- Preserves duodenal and jejunal continuity
- Anastomosing the remnant stomach to the duodenal stump in a primary end-to-end fashion.
- Billroth I reconstruction is the preferred method of reconstruction when the proximal gastric remnant and the duodenal stump can be approximated without tension, which is generally possible only after antrectomy.
Post-Gastrectomy Syndromes
- The most common postgastrectomy syndrome associated with Billroth I reconstruction is reflux of biliary contents retrograde into the stomach, causing alkaline gastritis.
- If the residual gastric remnant is small or nonfunctional, there will likely be some degree of dumping.
