Impact of previous mesh hernia repair on the performance of open radical prostatectomy - complications and functional outcome

The impact of previous inguinal mesh hernioplasty on oncological and patient-reported outcomes following radical prostatectomy

BACKGROUND

The impact of previous inguinal mesh hernioplasty (MH) with non-resorbable mesh prostheses on surgical performance of radical prostatectomy (RP) has been controversially discussed, with unknown impact of MH on oncologic outcomes and health-related quality of life (HRQOL) following RP. We therefore aimed to assess the influence of previous MH on metastasis-free survival (MFS), biochemical recurrence-free survival (BRFS), and HRQOL following RP.

METHODS

We identified 344 patients with previous MH prior RP within our prospectively assessed institutional database of 6275 patients treated with RP for PC (2008-2019). A 1:3 propensity-score matched analysis of 1345 men (n = 319 previous MH, n = 1026 no previous MH) was conducted. Primary endpoint was MFS and secondary endpoints were BRFS and HRQOL (based on EORTC QLQ-C30). Binary logistic regression, Kaplan-Meier, and Cox regression models tested the effect of previous MH on MFS, BRFS, and HRQOL (p < 0.05).

RESULTS

Median follow-up was 47 months. Patients with previous MH had significantly lower 5-year MFS (72% vs. 85%, p < 0.001) and 5-year BRFS estimates (43% vs. 57%, p < 0.001). In multivariate analysis, previous MH was confirmed as an independent predictor for impaired MFS (hazard ratio [HR]: 3.772, 95% CI 1.12-12.64, p = 0.031) and BRFS (HR: 1.862, 95% CI: 1.22-2.85, p = 0.004). These results held true if stratified for surgical approach or limited to patients with successful PLND. We found significantly shorter median time to continence recovery for patients without previous MH (p = 0.001) without significant differences in total continence recovery rates, erectile function recovery, and HRQOL.

CONCLUSIONS

Our findings show an impaired oncologic outcome for patients with previous MH following RP with no significant differences regarding continence recovery, erectile function recovery, and general HRQOL.

Laparoscopic hernia repair: nonfixation mesh is feasibly?

BACKGROUND

Several surgical techniques have been developed over the past years, and total extraperitoneal and transabdominal preperitoneal inguinal hernia repair are the endoscopic techniques that are most commonly used.

AIM

To describe and discuss Dulucq's technique and the modifications of using 3-D mesh in total extraperitoneal inguinal hernia repair.

METHODS

Patients who underwent an elective inguinal hernia repair were enrolled prospectively in this study. Operative and postoperative course were studied.

RESULTS

A total of 261 hernia repairs were included in the study. The hernias were repaired by total extraperitoneal technique; two hernias (0.75%) were converted to open anterior Liechtenstein technique. Mean operative time was 43.38 min in unilateral hernia and 53.36 min in bilateral hernia. Most of the patients (95%) were discharged at the same day of the surgery. The overall postoperative morbidity rate was 5.7%. The incidence of recurrence rate was 0.0% in median follow-up period of 26 months.

CONCLUSION

Total extraperitoneal hernioplasty is a very effective and safe procedure in the hands of experienced surgeons with specific training. It is an interesting option in bilateral and recurrent hernia as it obtains satisfactory results in terms of postoperative pain and morbidity.

Case-matched analysis of outcome after open retropubic radical prostatectomy in patients with previous preperitoneal inguinal hernia repair

Background

The impact of preperitoneal mesh repair for inguinal hernia on future pelvic surgery is debatable. This retrospective study investigated the impact of previous preperitoneal inguinal hernia repair (PIHR) on outcome after open retropubic radical prostatectomy (RRP) for prostatic cancer.

Methods

Patients who had open RRP and who had previously undergone PIHR were identified. They were compared with a control group of patients matched for age, body mass index and tumour risk profile who had no history of inguinal hernia repair. Outcome measures included intraoperative data, histopathology and results at follow-up.

Results

Sixty patients who had undergone open RRP after a previous PIHR were compared with 60 control patients. Operations lasted longer in the PIHR group (median (interquartile range, i.q.r.) 100 (90–120) versus 90 (85–100) min respectively; P &lt; 0·001) and the operation was assessed as more difficult by the surgeon (P = 0·022). Hospital stay was longer for patients who had undergone PIHR (median (i.q.r.) 7 (6–9) versus 6 (5–7) days; P = 0·012) and urinary catheterization was prolonged (13 (11–14) versus 11 (11–12) days; P = 0·006). Among patients with intermediate- and high-risk disease, fewer lymph nodes were excised in the PIHR group than in the control group (median (i.q.r.) 2 (0–7) versus 8 (5–12) nodes; P &lt; 0·001).

Conclusion

Open RRP for prostatic cancer was more difficult to perform after previous PIHR, and was associated with a longer hospital stay and less adequate lymphadenectomy for intermediate- and high-risk prostatic cancer.
