The use of three different mesh materials in the treatment of abdominal wall defects

Abstract Abstract. Various prosthetic materials have been proposed for the repair of abdominal wall defects. These materials offer tension-free repair and significantly lower recurrence rate. Their respective properties are related to such complications as seroma, infection, fistula formation, intestinal adhesions and removal. We compared the final outcome in treating abdominal wall defects in 56 patients with three different prosthetic materials: conventional polypropylene in a preperitoneal location, expanded polytetrafluoroethylene mesh, and hydrophilic membrane coated polyester mesh in an intraperitoneal location. The hydrophilic coated polyester group exhibited the lowest complication rate and the polypropylene group the highest. Electronic Publication     

Long-term result and current status of the Lichtenstein open tension-free hernioplasty

Summary The tension-free hernioplasty project began in 1984 at the Lichtenstein Hernia Institute. The method consists of complete reinforcement of the inguinal floor with a large sheet of mesh, with adequate mesh tissue interface beyond the boundary of the inguinal floor and creation of a new internal ring made of prosthesis. The preliminary report of this operation was published in 1989, with no recurrence at that point in time. Shortly after the submission of the report, several recurrences were encountered. Based on the lesson learned from those recurrences, the operation was slightly modified and reported in 1991 [Amid 1993]. Since then, the Lichtenstein technique has gained world-wide popularity. Outcome measures identical to ours and other authors have been achieved by even those surgeons who have no special interest or expertise in herniology. The purpose of this article is to report the current state of the open tension-free hernioplasty for the repair of primary and recurrent inguinal hernias.     

Structure and Concentration Capacity of the Kidneys in Brattleboro Rats under Conditions of Long-Term Vasopressin Treatment

Endoprostheses made from knitted fabric of 3 loop types were used for hernioplasty in rats. Biocompatibility of implanted textile constructions was evaluated after 6 months. The intensity of inflammatory reaction and types of complications in animals depended on the loop type and method of finishing of the mesh endoprosthesis tissue. __________ Translated from Byulleten’ Eksperimental’noi Biologii i Meditsiny, Vol. 145, No. 5, pp. 582–587, May, 2008

Comparative study of open tension-free and laparoscopic inguinal hernia repair in hernioplasty and simultaneous laparoscopic cholecystectomy

Objective: To evaluate the clinical value of laparoscopic inguinal hernia repair in hernioplasty and simultaneous cholecystectomy. Methods: Twenty-eight patients with symptomatic chronic calculous cholecystitis and synchronous unilateral primary inguinal hernia were performed combined surgery between October 2001 and March 2005. Of them, 10 cases underwent laparoscopic totally extraperiloneal mesh hernia repair (TEP) and laparoscopic cholecystectomy (LC), 3 cases underwent laparoscopic transabdominal preperitoneal mesh hernia repair (TAPP) and LC, and 15 cases underwent LC and open tension free hernia repair. Results: All the procedures were performed successfully, 2 patients occurred urinary retention in LC + open group and 1 patient occurred scrotum seroma in LC + TEP procedures. During the 6 to 24 months' follow-up, no hernia recurrences occurred in all patients. There were 6 patients (40%) in LC + open group had discomfort pain in the inguinal region and lasted 1 to 3 months. The operating time was longer in the totally laparoscopic group (TEP + LC and TAPP + LC) (104±31 min) than in the LC+open group (80±28 min) (P<0. 05). The intensity of postoperative pain at rest was greater in the LC + open group at 24 h (P<0. 05) and 48 h (P<0. 05). No differences between the 2 groups were found in the mean operating costs and oral intake of the postoperative period. But the time resume to walking (2. 9 vs 1. 8 d) (P<0. 01) and the mean hospital stay (8. 2 vs 4. 6 d) (P<0. 001) was longer in the LC + open group than in the totally laparoscopic group. Conclusion: In the same operating costs, the totally laparoscopic precedure has more advantages of low postoperative pain, quicker resume to walking and less hospital stay than open tension-free hernia repair in hernioplasty and simultaneous LC. Thus, the totally laparoscopic approach is considered to be advantage of the hernioplasty and simultaneous LC.     

腹膜前间隙疝修补术与常规疝环填充式修补术的临床效果对比分析

目的探讨腹膜前腹膜前间隙疝修补术与传统疝环填充式修补术的临床治疗效果的优缺点,以便指导临床实践。方法将我院2009年10月-2013年4月收治的84例腹股沟疝患者,按照随机对照原则分为试验组与对照组,试验组42例患者采取腹膜前间隙疝修补术的治疗方法,对照组42例患者采用疝环填充式修补术治疗方法,比较两组患者临床效果及不良反应。结果试验组的手术时间及患者疼痛时间明显低于对照组（P〈0.05）;试验组患者局部异物感的发生率及伤口麻木感的发生率均显著低于实验组（P〈0.01）。结论采用腹膜前间隙疝修补术治疗腹股沟疝的临床效果显著,而且不良反应小,值得临床推广。     

无张力疝修补术后疼痛的临床分析

目的探讨无张力疝修补术后慢性疼痛的产生原因。方法对我院近年行腹股沟疝无张力修补术后部分病例产生慢性痛疼的原因的临床资料回顾性分析。结果研究结果表明无张力疝气修补术后疼痛发生率为9.66%;372例首次疝患者疼痛发生率为4.30%,125例复发疝患者中疼痛发生率为25.6%,复发疝术后疼痛发生率明显高于首次疝(χ2=47.95,P=0.001);Ⅰ型疝、Ⅱ型疝、Ⅲ型疝、Ⅳ型疝发生率分别为5%,6.21%,13.93%和20%,随着疝气程度的增加疼痛发生率呈现明显上升趋势,各组间直接存在明显差异(χ2=17.10,P=0.001);174例采用局部浸润麻醉患者中疼痛发生率为17.82%;323例采用硬膜外麻醉患者疼痛发生率为5.26%,局部浸润麻醉术后疼痛发生率明显高于硬膜外麻醉(χ2=20.42,P=0.001);神经切断、未保护神经、神经暴露并保护组疼痛发生率分别为13.33%,16.34%,5.28%,各组之间比较存在显著统计学差异(χ2=14.99,P=0.001);多因素分析发现疝气复发(OR=1.429,95%CI:1.150~2.057)、Ⅳ型(OR=1.889,95%CI:1.247~2.900)、局部浸润麻醉(OR=1.586,95%CI:1.184~1.832)、术后未保护神经(OR=2.197,95%CI:1.110~4.349)为疝气术后发生疼痛的独立危险因素。结论疝气复发、疝气类型、麻醉方式、手术方式均对无张力疝气修补术后疼痛的发生具有重要影响,为减少术后疼痛的发生应针对不同的类型采取不同的手术和麻醉方式。
