Operative and Long Term Oncological Outcomes After D2 Versus D1 Gastrectomy of Operable Gastric Cancer

This observational study included 80 consecutive patients presented by operable gastric cancer treated by D2 gastrectomy at Alexandria University hospital between January 2010 and January 2016, (Group I). Another 68 consecutive patients presented by operable gastric cancer treated by D1 gastrectomy earlier during the same period were included as a control (Group II). All patients had undergone preoperative gastroscopy and biopsy, chest and abdomen computed tomography (CT). All surgeries were performed by surgeons experienced in both D1 and D2 dissection and a standardized protocol for D1 and D2 gastrectomy was followed in all patients. The type of gastrectomy (distal or total) was done according to the site of the tumor; distal gastrectomy was done if there is a free safety margin of 4 cm beyond the proximal resection line otherwise total gastrectomy was done. Resection of the spleen and/or pancreatic tail were done if directly invaded by the primary tumor or metastatic LN. Patients with p T2 or greater, or with positive LN received adjuvant chemotherapy. Follow up was done as outpatient visits for average 5 years. Both groups were compared regarding postoperative morbidity and mortality, disease recurrence and survival rates.
