Procedure-related registries in general surgical practice offer a platform for prospective trials, the pooling of data, and detailed outcome analysis. Recommendations by the Idea, Development, Exploration, Assessment, and Long-term follow-up (IDEAL) collaboration and Outcome4Medicine have further improved the uniform reporting of complications and adverse events. In the pediatric surgical network, disease-specific registries for rare and inherited congenital anomalies are gaining importance, fostering international collaborations on studies of low-incidence diseases. However, to date, reporting of complications in the pediatric surgical registries has been inconsistent. Therefore, the European Reference Network for Rare Inherited and Congenital Anomalies (ERNICA) recently endorsed the validation of the first severity grading system for children. The planned reform of the European Paediatric Surgical Audit (EPSA) registry, which includes the implementation of the Clavien–Madadi classification, represents a further effort to establish uniform outcome reporting. This article provides an overview of experiences with surgical registries and complication reporting, along with the potential application of this knowledge to future pediatric surgical practice.

Severity grading systems for complications in surgical patients have been used since 1992. An increasing assessment of these instruments in pediatric surgery is also noticed, without their validation in children. To analyze the current practice, we performed a literature review with focus on the assessment and grading of complications. The review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Studies reporting on postoperative complications as a primary or secondary endpoint using a severity grading system were included. Definition for simple adverse events, classification systems used, and the time horizon of postoperative documentation were analyzed. A total of 566 articles were screened, of which 36 met the inclusion criteria. About 86.1% of the papers were retrospective and 13.9% prospective analyses. None of the studies were prospective-randomized trials. Twenty (55.6%) studies did not include a definition of adverse events, whereas the remaining 16 (44.4%) showed variations in their definitions. All studies applied the Clavien-Dindo classification, whereas five (13.9%) additionally used the Comprehensive Complication Index. One study compared alternative grading instruments with the Clavien-Dindo classification, without demonstrating the superiority of any classification in pediatric surgery. Twenty-two studies (61.1%) did not report the time horizon of perioperative complication documentation, while 8 studies (22.2%) used 30 days and 6 studies (16.7%) used 3 months of postoperative documentation. Definition and classification of postoperative complications are inconsistent in the pediatric surgical literature. Establishment of a standardized protocol is mandatory to accurately compare outcome data. [ABSTRACT FROM AUTHOR]

Background:  Numerous studies from Asian countries, including large collectives, have reported excellent results after laparoscopic resection of choledochal malformation (CM). However, the role of laparoscopic CM resection is still controversial outside Asia. We aimed to analyze the outcome of laparoscopic CM resection in our institution and to compare our outcome with the data reported in the literature.Methods:  All patients who underwent laparoscopic CM resection in our pediatric surgical department from 2002 to 2019 were retrospectively analyzed for surgical details and postoperative complications, which were graded according to the Clavien-Dindo classification. A systematic literature search identified all reports on over 10 cases of laparoscopic pediatric CM resection and surgical details, follow-up, and complication rates were extracted.Results:  Fifty-seven patients (72% female) with a mean age of 3.6 + 4.1 years underwent laparoscopic CM resection in our department. Conversion rate was 30%. Total complication rate was 28%. The rate of major complications (Clavien-Dindo grade III or more) was 16% and included stricture of the biliodigestive or enteric anastomosis (n = 4), adhesive ileus (n = 3), portal vein thrombosis (n = 1), and recurrent cholangitis with consecutive liver transplantation (n = 1). With increasing experience, complication rates decreased. The majority of publications on laparoscopic CM resections originated from Asia (n = 36) and reported on low complication rates. In contrast, publications originating from non-Asian countries (n = 5) reported on higher complications following laparoscopic CM resection.Conclusion:  Our data indicate that laparoscopic CM resection can be safely performed. The learning curve in combination with the low incidence calls for a centralization of patients who undergo laparoscopic CM resection. There seems to be a discrepancy on complications rates reported from Asian and non-Asian countries following laparoscopic CM resection. [ABSTRACT FROM AUTHOR]

