Postoperative complications and hospital costs following open radical cystectomy: A retrospective study.

OBJECTIVES: To evaluate primarily the relationship between postoperative complications and hospital costs, and secondarily the relationship between postoperative complications and mortality, following radical cystectomy. METHODS: Postoperative complications were retrospectively examined for 147 patients undergoing radical cystectomy at a university hospital between January 2012 and July 2021. Complications were defined and graded using the Clavien-Dindo classification system. In-hospital cost was calculated using an activity-based costing methodology. Regression modelling was used to investigate the relationships among a priori selected perioperative variables, complications, and costs. The effect of complications on postoperative mortality was ascertained using time-dependent coefficients in a Cox proportional hazards regression model. RESULTS: 135 (92%) patients experienced one or more postoperative complications. The medians of hospital cost for patients who experienced no complications and those who experienced complications were $42,796.3 (29,222.9-53,532.5) and $81,050.1 (49,614.8-122,533.6) respectively, p < 0.001. Hospital costs were strongly associated with complication severity: Clavien-Dindo grade II complications increased costs by 45.2% (p < 0.001, 95% CI 19.1%-76.6%), and Clavien-Dindo grade III to V complications increased costs by 107.5% (p < 0.001, 95% CI 52.4%-181.8%). Each additional count of complication and increase in Clavien-Dindo complication grade increased the risk of mortality 1.28-fold (RR = 1.28, p = 0.006, 95% CI 1.08-1.53) and 2.50-fold (RR = 2.50, p = 0.012 95% CI 1.23-5.07) respectively. CONCLUSIONS: These findings demonstrate a high prevalence of complications following cystectomy and significant associated increases in hospital costs and mortality. Postoperative complications are a key target for cost-containment strategies. TRIAL REGISTRATION: Trial Registration: Australian New Zealand Clinical Trials Registry (ACTRN:12622000057785.

Laparoscopic choledochoscopy for choledocholithiasis is possible in the anatomical anomaly of left gallbladder.

Laparoscopic cholecystectomy (LC) is more challenging in the anatomical variation of left-sided gallbladder with the anomaly also highly related to biliary anomalies. Therefore, there has been a reluctance to operate close to the common bile duct (CBD) in left gallbladder patients, and thus choledocholithiasis is usually treated with endoscopic retrograde cholangiopancreatography (ERCP). There is emerging evidence that single stage LC and CBD exploration for choledocholithiasis may be superior to two stage LC and ERCP in terms of short-term and long-term morbidity, cost and length of stay. With the re-emergence of laparoscopic choledochoscopy, the purpose of this case report is to demonstrate the feasibility of this approach for choledocholithiasis.

Evaluating the effect of online surgical education on intraoperative cholangiogram interpretation: a pilot study.

BACKGROUND: Web-based educational tools can support practitioners in their early years of surgical training. Such tools may be an alternative platform to meet the changing needs in surgical training and professional development and may help explain complex surgical principles providing a structured learning platform that is relevant in the day-to-day surgical operating room setting. We investigated the impact of an online surgical education initiative on inter-observer variability and accuracy of IOC interpretation. METHODS: A convenience sample of seven surgical observers evaluated 100 IOCs before and after an online surgical series to evaluate their interpretation. The online video series characterized IOCs using nine key elements. The seven observers were surgical trainees of varying experience, from first-year surgical trainees to surgical fellows, within a metropolitan hospital in Melbourne, Australia. RESULTS: Inter-observer variability improved within six of nine key elements following the online tutorial. The accuracy of three out of these interpretations also significantly improved following the tutorial. Inter-observer agreement of proximal biliary opacification improved from moderate (kappa (κ) = 0.491) to good (κ = 0.725), with an improvement in accuracy from 95% to 99% (P = 0.009). Similarly, inter-observer agreements of cystic duct leaks dramatically improved from no agreement (κ = -0.089) to moderate agreement (κ = 0.548), with detection rates improving from 67% to 82% (P < 0.05). CONCLUSION: Through an innovative pilot online surgical education, inter-observer agreement and overall accuracy in the key elements of IOC interpretation improved. A larger multicenter study evaluating the effect of online surgical education on intraoperative cholangiogram interpretation is justified.

The Association of Postoperative Complications and Hospital Costs Following Distal Pancreatectomy.

Background: Understanding the financial implications associated with the complications post-distal pancreatectomy (DP) may be beneficial for the future optimisation of postoperative care pathways and improved cost-efficiency. The primary outcome of this retrospective study was the characterisation of the additional cost associated with postoperative complications following DP. The secondary outcome was the estimation of the prevalence, type and severity of complications post-DP and the determination of which complications were associated with higher costs. Methods: Postoperative complications were retrospectively examined for 62 adult patients undergoing distal pancreatectomy at an Australian university hospital between January 2012 and July 2021. Complications were defined and graded using the Clavien-Dindo (CVD) classification system. In-hospital cost of index admission was calculated using an activity-based costing methodology and was reported in US dollars at 2021 rates. Regression modelling was used to investigate the relationships among selected perioperative variables, complications and costs. Results: 45 patients (72.6%) experienced one or more postoperative complications. The median (IQR) hospital cost in US dollars was 31.6% greater in patients who experienced complications compared to those who experienced no complications ($40,717.8 [27,358.0-59,834.3] vs. $30,946.9 [23,910.8-46,828.1]). Costs for patients with four or more complications were 43.5% higher than for those with three or fewer complications (p = 0.015). Compared to patients with no complications, the median hospital costs increased by 17.1% in patients with minor complications (CVD grade I/II) and by 252% in patients who developed major complication (i.e., CVD grade III/IV) complications. Conclusion: Postoperative complications are a key target for cost-containment strategies. Our findings demonstrate a high prevalence of postoperative complications following distal pancreatectomy with number and severity of postoperative complications being associated with increased hospital costs.
