Ontogenetic appearances of glucagon, insulin and tyrosine hydroxylase (TH) were immunohistochemically investigated on developing pancreatic islets of rats. Glucagon immunoreactivity appeared first in some epithelial cells (g-cells) of the dorsal anlage of the pancreas on day 11.5 of gestation. On day 12.5, g-cells increased in number manufacturing the(More)
To evaluate the efficacy and outcome of laparoscopic subtotal cholecystectomy (LSC) for patients with severe cholecystitis. Between April 1992 and May 2008, 1226 patients underwent laparoscopic cholecystectomy (LC). From 2000 onward 60 patients with severe cholecystitis underwent LSC. The outcomes of LC were compared between patients who underwent the(More)
Laparoscopic major hepatectomy (LMH) is an innovative procedure that is still in the exploration phase. Although new surgical techniques have learning curves, safety should be maintained from the onset. This retrospective study was conducted to evaluate the safe introduction of LMH. We retrospectively reviewed data from 245 consecutive patients who(More)
Between March and April 2009, three consecutive patients underwent single-incision laparoscopic gastric wedge resection for a submucosal tumor located in the anterior wall or greater curvature of the stomach. First, we placed two or three trocars through the same infra-umbilical skin incision. Then, we either elevated the tumor with a mini-loop retractor or(More)
Non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) are increasingly common cause of chronic liver disease worldwide. The diagnosis of NASH is challenging as most affected patients are symptom-free and the role of routine screening is not clearly established. Most patients with severe obesity who undergo bariatric surgery have(More)
We studied pancreatic exocrine function in response to cerulein and carbamylcholine in isolated perfused pancreas obtained from control, streptozotocin-induced diabetic, and insulin-treated diabetic rats. The time course of pancreatic juice, protein, amylase, and trypsinogen secretion in response to cerulein or carbamylcholine in diabetic rats was similar(More)
Between March 2003 and March 2007, three patients with benign pancreatic tumors underwent a planned laparoscopic spleen-preserving distal pancreatectomy with conservation of the splenic artery and vein. Four trocars were placed, and an endoscopic linear stapler was used to transect of the pancreas. The perioperative data and surgical outcomes were examined.(More)
Portal plasma immunoreactive secretin (IRS) concentrations, pancreatic juice flow, and amylase output were simultaneously measured in response to intraduodenal infusion of 1-phenyl-1-hydroxy-n-pentane (PHP), as well as infusion of hydrochloric acid (HCl). These data were compared with those obtained from intravenous bolus injections of synthetic porcine(More)
Single-port laparoscopic cholecystectomy (SPLC) is an emerging technique and gaining increased attention by its superiority in cosmesis. A 1.5-cm vertical transumbilical incision is used for the single port, followed by the glove method. Indications for SPLC are the same as those for standard 4-port laparoscopic cholecystectomy, including patients with(More)
The effect of orally administered ornoprostil, 17S,20-dimethyl-6-oxoprostaglandin E1 methyl ester, on gastric emptying and on pancreatic polypeptide (PP) release after solid meal ingestion, was investigated in man. A radionuclide technique was used to measure gastric emptying of eight healthy volunteers. In addition, four parameters [SI (starting index):(More)
