Cuff meshoma post-laparoscopic sacrocolpopexy: vaginal-endoscopic mesh excision

INTRODUCTION AND HYPOTHESIS

The objective was to present endoscopic images of a meshoma and describe the complete excision of a complicated mesh after sacrocolpopexy (SCP) using a combined vaginal-endoscopic technique.

METHODS

We present a video documentation of an innovative technique. A 58-year-old woman was referred with painless, foul-smelling vaginal discharge and recurrent vaginal mesh erosions. She had undergone a laparoscopic SCP 12 years ago and her symptoms had begun 5 years ago. A pre-operative MRI scan revealed a cuff meshoma and an inflammatory sinus around the mesh extending from the cuff to the sacral promontory. Under general anesthesia, a 30° hysteroscope was inserted transvaginally into the sinus, where the retained mesh was seen in the form of a shrunken meshoma, and then the mesh arms were recognized extending cephalad into a sinus tract. Under direct endoscopic visualization, the mesh was carefully mobilized at its highest point with the use of laparoscopic grasping forceps. Then, the mesh was dissected with hysteroscopic scissors in close proximity to the bone. No peri-operative complications were recognized.

RESULTS

A combined vaginal-endoscopic approach was successfully used to remove an eroded mesh and cuff meshoma after SCP.

CONCLUSION

This procedure offers a minimally invasive, low-morbidity, and rapid-recovery approach.

Total trans-obturator tape (TOT) removal; a case series including pain and urinary continence outcomes

Introduction and hypothesis

For many years, mid-urethral mesh tape (MUT) was the gold-standard procedure for management of stress urinary incontinence (SUI). However, significant concerns were raised over its safety. We present a case series of total trans-obturator tape (TOT) removals, performed in a tertiary unit over a 3-year period. We aim to evaluate improvement of pain and change in urinary continence symptoms following mesh explantation.

Methods

This is a retrospective case series of the outcomes of total TOT removal. Primary outcome is the change in pain scores following total removal, assessed preoperatively, at discharge and follow-up. Secondary outcomes were perioperative complications, including return to theatre, re-admission rates and incidence of worsening SUI and overactive bladder symptoms (OAB) postoperatively. Statistical analyses were performed using SPSS 27.0 package (IBM, Chicago, IL) and the GraphPad Prism 9 statistical packages.

Results

Nineteen women were identified. Mean age was 52 years and mean BMI was 31. Indications for mesh removal were: chronic pain (95%), vaginal exposure (37%) and pelvic sepsis (5%). No patients had return to theatre. Median intraoperative blood loss was 200 ml (interquartile range [IQR]: 150–288). Mean length of mesh excised was 22 cm. Mean postoperative hospital stay was 2 days. At follow-up, most patients (72%) reported “improvement” of their mesh-related pain at follow-up, while 6% reported “worsening” of pain. Eighty-three per cent of patients reported worsening SUI, and 50% reported worsening OAB symptoms.

Conclusions

In the absence of sepsis, significant intraoperative complications are rare during total TOT removals. While 72% of patients reported improvement of their mesh-related pain, 6% still reported worsening pain after total mesh excision.

Improvement in dyspareunia after vaginal mesh removal measured by a validated questionnaire

INTRODUCTION AND HYPOTHESIS

The objective was to examine the effect of the surgical removal of vaginally placed prolapse and incontinence mesh on sexual function. We hypothesize that patients with painful complications of mesh will experience improvement in dyspareunia and sexual function after mesh removal.

METHODS

The eligible cohort consisted of 133 women who presented with a new onset of pain attributed to mesh-augmented incontinence or prolapse surgery and who elected to undergo mesh removal between 1 August 2012 and 1 July 2013. Sexual function symptoms were assessed before and after mesh removal surgery using the Pelvic Organ Prolapse and Urinary Incontinence Sexual Function Questionnaire short form (PISQ-12). Multivariate analysis was performed to identify predictors of improvement in dyspareunia.

RESULTS

Ninety-four patients undergoing mesh removal completed a pre-operative questionnaire, 63 of whom also completed a post-operative questionnaire. After mesh removal, there was a nearly 50% reduction in the proportion of women reporting always experiencing post-operative pain with intercourse among those experiencing pre-operative pain. There was a statistically significant quantitative improvement in pain with intercourse after mesh removal based on mean change score of PISQ-12 question 5 "How often do you experience pain with intercourse?". In multivariate analysis, only history of vaginal delivery was associated with symptom improvement.

CONCLUSION

Removal of transvaginal prolapse mesh is associated with improvement in self-reported dyspareunia based on a standardized question on a validated instrument in a small cohort of women. Although larger studies are needed to confirm the relationship between mesh-augmented surgeries and post-procedural dyspareunia, these data suggest that consideration of mesh removal is a reasonable step for patients with painful intercourse attributed to mesh-augmented prolapse and incontinence surgeries.

