Modern Trends of Drain Placement in Primary Bariatric Surgery: An MBSAQIP Analysis of 526,723 Patients.
Article in Obesity surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundProphylactic drain use during primary bariatric surgeries continues despite previous literature cautioning against their routine use. Modern drain utilization and associated outcomes remain largely poorly studied which limits selective utilization and perhaps may lead to excess morbidity and healthcare resource utilization. This study aimed to reassess current trends of drain use in primary bariatric procedures, factors driving surgeons to place drains, and patient outcomes associated with drain placement.
methodsPatients undergoing the most common primary bariatric surgery operations from 2020 to 2022 were included using the Metabolic and Bariatric Accreditation and Quality Improvement Program (MBSAQIP) database. Two cohorts were created, a drain placed (DP) cohort and no drain (ND) cohort, which were then compared in terms of baseline characteristics, rates of complications, and length of stay. Multivariate modeling was performed to assess the effect of drains on various complications and factors associated with drain placement.
resultsOf 526,723 included patients, drain utilization decreased across operative years (8.7% in 2020 to 6.1% in 2022, p < 0.001). Factors associated with drain placement in multivariate models included older age, higher BMI, partially dependent functional status, renal insufficiency, venous thromboembolism, hypoalbuminemia, and non-sleeve anastomotic procedures. Drain placement was associated with increased risk of numerous complications on bivariate analysis, which was still significant in multivariate analysis, including 30-day serious complications (adjusted odds ratio [aOR] 1.24, p < 0.001), anastomotic leak (aOR 2.1, p < 0.001), organ space infection (aOR 2.0, p < 0.001), reoperation (aOR 1.2, p = 0.036), and excess length of stay (LOS, aOR 1.45, p < 0.001).
conclusionsThe frequency of prophylactic drain placement during primary bariatric surgical procedures has decreased in recent years and patients with drain placement seem to have increased 30-day morbidity, including longer length of stay. Independent predictors of drain placement include increased age and metabolic burden along with anastomotic procedures. Surgeons should be judicious in selecting patients for drain placement and future prospective, controlled studies may better answer drain placement association with complications.
