Combined Thoracoscopic and Laparoscopic Esophagectomy vs. Hand-assisted Transhiatal Esophagectomy: A Prospective Trial.

Esophagectomy for benign or malignant disease of the esophagus can be performed using a transhiatal technique or Ivor Lewis technique (combined laparotomy with thoracotomy). These procedures can be associated with significant morbidity and mortality \[1\]. Advances in minimally invasive technology and surgical techniques have allowed us to explore the possibility of performing esophagectomy using minimally invasive surgical techniques. Minimally invasive esophagectomy represents a new alternative to conventional open esophagectomy. It is a technically demanding operation requiring advanced laparoscopic surgical skills, appropriate instrumentation, and thorough knowledge of open esophagectomy. Multiple authors have reported the use of video-assisted thoracoscopy or laparoscopy to facilitate esophagectomy \[2-6\]. Most of these reports have utilized a standard laparotomy in combination with thoracoscopy to perform esophageal mobilization or laparoscopy with a mini-laparotomy to perform esophagectomy. DePaula was the first to report a large series of 48 patients undergoing laparoscopic transhiatal esophagectomy for benign (n=24) and malignant disease (n=24) \[7\]. In 2 patients, conversion to open surgery was required and 2 others required thoracoscopic assistance. Postoperative complications were low in the benign group but higher in the carcinoma group. The 30-day mortality rate was 16% in patients with carcinoma undergoing laparoscopic transhiatal esophagectomy. DePaula concluded that the patients who benefit most from this procedure are those with benign disease. Swanstrom recently reported nine cases of laparoscopic total esophagectomy \[8\]. There were no conversions to laparotomy. One patient required a right thoracoscopy with intrathoracic anastomosis due to poor viability of the gastric tube. The mean operative time was 6.5 hours with a mean hospital stay of 6.4 days. However, the advantages of minimally invasive esophagectomy have not been observed. The aim of this prospective trial is to evaluate the physiologic outcome, clinical outcome, and quality of life after combined thoracoscopic and laparoscopic esophagectomy vs. transhiatal esophagectomy.

Sex

All

Minimum age

18 Years

Inclusion Criteria:

1. Patients with biopsy proven esophageal malignancies
2. Patients with recalcitrant severe esophageal stricture
3. Karnofsky score \>60
4. No previous treatment for any other cancer over the past 2 years (except for skin cancer)

Exclusion Criteria:

1. Malignant tracheoesophageal fistula or presence of tracheal involvement
2. Unacceptable operative risk
3. Tumor size greater than 12 centimeters.
4. Tumor involvement of the aorta or trachea.
5. Renal or liver insufficiency (Creatinine \> 2.0, transaminase \> fourfold)
6. WBCs \<2,000, platelets \<80,000
7. Presence of metastatic disease
8. Patients with previous esophageal resection
9. Minors and pregnant women are excluded. The chance of esophageal cancer presenting in anyone under 18 years of age is essentially null. Pregnant women are excluded because of safety for the fetus.
