Postoperative pain and quality of life after laparoscopic and open inguinal hernia repair: results of a prospective randomized trial

Assessment of Surgical and Quality-of-Life Outcomes Between Laparoscopic Versus Open Inguinal Hernia Repair in Geriatric Patients

Introduction: Inguinal hernia repair is a common surgery, especially in the elderly population. However, the decision to perform surgery in elderly patients can be challenging due to higher complication rates. Laparoscopic inguinal hernia surgery is less commonly used in the elderly population despite its advantages. In this study, we aimed to investigate the safety and advantages of laparoscopic inguinal hernia surgery in elderly patients. Methods: We retrospectively compared the preoperative and postoperative (PO) data and Short Form-36 (SF-36) forms of elderly patients who underwent laparoscopic transabdominal preperitoneal and open inguinal hernia surgery. The primary outcomes were PO pain scores and complication rates. Results: A total of 79 patients with an age range between 65 and 86 years, who presented with inguinal hernias to Cekirge State Hospital's General Surgery Department between January 2017 and November 2019, were included. Seventy-nine patients underwent laparoscopic transabdominal preperitoneal technique and Lichtenstein hernia repair. The laparoscopic group had a lower rate of PO complications and less analgesic medication consumption and usage time compared with the open group. Furthermore, compared with the open group, the laparoscopic group had lower PO pain scores and higher SF-36 scores for physical function, physical role, pain, and general health at the 30th and 90th days after surgery. Conclusion: Our study suggests that laparoscopic inguinal hernia surgery can be safely performed in elderly patients with lower complication rates and faster recovery times compared with open surgery. The advantages of laparoscopic surgery, such as lower PO pain scores and faster recovery times, were also observed in elderly patients.

Return to Work in Patients With Unilateral Inguinal Hernia Surgery: A Comparative Study Between Laparoscopic Transabdominal Preperitoneal Approach and Lichtenstein Tension-Free Mesh Repair

Objective The objective of this prospective cohort study was to compare the time to return to work between patients who underwent laparoscopic transabdominal preperitoneal (TAPP) hernia repair and those who underwent Lichtenstein tension-free hernia repair with mesh for unilateral inguinal hernia. Methodology Patients were registered for unilateral inguinal hernia review at Aga Khan University Hospital, Karachi, Pakistan, from May 2016 to April 2017 and followed till April 2020. All patients aged 16-65 planned for unilateral transabdominal preperitoneal hernia repair or Lichtenstein tension-free hernia mesh repair were included. Patients with bilateral inguinal hernia repair, limited activity, or above retirement age were excluded. A non-probability consecutive sampling technique was implemented, and patients were divided into two cohort groups: Group A underwent laparoscopic transabdominal preperitoneal hernia repair, while Group B underwent Lichtenstein tension-free mesh repair. Patients were followed up at one week to inquire about the resumption of activities and then at one and three years for recurrence. Results Sixty-four patients met the inclusion criteria; three patients opted out of research, and 61 patients agreed to participate; one patient was excluded due to the conversion of the procedure. The remaining 30 in Group A and 30 in Group B were followed for the study period. The mean time to return to work in Group A was 5.33 ± 4.46 days; in Group B, it was 6.83 ± 4.58 days, with a p-value of 0.657. One recurrence was observed at three years in Group A. Conclusion Although the time to return to work at our hospital was slightly shorter in laparoscopic hernia repair than in the open technique, the results were not statistically significant. In addition, there was no significant difference in hernia recurrence at the one-year follow-up between laparoscopic transabdominal preperitoneal hernia repair and Lichtenstein tension-free hernia mesh repair for unilateral inguinal hernia.

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.

Fast Early Recovery After Transabdominal Preperitoneal Repair in Athletes with Sportsman's Groin: A Prospective Clinical Cohort Study

BACKGROUND

Current literature on chronic groin pain suggests that laparoscopic mesh repair on athletes enables a faster recovery and subsequent return to unrestricted athletic activities. The aim of this study was to evaluate the role of transabdominal preperitoneal (TAPP) mesh repair in athletes resistant to conservative therapy.

