Transverse versus longitudinal skin incisions for totally implantable venous access port implantation: a randomized controlled trial.
Trial report in Langenbeck's archives of surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06766656 (Comparison of Transverse and Longitudinal Incisions for Venous Access Port Placement), which is not on this map. Not yet cited in PubMed.
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.

Abstract
backgroundTotally implantable venous access ports (TIVAPs) are widely used in oncologic patients requiring long-term vascular access. However, the impact of skin incision orientation on postprocedural pain, procedural efficiency, and early complications remains unclear. This study compared transverse and longitudinal incisions in terms of early postoperative pain, patient-reported discomfort, procedure duration, and complication rates.
methodsIn this randomized, single-center study, 170 patients undergoing TIVAP implantation were assigned to either a transverse or longitudinal incision group (85 patients each). All procedures followed a standardized protocol with ultrasound-guided venous access and fluoroscopic confirmation of catheter tip position. Pain intensity was assessed using the numeric rating scale (NRS) within 24 h, and patient-reported discomfort was evaluated on day 7. Procedural characteristics and early complications were recorded.
resultsPostprocedural pain was low in both groups, with most patients reporting NRS scores between 0 and 2. Analgesic requirements were minimal, with no significant between-group differences. Discomfort at day 7 was also low and comparable. Procedure duration showed a trend toward shorter times in the transverse incision group [20 (18; 30) vs. 25 (20; 35) minutes; p = 0.09]. Overall complication rates were low, with no major complications. Minor complications included local inflammatory reactions and hematomas. Bleeding within the port pocket was more frequent in the longitudinal incision group, although not statistically significant.
conclusionsTransverse and longitudinal incisions provide comparable outcomes in TIVAP implantation, with low pain, minimal discomfort, and low complication rates. A trend toward shorter procedure duration and less port pocket bleeding with transverse incisions suggests potential technical advantages.
