The Capio Prostate Cancer Center Model for Prostate Cancer Diagnostics-Real-world Evidence from 2018 to 2022.

Background: The Capio Prostate Cancer Center (Capio PCC) in Stockholm, Sweden, adopts a comprehensive diagnostic approach, utilizing prostate-specific antigen (PSA), Stockholm3, and magnetic resonance imaging (MRI) for prostate cancer risk assessment, followed by targeted and systematic biopsies for high-risk cases. Objective: This study aims to elucidate the clinical process and real-world outcomes of the Capio PCC model for prostate cancer diagnosis at Capio S:t Göran Hospital. Design setting and participants: Between 2018 and 2022, a cohort of 12 406 men aged 45-75 yr underwent prostate cancer testing, adhering to Capio PCC's structured diagnostic protocol. Outcome measurements and statistical analysis: We provide a comprehensive description of the Capio PCC model and present results from its implementation, including assessments of PSA, Stockholm3, MRI scans, and biopsies. A comparative analysis is conducted between the diagnostic outcomes obtained at Capio PCC and those obtained at other regions in Sweden. Results and limitations: The median participant age was 61 yr (interquartile range [IQR]: 55-67), with PSA levels at 1.6 ng/ml (IQR: 0.8-3.3) and Stockholm3 scores at 4 (IQR: 3-11). Among 1064 men (8.6%) undergoing biopsies, 611 (57% of biopsied) were diagnosed with International Society of Urological Pathology grade ≥ 2 cancer. Notably, employing a Stockholm3 ≥ 15 cutoff for biopsy, in lieu of PSA ≥ 3 ng/ml, reduced biopsy recommendations by 43%. For men with PSA levels between 1.5 and 2.9 ng/ml, 360 (12%) exhibited Stockholm3 scores of ≥ 15, with 72 (56% of biopsied) diagnosed with clinically significant prostate cancer. A comparative analysis with national Swedish prostate cancer detection data indicated that the Capio PCC model (vs Sweden) revealed a distribution of 14% (vs 25%) low-risk, 59% (vs 42%) intermediate-risk, and 26% (vs 30%) high-risk and advanced cancers. Conclusions: This study underscores the effectiveness of the protocol-driven diagnostic process at Capio PCC, enabling earlier detection of intermediate-risk prostate cancer and reducing the need for MRI assessments compared with standard prostate cancer care in Sweden. Patient summary: At the Capio Prostate Cancer Center, a novel diagnostic approach incorporating prostate-specific antigen, Stockholm3, magnetic resonance imaging, and targeted biopsies has been implemented to enhance prostate cancer testing and diagnosis in Stockholm, Sweden.

The Prostate Cancer Center at Capio S:t Göran hospital is located in Stockholm and offers testing for prostate cancer. The pathway applies task shifting from doctors to nurses and new and innovative test methods, and leverages digitalization opportunities to enable a cost-efficient pathway with high specificity and sensitivity. In this article, we describe our experiences of the Capio S:t Göran Model.

Introduction of Small Stitch Small Bite technique: a retrospective long-term follow-up.

PURPOSE: Standardization of abdominal wall closure is suggested to improve quality and reduce the risk for late abdominal wall complications. The purpose of this study was to explore the impact of a structured introduction of guidelines for abdominal wall closure on the rates of incisional hernia and wound dehiscence. METHODS: All procedures performed via a midline incision in 2010-2011 and 2016-2017 at Capio St Göran's Hospital were identified and assessed for complications and risk factors. RESULTS: Six hundred two procedures were registered in 2010-2011, and 518 in 2016-2017. Four years after the implementation of new guidelines, 93% of procedures were performed using the standardized technique. There was no significant difference in the incidence of incisional hernia or wound dehiscence between the groups. In multivariate Cox proportional hazard analysis, BMI > 25, wound dehiscence, and postoperative wound infection were found to be independent risk factors for incisional hernia (all p < 0.05). In multivariate logistic regression analysis, male gender and chronic obstructive pulmonary disease were risk factors for wound dehiscence (both p < 0.05). CONCLUSIONS: The present study failed to show a significant improvement in rates of incisional hernia and wound dehiscence after the introduction of Small Stitch Small Bites. When introducing a new standardized technique for closing the abdomen, education and structural implementation of guidelines may have an impact in the long run. The risk factors identified should be taken into consideration when closing a midline incision to identify patients with high risk.

Incidence of wound dehiscence after colorectal cancer surgery: results from a national population-based register for colorectal cancer.

