Short esophagus: how much length can we get?

Area of Science:

• Gastroenterology
• Surgical Innovation
• Esophageal Surgery

Background:

• Laparoscopic antireflux surgery necessitates sufficient intra-abdominal esophagus length.
• A short esophagus can lead to wrap herniation and suboptimal clinical results.
• Esophageal elongation techniques are crucial for successful antireflux procedures.

Purpose of the Study:

• To evaluate the maximum esophageal elongation achievable with transhiatal mediastinal dissection.
• To determine if this technique can obviate the need for Collis gastroplasty.
• To assess the impact on clinical outcomes and esophageal acid exposure.

Main Methods:

• Review of a prospective database (2003-2006) of 106 patients with gastroesophageal reflux disease and suspected short esophagus.
• Patients underwent antireflux surgery with extended transhiatal mediastinal dissection.
• Intraoperative measurements quantified intra-abdominal esophageal length; postoperative assessments included pH manometry, UGI series, and symptom scores.

Main Results:

• Mean esophageal elongation of 2.65 cm, resulting in a mean intra-abdominal esophageal length of 3.15 cm.
• No patients required Collis gastroplasty after extended mediastinal dissection.
• Significant improvement in preoperative symptom scores and normalization of distal esophageal acid exposure postoperatively.

Conclusions:

• Extended transhiatal mediastinal dissection is a safe and effective method for elongating a short esophagus.
• This technique eliminates the need for Collis gastroplasty and enhances outcomes in antireflux surgery.
• Establishing at least 3 cm of intra-abdominal esophagus via this dissection is recommended for antireflux procedures.
