Percutaneous cholecystostomy using a central venous catheter is effective for treating high-risk patients with acute cholecystitis.

Percutaneous cholecystostomy (PC) using a pigtail catheter is performed on high-risk patients with acute cholecystitis as their general condition does not usually allow them to undergo a "definite" cholecystectomy. However, this method of PC is time-consuming and expensive and requires an interventional radiologist and specially designed radiologic equipment. To determine whether another PC approach was viable, we retrospectively compared patients who underwent PC using a central venous catheter (group A, n = 15) with those who underwent standard pigtail catheter PC (group B, n = 29). The waiting time prior to undergoing the PC was 1.8 days in group A and 3.5 days in group B (P < 0.05). The cost per patient was 293,364 won (254.44 dollars) for group A, and 438,719 won (380.50 dollars) for group B (P < 0.05). There were 4 complications in group A and 5 in group B. Following PC, 7 patients in group A and 15 patients in group B underwent delayed definite cholecystectomy, and there were no differences between these groups in terms of complications, mortality, and the delayed definite cholecystectomy surgical method. We conclude that in combination with careful patient selection, PC using a central venous catheter in high-risk patients with acute cholecystitis is a viable alternative to pigtail catheter PC.

Preoperative chemoradiation and pancreaticoduodenectomy with portal vein resection for localized advanced pancreatic cancer.

Pancreatic adenocarcinoma is a common disease that is rarely cured. Surgical resection remains the only treatment modality that has a curative potential, although the majority of patients are unsuitable for resection at the time of diagnosis. Chemoradiation therapy prior to a pancreaticoduodenectomy ensures that a patient who undergoes a complete resection multimodality therapy, avoids a resection in patients who have a rapidly progressive disease, and allows radiation therapy to be given to well oxygenated cells before, surgical devasculation. This permits the chance of resection of an unresectable pancreatic cancer by downstaging. A patient with cytologic proof of localized adenocarcinoma of the pancreatic head received an intravenously chemoradiation (Taxol, 50 mg/m2 intravenously for 3 hours week on 5 cycles, of Gemcytabine 1000 mg/m2/day intravenously for 3 days week on 2 cycles, of 4500 cGy) with the intention of proceeding to a resection operation, restaging was performed by computed tomography, magnetic resonance imaging from 5 weeks every months due to ongoing decreasing of tumor size after the chemoradiation. At laparotomy, the patient didn't have suspected metastatic disease, the tumor size was 2 X 3 cm on the pancreas head and was infiltrating into the portal vein for about 3 cm length on right side. A pancreaticoduodenectomy along with a portal vein and superior mesenteric vein resection was done and then reconstruction of a vascular anastomosis by using the right side of the internal jugular vein. Perioperative complications didn't occur. In conclusion, preoperative chemoradiation of a localized advanced pancreatic tumor has no added risk to the operative complications and the prospects for resectability are enhanced.

Metastatic renal cell carcinoma of the gallbladder.

Metastatic renal cell carcinoma is renowned for its potency to spread to almost any organ of the body; however metastasis to the gall bladder is very rare. We present a case of a 48 year old man who initially demonstrated renal cell carcinoma, and in who gallbladder metastasis was later detected. A review of the literature revealed only a small number of cases of renal cell carcinoma metastasizing to the gallbladder, and these were primary found upon necropsy. Gallbladder metastasis in this case was detected clinically.
