Background: Gastric conduit is most widely used method for esophageal reconstruction. Despite its popularity, certain complications, such as anastomotic leakage and strictures, remain to be resolved. In the present study, we reviewed the outcomes of narrow gastric conduit compared to wide gastric conduit reconstruction.
Methods: We retrospectively reviewed 493 patients with esophageal cancer who received esophagectomy with reconstruction in Taichung Veteran General Hospital, Taiwan between January 2010 and December 2019. We performed gastric conduit reconstruction with two different methods, narrow gastric conduit made of multistaples (more than four staples) and wide gastric conduit made of two or three staples. Among the 493 patients, 170 patients underwent wide gastric conduit formation and 323 patients underwent narrow gastric conduit. After propensity score matching, 140 patients from each group were matched by 1:1.
Results: The average anastomotic leakage rate is 80 of 493 (16.23%). The leakage rate, length of hospital stay, intensive care unit (ICU) admission, and ICU stay were significantly lower in the narrow gastric conduit group than in the wide gastric conduit group. The need for postoperation dilatation was significantly higher in wide gastric conduit group (19.41% vs 11.76%, p = 0.0217), and the time to first dilatation was similar in both groups ( p = 0.9808). Similar results were observed even after propensity score matching. In univariate analysis, the narrow gastric conduit, circular stapler, video-assisted thoracic surgery, and laparoscopic surgery were associated with a reduced risk of anastomotic leakage. However, these factors are not statistically significant in a multivariate logistic regression analysis.
Conclusion: The narrow gastric conduit is not inferior to the wide gastric conduit and can be considered an alternative option for gastric conduit preparation.
