Evaluation of the American College of Radiology Thyroid Imaging, Reporting and Data System (Thyroid imaging reporting) scoring in thyroid Bethesda category on atypia and follicular lesion of uncertain significance patients.

OBJECTIVE: Treatment and follow-up are controversial in patients whose thyroid fine needle aspiration biopsy (FNAB) is reported as atypia of undetermined significance and follicular lesion of uncertain significance (AUS/FLUS). We aimed the efficacy of the American College of Radiology Thyroid Imaging, Reporting and Data System (ACR TI-RADS) in preventing unnecessary thyroidectomies in patients with FNA cytology results as AUS/FLUS. METHODS: In Bolu Abant Izzet Baysal University General Surgery Clinic, case series between 2017 and 2020 were analyzed with thyroid operated. Grouping was made according to the result of postoperative pathology: those with benign results after postoperative pathology were classified as Group 1, and those with malignant results after postoperative pathology were classified as Group 2. RESULTS: As a result, 66 patients were found to be AUS/FLUS. A total of 28.8% of AUS/FLUS patients have been determined with cancer. In the statistical analysis of the ACR TI-RADS score between the groups, the ACR TI-RADS score in Group 1 patients (3.36) (SD 0.87) was significantly lower than that in Group 2 patients (4.11) (SD 1.04) (p=0.003). The distribution of the ACR TI-RADS scores of the patients in Group 2 was TR2: 2 (15.4%) patients, TR3: 3 (25%) patients, TR4: 5 (16.1%), TR5: 9 (90%) patients, respectively. CONCLUSION: The ACR TI-RADS score was statistically significant in predicting malignancy in AUS/FLUS patients whose follow-ups and treatments are controversial, and the ACR TI-RADS has a limited role in preventing unnecessary thyroidectomies in patients with AUS/FLUS.

Is appendectomy a simple surgical procedure?

OBJETIVO: La apendicitis aguda es uno de los procedimientos quirúrgicos más aplicados en todo el mundo. Una de las complicaciones de la apendicectomía es la apendicitis del muñón. El diagnóstico de apendicitis del muñón suele retrasarse. MÉTODOS: En nuestro estudio recopilamos casos de apendicitis del muñón tras apendicectomía. Todos los casos con apendicectomía abierta y laparoscópica fueron incluidos en nuestro estudio. RESULTADOS: Entre 2008 y 2020 se examinaron 5620 pacientes apendicectomizados que fueron operados en la clínica de cirugía general. Se realizó apendicectomía en 5 pacientes por apendicitis del muñón. Uno de los pacientes con apendicitis del muñón presentó síntomas de peritonitis generalizada, otro con síntomas de íleo, el otro con síntomas de hernia de incisión encarcelada en la incisión de Mc Burney y los otros dos pacientes con síntomas de apendicitis aguda. CONCLUSIONES: Como se desprende de nuestro estudio, si bien la apendicectomía es el procedimiento quirúrgico más común y fácil de ver en la práctica quirúrgica general, es un procedimiento que aumenta la morbilidad como vemos en los pacientes con apendicitis del muñón. La tomografía abdominal parece ser el estándar de oro en el diagnóstico de la apendicitis del muñón. Los cirujanos definitivamente deben sospechar apendicitis del muñón en pacientes cuyos síntomas han mejorado, incluso con cicatrices de apendicectomía abierta. OBJECTIVE: Acute appendicitis is among the most applied surgical procedures around the world. One of the complications of appendectomy is stump appendicitis. The diagnosis of stump appendicitis is usually delayed. MATERIAL AND METHOD: In our study, we compiled cases with stump appendicitis after appendectomy. All cases with open and laparoscopic appendectomy were included in our study. RESULTS: Between 2008 and 2020, 5620 appendectomy patients who were operated in the general surgery clinic were examined. Appendectomy was performed in five patients due to stump appendicitis. One of the patients with stump appendicitis presented with symptoms of generalized peritonitis, another with symptoms of ileus, the other with symptoms of incarcerated incision hernia at the McBurney incision, and the other two patients with symptoms of acute appendicitis. CONCLUSION: As it can be understood from our study, although appendectomy is the most common and easily seen surgical procedure in general surgical practice, it is a procedure that increases morbidity as we see in patients with stump appendicitis. Abdominal tomography appears to be the gold standard in diagnosis in stump appendicitis. Surgeons should definitely suspect stump appendicitis in patients whose symptoms have improved, even with open appendectomy scarring.

Ibuprofen increases the serum Omentin levels in rats after abdominal surgery.

AIMS Omentin is an adipokine primarily produced by visceral adipose tissue and its reduced levels have been shown to be associate with worse metabolic outcomes. We aimed to study the effects of preoperative ibuprofen on postoperative omentin levels in rats after surgery. METHODS Forty-eight albino Wistar rats, 6 in each of 8 groups according to the surgical procedure (laparotomy, laparotomy plus ibuprofen (IBU), nephrectomy, nephrectomy plus IBU, hepatectomy, hepatectomy plus IBU, splenectomy and splenectomy plus IBU). The Omentin levels of the groups were postoperatively analyzed. RESULTS The mean omentin was significantly higher in the laparotomy plus IBU group compared to the laparotomy group (p<0.001). Mean Omentin was significantly higher in the hepatectomy plus IBU group compared to the hepatectomy group (p=0.01). Mean Omentin was significantly higher in the nephrectomy plus IBU group compared to the nephrectomy group (p=0.001). CONCLUSION We suggest that preoperative ibuprofen may enhance circulating levels of Omentin, which has beneficial effects in trauma and inflammation settings in subjects that undergo minor or major abdominal surgery.

