[Adjuvant Surgery for Initially Unresectable Locally Advanced Pancreatic Cancer following Gemcitabine and S-1 Chemotherapy--A Case Report].

A man in his 60s was admitted with obstructive jaundice. A hypovascular tumor, 55 mm in diameter, was detected in the pancreas head on imaging. The superior mesenteric vein showed severe stenosis bilaterally and the roots of all branches were invaded by the tumor. The tumor was diagnosed as unresectable pancreatic cancer, and chemotherapy of gemcitabine and S-1 was administered, resulting in a remarkable reduction of the tumor size. Following 7 courses of chemotherapy, a subtotal stomach-preserving pancreatoduodenectomy was carried out. Microscopic examination revealed no residual cancer cells in the resected specimen, indicating that pathological complete remission was obtained. Although some reports suggest that surgical treatment for patients with initially unresectable pancreas cancer who show excellent response to chemotherapy may improve the prognosis, further studies are needed.

[Fibrin glue injection therapy with diluted thrombin for complicated postoperative fistulas following digestive surgery].

Fibrin glue injection is used for treating postoperative digestive fistulas; however, this method is not always successful, especially in cases of complicated fistulas. Generally, the fibrin glue coagulates immediately after application before it reaches the end of the fistulas. Based on the results of an in vitro study of tensile strength and coagulation time, we utilized fibrin glue injection therapy with diluted thrombin solution (× 30) for treating refractory postoperative complicated fistulas in 23 cancer patients. In 20 of these patients, the fistulas were successfully closed after an average of 2.0 treatment cycles. This simple method of fibrin glue injection with diluted thrombin is useful for treating complicated postoperative digestive fistulas.

[Surgical treatment for gall bladder cancer with a confluence stone-a case report].

The patient was a 71-year-old man. In September 2011, he experienced abdominal pain with high fever. Abdominal computed tomography (CT) diagnosed acute cholecystitis with a confluence stone (corlette classification type II). He underwent total cholecystectomy and placement of a T-tube in the main bile duct through the gall bladder duct. However, pathological investigations revealed gall bladder cancer in the neck and body part of the gall bladder, leading to a diagnosis of gall bladder adenocarcinoma(Gbn, Flat type, tub2, INF ß,pSS, pHinf0, pBinf1, pPV0, pA0, pT3) with a confluence stone. We suspected that the tumor was present in the common bile duct. Therefore, in October 2011, he underwent choledochectomy, resection of the liver bed, lymph node dissection, and choledocho-jejunostomy. Pathological findings revealed that the tumor was present in the common bile duct. He died 8 months after the last surgery because of recurrence of peritoneal metastasis.
