Unilateral Inguinal Hernia Repair Research Articles

Quality of life following Shouldice Repair: a prospective cohort study among inguinal hernia patients.

The aim of this study was to evaluate quality of life from the preoperative time to six months after surgery of patients who underwent a Shouldice Repair for primary inguinal hernia. After ethical approval, consent was obtained, and data collected from surveys and chart review. The study population was composed of male and female patients aged 16-90years of age, who had a Shouldice Repair of a primary unilateral inguinal hernia. The EQ-5D-3L, a questionnaire applied to hernia surgery in Canada, was used to determine quality of life at the preoperative and 1week, 1- and 6-month postoperative time. Data analysis included descriptive statistics, as well as inferential analysis. From January 2023 to February 2024, 532 participants met the criteria, completed and returned the preoperative survey, and underwent primary inguinal hernia repair. The participants were mostly male (94%) with an average age of 62.18years and BMI of 24.93kg/m2. The EQ-5D-3L health index scores and EQ-VAS health status at preoperative were 0.83 ± 0.13 and 79.5 ± 12.59. At the 1-month postoperative time, health index scores and health status had significantly increased from preoperative (score:0.91 ± 0.12, p = .001; status 83.56 ± 12.93, p = .001), and continued to significantly increase from baseline at the 6-month postoperative time (score:0.95 ± 0.10, p = .001; status:85.25 ± 12.17, p < .001). Quality of life, as measured by the ED-5D-3L health index score, significantly improved for patients that underwent a Shouldice Repair for an inguinal hernia.

Comparative Analysis of Ultrasound Guided Transversus Abdominis Plane Block with or without Buprenorphine Following Inguinal Hernia Repair

Background and Aims Inguinal hernia is a commonly performed surgical procedure globally, which is often accompanied by significant post-operative pain that peaks on the day of the surgery. The transversus abdominis plane block (TAP) offers better postoperative pain relief for lower abdominal procedures. However, the duration of TAP block is restricted by the effects of given local anaesthetic drugs, necessitating the use of an adjuvant, such as buprenorphine, to improve the quality and duration of analgesia. Hence, we designed the present study to analyse the effect of a TAP block with buprenorphine on the relief of pain after inguinal hernia repair surgery. Methods A prospective, randomized, double-blinded study was conducted on fifty American Society of Anaesthesiologists Physical Status I and II patients posted for elective unilateral inguinal hernia repair under spinal anaesthesia. At the end of the surgery, group B patients received 20 ml of 0.25% bupivacaine and group BB patients received 20 ml of 0.25% bupivacaine along with 300 mg of buprenorphine for ultrasound-guided transversus abdominis plane block. The duration of analgesia, postoperative analgesic consumption and pain scores at rest and during sitting up to 24 h were recorded. Results Patients who received perineural buprenorphine experienced prolonged duration of analgesia (870.32 ± 27.86 vs. 385.64 ± 27.86 minutes), lower tramadol consumption (135.08 ± 23.05 vs. 246.72 ± 38.8 mg), and decreased pain scores both at rest and during sitting for up to 24 hours post-surgery. Conclusion The present study shows that the addition of buprenorphine to bupivacaine in TAP block after inguinal hernia repair produces superior postoperative analgesia compared with the control group without any significant side effects.

Comparison of ilioinguial/iliohyphogastic nerves block with woundinfiltration on postoperative pain: A randomised controlled trial.

