[A case of synchronous cancer of the gall bladder, common bile duct, and the papilla of vater].

A 58-year-old man was diagnosed with liver dysfunction during a health exam and subsequently visited a doctor. Abdominal ultrasonography revealed space-occupying lesions in the gall bladder and bile duct, and he was hospitalized for further examination and treatment. Computed tomography (CT), endoscopic retrograde cholangiopancreatography (ERCP), and magnetic resonance cholangiopancreatography (MRCP) revealed double cancer of the gall bladder and bile duct with pancreaticobiliary maljunction (PBM), and we performed a pancreatoduodenectomy. Pathological examination revealed gall bladder and bile duct cancer, and severe dysplasia of the papilla of Vater. We diagnosed synchronous triple cancer because none of the cancers had continuity or vascular invasion. Each cancer was at Stage I, and the patient has survived for 2 years and 6 months without recurrence and no additional treatment. PBM is a mutation of the junction of the pancreatic and bile ducts outside of the duodenal wall, and is a known complication of biliary tract cancer due to the reflux of pancreatic juice and bile. Because K-ras and p53 gene mutations occur in the biliary tract mucosal epithelium, PBM increases the risk of developing multicentric cancer. It is important to consider the existence of double cancer when biliary tract cancer is detected in a PBM patient.

[A case of postpancreaticoduodenectomy local recurrence successfully treated with extended resection].

A 68 -year-old man underwent a pancreaticoduodenectomy after being diagnosed with primary duodenal cancer. The postoperative pathological diagnosis was tub2, SE, ly1, v1, panc3, pn+, N0. Although adjuvant chemotherapy was administered, local recurrence in the portal region was detected 18 months later. The recurrent tumor pressed against the region of the bile duct anastomosis, which caused obstructive jaundice. After serum bilirubin levels were reduced, resection of the recurrent tumors was performed. This required resection of the transverse colon, parts of the portal vein, and the inferior vena cava. The bile duct anastomotic region, which had been infiltrated by the tumor, was excised and rebuilt. The postoperative pathological diagnosis was tub2. The patient continued to receive adjuvant chemotherapy and showed no signs of recurrence 9 months after surgery. Extended resection for local recurrences of primary duodenal cancer may be an effective means of disease control.

Surgical outcome of lumbar fusion surgery in patients with Parkinson disease.

STUDY DESIGN: Retrospective study. OBJECTIVES: To investigate the overall surgical outcome of lumbar fusion surgery in patients with Parkinson disease (PD). SUMMARY OF BACK GROUND DATA: Poor bone quality and muscular dysfunction are important clinical manifestations connected with musculoskeletal diseases in PD patients. These secondary changes caused by PD often result in spinal pathology, indicating spine operations for some patients with scoliosis, kyphosis, osteoporotic fracture, or degenerative spondylosis. However, little is known about the surgical outcome or prognosis of spine surgery in PD patients. METHODS: Lumbar fusion surgery was performed on 20 patients who had PD and degenerative spinal diseases. At the time of lumbar fusion surgery, the mean duration of PD, age, sex, the preoperative visual analog pain scale (VAS, 0 to 100 mm) for low back pain, Hoehn and Yahr staging, and other comorbidities were evaluated. Patients' postoperative clinical outcome was measured using the criteria of Kim and Kim and VAS for back pain. Radiographic assessment was made using plain films and a dynamogram. RESULTS: At the time of the spine surgery, Hoehn and Yahr staging of PD was from 1 to 2 in all patients. Only 1 patient had a satisfactory outcome; a good result according to Kim and Kim's criteria. The average postoperative VAS (mm) was 55.2, whereas the mean preoperative VAS (mm) was 53.9. Radiological assessment showed fusion status in 15 patients and probably no solid fusion mass in 5 patients. CONCLUSIONS: A poor surgical outcome would be inevitable because of the worsening of symptoms owing to the natural history of PD. Therefore, our current study suggested surgical indication should be exercised cautiously in the patients with PD and spinal stenosis.
