Perianal Fistulizing Crohn's Disease: Utilizing the TOpClass Classification in Clinical Practice to Provide Targeted Individualized Care.

BACKGROUND & AIMS: Perianal fistulation is a challenging phenotype of Crohn's disease, with significant impact on quality of life. Historically, fistulae have been classified anatomically in relation to the sphincter complex, and management guidelines have been generalized, with lack of attention to the clinical heterogenicity seen. The recent 'TOpClass classification system' for perianal fistulizing Crohn's disease (PFCD) addresses this issue, and classifies patients into defined groups, which provide a focus for fistula management that aligns with disease characteristics and patient goals. In this article, we discuss the clinical applicability of the TOpClass model and provide direction on its use in clinical practice. METHODS: An international group of perianal clinicians participated in an expert consensus to define how the TOpClass system can be incorporated into real-life practice. This included gastroenterologists, inflammatory bowel disease surgeons, and radiologists specialized in PFCD. The process was informed by the multi-disciplinary team management of 8 high-volume fistula centres in North America, Europe, and Australia. RESULTS: The process produced position statements to accompany the classification system and guide PFCD management. The statements range from the management of patients with quiescent perianal disease to those with severe PFCD requiring diverting-ostomy and/or proctectomy. The optimization of medical therapies, as well as the use of surgery, in fistula closure and symptom management is explored across each classification group. CONCLUSION: This article provides an overview of the system's use in clinical practice. It aims to enable clinicians to have a pragmatic and patient goal-centered approach to medical and surgical management options for individual patients with PFCD.

Protocol of the LATFIA trial (Laser Assisted Treatment of Fistula in Ano): a multicentre, prospective, randomized controlled trial comparing fistula-tract laser closure (FiLaC™) with rectal advancement flap for high trans-sphincteric fistulas.

AIM: Anal fistula is one of the most common anal diseases, affecting between 1 and 3 per 10 000 people per year. Symptoms have a potentially severe effect on a patient's quality of life. Surgery is the mainstay of treatment, aiming to cure the fistula and preserve anal sphincter function. Rectal advancement flap (RAF) is currently the gold standard treatment but has recurrence rates varying between 20% and 50% and might lead to disturbance of continence. The aim of the trial described in this work is to discover if the minimally invasive fistula tract laser closure (FiLaC™) technique could achieve higher healing rates and a better functional outcome than RAF. METHOD: We will perform a randomized prospective multicentre noninferiority study of the treatment of high trans-sphincteric perianal fistulas, comparing FiLaC™ with RAF in terms of fistula healing, recurrence rate, functional outcome and quality of life. Primary and secondary fistula healing will be evaluated at 26 and 52 weeks' follow-up. Quality of life will be evaluated using the SF-36 questionnaire, the Faecal Incontinence Quality of Life Scale questionnaire and the Vaizey score at 3, 6, 12 and 26 weeks postoperatively. CONCLUSION: High trans-sphincteric fistulas have a potentially severe effect on a patient's quality of life. Classical treatment with RAF is a time-consuming invasive procedure. The LATFIA trial aims to compare FiLaC™ with the gold standard treatment with RAF. In case of noninferiority, FiLaC™ treatment could be standardized as a first line treatment for high trans-sphincteric fistulas. Better conservation of the patient's anal sphincter function could possibly be obtained. Likewise, we will report on the postoperative quality of life when applying these two techniques.

Symptom Assessment of Candidates for Sacral Neuromodulation Therapy With Urologic and Colorectal Conditions: Time for a Holistic Approach? Results and Findings From a Prospective Single-Center Study.

