Total Extraperitoneal Inguinal Hernia Repair Research Articles

Telescopic dissection versus balloon dissection during laparoscopic totally extraperitoneal inguinal hernia repair: A prospective randomised control trial.

Totally extraperitoneal (TEP) repair involves creating a preperitoneal space. The preperitoneal space can be created by balloon or telescopic dissection (TD). Nevertheless, these techniques may have some complications. However, there are very few studies that compare these two techniques. This study aims to assess the impact and comprehensively compare the TD and balloon dissection (BD) methods in patients undergoing laparoscopic TEP inguinal hernia repair. This was a single-centre, double-blinded, prospective, randomised, controlled trial comparing BD and TD for the creation of the preperitoneal space. The primary end point was to compare the post-operative pain score, intraoperative complications and surgical site occurrence between the two groups. The secondary end point was to assess the impact of the dissection technique on operative time for the creation of extraperitoneal space during laparoscopic TEP inguinal hernia repair. A total of 46 patients were included in the study (23 in each group). Baseline parameters were comparable between the groups. The total operative time between the groups (120 min vs. 160 min; P < 0.005) was statistically significant. The incidence of the peritoneal breach was statistically less in the BD group (43% vs. 13%; P < 0.005). Other short-term and long-term complications were less in the BD group but not statistically significant. BD in TEP inguinal hernia repair reduces the operative time and peritoneal breach. When compared to TD in terms of operative time, routine use of BD can be proposed. It will be beneficial in the early part of the learning curve.

Quality of life following laparoscopic totally extraperitoneal repair of a unilateral reducible inguinal hernia.

Laparoscopic totally extraperitoneal (TEP) inguinal hernia repair has become increasingly favored over open Lichtenstein tension-free mesh repair owing to its associated benefits, including reduced postoperative pain, early return to normal activities, and a comparable recurrence rate. In recent years, emphasis has been placed on patient-reported outcomes, particularly health-related quality of life (QOL), as a critical metric for evaluating surgical success. This study aimed to evaluate the overall QOL following laparoscopic TEP repair of unilateral inguinal hernia. This prospective study enrolled patients aged 18 years or older who underwent elective laparoscopic TEP hernia repair for unilateral inguinal hernia from April 2020 to March 2022. Data collected include demographic details, hernia characteristics, postoperative complications, and postoperative QOL assessment. The Short Form 36 Health Survey Version 2 (SF-36v2), a validated general QoL questionnaire, was administered preoperatively and at 1 month, 6 months, and 1 year postoperatively. Statistical analysis utilized paired t-tests for comparisons, with significance set at a p-value <.05. A cohort of 49 patients, with a mean (standard deviation) age of 56.7 (14.0) years, predominantly comprising 47 men, was available for evaluation. Complications were observed in three (6.1%) of cases, with seroma/hematoma occurring in two patients and a wound infection necessitating antibiotic treatment in one patient. Notably, there were no instances of recurrence during the study period. Postoperative assessments revealed significant improvements in both physical and mental health at 1 month, with continued improvement noted up to 12 months. Laparoscopic TEP inguinal hernia repair has been shown to improve both physical and mental health in patients with unilateral reducible inguinal hernia, with the majority of the improvement typically occurring within the initial month following surgery. It is crucial to communicate these improvement trends to patients undergoing hernia repair to help manage their expectations effectively.

Laparoscopic totally extraperitoneal hernia repair in patients with a history of previous abdominopelvic surgery.

A retrospective cohort study of patients undergoing laparoscopic inguinal hernia repair compared short- and long-term outcomes between individuals with or without history of previous abdominopelvic surgery, aiming to determine the feasibility of totally extraperitoneal (TEP) repair within this population. All patients who underwent elective TEP inguinal hernia repair by one consultant surgeon across three London hospitals from January 2017 to May 2023 were retrospectively analysed to assess perioperative outcomes. Two hundred sixty-two patients were identified, of whom two hundred forty-three (93%) underwent laparoscopic TEP repair. The most frequent complications were haematoma (6.2%) and seroma (4.1%). Recurrence occurred in four cases (1.6% of operations, 1.1% of hernias). One hundred eighty-four patients (76%) underwent day-case surgery. There were no mesh infections or explanations, vascular or visceral injuries, port-site hernias, damage to testicle, or persisting numbness. There were no requirements for blood transfusion, returns to theatre, or readmissions within 30days. There was one conversion to open and one death within 60days of surgery. Eighty-three (34%) had a history of previous AP surgery. There was no significant difference in perioperative outcomes between the AP and non-AP arms. This finding carried true for subgroup analysis of 44 patients whose AP surgical history did not include previous inguinal hernia repair and for those undergoing repair of recurrent hernia. In expert hands, laparoscopic TEP repair is associated with excellent outcomes and low rates of long-term complications, and thus should be considered as standard for patients regardless of a history of AP surgery.