Background Postoperative adverse events may be associated with substantial morbidity and mortality. Numerous severity grading systems for these events have been introduced and validated but have not yet been systematically applied in paediatric surgery. This study aimed to analyse the advantages and disadvantages of these classifications in a paediatric cohort. Methods Unexpected events associated with interventional or organizational problems in the department of paediatric surgery during 2017–2020 were prospectively documented daily for all children. Events were classified according to the Clavien–Dindo grading system during monthly morbidity and mortality conferences. All events were also classified according to five additional grading systems: T92, contracted Accordion, expanded Accordion, Memorial Sloan Kettering Cancer Center, and Comprehensive Complication Index (CCI)®. Results Of 6296 patients, 673 (10.7 per cent) developed adverse events and 240 (35.7 per cent) had multiple events. Overall, 1253 adverse events were identified; of these, 574 (45.2 per cent) were associated with surgical or medical interventions and 679 (54.8 per cent) included organizational problems. The grading systems demonstrated high overall correlation (r pears = 0.9), with minor differences in sentinel events. The Clavien–Dindo classification offered the most detailed assessment. However, these details had only limited additional value. The CCI® scores were correlated with other grading systems (r pears = 0.9) and were useful in analysing multiple events within individual patients. Conclusion Grading systems demonstrated similar scoring patterns for minor and sentinel events, with none being superior for unexpected events in children. However, the CCI® can be a major improvement in assessing morbidity in patients with multiple events. Its use is therefore recommended in prospective studies on paediatric surgery.

The use of minimally invasive surgery (MIS) in pediatric patients has increased over the past decades. The process of mastering a new procedure is termed the learning curve, during which the ability to operate increases but poorer outcomes are produced. We aim to analyze the current evidence on learning curves in pediatric MIS and evaluate its impact on patient's clinical outcomes. A systematic literature search was performed for studies listed on PubMed that reported on the learning curve for MIS surgical procedures. Studies were included if they stated the number of procedures required to reach a consistency in outcomes or if they compared outcomes between early and late period of MIS experience regarding the endpoints operative time, conversions, and intra-/postoperative complications. A total of 22 articles reporting on 11 surgical procedures were included in the study. Most authors reported a significant decrease in operative time as well as peri- and postoperative complications with increasing experience of the surgeon. Complications ranged from minor to major, the latter being especially severe for patients receiving pyloromyotomy (5-7% higher risk of mucosal perforation), esophageal atresia repair (15% higher leakage rate and 19-77% higher stenosis rate), or Kasai portoenterostomy (26-35% more liver transplants in the first year after surgery) during the learning curve period. Pediatric MIS comes with a considerable learning curve that may have a significant impact on the patient's clinical outcomes. Efforts should be made to minimize the effect of the learning curve on the patients. [ABSTRACT FROM AUTHOR]

Introduction:  Management strategies for large omphaloceles remain controversial. In this study, we discuss the use of GRAVITAS (gravitational autoreposition sutures), the method used at our institution when successful primary closure is deemed questionable. Patient's primary clinical course and long-term outcomes were analyzed.Materials and Methods:  This is a single-center retrospective analysis of all consecutive patients with omphaloceles treated between 1997 and 2018. Decision for GRAVITAS was made when the defect was estimated too large for primary closure. Traction sutures were placed in the fascia surrounding the defect and then suspended from the top of the incubator to allow gravitational autoreposition of the herniated organs. Ventilation and muscle relaxation were maintained until secondary closure, which was performed after the obtruding viscera had been reduced by repeated adjustment of the suture's tension. Data are presented as mean ± standard deviation.Results:  Out of 49 patients with omphaloceles, 12 were treated with GRAVITAS, 33 underwent primary closure, and 4 were treated using Schuster's technique. Mean time to secondary closure after GRAVITAS was 7 ± 10 days. In nine of the patients who had isolated omphalocele, secondary closure was achieved after 4 ± 2 days. Ventilation time was 5 ± 2 days, and time to full feeds was 18 ± 16 days. In three patients (one with Fallot's tetralogy, one with Cantrell's pentalogy, and one with lung hypoplasia), abdominal closure was achieved after 17 ± 15 days. Due to cardiorespiratory comorbidity, ventilation time was >30 days. Five patients received initial closure of the skin and secondary fascial closure after 18 ± 15 months. One patient with prior fascial closure underwent later repair of an abdominal wall hernia. During follow-up (30 ± 35 months), one patient with gastrointestinal obstruction due to adhesions required laparotomy, and one patient with gastroesophageal reflux disease underwent fundoplication.Conclusion:  GRAVITAS is a feasible method for staged closure of large omphaloceles when successful primary closure is deemed questionable.

