Laparoscopic-assisted resection of giant sigmoid lipoma under colonoscopic guidance

Surgical Endoscopy
R LadurnerK Hallfeld


Colonic lipomata are rare and mostly asymptomatic lesions; but as they become larger they may produce abdominal pain, constipation, diarrhea, hemorrhage, and intussusception. We report the case of a 75-year-old man who suffered from nonspecific recurrent abdominal pain in the left upper and lower quadrants and had variable episodes of diarrhea and constipation of 4 weeks' duration. During colonoscopy, a giant intraluminal polyp was diagnosed at 35 cm. Abdominal helical computed tomography (CT) revealed a constipating colonic tumor with a diameter of >or=50 mm and density values equal to fat. During laparoscopic surgery in the lithotomy position, the sigmoid and the descending colon were mobilized using a Harmonic scalpel. The origin of the polyp was localized precisely under colonoscopic guidance. The former 12-mm incision in the left lower quadrant was expanded to approximately 70 mm for extracorporal tumor resection. The left and sigmoid colon resections were carried out, and the polyp was removed by full-wall excision. After closure with a single-layer suture, the colon was pushed back into the peritoneal cavity. The patient had an uneventful recovery and was discharged 10 days postoperatively. Histology confirmed a benign l...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.
