Abstract
Background and study aims Two different techniques for percutaneous endoscopic gastrostomy (PEG) have been developed: classical pull-through and direct puncture techniques. This study compared the complication rate for both techniques in a large retrospective patient cohort. Patients and methods Clinical data from patients who received a PEG in four high-volume centers for endoscopy were included retrospectively between January 2016 and December 2018. Patient characteristics and complication rates were correlated in univariate and multivariate analyses. Results Data from 1014 patients undergoing a PEG insertion by the pull-through technique were compared to 183 patients for whom the direct puncture technique was used. The direct puncture technique was associated with a 50 % reduction in minor and 85.7 % reduction in major complications when compared to the pull-through technique. Multivariate analysis of these data revealed an odds ratio of 0.067 (0.02-0.226; P < 0.001) for major complications in the direct puncture group. Conclusions Compared to the pull-through technique, the direct puncture technique resulted in a significant reduction in complications. Despite the retrospective design of this study, these results suggest that the direct puncture technique may be preferable to improve patient safety.

PuraStat in gastrointestinal bleeding: results of a prospective multicentre observational pilot study. Surg Endosc 2021; 36:2954-2961. [PMID: 34129089 PMCID: PMC9001238 DOI: 10.1007/s00464-021-08589-6] [Citation(s) in RCA: 26] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2020] [Accepted: 06/02/2021] [Indexed: 11/28/2022]
Abstract
Background A recently developed haemostatic peptide gel for endoscopic application has been introduced to improve the management of gastrointestinal bleeding. The aim of this pilot study was to evaluate the feasibility, safety, efficacy and indication profiles of PuraStat in a clinical setting. Methods In this prospective observational multicentre pilot study, patients with acute non-variceal gastrointestinal bleeding (upper and lower) were included. Primary and secondary application of PuraStat was evaluated. Haemoglobin, prothrombin time, platelets and transfusion behaviour were documented before and after haemostasis. The efficacy of PuraStat was assessed during the procedure, at 3 days and 1 week after application. Results 111 patients with acute gastrointestinal bleeding were recruited into the study. 70 percent (78/111) of the patients had upper gastrointestinal bleeding and 30% (33/111) had lower gastrointestinal bleeding. After primary application of PuraStat, initial haemostatic success was achieved in 94% of patients (74/79, 95% CI 88–99%), and in 75% of the patients when used as a secondary haemostatic product, following failure of established techniques (24/32, 95% CI 59–91%). The therapeutic success rates (absence of rebleeding) after 3 and 7 days were 91% and 87% after primary use, and 87% and 81% in all study patients. Overall rebleeding rate at 30 day follow-up was 16% (18/111). In the 5 patients who finally required surgery (4.5%), PuraStat allowed temporary haemostasis and stabilisation. Conclusions PuraStat expanded the therapeutic toolbox available for an effective treatment of gastrointestinal bleeding sources. It could be safely applied and administered without complications as a primary or secondary therapy. PuraStat may additionally serve as a bridge to surgery in order to achieve temporary haemostasis in case of refractory severe bleeding, possibly playing a role in preventing immediate emergency surgery.

Abstract
Due to a vulnerable blood supply of the bile ducts, biliary complications are a major source of morbidity after liver transplantation (LT). Manifestation is either seen at the anastomotic region or at multiple locations of the donor biliary system, termed as nonanastomotic biliary strictures. Major risk factors include old donor age, marginal grafts and prolonged ischemia time. Moreover, partial LT or living donor liver transplantation (LDLT) and donation after cardiac death (DCD) bear a markedly higher risk of biliary complications. Especially accumulation of several risk factors is critical and should be avoided. Prophylaxis is still a major issue; however no gold standard is established so far, since many risk factors cannot be influenced directly. The diagnostic workup is mostly started with noninvasive imaging studies namely MRI and MRCP, but direct cholangiography still remains the gold standard. Especially nonanastomotic strictures require a multidisciplinary treatment approach. The primary management of anastomotic strictures is mainly interventional. However, surgical revision is finally indicated in a significant number of cases. Using adequate treatment algorithms, a very high success rate can be achieved in anastomotic complications, but in nonanastomotic strictures a relevant number of graft failures are still inevitable.

