European consensus on essential steps of Minimally Invasive Ivor Lewis and McKeown Esophagectomy through Delphi methodology.

ABSTRACT:

Background

Minimally invasive esophagectomy (MIE) is a complex and technically demanding procedure with a long learning curve, which is associated with increased morbidity and mortality. To master MIE, training in essential steps is crucial. Yet, no consensus on essential steps of MIE is available. The aim of this study was to achieve expert consensus on essential steps in Ivor Lewis and McKeown MIE through Delphi methodology.

Methods

Based on expert opinion and peer-reviewed literature, essential steps were defined for Ivor Lewis (IL) and McKeown (McK) MIE. In a round table discussion, experts finalized the lists of steps and an online Delphi questionnaire was sent to an international expert panel (7 European countries) of minimally invasive upper GI surgeons. Based on replies and comments, steps were adjusted and rephrased and sent in iterative fashion until consensus was achieved.

Results

Two Delphi rounds were conducted and response rates were 74% (23 out of 31 experts) for the first and 81% (27 out of 33 experts) for the second round. Consensus was achieved on 106 essential steps for both the IL and McK approach. Cronbach's alpha in the first round was 0.78 (IL) and 0.78 (McK) and in the second round 0.92 (IL) and 0.88 (McK).

Conclusions

Consensus among European experts was achieved on essential surgical steps for both Ivor Lewis and McKeown minimally invasive esophagectomy.

Project description:Minimally invasive esophagectomy (MIE) has consistently been associated with improved perioperative outcome and similar oncological safety compared to open esophagectomy. However, it is currently unclear what type of MIE is preferred for patients with resectable esophageal cancer.Literature was searched in Medline, Embase and the Cochrane library combining relevant search terms. Articles that included patients undergoing totally minimally invasive esophagectomy (TMIE) or hybrid minimally invasive esophagectomy (HMIE) and compared McKeown with Ivor Lewis procedures were included. Studies were excluded if they included >10% of patients undergoing a procedure other than MIE McKeown or MIE Ivor Lewis (i.e., transhiatal resections). The primary outcome parameter was anastomotic leakage. Secondary outcome parameters were: other complications, reinterventions, reoperations, hospital length of stay, ICU length of stay, postoperative mortality, operative time, blood loss, R0 resection rate, lymph nodes examined, quality of life and costs.Five studies with a total of 1,681 patients undergoing TMIE were included. There were no studies comparing HMIE McKeown versus HMIE Ivor Lewis. There were no randomized controlled trials and all included studies were cohort studies with a moderate risk of bias. No meta-analysis could be performed for R0 resection rate, survival, quality of life and costs because there was insufficient data available for these parameters. The incidence of anastomotic leakage did not differ between the groups [relative risk (RR) =1.39, 95% confidence interval (CI) =0.90-10.38, P=0.14]. TMIE Ivor Lewis was associated with a lower incidence of recurrent laryngeal nerve (RLN) trauma (RR =6.70, 95% CI =3.09-14.55, P<0.001), a shorter hospital length of stay [standardized mean difference (SMD) =0.17, 95% CI =0.06-0.28, P=0.002] and less blood loss (SMD =0.69, 95% CI =0.25-1.12, P=0.002).TMIE Ivor Lewis is associated with improved outcome regarding RLN trauma, hospital length of stay and blood loss as compared to TMIE-McKeown, but the incidence of anastomotic leakage is not different. The evidence is limited, of low quality and at risk for bias. A randomized controlled trial is currently being performed in order to demonstrate whether a McKeown or Ivor Lewis procedure should be preferred in patients undergoing MIE.
