TEP for elective primary unilateral inguinal hernia repair in men: what do we know?

Laparoscopic Inguinal Hernia Repair in the Obese Patient Population: A Single-Center Five-Year Experience

Purpose The objective of the present study is to evaluate the distribution of the transabdominal preperitoneal (TAPP) and the totally extraperitoneal repair (TEP) procedures among the obese and non-obese patient populations, to show how obesity impacts daily practice by reviewing the experience of a single center, and finally, to assess the outcomes of the operations. Methods All patients who underwent elective, minimally invasive inguinal hernia repair in our hospital from January 2017 to January 2022 were included in the present study. The data that were analyzed were patient demographics, each individual patient's American Society of Anesthesiology (ASA) score, the minimally invasive technique (TAPP or TEP) utilized, the body mass index (BMI), and other comorbidities such as underlying diabetes, hypertension, and smoking status. Results A total of 109 patients were included in the present analysis, of which 81 (74.3%) underwent elective TEP repairs while 28 (25.7%) underwent elective TAPP repairs. Overall, 39 (35.7%) patients were included in the obesity subgroup with an average BMI of 35.4 ± 4.9, with a range from 30.1 to 52.7, and 70 (64.3%) were included in the non-obese subgroup, with an average BMI of 23.2 ± 3.3 and a range from 16.2 to 29.7. Conclusions The laparoscopic approach to the inguinal hernia repair in obese patients has similar outcomes as an open approach regarding the 30-day events, in the hands of experienced surgeons with the advantages of the laparoscopic approach vs. the open one.

Bilateral inguinal hernia repair by laparoscopic totally extraperitoneal (TEP) vs. laparoscopic transabdominal preperitoneal (TAPP)

BACKGROUND

The guidelines recommend laparoscopic repair for bilateral inguinal hernia. However, few studies compare the totally extraperitoneal (TEP) and transabdominal preperitoneal (TAPP) techniques in bilateral inguinal hernias. This study aimed to compare the outcomes of TEP and TAPP in bilateral inguinal hernia.

METHODS

We conducted a retrospective cohort study of patients operated on for bilateral inguinal hernia by TEP and TAPP repair from 2016 to 2020. Intraoperative complications, operative time, acute postoperative pain, hospital stay, postoperative complications, chronic inguinal pain, and recurrence were compared.

RESULTS

A total of 155 patients were included in the study. TEP was performed in 71 patients (46%) and TAPP in 84 patients (54%). The mean operative time was longer in the TAPP group than in the TEP group (107 min vs. 82 min, p < 0.001). The conversion rate to open surgery was higher in the TEP group than in the TAPP group (8.5% vs. 0%, p = 0.008). The mean hospital stay was longer in the TAPP group than in the TEP group (p < 0.001). We did not observe significant differences in the proportion of postoperative complications (p = 0.672), postoperative pain at 24 h (p = 0.851), chronic groin pain (p = 0.593), and recurrence (p = 0.471). We did not observe an association between the choice of surgical technique (TEP vs. TAPP) with conversion rate, operative time, hospital stay, postoperative complications, chronic inguinal pain, or hernia recurrence when performing a multivariable analysis adjusted for the male sex, age, BMI, ASA, recurrent hernia repair, surgeon, and hernia size > 3cm.

CONCLUSIONS

Bilateral inguinal hernia repair by TEP and TAP presented similar outcomes in our study.

[Inguinal hernia operations-Always outpatient?]

Inguinal hernia operations represent the most frequent operations overall with 300,000 interventions annually in Germany, Austria and Switzerland (DACH region). Despite the announced political willingness and the increasing pressure from the legislator to avoid costly inpatient treatment by carrying out as many outpatient operations as possible, outpatient treatment has so far played a subordinate role in the DACH region. The Boards of the specialist societies the German Hernia Society (DHG), the Surgical Working Group Hernia (CAH of the DHG), the Austrian Hernia Society (ÖHG) and the Swiss Working Group Hernia Surgery (SAHC) make inroads into this problem, describe the initial position and assess the current situation.

Utilization of laparoscopic and open inguinal hernia repair at a large hernia center in China: a single-center observational study

BACKGROUND

The utilization of laparoscopic and open inguinal hernia repair in China remains unclear. We aim to investigate the rates of laparoscopic and open inguinal hernia repairs and its associated factors at a large hernia center.

