    Abstract Background: Anastomotic leakage (AL) as a result of creation of a colorectal/anal anastomosis still represents a frequent complication of colorectal surgery, with short- and long-term consequences on postoperative morbidity, quality of life and oncological outcomes. However, early diagnosis of AL may result in improved outcomes. The aims of this study were to evaluate the diagnostic accuracy of water-soluble contrast enema (WSCE), contrast enema computed tomography (CECT) and endoscopy in identifying AL and to identify the diagnostic procedure that is most accurate.
    Methods: A systematic review and meta-analysis of 19 studies accounting for a total of 25 tests reporting diagnostic accuracy estimates was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses of Diagnostic Test Accuracy Studies (PRISMA-DTA) guidelines up to June 2021. For the diagnostic tests we evaluated the pooled estimates and conducted pairwise comparisons.
    Results: For WSCE, the pooled sensitivity was 0.50, the pooled specificity was 0.99 and the area under the curve (AUC) was 0.91. For endoscopy, the pooled sensitivity was 0.69, specificity was 1.00 and AUC was 0.99. The pooled sensitivity and specificity for CECT were 0.89 and 1.00, respectively; the AUC was 0.99. The comparison between CECT and WSCE highlighted a significantly greater sensitivity (p = 0.04) for CECT, whereas no difference was found for specificity. Compared with CECT, endoscopy was not significantly more accurate in terms of either sensitivity or specificity. Endoscopy was found to be significantly more specific than WSCE (p = 0.031) but no difference was found for sensitivity.
    Conclusion: Water-soluble contrast enema, endoscopy and CECT have an elevated diagnostic accuracy. However, WSCE is less accurate than either endoscopy or CECT. Although greater sensitivity was demonstrated for CECT compared with endoscopy, this was not significant.

    Abstract Anal post-operative pain is one of the principal issues of surgical treatment of hemorrhoids and remains a distressing problem, for patients and physicians. Recent studies have concluded that appropriate postoperative pain management leads to higher patient satisfaction, earlier mobilization, fewer drug complications, eliminated adverse events, faster recovery, and decreased health care cost. However, despite advances in pain medicine, postoperative pain control remains problematic and remains an important unresolved issue that causes expense and patient dissatisfaction. Therefore, this situation calls for multi-modal pain management, choosing medication, dosing regimens and route of administration in an individualized way to optimize efficacy and minimize adverse effects. Multiple approaches, including pharmacological and surgical interventions, have been used to manage pain after hemorrhoidal surgery. Our aim was to check the latest instruments and strategies available in literature designed to find practical solutions to this challenging problem.

    Abstract Background: Huge (>10 cm) hepatocellular carcinoma is burdened by elevated mortality due to its peculiar characteristics and delayed diagnosis. Liver resection is considered the gold standard although survival is poor. Recently, some different strategies have been evaluated to improve results in tumor recurrence and survival. The aim of this research is to identify which strategy offers the best results in terms of overall survival for resectable huge hepatocellular carcinoma.
    Methods: A systematic review and network meta-analysis of 13 studies was conducted from PubMed, Embase, Scopus, Cochrane Library, and Web of Science databases including research comparing two or more treatments to manage huge hepatocellular carcinoma. Results were synthesized through forest plots and risk of bias assessed with the CINeMA framework as recommended.
    Results: The association of liver resection and transcatheter arterial chemoembolization confers a significant improvement in survival compared to liver resection alone (HR: 0.55) while transcatheter arterial chemoembolization, radioembolization, and ethanol ablation alone were associated to decreased overall survival. Within-study bias, indirectness and incoherence were the domains mainly affected by concerns in risk of bias analysis.
    Conclusion: Multimodal treatment including liver resection and transcatheter arterial chemoembolization increases survival in patients with resectable huge hepatocellular carcinoma.

