BackgroundKnowledge about bacterascites is limited and management guidelines are based on small patient series. The purpose of this study was to add further insight into the clinical characteristics, microbiological findings, and prognosis of patients diagnosed with bacterascites.MethodsRetrospective analysis of patients with advanced chronic liver disease diagnosed with bacterascites and SBP between January 2003 and August 2016.ResultsIn this study, 123 patients were included with 142 episodes of bacterascites. The median MELD score was 20 and clinical symptoms of infection were present in 78%. Empiric antibiotic treatment was initiated in 68%. In 26 untreated patients undergoing repeated paracentesis, 42% were diagnosed with either ongoing bacterascites or SBP. The presence of signs or symptoms of infection was not an independent predictor for mortality or spontaneous resolution of infection. The 1‐month and 1‐year mortality rates of the 123 patients studied, were 32% and 60%, respectively; these results were in line with data pertaining to the prognosis of SBP.ConclusionsPatients with bacterascites and SBP are highly comparable with respect to severity of liver disease and overall prognosis. If left untreated, bacterascites is likely to persist or to evolve to SBP in a significant proportion of patients. The results of this study support current guidelines regarding the treatment of ascitic fluid infection, but could not confirm the prognostic relevance of symptomatic disease at the time of diagnosis. We suggest that the threshold to initiate antibiotic treatment, in particular in cases with severely advanced liver disease, should be low.
Background: One of the cornerstones of palliative treatment for unresectable perihilar cholangiocarcinoma is biliary stent placement in order to restore biliary drainage. In this review, the potential added value of RFA with stent placement in comparison to stent placement alone in patients with unresectable perihilar cholangiocarcinoma is analyzed. Methods: We performed a comprehensive online search for relevant articles in November 2021 (PROSPERO ID: CRD42021288180). The primary endpoint was difference in overall survival. Secondary endpoints included overall survival, stent patency and complications. Only studies comparing survival after RFA + stent placement with stent placement alone were included in the meta-analysis. Non-comparative studies or comparative studies describing stent patency only were included in the systematic review. Results: A total of nine studies, including 217 patients with pCCA who underwent RFA + stent placement and 294 patients who underwent stent-only treatment, met the inclusion criteria for the primary endpoint analysis. Direct comparison between the two treatment groups showed a significantly longer overall survival for RFA + stent treatment, with a pooled HR of 0.65 [95% CI, 0.50–0.84, I2 = 38%]. When all eligible studies were included, RFA + stent treatment revealed an overall survival of 9.5 months [95% CI, 6.3–12.6], whereas survival for stent-only treatment was 7.0 months [95% CI, 5.7–8.2]. Due to the heterogeneity of the data, no pooled data analysis could be performed on stent patency or complications. Conclusions: RFA + stent placement displays promising potential to prolong survival. However, further research incorporating confounding factors like use of palliative chemotherapy is necessary in order to validate these findings.
Introduction: Confirming the diagnosis, invasiveness, and extent of disease of intraductal papillary mucinous neoplasms (IPMN) of the pancreas is challenging. The aim of this study is to summarize the literature on the efficacy and safety of peroral pancreatoscopy (POP) in the diagnosis of IPMN, including the impact of pre- and intraoperative POP on the management of IPMN. Methods: The EMBASE, Medline Ovid, Web of Science, Cochrane CENTRAL and Google Scholar databases were systematically searched for articles. Eligible articles investigated cohorts of patients who underwent POP for (suspected) IPMN. Results: Twenty-five articles were identified and included in this review. Twenty-two articles reported on the diagnostic yield of POP in IPMN and eleven articles reported on the effect of pre- or intraoperative POP on clinical decision making. Cannulation, observation rates and overall diagnostic accuracy were high across all studies. Frequently reported visual characteristics of IPMN were intraductal fish-egg-like lesions, hypervascularity, and granular mucosa. Overall, the adverse event rate was 12%, primarily consisting of post-ERCP pancreatitis with a pooled rate of 10%, most of mild severity. Regarding the impact of POP on clinical decision making, in 13-62% of patients POP findings altered the surgical approach. Conclusion: POP is technically successful in the vast majority of patients with (suspected) IPMN, has a considerably high diagnostic accuracy, but an adverse event rate of 12%. Data on intraoperative pancreatoscopy is scarce, but small studies suggest its use can alter surgical management. Future studies are needed to better define the role of POP in the diagnostic work-up of IPMN.
Background and study aims The safety of transpapillary biliary drainage by stent placement through endoscopic retrograde cholangiography (ERC) may be compromised by the occurrence of stent migration-induced perforation of the duodenal wall (SMDP). We aimed to assess the prevalence rate, risk factors and clinical course of SMDP. Patients and methods This retrospective cohort study included all patients who underwent an ERC with biliary plastic stent placement, between January 2014 and December 2018. Patients with an SMDP were identified from our endoscopy complication registry. Results 1227 patients underwent an ERC, of whom 629 patients (51 %) with biliary plastic stent placement; in 304 patients (25 %) stents were placed for perihilar strictures. Thirteen patients with SMDP were identified. The prevalence was 2.1 % for patients with biliary plastic stent placement and 4.3 % for patients stented for a perihilar stricture. All SMDPs occurred in patients with a perihilar stricture and with stents ≥ 12 cm (range 12–20 cm). Another potential risk factor was stent insertion into the left liver lobe, which was present in 10 of 13 patients. In 10 of 13 patients, SMDP was clinically suspected. Three of 13 patients were asymptomatic and diagnosed at elective stent retrieval. Eight patients could be endoscopically treated with an over-the-scope clip. Four patients died due to abdominal sepsis despite repeated interventions. Conclusion SMDP is a rare but potentially life-threatening complication of ERC after transpapillary drainage for perihilar biliary strictures. Stents ≥ 12 cm and stent insertion into the left liver lobe may be associated risk factors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
