Recurrent inguinal hernia: randomized multicenter trial comparing laparoscopic and Lichtenstein repair

Background The optimal treatment for recurrent inguinal hernia is of concern due to the high frequency of recurrence. Methods This randomized multicenter study compared the short- and long-term results for recurrent inguinal hernia repair by either the laparoscopic transabdominal preperitoneal patch (TAPP) procedure or the Lichtenstein technique. Results A total of 147 patients underwent surgery (73 TAPP and 74 Lichtenstein). The operating time was 65 min (range, 23–165 min) for the TAPP group and 64 min (range, 25–135 min) for the Lichtenstein group. Patients who underwent TAPP reported significantly less postoperative pain and shorter sick leave (8 vs 16 days). The recurrence rate 5 years after surgery was 19% for the TAPP group and 18% for the Lichtenstein group. Conclusion The short-term advantage for patients who undergo the laparoscopic technique is less postoperative pain and shorter sick leave. In the long term, no differences were observed in the chronic pain or recurrence rate.     

Randomised study of Lichtenstein compared with Shouldice inguinal hernia repair by surgeons in training.

OBJECTIVE: To compare the outcome following Lichtenstein open mesh technique or Shouldice repair for inguinal hernia operated on by surgeons in training. DESIGN: Prospective, randomised, trial. SETTING: District hospital, Sweden. SUBJECTS: 200 men with primary inguinal hernias. INTERVENTIONS: Lichtenstein mesh repair or Shouldice repair. MAIN OUTCOME MEASURES: Duration of operation, postoperative pain assessed by visual analogue scale (VAS), complications within 30 days, duration of sick leave, and recurrence within one year. RESULTS: 178 patients were available for evaluation (n = 89 in each group). There were no significant differences in duration of operation, pain score, or incidence of postoperative complications. Patients in the mesh group took significantly less sick leave (mean 18.2 days) than those in the Shouldice group (23.8 days, p<0.05). The number of recurrences differed significantly between the groups with 9 in the Shouldice group and none in the mesh group (p<0.01). CONCLUSION: For surgeons in training the Lichtenstein open mesh technique is a better method of inguinal hernia repair than the Shouldice technique. The outcome is better for the patients and it is more cost-effective.     

The effects of different hernia repair methods on postoperative pain medication and CRP levels

Although tension-free techniques of hernia repair using synthetic meshes have yielded encouraging results, the best method of inguinal hernia repair is still unclear. The aim of this study was to compare the responses of inflammatory mediators and postoperative pain relief following laparoscopic total extraperitoneal (TEP) hernioplasty, open tension-free mesh hernioplasty (Lichtenstein), posterior preperitoneal mesh hernioplasty (Nyhus procedure), and Bassini procedure. Patients with primary inguinal hernia were randomized in the operating room to undergo one of these repair techniques. Group I comprised 24 patients treated by Lichtenstein procedure; Group II comprised 21 patients treated by Nyhus procedure; Group III comprised 19 patients treated by Bassini procedure; and Group IV comprised 20 patients treated by laparoscopic TEP mesh hernioplasty. Postoperative pain levels following hernia repair were compared by measuring the use of patient-controlled analgesia (PCA) during the 24 hours after surgery. Serum samples withdrawn before surgery and 48 hours after surgery were assayed for C-reactive protein (CRP) content. Patient characteristics, operating time, and operative and early complications were noted. Serum CRP levels rose markedly following Nyhus (184.5 +/- 41.6 mg/L), Lichtenstein (138.4 +/- 72.5 mg/L), and Bassini repair (137.2 +/- 55.9 mg/L) compared with that of patients who underwent TEP mesh hernioplasty (55.5 +/- 41.2 mg/L). There were also significant differences in the postoperative need for analgesics via PCA among patients undergoing Nyhus (382.9 +/- 189.1 mg), Bassini (303.2 +/- 173.7 mg), and Lichtenstein (253.9 +/- 129.3) procedures compared with 196.6 +/- 148.8 mg for the TEP mesh hernioplasty group. Patients in the Lichtenstein group also had significantly less need of analgesics than those in the Nyhus and Bassini groups. In conclusion, TEP mesh hernioplasty is less traumatic and yields less postoperative pain than the Nyhus, Lichtenstein, and Bassini procedures.     

