Clinical application of laparoscopy hepatectomy: a single center's experience / 中华肝胆外科杂志

The clinical data of 97 patients who underwent laparoscopic hepatectomy from July 2007 to November 2014 in the First Affiliated Hospital of Wenzhou Medical University was collected.Of the 97 patients,46 cases were diagnosed with hepatolithiasis,20 with primary liver cancer,26 with benign liver tumor,1 with liver abscess,and 4 with metastatic liver cancer.The surgical approaches included laparoscopic left hepatectomy (n =16),left lateral lobectomy (n =35),right hepatectomy (n =2),right posterior lobectomy (n =1),hepatic wedge resection (n =42),and left lateral lobectomy with segment Ⅶ resection (n =1),and 4 cases underwent multi-visceral resection.88 patients underwent laparoscopic hepatectomy and 9 patients were transferred to open hepatectomy.Postoperative complications included bile leakage (n =9),abdominal cavity infection (n =7),ascites (n =1),wound infection (n =1),pleural effusion (n =3) and pulmonary infection (n =1).There was no perioperative death.Taken together,laparoscopic hepatectomy is feasible and efficient for treating liver diseases and it has the advantages of minimal invasion and rapid recovery.

Diagnosis and treatment of Mirizzi syndrome: a single-centre experience / 中华肝胆外科杂志

Objective To study the diagnosis and surgical treatment of Mirizzi syndrome (MS).Method The clinical data of patients with Mirizzi syndrome treated in our center from July 2001 to July 2011 were retrospectively studied and the diagnostic methods,operative strategies and outcomes of surgical treatment were analyzed.Results Mirizzi syndrome (MS) was identified in 56 out of 13800patients who received cholecystectomy (0.4％). MS was diagnosed preoperatively in 30 patients (53.6％).There were 29 patients with Mirizzi syndrome type Ⅰ,17 patients with type Ⅱ,9 patients with type Ⅲ,and 1 patient with type Ⅳ using the Csendes's classification.In two patients (3.6％) coincidental gallbladder carcinoma was detected.An initial laparoscopic approach was attempted in 33patients,and 16 were converted to open surgery.The remaining 23 patients underwent open operation.Surgical procedures included cholecystectomy,choledochotomy and T-tube insertion,simple closure and drainage (via T tube) of the biliary fistula,Roux-en-Y hepaticojejunostomy,radical resection of gallbladder and hepaticojejunostomy.Inadvertent bile duct injury occurred in 2 patients who had an initial laparoscopic approach for a preoperative undiagnosed MS. Postoperative morbidities included biliary leak (n =4) and residual common bile duct stone (n=2).All patients recovered completely and there was no hospital mortality.Conclusions Preoperative diagnosis of Mirizzi syndrome is still challenging despite the availability of multiple imaging modalities.Open surgery remains the standard of care,although laparoscopic treatment may be used in selected patients,especially for type Ⅰ Mirizzi syndrome.Patients with Mirizzi syndrome should be managed differently,basing on intraoperative findings and the type of Mirizzi syndrome.
