A study of 362 consecutive laparoscopic Nissen fundoplications.

BACKGROUND

Open Nissen fundoplication has been shown to be a very effective operation in the treatment of intractable gastroesophageal reflux. Because of its technical rather than amputative nature, this procedure offers itself to a completely laparoscopic approach. Several studies have shown the feasibility; however, very few have dealt with the effectiveness of the laparoscopic approach.

METHODS

Results of laparoscopic Nissen fundoplications performed during a 6-year period were reviewed including duration of operation, number of hospital days, number of conversions to open procedures, complications, and symptoms. All 362 patients had evidence of gastroesophageal reflux disease documented by radiographic, endoscopic, or pH monitoring testing before the operation. Patients with dysphagia or odynophagia underwent manometric evaluation before operation. Postoperative evaluation included esophagography and endoscopy at 2 to 3 months with an esophagogram yearly thereafter. Follow-up time was 6 months to 6 years.

RESULTS

The mean time of operation decreased from 2.7 +/- 0.4 hours during the period from 1991 to 1994 to 1.8 +/- 0.3 hours from 1994 to 1997. During those same periods, the number of days of hospitalization decreased from 2.2 days to a mean of 1.5 days. Manometric studies done before the operation (n = 58) showed a pressure of 4 +/- 1.2 mm Hg compared with postoperative values (n = 39) of 14 +/- 1.8 mm Hg. The conversion rate was 0.8% (n = 3), and the complication rate of 1.9% (n = 7) included the 3 conversions, 2 pneumothoraces, 1 patient with postoperative bleeding, and 1 patient with a large abdominal wall hematoma. There were 5 failures of the procedure (1.2%). Thirteen patients (3.6%) described postoperative symptoms that persisted beyond 2 months, including bloating, flatulence, dysphagia, and diarrhea.

CONCLUSIONS

With strict selection criteria and increasing experience and standardization of technique, laparoscopic Nissen fundoplication can provide both safe and effective results for patients with chronic symptoms of gastroesophageal reflux disease.
