The efficiency of abdominal contra perineal drainage of the pelvic cavity after abdominoperineal resection for carcinoma of the rectum was evaluated retrospectively with regard to the frequency of perineal wound sepsis and length of hospital stay. Thirty-two (45 percent) of 71 patients with perineal drainage developed perineal wound sepsis, compared with four (12 percent) of 32 patients with abdominal drainage (P less than 0.01). Patients with perineal drainage stayed longer in the hospital (mean, 33 days) than those with abdominal drainage (mean, 24 days) (P less than 0.004). Furthermore, postoperative recovery was more comfortable in patients with abdominal drainage. Abdominal drainage therefore is recommended after abdominoperineal resection.
回顾性评估了直肠癌腹会阴切除术后盆腔的腹部对会阴引流的效率，涉及会阴伤口感染的发生率和住院时间。71例采用会阴引流的患者中有32例（45%）发生了会阴伤口感染，而32例采用腹部引流的患者中有4例（12%）发生感染（P<0.01）。采用会阴引流的患者住院时间（平均33天）比采用腹部引流的患者（平均24天）更长（P<0.004）。此外，采用腹部引流的患者术后恢复更舒适。因此，建议在腹会阴切除术后采用腹部引流。