METHODS

Data were obtained from the front sheet of medical records of Beijing Chaoyang hospital. Adult inguinal hernia inpatients who underwent hernia repairs between 2013 and 2020 were included. We calculated the overall rates of laparoscopic and open inguinal hernia repairs and compared the rate of laparoscopic repairs between different sex, age groups, types, and sides of inguinal hernias. Multivariable logistic regression was used to examine factors associated with the rate of laparoscopic repairs.

RESULTS

14,481 inpatients with inguinal hernia were included. 91.78% were male, 75.43% were more than 50 years, 75.20% were unilateral inguinal hernia, and 64.57% were indirect inguinal hernia. Overall, 49.47% underwent laparoscopic repairs and 50.53% underwent open repairs. Women had lower rate of laparoscopic repair than men, especially in those with unilateral hernias. Bilateral and direct inguinal hernia had higher rates of laparoscopic repair than unilateral and indirect inguinal hernia. Multivariable logistic regression showed that inpatients who were women, > 70 years, pantaloon inguinal hernia, with obstruction, and more comorbidities were less likely to have laparoscopic repairs.

CONCLUSION

Around 50% of inguinal hernia patients at a large hernia center underwent laparoscopic repairs, which was more commonly performed in male, young, bilateral inguinal hernia, and inpatients without comorbidities. More efforts were needed to increase the safe and effective laparoscopic utilization among female patients with inguinal hernias.

Comparison of balloon dissection and telescopic dissection of the preperitoneal space in laparoscopic totally extraperitoneal hernia repair: a systematic review and meta-analysis

PURPOSE

Safety in creating a preperitoneal space is crucial in laparoscopic totally extraperitoneal (TEP) hernia repairs. In this systematic review and meta-analysis, we compared the outcomes of balloon dissection and telescopic dissection in patients with inguinal or femoral hernias who underwent TEP hernia repair.

METHODS

We searched PubMed, Embase, Web of Science, and Cochrane databases for randomized controlled trials (RCTs) and prospective and retrospective studies published from inception to July 2022. Meta-analysis was performed using a random-effects model. The treatment outcome was measured using operation time, incidence of intraoperative hemorrhage, peritoneal laceration, conversion to other approaches, surgical site infection (SSI), hematoma, seroma formation, hernia recurrence, and postoperative pain.

RESULTS

Five RCTs, one prospective study, and two retrospective studies (in total, 936 patients) were included. No significant between-group differences were noted in operation time, SSI, hematoma, seroma, recurrence rate, and postoperative pain on days 1 and 7. The conversion rate was significantly lower in the balloon group than in the telescopic group (odds ratio, 0.34; 95% confidence interval, 0.15-0.81).

CONCLUSIONS

Both balloon dissection and telescopic dissection are viable techniques for creating preperitoneal space in laparoscopic TEP hernia repair and have similar operation time, complication rate, and postoperative pain. Nevertheless, the conversion rate was lower in patients undergoing balloon dissection than in those undergoing telescopic dissection.

Prospective, randomized clinical trial of laparoscopic totally extraperitoneal inguinal hernia repair using conventional versus custom-made (mosquito) mesh performed in Cameroon: a short-term outcomes

BACKGROUND

Adverse economic conditions often prevent the widespread implementation of modern surgical techniques in third world countries such as in Sub-Sahara Africa.

AIM OF THE STUDY

To demonstrate that a modern technique (laparoscopic totally extraperitoneal inguinal hernioplasty [TEP]) can safely be performed at significantly lower cost using inexpensive mesh material.

SETTINGS

Douala University Hospital Gynecology, Obstetrics and Pediatrics and two affiliated centers, Ayos Regional Hospital and Edéa Regional Hospital in Cameroon.

PATIENTS AND METHODS

Prospective randomized controlled trial (RCT) of consecutive adult patients presenting with primary inguinal hernia treated by TEP, comparing implantation of sterilized mosquito mesh (MM) with conventional polypropylene mesh (CM). Primary endpoints were peroperative, early and midterm postoperative complications and hernia recurrence at 30 months.

RESULTS

Sixty-two patients (48 males) were randomized to MM (n = 32) or CM (n = 30). Groups were similar in age distribution and occupational features. Peroperative and early outcomes differed in terms of conversion rate (2/32 MM) due to external (electrical power supply) factors and mesh removal for early obstruction (1/30 CM). No outcome differences, including no recurrences, were noted after a median follow-up of 21 months.

