gastropexy suture type and method of placement among the 18 IRs in the group.


My post was meant to garner information from other groups regarding their practices and to assess what evidence they have used to guide their practice.


What post or posts were most valuable to you and why? Peter Bream, MD, FSIR, shared his personal experiences, which, like mine, spanned a relatively long timeframe and multiple practice settings and, in addition, provided peer-reviewed literature and unpublished internal data as a basis for his comments and decision-making.


Will you, or have you, changed your practice patterns based on responses from SIR Connect? Based on some of the feedback and literature we received from the SIR Connect forum, and discussion within our IR section, we are creating a standardized management approach to enteral access patients.

correct use of gastrostomy tube and the presence of buttons on the skin.7,8,10 A recent retrospective study reported that immediate removal of T-fasteners demonstrated no statistically significant difference in major or minor complication rates when compared with delayed 2-week removal (major, 2% vs. 1.4%; minor, 7.9% vs 6.8%).11


Similarly, Foster


et al. (2009) reported that T-fastener removal at 2 days resulted in no major and only 14% minor complications which resolved with removal.10


A prospective study on absorbable gastropexy anchors mentions that the manufacturer manual outlines a suture absorption timeframe well before 90–110 days.7,12


Absorbable gastropexy anchors


Gastropexy fixation has been to


prevent stomach movement during tube insertion, promote tract maturation and mitigate the risk of complications such as peritoneal leaks and disolodgement.6–9 The aftercare of patients who have received PRG placement with absorbable gastropexy sutures poses questions regarding suture lifespan. The original post described follow-up protocol for gastropexy suture removal in primary PRG patients.


A randomized comparison study of PRG with and without T-fastener gastropexy demonstrated 10% incidence of serious complications without gastropexy.9


have been shown to remain in place for at least three weeks after insertion and may not fully absorb, leading to complications such as site pain, infection or T-fastener migration.7,11,13


Given the variable


behavior of absorbable gastropexy sutures to retain themselves or slough off on their own in the gastrointestinal tract, time to tract maturation, and potential for local complications, many IRs recommend follow-up within 2–3 weeks post-procedure to ensure


As pointed out by the original poster and members of SIR Connect, there are often logistical difficulties with respect to ease of access to health care and social determinants that inhibit the ability of many patients to follow up at a later time period (within 2–4 weeks). PRG placement technique, gastropexy suture type and follow-up protocol (respondents on SIR Connect generally follow up before 6 weeks) also differ by physician and institution. Many respondents on SIR Connect have observed the fact that T-fasteners do not necessarily fall off on their own in a timely fashion. This may highlight a potential role for early T-fastener removal in these patient populations, especially with the variable data we currently have on absorbable gastropexy suture self-release.
