Long-term outcome for children undergoing open hepatico-jejunostomy for choledochal malformations: a 43-year single-center experience

PURPOSE

To report on our 43-year single-center experience with children operated on for Choledochal Malformations (CMs), focusing on long-term results and Quality of life (QoL).

MATERIALS AND METHODS

All consecutive pediatric patients with CMs who underwent surgical treatment at our center between October 1980 and December 2022 were enrolled in this retrospective study. We focused on long-term postoperative complications (POCs), considered to be complications arising at least 5 years after surgery. We analyzed QoL status once patients reached adulthood, comparing the results with a control group of the same age and sex.

RESULTS

One hundred and thirteen patients underwent open excision of CMs with a Roux-en-Y hepaticojejunostomy (HJ). The median follow-up was 8.95 years (IQR: 3.74-24.41). Major long-term POCs occurred in six patients (8.9%), with a median presentation of 11 years after surgery. The oldest patient is currently 51. No cases of biliary malignancy were detected. The QoL of our patients was comparable with the control group.

CONCLUSION

Our experience suggests that open complete excision of CMs with HJ achieves excellent results in terms of long-term postoperative outcomes. However, since the most severe complications can occur many years after surgery, international cooperation is advisable to define a precise transitional care follow-up protocol.

Characterization of Phenotypic Variability in Becker Muscular Dystrophy for Clinical Practice and Towards Trial Readiness: A Two-Years Follow up Study

Background

Becker muscular dystrophy (BMD) is a dystrophinopathy due to in-frame mutations in the dystrophin gene (DMD) which determines a reduction of dystrophin at muscle level. BMD has a wide spectrum of clinical variability with different degrees of disability. Studies of natural history are needed also in view of up-coming clinical trials.

Objectives

From an initial cohort of 32 BMD adult subjects, we present a detailed phenotypic characterization of 28 patients, then providing a description of their clinical natural history over the course of 12 months for 18 and 24 months for 13 of them.

Methods

Each patient has been genetically characterized. Baseline, and 1-year and 2 years assessments included North Star Ambulatory Assessment (NSAA), timed function tests (time to climb and descend four stairs), 6-minute walk test (6MWT), Walton and Gardner-Medwin Scale and Medical Research Council (MRC) scale. Muscle magnetic resonance imaging (MRI) was acquired at baseline and in a subgroup of 9 patients after 24 months. Data on cardiac function (electrocardiogram, echocardiogram, and cardiac MRI) were also collected.

Results and conclusions

Among the clinical heterogeneity, a more severe involvement is often observed in patients with 45-X del, with a disease progression over two years. The 6MWT appears sensitive to detect modification from baseline during follow up while no variation was observed by MRC testing. Muscle MRI of the lower limbs correlates with clinical parameters.Our study further highlights how the phenotypic variability of BMD adult patients makes it difficult to describe an uniform course and substantiates the need to identify predictive parameters and biomarkers to stratify patients.

Biomolecules of Muscle Fatigue in Metabolic Myopathies

Metabolic myopathies are a group of genetic disorders that affect the normal functioning of muscles due to abnormalities in metabolic pathways. These conditions result in impaired energy production and utilization within muscle cells, leading to limitations in muscle function with concomitant occurrence of related signs and symptoms, among which fatigue is one of the most frequently reported. Understanding the underlying molecular mechanisms of muscle fatigue in these conditions is challenging for the development of an effective diagnostic and prognostic approach to test targeted therapeutic interventions. This paper outlines the key biomolecules involved in muscle fatigue in metabolic myopathies, including energy substrates, enzymes, ion channels, and signaling molecules. Potential future research directions in this field are also discussed.

Proposal of a new clinical protocol for evaluating fatigability in adult SMA patients

Objective

Spinal Muscular Atrophy (SMA) is a genetic neuromuscular disease affecting the lower motor neuron, carrying a significant burden on patients' general motor skills and quality of life, characterized by a great variability in phenotypic expression. As new therapeutic options make their appearance on the scene, sensitive clinical tools and outcome measures are needed, especially in adult patients undergoing treatment, in which the expected clinical response is a mild improvement or stabilization of disease progression.