CONCLUSION

In this RCT with medium-term follow-up, TEP performed with MM appears not inferior to CM.

Pediatric Groin Surgeries: A Comparison of Analgesic Effects of Caudal Block and Inguinal Field Block Using Plain Bupivacaine

INTRODUCTION

There is a paucity of studies in the West African sub-region which have compared both the intraoperative and postoperative analgesic effects of caudal block and inguinal field block using plain bupivacaine in groin surgeries in children. The study aimed to compare the duration of analgesia and complications of caudal block and inguinal field block in pediatric groin surgeries.

PATIENTS AND METHODS

This was a prospective, double-blind randomized study conducted at a tertiary health institution in North Central, Nigeria, over a period of 6 months. A total of 74 children scheduled for day case groin surgeries for inguinal hernia, hydrocoele and palpable undescended testis were recruited into the study. The effectiveness of the analgesic effect was assessed by measuring serum cortisol levels before surgery (i.e. baseline at 8am), 5minutes after caudal block or inguinal field block, and 1-hour after surgery. Post-operative pain was determined using FLACC score (Face, Legs, Activity, Crying and Consolability) every 15 minutes till 6 hours after surgery when the patients were discharged home and the caregivers measured the patients' pain scores using the FLACC score every 1 hour to a maximum duration of 10 hours after surgery. Data obtained from the study was entered into the study proforma and analysed using IBM SPSS version 21.0. The P value was considered statistically significant at <0.05.

RESULTS

A total of 74 patients were recruited for this study, with 68 males (91.9%) and 6 females (8.1%). The children's age range was 6 months to 7 years, with a mean age of 3.35 ± 1.90 years. The mean basal serum cortisol levels of the caudal block group and inguinal block group were 11.15 ± 5.38 µg/dL and 10.79 ± 4.92µg/d respectively (p-value = 0.767). Five minutes after caudal block, the mean serum cortisol level was 10.50 ± 5.39µg/dL while inguinal field block was 10.63 ± 4.68µg/dL (p-value = 0.288). The mean serum cortisol level obtained one hour after each procedure was 9.34 ± 4.05 µg/dL for the caudal block group and 10.00 ± 3.56 µg/dL in the inguinal field block group with p-value = 0.275.Using the FLACC score, the mean duration of analgesia in caudal block group was 372.00 ± 71.55 minutes and was inguinal field block group was 387.43 ± 62.65 minutes with a p-value = 0.116. There was no anaesthetic technique related complications that was recorded in both caudal block group and inguinal group during the study period.

CONCLUSION

This study demonstrated that caudal block and inguinal field block using plain bupivacaine provided comparable duration of analgesia in paediatric groin surgeries. Therefore, caudal block or inguinal field block using plain bupivacaine should be recommended for both intraoperative and postoperative analgesia in elective paediatric groin surgeries.

ARE THERE DIFFERENCES IN CHRONIC PAIN AFTER LAPAROSCOPIC INGUINAL HERNIA REPAIR USING THE TRANSABDOMINAL TECHNIQUE COMPARING WITH FIXATION OF THE MESH WITH STAPLES, WITH GLUE OR WITHOUT FIXATION? A CLINICAL RANDOMIZED, DOUBLE-BLIND TRIAL

ABSTRACT BACKGROUND: Regarding postoperative pain, it remains unclear whether non-fixation of the polypropylene prosthesis in transabdominal preperitoneal inguinal hernia repair produces the same outcomes as mesh fixation with glue or tackers. In addition, hernia recurrence is another aspect to be assessed in the comparison between non-fixation and mesh-fixation techniques (tackers and glue). AIMS: This study aimed to evaluate the incidence, quality of pain, and recurrence in patients undergoing laparoscopic inguinal hernioplasty (transabdominal preperitoneal) technique, comparing the fixation of the mesh with tackers versus with glue versus without fixation. METHODS: This is a prospective, double-blind study in which 63 patients presenting with primary unilateral inguinal hernia underwent laparoscopic transabdominal preperitoneal inguinal hernia repair and were randomized into three groups: no mesh fixation (n=21), mesh tacked (n=21), and mesh fixed with fibrin glue (n=21). Patients also responded to questionnaires in order to assess pain and pain quality and were followed up for 2 years. RESULTS: Neither mesh-fixation nor non-fixation techniques were found to affect postoperative chronic pain (p=0.535), but patients undergoing tacker fixation reported more pain descriptors (p=0.0021) and a higher pain index (p=0.002) on the McGill scale in the first 15 postoperative days (T0 and T1). No hernia recurrences were observed. CONCLUSIONS: Both mesh-fixation techniques (tackers and glue) used with the transabdominal preperitoneal approach did not influence the onset of inguinodynia, but tacker fixation was more likely to increase patient sensitivity to pain. Mesh placement without fixation produced the same pain and recurrence outcomes as mesh-fixation techniques. Also, no recurrence was observed in patients without mesh fixation in this study. Consequently, it has become an alternative therapy deserving consideration for hernia repair.

