provided that the anal sphincter is preserved in its entirety.
本研究旨在探讨年龄超过50岁、因溃疡性结肠炎需要择期手术的“健康”患者,在术前肛门节制正常且肛门括约肌完整保留、未行黏膜剥脱或肛管内吻合的情况下,是否适合行保留直肠全结肠切除术。1986年至1991年间,18例年龄在50至66岁(中位年龄55岁:9例男性)的患者接受了保留直肠全结肠切除术及端端回肠肛管吻合术,未行黏膜剥脱(12例四袋式(W),4例双袋式(J),2例无贮袋)。12(3至24)个月后,将结果与18例年龄小于50岁(中位年龄34岁)的配对患者的结果进行比较。50岁以上患者术前静息肛管压力中位数为88(44至131)cm水柱,术后为80(47至138)cm水柱(无显著性差异)。50岁以下患者术前静息肛管压力中位数为76(51至128)cm水柱,术后为77(36至137)cm水柱(无显著性差异)。老年患者术前和术后的静息肛管压力与年轻患者相比均无显著差异。老年患者术后感觉和反射性肛门功能与年轻患者一样得到了保留。50岁以上患者的临床结果略逊于年轻患者,但差异较小且无显著性。因此,只要肛门括约肌完整保留,年龄本身并非保留直肠全结肠切除术的禁忌证。
