RESUMO

BACKGROUND: Chronic leaks after laparoscopic sleeve gastrectomy (LSG) are often difficult to treat by endoscopy metallic stent. Septotomy has been indicated as an effective procedure, but the technical aspects have not been detailed in previous publications (Campos JM, Siqueira LT, Ferraz AA, et al., J Am Coll Surg 204(4):711, 2007; Baretta G, Campos J, Correia S, et al., Surg Endosc 29(7):1714-20, 2015; Campos JM, Pereira EF, Evangelista LF, et al., Obes Surg 21(10):1520-9, 2011). We herein present a video (6 min) demonstrating the maneuver principles of this technique, showing it as a safe and feasible approach. METHODS: A 32-year-old male, with BMI 43.4 kg/m(2), underwent LSG. On the tenth POD, he presented with a leak and initially was managed with the following approach: laparoscopic exploration, drainage, endoclips, and 20-mm balloon dilation. However, the leak remained for a period of 6 months. On the endoscopy, a septum was identified between the leak site and gastric pouch, so it was decided to "reshape" this area by septotomy. Septotomy procedure: Sequential incisions were performed using argon plasma coagulation (APC) with 2.5 flow and 50 W (WEM, SP, Brazil) over the septum in order to allow communication between the perigastric cavity (leak site) and the gastric lumen. The principles below must be followed: (1) Scope position: the endoscopist's left hand holds the control body of the gastroscope while the right hand holds the insertion tube; the APC catheter has no need to be fixed. This avoids movements and unprogrammed maneuvers. (2) Before cutting, the septum is placed in the six o'clock position on the endoscopic view, by rotating the gastroscope. (3) The septum is sectioned until the bottom of the perigastric cavity (leak site). (4) That section is made towards the staple line. (5) Just after the septotomy, a Savory-Gilliard guidewire (Cook Medical, Indiana, USA) through the scope must be inserted until the duodenum, followed by 30-mm balloon (Rigiflex®, Boston Scientific, MA, USA) insertion. The balloon catheter must be firmly held during gradual inflation (maximum 10 psi) to avoid slippage and laceration. This allows increasing the gastric lumen. (6) Septotomy by electrocautery with a needle knife (Boston Scientific, MA, USA) can be made when an intensive fibrotic septum is present; bleeding is rare in this case. In this case, the endoclip previously used was removed from the septum with forceps to avoid heat transmission. Small staples visualized in the fistula orifice were not completely removed due to technical difficulties and friable tissue. RESULTS: Two sessions were performed in 15 days, resulting in leak closure. The patient was submitted to radiological control 1 week after the second session, which revealed fistula healing, without gastric stenosis. The nasoduodenal feeding tube remained for 7 days, when the patient started oral diet. This patient was followed for 18 months without recurrence. CONCLUSIONS: Septotomy and balloon dilation were initially performed on a difficult-to-treat chronic fistula after gastric bypass and named before as stricturotomy (Campos JM, Siqueira LT, Ferraz AA, et al., J Am Coll Surg 204(4):711, 2007). This procedure allows internal drainage of the fistula and deviates oral intake to the pouch. In addition, achalasia balloon dilation treats strictures and axis deviation of the gastric chamber, promoting reduction of the intragastric pressure. Septotomy and balloon dilation are technically feasible and might be useful in selected cases for closure of chronic leaks after LSG.

RESUMO

AIM: To evaluate the results of duodenal stenting for palliation of gastroduodenal malignant obstruction by using a gastric outlet obstruction score (GOOS). METHODS: A prospective, non-randomized study was performed at a tertiary center between August 2005 and April 2010. Patients were eligible if they had malignant gastric outlet obstruction (GOO) and were not candidates for surgical treatment. Medical history and patient demographics were collected at baseline. Scheduled interviews were made on the day of the procedure and 15, 30, 90 and 180 d later or unscheduled as necessary. RESULTS: Fifteen patients (6 male, 9 female; median age 61 years) with GOO who had undergone duodenal stenting were evaluated. Ten patients had metastasis at baseline (66.6%) and 14 were unable to accept oral intake (93.33%), including 7 patients who were using a feeding tube. Laboratory data showed biliary obstruction in eight cases (53.33%); all were submitted to biliary drainage. Two patients developed obstructive symptoms due to tumor ingrowth after 30 d and another due to tumor overgrowth after 180 d. Two cases of stent migration occurred. A good response to treatment was observed, with a mean time of approximately 1 d (19 h) until toleration of a liquid diet and slightly more than 2 d for both soft solids (51 h) and a solid food/normal diet (55 h). The mean time to first failure to maintain liquid intake (GOOS ≥ 1) was 93 d. During follow-up, the mean time to first failure to maintain the previously achieved GOOS of 2-3 (solid/semi-solid food), considered technical failure, was 71 d. On the basis of oral intake a GOOS is defined: 0 for no oral intake; 1 for liquids only; 2 for soft solids only; 3 for low-residue or full diet. CONCLUSION: Enteral stenting to alleviate gastroduodenal malignant obstruction improves quality of life in patients with limited life expectancy, which can be evaluated by using a GOO scoring system.

RESUMO

CONTEXT: To demonstrate a comprehensive review of published articles regarding EUS-guided biliary drainage. METHODS: Review of studies regarding EUS-guided biliary drainage including case reports, case series and previous reviews. RESULTS: EUS-guided hepaticogastrostomy, choledochoduodenostomy and choledochoantrostomy are advanced procedures on biliary and pancreatic endoscopy and together make up the echo-guided biliary drainage. Hepaticogastrostomy is indicated in cases of hilar obstruction, while the procedure of choice is choledochoduodenostomy in distal lesions. Both procedures must be done only after unsuccessful ERCP. The indication of these procedures must be made under a multidisciplinary view while sharing information with the patient or legal guardian. CONCLUSION: Hepaticogastrostomy and choledochoduodenostomy are feasible when performed by endoscopists with expertise in biliopancreatic endoscopy and advanced echo-endoscopy and should be performed currently under rigorous protocol in educational institutions.

RESUMO

CONTEXT: To demonstrate an EUS-guided biliary drainage in patient with gastrointestinal tract modified surgically. CASE REPORT: An EUS guided access to the left intra hepatic duct, followed by an antegrade passage of a partially self-expandable metal stent that was removed by using an enteroscope, in one patient with hepatico-jejunal anastomosis. There were no early or delayed complications and the procedure was effective in relieving jaundice until the self-expandable metal stent was removed, 3 months later. A cholangiogram was obtained via enteroscopy, after removal of self-expandable metal stent, and found to be normal. The patient had an uneventful evaluation afterwards. CONCLUSION: The indication of these procedures must be made under a multidisciplinary view while sharing information with the patient or legal guardian. EUS-guided biliary drainage is feasible when performed by professionals with expertise in biliopancreatic endoscopy and advanced echo-endoscopy and should be performed currently under rigorous protocol in educational institutions.
