  • Video capsule endoscopy in pediatric patients with Crohn’s disease : a single-center experience of 180 procedures
  • 2018
  • Ingår i: Therapeutic Advances in Gastroenterology. - SAGE Publications. - 1756-283X. ; 11
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Video capsule endoscopy (VCE) is a noninvasive method enabling excellent visualization of the small bowel (SB) mucosa. The aim of this study was to examine the impact and safety of VCE performed in children and adolescents with suspected or established Crohn’s disease (CD). Methods: A total of 180 VCE examinations in 169 consecutive patients conducted in 2003–14 in a single center were retrospectively analyzed. The median age was 13 years (range 3–17 years) and indications for VCE were suspected (125 cases, 69%) and established (55 cases, 31%) CD. VCE was performed with a PillCam SB (Given Imaging, Yokneam, Israel) VCE system with 8–12 h of registration without bowel preparation. Results: A total of 154 of 180 (86%) patients swallowed the capsule and 26 (14%) had the capsule endoscopically placed in the duodenum. Patency capsule examination was performed in 71 cases prior to VCE to exclude SB obstruction. VCE detected findings consistent with SB CD in 71 (40%) examinations and 17 (9%) procedures showed minor changes not diagnostic for CD. A total of 92 (51%) examinations displayed normal SB mucosa. The capsule did not reach the colon within the recording time in 30 (17%) procedures and were defined as incomplete examinations. A change in diagnosis or therapy was recommended in 56 (31%) patients based on VCE results. Capsule retention occurred in one patient. Conclusions: VCE is a safe method in children with suspected or established CD. VCE often leads to a definitive diagnosis and has a significant impact on the clinical management of pediatric patients with CD.

  • Use of Oral Contraceptives and Breast Cancer Survival
  • 2016
  • Ingår i: International Journal of Womens Health and Wellness. - 2474-1353. ; 2:4
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: Oral contraceptives (OC) have been shown to give a transient increased breast cancer risk. However, studies on breast cancer survival after OC use are sparse and conflicting.Aim: The aim of this study was to examine previous use of OC in relation to survival after breast cancer diagnosis.Methods: Data was collected from Malmö Diet and Cancer Study, with baseline examinations between 1991 and 1996. Out of 17035 women who completed all study parts, 765 women with incident breast cancer were included in this study. Kaplan Meier and Cox Proportional Hazards analyses, with 95% confidence intervals (CI), were used to study OC in relation to breast cancer-specific and overall survival. All analyses were stratified on age at diagnosis.Results: Women who had ever used OC were younger and more often had grade III tumors than those who had never used OC. Breast cancer-specific survival in women who ever had used OC was better when adjusting for BMI, socioeconomic status as well as tumor characteristics. However, when adjusting for age at diagnosis, the results did not remain significant (0.68, CI 95% 0.39- 1.18). Stratified analyses on age at diagnosis (40-55, 56-70 and ≥ 71) showed no statistically significant associations.Conclusion: In this study we could not demonstrate a significant effect of OC use on breast cancer survival.

  • Endoscopic full-thickness biopsy, a novel method in the work up of complicated abdominal symptoms
  • 2018
  • Ingår i: Therapeutic Advances in Gastroenterology. - SAGE Publications. - 1756-283X. ; 11, s. 1-4
  • Tidskriftsartikel (refereegranskat)abstract
    • Gastrointestinal complaints without obvious organic causes confirmed by clinical laboratory analyses, endoscopy or radiology are often referred to functional entities. Irritable bowel syndrome (IBS) is the most common functional disorder in the gut. Careful examination of these patients may reveal other diagnoses of defined etiologies, e.g., enteric neuropathy, microscopic colitis, and primary Sjögre’s syndrome. The present case describes a young patient with incapacitating gastrointestinal symptoms presumed to be IBS, who underwent endoscopic full-thickness biopsy in sigmoid colon. Histopathological examination revealed degenerative enteric neuropathy, possibly secondary to chronic ischemia.

  • Endoscopic versus Laparoscopic Full-Thickness Biopsy in the Pathological Evaluation of the Enteric Nervous System
  • 2018
  • Ingår i: Case Reports in Gastroenterology. - S. Karger AG. - 1662-0631. ; 12:1, s. 32-40
  • Tidskriftsartikel (refereegranskat)abstract
    • A full-thickness biopsy of the bowel wall is required to evaluate the enteric nervous system. A patient with aggravating gastrointestinal symptoms underwent a laparoscopic full-thickness biopsy of the ileum and, 1 year later, an endoscopic full-thickness biopsy of the sigmoid colon. Both samples showed enteric neuropathy characterized by vacuolated and enlarged neurons. The length of the myenteric plexus was greater in the endoscopic (23 mm) compared to the laparoscopic (11 mm) biopsy, with fewer tissue artefacts in the laparoscopic approach. Clinical deterioration was paralleled by enteric neuropathy with an increase in the percentage of vacuolated and enlarged enteric neurons from 24 to 35%.

