Megaduodenum in аdults

Résumé fourni par la source

This paper describes a clinical case of a patient with megaduodenum; the condition was detected in adulthood, it developed due to congenital duodenal malformation. A 43-year-old female patient visited A.V. Vishnevsky National Medical Research Center with complaints of nausea and vomiting after eating, which brought her relief. These signs occasionally bothered the patient throughout her life. Based on the examination performed, the patient was diagnosed with a giant duodenal diverticulum and surgical intervention (laparoscopic diverticulectomy) was planned. The obtained intraoperative data evidenced a presenting congenital megaduodenum associated with the duodenum bulb critical stenosis. During the surgical intervention, a duodenotomy was performed, which implied a step-by-step excision of the mucosal-submucosal fold of the duodenal wall with scar tissue at its base with duodenoplasty according to the original technique. The article describes the difficulties of diagnosing the condition and the original surgical treatment option. A brief review of the literature comparing clinical outcomes of patients with a similar nosology is provided.
