Abstract
Background
In accordance with an increase of proximal gastric cancer, proximal gastrectomy came to be widely performed. Several types of reconstructive procedures after proximal gastrectomy have been developed and it is still controversial which procedure has the advantages in preservation of postoperative gastric stump function and nutritional status after proximal gastrectomy. In this study, we retrospectively analyzed reconstructive procedures in our consecutive case series for proximal gastrectomy, with particular focus on postoperative body weight maintenance, nutritional status, and gastric remnant functional preservation.
Methods
We enrolled 69 patients who received proximal gastrectomy for gastric cancer in our institute from 2005 to 2020. Short-term complications, preservation of gastric remnant functions, nutritional status, and post-operative weight changes were compared.
Results
After proximal gastrectomy, the numbers of cases receiving Direct Esophago-Gastrostomy, Jejunal Interposition, Double Tract Reconstruction, and Double Flap Technique were 9, 10, 14, and 36, respectively. Double Flap Technique cases suffered no reflux esophagitis after surgery. Prevalence of gastric residual at 12-month after surgery of Double Flap Technique was the lowest. Double Flap Technique group has better tendency in post-operative changes of serum albumin ratios. Furthermore, post-operative body weight changes ratio of Double Flap Technique was the smallest and significantly better than Double Tract at all the time points.
Conclusions
Double Flap Technique after proximal gastrectomy was considered as the most effective reconstruction which can maintain body weight, cause less reflux esophagitis and gastric residual.
