Thoracoscopy versus thoracotomy for congenital lung malformations treatment: A single center experience.

INTRODUCTION: Our aim is to compare thoracoscopy to thoracotomy in the treatment of congenital lung malformations (CLM) in children. MATERIALS AND METHODS: We report a retrospective monocentric cohort study. Patients treated at our Center for CLM (1991-2020) were divided in two groups: patients treated with video-assisted thoracoscopic surgery (VATS) and open thoracotomy (OT). Characteristics of the two groups were compared through statistical analysis (GraphPad Prism7). A p value less than .05 was considered statistically significant. RESULTS: One hundred six patients were included: 58 in VATS group, 48 in OT group. Prenatal diagnosis was possible in 73.6%. The most frequent surgical procedures were lobectomy (43.4%) and sequestrectomy (22.6%). All VATS patients underwent lung exclusion, mostly by endobronchial blocker (69%). Mean operative time was 146.1 min (±52.04 SD) in VATS and 159.2 (±46.53 SD) in OT (p = .1973). Conversion to OT was necessary in 20.6% of VATS patients, but decreased in the last 5 years (6.2%). There were not any intraoperative complication. Respectively in VATS and OT group, length of stay (LOS) was 4.5 days ± 3.6 SD versus 7.7 ± 3.4 SD (p < .0001), chest tube duration 2.8 days ± 3.4 SD versus 3.7 ± 2.4 SD (p < .0001), antibiotic treatment duration 3.7 days ± 4.7 SD versus 5 ± 2.6 SD (p = .1196). Postoperative complications were described in 22.6%. The commonest histological diagnosis (40.6%) was congenital pulmonary airway malformation. CONCLUSION: VATS resulted a feasible, effective and safe technique. Operative time and postoperative complications were similar in VATS and OT groups. VATS conversion rate decreased in time. VATS had a statistically significant shorter LOS and chest tube duration.

Biliary atresia: 20-40-year follow-up with native liver in an Italian centre.

INTRODUCTION: Biliary atresia (BA) represents the leading indication for liver transplantation in childhood. Only few studies reported the outcome of patients who survived more than 20 years on their native liver, and up to date there are no Italian data available. We reported our 40-year single centre experience with long-term follow-up of BA patients. MATERIALS AND METHODS: All consecutive patients who underwent Kasai portoenterostomy (KPE) for BA managed at our Institution between 1975 and 1996 were retrospectively reviewed. Native liver (NLS) and overall survival (OS) were analyzed with Kaplan-Meyer curves and LogRank test. A p value of <.05 was regarded as significant. Quality of life of patients currently surviving with their native liver was assessed through a quality of life questionnaire. RESULTS: During the 22-year period of the study 174 patients underwent surgery (median age 60 days). Clearance of jaundice at 6 months from surgery was achieved in 90 patients (51.7%). NLS was 41% at 5 years, 32% at 10 years, 17.8% at 20 years and 14.9% at 40 years. Cholangitis was recorded in 32%, hepatocellular carcinoma in 0.5%. Twenty-six patients (14.9%) survived with their liver more than 20 years; 84.6% had normal serum bilirubin level and 23% had esophageal varices. Quality of life was comparable with the healthy Italian population in all but one patient. CONCLUSIONS: Our Italian experience confirms KPE represents the cornerstone of treatment for children with BA. Multidisciplinary and meticulous lifelong post-operative follow-up should be guaranteed for these patients because of the possibility of late-onset cholangitis, portal hypertension, hepatic deterioration and liver malignant tumors. TYPE OF THE STUDY: retrospective case series. LEVEL OF EVIDENCE: IV.

Endoscopic management of sigmoid volvulus in children.

Sigmoid volvulus (SV) is extremely uncommon in children and is usually associated with a long-standing history of constipation or pseudo-obstruction. An early diagnosis and management are crucial in order to prevent the appearance of hemorrhagic infarction of the twisted loop, avoiding further complications such as necrosis, perforation and sepsis. In patients with no evidence of peritonitis or ischemic bowel, treatment starts with resuscitation and detorsion of the SV, accomplished by means of sigmoidoscopy and concomitant rectal tube placement. The bowel is then prepared and surgery is undertaken electively during the same hospitalization. We report a detailed review of the literature focusing on technical details, risks and benefits of endoscopic management of SV in childhood.
