Review Indications, outcomes, and complications of neoumbilical reconstruction: A systematic review

Background and objectives: Neoumbilicoplasty aims to reconstruct an aesthetically pleasing new umbilicus following agenesis, malignancy, anatomical distortion, or umbilicus loss. Despite the wide variety of surgical techniques described, literature is scarce when it comes to standardized categorization of these as well as the clear definition of patients' selections, specific indications, final outcomes, and possible complications. According to available literature, this work aims to evaluate different surgical approaches, and correlate them to specific surgical needs, to simplify the surgical choice and patient management.Methods: A systematic review was performed in December 2020 in PubMed, Web of Science, and MedLine Ovid databases according to the PRISMA guidelines. Results: A total of 41 studies and 588 patients were finally included. On the basis of the evidence of the literature collected, we divided the studies into four groups according to the neoumbilicoplasty techniques: single suture or purse-string suture, single flap, multiple flap, and skin graft. Patients' surgical comorbidities, neoumbilicoplasty indications, and aesthetic and surgical outcomes were investigated. Direct suture and single and multiple flap techniques assured overall, satisfactory cosmetic outcomes with a low rate of surgical complications.Whereas suture-only techniques were chosen mostly by general surgeons/urologists in laparo- scopic surgery, the single flap was the preferred method to reconstruct the umbilicus in open abdominal surgery or combined abdominoplasty with herniorrhaphy. Multiple flap and skin grafts were adopted in abdominoplasty-related umbilicus reconstruction, although the latter option showed impactful aesthetic and surgical complications. Conclusions: Umbilicoplasty can assure generally pleasant aesthetic outcomes with relatively low complication rates. Indications for specific techniques correspond to different patient populations and surgical scenarios.(c) 2023 British Association of Plastic, Reconstructive and Aesthetic Surgeons.
