RESUMO
Minimally invasive approach to the adrenal gland was first reported in 1992. Since then, the experience with the laparoscopic technique for adrenal disease in children has been limited. We report our experience with minimally invasive adrenal surgery in children. Two young girls (2 and 4 years old) with a left adrenal mass were operated using minimally invasive surgery (MIS) in our Unit. Ultrasonography and MRI showed in the oldest a 2 x 3 cm adrenal mass, while in the youngest a 5.5 x 5 cm adrenal tumor was found. According to the pre-existing literature, we approached the smallest lesion via retroperitoneoscopy, and the largest one laparoscopically. The operating time was 110 minutes for retroperitoneoscopy and 75 minutes for laparoscopy. No major intra or postoperative complications occurred. There were no conversions to open surgery. Postoperative hospital stay was 5 days for both patients. In both cases, the anatomo-pathological result was an adenoma. Minimally invasive adrenalectomy is a safe and feasible procedure in children with good results. For lesions smaller than 3-4 cm retroperitonescopy is feasible, while for tumors larger than 5 cm, due to malignancy risk, the laparoscopic approach is indicated. To keep oncologic criteria it is important to avoid tumor rupture and to extract the specimen in an endobag.

AIM: The aim of study was to retrospectively analyze our series of total and partial retroperiotoneoscopic nephrectomies performed in the last 5 years. METHODS: Twenty-two procedures were performed, 20 patients underwent nephrectomy and 2 patients underwent partial nephrectomy. The 20 patients who underwent nephrectomy were divided in 2 groups: group 1 (G1) patients-1-10, for whom we performed the procedure using monopolar coagulation, and group 2 (G2) patients 11-20 for whom we used a new hemostatic device to perform dissection and hemostasis. The results were analyzed using χ2 test. The results of partial nephrectomies were analyzed separately. RESULTS: No conversion were reported. We analyzed 6 parameters to compare the results: operative time (OT), estimated blood loss (EBL), need for transfusion (NT), complications, time to oral intake (TOI), hospital stay (HS). OT in G1 was in median 85 minutes, in G2 65 minutes (P=0.004); EBL was 15 mL for G1 and 5 mL for G2 (P=0.000.), NT was not necessary in both, in G1 we had 2 complications and 1 complication in G2; TOI was day 1 for both groups; median HS was 3 days for both. As for heminephrectomy, OT was 120 and 140 min, EBL 30 mL in both, NT not necessary, TOI was 1 day and HS 4 and 5 days respectively. CONCLUSION: Our study shows that the use of a new hemostatic devices reduce significantly OT and EBL in children underwent renal ablative surgery for benign pathologies compared with the use of monopolar coagulation.

BACKGROUND: Feeding difficulties and gastroesophageal reflux (GER) are major problems in severely neurologically impaired children. Many patients are managed with a simple gastrostomy, with or without fundoplication. Unfortunately, fundoplication and gastrostomy are not devoid of complications, indicating the need for other options in the management of these patients. METHODS: Between January 2002 and June 2010, ten patients (age range, 18 months-14 years) have been treated by creating a jejunostomy with the laparoscopic-assisted procedure. The procedure was performed using 2-3 trocars. The technique consists of identifying the first jeujnal loop, grasping it 20-30 cm away from the Treitz ligament, and exteriorizing it to the trocar orifice under visual guide. The jejunostomy was created outside the abdominal cavity during open surgery. At the end of the jejunostomy, the correct position of the intestinal loops was evaluated via laparoscopy. RESULTS: Surgery lasted 40 min on average, the laparoscopic portion about 10 min. Hospital stay was 3 or 7 days for all patients. At the longest follow-up (8 years), all patients had experienced a significant weight gain. One patient died 1 year after the procedure of unknown causes. As for the other complications: 4/10 patients experienced peristomal heritema, 2/10 device's dislocation and 1 patient a peristomal granuloma. CONCLUSIONS: Laparoscopic-assisted jejunostomy is a safe and effective procedure to adopt in neurologically impaired children with feeding problems and GER. We advocate the use of this procedure in neurologically impaired patients with feeding problems and reflux due to its overall practicability and because there is minimal surgical trauma. The improvement in the quality of life of these children after the jejunostomy seems to be the major advantage of this procedure. However the management of jejunostomy can be difficult for parents above all in the first postoperative months.

