For how long does it take to heal from an omentectomy before you can return to work?

Depends on reason: Omentectomy is a procedure where the lining of the abdominal cavity, the omentum is removed. But this is usually done for a certain reason, in many cases associated with cancer debunking operations, such as for ovarian or gastric cancer. This is often a fairly large open operation, so healing is varied and dependent on what reason it was done for, if for cancer, what the extent of involvement is.
