Objective: Gastric cancer is the second most common cancer in the world, accounting for 650,000 deaths per year, and is observed in approximately 10% of the patients diagnosed. Extracellular matrix abnormalities have been documented in gastric cancer patients. The aim of our study was to understand the role of high levels of hyaluronan, an extracellular matrix glycosaminoglycan, and its mechanistic role in gastric cancer pathobiology.

Material And Methods: A total of 213 patients who were operated with the diagnosis of AMI were enrolled in this study. Based on their operational, clinical, and pathological findings, they were divided into two groups.
Aim: In this study, we aimed to evaluate patients who underwent curative surgical treatment for primary duodenal adenocarcinoma and to present our experience.
Material And Methods: Patients diagnosed with primary duodenal adenocarcinoma between 2006 and 2018 participated in the study. The demographic and clinical characteristics of the patients, details of the operation, pathological features of the tumors, short- and long-term follow-up results, and mean survival were evaluated retrospectively.
Aim: We aim to evaluate the prognostic significance of tumor volume in esophageal cancer.
Methods: Patients who underwent curative resection due to esophageal cancer between the years 2015 and 2019 were included in the study. The Tumor Depth Parameter (TDP) was defined as mucosa and submucosa =1, muscularis propria =2, adventitia =3, and invasion into adjacent organs=4.
The discovery of ectopic adrenal tissue in the hernial sac is very rare, and in the majority of reported cases it is in children, while it is never described in adult subjects. This could be due to a progressive previous atrophy of the ectopic tissue or to an insufficient examination of the sac removed surgically. The most frequent site of these ectopias is the kidney, adjacent to the adrenal glands.

Material And Method: Patients who underwent curative resection for esophageal cancer between 2015-2019 were included in the study. Two groups, Group1 (low NLR) and Group2 (high NLR), were created.
Backround: The association of rectal prolapse and colorectal cancer is quite rare and only a few cases have been reported previously in the literature. It is unclear whether colorectal cancer triggers rectal prolapse.
Case Presentation: A 77-year-old male patient presented to our emergency department with complete rectal prolapse, and an anterior resection was performed after rectal digital examination revealed a mass.
Background: Acute mesenteric ischemia (AMI) is a potentially life-threatening condition because of its diagnostic difficulty, operative challenges, and comorbidities a patient may have. The aim of this study was to identify factors associated with adverse outcomes in patients with AMI.
Methods: The hospital records and clinical data of all patients with AMI were reviewed for a recent 4-year period.
Short bowel syndrome occurs as a result of insufficiency in the total length of the small intestine to provide adequate supply of nutrients. Seventy-five percent of cases are due to massive intestinal resection. A 35-year-old male complaining of abdominal pain was admitted to the gastroenterology department.

Background: Piperine is a spice principle, and its protective role against oxidative damage and lipid peroxidation has been reported. In this study, we aimed to investigate the effects of piperine in the prevention of ischemia-reperfusion injury to the small intestine.
Methods: Rats were allocated to three groups of 8 rats each.
Background: We have been utilizing both resection and laparoscopic radiofrequency ablation (RFA) to treat hepatocellular carcinoma (HCC). The aim of this study is to describe patient characteristics and outcome for each treatment modality from a single institution.
Methods: Medical records of HCC patients who underwent resection (n = 92) or laparoscopic (RFA) (n = 92) between 1997 and 2010 were reviewed.
Background: Neuroendocrine liver metastases have a distinct tumor biology and symptomatology that render their management challenging. This difficulty is reflected in the literature, which lacks consensus on a treatment algorithm. The aim of this study is to propose a treatment algorithm based on patient morbidity and the efficacy of different treatment options.
View Article and Find Full Text PDFBackground: Since our first report 13 years ago, laparoscopic radiofrequency ablation has been incorporated into the treatment algorithm of patients with neuroendocrine liver metastases. The aim of this study is to report long-term oncologic results.
Methods: Eighty-nine patients with neuroendocrine hepatic metastases underwent 119 laparoscopic radiofrequency ablation sessions within 13 years.
Background: There are scant data in the literature regarding the role of robotic liver surgery. The aim of the present study was to develop techniques for robotic liver tumour resection and to draw a comparison with laparoscopic resection.
Methods: Over a 1-year period, nine patients underwent robotic resection of peripherally located malignant lesions measuring <5 cm.
Background: Although radiofrequency-assisted (RF) precoagulation has been described for open resections, there is little data evaluating precoagulation options in laparoscopic liver resection. The purpose of this study is to provide an algorithm for the use of monopolar and bipolar RF devices in laparoscopic liver resection.
Methods: Patients undergoing laparoscopic liver resection utilizing precoagulation during the period 2007-2009 were identified from a prospectively maintained, institutional review board-approved database.
Objective: To define the value of multislice computed tomography (CT) in the diagnosis of acute mesenteric ischemia (AMI).
Materials And Methods: Two hundred patients (age range: 20-92 years) who were referred to the emergency CT department with a clinical suspicion of AMI were prospectively included in the study. CT examinations were performed with a multislice (16) CT scanner and the protocol included pre-contrast, arterial and venous phase acquisitions.

Background: A patient with acute abdominal pain requires rapid evaluation. In these patients, it is very important to distinguish between surgical and nonsurgical pathology. Our aim was to compare the accuracy of the leukocyte count and D-dimer test in the diagnosis of acute abdomen.

Background: Intestinal perforation is one of the major causes of obligatory surgical intervention. There can be many different causes of perforation. The aim of this study was to evaluate the unusual causes and the surgical treatment.
