Abdominal lymphangiomas in children: interest of the laparoscopic approach.

BACKGROUND: Lymphangiomas are rare benign lesions of the lymphatic system. The most common symptoms are abdominal tumor or "acute abdomen" in children. The treatment of choice is complete surgical resection, but the recurrence rate with incomplete resection is high, and laparotomy exposes the patient to adhesions. The authors report their experience with the lymphangioma laparoscopic approach. METHODS: This retrospective study examined 15 consecutive operations for lymphangiomas in children, ages 5 months to 14 years, treated during the 5-year period from 1999 to 2004. RESULTS: Six patients were treated using the primary laparotomy approach, and nine patients underwent the laparoscopic procedure, six successfully. Three conversions were necessary (1 case requiring partial colectomy, 1 retroperitoneal case with adherence on the aorta and vena cava, 1 case with partial volvulus). Morbidity included two cases of acute occlusion caused by adhesions after laparotomy. There was no recurrence of lymphangioma during a mean follow-up period of 35 months. CONCLUSION: The laparoscopy procedure could be used successfully for abdominal lymphangioma, even in an emergency. When the laparoscopic resection is impossible, laparotomy or sclerotherapy can be discussed.

Crohn's disease in children. Preliminary experience with a laparoscopic approach.

BACKGROUND: Laparoscopic surgery in patients with Crohn's disease (CD) has been demonstrated to have advantages over a conventional approach in children. The aim of this study was to review the children treated for CD with a laparoscopic approach, to report our indications, the surgical procedure, the complications, and to compare the children with pancolitis or ileocaecal (segmental) Crohn's disease. PATIENTS AND METHOD: We reviewed the files of 11 children treated for CD in a single institution between 1999 and 2004 for a retrospective study of clinical and surgical data. Mann-Whitney U-test was used for statistical analysis of nonparametric data. RESULTS: Eleven children were operated. The average age when initial clinical symptoms became apparent was 12.1 years (range 6.6 - 15), and surgery was performed after an average of 3.4 years of disease (range 1 - 7.6). The surgical indications were stenosis in 6 cases, failure to thrive in 1 case (segmental CD, SCD group) and pancolitis refractory to medical treatment in 4 cases (pancolitis group, PCD group). Mean operative time was 207 minutes (range 140 - 270) for the SCD group and 285 minutes (range 260 - 300) for the PCD group (p < 0.05). Three cases needed a conversion to open surgery (2 in PCD group, one in SCD group), mainly in relation to anastomosis performed with an EEA stapler. The average length of surgical unit stay was 6.5 days (range 4 - 8) for the PCD group and 6.4 days (range 4 - 8) for the SCD group; average follow-up was 16 months (range 3 - 38). Two patients had a relapse of CD (stenosis of the anastomosis in one, skin fistula in the other). CONCLUSION: A laparoscopic approach for ileocolic resection in Crohn's disease is a feasible procedure, even in cases of pancolitis. We recommend an extra-corporeal anastomosis because, in relation to the inflammatory bowel, the mechanical anastomosis is not a safe procedure in cases of pancolitis.

Reimplantation of oesophageal bronchus following a type III oesophageal atresia repair.

Oesophageal atresia can be associated with communicating bronchopulmonary foregut malformations, the most common being the oesophageal bronchus. Lung resection may be mandatory, but conservative treatment correcting the abnormal airway has been proposed, raising the difficult issue of perioperative ventilatory support. The authors report a case of successful reimplantation of oesophageal bronchus revealed after surgical cure of an oesophageal atresia with tracheo-oesophageal fistula.

Open vs thorascopic surgical management of bronchogenic cysts.

