Jump Technique versus Seton Method for Anal Fistula Repair: A Randomized Controlled Trial

Flowchart in Post-Bariatric Surgery: A Research for the Appropriate Type and Timing of Plasties Reshaping the Body

INTRODUCTION

Obesity is a chronic disease with significant health implications. Bariatric surgery is an effective treatment for obesity-related conditions. However, the timing of post-bariatric body contouring surgery remains uncertain.

MATERIALS AND METHODS

We conducted a retrospective study of 1336 patients who underwent bariatric surgery. We analyzed weight trends and variations after different types of bariatric procedures. The Pittsburgh Index was used to evaluate body contouring outcomes.

RESULTS

The majority of patients were women, and sleeve gastrectomy was the most common procedure. Weight loss varied depending on the surgery type, with different outcomes for male and female patients. The Pittsburgh Index remained stable in most cases.

CONCLUSION

Our findings suggest that the timing of body contouring surgery should be tailored to the type of bariatric procedure performed. Abdominoplasty is recommended as a last procedure for sleeve gastrectomy patients, while gastric bypass patients are suitable candidates for early abdominoplasty. Biliopancreatic diversion patients should stabilize their weight before abdominoplasty. The Pittsburgh Index is a valuable tool for assessing the timing of post-bariatric plastic surgery. Further research is needed to optimize surgical planning and outcomes.

Cutting seton for the treatment of cryptoglandular fistula-in-ano: a systematic review and meta-analysis

BACKGROUND

The use of cutting seton (CS) for the management of cryptoglandular fistula-in-ano has remained controversial because of reports of fecal incontinence, postoperative pain, and extended healing time. The aim of this review was to provide the first synthesis of studies investigating the use of CS for the treatment of cryptoglandular fistula-in-ano.

METHODS

MEDLINE, Embase, and CENTRAL were searched up to October 2022. Randomized controlled trials and observational studies comparing CS with alternative interventions were included, along with single-arm studies evaluating CS alone. The primary outcome was fistula-in-ano recurrence, and secondary outcomes included incontinence, healing time, proportion with complete healing, and postoperative pain. Inverse variance random-effects meta-analyses were used to pool effect estimates.

RESULTS

After screening 661 citations, 29 studies were included. Overall, 1513 patients undergoing CS (18.8% female, mean age: 43.1 years) were included. Patients with CS had a 6% (95% CI: 3-12%) risk of recurrence and a 16% (95% CI: 5-38%) risk of incontinence at 6 months. CS patients had an average healing time of 14.6 weeks (95% CI: 10-19 weeks) with 73% (95% CI: 48-89%) of patients achieving complete healing at 6 months postoperatively. There was no difference in recurrence between CS and fistulotomy, advancement flap, two-stage seton fistulotomy, or draining seton.

CONCLUSIONS

Overall, this analysis shows that CS has comparable recurrence and incontinence rates to other modalities. However, this may be at the expense of more postoperative pain and extended healing time. Further comparative studies between CS and other modalities are warranted.

Efficacy of different surgical treatments for management of anal fistula: a network meta-analysis

PURPOSE

Currently, the anal fistula treatment which optimises healing and preserves bowel continence remains unclear. The aim of our study was to compare the relative efficacy of different surgical treatments for AF through a network meta-analysis.

METHODS

Systematic searches of MEDLINE, EMBASE and CENTRAL databases up to October 2022 identified randomised controlled trials (RCTs) comparing surgical treatments for anal fistulae. Fistulae were classified as simple (inter-sphincteric or low trans-sphincteric fistulae crossing less than 30% of the external anal sphincter (EAS)) and complex (high trans-sphincteric fistulae involving more than 30% of the EAS). Treatments evaluated in only one trial were excluded from the primary analyses to minimise bias. The primary outcomes were rates of success in achieving AF healing and bowel incontinence.

RESULTS

Fifty-two RCTs were included. Of the 14 treatments considered, there were no significant differences regarding short-term (6 months or less postoperatively) and long-term (more than 6 months postoperatively) success rates between any of the treatments in patients with both simple and complex anal fistula. Ligation of the inter-sphincteric fistula tract (LIFT) ranked best for minimising bowel incontinence in simple (99.1% of comparisons; 3 trials, n = 70 patients) and complex anal fistula (86.2% of comparisons; 3 trials, n = 102 patients).

CONCLUSIONS

There is insufficient evidence in existing RCTs to recommend one treatment over another regarding their short and long-term efficacy in successfully facilitating healing of both simple and complex anal fistulae. However, LIFT appears to be associated with the least impairment of bowel continence, irrespective of AF classification.
