Percutaneous Tracheostomy Via Grigg's Technique in Children: Does Age and Size Matter?

OBJECTIVES: Percutaneous tracheostomy is rarely performed in children, especially in infants. In the present study, we aimed to evaluate the complications and outcomes of PT via the Griggs technique according to the age and size of pediatric patients. METHODS: This study included 110 PICU patients who underwent PT using the Griggs technique between 2012 and 2020. The patients were divided into six groups according to their age, demographic data, primary disease, mean duration of intubation before PT, mean duration of PICU and hospitalization after PT, complications, and decannulation outcomes were compared between these groups. RESULTS: The mean age and mean weight of the patients were 43.6 ± 58.9 months (1 month-207 months) and 14.6 ± 14.9 kg (2.6-65 kg), respectively. Mean intubation times before the procedures were 64.6 ± 40 days and 38.6 ± 37.9. Thirty-seven (33.6%) infants were under 6 months of age(Group 1). There were no intraoperative complications. Tracheostomy site stenosis was significantly greater in Group 1 than in the other age groups (p = 0.032). Granuloma formation and dermatitis incidence were similar in all age groups. CONCLUSION: PT is a safe and feasible procedure even in small infants. The accidental decannulation risk is lower than standard tracheostomy. Interacting with rigid bronchoscopy guidance is essential to perform a safer procedure. The first tracheostomy change after PT in small infants under 6 months of age, the possibility of tracheostomy site (stoma) stenosis should be considered. LEVEL OF EVIDENCE: Level III Laryngoscope, 2024.

Neurodevelopmental evaluation of children who were operated due to congenital anomaly with the 'Ages and Stages Questionnaire (ASQ)' and 'ASQ: Social-Emotional'.

BACKGROUND: The purpose of surgeries performed for congenital anomalies in children is to increase the survival rates and provide a developmental comparison to that of their peers. AIM: The objective of this study was to investigate the development of children following surgery for congenital anomalies and the risk factors affecting their development. METHODS: Our study included 33 children who underwent surgery for gastrointestinal anomalies in our clinic between 2011 and 2016, and did not have any syndrome, chromosomal abnormality, or additional abnormality. Developmental levels were evaluated using the Ages and Stages Questionnaire (ASQ) and the ASQ: Social-Emotional (ASQ: SE) scales adapted for the use on Turkish children. Data on patient history were obtained retrospectively from patient files. RESULTS: The study included 33 patients, including 11 with esophageal atresia, 6 with intestinal atresia, 11 with anorectal malformation, and 5 with Hirschsprung's disease. Developmental delay was found in the ASQ of 72.7% of the patients and the ASQ: SE tool was 27% of the patients. The rate of patients with scores below the threshold from each parameter of ASQ was higher than that of the normal population (p < 0.05). Development delay was detected using the ASQ scale in 100% of those with microcephaly at birth, in 91% of premature infants born between 1500 and 2500 g, and in 83.3% of those with low birth weight to gestational age. CONCLUSIONS: In children who underwent surgery due to congenital anomalies, an evaluation through developmental tests, a post-surgical follow-up process, and a referral to the relevant disciplines when necessary may increase the success of surgery as well as increase the life quality of the patient.

Comparison of the results of open repair and laparoscopic repair with the PIRS method in the treatment of hydrocele in children.

PURPOSE: Hydrocele is a result of intraperitoneal fluid filling into the scrotum through the patent processus vaginalis (PPV). While the traditional approach of pediatric hydrocele has been open repair (OR) for years, laparoscopic repair (LR) of hydrocele has been accepted worldwide after the proven efficacy of laparoscopy. The purpose is to compare the outcomes of both techniques in a single center. METHODS: We retrospectively analyzed the clinical data of all the patients who underwent hydrocele repair from August 2016 to November 2022. In our center, the standard approach was OR in hydrocele until the November of 2021. Starting from this date, LR has begun to be preferred, as the experience has increased and its success has been observed. In the LR group, single-port percutaneous internal ring suturing technique was performed. RESULTS: The data of 113 patients (OR 58.4% (n = 66), LR 41.6% (n = 47)) were collected. In preoperative examination, 12.4% (n = 14) patients were diagnosed as communicating and 87.6% (n = 99) non-communicating hydrocele. Intraoperatively, 65.5% (n = 74) patients were communicating and 34.5% (n = 39) were non-communicating. Total recurrence rate was 7% (n = 8). The OR group experienced a recurrence rate of 10.6% (n = 7), while the LR group experienced 2.12% (n = 1). CONCLUSION: Laparoscopy may reveal intrabdominal connection of hydrocele better than open approach. It provides a high quality view of both inguinal rings and has the advantages of minimally invasive surgery.

