No difference in sexual dysfunction after transabdominal preperitoneal (TAPP) approach for inguinal hernia with fibrin sealant or tacks for mesh fixation

Pain with sexual activity at 1 and 3 years: Comparing total extraperitoneal with Lichtenstein inguinal hernia repair in a randomized setting (TEPLICH trial)

BACKGROUND

Pain at sexual activity induced by an inguinal hernia or as a cause of its repair is not thoroughly studied. Reported frequencies are between 25% and 30% preoperatively and 10% and 15% postoperatively. The primary aim was to analyze pain at sexual activity at 1 year comparing total extraperitoneal with Lichtenstein repair in a randomized setting.

METHODS

Men, 30 to 60 years old, with a primary inguinal hernia were randomized to total extraperitoneal without mesh fixation or Lichtenstein repair. A questionnaire on pain prevalence, frequency, intensity, and impairment of sexual functions caused by pain at sexual activity was introduced. Clinical examination, a questionnaire on sexual function, and the 36-Item Short Form Survey were performed preoperatively and at 1 and 3 years postoperatively. A risk factor analysis for pain at sexual activity as performed.

RESULTS

A total of 243 patients (111 total extraperitoneal and 132 Lichtenstein) were included between 2008 and 2014; 97% remained for 1-year and 90% for 3-year analysis. Preoperative pain at sexual activity was reported in 35%, with a reduction to 5.9% in total extraperitoneal and 12.5% in Lichtenstein (P = .098) at 1 year and 7.0% in total extraperitoneal and 9.3% in Lichtenstein (P = .566) at 3 years. Quality of life preoperatively was markedly reduced in patients with pain at sexual activity but restored almost to norm levels at 1 and 3 years. New pain at sexual activity (harm) was seen in 8 patients (3.6%) at 1 year. Risk factors for having postoperative pain at sexual activity were preoperative pain and Lichtenstein technique.

CONCLUSION

Pain at sexual activity in inguinal hernia patients is more common than suspected and reduces quality of life. Repair will markedly reduce pain at sexual activity and restore quality of life in most patients without difference between techniques. Patients should be informed on a potential relation between having an inguinal hernia and sexual impairment.

Pain and Dysfunction with Sexual Activity after Inguinal Hernia Repair: Systematic Review and Meta-Analysis

BACKGROUND

The reported incidence rates of sexual dysfunction (SD) and pain with sexual activity (PSA) after inguinal hernia repair in males vary considerably. This meta-analysis explores the rates of SD and PSA after different surgical and anesthesia types to understand patient risk after inguinal hernia repair.

STUDY DESIGN

We performed a systematic review and meta-analysis using Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines to search 3 databases (EMBASE, MEDLINE, and Cochrane Library). We identified retrospective, prospective, and randomized controlled trial studies, published on or before March 1, 2019, reporting on SD and PSA after inguinal hernia repair. We used random-effects models to calculate pooled estimates of incidence rates of SD and PSA after inguinal hernia repair. Subgroup meta-analyses and meta-regression were used to explore sources of variation.

RESULTS

A total of 4,884 patients from 12 studies were identified. Study-level median age at the time of repair was 52.3 years old, and study-level median follow-up was 10.5 months. Definitions of SD and PSA focused on completion of intercourse for the former and pain with erection/ejaculation for the latter. The overall incidence of new-onset, postoperative SD was 5.3% (95% CI 3.6% to 7.9%) and of PSA was 9.0% (95% CI 5.8% to 13.6%). Rates of SD associated with minimally invasive surgical (MIS) and open repair were, respectively, 7.8% (95% CI 5.4% to 11.3%) and 3.7% (95% CI 2.0% to 6.8%); rates of PSA were 7.4% (95% CI 4.7% to 11.5%) and 12.5% (95% CI 6.4% to 23.3%), respectively.

CONCLUSIONS

Sexual dysfunction and PSA are not rare after inguinal hernia repair. They should be included in preoperative discussions and as standard metrics in reporting outcomes of repair in large cohorts or trials.

An overlooked complication of the inguinal hernia repair: Dysejaculation

The objective of this study was to investigate the rate of post-herniorrhaphy dysejaculation in the current literature. A comprehensive search of PubMed, Medline, Google Scholar, and Google databases was performed using the keywords "groin hernia and chronic pain," "inguinal hernia and chronic pain," "dysejaculation," and "ejaculatory pain." The eligible studies were evaluated in terms of ejaculatory pain and surgical technique used. Ten studies with 122 patients were eligible for the analysis. The rate of ejaculatory pain for a total of 5521 patients was found to be 2.2%. The incidence of postoperative ejaculatory pain was found to be 2.1% following laparoscopic techniques and 1.1 % following open repair. Open techniques were not related to the increased frequency of dysejaculation. Sufficient data could not be obtained from the studies for the ejaculatory pain, and thus, no statistical evaluation was performed. Dysejaculation is a common cause of postoperative morbidity after inguinal hernia repair. Attention to technical details of the primary operation may reduce the incidence of dysejaculation.

Decreasing prevalence of chronic pain after laparoscopic groin hernia repair: a nationwide cross-sectional questionnaire study

PURPOSE

Up to 6-7% of patients who have undergone laparoscopic groin hernia repair suffer from chronic pain, depending on various factors; however, the long-term course is unclear. The purpose of this study was to assess the prevalence of chronic pain 1-5 years after laparoscopic groin hernia repair.

METHODS

The subjects of this nationwide cross-sectional questionnaire study were adults who underwent laparoscopic mesh repair of an inguinal or a femoral hernia. The patients were identified from the Danish Hernia Database, which has a follow-up rate of almost 100%. The prevalence of chronic pain was assessed 1-5 years postoperatively by the validated inguinal pain questionnaire (IPQ).

RESULTS

A total of 1383 groins were included in this study, based on a 66% response rate to the questionnaire. The prevalence of pain decreased, especially 3.5 years postoperatively. There were no statistically significant differences when each postoperative year was compared with the second postoperative year. However, the prevalence of chronic pain 3.5-5 years postoperatively was significantly lower (4.4%) than that 1-3.5 years postoperatively (8.1%) (p = 0.014). The prevalence of pain that could not be ignored was still 5-6% in the fifth postoperative year.

CONCLUSIONS

The prevalence of chronic pain seems to decline 1-5 years after laparoscopic groin hernia repair, with a distinct decrease 3.5 years postoperatively.

Data and outcome of inguinal hernia repair in hernia registers - a review of the literature

Register-based observational studies in inguinal hernia repair deliver real-world data from very large patient populations and give answers to important clinical questions never evaluated in randomized controlled trials. Data from hernia registers can provide evidence of effectiveness of therapies in the general population. Hernia registers with high case load have existed in Sweden since 1992, in Denmark since 1998, and in Germany/Austria/Switzerland since 2009. In this review, the most important findings of register-based observational studies in inguinal hernia repair are presented. After an intensive literature search, 85 articles are relevant for this review. Numerous findings from these register-based studies have been incorporated into the various guidelines on inguinal hernia repair. These highlight the particular importance of hernia registers in answering key scientific and clinical questions in hernia surgery. The myriad of surgical techniques described – spanning more than 100 and with ongoing new additions – as well as the large number of associated medical devices call for, more than in other surgical disciplines, meticulous documentation of the methods used for the treatment of inguinal hernias.
