RESUMEN
AIM: To compare peri-operative outcomes of skin closure with octyl cyanoacrylate (OCA) skin adhesive (Dermabond) with or without subcuticular sutures after deep dermal suturing for implantable venous port placement closure. MATERIALS AND METHODS: Seven hundred and ninety-two single-lumen implantable venous port insertions for chemotherapy were reviewed from September 2019 to March 2021 in a retrospective single-centre study. Propensity-score matching by a 1:1 nearest neighbour algorithm was conducted to control for confounding baseline differences. Distances were determined by logistic regression. Propensity-score matching was performed based on the following variables: age at procedure, gender, race, operator's seniority, use of anchoring polypropylene suture (PROLENE), port model, and volume of intra-operative local analgesia. The primary outcome was wound dehiscence at the first follow-up (â¼1 week). RESULTS: The 792 port insertions were conducted in 302 males (38.1%), median age 63 years (IQR: 54-69). Of the 656 wounds closed with subcuticular sutures and skin adhesive, 136 were matched in a 1:1 fashion against procedures closed without a subcuticular suture. No significant differences were demonstrated in pain scores, bleeding, swelling, bruising, fever, wound dehiscence, and discharge at postoperative day 1 (POD1) and at first follow-up between the groups (all p>0.05). Of note, no significant differences in wound dehiscence at first follow-up was found in both unmatched (p=0.133) and matched cohorts (McNemar-Bowker's χ2 = 1.167, p=0.761). CONCLUSION: These findings suggest that the omission of subcuticular sutures during implantable venous port closure may not compromise peri-operative outcomes when OCA skin adhesives were used.

AIM: To examine the relationship between catheter tip location and catheter dysfunction in the context of tunnelled central venous catheters (CVCs) for haemodialysis. MATERIALS AND METHODS: This was a retrospective study of 993 haemodialysis patients who underwent insertion of tunnelled CVCs of step-tip design via the right internal jugular vein (IJV). Based on intra-procedural radiographs, the catheter tip was characterised as being in the superior vena cava (SVC), cavo-atrial junction (CAJ), or deep right atrium (DRA). Patients were tracked for 90 days post-procedure for complications resulting in catheter replacement, and these were compared between cohorts. Statistical analysis was performed with Pearson's chi-square and Fisher's exact tests for categorical variables and two-sample t-test and one-way analysis of variance (ANOVA) for continuous variables. RESULTS: Ninety-five patients (9.6%) experienced catheter dysfunction necessitating replacement within 90 days of insertion. Tip location in SVC was associated with lower occurrence of catheter dysfunction (1.9%) as compared with the CAJ (8%) and DRA (11%; p=0.049). Catheter replacement due to other complications (catheter-associated bacteraemia, cuff dislodgement, exit-site infection, external catheter damage) showed no statistically significant relation to location of the CVC tip. CONCLUSION: When utilising tunnelled CVCs with a step-tip design inserted via the right IJV, location of the catheter tip in the SVC is associated with reduced occurrence of catheter dysfunction as compared to either the CAJ or DRA.
