Brief Summary

Perianal abscess is a purulent infection of the tissues surrounding the anal canal and rectum. The postoperative wound is prone to infection, and the literature indicates that hip bathing is helpful to prevent infection, reduce edema, and promote healing. Therefore, patients need to use a bidet for medical sitz bath to avoid infection and contamination. The bidet on the market is divided into ordinary type and rinse type (manual or electric). There are no high-quality studies comparing the effects of these sitz baths. A prospective randomized controlled trial was designed to investigate the effects of regular sitz bath, manual irrigation, and electric irrigation. A total of 102 patients with perianal abscess in the Affiliated Hospital of Putian University were included in the study. The patients were 18-75 years old and underwent surgical treatment. Patients with recurrent abscess, anal fistula, mental disease, pregnant or lactating women, and diabetes were excluded. The patients were divided into general group, manual group and electric group by random number table method, with 34 cases in each group. All patients received hip bathing with 0.02% potassium permanganate solution at 41-43 ° C three times a day for 10-15 minutes each time after surgery.

Outcome Measures

Primary Outcomes (1)

• Wound healing time

  The effectiveness of different sitbath methods in promoting recovery after perianal abscess was demonstrated by the healing time of the patient's surgical wound.

  Daily from Day 1 until complete epithelialization (max 60 days post-op)

Secondary Outcomes (2)

• Complication incidence

  Time Frame: Within 30 days postoperatively

• pain and swelling

  Day 1, 3, 5, 7, and Day 14±2

Study Arms (3)

conventional group

NO INTERVENTION

Patients in the conventional group were advised to use a regular bidet without a flusher after surgery. The patient was treated with potassium permanganate sitz bath from the first postoperative day. The concentration of potassium permanganate solution used in the sitz bath was 0.02%. The patient had a sitz bath three times a day (9:00, 13:00, and 17:00) and the perianal area was scrubbed through a cotton cloth. Each sitz bath lasts 10-15 minutes and the water temperature is 41-43 ° C.

Manual group

EXPERIMENTAL

Patients in the manual group were advised to use a manual flushing bidet with an irrigator after surgery. The patient was treated with potassium permanganate sitz bath from the first postoperative day. The concentration of potassium permanganate solution used in the sitz bath was 0.02%. The patients were advised to have a sitz bath three times a day (9:00, 13:00, 17:00). By manually pressing the airbag, the potassium permanganate solution in the bidet was sprayed with the rinsing device to achieve the purpose of cleaning the perianal area. The duration of each sitz bath was 10-15 minutes, and the water temperature was 41-43 ° C.

Behavioral: Ordinary sitz bath, manual flushing sitz bath, electric flushing sitz bath

electric group

EXPERIMENTAL

Patients in the electric group were advised to use an electric flushing bidet with an irrigator after surgery. The patient was treated with potassium permanganate sitz bath from the first postoperative day. The concentration of potassium permanganate solution used in the sitz bath was 0.02%. The patients were advised to take a sitz bath three times a day (9:00, 13:00, 17:00), and spray potassium permanganate solution in the bidet through an electric douche to achieve the purpose of cleaning the perianal area. The duration of each sitz bath was 10-15 minutes, and the water temperature was 41-43 ° C.

Behavioral: Ordinary sitz bath, manual flushing sitz bath, electric flushing sitz bath
