Defining a textbook outcome for the resection of colorectal liver metastases.

INTRODUCTION: Textbook outcomes (TBO) are composite measures of care which may be superior in assessing quality compared to traditional methods. We aim to define TBO which are specific to surgical resection of colorectal liver metastases, and investigate their impact on survival. METHODS: Single center analysis of all liver resections performed at our center from 2009 to 2020. A Cox model was used to identify perioperative outcomes which impacted on overall survival. These were retained with important postoperative outcomes to form a "TBO." The impact of a TBO on overall survival was investigated using Kaplan-Meier curve analysis. RESULTS: TBO was achieved in 72.2% (197/273) of resections. Major morbidity (Clavien-Dindo ≥3) at 19.4% was the major limiting factor in not achieving a TBO. TBO was associated with improved 3-year (77% vs. 55%), 5-year (60.7% vs. 42.5%), and median (93 vs. 44 months) overall survival (log-rank test, p = 0.006). Multivariable analysis revealed age >65 years, American Society of Anaesthesiologists Grade III-IV, and resection of >2 segments as factors predictive of not achieving a TBO. CONCLUSION: TBO is a useful composite measure in surgery for colorectal liver metastases. It can highlight areas which may be targeted for quality improvement and be useful as a tool to examine variation between centers. Achieving a TBO is associated with a significant improvement in survival.

Significance of Distal Runoff Score as a Key Influencer on Clinical Outcomes after Endovascular Interventions for Superficial Femoral Artery Disease.

BACKGROUND: Endovascular therapy (EVT) is being adopted by many surgeons as a suitable first choice in the treatment of most femoropopliteal disease when clinically indicated. However, there are multiple factors affecting the outcome of EVT including the anatomy of lesions and distal runoff status. The evidence of runoff effect on the outcome of superficial femoral artery (SFA) interventions is still scarce and not well studied in the current literature. The aim of this study was to investigate the effect of runoff score on the outcomes of SFA endovascular interventions. METHODS: Retrospective analysis was carried out on prospectively collected data on patients who underwent SFA endovascular intervention for critical limb ischemia (CLI) in a single tertiary center. Patients with Rutherford categories 4, 5, and 6 who did not have any previous vascular interventions were included in the study. The modified SVS runoff score was used after calculating scores from popliteal and all tibial vessels. Runoff was stratified into good (score <5), compromised (score 5-10), and poor (score >10). Amputation-free survival, patency rates, and overall survival were compared between all groups at 5 years. RESULTS: Between 2011 and 2018, 254 procedures were performed in 220 patients. Technical success was >92%; 66 patients required SFA stents, and 55 had concomitant tibial angioplasty. There was no significant difference between good, compromised, or poor runoff groups regarding complication rates, with 3.5% overall perioperative mortality (5 cases in the compromised group and 4 in the poor runoff group). A runoff score of <5 was associated with significantly marked clinical improvement (P < 0.001). Patency rates were significantly worse in the compromised and poor runoff groups, with 5-year cumulative primary patency rates of 80%, 50%, and 22% in the good, compromised, and poor runoff groups, respectively (P < 0.001). Amputation-free survival worsened as the runoff got poorer with 98%, 91%, and 78% in the good, compromised, and poor runoff groups, respectively, at 5 years (P < 0.001). SFA stenting and concomitant tibial angioplasty led to slight improvement in patency rates in the poor runoff group. CONCLUSIONS: Poor runoff with a score of >10 was associated with significantly reduced amputation-free survival and patency rates at 5 years in patients undergoing SFA endovascular intervention for CLI. Patients with a runoff score of <5 showed marked clinical improvement postoperatively when compared with patients with a runoff score of ≥5.

Short-term outcomes in older patients with peritoneal malignancy treated with cytoreductive surgery and HIPEC: Experience with 245 patients from a national centre.

BACKGROUND: Cytoreductive Surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) is increasingly accepted as the optimal management of selected patients with peritoneal malignancy. There is limited published evidence on outcomes in older patients treated by this complex therapeutic strategy. METHODS: A retrospective review of a prospective database of all patients who underwent CRS with HIPEC in a single institution over seven years. A comparative analysis of outcomes in patients under 65 undergoing CRS and HIPEC with patients ≥65 years was performed. The key endpoints were morbidity, mortality, reintervention rate and length of stay in the high dependency/intensive care (HDU/ICU) units. RESULTS: Overall, 245 patients underwent CRS and HIPEC during the study period, with 76/245 (31%) ≥65 years at the time of intervention. Tumour burden measured by the peritoneal carcinomatosis index (PCI) score was a median of 11 for both groups. Median length of hospital stay in the ≥65-year-old group was 14.5 days versus 13 days in the <65-year-old group (∗p = 0.01). Patients aged ≥65-years spent a median of one more day in the critical care unit ∗(p = 0.001). Significant morbidity (Clavien-Dindo ≥ Grade IIIa) was higher in the ≥65-year than the <65-year group (18.4% versus 11.2%). There were no perioperative deaths in the ≥65-year group. CONCLUSION: This study demonstrates higher perioperative major morbidity in ≥65-year group, but with low mortality in patients undergoing CRS/HIPEC for disseminated intraperitoneal malignancy. This increased morbidity does not translate into higher rates of re-interventions and highlights the importance of optimal patient selection.
