RESUMEN
The present study investigated the improvement in the diagnosis of invasive pulmonary aspergillosis (IPA) adding a molecular test on bronchoalveolar lavage (BAL) to the routine diagnostic approach including microscopy, culture and galactomannan (GM) immunoassay. A total of 133 BAL samples were retrospectively tested for the Aspergillus DNA: 112 samples were from immunocompromised patients at risk of invasive fungal infection and 21 were from patients not at risk and without clinical evidence of IPA. The latter samples were used to identify the cut-off of positivity for the molecular test. Applying the cut-off quantity of 50 copies/reaction, the PCR test had 90% sensitivity and 97% specificity and resulted the most sensitive, specific and accurate among those evaluated. The statistical analysis showed that the probability that a patient is not affected by IPA is 99% when the three tests (PCR, GM and culture) are concordantly negative.

Major concerns about donor morbidity and mortality still limit the use of living donor liver transplantation (LDLT) to overcome the organ shortage. The present study assessed donor safety in LDLT in Italy reporting donor postoperative outcomes in 246 living donation procedures performed by 7 transplant centers. Outcomes were evaluated over 2 time periods using the validated Clavien 5-tier grading system, and several clinical variables were analyzed to determine the risk factors for donor morbidity. Different grafts were obtained from the 246 donor procedures (220 right lobe, 10 left lobe, and 16 left lateral segments). The median follow-up after donation was 112 months. There was no donor mortality. One or more complications occurred in 82 (33.3%) donors, and 3 of them had intraoperative complications (1.2%). Regardless of graft type, the rate of major complications (grade ≥ 3) was 12.6% (31/246). The overall donor morbidity and the rate of major complications did not differ significantly over time: 26 (10.6%) donors required hospital readmission throughout the follow-up period, whereas 5 (2.0%) donors required reoperation. Prolonged operative time (>400 minutes), intraoperative hypotension (systolic < 100 mm Hg), vascular abnormalities, and intraoperative blood loss (>300 mL) were multivariate risk factors for postoperative donor complications. In conclusion, from the standpoint of living donor surgery, a meticulous and well-standardized technique that reduces operative time and prevents blood loss and intraoperative hypotension may reduce the incidence of donor complications. Transparency in reporting results after LDLT is mandatory, and we should continue to strive for zero donor mortality. Liver Transplantation 23 184-193 2017 AASLD.

BACKGROUND AND AIMS: Because a traditional rendezvous (RV) technique implies stretching of the papilla, possibly leading to post-ERCP pancreatitis, an alternative duodenal RV technique was evaluated. The aim was to assess the effectiveness, safety, and amount of time spent performing duodenal RV versus traditional RV cannulation in orthotopic liver transplantation patients with a T-tube. METHODS: We retrospectively reviewed data from a prospective ERCP database held by our university hospital. Twenty patients with a T-tube who had undergone ERCP for biliary adverse events after orthotopic liver transplantation were included. The successful cannulation rate, the amount of time spent performing cannulation, the post-ERCP pancreatitis rate, and hyperamylasemia 24 hours after the procedure were recorded. RESULTS: Successful cannulation was achieved by the duodenal RV technique in 9 of 10 patients (90%), taking 146 seconds (interquartile range 63-341 seconds) with a short learning curve effect. An unsuccessful duodenal RV procedure occurred because of the angulation of the hydrophilic tip of the guidewire while crossing the papilla, thus preventing cannulation. Successful cannulation was achieved by the traditional RV technique in all cases (N = 11), including the failed duodenal RV technique, taking 374 seconds (interquartile range 320-410 seconds) (P < .05 vs duodenal RV). However, no post-ERCP pancreatitis occurred after using the duodenal RV technique compared with 2 episodes of mild pancreatitis after using the traditional RV technique. Twenty-four hours after the procedure, the median amylasemia level was 84 IU/L (interquartile range 49-105 IU/L) and 265 IU/L (interquartile range 73-2945 IU/L) for the duodenal versus traditional RV techniques, respectively (P = not significant). CONCLUSIONS: In patients with a T-tube after liver transplantation, the duodenal RV technique was not associated with post-ERCP pancreatitis, presumably because of the reduction of stress on the major papilla. Cannulation by using the duodenal RV technique was faster compared with the traditional RV technique. These preliminary data point out the use of the duodenal RV technique as the first option to choose in case of failed cannulation before attempting the traditional RV technique.

