Factors affecting the recurrence of acute cholecystitis after treatment with percutaneous cholecystostomy.

BACKGROUND: The aim of this study was to determine the recurrence rate of patients who did not have interval cholecystectomy after treatment with percutaneous cholecystostomy and to investigate the factors that may affect the recurrence. METHODS: Patients who did not undergo interval cholecystectomy after percutaneous cholecystostomy treatment between 2015 and 2021 were retrospectively screened for recurrence. RESULTS: 36.3% of the patients had recurrence. Recurrence was found more frequently in patients with fever symptoms at the time of admission to the emergency department (p = 0.003). Recurrence was found to be more frequent in those who had a previous cholecystitis attack (p = 0.016). It was determined that patients with high lipase and procalcitonin levels had statistically more frequent attacks (p = 0.043, p = 0.003). It was observed that the duration of catheter insertion was longer in patients who had relapses (p = 0.019). The cut-off value for lipase was calculated as 15.5, and the cut-off value for procalcitonin as 0.955, in order to identify patients at high risk for recurrence. In the multivariate analysis for the development of recurrence, presence of fever, a history of previous cholecystitis attack, lipase value higher than 15.5 and procalcitonin value higher than 0.955 were found to be risk factors. CONCLUSIONS: Percutaneous cholecystostomy is an effective treatment method in acute cholecystitis. Insertion of the catheter within the first 24 h may reduce the recurrence rate. Recurrence is more common in the first 3 months following removal of the cholecystostomy catheter. Having a previous history of cholecystitis attack, fever symptom at the time of admission, elevated lipase and procalcitonin are risk factors for recurrence.

Do Stoma Formation and Use of Vacuum Assisted Closure System Affect Mortality in Perineal Fournier's Gangrene?

OBJECTIVE: The aim of this study was to identify the effects of creation of stoma and the use of vacuum-assisted closure systems on postoperative mortality and hospital stay in patients with Fournier's gangrene involving anorectal region. STUDY DESIGN: A retrospective study. PLACE AND DURATION OF STUDY: Department of General Surgery, University of Health Sciences Tepecik Training and Research Hospital, Izmir, Turkey, from January 2010 to September 2021. METHODOLOGY: A total of 66 patients with Fournier's gangrene with anorectal involvement were selected from hospital records and divided into two groups as alive and exitus. Differences between these two groups and the factors affecting mortality were analysed with the SPSS statistics software, version 25.0. The value of p<0.05 was considered statistically significant. RESULTS: The mean age of the patients was 57.9±12.9 years, however, age was higher in exitus group (p=0.013). Debridement count was significantly raised in patients with vacuum assisted closure system (p<0.001). The use of vacuum-assisted closure system was associated with a longer hospital stay (p=0.042). Both stoma creation and the use of vacuum-assisted closure system were not found as risk factors for higher mortality. CONCLUSION: Stoma creation and the use of vacuum-assisted closure systems have no effect on mortality in patients of Fournier's gangrene with anorectal involvement. Urogenital involvement may be considered as a risk factors for mortality. KEY WORDS: Fournier's gangrene, Vacuum-assisted closure system, Stoma, Anorectal region, Perineum, Mortality.

Effect of Early Versus Delayed Laparoscopic Cholecystectomy on Postoperative Morbidity and Difficult Cholecystectomy in Patients With Grade II Cholecystitis According to Tokyo 2018 Guidelines: A Prospective Study.

BACKGROUND: The timing of the cholecystectomy in patients with acute cholecystitis is still controversial. In our study, we aimed to investigate the effect of early and delayed cholecystectomy on difficult cholecystectomy, morbidity and mortality in patients diagnosed with Grade II acute cholecystitis according to Tokyo 2018 guidelines. METHODS: Patients who presented to the emergency department and diagnosed with Grade II acute cholecystitis between December 2019 and June 2021 were included in this study. Cholecystectomy was performed within 7 days and 6 weeks after symptom onset. The effect of early and delayed cholecystectomy was observed. RESULTS: A total of 92 patients were included in the study. The timing of cholecystectomy was not a risk factor for mortality, morbidity and difficult cholecystectomy. The conversion rate was higher in delayed group (P = .007). The bleeding was significantly higher in early group (P = .033). Total hospital stay was higher in delayed group (P < .001). CRP was a predictive parameter for increased Parkland score in early group (P < .001). CONCLUSIONS: Delayed cholecystectomy does not facilitate cholecystectomy in patients with Grade II acute cholecystitis. Early cholecystectomy can be performed safely and high CRP levels can be used to determine difficult cholecystectomy in early period.

