1 · What the graph read from 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.

2 · The registry

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

purposeSingle-port plus one-port, reduced-port laparoscopic surgery (RPLS) may decrease collisions between laparoscopic instruments and the camera in a narrow, bony, pelvic cavity while maintaining the cosmetic advantages of single-incision laparoscopic surgery. The aim of this study is to describe our initial experience with and to assess the feasibility and safety of RPLS for tumor-specific mesorectal excisions (TSMEs) in patients with colorectal cancer.

methodsBetween May 2010 and August 2012, RPLS for TSME was performed in 20 patients with colorectal cancer. A single port with four channels through an umbilical incision and an additional port in the right lower quadrant were used for RPLS.

resultsThe median operation time was 231 minutes (range, 160-347 minutes), and the estimated blood loss was 100 mL (range, 50-500 mL). We transected the rectum with one laparoscopic stapler in 17 cases (85%). The median time to soft diet was 4 days (range, 3-6 days), and the length of hospital stay was 7 days (range, 5-45 days). The median total number of lymph nodes harvested was 16 (range, 7-36), and circumferential resection margin involvement was found in 1 case (5%). Seven patients (35%) developed postoperative complications, and no mortalities occurred within 30 days. During the median follow-up period of 20 months (range, 12-40 months), liver metastasis occurred in 1 patient 10 months after surgery, and local recurrence was nonexistent.

conclusionRPLS for TSME in patients with colorectal cancer is technically feasible and safe without compromising oncologic safety. However, further studies comparing RPLS with a conventional, laparoscopic low-anterior resection are needed to prove the advantages of the RPLS procedure.
