Laparoscopy as a Diagnostic Tool in Abdominal Conditions: An Observational Study

Background: Diagnostic Laparoscopy has emerged as a vital tool with high diagnostic accuracy, particularly in cases where traditional imaging modalities fail to provide definitive answers. The use of laparoscopy as a diagnostic tool is advantageous where the etiology remains unclear after routine workup. Studies have shown that diagnostic laparoscopy has a high sensitivity and specificity in identifying intra-abdominal pathologies. The ability to perform therapeutic interventions during the same procedure further enhances its utility in improving patient outcomes. Moreover, the introduction of laparoscopic ultrasonography and fluorescence-guided surgery, has further expanded its diagnostic capabilities. Limitations are highly operator and technology dependent with few relative and absolute contraindications. Aim: This study aims to evaluate the effectiveness of laparoscopy as a diagnostic tool in various abdominal conditions, focusing on its utility in detecting pathologies that remain unresolved through conventional radiological investigations. Materials and Methods: An observational study was conducted in the Department of General Surgery on adult patients undergoing diagnostic laparoscopy for abdominal conditions. Preoperative workup encompassed a comprehensive assessment, including history taking, physical examination, relevant laboratory tests, abdominal ultrasound, X-ray, Contrast Enhanced Computed Tomography(CECT whole abdomen) and when necessary Magnetic Resonance tomography(MRI). The study aimed to enroll a sample size of 117 patients based on statistical calculations. Data collected during the study period was analysed using appropriate statistics. The diagnostic laparoscopy procedure followed standard techniques under general anaesthesia with specific patient and surgeon positioning. Results: The diagnostic laparoscopy yielded pathological findings across the study population. The majority of the study population was female (88%) and aged between 41-50 years (46.2%). Among the 117 patients examined, 100 (85.47%) displayed discernible pathology, while 17 (14.53%) showed no detectable abnormalities. The pathological spectrum included a range of conditions: ovarian cysts were diagnosed in 19 patients, endometriosis in 27 patients, Koch’s abdomen in 9 patients, Meckel’s diverticulum in 3 patients, mesenteric lymphadenitis in 10 patients, ruptured liver abscess in 7 patients, appendicular pathology (including inflamed appendix and appendicular perforation) in 5 patients, mesenteric cyst in 3 patients, adhesions (fibrous, flimsy and band adhesions) in 15 patients, and traumatic visceral injuries (splenic injury) in 2 patients. Conclusion: The study highlighted laparoscopy’s crucial role in diagnosing and managing abdominal conditions. It emphasized its minimally invasive nature, precise visualization, and efficacy across demographics and socioeconomic groups. Laparoscopy was shown to reduce hospitalization times, post-operative pain, and overall morbidity and mortality rates, effective in identifying predictive factors for pathology detection, contributing valuable insights into improving diagnostic accuracy and optimizing patient outcomes, making it cost-effective and therapeutically beneficial. Recommendation: Laparoscopy should be considered a primary diagnostic tool in cases of unresolved abdominal conditions, particularly for patients with a history of addiction. Future studies should focus on refining the selection criteria for diagnostic laparoscopy to maximize its diagnostic yield and minimize unnecessary procedures.
