Risk factors and outcomes of renal insufficiency after colectomy for diverticulitis.
Article in Techniques in coloproctology, 2024. 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
backgroundDiverticulitis has significantly increased in prevalence in recent decades, requiring higher rates of colon resections. While current literature focuses on postoperative complications such as abscesses, wound infections, and anastomotic leaks, many are limited in showing details regarding the significant risk associated with developing renal insufficiency among diverticulitis patients undergoing colectomy.
methodsWe selected patients from the 2022 National Surgical Quality Improvement Program (NSQIP) Colectomy database who underwent colon resection for diverticulitis using International Classification of Disease (ICD10) code K57.92. To analyze postoperative renal function, we removed all patients with preoperative renal failure. From there, a total of 6985 patients with no postoperative renal insufficiency (Control group) and 492 with postoperative renal insufficiency (Post-op. RI group) were identified.
resultsOf individuals undergoing colectomy for diverticulitis, 6.58% experienced postoperative renal insufficiency. In all diverticulitis colectomies, comorbidities such as diabetes (21.95% versus 10.95%; p = 0.018), congestive heart failure (11.59% versus 2.95% p < 0.001), hypertension (61.79% versus 42.83%; p < 0.001), and chronic obstructive pulmonary disease (9.96% versus 3.66%; p < 0.001) were associated with higher risk of kidney injury. Multivariate regression analysis indicated that postoperative renal insufficiency is independently associated with increased risk of mortality (odds ratio = 3.8001; p < 0.001).
conclusionsAs the prevalence of diverticulitis has increased in the USA, it is paramount to recognize the risks associated with the required operation as well as the factors that affect patient outcomes and risks for developing renal insufficiency.