Abstract
Abstract
Background
Postpancreatectomy haemorrhage (PPH) is a major cause of morbidity and mortality after pancreaticoduodenectomy (PD). It remains unclear whether performance of a pancreatogastrostomy (PG) instead of a pancreatojejunostomy (PJ) improves outcomes owing to better endoscopic accessibility.
Methods
A large retrospective analysis was undertaken to compare outcomes of PPH, depending on whether a PG or PJ was performed. The primary outcome was the rate of successful endoscopy. A secondary outcome was the therapeutic success after adding surgery.
Results
Of 944 patients who had a PD, 8·4 per cent developed PPH. Endoscopy was the primary intervention in 21 (81 per cent) of 26 patients with a PG and 34 (64 per cent) of 53 with a PJ; it identified the bleeding site in 35 and 25 per cent respectively (P = 0·347). Successful endoscopic treatment was more common in the PG group (31 versus 9 per cent; P = 0·026). Surgery was performed for PPH in 15 patients (58 per cent) with a PG and 35 (66 per cent) with a PJ (P = 0·470). The majority of haemorrhages that required surgery were non-anastomotic intra-abdominal haemorrhages (12 of 15 versus 21 of 35; P = 0·171). Endoscopic or conservative treatment for PPH was successful in 42 per cent of patients with a PG and 32 per cent with a PJ (P = 0·520). The success rate increased to 85 and 91 per cent respectively when surgery was included in the algorithm (P = 0·467).
Conclusion
The type of pancreatic anastomosis and its inherent effect on endoscopic accessibility had very little impact on the outcome of PPH. This was because haemorrhage frequently occurred from intra-abdominal or non-anastomotic intraluminal lesions.

Abstract
We reported the successful administration of infliximab for late-onset OKT3-resistant rejection in two patients, who presented persistent ulcerative inflammation of the ileal graft after intestinal transplantation (ITX). Based on this experience, the present study demonstrated our long-term experience with infliximab for different types of rejection-related and inflammatory allograft alterations. Infliximab administration (5 mg/kg body weight (BW)) was initiated at a mean of 18.2 ± 14.1 months after transplantation. The number of administrations per patient averaged 8.4 ± 6.7. Repeat dosing was timed according to clinical signs and graft histology in addition to serum-levels of tumor necrosis factor alpha (TNFα), lipopolysaccharide binding protein (LBP) and C-reactive protein (CRP). Infliximab was successful in the following patients: patients with late-onset OKT3- and steroid-refractory rejection who presented persistent ulcerative alterations of the ileal graft (n = 5), patients with ulcerative ileitis/anastomositis, who did not show typical histological rejection signs (n = 2), and one patient with early-onset OKT3-resistant rejection. Infliximab was not successful in one patient with early-onset OKT3-resistant rejection that was accompanied by treatment-refractory humoral rejection. In conclusion, infliximab can expand therapeutic options for late-onset OKT3- and steroid-refractory rejection and chronic inflammatory graft alterations in intestinal allograft recipients.

Abstract
Anastomotic leaks after oesophagojejunostomy usually are treated by endoluminal stenting with self-expandable metal or plastic stents. Here we present a patient with more than 4 years of oesophageal stenting for anastomotic leakage after gastrectomy. During the attempted removal of the stent he experienced a perforation of the jejunum. Emergency surgery with complete resection of the stent and transhiatal oesophagojejunostomy was performed. Generally, early removal of oesophageal stents 4-6 weeks after implantation is recommended, as later attempts often fail and may lead to extensive surgery.

