BACKGROUND
The most common curative treatment for gastrointestinal stromal tumors (GISTs) is local excision. For rectal GISTs, however, local excision is difficult because of the anatomical features of the rectum. The optimal surgical approach is still under debate, and less invasive methods are desired. We herein report a case of transvaginal resection of a rectal GIST in a young woman.
CASE PRESENTATION
A 21-year-old woman was diagnosed with a resectable GIST in the anterior rectal wall and underwent transvaginal tumor resection. The posterior vaginal wall was incised, revealing the tumor fully covered by the rectal mucosa. The rectal adventitia and muscular layer were incised, and the tumor was resected en bloc without rupture. The postoperative course was favorable, and the patient was discharged on postoperative day 12. No findings consistent with recurrence were present 6 months postoperatively.
CONCLUSION
Transvaginal tumor resection is a treatment option as a minimally invasive procedure for GISTs in the anterior rectal wall in female patients.
背景
胃肠道间质瘤（GISTs）最常见的治愈性治疗方法是局部切除。然而，对于直肠GISTs，由于直肠的解剖结构特点，局部切除较为困难。最佳手术方式仍存在争议，人们期望采用侵入性较小的方法。我们在此报告一例年轻女性直肠GIST经阴道切除术的病例。
病例介绍
一名21岁女性被诊断为直肠前壁可切除的GIST，并接受了经阴道肿瘤切除术。切开阴道后壁，发现肿瘤完全被直肠黏膜覆盖。切开直肠外膜和肌层，完整切除肿瘤且未破裂。术后病程顺利，患者于术后第12天出院。术后6个月未发现复发迹象。
结论
经阴道肿瘤切除术是女性患者直肠前壁GISTs的一种微创治疗选择。
