Implementation and outcomes of enhanced recovery protocols in pediatric surgery: a systematic review and meta-analysis.

BACKGROUND: This systematic review examines the feasibility and safety of implementing Enhanced recovery after Surgery (ERAS) protocols in children. STUDY DESIGN: A systematic search of Medline, PubMed, and the Cochrane library for papers describing ERAS implementation in children between January 2000 and January 2021. The systematic review was performed according to the PRISMA statement. The meta-analysis was done using R Software (Ver 4.0.2). p value of < 0.05 was considered statistically significant. RESULTS: Sixteen studies, describing a total of 1723 patients, were included in the meta-analysis. An average of 15 (range 11-16) relevant components were implemented with an overall compliance close to 84%. The time to initiate feeds and reach full enteral nutrition was reduced in ERAS group with mean difference (MD) of - 21.20 h (95% CI - 22.80, - 19.59, p < 0.01), and - 2.20 days (95% CI - 2.72, - 1.71, p < 0.01), respectively. The use of opioids for postoperative analgesia was reduced with MD of -0.86 morphine equivalents mg/kg (95% CI - 1.40, - 0.32, p < 0.01). The length of hospital stay showed a significant reduction with MD of -2.54 days (95% CI - 2.94, - 2.13, p < 0.01). There was no difference in the complication and readmission rates between the groups. CONCLUSION: ERP implementation in pediatric perioperative care is a viable option in a variety of surgical settings. There is clear evidence of a decrease in hospital stay duration with no increase in complication or readmission rates. The length of hospital stay reduced in inverse proportion to the number of ERAS elements implemented. Parental satisfaction is increased by initiating enteral feeding early, minimizing catheter and drain use, and reducing opioid use.

Efficacy of Core Needle Biopsy in the Diagnosis of Pediatric Extracranial Solid Malignancies: A 10-Year Study.

Introduction: Core needle biopsies of solid masses in children are a minimally invasive technique. It guides to a definitive diagnosis and facilitates management. Aims and Objectives: To determine the accuracy, sensitivity, and specificity of core needle biopsies in diagnosing pediatric solid masses. Materials and Methods: A retrospective analysis of 430 children, who underwent core needle biopsy for solid masses between January 2007 and December 2016 at CMC Vellore, was done. Results: Retroperitoneal and intra-abdominal masses constituted 66% of cases. Real-time image guidance was used in 44% of cases. An accurate diagnosis was obtained in 93.6% of cases, while results did not correlate with the final diagnosis in 3.4%. Three percent had inadequate or necrotic tissue. None of the children had postprocedure complications. Conclusion: Core needle biopsies serve as good diagnostic modality, with minimal risks, in making a conclusive diagnosis and deciding on the line of management.

Pudendal nerve injury in men with fecal incontinence after radiotherapy for prostate cancer.

BACKGROUND: The precise etiology of fecal incontinence (FI), which occurs frequently following external beam radiotherapy (EBRT) for prostate carcinoma is unknown. It is possibly related to pelvic nerve injury. The aim of this study was to assess the incidence of pudendal nerve dysfunction in men with FI after EBRT for prostate cancer compared to men with FI but no history of EBRT. MATERIAL AND METHODS: Data were evaluated from 74 men with intact anal sphincters on endo-anal ultrasound (17 post-EBRT) who had been investigated for FI at a tertiary center. Wexner incontinence scores, pudendal nerve function, anorectal manometry, and rectal sensitivity were compared between the two patient groups. RESULTS: Post-radiotherapy patients were older (77±6 vs. 62±17 years, p<0.005) and had worse incontinence than those with no history of radiotherapy (Wexner score; 13±3 vs. 8±4; p<0.005). Bilateral pudendal nerve terminal motor latency (PNTML) was abnormal in 87% of radiotherapy versus 22% of non-radiotherapy patients (p<0.001) and the significant difference persisted even after correction for age differences. Anal sphincter pressures and rectal sensitivity for both groups were similar. CONCLUSION: There is a markedly higher incidence of pudendal nerve dysfunction in men with FI after EBRT for prostate cancer compared with men with FI from other etiologies. The increased severity of incontinence in radiotherapy patients is not matched by alterations in either anal sphincter pressures or rectal sensitivity compared to FI in non-ERBT patients.

Evidence that two distinct crypt cell types secrete chloride and potassium in human colon.

BACKGROUND: Human colon may secrete substantial amounts of water secondary to chloride (Cl(-)) and/or potassium (K(+)) secretion in a variety of diarrhoeal diseases. Ion secretion occurs via Cl(-) and K(+) channels, which are generally assumed to be co-located in the colonocyte apical membrane, although their exact cellular sites remain unclear. OBJECTIVE:  To investigate the location of apical Cl(-) (CFTR) and apical K(+) (large conductance; BK) channels within human colonic epithelium. DESIGN: Whole-cell patch clamp recordings were obtained from intact human colonic crypts. Specific blockers of K(+) channels and CFTR identified different types of K(+) channel and CFTR under resting conditions and after stimulating intracellular cAMP with forskolin. The BK channel ß3-subunit was localised by immunostaining. RESULTS: Two types of crypt cells were identified. One (73% of cells) had whole-cell currents dominated by intermediate conductance (IK) K(+) channels under resting conditions, which developed large CFTR-mediated currents in response to increasing intracellular cAMP. The other (27% of cells) had resting currents dominated by BK channels inhibited by the BK channel blocker penitrem A, but insensitive to both forskolin and the IK channel blocker clotrimazole. Immunostaining showed co-localisation of the BK channel ß3-subunit and the goblet cell marker, MUC2. CONCLUSIONS: In human colon, Cl(-) secretion originates from the dominant population of colonocytes expressing apical CFTR, whereas K(+) secretion is derived from a smaller population of goblet cells expressing apical BK channels. These findings provide new insights into the pathophysiology of secretory diarrhoea and should be taken into account during the development of anti-diarrhoeal drugs.

