[Two Suggestive Cases of Tumor Resection for Bowel Obstruction Due to Malignant Lymphoma of the Ileum].

Two notable cases of bowel obstruction caused by diffuse large B-cell lymphoma(DLBCL)of the ileum were encountered. The first case, a 73-year-old man, presented with intussusception into the ascending colon, originating from an ileal tumor. He underwent ileocecal resection with lymph node dissection and later received R-CHOP chemotherapy, remaining recurrence- free for 1 year. The second case, a 75-year-old woman, had a large tumor infiltrating the abdominal wall in the right pelvis. She underwent right colectomy combined with abdominal wall and lymph node resection. However, rapid tumor progression post-surgery left no opportunity for chemotherapy, and she passed away 67 days later. These cases underscore the critical need to carefully evaluate the extent of surgical intervention for patients who may benefit from chemotherapy.
