Recurrent Thigh Abscess with Necrotizing Fasciitis from a Retained Transobturator Sling Segment

Necrotizing Fasciitis Complicating Transobturator Tape Operation

Midurethral slings (MUSs) have been used successfully for the last 20 years in the treatment of stress urinary incontinence and accepted as the gold standard surgical procedure. High success rates and minimal invasiveness of surgery are among the most important advantages, but sometimes serious complications can occur during or after surgery. Although serious complications are rare after widely performed transobturator tape (TOT) operation, awareness, early diagnosis, and aggressive management are essential as they can progress with serious morbidity and mortality. In order to reduce the infectious complications after MUS procedures, in addition to sterility of the operating theater and the operating equipment, the type of mesh used and the preparation of the surgical site are crucial. We aimed to pre-sent the successful management of a case of necrotizing fasciitis in a TOT patient.

3-year results of transvaginal cystocele repair with transobturator four-arm mesh: A prospective study of 105 patients

OBJECTIVES

To evaluate the long-term efficacy and safety of transobturator four-arm mesh for treating cystoceles.

PATIENTS AND METHODS

In this prospective study, 105 patients had a cystocele corrected between January 2004 and December 2008. All patients had a symptomatic cystocele of stage ⩾2 according to the Baden-Walker halfway stratification. We used only the transobturator four-arm mesh kit (Surgimesh®, Aspide Medical, France). All surgical procedures were carried out by the same experienced surgeon. The patients' characteristics and surgical variables were recorded prospectively. The anatomical outcome, as measured by a physical examination and postoperative stratification of prolapse, and functional outcome, as assessed by a questionnaire derived from the French equivalents of the Pelvic Floor Distress Inventory, Pelvic Floor Impact Questionnaire and the Pelvic Organ Prolapse-Urinary Incontinence-Sexual Questionnaire, were considered as the primary outcome measures. Peri- and postoperative complications constituted the secondary outcome measures.

RESULTS

At 36 months after surgery the anatomical success rate (stage 0 or 1) was 93%. On a functional level, all the scores of quality of life and sexuality were improved. The overall satisfaction score (visual analogue scale) was 71.4%. There were no perioperative adverse events. Mesh erosion was reported in 7.6% and mesh retraction in 5.7% of the patients.

CONCLUSIONS

If the guidelines and precautions are followed, vaginal prosthetic surgery for genitourinary prolapse has shown long-term benefits. It provides excellent results both anatomically and functionally. However, complications are not negligible and some are specific to prosthetic surgery.

Complications of synthetic slings used in female stress urinary incontinence and applicability of the new IUGA-ICS classification

OBJECTIVES

To analyze different complications of synthetic suburethral slings, and to apply the new "IUGA-ICS classification of complications directly related to the insertion of prosthesis (meshes, implants, tapes) and grafts in female pelvic floor surgery" to the list of complications, check its applicability, and give suggestions regarding possible improvements.

STUDY DESIGN

This study is an analysis of complications of synthetic suburethral slings. Data on type of complication, time interval between the insertion of the prosthesis and the onset of symptoms of complication, type and nature of prosthesis, and management process were documented. Additional descriptions of the sling position in relation to lower urinary tract, shrinkage or prominence of the prosthesis, and intra-operative nature of the prosthetic material were collected for analysis.

RESULTS

From the year 2003 to 2010, 376 women with complications of synthetic suburethral slings were managed surgically and the data were analyzed. Overactive bladder (OAB) at 54%, lower urinary tract obstruction (48%), vaginal exposure (19%), and pain (14%) were the most frequent complications. Infection, fistulae, urinary tract penetration, and groin/thigh pain were other complications. The new IUGA-ICS classification could be applied to most of the types of complications, a notable exception being de novo development of overactive bladder. Also category 4B of IUGA-ICS classifications encompasses a wide clinical variety of complications and may need reconsideration.

CONCLUSION

De novo OAB seems to be the commonest complication of synthetic suburethral slings, followed by obstruction, vaginal exposure, and long term pain. The new IUGA-ICS classification on complications has good general applicability; some minor changes may be useful in the future.

Groin abscess due to a forgotten midurethral sling connector

Midurethral slings (MUS) have been used for female stress urinary incontinence throughout the past decade on a worldwide scale. Although this minimally invasive treatment has high success rates, formation of groin abscesses, as well as vaginal and urethral erosions, can occur after the procedure. We report a patient presenting with groin abscess and sinus tract formation after a transobturator tape procedure. The patient exhibited a swollen sinus tract, which drained the abscess at the site of the tape entry to the obturator foramen within her inner left groin. She was referred to our department after unsuccessful medical and surgical treatments. Surgical exploration revealed a forgotten MUS connector located between the mesh and hook within the skin incision. To the best of our knowledge, this is the first report of such a case.

Necrotizing fasciitis following transobturator tape procedure: a case report and literature review

A 51-year-old diabetic woman was referred to our unit with a history of increasing pain in her right thigh and gait disturbance, 10 days following surgery for treatment of stress urinary incontinence with a transobturator tape. Examination elicited a tender right thigh associated with swelling and erythema. Inspection of the vagina revealed an exposed mesh through the vaginal erosion. Plain radiographs and magnetic resonance imaging revealed large thigh abscesses suggestive of gas gangrene from the pelvis to the calf. The mesh was completely removed; extensile incisions, as well as aggressive debridement of all necrotic tissue in the thigh and calf, were performed. A diagnosis of necrotizing fasciitis with gas extending to the lower leg level was confirmed. After mesh removal, abscess drainage and debridement, the patient recovered with antibiotics and daily wound care. Three months after the operation, the patient showed no recurrence of the infection.

Acute and serious myositis with abscess in thigh muscle after transobturator tape implantation

The complications of transobturator tape (TOT) were known as lower urinary tract injury, postoperative urinary retention, urge incontinence, vaginal erosion, and etc. A 63-year-old woman presented with new onset of severe pain, heating, and swelling of the left thigh and perineum. She had undergone TOT implantation for stress urinary incontinence (SUI) 4 days previously in an outside clinic. Painful left thigh swelling and skin erythema were noted on the physical examination. A computed tomography (CT) scan showed multiple, large left medial thigh and obturator abscesses. Removal of the implanted tape and abscess drainage were performed immediately and two additional operations were needed for proper abscess drainage. We believe this case to be one of the most serious complications to occur since the introduction of the TOT procedure. Here we report this case and discuss its initial management along with a review of the literature.
