Risk factors of anastomotic leakage after laparoscopic assisted Dixon / 中国现代普通外科进展

ABSTRACT

Objective:To observe the incidence and risk factors of anastomotic leakage after laparoscopic assisted Dixon.Methods:120 patients accepted laparoscopic Dixon operation in our hospital from March 2013 to March 2015 were selected as the observation object.By using the method of retrospective study,the postoperative incidence the anastomotic fistula were counted,and analyzed the risk factors for anastomotic fistula.Results:Among the 120 patients with postoperative anastomosis fistula,21 patients occurred anastomotic leakage,the anastomosis fistula incidence rate was 17.5％.Univariate analysis showed that the anastomosis fistula incidence rate of patients with more than or equal to 65 years of age,body mass index ＞ 23 kg/m2,diabetes mellitus,albumin is more than or equal to 35 g/L,preoperative radiotherapy,chemotherapy and anastomosis from the anal ＜ 7 cm were higher,the difference was statistically significant (P＜0.05).Logistic regression analysis showed that more than or equal to 65 years of age,diabetes mellitus,albumin is more than or equal to 35 g/L,anastomosis from the anal ＜7 cm were risk factors of anastomosis fistula in rectal cancer patients with Dixon operation (OR=4.356,5.238,3.562,4.415,P＜0.05).Conclusion:The factors of patients with laparoscopic Dixon operation after anastomosis fistula are age,diabetes,serum albumin levels and anastomotic distance from the anus.