The management of the contralateral region in a child with a known unilateral inguinal hernia is a debated issue among paediatric surgeons. The available literature indicates that the perspective of the child's parents is seldom. This study was performed to evaluate parents' views on this topic. After the Ethical Committee's approval, 100 consecutive patients under 12 years of age with a unilateral inguinal hernia were studied prospectively from March 2010 to September 2010. After an oral interview, a study form was given to the parents about the nature of an inguinal hernia, the incidence of 20 to 90% of a contralateral patency of the peritoneal-vaginal duct and the possible surgical options (inguinal repair or laparoscopic repair). The parents' decision and surgical results were analyzed. Eighty-nine parents chose laparoscopic approach, and 11 parents preferred inguinal exploration. Regarding their motives, all 89 parents requesting laparoscopic approach indicated that the convenience and risk to have a second anaesthesia was the primary reason of their decision. The 11 parents who preferred inguinal approach indicated that the fear of a new surgical technology was their primary reason. Conclusion There is no consensus about the management of paediatric patients with a unilateral inguinal hernia. We believe that a correct decision-making strategy for parents' choice is to propose them the both procedures. Our study shows that parents prefer laparoscopic inspection and repair in the vast majority of cases.

Meckel's diverticulum has varied presentations in children and often becomes a diagnostic challenge. The authors present a 10-year-old boy with abdominal pain and one episode of melena. His symptoms were undervalued during two previous hospitalizations in pediatric units until his hemoglobin level dropped from 8.2 to 3.5 g/dL. The laparoscopic intervention performed in emergency identified a bleeding Meckel's diverticulum that was resected after being exteriorized from the umbilicus. Our observation shows that severe hemorrhage due to a Meckel's diverticulum is possible albeit exceptional.

UNLABELLED: The blue rubber bleb nevus syndrome or Bean syndrome is a rare disorder characterized by cutaneous and gastrointestinal vascular malformations. A 5-year-old girl with Bean syndrome hospitalized in a pediatric unit came under our observation with abdominal pain and vomiting. An X-ray of the abdomen showed an intestinal occlusion and an ultrasonography showed a suspected intestinal invagination. She underwent emergency laparoscopic surgery using three trocars. Laparoscopy revealed a huge ascitis and multiple vascular lesions located on the loops and on the parietal peritoneum, and we identified also an ileo-ileal invagination. We performed a laparoscopic disinvagination that showed one huge vascular lesion producing the invagination and causing a stenosis of intestinal lumen. We performed an intestinal resection after exteriorizing the loops through the umbilicus as well as a termino-terminal ileal anastomosis. CONCLUSIONS: Our case shows that an intestinal invagination due to Bean syndrome is extremely rare in pediatric patients but possible. In the emergency, laparoscopy seems to be a safe and effective procedure to confirm the diagnosis and to perform the disinvagination mini-invasivally. In addition, laparoscopy permits to have a clear picture of other intra-abdominal lesions linked to Bean syndrome.

PURPOSE: This retrospective study aims to evaluate the feasibility, safety and complication rate of laparoscopic inguinal hernia repair for small babies weighing 3 kg or less. METHODS: A retrospective analysis was performed on the surgical charts of 67 infants (47 boys and 20 girls) weighing 3 kg or less who underwent laparoscopic hernia repair in a 3-year period. A regular 5-mm scope was used for visualization, and 2 or 3-mm instruments were used for the closure of the inner inguinal ring using 3/0 non-absorbable suture. The median weight at surgery was 2,600 g (range 1,450-3,000 g). All except three were premature. RESULTS: Of the 67 infants, 15 (22.3 %) presented with an irreducible hernia. In three cases of irreducible hernias, we also performed a transumbilical appendectomy at the end of the hernia repair. Minor problems related with anesthesia were noted in four cases. Hernia recurrence was observed in three patients (4.4 %). No cases of testicular atrophy occurred. In 10 boys, we observed 12 cases of high testes, only 4 testes requiring subsequent orchiopexy. CONCLUSIONS: Laparoscopic inguinal hernia repair for babies weighing 3 kg or less is feasible, safe and perhaps even less technically demanding than open inguinal herniotomy.

