Skipped Aganglionic Lengthening Transposition (SALT) is highly effective to achieve enteral autonomy in selected patients with intestinal failure secondary to total intestinal aganglionosis.

BACKGROUND: Intestinal Failure, parenteral nutrition (PN) dependence, and subsequent liver disease are the most challenging and life-threatening complications of short bowel syndrome experienced by patients with total intestinal aganglionosis. Skipped Aganglionic Lengthening Transposition (SALT) showed to be a promising procedure to overcome such problems. We herein report the results of two patients who underwent SALT at the Umberto Bosio Center for Digestive Diseases. PATIENTS AND METHODS: Between November 2019 and July 2022, 2 patients with total intestinal aganglionosis underwent SALT as autologous intestinal lengthening procedure. Perioperative data and long-term outcomes are reported. Patient #1-A 18 month-old male (PN dependant) with 30 cm of ganglionated bowel at birth experienced a 35% increase of intestinal length after SALT (from 43 to 58 cm) thanks to three 5 cm interposed aganglionic loops. Postoperative course was uneventful and he was totally weaned by PN after 28 months postoperatively. He is without PN only receiving enteric feeding 53 months after the procedure. Patient #2-A 11 year-old female (PN dependant) with 100 cm of ganglionated jejunum underwent SALT at 11 years and experienced a 19% increase of bowel length thanks to four 5 to 7 cm interposed aganglionic loops. Postoperatively she required excision of two out of the four loops due to severe strictures and inadequate perfusion with a subsequent overall 10% increase of length after SALT. Of note, she improved significantly with a progressive reduction of PN that has been stopped after 18 months. CONCLUSION: Skipped aganglionic lengthening transposition (SALT) seems to be very effective in improving nutrients absorption in patients with total intestinal aganglionosis by increasing absorptive bowel surface and decelerating intestinal flow for a longer and more effective contact of enteric material with ileal mucosa. Provided these impressive results are confirmed in the very long-term, SALT could become a valid alternative for the treatment of patients with total intestinal aganglionosis carrying at birth at least 20 to 30 cm of ganglionated jejunum.

Long-term results of EPSiT in children and adolescents: still the right way to go.

INTRODUCTION: Endoscopic pilonidal sinus treatment (EPSiT) has been advocated promising excellent outcomes with low rates of complications and recurrences. In this study, we aimed at reporting long-term results of a unicentric series of pediatric patients who underwent EPSiT during a 5-year period. MATERIALS AND METHODS: We retrospectively reviewed patients who underwent EPSiT between January 2017 and December 2021. Patients under 18 years of age at first surgery were included. Details regarding demographic data, surgical procedure, and recurrences were recorded. Patients were also divided into short-term (follow-up of 12 months) and long-term (follow-up longer than 36 months) to compare results and detect all possible delayed recurrences. RESULTS: A total of 99 patients underwent 115 EPSiT procedures in a 5-year period. Median age was 16 years (8-19 years). Median length of surgery was 32 min (25 to 50 min). Eighty-three of these patients were assessed for short-term results and reported an 8% incidence of recurrences occurring after a mean of 6 months. Fifty-nine patients have been followed up for at least 36 months (long-term results) with a median follow-up of 49 months (36-61 months) and reported a 15% incidence of recurrences occurring after a mean of 19 months postoperatively. All patients who recurred required a redo EPSiT. Infections occurred in 5 (2 recurred) and bleeding in 1 (no recurrence). CONCLUSIONS: Recent reports underlined impressive results and an extremely low recurrence rate of EPSiT. Our retrospective study addressed the long-term results and seems not to support these expectations. Even so, EPSiT remains easy, straightforward, allows rapid recovery and is, therefore, to be considered as one of the most promising surgical techniques available for pilonidal disease. EPSiT is here to stay and to remain.

Skipped aganglionic lengthening transposition (SALT) for short bowel syndrome in patients with total intestinal aganglionosis: technical report and feasibility.

