The aim of this article is to propose new criteria for the diagnosis and severity assessment of acute cholecystitis, based on a systematic review of the literature and a consensus of experts. A working group reviewed articles with regard to the diagnosis and treatment of acute cholecystitis and extracted the best current available evidence. In addition to(More)
BACKGROUND Laparoscopic cholecystectomy is now accepted as a surgical procedure for acute cholecystitis when it is performed by an expert surgeon. There are several lines of strong evidence, such as randomized controlled trials (RCTs) and meta-analyses, supporting the introduction of laparoscopic cholecystectomy for patients with acute cholecystitis. The(More)
BACKGROUND The Tokyo Guidelines for the management of acute cholangitis and cholecystitis (TG07) were published in 2007 as the world's first guidelines for acute cholangitis and cholecystitis. The diagnostic criteria and severity assessment of acute cholecystitis have since been widely used all over the world. A validation study of TG07 has shown that the(More)
Protein tyrosine phosphatases (PTPases), such as SHP-1 and SHP-2, that contain Src homology 2 (SH2) domains play important roles in growth factor and cytokine signal transduction pathways. A protein of approximately 115 to 120 kDa that interacts with SHP-1 and SHP-2 was purified from v-src-transformed rat fibroblasts (SR-3Y1 cells), and the corresponding(More)
Acute pancreatitis is a common disease with an annual incidence of between 5 and 80 people per 100,000 of the population. The two major etiological factors responsible for acute pancreatitis are alcohol and cholelithiasis (gallstones). The proportion of patients with pancreatitis caused by alcohol or gallstones varies markedly in different countries and(More)
Since its publication in 2007, the Tokyo Guidelines for the management of acute cholangitis and cholecystitis (TG07) have been widely adopted. The validation of TG07 conducted in terms of clinical practice has shown that the diagnostic criteria for acute cholecystitis are highly reliable but that the definition of definite diagnosis is ambiguous.

BACKGROUND/PURPOSE The results from the Japanese Biliary Tract Cancer Statistics Registry from 1988 to 1998 were reported in 2002. In the present study, we report here selectively summarized data as an overview of the 2006 follow-up survey of the registered cases from 1998 to 2004 for information bearing on problems with the treatment of cancer of the(More)
BACKGROUND The value of pancreatoduodenectomy (PD) with extended lymphadenectomy for pancreatic cancer has been evaluated by many retrospective studies and 3 randomized controlled trials (RCT). However, the protocols used and the results found in the 3 RCTs were diverse. Therefore, a multicenter RCT was proposed in 1998 to evaluate the primary end point of(More)
BACKGROUND Pancreatogastrointestinal anastomosis is the most important anastomotic method of reconstructing the digestive tract following pancreaticoduodenectomy. METHODS We therefore conducted a survey on pancreatogastrointestinal anastomosis at the 28th Japan Pancreatic Surgery Club in 2001. RESULTS Results revealed that of the methods of(More)
