Immune checkpoint inhibitors (ICIs) have become an important part of malignant tumor therapy. However, some adverse reactions follow ICIs therapy. The incidence of immune-mediated colitis (IMC) has also increased. Here, the case of a 67-year-old male patient with stage IVB esophagogastric junction squamous cell carcinoma after chemotherapy, targeted therapy and immunotherapy is presented. This patient underwent treatment with six courses of protein-bound paclitaxel + cis-platinum+ sintilimab, followed by maintenance therapy with sintilimab alone. The patient developed intestinal obstruction, abdominal pain, hemorrhage of the lower digestive tract and other discomfort and was diagnosed with multiple jejunal ulcers via colonoscopy and pathological biopsy. The aims of presenting this case report are to improve clinicians' understanding of and ability to treat sintilimab-related adverse reactions and to more scientifically and rationally administer sintilimab for the treatment of malignant tumors.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