Extended aganglionosis (TIA) is the presence of some viable aganglionic gut distal to the levelling jejunostomy. Different surgical procedures (including transplantation) have been proposed with inconclusive results. We conceived a new procedure named skipped aganglionic lengthening transposition (SALT) consisting of multiple pedicled isoperistaltic transpositions of aganglionic ileal loops interposed to normoganglionic jejunum. The innovative aspect consists of taking advantage of the propulsive effect of normoganglionated bowel to progress enteric content throughout interposed aganglionic loops down to the stoma. The procedure was adopted in a male patient who was born with 30 cm of normoganglionated jejunum. SALT was performed when the baby was 18 months. Three 5-cm pedicled isoperistaltic aganglionic loops of small bowel were interposed each 10 cm of normoganglionic jejunum with an overall 36% length gain (from 42 to 57 cm). Postoperative course was uneventful. 6 months postoperatively, an upper gastrointestinal series showed normal progression without dilatations. A laparoscopic gastrostomy was performed due to food aversion 6 months postoperatively, demonstrating impressive anatomic and functional postoperative results. The procedure provides promising and unique opportunity for patients with TIA with encouraging outlook for the near future.

Brachiocephalic vein for percutaneous ultrasound-guided central line positioning in children: A 20-month preliminary experience with 109 procedures.

BACKGROUND: Ultrasound-guided (USG) cannulation of the brachiocephalic vein (BCV) is gaining worldwide consensus for central venous access in children. This study reports a 20-month experience with this approach in children. METHODS: All patients who underwent percutaneous USG central venous catheter (CVC) positioning in the BCV between August 2013 and March 2015 have been included. Devices inserted during this period were open-ended, either single or double-lumen tunneled CVC. Our series was divided into three consecutive study periods in order to determine the relative incidence of repositioning and complications. RESULTS: During the study period, a total of 95 patients underwent 109 CVC insertions in the BCV. The median length of CVC duration was 230 days for a total of 23,212 catheter days. No major intraoperative complications occurred. Overall rate of CVC-related postoperative complications requiring repositioning or precocious removal was 0.90 per 1,000 catheter days and involved 21 CVC (19%, 95% confidence interval 13-28). These included 18 dislodgments, two infections, and one malfunction. Double-lumen CVCs represented the only significant risk factor for complications (52% complications-three per 1,000 catheter days). CONCLUSION: USG supraclavicular cannulation of the BCV represents a safe approach for central line placement in children. It proved to be versatile, as it can be used in premature infants as well as in adolescents. Provided it is adopted by operators experienced in USG cannulation, we strongly suggest to resort to this approach as a first-line choice in children undergoing tunnelled central line placement for long-lasting therapy.

Preliminary results of video-assisted anal fistula treatment (VAAFT) in children.

BACKGROUND: Anal fistula is a common acquired anorectal disorder in children. Treatment methods that have been used are associated with inconsistent results and possible serious complications. In 2011 a minimally invasive approach, video-assisted anal fistula treatment (VAAFT) was described for adult patients. The aim of the present study was to assess the first series of pediatric patients treated with VAAFT. METHODS: All patients who underwent VAAFT between August 2013 and May 2015 were included. Demographics, clinical features, preoperative imaging, surgical details, outcome, and medium-term data were prospectively collected for each patient. RESULTS: Thirteen procedures were performed in nine patients. The male to female ratio was 8:1, and the median age was 9.6 years. Five fistulas were idiopathic, three iatrogenic, and one associated with Crohn's disease. Eight complete VAAFT procedures were performed. The remaining five procedures were either fistuloscopy and cutting seton placement or fistuloscopy and electrocoagulation, both without mucosal sleeve. The median length of surgery was 41 min. The median hospital stay was 24 h, and the median length of follow-up was 10 months. Resolution of the fistula was observed in all patients who underwent a complete VAAFT. In four out of five patients who underwent an incomplete procedure (without mucosal sleeve), the fistula recurred. No incontinence or soiling was reported in the medium term. CONCLUSIONS: VAAFT proved to be feasible and safe in children. It also proved to be versatile as it could be applied to fistulas of different etiologies. The key to success seems to be an adequate mucosal sleeve. Older children and adolescents benefit most from VAAFT which is a valid alternative to available surgical procedures.