Evaluating a Single Surgeon's Learning Curve for Laparoscopic Totally Extraperitoneal Repair of Inguinal Hernia with Telescopic Dissection: A Cumulative Sum Control Chart Analysis.

Background: Laparoscopic totally extraperitoneal (TEP) inguinal hernia repair (IHR) reduces risk of injury to intraperitoneal structures. Balloon dissection is more costly and has theoretical risk of injury to the surrounding structures compared with telescopic dissection (TD). This study aims to evaluate the learning curve (LC) for TEP IHR with TD of a single surgeon. Methods: This is a 3-year retrospective cohort study from January 2020 to December 2022 on patients who underwent elective laparoscopic TEP unilateral IHR with TD. Exclusion criteria were recurrent inguinal hernia. Cumulative sum (CUSUM) analysis was performed to evaluate the number of cases required to surmount the LC, that is, NLC for operating time (OT) and open conversion. One way analysis of variance was used to perform groupwise comparison. Results: There were 69 patients who underwent laparoscopic TEP unilateral IHR with TD. The median age was 58.0 years (range 24.0-80.0) and body mass index was 23.0 (range 18.6-30.0). Majority of the hernia was indirect (n = 48, 69.6%). The median OT was 70 minutes (range 35-210). Three cases (4.3%) had open conversion. One-year recurrence was 4.2% (n = 1/24). CUSUM analysis showed improvement in OT after the eighth case. However, this was followed by multiple inflection points with no apparent stabilization in OT. Pairwise comparison showed a decrease in OT between cases 18-36 and cases 37-54. There was no incidence of open conversion until the 56th case. Conclusion: Laparoscopic TEP IHR using TD is safe in the absence of a practor. A minimum of 36 cases is required to surmount the initial LC.

Chronic Pain After Complete Extraperitoneal Inguinal Hernia Repair: A Randomised Controlled Trial Comparing Glue and Absorbable Tackers

Abstract: After having an inguinal hernia fixed, approximately 20% of people endure chronic pain. The underlying mechanism most likely involves sensory nerve damage and abnormal recovery, which may be influenced by the materials employed to secure the mesh. The major purpose of this study was to look at the impact of glue and absorbable tackers on the occurrence of residual discomfort after surgery in people who had totally extraperitoneal inguinal hernia repair (TEP). Methods: Patients having (TEP) inguinal hernia surgery were randomly assigned to either absorbable tackers (hold STRAP Johnson &amp; Johnson) or glue to hold the mesh (LIQUIBAND secure 8 Neopharm) in a single-blind clinical trial. A validated 4-point verbal-rank scale with the categories “none,” “mild,” “moderate,” and “severe” was used to score pain at one week, one month, six months, and a year after surgery. Chronic painful hernial location that persists for more than 6 months. Results: 218 patients were subjected to analyses. The groups differed just slightly in terms of age, gender, and hernia side. After 6 months, 31.7%(66/208) and 13%(29/208) of those who reported chronic pain of any intensity continued to do so, respectively. There were no different changes between the both categories in post surgery pain with the two methods, only patients suffering with significant discomfort, glue-using was still less uncomfortable than tacker-based fixation (log-rank p = 0.025). After a year, four symptomatic recurrence hernias were detected in individuals whose mesh was patched with absorbable tackers.

Comparative Review of Outcomes of Totally Extraperitoneal (TEP) and Transabdominal Preperitoneal (TAPP) Primary Inguinal Hernia Repair.

