The term “kissing ulcers” of the duodenum describes the presence of two different ulcers facing each other, usually one located anteriorly and the other posteriorly. It appears that the original description was in the surgical literature by Stabile et al in 1979 (Arch Surg). The photo shows a spectrum of kissing ulcers. Occasionally, these may be hard to see (Panel C, yellow arrows).
Multiple duodenal ulcers are a “red flag” and should always intrigue the endoscopist to think of: use of NSAIDs, Zollinger-Ellison syndrome, ischemia, vasculitis, Crohn’s disease, Bechet’s disease, lymphoma, and in immunocompromised or transplant patients think cytomegalovirus, GVHD.
This citation is from the paper by Stabile et al: “Among 70 cases of perforated duodenal ulcers treated by plication, eight were complicated by massive postoperative hemorrhage from a synchronous posterior "kissing" duodenal ulcer. Critical analysis revealed that only signs of gastrointestinal (GI) bleeding preoperatively had predictive value for postoperative hemorrhage. Twenty-four patients had one or more predictive signs, and eight actually bled postoperatively. There was a 50% mortality and 75% additional complication rate for the bleeders. In contrast, the non-bleeders had a mortality and a complication rate of only 18% and 35%, respectively.” (1)

Recognizing subtle but critical findings like kissing ulcers is a crucial skill. As the 1979 Stabile paper reminds us, these ulcers present a high risk of life-threatening hemorrhage—a situation every endoscopist must be prepared to manage.
