How *The Pyloric Sphincteric Cylinder in Health and Disease* Was Published Online and What Its Copyright Terms Are

The book was first published in print by Springer-Verlag (Berlin Heidelberg) in 1993, under ISBN 3-540-55814-4 (Springer-Verlag Berlin Heidelberg New York) and ISBN 3-387-55814-4 (Springer-Verlag New York Berlin Heidelberg). After Springer-Verlag decided to publish the work in full on the Internet, it returned full copyright to the author, Dr. AD Keet. The Internet edition was edited and published in 1998 by PLiG. Copyright is reserved: no part of the publication may be reproduced, stored in a retrieval system, or transmitted in any form without prior permission from the current publishers.

Publication timeline

The stated aim of the online release was to make the work easily accessible worldwide for research purposes.

Author and origin of the work

The author, AD Keet, holds M.B. Ch.B. (University of Cape Town), M.D. (University of Amsterdam), and Ph.D. (Med.) (University of Stellenbosch). The project originated in and was managed from the Department of Roentgenology, Tygerberg Hospital — the academic hospital of the Faculty of Medicine, University of Stellenbosch, South Africa.

What the book covers

The treatise develops the concept of a sphincteric cylinder (as opposed to a sphincteric ring) at the pylorus. It argues that many physiological events involving the pylorus — gastric motility, trituration, emptying of liquids and solids, duodeno-gastric reflux — can be elucidated by considering the stomach anatomy described by Cunningham (1906), Forssell (1913), and Torgersen (1942). The same applies to pathological conditions such as gastric and duodenal ulceration, some types of gastritis, diabetes mellitus, and pyloric carcinoma.

Findings from gastroscopy, ultrasonography, manometry, radionuclide scintigraphy, myoelectric activity, and roentgenology are discussed and compared. Roentgenology (barium meal or upper gastrointestinal series) was used as an investigative rather than a diagnostic tool; the author notes this does not deny that endoscopy is currently the investigation of choice in upper gastrointestinal pathology.

The online table of contents runs to 39 chapters, from introductory material and anatomy (stomach and duodenal walls, submucous coat, mucosa, electrical potential difference at the gastroduodenal mucosal junction, arteries/veins/lymphatics, nerves, regulatory peptides) through investigative methods (ultrasonography, radiography, gastroscopy, manometry, myoelectric activity, radionuclides) to clinical conditions (pylorospasm, congenital anomalies, infantile and adult hypertrophic pyloric stenosis, duodenogastric reflux, gastritis and erosions, gastric and duodenal ulceration, pyloroduodenal fistula, GERD, pyloric carcinoma, malignant lymphoma, diabetes mellitus, mucosal prolapse, and acid corrosive injuries).