Early Postoperative Serum Phosphate Drop Predicts Sufficient Hypertrophy After Liver Surgery.

OBJECTIVE: The aim of this study was to assess the impact of postoperative hypophosphatemia on liver regeneration after major liver surgery in the scenario of Associating Liver Partition with Portal vein ligation for Staged hepatectomy (ALPPS) and living liver donation (LLD). BACKGROUND: Hypophosphatemia has been described to reflect the metabolic demands of regenerating hepatocytes. Both ALPPS and LLD are characterized by an exceptionally strong liver regeneration and may be of particular interest in the context of posthepatectomy hypophosphatemia. METHODS: Serum phosphate changes within the first 7 postoperative days after ALPPS (n=61) and LLD (n=54) were prospectively assessed and correlated with standardized volumetry after 1 week. In a translational approach, postoperative phosphate changes were investigated in mice and in vitro . RESULTS: After ALPPS stage 1 and LLD, serum phosphate levels significantly dropped from a preoperative median of 1.08 mmol/L [interquartile range (IQR) 0.92-1.23] and 1.07 mmol/L (IQR 0.91-1.21) to a postoperative median nadir of 0.68 and 0.52 mmol/L, respectively. A pronounced phosphate drop correlated well with increased liver hypertrophy ( P <0.001). Patients with a low drop of phosphate showed a higher incidence of posthepatectomy liver failure after ALPPS (7% vs 31%, P =0.041). Like in humans, phosphate drop correlated significantly with degree of hypertrophy in murine ALPPS and hepatectomy models ( P <0.001). Blocking phosphate transporter (Slc20a1) inhibited cellular phosphate uptake and hepatocyte proliferation in vitro. CONCLUSION: Phosphate drop after hepatectomy is a direct surrogate marker for liver hypertrophy. Perioperative implementation of serum phosphate analysis has the potential to detect patients with insufficient regenerative capacity at an early stage.

Early period intensive care follow-up after liver transplantation in children: a single center experience.

BACKGROUND: Liver transplantation (LT) is a well-established, life-saving treatment for children with irreversible acute and chronic liver failure (LF). We aimed to evaluate the factors associated with morbidity and mortality in the early period of LT in children by reviewing our pediatric intensive care unit (PICU) experience. METHODS: We reviewed children`s medical records followed in the PICU after LT between May 2015-August 2021, including demographic parameters, indications for LT, operative variables, respiratory and circulatory support requirements, LT-related complications and survival. RESULTS: During this period, 40 pediatric patients who underwent LT were evaluated. LT was performed in 35 (87.5%) cases of chronic liver disease and 5 (12.5%) cases of acute liver failure. Twenty-four patients had chronic liver failure due to cholestatic liver disease. The patients` Pediatric Risk of Mortality (PRISM) III score was 18.82±SD (2-58) at PICU admission. 1-year survival was 87.5%, and overall survival was 85%. Younger age, low body weight, preoperative pediatric end-stage liver disease (PELD), and model for end-stage liver disease (MELD) values of 20 and higher were important risk factors for unfavorable outcomes after living donor liver transplantation (LDLT). These risk factors are both associated with technically more challenging vascular and bile duct reconstruction and higher complication rates, and increased mortality during the early period after LT. CONCLUSIONS: The early period of optimum PICU management in pediatric LT recipients is crucial for successful outcomes, which is also related to the patients` characteristics, disease severity scores, and surgical procedures.

