Laser hair removal after surgery vs. surgery alone for the treatment of pilonidal cysts: a retrospective case-control study

BACKGROUND

Based on the presumed role of hair in pilonidal cyst (PNC) pathogenesis, laser epilation has been used to decrease recurrences. However, most of the data rely on case reports and uncontrolled series, and the rare controlled studies reported conflicting results. The objective of this study was to investigate the efficacy of laser hair removal (LHR) to decrease the recurrence rate after surgery of PNC vs. surgery alone.

METHODS

We conducted a retrospective monocentric case-control study in the departments of Pediatric Surgery and Laser Center of Dermatology of the University Hospital of Nice in France from January 2010 to June 2017. We included all patients with PNC who had surgery during the period, and we compared patients who had LHR after surgery to those having surgery alone. The main outcome was the prevalence and number of recurrences of PNC in each group.

RESULTS

Twelve patients - eight treated with alexandrite laser and four patients with Nd : YAG - were included in the cases group; 29 patients treated with surgery alone were included in the control group. The mean and the median number of laser sessions were 4.2 and 5, respectively (extremes 1-10). The postsurgical recurrence rate without LHR was 51.7%, and their number varied from 1 to 3. A significant decrease in the recurrence rate was observed after LHR (8.3%) compared to control group (P < 0.001). The median duration before recurrence was 14 months for surgery alone. The median follow-up was 18 months (1-30 months) for LHR group and 30 months (6-72 months) for surgery alone group. Two patients had abnormal healing or persistent sinus after surgery alone compared to none in the group who undergone laser procedure after surgery.

CONCLUSIONS

Laser hair removal decreases the risk of delayed healing and of recurrences of PNL after surgical procedure.

Evaluation of single incision laparoscopic surgery "low-fidelity" simulation training

GOAL

Evaluate the learning curve of SILS (Single Incision Laparoscopic Surgery) on a simulator, based on two tests of the Fundamentals of Laparoscopic Surgery certification program (FLS(®)), in a population of novice medical students, and compare their performance to those of senior surgeons practicing both "conventional" laparoscopic surgery and SILS.

MATERIALS AND METHODS

Monocentric prospective study with four groups: two groups of novice medical students, and two groups of senior surgeons. The two FLS(®) tests used for evaluation were the peg transfer and the precision cutting tasks.

RESULTS

No statistically significant differences were found between the novice groups, whether they started their first session directly, or immediately after watching a video presentation of the exercises. For the novice medical students, the average completion time of both tests improved significantly between the first and the sixth sessions with a short learning curve. The group of experienced seniors performed fastest in both tests. For the peg transfer task, the skills of the novice medical students were comparable to those of non-experienced seniors after the 4th session and improved after 6 sessions (P=0.017). For the precision cutting task, the average timing of the novice group became better than that of the non-experienced seniors, starting from the third session.

CONCLUSIONS

FLS(®) "low fidelity" simulator training is effective for the training of novice medical students. To minimize the risk of technical errors, novice medical students should practice a minimum of six simulator-training sessions before starting their practical learning of SILS in the operating room.

[Who limit vaginal birth for breech presentation: medical practice or Law? Discussion between a medical doctor, a lawyer and the head chief of an university hospital]

The mode of delivery of breech presentation still remains a debate in France. Despite the medical arguments, themselves in debate, exists a legal pressure felt by medical practitioners. Our study highlights the different opinions of medical practitioners, lawyers and medical teachers faced with breech presentation.

[A role of robotic-assisted surgery to preserve female fertility? Comments about the first paratubal cystectomy performed with the "Da Vinci S" robotic system in a young girl]

In the field of adnexal surgeries in children, robotic surgery seems to make easier the realization of minimal invasive surgery. It could lead to a decrease of post-surgical adherences and therefore preserve the fertility of young patients. We report the first paratubal cystectomy performed using robotic assistance on a child in order to preserve her future fertility and discuss advantages and disadvantages of this technology.

Transumbilical approach for shunt insertion in the pediatric population: an improvement in cosmetic results

OBJECTIVE

In spite of the recent interest in endoscopic third ventriculostomy, ventriculoperitoneal (VP) shunt is still the gold standard in treating non-obstructive hydrocephalus in children. The peritoneal cavity remains the optimal site for cerebrospinal fluid (CSF) diversion. Shunt insertion and re-interventions carry a high risk of inaesthetic abdominal scars and long-term morbidity. We report a technique of transumbilical shunt insertion, which provides better cosmetic results and without many more complications. This approach has been performed for a long period in a wide variety of intra-abdominal conditions by pediatric surgeons.

