Reconstruction methods after proximal gastrectomy for cancer

The study on gastrointestinal tract reconstruction after proximal gastrectomy (PG) for stomach cancer aimed to identify the most optimal way to restore the integrity of the gastrointestinal tract. The study involved a comparative analysis of 23 papers with a total of 1,517 cases of reconstructions after PG from four countries during the period 2010-2021. The five most commonly described types of reconstruction after PG were analyzed: jejunal interposition, esophagogastric anastomosis, ‘double tract' reconstruction, ‘double flap' reconstruction, and jejunal pouch interposition. The comparison criteria included the duration of surgeries, intraoperative blood loss, length of hospital stay, as well as postoperative complications such as anastomotic leakage, anastomotic stricture, reflux esophagitis, and residual food. The results of the study can provide valuable insights for surgeons in choosing the most optimal type of reconstruction after PG, thus reducing the risk of postoperative complications and improving the quality of life of patients with stomach cancer.
