Is young age a risk factor for chronic postoperative inguinal pain after endoscopic totally extraperitoneal (TEP) repair?

Athletes treated for inguinal-related groin pain by endoscopic totally extraperitoneal (TEP) repair: long-term benefits of a prospective cohort

PURPOSE

Inguinal-related groin pain (IRGP) in athletes is a multifactorial condition, posing a therapeutic challenge. If conservative treatment fails, totally extraperitoneal (TEP) repair is effective in pain relief. Because there are only few long-term follow-up results available, this study was designed to evaluate effectiveness of TEP repair in IRGP-patients years after the initial procedure.

METHODS

Patients enrolled in the original, prospective cohort study (TEP-ID-study) were subjected to two telephone questionnaires. The TEP-ID-study demonstrated favorable outcomes after TEP repair for IRGP-patients after a median follow-up of 19 months. The questionnaires in the current study assessed different aspects, including, but not limited to pain, recurrence, new groin-related symptoms and physical functioning measured by the Copenhagen Hip and Groin Outcome Score (HAGOS). The primary outcome was pain during exercise on the numeric rating scale (NRS) at very long-term follow-up.

RESULTS

Out of 32 male participants in the TEP-ID-study, 28 patients (88%) were available with a median follow-up of 83 months (range: 69-95). Seventy-five percent of athletes were pain free during exercise (p < 0.001). At 83 months follow-up, a median NRS of 0 was observed during exercise (IQR 0-2), which was significantly lower compared to earlier scores (p <0.01). Ten patients (36%) mentioned subjective recurrence of complaints, however, physical functioning improved on all HAGOS subscales (p <0.05).

CONCLUSION

This study demonstrates the safety and effectivity of TEP repair in a prospective cohort of IRGP-athletes, for whom conservative treatment had failed, with a follow-up period of over 80 months.

Evaluation of inguinal hernia repair using post-operative pain and quality of life metrics

BACKGROUND AND PURPOSE

Elective inguinal hernia repair is a ubiquitous procedure that carries risks; chronic pain and impacts on quality of life (QoL) must be considered when advising patients around repair. The length of time from surgery date and impacts on quality of life are often limited to only a few years of follow-up and despite hernia repair being quite common, long-term outcomes are not often reported.

METHODS

A cohort of patients who had received Lichtenstein inguinal hernia repair over the previous 10 years were contacted and surveyed using the Brief Pain Inventory Short Form (BPI) to assess chronic pain and its effects on their QoL. Patient and operative factors were correlated with pain through linear regression and t-test analysis provided statistical significance for mean comparisons (P < 0.05).

RESULTS

The rate of chronic pain was 17.2% with recurrence of 3.1% at an average post-operative interval of 5.84 years. Of the various metrics compared between groups, age was one of the only significant predictors of chronic pain with younger patients reporting higher pain. Further time from surgery also translated to significantly less pain with a difference of 1.3 years. BPI respondents identified pain that interfered to varying degrees in different aspects of life but had relatively low average magnitudes (range: 1.82/10-2.91/10).

CONCLUSIONS

These long-term considerations of post-surgical impact should be considered alongside potential benefits when advising patients about surgery and may help moderate post-operative expectations to optimize the outcome of common inguinal hernia repairs.

Varying convalescence recommendations after inguinal hernia repair: a systematic scoping review

PURPOSE

The most recent international guideline on inguinal hernia management recommends a short convalescence after repair. However, surgeons' recommendations may vary. The objective of this study was to give an overview of the current convalescence recommendations in the literature subdivided on the Lichtenstein and laparoscopic inguinal hernia repairs.

METHODS

In this systematic review, three databases were searched in August 2021 to identify studies on inguinal hernia repairs with a statement about postoperative convalescence recommendations. The outcome was convalescence recommendations subdivided on daily activities, light work, heavy lifting, and sport.

RESULTS

In total, 91 studies fulfilled the eligibility criteria, and 50 and 58 studies reported about convalescence recommendations after Lichtenstein and laparoscopic repairs, respectively. Patients were instructed with a wide range of convalescence recommendations. A total of 34 Lichtenstein studies and 35 laparoscopic studies recommended resumption of daily activities as soon as possible. Following Lichtenstein repairs, the patients were instructed to resume light work after median 0 days (interquartile range (IQR) 0-0), heavy lifting after 42 days (IQR 14-42), and sport after 7 days (IQR 0-29). Following laparoscopic procedures, the patients were instructed to resume light work after median 0 days (IQR 0-0), heavy lifting after 14 days (IQR 10-28), and sport after 12 days (IQR 7-23).

CONCLUSION

This study revealed a broad spectrum of convalescence recommendations depending on activity level following inguinal hernia repair, which likely reflects a lack of high-quality evidence within this field.

Evaluation of long-term chronic pain and outcomes for unilateral vs bilateral circular incision transabdominal preperitoneal inguinal hernia repair

Aim

This study has two aims: to evaluate long-term chronic pain and complications after circular incision transabdominal preperitoneal inguinal hernia repair (C-TAPP) and compare outcomes of unilateral and bilateral inguinal hernia cases.

Methods

A postoperative patient questionnaire was used to evaluate pain and complications in 1546 patients who underwent C-TAPP for simple inguinal hernia. Questions concerned satisfaction with surgery, pain at rest, pain at movement, mesh discomfort on a 10-point scale, and complications, such as recurrence. Patients were classified into unilateral (U Group) and bilateral (B Group) groups, and propensity score matching was performed to compare long-term chronic pain and complications.

