Modified Kraske Procedure for retrorectal tumors: Early postoperative outcomes and surgical site infection rates in a single-center experience.
Observational study 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
objectiveThe aim of this study is to evaluate the early postoperative morbidity rates with a particular focus on surgical site infection rates, in patients undergoing resection for retrorectal tumors with the modified Kraske Procedure.
methodsThis descriptive observational case series study included patients who underwent resection for retrorectal tumors performing the modified Kraske Procedure between August 2006 and August 2025. Patients with recurrent disease or a history of pelvic radiotherapy or chemotherapy were excluded. The primary outcome was early postoperative morbidity, especially in terms of surgical site infections, which was defined as complications occurring within the first 30 days after surgery.
resultsAmong 35 patients operated for retrorectal tumors, 23 (65.7%) patients underwent a resection performing the modified Kraske Procedure and were included in the analysis. The majority of patients were female (82.6%), with a mean age of 40.3 ± 15.8 years. The mean tumor size was 42.5 ± 10.0 mm, and most lesions were benign (87%). Postoperative complications occurred in three (13%) patients, with surgical site infection observed in only one (4.3%) patient. The mean length of hospital stay was 3.8 ± 1.9 days.
conclusionThe modified Kraske Procedure was associated with a low surgical site infection rate and acceptable early postoperative morbidity in this series. This technique may represent a feasible surgical modification for selected retrorectal tumors and warrants further evaluation in comparative studies.
