BACKGROUND: Inflammatory polyps are common sequelae in patients with inflammatory bowel diseases (IBD). Those polyps can usually be removed with snare polypectomy. There were limited data evaluating the management of hot snare-resistant inflammatory polyps.METHODS: We reported on two cases with hot snare-resistant inflammatory polyps, one was a Crohn's disease (CD) patient with the polyp at the ileo-colonic anastomosis (ICA) and the other one was an ulcerative colitis (UC) patient with polyp at the pouch inlet.RESULTS: Sedated endoscopy was performed, which showed a large 2.5 cm pedunculated polyp at the ICA in the first patient and a large 5 cm pedunculated polyp at the pouch inlet in the second patient. Hot snare polypectomy was initially attempted, but failed in both patients. Then endoscopic needle knife polypectomy was performed, which helped complete polypectomy. Both procedures took approximately 25 minutes each. The patients tolerated the procedure well and continued to do well after the procedure. The final pathological diagnoses for both patients were inflammatory polyps with extensive fibrosis.CONCLUSIONS: Endoscopic needle knife-assisted polypectomy appeared to be an effective technique for the management of hot snare-resistant inflammatory polyps.

EXPERIÊNCIA: Pólipos inflamatórios são sequelas comuns em pacientes com doença intestinal inflamatória (DII). Geralmente esses pólipos podem ser removidos pela polipectomia por cauterização com laço. São limitados os dados que avaliam o tratamento de pólipos inflamatórios resistentes à cauterização por laço.MÉTODOS: Descrevemos dois casos com pólipos inflamatórios resistentes à cauterização por laço; um deles se tratava de paciente com doença de Crohn (DC) com o pólipo na anastomose íleo-colônica (AIC), e o outro era paciente de colite ulcerativa (CU) com pólipo na entrada da bolsa.RESULTADOS: Foi efetuada uma endoscopia com o paciente sedado, demonstrando um grande pólipo pedunculado (2,5 cm) na AIC do primeiro paciente e um grande pólipo pedunculado (5 cm) na abertura da bolsa no segundo paciente. Inicialmente, foi tentada polipectomia por cauterização com laço, que falhou nos dois pacientes. Foi então executada a polipectomia assistida por bisturi-agulha, que ajudou na polipectomia completa. Os dois procedimentos levaram 25 minutos cada. Os pacientes toleraram satisfatoriamente o procedimento e, depois da polipectomia, ficaram bem. Os diagnósticos patológicos finais para os dois pacientes foram pólipos inflamatórios com fibrose extensa.CONCLUSÕES: Ao que parece, a polipectomia endoscópica por bisturi-agulha é técnica efetiva para o tratamento de pólipos inflamatórios resistentes à cauterização por laço.

Pouch prolapse is a complication following the creation of restorative proctocolectomy. There is a paucity of information in the literature pertaining to its management. An ileal J pouch patient with dyschezia presented to our Pouch Center. Under sedation, pouchoscopy was performed with a gastroscope. We detected an anterior distal pouch mucosal prolapse, 1.5 cm in diameter, blocking the anal canal. The prolapsed mucosa was excised with hot snare under a retroflex view. There was no bleeding or perforation. The entire procedure took 25 minutes. The patient tolerated the procedure well and was discharged home 30 minutes after post-procedural observation. The patient reported the resolution of the dyschezia symptom. The histopathological examination of excised specimen showed small bowel mucosa and sub-mucosa with changes compatible with mucosal prolapse. Endoscopic hot snare appears to be feasible in the management of pouch mucosal prolapse. O prolapso da bolsa ileal é uma complicação que pode surgir após a criação da proctocolectomia restauradora. As informações na literatura são escassas quanto ao tratamento. Um paciente com bolsa ileal em "J" e apresentando disquezia deu entrada em nosso centro médico. Sob sedação, realizamos uma endoscopia da bolsa ileal. Detectamos uma bolsa distal anterior com prolapso da mucosa, com 1,5 cm de diâmetro, bloqueando o canal anal. O prolapso da mucosa foi retirado com alça diatérmica sob visão retroflexa. Não houve sangramento ou perfuração. A duração de todo o processo foi de 25 minutos. O paciente tolerou bem o procedimento e recebeu alta após 30 minutos de observação pós-procedimento. O paciente relatou a resolução do sintoma de disquezia. O exame histopatológico do espécime extirpado mostrou a mucosa e submucosa do intestino delgado com alterações compatíveis com o prolapso da mucosa. A alça diatérmica endoscópica parece ser viável no tratamento de prolapso da mucosa da bolsa ileal.