    Abstract Purpose: An increasing Pnumber of individuals with obesity over the age of 60 years require bariatric surgery to treat obesity and its related medical problems. Sleeve gastrectomy and Roux-en-Y gastric bypass have already proven their efficacy in this population, but literature lacks reports of long-term results. The aim of this study is to compare long-term results of sleeve gastrectomy and Roux-en-Y gastric bypass in individuals older than 60 years old.
    Materials and methods: This is a single-center, retrospective, comparative study of 204 patients undergoing either sleeve gastrectomy (123, 60.3%) or Roux-en-Y gastric bypass (81, 39.7%) for morbid obesity with a mean follow-up of 44.5 ± 19.1 months and 54.6 ± 17.9 months, respectively.
    Results: Total weight loss was significantly increased for patients who underwent Roux-en-Y gastric bypass compared to sleeve gastrectomy from 12 to 48 months after surgery, while no significant difference was found after 60 (30.39% vs. 27.63%) and 72 (27.36% vs. 23.61%) months. Roux-en-Y gastric bypass was associated to a significant increased rate of early postoperative complications (22.2% vs. 4%; p < 0.0001), but no difference was found concerning late postoperative morbidity (6.2% vs. 1.6%). Both procedures were effective in obesity related medical problems.
    Conclusion: Roux-en-Y gastric bypass confers an increased weight loss than sleeve gastrectomy in patients over the age of 60 in the mid-term, but it is associated with more early postoperative complications. Sleeve gastrectomy can be considered a valid alternative as long-term weight loss results are superposable to those ensured by Roux-en-Y gastric bypass.

    Abstract In the present study, we analyzed the safety and efficacy of non-intubated video-assisted thoracoscopy (NI-VATS) for the diagnosis and palliation of malignant pleural effusion in the elderly population using erector-spinae plane block (ESPB) as single loco-regional anesthesia. From January 2016 to December 2020 a consecutive series of 158 patients who underwent surgery for malignant pleural effusion was analyzed. Of these, 20 patients were operated using ESPB NI-VATS, while 138 were operated under general anesthesia (GA). After propensity score matching, the NI-VATS population was older (81 vs. 76 years p 0.006), and had more severe pre-existing comorbidities, evaluated using Charlson Comorbidity Index (p = 0.029) and ASA score (p < 0.001). GA and NI-VATS patients did not differ in terms of postoperative opioid consumption, complication rate and postoperative hospitalization. Both short- and long-term efficacy of talc poudrage was equal in the two populations. The overall length of stay in the operative room was significantly shorter for the NI-VATS than for the GA-VATS group (67.5 vs. 105 min, p < 0.001), and operative time significantly differed in the two groups (35 vs. 47.5 min, respectively, p < 0.001). ESPB NI-VATS can be a safe and effective option for the diagnosis and palliation of malignant pleural effusion for elderly and frail patients.

    Abstract Aim: Graciloplasty (GP) is indicated in the case of recurrent rectovaginal fistula (RVF) after failure of previous local treatments. The aim of this study was to assess risk factors for GP failure performed for RVF.
    Methods: This is a retrospective study based on a prospective database on GP, coming from two expert centres.
    Results: Sixty-one patients undergoing a first GP for RVF (n = 51) or ileal-vaginal fistula after ileal pouch anal anastomosis (n = 10), with a mean age of 42 years (range 24-72), were analysed. After a mean follow-up of 56 ± 48 months (range 1-183), failure of GP (considered as persistent stoma and/or clinical RVF) was noted in 24/61 patients (39%). The failure rate was 43% (13/30) in the case of Crohn's disease, 38% (3/8) in the case of ileal-vaginal fistula after ileal pouch anal anastomosis for ulcerative colitis, 30% (3/10) in the case of obstetrical RVF, 33% (1/3) in the case of post radiotherapy RVF and 40% (4/10) for other causes (not significant). Two risk factors for failure of GP were found on univariate analysis: (1) absence of postoperative antibiotic prophylaxis-only 3/24 (13%) patients with failure of GP received postoperative antibiotic prophylaxis versus 18/37 (49%) patients with success of GP (P = 0.0053); (2) postoperative perineal infection-11/23 (48%) with failure of GP developed postoperative perineal infection versus only 4/37 (10%) patients with success of GP (P = 0.0021).
    Conclusions: Failure of GP for RVF is observed in approximately 40% of the patients whatever the aetiology of the fistula. A reduced failure rate was associated with systematic postoperative antibiotic prophylaxis.

