Management of solitary cecum diverticulitis - Single-Center Experience.

<b> Objective: </b> Cecal diverticulitis may be encountered as a real etiological factor in 1/300 appendectomies. Differential diagnosis of acute appendicitis and cecal diverticulitis is crucial because of the different treatment methods. Our aim is to reveal the importance of distinguishing acute appendicitis from cecal diverticulitis.

WHY DIAGNOSTIC LAPAROSCOPY.

Introduction: Abdominal pain requires rapid diagnosis and treatment, especially in emergency circumstances. Sometimes the diagnosis of the disease cannot be accomplished with laboratory and imaging methods, and an invasive procedure such as diagnostic laparoscopy may be required to obtain a diagnosis. Diagnostic laparoscopy is also performed therapeutically, but laparotomy is inevitable in some cases.
