Preliminary Efficacy Analysis of "C" Single Flap Plasty Reconstruction After Laparoscopic Proximal Gastrectomy

The incidence of proximal gastric cancer has increased significantly in recent years. This may be due to weight gain, alcohol consumption, gastroesophageal reflux disease (GERD), and precancerous lesions. With a deeper understanding of the pattern of lymph node metastasis and the emergence of anti-reflux procedures, proximal gastrectomy has gradually received clinical attention. For early-stage upper gastric cancer and esophagogastric combination cancer cases that are expected to have a good prognosis, the ideal surgical procedure should be to preserve the distal stomach to improve the quality of life and to choose a reasonable digestive tract reconstruction method to prevent reflux. The anti-reflux effect of various proximal gastrectomy digestive tract reconstruction methods and the advantages and disadvantages of various surgical procedures are controversial, and the recognized ideal reconstruction method has not yet been established. Therefore, we propose a reconstruction called the "C" Single Flap Plasty Reconstruction. This study aimed to investigate the efficacy and safety of proximal gastrectomy combined with "C" Single Flap Plasty Reconstruction in the treatment of gastric cancer.

Preliminary Efficacy Analysis of 'λ+α' Double-Tract Reconstruction After Laparoscopic Proximal Gastrectomy

The incidence of proximal gastric cancer has increased significantly in recent years. This may be due to weight gain, alcohol consumption, gastroesophageal reflux disease (GERD), and precancerous lesions. With a deeper understanding of the pattern of lymph node metastasis and the emergence of anti-reflux procedures, proximal gastrectomy has gradually received clinical attention. For early-stage upper gastric cancer and esophagogastric combination cancer cases that are expected to have a good prognosis, the ideal surgical procedure should be to preserve the distal stomach to improve the quality of life and to choose a reasonable digestive tract reconstruction method to prevent reflux. The anti-reflux effect of various proximal gastrectomy digestive tract reconstruction methods and the advantages and disadvantages of various surgical procedures are controversial, and the recognized ideal reconstruction method has not yet been established. Therefore, based on the stomach's anatomical features and the intercalated jejunum's anti-reflux mechanism, we propose a true dual-channel anastomosis for GI reconstruction, i.e., the "λ+α dual-channel anastomosis". This study aimed to investigate the efficacy and safety of proximal gastrectomy combined with "λ+α double-channel anastomosis" in the treatment of early gastric cancer.

Protocol for Comparing the Efficacy of Three Reconstruction Methods of the Digestive Tract After Proximal Gastrectomy

The efficacy of three different reconstruction methods after proximal gastrectomy will be investigated in this study through a prospective, multicenter, randomized controlled trial.