There is an ongoing debate about the efficacy and postoperative outcomes of transabdominal preperitoneal (TAPP) and totally extraperitoneal (TEP) inguinal hernia repair. Our aim is to assess the surgical outcomes of each technique, focusing predominantly on postoperative components to determine if establishing a policy to advocate for a single technique is warranted. A literary review of randomized control trials and cohort studies to delineate recurrent concerns or points of contention was undertaken. A retrospective, comparative analysis was performed of TEP and TAPP primary inguinal hernia repairs performed by surgeons with more than five-yearexperience with their preferred technique over a three-year period (January 2020 to December 2022) at three separate institutions. A total of 279 applicable cases were reviewed of which 38% (n=106) were performed as TEP and 62% (n=173) performed as TAPP. The demographic of the cohort was heavily skewed towards the male population as expected; however, there were no differences between each subgroup. TEP hernia repair showed a significantly improved postoperative pain score at one and 24 hours, respectively(1.67 ± 0.45, p < 0.05 and 1.97 ± 0.31, p < 0.05). No discernible difference was noted in the categories of length of hospital stay, recurrence rate, and overall patient satisfaction. The study showed overall improved results using the TEP inguinal hernia repair technique; however, no statistically significant results were demonstrated in the long term to advocate for changes to pre-existing surgeon preferences.

Safety of unfixed mesh in laparoscopic total extraperitoneal inguinal hernia repair: A meta-analysis of randomized controlled trials

BackgroundWhether the effect of the unfixed mesh during laparoscopic total extraperitoneal (TEP) inguinal hernia repair can lead to hernia recurrence remains controversial. MethodsThe PubMed, Cochrane Library, and EMBASE databases were searched to retrieve clinical randomized controlled trials (RCTs) comparing nonfixation of mesh and fixation of mesh in TEP inguinal hernia repair, and we performed a metaanalysis with RevMan 5.3 software. ResultsFifteen RCTs were included in the metaanalysis, which showed that the operation time (P = 0.001) of the unfixed mesh group was shorter than that of the fixed mesh group; additionally, the postoperative 24-h pain score (P = 0.04) and incidence of urinary retention (P = 0.001) were lower in the unfixed mesh group. There was no significant difference between the unfixed mesh group and the fixed mesh group in terms of hospital stay (P = 0.47), time to resume normal activities (P = 0.51), incidence of haematoma (P = 0.96), incidence of chronic pain (P = 0.20), and recurrence rate (P = 0.09). ConclusionUnfixed mesh in TEP inguinal hernia repair shows no elevated recurrence rates compared to fixed mesh and is clinically safe.

Feasibility of totally extraperitoneal inguinal hernia repair in patients with previous prostatectomy.

Laparoscopic totally extraperitoneal inguinal hernia repair (TEP) surgery technique includes three key steps: reaching the preperitoneal space, reducing hernias, and placement of mesh. However, reaching the preperitoneal space can be complicated in patients with previous lower abdominal surgeries. This study aimed to assess the feasibility of laparoscopic inguinal TEP in patients with previous prostatectomies. Inguinal hernia patients who underwent laparoscopic TEP between January 2015 and February 2021 at Koç University Faculty of Medicine, Department of General Surgery, were included in this retrospective study. The operations were performed by five senior surgeons experienced in laparoscopy. Patients were divided into two study groups, as the radical prostatectomy (RP) group which included patients with previous prostatectomy non-RP which included patients without previous radical prostatectomy. Operative time (OT), length of hospital stay (LOS), and postoperative complications were compared within two groups. Three hundred and forty-nine patients underwent laparoscopic TEP, and 27 had previous prostatectomies. Among them, 190 patients had unilateral inguinal hernias, and 159 had bilateral inguinal hernias. Mean age of the patients in the non-RP and RP groups was 58.1 ± 14.7 and 73.9 ± 9.6 years, respectively. Only one (3.7%) case was complicated with urinary tract infection in the RP group, and 10 (3.1%) were complicated in the non-RP group. Complications for the non-RP group include hematomas in six cases, urinary tract infection in three cases, and urinary retention in one case. No significant difference in mean operative time was seen between non-RP and RP groups (p= 0.43). There was no significant difference in the means of the length of hospital stay between the two groups (p= 0.7). Laparoscopic TEP in patients with a previous prostatectomy can be performed safely without prolonging the operative time and increasing the length of hospital stay.

