The Dutch multicenter experience of the Endo-Sponge treatment for anastomotic leakage after colorectal surgery
Anastomotic leakage is a feared complication following colorectal surgery and is associated with early and long-term morbidity and mortality. The presacral cavity as the result of leakage can be treated with an endo-sponge (B-Braun Medical). The aim of this study was to assess the effectiveness of endo-sponge treatment of the presacral cavity as the result of anastomotic leakage in the Netherlands. Between July 2006 and April 2008, 16 patients (M/F = 9:7) with median age 64 years (range 19-78 years) who underwent surgery for rectal cancer (n = 13) or ulcerative colitis (n = 3) were treated with the endo-sponge treatment after anastomotic leakage. Of the 16 patients, eight patients started with the endo-sponge treatment within 6 weeks after the initial surgery. In these patients the endo-sponge was placed after a median of 24 days (range 13-39 days) following surgery. In the remaining eight patients the endo-sponge treatment was started later than 6 weeks after the initial surgery. In this group there was a median of 74 days (range 43-1,602 days) between surgery and the start of endo-sponge placement. There was closure in six out of eight patients (75%) in the group that started with the endo-sponge treatment within 6 weeks of surgery compared with three out of eight patients (38%) in the group that started later (p = 0.315). Closure was achieved in a median of 40 (range 28-90) days with a median number of 13 sponge replacements (range 8-17). Endo-sponge placement can be helpful in the treatment for anastomotic leakage after colorectal surgery and might prevent a chronic presacral sinus. However, it is not yet clear if this new treatment modality results in quicker healin
Seton drainage prior to transanal advancement flap repair: useful or not?
Introduction: Transanal advancement flap repair (TAFR) provides a useful tool in the treatment of high transsphincteric fistulas. Recent studies indicate that TAFR fails in one out of three patients. Until now, no definite predictive factor for failure has been identified. Although some authors have reported that preoperative seton drainage might improve the outcome of TAFR, this could not be confirmed by others. We conducted the present study to assess the influence of preoperative seton drainage on the outcome of TAFR in a relatively large series. Methods: Between December 1992 and June 2008, a consecutive series of 278 patients [M/F = 179:99, median age 46 years (range, 19-73 years)] with cryptoglandular, transsphincteric fistula, passing through the upper or middle third of the external anal sphincter underwent TAFR. Patients were recruited from the colorectal units of two university hospitals (Erasmus Medical Center, Rotterdam, n = 211; and Leiden University Medical Center, Leiden, n = 67). Baseline characteristics did not differ between the two clinics. Sixty-eight of these patients underwent preoperative seton drainage for at least 2 months and until the day of the flap repair. Results: Median healing time was 2.2 months. In patients without preoperative seton drainage, the healing rate was 63%, whereas the healing rate was 67% in patients who underwent preoperative seton drainage. This difference was not statistically significant. No differences in healing rates were found between the series from Leiden and Rotterdam. Conclusion: Preoperative seton drainage does not improve the outcome of TAFR

Outcome of surgical treatment for fistula in ano in Crohn's disease
Background: Recurrence rates and long-term functional outcome after surgical treatment of anal fistula in Crohn's disease were assessed. Methods: A consecutive series of patients was treated for Crohn's fistula in ano; those without proctitis or active sepsis underwent surgery. Sex, seton usage, infliximaab, previous fistula surgery, history of segmental resection and smoking were examined as risk factors for recurrence. Continence was assessed by Vaizey scale and a colorectal Functional outcome questionnaire. Results were compared with institutional data for cryptoglandular fistulas. Results: Sixty-one patients were included, with a median follow-up of 79 (rangy 13-140) months. Twenty-four patients were treated with a seton, 28 by; fistulotomy and nine by mucosal advancement. For low fistulas, fistulotomy was used more frequently than the seton, whereas seton drainage was used for most higher fistulas. Recurrence occurred in five of 28 and five of nine patients after fistulotomy and advancement respectively. Soiling was reported by half of the patients treated by soon versus two-thirds and three-quarters of those treated by fistulotomy and advancement respectively. Functional outcomes were worse for all patient groups than for cryptoglandular fistulas. No risk factor was significant. Conclusion: Surgical outcome for high or complex Crohn's fistula in ano remains disappointing, and recurrence is unpredictabl
Histological identification of epithelium in perianal fistulae: a prospective study
A procedure often performed following fistulotomy and advancement flap is curettage of the fistula tract after fistulotomy or after closing the internal opening. Epithelialization of the fistula tract might prevent closure of the fistula tract. The aim of this study was to assess the incidence and origin of epithelialization of the fistula tract in patients with perianal fistulae undergoing fistulotomy. Only patients with low perianal fistulae that were surgically treated by fistulotomy were included. Surgical biopsies were taken from the fistula tract from three different locations; on the proximal side at the internal opening, in the middle of the fistula tract and near the distal end close to the external opening. In the study period, 18 patients with low perianal fistulae were included. In 15 of the 18 patients, squamous epithelium was found at least in one of the biopsies taken from the fistula tract. Epithelium was predominantly found near the internal opening. There was no relation between the duration of fistula complaints and the amount of epithelialization (P = 0.301). The amount of epithelium was not related to the presence of a history of fistula surgery (P = 1.000). This study demonstrated epithelialization in the fistula tract in the majority of the patients surgically treated by fistulotomy for low perianal fistulae. Curettage of perianal fistulae must therefore be considered an essential step in the surgical treatment of perianal fistul
