Ans. is d i.e. Fallopian tube Laparoscopic visualization of the pelvis is the most accurate method of confirming diagnosis of an acute P1D. However, it is not practical to advise diagnostic laparoscopy to all patients of PID, Indications of Laparoscopy in Acute PID : - Patients not responding to therapy, in order to confirm the diagnosis. - To obtain cultures from cul-de-sac or fallopian tube. - To drain pus. if necessary. Thus, cultures can be obtained from both cul-de-sac and fallopian tube.

You can have your opinion.
