Surgical techniques for mesenteric lengthening in ileoanal pouch surgery:a systematic review

Aim: The key to successful construction of an ileal pouch–anal anastomosis (IPAA) following proctocolectomy in patients with ulcerative colitis or familial adenomatous polyposis is the ability of the pouch reservoir to reach the anus well vascularized and without tension. The aim of this systematic review was to provide an overview of previously described different surgical lengthening techniques to achieve adequate length for a tension-free IPAA. Method: Pubmed, Embase and Cochrane Library databases were systematically searched. Two reviewers conducted a systematic search with combinations of keywords for the surgical procedure and surgical lengthening techniques. All publications that reported one or more surgical lengthening techniques during IPAA surgery in adult patients were selected, consisting of reviews, cohort studies, case reports, human cadaver studies and expert opinions. The primary outcomes measured were the different surgical lengthening techniques and the step-by-step approach they involve that can be used during surgery to achieve adequate length for an IPAA. Results: Of 1577 records reviewed, 19 articles were included in this systematic review describing at least 1181 patients (i.e. one review, four retrospective studies, five human cadaver studies, two case reports and seven expert opinions). A total of six different surgical lengthening techniques with various subtechniques were found and described, consisting of pouch folding, construction of different types of pouches, stepladder incisions, skeletonization of vessels, division and ligation of mesenteric vessels and using an interposition vein graft. No prospective or randomized controlled trials were performed regarding this topic. Quality assessment showed a medium quality of the included studies. Conclusion: Different surgical lengthening techniques are described in a step-by-step approach to create adequate mesenteric length during IPAA surgery, in patients in whom the ileal pouch cannot reach the dentate line.</p

Chronic Inguinal Pain After Kidney Transplantation, a Common and Underexposed Problem

The incidence and impact of chronic inguinal pain after kidney transplantation is not clearly established. A high incidence of pain after inguinal hernia repair, a comparable surgical procedure, suggests an underexposed problem. Between 2011 and 2013, 403 consecutive patients who underwent kidney transplantation were invited to complete the Caroline Comfort Scale (CCS) and Visual Analog Scale (VAS) in order to assess the incidence of chronic inguinal pain and movement disabilities, complemented by questions regarding comorbidity during follow-up. The response rate was 58 % (n = 199) with a median follow-up of 22 months (IQR 12-30). In total, 90 patients (45 %) reported a CCS > 0 and 64 patients (32 %) experienced at least mild but bothersome complaints. Most inguinal complaints were reported during bending over and walking with a mean CCS score of 1.1 (SD +/- 2.2) and 1.2 (SD +/- 2.4), respectively. A high body mass index (BMI), delayed graft function, and the need for a second operation were associated with a higher CCS score on univariate analysis. Using multivariate analysis, only BMI (p = 0.02) was considered an independent risk factor for chronic inguinal pain. The incidence of chronic inguinal pain is a common though underexposed complication after kidney transplantation. More awareness to prevent neuropathic pain seems indicated

Nationwide Outcome of Tailored Surgery for Symptomatic Chronic Pancreatitis based on Pancreatic Morphology:Validation of the International guidelines

OBJECTIVE: To determine the nationwide use and outcome of tailored surgical treatment for symptomatic chronic pancreatitis (CP) as advised by recent guidelines.SUMMARY BACKGROUND DATA: Randomized trials have shown that surgery is superior to endoscopy in patients with symptomatic CP, although endoscopy remains popular Recent guidelines advice to "tailor surgery" based on pancreatic morphology meaning that the least extensive procedure should be selected based on pancreatic morphology. However, nationwide, and multicenter studies On tailored surgery for symptomatic CP are lacking.METHODS: Nationwide multicenter retrospective analysis of consecutive patients undergoing surgical treatment for symptomatic CP in all seven Dutch university medical centers (2010-2020). Outcomes included volume trend, major complications, 90-day mortality, postoperative opioid use and clinically relevant pain relief. Surgical treatment was tailored based on the size of the main pancreatic duct and pancreatic head (e.g. surgical drainage for a dilated pancreatic duct, and normal size pancreatic head).RESULTS: Overall, 381 patients underwent surgery for CP: 127 surgical drainage procedures ( 33%; mostly extended lateral pancreaticojejunostomy), 129 duodenum-preserving pancreatic head resections (DPPHR, 34%, mostly Frey), and 125 formal pancreatic resections (33%, mostly distal pancreatectomy). The annual surgical volume increased slightly (Pearson r=0.744). Mortality (90-day) occurred in 6 patients (2%), and was non-significantly lower after surgical drainage (0%, 3%, 2%; P =0.139). Major complications (12%, 24%, 26%; P =0.012), postoperative pancreatic fistula grade B/C (0%, 3%, 22%; P =0.038), surgical reintervention (4%, 16%, 12%; P =0.006), and endocrine insufficiency ( 14%, 21%, 43%; P &lt;0.001) occurred less often after surgical drainage. After a median follow-up of 11 months [IQR 3-23] good rates of clinically relevant pain relief ( 83%, 69%, 80%; P =0.082) were observed and 81% of opioid users had stopped using (83%, 78%, 84%, P =0.496).CONCLUSION: The use of surgery for symptomatic CP increased over the study period. Drainage procedures were associated with the best safety profile and excellent functional outcome, highlighting the importance of tailoring surgery based on pancreatic morphology.</p

Early Steroid Withdrawal Compared With Standard Immunosuppression in Kidney Transplantation - Interim Analysis of the Amsterdam-Leiden-Groningen Randomized Controlled Trial

