Outcome of inguinal hernia repair after previous radical prostatectomy: a registry-based analysis with 12,465 patients

Is previous radical prostatectomy an adversity for laparoscopic total extraperitoneal approach for inguinal hernia repair? A propensity score case matched study

INTRODUCTION

Although laparoscopic total extraperitoneal (TEP) procedure has gained wide acceptance for inguinal hernia repair, there is still debate on the optimal technique in patients with a history of previous radical prostatectomy (RP). We aimed to evaluate the feasibility and safety of laparoscopic TEP in patients with a previous history of RP using a propensity score case-match analysis.

METHODS

This study included male patients undergoing laparoscopic TEP repair between 2013 and 2024. According to the RP status, patients were case-matched based on age, BMI, ASA score, site of hernia and the year of surgery. A total of 162 patients were matched in a 1:5 ratio. The RP and non-RP groups were compared with respect to perioperative outcomes.

RESULTS

The RP and non-RP group included 27 and 135 patients, respectively. The rate ofconversion to transabdominal preperitoneal repair (11.1%) or open surgery (14.8%) was significantly higher in the RP group (p<0.001). The RP group had longer operative times (160±57 vs. 94±38, p<0.001). The postoperative complication rates (7.4% vs. 6%), postoperative pain scores, length of stay (1.6±0.9 vs 1.2±0.9 days), time to return to daily life (2.9±1.8 vs 2.6±3.0 days), readmission (3.7% vs 0.7%), long-lasting pain (14.8% vs. 11.8%) and recurrence (0% vs 3.2%) were similar in both groups (p>0.05).

CONCLUSION

Laparoscopic TEP inguinal hernia repair in patients with a history of RP is feasible and safe with a similar morbidity profile but an increased conversion rate and operative time compared to those with no history of RP.

Open and minimally invasive inguinal hernia repair for patients with previous prostatectomy: a systematic review and proportional meta-analysis

BACKGROUND

Minimally invasive surgery (MIS) for patients undergoing inguinal hernia repair (IHR) after prostatectomy has been considered a challenging procedure due to the presence of scar tissue and adhesions. We aimed to compare the outcomes of open and MIS IHR outcomes in post-prostatectomy patients through a systematic review and proportional meta-analysis.

MATERIAL & METHODS

PubMed/MEDLINE, Embase, Cochrane, and Web of Science were searched for studies on open and MIS IHR after prostatectomy. Outcomes such as recurrence, complications, seroma, hematoma, SSI, and conversion rates were analyzed, with subgroup analyses conducted for open, TEP, and TAPP procedures.

RESULTS

Among 402 screened studies, 18 met the inclusion criteria, covering 8,668 open IHR (64.6%) and 4,761 MIS IHR (35.4%) patients. The rate per 100 events for intraoperative complications was 0.19 (95% CI [0.00; 0.76]; I2 = 71%;), 5.22 per 100 for seroma (95% CI [2.86; 9.34]; I2 = 92%), 0.83 per 100 for SSI (95% CI [0.39; 1.75]; I2 = 48%), 3.16 per 100 for hematoma (95% CI [1.16; 8.31]; I2 = 84%), 3.02 per 100 patients for chronic pain (95% CI [2.53; 3.62]; I2 = 13%), and 0.02 per 100 for recurrence (95% CI [0; 0.16]; I2 = 10%). The conversion rate for MIS was 1.66 per 100 (95% CI [0.89; 3.06]; I2 = 0%). Subgroup analysis revealed no significant difference between TEP and TAPP in intraoperative complications (p = 0.70), but a lower seroma rate in TAPP compared to TEP (5.29 vs. 20 per 100; P = 0.01). MIS had significant reduction in SSI (0.08 vs. 0.34 per 100; P < 0.01), hematoma (1.29 vs. 17.86; p < 0.01), and recurrence (0.08 vs. 0.37; p = 0.04) compared to open, with no difference in seroma rates. Funnel plots revealed no evidence of publication bias.

CONCLUSIONS

In experienced hands, MIS IHR is a safe and effective option for post-prostatectomy patients, with lower complication rates compared to open IHR, although high-quality comparative studies are needed to establish definitive conclusions.

Is previous radical prostatectomy a contraindication to minimally invasive inguinal hernia repair? A contemporary meta-analysis

INTRODUCTION

Traditionally, radical prostatectomy (RP) has been considered a contraindication to minimally invasive inguinal hernia repair. Purpose of this systematic review was to examine the current evidence and outcomes of minimally invasive inguinal hernia repair after RP.

MATERIALS AND METHODS

Web of Science, PubMed, and EMBASE data sets were consulted. Laparoscopic transabdominal preperitoneal repair (TAPP), robotic TAPP (r-TAPP), and totally extraperitoneal (TEP) repair were included.