OBJECTIVES: Sacral neuromodulation (SNM) has evolved as a therapeutic intervention for various pelvic floor dysfunctions. However, the traditional approach primarily assesses discipline-specific symptoms, potentially overlooking holistic symptom improvement. We aimed to investigate whether a more comprehensive evaluation of pelvic floor symptoms enhances the assessment of SNM's test phase. MATERIAL AND METHODS: A prospective single-center trial (Optimization of Lower Urinary Tract Symptoms study) assessed SNM efficacy from March 2018 to December 2021 in patients from the urology department (UD) and colorectal surgery department (CRD) with a follow-up of 12 months. Objective and subjective outcomes were examined using diaries and patient-reported outcome measures. Statistical analyses were conducted to determine predictive factors for treatment success, expressed by the patient global impression of change. SPSS 29.0 was used. RESULTS: A total of 85 participants were included, displaying concomitant pelvic floor symptoms. After the first phase, significant improvements on all pelvic floor domains questionnaires were seen for both patients from UD and those from CRD. Although improvements were observed in bladder and bowel diaries, the traditional criteria for success (≥50% improvement in diary variables) did not consistently correlate with the patients' global impression of change. The absolute reductions in bother sum scores from multiple domains were significant predictors for the patients' global impression of change, outperforming discipline-specific assessments. Patients from UD benefit from both a urologic and pelvic pain symptom evaluation, and those from CRD, from both a urologic and bowel symptom evaluation. CONCLUSIONS: SNM shows positive effects across various pelvic floor domains, even beyond the primary intended indication of implantation. The rather rigid approach of patient selection of discipline-specific symptoms alone can be questioned. A more comprehensive evaluation encompassing various pelvic floor symptoms with the emphasis on subjective outcome measures could enhance SNM's efficacy assessment during the test phase. CLINICAL TRIAL REGISTRATION: The Clinicaltrials.gov registration number for the study is NCT05313984.

Interprofessional perspectives on care for patients with low anterior resection syndrome: A qualitative study.

AIM: Many patients are confronted with low anterior resection syndrome after rectal surgery. The perspectives of both healthcare professionals and patients on the impact of bowel problems may differ. This study aimed to explore experiences of healthcare professionals on how to provide, organise and optimise care for patients with low anterior resection syndrome from an interprofessional perspective. METHODS: An explorative qualitative design was used. Healthcare professionals were recruited in October 2018 in one general teaching hospital and one university hospital. Twenty one healthcare professionals from different professions caring for patients with low anterior resection syndrome were included in three focus group interviews. RESULTS: Healthcare professionals confirmed a lack of focus on patients who are confronted with low anterior resection syndrome and stated a need for a standardised approach of care. Additionally, three levels for care optimization emerged from the data: information before surgery with strong emphasis on the timing of informing, counselling of patients when confronted with low anterior resection syndrome and organisation of care. CONCLUSIONS: Healthcare professionals find it important to adopt the moment and amount of information to the coping mechanism and timing of the trajectory. Counselling and follow-up of patients with LARS should be organised proactively and should not remain restricted to pharmacological and nutritional advice. A possible strategy is to develop and implement late effects nurse-led clinics coordinated by the clinical nurse specialist.

Patient-reported outcomes after pelvic exenteration for colorectal cancer: A systematic review.

AIM: Pelvic exenteration (PE) carries high morbidity. Our aim was to analyse the use of patient-reported outcome measures (PROMs) in PE patients. METHOD: Search strategies were protocolized and registered in PROSPERO. PubMed, Embase, Cochrane Library, Google Scholar, Web of Science and ClinicalTrials.gov were searched with the terms 'patient reported outcomes', 'pelvic exenteration' and 'colorectal cancer'. Studies published after 1980 reporting on PROMs for at least 10 PE patients were considered. Study selection, data extraction, rating of certainty of evidence (GRADE) and risk of bias (ROBINS-I) were performed independently by two reviewers. RESULTS: Nineteen of 173 studies were included (13 retrospective, six prospective). All studies were low to very low quality, with an overall moderate/serious risk of bias. Studies included data on 878 patients with locally advanced rectal cancer (n = 344), recurrent rectal cancer (n = 411) or cancer of unknown type (n = 123). Thirteen studies used validated questionnaires, four used non-validated measures and two used both. Questionnaires included the Functional Assessment of Cancer Therapy-Colorectal questionnaire (n = 6), Short Form Health Survey (n = 6), European Organization for Research and Treatment for Cancer (EORTC) Quality of Life Questionnaire C30 (n = 6), EORTC-CR38 (n = 4), EORTC-BLM30 (n = 1), Brief Pain Inventory (n = 2), Short Form 12 (n = 1), Assessment of Quality of Life (n = 1), Short Form Six-Dimension (n = 1), the Memorial Sloan Kettering Cancer Center Sphincter Function Scale (n = 1), the Cleveland Global Quality of Life (n = 1) or other (n = 4). Timing varied between studies. CONCLUSIONS: Whilst the use of validated questionnaires increased over time, this study shows that there is a need for uniform use and timing of PROMs to enable multicentre studies.

