Hepaticojejunostomy bile leakage and aberrant biliary anatomy during robotic pancreatoduodenectomy: intraoperative detection and management.
Article in Surgical endoscopy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundBile leakage from the hepatico-jejunostomy (HJ) is a rare but potentially lethal complication during robotic pancreatoduodenectomy (RPD). The rate of intraoperatively detected bile leakage from the HJ and aberrant biliary anatomy during RPD and its optimal management remains unclear.
methodsThis retrospective and exploratory cohort study included all adult patients undergoing RPD at a single high-volume center (December 2018-March 2025). Standardized operating reports were reviewed regarding: (a) intraoperative bile leakage observed during the routinely performed 'HJ gauze test,' (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. Only ISGLS bile leakage grade B/C was included.
resultsOverall, 238 patients undergoing RPD were included. The routinely performed intraoperative 'HJ gauze test' 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's exact test p = 0.12).
conclusionRoutine use of the 'HJ gauze test' during RPD may be useful to detect intraoperative bile leakage, with similar outcomes after intraoperative repair (either with direct sutures or anchoring sutures). Non-standard HJ constructions and bile duct anatomy variants were rare.
