The effect of enhanced recovery after minimally invasive esophagectomy: a randomized controlled trial

Essential updates 2022/2023: Recent advances in perioperative management of esophagectomy to improve operative outcomes

In the era of minimally invasive surgery, esophagectomy remains a highly invasive procedure with a high rate of postoperative complications. Preoperative risk assessment is essential for planning esophagectomy in patients with esophageal cancer, and it is crucial to implement evidence-based perioperative management to mitigate these risks. Perioperative support from multidisciplinary teams has recently been reported to improve the perioperative nutritional status and long-term survival of patients undergoing esophagectomy. Intraoperative management of anesthesia and fluid therapy also significantly affects short-term outcomes after esophagectomy. In this narrative review, we outline the recent updates in the perioperative management of esophagectomy, focusing on preoperative risk assessment, intraoperative management, and perioperative support by multidisciplinary teams to improve operative outcomes.

Clinical implementation of minimally invasive esophagectomy

BACKGROUND

Minimally invasive surgery is becoming the method of choice for the resection of esophageal cancer worldwide.

METHODS

Retrospective analysis of prospectively collected clinical data in a tertiary care center with a detailed description of the course of the program.

RESULTS

A total of 136 transthoracic esophageal resections were performed between 2010 and 2023. The study group included 116 operations, 69 of which were fully minimally invasive and 47 hybrid. 80.0% of the study group underwent surgery using a multimodality approach. The median operation time was 431 min (± 103). The R0 resection rate was 100%. Forty-two patients (36.2%) had no postoperative complications. The postoperative Clavien-Dindo > IIIb morbidity was 27%. The postoperative 90-d mortality rate was 1.7%. The average number of lymph nodes removed in the last quarter of cancer patients was 31. The anastomotic insufficiency rate for reoperation was 4% (Ivor-Lewis 4.2%, McKeown 5%).

CONCLUSIONS

With extensive expertise in high-end minimally invasive abdominal and thoracic surgery, implementation of a minimally invasive esophageal resection program with a clinical and oncologic outcome within generally accepted limits is feasible.

Enhanced Recovery Protocol Versus Conventional Care in Patients Undergoing Esophagectomy for Cancer: Advantages in Clinical and Patient-Reported Outcomes

BACKGROUND

This study was designed to compare the clinical and patient-reported outcomes (PROs) between the enhanced recovery after surgery (ERAS) protocol and conventional care in patients undergoing esophagectomy for cancer, which have not previously been compared.

METHODS

This single-center retrospective study included prospective PRO data from August 2019 to June 2021. Clinical outcomes included perioperative complications and postoperative length of stay (PLOS). Patient-reported outcomes were assessed by using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 (QLQ-C30) and esophagus-specific module (QLQ-OES18) preoperatively to 6 months postoperatively. Mixed-effects models were used to longitudinally compare quality of life (QOL) scores between the two modes.

RESULTS

Patients undergoing conventional care and ERAS were analyzed (n = 348 and 109, respectively). The ERAS group had fewer overall complications, pneumonia, arrhythmia, and a shorter PLOS than the conventional group, and outperformed the conventional group in five functional QLQ-C30 domains and five symptom QLQ-OES18 domains, including less dysphagia (p < 0.0001), trouble talking (p = 0.0006), and better eating (p < 0.0001). These advantages persisted for 3 months postoperatively. For the cervical circular stapled anastomosis, the initial domains and duration of benefit were reduced in the ERAS group.

CONCLUSIONS

The ERAS protocol has significant advantages over conventional care in terms of clinical outcomes, lowering postoperative symptom burden, and improving functional QOL in patients who have undergone esophagectomy. Selection of the optimal technique for cervical anastomosis is a key operative component of ERAS that maintains the symptom domains and duration of the advantages of PROs.

The Evolution of Enhanced Recovery After Surgery: Assessing the Clinical Benefits of Developments Within Enhanced Recovery After Surgery Protocols in Adult Cervical Deformity Surgery

STUDY DESIGN

Retrospective cohort.

OBJECTIVE

To investigate the impact of evolving Enhanced Recovery After Surgery (ERAS) protocols on outcomes after cervical deformity (CD) surgery.

BACKGROUND

ERAS can help accelerate patient recovery and assist hospitals in maximizing the incentives of bundled payment models while maintaining high-quality patient care. However, there remains a paucity of literature assessing how developments have impacted outcomes after adult CD surgery.

METHODS

Patients with operative CD 18 years or older with pre-baseline and 2 years (2Y) postoperative data, who underwent ERAS protocols, were stratified by increasing implantation of ERAS components: (1) early (multimodal pain program), (2) intermediate (early protocol + paraspinal blocks, early ambulation), and (3) late (early/intermediate protocols + comprehensive prehabilitation). Differences in demographics, clinical outcomes, radiographic alignment targets, perioperative factors, and complication rates were assessed through Bonferroni-adjusted means comparison analysis.

