Laparoscopic Surgery for Superior Mesenteric Artery Syndrome

Area of Science:

• Gastroenterology
• Surgical Innovation
• Clinical Outcomes

Background:

• Superior Mesenteric Artery Syndrome (SMAS) is a rare gastrointestinal condition.
• Surgical intervention is considered when conservative treatments are ineffective.
• Laparoscopic approaches are increasingly explored for SMAS management.

Purpose of the Study:

• To evaluate the safety and long-term efficacy of laparoscopic surgery for SMAS.
• To compare outcomes across different laparoscopic surgical techniques for SMAS.
• To determine the effectiveness of laparoscopic surgery in improving patient symptoms and nutritional status.

Main Methods:

• Retrospective analysis of 66 patients with SMAS treated between 2010 and 2020.
• Patients were categorized into three laparoscopic surgical groups: duodenojejunostomy, gastrojejunostomy, or combined procedures.
• Data collected included patient demographics, surgical details, and postoperative outcomes.

Main Results:

• All laparoscopic procedures were successfully completed.
• A median follow-up of 65 months demonstrated significant symptom score reduction (32 to 8, p < 0.0001).
• Body Mass Index (BMI) significantly increased from 17.2 kg/m² to 21.8 kg/m² (p < 0.0001).

Conclusions:

• Laparoscopic surgery is a safe and effective treatment for SMAS after conservative measures fail.
• Individualized surgical technique selection based on patient history and symptoms is crucial.
• This study represents the largest single-center series of laparoscopic procedures for SMAS.
