Carolinas Comfort Scale as a Measure of Hernia Repair Quality of Life: A Reappraisal Utilizing 3788 International Patients

Quality of life and abdominal wall functionality after abdominal wall reconstruction: A prospective single center follow-up study

BACKGROUND

Fascial breakdown with the occurrence of an incisional hernia (IH) is an important and challenging complication of any laparotomy. For a long time, the success of the abdominal wall reconstruction (AWR) was measured only from the surgeon's perspective by defining outcome measures such as wound morbidity and recurrence. The understanding that complete recovery is difficult to assess without considering patients has shifted the paradigm of optimal outcomes to Patient Reported Outcome Measures (PROMS) and Quality of Life (QoL), which are pivotal to evaluate the success and efficacy of AWR.

METHODS

We conducted a prospective follow-up study of 91 patients undergoing mesh-augmented abdominal wall reconstruction for primary or recurrent incisional hernia between January 2021 and December 2023. Demographic data, comorbidities, and hernia characteristics were recorded. All patients were evaluated preoperatively by a native abdomino-pelvic CT scan to assess the characteristics of hernia (length, width, surface, and volume of the incisional hernia sac and of peritoneal cavity), the presence of mesh (if previously inserted), and abdominal wall muscles status. All intervention were performed by the same surgical team according to the techniques described by Rives - Stoppa (RS), Ramirez (ACS), and Novitsky (PCS). Abdominal wall function was assessed using trunk raising (TR) and double leg lowering (DLL) measurements performed preoperatively, 1 month, 6 months, and 1 year postoperatively. At the same time, pre- and post-operative quality of life was analysed using the EQ-5D score.

RESULTS

Mean age of 59.42 ± 12.28 years and a male/female ratio of 35/56 were recorded, most of them being obese. There were 36 (42%) patients with defects larger than 10 cm. The distribution of the type of surgical intervention was: RS 35 patients, ACS 13 patients, and PCS 43 patients. The mean value of combined score for the preoperative abdominal wall functionality was 4.41 ± 1.67 (2-8) while the mean value of preoperative EQ-5D index was 0.652 ± 0.026 (-0.32-1.00). QoL was poor and very poor for 48% (44) of the patients who recorded index values less than 0.56 (50% percentile). Preoperative EQ-5D index was highly correlated with Combined AWF score (r = 0.620; p < 0.0001) and the correlation was specific (AUC = 0.799; p < 0.0001; asymptotic 95%CI = 0.711-0.923). At 12 months, the AWF score increased to 8.13 ± 2.58 (1-10) and the QoL total score to 0.979 ± 0.007 (0.71-1). Good and very good total scores for QoL were recorded for 47 patients (84%) compared to 33 (36%) in the preoperative evaluation (χ2 with Yates continuity correction for two degrees of liberty = 46.04; p < 0.00001).

CONCLUSION

Our results suggest that patients can expect to see a significant overall improvement in all five components of QoL measured with the help of Eq. 5D questionnaire. This improvement is dependent by hernia size, and some individual patient's factors (diabetes, cardiovascular diseases, and age over 60 years).

Higher rates of recurrence and worse quality of life in obese patients undergoing inguinal hernia repair

PURPOSE

Prior investigations regarding the effect of obesity on inguinal hernia repair have been mixed. The aim of our study was to retrospectively compare perioperative outcomes, recurrence rate, and quality of life between obese and non-obese patients undergoing inguinal hernia repair.

METHODS

Patients who underwent inguinal hernia repair by any approach at a single institution were identified from a prospectively maintained quality database. Patients with a body mass index (BMI) greater than or equal to 30 kg/m2 were considered obese. Quality of life was measured with the Surgical Outcomes Measurement System (SOMS) and Carolinas Comfort Scale (CSS) surveys. Differences between obese and non-obese patients were assessed using independent samples t-tests, Wilcoxon rank-sum, and chi-square tests.

RESULTS

Between 2010 and 2021, a total of 5575 patients underwent inguinal hernia repair. Fifteen percent of patients were identified as obese (835 patients, mean BMI 33.2 ± 3.3 kg/m2). A significantly higher percentage of obese patients were diabetic, and operative time and estimated blood loss were higher in the obese group (all p < 0.001). Rates of hernia recurrence in obese patients was significantly more likely than in non-obese patients (4.2% vs 2.0%, p < 0.001). Up to 2 years postoperatively, a greater percentage of obese patients reported worse quality of life on the SOMS and more bothersome symptoms on the CCS.

CONCLUSIONS

Inguinal hernia repair in obese patients is a more technically challenging operation. Long-term follow-up revealed a greater risk of hernia recurrence and worse quality of life up to 2 years postoperatively in this patient population.

Validation of the carolinas comfort scale (CCS) in Brazil: a hernia-specific quality of life questionnaire

INTRODUCTION

Ventral hernia surgery (VHS) has the intent to promote a better quality of life (QoL). VHS results were evaluated by recurrence incidence in the past, however the concept of Patient-Reported Outcomes Measures has changed this scenario. SF-36 is a generic questionnaire with some limitations on the hernioplasty postoperative evaluation. Disease-specific surveys such Hernia-Related Quality of Life Survey (HerQLes) and Carolinas Comfort Scale (CCS) were developed to improve specificity. The aim of this study was to validate a Brazilian version of the CCS as a QoL questionnaire for patients undergoing VHS in Brazil.

MATERIALS AND METHODS

The study consists of a retrospective cohort that reviewed the medical records of patients who underwent ventral hernia surgery for incisional hernias in the Hospital de Clínicas de Porto Alegre between January 2019 to December 2020. Participants answered both the HerQles questionnaire and the CCS, then we compared the patients' scores between scales. In-personal evaluations or surveys applied by telemedicine were performed. Intraclass correlation coefficient was utilized to assess the consistency of the agreement between the HerQLes and CCS scales.

RESULTS

A sample of 80 patients were evaluated. Most were male (70%), mean age 61.11 years and BMI 28.4. The most common comorbidity was systemic arterial hypertension, one third were smokers and 77.5% of cases were ASA 2. The average HerQLes score was 30.40 and the CCS was 15.46 (SD: 21.81), with an intraclass coefficient of 0.68.

CONCLUSION

This study suggests that CCS is a good and robust tool for assessing ventral hernia. Tools to measure QoL are increasingly used in the literature, as QoL seems to be important data to assess surgical success, since it shows the perception of the patient about the results of their surgery. Further studies with larger sample sizes should be performed to confirm our findings.

A comparison of patient-reported outcomes in patients undergoing abdominal wall repair with either synthetic or biosynthetic mesh: a pilot study

PURPOSE

Repair of midline ventral incisional hernias (VIHR) requires mesh reinforcement. Mesh types can be categorised into synthetic, biosynthetic, or biological. There is a lack of evidence to support one type of mesh over another. The aim of this pilot study was to compare mesh sensation in patients having undergone elective open repair with synthetic or biosynthetic mesh.

METHODS

Four years of prospectively collected data were retrospectively reviewed on 40 patients who had undergone VIHR, using either biosynthetic or synthetic mesh placed in the retromuscular plane. The decision on type of mesh used was governed by patient characteristics. Patients were invited to complete the Carolinas Comfort Scale (CCS) questionnaire, the higher the score indicating a poorer quality of life. The maximum length of follow-up was 36 months.

RESULTS

Twenty patients received permanent synthetic and 20 biosynthetic mesh. There was no clinical evidence of hernia recurrence in either group in the short to medium term. Overall, 97% (39/40) patients reported an average of either no or mild symptoms (mean CCS score 17.9 of 115). Patients with a biosynthetic repair had a significant lower CCS at ≥ 18 months (p < 0.05).

CONCLUSION

After VIHR, patients have low CCS scores, indicating good quality of life outcomes, in the short to medium term irrespective of the mesh used. However, biosynthetic mesh had lower CCS scores in the medium term. This may help surgeons and patients make better informed decisions about which mesh to use in their individual circumstances.

Elective complex ventral hernia repair in contaminated fields: A propensity score-matched analysis of long-term quality of life and outcomes between different prostheses

BACKGROUND

Randomized studies have endorsed nonabsorbable prosthetics for contaminated ventral hernia surgery, yet the broader applicability and impact on patient-reported outcomes are still questioned. Here, we evaluated the long-term outcomes of elective contaminated ventral hernia repairs (based on Centers of Disease Control and Prevention [CDC] wound classification) using real-world data from a multicenter US cohort, focusing on quality of life and postoperative pain.

METHODS

The Abdominal Core Health Quality Collaborative database was queried for patients undergoing elective contaminated (CDC class II-IV) ventral hernia repair (2013-2023). After propensity matching, we compared long-term differences in patient-reported quality of life and pain scores (by HerQLes and PROMIS questionnaires) among those who underwent repair with nonabsorbable, absorbable synthetic, and biologic mesh.

RESULTS

A total of 1,073 patients were included, of whom 920 (86%), 56 (5%), and 97 (9%) underwent repair with nonabsorbable, absorbable synthetic, and biologic mesh, respectively. Among them, the median age was 62 years (interquartile range [IQR] 53-70), and 523 (49%) were male. The median length and width of the defect were 20 cm (IQR 12-25) and 13 cm (IQR 8-16), respectively. A transversus abdominis release was performed in 716 patients (67% of all cases). In most cases, the mesh was positioned in the retro-rectus (85%) and/or the preperitoneal space (45%). Before and after propensity matching (n = 185), the change from baseline in HerQLes and PROMIS scores at 6 months and at 1, 3, 5, and 6 years was comparable between different types of mesh. Lastly, there were no differences in readmission, surgical site infection, or surgical site occurrence at 30 days. Recurrence at 1 year was also comparable among groups.

