ABSTRACT

We report our experience with a sutureless technique for laparoscopic inguinal hernia repair in children. Twenty-eight children, 12 girls and 16 boys, aged 3 months to 7 years, underwent sutureless laparoscopic inguinal hernia repair. In girls, we utilized simple cauterization of the internal inguinal ring with a single trocar technique. In boys denudation of the peritoneum was obtained utilizing a three-trocar technique. The peritoneum around the internal inguinal ring was peeled off and detached from the vas and the vessels, and then wrapped around the grasper, resulting in a large area of denudation. No perioperative complications were observed. No recurrences nor testicular damage were noted after a mean follow-up of 18 months (range 6-35 months). The mean operative time was 12 min (range 7-20 min) for girls and 19 min (range 15-30 min) for boys. A 6-year-old girl exhibited a lymphocele. The sutureless technique appears to be easy, safe, and effective, provided that the patients are carefully selected. In boys, special attention needs to be paid to preservation of the vas and the testicular vessels.

ABSTRACT

Simple renal cysts, although common in adults, are rare in children. They are usually discovered incidentally in the course of the study of other urinary tract symptoms, although they are not always asymptomatic. Renal cysts can be classified as being either simple or complex. The purpose of this review is to present our case series of simple symptomatic renal cysts treated with laparoscopy. Nineteen patients with symptomatic renal cysts (6 to 13.5 cm) were referred to our institution between January 2006 and January 2017. They comprised 12 (40.5%) females and seven (59.5%) males, aged 8 to 15, with a mean age of 12.2 years. Of these patients, nine had previously been treated unsuccessfully by ultrasound-guided aspiration/alcoholization with 95%-ethanol, between 9 and 13 months prior to the laparoscopy. Five patients had undergone one treatment and four had undergone two treatments. All of the patients were treated by laparoscopic threetrocar deroofing. The cysts were opened and the wall excised using scissors and a monopolar hook. In most cases, to better handle the edges of the cyst and obtain a better grip, a needle was used to aspirate a small amount of fluid (used for cytological examination). The wall of the cyst was excised, the cyst edges were sealed, and the perirenal fat was placed on the bottom of the cyst (wadding technique). The mean operating time was 95 minutes (range 50- 150). The postoperative course was uneventful for all of the patients. The hospital stay ranged from one to three days. All of the patients were asymptomatic following the treatment. At a mean follow-up time of 3.6 years, none of the patients had experienced a recurrence. Renal function, as assessed by a MAG3 renal scintigraphy scan, was well-preserved in all of the patients, and all of them undergo an annual ultrasound scan.

ABSTRACT

The aim of this study was to verify the validity, feasibility, and the functional results, by uroflowmetry, of Tubularized proximallyincised plate technique in selected case of distal/midshaft hypospadias. Out of 120 patients scheduled to undergo TIP (or Snodgrass) procedure, 23 were selected between January 2013 and January 2016 (19.1%). This case series comprised 16 patients with distal and 7 with midshaft hypospadias. Mean age at surgery was 2.9 years. The inclusion criteria were a deep and wide glandular groove and a proximal narrow urethral plate. The procedure was carried out as described by Snodgrass but the incision of the urethral plate, including the mucosal and submucosal tissue, was made only proximally, between the original meatus and the glandular groove in no case extending to the entire length of the plate. Postoperatively a foley catheter was left in place from 4 to 7 days. Uroflowmetry was performed when the patients age ranged from 2.5 to 5.7 years (mean age 3.11 years and mean follow-up 1.8 years, body surface 2). No patient presented fistulas nor perioperative complications. At uroflowmetry, eighteen patients presented values above the 25th percentile and 5 showed a borderline flow. All patients in this group remained stable without urinary symptoms. In selected cases, the tubularized proximally-incised plate yields satisfactory cosmetic and functional results for the treatment of midshaft proximal hypospadias. A long-term follow-up study is needed for further evaluation. Patient selection is crucial for the success of this technique.

