    Abstract
    Indroduction:
    Machine learning is a branch of artificial intelligence based on the idea that systems can learn from data, identify patterns, and make decisions with minimal human intervention.

    Aim:
    Our aim is to predict acute appendicitis, which is the most common indication for emergency surgery, using machine learning algorithms with an easy and inexpensive method.

    Materials and methods:
    Patients who were treated surgically with a prediagnosis of acute appendicitis in a single center between 2011 and 2021 were analyzed. Patients with right lower quadrant pain were selected. A total of 189 positive and 156 negative appendectomies were found. Gender and hemogram were used as features. Machine learning algorithms and data analysis were made in Python (3.7) programming language.

    Results:
    Negative appendectomies were found in 62% (n = 97) of the women and in 38% (n = 59) of the men. Positive appendectomies were present in 38% (n = 72) of the women and 62% (n = 117) of the men. The accuracy in the test data was 82.7% in logistic regression, 68.9% in support vector machines, 78.1% in k-nearest neighbors, and 83.9% in neural networks. The accuracy in the voting classifier created with logistic regression, k-nearest neighbor, support vector machines, and artificial neural networks was 86.2%. In the voting classifier, the sensitivity was 83.7% and the specificity was 88.6%.

    Conclusions:
    The results of our study show that machine learning is an effective method for diagnosing acute appendicitis. This study presents a practical, easy, fast, and inexpensive method to predict the diagnosis of acute appendicitis.

    Abstract Background: It is controversial which treatment method is superior in plastron appendicitis and the research is still going on. The aim of this study is to compare treatment methods for plastron appendicitis in the adult population with our experience.
    Materials and methods: The data of 92 patients who were diagnosed with plastron appendicitis in university hospital between 2015 and 2021 were analyzed retrospectively. Data were taken from the hospital database. The patients were divided into three groups: those treated with primary surgery, with interval appendectomy and only with conservative method.
    Results: Interval appendectomy resulted in a lower rate of conversion to open surgery compared to primary surgery, shorter operative time, and lower complication rates. Surgical procedures were found to be superior in detecting neoplasms compared to conservative treatment. After conservative treatment, one of three patients was retreated with the diagnosis of acute appendicitis.
    Conclusion: In plastron appendicitis, routine interval appendectomy can be performed due to its advantages over other treatments such as the frequency of attacks after conservative treatment, the risk of the tumor being overlooked in conservative treatment, and the high rate of complications and conversion to open surgery in the primary surgery group.

    Abstract Background: The purpose of this study was to evaluate the effects of intravenous zoledronic acid applied systemically on osseointegration of dental implants and the surrounding bone mineral density (BMD) in the ovariectomized rats.
    Material and methods: 36 rats were divided into three groups: control (CTRL), ovariectomy (OVX), and ovariectomy-zoledronic acid (OVX/ZOL). The rats in the CTRL group underwent sham surgery, while rats in OVX and OVX / ZOL group underwent ovariectomy. After 12 weeks, rats from OVX / ZOL were injected with 0.04 mg/kg ZOL intravenously once a week for 6 weeks. The rats from CTRL and OVX groups were injected with 0.9% NaCl. Implants were placed in the left tibia. After 8 weeks, rats were sacrificed and tibia bones were removed for radiodensitometric examination. Digital radiographs of bones' lateral surface were taken. The BMD was measured by using radiographic analysis software.
    Results: Statistically significant differences were found between all groups (p<0.05). While highest mean BMD values were observed in the CTRL group, the lowest were in the OVX group.
    Conclusions: The systemic use of ZOL has increased the bone density around the implants inserted osteoporotic rat tibia.

    Abstract Gastritis cystica profunda (GCP) is a rare condition characterized by polypoid cystic ectasia of the submucosal layer with cystic dilatation of the glandular structures of the stomach. The probable pathogenesis refers to degradation of the integrity of the muscularis mucosa and migration of epithelial cells to the submucosal layer. The most common cause known in the literature for this occurrence is previous stomach surgery. A case presented with two GCP lesions in different locations in the stomach without any history of previous surgery.

