Purpose:  The goal of this study was to evaluate the experience of 11 years of wire-guided forceps biopsy via PTCD in patients with obstructive jaundice., Materials and Methods:  In a retrospective approach, 56 biopsies in 51 patients were analyzed (22 female, 29 male). Data was collected from 2006 to 2016. Mean age was 71 years (range: 34 - 86 years). Data was extracted from dig. Patients' records (KIS, PACS, RIS) to be analyzed in Microsoft Excel., Results:  All 56 procedures were technically successful. Stenosis in anastomoses were benign due to scarring in 7 patients and in 9 due to papillitis or others. In 4 patients, results in anastomosis were malignant. In 19 patients without anastomosis, CCC was the diagnosis, thereof 10 klatskin, 9 stenosis in other locations, followed by gastric, pancreatic, and colon carcinoma in 5, 3, and 2 patients. Three patients had a CUP (multimetering in case of more than 1 related category). Overall results were 35 mal. and 16 benign, 76.8 % of all proc. had a correct histopathologic result, and 23.2 % were false negative. Sensitivity was 65.8 %, which results in negative predictive value of 58.1 %. There was no false positive and so specificity was 100 %, as was the positive predictive value. False negative results (no malignancy but clinically and imaging suspect) were corrected by rerunning the procedure, by CT-guided biopsy or by 1 PET-CT. In 1 case the surg. sample brought the result. Minor complications occurred in 8 patients: shivering in 1 case, distinct but hemodynamically not relevant hemobilia in 5 cases, 2 portovenal bleedings. All bleedings were short-term and self-limiting., Conclusion:  Despite good feasibility, low peri- and post-interv. risk and high validity the forceps biopsy via PTCD is not widely used. For experienced interventionalists, it is an effective method for obtaining histology., Competing Interests: Disclosure The authors report no conflicts of interest in this work., (© Georg Thieme Verlag KG Stuttgart · New York.)

Objectives: Recurrent oesophageal carcinoma complicated by the development of a tracheo-oesophageal fistula is a crushing condition. In this situation, endoscopic double stenting may provide a quick and safe option for palliation., Methods: The outcomes of patients who received endoscopic parallel stent implantation for tracheo-oesophageal fistula due to recurrent oesophageal cancer at a German tertiary referral hospital between 2006 and 2013 were reviewed in a retrospective case study., Results: A total of 9 patients were identified (mean age 59.9 years). Tumour entity was squamous cell carcinoma, adenocarcinoma and neuroendocrine cancer of the oesophagus in 5, 3 and 1 case, respectively. The mean interval between primary treatment and recurrence was 19.2 months. Successful double-stent placement was always feasible. Complete closure of the communication between oesophagus and respiratory system was accomplished in all cases by stent implantation. There were no stent-associated complications. The mean survival following stent insertion was 64 days (6-121 days). After successful double stenting, 5 patients were fit enough to receive palliative chemo- or radiotherapy. Seven patients were finally discharged home after adequate oral intake had been achieved. Fatal aspiration pneumonia with respiratory failure occurred in 2 cases., Conclusions: Endoscopic parallel stent implantation provides an easy and ubiquitous available technique for closure and palliation of tracheo-oesophageal fistula caused by recurrent oesophageal cancer. Immediate sealing of the fistula and relief of symptoms related to aspiration is achieved while hazardous operations are avoided. Therefore, we recommend endoscopic parallel stent insertion as the treatment of choice in case of tracheo-oesophageal fistula caused by recurrent oesophageal cancer.

Objectives: Tracheobronchial fistulas are rare but life-threatening complications after oesophagectomy. Leakage of the oesophagointestinal anastomosis with inflammatory involvement of the tracheobronchial tree is the predominant reason for postoperative fistulization between the airways and the oesophagus or the gastric tube. Successful management is challenging and still controversially discussed. After promising results in the treatment of intrathoracic anastomotic leaks, we adopted endoscopic stent implantation as the primary treatment option in patients with anastomotic leak-induced tracheobronchial fistula. The aim of this study was to investigate the feasibility, the limits and the results of this procedure., Methods: Between January 2004 and December 2010, 222 consecutive patients underwent oesophageal resection mainly for oesophageal cancer. An anastomotic leak-induced tracheobronchial fistula was bronchoscopically verified in seven patients. Four patients received endoscopic implantation of either a self-expanding tracheal or oesophageal stent or both as primary treatment. Surgical re-exploration was mandatory in 2 patients because of necrosis of the pulled-up gastric tube or gangrene of the airways. One patient was conservatively managed., Results: Endoscopic stent placement was successfully accomplished in all 4 patients. Two patients received an oesophageal stent, one patient a tracheal stent and one patient both an oesophageal and a tracheal stent. Closure of the fistula was achieved in all cases and 3 patients finally recovered while one died by reason of respiratory failure. In both surgical re-explored patients resection of the gastric tube was performed, and in one patient, because of subtotal gangrene of the right bronchial tree, emergency pneumectomy was also mandatory. Both patients died due to severe sepsis and respiratory failure. The one conservatively treated patient died from severe pneumonia., Conclusions: Treatment of anastomotic leak-induced tracheobronchial fistulas by means of oesophageal and tracheal stent implantation is feasible. If stent insertion is limited by gastric tube necrosis or bronchial gangrene, the prognosis is likely to be fatal.