Inguinal hernia in neonates and ex-preterm: complications, timing and need for routine contralateral exploration.

BACKGROUND/PURPOSE: Aim of this study was to present a series of neonates and ex-preterm babies who underwent inguinal hernia repair focusing on complications and possible indication to perform routine contralateral groin exploration. METHODS: This is a retrospective study of a series of consecutive patients weighing less than 5 kg who underwent inguinal hernia repair between January 2007 and December 2012. Only the affected side was treated. Patients have been routinely followed up postoperatively. We resorted to available outpatients' charts and admission notes to record demographic data, surgical details, complications and the occurrence of metachronous hernias. A questionnaire was administered to all patients' relatives to confirm the long-term outcome. RESULTS: One hundred fifty-four patients were operated for a total of 184 herniotomies (88 right sided, 36 left sided and 30 bilateral). Median length of follow-up was 42 months (range 6 months-7.5 years). Thirteen patients (13/124 = 10.5 %) developed metachronous hernia that proved to be significantly more frequent in patients weighing less than 1,500 g at birth (p < 0.05). We observed 10 % of complications, including 2.7 % testicular atrophy and 4.5 % recurrence. Atrophy proved to occur more frequently in patients who experienced preoperative incarceration (p < 0.05). No other risk factors were identified. CONCLUSIONS: The results of our series demonstrated that, though technically demanding, herniotomy in the neonate and ex-preterm is associated with a relatively low incidence of complications. Based on our results and in accordance with literature data, we do not advocate routine contralateral exploration in case of unilateral hernia but surgery to be performed only on the symptomatic side, as soon as possible after initial diagnosis. Very low birth weight patients should be followed with care in the early postoperative period due to the higher likelihood of developing a metachronous hernia.

A Structured Training for Trans Anal Irrigation in Pediatric Patients Improves Outcomes and Reduce Failures: Results of an Interventional Multicenter Prospective Study.

BACKGROUND: Continence issues due to organic causes including previous colorectal surgery or neurological issues might benefit from Transanal irrigation (TAI) that proved to be highly effective but with a number of limitations including a relatively high discontinuation rates. Our study was aimed at evaluating the efficacy of an advanced protocol tailored to each patient to prevent dropout and increase satisfaction, independence, and quality of life. MATERIALS AND METHODS: This was a prospective, interventional, multicenter, nonrandomized study involving children aged 4-18 years with bowel dysfunction unresponsive to conventional treatments who required TAI. TAI was performed in accordance to the best standards of care with a total irrigation volume that was determined based on low emission X-Ray barium enemas performed at the very beginning of the study. All patients underwent training and assessments of continence, patients' perspectives and quality of life were performed at different timepoints from enrollment (T0) up to 6 months since TAI was introduced (T3). RESULTS: A total of 78 patients were enrolled. Male to female ratio was 1.4:1. Mean age at enrollment was 106.1 ± 42.8 months. Discontinuation was reported by 3 patients (3.8 %). Continence, satisfaction and a number of other outcome measures increased from baseline (T0) to the last visit (T3). In particular, mean Rintala total score increased linearly from 7.8 to 14.8 during the study period (T0 to T3 timepoints). On a multivariate analysis, the only parameter that proved to be inversely associated with continence as well as with other outcome measures was the use of laxatives at enrollment and during the study. CONCLUSIONS: This study has demonstrated the high efficacy of this innovative patient-tailored TAI protocol across all assessed scores. Of note, given the negative impact of laxatives, our findings suggest limiting their use in this patient population to further increase the efficacy of the procedure.

Case report: Gastroenterological management in a case of cardio-facio-cutaneous syndrome.

