“Duodenal stump leakage (DSL) is a postoperative complication specific to patients with the formation of a blind endof the duodenum, e.g., Roux-en-Y or Billroth-II reconstruction. The incidence of DSL after radical gastrectomy with a duodenal stump ranges between 1.8% and 7.7%, with a mortality rate of 7–67%.”
“Although manual reinforcement of the duodenal stump is equally effective in preventing DSL development in both laparoscopic and open surgeries, it may not be routinely performed because of its technical difficulty during laparoscopic gastrectomies.”

“The present study revealed that the incidence of DSLs after gastrectomies with duodenal stumps was 0.93%, which was lower than that found in previous estimations. However, the
mortality rate was 7.8% (12/153) when DSL developed. Duodenal stump reinforcement should be performed to prevent DSL, a complication associated with a high mortality
rate if its development is not prevented. While SMS stands as the preferable method of reinforcement, the use of a RS may also be acceptable. For patients who are at a high risk
of mortality after the onset of DSLs (i.e., those with poor general conditions or duodenal invasions), it is important to be more careful to prevent subsequent serious events.”
