Preoperative CTLG visualized the correct number and site of SLNs in surrounding anatomy during routine computed tomography to evaluate distant metastases. Referring to CTLG, SLNs were identified using IGFI, resulting in successful SLN navigation and saving time and cost. This method appears clinically applicable as a less-invasive method for treating superficial esophageal cancer.
EGFR represents a predictor of postoperative recurrence and sensitivity to triple-drug combination therapy including a taxane. EGFR-positive patients may show improved prognosis with taxane combination chemotherapy and molecular targeted therapy for HER family members.
About 50% of patients who have a permanent stoma experience some degree of parastomal hernia formation. To prevent this complication, the extraperitoneal route is considered to be more effective than the transperitoneal route in the case of open colorectal surgery. This technique also has superiority in avoiding postoperative intestinal obstruction. Although laparoscopic surgery for rectal cancer has not been proved to be as safe as open surgery by a randomized-controlled trial, some studies have shown the equality of long-term results with laparoscopic low anterior resection and laparoscopic abdominoperineal resection. It is anticipated that cases of laparoscopic abdominoperineal resection will increase in the near future. However, a laparoscopic technique for creation of a permanent stoma has hardly been discussed. Most operative procedures for laparoscopic stoma creation have been performed with transperitoneal route, which may cause parastomal hernia and/or intestinal obstruction. This report describes a laparoscopic technique for permanent sigmoid stoma creation through the extraperitoneal approach.
Xanthogranulomatous changes in the pancreas are extremely rare. A 66-year-old man presented with a 2-year history of epigastralgia. Computed tomography scan revealed a 4-cm low-density area around the body of the pancreas. Magnetic resonance imaging demonstrated that the mass appeared hyperintense on a T2-weighted image and isointense on a T1-weighted image. Based on a diagnosis of invasive ductal carcinoma of the pancreas, distal pancreatectomy and splenectomy were performed. Sections examined from the mass showed an aggregation of many foamy histiocytes, lymphocytes, and plasma cells. The surrounding pancreatic tissue showed fibrosis and chronic inflammation. These findings suggested a xanthogranulomatous inflammation, and resulted in a diagnosis of xanthogranulomatous pancreatitis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
