Laparoscopic jejunostomy for obstructing upper gastrointestinal malignancies.

Area of Science:

• Surgical Oncology
• Gastroenterology
• Minimally Invasive Surgery

Background:

• Upper gastrointestinal malignancies can cause severe obstruction, complicating nutritional management.
• Endoscopic therapies may not be feasible for all patients with obstructive upper gastrointestinal cancers.
• Neoadjuvant chemotherapy (NAC) is often used for esophageal cancer, requiring adequate nutritional support.

Purpose of the Study:

• To describe a minimally invasive laparoscopic jejunostomy (Lap-J) technique.
• To evaluate the nutritional benefits of Lap-J during NAC in patients with obstructing esophageal cancer.

Main Methods:

• A laparoscopic jejunostomy was performed by exteriorizing a segment of the jejunum and inserting a feeding tube.
• The jejunum was then laparoscopically sutured to the anterior abdominal wall.
• Nutritional parameters (body weight, serum total protein) were compared between patients who received Lap-J prior to NAC and those who received NAC alone.

Main Results:

• Lap-J was successfully performed in 26 cases with a median operative time of 82 minutes.
• The postoperative course was uneventful.
• Lap-J prior to NAC did not result in a decrease in body weight or serum total protein during NAC compared to controls.

Conclusions:

• Minimally invasive laparoscopic jejunostomy is a feasible and safe technique for managing obstructions from upper gastrointestinal malignancies.
• Lap-J provides nutritional support during neoadjuvant chemotherapy without adverse effects on nutritional status.
• This technique is particularly valuable for patients unsuitable for endoscopic intervention.
