COVID-19 outbreak and acute appendicitis: Does the lockdown has a influence on appendectomies?-A single center retrospective cohort study.

Objectives: Healthcare systems have been negatively affected from COVID-19 pandemic worldwide. Elective surgical procedures were postponed and conservative treatment options were considered even in urgent conditions. This study aimed to explore the influence of the COVID-19 pandemic on urgent appendectomy in a pandemic hospital. Material and Methods: Patients on whom appendectomy was performed between March 2020- June 2020 were included into the study (pandemic group). For comparison, control group patients were selected in the same period of 2019 (control group). Patients' demographics, laboratory and radiological findings, length of hospital stay, complications and histopathological findings of the groups were compared. Results: Forty-six patients were included in pandemic group and and one hundred-one in the control group. Patient characteristics were similar in both groups. There were no significant differences in type of surgery, complications, laboratory and histopathological findings. In the control group, length of hospital stay was longer when compared with the pandemic group. Conclusion: Although the number of appendectomies performed decreased significantly during the COVID-19 pandemic, perioperative parameters were similar in both groups.

Risk Factors and the Role of the Albumin-to-Globulin Ratio in Predicting Recurrence Among Patients with Idiopathic Granulomatous Mastitis.

Background: Idiopathic granulomatous mastitis (IGM) is a rare inflammatory disease of the breast with a high recurrence rate. The serum albumin to globulin ratio (AGR) is a relatively novel biomarker in inflammatory diseases, and one whose role in the recurrence of IGM remains unknown. This study primarily investigated the potential risk factors for IGM recurrence and whether AGR can be used as a predictive factor. Methods: Patients diagnosed with IGM from pathology reports between 2016 and 2021 were enrolled in the study, and their medical records were analyzed retrospectively. The patients were divided into two groups - recurrence and non-recurrence. Clinical, demographic characteristics, and laboratory parameters were compared. Results: Eighty-five patients were included in the study, recurrence being detected in 16 (18.8%) of these, with a median follow-up time of 39.99±18.93 months. No relationship was determined between childbearing, breastfeeding, disease severity, or therapeutic approaches and IGM recurrence. While AGR was significantly lower in the recurrence group (p < 0.001), neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) results were comparable in the two groups (p = 0.472 and p = 0.421, respectively). Multivariate analysis identified low AGR (odds ratio (OR): 50.7, 95% CI 5.93-434.1 P < 0.001) and smoking (OR: 4.45, 95% CI 1.04-18.9 P = 0.044) as independent risk factors for IGM recurrence. Conclusion: The study findings indicated that AGR at a cut-off value of ≤1.179 at diagnosis and smoking exhibited a remarkable performance in predicting the recurrence of IGM. Developing new risk stratification systems for IGM recurrences and using AGR in these classifications may increase the success of treatment. Trial Registration: This study was registered with ClinicalTrials.gov, NCT05409586.

Acute Biliary Pancreatitis Management during the Coronavirus Disease 2019 Pandemic.

(1) Objective: We aimed to analyze and describe the management of acute biliary pancreatitis (ABP) during the coronavirus disease 2019 (COVID-19) pandemic. (2) Methods: This was a retrospective cohort study among patients with ABP during a control period (16 March 2019 to 15 March 2020; period 1) and a COVID-19 period (16 March 2020 to 15 March 2021; period 2). (3) Results: We included 89 patients with ABP, being 58 in period 1 and 31 in period 2. The mean patient age was 62.75 ± 16.59 years, and 51 (57.3%) patients were women. The Quick Sequential Organ Failure Assessment score for sepsis and World Society of Emergency Surgery Sepsis Severity Score were significantly higher among patients in period 2. Twenty-two patients (37.9%) in period 1 and six (19.3%) in period 2 underwent cholecystectomy. There were no significant differences in surgical interventions between the two periods. The hospital mortality rate was 3.4 and 19.3% in period 1 and period 2, respectively. Mortality was significantly higher in period 2. Conclusion: During the COVID-19 pandemic, we observed a significant reduction in the number of patients with ABP but increased severity and mortality. Multicenter studies with more patients are needed to obtain additional evidence regarding ABP management during the COVID-19 pandemic.

Characteristics and surgical outcomes of patients with atraumatic splenic rupture.

OBJECTIVE: Although rare, late-diagnosed atraumatic splenic rupture (ASR) may result in mortality. We investigated the occurrence of ASR cases at our centre over the previous six years. METHODS: This was a retrospective, cross-sectional study that included all patients who underwent emergency splenectomy due to ASR between January 01, 2015, and January 01, 2021. RESULTS: Of the 203 patients who underwent splenectomy, 15 met our criteria for ASR. Median age was 55 years (34-90), and 10 (67%) patients were male. Most common pre-existing diseases were diabetes mellitus (6, 40%) and heart valve disease (5, 33%). Ten (67%) patients had splenic rupture due to splenic infarction and abscess. There were two (13%) cases with diffuse large B cell lymphoma (DLBCL) and two (13%) cases with lung cancer and spleen metastasis. Median length of hospital stay was 6 days (2-24) and three (20%) patients died in hospital. CONCLUSIONS: Male sex, previous splenic infarctions, haematological malignancies, lung cancer spleen metastases, underlying cardiovascular disease and diabetes mellitus may increase the risk for ASR. Further prospective controlled studies are needed to confirm our results.

