Single port surgery in pediatric age: report of first 300 cases.

BACKGROUND: In recent years, evolution of surgery has led to laparoscopy and then to single port surgery. In pediatric age, few papers have been published about single port procedures; in particular, no one has described the use of the Octoport device (Frankenman International Ltd., Suzhou, China). We present our experience using a new device. METHODS: A retrospective analysis of first 300 cases was performed collecting the data of all patients treated with Octoport device from October 2017 to September 2021. Epidemiological data, diagnosis, operative times, and complications were analyzed. Postoperative pain was compared with standard laparoscopy. RESULTS: A total of 300 procedures were performed during the study period. The age range was 1-17 years. The conversion rate was 3.6% (11 patients) including both conversion to traditional laparoscopy and to laparotomy. Pain management was comparable to traditional laparoscopy. The complication rate was 3.6%, in one case leading to re-do surgery. All the cases in our Unit were successfully completed, with complications mainly related to the original pathology rather than to the technique itself. CONCLUSIONS: The learning curve for Octoport use proved to be functional as for standard laparoscopy. In this study, surgical indications for the use of single port laparoscopy were defined, discerning favorable and unfavorable procedures. A proven superiority of this technique over traditional laparoscopy is yet to be defined, but Octoport has proved to be a safe and easy tool to reduce invasiveness of procedures in pediatric surgery with better cosmetic results.

Quality of Life and Anorectal Malformations: A Single-Center Experience.

Purpose: The treatment and long term clinical outcomes of anorectal malformations (ARM) in children have always been the focus of pediatric surgeons. This study aimed at reporting our experience as far as long-term follow-up of ARM in children is concern. Methods: We enrolled patients treated between 1999 and 2019, and established selection criteria to choose appropriate subjects. A validated questionnaire was used to determine long-term quality of life outcomes. Results: Out of a total of 48 patients treated within the study period, 28 were enrolled in this study. Among the latter, more than 35% had at least one long-time complication, and more than 90% had a good lifestyle. Urinary and fecal continence was achieved in more than 95% of the patients using medical devices. Conclusion: This study aimed to bring up new concepts; taking into consideration all aspects of life in patients with ARM, from school life to sexuality, while evaluating fecal and urinary continence. This is essential for the improvement of the skills of the different specialists involved in the management of these patients, and for the implementation of strategies that can improve postoperative function. Most especially, it will also help improve communication between doctors to ensure an adequate transition of these children into adult life.

Hypertrophic Pyloric Stenosis: 10 Years' Experience with Standard Open and Laparoscopic Approach.

PURPOSE: Hypertrophic pyloric stenosis (HPS) is the most common cause of gastric obstruction in newborns. Extra-mucosal pyloromyotomy can be performed through a small laparotomy or laparoscopy. The aim of this study was to compare the two surgical techniques. We also analyzed the incidence of HPS in infants in the last 10 years in relation to the demographic trend of our province. METHODS: We analyzed all the cases of HPS treated at our Unit between January 2010 and December 2019. The data were obtained from operating systems. Data about the demographic trends, in particular, the number of births and the population residing in the province of Verona from 2010 to 2019, were also retrieved. RESULTS: During the study period, 60 patients were treated for HPS and met the inclusion criteria. Of these, 56 males and 4 females with an average age of 38±14 days at surgery were included. No differences were found in terms of the duration of surgery, post-operative complications, duration of hospitalization, and weight at the time of surgery. The only statistically significant data was the chlorine level in cases with and without post-operative vomiting (97±3.5 vs. 102±3.3 mmol/L, p<0.05). There was a lower incidence of HPS from 2014 to 2019; however, there was no significant evidence regarding the correlation between this and the reduced birth rate recorded in the province of Verona during the same period. CONCLUSION: Although laparoscopic pyloromyotomy is a highly complex procedure, it is a feasible alternative to the classic open technique.

Prevalence and survival of patients with anorectal malformations: A population-based study.

BACKGROUND: Anorectal malformations (ARMs) are the most frequent congenital intestinal anomalies. The aim of this study was to describe the epidemiology of anorectal defects between 1981 and 2014 and to evaluate patients' survival. METHODS: A population-based study using data collected by an Italian, regional registry of birth defects and by the local Pediatric Surgery Units. RESULTS: A total of 428 individuals with ARM were identified, with an overall prevalence of 3.09 per 10,000 births. Characteristics associated with decreased survival were low birth weight (<2500 g) (HR 6.4; 95% CI, 2.3-17.9), the presence of two or more additional major defects (HR 7.9; 95% CI, 2.2-27.8), and birth before year 2000 (HR 4.7; 95% CI, 1.8-11.8). The 10-year survival probability was 100% for individuals with isolated ARM, regardless of their birth weight. Survival of patients with non-isolated ARM varied according to their year of birth and birth weight: 73.3% (≥2500 g) and 23.8% (<2500 g) in children born before 2000; 97.9% (≥2500 g) and 68.8% (<2500 g) in children born after year 2000. CONCLUSIONS: This study found a significant improvement in the survival of individuals with anorectal malformations over the past decades and identified the strongest predictors of mortality. LEVEL OF EVIDENCE (PROGNOSIS STUDY): Level II.

