Lesión quirúrgica de vía biliar compleja. Manejo conservador / Complex bile duct injury. Conservative management

RESUMEN La colecistectomía laparoscópica es el tratamiento de elección para la litiasis vesicular sintomática. Aunque la tasa de complicaciones es baja, las lesiones de la vía biliar representan un grave problema. La asociación con una lesión vascular (lesión compleja) genera un impacto adicional, disminuyendo la calidad de vida y la sobrevida a largo plazo. Presentamos el caso de una paciente con lesión compleja por compromiso vascular del pedículo hepático derecho que desarrolló una atrofia del parénquima correspondiente. Ante la ausencia de complicaciones sépticas, el tratamiento no operatorio pudo realizarse en forma exitosa.

ABSTRACT Laparoscopic cholecystectomy is considered the standard of care for symptomatic cholelithiasis. Although the rate of complications is low, bile duct injuries represent a serious problem. The association with vascular injury (complex injury) poses an additional impact by reducing the quality of life and long-term survival. We report the case of a female patient with complex injury due to vascular involvement of the right hepatic pedicle who developed right liver atrophy. Non-operative management was successful due to the absence of septic complications.

Risk factors of hepatic artery injury during percutaneous transhepatic biliary drainage / 中华普通外科杂志

Objective:To investigate the incidence and risk factors of hepatic artery injury during percutaneous transhepatic biliary drainage (PTBD).Methods:From Apr 2002 to Dec 2020, the clinical data of 1 446 patients undergoing PTBD were retrospectively analyzed.Results:Hepatic artery injury occurred in 7 cases, with an incidence of 0.48%. Fluoroscopy guided puncture was used in all cases. In those 7 cases (0.48%) a drainage catheter was failed to put in place after multiple attempts, hepatic artery injury occurred in 1 case; One drainage catheter was inserted in 1 314 cases (90.87%), hepatic artery injury occurred in 5 cases; One hundred and twenty-five cases (8.65%) were implanted with two drainage catheter, and 1 case had hepatic artery injury. Failure to successfully insert the drainage catheter increase the incidence of hepatic artery injury ( OR=0.06,95% CI 0.01-0.71, P=0.026) .There were 1 430 cases (98.89%) with oblique needle tip and 5 cases had hepatic artery injury; There were 16 cases (1.11%) with triangular needle tip and 2 cases had hepatic artery injury. Triangular needle tip increased the incidence of hepatic artery injury( OR=55.57, 95% CI 6.84-451.38, P<0.001). Conclusion:Hepatic artery injury is a rare complication of PTBD.The use of triangular needle and the failure of drainage were the risk factors of hepatic artery injury.

Diagnosis,treatment and etiology of hepatic infarction and abscess after pancreaticoduodenal surgery / 中国实用外科杂志

OBJECTIVE: To explore the causes and treatment of hepatic infarction and abscessafter pancreaticoduodenal surgery.METHODS: The clinical data of 11 cases of hepatic infarction or abscess after pancreaticoduodenal surgery in Peking Union Medical College Hospital between January 2012 and December 2018 were analyzed retrospectively.RESULTS: A total of 11 patients were diagnosed of hepatic infarction or abscess after PD.The overall mortality rate was27.3%(3 of 11 patients).54.5%(6/11)had biliary fistula.Of the 11 patients,7 had proper hepatic artery and right accessory hepatic artery occlusion or stenosis,1 had abdominal trunk root stenosis before operation,and 3 had PV stenosis.Enterococcus and Klebsiella were the organisms most frequently cultured,and fungi were also the common pathogens.Antibiotics and selective percutaneous drainage were the main means of treatment.CONCLUSION: Ischemia of hepatic artery and portal vein after PD is the main cause of liver infarction and liver abscess.Biliary fistula and multiple pathogenic bacteria are often associated with high mortality.
