Impact of Arteriosclerosis on Reconstruction-related Complications After Esophagectomy and Usefulness of Tailor-made Reconstruction Technique.

BACKGROUND/AIM: Anastomotic leakage is one of the most common and serious postoperative complications following esophagectomy. This study analyzed the effect of risk factors, such as the degree of arteriosclerosis, comorbidities, and patient characteristics on the incidence of reconstruction-related complications including anastomotic leakage. Furthermore, the usefulness of tailor-made reconstruction methods was clarified using wide gastric conduit.

PATIENTS AND METHODS

Patients who underwent esophagectomy with a gastric conduit for esophageal cancer between 2011 and 2018 were enrolled. In the initial group that underwent esophagectomy between August 2011 and February 2016, gastrointestinal reconstruction was performed using a narrow gastric conduit. In the latter group, reconstruction using subtotal gastric conduit was selected for high-risk patients between March 2016 and March 2018. Postoperative complications including reconstruction-related complications were assessed.

RESULTS

The occurrence of anastomotic leakage was significantly associated with the patient's risk in the initial group. The rates of anastomotic leakage and reconstruction-related complications were significantly lower in the latter group than in the initial group (3.2% vs. 23.0%, p=0.001; 27.0% vs. 44.3%, p=0.044). The incidence of all complications was significantly lower in the latter group than in the initial group (28.6% vs. 59.0%, p=0.001). The change in bodyweight loss one year after the operation was significantly lower in the latter group than in the initial group (p=0.042).

CONCLUSION

Tailor-made reconstruction using wide gastric conduit for high-risk cases of esophageal cancer could reduce the occurrence of anastomotic leakage and promote a better quality of life after surgery.
