RESUMO
Background and study aims Single-operator peroral cholangioscopy (SOC) has gained increasing attention in modern biliary and pancreatic therapy and diagnosis. This procedure has shown higher rates of infectious complications than conventional endoscopic retrograde cholangiopancreatography (ERCP); therefore, many guidelines recommend antibiotic prophylaxis (AP). However, whether AP administration decreases infectious or overall adverse events (AEs) has been little studied. We aimed to study whether AP affects post-procedure infectious or overall AEs in ERCP with SOC. Patients and methods We collected data from the Swedish Registry for Gallstone Surgery and ERCP (GallRiks). Of the 124,921 extracted ERCP procedures performed between 2008 and 2021, 1,605 included SOC and represented the study population. Exclusion criteria were incomplete 30-day follow-up, ongoing antibiotic use, and procedures with unspecified indication. Type and dose of antibiotics were not reported. Post-procedure infectious complications and AEs at 30-day follow-up were the main outcomes. Results AP was administered to 1,307 patients (81.4%). In this group, 3.4% of the patients had infectious complications compared with 3.7% in the non-AP group. The overall AE rates in the AP and non-AP groups were 14.6% and 15.2%, respectively. The incidence of cholangitis was 3.1% in the AP group and 3.4% in the non-AP group. Using multivariable analysis, both infectious complications (odds ratio [OR] 0.92, 95% confidence interval [CI] 0.54-1.57) and AEs (OR 0.87, 95% CI 0.65-1.16) remained unaffected by AP administration. Conclusions No reduction in infectious complication rates and AEs was seen with AP administration for SOC. The continued need for AP in SOC remains uncertain.
RESUMO
Background and Aim: Primary sclerosing cholangitis (PSC) is characterized by multiple strictures of the biliary tree. Patients with PSC frequently require repeated endoscopic retrograde cholangiopancreatography (ERCP) procedures. These procedures are encumbered by an increased incidence of infectious adverse events such as cholangitis. Evidence regarding whether antibiotic prophylaxis (AP) should be administered is sparse; however, prophylaxis is recommended. We aimed to determine whether AP affects the rate of postprocedural infectious and overall adverse events. Methods: We conducted a retrospective cohort study and extracted all ERCP procedures with indicated PSC performed between 1 January 2006 and 31 December 2019, which were registered in the Swedish Registry for Gallstone Surgery and ERCP (GallRiks). The exclusion criteria were incomplete 30-day follow-up, non-index procedures, or ongoing antibiotics. The main outcomes were postprocedural infectious adverse events and overall adverse events at the 30-day follow-up. Results: A total of 2144 procedures with indication of PSC were eligible for inclusion. AP was administered in 1407 (66%) of these procedures. Patients receiving AP were slightly younger (44 vs 46 years, P = 0.005) and had more comorbidities (ASA ≥3, 19.8% vs 13.6%; P < 0.001). Procedures with AP demonstrated an infectious adverse event rate of 3.3% compared to 4.5% for non-AP procedures (P = 0.19). Postprocedural infectious adverse events (odds ratio [OR] 0.76, 95% confidence interval [CI] 0.48-1.21) and overall adverse events (OR 0.79, 95% CI 0.60-1.04) did not differ between AP and non-AP. Conclusion: Patients with PSC who undergo ERCP have the same frequency of adverse events regardless of whether AP was used.
RESUMO
BACKGROUND AND OBJECTIVE: The most common way of closing the cystic duct in laparoscopic cholecystectomy is by using metal clips (>80%). Nevertheless, bile leakage occurs in 0.4%-2.0% of cases, and thus causes significant morbidity. However, the optimal number of clips needed to avoid bile leakage has not been determined. The primary aim of this study was to evaluate bile leakage and post-procedural adverse events after laparoscopic cholecystectomy concerning whether two or three clips were used to seal the cystic duct. METHODS: Using a retrospective observational design, we gathered data from the Swedish Registry for Gallstone Surgery and Endoscopic Retrograde Cholangiopancreatography (ERCP) (GallRiks). From 2006 until 2019, 124,818 patients were eligible for inclusion. These were nested to cohorts of 75,322 (60.3%) for uncomplicated gallstone disease and 49,496 (39.7%) with complicated gallstone disease. The cohorts were grouped by the number (i.e. two or three) of metal clips applied to the proximal cystic duct. The main outcome was 30-day bile leakage and post-procedural adverse events. RESULTS: No significant differences surfaced in the rate of bile leakage (0.8% vs 0.8%; P = .87) or post-procedural adverse events (three clips, 5.7% vs two clips, 5.4%; P = .16) for uncomplicated gallstone disease. However, for complicated disease, bile leakage (1.4% vs 1.0%; P < .001) and post-procedural adverse events (10.2% vs 8.6%; P < .001) significantly increased when the cystic duct was sealed with three clips compared with two. CONCLUSIONS: Because no differences in the rates of bile leakage or adverse events emerged in uncomplicated gallstone disease when a third clip was applied, a third clip for additional safety is not recommended in such cases. On the contrary, bile leakage and adverse events increased when a third clip was used in patients with complicated gallstone disease. This finding probably indicates a more difficult cholecystectomy rather than being caused by the third clip itself.
