Clinical profile and treatment outcome of patients with ileo-sigmoid knotting, an experience from Ethiopian setting: a six years review.
Article in BMC 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
backgroundIleo-sigmoid knotting (ISK) is a rare cause of intestinal obstruction, characterized by the twisting of the ileum around the sigmoid colon or vice versa. This study aimed to assess the clinical characteristics and treatment outcomes of patients undergoing laparotomy for ISK at a tertiary hospital in Ethiopia.
methodsThis is an institution based cross sectional study conducted at Debre Markos Comprehensive Specialized Hospital in Debre Markos City, Northwest Ethiopia. A six-year study was conducted at Debre Markos Comprehensive Specialized Hospital by revewing the medical records of 42 patients operated for ISK between March 31, 2018, and April 1, 2024. Data were extracted, processed, and analyzed using Epi-Data 4.6 and STATA 17.0. Fisher's exact test was used to determine statistical significance (p-value ≤ 0.05).
resultsThirty-eight patients (90.5%) had complete medical records, with a mean age of 39.2 years (SD ± 10.2) and a male predominance (M: F = 3.2:1). Accurate preoperative diagnosis was achieved in only 5.3% of cases, with the majority being misdiagnosed as small or large bowel obstruction. Gangrene of both the ileum and sigmoid colon was observed in 71.1% of cases. The most commonly performed procedure (68.4%) was resection of both segments with primary ileo-ileal and colorectal anastomosis. Postoperative complications occurred in 52.6% of patients, the most common one being anemia (31.6%). Mortality was 7.9% and was significantly associated with anastomotic leaks (p = 0.045). The average hospital stay was 8.2 days (IQR: 6-37). CONCLUSIONS AND RECOMMENDATION: The accuracy of preoperative diagnosis of ileo-sigmoid knotting in this study is lower. However, ileo-sigmoid knotting had high postoperative morbidity and mortality. This study highlights the need for heightened awareness for preoperative diagnosis and prompt surgical treatment. We recommend a prospective multicentric study to guide on appropriate operative decision making in ISK patients.
