Risk factors for delayed gastric emptying caused by anastomosis edema after subtotal gastrectomy for gastric cancer.Hepatogastroenterology. 2014 Sep; 61(134):1794-800.H
Delayed gastric emptying (DGE) is one of the most troublesome complications after subtotal gastrectomy for gastric cancer. We evaluated operative and perioperative variables to assess for independent risk factors of DGE caused by anastomosis edema.
The study retrospectively reviewed clinical data of 382 consecutive patients who underwent subtotal gastrectomy for gastric cancer between 2009 and 2011 at a single institution.
Delayed gastric emptying had occurred in twelve patients (3.1%). Univariate analysis revealed high body mass index (>25kg/m2), open gastrectomy, and Billroth II or Roux-en Y reconstructions to be significant factors for delayed gastric emptying. Multivariate analysis identified high body mass index and open gastrectomy as predictors of delayed gastric emptying.
To avoid delayed gastric emptying, surgeons should take care in creating the gastrointestinal anastomosis, particularly in patients with high BMI or in cases of open gastrectomy.
