[First combined intestinal and abdominal wall transplantation in the Netherlands]. / Eerste dunnedarm-buikwandtransplantatie in Nederland.

BACKGROUND: When total parenteral nutrition (TPN) is not an option, intestinal transplantation is the sole treatment for patients with end-stage intestinal failure to increase the chance of long-term survival. However, in 20-33% of patients, abdominal wall-related complications occur after isolated intestinal transplantation. CASE DESCRIPTION: The patient is a 24-year-old woman with ultra-short bowel syndrome, caused by a severely complicated history of Crohn's disease. After 5 years of TPN, the patient was referred for intestinal transplantation. In addition, an abdominal wall transplant was required due to an abdominal wall defect, extensive scarring of the abdominal wall and lack of free space within the abdomen. Therefore, a combined intestinal and abdominal wall transplantation was performed. Six months after transplantation the patient has a sufficient abdominal wall, a normal body mass index and no longer requires any feeding lines. CONCLUSION: This case report describes the first combined intestinal and abdominal wall transplantation in the Netherlands and in the Eurotransplant region in a patient with end-stage intestinal failure and loss of abdominal domain.

Abdominal Compartment Syndrome and Intra-abdominal Ischemia in Patients with Severe Acute Pancreatitis.

INTRODUCTION: Severe acute pancreatitis may be complicated by intra-abdominal hypertension (IAH), abdominal compartment syndrome (ACS), and intestinal ischemia. The aim of this retrospective study is to describe the incidence, treatment, and outcome of patients with severe acute pancreatitis and ACS, in particular the occurrence of intestinal ischemia. METHODS: The medical records of all patients admitted with severe acute pancreatitis admitted to the ICU of a tertiary referral center were reviewed. The criteria proposed by the World Society of the Abdominal Compartment Syndrome (WSACS) were used to determine whether patients had IAH or ACS. RESULTS: Fifty-nine patients with severe acute pancreatitis were identified. Intra-abdominal pressure (IAP) measurements were performed in 29 patients (49.2 %). IAH was present in all patients (29/29). ACS developed in 13/29 (44.8 %) patients. Ten patients with ACS underwent decompressive laparotomy. A large proportion of patients with ACS had intra-abdominal ischemia upon laparotomy: 8/13 (61.5 %). Mortality was high in both the ACS group and the IAH group. CONCLUSION: This study confirms that ACS is common in severe acute pancreatitis. Intra-abdominal ischemia occurs in a large proportion of patients with ACS. Swift surgical intervention may be indicated when conservative measures fail in patients with ACS. National and international guidelines need to be updated so that routine IAP measurements become standard of care for patients with severe acute pancreatitis in the ICU.

Impact of appendicitis during pregnancy: no delay in accurate diagnosis and treatment.

BACKGROUND: Acute appendicitis during pregnancy may be associated with serious maternal and/or fetal complications. To date, the optimal clinical approach to the management of pregnant women suspected of having acute appendicitis is subject to debate. The purpose of this retrospective study was to provide recommendations for prospective clinical management of pregnant patients with suspected appendicitis. METHOD: Case records of all pregnant patients suspected of having appendicitis whom underwent appendectomy at our hospital between 1990 and 2010 were reviewed. RESULTS: Appendicitis was histologically verified in fifteen of twenty-one pregnant women, of whom six were diagnosed with perforated appendicitis. Maternal morbidity was seen in two cases. Premature delivery occurred in two out of six cases with perforated appendicitis cases and two out of six cases following a negative appendectomy. Perinatal mortality did not occur. CONCLUSION: Both (perforated) appendicitis and negative appendectomy during pregnancy are associated with a high risk of premature delivery. Clinical presentation and imaging remains vital in deciding whether surgical intervention is indicated. We recommend to cautiously weigh the risks of delay until correct diagnosis with associated increased risk of appendiceal perforation and the risk of unnecessary surgical intervention. Based upon current literature, we recommend clinicians to consider an MRI following an inconclusive or negative abdominal ultrasound aiming to improve diagnostic accuracy to reduce the rate of negative appendectomies. Accurate and prompt diagnosis of acute appendicitis should be strived for to avoid unnecessary exploration and to aim for timely surgical intervention in pregnant women suspected of having appendicitis.

Exchange of best practices within the European Union: surgery standardization of abdominal organ retrieval.