Methods

Here, we describe a new functional motor scale specifically designed for evaluating the endurance dimension for the upper and lower limbs in adult SMA patients.

Results

The scale was first tested in eight control healthy subjects and then validated in ten adult SMA patients, proving intra- and inter-observer reliability. We also set up an evaluation protocol by using wearable devices including surface EMG and accelerometer.

Conclusions

The endurance evaluation should integrate the standard clinical monitoring in the management and follow-up of SMA adult patients.

Digital health and Clinical Patient Management System (CPMS) platform utility for data sharing of neuromuscular patients: the Italian EURO-NMD experience

BACKGROUND

The development of e-health technologies for teleconsultation and exchange of knowledge is one of the core purposes of European Reference Networks (ERNs), including the ERN EURO-NMD for rare neuromuscular diseases. Within ERNs, the Clinical Patient Management System (CPMS) is a web-based platform that seeks to boost active collaboration within and across the network, implementing data sharing. Through CPMS, it is possible to both discuss patient cases and to make patients' data available for registries and databases in a secure way. In this view, CPMS may be considered a sort of a temporary storage for patients' data and an effective tool for data sharing; it facilitates specialists' consultation since rare diseases (RDs) require multidisciplinary skills, specific, and outstanding clinical experience. Following European Union (EU) recommendation, and to promote the use of CPMS platform among EURO-NMD members, a twelve-month pilot project was set up to train the 15 Italian Health Care Providers (HCPs). In this paper, we report the structure, methods, and results of the teaching course, showing that tailored, ERN-oriented, training can significantly enhance the profitable use of the CPMS.

RESULTS

Throughout the training course, 45 professionals learned how to use the many features of the CPMS, eventually opening 98 panels of discussion-amounting to 82% of the total panels included in the EURO-NMD. Since clinical, genetic, diagnostic, and therapeutic data of patients can be securely stored within the platform, we also highlight the importance of this platform as an effective tool to discuss and share clinical cases, in order to ease both case solving and data storing.

CONCLUSIONS

In this paper, we discuss how similar course could help implementing the use of the platform, highlighting strengths and weaknesses of e-health for ERNs. The expected result is the creation of a "map" of neuromuscular patients across Europe that might be improved by a wider use of CPMS.

Cardiac magnetic resonance findings and prognosis in type 1 myotonic dystrophy

BACKGROUND

Cardiac involvement is a major determinant of prognosis in type 1 myotonic dystrophy (DM1), but limited information is available about myocardial remodeling and tissue changes. The aim of the study was to investigate cardiac magnetic resonance (CMR) findings and their prognostic significance in DM1.

METHODS

We retrospectively identified all DM1 patients referred from a neurology unit to our CMR laboratory from 2009 to 2020.

RESULTS

Thirty-four patients were included (aged 45 ± 12, 62% male individuals) and compared with 68 age-matched and gender-matched healthy volunteers (43 male individuals, age 48 ± 15 years). At CMR, biventricular and biatrial volumes were significantly smaller (all P < 0.05), as was left ventricular mass (P < 0.001); left ventricular ejection fraction (LVEF) and right ventricular ejection fraction (RVEF) were significantly lower (all P < 0.01). Five (15%) patients had a LVEF less than 50% and four (12%) a RVEF less than 50%. Nine patients (26%) showed mid-wall late gadolinium enhancement (LGE; 5 ± 2% of LVM), and 14 (41%) fatty infiltration. Native T1 in the interventricular septum (1041 ± 53 ms) was higher than for healthy controls (1017 ± 28 ms) and approached the upper reference limit (1089 ms); the extracellular volume was slightly increased (33 ± 2%, reference <30%). Over 3.7 years (2.0-5.0), 6 (18%) patients died of extracardiac causes, 5 (15%) underwent device implantation; 5 of 21 (24%) developed repetitive ventricular ectopic beats (VEBs) on Holter monitoring. LGE mass was associated with the occurrence of repetitive VEBs (P = 0.002). Lower LV stroke volume (P = 0.017), lower RVEF (P = 0.016), a higher LVMi/LVEDVI ratio (P = 0.016), fatty infiltration (P = 0.04), and LGE extent (P < 0.001) were associated with death.

