A study to assess the awareness of risk factors of cystic echinococcosis in Turkey.

OBJECTIVES: To determine the knowledge, attitudes, practices, and awareness for risk factors associated with cystic echinococcosis (CE) among animal breeders, nurses, nursing students, dietitians, food professionals and other public groups in Turkey. Methods: Questionnaire forms were prepared in compliance with the individuals' diversity, and a survey was created about agents, transmission modes, epidemiology, treatment, and risk factors for CE. The descriptive survey was performed between May 2015 and May 2016 by face-to-face communication. Data were collected from a total of 647 individuals, including 95 animal breeders, 92 nurses, 249 nursing students, 49 dietitians, 28 food professionals and 134 people from other public groups from Turkey. Survey data were evaluated in terms of percentages and means and analyzed by the Pearson's chi-square test and Mann-Whitney U test to determine the relationships between questionnaire answers and socio-demographic attributes, such as age, gender, educational level, and profession. Non-categorical variables were compared via Spearman's rho correlation analysis with statistical significance set at the 0.05 level. Results: We determined low awareness for vegetable washing, raw vegetables and offal consumption, informative courses, contact with dogs, and administration of antiparasitic drugs to dogs. Conclusion: The participants of this survey were found to be with insufficient knowledge regarding risk factors of CE. We advocate the implementation of training programs to improve public awareness on this important disease.

Neutrophil to Lymphocyte Ratio on Appendectomy of Geriatric and Nongeriatric Patients.

PURPOSE: Acute appendicitis is the most frequent emergency procedure that requires acute surgical intervention. The mortality risk is higher in geriatric patients. There is not a single parameter to diagnose it easily and negative appendectomy is traditionally accepted however the operation itself can cause morbidity and mortality especially in elderly patients. The neutrophil-to-lymphocyte ratio is a predictor of acute inflammation and was recently studied for the diagnosis of AA. The aim of this study is to analyze the diagnostic value of NLR on positive appendectomy rates amongst geriatric and nongeriatric patients. MATERIALS AND METHODS: 755 patients admitted to the emergency department, with abdominal pain who underwent urgent laparotomy after diagnosed as acute appendicitis. Patients' ages, genders, laboratory results, and intraoperative findings were collected. Geriatric patients were analyzed in group one, and nongeriatric patients were in group 2. Groups then sorted into subgroups by means of positive and negative appendectomies. RESULTS: Although NLR was higher in positive appendectomy subgroup in group 1 it was not statistically significant. NLR could not independently predict positive appendectomy in geriatric patients. In group 2, male gender was significantly higher in the positive appendectomy group (p < 0.001). NLR was also significantly higher in the positive appendectomy group (p < 0.001). In group 2 NLR could independently predict positive appendectomy (p < 0.001). CONCLUSION: NLR could not predict positive appendectomy rates in the geriatric population but could in the nongeriatric patient group. To find the optimal NLR levels, prospective randomized studies are needed.

Sentinel Lymph Node Detection by 3D Freehand Single-Photon Emission Computed Tomography in Early Stage Breast Cancer.

We herein present our first experience obtained by 3D freehand single-photon emission computed tomography (SPECT) (F-SPECT) guidance for sentinel lymph node detection (SLND) in two patients with early stage breast cancer. F-SPECT guidance was carried out using one-day protocol in one case and by the two-day protocol in the other one. SLND was performed successfully in both patients. Histopathologic evaluation showed that the excised nodes were tumor negative. Thus, patients underwent breast-conserving surgery alone.

High levels of platelet/lymphocyte ratio are associated with metastatic gastric cancer.

PURPOSE: The predictive and prognostic value of cheap, easily accessible and commonly available complete blood count parameters has already been studied in a variety of cancers. In the present study, we aimed to investigate the association between pretreatment platelet/lymphocyte ratio (PLR) and metastatic gastric cancer. METHODS: The records of 228 patients dating from January 2010 to June 2014 were retrospectively evaluated. Patients who had undergone radical (N=157) or palliative gastrectomy (N=71) for metastatic gastric cancer were included and divided into two groups according to stage (early-advanced) and metastasis (absence-presence) status, and PLR values were compared. RESULTS: 38 (16.6%) of 228 patients had early gastric cancer (non metastatic cases). PLR values of advanced gastric cancer (not including metastatic cases) were significantly higher compared to early gastric cancer (231.6±107.45 and 160.3±71.5, respectively; p<0.001). Seventy one (31.1%) of 228 patients had distant metastasis. PLR values of metastatic gastric cancer were significantly higher than in non-metastatic gastric cancer (251.0±94.8 and 192.7±88.8, respectively; p<0.001). Logistic regression analysis showed that PLR was an independent predictive factor for tumor burden in both stage and metastasis groups (p<0.001 and p=0.003, respectively). Also, in correlation analysis, PLR showed mild correlation with stage and metastasis groups (r=0.291 and r=0.299, respectively). CONCLUSIONS: Pretreatment PLR values were correlated with tumor burden, and most higher values were detected in metastatic disease. Our findings may be useful, especially in the decision-making for laparoscopic staging in patients who have no radiological evidence of metastatic disease.