CONCLUSION

In the long term, there were no differences in quality of life or pain scores with nonabsorbable, absorbable synthetic, or biologic mesh for elective ventral hernia repair in contaminated fields.

The DySLOH Study: Comparative Evaluation of the Results between the ProFlor and Lichtenstein Techniques for Open Inguinal Hernia Repair-A Randomized Controlled Trial

Background: The Lichtenstein open anterior approach with static flat meshes, the most popular inguinal hernia repair technique, has raised concerns regarding mesh fixation, defect patency, and poor quality biological response. To address these issues, the 3D dynamic ProFlor scaffold promoting a fixation-free hernia defect obliteration has been developed as an alternative. Methods: The results of open inguinal hernia repair with the ProFlor approach compared with those of the Lichtenstein repair were evaluated. Results: In a time frame of 24 months, two cohorts of patients were enrolled, 95 in the ProFlor group and 93 in the Lichtenstein group. ProFlor demonstrated superior outcomes compared to the Lichtenstein technique, with shorter procedure times, decreased intraoperative complications, and lower rates of postoperative complications. Additionally, ProFlor provided enhanced postoperative pain relief, a faster return to daily activities, and no long-term discomfort. No chronic pain was reported in the ProFlor group and 11.8% reported chronic pain in the Lichtenstein group. Conclusions: The results highlight the need to reevaluate the conventional Lichtenstein approach and align it with recent scientific progress. Further consideration of the evolving understanding of inguinal pathophysiology and groin protrusion genesis is crucial for advancing surgical techniques.

The outcomes of component separation technique versus no component separation technique in the repair of large ventral hernias and impact on quality of life: a multicenter retrospective cohort study

Purpose

This study aimed to compare the results of patients who underwent anterior component separation techniques (ACST) and those who did not undergo component separation techniques (non-CST) in complicated ventral hernia repairs (VHRs) and to investigate the effect of these techniques on quality of life (QoL).

Methods

A total of 105 patients who were operated for large ventral hernias were retrospectively analyzed. The patients were divided into the ACST group (n = 48) and the non-CST group (n = 57). Demographic, intraoperative, and postoperative data were recorded. Postoperative follow-up was conducted at 2 and 4 weeks, and 6, 12, and 24 months. The primary and secondary outcomes and QoL were measured.

Results

The female ratio was higher in both groups (P = 0.512). There was no significant difference between age and body mass index between the groups (P = 0.705 and P = 0.803). The mean defect size and mesh size were similar between the groups (P = 0.775 and P = 0.245). The mean operation duration and amount of blood loss were similar between the groups (P = 0.801 and P = 0.142). There was no statistically significant difference in the median visual analog scale scores between the groups (P = 0.551). During follow-up, only 3 patients (6.3%) in the ACST group and 4 patients (7.0%) in the non-CST group had recurrence. There was no significant difference in the short- and long-term QoL between the groups.

Conclusion

The ACST is a feasible surgical option for patients with complicated VHRs. In addition, by improving QoL, the recurrence rate is similar to patients undergoing standard VHR.

Initial experience of minimally invasive mesh explantation for inguinodynia

BACKGROUND

Chronic pain after minimally invasive inguinal hernia repair with mesh can have debilitating effects on quality of life (QOL), limiting daily activities and ability to work. Many medical and surgical options for treatment have been proposed, however there is no consensus on the role of mesh explantation in the management of these patients.

METHODS

We performed a retrospective review of all patients who underwent groin mesh removal by robotic or laparoscopic approach from July 2012 to July 2023 at our institution. Patients were interviewed post-operatively to determine their overall pain scores and QOL was assessed using the Carolinas Comfort Scale (CCS) Questionnaire. Patient characteristics, operative times, pre-operative imaging techniques and analgesia use was also recorded.

RESULTS

Twenty-two patients underwent groin mesh removal for chronic pain, including 12 robotic and 10 laparoscopic operations. The mean pre-operative pain score in all patients was 7.6/10 compared to 4.0/10 post-operatively. The mean post-operative CCS score was 24, indicating moderate discomfort. Four patients demonstrated CCS scores <11 indicating no discomfort and no patients demonstrated CCS scores >90, indicating severe debilitating discomfort. The majority of patients had a reduction or total cessation of analgesia intake post-operatively.

CONCLUSION

Both laparoscopic and robotic mesh explantation for treatment of chronic pain post-inguinal hernia repair is safe and effective in achieving a reduction in pain and reducing the need for long-term analgesia.

Cross-cultural adaptation and validation of Carolinas Comfort Scale to Brazilian Portuguese for inguinal hernia

PURPOSE

Inguinal hernias are highly prevalent worldwide and its surgical repair is one of the most common procedures in general surgery. The broad use of mesh has decreased the recurrence rates of inguinal hernia to acceptable levels, thus centering the attention on Quality of Life as a pivotal postoperative outcome. Carolinas Comfort Scale is a well-studied questionnaire designed to identify Quality of Life changes following hernia repair with mesh techniques. The aim of this study is to validate the CCS in Brazilian Portuguese for inguinal hernias.

METHODS

The original CCS was translated into Brazilian Portuguese according to cross-cultural adaptation guidelines. We conducted a cross-sectional study in individuals aged 18 and above who had undergone inguinal laparo-endoscopic hernia repair for at least 6 months prior, between January 2019 and August 2022, at a Brazilian tertiary hospital. Participants answered an online survey containing the Brazilian CCS and the generic Patient-Reported Outcome Measure (PROM) Short-Form Health 36 (SF-36). Participants answered the same questionnaires in the follow-up after at least three weeks, with an additional question about satisfaction with surgery results.

RESULTS

The survey was completed by 115 patients, of whom 78 (67%) responded to the follow-up questionnaire after 3 to 10 weeks. CCS showed excellent internal consistency, with Cronbach's α of 0.94. Intraclass correlation coefficient ranged from 0.60 to 0.82 in the test-retest analysis. Compared to SF-36, a strong correlation was observed in the physical functioning dimension, and a moderate correlation was found in role-physical and bodily pain (Pearson's Coefficient Correlation = 0.502, 0.338 and 0.332 respectively), for construct analysis. The mean CCS score was significantly lower (p < 0.001) among satisfied patients compared to the unsatisfied ones.

CONCLUSION

The Brazilian version of CCS is a valid and reliable method to assess long-term quality of life after inguinal laparo-endoscopic hernia repair.

Comprehensive retrospective analysis of the European hernia Society quality of life in patients undergoing abdominal wall reconstruction

INTRODUCTION

This study aimed to analyze the European Hernia Society Quality of Life (EHS-QoL) in abdominal wall reconstruction by comparing preoperative scores with those at 1 and 2 postoperative years.

METHODS

Data from 105 patients with complex incisional hernias were collected preoperatively and at 1 and 2 years postoperatively. Statistical analyses included three ART ANOVA models to compare scores among the three time points and within each time point's items.

RESULTS

The EHS score significantly decreased from preoperative (Mdn ​= ​57) to 1 year (Mdn ​= ​10.5) and 2 years postoperative (Mdn ​= ​8). The most significant changes occurred between preoperative and 1-year measurements, particularly in pain levels during activities and limitations in heavy labor and activities outside the home.

CONCLUSION

Patients' quality of life notably improved at 1 year post-surgery, with some reaching near-maximum levels, and this improvement was generally sustained or increased at 2 years post-surgery.

Outcomes of Robotic Transabdominal Retromuscular Repair: 3-Year Follow-up

Background

Our study addresses the gap in ventral hernia repair literature, regarding the long-term effectiveness of robotic transabdominal retrorectus umbilical prosthetic repair (r-TARUP) for primary and incisional ventral hernias. This study aimed to report the 3-year recurrence rates and overall patient outcomes including quality of life.

Method

A retrospective review of prospective collected data analyzed 101 elective r-TARUP patients from August 2018 to January 2022. Data collected included demographics, hernia sizes, mesh types, postoperative outcomes and the European Hernia Society Quality of Life questionnaire (EuraHS-QoL) before and after surgery.

Results

The average age of the group of patients was 53, having a mean body mass index (BMI) of 32 kg/m, with 54% incisional and 46% primary hernias, with mean length and width of 4.4 cm and 6.1 cm, utilizing synthetic 58% and bioabsorbable 42% mesh types. The majority were classified as Centers of Disease Control and Prevention (CDC) class I wounds. Postoperative complications included seroma (2%), hematoma (3%), which required surgical intervention, with no significant correlation to mesh type. A strong positive correlation was found between Transversus Abdominis Release (TAR) and increased length of hospital stay (correlation coefficient: 0.731, p < 0.001). Preoperative quality of life assessments demonstrated statistically significant improvements when compared to postoperative assessments at 3 years, with a mean (±SD) of 61.61 ± 5.29 vs. 13.84 ± 2.6 (p < 0.001). Mean follow up of 34.4 months with no hernia recurrence at 1 year and 3 recurrence at the 2-3 years follow up (3.2%).

Conclusion

The r-TARUP technique has proven to be safe and effective for repairing primary and incisional ventral hernias, with a low recurrence rate during this follow up period with a noticeable improvement in quality of life (QoL).

Patient-reported outcomes in inguinal hernia surgery-Results from the GENESIS study: A multinational multicenter study

BACKGROUND

Chronic groin pain following inguinal hernia repair can be troublesome. The current literature is limited, especially from Asia and Africa. We aimed to evaluate patient-reported outcomes using the Carolinas Comfort Scale (CCS) following inguinal hernia repair at an international level, especially to include patients from Asia and Africa.