PURPOSE: We reviewed the records of 36 pediatric patients operated on between 1990 and 1997 for high intra-abdominal testes, using the 2-step Fowler-Stephens procedure via laparoscopy. MATERIALS AND METHODS: Patients were followed for 10 to 17 years. Three patients who had undergone the second stage by open procedure were excluded from study. The 33 remaining patients were contacted by telephone, and 12 (7 with right and 5 with left intra-abdominal testes) agreed to undergo clinical and instrumental examination. Patient age ranged from 13 to 26 years (average 14.7). All patients underwent clinical examination and volumetric measurement of both testes using color Doppler ultrasound. RESULTS: Two of the 12 patients (16.7%) had an atrophic testis in the scrotum and 10 (83.3%) had a viable testis in the scrotum. The operated testis was always smaller than the normal testis, despite the good vascularization detected on echo color Doppler ultrasound. One patient had ultrasound evidence of bilateral microcalcifications with normal vascularization. Mann-Whitney test showed there was a statistically significant difference between the volume of the operated testis and the normal testis. CONCLUSIONS: It is extremely difficult to perform studies on the long-term outcome of surgical procedures. We describe the outcome at more than 10 years postoperatively, and demonstrate that greater than 83% of patients who underwent a 2-step Fowler-Stephens procedure using laparoscopy had satisfactory results. The operated testis was always significantly smaller compared to the normal testis but was well vascularized.

BACKGROUND: Few reports have elucidated the role of minimally invasive surgery (MIS) for pediatric malignancies. This study aimed to review the results of a multicenter study on the management of thoracic tumors in children using MIS. METHODS: A 5-year retrospective review of all MIS procedures for the treatment of pediatric malignancies performed in seven centers belonging to the Italian Society of Videosurgey in Infancy is reported. The data from 145 pediatric oncologic patients (80 girls and 65 boys) ages 30 days to 17 years (median, 7.2 years) were analyzed. Of the procedures performed, 87 were laparoscopies (60%), 55 were thoracoscopies (38%), and 3 were lumboscopies (2%). This study focused only on the results of the 55 thoracoscopic procedures performed for diagnostic purposes in 19 cases (34.6%) and for therapeutic purposes in 36 cases (65.4%). RESULTS: The duration of surgery was 15 to 180 min (median, 65 min). Metastasectomies were performed for various etiologies in 31 of the 55 cases. Of the 55 patients, 5 underwent resection of a mediastinal tumor, and 19 underwent a diagnostic thoracoscopy. During a mean follow-up period of 25.6 months, 2 (3.6%) of the 55 patients experienced perioperative complications. CONCLUSIONS: The role of MIS in tumor resection for children is currently limited, but may be used in individual cases when the preoperative workup shows it to be feasible. Its indication is strictly dependent on the thoracoscopic experience of the surgeon and the tumor site for preoperative imaging techniques. When the indication for thoracoscopy is correct, this approach has high therapeutic applicability (65.4% in our series). Our preliminary experience shows that careful patient selection and an appropriate level of technical skill make thoracoscopy a reasonable and safe option for the treatment of pediatric malignancies.

