    Get PDF
    Intestinal failure secondary to short bowel syndrome is still a very serious condition. Treatment consists of parenteral nutrition to provide nutrients and maintain body weight. During the last decades, intestinal lengthening procedures have become more available. The goal of this review is to discuss the results of the literature on the most commonly performed intestinal lengthening procedures. RECENT FINDINGS: Longitudinal Intestinal Lengthening, Serial Transverse Enteroplasty (STEP), and Spiral Intestinal Lengthening and Tailoring (SILT) are currently the most frequently reported intestinal lengthening procedures. The most recent literature of these procedures is described with respect to indication, technical details, complications, short and long-term outcome, and PN independence. SUMMARY: On the basis of indication, surgical complexity, complications, and clinical success, we conclude that the STEP procedure is probably the best choice for most centers

    BACKGROUND: Bowel dysfunction after low anterior resection is often assessed by determining the low anterior resection syndrome score. What is unknown, however, is whether this syndrome is already present in the general population and which nonsurgical factors are associated. OBJECTIVE: The purpose of this study was to determine the prevalence of minor and major low anterior resection syndrome in the general Dutch population and which other factors are associated with this syndrome. DESIGN: This was a cross-sectional study. SETTINGS: The study was conducted within the general Dutch population. PATIENTS: The Groningen Defecation and Fecal Continence Questionnaire was distributed among a general Dutch population-based sample (N = 1259). MAIN OUTCOME MEASURES: Minor and major low anterior resection syndrome were classified according to the scores obtained. RESULTS: The median, overall score was 16 (range, 0-42). Minor low anterior resection syndrome was more prevalent than the major form (24.3% vs 12.2%; p <0.001). Bowel disorders, including fecal incontinence, constipation, and irritable bowel syndrome were associated with the syndrome, whereas sex, age, BMI, and vaginal delivery were not. Remarkably, patients with diabetes mellitus were significantly more prone to experience minor or major low anterior resection syndrome. The ORs were 2.8 (95% CI, 1.8-4.4) and 3.7 (95% CI, 2.2-6.2). LIMITATIONS: We selected frequent comorbidities and other patient-related factors that possibly influence the syndrome. Additional important factors do exist and require future research. CONCLUSIONS: Minor and major low anterior resection syndrome occur in a large portion of the general Dutch population and even in a healthy subgroup. This implies that the low anterior resection syndrome score can only be used to interpret the functional result of the low anterior resection provided that a baseline measurement of each individual is available. Furthermore, because people with low anterior resection syndrome often experience constipation and/or fecal incontinence, direct examination and diagnosis of these conditions might be a more efficient approach to treating patient bowel dysfunctions

    Get PDF
    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

    Distal Duodenogastrostomy or Proximal Jejunogastrostomy in the Management of Ultra-Short Bowel

    Inflammatory bowel disease, vascular disease, volvulus, adhesions, or abdominal trauma may necessitate extensive small-bowel resection resulting in an ultra-short distal duodenal or jejunal stump. If this distal duodenal or short jejunal stump is too short for stoma creation and bowel continuity restoration is hazardous or not possible at all, a distal duodenogastrostomy or proximal jejunogastrostomy in combination with drainage of the stomach is an option to prevent stump leakage. Although successful, this distal duodenogastrostomy has been described only in very few patients and in older records. We reintroduced this technique and describe a recent series of patients that confirms its usefulness in certain conditions. The technique of the distal duodenogastrostomy or proximal jejunogastrostomy with gastric drainage was used for the management of the difficult distal duodenum stump in five critically ill patients undergoing extensive bowel resection. Four patients with small-bowel ischemia and one patient suffering from perforating Crohn's disease and small-bowel volvulus were treated successfully. The gastrostomies were subsequently converted to a duodenotransversostomy (in two patients) or the patients underwent small-bowel transplantation (two patients). One patient still has a jejunogastrostomy just after the duodenal-jejunal transition. In all five patients, the distal duodenogastrostomy or proximal jejunogastrostomy in combination with gastric drainage functioned well up to restoration of bowel continuity. In one patient, distal duodenogastrostomy and transabdominal gastric drainage functioned well for 5 years. No anastomotic leakage occurred. This procedure provides a feasible solution for an ultra-short bowel at emergency laparotomy. It enhances the surgical armamentarium and provides treatment options for these patients that were perhaps previously deemed unsalvageable

    Intestinal stenosis in Crohn's disease shows a generalized upregulation of genes involved in collagen metabolism and recognition that could serve as novel anti-fibrotic drug targets