METHODS

A multidisciplinary approach with tailored physiotherapy. Thirty-nine professional athletes with chronic groin pain were referred to surgery at a single clinic. A full assessment was carried out on each, including medical history, physical examination, dynamic ultrasound, and pelvic magnetic resonance imaging. TAPP repair was performed using a polypropylene mesh and fibrin glue fixation on 30 athletes who had exhibited typical symptoms, shown resistance to conservative therapy, not benefited from accompanying physiotherapy, and had ceased training in the 3 to 6 months prior. The outcome measures were early postoperative recovery of 6 weeks and full resumption of athletic activities.

RESULTS

Mean duration of symptoms from onset to surgical repair was 7 months. Conservative treatment had improved symptoms temporarily or to some extent in 7 athletes, while 2 ceased competing altogether. Twenty-three athletes exhibited unilateral and 16 bilateral groin pain. Laparoscopy confirmed posterior wall deficiency in 24 and true inguinal hernia in 6 athletes. Mild scrotal hematoma occurred in 2 athletes postoperatively; all were discharged within 24 hours of surgery. Twenty-one (70%) returned to sports activities after 6 weeks of convalescence. Persistent mild pain was experienced by 5 athletes postoperatively for up to 1 year, yet did not interfere with normal daily activity. Twenty-five participants (85%) reported full satisfaction with the procedure 1 year after treatment; all returned to the same or even higher level of athletic performance.

CONCLUSION

The study confirms that the endoscopic placement of retropubic mesh is an efficient, safe, and minimally invasive treatment that enables fast early recovery.

Laparoscopic Totally Extraperitoneal Groin Hernia Repair and Quality of Life at 2-Year Follow-Up

BACKGROUND

The lack of long-term data on quality of life after groin hernia repair presents a challenge in setting patients' postoperative expectations. This study aimed to describe quality of life outcomes after laparoscopic totally extraperitoneal groin hernia repair with a minimum of 2 years follow-up.

STUDY DESIGN

We prospectively evaluated 293 patients who had laparoscopic totally extraperitoneal groin hernia repair in an IRB-approved study. The Short-Form 36-item Health Survey (version 2), Surgical Outcomes Measurement System, and Carolinas Comfort Scale were administered pre- and postoperatively. Pairwise comparisons using nonparametric Wilcoxon signed rank test were made between time points.

RESULTS

Mean patient age was 56 ± 15 years and 93% were male; 80% of patients presented with painful hernias and 15% of hernias were recurrent. Mean operative time was 43 ± 16 minutes. No operative complications occurred. Mean duration of narcotic pain medication use was 2.5 ± 3.4 days, and daily activities were resumed and return to work occurred 5.4 ± 4.4 days and 5.4 ± 3.9 days post operation, respectively. Recurrence rate was 2%. The Short-Form 36-item Health Survey outcomes improved from baseline for domains of Physical Functioning, Role Limitations due to Physical Health, and Pain at 2 years post operation; Surgical Outcomes Measurement System outcomes improved for domains of Pain Impact on Quality of Life, Body Image, and Patient Satisfaction (p ≤ 0.05). The percentage of patients reporting no or mild but not bothersome symptoms on the Carolinas Comfort Scale at 2 years post operation for sensation of mesh, pain, and movement limitations were 98%, 95%, and 97%, respectively.

CONCLUSIONS

Measuring both general and procedure-specific quality of life, patients' perceptions of health status improved significantly 2 years after laparoscopic totally extraperitoneal groin hernia repair.