Primary care providers' knowledge about the therapeutic management of refractory pelvic floor dysfunctions in Flanders, Belgium: a cross-sectional study.

BACKGROUND: Pelvic floor dysfunctions (PFD) are prevalent conditions in primary care practice. Basic knowledge of second-line therapies among primary care providers (PCPs) is indispensable to well-inform refractory patients and improve their access to specialized care. OBJECTIVES: Getting insight into the extent of knowledge about second-line therapies for refractory PFD among PCPs in Flanders, Belgium. METHODS: From January to March 2019 Flemish PCPs participated in the OptiLUTS trial - Part A (EC/2018/0244), by the completion of a 22-item online Dutch questionnaire. Prevalence of PCPs having awareness about sacral neuromodulation (SNM), intradetrusor botulinum toxin injections (BTX) and percutaneous tibial nerve stimulation (PTNS) was explored. Descriptive statistics, univariate analyses, and multiple logistic regression analyses were performed. RESULTS: Sixty PCPs, 55% GPs, 45% GP trainees, median age 29 years, participated. Respectively, 90, 73 and 5% had ever heard about BTX, SNM and PTNS. The profession was an independent predictive factor for never having heard of SNM therapy, GPs being more likely to have a lack of knowledge than trainees (OR = 29, 95%CI [1.9-442.5]). Ninety-three percent want to learn more about these therapies. CONCLUSION: There is a margin for improvement in the knowledge of PCPs regarding therapies for refractory PFD. Awareness among PCPs should be increased for the optimization of patient care.

Symptomatic gastric involvement in a parastomal hernia: uncommon presentation.

Introduction: A parastomal hernia (PSH) is the most common complication of a stoma creation. The PSH contents normally consist of mobile abdominal structures, i.e. omentum and small or large bowel loops. A herniated stomach is thereby very rare, given that only eight cases are reported in the literature.Patients and methods: Two female patients with clinical symptoms of gastric involvement in a PSH were admitted in our centre.Results: Computed tomography (CT) imaging, nasogastric decompression and an efficient operative intervention ensured a good clinical outcome in both patients, but with a long hospital stay and temporary gastroparesis in one patient. Regarding our two cases and the eight cases reported in the literature, mainly older females with colostomies are at risk and most of them need surgery. Conclusions: In patients presenting with obstructive symptoms, one should be aware of a possible gastric outlet obstruction because of its involvement in a PSH, although sporadic. Surgery might be considered as the treatment of choice because conservative treatment mostly fails. Earlier surgery might perhaps also reduce postoperative hospital stay and gastroparesis.

Intraoperative radiation therapy for rectal cancer and recurrent intra-abdominal sarcomas.

PURPOSE: The aim of this study was to evaluate the effect of high-dose-rate intraoperative radiation therapy (HDR-IORT) in a multimodality treatment on the local control (LC) and the overall survival (OS) rate in locally advanced rectal cancer (LARC), locally recurrent rectal cancer (LRRC) and recurrent intra-abdominal sarcomas (RS). MATERIALS AND METHODS: A retrospective analysis was performed on 27 patients who were treated with radical resection and HDR-IORT between April 2007 and January 2017. Patient, tumor and surgical characteristics were analyzed and the perioperative (<30 days) and long-term complications (>30 days) were assessed and graded. RESULTS: None of the patients with LARC (n = 4) developed a local recurrence and all patients were still alive at the end of the follow-up. The LC rates of LRRC (n = 17) after one and three years were respectively 48% and 40% and the one, three and five years OS were respectively 93%, 62% and 44%. For RS (n = 6), the LC rates after one and three years were both 33% and the one and three years OS rate were respectively 83% and 46%. CONCLUSIONS: The results of our study show that HDR-IORT could be a valuable asset in the multimodality management of LARC, LRRC and RS.

High post-operative pain scores despite multimodal analgesia in ambulatory anorectal surgery: a prospective cohort study.