Abstract
BACKGROUND/AIMS Radiofrequency ablation (RFA) in the liver is contraindicated in the presence of bilioenteric anastomoses, because it predisposes to occasionally devastating infectious complications. The purpose of this single-center experience is to demonstrate the technical feasibility of such procedures. METHODOLOGY Patients with bilioenteric anastomoses were offered ultrasound-guided RFA, if an interdisciplinary tumor board endorsed this decision, or an intraoperative opportunity to achieve a tumor-free situation emerged. All procedures were carried out under general anesthesia in a surgical operation theatre. RFA was performed percutaneously (n=3) and open surgically (n=3) with two different types of monopolar devices. All patients received antibiotic prophylaxis with various different agents. RESULTS Six patients with seven tumor nodules were treated. The average age of the patients was 59 +/- 7 years. Mean size of the tumors was 20 +/- 7 mm. Median follow up was 15 months. No infectious complication including intrahepatic abscess occurred. No local recurrence was detected. CONCLUSIONS The presented data indicates the feasibility of RFA in patients with bilioenteric anastomoses, and infectious problems, namely intrahepatic abscess formation, do not inevitably occur. The role of antimicrobial prophylaxis remains unclear. The importance of ensuring an unobstructed and uninhibited biliary flow distally in the bilioenteric track is stressed.

Abstract
For patients with irresectable hilar cholangiocarcinoma, liver transplantation (LT) is currently being reassessed because of promising data for neoadjuvant radiochemotherapy. For increased radicality, hepatectomy in combination with pancreatic head resection [extended bile duct resection (EBDR)] was performed for irresectable hilar cholangiocarcinoma during our initial experience. EBDR and LT was performed in 16 patients between 1992 and 1998. No neoadjuvant or adjuvant treatment was performed. The Union Internationale Contre le Cancer stages were I (n = 6), IIA (5), IIB (3), and IV (2). To evaluate the suspected increase in surgical radicality, a matched pair analysis was performed with 8 patients undergoing LT for hilar cholangiocarcinoma without partial pancreatoduodenectomy. The 1-, 5-, and 10-year patient survival rates after EBDR were 63%, 38%, and 38%, respectively. Twelve patients died: 2 died because of postoperative complications, 8 died because of tumor recurrence, and 2 died while recurrence-free more than 10 years after transplantation. Among the 6 stage I patients, only 1 developed tumor recurrence, but 2 died because of postoperative complications. The following factors showed a trend toward inferior survival: distant metastases, positive lymph nodes, high carbohydrate antigen 19-9 levels, and preoperative percutaneous transhepatic cholangiodrainage. When all lymph node-negative patients were considered after the exclusion of perioperative deaths, 10-year survival was 56%. In conclusion, the overall long-term survival was relatively low in our inhomogeneous cohort but favorable in patients without metastases. However, because of the increased perioperative mortality, EBDR is not recommended as a standard procedure for hilar cholangiocarcinoma instead of LT alone. To further improve the results, other approaches such as (neo)adjuvant therapy have to be increasingly investigated.

Abstract
Ischemic-type biliary lesions (ITBL) account for a major part of patients' morbidity and mortality after orthotopic liver transplantation (OLT). The exact origin of this type of biliary complication remains unknown. This study retrospectively evaluated 1843 patients. Patients with primary sclerosing cholangitis were excluded from this study. The diagnosis of ITBL was established only when all other causes of destruction of the biliary tree were ruled out. Donor age (P = 0.028) and cold ischemic time (CIT) (P = 0.002) were found to be significant risk factors for the development of ITBL. Organs that were perfused with University of Wisconsin (UW) solution developed ITBL significantly more often than Histidine-Tryptophan-Ketoglutarate (HTK)-perfused organs (P = 0.036). The same applied to organs harvested externally and shipped to our center versus those that were procured locally by our harvest teams (P < 0.001). Pressure perfusion via the hepatic artery significantly reduced the risk of ITBL (P = 0.001). The only recipient factor that showed a significant influence was Child-Pugh score status C (P = 0.021). Immunologic factors had no significant impact on ITBL. The clinical consequences of this study for our institution have been the strict limitation of CIT to <10 h and the exclusive use of HTK solution. We further advocate that all organ procurement teams perform pressure perfusion on harvested organs.

