Minimally Invasive Esophagectomy Pain Control Trial

July 17, 2025 updated by: Swedish Medical Center

A Randomized Controlled Trial Comparing Local Intercostal Nerve Blocks, Cryo-ablation Plus Intercostal Nerve Blocks, and Serratus Plane Catheter Plus Intercostal Nerve Blocks After Minimally Invasive Esophagectomy

A pilot randomized controlled trial comparing intercostal nerve blocks, cryo-ablation plus intercostal nerve blocks, and serratus plane catheter plus intercostal nerve blocks in patients undergoing esophagectomies with minimally invasive thoracic approaches.

Study Overview

Detailed Description

Pilot study planned to consent 30 patients in total with a projected study timeline of 2-3 years for completion. Participants will be enrolled in the study and randomized in their preoperative clinic visit. On the day of surgery, they will receive the intervention they were randomized to. 10 patients will be randomized to the intercostal block group, 10 patients will be randomized to the cryo-ablation plus intercostal block group, and 10 patients will be randomized to the serratus plane catheter plus intercostal block group. They will be followed throughout their hospital stay until discharge for data collection purposes. Once the patient is discharged from the hospital, post-operative follow-up in the Swedish Thoracic Surgery Clinic will be collected up to 1 year post-operatively.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: local intercostal nerve block
Patients receiving intercostal blocks will receive a total of 1.0 cc/kg of 0.25% Bupivacaine + epinephrine. This will be divided into two-thirds allocated for use in the chest/intercostal block and one-third allocated for use in the abdomen.
Patients receiving intercostal blocks will receive a total of 1.0 cc/kg of 0.25% Bupivacaine + epinephrine. This will be divided into two-thirds allocated for use in the chest/intercostal block and one-third allocated for use in the abdomen.

The pain service and thoracic surgery attending physician will assess if the patient's pain is not well-controlled using the pain modality they are randomized to. If additional pain control is needed, this will likely consist of a thoracic epidural catheter.

Any additional pain control will be added as an adjunct to the study arm and will be noted in the data set.

Active Comparator: cryo-ablation plus intercostal nerve block
Patients receiving cryo-analgesia and intercostal blocks, the patient will receive cryo-ablation prior to the intercostal block. The cryo-ablation will occur 2 cm from the sympathetic chain 2 intercostal spaces above and 2 intercostal spaces below the access incision. The patient will also receive a total of 1.0 cc/kg of 0.25% Bupivacaine + epinephrine. This will be divided into two-thirds allocated for use in the chest/intercostal block and one-third allocated for use in the abdomen.
The cryo-ablation will occur 2 cm from the sympathetic chain 2 intercostal spaces above and 2 intercostal spaces below the access incision. The patient will also receive a total of 1.2 cc/kg of 0.25% Bupivacaine + epinephrine. This will be divided into two-thirds allocated for use in the chest/intercostal block and one-third allocated for use in the abdomen.

Active Comparator: serratus plane catheter plus intercostal nerve block
Patients receiving serratus plane catheter blocks and intercostal nerve blocks, a total of 1.0 cc/kg of 0.25% Bupivacaine + epinephrine will be administered. A total of 20 cc of the weight-based calculation will be reserved for the serratus plane catheter. The remaining local anesthetic will be divided into two-thirds for the chest and one-third for the abdomen. Patients with serratus plane catheters will have an ongoing infusion of 0.2% ropivacaine at 8 ml per hour. The serratus plane catheters will also receive a bolus of 20 ml of 0.25% bupivacaine with epinephrine on Post Operative Day (POD) #1, 2, 3, 4, and 5 by the pain service.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Post Operative Pain Change Over Time
Time Frame: Baseline (prior to OR) to every 12 hours postoperatively thru Post Operative Day 4.
Compare post-operative pain score changes over time between intercostal nerve blocks, cryo-analgesia, and serratus plane catheters in patients undergoing minimally invasive esophagectomy. Patients will be asked specifically about thoracic/chest pain and asked to rate this pain on a Likert pain scale of 0-10, 0 being no pain and 10 being the worst pain they can imagine.
