Prolene hernia system versus Lichtenstein repair for inguinal hernia: a meta-analysis

Post operative pain associated with ProGrip mesh hernioplasty: a systematic review and meta-analysis

PURPOSE

Postoperative pain is a common complication following inguinal hernia repair. Progrip mesh is a self-adhesive mesh claimed to reduce postoperative pain compared to traditional mesh types. This meta-analysis aimed to compare postoperative pain, operative time, hospital stay, complications, and recurrence rates between Progrip mesh and other mesh types for inguinal hernia repair.

METHODS

A systematic search was conducted to identify randomized controlled trials comparing Progrip mesh with other mesh types for inguinal hernia repair. Primary outcome was postoperative pain assessed using the Visual Analogue Scale (VAS). Secondary outcomes included operative time, hospital stay, complications, and recurrence rates. Meta-analyses were performed to calculate pooled effect estimates with heterogeneity assessment.

RESULTS

Twenty-one studies involving 3827 participants were included. Progrip mesh was associated with significantly lower postoperative pain at 6 h (MD = - 1.21, p = 0.05), 1st day (MD = - 0.50, p = 0.03), 7th day (MD = - 0.38, p = 0.01), 2 weeks (MD = - 0.32, p = 0.007), 3 months (MD = - 0.48, p < 0.00001), and 6 months (MD = - 0.43, p < 0.0001) postoperatively compared to other mesh types. However, at 3 days, 1 month, and 1 year, the differences in pain scores were not statistically significant. Operative time was significantly shorter in the Progrip mesh group (MD = - 9.65 min, p < 0.00001). Recurrence rates were significantly higher in the Progrip mesh group (RR = 1.62, p = 0.02). No significant differences were observed in hospital stay (MD = - 0.32, p = 0.22) or postoperative complications (RR = 0.93, p = 0.59).

CONCLUSION

Progrip mesh demonstrated a significant reduction in operative time and postoperative pain compared to traditional mesh types for inguinal hernia repair. Though, it was associated with higher recurrence rates. There were no significant differences in other outcomes. Further high-quality studies with longer follow-up are needed to assess the long-term effects of Progrip mesh.

High peritoneal incision approach in endoscopic transabdominal preperitoneal patch plasty (TAPP) for inguinal hernia after radical prostatectomy

BACKGROUND

Inguinal hernia develops as one of the common complications after robotic or laparoscopic radical prostatectomy (RP). Transabdominal preperitoneal patch plasty (TAPP) for an inguinal hernia after RP is difficult to perform due to postoperative severe adhesions in the preperitoneal cavity. We have introduced a high peritoneal incision approach (HPIA) in TAPP for inguinal hernia patients in whom peritoneal dissection is difficult due to severe adhesions after RP. We evaluate the safety and efficacy of TAPP with a HPIA for patients with an inguinal hernia after robot-assisted RP (RARP).

METHODS

Patients characteristics and surgical outcome were evaluated by a retrospective analysis.

RESULTS

From January 2014 to December 2017, 21 consecutive patients underwent TAPP for an inguinal hernia after RARP. Twenty-four lesions were the type 3b and three were type 3a according to the Nyhus classification. A circular incision TAPP was performed for 10 hernia lesions in eight patients and TAPP with HPIA was utilized for 17 lesions in 13 patients. The mean operation time for the unilateral hernia in the HPIA (137.8 ± 20.7 min) was significantly shorter than that (182.2 ± 42.0 min) in the circular incision TAPP (p = .038). The HPIA was complete in all patients, while the circular incision TAPP was converted to intraperitoneal onlay mesh (IPOM)intraperitoneal onlay mesh in five patients (55.6%, p = .008) due to dense adhesions with difficult dissection. No recurrent was observed after follow-up period of 48 months in both groups.

CONCLUSIONS

The TAPP with HPIA is feasible and a safe and reliable treatment of choice in patients with an inguinal hernia after RARP.

