The future of esophageal surgery

[Laparoscopic transhiatal esophagectomy: outcomes]

BACKGROUND

The laparoscopic transhiatal esophagectomy for benign or malignant disease is a complex operation associated with a high rate of morbidity and mortality. In the last decade this procedure gained popularity and acceptance for treatment of the esophagus cancer and other benign diseases.

AIM

To perform a retrospective analysis in patients with esophageal cancer that was underwent a laparoscopic transhiatal esophagectomy, demonstrated pre and post operative complications and immediate result.

METHODS

From November 1993 to June 2005, 72 patients underwent laparoscopic transhiatal esophagectomy. Sixty-four with malignant neoplasm of esophagus. The males are predominant, and the mean age was 56.5 years. The abdominal part of the operation was totally laparoscopic and the cervical one was made the conventional way. The stomach was pulled up to the neck by the posterior mediastinum.

RESULTS

The laparoscopic transhiatal esophagectomy was initiated in 64 patients. Four patients were converted to open surgery. The mean operation time was 153 minutes. The incidence of cervical fistula was 14.06%. The mortality rate 5.6%.

CONCLUSION

Laparoscopic transhiatal esophagectomy is a secure option in experience centers. The morbility is low, with a faster return to normal activity. Maybe in fact this procedure may be reminded and ponder in the treatment of esophageal disease.

Laparoscopic transhiatal esophagectomy: outcomes

BACKGROUND

Laparoscopic transhiatal esophagectomy, indicated for benign and malignant esophageal diseases, is a complex operation, often associated with a high rate of morbidity and mortality. During the past decade this technique has became well accepted among specialized surgeons for the treatment of esophageal cancer, avoiding thoracotomy and reducing open access complications. The aim of the present study was to retrospectively analyze patients with esophageal cancer who underwent laparoscopic transhiatal esophagectomy.

METHODS

From November 1993 to August 2006, 78 patients underwent laparoscopic transhiatal esophagectomy. There were 68 cases of esophageal cancer (57 males and 21 females, age range = 28-73 years) with a predominant rate of squamous cell carcinoma (60.2%).

RESULTS

The conversion rate was 6.4%. The mean operative time was 153 min with a 12.8% rate of cervical leak and a postoperative (30-day) mortality rate of 5.1%. The four-year survival rate was 19% as determined within a subgroup of 21 patients whose followup during the period was possible.

CONCLUSIONS

Laparoscopic transhiatal esophagectomy is a safe alternative for experienced professionals. This access can improve mortality, hospital stay, and other outcomes when compared with open methods.

Thoracoscopic mobilization of the esophagus. A 6 year experience

BACKGROUND

Traditionally, esophageal resection has been performed using a thoracotomy to access the intrathoracic esophagus. With the aim to avoid the potential morbidity of the open thoracic approach, mobilization of the esophagus under direct vision recently has been described. We report our experience at attempting thoracoscopic mobilization of the esophagus in 162 patients during a 6-year period.

METHODS

Patients with malignancy or end-stage benign disease of the esophagus considered suitable for a three-stage esophagectomy underwent a thoracoscopy with a view to endoscopic mobilization of the esophagus. Of the 162 patients in whom the procedure was attempted, it was abandoned in 9 patients (6%), and the procedure was converted to open surgery in 11 patients (7%).

RESULTS

In the patients whose esophagus was mobilized, the average blood loss was 165 ml, and the average time for the thoracoscopic segment of the surgery was 104 min. In the 133 patients who underwent a resection for invasive malignancy, a limited mediastinal nodal dissection retrieved an average of 11 nodes, and the median survival was 29 months. The 30-day mortality was 3.3% and the in-hospital mortality 5.3%.

CONCLUSIONS

Thoracoscopic mobilization can be performed safely with satisfactory outcomes in a center performing a large volume of esophageal surgery and possessing advanced endoscopic surgery skills. Further assessment of this technique and comparisons with traditional open procedures are needed to assess this approach further as an appropriate oncologic procedure.
