Status of Laparoscopic Sleeve Gastrectomy in China: A National Survey.

BACKGROUND

Laparoscopic sleeve gastrectomy (LSG) is a favorable bariatric procedure. This study evaluated the status of LSG in China.

METHODS

During the 4 International Forum of Bariatric and Metabolic Surgery in May 2016, Nanjing China, an on-the-spot questionnaire was filled out by 105 attending surgeons with experience of LSG. The feedback data was collected and analyzed.

RESULTS

For preoperative preparations, surgeons preferred blood glucose control with insulin (61.0%), bowel cleaning (33.3%), and fasting and water deprivation (75.2%). For surgical techniques, surgeons preferred 36/38F bougie (86.7%), greater curvature mobilization with ultrasonic energy device (89.5%), direct transection of short gastric vessels (80%), antrum resection within 2-6 cm to the pylorus (84.8%) with 4.8 mm height stapler (72.4%), and 3.5 mm for corpus (94.3%). Whole stapler-line reinforcement, gastric sleeve fixation, leaking test, and abdominal drainage were preferred by 48.6, 62.9, 39, and 47.6% surgeons. For postoperative managements, surgeons preferred nasogastric tube insertion (33.3%), early liquid diet (69.6%), 4 weeks of liquid diet (55.2%), 2000 ml daily water intake before discharge (79%), 4 weeks of PPI (69.5%), and multi-vitamin supplementation 1 week after operation (77.1%). For postoperative complications, preferences were tachycardia as the onset of leak (81.0%) and oral contrast radiography for leak diagnosis (72.4%). Leak managements include US-guided percutaneous drainage (68.6%), nasogastric tube (87.6%), and parenteral nutrition (61%). For prolonged leak, enteral nutrition (87.6%) and Roux-en-Y bypass (84.8%) as the salvage procedure were preferred. 95.2% preferred endoscopic dilation for stricture.

CONCLUSIONS

LSG is gaining its wide application in China, but standardization of LSG is urgently needed.
