Does the removal of retained staples really improve postoperative chronic sequelae after transanal stapled operations?

Partial Stapled Hemorrhoidopexy Versus Circumferential Stapled Hemorrhoidopexy for Grade III to IV Prolapsing Hemorrhoids: A Randomized, Noninferiority Trial

BACKGROUND

Long-term outcomes and efficacy of partial stapled hemorrhoidopexy are not known.

OBJECTIVE

The purpose of this study was to compare the long-term clinical efficacy and safety of partial stapled hemorrhoidopexy with circumferential stapled hemorrhoidopexy.

DESIGN

This was a parallel group, randomized, noninferiority clinical trial.

SETTINGS

The study was conducted at a single academic center.

PATIENTS

Patients with grade III/IV hemorrhoids between August 2011 and November 2013 were included.

INTERVENTIONS

Three hundred patients were randomly assigned to undergo either partial stapled hemorrhoidopexy (group 1, n = 150) or circumferential stapled hemorrhoidopexy (group 2, n = 150).

MAIN OUTCOME MEASURES

The primary outcome was the rate of recurrent prolapse at a median follow-up period of 5 years with a predefined noninferiority margin of 3.75%. Secondary outcomes included incidence and severity of postoperative pain, fecal urgency, anal continence, and the frequency of specific complications, including anorectal stenosis and rectovaginal fistula.

RESULTS

The visual analog scores in group 1 were less than those in group 2 (p < 0.001). Fewer patients in group 1 experienced postoperative urgency compared with those in group 2 (p = 0.001). Anal continence significantly worsened after both procedures, but the difference between preoperative and postoperative continence scores was higher for group 2 than for group 1. Postoperative rectal stenosis did not develop in patients in group 1, although it occurred in 8 patients (5%) in group 2 (p = 0.004). The 5-year cumulative recurrence rate between group 1 (9% (95% CI, 4%-13%)) and group 2 (12% (95% CI, 7%-17%)) did not differ significantly (p = 0.137), and the difference was within the noninferiority margin (absolute difference, -3.33% (95% CI, -10.00% to 3.55%)).

LIMITATIONS

The study was limited because it was a single-center trial.

CONCLUSIONS

Partial stapled hemorrhoidopexy is noninferior to circumferential stapled hemorrhoidopexy for patients with grade III to IV hemorrhoids at a median follow-up period of 5 years. However, partial stapled hemorrhoidopexy was associated with reduced postoperative pain and urgency, better postoperative anal continence, and minimal risk of rectal stenosis.

STARR with Contour Transtar for Obstructed Defecation Syndrome: Long-Term Results

INTRODUCTION

Obstructed defecation syndrome (ODS) is a widespread and disabling syndrome. With this study, we want to evaluate the long-term results of stapled transanal rectal resection (STARR) performed with Contour Transtar device in the treatment for ODS. A re-evaluation of 113 patients subjected to STARR from June 2007 to January 2010 was conducted.

METHODS

All the patients treated for symptomatic ODS with STARR with Contour Transtar were included in the study. We re-evaluate all patients treated in the study period with clinical examination and specific questionnaire to verify the stability of the functional results and the satisfaction at 5 years from surgery. Constipation was graded using the Agachan-Wexner constipation score; eventual use of aids to defecate and patient satisfaction were assessed preoperatively, 6 months and 5 years after surgery. Long-term complications were also investigated.

RESULTS

Constipation intensity decreased from the preoperative value of 15.8 (±4.9) to 5.2 (±3.9) (p < 0.0001) at 6 months and remained stable after 5 years (7.4 ± 4.1; p < 0.01). Patients who use laxatives and enema decrease from 74 (77%) and 27 (28%) to only 16 (17%; p < 0.001) and 5 (5%; p < 0.001), respectively, at 5-year follow-up. None continue to help themselves with digitations after surgery. Also the satisfaction rate remained stable (3.64 vs 3.81) during the 5 years of the study.

CONCLUSION

The long-term results have demonstrated the efficacy of the STARR with Contour Transtar in treating ODS and the stability over time of the defecatory improvements.
