Background : Acute pancreatitis is the third most common gastrointestinal disorder requiring hospitalization in the United States, with annual costs exceeding $2 billions. Severe necrotizing pancreatitis is a life-threatening complication developed in approximately 20% of patients. Its mortality rate range from 15% in patients with sterile necrosis to up 30% in case of infected one associated with multi-organ failure. Less invasive treatment techniques are increasingly being used. These techniques can be performed in a so-called step-up approach. Aim: To present the technique for videoscopic assisted retroperitoneal debridement (Vard technique) with covered metallic stent in necrotizing pancreatitis. Method: A guide wire was inserted through the previous catheter that was removed in the next step. Afterwards, the tract was dilated over the guide wire. Then, a partially covered metallic stent was deployed. A 30 degrees laparoscopic camera was inserted and the necrosis removed with forceps through the expanded stent under direct vision. Finally, the stent was removed and a new catheter left in place. Result : This technique was used in a 31-year-old man with acute pain in the upper abdomen and diagnosed as acute biliary pancreatitis with infected necrosis. He was treated with percutaneous drains at weeks 3, 6 and 8. Due to partial recovery, a left lateral VARD was performed (incomplete by fixed and adherent tissue) at 8th week. As the patient´s inflammatory response was reactivated, a second VARD attempt was performed in three weeks later. Afterwards, patient showed complete clinical and imaging resolution. Conclusions : Videoassisted retroperitoneal necrosectomy using partially covered metallic stent is a feasible technique for necrotizing pancreatitis.
Purpose: The present study aimed to determine whether the percentage of bleeding complications differs between the right and the left approaches in percutaneous biliary drainage (PBD) in adult patients.Materials and Methods: This was a prospective, descriptive, nonrandomized comparative and longitudinal study. We included adult patients over 18 years of age who underwent a PBD. We excluded those with a bilateral PBD for the comparative study. Usually, but not exclusively, we performed the right approach under fluoroscopic guidance and the left one under ultrasound and fluoroscopy.Results: Of 150 cases, 63 were performed using the right approach and 61 with the left; 26 were performed with the bilateral. The right approach faced less dilated biliary ducts and more benign diseases. We experienced 20 bleeding complications (13.33%, confidence intervals of 95% = 8.3-19.8), 7 in the bilateral approach, 10 in the right approach, and 3 in the left one. The difference between the right and the left approaches was statistically significant (Fisher P = 0,04). No procedures were required to obtain hemostasis, and only one patient (0.66%, confidence intervals of 95% = 0.009-3.66) (in the right side) required a red blood cell transfusion. We found no related mortality.Conclusions: Global bleeding complications are more likely to appear in the right approach in which less dilated biliary ducts and more benign diseases probably contributed to a higher number of needle passes, portal and hepatic vein punctures, and, therefore, to an increase in the risk of bleeding complications. The significant bleeding complication rate was low (0.66%).
Background: The risk of bile duct injury (BDI) during cholecystectomy remains a concern, despite efforts proposed for increasing safety. The Critical View of Safety (CVS) has been adopted promoting to reduce its risk. Aim: To perform a survey to assess the awareness of the CVS, estimating the proportion of surgeons that correctly identified its elements and its relationship with BDI. Methods: An anonymous online survey was sent to 2096 surgeons inquiring on their common practices during cholecystectomy and their knowledge of the CVS. Results: A total of 446 surgeons responded the survey (21%). The percentage of surgeons that correctly identified the elements of CVS was 21.8% and 24.8% among surgeons claiming to know the CVS. The percentage of surgeons that reported BDI was higher among those that incorrectly identified the elements of the CVS (p=0.03). In the multivariate analysis, career length was the most significant factor related to BDI (p=0.002). Conclusions: The percentage of surgeons that correctly identified the Critical View of Safety was low, even among those who claimed to know the CVS. The percentage of surgeons that reported BDI was higher among those that incorrectly identified the elements of the CVS.
