Outcome Measures

Primary Outcomes (2)

  • Serious Adverse Events

    The proportion of subjects with one or more study device or endoscopic or study procedure-related Serious Adverse Events (SAEs) occurring up to 3 months after the last study device removal.

    Day 0 Study Procedure to end of study; up to 6 months

  • Clinical Success

    The proportion of subjects that demonstrate clinical success, which is defined as closure of the anastomotic or Hartmann's stump leak, confirmed via endoscopy or contrast-enhanced computed tomography imaging within 3 months after the study procedure without the need for an additional endoscopic or surgical intervention.

    Day 0 Study Procedure to the last study device removal; up to 3 months

Secondary Outcomes (8)

  • Technical Success

    Day 0 Study Procedure to the last study device exchange; up to 3 months

  • Closure Time

    Day 0 Study Procedure to the last study device removal; up to 3 months

  • Rate of Reinterventions

    From last study device removal to end of study; 3 months

  • Time to Additional Intervention

    Day 0 Study Procedure to the last study device removal; up to 3 months

  • Leak Recurrence

    From last study device removal to end of study; 3 months

  • +3 more secondary outcomes

Study Arms (1)

Endoscopic Vacuum Therapy (EVT) Device

EXPERIMENTAL
Device: Endo-SPONGE

Interventions

The intervention involves the placement of an Endo-SPONGE in the leakage cavity, and applying suction to facilitate drainage.

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Confirmed grade B anastomotic leak as per the ISGRC (International Study Group of Rectal Cancer) grading system after colorectal surgery.
  • Subject is eligible for endoscopic intervention.
  • Subject has a transmural defect of at least 2 cm in diameter following colorectal surgery in the lower pelvic area.
  • Subject has an anastomotic or Hartmann's stump leak located within an extraperitoneal cavity.
  • Subject has pre-existing diverting ostomy or an ostomy created prior to the first Endo-SPONGE placement.
  • Subject understands the trial requirements and is willing and able to comply with the study procedures, all protocol-required follow up evaluations and provide written informed consent to participate in the study.
  • Investigator decision that EVT is the most suitable treatment of the available treatment options.

You may not qualify if:

  • Subject is under 18 years of age.
  • Potentially vulnerable subject, including, but not limited to pregnant women.
  • Subject has undergone EVT or other similar interventions for the current colorectal indication.
  • Subject had colorectal surgery more than 60 days prior to the planned study procedure.
  • Subject has any necrotic tissue that would require endoscopic debridement prior to Endo-SPONGE placement.
  • Subject has known contraindication for EVT as per the IB.
  • Subject is currently enrolled in another investigational study that would directly interfere with the current study, without prior written approval from the sponsor.
