Hello - thanks for asking your question.
I agree with the comments below - you need to followup with your original surgeon as he or she would have the best vantage of what went wrong.
If you comment that your stomach bulges out, it is possible that there is an abdominal wall hernia. Acquired abdominal wall hernias primarily are those that develop from a previous surgical incision. They are the result of a variety of factors, including technical causes (eg, poor technique, inadequate suture material, insufficient tissue included in the suture, excessive tension), patient-based causes (eg, obesity, smoking, diabetes), and idiopathic causes (eg, wound infection, coughing).
Most abdominal wall hernias stemming from prior incisions should be surgically evaluated to prevent complications like incarceration and strangulation. Depending on the surgeon, prosthetic material such as a mesh may or may not be used. As I am not a surgeon, my insight is limited.
Regarding passing gas - again, this needs to be addressed with your original surgeon who did the procedure. For temporary relief, you may want to try some of the over-the-counter medications such as Gas-X and Beano.
Followup with your personal physician is essential.
