Postoperative function following laparoscopic collis gastroplasty for shortened esophagus.
BACKGROUND
Collis gastroplasty is indicated when tension-free fundoplication is not possible. Few studies have described the physiological results of this procedure, and no studies have evaluated outcomes of the endoscopic approach.


OBJECTIVE
To assess the long-term outcomes of patients treated with laparoscopic Collis gastroplasty and fundoplication.


METHODS
Case series.


METHODS
Tertiary care teaching hospital and esophageal physiology laboratory.


METHODS
Fifteen consecutive patients with refractory esophageal shortening diagnosed at operation. Complicated gastroesophageal reflux disease or type III paraesophageal hernia (or both) was preoperatively diagnosed with esophagogastroduodenoscopy, 24-hour pH monitoring, esophageal motility, and barium esophagram. Fourteen (93%) of the 15 patients were available for long-term objective follow-up.


METHODS
Laparoscopic Collis gastroplasty with fundoplication and esophageal physiological testing.


METHODS
Preoperative and postoperative symptoms, operative times, and complications were prospectively recorded on standardized data forms. Late follow-up at 14 months included manometry, 24-hour pH monitoring, and esophagogastroduodenoscopy with endoscopic Congo red testing and biopsy.


RESULTS
Presenting symptoms included heartburn (13 patients [87%]), dysphagia (11 patients [73%]), regurgitation (7 patients [47%]), and chest pain (7 patients). An endoscopic Collis gastroplasty was performed, followed by fundoplication (12 Nissen and 3 Toupet). There were no conversions to celiotomy and no deaths. Long-term follow-up occurred at 14 months. Esophagogastroduodenoscopy revealed that all wraps were intact with no mediastinal herniations. Manometry demonstrated an intact distal high-pressure zone with a 93% increase in resting pressure over the preoperative values. Two (14%) of these patients reported heartburn, and 7 (50%) patients had abnormal results on postoperative 24-hour pH studies (mean DeMeester score, 100). Biopsy of the neoesophagus revealed gastric oxyntic mucosa in all patients. Endoscopic Congo red testing showed acid secretion in only those patients with abnormal DeMeester scores. Of these 7 patients, 5 (36%) had persistent esophagitis and 6 (43%) had manometric evidence of distal esophageal body aperistalsis that was not present preoperatively.


CONCLUSIONS
Collis gastroplasty allows a tension-free fundoplication to be performed to correct a shortened esophagus. It results in an effective antireflux mechanism but can be complicated by the presence of acid-secreting gastric mucosa proximal to the intact fundoplication and a loss of distal esophageal motility. These patients require close objective follow-up and maintenance acid-suppression therapy.