Day-case endoscopic totally extraperitoneal inguinal hernioplasty versus open Lichtenstein hernioplasty for unilateral primary inguinal hernia in males

Background Endoscopic totally extraperitoneal inguinal hernioplasty (TEP) is an accepted technique for the repair of recurrent and bilateral inguinal hernia, but its role in the management of unilateral primary inguinal hernia remains controversial. The current randomized trial was undertaken to compare the postoperative and 1-year outcomes of day-case TEP and open Lichtenstein hernioplasty for unilateral primary inguinal hernia in males. Methods From January 2002 to January 2004, a total of 200 male patients were randomized to undergo either day-case unilateral TEP or open Lichtenstein hernioplasty under general anesthesia. The primary outcome measures included postoperative pain score, time until return to work, incidence of chronic groin pain, and recurrence rate 1 year after the operation. Results All TEP procedures were successfully performed without conversion. The mean operation time for TEP (50±13.2 min) was significantly shorter than for open Lichtenstein hernioplasty (58 ± 17.6 min) (p < 0.001). The pain score at rest was significantly lower in the TEP group than in the open group on postoperative days 0, 1, 4, 5, and 6. On the average, the patients returned to work 8.6 days after TEP and 14 days after Lichtenstein hernioplasty (p = 0.006). Postoperative recovery and morbidity rates were otherwise comparable between the two groups. The incidence of chronic groin pain 1 year after TEP (9.9%) was significantly lower than after open surgery (21.7%) (p = 0.032). None of the patients in either group showed recurrence at the last follow-up assessment. Conclusions Day-case TEP was superior to open Lichtenstein hernioplasty for the repair of unilateral primary inguinal hernia in males. The benefits of day-case TEP included less postoperative pain, a faster return to work, and a lower incidence of chronic groin pain.     

Safety and efficacy in inguinal hernia repair: a retrospective study comparing TREPP,TEP and Lichtenstein (SETTLE)

Background

This pilot trial investigates whether the trans rectus sheath extra-peritoneal (TREPP) mesh repair is a safe and effective procedure compared to the currently most performed inguinal hernia repair techniques TEP and Lichtenstein.

Methods

Three hundred patients older than 18 years with unilateral inguinal hernia were included in this retrospective cohort study, of which 58 (19.3%) underwent TREPP, 190 (63.3%) TEP and 52 (17.3%) Lichtenstein. The primary outcome of this study was inguinal hernia recurrence rate within 1 year after surgery. Secondary objectives were chronic post-operative inguinal pain (CPIP) lasting more than 6 months, (major) complication rates and operating time.

Results

Recurrence rate within 1-year post-operative was low overall in the study population and did not differ significantly between TREPP, TEP and Lichtenstein, respectively 1.7, 2.1, 0.0% (P?=?0.591). The rate of CPIP for which the patient contacted the hospital was similar in the study groups: TREPP: 1.7%; TEP: 1.6%; Lichtenstein: 1.9%; (P?=?0.591). The mean operating time in minutes (SD) was significantly shorter in the TREPP group compared with the two other patient groups (TREPP: 22.2 (±?5.7); TEP: 38.7 (±?14.8); Lichtenstein: 49.3 (±?17.1), P?<?0.001). No major complications occurred in any patient of the study groups.

Conclusion

TREPP seems to be an effective and safe technique for unilateral primary inguinal hernia repair. It is found to be comparable to TEP and Lichtenstein in terms of recurrence rates, chronic post-operative inguinal pain, and clinically significant adverse events. This pilot study proves the need for future research into the TREPP technique.

     

Laparoscopic extraperitoneal inguinal hernia repair versus open mesh repair: a prospective randomized controlled trial

BACKGROUND: This study was designed to compare an open tension-free technique (Lichtenstein repair) with a laparoscopic totally extraperitoneal hernia repair (TEP). METHODS: One hundred sixty-eight men aged 30 to 65 years with primary or recurrent inguinal hernia were randomized to TEP or open mesh technique in the manner of Lichtenstein. Follow-up was after 1 and 6 weeks, and 1 year. RESULTS: Eighty-one patients were randomized to TEP, and 87 to open repair. For 1 patient in each group, the operation was converted to a different type of repair. No difference was seen in overall complications between the 2 groups. However, 1 patient in the TEP group underwent operation for small bowel obstruction after surgery. A higher frequency of postoperative hematomas was seen in the open group (P <.05). Patients in the TEP group consumed less analgesic after surgery (P <.001), returned to work earlier (P <.01), and had a shorter time to full recovery (P <.01). Two recurrences occurred in the TEP group 1 year after surgery. CONCLUSION: The TEP technique was associated with less postoperative pain, a shorter time to full recovery, and an earlier return to work compared with the open tension-free repair. No difference was seen in overall complications. However, 2 recurrences did occur after 1 year in the TEP group.     