A novel high accuracy model for automatic surgical workflow recognition using artificial intelligence in laparoscopic totally extraperitoneal inguinal hernia repair (TEP)

IntroductionArtificial intelligence and computer vision are revolutionizing the way we perceive video analysis in minimally invasive surgery. This emerging technology has increasingly been leveraged successfully for video segmentation, documentation, education, and formative assessment. New, sophisticated platforms allow pre-determined segments chosen by surgeons to be automatically presented without the need to review entire videos. This study aimed to validate and demonstrate the accuracy of the first reported AI-based computer vision algorithm that automatically recognizes surgical steps in videos of totally extraperitoneal (TEP) inguinal hernia repair.MethodsVideos of TEP procedures were manually labeled by a team of annotators trained to identify and label surgical workflow according to six major steps. For bilateral hernias, an additional change of focus step was also included. The videos were then used to train a computer vision AI algorithm. Performance accuracy was assessed in comparison to the manual annotations.ResultsA total of 619 full-length TEP videos were analyzed: 371 were used to train the model, 93 for internal validation, and the remaining 155 as a test set to evaluate algorithm accuracy. The overall accuracy for the complete procedure was 88.8%. Per-step accuracy reached the highest value for the hernia sac reduction step (94.3%) and the lowest for the preperitoneal dissection step (72.2%).ConclusionsThese results indicate that the novel AI model was able to provide fully automated video analysis with a high accuracy level. High-accuracy models leveraging AI to enable automation of surgical video analysis allow us to identify and monitor surgical performance, providing mathematical metrics that can be stored, evaluated, and compared. As such, the proposed model is capable of enabling data-driven insights to improve surgical quality and demonstrate best practices in TEP procedures.Graphical abstract

Use of the LigaSure for Closing Peritoneal Defects in an Experimental Rat Model

Background: There has not been an absolute consensus over the routine closure of peritoneal defect (PD) during laparoscopic totally extraperitoneal inguinal hernia repair (TEP). Pretied sutures, endoscopic stapling, and suturing are surgical techniques for closing PDs. Moreover, we observed that we could close small PDs during the TEP procedure by sealing with the LigaSure (LS). Objectives: The present study aimed to evaluate the necessity of closure PDs under a polypropylene mesh and the early intraperitoneal inflammatory, fibrotic, and adhesional effects of sealing PDs with the LS in an experimental rat model. Methods: A total of 35 male rats were assigned to five groups. 1- Control group: mesh was not used, and the peritoneum was left open; 2- Mesh group; mesh was placed directly on the PD without repairing, and three peritoneal repairing methods; 3- Stapling group: PD was repaired with metal clips; 4- Suture group: PD was repaired with Vicryl sutures; and 5- LigaSure group: PD was closed with the LS. Rats were sacrificed on the postoperative 14th day. Adhesion scores, fibrosis, and inflammation scores were compared between all groups. Results: All rats completed the 14 days of follow-up without complication. The Mesh group had significantly higher adhesion scores than the other groups (P&lt;0.001). Nonetheless, no significant difference was observed between peritoneal repairing methods (P=0.696). Fibrosis and inflammatory scores were similar in peritoneal repairing methods (P=0.394 and P=0.112, respectively). Conclusion: The direct contact of foreign bodies with the intra-abdominal organs increases the risk of adhesion; therefore, the remaining PDs under the polypropylene mesh should be repaired. Sealing PDFs with LS is a simple method that does not increase the inflammatory response, fibrosis, and the risk of adhesion formation.

Comparison of extraperitoneal and intraperitoneal laparoscopic procedures for intracranial pressure increase: a prospective clinical study.

