腹腔镜胃局部切除术的临床应用

目的 评价腹腔镜胃局部切除术的临床应用价值.方法 回顾性分析2006年2月至2010年1月解放军总医院收治的78例行腹腔镜胃局部切除术患者的临床资料.根据病灶的位置和游离范围,采用全腹腔镜下胃局部楔形切除术、腹腔镜辅助下胃局部切除术和腹腔镜联合内镜切割吻合器肿瘤切除术.探讨患者的手术疗效.结果 78例患者均在腹腔镜下成功完成胃局部切除手术,无一例中转开腹.其中,45例行全腹腔镜胃局部楔形切除术,22例采用腹腔镜辅助下胃局部切除术,11采用腹腔镜联合内镜切割吻合器肿瘤切除术.平均手术时间为75 min(45～120 min),术中平均出血量为60 ml(35～90 ml),切除病灶平均直径为(2.5±1.3)cm(0.7～4.8 cm).术后患者无并发症发生及死亡.术后肠道功能平均恢复时间为35 h(25～42 h),术后平均住院时间为7.5 d(6～9 d).术后病理检查:63例患者为胃间质瘤;11例患者为胃良性疾病,其中异位胰腺组织5例、炎性假瘤2例、增生性息肉2例、神经鞘瘤1例、血管瘤1例;4例患者为类癌,其中位于黏膜层3例、累及深肌层1例.本组患者中位随访时间为26个月,未发现术后出血、吻合口狭窄及戳孔种植.63例胃间质瘤患者中,2例术后行甲磺酸伊马替尼治疗、1例肿瘤复发行再次手术治疗,术后恢复良好.结论 腹腔镜胃局部切除术治疗胃良性疾病、胃间质瘤及早期胃癌安全、可行.

Abstract：

Objective To evaluate laparoscopic local resection for the treatment of gastric tumors. Methods The clinical data of 78 patients who received laparoscopic local resection at the PLA General Hospital from February 2006 to January 2010 were retrospectively analyzed. According to the tumor site and free range, total laparoscopic gastrectomy was applied to 45 patients, laparoscopic local resection was applied to 22 patients, laparoscopic and endoscopic tumor resection was applied to 11 patients. The efficacies of the surgical approaches were investigated. Results Laparoscopic local resection was successfully performed on the 78 patients without conversion to open surgery. The mean operation time and operative blood loss were 75 minutes (range, 45-120 minutes) and 60 ml (range, 35-90 ml), respectively. The mean diameter of the tumor was (2.5±1.3)cm (range, 0.7-4.8 cm). No mortality or morbidity occurred postoperatively. The bowel function recovery time and the duration of hospital stay were 35 hours (range, 25-42 hours) and 7.5 days (range, 6-9 days), respectively. The results of postoperative pathological examination verified that 63 patients were with gastric stromal tumor, 11 patients were with benign gastric diseases, including 5 with gastric heterotopic pancreas, 2 with inflammatory pseudotumor, 2 with hyperplastic polyp, 1 with schwannomas and one with angioma. Four patients were with carcinoid, 3 carcinoids were located in mucous layer and 1 invaded into muscular layer. The median time of follow-up was 26 months, and no anastomotic stenosis or port-site metastasis was observed. Of the 63 patients with gastric stromal tumor, 2 were treated with imatinib mesylate, 1 had tumor recurrence and received reoperation. Conclusion Laparoscopic local resection is safe and feasible for the treatment of benign gastric neoplasms, stromal tumor and early gastric tumors.
