Continuous versus interrupted sutures for repair of episiotomy or second-degree perineal tears: a randomised controlled trial.

OBJECTIVE: To evaluate the repair techniques of continuous and interrupted methods for episiotomy or perineal tears. DESIGN: A randomised controlled trial. SETTING: The Hospital Universitario Principe de Asturias, a state hospital belonging to the community of Madrid. SAMPLE: Four hundred forty-five women who had undergone vaginal deliveries with episiotomies or second-grade tearing of the perineum between September 2005 and July 2007. METHODS: One group was repaired with continuous, nonlocking sutures involving the vagina, perineum, and subcutaneous tissues. The other group had continuous, locking sutures of the vagina, interrupted sutures in the perineal muscles, and interrupted transcutaneous sutures. The threads used for stitching were identical in both groups. MAIN OUTCOME MEASURES: The participants were questioned regarding the sensation of pain and the use of painkillers on the second and the tenth days, and 3 months postpartum. RESULTS: When comparing the group with continuous suture to the group with interrupted sutures, the differences included less repair time (1 minute; P= 0.017) and less suture material used (relative risk [RR], 3.2, 95% CI: 2.6-4.0). The comparison of pain on the second and tenth days, and 3 months postpartum were not statistically different between the two techniques (RR, 1.08, 95% CI: 0.74-1.57; RR, 0.96, 95% CI: 0.59-1.55; and RR, 0.68, 95% CI: 0.19-2.46, respectively). CONCLUSIONS: Although we did not demonstrate that one technique was better than the other in the incidence of pain in the short or long term, we showed that episiotomy and perineal tear repairs with continuous suturing were quicker and used less suture material without an increase in complication than interrupted suturing.

[Botulinum toxin is effective in the short-term treatment of esophageal achalasia. Preliminary results of a randomized trial]. / La toxina botulínica es efectiva en el tratamiento a corto plazo de acalasia esofágica. Resultados preliminares de un estudio randomizado.

UNLABELLED: Botulinum toxin (BoTox) is a potent inhibitor of the release of acetylcholine from terminal nerves and has been used successfully in spastic disorders of skeletal muscle. Its used for the treatment of disorders of gastrointestinal smooth muscle has recently been explored. In this study we evaluated the efficacy of transendoscopic injection of BoTox in 13 symptomatic patients with achalasia G II (Siewert classification) without previous treatment of an ongoing randomized-controlled trial. Patients were blindly randomized to administrate: a) 8OU of BoTox were injected in four quadrants (1 ml in each quadrant-20 U/ml) (n = 8), b) normal saline solution as placebo injected in the same way (n = 5). Patients who did not respond were retreated in an open design with the same schedule of BoTox. BoTox or placebo were injected directly into the lower esophageal sphincter (LES), located by manometric and endoscopic procedures, via sclerotherapy injector. Response to treatment was assessed by changes in symptoms score, weight, LES pressure, barium esophagograms and endoscopy. All determinations were repeated at basal and after 7-30-60 and 90 days of treatment. Post treatment response was considered positive if at one month, 3 of 4 parameters were improved. No evidence of response to BoTox were assessed in 3 patients. At 90 days, 10 patients remain well and data are as follows: (mean +/- SD) symptoms score: (Pre: 3.23 +/- 0.44) (Post: 1.31 +/- 0.95); LES pressure (mmHg) (Pre: 53, 15 +/- 66.31 +/- 7.49); % reduction of esophageal diameter 55% (p < 0.0001) (pair T-test). Relaxation of LES did not change after treatment. There were no side effects related to BoTox injection. CONCLUSIONS: Endoscopic intrasphincteric BoTox injection is safe, simple and effective in the short term treatment for achalasia. Further studies are necessary for evaluation of long term effects.

Botulinum toxin (BoTox) is a potent inhibitor of the release of acetylcholine from terminal nerves and has been used succesfully in spastic disorders of skeletal muscle. Its used for the treatment of disorders of gastrointestinal smooth muscle has recently been explored. In this study we evaluated the efficacy of transendoscopic injection of BoTox in 13 symptomatic patients with achalasia G II (Siewert classification) without previous treatment of an angoing randomized-controlled trial. Patients were blindy randomized to administrate: a) 8OU of BoTox were injected in four quadrants (1 ml in each quadrant-20 U/ml) (n=8) normal saline solution as placebo injected in the same way (n=5). Patientes who did not respond were retreated in an open design with the same schedule of BoTox. BoTox or placebe were injected directly into the lower esophageal sphincter (LES), located by manometric and endoscopic procedures, via sclerotherapy injector. Response to treatment was assessed by changes in symptoms score, weight, LES pressure, barium esophagograms and endoscopy. All determinations were repeated at basal and after 7-30-60 and 90 days of treatment. Post treatment response was considered positive if at one month, 3 of 4 parameters were improved. No evidence of response to BoTox were assessed in 3 patients. At 90 days, 10 patients remain well and data are as follows: (X + SD) symptoms score: (Pre: 3.23 + 0.44) (Post: 1.31 + 0.95); LES pressure (mmHg) (Pre: 53,15 + 66.31 + 7.49); per cent reduction of esophageal diameter 55 per cent (p< 0.0001) (pair T-test). Relaxation of LES did not change after treatment. There were no side effects related to BoTox injection. Conclusions: Endoscopic intrasphincteric BoTox injection is safe, simple and effective in the short term treatment for achalasia. Further studies are necessary for evaluation of long term effects.
