Filter by:This trial aims to assess safety and efficacy of three-row circular staplers compared to two-row surgical stapllers in short-term and long-term perspective in patients with rectal cancer undergoing low anterior resection with stapled colorectal anastomosis. All the patients will undergo a low anterior resection. In a half of patients a colorectal anastomosis will be created with a three-row surgical circular stapler. In another half of patients a colorectal anastomosis will be created with a two-row surgical circular stapler.
A leak from a colorectal anastomosis is a post-operative complication surgeons fear the most, following colonic resection. Over the years, there have been multiple suggestions for intraoperative tests for the integrity of the colorectal anastomosis. Two of the most common tests that are performed routinely are: 1. Air tight leak test - filling the pelvis with saline and insufflating air trans anal - looking for air bubbles in the saline filled pelvis. 2. Injecting diluted dye (methylene blue) trans anal, and looking for blue dye stains on gauze pads covering the outer side of anastomosis. The aim of the study is to compare the two methods, and to assess if there is a superior method. A secondary aim is to establish standards to perform the test, mainly to assess the appropriate pressure to apply on the anastomosis. In this prospective study patients scheduled to undergo colonic resection of their distal part of the colon/ rectum with colorectal anastomosis, will have both testing methods performed sequentially and will be followed post-operative to assess the yield and sensitivity of the testing methods.
During the last few years, the laparoscopic right colectomy with intracorporeal ileocolic anastomosis (IIA) has been proposed as an alternative to laparoscopic right colectomy with extracorporeal ileocolic anastomosis (EIA) for the treatment of right colon tumors. However, the level of evidence coming from the currently available literature is low, based on the results of a few small and heterogeneous retrospective non-randomized studies. A randomised controlled trial is warranted to challenge these two procedures. The aim of this randomized controlled trial is to assess the outcomes after IIA or EIA after laparoscopic right colectomy for right colon tumors.
The purpose of this study is to evaluate the efficacy of end-to-side anastomosis after laparoscopic right hemicolectomy compared with that of side-to-side anastomosis. The investigators hypothesize that the end-to-side anastomosis may be associated with superior recovery compared with side-to-side anastomosis after laparoscopic right hemicolectomy under enhanced recovery program. The primary endpoint is the cumulative recovery rate, consisting of the recovery time of diet, pain, ambulation, and afebrile status.
Colorectal surgery is highly associated with septic complications, therefore, multiple approaches have been used to reduce this complications, one of the most used is mechanical bowel preparation. Lately multiple studies have suggested that mechanical bowel preparation might not be necessary.
Traditionally the watertightness of urethrovesical anastomosis after robotic radical prostatectomy is controlled by cystogram. However, clinical observations and one previous study showed that patients with anastomotic leakage have red coloured urine. If the investigators can verify this finding, the most of the cystograms can be avoided. In this study the investigators estimate urine colour after cystogram and take a picture from urine collecting pag. Later on the pictures are digitally analyzed and compared to cystogram finding.
- To date, Roux-en-Y esophagojejunostomy transabdominal extracorporeally by circular stapler was the most common used method during laparoscopy-assisted total gastrectomy for gastric cancer, even though it was not totally laparoscopic surgery in which intracorporeal anastomosis should be performed. - To gain potential clinical benefits from a smaller length of minilaparotomy and an easier anastomosis technique than extracorporeal anastomosis, intracorporeal Roux-en-Y anastomosis using a transorally inserted anvil (OrVil™) during totally laparoscopic total gastrectomy was adopted by experienced surgeons recently. - However, the safety of intracorporeal Roux-en-Y esophagojejunostomy using a transorally inserted anvil (OrVil™) has not yet been evaluated. Thus, the study comparing the safety of intracorporeal versus extracorporeal Roux-en-Y esophagojejunostomy by circular stapler based on a well designed randomized controlled trial is needed.
