Background: Laparoscopic proximal gastrectomy (LPG) with double-tract reconstruction (DTR) is performed as a function-preserving surgery for patients with adenocarcinoma of esophagogastric junction. However, whether LPG with DTR has postoperative advantages over laparoscopic total gastrectomy (LTG) is debatable. To evaluate benefits of LPG with DTR, we compared short-term surgical outcomes between LPG with DTR and LTG for adenocarcinoma of esophagogastric junction (AEG).
Methods: Twelve patients who underwent LPG with DTR for AEG between February 2016 and August 2017 were included. Twenty-four patients who underwent LTG in the same period were matched to LPG with DTR cases for demographics, comorbidities, tumor characteristics, and tumor node metastasis stage. Short-term surgical outcomes were compared between the two groups.
Results: Demographics of the LPG with DTR group and LTG group were comparable. The number of harvested lymph nodes in the LPG with DTR group was less than that in the LTG group, and the amount of estimated blood loss, the operative time, the days of gas-passing, start of diet, postoperative hospital stay were not significantly different between the groups. Furthermore, the postoperative reflux symptom in the LPG with DTR group was not significantly different with that in the LTG group. However, the increasing percentages of the serum albumin, total protein, and hemoglobin levels in the LPG with DTR group were significantly higher than those in the LTG group.
Conclusions: This study reveals that LPG with DTR may be a valuable procedure for the treatment of AEG because it has the advantages over LTG in terms of postoperative serum albumin, total protein, and hemoglobin.