Laparoscopic totally extraperitoneal hernia repair versus open Lichtenstein hernia repair: results and complications

Whereas open Lichtenstein inguinal herniorrhaphy is generally accepted as a safe, well-understood method with a high success rate, the laparoscopic repair of a inguinal hernia is a fairly recent technique. Although the laparoscopic approach to a hernia repair procedure is associated with less pain and faster recovery than open repair, many surgeons are not familiar with this technique owing to technical demands and a long learning curve. This study compares the results and complications between open tension-free mesh (Lichtenstein) repair and laparoscopic total extraperitoneal (TEP) repair. The study cohort was comprised of 345 consecutive patients who underwent an inguinal herniorraphy procedure. An open hernia repair was performed on one group of patients (n = 233), whereas TEP repair was performed on the other (n = 112), and then the comparison of intra- and postoperative complications and results obtained from both techniques was done. The mean hospital stay was similar in both groups. The average operative time in the TEP group was 58.6 +/- 18.1 minutes, and the average operative time in the open group was 58.2 +/- 17.8 minutes. There was no difference in postoperative complication rates between the two groups, except for urinary retention, which patients who underwent TEP repair were more likely to get. The following major complications were recorded: 2 cases of urinary bladder perforation-1 during TEP repair and the other during Lichtenstein repair, but both with good postoperative outcome-and 1 case of pneumothorax, which occurred during the TEP procedure. Despite the fact that TEP is a demanding procedure, it may be performed efficiently with an acceptable operating time and a low complication rate.     

完全腹膜外疝修补术与Lichtenstein术治疗腹股沟疝的疗效比较

目的探讨腹腔镜完全腹膜外疝修补术（TEP）与Lichtenstein术治疗腹股沟疝的临床疗效及并发症影响。 方法回顾性分析2018年6月1日至2021年6月1日中国人民解放军联勤保障部队第967医院普外科收治的126例腹股沟疝患者临床资料。74例患者接受TEP手术,为TEP组;52例接受Lichtenstein术,为开放组;对比2组手术相关指标、术后1周并发症（阴囊水肿、切口感染、尿潴留、暂时性神经感觉异常）发生率及术后不同时间腹股沟区视觉模拟评分（VAS）。 结果TEP组手术时间、住院费用明显高于开放组,术中出血量、住院时间,术后1周并发症（阴囊水肿、切口感染、尿潴留、暂时性神经感觉异常）发生率明显低于开放组,差异有统计学意义（P均<0.05）。术后24 h及1、3个月腹股沟区VAS评分明显低于开放组,差异有统计学意义（P均<0.05）;但术后6个月VAS评分与开放组相比差异无统计学意义（P>0.05）。 结论TEP手术具有创伤小、疼痛轻、恢复快、住院时间短、并发症发生率低的特点,治疗效果明显优于Lichtenstein术,但其费用高、手术用时长,临床应用中应根据患者自身情况及手术医师所掌握的手术技能选择合适的手术方式。     

Randomized controlled study of laparoscopic total extraperitoneal versus open lichtenstein inguinal hernia repair