METHODS

An international cohort of surgeons was invited to collaborate and collect data of consecutive adult patients who underwent inguinal hernia repair. The data were collected to allow at least 2 years of follow-up. A total score for CCS was calculated and compared for the following groups-patient age <30 years versus (vs.) > 30 years; open versus laparoscopic repair, emergency versus elective surgery, and unilateral versus bilateral hernia repair. The CCS scores between Asia, Africa, and Europe were also compared.

RESULTS

The mean total CCS score of patients operated in Asia (n = 891), Europe (n = 853), and Africa (n = 157) were 7.32, 14.6, and 19.79, respectively. The total CCS score was significantly higher following open repair, emergency repair, and unilateral repair, with surgical site infections (SSI) and recurrence. In the subgroup analysis, the patients who underwent elective open repair in Europe had higher CCS scores than those in Asia.

CONCLUSION

About 15% of patients had a CCS score of more than 25 after a minimum follow-up of 2 years. The factors that influence CCS scores are indication, approach, complications, and geographic location.

A Scoping Review of Quality-of-Life Assessments Employed in Abdominal Wall Reconstruction

INTRODUCTION

Surgeons use several quality-of-life instruments to track outcomes following abdominal wall reconstruction (AWR); however, there is no universally agreed upon instrument. We review the instruments used in AWR and report their utilization trends within the literature.

METHODS

This scoping review was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis extension for Scoping Reviews guidelines using the PubMed, Embase, Web of Science, ClinicalTrials.gov, and Cochrane databases. All published articles in the English language that employed a quality-of-life assessment for abdominal wall hernia repair were included. Studies which focused solely on aesthetic abdominoplasty, autologous breast reconstruction, rectus diastasis, pediatric patients, inguinal hernia, or femoral hernias were excluded.

RESULTS

Six hernia-specific tools and six generic health tools were identified. The Hernia-Related Quality-of-Life Survey and Carolinas Comfort Scale are the most common hernia-specific tools, while the Short-Form 36 (SF-36) is the most common generic health tool. Notably, the SF-36 is also the most widely used tool for AWR outcomes overall. Each tool captures a unique set of patient outcomes which ranges from abdominal wall functionality to mental health.

CONCLUSIONS

The outcomes of AWR have been widely studied with several different assessments proposed and used over the past few decades. These instruments allow for patient assessment of pain, quality of life, functional status, and mental health. Commonly used tools include the Hernia-Related Quality-of-Life Survey, Carolinas Comfort Scale, and SF-36. Due to the large heterogeneity of available instruments, future work may seek to determine or develop a standardized instrument for characterizing AWR outcomes.

The INCH-trial: a multicenter randomized controlled trial comparing short- and long-term outcomes of open and laparoscopic surgery for incisional hernia repair

BACKGROUND

Laparoscopic incisional hernia repair is increasingly performed worldwide and expected to be superior to conventional open repair regarding hospital stay and quality of life (QoL). The INCisional Hernia-Trial was designed to test this hypothesis.

METHODS

A multicenter parallel randomized controlled open-label trial with a superiority design was conducted in six hospitals in the Netherlands. Patients with primary or recurrent incisional hernias were randomized by computer-guided block-randomization to undergo either conventional open or laparoscopic repair. Primary endpoint was postoperative length of hospital stay in days. Secondary endpoints included QoL, complications, and recurrences. Patients were followed up for at least 5 years.

RESULTS

Hundred-and-two patients were recruited and randomized. In total, 88 patients underwent surgery and were included in the intention-to-treat analysis (44 in the open group, 44 in the laparoscopic group). Mean age was 59.5 years, gender division was equal, and BMI was 28.8 kg/m. The trial was concluded early for futility after an unplanned interim analysis, which showed that the hypothesis needed to be rejected. There was no difference in primary outcome: length of hospital stay was 3 (range 1-36) days in the open group and 3 (range 1-12) days in the laparoscopic group (p = 0.481). There were no significant between-group differences in QoL questionnaires on the short and long term. Satisfaction was impaired in the open group. Overall recurrence rate was 19%, of which 16% in the open and 23% in the laparoscopic group (p = 0.25) at a mean follow-up of 6.6 years.

CONCLUSIONS

In a randomized controlled trial, short- and long-term outcomes after laparoscopic incisional hernia repair were not superior to open surgery. The persisting high recurrence rates, reduced QoL, and suboptimal satisfaction warrant the need for patient's expectation management in the preoperative process and individualized surgical management.

Prospective, international analysis of quality of life outcomes in recurrent versus primary ventral hernia repairs

BACKGROUND

Quality of life (QOL) has become a key outcome measure following ventral hernia repair (VHR), but recurrent and primary VHR have not been compared in this context previously.

METHODS

The International Hernia Mesh Registry (2008-2019) was used to identify patients with QOL data scored by the Carolinas Comfort Scale preoperatively and postoperatively at 1 year.

RESULTS

Repairs were performed in 227 recurrent and 1,122 primary VHs. Recurrent patients had a higher BMI, larger defects, and were more likely to have preoperative pain, but other comorbidities were equal. Recurrence rates at 1 year were equivalent. Recurrent patients had a greater improvement in pain (-6.3 ± 10.2 vs -4.3 ± 8.3,p = 0.002) and movement limitation (-5.5 ± 10.0 vs -3.2 ± 7.2,p < 0.001) compared to primary patients, but they had increased postoperative mesh sensation (4.6 ± 7.7 vs 2.7 ± 5.5,p < 0.001).

CONCLUSIONS

Recurrent VHRs led to improved pain and movement limitation, but increased mesh sensation. These findings may be useful for preoperative counseling in the elective setting.

The Role of Quality Improvement Projects in a Complex Abdominal Wall Service

Background Complex abdominal wall hernias have proven challenging to manage, and such patients often require abdominal wall reconstruction (AWR). However, in the context of a socialist healthcare service, which is required to provide equal and fair healthcare access to all, the heavy resource burden and non-life-threatening nature of complex abdominal wall hernias mean that this patient group may not be prioritised. In this paper, we outline the significant quality of life (QoL) burden on patients requiring AWR and the importance of quality improvement projects (QIPs) in establishing and streamlining their care as a robust, transferable model across centres. Methodology We undertook the creation of a regional AWR multidisciplinary team meeting and referral proforma, establishing a joint clinic between the Plastics and General Surgery teams and registering a standard operating procedure for the use of progressive pneumoperitoneum in a subset of AWR patients. We collected qualitative data using questionnaires sent out to clinicians and patients as well as used recognised outcome scales (pre- and post-operative European Hernia Society Quality of Life score, otherwise known as EuraHS-QoL score, and post-operative Carolinas Comfort Scale score) to assess responses to QIPs. Results Both clinicians and patients reported positive feelings towards the implemented changes, and scores following progressive pneumoperitoneum showed significant improvement. Conclusions Therefore, we propose that QIPs have a significant role in the establishment and streamlining of services for patients requiring AWR. Through the repeated use of QIPs, a robust, transferable model could be produced, which could then be shared with other regional specialist centres nationwide. As such, effective care could be offered equally to AWR patients for improved outcomes and reduced strain on healthcare resources.

Surgical and Patient-Reported Outcomes of Open Perforator-Preserving Anterior Component Separation for Ventral Hernia Repair

BACKGROUND

 Abdominal wall reconstruction is challenging for surgeons and may be life altering for patients. There are scant high-quality studies on patient-reported outcomes following abdominal wall reconstruction. We assess long-term surgical and patient-reported outcomes of perforator-preserving open anterior component separation (OPP-ACS) following large ventral hernia repair.

METHODS

 A retrospective review of patients with large ventral hernia defects who underwent OPP-ACS performed by the authors (B.A.S., M.J.T.) was conducted between 2015 and 2019. Demographics, surgical history, operative details, outcomes, and complications were extracted. A validated questionnaire, Carolinas Comfort Scale (CCS), was used to assess postoperative quality of life.

RESULTS

 Twenty-two patients (12 males and 10 females) with a mean age and BMI of 60.9 ± 10 years and 28.9 ± 4.8 kg/m2, respectively, were included. Mean follow-up was 28.5 ± 16.3 months. All had prior abdominal surgery; 15 (68%) for abdominopelvic malignancy, 3 (14%) for previous failed hernia repair, and 8 (36%) had history of abdominopelvic radiation. Overall, 16 (73%) hernias were in the midline, 4 (18%) in the right lower quadrant, 1 (4.5%) in the right upper quadrant, and 1 (4.5%) in the left lower quadrant. Mean hernia defect surface area was 145 ± 112 cm2. A total of 9 patients (40.9%) underwent bilateral component separation, whereas 13 (59.1%) had unilateral. Bioprosthetic mesh was used in all patients as underlay. Mean mesh size and thickness were 545.6 ± 207.7 cm2 and 3.4 ± 0.5 mm, respectively. One patient presented with a minor wound dehiscence, and two presented with seromas not requiring aspiration/evacuation. One patient had hernia recurrence 22 months after surgery. One patient was readmitted for partial small bowel obstruction and one required wound revision. A total of 14 (65%) patients responded to the CCS questionnaire. At 12 months, mean score for all 23 items was 0.29 ± 0.21 (0.08-0.62), which corresponds to absence or minimal symptoms.

CONCLUSION

 The OPP-ACS is a safe surgical option for large, complex ventral hernias. Our cases showed minimal complication rate and hernia recurrence, and our patients reported significant improvement in life quality.

