Ductus diverticulum is a focal bulge at the anteromedial aspect of the aortic isthmus, visualised in 9% of adults. It is critical to identify this normal variant and distinguish it from a post-traumatic false aneurysm, which also occurs most commonly at the aortic isthmus (88%). The classic ductus diverticulum has smooth, uninterrupted margins and gently sloping symmetric shoulders; in contrast, false aneurysms have a variety of shapes and sizes with sharp margins and often contain linear defects. Compared with the classic ductus diverticulum, the atypical ductus diverticulum has a shorter and steeper slope superiorly and a more classic gentle slope inferiorly. However, both shoulders have smooth, uninterrupted margins, an important feature that distinguishes this variant from true injury.
Meckel Diverticulum
Sherif Emil in Clinical Pediatric Surgery: A Case-Based Interactive Approach, 2019
In a patient with painless gastrointestinal gastrointestinal bleeding and no other infectious symptoms or signs, such as diarrhea, abdominal pain, fever, or abdominal tenderness, Meckel diverticulum remains the most likely etiology. The nodular areas most likely correspond to the region of ectopic mucosa. In cases of intestinal ulceration due to a Meckel diverticulum, surgical dictum has been to perform a segmental resection, fearing that the ulcer may be left behind to cause recurrent bleeding if it is at the base of the diverticulum or opposite the diverticulum on the mesenteric side of the intestine. Meckel diverticulum, a true diverticulum containing all layers of the bowel wall, is named after Johann Meckel, a German anatomist who described its anatomy and embryology in 1809. The diverticulum is by far the most common congenital anomaly resulting from failure of involution of the vitelline or omphalomesenteric duct, which connects the midgut to the yolk sac until approximately the seventh week of gestation.
Meckel’s diverticulum
Brice Antao, S Irish Michael, Anthony Lander, S Rothenberg MD Steven in Succeeding in Paediatric Surgery Examinations, 2017
Meckel's diverticulum is the most common vitelline duct abnormality. Abnormal regression of the vitelline duct can also give rise to other abnormalities. Most patients with Meckel's diverticulum are asymptomatic. Approximately 4%–16% of patients have related symptoms. The most common signs and symptoms of Meckel's diverticulum are bleeding, obstruction and inflammation. Meckel's diverticulum acts as a pathological lead point and should be suspected in all cases of intussusception occurring in older children. Inflammation of Meckel's diverticulum presents in older children and can mimic appendicitis. Maydl's hernia and Richter's hernia are not related to a Meckel's diverticulum. The treatment for Meckel's diverticulum is either a simple diverticulectomy or small-bowel resection with end-to-end anastomosis. A large number of Meckel's diverticulums would have to be excised to prevent one death. Elective excision of incidental Meckel's diverticulum is not recommended in cases highly susceptible to sepsis.
Meckel’s diverticulum in an adult with iron deficiency

Meckel’s diverticulum is a true diverticulum caused by the incomplete obliteration of the vitelline duct during gestation. It is the most common congenital malformation of the gastrointestinal tract. Meckel’s diverticulum is a rare presentation in adults, especially because symptomatic patients present in early childhood. We present a 57-year-old woman with symptomatic iron deficiency after recent nonsteroidal anti-inflammatory use. After normal upper and lower endoscopy, a capsule endoscopy showed an oozing polyp in the distal ileum. The small bowel was surgically resected, and histopathology confirmed Meckel’s diverticulum as the cause of her small bowel bleeding. Rare causes such as Meckel’s diverticulum should be kept in mind in the differential diagnosis for patients with suspected small bowel bleeding.

ABSTRACT We report a review of 208 cases of Meckel's diverticulum among pediatric patients from one single institution. One of the aims of this report is to highlight the different diagnostic modalities of Meckel's diverticulum since a majority of cases is undiagnosed prior to surgery. Our review shows 58 cases containing gastric and/or pancreatic heterotopic tissue, including two unique cases. The first case reported is a desmoid tumor arising at the tip of diverticulum, a case that, to our knowledge, has not been previously reported. The second case involves a female patient appearing with an acute abdomen thought to be appendicitis, instead surgery revealed a diverticulum arising from the ileum. The cause of acute abdomen was due to gonococcal infection. In conclusion, we hope that this large series of Meckel's cases will enrich our readers on the differential diagnosis and preoperative diagnostic techniques of Meckels' diverticulum.
Oesophageal achalasia combined with epiphrenic diverticulum:A Case Report
Published in Scandinavian Journal of Thoracic and Cardiovascular Surgery, 1988
Peter C. Rasmussen, Bent S. Jensen, Agnes Winther
A case is presented in which oesophageal achalasia combined with epiphrenic diverticulum caused severe and progressive symptoms, including gross nutritional disturbance. Resection of the diverticulum and esophagomyotomy gave an excellent result.