"Turn laterally to the left!". The need for uniform C-arm communication terminology during orthopaedic trauma surgery
To avoid disturbed teamwork, unnecessary radiation exposure, and procedural delays, we designed and tested a uniform communication language for use in fluoroscopy-assisted surgical procedures. Input of surgeons and radiographers was used to create a set of commands. The potential benefit of this terminology was explored in an experimental setting. There was a tremendous diversity in the currently used terminology. Use of the newly designed terminology showed a reduction of procedural time and amount of images needed. Our first standardized Dutch language terminology can reduce total fluoroscopy time, number of images acquired, and potentially radiation exposure. For Dutch speaking colleagues, the developed terminology is freely available for use in their O
The persisting presacral sinus after anastomotic leakage following anterior resection or restorative proctocolectomy
Aim Despite improvements in anastomotic technique, anastomotic leakage is frequently encountered following anterior resection. This can eventually evolve into a presacral sinus. This study assessed the incidence, the natural course and the outcome of persisting presacral sinus. Method Patients who underwent low anterior resection (LAR) for cancer or restorative proctocolectomy (RPC) for ulcerative colitis or familial polyposis were eligible. Patients with anastomotic leakage or a presacral abscess were included. Outcome parameters included a persistent presacral sinus, or its closure and average time to closure and the stoma closure rate. Results Twenty-five patients were identified with a sinus after LAR (n = 20) or RPC (n = 5). A persistent sinus was present in nine (1%) of 834 patients after LAR and two (0.9%) of 229 patients after RPC. Definitive resolution of the sinus occurred in 12 (52%) of 23 assessable patients. This was achieved at a median of 340 days (range 23-731 days). At final follow-up, nine of the 23 patients had permanent faecal diversion because of recurrent abscess or persistent sinus formation, seven after LAR and two after RPC. Conclusion A significant proportion of patients with anastomotic leakage after rectal surgery develop a chronic sinus, of which only half heal over time. Persisting sinus is the main reason for a permanent stom
Systematic review of dysplasia after restorative proctocolectomy for ulcerative colitis
BACKGROUND: The aim of this systematic review was to assess the prevalence and site of dysplasia after restorative proctocolectomy (RPC) for ulcerative colitis (UC), and to identify risk factors that could be used in a surveillance programme. METHODS: Medical databases were searched for potentially relevant publications between 1978 and 2006. Studies that dealt with RPC for UC and postoperative surveillance were included. Two researchers independently performed study selection, quality assessment, data extraction and analysis. RESULTS: Twenty-three observational studies and case series were included, with a total of 2040 patients. The pooled prevalence of confirmed dysplasia in the pouch, anal transitional zone or rectal cuff was 1.13 (range 0-18.75) per cent. The prevalence of high-grade dysplasia, low-grade dysplasia and indefinite for dysplasia was 0.15 (range 0-4.49), 0.98 (range 0-15.62) and 1.23 (range 0-25.28 per cent) respectively. Dysplasia was equally frequent in the pouch and rectal cuff or anal transitional zone. Dysplasia and cancer identified before or at operation seemed to be significant predictors of the development of dysplasia. Pouchitis and duration of follow-up were not of predictive value. CONCLUSION: Although based on low-level evidence from uncontrolled studies, the prevalence of dysplasia observed after RPC was remarkable. A surveillance programme that takes into account the risk factors found is therefore advocate
Intestinal barrier function in patients undergoing colectomy
The aim of this pilot study was to determine whether the type of approach (open or laparoscopic) and the order of devascularization during laparoscopic colectomy affect intestinal barrier function, local inflammatory response and clinical outcome. Twenty-two patients undergoing elective colectomy from April 2006 to July 2008 were randomized to two sequences of vascular ligation, starting with either the inferior mesenteric artery or the ileocolic artery. Eighteen patients scheduled for open surgery served as a prospective control group. To assess the intestinal barrier function, release of intestinal fatty-acid binding protein (I-FABP; a marker of mucosal injury and ischaemia) was measured pre- and postoperatively. Mesenteric lymph nodes were harvested to assess the expression of inflammatory mediator-related genes using multiplex ligation probe amplification. The study was registered under NTR1025. Laparoscopic devascularization starting at the ileocolic artery resulted in a significantly increased excretion of I-FABP over time (P = 0.002). In this group, the I-FABP levels were significantly increased on postoperative days 1 and 3 compared with preoperative values (P = 0.011 and P = 0.001, respectively). There were no differences in expression of inflammatory mediator-related genes or postoperative morbidity among the groups. In this pilot study, devascularization commencing at the ileocolic artery during laparoscopic colectomy was associated with prolonged intestinal mucosal ischaemi
