Objective: To demonstrate the effectiveness and safety of intraluminal endoscopic treatment of patients with adenomas of the major duodenal papilla and familial adenomatous polyposis.
Material And Methods: Over the past 4 years, 13 patients with adenomas of the major duodenal papilla and familial adenomatous polyposis underwent surgery in our hospital. Of these, 7 patients had exclusively extrapapillary adenomas without signs of spread to the ducts.

Background: Cancer of unknown primary (CUP) is a challenging malignancy characterized by metastatic tumors with an unidentified primary site, even after extensive pathological and radiographic evaluation. Recent advancements in gene expression profiling and comprehensive genomic profiling (CGP) using next-generation sequencing (NGS) have enabled the identification of potential tissue origins, thereby facilitating personalized treatment strategies. Although most cases of CUP present as adenocarcinomas or poorly differentiated tumors, the treatment remains largely empirical, with limited success from molecularly tailored therapies.

The confluence diseases of pancreaticobiliary ducts are important causes of benign and malignant diseases such as inflammation, stones, and tumors of the biliary and pancreatic systems. Endoscopic retrograde cholangiopancreatography (ERCP) has played an important role in the diagnosis and treatment of the confluence diseases of pancreaticobiliary ducts and the biliary and pancreatic systems diseases. However, excessive damage to the sphincter of Oddi (SO) can break the biliary tightness, leading to complications such as reflux cholangitis, stones, and tumors.

Background/aim: Endoscopic submucosal dissection (ESD) can be performed to treat laterally spreading duodenal papillary tumors (LSPTs). However, no studies have been conducted on the outcomes of ESDs for LSPTs.
Methods: We retrospectively compared 47 patients who underwent endoscopic papillectomies (EPs) for papillary tumors (PTs) between June 2007 and July 2023 (EP group) and eight patients who underwent ESDs for LSPTs between February 2022 and July 2023 (ESD group).

Background: Research on cancer in wild animals provides important insights into the mechanisms of carcinogenesis. Histiocytic sarcomas comprise a rare malignant macrophage-dendritic cell lineage neoplasm in wildlife. This study reports a case of histiocytic sarcoma in the small intestine of a collared peccary (Pecari tajacu), describing its clinical, anatomopathological, and immunohistochemical aspects.
