Resected specimen evaluation, anorectal manometry, endoanal ultrasonography and clinical follow-up after STARR procedures

Table 1 Specimen and clinical data of the two groups under study

	STARR with double PPH-1 (15)	STARR with CCS 30 (15)
Specimen (mean)
Surface (cm2)	36.9	54.51
Volume (cc)	23.8	29.81
VAS postoperative score (mean)
1st day	2.55	1.3
2nd day	0.95	1.1
Post-operative morbidity	None	1 (3.3%)2
Hospital stay (mean)	3.4	3.1

¹Comparison is statistically significant (P < 0.05);

²One case of acute bleeding. Stapled transanal rectal resection (STARR) with PPH-1 vs STARR with CCS 30. VAS: Visual Analogical Scale.
