Laparoscopic enterolithotomy for large gallstone ileus in an elderly high-risk patient: a case report.
Article in BMC 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
backgroundGallstone ileus is an uncommon complication of cholelithiasis leading to mechanical small bowel obstruction that typically affects geriatric populations with significant baseline medical conditions. The optimal management approach is highly debated, specifically when choosing between simple emergency enterolithotomy alone or a complex one-stage definitive biliary procedure in high-risk patients. CASE PRESENTATION: A 79-year-old male with an ECOG performance status of 2, ASA Class IV risk classification, and known severe ischemic heart disease presented with acute mechanical small bowel obstruction. Preoperative contrast-enhanced computed tomography (CT) and subsequent emergency laparoscopic exploration identified an oversized, calcified intraluminal gallstone measuring 7 × 4 cm impacted within the terminal ileum. A laparoscopic enterolithotomy was successfully performed without a concomitant biliary intervention. The immediate postoperative course was complicated by an acute non-ST-elevation myocardial infarction (NSTEMI) detected via postoperative ECG. Following successful stabilization, the patient recovered gastrointestinal function and was safely discharged home after one week with structured outpatient cardiology follow-up.
conclusionsThis case shows that an isolated laparoscopic enterolithotomy can serve as a technically feasible option for large gallstone ileus in selected high-risk patients when executed by experienced hands. However, clinicians must maintain extensive vigilance regarding perioperative cardiovascular strain, as the surgical resolution of obstruction must be balanced against severe potential cardiac complications.