Management of Biliary Complications in Liver Transplant Recipients with Duct-To-Duct Anastomosis: A Single-Center Experience.

BACKGROUND: The aims of this study were to investigate biliary complications in liver transplant recipients with choledochocholedocho stomy anastomosis, to identify the risk factors for the development of such complications, and to evaluate the success of endoscopic approaches in liver transplant recipients. METHODS: Between January 2013 and May 2021, a total of 238 patients with liver diseases underwent liver transplantation: 174 recipients undergoing choledochocholedochostomy anastomosis were included in the analysis. RESULTS: Their median age was 54.0 years. The median posttransplant follow-up period was 29 months. Hepatitis B virus infection (33%) was the most common indication for liver transplantation. Most patients (87%) received living donor liver transplantation. The overall prevalence of posttransplant biliary complications was 31%. Anastomotic biliary strictures were the most common biliary complications (72%), followed by biliary leakage (13%). The median time between endoscopic retrograde cholangiography and liver transplantation was 4 months, with a mean of 3 ± 1.6 sessions. Endoscopic retrograde cholangiography-guided drainage and balloon dilation with or without stent placement was the most common treatment modalities for recipients with biliary strictures. The overall success rate of endoscopic treatment modalities was 83.3%, with 65% of the recipients exhibiting complete biochemical and endoscopic responses. The response did not differ significantly between living donor liver transplantation and cadaveric donor liver transplant recipients (P > .05). Three recipients required revision surgery for biliary complication repair. Six patients died due to biliary sepsis. CONCLUSION: Biliary stricture and leakages were the most common biliary complications after liver transplantation. Endoscopic treatment was successful in most recipients.

Diagnostic Dilemma of Lactic Acidosis in an Infant After Liver Transplant: A Case Report.

Thiamine is the cofactor of many enzymes involved in energy metabolism. Patients under total parenteral nutrition are at risk for thiamine deficiency if there is renal thiamine loss or increased thiamine requirements to mitigate systemic diseases. Thiamine deficiency symptoms include seizures, neuropathy, ataxia, peripheral vasodilation, myocardial insufficiency, sudden collapse, and death. In this report, we present an infant liver transplant recipient with progressive lactic acidosis that responded well to thiamine replacement to mitigate a lack of thiamine in total parenteral nutrition.

Outcomes of Surgical Strategies for Living Donor Liver Transplantation in Patients With Portal Vein Thrombosis: A Cohort Study.

BACKGROUND: Adequate portal flow to the liver graft is the requirement of a successful liver transplant (LT). Historically, portal vein thrombosis (PVT) was a contraindication for LT, especially for living donor LT (LDLT), demanding technically more difficult operations and advanced technique. In this study, the outcomes of patients with and without PVT after LDLT were compared. METHODS: Adult LDLTs performed by 2 centers (n = 335) between 2013 and 2020 were included into this large cohort study. PVT was classified based on Yerdel classification grade 1 to 4. RESULTS: Sixty-two patients with PVT constituted 19% of the study cohort of 335 recipients. While mean platelet count was found to be lower (P = .011) in the PVT group, patient age (P = .035), operation duration (P = .001), and amount of intraoperative blood transfusion (P = .010) were found to be higher. Incidence of PVT was higher in female patients than males (22.7% vs 16.1%, P = .037). There was no significant difference in survival between patients with and without PVT on 30-day (P = .285), 90-day (P = .565), 1-year (P = .777), and overall survival (P = .917). Early thrombosis did not show a better survival rate than Grades 2, 3, or 4 PVT. Thrombosis limited to portal vein was not found to bring a survival advantage compared with Grade 3 and 4 thromboses. Eversion thrombectomy was the most common procedure (66%) to overcome PVT intraoperatively. CONCLUSION: Although technically more challenging, PVT is not a contraindication of LDLT. Similar outcomes can be achieved in LDLT in patients with PVT after proper restoration of portal flow, which eliminates the default survival disadvantage of patients with PVT.