According to the literature, higher levels of both intracranial pressure (ICP) and intraabdominal pressure (IAP) are related in a way that suggests a causal relationship. An increase in ICP can cause major neurological problems both during and after laparoscopic surgery. In this study, we aimed to examine the increase in ICP between totally extraperitoneal (TEP) inguinal hernia repair and laparoscopic cholecystectomy. We investigated 52 individuals who underwent laparoscopic surgery for the treatment of inguinal hernia (n = 26) or had a laparoscopic cholecystectomy (n = 26). The optic nerve sheath diameter (ONSD) was assessed before the procedure (T0), 10 minutes after carbon dioxide insufflation (T1), and immediately before extubation (T2). There were significant differences in the ONSD values between the two groups as a function of time (p = 0.001). In terms of ONSD, the laparoscopic cholecystectomy value (LV) group showed a greater shift from T0 to T1 and T2 than the inguinal hernia value (HV) group. At T1, the ONSD values of both groups were considerably higher than those of T0 and T2. The impact of the extraperitoneal and transperitoneal laparoscopic methods on ICP was investigated. The ONSD value reached its maximum at T1 in both groups. At all measurement periods, the ONSD values of the LV group were noticeably higher than those of the HV group. The diagnostic accuracy of ONSD ultrasonography is an important approach for determining the ICP level. During the decision-making process of TEP inguinal hernia repair, this study can guide medical professionals in the evaluation of elevated ICP.

Laparoscopic total extraperitoneal (TEP) inguinal hernia repair with preperitoneal closed-suction drainage reduced postoperative complications

BackgroundAlthough laparoscopic total extraperitoneal (TEP) inguinal hernia repair has the advantages of less bleeding, less trauma, less pain, and fast recovery, there are several issues that need to be addressed. This study aims to evaluate the effectiveness of preperitoneal closed‑suction drainage on reducing postoperative complications in TEP inguinal hernia repair.MethodsA retrospective analysis of 122 patients who underwent TEP inguinal hernia repair between June 2018 and June 2021 was performed. The patients were divided into the drainage group and the non-drainage group according to whether the drainage tube was placed or not. Clinical data, surgical procedures and outcome of these patients were collected and analyzed to assess the effectiveness of drainage.ResultsA total of 122 patients undergoing TEP surgery were screened, of which 22 were excluded. Most of the patients were male with right indirect inguinal hernia. There was no difference in the mean length of hospital stay between the two groups. Postoperative pain was alleviated by preperitoneal closed‑suction drainage 24 h after operation (p = 0.03). The rate of complications such as scrotal edema, seroma and urinary retention in the drainage group was significantly lower than that in the non-drainage group (p < 0.05). Multivariate regression analysis showed that drainage was beneficial to reduce postoperative complications (OR, 0.015; 95% CI, 0.002–0.140; p < 0.01). In addition, it was worth noting that in subgroup analysis, patients with hernia sac volume > 10 cm3 might receive more clinical benefits by placing drainage tube.ConclusionIn TEP inguinal hernia repair, placing drainage tube is a simple and feasible traditional surgical treatment, which can promote postoperative recovery without increasing the risk of infection, especially in patients with large hernia sac volume.

Total extra-peritoneal inguinal hernia repair: experience in a tertiary care hospital of Bangladesh

Background: Open hernioplasty, a traditional procedure, is practiced for decades all over the world, for inguinal hernia repair and the newer procedure of total extraperitoneal (TEP) inguinal hernia repair is the current trend. Aim of this study was to share the experience of TEP inguinal hernia repair.&#x0D; Methods: This retrospective observational study was done from April, 2012 to March, 2021 at BIRDEM General Hospital, Dhaka, Bangladesh. Patients with inguinal hernia reporting to BIRDEM outpatient department (OPD) were counseled for TEP repair. Those who consented were treated electively with a TEP repair for a unilateral or bilateral hernia defect, either direct or indirect. All procedures were completed with patients under general anaesthesia. Polypropylene mesh was placed in preperitoneal space. Followed up records were noted at one week, one month, one and two years after surgery. Patients’ age, hernia types and locations, complications, length of stay in hospital, return to work and recurrence were noted.&#x0D; Results: Total patients were 118 including one female. Patients were between 22 and 72 years. All of them had primary hernias and 72% of them underwent unilateral repairs. One of the cases required conversion to transabdominal preperitoneal procedure. In five patients (4.2%) intraoperative complication occurred and postoperative courses were complicated in 8 patients (6.7%). Patients were able to resume their daily activities after a mean period of 7 days (3 to 10 days). There was no mortality.&#x0D; Conclusion: In patients with uncomplicated inguinal hernias, TEP is associated with a very low overall risk of serious complications and recurrence with a very good functional outcome. It is equally applicable with bilateral inguinal hernias without added risk.&#x0D; BIRDEM Med J 2023; 13(1): 44-48

Endoscopic totally extraperitoneal repair for groin hernia: Experience from a tertiary care centre.