RESULTS

Overall, 4655 patients (16 studies) undergoing TAPP, r-TAPP, and TEP inguinal hernia repair after RP were included. The age of the patients ranged from 35 to 85 years. Open (49.1%), laparoscopic (7.4%), and robotic (43.5%) RP were described. Primary unilateral hernia repair was detailed in 96.3% of patients while 2.8% of patients were operated for recurrence. The pooled prevalence of intraoperative complication was 0.7% (95% CI 0.2-3.4%). Bladder injury and epigastric vessels bleeding were reported. The pooled prevalence of conversion to open was 0.8% (95% CI 0.3-1.7%). The estimated pooled prevalence of seroma, hematoma, and surgical site infection was 3.2% (95% CI 1.9-5.9%), 1.7% (95% CI 0.9-3.1%), and 0.3% (95% CI = 0.1-0.9%), respectively. The median follow-up was 18 months (range 8-48). The pooled prevalence of hernia recurrence and chronic pain were 1.1% (95% CI 0.1-3.1%) and 1.9% (95% CI 0.9-4.1%), respectively.

CONCLUSIONS

Minimally invasive inguinal hernia repair seems feasible, safe, and effective for the treatment of inguinal hernia after RP. Prostatectomy should not be necessarily considered a contraindication to minimally invasive inguinal hernia repair.

Is previous prostatectomy a risk factor for postoperative complications following minimally invasive inguinal hernia repair? A systematic review and meta-analysis

AIM

The literature indicates that patients with prior pelvic surgery, particularly radical prostatectomy, pose challenges in minimally invasive inguinal hernia repair (IHR). However, there is no conclusive evidence regarding the impact of pelvic surgery on postoperative complications. To address this gap, we conducted a systematic review and meta-analysis to evaluate the influence of previous prostatectomy in men undergoing MIS IHR.

MATERIALS AND METHODS

We searched Cochrane Central, Scopus, SciELO, Lilacs, and PubMed/MEDLINE for studies comparing men undergoing MIS IHR after prostatectomy with men without previous pelvic surgery. Key outcomes evaluated included recurrence, overall postoperative complications, seroma, hematoma, surgical site infection (SSI), conversion rates, and operative time.

RESULTS

Out of 402 screened studies, 9 met the inclusion criteria. Among the included studies, three analyzed totally extraperitoneal (TEP) technique, while four analyzed transabdominal preperitoneal (TAPP) and two presented both techniques together. The analysis comprised 189,183 patients, of which 4551 (2.4%) had a history of prostatectomy. The analysis revealed that post-prostatectomy patients presented higher postoperative complications (3.7% vs. 1.9%; RR 1.9; 95% CI [1.23; 2.94]; P = 0.004) and seroma (1.6% vs. 0.9%; RR 1.58; 95% CI [1.23; 2.04]; P < 0.001) following MIS IHR. Additionally, patients with a previous prostatectomy presented an increased operative time (MD 21.25 min; 95% CI [19.1; 23.4]; P < 0.001). No significant differences were observed in recurrence (0.98% vs. 0.92%; RR 1.1; 95% CI [0.8; 1.53]; P = 0.54), SSI (0.07% VS. 0.07%; RR 0.99; 95% CI [0.34; 2.9]; P = 0.98), hematoma (3.6% vs. 1.2%; RR 3.18; 95% CI [0.84; 12.1]; P = 0.09), and conversion rates (1.1% vs. 0.9%; RR 1.26; 95% CI [0.91; 1.72]; P = 0.16). However, subgroup analysis of TEP technique in patients with previous prostatectomy showed higher conversion rates (2.4% vs. 0%; RR 20; 95% CI [2.9; 138.2]; P < 0.01). Analysis using funnel plots showed the absence of publication bias in the study outcomes.

CONCLUSION

This comprehensive analysis indicates that patients with a history of prostatectomy undergoing MIS IHR may present higher postoperative complications and an increased operative time. Further comparative studies are needed to evaluate the cumulative impact of MIS IHR in patients with previous prostatectomy.

Inguinal hernia repair in patients with artificial urinary sphincter after radical prostatectomy

PURPOSE

Stress urinary incontinence (UI) often develops after radical prostatectomy for prostate cancer, and in those patients with moderate-to-severe stress UI an artificial urinary sphincter (AUS) is implanted. Inguinal hernias (IHs) often occur after radical prostatectomy. As the prevalence of AUS implantation increases, it is possible to encounter patients with IHs undergoing AUS implantation (IHA). This study investigated our treatment and discussed an appropriate approach for IHAs.

METHODS

We retrospectively investigated patients who underwent IH repair with AUS implantation at our hospital from January 2018 to March 2023. We classified IHAs into Types A-D based on the positions of the IHs and AUS devices (the positions of the control pump, pressure-regulating balloon, and connecting tube). The hernia and control pump were ipsilateral in Types A and B, whereas the hernia and pressure-regulating balloon were ipsilateral in Types A and C.

RESULTS

This study included 12 IHs of 11 patients. The median patient age was 77 years. We conducted open repair in nine patients with all types and laparoscopic repair in two patients with Type B. The median operation times for unilateral and bilateral repairs were 96 and 182 min, respectively. There were no complications with AUS or hernia surgeries.

