Postoperative hospitalization time in laparoscopic and laparotomic Roux-En-Y gastric bypass: a retrospective observational cohort study.
Observational study in Arquivos brasileiros de cirurgia digestiva : ABCD = Brazilian archives of digestive surgery, 2026. 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
backgroundObesity is a growing problem both in Brazil and worldwide, and bariatric surgery is a well-established method for reducing weight and, consequently, reducing the risk of death attributed to cardiovascular and metabolic problems. Roux-en-Y gastric bypass is currently the most popular surgical technique in Brazil, performed via either laparotomy or laparoscopy.
aimsTo compare the length of hospital stay after Roux-en-Y gastric bypass performed via laparoscopic and laparotomic approaches.
methodsAn observational study using retrospective data from medical records, comparing patients who underwent Roux-en-Y gastric bypass by laparoscopy and patients operated on by laparotomy, with similar comorbidities.
resultsThe sample consisted of 64 patients who underwent surgery: 31 via laparoscopy and 33 via laparotomy, of whom 84.4% were female, with a mean age of 44.1 (SD=10.1). 15.6% were male, with a mean age of 40.2 (SD=13.3). Among the four variables evaluated (sex, age, length of hospital stay, and type of surgery), the only statistically significant difference found was in the length of hospital stay according to each type of surgery, with patients undergoing Roux-en-Y gastroplasty via laparoscopic approach remaining hospitalized for a mean of 2.45 days (SD=1.12), while those undergoing the same surgery via laparotomic approach remained hospitalized for a mean of 3.42 days (SD=1.17).
conclusionsThe findings of this study indicate a numerically and statistically significant difference in length of hospital stay between both surgical access routes for bariatric surgery, with a shorter stay observed in the laparoscopic approach. This information is relevant, as it has financial impact by reducing bed occupancy time and the costs arising from hospitalization.
