Laparoscopic histological mapping for the determination of the length of aganglionic segment in children with Hirschsprung disease.

BACKGROUND: Modern approach to the surgical treatment of Hirschsprung's disease (HD) consists in the earliest possible repair and reduction of the number of surgical interventions. Primary one-stage transanal endorectal pull-through (TEPT) technique requires preoperative determination of the length of aganglionic segment. The efficacy of the standard method - contrast enema - is questionable in patients with a poorly defined transitional zone. OBJECTIVES: To present the proposed laparoscopic method for the management pathway in patients with HD, in whom the determination of the length of aganglionic segment with contrast enema was not possible. MATERIAL AND METHODS: A retrospective analysis of the diagnostic and therapeutic management employed in 14 patients, from 2 weeks to 55 months of age, with diagnosed HD, treated between January 2013 and May 2020. Laparoscopic histological mapping was performed with the use of 3 laparoscopic ports of 3-5 mm diameter. RESULTS: In all patients, laparoscopic mapping allowed for the determination of the length of aganglionic segment and the mode of surgical treatment. Four children with determined short-segment disease underwent TEPT, while 2 underwent temporary colostomy formation using the Duhamel-Martin-Ikeda method. Five patients with long-segment HD underwent laparoscopic-assisted TEPT. One patient with long-segment disease was treated with a temporary double-barrel colostomy and definitive surgery was performed 3 months later using the Duhamel-Martin-Ikeda method. In 2 patients with an initial diagnosis of HD established using current diagnostic pathway, HD pathology was later excluded based on the results of laparoscopic mapping and repeat rectal suction biopsy. No complications related to the laparoscopic procedure were identified. CONCLUSIONS: The method of laparoscopic mapping is effective in the determination of the length of aganglionic segment in children with diagnosed HD. In doubtful cases, it can be the preferred option in establishing the final mode of surgical treatment.

Ovarian Sparing Surgery in Mature Ovarian Teratomas in Children: A 20-Year Single-Center Experience.

INTRODUCTION: Despite its benign nature, possible bilateral presentation, and a very good prognosis, ovarian sparing tumorectomy (OST) in mature ovarian teratoma (MOT) is not commonly performed. Unilateral oophorectomy has physiological consequences, while bilateral is devastating. The aim of this study is promotion of OST in MOT among children. MATERIALS AND METHODS: We reviewed 120 patients operated for MOT between August 1999 and 2019. RESULTS: Ovariectomy was performed in 15 patients (14 between 1999 and 2009 and 1 after 2010). In 105 girls, OST was possible including 32 with ovarian torsion. The approach was laparoscopy in 30 girls (11 conversions) and laparotomy in 94. Intra-abdominal spillage occurred in 30% of laparoscopic dissections. Postoperative morbidity was not associated with surgical approach (p = 0.613) or presence of adnexal torsion (p = 0,608). Follow-up was from 4 months to 9 years (median = 4 years) with access to 90% of patients. Bilateral lesions were observed in six (synchronous in five and metachronous in one) patients. Recurrence appeared in three patients operated via laparotomy and OST (after 12, 46, and 74 months). In one girl, asynchronous contralateral MOT was found 5 years after unilateral oophorectomy. Ovarian regeneration after torsion was observed in sonography in 84.4% of the patients. None of the patients experienced chemical peritonitis or malignant tumor transformation. CONCLUSION: OST is safe and effective and should be the first-line procedure in children. Laparoscopy and laparotomy constitute a complementary approach to MOT. Ultrasound follow-up is necessary to monitor recurrence, contralateral disease, and ovarian regeneration.

The application of the percutaneous suturing technique in thoracoscopic repair of congenital diaphragmatic hernia.

BACKGROUND: Thoracoscopic surgery of congenital diaphragmatic hernia (CDH) is connected with a higher incidence of recurrence than open repair is. This is usually caused by the dehiscence of sutures in the lateral part of the defect. This area is characterized by increased tension on proximate tissues and difficult thoracoscopic suturing. For more effective repair, the authors adopted a variant of percutaneous internal ring suturing (PIRS) technique. OBJECTIVES: To present and evaluate the efficacy of the PIRS technique for the repair of CDH. MATERIAL AND METHODS: The study is based on retrospective analysis of the medical data of patients with CDH treated in the Department of Pediatric Surgery of the Jagiellonian University Medical College (Kraków, Poland) from January 2013 to July 2019. The PIRS technique was applied when thoracoscopic repair under acceptable tension appeared impossible. RESULTS: Fifty-one patients were identified. Of these, 11 children died before surgery and 1 after, leaving 39 (76%) who were operated on and survived. Thoracoscopy was used in 27 cases (69%), with 3 conversions. The recurrence rate in patients who underwent thoracoscopic closure of the defect with intermittent sutures was 27% (3 out of 11 children), while in the group that underwent thoracoscopic repair with the additional use of percutaneous suturing, the recurrence rate was 6.25% (1 out of 16 patients). The follow-up periods ranged from 4 months to 6 years. CONCLUSIONS: The applied PIRS technique permits safe and effective closure of intermediate-size diaphragmatic defects under acceptable tension. The method is feasible and can be listed among countermeasures against recurrence.

