title: The gastroplasty tube and its role in reflux control: an experimental and clinical study.
abstract: The gastroplasty tube has been used in the control of reflux since it was originally described by Collis in 1961. Several variations of the procedure have been reported indicating a low frequency of anatomic recurrence but a high frequency of reflux. Two forms of gastroplasty procedure are used: partial fundoplication in which gastric fundus incompletely wraps the gastroplasty and high pressure zone, and total fundoplication in which a circumferential wrap is constructed. The authors conducted a clinical review, using the patient's history, radiology and manometry, of 135 patients with partial fundoplication gastroplasty (PFG) and 250 patients with total fundoplication gastroplasty (TFG). In both groups the anatomic recurrence rate was low; however, with PFG the frequency of reflux was 44.6% and 25.7% of patients had notable symptoms. With TFG no patient had reflux. The response of the gastroplasty tube to meal-induced gastrin release and to neurogenic stimulation was tested. Basal tube pressure was low and showed no response to gastrin release and no augmented neurogenic response. It was concluded that the gastroplasty tube did not have intrinsic properties of value in controlling reflux and that reflux control depended upon the method of fundoplication. The role of the gastroplasty tube is in preventing anatomic recurrence.