ABSTRACT

BACKGROUND: The closure of a cystic duct during cholecystectomy by means of radiofrequency is still controversial. We report our preliminary experimental results with the use of LigaSure™ on common bile duct in rats. METHODS: Thirty Wistar rats weighing 70 to 120 g were employed for this study. The animals were all anesthetized with intraperitoneal ketamine and then divided into three groups. The first group (10 rats, Group C) underwent only laparotomy and isolation of the common bile duct. The second (10 rats, Group M) underwent laparotomy and closure of the common bile duct (CBD) with monopolar coagulation. The third group (10 rats, Group L) underwent laparotomy and sealing of the common bile duct with two application of LigaSureTM. Afterwards, all rats were kept in comfortable cages and were administered dibenzamine for five days. They were all sacrificed on day 20. Through a laparotomy, the liver and bile duct were removed for histological examination. Blood samples were obtained to dose bilirubin, amylase and transaminase levels. RESULTS: Mortality rate was 0 in the control group (C), 3/10 rats in group M and 0 in group L. In group L, the macroscopic examination showed a large choledochocele (3-3.5 × 1.5 cm) with few adhesions. At the histological examination there was optimal sealing of the common bile duct in 9/10 rats. In group M, 2/10 rats had liver abscesses, 3/10 rats had choledochocele and 5/10 rats, biliary peritonitis. There was intense tissue inflammation and the dissection was difficult. Analyses of blood samples showed an increase in total bilirubin, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in groups M and L. CONCLUSIONS: The preliminary results of our study confirm that radiofrequency can be safely used for the closure of the common bile duct. The choledochocele obtained with this technique could represent a good experimental model. These results could be a further step for using the LigaSureTM in clipless cholecystectomy.

ABSTRACT

Introduction Testicular microlithiasis (TM), characterized by the presence of intratubular calcifications in a single or both the gonads, is an uncommon entity with unknown etiology and outcome in pediatric and adolescent age. In this study, the results of a multicenter long-term survey are presented. Materials and Methods From 11 units of pediatric urology/surgery, patients with TM were identified and yearly, followed up in a 7-year period, adopting a specific database. The recorded items were: age at diagnosis, presenting symptoms/associated abnormalities, ultrasonographic finding, surgery and histology at biopsy, if performed. Results Out of 85 patients, 81 were evaluated yearly (4 patients lost to follow-up). TM was bilateral in 66.6% of the patients. Associate genital abnormalities were present in 90%, more frequently undescended/retractile testis (23.4%) and varicocele (22.2%). TM remained unchanged at 4.7 years follow-up in 77 patients (93.8%) and was reduced in 4 patients after 1 to 5 years of inguinoscrotal surgery. Orchiectomy was performed in three patients (3.7%), one for severe testicular hypoplasia and two for seminoma (2.5%), respectively, concurrent and metachronous to diagnosis of TM. Tumorectomy with parenchymal sparing surgery was performed in a teratoma associated with TM. Conclusion TM is a controversial entity, often associated with several inguinogenital features, which rarely can recover. Testicular malignancy, although present in TM, has not proven definitively associated to microliths. Proper counseling, yearly ultrasound, and self-examination are long-term recommended.

ABSTRACT

Introduction The objective of this study was to report on the use of vesicoscopy in the treatment of symptomatic congenital bladder diverticula (CBD) in children. Material and Methods In this study, 16 males, aged 4 to 12 years (median age, 6.25 years), were treated for symptomatic CBD; 3 patients presented double diverticulum and 13 presented single diverticulum. The presenting symptoms were recurrent urinary tract infection, hematuria, lower abdominal pain, and voiding dysfunctions as urgency, frequency alone, or in association. A first midline 5-mm trocar was introduced for a 0-degree telescope at the dome of the bladder, and two left and right 3- or 5-mm trocars were inserted through the anterolateral wall. The bladder was then insufflated with carbon dioxide to 10 to 12 mm Hg pressure. The diverticula were inverted into the bladder and the mucosa around the neck was circumcised by using scissors and hook. The defect was sutured and the bladder was drained. Vesicoureteral reflux (VUR) of third grade or higher was treated endoscopically. Results Mean operative time was 90 minutes for procedures. At 6-month follow-up, ultrasound and voiding cystourethrogram (VCUG) showed the disappearance of the diverticulum in 15 out of the 16 patients. The patient, with huge double diverticulum and fourth grade right VUR, presented recurrence of a small left diverticulum. Patients with voiding disorders presented a gradual improvement of their urgency. VUR disappeared at VCUG in all patients. Conclusion Vesicoscopic diverticulectomy resulted a safe and effective procedure and can be considered a valid alternative to the open or laparoscopic procedures. In our opinion, routine use of vesicoscopy could become the gold standard for the treatment of CBD in children.

