A new technique for resection of lower rectal cancer was practiced. It consists of pulling out the rectosigmoid colon and after resecting the involved part the proximal end is turned back to form a cuff. On 19 patients this operation was done after biopsy of the cut ends were reported negative. When the normal anus was preserved the cuffed colon end was anastomosed to it. The postoperative follow-up period lasted from 3 to 10 years, and none developed stomotic recurrence. The 5-year survival rate...

A new technique for resection of lower rectal cancer was practiced. It consists of pulling out the rectosigmoid colon and after resecting the involved part the proximal end is turned back to form a cuff. On 19 patients this operation was done after biopsy of the cut ends were reported negative. When the normal anus was preserved the cuffed colon end was anastomosed to it. The postoperative follow-up period lasted from 3 to 10 years, and none developed stomotic recurrence. The 5-year survival rate was 36.8% in this series. It is suggested that in this technic preservation of the anus depends on the biopsy result. The likelihood of preserving the anus increases with this new technique and it is very unlikely that residual cancerous tissues will be left behind. The advantages of this new technique are: (1) good exposure of the operative field with better view, (2) easy manipulation, (3) diminution of bleeding and shortening of operation time, (4) eliminating the remnant cavity and making daily change of dressings unnecessary, and (5) preserving the normal anus function.

作者介绍一种低位直肠癌切除的新技术,即拖出内翻切除术。本文对31例低位直肠癌切除术在术中先行直肠下切缘病理检查,结果19例(61.2%)病检阴性者,均保留了正常肛门。术后随访3~10年,5年存活率为36.8%,未见局部吻合口处复发。作者认为低位直肠癌切除能否保留肛门,取决于术中病检结果,这样可提高肛门保留率,并可消除残留癌组织的顾虑。此术式的优点是(1) 能使盆腔视野扩大清楚。(2) 便于操作和识别。(3) 减少出血,缩短手术时间。(4) 消除残腔,不必每日换药。(5) 保留了肛门功能。

Objective To explore the feasibility of the technique of megarectum and megasigmoid resections applied to treat the intractable constipation and fecal incontinence following anal reconstruction (anoplasty) was carried out by complete posterior sagittal approach in the pediatric cases. Methods Six patients (age from 2 to 18 years) with congenital imperforate anus and originally treated with perineal anoplasty suffered from intractable constipation and fecal incontinence. Contrast enema showed massive dilated and peristaltic rectosigmoid colon with fecal impaction. Resection of the dilated bowel and anal reconstruction were completely performed by posterior sagittal approach. Results The mean operating time was 205 minutes(ranged, from 125 to 265 minutes) and the average length of resected colon was 23.3 cm (range: 10 to 40cm).There were no intraoperative or postoperative complications. By 2 to 4 months after the operation, all patients obtained voluntary bowel movement. From two months to four months after the anoplasty, all children had controllable defecation. Followed up for 12 to 30 months showed that no patient had constipation or reqired use of the laxatives again. Four of six patients suffered from grade 1 soiling and the other two had grade> 1 soiling. None had urinary retention or incontinence after the procedure. Conclusions The Megarectum and Megasigmoid resection through posterior sagittal approach applied to treat the children with intractable constipation and fecal incontinence following an anoplasty is a very effectiveness method.

目的 探讨 经尾路行巨直肠及乙状结肠切除术治疗肛门成形术后顽固性便秘的可行性。 方法 患儿6例,年龄2~18岁,均为先天性肛门闭锁行会阴肛门成形术后合并顽固性便秘和充盈性大便失禁。钡灌肠示:直肠及乙状结肠高度扩张,蠕动差。6例患儿均经尾路切除直肠及远端乙状结肠,同时行肛门成形术。 结果 平均手术时间205 min(125min~265min),切除扩张肠管长度23.3cm(10cm~40cm)。术后2月~4月后,6例患儿均可控制排便:12月~30月随访结果示:患儿便秘均消失。6例中4例患1度污便,另2例2度污便,无其他术后并发症。结论 尾路切除巨直肠及乙状结肠是治疗无肛术后顽固性便秘的有效方法。

Objective:To determine the formation and distribution of colorectal "high risk adenomas" and the characteristics of high risk factors.Methods:We detected 258 patients by with colonoscopy .The size, location and pattern were recorded when adnomas were found .All adenomas were examined by experienced pathologists,using the WHO classification."High risk adenomas"included those that were larger than 20mm in diameter,those containing villous structures ,and adenomas with moderate and severe dysplasia.Fecal occult blood tests were measured on 51 patients.Results:We found 308 adenomas in 258 patients .In all ,132 adenomas were "high risk adenomas".The percentage of "high risk adenomas" containing one ,two and three high risk factors were 17.4%,75.0%,7.6% respectively.Ninety-six(72%)"high risk adenomas" were located in rectosigmoid colon.The percentage of "high risk adenomas" with positive fecal occult blood was higher than that of no "high risk adenomas".( P< 0.05).Conclusion:Adenomas of particularly high risk of malignatnt transformation are termed "high risk adenomas".They include those that were larger than 20mm in diameter,those comtaining villous structures,and adenomas with moderate and severe dysplasia."High risk adenomas"containing fewer high risk factors may be liable to carcinogenesis .The incidence of recurrent "high risk adenomas"or carcinogenesis in patients whose "high risk adenomas" had been cut under colonoscopy may be higher than that of no "high risk adenomas" previously."High risk adenomas" are mainly located in rectosigmoid colon.So it is important to emphasize the biopsy in rectosigmoid colon.The positive fecal occult blood is higher in patients with "high risk adenomas" ,which indicates that fecal occult blood test may be an easier and more effective method to detect colorectatl neoplasms early.
