Background: Postoperative benign anastomotic stricture is associated with colorectal anastomosis following surgery for colorectal cancer. Endoscopic stricturotomy is a novel technique that has been demonstrated to be safe and effective for the treatment of colorectal anastomotic stricture in several case reports and series.
Objective: We designed this study to investigate the efficacy of endoscopic stricturotomy for postoperative benign anastomotic stricture in patients for colorectal cancer. The primary outcomes were stricture-recurrence-free survival and reoperation-free survival.
Design: This is a retrospective study.
Setting: This study presents a single-center experience.
Patients: This retrospective study included patients with colorectal cancer who underwent surgical resection and developed anastomotic stricture between January 2014 and June 2019 and were treated with endoscopic stricturotomy.
Main Outcome Measures: Immediate technical success of endoscopic stricturotomy and the factors associated with success and recurrence were investigated.
Results: Endoscopic stricturotomy was performed in 57 patients, and immediate technical success was achieved in 84% of the patients. The mean follow-up was 31.3 (15.8) months (range, 9-74 months). Postoperative benign anastomotic stricture recurred in 11 patients after initial successful endoscopic stricturotomy; 10 of the 11 recurrent patients accepted reoperation. Univariate and multivariate analysis indicated that length of stricture ≥1 cm was an independent risk factor for failure of the initial endoscopic stricturotomy (OR, 9.423; 95% CI, 1.729-51.350; p = 0.010) and the recurrence of postoperative benign anastomotic stricture after the initial endoscopic stricturotomy (OR, 13.521; 95% CI, 2.305-79.306; p = 0.004).
Limitations: The study was limited by its small sample size and retrospective design.
Conclusions: Endoscopic stricturotomy is a safe and effective technique for postoperative benign anastomotic stricture. However, if the length of the stricture is ≥1 cm, endoscopic stricturotomy may not be effective, and recurrence of postoperative benign anastomotic stricture is also likely.

Estricturotoma Endoscpica Para Pacientes Con Estriccin Anastomtica Benigna Postoperatoria Para El Cncer Colorrectal: ANTECEDENTES:La estenosis anastomótica benigna postoperatoria se asocia con anastomosis colorrectal después de la cirugía para el cáncer colorrectal. La estricturotomia endoscópica es una técnica novedosa que se ha demostrado que es segura y efectiva para el tratamiento de la estenosis anastomótica colorrectal en varios informes de casos o series.OBJETIVO:Diseñamos este estudio para investigar la eficacia de la estricturotomia endoscópica para la estenosis anastomótica benigna postoperatoria en pacientes con cáncer colorrectal. El resultado primario fue la supervivencia libre de restricción estricta y la supervivencia libre de reoperación.DISEÑO:Este es un estudio retrospectivo.CONFIGURACIÓN:Este estudio presenta una experiencia de un solo centro.PACIENTES:Este estudio retrospectivo incluyó pacientes con cáncer colorrectal que se sometieron a resección quirúrgica y desarrollaron estenosis anastomótica entre enero de 2014 y junio de 2019 y tratados con estricturotomia endoscópica.MEDIDAS PRINCIPALES DE RESULTADO:Éxito técnico inmediato y estenosurotomía endoscópica, los factores asociados con el éxito y la recurrencia.RESULTADOS:Se realizó estricturotomia endoscópica en 57 pacientes, y se logró un éxito técnico inmediato en el 84% de los pacientes. El seguimiento medio fue de 31,3 (15,8) meses (rango, 9 a 74 meses), el POBAS se repitió en 11 pacientes después del éxito inicial de ESt. 10 de los 11 pacientes recurrentes aceptaron la reoperación. El análisis univariado y multivariado indicó que la longitud de la estenosis ≥1 cm era un factor de riesgo independiente para el fracaso de la estricturotomia endoscópica inicial (odds ratio = 9,423; IC del 95% = 1.729-51.350; p = 0.010) y la recurrencia de estenosis anastomótica benigna postoperatoria después de la estricturotomia endoscópica inicial (odds ratio = 13,521; IC del 95% = 2,305-79,306; p = 0.004).LIMITACIONES:El estudio estuvo limitado por su pequeño tamaño de muestra y diseño retrospectivo.CONCLUSIONES:La estricturotomia endoscópica es una técnica segura y efectiva para la estructura anastomótica benigna postoperatoria. Sin embargo, si la longitud de la estenosis es ≥1 cm, la estricturotomia endoscópica puede no ser efectiva y también es probable que se repita la estenosis anastomótica benigna postoperatoria.

Aim: The aim of this study was to introduce the Esophagus-Sparing Anastomotic Narrowing Revision (ESANR) technique for the intraoperative management of anastomotic narrowing and to conduct a literature review to provide an algorithm for the management of narrowing and strictures that may develop secondary to esophagojejunostomy.
Methods: Three patients with anastomotic narrowing during esophagojejunostomy were analyzed between September 2019 and June 2024. The anastomotic narrowing was detected by intraoperative gastroscopy after reconstruction.

Stricture formation is a common complication after restorative proctocolectomy and Kock pouch surgery. Endoluminal functional lumen imaging probe (EndoFLIP) is a balloon catheter device that uses impedance planimetry to provide luminal pressure and dimension measurements. This case describes the first use of EndoFLIP to quantify the distensibility and diameter of a Kock pouch stricture before and after endoscopic balloon dilation and needle knife stricturotomy.

Background: Anastomotic strictures following colectomy and proctectomy are a significant cause of benign lower gastrointestinal tract (LGIT) obstruction, with a reported incidence of up to 30%. Endoscopic interventions such as balloon dilation, stricturotomy, mechanical dilation, electrocautery incision, and stent placement are utilized for management. This meta-analysis aimed to evaluate the efficacy and safety of endoscopic interventions for the management of benign LGIT anastomotic strictures.
