Background Cardiovascular biomarkers such as NT‐proBNP (N‐terminal pro‐B‐type natriuretic peptide) are used for heart failure risk stratification in patients with acquired heart disease, but there are limited data about its role in patients with congenitally corrected transposition of the great arteries. The current study aims to assess the role of serial NT‐proBNP measurements for risk stratification in adults with congenitally corrected transposition of the great arteries. Methods We studied adults with congenitally corrected transposition of the great arteries with ≥2 NT‐proBNP measurements (2003–2024). Temporal change in NT‐proBNP was calculated as relative change from baseline levels. Results Of 152 patients (age 47±13 years, 45% men), baseline NT‐proBNP was 539 (interquartile range, 193–1549) pg/mL, and relative change from baseline levels of NT‐proBNP was 34% (interquartile range, −11 to 67). Of 152 patients, 45 (30%) had cardiovascular events (heart failure hospitalization [n=29], ventricular assist device [n=5], heart transplantation [n=11], and death [n=10]), yielding a 10‐year incidence of 26%. Higher baseline NT‐proBNP and relative change from baseline levels were associated with cardiovascular events. Serial NT‐proBNP measurements had incremental prognostic value compared with baseline measurement. The correlates of higher NT‐proBNP levels were atrial fibrillation, hypertension, right ventricular dilation and dysfunction, and atrioventricular valve regurgitation. Renin–angiotensin–aldosterone system antagonist was associated with lower NT‐proBNP levels and lower risk of cardiovascular events. Conclusions NT‐proBNP testing is inexpensive, widely available, and noninvasive, making it well suited for longitudinal surveillance in adults with congenital heart disease. Most of the correlates for elevated NT‐proBNP levels were modifiable, providing target for therapeutic interventions.

BACKGROUND: Chronic anal fissures are a painful condition characterized by a tear in the anal mucosa. Botulinum toxin injection is a minimally invasive treatment option, but long-term effectiveness in recurrent or persistent cases remains unclear. OBJECTIVE: This study evaluates the long-term outcomes of botulinum toxin injections for the treatment of chronic anal fissures. DESIGN: This study is a retrospective review. SETTINGS: The study was conducted at a tertiary academic center. PATIENTS: Adults with chronic anal fissures treated with botulinum toxin between 2018 and 2023 were included. MAIN OUTCOME MEASURES: Short- and long-term healing, recurrence, or persistence after botulinum toxin injection. Persistent or recurrent fissure(s) were followed for outcomes after subsequent repeat injections or surgery (lateral internal sphincterotomy or fissurectomy). RESULTS: Among 161 patients, 45.3% (n = 73) experienced short-term healing after botulinum toxin as first-line therapy, but only 26% (n = 42) had sustained healing. Subsequent treatment patterns were similar for recurrent (n = 31) and persistent (n = 88) fissures: 35% versus 31% no further intervention, 55% versus 42% multiple subsequent injections, 10% versus 23% surgery, respectively. Sustained healing was achieved in 63% (n = 10/16) of patients who underwent surgery compared with 37% (n = 14/38) who had repeat botulinum toxin injections ( p = 0.06). Only 49% achieved sustained healing after a single injection, multiple injections, or injection(s) with surgery. Complications included 5 episodes of mild fecal incontinence in the botulinum toxin group and 2 instances of surgical site infection in the surgery group. LIMITATIONS: Limitations include a single-institution, retrospective study design and loss to follow-up. CONCLUSION: Botulinum toxin remains a valuable therapy for chronic anal fissures. Many patients have persistent or recurrent fissures after botulinum toxin injection and undergo additional interventions. Despite multiple interventions, only half of the patients achieved sustained healing, regardless of the treatment pattern. These data do not support the use of botulinum toxin over surgery for the treatment of chronic fissures, are helpful for counseling patients on the safety profile of each, and set expectations regarding the need for multiple interventions.

