RESUMO
PURPOSE: Groin hernias are a common condition that can be treated with various surgical techniques, including open surgery and laparoscopic approaches. Laparoscopic surgery has several advantages but its use is limited due to the complexity of the posterior inguinal region and the need for advanced laparoscopic skills. This paper presents a standardized and systematic approach to trans-abdominal pre-peritoneal (TAPP) groin hernioplasty, which is useful for training young surgeons. METHODS: The paper provides a detailed, step-by-step description of the TAPP based on evidence from literature, anatomical knowledge, and the authors' experience spanning over 30 years. The sample includes 487 hernia repair procedures, with 319 surgeries performed by experienced surgeons and 168 surgeries performed by young surgeons in training. The authors performed a descriptive analysis of their data to provide an overview of the volume of laparoscopic hernioplasty performed. RESULTS: The analysis of the data shows a low complication rate of 0.41% (2/487) and a low recurrence rate of 0.41% (2/487). The median duration of the surgery was 55 min, while the median operation time for surgeons in training was 93 min, specifically 83 min for unilateral hernia and 115 min for bilateral hernia. CONCLUSIONS: The TAPP procedure appears, to date, comparable to the open inguinal approach in terms of recurrence, postoperative pain and speed of postoperative recovery. In this paper, the authors challenge the belief that TAPP is not suitable for surgeons in training. They advocate for a training pathway that involves gradually building surgical skills and expertise. This approach requires approximately 100 procedures to achieve proficiency.

The spleen is a lymphoid organ that has been poorly studied compared to other solid organs, probably because it has been considered a useless and unnecessary part of the body. For many centuries it has been considered a mysterious organ with uncertain functions. The first descriptions of the spleen date back to ancient ages. The spleen has been considered as a reservoir of liquids, strictly linked to stomach digestion, and in different cultures, it has been linked to melancholy and sadness due to the accumulation of black bile (humoral doctrine). A detailed anatomic description was first made by Vesalius during the Renaissance, and further implemented with the description of its microscopic structure by Marcello Malpighi in the seventeenth century. The first case reports regarding spleen functions and pathology regarded common causes of splenomegaly, such as malaria infection, and traumatic rupture. At the beginning of the last century, the pivotal concepts of hypo- and hypersplenism were introduced, along with the cumulating evidence of the relation between spleen removal and increased susceptibility to infections and thromboembolism. The study of hyposplenic states, which occur much more commonly than originally thought in many immune-mediated disorders, has rapidly increased after the validation of a simple method for assessing spleen function, namely pitted red cell count. In recent years, spleen morphology, in particular spleen stiffness, has been proposed as a marker of portal hypertension. In this paper, we retrace the fundamental steps of the discovery of the functions of the spleen.