BACKGROUND: Nissen fundoplication is the most popular laparoscopic operation for the management of gastroesophageal reflux disease (GERD). Partial fundoplications seem to be associated with a lower incidence of postoperative dysphagia, and thus a better quality of life for patients. The aim of this study was to compare the long-term outcome in neurologically normal children who underwent laparoscopic Nissen, Toupet, or Thal procedures in three European centers with a large experience in laparoscopic antireflux procedures. METHODS: This study retrospectively analyzed the data of 300 consecutive patients with GERD who underwent laparoscopic surgery. The first 100 cases were recorded for each team, with the first team using the Toupet, the second team using the Thal, and the third team using the Nissen procedure. The only exclusion criteria for this study was neurologic impairment. For this reason, 66 neurologically impaired children (52 Thal, 10 Nissen, 4 Toupet) were excluded from the study. This evaluation focuses on the data for the remaining 238 neurologically normal children. The patients varied in age from 5 months to 16 years (median, 58 months). The median weight was 20 kg. All the children underwent a complete preoperative workup, and all had well-documented GERD. The position of the trocars and the dissection phase were similar in all the procedures, as was the posterior approximation of the crura. The short gastric vessels were divided in only six patients (2.5%). The only difference in the surgical procedures was the type of antireflux valve created. RESULTS: The median duration of surgery was 70 min. There was no mortality and no conversion in this series. A total of 12 (5%) intraoperative complications (5 Nissen, 5 Toupet, 2 Thal) and 13 (5.4%) postoperative complications (3 Toupet, 4 Nissen, 6 Thal) were recorded. Only six (2.5%) redo procedures (2 Thal, 2 Toupet, 2 Nissen) were performed. After a minimum follow-up period of 5 years, all the children were free of symptoms except nine (3.7%), who sometimes still require medication. The incidence of complications and redo surgery for the three procedures analyzed with the Mann-Whitney U test are not statistically significant. CONCLUSIONS: For pediatric patients with GERD, laparoscopic Nissen, Toupet, and Thal antireflux procedures yielded satisfactory results, and none of the approaches led to increased dysphagia. The 5% rate for intraoperative complications seems linked to the learning curve period. The authors consider the three procedures as extremely effective for the treatment of children with GERD, and they believe that the choice of one procedure over the other depends only on the surgeon's experience. Parental satisfaction with laparoscopic treatment was very high in all the three series.

BACKGROUND: The terms megaureter or hydroureteronephrosis are non-specific because indicate various pathologic entities recognise different causes (obstruction, reflux, obstruction-reflux, primary and secondary). An undeveloped renal function in neonatal period makes more difficult the therapeutic approach. Actually the problem is to find the indicators that consent us the individualization of patients more suitable for nonoperative management. METHODS: From 1996 to 2002, we observed 60 patients with 74 megaureters. In 24 cases the diagnosis was antenatal, 6 cases were diagnosed immediately after birth, 13 in the first year of life and 17 after the first year (2y-10y). Patients were classified in two groups based on age; 43 cases diagnosed in the first year of life and 17 after. Both of them were classified in two further groups based on ureteral size and renal function, scintigraphically evaluated. RESULTS: In the first group (A) ureters with 10 mm of dilatation improved in 38.9% of the cases. Were stationary 50% and impaired 11,1% of them. Ureters with dilatation between 7 and 10 mm improved in 24%, were stationary in 72% and impaired in in 4% of the cases. Ureters with less than 7mm dilatation improved in 35.2% and were stationary in 64.8%. In the group A renal scintigraphy MAG3 demonstrated, in the patients with acceptable renal function and washout, an improvement in 65% of the cases. Was stationary in 30% and impaired in 10%. CONCLUSIONS: The grade of dilatation evaluated with ultrasonographic exam and the study of renal function with diuresis renal scintigraphy using Tc-99m MAG3 and washout grade with diuresis renal scintigraphy are remarkable markers for the treatment choice.

BACKGROUND: Feeding difficulties and gastroesophageal reflux (GER) are major problems in severely neurologically impaired children. Many patients are managed with a simple gastrostomy, with or without fundoplication. Unfortunately, fundoplication and gastrostomy are not devoid of complications, indicating the need for other options in the management of these patients. METHODS: Since January 2002, seven patients (age range, 5-14 years) have been treated by creating a jejunostomy with the laparoscopic-assisted procedure. The procedure was performed using two 10-mm trocars. The technique consists of identifying the first jejunal loop, grasping it 20-30 cm away from the Treitz ligament with fenestrated atraumatic forceps, and exteriorizing it to the trocar orifice under visual guide. The jejunostomy was created outside the abdominal cavity during open surgery. At the end of the jejunostomy, the correct positions of the intestinal loop and feeding tube were evaluated via laparoscopy. RESULTS: Surgery lasted 40 min on average, the laparoscopic portion only 5 min. There were no perioperative complications; hospital stay was 3 or 4 days for all patients. At the longest follow-up (18 months), all patients had experienced a significant weight gain, with a high level of parental satisfaction. One patient died 1 year after the procedure of unknown causes. All the others are well, without complications or problems, and their parents are extremely satisfied with the improved quality of life of their children. CONCLUSIONS: Laparoscopic-assisted jejunostomy is a safe and effective procedure to adopt in neurologically impaired children with feeding problems and GER. This procedure solves these patients' feeding problems even if the reflux is not completely eliminated. We advocate the use of this procedure in neurologically impaired patients with feeding problems and reflux due to its overall practicability and because there is minimal surgical trauma. This technique is extremely safe because the surgeon is able to verify, at the end of procedure, the status of the jejunostomy from outside and inside the abdominal cavity. The improvement in the quality of life of these children after the jejunostomy seems to be the major advantage of this procedure.

