泌尿外科同侧二次腹腔镜手术体会

目的 探讨泌尿外科同侧二次腹腔镜手术可行性,总结经验和体会. 方法行同侧二次腹腔镜手术患者13例.第一次手术路径:经腹膜后4例,经腹9例.第一次手术原因:肾盂输尿管连接处梗阻3例、输尿管结石3例、肾盂结石2例、肾上腺肿瘤2例、肾囊肿2例、多囊肾1例.第二次手术原因:患侧肾脏无功能4例、结石复发3例、肾囊肿复发1例、肾盂输尿管吻合处狭窄1例、同侧肾脏发生肾癌I例、多囊肾再次进展1例、肾上腺肿瘤残留和复发各1例.2次手术间隔6～72个月,平均30个月.第二次手术均取经腹入路,直视下进腹建立气腹,松解肠道粘连后打开侧腹膜及肾周筋膜,先从解剖清晰、粘连轻处按解剖层次,逐步暴露手术部位完成手术,未切除肾脏病例术后缝合肾周筋膜及侧腹膜,恢复解剖关系. 结果 第一次手术平均手术时间93 min,平均出血量70ml,平均术后住院时问4.8 d.第二次手术均顺利完成,平均手术时间97 min,平均出血量62 ml,平均术后住院时间5.0 d.第二次手术中均发现不同程度粘连和解剖位置变化,手术难度增加.二次手术后13例随访2～24个月,未发生严重并发症. 结论 选择合适病例,在熟练掌握相关技巧后,二次腹腔镜手术可以应用于有同侧泌尿外科腹腔镜手术史患者.

Experience of ipsilateral laparoseopic reoperations in urology

Objective To evaluate the feasibility and clinical results of laparoseopic reoperation for patients with history of previous ipsilateral urology laparoscopic surgeries. Methods Thirteen patients that underwent second ipsilateral urology laparoscopic surgeries were retrospectively ana-lysed. The reasons for a second operation included nonfunctional kidney after pyeloplasty, ure-terolithotomy or pyelolithotomy in 4 cases, recurrence of urinary calculi in 3 cases, pelviureteric june-tional stenosis after pyeloplasty in 1 case, recurrence of renal cyst in 1 case, recurrence of adrenal tumor in 1 case, residual adrenal tumor in 1 case, progression of polycystic kidney in 1 case and renal carcinoma after laparoscopic surgery for renal cyst in 1 case. Transperitoneal laparoscopie surgeries were performed in all cases and the first trocar was placed with open incision to avoid puncture injury. The adhesion between intestines and retroperitoneal space was dissected to expose the operative field. The lateral peritoneum and perirenal fascia were sutured after surgery in all cases except nephrectomy cases. Results For the first operation, the mean operative time was 93 min, the mean estimated blood loss was 70 ml and the average postoperative hospital stay was 4.8 d. The second operations on the 13 cases were successfully performed with mean operative time of 97 rain, mean estimated blood loss of 62 ml and average postoperative hospital stay of 5.0 d which were not significantly different from the first operation parameters(P＞0.05). During the secondary operations, adhesions and abnor-mal anatomic structure observed increased the difficulty of surgery. All patients after secondary opera-tions were followed up for 2--24 months and no major complication was observed. Conclusion La-paroscopic reoperation on patients with history of ipsilateral urology laparoscopic surgery is feasible in skilled and experienced hands and in properly selected cases.
