Superior mesenteric artery syndrome: where do we stand today?

Area of Science:

• Gastroenterology
• Surgical Gastroenterology
• Medical Diagnostics

Background:

• Limited recent data exists on Superior Mesenteric Artery Syndrome (SMAS).
• Current medical advancements necessitate updated studies on SMAS diagnosis and treatment.
• This study addresses the need for contemporary SMAS research.

Purpose of the Study:

• To document the clinical features and outcomes of SMAS.
• To analyze diagnostic modalities and management strategies for SMAS.
• To provide an updated perspective on SMAS based on recent cases.

Main Methods:

• Retrospective collection of 80 SMAS cases from 2000-2009 across seven South Korean university hospitals.
• Analysis of patient demographics, comorbidities, diagnostic methods, and treatment outcomes.
• Review of both medical and surgical management approaches.

Main Results:

• The median BMI at diagnosis was 17.4 kg/m²; 50% of patients had comorbidities.
• Computerized tomography (CT) was the primary diagnostic tool (93.8%).
• Medical management achieved a 71.3% success rate with a 15.8% recurrence rate; surgery had a 92.9% success rate, with laparoscopic duodenojejunostomy being most common.

Conclusions:

• This is the largest case series detailing SMAS clinical features and management outcomes.
• Laparoscopic duodenojejunostomy is the preferred surgical intervention for refractory SMAS.
• The findings offer insights into contemporary SMAS diagnosis and treatment efficacy.