The Role of Sonoelastography in the Evaluation of Testes With Varicocele.

OBJECTIVE: To evaluate the role of elastosonography in the evaluation of testicular elasticity as a predictive sign of testicular damage in patients with varicocele. MATERIALS AND METHODS: Between December 2010 and December 2014, we evaluated patients with varicocele by sonoelastography (SE) of the testes. We created 3 groups: group A included patients with untreated varicocele; group B, patients treated with the same technique; and group C, healthy age-matched patients without varicocele. All patients underwent SE for the evaluation of testicular stiffness and results were graded from 1 to 3 following the color scale grading. RESULTS: During the study period, 36 boys (9-16 years old) with untreated varicocele, 47 treated patients, and 24 age-matched healthy subjects underwent control visit for varicocele and SE. All right testes of all groups were scored as 1, whereas testes with varicocele were stiffer than normal; all hypotrophies were scored as 3, whereas not all testes that were scored 3 were associated with testicular hypotrophy. There was a significant and statistical recovery rate of the testicular volume and the sonoelastographic score after surgery. CONCLUSION: Testes with varicocele are significantly stiffer than normal ones. All testes with testicular hypotrophy had grade 3 sonoelastographic scores, but not all patients with a grade 3 score have testicular hypotrophy or continuous spermatic vein reflux. Our results show that sonoelasography can play a significant role in the evaluation of testicular elasticity as a predictive sign of testicular damage.

Wandering spleen with a ten-time twisted vascular pedicle.

Torsion of a wandering spleen is a rare cause of acute abdomen in children, usually diagnosed with color-Doppler ultrasonography and enhanced computed tomography. We report a pediatric case of torsion of wandering spleen.

Neonatal surgery for giant floating abdominal cysts in females: clinical and surgical management.

OBJECTIVE: Abdominal cystic formations in neonates are rare entities and often diagnostic suspicion arises before birth as a result of routine ultrasonographic scans carried out during pregnancy. The aim of this study is to report the authors' experience with giant floating abdominal cysts in females. STUDY DESIGN: The cases of antenatal abdominal cysts in females detected on ultrasound at the Department of Antenatal Diagnosis (Azienda Ospedaliera Universitaria Integrata, Verona, Italy) of the authors' institution between May 2005 and May 2013 were recorded together with their clinical and surgical findings. RESULTS: 16 patients underwent surgery for a giant floating abdominal cyst 2 to 6 days after birth. Postnatal ultrasound and laparoscopic exploration were useful to identify an antenatal torsion of the ovarian-tube complex. All patients were treated with a laparoscopic approach using 3-mm ports after video-assisted percutaneous aspiration of the cyst. CONCLUSIONS: Giant abdominal cysts in female neonates should be treated immediately in order to avoid respiratory distress and complications. The laparoscopic approach is useful to confirm the diagnosis and to choose the most suitable treatment; giant floating abdominal cysts are closely correlated with torsion or autoamputation of the ovarian-tube complex.

Transumbilical laparoscopic-assisted appendectomy in children: Clinical and surgical outcomes.

The aim of this paper is to present and describe transumbilical laparoscopic-assisted appendectomy in children, focusing on its technical aspects and clinical and surgical outcomes. The surgical charts of all patients aged between 0 and 14 years treated with transumbilical laparoscopic-assisted appendectomy admitted to the authors' institution from January 2009 to September 2013 with a diagnosis of suspected appendicitis following clinical, laboratory and ultrasound findings were reviewed. Operating time, intraoperative findings, need for conversion or for additional trocars, and surgical complications were reported. During the study period, 120 patients aged between 6 and 14 years (mean age: 9.9 years), 73 females (61%) and 47 males (39%), were treated with transumbilical laparoscopic-assisted appendectomy. There were 37 cases of hyperemic appendicitis (subserosal and retrocecal), 74 cases of phlegmonous appendicitis and 9 cases of perforated gangrenous appendicitis. It was not possible to establish a correlation between grade of appendicitis and mean operating time (P > 0.05). Eleven cases (9%) needed the use of one additional trocar, while 8 patients (6%) required conversion to the standard laparoscopic technique with the use of two additional trocars. No patient was converted to the open technique. Transumbilical laparoscopic-assisted appendectomy is a safe technique in children and it could be used by surgeons who want to approach other minimally invasive techniques.

