Title: Acute duodenal obstruction secondary to intussusception caused by the duodenal
diverticulum: A case report
Version: 0Date: 03 Apr 2020
Reviewer's report:
1. Written English needs to be improved. "The duodenal intussusception is rarely reported and
usually occurs secondary to duodenal organic diseases of the duodenum such as polyps, tumorsand duplication cysts." "intestinal space occupying lesion"2. In Background, "this is first such case to be reported in the English literature." Kindly referhttps://www.gastrojournal.org/article/S0016-5085(81)80068-6/pdf3. Kindly provide references for the below statements;
"Duodenal intussusception is generally transient and non-obstructive"
"retrograde traction may occur as the invagination progresses more distally because of the lack ofmobility of the duodenal wall""The clinical manifestations in adults with duodenal intussusception are usually non-specific andinclude nausea, vomiting and epigastric pain"4. Is it possible that this is a case of gastroduodenal intussusception?5. Kindly provide the histopathological report of the resected specimen.6. The conclusion needs to be revised. "Detailed investigations should be performed to rule outduodenal intussusception in patients with duodenal diverticulum" is inadequate.7. Kindly provide coronal cuts of the CT and well as an axial cut of the CT at the level of thepylorus. The CT image provided is unclear.