Abstract
BACKGROUND An elevated body mass index (BMI) is associated with an increased incidence of cancer at the gastro-oesophageal junction. Less is known about the postoperative complication rate and prognosis in relation to the BMI. PATIENTS AND METHODS We investigated 108 patients with cancer of the cardia and a BMI below (group 1, n = 56) or above (group 2, n = 52) 25 kg / m (2), who were operated from 2000 to 2006 in our department. According to the Siewert classification, the tumours were subdivided into 3 types. Patients with type I cancers (n = 26) received a transthoracic oesophageal resection with gastric pull up. Patients with type II (n = 61) or type III (n = 21) cancers underwent an extended gastrectomy. The complication rates and survival were analysed. RESULTS The complications were pulmonary (respiratory insufficiency n = 12, pneumonia n = 12, bronchitis n = 7, pulmonary embolism n = 2), surgical (anastomotic leakage n = 7, abscesses n = 8, bleeding n = 2, chylus fistula n = 1), or functional (dysphagia n = 5, nausea n = 5, heart burn n = 4, delayed enteral passage n = 6, vomiting n = 9). Patients of group 2 showed more delayed enteral passages (5 vs. 1) and more vomiting (7 vs. 2) than those of group 1. The median stay in the intensive care unit was shorter in group 1 than in group 2 (3 vs. 5 days) (p = 0.021). Overall hospitalisation was 14 days in the mean in both groups. We found no significant difference in the postoperative mortality of 6.5 % (n = 7) between the two groups. Overall survival after a follow-up of 42 months was 34 % (group 1) and 25 % (group 2). The difference did not reach statistical significance (p = 0.961). Patients with an elevated BMI show slightly more complications than those with a lower BMI. CONCLUSIONS Our data show that patients with elevated BMI have slightly more complications and an identical long term survival as patients with normal body weight.

Successful endoscopic and surgical management of non-anastomotic biliary strictures after liver transplantation - case report. Ann Transplant 2009; 14:47-51.

Abstract
BACKGROUND One of the most relevant biliary complications after liver transplantation are non-anastomotic strictures which occur in about 10-15%. Untreated they lead to cholestasis, severe graft dysfunction, septic complications, secondary cirrhosis and even death. To date they are usually treated by endoscopic or percutaneous placement of stents and balloon dilatation. A significant amount of patients with non-anastomotic strictures require a liver retransplantation. CASE REPORT A 64 year old patient suffering from HCV induced liver cirrhosis underwent liver transplantation at our hospital. Two months after transplantation due to elevated parameters of cholestasis the patient underwent an endoscopic retrograde cholangiography. Multiple strictures of the bile duct were observed and treated by endoscopic and percutaneous methods until a significant amelioration of the pathological finding in the right liver lobe was achieved. Unfortunately biliary strictures remained in the left liver lobe being resistant to the previous method of treatment. We thus decided to perform a left hemihepatectomy. The postoperative course was unremarkable. CONCLUSIONS The treatment of our patient consisted of over 25 endoscopic and percutaneous interventions and a left hemihepatectomy. The patient was followed up for two years, during which he had no further complaints being in good health. We demonstrated an example of a successful management of one of the most severe late biliary complications after liver transplantation - the non-anastomotic strictures - avoiding a retransplantation of the organ by endoscopic, percutaneous and surgical intervention. Thus a graft resection seems to be possible.

