Colorectal cancer complications

Perforation of the colon cancer
1. Pathological changes and clinical performance

(1) acute peritonitis-piercing: Its characteristics are a result of colon cancer and abdominal perforation of the same, the gap larger, a lot of logistics to the contents of the colon causing acute abdominal diffuse peritonitis, clinical, in patients with acute perforation of the former frequently have varying degrees Low of obstruction, abdominal pain, abdominal distention and stop defecation, such as the precursor symptoms of abdominal asymmetry that intestinal type, the entire abdominal tenderness, muscle tension.

(2) sub-acute abscess-piercing: pathology on the perforation often occurred in the primary tumor site, but no colonic obstruction there. Often due to the continuous growth of tumors, the Department of Nutrition obstacles Cancer Center, in necrosis, Po Kui, the same loss and abdominal cavity. Due to perforation of small tumor proximal lumen without obstruction, mesocaval pressure is not high, the colon into the abdominal cavity and less relief, the surrounding tissue adhesion formation of local parcels of abscess or inflammatory mass. Clinical patients early in the perforation of the acute abdomen often without clinical manifestations, such as abdominal abscess formation, there may be limitations in patients with abdominal pain, persistent high fever, elevated blood, abdominal tenderness obviously touched the masses.

(3) chronic perforation of the colon fistula: the invasive growth of colon cancer to surrounding tissue and adjacent organ involvement with the adhesion of the primary cancer tumor necrosis, shedding. When penetrating perforation adjacent organ involvement, the formation of various types of colon fistula, a common clinical organ fistula for colon ileum fistula, colon jejunum fistula, colon and duodenum fistula guitar gastrointestinal fistula.

2. Treatment

(1) the treatment of acute peritonitis perforation: perforation of the colon cancer caused by peritonitis, piercing a short time, in three to four hours within the short period of time before the active preparations for the operation, should seek to focus the tumor resection and perforation. Such as patients with critical condition, abdominal perforation after serious pollution or with shock and can not tolerate more surgery, will stage Ⅰ stoma, peritoneal drainage, Ⅱ period tumor resection anastomosis suitable.

(2) perforation abscess formation of colon cancer treatment: right colon and proximal transverse colon perforation caused by the abscess to Phase I tumor resection anastomosis is feasible, remote transverse colon and left colon perforation caused by the abscess should be preferred Hartman's surgery, If the patient re-poisoning symptoms. Abscess drainage and then to first stage Ⅱ tumor resection anastomosis suitable.

(3) of colon cancer, fistula treatment: This type of colon cancer because of the non-perforated acute clinical process, in general do not have to deal with emergency surgery, should be fully prepared before the case of elective surgery for stage Ⅰ radical surgery or cancer Resection.

(C) anorectal cancer is bleeding under one of the major causes gastrointestinal bleeding, according to the rate of bleeding and clinical divided into three types, acute bleeding, bleeding dominant and recessive bleeding. Anorectal cancer of the lower gastrointestinal bleeding caused by the treatment of two aspects, one for the control of bleeding, and the other for their own causes cancer treatment. Shall, in accordance with the hemorrhagic type, tumor patients and the general situation in the areas of integrated consider, as appropriate, individually or two at the same time take into account the implementation.
