ABSTRACT

Incidental gastrointestinal tract (GIT) [18F]-Fluorodeoxyglucose (FDG) uptake in positron emission technology/computed tomography (PET/CT) is an unexpected and often complicated finding for clinicians. This retrospective study reviewed 8991 charts of patients who underwent PET/CT: 440 patients had incidental GIT uptake, of which 80 underwent endoscopy. Patient characteristics, imaging parameters, and endoscopic findings were studied. Of the 80 patients, 31 had cancer/pre-cancer lesions (16 carcinomas; 15 pre-malignant polyps). Compared to patients with benign/absent lesions, patients with cancer/pre-cancer lesions were significantly older (p = 0.01), underwent PET/CT for primary evaluation/staging of cancer (p = 0.03), had focal GIT uptake (p = 0.04), and had lower GIT uptake (p = 0.004). Among patients with focal uptake, an SUVmax of 9.2 had the highest sensitivity (0.76) and specificity (0.885) in detecting cancer/pre-cancerous lesions. Lower GIT uptake was most common in the sigmoid colon, and upper GIT uptake was most frequent in the stomach. In a bivariate analysis, predictors of cancer/pre-cancer were older age, PET/CT indicated for primary evaluation, focal uptake, uptake in the lower GIT, and higher SUVmax. Further endoscopic investigation is warranted for patients with incidental GIT uptake, especially in the elderly or those presenting for primary evaluation with PET/CT, with the following findings on imaging: lower GIT uptake, focal uptake, or high SUVmax.

ABSTRACT

GOALS AND BACKGROUND: We aimed to develop a novel 1-year mortality risk-scoring system that includes use of antithrombotic (AT) drugs and to validate it against other scoring systems in patients with acute gastrointestinal bleeding (GIB). STUDY: We developed a risk-scoring system from prospectively collected data on patients admitted with GIB between January 2013 and August 2020, who had at least 1- year of follow-up. Independent predictors of 1-year mortality were determined after adjusting for the following confounders: the age-adjusted Charlson Comorbidity Index (CCI) (divided into 4 groups: CCI-0=0, CCI-1=1 to 3, CCI-2=4 to 6, CCI-3 ≥7), need for blood transfusion, GIB severity, need for endoscopic therapy, and type of AT. The risk score was based on independent predictors. RESULTS: Five hundred seventy-six patients were included and 123 (21%) died at 1-year follow-up. Our risk -score was based on the following: CCI-2 (2 points), CCI-3 (4 points), need for blood transfusion (1 point), and no use of aspirin (1 point), as aspirin use was protective (maximum score=6). Patients with higher risk scores had higher mortality. The model had a better predictive accuracy [AUC=0.82, 95% confidence interval (0.78-0.86), P <0.0001] than the Rockall score for upper GIB (Area Under the Curve (AUC)=0.68, P <<0.0001), the Oakland score for lower GIB (AUC=0.69, p =0.004), or the Shock Index for all (AUC=0.54, P <0.0001). CONCLUSION: A simple and novel score that includes use of AT upon admission accurately predicts 1-year mortality in patients with GIB. This scoring system may help guide follow-up decisions and inform the prognosis of patients with GIB.

ABSTRACT

The aim of this study is to identify the optimal timing for cholecystectomy for acute cholecystitis. Patients undergoing cholecystectomy for acute cholecystitis from the National Surgery Quality Improvement Program database between 2014 and 2016 were included. The patients were divided into 4 groups, those who underwent surgery at days 0, 1, 2, or 3+ days. The primary outcome was short-term surgical morbidity and mortality. A total of 21,392 patients were included. After adjusting for confounders, compared to day 0 patients, those who underwent surgery at day 1 and day 2 had lower composite morbidity rate, while day 3+ patients had significantly higher bleeding and mortality rate. Subgroup analysis shows this trend to be more significant in the elderly and in diabetic patients who were delayed. Delay in cholecystectomy for over 72 h from admission is associated with statistically significant increase in bleeding and mortality.

ABSTRACT

BACKGROUND/AIM: Distal pancreatectomy (DP) accounts for 25% of all pancreatic resections. Complications following DP occur in around 40% of the cases. Our aim is to analyze short-term surgical outcomes of DP based on whether the indication for resection was benign or malignant pathology, as well as the effect of the surgical approach, open versus laparoscopic on morbidity and mortality. METHODS: We studied all patients undergoing DP from the National Surgery Quality Improvement Program (NSQIP) targeted pancreatectomy participant use file from 2014 to 2016. The patients were divided into 2 groups, those who underwent DP for benign diseases (DP-B) and those who underwent DP for malignant diseases (DP-M). We performed multivariate logistic regression to evaluate the association between benign or malignant distal pancreatectomies and 30-day outcomes. We included clinically and/or statistically significant confounders into the models. We also conducted the same analysis in the subgroups of open and laparoscopic DP. RESULTS: Three thousand five hundred and seventy-nine patients underwent distal pancreatectomy. The most common indication for surgery was malignant disease in 1894 (53%). Thirty-day mortality occurred in 0.4% of DP-B compared to 1.3% DP-M. On multivariate analysis, no significant difference was found in mortality or in the risk of pancreatic fistula between the 2 groups. Bleeding (p = 0.002) and composite morbidity (p = 0.01) were significantly higher in the DP-M group. Among composite morbidities, thromboembolism was significantly associated with DP-M (OR 2.1, p = 0.0004) only when performed with an open approach. CONCLUSION: DP-M is associated with a significantly higher risk of post-operative bleeding, thromboembolism, and sepsis compared to DP-B but no significant increase in mortality. When further analyzing the impact of the operative approach on morbidity, there was an increased rate of post-operative thromboembolic in the DP-M group when the surgery was performed in an open manner and this increased risk was no longer statistically significant if the DP-M was performed using a minimally invasive approach.
