目的探讨超普疝修补装置(UHS)在腹股沟疝修补术中的方法及效果。方法回顾性分析2011年4月~2013年5月本诊疗小组采用UHS行无张力修补的59例腹股沟疝患者的临床资料,所有病例行UHS疝修补时上层补片均未予以缝合固定。结果59例共72侧腹股沟疝,平均一侧腹股沟疝手术时间为(45.5±19.6)min,围术期无死亡病例,术后出现阴囊血肿1例共2侧,切口下血肿1例,切口周围青紫2例共4侧,局部异物感8例9侧,无切口感染。随访7~24个月,无复发病例,3个月后局部异物感1例共2侧,3个月后有慢性疼痛1例。结论USH在腹股沟疝修补术中可以不予缝合固定上层补片,其治疗效果确切,术后远期局部异物感及慢性疼痛发生率令人满意。

Objective To explore the method and effect of tension-free hernia repair with application of ultrapro hernia system (UHS)in inguinal hernia. Methods A retrospective analysis of the clinical data of 59 patients of inguinal hernia underwent tension-free hernia repair with UHS during the period from April 2011 to May 2013. The upper patch of UHS did not stitch. Results There was 71 cases operation in 59 patients. The average operation time was (45.5±19.6)min. There was no dead case. In al cases, there were 2 cases of scrotal hematoma in 1 patient, 1 case of incision hematoma, 4 cases of bruises around incision in 2 patients, 9 cases of local foreign body sensation in 8 patients. No incision infection occurred. Al cases were fol owed up for 7 to 24 months. There was no recurrence case. There were 2 cases of local foreign body sensation in 1 patient stil . There was 1 cases of chronic pain. Conclusion Although the upper patch of UHS do not stitch in inguinal hernia repair, its tr

目的本研究旨在探讨采用胆道修复术对胆管大范围缺损Mirizzi综合征患者进行治疗的临床疗效及安全性,为临床治疗提供参考意见。方法回顾性分析在本院行胆道修复术的22例胆管大范围缺损Mirizzi综合征患者的治疗手段和临床疗效,其中有12例采用带血管蒂胃瓣修补治疗,10例行带脐静脉瓣胆道修复术,对两组患者的一般资料、临床资料及治疗结果进行对比分析。结果两组患者的临床资料比较差异无显著性(P0.05);胃瓣修补组和脐静脉瓣修复组发生的术后并发症主要为胆管炎症,分别为4例(33.33%)和3例(30%),各组不良反应分别相加得出胃瓣修补组8例,脐静脉瓣修复组5例,两组采用Fisher精确检验得出P0.05,两组术后不良反应差异无显著性。结论对胆管大范围缺损Mirizzi综合征患者采取胆道修复术(脐静脉瓣胆道修复术、带血管蒂胃瓣修补术)均是行之有效的治疗措施,术后并发症状轻微,无死亡病例发生,可以作为Mirizzi综合征患者的首选治疗措施。

ObjectiveTo investigate the prosthesis operation of bile duct for clinical efifcacy and safety of treatment for bile duct defects in patients with Mirizzi syndrome, and provide a reference for the clinical treatment of bile duct defects in Mirizzi syndrome.MethodsA retrospective analysis of 22 cases of bile duct defects in Mirizzi under went biliary tract prosthesis syndrome treatment and clinical curative effect of the patients, including 12 cases with vascular pedicled gastriclfap for repair of treatment, 10 cases with umbilical vein graft repair of biliary tract, carries on the contrast analysis to the general data, clinical data of two groups of patients and treatment results.ResultsThe clinical data of two patients were not statistically signiifcant (P>0.05); gastric lfap in the repair group and umbilical venous lfap group,postoperative complications occurring mainly for bileduct inlfammation, were 4 (33.33%) and 3 (30%), each dystrophy respectively sum gastriclfap in the repair g

目的探讨腹股沟疝修补术治疗分别应用前入路PHS术式及后入路Kugel补片的临床效果。方法选择2006年6月~2012年6月本科室145例腹股沟疝患者,根据术式分为对照组(94例)和观察组(51例),对照组患者实施前入路PHS疝修补,观察组患者实施后入路Kugel补片疝修补,术后对比两组患者的疼痛、复发等指标。结果观察组术后24 h VAS评分为(1.83±0.81)分,随访慢性疼痛发生率为1.96%(1/51),均低于对照组的(3.26±1.47)分、7.45%(7/94),差异有统计学意义(t=5.452,P=0.009;χ2=7.276,P=0.003)。观察组阴囊肿胀发生率、局部异物感发生率低于对照组,差异有统计学意义(P0.05);两组手术时间、住院时间、恢复正常活动时间、感染率、复发率比较,差异无统计学意义(P0.05)。结论 Kugel补片后入路术式创伤小,恢复快,安全性高,不易复发,临床可选择此术式。

Objective To investigate the clinical effect of anterior PHS operation and posterior Kugel patch for inguinal hernia repair. Methods 145 cases of patients with inguinal hernia from June 2006 to June 2012 were selected,and were divided into control group (94 cases) and observation group (51 cases) according to surgical methods,control group were implemented with PHS hernia repair,observation group were implemented with Kugel mesh hernia repair,postoperative pain,relapse and other indicators were compared between two groups. Results VAS score of observation group after 24 h was 1.83±0.81,follow-up of chronic pain incidence was 1.96% (1/51),lower than 3.26±1.47 and 7.45% (7/94) of the control group,the difference was significant (t=5.452,P=0.009;χ2=7.276,P=0.003).The incidence of scrotal swelling and local foreign body sensation in observation group was lower than that of the control group,the difference was significant (P 0.05).
