    Surgical site infection (SSI) remains a common postoperative morbidity, particularly in colorectal resections, and poses a significant financial burden to the healthcare system. The omission of mechanical bowel preparation, as is performed in enhanced recovery after surgery programmes, appears to further increase the incidence. Various wound protection methods have been devised to reduce the incidence of SSIs. However, there are few randomized controlled trials assessing their efficacy. The aim of this study is to investigate whether ALEXIS wound retractors with reinforced O-rings are superior to conventional wound protection methods in preventing SSIs in colorectal resections.

    AIM: The Sodergren score was developed to objectively measure the severity of haemorrhoidal symptoms. This study aimed to determine if there was a difference in the Sodergren score between patients who were offered surgery and patients who underwent successful rubber band ligation of internal haemorrhoidal disease and to assess its performance in guiding management.

    METHOD: This is a prospective, observational study. The preintervention Sodergren scores of subjects with internal haemorrhoidal disease were recorded and blinded to the surgeon in charge. Sodergren scores of subjects in the two arms were unblinded and compared at the end of the study.

    RESULTS: The results for 290 patients were available for final analysis. The median scores of those offered surgery and those who underwent successful rubber band ligation differed significantly [4 (interquartile range 3-10) vs 0 (interquartile range 0-4), P = 0.001]. In predicting treatment, the Sodergren score had an area under the receiver operating characteristic curve of 0.735 (95% CI 0.675-0.795).

    CONCLUSION: There is a significant difference in scores between patients who were offered surgery and patients with successful rubber band ligation. Our study suggests that the Sodergren score has an acceptable discrimination in predicting the need for surgery in internal haemorrhoidal disease. We propose that patients with a Sodergren score of 6 or more be considered for upfront surgery. This score could potentially be used to standardize outcomes of future haemorrhoid trials.

    AIM: Fistula-in-ano (FIA) is an anomalous passage between perianal skin and the anal canal or the rectum that presents many management difficulties. Ligation of intersphincteric fistula tract (LIFT) was introduced as a cost-effective sphincter-saving procedure with a reported success rate of 94.4%. Unfortunately, this procedure is technically challenging, and recently submucosal ligation of fistula tract (SLOFT), a simplification of LIFT, was proposed. Our aim was to assess the SLOFT technique over a longer follow-up period to determine its effectiveness.

    METHOD: A prospective observational study was performed in 47 patients with FIA treated by SLOFT from September 2017 to February 2019.

    RESULTS: There were 47 patients, of whom 33(70.2%) were men. The median age was 39 years (range 30-50 years). All the patients had primary FIA of cryptoglandular origin. The patients were followed up for 1 year and were postoperatively assessed at 2, 4, 12 and 24 weeks and 1 year. The median body mass index was 27.3 kg/m2 (range 24.3-29.4 kg/m2 ) and the median duration of surgery was 15 min (range 13-20 min). Most (83.0%) of the fistulas were trans-sphincteric. The success rates at the end of 24 weeks and 1 year were 87.2% and 80.9%, respectively. No postoperative incontinence was recorded.

    CONCLUSION: In our series the success rate of SLOFT was 80.9%. There were no sphincter-related complications. Repeat SLOFT was feasible for cases of recurrence. Therefore, SLOFT should be considered an alternative sphincter-saving procedure to LIFT for the management of FIA.
