Insights
This case study details a 10-year-old boy with congenital superior mesenteric artery syndrome (SMAS), presenting with severe gastrointestinal issues. Surgical intervention, the Koecher maneuver, successfully resolved symptoms, offering long-term relief.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Vascular Anatomy
Background:
- Superior Mesenteric Artery Syndrome (SMAS) is a rare condition causing duodenal obstruction.
- Congenital SMAS, though uncommon, presents diagnostic challenges in pediatric patients.
- Recurrent abdominal pain, distension, and vomiting are key symptoms requiring thorough investigation.
Observation:
- A 10-year-old boy experienced persistent gastrointestinal distress since birth, worsening over two years.
- Diagnostic imaging, including barium studies and CT scans, confirmed SMAS.
- The patient had no significant weight loss, prior surgeries, or other concurrent illnesses.
Findings:
- Surgical treatment via laparotomy and the Koecher maneuver successfully released the obstructed duodenum.
- The procedure involved dividing the Treitz ligament to decompress the aorto-mesenteric space.
- Post-operative follow-up over five years demonstrated an excellent clinical outcome.
Implications:
- This case highlights the importance of considering congenital SMAS in pediatric patients with unexplained chronic gastrointestinal symptoms.
- The Koecher maneuver is an effective surgical approach for treating SMAS.
- Early diagnosis and surgical intervention can lead to significant long-term improvement in quality of life.
Abstract:
We describe a case of a 10 yr old boy, who suffered from gastroesophageal reflux in the neonatal period and from recurrent abdominal pain, epigastric distension and vomiting since birth, but with an increase in this clinic in the last two years, especially in the last five months, without suffering weight loss, having operations or other illnesses. After the diagnosis of superior mesenteric artery syndrome was confirmed by a superior barium series and a CT-scan, a laparotomy was performed, carrying out the Koecher manoeuvre, cutting the Treitz ligament near of the 4th part of the duodenum until descend that and freeing the aorto-mesenteric space. The follow up after 5 years showed an excellent clinical evolution. In our opinion, this case should be considered to be of congenital origin, but without other associated abdominal anomalies. The possible different interventions are also discussed.
