Elective Laparoscopic Sigmoidectomy Reduces IL-6 Serum Levels in Uncomplicated Recurrent Diverticulitis

Area of Science:

• Gastroenterology
• Surgical Oncology
• Inflammatory Diseases

Background:

• Recurrent diverticulitis is a chronic condition lacking clear markers for monitoring during quiescent phases.
• The study investigates the role of serum inflammatory markers, specifically IL-6, in quiescent diverticulitis.
• Hypothesizes elevated IL-6 levels during quiescent phases that decrease post-surgery.

Purpose of the Study:

• To assess IL-6 serum levels and quality of life (QoL) before and 6 months after surgery.
• To evaluate the impact of elective laparoscopic sigmoidectomy on inflammatory markers in recurrent diverticulitis.
• To determine if IL-6 reduction post-surgery correlates with QoL improvement.

Main Methods:

• An epidemiological study involving 30 patients with uncomplicated recurrent diverticulitis.
• Patients underwent elective laparoscopic sigmoidectomy.
• IL-6 levels and QoL (using GIQLI) were measured preoperatively and 6 months postoperatively.

Main Results:

• Mean preoperative IL-6 levels were 9.5 pg/ml, significantly decreasing to 4.5 pg/ml post-surgery (p=0.0085).
• Preoperative QoL (GIQLI score) was 98, significantly improving to 112 post-surgery (p=0.043).
• A significant reduction in IL-6 and a significant improvement in QoL were observed.

Conclusions:

• Elective laparoscopic sigmoidectomy leads to a significant reduction in serum IL-6 levels.
• Surgical removal of the inflamed sigmoid colon appears to decrease systemic inflammation.
• Improved QoL is observed post-surgery, suggesting a positive impact on patient well-being.
