  • Cytoreductive surgery in pseudomyxoma peritonei-aspects of the learning curve
  • 2013

    • Background: Cytoreductive surgery (CRS) plus perioperative intraperitoneal chemotherapy is a highly invasive treatment of peritoneal metastasis and requires many surgical procedures before mastering. The aim of this study was to estimate how many procedures are needed before stabilization can be seen in surgical outcome (R1 surgery, adverse events and bleeding) in patients with pseudomyxoma peritonei (PMP). Patients and methods: All 128 patients with PMP who were treated with CRS alone or CRS plus perioperative intraperitoneal chemotherapy between 2003 and 2008 at the Uppsala University Hospital, Uppsala, Sweden, were included. The learning curve was calculated using the partial least square (PLS) and cumulative sum control chart (CUSUM) graph. Two groups were formed based on the results of the learning curve. The learning curve plateau was considered the same as the stabilization in the CUSUM graph. Group I consisted of patients included during the learning period (n = 73) and Group 11 of patients treated after the learning period ended (n = 55). Comparisons between the groups were made on surgical outcome, survival and adverse events. Results: Stabilization was seen after 220 +/- 10 procedures. A higher occurrence of R1 surgery was seen in Group H (80%) compared to Group I (48%; P = 0.0002). Overall survival increased at four years after surgery in Group H compared to Group I (80% vs. 63%; P = 0.02). Conclusion: CRS plus perioperative intraperitoneal chemotherapy is a highly demanding procedure that requires more than 200 procedures before optimisation in surgical outcome is seen.

  • Sinus Excision and Primary Closure Versus Laying Open in Pilonidal Disease : A Prospective Randomized Trial
  • 2011
  • Ingår i: Diseases of the Colon & Rectum. - 0012-3706 .- 1530-0358. ; 54:3, s. 300-305
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Surgical excision is the standard treatment for chronic pilonidal disease, but all excisional techniques are associated with tissue loss, risk of wound break down, and chronic healing problems. OBJECTIVE: The aim of the study was to compare sinus excision and primary closure vs a laying open technique in a prospective randomized trial. DESIGN, PATIENTS, AND INTERVENTIONS: Eighty patients were randomly assigned to sinus excision and primary closure (n = 39) or laying open (n = 41). Follow-up was performed 1, 3, and 12 months after surgery. MAIN OUTCOME MEASURE: The main outcome measure was the healing rate after 1 year. RESULTS: The healing rate was significantly higher after excision and closure than after laying open at 1 month (20 of 39 vs 8 of 41; P=.005) and 3 months (36 of 38 vs 28 of 39; P=.013) after surgery. At follow-up 12 months after surgery no difference was seen in healing rate between the treatment arms (33 of 37 vs 37 of 38; P=.198). CONCLUSIONS: This prospective randomized trial shows that sinus excision and primary closure results in faster healing than laying open does, but there is no difference in healing rate after 1 year. The laying open procedure is minimally invasive with small risks for the patient, and it might therefore be considered more frequently as the first choice of treatment (www.clinicaltrials.gov. Unique identifier: NCT00997048).
