The small bowel in its hammock: how to avoid irradiation thanks to the sigmoid

Sabine IrtanSabine Sarnacki


High-dose irradiation is the cornerstone treatment of bone cancers of the pelvic rim. To protect the small bowel from irradiation and following consequences, we described the laparoscopic use of the sigmoid to perform a hammock. Three patients were diagnosed with metastatic Ewing's sarcoma, localized malignant peripheral nerve sheath tumor, and localized BCOR-CCNB3 (Ewing-like) sarcoma of the pelvic rim at 13.1, 5.7, and 12.9 years, respectively. After neoadjuvant chemotherapy, the 2 female patients underwent a hemisacrectomy under S2 only by the posterior approach, whereas no orthopedic surgery was required for the male patient because of excellent local response to chemotherapy. A 54-Gy intensity-modulated radiotherapy of the posterior part of the pelvis was intended for all patients. The laparoscopic procedure consisted in the fixation of the sigmoid loop to the anterior parietal wall on a transverse line just below the umbilicus, associated with a colostomy in the right iliac fossa. The anterior transposition of the two ovaries, uterus, and rectum and the dissection of left iliac vessels to move them anteriorly were added in female patients. Stomas were closed around 6 months after completion of the radiotherapy course, ass...Continue Reading

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.
