Understanding Gastrojejunostomy – A Surgical Bypass for Gastric Obstruction

Simplifying the Gastrojejunostomy Concept

Gastrojejunostomy is a surgical procedure that connects the stomach to the jejunum, a part of the small intestine. It is done to bypass a blocked or damaged part of the stomach or duodenum. This surgery helps improve digestion when the normal route is obstructed.

Bypassing Barriers – How Gastrojejunostomy is performed

Gastrojejunostomy is usually performed through open or laparoscopic surgery. A new connection (anastomosis) is made between the stomach and the jejunum, allowing food to pass directly into the mid-small intestine. This helps bypass tumors, ulcers, or other obstructions in the stomach or duodenum. Laparoscopic methods use trocars, graspers, electrosurgical units, and endoscopic staplers. Surgical sutures or staplers secure the new opening to prevent leaks. This procedure relieves symptoms like vomiting, nausea, and severe pain caused by gastric outlet obstruction.

When is Gastrojejunostomy Necessary?

• Gastric outlet obstruction due to stomach or duodenal cancer
• Chronic peptic ulcers causing narrowing of the duodenum
• Benign gastric strictures or scarring
• Palliative care for unresectable gastrointestinal malignancies

Key Devices in the Procedure

1. Nasogastric Tube (NG Tube)
2. Feeding Jejunostomy Tube (FJT)
3. Endoscopic Ultrasound (EUS) System
4. Guidewire (Hydrophilic or Nitinol)
5. Endoscopic Needle Knife / Cystotome
6. Balloon Dilator
7. Lumen-Apposing Metal Stent (LAMS)
8. Hemoclip / Endoscopic Clip
9. Endoscopic Irrigation Pump
10. CO₂ Insufflator with Tubing Set

Pre-Surgical Patient Evaluation

Patients undergoing gastrojejunostomy require careful evaluation before surgery. Imaging tests like CT scan or endoscopy help confirm the obstruction site. Nutritional status is reviewed, as many patients are malnourished and may need support. Comorbid conditions such as diabetes or heart disease are assessed and managed. Basic blood tests and performance scores guide the surgical approach. This ensures safe and individualized treatment planning.
