The legalization and changing perception of marijuana have led to a significant increase in its use. Although studies exploring marijuana's physiological effects have grown, its effect on surgical outcomes remains unclear. This study investigates the influence of marijuana consumption on postoperative complications in patients undergoing abdominal body contouring surgeries such as abdominoplasties and panniculectomies.
A retrospective chart review was conducted on patients who underwent abdominal body contouring procedures at an urban academic institution from 2016 to 2021. Data collected included demographic characteristics, marijuana consumption (active use, former use (last use 6 weeks prior to surgery), or never user), preoperative comorbidities, tobacco usage, operative characteristics, and postoperative complication data within 90 days.
A total of 815 patients were included, with 61 patients (7.5%) reporting active marijuana use, 31 patients (3.8%) reporting former marijuana use, and 723 (88.7%) reporting never using marijuana. The average age was 45.32 (SD 11.31), and the average BMI was 29.85 (SD 4.44). At the time of surgery, patients with any history of marijuana use had an increased risk of complications (OR=1.96; p = 0.006), and active marijuana users had a significantly higher risk of hematoma formation (OR = 3.02; p = 0.013).
Active marijuana use was significantly associated with an increased risk of postoperative hematoma formation following abdominal body contouring surgeries. These findings suggest the need for routine preoperative screening and tailored risk-reduction strategies for marijuana users.

大麻的合法化以及人们对其认知的改变导致其使用量显著增加。尽管探索大麻生理效应的研究不断增多，但其对手术结果的影响仍不明确。本研究调查大麻消费对接受腹部塑形手术（如腹壁成形术和腹壁皮肤切除术）患者术后并发症的影响。
对2016年至2021年在一家城市学术机构接受腹部塑形手术的患者进行回顾性病历审查。收集的数据包括人口统计学特征、大麻消费情况（当前使用者、既往使用者（手术前6周内最后一次使用）或从未使用者）、术前合并症、烟草使用情况、手术特征以及90天内的术后并发症数据。
共纳入815例患者，其中61例（7.5%）报告当前使用大麻，31例（3.8%）报告既往使用大麻，723例（88.7%）报告从未使用过大麻。平均年龄为45.32（标准差11.31），平均体重指数为29.85（标准差4.44）。手术时，有任何大麻使用史的患者并发症风险增加（比值比=1.96；p = 0.006），当前使用大麻的患者血肿形成风险显著更高（比值比 = 3.02；p = 0.013）。
腹部塑形手术后，当前使用大麻与术后血肿形成风险增加显著相关。这些发现表明需要对大麻使用者进行常规术前筛查并制定针对性的降低风险策略。
