Background: Hematological parameters, including albumin and hemoglobin (Hb) levels and lymphocyte counts, are low-cost tests that can be used to determine inflammation and nutritional status. Recent studies have shown that inflammation plays a very important role in the development of carcinogenesis. Materials and Methods: The authors aimed to investigate whether preoperative hemoglobin, albumin, lymphocyte, and platelet (HALP) score can distinguish between benign and malignant causes in patients who are admitted to hospital and operated due to acute mechanical intestinal obstruction (AMIO). The patients were divided into two groups etiologically. Group 1 included the AMIO cases, which developed from benign causes, while Group II contained the AMIO cases, which developed as a result of malignancy. HALP score was calculated based on the latest preoperative Hb, albumin, lymphocyte, and platelet values of patients. Results: HALP variable was an independent prognostic factor (p < 0.001) in determining malignancy (odds ratio = 0.91; 95% confidence interval [CI] = 0.882–0.930). Based on the results, when a cutoff value <23.94 was used for HALP score in receiver operating characteristic analysis, sensitivity for determining the malignancy was 85%, while specificity was 78% (Area under the curve [AUC] ± standard error = 0.86 ± 0.029; 95% CI = 0.80–0.91; p < 0.001). Conclusions: The HALP score could be a useful parameter for the clinician in distinguishing between AMIO due to benign and malignant origins.

BACKGROUND: Acute appendicitis (AA) is the most common extra-obstetric condition requiring surgery during pregnancy. AA diagnosis is made by laboratory tests along with anamnesis and physical examination findings. Due to the physiological and anatomical changes during the pregnancy, AA diagnosis is more challenging in pregnant women compared to non-pregnant patients. The present study evaluated the significance of white blood cell counts (WBC), neutrophil-to-lymphocyte ratio (NLR), C-reactive protein/albumin ratio (CAR) and lymphocyte-to-C-reactive protein ratio (LCR) to diagnose acute appendicitis during pregnancy. METHODS: Pregnant patients admitted to General Surgery Inpatient Clinic with AA pre-diagnosis in September 2015-December 2019 period were screened using International Statistical Classification of Diseases and Related Health Problems-10 (ICD-10) diagnosis code (K35= acute appendicitis, Z33= pregnancy), and AA patients were identified retrospectively. The patients were divided into two groups. The Group I included the patients who had appendectomy due to AA and had a suppurative appendicitis diagnosis based on the pathological evaluation. On the other hand, Group II had the patients admitted as an inpatient with AA pre-diagnosis, but discharged from the hospital with full recovery without operation. Group III, i.e., the control group, on the other hand, was constituted by 32 randomly and prospectively recruited healthy pregnant women who were willing to participate in the study and who had matching study criteria among the patients followed in Obstetrics and Gynecology outpatient clinic of our hospital. RESULTS: This study included 96 pregnant women with an average age of 29.20 +/- 4.47 years (32 healthy pregnant women, 32 pregnant women followed for acute abdominal observation and 32 pregnant women who underwent appendectomy). Of these patients, three cases who turned out not to have suppurative appendicitis (negative appendectomy) and two cases found to have perforated appendicitis based on intraoperative and histopathological evaluations were excluded from this study. The results showed that Group I patients had significantly higher WBC (p=0.001), CAR (p=0.001) and NLR (p=0.001), but significantly lower LCR values (p=0.001) compared to the Groups II and III. Besides, based on logistic regression analysis, it was revealed that higher WBC, CAR and NLR values and lower LCR values were independent variables that could be used for the diagnosis of AA in pregnant women. CONCLUSION: Considering WBC, NLR, CAR and LCR parameters in addition to medical history, physical examination and imaging techniques could help clinicians diagnose acute appendicitis in pregnant women.

Background. Early diagnosis of gastric cancer is one of the most important parameters affecting the survival of the disease. In this study, we aimed to stress the importance of antrum wall thickness in CT examination.Method. The study included 111 patients between ages of 18 and 95 who had antral wall thickening in computed tomography and also had endoscopic evaluation performed in the same clinic. The patients were divided into two groups as benign and malignant according to the pathology results. The thickness of the antrum wall in computed tomography, hemoglobin and albumin levels, and age was compared among these two groups. Parameters with significant differences were further analyzed by multivariate analysis using logistic regression analysis.Results. Of the 111 patients included in the study, 57 were male and 54 were female. Mean age was 65 years. Fifty-one patients were classified as benign and 60 patients as malignant. Mean age of the malignant patients was 70, while that of benign patients was 59 (p<0.05). Antrum wall thickness was 13.68 ± 3.27 mm in malignant patients and 9.22 ± 2.17 mm in benign patients (p<0.05). Similarly, hemoglobin level was significantly different in malignant and benign patients (10.78 ± 1.57 g/dl and 12.64 ± 1.43 g/dl, respectively;p<0.05). Albumin levels were 3.36 ± 0.57 mg/dl in malignant patients and 3.97 ± 0.57 mg/dl in benign patients (p<0.05).Conclusion. Evaluation of antrum wall thickness, age, hemoglobin, and albumin values together may contribute to distinguishing the benign and malignant pathologies involving this region in patients with suspected stomach wall thickening in abdominal CT scan.

Aim/Background. Early diagnosis of patients with colon cancer is one of the most important parameters affecting the survival of patients. In this study, we aimed to examine the effect of the age, hemoglobin (Hb), albumin, neutrophil lymphocyte ratio (NLR), thrombocyte lymphocyte ratio (PLR), and mean platelet values (MPV) on the separation of benign and malignant diseases in patients with suspected colon wall thickness (CWT) observed in abdominal computed tomography (CT) examination. Method. The study included 116 patients between the ages of 18 and 95 who had CT examination where the colon wall could be evaluated and who also had colonoscopy. Patients suspected for CWT in CT with difficulties in differential diagnosis were divided into two groups according to colonoscopic-histopathological evaluations. Normal or benign pathological causes were included in the first group, while malignant causes constituted the second group. Whether the two groups differed in terms of CWT, Hb, age, albumin, NLR, PLR, and MPV values was investigated with descriptive statistics. Results. One hundred and sixteen patients (74 males, 42 females) with CT examinations and colonoscopic sampling were included in the study. After colonoscopic and histopathological evaluations, there were 64 cases in the first group and 52 in the second group. According to the results of the univariate analysis and multivariate logistic regression, CWT, Hb, NLR, and MPV were identified to be independent variables for determining colon cancer. Conclusion. A combined evaluation of Hb, NLR, and MPV values in patients with CWT in abdominal CT examination may contribute to the separation of benign and malignant pathologies.
