In this video, Dr. Roel Hompes speaks about the construction of the ideal ileal pouch. He defends that the transanal approach is the logical next step after the transabdominal subtotal colectomy, since it allows for a total proctectomy under direct vision and facilitates the pouch construction and anastomosis. He also presents the first data from a collaborative study between centers all over Europe that show positive results for the transanal approach.
In this video in the Ileal Pouch Series, Dr. Kienle talks about the disadvantages of TaTME.
Restorative proctocolectomy is indicated for treatment of inflammatory bowel diseases such as ulcerative colitis or in familial polyposis.
Only around 20% of cases require an oncological procedure, performing a total mesolectal excision.
In this video Dr. Kienle presents the disadvantages of TaTME-Pouch from his point of view.
There is no hard evidence on nerve damage, functional impact, or better anastomotic results, for taTME versus lapTME.
According to Dr. Kienle, making a purse-string to create an anastomosis is more difficult because if the purse-string is not tight, the risk of tissue and organ injury is higher due to impaired vision.
Dr. Kienle concludes that using taTME for a restorative proctocolectomy has no proven advantages, may be harmful and more expensive, but it is important to investigate further.
In this talk, Baljit Singh speaks about the recorded data about pouches from 2012 to 2017.
Pouch surgery is not a common surgery within the scope of colorectal surgery. Of the approximately 400 surgeons who have ever performed this surgery, only 26 have performed more than 15 operations.
The majority of them, 126, have only performed one pouch surgery.
The ratio of complications and readmission is high in this surgery.
The most common diagnosis of patients having primary ileoanal pouch surgery is ulcerative colitis and familial adenomatous polyposis.
In recent years there has been a variation in the use of the different Pouch designs. Currently almost 100% of the pouch made are J-Pouch.
Roel Hompes from the Academic Medical Center of Amsterdam talks about the lessons learned from the international TaTME registry for benign disease. After making a comprehensive review of all the developing phases of TaTME, Dr. Hompes explain how the international registry was designed as well as which were the initial variables that were studied. TaTME cases for benign disease represent less than 10% of all the registered data with high variability of indications. Technical variations when compared to TaTME for cancer, learning curve issues, postoperative outcome are discussed. Some of the current drawbacks and areas for improvement of the TaTME benign disease registry are also reviewed.
In this EHTG/ESCP lecture Professor Antonio Spinelli from Humanitas Research Hospital in Milano explains the pros and cons of performing a “near to TME” dissection when performing a pouch for FAP. Despite the fact TME dissection has been considered as the gold standard in these cases, there are some advantages when dissection is performed close to the rectal wall. Some studies indicate that “near to TME ” dissection could be related to a lower pelvic complication rate as well as better functional outcome due to autonomic nerve preservation. Moreover, possible pitfalls and complications regarding anatomical issues and oncological outcome are also discussed.
In the 6th episode of the Ileal Pouch Series, Dr. Roel Hompes MD PhD explains the arguments in favor of close rectal dissection in cases of protectomy for benign disease.
Dr. Hompes highlights the benefits of this technique over TME dissection, mainly, less bleeding, nerve preservation, leak prevention and mitigation.In cases of FAP, close dissection is only beneficial if there is no suspicion of cancer, but more data is required.
In this lecture, Professor Antonino Spinelli talks about the use of fluorescence imaging to confirm vascularisation of the ileal pouch. Fluorescence imaging has been used widely in the recent years as a tool to evaluate perfusion in colorectal surgery. It appears to be of even more importance in pouch construction, but it needs refining and decisions must be guided by clinical experience.
