Parastomal Hernia Repair With 3-D Mesh Implants After Radical Cystectomy and Ileal Conduit Urinary Diversion - A Single-center Experience Using a Purpose Made Alloplastic Mesh Implant

Repair of parastomal hernia after Bricker procedure: retrospective consecutive experience of a tertiary center

BACKGROUND

Ileal conduit parastomal hernias (ICPHs) are frequent after radical cystectomy with ileal conduit urinary diversion, but their management is debated. This study aimed to review the results of ICPH repair according to Sugarbaker or Sandwich techniques, with special interest in ICPH recurrence and urological complications.

METHODS

The authors reviewed a consecutive series of patients undergoing ICPH repair between January 2014 and December 2020. Primary endpoints were ICPH recurrences at clinical exam and cross-sectional abdominal computed tomography (CT) scans. Secondary endpoints were any other complications possibly related to the ICPH repair.

RESULTS

Twenty-three patients underwent ICPH repair surgery (16 Sugarbaker and 7 Sandwich techniques) during the study period. Sixteen patients underwent a primary laparoscopic approach. All but one patient underwent at least one abdominal CT during the follow-up. Median clinical and CT scan follow-up times were 57 and 50.5 months, respectively. Clinical and CT ICPH recurrence rates were 4.5% and 13% at 5 years, respectively. Eighteen patients (78%) suffered no urological complications during the follow-up period, but three patients (13%) needed redo surgery on the urinary ileal conduit.

CONCLUSION

The modified Sugarbaker or Sandwich techniques might be considered as promising techniques for ICPH repair with a low rate of recurrence. The urological complications, and particularly the ileal conduit-related issues, need to be evaluated in further studies. Controlled and prospective data are required to compare the Sugarbaker and Sandwich techniques to the Keyhole approach for ICPH repairs.

Surgical strategies for recurrent parastomal hernia after a primary repair with a Dynamesh® IPST mesh

PURPOSE

To introduce our surgical strategies for recurrent parastomal hernia after a primary repair with a Dynamesh^® IPST mesh.

METHODS

Ten patients who underwent recurrent parastomal hernia repair with previous Dynamesh^® IPST mesh use were analyzed retrospectively. Distinct surgery strategies were applied. Accordingly, we investigated the recurrence rate and postoperative complications in these patients, who were followed for an average of 35.9 months after surgery.

RESULTS

There was no recorded death and no readmission during the 30-day postoperative period. And the lap-re-do Sugarbaker group had no recurrence, whereas the open suture group had one recurrence (16.7%). One patient in the Sugarbaker group developed ileus and recovered conservatively during the follow-up period. There were no other complications, including seroma, mesh infection and bulging, or prolonged postoperative pain.

CONCLUSIONS

We offer two predominant surgery strategies for recurrent parastomal hernia with a previous Dynamesh^® IPST mesh usage, the open suture repair, and the Lap-re-do Sugarbaker repair. Even though the results of the Lap-re-do Sugarbaker repair are satisfactory, we recommend the open suture technique as it is safer in a setting of dense adhesions in recurrent parastomal hernias.

Parastomal hernias after cystectomy and ileal conduit urinary diversion: surgical treatment and the use of prophylactic mesh: a systematic review

Background

Parastomal hernia after ileal conduit urinary diversion is an underestimated and undertreated clinical entity, which heavily impairs patients’ quality of life due to symptoms of pain, leakage, application or skin problems. As for all gastrointestinal stomata the best surgical repair technique has yet to be determined. Thereby, surgery for ileal conduit parastomal hernias poses some specific perioperative challenges. This review aims to give an overview of current evidence on the surgical treatment of parastomal hernia after cystectomy and ileal conduit urinary diversion, and on the use of prophylactic mesh at index surgery in its prevention.

Methods

A systematic review was performed according to PRISMA-guidelines. The electronic databases Embase, PubMed, Cochrane Library, and Web of Science were searched. Studies were included if they presented postoperative outcomes of patients undergoing surgical treatment of parastomal hernia at the ileal conduit site, irrespective of the technique used. A search was performed to identify additional studies on prophylactic mesh in the prevention of ileal conduit parastomal hernia, that were not identified by the initial search.