RESULTADOS A LARGO PLAZO DEL USO DE TOXINA BOTULÍNICA EN EL TRATAMIENTO DE FISURAS ANALES CRÓNICAS: UN ENFOQUE GRADUAL PARA EL MANEJO DE CASOS RECURRENTES Y PERSISTENTES ANTECEDENTES: Las fisuras anales crónicas son una afección dolorosa caracterizada por un desgarro en la mucosa anal. La inyección de toxina botulínica es una opción de tratamiento mínimamente invasiva, pero su eficacia a largo plazo en casos recurrentes o persistentes sigue sin estar clara. OBJETIVO: Evaluar los resultados a largo plazo de las inyecciones de toxina botulínica para el tratamiento de las fisuras. DISEÑO: Revisión retrospectiva. ENTORNO: Centro académico terciario. PACIENTES: Adultos con fisuras crónicas tratados con toxina botulínica entre 2018 y 2023. PRINCIPALES MEDIDAS DE RESULTADO: Curación a corto y largo plazo, recurrencia o persistencia después de la inyección de toxina botulínica. Se realizó un seguimiento de las fisuras persistentes o recurrentes para evaluar los resultados después de repetidas inyecciones o cirugía (esfinterotomía interna lateral o fisurectomía). RESULTADOS: Entre los 161 pacientes, el 45,3 % (n = 73) experimentó una curación a corto plazo tras la toxina botulínica como terapia de primera línea, pero solo el 26 % (n = 42) tuvo una curación sostenida. Los patrones de tratamiento posteriores fueron similares para las fisuras recurrentes (n = 31) o persistentes (n = 88): 35 % frente a 31 % sin intervención adicional, 55 % frente a 42 % con múltiples inyecciones posteriores, 10 % frente a 23 % con cirugía, respectivamente. Se logró una curación sostenida en el 63 % (n = 10/16) de los pacientes que se sometieron a cirugía, en comparación con el 37 % (n = 14/38) que recibió inyecciones repetidas de toxina botulínica ( p = 0,06). Solo el 49 % logró una curación sostenida después de una sola inyección, múltiples inyecciones o inyecciones con cirugía. Las complicaciones incluyeron 5 episodios de incontinencia fecal leve en el grupo de la toxina botulínica y dos casos de infección en el sitio quirúrgico en el grupo de la cirugía. LIMITACIONES: Estudio retrospectivo de una sola institución y pérdida de seguimiento. CONCLUSIÓN: La toxina botulínica sigue siendo una terapia valiosa para las fisuras anales crónicas. Muchos pacientes presentan fisuras persistentes o recurrentes tras la inyección de toxina botulínica y se someten a intervenciones adicionales. A pesar de las múltiples intervenciones, solo la mitad de los pacientes lograron una curación sostenida, independientemente del patrón de tratamiento. Estos datos no respaldan el uso de la toxina botulínica frente a la cirugía para el tratamiento de las fisuras crónicas, pero son útiles para asesorar a los pacientes sobre el perfil de seguridad de cada una y establecer expectativas con respecto a la necesidad de múltiples intervenciones.

Abstract Background Patients with Crohn disease (CD) face an elevated risk of developing small bowel adenocarcinoma (SBA), a malignancy characterized by late-stage diagnosis and poor prognosis. In this study we aimed to characterize surgical management and oncologic outcomes for CD-associated SBA. Methods A retrospective review was conducted across 3 tertiary IBD centers, analyzing 99 patients with CD who underwent surgery for SBA between 1992 and 2025. Data included patient demographics, CD history, surgical details, and oncologic outcomes. Results The median time from CD diagnosis to SBA was 25 years. The SBA diagnosis was incidental in 74.8% of cases, discovered during surgery for other complications. Tumors were predominantly located in the ileum (80.8%) and showed aggressive features: 56.6% were poorly differentiated (grade 3), and 85.9% were pathologically advanced (T3/T4 on TNM staging). Nodal involvement was present in 45.5% of patients, and 18.2% had distant metastases at diagnosis. A complete (R0) resection was achieved in 90.9% of surgeries, with a 30-day morbidity rate of 26.3%. After a median follow-up of 36 months, the distant recurrence rate was 28.3%, and overall mortality was 27.3% (18.2% cancer related). Conclusion In patients with long-standing CD, SBA is typically an incidental diagnosis made at an advanced stage. While high rates of complete surgical resection are possible, the prognosis remains guarded due to aggressive tumor biology and high recurrence rates. These findings highlight a critical need for improved risk stratification to guide surveillance and for the development of evidence-based adjuvant treatment strategies.

