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.

Abstract

backgroundThe use of laparoscopy for right hemicolectomy has gained popularity allowing the option of a totally laparoscopic intracorporeal anastomosis (IA) for intestinal reconstruction. This technique may alleviate some of the technical limitations that a surgeon faces with a laparoscopic-assisted extracorporeal anastomosis (EA).

methodsA retrospective chart review of 195 consecutive patients who underwent laparoscopic right hemicolectomy by four colorectal surgeons at three institutions from March 2005 to June 2014 was performed. Multivariate regression analysis was used to compare postoperative and oncologic outcomes.

resultsA total of 195 patients underwent laparoscopic right hemicolectomy over the study period, with 86 (44 %) patients receiving IA and 109 (56 %) patients receiving an EA. The most common indication for surgery in both groups was cancer: 56 (65 %) of IA cases and 57 (52 %) of EA cases. IA had a significantly higher rate of minor complications but no difference in serious complications compared to EA. Conversion to open resection was higher in EA. Using multivariate analysis to compare IA versus EA, there was no significant difference in length of stay, return of bowel function, risk of anastomotic leak, risk of intraabdominal abscess or risk of wound complications. Amongst cancer resections, there was no significant difference in the median number of lymph nodes harvested (18 LNs in IA group vs. 19 LNs in EA group, P > 0.05). There was also no significant difference in overall survival and disease-free survival at 5.7 years between the two groups.

conclusionsIA in laparoscopic right hemicolectomy is associated with similar postoperative and oncologic outcomes compared to EA. IA may possess advantages in terms of conversion and flexibility of specimen extraction, but this is counterbalanced by a higher incidence of minor complications. These findings suggest that IA represents a valid technique in the arsenal of the experienced colorectal surgeon without compromising outcomes.
