Background: This systematic review aims to investigate whether percutaneous transhepatic gallbladder biliary drainage (PTGBD) is superior to emergency cholecystectomy (EC) as a definitive treatment in high-risk patients with acute cholecystitis (AC). Material and Methods: A systematic literature search was performed until December 2022 using the Scopus, Medline/PubMed and Web of Science databases. Results: Seventeen studies have been included with a total of 783,672 patients (32,634 treated with PTGBD vs. 4663 who underwent laparoscopic cholecystectomy, 343 who had open cholecystectomy and 746,032 who had some form of cholecystectomy, but without laparoscopic or open approach being specified). An analysis of the results shows that PTGBD, despite being less invasive, is not associated with lower morbidity with respect to EC (RR 0.77 95% CI [0.44 to 1.34]; I² = 99%; p = 0.36). A lower postoperative mortality was reported in patients who underwent EC (2.37%) with respect to the PTGBD group (13.78%) (RR 4.21; 95% CI [2.69 to 6.58]; p < 0.00001); furthermore, the risk of hospital readmission for biliary complications (RR 2.19 95% CI [1.72 to 2.79]; I² = 48%; p < 0.00001) and hospital stay (MD 4.29 95% CI [2.40 to 6.19]; p < 0.00001) were lower in the EC group. Conclusions: In our systematic review, the majority of studies have very low-quality evidence and more RCTs are needed; furthermore, PTGBD is inferior in the treatment of AC in high-risk patients. The definition of high-risk patients is important in interpreting the results, but the methods of assessment and definitions differ between studies. The results of our systematic review and meta-analysis failed to demonstrate any advantage of using PTGBD over ER as a definitive treatment of AC in critically ill patients, which suggests that EC should be considered as the treatment of choice even in very high-risk patients. Most likely, the inferiority of PTGBD versus early LC for high-risk patients is related to an association of various patient-side factor conditions and the severity of acute cholecystitis.

Background: The management of high-surgical-risk patients with moderate to severe acute cholecystitis is challenging in clinical practice. Early laparoscopic cholecystectomy is considered the gold standard for patients who do not respond to conservative treatment. However, for those unfit for surgery due to high risk, alternative treatment options, such as percutaneous cholecystostomy (PC), are available. There are no clear guidelines regarding the management of patients following PC. The primary aim of this study was to propose indications for PC in high-surgical-risk patients with acute cholecystitis and to establish management strategies for gallbladder drainage, either as a bridge to surgery or as a definitive treatment, according to available literature. Materials and methods: After a targeted literature review, International and Italian experts in the field from the Italian Society of Research in Surgery (SIRC) and the Italian Society of Emergency Surgery and Trauma (SICUT) were consulted to provide their evidence-based opinions on the topic. Statements were proposed during subsequent rounds using the Delphi methodology. Ten statements were provided, and the final agreement is presented in this study. Results: Patients with moderate acute cholecystitis, a Charlson Comorbidity Index (CCI) ≥ 6, and American Society of Anesthesiologists-Performance Status (ASA-PS) ≥ 3 who fail conservative treatment should undergo laparoscopic cholecystectomy as the first-line approach. For those with severe acute cholecystitis at high-surgical risk, percutaneous cholecystostomy is recommended to relieve symptoms within 24–48 hours. Once the infection is controlled, we should assess which patients may be candidates for interval laparoscopic cholecystectomy. For patients selected for surgery, laparoscopic cholecystectomy is recommended at least six weeks after PC placement. In patients not suitable for surgery, such as those with CCI ≥ 6 and ASA-PS ≥ 4, percutaneous cholecystostomy should remain in place for at least three weeks, after which, following radiographic confirmation of biliary tree patency, the tube may be removed. Conclusions: This consensus, developed through a multidisciplinary collaboration of interventional radiologists, gastroenterologists, and surgeons, provides a clear and practical guide for managing high-risk surgical patients with acute cholecystitis.

Background: This systematic umbrella review aims to investigate and provide an analysis of guidelines regarding the treatment of diverticular abscesses. Material and methods: A systematic literature search was performed using the Cochrane Overviews of Reviews model and the ‘Clinical Practice Guidelines’; at the end of initial search, only 12 guidelines were included in this analysis. The quality of the guidelines was assessed by adopting the “Appraisal of Guidelines for Research and Evaluation II” (AGREE II). The comparative analysis of these guidelines has highlighted the presence of some differences regarding the recommendations on the treatment of diverticular abscesses. In particular, there are some controversies about the diameter of abscess to be used in order to decide between medical treatment and percutaneous drainage. Different guidelines propose different abscess diameter cutoffs, such as 3 cm, 4–5 cm, or 4 cm, for distinguishing between small and large abscesses. Conclusions: Currently, different scientific societies recommend that diverticular abscesses with diameters larger than 3 cm should be considered for percutaneous drainage whereas abscesses with diameters smaller than 3 cm could be appropriately treated by medical therapy with antibiotics; only a few guidelines suggest the use of percutaneous drainage for abscesses with a diameter greater than 4 cm. The differences among guidelines are the consequence of the different selection of scientific evidence. In conclusion, our evaluation has revealed the importance of seeking new scientific evidence with higher quality to either confirm, reinforce or potentially weaken the existing recommendations from different societies.

