Persistent dysphagia
Early temporary dysphagia must be differentiated from swelling in the wake of the procedure, which resolves spontaneously after a few weeks, and from persistent dysphagia.
Origins:
- Incorrect wrap position
- Wrap too tight or too long
- Propulsive esophageal disorder and dysregulation of the peristaltic wave in swallowing
Treatment:
- Bougienage (4 weeks after surgery the earliest)
- In confirmed stenosis with unsuccessful bougienage: Revision surgery
- After partial wrapping the rate of dysphagia is lower. 360° wraps should be avoided in propulsive esophageal disorders and dysregulation of the peristaltic wave in swallowing.
Denervation syndrome
Origin:
- Lesion of vagal innervation
Outcome:
- Delayed gastric emptying
- Bloating
- Diarrhea
Treatment:
- Medication (e.g. prokinetics)
- In some case pyloroplasty
Insufficient or ruptured wrap
Origins:
- Wrap too floppy or complete failure (e.g., fundus wrap fixated with absorbable sutures)
Outcome:
- Persistent postoperative reflux
Treatment:
- Revision surgery/de novo wrapping; if initial procedure was minimally invasive revision may also be performed laparoscopically
Telescope phenomenon
Origin:
- Insufficient fixation of fundus to stomach and esophagus results in wrap flipping and superior migration of the cardia, where the wrap now encircles the body of the stomach.
Outcome:
- Reflux from the newly formed fundus pouch combined with dysphagia due to fundus constriction by the wrap.
Treatment:
- Revision surgery/de novo wrapping; also possible laparoscopically
Gas-bloat syndrome
In the literature the term “gas bloating” describes a number of symptoms following fundoplication which supposedly arise from the gas induced distension of the stomach accompanied by inability to eructate. This includes:
- Epigastric complaints
- Bloating
- Pain in the back, chest and shoulders
- Inability to eructate
- Tympanitis
Often GERD patients already complain of gas-bloat syndrome before surgery, which is caused by frequent swallowing of saliva because patients are attempting to lessen their acid induced GERD complaints. Since 10 mL - 20 mL are swallowed each time when swallowing, to a certain extent the patients necessarily indulge in aerophagia which they often maintain after surgery.
Avoiding heavy meals and carbonated beverages is helpful, and bougienage may be an option. Revision surgery for gas-bloat syndrome should only be considered when suffering is truly severe.
It appears that gas-bloat syndrome is less likely in partial fundoplications.