Background: Total mesorectal excision (TME) remains the gold standard for the resection of rectal cancer regardless of the modality: open, laparoscopic, or robotic. The transanal TME (TaTME) approach has been utilized to overcome the difficulties encountered with the dissection of tumors in the distal pelvis. Recently, a single-port robotic approach (rSPa) was introduced, where three arms and a camera emanate from a 2.5 cm diameter port. This report presents the first experience in the United States combining those two approaches (rSPa TaTME) in rectal cancer, evaluating its safety and oncologic outcomes. Methods: This is a retrospective review of our prospectively maintained rectal cancer database. Patient demographics, tumor characteristics, neoadjuvant treatment, and oncologic and surgical outcomes were recorded. Results: Between May 2022 and August 2024, ten patients (six females, four males) with a median age at surgery of 53 years (range: 38–85) and a mean BMI of 26 (±5) kg/m2 were included for analysis. The median distance of tumors from the anorectal junction was 3.2 cm (range: 2–5.3 cm). All patients had negative margins, with eight complete TME specimens, one near complete, and one incomplete. The mean number of lymph nodes harvested was 24 (±11). The average operative time was 351 (243–411) min. The average length of stay was four days. The ileostomy was reversed in nine out of ten patients. Six patients experienced complications within 30 days of surgery. There were no local or distal recurrences, with a mean follow-up of 20 months (range: 4–30). Conclusions: rSPa TaTME is a unique and innovative method of combining two minimally advanced approaches for the resection of distal rectal cancers, with acceptable surgical and oncologic outcomes.

BACKGROUND: Ulcerative colitis, total colectomy, and tofacitinib have all been associated with an increased risk of venous thromboembolism. OBJECTIVE: To determine whether preoperative tofacitinib exposure increases venous thromboembolism or other postoperative complications among patients with ulcerative colitis undergoing subtotal colectomy, total colectomy, or total proctocolectomy. DESIGN: Retrospective, case-controlled study at a single institution. SETTINGS: A tertiary referral center. PATIENTS: Adult patients with ulcerative colitis undergoing subtotal colectomy, total colectomy, or total proctocolectomy after 2018 who were taking tofacitinib within 30 days of surgery (n = 56) were compared to age- and sex-matched patients with ulcerative colitis undergoing the same surgeries but who were not exposed to tofacitinib (n = 56). MAIN OUTCOME MEASURE: The primary outcome was differences in the incidence of venous thromboembolism within 90 days of surgery based on tofacitinib exposure. Secondary outcomes were 90-day postoperative complications. RESULTS: Groups were well matched for age (non-tofacitinib: mean 35.2 years [SD 12.0], tofacitinib: 35.9 [SD 12.1], p = 0.36) and sex (41% women in each group, p = 1.00). Medical characteristics were similar between groups except for biological medication exposure 30 days before surgery (non-tofacitinib: 66%, tofacitinib: 36%, p = 0.004). Surgical characteristics did not differ between groups. Most patients were discharged on extended venous thromboembolism prophylaxis (non-tofacitinib: 80% and tofacitinib: 77%). Adjusted for biological exposure, there were no statistically significant differences in venous thromboembolism (non-tofacitinib exposed: 14%, tofacitinib exposed: 4%, p = 0.09) or other postoperative outcomes. LIMITATION: Retrospective, single institutional study. CONCLUSIONS: Among patients with ulcerative colitis undergoing total colectomy or proctocolectomy, exposure to tofacitinib was not associated with an increased risk of venous thromboembolism or other postoperative complications.

