摘要:目的:总结十二指肠间质瘤的诊断及外科手术体会。方法:回顾分析1999年~2008年收治的25例十二指肠间质瘤患者的临床资料。结果:临床表现最多见为黑便(14/25)，其次为右上腹不适(11/25)，腹块被(2/25)，无明显症状者(2/25)。术前诊断采用上消化道钡餐造影、CT、B超、胃镜或十二指肠镜、超声内镜检查。25例均手术治疗,其中胰十二指肠切除6例,局部切除18例,组织活检术+胃肠吻合1例。术后随访5~96个月,1、3、5年生存率为95.4%、85.5%和67.3%。结论:综合CT、胃肠道钡餐造影、消化内镜可使大部分十二指肠间质瘤术前得到确诊。手术方式依据肿瘤部位、大小而定,局部切除应选择正确重建方式。Abstract: Objective: To investigate the diagnosis and surgery treatment of duodenal gastrointestinal stromal tumors(GIST).Methods: The clinical data of 25 patients with GIST from 1999 to 2008 were analyzed retrospectively.Results: The most common symptoms of duodenal GIST were melena(14/25), as well as abdominal pain(11/25),abdominal mass, absence of symptoms(2/25). We performed the diagnosis by upper gastrointestinal radiography, gastroscopy, endoscopic ultrasonography and CT scan. All the 25 patients underwent surgical resection, of which 6 with pancreaticoduodenectomy, 18 with local resection, 1 with tissue biopsy and stomach intestinal anastomosis. With 5 to 96 months followup after operation, 1, 3 and 5year survival rates were 95.4%, 85.5% and 67.3%. Conclusion: Preoperative diagnosis of most of GIST was dependent on CT scan, upper gastrointestinal radiography and gastroscopy. The choices of surgical procedures are mainly determined by the location and size of the tumors, local excision should choose the correct way to rebulid alimentary tract.
