Closure of Anastomotic Leaks in the Stomach and Esophagus by Endoscopic Suturing (GASTROSUTURE)

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.
Verified May 2010 by University of Schleswig-Holstein.
Recruitment status was:  Not yet recruiting
Ethicon Endo-Surgery

University of Schleswig-Holstein Identifier:
First received: May 28, 2010
Last updated: June 7, 2010
Last verified: May 2010
Patients with suspected leakage at the specified surgical anastomoses undergo an immediate diagnostic endoscopy as part of current clinical routine. Consenting patients meeting the inclusion criteria will undergo closure of the defect by endoscopic suturing in addition to standard surgical care.

Condition Intervention
Postoperative Anastomosis, Surgical Device: endoscopic suturing

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Safety and Efficacy of Closure of Postoperative Anastomotic Leaks in the Stomach and Esophagus by Endoscopic Suturing: A Prospective Pilot Study

Primary Outcome Measures:
  • Safety [ Time Frame: 2 years ]

    Endpoint to be recorded during hospital stay: Composite serious adverse event endpoint for 30 days after the diagnosis of anastomotic leakage including:

    • Death
    • Injury to vessels through the suture device, leading to bleeding or thrombosis
    • Cardiac tamponade, arrhythmia
    • Pneumothorax
    • Bleeding requiring transfusion
    • possible medium-term complications such as new mediastinal abscess

  • Technical feasibility [ Time Frame: 2 years ]
    Technical success of the anastomotic closure

Secondary Outcome Measures:
  • Time to healing of the anastomotic leak [ Time Frame: 2 years ]
    Scored during the hospital stay until 6 months after the original operation. Patients who die or undergo complete resection of the organ (e. g. esophagectomy with cervical fistula) are scored as "nevel healed" - i.e. censored events. Efficacy statistics need to use local historic controls and literature data. Statistical analysis will be performed using the LogRank test.

  • Long term safety [ Time Frame: 6 months after diagnosis of anastomotic leakage ]

    Long term safety

    • Anastomotic stenosis, as assessed by endoscopy
    • Clinically apparent functional problems (e.g. dysphagia, incontinence)
