Using Materialise's interactive medical image control system to reconstruct a model of a patient with rectal cancer and situs inversus totalis: A case report

Abstract

Situs inversus totalis (SIT) is a rare congenital anomaly that refers to a completely reversed location of abdominal and thoracic organs. An extremely small number of patients with this condition, especially those with rectal neoplasms, have been reported. Surgery in these patients is technically challenging. Therefore, we reconstructed a three-dimensional (3D) digital model with the Materialise's interactive medical image control system (Mimics) as a guide for laparoscopic resection. We report the case of a 68-year-old woman with rectal neoplasms and SIT diagnosed by electronic colonoscopy biopsy and enhanced computed tomography (CT), which showed that there was a soft tissue mass protruding into the lumen in the lower rectal segment, a lesion that involved the serosal layer, multiple enlarged peripheral lymph nodes, and visceral situs abnormalities. Based on the CT images, we reconstructed a 3D model with Mimics to assist with our surgical planning. Then, we performed laparoscopy-assisted radical resection of the rectal neoplasms and total excision of the lesion. Adjuvant chemotherapy with the XELOX regimen (oxaliplatin 150 mg, D1 + Xeloda 1.0 g, Bid, D1-14) was initiated 1 mo after the operation. The patient recovered well a...Continue Reading

COVID-19

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

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.

Microbicide

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.
