11/61. Stent migration necessitating surgical intervention.

    BACKGROUND: Internal drainage with transhepatically or endoscopically placed endoprostheses has been used for many years as a temporary or definitive treatment for biliary tract obstruction. As a late complication, stent migration may occur. methods: We reviewed our records to identify patients who were operated on for a migrated endoprosthesis that was causing complications. In all, five such patients were identified. RESULTS: One patient had a large bowel perforation. Bowel penetration led to an interenteric fistula in one patient and to a biliocolic fistula formation in another. Small bowel distension was found in two patients. Surgical treatment consisted of local excision in three patients, segmental resection in one patient, and a bypass operation in the patient with biliocolic fistula. Postoperatively, four patients recovered without problems, but one patient died during a complicated postoperative course. CONCLUSION: If a stent becomes stuck in the gastrointestinal tract and is not accessible for endoscopic removal, early operative revision is mandatory to prevent further complications.

12/61. Presentation of idiopathic retroperitoneal fibrosis in the pediatric population.

    Idiopathic fibrosis of the retroperitoneum is rare in childhood. The authors describe an 11-year-old boy who presented with progressive renal failure, bilateral hydronephrosis, hypertension, and elevated erythrocyte sedimentation rate (ESR) owing to retroperitoneal fibrosis. Ureterolysis was performed with improvement in his creatinine level and blood pressure. The soft tissue mass consisted of dense collagenous fibers consistent with retroperitoneal fibrosis. Postoperatively, he received steroids and azathioprine. retroperitoneal fibrosis in the pediatric population is rare with only 23 cases reported in the English-language literature. Treatment includes pulsed steroid regimens, ureteral catheterization, and retroperitoneal exploration with ureterolysis. If allowed to progress, renal failure can result and lead to death. The etiology of retroperitoneal fibrosis in the pediatric patient may include autoimmune diseases, infection, and neoplasm, but most cases are idiopathic. retroperitoneal fibrosis should be considered in patients with an elevated ESR, hypertension, renal failure, and hydronephrosis. Evaluation also should include a search for autoimmune diseases and malignancy.

14/61. Surgical potpourri.

    Six unusual surgical case are reported and the literature reviewed. The cases are: 1. Adenoid cystic carcinoma of the submaxillary gland 2. Parathyroid carcinoma 3. Squamous cell cancer of the pancreas 4. leiomyosarcoma of the abdomen (two cases) 5. myelolipoma of the adrenal gland These are representative cases from a general surgeon's practice, emphasizing the variety of interesting patients that the general surgeon cares for, and the scope of surgical knowledge that must be continually maintained. One of the attractions of having a practice in general surgery is that it provides the opportunity to diagnose and treat patients with a variety of conditions requiring surgical intervention. Reviewed here are six recent operative cases, their presentation, and management.

15/61. Fine needle aspiration.

    Fine needle aspiration (FNA) has been widely used as a diagnostic tool for the past half century. Differing from large bore cutting needle biopsy, FNA utilizes 22- to 27-gauge needles. The cell samples aspirated from a lesion are characteristically smeared on glass slides for immediate microscopic evaluation. An adequacy report and a preliminary diagnostic impression are rendered in approximately 10 to 15 minutes. A final report is generally rendered within 24 hours. The method has been used as one of the most cost-effective, complication-free, and rapid techniques for preoperative investigation of tumors and tumor-like conditions. Its usefulness in the diagnosis and management of oncology patients is emphasized in this article.

16/61. The cytology of pediatric masses: a differential diagnostic approach.

    In the united states, fine-needle aspiration biopsy (FNAB) and other cytodiagnostic methods have been underutilized in the evaluation of masses in the pediatric age group. Cytopathologists and cytotechnologists are therefore relatively unfamiliar with the cellular features of lesions that occur in children. On the basis of the cytologic findings from 64 pediatric cases, including 56 FNABs and 8 intra-operative imprints, a differential diagnostic approach to lesions in this age group is presented. The majority of cases can be placed into 1 of 5 cytomorphologic categories: (1) round-cell pattern, (2) mixed inflammatory pattern, (3) spindle-cell pattern, (4) epithelial pattern, and (5) cystic pattern. Once a cytomorphologic category is determined, evaluation for unique cellular features, special studies, and clinical correlation allows a specific diagnosis to be made in most cases. Pitfalls in pediatric cytopathology are illustrated by discussion of the following cases: a renal Burkitt's lymphoma mimicking a Wilms' tumor, a traumatic neuroma masquerading as a recurrent malignant schwannoma, Langerhans-cell histiocytosis resembling granulomatous inflammation, and a cystic granuloma that mimicked a branchial cleft cyst. Consideration of these problems and use of the recommended diagnostic approach will aid in interpretation in this difficult area.

