Within the last decade the customary trend of using non absorbable sutures has changed, with numerous studies and meta-analyses advocating the use of slowly absorbable sutures, claiming comparable wound strength with significantly lower incidence of wound complications. It was the objective of this randomized clinical trial to compare two universally accepted suture materials, the non-absorbable Nylon and the slowly absorbable Polydioxanone for midline abdominal closure in the Indian context.

Condition Intervention
Device: Suture for midline abdominal closure

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Single Blind (Subject)
Primary Purpose: Treatment
Official Title: Is Polydioxanone 'THE' Suture of Choice for Midline Abdominal Closure? Results of a Prospective Randomized Clinical Trial

Further study details as provided by Christian Medical College and Hospital, Ludhiana, India:

Primary Outcome Measures:
  • Wound Complications associated with suture material used for closure- Wound Dehiscence, Wound Infection, Incisional Hernia, Suture Sinus, Scar Pain [ Time Frame: 2 years ]

Secondary Outcome Measures:
  • Factors independent of suture materials responsible for wound complications such as age, gender, type of surgery, degree of contamination, surgeon, and presence of a stoma [ Time Frame: 2 years ]

Enrollment: 64

Surgical Patient undergoing midline laparotomy closure
Device: Suture for midline abdominal closure
closure with Polyamide or Polydioxanone
Other Name: Ethicon Inc., Loop no. 1, 150 cm suture length

Detailed Description:

64 patients undergoing midline laparotomy were allocated, using block randomization, to mass closure of the abdominal wall with continuous polyamide (34 patients) or continuous polydioxanone (30 patients).

There was an alarmingly higher incidence of wound dehiscence in the PDS group requiring secondary suturing (Nylon 0; PDS 5). Mid-way through the trial, an interim analysis was performed which revealed an unacceptably high incidence of wound dehiscence in the PDS group. This necessitated a premature curtailment of the study. There was, however, a statistically significantly higher incidence of scar pain in the Nylon group (Nylon 9; PDS 1).

There is a need for a study with larger series, and PDS as a choice of suture for midline wound closure cannot be recommended.
