Background
Chronic pain after prosthetic inguinal hernioplasty is one of the most important current issues in the current literature debate. Mechanisms related to pain development are only partially known. Influence of age as well as other factors is still unclear. The aim of this work was to evaluate whether development of chronic pain after open prosthetic plug and mesh inguinal hernioplasty is influenced by age.Methods
Analysis was retrospectively conducted, dividing our cohort of patients (2,902) who had undergone prosthetic open plug&mesh inguinal hernioplasty from Jannuary 1994 to May 2012, following only the age criterion (cut-off 65 yrs.), into two groups (Gr.A<65 yrs, Gr.B>65 yrs.). All patients were routinely submitted to a postoperative questionnaire. Complications such as analgesic assumption were registered in both groups. Pain intensity was classified following the Visual Analogic Scale (VAS). Incidence of chronic pain, discomfort, and numbness, was assessed in both groups. Statistical significance was assessed by X2-test.Results
Only 0.2% of patients suffered from a recurrence in our cohort. Postoperative chronic pain was observed in Gr. A in 0.12% of patients vs Gr.B 0.09% (p>0.05). Incidence of other postoperative symptoms such as discomfort or numbness were slightly prevalent on young patients (respectively p = 0.0286 and p = 0.01), while for hyperesthesia and sensation of foreign body no statistically significant difference of incidence between groups was observed.Conclusions
Real chronic pain after inguinal hernioplasty is a rare clinical entity. Other causes of chronic pain should be accurately researched and excluded. In young patients psychological factors seem to show a slight influence. There was no influence of age on chronic postoperative pain incidence after inguinal hernioplasty.2.
Purpose
To evaluate the efficacy and safety of laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair in patients who have undergone robot-assisted laparoscopic radical prostatectomy (RALP).Methods
From July 2014 to December 2016, TAPP inguinal hernia repair was conducted in 40 consecutive patients who had previously undergone RALP. Their data were retrospectively analyzed as an uncontrolled case series.Results
The mean operation time in patients who had previously undergone RALP was 99.5 ± 38.0 min. The intraoperative blood loss volume was small, and the duration of hospitalization was 2.0 ± 0.5 days. No intraoperative complications or major postoperative complications occurred. During the average 11.2-month follow-up period, no patients who had previously undergone prostatectomy developed recurrence.Conclusions
Laparoscopic TAPP inguinal hernia repair after RALP was safe and effective. TAPP inguinal hernia repair may be a valuable alternative to open hernioplasty.3.

Background
To analyse the prevalences of the cam and pincer morphologies in a cohort of patients with groin pain syndrome caused by inguinal pathologies.Materials and methods
Forty-four patients (40 men and 4 women) who suffered from groin pain syndrome were enrolled in the study. All the patients were radiographically and clinically evaluated following a standardised protocol established by the First Groin Pain Syndrome Italian Consensus Conference on Terminology, Clinical Evaluation and Imaging Assessment in Groin Pain in Athlete. Subsequently, all of the subjects underwent a laparoscopic repair of the posterior inguinal wall.Results
The study demonstrated an association between the cam morphology and inguinal pathologies in 88.6% of the cases (39 subjects). This relationship may be explained by noting that the cam morphology leads to biomechanical stress at the posterior inguinal wall level.Conclusions
Athletic subjects who present the cam morphology may be considered a population at risk of developing inguinal pathologies.Level of evidence

