1/65. Use of polyglactin 910 mesh (Vicryl) in pelvic oncologic surgery.Various synthetic materials have been shown to be useful surgical adjuncts in shielding the small intestine from pelvic radiation or in creating a new pelvic floor after major radical resections. Promising preliminary results with a polyglactin 910 (Vicryl) mesh in preventing radiation enteropathy prompted the authors to evaluate its clinical usefulness in reconstruction of the pelvic floor. Use of this mesh in pelvic exenterations (five total, one posterior) for advanced or recurrent gynecologic malignancies was associated with one enteroperineal fistula but no pelvic infection. In comparison with other pelvic reconstruction devices, this absorbable mesh significantly reduced intestinal morbidities in pelvic exenterations. This procedure appears to be feasible, reproducible, and safe, especially in patients who have undergone previous irradiation or those with an unsuitable omentum.- - - - - - - - - - ranking = 1keywords = fistula (Clic here for more details about this article) |
2/65. Surgical management of acquired laryngopharyngeal fistulae.Pathological communication between the food and air passages in the neck region due to malignant disease is known. However, such a pathology arising as a result of a non malignant process is relatively uncommon, and only a handful of reports exists in the literature. The authors describe and discuss the management of two patients with laryngopharyngeal fistula of nonmalignant etiology.- - - - - - - - - - ranking = 5keywords = fistula (Clic here for more details about this article) |
3/65. Aortoesophageal fistula-relief of massive hematemesis with an endovascular stent-graft.A 59-year-old man with an esophageal carcinoma developed massive hematemesis due to aortoesophageal fistula after irradiation therapy reached 58 Gy. Emergent treatment with an endovascular stent-graft was successfully performed and the patient followed an uneventful course until he died of pneumonia 4.5 months later, which was caused by a tracheoesophageal fistula. Stent-graft repair is a safe and effective method to treat aortoesophageal fistula and may be an alternative to surgical resection.- - - - - - - - - - ranking = 7keywords = fistula (Clic here for more details about this article) |
4/65. Treatment of hostile midline back wounds: an extreme approach.The basic principles of successful wound closure remain the same: careful preoperative evaluation, removal of underlying nonviable tissue, and well-vascularized soft-tissue coverage. Many complex or "hostile" back wound closures also require stabilization of the spine and a two-layered wound closure. The use of long arteriovenous fistulas with free tissue transfer provides an additional weapon for the treatment of these complex wounds.- - - - - - - - - - ranking = 1keywords = fistula (Clic here for more details about this article) |
5/65. Fatal hemorrhage complicating carcinoma of the esophagus. Report of four cases.Four cases of esophageal carcinoma complicated by fatal hemorrhage are reported. All four patients had recently completed radiation therapy. An aortoesophageal fistula was present in two cases; fibrinoid necrosis of the esophageal arteries was present in the other two. The esophageal tumor was localized in two cases and had disappeared in one case. In one patient it had metastasized widely. Ninety-nine other reports of esophageal cancer and fatal hemorrhage are reviewed from the literature. Aortoesophageal fistula was the cause of hemorrhage in 78 cases. Occlusion of the vasa vasorum by thrombosis, inflammation, neoplastic cells or radiation injury appears to be the cause of aortic necrosis and fistula formation. Prompt surgical approach, if possible, should be used to control hemorrhage, as the primary tumor may be localized to the esophagus only.- - - - - - - - - - ranking = 3keywords = fistula (Clic here for more details about this article) |
6/65. Patient tolerance of cervical esophageal metallic stents.PURPOSE: To demonstrate that proximal esophageal stenoses and tracheoesophageal fistulas can be adequately palliated with use of metallic stents without significant foreign-body sensation. MATERIALS AND methods: Between June 1994 and March 1999, 22 patients with lesions within 3 cm of the cricopharyngeus were treated by placement of metallic stents. The series was reviewed retrospectively. Twenty patients had surgically unresectable malignant lesions, two patients had benign disease. Ten patients had associated tracheoesophageal fistulas. In all, the upper limit of the stent was between C5 vertebral body inferior endplate and the T2 vertebral body superior endplate. The case-notes were reviewed until patient death (range, 6-198 days), or to date in the two surviving patients with benign disease. RESULTS: Immediate technical success was 93% (27 of 29). Dysphagia scores improved from a median of 3 to 2 after stent placement. Eighteen of 22 (82%) patients reported no foreign-body sensation. There have been no cases of proximal migration, periprocedural perforation, or deaths. The two patients with benign disease experienced significant complications. CONCLUSION: Lesions in proximity to the cricopharyngeus can be successfully palliated without significant foreign-body sensation in the majority of patients with use of metallic stents. The authors urge caution in placing stents in patients with benign disease.- - - - - - - - - - ranking = 2keywords = fistula (Clic here for more details about this article) |
