Cross-Sectional Assessment of Surgical Consult Volume to Determine Optimal Residency Staffing During COVID-19 Lockdown.

INTRODUCTION: Since the start of the COVID-19 pandemic, there have been protocols initiated to reduce its transmission. Despite these measures, critical hospital staff are still at risk of infection with subsequent loss of the workforce. The purpose of this study was to determine the difference in surgical consult volume during a COVID-19 pandemic to extrapolate staffing requirements. MATERIALS AND METHODS: We conducted a single-center cross-sectional study of surgical consult volume during the COVID-19 pandemic. Data were obtained from routine administrative records which track daily volume of all surgical consults, including trauma center activations, performed by the general surgery residency. We compared the mean number of consults across periods defined by salient lockdown and reopening events in the community using one-way analysis of variance. RESULTS: We found a statistically significant decrease in the mean number of surgical consults during the state-mandated lockdown/stay-at-home orders (P < 0.001). However, there was no significant difference in the mean number of surgical consults when only comparing prelockdown and postlockdown (lockdown period excluded). CONCLUSIONS: No change in expected consult volume should be assumed unless there is a complete lockdown. During a complete population lockdown/stay-at-home orders, decreased staffing can be scheduled to allow considerations of decreasing community or in-hospital spread of communicable disease. Once reopening happens, even if only partly, full staffing may be needed to accommodate a return to normal consult volume.

Liver resection for metastatic GIST tumor improves survival in the era of tyrosine kinase inhibitors: a systematic review and meta-analysis.

INTRODUCTION: Survival for gastrointestinal stromal tumor (GIST) has been increasing over the years after the introduction of tyrosine kinase inhibitors. However, the role of metastasectomy for GIST is still controversial. Patients are currently treated with imatinib or sunitinib in case of imatinib failures as optimal medical therapy for metastatic GIST. METHODS: The Pubmed, EMBASE, and Cochrane Library were systematically searched. Overall survival following liver resection ± tyrosine kinase inhibitor treatment for metastatic GIST was compared to treatment with tyrosine kinase inhibitors alone. RESULTS: Eleven studies including both randomized control trials and retrospective cohort studies were included in the final analysis with a total of 988 patients. Seven studies encompassed data on 556 patients with isolated liver metastases (219 surgery ± drug groups and 337 drug-only groups) were included. Overall survival was significantly improved in patients undergoing liver resection ± drug therapy in comparison to drug therapy alone. [HR (95%CI) = 2.10 (1.58, 2.79); p<0.00001]. Subgroup analysis showed that patients also had improved progression free survival based on 4 studies. [HR (95%CI) = 1.92 (1.43, 2.56); p<0.00001]. In case of concurrent liver and peritoneal metastases, patients showed improved overall survival with aggressive surgical approaches based on 10 studies. [HR (95%CI) = 1.90 (1.56, 2.31); p<0.00001]. CONCLUSION: This meta-analysis found that liver resection for patients with metastatic GIST regardless of peritoneal metastases improved progression free and overall survival in conjunction with tyrosine kinase inhibitors as compared with medical therapy alone. Furthermore, liver resections did not have any immediate detrimental impact on survival in the group of patients selected.

Radiation therapy prior to a pancreaticoduodenectomy for adenocarcinoma is associated with longer operative times and higher blood loss.

BACKGROUND: Pancreatic adenocarcinoma is currently the fourth leading cause of cancer-related deaths in the United States. In patients with "borderline resectable" disease, current National Comprehensive Cancer Center guidelines recommend the use of neoadjuvant chemoradiation prior to a pancreaticoduodenectomy. Although neoadjuvant radiotherapy may improve negative margin resection rate, it is theorized that its administration increases operative times and complexity. AIM: To investigate the association between neoadjuvant radiotherapy and 30-d morbidity and mortality outcomes among patients receiving a pancreaticoduodenectomy for pancreatic adenocarcinoma. METHODS: Patients listed in the 2015-2019 National Surgery Quality Improvement Program data set, who received a pancreaticoduodenectomy for pancreatic adenocarcinoma, were divided into two groups based off neoadjuvant radiotherapy status. Multivariable regression was used to determine if there is a significant correlation between neoadjuvant radiotherapy, perioperative blood transfusion status, total operative time, and other perioperative outcomes. RESULTS: Of the 11458 patients included in the study, 1470 (12.8%) underwent neoadjuvant radiotherapy. Patients who received neoadjuvant radiotherapy were significantly more likely to require a perioperative blood transfusion [adjusted odds ratio (aOR) = 1.58, 95% confidence interval (CI): 1.37-1.82; P < 0.001] and have longer surgeries (insulin receptor-related receptor = 1.14, 95%CI: 1.11-1.16; P < 0.001), while simultaneously having lower rates of organ space infections (aOR = 0.80, 95%CI: 0.66-0.97; P = 0.02) and pancreatic fistula formation (aOR = 0.50, 95%CI: 0.40-0.63; P < 0.001) compared to those who underwent surgery alone. CONCLUSION: Neoadjuvant radiotherapy, while not associated with increased mortality, will impact the complexity of surgical resection in patients with pancreatic adenocarcinoma.
