Background and Methods After endoscopic treatment to controlbleeding of peptic ulcers, bleeding recurs in 15 to 20 percentof patients. In a prospective, randomized study, we comparedendoscopic retreatment with surgery after initial endoscopy.Over a 40-month period, 1169 of 3473 adults who were admittedto our hospital with bleeding peptic ulcers underwent endoscopyto reestablish hemostasis. Of 100 patients with recurrent bleeding,7 patients with cancer and 1 patient with cardiac arrest wereexcluded from the study; 48 patients were randomly assignedto undergo immediate endoscopic retreatment and 44 were assignedto undergo surgery. The type of operation used was left to thesurgeon. Bleeding was considered to have recurred in the eventof any one of the following: vomiting of fresh blood, hypotensionand melena, or a requirement for more than four units of bloodin the 72-hour period after endoscopic treatment.
Results Of the 48 patients who were assigned to endoscopic retreatment,35 had long-term control of bleeding. Thirteen underwent salvagesurgery, 11 because retreatment failed and 2 because of perforationsresulting from thermocoagulation. Five patients in the endoscopygroup died within 30 days, as compared with eight patients inthe surgery group (P=0.37). Seven patients in the endoscopygroup (including 6 who underwent salvage surgery) had complications,as compared with 16 in the surgery group (P=0.03). The durationof hospitalization, the need for hospitalization in the intensivecare unit and the resultant duration of that stay, and the numberof blood transfusions were similar in the two groups. In multivariateanalysis, hypotension at randomization (P=0.01) and an ulcersize of at least 2 cm (P=0.03) were independent factors predictiveof the failure of endoscopic retreatment.
Conclusions In patients with peptic ulcers and recurrent bleedingafter initial endoscopic control of bleeding, endoscopic retreatmentreduces the need for surgery without increasing the risk ofdeath and is associated with fewer complications than surgery.
