Diagnostic laparoscopy: reducing the number of normal appendectomies

Area of Science:

• Surgical innovation
• Emergency medicine
• Gastrointestinal surgery

Background:

• Acute right iliac fossa pain is a common presentation in emergency departments.
• Differentiating appendicitis from other causes of pain can be challenging, leading to potential diagnostic delays or unnecessary surgeries.
• Unnecessary appendectomies contribute to healthcare costs and patient morbidity.

Purpose of the Study:

• To evaluate the efficacy of a selective diagnostic laparoscopy policy in reducing normal appendectomies for acute right iliac fossa pain.
• To compare the rate of unnecessary appendectomies between a diagnostic laparoscopy group and a control group undergoing laparotomy.
• To assess the impact of diagnostic laparoscopy on perforation rates.

Main Methods:

• A prospective, controlled study involving patients admitted with acute right iliac fossa pain.
• The study group received a selective policy of diagnostic laparoscopy for equivocal cases after 8-12 hours of observation.
• The control group underwent laparotomy for equivocal cases after a similar observation period.

Main Results:

• In the study group, 28 of 102 patients required diagnostic laparoscopy; 18 had appendicitis, and 10 had normal appendices, avoiding unnecessary laparotomies.
• The control group had a normal appendectomy rate of 15.7% (P < 0.05).
• No significant difference in perforation incidence was observed between the groups.

Conclusions:

• Selective use of diagnostic laparoscopy in equivocal cases of acute right iliac fossa pain significantly reduces unnecessary appendectomies.
• This strategy effectively avoids unneeded surgeries without compromising patient safety regarding perforation rates.
• Diagnostic laparoscopy offers a valuable tool for improving diagnostic accuracy and resource utilization in suspected appendicitis.