Introduction
A multimodal pain treatment including local anesthetics is advised for perioperative analgesia in bariatric surgery. Due to obesity, bariatric surgery patients are at risk of respiratory complications. Opioid consumption is an important risk factor for hypoventilation. Furthermore, acute postoperative pain is an important risk factor for chronic postsurgical pain. In this study, we aimed to evaluate whether preperitoneal anesthesia with bupivacaine would reduce pain and opioid consumption after bariatric surgery.Methods
One hundred adults undergoing laparoscopic bariatric surgery were randomized to receive either preperitoneal bupivacaine 0.5% or normal saline before incision. Postoperative opioid consumption, postoperative pain, and postoperative recovery parameters were assessed for the first 24 h after surgery. One year after surgery, chronic postsurgical pain and influence of pain on daily living were evaluated.Results
Postoperative opioid consumption during the first hour after surgery was 2.8?±?3.0 mg in the bupivacaine group, whereas in the control group, it was 4.4?±?3.4 mg (p =?0.01). Pain scores were significantly reduced in this first hour at rest and at 6 h during mobilization on the ward. One year after surgery, the incidence of chronic postsurgical pain was 13% in the bupivacaine group versus 40% in the placebo group.Conclusion
This study shows that preperitoneal local anesthesia with bupivacaine results in a reduction in opioid consumption and postoperative pain and seems to lower the incidence rate of chronic postsurgical pain after laparoscopic bariatric surgery.5.
Background
Lichtenstein hernioplasty has relatively low recurrence rate, but chronic inguinal pain may cause harm to the patient. The aim of our study was to compare long-term results of cyanoacrylate glue versus absorbable sutures for mesh fixation in Lichtenstein hernioplasty.Methods
Lichtenstein hernioplasty (n = 302) was performed under local anesthesia in three hospitals. The patients were randomized to receive either 1 ml of butyl-2-cyanoacrylate tissue glue (Glubran®; 151 hernias) or absorbable polyglycolic acid sutures (Dexon®; 151 hernias) for mesh fixation (Optilene® mesh). Short-term results were published previously. Chronic groin pain, foreign body sensation, use of analgesics, recurrence and re-operations were analyzed 7 years after surgery.Results
We reached 236 patients (78%) to present study. In the glue group (n = 115), there were five (4.3%) and in the suture group (n = 121) three (2.5%) recurrent hernias (p = 0.491). The prevalence of chronic pain (NRS ≥ 3) in the patients without re-operations was similar in two groups: 15/118 (13%) and 13/111 (12%), respectively (p = 0.843). There were no significant differences in the foreign body sensation (8/14, p = 0.267) or in the need of analgesics (2/2, p = 1.00) between the two study groups.Conclusion
Both cyanoacrylate glue and mesh fixation with absorbable sutures were equal in terms of chronic pain and rate of recurrences in Lichtenstein hernioplasty after 7-year follow-up.Trial registration number

Background
The indications for sleeve gastrectomy as a primary procedure for the surgical treatment of morbid obesity have increased worldwide. Pain is the most common complaint for patients on the first day after laparoscopic sleeve gastrectomy. There are various methods for decreasing pain after laparoscopic sleeve gastrectomy such as the use of intraperitoneal bupivacaine hydrochloride. This clinical trial was an attempt to discover the effects of intraperitoneal bupivacaine hydrochloride on alleviating postoperative pain after laparoscopic sleeve gastrectomy.Methods
In general, 120 patients meeting the inclusion criteria were enrolled. Patients were randomly allocated into two interventions and control groups using a balanced block randomization technique. One group received intraperitoneal bupivacaine hydrochloride (30 cm3), and the other group served as the control one and did not receive bupivacaine hydrochloride. Diclofenac suppository and paracetamol injection were administered to both groups for postoperative pain management.Results
The mean subjective postoperative pain score was significantly decreased in patients who received intraperitoneal bupivacaine hydrochloride within the first 24 h after the surgery; thus, the instillation of bupivacaine hydrochloride was beneficial in managing postoperative pain.Conclusions
The intraoperative peritoneal irrigation of bupivacaine hydrochloride (30 cm3, 0.25%) in sleeve gastrectomy patients was safe and effective in reducing postoperative pain, nausea, and vomiting (IRCT2016120329181N4).7.

Purpose
Laparoscopic inguinal hernia repair has facilitated early mobilization. Management of post-operative pain is paramount in these day case procedures. The aim of this study was to compare laparoscopic-assisted transversus abdominis plane (TAP) block with periportal local anaesthetic infiltration in managing post-operative pain.Methods
A double-blind, randomized controlled trial was conducted with patients undergoing elective laparoscopic inguinal hernia repair (January 2016–October 2017). The intervention group received laparoscopic-assisted TAP block with 30 ml 0.25% Bupivacaine. The control group received 15ml of 0.5% Bupivacaine at the periportal sites. Primary outcome measure was assessment of post-operative pain scores using numerical rating on visual analogue scale (VAS) at rest and on coughing at 3 h. Efficacy of TAP block was assessed as reduction in mean pain scores in the order of 2 points using the VAS.Results
60 (57 males and 3 females) were enrolled; 30 patients were randomized to each group. Patient demographics, anaesthetic and surgical times were similar in both groups. Mean pain scores were significantly reduced in the intervention group at 3 (3.1 vs 1.1 p?<?0.001) and 6 h (4.1 vs 1.7 p?<?0.001) at rest and on coughing at 3 (4.8 vs 2.1 p?<?0.001) and 6 h (5.4 vs 3.0 p?<?0.001). Patient satisfaction was higher (8.0 vs 6.8 p?<?0.001) and rescue analgesic requirements (169.4vs 71.3 p?<?0.001) lower in the intervention group.Conclusions
This analysis has demonstrated the therapeutic benefit of laparoscopic-assisted TAP block in initial post-operative pain management for patients undergoing elective laparoscopic inguinal hernia repair.8.

