Summary

Surgeons from the Amsterdam gender clinic reviewed studies published from 1995 onwards on ways to surgically create a vagina in trans women. They found 26 studies. Almost all looked back at patients of a single surgical team, covering 1,461 operations using penile skin and 102 using a piece of bowel. Narrowing of the new vagina was the most common problem with both methods. Sex life and satisfaction were judged generally acceptable, but every study measured them differently, and only one measured quality of life. The authors concluded that the penile skin method is the best studied, the bowel method does not seem worse, and better-planned studies that follow patients forward with standard measures are essential. In plain terms, the review shows how weak the evidence was: it cannot reliably say how often problems or dissatisfaction happen, or which method is better.

Key findings

• 回顧在兩個醫學資料庫中檢索 1995 年以來的研究，納入 26 項關於跨性別女性陰道成形術結果的研究。
• 多數研究是回顧外科醫師過去患者的低品質或普通品質報告，沒有對照組。
• 陰莖皮膚法的結果在 1,461 人身上有報告，腸道法則只有 102 人。
• 兩種方法最常見的問題都是新陰道的狹窄或閉合。
• 性生活和滿意度被描述為整體可接受，但各研究使用了許多不同的問卷，通常是從未經準確度檢驗的問卷。
• 26 項研究中只有一項報告了手術後的生活品質。
• 作者的結論是，標準的方法以及及時往前追蹤患者的研究，對於判斷和比較陰道成形術的結果至關重要。

Abstract

INTRODUCTION: Gender reassignment surgery is the keystone of the treatment of transgender patients. For male-to-female transgenders, this involves the creation of a neovagina. Many surgical methods for vaginoplasty have been opted. The penile skin inversion technique is the method of choice for most gender surgeons. However, the optimal surgical technique for vaginoplasty in transgender women has not yet been identified, as outcomes of the different techniques have never been compared.

AIM: With this systematic review, we aim to give a detailed overview of the published outcomes of all currently available techniques for vaginoplasty in male-to-female transgenders.

METHODS: A PubMed and EMBASE search for relevant publications (1995-present), which provided data on the outcome of techniques for vaginoplasty in male-to-female transgender patients.

MAIN OUTCOME MEASURES: Main outcome measures are complications, neovaginal depth and width, sexual function, patient satisfaction, and improvement in quality of life (QoL).

RESULTS: Twenty-six studies satisfied the inclusion criteria. The majority of these studies were retrospective case series of low to intermediate quality. Outcome of the penile skin inversion technique was reported in 1,461 patients, bowel vaginoplasty in 102 patients. Neovaginal stenosis was the most frequent complication in both techniques. Sexual function and patient satisfaction were overall acceptable, but many different outcome measures were used. QoL was only reported in one study. Comparison between techniques was difficult due to the lack of standardization.

CONCLUSIONS: The penile skin inversion technique is the most researched surgical procedure. Outcome of bowel vaginoplasty has been reported less frequently but does not seem to be inferior. The available literature is heterogeneous in patient groups, surgical procedure, outcome measurement tools, and follow-up. Standardized protocols and prospective study designs are mandatory for correct interpretation and comparability of data.