Considering the growing organ demand worldwide, it is crucial to optimize organ retrieval and training of surgeons to reduce the risk of injury during the procedure and increase the quality of organs to be transplanted. In the Netherlands, a national complete trajectory from training of surgeons in procurement surgery to the quality assessment of the procured organs was implemented in 2010. This mandatory trajectory comprises training and certification modules: E-learning, training on the job, and a practical session. Thanks to the ACCORD (Achieving Comprehensive Coordination in Organ Donation) Joint Action coordinated by Spain and co-funded under the European Commission Health Programme, 3 twinning activities (led by France) were set to exchange best practices between countries. The Dutch trajectory is being adapted and implemented in Hungary as one of these twinning activities. The E-learning platform was modified, tested by a panel of Hungarian and UK surgeons, and was awarded in July 2013 by the European Accreditation Council for Continuing Medical Education of the European Union of Medical Specialists. As a pilot phase for future national training, 6 Hungarian surgeons from Semmelweis University are being trained; E-learning platform was fulfilled, and practical sessions, training-on-the-job activities, and evaluations of technical skills are ongoing. The first national practical session was recently organized in Budapest, and the new series of nationwide selected candidates completed the E-learning platform before the practical. There is great potential for sharing best practices and for direct transfer of expertise at the European level, and especially to export this standardized training in organ retrieval to other European countries and even broader. The final goal was to not only provide a national training to all countries lacking such a program but also to improve the quality and safety criteria of organs to be transplanted.

Intraoperative motive for performing a laparoscopic appendectomy on a postoperative histological proven normal appendix.

BACKGROUND: Diagnostic laparoscopy is the ultimate tool to evaluate the appendix. However, the intraoperative evaluation of the appendix is difficult, as the negative appendectomy rate remains 12%-18%. The aim of this study is to analyze the intraoperative motive for performing a laparoscopic appendectomy of an appendix that was proven to be noninflamed after histological examination. METHODS: In 2008 and 2009, in five hospitals, operation reports of all negative laparoscopic appendectomies were retrospectively analyzed in order to assess the intraoperative motive for removing the appendix. RESULTS: A total of 1,465 appendectomies were analyzed with an overall negative appendectomy rate of 9% (132/1,465). In 57% (841/1,465), a laparoscopic appendectomy was performed, with 9% (n = 75) negative appendectomies. In 51% of the negative appendectomies, the visual assessment of the appendix was decisive in performing the appendectomy. In 33%, the surgeon was in doubt whether the appendix was inflamed or normal. In 4%, the surgeon was aware he removed a healthy appendix, and in 9%, an appendectomy was performed for different reasons. CONCLUSION: In more than half of the microscopic healthy appendices, the surgeon was convinced of the diagnosis appendicitis during surgery. Intraoperative laparoscopic assessment of the appendix can be difficult.

An upper gastrointestinal ulcer still bleeding after endoscopy: what comes next?

INTRODUCTION: Recurrent bleeding from an upper gastrointestinal ulcer when endoscopy fails is a reason for radiological or surgical treatment, both of which have their advantages and disadvantages. CASE: Based on a patient with recurrent gastrointestinal bleeding, we reviewed the available evidence regarding the efficacy and safety of surgical treatment and embolisation, respectively. DISCUSSION: Transarterial embolisation (TAE) and surgical treatment are both options for recurrent gastrointestinal bleeding when endoscopy fails. Both therapies have serious complications and a risk of rebleeding. Choosing the therapy depends on the capability of the patient to tolerate haemodynamic instability, resuscitation and hypotension. CONCLUSION: Choosing between TAE and surgery depends a great deal on the case presented, haemodynamic stability and the skills and tools available at that moment.

Documenting correct assessment of biliary anatomy during laparoscopic cholecystectomy.