Purpose
In Japan, inguinal hernia repair is widely performed with local anesthesia. The objective of this study was to evaluate safety and efficacy of intravenous dexmedetomidine as a sedation agent with local anesthesia in inguinal hernia repair.Methods
We performed this randomized, single-blind study for 200 patients who were scheduled to undergo inguinal hernia repair with local anesthesia. Patients were randomly divided into two groups (dexmedetomidine group: Group D, midazolam group: Group M). The primary outcome was to evaluate the safety of intravenous dexmedetomidine. Secondary outcomes were to analyze results of operators’ surveys and patients’ questionnaires and evaluate implementation of conscious sedation.Results
Incidence of respiratory depression was significantly higher in Group M than Group D (p = 0.03). Other adverse events examined did not differ significantly. All three operators’ questionnaires indicated that results were better in Group D than Group M. More than 70% of patients in both groups were satisfied with the surgery. More than 80% of Group D patients and 74% of Group M patients achieved a state of conscious sedation.Conclusion
This study demonstrated that intravenous dexmedetomidine during hernia repair with local anesthesia is safe and the results were satisfactory to both operators and patients.9.

Background
Opioid analgesics have been a standard modality for postoperative pain management after total knee arthroplasty (TKA) but are also associated with increased risk of nausea, pruritus, vomiting, respiratory depression, prolonged ileus, and cognitive dysfunction. There is still a need for a method of anesthesia that can deliver effective long-term postoperative pain relief without incurring the high cost and health burden of opioids and nerve blocks.Questions/purposes
(1) Is liposomal bupivacaine-based periarticular injection (PAI) more effective than morphine-based spinal anesthesia or ropivacaine-based PAI in controlling postoperative pain after TKA? (2) Do patients treated with liposomal bupivacaine-based PAI experience fewer opioid-related adverse events compared with patients treated with morphine-based spinal anesthesia or ropivacaine-based PAI in controlling postoperative pain after TKA?Methods
This multicenter, blind trial randomized 119 patients undergoing TKA with spinal anesthesia to receive spinal anesthesia plus periarticular injection with liposomal bupivacaine (40 patients), spinal anesthesia with bupivacaine plus intrathecal morphine (41 patients) but no liposomal bupivacaine injection, or spinal anesthesia with bupivacaine (38 patients) and no liposomal bupivacaine injection. The two groups that did not receive periarticular liposomal bupivacaine did receive periarticular injection with ropivacaine, and all three groups had ketorolac (30 mg) plus epinephrine (1:1000) in the periarticular injections. Patients in all three groups received identical perioperative multimodal analgesic and antiemetic drugs. All patients were analyzed in the group to which they were randomized and no patients were lost to followup. The primary study endpoints were visual analog score (VAS) for pain and narcotic use during postoperative day 1. Secondary endpoints included side effects associated with narcotic administration during the hospital stay.Results
Mean VAS pain in the liposomal bupivacaine PAI group was lower than that for the ropivacaine PAI group at 6 hours (1.8 ± 2.1 versus 3.3 ± 2.3, p = 0.005, mean difference: 1.5, 95% confidence interval [CI], 0.5–2.5) and 12 hours (1.5 ± 2.0 versus 3.3 ± 2.4, p < 0.001, mean difference: 1.8, 95% CI, 0.8–2.8) after surgery. The morphine spinal group had lower pain compared with the liposomal bupivacaine PAI group at 6 hours (0.9 ± 1.8 versus 1.8 ± 2.1, p = 0.035, mean difference: 1.0, 95% CI, 0.1–1.8), but there was no difference at 12 hours (0.8 ± 1.5 versus 1.5 ± 2.0, p = 0.086, mean difference: 0.7, 95% CI, ?0.1 to 1.5). The magnitude of the differences at 6 and 12 hours are near the lower end of minimal clinically important differences reported in the literature, and thus the improvement shown in this study may only represent a small clinical improvement. Both the liposomal bupivacaine group (13% [five of 40]) and the ropivacaine group (5% [two of 38]) had fewer incidents of itching (pruritus) than the spinal morphine group (38% [15 of 41]) (p = 0.001).Conclusions
This prospective multicenter three-arm blind randomized controlled trial showed potentially improved pain control at 6 and 12 hours in the liposomal bupivacaine and intrathecal morphine groups compared with the ropivacaine group at the cost of much higher incidences of pruritus (itching) in the intrathecal morphine group. Based on these results, we prefer the use of PAI with liposomal bupivacaine as an alternative to spinal anesthesia with intrathecal morphine as a result of similar postoperative pain control and the potential for reducing adverse events.Level of Evidence

