Background and objective Colorectal cancer (CRC) is the third most common malignancy and the second most deadly cancer worldwide. Powered equipment has transformed modern surgery, revolutionizing the delicacy, precision, and accuracy of many surgeries. The safety and efficacy of tissue dissection and artery sealing in colorectal surgery remain highly debatable. With the increased use of minimally invasive procedures in colon and rectal surgery, energy devices for tissue dissection and vascular sealing have become widely used. In light of this, we aimed at comparing the use of bipolar electrocautery and harmonic scalpel in CRC surgeries. Methods Our study was a hospital-based comparative study conducted at our tertiary care hospital. Fifty patients were divided equally into two groups by block randomization, and bipolar electrocautery was used in one group, and harmonic scalpel was used in the second group during surgery. The mean operative time, blood loss, and hospital stay were calculated in both groups. The comparison between bipolar electrocautery and harmonic scalpel was evaluated using independent t-tests. Results The mean operative time, blood loss, and hospital stay were significantly lower in the harmonic scalpel group than in the electrocautery group. The results were statistically significant (p < 0.001). Conclusion Based on our findings, the harmonic scalpel is a better energy source when compared to bipolar electrocautery in CRC surgeries.
Background and objectives Prostate diseases with an overall incidence of 9% are the leading cause affecting millions of males worldwide, with prostate cancer being the primary cause of death in males owing to benign prostatic hypertrophy being the primary cause of morbidity in the older age group. In light of this, we aimed to evaluate the utility of Magnetic Resonance Imaging in evaluating and characterization prostatic pathologies and grading prostatic cancer using PIRADS v2. Methods This was a study carried out on 50 patients with the age group ranging from 50 to 90 years with clinical suspicion or ultrasonographically demonstrable prostatic pathology and correlation of multiparametric MRI findings on various sequences with clinical features and histopathological findings and classification into groups of benign and malignant prostatic lesions and according to the PIRADS v2 scoring. Results Out of our study group, 4 cases were diagnosed with prostatitis and prostatic abscess, and 46 cases were categorized into PI-RADS, out of which most cases were classified into PI-RADS category V, followed by PI-RADS II and III. These were then evaluated with MR spectroscopy, of which 30 cases showed choline peak, and 16 cases showed citrate peak. The sensitivity and specificity for multiparametric MRI sequences combination detect the carcinoma of the prostate was calculated, and the Positive Predictive Value (PPV) & Negative Predictive Value (NPV) was found as 76% and 92%, respectively. Conclusion Based on our findings, we found out that the multiparametric MRI approach gives a wealth of practical information that has dramatically enhanced the detection and characterization of prostatic lesions. We also found out that morphological and functional sequencing improves the sensitivity and specificity of the lesions' identification and characterization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
