A new variant of esophageal atresia with tracheoesophageal fistula and duodenal atresia: A diagnostic dilemma
(Springer Verlag, 1997) C.K. Sinha; A.N. Gangopadhyay; S.P. Sahoo; S. Chooramani Gopal; D.K. Gupta; S.P. Sharma
A new variant of esophageal atresia (EA) with tracheoesophageal fistula (TEF) associated with duodenal atresia is reported. The TEF was between the lower pouch and the trachea, with a cystic dilatation in the midportion. The tracheal end of the fistula was obstructed by a membranous septum at both ends of a cystic dilatation, leading to a diagnosis of pure EA (gasless abdomen). After the lower pouch was opened beyond the cystic dilatation, 100 ml nonbilious fluid was obtained. A laparotomy revealed a type III atresia of the first part of the duodenum.
A rare association of diphallus, colonic duplications, ileal atresia, and an anorectal malformation
(1996) S.P. Sharma; A.N. Gangopadhyay; D.K. Gupta; S. Chooramani Gopal; R.N. Dash; C.K. Sinha
Diphallus is a rare congenital anomaly that is often associated with various other anomalies of the midline structures of the posterior portion of the body. We report a unique case of a 1-day-old male with complete diphallus, incomplete bilateral tubular duplications of the colon, ileal atresia, and an anorectal malformation.

(2010) A.N. Gangopadhyay; A. Pandey; N. Rastogi; M.B. Mandal; S.C. Gopal; D.K. Gupta; A. Srivastava
Objective: There are no in vitro studies of congenital pouch colon (CPC) associated with anorectal malformation (ARM) to understand its mechanism of contractility. There is no consensus regarding the utilization of the CPC in repair of anorectal malformation. In view of the above, it was decided to carry out detailed in vitro physiological study of the excised CPC. Method: The excised specimens of CPC were taken and 15- to 20-mm long both longitudinal and transverse strips of muscle were obtained both from the proximal and distal part. Contraction was recorded using software chart-5 for windows. Drugs used were acetylcholine, histamine, adrenaline, atropine and pheniramine maleate. The amplitude of contractions was converted to tension gram and then the tension so developed was expressed as tension per unit mass (per gram of wet tissue). Results: There were total of 21 specimens of high ARM with CPC. Five specimens were of the complete pouch, which did not show a response to any drug and the remaining 16 had an incomplete pouch. The mean longitudinal and circular muscle contractions of these 16 samples were statistically higher for the proximal segment than the distal segment both for acetylcholine and histamine. The effect of atropine was not significant but that of adrenaline and pheniramine maleate were significant on the distal segment muscle. Conclusion: Congenital pouch colon being deficient or having poorly developed receptors in their wall can not function properly as a reservoir for faeces and, hence, it should be excised to allow adequate function. © 2010 The Authors.

Abdominal cocoon in children: A report of four cases
(W.B. Saunders, 1996) S.P. Sahoo; A.N. Gangopadhyay; D.K. Gupta; S.C. Gopal; S.P. Sharma; R.N. Dash
Abdominal cocoon is a rare cause of intestinal obstruction. The authors report four cases (3 boys, 1 girl; age range, 6 to 8 years) that presented with features of intestinal obstruction. There was no history of previous surgery, peritonitis, or prolonged drug intake in any of these cases. One patient presented with acute intestinal obstruction and gangrene of bowel. The etiology, preoperative diagnosis, and management of this condition are discussed.

Acute gastric volvulus in neonates - A diagnostic dilemma
(2008) V.D. Upadhyaya; Ajay Narayan Gangopadhyay; A. Pandey; V. Kumar; S.P. Sharma; D.K. Gupta
Introduction: Gastric volvulus is a rare, potentially life-threatening condition, which is difficult to diagnose. This study presents a series of acute gastric volvulus in neonates with the aim of describing this rare disease and its varied clinical manifestations. Material and Methods: The data of all neonates presenting with acute gastric volvulus between January 2001 and January 2007 was retrospectively reviewed. Diagnosis was made on suspicion and was documented by a barium study. All patients were operated by open anterior gastropexy with or without a feeding gastrostomy. Results: Four patients were male and 1 was female. All were treated with gastropexy with or without feeding gastrostomy. Four patients recovered well after surgery. There was one postoperative death. Conclusion: Gastric volvulus is extremely rare in neonates but it should be considered in the differential diagnosis after sudden onset or recurrent vomiting in the pediatric age group. Early diagnosis and treatment gives excellent results. © Georg Thieme Verlag KG Stuttgart.