Totally extra-peritoneal (TEP) and transabdominal preperitoneal (TAPP) repair are two established minimal access techniques of groin hernia surgery. TEP offers the advantage of avoiding violation of the peritoneal cavity. This study aims to describe the decade-long experience of TEP in groin hernia repair in a tertiary care teaching institute and the feasibility of the same in difficult scenarios. Retrospective analysis of the database of patients undergoing TEP repair for inguinal hernia in a single surgical unit at a tertiary teaching hospital between January 2008 and December 2019 was performed. Detailed pre-operative clinical details, operative duration, intraoperative and post-operative complications, including pain, length of post-operative hospital stay and hernia recurrence data were analysed. Over 12 years' duration, 511 patients underwent endoscopic TEP mesh repair and the total number of hernias repaired was 614. Majority (97.45%) of patients were male. The mean age of the patient population was 51.3 years. Primary hernia was seen in 490 patients. The mean operating time for unilateral inguinal hernia repair was 56.8 ± 16 min and for bilateral repair 80.9 ± 25.2 min. TEP in previous lower abdominal/suprapubic surgical scars was attempted in 17 (3.3%) patients, with only one requiring conversion. The intraoperative peritoneal breach was the most common documented complication (34.8%). Seroma was seen in 9.4% of patients. Seventeen patients required conversion (14 TAPP and 3 open). Recurrence was seen in 4 (0.7) patients. TEP repair is an effective method of groin hernia repair and can be attempted in the majority of patients groin hernia, including patients with previous lower abdominal incisions.

Nonfixation of mesh in laparoscopic totally extraperitoneal inguinal hernia repair: A propensity score matched analysis

BackgroundRegarding the need for mesh fixation in total extraperitoneal inguinal hernia repair (TEP), several studies have found no significant differences in the recurrence rate between patients with and without fixation. Furthermore, there is no report on the outcome of this treatment from Japan. We aimed to analyze the outcomes of nonfixation TEP with those of fixation at our institute. MethodsIn May 2016, the nonfixation TEP technique was launched. The fixation group (165 patients) was compared to the nonfixation group (195 patients). Because of the significant bias between the two groups, a propensity score matched analysis was performed (with 109 patients in each group). Moreover, only ordinary cases (with 58 patients in each group) were compared, excluding bilateral, large, and impaction cases. ResultsOne patient in the nonfixation group experienced recurrence. It was a hernia case with a large orifice. In the fixation group, seroma was more prevalent; however, no differences were observed between the two groups in propensity score matching. In unilateral cases, the nonfixation group had a shorter operation time and stayed in the hospital for a shorter time postoperatively. The ordinary cases, excluding cases of bilateral hernias, large hernias on visual examination, impactions, and large hernial orifices, showed no recurrence or significance in surgical complications. ConclusionsThe nonfixation TEP was considered acceptable at least for ordinary hernial cases.

Laparoscopic total extra-peritoneal (TEP) inguinal hernia repair under local anesthesia by topical lidocaine injection.

Laparoscopic total extra-peritoneal (TEP) inguinal hernia repair is usually performed under general anesthesia (GA) for muscle relaxation. However, TEP hernia repair may be reluctant in high-risk patients of GA. The aim of this study was to compare the outcomes of the TEP under GA and local anesthesia (LA). We retrospectively analyzed patients with inguinal hernia who underwent TEP under GA or LA in a single center from December 2016 to May 2018. The outcomes, such as demographics, duration of surgery, length of hospital stay, visual analog scale (VAS), and postoperative complications, were compared in each group. Seventy-six patients with inguinal hernia underwent TEP under GA (n = 52) or LA (n = 24). Total operation time (mean ±standard deviation; GA, 111.6 ± 23.0min; LA, 76.3 ± 18.0min; p < 0.001) and length of hospital stay (GA, 38.3 ± 11.6min; LA, 30.3 ± 15.6min; p < 0.014) were shorter in LA group compared to GA group. There were no significant differences in postoperative VAS (1h, p = 0.247; 4h, p = 0.086; 12h, p = 0.469; 24h, p = 0.411), postoperative adverse effects (vomiting, p = 0.570; urinary retention, p = 0.214; headache, p = 0.494), and postoperative complications (seroma, p = 0.348; scrotal edema, p = 0.178; recurrence, p = 0.822) between LA group and GA group. Compared with GA, there were no differences in postoperative pain and complications in patients who underwent TEP hernia repair under LA. Furthermore, in LA group, total operation time and length of hospital stay were shortened.

