Inguinal hernia repair in Hospital Authority hospitals: The role of laparoscopic hernioplasty

Objective: Two major changes have occurred in inguinal hernia repair during the last two decades: (i) the use of tension‐free mesh repair; and (ii) the application of laparoscopic technique for repair. The aims of the present study were to study: (i) how inguinal hernia repair was carried out; and (ii) the outcome of inguinal hernia repair in Hospital Authority (HA) hospitals. Methodology: This was a retrospective analysis on 8311 elective inguinal hernia repairs performed in 16 HA hospitals from January 2001 to December 2003. The mean age was 63.9 ± 14.2 years, and the male to female ratio was 22.0 : 1.0. Among these, 869 (10.5%) repairs were performed with the laparoscopic approach and 7442 (89.5%) repairs with the open approach. The proportion of laparoscopic hernia repair increased from 8.7% to 12.6%. Results: For open repair, 39% of cases were carried out with regional anaesthesia, 32% with general anaesthesia and 29% with local anaesthesia (LA). Furthermore, mesh repair was used in 88% of the patients. For laparosocpic repair, 98.4% of cases were carried out under general anaesthesia, and all patients had mesh repair using the totally extraperitoneal approach. A significantly higher proportion of bilateral repair and recurrent hernia repair was performed with the laparoscopic approach (P = 0.000). For primary unilateral repair, there was no significant difference in the postoperative length of stay (LOS) and the total LOS between the laparoscopic and the open surgery groups. No difference in LOS was found in recurrent hernia repair between the two groups. With respect to bilateral repair, both the preoperative LOS (P = 0.036) and total LOS (P = 0.039) were shorter in the laparoscopic group. Furthermore, a significantly higher proportion of day‐surgery patients was observed in the laparoscopic group than the open surgery group (21.3%vs 16.9%, P = 0.001). Nevertheless, when only the results of 2003 were analyzed, the postoperative LOS (P = 0.000) and total LOS (P = 0.000) were significantly shorter in the laparoscopic group than the open surgery group. The LOS parameters were significantly shorter in the open surgery LA subgroup compared with the non‐LA subgroup (P = 0.000), and they were not different from those in the laparoscopic group. Conclusions: The open mesh repair is the predominant approach for inguinal hernia repair in HA hospitals. The originally described local anaesthetic approach was under utilized, although it resulted in good outcome. The use of laparoscopic hernia repair is increasing and a learning curve was recently observed with improved outcome.     

改进后的腹腔镜腹腔内补片术在疝修补中的应用(附316例临床分析)

目的 腹腔镜腹腔内补片植入术(IPOM)，因有补片引起腹内组织粘连引发肠梗阻甚至复发等报道，目前争议较多，未能推广应用。作者改进了以上方法的多个步骤以克服该方法的不足。探讨改进后的方法在成人疝修补中的应用价值。方法 以缝合小儿疝的方法关闭内环口；把补片的中心固定在疝环口的中心：经腹壁用可吸收线代替钉合枪以针织的方法把补片四周牢牢地固定并展平紧贴在腹膜上。利用脐内侧韧带腹膜覆盖网片的内侧：减少网片外露的面积，减少粘连发生。结果 具有容易与腹膜相融合特性的网片能很快地与腹膜融合成一柔韧性组织，加强了疝环薄弱区，极少引起腹内肠管的粘连，更没有肠梗阻的发生，复发率低。结论 作者认为经过改进后的IPOM方法是一种效果确切、创伤少、并发症少、费用低、有微创优点。值得继续探索应用。     

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     

疝环充填式无张力疝修补术治疗腹股沟疝

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.
