The geographical location and differences in tumor biology significantly change the management of gastric cancer. The prevalence of gastric cancer ranks fifth and sixth among men and women, respectively, in Turkey. The international guidelines from the Eastern and Western countries fail to manage a considerable amount of inconclusive issues in the management of gastric cancer. The uncertainties lead to significant heterogeneities in clinical practice, lack of homogeneous data collection, and subsequently, diverse outcomes. The physicians who are professionally involved in the management of gastric cancer at two institutions in Istanbul, Turkey, organized a consensus meeting to address current problems and plan feasible, logical, measurable, and collective solutions in their clinical practice for this challenging disease. The evidence-based data and current guidelines were reviewed. The gray zones in the management of gastric cancer were determined in the first session of this consensus meeting. The second session was constructed to discuss, vote, and ratify the ultimate decisions. The identification of the T stage, the esophagogastric area, imaging algorithm for proper staging and follow-up, timing and patient selection for neoadjuvant treatment, and management of advanced and metastatic disease have been accepted as the major issues in the management of gastric cancer. The recommendations are presented with the percentage of supporting votes in the results section with related data.
Portal vein ligation and in situ liver splitting in metastatic liver cancer

The most serious complication after major liver resection is liver failure. Depending on preoperative liver function, a future liver remnant of 25\%-40\% is considered sufficient to avoid postoperative liver failure. A new technique known as portal vein ligation combined with in situ splitting has been developed to obtain rapid liver hypertrophy. Herein, we present a case where we performed portal vein ligation combined with in situ splitting, A 37-year-old male patient with a diagnosis of sigmoid adenocarcinoma and liver metastasis underwent anterior resection because of an obstructing sigmoid tumor and received palliative chemotherapy. After chemotherapy, abdominal computed tomography revealed a lesion, 50 mm in diameter, localized between segments 5-8 of the liver on the bifurcation of the anteroposterior segmental branch of the right portal vein. Computed tomography volumetric assessments of the liver were performed in the preoperative period, and it was found that the remnant left liver volume was less than 25\% In the first stage, portal vein ligation and in situ splitting of the liver parenchyma were performed, On the second and sixth postoperative clays, computed tomography revealed hypertrophy of the left liver lobe. On the sixth clay, a right hepatectomy was performed, Portal vein ligation combined with in situ splitting has been used by surgeons worldwide to obtain rapid and adequate liver hypertrophy. This new approach yields hope for patients with locally advanced liver tumors and may increase the number of curative resections for primary or metastatic liver tumors.
Predictive parameters of early postoperative complications in Crohn's disease: Single team experience

Background/Aims: Most of the patients with Crohn's disease (CD) may require at least one surgical procedure over their lifetime. However, these patients tend to have a high incidence of postoperative complications. The aim of this retrospective study was to investigate the predictive parameters of postoperative complications in CD. Materials and Methods: All consecutive patients with CD between March 2001 and March 2016 who underwent bowel resection were included to this study. Postoperative complications were divided as
