IRCT20180720040533N2 IRCT 2022-07-10 Tehran University of Medical Sciences Diagnosis of hidden peritoneal metastases in gastric cancers Diagnosing the prevalence of hidden peritoneal metastases of Gastric cancers by laparoscopy 2022-07-23 anticipated 90 Complete https://irct.ir/trial/64352 interventional Randomization: N/A, Blinding: Not blinded, Placebo: Not used, Assignment: Single, Purpose: Diagnostic. 2 Gastric cancer. Intervention group: At the beginning of the laparoscopy, the entire abdominal area, including the stomach, peritoneum, omentum, pelvis, and liver, is examined with a 30-degree camera, and if there is free fluid in the abdomen, the fluid will be sampled.In the absence of free fluid in the abdomen, Serous viscera in the abdomen and stomach are lavaged with 100 cc of normal saline and then the lavage fluid is aspirated and sent for cytological examination.Then all the peritoneum is examined and if there is any lesion suspected of metastasis in the mentioned areas, a biopsy lesion is performed and a sample is sent for pathological examination.. Yes - There is a plan to make this available What will be shared: The results of the study will be published as an article When: 6 months after the publication of the article To whom: Academic researcher groups Conditions: Share experiences Where to obtain: Dr. Farzad vaghef Davari How to obtain: One month after receiving the email Comments: Email address: fvdavari@sina.tums.ac.ir
