None of the techniques that were compared significantly reduced the incidence of adhesive small bowel obstruction .
None of the specific techniques that were compared reduced the two main adhesion-related clinical outcomes , small bowel obstruction and infertility .
The meta- analysis provides little evidence for the surgical principle that using less invasive techniques , introducing less foreign bodies or causing less ischaemia reduces the extent and severity of adhesions
INTRODUCTION Adhesion formation is the most common complication following  peritoneal surgery  and the leading cause of small bowel obstruction , acquired infertility and inadvertent organ injury at reoperation .
Using a ' good surgical technique ' is advocated as a first step in preventing adhesions .
However , the evidence for different surgical techniques to reduce adhesion formation needs confirmation .
Evaluation of unilateral versus bilateral ovarian drilling in clomiphene citrate resistant cases of polycystic ovarian syndrome
Objectives Laparoscopic ovarian drilling ( LOD ) has been put forward as the treatment of choice in women with clomiphene citrate (CC)-resistant polycystic ovary syndrome ( PCOS ) , with tubo-ovarian adhesion formation as the major disadvantage . Our study proposed to compare the efficacy of laparoscopic unilateral ovarian drilling with bilateral ovarian drilling in terms of ovulation and pregnancy rate with the expected advantage of decreasing postoperative adhesion rate and change in fimbiro ovarian relationship with unilateral drilling . Methods This prospect i ve r and omized study included 44 patients with anovulatory infertility due to PCOS . Twenty-two patients underwent unilateral ovarian drilling  in group-I and 22 patients underwent bilateral ovarian drilling in group-II between June 2005 and June 2007 . The number of drilling site in each ovary was limited to five . The clinical and biochemical response , ovulation and pregnancy rates over a follow-up period of 1 year were compared . Tubo-ovarian adhesion rate was compared during cesarean section or during repeat laparoscopy . Results There was no statistical difference between the two groups in terms of clinical and biochemical response , ovulation rate and pregnancy rate . Postoperatively , tubo-ovarian adhesions could be assessed in 36.3 % of the patients and no adhesions were found in a single case in either group . Conclusion Unilateral drilling cauterization of ovary is equally efficacious as bilateral drilling in inducing ovulation and achieving pregnancy .  Unilateral ovarian drilling may be a suitable option in clomiphene citrate resistant infertility patient of PCOS which can replace bilateral ovarian drilling with the potential advantage of decreasing the chances of adhesion formation