    Abstract Background: Roux-en-Y gastric bypass (RYGB) is currently one of the most performed bariatric procedures and it is associated with rapid weight loss. However, weight loss failure and weight regain after RYGB occurs in approximately 30% and 3−5% of patients, respectively, and represent a serious issue. RYGB pouch resizing is a surgical option that may be offered to selected patients with RYGB failure. The aim of this study is to assess long-term results of pouch resizing for RYGB failure. Materials and Methods: From February 2009 to November 2011, 20 consecutive patients underwent gastric pouch resizing for RYGB failure in our tertiary bariatric center. The primary outcome was the rate of failure (%EWL < 50% with at least one metabolic comorbidity) after at least 10 years from pouch resizing. Gastroesophageal Reflux Disease (GERD) was also assessed. Results: Twenty patients (18 women (90%)) were included and seventeen (85%) joined the study. The failure rate of pouch resizing was 47%. Mean %EWL and mean BMI were 47%, and 35.1 kg/m2, respectively. Some of the persistent co-morbidities further improved or resolved after pouch resizing. Seven patients (41%) presented GERD requiring daily PPI with a significantly lower GERD-HQRL questionnaire score after pouch resizing (p < 0.001). Conclusion: Pouch resizing after RYGB results in a failure rate of 47% at the 10-year follow-up while the resolution of comorbidities is maintained over time despite a significant weight regain.

    Abstract Since the Fukushima Daiichi Nuclear Power Plant accident in March 2011, the technology available for unmanned aerial vehicles (UAVs) for radiation monitoring has improved greatly. Remote access to radiation-contaminated areas not only eliminates unnecessary exposure of civilians or military personnel, but also allows workers to explore inaccessible places. Hazardous levels of radioactive contamination can be expected as a result of accidents in the nuclear power industry or as a result of the intentional release of radioactive materials for terrorist purposes (dirty bombs, building contamination, etc.). The possibility to detect, identify, and characterize radiation and nuclear material using mobile and remote sensing platforms is a common requirement in the radiation sensing community. The technology has applications in homeland security and law enforcement, customs and border protection, nuclear power plant safety and security, nuclear waste monitoring, environmental recovery, and the military. In this work, the authors have developed, implemented, and characterized a gamma-ray detection and spectroscopy system capable of operating on a UAV. The system was mainly developed using open-source software and affordable hardware components to reduce development and maintenance costs and provide satisfactory performance as a detection instrument. The designed platform can be used to perform mapping or localization tasks to improve the risk assessment process for first responders during the management of radiological and nuclear incidents. First, the design process of the system is described; the result of the characterization of the platform is then presented together with the use of the prototype installed on a UAV in an exercise simulating a radiological and nuclear contamination scenario.

    Abstract Background: Anatomical variations in the liver arterial supply are quite common and can affect the surgical strategy when performing a minimally invasive pancreaticoduodenectomy (MIPD). Their presence must be preemptively detected to avoid postoperative liver and biliary complications.
    Data sources: Following the PRISMA guidelines and the Cochrane protocol we conducted a systematic review on the management of an accessory or replaced right hepatic artery (RHA) arising from the superior mesenteric artery when performing an MIPD.
    Results: Five studies involving 118 patients were included. The most common reported management of the aberrant RHA was conservative (97.0%); however, patients undergoing aberrant RHA division without reconstruction did not develop liver or biliary complications. No differences in postoperative morbidity or long-term oncological related overall survival were reported in all the included studies when comparing MIPD in patients with standard anatomy to those with aberrant RHA.
    Conclusions: MIPD in patients with aberrant RHA is feasible without increase in morbidity and mortality. As preoperative strategy is crucial, we suggested planning an MIPD with an anomalous RHA focusing on preoperative vascular aberrancy assessment and different strategies to reduce the risk of liver ischemia.
