RÉSUMÉ

PURPOSE: Emergency treatment of acute diverticulitis remains a hazy field. Despite a number of clinical studies, randomized controlled trials (RCTs), guidelines and surgical societies recommendations, the most critical hot topics have yet to be addressed. METHODS: Literature research from 1963 until today was performed. Data regarding the principal RCTs and observational studies were summarized in descriptive tables. In particular we aimed to focus on the following topics: the role of laparoscopy, the acute care setting, the RCTs, guidelines, observational studies and classifications proposed by literature, the problem in case of a pandemic, and the importance of adapting treatment /place/surgeon conditions. RESULTS: In the evaluation of these points we did not try to find any prospective evolution of the concepts achievements. On the contrary we simply report the individuals strands of research from a retrospective point of view, similarly to what Steve Jobes said: "you can't connect the dots looking forward; you can only connect them looking backwards. So you have to trust that the dots will somehow connect in your future". We have finally obtained what can be defined "a narrative review of the literature on diverticulitis". CONCLUSIONS: Not only evidence-based medicine but also the contextualization, as also the role of 'competent' surgeons, should guide to novel approach in acute diverticulitis management.

RÉSUMÉ

Portosystemic shunts cause severe secondary effects, so that arterializations of the portal stump are planned to increase the blood supply to the liver. The aim of this study was to verify the technical feasibility of arterialization of the portal stump with the right renal artery in order to obtain a valid experimental model to study the pathophysiology of arterial revascularization of the liver. Twenty rats underwent end-to-side portocaval shunt + end-to-end anastomosis between the right renal artery and portal stump; another 20 rats were subjected to the same surgical procedure, but the portal stump underwent a reduction in size. In our study, both techniques gave good results, but the use of an operating microscope and good microsurgical training were essential in achieving a good patency rate (78.3%).

RÉSUMÉ

Our aim was to evaluate liver damage after ischemia and reperfusion, and at the same time test the effectiveness of some drugs in preventing these alterations. For this study, we utilized 50 rats divided into four groups: three underwent hepatic ischemia through occlusion of the portal vein and hepatic artery for 30 min, and one underwent a sham operation. In all groups, hepatic enzymes and bilirubine were tested at 2 h, 3 h, 4 h, 24 h, and 30 h. The drugs utilized were: L-arginine, donor of nitric oxide, and L-canavanine, inhibitor of nitric oxide synthase (NOS). Our data showed that the drugs tested could make an improvement in hepatic function after ischemia/reperfusion, preventing its damage. These preliminary results could suggest a clinical application in order to prolong ischemic period during liver transplantation or liver resection in cirrhotic patients.
