Background: Solid pseudopapillary neoplasm (SPN) of the pancreas in children is a rare tumor with low malignant potential. Some tumors, however, behave aggressively. There is very little literature on managing these variants, especially in children. We share our experience of managing large and recurrent SPN and explore the clinicopathological findings correlating to the risk of recurrence. Methods: This is a retrospective study of children treated for SPN between 2012 and 2022 at a tertiary care center in India. The clinicopathological features and management strategies in these children were evaluated. Results: Sixteen children with SPN were treated during this period (88% of girls). The median age of presentation was 12 years (interquartile range [IQR]: 9-14). All children presented with abdominal pain. Computed tomography gave a definitive diagnosis in 81% of cases. The tumor predominantly involved the head of the pancreas (n = 9, 56%). Eight of nine children classified as high-grade (HG) malignant had a benign course. One child had a recurrence of the tumor 4 years after the initial resection and further recurrence on chemotherapy. She required radiation therapy in addition to reoperation following which she was disease free for 77 months. The overall median follow-up was 46 months (IQR: 18-72 months). Conclusion: Complete resection of the tumor provides a cure in most patients with SPN. Recurrent tumors require a multi-modality approach. Long-term survival is good. There is a need for clear definitions of the components within the WHO criteria for HG malignancy. [ABSTRACT FROM AUTHOR]

Background: Accidental ingestion of foreign bodies in children is critical, as the inability to effectively communicate can potentially lead to devastating consequences. We aimed to determine the epidemiology of foreign body ingestion and variability according to age, gender, type, and location of foreign body, and describe its management. Aim and Objective: The aim was to study the various types of foreign body ingestions in children admitted to pediatric surgery and their management. Materials and Methods: A retrospective study was conducted from January 2020 to June 2022 on children under the age of 12 years with a confirmed diagnosis of foreign body ingestion. Patients were clinically and radiologically assessed, after which standard protocols were followed wherein patients were followed by either observation or emergent management. Emergent management included removal of the foreign body by either endoscopy or surgery. Comparisons among multiple age groups, gender, type of foreign body, location of foreign body, and their management were analyzed. Results: Out of 99 subjects in our study, there were 76 boys and 23 girls. The median age of presentation was 5 years. Most children were asymptomatic at presentation. The most frequently ingested foreign body was a coin in all age groups. The majority of the foreign bodies were suspected to be in the small bowel. The foreign bodies that had crossed the duodenojejunal flexure (n = 74, 74.7%) were managed conservatively with the observation of a variable period of a minimum of 24 h and a maximum of 48 h. 21 cases were managed by endoscopic removal, while three cases required surgical intervention. Conclusions: Overall, the most common gastrointestinal foreign body was a coin in all age groups. Button battery is the most worrisome foreign body; however, depending on its position, it can be managed conservatively. Upper GI foreign bodies can be safely removed endoscopically. Parental counseling is very important for the prevention of ingestion of foreign bodies. [ABSTRACT FROM AUTHOR]

Purpose: The purpose was to study the correlation between age at surgery and functional recovery after infant pyeloplasty. Materials and Methods: All infants who underwent pyeloplasty were analyzed retrospectively in this multicenter study. Anteroposterior diameter (APD) >2 cm, split renal function (SRF) <40%, and Society of Fetal Urology (SFu) grade 3-4 were surgical indications. Based on the age at pyeloplasty, they were divided into Group 1 (1-3 months) and Group 2 (4-12 months). APD and SRF were compared before and after surgery in both groups. The fractional recoverable function (post-SRF-pre-SRF)/(50-pre-SRF) ><100 was correlated with age. Results: Fifty-one infants underwent pyeloplasty (mean age: 1.6 months - Group 1 and 7.2 months - Group 2). The mean APD decreased from 3 cm to 1.2 cm in Group 1 while 2.8 cm to 2 cm in Group 2 (P = 0.001). The mean SRF increased from 32.28% to 42.81% in Group 1 while 31%-34.18% in Group 2. SRF recovery was significantly higher in Group 1 compared to Group 2 (P = 0.001). Regression analysis showed a weak negative correlation (r = -0.2792) between age at surgery and renal function improvement. Conclusion: Functional recovery after pyeloplasty is better when done earlier (1-3 months), as this gives the growing kidney the best opportunity to recover. [ABSTRACT FROM AUTHOR]

