Use of temporary esophageal stent in management of perforations after benign esophageal surgery.
ABSTRACT Successful conservative management in 3 patients with catastrophic postoperative esophageal leak after nonresection surgery is presented. In each case, the placement of removable stent played a significant role. First patient had persistent leak after primary repair of intrathoracic esophageal perforation. The second patient underwent a transthoracic redo Collis-Nissen repair and was subsequently found to have a perforation in the midesophagus. The last patient had a history of recurrent hiatal hernia repair with mesh reinforcement of the hiatus. A perforation resulted from mesh eroding into the esophagus. All the patients had endoscopic placement of removable silicone-covered polyester stent under fluoroscopic guidance. Stent placement was successful in all patients allowing immediate resumption of diet. After stent removal, contrast study showed no leak or stricture. Endoscopic stent therapy is an effective option in the management of postoperative esophageal perforation.

ABSTRACT: Esophageal anastomotic leaks can lead to prolonged hospitalization. In this article we present our experience with the placement of the Polyflex self-expanding plastic stent (Willy Ruesch GMBH, Kernen, Germany) for leak occlusion. Between April 2000 and November 2003, 24 patients were included into this prospective study and underwent Polyflex stent placement for postoperative esophageal anastomotic leaks. The primary operation was esophagectomy in 13 patients, gastrectomy in 7, cardia resection in 2, and other procedures in 2 patients. The median interval between operation and stent placement was 19 days (range, 4 to 65). The effectiveness of leak occlusion was evaluated by water-soluble contrast swallow and the clinical course. In 2 patients stent misplacement produced an enlarged anastomotic dehiscence that necessitated reoperation. Radiologic evaluation was impossible in 4 patients because of their generally restricted condition. Among 18 evaluable patients, leak occlusion was successful with a single stent in 16 patients (89%) based on radiologic evaluation. Immediate oral feeding was well tolerated by these patients. After a median follow-up of 220 days (range, 7 to 1221), 9 cases of late stent dislocation were observed. Stent removal in patients after esophagectomy with gastric pull-up led to dysphagia from anastomotic strictures in 2 patients. Symptomatic strictures did not develop in the 5 evaluable postgastrectomy patients after stent removal. The placement of self-expanding plastic stents is a highly effective treatment for esophageal anastomotic leaks. Because clinically-relevant anastomotic strictures can be expected, we do not recommend stent removal after esophagectomy with gastric pull-up reconstruction.The Annals of thoracic surgery 03/2005; 79(2):398-403; discussion 404. · 3.74 Impact Factor

ABSTRACT: This case report details our experience in the management of an iatrogenic perforation that recurred after two surgical repairs. A self-expanding coated stent was eventually placed to seal the esophageal perforation with significant improvement in the clinical condition of the patient. At 1-year follow-up, the patient is tolerating an oral diet with no evidence of esophageal leak or gastroesophageal reflux. This case report and a literature review suggest that self-expanding coated stents may be a useful salvage option in the management of inveterate nonmalignant esophageal perforations.The Annals of Thoracic Surgery 11/2002; 74(4):1233-5. · 3.45 Impact Factor

ABSTRACT: To evaluate the efficacy of a self-expanding plastic stent in the treatment of thoracic leaks after esophagectomy for cancer. Anastomotic leaks are a major cause of morbidity and mortality after esophageal resection. Treatment options range from aggressive surgery to conservative management, but there remains much controversy on the best treatment. Over a 6-year period (1998-2003), esophagogastric leaks were observed in 19 of 204 patients (9.3%) after esophagectomy. Between 1998 and 2000, anastomotic leaks were managed by reexploration (n = 7) or by conservative treatment (n = 3). Since 2001, insertion of self-expanding plastic stents was performed for all anastomotic leaks (n = 9). The short-term efficacy and long-term outcome of both treatments were analyzed. Self-expanding plastic stents were successfully placed in all patients without procedure-related morbidity. Immediate leak occlusion was obtained in 8 of 9 patients. The mean healing time (time to stent removal) was 29 days. Compared with the conventional treatment group, patients who were treated with stents had earlier oral intake (11 days versus 23 days), a less extensive intensive care course (25 days versus 47 days), and shorter hospital stay (35 days versus 57 days). In-hospital mortality was 0% (0 of 9 patients) in the stent group and 20% (2 of 10 patients) in the other group. After a mean follow-up of 12 months, none of the patients developed a stricture after stenting, but a stricture occurred in 1 patient after conservative treatment. Self-expanding plastic stents can reduce leak-related morbidity and mortality after esophagectomy and may be considered a cost-effective treatment alternative.Annals of Surgery 12/2004; 240(5):801-7. · 6.33 Impact Factor