CONCLUSION

DM1 patients display structural and functional cardiac abnormalities, with variable degrees of cardiac muscle hypotrophy, fibrosis, and fatty infiltration. Such changes, as evaluated by CMR, seem to be associated with the development of ventricular arrhythmias and a worse outcome.

The role of magnetic resonance imaging in the diagnostic work-out of myopathies: differential diagnosis between inflammatory myopathies and muscular dystrophies

OBJECTIVES

The differential diagnosis between idiopathic inflammatory myopathies (IIM) and muscular dystrophies (MD) may be challenging. We analysed the potential role of muscular magnetic resonance imaging (MRI) in the differential diagnosis between IIM and MD.

METHODS

MRI of patients (91 IIM and 43 MD), studied with a standardised protocol, have been collected. The presence of oedema, muscular atrophy and intramuscular adipose changes were evaluated. Moreover, we computed a composite score for each MRI item to better discriminate between the two diseases.

RESULTS

Oedema was significantly more prevalent in IIM compared with MD in pelvis muscles (p<0.001), anterior lodge and medial lodges (p=0.044) of the thighs. Adipose infiltration/substitution and muscular atrophy were more prevalent in MD, in particular adipose tissue was prevalent in all the compartments of the thighs (p<0.05), atrophy was prevalent at the thighs and pelvis muscles (p<0.001). The probability of IIM increased with higher oedema score and decreased with higher atrophy and intramuscular adipose infiltration/substitution scores.

CONCLUSIONS

A different distribution of muscular involvement between IIM and MD has been identified. Muscular MRI may be useful in the differential diagnosis, potentially reducing the number of muscular biopsies that may be reserved only for doubtful cases.

1099 ERGOREFLEX SENSITIVITY IS ASSOCIATED WITH CARDIAC INVOLVEMENT IN BECKER MUSCULAR DYSTROPHY

Background and aims

Becker muscular dystrophy (BMD) is a X-linked recessive inherited skeletal myopathy due to dystrophin deficiency ensuing in a variable phenotype characterized by slowly progressing muscle weakness and, often, the development of dilated cardiomyopathy. The relationship between muscle and cardiac involvement in BMD is yet to be clarified. We aimed to assess the association between ergoreflex sensitivity, a marker of skeletal muscle work regulating ventilatory and autonomic responses to exercise, and cardio-muscular involvement in BMD.

Methods

Fifteen male BMD patients (median age 37 years [25-42]) underwent a comprehensive evaluation including ECG, biohumoral assessment (high sensitivity troponin T/I [hs-TnT/I], natriuretic peptides, soluble suppression of tumorigenesis 2 [sST2], catecholamines, creatine phosphokinase [CPK], myoglobin), cardiac magnetic resonance (CMR), and ergoreflex determination. Muscular phenotype was distinguished into “classic” (proximal weakness affecting the shoulders and pelvis with waddling gait) or “mild”. Cardiac involvement was defined based on the presence of late gadolinium enhancement (LGE) at CMR. Ergoreflex sensitivity was calculated as the percentage of the ventilatory response to a handgrip exercise maintained by circulatory occlusion through the inflation of a forearm tourniquet (clamp) during the third minute of recovery compared with the third minute of recovery without clamp: [(Rec∕Ex) clamp − (Rec∕Ex) no clamp]∗100, where Ex is the mean ventilation during the last 30 s of exercise, Rec the mean ventilation during the last 30 s of the third minute of recovery.