7/65. Late radiation side-effects in three patients undergoing parotid irradiation for benign disease.We report three patients in whom standard radiation therapy was given and serious late radiation damage was seen. The first patient suffered recurrent parotiditis and a parotid fistula. He was treated initially with 20 Gy in ten fractions via a 300 kV field. Further irradiation was required 1 year later and 40 Gy was given in 2 Gy fractions by an oblique anterior and posterior wedged photon pair. Ten years later he developed localized temporal bone necrosis. The second patient, with pleomorphic salivary adenoma, developed localized temporal bone necrosis 6 years after 60 Gy had been given using standard fractionation and technique. The third patient received 55 Gy in 25 fractions for a pleomorphic salivary adenoma and after 3 years developed temporal bone necrosis. Sixteen years later the same patient developed cerebellar and brainstem necrosis. All patients developed chronic persistent infection during or shortly after the radiation therapy, which increased local tissue sensitivity to late radiation damage. As a result, severe bone, cerebellar and brainstem necrosis was observed at doses that are normally considered safe. We therefore strongly recommend that any infection in a proposed irradiated area should be treated aggressively, with surgical debridement if necessary, before radiotherapy is administered, or that infection developing during or after irradiation is treated promptly.- - - - - - - - - - ranking = 1keywords = fistula (Clic here for more details about this article) |
8/65. Surgical treatment of the radiation injured bowel.Over the last 10 years, 9 patients treated by surgical procedure for radiation injuries of the bowel were studied with the following conclusions: The damage to the small intestine caused by external irradiation leads to adhesion of the bowel, perforation and postoperative anastomotic dehiscence if the irradiated bowel is used in the anastomosis. Surgical treatment for the small intestine is resection of the damaged loop. In order to determine the extent of the resection it is important that during the operation fibrosis and obstruction of vessels in the submucosa and subserosa is examined by biopsy. On the other hand, rectal ulcer and/or rectovaginal fistula is chiefly caused by intracavitary application plus external irradiation. For these lesion Hartmann operation or colostomy is performed, and the postoperative course is uneventful.- - - - - - - - - - ranking = 1keywords = fistula (Clic here for more details about this article) |
9/65. Fatal recurrent ureteroarterial fistulas after exenteration for cervical cancer.BACKGROUND: Ureteroarterial fistula (UAF) is a rare occurrence. It can be difficult to diagnose with a high mortality. We report a case of a recurrent UAF. CASE: A 38-year-old women diagnosed with cervical cancer had undergone pelvic exenteration for severe radiation-induced necrosis with a vesicovaginal and rectovaginal fistula after primary radiation therapy. hemorrhage into the urinary tract necessitated surgical intervention and vascular repair with a femoral-femoral bypass. Although these measures were effective, the patient died 6 months later following an acute hemorrhage into her conduit. Arteriogram revealed a second UAF. CONCLUSION: When urinary tract bleeding occurs in patients previously diagnosed with a gynecologic malignancy and treated with radiation therapy and extensive surgery with urinary diversion, UAF should be considered in the differential diagnoses.- - - - - - - - - - ranking = 87.594022262268keywords = vesicovaginal, fistula (Clic here for more details about this article) |
10/65. Postirradiation vesicovaginal fistula completely resolved with conservative treatment.Postirradiation vesicovaginal fistulae (VVF) pose a great challenge for the urologist. The poorly vascularized radiated tissue surrounding the fistula impairs healing and makes operative repair technically demanding. Conservative treatment for postirradiation VVF is considered inappropriate, and to our knowledge has never previously been described. We present a case of a woman with postirradiation VVF that was resolved after transurethral coagulation and 3 weeks of catheterization.- - - - - - - - - - ranking = 1292.984251615keywords = vesicovaginal fistula, vesicovaginal, fistula (Clic here for more details about this article) |
