Persistent dysphagia after laparoscopic fundoplication for gastro-esophageal reflux disease

DISEASES OF THE ESOPHAGUS, Issue 3 2008
U. Fumagalli
SUMMARY., Persistent postoperative dysphagia is a potentially severe complication of fundoplication for gastroesophageal reflux disease (GERD). The aim of this retrospective study was to analyze our experience of laparoscopic fundoplication for GERD in 276 consecutive patients, to determine the frequency of postoperative dysphagia and assess treatments and outcomes. There was no relation between preoperative dysphagia, present in 24 patients (8.7%), and postoperative DeMeester grade 2 or 3 dysphagia, present in 25 patients (9.1%). Ten (3.6%) patients had clinically significant postoperative dysphagia, eight (2.9%) underwent esophageal dilation, with symptom improvement in five. Four (1.4%) of our patients (two with failed dilation) and 11 patients receiving antireflux surgery elsewhere, underwent re-operation for persistent dysphagia 12 months (median) after the first operation. DeMeester grade 0 or 1 dysphagia was obtained in 10/13 evaluable patients. Our experience is fully consistent with that of the recent literature. Redo surgery is necessary in only a small fraction of operated patients with GERD with good probability of resolving the dysphagia. Best outcomes are obtained when an anatomical cause of the dysphagia is documented preoperatively. [source]

Single-session, graded esophageal dilation without fluoroscopy in outpatients with lower esophageal (Schatzki's) rings: A prospective, long-term follow-up study

Abstract Background:, Distal esophageal (Schatzki's) ring is a frequent cause of dysphagia. Bougienage is generally effective but relapses are common. The aim of this study was to evaluate the safety and long-term efficacy of single-session graded esophageal dilation with Savary dilators, without fluoroscopic guidance, in outpatients who presented with Schatzki's ring. Methods:, The study was performed on 44 consecutive patients with symptomatic Schatzki's ring, detected endoscopically and/or radiologically. Graded esophageal dilation was performed as an outpatient procedure in a single session with Savary dilators, without fluoroscopic guidance. After appropriate assessment with esophageal manometry and 24 h ambulatory pHmetry, patients with documented gastroesophageal reflux disease (GERD) were treated with omeprazole continuously. All results, including clinical follow up and technical aspects of bougienage, were recorded prospectively. The necessity for re-dilation after documentation of the ring with endoscopy and/or radiology was considered as a relapse of the ring. Results:, In four (9%) patients a second session was necessary to ensure complete symptom relief. Two (4.5%) patients developed post-dilation bacteremia and were managed with antibiotics as outpatients. Patients with (n = 14) or without (n = 30) GERD were comparable with respect to sex, age, body mass index, smoke and ethanol consumption, diameter of the esophageal lumen at the level of the ring, resting lower esophageal sphincter pressure, duration of dysphagia, need for taking antacids during the follow-up period, and duration of follow-up. There was no recurrence of the ring in patients with GERD during a mean follow-up period of 43.8 ± 9.3 months (range 27,62 months); however, in patients without GERD, during a mean follow-up period of 40.6 ± 12.2 months (range 10,58 months), 32% of patients relapsed after a mean 19.9 ± 10.6 months (P = 0.04). Conclusions:, Single-session graded esophageal dilation with large caliber Savary dilators without fluoroscopic guidance can be safely used for the symptomatic relief in patients with lower esophageal (Schatzki's) rings. GERD should be treated if present in order to prevent a symptomatic recurrence of the ring. [source]

Videofluoroscopic Swallow Studies in Unilateral Cricopharyngeal Dysfunction,

THE LARYNGOSCOPE, Issue 6 2003
Stacey L. Halum MD
Abstract Objectives/Hypothesis Although the cricopharyngeus muscle is a ring-like structure, unilateral cricopharyngeal dysfunction can produce significant dysphagia. This entity has not been well described in the literature. The aims of the study were to identify the characteristic findings on videofluoroscopic swallow studies in patients with dysphagia secondary to unilateral cricopharyngeal dysfunction, to note the associated vagal nerve injury, and to evaluate patient outcomes following ipsilateral cricopharyngeal myotomy. Study Design Retrospective clinical investigation. Methods The clinic charts, electromyographic tests, videostroboscopic examinations, and videofluoroscopic swallow studies were reviewed from a series of patients who presented to our institution from 1993 to 2001 with dysphagia and findings on videofluoroscopic swallow studies suggestive of unilateral cricopharyngeal dysfunction on posterior,anterior view. In patients treated with ipsilateral cricopharyngeal myotomy, postoperative findings on swallow studies and patient outcomes were also reviewed. Results Eighteen patients demonstrated findings characteristic of unilateral cricopharyngeal muscle dysfunction on videofluoroscopic swallow study. The common feature was a unilateral shelf-like barrier at the cricopharyngeus on the posterior,anterior view with pooling of liquid bolus in the ipsilateral pyriform sinus and episodic shunting to the contralateral side. Eight patients did not have evidence of cricopharyngeal dysfunction (ie, cricopharyngeal bar) on lateral films. Of the 18 patients, 14 had histories consistent with vagal injury secondary to trauma (n = 2), neoplastic involvement (n = 7), iatrogenic injury (n = 2), or central nervous system disease (n = 3). Results of videostroboscopic examinations demonstrated vocal fold motion impairment in 14 patients, and electromyographic test results confirmed unilateral vagal injuries in those who underwent electromyographic testing (n = 6). In the remaining 4 of 18 patients, videostroboscopic examinations demonstrated normal vocal fold abduction but impaired lengthening with a posterior glottic gap, and electromyographic test results (n = 4) indicated unilateral superior laryngeal nerve involvement. Of the 15 patients treated with ipsilateral cricopharyngeal myotomy, 1 patient required postoperative esophageal dilations for an esophageal stricture distal to the cricopharyngeus, whereas the remaining 14 patients had functional resolution of their dysphagia. Conclusion In patients presenting with dysphagia and evidence of unilateral vagal injury, careful assessment of posterior,anterior view on videofluoroscopic swallow study should be included to evaluate for unilateral cricopharyngeal dysfunction.
