Aims Ampullary lesions (AL) are a rare condition but may be clinically significant by obstruction, jaundice, bleeding or malignant transformation. Main resection techniques comprise the endoscopic papillectomy (EP), the surgical ampullectomy (SA) and pancreaticoduodenectomy (PD). Since consistent comparative data are lacking, we performed a retrospective multicenter center study (Endoscopic-Papillectomy-versus-Surgical-Ampullectomy-versus-Pancreaticoduodectomy (ESAP)) comparing the most frequent procedures, i.e. EP and PD.

Methods On 1330 EP and 1095 PD included in the database, we performed a propensity score matching (nearest-neighbor-method) with regard to age, gender, size and histology of the lesion (adenoma, T1- and T2-adenocarcinoma), ASA-score and previous treatment. Main outcomes were proportions of complete resection (R0), complications, recurrence and hospital stay. Dispersions between EP and PD group were calculated by means of chi-square-test, Students’ t-test and Mann-Whitney-U-test.

Results Propensity-score-matching identified 270 pairs of patients. Baseline characteristics age (EP: 66.9y, PD: 70.4y, p = 0.315), ASA-score (≥3 EP: 85, PD: 87, p = 0.926), histology (non-neoplastic: 29 vs. 27, Adenoma 115 vs. 118, invasive Cancer 114 vs. 134, other: 22 vs. 11, p = 0.114) and previous treatment (EP: 6.3 %, PD: 9.3 %, p = 0.261) were comparable. However, we were not able to perfectly match lesion size (EP: 20.8mm, PD: 26.6 mm, p = 0.009) and gender (male gender: 48.5 % vs. 58.1 %, p = 0.025). Initial R0-rate was only 50 % for EP and 99.3 % for PD (p<0.001). However, in all EP-patients who underwent an EP-retreatment (30 % of R1 patients), a final R0 was achieved. Complications were significantly higher in PD (≥ moderate: 18.9 % vs. 58.9 %, 0 vs. 9 deaths, p < 0.001) and PD-group revealed a significant longer hospital stay (7.0 vs. 24.5 d, p < 0.001). EP-group showed a higher rate of recurrences (29.6 % vs. 11.1 %, p < 0.001).

Conclusions In this propensity-score-matched analysis of the largest AL-cohort so far, EP was associated with less complications and a lower initial R0-rate. In most cases, EA-retreatment finally resulted in complete resection.