Results

Eight retrospective case-series were included for analysis, reporting different surgical techniques. If reported, highest complication rate was 45%. Recurrence rates varied highly, ranging from 0 to 80%. Notably, lower recurrence rates were reported in studies with shorter follow-up. Overall, available data suggest significant morbidity after the surgical treatment of ileal conduit parastomal hernias. Data from five conference abstracts on the matter were retrieved, and systematically reported. Regarding prophylactic mesh in the prevention of ileal conduit parastomal hernia, 5 communications were identified. All of them used keyhole mesh in a retromuscular position, and reported on favorable results in the mesh group without an increase in mesh-related complications.

Conclusion

Data on the surgical treatment of ileal conduit parastomal hernias and the use of prophylactic mesh in its prevention is scarce. Given the specific perioperative challenges and the paucity of reported results, more high-quality evidence is needed to determine the optimal treatment of this specific surgical problem. Initial results on the use of prophylactic mesh in the prevention of ileal conduit parastomal hernias seem promising.

A keyhole approach gives a sound repair for ileal conduit parastomal hernia

PURPOSE

The purpose of this study was to report and evaluate a laparoscopic surgical technique for the treatment of parastomal hernia (PSH) after ileal conduit urinary diversion aiming to minimize PSH recurrence and perioperative complications.

METHODS

We retrospectively evaluated all patients who underwent a PSH (after ileal conduit urinary diversion) repair at Addenbrookes Hospital, Cambridge. As a surgical approach, a laparoscopic repair with mesh was utilized in all cases. Subsequently, we performed a voluntary follow-up of the patients to evaluate long-term recurrence and complication rates. In addition, we conducted a reassessment of the cross-sectional imaging available.

RESULTS

Between November 2008 and December 2019, 27 patients underwent hernia repair due to a clinically significant hernia. Out of those patients, one suffered from a post-operative wound infection. In total 23 patients participated in the follow-up with a median follow-up period of 91 months. Follow-up examination revealed two cases of recurrent PSH (8.7% of patients followed up), four patients suffered from minor complications (14.8%).

CONCLUSION

Repair of PSH associated with ileal conduit is particularly scarce. Our surgical approach presents the only laparoscopic case series of an effective method for treating a PSH from an ileal conduit with a low complication and recurrence rate.

How-I-do-it: minimally invasive repair of ileal conduit parastomal hernias

BACKGROUND

Parastomal hernia after radical cystectomy and ileal conduit urinary diversion is an underestimated and undertreated condition with significant impact on quality of life. However, its surgical treatment is challenging and prone to complications and the optimal surgical treatment of this condition remains to be determined.

METHODS

In this article, we describe our surgical techniques in the minimally invasive treatment of ileal conduit parastomal hernia and present our preliminary results. In a retrospective single-center design, a prospectively maintained database was screened. Data from all patients undergoing surgical treatment for a parastomal hernia after cystectomy and ileal conduit urinary diversion in our center were collected.

RESULTS

Between May 2016 and June 2020, 15 patients underwent minimally invasive repair of a parastomal hernia of an ileal conduit. Details on the surgical approach are provided, along with a flow chart to standardize the choice of surgical technique, depending on the presence of a concomitant midline incisional hernia and perioperative findings. The majority of patients were treated with robotic-assisted laparoscopic surgery (10/15; 66.7%). Median postoperative hospital stay was 5 days. One-third of patients developed a postoperative urinary infection. Median follow-up was 366 days. One patient developed a local recurrence of her parastomal hernia on day 66 postoperatively, treated with intraperitoneal mesh.

CONCLUSION

The minimally invasive surgical treatment of a parastomal hernia after ileal conduit urinary diversion poses specific perioperative challenges that require a broad surgical armamentarium and a tailored approach. Preliminary results confirm a significant morbidity after this type of surgery.

