Hello - thanks for asking your question.
I have researched previously on SOD and post-cholecystectomy syndrome. I will reprint my research here.
The term postcholecystectomy syndrome (PCS) describes the presence of symptoms after cholecystectomy. These symptoms can represent either the continuation of symptoms thought to be caused by the gallbladder or the development of new symptoms normally attributed to the gallbladder. PCS also includes the development of symptoms caused by removal of the gallbladder.
Two types of problems may arise. The first problem is continuously increased bile flow into the upper GI tract, which may contribute to esophagitis and gastritis. The second consequence is related to the lower GI tract, where diarrhea and colicky lower abdominal pain may result. This article mainly addresses the general issues of PCS.
PCS reportedly affects about 10-15% of patients. A wide range of symptoms occurs. Symptoms are sometimes considered to be associated with the gallbladder. Colic is found in 93% of patients, pain in 76%, jaundice in 24%, and fever in 38%. The cause of PCS is identifiable in 95% of patients.
The workup for PCS is variable. An extensive study of the patient should be performed in an attempt to identify a specific cause for the symptoms and to exclude serious postcholecystectomy complications. Surgical reexploration should be considered a last resort.
The treatment depends on what is found on evaluation - it will vary depending on what the cause of your symptoms are.

I stress that this answer is not intended as and does not substitute for medical advice - please see your personal physician for further evaluation of your individual case.
Thanks,