Immunochemical and urodynamic outcomes after polypropylene mesh explant from the pelvic wall of rats

INTRODUCTION AND HYPOTHESIS

To analyze the immunochemical and urodynamic outcomes after partial versus complete excision of transvaginal polypropylene mesh (PPM) from pelvic walls of rats.

METHODS

Forty-eight female Sprague-Dawley (SD) rats were randomly distributed into seven groups: control, mesh total removal 60 days (M-T 60D), mesh total removal 180 days (M-T 180D), mesh partial removal 60 days (M-H 60D), mesh partial removal 180 days (M-H 180D), sham 60 days (Sham 60D), and sham 180 days (Sham 180D). In the mesh groups, PPM was inserted and partially (0.3 × 0.3 cm) or completely removed 30 days later. In the Sham group, the space between the vagina and bladder was dissected without placing or removing the synthetic mesh at day 1 and day 30 later. Urodynamic studies, immunochemical analysis, and Western blot were done at days 60 and 180.

RESULTS

The M-T 60D voiding pressure was significantly decreased compared to the Sham 60D and M-H 60D. The voiding interval of M-T 60D was significantly shorter than that of M-H 60D. In the M-T 60D and M-T 180D groups, the leak point pressure was significantly less than in their corresponding sham groups. IL-1 and TNF-α were significantly more intense in M-T 60D compared to M-H 60D and Sham 60D. NGF was significantly greater in M-T 60D compared to Sham 60D. There were no significant differences in MMP-2 and CD-31s throughout the group.

CONCLUSION

Total mesh excision incites a host inflammatory response and transitory lower urinary tract dysfunction. Despite the good outcomes after total excision, the invasiveness and surgical risk associated with repeated procedures should not be underestimateded.

Laparoscopic complete sacrocolpopexy mesh removal for right-sided gluteal pain and recurrent mesh erosion

AIM OF VIDEO

The aim was to demonstrate laparoscopic complete excision of sacrocolpopexy mesh from a 65-year-old woman who had presented with delayed onset of persistent right-sided gluteal pain.

METHOD

The patient was referred to our unit, having undergone a laparoscopic sacrocolpopexy for vault prolapse 7 years earlier, with a type 1 polypropylene mesh. Four years after the primary surgery, she first noticed symptoms of spontaneous vaginal pain together with deep dyspareunia, and right-sided gluteal pain. Clinical examination revealed mesh erosion at the vaginal vault. This was managed at her local hospital, with excision of the small exposed portion of the mesh and over sewing, from a vaginal approach. She continued to be symptomatic following this procedure. When her symptoms still failed to improve 3 years later, a tertiary referral was made to our unit. At laparoscopy, minimal adhesions between the bowel and the mesh were noted and divided. After carefully dissecting the right ureter and reflecting the bladder, the entire sacrocolpopexy mesh was removed with its ProTack fasteners. The entire specimen was retrieved in one piece through the open vault and the vagina was sutured with 2.0 <monocryl laparoscopically. Surgical steps begin with laparoscopic survey of the anatomy. Adhesions need to be released carefully, after developing proper surgical planes. On follow-up in clinic 12 weeks later, there was complete resolution of her symptoms, with minimal vault descent.

CONCLUSION

This video demonstrates the steps needed to undertake complete laparoscopic sacrocolpopexy mesh excision, which should be feasible for skilled laparoscopists. This approach has advantages over the open approach, with good access and visualisation of the entire course of the mesh, and more rapid recovery for the patient.

Assessing the use of the IUGA/ICS classification system for prosthesis/graft complications in publications from 2011 to 2015

INTRODUCTION AND HYPOTHESIS

Complications of pelvic organ prolapse and urinary incontinence surgery have gained increasing attention from both lay media and medical societies. The International Urogynecological Association and International Continence Society proposed the category-time-site system to classify complications in 2011. Our objective is to assess the usage of the category-time-site system in the literature.

METHODS

We conducted a systematic review and identified records using PubMed search terms "mesh" and "prolapse or incontinence" and "complication or excision" (February 2011 to December 2015) to select publications following the introduction of category-time-site system. Relevant publications were included and reviewed for study design, initial procedure, number of patients assigned codes, number of unique codes applied, purpose of assigning codes, and duration of clinical follow-up.

RESULTS

Of 167 eligible records, 23 (14 %) used the system, 137 (82 %) used no system, and 7 (4 %) used another system. They included three study designs: randomized control trials, case reports, and case series. Given the very limited amount of data, no statistical tests were performed, but trends were noted.

CONCLUSIONS

Fourteen percent of the reports in the literature describing complications related to prosthesis/graft use in pelvic surgery utilize the category-time-site system. The system's limited and inconsistent use hinders the ability to draw conclusions useful for clinical practice. Effort should be directed toward improving appropriate usage or revising the system to increase its exposure in related publications. An improved system will better prepare pelvic surgeons for assessing future generations of prostheses/grafts.
