1/123. Five-layer repair of rectovaginal fistula using a vaginal approach. A case report. We present a case of a rectovaginal fistula which was revealed as an incidental finding at the time of posterior colporrhaphy. We describe a previously unreported 5-layer repair through a vaginal approach in preference to the more frequently reported approaches of endoanal flap or conversion to a fourth degree tear. The diagnosis and management of rectovaginal fistulas is discussed. ( info) |
2/123. Embolization--an optional treatment for intractable hemorrhage from a malignant rectovaginal fistula: report of a case. PURPOSE: patients rarely have intractable hemorrhage from rectovaginal fistulas, which usually require surgical intervention. This report presents our experience with nonsurgical treatment of a high-risk patient with uncontrolled hemorrhage originating from a malignant rectovaginal fistula. methods: A 74-year-old female developed uncontrolled hemorrhage from a malignant rectovaginal fistula. Because of her poor physical condition, an embolization with metal clips of the right and left hypogastric arteries was performed, distal to the superior gluteal artery. RESULTS: Embolization was successful in controlling the rectovaginal bleeding, allowing the patient to live 12 months. She refused adjuvant radiotherapy or chemotherapy. CONCLUSIONS: Selective angiography and embolization is a worthwhile alternative in patients with uncontrolled bleeding from a malignant rectovaginal fistula who are poor candidates for surgical intervention.

3/123. cytomegalovirus colitis in individuals without apparent cause of immunodeficiency. cytomegalovirus infection is usually reported in immunocompromised patients. In this study, apparently immunocompetent patients with cytomegaloviral colitis were reviewed. Records with a diagnosis of cytomegaloviral colitis from January 1989 to June 1996 were retrieved for analysis. Ten patients were included (median age 70 yr). The major presenting symptoms were diarrhea and hematochezia. Ulceration was the main macroscopic finding. Rectal bleeding was mostly self-limiting. Three patients developed local complications (rectovaginal fistula in two; rectal stricture in one). In the two patients with rectovaginal fistula, lymphocytes subsets and proliferative response were entirely normal. In the other patient, low B lymphocyte count and low response to mitogen were demonstrated. However, the immunoglobulins were not suppressed and rectal biopsies revealed noncaseating granulomas, suggesting activated cell-mediated immunity. In conclusion, a high index of suspicion is crucial for early diagnosis of cytomegaloviral colitis in patients with bloody diarrhea, even though obvious evidence of immunodeficiency is lacking.

4/123. Successful transvaginal repair of a rectovaginal fistula developing after double-stapled anastomosis in low anterior resection: report of four cases. The management of postoperative rectovaginal fistula (RVF) after low anterior resection for rectal cancer is difficult and the results are often unsatisfactory. Among 140 patients with rectal cancer who underwent low anterior resection with a double-stapled anastomosis at our hospital between 1986 and 1996, 4 (2.9%) developed RVF as a postoperative complication. The RVF developed gradually from 9 to 128 days after low anterior resection. We describe herein our technique of using a modified transvaginal approach for RVF repair with a diverting colostomy. In all four patients, the RVFs were completely eradicated with reestablishment of intestinal continuity and did not recur during the mean follow-up period of 29.5 months, ranging from 12 to 67 months. This report serves to demonstrate that emerging RVFs secondary to stapled anastomosis in low anterior resection for rectal cancer must be recognized, and that a modified transvaginal approach provides an effective method of repair.

| lymphogranuloma venereum (LGV) is a rare form of the sexually transmitted disease caused by chlamydia trachomatis. In the united states, there are fewer than 350 cases per year. In a review of the world's literature, there has not been a case reported in the last thirty years of a case of LGV presenting as a rectovaginal fistula. We present a case of an otherwise healthy American woman who presented with a rectovaginal fistula. Although uncommon, LGV does occur in developed countries and may have devastating tissue destruction if not recognized and treated before the tertiary stage. ( info) |
| A rectovaginal fistula after delivery is a rare complication, and its management can become difficult if infection occurs. In two such cases, we administered hyperbaric oxygenation (HBO) treatment against complicated infections, and we obtained a good outcome in each case. ( info) |
7/123. rectovaginal fistula repair utilizing a cadaveric dermal allograft. rectovaginal fistula repair is commonly performed through the vagina. When recurrent fistulae occur, healthy tissue such as a muscle or fat pad may be interposed to facilitate healing and prevent recurrence. A woman developed a postpartum rectovaginal fistula after her third-degree perineal laceration failed to heal completely. Two subsequent fistula repairs were performed, with recurrence following each procedure. The fistula was ultimately repaired by performing a layered closure and interposing a cadaveric dermal allograft between the rectovaginal septum and vaginal epithelium. Allogenic cadaveric graft may be a viable alternative to traditional autologous flaps for the repair of recurrent or complicated rectovaginal fistulae. ( info) |
8/123. Rectal duplication. Duplications of the alimentary tract are of a great rarity, particularly so in the rectum. Because of its rarity, the difficulty of making a correct diagnosis and of selection of proper approach for treatment, this entity bears a special significance. The present case report deals with a female newborn who presented with imperforate anus and a rectovestibular fistula and a mass prolapsing at the introitus. Complete excision of the mass was carried out through the perineal approach and the child then underwent, a PSARP for the correction of the rectal anomaly. histology confirmed the mass to be a rectal duplication.

9/123. H-type rectovaginal fistula associated with the Currarino triad. We describe a case of H-type rectovaginal fistula associated with the Currarino triad (anorectal stenosis, sacral defect, presacral mass). Presenting symptoms included passage of feces per vaginam, signs of intestinal subocclusion without perianal inflammation, left leg paresis and foul-smelling urine. An anterior sacral meningocele was repaired at the age of three months. At age 18 months the fistula was excised through a perineal approach after creation of a protective colostomy. Diagnostic and therapeutic aspects of this malformation are discussed. ( info) |
10/123. Recurrent rectoneovaginal fistula caused by an incidental squamous cell carcinoma of the neovagina in Mayer-Rokitansky-Kuster-Hauser syndrome. OBJECTIVE: Mayer-Rokitansky-Kuster-Hauser syndrome is a congenital malformation characterized by an absence of the vagina associated with a variable abnormality of the uterus and the urinary tract but functional ovaries. Surgical correction requires the creation of a neovaginal canal by the performance of a neovaginoplasty and an accurate long-term application of an artificial phallus phantom to avoid secondary shrinkage of the canal. Due to the chronic alteration of the posterior neovaginal wall, ulcers and consecutive fistulae may occur. We report the clinical course of a female who required surgical intervention for a rectoneovaginal fistula and developed a recurrence of the fistula due to one of the extremely rare squamous cell carcinomas of the neovaginal epithelium in order to show potential diagnostic and therapeutic features. METHOD: The systematic report of a case is presented. RESULT: Almost 13 years following the initial construction of a neovagina the patient developed a single-tract rectoneovaginal fistula. After surgical repair she represented with a recurrence due to a vast squamous cell carcinoma of the former operation site. Tumor en bloc resection was performed and currently (follow-up: 4 months) she has no signs of new tumor progression. CONCLUSION: Creation of a neovagina is the standard procedure for treating vaginal atresia or aplasia. Because of the long clinical course postoperatively, complications may occur. This report of a case of a malignant transformation in neovaginal epithelium shows the potential risk of malignancy and underlines the necessity of a close follow-up. ( info) |
