The recent increase in the incidence of sexually transmitted disease and the recognition of Chlamydia trachomatis as a causative organism in both pelvic inflammatory disease （PID） and extra pelvic manifestation of PID have brought about the renewed interest in perihepatitis. This is likely to ensure that the clinical features of perihepatitis will now become widely recognised. This paper examines the evolution, clinical features, diagnosis and management of this interesting syndrome and emphasises the need to explore the upper abdomen during laparoscopic gynaecological surgery.展开更多
