Intraoperative esophageal manometry in surgical treatment of achalasia: a reappraisal

Abstract

Intraoperative Esophageal Manometry is used during surgery for gastroesophageal reflux disease to obtain a better lower esophageal sphincter pressure, or during the Heller procedure for achalasia to verify the myotomy. The effectiveness of this manometry is not explicit. From 1977 to 1987, 58 patients underwent surgery for achalasia at our Institution. A transabdominal Heller's myotomy and a modified Dor's anterior fundoplication were performed in all cases. During the operation, Lower Esophageal Sphincter Pressure was measured in 38 patients (A group) to verify the completeness of the càr-diomyotomy; the fundoplication-induced pressure increase was also recorded. Twenty patients (B group) underwent surgery without intraoperative manometry. Forty-six patients (30 of A group and 16 of B group) were followed up for 24 to 120 months (median 68 months) by means of a clinical questionnaire, barium meal, manometry and 24-hour esophageal pH monitoring. In 21 cases, intraoperative manometry showed the completeness of the myotomy at the first record, while in the remaining 17 it revealed the persistence of a High Pressure Zone; in these, a more accurate incision of the muscle layers on the anterior surface of the esophagus was subsequen...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.