Background: cardio-facio-cutaneous syndrome is a rare genetic disorder affecting less than 900 people in the world. It is mainly characterized by craniofacial, dermatologic and cardiac defects, but also gastroenterological symptoms may be present, ranging from feeding difficulties to gastroesophageal reflux and constipation.In this report we describe a case of this syndrome characterized by severe feeding and growth difficulties, with a particular focus on the management of gastroenterological complications. Case presentation: the patient was a caucasian male affected by Cardio-Facio-Cutaneous syndrome who presented feeding difficulties already a few hours after birth. These symptoms worsened in the following months and lead to a complete growth arrest and malnutrition. He was first treated with a nasogastric tube placement. Subsequently, a laparoscopic Nissen fundoplication and a laparoscopic Stamm gastrostomy were performed. The child was fed with nocturnal enteral nutrition and diurnal oral and enteral nutrition. Eventually the patient resumed feeding validly and regained adequate growth. Conclusion: this paper aims to bring to light a complex rare syndrome that infrequently comes to the attention of the pediatricians and whose diagnosis is not always straightforward. We also highlight the possible complications under a gastroenterologic point of view. Our contribution can be helpful to the pediatrician in the first diagnostic suspect of this syndrome. In particular, it is worth highlighting that -in an infant with Noonan-like features- symptoms like suction or swallowing problems, vomiting and feeding difficulties should orient towards the diagnosis of a Cardio-facio-cutaneous syndrome. It is also important to stress that its related gastroenterological issues may lead to severe growth failure and therefore the role of the gastroenterologist is key to manage supplemental feeding and to establish whether a nasogastric or gastrostomic tube placement is necessary.

A unicentric cross-sectional observational study on chronic intestinal inflammation in total colonic aganglionosis: beware of an underestimated condition.

BACKGROUND: Inflammatory Bowel Diseases (IBD) are known to occur in association with Hirschsprung disease (HSCR). Most of cases are represented by Crohn Disease (CD) occurring in patients with Total Colonic Aganglionosis (TCSA) with an estimated prevalence of around 2%. Based on these considerations and on a number of provisional data belonging to our Center for Digestive Diseases, we developed a unicentric cross-sectional observational study aimed at describing phenotype, genotype, pathology and metagenomics of all patients with TCSA and Crohn-like lesions. RESULTS: Out of a series of 62 eligible TCSA patients, 48 fulfilled inclusion criteria and were enrolled in the study. Ten patients did not complete the study due to non-compliance or withdrawal of consent and were subsequently dropped out. A total of 38 patients completed the study. All patients were tested for chronic intestinal inflammation by a combination of fecal calprotectine (FC) or occult fecal blood (OFB) and underwent fecal metagenomics. Nineteen (50%) tested positive for FC, OFB, or both and subsequently underwent retrograde ileoscopy. Fourteen patients (36.8%) presented Crohn-like lesions, occurring after a median of 11.5 years after surgery (range 8 months - 21.5 years). No statistically significant differences regarding demographic, phenotype and genotype were observed comparing patients with and without lesions, except for need for blood transfusion that was more frequent in those with lesions. Faecal microbiome of patients with lesions (not that of caregivers) was less biodiverse and characterized by a reduction of Bacteroidetes, and an overabundance of Proteobacteria. FC tested negative in 3/14 patients with lesions (21%). CONCLUSIONS: Our study demonstrated an impressive 10-folds higher incidence of chronic inflammation in TCSA. Up to 50% of patients may develop IBD-like lesions postoperatively. Nonetheless, we failed in identifying specific risk factors to be used to implement prevention strategies. Based on the results of our study, we suggest screening all TCSA patients with retrograde ileoscopy regardless of FC/OFB values. The frequency of endoscopic assessments and the role of FC/OFB screening in prompting endoscopy is yet to be determined.

Intraoperative bronchoscopy for bronchial carcinoid parenchymal-sparing resection: a pediatric case report.

Bronchial carcinoid tumors are the most common primary pulmonary neoplasm in the pediatric population. The widely accepted treatment for carcinoid tumors is surgical, specifically aiming at being as much as conservative on lung parenchyma, while the entire tumor is resected. A brief case is described, highlighting the importance and advantages of a surgical and endoscopic combined approach.

