Intussusception in adults is a rare condition, and gastric cancer prolapsing into the duodenum is an even rarer phenomenon. We present a case of early gastric cancer originating in the gastric body with duodenal intussusception and discuss the clinical considerations based on the patient's overall condition and existing literature.
A 69-year-old man with a 30-mm tumor arising from the posterior wall of the gastric body was scheduled for elective surgery. During hospitalization for diabetes mellitus management, he developed sudden epigastric pain and nausea. Upper gastrointestinal endoscopy revealed tumor prolapse into the duodenum, leading to a diagnosis of ball valve syndrome. After successful endoscopic reduction, open local gastrectomy was performed. Pathological examination confirmed a well-differentiated tubular adenocarcinoma, classified as pT1b (SM2) N0M0, pStage IA.
Gastric cancer with duodenal intussusception is often early-stage and characterized by well-differentiated tubular adenocarcinoma. Depending on the patient's condition, endoscopic resection or limited surgical resection may be viable treatment options for this rare condition.
成人肠套叠是一种罕见疾病，胃癌脱垂至十二指肠更是罕见现象。我们报告一例起源于胃体部的早期胃癌伴十二指肠套叠病例，并根据患者整体状况及现有文献探讨临床考量因素。
一名69岁男性，胃体后壁有一个30毫米的肿瘤，计划进行择期手术。在因糖尿病管理住院期间，他突发上腹部疼痛和恶心。上消化道内镜检查显示肿瘤脱垂至十二指肠，诊断为球阀综合征。内镜复位成功后，进行了开放性局部胃切除术。病理检查证实为高分化管状腺癌，分类为pT1b（SM2）N0M0，p分期IA期。
伴有十二指肠套叠的胃癌通常为早期，特征为高分化管状腺癌。根据患者情况，内镜切除或有限手术切除可能是这种罕见疾病的可行治疗选择。
