OBJECTIVE The authors evaluated the rationale for and feasibility of gastroduodenal artery preservation in pylorus-preserving pancreatoduodenectomy (PPPD) for periampullary cancer in which the pancreatic remnant maintains a normal function and morphologic characteristics. SUMMARY BACKGROUND DATA Pylorus-preserving pancreatoduodenectomy has become one of(More)
BACKGROUND/AIMS Recent advances in the surgical anatomy of the pancreatoduodenal region have permitted duodenum-preserving pancreatic head resection. However, pancreas-sparing duodenectomy (PSD) has not been systematically studied and various types of such procedures have been reported under the designation of PSD. METHODOLOGY PSD was performed in 6(More)
Choroideremia (CHM), an X-linked recessive hereditary disease, is an intractable chorioretinal dystrophy. The rate of disease progression of CHM reportedly shows considerable variability. A number of mutations involving the gene that codes for Rab escort protein-1 (REP-1) have been detected in CHM patients. We have analyzed REP-1 gene mutations of Japanese(More)
Although hand-assisted laparoscopic surgery (HALS) is very common in various laparoscopic procedures, it is rarely used for retroperitoneal endoscopic adrenalectomy because of the small working area. The authors evaluate HALS in endoscopic adrenalectomy with respect to its use as a rescue procedure in complicated cases. In their department, 47 patients(More)
We performed a hand-assisted laparoscopic resection of the distal stomach for treatment of gastric cancer with use of an abdominal wall-lift method. The surgeon's left hand, which was inserted through a right lower quadrant incision, was extremely useful in accomplishing D2 lymph node dissection, application of a pursestring instrument, and approximation of(More)
INTRODUCTION Laparoscopic splenectomy using pneumoperitoneum has been performed since 1992. The gasless abdominal wall-lifting method for laparoscopic splenectomy was introduced as an alternative. This retrospective study was undertaken to compare results using the two techniques. METHODS Between 1995 and 2010, 54 patients underwent laparoscopic(More)
INTRODUCTION Cryptorchidism is common in children but is rare in the elderly. It often presents with a constellation of signs and symptoms similar to routine inguinal hernias. We present the case of an elderly man with cryptorchidism containing a Leydig cell tumor and provide clinical insights. PRESENTATION OF CASE An-84-year old man was admitted with an(More)
INTRODUCTION Gastric volvulus is torsion of the stomach and requires immediate treatment. The optimal treatment strategy for patients with gastric volvulus is not established, because of significant variations in the cause and clinical course of this condition. PRESENTATION OF CASES We describe our experience with six elderly patients with gastric(More)
We report a case of benign intracranial hypertension (BIH) resulting from corticosteroid withdrawal. A 36-year-old woman was admitted to hospital because of an intractable headache. A neurological examination on admission showed no abnormalities other than a headache and nausea. CT, MRI, and angiogram examinations showed no abnormalities. Hematological and(More)