To compare postoperative pain scores at rest and on movement in patients undergoing open inguinal hernia repair between those receiving illioinguinal/illiohypogastric nerve block with ropivacaine or wound infiltration with ropivacaine. The randomised clinical trial was conducted at the Department of Anaesthesiology, Aga Khan University Hospital a tertiary care centre from March to August 2019 and comprised patients of either gender scheduled for elective unilateral open inguinal hernia repair under general anaesthesia. They were randomised into illioinguinal/illiohypogastric nerve block group A, and wound infiltration group B. In group A, 20 ml of 0.25% ropivacaine was infiltrated in the vicinity of the nerves under ultrasound guidance, while group B received wound infiltration with ropivacaine 10ml 0.25% at the end of surgery. Postoperative static and dynamic pain was assessed at 0, 2, 6, 12 and 24 hours using visual analogue scale. Total usage of opioids in 24 hours postoperatively in both groups, patient satisfaction and complications were recorded. Data was analysed using SPSS 19. Of the 60 patients, 30(50%) were in each of the 2 groups. There were 29(96.7%) males and 1(3.3%) female in group A with mean age 45.63±17.43 years, and 28(93.3%) males and 2(6.7%) females in group B with mean age 49.33±15.39. The mean pain score at rest was not significantly different between the groups (p>0.05). On movement, the mean pain score between the groups was different only at 6 hours (p=0.02). There were no significant intergroup difference in total usage of opioids in 24 hours postoperatively and patient satisfaction (p>0.05). Illioinguinal/illiohypogastric nerve block and wound infiltration with ropivacaine were found to be equally effective methods in controlling postoperative pain. NCT04462510.

A Data-Driven Approach to Inguinal Hernia Repairs in Infants and Children.

Introduction: Laparoscopic inguinal hernia repair has become increasingly popular in children. The laparoscopic technique inherently assesses the contralateral processus vaginalis, reducing the risk of metachronous contralateral hernias. We hypothesized that primary laparoscopic repair would be associated with lower rates of subsequent hernia repair in the youngest patients, in whom metachronous contralateral hernias are most common. Materials and Methods: The Pediatric Health Information System database was queried for patients 0-15 years old, who underwent inguinal hernia repair between 2016 and 2022. The primary outcome was the need for subsequent hernia repair. Current Procedural Terminology (CPT) and ICD-10 procedure codes were used to determine laparoscopic versus open repair. Patients were excluded if the only recorded code was for recurrent hernia or if both laparoscopic and open codes were present for the same procedure. Results: A total of 109,456 patients were included in the study, with 20,338 patients (18.58%), undergoing laparoscopic inguinal hernia repair initially, and 2535 patients (2.32%) requiring a second hernia repair. Patients 6 months old and younger undergoing unilateral laparoscopic repair were less likely to require subsequent surgery (OR 0.82, 95% CI = 0.69-0.96). Across all ages, open bilateral repair less often required subsequent repairs (OR 1.93, 95% CI 1.48-2.51). Conclusion: Laparoscopic unilateral inguinal hernia repair decreases the need for subsequent surgical repair in infants 6 months and younger. No difference was detected in older patients. Open repair of bilateral hernias decreases the need for a second hernia operation in all age groups, suggesting that open repair is more durable.

Comparing the Postoperative Analgesic Efficacy of Ketorolac and Tramadol After Open Inguinal Hernia Mesh Repair: A Randomized Controlled Trial.

Background Opioids are the mainstay for postoperative pain control. However, due to the increasing dependence on opioids and their side effects, multiple adjuncts are used to reduce opioid consumption, including non-steroidal anti-inflammatory drugs (NSAIDs). Inguinal hernia repair is one of the most common procedures performed by general surgeons worldwide. Despite various advancements in operative techniques, postoperative pain remains a major risk factor for morbidity and delayed hospital discharge following surgery. Objective The objective of this study was to compare ketorolac with tramadol for postoperative pain control following open inguinal hernia mesh repair. Methods This was a randomized controlled trial. Sixty patients undergoing unilateral primary open inguinal hernia repair with mesh were randomly divided into two groups: Group A received injection ketorolac intravenously postoperatively, while Group B received injection tramadol intravenously following surgery. Pain scores and vitals were measured at two, six, 12, and 24 hours post procedure. Other secondary outcomes included the time for nausea to stop, time to pass flatus, and time to start ambulation. Data was analyzed by independent-sample t-test using IBM SPSS Statistics for Windows, Version 30.0 (Release 2024; IBM Corp., Armonk, New York, United States); a p-value of < 0.05 was considered significant. Results Pain scores were lower in the ketorolac group when compared to tramadol. However, patients in the tramadol group had nausea for a longer duration, delayed return of bowel function, and took longer to start ambulation. There was no significant difference in vitals. Conclusion Injection ketorolac, when used in isolation, provides more effective postoperative analgesia along with fewer side effects when compared to tramadolin inguinal hernia repair.

