title: Passive vs. closed suction drainage after perineal wound closure following abdominoperineal rectal excision for carcinoma. A multicenter, controlled trial. The French Association for Surgical Research.
abstract: OBJECTIVE
  Because evacuation of effusion or collection could depend on the type of drainage, we compared the effects of closed suction drainage with passive drainage through tubes or undulated drains after abdominoperineal rectal excision for carcinoma on early and late perineal wound healing.
  
  
  METHODS
  Of 234 consecutive patients undergoing abdominoperineal rectal excision for carcinoma between January 1983 and August 1990, unsatisfactory hemostasis or gross intraoperative septic contamination were recorded in 48 patients who were not included in the trial. After rectal excision and closure of the perineum, the remaining 186 patients were randomized to receive passive drainage (PD; n = 96) or closed suction drainage (SD; n = 90). Eighteen patients were withdrawn because of protocol violation, and three were lost to follow-up, leaving 165 (89 PD and 76 SD) patients for analysis. Preoperative factors (sex, age, degree of obesity, weight loss, anemia, or presence of ascites), intraoperative and pathologic findings (Dukes stage), and postoperative courses (recurrence, late mortality) were similar in both groups. All patients were followed up for 12 months or until death.
  
  
  RESULTS
  The rate of perineums healed at one month was significantly lower (P < 0.05) in PD (55/89 = 61 percent) compared with SD (54/72 = 75 percent) patients. At three months, the rate of healed perineums no longer differed between the two groups (70/87 = 81 percent vs. 60/72 = 84 percent). The number of vaginal fistulas, secondary reopenings, and perineums not healed at 12 months was similar in both groups. Median duration to complete healing was similar in both groups (23 vs. 21 days, respectively). On the other hand, three retained drains were seen in PD patients only. The median duration of hospital stay was identical in both groups (22 days). Seven patients died in the early postoperative period, including one in the PD group and six in the SD group. There was no significant difference in the number of late deaths (3 vs. 7) in PD and SD patients, respectively.
  
  
  CONCLUSIONS
  These results suggest that closed suction drainage should be used after abdominoperineal rectal excision with satisfactory hemostasis or absence of gross introperative septic contamination.
