A structured protocol exists for patients with dumping syndrome whose symptoms remain inadequately controlled after somatostatin analogue therapy — defining both the conditions that indicate escalation and the interventions to consider next.

Previous line — failure condition

Somatostatin analogues (octreotide, pasireotide, lanreotide) were used as the prior treatment line. Escalation to this protocol is triggered when they fail to achieve at least a 50% reduction in dumping symptoms, or when clinical efficacy cannot be maintained in long-term use.

Next-step approach — partial overview

For refractory dumping syndrome at this stage, the protocol addresses last-resort options spanning both interventional and off-label pharmacological approaches. The complete eligibility criteria, specific options, and sequencing are available in the full protocol.

After conservative steps have failed to manage symptoms of dumping syndrome, continuous enteral feeding or surgical interventions can be considered.

Continuous enteral feeding by a jejunostomy or tube in the remnant stomach avoids symptoms triggered by meals but is invasive, associated with complications and has therefore a limited place in the management of dumping syndrome.

In the literature, this procedure is referred to as transoral outlet reduction (TORe), or endoscopic gastrojejunostomy revision (EGJR), or revision of the gastrojejunal anastomosis (GJA).

Successful use of GLP-1RAs has also been described in individual cases: a patient with postsurgical late dumping syndrome symptoms after Toupet fundoplication (liraglutide) and a patient after distal gastrectomy (beinaglutide) by reducing symptomatic postprandial hyperinsulinemic hypoglycemic events.

Indeed, in a small-scale study with 21 patients, the SGLT-1 inhibitor canagliflozin reduced over 85% of the hypoglycemic episodes in patients with severe postprandial hypoglycemia.