Background
The aim of this study is to evaluate the feasibility and the safety of hernioplasty under local anaesthesia in elderly patients with significant comorbidity.Methods
A total of 218 patients underwent inguinal hernia repair with mesh between June 2009 and July 2012. Presence of comorbid conditions and complications were compared between patients younger and older than 70 years.Results
Hernia repair in older patients were more likely associated with comorbid conditions than in their younger counterparts ( hypertension: 25% vs 8.16%; cardiovascular diseases: 50% vs 22%; benign prostatic hypertrophy 60% vs 30%). The most common postoperative complications in both groups were recurrence, wound infection, urinary retention. There was a slightly higher rate of complication in elderly group.Conclusions
Inguinal hernia repair with local anaesthesia is quite safe and results in a good success rate in elderly patients despite a higher rate of comorbidity typical of this kind of patient.11.

Background
Chronic pain after inguinal hernioplasty is the foremost side-effect up to 10–30% of patients. Mesh fixation may influence on the incidence of chronic pain after open anterior mesh repairs.Methods
Some 625 patients who underwent open anterior mesh repairs were randomized to receive one of the three meshes and fixations: cyanoacrylate glue with low-weight polypropylene mesh (n?=?216), non-absorbable sutures with partially absorbable mesh (n?=?207) or self-gripping polyesther mesh (n?=?202). Factors related to chronic pain (visual analogue scores; VAS?≥?30, range 0–100) at 1 year postoperatively were analyzed using logistic regression method. A second analysis using telephone interview and patient records was performed 2 years after the index surgery.Results
At index operation, all patient characteristics were similar in the three study groups. After 1 year, chronic inguinal pain was found in 52 patients and after 2 years in only 16 patients with no difference between the study groups. During 2 years’ follow-up, three (0.48%) patients with recurrences and five (0.8%) patients with chronic pain were re-operated. Multivariate regression analysis indicated that only new recurrent hernias and high pain scores at day 7 were predictive factors for longstanding groin pain (p?=?0.001). Type of mesh or fixation, gender, pre-operative VAS, age, body mass index or duration of operation did not predict chronic pain.Conclusion
Only the presence of recurrent hernia and early severe pain after index operation seemed to predict longstanding inguinal pain.12.
Purpose
Laparoscopic transabdominal preperitoneal inguinal hernia repair (TAPP) is technically difficult and not infrequently followed by postoperative complications and pain, especially when performed by inexperienced surgeons. To simplify TAPP and reduce postoperative pain, we devised a novel procedure whereby TAPP is carried out after the inguinal preperitoneal infiltration of diluted lidocaine and epinephrine saline solution and carbon dioxide gas (tumescent TAPP). This report introduces the concept of tumescent TAPP and summarizes its operative results.Methods
About 120 ml of diluted lidocaine and epinephrine solution and 60 ml of CO2 gas were infiltrated into the inguinal preperitoneal space through a transabdominal needle before TAPP. Tumescent TAPP was performed for 400 patients (355 men, 45 women; mean age, 63.2 years).Results
Using tumescent TAPP, we found it easier to confirm the inguinal anatomy and dissect the preperitoneal layer and inguinal floor, with less bleeding. The mean operation time was 101.9 min and there were few perioperative complications and minimal pain.Conclusions
Tumescent TAPP makes conventional TAPP easier and safer; however, this procedure should be verified by a comparative study with conventional TAPP.13.
Background
Inguino-scrotal herniation of the ureter is a rare and difficult situation for a surgeon, especially if only recognized during inguinal hernia repair.Methods
An 83-year-old gentleman, with a previous history of radiation treatment for squamous anal cancer, presented with a large left inguinoscrotal hernia causing occasional pain at the base of the scrotum. Follow-up, post-radiation therapy CT scan showed a hernia sac containing the bladder and large bowel. Calcifications in the sac were interpreted as bladder stones, in keeping with the history of left renal calculi.Results
During hernia repair careful dissection revealed a herniated portion of the left ureter located alongside a large hernia sac, complicated by ureteral calculi. Following stones extraction and ureteral repair, hernia repair with mesh was successfully accomplished. Pathogenesis of ureteric herniation is reviewed.Conclusion
A herniated ureter is potentially a source of serious renal or ureteral complications. When discovered, ureteric hernias should be surgically repaired. If preoperative detection of a ureter herniation alongside an inguinal hernia is missed, awareness of the existence of this condition may help avoid iatrogenic ureteral damage injury during a complex hernioplasty. Documentation of unexplained, sizeable and distinct calcifications in an inguino-scrotal hernia sac, particularly in a patient with a history of urolithiasis, may suggest the presence of a herniated, calculus-filled ureter. In such cases, retrograde pyelograms may be considered for a definitive diagnosis prior to surgery.14.

