Can gender-affirming surgeries be safely combined? An NSQIP analysis of 30-day outcomes and case planning factors.

As gender-affirming surgeries are being performed, new techniques have been developed to meet patient desires, including recent reports of several gender-affirming procedures being combined into a single operative encounter. Such a development may provide several advantages to both patients and providers. However, it is less clear whether combining these procedures affects patient safety and surgical case planning factors. To address this, we compared the complication rates and the length of hospital stay and operative time for standalone and combined gender-affirming procedures (e.g., hysterectomy and bilateral mastectomy, breast augmentation, and vaginoplasty) performed between 2005 and 2019 in the National Surgical Quality Improvement Program database. There were 1857 standalone mastectomies, 826 standalone hysterectomies, and 30 cases where they were combined. There were 379 vaginoplasties, 648 breast augmentations, and 31 cases where they were combined. There was no evidence of differences in overall health status between those undergoing combined and standalone procedures. Two-sample proportion testing did not find significant differences in any of the complications experienced between standalone and combined procedures. Similarly, two-sample t-tests did not find significant differences in the length of the hospital stays nor in the length of the operative encounter between standalone and combined masculinizing surgeries. Combining breast augmentation and vaginoplasty, however, saved an average of 97.86 min (p = .000) of operating time. These results suggest that combining gender-affirming procedures may be a safe and viable option for individuals who desire multiple gender-affirming procedures and may even be an advantageous option for patients and practitioners alike.
