Hybrid Natural Orifice Transluminal Endoscopic Surgery with Sentinel Lymph Node Navigation for Deep Early Gastric Cancer in the Fundic Region

For patients refusing surgical treatment for deep early gastric cancer, hybrid natural orifice transluminal endoscopic surgery with sentinel lymph node navigation is a potential treatment option, particularly when the anatomic location of the cancer has low probability of lymph node metastasis. We report a case of deep early gastric cancer of the fundus beyond the endoscopic submucosal dissection indication that was treated by hybrid natural orifice transluminal endoscopic surgery with sentinel lymph node navigation. In a conventional approach, a total gastrectomy would have been needed; however, the patient refused surgical intervention. In this case, since the patient showed no positivity of the sentinel lymph node on intraoperative navigation, laparoscopic basin lymph node dissection was not performed. Hybrid natural orifice transluminal endoscopic surgery might be considered for specific regions such as the safety zone where lymph node metastases are less likely to occur.

A Case of Sepsis Caused by Cellulitis in a Patient with Rheumatoid Arthritis after Tocilizumab Treatment

Tocilizumab, a humanized monoclonal antibody against the interleukin-6 receptor, is therapeutically effective in patients diagnosed with rheumatoid arthritis (RA) compared with placebo. However patients treated with tocilizumab are at increased risk of several adverse effects including anaphylaxis and serious infections that may lead to hospitalization or death. Therefore, the risks and benefits of treatment with tocilizumab should be considered carefully and close monitoring of patients for development of signs and symptoms of side effects is required during and after treatment. Here, we report on a rare case of anaphylaxis and severe sepsis caused by cellulitis in a patient with RA after tocilizumab treatment.
