The experiment consists to work out the time optimum to yield a minimum scar formation. Methods By means of transmitting electronic microscope (TEM), computer assisted three-dimensional morphometry (CAM), and biochemical analysis to determine the extracellular collagen volume density (ECVD) and biochemical collagen content (BCC), to analyze the ultrastructure and components within scar tissues removed from the specimens in 3 groups of experimental animals were detailed. Results In the animals of simple choledoco-jejunostomy (CJ) group, active scar proliferation was seen in all specimens excised within one year after operation. In the stent group, decreasing collagen fibers arranged in orientation began to appear in the 6-month specimens and scar maturation existed in the 9- and 12-month specimens. In periodic tube withdrawal group, 3 months following tube ablation, scar proliferation recurred in the 6th month tube retaining animals, whereas scar maturation without recurrence happened in animals following 9 to 12 months tube retaining. Conclusion 9～12 months of tube stent is necessary for stable scar maturation.展开更多

Preoperative studies including abdominal ultrasonography and magnetic resonance imaging were performed, but they could not accurately determine the nature of the tumor. At laparotomy, a large cystic tumor of the small bowel mesentery was found. Histopathologic examination diagnosed the tumor as a cystic lymphangioma.Although lymphangiomas are rare, especially in the abdomen of adults, they may sometimes present as acute abdomen,causing complications that require emergent surgery.展开更多

Clinical data were reviewed retrospectively.Results Ten patients remained alive in the Group A. Among them, 9 survived without jaundice, the oldest one being 9-years old. One of the 9 patients had portal hypertension. The remaining one who survived with jaundice and portal hypertension was 8-years old at follow up. Ten patients in the Group B remained alive. Of them, 8 survived without jaundice and 2 with jaundice.Conclusions Two surgical procedures had similar effects in preventing reflux cholangitis, while spur valve has the benefit of quitting cutaneous enterostomy.展开更多
