目的　评估吻合器环形痔切除术治疗脱垂性内痔的安全性和实用性。方法　利用特制的环形吻合器对 5 2例Ⅲ、Ⅳ度环形脱垂性内痔进行手术治疗 ,其中男性 2 4例 ,女性 2 8例 ,平均 6 2岁。结果　手术时间平均8min ,术后住院时间平均 3 5天 ,98%的病人对手术效果满意。吻合口距齿线距离愈近术后痔块回缩愈明显 ,但术中吻合口出血的情况愈多 ,术后肛门部不适的主诉愈多。术后常见的并发症 :尿潴留 34例 (6 5 4% ) ,肛门部疼痛 42例 (80 7% ) ,大便带血 2 0例 (38 5 % ) ,下腹不适及胀痛 12例 (2 3 1% ) ,术后 1周左右有排便困难 8例(15 4% ) ,大便次数增多 4例 (7 7% ) ,肛门部水肿 4例。随访 2周至 10个月 ,1例术后 4个月复发 ,无肛门狭窄、大便失禁发生。结论　与传统手术相比吻合器环形痔切除术治疗脱垂性内痔具有手术简单、术后痛苦少、恢复正常生活早、复发率低、并发症少的特点 ,但远期效果尚待进一步观察 Objective To evaluate the safety and practicability of stapling ring hemorrhoidectomy in the treatment of prolapsed hemorrhoids. Methods Surgical treatment of 52 cases of Ⅲ, Ⅳ degree annular prolapsed hemorrhoids were performed by special ring stapler, including 24 males and 28 females, with an average of 62 years. Results The average operation time was 8 minutes and the postoperative hospital stay was 35 days on average. 98% of the patients were satisfied with the operation results. Anastomotic distance from the tooth line closer to the hemorrhoid block retraction more obvious, but the intraoperative anastomotic bleeding more, more complaints of anal discomfort after surgery more. Postoperative complications included urinary retention in 34 cases (65.4%), anal pain in 42 cases (80.7%), stool bloody in 20 cases (38.5%), abdominal discomfort and pain in 12 cases (2 3 1%). There were 8 cases (15 4%) of defecation difficulty, 4 cases of stool frequency increase (77%) and 4 cases of anus edema about 1 week after operation. Followed up for 2 weeks to 10 months, 1 patient recurred 4 months after operation, no anal stenosis and fecal incontinence occurred. Conclusion Compared with traditional surgery, stapled hemorrhoidectomy for the treatment of prolapsed hemorrhoids has the advantages of simple operation, less postoperative pain, early return to normal life, low recurrence rate and fewer complications, but the long-term effect needs further observation