Living liver donor hilar anatomical variations and impact of variant anatomy on transplant outcomes.

Donor anatomy is an essential part of donor selection and operative planning in living donor liver transplantation. In this study, variations of hilar structures, and the effects of variant anatomy on donor and recipient outcomes were evaluated. Living donor liver transplantations in a single center between January 2013 and December 2020 were retrospectively reviewed. In total, 203 liver transplantations were analyzed. Type 1 arterial anatomy, type 1 portal vein anatomy and type 1 bile duct anatomy were observed in 144 (70.9%), 173 (85.2%), and 129 (63.5%) donors, respectively. Variant biliary anatomy was observed more frequent in donors with variant portal vein branching than in those with type 1 portal anatomy (60.0% vs 32.3%, P = .004). The overall survival rates calculated for each hilar structure were similar between recipients receiving grafts with type 1 anatomy and those receiving grafts with variant anatomy. When donors with variant anatomy and donors with type 1 anatomy were compared in terms of hilar structure, no significant difference was observed in the frequency of complications and the frequency of serious complications. Biliary variations are more common in individuals with variant portal vein anatomy. Donor anatomic variations are not risk factors for inferior results of recipient survival or donor morbidity.

LOCAL-IGF-1 and GH application IMPROVES germ cell histology, spermatogenesis and fertility after experimental testicular torsion and detorsion.

OBJECTIVE: To evaluate the impact of insulin like growth factor-1(IGF-1) and growth hormone (GH) on testis histology, spermatogenesis, and fertility in prepubertal rats exposed to 6 h of testicular torsion (TT) and detorsion. MATERIAL-METHOD: Forty-eight male Wistar-albino rats weighing 30-70g and at 3-week age were allocated into six groups involving eight rats in each group as follows: Group 1:Sham, Group 2:Control, Group 3:Gelatin, Group 4:Local-IGF-1, 5: Local-GH, Group 6: Systemic-GH. Right testis was only exposed and sutured in the sham group, and right testes were rotated clockwise, 720°, fixed, and 6 h later, detorsion on the testis was done in groups 2-6. Unloaded gelatin, 5 µg local-IGF-1 loaded, and 2IU rhGH loaded gelatin were sutured to the right testis after detorsion in groups 3-5. In Group 6, 0.3IU/100gr/d rhGH was given for seven days via subcuticular route after detorsion. Each of the rats cohabited with two female rats five weeks later. Afterward, both right and left testes were removed. Mean diameter of seminiferous tubules (STD), mean biopsy score count of the testis (TBSC), mean percentage of haploid cells (HCP) were assessed, and fertility parameters were evaluated. RESULTS: STD and TBSC of the ipsilateral testes were significantly reduced in control and gelatin groups when compared to sham, local-IGF-1, and local-GH groups. STD and TBSC of the ipsilateral testes of the systemic-GH group were decreased compared to the sham group. HCP of the ipsilateral testes of control, gelatin, and systemic-GH groups were significantly lower than the sham, local-IGF-1, and local-GH groups. STD, TBSC, and HCP of the contralateral testes were significantly reduced in control and gelatin groups when compared separately to sham, local-IGF-1, systemic- GH, and local-GH groups. The difference between groups regarding potency, fertility, fecundity indexes, and mean fetus numbers were not significant. CONCLUSION: Even though there was significant and permanent histologic germ cell damage and reduced HCP in both ipsilateral and contralateral testes, experimental 6 h TT and detorsion in prepubertal rats did not have a negative impact on future fertility. Local-IGF-1and rhGH treatment improved germ cell histology and spermatogenesis in both ipsilateral and contralateral testes of prepubertal rats, subjected to 6 h of TT and detorsion.

Effects of intraperitoneal bupivacaine injection in laparoscopic appendectomy in children on post-operative pain: A controlled randomized double-blinded study.

