Peritonitis is inflammation of the peritoneum that can arise from a number of complications affecting the lining of the abdominal wall and organs. Acute abdomen and peritonitis is a rare complication in a previously healthy woman following a seemingly uncomplicated normal full-term vaginal delivery. We report such a case in a 20-year-old gravida 2 para 2 (G2P2) woman of Guatemalan descent, who presented nine days postpartum following an uncomplicated delivery, to the emergency room with acute abdomen and associated systemic inflammatory reaction. Interventional radiology paracentesis was performed, yielding a milky, purulent peritoneal fluid with no visible organisms and negative cultures. Antibiotics and paracentesis were insufficient in managing her condition, which continued to worsen over the course of several days. Given her continued deterioration despite clinical intervention, she underwent an exploratory laparotomy and peritoneal lavage along with continued broad-spectrum antibiotics. Cultures continued to be negative but operative findings included diffuse fibrinous peritonitis with no obvious abscess or perforated abdominal viscus. Following surgical laparotomy, she recovered fully without any complications. We review the available literature regarding peritonitis, discuss its management, and speculate as to its cause in this case.
