This prospective randomized clinical study was conducted to evaluate the need for drainage after rhomboid excision and a Limberg flap (RELIF) for the treatment of pilonidal sinus.
One hundred one patients undergoing the RELIF procedure were randomly treated with drainage or not. Operating time, postoperative pain assessed on a visual analogue scale (VAS), total amount of intramuscular analgesic administered, hospital stay, complications, recurrence rate, and patient satisfaction were assessed.
The mean operating time (P = 0.036), VAS scores on postoperative day 0 (P = 0.039) and day 1 (P = 0.006), intramuscular analgesic requirement (P = 0.009), mean amount of intramuscular analgesic administered (P = 0.025), complication rate (P = 0.027), and mean hospital stay (P = 0.0001) were significantly reduced in the non-drained group. The recurrence rate was similar in the two groups (P = 0.32).
This study indicates that drain placement after the RELIF procedure might negatively affect the postoperative outcomes of patients with pilonidal sinus. On the basis of these finding, we suggest that the use of drains may not be necessary after the RELIF procedure for the treatment of pilonidal sinus.
本前瞻性随机临床试验旨在评估菱形切除术和 Limberg 皮瓣（RELIF）治疗藏毛窦是否需要引流。
101 例行 RELIF 手术的患者随机接受引流或不引流治疗。评估手术时间、术后视觉模拟评分（VAS）评估的疼痛程度、肌内镇痛总量、住院时间、并发症、复发率和患者满意度。
非引流组的平均手术时间（P = 0.036）、术后第 0 天（P = 0.039）和第 1 天（P = 0.006）的 VAS 评分、肌内镇痛需求（P = 0.009）、肌内镇痛用量（P = 0.025）、并发症发生率（P = 0.027）和平均住院时间（P = 0.0001）均显著降低。两组的复发率相似（P = 0.32）。
本研究表明，RELIF 手术后放置引流可能会对藏毛窦患者的术后结果产生负面影响。基于这些发现，我们建议在 RELIF 手术治疗藏毛窦时，引流的使用可能不是必需的。
