The difficulties and surgical decision analysis of laparoscopic technique in treating complicated hepatolithiasis

Abstract

Objective: To explore the difficulties and surgical decision of laparoscopic technique in patients with complicated hepatolithiasis. Methods: The clinical data of 13 patients with complicated hepatolithiasis who underwent laparoscopic hepatectomy at Department of Hepatobiliary Surgery, Affiliated Hospital of North Sichuan Medical College from December 2019 to December 2020 were collected. There were 3 males and 10 females with average age of 50.8 years (range: 14 to 67 years). All patients had upper abdominal pain and a history of cholecystectomy, 4 of them had fever.Seven cases underwent laparoscopic left hemihepatectomy+bile duct exploration, 2 cases underwent laparoscopic right hemihepatectomy+bile duct exploration, 2 cases underwent laparoscopic quadrate hepatectomy (liver 4B+Part 5)+hilar cholangioplasty+bile duct exploration, 2 cases underwent laparoscopic quadrate lobe resection (liver 4B+Part 5)+cholangioplasty+cholangiojejunostomy. All patients were re-examined with abdominal ultrasound and choledochoscope 3 months after operation. Results: The median operation time was 5.2 hours (range: 3.6-6.5 hours), blood loss was 278 ml (range: 120-580 ml). During the operation, 1 case had duodenal bulb injury, and the defect area was about 1.0 cm × 1.2 cm. After timely detection, the defect area was carefully evaluated and trimmed. Absorbable suture was used to suture duodenal bulb, and gastrojejunostomy was performed after repair. One case had small intestinal serosa injury, which was intermittently sutured and embedded with absorbable suture. All the patients recovered smoothly without death. Three months after the operation, 12 patients completed abdominal ultrasound and T-tube sinus choledochoscopy. Residual stones were found in 3 patients, stones were removed in 2 patients by T-tube sinus choledochoscopy 3 months after the operation, 1 patient was still in the recovery period (within 3 months after surgery). No residual stones were found in the remaining 10 patients. Conclusion: The three key laparoscopic techniques in operation of complex hepatolithiasis: adhesiolysis and porta hepatis exposure, laparoscopic hepatectomy, and laparoscopic choledochojejunostomy are very important.
