Both treatment approaches were equally effective but the intraoperative ERCP group had less morbidity, a shorter hospital stay, and reduced costs. The lower morbidity in the intraoperative ERCP group resulted from the lower rate of papillotomy and lower rates of post-ERCP pancreatitis and cholecystitis. Total morbidity was principally related to the type of treatment approach used.
We think that conservative treatment should not be prolonged beyond 14 days and that endoscopic treatment should be performed at that stage. Endoscopic sealing treatment achieves a very high success rate, without complications and at a lower cost. It could probably reduce the hospital stay, and avoid some unnecessary surgical interventions. Appropriate multicenter randomized trials are needed to confirm these results.
The usefulness and clinical applicability of quantitative plasma polymorphonuclear elastase determinations in the diagnosis of the severity of acute pancreatitis was analysed in a multicentre study and was compared with the usual prognostic systems of Ranson and Osborne et al. The study comprised 182 patients, 154 with a mild episode of acute pancreatitis and 28 with a severe episode, defined by the development of major complications or a fatal outcome. In the severe cases neutrophilic elastase reached significantly higher values than in mild cases (P less than 0.001) by the time the patient was admitted (2-12 h after the onset of the disease), reflecting considerable leucocyte activation. The sensitivity and specificity of this test are therefore greater than 90 per cent, with a positive severity predictive value of almost 80 per cent at the time of admission and 97 per cent after 24 h, and a negative predictive value of approximately 98 per cent. In addition to requiring 48 h for evaluation, the usual prognostic systems show a sensitivity of 77-85 per cent, a specificity of 70-77 per cent, a positive predictive value of 40-48 per cent, and a negative predictive value of 92-95 per cent, clearly lower than those obtained with leucocyte elastase. Polymorphonuclear elastase is therefore a very early and reliable marker in the diagnosis of the severity of acute pancreatitis, in addition to being easily adaptable to the routine of any hospital laboratory.
Background:The methods for preventing post-polypectomy bleeding (PPB) are not standardised and there are groups that use hemoclips for this purpose. Objective: To study whether the use of hemoclips reduces PPB complications. Materials and Methods: Prospective, randomised study of patients with pedunculated polyps larger than 10 mm. The patients were included in two groups (hemoclip before polypectomy -HC-and standard polypectomy -SP-). This study has been registered with the trial registration number NCT01565993. Results: 105 polypectomies were performed (98 patients), 66 (62.9%) in the HC group. The total rate of complications was 10,6% in the HC group (4.5% early bleeding, 1.5% severe delayed bleeding, 4,5% mucosal burns, 1.5% perforation). In the SP group, the rate of total complications was 7,7%, (7,7% early bleeding, no significant differences). In view of the unexpected increase in the morbidity of the hemoclip group, the study was suspended without reaching the sample size. In an ad hoc analysis, which includes the standard polypectomy patients who refused to participate in the study (35 polyps), the total morbidity was 5,7% (no perforations and 2 patients with premature bleeding).When we compared the morbidity of the HC group to the morbidity of SP group plus R group (74 polyps), we also failed to detect any significant differences in terms of PPB, but did in terms of perforation. Conclusion:The prophylactic use of hemoclips in polypectomies of large pedunculated polyps leads to a further risk of mucosal burns and perforation that is not acceptable, and does not reduce the risk of PPB.
The major papilla of Vater is usually located in the second portion of the duodenum, to the posterior medial wall. Sometimes the mouth of the biliary duct is located in other areas. Drainage of the common bile duct into the pylorus is extremely rare. A 73-year old man, with a history of duodenal ulcer, was admitted to hospital with the diagnosis of cholangitis. Dilatation of the extrahepatic biliary duct was observed by abdominal ultrasonography, and endoscopic retrograde cholangiopancreatography (ERCP) was performed. No area suggesting the presence of the papilla of Vater was found within the second duodenal portion. Finally the major papilla was located in the theoretical pyloric duct. Cholangiography was performed and choledocholithiasis was found in the biliary tree. The patient underwent dilatation of the papilla with a balloon tyre and removal of a 7 mm stone using a Dormia basket, which solved the problem without further complications. This anomaly increased the difficulty of performing therapeutic interventions during ERCP. This alteration in anatomy may increase the risk of complications during papillotomy, with a theoretically higher risk of perforation. Dilatation using a balloon was the chosen therapeutic technique both in our case and in the literature, due to its low rate of complications.
The best modality for foreign body removal has been the subject of much controversy over the years. We have read with great interest the recent article by Souza Aguiar Municipal Hospital, Rio de Janeiro, Brazil, describing their experience with the management of esophageal foreign bodies in children. Non-endoscopic methods of removing foreign bodies (such as a Foley catheter guided or not by fluoroscopy) have been successfully used at this center. These methods could be an attractive option because of the following advantages: Shorter hospitalization time; easy to perform; no need for anesthesia; avoids esophagoscopy; and lower costs. However, the complications of these procedures can be severe and potentially fatal if not performed correctly, such as bronchoaspiration, perforation, and acute airway obstruction. In addition, it has some disadvantages, such as the inability to directly view the esophagus and the inability to always retrieve foreign bodies. Therefore, in Western countries clinical practice usually recommends endoscopic removal of foreign bodies under direct vision and with airway protection whenever possible.
Twenty-five (92.6%) of ERCP complications occurred during the first 6 h, making the use of this short observation period safe for an early discharge. The evolution of the patients who developed delayed complications was unremarkable. Whenever outpatient ERCP is feasible, it should be done to help cut costs.
In the treatment of patients with symptomatic cholelithiasis and choledocholithiasis (CBDS) detected during intraoperative cholangiography (IOC), or when the preoperative study of a patient at intermediate risk for CBDS cannot be completed due to the lack of imaging techniques required for confirmation, or if they are available and yield contradictory radiological and clinical results, patients can be treated using intraoperative endoscopic retrograde cholangiopancreatography (ERCP) during the laparoscopic treatment or postoperative ERCP if the IOC finds CBDS. The choice of treatment depends on the level of experience and availability of each option at each hospital. Intraoperative ERCP has the advantage of being a single-stage treatment and has a significant success rate, an easy learning curve, low morbidity involving a shorter hospital stay and lower costs than the two-stage treatments (postoperative and preoperative ERCP). Intraoperative ERCP is also a good salvage treatment when preoperative ERCP fails or when total laparoscopic management also fails.
