The value of honey dressings in pilonidal cyst healing: a prospective randomized single-center trial.

BACKGROUND: Honey is described as a wound healing agent. Many virtues have been attributed to it, in particular, antibacterial properties. The aim of our study was to evaluate its value in healing of wounds after wide excision on pilonidal cyst healing. METHODS: A prospective randomized trial was conducted from March 2016 to February 2022 which included patients with a persistent non healed wound which required packing 6 weeks after pilonidal cyst excision. Patients were randomly allocated to simple alginate wick dressings or the same design plus honey. RESULTS: Fifty patients were included in each arm. There were 57 men and 43 women. The median age was 22 years (range 19-28 years). The mean healing time was 61 (± 44) days in the wick + honey group compared to 78 (± 55) days in the simple alginate wick group (p = 0.094). There was no significant difference between the two groups in terms of time off work and time without physical activity The VQ-Dermato quality of life score was equivalent in both groups. CONCLUSIONS: Tolerability for honey dressings is good and is equivalent to that of alginate dressings in cavity wound care. This trial did not reach a significant difference in its primary endpoint but it shows the value of honey in this indication, although its use requires further study. TRIAL REGISTRATION NUMBER: CLINICAL TRIALS: NCT02485860 and EUDRACT: 2015-A00452-47 (10/03/2015).

Lack of benefit of routine abdominal CT-scan before bariatric surgery.

BACKGROUND: Scientific societies recommend to seek cancer prior to bariatric surgery. In our tertiary referral center, we aimed to study performance of abdominal CT-scan before bariatric surgery. PATIENTS AND METHODS: We retrospectively included all patients who underwent bariatric surgery and a pre-operative abdominal CT-scan in our academic center, between January 2015 and December 2018. RESULTS: We included 521 patients (417 women and 104 men) with a mean age of 48.0±11.5 years. Mean preoperative body mass index was 44.9±7.0kg/m2. Among the 392 patients with abnormal CT-scan, mean number of anomalies per patient was of 2.2±1.2. Vast majority of anomalies (91.8%) were non-significant. Only 5 (1%) patients needed treatment prior to bariatric surgery. No factor predictive of abnormal CT-scan was found. CONCLUSION: Only few patients had severe anomaly on CT-scan before bariatric surgery. Abdominal CT-scan could not be advocated to seek cancer before bariatric surgery.

Hypotonic Low Esophageal Sphincter Is Not Predictive of Gastroesophageal Reflux Disease After Sleeve Gastrectomy.

BACKGROUND: Sleeve gastrectomy is the most commonly performed bariatric surgery these days but is associated with de novo reflux. OBJECTIVE: We aimed to study the influence of hypotonic lower esophageal sphincter (LES) on postoperative gastroesophageal reflux disease (GERD). METHODS: Patients with pre- and postoperative esophageal high-resolution manometry (HRM) and 24-h pH monitoring (pHM) were included retrospectively in our study. Preoperative hypotonic LES was defined by a mean residual pressure of the lower esophageal sphincter < 4 mmHg. Postoperative GERD was defined by a DeMeester's score > 14.72. We also evaluated postoperative manometric changes at the esophageal-gastric junction. RESULTS: Sixty-nine patients (54 females and 15 males) had pre- and postoperative HRM and pHM. The mean age was 45.9 ± 9.8 years. The mean body mass index (BMI) was 47.5 ± 7.5 kg/m2. Hypotonic LES concerned 21 patients (30.4%) before sleeve gastrectomy. The mean time between the two esophageal monitorings was 32.1 ± 24.1 months. The sensitivity, specificity, positive predictive value, and negative predictive value of hypotonic LES to predict GERD were 31, 70, 52, and 48% respectively. The LES minimal residual pressure was not statistically decreased after sleeve gastrectomy (p = 0.24). Only the wave speed, esophageal length, and LES length were significantly reduced after SG (p = 0.029, 3.8 × 10-7 and 0.00032). CONCLUSION: Hypotonic LES has a poor predictive value on postoperative GERD. The LES's length is significantly reduced after SG and this could be a factor explaining de novo reflux.
