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 < 0.001) and an adjusted odds ratio of 0.03 (95% confidence interval, 0.01 to 0.08; P < 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 < 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.

A retrospective noninferiority study of laparoscopic inguinal hernia repair feasibility for recently graduated surgeons in Thailand.

The feasibility of starting laparoscopic surgery among newly graduated surgeons lacking extensive experience in open approaches remains a topic of interest. We aimed to evaluate the safety and efficacy of laparoscopic inguinal hernia repair (LHR) compared to open inguinal hernia repair (OHR) in this population. This retrospective cohort study was conducted on inguinal hernia surgeries performed by a single recently graduated surgeon during the learning phase. Patient data were collected from July 2021 to November 2022 with a focus on demographics, intraoperative details, and 1-year postoperative outcomes. Noninferiority testing was employed with a predetermined margin of 15% to compare the complication rates, recurrence rates, and other secondary outcomes between LHR and OHR. The study cohort comprised 66 patients (OHR group, n = 45 and LHR group, n = 21). Patient characteristics were similar between groups. No significant differences were observed in the complication rates (OHR, 26.7% and LHR, 19.0%; p = 0.50) or recurrence rates (OHR, 2.2% and LHR, 4.8%; p = 0.54). The LHR group demonstrated noninferior outcomes compared with the OHR group in terms of complication, recurrence, readmission, and reoperation rates. Except for the operative time, secondary outcomes did not differ significantly between the groups. LHR is a feasible initiation for recently graduated surgeons, demonstrating noninferior outcomes compared with open repair. Therefore, the belief that one must master open surgery before beginning laparoscopy may be untrue.

Outcomes from Early Experience with Laparoscopic Inguinal Hernia Repair Versus Open Technique: Navigating the learning curve.

This study aimed to evaluate the outcomes of laparoscopic inguinal hernia repair (LIHR) regarding postoperative pain, recurrence rates, duration of hospital stay and other postoperative outcomes within the context of a tertiary care teaching hospital in South India, and the initial experience of laparoscopic repairs. The current consensus in the literature often suggests LIHR as superior to open inguinal hernia repair (OIHR). This single-centre, retrospective, observational study was conducted at the Jawaharlal Institute of Postgraduate Education and Research, Puducherry, India, from January 2011 to September 2020. All patients who underwent elective OIHR and LIHR were included. Data on the patients demographics, comorbidities, hernia type, mesh characteristics, surgery duration, hospital stay and immediate postoperative complications were collected and analysed. A total of 2,690 OIHR and 158 LIHR cases were identified. The demographic profiles, hospital stay and complication rates were similar in both groups. However, surgical site infection was present exclusively in the OIHR group (3.55% versus 0.0%; P <0.05). The timeline for returning to normal activities was statistically shorter for the LIHR group (6 versus 8 days; P <0.05). The most frequent immediate complication in the LIHR group was subcutaneous emphysema (6.54% versus 0.0%; P <0.05). Recurrence (9.23% versus 3.61%; P = 0.09) and chronic pain (41.53% versus 13.55%; P <0.05) were higher in the LIHR group. Lower recurrence and chronic pain rates were observed with OIHR in the initial experience with LIHR in the hospital. However, LIHR had significant advantages concerning faster patient recovery and lower rates of surgical site infections. While the results contribute an interesting deviation from the standard narrative, they should be interpreted within the context of a learning curve associated with the early experience of the research team with LIHR.

CPL-01, an investigational long-acting ropivacaine, demonstrates safety and efficacy in open inguinal hernia repair