Introduction: Malrotation is a congenital anatomical anomaly that affects the normal positioning of the intestines. Traditional management of malrotation, as described by Ladd, consists of detorsion of the volvulus if present, division of Ladd's bands, widening of the mesenteric root, proper positioning of the small and large bowels, and a prophylactic appendectomy. This study was done to determine whether appendectomy should be an integral part of the Ladds procedure or if it can be avoided. Materials and Methods: This retrospective observational study was conducted in one pediatric surgical unit in the tertiary care center of North India. All the cases of malrotation of the gut managed from January 2008 to December 2018 were reviewed. The details of the patients were recovered from the electronic data recording system of the hospital and manual operation theater records. The cases that have a follow-up of <5 years were not included in the study. The details were charted in an Excel Sheet for the analysis. No statistical test was performed because there was no event in patients in whom prophylactic appendectomy was not done. Results: The data analysis revealed that a total of 66 malrotation patients were managed during this period, those who fulfilled the inclusion criteria. Among 66 cases included in the study, in 41 cases, prophylactic appendectomy was done, whereas in the rest 25, prophylactic appendectomy was not done. During the follow-up, none of the patients in whom the appendix was preserved presented with signs or symptoms related to appendicitis or any other complications. Conclusion: Ladds procedure without appendectomy can be performed in view of the potential use of the appendix in the future, and with the fact that in the current era of advanced medicine, appendicitis can be diagnosed early due to the advancement of imaging and better record keeping.

Introduction: Peutz--Jeghers Syndrome (PJS) is an autosomal dominant disease presenting with hamartomatous polyps in the gastrointestinal tract and hyperpigmented macules on lips and oral mucosa. The incidence of this syndrome is approximately 1 in 1,20,000 births. Materials and Methods: In this article, we are presenting 11 cases of PJS which were misdiagnosed and patients were compelled to visit hospital repeatedly. All these cases were diagnosed based on clinical suspicion, family history, and histopathological examination of specimens. Most of the cases presented with intussusception and required emergency surgical management. Results: PJS can be diagnosed by the presence of microscopically confirmed hamartomatous polyps and a minimum of two of the following clinical criteria: Family history, mucocutaneous melanotic spots, and small bowel polyps with bleeding per rectally. The diagnosis can be missed if the melanotic spots on the face are missed. Routine investigations, imaging, and endoscopy were done in all cases. PJS patients need regular follow-up due to chance of recurrence of symptoms and susceptibility to cancer. Conclusion: PJS needs a high index of suspicion for diagnosis in cases of recurrent abdominal pain with bleeding per rectum. Proper family history and meticulous clinical examination for melanosis are very important to prevent the misdiagnosis of these cases. [ABSTRACT FROM AUTHOR]

Aim: The aim of the study was o define the preoperative diagnostic clinical and radiological features in girls with congenital pouch colon (CPC). Materials and Methods: Records of 47 girls with CPC, managed from 1996 to 2018, were reviewed. There were two age groups: Group A (newborn to 12 months; n = 26) and Group B (>12 months to 20 years; n = 21). The important clinical and radiologic features to help in a preoperative diagnosis were noted. Results: The most common subtype was Type II (57.4%), followed by Type I (23.4%) and Type III (12.8%). The features common to both the groups were abdominal distension (A = 53.8%; B = 9.52%), severe perineal excoriation (A = 19.2%; B = 23/8%), and urinary incontinence (A = 30.7%; B = 85.7%). In addition, in Group B, fecaloma on abdominal palpation was noted in 28.6% of patients. The characteristic appearance of the perineum including external genitalia and findings on plain abdominal X-ray (AXR) were 100% accurate and hence diagnostic. These unique features helped us formulate an algorithm for preoperative diagnosis of this uncommon form of anorectal malformation in girls seen in North India. Conclusions: The characteristic features on clinical examination should alert one to the presence of CPC in the outpatient clinic. The AXR was diagnostic in 100% of cases and is mandatory. If any doubt persists, examination of the genitalia under anesthesia with more retraction of the labial folds and endoscopy can be performed for confirmation. These measures should enable a clinician to make an accurate preoperative diagnosis in every girl with CPC. [ABSTRACT FROM AUTHOR]