Early pain after laparoscopic inguinal hernia repair. A qualitative systematic review

BACKGROUND

Early post-operative pain after laparoscopic groin hernia repair may, as in other laparoscopic operations, have its own individual pain pattern and patient-related predictors of early pain. The purpose of this review was to characterise pain within the first post-operative week after transabdominal pre-peritoneal repair (TAPP) and total extraperitoneal repair (TEP), and to identify patient-related predictors of early pain.

METHODS

A qualitative systematic review was conducted. Pubmed, Embase, CINAHL, and the Cochrane database were searched for studies on early pain (first week) after TAPP or TEP.

RESULTS

We included 71 eligible studies with 14,023 patients. Post-operative pain is most severe on day 0 and mainly on a level of 13-58 mm on a visual analogue scale and decreases to low levels on day 3. There seems to be no difference in pain intensity and duration when TEP and TAPP are compared. Deep abdominal pain (i.e. groin pain/visceral pain) dominates over superficial pain (i.e. somatic pain) and shoulder pain (i.e. referred pain) after TAPP. Predictors of early pain are young age and pre-operative high pain response to experimental heat stimulation. Furthermore, evidence supported early pain intensity as a predictive risk factor of chronic pain after laparoscopic groin hernia repair.

CONCLUSION

Early pain within the first week after TAPP and TEP is most severe on the first post-operative day, and the pain pattern is dominated by deep abdominal pain. Early post-operative pain is most intense in younger patients and can be predicted by pre-operative high pain response to experimental heat stimulation.

Community-based appraisal of laparoscopic abdominal surgery in Japan

BACKGROUND

Despite the prevalence of laparoscopic surgery (LS), community-based appraisal of its benefit over open surgery (OS) has not been performed. This can be measured by increased total charge (TC) spent and decreased length of stay (LOS), which are indicative of greater resource use and opportunistic cost reduction. We prioritized the value of LS for eight abdominal procedures.

MATERIALS AND METHODS

We used a Japanese administrative database for the 6 mo leading up to December 2007. Study procedures were appendectomy, cholecystectomy, choledocholithotomy, herniorrhaphy, colectomy, partial or total gastrectomy, and small bowel resection (SBR) in adults. We analyzed patient demographics, mortality, comorbidity, complications, use of chemotherapy or postoperative pain control, hospital teaching status, postoperative LOS, and TCs. The impact of LS was determined using multivariate analysis on the propensity-score-matched cohorts of LS and OS.

RESULTS

Herniorrhaphy was most frequently performed (24,088 cases), whereas SBR was performed least (3404). LS was performed most often in cholecystectomy (81%) and least in herniorrhaphy (3.7%). LS did not increase complications in any procedure. Laparoscopic cholecystectomy and SBR were associated with shorter LOS and lower TC, whereas laparoscopic herniorrhaphy increased LOS and TC. Laparoscopic appendectomy and partial gastrectomy reduced LOS and increased TC.

CONCLUSIONS

LS safety was confirmed. Laparoscopic cholecystectomy or SBR might have advantages, whereas laparoscopic was no better than open herniorrhaphy and might be decided by patient's preference. Considering the variation in the decremental opportunistic cost produced by incremental medical expenses observed among the procedures, policymakers should determine an appropriate reimbursement schedule.

The preperitoneal memory-ring patch for inguinal hernia: a prospective multicentric feasibility study

PURPOSE

To evaluate the feasibility, the reproducibility, the safety and the efficacy of a recently introduced preperitoneal memory-ring patch (Polysoft, Davol Inc., C.R. Bard Inc., Crawley, UK) by a prospective multicentric observational study.

METHODS

We performed 235 unilateral groin hernia repairs in 200 consecutive patients during a 12-month period. Patients were operated by three different surgeons in two different centres. Pre- and intraoperative data, as well as postoperative complications, were prospectively recorded.

