ABSTRACT
In this paper,the feasibility and clinical significance of left hemicolectomy colocolostomy in treating the obstruction of the left colonic cancer were discussed.Preoperative preparation,intraoperative and postoperative treatments in 12 patients with the obstruction of the left colonic cancer who received left hemicolectomy colocolostomy were studied retrospectively.Radical resection was performed in all 12 patients.There was only 1 case of incision infection.No fistula of the anastomotic stoma was seen.From the results,left hemicolectomy colocolostomy was feasible in those with permitted situation,enough blood supply of colon without obvious colonic swelling and inflammation.The fistula of the anastomotic stoma was avoidable when the ways of preoperative preparation,intraoperative and postoperative treatments were emphasized.For reducing the economic burden of the patients,duration of hospitalization,avoiding suffering operation twice,especially improving the prognosis,it may be the best choice to resect the left colonic cancer in I stage.
ABSTRACT
To explore the relationship of expression of metastasis associated protein-CD 44 V 6 and proliferating cell nuclear antigen(PCNA) to lymph node metastasis in colorectal carcinoma,randomly selected patients with colorectal carcinoma who underwent coloproctectomy plus D 2～D 3 lymph node dissection were studied.The 104 patients were divided into:A group (n=48) without lymph node metastasis and B group(n=56) with metastasis.The expressions of CD 44 V 6 and PCNA were assayed by immunohistochemical technique.The results indicated that the 56 cases(75%) of B group were positive for expressions of CD 44 V 6 and PCNA,there was obvious correlation between both the expressions and lymph node metastasis(P