Background: Ambulatory surgery for anorectal procedures has become widely accepted. Recent reviews recommend a multimodal approach to pain management. However, these recommendations are largely based on single intervention studies. Our goal was to evaluate post-operative pain in patients receiving a multimodal analgesic regimen. Methods: All patients undergoing an ambulatory anorectal procedure between December 2015 and September 2016 received a pain diary. Mean pain throughout the day and pain during defecation where recorded on day 0-14 and day 21 postoperatively using a numeric rating scale-11. Use of oral analgesics was also recorded. Results: Forty-two patients completed the pain diary. The use of local anesthetic infiltration did not result in a significant difference in pain scores in this study. Patients who received written information on postoperative pain management and hygienic measures had higher intake of oral analgesics. Despite receiving multimodal analgesic treatment, patients undergoing surgery for hemorrhoids or anal fissures reported pain scores ≥4 and used analgesics longer. Conclusion: A multimodal analgesic approach consisting of local anesthetic infiltration, multiple oral analgesics and written information seems to be insufficient for certain patient groups after ambulatory anorectal surgery. Especially patients undergoing surgery for hemorrhoids or an anal fissure should receive adequate analgesia. Pain during defecation is problematic and finding a solution for this problem remains challenging. Further research into the combined use of different analgesic modalities is recommended.

Long-term survival after multimodality therapy including surgery for metastatic esophageal cancer.

BACKGROUND AND OBJECTIVES: Esophageal cancer (EC) remains an aggressive disease with a poor survival. Management of metastatic EC is limited to palliative chemotherapy (CT). Scientific contributions regarding the role of surgery are scarce and controversial. We analysed outcome of surgically treated metastatic EC patients. METHODS: We retrospectively identified surgically treated metastatic EC patients from our esophagectomy database. The aim of this study was to evaluate surgical complications, pathological response, oncological outcome and mean survival of these aggressively treated stage IV cancer patients. RESULTS: Twelve stage IV patients with disease presentation limited to outfield lymph node (LN) and/or liver metastasis were treated with an aggressive multimodality treatment including surgery. Mean age was 58 years (75% male, 75% Adenocarcinomas). Median postoperative hospital stay was 15 d. Radiological anastomotic leakage occurred in one patient. In hospital, mortality was nil. Complete resection was achieved in all but one. Metastatic recurrence occurred in 64% of R0 resected patients. At date of censoring, after a median follow-up of 22 months, 50% of the surgical resected patients are still alive and 33% are free of disease recurrence. Kaplan-Meier curves show a possibility to long-term survival after aggressive multimodality therapy including surgery. CONCLUSIONS: In selected metastatic EC patients, multimodality treatment including surgery has an acceptable surgical outcome with a potentially long-term survival.

Effect of abdominopelvic sepsis on cancer outcome in patients undergoing sphincter saving surgery for rectal cancer.

BACKGROUND: In rectal cancer, the significance of abdominopelvic sepsis (APS) on metastatic tumor growth remains uncertain. We aimed to analyze the effect of abdominopelvic sepsis on long-term survival in patients undergoing restorative rectal cancer surgery. METHODS: Data were used from the Belgian PROCARE rectal cancer registry. The effect of abdominopelvic infection on survival was assessed in uni- and multivariable Cox regression models. The effect of clinical and pathological covariates was controlled by propensity score-based matching of cases with controls. The effect of abdominopelvic sepsis on the rate of local and metastatic recurrence was evaluated using crosstabulation and the Pearson χ2 test. RESULTS: In univariable analysis, the presence of APS was associated with significantly worse overall survival (HR 1.3, P = 0.025). After propensity score matching including age, BMI, tumor level, pTstage, pN stage, CRM, tumor grade, number of lymph nodes, and presence of lymphovascular invasion, the association of APS with OS was no longer significant (HR 1.26, 95%CI 0.92-1.74, P = 0.15). No differences were observed in the risk of local or metastatic recurrence (3.6% vs 2.9% and 13% vs 16.5%). CONCLUSIONS: In this analysis APS after rectal cancer resection was not significantly associated with OS, metastatic, or local recurrence.

Endovascular treatment of an iatrogenic perforation of the internal iliac vein.

