Postoperative Complications and Risk Factors in Skin Tumor Excision With Simple Suturing Under Local Anesthesia: A Multicenter Retrospective Study in Japan.
Observational study in The Journal of dermatology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Skin tumor excision under local anesthesia with simple suturing is widely performed in outpatient dermatological practice. Although generally considered safe, postoperative complications such as wound dehiscence, infection, and contact dermatitis can negatively impact patients' quality of life and healthcare resources. However, limited data are available on the complication rates and associated risk factors in procedures without reconstructive techniques. We retrospectively analyzed 1291 patients who underwent local excision and simple closure of skin tumors at three institutions in Japan between January 2021 and November 2024. Complications were defined as adverse events requiring medical intervention within 30 days postoperatively. Receiver operating characteristic curves were used to determine the cutoff values for age, tumor size, operative time, and surgeon experience. Logistic regression analysis was performed to identify independent risk factors. A total of 168 complications occurred in 164 patients (12.7%). The most common symptoms were contact dermatitis (3.7%), wound dehiscence (3.3%), and surgical site infection (2.9%). Multivariate analysis revealed tumor size ≥ 10 mm (odds ratio [OR] 1.52, p = 0.040), operative time ≥ 38 min (OR 1.84, p = 0.012), and surgeon experience ≥ 10 years (OR 1.64, p = 0.013) as significant risk factors. In contrast, intraoperative antibiotic use significantly reduced complication risks (OR 0.29, p < 0.001), especially the risk of surgical site infections (OR 0.32, p = 0.024). No serious or life-threatening events occurred. This study identified key predictors of postoperative complications in skin tumor surgery performed under local anesthesia. Larger tumors, longer operative times, and more experienced surgeons were associated with a higher risk, possibly because of the procedural complexity. Prophylactic intraoperative antibiotics effectively reduce infections and should be considered in high-risk cases. These findings support evidence-based risk assessment and perioperative management of dermatological surgery.
