Endoscopic partial reversal of complicated single anastomosis gastric bypass
Prior to the widespread use of therapeutic endoscopy, surgery was the only way to achieve restoration of normal bowel continuity after resection and bypass of a diseased or obstructed gastrointestinal tract. However, with the advancement of endoscopic skills and devices, endoscopic approaches now provide possible alternatives [1] [2] [3] [4] [5]. This procedure is particularly useful for patients with hostile abdomen and high operative risk.
A 68-year-old man underwent a laparoscopic single anastomosis or mini-gastric bypass (MGB), with 1.5 metre bilio-pancreatic limb, in 2013 for morbid obesity and poorly controlled diabetes mellitus. Postoperatively, he suffered from severe malnutrition despite increasing oral intake and protein supplements. He was experiencing diarrhea and bilateral lower-limb edema secondary to hypoalbuminemia (18 g/L). He underwent a computed tomography-guided insertion of a gastrostomy tube into the excluded stomach in January 2018 to optimize nutrition by recruiting the excluded foregut. An elective endoscopic partial reversal of MGB ([Fig. 1], [Video 1]) was then performed 5 months later.

The procedure was performed under general anesthesia. Fluoroscopy was utilized throughout for adjunct imaging. Two operators, each with individual endoscopy towers, were required for the procedure ([Fig. 2]). The first operator inserted a 5-mm gastroscope (GIF-XP160; Olympus, Tokyo, Japan) with a 24-Fr peel-away sheath (MIC-KEY; Halyard, Alpharetta, Georgia, USA) through the gastrostomy tract into the excluded stomach, while an echoendoscope (GF-UC140P-AL5; Olympus) was introduced transorally into the gastric pouch by the second operator. The ideal location for the gastro-gastric anastomosis was selected by using fluoroscopy ([Fig. 3 a]) and endoscopic visualization. A 19-gauge Flex endoscopic needle (Boston Scientific, Marlborough, Massachusetts, USA) was inserted through the echoendoscope to access the remnant stomach and a 0.025-inch VisiGlide guidewire (Olympus) was placed. A 15 × 10 mm Hot Axios stent (Boston Scientific) was deployed ([Fig. 3 b]) and dilated to 10 mm using a balloon (CRE Balloon-Dilator; Boston Scientific). A pediatric gastroscope was used to confirm satisfactory stent placement ([Fig. 3 c]). This procedure took approximately 60 minutes.
At follow-up 2 months later, the patient’s weight had increased from 61.8 kg to 65.8 kg and albumin levels had increased to 32 g/L. Contrast study after 3 months showed smooth flow of contrast through both the stent and the anastomosis, at a ratio of 60:40 ([Fig. 3 d]).