OBJECTIVES: Searching for retained bullets has always been crucial in war surgery. Aim of this paper is to briefly outline the history of retained bullet identification methods before X-rays discovery and describe the proliferation of the most significant methods of foreign body localization during WWI. METHODS: Coeval medical journals, reference textbooks, dedicated manuals and documents have been searched and compared in multiple archives and on the internet. RESULTS: Before radiologic era, probing the wound was the only way to detect the bullet and minimize the need of a large surgical incision (anaesthesia was walking its first tentative steps and antisepsis still to be conceived). Nelaton's probe, specifically designed to detect General Garibaldi's retained projectile, gained popularity. Application of electricity provided further rudimental aids to find retained metals. X-rays discovery made bullet detection easy, but exact localization to guide removal was still difficult. Hundreds of imaginative X-Ray methods for localizing bullets and splinters more precisely in the countless complex wounds flourished during the Great War. Axis intersection, geometric reconstruction and anatomical criteria guided localization. Complex procedures and rudimental localizers to simplify calculations, and a number of compasses and magnetic or electric devices to aid surgical removal were developed, and are here outlined. Intermittent radiology assessment or combined radiology and surgery procedures started to play a role. CONCLUSIONS: All these methods and tools are the ancestors of modern navigation systems, ensured by images digitalization and miniaturization technologies. KEY WORDS: Foreign bodies, Mobile Health Units, Radiology, X-Rays, World War I, Wounds and injuries.

PURPOSE: Treatment of rectocele associated with prolapsed hemorrhoids is a debated topic. Transanal stapling achieved good midterm results in patients with symptoms of obstructed defecation, nevertheless a number of severe complications have been reported. The aim of this study was to evaluate the safety and efficacy of a new endorectal manual technique in patients with obstructed defecation due to the combination of muco-hemorrhoidal prolapse and rectocele. METHODS: Patients enrolled after preoperative obstructed defecation syndrome (ODS) score, defecography and anoscopy were submitted to the novel Mucopexy-Recto Anal Lifting (MuRAL) combined with a modified Block procedure, and followed up by independent observers with digital exploration 3 weeks postoperatively, and digital exploration plus anoscopy at 3, 6, and 12 months. Operative time, hospital stay, numerating rating scale (NRS), ODS, satisfaction scores, and recurrence rate were recorded. RESULTS: Mean operative time was 35.7 minutes. Fifty-six patients completed 1-year follow-up: 7.1% had acute urinary retention, NRS score was < 3 from the third postoperative day, mean time of daily activity resumption was 12 days, none had persistent fecal urgency, 82% declared excellent/good satisfaction score, significant improvement of 6- and 12-month ODS score, no recurrence of rectocele, and 7.1% recurrence of prolapsed hemorrhoids were observed. CONCLUSION: MuRAL associated with modified Block technique gave no severe complications and resulted in a safe and effective approach to symptomatic rectocele associated with muco-rectal prolapse. Further randomized studies, larger series, and longer follow-up are needed.
RESUMEN
BACKGROUND: Posttransplant combined lamivudine (LAM) and immunoglobulin (HBIg) prophylaxis is the gold standard in the case of single hepatitis B virus (HBV), but is still not recommended in the case of patients coinfected with hepatitis delta virus (HDV). METHODS: We compared two consecutive groups of chronic HDV carriers who survived >6 months after liver transplantation of the risk of recurrence, survival and HBIg requirements: 21 received passive prophylaxis (HBIg group) and 25 were treated with combined prophylaxis (LAM+HBIg group). The immunoprophylaxis schedule was the same in both groups: intramuscular HBIg targeted to maintain anti-HBs levels of >500 IU/L during the first 6 posttransplant months and >200 IU/L thereafter. RESULTS: The mean length of follow-up in the two groups was significantly different (133 vs. 40 months; P<0.001). None of the patients in either group developed recurrent hepatitis, and the 3-year actuarial survival rate was 100% in both groups. During the first 6 months, HBIg requirement was 38% lower in the LAM+HBIg group although similar anti-HBs target levels were maintained, leading to significantly lower costs (5,000 Euros in the first year and 500 Euros in the second). CONCLUSIONS: This is the first study of large and homogeneous cohort of long-term HDV coinfected liver transplant survivors showing the absence of HBV recurrence under combined prophylaxis. Although retrospective, our results suggest that combined anti-HBV prophylaxis should also be preferred to single immunoprophylaxis in patients with HDV coinfection because it allows significant cost savings in the first two posttransplant years.
