Abdominal distension is related to ascites and intestinal adhesion after half a year after ovarian cancer surgery. 1. Ascites: As patients with ovarian cancer will have a large amount of ascites, which will affect the normal peristaltic function of intestines; meanwhile, due to the gradual increase of ascites, patients will suffer from abdominal distension, lower abdominal distension, poor appetite and other manifestations. 2. Intestinal adhesion: for those who have a history of surgical operation in abdominal cavity and pelvis, intestinal adhesion may occur, which may affect the smooth passage of gas and food in the intestinal tract, and then abdominal distension, constipation and other clinical manifestations may occur; if the abdominal distension continues to aggravate, it is necessary to be alert to the occurrence of intestinal obstruction. For patients who have been suffering from abdominal distension for half a year after ovarian cancer surgery, it is suggested that they should go to regular hospitals to improve CT, ultrasound and other related examinations, so as to clarify the cause of the disease and then actively treat it under the guidance of doctors.
