Treatment of ureteroarterial fistula with an endoureteral stent graft.

A patient with a history of total cystectomy for bladder cancer, cutaneous ureterostomy, irradiation, and long-term indwelling urinary catheters presented with an aortoureteral fistula (UAF), which was treated with an endoureteral stent graft. The described ureteral approach using stent grafts may be considered for the management of UAFs when more traditional approaches are unavailable.

[Two cases of gastric endocrine cell carcinoma].

Gastric endocrine cell carcinoma is rare and associated with a poor prognosis. The first case was a man in his sixties with gastric endocrine cell carcinoma, of which a clinical finding was T2N1M0H1 (Stage IV). S-1 + CDDP therapy was selected and failed.

Correction of anophthalmic enophthalmos with a three-staged procedure: two case reports.

Surgical correction of an anophthalmic enophthalmos secondary to inappropriate repair of the eye socket involves several difficult aesthetic issues associated with long-term use of a poorly fitting prosthetic eye. In this paper, we present two cases of anophthalmic enophthalmos. During the treatment of the first patient, unsatisfactory cosmetic problems including lower eyelid retraction, hypoglobus, and severe upper eyelid ptosis were revealed.

Spindle cell hemangioendothelioma of the temporal muscle resected with zygomatic osteotomy: a case report of an unusual intramuscular lesion mimicking sarcoma.

Spindle cell hemangioendothelioma (SCH) was originally described by Weiss and Enzinger (1986) as a low-grade angiosarcoma resembling both cavernous hemangioma and Kaposi's sarcoma. Recent studies suggest that SCH is a benign neoplasm or reactive lesion accompanying a congenital or acquired vascular malformation. Most SCHs present as one or more nodules affecting the dermis or subcutis of the distal extremities.

Advanced epithelioid malignant peripheral nerve sheath tumor showing complete response to combined surgery and chemotherapy: a case report.

Malignant peripheral nerve sheath tumor (MPNST) is a rare high-grade soft tissue sarcoma. The epithelioid variant accounts for 5% or less of MPNSTs; the clinical behavior of this variant is unclear. Reports of approximately 40 cases are available in the English literature; however, most reports addressed clinicopathological features rather than therapeutic procedures or clinical courses.

Scaphoid dislocation associated with axial carpal dissociation during volar flexion of the wrist: a case report.

We present the first report of a patient with an isolated scaphoid dislocation with axial carpal dissociation sustained during volar flexion of the wrist. The scaphoid was dislocated to the radial side of the radial styloid process and was slightly shifted to the dorsal side. It was shown that the position of the wrist played an irrelevant role for occurring scaphoid dislocation.

[Expandable metallic stent treatment for obstructive colorectal cancer patients].

Unlabelled: The expandable metallic stent (EMS) have been used to treat obstructive colorectal cancer. We used EMS in 13 out of 14 cases of obstructive colorectal carcinoma patients (insertion rate 93%). Of these 13 cases, 6 cases were male patients, and 7 cases were female patients.

Radiation therapy and photodynamic therapy for biliary tract and ampullary carcinomas.

The purpose of radiation therapy for unresectable biliary tract cancer is to prolong survival or prolong stent patency, and to provide palliation of pain. For unresectable bile duct cancer, there are a number of studies showing that radiation therapy is superior to the best supportive care. Although radiation therapy is used in many institutions, no large randomized controlled trials (RCTs) have been performed to date and the evidence level supporting the superiority of this treatment is low.

Pancreatic metastasis of malignant melanoma diagnosed by EUS-guided fine needle aspiration (EUS-FNA).

Pancreatic metastasis of malignant melanoma is rarely diagnosed while the patient is alive. We report a case of metastatic melanoma of the pancreas in a 35-year-old woman presenting with a solid mass of the pancreas. Her past medical history included a radical hysterectomy 2 years previously for malignant melanoma of the vagina.

[Percutaneous transhepatic central venous port implantation via the middle hepatic vein: a case report].