BACKGROUND: Correct assessment of biliary anatomy can be documented by photographs showing the "critical view of safety" (CVS) but also by intraoperative cholangiography (IOC). METHODS: Photographs of the CVS and IOC images for 63 patients were presented to three expert observers in a random and blinded fashion. The observers answered questions pertaining to whether the biliary anatomy had been conclusively documented. RESULTS: The CVS photographs were judged to be "conclusive" in 27%, "probable" in 35%, and "inconclusive" in 38% of the cases. The IOC images performed better and were judged to be "conclusive" in 57%, "probable" in 25%, and "inconclusive" in 18% of the cases (P < 0.001 compared with the photographs). The observers indicated that they would feel comfortable transecting the cystic duct based on the CVS photographs in 52% of the cases and based on the IOC images in 73% of the cases (P = 0.004). The interobserver agreement was moderate for both methods (kappa values, 0.4-0.5). For patients with a history of cholecystitis, both the CVS photographs and the IOC images were less frequently judged to be sufficient for transection of the cystic duct (P = 0.006 and 0.017, respectively). CONCLUSION: In this series, IOC was superior to photographs of the CVS for documentation of the biliary anatomy during laparoscopic cholecystectomy. However, both methods were judged to be conclusive only for a limited proportion of patients, especially in the case of cholecystitis. This study highlights that documenting assessment of the biliary anatomy is not as straightforward as it seems and that protocols are necessary, especially if the images may be used for medicolegal purposes. Documentation of the biliary anatomy should be addressed during training courses for laparoscopic surgery.

Safety measures during cholecystectomy: results of a nationwide survey.

BACKGROUND: This study aimed to identify safety measures practiced by Dutch surgeons during laparoscopic cholecystectomy. METHOD: An electronic questionnaire was sent to all members of the Dutch Society of Surgery with a registered e-mail address. RESULTS: The response rate was 40.4% and 453 responses were analyzed. The distribution of the respondents with regard to type of hospital was similar to that in the general population of Dutch surgeons. The critical view of safety (CVS) technique is used by 97.6% of the surgeons. It is documented by 92.6%, mostly in the operation report (80.0%), but often augmented by photography (42.7%) or video (30.2%). If the CVS is not obtained, 50.9% of surgeons convert to the open approach, 39.1% continue laparoscopically, and 10.0% perform additional imaging studies. Of Dutch surgeons, 53.2% never perform intraoperative cholangiography (IOC), 41.3% perform it incidentally, and only 2.6% perform it routinely. A total of 105 bile duct injuries (BDIs) were reported in 14,387 cholecystectomies (0.73%). The self-reported major BDI rate (involving the common bile duct) was 0.13%, but these figures need to be confirmed in other studies. CONCLUSION: The CVS approach in laparoscopic cholecystectomy is embraced by virtually all Dutch surgeons. The course of action when CVS is not obtained varies. IOC seems to be an endangered skill as over half the Dutch surgeons never perform it and the rest perform it only incidentally.

A new interventional technique for percutaneous treatment of drainage-resistant liver abscess.

The objective of this case report is to describe a device that can be used as a minimally invasive alternative for the treatment of drainage-resistant liver abscess. The device uses pulse lavage to fragment and evacuate the semi-solid contents of a liver abscess. The treatment of liver abscesses consists of percutaneous drainage, antibiotics and treatment of the underlying cause. This approach can be ineffective if the contents of the abscess cavity are not liquid, and in those cases open surgery is often needed. Here, we describe for the first time a new minimally invasive technique for treating persistent liver abscesses. A patient developed a liver abscess after a hepatico-jejunostomy performed as a palliative treatment for an unresectable pancreatic head carcinoma. Simple drainage by a percutaneously placed pig-tail catheter was insufficient because of inadequate removal of the contents of the abscess cavity. After dilatation of the drain tract the persistent semi-solid necrotic contents were fragmented by a pulsed lavage device, after which the abscess healed uneventfully. The application of pulsed lavage for debridement of drainage-resistant liver abscesses proved to be an effective and minimally invasive alternative to open surgery.

[Occult gastrointestinal bleeding due to a Dieulafoy lesion in the terminal ileum]. / Occult gastro-intestinaal bloedverlies door een laesie van Dieulafoy in het terminale ileum.

