目的研究探讨负压吸引在直肠癌术后吻合口漏中的应用与疗效。方法应用负压吸引对15例直肠癌术后吻合口漏的患者进行治疗(A组),记录治疗后患者的体温、血象、住院天数以及腹腔引流液的量,同时与未行负压吸引治疗组9例(B组)比较并分析。结果A组与B组在住院日数、引流液的量上比较差异有统计学意义(P<0.05),A组患者临床恢复优于B组。结论负压吸引在一定程度上能够有效治疗直肠癌术后吻合口漏,降低二次手术率。 Objective To study the application and curative effect of negative pressure on anastomotic leakage after rectal cancer surgery. Methods Fifteen patients with anastomotic leakage after rectal cancer were treated with negative pressure (group A). ​​The body temperature, hemogram, length of hospital stay and peritoneal drainage volume were recorded. At the same time, Group 9 cases (group B) were compared and analyzed. Results There was significant difference between the days of hospitalization and drainage in group A and group B (P <0.05). The clinical recovery of group A was better than that in group B. Conclusions Negative pressure suction can effectively treat the postoperative anastomotic leakage and reduce the secondary operation rate of rectal cancer to a certain extent.
