RESUMO
BACKGROUND: Laparoscopic cholecystectomy (LC) is the preferred treatment option in non-complicated symptomatic cholelithiasis. In some cases, the surgery might be complicated by different factors resulting in difficult LC. Ultrasound remains the first-line modality for diagnosing symptomatic cholelithiasis; however, its role in predicting difficult LC remains unclear. The aim of this study was to validate an ultrasonographic scoring system in predicting difficult LC. METHODS: We prospectively enrolled patients undergoing LC in a tertiary care unit over six months. All adult (≥18 years) patients undergoing LC for symptomatic cholelithiasis were included. Patients were excluded if they refused to consent, and those who underwent cholecystectomy for indications other than cholelithiasis. Patients were stratified into two groups based on intra-operative difficulty (easy LC and difficult LC) and were compared. Our primary outcome was radiologic difficulty among these groups. Univariate analysis and kappa statistics were performed. RESULTS: We identified 68 patients with an overall mean (SD) age of 42.2 (12.3) years, a mean (SD) weight of 74.1 (10.9) kg, and 73.5% were female. Of the study cohort, 52 patients had easy LC and 16 patients experienced difficult LC. Amongst the total, 14.7% suffered from diabetes mellitus, 29.4% had hypertension, 7.4% had a known ischemic heart disease, and 63% had a body mass index (BMI) ≥30 kg/m2 with no statistically significant difference between the two groups. On the Chi-square test, there was no statistical difference between the two groups in terms of ultrasonographic difficulty (p>0.05). However, we found a Kappa value of -0.127 (p=0.275) corresponding to a strong disagreement between the intraoperative and ultrasonographic difficulty. CONCLUSION: Despite its role in diagnosing cholelithiasis, an ultrasonographic assessment did not have a role in predicting difficult LC according to the present study. Further studies are required to develop a scoring system for predicting difficult LC based on clinical, laboratory, and ultrasonographic assessment.
RESUMO
BACKGROUND: Laparoscopic cholecystectomy (LC) is the preferred method for gallstone removal, but bile duct injuries remain a concern. Achieving the critical view of safety (CVS) is pivotal in preventing such injuries. The aim of this study was to compare the rates of difficult LC in those with CVS achieved compared to those with CVS not achieved. METHODS: We performed a single-center prospective study on all patients with ultrasound-confirmed symptomatic gallstones. Patients were excluded if they refused to consent or if they underwent LC for indications other than gallstone disease. Patients were stratified into two groups as CVS not achieved and CVS achieved groups and compared for outcomes. Our primary outcome was the rate of intraoperative difficulty on the modified Nassar scale (MNS). Statistical analysis was performed using SPSS version 25.0 (IBM Corp., Armonk, NY). RESULTS: We included 70 patients who underwent LC for gallstones (CVS not achieved = 24 and CVS achieved = 46). The mean (SD) age was 42.2 (12.3) years, and 73.5% were females. The mean (SD) weight in our study cohort was 74.1 (10.9) kg, and there was no difference between the two groups in terms of the baseline demographic characteristics, disease characteristics, and comorbid conditions (p > 0.05). On univariate analyses, achieving CVS was associated with lower rates of higher-grade operative difficulty on the MNS and lower rates of length of stay of more than one day. CONCLUSION: Achieving CVS is associated with easy LC based on significantly lower Nassar scores. These findings highlight the role of the MNS in the successful identification of the operative difficulty of LC and its correlation with achieving CVS.
RESUMO
BACKGROUND: Skin and soft tissue infections are one of the most common diseases presenting to the emergency department (ED). There is no study available on the management of Community-Acquired Skin and Soft Tissue Infections (CA-SSTIs) in our population recently. This study aims to describe the frequency and distribution of CA-SSTIs as well as their medical and surgical management among patients presenting to our ED. METHODS: We conducted a descriptive cross-sectional study on patients presenting with CA-SSTIs to the ED of a tertiary care hospital in Peshawar, Pakistan. The primary objective was to estimate the frequency of common CA-SSTIs presenting to the ED and to assess the management of these infections in terms of diagnostic workup and treatment modalities used. The secondary objectives were to study the association of different baseline variables, diagnostic modalities, treatment modalities, and improvement with the surgical procedure performance for these infections. Descriptive statistics were obtained for quantitative variables like age. Frequencies and percentages were derived for categorical variables. The chi-square test was used to compare different CA-SSTIs in terms of categorical variables like diagnostic and treatment modalities. We divided the data into two groups based on the surgical procedure. A chi-square analysis was conducted to compare these two groups in terms of categorical variables. RESULTS: Out of the 241 patients, 51.9% were males and the mean age was 34.2 years. The most common CA-SSTIs were abscesses, infected ulcers, and cellulitis. Antibiotics were prescribed to 84.2% of patients. Amoxicillin + Clavulanate was the most frequently prescribed antibiotic. Out of the total, 128 (53.11%) patients received some type of surgical intervention. Surgical procedures were significantly associated with diabetes mellitus, heart disease, limitation of mobility, or recent antibiotic use. There was a significantly higher rate of prescription of any antibiotic and anti-methicillin-resistant Staphylococcus aureus (anti-MRSA) agents in the surgical procedure group. This group also saw a higher rate of oral antibiotics prescription, hospitalization, wound culture, and complete blood count. CONCLUSION: This study shows a higher frequency of purulent infections in our ED. Antibiotics were prescribed more frequently for all infections. Surgical procedures like incision and drainage were much lower even in purulent infections. Furthermore, beta-lactam antibiotics like Amoxicillin-Clavulanate were commonly prescribed. Linezolid was the only systemic anti-MRSA agent prescribed. We suggest physicians should prescribe antibiotics appropriate to the local antibiograms and the latest guidelines.