Kinematic data profile and clinical outcomes in robotic inguinal hernia repairs: a pilot study

BACKGROUND

Surgical training requires clinical knowledge and technical skills to operate safely and optimize clinical outcomes. Technical skills are hard to measure. The Intuitive Data Recorder (IDR), (Sunnyvale, CA) allows for the measurement of technical skills using objective performance indicators (OPIs) from kinematic event data. Our goal was to determine whether OPIs improve with surgeon experience and whether they are correlated with clinical outcomes for robotic inguinal hernia repair (RIHR).

METHODS

The IDR was used to record RIHRs from six surgeons. Data were obtained from 98 inguinal hernia repairs from February 2022 to February 2023. Patients were called on postoperative days 5-10 and asked to take the Carolina Comfort Scale (CCS) survey to evaluate acute clinical outcomes. A Pearson test was run to determine correlations between OPIs from the IDR with a surgeon's yearly RIHR experience and with CCS scores. Linear regression was then run for correlated OPIs.

RESULTS

Multiple OPIs were correlated with surgeon experience. Specifically, for the task of peritoneal flap exploration, we found that 23 OPIs were significantly correlated with surgeons' 1-year RIHR case number. Total angular motion distance of the left arm instrument had a correlation of - 0.238 (95% CI - 0.417, - 0.042) for RIHR yearly case number. Total angular motion distance of right arm instrument was also negatively correlated with RIHR in 1 year with a correlation of - 0.242 (95% CI - 0.420, - 0.046). For clinical outcomes, wrist articulation of the surgeon's console positively correlated with acute sensation scores from the CCS with a correlation of 0.453 (95% CI 0.013, 0.746).

CONCLUSIONS

This study defines multiple OPIs that correlate with surgeon experience and with outcomes. Using this knowledge, surgical simulation platforms can be designed to teach patterns to surgical trainees that are associated with increased surgical experience and with improved postoperative outcomes.

Abdominal Core Health: What Is It?

Abdominal core health encompasses the stability and function of the abdominal core and associated quality of life. Interventions to maintain core health include surgical and non-surgical therapies that integrate the functional relatedness of the abdominal core components.

Short-Term Outcomes and Quality-of-Life Assessment Following Rives-Stoppa and Transversus Abdominis Release Procedures of Open Ventral Hernia Repair

INTRODUCTION

Ventral hernia is one of the common surgical conditions that can significantly impact a patient's quality of life (QoL). Open ventral hernia repair using the Rives-Stoppa (RS) and Transversus Abdominis Release (TAR) procedures has gained recognition for its effectiveness in achieving hernia repair and reducing the risk of further recurrence. However, limited research has been performed to explore the short-term outcomes and QoL assessment following these two surgical techniques. The aim of this study was to know the result after RS and TAR methods of hernia repair in terms of short-term recurrences, pain, postoperative complications, and QoL.

METHODS

This was a prospective, interventional study, which included 30 patients fulfilling the inclusion criteria. The study group was subjected to posterior component separation (PCS)-TAR and RS repair as per surgical indication (RS if defect size 4-10cm; PCS-TAR if defect size >10cm and

RESULTS

Not a single recurrence was observed till POD 180 in either of the repair methods. The mean operative time for RS repair was 170.47 ± 15.08 minutes while for TAR repair was 188.8 ± 22.04 (p-value= 0.013). Surgical site infection (SSI) was reported in 14.28% of RS repair cases and 11.11% of TAR repair cases. Seroma formation was observed in 9.5% of RS repair cases. RS repair has less mean CCS score than TAR. The one-way ANOVA showed f-ratio=421.43 and p-value=0.00001 for RS repair while f-ratio= 298.05 and p-value=0 .00001 for TAR repair at POD seven, POD 30, and POD 90. Both RS and TAR repair markedly reduced mean scores in all three domains on POD 90.

CONCLUSION

Both RS and TAR had no recurrence in a short period of six months. The intraoperative time taken in TAR was less than in earlier studies. QoL improved postoperatively in both the repairs with RS repair having better QoL than TAR repair.

Quality of Life With a Hernia-A Novel Patient Led Study

Introduction: Abdominal wall hernia surgery aims to relieve symptoms and to improve quality of life (QoL). The aim of this novel patient led research, was to help surgeons understand how hernias impact on patients' wellbeing. Methods: A questionnaire was developed by patient advocates. It was promoted through social media to gather anonymous feedback from patients. Results: 264 questionnaires were completed. The majority of the respondents were female (78.4%, n = 207), from English speaking countries (85.2%, n = 225), and had either parastomal hernias (36.0%, n = 95) or incisional hernias (28.0%, n = 74). Respondents described how their hernia affected sexual intimacy, either due to the dislike of their physical appearance, pain or the practicalities of their hernia getting in the way. They reported that their hernia restricted them from engaging in certain exercise activities, and a significant proportion also reported an impact on their diet. Conclusion: This study has identified that in addition to functional problems, living with a hernia can affect mental health as well as social and physical relationships. Existing hernia QoL tools are limited in the outcomes that they measure. Without a comprehensive hernia specific QoL tool, it remains difficult for a surgeon to accurately assess the impact that different treatment modalities may have on patients.

Long term outcomes of robotic-assisted abdominal wall reconstruction: a single surgeon experience

INTRODUCTION

Robotic abdominal wall reconstruction (RAWR) is one of the most significant advances in the management of complex abdominal wall hernias. The objective of this study was to evaluate long term outcomes in a cohort of patients that underwent complex RAWR in a single center.

METHODS

This was a longitudinal retrospective review of a cohort of 56 patients who underwent complex RAWR at least 24 months prior by a single surgeon at a tertiary care institution. All patients underwent bilateral retro-rectus release (rRRR) with or without robotic transversus abdominis release (rTAR). Data collected include demographics, hernia details, operative and technical details. The prospective analysis included a post-procedure visit of at least 24 months from the index procedure with a physical examination and quality of life survey using the Carolinas Comfort Scale (CCS). Patients with reported symptoms concerning for hernia recurrence underwent radiographic imaging. Descriptive statistics (mean ± standard deviation or median) were calculated for continuous variables. Chi-square or Fisher's exact test as deemed appropriate for categorical variables, and analysis of variance or the Kruskal-Wallis test for continuous data, were performed among the separate operative groups. A total score for the CCS was calculated and analyzed in accordance with the user guidelines.

RESULTS

One-hundred and-forty patients met the inclusion criteria. Fifty-six patients consented to participate in the study. Mean age was 60.2 years. Mean BMI was 34.0. Ninety percent of patients had at least one comorbidity and 52% of patients were scored ASA 3 or higher. Fifty-nine percent were initial incisional hernias, 19.6% were recurrent incisional hernias and 8.9% were recurrent ventral hernias. The mean defect width was 9 cm for rTAR and 5 cm for rRRR. The mean implanted mesh size was 945.0 cm² for rTAR and 362.5 cm² for rRRR. The mean length of follow-up was 28.1 months. Fifty-seven percent of patients underwent post-op imaging at an average follow-up of 23.5 months. Recurrence rate was 3.6% for all groups. There were no recurrences in patients that underwent solely bilateral rRRR. Two patients (7.7%) that underwent rTAR procedures were found with recurrence. Average time to recurrence was 23 months. Quality of life survey demonstrated an overall CCS score of 6.63 ± 13.95 at 24 months with 12 (21.4%) patients reporting mesh sensation, 20 (35.7%) reporting pain, and 13 (23.2%) reporting movement limitation.

CONCLUSION

Our study contributes to the paucity of literature describing long term outcomes of RAWR. Robotic techniques offer durable repairs with acceptable quality of life metrics.

Comparing functional outcomes in minimally invasive versus open inguinal hernia repair using the army physical fitness test

PURPOSE

The advantages of minimally invasive inguinal hernia repair (MIHR) over open hernia repair (OHR) continue to be debated. We compared MIHR to OHR by utilizing the Army Physical Fitness Test (APFT) as an outcome measure.

METHODS

The APFT is a three-component test scored on a normalized 300 point scale taken semiannually by active-duty military. We identified 1119 patients who met inclusion criteria: 588 in the OHR group and 531 in the MIHR group. Changes in APFT scores, time on post-operative duty restrictions (military profile), and time interval to first post-operative APFT were compared using regression analysis.

RESULTS

Postoperatively, no APFT score change difference was observed between the OHR or MIHR groups (- 7.3 ± 30 versus - 5.5 ± 27.7, p = 0.2989). Service members undergoing OHR and MIHR underwent their first post-operative APFT at equal mean timeframes (6.6 ± 5 months versus 6.7 ± 5.1, p = 0.74). No difference was observed for time in months spent on an official temporary duty restriction (military profile) for either OHR or MIHR (0.16 ± 0.16 versus 0.15 ± 0.17, p = 0.311). On adjusted regression analysis, higher pre-operative APFT scores and BMI ≥ 30 were independently associated with reduction in post-operative APFT scores. Higher-baseline APFT scores were independently associated with less time on a post-operative profile, whereas higher BMI (≥ 30) and lower rank were independently associated with longer post-operative profile duration. Higher-baseline APFT scores and lower rank were independently associated with shorter time intervals to the first post-operative APFT.

CONCLUSION

Overall, no differences in post-operative APFT scores, military profile time, or time to first post-operative APFT were observed between minimally invasive or open hernioplasty in this military population.

