Successful use of neostigmine for resistant gastroparesis following distal gastrectomy: A case report
Abstract
INTRODUCTION AND IMPORTANCE: Although short acting acetyl cholinesterase inhibitors are used in colonic or small bowel pseudo-obstruction, their use in post-surgical gastroparesis is not clear. We demonstrate the successful use of neostigmine in a patient with resistant gastroparesis following distal gastrectomy.
CASE PRESENTATION: A 73-year-old male presented with features of gastric outflow obstruction 3 weeks following a distal gastrectomy. Prior to 3 weeks, he underwent an uneventful open distal gastrectomy for an incidentally detected low grade gastrointestinal stromal tumour (GIST) of the gastric antrum. An omega-loop isoperistaltic, 2-layer, posterior, retrocolic gastrojenunostomy was performed with a jejuno-jejunostomy. Abdominal ultrasonography was negative for intra-abdominal collections. Gastrograffin study and endoscopy ruled out an obstruction. A trial of prokinetics was unsuccessful with persistent nasogastric tube drain. Intravenous neostigmine was commenced with immediate symptomatic relief, reduction of abdominal distension and bowel evacuation without any cardiac adverse effects. At 6 months follow up, the patient was tolerating normal diet with no recurrence of symptoms.
CLINICAL DISCUSSION: The management of post-surgical gastroparesis is challenging. Although various prokinetics are described for gastric motility disorders, the studies among post-gastrectomy patients with gastroparesis are limited. In our patient, the successful administration of…
