We describe a rectus sheath hematoma 9 days after cesarean section at which
the visceral and parietal peritoneum was not closed. By the time of reoper
ation the parietal peritoneum had closed, the hematoma was limited to the a
bdominal wall, and there was no blood in the abdominal cavity. This suggest
s that leaving the peritoneum open is not a disadvantage if postoperative c
omplications develop. Unchecked bleeding into the abdominal cavity seems un
likely. The parietal peritoneum has closed 1 week after cesarean delivery.
