Laparoscopic Gastrectomy with D2 Lymphadenectomy for pT1a Adenocarcinoma: Case Report and Literature Review

Abstract Gastric cancer is one of the most common malignancies, associated with a high mortality and morbidity rate, especially in the elderly, the fourth leading cause of cancer mortality in Europe. Although the rate of diagnosis has declined in recent years, the prognosis of the disease and the mortality rate is still quite high. Laparoscopic surgery, accompanied by lymphadenectomy, is a curative method of treatment, used more and more frequently, especially in Eastern countries, both in the incipient disease and in advanced stages of the disease, which has many advantages over classical surgery. We report the case of an 86-year-old man, who presented for marked physical asthenia, weight loss and severe anemia, in whom we performed laparoscopic distal radical gastrectomy with D2 lymphadenectomy and Roux-en-Y reconstruction. Histopathological examination established the diagnosis of low-grade / well-differentiated tubular adenocarcinoma G1 (WHO) / intestinal carcinoma (Lauren), with invasion in the lamina propria, developed on an intestinal-type adenoma. 21 lymph nodes were taken without tumor invasion. This case highlights the complexity of laparoscopic intervention, with the proven advantages for the patient, like reduced surgical trauma and pain, with the decrease of postoperative complications, but also the difficulty of the surgical technique which requires advanced laparoscopic skills. Thus, in addition to its proven efficacy in cases of early gastric cancer, the technique can be extended to advanced malignancies, without affecting the oncological safety limit.
