Serosa invaded tumour is considered as the worst outcome in the patients with GC. PM is generally seen in about 25-50% of total number of GC patients. Few previous studies have shown that computed-tomogrpahy (CT) scan due to its limited accuracy in differentiating each layer of the gastric wall. However it is known that the sensitivity of CT is limited to 13-30% of peritoneal metastasis (PM). Thus PM’s are mostly detected intraoperatively due to these CT limitations. It was proven from previous studies that PM is often reflected by the presence of intraabdominal fat’s soft-tissue stranding, omental cake, abnormal contrast enhancing resulting in peritoneal thickening and nodules on peritoneal surface. To make a decision between taking up a therapeutic approach like curative resection or palliative surgery, detection of PM is a crucial thing as patients with PM are known to be critical cases to cure and are mostly incurable. Mean age of study population was statistically calculated to be 59.7 ± 13.8, total number of male patients included in the study were of 67 accounting to a percentage of 57.26%, number of patients diagnosed with peritoneal metastases were of 15 with a percentage of 12.82%, tumour marker elevation was observed in 16 patients with a percentage of 13.67%, amount of ascites in terms of mL was observed to be in 12.57 ± 30.11 in an average. A total of 15 patients have been diagnosed with peritoneal metastases and the rest of the patients did not have peritoneal metastases. Patients with PM included 8 male patients with a percentage of 53.33%, and 4/9 tumour marker elevation was recorded, amount of ascites were of 47.52 52 ± 60.21 in patients with PM whereas, it was 9.45 ± 12.54 in non-PM patients. Endoscopic findings reveal that the patients with PM are with advanced gastric cancer and no patient with early gastric cancer had PM. On detection of volumes of ascites present in both the groups it was clear that the high volume of ascites was reported in association with patients with peritoneal metastases. However, ascites are considered as independent factors for PM