BACKGROUND: The aim of this study was to compare the operative outcome in children undergoing open vs thoracoscopic resection of bronchogenic cysts. METHODS: The medical records of children who underwent the resection of bronchogenic cysts from 1990 through 2000 were reviewed. Four cyst resections were performed by the open technique and five using a thoracoscopic procedure. The age of the patients, length of hospital stay, duration of drainage, operating time, and outcome were investigated. RESULTS: The mean age of patients undergoing the open procedure was 3 years and 3 months; the mean age for thoracoscopy patients was 7 years and 10 months (p < 0.05). The operating time for the open procedure was 70 +/- 25 min; for the laparoscopic procedure, it was 78 +/- 6 min (p, NS), except in one case with a main bronchial tail that required conversion (320 min). Duration of surgical drainage was 6.5 +/- 3 days for the open procedure and 2.5 +/- 1 days for the thoracoscopic one (p < 0.05). Hospital stay for open patients was 12 days +/- 0 days; it was 6 +/- 1.6 days for thoracoscopic patients (p < 0.01). There were no deaths. The thoracoscopic procedure failed once due to a main bronchial tail and had to be converted to an open procedure. Other early complications included a bronchopulmonary infection after an open cyst excision and an atelectasis after a thoracoscopic cyst excision. Late complications included one reoperation for incomplete excision in each of the two groups. CONCLUSION: Bronchogenic cyst resection can be performed safely. For complete treatment of these patients, total excision of the wall cyst is needed. In selected patients, the thoracoscopic procedure may decrease the duration of surgical drainage and length of hospital stay without increasing the operating time or MSK for complications.

Laparoscopic approach as primary treatment of common bile duct stones in children.

BACKGROUND: Preoperative endoscopic retrograde cholangiopancreatography and endoscopic sphincterotomy (ES) are an effective strategy for choledocholithiasis, but complications such as pancreatitis and outcome in children are unknown. The laparoscopic cholecystectomy became the new gold standard in children for cholelithiasis. For the choledocholithiasis in children, the attitude is more controversial. We analyzed our series of laparoscopic approach for the management of choledocholithiasis in children to determine if it is an effective procedure. PATIENTS AND METHOD: Between 1996 and 2001, 126 children were treated for cholelithiasis in our institution; 13 children (10.3%) were managed for a choledocholithiasis. We reviewed age at symptom onset results of paraclinical examinations, the type of laparoscopic management, and postoperative outcome. RESULTS: The mean age at clinical signs was 9.9 years (range, 3 months-15.5 years). One child was excluded because he had a preoperative ES. Twelve children had a laparoscopic cholecystectomy and cholangiogram at the same time. A choledocholithiasis was found in 10 cases. A flush of the common bile duct (CBD) was performed in all cases with a 3F or 5F ureteral catheter; the stone was pushed into the duodenum in 3 cases and successfully extracted in 3 with a 4F Dormia or Fogarty catheter. One child needed a conversion to open surgery. Three times, an ES was necessary in postoperative course in each case for clinical and biologic signs of CBD obstruction or pancreatitis (30%). All children are symptom-free with an average follow-up of 28 months. CONCLUSION: Laparoscopic CBD exploration for choledocholithiasis can be performed safely in children at the time of cholecystectomy and can clear all of the stones in the CBD in two thirds of cases. If there is residual obstruction, a postoperative ES can be performed. We suggest primary treatment of choledocholithiasis by laparoscopic approach in children.

Left thoracoscopic thymectomy in children.

