Patient factors influence surgical options in gastroparesis

Patient selection for the diverse surgical procedures for gastroparesis remains poorly defined. Our aim was to evaluate how patient factors have determined our surgical approach to gastroparesis.

95 patients undergoing 105 surgical procedures for gastroparesis were reviewed. Patient factors were compared across six surgical procedures: gastric neurostimulator, pyloroplasty, neurostimulator plus pyloroplasty, sleeve gastrectomy, gastric bypass and gastrectomy. Global symptom severity was determined preoperatively and at last follow up.

There were significant differences in etiology, BMI and gastroesophageal reflux across the various operations. Patients undergoing pyloroplasty and gastrectomy; were more likely to have a postsurgical etiology. (p < .05) Patients undergoing sleeve gastrectomy and gastric bypass were more likely to have BMI >35. ^{(p <.05)} Those undergoing sleeve gastrectomy were less likely to have gastroesophageal reflux preoperatively. ^{(p <.05)} There was no difference in preoperative clinical stage across the procedures.

Patient factors influence choice of procedure in the surgical treatment of gastroparesis. Etiology of gastroparesis, BMI >35 and gastroesophageal reflux are important determinants.
