A transanal procedure using TST STARR Plus for the treatment of Obstructed Defecation Syndrome: 'A mid-term study'.

PURPOSE

The aim of this study was to assess the safety, efficacy and outcomes of TST STARR (Stapled Transanal Rectal Resection) plus to treat Obstructed Defecation Syndrome (ODS) at mid-term follow-up.

METHODS

From April 2013 to September 2014, 50 cases (7 male patients) with ODS caused by rectocele and/or internal rectal prolapse were treated with the new TST STARR Plus. Clinical data from the 18 month mid-term follow up, including efficacy and constipations were recorded.

RESULTS

The average duration of surgery was 21 ± 4 min (range 12-35 min). The average postoperative hospital stay was 5 days (range 4-8 days). The pathological findings showed that the specimens contained full-thickness rectal tissue in all patients. The mean volume of resected specimen was 12.3 cm(3). Postoperative complications included five cases with transient faecal urgency that dissipated after 3 months; one patient suffered anastomotic bleeding on the sixth day after surgery, with successful haemostasis achieved through conservative therapy. The Wexner constipation score improved in patients affected by ODS from 13.96 ± 2.37 preoperatively to 7.00 ± 3.90, 7.28 ± 3.91, 8.10 ± 4.05 and 8.44 ± 4.08 at 3,6,12 and 18 months postoperatively, respectively, with all p < 0.05. Overall outcome was reported as ''excellent'' in 42% of patients, ''good'' in 36% of patients, ''adequate'' in 12% of patients, and ''poor'' in 10% of patients after 18 months of follow-up.

CONCLUSIONS

The TST STARR Plus is a simple, safe, and effective option for selected patients with ODS. Long-term prospective clinical studies are needed to validate the advantages of this emerging, novel procedure.
