Rupture of an isolated internal iliac artery aneurysm into the rectum: Report of a case

Aneurysmal rupture into the intestinal tract is a rare but disastrous complication of an internal iliac artery aneurysm. We report herein the successful surgical repair of a fistula between a huge aneurysm of the right internal iliac artery and the rectum in an 81-year-old man. After a femoro-femoral cross-over bypass had been performed, the aneurysm was opened and its patent arterial branches were ligated with sutures. The fistula was then intra-aneurysmally sutured and covered with an omental flap. The diagnostic and therapeutic approaches to this severe complication are discussed with a review of the literature following the presentation of this case.

Recognition and management of patients with high-risk vesicovaginal fistulas: Implications for teaching and research

Vesicovaginal fistulas (VVFs) occurring as a result of obstetric trauma are a vast problem in Nigeria and Ghana, where at least 20 000 women await repair, and fewer than 50 physicians have the necessary expertise. Through a series of conferences those VVFs that are at high risk and those at low-risk for repair failure, were identified. A clinic was established where repair of low-risk VVFs was done on an ongoing basis in a remote region of Ghana. A visiting surgical team was utilized to repair the difficult, or high-risk, VVFs, which included 4–6 cm VVFs (3), recurrent VVF (1), combined VVF and RVF (rectovaginal fistula), a large 5 cm juxtacervical VVF (1), and a vesicouterine fistula (1). Management of these patients and others with VVF repair complications is discussed.     

TOTAL LARYNGECTOMY WITH PRIMARY VOICE RESTORATION

Forty-three patients were prospectively studied following tracheo-oesophageal puncture at the time of laryngectomy (primary voice restoration). Blom-Singer voice prostheses were used. The surgery was regarded as successful if a patient continued to use the voice prosthesis as the major means of communication with clear intelligibility 4 months after the operation. Using this criterion, the success in this series was 70%. No attempt was made to assess the quality of speech. Complications and causes of failure are discussed.

目的 探讨外伤性十二指肠损伤的处理及影响预后的因素。方法 对1992年1月至2002年月1月收治的32例外伤性十二指肠损伤病例的临床资料进行回顾性分析。结果 术前确诊19例(59．4％)，漏诊13例(40．6％)；治愈29例(90．6％)，死亡3例(9．4％)；发生并发症9例(28．1％)。十二指肠瘘是主要的并发症。结论 简单而合理的手术方式是治疗十二指肠损伤的重要措施。早期手术，有效的十二指肠减压和术后肠外营养是影响预后的主要因素。     

多层螺旋CT血管成像诊断颈动脉海绵窦瘘

目的探讨颈动脉海绵窦瘘(CCF)的解剖病理基础及螺旋CT血管成像(MSCTA)表现,提高MSCTA对CCF的诊断能力。方法12例经DSA证实的CCF均进行了螺旋CT平扫、增强扫描及血管成像重建。结果CCF的MSCT及CTA表现为:海绵窦扩大及眼上静脉扩张12例,并与颈内动脉同时显影;其他属支静脉扩张6例;对侧海绵窦扩大4例,与DSA检查结果一致。患侧眼球突出12例。颅底、眶壁骨折5例。眼球壁模糊、增厚5例。脑挫伤、出血4例。眼外肌增粗1例。结论螺旋CT及其血管成像诊断CCF简单、快捷、准确、可靠,特别是在外伤性CCF中,是首选的检查及诊断方法。     

MAGNETIC RESONANCE IMAGING FACILITATES ASSESSMENT OF PERIANAL CROHN'S DISEASE

Three illustrative cases of magnetic resonance imaging (MRI) in patients with perianal Crohn's disease are presented. Modern MRI techniques provided excellent visualization of perineal anatomy, inflammatory tissues and an anorectal stricture. It also allowed detailed delineation of the patho-anatomy of fistulous abscess and any communication to more proximal bowel. This report illustrates the potential of modern MRI as an important investigative adjunct in evaluating the anorectal manifestations of Crohn's disease.     

Postnephrectomy arteriovenous fistula of the renal pedicle treated with detachable balloons: A case report

A case of postnephrectomy arteriovenous fistula of the right renal pedicle is reported here. The diagnosis was confirmed by angiography, and successful treatment was achieved using detachable balloon.     

Ano-cutaneous flap repair for complex and recurrent supra-sphincteric anal fistula.

BACKGROUND: Suprasphincteric fistulae remain the most difficult to cure. OBJECTIVES: The purpose of this study was to evaluate the healing rate of suprasphincteric anal fistula treated by ano-cutaneous advancement flap repair, and the impact of this procedure on continence and quality of life. METHOD: Sixteen patients with complex, recurrent or chronic suprasphincteric fistulae associated with significant tissue damage (necrotizing fasciitis, keyhole deformity and anal stenosis) or who had failed previous surgical procedures were treated by ano-cutaneous flap closure. They were assessed pre and postoperatively by the treating surgeon for wound healing and fistula recurrence and later followed up by phone interview using the St Mark's Hospital incontinence score and the Perianal Disease Activity Index (PDAI) as indicators of treatment outcome. RESULTS: Fifteen patients had successful healing of their fistula with the cutaneous flap, with recurrence in only one. The most common short-term complications were minor graft site wound separation, which healed in all cases without intervention, and wound pain, which settled over time and was not associated with recurrence. Continence improved for almost 70% of the patients, with a significant reduction in St Mark's incontinence scores (t = 2.62, 15 d.f., P = 0.02). PDAI also decreased significantly (t = 7.55, 15 d.f., P < 0.001), demonstrating improvement in quality of life for most patients. CONCLUSION: Ano-cutaneous flap can achieve healing of complex and recurrent suprasphincteric anal fistula in patients who had previously failed at other forms of treatment thus improving their quality of life and continence.

Most cases of anal abscess are caused by anal fistula and invasion of the surrounding tissues by a mixed colonic flora. Treatment consists of excision of the abscess and, in case of fistula, fistulectomy. Primary anorectal and perianal forms of actinomycosis are very rare and caused by actinomyces, as ubiquitous anaerobics bacterium. We report a case of perianal actinomycosis. The patient had a short history of painless perineal induration without fever and leukocytosis with normal results at routine blood examination. After excision, sulfur granules drained from the cavity and pathological investigations indicated perianal actinomycosis. Appropriate surgery and antibiotic treatment healed the perianal infection. After exclusion of possible diagnoses such as Crohn’s disease, tuberculosis and malignant growths, the rare case of perianal actinomycosis should be considered in the differential diagnosis of painless perianal masses.
