Abstract：
BACKGROUND: Drains are traditionally inserted during surgery for reduction of fluid accumulation in the post-operative period. The appearance of drained fluids and their quantity can be early predictors of complications. Over the years, several studies have been conducted in attempt to determine the optimal number of drains that result in low rates of fluid accumulation with minimal impairment of quality of life.
OBJECTIVE: Determine the optimal number of suction drains in abdominoplasty procedures.
METHODS: Retrospective cohort study, analyzing all abdominoplasty patients operated by a single surgeon. Patients were stratified into 3 groups based on number of drains inserted at the end of the procedure. Rate of complications was compared between the groups and a multivariate logistic regression model was computed for the development of complications.
RESULTS: Seven-hundred and forty three patients were included in the analysis of this study. No drains were inserted in 355 patients (45%), whereas a single drain was inserted in 153 (20.6%) 2 drains in 255 patients (34.4%). Patients for whom a single drain was inserted intra-operatively, experienced at a statistically significant lower rate, surgical site infections (OR = 0.235), hypertrophic scars (OR = 0.326), wound dehiscence (OR = 0.272), as compared to patients with no drains. On the contrary, insertion of single drain was associated with a statistically significant higher risk for development of seroma (OR = 6.276) and the need for revision surgery (OR = 2.452).
CONCLUSIONS: Insertion of a single drain is associated with a lower risk of SSI and wound- dehiscence, but a greater risk for seroma development that requires surgical intervention.

摘要：
背景：传统上在手术过程中插入引流管，以减少术后期间的液体积聚。引流液的出现及其数量可能是并发症的早期预测因素。多年来,已经进行了几项研究，以试图确定最佳的排水数量，从而导致低的液体积聚率和最小的生活质量损害。
目的：确定腹壁成形术中最佳的抽吸引流管数量。
方法：回顾性队列研究，分析由一名外科医生操作的所有腹部成形术患者。根据手术结束时插入的排水管数，将患者分为3组。比较两组之间的并发症发生率，并计算多变量逻辑回归模型以评估并发症的发展。
结果：七百四十三名患者被纳入本研究的分析。355例患者（45%）未插入引流管，而在255例患者（34.4％）的153例（20.6％）中插入了单个引流管2个引流管。术中插入单个引流管的患者，经历了统计学上显著的较低比率，手术部位感染（OR=0.235），增生性疤痕（OR=0.326），伤口裂开（OR=0.272），与没有排水沟的患者相比。相反,单一引流管的插入与血清肿(OR=6.276)和需要翻修手术(OR=2.452)的发生具有统计学意义的较高风险相关.
结论：插入单个引流管与较低的SSI和裂开风险相关，但血清肿发展的风险更大，需要手术干预。
