Standardized lymph node dissection for gallbladder cancer under laparoscopy: en-bloc resection technique.
Article in Langenbeck's archives of surgery, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
purposePositive lymph node (LN) is a key prognostic factor in radically resected gallbladder cancer (GBCA). However, only a few underwent an adequate lymphadenectomy, and the number and extent of lymph node dissection (LND) have not been standardized. This study aims to develop an en bloc and standardized surgical procedure of LND for GBCA under laparoscopy.
methodsData of patients with GBCA underwent laparoscopic radical resection using a standardized and en bloc technique for LND were collected. Perioperative and long-term outcomes were retrospectively analyzed.
resultsA total of 39 patients underwent laparoscopic radical resection using standardized and en bloc technique for LND except one case (open conversion rate: 2.6%). Patients with stage T1b had significantly lower LNs involved rate than patients with stage T3 (P = 0.04), whereas median LN count in stage T1b was significantly higher than that in stage T2 (P = 0.04), which was significantly higher than that in stage T3 (P = 0.02). Lymphadenectomy with ≥ 6 LNs accounted for 87.5% in stage T1b, up to 93.3% in T2 and 81.3% in T3, respectively. All the patients in stage T1b were alive without recurrence at this writing. The 2-year recurrence-free survival rate was 80% for T2 and 25% for T3, and the 3-year overall survival rate was 73.3% for T2 and 37.5% for T3.
conclusionThe standardized and en bloc LND permits complete and radical removal of lymph stations for patients with GBCA. This technique is safe and feasible with low complication rates and good prognosis. Further studies are required to explore its value and long-term outcomes compared to conventional approaches.