  • Adhesive Mechanisms of Histone-Induced Neutrophil-Endothelium Interactions in the Muscle Microcirculation.
  • 2015
  • Ingår i: European Surgical Research. - Karger. - 0014-312X. ; 56:1-2, s. 19-31
  • Tidskriftsartikel (refereegranskat)abstract
    • Extracellular histones released during cell damage have the capacity to cause tissue injury associated with increased leukocyte accumulation. However, the molecular mechanisms regulating histone-induced leukocyte recruitment remain elusive. The objective of this study was to examine the role of adhesion molecules in histone-dependent leukocyte accumulation by use of intravital microscopy of the mouse cremaster microcirculation.

  • A new needle holder facilitating palm grip suturing.
  • 2015
  • Ingår i: European Surgical Research. - Karger. - 0014-312X. ; 54:1-2, s. 55-63
  • Tidskriftsartikel (refereegranskat)abstract
    • The finger grip and the palm grip are the most common needle holder grips for hand suturing in surgery. The major advantages of the palm grip are an increased versatility and the possibility to apply controlled force. However, there is a risk for a potential loss of precision and uncontrolled movement of the needle when disengaging the ratchet mechanism of the palmed instrument. The purpose of this study was to develop a new needle holder, referred to as the Frimand needle holder (FNH), and evaluate surgeons' perception of it. It was designed to overcome the above-mentioned disadvantages, hence facilitating palm and finger grip suturing. Moreover, we evaluated suture precision and attitudes related to the use of the finger grip and the palm grip.

  • Endoscopic submucosal dissection of 301 large colorectal neoplasias : outcome and learning curve from a specialized center in Europe
  • 2018
  • Ingår i: Endoscopy International Open. - Georg Thieme Verlag KG. - 2364-3722. ; 6:11, s. 1340-1348
  • Tidskriftsartikel (refereegranskat)abstract
    • Background and study aims Endoscopic submucosal dissection (ESD) allows en bloc resection of large colorectal lesions but ESD experience is limited outside Asia. This study evaluated implementation of ESD in the treatment of colorectal neoplasia in a Western center. Patients and methods Three hundred and one cases of colorectal ESD (173 rectal and 128 colonic lesions) were retrospectively evaluated in terms of outcome, learning curve and complications. Results Median size was 4 cm (range 1 - 12.5). En bloc resection was achieved in 241 cases amounting to an en bloc resection rate of 80 %. R0 resection was accomplished in 207 cases (69 %), RX and R1 were attained in 83 (27 %) and 11 (4 %) cases, respectively. Median time was 98 min (range 10 - 588) and median proficiency was 7.2 cm 2 /h. Complications occurred in 24 patients (8 %) divided into 12 immediate perforations, five delayed perforations, one immediate bleeding and six delayed bleedings. Six patients (2 %), all with proximal lesions, had emergency surgery. Two hundred and four patients were followed up endoscopically and median follow-up time was 13 months (range 3 - 53) revealing seven recurrences (3 %). En bloc rate improved gradually from 60 % during the first period to 98 % during the last period. ESD proficiency significantly improved between the first study period (3.6 cm 2 /h) and the last study period (10.8 cm 2 /h). Conclusions This study represents the largest material on colorectal ESD in the west and shows that colorectal ESD can be implemented in clinical routine in western countries after appropriate training and achieve a high rate of en bloc and R0 resection with a concomitant low incidence of complications. ESD of proximal colonic lesions should be attempted with caution during the learning curve because of higher risk of complications.

  • Endoscopic submucosal dissection of malignant non-pedunculated colorectal lesions
  • 2018
  • Ingår i: Endoscopy International Open. - Georg Thieme Verlag. - 2364-3722. ; 6:8, s. 961-968
  • Tidskriftsartikel (refereegranskat)abstract
    • Background and study aimsEndoscopic submucosal dissection (ESD) is an established method for en bloc resection of large non-pedunculated colorectal lesions in Asia but dissemination of ESD in Western countries is limited. The aim of this study was to evaluate the role of ESD in the management of malignant non-pedunculated colorectal lesions in a European center.Patients and methods Among 255 patients undergoing colorectal ESD between 2014 and 2016, 29 cases were identified as submucosal invasive cancers and included in this study. The main outcomes were en bloc, R0 and curative resection as well as procedural time, complications and recurrence.Results Median tumor size was 40 mm (range 20 – 70 mm). Thirteen cancers were located in the colon and 16 were located in the rectum. Procedural time was 89 minutes (range 18 – 594 minutes). Complete resection was achieved in 28 cases, en bloc and R0 resection rates were 83 % and 69 %, respectively. Curative resection rate was 38 %. One case had a perforation in the sigmoid colon requiring emergency surgery. No significant bleeding occurred. Six patients underwent additional surgery after ESD, one of whom had residual tumor. One recurrence was detected in 20 patients that were followed-up endoscopically, median follow-up time was 13 months (range 2 – 30 months).Conclusion ESD seems to be a safe and effective method for treating non-pedunculated malignant colorectal lesions after careful patient selection and proper endoscopic training.