Background: Benign renal tumors are extremely rare and were studied here. This series also includes a renal teratoma in a horseshoe kidney, probably only the second in the pediatric literature. Materials and Methods: Retrospective review of children with benign renal tumors operated between 2006 and 2018 at one center. Results: Twelve patients (M:F ratio 10:2), age range 3 weeks (31-week gestation) to 13 years presented with large palpable renal swelling (n = 12) and hematuria (n = 3). Computed tomography (CT) scan showed features typical of the tumor. Final histopathology (age group [mean]) showed: multilocular cystic nephroma (MLCN) - n = 5 (41.7%), (11–16 months [13.6]); congenital mesoblastic nephroma (CMN) - n = 4 (33.3%) (classic 1, cellular 3) (0.75–5 months [2.125]); mature cystic teratoma - n = 1 (8.3%): (48 months, in a horseshoe kidney), and angiomyolipoma (AML) - n = 2 (16.7%) (144 months [sporadic] and 156 months [tuberous sclerosis]) One patient with cystic teratoma with no calcification on CT scan received pre-operative chemotherapy as fine-needle aspiration cytology (FNAC) reported malignant small blue cell tumor. Nephroureterectomy with Gerota's fascia could be done easily in all without intraoperative complications. Delay in presentation in MLCN and CMN led to increased symptoms and CT scan changes. All patients did well in 1.5–12 years (median 3 years) follow-up including cellular mesoblastic nephroma. Conclusions: Benign renal tumors often occur in specific age groups but may overlap that of Wilms tumor. Proper interpretation of clinical presentation, CT scan, and FNAC findings help in avoiding preoperative chemotherapy. Upfront nephroureterectomy is curative. Histopathological findings decide further treatment. Children with AML and tuberous sclerosis need lifelong follow-up. [ABSTRACT FROM AUTHOR]

Objectives: The aim of this study was to review the clinical profile, management, and outcome of solid tumors in the head-and-neck region in children at our institute. Methods: We retrospectively reviewed children with head-and-neck solid tumors who were treated jointly under the departments of Pediatric Surgery and Otorhinolaryngology at our institute between 2016 and 2019. Results: In the study period, 10 children (6 males, 4 females) with a median age of 9.5 years (range 5 days–16 years) were treated by our unit. The patients had four tumors arising from the parotid, 2 from nose/naso-pharynx, 1 each from the tongue, submandibular gland, para-pharyngeal space, and infratemporal fossa. A majority (90%) of the patients underwent complete surgical excision of the tumor, preserving the loco-regional neurovascular structures to minimize postoperative morbidity. Malignant lesions were seen in 4 patients (2 rhabdomyosarcoma, 1 primitive neuro-ectodermal tumor, 1 mucoepidermoid carcinoma) and 6 patients had benign pathology (3 pleomorphic adenoma, 2 mature teratoma, 1 schwanomma). Additional therapy with chemotherapy and local radiotherapy was required in 3 out of 4 patients with malignant pathology. The median follow-up duration is 15 months. At last follow-up, all patients are alive and 9 out of 10 patients (90%) are disease-free. Conclusion: Our experience highlights rare and difficult tumors in the head-and-neck region in children. These tumors are not commonly managed by the pediatric surgeon in routine practice. The paper outlines the multi-modality management of these tumors, which is essential for an optimal outcome.

Context: Adnexal masses in girls represent a wide pathological spectrum. We performed a retrospective analysis of clinical and diagnostic aspects of adnexal masses in girls. Aims: To analyze the clinical characteristics and surgical management of adnexal masses in children and adolescents. Settings and Design: Retrospective observational analysis from 2000 to 2020. Subjects and Methods: This analysis was performed on 28 children under the age of 17 years with adnexal masses who were managed by us at tertiary care centers of Delhi-NCR. Patients were analyzed based on their age at the time of admission, their presenting complaints, clinical and radiological findings, tumor markers, management, and follow-up. Results: The age ranged between newborn and 17 years. Abdominal pain, nausea with vomiting, and abdominal lump was the most common presenting complaints. Pelvic ultrasound with or without color Doppler done in all patients and computed tomography, magnetic resonance imaging was performed in seven patients preoperatively. Adnexal masses were unilateral in 26 (92.85%) patients and bilateral in 2 (7.15%) patients. Five babies had antenatal diagnosis of ovarian cysts. Serum alpha fetoprotein (AFP) and beta-human chorionic gonadotropin (b-HCG) were normal in all 19 tested patients. Cancer antigen 125 (CA-125) was raised in three ovarian tumors out of 9 tested patients. Laparoscopy was performed in 23 out of 28 patients (30 ovaries). Ovarian cyst torsion was present in 50% patients. Ovarian cystectomy was done in 10 (33.3%) patients. Six (20%) ovaries were saved by detorsion of the ovary and deroofing of the cyst with or without ovarian biopsy. Oophorectomy was done in five (16.7%) patients. Salpingo-oopherectomy had to be done in seven (23.3%) patients. Histopathology revealed functional nonneoplastic lesions in 18 cases (66.7%), benign neoplastic lesions in 8 cases (29.6%), and malignant neoplastic lesion in 1 case (3.7%). Conclusions: Adnexal masses in children are generally benign. AFP, b-HCG, and CA-125 in ovarian torsion are within normal limits. Urgent surgery is required if torsion is established. The ovary should be preserved wherever possible. [ABSTRACT FROM AUTHOR]