Results

Ten patients (67%) had a “classic” muscular phenotype. Nine patients (60%) had LGE at CMR (median number of segments 9 [6-12]). The percentage of patients with cardiac involvement was not different between those with “classic” or mild muscular phenotype. Patients with cardiac involvement had higher ergoreflex sensitivity (24% [8-38] vs. 4% [0-24], p=0.036), hs-TnI (9.8 ng/L [5.9-14.5] vs. 2.1 ng/L [1.7-4.5], p=0.018), and hs-TnT (24 ng/L [20-35] vs. 11 ng/L [5-20], p=0.012), but did not show significant differences in terms of cardiac chamber size or systolic function compared to those without LGE. Ergoreflex sensitivity correlated with biomarkers of both cardiac (hs-TnI, rho=0.654, p=0.008; hs-TnT, rho=0.529, p=0.043; sST2, rho=0.654, p=0.009) and muscular damage (CPK, rho=0.645, p=0.009), as well as with the number of LGE segments (rho=0.583, p=0.022). No difference in ergoreflex sensitivity was detected in patients with “classic” versus mild muscular phenotype.

Conclusions

In BMD, there is no relationship between cardiac involvement and the muscular phenotype. Nonetheless, cardiac involvement in BMD is characterized by enhanced ergoreflex sensitivity, which is associated with biomarkers of both cardiac and muscular damage.

Frailties and critical issues in neuromuscular diseases highlighted by SARS-CoV-2 pandemic: how many patients are still "invisible"?

Almost 90% of neuromuscular diseases (NMDs) are classified as rare diseases, defined as conditions affecting less than 5 individuals in 10.000 (0.05%). Their rarity and diversity pose specific challenges for healthcare and research. Epidemiological data on NMDs are often lacking and incomplete. The COVID-19 pandemic has further highlighted the management difficulties of NMDs patients and the necessity to continue the program of implementation of standard of care. This article summarizes the Italian experience during pandemic.

Therapeutic opportunities and clinical outcome measures in Duchenne muscular dystrophy

INTRODUCTION

Duchenne muscular dystrophy (DMD) is a devastatingly severe genetic muscle disease characterized by childhood-onset muscle weakness, leading to loss of motor function and premature death due to respiratory and cardiac insufficiency.

DISCUSSION

In the following three and half decades, DMD kept its paradigmatic role in the field of muscle diseases, with first systematic description of disease progression with ad hoc outcome measures and the first attempts at correcting the disease-causing gene defect by several molecular targets. Clinical trials are critical for developing and evaluating new treatments for DMD.

CONCLUSIONS

In the last 20 years, research efforts converged in characterization of the disease mechanism and development of therapeutic strategies. Same effort needs to be dedicated to the development of outcome measures able to capture clinical benefit in clinical trials.

Prediction of complex gastroschisis: The evolution of therapeutic techniques and their relation with fetal sonographic features

BACKGROUND

To analyze prenatal ultrasound (US) markers to predict treatment and adverse neonatal outcome in fetal gastroschisis.

METHODS

It was conducted a retrospective single-center study considering all pregnancies with isolated gastroschisis that were treated in our department between 2008 and 2020. 17 US markers were analyzed. Moreover, the association between prenatal ultrasound signs and neonatal outcomes was analyzed: need of bowel resection, techniques of reduction, type of closure, adverse neonatal outcomes, time to full enteral feeding, length of total parenteral nutrition and length of hospitalization.

RESULTS

The analysis included 21 cases. We found significant associations between intestinal dilation (≥10 mm) appeared before 30 weeks of gestation and the need of bowel resection (p = 0.001), the length of total parenteral nutrition (p = 0,0013) and the length of hospitalization (p = 0,0017). Intrauterine growth restriction (IUGR) is a risk factor for serial reduction (p = 0,035). There were no signs significantly associated with the type of closure. Hyperbilirubinemia is related with gestational age (GA) at the diagnosis of intra-abdominal bowel dilation (IABD) (p = 0.0376) and maximum IABD (p = 0.05). All newborns with sepsis had echogenic loops in uterus (p = 0.026). The relation between the GA at delivery and the GA at the extra-abdominal bowel dilation (EABD)≥10 mm was r = 0.70.