Megacystis, megacolon, and malrotation: a new syndromic association?

Chronic intestinal pseudo-obstruction (CIPO) can occur as a consequence of neuropathies including diffuse Intestinal Neuronal Dysplasia (IND), a relatively rare enteric nervous system (ENS) abnormality. Although various authors reported of diffuse IND associated either with intestinal malrotation or megacystis, the co-existence of these three entities in the same patient has never been described before. The aim of this paper is to report for the first time in literature a series of patient with such association, focusing on one who carries a de novo duplication of chromosome 12, suggesting a new syndromic association (megacolon, megacystis, malrotation).

Shifting from open surgical cut down to ultrasound-guided percutaneous central venous catheterization in children: learning curve and related complications.

PURPOSE: Tunneled indwelling central venous catheters (CVC) are essential in the management of children with cancer, hematological, nephrological disorders and for parenteral nutrition. The aim of this study is to present the experience of a single center of the transition from traditional open surgical cut down procedure (OSC) to ultrasound (US)-guided percutaneous CVC insertion, focusing on learning curve and related complications. METHODS: All CVCs inserted between April 2008 and November 2009 in children at the Gaslini Children Hospital were revised, and data on methods of cannulation, intraoperative and device-related complications and re-intervention were recorded. RESULTS: 194 CVCs were positioned in 188 patients. 128 out of 194 CVCs were positioned through an OSC technique, whereas the remaining 66 CVCs were inserted percutaneously with US guidance. Of the 27 recorded complications, 15 were mechanical events, 7 cases developed infection, whereas the remaining 5 (2.6%) were classified as intraoperative complications. A second surgical procedure was described in 23 (11.8%) cases. CONCLUSION: Shifting from OSC to US-guided percutaneous CVC insertion inevitably involves a challenging learning curve which is generally associated with high complication rates. Complications progressively decrease once a good experience in US guidance and percutaneous technique has been obtained.

Genomics approach to the analysis of bacterial communities dynamics in Hirschsprung's disease-associated enterocolitis: a pilot study.

INTRODUCTION: The most invalidating and life-threatening complication in Hirschsprung's disease patients (HSCR) is Hirschsprung's disease-associated enterocolitis (HAEC). The mechanisms underlying enterocolitis have not been identified. The limited knowledge of the role of intestinal microflora is in part due to the complexity of the intestinal microbiome and to the limitation of cultivation-based technologies, given that less than 25% of the intestinal bacterial species can be cultured. MATERIALS AND METHODS: We used amplified ribosomal DNA restriction analysis (ARDRA) with four different restriction enzymes to study variations of microflora composition of the stools of a selected HSCR patient in different clinical conditions (acute phase vs. remission). RESULTS: We assessed a total of 15 stool specimens belonging to the same 3-year-old male patient suffering from HSCR, which were harvested during 4 HAEC episodes and remission phases. Restriction analysis showed that HAEC episodes seem to cluster together at ARDRA analysis, thus suggesting a sort of predisposing bacterial community for HAEC development and the need for a microflora equilibrium to maintain wellness. CONCLUSIONS: This approach proved to be effective, useful and powerful in assessing microflora dynamics and indicated that the differences in microflora associated with acute HAEC or remission are likely to result from a combination of disease activity and different antibiotic therapies. ARDRA proved to be useful in discriminating disease versus remission. Our findings indicated that HAEC results from a change in the equilibrium between bacterial species or from altered discrimination of harmless from harmful microorganisms, challenging the definition of pathogenic and non-pathogenic species. Based on these results, we propose ARDRA as a rapid inexpensive tool to assess microflora dynamics during HAEC episodes.

Search for pathogenetic variants of the SPRY2 gene in intestinal innervation defects.

SPRY2 is an inducible inhibitor of signalling mediated by tyrosine kinases receptors, whose targeting causes intestinal hyperganglionosis in mice. In this light, we have undertaken a mutational analysis of the SPRY2 gene in patients affected with intestinal neuronal dysplasia (IND), without detecting nucleotide changes in any of the 26 DNA samples analysed, with the exception of two already known polymorphic variants. A role of the SPRY2 gene in IND pathogenesis can be thus excluded.