Introduction:  A decrease in the anteroposterior diameter (APD) of the renal pelvis on ultrasound has been postulated to be indicative of sufficient pelvic drainage after pyeloplasty. Traditionally, pyeloplasty is combined with a reduction of the renal pelvis. We have recently demonstrated that resection of the pelvis during pyeloplasty is not necessary. We aimed to evaluate the efficacy of ultrasound APD measurements during follow-up to identify sufficient pelvic drainage in these patients.Materials and Methods:  Data from children (0-16 years) who underwent pelvis-sparing pyeloplasty in our institution from 2007 to 2018 were analyzed retrospectively. We included only those patients for whom pre- and postoperative ultrasound and renal scan data were available. Patients with a decrease versus patients with an increase in APD were analyzed with regard to urinary drainage and reoperation.Results:  Seventy-three patients who underwent follow-up at a mean of 3 months after operation were included; 61 showed a decrease in APD. Renal scan showed sufficient urinary drainage in 58 of them, with none requiring reoperation. Twelve patients had an increase in APD. Six of these showed free urinary drainage on renal scan; another six showed insufficient drainage, of whom five required reoperation. The positive predictive value of a decrease in APD was 1, and the negative predictive value of increase in APD was 0.42.Conclusion:  To our knowledge, this is the first study evaluating the efficacy of ultrasound measurements to identify patients with decompensated urinary drainage during early follow-up after pyeloplasty with pelvis sparing. Post- versus preoperative decrease in renal pelvis diameter appears to be sufficient to rule out recurrence of obstruction. Renal scan seems to be indicated only in cases with post- versus preoperative increase in the APD of the renal pelvis on ultrasound. [ABSTRACT FROM AUTHOR]

Surgeons are obligated to assure the highest quality of care for their patients, and part of this process is regular in-house audits to review their results and outcomes. While numerous projects focus on the patients' outcome after (serious) adverse events, the surgeon's perspective and their coping with those events is still neglected in the literature. [5][6][7] This strategy is the keystone to prepare for (serious) adverse events for the morbidity and mortality conferences, which, if necessary, result in amendments of the standard operating procedures (SOP) based on the discussions.

Previous research has confirmed that patients with choledochal cyst have an elevated risk of cholangiocarcinoma and gallbladder carcinoma. Current data suggest a risk of malignancy of 6 to 30% in adults with choledochal cyst. Malignancy has also occasionally been identified in children and adolescents. Multiple factors, including the age of the patient, cyst type, histological findings, and localization, have an impact on the prognosis. Information on long-term outcomes after cyst excision is limited. However, recent data suggest a lifelong elevated risk of up to 4% of cancer development following operation. This paper presents a review of the literature on cancer in patients with choledochal cyst before and after excision. A postoperative follow-up concept that consists of annual controls of CA19-9 and abdominal ultrasound is introduced. [ABSTRACT FROM AUTHOR]

Aim:  Surgical expertise and advances in technical equipment and perioperative management have led to enormous progress in survival and morbidity of patients with esophageal atresia (EA) in the last decades. We aimed to analyze the available literature on surgical outcome of EA for the past 80 years.Materials and Methods:  A PubMed literature search was conducted for the years 1944 to 2017 using the keywords "esophageal/oesophageal atresia," "outcome," "experience," "management," and "follow-up/follow up." Reports on long-gap EA only, non-English articles, case reports, and reviews without original patient data were excluded. We focused on mortality and rates of recurrent fistula, leakage, and stricture.Results:  Literature search identified 747 articles, 118 manuscripts met the inclusion criteria. The first open end-to-end anastomosis and fistula ligation was reported in 1941. Thoracoscopic fistula ligation and primary anastomosis was performed first in 2000. Reported mortality rate decreased from 100% before 1941 to 54% in 1950 to 1959, 28% in 1970 to 1979, 16% in 1990 to 1999, and 9% nowadays. Rates of recurrent fistula varied over time between 4 and 9%. Leakage rate remained stable between 11 and 16%. However, stricture rate increased from 25 to 38%.Conclusion:  Including a full range of articles reflecting the heterogeneity of EA, mortality rate significantly decreased during the course of 80 years. Along with the decrease in mortality, there is a shift to the importance of major postoperative complications and long-term morbidity regardless of surgical technique. [ABSTRACT FROM AUTHOR]