BACKGROUND: Whereas open anterior inguinal herniorrhaphy is a time-tested, safe, and well-understood operation with a high success rate, laparoscopic techniques of inguinal hernia repair are fairly recent. Consequently, short- and long-term outcomes are still being evaluated. Few studies have compared laparoscopic extraperitoneal inguinal hernia repair with tension-free open hernia repair. The current study was conducted to compare complications, operative time, postoperative pain, length of hospital stay, and return to work between open tension-free mesh Lichtenstein (open) repair and laparoscopic total extraperitoneal (TEP) repair. METHODS: In a prospective randomized study, open hernia repair was performed in one group (n = 25), and TEP repair using a large mesh was performed in another (n = 25). Then intraoperative and postoperative complications and results were compared. RESULTS: The mean operative time in the TEP group was 75.72 +/- 31.6 min, which was significantly longer than the mean operative time in the open group (54 +/- 15) min (p <0.001). The mean pain scores in the TEP group were 2.64 +/- 1.4 at 12 h and 1.76 +/- 1.4 at 24 h. These scores were significantly lower than the corresponding scores of 3.52 +/- 1.7 (p <0.04) and 2.74 +/- 1.5 (p <0.01) in the open repair group. The mean postoperative analgesic dose was 2.6 +/- 2.3 in the TEP group, which was significantly lower than in the open group 5.76 +/- 3.5 (p <0.001). There was no major complication in either group. The time until return to work was significantly lower in the TEP group (12.8 +/- 7.1) days versus 19.3 +/- 4.3 days; than in the open group (p <0.001). In terms of cosmetics, all 25 patients (100%) in TEP group rated themselves as "highly satisfied," as compared with 7 patients (28%) in the open group (p <0.001). After a mean follow-up period of 13 months (range, 9-18 months), no recurrence was seen in either of the two groups. CONCLUSION: In terms of complications and short-term recurrence, TEP repair is comparable with open repair. Moreover, TEP is significantly less painful in the early postoperative period, leading to earlier ambulation than open repair. Additionally, TEP results in significantly earlier return to work and better cosmetic results. Currently, TEP seems to be a better alternative than the existing open repair, provided the long-term recurrence rates are comparable. Despite the fact that TEP was a new procedure for the surgeon and the study was conducted during the learning phase, the results are comparable with those in the world literature.     

腹腔镜下不同术式与开放手术疝修补术治疗腹股沟疝的疗效

目的比较腹腔镜下经腹腔腹膜前疝修补法（TAPP）、完全腹膜外疝修补法（TEP）与开放式无张力疝修补术（Lichtenstein）治疗腹股沟疝的疗效及安全性。 方法选择2015年3月至2017年8月就诊于松滋市人民医院的150例腹股沟疝患者,按照随机数字表法分为3组,Lichtenstein组、TAPP组、TEP组,各50例。对比3组手术相关指标、并发症及术后6个月复发率,并观察围手术期患者应激反应[皮质醇（Cor）、去甲肾上腺素（NE）、醛固酮（ALD）]变化。 结果3组手术时间、术后并发症发生率比较,差异均无统计学意义（P>0.05）;Lichtenstein组术中出血量、术后12 h疼痛数字评分（NRS）、术后下床活动时间及住院时间均比TAPP组和TEP组高,住院费用比TAPP组和TEP组低,差异有统计学意义（P<0.05）;TEP组术后12 h NRS评分、术后下床活动时间及住院费用比TAPP组低,差异有统计学意义（P<0.05）;Lichtenstein组术后3 d Cor、NE及ALD水平,复发率比TAPP组和TEP组高,差异均有统计学意义（P<0.05）。 结论Lichtenstein术治疗腹股沟疝操作相对简单、费用低,腹腔镜下TAPP、TEP术具有应激创伤小、疼痛轻、并发症少、复发率低等特点,临床应结合患者具体病情选择适宜的手术修补方式。     

Randomized clinical trial of Lichtenstein patch or Prolene Hernia System for inguinal hernia repair

BACKGROUND: In this randomized prospective study the short- and long-term outcomes of patients undergoing inguinal hernia repair with either Lichtenstein mesh or the Prolene Hernia System (PHS) were evaluated. METHODS: Postoperative pain and time to return to work, driving and sporting hobbies were recorded after 300 inguinal hernia repairs done by one of the two methods. Long-term sequelae and complications were assessed at follow-up visits 1 week, 1 month and 1 year after the operation. RESULTS: The median duration of operation for unilateral primary hernia was 37 min for the Lichtenstein operation and 27 min for the PHS procedure (P < 0.001). Postoperative pain was similar after both operations. Median sick leave was 7 days in both groups. Time to driving a car was 4 versus 3 days, and time to return to sporting hobbies 13 versus 11 days, in the Lichtenstein and PHS groups, respectively. Apart from a residual femoral hernia after Lichtenstein repair, no recurrent inguinal hernias were detected. CONCLUSION: Both Lichtenstein and PHS methods resulted in rapid recovery and low recurrence rates. The PHS operation was significantly quicker.     