Background and Objectives: Trauma, particularly uncontrolled bleeding, is a major cause of death. Recent evidence-based guidelines recommend the use of a tourniquet when life-threating limb bleeding cannot be controlled with direct pressure. Prehospital hemorrhage management, according to the XABCDE protocol, emphasizes the critical role of tourniquets in controlling massive bleeding. The aim of this systematic review and meta-analysis was to summarize data from the available scientific literature on the effectiveness of prehospital tourniquet use for extremity bleeding. Materials and Methods: A systematic review and meta-analysis was performed between March 2022 and March 2024, adhering to PRISMA guidelines, to determine whether prehospital tourniquets are clinically effective. The protocol was published on PROSPERO (ID number: CRD42023450373). Results: A comprehensive literature search yielded 925 articles and 11 studies meeting the inclusion criteria. The analysis showed a non-statistically significant reduction in mortality risk with tourniquet application (4.02% vs. 6.43%, RR 0.70, 95% CI 0.46–1.07). Analysis of outcomes of amputation of the traumatized limb indicated a statistically higher incidence of initial amputation in the tourniquet group (19.32% vs. 6.4%, RR 2.07, 95% CI 1.21–3.52), while delayed amputation showed no difference (9.39% vs. 3.66%, RR 0.93, 95% CI 0.42–2.07). Tourniquet use demonstrated a non-significant reduction in the number of blood components transfused (MD = −0.65; 95% CI −5.23 to 3.93 for pRBC, MD = −0.55; 95% CI −4.06 to 2.97 for plasma). Conclusions: Despite increasing use in civilian settings, this systematic review and meta-analysis showed no significant reduction in mortality or blood product use associated with prehospital tourniquet use. Further research, including high-quality randomized controlled trials, is required, as well as awareness and education campaigns relating to proper tourniquet use in the prehospital setting.

Background: Knowledge of vascular anatomy and its possible variations is essential for performing embolization or revascularization procedures and complex surgery in the pelvis. The obturator artery (OA) is a branch of the anterior division of the internal iliac artery (IIA), and it has the highest frequency of variation among branches of the internal iliac artery. Possible anomalies of the origin of the obturator artery (OA) should be known when performing pelvic and groin surgery, where its control or ligation may be required. The purpose of this systematic review and meta-analysis, based on Sanudo’s classification, is to analyze the origin of the obturator artery (OA) and its variants. Methods: Thirteen articles published between 1952 and 2020 were included. Results: The obturator artery (OA) was present in almost all cases (99.8%): the pooled prevalence estimate for the origin from the IIA axis was 77.7% (95% CI 71.8–83.1%) vs. 22.3% (95% CI 16.9–28.2%) for the origin from EIA axis. In most cases, the obturator artery (OA) originated from the anterior division trunk of the internal iliac artery (IIA) (61.6%). Conclusions: Performing preoperative radiological examination to determine the pelvic vascular pattern and having the awareness to evaluate possible changes in the obturator artery can reduce the risk of iatrogenic injury and complications.

Background: Electric motorized rental scooters (ES) were introduced in Italy in 2019 as an alternative form of urban transportation, aiming to reduce traffic congestion and air pollution. As their popularity has grown, a parallel increase in ES-related injuries has been observed. This study aims to investigate the types and patterns of ES-related injuries and to identify potentially modifiable risk factors. Methods: We conducted a retrospective analysis of all consecutive patients admitted to the Emergency Department of Policlinico Umberto I in Rome between January 2020 and December 2022 following ES-related trauma. Collected data included demographics, injury mechanisms and types, helmet use, Injury Severity Score (ISS), blood alcohol levels, and patient outcomes. Results: A total of 411 individuals presented to the Emergency Department due to ES-related injuries, either as riders or pedestrians. The mean age was 31 years (range: 2–93); 38 patients (9%) were under 18 years of age. Fifty-six accidents (14%) occurred during work-related commutes. Only three riders (0.7%) wore helmets, and nine patients (2%) had blood alcohol levels > 0.50 g/L. Cranial injuries (134 cases, 32%) and upper limb fractures (93 cases, 23%) were the most frequently reported serious injuries. The mean ISS was 4.5; 17 patients (4%) had an ISS ≥ 16. A total of 270 orthopedic injuries and 118 (29%) maxillofacial injuries were documented. Head trauma was reported in 115 patients (28%), with 19 cases classified as severe traumatic brain injuries. Twenty-three patients (5.5%) were hospitalized, three (0.7%) required intensive care, and one patient (0.2%) died. Conclusions: ES-related injuries are becoming increasingly common and present a significant public health concern. A nationwide effort is warranted to improve rider safety through mandatory helmet use, protective equipment, alcohol consumption control, and stricter enforcement of speed regulations.
