Conditions

Anastomotic Leaks, Hartmanns Stump Leakage

Brief summary

This study is intended to evaluate the safety and effectiveness of Sponge-based Endoscopic Vacuum Therapy (EVT) using Endo-SPONGE for the treatment of Anastomotic Leaks (AL) or Hartmann's stump leakages following colorectal surgery in a prospective multi-center study.

Interventions

DEVICEEndo-SPONGE

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

Inclusion criteria

* 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.

Exclusion criteria

* 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.

Design outcomes

Primary

MeasureTime frameDescription
Serious Adverse EventsDay 0 Study Procedure to end of study; up to 6 monthsThe 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.
Clinical SuccessDay 0 Study Procedure to the last study device removal; up to 3 monthsThe 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.

Secondary

MeasureTime frameDescription
Technical SuccessDay 0 Study Procedure to the last study device exchange; up to 3 monthsDefined as the ability to deploy the Endo-SPONGE in the intended location. This will be calculated for study procedure and every Endo-SPONGE Exchange that is attempted.
Closure TimeDay 0 Study Procedure to the last study device removal; up to 3 monthsTime to colorectal anastomotic or Hartmann's stump leak closure.
Rate of ReinterventionsFrom last study device removal to end of study; 3 monthsRate of Reinterventions after closure of the anastomotic or Hartmann's stump leak.
Time to Additional InterventionDay 0 Study Procedure to the last study device removal; up to 3 monthsTime to additional intervention, if Endo-SPONGE treatment is insufficient.
Leak RecurrenceFrom last study device removal to end of study; 3 monthsLeak recurrence within 3 months following completion of Endo-SPONGE therapy.
Endo-SPONGE ExchangesDay 0 Study Procedure to last study device removal; up to 3 monthsNumber of Endo-SPONGE exchanges needed to reach clinical success.
Length of HospitalizationDay 0 Study Procedure to end of study; up to 6 monthsLength of Hospitalization.
Mortality RateDay 0 Study Procedure to end of study; up to 6 monthsMortality rate through 3-month follow-up.