Ultrasound Guided Ilioinguinal/Iliohypogastric Nerve Block versus Transversus Abdominis Plane Block in Pain Management Following Unilateral Inguinal Hernia Repair

Abstract Background Poorly controlled acute pain after abdominal surgery is related to somatic pain signals derived from the abdominal wall and is associated with a variety of unwanted post-operative consequences, including patient suffering, distress, respiratory complications, delirium, myocardial ischemia and prolonged hospital stay. Aim of the Work The aim of this study was to assess the postoperative analgesic efficacy of TAP block compared to IIN+IHN nerves block after unilateral inguinal hernia repair regarding the pain relief, effect on hemodynamics, requirement of first supplemental doses of analgesia and total number of doses received. Patients and Methods The study was conducted on 64 randomly chosen patients American Society of Anesthesiologists (ASA) class I or II scheduled for elective unilateral open inguinal hernia repair under general anesthesia in Ain Shams University Hospitals after approval of the medical ethical committee. They were allocated in two groups. Results The study revealed that patients received IIN+IHN block had significantly lower pain scores after operation, delayed time for rescue analgesia and decreased total need of analgesic in the first 24hrs post- operative compared to patients who received TAP nerves block. Conclusion IIN+IHN block was effective in reducing postoperative pain scores, lowering total 24-h postoperative opioid and analgesic consumption and delaying the need for rescue analgesia after inguinal hernia repair under general anesthesia, compared to TAP nerves block.

Comparison between Preoperative Ultrasound Guided TAP Block and Caudal Block in Inguinal Hernia Repair in Paediatrics for Intraoperative and Postoperative Analgesia

Abstract Background Inguinal hernia repair is the most common scheduled sub-umbilical surgery done in day case paediatric surgical units. Using optimal analgesic regimens is essential to provide safe and effective analgesia, reduce postoperative stress response and accelerate recovery from surgery. Regional anaesthetic techniques are commonly used to facilitate pain control in paediatric surgical procedures. Aim of the Work To compare the effectiveness and safety of US guided TAP versus caudal block for postoperative analgesia in paediatric patients undergoing Unilateral Inguinal hernia repair. Patients and Methods The study was conducted on 40 randomly chosen patients in Ain Shams University Hospitals after approval of the medical ethical committee. Patients were divided randomly into two groups, each group consisted of 20 patients. After preoperative assessment and obtaining baseline vital data, all patients received general anaesthesia followed by the block at the beginning of the operation. Results the study revealed that US guided TAP block provided significantly prolonged postoperative analgesia and reduced the postoperative analgesic requirements as compared with caudal block in paediatric patients and also demonstrated that both analgesic techniques are safe. Conclusion From our study we can conclude that Ultrasound-guided transversus abdominis plane block and caudal epidural block are effective analgesics in children undergoing inguinal hernia repair surgery, with transversus plane block providing longer analgesic effect and decreased pain scores.

Matching males and females undergoing non mesh primary unilateral inguinal hernia repair: evaluating sex differences in preoperative and acute postoperative pain.

The objective was to compare pain and related psychological factors during the preoperative and acute postoperative period between male and female patients, who underwent non mesh primary unilateral inguinal hernia repair. After ethics approval, informed consent was obtained, and data were collected. Male and female participants were compared by manually matching one-to-one on 10 variables. Descriptive statistics (mean ± standard deviation and frequency) as well as numerical rating scales from 0 to 10 were used. Comparison tests were performed using Chi-square or Fisher's Exact test for categorical data and independent samples t-test or non-parametric equivalent tests for numerical scores. p < 0.05 is reported as statistically significant. To control type I error, Bonferroni correction was used. 72 participants with 36 matched pairs were included. Sex differences were found for operation length (p = .006), side of operation (p = .002), and hernia type (p = .013). Significant differences between the sexes were not found at the preoperative or postoperative time for resilience, pain interference or pain severity related measures, postoperative hernia pain incidence, pain catastrophizing, depression and anxiety symptoms, or return to normal activities. When controlling for known confounders and using a conservative Type I error rate, pain and related factors between the sexes did not differ significantly.