BackgroundThere is an unmet medical need for effective nonopioid analgesics that can decrease pain while reducing systemic opioid use. CPL-01, an extended-release injectable formulation of ropivacaine, is designed to safely provide analgesia and reduce or eliminate opioid use in the postoperative period.MethodsSubjects undergoing open inguinal hernia with mesh were prospectively randomized to 1 of 3 doses of CPL-01 (10, 20, or 30 ml of 2% CPL-01, n = 14, 12, and 14, respectively), Naropin (150 mg, n = 40), or saline placebo (n = 13) infiltrated into the surgical site prior to closure. Pain and rescue medication usage was assessed, and Numeric Rating Scale (NRS) pain scores were adjusted for opioid usage using windowed worst observation carried forward (wWOCF) imputation. The primary efficacy endpoint was the mean area under the curve (AUC) of the NRS pain intensity scores with activity.ResultsNinety-three subjects were treated, and 91 subjects completed 72 h of post-operative monitoring. Subjects who received the highest dose of CPL-01 in Cohort 3 showed a clinically meaningful reduction in postoperative pain intensity scores, which was the lowest value for any treatment in all cohorts, showing a trend towards statistical significance as compared to the pooled placebo group (p = 0.08), and numerically better than the 40 subjects who received Naropin. Opioid use through 72 h in subjects who received CPL-01 in Cohort 3 was approximately half of that shown in the placebo and Naropin groups; approximately 2/3 of the CPL-01 subjects (9/14) required no opioids at all through the first 72 h after the operation. More CPL-01 subjects avoided severe pain and were ready for discharge earlier than other groups. CPL-01 was safe and well-tolerated, with no clinically meaningful safety signals, and showed predictable and consistent extended-release pharmacokinetics.ConclusionResults suggest that CPL-01 may be the first long-acting ropivacaine to address postoperative pain while reducing the need for opioids.

Open vs. robot-assisted preperitoneal inguinal hernia repair. Are they truly clinically different?

IntroductionInguinal hernia repair lacks a standard repair technique, with laparo-endoscopic and open preperitoneal methods showing similar outcomes. Despite higher costs, the popularity of robotic surgery is on the rise, driven by technological advantages. Controversies persist in comparing open repair techniques with the robotic approach, given contradictory results. The objective of this study was to compare postoperative outcomes, including complications, chronic pain, and recurrence, between open and robotic-assisted preperitoneal inguinal hernia repair.MethodsThis single-center retrospective study encompassed patients undergoing elective inguinal hernia repair in a specialized unit, employing both open preperitoneal and robotic-assisted laparoscopic approaches from September 2018 to May 2023. Comparative analysis of short- and long-term outcomes between these techniques was conducted. Additionally, multivariate logistic regression was employed to explore predictors of postoperative complications.ResultsA total of 308 patients met the inclusion criteria. 198 (64%) patients underwent surgery using an open preperitoneal approach and 110 (36%) using robot-assisted laparoscopy. Patients in the robot-assisted group were younger (P = 0.006) and had fewer comorbidities (P < 0.001). There were no differences between the groups in terms of postoperative complications (P = 0.133), chronic pain (P = 0.463) or recurrence (P = 0.192). Multivariate analysis identified ASA ≥ III (OR, 1.763; 95%CI, 1.068–3.994; P = 0.027) and inguinoscrotal hernias (OR, 2.371, 95%CI, 1.407–3.944; P = 0.001) as risk factors of postoperative complications.ConclusionsBoth open preperitoneal and robotic-assisted laparoscopic approaches show similar outcomes for complications, chronic pain, and recurrence when performed by experienced surgeons. The open preperitoneal approach, with its quicker operative time, may be advantageous for high-comorbidity cases. Treatment choice should consider patient factors, surgeon experience, and healthcare resources.

Trends in minimally invasive and open inguinal hernia repair: an analysis of ACGME general surgery case logs.

Groin hernia repair is one of the most commonly performed surgical procedures and is often performed by surgical interns and junior residents. While traditionally performed open, minimally invasive (MIS) groin hernia repair has become an increasingly popular approach. The purpose of this study was to determine the trends in MIS and open inguinal and femoral hernia repair in general surgery residency training over the past two decades. Accreditation Council for Graduate Medical Education (ACGME) national case log data of general surgery residents from 1999 through 2022 were reviewed. We collected means and standard deviations of open and MIS inguinal and femoral hernia repairs. Linear regression and ANOVA were used to identify trends in the average annual number of open and MIS hernia repairs logged by residents. Cases were distinguished between level of resident trainees: surgeon-chief (SC) and surgeon-junior (SJ). From July 1999 to June 2022, the average annual MIS inguinal and femoral hernia repairs logged by general surgery residents significantly increased, from 7.6 to 47.9 cases (p < 0.001), and the average annual open inguinal and femoral hernia repairs logged by general surgery residents significantly decreased, from 51.9 to 39.7 cases (p < 0.001). SJ resident results were consistent with this overall trend. For SC residents, the volume of both MIS and open hernia repairs significantly increased (p < 0.001). ACGME case log data indicates a trend of general surgery residents logging overall fewer numbers of open inguinal and femoral hernia repairs, and a larger proportion of open repairs by chief residents. This trend warrants attention and further study as it may represent a skill or knowledge gap with significant impact of surgical training.