CONCLUSION

We showed the significant role of the early presence of bowel dilation in predicting intestinal resection and adverse outcomes. All IUGR fetuses needed staged reduction through the silo-bag technique. The echogenic bowel was related to neonatal sepsis, while IABD was associated with hyperbilirubinemia.

Anti-HMGCR antibodies and asymptomatic hyperCKemia. A case report

Anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) related myositis is a form of immune-mediated necrotizing myopathy (IMNM). Anti-HMGCR autoantibodies target HMGCR, a glycoprotein linked to the endoplasmic reticulum implied in the cholesterol synthesis pathway, and exert a pathogenic effect on skeletal muscle cells. More than 60% of patients affected by HMGCR-related myositis shares statin-exposure in their medical history. Patients commonly experience CK levels elevation, myalgia, muscle weakness and soreness at variable extent, which manifest acutely or sub acutely with a progressively worsening course, in some cases mimicking limb-girdle muscular dystrophies (LGMD) phenotype and treatment is based on an immunosuppressive strategy. Here we present the peculiar case of a previously statins-exposed 72 y.o. asymptomatic man with persistent moderate hyperCKemia and high levels of anti-HMGCR, in which pharmacotherapy has not been initiated yet, while a wait-and-see approach has been adopted instead.

Next-generation sequencing application to investigate skeletal muscle channelopathies in a large cohort of Italian patients

Non-dystrophic myotonias and periodic paralyses are a heterogeneous group of disabling diseases classified as skeletal muscle channelopathies. Their genetic characterization is essential for prognostic and therapeutic purposes; however, several genes are involved. Sanger-based sequencing of a single gene is time-consuming, often expensive; thus, we designed a next-generation sequencing panel of 56 putative candidate genes for skeletal muscle channelopathies, codifying for proteins involved in excitability, excitation-contraction coupling, and metabolism of muscle fibres. We analyzed a large cohort of 109 Italian patients with a suspect of NDM or PP by next-generation sequencing. We identified 24 patients mutated in CLCN1 gene, 15 in SCN4A, 3 in both CLCN1 and SCN4A, 1 in ATP2A1, 1 in KCNA1 and 1 in CASQ1. Eight were novel mutations: p.G395Cfs*32, p.L843P, p.V829M, p.E258E and c.1471+4delTCAAGAC in CLCN1, p.K1302R in SCN4A, p.L208P in ATP2A1 and c.280-1G>C in CASQ1 genes. This study demonstrated the utility of targeted next generation sequencing approach in molecular diagnosis of skeletal muscle channelopathies and the importance of the collaboration between clinicians and molecular geneticists and additional methods for unclear variants to make a conclusive diagnosis.

Estimating the impact of COVID-19 pandemic on services provided by Italian Neuromuscular Centers: an Italian Association of Myology survey of the acute phase

Introduction

Since February 2020, the outbreak of COVID-19 in Italy has forced the health care system to undergo profound rearrangements in its services and facilities, especially in the worst-hit areas in Northern Italy. In this setting, inpatient and outpatient services had to rethink and reorganize their activities to meet the needs of patients during the “lockdown”. The Italian Association of Myology developed a survey to estimate the impact of these changes on patients affected by neuromuscular disorders and on specialized neuromuscular centers during the acute phase of COVID-19 pandemic.

Methods

We developed an electronic survey that was sent to neuromuscular centers affiliated with the Italian Association of Myology, assessing changes in pharmacological therapies provision, outpatient clinical and instrumental services, support services (physiotherapy, nursing care, psychological support) and clinical trials.

Results

40% of surveyed neuromuscular centers reported a reduction in outpatient visit and examinations (44.5% of centers in Northern regions; 25% of centers in Central regions; 50% of centers in Southern regions). Twenty-two% of centers postponed in-hospital administration of therapies for neuromuscular diseases (23.4% in Northern regions; 13.0% in Central regions; 20% in Southern regions). Diagnostic and support services (physiotherapy, nursing care, psychological support) were suspended in 57% of centers (66/43/44% in Northern, Central and Southern centers respectively) Overall, the most affected services were rehabilitative services and on-site outpatient visits, which were suspended in 93% of centers. Strategies adopted by neuromuscular centers to overcome these changes included maintaining urgent on-site visits, addressing patients to available services and promoting remote contact and telemedicine.

