In this study, we aimed to compare the outcomes of surgical wound closure using staples versus sutures in clean elective abdominal surgeries. Objective: This prospective study aimed to assess the surgical site infection rate, closure time, and other postoperative outcomes associated with staple versus suture closure methods in clean elective abdominal surgeries. Methods: This prospective cohort study was conducted at the Pakistan Institute of Medical Sciences Hospital involving 236 patients undergoing clean elective abdominal surgeries from January 2024 to April 30, 2024. The patients were divided into two groups: the staple group (n=110) and the suture group (n=126). Baseline characteristics, including age, gender, BMI, smoking status, and comorbidities, were recorded for both groups. Surgical parameters such as mean operating time and closure time were measured. Postoperative outcomes, including surgical site infection, prolonged wound discharge (> four days), abscess formation, wound dehiscence, pain (assessed using Visual Analogue Score), and cosmetic appearance, were compared between the two groups using appropriate statistical methods. Results: The mean age of patients in the staple group was 52.45 ± 15.41 years, while in the suture group, it was 56.34 ± 14.69 years (p = 0.99). There were no significant differences in baseline characteristics between the two groups. The mean operating time was 91.13 ± 12.8 minutes in the staple group and 88.48 ± 25.55 minutes in the suture group (p = 0.17). However, the closure time was significantly shorter in the staple group (6.6 ± 1.4 minutes) compared to the suture group (15.1 ± 3.2 minutes) (p = 0.004). There were no significant differences in the rates of surgical site infection, abscess formation, or wound dehiscence between the two groups. However, the incidence of prolonged wound discharge (>4 days) was significantly higher in the staple group (11 cases) compared to the suture group (4 cases) (p = 0.001). Patients in the staple group also reported higher pain scores (Visual Analogue Score ≥ 3) compared to the suture group (p = 0.021). Additionally, the two groups had no significant difference in cosmetic appearance (p = 0.12). Conclusion: In clean elective abdominal surgeries, staple closure resulted in shorter closure times but was associated with a higher incidence of prolonged wound discharge and higher pain scores compared to suture closure.

Although considered minimally invasive, port site infections (PSI) remain a concern, potentially impacting patient outcomes and recovery times. Understanding the frequency and risk factors associated with PSI is essential for improving surgical practices and patient safety. Objective: To assess the frequency of port site infection in patients undergoing laparoscopic cholecystectomy. Methods: A cross-sectional study was conducted in the surgery department from January 2, 2024, to April 2, 2024. The study enrolled 120 patients presenting for laparoscopic cholecystectomy. The mean age of the patients was 34.30 ± 9.57 years, and the mean BMI was 25.32 ± 2.21 kg/m². The frequency of PSI was determined, and its association with BMI was analysed using statistical methods, with a significance level set at P < 0.05. Results: The PSI frequency was 6.7% (8 out of 120 patients). There was a notable association between increasing BMI and the occurrence of PSI (P = 0.005). Conclusion: The frequency of PSI in patients undergoing laparoscopic cholecystectomy in this study was 6.7%, suggesting that the procedure is relatively safe for gallbladder removal. Higher BMI was significantly associated with an increased risk of PSI, indicating the need for targeted strategies to mitigate this risk in patients with elevated BMI.","PeriodicalId":504575,"journal":{"name":"Biological and Clinical Sciences Research Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141386922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the various coronary arteries, the Left Anterior Descending (LAD) artery is particularly interesting due to its significant role in supplying blood to a large portion of the heart muscle. Objectives: To assess the efficacy of the ‘four-variable formula’ in identifying left anterior descending (LAD) coronary artery occlusion, ‘serial electrocardiogram (ECG) analyses’ should be performed on individuals exhibiting minor alterations in the ‘anterior leads.’ Methodology: ‘This study was a cross-sectional study conducted at the Armed Forces Institute of Cardiology’ (AFIC) from Jan 2023 to June 2023. The primary aim was to ‘evaluate the predictive performance of the Four-Variable Formula in detecting Left Anterior Descending (LAD) coronary artery occlusion’ using serial electrocardiogram (ECG) analyses. Upon presentation, a standard 12-lead ECG was performed on each patient. Serial ECGs were conducted at 30-minute intervals for the first two hours or until a definitive diagnosis was made. Following the ECG analyses, ‘all patients were taken to the catheterization lab for coronary angiography within 24 hours of presentation’. The angiographic results served as the gold standard for diagnosing LAD occlusion. An experienced interventional cardiologist, blinded to the ECG findings, performed and interpreted the angiograms. Results: The study included 360 patients, with a mean age of 62 ±11 years (range 32-80 years). The cohort comprised 219 males (62%) and 141 females (38%). Common risk factors included hypertension (69%), diabetes mellitus (46%), smoking (51%), and a family history of coronary artery disease (29%). Coronary angiography identified LAD occlusion in 139 patients (38%) and no significant LAD occlusion in 221 patients (62%). The results suggested that the Four-Variable Formula could be integrated into routine clinical practice to enhance early detection of significant coronary artery disease, particularly in settings where immediate access to coronary angiography is limited. Future studies with more extensive, multicenter cohorts could further validate these findings and potentially lead to widespread adoption of this predictive tool. Conclusion: Our findings suggest that the Four-Variable Formula holds promise as a non-invasive diagnostic tool in emergency settings, aiding ‘in the early identification of patients at risk’ of significant coronary artery disease. By incorporating the formula into clinical practice algorithms, healthcare providers may expedite triage decisions and facilitate timely interventions, ultimately improving patient outcomes.","PeriodicalId":504575,"journal":{"name":"Biological and Clinical Sciences Research Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141384489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objectives: The study aims to find the ESWL efficacy for various density stones (HU) on plain CT scans. Methods: This observational study was conducted at CMH Lahore from February 17, 2024, to May 16, 2024. Data were collected from 180 patients suffering from renal stones. Males represented 60% (108 patients), while females 40% (72 patients). Predominantly, stones were located in the renal pelvis (45%), followed by the upper ureter (30%) and lower ureter (25%). The mean stone size was 10 mm, ranging from 5 to 20 mm, with a corresponding mean stone density of 900 Hounsfield Units (HU) as measured on Plain CT Scan. Results: Data were collected from 180 patients. The mean age of the patients was 50.98±2.34 years. There were 60% male and 40% female patients. According to stone location, 45% are located at the renal pelvis, 30 at the upper ureter and 25% at the lower ureter. A mean reduction in the stone size of 65% post-treatment underscores the procedure's ability to facilitate stone disintegration. Stone-free rates varied based on stone density, with higher rates observed for stones with lower densities: 85% for stones ≤ 700 HU, 75% for stones > 700 HU and ≤ 1000 HU, and 65% for stones > 1000 HU. Conclusion: It is concluded that an accurate assessment of stone density and ESWL score is vital in directing treatment decisions and upgrading outcomes for patients going through ESWL for urinary stones.
