Pneumoperitoneum Due to Spontaneous Uterine Perforation Caused by Pyometra – A Rare Finding and a Diagnostic Challenge

Abstract

Background: Spontaneous perforation of uterus resulting in generalized peritonitis in postmenopausal women is a very rare entity usually caused by pyometra and is associated with high morbidity and mortality. The clinical picture of uterine perforation secondary to pyometra are similar to hollow viscus perforation which makes preoperative diagnosis difficult. A correct and definitive diagnosis can be made with laparotomy or laparoscopy. Case: We report a case of 64-years-old female patient who presented with pain abdomen and distension and inability to pass flatus/motion with signs suggestive of acute generalised peritonitis and genital prolapse with pneumoperitoneum underwent Total Abdominal Hysterectomy with bilateral salpingo-oophorectomy. Results: Despite the surgical intervention, Total Abdominal Hysterectomy with bilateral salpingo-oophorectomy and use of several antibiotics, this patient did not improve and died post-operatively. Conclusions: This case report aim for awareness of the many etiologies for peritonitis is of great importance and to alert the surgeons to the possibility that uterine perforation secondary to pyometra also shows air under diaphragm apart from hollow viscus perforation. Correct diagnosis and proper treatment are essential for survival of patients.
