目的：比较吸脂联合环乳晕小切口手术与三孔腔镜治疗SimonⅡ型男性乳房发育症（GYN）的临床效果。方法：回顾性分析120例GYN病人病例资料，61例行溶脂后环乳晕小切口腺体切除手术（开放组），59例行溶脂后充气法三孔腔镜腺体切除手术（腔镜组）。比较两组手术相关指标、术后并发症发生情况及病人满意度。结果：开放组单侧手术时间短于腔镜组，单侧腺体切除量多于腔镜组，住院费用少于腔镜组（均P<0.01）。两组单侧吸脂量、术后首日引流量、引流管拔除时间比较，差异无统计学意义（P>0.05）。开放组与腔镜组并发症发生率分别为8.2%、13.6%，差异无统计学意义（P>0.05）。两组整体满意度评分差异无统计学意义（P>0.05）。结论：吸脂联合环乳晕小切口开放手术与三孔腔镜手术治疗GYN均具有较好的美容效果，开放手术操作简单、手术时间短、花费少且无特殊设备要求，适合各级医疗机构推广应用。

Objective To compare the clinical efficacy between liposuction combined with circumareolar small incision and three-port endoscopic surgery for the treatment of Simon Ⅱ gynecomastia (GYN). Methods Comparative case data of 120 patients with GYN were retrospectively analyzed, 61 patients in the open group underwent circumareolar small incision mastectomy after liposuction, and 59 patients in the endoscopic group underwent three-port endoscopic mastectomy after liposuction. The two groups were compared in terms of surgery-related indexes, occurrence of postoperative complications and patient satisfaction. Results The unilateral operation time of the open group was shorter than that of the endoscopic group, the unilateral gland resection weight in the open group was more than that in the endoscopic group, the hospitalization cost of the open group was less than that of the endoscopic group (all P<0.01). There was no significant difference in unilateral liposuction volume, drainage volume on the first postoperative day, and time to drain removal between the two groups (P>0.05). The incidence of complications in the open group and the endoscopic group were 8.2% and 13.6% respectively, and there was no significant difference between the two groups (P>0.05). The difference in the overall satisfaction scores between the two groups was not statistically significant (P>0.05). Conclusions Liposuction combined with circumareolar small incision or three-port endoscopic surgery both has good cosmetic effects in the treatment of Simon Ⅱ GYN. The operation with circumareolar small incision is simple, has a shorter operation time, costs less, and does not require special equipment, which is suitable for promotion and application in medical institutions.
