Total extraperitoneal (TEP) management of mesh erosion into bladder following transabdominal preperitoneal inguinal hernia repair (TAPP)

Robotic partial cystectomy with excision of mesh after inguinal hernia repair: a case report

BACKGROUND

Mesh erosion into the bladder after hernioplasty is sparsely reported in literature and may be underestimated in clinical practice. We report a case of a patient who was referred to our department due to recurrent urinary tract infections caused by a bladder stone due to mesh migration after inguinal hernia repair 22 years ago.

CASE PRESENTATION

A 67-year-old male patient was referred from the outpatient urologist for transurethral resection of the prostate in September 2021 due to recurrent urinary tract infections caused by benign prostatic enlargement and bladder stone formation. During the operation, parts of the stone were smashed and the prostate was resected. Additionally, a mesh eroding from the bladder roof was detected masqueraded by the stone. A computed tomography scan, which was performed afterwards, revealed a 20 × 25 mm mesh migration into the bladder after inguinal hernia repair on the left with concomitant stone adhesion to the mesh. After revealing patient history, an inguinal hernia repair with mesh implantation was done 22 years ago. A robotic assisted partial cystectomy and mesh excision was performed. The patient recovered well.

CONCLUSION

Mesh erosion into the urinary bladder after hernia repair can occur up to two decades after the primary operation. Although it is rarely reported, it can be a possible cause for recurrent urinary tract infections and therefore a mentionable complication after inguinal hernia operation. Robotic-assisted laparoscopic partial cystectomy with complete excision of the mesh is an option for definitive treatment.

Intestinal erosion caused by meshoma displacement: A case report

BACKGROUND

A meshoma formation and erosion to the small intestine is rare. Herein, we report one case of a meshoma that was not treated early; causing it to displace and erode the small intestine, with infection, complete control of symptoms was achieved after removal of the infected patch mass, no recurrence of hernia after 2 years of follow-up.

CASE SUMMARY

A 62-year-old male patient presented with recurrent abdominal pain repeatedly for 1 wk, which has worsened 2 d before admition, accompanied by fever. Five years before presentation he underwent right inguinal hernia Plug and patch repair approach. Two years ago, a computed tomography scan revealed a right lower abdominal mass with soft tissue density, measuring approximately 30 mm × 17 mm, which was diagnosed as meshoma that was not treated. The patient had poorly controlled diabetes in the past year.

CONCLUSION

The formation of meshoma is rare, and that if not treated in time it might erode and require resection of the involved organ.

Treatment of mesh infection after inguinal hernia repair: 3-year experience with 120 patients

PURPOSE

Mesh infection is a devastating complication of sterile hernia repair surgery. This study was performed to assess the short- and long-term outcomes following treatment for mesh infection after inguinal hernia repair.

METHODS

This single-center retrospective study included all patients who developed mesh infection after inguinal hernia repair from January 2018 to December 2020. Patient demographics, mesh infection characteristics, microbiology, features of surgery, short- and long-term outcomes, and follow-up data were analyzed.

RESULTS

In total, 120 patients (8 women, 112 men; mean age, 54.4 years; mean body mass index, 24.8 kg/m²) were treated for mesh infection. The cultures were positive in 88 patients; 62.5% of these were positive for Staphylococcus aureus. Laparoscopic exploration was performed in 108 patients. Seventy patients underwent complete removal of infected mesh, and 50 underwent partial removal. During the short-term follow-up, 11 patients developed a minor wound infection and were treated with dressings and antibiotics, 1 developed a wound infection requiring debridement, 30 developed seromas, and 3 developed hematomas that did not require surgical intervention. During the mean follow-up of 39.1 months, 4 patients developed hernia recurrence, 2 experienced chronic pain, and 23 developed recurrent infection requiring reoperation in the partial mesh removal group (in contrast, only 4 patients in the complete mesh removal group developed recurrent infection, with a statistically significant difference).

CONCLUSION

The outcome of mesh infection after inguinal hernia repair treated by mesh removal is satisfactory. Systematic individualized treatment by experienced experts based on the patient's previous repair technique, implanted mesh, and physical condition is recommended.

Laparoscopic management of mesh migration into urinary bladder following laparoscopic totally extraperitoneal inguinal hernia repair-A case report

•

Mesh migration into bladder should be considered a differential in case of patients with recurrent UTI and history of laparoscopic hernioplasty.

•

Computed tomography and cystoscopy will aid in the diagnosis of such cases and removal by TAPP approach is better than other approaches.

•

This case report will help the readers to get a knowledge on such an approach as it is easily reproducible.