Risk of conversion after intended total extraperitoneal hernia repair for inguinal hernia depends on type of previous abdominal surgery.

Risk of total extraperitoneal hernia repair (TEP) in patients with previous lower abdominal surgery (PLAS) is still debated. The present study was designed to assess the rate of conversion in TEP for inguinal hernia stratified by type of PLAS. Variables on patients undergoing TEP inguinal hernia repair at our center were prospectively collected between July 2012 and May 2018. Patients with PLAS were compared to patients without PLAS. Furthermore, the most frequent subtypes of PLAS were defined and TEP conversion rate was stratified according to type of PLAS. A total of 1589 patients with TEP inguinal hernia repair were identified including 152 (9.6%) patients with PLAS. Operative time was increased in patients with PLAS (70 vs. 60min, p < 0.001). Conversion from TEP to transabdominal preperitoneal patch plasty(TAPP) or Lichtenstein open inguinal hernia repair was eight-times more frequent after PLAS (8% vs. 1%, p < 0.001). Considering type of PLAS, open appendectomy was most frequently encountered, followed by multiple PLAS and surgery to the bladder and prostate (53%, 11% and 10%). After stratification for type of PLAS, conversions were most frequently found after previous surgery to the bladder or prostate and after multiple PLAS (conversion rate of 20% and 24%, p < 0.001). In contrast, conversion rate after open appendectomy was not increased. PLAS to the bladder and prostate is associated with TEP conversion. Selected patients might profit from a different operative approach for inguinal hernia repair.

Use of surgical procedure manager to standardise operation steps and monitor surgeon performance in open repair of inguinal hernia

AbstractObjectivesTo study the feasibility of using surgical procedure manager (SPM), a digital checklist platform, to standardise surgical steps of open hernia repair and monitor the operative performance.MethodologyA retrospective study on all open mesh repair of inguinal hernia under local anaesthesia from September 2019 to November 2021 at the Prince of Wales Hospital was performed. The operative outcomes of patients having operations with or without the use of SPM were compared. Procedures using SPM had operation steps shown as a digital checklist inside the theatre. The time used for each surgical step was recorded and analysed. The operative performance of the surgeons was analysed by observing the trend of the mean operation time over time.ResultsA total of 123 patients were recruited, of which 52 were using the SPM. The median age of patients was 75 (range 49–93) years. A decreasing trend in the mean operation time for dissection, mesh placement, wound closure and total operation time was observed in surgeries using SPM. There was no significant difference in the operation time, theatre time, total length of stay, blood loss and readmission rate between the SPM and non‐SPM groups. The proportion of basic surgical trainees as coached surgeons in the SPM group was significantly higher (SPM = 52% vs non‐SPM = 28%, P = .07).ConclusionsThe use of SPM did not significantly prolong the operation time and produce comparable operative outcomes in open hernia repair. It provided the additional advantage of standardising operation steps and monitoring the performance of surgical trainees during their training.

Comparison of laparoscopic and open inguinal–hernia repair in elderly patients: the experience of two comprehensive medical centers over 10 years