Long-Term Follow-Up of Lichtenstein Repair of Inguinal Hernia in the Morbid Patients With Self-Gripping Mesh (ProgripTM)

Objective: This study aimed to demonstrate the safety and the efficacy of the self-gripping mesh (Progrip^TM) for inguinal hernia repair in morbid patients of the higher American Society of Anesthesiologists (ASA) classification (ASA III and IV). The incidence of chronic pain, postoperative complications, and hernia recurrence was evaluated.

Methods: Data were collected retrospectively from the files of the patient and were analyzed for 198 hernias in 147 patients. All the patients included in this study had undergone inguinal hernia repair by Lichtenstein approach with the self-gripping mesh (Progrip^TM) in the same clinical center. Preoperative, perioperative, and postoperative data were collected and a long-term follow-up of 31.8 ± 19.5 m (5–60 m) was performed. Complications, pain scored on a 0–10 numeric rating scale (NRS), and hernia recurrence were assessed.

Results: During the past 5 years, 198 hernias in 147 patients were repaired with the Lichtenstein procedure with the self-gripping mesh (Progrip^TM). The majority of the patients were high level of the ASA classification (ASA III and IV) (95.9%), with ASA III (10.2%) and IV (85.7%). The mean operation time was 71.2 ± 23.8 min. The mean length of postoperative stay was 2.5 ± 2.1 days. There were no intraoperative complications. About 14 cases (7.1%) suffered from postoperative surgical wound complications, which were limited to the skin and subcutaneous tissue and were cured with the conservative methods successfully; there was no mesh infection, the acute postoperative pain was low or mild [visual analog scale (VAS) score ≤ 4] and the chronic postoperative pain was reported in three patients (1.5%) and tolerable, hernia recurrence (femoral hernia recurrence) occurred in one patient half a year after during the follow-up period.

Conclusion: This study demonstrated the advantages of the self-gripping mesh in hernia repair of the high-risk patients with inguinal hernia (ASA III and IV) by Lichtenstein procedure under local anesthesia.

Total extraperitoneal (TEP) versus laparoscopic transabdominal preperitoneal (TAPP) hernioplasty: systematic review and trial sequential analysis of randomized controlled trials

Purpose

To examine the updated evidence on safety, effectiveness, and outcomes of the totally extraperitoneal (TEP) versus the laparoscopic transabdominal preperitoneal (TAPP) repair and to explore the timely tendency variations favoring one treatment over another.

Methods

Systematic review and trial sequential analysis (TSA) of randomized controlled trials (RCTs). MEDLINE, Scopus, Web of Science, Cochrane Central Library, and ClinicalTrials.gov were consulted. Risk Ratio (RR), weighted mean difference (WMD), and 95% confidence intervals (CI) were used as pooled effect size measures.

Results

Fifteen RCTs were included (1359 patients). Of these, 702 (51.6%) underwent TAPP and 657 (48.4%) TEP repair. The age of the patients ranged from 18 to 92 years and 87.9% were males. The estimated pooled RR for hernia recurrence (RR = 0.83; 95% CI 0.35–1.96) and chronic pain (RR = 1.51; 95% CI 0.54–4.22) were similar for TEP vs. TAPP. The TSA shows a cumulative z-curve without crossing the monitoring boundaries line (Z = 1.96), thus supporting true negative results while the information size was calculated as adequate for both outcomes. No significant differences were found in term of early postoperative pain, operative time, wound-related complications, hospital length of stay, return to work/daily activities, and costs.

Conclusions

TEP and TAPP repair seems comparable in terms of postoperative hernia recurrence and chronic pain. The cumulative evidence and information size are sufficient to provide a conclusive evidence on recurrence and chronic pain. Similar trials or meta-analyses seem unlikely to show diverse results and should be discouraged.

