Gastrointestinal stromal tumors (GISTs) are rare tumors of the gastrointestinal tract accounting for less than 1% of all gut tumors. GISTs occurring in the rectum are extremely rare, and these usually present at an advanced stage compared with other sites.
A 60-year-old male who presented with features of sensations of rectal tenesmus was referred to our department with a mass in the lower rectum that was detected during a routine checkup. Colonoscopy, transrectal ultrasound, perianal magnetic resonance imaging and ultrasonic contrast were used to diagnose the rectum GIST, and then the patient underwent complete transanal resection using the ultrasonic scalpel. The patient was discharged ten days after the operation and was defined as low risk. Therefore, he had no need to receive subsequent adjuvant therapies, and he had not suffered any anal dysfunction or had any evidence of recurrence at follow up.
Surgical resection with histologically negative margins is the standard curative treatment for rectal GISTs. Appropriate surgical techniques based on the location, size, and resectability of the tumor should attract great attention from clinicians.
胃肠道间质瘤（GISTs）是胃肠道的罕见肿瘤，占所有肠道肿瘤的比例不到1%。发生在直肠的GISTs极为罕见，与其他部位相比，这些肿瘤通常在晚期出现。
一名60岁男性，因直肠坠胀感前来就诊，在常规检查中发现直肠下段有肿物，遂转诊至我科。通过结肠镜检查、经直肠超声检查、肛周磁共振成像和超声造影诊断为直肠GIST，随后患者使用超声刀进行了经肛门完整切除。患者术后十天出院，被定义为低风险。因此，他无需接受后续辅助治疗，随访期间未出现任何肛门功能障碍或复发迹象。
手术切除且切缘组织学阴性是直肠GIST的标准治愈性治疗方法。基于肿瘤的位置、大小和可切除性选择合适的手术技术应引起临床医生的高度重视。