Effectiveness of laser hemorrhoidoplasty in the treatment of hemorrhoidal disease.

INTRODUCTION: Minimally invasive techniques still continue to maintain their popularity in hemorrhoidal disease. In this study, we aimed to present the symptomatic recovery and recurrence rates, post-operative pain levels, and complication rates of patients treated with the laser hemorrhoidoplasty (LHP) method in our clinic. METHODS: The data of patients who underwent LHP due to Grades 2, 3, and 4 internal hemorrhoidal disease in our clinic were reviewed retrospectively. The patients enrolled in the study were followed for at least 6 months (6 months, 1 year, and 2 years) and their results were analyzed. RESULTS: A total of 103 patients were included in the study. Seventy-five (72.8%) of them were male and the mean age was 41.6 ± 13.6 years. The mean operation time was 17.9 ± 5.2 min and minor complications developed in 3 (2.9%) patients postoperatively. Mean time to return to normal daily life was 2.17 (1-11) days. Recurrence developed in 16 (17.6%) patients with Grades 2 and 3 disease and in 6 (50%) of 12 patients with Grade 4 disease (p = 0.019). CONCLUSION: LHP is a popular procedure which is effective in selected patient groups with acceptable recurrence rates.

Effect of skeletal muscle area and prognostic nutritional index in periampullary tumors.

INTRODUCTION: The skeletal muscle area (SMA) and prognostic nutritional index (PNI) are both considered as predictive parameters for mortality and morbidity for various type of cancer. In this study, we aimed to identify the effects of pre-operative SMA and PNI values on post-operative mortality and morbidity in patients with periampullary region tumors (PRT). METHODS: Patients between 2010 and 2020 were retrospectively analyzed and divided into two groups according to SMA and PNI cutoff values. Univariate and multivariate analysis was performed to find potential risk factors. RESULTS: The mean age was 65.94 ± 11.242 and 54 (60.6%) of the patients were male. Hypertension was found a reducing factor for morbidity in both univariate and multivariate analysis (p = 0.039; p = 0.045). Chronic obstructive pulmonary disease and low PNI were found as factors affecting mortality in univariate analysis (p = 0.046; p = 0.014). However, only low PNI was found as an enhancing factor for mortality in multivariate analysis. CONCLUSION: Although SMA is not a risk factor for post-operative morbidity and mortality, PNI can be considered as a risk factor for mortality in patients with PRT.

INTRODUCCIÓN: El área del músculo esquelético (SMA) y el índice nutricional pronóstico (PNI) se consideran parámetros predictivos de mortalidad y morbilidad para varios tipos de cáncer. En este estudio, nuestro objetivo fue identificar los efectos de los valores preoperatorios de SMA y PNI sobre la mortalidad postoperatoria. y morbilidad en pacientes con tumores de la región periampular (PRT). MÉTODOS: Los pacientes entre 2010-2020 fueron analizados retrospectivamente y divididos en dos grupos según los valores de corte de SMA y PNI. Se realizaron análisis univariados y multivariados para encontrar posibles factores de riesgo. RESULTADOS: La edad media fue de 65.94 ± 11.242 y 54 (60.6%) de los pacientes eran varones. Se encontró que la hipertensión es un factor reductor de la morbilidad tanto en el análisis univariado como en el multivariado (p = 0.039; p = 0.045). La EPOC y el PNI bajo se encontraron como factores que influyen en la mortalidad en el análisis univariante (p = 0.046; p = 0.014). Sin embargo, solo el PNI bajo se encontró como un factor potenciador de la mortalidad en el análisis multivariado. CONCLUSIÓN: Aunque la SMA no se consideró un factor de riesgo de morbilidad y mortalidad posoperatorias; La PNI puede considerarse un factor de riesgo de mortalidad en pacientes con PRT.

