Laparoscopy and intraoperative enteroscopy, a helpful tool in a rare tumor (inflammatory fibroid polyp) of the small bowel. A case report.

Ann Med Surg (Lond) 2021 Jun 12;66:102355. Epub 2021 May 12.

Universidad Central del Ecuador (UCE), Quito-Ecuador.

Introduction And Importance: Inflammatory fibroid polyps (IFPs) are rare, benign tumors that can arise throughout the gastrointestinal tract, they are usually asymptomatic, and clinical presentation depends on the site of involvement. Gastric and colon IFPs are traditionally identified incidentally, whereas small intestinal lesions are often encountered in the setting of intussusception or during imaging studies. Complete resection via endoscopy or surgery is recommended. Read More

Assessment of structural protein expression by FTIR and biochemical assays as biomarkers of metabolites response in gastric and colon cancer.

Talanta 2021 Aug 1;231:122353. Epub 2021 Apr 1.

Institute of Nuclear Physics Polish Academy of Science, 31-342, Krakow, Poland. Electronic address:

Colon and gastric cancers are the widespread benign types of cancers which are synchronous and metachronous neoplasms. In terms of the progression and progress of the disease, metabolic processes and differentiation in protein structures have an important role in for treatment of the disease. In this study we proposed to investigate the metabolic process and the differentiation of protein secondary structure among colon and gastric cancer as well as healthy controls using biochemistry and Fourier Transform InfraRed spectroscopy (FTIR) methods.

Gastric linitis plastica due to signet-ring cell carcinoma with Krukenberg tumors diagnosed by endoscopic ultrasound-guided fine-needle aspiration.

Clin J Gastroenterol 2021 Mar 19. Epub 2021 Mar 19.

Department of Gastroenterology, St. Luke's International Hospital, 9-1 Akashicho, Chuo-ku, Tokyo, 104-8560, Japan.

Gut Liver 2021 Mar 15. Epub 2021 Mar 15.

Department of Internal Medicine, Pusan National University College of Medicine, and Biomedical Research Institute, Pusan National University Hospital, Busan, Korea.

Subepithelial tumors (SETs) are commonly encountered during upper gastrointestinal endoscopy, especially during national gastric cancer screening programs in Korea. Although the majority of SETs are benign, endoscopists harbor concerns regarding whether a SET is benign or malignant because the diagnosis cannot be established on the basis of routine endoscopic biopsy findings. The differential diagnosis of SETs is important, beginning with meticulous endoscopic examination, including the evaluation of the location, macroscopic shape, color, surface characteristics, mobility, consistency, and size of the tumors.

Gan To Kagaku Ryoho 2021 Feb;48(2):176-180

Graduate School of Pharmaceutical Sciences, The University of Tokyo.

In this paper, novel rapid cancer imaging techniques using activatable fluorescent probes are showcased, whose fluorescence characteristics are significantly altered to distinguish between cancer sites, which was developed by using unique probe precision design methods established by the authors. The strategy is to develop probes that target enzymes whose activity has been reported to be enhanced in cancer sites, or to find the most suitable probes from a group of developed probes by screening using actual clinical specimens. Several medical technologies have been developed that enable selective detection of cancer sites within minutes by simply spraying the probes on suspected cancer sites. Read More

Local Heat Treatment for Suppressing Gastroduodenal Stent-Induced Tissue Hyperplasia Using Nanofunctionalized Self-Expandable Metallic Stent in Rat Gastric Outlet Model.

ACS Biomater Sci Eng 2020 04 19;6(4):2450-2458. Epub 2020 Mar 19.

Departments of Radiology, Asan Medical Center, University of Ulsan College of Medicine, 88 Olympic-ro 43-gil, Songpa-gu, Seoul 05505, Republic of Korea.

Despite the promising results from the placement of covered or uncovered self-expandable metallic stent (SEMS) as a nonsurgical therapeutic option for the malignant gastric outlet obstruction (GOO), the long patency of the stent is still limited because of stent-induced tissue hyperplasia. Here, a local heat treatment using a nanofunctionalized SEMS is proposed for suppressing stent-induced tissue hyperplasia during GOO treatment. Highly efficient photothermal gold nanoparticle (GNP) transducer-coated SEMSs (GNP-SEMSs) were prepared for local heat treatment in rat gastric outlet. Read More

The Landmark Series: Desmoid.

Ann Surg Oncol 2021 Mar 1;28(3):1682-1689. Epub 2021 Jan 1.

Sarcoma Unit, Mannheim University Medical Center, University of Heidelberg, Mannheim, Germany.

Desmoid-type fibromatosis represents a challenge in the landscape of surgical oncology, for several reasons. The tumors can be infiltrative and locally aggressive, surgery may be morbid, and patients are usually young, and thus treatment sequelae must be managed for decades. Desmoids do not have metastatic potential, therefore management strategies for desmoids have evolved to employ frontline treatments that are largely non-operative. Read More
