Major complications of sigmoid vaginoplasty: a case series.

This case series explores the major complications following sigmoid vaginoplasty in two transgender female patients. Both patients experienced significant post-operative complications, including stenosis and abscess formation, leading to sigmoid conduit ischemia and necrosis. These complications required major surgical interventions and multidisciplinary care, highlighting the complexity of these procedures and their potential morbidity. Our analysis suggests that the initial stenotic insult led to obstruction and vascular insult to the sigmoid conduit, necessitating resection of the affected bowel. The outcomes underscore the need for collaboration across specialties for optimal post-operative monitoring and management. This study advocates for future management guidelines promoting multidisciplinary collaboration to reduce morbidity and resource burdens associated with complications. Despite the complications, sigmoid vaginoplasty remains a viable gender affirmation surgery, providing an effective analogue to vaginal mucosa and offering improved neovaginal depth.

Custom 3D-printed Titanium Implant for Reconstruction of a Composite Chest and Abdominal Wall Defect.

BACKGROUND: Three-dimensional (3D) printing of implantable materials is a recent technological advance that is available for clinical application. The most common medical application of 3D printing in plastic surgery is in the field of craniomaxillofacial surgery. There have been few applications of this technology in other areas. METHODS: Here, we discuss a case of a large, symptomatic composite thoracic and abdominal defect resulting from the resection of a chondrosarcoma of the costal marginand sections of the abdominal wall, diaphragm, and sternum. The initial and second attempts at reconstruction failed, resulting in a massive hernia. Given the size of the defect, the contiguity with a large abdominal wall defect, and the high risk of recurrence, a rigid thoracic reconstruction was essential to durably repair the thoracic hernia and serve as a scaffold to which both the diaphragm and the abdominal mesh could be secured. A custom-made plate offered the most durable and anatomically accurate reconstruction in this particular clinical scenario. This technology was used in concert with a single section of coated mesh for reconstruction of the diaphragm, chest wall, and abdominal wall. RESULTS: There were no post-operative complications. The patient has improvement of his symptoms and increased functional capacity. There is no evidence of hernia recurrence 1.5 years after repair. CONCLUSIONS: 3D printing technology proved to be a useful and effective application for reconstruction of this large thoracic defect involving the costal margin. It is an available technology that should be considered for reconstruction of rigid structures with defect-specific precision.