Abstract
BACKGROUND AND AIMS Colonoscopy is an established method of colorectal cancer screening, but has an adenoma miss rate of 10-20%. Detection rates are expected to improve with optimised visualisation methods. This prospective randomised study evaluated narrow-band imaging (NBI), a new technique that may enhance image contrast in colon adenoma detection. METHODS Eligible patients presenting for diagnostic colonoscopy were randomly assigned to undergo wide-angle colonoscopy using either conventional high-resolution imaging or NBI during instrument withdrawal. The primary outcome parameter was the difference in the adenoma detection rate between the two techniques. RESULTS A total of 401 patients were included (mean age 59.4 years, 52.6% men). Adenomas were detected more frequently in the NBI group (23%) than in the control group (17%) with a number of 17 colonoscopies needed to find one additional adenoma patient; however, the difference was not statistically significant (p = 0.129). When the two techniques were compared in consecutive subgroups of 100 study patients, adenoma rates in the NBI group remained fairly stable, whereas these rates steadily increased in the control group (8%, 15%, 17%, and 26.5%, respectively). Significant differences in the first 100 cases (26.5% versus 8%; p = 0.02) could not be maintained in the last 100 cases (25.5% versus 26.5%, p = 0.91). CONCLUSIONS The increased adenoma detection rate means of NBI colonoscopy were statistically not significant. It remains speculative as to whether the increasing adenoma rate in the conventional group may have been caused by a training effect of better polyp recognition on NBI.

Abstract
HISTORY A 53-year-old man with long-standing Crohn's disease presented with recurrent abdominal pain and vomiting; lipase levels were elevated. INVESTIGATIONS AND DIAGNOSIS At admission ultrasound demonstrated a swollen head of the pancreas, dilated pancreatic and intrahepatic bile ducts and peripancreatic fluid. At upper gastrointestinal endoscopy a 10 mm bleeding ulcer was identified, which histologically proved to be epitheloid cell-containing granulomas. A fistula connecting to the hepatocholedochal duct was identified at the floor of the ulcer. Helicobacter pylori was not demonstrated. TREATMENT AND COURSE After sphincterotomy of the papilla of Vater concrements were extracted and a stent was implanted into the common bile duct. Ultimately a total of five stents were consecutively implanted via the major papilla, closing the fistula. After three years all stents were removed and pancreatitis did not recur. CONCLUSION The differential diagnosis of abdominal pain in patients with Crohn's disease is often difficult and should include fistulas of the upper gastrointestinal tract which may be treated endoscopically.

Abstract
Endoscopic therapy is valuable for both acute and chronic pancreatitis. Early endoscopic papillotomy appears, in the case of a severe course of acute biliary pancreatitis, to be advantageous. Endoscopic drainage can be considered in cases of acute fluid retention and necrosis as well as subacute, non-healing pancreatitis or cyst development. By acute chronic pancreatitis with strictures or bile duct stones, papillotomy, dilation and stent insertion can lead to an improvement in pain symptoms. An improvement in endo- or exocrine function, however, is not expected. Studies on the endoscopic therapy of pancreatitis are still very limited, and recommendations can usually only be made based on retrospective case series.

Abstract
BACKGROUND AND OBJECTIVE Intestinal transplantation (ITx) is the only causal therapy of short bowel syndrome (SBS). Long-term survival after ITx has been improved significantly during the last years. The experience with ITx at the Charite, Campus Virchow Klinikum, are described and discussed. PATIENTS AND METHODS Twelve isolated ITx and one multivisceral transplantation (including stomach, pancreatodudenal complex, small intestine, liver, ascending colon, right kidney, and adrenal gland) were performed. Mean recipient age was 37.7+/-10.6 yrs (median: 35 yrs; range: 27 - 58 yrs; M:F = 8:5). All patients had irreversible SBS (0 - 30 cm residual bowel length; mean: 11.8+/-11.4 cm; median: 13 cm). RESULTS 6-months and 1-year patient and graft survival were 85 % (11/13) and 77 % (10/13), respectively. Reasons for graft loss and patient death were necrotizing enterocolitis, severe, muromonab-resistent, acute rejection, and graft ischemia due to complex coagulopathy. All other patients had good long-term outcome. They received enteral nutrition at six hours after operation and were persistently off total parenteral nutrition (TPN) by week two after ITx. CONCLUSION ITx as established in our centre, with 1-year-patient and graft survival rates of 77 %, reflects current international standard. ITx is complementary to conservative and other operative methods of treating SBS. Referral and indication criteria need wider dissemination to prevent life-threatening complications of TPN.

