RESUMO

Chilaiditi's sign is the presence of pseudopneumoperitoneum caused by colonic distension and interposition with the liver on radiographic films. Most patients with Chilaiditi's sign are asymptomatic. Chilaiditi's syndrome is defined as the development of abdominal pain or symptoms of bowel obstruction along with the presence of Chilaiditi's sign. It is a rare entity and it poses significant diagnostic challenges due to its similar radiographic appearance to pneumoperitoneum. Most patients with Chilaiditi syndrome can be managed conservatively. However, surgery is indicated for those who do not respond to conservative management or for suspicion of severe complications such as bowel ischaemia or perforation. In this case report, we described the surgical management of a patient who presented with bowel obstruction and significant hepatic displacement from Chilaiditi syndrome.

RESUMO

Hepatic artery aneurysms are a rare phenomenon but their diagnosis and prompt treatment are imperative due to a high risk of mortality and complications. Appropriate management depends on patient characteristics, anatomical location of the aneurysm, operative risk and collateral arterial supply. Management options include surgical and endovascular approaches. The endovascular approach has gained popularity over recent years as it is an effective and less invasive alternative to surgical management. In this case report, we present a giant common hepatic artery aneurysm and its successful endovascular management. The patient had a complete resolution of symptoms after the procedure and remained well 8 months postprocedure.

RESUMO

BACKGROUND: Evidence has revealed that nonpharmaceutical interventions (NPIs) were effective in attenuating the spread of COVID-19. However, policymakers have encountered difficulty in identifying the most effective policies under different circumstances. This study investigated the relative effectiveness of different NPIs and vaccination in prolonging COVID-19 case doubling time (DT). METHODS: The study sample consisted of observations from 137 countries during 1 January 2020 to 13 June 2021. DT was calculated on a daily basis per country. Data were retrieved from the Oxford COVID-19 Government Response Tracker, World Development Indicators, and Worldwide Governance Indicators. To capture policy intervention dynamics, we combined a random-effect growth-curve model with nonstandard interrupted time series analysis. We also evaluated the association of policy measures with DT for different outbreak stages and levels of government effectiveness. RESULTS: Vaccine rollouts, workplace closures, and school closures were relatively effective. For each day that these measures were implemented, the DT increased by 1.96% (95% confidence interval (CI) = 0.63 to 3.29; P = 0.004), 1.41% (95% CI = 0.88 to 1.95%; P < 0.001) and 1.38% (95% CI = 0.95 to 1.81%; P < 0.001), respectively. Workplace and school closures were positively associated with DT at all stages; however, the associations weakened in later stages, where vaccine rollouts appeared to be most effective in prolonging DT (95% CI = 1.51% to 3.04%; P < 0.05). For countries with a high level of government effectiveness, most of the containment measures evaluated were effective; vaccine rollouts had the greatest effect size. For countries with medium or low levels of government effectiveness, only the closure of workplaces was consistently associated with prolonged DT. CONCLUSIONS: The effectiveness of vaccine rollouts outweighed that of NPIs, especially in the later outbreak stages. However, vaccination was not associated with prolonged case DT in countries with lower levels of government effectiveness, probably due to low vaccine coverage. Among the NPIs examined, workplace closures were highly effective across all outbreak stages and levels of government effectiveness. Our findings suggest that mass vaccination is critical to reducing SARS-CoV-2 transmission, especially in countries where NPIs are less effective.

RESUMO

Background: Common bile duct exploration (CBDE) is performed uncommonly. Issues surrounding its uptake in the laparoscopic era include perceived difficulty and lack of training. We aim to determine the success of CBDE performed by "specialist" and "nonspecialist" common bile duct (CBD) surgeons to determine whether there is a substantial difference in success and safety. Methods: A 10-year retrospective audit was performed of patients undergoing CBD exploration for choledocholithiasis. Northern Health maintains an on-call available "specialist" CBD surgeon roster to aid with CBDE. Results: Five hundred fifty-one patients were identified, of which 489/551 (88.7%) patients had stones successfully cleared. Specialists had a higher success rate (90.8% versus 82.6%, P = .008), associated with a longer surgical time. Method (transcystic or transductal), approach (laparoscopic or open), and indication for operation were similar between groups. There was no significant difference in complications. To be confident of a surgeon having an 80% success rate, 70 procedures over 10 years were required, however, an "in-control" 50% success rate may only require 1 procedure per year. Conclusion: While specialist CBDE surgeons have improved success rates, nonspecialist general surgeons also have a good and comparable success rate with an equivalent complication rate. With realistic annual targets, nonspecialist CBD surgeons should be encouraged to perform CBDE in centers without specialist support.

RESUMO

BACKGROUND: Laparoscopic common bile duct exploration (LCBDE) can be performed to treat choledocholithiasis at the time of laparoscopic cholecystectomy. The aim of this study was to identify factors that predict the success of LCBDE. MATERIALS AND METHODS: A retrospective audit was performed on patients who underwent LCBDE for the management of choledocholithiasis at Northern Health between 2008 and 2018. RESULTS: A total of 513 patients were identified with an overall success rate of 90.8%. Most LCBDE were done through a transcystic approach with the remainder through a choledochotomy. When comparing patients with a successful operation to those that were unsuccessful, univariate analysis demonstrated significant differences in preoperative white cell count and number of duct stones found. Age and elevated nonbilirubin liver function tests were found to be significant factors associated with the failure of LCBDE on multivariate analysis. The likelihood of a failed operation in those with multiple stones was observed to be almost halved compared with patients with single stone although this did not reach significance [odds ratio (OR): 0.53, 95% confidence interval (CI): 0.28-1.01, P=0.055]. Multivariate analysis indicated that unsuccessful procedures (OR: 10.13, 95% CI: 4.34-23.65, P<0.001) and multiple duct stones (OR: 3.79, 95% CI: 1.66-8.67, P=0.002) were associated with an increased risk of severe complications. CONCLUSIONS: A single impacted stone may be more difficult to remove, however complications were more likely to be associated with multiple duct stones. With no other clinically relevant predictive factors, and because of the high success of the procedure and the low morbidity, LCBDE remains an option for all patients with choledocholithiasis.

RESUMO

BACKGROUND AND OBJECTIVES: Event-based surveillance and rapid risk assessment for acute public health events are essential in emerging infectious disease control. Since detecting the unusual signal in Wuhan in December 2019, Taiwan has been aligning risk management to policy planning via conducting regular risk assessments to combat the coronavirus disease 2019 (COVID-19). This article aims to provide some insights into Taiwan's experiences and corresponding actions for the outbreak. RESULTS: The COVID-19 risk level in Taiwan was raised to "moderate-to-high" in mid-January 2020 when neighboring countries had reported cases and the human-to-human transmission became obvious. The risk level became "high" on 24 January due to China's escalating epidemic situation and imposed a lockdown in Wuhan. We learned that the commander recognized the importance of risk assessments and considered advice from the experts was crucial in making the correct decision at the early stage of the crisis. CONCLUSIONS: Given the surge of COVID-19 cases globally, understanding the evidence-driven mobilizations via detailed risk assessments in Taiwan may be an example worth considering for other countries. We believe that strengthening a global epidemic intelligence network and sharing information in a timely and transparent manner are essential for confronting new challenges of COVID-19 and other emerging infectious diseases.