BACKGROUND: The aim of this study is to determine the effects of local anesthetics administered intraperitoneally in laparoscopic appendectomy. METHODS: Patients who underwent laparoscopic appendectomy due to acute appendicitis were enrolled in the study. The children were divided into two groups. Intraperitoneal bupivacaine injection to appendectomy site and subdiaphragmatic area was performed after resection of appendix and aspirastion of intraperitoneal reactive fluid in Group 1 while Group 2 did not receive this therapy. The children were questioned by a nurse at postoperative 1st, 6th, 12th, and 24th h. Pain scores (PS) (abdominal), abdominal wall incisional pain (IP), shoulder pain (SP), and first need for analgesics were recorded. RESULTS: One hundred and twenty children were enrolled to the study. There was no significant difference in PS values and IP values between the two groups (p>0.05). SP values at 12th and 24th h were significantly lower in Group 1 (p<0.05). There was a statistically significant reduce in analgesic need in Group 1 (p=0.007). CONCLUSION: Intraperitoneal bupivacaine instillation to surgery site and subdiaphragmatic area seems to reduce the SP post-opera-tive and also reduce post-operative analgesic need. More meaningful results can be obtained with an increase in the number of patients.

Hypospadias and the Use of the Ages and Stages Questionnaire to Evaluate Neurodevelopmental Status of Boys with Hypospadias.

INTRODUCTION: Placental insufficiency is one of the reasons for the reduction of hormone production. Thus, if one of the suspected causes of hypospadias is placental insufficiency, then the neurodevelopmental status of boys with hypospadias may be impaired. The aim of this study was to evaluate the neurodevelopmental status of boys with hypospadias and guide the parents of those who need support to related departments for early intervention. MATERIALS AND METHODS: Boys were divided into two groups, those with hypospadias (group H) and healthy children undergoing traditional circumcision (group C). The parents of the boys completed the Ages and Stages Questionnaire (ASQ) and ASQ-Social Emotional (SE), both of which are screening instruments for the early identification of developmental and social-emotional problems, respectively. RESULTS: Seventy-eight boys had hypospadias and 59 were admitted for traditional circumcision. The group H had statistically significant more impaired scores than group C in communication, gross motor, and personal-social skill sections. The multivariate logistic regression analysis revealed that hypospadias was the independent predictive factor for communication and personal-social skills. CONCLUSION: Hypospadias and neurologic impairment may share common etiologic factors. Accordingly, physicians should keep in mind that if a boy presents with hypospadias, the possibility of having neurologic impairment is higher than normal population and early intervention has crucial importance. Every boy with hypospadias should be evaluated for neurodevelopmental status.

Temporary Diverting End-Colostomy in Critically Ill Children with Severe Perianal Wound Infection.

ABSTRACT: Broad and deep perianal wounds are challenging in both adult and pediatric ICUs. These wounds, if contaminated with gastrointestinal flora, can cause invasive sepsis and death, and recovery can be prolonged. Controlling the source of infection without diverting stool from the perianal region is complicated. The option of protective colostomy is not well-known among pediatric critical care specialists, but it can help patients survive extremely complicated critical care management. These authors present three critically ill children who required temporary protective colostomy for perianal wounds because of various clinical conditions. Two patients were treated for meningococcemia, and the other had a total artificial heart implantation for dilated cardiomyopathy. There was extensive and profound tissue loss in the perianal region in the patients with meningococcemia, and the patient with cardiomyopathy had a large pressure injury. Timely, transient, protective colostomy was beneficial in these cases and facilitated the recovery of the perianal wounds. Temporary diverting colostomy should be considered as early as possible to prevent fecal transmission and accelerate perianal wound healing in children unresponsive to local debridement and critical care.

3D-reconstruction and heterotopic implantation of reduced size monosegment or left lateral segment grafts in small infants: A new technique in pediatric living donor liver transplantation to overcome large-for-size syndrome.