RESUMO OBJETIVOS A omentina é uma adipocina produzida principalmente pelo tecido adiposo visceral e níveis reduzidos dela foram associados a piores desfechos metabólicos. Nosso objetivo foi estudar os efeitos do uso pré-operatório do ibuprofeno nos níveis pós-operatórios da omentina em ratos. METODOLOGIA Quarenta e oito ratos Wistar albinos foram divididos em 8 grupos (6 em cada), de acordo com o procedimento cirúrgico: laparotomia, laparotomia e ibuprofeno (IBU), nefrectomia, nefrectomia e IBU, hepatectomia, hepatectomia e IBU, esplenectomia, e esplenectomia e IBU. Os níveis de omentina dos grupos foram analisados após a cirurgia. RESULTADOS A omentina média foi significativamente maior no grupo de laparotomia e IBU do que no grupo de laparotomia (p<0,001). A omentina média foi significativamente maior no grupo de hepatectomia e IBU do que no grupo de hepatectomia (p = 0,01). A omentina média foi significativamente maior no grupo de nefrectomia e IBU do que no grupo de nefrectomia (p = 0,001). CONCLUSÃO Sugerimos que o uso pré-operatório de ibuprofeno pode aumentar os níveis circulantes de omentina, que têm efeitos benéficos em um contexto de trauma e inflamação em indivíduos submetidos cirurgia abdominal.

The relationship between tumor budding and survival in colorectal carcinomas

SUMMARY OBJECTIVE Tumor budding is a parameter that is increasingly understood in colorectal carcinomas. We aimed to investigate the relationship between tumor budding, prognostic factors, and survival METHODS A total of 185 patients who had undergone colorectal surgery were observed. Tumor budding, the tumor budding score, and the relationship between these and prognostic factors, and survival investigated. RESULTS Tumor budding was found in 91 (49.2%) cases. The relationship between the tumor budding score and histological grade, lymphovascular invasion, perineural invasion, pathological lymph node stage, and mortality rates were significant. CONCLUSION In our study, the relationship between tumor budding and survival is very strong. Considering these findings and the literature, the prognostic significance of tumor budding becomes clear and should be stated in pathology reports.

Neutrophil to Lymphocyte Ratio is Useful in Differentiation of Malign and Benign Thyroid Nodules.

OBJECTIVE: Significant amount of thyroid nodules are malignant. Inflammation plays crucial role in the pathogenesis of many disorders, including cancer. Neutrophil to lymphocyte ratio (NLR), has been suggested as an index of inflammatory response and association between increased NLR and cancer has also been reported. In this retrospective analysis, we aimed to study NLR levels in patients with malign and benign thyroid nodules and healthy control subjects. METHODS: The patients who underwent surgery for nodular goiter in general surgery clinics of our university hospital between June 2012 and June 2015 and 68 healthy volunteers were included. Patients with thyroid nodules divided into malign or benign nodule groups according to the pathology report. Thyroid carcinomas other than micropapillary tumor were excluded. Preoperative hemogram parameters of these groups were compared. RESULTS: Mean NLR of malign nodule group (2.1±0.9%) was significantly higher than both those in benign nodule (1.7±0.9%) and control groups (1.7±0.6%). CONCLUSION: We suggest that elevated NLR in patients with thyroid nodules in preoperative period may be an indicator of underlying malign nodular disease. Increased NLR in such patients should encourage physician to perform cancer screening in thyroid gland.

Elevated neutrophil-to-lymphocyte ratio in the diagnosis of Hashimoto's thyroiditis

Summary Objective: Hashimoto's thyroiditis (HT) is an autoimmune inflammatory disorder. The purpose of this study was to determine the neutrophil-to-lymphocyte ratio (NLR), a novel marker of inflammation, in patients with HT and to compare these values with those from healthy subjects. Method: A total of 154 participants were included in the study, 90 HT patients and 64 healthy volunteers. Retrospectively, demographic and laboratory data of the subjects were obtained from our institution's database. Patients with active infection, diabetes mellitus, malignancy, other chronic inflammatory diseases, hematologic disorders and patients on aspirin or steroid treatment were excluded from the study. Values for complete blood count (CBC) and serum laboratory parameters of HT patients were the baseline values obtained at the time of HT diagnosis. Control subjects consisted of healthy volunteers who visited our institution for a routine check-up. Results: Age, gender and CBC parameters were not different between the HT group and the control group; however, the NLR of HT group (2.1 [1.3-5.8]) was significantly higher than the control group (1.9 [0.6-3.3]), p=0.04. Conclusion: Increased NLR may be useful as an indicator of the presence of HT, especially in complicated cases. NLR is inexpensive and easy to determine. Larger, prospective studies are required to determine its usefulness in assessing diagnostic potential and treatment outcomes in HT patients.
