Double tract-like gastric tube reconstruction decreases the incidences of delayed gastric emptying and bile reflux after esophagectomy: results of a pilot study of an experimental technique.

PURPOSE: Esophagectomy with gastric tube reconstruction is often complicated postoperatively by duodenogastric reflux and/or delayed gastric emptying and the accompanying symptoms, leading to patients being dissatisfied with their quality of life (QOL). Medical interventions to relieve patients of their symptoms are rarely effective. We began, in 2018, performing double tract-like gastric tube reconstruction, and, in a pilot study, we compared postoperative QOL between patients in whom this experimental reconstruction was performed and those in whom conventional reconstruction was performed.

METHODS

Included in the study were 33 patients who underwent thoracoscopic McKeown esophagectomy with two- or three-field lymph node dissection for thoracic esophageal cancer between April 2015 and March 2020. A gastric tube about 4 cm in width was created in all patients, and in 14 of the patients (DT group), a double tract was appended by anastomosing the elevated jejunum to the anterior wall of the gastric tube, QOL was assessed 10-14 months later by means of the DAUGS-32 questionnaire, and bile reflux and the presence or absence of food residue were assessed by upper gastrointestinal endoscopy.

RESULTS

DAUGS-32 food passage dysfunction, nausea and vomiting, and reflux symptoms scores were significantly lower in the DT group than in the conventional reconstruction group. There was no significant between-group difference in the incidence of postoperative complications. No food residue was seen in DT patients' gastric tube, and no reflux esophagitis was observed.

CONCLUSION

Double tract-like gastric tube reconstruction shows promise as an effective means of improving patients' post-esophagectomy QOL.
