Open Right Hemicolectomy Is a Safe and Suitable Procedure for Surgical Training: A Comparative Study With 133 Patients.

BACKGROUND AND AIMS: A right hemicolectomy is a technically demanding procedure and the quality of the operation influences the short- and long-term outcomes. An increasing number of certified centers employ surgeons who are specialized in this procedure. Residency training is obligatory, but trainee surgeons often cannot perform technically demanding procedures because of economical and certification requirements imposed on the center. This study was performed to evaluate the suitability of right hemicolectomy as a training procedure. MATERIAL AND METHODS: Between 2009 and 2013, 133 patients received a right hemicolectomy during cancer treatment. Patient data were analyzed in two cohorts: cohort 1 contained 90 patients who were operated by a resident under supervision, and cohort 2 included 43 patients who were operated by a specialized senior surgeon. Outcome and safety were evaluated by mortality rate, anastomotic leakage, complication rate, and operation time. The resection status and the number of resected lymph nodes were surrogate parameters for oncological quality. Gender, age, American Society of Anesthesiologists classification, body mass index, and general risk factors were compared in both cohorts. RESULTS: There was no significant difference in the rate of anastomotic leakage between the two groups (p = 0.799). Oncological criteria were met in both cohorts and the oncological quality was similar between groups. Furthermore, there were no significant differences in risk factors, operating time, postoperative complications, and mortality between the groups. CONCLUSION: Oncological open right hemicolectomy is a safe and suitable training procedure for residency training under standardized conditions.

[Can Topical Negative Pressure Therapy be Performed as a Cost-Effective General Surgery Procedure in the German DRG System?]. / Führt die Vakuumsaugtherapie tatsächlich zu einer Kosteneffektivität in der Allgemeinchirurgie im G-DRG-System?

INTRODUCTION: Topical negative pressure therapy (TNPT) has been established for surgical wound therapy with different indications. Nevertheless, there is only sparse evidence regarding its therapeutic superiority or cost-effectiveness in the German DRG system (G-DRG). This study was designed to analyse the cost-effectiveness of TNPT in the G-DRG system with a focus on daily treatment costs and reimbursement in a general surgery care setting. PATIENTS/MATERIALS AND METHODS: In this retrospective study, we included 176 patients, who underwent TNPT between 2007 and 2011 for general surgery indications. Analysis of the cost-effectiveness involved 149 patients who underwent a simulation to calculate the reimbursement with or without TNPT by a virtual control group in which the TNP procedure was withdrawn for DRG calculation. This was followed by a calculation of costs for wound dressings and TNPT rent and material costs. Comparison between the "true" and the virtual group enabled calculation of the effective remaining surplus per case. RESULTS: Total reimbursement by included TNPT cases was 2,323 ,70.04 €. Costs for wound dressings and TNPT rent were 102,669.20 €. In 41 cases there was a cost-effectiveness (27.5%) with 607,422.03 € with TNP treatment, while the control group without TNP generated revenues of 442,015.10 €. Costs for wound dressings and TNPT rent were 47,376.68 €. In the final account we could generate a cost-effectiveness of 6759 € in 5 years per 149 patients by TNPT. In 108 cases there was no cost-effectiveness (72.5%). CONCLUSION: TNPT applied in a representative general surgery setting allows for wound therapy without a major financial burden. Based on the costs for wound dressings and TNPT rent, a primarily medically based decision when to use TNPT can be performed in a balanced product cost accounting. This study does not analyse the superiority of TNPT in wound care, so further prospective studies are required which focus on therapeutic superiority and cost-effectiveness.
