BACKGROUND/AIMS: To divide or not the short gastric vessels during Laparoscopic Fundoplication (LF) is still controversial. This retrospective study is based on short gastric vessels division (SGVsD), if necessary, during LF to construct a satisfactory loose wrap and to evaluate its effect upon the symptomatic and physiologic outcome in patients with proven GERD. METHODOLOGY: 150 patients (90 males, 60 females) with a mean age of 37 +/- 9 with typical symptoms of GERD, adequate motility study and positive 24-hour pH studies underwent LF; 100 (66.7%) were feasible after careful and complete fundal dissection without SGVsD while, 50 (33.3%) were not possible except with SGVsD. Outcome measures included assessment of the relief of the primary symptom responsible for surgery; repeated upper endoscopy and barium study. Postoperative 24-hour esophageal pH and LES manometry were performed in 110 patients. RESULTS: The mean operative time was prolonged with short gastric division (130 +/- 60 vs. 90 +/- 40 minutes). At a mean period of follow-up of 35 +/- 12 months, relief of the primary symptom responsible for surgery was achieved in 92.2% of patients with division and 87.5% of patients without. Recurrent attacks of abdominal distension were documented in 2 patients (5.6%) with division and 12 patients (16%) without division. Occasional dysphagia not present before surgery occurred in 27 patients at 3 months; 11 (31.4%) with division and 16 (21.3%) without, and decreased to 11 patients by 12 months after surgery; 2 (5.7%) with division and 9 (12%) without; only one case of those without division required 5 sets of endoscopic dilatation. Endoscopic esophagitis healed in all patients with division and 71 of 75 patients (94.7%) without. LES pressures had returned to normal in all patients except one case without division (1.3%) with a higher mean pressure among those without division (22.3 mmHg vs. 18.5 mmHg) and a better relaxation with division (89.9% vs. 80.5%). 24-hour esophageal acid exposure had returned to normal in 33 of 35 patients (94.3%) with division and 66 of 75 patients (88%) without. CONCLUSIONS: Construction of a satisfactory loose Nissen Fundoplication was feasible in two thirds of patients without SGVsD. Despite prolongation of the operative time, SGVsD provides a better symptomatic and physiologic outcome.
