Postpancreatectomy diarrhoea: prospective, single-centre longitudinal analysis of incidence, risk factors, management, and impact on quality of life.
Article in BJS open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
backgroundPostpancreatectomy diarrhoea significantly impairs outcomes and patient's quality of life. Its origin is multifactorial, extending beyond exocrine pancreatic insufficiency. Even with pancreatic enzyme replacement therapy, persistent postpancreatectomy diarrhoea can lead to malnutrition and inhibit adjuvant treatments. This study aimed to evaluate the incidence, risk factors, management, and impact of postpancreatectomy diarrhoea on quality of life.
methodsThis prospective longitudinal study enrolled patients undergoing pancreatectomy at a single tertiary centre from 2023 to 2025. After surgery (at 7, 30, and 90 days), an adapted systemic therapy-induced diarrhoea assessment tool (STIDAT) questionnaire was used to assess for the presence of postpancreatectomy diarrhoea, patient-reported severity, frequency, medication use, associated symptoms, and quality of life.
resultsA total of 237 patients were included (pancreatoduodenectomy 54%, distal pancreatectomy 35%, total pancreatectomy 11%). Overall, the incidence of postpancreatectomy diarrhoea was 32, 41, and 33% at 7, 30, and 90 days, respectively. Postpancreatectomy diarrhoea was most frequent and severe after total pancreatectomy and pancreatoduodenectomy (62 and 50% at 30 days) and least after distal pancreatectomy (22.0% at 30 days) (P < 0.001). The severity of postpancreatectomy diarrhoea correlated with worse quality of life and higher STIDAT scores at all time points. Most patients with postpancreatectomy diarrhoea required pancreatic enzyme replacement therapy, with a median dose of 85 000 lipase units per day by 90 days, and up to 37% also needed antidiarrhoeals. Common 30-day symptoms included urgency (52%), abdominal discomfort (69.4%), and incontinence (18.4%). In multivariable analysis, pancreatic ductal adenocarcinoma, vascular resection, and arterial divestment were independent predictors of moderate-to-severe postpancreatectomy diarrhoea, whereas distal pancreatectomy was protective.
conclusionPostpancreatectomy diarrhoea is an impactful complication after pancreatectomy, affecting more than one-third of patients even after correct pancreatic enzyme replacement therapy. Patients undergoing vascular resection and arterial divestment are at higher risk of severe postpancreatectomy diarrhoea, and require tailored postoperative management to reduce its negative effects, which include impaired quality of life.
