The recent use of single-port-access surgery in cholecystectomy and other abdominal surgeries has confirmed its safety and validity as a treatment option. However, few reports have described the use of complete single-port access surgeries in hepatectomy for neoplasms. The authors performed single-port laparoscopic hepatectomy (SLH) for eight patients (5(More)
The authors describe three anatomic variations, circumaortic, retroaortic left renal vein, and retropelvic tributary of the renal vein, in Japanese cadavers. The incidences and the clinical significances of these variations are discussed with a detailed review of the literature. The median incidences of circumaortic left renal vein (CLRV) were 7.0 % in(More)
A duct-to-mucosa pancreatojejunostomy is technically difficult to perform for a small main pancreatic duct after pancreatoduodenectomy. Our group applied the parachute technique to reconstruct and attach a small pancreatic duct to the jejunal mucosa. This method makes it very easy to position stitches on the posterior row of the anastomosis. It also allows(More)
Thus far, no ideal substitutions have been developed for completely replacing the extrahepatic bile duct (EHBD). We used a bioabsorbable polymer tube (BAPT) for the complete reconstruction of an EHBD in pigs. A 2-cm-long EHBD was resected from the duodenal side, and a 4-cm-long BAPT graft was implanted at that site. The animals were re-laparotomized at 1 or(More)
Anatomical position of the liver poses a difficulty in approaching the lesions using a laparoscopic approach. The patient was a 79-year-old man with a surgical history of laparoscopic sigmoidectomy for colon cancer and posterior segmentectomy of the liver for metastatic liver tumor. On admission, he presented with another liver tumor (diameter, 1.5 cm) in(More)
OBJECTIVES We developed a new classification system for branch perfusion patterns in acute aortic dissection and used it to retrospectively evaluate the perfusion status of whole aortic branches and to examine the effects of central aortic repair. METHODS Thirty-four consecutive patients with acute type A aortic dissection underwent emergent surgery at(More)
Earlier studies have investigated the suitability of various materials and autologous grafts for the repair of diaphragmatic defects. Our group investigated the feasibility of using an artificial diaphragm (AD) to repair wide diaphragmatic defects. Twelve pigs were laparotomized and, in each pig, a defect was fashioned by resecting a round 8-cm diameter(More)
Cardiac tamponade secondary to blunt cardiac injury is an extremely serious and life-threatening condition that the emergency physician is required to make definitive and appropriate management and resuscitation. Although blunt cardiac injury includes a wide spectrum of pathological conditions, cardiac tamponade due to blunt trauma is rarely seen because(More)