Surgical Technique and Chronic Postoperative Inguinal Pain in Patients Undergoing Open Inguinal Hernioplasty in Portugal: A Prospective Multicentric Cohort Study

INTRODUCTION

Evidence about the advantage of Lichtenstein's repair, the guidelines' recommended technique, is scarce regarding postoperative chronic inguinal pain (CPIP). The primary aim of this study was to compare CPIP in patients undergoing Lichtenstein versus other techniques.

METHODS

Prospective multicentric cohort study including consecutive adults undergoing elective inguinal hernia repair in Portuguese hospitals (October - December 2019). Laparoscopic and mesh-free hernia repairs were excluded. The primary outcome was postoperative pain at three months, defined as a score of ≥ 3/10 in the European Hernia Society Quality of Life score pain domain. The secondary outcome was 30-day postoperative complications.

RESULTS

Eight hundred and sixty-nine patients from 33 hospitals were included. Most were men (90.4%) and had unilateral hernias (88.6%). Overall, 53.6% (466/869) underwent Lichtenstein's repair, and 46.4% (403/869) were treated with other techniques, of which 83.9% (338/403) were plug and patch. The overall rate of CPIP was 16.6% and 12.2% of patients had surgical complications. The unadjusted risk was similar for CPIP (OR 0.76, p = 0.166, CI 0.51 - 1.12) and postoperative complications (OR 1.06, p = 0.801, CI 0.69 - 1.60) between Lichtenstein and other techniques. After adjustment, the risk was also similar for CPIP (OR 0.83, p = 0.455, CI 0.51 - 1.34) and postoperative complications (OR 1.14, p = 0.584, CI 0.71 - 1.84).

CONCLUSION

The Lichtenstein technique was not associated with lower CPIP and showed comparable surgical complications. Further investigation as- sessing long term outcomes is necessary to fully assess the benefits of the Lichtenstein technique regarding CPIP.

Prolene Hernia System Maximum Repair: A New Concept in Sports Hernia Surgery

OBJECTIVE

To describe and present the clinical results of a new surgical treatment for sports hernia.

DESIGN

Retrospective cohort study.

SETTING

Tertiary hospital.

PATIENTS

Athletes who underwent sports hernia repair using the proposed technique between July 2006 and June 2020.

INTERVENTION

The surgery consists of a combination of a mini-open incision and preperitoneal placement of a three-dimensional bilayer permanent mesh (PHS).

MAIN OUTCOME MEASURES

The main clinical outcomes of the procedure were reviewed, including incidence of complications, long-term results, and recurrence rate.

RESULTS

Ninety-two sports hernia repairs were performed on 87 patients (79 male and 8 female patients, median age 30.2 ± 7.8 years). No intraoperative complications were observed. The mean follow-up was 15 months. Seventy-seven patients (88.5%) successfully resumed preinjury physical activities within 8 weeks; 80 patients (91.9%) within 12 weeks; and 83 (95.4%) within 6 months (median time of 10 weeks). Only one patient reported recurrence of symptoms.

CONCLUSION

Mini-open incision PHS repair seems to be a safe and effective method for treatment of sports hernia, resulting in early return to physical activities, with few complications, and low recurrence rate.

Inguinal hernia repairs performed for recurrence in Spain: population-based study of 16 years and 1,302,788 patients

PURPOSE

The objective of this study was to assess data on inguinal hernia repairs (IHR) performed for recurrence over a 16 year period (2004-2019) in Spain.

METHODS

A retrospective cohort study of 1,302,788 patients who underwent IHR from January 2004 to December 2019 was conducted. Data were extracted from the Spanish Minimum Basic Data Set (MBDS) of the Health Ministry database. The primary objective was to analyse the proportion of IHR performed by recurrence. As secondary objectives, we evaluated factors related to recurrent hernia (analysed by univariate analysis and multivariable logistic regression analysis) and trends in the recurrent case rate over the 16 year period.