RESULTS

A total of 131 patients were included (59.4 ± 11.7 y, 45% females, 28.8 ± 6.0 kg/m 2 ). Of these patients, 38.9% were considered "early," 36.6% were "intermediate," and 24.4% were "late." Perioperatively, rates of intraoperative complications were lower in the late group ( P = 0.036). Postoperatively, discharge disposition differed significantly between cohorts, with late patients more likely to be discharged to home versus early or intermediate cohorts [χ 2 (2) = 37.973, P < 0.001]. In terms of postoperative disability recovery, intermediate and late patients demonstrated incrementally improved 6 W modified Japanese Orthopedic Association scores ( P = 0.004), and late patients maintained significantly higher mean Euro-QOL 5-Dimension Questionnaire and modified Japanese Orthopedic Association scores by 1 year ( P < 0.001, P = 0.026). By 2Y, cohorts demonstrated incrementally increasing SWAL-QOL scores (all domains P < 0.028) domain scores versus early or intermediate cohorts. By 2Y, incrementally decreasing reoperation was observed in early versus intermediate versus late cohorts ( P = 0.034).

CONCLUSIONS

The present study demonstrates that patients enrolled in an evolving ERAS program demonstrate incremental improvement in preoperative optimization and candidate selection, greater likelihood of discharge to home, decreased postoperative disability and dysphasia burden, and decreased likelihood of intraoperative complications and reoperation rates.

An esophagectomy surgical Apgar score-based nomogram-a risk-based postoperative triage system: a phase II randomised trial

Background

The esophagectomy surgical Apgar score (eSAS) has been found to be a predictor of postoperative complications in esophagectomy. In our previous study, we built a graphic nomogram based on eSAS and demonstrated that it can effectively predict the risk of major morbidity after esophagectomy. In this study, we aimed to assess the benefits of using an eSAS-based nomogram model as a postoperative risk-based triage system for patients undergoing esophagectomy.

Methods

We enrolled 119 patients diagnosed with esophageal carcinoma and randomly assigned them to a nomogram group (NG) or control group (CG) from January 2019 to December 2020. Patients in the NG were assigned to a low-risk group and high-risk group based on the nomogram. Patients in the high-risk group were admitted to the intensive care unit (ICU) after esophagectomy. Risk estimation in the CG patients was based on the surgeon's clinical experience. Thirty-day major complications, postoperative hospital stay, hospital costs, and quality of life (QOL) during the follow-up were compared between the two groups.

Results

Baseline clinicopathological characteristics were comparable between the NG (n=58) and CG (n=61). All patients underwent esophagectomy. Postoperative complications were significantly higher in the CG (30, 49.2%) than in the NG (14, 24.1%) (P=0.008), with pneumonia being the most common (CG: 23, 37.7%; NG: 12, 20.7%; P=0.042). There was no significant difference in anastomotic leakage (NG: 1, 1.7%; CG: 6, 9.8%; P=0.12). Postoperative median hospital stay was shorter in the NG (14 days) than in the CG (16 days) (P=0.041). Hospital costs (NG: ¥60,045.1; CG: ¥63,961.5; P=0.21) and postoperative QOL did not differ significantly between groups.

Conclusions

An eSAS-based nomogram as a triage system can reduce the overall occurrence of postoperative complications and shorten postoperative hospital stay without increasing hospital costs.

Association of clonal haematopoiesis with severe postoperative complications in patients undergoing radical oesophagectomy

BACKGROUND

Clonal haematopoiesis (CH) is an age-associated clonal expansion of blood cells driven by leukaemia-associated somatic mutations. Although CH has been reported to be a risk factor for leukaemia and a number of non-haematopoietic diseases, its role in perioperative medicine remains unexplored.

METHODS

This was a single-centre, prospective, observational study. Patients undergoing radical oesophagectomy were enrolled, and peripheral blood samples were collected for DNA sequencing. Patients with haematopoietic somatic mutations (variant allele frequencies ≥1%) in the DNMT3A gene, TET2 gene, or both were defined as CH carriers. The primary outcome was the incidence of severe postoperative complications (Clavien-Dindo classification ≥3). The secondary outcomes included the major types of postoperative complications, mortality, and other common perioperative variables.

RESULTS

Clonal haematopoiesis was found in 21.2% (33/156) of the patients (mean age: 66 yr [range: 26-79 yr]; 83% males). Some 14/33 (42.4%) patients with CH had severe postoperative complications, compared with patients without CH carriers (28/123 [22.8%]; P=0.024). Multivariable logistic regression analysis showed that CH was associated with an increased risk of developing severe postoperative complications (odds ratio, 3.63; 95% confidence interval, 1.37-9.66; P=0.010). Among the major postoperative complications, the incidence of pulmonary complications was significantly higher in the patients with CH than in those without CH (15 in 33 [45.5%] vs 30 in 123 [24.4%], P=0.018).

CONCLUSIONS

Clonal haematopoiesis was associated with a higher incidence of severe postoperative complications in patients undergoing radical oesophagectomy, suggesting that clonal haematopoiesis can play an important role in perioperative medicine.