BACKGROUND: Monosegmental grafts and reduced left lateral segment grafts have been introduced to overcome the problems of large-for-size grafts in pediatric living donor liver transplantation. Here, we introduce a new method of reduced size monosegment or left lateral segment grafts transplanted in the right diaphragmatic fossa heterotopically in small infants. METHODS: There were 4 infants who underwent living donor liver transplantation with heterotopically implanted reduced monosegmental or left lateral segment grafts at our center. The demographic, operative, postoperative, and follow-up data of these infants were collected from our prospectively designed database and reviewed. Technical details of the donor and recipient operation are shared and a supplemental provided. RESULTS: The mean recipient age was 7.5 ± 0.9 months (range: 5-10 months), and body weight was 5.9 ± 0.7 kg (range: 4.6-7.8). Primary diagnoses of the recipients were biliary atresia (n:3) and progressive familial intrahepatic cholestasis (n:1). Mean graft-recipient weight ratio was 3.3 ± 0.2. Reduced monosegment III grafts were used in 2 cases, and reduced left lateral segment grafts were used in the other 2 patients. Bile duct reconstruction was done by Roux-en-Y hepaticojejunostomy in 3 patients and duct-to-duct anastomosis in the remaining patient. All patients recovered from the liver transplantation operation and are doing well at a mean follow-up of 8 months. CONCLUSION: Living donor liver transplantation with heterotopically implanted reduced monosegmental or left lateral segment seems feasible for the treatment of neonates and extremely small infants. Further accumulation of cases and long-term follow-up are necessary to collect data for the establishment of this treatment modality.

An indirect effect of COVID-19 pandemic: Increased pediatric perforated appendicitis rate due to delayed admission.

Objectives: Appendicitis is a common surgical emergency among children. The coronavirus pandemic affected the system of hospitals more than any other field, and great amount of people were concerned about visiting the hospitals for any reason. In this study, it was aimed to evaluate the profile of appendicitis by emphasizing perforated and acute appendicitis in the pandemic period and to compare the rates with previous three years. Material and Methods: Charts of the children who underwent laparoscopic appendectomy due to appendicitis between March 11-September 30 between 2017-2020 were retrospectively analyzed in terms of demographic data, duration of symptoms, duration between hospital admission and surgery, radiologic imaging and perioperative outcomes. Results: This study includes 467 children who underwent laparoscopic appendectomy. There were 97 procedures in 2020, 111 in 2019, 146 in 2018 and 113 in 2017. Multiple comparison tests revealed that age did not show difference; but onset of symptoms in admission (p= 0.004), hospitalization time before surgery (p <0.001), total hospitalization time (p <0.001) showed statistically significant difference between years. Pairwise comparisons showed that these parameters were increased in 2020 compared to other years. Perforated appendicitis rate was significantly increased in 2020 when compared to previous years. Conclusion: Although there is no direct relation between appendicitis and COVID-19 infection in the current knowledge, perforated appendicitis was found to be increased in children during the COVID pandemic. Reason of the higher rate of perforated appendicitis may be multifactorial; however, the pandemic appears to have a role in increased morbidity in children with appendicitis indirectly due to delay of hospital admissions.

An algorithm for retrieval tools in foreign body ingestion and food impaction in children.

The aim of this study is to review the experience on managing foreign body ingestion in children with special emphasis on the endoscopic techniques and specific retrieval devices used for foreign body (FB) extraction. The charts of 341 children were reviewed retrospectively. Demographic data, ingested material, removal technique and tool, level of FB, complications, and outcomes were recorded. A total of 364 FBs were removed from 341 children. Among these, 56.5% (n: 206) were entrapped in esophagus, 39% (n: 142) were in stomach, and 4.5% (n: 16) in duodenum and intestine. The most frequently ingested items were coin (42.5%), button batteries (20.6%), and safety pins (12%). Optical forceps (37.9%) were the most commonly used tool and they were used during retrieval of esophageal FB by rigid endoscopy. Retrieval net (20.7%) was the second most common tool and the most common one during flexible endoscopy. Depending on our experience, we strongly advocate rigid endoscopy for esophageal FBs and food impaction in children because it allows both to use optical forceps with a strong grasping ability for blunt FBs and to position sharp and pointed objects inside the rigid endoscope. We recommend retrieval net as the first tool for the extraction of blunt objects and rat tooth retrieval forceps is the best tool for sharp and pointed FBs in stomach.
