Hello - thanks for asking your question.
Please understand my limitations over the internet as I have neither met nor examined you. This information is for patient education only. Please see your personal physician for further evaluation.
Studies show a success rate of GERD surgery based on symptom relief in pediatric patients ranges from 57-92%. The most common complications are breakdown of fundoplication, small bowel obstruction, gas-bloat syndrome, infection, atelectasis or pneumonia, perforation, persistent esophageal stricture, and esophageal obstruction.
In general, the Nissen fundoplication, which is a complete 360° wrap, best controls the symptoms of GERD but may lead to more episodes of dysphagia and gas bloat than a partial wrap. If feasible, you may want to re-evaluate the surgery. You would have to discuss this with your surgeon.
A diagnosis of functional dyspepsia may also be considered. Functional dyspepsia is not rigorously defined in children. In children mature enough to provide an accurate history, the criteria for diagnosis of dyspepsia are: 1) Persistent or recurrent pain or discomfort centered in the upper abdomen, and 2) No evidence (including an upper endoscopy) that organic disease is likely to explain the symptoms, and 3) No evidence that dyspepsia is exclusively relieved by defecation or associated with the onset of a change in stool frequency or stool form. Pain or discomfort in the upper abdomen has to be present at least 12 weeks, which need not be consecutive, within the preceding 12 months.
Studies show that children with functional abdominal pain have more abnormal electrical activity in the stomach with slower movement of stomach contents. Endoscopy, ultrasound, upper gastrointestinal x-rays with small bowel follow-through, and gastroduodenal manometry are the usual tests ordered for children to look for organic disease.
If all tests come back negative, then focus should made on symptomatic relief. You have already tried H2-blockers (pepcid) and nexium/prevacid. Use of antidepressants, prokinetic agents (i.e. reglan), and biofeedback have had varying success and may be attempted.
Followup with your personal physician is essential. If a referral has not already been made, I would suggest seeing a pediatric gastroenterologist.
