Nuclear Scintigraphy gastric clearance and intestinal delivery. a–d are schematic representations of proportional emptying of a patient at 6 weeks (a and b) and 12 months (c and d) post sleeve gastrectomy. a illustrates a uniform retained stomach with hyper-acceleration of emptying into the small bowel at T = 2 min (6 week scan). b illustrates most (97.2%) of the meal in the small bowel at T = 90 min (6 week scan). c illustrates proximal retention and little emptying into the small bowel at T = 2 min (12 month scan). d illustrates an increase in meal retention in the stomach and lesser (91.1%) emptying into the small bowel T = 90 min (12 month scan)