Percutaneous transhepatic central venous access with a subcutaneous infusion port was performed in a 34-year-old woman with extensive third-degree burns whose peripheral vessels were not available because of infection or dermatoplastic sites. This procedure could be done in the same way as the usual PTCD maneuver without serious complications. The infusion system functioned well, and the patient's alimentation could be carried out.

Temporary use of an accuflex stent for unextractable common bile duct stones.

Endoscopic management has become the main therapeutic approach for the extraction of common bile duct (CBD) stones, and successful removal can be achieved in 80-90% patients using conventional balloon and basket techniques. However, if it is difficult to completely fragment a stone, or to clear the CBD, which may occur for a variety of reasons, the therapeutic problem will remain. When bile duct stones can not be removed, a viable management option is to place a biliary stent to ensure drainage.

[Management of hilar bile duct carcinoma with high-dose radiotherapy and expandable metallic stent placement].

This article describes our experience with high-dose radiotherapy in combination with the placement of expandable metallic stents (EMS) in the management of hilar bile duct carcinoma. Between 1988 and 1999, 107 consecutive patients with hilar bile duct carcinoma were treated with EMS placement either alone or in combination with high-dose radiotherapy. External beam radiotherapy (EBRT) was indicated in 101 patients, and in 86 this was combined with intraluminal 192Ir irradiation (ILRT, 59-98Gy).

Successful treatment of immunoblastic lymphadenopathy-like T-cell lymphoma with cyclosporin A.

Immunoblastic lymphadenopathy (IBL)-like T-cell lymphoma is considered to belong to peripheral T-cell lymphoma. Its prognosis is grave and effective treatments have not been established. Recently, we gave oral cyclosporin A (CsA) to a patient with IBL-like T-cell lymphoma, and succeeded in achieving dramatic remission.

Case report: mucinous cholangiocarcinoma featuring a multicystic appearance and periportal collar in imaging.

A case of mucinous cholangiocarcinoma (CC), a rare histological type of CC, featuring unusual images is reported. The patient was hospitalized because of acute development of jaundice and fever. Computed tomography demonstrated multiple cystic lesions in the liver and a band-like low density area parallel to the intrahepatic portal vein, a so-called 'periportal collar'.

[Children's anxiety is reduced by the presence of parents at induction of anesthesia].

The present study aims to examine if children's anxiety could be reduced by the presence of the parent at induction of anesthesia. The subjects were children aged from 6 months to 6 years who underwent general anesthesia. Forty children (Group A) received premedication and without the parent at induction of anesthesia.

[Intraoperative anaphylaxis caused by latex surgical gloves].

A 17-year-old male encountered anaphylaxis caused by latex surgical gloves during emergency surgery under general anesthesia. He had undergone multiple surgical procedures, bladder catheterization and was suffering from atopic dermatitis. The patient developed bronchospasm and circulatory collapse 20 minutes after the start of surgery.

Durable remission after splenectomy for Waldenström's macroglobulinemia with massive splenomegaly in leukemic phase.

A patient with M-proteinemia (IgM, kappa type), lymphocytosis, anemia, and massive splenomegaly, was diagnosed as having Waldenström's macroglobulinemia (WM). Since this case was refractory to chemotherapy, splenic irradiation was performed, which effectively reduced the serum IgM level, spleen size, and lymphocyte counts; however, its effect was transient. Splenectomy was then carried out.

[Significance of PUVA therapy for adult T-cell leukemia/lymphoma--PUVA therapy can induce apoptosis in leukemic cells].

PUVA therapy is known to be effective for treating cutaneous T-cell lymphoma (CTCL). Considering that adult T-cell leukemia/lymphoma (ATL) represents a T-lymphocytic proliferative disorder similar to CTCL, it is likely that PUVA therapy is effective for treating ATL. We applied PUVA therapy to a 53 year old man with acute (i.

[Evaluation of early colorectal cancer with submucosal invasion based on histological architecture].

To clarify the clinicopathological features of tumors with submucosal invasion, especially superficial elevated and sessile ones, histological architectures of 32 cases of submucosal invasive cancers were analyzed. They were classified into 3 types based on cross-section view: PG and NPG of Shimoda's classification and PG'. Histological architectures were drawn in accordance with these findings.
