吻合口漏是直肠癌保肛手术常见的严重并发症之一,也是术后死亡的重要因素.低位吻合口漏的发生率,各家报道不一。一般在5%～10%之间.大宗病例报道在14%左右.而在术后10～14d进行X线钡灌肠检查或碘水造影检查,认为只要有任何造影剂外渗均被认为是放射学的漏.Docherty发现放射学的漏远比临床发现的漏为高,可达51%～69%.而临床漏的发现主要是粪性引流物、粪漏、腹膜炎,在临床漏中死亡率可达1/3.
Anastomotic leakage is one of the common serious complications of sphincter preserving operation for rectal cancer, and it is also an important factor for postoperative death. The incidence of low anastomotic leakage is different from one report to another. Generally between 5% and 10%. Large cases are reported at about 14%. X-ray barium enema or iodine urography is performed 10 to 14 days after surgery. It is considered that any extravasation of contrast agent is considered as radiation. Leaching. Docherty found that the leakage of radiology is higher than the clinically discovered leakage, up to 51% to 69%. The clinical leakage is mainly found in fecal drainage, fecal leakage, peritonitis, mortality in clinical leakage Up to 1/3.