Conclusions

Overall, COVID-19 pandemic resulted in a significant disruption of clinical and support services for patients with neuromuscular diseases. Despite the efforts to provide telemedicine consults to patients, this option could be promoted and improved further. A close collaboration between the different neuromuscular centers and service providers as well as further implementation of telehealth platforms are necessary to ensure quality care to NMD patients in the near future and in case of recurrent pandemic waves.

The prognostic value of antenatal ultrasound in cases complicated by fetal ovarian cysts

OBJECTIVE

Ovarian cysts are relatively common prenatal findings in female fetuses. The aim of this study is to evaluate the ability of antenatal ultrasound in predicting spontaneous regression or a need for surgery.

DESIGN

All cases of fetal ovarian cysts treated in our Department between 2007 and 2016 were included. Patients underwent a sonographic monitoring in utero and after birth until spontaneous or surgical resolution. Subjects were divided into two groups according to their postnatal management. Receiver-operating characteristics (ROC) curves were used to test the predictive ability for postnatal surgery of the cyst's mean and maximum diameters; their optimal cut off points were also determined.

RESULTS

38 cases of antenatally-detected fetal ovarian cysts were included. 12/38 cases underwent surgery (Group A). 26/38 cases were resolved spontaneously (Group B). Cyst size of those which were surgically excised significantly differed from those that regressed spontaneously. ROC curve pointed to 45 mm and 47 mm as optimal cut off points for the mean and the maximum cystic diameters, respectively.

CONCLUSIONS

Cyst size and echo-structure seemed good predictors for prognosis after birth. The optimal cut off points of the cysts mean and maximum diameters in predicting postnatal surgery have been identified as 45 mm and 47 mm, respectively.

Moderate and severe fetal pyelectasis: Correlation between prenatal aspects and postnatal outcome

BACKGROUND

Renal pelvic dilatation (RPD) is a frequent finding in fetal ultrasound. The aim of the study is to correlate the prenatally detected moderate and severe pyelectasis with the postnatal outcome.

METHODS

A retrospective analysis involving 90 cases of prenatally detected moderate and severe RPD referred to our prenatal diagnosis centre with 18 months of urological follow-up. Prenatal ultrasound was correlated with postnatal renal function, assessed by plasmatic creatinine and/or renal scintigraphy performed before surgery.

RESULTS

Cases were divided between two groups according to postnatal management: group A including 35 newborns (38.9%) that needed surgical treatment and group B with 55 patients (61.1%) who were managed conservatively. The group A presented higher median RPD (18 mm, IQR 12-25 mm) compared to the group B (11 mm, IQR 10-14 mm). The most common anomaly detected within group A was pelvi-ureteric junction (PUI) obstruction (43%). Within group B 32 cases (58%) showed spontaneous resolution of hydronephrosis during postnatal follow up. In case of moderate pyelectasis the risk of postnatal surgery was 25% and raised to 60% for severe RPD. In our study, 29 newborns showed pathologic scintigraphies: 25 required surgery while 4 did not find indication for surgery due to ipsilateral renal function irreversible damage. 6 patients had high creatinine level (>0.6 mg/dl). 35 cases out of 90 (39%) developed monolateral irreversible renal function impairment.

CONCLUSION

Moderate and severe RPD are often correlated with postnatal renal damage, therefore a close multidisciplinary follow-up is required. Prenatal scanning is highly predictive of postnatal outcome and can address properly the prenatal counseling.

Mechanistic investigations of the asymmetric hydrosilylation of ketimines with trichlorosilane reveals a dual activation model and an organocatalyst with enhanced efficiency

Mechanistic investigations of a catalyst used for the asymmetric hydrosilylation have revealed a ‘dual activation’ model and catalyst that maintains its performance at 0.01 mol% loading.