Polypropylene vs. stainless-steel wire suture: short-term recurrence rate after shouldice primary inguinal hernia repair, a non-inferior analysis among 1120 patients. A case–control study

IntroductionPolypropylene material is commonly used for posterior wall reconstruction in hernia repair, in contrast with the classically described stainless-steel wire used at Shouldice Hospital. This study was conducted to evaluate possible differences in Shouldice Repair outcomes using polypropylene or stainless-steel wire sutures.MethodsA prospective follow-up of consecutive patients who underwent elective unilateral Shouldice primary inguinal hernia repair at Shouldice Hospital between December 6, 2021, and September 1, 2022, was conducted. Data was collected from follow-up telephone calls as well as manually reviewing patient's charts. The primary objective was to determine whether the use of polypropylene was non-inferior to the use of stainless-steel wire, regarding the recurrence rate reported by the patients with a minimum follow-up of 1 year after Shouldice primary inguinal hernia repair.ResultsA total of 1120 patients were contacted by telephone (polypropylene: 560; stainless-steel wire: 560). The median follow-up period was 16 months (interquartile range: 15–18). In 22 (1.96%) cases a surgical site infection was diagnosed. There was a total of 18 recurrences reported by the patients (1.6%). There was no statistical difference between the groups (polypropylene: 7 (1.25%) vs. stainless steel wire: 11 (1.96%), p > 0.05) for the recurrence rate.ConclusionThe use of polypropylene is non-inferior to the use of stainless-steel wire regarding recurrence rate at a median follow-up period of 16 months after elective unilateral Shouldice primary inguinal hernia repair. This finding may encourage other centers where stainless-steel wire is not easily available to perform the Shouldice Repair.

Incidence of contralateral metachronous inguinal hernia on long term follow-up after unilateral inguinal hernia repair: a systematic review and meta-analysis.

The repair of inguinal hernias is a common surgical procedure. Some patients will need a second operation after developing a metachronous contralateral inguinal hernia (MCIH). The suggestion has been made to strengthen the contralateral side at the same time as primary unilateral surgery. In this systematic review we aim to determine how many adult patients with a unilateral inguinal hernia will develop a MCIH. This review was reported in line with PRISMA guidelines. We performed a literature review in PubMed Publisher, Embase, Google Scholar and Cochrane Library until May 2021, including articles reporting MCIH after unilateral inguinal hernia repair in adults. As outcome measure, the number of patients diagnosed with a MCIH was registered. A total of 19 articles with a total of 277,288 patients were included. The combined estimate for MCIH after meta-analysis equaled 8.3% (95% CI 7.1%-9.5%), with a high index of heterogeneity (I2 = 97.9%). A random-effects meta-regression was performed to obtain the percentage of MCIH as a function of median follow-up time. The percentage of MCIH at 3, 5 and 10years was estimated at 5.2%, 8.0% and 17.1%, respectively. We suggest that there is insufficient clinical evidence to support prophylactic contralateral repair in all patients. We propose a patient-specific approach in the decision to perform prophylactic repair, taking into account potential risk factors for hernia development, type of surgical approach, and general risk factors for chronic postoperative inguinal pain. More long-term prospective data are needed to guide the decision for prophylactic contralateral mesh placement.

Preoperative CT findings predict the development of metachronous contralateral inguinal hernia after unilateral inguinal hernia repair: a single-center retrospective cohort study.

