Small intestine protection from radiation by means of a removable adapted prosthesis

American Journal of Surgery
A SezeurM Malafosse


A prosthesis has been designed to protect intestinal loops from radiation when postsurgical radiotherapy is necessary in cancer treatment. It is a silicone balloon that allows the small bowel to be pushed back away from the radiation field, and it is easily removed at the conclusion of radiotherapy. The device was used in 22 patients: 5 retroperitoneal tumors and 17 pelvic cancers. After surgical resection of the tumor, the device is placed either in the retroperitoneal area or in the pelvic cavity. A polyglactine 910 mesh is placed between the spacer and the bowel to prevent incarceration of the loops. The prosthesis can be filled or emptied between each radiation course and finally removed by means of a short incision under local or locoregional anesthesia. The tolerance of the small intestine to radiation therapy has been satisfactory in each case, with a mean follow-up of 24.5 months (range 10 to 73). No modification of biological parameters was observed during the pelvic radiation therapy at 30, 45, and 65 Gy. This device should appears to efficient for prevention of bowel injury during postsurgical radiation in successful treatment of abdominal, pelvic, or retroperitoneal tumors when indicated.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.


Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.


Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