Treatment of Inguinal Hernia: Systematic Review and Updated Network Meta-Analysis of Randomized Controlled Trials

BACKGROUND

Despite the advent of innovative surgical platforms and operative techniques, a definitive indication of the best surgical option for the treatment of unilateral primary inguinal hernia remains unsettled. Purpose was to perform an updated and comprehensive evaluation within the major approaches to inguinal hernia.

METHODS

Systematic review and network meta-analyses of Randomized Controlled Trials (RCTs) compare Lichtenstein tension-free repair, laparoscopic transabdominal preperitoneal (TAPP) repair, and totally extraperitoneal repair (TEP). Risk Ratio (RR) and weighted mean difference (WMD) were used as pooled effect size measures while 95% Credible Intervals (CrI) were used to assess relative inference.

RESULTS

Thirty-five RCTs (7,777 patients) were included. Overall, 3,496 (44.9%) underwent Lichtenstein, 1,269 (16.3%) TAPP, and 3,012 (38.8%) TEP repair. The Visual Analogue Scale (VAS) was significantly lower for minimally invasive repair at <12-hour, 24 hours, and 48 hours. Postoperative chronic pain [TAPP vs. Lichtenstein (RR = 0.36; 95% CrI 0.15-0.81) and TEP vs. Lichtenstein (RR = 0.36; 95% CrI 0.21-0.54)] and return to work/activities [TAPP vs. Lichtenstein (WMD = -3.3; 95% CrI -4.9; -1.8) and TEP vs. Lichtenstein (WMD = -3.6; 95% CrI -4.9; -2.4)] were significantly reduced for minimally invasive approaches. Wound hematoma and infection were significantly reduced for minimally invasive approaches while no differences were found for seroma, hernia recurrence, and hospital length of stay.

CONCLUSIONS

Minimally invasive TAPP and TEP repair seem associated with significantly reduced early postoperative pain, return to work/activities, chronic pain, hematoma, and wound infection compared to the Lichtenstein tension-free repair. Hernia recurrence, seroma, and hospital length of stay seem similar across treatments.

Transrectus sheath pre-peritoneal (TREPP) procedure versus totally extraperitoneal (TEP) procedure and Lichtenstein technique: a propensity-score-matched analysis in Dutch high-volume regional hospitals

Purpose

Results of the most commonly used inguinal hernia repair techniques often originate from expert centers or from randomized controlled studies. In this study, we portray daily-practice results of a high-volume, regional surgical group in the Netherlands, comparing TREPP (open (posterior) transrectus sheath pre-peritoneal) with Lichtenstein (open anterior) and TEP (endoscopic (posterior) totally extraperitoneal). We hypothesize that the TREPP shows more favorable outcome compared to the current gold standard procedures: TEP and Lichtenstein.

Methods

Between January 2016 and December 2018, 3285 consecutive patients underwent surgical treatment and were included for analysis. The outcome measures were postoperative pain, recurrence rate and other surgical complications. Propensity-score matching was used to address potential selection bias.

Results

After propensity-score matching, there was no statistically significant difference in postoperative pain in the TREPP group compared to the Lichtenstein group (TREPP 7.3% versus Lichtenstein 6.3%; p = 0.67) nor in TREPP compared to TEP (TREPP 7.4% versus TEP 4.1%; p = 0.064). There was no statistically significant difference in recurrences in the TREPP group compared to Lichtenstein (3.8% vs 2.5%; p = 0.42), nor in the TREPP versus TEP comparison (3.9% vs 2.8%; p = 0.55)

Conclusion

This study compares TREPP with Lichtenstein and TEP in the presence of postoperative pain, recurrences and other adverse outcomes. After propensity-score matching, no statistically significant difference in postoperative pain or recurrences remained between either TREPP compared to Lichtenstein, or TREPP compared to TEP. Based on these results, TREPP, Lichtenstein and TEP showed comparable results in postoperative pain, recurrences and other surgical site complications.

Modified port positions for totally extraperitoneal (TEP) repair for groin hernias: our experience

BACKGROUND

Totally extraperitoneal repair (TEP) is the preferred method of inguinal hernia repair for many surgeons worldwide. However, because of limited working space, there may be difficulties when operating on large and irreducible groin hernias and short stature patients. There are many ways in which the port positions can be modified during TEP for different kinds of hernias and according to the comfort of the surgeons.