BACKGROUND: Patient-related risk factors for wound dehiscence after colorectal surgery remain obscure. METHODS: All open abdominal procedures for colorectal cancer registered in the Swedish Colorectal Cancer Registry (SCRCR, 5) 2007-2013 were identified. Potential risk factors for wound dehiscence were identified by cross-matching between the SCRCR and the National Patient Register (NPR). The endpoint in this study was reoperation for wound dehiscence registered in either the SCRCR or NPR and patients not reoperated were considered controls. RESULTS: A total of 30,050 patients were included in the study. In a multivariable regression analysis, age > 70 years, male gender, BMI > 30, history of chronic obstructive pulmonary disease, history of generalised inflammatory disease, and duration of surgery less than 180 min were independently and significantly associated with increased risk for wound dehiscence. A history of diabetes, chronic renal disease, liver cirrhosis, and distant metastases was not associated with wound dehiscence. The hazard ratio for postoperative death was 1.24 for patients who underwent reoperation for wound dehiscence compared with that for controls. DISCUSSION: Patients reoperated for wound dehiscence face a significantly higher postoperative mortality than those without. Risk factors include male gender, age > 70 years, obesity, history of chronic obstructive pulmonary disease, and history of generalised inflammatory disease. Patients at high risk for developing wound dehiscence may, if identified preoperatively, benefit from active prevention measures implemented in routine surgical practice.

Incisional hernia after surgery for colorectal cancer: a population-based register study.

BACKGROUND: Our knowledge on the incidence of incisional hernia and risk factors for developing incisional hernia following surgery for colorectal cancer is far from complete. METHODS: All procedures registered in the Swedish Colorectal Cancer Register (SCRCR) 2007-2013 were identified. Patients with comorbid disease diagnoses, registered at admissions and visits prior to the procedure and relevant to this study, were obtained from the National Patient Register (NPR). These diagnoses included cardiovascular disease, connective tissue disorders, liver cirrhosis, renal failure, diabetes, chronic obstructive lung disease and chronic inflammatory conditions. Data on occurrence of incisional hernias were obtained by combining data from the SCRCR and the NPR (International Classification of Diseases code). RESULTS: During 2007-2013, 39,984 procedures were registered in the SCRCR. After excluding laparoscopic procedures, procedures repeated on the same patient, procedures with concomitant liver resection and procedures without laparotomy, 28,913 cases remained for analysis. Five years after surgery, the cumulative incidence of incisional hernia was 5.3%. In multivariate proportional hazard analysis, significantly increased risk for incisional hernia was found for the male gender (hazard ratio [HR] 1.40, 95% confidence interval [CI] 1.21-1.62), operation time exceeding 180 min (HR 1.25, CI 1.08-1.45), body mass index (BMI) > 30 (HR 1.78, CI 1.51-2.09), age < 70 years (HR 1.34, CI 1.16-1.56) and postoperative wound complication (HR 2.09, CI 1.70-2.58). DISCUSSION: Men, patients younger than 70 years and patients with BMI > 30 face a higher risk for incisional hernia. The risk is also increased in cases where the procedure takes longer than 3 h or where postoperative wound complications occur. These patients will benefit from measures aimed at preventing the development of incisional hernia.

Prophylactic Resorbable Synthetic Mesh to Prevent Wound Dehiscence and Incisional Hernia in High High-risk Laparotomy: A Pilot Study of Using TIGR Matrix Mesh.

BACKGROUND: Wound dehiscence and incisional hernia are potentially serious complications following abdominal surgery, especially if performed through a midline incision. Although prophylactic reinforcement with on-lay mesh has been shown to reduce this risk, a permanent mesh carries the risk of seroma formation, infection, and persistent pain. The aim of this study was to assess the safety of a reabsorbable on-lay mesh to reinforce the midline suture in patients with high risk for wound dehiscence or incisional hernia. METHOD: Sixteen patients with three or more risk factors for wound dehiscence or incisional hernia were included. A TIGR(®) Matrix mesh, composed of a mixture of 40% copolymer fibers of polyglycolide, polylactide, and polytrimethylene carbonate and 60% copolymer fibers of polylactide and polytrimethylene carbonate, was placed on the aponeurosis with an overlap of five on either side and fixated with continuous monofilament polydioxanone suture. All postoperative complications were registered at clinical follow-up. RESULTS: Mean follow-up was 9 months. One patient developed a seroma that needed drainage and antibiotic treatment. One patient had a wound infection that needed antibiotic treatment. There was no complication requiring a reoperation. No wound dehiscence or incisional hernia was seen. CONCLUSION: On-lay placement of TIGR(®) Matrix is safe and may provide a feasible way of reinforcing the suture line in patients with high risk for postoperative wound dehiscence or incisional hernia. Larger samples are required, however, if one is to draw any conclusion regarding the safety and effectiveness of this technique.