Abstract
Acute rejection resistant to established immunosuppressive rescue protocols remains the most prominent risk factor after intestinal transplantation. In two patients presenting with steroid-resistant severe acute cellular rejection 9 months and 2 years after intestinal transplantation, complete resolution was not achieved despite 5 and 10 days of OKT3 treatment, respectively, and high-dose triple baseline immunosuppression with tacrolimus, rapamycin, and steroids. There was a dissociated course of rejection with persistent moderate to severe rejection in the terminal portion of the graft despite complete recovery from rejection in the proximal parts. Both patients were treated with four subsequent infusions of infliximab (3 mg/kg body weight), a chimeric anti-tumor necrosis factor-alpha antibody. There was an immediate response regarding macroscopic appearance, graft histology, and clinical symptoms. Both patients recovered. In conclusion, infliximab has proven to be an effective rescue therapy in a selected group of patients with steroid and OKT3 refractory severe acute rejection after intestinal transplantation.

Abstract
Ischemic-type biliary lesions (ITBLs) are the most frequent cause of nonanastomotic biliary strictures in liver grafts, affecting about 2-19 % of patients after liver transplantation. ITBL is characterized by bile duct destruction, subsequent stricture formation, and sequestration. We report here the case of a patient affected by extremely severe ITBL, with sequestration and disintegration of the entire bile duct system, in which it was possible to extract the complete biliary tree endoscopically in a single piece. Histological examination revealed that all cells of the bile duct wall had been destroyed within 3 months after liver transplantation and replaced by connective tissue. Subsequently, biliary stricture formation occurred at the hepatic hilum, as well as the adjacent large bile ducts. It may be hypothesized that cellular rejection of small bile ducts leads to the vanishing bile duct syndrome, whereas cellular rejection of large bile ducts results in ITBL. The strictures were repeatedly dilated by endoscopic means, allowing successful control of stricture formation, as well as maintenance of liver function. At the time of writing, the grafted organ and the patient had survived for more than 3 years in good health. This is the first detailed report on a sequestration of the entire bile duct system caused by ITBL, successfully treated for several years by endoscopic means.

Abstract
BACKGROUND Advanced and incurable Klatskin tumors of Bismuth-type III and IV cause obstructive jaundice. Palliation of patients with Klatskin tumors is usually carried out by bilateral endoscopic stent placement. Endoscopic retrograde cholangiography (ERC) in such patients is associated with a comparatively high morbidity and mortality mainly due to postprocedure bacterial cholangitis. To reduce ERC-related complications the outcome of replacing ERC with magnetic resonance cholangiopancreatography (MRCP) was investigated. Subsequently, unilateral contrast injection and stent placement were performed, thus avoiding bilateral contrast injection and stent insertion. METHODS Patients thought to have a Klatskin tumor underwent clinical evaluation, laboratory, and noninvasive imaging studies before ERC. Patients were enrolled in this feasibility study if investigators agreed with the clinical diagnosis of an advanced and incurable Klatskin tumor. MRCP images were used to determine the predominate ductal drainage for the liver segments thus directing stent placement. Based on these findings, unilateral ERC and subsequent unilateral stent placement were performed. Antibiotics were not given before ERC. Amsterdam-type stents (10F) were placed and replaced routinely at 2 months. In cases of earlier occlusion, the stents were replaced immediately. RESULTS Thirty-five patients underwent MRCP, ERC, and unilateral stent deployment. Two further patients enrolled after MRCP were withdrawn because ERC could not be carried out. In 35 patients with unilateral stents bilirubin levels decreased (18.9 +/- 6.3 mg/dL to 3.2 +/- 2.3 mg/dL) and jaundice resolved in 86%. After first stent deployment, post-ERC bacterial cholangitis occurred in 6% (2 of 35) of patients. CONCLUSIONS This new method of MRCP-guided endoscopic unilateral stent placement could reduce ERC-related complications caused by initial stent deployment. The results of this study justify a randomized prospective comparative trial.