17/61. Neuropathological findings after continuous intrathecal administration of S( )-ketamine for the management of neuropathic cancer pain.

    Questions have been raised about the potential neurotoxicity of the neuraxial use of ketamine although ketamine and its active enantiomer S( )-ketamine have been used intrathecally and epidurally (caudally) for the management of perioperative pain and in a variety of chronic pain syndromes. Clinical experience following neuraxial administration of S( )-ketamine has been documented without reference to local central nervous system toxicity following this approach. In addition, there are no preclinical safety data regarding stability, compatibility, and neurotoxicity on intrathecal use of single S( )-ketamine or combinations of S( )-ketamine, morphine, bupivacaine, and clonidine. In the present case, the continuous intrathecal administration of S( )-ketamine, in combination with morphine, bupivacaine, and clonidine resulted in adequate pain relief in a patient suffering from intractable neuropathic cancer pain. However, postmortem observation of the spinal cord and nerve roots revealed severe histological abnormalities including central chromatolysis, nerve cell shrinkage, neuronophagia, microglial upregulation, and gliosis. Based on our results, neuraxial administration of S ( )-ketamine cannot be recommended for clinical practise before a systematic study of toxicology of neuraxial S( )-ketamine in animals or humans has been performed.

18/61. Kimura's disease: an unusual cause of cervical tumor.

    Kimura's disease (KD) is an angiolymphoid proliferative disease of soft tissue with peripheral blood eosinophilia and elevated serum immunoglobulin (Ig) E. The treatment options range from conservative observation for the asymptomatic patient to surgical excision, steroid therapy and radiotherapy for symptomatic patients. Surgical excision is the most common diagnostic measure and is the treatment of choice. A case of KD in a 13-year-old Malay girl is presented. Clinically there was painless right jugular digastric mass measuring 3cm by 3cm. Her blood investigation showed pronounced eosinophilia. She underwent excision biopsy uneventfully. The biopsy from the swelling showed reactive follicular hyperplasic with prominent eosinophilia. There was no evidence of malignant change. Postoperatively after 3 years follow up, she was asymptomatic and no signs of tumor recurrence.

19/61. Cotyledonoid dissecting leiomyoma of the uterus: a case report of a benign uterine tumor with sarcomalike gross appearance and review of literature.

    Cotyledonoid dissecting leiomyoma (Sternberg tumor) is a very rare variant of uterine smooth muscle tumor with an unusual and alarming gross appearance. Including our case, approximately 20 cases were reported in the literature. A 27-year-old woman presented with pelvic mass. A 41-cm fungating rubbery mass with placenta-like appearance adhering to the posterior uterine surface and extending to the left broad ligament and pelvic cavity was observed. An intraoperative frozen section was requested, and a diagnosis of a benign smooth muscle tumor was given. Total abdominal hysterectomy and bilateral salpingo-oophorectomy were performed with removal of the pelvic tumor extension. Thorough tumor sampling was performed and showed nodules of interlacing bundles of bland-looking smooth muscle cells, separated by expanded, edematous, and highly vascularized stroma. No atypia, mitotic activity, or coagulative necrosis was seen. Immunohistochemical studies confirmed the smooth muscle nature of the tumor. Cotyledonoid leiomyoma has a distinctive gross appearance which usually raises the suspicion of sarcoma. Intraoperative frozen section is a mandatory and helpful procedure to avoid overtreatment of such cases.

20/61. Follow-up study on metastatic cerebellar tumor surgery--characteristic problems of surgical treatment.

    Recently, the incidence of metastatic cerebellar tumors has increased. The authors operated on 12 cases of metastatic cerebellar tumors, with total or subtotal removal of nodules in brain metastases. Surgical complications observed as a result of postoperative investigation are presented. 1) Some cases developed carcinomatous meningitis within a short period. During removal of a tumor on the superior cerebellar surface attention should be paid to the prevention of dissemination to the cerebral cisterns adjacent to the tumor. 2) Some cases demonstrated peritoneal metastasis probably due to dissemination via the ventriculoperitoneal shunt tube, suggesting that great care should be taken during a shunt operation after removal. 3) Both carcinomatous meningitis occurring after removal and remote metastasis via the shunt tube were related to recurrence after removal of the cerebellar metastatic lesion, raising the issue of whether or not total macroscopic removal should be included in the indications for surgical treatment of cerebellar metastasis. Those cases in which surgery is indicated should also be routinely treated by postoperative irradiation.
