RESUMO
PURPOSE: The Gamma3 nail (Stryker®) is an intramedullary device consisting of a proximal lag screw and distal interlocking screw. It is still unknown whether the screw locking mode could influence clinical outcomes. The aim of this study is to compare static and dynamic screw locking regarding their influence on surgical revisions and lag screw displacement. METHODS: A retrospective single-centre study was performed on patients ≥ 60 years admitted for a trochanteric fracture between September 2016 and January 2020. Surgical revisions and lag screw displacement were evaluated at 6 weeks and 1-year follow-up, respectively. RESULTS: A total of 142 patients were included for analysis. Surgical revisions were needed in 13 cases (9.2%). Indications included implant breakage (n = 3), lag screw cut-out (n = 3), lateral hip pain (n = 6) and non-union (n = 1). The number of surgical revisions was not different between static and dynamic locking (OR 2.55; 95%CI 0.73-8.56; p 0.142). The median lag screw displacement was 2.5 mm, which was similar for static and dynamic locking (2.3 mm versus 2.7 mm; p 0.785). CONCLUSION: The screw locking mode of the Gamma3 nail is not associated with a higher risk of surgical revisions. However, the design of the Gamma3 nail may not be suitable for static locking.

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 OR.

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 stoma.

AIM: 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. METHOD: 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. RESULTS: 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. CONCLUSIONS: In this pilot study, devascularization commencing at the ileocolic artery during laparoscopic colectomy was associated with prolonged intestinal mucosal ischaemia.

AIM: The risk of malignant changes in presacral tumours in children was investigated in relation to age at diagnosis, type of presentation and origin of the tumour. METHOD: A retrospective review was carried out in 17 patients surgically treated for congenital presacral masses over a 22-year period. RESULTS: Constipation was the main symptom in 14 (82%) of 17 patients. The lesions were evident on digital examination in 14 patients. Mature teratoma (n = 9, 64%) was the most common lesion, including three malignancies. Currarino syndrome was diagnosed in 10 (71%) patients. Two unclassified variant HLXB9 gene mutations were found in five (29%) patients who underwent genetic testing. CONCLUSION: Congenital presacral tumours in children were mostly mature teratomas, either as sacrococcygeal teratomas or as part of the Currarino syndrome. The risk of malignancy in patients older than 1 year necessitates early surgical resection.

AIM: 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. METHOD: 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. RESULTS: 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). CONCLUSION: 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 fistula.

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, infliximab, 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 (range 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 seton 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 unpredictable.

BACKGROUND: 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. METHODS: 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. RESULTS: 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). CONCLUSIONS: 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 healing.

OBJECTIVE: The endo-sponge was used in two patients in the treatment of anastomotic leakage following ileo-anal J-pouch reconstruction. Recently, local vacuum sponge treatment has shown to be effective to treat contained anastomotic leakage after low anterior anastomosis in rectal cancer patients. METHOD: Two patients (male, 18 years; female, 40 years) who underwent restorative proctocolectomy for ulcerative colitis developed localized anastomotic leakage without general peritonitis. This was endoscopically managed by transanal placement of an endo-sponge (B. Braun Medical B.V., Melsungen, Germany) after a diverting ileostomy was performed. RESULTS: The sponge was frequently replaced until resolution of the sinus was achieved in 35 and 56 days. CONCLUSION: Vacuum endo-sponge treatment can help anastomotic leakage after ileo-anal pouch surgery.

The aim of surgical treatment of perianal fistulas is to treat the patient's symptoms, with low recurrence rates and risk of incontinence. In recent years there have been developments regarding the classification and diagnosis ofperianal fistulas. MRI is the most appropriate diagnostic tool. In the hands of an experienced operator anal endosonography is a suitable, less expensive and readily-available alternative. As a result of developments in fistula surgery it is now more practical to classify perianal fistulas as low or high fistulas, as this has implications for the further treatment. Low perianal fistulas are defined as fistulas of which the fistula tract is located in the lower third of the external anal sphincter. High fistulas are fistulas in which the fistula tract runs through the upper two-thirds of the external sphincter muscle. Low perianal fistulas can be treated safely by fistulotomy. At present, rectal advancement is the gold standard for the surgical treatment of high transsphincteric perianal fistulas. The anal fistula plug might be an alternative for the treatment of high transsphincteric perianal fistulas.

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 advocated.