RESULTS

Two hundred patients, with a mean age of 55.4 years, were operated for primary or recurrent unilateral groin hernias. The mean operation time for unilateral hernia repair was 22 min (range 14-37 min). Seventy-one patients (35.5%) were operated in an ambulatory setting. Considering pain scores, we observed a preoperative visual analogue scale (VAS) score of 1.4 (range 0-3.7). After 24 h, 3 weeks and 6 months, VAS was 4.2 (0.5-6.9), 1.7 (0-2.0) and 0.1 (0-1.5), respectively. The follow-up was more than 18 months in all patients (range 19-31 months). In total, three patients were diagnosed with a recurrence and were reoperated by an anterior Lichtenstein repair with large-pore mesh.

CONCLUSION

This transinguinal minimally invasive preperitoneal mesh repair is reproducible, easy to perform and safe with acceptable mid-term results. These elements, together with a minimal superficial dissection in the inguinal canal, preperitoneal mesh placement and the absence of fixation, are possible elements to reduce acute and chronic postoperative pain compared to other open and also laparoscopic techniques that have to be proven in larger (randomised) trials.

Recurrence and complications after laparoscopic versus open inguinal hernia repair: results of a prospective randomized multicenter trial

BACKGROUND

The aim of this prospective randomized multicenter trial was to evaluate the recurrence rates and complications of open versus laparoscopic repairs of inguinal hernias.

METHODS

Patients with primary unilateral inguinal hernias were randomized to Shouldice repair, Bassini operation, tension-free hernioplasty (Lichtenstein repair), laparoscopic transabdominal extraperitoneal hernioplasty (TEP), or laparoscopic transabdominal preperitoneal hernioplasty (TAPP). The primary outcome parameter was the rate of recurrence at 3 years. The secondary outcome was the rate of intraoperative, perioperative, and long-term complications. Follow-up comprised of clinical examination after 1, 2, and 3 years.

RESULTS

Three hundred and sixty-five patients were randomly assigned to one of the five procedures. The intention-to-treat analysis showed that the cumulative 3-year recurrence rate was 3.4% in the Bassini group, 4.7% in the Shouldice group, 0% in the Lichtenstein group, 4.7% in the TAPP group, and 5.9% in the TEP group (p = 0.48). Comparing open (Bassini, Shouldice, Lichtenstein) versus laparoscopic (TAPP, TEP) techniques (p = 0.29) and comparing the use of mesh prostheses (Lichtenstein, TAPP, TEP) versus suturing techniques (Bassini, Shouldice) (p = 0.74) showed no significance in the rate of recurrence. The rates of intraoperative (p = 0.15), perioperative (p = 0.09), and long-term complications (p = 0.13) were without significance between the five groups. Comparing mesh techniques (Lichtenstein, TAPP, TEP) versus suturing techniques (Bassini, Shouldice) showed no significance in the rate of complications. The per-protocol analysis for the comparison of mesh (Lichtenstein, TAPP, TEP) versus suturing (Bassini, Shouldice) techniques revealed that recurrences (p = 0.74), intraoperative (p = 0.64), perioperative (p = 0.27), and long-term complications (p = 0.91) were evenly distributed.

CONCLUSIONS

In this multicenter study, no significant difference in the recurrence rate and complications between laparoscopic and open methods of hernia repair was revealed.

Treatment for persistent chronic neuralgia after inguinal hernioplasty

Following an inguinal hernia repair with open or laparoscopic technique, 1-15% of patients show persistent neuralgia, a severe, potentially debilitating, complication. Several therapeutic procedures have been proposed, but consensus regarding choice of treatment has not yet been achieved. We performed a prospective study on 32 such cases. Patients underwent anaesthetic infiltration to identify, when possible, the involved nerve, and we then carried out a step-by-step therapeutic protocol. In the initial phase, patients were treated with oral analgesic and afterwards with repeated infiltrations of anaesthetic and cortisone. Surgery was reserved for patients not responding to the infiltrations, though with no good success. The authors believe that noninvasive methods are to be preferred, whereas neurectomy interventions should be reserved for selected cases.
