One patient with positive margins after cecal resection underwent subsequent right hemicolectomy and was free of disease after 4 years of follow-up; one patient with CD and LAMN was lost to follow-up and developed pseudomyxoma peritonei 10 years later; one post-operative death was reported (an acute onset of CD complicated by signet ring adenocarcinoma of the appendix) and one patient developed a UC relapse soon, with a later right hemicolectomy requiring anti-TNF drugs. Here, TNF is linked to pseudomyxoma peritonei.