BACKGROUND: In the management of autoimmune myasthenia, thymectomy is recognized as effective surgical therapy. The necessity of complete radical thymectomy to achieve maximal improvement has been emphasized. Video-assisted thoracoscopic surgery has been successfully used for thymectomy in adults, and more recently in children, and has been described as achieving the same radicality and functional improvement as median sternotomy or as transcervical thymectomy. The aim of this work is to report our first thoracoscopic experience in this indication. METHODS: Patients with myasthenia gravis on anticholinesterase drugs and/or steroids are discussed for surgery in case of clinical deterioration despite increasing doses of medication or in case of no improvement. We decided to perform thoracoscopic thymectomies by a left-sided approach. Preoperative localization of thymic tissue is done by a thoracic CT exam. Patients are placed on their right side with a thoracic tilt under the thorax. Four thoracoscopic ports are used, a 10-mm for the camera and three 5-mm operating ports. The left lung was collapsed by selective intubation (double-lumen endotrachial intubation). RESULTS: Two boys, 7.5 and 14 years old, were addressed by the department of neurology for radical thymectomy. They presented an ocular myasthenia gravis for 2 years and a mild general myasthenia gravis for 7 years. The operative times were 120 and 240 min. There was no intraoperative or postoperative complication. Duration of thoracic drainage was 2 days. The children were discharged on the third postoperative day. For the second procedure, an ultrasound exam during surgery was necessary to localize the thymus exactly, thus enabling its complete resection without the need for a conversion. The follow-up is 19 and 7 months with a clinical improvement enabling the diminution of medication for both children, the end of ptosis for the first child, and the general improvement of muscle strength for the second. CONCLUSIONS: Thoracoscopic thymectomy in children with juvenile myasthenia gravis seems to offer a complete surgical resection, as do open techniques. In case of difficulties in finding the thymus, an ultrasound exam is feasible to enable complete resection. The left-sided thoracoscopic approach gives a good mediastinal and cervical exposition. Furthermore, being less painful in the postoperative period, it presents a less pronounced impairment of pulmonary function, and it presents good cosmetic effect.

Pediatric laparoscopic splenectomy: benefits of the anterior approach.

INTRODUCTION: Splenectomy is frequently performed in children for various hematologic and autoimmune disorders. We reviewed our indication for splenectomy, our technique of laparoscopic, splenectomy, and our results. The aim of this study was to show if an anterior approach with elective vessel endoligature in a patient in decubitus position was a better and safer approach than the other techniques previously published. PATIENTS AND METHODS: Between January 1996 and December 2002, 54 children underwent laparoscopic splenectomy. We use the anterior pedicle approach and elective vessel endoligature in order to prevent persistence of any exogenous material. Sixteen children also had a concomitant cholecystectomy. Their age ranged between 1 and 18 years (mean 7.5 years). Twenty children had hereditary spherocytosis, 15 were affected by sickle cell disease, six had an idiopathic thrombocytopenia, four had beta-thalassemia, and nine another hemolytic disease. RESULTS: Mean operative time was 150 min (range, 115-230 min). Hospital stays ranged from 3 to 15 days (mean: 5.4). Seven patients had complications (four pneumonia and three deep abscess with successful antibiotic treatment). Median follow-up was 42 months (2 months-6 years) without problems regarding procedure. DISCUSSION: With this technique consisting in first elective arterial and secondary venal ligature, we preserved blood splenic sequestration and pancreatic tail lesion. The procedure is safer. For us, considering the low complication rate for this type of patient, and the advantages of a small abdominal trauma in the postoperative period, laparoscopy with anterior approach for elective splenectomy and eventual cholecystectomy in hematologic disorders is the best technique.

Laparoscopic distal pancreatectomy for Frantz's tumor in a child.

Solid pseudopapillary tumor of the pancreas is a rare pathologic entity. Although the role of laparoscopy in surgery of the pancreas is still controversial, laparoscopic distal pancreatectomy has been reported with good results in adults. We report a laparoscopic spleen-preserving distal pancreatectomy in a 9-year-old boy who presented with a low-grade malignant tumor. Needle biopsy was impossible. A laparoscopic spleen-preserving distal pancreatectomy was performed. We used four trocars, and the operative time was 240 min. Conversion to open surgery was not necessary. The boy's postoperative recovery was uneventful, and he was discharged on the 6th day. CT-scan control at 6 months was normal. This case shows that even in advanced surgical cases, such as spleen-preserving distal pancreatectomy, laparoscopic procedures can be done safely, within a reasonable operative time, in children.

Prenatal management of gastroschisis: the place of the amnioexchange procedure.