We describe the case of a 48-year-old woman who developed a pelvic abscess after extensive surgery for recurrent ovarian cancer. While draining the abscess, a massive venous bleeding occurred. The bleeding was controlled by introducing a Foley catheter transrectally, occluding the perforated internal iliac vein. However, the catheter was positioned unintentionally in the inferior vena cava, causing hemodynamic instability. The iatrogenic perforation of the internal iliac vein was managed successfully with an endovascular approach using thrombin in combination with balloon-induced thrombosis. If iatrogenic venous bleeding occurs and the placement of a stent is precluded, balloon-induced thrombosis in combination with thrombin injection can be used successfully.

The Role of Abdominal Drain Cultures in Managing Abdominal Infections.

Intra-abdominal infections (IAI) are common in hospitalized patients, both in and outside of the intensive care unit. Management principles include antimicrobial therapy and source control. Typically, these infections are polymicrobial, and intra-operative samples will guide the targeted antimicrobial therapy. Although the use of prophylactic abdominal drains in patients undergoing abdominal surgery is decreasing, the use of drains to treat IAI, both in surgical and non-surgical strategies for abdominal infection, is increasing. In this context, samples from abdominal drains are often used to assist in antimicrobial decision making. In this narrative review, we provide an overview of the current role of abdominal drains in surgery, discuss the importance of biofilm formation in abdominal drains and the mechanisms involved, and review the clinical data on the use of sampling these drains for diagnostic purposes. We conclude that biofilm formation and the colonization of abdominal drains is common, which precludes the use of abdominal fluid to reliably diagnose IAI and identify the pathogens involved. We recommend limiting the use of drains and, when present, avoiding routine microbiological sampling.

Time Is Money in Case of a Button Battery Ingestion.

Button battery (BB) ingestion is a preventable pediatric health hazard with important morbidity and mortality due to complications. We present 3 pediatric patients with a complicated course after BB ingestion and discuss current guidelines. Urgent endoscopic removal is necessary for every BB impacted in the esophagus. A new strategy before endoscopic removal is the administration of honey or sucralfate. During endoscopy, rinsing the esophageal mucosae with acetic acid can neutralize the alkalic environment and prevent late complications. Prevention of ingestion needs to be pursued by increasing awareness and changing legislation of packaging of BB.

The OptiLUTS trial: improving care for therapy-resistant symptoms of the pelvis in Belgium.

INTRODUCTION/BACKGROUND: The management of therapy-resistant lower urinary tract symptoms (LUTS) and symptoms resulting from pelvic organ dysfunctions are subject to a high variability in the Belgian health-care centres. Practical guidelines and standardized patient clinical care pathways are often lacking and unadapted to the Belgian healthcare system. OBJECTIVES: The OptiLUTS trial aims to improve the multidisciplinary care of therapy-resistant symptoms of the pelvis in the Belgian healthcare setting. Project A aims for the improvement of knowledge of 2nd line treatments for LUTS among general practitioners. In project B a treatment algorithm for the overactive bladder syndrome and non-obstructive urinary retention will be developed specifically for Belgium. In Project C a patient customized sacral neuromodulation (SNM) care pathway will be set up. METHODS: Part A: Explorative study among general practitioners by distribution of a  questionnaire. Part B: Review of existing guidelines and use of the Delphi method to obtain expert consensus. Part C: A single center comparative study to compare outcomes before and after implementation of the SNM care pathway. Patients scheduled for the first stage of Interstim therapy™ will be included (N=100). Primary endpoints are the sensitivity and specificity of a new pelvic symptom assessment tool, the conversion to implant and explantation rates. CONCLUSION: There is a margin for improvement in the care process of patients with therapy-resistant symptoms of the pelvis in the Belgium healthcare system. In the OptiLUTs trial adapted guidelines and a clinical care pathway will be developed to standardize and increase the efficiency of care. TRIAL REGISTRATION: Approval for the trial by the Ethics Committee of the Ghent University hospital: EC/2018/0244.

A novel hybrid 3D endoscope zooming and repositioning system: Design and feasibility study.

