Peripheral sentinel lymphadenectomy in 163 dogs: Postoperative surgical complications and comparison between intraoperative dissection techniques.
Article in Veterinary surgery : VS, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectiveThe first aim was to describe the incidence and severity of surgical complications following peripheral lymphadenectomy in dogs. The second was to compare three surgical techniques: unassisted lymphadenectomy, intraoperative guidance by methylene blue dye alone (MB) or by a combination of γ-probe and MB (γ-MB). The third was to assess whether the number, palpability, and site of lymph nodes (LNs) influenced the incidence of complications. STUDY
designRetrospective multicenter study. SAMPLE POPULATION: Lymphadenectomies (n = 201) from 163 client-owned tumor-bearing dogs.
methodsMedical records of dogs undergoing both preoperative sentinel LN (SLN) mapping and excision of peripheral SLNs between December 2020 and April 2023 were reviewed. Signalment, intraoperative assistance technique, number of LNs, surgical time, postoperative treatments, site, and timing of complications observed were collected.
resultsSeventy-two (36%) lymphadenectomies were performed without assistance, 24% with MB and 40% with γ-MB. The overall incidence of surgical complications was 7.5%, of which 80% were mild. The most frequent complication was seroma (2.5%). None of the variables considered in the logistic regression model, including intraoperative guidance, influenced the complication rate (p = .255). Using the decision tree statistical model, mandibular and retropharyngeal lymphadenectomy affected the complication rate when surgery lasted more than 21.5 min.
conclusionLymphadenectomy of peripheral LNs was associated with a low rate of mild complications, regardless of intraoperative assistance. Mandibular and retropharyngeal lymphadenectomies lasting more than 21.5 min may result in more complications. CLINICAL SIGNIFICANCE: Lymphadenectomy of superficial LNs is a safe procedure that is easy to perform in most cases, even without intraoperative assistance.
