Progressive and irreversible, chronic pancreatitis is characterized by repeated episodes of acute inflammation over a long Doxorubicin concentration period, leading to digestive and absorptive disorders by destruction
of the exocrine pancreas and to diabetes mellitus by destruction of the endocrine pancreas. Attention has been called to “early chronic pancreatitis” to encourage diagnosis and treatment before effective therapy becomes difficult. We discuss our experience with treatment of pancreatolithiasis and ductal stenosis. We also describe the new concept of early chronic pancreatitis. About 47 000 patients in Japan have chronic pancreatitis, including some 35 000 (75%) with pancreatolithiasis. The male-to-female ratio among patients with chronic pancreatitis is 4.4:1. The most common etiology is alcoholism (77.8%) in men and idiopathic (47.6%) in women. The mean life expectancy of patients with chronic pancreatitis is about 10 years shorter than that of healthy
people. The main cause of death is malignant tumors or complications such as renal failure related to diabetes mellitus. The course of chronic pancreatitis includes two phases: a compensated phase where symptoms such as abdominal pain, back pain, and anorexia occur repeatedly; and a decompensated phase characterized by digestive and absorptive disorders such as steatorrhea and diarrhea (exocrine insufficiency), and secondary diabetes mellitus (endocrine insufficiency). this website When complications such as pancreatolithiasis and pseudocyst occur, elevated
pancreatic ductal pressure exacerbates pain and induces other complications, resulting in a worse clinical condition; treatment of these complications therefore is essential. Treatment see more of pancreatolithiasis includes procedures such as pancreatic sphincteroplasty, pancreaticojejunostomy,[3, 4] and often more extensive operation such as pancreatic resection and duodenum-preserving pancreatic head resection. As for endoscopic treatment, Inui et al. reported endoscopic pancreatic sphincterotomy in 1983, while Fujii et al. reported pancreatic duct stenting in 1985. Long-term outcome of surgery is recognized to be superior to that of endoscopic treatment in patients with painful obstructive chronic pancreatitis.[9, 10] Cahen et al. reported that almost half of patients treated with endoscopy eventually underwent surgery. However, endoscopic treatment (Figs 1-4) can be offered as a relatively non-invasive first-line treatment, with subsequent recourse to surgery in cases of failure and/or recurrence. Although surgical and endoscopic treatments remain the conventional therapies for pancreatolithiasis, usefulness of extracorporeal shock-wave lithotripsy (ESWL) has been recognized in Japan[12, 13] since Sauerbruch reported this treatment in 1987.