    Abstract Background: Although primer appendagitis epiploica (PAE) is an acute condition, there is no consensus about a standard first-choice treatment. Different non-surgical and surgical interventions for PAE are available.
    Methods: In this study, a total of 39 patients who were diagnosed as PAE between 2013-2018 were evaluated retrospectively concerning recurrences of the disease, medical intervention, and the requirement of hospitalization. USG and abdominal CT were used as diagnostic tools. Patients were also evaluated for a one-month and long-term follow-up.
    Results: Of the 39 patients, 29 were male and 10 were female. Recurrence was seen in three patients at the earliest six months. These patients responded to medical treatment.
    Conclusion: Accurate diagnosis with the help of developing imaging methods has made non-surgical treatment a viable option in the treatment of PAE.

    Abstract Objectives: Although non-traumatic Small Bowel Perforations (SBPs) are rare, they have high rates of morbidity and mortality in case of late presentation. Aetiological factors vary across different geographical regions. In this paper, SBPs caused by anything other than trauma and other well-known causes are presented and the current literature is reviewed.
    Methods: The study was conducted at General Surgery Clinics of two different tertiary university hospitals between January 2008 and September 2016. The authors directly involved in managing the patients. This study was approved by the ethical institutional board and was performed at the Department of General Surgery, School of Medicine, Sakarya University. The medical records of patients retained in both hospitals are electronic. Medical records of subjects who had undergone emergency operations with a prediagnosis of acute abdomen in single center, and were determined to have SBPs due to unusual causes, were investigated retrospectively. Patients with aetiological factors such as trauma, mesenteric vascular disease, internal and external hernias, intra abdominal adhesions, inflammatory bowel diseases, and iatrogenic causes were excluded.
    Results: In total, 35 patients were evaluated, 20 (57.1%) males and 15 (42.9%) females. The mean age of the cases was 51.6 (18-88) years. Mean time until admission at the hospital was 1.4 days (range 0.25-7 days). The most frequent aetiological factors were various malignancies (10 cases, 28.5%) and perforation of Meckel's diverticulum (8 cases, 22.8%). It was surprising to detect a considerable rate of perforation due to bezoars (6 patients, 17.1%).
    Conclusions: Post-operative consequences of SBPs due to unusual causes are similar with those related to common, known causes. Factors affecting the clinical course are presentation time and patients' clinical status in admission, not aetiology.

    Abstract Background: Although laparoscopic appendectomy increases its popularity today, the answer to the question of whether to perform open or laparoscopic appendectomy during pregnancy is appropriate in many studies, and the choice of surgery depends on the surgeon. Herein, we aimed to evaluate the variables that affect undesirable pregnancy outcomes that occur as a result of appendicitis during pregnancy.
    Methods: Seventy-eight pregnant patients with acute appendicitis who underwent laparoscopic or open technique intervention enrolled in this retrospective study. In addition to the demographic structure of the patients, surgical technique, the number of pregnancies, multiple pregnancy status, surgical pathologies, laboratory values, radiological imaging methods, and length of hospital stay were evaluated. The severity of appendicitis was classified according to the pathology results. The patients were divided into two groups according to the outcomes of their pregnancy. Preterm delivery and abortion involved in the study as a single complication section.
    Results: The mean age of the pregnant patients was 28.6 ± 5. Of the 78 pregnant women with appendicitis, 47.4% had their first pregnancy, 37.2% had their second pregnancy, and 15.4% had 3 or more pregnancies. The preterm delivery and abortus were 19.5% in the open appendectomy (OA) group and 16.2% in the laparoscopic appendectomy (LA) group. No statistically significant difference was detected in this group in terms of appendicitis pathology triggering preterm delivery or abortion (
    Conclusion: Consequently, acute appendicitis may cause serious intra-abdominal infection and inflammation in addition to the complexity of the diagnosis due to the nature of pregnancy, as well as undesired pregnancy outcomes with the surgical technique, or independently with other variables.

    Abstract Behçet's disease is a systemic inflammatory disease that may affect multiple organs. However, intraabdominal complications requiring surgical intervention are rare in the natural course of the disease. A 32-year-old male patient with Behçet's disease who had been followed for 5 years with a diagnosis of acute abdominal syndrome was operated on twice in 18 days. Intestinal ischemia was identified in different segments of the jejenum during each operation. Recurrent segmental intestinal ischemia within a short time interval is rare, although the gastrointestinal involvement can be seen in the normal course of Behçet's disease.
