Management of intussusception in children: A comparative study of hydrostatic reduction with saline under ultrasound guidance versus laparoscopic assistance.

Introduction: Intussusception is a common cause of intestinal obstruction in infants and children. Ultrasound-guided hydrostatic reduction (USGHR) with saline is considered the gold standard with a success rate of more than 90%. Hydrostatic reduction with laparoscopic assistance has its own advantage of direct visualisation, assessment of bowel vascularity and controlled distension. The choice of procedure depends on available resources and surgeon's preference. This study aims to compare the outcomes of the two methods, i.e., laparoscopic-assisted hydrostatic reduction (LAHR) and USGHR under general anaesthesia (GA). Materials and Methods: This was a prospective study carried out at two different centres over a 3-year period. All patients of intussusception were managed by either hydrostatic reduction with saline under ultrasound guidance or hydrostatic reduction with laparoscopic assistance. Both the procedures were done in operation theatre under GA. The operating time and amount of fluid used for reduction were noted. Results: There were 27 patients in Group 1 (USGHR) and 20 patients in Group 2 (LAHR). The two groups were similar in terms of demographic parameters. The various outcomes such as number of attempts for reduction, fluid required for reduction, time to start oral feeds, complication and length of stay were similar in both the groups. The mean operating time for Group 1 was 19.4 ± 4.5 min and for Group 2 was 34.9 ± 4.8 min (P < 0.001). Conclusion: Both the procedures fare equally in terms of outcome except mean operating time, therefore, LAHR is a good alternative to USGHR in resource-poor nations where logistics of intraoperative ultrasound may not be present.

Minimal access surgery of corrosive and thermal strictures of the foregut.

Background and Aim: : Conventional surgery for caustic/thermal strictures (CS/TS) entails considerable trauma, which may be mitigated by minimal access surgery (MAS). Experience with its use in CS/TS is both heterogeneous and limited, hence, warrants a comprehensive review. Methods: : Medical literature/indexing databases were systematically searched for pertinent articles published in English, from 1990 to 2021, and analysed. Results: : Fifty relevant articles, pertaining to over 200 patients, were found. They showed that MAS is feasible in CS/TS management. It reduces the access damage in chest and abdomen whilst facilitating resection or bypass of the affected gut segment through different combination of operations, sequence of steps, conduits and routes. The procedures range from completely minimal access to hybrid ones, with reduced complications and faster recovery. Hybrid procedures prove as expeditious as open ones. Conclusions: : MAS proves efficacious in restoring alimentary continuity in corrosive/thermal strictures of the foregut.

Influence of Interstitial Cells of Cajal in Congenital Ureteropelvic Junction Obstruction.

BACKGROUND: The etiopathogenesis of congenital ureteropelvic junction obstruction (UPJO) has been inconclusive in spite of the numerous studies carried out to find the possible causative factor. The results of different studies have been conflicting and contradictory. It has been postulated that the interstitial cells of Cajal (ICC) are the pacemaker cells located in the ureteropelvic junction (UPJ) and regulate the peristalsis in this region. Paucity of these cells may be one of the causative factors for congenital UPJO although there is no clear consensus on this issue. Therefore, the present study has been carried out to ascertain the role of ICC as one of the possible etiological factors for congenital UPJO. The aim of this study is to first identify the presence of ICC at UPJ, second to compare the average number of ICC in congenital UPJO with a control population without UPJO, and third to ascertain whether any correlation exists between the number of ICC and postoperative improvement in function of the affected kidney. MATERIALS AND METHODS: A total number of 30 patients who underwent dismembered Anderson-Hynes pyeloplasty for congenital UPJO between June 2016 and November 2017, were compared with seven controls who underwent nephroureterectomy for various other reasons. The specimen was subjected to immunohistochemistry (IHC), and a quantitative comparison was made for the ICC between cases and controls. The preoperative and postoperative function was evaluated by renal diuretic scintigraphy. RESULTS: The disease was more common among males in the ratio of 6.5:1, and there was a predominance of the left-sided involvement. In the studied cases, the average number of ICC seen for every high-power field (hpf) was 4.86 ± 0.76/hpf, whereas in control it was 11.74 ± 0.86/hpf (P = 0.04). The postoperative outcome, as measured by the improvement in split renal function, did not have any correlation with the number of ICC. CONCLUSION: The ICC are present at the UPJ and can be detected by immunohistochemistry due to their CD117 positivity. These cells are significantly low at this site in cases of congenital UPJO when compared to controls without any obstruction. The number of ICC bears no correlation to the postoperative improvement in function.

Persistent Mullerian Duct Syndrome: A rare clinical entity.

Persistent Mullerian duct syndrome(PMDS) is a rare clinical entity in the wide spectrum of disorder of sexual differentiation (DSD), often termed as intersex disorder.

Mucopolysaccharidosis type I disguised as rickets.

A 16-year-old boy with widening of the large joints of the extremities and bilateral genu valgum had been extensively treated with oral vitamin D, with little clinical benefit. A diagnosis of vitamin D-resistant rickets was considered initially but a thorough clinical examination and skeletal survey was suggestive of mucopolysaccharidosis. The diagnosis was confirmed biochemically and subtype classification pointed toward the type I variety of the storage disorder. Absence of mental retardation is very unusual in mucopolysaccharidosis type I, which itself is an uncommon clinical entity. This particular disease can be misdiagnosed as vitamin D-resistant rickets in the absence of thorough systemic examination and an attentive look at the skeletal surveys. Spondyloepiphyseal dysplasia is another close differential of mucopolysaccharidosis and it should be ruled out in all cases of suspected spondyloepiphyseal dysplasia.

Haemorrhagic pericardial effusion in type I Gaucher's disease.

Gaucher's disease is a rare lysosomal storage disorder. Excess accumulation of glucosylceramide predominantly occurs in abdominal viscera. Cardiac involvement is rare, though they generally represent as restrictive cardiomyopathy and pericarditis. Our case, a 19-year old boy initially presented with hepatosplenomegaly but later diagnosed with haemorrhagic pericardial effusion. Enzyme supplementation gives successful outcome but our case was managed symptomatically with pericardiocentesis.
