Eligibility Criteria
Inclusion
Inclusion Criteria:
The patient must meet all study Inclusion Criteria as outlined below:
Adult males or females, 19-80 years of age, with signed informed consent
Subject whose anastomosis is expected to be located above 4cm from the anus,and at or below 15cm from the anus. (4cm < inclusion target ≤ 15cm from theanus). ③ Patient must meet all other inclusion criteria to be eligible. While notrequired, if one or more of the following six risk factors for postoperativeanastomotic leakage[6,7,8] is true, the patient will be considered a high-risksubject:
Male
Those with a body mass index of 30 or higher
Current smoker
Those who are on medication for diabetes
Those with clinical stage III or higher malignant tumors
Those who received chemo/radiation therapy before surgery ④ Those who are willing and able to participate in this clinical study, provideInformed Consent, and are willing to comply with the study procedures andfollow up evaluations ⑤ Those who have willingness to undertake blood transfusion if required.
Exclusion
Exclusion Criteria:
Patients meeting any of the following Exclusion Criteria will not be eligible to participate in the study:
Women who are pregnant or breastfeeding
Those who receive emergency surgery
A person who is expected to need intensive medical care after the surgery due to aserious medical condition, with one or more of the following seven factors beingtrue:
Patients with abnormal bone marrow function (those with hemoglobin less than 7g/dl, leukocyte count less than 4000/mm3, or platelet count less than 100,000/mm3 even after preoperative corrections)
Patients with severe liver damage or cirrhosis (those whose AST/ALT levels aremore than three times the normal range or those diagnosed with cirrhosis)
Those with abnormal renal function (those who are on hemodialysis or who have ablood creatinine level of 2.0mg/dl or more before the surgery)
Those who have undergone cardiac or cerebrovascular stent procedure within thelast 6 months
Those who have been diagnosed with pulmonary tuberculosis within the last 6months or are undergoing drug treatment for pulmonary tuberculosis
Those who continuously administer steroids of 20mg/day or more within 30 daysbefore the surgery
Patients with ASA (American Society of Anesthesiologists) score of 3 areevaluated by the investigator who determines whether or not patients with ASAscore of 3 should be enrolled from the patient safety standpoint. Patients withASA score higher than 3 are excluded from this study.
Patients who are required to undergo re-intervention to treat the anastomosisfollowing intraoperative positive air leak test (However, patients whounderwent complete reconstruction of the anastomosis in the presence of apositive air test, which therefore has made their risk of leak similar to thosepatients with a negative air leak test.)
Patients who are immune suppressed
Patients with severe diverticulosis
Patients with other colonic wall abnormalities in the likely area of the OuterBalloon and BT BAND application who may be at increased risk for deviceperforation or migration.
- A person who has difficulty in mobility or is unable to communicate in general dueto a psychiatric/neurologic disorder falling under one or more of the following:
Those diagnosed with dementia or Alzheimer's disease.
Those who have been diagnosed with schizophrenia or depression or are takingdrugs due to this.
A person who has been diagnosed with disability due to intellectual disability.
Patients with intestinal perforation, abscess in the pelvis, or severe inflammationin the pelvis.
Those who have a history of undergoing major surgeries (major bowel resection/majorgastrectomy, major hepatectomy) through laparotomy and are likely to have seriousadhesions that may affect this surgery.
A patient who underwent a preoperative chemotherapy, but the anastomosis is expectedto be located very close to the anus or in the anal canal, thus with a very highrisk for complications of the anastomosis, or a patient whom the bowel function isexpected to decrease significantly in the future.
Patients who had pre-operative radiotherapy should be excluded.
Patients with inflammatory bowel diseases such as ulcerative colitis, Crohn'sdisease, intestinal tuberculosis, or autoimmune diseases such as Bechet's disease.
Those who do not consent in writing to the study.
Experienced blood loss (>750 cc) within 6 weeks before randomization.
Transfusion during surgery.
Any new sign of ischemia within 6 weeks before randomization.
Diagnosis of bowel obstruction, bowel strangulation, peritonitis, bowel perforation,intraabdominal infection, ischemic bowel all due to carcinomatosis within 6 weeksbefore randomization.
Known hypersensitivity or allergy to any of the components required for theprocedure.
Exclusion criteria not specified above, but the patient is determined to beunsuitable for participation in this clinical study at the judgment of theresearcher.
