Objective:
To assess potentially modifiable perioperative risk factors for anastomotic leakage in adult patients undergoing colorectal surgery.
Summary Background Data:
Colorectal anastomotic leakage (CAL) is the single most important denominator of postoperative outcome after colorectal surgery. To lower the risk of CAL, the current research focused on the association of potentially modifiable risk factors, both surgical and anesthesiological.
Methods:
A consecutive series of adult patients undergoing colorectal surgery with primary anastomosis was enrolled from January 2016 to December 2018. Fourteen hospitals in Europe and Australia prospectively collected perioperative data by carrying out the LekCheck, a short checklist carried out in the operating theater as a time-out procedure just prior to the creation of the anastomosis to check perioperative values on 1) general condition 2) local perfusion and oxygenation, 3) contamination, and 4) surgery related factors. Univariate and multivariate logistic regression analysis were performed to identify perioperative potentially modifiable risk factors for CAL.
Results:
There were 1562 patients included in this study. CAL was reported in 132 (8.5%) patients. Low preoperative hemoglobin (OR 5.40,
P
< 0.001), contamination of the operative field (OR 2.98,
P
< 0.001), hyperglycemia (OR 2.80,
P
= 0.003), duration of surgery of more than 3 hours (OR 1.86,
P
= 0.010), administration of vasopressors (OR 1.80,
P
= 0.010), inadequate timing of preoperative antibiotic prophylaxis (OR 1.62,
P
= 0.047), and application of epidural analgesia (OR, 1.81,
P
= 0. 014) were all associated with CAL.
Conclusions:
This study identified 7 perioperative potentially modifiable risk factors for CAL. The results enable the development of a multimodal and multidisciplinary strategy to create an optimal perioperative condition to finally lower CAL rates.
Background and Objectives: Surgery for colorectal cancer (CRC) negatively affects health-related quality of life (HRQoL). Addressing shortcomings in literature, the purpose of this study was to evaluate the impact of surgery for CRC on the course of HRQoL from baseline up to 2 years after diagnosis.Methods: In this prospective, population-based study patients with newly diagnosed CRC were included between 2016 and 2019. HRQoL was assessed by the EORTC QLQ-C30 questionnaire over time both between and within subgroups of patients that underwent right-sided colonic, left-sided colonic, and rectal resection using linear mixed model analyses.
Results:The study included 415 patients of whom 148 patients underwent right-sided colonic (36%), 147 left-sided colonic (35%), and 120 rectal resection (29%). Overall, HRQoL scores restored to baseline level 1 year after diagnosis.Impact of surgery seems to be more prominent in patients who underwent rectal resection, as they experienced more pain and had worse role and social functioning scores 4 weeks after surgery. Finally, among patients who underwent left-sided and rectal resection, physical functioning did not return to baseline level during follow-up.
Conclusion:This study shows several differences (between-group and within-group) in HRQoL according to surgery type and offers perspective which patients may need additional support in the care pathway.
Background: Controversial evidence currently exists regarding the feasibility and effectiveness to improve preoperative aerobic fitness during home-based prehabilitation in patients scheduled for liver or pancreatic resection, whereas morbidity rates are high following these resections. The primary aim of this study is to evaluate the preoperative oxygen uptake (VO 2 ) at the ventilatory anaerobic threshold before and after a four-week home-based preoperative training program with nutritional supplementation in high-risk patients scheduled for elective liver or pancreatic resection. Secondary aims are to evaluate program feasibility, immune system function, cardiopulmonary exercise test responses, individual progression profiles on training responses, quality of life, and postoperative course. Methods: In this multicenter study with a pretest-posttest design, patients with a liver or pancreatic tumor scheduled for elective resection will be recruited. To select the high-risk fraction of this surgical population, their VO 2 at the ventilatory anaerobic threshold should be <11 ml/kg/min for final inclusion. A planned total of 24 high-risk patients will participate in a four-week (three sessions per week) home-based bimodal prehabilitation program. The partly supervised home-based preoperative training program consists of individualized goal setting followed by titration of interval and endurance training on an advanced cycle ergometer, combined with functional task exercises. Additionally, patients will be given protein and vitamin/mineral supplementation. Discussion: Effects of a partly supervised home-based bimodal prehabilitation regimen are unknown in high-risk patients opting for liver or pancreatic resection. Improved preoperative aerobic fitness might translate into improved postoperative outcomes and a reduced demand on care resources.
Background
Although it is known that excessive intraoperative fluid and vasopressor agents are detrimental for anastomotic healing, optimal anesthesiology protocols for colorectal surgery are currently lacking.
Objective
To scrutinize the current hemodynamic practice and vasopressor use and their relation to colorectal anastomotic leakage.
Design
A secondary analysis of a previously published prospective observational study: the LekCheck study.
Study setting
Adult patients undergoing a colorectal resection with the creation of a primary anastomosis.
Outcome measures
Colorectal anastomotic leakage (CAL) within 30 days postoperatively, hospital length of stay and 30-day mortality.
Results
Of the 1548 patients, 579 (37%) received vasopressor agents during surgery. Of these, 201 were treated with solely noradrenaline, 349 were treated with phenylephrine, and 29 received ephedrine. CAL rate significantly differed between the patients receiving vasopressor agents during surgery compared to patients without (11.8% vs 6.3%, p < 0.001). CAL was significantly higher in the group receiving phenylephrine compared to noradrenaline (14.3% vs 6%, p < 0.001). Vasopressor agents were used more often in patients treated with Goal Directed Therapy (47% vs 34.6%, p < 0.001). There was a higher mortality rate in patients with vasopressors compared to the group without (2.8% vs 0.4%, p = 0.01, OR 3.8). Mortality was higher in the noradrenaline group compared to the phenylephrine and those without vasopressors (5% vs. 0.4% and 1.7%, respectively, p < 0.001). In multivariable analysis, patients with intraoperative vasopressor agents had an increased risk to develop CAL (OR 2.1, CI 1.3–3.2, p = 0.001).
Conclusion
The present study contributes to the evidence that intraoperative use of vasopressor agents is associated with a higher rate of CAL. This study helps to create awareness on the (necessity to) use of vasopressor agents in colorectal surgery patients in striving for successful anastomotic wound healing. Future research will be required to balance vasopressor agent dosage in view of colorectal anastomotic leakage.