METHODS

This is a retrospective analysis of prospectively collected data. We describe two different variations in port placement for TEP in patients with large irreducible hernias and short stature patients.

RESULTS

A total of 19 procedures were performed with these port positions. Most of these were large irreducible hernias or patients with short stature. With these modified port positions, difficult hernias could be completed with extraperitoneal approach. We had no recurrence and 5 seromas that eventually settled in 1-3 months.

CONCLUSION

Modified port positions in TEP by shifting the ports farther away can be useful for hernias where the surgery is difficult due to limited working space and is a good alternative to TAPP.

Patient-Reported Outcomes and Long-Term Results of a Randomized Controlled Trial Comparing Single-Port Versus Conventional Laparoscopic Inguinal Hernia Repair

BACKGROUND

Surgical techniques for inguinal hernia repair have evolved rapidly from open methods to conventional laparoscopic totally extra-peritoneal (CTEP) and recently single-port TEP (STEP). As there is currently no randomized controlled trial (RCT) reporting long-term patient-reported outcomes between CTEP and STEP, we reviewed patients who were randomized to CTEP or STEP 5 years after surgery.

METHODS

Telephone interviews were administered to patients with primary unilateral inguinal hernia recruited for the RCT comparing CTEP and STEP in 2011. The modified Body Image Questionnaire was used to measure long-term patient-reported outcomes.

RESULTS

Forty-two out of forty-nine of the STEP group and forty-one out of fifty of the CTEP group responded to phone interviews. Median follow-up time, demographic data and clinical outcomes were comparable between both groups. The Body Image Score (5-20: 5-least dissatisfied, 20-most dissatisfied; BIS score ± SD, STEP vs. CTEP, 5.33 ± 0.90 vs. 7.17 ± 1.87, p < 0.001) and Cosmetic Score (2-20: 2-least satisfied, 20-most satisfied; CS score ± SD, STEP vs. CTEP, 19.05 ± 1.31 vs. 15.87 ± 1.57, p < 0.001) were superior in the STEP group. Similarly, self-reported scar perception (1-cannot be seen, 2-can barely be seen, 3-visible; scar perception score ± SD, STEP vs. CTEP, 1.29 ± 0.51 vs. 2.55 ± 0.64, p < 0.001) and overall experience score (1-least satisfied, 10-most satisfied; overall satisfaction score ± SD, STEP vs. CTEP, 9.57 ± 0.67 vs. 8.22 ± 0.94, p < 0.001) were superior in the STEP group.

CONCLUSION

Patients who underwent STEP reported superior cosmetic and satisfaction scores and comparable surgical outcomes 5 years after surgery compared to the CTEP group. STEP should be strongly considered in patients who are concerned about long-term cosmetic outcomes and should be offered if surgical expertise is available. Trial registration NCT02302937.

Results at 3-year follow-up of totally extraperitoneal (TEP) hernia surgery with long-term resorbable mesh

INTRODUCTION

Synthetic non-resorbable mesh is almost standard in hernia surgery. However, several studies have showed negative effects of permanent implants such as chronic inflammation and complications involving different organs bordering the mesh. Such complications can raise the risk of chronic post-operative pain (CPP). Recently promising results regarding CPP have been published in patients with Lateral Inguinal Hernia (LIH) using a slowly resorbable mesh in Lichtenstein technique. For this reason the aim of the present study was to find the effect of a slowly resorbable implant on the long-term rate of hernia recurrence and chronic post-operative pain in patients with LIH repaired with TEP procedure.

METHODS

Prospective pilot study of TEP repair using TIGR^® Matrix Surgical Mesh in 35 primary LIH. At 3-year follow-up the Visual Analogue Scale (VAS) and the Inguinal Pain Questionnaire were employed to assess pain. Recurrence was determined by ultrasound and clinical examination.

RESULTS

All patients completed the pain questionnaires but one patient did not attend the planned clinical examination for the 3-year follow-up. No patients had CPP, as defined in the World Guidelines for Groin Hernia Management. Almost all patients had lower VAS score in any activity 3 years following surgery in comparison to the preoperative period. Three patients (8.8%) suffered symptomatic recurrence during the 3-year follow-up.

CONCLUSION

TEP repair in patients with LIH using a synthetic long-term resorbable mesh was found to be encouraging respecting chronic post-operative pain at 3-year follow-up but at the cost of an increased risk of recurrence.
