Laparoscopic gastrectomy with regional lymph node dissection for upper gastric cancer

Abstract

Recently, a minimally invasive operation for gastric malignancies has been developed, and this laparoscopic operation is seen as a technique that will raise quality of life for patients. Previously, we reported this technique, as well as the results of a distal gastrectomy with regional lymph node dissection using hand-assisted laparoscopic surgery (HALS) for gastric cancer located in the middle or lower third of the stomach. This paper describes total or proximal gastrectomy with regional lymph node dissection by HALS on 28 cases of gastric cancer located in the upper portion of the stomach. After the mobilization of stomach and lymph node dissection via HALS, an anastomosis of the esophagus was performed intracorporeally with a conventional circular stapling device (PCEEA), whereas jejunojejunostomy and jejunogastrostomy were carried out extracorporeally with a conventional hand-sewn procedure through a HALS wound. The operation time and the amount of blood loss in all the patients were considered to be satisfactory, and the average number of dissected lymph nodes per patient was similar to that in open surgery. The patients had minimal morbidity and quick recovery after their operation. This technique was thought to be not only less invasive, but also similarly curative compared with open gastrectomy.
