The management of enteroatmospheric fistula (EAF) in open abdomen (OA) therapy is challenging and associated with a high mortality rate. The introduction of negative pressure wound therapy (NPWT) in open abdomen management significantly improved the healing process and increased spontaneous fistula closure. Retrospectively, we analysed 16 patients with a total of 31 enteroatmospheric fistulas in open abdomen management who were treated using NPWT in four referral centres between 2004 and 2014. EAFs were diagnosed based on clinical examination and confirmed with imaging studies and classified into low (<200 ml/day), moderate (200-500 ml/day) and high (>500 ml/day) output fistulas. The study group consisted of five women and 11 men with the mean age of 52·6 years [standard deviation (SD) 11·9]. Since open abdomen management was implemented, the mean number of re-surgeries was 3·7 (SD 2·2). There were 24 EAFs located in the small bowel, while four were located in the colon. In three patients, EAF occurred at the anastomotic site. Thirteen fistulas were classified as low output (41·9%), two as moderate (6·5%) and 16 as high output fistulas (51·6%). The overall closure rate was 61·3%, with a mean time of 46·7 days (SD 43·4). In the remaining patients in whom fistula closure was not achieved (n = 12), a protruding mucosa was present. Analysing the cycle of negative pressure therapy, we surprisingly found that the spontaneous closure rate was 70% (7 of 10 EAFs) using intermittent setting of negative pressure, whereas in the group of patients treated with continuous pressure, 57% of EAFs closed spontaneously (12 of 21 EAFs). The mean number of NPWT dressing was 9 (SD 3·3; range 4-16). In two patients, we observed new fistulas that appeared during NPWT. Three patients died during therapy as a result of multi-organ failure. NPWT is a safe and efficient method characterised by a high spontaneous closure rate. However, in patients with mucosal protrusion of the EAFs, spontaneous closure appears to be impossible to achieve.
BackgroundChronic anal fissure (CAF) is a linear split of the anoderm. The minimally invasive management of CAF such as botulinum toxin (BT) injection is recommended. However, the exact efficient dose of BT, number of injections per session and the injection sites are still debatable. The aim of this analysis was to assess the dose-dependent efficiency of botulinum toxin injection for CAF. MethodsPubMed and Web of Science databases were searched for terms: “anal fissure” AND “botulinum toxin.” Studies published between October 1993 and May 2015 were included and had to meet the following criteria: (1) chronic anal fissure, (2) prospective character of the study, (3) used simple BT injection without any other interventions and (4) no previous treatment with BT.ResultsA total of 1577 patients from 34 prospective studies used either Botox or Dysport formulations were qualified for this meta-analysis. A total number of BT units per session ranged from 5 to 150 IU, whereas the efficiency across analyzed studies ranged from 33 to 96 %. Surprisingly, we did not observe a dose-dependent efficiency (Spearman’s rank correlation coefficient, ρ = 0.060; p = 0.0708). Moreover, there were no BT dose-dependent postoperative complications or fecal incontinence and significant difference in healing rates compared BT injection into the anal sphincter muscles.ConclusionsBT injection has been an accepted method for the management of CAF. Surprisingly, there is no dose-dependent efficiency, and the postoperative incontinence rate is not related to the BT dosage regardless the type of formulation of botulinum neurotoxin used. Moreover, no difference in healing rate has been observed in regard to the site and number of injections per session.
This report reviews the most common surgical interventions and complications of chronic peritoneal dialysis (PD) patients. Based on the current knowledge as well as our experience we detail the role of these surgical procedures. We supplement the reported knowledge in the field with our own experience in this area. The areas discussed include early complications such as surgical wound hemorrhage, bleeding from the catheter, intestinal perforation and urinary bladder perforation, dialysate leakage through the wound, as well as late complications including catheter kinking or occlusion, retention of fluid in the peritoneal recess, hernias and hydrothorax, and encapsulating peritoneal sclerosis. We also briefly cover the surgical aspects of exit-site infection and peritonitis. An understanding by nephrologists of the role for surgical intervention in PD patients will improve their care and outcomes.
The protective effect of the ESJ against neuroma formation was confirmed by behavioral and histological analyses, showing outcomes comparable to the muscle burying technique-the criterion standard of neuroma management.
Negative pressure wound therapy (NPWT) has become a standard in the treatment of chronic and difficult healing wounds. Negative pressure wound therapy is applied to the wound via a special vacuum-sealed sponge. Nowadays, the endoscopic vacuum-assisted wound closure system (E-VAC) has been proven to be an important alternative in patients with upper and lower intestinal leakage not responding to standard endoscopic and/or surgical treatment procedures. Endoscopic vacuum-assisted wound closure system provides perfect wound drainage and closure of various kinds of defect and promotes tissue granulation. Our experience has shown that E-VAC may significantly improve the morbidity and mortality rate. Moreover, E-VAC may be useful in a multidisciplinary approach – from upper gastrointestinal to rectal surgery complications. On the other hand, major limitations of the E-VAC system are the necessity of repeated endoscopic interventions and constant presence of well-trained staff. Further, large-cohort studies need to be performed to establish the applicability and effectiveness of E-VAC before routine widespread use can be recommended.
