Abstract

OBJECTIVES: To evaluate the role of sleeve gastrectomy (SG) in gastrointestinal motility. BACKGROUND: SG is a widely used bariatric operation leading to weight loss and early improvement of patient's metabolic profile. Current data indicate faster postoperative gastric emptying, but detailed studies on alterations in small bowel motility are missing. DESIGN: We evaluated 21 morbidly obese patients who underwent laparoscopic SG before and 4 months after the procedure. After consumption of a semisolid radiolabeled meal, their gastric and intestinal transit times were studied with a gamma camera. Particularly the times of 10% gastric emptying, 50% gastric emptying, maximal intestinal filling, 10% terminal ileum filling, duodenal to terminal ileum transit, cecal filling initiation, and ileocecal valve transit (T ICVt) were studied pre- and postoperatively. RESULTS: Ten percent gastric emptying and 50% gastric emptying were decreased postoperatively as well as maximal intestinal filling, indicating faster gastric emptying and intestinal filling. Duodenal to terminal ileum transit and 10% terminal ileum filling also decreased as small bowel transit time accelerated and the meal reached the terminal ileum more rapidly. Contrary opening of the ileocecal valve and food transit through it were delayed, with postoperative increase in cecal filling initiation and T ICVt, respectively. CONCLUSIONS: SG accelerates gastric emptying and small bowel transit of semisolids. In addition, it delays the initiation of cecal filling and T ICVt. This early and prolonged contact of food with the distal small bowel mucosa may explain the metabolic effects of SG occurring before substantial weight loss.

  • Sleeve gastrectomy aids expedition of nutrients out of the stomach and through the proximal small bowel to quickly reach the ileum.

    “Nuclear imaging studies tracking the transit of a mixed meal have shown that sleeve gastrectomy aids expedition of nutrients out of the stomach and through the proximal small bowel to quickly reach the ileum [133].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