The role of transthoracic ultrasounds to assess patients with pectus excavatum.

INTRODUCTION: Pectus excavatum is the most common congenital malformation of the anterior chest wall. The purpose of this study is to assess the role of thoracic ultrasound studies in the preoperative workup of patients affected by pectus excavatum and to identify the dynamics of the chest wall. MATERIALS AND METHODS: An observational study was carried out between January and September 2011. Patients between 4 and 14 years of age were divided into 5 study groups. Group A: healthy patients without pectus excavatum; Group B: healthy patients with different grades of untreated pectus excavatum; Group C: patients with pectus excavatum treated with a Nuss bar; Group D: patients surgically treated with removed bar; Group E: patients surgically treated with different techniques. RESULTS: Patients with deeper anatomical depression showed a differential value between maximum inspiration and forced expiration lower than healthy patients or patients with shallower depression (p<0.05) in any age range considered. A depression deeper than 2.8 cm was associated with lower elasticity of the chest wall. CONCLUSIONS: Study results demonstrate that the ultrasound is useful in patients with PE. Patients with pectus excavatum have altered chest dynamics when compared to healthy patients. The study also demonstrate that between the 4th and the 6th ribs there is the great dynamicity of the chest wall.

Predictors of successful sexual partnering of adults with spina bifida.

PURPOSE: We assessed sexual education and function of adults with spina bifida to identify predictors of relationships and sexual activity. MATERIALS AND METHODS: A total of 290 patients with spina bifida were clustered into 6 groups based on lesion level, including men in group 1-less than L2, group 2-L3-L5 and group 3-less than S1, and women in group 4-greater than L2, group 5-L3-L5 and group 6-less than S1. Urinary continence, genital sensation and patient educational level were considered. A questionnaire on sexual education, relationship and sexual activity was administered. RESULTS: No difference in the incontinence rate was noted between males and females. Men had learned sex education from friends/media (41.6%) and women had learned it from parents (37.5%) or at school (33.7%). Genital sensation was normal in 7.2%, 53.3% and 53.5% of the patients in groups 1 to 3, respectively. Patients in group 3 had more frequent sexual intercourse than those in group 1 or 2 (30% vs 14.3% and 14.2%, respectively). Genital sensation was decreased in group 4 patients compared to those in groups 5 and 6 (44.4% vs 13% and 3.5%, respectively). Patients in group 4 were more sexually active than those in groups 5 and 6 (p <0.05). Lesion level did not affect the ability to form relationships in patients of either gender. Education level was the same across all patients with no difference when male/female groups were compared by lesion level. Predictors indicated that patients with the highest chance of finding a partner and engaging in sexual activity were those with the lowest lesion level. However, all other predictors were statistically significant (p <0.05). CONCLUSIONS: Sex counseling should be part of the regular medical care in patients with spina bifida. A difference exists between males and females when comparing lesion level and sexual activity.

Unusual presentation of antenatal ovarian torsion: free-floating abdominal cysts. Our experience and surgical management.

BACKGROUND: Abdominal cystic formations in newborns are relatively common and often diagnostic suspicion arises before birth as a result of ultrasound scans carried out during pregnancy. Prenatal ovarian torsion is a rare condition very difficult to manage in the first days of life. We report and discuss the management of prenatal ovarian torsion with a free-floating abdominal cyst detected on prenatal ultrasound. MATERIALS AND METHODS: We recorded the cases of antenatal abdominal cysts detected on ultrasound at the Department of Antenatal Diagnosis between January 2003 and January 2007. Only patients with a free-floating cyst were included in the study. Clinical and surgical findings were then recorded. RESULTS: Two out of 57 patients underwent surgery for a free-floating abdominal cyst during the second day of life. Postnatal ultrasound, Doppler ultrasound, and laparoscopic exploration were useful to identify an unusual presentation of antenatal ovarian torsion with a complete atresia of the Fallopian tube. CONCLUSIONS: The cases reported in this study suggest that a good clinical approach to all cases of abdominal cysts detected on prenatal ultrasound scans require postnatal Doppler and abdominal ultrasound with a laparoscopic exploration. Free-floating abdominal cysts are rare but, at the same time, strictly correlated with autoamputation of the ovary/Fallopian tube complex.
