目的:探讨先天性胸骨后疝的诊断、临床特点、腹腔镜手术方法及并发症。方法:2008年12月至2018年12月首都医科大学附属北京儿童医院胸外科采用腹腔镜手术治疗24例胸骨后疝患儿，男17例，女7例；年龄8个月至4岁，平均年龄1.87岁；12例伴有其他畸形。所有患儿术前均经胸部X线片、消化道造影获得诊断，均择期行腹腔镜下胸骨后疝修补术。按手术方式的不同，分为悬吊腹腔镜组、单部位腹腔镜组和双孔腹腔镜组，比较悬吊腹腔镜组和单部位腹腔镜组在手术时间、手术出血量和术后住院时间的差异。结果:所有患儿均顺利完成手术，其中悬吊腹腔镜手术治疗8例、双孔腹腔镜1例、单部位腹腔镜手术治疗15例。将悬吊腹腔镜组与单部位腹腔镜组进行统计学比较(由于双孔腹腔镜手术例数少，且为悬吊腹腔镜和单部位腹腔镜手术中间的过渡手术方式，故未纳入比较)悬吊腹腔镜组手术时间为(76.88±29.15)min，单部位腹腔镜组手术时间为(31.47±13.44)min，差异具有统计学意义(n P<0.05)；悬吊腹腔镜组手术出血量为(2.00±1.31)ml，单部位腹腔镜组手术出血量为1.00 ml，差异具有统计学意义(n P<0.05)；悬吊腹腔镜组术后住院时间为(8.75±2.12)d，单部位腹腔镜组术后住院时间为(4.80±0.86)d，差异具有统计学意义(n P<0.05)。所有患儿均于腹腔镜下全程完成手术，无中转开腹病例。均存在疝囊，疝内容物为肝、小肠、结肠、大网膜、回盲部、阑尾。术后随访2～122个月，随访期间悬吊腹腔镜组有1例术后复发，已于我院再次行腹腔镜手术治愈。n 结论:腹腔镜手术治疗先天性胸骨后疝安全可行，单部位腹腔镜使伤口更为美观，皮下打结法减少缝合疝孔时的张力，操作简化，值得推广。“,”Objective:To explore the clinical features, laparoscopic repairing and outcomes of children with Morgagni hernia (MH).Methods:From 2008 to December 2018, 24 MH children at a single pediatric hospital were retrospectively reviewed. Clinical presentations, surgical approaches and outcomes were evaluated. There were 17 boys and 7 girls with a median diagnostic age of 1.87(2/3-4) years. Associated anomalies were present in 12/17. Intraoperative hemorrhage, operative duration and postoperative hospitalization stay were compared between gasless laparoscopic and single-site umbilical laparoscopic groups.Results:The procedures were gasless laparoscopy (n=8), two-site umbilical laparoscopic repair (n=1) and single-site umbilical laparoscopic repair (n=15); The mean operative duration was (76.88±29.15) versus (31.47±13.44) min in gasless laparoscopic and single-site umbilical laparoscopic groups. And the difference was statistically significant (n P<0.05). The mean intraoperative hemorrhage was (2.00±1.31)versus 1.00 ml and the difference was significant (n P<0.05); the mean postoperative hospitalization length was (8.75±2.12) versus (4.80±0.86) days and the difference was statistically significant (n P<0.05). All children underwent full-thickness abdominal wall repair and none had a conversion into open surgery. Hernia sacs were not resected. Colon was the most commonly herniated organ. There was one recurrence in gasless laparoscopic group during a follow-up period of 2-122 months.n Conclusions:Laparoscopic-assisted MH repair is a safe and effective treatment for single-site umbilical and full-thickness abdominal wall repair. This simple mini-invasive procedure is well-tolerated and worthy of a wider popularization.
