Standardized operating reports were reviewed regarding: (a) intraoperative bile leakage observed during the routinely performed \u2018HJ gauze test,\u2019 (b) multiple HJ anastomoses, (c) joined bile ducts, or (d) placement of a HJ stent. Bile leakage was managed intraoperatively by additional direct sutures or, if not deemed safe, by anchoring sutures between the jejunum and the hilar plate.

The routinely performed intraoperative \u2018HJ gauze test\u2019 detected bile leakage in 21 (9%) patients, all of whom underwent intraoperative surgical repair: 13 (62%) direct sutures and 8 (38%) anchoring sutures to the hilar plate. In these patients, postoperative bile leakage occurred in 3\/21 (14%) patients with 0\/21 (0%) mortality. Overall, 5 (2%) patients received two HJs, and 8 (3%) patients received a stent in the HJ with 0\/11 (0%) bile leakage. Patients with intraoperative findings of bile leakage had a non-significant higher rate of postoperative bile leakage (3 patients [14%] vs 12 patients [6%]) (OR 2.83, 95% CI 0.47 to 11.91, Fisher\u2019s exact test\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.12).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Routine use of the \u2018HJ gauze test\u2019 during RPD may be useful to detect intraoperative bile leakage, with similar outcomes after intraoperative repair (either with direct sutures or anchoring sutures).