Staged Thoracoscopic Repair of Long-Gap Esophageal Atresia Without Temporary Gastrostomy.

Introduction: Primary repair of long-gap esophageal atresia (LGEA) continues to present a surgical challenge. The number of treatment options, including the use of native esophagus or esophageal replacement, shows the difficulty in the treatment and lack of one superior option. Until recently all children with LGEA required temporary gastrostomy before esophageal reconstruction. Objective: The aim of the study is to present new therapeutic management in patients with LGEA, involving staged thoracoscopic procedure with internal traction without gastrostomy. Materials and Methods: Four neonates with LGEA were treated in two academic Departments of Pediatric Surgery in Poland from 2015 to 2018. The intervention was staged thoracoscopic approach, consisting in internal traction, followed by delayed esophageal anastomosis in neonatal period. The outcome measures were successful anastomosis, short time anastomosis complications, and timing of gastric/oral feeding. Results: Internal traction was placed between 2 and 6 days of life. A successful repair of native esophagus by the second approach in neonatal period without gastrostomy was achieved in 3 out of 4 neonates, 5-8 days after internal traction placement. No anastomotic leakage was observed, two anastomoses developed stricture managed with three and four sessions of repeated dilatation. Nasogastric tube feeding started between 5 and 7 days with full oral feeding achieved between 10 and 35 days after anastomosis. Follow-up was after 1-34 months. Conclusions: Our technique should be considered an alternative first-line strategy for the repair of LGEA without the use of a gastrostomy.

Cosmetic Outcomes of Sutureless Closure in Gastroschisis.

Purpose A sutureless gastroschisis repair allows for spontaneous closure of abdominal wall defect. We report our experience focusing on final esthetic outcome. Methods Retrospective data were collected from medical reports of all neonates with gastroschisis operated from January 2009 to December 2013. Variables recorded included patients descriptors, management modality, and cosmetic outcome. Results From the overall group of 38 patients with gastroschisis, 20 infants treated with sutureless closure were included in this study. In the analyzed cohort, 17 (85%) children were operated under general anesthesia and 3 (15%) without intubation. Primary reduction was possible in 15 (75%) cases, and in 5 (25%) we used silo. There were two (10%) deaths in late postoperative course due to septic complications. Three (15%) infants needed laparotomy because of adhesions and bowel obstruction. There were no infectious complications of the wound. Only 55% (10/18) of children presented umbilical hernia prior to discharge. Only two (11%) children with umbilical hernia were operated until now. Almost all patients (16/18; 89%) present excellent final cosmetic result without scar formation. Conclusion Sutureless closure of uncomplicated gastroschisis is a safe technique that reduces need of intubation and provides excellent cosmetic results.

Laparoscopic and Laparoscopy-Assisted Resection of Enteric Duplication Cysts in Children.

INTRODUCTION: Enteric duplication (ED) cysts are rare. The commonness of ultrasonographic investigation contributes to an earlier diagnosis of such a pathology before the onset of the first clinical symptoms. A planned mini-invasive surgical treatment during the infancy is proposed. This study presents the possibility and safety of elective laparoscopic or laparoscopy-assisted mini-invasive resection of ileal (IL) and ileocecal (IC) duplications, thus avoiding bowel resection. MATERIALS AND METHODS: A retrospective review was conducted of medical records of 6 patients at the age from 3 to 22 months with the diagnosis of ED, treated in the Department of Pediatric Surgery, Jagiellonian University Medical College, Krakow, Poland, within the period from January 2012 to September 2014. RESULTS: Excision of cysts without bowel resection was performed in five children with IC and IL duplications. Laparoscopic excision was performed in two children with IC duplication; in the other three children (1 IC and 2 IL duplication), laparoscopy confirmed the diagnosis with consecutive cyst excision without bowel resection after external evacuation of the cyst. The external resection of the cecum and Bauhin's valve was necessary in 1 patient with large IC duplication and malrotation. The postoperative course was satisfactory in all the cases. CONCLUSIONS: The laparoscopic approach allows for confirming the diagnosis and accurately defining the exact site of duplication, as well as for effective and safe mini-invasive treatment. Laparoscopic or laparoscopy-assisted excision of ED without bowel resection is a safe option in a significant number of IL and IC duplications.