Gastroschisis is a malformation of the anterior abdominal wall that consists of a right paraumbilical defect with bowel loops bathed in the amniotic fluid. The survival rate is now greater than 90% and the prognosis relies mainly on morbidity attributable to bowel dysfunction. Recent research has examined gastrointestinal waste present in amniotic fluid that induces bowel toxicity and an inflammatory process. The amnioexchange procedure (changing the amniotic fluid regularly) involves a new therapeutic approach: reducing bowel injuries in the fetuses. This article shows that there is an inflammatory reaction in human gastroschisis and in the authors' model, and that the clinical and biological data plead for the practice of amnioexchange in human beings. A randomized, controlled study is now needed.

Laparoscopic adrenal surgery for neuroblastomas in children.

PURPOSE: The role of laparoscopy in children with neuroblastomas has not been fully defined. The laparoscopic approach to the adrenal gland is already largely used in adults and a few cases have been reported in children. We report the experience of a single surgical team center with laparoscopic adrenal surgery for neuroblastomas in children. MATERIALS AND METHODS: Between September 2000 and October 2002 laparoscopic adrenalectomy for neuroblastoma was performed in 9 patients (6 girls and 3 boys) with a mean age of 38 months (range 2 months to 9 years). Two tumors were detected prenatally and 7 postnatally. Preoperative diagnosis was neuroblastoma stage I in 4 cases and stage IV in 3 cases, and nondetermined suprarenal calcified masses in 2 cases. A 4 or 5-trocar transperitoneal approach was used in all cases. The adrenal tumors were completely excised, placed into a plastic bag and removed through the umbilical trocar site. RESULTS: All of the adrenal tumors were well encapsulated and completely excised. One of the 9 procedures was converted to open surgery because of adhesions to renal vessels. In 1 case a second hepatic localization was removed simultaneously, and in 3 cases 1 or more lymph nodes were resected. Average operative time was 85 minutes (range 45 to 170). There were no deaths. There were no postoperative complications, except 1 port site infection that was treated locally. Blood transfusion was not required. Average hospital stay was 4.5 days (range 2 to 10). Histological analysis of the 9 specimens (maximum length 6 cm) confirmed the diagnosis of neuroblastoma. N-myc status was studied in 8 of the 9 resected neuroblastomas and was amplified in 2 cases (both stage IV with preoperative biopsy). Average postoperative followup was 15 months (range 1 to 25). There was no local recurrence or metastasis, except in the case that required conversion to open surgery (local recurrence 7 months later). CONCLUSIONS: Laparoscopic adrenalectomy for neuroblastoma is safe and feasible in children, with good results. Experience with advanced laparoscopic surgery is required to achieve this result in optimal oncological conditions. Our short-term results must be reevaluated at long term, and further studies are needed to compare laparoscopy to open surgical techniques.

Esophageal ligature in experimental gastroschisis.

BACKGROUND/PURPOSE: Recently, the authors have shown that in human fetuses suffering from gastroschisis, there is an amniotic fluid inflammatory response and that amniotic fluid exchange designed to disrupt the inflammatory loop seems to have a favorable impact on outcome. The authors, therefore, designed in the fetal sheep a model of gastroschisis in which amnioinfusion significantly improved the deleterious process. They hypothesized that regurgitation and presence of digestive enzyme in the amniotic fluid triggers and maintains the process of inflammation. METHODS: To test this hypothesis, the authors used their model of gastroschisis in the fetal lamb combined with esophageal ligation and compared it with gastroschisis with or without amnioinfusion. RESULTS: Of 34 fetuses operated on at midgestation (days 70 through 80), 11 died in utero or were stillborn, 8 had gastroschisis and amnioinfusion, 8 had gastroschisis and no amnioinfusion, and 7 had gastroschisis and esophageal ligation. There were 9 control fetuses. Fetuses were killed at day 145 by cesarean section. Extraabdominal bowels with fibrous peel were processed for histologic examination. Thickness of bowel muscularis (micrometers) was 82.7 +/- 19 for controls, 159 +/- 56 for the nonamnioinfused fetuses, 126 +/- 21 for the amnioinfused fetuses (P =.001), and 240 +/- 225.8 for fetuses with esophageal ligature combined with gastroschisis. The same results were obtained for thickness of serous fibrosis and plasma cell infiltration. Assay of amniotic fluid ferritin, lipase, and protein showed that only amnioinfusion lowered ferritin and protein to levels similar to those of controls, thus, illustrating its preventive effect on inflammation and that esophageal ligature did not prevent digestive enzyme presence in the amniotic fluid. CONCLUSION: In this model of gastroschisis in the fetal sheep, ligature of the esophagus, which was supposed to protect the extruded bowel by preventing oral regurgitation of digestive enzymes and by creating a relative hydramnios, did not improve the inflammatory and deleterious process, which is best prevented by amnioinfusion.

