Abstract Background Intestinal duplication, a congenital malformation, is considered a rare condition, particularly in adults. Although it affects young children, a minority of patients remains asymptomatic until adulthood. Here, we describe a case of an intestinal duplication cyst that caused intus...

Abstract Background Although the first-line therapy for early-stage gastric mucosa-associated lymphoid tissue lymphoma is the eradication of Helicobacter pylori, the effect of eradication in Helicobacter pylori-negative cases is unclear. In this case report, we describe a surgical option for a case...

Abstract Background The strategy for treating obstructive colon cancers with metastatic lesions remains unclear. Herein, we report a case of laparoscopic ileo-transverse colon bypass (LITB) before preoperative chemotherapy for an obstructive right colon cancer. Case presentation A 59-year-old woman...

Primary colorectal choriocarcinoma is extremely rare with only 35 cases described in the literature during over 40 years. The neoplasm is characterized by biphasic tumor growth composed of adenocarcinomatous and choriocarcinomatous differentiation. Diagnostic elusiveness, aggressive nature and lack...

Abstract Background Anomalous bifurcation of the right superior pulmonary vein is an important anomaly that should be recognized not only in respiratory and cardiac surgeries, but also in esophageal surgery for the safe performance of surgery. We report a case in which thoracoscopic esophagectomy wa...

X-ray polarization is a unique new probe of the particle acceleration in astrophysical jets made possible through the Imaging X-ray Polarimetry Explorer. Here we report on the first dense X-ray polarization monitoring campaign on the blazar Mrk 421. Our observations were accompanied by an even dense...

GRB 221009A is the brightest gamma-ray burst (GRB) observed to date. Extensive observations of its afterglow emission across the electromagnetic spectrum were performed, providing the first strong evidence of a jet with a nontrivial angular structure in a long GRB. We carried out an extensive observ...

The distribution of angular correlations between prompt charm hadrons and primary charged particles in pp collisions is sensitive to the charm-quark hadronisation process. In this letter, charm-baryon correlations are measured for the first time by studying the azimuthal-angle difference between cha...
