Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

EXPERIMENTAL: group A( TSTstarr+ group)
TSTstarr+ is a kind of modified STARR（stapled transanal rectal resection ） operation, compared to the traditional STARR operation, it does not need two staplers but with a larger diameter stapler, " +" means better . Patients in group A with severe prolapsed hemorrhoids will undergo TSTstarr+ operation .

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
the recurrence rate of the severe prolapsed Hemorrhoids after surgery
Time Frame: 2 years
780 patients will be enrolled in one year.All patients will be followed up for one year, and then calculate 1 year recurrence rate between TSTstarr+ group and PPH group
2 years

Secondary Outcome Measures

Secondary Outcome Measures

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (ANTICIPATED)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date.
