Partial bowels obstruction.
Thank you for the query.
Your main problem is caused by adhesions which have appeared after the surgery. Please note that every surgery causes adhesions in the abdominal cavity. Some adhesions does not give symptoms at all. But in some cases even a small adhesion can lead to partial bowels obstruction. Adhesion is like a stripe which can narrow the intestine.
Partial bowels obstruction give cramping, bloated abdomen, gas blockage, occasional diarrhea
. Symptoms can come and go. Every time you get an iv with smooth muscles relaxing medicines, the narrow place passes gas and stool so the symptoms go away.
Unfortunately, most likely you will need another surgery. Its because the comfort of living is very important. And it is really hard to live with symptoms you have.
That is why I suggest you to visit gastrologist. Abdominal CT with oral contrast (enteroclysis) should be done. Depending of the result, surgery should be considered.
Hope this will help. Feel free to ask further questions.
