ABSTRACT
Objective To compare the effect of mini-incision cholecystectomy (MC) and laparoscopic cholecystectomy(LC). Methods Totally 168 patients with gallbladder disease were treated by cholecystectomy, they were divided into MC group (90 cases) and LC group(78 cases) using random digits table,and comparing the clinical effect between the two groups. Results The operating time was significantly shorter in MC group [(37.2 ± 12.3) win] than that in LC group [(51.6 ± 14.6) min](P＜0.05). The length of stay and postoperative recovery time were (1.7 ± 1.1), (15.9 ± 3.2) d in MC group,(1.8 ± 0.9), (14.8 ± 4.9) d in LC group, there was no significant difference between the two groups (P＞0.05). Body mass index had no influence to the operating time and postoperative recovery time. Conclusions With not complexity cholecystolithiasis, compared with LC, MC had shorter operating time, but no significant difference in postoperative recovery time. The MC procedure also seems to be suitable for the obese patients.
ABSTRACT
The distribution and morphology of 5-HT immunoreactive endocrine cells in the gastrointestinal tract of 5 adult rats were studied by the immunohistochemicael PAP method with nickel-intensified DAB on paraffin sections of intestine rolls. The density of 5-HT immunoreactive endocrine cells in the gastrointestinal tract of the rat is highest in the pylorus, duodenum and colon and moderate in the jejunum, ileum, caecum and rectum and lowest in the body of the stomach. The 5-HT immunoreactive endocrine cells are various in shape. Some of them have several processes extending between other epithelial cells. The basal portion of some endocrine cells have processes with 5-HT positive substance accumulating in their ends. The processes of the basal portion of some endocrine cells extend into lamina propria through the basal membrane. The 5-HT positive substance of many endocrine cells can be found to extend to luminal surface of the crypt or intestinal tract. These results indicate that the 5-HT immunoreactive endocrine cells can release 5-HT by both endocrine and exocrine ways.