In this paper, the quasinormal mode (QNM) theory is applied to discuss the quantum problem of an atom embedded inside a one-dimensional (1D) photonic band gap (PBG) cavity pumped by two counterpropagating laser beams. The e.m. field is quantized in terms of the QNMs in the 1D PBG and the atom modeled as a two-level system is assumed to be weakly coupled to just one of the QNMs. The main result of the paper is that the decay time depends on the position of the dipole inside the cavity, and can be controlled by the phase difference of the two laser beams.
RESUMO
One of the main advantages of laparoscopy in children is the fact that it enables a magnified view and the possibility to explore the whole abdominal cavity. This case report clearly shows these advantages. We report the case of a 3-yr-old girl, suffering from severe GERD and right inguinal inguinal hernia, who had already been operated at birth for esophageal atresia. We performed a laparoscopic fundoplication according to Nissen and, at the end of procedure, we decided to turn the optic down to control the right inguinal region to confirm the presence of an inguinal hernia. To our great surprise we found a right oblique external hernia as well as a direct inguinal hernia on the same side. Both hernias was treated successfully in laparoscopy. At a 1-year follow-up, the patient presented no reflux and no recurrence of the inguinal hernias. The laparoscopy in this case permitted operation on two different pathologies involving the upper and lower parts of the abdominal cavity using the same ports and without enlarging the incision, as would happen in laparotomy. The main relevance of this case is that laparoscopy allowed the detection of an associated pathology like a direct inguinal hernia that would have been certainly overlooked in open surgery and could have caused a recurrent hernia if operated via open surgery.

Usually the word conversion implies conversion from a laparoscopic procedure to an open procedure to solve complications occurring during laparoscopy. In this article we report a conversion from an open procedure to a laparoscopic one, to treat a vascular complication that occurred during an orchiectomy performed in open surgery. A 2-year-old boy came to our center for a right orchiectomy. The clinical history of this baby showed the presence of a right atrophic testis positioned in the medial part of the inguinal canal, a finding also confirmed by ultrasonography. One of our residents performed a right orchiectomy via an open inguinal procedure. After removing the testis, and before ligating the inner spermatic vessels at the level of the internal inguinal ring, the forceps that held the vessels was inadvertently opened, causing a contraction of the spermatic vessels. Since we were unable to identify the vessels and achieve hemostasis via the inguinal opening, a conversion to laparoscopic surgery was decided. A 10-mm 0 degrees optics was introduced through an umbilical trocar and revealed a large retroperitoneal hematoma along both the inner spermatic vessels and the deferential vessels, for about 3-4 cm from the internal inguinal ring. Two 5-mm trocars were positioned in triangulation and hemostasis was achieved by positioning clips on the vessels at the level of internal inguinal ring and proximally to the hematoma. Surgery lasted 1 hour; the laparoscopic procedure, 25 minutes. The baby was discharged 2 days after surgery. At a 9-month follow-up the clinical and ultrasonographical evaluation was normal. This case clearly shows the usefulness of laparoscopy in pediatric surgery, as well as to solve complications due to open surgery. We think that nowadays the use of laparoscopy should be considered indispensable by every pediatric surgical team.