•

Care should be taken to remove all the mesh as remnant mesh particles may act as a nidus for infection.

Introduction and importance

Mesh migration into urinary bladder is one of the rare complications following inguinal hernia repair (Laparoscopic/Open). On reviewing the literature, erosion of mesh following inguinal hernia repair has been into the urinary bladder in most of the cases, and the erosion may occur as early or late complication. It may occur as a result of improper suturing, inadequate fixation or foreign body reaction. The most common presentation is recurrent urinary tract infection and haematuria and may mimic bladder malignancy.

Case presentation

A 38-year male presented with recurrent UTI and mimicked to have bladder malignancy on CT scan. On Cystoscopy, mesh along with tackers is visualized within the bladder lumen. A diagnosis of Mesh migration into bladder following laparoscopic inguinal hernia repair was made. The Patient underwent Complete laparoscopic removal of mesh with partial cystectomy, per urethral and suprapubic catheter were placed. The patient made a good recovery without any post-operative complications. On follow-up, Patient underwent Fluoroscopy to look for urinary leakage, and suprapubic catheter removal was done. Patient is asymptomatic on follow-up.

Clinical discussion

Mesh migration into bladder is one the rare complications following laparoscopic hernia repair. Proper preoperative evaluation is necessary to determine whether mesh is free floating in the bladder lumen or adherent to bladder wall. This will help in deciding the surgical technique for route of extraction.

Conclusion

A case of mesh migration into the bladder can be easily managed by laparoscopic TAPP approach and it is better approach compared to other techniques.

Laparoscopic evaluation and management of 47 patients with late-onset mesh infection after inguinal hernioplasty

INTRODUCTION

Mesh infection after inguinal hernioplasty can be complicated especially when it is caused by chronic fistula. Explantation of the infected mesh is inevitable when conservative treatment fails and is considered to be the key step toward development of future therapies. Our purpose was to determine the results of laparoscopic exploration and summarize the treatment experience of the late-onset mesh infection.

METHODS

We analyzed 47 patients with late-onset mesh infection treated at our hernia center. The medical records of these patients were retrospectively reviewed, and information regarding presentation, approach of previous hernia repair, type of mesh, operative findings, bacteriological examination result, and postoperative complications were obtained. All of the patients underwent laparoscopic exploration to identify the abscess and fistula, further debridement and treatment was performed afterwards according to the exploration results.

RESULTS

All the operative courses were uneventful. Laparoscopy revealed four intestinal fistula and one bladder fistula. Four cases of all underwent debridement and drainage using laparoscopic approach only, and the others were converted to open surgery after laparoscopic exploration to remove the infected mesh. There were two hernia recurrence and nine wound infection during the follow-up period; all the patients had an eventually recovery.

CONCLUSIONS

Laparoscopic exploration is an effective and minimally invasive method for managing the late-onset infection which can identify whether internal organ was involved and consult for the further treatment. The approach of mesh removal should be tailored according to the exploration results.

Mesh erosion into urinary bladder, rare condition but important to know

BACKGROUND

Although rare, mesh migration or erosion into viscera has been reported as case report, and most of the cases involved with the urinary bladder. With the increasing use of prosthetic mesh in hernia repair, this severe complication would increase in the future; thus, we feel that it is necessary to analyze the clinical patterns of mesh erosion into the urinary bladder, and to discuss the prevention and treatment of this severe complication.

METHOD

In the present study, we made a thorough identification of all published reports on mesh migration or erosion into the urinary bladder, and the data were summarized, analysed, and discussed.

RESULTS

A total of 23 cases of mesh erosion into urinary bladder were reported since 1994. Among them, two cases were from incisional hernia repairs, and 21 cases were following inguinal hernia repairs. The most frequently reported procedures were TAPP, followed by TEP. The duration from initial hernia repair to the onset of mesh erosion into bladder varied greatly (3 months-20 years), and most of cases occurred in 1-5 years after the initial hernia repair (10/23, 43.5%), while a certain number of cases occurred 10 years after hernia repair (6/23, 26.1%). Most of these cases were treated with mesh removal via a open procedure (12/22, 54.5%), and in 7 cases (7/22, 31.8%), the partial cystectomy was performed as well as mesh removal. Laparoscopic or robotic treatment procedures were performed in three cases.

CONCLUSION

Mesh erosion into the urinary bladder can occur after both open and laparoscopic inguinal hernia repairs in a wide range of duration. This complication most frequently happened following laparoscopic inguinal hernia repair. It was usually treated with partial or complete mesh removal, with or without partial cystectomy. A registry system is necessary for monitoring this complication.