Laparoscopic total extraperitoneal repair versus anterior preperitoneal repair for inguinal hernia

Laparoscopic inguinal hernia repair is still not the gold standard for repair although mesh implantation is unequivocally accepted as an integral part of any groin hernia repair. The aim of the study was to compare the results of anterior preperitoneal (APP) mesh repair with totally extra peritoneal (TEP) repair for inguinal hernias. The prospective study was conducted on 241 patients with 247 hernias (from January 2000 to June 2004). Anterior preperitoneal repair was done in 121 patients and 120 patients were subjected to TEP repair. Repair in both groups was done by using Prolene mesh of size 6×4 in. or 6×6 in. intraoperative and postoperative parameters and complications were recorded and the patients were followed up to 1 year post-surgery. For both unilateral and bilateral inguinal hernias, mean operative time was significantly more in patients of TEP repair as compared to APP repair (P<0.001) and significantly more patients had peritoneal tears in the TEP group (P<0.001). Patients undergoing TEP repair, however, had significantly less postoperative pain (P<0.05) and postoperative hospital stay (P<0.05) and return to work was significantly earlier is this group (P<0.01 and P<0.001). There was no difference in the recurrence rate between the two groups. Patients with inguinal hernias undergoing laparoscopic repair recover more rapidly, and have less incidence of postoperative pain. But it takes significantly more time to perform than APP repair and also the incidence of peritoneal tear is higher.     

腹腔镜完全腹膜外腹股沟疝修补术与Lichtenstein修补术的比较

目的对比腹腔镜完全腹膜外腹股沟疝修补术与Lichtenstein修补术的临床疗效。方法选择2008年4月至2009年5月245例腹股沟疝患者,随机分成两组,TEP组行腹腔镜全腹膜外腹股沟疝修补术,Lichtenstein组行Lichtenstein修补术。对比两组患者手术时间、平均住院时间、住院费用、平均恢复正常活动时间以及近远期并发症等指标,评价两种手术方式的疗效。结果 TEP组行单侧疝修补术的手术时间长,平均住院费用高,术中中转手术方式比例高,但恢复正常活动时间短,术后近远期并发症少。结论尽管TEP术存在手术时间长、住院费用高、术中中转手术概率高等缺点,但术后疼痛少,恢复正常活动时间短,对于有经验的外科医生应作为首选术式。     

The economic impact of laparoscopic inguinal hernia repair: results of a double-blinded,prospective, randomized trial

For this study, 66 patients with a preoperative diagnosis of unilateral primary inguinal hernia were randomized to undergo laparoscopic totally extra peritoneal (TEP), laparoscopic transabdominal (TAPP), or open inguinal hernia repair with polypropylene mesh (Lichtenstein type). Both the operative team caring for the patient postoperatively and the patient were blinded to the operative approach by placement of a large dressing covering the abdomen, which was not removed until postoperative day 3. The patients recorded their pain level on a visual analog pain scale daily. Medication usage also was recorded. All patients were seen at 7-day intervals until they returned to work. The patients were interviewed during their postoperative visits by an investigator blinded to the operative approach and questioned regarding their ability to return to work and their pain levels. The average number of lost work days in all the groups was 12, and there was no significant difference between the three groups (p = 0.074). The average operating time for the TAPP procedure was 59 min, less than the time required to complete either the TEP or the Lichtenstein approach, which had equivalent operative times (p = 0.027). The material cost was significantly lower for the Lichtenstein repair ($1,200 less) than for either of the laparoscopic approaches, a saving primarily related to consumable operating room supplies. The TEP repair costs were minimally higher than those for the TAPP repair ($125 more). No significant differences were noted in the postoperative pain scales, and the use of postoperative oral analgesics was equivalent. The higher operative costs noted for the laparoscopic hernia repairs were not offset by a shortened convalescence. Postoperative pain appears to be equivalent regardless of the operative approach chosen and is easily managed with oral analgesics.