CONCLUSION

IHA has its own characteristics, and multidisciplinary knowledge thereof will help surgeons safely perform IH surgery.

Risk of conversion after intended total extraperitoneal hernia repair for inguinal hernia depends on type of previous abdominal surgery

PURPOSE

Risk of total extraperitoneal hernia repair (TEP) in patients with previous lower abdominal surgery (PLAS) is still debated. The present study was designed to assess the rate of conversion in TEP for inguinal hernia stratified by type of PLAS.

METHODS

Variables on patients undergoing TEP inguinal hernia repair at our center were prospectively collected between July 2012 and May 2018. Patients with PLAS were compared to patients without PLAS. Furthermore, the most frequent subtypes of PLAS were defined and TEP conversion rate was stratified according to type of PLAS.

RESULTS

A total of 1589 patients with TEP inguinal hernia repair were identified including 152 (9.6%) patients with PLAS. Operative time was increased in patients with PLAS (70 vs. 60 min, p < 0.001). Conversion from TEP to transabdominal preperitoneal patch plasty (TAPP) or Lichtenstein open inguinal hernia repair was eight-times more frequent after PLAS (8% vs. 1%, p < 0.001). Considering type of PLAS, open appendectomy was most frequently encountered, followed by multiple PLAS and surgery to the bladder and prostate (53%, 11% and 10%). After stratification for type of PLAS, conversions were most frequently found after previous surgery to the bladder or prostate and after multiple PLAS (conversion rate of 20% and 24%, p < 0.001). In contrast, conversion rate after open appendectomy was not increased.

CONCLUSION

PLAS to the bladder and prostate is associated with TEP conversion. Selected patients might profit from a different operative approach for inguinal hernia repair.

Long term efficacy of prosthetic inguinal herniorrhaphy concomitant with robot-assisted laparoscopic radical prostatectomy

PURPOSE

Patients who undergo robot-assisted laparoscopic radical prostatectomy (RARP) may present concurrent or secondary inguinal hernia (IH). Surgical repair of IH simultaneously with RARP has been reported. We aimed to assess the long-term efficacy of concurrent prosthetic IH repair with RARP.

METHODS

Data for consecutive patients undergoing concurrent IH repair with RARP for localized prostate cancer at our institution between 2006 and 2017 were retrospectively analysed. Patients were matched based on age, BMI, and year of surgery, with patients undergoing RARP alone. IH repair was performed with a polyester mesh. Efficacy of IH repair was the primary outcome. Patient characteristics, perioperative data, recurrence and treatment were recorded.

RESULTS

A total of 136 men were included, 50% treated by RARP and concurrent IH, 50% by RARP alone. Mean age was 65 years (SD 6) and mean BMI 26.8 (SD 2.5). IH was diagnosed preoperatively in 42 patients (62%) or intraoperatively in 26 patients (38%). A total 18 patients (26%) had bilateral hernias and 50 patients had unilateral hernias (right 31%, left 43%). There was no significant difference between the two groups regarding perioperative data. The herniorrhaphy added 34 min to the operative time (p < 0.001). After a mean follow-up of 106 months [SD 38], 9 patients (13%) presented recurrence of IH, with a mean time to recurrence of 43 months [SD 35]. Age was significantly associated with IH recurrence (p = 0.0007).

CONCLUSION

Concomitant IH repair and RARP appear to be a safe procedure with good long-term safety and efficacy, without significantly increasing morbidity.

Early outcomes of robotic transabdominal preperitoneal inguinal hernia repair: a retrospective single-institution study in Korea

Purpose

Robotic hernia repair has increased in popularity since the introduction of da Vinci robots (Intuitive Surgical). However, we lack quantitative analyses of its potential benefits. Herein, we report our initial experience with robotic transabdominal preperitoneal (R-TAPP) inguinal hernia repair.

Methods

We retrospectively reviewed the data from patients who underwent R-TAPP inguinal hernia repair with a prosthetic mesh using the da Vinci platform. Data on patient characteristics and surgical outcomes were also collected.

Results

Twenty-one patients (including 20 male patients [95.2%]) with a mean age of 54.1 ±16.4 years and body mass index of 23.8 ± 1.9 kg/m2 underwent R-TAPP inguinal hernia repair. Bilateral hernia repair was performed in two patients (9.5%), and six patients (28.5%) with scrotal hernia underwent R-TAPP hernia repair. A sigmoid colon sliding hernia was present in three patients (14.3%). The mean operation and console times were 91.8 ± 20.4 minutes and 154.5 ± 26.2 minutes, and 61.4 ± 16.9 minutes and 128.0 ± 25.5 minutes for unilateral and bilateral inguinal hernia, respectively. Spermatic vessel injury was identified intraoperatively in one patient. Two minor postoperative complications, postoperative ileus, and wound seroma were reported. The mean duration of hospitalization was 3.8 ± 0.9 days. No recurrence or conversion to open surgery was required.

Conclusion

Our findings suggest that R-TAPP inguinal hernia repair is safe and feasible. Its cost-effectiveness, optimal procedural steps, and indications for a robotic approach require further investigation.
