4) Methods Divided 200 patients who had accepted gynecological peritoneoscopy into the observation group (100 cases) and the control group (100 cases) randomly.

5) Objective To investigate the value of transgastric NOTES peritoneoscopy in the diagnosis of patients with tuberculous peritonitis.

6) Conclusion Transgastric NOTES peritoneoscopy with biopsy is the crux of the diagnosis of tuberculous peritonitis.

7) Objective : To investigate the feasibility and safety of peritoneoscopy in treatment of ectopic pregnancy.

8) Limitations: Small number of subjects, animal model, no randomization. Gastrotomy trauma during short peritoneoscopy may not be applicable to longer procedures.
