Massive esophageal perforation managed with a covered esophageal stent.

Esophageal stents have become an emergent, effective treatment for esophageal perforation, whether spontaneous or iatrogenic. We report a case of iatrogenic perforation secondary to malposition of a Sengstaken-Blakemore balloon (SBB), which was inserted to control acute variceal bleeding. SBB currently has very limited indications in the management of variceal bleeding given the ongoing advances in endoscopic techniques, and its use is not exempt from complications such as the one reported herein.

Endoscopic removal of an embedded uncovered biliary self-expandable metal stent with a mechanichal lithotriptor.

Biliary fully-covered self-expandable metal stents (FCSEMS) can be used for benign conditions since they can be removed. Uncovered SEMS (uSEMS) are employed for malignant biliary obstruction and are intended to be permanent. Furthermore, they are almost impossible to remove because they become embedded in the bile duct. We present a technique for uSEMS removal in a patient in whom a biliary uSEMS had been inserted for two years. Biliary obstruction due pancreatic cancer was misdiagnosed. Finally an IgG4 related-disease (autoimmune pancreatitis) was identified.

A giant abdominal collection: when things are not what they seem.

Endoscopic ultrasound-guided transluminal drainage (EUS-TD) has become the standard of care for the treatment of peripancreatic fluid collections (PFCs). New lumen-apposing metal stents (LAMS) have facilitated the drainage technique . However, this fact should not cloud our view when planning a EUS-TD, as occasionally things are not what they seem.

EUS-guided coil versus cyanoacrylate therapy for the treatment of gastric varices: a multicenter study (with videos).

BACKGROUND: Therapy of gastric varices (GV) is still challenging. Cyanoacrylate (CYA) injection is the recommended treatment for bleeding GV, but has a known adverse event rate, which could be reduced if EUS is used for guidance. Otherwise, EUS-guided coil application (ECA) may be an alternative. OBJECTIVES: To compare CYA and ECA embolization of feeding GV for feasibility, safety, and applicability. DESIGN: Retrospective analysis of a prospectively maintained database. SETTING: Multicenter study, tertiary referral centers. PATIENTS AND INTERVENTIONS: Thirty consecutive patients with localized GV who received either CYA injection or ECA were included with follow-up for 6 months after treatment. RESULTS: There were 11 patients in the coil group and 19 patients in the CYA group. The GV obliteration rate was 94.7% CYA versus 90.9% ECA; mean number of endoscopy sessions was 1.4 ± 0.1 (range 1-3). Adverse events occurred in 12 of 30 patients (40%) (CYA, 11/19 [57.9%]; ECA, 1/11 [9.1%]; P < .01); only 3 were symptomatic, and an additional 9 (CYA group) had glue embolism on a CT scan but was asymptomatic. No further adverse events occurred during follow-up. Six patients (20%) died unrelated to the procedures or bleeding. LIMITATIONS: Nonrandomized; EUS expertise necessary. CONCLUSIONS: EUS-guided therapy for GV by using CYA or ECA is effective in localized GV. ECA required fewer endoscopies and tended to have fewer adverse events compared with CYA injection. Larger comparative studies are needed to prove these data.

Intragastric endoscopic assisted single incision surgery for gastric leiomyoma of the esophagogastric junction.

Single port laparoscopic surgery is becoming an alternative to conventional laparoscopic surgery as a new approach where all the conventional ports are gathered in just one multichannel port through only one incision. Appling this technical development, we have developed a new technique based on an intragastric approach using a single port device assisted by endoscopy (I-EASI: intragastric endoscopic assisted single incision surgery) in order to remove benign gastric lesions and GIST tumors placed in the posterior wall of the stomach or close to the esophagogastric junction or the gastroduodenal junction. We present a patient with a submucosal gastric tumor placed near the esophagogastric junction removed with this new approach.

EUS-guided injection of cyanoacrylate in perforating feeding veins in gastric varices: results in 5 cases.

BACKGROUND: Bleeding from gastric varices can be challenging because of its high mortality and recurrent bleeding rates. Endoscopic therapy with tissue adhesives can control acute hemorrhage, but recurrent bleeding could appear if obliteration is not achieved, and endoscopic vision could be troublesome in the case of massive hemorrhage. The glue injected could be responsible for embolic phenomena and local complications. EUS has proved useful in minimizing the risk of recurrent bleeding from gastric varices, accurately showing if they are obturated or not. The presence of perforating veins detected by EUS has been reported as a risk factor for recurrent bleeding from esophageal varices. OBJECTIVE: To assess the efficacy of EUS-guided cyanoacrylate injection in gastric varices at the entrance of the perforating veins to obtain variceal obturation. DESIGN: Open-basis case series study. SETTING: Tertiary care, academic medical center, Seville, Spain. PATIENTS: Five consecutive patients with gastric varices were enrolled from May 2005 through May 2006. INTERVENTIONS: We injected cyanoacrylate-lipiodol in gastric varices with 22-gauge needles by EUS guidance. MAIN OUTCOME MEASUREMENTS: To analyze the obliteration of gastric varices, the recurrent bleeding rate, and safety of EUS-guided cyanoacrylate-lipiodol injection. RESULTS: EUS-guided injection of the perforating veins by using cyanoacrylate-lipiodol was successful in eradicating gastric varices in the 5 patients treated, without recurrent bleeding or other complications during the study follow-up. LIMITATION: This is a single-center nonrandomized study. CONCLUSIONS: EUS-guided injection of cyanoacrylate at the level of the perforating veins in the treatment of gastric varices seems to be a safe, efficient, and accurate approach. Further controlled studies are warranted.
