West China Hospital Achieves World's First Laparoscopic Surgery for Recurrent Stomach Tumor
Surgeons at Sichuan University's West China Hospital successfully performed the world's first laparoscopic removal of a recurrent gastric GIST — a case previously considered too complex for minimally invasive surgery.
A Surgical First: Laparoscopic Removal of Recurrent Gastric GIST
West China Hospital — one of China's top three hospitals and a flagship institution of Sichuan University — has successfully completed what is believed to be the world's first reported case of laparoscopic surgery to remove a recurrent gastrointestinal stromal tumor (GIST) following a previous open abdominal operation.
The case was led by Dr. Yang Kun, Chief Physician at the hospital's Gastric Cancer Center, and has been formally documented as an international first in the medical literature.
The Patient's History
The patient had undergone open abdominal surgery years earlier to remove a gastric GIST — a type of tumor that grows in the wall of the stomach. During a recent follow-up examination, imaging revealed that the tumor had recurred near the original surgical site, with the new lesion measuring approximately 3 × 3 × 2 cm.
The previous open surgery had left a 20 cm abdominal scar with significant keloid formation — a clear indicator of the extensive internal adhesions that would be waiting inside.
Why This Case Was So Difficult
When a patient has had previous open abdominal surgery, the internal organs often develop dense, widespread adhesions — bands of scar tissue that bind organs together in abnormal ways. In this patient's case, the surgical team anticipated that the:
- Greater omentum (fatty tissue covering the intestines)
- Stomach wall
- Small intestine
- Transverse colon
...would all be fused together by thick scar tissue, completely distorting the normal anatomy.
This kind of adhesion is precisely why recurrent abdominal tumors after open surgery have traditionally been considered unsuitable for laparoscopic (keyhole) approaches. Most surgeons worldwide would default to another open procedure.
The Surgical Approach
The West China Hospital team chose to challenge this convention.
Dr. Yang Kun led the operation, assisted by Dr. Chen Xiaolong (Associate Chief Physician) with Dr. Zhang Weihan (Associate Professor) managing the laparoscopic camera.
Using ultrasonic dissection instruments, the team meticulously separated the adhesions layer by layer — a process described as delicately peeling apart tangled silk threads. The goal was twofold:
- Completely remove the recurrent tumor with clear margins
- Preserve as much healthy stomach wall as possible
The results speak for themselves:
| Surgical Metric | Outcome |
|---|---|
| Tumor removal | Complete resection |
| Surgical margins | Clear — no residual tumor on frozen pathology |
| Intraoperative blood loss | Minimal |
| Organ damage | None |
| Time to walking | Day 1 post-surgery |
| Time to eating | Day 1 post-surgery |
| Hospital discharge | Within days |
| Post-operative pain | Mild |
Open Surgery vs. Laparoscopic: What the Patient Gained
| Factor | Open Surgery (Traditional) | Laparoscopic (This Case) |
|---|---|---|
| Incision | 15-20 cm abdominal cut | 3-4 small ports (5-12mm each) |
| Recovery time | 2-4 weeks | Days |
| Post-operative pain | Significant | Mild |
| Infection risk | Higher | Lower |
| Scarring | Large scar (patient already had 20cm scar) | Minimal |
| Hospital stay | 7-14 days | 3-5 days |
Why This Matters for International Patients
Gastrointestinal stromal tumors affect approximately 10-15 per million people worldwide. While many GISTs can be surgically removed, recurrence rates range from 40-90% depending on tumor characteristics — meaning a significant number of patients face the prospect of repeat surgery.
Until now, those repeat operations almost always meant another major open procedure with all its associated risks and long recovery times. This case from West China Hospital demonstrates that even the most adhesion-heavy, anatomically distorted abdomens can be safely approached laparoscopically — if the surgical team has sufficient expertise.

Frequently Asked Questions
What is a GIST and why do they recur after surgery?
Gastrointestinal stromal tumors (GISTs) are tumors that arise from specialized cells in the wall of the digestive tract, most commonly the stomach. Despite successful initial surgery, GISTs can recur locally or at distant sites because microscopic cancer cells may remain or the tumor has a high mitotic rate. Targeted therapy with imatinib reduces recurrence risk but does not eliminate it entirely.
Why is laparoscopic surgery for recurrent GISTs considered so difficult?
Recurrent GISTs are surrounded by scar tissue from the previous surgery, distorting normal anatomy and making it extremely difficult to identify and protect vital structures. Most surgeons default to open surgery for recurrences due to these challenges. West China Hospital's achievement of performing this laparoscopically demonstrates exceptional surgical skill and represents a meaningful advance in minimally invasive oncologic surgery.
What are the benefits of having GIST surgery at West China Hospital?
West China Hospital is one of China's top 3 hospitals with among the highest volumes of gastrointestinal cancer surgery in the world. Their experience with both primary and recurrent GISTs means patients receive treatment from surgeons who have handled hundreds of similar cases. The cost is typically 70-80% less than equivalent surgery in the US, and their pioneering laparoscopic approach means faster recovery and shorter hospital stays.
How much does GIST surgery cost at West China Hospital compared to the US?
Laparoscopic GIST removal at West China Hospital costs approximately $8,000 to $18,000 including surgery, hospital stay, and pathology, compared to $30,000 to $70,000 in the United States. For recurrent GISTs requiring more complex procedures, costs range from $12,000 to $25,000 in China versus $50,000 to $120,000 in the US.
What follow-up care is needed after GIST removal and can it be done in my home country?
After GIST surgery, regular follow-up including CT scans every 3 to 6 months is essential to monitor for recurrence. Targeted therapy with imatinib may be recommended based on the pathology results and mutation analysis. The initial follow-up and treatment plan are established at West China Hospital, and ongoing monitoring can be seamlessly continued by your local oncologist with detailed handoff documentation.
How long do I need to stay in China for GIST surgery at West China Hospital?
Plan for 2 to 4 weeks in China for GIST surgery. This includes pre-operative evaluation and imaging over 2 to 3 days, the laparoscopic procedure, 5 to 10 days of inpatient recovery, and a follow-up appointment before departure. SinomedTrip arranges accommodation in Chengdu and provides a medical coordinator throughout your stay.
