Bariatric surgery is routinely performed on obese women of reproductive age, most commonly with the laparoscopic sleeve gastrectomy (SG) and Roux-en-Y gastric bypass procedures (RYGB). This study analyzes the effects of postoperative pregnancy on excess BMI loss percentage (EBMIL%) after SG and RYGB. A retrospective study was conducted with 191 female patients of reproductive age between 20 and 40 years who underwent SG and RYGB performed at our institution between January 2017 and December 2018. A comparison of the results at 4-year follow-up was performed between patients who became pregnant after bariatric surgery with patients who did not. Among 191 total cases, 32 (16.7%) patients became pregnant within a 4-year follow-up period, and 159 (83.2%) patients did not. The median postoperative body mass index (BMI) in the pregnant group was 33.3 kg/m (interquartile range [IQR] 30.1-38.5) and 33.5 kg/m (IQR 28.9-38.6) in the nonpregnant group. The mean EBMIL% within a 4-year follow-up in the pregnant group was 50.4% (standard deviation [SD] 23.5) and 55.5% (SD 30.4) in the nonpregnant group. The median weight before surgery in the pregnant group was 112 kg (IQR 107.9-132.2) and 117 kg (IQR 106-132.5) in the nonpregnant group. The median weight after surgery in the pregnant group was 89.5 kg (IQR 79.5-111) and 88.9 kg (IQR 78-103) in the nonpregnant group. There was no significant difference between outcomes. Weight loss maintenance after bariatric surgery is not impacted by postoperative pregnancy within a 4-year follow-up after SG and RYGB.
减重手术通常在育龄肥胖女性中进行，最常见的手术是腹腔镜袖状胃切除术（LSG）和 Roux-en-Y 胃旁路术（RYGB）。本研究分析了术后妊娠对 LSG 和 RYGB 后超重 BMI 丢失百分比（EBMIL%）的影响。本研究为回顾性研究，纳入 2017 年 1 月至 2018 年 12 月在我院行 LSG 和 RYGB 的 191 例育龄期（20-40 岁）女性患者。比较了术后 4 年随访期间行减重手术后妊娠的患者与未妊娠的患者的结果。191 例患者中，32 例（16.7%）在 4 年随访期间妊娠，159 例（83.2%）未妊娠。妊娠组术后体质量指数（BMI）中位数为 33.3kg/m²（四分位距[IQR] 30.1-38.5），未妊娠组为 33.5kg/m²（IQR 28.9-38.6）。妊娠组术后 4 年 EBMIL%的平均值为 50.4%（标准差[SD] 23.5），未妊娠组为 55.5%（SD 30.4）。妊娠组术前体重中位数为 112kg（IQR 107.9-132.2），未妊娠组为 117kg（IQR 106-132.5）。妊娠组术后体重中位数为 89.5kg（IQR 79.5-111），未妊娠组为 88.9kg（IQR 78-103）。两组间结果无显著差异。LSG 和 RYGB 术后 4 年随访期间，术后妊娠不会影响减重手术后的体重维持。
