Hi welcome to Health care magic forum.
Thanks for asking a question to H.C.M.Forum.
You had surgery on umblical hernia
with seven incisions
Hernia is a condition where the intestines,or mesentry protrudes into the wall structures, or internal structures. They can protrude in one direction or in more directions. Into the same passage or different.
Depending upon the internal structures incisions are planed and follow the procedure. If single structure protrudes into single passage single incision may be sufficient.
I hope i have replied to your satisfaction.