Results

The questionnaire return rates were 77.5% (1034 cases) and 79.9% (135 cases) in unilateral and bilateral cases. The frequency of moderate-to-severe (≥4 points) pain at rest, pain at movement, and mesh discomfort were 3.2%, 3.6%, and 4.5%, respectively. After propensity score matching, no significant differences in pain at rest (P = .726), at movement (P = .712), or mesh discomfort (P = .981) were detected between the U and B groups. Postoperative complications occurred in 2.1% of all patients, and the recurrence rate was 0.3%. In the post-match comparison, no differences in complications with Clavian-Dindo classification ≥III (U Group 0.7%, B Group 2.1%, P = .622) were detected.

Conclusion

C-TAPP, which focuses on the layered structure, showed acceptable results for long-term chronic pain. Bilateral cases did not have worse pain or complications compared to unilateral cases.

Comparison of laparoscopic transabdominal preperitoneal hernioplasty and laparoscopic iliopubic tract repair for Nyhus type II hernia in women

BACKGROUND

Indirect inguinal hernia with a dilated internal ring but an intact posterior inguinal wall is classified as Nyhus type II. Females have a higher incidence of indirect hernia than direct hernia. The purpose of this study was to evaluate the efficacy of laparoscopic iliopubic tract repair (IPTR) compared with laparoscopic transabdominal preperitoneal (TAPP) hernioplasty in treating women with Nyhus type II hernia.

METHODS

This retrospective study included 318 women aged ≥ 20 years who were treated for Nyhus type II hernia from January 2013 to December 2018. The patients were categorized into two groups in accordance with the operative technique: the TAPP group (33 patients) and the IPTR group (285 patients). In the IPTR group, intraabdominal suturing of the iliopubic tract and transversalis fascia arch was performed without mesh implantation.

RESULTS

The mean operation time was shorter in the IPTR group (17.2 ± 3.9 min) than the TAPP group (20.5 ± 8.1 min, p = 0.028). The postoperative complication rate was higher in the TAPP group than the IPTR group [6.1% (2/33) vs. 0.4% (1/285), respectively; p = 0.001]. Inguinodynia occurred in one patient in the TAPP group and no patients in the IPTR group. The hospital stay did not significantly differ between the two groups. The numeral rating scale pain scores at 1 day and 1 week postoperatively did not significantly differ between the two groups. There was no recurrence in either group.

CONCLUSIONS

Laparoscopic IPTR was safe and feasible for treating Nyhus type II hernia in women.

Predictors of chronic pain after laparoscopic inguinal hernia repair

BACKGROUND

Multiple studies have analyzed predictors for chronic pain after open hernia repair. The purpose of this study is to determine which factors predict the development of chronic pain after a laparoscopic inguinal hernia repair.

METHODS

We identified patients who underwent laparoscopic inguinal hernia repair between 2008 and 2020 at a single institution. Quality of life was measured using the Surgical Outcomes Measurement System and Carolinas Comfort Scale. We categorized patients with chronic pain if their score on Carolinas Comfort Scale was greater than or equal to 3. Multivariable logistic regression analysis was used to identify predictors of chronic pain.

RESULTS

A total of 960 patients met inclusion criteria. Mean age was 59 (± 14, standard deviation) years, 89 (9.3%) of whom were female. Six percent of patients met criteria for chronic pain (Carolinas Comfort Scale ≥3). On multivariable analysis, predictors for chronic pain were age 45 (P < .001), female sex (P = .006), preoperative pain visual analog scale ≥1 (P = .025), prior inguinal hernia repair (P = .045), higher American Society of Anesthesiologists class (P = .041), use of multifilament polyester mesh (P = .0448), and intraoperative placement of a urinary catheter (P = .009).

CONCLUSION

Laparoscopic inguinal hernia repair results in 6.0% of patients experiencing chronic pain. We identified multiple predictors for chronic pain.

Incidence of postoperative complications in transabdominal preperitoneal repair for groin hernia is influenced by poor performance status rather than by old age

AIM

The present study was designed to evaluate the safety and feasibility of transabdominal preperitoneal (TAPP) repair for very old patients with groin hernia and to identify the risk factors predicting perioperative complications.

METHODS

A total of 140 patients treated by TAPP were reviewed retrospectively. They were divided into two groups: patients ≥80 years of age (≥80 years group; n = 26) and those <80 years of age (<80 years group; n = 114). Patient characteristics and surgical outcomes were then statistically compared between the two groups.

RESULTS

Number of patients with any comorbidities was significantly higher in the ≥80 years group than in the <80 years group (96.2% vs 61.4%, P = 0.003). There were no significant differences in surgical outcomes between the two groups. In the univariate analysis of perioperative complications, poor performance status (PS) (P = 0.014), lower hemoglobin level (P = 0.038) and lower albumin level (P = 0.016) were significantly associated with the occurrence of postoperative complications, and multivariate analysis showed that only poor PS was an independent factor (PS 0-2 vs 3-4: P = 0.034, OR 5.192 [95% CI; 1.137 to 23.71]).

CONCLUSIONS

This is the first report to show that the incidence of postoperative complications in TAPP repair for groin hernia is influenced by poor PS rather than old age. TAPP can be a safe surgical procedure for very old patients with a good PS, with benefits that are equal to those in young patients.