To identify potential clinical and preoperative CT risk factors that can predict the development of metachronous contralateral inguinal hernia (MCIH) after unilateral inguinal hernia repair (IHR). This study included unilateral inguinal hernia patients seen from 2016 to 2019 who underwent CT and subsequent IHR and had at least five years of follow-up. Preoperative CT scans were retrospectively reviewed for the presence of asymmetric spermatic cord fat and weakness of the transversalis fascia. The correlations of each CT feature and other clinical characteristics with the development of MCIH were calculated. The Kaplan-Meier model and multiple logistic regression were used to evaluate the associations among CT features, clinical variables and MCIH. A total of 677 male patients aged > 40 years were included in the study cohort. After more than 5 years of follow-up, 162 patients developed MCIH, representing an incidence of 23.9%. Patients with radical prostatectomy or peritoneal dialysis [P < 0.0001, HR 4.189 (95% CI 2.369 to 7.406)], primary left-sided IHR [P = 0.0032, HR 1.626 (95% CI 1.177 to 2.244)], and direct, femoral or pantaloon hernias were predisposed to MCIH. Asymmetric spermatic cord fat [P = 0.0002, HR 1.203 (95% CI 0.8785 to 1.648)] and weakness of the transversalis fascia [P < 0.0001, HR 7.914 (95% CI 5.666 to 11.05)] on preoperative CT were also identified as risk facts and demonstrated to be independent predictive factors for MCIH development. Asymmetric spermatic cord fat and weakness of the transversalis fascia were predictive factors for MCIH development. For decision making regarding prophylactic contralateral IHR at the time of index surgery, preoperative CT findings as well as clinical characteristics should be considered.

Use of the Desarda Technique versus the Lichtenstein Technique for the Repair of Unilateral Inguinal Hernia: An Updated Systematic Review and Meta-analysis

Use of the Desarda Technique versus the Lichtenstein Technique for the Repair of Unilateral Inguinal Hernia: An Updated Systematic Review and Meta-analysis

Bupivacaine/Dexmedetomidine versus Bupivacaine Alone in Caudal Block for Toddlers Undergoing Unilateral Open Inguinal Hernia Repair

Abstract Background Unilateral open inguinal hernia repair surgeries are one of the most frequently performed operations in the pediatric population. Regional anesthetic techniques are commonly used for better control of pain in pediatrics. the most widely used technique of regional anaesthesia in pediatrics is the caudal block. Objective To evaluate the analgesic and sedative effect of dexmedetomedine when given caudally as an adjuvant to bupivacaine in caudal block vs bupivacaine alone in toddlers undergoing unilateral Open inguinal hernia repair surgeries. Patients and Methods The study was conducted on 50 randomly chosen patients in Ain Shams University Hospitals after approval of the medical ethical committee. Patients were divided randomly into two groups; each group consisted of 25 patients. After preoperative assessment and obtaining baseline vital data, all patients received general anesthesia. Results The result of the study reveals that the addition of dexmedetomedine at 1μg/kg to bupivacaine 0.25% in caudal blocks can effectively prolong the duration of postoperative analgesia and causes better sedation than using bupivacaine alone in caudal blocks at similar doses in pediatrics. Conclusion From our study we can conclude that the addition of dexmedetomedine at 1μg/kg to bupivacaine 0.25% in caudal blocks can effectively prolong the duration of postoperative analgesia and causes better sedation in the toddlers undergoing unilateral open inguinal hernia repair surgeries. It is better than using bupivacaine alone in caudal blocks at similar doses.

A Comparative Study between Ultrasound Guided Ilioingunial/Iliohypogastric Nerve Block versus Transversus Abdominis Plane Block in Patients Undergoing Unilateral Oblique Inguinal Hernia Repair

Abstract Background Combined ilioinguinal-iliohypogastric (IIN/IHN) block and transversus abdominis plane (TAP) block are used under ultrasound (USG) visualization for postoperative pain control in patients undergoing unilateral inguinal hernia repair surgery. Patients and Methods This study compares USG-guided TAP versus IIN/IHN block for post-operative analgesia efficacy in adults undergoing inguinal hernia surgery, among 60 patients randomized into group A received IIN+IHN blocks by using levobupivacaine 0.25% 20 ml and group B received TAP block by using levobupivacaine 0.25% 20 ml after induction of general anesthesia. Results There is highly statistically significant increase mean of ilioinguinal /illiohypogastric block (II/IH) group compared to TAP block group according to time to rescue analgesia (min) (p &amp;lt; 0.001). Conclusions USG-guided IIN/IHN block delays the need for rescue analgesia and reduces the postoperative analgesic requirement compared to USG-guided TAP block.