Are fibrinogen and complete blood count parameters predictive in incarcerated abdominal hernia repair?

Therapeutic delays in cases of external incarcerated hernias typically result in increasing morbidity, mortality, and health expenditures. We investigated the diagnostic role of blood fibrinogen level, white blood count (WBC), mean platelet volume (MPV), and platelet distribution width (PDW) in patients with incarcerated hernia. Two groups, each containing 100 patients, were studied. Group A underwent elective, and group B underwent incarcerated and urgent external hernia repair. We observed high fibrinogen and WBC levels but low MPV and PDW values for patients in group B. Contrary to our expectations, we found lower MPV and PDW values in the complicated group than in the elective group. The morbidity rate and cost burden were higher in group B, and the results were statistically significant. Early operation should be recommended for patients with incarcerated external hernias if their fibrinogen and WBC levels are high.

Peptic ulcer complications requiring surgery: what has changed in the last 50 years in Turkey.

BACKGROUND/AIMS: The incidence and prevalence of peptic ulcer disease has decreased in recent years, but it is not so easy to make the same conclusion when complications of peptic ulcer are taken into consideration. The aim of this study is to determine the time trends in complicated peptic ulcer disease and to state the effects of H2 receptor blockers, proton pump inhibitors (PPI), and H. pylori eradication therapies on these complications. MATERIALS AND METHODS: This study retrospectively evaluated the patients who were operated on for complications (perforation, bleeding, and obstruction) of peptic ulcer for the last 50 years. Patients were grouped into four groups (G1-G4) according to the dates in which H2 receptor blockers, PPIs, and eradication regimens for H. pylori were introduced The time periods that were studied were: (G1) 1962-1980, (G2) 1981-1990, (G3) 1991-1997, and (G4) 1998-2012. RESULTS: In total, 2953 patients were operated on for complications of peptic ulcer disease, of which 86% of the patients were male. In G1, perforation and obstruction were significantly the most frequent complications (p<0.001), followed by bleeding. In groups G2 and G3, obstruction was still the most frequent complication requiring surgery (p<0.001). In G2 and G3, obstruction was followed by perforation and bleeding, respectively. In G4, perforation was significantly the most frequent complication (p<0.001). CONCLUSION: From 1962 to 1990 obstruction was the most common complication requiring surgery. In the last decade, perforation became the most common complication. In contrast to reports in the literature, bleeding was the least common complication requiring surgery in Turkey.

Effects of intraabdominal pressure on mean platelet volume during laparoscopic cholecystectomy.

BACKGROUND/AIM: Intraabdominal hypertension is a common occurrence, especially in intensive care unit patients, and it has high mortality and morbidity rates. The onset is commonly insidious and the poor prognosis is attributed to the long delay in diagnosis. Unfortunately, diagnosis is often delayed until loss of function in the affected tissues has already occurred. The aim of this study was to determine the predictive value of mean platelet volume (MPV) in assessing the risk of intraabdominal hypertension. MATERIALS AND METHODS: Pneumoperitoneum during elective laparoscopic cholecystectomy was used as a model for intraabdominal hypertension. The study included 103 patients who met the inclusion criteria. MPV evaluations were made at 3 distinct times during laparoscopic cholecystectomy based on the actual intraabdominal pressure. RESULTS: MPV values during preinsufflation, insufflation, and desufflation were 8.483 fL (range: 6.7 to 11.1), 8.901 fL (range: 6.8 to 11.9), and 8.538 fl (range: 5.8 to 10.9), respectively. A statistically significant increase in MPV values was found during high intraabdominal pressures (P < 0.001). A significant decrease in MPV values was also detected with desufflation (P < 0.001). CONCLUSION: Increasing MPV values may reflect increased intraabdominal pressures, which may have a clinical implementation in intraabdominal hypertension.

Neutrophil-lymphocyte ratio as a predictive factor for tumor staging in colorectal cancer.

BACKGROUND/AIM: In the preoperative period, simple methods to identify the tumor stage of colorectal cancer patients are needed. In recent years, the neutrophil-lymphocyte ratio (NLR) has been used as a predictive parameter for systemic inflammatory response in many different clinical entities. This study aims to determine if the NLR predicts the tumor stage in colorectal cancer patients in the preoperative period. MATERIALS AND METHODS: A total of 206 patients diagnosed with colorectal cancer and admitted for surgical treatment over a 6-year period were identified from a retrospectively maintained database. NLR was calculated from preoperative full blood counts. NLRs were compared with the tumor stages as determined in histopathological reports and scanning tests to determine the extent of metastasis. RESULTS: We found NLRs to be statistically higher in patients with T3 and T4 tumors than in patients with T1 and T2 tumors (mean: 5.261 vs. 4.499, respectively, P = 0.010). Similarly, we found statistically higher NLR values in the N1 and N2 groups than in the NO group (mean: 6.597 vs. 4.501, respectively, P < 0.001). Additionally, NLRs were statistically higher in M1 patients than in MO patients (mean: 8.261 vs. 5.158, respectively, P = 0.004). CONCLUSION: In the preoperative period, NLR was found to be a valuable predictive parameter for tumor staging in patients with colorectal cancer, thus informing us as to the kind of tumor we will meet when we open the abdomen.