METHODS

Between March and October 2003, we inserted 12 VP shunts in children. For eight consecutively treated children the follow-up is more than 3 months. All the shunts were inserted through the umbilicus. These eight children are the subjects of this study. Indications for shunting were: communicating hydrocephalus (6 cases), subdural hematoma (1 case), and hygroma associated with an arachnoid cyst (1 case). The population consisted of 7 boys and 1 girl, ranging in age between 6 weeks and 47 months (mean age: 15 months), and their body weights varied between 2,110 g and 18,000 g (mean weight: 8,470 g). All children were examined twice a day for 3 days, and wounds were examined daily to check for the absence of sepsis or dehiscence. Clinical controls were performed 1 month after discharge. The operating surgeon was invited to comment on any difficulties encountered in making or closing this incision afterwards.

RESULTS

The average length of clinical follow-up was 6 months (range 4-7 months). One infection of the VP shunt occurred. It was treated with external drainage and antibiotics. After 1 week, a second VP shunt was inserted using the same technique without particular difficulty and with a nice cosmetic result. Concerning the seven other children, the cosmetic results were optimal, with no puckered abdominal scars or wound dehiscence, and with no perioperative or long-term complications related to the umbilical approach.

CONCLUSION

At this early follow-up, umbilical incision for shunt insertion is a safe and easy technique. It provides an optimal cosmetic result, even in cases of re-intervention. This minimally invasive surgery does not require long specialized training. We have not shown an increase in complications associated with a "learning curve." Longer follow-up is needed to evaluate the risk of infection.

Sacral neuromodulation for neurogenic bladder dysfunction in children

PURPOSE

We report a prospective randomized controlled study to evaluate the possible benefits of sacral neuromodulation (SNM) for the management of neurogenic bladder dysfunction in children.

MATERIALS AND METHODS

We included in the study subjects between the ages of 5 and 21 years presenting with urinary incontinence due to neurogenic bladder. Before study inclusion all previous treatment was discontinued. Patients were randomly divided into the control group treated conventionally and the implant group treated with SNM. Treatment outcome was compared every 3 months for a minimum of 12 months based on clinical examination, voiding diary and urodynamic evaluation.

RESULTS

A total of 26 boys and 16 girls with a mean age of 11.9 years were enrolled in this study. There were 21 patients in each group. The main underlying etiology was spina bifida. The 2 groups were comparable with regard to sex, age and urodynamic variables. Total disappearance of urinary leakage was observed in 1 patient who underwent implantation but he still required intermittent catheterization. Comparison of urodynamic variables disclosed no significant statistical difference except with regard to functional bladder capacity which was better in the control group and the leak point pressure which was better in the implant group (p <0.05). Evaluation of interindividual variations in the implant group revealed significant improvement in compliance and functional bladder capacity at 6 and 9 months but not at 12 months. Nine patients in the implant group reported improvement in intestinal transit, 5 total disappearance of urinary infection and 6 persistent sensation of a full bladder. No patient in the control group reported any improvement. Revision surgery was required in 3 cases due to lead migration, faulty connection and wound infection.

CONCLUSIONS

SNM is a promising new therapeutic modality. Implant placement is minimally invasive, nondestructive and reversible. Use in children with neurogenic bladder has not been previously reported. Although some improvement was noted in patients treated with SNM, the difference with the control group was not significant. A larger multicenter study is warranted to evaluate SNM.

Umbilical one-puncture laparoscopic-assisted appendectomy in children

To perform a laparoscopic appendectomy, three trocars are usually needed. In order to reduce abdominal wall trauma, we have adopted an umbilical one-puncture laparoscopic-assisted appendectomy (UOPLAA). We did a retrospective study of UOPLAA performed during last 2 years on 200 children aged from 5 to 18 years (median, 9 years). The patients were selected after clinical examination. No child with advanced generalized peritonitis or an abscess with a palpable mass was a candidate for this technique. UOPLAA was successful in 184 patients (92%). In 16 cases (8%), an additional trocar was required to manage perforated or retrocecal appendicitis. The mean operative time was 15 min, and the mean hospital stay was 2 days. There were no intraoperative complications. There were 10 (5%) postoperative complications (three parietal and seven intraabdominal). Four patients (2%) needed reoperation under general anesthesia. The UOPLAA is our preference in cases of acute nonperforated appendicitis because it is simple and fast, with good cosmetic results; but in 8% of our cases, an intraoperative difficulty (retrocecal location, abnormal adhesive band, peritonitis, etc.) arose that required the introduction of additional devices to ensure the safety of the laparoscopic procedure.
