Abstract Body :
Introduction:Laparoscopic cholecystectomy is a common surgical procedure for gallbladder removal, frequently performed by surgical trainees, including medical students. Objective: To enhance the anatomical understanding and practical skills required for this surgery, our objective was to identify and elucidate the distinct components of the anterior abdominal wall and the spatial orientation of major vasculature in relation to trocar insertion sites.Materials and Methods:Cadaveric dissection served as the primary method for our study. We meticulously explored the layers of the anterior abdominal wall, including the skin, subcutaneous tissue, superficial fascia, rectus sheath, and peritoneum. The major focus was on establishing a deeper understanding of optimal entry points for laparoscopic trocars. We also identified and examined the path of the superficial epigastric artery and vein. High-resolution photographs and detailed descriptions were employed to document our findings.Results:Our study yielded a comprehensive account of the anatomical components of the anterior abdominal wall and their relationships to common trocar sites. We provided a clear understanding of the distinct layers, allowing medical students to better recognize them during trocar placement. Additionally, we illustrated the precise spatial orientation of important vascular structures, offering valuable guidance for trocar insertion. The anatomical details were reinforced with visual evidence to enhance comprehension.Conclusion:In conclusion, our study highlights the critical importance of thorough knowledge of the anterior abdominal wall's components and the spatial orientation of major vasculature for laparoscopic cholecystectomy, particularly with regards to medical students. This knowledge is fundamental for safe and effective surgical practice, and its application is directly aligned with our study's primary objective of enhancing anatomical education for aspiring surgeons.Significance/Implication:Our research holds significant implications for medical education and the training of future surgeons. Medical students and surgical trainees can benefit from this detailed anatomical understanding, leading to increased patient safety and improved surgical proficiency. The ability to identify appropriate trocar insertion sites and minimize the risk of vascular injury is paramount. Moreover, our findings lay the groundwork for further research aimed at refining surgical training programs and ultimately improving patient outcomes in laparoscopic cholecystectomy.