Italian multicenter survey on laparoscopic treatment of gastro-esophageal reflux disease in children

BACKGROUND

Skepticism is still present today about the laparoscopic treatment of gastro-esophageal reflux (GER) in children. We present the prospective experience and short-term results of eight Italian pediatric surgical units.

METHODS

We included all the children with complicated GER, operated after January 1998 by single surgeons from eight different centers. Diagnostic aspects, type of fundoplication, and complications were considered. All the patients were followed for a minimum period of 6 months in order to detect complications or recurrences.

RESULTS

288 children were prospectively included. Mean age was 4.8 years (3 m-14 y). Nissen fundoplication was done in 25%, floppy Nissen in 63%, Toupet in 1.7%, and anterior procedures (Lortat Jacob, Thal) in 10%. Gastrostomy was associated, if neurological impairment or feeding disorders were present. Mean follow-up was 15 months and reoperation was necessary in 3.8% of cases.

CONCLUSIONS

This experience underlines that minimal invasive access surgery in children is safe and that the laparoscopic approach is considered in eight centers the golden standard for surgical repair of gastro-esophageal reflux disease maintaining the same indications and techniques of the open approach.

[The laparoscopic treatment of Hirschsprung's disease]

Swenson's procedure, first described in 1948 for Hirschsprung's disease, consists in resection of aganglionic intestine and distal colo-anal anastomosis provided a precise dissection of extra peritoneal rectum. Potential jeopardy of pelvic vessels and nerves stimulated alternative surgical techniques to prevent complications on bladder and genital function. We performed in laparoscopy Swenson's procedure after Toupet, taking advantage from closer view and magnification of this technique, in a 15 months girl. Laparoscopy simplified and made safer pelvic dissection and resulted in a better postoperative period and cosmetic outcome.

Adequacy of paracardial dissection in subtotal versus total gastrectomy

Right and left paracardial dissection represents an obligatory step in gastrectomy for gastric cancer of the lower half of the stomach because a second-level lymphadenectomy is part of the radical surgery for malignancy at this site. Whereas right and left paracardial dissection is easily accomplished during total gastrectomy, there is doubt as to whether subtotal gastrectomy achieves the same radical clearance of these groups of lymph nodes. This study therefore compared the number of lymph nodes dissected and the frequency of metastases in these compartments in 14 patients undergoing total gastrectomy and 22 submitted to subtotal gastrectomy. The mean number of lymph nodes dissected in the right paracardial compartment was 7.1 per patient undergoing total gastrectomy and 6.7 per patient in subtotal gastrectomy (P = 0.7). The mean numbers of left paracardial lymph nodes dissected in total and subtotal gastrectomy were 3.4 and 4.1 per patient respectively (P = 0.3). These data show that the same degree of radical clearance can be achieved in these nodal compartments, irrespective of the extent of gastric resection.

[Glypressin and emergency sclerotherapy, deferred emergency shunt (Warren, portacaval, mesocaval): new tactics in the treatment of severe hemorrhage by esophagogastric varices in cirrhotic patients]

Transplenic decompression of esophageal varices by distal splenorenal shunt according to Warren (DSRS) aims to a selective detention of the esophago-gastric varices, also assuring an adequate portal perfusion and hypertensive state of the porto-mesenteric district. The DSRS though, should and must not be performed in emergency as a high mortality rate is registered in all cases of emergency porto-systemic derivations. A mortality risk is reported even during endoscopic sclerosis if performed in emergency compared to the elective procedure. The scope of our study was to test the validity of a new approach of the hemorrhagic cirrhotic patient: the end point was to stop the bleeding with Glypressin and deferred sclerotherapy, associating a selective shunt at 40-60 days. Out of 32 patients with esophago-gastric variceal bleeding, 8 were selected also for derivative surgery. Results show Glypressin as the first and best therapeutic approach. The drug in many cases stops bleeding or at least reduces the blood loss allowing an easier endoscopic sclerosis. Further sclerosis and/or surgical therapy may assure variceal eradication.