Follow-up of partial splenectomy in children with hereditary spherocytosis.

BACKGROUND/PURPOSE: The aim of this report is to study the short- and long-term consequences of partial splenectomy (PS) in hereditary spherocytosis (HS). METHODS: The authors reviewed the files of 5 children who underwent PS from 1993 to 1998. The data collected included clinical presentation, age, gender, indication for the operation, radiographic examination, need for blood transfusion and hematologic values, description of surgical procedure, and early- and late-occurring complications. RESULTS: From 1993 to 1998, 5 children from one year, 9 months to 7 years of age underwent PS. Indications were hypersplenism and severe anemia. The average age at the time of the operation was 3 years, 5 months. The 2 youngest children (one year, 9 months and 2 years old) needed a second operation because of the recurrence of hypersplenism. CONCLUSIONS: Subtotal splenectomy seems to preserve the immune role of the spleen and can reduce the need for blood transfusion. But PS is associated with a regrowth of the splenic remnant in children suffering from chronic hemolysis with hypersplenism and seems to be effective for a relatively short period only, especially in young children. Thus, a second operation to perform a total splenectomy can be necessary. The decision to perform a PS on young children with HS as an alternative to total splenectomy with appropriate preoperative vaccination and postoperative prophylactic antibiotics therefore should be weighed carefully, keeping in mind, however, the benefit of postponing total splenectomy in these patients.

Definitive treatment of extended Hirschsprung's disease or total colonic form.

BACKGROUND: Between December 1990 and March 1999, five laparoscopic Duhamel pull-through procedures for extended or total aganglionosis were performed in our department, one of which had a rectosigmoid form with a short bowel and a colonic resection due to a volvulus. METHODS: The aim of this study was to show that even when the extended form of Hirschprung's disease or anatomic difficulties such as a short bowel and anterior colonic resection are encountered, the laparoscopic approach is possible and total colectomy is feasible. The procedure has been described previously. We used one camera port and three working ports. The sigmoid, transverse, and right colon up to the last ileal cove were mobilized laparoscopically. A standard posterior ileo-anal anastomosis was performed, and an endo-GIA stapler was used for the anterior anastomosis. RESULTS: A total of five patients underwent laparoscopic surgery for Hirschprung's disease. There were three total colonic forms, one rectosigmoid form with a short bowel and colon resection attributed to a volvulus, and one transverse variant that required a Deloyers' maneuver for the pull-through. Three of the infants required total parenteral nutrition (TPN) for an average of 49 days (range, 28-60) from diversion until the time of the definitive procedure. Only one patient did not receive TPN. Postoperatively, there were two complications-one wound infection and one hectic fever. The clinical results were good, with no soiling or stool incontinence and no constipation. CONCLUSION: The laparoscopic procedure for total aganglionosis or the extended form of Hirschprung's disease is safe, feasible, and reproducible.

Improvement of mesenteric superior artery Doppler velocimetry by amnio-infusion in fetal gastroschisis.