Video-assisted thoracoscopic surgery (VATS) has gained broad acceptance among pediatric surgeons. Today, VATS can be regarded as a routine approach for various conditions in neonates and infants. However, there is a lack of information concerning the complications of thoracoscopic pulmonary surgery in neonates and infants. We aimed to review the available data. A systematic review of the literature was performed using PubMed. All publications reporting on VATS for pulmonary procedures in neonates and infants up to the age of 1 year were included. Articles were reviewed in detail for occurrence of perioperative complications and their treatment. Nine case series were eligible for analysis. Entities treated included lung sequestration, congenital pulmonary airway malformation, congenital lobar emphysema, and bronchogenic cyst. Case series reported on a total number of 135 patients. Complications occurred in 14 patients (10.4%). The major complication was an accidental transection of the middle lobar bronchus that concluded in a later resection of a prior unaffected lung lobe. Other relevant complications reported were bleeding in four patients (3.0%) and persistent air leak in four cases (3.0%). Infectious complications were reported in four patients (3.0%). Additionally, iatrogenic phrenic nerve paralysis occurred in one patient. There were no deaths related to the VATS technique. In 11 cases (8.1%), conversion to thoracotomy had been necessary. General recommendations on the treatment of complications could not be derived due to small patient numbers and lack of details of the complications reported. Reports on major complications of pulmonary VATS in neonates and infants below 1 year of age are scarce. As severe complications such as accidental bronchus transection have been described, feasibility of neonatal/infant VATS cannot be unequivocally confirmed. No literature-based recommendation can be given on the treatment of complications. [ABSTRACT FROM AUTHOR]

Introduction Laparoscopic techniques have evolved quickly in recent years and are regarded as standard procedures in pediatric surgery today. However, most studies comparing laparoscopic operations with the corresponding open procedure do not reach a high level of evidence according to the criteria of the Oxford Centre for Evidence- Based Medicine. For evidence Level 1a, a meta-analysis (MA) of different randomized controlled trials (RCTs) is required. For evidence Level 1b, at least one RCT is required. The aim of our study was to evaluate the availability of Level 1 studies comparing laparoscopic procedures with the corresponding open operation in pediatric surgery. Materials and Methods Systematic review of clinical Level 1 studies using PubMed. All MA and RCT were identified and individually reviewed. Only studies comparing pediatric laparoscopic procedures with the corresponding open operation were included. RCTs included in MA were only individually analyzed if they focused on additional endpoints. Endpoints of the study were advantages and disadvantages of laparoscopy compared with the open operation. Results A total of 20manuscriptsmet the inclusion criteria (9 MA and 11 RCT). Studies providing evidence Level 1a were identified for five types of laparoscopic procedures (laparoscopic appendectomy, inguinal hernia repair, orchidopexy, pyloromyotomy, and varicocelectomy). Studies providing evidence Level 1b were identified for two types of laparoscopic procedures (fundoplication and pyeloplasty). The advantages of laparoscopy were less wound infections, ileus and postoperative pain (appendectomy), less retching (fundoplication), lower incidence of metachronous inguinal hernia, shorter hospital stay (appendectomy, orchiopexy, and pyeloplasty), and shorter time to full feeds (pyloromyotomy). Conclusion Studies providing evidence Level 1 are only available for seven laparoscopic procedures in pediatric surgery. Effort has to be made to extend the existing Level 1 evidence and to gain high level evidence for further laparoscopic procedures. [ABSTRACT FROM AUTHOR]