Prognostic Nutritional Index in Short-term Postoperative Outcomes in Hepaticojejunostomy.

OBJECTIVE: To investigate the utility of prognostic nutritional index (PNI) on short-term complications, biliary fistula, mortality, and morbidity in patients undergoing hepaticojejunostomy (HJ) procedure. STUDY DESIGN: Observational study. PLACE AND DURATION OF STUDY: Tepecik Training and Research Hospital, Izmir, Turkey, between January 2018 and January 2020. METHODOLOGY: Patients who underwent elective HJ for benign and malignant reasons were scanned retrospectively using the hospital digital record system. Many data such as chronic diseases and PNI values of patients, postoperative 30-day mortality and morbidity, days of hospital stay (HS), postoperative complications, and data of surgery were analyzed. RESULTS: A total of 81 patients, of whom 42 (52%) were males and 39 (48%) were females, were included in the study. The mean age of the patients was 65.8 ±11.3. In 53 patients (65.4%), surgeries were performed due to malignancy. In 19 (23.4%) patients, grade 3 and 4 complications according to Clavien-Dindo Classification were observed in 12 patients (14.8%), and postoperative 30-day mortality was observed. The rate of grade 3 and 4 complications increased in patients with a PNI below 45, it was not statistically significant (p=0.165). The mortality rate was 4.5% in patients with PNI>45, and 18.6% in patients with PNI<45 but this difference was not significant (p=0.165). The mean HS was significantly shorter in patients with PNI>45 (p=0.02). CONCLUSION: At PNI>45, many complications and hospital stay become markedly shorter. Large multi-centre randomised future studies are required to confirm these findings. KEY WORDS: Prognostic nutritional index, Hepatic duct, Biliary tract, Biliary fistula.

SARS-CoV-2 Mutations and their Viral Variants.

Mutations in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) occur spontaneously during replication. Thousands of mutations have accumulated and continue to since the emergence of the virus. As novel mutations continue appearing at the scene, naturally, new variants are increasingly observed. Since the first occurrence of the SARS-CoV-2 infection, a wide variety of drug compounds affecting the binding sites of the virus have begun to be studied. As the drug and vaccine trials are continuing, it is of utmost importance to take into consideration the SARS-CoV-2 mutations and their respective frequencies since these data could lead the way to multi-drug combinations. The lack of effective therapeutic and preventive strategies against human coronaviruses (hCoVs) necessitates research that is of interest to the clinical applications. The reason why the mutations in glycoprotein S lead to vaccine escape is related to the location of the mutation and the affinity of the protein. At the same time, it can be said that variations should occur in areas such as the receptor-binding domain (RBD), and vaccines and antiviral drugs should be formulated by targeting more than one viral protein. In this review, a literature survey in the scope of the increasing SARS-CoV-2 mutations and the viral variations is conducted. In the light of current knowledge, the various disguises of the mutant SARS-CoV-2 forms and their apparent differences from the original strain are examined as they could possibly aid in finding the most appropriate therapeutic approaches.

Host variations in SARS-CoV-2 infection.

The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the zoonotic pathogen that causes the "Coronavirus Disease of 2019 (COVID-19)", and COVID-19 itself is yet to be thoroughly understood. Both the disease as well as the mechanisms by which the host interacts with the SARS-CoV-2 have not been fully enlightened. The epidemiological factors -e.g. age, sex, race-, the polymorphisms of the host proteins, the blood types and individual differences have all been in discussions about affecting the progression and the course of COVID-19 both individually and collectively, as their effects are mostly interwoven. We focused mainly on the effect of polymorphic variants of the host proteins that have been shown to take part in and/or affect the pathogenesis of COVID-19. Additionally, how the procedures of diagnosing and treating COVID-19 are affected by these variants and what possible changes can be implemented are the other questions, which are sought to be answered.