Transinguinal preperitoneal (TIPP) vs endoscopic total extraperitoneal (TEP) procedure in unilateral inguinal hernia repair: a randomized controlled trial

PURPOSE

The Lichtenstein hernioplasty has long been seen as the gold standard for inguinal hernia repair. Unfortunately, this repair is often associated with chronic pain, up to 10-35%. Therefore, several new techniques have been developed, such as the transinguinal preperitoneal patch (TIPP) and the endoscopic total extraperitoneal (TEP) technique. Several studies showed beneficial results of the TIPP and TEP compared to the Lichtenstein hernioplasty; however, little is published on the outcome when comparing the TIPP and TEP procedures. This study aimed to evaluate outcomes after the TIPP vs the TEP technique for inguinal hernia repair.

METHODS

A single-center randomized controlled trial was carried out between 2015 and 2020. A total of 300 patients with unilateral inguinal hernia were enrolled and randomized to the TIPP- or TEP technique. Primary outcome was chronic pain (defined as any pain following the last 3 months) and quality of life, assessed with Carolinas comfort scale (CCS) at 12 months. Secondary outcomes were: wound infection, wound hypoesthesia, recurrence, readmission within 30 days, and reoperation.

RESULTS

A total of 300 patients were randomized (150 per group). After a follow-up of 12 months, we observed significantly less postoperative chronic groin pain, chronic pain at exertion, wound hypoesthesia, and wound infections after the TEP when compared to the TIPP procedure. No significant differences in quality of life, reoperations, recurrence rate, and readmission within 30 days were observed.

CONCLUSION

We showed that the TEP has a favorable outcome compared to the TIPP procedure, leading to less postoperative pain and wound complications, whereas recurrence rates and reoperations were equal in both the groups.

State-of-the-art abdominal wall reconstruction and closure

Open ventral hernia repair is one of the most common operations performed by general surgeons. Appropriate patient selection and preoperative optimization are important to ensure high-quality outcomes and prevent hernia recurrence. Preoperative adjuncts such as the injection of botulinum toxin and progressive preoperative pneumoperitoneum are proven to help achieve fascial closure in patients with hernia defects and/or loss of domain. Operatively, component separation techniques are performed on complex hernias in order to medialize the rectus fascia and achieve a tension-free closure. Other important principles of hernia repair include complete reduction of the hernia sac, wide mesh overlap, and techniques to control seroma and other wound complications. In the setting of contamination, a delayed primary closure of the skin and subcutaneous tissues should be considered to minimize the chance of postoperative wound complications. Ultimately, the aim for hernia surgeons is to mitigate complications and provide a durable repair while improving patient quality of life.

No difference in outcomes between large- and small-pore meshes in a prospective, randomized, multicenter trial investigating open retromuscular meshplasty for incisional hernia repair

STUDY DESIGN

A randomized, controlled, prospective multicenter clinical trial with a parallel group design was initiated in eight surgical centers to compare a large-pore polypropylene mesh (Ultrapro®) to a small-pore polypropylene mesh (Premilene®) within a standardized retromuscular meshplasty for incisional hernia repair.

METHODS

Between 2004 and 2006, patients with a fascial defect with a minimum diameter of 4 cm after vertical midline laparotomy were recruited for the trial. Patients underwent retromuscular meshplasty with either a large-pore or a small-pore mesh to identify the superiority of the large-pore mesh. Follow-up visits were scheduled at 5 and 21 days and 4, 12, and 24 months after surgery. A clinical examination, a modified short form 36 (SF-36®), a daily activity questionnaire, and an ultrasound investigation of the abdominal wall were completed at every follow-up visit. The primary outcome criterion was foreign body sensation at the 12-month visit, and the secondary endpoint criteria were the occurrence of hematoma, seroma, and chronic pain within 24 months postoperatively.

RESULTS

In 8 centers, 181 patients were included in the study. Neither foreign body sensation within the first year after surgery (27.5% Ultrapro®, 32.2% Premilene®) nor the time until the first occurrence of foreign body sensation within the first year was significantly different between the groups. Regarding the secondary endpoints, no significant differences could be observed. At the 2-year follow-up, recurrences occurred in 5 Ultrapro® patients (5.5%) and 4 Premilene® patients (4.4%).

CONCLUSION

Despite considerable differences in theoretical and experimental works, we have not been able to identify differences in surgical or patient-reported outcomes between the use of large- and small-pore meshes for retromuscular incisional hernia repair.

Laparoscopic versus robotic inguinal hernia repair: a single-center case-matched study

INTRODUCTION

Robotic inguinal hernia repair (RIHR) is becoming increasingly common and is the minimally invasive alternative to laparoscopic inguinal hernia repair (LIHR). Thus far, there is little data directly comparing LIHR and RIHR. The purpose of this study will be to compare outcomes for LIHR and RIHR at a single center.

METHODS

A prospective institutional hernia database was queried for patients who underwent transabdominal LIHR or RIHR from 2012 to 2020. The patients were then matched based on the surgeon performing the operation (single, expert hernia surgeon) and laterality of repair. Standard descriptive statistics were used.

RESULTS

There were 282 patients who met criteria for the study, 141 LIHR and 141 RIHR; 32.6% of patients in each group had a bilateral repair (p = 1.00). LIHR patients were slightly younger (54.4 ± 15.6 vs 58.6 ± 13.8; p = 0.03) but similar in terms of BMI (27.1 ± 5.1 vs 29.1 ± 2.1; p = 0.70) and number of comorbidities (2.9 ± 2.5 vs 2.6 ± 2.2; p = 0.59). Operative time was found to be longer in the RIHR group, but when evaluating RIHR at the beginning of the study versus the end of the study, there was a 50-min decrease in operative time (p < 0.01). Recurrence rates were low for both groups (0.7% vs 1.4%; p = 0.38) with mean follow-up time 13.0 ± 13.3 months. There was only one wound infection, which was in the robotic group. No patients required return to the operating room for complications relating to their surgery. There were no 30-day readmissions in the LIHR group and three 30-day readmissions in the RIHR group (p = 0.28).

CONCLUSION

LIHR and RIHR are both performed with low morbidity and have comparable overall outcomes. The total charges were increased in the RIHR group. Either LIHR or RIHR may be considered when performing inguinal hernia repair and should depend on surgeon and patient preference; continued evaluation of the outcomes is warranted.

Slowly absorbable mesh versus standard care in the management of contaminated midline incisional hernia (COMpACT-BIO): a multicentre randomised controlled phase III trial including a health economic evaluation

INTRODUCTION

Incisional hernia (IH) is the most frequent mid-term and long-term complication after midline laparotomy. The current standard treatment includes repair using a mesh. In a contaminated field, the use of a non-absorbable mesh increases the risk of surgical site infection and the costs. Slowly absorbable meshes are safe in contaminated fields, but no data have been reported regarding their long-term recurrence rate. COMpACT-BIO is a multicentre prospective randomised controlled phase III trial designed to compare the 3-year recurrence rate in patients undergoing contaminated IH repair with either a slowly absorbable mesh or standard care.

METHODS

In patients undergoing midline IH repair in a contaminated surgical field (grade III of the modified Ventral Hernia Working Group classification), the COMpACT-BIO study compares the use of a slowly absorbable mesh with that of conventional care according to standardised surgical procedures (primary closure, non-absorbable synthetic mesh or biologic mesh, at the discretion of the surgeon). Randomisation is done during surgery before closure the fascia with an allocation ratio of 1:1. The choice of the slowly absorbable mesh is left to the criteria of each centre. The primary endpoint is the proportion of patients with scan-confirmed IH recurrence within 3 years after repair.

ETHICS/DISSEMINATION

This trial is conducted in compliance with international standards for research practice and reporting. Written informed consent will be obtained from patients prior to inclusion. All data were identified and anonymised prior to analysis. The protocol has been approved by an Institutional Review Board (2020-A0823-36/SI:20.07.03.66831), and will be conducted in compliance with the CONSORT (Consolidated Standards of Reporting Trials) statement. Results will be submitted for publication in peer-reviewed medical journals and presented to patients and healthcare professionals.

Quality of life following laparoscopic inguinal hernia surgery with self-adhesive mesh in 552 patients: a two surgeon experience

BACKGROUND

Given negative publicity surrounding surgical mesh in the media, the aim of this study was to assess post-operative morbidity and quality of life (QoL) following laparoscopic inguinal hernia surgery with self-adhesive ProgripTM mesh.

METHODS

This study is a retrospective analysis of ProgripTM mesh for laparoscopic inguinal hernia repairs by two experienced surgeons in the public and private sectors. Data were collected by screening electronic clinical records. A sample of participants were contacted directly for QoL assessment using the Carolinas Comfort Scale (CCS). Descriptive statistical analysis was performed in Microsoft Excel.

RESULTS

Five hundred and fifty-two patients had 648 hernia repairs using ProgripTM mesh from 2013 to 2019. The rate of hernia recurrence was 0.2% (n = 1). The rate of reoperation was 0.5% (n = 3). There were no mesh explant procedures, no adhesion-related readmissions and no perioperative deaths. Haematoma was the most common post-operative complication, occurring in 3.1% of participants (n = 17). The CCS assessment had a response rate of 55.8%. A total of 93% of CCS questions were answered with no sensation of mesh, 92% with no pain and 98% with no movement limitation. No participants reported severe or disabling symptoms.

CONCLUSION

In this cohort, laparoscopic inguinal hernia repair with ProgripTM has shown a low recurrence rate and excellent post-operative QoL. The QoL data shows that the public perception of mesh based on media reports of complications may not be relevant for this operation. The knowledge gained from this study reinforces the potential value of a national mesh registry such as those seen overseas.

