Exploration and development of indocyanine green fluorescence applied in laparoscopic splenic hilum lymph node dissection for gastric cancer / 中华肿瘤杂志

With the continuous development of laparoscopic techniques and the concept of individualized treatment, laparoscopic surgery is also moving from "minimally invasive" to "minimally invasive plus precision" . Lymph node metastasis is one of the most important risk factors affecting the prognosis of gastric cancer (GC). Reasonable lymph node dissection has always been an important exploration direction in the field of GC surgery. In recent years, domestic and foreign studies have found that the new tracer, indocyanine green (ICG), can detect the lymphatic vasculature non-invasively, and more accurately display the perigastric lymph nodes, providing a new perspective in laparoscopic lymph node dissection for GC. Alternatively, since the application of ICG in laparoscopic gastrointestinal tumor surgery, especially in gastric cancer surgery is still in the early stage of exploration and experience accumulation, more high-level medical evidences are needed to evaluate its clinical value.

Primary Retroperitoneal Mucinous Cystadenocarcioma Involving the Splenic Hilum

Primary retroperitoneal mucinous cystadenocarcinoma is a rare tumor, and it is similar to its ovarian counterpart, but it is without any evidence of ovarian, pancreatic or any other extra-retroperitoneal origin. The histogenesis of this neoplasm remains uncertain. Mucinous or colemic metaplasia of the retroperitoneal mesothelium has recently been proposed as its origin. A 39-year-old woman was diagnosed with a 13-cm cystic lesion in the left retroperitoneum; this was mucinous cystadenocarcinoma and no primary tumor was identified. We report here on a primary retroperitoneal mucinous cystadenocarcinoma that involved the splenic hilum, and we include a review of literature.
