PurposeThe aim of the current study was to evaluate the adverse clinical impact of intraoperative conversion during laparoscopic pancreaticoduodenectomy (LPD).Materials And MethodsThe medical records of patients who underwent pancreaticoduodenectomy (PD) were retrospectively reviewed. Perioperative clinical variables were compared between patients who underwent converted PD (cPD) and initially planned open PD (OPD) to investigate the clinical impact and predictive factors of intraoperative conversion during LPD.ResultsA total of 171 patients were included. Among them, 31 patients (19.3%) were found to have intraoperative conversion during LPD. Failure of progression due to severe adhesion (12 patients, 7%) and major vessel invasion (7 patients, 4%) were the two most frequent reasons for conversion. On multivariate analysis, age [Exp(β)=1.044, p=0.044] and pancreatic texture [Expa(β)=2.431, p=0.039) were found to be independent factors for predicting intraoperative conversion during LPD. In comparative analysis with the OPD group, the cPD group had a longer operation time (516.8 min vs. 449.9 min, p=0.001), higher rate of postoperative hemorrhage (12.1% vs. 0.85%, p=0.008), higher reoperation rate (9.1% vs. 0%, p=0.01), and higher cost (21886.4 USD vs. 17168.9 USD, p=0.018).ConclusionIntraoperative conversion during LPD can have an adverse clinical impact on the postoperative course following LPD. Appropriate patients selection and improvement of surgical techniques will be crucial for unnecessary intraoperative conversion and safe LPD.© Copyright: Yonsei University College of Medicine 2021.
