RESUMEN
Pancreatic duct stone is a sequel of chronic pancreatitis and may be found in the main ducts,side branches or parenchyma.These stones obstruct the pancreatic ducts and produce ductal hypertension,which leads to pain,the cardinal feature of CP.Surgical operation has been the preferred treatment of pancreatic duct stones in many domestic and external pancreatic medical centers.Lithotomy by longitudinal pancreatic duct incision and Roux-en-Y anastomosis of pancreatic duct to jejunum is the main and effective surgical procedure,while micro-surgery was also rational for the treatment of pancreatic duct stones.However,further studies with a larger sample size and longer follow-up duration are needed to improve the surgical technique and verify our initial results.
RESUMEN
[Objective]To compare the immediate therapeutic effects of the treatment of gluteal muscle constracture(GMC)with arthroscopic release of contractured tissue and conventional surgery.To investigate the indications of arthroscopic surgery.[Method]Ninty-six limbs of 48 patients with traditional surgery and 84 limbs of 42 patients with arthroscopic surgery were analyzed in terms of operation time,length of the incision,postoperative pain,complications,the time of exercise,postoperative hospital stay and one-year recurrence rate.[Result]Arthroscopic surgery group had smaller incisions,earlier exercise,less postoperative pain and shorter hospital stay than conventional surgery group,but the two groups showed no significant difference in operative time,complications,effects of operation and one-year recurrence rate.[Conclusion]Arthroscopic release of contracture tissue is a safe,effective,economical and cosmetic way to treat the gluteal muscle contracture.This method is worthy of wide promotion.
