Trial summary
The present randomized study is designed to compare the quality of life between the patients undergoing laparoscopy-assisted and totally laparoscopic distal gastrectomy for gastric cancer, and therefore to evaluate the superiority of totally laparoscopic distal gastrectomy to laparoscopy-assisted distal gastrectomy.

About this study
Official title: A Multicenter Randomized Controlled Trial Comparing the Quality of Life Between Laparoscopy-assisted Distal Gastrectomy and Totally Laparoscopic Distal Gastrectomy for Gastric cancer_KLASS 07 (CKLASS01)(Korea-China Collaborated Study)
The present randomized study is designed to compare the quality of life between the patients undergoing laparoscopy-assisted and totally laparoscopic distal gastrectomy for gastric cancer, and therefore to evaluate the superiority of totally laparoscopic distal gastrectomy to laparoscopy-assisted distal gastrectomy.
Read the detailed description
The primary endpoint of this trial is the early postoperative morbidity, that is defined as complications that occur within 30 days after surgery.
Early postoperative morbidity is classified as follows:
(1) wound morbidity (2) surgical site morbidity: anastomosis bleeding or leakage, duodenal stump leakage, postoperative bleeding, afferent loop or efferent loop obstruction, etc.; (3) lung morbidity: atelectasis, pleural effusion, empyema, pneumothorax, etc.; (4) intestinal obstruction morbidity (5) urinary tract morbidity (6) intra-abadominal abscess (7) postoperative pancreatitis (8) pancreatic fistula (9) intestinal fistula 10) others: lymphorrhea, diarrhea, etc.
The secondary end point is the questionnaire score regarding QOL. This is assessed by the Korean versions of the EORTC QLQ-C30 (version 3.0) and STO22 questionnaires.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
TLDG armProcedure or surgery
After lymphadenectomy, gastrectomy and reconstruction procedure are performed intracorporeally without mini-laparotomy(TLDG)

After lymphadenectomy, gastrectomy and reconstruction procedure are performed extracorporeally through mini-laparotomy(LADG)

Questions about this trial
What is this clinical trial studying?
A study testing TLDG arm and LADG arm in people with Quality of Life and Gastric Cancer, run by Korea University Anam Hospital at 1 site in South Korea.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 13 Apr 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Postoperative 30-day morbidity rate (time frame: Postoperative 30-day). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03393182, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Apr 2022.