PurposeThe safety of laparoscopic inguinal–hernia repair must be carefully evaluated in elderly patients. Very little is known regarding the safety of the laparoscopic approach in elderly patients under surgical and medical co-management (SMC). Therefore, this study evaluated the safety of the laparoscopic approach in elderly patients, especially patients with multiple comorbidities under SMC.MethodsFrom January 2012 to December 2021, patients aged ≥ 65 years who underwent open or laparoscopic inguinal–hernia repair during hospitalization were consecutively enrolled. Postoperative outcomes included major and minor operation-related complications, and other adverse events. To reduce potential selection bias, propensity score matching was performed between open and laparoscopic groups based on patients’ demographics and comorbidities.ResultsA total of 447 elderly patients who underwent inguinal–hernia repair were enrolled, with 408 (91.3%) underwent open and 39 (8.7%) laparoscopic surgery. All postoperative outcomes were comparable between open and laparoscopic groups after 1:1 propensity score matching (all p > 0.05). Moreover, compared to the traditional care group (n = 360), a higher proportion of the SMC group (n = 87) was treated via the laparoscopic approach (18.4% vs. 6.4%, p = 0.00). In the laparoscopic approach subgroup (n = 39), patients in the SMC group (n = 16) were older with multiple comorbidities but were at higher risks of only minor operation-related complications, compared to those in the traditional care group.ConclusionsLaparoscopic inguinal–hernia repair surgery is safe for elderly patients, especially those with multiple comorbidities under SMC.

Impact Of Comorbidities On Outcomes And Healthcare Costs Of Open Inguinal Hernia Repair In Patients With Diabetes Mellitus.

Inguinal hernia management in patients with diabetes mellitus (DM) and comorbidities presents challenges due to potential impacts on wound healing and infection risk. This study evaluates the influence of additional comorbidities on outcomes following open inguinal hernia repair in DM patients. A retrospective cohort study was conducted at Craiova Emergency Clinical County Hospital from 2015 to 2020. Patients with documented DM undergoing hernia repair were categorized into two groups based on comorbidity status. Data on presentation mode, hernia type, comorbidities, hospitalization, operative details, postoperative outcomes, and costs were collected and analyzed statistically. Among 38 DM patients undergoing hernia repair, 16 were in Group A (DM alone) and 22 in Group B (DM with comorbidities). Group B patients were older (p = 0.0002) and more likely to present emergently (OR: 13.81, p=0.0148) with incarcerated (OR: 22.733, p=0.0339) or strangulated hernias (OR: 9.4545, p=0.0390). Group B had longer hospitalizations (p=0.00132) and higher hospitalization costs (p = 0.00262). DM patients with comorbidities are at higher risk for complex hernias and prolonged hospitalizations. Pulmonary fibrosis emerges as a significant comorbidity requiring specific perioperative strategies. Tailored preoperative assessments and care plans can optimize outcomes.

Comparative Analysis of Bilateral Open Inguinal Hernia Repair and Rives-Stoppa Repair: A Comprehensive Review.

Inguinal hernias present a significant healthcare burden globally, necessitating effective surgical management. This comprehensive review evaluates two primary surgical techniques for managing bilateral inguinal hernias: bilateral open inguinal hernia and Rives-Stoppa repair. This review aims to provide insights into optimal surgical approaches through a comparative analysis of these techniques, including examining advantages, disadvantages, outcomes, and factors influencing technique selection. Bilateral open inguinal hernia repair offers simplicity and familiarity, while Rives-Stoppa repair may provide advantages such as reduced recurrence rates and postoperative complications. The findings underscore the importance of considering patient-specific factors, surgeon expertise, and hospital resources when selecting the optimal approach. Further research is warranted to conduct long-term comparative studies and explore innovations in surgical techniques and materials, ultimately enhancing patient outcomes and advancing inguinal hernia repair practices.

Testicular Vascularization after Pediatric Inguinal Hernia Repair: A Systematic Review and Meta-Analysis.

The effect of pediatric inguinal hernia repair (IHR) on testicular vascularization remains unclear. Manipulating the spermatic cord during surgery may reduce blood flow due to edema and vasoconstriction. This can lead to testicular atrophy. The study aims to review current knowledge of testicular vascular impairment following IHR in children. A systematic literature search was conducted in PubMed/Medline, Embase, Cochrane Library, and Web of Science. Methodological quality was assessed using validated tools. Data were extracted, and a pooled data analysis was performed. Ten studies were included in the systematic review. Six of these studies were eligible for meta-analysis. This revealed a significant decrease in testicular vascularization during the short-term follow-up (1 day-1 week) after IHR using the open surgical approach. This decrease was not present after laparoscopic intervention. There was no more increased resistance in the vessels at long-term follow-up (1 month-6 months), suggesting that the impaired vascularity is only temporary. There seems to be a short-term transient vascular impairment of the testis after open IHR in children. This might be of clinical relevance to prefer the laparoscopic approach for IHR in children, even though the open approach is the gold standard, in contrast to adult IHR. The impact on testicular function and sperm quality later in life remains unclear. Comparative studies of both techniques are needed to determine if there is a significant difference in testicular vascularity. Long-term studies are necessary to assess the impact of transiently reduced vascularity on sperm quality and fertility later in life.

