BACKGROUND Several reports have been published on patients with gender dysphoria and eating disorders. However, there have been few reports on the longitudinal course of eating disorders after gender reassignment surgery (GRS)/gender confirmation surgery (GCS). CASE PRESENTATION We report two Japanese cases of transsexual persons with eating disorders who underwent GRS/GCS, one male-to-female (MtF) and one female-to-male (FtM). Case 1 was a 35-year MtF person who had a 14-year-course of bulimia nervosa that developed after GRS. Case 2 was a 35-year FtM person with anorexia nervosa who underwent GCS 9 years before. CONCLUSIONS We found that the treatment of our transsexual patients influenced the course of their eating disorders for a long period, which could be attributable partly to the cultural situation in Japan, an East Asian country. It is possible that many gender identity problems and identity problems in general persist even after surgery and treatment; therefore, continual clinical support should be provided for patients with gender dysphoria and eating disorders even after hormonal therapy or GRS/GCS.

变性治疗后饮食失调的纵向过程：两例报告。

背景已经发表了几篇关于患有性别不安和饮食失调的患者的报告。然而，关于性别重新分配手术（GRS）/性别确认手术（GCS）后饮食失调的纵向病程的报道很少。案例介绍 我们报告了两例接受 GRS/GCS 的饮食失调变性人的日本病例，一例男性对女性 (MtF) 和一例女性对男性 (FtM)。病例 1 是一名 35 岁的 MtF 患者，他在 GRS 后患上 14 年的神经性贪食症。病例 2 是一名患有神经性厌食症的 35 岁 FtM 患者，他在 9 年前接受了 GCS。结论 我们发现对变性患者的治疗会长期影响他们饮食失调的病程，这可能部分归因于东亚国家日本的文化状况。即使在手术和治疗之后，许多性别认同问题和一般认同问题也可能持续存在；因此，即使在激素治疗或 GRS/GCS 之后，仍应为患有性别焦虑和进食障碍的患者提供持续的临床支持。