Assessment and comparison of fecal continence in children following primary posterior sagittal anorectoplasty and abdominoperineal pull through for anorectal anomaly using clinical scoring and MRI
(W.B. Saunders, 2016) A.N. Gangopadhyay; Vaibhav Pandey; D.K. Gupta; S.P. Sharma; Vijayendar Kumar; Ashish Verma
Introduction We aimed to compare and contrast these main surgical procedures for ARM in terms of structural outcome through pelvic MRI & functional outcome through Kelly's scoring. Material and method A prospective study was conducted from August 2011 to July 2013 including all the cases of ARM managed in single stage (operated by one surgeon, first author) since 1995 that came for follow up at age of 3 years or more. Patients were divided in three groups: Group 8.A, PSARP (60 patients); Group B, Abdomino-PSARP (40 patients); and Group C, APPT (40 patients). The functional assessment of anal continence was carried out at the age of 3 years or more using Kelly's method. Structural assessment was done by 1.5-T Magnetic Resonance Imaging (MRI). Results In 24 patients with rectobulbar fistula, 71.5% of Group A patients had good continence. In 50 patients with rectoprostatic fistula, 73.7% of Group A, 70% of group B and only 36% of Group C had good outcomes. Better development of each muscle was associated with better outcomes in terms of anal continence (P = 0.001). Conclusion There is better outcome with PSARP and Abdomino-PSARP in patients with rectobulbar and rectoprostatic fistula. MRI is a valuable modality for postoperative structural analysis of patients with ARM and is also useful for predicting the long term functional outcome of these cases. © 2016 Elsevier Inc.

Atresia of ileocecal junction, ileocecal valve: Rare variants of bowel atresia
(2009) Punit Srivastava; A.N. Gangopadhyay; D.K. Gupta; S.P. Sharma; Vijay D. Upadhyaya; Vijayendra Kumar; Richa Jaiman
Atresia of ileocecal junction and isolated atresia of ileocecal valve are rare types of intestinal atresia with very few reports in literature. We report two such cases. Radiology showed dilated ileal segment and distal micro colon in both the cases. At laparotomy there was atresia of ileocecal junction in the first case and isolated ileocaecal valve atresia with normal ileocecal junction in the other case. Both the babies were managed by ileocolic resection with an end to end anastomosis. The prognosis of ileocecal atresias is satisfactory.
Carcinoma of the rectum in children
(1996) S.P. Sahoo; A.N. Gangopadhyay; D.K. Gupta; S.C. Gopal; C.K. Sinha; S. Gupta; M. Kumar
Two cases of carcinoma of the rectum in children (10 and 11 years old) are presented. Both cases presented as acute intestinal obstruction with the history of bleeding per rectum, constipation, abdominal distention, and loss of weight and appetite. Carcinoma of the colon and rectum in children is rare. Its clinical, pathologic, and biological characteristics are different than those of adults. The prognosis is poorer in children, the reason for which is explained, and its management is briefly discussed.
Chronic bilious vomiting in children in developing countries due to high bowel obstruction: Not always malrotation or tuberculosis
(2010) Anand Pandey; V. Kumar; A.N. Gangopadhyay; S.P. Sharma; S.C. Gopal; D.K. Gupta; S.C.U. Patne
Background: Bilious vomiting, in conjunction with abdominal pain is considered to be a surgical problem, unless proved otherwise. In children, besides tuberculosis (TB), we have found jejunal stricture (JS) due to non-specific jejunoileitis (NSJI) to be an important cause of chronic high small bowel obstruction and bilious vomiting. Materials and methods: In this retrospective study, the records of all children with complaint of intermittent bilious vomiting and failure to thrive were evaluated. Investigations included oral contrast study, ultrasound abdomen, chest X-ray and Mantoux test. Final confirmation was made at laparotomy. Treatment included jejuno-jejunal resection and anastomosis. Histopathology of the specimen was done to look for caseation, granuloma formation and other details. Results: Out of total 100 patients with the complaint of bilious vomiting, 25 were having JS. Radiologic confirmation was possible in 19 (76%) patients of JS. No patient had evidence of TB as per our protocol. Histopathology revealed non-specific ischemic changes in all specimens. Conclusion: Jejunal stricture due to NSJI is a common entity in our setup leading to bilious vomiting. Contrast study can provide high index of suspicion in most of the patients. The diagnosis must be confirmed after proper histopathological examination. The results of the surgery are excellent. © 2009 Springer-Verlag.