Identification of the ilioinguinal and iliohypogastric nerves during open inguinal hernia repair: a nationwide register-based study

BackgroundChronic pain remains prevalent after open inguinal hernia repair and nerve-handling strategies are debated. Some guidelines suggest sparing nerves that are encountered; however, the nerve identification rates are unclear. This study aimed to investigate the nerve identification rates in a register-based nationwide cohort.MethodsThis study was reported according to the RECORD guideline and used prospective, routinely collected data from the Danish Hernia Database, which was linked with the National Patient Registry. We included patients ≥ 18 years old, undergoing Lichtenstein hernia repair with information on nerve handling of the iliohypogastric and ilioinguinal nerves.ResultsWe included 30,911 open hernia repairs performed between 2012 and 2022. The ilioinguinal nerve was identified in 73% of the repairs and the iliohypogastric nerve in 66% of repairs. Both nerves were spared in more than 94% of cases where they were identified. Female patient sex, emergency and recurrence surgery, general anesthesia, medial and saddle hernias, and large defect size all result in lower nerve identification rates for both nerves.ConclusionThe Ilioinguinal nerve was recognized in 73% of cases, while the iliohypogastric nerve was recognized in 66% with almost all identified nerves being spared during surgery. Several pre- and intraoperative factors influenced identification rates of the ilioinguinal and iliohypogastric nerve.

Comparative evaluation of pre-emptive analgesic efficacy of Posterior Transversus Abdominis Plane block with Fascia Transversalis Plane Block in adult patients undergoing unilateral inguinal hernia repair: A prospective, randomized, single-blind, two-arm parallel study.

Abdominal wall blocks, in conjunction with multimodal analgesia, have demonstrated efficacy in providing post-operative analgesia, reducing opioid requirements in patients undergoing inguinal hernia repair. The inguinal region is primarily innervated by the ilioinguinal nerve (IIN) and iliohypogastric nerve (IIH). Posterior transverse abdominis plane block (pTAP) and fascia transversalis plane block (TFP) have been observed to reliably block IIN and IIH. We hypothesized that posterior TAP block (pTAP) owing to its potential paravertebral spread will provide better post-operative analgesia than TFP block in patients undergoing unilateral open inguinal hernia repair. This prospective, randomized, single-blind, two-arm parallel study was conducted over a duration of one year for which sixty patients undergoing unilateral open inguinal hernia repair under spinal anesthesia were enrolled. They were equally and randomly assigned to receive either preoperative pTAP block or TFP block. The primary aim of the study was to compare median static and dynamic NRS scores during a 24-hour period, with the secondary aim to compare the number of patients who required rescue analgesics in each group. All enrolled patients completed the study. Results showed no statistically significant difference in median static NRS scores between Group pTAP and Group TFP at the designated time of observation during the 24-hour period [1.2 (0.4-1.60 vs. 1 (0.6-1)]. Group pTAP reported a higher median dynamic NRS scores during the 24-hour period [2.6 (1.2-3) v/s 2 (1.6-2.4); P < 0.035], although this difference was clinically insignificant. The mean time to request for the first rescue analgesia was comparable (11.7 h v/s 12 h; P = 0.99). In all the patients of both groups, loss of pinprick and cold touch sensation was observed at T10, T12, and L1 dermatomal levels. However, sensory assessment at T6 and T8 levels showed variability between the two groups (P > 0.05). In conjunction with background analgesia and the use of dexamethasone as an adjuvant, both blocks (pTAP and TFP) were observed to be equally effective for post-operative pain relief with similar patient satisfaction scores.