A Comparative Study Between Ultrasound-Guided Ilioingunial/Iliohypogastric Nerve Block versus Transverse Abdominis Plane Block in Patients Undergoing Oblique Inguinal Hernia Repair

Abstract Background Poorly controlled acute pain after abdominal surgery is related to somatic pain signals derived from the abdominal wall and is associated with a variety of unwanted post-operative consequences, including patient suffering, distress, respiratory complications, delirium, myocardial ischemia and prolonged hospital stay. Objective Regional anesthesia by (Ultrasound guided (US) Transversus abdominis plane block (TAP) or Ultrasound guided ilioinguinal and iliohypogastric nerves (IIN+IHN) block may be used as components of multimodal anesthesia with a comparable effect. In the present study, Bupivacaine is used to compare between them following inguinal hernia repair. Patients and Methods The study was conducted on 60 randomly chosen patients aged above 18 years, American Society of Anesthesiologists (ASA) class I or II scheduled for elective unilateral open inguinal hernia repair under general anesthesia, in Ain Shams University Hospitals after approval of the medical ethical committee. They were allocated in two groups. TAP block Group: received general anesthesia and (0.2 mL/kg of 0.25% bupivacaine per side), by midaxillary approach, under ultrasound guidance, the probe was placed transversely between the iliac crest and costal margin. Ilioinguinal/ iliohypogastric nerves block group: received general anesthesia, with (0.2 mL/kg of 0.25% bupivacaine per side). The inferior portion of linear ultrasound transducer will be placed over the anterior superior iliac spine with the superior margin of the transducer pointed directly in an oblique plane toward the umbilicus. The superior margin of the ultrasound transducer was slowly rotated superiorly and inferiorly until the fascial plane between the internal oblique and transverse abdominis muscle is identified. Results The results of the study revealed that patients received IIN+IHN block had significantly lower pain scores at 8, 12, 16, 20, and 24 hrs after operation, delayed time for rescue analgesia and decreased total need of analgesic in the first 24hrs post-operative compared to patients who received TAP nerves block. Conclusion IIN+IHN block was effective in reducing postoperative pain scores for 4-6 hours, lowering total 24-h postoperative opioid and analgesic consumption and delaying the need for rescue analgesia after inguinal hernia repair under general anesthesia, compared to TAP nerves block. It will be more useful to study in high-risk hypertensive and cardiac patients and to correlate with plasma catecholamine levels, which reflect the stress response and it is necessary to evaluate postoperative pain on movement in farther studies.

Impact of automated alerts on discharge opioid overprescribing after general surgery

Abstract Purpose The objectives of this study were to identify the most performed surgical procedures associated with the highest rates of discharge opioid overprescribing and to implement an electronic health record (EHR) alert to reduce discharge opioid overprescribing. Methods This quality improvement, before-and-after study included patients undergoing one of the identified target procedures—laparoscopic cholecystectomy, unilateral open inguinal hernia repair, and laparoscopic appendectomy—at an academic medical center. The alert notified providers when the prescribed opioid quantity exceeded guideline recommendations. The preimplementation cohort included surgical encounters from January 2020 to December 2021. The EHR alert was implemented in May 2022 following provider education via email and in-person presentations. The postimplementation cohort included surgical encounters from May to August 2022. The primary outcome was the proportion of patients with a discharge opioid supply exceeding guideline recommendations (overprescribing). Results A total of 1,478 patients were included in the preimplementation cohort, and 141 patients were included in the postimplementation cohort. The proportion of patients with discharge opioid overprescribing decreased from 48% in the preimplementation cohort to 3% in the postimplementation cohort, with an unadjusted absolute reduction of 45% (95% confidence interval, 41% to 49%; P &amp;lt; 0.001) and an adjusted odds ratio of 0.03 (95% confidence interval, 0.01 to 0.08; P &amp;lt; 0.001). Among patients who received opioids, the mean (SD) opioid supply at discharge decreased from 92 (43) oral morphine milligram equivalents (MME) (before implementation) to 57 (20) MME (after implementation) (P &amp;lt; 0.001). The proportion of patients who received additional opioid prescriptions within 1 to 14 days following hospital discharge did not change (P = 0.76). Conclusion Implementation of an EHR alert along with provider education can reduce discharge opioid overprescribing following general surgery.