A 50-year-old man awaiting liver transplantation for primary sclerosing cholangitis developed iron-deficiency anaemia. Repeated occult gastrointestinal bleeding led to an increasing need for blood transfusions. After multiple oesophagogastroduodenoscopies and colonoscopies, videocapsule endoscopy finally demonstrated a polyp-like lesion in the terminal ileum. The lesion had not been detected despite two attempts (oral and anal) at double-balloon enteroscopy and even a peroperative enteroscopy. Only during a second laparotomy, again involving peroperative enteroscopy, a small red lesion was detected and resected 80 cm proximal to the ileocecal valve (Bauhin's valve). Histology revealed a Dieulafoy lesion. Four months later, after normalisation and stabilisation of his haemoglobin level, the patient received a successful liver transplant. If the cause of occult gastrointestinal bleeding in a patient remains unclear despite regular endoscopic procedures, new techniques like videocapsule endoscopy and double-balloon enteroscopy may contribute to identifying the cause. This may lead to an exceptional finding such as a Dieulafoy lesion in the distal ileum.

Intestinal transplantation in The Netherlands: first experience and future perspectives.

Intestinal transplantation for intestinal failure is no longer an experimental procedure, but an accepted treatment for patients who fail total parenteral nutrition (TPN) therapy. Early referral for evaluation for small bowel transplantation has to be considered in patients with permanent intestinal failure who have occlusion of more than two major veins, frequent line-related septic episodes, impairment of liver function or an unacceptable quality of life. With the increased experience in post-transplant patient care and newer forms of induction (thymoglobulin, IL-2 receptor antagonists) and maintenance (tacrolimus) therapies the 1-year graft survival has increased to 65% for isolated and to 59% for liver/small bowel transplantation, and is further improving. Rejection, bacterial, fungal and viral (CMV, EBV) infection, post-transplant lymphoproliferative disease (PTLD) and graft versus host disease (GvHD) are the most common complications after intestinal transplantation. Although most of the long-term survivors are TPN-independent and have a good quality of life, the risk of the procedure and long-term adverse effects of immunosuppressive medication limits small bowel, or liver/small bowel transplantation only to patients with severe complications of TPN therapy.

Surgical intervention in patients with necrotizing pancreatitis.

BACKGROUND: This study evaluated the various surgical strategies for treatment of (suspected) infected necrotizing pancreatitis (INP) and patient referrals for this condition in the Netherlands. METHODS: This retrospective study included all 106 consecutive patients who had surgical treatment for INP in the period 2000-2003 in one of eight Dutch university medical centres including three teaching hospitals. Surgical approaches included an open abdomen strategy, laparotomy with continuous postoperative lavage, minimally invasive procedures or laparotomy with primary abdominal closure. The National Hospital Registration System was searched to identify patients with acute pancreatitis who were admitted to the 90 Dutch hospitals that did not participate in the present study. RESULTS: The overall mortality rate was 34.0 per cent, 70 per cent (16 of 23) for the open abdomen strategy, 25 per cent (13 of 53) for continuous peritoneal lavage, 11 per cent (two of 18) for minimally invasive procedures and 42 per cent (five of 12) for primary abdominal closure (P < 0.001). During the study interval, 44 (12.2 per cent) of 362 patients with acute pancreatitis who were likely to require surgical intervention had been referred to university medical centres. CONCLUSION: Laparotomy with continuous postoperative lavage is the surgical strategy most often used in the Netherlands. The results of the open abdomen strategy are poor whereas a minimally invasive approach seems promising.

[Small bowel transplantation as a treatment option for intestinal failure in children and adults]. / Dunnedarmtransplantatie als behandeling van darmfalen bij kinderen en volwassenen.

Small bowel transplantation for intestinal failure is no longer an experimental procedure, but an accepted treatment for patients where total parenteral nutrition (TPN) therapy for intestinal failure is unsuccessful. Early referral for screening for small bowel transplantation should be considered in patients with permanent intestinal failure who have occlusion of more than 2 major veins, frequent line-related septic episodes, impairment of liver function or an unacceptable quality of life. With the increased experience in post-transplant patient care and newer forms of induction (thymoglobulin, IL-2 receptor antagonists) and maintenance (tacrolimus) therapies, the 1-year graft survival has increased to 65% for isolated and to 59% for liver/small bowel transplantation and is further improving. Rejection, bacterial, fungal and viral (Cytomegalovirus, Epstein-Barr-virus) infections, post-transplant lymphoproliferative disease and graft versus host disease are the most common complications after intestinal transplantation. Although most of the long-term survivors are TPN-independent and have a good quality of life, the risk of the procedure and long-term adverse effects ofimmunosuppressive medication limits small bowel, or liver/small bowel transplantation only to patients with severe complications of TPN therapy.
