Novel abdominal negative pressure lavage-drainage system for anastomotic leakage after R0 resection for gastric cancer

Figure 1 Schematic diagram of the novel abdominal negative pressure lavage-drainage system. During the entire study period, two #28 Penrose drains were routinely placed in the surgical resection bed in patients at the end of the procedure, one at the anastomotic site (tube A) and the other under the left diaphragm (tube B). In the ward, a #6 sputum suction tube (tube C) was placed next to the anastomotic stoma from the inside of tube A if anastomotic leakage occurred. ANPLDS: Abdominal negative pressure lavage-drainage system; AL: Anastomotic leakage.
