Mortality and complications in patients with obesity after open, robotic or laparoscopic pancreaticoduodenectomy: A systematic review and meta-analysis.
Synthesis in International journal of obesity (2005), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectivesThis meta-analysis compares outcomes of pancreaticoduodenectomy (PD) using open (OPD), robotic (RPD), and laparoscopic (LPD) techniques in patients with and without obesity and resectable pancreatic cancer.
methodsThirteen observational studies evaluating 30-day mortality and postoperative complications in patients that underwent PD were included. Outcomes included mortality, major complications (Clavien-Dindo classification), and specific surgical complications: postoperative pancreatic fistula (POPF), post-PD hemorrhage (PPH), delayed gastric emptying (DGE), and surgical site infections (SSI).
resultsPatients with obesity had higher 30-day mortality rates (2.42% vs. 1.63%; OR: 1.68, 95% CI: 1.35-2.08, p < 0.00001, I² = 0%) and major complications (23.3% vs. 17.12%; OR: 1.77, 95% CI: 1.27-2.46, p = 0.0007, I² = 52%) than patients without obesity. Obesity also increased the risk of POPF (21.9% vs. 13.76%; OR: 2.04, 95% CI: 1.69-2.46, p < 0.00001, I² = 26%), PPH (7.31% vs. 6.26%; OR: 1.44, 95% CI: 1.07-1.94, p = 0.02, I² = 0%), and DGE (20.23% vs. 15.5%; OR: 1.98, 95% CI: 1.3-3.03, p < 0.00001, I² = 89%). SSI risk trended higher in patients with obesity but was not statistically significant (28.17% vs. 20.39%; OR: 1.80, 95% CI: 0.93-3.5, p = 0.08, I² = 90%). Among surgical techniques, patients with obesity who underwent OPD had higher risks of 30-day mortality (OR: 1.59, 95% CI: 1.26-2.00, p < .0001), major complications (OR 1.63, 95% CI 1.17-2.28, p = 0.004), and POPF (OR 1.98, 95% CI 1.59-2.47, p < 0.00001) than patients without obesity. In the RPD group, obesity increased the risk of 30-day mortality (OR: 2.68, 95% CI: 1.12-6.39, p = 0.03) and POPF (OR 3.32, 95% CI 1.68-6.57, p = 0.0006). In LPD, obesity was associated with a higher risk of POPF (OR 2.06, 95%CI 1.69-3.32, p = 0.003).
conclusionsPatients with obesity undergoing PD are at increased risk for 30-day mortality and major complications. OPD carries the highest overall risk, while RPD and LPD are linked to a greater POPF risk. These findings highlight the need for careful perioperative management in this high-risk population.
