Totally laparoscopic anatomic S7 segmentectomy using in situ split along the right intersectoral and intersegmental planes.
Article in Surgical endoscopy, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
backgroundThe traditional open or laparoscopic segmentectomy of liver segment 7 (S7) requires exposing and controlling the root of the right hepatic vein(RHV)after full mobilization and lifting up of the right liver before liver transection. This approach violates the "no-touch" principle for malignant tumors, and makes laparoscopic resection technically challenging. So reports on isolated totally laparoscopic anatomic S7 segmentectomy have rarely been reported. This study describes our experience in laparoscopic anatomic S7 segmentectomy using in situ split along the right intersectoral and intersegmental planes of the liver. To our knowledge, this is the first description of this novel approach.
methodsFrom September 2017 to May 2019, patients who underwent laparoscopic anatomic S7 segmentectomy for hepatocellular carcinoma at the HPB Surgery Department, Sun Yat-Sen Memorial Hospital entered into this retrospective study. This in situ split approach was designed using main vessels as the plane markers of right intersectoral and intersegmental planes, along which liver transection was carried out. There was no need to mobilize the right liver and control the root of RHV.
resultsThere were 9 women and 15 men. The average diameter of the tumors on preoperative CT/MR was 3.4 cm (range 2-6 cm). All the procedures were successfully carried out laparoscopically. There was no perioperative death. The average operative time was 216.5 min (range 180-310 min). The average blood loss was 320 ml (range 120-620 ml). Pathological study showed all the operations to be R0 resections.
conclusionLaparoscopic anatomic S7 segmentectomy using the in situ split approach resulted in R0 liver resection in all our patients with primary liver cancer. The operation was technically feasible and it provided a better view and increased maneuverability in the cramped operative space compared with the traditional open/laparoscopic approach. The approach also better complies with the "no-touch" principle for malignant tumors. Its long-term oncological outcomes require further studies.
