Endoscopic Management of Esophageal Anastomotic Leaks After Surgery for Malignant Disease.

BACKGROUND

Esophageal anastomotic leaks after cancer surgery remain a major cause of morbidity and mortality. Endoscopic interventions, including covered metal stents (cSEMS), clips, and direct percutaneous endoscopic jejunostomy (dPEJ) tubes are increasingly used despite limited published data regarding their utility in this setting. This study aimed to determine the efficacy and safety of a multimodality endoscopic approach to anastomotic leak management after operation for esophageal or gastric cancer.

METHODS

We performed a retrospective review of prospectively maintained databases of gastric and esophageal operations at our hospital between January 2003 and December 2012. Included patients had an operation for esophageal or gastric cancer, demonstrated evidence of an anastomotic leak at the esophageal anastomosis, and underwent attempted endoscopic therapy. Healing was defined as clinical and radiographic leak resolution.

RESULTS

Forty-nine patients with leaks underwent endoscopic management. Of the 49 patients, 31 (63%) received cSEMS, 40 (82%) had dPEJ tubes inserted, and 3 (6%) received clips. Twenty-three (47%) patients underwent a combined approach. Overall, 88% of patients achieved healing in a median of 83 days. Twenty-two of 23 patients (96%) who underwent a multimodality endoscopic approach healed. Only 1 patient had a major complication associated with stent erosion into the pulmonary artery, which was successfully treated with operative repair.

CONCLUSIONS

Esophageal anastomotic leaks after esophageal and gastric cancer operations can be managed successfully and safely with endoscopic therapy. Combining cSEMS for leak control and dPEJ tube placement for nutritional support was highly effective in achieving healing, without the need for surgical repair.
