Hello, ashok.1224, I know that it is very hard when you have a one year old at home . From your decription , your wife has been experiencing pain for the past seven days. Eventhough she has a single stone , she can still have a full blown gallbladder inflammation . If it becomes an emergency situation when she develops severe pain, fever, chills, nausea, vomiting , ans yellow jaundice , that rquires immediate hospitalization and emergency surgery. At that time they may not be able to do the laparoscopic surgery .This type of surgery can be very safely done on an elective basis with in and out procedure, same day. The recovery is faster also. My personal preference would be not to wait till things get worse and turn into an emergency. I am sure the grandparents or other family members can help while she is recuperating. As I mention, she goes in the morning ,has her surgery and barring any unexpected complications, she should be back home the same evening. I hope this helps you to take appropriate action.