Parastomal hernia after radical cystectomy with ileal conduit diversion: a narrative review

Radical cystectomy (RC) with ileal conduit urinary diversion has become a common surgical procedure. Stomal complications and particularly parastomal hernia (PH) are the most frequent complications and causes of reintervention after RC with ileal conduit urinary diversion. PH is usually asymptomatic. When PH increases in size and becomes symptomatic, it clearly impairs patients' quality of life in terms of physical limitation, mental distress and social interaction. The aim of this article was to review the current knowledge on PH after RC with ileal conduit urinary diversion, regarding its natural history, risk factors, prevention and surgical management. There is no strong recommendation on the ideal surgical technique for repair of PH after RC, but laparoscopic Sugarbaker or Sandwich techniques with non-absorbable meshes are emerging as the preferred modern means of PH repair. Techniques for prevention and repair of PH after RC need to be specifically evaluated in future prospective studies.

Illeal conduit associated parastomal hernias: A novel laparoscopic top hat repair

Parastomal hernias (PH) are a well-known complication following ileal conduit urinary diversion. We present a case report of a woman in her mid-nineties with a symptomatic parastomal hernia at the site of her ileal conduit which was repaired laparoscopically by an inverted top-hat technique. The "top hat" is constructed by assembling a transected ring of synthetic mesh with a secondary mesh cylinder and laparoscopically securing this mesh construct in an underlay fashion. At eighteen months follow-up, the patient remains pain free and without evidence of hernia recurrence.

Incidence and risk factors of parastomal hernia after radical cystectomy and ileal conduit diversion: a systematic review and meta-analysis

Background

Our aim is to report the incidence and risk factors of parastomal hernia (PH) after radical cystectomy (RC) and ileal conduit (IC) diversion with a cumulative analysis.

Methods

Various databases, including PubMed, the Cochrane Library, Embase and Web of Science, were retrieved electronically and manually to identify eligible studies from inception to August 20, 2020. Two reviewers independently searched the above databases and selected the studies using prespecified standardized criteria. The Newcastle-Ottawa Scale (NOS) was used to assess the risk of bias in the included studies, and the data was completed by STATA version 14.2.

Results

Fifteen studies were included in the final analysis. A pooled analysis of eight studies representing 1,878 patients reported the incidence of overall radiographic PH was 23% (95% CI: 17–29%). The 1-year PH incidence rate and 2-year incidence rate of RC and IC were 14% (95% CI: 6–22%) and 26% (95% CI: 14–38%), respectively. A pooled analysis of nine studies reported the incidence of clinically evident PH was 15% (95% CI: 10–19%). PH-related symptoms were reported in six studies, and the pooled result was 29% (95% CI: 24–33%), and a pooled analysis of ten studies showed that 20% (95% CI: 11–28%) of patients required surgical repair. However, it’s noteworthy that among symptomatic PH patients undergoing surgical repair, the pooled analysis of five studies showed that up to 26% (95% CI: 16–36%) of patients suffered PH recurrence. The most frequent risk factor was body mass index (BMI). Patients with BMI ≥22.9 kg/m² experienced 2.92-fold higher risk of PH than their counterparts [hazard ratio (HR): 2.92; 95% CI: 1.65–5.19].

Conclusions

Our findings indicated that the PH incidence rate after RC and IC was significantly higher in radiographic evaluation than that of clinical examination, and the recurrence of repairment is considerable for patients requiring reconstruction.

[Bladder cancer - complications related to urinary diversion]

Even today, radical cystectomy with urinary diversion is one of the most complicated procedures in uro-oncology. Particularly in the long-term course, but also perioperatively, problems caused by urinary diversion play a significant role.Perioperatively, gastrointestinal problems such as an ileus, but also infections and early complications of the different anastomoses are most important. While ileus and perioperative infections can usually be treated conservatively, failure of the intestinal or ureteroileal anastomoses require regular surgical revisions.In the long-term follow-up, scarring can lead to chronic obstruction of urinary flow and, in the case of continental urinary diversions, to stone formation. These complications, as well as parastomal hernias in patients with poor conduits, may require further therapy. Functional bowel disorders may impair patients' quality of life significantly.Improved preoperative preparation and accompanying measures during the inpatient stay can significantly reduce non-surgical complications.Cystectomy with therapy-associated morbidity is a classical example of when surgery must be performed at specialised centers to reduce complications perioperatively as well as in follow-up.
