Thank you for the opportunity to help you with your question!
Thoracic esophagus is not covered by visceral peritoneum.
a continuation of the parietal peritoneum reflected at various places over the viscera, forming a complete covering for the stomach, spleen, liver, intestines from the distal duodenum to the upper end of the rectum, uterus, and ovaries; it also partially covers some other abdominal organs. It holds the viscera in position by its folds, including the mesenteries; the omenta; and the ligaments of the liver, spleen, stomach, kidneys, bladder, and uterus.
Please let me know if you need any clarification. I'm always happy to answer your questions.
