NCT ID: NCT06229197 Not yet recruiting - Gastric Cancer Clinical Trials

Billroth II With Braun Anastomosis After Radical Distal Gastrectomy for Gastric Cancer

Start date: February 1, 2024
Phase: N/A
Study type: Interventional

The primary aim of this trial is to rigorously evaluate the comparative benefits and potential risks associated with Billroth II reconstruction with Braun anastomosis versus Billroth II reconstruction alone following distal gastrectomy with D2 lymphadenectomy in patients diagnosed with gastric cancer. This assessment focuses on delineating the therapeutic efficacy, safety profile, and overall clinical outcomes of these two surgical approaches in treating this condition.

NCT ID: NCT06222645 Recruiting - Perfusion Clinical Trials

PPG vs. ICG in Gastrointestinal Resections

Start date: November 1, 2023
Phase: N/A
Study type: Interventional

In this study, gastrointestinal anastomoses are examined with imaging Photoplethysmography and after this the investigators use the Standard Routine ICG-Imaging. At the end, both methods will be compared.

NCT ID: NCT06146023 Completed - Robotic Surgery Clinical Trials

Performance of Robotic Microsurgery Systems

Start date: October 1, 2022
Phase: N/A
Study type: Interventional

The goal of this preclinical trial is to learn about the benefits and limitations of novel robotic devices for microsurgery, based on different levels of microsurgical experience. The main questions it aims to answer are: Is robot-assisted microsurgery faster, better and more ergonomic than conventional microsurgery in a preclinical standardized setting? Participants will perform microvascular anastomoses on 1.0-mm-diameter artificial silicone vessels using a conventional manual approach versus a novel robot-assisted approach. Researchers will compare the performance of novices, advanced participants and experts to evaluate the role of microsurgical experience when learning the new technique.

NCT ID: NCT06062225 Not yet recruiting - Clinical trials for Postoperative Complications

Protocol for Comparing the Efficacy of Three Reconstruction Methods of the Digestive Tract After Proximal Gastrectomy

Start date: October 2023
Phase: N/A
Study type: Interventional

The efficacy of three different reconstruction methods after proximal gastrectomy will be investigated in this study through a prospective, multicenter, randomized controlled trial.

NCT ID: NCT05879172 Completed - Rectal Cancer Clinical Trials

Electric Tubular Anastomosis in Rectal Cancer

Start date: July 1, 2021
Phase: N/A
Study type: Interventional

Compared with traditional manual suturing, mechanical anastomosis can reduce the error caused by human factors. The electric anastomotic device can improve the automation and accuracy of anastomosis, reduce the requirements for doctors' operation, and establish a more standardized usage specification, thereby reducing the surgical complication rate and improving the quality of anastomosis. The clinical study of electric tubular anastomotic device adopts a multicenter, randomized, parallel controlled non-inferior study design, and randomly groups according to the 1:1 ratio to evaluate the clinical effectiveness and safety of electric tubular anastomotic device compared with conventional manual device.

NCT ID: NCT05829213 Recruiting - Anastomosis Clinical Trials

A Modified Esophagogastric Reconstruction Method After Laparoscopic Proximal Gastrectomy

Start date: November 1, 2021
Phase: N/A
Study type: Interventional

The double-flap technique (DFT) is an effective digestive tract reconstruction method after proximal gastrectomy (PG) to reduce the incidence of postoperative reflux esophagitis. But its clinical application is restricted due to the technical complexity. Our surgical team devise a modified esophagogastric reconstructive method which we term the "arch-bridge-type" reconstruction based on the principle of DFT. The aim of this single-arm prospective study is to assess the safety and feasibility of the "arch-bridge-type" reconstruction after PG.

NCT ID: NCT05753709 Completed - Ileus Clinical Trials

Conventional Hand Sewn End-To-End Anastomosis Versus Side-To-Side Anastomosis for Stoma Reversal: A Prospective Study

Start date: January 1, 2022
Phase: N/A
Study type: Interventional

The goal of this clinical trial is to compare approaches to enterostomy reversal by hand-sewn end-to-end anastomosis versus side-to-side anastomosis (sub-divided into hand-sewn side-to-side anastomosis and stapled side-to-side anastomosis). The main question it aims to answer is: • If either of the approaches are better than the other with respect to success rates, efficacy, post-operative complications and overall morbidity. Participants admitted for stoma reversal will be divided into two groups: 1. EE: Conventional Hand-sewn end-to-end anastomosis, and 2. SS: Side-to-side anastomosis, which will be further divided into 2 sub-groups: 1. HSSA: Hand-sewn side-to-side anastomosis 2. SSSA: Stapled side-to-side anastomosis Researchers will compare the EE group to SS group overall, and a second comparison will be made between EE, HSSA and SSSA groups, to see: 1. Rates of major post-operative complications 2. Rates of short-term complications (within 30 days of surgery) 3. Rates of re-operation 4. Post-operative length of stay in the hospital

NCT ID: NCT05655975 Not yet recruiting - Obesity, Morbid Clinical Trials

Regain Rate According to gj Anastomosis Size in Gastric Bypass

Start date: December 15, 2022
Phase: N/A
Study type: Interventional

Obesity has become an important medical and social problem in western countries today. Roux-en-Y gastric bypass (LRYGB) is the most commonly performed surgery for the treatment of morbid obesity in the United States. Recently, there has been a steady increase in the number of surgeons performing bariatric surgery. In 2008, approximately 344,000 bariatric procedures were performed worldwide, of which 220,000 were performed in the United States and Canada. Most of these surgeries were laparoscopic gastric bypass procedures. There are many technical variations in the performance of the Roux-en-Y gastric bypass, especially when the approach is laparoscopic. Three techniques are commonly used when creating a gastrojejunostomy (GJ): hand-sewn, linear-staple, and circular-staple approaches. The effect of larger-caliber gastrojejunostomy on long-term weight loss is worrisome. Numerous recent reports describe the relationship between gastrojejunostomy enlargement and weight gain after gastric bypass, suggesting that this is a potentially valid concern. In this study, we aim to determine the effect of this potential GJ enlargement on weight loss.

NCT ID: NCT05180565 Completed - Colorectal Cancer Clinical Trials