Background: Management of endoscopic retrograde cholangiopancreatography (ERCP)-associated duodenal perforation remains controversial. Some recommend surgery, while others recommend conservative treatment., Methods: A retrospective chart review was conducted to identify patients treated at our institution for ERCP-related duodenal perforations. Study variables included indication for ERCP, clinical presentation, diagnostic procedures, time to diagnosis and treatment, location of injury, management, length of stay in hospital and survival., Results: Between January 2000 and October 2009, 12 232 ERCP procedures were performed at our centre, and perforation occured in 11 patients (0.08%; 5 men, 6 women, mean age 71 yr). Six of the perforations were discovered during ERCP; 5 required radiologic imaging for diagnosis. Three perforations were diagnosed incidentally by follow-up ERCP. In 1 patient, perforation occurred 3 years after the procedure owing to a dislocated stent. Four of 11 perforations were stent-related; in 2 patients ERCP was performed in a nonanatomic situation (Billroth II gastroenterostomy). Free peritoneal perforation occurred in 4 patients; 1 was successfully managed conservatively. Four patients (36%) were treated surgically and none died. Five patients were managed conservatively with a successful outcome, and 2 patients died after conservative treatment (18%). Operative treatment included hepaticojejunostomy and duodenostomy (1 patient), suture of the perforation with T-drain (1 patient) and suture only (2 patients). The mean length of stay in hospital for all patients was 20 days., Conclusion: Post-ERCP duodenal perforations are associated with significant morbidity and mortality. Immediate surgical evaluation and close monitoring is needed. Management should be individually tailored based on clinical findings only.

Background: Intrathoracic anastomotic leakage after esophagectomy is associated with high morbidity and mortality. Because of disappointing results after surgical reexploration endoscopic stent implantation was introduced as primary treatment option with improved outcome. Aortoesophageal fistula is a very rare complication and has thus far only anecdotally been reported after esophagectomy. The aim of this retrospective study was to investigate if endoscopic stent implantation increases the incidence of postoperative aortoesophageal fistula by reason of stent-related erosion of the thoracic aorta., Methods: Between January 2004 and October 2010, 213 patients underwent esophageal resection mainly for esophageal cancer. An intrathoracic esophageal anastomotic leak was endoscopically verified in 25 patients. Seventeen patients received endoscopic implantation of a self-expanding stent as primary treatment. In 8 patients a rethoracotomy was mandatory., Results: After successfully accomplished endoscopic stent placement, complete closure of the anastomotic leak was radiologically proven in all 17 patients. In 13 cases, definitive closure and healing of the leak was achieved and the stent could subsequently be removed. In 1 patient, because of early recurrence of very malignant small cell cancer, the stent remained in situ. Three patients developed an erosion of the thoracic aorta with subsequent massive hemorrhage. The mean time between stent insertion and occurrence of aortoesophageal fistula was 26 days. All 3 patients died of exsanguination with severe hypovolemic shock. Postmortem examination confirmed an aortoesophageal fistula in each case., Conclusions: While endoscopic stent implantation seems to be effective in the control of intrathoracic anastomotic leakage, nevertheless the incidence of aortoesophageal fistula caused by stent-related aortic erosion exceeds the thus far reported numbers. Awareness of this life-threatening complication after stent insertion is therefore mandatory., (Copyright © 2011 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.)

Background: Nasogastric tube-feeding often is necessary in the treatment of chronically ill patients. The disadvantage (irritation of the hypopharynx, dislocation, stigma) can be avoided by the percutaneous endoscopic gastrostomy (PEG). In childhood there is only limited experience with this techniques., Patients and Method: We report about 89 children with PEG. Indications were central dysphagia (67), dystrophy caused by chronic renal failure or congenital heart disease (15), application of special diets (6) and gastric volvulus (1). The endoscopy was done in sedation., Results: The PEG was placed in the stomach (73) or duodenum (16). 14 Complications were observed: inflammation at the insertion site (2), perforation (2, healing under conservative treatment), dislocation of the duodenal part into the stomach or occlusion (6) and distraction of the retention disk (4). There were no procedures-related deaths. The mean duration of the PEG was more than 1 year. The affected persons were very pleased with the efficacy of this treatment., Conclusions: In all patients (including infants) requiring long-term tube-feeding the option of a PEG should be taken into consideration. In our experience the PEG is associated with a low rate of complications and provides a major improvement for children who are dependent on tube feeding.

Based on a prospective trial on 91 patients diagnostic and therapeutic evaluation of ERCP in the early phase of acute pancreatitis was carried out. Detection of biliary stone disease and visualization of tumours of the papilla or main bile duct leads to therapeutic consequences (Papillotomy, exstirpation of the tumour). In addition to that, ERCP yields radiomorphologic informations, which seem to be typical for necrotizing pancreatitis. Showing a correlation to severity and prognosis of necrotizing pancreatitis these informations can be used for planning surgical tactics in the course of the disease.