Connecting Coding and Policy: Inguinal Hernias in Children

The June 2023 American Academy of Pediatrics clinical report, “Assessment and Management of Inguinal Hernias in Children” (https://doi.org/10.1542/peds.2023-062510), notes that inguinal hernia repair is one of the most commonly performed surgical procedures in children. In addition to the procedural considerations included in the clinical report, it is important that physicians who repair inguinal hernias and their coding and billing staff know the correct codes for reporting these procedures. This article reviews the following topics: Evaluation and management with decision for surgery Diagnosis codes for inguinal hernia Laparoscopic inguinal hernia repair Open inguinal hernia repair

Higher rate of chronic pain in young men after open mesh vs nonmesh repair of elective primary unilateral indirect inguinal hernia: A nationwide questionnaire study

PurposeYoung age is a risk factor for chronic pain after inguinal hernia repair, but the role of the mesh in young patients is uncertain. The aim of this study was to assess chronic pain after open mesh versus non-mesh repair of indirect inguinal hernia in young men. Materials and methodsValidated questionnaires were sent to men aged 18–29 years at the time of an elective primary unilateral open repair of an indirect inguinal hernia between 1998 and 2015. Patients were identified in the Danish Hernia Database. Non-mesh repairs were matched 1:3 with mesh repairs (Lichtenstein) on age and follow-up time. The primary outcome was the proportion of patients with chronic pain evaluated with the Activity assessment scale. Secondary outcomes included other pain measures and sexual impairment. ResultsIn total, 661 patients were included in this study (77% mesh and 23% non-mesh) with a median follow-up of 14.8 years (range 2.3–20.0) in the mesh group and 15.9 years (range 3.6–20.0) in the non-mesh group. For the primary outcome, 12% of patients in the mesh group compared with 6% in the non-mesh group had chronic pain (p=0.03). Patients in the mesh group had higher odds of chronic pain in adjusted analysis (OR=2.30 [95% confidence interval=1.11–4.77]). More patients in the mesh group had pain during sexual activity (p=0.01), but there were no differences for most of the remaining secondary outcomes. ConclusionYoung men had a higher rate of chronic pain after open mesh compared with non-mesh repair for indirect inguinal hernia, but results should be interpreted with caution.

Enhancing Pain Management for Open Inguinal Hernia Repair With a Novel Long-Acting Bupivacaine Drug Device (Xaracoll®) in Multimodal Pain Control: A Quality Improvement Initiative to Reduce Post-Operative Opioid Prescribing.

Background Xaracoll® is a Food and Drug Administration (FDA) approved Type 1 Bovine collagen-based bupivacaine hydrochloride (HCl) implant developed to provide postoperative pain management for up to 24 hours after open inguinal hernia repair in adults. This retrospective review examinedthe efficacy of Xaracoll® in the management of postoperative pain compared to injectable Bupivacaine. Methods This retrospective study examines 54 patients who underwent unilateral open inguinal hernia repair by a single surgeon over three years. The control group consisted of 36 patients who received injectable Bupivacaine as the local anesthetic. Eighteen patients received the Xaracoll® drug device intra-operatively following the FDA-approved manufacturer's guidelines. Intra-operative analgesics administered and quantified by oral morphine equivalents (OME), opioid administration for pain control postoperatively, opioid prescriptions upon discharge, postoperative pain scores, and turnaround time (TAT) were compared. Results The use of Xaracoll® in inguinal hernia repair is associated with a decrease in the rate of opioid administration in the post-anesthesia care unit (PACU) (22.2% vs. 52.8%; p = 0.043). In addition, patients requiring opioids in the outpatient setting needed significantly less OME in the Xaracoll® group compared to the control group (52.50 vs. 136.15; p < .001). Conclusion This study demonstrates compelling evidence that Xaracoll® is a useful analgesia adjuvant for inguinal hernia repair, significantly reducing the need for opioids in the PACU and decreasing doses of opioid medications upon discharge.Xaracoll® is effective in minimizing postoperative pain and opioid medication dosages upon discharge as part of a multimodal approach to pain and improving patient experience. Further research is warranted to evaluate Xaracoll®'s role in pain control in the PACU and on discharge.