Pyriform sinus fistula is a very rare branchial apparatus malformation, often appearing in the form of a cervical inflammatory process (abscess or suppurative thyroiditis), especially in infants. Failure to diagnose this lesion may result in unexpected recurrence. A case of recurrent suppurative thyroiditis caused by pyriform sinus fistula in a 9-year-old girl is reported. In the latency period of infection, the fistula tract was identified by a barium meal contrast study. Direct endoscopy showed the fistula internal orifice at the apex of the left pyriform fossa. The fistula was completely obliterated by injection of fibrin glue. Suppurative thyroiditis is reported mainly in the pediatric literature, and the reported case is the first to be managed endoscopically by injection of fibrin adhesive.

BACKGROUND: The purpose of our study was to evaluate the results and complications of laparoscopic cholecystectomy in a case series of 110 infants. METHODS: Over a 5-year period (1993-98), we performed laparoscopic cholecystectomy in 110 pediatric patients. Surgery was performed at different institutions by three different surgeons. The patient population was composed of 69 girls and 41 boys; their ages ranged from 1 to 16 years (median, 8.5). All of the 110 children had symptomatic cholelithiasis, which was confirmed at ultrasound examination. An associated pathology was present in 27 patients (sickle cell disease in 17 cases, hereditary spherocytosis in seven cases, thalassemia in three); the other 83 infants were affected by idiopathic cholelithiasis. In 107 patients, the operation was performed using four ports; in three patients, it was done using five ports. In three patients, we also performed a concomitant splenectomy. RESULTS: Median duration of simple cholecystectomy was 45 min (range, 25-75) and hospital stay ranged from 1 to 10 days (median, 2). Only 15 children required drainage. We had 17 complications in our series (15.5%), including a gallbladder perforation during dissection in 11 patients, a fall of stones into the abdominal cavity during extraction in one patient, and a trocar orifice infection in the postoperative period in five patients. At a maximum follow-up of five years (range, 1-5), all patients were doing well. CONCLUSION: Laparoscopic cholecystectomy in children seems to be as effective as open surgery in cases of symptomatic cholelithiasis. In pediatric patients more than in adults, an accurate and precise dissection and a sound knowledge of possible congenital biliary abnormalities are essential to avoid any kind of complication.

BACKGROUND: The aim of this paper is to show the efficacy of laparoscopy using only one umbilical trocar to treat abdominal complications of hydrocephalic children with ventriculoperitoneal shunts (VPS). MATERIALS AND METHODS: In a 15-year period, 14 laparoscopies were performed on as many children with VPS complications: in the last 4 patients only one trocar was used to solve the complications, and this subgroup will be the object of the present study. Concerning the indication for surgery, the patients presented one catheter lost in the abdominal cavity; one cerebrospinal fluid pseudocysts; one bowel obstruction; and one malfunctioning peritoneal limbs of the catheter. We used the one-trocar laparoscopic approach in all the 4 patients, and the 10-mm trocar was always introduced through the umbilical orifice in open laparoscopy. RESULTS: The laparoscopic technique was curative in all four cases and permitted the solution of the complication. CONCLUSIONS: One-trocar laparoscopic surgery can be considered as the ideal procedure in case of abdominal complications of VPS in children with hydrocephalus.

BACKGROUND: Due to technological improvements, the use of tissue adhesives and glues for tissue approximation and hemostasis in surgery has increased. We report our preliminary experience with this technology in pediatric endosurgery. METHODS: Between 1997 and 2000, we employed tissue adhesives in 48 pediatric patients during laparoscopic procedures. In 25 patients, the glue was adopted for the hemostasis of parenchimal organs (liver in 24 cases and spleen in one). In three cases, the glue was used to repair organ perforation, in 19 it was used to close the distal part of a patent processus vaginalis in case of congenital inguinal hernia. In the final case, the glue was adopted to achieve optimal airtightness in case of pulmonary biopsy. The glue was injected with the aid of a needle positioned transparietally. RESULTS: The procedure was easy and rapid in all cases, and there were no problems or complications related to glue positioning at a mean follow up of 51 months. CONCLUSION: Tissue adhesives are a very versatile product for use in pediatric laparoscopic surgery. It is likely that their usage will increase as the technology improves and more effective products are developed.
