A 57-year-old male was diagnosed with a sigmoid colon perforation by an adenocarcinoma with synchronous liver metastasis (pT4aN0M1) and submitted to a Hartmann's operation with hepatic metastasectomy. After chemotherapy has been finished, the patient underwent intestinal transit reconstruction, and a colorectal anastomosis with protective ileostomy was performed. In the postoperative period, complete anastomotic stenosis developed, which was confirmed in sigmoidoscopy and computed tomography scan [Figure 1]. Leakage and fistulization were ruled out, and endoscopic treatment was scheduled after gastroenterology consultation.{Figure 1}

A total colonoscopy was performed with anterograde progression through the ileostomy until the stricture. Mucus plugs made scope progression difficult. Gastrografin was injected to fill the lumen and to optimize ultrasound viewing. Using a forward-viewing linear echoendoscope introduced through the anus, EUS guided puncture of the upstream colon loop was accomplished with a 19G needle (EchoTip ProCore®, Cook Medical®, Ireland) that allowed further passage of the 0.035 guidewire under endoscopic control. A 6F cystotome (Endoflex®, Germany) and Through-The-Scope balloons (8 mm + 10 mm) were used for tract dilation. A lumen-apposing metal stent (LAMS) with 16 mm × 20 mm (SPAXUS®) was introduced through the fistula and deployed under endoscopic and fluoroscopic guidance. After deployment, the distal flare was placed juxta-anastomotic, being easily repositioned using a foreign body forceps. Contrast and mucus drainage confirmed lumen patency at the end of the procedure. In the control sigmoidoscopy performed after 1 week, LAMS was perpendicular to the lumen being removed. Complete recanalization of the anastomosis was achieved without extraluminal leakage [Figure 2].{Figure 2}

Anastomotic strictures usually occur after colorectal surgery. Complete lumen obstruction is uncommon and surgical reintervention may be indicated due to inability to pass conventional dilation systems and endoscopic stents.[1] Few cases of EUS-guided recanalization of complete anastomotic strictures using LAMS were described in anedoctical reports with favorable outcomes.[2],[3] The present report highlights the effectiveness of this minimally invasive approach and its applicability in clinical practice.