Phenotypic variability of Pai syndrome: report of two patients and review of the literature.

Pai syndrome is a rare form of frontonasal dysplasia, first described in 1987. It is a triad consisting of midline cleft of the upper lip, facial skin polyps and central nervous system lipomas. Only 14 cases have been reported in the literature. The authors describe the clinical features, diagnostic workup and treatment of two patients. A review of all cases reported in literature is presented to show the phenotypic variability of this rare syndrome.

Italian multicentric survey on laparoscopic spleen surgery in the pediatric population.

BACKGROUND: Some technical aspects of laparoscopic spleen surgery still are debated, although efforts have been made to standardize them. The position of the patient, the approach to the spleen, vessel identification and division, and spleen extraction can vary from center to center. METHODS: This retrospective muticentric study led by the Società Italiana di Videochirurgia Infantile (SIVI) examined indications, surgical details, and complications of laparoscopic spleen surgery in the pediatric population during a 5-year period. RESULTS: The study period from January 1999 to December 2003 (5 years) involved nine centers and included 85 patients with a mean age of 10 years (range, 2-17 years). Hypersplenism or severe hemolysis in cases of hematologic disorders represented the most important indications. More than 90% of the patients underwent total laparoscopic splenectomy. Specific technical details from each center were collected. Intraoperative complications occurred in 19% of the patients (hemorrhage in 8% and technical problems in 14%), and 6% of the patients required conversion to the open approach. No deaths occurred, and no reoperations were required. Postoperative complications were experienced by 2% of the patients. CONCLUSION: Laparoscopic spleen surgery is safe, reliable, and effective in the pediatric population. On the basis of the results, some technical details for laparoscopic spleen surgery can be suggested. The patient is preferably kept supine or lateral, approaching the spleen anteriorly. Moreover, the ilar vessels should be identified selectively and individually, with initial artery division performed to achieve spleen shrinking. Any hemostatic device proved to be effective in experienced hands. Once freed, the spleen is preferably extracted via a suprapubic cosmetic transverse incision (faster, easier, and safer), although a bag can be used. Finally, the size of the spleen does not represent a contraindication for a trained and experienced surgeon. Nevertheless, this parameter must be considered when laparoscopic spleen surgery is planned.

Neural crest neuroblasts can colonise aganglionic and ganglionic gut in vivo.

INTRODUCTION: Neural crest (NC) cells differentiate IN VITRO into neuroblasts, precursors of the enteric nervous system (ENS), when stimulated by specific agents. We developed a study aimed at establishing whether NC-derived neuroblasts can survive and colonise IN VIVO when injected into a recipient mouse gut. MATERIALS AND METHODS: The neuroblast precursors of the ENS were obtained from the vagal portion of the neural tubes of 296 CD-1 and GTROSA26 mouse embryos. The embryonic cells of GTROSA26 mice are identifiable through beta-galactosidase activity which allows recognition by blue staining. The host used in this study was the DOM/+ mouse, an animal model for Hirschsprung's disease (aganglionic megacolon). DOM/+ mouse pups (n = 43) received NC-derived cells inoculated into the seromuscular layer of the gut (33/43) or directly into the peritoneal abdominal cavity (10/43). RESULTS: All DOM/+ mice survived the procedure and were sacrificed after 7 or 14 days. Histochemical staining detected implanted cells in all mice. These showed specific myenteric colonisation into the aganglionic and ganglionic gut. CONCLUSION: The striking result of this study was the specific tropism of the injected NC-derived cells to target sites under the action of unknown chemotactic agents. This experimental procedure might represent a possible treatment option for specific forms of human ENS anomaly such as total intestinal aganglionosis.

Is perioperative cholangiography necessary in children undergoing elective laparoscopic cholecystectomy?

