1.1 Observation and determination of the activity of the cecum.In the early 1980’s, the surgeons at the Nanchong Municipal Central Hospital of Sichuan Province occasionally found that the cecum and appendix were located in the patient’s left lower abdomen when they performed sigmoidoscopy or operation on the patient’s left lower abdomen. The conventional appendectomy was performed by pulling the cecum and appendix out of the abdomen so as to remove the diseased appendix and to embed the residual end of the appendix.In the 1990’s, with the wide spread use of the peritoneoscope, these surgeons began to explore and determine the activity of the cecum.[2, 3] They read in Normal Human Anatomy (1961 ed., p.140) that the cecum is about 6-8 cm in length and is mostly covered with the peritoneum; therefore, it is capable of movements. Based on the anatomical determination and thousands of operations, these surgeons found that the activity of the cecum in the adults was in the range of 10-12 cm;[3] and the activity in the children was more than that range. ......
