Selection criteria for preoperative endoscopic retrograde cholangiopancreatography before laparoscopic cholecystectomy and endoscopic treatment of bile duct stones. Results of a retrospective; single center study between 1996-2002 [PDF]

, 2004
AIM: The optimal treatment for bile duct stones (in terms of cost, complications and accuracy) is unclear. The aim of our study was to determine the predictive factors for preoperative endoscopic retrograde cholangiopancreatography (ERCP).

Bleeding Meckel’s Diverticulum in a 33-Year-Old Female Diagnosed with Video Capsule Endoscopy and a Technetium-99 m Pertechnetate Scan with a Favorable Response to H2 Blocker and PPI

Case Reports in Gastrointestinal Medicine, 2021
Meckel’s diverticulum is a true diverticulum consisting of all three layers of the small intestine resulting from incomplete regression of the vitelline duct.

Regressing vitelline vein and the initial development of the superior mesenteric vein in human embryos

, 2017
The superior mesenteric vein was considered to develop in situ in the midgut mesentery secondary to regression of the left vitelline vein. We revisited the morphology using serial sections of 20 embryos at 5-6 weeks (CRL 9-15 mm).

The junction between the midgut and hindgut co‐localizes with the rectosigmoid junction

Journal of Anatomy, Volume 249, Issue 1, Page 33-53, July 2026.
At 5 weeks of development, the midgut has formed its primary loop (left). It is well established that the midgut is bounded cranially by the caudal end of the ventral mesentery and the presence of the common bile duct, but its caudal boundary remains to be established.

Small bowel segment with Meckel’s diverticulum volvulus related to short mesodiverticular band: a case report

Journal of Medical Case Reports, 2023
Background Meckel’s diverticulum is a remnant of the omphalomesenteric duct and occurs in only about 2% of people. Mesodiverticular band is the congenital remnant of the vitelline artery and is an even less often occurring phenomenon.

Analytical modelling of sound transmission in a lined duct

, 2013
The focus of this thesis is on the prediction of sound attenuation through a lined duct, based on a mathematical model. Ducts with a single section as well as multi-segmented sections are discussed. The duct of interest has a rectangular cross-section as

Radiologic Imaging in Meckel Diverticulum Complications

Journal of Medical Ultrasound, 2015
In 1809, Johann Friedrich Meckel the Younger described the most common congenital small bowel anomaly, which was named after him; however, the radiologic manifestations and interventional guidelines related to this entity are still limited to a few large-

Meckel's Diverticulum Causing Sigmoid Knotting and Closed‐Loop Obstruction: A Rare Case Report From a Resource‐Limited Setting

Clinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT Meckel's diverticulum rarely causes large bowel obstruction through a fibrous band, leading to sigmoid knotting and closed‐loop gangrene. In patients presenting with acute intestinal obstruction without prior abdominal surgery, this etiology should be considered.

Morphology of the patent arterial duct : features relevant to treatment [PDF]

, 2008
Patent ductus arteriosus (PDA), one of the most common congenital heart defects, is an abnormal persistence of a patent lumen in the arterial duct due to an arrest of the natural process of closure after it has served its function as a vital channel ...