BACKGROUND: The necessity of carrying out pre- or intra-operative imaging of the biliary tree to rule out a possible anatomical abnormality or the presence of common bile duct (CBD) stones in patients undergoing laparoscopic cholecystectomy (LC) is debated. We prospectively assessed the risk of developing symptoms related to bile duct injury or CBD stones after LC in children not receiving peri-operative cholangiography. MATERIALS AND METHODS: All patients

Is the laparoscopic Palomo procedure for pediatric varicocele safe and effective? Nine years of unicentric experience.

BACKGROUND: Varicocele is a rare disorder in children that can lead to testicular atrophy and infertility; therefore, radical treatment is frequently required. Whatever treatment is chosen, postoperative complications are fairly common (hydrocele, recurrence, persistence, and testicular atrophy). Laparoscopic varicocelectomy (the laparoscopic Palomo procedure) is one of the surgical options that has recently gained popularity. The aim of this study is to assess the safety and effectiveness of laparoscopic Palomo varicocelectomy by describing a series of patients operated on during a 9 year period at the Royal Hospital for Sick Children in Edinburgh. METHODS: This is a retrospective unicentric study including patients operated on between June 1995 and June 2004. All patients preoperatively underwent ultrasound scan of the testicles (color Doppler) and the abdomen. Indications for surgery included symptoms, high-grade varicocele (grade II and III), and testicular atrophy. Pneumoperitoneum was created using carbon dioxide insufflation with intraabdominal pressure up to 12 mmHg. Three 5 mm ports were inserted. The first port was inserted just below the umbilicus (telescope) under direct vision, and the others were inserted at the left flank and in the suprapubic region. All the enlarged spermatic and vas vessels were ligated or clipped. Outcomes and possible intraoperative, postoperative, or long-term complications are described. RESULTS: Forty-one patients were included in the study. Ninety percent of symptomatic patients improved significantly postoperatively, and 62% of patients with preoperative testicular atrophy showed postoperative catch-up growth of the involved testis. Nevertheless, hydrocele represents the most frequent postoperative complication in this series of patients. Approximately 15% of the patients required some sort of further surgical intervention (12% because of postoperative hydrocele occurrence). CONCLUSIONS: The laparoscopic Palomo procedure is a safe and effective surgical option for the treatment of pediatric varicocele, although it carries a fairly high risk of postoperative hydrocele. Postoperative hydrocele seems to be related to some sort of lymphatic obstruction, therefore lymphatic sparing procedures that can be accomplished laparoscopically should be reconsidered. Nevertheless, their feasibility and effectiveness need to be more carefully assessed.

European multicenter survey on the laparoscopic treatment of gastroesophageal reflux in patients aged less than 12 months with supraesophageal symptoms.

BACKGROUND: This multicenter survey includes neonates and infants who underwent surgery for primary gastroesophageal reflux (GER) who presented with supraesophageal symptoms of unknown origin with a minimum of 12 months postoperative follow-up. METHODS: A total of 726 patients underwent GER surgery in 10 European Centers in the period 1998-2002. Respiratory symptoms were present in 204 patients (28%); 135 patients (17%) had surgery under 1 year of age, and 46 of them (6.3%) because of respiratory symptoms. Surgery was performed without any previous medical treatment in 10 cases (21%). The type of procedure included 37 complete 360 degrees wraps (80%) (Nissen, 12, and Rossetti, 25) and nine partial wraps (20%) (Thal five, Lortat Jacob one, Toupet one, others two). Gastrostomy was associated in 17 cases (37%) (6 PEG and 11 modified Stamm). No gastric emptying procedures were recorded. RESULTS: No major intraoperative complications were reported. Six patients developed complications (13%) and a redo operation was performed in three (6.5%). Respiratory outcome after antireflux surgery was good in 35 patients (76%) and fair with significantly improved respiratory symptoms in 11 (24%). CONCLUSIONS: This multicenter survey underlines that GER has to be suspected and aggressively treated in infants with difficult-to-treat supraesophageal symptoms, and also in high-risk cases, in order to prevent major complications.
