Roux-en-Y gastric bypass (RYGB) is a highly effective surgical approach for the treatment of morbid obesity [1]. Postsurgical bleeding leading to intraluminal blood clot formation causes gastric outlet obstruction (GOO) at the site of the anastomosis, and is typically managed by laparotomy or surgical revision [1] [2]. Gastrojejunal clots causing GOO following laparoscopic RYGB occur in 3 % – 27 % of patients [2]. Endoscopic dilation of gastrojejunal obstruction provides an alternative to surgical revision, but symptomatic relief may require up to three dilations [3] [4]. We present a case series of three patients who developed intraluminal blood clots at the gastrojejunal anastomosis (GJA) within 72 hours of robotically assisted RYGB surgery.
The first case was a 63-year-old woman with morbid obesity (body mass index [BMI] 42 kg/m2) who presented with persistent nausea and vomiting for 3 days after an elective RYGB. Routine upper gastrointestinal series revealed no evidence of emptying into the alimentary limb. Subsequent esophagogastroduodenoscopy revealed a large blood clot at the GJA ([Fig. 1]). After unsuccessful attempts to irrigate the clot, biopsy forceps were utilized to fragment it. In addition, an 8-mm balloon was advanced twice through the clot and inflated to successfully create a lumen ([Fig. 2]).

The second and third cases were a 53-year-old woman (BMI 46 kg/m2) and a 29-year-old woman (BMI 43 kg/m2), respectively, who presented with nausea for 3 days after RYGB surgery. Upper gastrointestinal series revealed retention of contrast in the gastric pouch, suggesting stricture at the GJA. In both patients, a 10-mm gastroscope was used to break up the clot, and create a lumen through which passage into the alimentary limb was possible ([Fig. 3] and [Fig. 4]).

All three patients experienced relief of GOO without undergoing surgical revision, resulting in a shorter hospital stay and lower morbidity [4] [5]. Moreover, these cases show that a single dilation may be sufficient to provide relief.
