Highlights • Pneumatosis intestinalis is characterized by the presence of air localizing in the submucosa and subserosa layers of the bowel wall. • Because of its risk of impending perforation, emergency surgery is generally required to be a definite treatment. • Colonic stenting can be used as a safe alternative procedure in the selected patient., Introduction Pneumatosis intestinalis is one of serious conditions following mechanical bowel obstruction. Emergency surgery is generally required to be a definite treatment in these patients of pneumatosis intestinalis, because of its risk of bowel ischemia and perforation. Since the operation in unprepared colon usually resulted in unfavorable outcome, the use of colonic stent is considered one of potential options as a bridge to definitive surgery. Presently, there is no widely published report of using colonic stent in these patients, particularly for stepping to curative surgery. Therefore, we herein report a case of obstructing sigmoid cancer with pneumatosis intestinalis who underwent successfully emergency metallic stent placement to convert from emergency to elective surgery. Presentation of case A 50-year-old woman presented with 3-day history of abdominal pain and obstipation. Abdominal computed tomography demonstrated a short segment of circumferential luminal narrowing at sigmoid colon, the presence of pneumatosis intestinalis at cecum, including ascending colon, and no extraluminal air. We performed colonoscopy and placed the metallic stent. The patient was then improved. After 1 week, the patient underwent elective hand-assisted laparoscopic sigmoidectomy and was discharged 5 days later. Pathological report showed stage IIa sigmoid cancer. The patient had no local recurrence or distant metastasis in 1 year follow up. Conclusion In obstructing colonic patient with pneumatosis intestinalis, nonsurgical treatment by colonic stenting can be used in selected patient as a bridge to definitive surgery. This will result in decreased morbidity and mortality and lower rate of stoma formation.
