    Abstract In 2008 Uranues published the results of a questionnaire sent to experts across 27 European countries on the assessment of attitudes toward acute care surgery and he concluded that no unified system of acute care surgery in Europe was yet developed due to different approaches to the surgical critical patient and that, with exception of some dedicated centres, the intra-hospital resources were not dedicated to acute care surgery patients with consequent negative impact on ideal treatment both in the elective and acute patients (1). The problem in most of European countries is still the same: who is the best surgeon to deal with these patients with an acute surgical condition? The era of the "omnipotent general surgeon" is to an end and in order to improve quality in specific areas many institutions dedicate most of their economic resources to highly specialized surgical units; nowadays young committed surgeons are therefore attracted by the so-called "organ specific surgery" and take care of emergency surgery and trauma cases just because of a contractual obligation. The lack of subspecialty in trauma and acute care and the lack of interest in the treatment of such complex surgical and trauma cases did not give impetus to the development of clinical standards or professional accreditations guidelines causing a perfect storm with consequent provided care that is less than optimal.

    Abstract Background: Ideal visualization of fluorescent cholangiography during laparoscopic cholecystectomy is when maximum fluorescence into biliary ducts and absent signal into liver parenchyma, defined as "signal to background ratio" (SBR), is obtained. Such condition is mainly dependent by indocyanine green (ICG) dose and timing. The aim of this study was to identify the ideal ICG dose to obtain the best possible intraoperative visualization of the extra-hepatic biliary tree.
    Methods: The first part of the study was used to define a range of small weight-based ICG dosages using the mathematical function bisection method. During the second part of the study, the midpoint dose of the identified range, was tested in 50 consecutive cholecystectomies using a laser-based fluorescence laparoscopic camera (Synergy
    Results: Fourteen patients were included in the first part of the study and ICG dose between 0.01191406 and 0.0119873 mg/kg was identified. The second part confirmed previous results after testing the dosage equal to 0.0119 mg/kg (midpoint of the defined range) in 50 consecutive cholecystectomies. Cystic duct was identified in 66 and 100% of cases before and after dissection of Calot's triangle respectively. On the other hand, common bile duct was identified in 82 and 92% before and after dissection respectively. Subjective and objective SBRs confirmed the benefit of the identified ICG dose.
    Conclusion: ICG dose calculated by 0.0119 mg/kg administered one hour before surgery allows an ideal intraoperative visualization of the extra-hepatic biliary tree.

    Abstract Background: Open Abdomen (OA) is gaining popularity in damage control surgery (DCS) but there is not an absolute prognostic score to identify patients that may benefit from it. Our study investigates the correlation between the clinical frailty scale score (CFSS) and postoperative morbidity and mortality in patients undergoing OA.
    Methods: Patients ≥65 yo undergoing OA in two referral centres between 2015 and 2020 were included and stratified according to CFSS in non-frail (NF), frail (F) and highly-frail (HF). The primary endpoint was 30-day mortality. Secondary endpoints were postoperative morbidity and 1- year survival.
    Results: One hundred and thirty-six patients were included: 35 NF (25.7%), 56 F (41.2%), 45 HF (33.1%). Average age 76.8. The 73.5% of cases were non-traumatic diseases with no difference in preoperative characteristics. 95 (71.4%) had one complication, 26 NF (74.3%), 34 F (63.2%), 35 HF (77.8%) (P=0.301) and 59.4% had a complication with a CD≥3, 57.1% NF, 56.6% F and 64.4 HF. The 30-day mortality was 32.4%, higher in HF (46.7%) and F (30.4%) compared to NF (17.1%, P=0.018). The Overall 1-year survival was 41% (SE ±4) with statistically significant difference between HF vs. NF and HF vs. F (P=0.009 and P=0.029, respectively). In the univariate analysis, the only significant prognostic factor impacting mortality was CFSS, with HF having an HR of 1.948 (95% CI 1.097-3.460, P=0.023).
    Conclusions: When OA is a surgical option, frail patients should not be precluded, while HF should be carefully evaluated. The CFSS might be a good prognostic score for patients that may safely benefit from OA.

    Abstract We present the case of a 36-year-old primigravida who gave birth to a 3200 g baby by vacuum-assisted (Kiwi OmniCup™) operative vaginal delivery with mediolateral episiotomy. A "y"-shaped perineal tear with a grade IIIC obstetric anal sphincter injury (OASI) was diagnosed and repaired. Two days after delivery, in the absence of suture dehiscence, she started experiencing complete anal incontinence. A decision was made in association with a proctologic surgeon for an early secondary repair. Before surgery, a Three-dimensional transperineal ultrasound (TPUS) was performed. The exam revealed a major defect of the external anal sphincter at the 11 o'clock position. This allowed for the reopening of only a circumscribed area of the perineal suture and repair of the sphincters using the end-to-end technique. The symptoms regressed completely, and follow-up TPUS demonstrated the gradual wound healing process. Anal incontinence, secondary to obstetric anal sphincter injury (OASI), has a severe negative impact on women's quality of life. TPUS is an effective method to detect sphincter defects and monitor the healing process. This report investigates the feasibility of identifying the sphincter tear in an incontinent puerperal patient without suture dehiscence in order to target early secondary repair while minimizing its extent. TPUS has proven a safe and effective tool to guide early secondary repair of symptomatic OASI complications while minimizing the invasiveness of the procedure. Multidisciplinary management is crucial to ensure the adequate standard of care.

    Abstract Acute cholecystitis (AC) is a very common disease in clinical practice. Laparoscopic cholecystectomy remains the gold standard treatment for AC, however due to aging population, the increased prevalence of multiple comorbidities and the extensive use of anticoagulants, surgical procedures may be too risky when dealing with patients in emergency settings. In these subsets of patients, a mini-invasive management may be an effective option, both as a definitive treatment or as bridge-to-surgery. In this paper, several non-operative treatments are described and their benefits and drawbacks are highlighted. Percutaneous gallbladder drainage (PT-GBD) is one of the most common and widespread techniques. It is easy to perform and has a good cost/benefit ratio. Endoscopic transpapillary gallbladder drainage (ETGBD) is a challenging procedure that is usually performed in high volume centers by expert endoscopists, and it has a specific indication for selected cases. EUS-guided drainage (EUS-GBD) is still not widely available, but it is an effective procedure that could have several advantages, especially in rate of reinterventions. All these treatment options should be considered together in a stepwise approach and addressed to patients after an accurate case-by-case evaluation in a multidisciplinary discussion. In this review, we provide a possible flowchart in order to optimize treatments, resource and provide to patients a tailored approach.