Lichtenstein疝修补术和网塞修补术治疗原发性腹股沟疝的Meta分析

目的系统评价前入路平片（Lichtenstein）无张力疝修补术与网塞充填式（Mesh-plug）无张力疝修补术在腹股沟疝治疗中的应用效果。 方法制订纳入和排除标准,检索数据库中发表时间在2000年1月至2019年6月的文献,并结合所查找文献中的参考文献,选择有关Lichtenstein疝修补与Mesh-plug疝修补治疗原发性腹股沟疝的临床随机对照研究,由2位作者分别进行质量评估并提取数据资料,结局指标包括手术时间、术后复发、补片费用、血肿与血清肿、腹股沟区不适感、疼痛及感染情况,将最终纳入的文献数据整理后进行Meta分析。 结果共有10篇RCT研究纳入分析,Lichtenstein组1472例,Mesh-plug组1457例。Meta分析结果显示：与Mesh-plug疝修补术相比,Lichtenstein疝修补术后血肿、血清肿发生率更低[RR=1.45,95% CI（1.02,2.06）,P=0.04],手术费用更少[WMD=155.15,95% CI（112.78,197.53）,P<0.000 01],但手术时间稍长[WMD=－7.51,95% CI（－11.33,－3.68）,P=0.0001]。而两者术后腹股沟区不适感、感染、复发、早期疼痛评分以及慢性疼痛的发生率无明显差异。 结论与Mesh-plug疝修补术相比,Lichtenstein疝修补术在降低术后血清肿、血肿发生率以及手术费用方面有一定优势,但手术时间稍长,建议在临床上Lichtenstein疝修补术优先Mesh-plug疝修补术使用。     

Preperitoneal repair for recurrent inguinal hernia: Laparoscopic and open approach

Background: The aim of this study was to investigate the outcome of preperitoneal repair using laparoscopic (TEP) and open (OPM) approach in recurrent inguinal hernia. Methods: We performed a prospective controlled nonrandomized clinical study in 188 patients with 207 recurrent inguinal hernias over a period of 5 years. TEP repair was employed for 86 repairs, and OPM was used in 121 procedures. The main outcome measurements were: recurrence rate, operating time, hospital stay, and postoperative complications. Results: There were three recurrences (1.7%). Two in the OPM group (1.8%) and one (1.3%) in the TEP group [P=NS (not significant)]. The TEP procedure was faster than OPM for unilateral repair (40.8 vs 46.3 min) (P<0.001). Postoperative complications were more frequent in the OPM group (23.9%) than the TEP group (13.9%) (P=NS). Hospital stay was significantly shorter in the TEP group (1.2 vs 3.9 days) (P<0.001). Conclusions: Preperitoneal approach (open or laparoscopic) seems to be a good option in recurrent inguinal hernia when these procedures are done by experienced surgeons.

Postoperative convalescence after inguinal hernia surgery: Prospective randomized multicenter study of laparoscopic versus Shouldice inguinal hernia repair in 1042 patients

Interest in inguinal hernia surgery has increased significantly with the introduction of new operating techniques during the past decade. This multicenter study compared short-term results in patients treated by the laparoscopic transabdominal preperitoneal patch technique (TAPP; n=518) and the Shouldice technique (n=524). We evaluated demographics, operative data, complications, hospital stay, postoperative pain, use of analgesics, functional status, sick leave, and complaints up to 3 months postoperatively. The median operating time was shorter in the Shouldice group (55 vs. 65 min), but there were no significant differences in complication rates, and major complications were rare. The hospital stay was 1 day or less in over 98% of cases in both groups, but more operations were performed on outpatient basis in the Shouldice group. In the TAPP group postoperative pain and analgesic consumption were less, postoperative functional status was better, and sick leave was shorter (10 vs. 14 days). These results show that the two methods are equally safe and have few major complications. The TAPP operation is associated with less postoperative pain, better postoperative functional status, and shorter sick leave, but at the price of a longer operating time.

腹腔镜经腹腹膜前疝修补术与Lichtenstein术在成人腹股沟嵌顿疝的疗效

目的探讨腹腔镜经腹腹膜前疝修补术（TAPP）与Lichtenstein术在成人腹股沟嵌顿疝治疗中的临床应用比较。 方法回顾分析2014年1月至2019年1月,上海中医药大学附属普陀医院急诊收治并完成无张力疝修补手术病例共82例成人腹股沟嵌顿疝患者临床资料,根据手术方式不同分为2组。观察组38例,行TAPP术;对照组44例,行Lichtenstein术。将2组手术时间,术后住院时间,术后疼痛评分,术后血清肿,术后其他并发症（复发、术后感染、术后肠坏死、出血）,术后总费用等进行统计学分析。 结果2组在术后血清肿及其他并发症上比较,差异无统计学意义（P>0.05）;研究组手术时间及住院费用明显高于对照组,差异有统计学意义（P<0.05）;研究组术后住院时间及术后疼痛评分低于对照组,差异有统计学意义（P<0.05）。 结论TAPP术较Lichtenstein术手术时间长,术后总费用相对高,但其具有创伤小、疼痛轻、恢复快、复发率低等特点。
