Management of scope-induced type I duodenal perforations: Over-the-scope clip versus surgery.

Indian J Gastroenterol 2021 May 11. Epub 2021 May 11.

Department of Gastroenterology, G B Pant Institute of Postgraduate Medical Education and Research, 1, J L N Marg, New Delhi, 110 002, India.

Background: Scope-induced duodenal perforation is a life-threatening complication and surgery remains the standard of care. With the advent of over-the-scope clip (OTSC), scope-induced perforations are increasingly managed conservatively, though there is no study comparing this form of non-surgical treatment with surgery. We aimed to compare OTSC and surgery in the management of scope-induced perforation of the duodenum. Read More

Minimally Invasive Versus Open Pancreatectomy for Right-Sided and Left-Sided G1/G2 Nonfunctioning Pancreatic Neuroendocrine Tumors: A Multicenter Matched Analysis with an Inverse Probability of Treatment-Weighting Method.

Ann Surg Oncol 2021 May 9. Epub 2021 May 9.

Department of Surgery, Seoul National University Bundang Hospital, Seongnam-si, Gyeonggi-do, Korea.

This study aimed to compare the surgical outcomes of MIS and open surgery (OS) for right- or left-sided NF-PNETs.

Methods: The study collected data on patients who underwent surgical resection (pancreatoduodenectomy, distal/total/central pancreatectomy, duodenum-preserving pancreas head resection, or enucleation) of a localized NF-PNET between January 2000 and July 2017 at 14 institutions. Read More

Cureus 2021 Apr 6;13(4):e14323. Epub 2021 Apr 6.

Internal Medicine, University of California, Riverside School of Medicine, Riverside, USA.

Periampullary carcinoma is a broad term used to define the group of carcinomas arising from the head of the pancreas, the distal common bile duct, and the duodenum. It is clinically important to differentiate ampullary from periampullary carcinoma as this can affect resectability and prognosis. Atypical left-sided chest pain is an atypical presentation of periampullary duodenal adenocarcinoma. Read More

Biol Trace Elem Res 2021 May 5. Epub 2021 May 5.

Centre for Nutrition and Food Sciences, Queensland Alliance for Agriculture and Food Innovation, The University of Queensland, Brisbane, QLD, 4072, Australia.

This experiment was conducted to investigate the effect of the supplementation of hot-melt extrusion (HME) processed zinc sulfate (ZnSO) on the growth performance, antioxidative activity, pancreatic digestive enzyme, small intestinal morphology, nutrient digestibility, and Zn content in broilers. The chicks were allocated to three treatments, each of which had five replicates of 15 chicks per replicate. The broiler chickens were assigned to three dietary treatments: the control (without supplemental Zn), IN-Zn (ZnSO, 80 mg/kg), and HME-Zn (HME processed ZnSO as nano-Zn, 80 mg/kg). Read More

Non-Small Cell Carcinoma-Not Otherwise Specified on Cytology Specimens in Patients with Solitary Pulmonary Lesion: Primary Lung Cancer or Metastatic Cancer?

J Cytol 2021 Jan-Mar;38(1):8-13. Epub 2021 Jan 8.

Department of Pathology, Dong-A University College of Medicine, Busan, Korea.

Context: Subtyping of solitary pulmonary lesion (SPL) in small amount of cytology specimen using a limited panel of immunohistochemistry (IHC) markers is very important to the correct choice of treatment. This study was performed to categorize non-small cell carcinoma-not otherwise specified (NSCC-NOS) on cytology in patients with SPL, especially with regard to the incidence of metastatic cancer.

Materials And Methods: We reviewed 91 cases, in which a precise morphology-based, lineage-specific IHC-aided subtyping was not possible, that qualified as NSCC-NOS on cytology. Read More
