Safety and efficacy of double-tract reconstruction with remnant stomach conservation in esophagectomy for patients with a history of distal gastrectomy.

BACKGROUND

Total gastrectomy with jejunum or colon reconstruction after esophagectomy is commonly performed in patients with esophageal cancer who have a history of distal gastrectomy. In this study, we examined the safety and effectiveness of double-tract reconstruction (DTR) with preservation of the remnant stomach for said patient population.

METHODS

Twenty-seven esophageal cancer patients with a history of distal gastrectomy who underwent transthoracic esophagectomy between 2010 and 2020 in our institution were retrospectively analyzed; 15 of these patients underwent DTR, whereas 12 underwent completion gastrectomy with jejunal Roux-en-Y reconstruction (RYR). Short-term outcomes, postoperative nutritional indexes, and ghrelin levels were evaluated. Moreover, abdominal lymph-node metastasis and recurrence, which were removed by total residual gastrectomy, were examined to determine the oncological validity of residual stomach preservation.

RESULTS

There was no metastasis and recurrence in abdominal lymph nodes, such as #4sa or #11d, which were removed by total residual gastrectomy. Total operation time did not differ between the groups (P = 0.4247). The blood loss for the DTR group was 495 ± 446 mL, whereas that for the RYR group was 844 ± 575 mL (P = 0.0168). Clavien-Dindo grade III or higher complications were not significantly different between the groups (P = 0.7063). The rates of serum total protein values at 6 months in the DTR and RYR groups were 112% ± 12.2% and 102.6% ± 10.7% (P = 0.0403), respectively. The prognostic nutritional indexes at 6 months in the DTR and RYR groups were 108.6% ± 14.5% and 83.2% ± 42.6% (P = 0.0376), respectively.

CONCLUSIONS

DTR in esophagectomy is safe and effective for patients with a history of distal gastrectomy.