Results from patient-reported outcome measures are inconsistently reported in inguinal hernia trials: a systematic review

PURPOSE

To evaluate the use, results, and reporting of patient-reported outcome measures specific to patients undergoing inguinal hernia repair.

METHODS

A systematic review was performed and reported according to the PRISMA 2020 statement. A protocol was registered at PROSPERO (CRD42021243468). Systematic searches were performed in PubMed and EMBASE. We only included randomized controlled trials that involved postoperative administration of a hernia-specific patient-reported outcome measure. Risk of bias was evaluated with the Cochrane risk of bias-tool 2.0.

RESULTS

Twenty trials and four different instruments were included: the Carolinas Comfort Scale (nine studies), Activities Assessment Scale (six studies), Inguinal Pain Questionnaire (seven studies), and Surgical Pain Scales (one study). Included trials used patient-reported outcome measures and compared either different surgical approaches (11 studies), types of mesh/fixation (seven studies), or types of anesthesia/analgesia (two studies). Results were reported using several different methods including means, medians, or proportions of either overall results, results from subscales, or results from single questionnaire items. Seven of the 20 included studies specified a patient-reported outcome measure as a primary outcome and provided clear reporting of sample size calculation.

CONCLUSION

Reporting of results from patient-reported outcome measures in inguinal hernia research was characterized by heterogeneity. The results were reported using several different methods, which impedes proper evidence synthesis. Only half of the included studies applied a patient-reported outcome measure as primary outcome. Ultimately, the heterogeneity in outcome reporting is an important methodological problem obstructing the full utilization of patient-reported outcome measures in inguinal hernia research.

Adaptation and validation of the Carolinas Comfort Scale: a questionnaire-based cross-sectional study

PURPOSE

Quality of life (QoL) is an important outcome following surgery. The Carolinas Comfort scale (CCS) is a specific questionnaire used to evaluate QoL in patients who underwent abdominal hernia repair with mesh. The aim of this study was to create a Lithuanian version of the CCS.

METHODS

A questionnaire-based cross-sectional study was conducted. A Lithuanian version of the CCS was created by translating the original questionnaire in accordance with the guidelines. The Lithuanian questionnaire was provided to hernia patients at 1 week and at 1 month postoperatively. The main validation characteristics of the Lithuanian CCS were assessed and compared to the original version.

RESULTS

The complete response rate of patients was close to 90%. Internal consistency was excellent, with a Cronbach's α of 0.953. Correlation coefficients ranged from 0.361 to 0.703 in the test-retest analysis. In the construct validity analysis, the strongest correlations were observed in the domains of physical functioning and bodily pain (- 0.655 and - 0.584, respectively) and the weakest correlations in role-emotional and mental health (- 0.268 and - 0.230, respectively). The mean scores of all CCS domains and the total score for satisfied patients were significantly lower (p < 0.001) than those of dissatisfied patients. The principal component analysis identified 3 components, with the first accounting for 56% of the variance.

CONCLUSIONS

The Lithuanian version of CCS maintains the original validity and is a reliable and valid tool for assessing specific QoL factors after the repair of inguinal hernia with mesh. We recommend using this CCS version in personal, local, and international contexts.

Transcutaneous Electric Nerve Stimulation Reduces Pathological Sensation of Mesh One Week after Open Inguinal Hernia Surgery: Follow-Up Results from a Randomized, Double Blind and Placebo-Controlled Trial

Background and Objectives: Quality of life (QoL) and chronic pain are important outcomes following hernia surgery. The long-term effects of Transcutaneous Electric Nerve Stimulation (TENS) on postoperative recovery are not well known. In this trial we investigated the role of TENS on QoL and on the incidence of chronic pain following inguinal hernia repair with mesh. Materials and Methods: A total of 80 male patients with elective primary unilateral hernia Lichtenstein repair were randomly allocated to receive TENS or a placebo-TENS procedure. The TENS group received conventional TENS twice a day on the first and second postoperative days. The intensity was set at 0–0.5 mA in the placebo-TENS group. General and hernia-specific QoL, as well as the incidence of chronic pain were assessed using SF-36v2 and the Carolinas comfort scale. Results: Less sensation of mesh was reported by the TENS group patients one week after surgery. At this time point, the mean sensation score was 6.07 ± 8.88 in the TENS group and 14.08 ± 16.67 in the placebo-TENS group (p = 0.029). Although at two days and one week postoperatively, TENS group patients tended to have less pain, less movement restrictions and better overall hernia-specific QoL, the differences were not statistically significant. At 6 months postoperatively, no incidence of chronic pain was found in either the placebo-TENS or TENS group. Conclusions: Conventional TENS applied in the early postoperative period following inguinal hernia repair with mesh was found to reduce mesh-related foreign body sensation one week after surgery. Promising results were also found for other QoL domains.

[Pain and quality of life after laparoscopic transabdominal preperitoneal hernioplasty with different ways of fixing the peritoneum. Results of early completion randomized clinical trial]

OBJECTIVE

To compare and statistically evaluate the severity of pain syndrome and quality of life depending on the method of fixation of the parietal peritoneum during laparoscopic hernia repair (suture fixation or the use of tack fixation).

METHODS

A randomized clinical trial was conducted from May to June 2021 at the Lomonosov Moscow State University Medical Center. It was planned to observe patients for a year. In the first group, the fixation of the parietal peritoneum was performed using suture fixation, in the second group, the peritoneal flap was fixed using a fixation device. In the course of statistical data processing, it was planned to study the dependence of the duration of the operation, the severity of the pain syndrome in the early postoperative period, the frequency of complications, the quality of life of patients in the postoperative period on the chosen method of the fixation of the parietal peritoneum.

RESULTS

At the initial stage of the study, 8 patients with inguinal hernias were selected in the first group during randomization, and 6 patients were selected in the second group. Each patient of the second group in the early postoperative period had a more pronounced local pain, protective muscle tension in the projection of fixation of the parietal peritoneum with tacks, which was accompanied by negative psychoemotional reactions, an increase in the dose of analgesic drugs. Due to the revealed features of the early postoperative period in patients of second group, it was considered unethical and inappropriate to continue the study within the protocol.

CONCLUSION

The results obtained do not allow us to draw statistically supported conclusions. The solution of the problem of the peritoneal flap fixation method is possible in two ways: abandoning stapler fixation in favor of suture or conducting additional clinical studies with an analysis of the impact of the choice of peritoneal fixation technique not only on acute and chronic postoperative pain, but on quality of life in the early and delayed postoperative periods.

Nationwide Readmissions Analysis of Minimally Invasive Versus Open Ventral Hernia Repair: A Retrospective Population-Based Study

INTRODUCTION

Minimally invasive ventral hernia repair (MISVHR) has been performed for almost 30 years; recently, there has been an accelerated adoption of the robotic platform leading to renewed comparisons to open ventral hernia repair (OVHR). The present study evaluates patterns and outcomes of readmissions for MISVHR and OVHR patients.

METHODS

The Nationwide Readmissions Database (NRD) was queried for patients undergoing OVHR and MISVHR from 2016 to 2018. Demographic characteristics, complications, and 90-day readmissions were determined. A subgroup analysis was performed to compare robotic ventral hernia repair (RVHR) vs laparoscopic hernia repair (LVHR). Standard statistical methods and logistic regression were used.

RESULTS

Over the 3-year period, there were 25 795 MISVHR and 180 635 OVHR admissions. Minimally invasive ventral hernia repair was associated with a lower rate of 90-day readmission (11.3% vs 17.3%, P < .01), length of stay (LOS) (4.0 vs 7.9 days, P < .01), and hospital charges ($68,240 ± 75 680 vs $87,701 ± 73 165, P < .01), which remained true when elective and non-elective repairs were evaluated independently. Postoperative infection was the most common reason for readmission but was less common in the MISVHR group (8.4% vs 16.8%, P < .01). Robotic ventral hernia repair increased over the 3-year period and was associated with decreased LOS (3.7 vs 4.1 days, P < .01) and comparable readmissions (11.3% vs 11.2%, P = .74) to LVHR, but was nearly $20,000 more expensive. In logistic regression, OVHR, non-elective operation, urban-teaching hospital, increased LOS, comorbidities, and payer type were predictive of readmission.

CONCLUSIONS

Open ventral hernia repair was associated with increased LOS and increased readmissions compared to MISVHR. Robotic ventral hernia repair had comparable readmissions and decreased LOS to LVHR, but it was more expensive.

Controversies in Abdominal Wall Reconstruction

This article discuses current controversies in abdominal wall reconstruction, including the standardization of outcome reporting, mesh selection, the utility of robotic surgery in ventral hernia repair, and role for prophylactic stoma mesh at the time of permanent end colostomy formation. The current state of the literature pertaining to these topics is reviewed in detail.

Fascial defect closure versus bridged repair in laparoscopic ventral hernia mesh repair: a systematic review and meta-analysis of randomized controlled trials

PURPOSE

Several studies have examined effectiveness of primary fascial defect closure (FDC) versus bridged repair (no-FDC) during laparoscopic ventral hernia mesh repair (LVHMR). The purpose of this study was to systematically review and meta-analyse randomized controlled trials (RCTs) which compared safety and effectiveness of two techniques.