BACKGROUND: Manipulation of the endoscope during minimally invasive surgery is a major source of inconvenience and discomfort. This report elucidates the architecture of a novel one-hand controlled endoscope positioning device and presents a practicability evaluation. METHODS AND MATERIALS: Setup time and total surgery time, number and duration of the manipulations, side effects of three-dimensional (3D) imaging, and ergonomic complaints were assessed by three surgeons during cadaveric and in vivo porcine trials. RESULTS: Setup was accomplished in an average (SD) of 230 (120) seconds. The manipulation time was 3.87 (1.77) seconds for angular movements and 0.83 (0.24) seconds for zooming, with an average (SD) of 30.5 (16.3) manipulations per procedure. No side effects of 3D imaging or ergonomic complaints were reported. CONCLUSIONS: The integration of an active zoom into a passive endoscope holder delivers a convenient synergy between a human and a machine-controlled holding device. It is shown to be safe, simple, and intuitive to use and allows unrestrained autonomic control of the endoscope by the surgeon.

Primary intestinal aspergillosis resulting in acute intestinal volvulus after autologous stem cell transplantation in a patient with relapsed non-Hodgkin lymphoma: report on a rare infectious complication and a review of the literature.

Objectives: Since primary intestinal aspergillosis is a severe infectious complication with a high morbidity and mortality in immunocompromised patients, we want to draw attention to this rare entity and the importance of early recognition. Methods: We report a case of documented primary intestinal aspergillosis in a patient receiving an autologous stem cell transplantation (SCT). Furthermore, this article gives a short reflection on the occurrence of invasive aspergillosis in autologous SCT and the value of serum galactomannan levels based on literature search and linked with the case. Results: In this case the patient presented on day +8 after autologous SCT for a relapsed diffuse large B-cell lymphoma with an acute abdomen with urgent need for surgical intervention. Biopsy revealed the presence of fungal colonies due to aspergillosis and voriconazole was started. Until that day the systematically taken serum galactomannan tests were all negative or pending. Initially there was some resistance to perform surgery in the presence of neutropenia and thrombocytopenia but in the end it provided the definitive diagnosis and should not be delayed. Until now this patient is in good health and retains a complete remission. Conclusion: With this case, we would like to emphasize that early recognition of primary intestinal aspergillosis is of the utmost importance as it is a rare but serious infectious complication. It should be included in the differential diagnosis of neutropenic patients with sudden onset abdominal pain and ongoing fever, even in the absence of a positive serum galactomannan.

Near-infrared fluorescence guided esophageal reconstructive surgery: A systematic review.

BACKGROUND: After an esophagectomy, the stomach is most commonly used to restore continuity of the upper gastrointestinal tract. These esophago-gastric anastomoses are prone to serious complications such as leakage associated with high morbidity and mortality. Graft perfusion is considered to be an important predictor for anastomotic integrity. Based on the current literature we believe Indocyanine green fluorescence angiography (ICGA) is an easy assessment tool for gastric tube (GT) perfusion, and it might predict anastomotic leakage (AL). AIM: To evaluate feasibility and effectiveness of ICGA in GT perfusion assessment and as a predictor of AL. METHODS: This study was designed according to the PRISMA guidelines and registered in the PROSPERO database. PubMed and EMBASE were independently searched by 2 reviewers for studies presenting data on intraoperative ICGA GT perfusion assessment during esophago-gastric reconstruction after esophagectomy. Relevant outcomes such as feasibility, complications, intraoperative surgical changes based on ICGA findings, quantification attempts, anatomical data and the impact of ICGA on postoperative anastomotic complications, were collected by 2 independent researchers. The quality of the included articles was assessed based on the Methodological Index for Non-Randomized Studies. The 19 included studies presented data on 1192 esophagectomy patients, in 758 patients ICGA was used perioperative to guide esophageal reconstruction. RESULTS: The 19 included studies for qualitative analyses all described ICGA as a safe and easy method to evaluate gastric graft perfusion. AL occurred in 13.8% of the entire cohort, 10% in the ICG guided group and 20.6% in the control group (P < 0.001). When poorly perfused cases are excluded from the analyses, the difference in AL was even larger (AL well-perfused group 6.3% vs control group 20.5%, P < 0.001). The AL rate in the group with an altered surgical plan based on the ICG image was 6.5%, similar to the well perfused group (6.3%) and significantly less than the poorly perfused group (47.8%) (P < 0.001), suggesting that the technique is able to identify and alter a potential bad outcome. CONCLUSION: ICGA is a safe, feasible and promising method for perfusion assessment. The lower AL rate in the well perfused group suggest that a good fluorescent signal predicts a good outcome.