ABSTRACT

BACKGROUND: Minimally invasive surgery is the current approach to perform heminephroureterectomy (HN) in children. This can be obtained through a transperitoneal (TP) or a retroperitoneal approach. Here, we report our experience using a TP approach. MATERIALS AND METHODS: From 2005 to 2014, 22 TP laparoscopic upper poles HN were performed at our institution. There were nine girls and 13 boys aged between 20 months and 6 years (mean age 3.9). Eight patients were diagnosed prenatally, 17 patients presented with urinary tract infection (UTI) and three with vomiting and failure to thrive. The indication for HN was reflux nephropathy and UTI in non-functioning upper pole in 19 patients and cystic dysplasia in 1 patient. The surgical technique involved the following steps: Cystoscopic recognition; positioning of 3-4 trocar (right HN); identification of the kidney (detachment of the colon); isolation and low ligation of the dilated ureter; decrossing from renal vessels; section of the parenchyma by LigaSure; haemostasis with clips and LigaSure; drain. RESULTS: The mean operative time was 154 min (range: 81-220 min). All patients were discharged from the 2 nd to 4 th day. Neither major complication nor conversion was recorded. 1 patient presented leakage of urine for 7 days from the drainage which resolved spontaneously. At ultrasound follow-up, 5 patients showed a secondary perirenal cyst, 2-5 cm diameter that resolved spontaneously. CONCLUSION: The results indicate that laparoscopic upper pole heminephrectomy is the treatment of choice in cases of non-functioning dilated lower segments of duplicated kidneys. The use of laparoscopic approach offers a good working space, a good visual control of the vessels and allows a very low isolation of the ureteral stump which counterbalance the peritoneal violation.

ABSTRACT

BACKGROUND: Single-incision laparoscopic surgery (SILS) has gained great popularity in paediatric surgery due to its minimally invasive approach and improved cosmetic results. Notwithstanding, reports describing its adoption in children are still fragmentary and some perplexities have been raised by some surgeons. We reviewed our experience with the SILS Palomo varicocelectomy procedure (SIL-V) in children and adolescents, comparing this group with a similar series operated using conventional laparoscopic varicocelectomy (CL-V). PATIENTS AND METHODS: A total of 69 Palomo laparoscopic varicocelectomies were performed in patients aged 11-17 years from January 2011 to January 2013. Indications for surgery included grades II-III varicocele or ipsilateral testicular hypotrophy. The SIL-V procedure was performed in 44 patients with roticulating and conventional 5 mm instruments. Testicular vessels were isolated "en bloc," clipped and cut. Operating time, visual analogue scale and post-operative results were compared to a similar group of 25 patients operated with CL-V. RESULTS: No patient of the SIL-V group required conversion to conventional laparoscopy, none to open surgery. Mean operative time was 22 min (range: 19-28) in the SIL-V group, not significantly different compared with CL-V (mean 21 min, range: 18-25). All patients experienced a smooth recovery from surgery without any complications, and were discharged on day 1. No difficulties were found in the SIL-V group. The post-operative pain score was significantly better in SIL-V. CONCLUSION: The SIL-V procedure is safe and effective and allows a fast and efficient isolation of the vascular bundle. The use of conventional instruments is technically feasible in SIL-V.

ABSTRACT

AIMS: The laparoscopic "Spaghetti Maneuver" consists in holding an organ by its extremity with a grasper and rolling it up around the tool to keep the organ stable and facilitate its traction within a small space. We describe our experience with the "Spaghetti Maneuver" in some minimally invasive procedures. MATERIALS AND METHODS: We successfully adopted this technique in 13 patients (5F : 8M) aged between 6 and 14 years (average age, 10) on whom we performed 7 appendectomies, 2 ureteral reimplantation and 4 cholecystectomies. In all cases, after the first steps, the appendix, the gallbladder and the ureter were rolled around the grasper and easily isolated; hemostasis was thus induced and the organ was mobilized until removal during cholecystectomy and appendectomy, and before the reimplantation in case of ureteral reimplantation. RESULTS: We found that this technique facilitated significantly the acts of holding, isolating and removing, when necessary, the structures involved, which remained constantly within the visual field of the operator. This allowed a very ergonomic work setting, overcoming the problem of the "blind" zone, which represents a dangerous and invisible area out of the operator's control during laparoscopy. Moreover the isolation maneuvers resulted easier and reduced operating time. CONCLUSION: We think that this technique is easy to perform and very useful, because it facilitates the dissection of these organs, by harmonizing and stabilizing the force of traction exercised.
