Endoscopic sleeve gastroplasty versus single anastomosis sleeve ileal bypass: a single-center experience.
Article in BMC surgery, 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
backgroundEndoscopic sleeve gastroplasty (ESG) is a minimally invasive procedure that is less effective for weight loss. Single anastomosis sleeve ileal bypass (SASI) combines sleeve gastrectomy with an ileal bypass to maximize weight loss. We compared the postoperative results of ESG vs. SASI at 6 months to evaluate weight reduction and nutritional outcomes.
methodsThis retrospective study included 21 patients. Body weight and levels of serum iron, calcium, zinc, vitamin B12, and folate were measured preoperatively and at 1, 3, and 6 months postoperatively. The SASI group received postoperative supplementation of vitamin B12, folate, calcium, and ferritin, whereas the ESG group did not. Statistical analyses assessed changes within and between groups.
resultsAt 6 months post-surgery, weight loss was greater in the SASI group. Although iron levels in both groups declined at 1 month post-surgery, they returned to baseline levels at 6 months. At 3 and 6 months post-surgery, the ESG group had a slight decrease in calcium levels, whereas the SASI group showed a significant decrease in zinc levels. No vitamin B12 or folate deficiencies were observed. At 6 months post-surgery, changes in micronutrient levels were comparable between the groups. The operative time and hospital stay were longer in the SASI group.
conclusionSASI achieved greater weight loss at 6 months post-surgery than ESG but required a longer operative time and hospitalization. With appropriate supplementation, short-term nutritional outcomes were similar in both groups. Long-term monitoring for iron and B12 deficiency is required following SASI.