METHODS

Systematic literature searches (EMBASE, MEDLINE, PubMed, and CINAHL) were conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines using predefined terms. RCTs comparing FDC and no-FDC in LVHMR were identified and retrieved. Primary outcomes were risk of recurrence and risk of major complications analyzed as a single composite outcome. Secondary outcomes were risks of seroma formation, clinical or radiologically confirmed eventration, incidence of readmission to hospital, postoperative changes in quality of life (QoL), and postoperative pain. Random effects modeling to summarize statistics were performed. The risk of bias was assessed using Cohrane's Risk of Bias tool 2.

RESULTS

Three RCTs that enrolled total of 259 patients were included. There was clinical heterogeneity present between studies related to patients' characteristics, hernia characteristics, and operative techniques. There was no difference found in primary outcomes, risks of seroma formation, eventration, and chronic pain. There is conflicting evidence on how both techniques affect postoperative QoL or early postoperative pain.

CONCLUSIONS

Both techniques were detected to have equal safety profile and do not differ in risk of recurrence, seroma formation, risks of clinical or radiological eventration. Giving uncertainty and clinical equipoise, another RCT examining FDC vs no-FDC laparoscopic mesh repair separately for primary and secondary hernias using narrow inclusion criteria for hernia size on well-defined population would be ethical and pragmatic.

Predictors of low quality of life after open inguinal hernia repair using the EuraHS-QoL score: prospective multicentric cohort study across 33 hospitals

PURPOSE

Evidence about factors influencing quality of life after inguinal hernia surgery is scarce. This study aimed to assess patient's Quality of Life (QoL) after open inguinal hernia repair and to identify predictors of low QoL at 3 months after surgery, to guide practice and inform patients at high risk.

METHODS

Prospective multicentric cohort study including consecutive patients undergoing elective open inguinal hernia repair in Portuguese hospitals (October-December 2019). The primary outcome was Quality of Life at 3 months after surgery, using the EuraHS-QoL score (higher score correlates with lower QoL). Low QoL was defined as the higher EuraHS-QoL score tertile and multivariate logistic regression was used to identify predictors.

RESULTS

893 patients were included from 33 hospitals. The majority were men [89.9% (800/891)], had unilateral hernias 88.7% (774/872) and the most common surgical technique was Lichtenstein's repair [52.9% (472/893)]. The median QoL score was 24 (IQR 10-40) before surgery and 2 (IQR 0-10) at 3 months after surgery, showing significant improvement (p < 0.001). After adjustment, low QoL at 3 months was associated with low preoperative QoL (OR 1.76, 95% CI 1.21-2.57, p = 0.003), non-absorbable mesh fixation (OR 1.64, 95% CI 1.12-2.41, p = 0.011), severe immediate postoperative pain (OR 2.90, 95% CI 1.66-5.11, p < 0.001) and minor postoperative complications (OR 2.23, 95% CI 1.30-3.84, p = 0.004).

CONCLUSION

This study supports the use of the EuraHS-QoL score preoperatively to inform consent. Although significant improvement in QoL is expected after surgery, high scores before surgery are associated with low postoperative QoL. Caution should be taken with non-absorbable mesh fixation and immediate postoperative pain control should be optimised.

Quality of Life After Umbilical Hernia Repair

BACKGROUND

Mesh is beneficial in the repair of umbilical hernias. But it may cause chronic pain due to inflammatory reactions, which may impair the patient's quality of life.

OBJECTIVES

To assess and compare the quality of life of patients following umbilical hernia repair with and without mesh.

METHODS

 During the study period, 45 patients underwent umbilical hernia repair. The study was conducted at King Abdul-Aziz University Hospital (KAUH), KSA. Data were collected using medical records, and each patient was contacted by telephone, to fill the "Carolina Comfort Scale (CCS)" survey. The survey assesses the grade of pain, sensation of mesh, and movement limitation in different situations.

RESULTS

A non-significant difference was found between mean quality of life (QOL) scores of mesh and non-mesh groups. The relationship between CCS and gender was not significant in both groups. However, males had significantly higher CCS scores in mesh-treated cases. There was no statistically significant relationship between CCS and comorbidity, nationality, or symptoms. The overall CCS score did not differ statistically between mesh-treated and non-mesh-treated cases.  Conclusion: The CCS score did not differ between mesh-treated and non-mesh-treated cases. It is suggested that future multicentric studies with a larger sample size be conducted.

Case Report: How an Iliac Vein Lesion During Totally Endoscopic Preperitoneal Repair of an Inguinal Hernia Can Be Safely Managed

Inguinal hernia repair is a common surgical procedure with an acceptably low complication rate. However, complications with potentially life-threating consequences may occur in rare cases. These complications might be very challenging to manage, even more in laparo-endoscopic interventions compared to open repair. One of these challenges can be the treatment of an intraoperative injury to the iliac vein. To the best of our knowledge, a lesion of the iliac vein during TEP (totally endoscopic preperitoneal) for inguinal hernia repair, and a safe technique for its management have not been reported yet. We report the case of a 75-year-old male patient with previous abdominal surgery scheduled for TEP repair of an inguinal hernia. During surgery, the iliac vein was damaged. If we had performed a laparotomy in this situation, the potentially life-threatening condition of the patient could have deteriorated further. Instead, to avoid a potential CO₂ associated embolism, the preperitoneal pressure was gradually reduced, and the positive end expiratory pressure (PEEP) was increased in the manner that a balance between excessive bleeding and potential development of a CO₂ embolism was achieved. The injured vein was sutured endoscopically, and in addition a hemostatic patch was applied. We then continued with the planned surgical procedure. Thrombosis of the sutured vein was prevented by prophylactic administration of low molecular weight heparin until the 14th postoperative day. We conclude that in case of major vein injury during TEP, which might happen irrespective of prior abdominal surgery, the preperitoneal pressure and PEEP adjustment can be used to handle the complication.

Patient-reported outcomes after incisional hernia repair

Purpose

Patient-reported outcomes (PROs) are pivotal to evaluate the efficacy of surgical management. Debate persists on the optimal surgical technique to repair incisional hernias. Assessment of PROs can guide the selection of the best management of patients with incisional hernias. The objective of this cohort study was to present the PROs after incisional hernia repair at long term follow-up.

Methods

Patients with a history of incisional hernia repair were seen at the out-patient clinic to collect PROs. Patients were asked about the preoperative indication for repair and postoperative symptoms, such as pain, feelings of discomfort, and bulging of the abdominal wall. Additionally, degree of satisfaction was asked and Carolina Comfort Scales were completed.

Results

Two hundred and ten patients after incisional hernia repair were included with a median follow-up of 3.2 years. The main indication for incisional hernia repair was the presence of a bulge (60%). Other main reasons for repair were pain (19%) or discomfort (5%). One hundred and thirty-two patients (63%) reported that the overall status of their abdominal wall had improved after the operation. Postoperative symptoms were reported by 133 patients (63%), such as feelings of discomfort, pain and bulging. Twenty percent of patients reported that the overall status of their abdominal wall was the same, and 17% reported a worse status, compared to before the operation. Ten percent of the patients would not opt for operation in hindsight.

Conclusion

This study showed that a majority of the patients after incisional hernia repair still report pain or symptoms such as feelings of discomfort, pain, and bulging of the abdominal wall 3 years after surgery. Embedding patients’ expectations and PROs in the preoperative counseling discussion is needed to improve decision-making in incisional hernia surgery.

Long-term outcomes of single-incision versus multiport laparoscopic totally extra-peritoneal inguinal hernia repair: a single-institution experience of 186 consecutive cases

PURPOSE

This retrospective study was conducted to compare the long-term outcomes of single-incision totally extraperitoneal (S-TEP) inguinal hernia repair and conventional multiport totally extraperitoneal (M-TEP) inguinal hernia repair.

METHODS

The study population included 186 consecutive patients (S-TEP, n = 149; M-TEP, n = 37) who underwent elective surgery for inguinal hernia at Osaka Police Hospital between 2011 and 2013.

RESULTS

No significant between-group difference was found in patient or hernia characteristics or in perioperative outcomes, with the exception of age (S-TEP group vs. M-TEP group: median 69 [IQR 60-75] years vs. 64 [55-69] years, respectively; P = 0.019). Furthermore, no significant between-group difference was found in follow-up time (5.5 [3.0-5.8] vs. 5.4 [3.1-5.7] years, P = 0.839), recurrence rate (0.6 vs. 2.4%, P = 0.358), chronic pain (1.2 vs. 0%, P = 1.000), feeling the mesh (2.3 vs. 7.1%, P = 0.142), or movement limitation (0.6 vs. 0%, P = 1.000). All chronic symptoms were "mild but not bothersome." A metachronous contralateral inguinal hernia developed in 8.1% of patients.

CONCLUSION

The long-term outcomes of S-TEP repair were comparable to those of M-TEP, with rates of recurrence, chronic pain, feeling the mesh, and movement limitation falling within acceptable limits.

Longitudinal cohort study on preoperative pain as a risk factor for chronic postoperative inguinal pain after groin hernia repair at 2-year follow-up

PURPOSE

To assess the rate of late chronic postoperative inguinal pain (CPIP) after groin hernia repair in patients with different categories of preoperative VRS (Verbal Rating Scale) pain and to make a pragmatic evaluation of the rates of potentially surgery-related CPIP vs. postoperative continuation of preexisting preoperative pain.

METHODS

Groin pain of patients operated from 01/11/2011 to 01/04/2014 was assessed preoperatively, postoperatively and at 2-year follow-up using a VRS-4 in 5670 consecutive groin hernia repairs. A PROM (Patient Related Outcomes Measurement) questionnaire studied the impact of CPIP on the patients' daily life.

