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.

Henoch-Schönlein Purpura Presenting with Acute Abdomen.

Henoch-Schönlein Purpura (HSP) is an autoimmune, systemic, non-granulomatous vasculitis characterised by self-limiting clinical course, and leukocytoclastic vasculitis of small vessels. Deposition of immune complexes that contain IgA is the hallmark of vascular involvement. Adults with HSP have a higher incidence of complications and death. The most common gastrointestinal (GI) symptom of HSP is abdominal pain. Vasculitis-related colitis, causing extensive lower GI hemorrhage, is uncommon in the course of HSP, which increases the risk of renal involvement. Here, we present two cases of HSP with GI involvement. In the first case, surgery was performed.  Whereas, the other patient was treated medically due to the experience gained from the first case. The HSP has no specific treatment. Most of the cases are mild and need only supportive care due to its self-limiting nature. Although corticosteroids do not prevent recurrences, evidence in literature suggests that these are beneficial in resolution of the arthritis and abdominal pain. Aggressive therapy with corticosteroids or cyclophosphamide is not successful in reducing renal damage, except in patients with crescentic nephritis. Key Words: Henoch-Schönlein purpura, Gastrointestinal complications, Steroids, Surgery.

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.

Prediction of Lymph Node Metastasis in Colon Cancer via Platelet to Lymphocyte Ratio and Platelet Count.

OBJECTIVE: To investigate the value of preoperative blood tests in predicting lymph node metastasis in colon cancer patients undergoing surgery. STUDY DESIGN: Obervational study. PLACE AND DURATION OF STUDY: General Surgery Department, Bolu Abant Izzet Baysal University Medicine School, Turkey, between December 2012 and December 2018. METHODOLOGY: In 171 colon cancer patients, preoperative inflammatory markers such as albumin, C-reactive protein (CRP), platelet, neutrophil-to-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR) counts were determined. RESULTS: The present study albumin, CRP and NLR values were also not significantly different between the groups. PLR (p=0.008) and PLT (p=0.039) were significantly different between the lymph node groups. ROC analysis was performed for PLT and PLR for the prediction of lymph node metastasis (Group 2 and 3). Accuracy for PLT was 0.623 and accuracy for PLR was 0.65. A PLT value >321.5 was found to be 63.7% sensitive and 68.6% specific in predicting lymph node metastasis. A PLR value >155.81 was 70% sensitive and 41% specific for predicting lymph node metastasis. CONCLUSION: The platelet counts and PLR values are important in predicting lymph node metastasis in colon cancer, preoperatively. Platelet and PLR values may be more specific and sensitive in predicting preoperative lymph node metastasis in colon cancer patients.

The relationship between tumor budding and survival in colorectal carcinomas.

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.

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 Effects of Early Enteral Nutrition Products on the Healing of Colo-Colonic Anastomosis.

OBJECTIVES: Complications after colorectal surgery have not been reduced in recent years. Anastomotic leakage is responsible for nearly all morbidity in colonic surgery and for about one third of the mortality. MATERIAL AND METHODS: For the study, 34 albino Wistar rats (about 155-190 g in weight) were divided into four experimental groups. Each of the rats underwent an abdominal incision and resection of the colon 4 cm distal to the cecum to form a colo-colonic anastomosis. In the post-operative period, the first group (n=8) were fed with standard rat food and water, the second group (n=9) with dextrose+Ringer solution, the third group (n=9) with Biosorb® (Nutricia, Zoetermeer, The Netherlands), and the fourth group (n=8) with Impact® (Novartis Nutrition, USA). RESULTS: The blow-out pressure of the anastomoses was significantly different in the group fed 5% dextrose+Ringer solution group than in the Biosorb® and Impact® groups. CONCLUSIONS: None of the various nutrients investigated in the present study were significantly superior to standard foods in terms of the blow-out pressures. On the other hand, immunonutrients were more beneficial effects than other nutrients in terms of the healing of colonic anastomoses and post-operative weight loss.

Risk factors for operative mortality and morbidity in gastric cancer undergoing D2-gastrectomy.

AIM: We have assessed the risk factors for mortality and morbidity subsequent to D2-gastrectomy in gastric cancer cases. PATIENTS AND METHOD: The records (age, gender, comorbidity, ASA score, POSSUM score, type of gastrectomy, additional organ resection and pathologic TNM stage) were reviewed in 49 cases of D2 gastrectomies (between 2003 and 2008) retrospectively. RESULTS: Mean age was 60.4 (range: 35-82). The factors of comorbidity (n=38) in 27 patients. The average quantity of lymph nodes was 21.2 (range: 16-31) in D2 dissections. The rate of mortality was 8.2% (4/49). All the patients who died had major comorbid diseases and all were submitted to total gastrectomy. Twenty-one morbidities were detected in 13 patients [morbidity rate was 26.5% (13/49)]. We have observed a nearly statistically significant (p=0.074) disadvantage of total gastrectomy versus subtotal gastrectomy [those who died had undergone total gastrectomy, and the morbidity rates were 36.4% vs 14.8%] in concordance with literature. CONCLUSION: In these studies, we have observed that our mortality (8.2%) and morbidity (26.5%) rates are in concordance with the data from medical literature, and POSSUM scores are the only parameter in positive statistical correlation with mortality. Preoperative and postoperative resuscitation are of great importance if the patients have POSSUM score >20.
