Abstract
Abstract
OBJECTIVES
Gastric emptying delay after oesophagectomy may occur in conduits exposed to pleural forces of respiration or anatomic obstruction. Remedial operations addressing both causes are rarely reported. The study aim was to categorize severe gastric conduit obstruction (GCO) and report the outcome of surgical revision.
METHODS
A single-institution, retrospective study of gastric conduit revision following oesophagectomy for oesophageal cancer investigated incidence, risk factors and categories of conduit obstruction. Evaluation consisted of contrast studies, computed tomogram and endoscopy. Interventions were categorized according to obstructive cause and included pyloroplasty, hiatal hernia reduction and thoraco-abdominal conduit repositioning.
RESULTS
Among 1246 oesophagectomies over a 17-year period, 14 patients (1.1%) required post-oesophagectomy relief of GCO. Two additional patients presented after oesophagectomy elsewhere. Before oesophagectomy, 18.8% (3/16) and 62.5% (10/16) of patients were on chronic opioid and psychotropic medications, respectively. Distinct anatomic features separated obstruction into 3 categories: pyloric in 31% (5/16), extrinsic in 12.5% (2/16) and combined in 56.3% (9/16). Operative revision led to complete symptom resolution in 50% (8/16) of patients and symptom improvement in 43.8% (7/16) of patients. One patient (1/16, 6.25%) in the combined obstruction group did not improve with surgical revision.
CONCLUSIONS
GCO after oesophagectomy rarely requires surgical revision. Potential association with medications affecting oesophageal and gastric motility requires further investigation. Classification of obstruction identifies a patient subset with lower success after surgical revision.