RESULTS

Relevant (moderate or severe VRS) pain was registered preoperatively in 1639 of 5670 (29%) cases vs. 197 of 4704 (4.2%) cases at the 2-year follow-up. Among the latter, 125 (3.7%) cases were found in 3353 cases with no-relevant preoperative pain and 72 (5.3%) in 1351 cases with relevant preoperative pain. Relevant CPIP consisted of 179 (3.8%) cases of moderate pain and 18 (0.4%) cases of severe pain. The rate of severe CPIP was independent of the preoperative VRS-pain category while the rate of moderate CPIP (3.1%, 3.4%, 4.1%, 6.8%) increased in line with the preoperative (none, mild, moderate, and severe) VRS-pain categories. The VRS probably overestimated pain since 71.6% of the relevant CPIP patients assessed their pain as less bothersome than the hernia.

CONCLUSION

At the 2-year follow-up, relevant CPIP was registered in 4.2% cases, of which 63.5% were potentially surgery-related (no-relevant preoperative pain) and 36.5% possibly due to the postoperative persistence of preoperative pain. The rate of severe CPIP was constant around 0.4%.

Quality of life after open versus laparoscopic preperitoneal mesh repair for unilateral inguinal hernias

BACKGROUND

Both the open transinguinal preperitoneal repair (TIPP) and the laparoscopic total extraperitoneal mesh repair (TEP) show excellent outcomes. Direct comparative data between these 2 preperitoneal techniques is lacking. The aim of this study was to assess postoperative outcomes and quality of life (QoL) for these open and laparoscopic preperitoneal repair techniques.

METHODS

Between 2014 and 2016, 204 male patients underwent unilateral inguinal hernia repair through TIPP (n = 135) or TEP (n = 69). Data recorded include demographic profile, preoperative and intraoperative variables, postoperative complications and postoperative quality of life. Two validated hernia-specific QoL questionnaires, the Carolinas Comfort Scale (CCS) and the European Registry for Abdominal Wall Hernias Quality of Life score (EuraHS QoL) were used to assess postoperative QoL.

RESULTS

The TIPP group consisted of 135 patients, the TEP group of 69 patients. The mean age of patients was significantly higher in TIPP (64.07 ± 17.10 years) than in TEP (59.0 ± 15.53 years) (p = 0.022). A total of 96 patients (47.1%) responded to our invitation for longterm follow-up: 58 in the TIPP group (43%) and 38 in the TEP group (55.1%). There was no difference in mean follow-up time between the surgical procedure and filling in the questionnaires: 37.4 ± 12.8 months for TIPP and 33.5 ± 11.3 months for TEP group (p = 0.13). No significant differences in quality of life were found between TIPP and TEP for all explored domains.

CONCLUSION

TIPP and TEP show equivalent results considering postoperative quality of life. Compared to existing literature on mesh repair for unilateral inguinal hernias, we may conclude that the preperitoneal location of the mesh probably is a more decisive factor for quality of life than the surgical approach used.

A systematic review of outcome reporting in incisional hernia surgery

Background

The incidence of incisional hernia is up to 20 per cent after abdominal surgery. The management of patients with incisional hernia can be complex with an array of techniques and meshes available. Ensuring consistency in reporting outcomes across studies on incisional hernia is important and will enable appropriate interpretation, comparison and data synthesis across a range of clinical and operative treatment strategies.

Methods

Literature searches were performed in MEDLINE and EMBASE (from 1 January 2010 to 31 December 2019) and the Cochrane Central Register of Controlled Trials. All studies documenting clinical and patient-reported outcomes for incisional hernia were included.

Results

In total, 1340 studies were screened, of which 92 were included, reporting outcomes on 12 292 patients undergoing incisional hernia repair. Eight broad-based outcome domains were identified, including patient and clinical demographics, hernia-related symptoms, hernia morphology, recurrent incisional hernia, operative variables, postoperative variables, follow-up and patient-reported outcomes. Clinical outcomes such as hernia recurrence rates were reported in 80 studies (87 per cent). A total of nine different definitions for detecting hernia recurrence were identified. Patient-reported outcomes were reported in 31 studies (34 per cent), with 18 different assessment measures used.

Conclusions

This review demonstrates the significant heterogeneity in outcome reporting in incisional hernia studies, with significant variation in outcome assessment and definitions. This is coupled with significant under-reporting of patient-reported outcomes.

e-TEP repair for midline primary and incisional hernia: technical considerations and initial experience

INTRODUCTION

The Enhanced-View Totally Extra Peritoneal Rives-Stoppa (e-TEP-RS) Technique for the repair of large, complex, ventral abdominal hernias has gained popularity especially in overcoming the disadvantages with Intra Peritoneal Onlay Mesh (IPOM) repairs and to enable siting of a large prosthetic mesh in an anatomical plane distinct from the abdominal cavity and its contents. Evolving variations of the original technique have allowed the definitive repair of such defects in a reproducible manner. We present our initial experience of this approach and detailed steps of our native technical modifications in overcoming the challenges in performing this complex and potentially challenging procedure.

MATERIALS AND METHODS

This is a retrospective review of the clinical data of midline, large, complex, ventral abdominal hernia patients who underwent e-TEP-RS with and without Transversus Abdominis Release (TAR). Patients, with or without Diastasis of Rectus Abdominis Muscle (DRAM) were included. Key outcomes measured were post-operative pain, operative morbidity, readmission, Quality of Life (QoL), hernia recurrence.

RESULTS

A total of 58 midline, ventral abdominal hernia patients who underwent e-TEP-RS with and without Transversus Abdominis Release (TAR), between March 2018 and December 2019 were studied. Mean defect area was 41.0 ± 28 cm² and the mean mesh surface area was 473.5 ± 165 cm². e-TEP-RS was done in 35 cases, e-TEP RS TAR in 15 cases and e-TEP-RS with e-TEP inguinal in 08 cases. There was no intraoperative morbidity. Mean duration of surgery was 156.2 ± 40 min and mean blood loss was 40.5 ± 26 cc. The CCS QoL scores improved from 34.6 (± 2) pre-operatively to 27.2 (± 4) at the end of 6 months. One patient had a supra-umbilical recurrence following bilateral TAR over the superior edge of the mesh. Follow-up ranged from 6 to 22 months, with a mean of 14 months. Major complications (n = 12; 20.7%) were seroma formation and prolonged ileus.

CONCLUSION

The e-TEP-RS technique for large, complex, midline, ventral abdominal hernias can be used with excellent results and acceptable morbidity. This technique is technically challenging and should be mastered in relatively smaller ventral hernias to achieve good results before attempting it in larger, complex ones.

Measuring quality of life in patients with abdominal wall hernias: a systematic review of available tools

INTRODUCTION

Abdominal wall herniation (AWH) is an increasing problem for patients, surgeons, and healthcare providers. Surgical-site specific outcomes, such as infection, recurrence, and mesh explantation, are improving; however, successful repair still exposes the patient to what is often a complex major operation aimed at improving quality of life. Quality-of-life (QOL) outcomes, such as aesthetics, pain, and physical and emotional functioning, are less often and less well reported. We reviewed QOL tools currently available to evaluate their suitability.

METHODS

A systematic review of the literature in compliance with PRISMA guidelines was performed between 1st January 1990 and 1st May 2019. English language studies using validated quality-of-life assessment tool, whereby outcomes using this tool could be assessed were included.

RESULTS

Heterogeneity in the QOL tool used for reporting outcome was evident throughout the articles reviewed. AWH disease-specific tools, hernia-specific tools, and generic tools were used throughout the literature with no obviously preferred or dominant method identified.

CONCLUSION

Despite increasing acknowledgement of the need to evaluate QOL in patients with AWH, no tool has become dominant in this field. Assessment, therefore, of the impact of certain interventions or techniques on quality of life remains difficult and will continue to do so until an adequate standardised outcome measurement tool is available.

Inguinal hernia mesh is safe in 1720 patients

BACKGROUND

There is substantial media and patient interest in the safety of mesh for hernia repair. However, there is a lack of data regarding health-related quality of life (HRQOL) outcomes in patients who undergo inguinal hernia repair (IHR) with mesh. The purpose of this study is report short and long-term postoperative quality of life outcomes in patients following IHR with mesh.

METHODS

We analyzed outcomes of 1720 patients who underwent IHR with mesh between 2008 and 2019 at a single institution from a prospectively maintained quality database. All surgeries were performed by four board-certified surgeons. HRQOL outcomes were measured using the Surgical Outcomes Measurement System (SOMS) and Carolinas Comfort Scale (CCS) surveys that were administered preoperatively, 3 weeks, 6 months, 1, 2, and 5 years postoperatively. Survey responses were summarized as mean with standard deviation or frequency with percentage. Postoperative SOMS scores were compared to preoperative scores using the two-tailed paired t test with a significance level of p < 0.05.

RESULTS

One (0.1%) patient experienced a mesh infection postoperatively. In terms of complications, 159 (9.2%) developed a seroma, 31 (1.8%) a hematoma, and 36 (2.1%) patients experienced a recurrence. SOMS Pain Impact, SOMS Pain Quality, and SOMS Pain visual analog scale at 3 weeks, 6 months, 1 year, 2 years, and 5 years were all improved from preoperative (all p < 0.05). At 5 years postoperatively, only 3.9%, 3.2%, and 3.1% of patients reported severe or disabling sensation of mesh, pain, and movement limitations, respectively.

CONCLUSION

Inguinal hernia repair with mesh results in a low rate of complications. A minority of patients had severe or disabling symptoms at 5-year follow-up and generally reported improvements in pain impact and quality in long-term follow-up.
