Summary
The splenic flexure (SF) is most commonly found inferior to the spleen on CT scans. This classification of SF positions can aid surgeons in minimizing complications and improving dissection accuracy.
Area of Science:
- Radiology
- Anatomy
- Surgical Anatomy
Background:
- The anatomical relationship between the splenic flexure (SF) and the spleen is not well-documented in existing literature.
- A detailed, prospective examination of this relationship using computed tomography (CT) scans is lacking.
Purpose of the Study:
- To classify the positional variations of the splenic flexure (SF) relative to the spleen.
- To establish a detailed topographic classification for SF localization.
- To provide a basis for understanding SF anatomical variability.
Main Methods:
- Analysis of 120 consecutive CT scans to determine SF localization.
- Consideration of various patient variables including age, gender, and BMI.
- Development of a dedicated topographic outline for SF classification.
Main Results:
- The SF was classified into three positional types: inferior (I), anterior (A), and posterior (P).
- The inferior (I) position, below the spleen, was observed in 52% of cases.
- Anterior (A) and posterior (P) positions were found in 42% and 8% of cases, respectively.
- No statistically significant correlation was found between SF position and the variables analyzed (p > 0.05).
Conclusions:
- A classification system for SF localization relative to the spleen (inferior, anterior, posterior) was established based on CT findings.
- Understanding the anatomical variability of the SF's position is crucial.
- This knowledge can help minimize surgical complications and enhance the accuracy of surgical dissection.