LA EXPOSICIÓN A TOFACITINIB NO AUMENTA LAS COMPLICACIONES POSOPERATORIAS ENTRE PACIENTES CON COLITIS ULCEROSA SOMETIDOS A COLECTOMÍA TOTAL: UN ESTUDIO RETROSPECTIVO DE CASOS Y CONTROLES ANTECEDENTES: La colitis ulcerosa, la colectomía total y el tofacitinib han sido asociados con un mayor riesgo de tromboembolismo venoso. OBJETIVO: Determinar si la exposición preoperatoria a tofacitinib aumenta la tromboembolia venosa u otras complicaciones posoperatorias entre pacientes con colitis ulcerosa sometidos a colectomía subtotal, colectomía total o proctocolectomía total. DISEÑO: Estudio retrospectivo de casos y controles en una sola institución. AJUSTES: Un centro de referencia terciario. PACIENTES: Los pacientes adultos con colitis ulcerosa sometidos a colectomía subtotal, colectomía total o proctocolectomía total después del año 2018 que se encontraron consumiendo tofacitinib dentro de los 30 días posteriores a la cirugía (n = 56) fueron comparados con pacientes con colitis ulcerosa de la misma edad y sexo sometidos a las mismas cirugías pero que no estuvieron expuestos a tofacitinib (n = 56). MEDIDA DE RESULTADO PRINCIPAL: El resultado primario fueron las diferencias en las incidencias de tromboembolismo venoso dentro de los 90 días posteriores a la cirugía según la exposición a tofacitinib. Los resultados secundarios fueron las complicaciones posoperatorias a los 90 días. RESULTADOS: Los grupos se encontraban bien emparejados por edad (sin tofacitinib: media 35,2 años [DE 12,0], tofacitinib: 35,9 [DE 12,1], p = 0,36) y sexo (41% mujeres en cada grupo, p = 1,00). Las características médicas fueron similares entre los grupos, excepto por la exposición a medicamentos biológicos 30 días antes de la cirugía (sin tofacitinib: 66 %, tofacitinib: 36 %, p = 0,004). Las características quirúrgicas no difirieron entre los grupos. La mayoría de los pacientes fueron dados de alta con profilaxis extendida para tromboembolismo venoso (sin tofacitinib: 80% y tofacitinib: 77%). Ajustado a la exposición biológica, no hubo diferencias estadísticamente significativas en el tromboembolismo venoso (no expuestos a tofacitinib: 14%, expuestos a tofacitinib: 4%, p = 0,09) u otros resultados posoperatorios. LIMITACIÓN: Estudio institucional único, retrospectivo. CONCLUSIÓN: Entre los pacientes con colitis ulcerosa sometidos a colectomía total o proctocolectomía, la exposición a tofacitinib no se asoció con un mayor riesgo de tromboembolismo venoso u otras complicaciones posoperatorias.

Abstract Surgical abdominal emergencies among patients with cerebral palsy (CP) are infrequently reported. The most commonly reported reason for urgent and emergent abdominal surgery among patients with CP is intestinal volvulus. Intestinal volvulus leads to obstruction and vascular compromise, potentially resulting in life-threatening ischemia and necrosis. Volvulus typically presents with abdominal pain and decreased bowel function. When patients are nonverbal and have baseline bowel dysfunction, symptoms of volvulus can be difficult to diagnose. Here, we present a case of an adult female patient with CP who presented with ischemic colitis with perforation and underwent emergency total colectomy and end-ileostomy. Her postoperative course was complicated by two episodes of intestinal volvulus that occurred one and three months after the initial operation. At the second presentation, she had global bowel ischemia due to the volvulus, which led to her death. We have reviewed and summarized the current literature regarding abdominal emergencies among patients with CP.