Injury Mechanism, Volume, and Severity of General Surgical Trauma Patients During COVID-19 Lockdown.

Background After the declaration of the COVID-19 pandemic, countries have taken many restriction measures to reduce the spread of the virus and ensure the health system's proper functioning. Our knowledge about the general surgery trauma patients being affected by the restrictions is very limited. Objective To examine the association of the lockdown measurements during the COVID-19 pandemic with general surgical trauma patients' volume and severity at a university teaching hospital. Methods All patients admitted to the emergency department because of trauma and evaluated by the general surgery team were examined in two groups. The COVID-19 restrictions period (17 March 2020 - 31 May 2020) and the corresponding time last year (17 March 2019 - 31 May 2019). Demographic properties, injury mechanisms, emergency trauma scores (ETS), hospital length of stays (HLOS), intensive care unit (ICU) admission rates, surgical interventions, and mortality were compared. Results The number of patients in the restrictions period is 30% lower than the before COVID-19 cohort. ETS was significantly higher in the restrictions period compared to the previous year, whereas no significant difference was detected in terms of injury mechanisms between the groups (p=0.001 vs p=0.493, respectively). HLOS was found to be higher in the restrictions period (p=0.038). Conclusions Although there was a decrease in the number of general surgical trauma admissions, a significant increase in the severity of trauma was observed during COVID-19 restrictions. We hope these findings will help authorities to guide resource allocation in future pandemic waves.

Synthetic mesh placement in the presence of abdominal infection: An experimental study of feasibility.

BACKGROUND: There are varying opinions on the feasibility of the placement of synthetic materials in contaminated surgical fields. The aim of this study was to investigate the outcomes of the use of a commercially available composite mesh in the presence of abdominal infection. METHODS: Twenty-four hours after the induction of experimental peritonitis, 20 rats were randomized into 2 groups of 10 subjects. After abdominal cleansing with a second laparotomy, the abdomen was closed with running sutures in the control group and the composite mesh was applied in the experimental group before closure. The rats were followed up for findings of sepsis, mortality, and wound infection. On the 28th day, the rats were sacrificed and evaluated for abdominal infection, abdominal adhesions, and bacterial growth in the mesh and tissue cultures. RESULTS: The mortality rate was 0% and 30% in the control and mesh groups, respectively (p=0.21), and the wound infection rate was 20% and 57.1% (p=0.162). In the mesh group, the adhesions were significantly more intense (p=0.018) and significantly more microorganisms proliferated in the tissue cultures (p=0.003). CONCLUSION: The significant increase in the intensity of adhesions and bacterial proliferation, as well as the higher rate of mortality and wound infection in the mesh group indicated that this composite mesh cannot be used safely in the repair of abdominal defects in the presence of abdominal infection.

Early versus delayed laparoscopic cholecystectomy for acute cholecystitis: a prospective, randomized study.

We aimed to compare the clinical outcome and cost of early versus delayed laparoscopic cholecystectomy for acute cholecystitis. Sixty patients with acute cholecystitis were randomized into early (within 24 hours of admission) or delayed (after 6-8 weeks of conservative treatment) laparoscopic cholecystectomy groups. There was no significant difference between study groups in terms of operation time and rates for conversion to open cholecystectomy. On the other hand, total hospital stay was longer (5.2 ± 1.40 versus 7.8 ± 1.65 days; P = 0.04) and total costs were higher (2500.97 ± 755.265 versus 3713.47 ± 517.331 Turkish Lira; P = 0.03) in the delayed laparoscopic cholecystectomy group. Intraoperative and postoperative complications were recorded in 8 patients in the early laparoscopic cholecystectomy group, whereas no complications occurred in the delayed laparoscopic cholecystectomy group (P = 0.002). Despite intraoperative and postoperative complications being associated more with early laparoscopic cholecystectomy compared with delayed intervention, early laparoscopic cholecystectomy should be preferred for treatment of acute cholecystitis because of its advantages of shorter hospital stay and lower cost.

Non-recurrent laryngeal nerve.

Injury to the recurrent laryngeal nerve is a serious complication in thyroid and parathyroid surgery. The anatomy of the recurrent laryngeal nerve is variable. Non-recurrent nerve is a very rare variation of the inferior laryngeal nerve. Because of the anatomical variations of the nerve, preservation of the nerve is the optimal strategy during surgery. In this case report, we present a non-recurrent laryngeal nerve abnormality in a patient who underwent parathyroidectomy, thyroidectomy and functional neck dissection for malignant parathyroid disease. A non-recurrent laryngeal nerve was identified during nerve exploration.