This study aimed to analyse the influence of amnio-infusion on superior mesenteric Doppler velocimetry and to correlate Doppler data with outcome in fetuses presenting with gastroschisis. Umbilical and intra- and extra-abdominal superior mesenteric artery Doppler velocimetry was measured prospectively before and after amnio-infusion in fetuses with gastroschisis. Doppler index values and changes were correlated with the following outcome parameters: importance of fibrous coating, duration of hospitalization in the neonatal intensive care unit, total duration of hospitalization, duration of parenteral feeding, duration of ventilatory assistance, and the interval to initiation of oral feeding. A significant improvement of diastolic flow was observed in the extra-abdominal superior mesenteric artery with amnio-infusion. No similar change was seen in the intra-abdominal superior mesenteric or in the umbilical artery. Pre-amnioinfusion extra-abdominal mesenteric Doppler index was correlated with maximal diameter of exteriorized bowel and slightly with duration of hospitalization in the neonatal intensive care unit, but no other relation between Doppler index and outcome parameter could be ascertained. Amnio-infusion induces modifications in the vascularization of exteriorized bowel in gastroschisis. This could partly explain the beneficial effect of this procedure on fetal gut.

Bronchial trifurcation in a congenital pulmonary venolobar syndrome.

Congenital malformations of the tracheobronchal tree and the related arterial blood supply are a complex group of lesions in which there are abnormalities of the venous drainage and lung parenchyma. These malformations are examples of congenital pulmonary venolobar syndrome (CPVS). Tracheal trifurcation is an extremely rare anomaly associated with CPVS. We report on an unusual case of lower right extralobar sequestration connected to the trachea, plus a type I posterior laryngeal cleft, an aberrant systemic artery, and an anomalous route of the phrenic nerve. This paper discusses the place of this unusual abnormality in the spectrum of congenital bronchopulmonary vascular malformations.

Laparoscopic adrenalectomy in children.

BACKGROUND: The aim of this study was to describe the indications and results of laparoscopic adrenalectomy in children. METHODS: This retrospective multicenter study included six children (four boys, two girls) aged 2-16 years (mean, 9.5). Three children had hypertension. In three cases, the adrenal mass was discovered incidentally. The tumors were bilateral in two children, right-sided in two cases, and left-sided in two cases. The mean tumor size was 4 cm (range, 1-7). Each child underwent MIBG scintigraphy and MRI before the operation. RESULTS: Four right and two left adrenal glands were resected by laparoscopy (transperitoneal), and two left glands were resected by retroperitoneoscopy. Two conversions were necessary for two left adrenal glands (one retroperitoneoscopy, one laparoscopy). Two partial resections and six adrenalectomies were performed. Histological examination of the tumors revealed two ganglioneuromas, one neuroblastoma, and five pheochromocytomas (two bilateral). One child had an involved node (pheochromocytoma). Both bilateral pheochromocytomas had von Hippel-Lindau disease. There was no morbidity. Mean hospitalstay was 6 days. Postoperative evaluation at 1 month was normal in all children. CONCLUSION: The indications for laparoscopic adrenalectomy in children are benign tumors and pheochromocytomas. In these cases, laparoscopic adrenalectomy is feasible and safe, even in cases of pheochromocytoma.

[Laparoscopic splenectomy in children: experience and results].

UNLABELLED: Pediatric laparoscopic splenectomy is a relatively new surgical procedure. Advances in instrumentation and technique now make this procedure possible. Splenectomy is frequently performed in children for various hematologic and autoimmune diseases. PATIENTS AND METHODS: This article reviews the indication for splenectomy, the technique of laparoscopic splenectomy and our results. Between January 1996 and January 2000, 23 children underwent laparoscopic splenectomy. Three of them also had a concomitant cholecystectomy. Their ages ranged from three to 14 years. Nine children had hereditary spherocytosis, four were affected by sickle cell disease, three had an idiopathic thrombocytopenia and three a hemolytic disease. One patient was converted. RESULTS: Mean operative time was 170 min (range, 115-230 min). Hospital stay ranged from three to 15 days (median, 6). Five patients had complications (three pneumonia and two deep abscesses). Median follow-up was 20 months (two months to four years) without problems regarding procedure. CONCLUSION: Regarding the low complication rate for this type of patient and the advantages of a small abdominal trauma in the postoperative period, the laparoscopic approach for elective splenectomy in hematological disorders is the technique of choice.
