Endoluminal vacuum therapy for anastomotic insufficiency after gastrectomy

Inhaltsübersicht

The reported incidence of anastomotic leaks is between 5 % and 25 %. Depending on the position and dimensions of the leaks, they are associated with a mortality of up to 60 % [1]. So far endoluminal vacuum therapy has mainly been used for treatment of anastomotic insufficiencies of the rectum [2]. Its use in the esophagus was first reported in 2007 and in only three more cases since then [3] [4] [5].

Here we report a case of a 67-year-old man who developed an anastomotic insufficiency following gastrectomy. Postoperatively, the patient presented a severely septic clinical picture and therefore surgical revision was impossible. He was ventilated and given antibiotics. On endoscopic examination 7 days after gastrectomy, a 1-cm leak covering 30 % of the anastomotic circumference was noted, with an abdominal fistula. We started endoluminal vacuum therapy by endoscopic insertion of the Endo-SPONGE system (B. Braun Melsungen AG, Melsungen, Germany; [Fig. 1]) into the esophagus. The Endo-SPONGE is an open-pored polyurethane sponge. Before insertion, we adjusted its size according to the local topography of the esophagus ([Fig. 2]). The sponge was placed via an overtube into the region of the anastomotic insufficiency at the distal end of the esophagus ([Fig. 3]). The suction tube was extended with a nasogastric tube and secretions were continuously evacuated with a suction of 13.3 kPa. Following daily suction of 200 – 400 mL of secretions, the patient's condition improved remarkably within a few days. We carried out the procedure for a total of 18 days, changing the Endo-SPONGE system every second or third day. The abdominal fistula underwent marked reduction and the anastomotic area epithelialized ([Fig. 4]). The leak was no longer detectable on radiographs and the patient recovered completely.

In summary, endoluminal vacuum therapy offers an alternative method for the treatment of complicated anastomotic insufficiency following esophageal or gastric surgery.
