Appraisal of the LIFT and BIOLIFT procedure: initial experience and short-term outcomes of 33 consecutive patients.

PURPOSE

A new sphincter-saving technique known as the LIFT (ligation of intersphincteric tract) procedure has gained growing interest. Use of a bioprosthetic device has also been suggested to augment the LIFT procedure (BIOLIFT). This study evaluates outcomes of patients undergoing LIFT and BIOLIFT for repair of complex anal fistulae.

METHODS

This study is a single-surgeon, single-centre retrospective review of a prospectively collected database. Study was conducted at Royal Prince Alfred Hospital Department of Colorectal Surgery, Sydney, Australia, from May 2009 to April 2012. Thirty-three patients were evaluated. Twenty-nine LIFTs and five BIOLIFT procedures were evaluated. Primary success is defined as successful healing from initial procedure while secondary success is successful healing after management of failure or recurrence.

RESULTS

In a cohort of predominantly female (67 %) and 94 % transsphincteric fistulae, primary success was 63 %. At a median follow-up of 20 weeks (6-81 weeks), there were 11 failures and one recurrence. The median time to failure/recurrence was 3 weeks (1-25 weeks). Six patients had a subsequent fistulotomy and three patients had a BIOLIFT for non-successful outcomes. The median follow-up for those with failures/recurrences is 60 weeks (range 20-76 weeks) and secondary success was 88 %. Post-operative anal manometry studies showed a 9 % reduction of resting and 11 % reduction of squeeze pressures but this was not statistically significant. There was also no post-operative incontinence. Anterior fistulas were noted do significantly worse (47%) compared with non-anteriorly located fistulas (84 %; p = 0.03).

CONCLUSIONS

LIFT and BIOLIFT procedures can be performed safely and effectively in a technically demanding study cohort of predominantly females with complex fistulas. Anterior fistulas have a higher risk of failure but present early and are amendable to repeat procedures. In particular, fistulotomies are useful in downstaged tracts and performing BIOLIFTs is an alternative in the management of LIFT failures and recurrences.
