Intracorporeal or extracorporeal anastomosis after minimally invasive right colectomy: a systematic review and meta-analysis.

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
purposeAs part of the wide adoption of minimally invasive surgery, intracorporeal anastomosis is becoming increasingly common. The benefits of minimally invasive versus open right colectomy are well known although the additional benefits of an intracorporeal anastomosis, performed laparoscopically or robotically, are unclear. The aim of this study was to assess the current literature comparing intracorporeal and extracorporeal anastomosis in the setting of laparoscopic and robotic-assisted right colectomy.
methodsA systematic review and meta-analysis was conducted according to PRISMA and AMSTAR methods. Studies included were randomized controlled trials and prospective or retrospective cohort studies, between January 1 2010 and July 1 2021, comparing intracorporeal and extracorporeal anastomosis with laparoscopic and robotic approaches. Four groups were identified: laparoscopic extracorporeal anastomosis (L-ECA), laparoscopic intracorporeal anastomosis (L-ICA), robotic extracorporeal anastomosis (R-ECA), and robotic intracorporeal anastomosis (R-ICA). Operative time, rate of conversion to an open procedure, surgical site infection, reoperation within 30 days, postoperative complications within 30 days, and length of hospital stay were assessed.
resultsTwenty-one retrospective cohort studies were included in the final analysis. R-ICA and R-ECA had comparable operative times, but a robotic approach required more time than laparoscopic (68 min longer, p < 0.00001). Conversion to open surgery was 55% less likely in the R-ICA group vs. L-ICA, and up to 94% less likely in the R-ICA group in comparison to the R-ECA group. Length of hospital stay was shorter for R-ICA by a half day vs. R-ECA, and up to 1 day less vs. L-ECA. There were no differences in postoperative complications, reoperations, or surgical site infections, regardless of approach. However, the included studies all had high risks of bias due to confounding variables and patient selection.
conclusionRobotic-assisted right colectomy with intracorporeal anastomosis was associated with shorter length of hospitalization and decreased rate of conversion to open surgery, compared to either laparoscopic or extracorporeal robotic approaches. Prospective studies are needed to better understand the true impact of robotic approach and intracorporeal anastomosis in right colectomy.