BACKGROUND: The optimal immunosuppressive regimen in kidney transplant recipients, delivering maximum efficacy with minimal toxicity, is unknown. METHODS: The Amsterdam, LEiden, GROningen trial is a randomized, multicenter, investigator-driven, noninferiority, open-label trial in 305 kidney transplant recipients, in which 2 immunosuppression minimization strategies-one consisting of early steroid withdrawal, the other of tacrolimus minimization 6 months after transplantation-were compared with standard immunosuppression with basiliximab, corticosteroids, tacrolimus, and mycophenolic acid. The primary endpoint was kidney function. Secondary endpoints included death, primary nonfunction, graft failure, rejection, discontinuation of study medication, and a combined endpoint of treatment failure. An interim analysis was scheduled at 6 months, that is, just before tacrolimus minimization. RESULTS: This interim analysis revealed no significant differences in Modification of Diet in Renal Disease between the early steroid withdrawal group and the standard immunosuppression groups (43.2 mL/min per 1.73 m2 vs 45.0 mL/min per 1.73 m2, P = 0.408). There were also no significant differences in the secondary endpoints of death (1.0% vs 1.5%; P = 0.737), primary nonfunction (4.1% vs 1.5%, P = 0.159), graft failure (3.1% vs 1.5%, P = 0.370), rejection (18.6% vs 13.6%, P = 0.289), and discontinuation of study medication (19.6% vs 12.6%, P = 0.348). Treatment failure, defined as a composite endpoint of these individual secondary endpoints, was more common in the early steroid withdrawal group (P = 0.027), but this group had fewer serious adverse events and a more favorable cardiovascular risk profile. CONCLUSIONS: Based on these interim results, early steroid withdrawal is a safe short-term immunosuppressive strategy. Long-term outcomes, including a comparison with tacrolimus minimization after 6 months, will be reported in the final 2-year analysis

Multiple Renal Arteries in Kidney Transplantation:A Systematic Review and Meta-Analysis

Background: The use of grafts with multiple renal arteries (MRA) in renal transplantation has not been clearly established. Material/Methods: A systematic literature review used predefined terms to search PubMed, EMBASE, and the Cochrane Library for all studies since 1985 that included more than 50 MRA grafts. A total of 23 studies, comprising a total of 18,289 patients, were eligible to be included in the meta-analysis. Results: Patients who received an MRA graft compared to single renal artery (SRA) grafts showed significantly higher complication rates (13.8% vs. 11.0%, OR 1.393, p Conclusions: MRA grafts were associated with a higher risk of complication and delayed graft function but had comparable long-term outcomes for graft and patient survival

Successful Kidney and Lung Transplantation From a Deceased Donor With Blunt Abdominal Trauma and Intestinal Perforation

The number of organ donors is limited by many contraindications for donation and poor quality of potential organ donors. Abdominal infection is a generally accepted contraindication for donation of abdominal organs. We present a 43-year-old man with lethal brain injury, blunt abdominal trauma, and intestinal perforation. After withdrawal of life-sustaining treatment and circulatory arrest, a minilaparotomy confirmed abdominal contamination with intestinal content. After closure of the abdomen, organs were preserved with in situ preservation with an aortic cannula inserted via the femoral artery. Thereafter, the kidneys were procured via bilateral lumbotomy to reduce the risk of direct bacterial contamination; lungs were retrieved following a standard practice. There was no bacterial or fungal growth in the machine preservation fluid of both kidneys. All organs were successfully transplanted, without postoperative infection, and functioned well after 6 months. We hereby show that direct contamination of organs can be avoided with the use of in situ preservation and retroperitoneal procurement. Intestinal perforation is not an absolute contraindication for donation, although the risk of bacterial or fungal transmission has to be evaluated per cas

Outcome of pancreas transplantation from donation after circulatory death compared to donation after brain death

Introduction: To overcome the gap of organ shortage grafts from donation after circulatory death (DCD) can be used. This review evaluates the outcomes after DCD pancreas donation compared to donation after brain death (DBD). Materials and methods: A literature search was performed using Medline, Embase, and PubMed databases. All comparative cohort studies reporting the outcome after DCD and DBD pancreas transplantation were included. All data were assessed according to the Meta-analysis of Observational Studies in Epidemiology (MOOSE) guidelines. To evaluate the event rates, pooled odds ratios (ORs) as well as the 95% confidence intervals (CI) were calculated. Since the number of studies is small we used the random effects model only to overcome heterogeneity. Results: There is no difference in 1-year pancreas graft survival (OR 1.092, CI 95% 0.649-1.837, P = 0.741) or patient survival (OR 0.699, CI 95% 0.246-1.985, P = 0.502). Simultaneous pancreas-kidney (SPK) transplantation showed significantly higher graft survival rates compared to pancreas transplantation alone (87.2% vs. 76.6%, P <0.001 in DBD and 86.5% vs. 74.9%, P <0.001 in DCD). DCD SPK grafts show a higher delayed kidney graft function rate compared to DBD SPK-grafts (OR 0.209, CI 95% 0.104-0.421, P <0.001). There is significantly less pancreas graft thrombosis after DBD-donation (OR 0.567, CI 95% 0.340-0.946, P = 0.030). We found no difference in the HbA1c level at 1-year follow-up with a median of 5.4% in both groups and a mean of 5.63% (DCD) vs 5.43% (DBD). Discussion: DCD pancreas transplantation has comparable patient and 1-year graft survival rates and should be considered a safe alternative for DBD pancreas transplantation. (C) 2016 IAP and EPC.
