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

backgroundLaparoscopic liver resection (LLR) has undergone widespread dissemination after the first international consensus conference in 2008, and specialized centers continue to report remarkable achievements. However, little is known about the global adoption of LLR. This study aimed to illuminate geographical variances in the indications and technical aspects of LLR and to delineate the evolution of this approach worldwide.

methodsIn advance of the Second International Consensus Conference in Morioka, Japan, a web-based, anonymous questionnaire comprising 46 questions, named the International Survey on Technical Aspects of Laparoscopic Liver Resection study, was sent via e-mail to the members of regional and International Hepato-Pancreato-Biliary Association offices. The results of the 13 questions concerning the global diffusion of LLR have been reported previously. Responses to the remaining 33 questions that corresponded to indications and surgical techniques used in LLR were collected and analyzed.

resultsSurvey responses were received from 412 LLR surgeons in 42 countries on five continents. The majority of surgeons in North America had no restrictions on the maximum size or number of tumors to be resected laparoscopically. Likewise, >50 % of surgeons in East Asia and North America performed LLR for the postero-superior 'difficult' segments. Major resection was performed in 40 to >60 % of centers in North America, Europe, and East Asia. Donor hepatectomy was performed only in specialized centers. More than 75 % of respondents had adopted a pure laparoscopic approach. A flexible laparoscope was most commonly used in East Asia. Most surgeons used pneumoperitoneal pressure at around 9-16 mmHg. Other techniques and devices were used at the discretion of each surgeon.

conclusionsIndications for LLR continue to expand with some regional diversity. Surgical approaches and devices used in LLR are a matter of preference and availability, as in open liver resection.
