There was a firm 6-cm nodule in the pericolic
fat that also had a tan-white firm cut surface.
The pathology report was as follows: adenocarcinoma, Astler-Coller stage C2, and there was only one pericolic
lymph node metastasis.
CT of prominent pericolic
or perienteric vasculature in patients with Crohn's disease: Correlation with clinical disease activity and findings on barium studies.
His chest x-ray was normal, but computed tomography (CT) scan of the abdomen revealed a large polypoid mass lesion in the right colon extending from the ileo-caecal valve with lumen-narrowing and mildly enlarged pericolic
Approximately 15% of patients with acute diverticulitis will develop an associated pericolic
or intramesenteric abscess.
1 * T1 = tumour invades submucosa; T2 = tumour invades muscularis propria; T3 = tumour invades through the muscularis propria into the subserosa nonperitonealised pericolic
tissues; T4 = tumour directly invades other organs or structures and/or perforates visceral peritoneum; N0 = no regional lymph note netastasis; N1 = metastasis to one to three regional lymph nodes; N2 = metastasis to four or more regional lymph nodes; M0 = no distant metastasis; M1 = distant metastasis.
Histological examination showed the tumour had breached the serosa into the pericolic
Krystyna Kiel said the guidelines now recommend FOLFOX as an option for adjuvant therapy for a variety of patients: those with primary tumors invading through the muscularis propria into the subserosa or into the non-peritoneal pericolic
or perirectal tissues; those with any level of primary tumor and metastases to one or more regional lymph nodes; and those with any level of primary tumor, any number of regional lymph node metastases, and distant metastasis.
We report here a conservative treatment after microcoil embolisation with antibiotics and percutaneous drainage of pericolic
Tumor invades through the muscularis propria into the subserosal adipose tissue or the nonper itonealized pericolic
or perirectal soft tissues but does not extend to the serosal surface (visceral peritoneum)

More advanced lesions, including any involving lymph node metastases, and any without lymph node metastases that invade the muscularis propria, the subserosa, or non-peritonealized pericolic
or perirectal tissues, or those that directly invade other organs or structures require mitomycin/5-EU therapy plus radiotherapy at 55-59 Gy the guide-lines state.
