A case of rectal stricture associated with the use of a fecal management system / Caso de constrição retal associada ao uso de um Sistema de manejo fecal

Fecal management systems are widely used to prevent complications of fecal incontinence such as skin breakdown and pressure ulcers. However they are occasionally associated with complications such as bleeding and pressure necrosis of rectal mucosa. We present a patient with Clostridium difficile colitis with a prolonged hospital stay requiring the use of Flexi-Seal Fecal Management System who developed abdominal pain and distention with obstipation. Computed tomography of abdomen showed dilatation of small and large bowel loops with a transition point at rectosigmoid junction. Flexible sigmoidoscopy revealed the presence of a severe stricture at the rectosigmoid junction that was not amenable to endoscopic dilation. Surgical resection with an end-colostomy was performed to relieve the obstruction. To the best of our knowledge, this is the first reported case of a high-grade stricture due to use of bowel management system that needed bowel resection surgery. (AU)

Sistemas de manejo fecal são amplamente utilizados com o objetivo de evitar as complicações da incontinência fecal, além de avarias à pele e úlceras de decúbito. No entanto, ocasionalmente esses sistemas estão associados a complicações, como sangra- mento e necrose por pressão da mucosa retal. Apresentamos um paciente com colite por Clostridium difficile com prolongada permanência no hospital e que necessitou do uso doFlexi-Seal Fecal Management System; esse paciente veio a sofrer dores e distensão abdominal, juntamente com obstipação. A tomografia computadorizada do abdome revelou dilatação de alças de intestine delgado e grosso, com um ponto de transição na junção retossigmóidea. A sigmoidoscopia flexível revelou presença de grande constrição na junção retossigmóidea, que não permitia dilatação endoscópica. Realizamos ressecção cirúrgica com colostomia terminal, com o objetivo de aliviar a obstrução. Até onde vai nosso conhecimento, este é o primeiro caso relatado de constrição de alto grau causada pelo uso de um sistema de manejo intestinal necessitando de cirurgia de ressecção intestinal. (AU)

Intractable rectal stricture caused by hot water enema / 대한외과학회지

Rectal burns caused by hot water enema have been reported only occasionally and the majority of them were treated in a conservative manner. Although intractable rectal stricture caused by rectal burn is rare, it may be treated by endoscopic intervention or surgery. A 52-year-old woman who had used various methods of enema to treat her chronic constipation eventually undertook a hot water enema herself. After that, anal pain and constipation became aggravated prompting her to visit our clinic. Although various nonoperative treatments including endoscopic stenting were performed, her obstructive symptom did not improve and endoscopic findings had not changed. Hence, we performed a laparoscopic proctosigmoidectomy and transanal coloanal anastomosis with ileal diversion to treat the disease, and as a result, her obstructive symptom improved well. Corrective surgery such as resection of involved segment with anastomosis may be beneficial in relieving obstructive symptoms of an intractable rectal stricture caused by hot water enema.

Anastomotic Stricture after Colorectal Stapled Anastomosis

INTRODUCTION: Stapled anastomosis in the rectal cancer surgery has been already proven as a safe technique, maintaing secure suture and saving times compared to handsewn anastomosis. With the advancement of stapling device, the incidence of anastomotic leakage has decreased significantly. However, developement of anastomotic stricture has become a major postoperative complication. PURPOSE: An analysis of the clinical features and the predisposing factors of anastomotic stricture was made to identify its pathogenesis and to determine adequate procedure. METHODS: We analyzed 49 patients (8.1%) with the rectal stricture among 608 patients, undergone stapled anastomosis for the rectal cancer surgery at Asan Medical Center from Jan 1993 to Dec 1998. Rectal stricture was defined when index finger or colonoscope could not pass the anastomotic site (high grade), or could pass with difficulty(low grade). RESULTS: Underlying general diseases, e.g., DM, hypertension and cardiovascular disease was associated more frequently in patients with anastomotic stricture (20.4%) than patients without (10.8%) (P<0.05). The rate of postoperative major complications in patients with stricture was 22.4%, while that of anastomotic leakage was 6.1%. Development of anastomotic stricture was not associated with operative methods, age, anastomosis level, and postoperative radiotherapy. In patients with stricture, 34 patients (69.4%) were asymptomatic, and 15 patients were symptomatic. In treating symptomatic rectal stricture, only five patients performed dilation manually or by the Hegar dilator. CONCLUSIONS: Rectal stricture after stapled anastomosis might be associated with underlying diseases, and correlated with prolonged sanguinous drainage and ileus. Meticulous management of underlying disease and complete hemostasis during operation appear to be important to reduce the rate of rectal stricture.

A Case of Gastric Cancer with Rectal Metastasis Developing Rectal Stricture / 대한소화기내시경학회지

A 59-year old female was admitted to Yongdong Severance Hospital due to diarrhea and lower abdominal pain lasting for 2 months. She had a previous history of admission for stomach cancer on September 1995. At that time, she underwent total gastrectomy and gastroduodenostomy. The pathology of the specimen revealed a signet ring cell carcinoma of stomach. On admission, computerized tomography revealed rectal wall thickness and no evidence of lymph node enlargement in abdomen and pelvic cavity. Barium enema study showed stricture of rectum. After sigmoidoscopic biopsy, she was diagnosed as a rectal metastasis resulted in rectal stricture and underwent sigmoid loop colostomy. Hence we present a case of gastric cancer with rectal metastasis resulted in rectal stricture.

Endoscopic Prosthesis in Malignant Stricture / 대한소화기내시경학회지

Non-operative palliative treatment for malignant colonic obstruction can sometimes be accomplished by the insertion of anorectal tube, endoscopic balloon dilation or endoscopic laser therapy. But these methods have some disadvantages, such as limitaation of activity, need of repetitive treatment and high-risk of perforation. Endoscopic prosthesis is generally accepted as a safe, effective palliative treatment for malignant esophageal stricture, because this method has no above disadvantages. Neverthless, there is only a few experence with endoecopic prosthesis in malignant colorectal stricture over the world. We report two cases which were safely, effectively performed endoscopic prosthesis in palliative treatment for their malignant rectal strictures.