Abstract: Background: This study aimed to analyze the feasibility of subsequent minimally invasive pectus repair, particularly modified Nuss procedure, combined with simultaneous thoracic procedures for different underlying intrathoracic diseases and conditions. Methods: A total of 110 patients, who underwent minimally invasive pectus repair in Nuss technique over a 5-year period, were retrospectively analyzed concerning complications, cosmetic results, and satisfaction. Six patients (5%) underwent the Nuss procedure with concomitant thoracic interventions. Patients with prior cardiac surgery or planned redo pectus repair were not examined and were excluded. The mean age of 6 patients (3 male and 3 female) was 11 years (range, 5.5-17.2). Two patients with former left-sided transabdominal diaphragmatic hernia repair and 1 with former lobectomy of the left lower lobe underwent thoracoscopic adhesiolysis. Two underwent thoracotomy: one for closure of a recurrent left-sided diaphragmatic hernia with fundoplication owing to a large hiatal hernia, another for lobectomy of the right middle lobe owing to recurrent infections and bronchodysplasia. One patient presented with anterior mediastinal mass, which was suspected to be benign, and underwent thoracoscopic complete resection. All patients underwent a 1-stage procedure with subsequent simultaneous Nuss procedure. Results: Simultaneous Nuss procedure was feasible without intraoperative complications in all patients (100%). Thoracoscopic adhesiolysis did not affect the feasibility of the Nuss procedure in 3 patients with former diaphragmatic hernia repair, particularly former lobectomy in one. Thoracotomy with middle-lobe lobectomy, as well as repair of recurrent diaphragmatic hernia and fundoplication in 2, did not affect modified Nuss technique and dispensed thoracoscopic guidance. Histopathologic analysis in one patient with a removed anterior mediastinal mass revealed Hodgkin lymphoma (stage IA), and the patient received multiagent chemotherapy. The postoperative course was uneventful in 5 of 6 patients. One patient required intermittent drainage of pleural effusion after simultaneous lobectomy. At follow-up (6 months-5 years), 6 patients had excellent cosmetic results and good quality of life confirmed by a questionnaire. There was no evidence of recurrent malignancy in one patient after 6 months. Conclusions: Thoracic surgery and subsequent Nuss procedure can be performed simultaneously. Underlying conditions, such as prior repair of congenital diaphragmatic hernia or diaphragmatic eventration, as well as former lobectomy, had no impact on feasibility. Open thoracotomy can be combined with Nuss procedure dispensing thoracoscopy. [Copyright &y& Elsevier]

Background: This study was conducted to evaluate the feasibility of using the LigaSure vessel sealing system (Valleylab, Boulder, CO) in laparoscopic transperitoneal vs. open retroperitoneal heminephroureterectomy in children. Materials and Methods: Seven consecutive patients with impaired renal duplex systems underwent laparoscopic heminephroureterectomies using LigaSure between April 2003 and April 2005. The operative time, complications, and hospital stay were analyzed prospectively. The data of 7 consecutive patients who had undergone open retroperitoneal heminephroureterectomy from 2001 to 2003 were analyzed for comparison purposes. The mean ages, underlying disease, and location of the affected kidney pole were not significantly different between these groups. Results: There were no intraoperative complications during laparoscopic heminephroureterectomy and all procedures were completed laparoscopically. The mean operative time of 144 minutes (range, 90–210 minutes) for laparoscopic heminephroureterectomy was somewhat longer than in open heminephroureterectomy-mean time 110 minutes (range, 60–165 minutes) (P = 0.5). Complications of open retroperitoneal heminephroureterectomy included bleeding of the surface of the remaining kidney pole in one patient, requiring extensive hemostatic suturing. Postoperative recovery was uneventful in all laparoscopic procedures, whereas intermittent retention of urine was noticed in one patient undergoing the open procedure. Conclusion: Laparoscopic heminephroureterectomy using LigaSure is feasible in children and has a similar operative time compared to conventional heminephroureterectomy. [ABSTRACT FROM AUTHOR]

Abstract: Background: Minimally invasive repair of pectus excavatum (MIRPE) has become widely popular since its introduction in the late 1990s by Nuss. We describe 1 unusual complication after MIRPE and 1 life-threatening bleeding during removal of the pectus bar. Methods: We report the cases of 2 patients in a single institution, more than 100 MIRPE procedures performed so far, and review of literature. Cases: A 14-year-old girl presented 6 months after MIRPE in another institution. During removal of the pectus bar, a massive hemorrhage from both chest wounds occurred, requiring emergency sternotomy. Arrosion of a pulmonary vessel close to the metal bar had led to the bleeding. The second case was a bilateral sternoclavicular dislocation after MIRPE, which has not caused symptoms so far, in a 13-year-old girl. Conclusions: Numerous operative and postoperative complications after MIRPE are feasible. This is the first report of a life-threatening bleeding during removal of the pectus bar. Minimally invasive repair of pectus excavatum procedure and removal of the pectus bar should only occur in specialized institutions with wide experience in thoracic surgery. [Copyright &y& Elsevier]