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.

Is mesh pore size in polypropylene meshes associated with the outcome in Lichtenstein inguinal hernia repair: a registry-based analysis of 22,141 patients

IntroductionExperimental data show that large-pored meshes reduce foreign body reaction, inflammation and scar bridging and thus improve mesh integration. However, clinical data on the effect of mesh porosity on the outcome of hernioplasty are limited. This study investigated the relation of pore size in polypropylene meshes to the outcome of Lichtenstein inguinal hernioplasty using data from the Herniamed registry.MethodsThis analysis of data from the Herniamed registry evaluated perioperative and 1-year follow-up outcomes in patients undergoing elective, primary, unilateral Lichtenstein inguinal hernia repair using polypropylene meshes. Patients operated with a non-polypropylene mesh or a polypropylene mesh with absorbable components were excluded. Polypropylene meshes with a pore size of 1.0 × 1.0 mm or less were defined as small-pored meshes, while a pore size of more than 1.0 × 1.0 mm was considered large-pored.Unadjusted analyses and multivariable analyses were performed to investigate the relation of pore size of polypropylene meshes, patient and surgical characteristics to the outcome parameters.ResultsData from 22,141 patients were analyzed, of which 6853 (31%) were operated on with a small-pore polypropylene mesh and 15,288 (69%) with a large-pore polypropylene mesh. No association of mesh pore size with intraoperative, general or postoperative complications, recurrence rate or pain requiring treatment was found at 1-year follow-up. A lower risk of complication-related reoperation tended to be associated with small-pore size (p = 0.086). Furthermore, small-pore mesh repair was associated with a lower risk of pain at rest and pain on exertion at 1-year follow-up.ConclusionThe present study could not demonstrate an advantage of large-pore polypropylene meshes for the outcome of Lichtenstein inguinal hernioplasty.

Bupivacaine vs. Ropivacaine with Dexmedetomidine for Unilateral Inguinal Hernia Repair: A Randomized Controlled Trial

Laparoscopic iliopubic tract repair for asymptomatic contralateral occult inguinal hernia.

Metachronous contralateral inguinal hernia (MCIH) may occur after unilateral inguinal hernia (IH) repair, potentially as a result of occult IH (OIH). Contralateral OIH can be checked for during laparoscopic transabdominal hernioplasty for the treatment of unilateral IH. This study aims to assess the efficacy of laparoscopic iliopubic tract repair (IPTR) in treating contralateral OIH to reduce MCIH. The medical charts of 3165 patients aged > 18years who underwent laparoscopic transabdominal hernioplasty for unilateral IH from January 2013 to December 2021 were retrospectively reviewed. The patients were categorized into two groups based on contralateral OIH presence: negative OIH (nOIH, 2657 patients) and OIH (508 patients). In cases of OIH, IPTR was performed, involving suturing of the iliopubic tract and transversalis fascia arch. MCIH was indirect in 26 and direct in 4 patients in the nOIH group, and was direct in 3 patients in the OIH group. The incidence of indirect MCIH was higher in the nOIH group than in the OIH (1.0% [n = 26/2657] vs. 0.0% [n = 0/508], p = 0.048). There was no difference in postoperative complication rates, pain scores, return to daily life, or duration of hospitalization between the nOIH and OIH groups. Laparoscopic IPTR for OIH treatment is an effective method for reducing the risk of indirect MCIH.