  • Forceps Biopsies Are Not Reliable in the Workup of Large Colorectal Lesions Referred for Endoscopic Resection : Should They Be Abandoned?
  • 2019
  • Ingår i: Diseases of the Colon and Rectum. - Springer. - 0012-3706. ; 62:9, s. 1063-1070
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Biopsies are routinely obtained in the workup of large colorectal polyps before endoscopic resection. OBJECTIVE: This study aimed to examine how reliable biopsies are in terms of reflecting the true histopathology of large colorectal polyps, in the clinical routine. DESIGN: This is a retrospective study. SETTINGS: Data from patients undergoing polypectomy of large colorectal polyps at the endoscopy unit, Skåne University Hospital Malmö, between January 2014 and December 2016 were scrutinized. PATIENTS: A total of 485 colorectal lesions were biopsied within 1 year before complete endoscopic removal. Biopsy-obtained specimens were compared with completely resected specimens in terms of concordance and discordance and if the final result was upgraded or downgraded. MAIN OUTCOME MEASURES: The primary outcome measured was the concordance between biopsy-obtained specimens and completely resected specimens. RESULTS: Median lesion size was 3 cm (range 1-11). In 189 cases (39%), biopsies did not provide a correct dysplastic grade compared with final pathology after complete resection. One hundred forty-three cases (29%) and 46 cases (9%) were upgraded and downgraded. The percentage of cases with discordant biopsy results was 40% in cases with 1 biopsy taken and 38% in cases where multiple biopsies had been sampled. Time from biopsy to complete resection did not influence the erroneous outcome of biopsies. Notably, the percentage of discordant biopsy results was 37% and 35% in lesions measuring 1 to 2 cm and 2 to 4 cm. However, this percentage increased to 48% in colorectal lesions larger than 4 cm. LIMITATIONS: This study was designed to reflect the clinical routine, the number of biopsies obtained and forceps technique were hence not standardized, which constitutes a limitation. CONCLUSIONS: This study demonstrates that cancer-negative forceps biopsies of large colorectal polyps, referred for endoscopic resection, are not reliable. Considering that endoscopic resection of lesions containing superficial cancer is plausible, the clinical value of forceps biopsies in lesions suitable for endoscopic resection is questionable.

LAS BIOPSIAS CON FÓRCEPS NO SON CONFIABLES EN EL ESTUDIO DE LAS LESIONES COLORRECTALES GRANDES REFERIDAS PARA RESECCIÓN ENDOSCÓPICA: ¿DEBERÍAN ABANDONARSE?: Las biopsias se obtienen de forma rutinaria en el estudio de pólipos colorrectales grandes previo a resección endoscópica. OBJETIVO: Analizar que tan confiables son las biopsias en cuanto a reflejar la verdadera histopatología de los pólipos colorrectales grandes, en la rutina clínica. DISEÑO:: Este es un estudio retrospectivo. AJUSTES: Los datos de pacientes sometidos a polipectomía de pólipos colorrectales grandes en la unidad de endoscopia, en Skåne University Hospital Malmö, entre enero de 2014 y diciembre de 2016 fueron examinados. PACIENTES: Un total de 485 lesiones colorrectales se biopsiaron dentro de un año antes de la resección endoscópica completa. Las muestras obtenidas mediante biopsia se compararon con las muestras completas resecadas en términos de concordancia y discordancia, y si el resultado final ascendió o disminuyó de categoría. PRINCIPALES MEDIDAS DE RESULTADO: Concordancia entre muestras obtenidas mediante biopsia y muestras completamente resecadas. RESULTADOS: La mediana de tamaño de lesiones fue de 3 cm (rango 1-11). En 189 casos (39%) las biopsias no proporcionaron un grado de displasia correcto en comparación con la patología final después de la resección completa. 143 casos (29%) y 46 casos (9%) ascendieron y descendieron de categoría, respectivamente. El porcentaje de casos con resultados de biopsia discordantes fue del 40% en los casos con una sola biopsia tomada y del 38% en los casos en los que se tomaron múltiples biopsias. El tiempo desde la biopsia hasta la resección completa no influyó en el resultado erróneo de las biopsias. Notablemente, el porcentaje de resultados de biopsia discordantes fue de 37% y 35% en lesiones que midieron 1-2 cm y 2-4 cm, respectivamente. Sin embargo, este porcentaje aumentó a 48% en lesiones colorrectales mayores de 4 cm. LIMITACIONES: Este estudio se diseñó para reflejar la rutina clínica, el número de biopsias obtenidas y la técnica de fórceps no fueron estandarizadas, lo que constituye una limitación. CONCLUSIONES: Este estudio demuestra que las biopsias con fórceps negativas a cáncer, de pólipos colorrectales grandes referidas para resección endoscópica, no son confiables. Teniendo en cuenta que la resección endoscópica de lesiones que contienen cáncer superficial es posible, el valor clínico de las biopsias con fórceps en lesiones aptas para la resección endoscópica es cuestionable.
