Panniculectomy: an alternative approach to the revision of a difficult stoma.

AIM: We describe a modified abdominoplasty technique as an alternative approach to the revision of a difficult stoma. METHOD: A patient with a retracted colostomy secondary to change in abdominal wall contour following significant weight loss was treated with this technique. The patient had previous colostomy revision with marlex mesh insertion for combined parastomal and massive ventral hernia repair. A preoperatively marked crescent shaped left upper quadrant segment of skin and subcutaneous fat was excised and the defect was approximated in multiple layers. This shifted the stoma opening cephalad and eliminated the cutaneous crease that originally made it difficult to obtain a proper stoma seal. RESULTS: At one year follow up the patient was extremely satisfied with the results and was able to properly pouch the stoma. CONCLUSION: Modified abdominoplasty can be used as an alternative, low morbid approach in dealing with selected patients with difficult stoma problems.

A randomized, clinical trial comparing butylcyanoacrylate with octylcyanoacrylate in the management of selected pediatric facial lacerations.

OBJECTIVE: To compare two tissue adhesives, butylcyanoacrylate and octylcyanoacrylate, in the treatment of small (<4 cm) superficial linear traumatic facial lacerations in children. METHODS: This was a randomized, clinical trial with parallel design. 94 children <18 years of age seen in the ED of a tertiary care pediatric hospital with a facial laceration suitable for tissue adhesive closure underwent laceration closure using either butylcyanoacrylate or octylcyanoacrylate. The primary outcome was the cosmetic result at three months rated from photographs by a plastic surgeon on a visual analog scale (VAS). Secondary outcomes included the time to perform the procedure, the perceived difficulty of the procedure, the pain perceived by the patient, and a wound evaluation score at ten to 14 days and three months. RESULTS: Ninety-four patients were randomized with 47 in each group. The two groups were similar for baseline demographic and clinical characteristics. There was no difference in the three-month cosmesis VAS (median, 70.0 mm for n-butyl-2-cyanoacrylate vs 67.5 mm for octylcyanocrylate, p = 0.84). There was no difference between the groups for time to complete the procedure (p = 0.88), parent/patient-perceived pain of the procedure (p = 0.37), or physician-perceived difficulty of the procedure (p = 0.33). Similarly, there was no difference between the groups for the percentage of early (p = 0.58) or late (p = 0.71) optimal wound evaluation scores. CONCLUSIONS: In the closure of small linear pediatric facial lacerations, octylcyanoacrylate is similar to butylcyanoacrylate in ease of use and early and late cosmetic outcomes. The superior physical properties of octylcyanoacrylate appear to add little benefit to the management of these selected lacerations. Physician preference and differing costs may dictate use for these small selected lacerations.

Tissue adhesive versus suture wound repair at 1 year: randomized clinical trial correlating early, 3-month, and 1-year cosmetic outcome.

STUDY OBJECTIVE: To compare the 1-year cosmetic outcome of wounds treated with octylcyanoacrylate tissue adhesive and monofilament sutures and to correlate the early, 3-month, and 1-year cosmetic outcomes. METHODS: We prospectively randomized 136 cases of traumatic laceration to repair with octylcyanoacrylate tissue adhesive or 5-0 or smaller monofilament suture. A wound score was assigned by a research nurse, and validated by a second nurse blinded to the treatment, at 5 to 10 days after injury (early), 3 months, and 1 year. Standardized photographs were taken at 3 months and 1 year and shown to a cosmetic surgeon blinded to the method of closure, who rated the wounds on a validated cosmesis scale. RESULTS: We were able to examine 77 lacerations at 1 year for follow-up. No differences were found in the demographic or clinical characteristics between groups. Likewise, at 1 year no difference was found in the optimal wound scores (73% versus 68%, P =.60) or in visual analog scale cosmesis scores (69 versus 69 mm, P =.95) for octylcyanoacrylate and sutures, respectively. Agreement was poor between early and 3-month wound scores (kappa=.34; 95% confidence interval [CI],.10 to.58) but a strong association existed between 3-month and 1-year wound scores (kappa=.71; 95% CI,.52 to.90). We noted a moderate correlation between 3-month and 1-year results on the visual analog cosmesis scale (intraclass correlation,.48; 95% CI, .30 to.63). CONCLUSION: One year after wound repair, no difference is noted in the cosmetic outcomes of traumatic lacerations treated with octylcyanoacrylate tissue adhesive and sutures. The assessment of wounds 3 months after injury and wound repair provides a good measure of long-term cosmetic outcome.

A randomized trial comparing octylcyanoacrylate tissue adhesive and sutures in the management of lacerations.

OBJECTIVE: To assess the effectiveness of a new tissue adhesive for laceration closure. DESIGN: A prospective, randomized controlled trial. SETTING: An adult teaching hospital. PARTICIPANTS: One hundred thirty patients with 136 lacerations who consented to enrollment during a 5-month period. The lacerations included all eligible nonmucosal facial lacerations, as well as selected extremity and torso lacerations (not on hands, feet, or joints). One hundred six lacerations were available for early follow-up, and 98 were available for 3-month evaluation. INTERVENTIONS: Lacerations were randomly allocated to have skin closure with octylcyanoacrylate adhesive or monofilament suture. MAIN OUTCOME MEASURE: A 3-month photograph of the wound was assigned a cosmesis score on a previously validated 100-mm visual analog cosmesis scale by a plastic surgeon who was unaware of the method of wound closure. RESULTS: There were no differences in the mean visual analog cosmesis scores (67 mm for octylcyanoacrylate vs 68 mm for sutures; P=.65). Similarly, there was no difference in the percentage of early (80% vs 82%; P=.80) or late (72% vs 75%; P=.74) optimal wound evaluation scores. The tissue adhesive was a faster method of wound repair (3.6 vs 12.4 minutes; P<.001) as well as being less painful (visual analog pain scores, 7.2 vs 18.0 mm; P<.001). CONCLUSIONS: Octylcyanoacrylate tissue adhesive effectively closes selected lacerations. This relatively painless and fast method of wound repair can replace the need for suturing several million lacerations each year.

The effect of carbon dioxide laser on wound contraction and epithelial regeneration in rabbits.

This study was undertaken to compare objectively healing rates (in rabbits) of wounds caused by CO2 laser with those caused by scalpel. The rates of contraction and epithelialisation of standard wounds were determined with daily measurement of wound area from the time of wounding until the wound had healed. Our results demonstrate significant delays in both wound contraction (p = 0.0001) and epithelialisation (p = 0.0001) for CO2 laser-created wounds when compared to those seen in scalpel-created wounds. Normal epithelial regenerative capacities were demonstrated in the laser group despite the slow onset of epithelial migration. The appearance of the healed areas appeared comparable for both modalities.

Wound sterilization: CO2 laser versus iodine.

Control of infection in a surgical wound remains a challenge, especially if further surgery in the area is needed. This study was designed to compare the effectiveness of sterilization of a standard experimental infected wound by surgical skin preparation (Betadine) as compared to treatment with the CO2 laser. Standard wounds (5 x 6 cm) were created superficial to the panniculus carnosus on each flank of 37 adult male New Zealand rabbits. Each wound was infected with a standard dose of Pseudomonas aeruginosa. All wounds became grossly infected. On the third day one flank wound was treated with the CO2 laser, the other with the Betadine solution, and a punch biopsy (4 mm) was taken from each wound for quantitative bacterial counts. Less than 10% of the laser-treated wounds grew Pseudomonas, whereas nearly 40% of the iodine-treated wounds remained infected (P less than 0.005). Our early clinical experience using the CO2 laser for the sterilization of infected wounds is also reported.