    Background and Aims: Crohn's disease (CD) can be complicated by intestinal fibrosis. Pharmacological therapies against intestinal fibrosis are not available. The aim of this study was to determine whether pathways involved in collagen metabolism are upregulated in intestinal fibrosis, and to discuss which drugs might be suitable to inhibit excessive extracellular matrix formation targeting these pathways. Methods: Human fibrotic and non-fibrotic terminal ileum was obtained from patients with CD undergoing ileocecal resection due to stenosis. Genes involved in collagen metabolism were analyzed using a microfluidic low-density TaqMan array. A literature search was performed to find potential anti-fibrotic drugs that target proteins/enzymes involved in collagen synthesis, its degradation and its recognition. Results: mRNA expression of collagen type I (COL1A1, 0.76 ± 0.28 versus 37.82 ± 49.85, p = 0.02) and III (COL3A1, 2.01 ± 2.61 versus 68.65 ± 84.07, p = 0.02) was increased in fibrotic CD compared with non-fibrotic CD. mRNA expression of proteins involved in both intra- and extracellular post-translational modification of collagens (prolyl- and lysyl hydroxylases, lysyl oxidases, chaperones), collagen-degrading enzymes (MMPs and cathepsin-K), and collagen receptors were upregulated in the fibrosis-affected part. A literature search on the upregulated genes revealed several potential anti-fibrotic drugs. Conclusion: Expression of genes involved in collagen metabolism in intestinal fibrosis affected terminal ileum of patients with CD reveals a plethora of drug targets. Inhibition of post-translational modification and altering collagen metabolism might attenuate fibrosis formation in the intestine in CD. Which compound has the highest potential depends on a combination anti-fibrotic efficacy and safety, especially since some of the enzymes play key roles in the physiology of collagen

    Prolonged Organ Extraction Time Negatively Impacts Kidney Transplantation Outcome

    Get PDF
    Main Problem: Following cold aortic flush in a deceased organ donation procedure, kidneys never reach the intended 0–4°C and stay ischemic at around 20°C in the donor’s body until actual surgical retrieval. Therefore, organ extraction time could have a detrimental influence on kidney transplant outcome. Materials and Methods: We analyzed the association between extraction time and kidney transplant outcome in multicenter data of 5,426 transplant procedures from the Dutch Organ Transplantation Registry (NOTR) and 15,849 transplant procedures from the United Network for Organ Sharing (UNOS). Results: Extraction time was grouped per 10-min increment. In the NOTR database, extraction time was independently associated with graft loss [HR 1.027 (1.004–1.050); p = 0.022] and with DGF [OR 1.043 (1.021–1.066); p 80 min was associated with a 27.4% higher hazard rate of graft failure [HR 1.274 (1.080–1.502); p = 0.004] and such kidneys had 43.8% higher odds of developing DGF [OR 1.438, (1.236–1.673); p 30 min was associated with 14.5% higher odds of developing DGF [OR 1.145 (1.063–1.233); p < 0.005]. Discussion: Prolonged kidney extraction time negatively influenced graft survival in Dutch donors and increased DGF risk in all deceased donor recipients

    Diaphragm Pacing in Patients with Spinal Cord Injury:A European Experience

    Get PDF
    BACKGROUND: Patients with high spinal cord injury (SCI) are unable to breathe on their own and require mechanical ventilation (MV). The long-term use of MV is associated with increased morbidity and mortality. In patients with intact phrenic nerve function, patients can be partially or completely removed from MV by directly stimulating the diaphragm motor points with a diaphragm pacing system (DPS). OBJECTIVES: We describe our multicenter European experience using DPS in SCI patients who required MV. METHODS: We conducted a retrospective study of patients who were evaluated for the implantation of DPS. Patients evaluated for DPS who met the prospectively defined criteria of being at least 1 year of age, and having cervical injury resulting in a complete or partial dependency on MV were included. Patients who received DPS implants were followed for up to 1 year for device usage and safety. RESULTS: Across 3 centers, 47 patients with high SCI were evaluated for DPS, and 34 were implanted. Twenty-one patients had 12 months of follow-up data with a median DPS use of 15 h/day (interquartile range 4, 24). Eight patients (38.1%) achieved complete MV weaning using DPS 24 h/day. Two DPS-related complications were surgical device revision and a wire eruption. No other major complications were associated with DPS use. CONCLUSIONS: Diaphragm pacing represents an attractive alternative stand-alone treatment or adjunctive therapy compared to MV in patients with high SCI. After a period of acclimation, the patients were able to reduce the daily use of MV, and many could be completely removed from MV