Early Results of Comparison of Hydrophilic Anatomical Mesh and Polypropylene Mesh for Laparoscopic Total Extraperitoneal (TEP) Inguinal Hernia Repair.

To compare the results, feasibility, and effectiveness of laparoscopic total extraperitoneal (TEP) hernia repair made using anatomical hydrophilic mesh and polypropylene mesh. Descriptive study. Department of General Surgery, Recepc Tayyip Erdoğan University Training and Research Hospital, Rize, Turkey and Department of General Surgery, Ondokuz Mayıs University Medical Faculty, Samsun, Turkey from January 2017 to October 2020. Comparative analysis on patient who had TEP for inguinal hernia. Group 1 included repairs using hydrophilic anatomical mesh, Group 2 included repairs using polypropylene mesh. Both were compared for operation times, complications, and return to work. There were 34 patients in Group 1 and 31 patients in Group 2. The average operation time was shorter in Group 1 (p = 0.001). Postoperative complications, were significantly less common in Group 1 (p = 0.045). Patients were able to return to their work-life earlier in Group 1 after surgery (p = 0.001). Both anatomic mesh and polypropylene mesh can be used in TEP hernia repair. These two materials stand out with their different properties. Whereas anatomical mesh shortens the operation time, decreases the rate of postoperative complications, and enables the early return to work, polypropylene mesh is cost-effective and easily accessible. Inguinal hernia, Postoperative complication, Laparoscopic total extraperitoneal (TEP).

Surgical outcomes of laparoscopic total extraperitoneal (TEP) inguinal hernia repair compared with Lichtenstein tension-free open mesh inguinal hernia repair: A prospective randomized study.

Inguinal hernia repair is one of the most frequently performed surgery. The ideal procedure for inguinal hernia repair remains controversial. Open Lichtenstein tension-free mesh repair (LMR) is one of the most preferred open techniques with satisfactory outcomes. Laparoscopic approach in inguinal hernia surgery remains controversial, especially in comparison with open procedures. In this study, we have reported a comparison of laparoscopic total extraperitoneal (TEP) inguinal hernia repair with LMR. Postoperative pain, operative time, complications like seroma, wound infection, chronic groin pain, and recurrence rate were parameters to evaluate the outcome.One hundred seventy-four patients were included in the study by consecutive randomized prospective sampling. The patients were divided into 2 groups: group A, laparoscopic TEP inguinal hernia repair, and group B, LMR. The procedures were performed by experienced surgeons. The primary outcomes were evaluated based on postoperative pain and recurrence rate. Secondary outcomes considered for evaluation were operative time, complications like seroma, infection, and chronic groin pain.Severe pain was reported in group A (7.9%) compared to group B (15.1%), which was statistically significant (P < .001). Moderate pain was reported more in group B (70.9%) compared to group A (29.5%) (P < .001). The mean operative time in group A was 84.6 ± 32.2, which was significantly higher than that in group B, 59.2 ± 14.8. There was no major complication in both groups. The chronic pain postoperatively was significantly in higher number of patients in group B vs group A (22.09% vs 3.4%). The postoperative hospital stay period was significantly lesser for group A vs for group B (2.68 ± 1.52 vs 3.86 ± 6.16). Time duration taken to resume normal activities was significantly lower in group A (13.6 ± 6.8) vs (19.8 ± 4.6) in group B (P < .001).Although there is definite evidence of longer operative time and learning curve, laparoscopic TEP has added advantages like less postoperative pain, early resumption of normal activities, less chronic groin pain, and comparable recurrence rate compared to open Lichtenstein repair. Laparoscopic TEP can be performed with acceptable outcomes and less postoperative complications if performed by experienced hands.