Assessment of Quality of Life and Functional Outcomes of Operated Cases of Hirschsprung Disease in a Developing Country.

PURPOSE: Children treated for Hirschsprung disease (HD) are adversely affected by fecal incontinence and soiling. This can be detrimental to their physical, psychosocial quality of life (QoL) and impacts the normal functioning of their family. QoL studies in HD are predominantly from developed countries. We measured general quality of life, impact on family and functional bowel status using validated questionnaires in HD children in a developing country. METHODS: Patients with HD, treated in a tertiary paediatric institution in India between 2010 and 2017, were identified. Patients and/or their proxy completed the Pediatric Quality of Life and Family Impact Module questionnaires. Functional outcomes were assessed using Rintala's score. RESULTS: A 86 children and their parents participated in the study. Majority had rectosigmoid disease (67.4%) and underwent Soave's endoanal pull through (74.4%). A 21% of patients had low Rintala score indicating poor functional bowel outcomes. Only 11% of children had poor QoL scores. Family functioning outcomes were also severely affected in the same subgroup of patients. There was statistically significant correlation between Rintala score and QoL scores (p-value<0.001). Disease severity, type of surgery, and duration of follow-up did not have a statistically significant impact on the QoL. CONCLUSION: QoL in children with HD was comparable to the general population. Bowel dysfunction affects a notable number of children and was the most significant determinant of poor QoL.

Unusual variant of pseudo prune belly syndrome.

Unilateral pseudo prune belly syndrome (PPBS) is a rare variant with only two other cases found in the main literature until. We present a 9-month old boy with left-sided lax abdominal wall, undescended testes and major vesicoureteric reflux involving only the left side. He underwent left orchidopexy and left end ureterostomy followed by left nephrectomy. Unilateral variant supports the theory of mesodermal arrest as a cause for prune belly syndrome. Treatment is individualised and prognosis is relatively better when compared with other variants of PPBS.

Intramural duodenal haematoma with mucosal prolapse causing intestinal obstruction.

Intramural small bowel haematoma is a rare cause of intestinal obstruction in children. Coagulation disorders or anticoagulant therapy are the most common cause followed by blunt trauma. A one and half-year-old boy, with known case of gastro-oesophageal reflux disease had undergone upper gastrointestinal endoscopy and biopsy. Four days later, he presented to us with clinical features of small bowel obstruction. CT of the abdomen showed features suggestive of haemorrhagic duplication cyst. Explorative laparotomy revealed 15-20 cm of bowel from the third part of the duodenum to proximal jejunum filled with clotted blood and thinned out serosa. There was no evidence of intraluminal blood in the distal bowel loops. Resection of the involved bowel with primary anastomoses was done. Histopathological examination of bowel revealed intramural haematoma associated with prolapse of the mucosa. There was no evidence of duplication cyst or vascular malformations. Postoperative period was uneventful.

Transanal haemorrhoidal dearterialization for the treatment of grade III and IV haemorrhoids: a 3-year experience.

BACKGROUND: Transanal haemorrhoidal dearterialization (THD) is increasingly perceived as an effective and better tolerated alternative to excisional haemorrhoidectomy. The aim of this study was to evaluate outcomes and the patient experience of THD in an Australian population with grade III or IV haemorrhoids. METHODS: A retrospective review of prospectively maintained database on patients who had undergone THD over a 3-year period was performed. Data were collected on demographics, operative data, complications, recurrences and readmissions, postoperative pain and further interventions. Patient perceptions and satisfaction with the procedure were assessed with a telephone survey. RESULTS: A total of 85 patients with a mean age of 55 (±14) years with grade III (85%) or grade IV (15%) haemorrhoids underwent THD. Indications for surgery were predominantly bleeding (87%) and prolapse (41%). Median outpatients follow-up was 42 days and median telephone follow-up was 802 days. Median operating time was 25 min (±12). Twenty-four per cent of patients suffered complications, including postoperative bleeding (7%), constipation (7%), local sepsis (6%), anal fissure (5%) and temporary incontinence (2%). Severe postoperative pain occurred in 16% of the patients. The symptom recurrence rate was 19% and reintervention rate was 14%. About 98.8% of patients reported good or excellent overall satisfaction with the procedure. CONCLUSION: THD is a relatively new technique for the treatment of haemorrhoids, which is increasingly being used as an alternative to excisional haemorrhoidectomy. This study shows that patients' satisfaction with THD is high despite a moderate complication and recurrence rate and significant incidence of postoperative pain.

Enteropathy associated T-cell lymphoma presenting with multiple episodes of small bowel haemorrhage and perforation.

Enteropathy-associated T cell lymphoma (EATCL) is an intestinal neoplasm of intra-epithelial T lymphocytes associated with coeliac disease. Although the incidence is rare, EATCL runs an aggressive disease course and produces multi-focal ulcerative lesions most commonly in the proximal small bowel. As such, patients may present with intestinal perforation, obstruction or haemorrhage. Management of EATCL requires a combination of early diagnosis and treatment by surgical resection followed by chemotherapy to achieve treatment success. Overall however, the treatment completion rate remains at 50% and EATCL carries a poor prognosis with a 5-year survival rate of <20%.