Purpose
To demonstrate the benefit and safety of conservative therapy for round ligament varicosities (RLVs) that are easily misdiagnosed as inguinal hernias.Methods
We retrospectively analyzed clinical materials of 41 consecutive cases of RLVs diagnosed by ultrasound in a single hospital from January 2011 to December 2015. Misdiagnosis rate, clinical and sonographic features, management after diagnosis and prognosis were recorded.Results
All forty-one cases were pregnant females in their second or third trimester. Twenty-eight cases were first misdiagnosed as inguinal hernias (68.3%). Thirty cases presented as reducible swelling in the inguinal area (73.2%), and twenty-five of which were painful (61.0%). Four cases only felt pain in the inguinal area without swelling (9.7%). Seven cases had no obvious discomfort (17.1%). All cases were diagnosed as RLVs by gray-scale and color Doppler ultrasonography and justified a wait-and-see strategy. Thirty-seven cases were followed until total recovery after delivery (follow-up rate 90.2%). Swelling with or without pain disappeared spontaneously postpartum.Conclusions
RLVs are easily misdiagnosed as inguinal hernias and color Doppler of the inguinal area is the best examination for making the correct diagnosis. Conservative therapy for RLV is beneficial and safe when assured by color Doppler.15.

Objective
The aim of this study was to evaluate whether a relation exists between surgical expertise and incidence of chronic postoperative inguinal pain (CPIP) after inguinal hernia repair using the Lichtenstein procedure .Background
CPIP after inguinal hernia repair remains a major clinical problem despite many efforts to address this problem. Recently, case volume and specialisation have been found correlated to significant improvement of outcomes in other fields of surgery; to date these important factors have not been reviewed extensively enough in the context of inguinal hernia surgery.Methods
A systematic literature review was performed to identify randomised controlled trials reporting on the incidence of CPIP after the Lichtenstein procedure and including the expertise of the surgeon. Surgical expertise was subdivided into expert and non-expert.Results
In a total of 16 studies 3086 Lichtenstein procedures were included. In the expert group the incidence of CPIP varied between 6.9 and 11.7 % versus an incidence of 18.1 and 39.4 % in the non-expert group. Due to the heterogeneity between groups no statistical significance could be demonstrated.Conclusion
The results of this evaluation suggest that an association between surgical expertise and CPIP is highly likely warranting further analysis in a prospectively designed study.16.

