Comprehensive swallowing exercises to treat complicated dysphagia caused by esophageal replacement with colon: A case report.

Introduction: Surgical procedures for colonic replacement of the esophagus are most commonly associated with anastomotic stricture which cause dysphagia. In this report, we describe a rare case of a patient who demonstrated dysphagia resulting from an anastomotic stricture following esophageal replacement with the colon. All the treatments to dilate the anastomotic stricture were ineffective. To investigate the new treatment strategy for a case with complicated dysphagia, clinical dysphagia evaluations, functional oral intake scale (FOIS), videofluoroscopic swallowing study as well as high-resolution manometry were used to evaluate the swallowing function of the patient before and after treatments.
Interventions: Comprehensive swallowing exercises included the protective airway maneuver, tongue pressure resistance feedback exercise, Masako Maneuver swallowing exercise, and the effortful swallowing exercise.
Outcomes: Comprehensive swallowing exercises showed good effect in the patient. The FOIS score increased from level 1 to level 7. The videofluoroscopy digital analysis showed that the pharynx constriction rate was 23% and 50%, before and after treatment, respectively. The data from the high-resolution manometry displayed that: the value of the velopharyngeal pressure peak was 82.8 mmHg before treatment and 156.9 mmHg after treatment; the velopharyngeal contraction duration time was 310 milliseconds before treatment and 525 milliseconds after treatment; the value of the hypopharynx pressure peak was 53.7 mmHg before treatment and 103.2 mmHg after treatment; and the hypopharynx contraction duration time was 390 milliseconds before treatment and 1030 milliseconds after treatment. The swallowing visualization illustrated that a bolus could normally pass through the anastomotic stoma, and the bolus leakage was no longer present. The patient was able to eat various consistencies of food independently, and we were able to remove the jejunum nutrient catheter before discharging the patient.
Conclusion: For patients with dysphagia caused by anastomotic stricture following esophageal replacement with colon, the swallowing function can be improved by enhancing the pharyngeal impetus when treatment using esophageal dilation is ineffective.
