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.

Cholecystectomy is one of the most frequently performed surgeries. Although laparoscopy is considered the gold standard approach, it cannot prevent biliary injuries. Subtotal cholecystectomy has been performed mainly to prevent biliary injuries during difficult cholecystectomies. This study aimed to analyse our subtotal cholecystectomy results for difficult cholecystectomy cases and to evaluate the fenestrating and reconstituting techniques. Retrospective data were collected and analysed statistically for cases that underwent subtotal cholecystectomy in a single referral centre between 2015 and 2020. Comparisons were made of the patients’ age, gender, preoperative American Society of Anaesthesiologists (ASA) score, comorbidities, surgical timing, surgical procedure choice, postoperative complications, and mortality. The number of patients who underwent subtotal cholecystectomy was 46; 30.4% underwent emergent surgery and 69.6% underwent elective surgery. Twelve patients had subtotal fenestrating cholecystectomy and 34 had subtotal reconstituting cholecystectomy. Wound issues were noted in 17.4% of the patients, while 10.9% had temporary biliary fistulas that resolved spontaneously. Reoperation was performed in one patient due to high-output biliary drainage. Patients with postoperative complications had significantly higher co-morbid conditions (p=0.000), but surgery timing (p=0.192) and type of subtotal cholecystectomy (p=0.409) had no statistically significant effect on complications. Mortality showed a statistically significant correlation with patient comorbidities, surgery timing, and the type of procedure (p<0.05). Postoperative complications showed a statistically significant correlation with mortality (p<0.05). Subtotal cholecystectomy prevents major biliary complications after cholecystectomy. Yet, the frequency of postoperative complications after subtotal cholecystectomy is incontrovertible. Intraoperative characteristics and the surgeon’s expertise decide the optimal choice of the subtotal cholecystectomy technique.

Aim: Amebiasis is a disease caused by protozoon Entamoeba histolytica, that results in amoebic dysentery. While intestinal parasites are the third leading cause of death, especially in developing countries, it has been of global concern. Bibliometric methods have been used in the parasitology discipline for more than 30 years, however there is not any bibliometric study on amebiasis in the literature. Our aim was to analyse the published literature on amebiasis by bibliometric methods. Material and methods: A systematic evaluation of the literature using the Scopus database was made from inception to 2021. The search terms ‘amebiasis’, ‘Entamoeba’, ‘Entamoeba histolytica’, and ‘amoebic dysentery’ were used. The authors, publication year, title, publishing country/journal/institution, title, keywords, and citation numbers were acquired for each article. Descriptive data analysis was conducted via Microsoft Excel 2010 and Scopus database’s graphics were used. Results: Among 7,140 articles, 18.9 % of them were published open access, and 72.75 % of them were in the English language. Most of the articles were from the area of medicine. The USA, Mexico, and India were the top leading countries. The number of publications did not fall below 50 per year since 1950. There was an increasing number of citations on amebiasis research recently. Conclusion: Amebiasis is a global concern as one of the leading infectious causes of mortality in developing countries. Bibliometric analysis has shown the growing attraction to the amebiasis research, so it will continue to be global public health issue. Key words: amebiasis, bibliometric analysis, Entamoeba histolytica, bibliometrics

Despite the recent increase in the use of laparoscopic appendectomy procedures to treat acute appendicitis, laparoscopic appendectomy is not necessarily the best treatment modality. The aim of this study is to examine the value of laparoscopic intracorporeal knotting and glove endobag in terms of various parameters and in terms of reducing the costs related to laparoscopic appendectomy procedures. Seventy-two acute appendicitis patients who underwent laparoscopic appendectomy and open appendectomy surgery were enrolled in the study and were evaluated prospectively. The patients were divided into two groups: group 1 was treated with laparoscopic appendectomy using laparoscopic intracorpreal knotting and glove endobag (n=36) and group 2 was treated with open appendectomy (n=36). The two groups were statistically compared in terms of preoperative symptoms and signs, laboratory and imaging findings, operation time and technique, pain score, gas and stool outputs, duration of hospital stay, return to normal activity, and complications. No statistically significant differences were found between the groups in relation to gender, age, body mass index, or pre-operation findings, which included loss of appetite, vomiting, time when pain started, displacement of pain, defense, rebound, imaging methods, and laboratory and pathology examinations (p>0.05). Moreover, there were no differences between the groups with respect to drain usage, hospital stay time, or complications (p>0.05). In contrast, a statistically significant difference was found between the groups in terms of operation time, pain scores, gas-stool outputs, and return to normal activity in the laparoscopic appendectomy group (p=0.001). Laparoscopic appendectomy can be performed in a facile, safe, and cost-effective manner with laparoscopic intracorporeal knotting and glove endobag. By using these techniques, the use of expensive instruments can be avoided when performing laparoscopic appendectomy.

Despite its relatively protected position, the liver is the most frequently injured solid intra-abdominal organ.1 Most liver injuries can be managed conservatively, but about 5% to 10% require urgent laparotomy, usually when the mechanism of injury involves a vehicle accident and hemodynamic instability persists, in spite of 40 mL/kg of blood transfusion.2,3 In particular, grades IV and V liver injuries may pose a challenge to the surgeon trying to control hemorrhage, the leading cause of mortality.4 Traumatic injuries to the portal vein are rare but devastating. The mortality rate for portal vein injury ranges from 50% to 70%. A recent study of portal triad injuries has highighted the higher mortality rates associated with combination injuries involving multiple portal triad components, especially those that include portal vein injury.5 This case study describes a unique case of relatively minor trauma in a child resulting in portal triad injury, sudden demise, and surgical repair.

Objective: Geriatric patients have more complicated appendicitis, which leads to higher morbidity and mortality rates. Sarcopenia has been shown to have a negative impact on patients undergoing surgery. This study aims to reveal the predictive value of computerized tomography‐assessed (CT‐assessed) sarcopenia for complicated appendicitis in geriatric patients.Methods: One‐hundred fifty‐four patients’ with acute appendicitis age, gender, co‐morbidities, appendicitis status, and body mass index (BMI) values were analyzed. The skeletal muscle index (SMI) and related measurements were evaluated.Results: Fifty‐two percent of the patients had complicated, and 48% had uncomplicated appendicitis. There was a statistically significant difference between uncomplicated and complicated cases regarding BMI, SMI, and muscle area values (P < 0.05). The cutoff point by Receiver Operating Characteristic Curve analysis was conducted for SMI and showed 71% sensitivity and 52% specificity (P = 0.042). Multivariate analysis has shown that comorbidities are significantly more associated with complicated appendicitis than sarcopenia.Conclusion: Geriatric patients with lower BMI, decreased muscle area, and CT‐detected sarcopenia have an increased risk of complicated appendicitis. Comorbidities are also important risk factors. Surgeons should be aware of factors leading to complicated appendicitis, which may cause higher morbidity and mortality rates in elderly patients.
