Background: Recently, gastric stapling with posterior truncal vagotomy has been performed by laparoscopic surgery, as an alternative to highly selective vagotomy (HSV) and the Taylor procedure for the treatment of chronic duodenal ulcer. Aim: To investigate, after a mean 5-year follow-up, the effect of the stapling-modified laparoscopic Taylor procedure, on gastric secretion, emptying and reflux as well as clinical parameters and recurrence rates in patients treated for duodenal ulcer. Methods: 16 patients, aged 38–66 years, were treated from January 1993 to January 1996 (median 60.5 months), by the laparoscopic stapling-modified Taylor procedure, using the Endo-GIA stapler device. Assessment of the results of gastric acid secretion, solid and liquid gastric emptying, enterogastric reflux, endoscopic findings and clinical parameters, using the Visick grading, was performed. Results: Endoscopy found healing ulcer in 15 patients. One patient showed signs of chronic ulcerative disease without gastritis or pyloric stenosis indicative of progressive ulcerative diathesis and was classified as Visick III. 14 patients were classified as Visick I and 1 as II. The enterogastric reflux index ranged from 0 to 26%, basal and peak acid output were 1.4 ± 0.6 and 11.7 ± 6.1 mmol H⁺/h, respectively. The half-emptying times of the solid and liquid meal were 82 ± 7 and 16 ± 6 min, respectively. These results are likely to be similar to those obtained from series of patients who underwent HSV or Taylor procedure and are closed to those from healthy controls. Conclusions: The laparoscopic modified Taylor procedure, using the Endo-GIA stapler device allows a more rapid, technically easier and radical performance of the operation with excellent long- term results and should be included in the armamentarium of the treatment of chronic duodenal ulcer.

Erythromycin has been found to be a gastrointestinal prokinetic agent while acute hyperglycemia has been associated with delayed gastric emptying in healthy controls and diabetics. The aim of this study was to investigate whether hyperglycemia, per se, alters gastric motility, during erythromycin-induced acceleration of gastric emptying of solids in patients with truncal vagotomy and pyloroplasty (TVP) and the role of vagus nerves. Eight TVP patients and six controls underwent scintigraphic measurement of gastric emptying of a solid meal, during placebo in normoglycemia (5-8.9 mmol/liter glucose) or 200 mg intravenous erythromycin lactobionate in normo- or hyperglycemia (16-19 mmol/liter glucose) induced by intravenous glucose infusion, on separate days in random order. In the TVP patients during normoglycemia, the erythromycin compared to placebo accelerated the meal gastric half-emptying time (T1/2), (37.12 +/- 6.87 vs 91.88 +/- 11.53, P < 0.001) and decreased the lag-phase duration (P < 0.001) and the percentage of meal retained in the stomach at 120 min (P < 0.001). Erythromycin in hyperglycemia compared to normoglycemia increased T1/2 (61.25 +/- 10.67 vs 37.12 +/- 6.87, P < 0.001), prolonged lag-phase duration (P < 0.001), and the percentage of isotope retained in the stomach at 120 min (P < 0.001). The T1/2, the lag phase duration, and the meal retained in the stomach at 120 min, after giving placebo was significantly increased, compared to erythromycin administration in hyperglycemia (P < 0.001). Significant differences among patients and controls were found during gastric emptying after giving placebo and after erythromycin in hyperglycemia (P = 0.04 and P = 0.007, respectively), while nonsignificant differences were found after giving erythromycin in normoglycemia. We conclude that the effect of erythromycin-induced acceleration on gastric emptying is related to the plasma glucose level. Hyperglycemia reduces the erythromycin-induced acceleration of gastric emptying of solids in both controls and TVP patients. A significant increase in the delay of gastric emptying was achieved in TVP patients compared to controls after giving erythromycin in hyperglycemia and after placebo. Despite the inhibitory effect of induced hyperglycemia on gastric emptying, erythromycin is still able to accelerate the emptying rate and could prove to be a useful prokinetic agent under hyperglycemic conditions. Hyperglycemia may indicate a cholinergic-antagonist pathway that delays the erythromycin-induced acceleration of gastric emptying of solids and is more evident in vagotomized patients than controls, who retain the functional integrity of the vagus nerves.
