If it appears for a short period of time, we should consider whether it is caused by a hernia or the accumulation of fecal masses and other factors. If it occurs for a long time, we should consider whether there is a tumor. Clinically common gynecological tumors, including tumors of fallopian tube, ovary, uterus or intestinal tract, are prone to hard pouch on the right side of the abdomen. The patient’s ultrasound, CT and colonoscopy must be combined with the patient’s clinical symptoms, such as the presence of pus-like stool or abnormal vaginal bleeding, abdominal distension, abdominal pain, ascites, etc., to make a corresponding assessment. Based on the examination and clinical symptoms, the patient’s diagnosis can be confirmed, and only after the diagnosis is confirmed can precise treatment be given. For example, for intestinal tumors, clinical diagnosis can be confirmed by colonoscopy. For gynecological tumors, clinical ultrasound or pathological biopsy can confirm the diagnosis. For some tumors with unclear diagnosis, open abdominal investigation can be performed clinically.
