Perineal stapled rectal resection with Contour Transtar

Perineal stapled prolapse resection for full-thickness external rectal prolapse: a multicentre prospective study

AIM

Many different surgical techniques have been reported for the surgical treatment of full-thickness external rectal prolapse. Perianal stapled prolapse resection (PSP) is a relatively newly reported technique for full thickness external rectal prolapse. The aim of this prospective multicentre study was to evaluate the results of this procedure.

METHOD

Consecutive patients who underwent a PSP resection for full-thickness external rectal prolapse at five centres were recruited to the study. Median operating time, hospital stay, complications, recurrence and functional results according to the Wexner Incontinence Scale and obstructive defaecation syndrome score were recorded.

RESULTS

There were 27 patients treated by PSP. The median Wexner incontinence score improved from 10 presurgery to 5 after surgery (P < 0.001); the median obstructed defaecation syndrome score improved from 12 presurgery to 5 (range 4-10) after surgery (P < 0.001). A laparoscopically assisted procedure was performed in three patients (11.1%). The median number of cartridges used was six (range four to nine). The median operating time was 48 min. Early complications occurred in six patients (22.2%) and late complications in two (7.4%). The median length of hospital stay was 5 days. The recurrence rate at a median follow-up of 30.3 months was 14.8%.

CONCLUSION

PSP appears to be an easy, fast and safe procedure. Early functional results are good. The recurrence rate compares favourably with other perineal procedures like the Delorme or the Altemeier operations. Long-term functional results need to be investigated further.

[Operative therapy of external rectal prolapse with a stapler]

External rectal prolapse is a rare condition, which is more common in old and multimorbid women. In recent years five surgical methods have become established from among the multitude of operative procedures which have been described. One of the most recent techniques is perineal stapled prolapse resection (PSP) which is described in this article. After complete eversion of the rectal prolapse it is resected into 2 halves using a linear cutter by incisions at 3 o'clock and 9 o'clock lithotomy positions, followed by stepwise resection with a curved cutter along the ventral and dorsal circumference. There is low evidence for the treatment of external rectal prolapse. For PSP only case series exist with results that are similar to those from other techniques; however, comparative studies are nearly completely lacking. The PSP is a relatively new surgical technique for the treatment of external rectal prolapse. It is a safe surgical procedure. Due to the lack of evidence it should remain reserved for old and/or multimorbid patients.

Impact of prolapse mass on Contour Transtar technique for third-degree rectal prolapse

PURPOSE

Contour Transtar procedure for rectal prolapse is a promising technique according to safety and efficacy. One potential surgical problem is failure of the stapler due to the thick rectal wall. In order to evaluate the practicability and the impending limitations of the Contour Transtar technique, we reviewed our data with special respect to the necessity of additional anastomosis suturing.

METHODS

A prospective analysis of 25 consecutive patients, which underwent Contour Transtar procedure from January 2009 to July 2012, was performed. For statistic analysis, the groups with and without additional suturing of the anastomosis were evaluated according to patient characteristics and surgical outcome.

RESULTS

Twenty-five patients, three men and 22 women, underwent transanal Contour Transtar stapling procedure for rectal prolapse. Due to stapling failure, additional suturing of the anastomosis was necessary in 4 of 25 procedures (16%). Age (74.1 vs. 83.1 years) and body mass index (30.8 vs. 22.7 kg/m(2)) were significantly different with and without additional suturing. Operative time was longer (62 vs. 31 min), more cartridges were used (12 vs. 6), and the specimen weight was higher (220 vs. 107 g) in patients with additional suturing. Early postoperative complications were observed in two patients without anastomosis suturing including one patient with bleeding and systemic inflammatory reaction in one case. Postoperative stay did not differ between both groups.

CONCLUSION

Patients with extensive obesity, which present with a substantial rectal prolapse, may need additional suturing of the rectal anastomosis after Contour Transtar stapling. This causes prolonged operative time. However, this does not correlate with complications and it is not related to significant longer hospital stay.