RESULTS

We identified 95,025 patients (7.3% of all IHR) who underwent surgery for recurrent inguinal hernia. Patients undergoing recurrent IHR were more likely to be male (OR 1.687, 95% CI 1.645-1.730), elderly (age > 74 years), and more complicated when they arrived in the operating room (gangrene OR 3.951, 95% CI 3.734-4.180; occlusion OR 1.905, 95% CI 1.853-1.960), and thus had more surgical site occurrences and related mortality. The proportion of IHR performed for recurrence has been dropping over the years (8.7% in 2004 vs. 6.5% in 2019, p < 0.005).

CONCLUSION

The rate of recurrent IHR in Spain (2004-2019) is 7.3%. Recurrent IHR correlates to emergent and complicated surgery and thus to a worst outcome. The trend of this 16 year period is of decreasing operated recurrent inguinal hernia. This is good news even though the improvement is slight and certainly insufficient. Establishing and optimising the rate of hernia recurrence is important for patients and for the health-care system.

Vasocutaneous fistula formation and repair following inguinal hernia repair in a rhesus monkey (Macaca mulatta)

A 6‐year‐old adult male rhesus macaque (Macaca mulatta) developed a vasocutaneous fistula following an anatomic inguinal hernia repair years earlier. The vasocutaneous fistula was surgically repaired, the vas deferens was ligated, and the wound was closed in layers with non‐overlapping suture lines with no further adverse sequalae of events.

Modified Halsted's operation for inguinal hernia repair: A new technique

Background

Inguinal hernia is a frequent problem presented to surgical clinic in Iraq. Surgical treatment options for inguinal hernia are numerous, selecting the appropriate method or technique depends on different factors.

Aim of study

To find a new technique for open inguinal hernia repair with no recurrence even in recurrent cases, without major complications during or after surgery, and can be used even by new surgeons with little experience.

Patients & methods

A retrospective cross sectional study conducted in the Medical City teaching hospital and Private Hospitals in Baghdad, during the period from January 1, 2000, to December 30, 2016 on convenient sample of 408 Iraqi patients with inguinal hernia. The patients were treated by modified Halsted's technique by open surgery applying polypropylene mesh. The patients were followed up through frequent visits and phone calls to assess the recurrence and complications.

Results

No recurrence of inguinal hernia was reported after 5-10 years follow up, while 94.9% of patients reported postoperative complications commonly oedema of spermatic cord. There was a highly significant association between male gender hernia patients and post Modified Halsted operation complications (p < 0.001). A highly significant association was observed between direct hernia and post Modified Halsted operation complications (p < 0.001). The significant risk factors related to complications were anemia and collagen disease.

Conclusions

The modified Halsted's operation for inguinal hernia repair is effective in treatment of inguinal hernia with low recurrence and complications rate.

Inguinal hernia – epidemiology, risk factors, treatment methods (literature review)

Inguinal hernias (IH) are widespread in the human population and occur in 27–43 % of men and 3–6 % of women. Many risk factors for IH have been overestimated in the last decade: male gender is considered the leading factor (the ratio between men and women is approximately 1:7), less significant factors are heredity (most significant for women), physical activity (more significant for men), age (peak prevalence of IH occurs at 5 years and 70–80 years), congenital or acquired connective tissue dysplasia, history of prostatectomy, low body mass index.Hernioplasty with the use of synthetic mesh prostheses remains the most popular technique for surgical correction of IH. Performing non-prosthetic hernioplasty is only recommended if mesh prostheses are not available, for example in poor countries. In open hernioplasty using mesh prostheses, different methods are used today: Plug & Patch, Prolene Hernia System, Parietene Progrip, sutureless plastic according to Trabucco, Stoppa, preperitoneal techniques TIPP (trans-inguinal pre-peritoneal), TREPP (transrectus pre-peritoneal), TEP (total extraperitoneal), however, none of them showed significant advantages over the gold standard of open hernioplasty – tensionfree repair according to Liechtenstein.Laparoscopic IH correction is represented by the TAPP (transabdominal preperitoneal) technique, performed through the abdominal cavity, and TEP (total extraperitoneal) – extraperitoneal prosthetic hernioplasty. None of them has a significant advantage in the treatment of IH; therefore, when choosing a treatment method, the surgeon should be guided by the cost of the operation and the level of proficiency in one or another hernioplasty technique.