Purpose
We hypothesized that cooling hyperbaric bupivacaine from 23 to 5 °C may limit the intrathecal spread of bupivacaine and therefore increase the success rate of unilateral spinal anesthesia and decrease the rate of hemodynamic complications.Methods
A hundred patients scheduled for elective unilateral inguinal hernia surgery were randomly allocated to receive 1.8 ml of 0.5 % hyperbaric bupivacaine intrathecally at either 5 °C (group I, n = 50) or at 23 °C (group II, n = 50). Following spinal block at the L2-3 interspace, the lateral decubitus position was maintained for 15 min. Unilateral spinal anesthesia was assessed and confirmed at 15 and 30 min. The levels of sensory and motor block on the operative side were evaluated until complete resolution.Results
The rate of unilateral spinal anesthesia at 15 and 30 min was significantly higher in group I (p = 0.015 and 0.028, respectively). Hypotensive events and bradycardia were significantly rarer in group I (p = 0.014 and 0.037, respectively). The density and viscosity of the solution at 5 °C was significantly higher than at 23 °C (p < 0.0001). Compared with group II, sensory block peaked later in group I (17.4 vs 12.6 min) and at a lower level (T9 vs T7), and two-segment regression of sensory block (76.4 vs 84.3 min) and motor block recovery was shorter (157.6 vs 193.4 min) (p < 0.0001).Conclusions
Cooling of hyperbaric bupivacaine to 5 °C increased the density and viscosity of the solution and the success rate of unilateral spinal anesthesia, and decreased the hemodynamic complication rate.17.
Purpose
Enlargement of the ilioinguinal nerve at the external inguinal ring is observed in 34% of patients undergoing primary open inguinal herniorrhaphy; in 88% of patients it occurs at the fascial edge where the hernia mushrooms with abdominal pressure. Compression neuropathy occurs near many anatomical nerve constriction sites and is associated with enlargement of the peripheral nerve accompanied by sensory changes.Methods
In this prospective study, Carolina Comfort Scale (CCS) questionnaire data was collected for 35 primary hernia repairs. Each patient underwent primary inguinal herniorrhaphy that included ilioinguinal neurectomy. All nerves were sampled proximal to the external inguinal ring. Any nerves with grossly increased overall diameter to any degree distal to the external ring were additionally sampled in the thickened portions. A neuropathologist performed histologic evaluation of the H&E-stained cross sections.Results
Paired comparison of proximal and distal nerves revealed a greater overall diameter and greater measured nerve-specific diameter in distal nerve segments. Nerves with increased overall diameter were also found to have a statistically significant positive correlation with four of eight pain measures. Additionally, increased nerve-specific diameter correlates with increased pain on four of eight pain values, but age effect on nerve diameter blunts this finding.Conclusions
Increased preoperative CCS pain values in primary open inguinal hernia are significantly correlated with gross enlargement of the overall diameter and nerve-specific diameter of the ilioinguinal nerve beyond the external inguinal ring. This is consistent with a compression neuropathy.18.
Purpose
To present a new and alternative method for surgical treatment of recurrent inguinal hernia after total extraperitoneal patch plastic (TEP).Methods
From January 2005 to September 2015, 35 patients (34 male, 1 female; mean age 65 ± 12.6 years) with recurrent inguinal hernia following TEP were operated at the Kliniken Essen-Mitte using a simplified method consisting of re-fixation of the primary mesh to the inguinal ligament by an anterior approach.Results
The mean operating time was 47 ± 22 min. All complications were minor with an overall incidence of 6%. After a mean follow-up of 54 months one re-recurrence was observed.Conclusions
This Simplified Hernia Repair is safe and avoids additional foreign body implantation. Therefore, it is our method of choice for recurrent inguinal hernias after TEP.19.
Introduction
The guidelines of the international hernia societies recommend laparo-endoscopic inguinal hernia repair for recurrent hernias after open primary repair. To date, no randomized trials have been conducted to compare the TEP vs TAPP outcome for recurrent inguinal hernia repair. A Swiss registry study identified only minor differences between the two techniques, thus suggesting the equivalence of the two procedures.Materials and Methods
Between September 1, 2009 and August 31, 2013 data were entered into the Herniamed Registry on a total of 2246 patients with recurrent inguinal hernia repair following previous open primary operation in either TAPP (n?=?1,464) or TEP technique (n?=?782).Results
Univariable and multivariable analysis did not find any significant difference between TEP and TAPP with regard to the intraoperative complications, complication-related reoperations, re-recurrences, pain at rest, pain on exertion, or chronic pain requiring treatment. The only difference identified was a significantly higher postoperative seroma rate after TAPP, which was influenced by the surgical technique, previous open primary operation and EHS-classification medial and responded to conservative treatment.Conclusion
TEP and TAPP are equivalent surgical techniques for recurrent inguinal hernia repair following previous open primary operation. The choice of technique should be tailored to the surgeon’s expertise.20.