(Taylor and Francis Ltd., 2019) P. Kumar; R. Prasad; A. Choudhary; D.K. Gupta; V.N. Mishra; A.K. Vishwakarma; A.K. Singh; P.K. Srivastava
In the present study, random forest regression (RFR), support vector regression (SVR) and artificial neural network regression (ANNR) models were evaluated for the retrieval of soil moisture covered by winter wheat, barley and corn crops. SVR with radial basis function kernel was provided the highest adj. R2 (0.95) value for soil moisture retrieval covered by the wheat crop at VV polarization. However, RFR provided the adj. R2 (0.94) value for soil moisture retrieval covered by barley crop at VV polarization using Sentinel-1A satellite data. The adj. R2 (0.94) values were found for the soil moisture covered by corn crop at VV polarization using RFR, SVR linear and radial basis function kernels. The least performance was reported using ANNR model for almost all the crops under investigation. The soil moisture retrieval outcomes were found better at VV polarization in comparison to VH polarization using three different models. © 2018, © 2018 Informa UK Limited, trading as Taylor & Francis Group.

(2007) A.N. Gangopadhyay; Vijai D. Upadhyaya; D.K. Gupta; S.P. Sharma; Vijayendra Kumar
Objective. The ascariasis is one of the most cosmopolitan intestinal parasite infections and it can be in inhospitable regions inhabited by human being, but its biggest prevalence is observed in the tropical and subtropical areas. Intestinal obstruction has been estimated to occur in 2 per 1000 ascaris-infected children per year. We are presenting a study emphasizing the conservative treatment for complete intestinal obstruction due to roundworms without sign and symptom of peritonitis and perforation. Methods. A total of 22 patients of roundworm obstruction partial or complete without signs of and symptoms of peritonitis were admitted in the Department of Pediatric Surgery IMS, BHU Varanasi India in the period form 2003 - 2005. Patients were put nil by mouth, intravenous fluid, antibiotics, piperazine salt through nasogastric tube and glycerine + liquid paraffin emulsion enemas and were evaluated for duration of hospital stay, rate of conversion to surgical treatment and complications. Results. 19 (86%) patients were treated successfully with conservative line of management. Only 3 patients required surgical intervention. No mortality, complication and mean hospital stay was 4.1 days (range 4 - 5 days). Conclusion. Round worm intestinal obstruction can be effectively treated by conservative line of management. © 2007 Dr. K C Chaudhuri Foundation.

(Institute of Electrical and Electronics Engineers Inc., 2016) D.K. Gupta; R. Prasad; P. Kumar; V.N. Mishra; P.K.S. Dikshit; S.B. Dwivedi; A. Ohri; R.S. Singh; V. Srivastav; Prashant Kumar Srivastava
The aim of present study is to estimate the crop variables by means of high performing technique like adaptive neuro-fuzzy inference system (ANFIS) using the bistatic scatterometer data. An outdoor 4×4 m2 crop bed of rice crop was prepared for performing all the experiments. The bistatic measurements were carried out over the entire growing stages of the rice crop from transplanting to ripening stage at the angular range of 200 to 700 with the steps 50 at both HH- and VV-polarizations in X-band. The ANFIS algorithm was used for the estimation of rice crop variables. The observed bistatic scattering coefficients and crop variables (biomass, leaf area index, plant height and chlorophyll content) were interpolated with the phenological stages of the rice crop. The 80% data sets were used for training while the remaining 20% were kept separately for the testing purposes. The bistatic scattering coefficients were used as the input data sets and the rice crop variables as the target data sets of fuzzy inference system for both the polarizations. The estimated values were found closer to the observed values of rice crop variables that indicate a satisfactory performance of ANFIS algorithm for estimating rice crop variables. © 2015 IEEE.

Cystic variants of atypical mesoblastic nephromas are very rare. The present communication deals with two such cases encountered in 3- and 6-month-old patients. The literature is briefly reviewed. The need for proper diagnosis of this tumor to distinguish it from cystic nephroma and Wilms' tumor is highlighted.
Double coin in esophagus at same location and same alignment - A rare occurrence: A case report
(2009) Eti V. Upadhyaya; Punit Srivastava; Vijay D. Upadhyaya; A.N. Gangopadhyay; S.P. Sharma; D.K. Gupta; Zaheer Hassan
Coin is the most common foreign body swallowed by pediatric age group. The multiple coin swallowing is extremely rare and very few cases had been reported in English literature. Most of them were present at different site and had different alignment in the esophagus. The location of the coin (trachea vs. esophagus) is commonly determined by the alignment of the coin on radiographic studies. A 4-year-girl was presented to us with history of coin ingestions one day back without any respiratory distress. On radiological study there was suspicion of two coins on same location and alignment. The diagnosis was confirmed after removal. The both coin was removed successfully by esophagoscopy. Unexpected second foreign bodies in pediatric esophageal coin ingestions are rare and it is mandatory to do post operative radiography after removal to exclude duplex coin or tracheal coin. We are presenting this case because of its rarity, difficulty in diagnosis especially when proper history is not available. © 2009 Upadhyaya et al; licensee Cases Network Ltd.
