ABSTRACT
Objective To investigate the diagnosis and treatment of rectal carcinoid. Methods Clinical data of 16 patients of rectal carcinoids in our hospital from January 2000 to December 2009 were analyzed retrospectively. Related literatures were reviewed. Results Among the patients included, 11 cases(68.8%)suffered from hypogastralgia, 3 cases(18.8%)bloody stool, 3 cases(18.8%)defecation number increase. All the patients underwent enteroscopy. The average size in diameter of all the tumors was 8.8 mm. 81.3% of the tumors ≤10 mm in diameter. The average distance from tumor to anus was 6.8 cm and 87.5% of the tumors ≤8 cm in distance, Only 25% of all the cases were diagnosed preoperatively, most cases were diagnosed as other diseases and definitely diagnosed by postoperative pathology. 14 cases underwent operation as radical resection of rectal carcinoma, and 2 cases endoscopic removal. There was no operative death and postoperative five-year survival rate is 69.2%. Conclusions Preoperative diagnosis rectal carcinoid is difficult.Misdiagnosis rate is high. The key point of improving diagnosis of this disease is annal digital examination. Enteroscopy and pathology, operation is the first choice to treat rectal carcinoid.
ABSTRACT
Objective To investigate the peripheral blood cytopenias in patients with portal hypertension complicated with splenomegaly. Methods The clinical data of 309 patients with portal hypertension who had been admitted to our department from January 1991 to December 2006 were retrospeetively analyzed. Results Of all patients, 278 showed peripheral blood cytopenia, ineluding 71 with paneytopenia, 48 with leukocyte and platelet decrease, 25 with erythroeyte and platelet decrease, 33 with leukocyte and erythroeyte decrease, 28 with platelet decrease, 26 with leukocyte decrease, and 47 with erythrocyte deerease. The number of blood cells increased significantly after splenectomy ( t=6.53, P<0.01). The whole blood cells of the remaining 31 patients without hematocytopenia were normal. Conclusions Patients with portal hypertension eomplieated with splenomegaly do not always accompany peripheral blood eytopenia. Peripheral blood cytopenia is one of the complications of splenomegaly, hut it dose not always appear. Splenectomy is effective in the treatment of hematocytopenia. The reason for some patients do not have peripheral blood cytopenia may be related to the slight pathological changes of spleen and severe hyperplasia of bone marrow.
ABSTRACT
Objective To investigate the therapeutic effects of latarjet nerve and pylous preserved pancreaticoduo-denectomy (LPPPD). Methods Clinical data and postoperative follow-up of Latarjet nerve and Pylous Preserved Pancreaticoduodenectomy since1996 of 32 cases were analyzed retrospectively, and 36 cases being carried out con-temporaneous Pylous Preserved Pancreaticeduodenectomy(PPPD) were compared with. Results The recovery time of postoperative gastrointestinal function recory time is five days of LPPPD group on average; but the time is eight days of PPPD group on average, and significantly slower than LPPPD group ( t = 3.01, P < 0.05 ) ; the occurrence of abdominal distenal, retention of gastric juice and enterogastric recurrent flow are significantly slower in LPPPD group than that in PPPD group( P < 0.05 ). Conclusion The postoperative gastrointestinal function recovered fas-ter, and the postoperative complications were less in LPPPD group than that in PPPD group.
ABSTRACT
Objective:To evaluate the effectiveness for vital pulpotomy in primary teeth with 4 kinds of pulp capping agents.Methods:CHI,CH,GA and FC were chosen as the pulp capping agents for vital pulpotomy in primary teeth and 3 year follow up observation was performed.The teeth in other side served as the controls.The root absorption was observed radiologically.Results:In the group of CHI,CH,GA and FC the clinical effective rate were 100%,87.5%,91.4% and 78.1%,the radiographical success rate were 97%,60%,74.3%and 56.2%,respectively.In the cases treated with CHI showed the highest success rate and significant difference was found among the four groups (P