A prospective randomized study of eTEP and TEP repair for inguinal hernia in terms of ease of operability, complication and recurrences

Background: Inguinal hernia is one of the diseases that has haunted humanity from its very beginning to the modern times. Groin hernias are the most common conditions referred to surgeons all over the world and over five lakh hernia repairs are performed annually. The lifetime risk for men is 27.0% and for women is 3.0%. Approximately 75.0% of all abdominal wall hernias occur in the groin. Inguinal hernias are more common on the right than on the left and are seven times more likely in males than in females. Aims and Objectives: Aim and objective of the study is to compare extended total extra peritoneal (e-TEP) and total extra peritoneal (TEP) repair in terms of complications and recurrence. To evaluate ease of operability of e-TEP and TEP for inguinal hernia repair. Materials and Methods: Patients with inguinal hernia who were hospitalized to the Department of General Surgery at GSVM Medical College, Kanpur, and who were over the age of 18 years of both sexes were studied from December 2019 to October 2021 after signing a consent form. The research procedure followed was in accordance with the approved ethical standards of GSVM Medical College, Kanpur, UP, India Ethics Committee (Human). Data were analyzed and evaluated using Statistical Package for Social Sciences, version 23 (SPSS Inc., Chicago, IL). Results for continuous variables are shown as mean ± standard deviation, whereas results for categorical variables are shown as number (percentage). For comparison of nominal data, Chi-square (χ2) test was used. The level P&lt;0.05 was considered as the cut-off value of significance. Results: Majority of the patients of Group TEP (25 patients) had complications as Conversion to trans abdominal pre-peritoneal (TAPP) 4 (16.0%) and proceed surgery without veress needle decompression 2 (8.0%). In Group eTEP (25 patients) majority of patients had complications as proceed surgery without veress needle decompression 8 (32%) followed by Seroma 2 (8.0%). No recurrences seen in either groups. Mean operative time of eTEP was less as compared to TEP. Conclusion: With TEP, complications such as SSI, hematoma, and conversion to TAPP are more common; however with eTEP, proceed surgery without veress needle decompression and seroma. Considering the average operative time of eTEP and TEP, as well as the bigger defect size that eTEP can readily handle. For new surgeons, eTEP is a more straightforward procedure. Moreover, our study findings showed that e-TEP mesh repair of inguinal hernia showed more firm and efficacious results than TEP repair. We suggest that long-term randomized control trials with enhanced sample size and reduced confounding factors are still required to establish the absolute superiority of e-TEP over TEP.

Effects of neuromuscular blockade on the surgical conditions of laparoscopic totally extraperitoneal inguinal hernia repair: a randomized clinical trial.

Unlike other laparoscopic techniques, the peritoneum is not incised in laparoscopic totally extraperitoneal inguinal hernia repair (TEP), and the preperitoneal space is developed as the surgical field by blunt dissection and CO2 insufflation. While many studies have investigated the effect of neuromuscular blockade (NMB) on the surgical conditions and postoperative pain of laparoscopic intraperitoneal surgery, few studies have investigated those of TEP. In the present study, we investigated the effect of NMB on the surgical conditions and postoperative pain of TEP. Forty-two adult patients scheduled for unilateral TEP under general anesthesia with remifentanil and desflurane were randomly assigned to paralyzed or non-paralyzed groups. In the paralyzed group, rocuronium doses were administered to maintain post-tetanic count at ≤ 5 during surgery. Non-paralyzed subjects were not given any rocuronium. Postoperatively, surgeon-evaluated surgical conditions, assessed using a 100-mm visual analogue scale ranging from 0mm (not acceptable) to 100mm (excellent), were compared between the two groups. For evaluation of postoperative pain, the time from the end of anesthesia to the initial requirement of postoperative analgesia was compared by the log-rank test. Median [interquartile range] score of surgical condition in the paralyzed and non-paralyzed groups were 84 [75-90] and 84 [78-87], respectively (P = 0.46). Significant differences in postoperative analgesic requirements between the two groups were not confirmed (P = 0.74). NMB did not improve the surgical conditions nor reduce postoperative pain. NMB is not routinely needed for TEP just because it is a laparoscopic procedure. The trial was registered in the UMIN clinical trials registry (UMIN000029683, October 24, 2017; Principal investigator: Masafumi Fujimoto, https://upload.umin.ac.jp/cgi-open-bin/ctr/ctr_view.cgi?recptno=R000033920 ) prior to patient enrolment.
