Conversion rate in 300 laparoscopic rectal resections and its influence on morbidity and oncological outcome.
Article in International journal of colorectal disease, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 34 papers, 1 of them a synthesis that pooled it.
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
introductionThe negative influence of conversion from laparoscopic to open colorectal resection on early postoperative morbidity and outcome has been demonstrated several times. In this study, we analyzed the conversion rate and its influence on early postoperative morbidity and short-term oncological outcome following laparoscopic rectal resections.
methodsFrom January 1998 to December 2006, 300 patients underwent laparoscopic resection due to rectal carcinoma at our institution. We compared the converted patient group with the non-converted patient group regarding demographical, clinical, surgical, and histological data, compounded with the early and late postoperative results.
resultsTwo hundred seventy-four (91.3%) patients underwent laparoscopic rectal resection (LR), while conversion resection (CR) was necessary in 26 cases (8.6%). Conversion rate was 13% during the first 100 resections and decreased to 3% during the last 100 procedures (p = 0.035). Male gender, higher body mass index, and presence of T4-tumor were risk factors for conversion. Early postoperative complications were more frequent in the CR group than in the LR group. Concerning local tumor recurrence and overall survival, there was no significant difference between both groups (local recurrence, CR at 3.8% vs. LR at 4.5% and overall survival rate, CR at 76.9% vs. LR at 89.1%) after a median follow-up period of 22.5 months.
conclusionConversion to an open procedure during laparoscopic rectal resection correlates with an increased postoperative morbidity, however, without impairment of the short-term oncological outcome. The conversion rate is minimized by the growing experience of the operating surgeon and, therefore, is a marker of the learning curve.
