Acute cholecystitis (AC) is the most common biliary stone disease complication. While there is consensus regarding cholecystectomy for AC, gallbladder drainage is indicated in elderly or high-risk surgical patients. We systematically reviewed available evidence in the field of EUS-guided gallbladder drainage (EUS-GBD) for AC in high-risk surgical patients. The studies were classified according to their level of evidence (LE) according to the Oxford Centre for Evidence Based Medicine classification. Literature search retrieved 175 manuscripts; most of them were expert opinions (LE V, no. 53) or caseseries (LE IV, no. 29). There was no meta-analysis of RCT (LE Ia), while two randomized controlled trials (LE Ib) demonstrated that EUS-GBD was superior to percutaneous trans-hepatic-GBD (PT-GBD) regarding longterm outcomes (adverse events, recurrent cholecystitis, and reintervention). Several meta-analyses of cohort studies (LE IIa, no. 11) were designed to compare the three available drainage strategies (endoscopic, echoendoscopic and percutaneous) and to assess the pooled risk of adverse events. Comparison between surgery and EUS-GBD was done in a single retrospective study with a propensity score analysis (LE III). The outcomes of conversion from PT-GBD to EUS-GBD were covered by few retrospective studies (LE III). Several manuscripts (no. 69) were published on EUS-GBD as a rescue strategy in case of malignant biliary obstruction. The levels of evidence of EUS-GBD in the literature have evolved from initial descriptive studies to recent randomized controlled trials and meta-analysis of cohort studies. While several articles addressed the comparison among different techniques for GBD, in our opinion some topics and questions have not been adequately investigated. are still debated.

Background Health-related quality of life (HRQoL) impairment is often reported among COVID-19 ICU survivors, and little is known about their long-term outcomes. We evaluated the HRQoL trajectories between 3 months and 1 year after ICU discharge, the factors influencing these trajectories and the presence of clusters of HRQoL profiles in a population of COVID-19 patients who underwent invasive mechanical ventilation (IMV). Moreover, pathophysiological correlations of residual dyspnea were tested. Methods We followed up 178 survivors from 16 Italian ICUs up to one year after ICU discharge. HRQoL was investigated through the 15D instrument. Available pulmonary function tests (PFTs) and chest CT scans at 1 year were also collected. A linear mixed-effects model was adopted to identify factors associated with different HRQoL trajectories and a two-step cluster analysis was performed to identify HRQoL clusters. Results We found that HRQoL increased during the study period, especially for the significant increase of the physical dimensions, while the mental dimensions and dyspnea remained substantially unchanged. Four main 15D profiles were identified: full recovery (47.2%), bad recovery (5.1%) and two partial recovery clusters with mostly physical (9.6%) or mental (38.2%) dimensions affected. Gender, duration of IMV and number of comorbidities significantly influenced HRQoL trajectories. Persistent dyspnea was reported in 58.4% of patients, and weakly, but significantly, correlated with both DLCO and length of IMV. Conclusions HRQoL impairment is frequent 1 year after ICU discharge, and the lowest recovery is found in the mental dimensions. Persistent dyspnea is often reported and weakly correlated with PFTs alterations. Trial registration NCT04411459.

Background Recent evidences suggest that gallbladder drainage is the treatment of choice in elderly or high-risk surgical patients with acute cholecystitis (AC). Despite better outcomes compared to other approaches, endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) is burdened by high mortality. The aim of the study was to evaluate predictive factors for mortality in high-risk surgical patients who underwent EUS-GBD for AC. Methods A retrospective analysis of a prospectively maintained database was performed. Electrocautery-enhanced lumen-apposing metal stents were used; all recorded variables were evaluated as potential predictive factors for mortality. Results Thirty-four patients underwent EUS for suspected AC and 25 (44% male, age 78) were finally included. Technical, clinical success rate and adverse events rate were 92%, 88%, and 16%, respectively. 30-day and 1-year mortality were 12% and 32%. On univariate analysis, age-adjusted Charlson Comorbidity Index (CCI) (OR 20.8[4–68.2]), acute kidney injury (AKI) (OR 21.4[2.6–52.1]) and clinical success (OR 8.9[1.2–11.6]) were related to 30-day mortality. On multivariate analysis, CCI and AKI were independently related to long-term mortality. Kaplan–Meier curves showed an increased long-term mortality in patients with CCI > 6 (hazard ratio 7.6[1.7–34.6]) and AKI (hazard ratio 11.3[1.4–91.5]). Conclusions Severe comorbidities and AKI were independent predictive factors confirming of long-term mortality after EUS-GBD. Outcomes of EUS-GBD appear more influenced by patients’ conditions rather than by procedure success.

Background and Aims Pelvic fluid collections (PFCs) are frequent adverse events of abdominal surgery or inflammatory conditions. A percutaneous approach to deep PFCs could be challenging and result in a longer, painful recovery. The transvaginal approach has been considered easy but is limited by the difficulty of leaving a stent in place. The transrectal approach has been described, but issues related to fecal contamination were hypothesized. Data on EUS-guided transrectal drainage (EUS-TRD) with lumen-apposing metal stents (LAMSs) are few and suggest unsatisfactory outcomes. The aim of this study was to evaluate the safety and efficacy of EUS-TRD with LAMSs in patients with PFCs. Methods A retrospective analysis of a prospectively maintained database on therapeutic EUS was conducted. All EUS-TRD procedures were included. Results Five patients (2 male, age 44-89 years) were included. Four patients had postoperative PFCs, and 1 presented with a pelvic abscess complicating acute diverticulitis. Two of 5 had fecal diversion; the remaining 3 had unaltered large-bowel anatomy. One case had a concomitant abdominal collection, treated with percutaneous drainage in the same session. An electrocautery-enhanced LAMS delivery system (15 × 10 mm) was used in all cases. EUS-TRD was performed with the direct-puncture technique and lasted less than 10 minutes in 4 cases; in the remaining case, needle puncture and LAMS placement over a guidewire was required, and the procedure length was 14 minutes. The clinical success rate was 100%. LAMSs were removed after a median of 14 (range, 12-24) days. One patient reported partial proximal LAMS migration after 24 days (mild adverse event). No PFC recurrence was observed. Conclusion EUS-TRD with LAMSs is a safe and effective technique for treatment of PFCs. The use of 15- × 10-mm LAMSs allows rapid PFC resolution. EUS-TRD could be performed not only in patients with fecal diversion but also in cases of unaltered anatomy.