The role of general surgery consultations in patient management.

OBJECTIVE: Consultation results of patients who were thought to require a surgical intervention and were evaluated in the General Surgery Department for diagnostic support and treatment, upon detection of pathology in clinical and/or laboratory tests. MATERIAL AND METHODS: In a six-months period, 221 patients were retrospectively analyzed. There were 121 male (54.75%) and 100 female (45.25%) patients and the mean age was 46 years (15-102). The departments which requested consultation, the reason for consultation, test and physical examination findings before consultation, required additional tests after consultation and results of consultations were recorded as well as performed interventions. RESULTS: The majority of consultations were from the emergency department (91.9%) and the most frequent reason was abdominal pain (29.9%). No tests were performed before consultation in 21% of cases. Physical examination was completely fulfilled in 100% of judicial cases, but this ratio was 35% in perianal diseases and 30% in patients with bowel obstruction. Additional tests were required in 54.3% of the patients after consults. Out of the whole group with surgical consultation, 21% were operated under general anesthesia, 9% under local anesthesia, while an elective operation was suggested in 3%. CONCLUSION: Currently, it is mandatory that patient management is carried out with a multidisciplinary approach; however, we believe that consultations should be asked in a more selective manner.

The role of proton MR spectroscopy and apparent diffusion coefficient values in the diagnosis of malignant thyroid nodules: preliminary results.

PURPOSE: Performance of proton magnetic resonance spectroscopy (H-MRS) and apparent diffusion coefficient (ADC) values in the diagnosis of malignant thyroid nodules. METHOD: In a retrospective study with malignant nodules of 14 patients, H-MRS and diffusion-weighted MR imaging (DWI) were performed. Choline (Cho) peak, Cho/creatine (Cr) ratio, and ADC values of malignant nodules were correlated with the five benign nodules and four normal-appearing thyroid lobe parenchymata. The gold standard reference was fine needle aspiration biopsy and histopathology. RESULTS: At echo time 40-144-ms acquisitions, average Cho/Cr ratio for the malignant nodules was 2.95±1.54-5.30±2.38, cutoff values were >0.805 and >1.225, and ADC values were 0.06±0.02. CONCLUSION: H-MRS acquisitions, DWI, and ADC mapping give diagnostic data about the nature of the nodules.

Anomalous opening of the common bile duct into the duodenal bulb: endoscopic treatment.

BACKGROUND: Anomalous biliary opening especially the presence of the ampulla of Vater in the duodenal bulb is a very rare phenomenon. We report clinical implications, laboratory and ERCP findings and also therapeutic approaches in 53 cases. METHODS: The data were collected from the records of 12.158 ERCP. The diagnosis was established as an anomalous opening of the common bile duct (CBD) into the duodenal bulb when there is an orifice observed in the bulb with the absence of a papillary structure at its normal localization and when the CBD is visualized by cholangiography through this orifice without evidence of any other opening. RESULTS: A total of 53 cases were recruited. There was an obvious male preponderance (M/F: 49/4). Demographic data and ERCP findings were available for all, but clinical characteristics and laboratory findings could be obtained from 39 patients with full records. Thirty-seven of 39 cases had abdominal pain (95%) and 23 of them (59%) had cholangitis as well. Elevated AP and GGT were found in 97.4% (52/53). History of cholecystectomy was present in 64% of the cases, recurrent cholangitis in 26% and duodenal ulcer in 45%. Normal papilla was not observed in any of the patients and a cleft-like opening was evident instead. The CBD was hook shaped at the distal part that opens to the duodenal bulb. Pancreatic duct (PD) was opening separately into the bulb in all the cases when it was possible to visualize. Dilated CBD in ERCP was evident in 94% and the CBD stone was demonstrated in 51%. PD was dilated in four of 12 (33%) cases. None of them has a history of pancreatitis. Endoscopically, Papillary Balloon Dilatation instead of Sphincterotomy carried out in 19 of 27 patients (70%) with choledocholithiazis. Remaining eight patients had undergone surgery (30%). Clinical symptoms were resolved with medical treatment in 16(32%) patients with dilated CBD but no stone. Perforation and bleeding were occurred only in two patients, which stones extracted with sphincterotomy (each complication in 1 patient). CONCLUSION: The opening of the CBD into the duodenal bulb is a rare event that may be associated with biliary and gastric/duodenal diseases. To date, surgical treatment has been preferred. In our experience, sphincterotomy has a high risk since it may lead to bleeding and perforation by virtue of the fact that a true papillary structure is absent. However, we performed balloon dilatation of the orifice successfully without any serious complication and suggest this as a safe therapeutic modality.
