摘要

Background

Gastric tube prolapse into the thoracic cavity in retrosternal route reconstruction during esophagectomy is known as intrathoracic herniation of the gastric tube (IHGT). However, few reports have determined whether a correlation exists between IHGT and postoperative complications. Moreover, the optimal procedure for avoiding IHGT remains unclear.

Methods

This retrospective study included 200 patients who had undergone subtotal esophagectomy and retrosternal gastric tube reconstruction at a single institution. The diagnosis of IHGT was defined as a gastric tube herniation length of ≥ 5 cm on plain chest radiography. The frequency of postoperative complications in patients with IHGT was measured to determine any correlation. The incidence of IHGT in a laparoscopic retrosternal route creation group was also measured and the efficacy of this procedure was investigated.

Results

The overall incidence of IHGT was 7.5%. The incidence of grade II or higher anastomotic leakage and atelectasis was significantly higher in the IHGT( +) (anastomotic leakage, 26.7% vs. 4.3%, P = 0.007; atelectasis, 40.0% vs. 13.5%, P = 0.016). In univariate analysis, IHGT( +) showed a significantly higher incidence of anastomotic leakage (OR 7.88, P = 0.007). In multivariate analysis, IHGT was an independent risk factor for atelectasis (OR 5.03, P = 0.005). Furthermore, the incidence of IHGT was significantly lower in the laparoscopic group (2.0% vs. 13.0%, P = 0.005).

Conclusion

Our findings show that IHGT may be correlated with grade II or higher anastomotic leakage and atelectasis. Laparoscopic retrosternal route creation may be effective in avoiding IHGT and contributes to a reduction in postoperative complications.
