Cystic duct with no visible signal on magnetic resonance cholangiography is associated with laparoscopic difficulties: an analysis of 695 cases.

Background/aims: We investigated the association between the magnetic resonance cholangiography (MRC) results and surgical difficulties and bile duct injuries during laparoscopic cholecystectomy (LC).

Methods: MRC was performed on 695 consecutive patients before LC. We divided the patients into two groups (visible cystic duct group and "no signal" cystic duct on MRC group) and compared them with regard to the length of the operation, conversion rate to open cholecystectomy (OC) and rate of bile duct injury.

[Two resected cases of pulmonary metastasis from post operative colorectal cancer after preoperative chemotherapy with FOLFOX].

Unlabelled: We described two resected cases of pulmonary metastasis from postoperative colorectal cancer after preoperative FOLFOX chemotherapy. Pathologic histology inspection of the tumor was judged to be effective prior to resection. The first case is a 68-year-old male who underwent a sigmoidectomy as a stage III A sigmoid colon cancer in March 2003.

[Carboplatin and CPT-11 chemotherapy in a hemodialysis patient with small-cell lung cancer].

We administered a dose-down chemotherapy, which was a combination of carboplatin 100 mg/body (AUC 3.0, day 1) and CPT-11 30 mg/m2 (day 1, day 15) to the patient with a poor performance status of extensive small-cell lung cancer with renal failure. Hemodialysis was performed two hours after the chemotherapy.

[Evaluation of bronchial arterial infusion (BAI) for lung cancer with carcinomatous pleuritis].

Materials And Methods: Six high-risk patients of lung cancer with carcinomatous pleuritis to which BAI was done were examined. BAI was performed using CDDP (40-50 mg/m2) + CPT-11 (40-50 mg/m2). The therapeutic effects, side effects, a reduction of the symptoms and prognosis were examined.

High molecular weight form insulin-like growth factor II-producing mesenteric sarcoma causing hypoglycemia.

An 81-year-old woman presented with frequent episodes of hypoglycemia. Her serum level of insulin was normal, but her serum insulin-like growth factor (IGF)-II level was high. She was found to have a spindle cell sarcoma originated from the mesentery of the sigmoid colon, which was completely resected.

A crescent-shaped sparing proximal to a liver tumor may indicate underlying portal tumor thrombus.

A primary or metastatic liver tumor sometimes blocks portal venous flow and causes a focal sparing in the fatty liver. We herein report a case of segmental sparing due to the portal tumor thrombus extending from the metastatic liver tumor. The present case demonstrates characteristic computer-associated tomographic findings, a distal oval hypodense tumor with proximal "crescent-shaped sparing", which may indicate underlying portal tumor thrombus at the apex of the sparing.
