CASE REPORT: A case of ureterovaginal fistula associated with a neglected vaginal foreign body. The patient was complaining of a foul-smelling vaginal discharge and lower abdominal pain. On vaginal examination, a hard and large foreign body was found. Examination under anesthesia was performed, and an aerosol cap was removed from her vagina. The patient developed urinary incontinence after removal of the foreign body. Subsequent work-up demonstrated the presence of a right ureterovaginal fistula. The patient underwent an abdominal ureteroneocystostomy. At one year follow up, the patient had fully recovered.
CONCLUSION: Ureterovaginal fistula following neglected vaginal foreign body is a serious condition. Early diagnosis, treatment of infection and proper surgical management can improve the outcome and decrease complications.
METHODS: After Institutional Review Board approval (99-0793B), we retrospectively studied all patients diagnosed, treated and followed up with RVF at Chang Gung Memorial Hospital, Taiwan between January 1990 and December 2009. All female patients with International Classification of Diseases RVF were included. We reviewed demographic data, socioeconomic status, clinical presentation, comorbidities, method of treatment, duration of hospitalization and clinical outcome at 12 months postoperatively.
RESULTS: A total of 397 patients were included in the study. Fifty-six patients (14.1%) had conservative treatment and 341 patients (85.9%) underwent surgical intervention. A total of 125 patients underwent simple repair while 216 patients underwent reconstruction. Three hundred and forty-four patients (86.7%) had improved outcome at 12-month follow up. Age (P = 0.003), education level (P = 0.033), ability to pay insurance (P < 0.001), and choice of treatment (P < 0.0001) were identified as significant favorable factors. An etiological factor associated with favorable outcome was RVF from obstetric complication, while that resulting from malignancy had a less favorable outcome.
CONCLUSIONS: Age, education level and ability to pay insurance significantly affect 12-month outcome of RVF. Surgery is the preferred option, while medical treatment should be used only for small rectovaginal fistulas or for patients not suitable for surgery and anesthesia. More support and assistance should be offered to those patients with unfavorable factors, such as old age, low education level and inability to afford insurance. All RVF secondary to obstetrical injury had a 100% favorable outcome compared with those secondary to surgery or malignancy. Women with suspected RVF should receive prompt and extensive evaluation to ensure immediate effective management and prevention of further serious complications.
MATERIAL AND METHODS: A prospective analysis of adult patients enrolled in the IROA.
RESULTS: Among 649 adult patients with OA 58 (8.9%) developed EAF. Indications for OA were peritonitis (51.2%) and traumatic-injury (16.8%). The most frequently utilized temporary abdominal closure techniques were Commercial-NPWT (46.8%) and Bogotà-bag (21.9%). Mean OA days were 7.9 ± 18.22. Overall mortality rate was 29.7%, with EAF having no impact on mortality. Multivariate analysis associated cancer (p = 0.018), days of OA (p = 0.003) and time to provision-of-nutrition (p = 0.016) with EAF occurrence.
CONCLUSION: Entero-atmospheric fistulas are influenced by the duration of open abdomen treatment and by the nutritional status of the patient. Peritonitis, intestinal anastomosis, negative pressure and oral or enteral nutrition were not risk factors for EAF during OA treatment.
OBJECTIVES: To assess the effectiveness and safety of various interventions for the treatment of oro-antral communications and fistulae due to dental procedures.
SEARCH METHODS: We searched the Cochrane Oral Health Group's Trials Register (whole database, to 3 July 2015), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, 2015, Issue 6), MEDLINE via OVID (1946 to 3 July 2015), EMBASE via OVID (1980 to 3 July 2015), US National Institutes of Health Trials Registry (http://clinicaltrials.gov) (whole database, to 3 July 2015) and the World Health Organization (WHO) International Clinical Trials Registry Platform (http://www.who.int/ictrp/en/) (whole database, to 3 July 2015). We also searched the reference lists of included and excluded trials for any randomised controlled trials (RCTs).
SELECTION CRITERIA: We included RCTs evaluating any intervention for treating oro-antral communications or oro-antral fistulae due to dental procedures. We excluded quasi-RCTs and cross-over trials. We excluded studies on participants who had oro-antral communications, fistulae or both related to Caldwell-Luc procedure or surgical excision of tumours.
DATA COLLECTION AND ANALYSIS: Two review authors independently selected trials. Two review authors assessed trial risk of bias and extracted data independently. We estimated risk ratios (RR) for dichotomous data, with 95% confidence intervals (CI). We assessed the overall quality of the evidence using the GRADE approach.
MAIN RESULTS: We included only one study in this review, which compared two surgical interventions: pedicled buccal fat pad flap and buccal flap for the treatment of oro-antral communications. The study involved 20 participants. The risk of bias was unclear. The relevant outcome reported in this trial was successful (complete) closure of oro-antral communication.The quality of the evidence for the primary outcome was very low. The study did not find evidence of a difference between interventions for the successful (complete) closure of an oro-antral communication (RR 1.00, 95% Cl 0.83 to 1.20) one month after the surgery. All oro-antral communications in both groups were successfully closed so there were no adverse effects due to treatment failure.We did not find trials evaluating any other intervention for treating oro-antral communications or fistulae due to dental procedures.
AUTHORS' CONCLUSIONS: We found very low quality evidence from a single small study that compared pedicled buccal fat pad and buccal flap. The evidence was insufficient to judge whether there is a difference in the effectiveness of these interventions as all oro-antral communications in the study were successfully closed by one month after surgery. Large, well-conducted RCTs investigating different interventions for the treatment of oro-antral communications and fistulae caused by dental procedures are needed to inform clinical practice.
