To compare the clinical effects of different anti-reflux digestive tract reconstruction techniques after proximal gastrectomy.

Clinical data of 83 patients with gastric cancer who underwent proximal gastrectomy and underwent postoperative anti-reflux digestive reconstruction from January 2020 to December 2022 were retrospectively analyzed. According to the methods of anti-reflux digestive reconstruction, they were divided into Cheng group (receiving esophagogastric "Cheng Giraffe reconstruction", n=36 cases) and interposition jejunal group (receiving interposition jejunostomy, n=47 cases). SPSS 25.0 software was used to process the data. Perioperative indicators, gastrointestinal symptom Rating Scale (GSRS) score and nutritional status 6 months after surgery were expressed as () . Independent sample t test was used for comparison between groups. The long term complications were measured by χ² test. P < 0.05 was considered statistically significant.

The length of hospital stay in Cheng's group was shorter than that in interposition jejunum group, and the difference was statistically significant (P < 0.05). Six months after surgery, the increase of hemoglobin, albumin and body weight in Cheng's group was higher than that in interposition jejunum group, the differences were statistically significant (P < 0.05). There was no significant difference in the total incidence of long-term complications between the two groups (P > 0.05). Compared with pre-operation, GSRS scores in both groups decreased 6 months after surgery, and Cheng's group was significantly lower than interposition jejunum group, with statistical significance (P < 0.05).

Compared with interposition jejunostomy, the use of esophagogastric Giraffe reconstruction after proximal gastrectomy can significantly shorten postoperative hospital stay, improve nutritional status and alleviate gastrointestinal symptoms in patients with gastric cancer.
