Colonic duplication cyst with secondary septic peritonitis in a cat.

Case summary: A 5-month-old male castrated domestic shorthair cat was evaluated for acute onset of emesis. Abdominal radiographs identified a suspected colonic foreign body and abdominal-focused assessment with sonography for trauma, triage and tracking (AFAST) evaluation revealed a large amount of peritoneal effusion. Cytology of the peritoneal effusion was consistent with a septic exudate. An exploratory celiotomy identified a ruptured ileocecocolic mass and a resection and anastomosis was performed. No foreign material was identified and histopathology confirmed that the ruptured mass was a colonic duplication cyst. Recurrent septic peritonitis was diagnosed based on cytologic evaluation of fluid from a silicone bulb reservoir of a closed suction drain. No abnormalities were surgically identified, the cat recovered without complication, was discharged at 7 days postoperatively and has continued to remain healthy 8 months after surgical intervention. Relevance and novel information: To our knowledge, this is the first known instance of a histopathologically confirmed non-communicating colonic duplication cyst causing septic peritonitis in the veterinary literature.

Uncommon case of intestinal duplication cyst. Case report.

INTRODUCTION: Alimentary tract duplication is a rare congenital anomaly that can occur anywhere along the entire digestive tract. The incidence has been reported very low. Ileum is most common part of duplication. It is more common in childs and newborns. But some duplications remain 'silent' and clinicians often misdiagnose it because of the nonspecific clinical signs. PRESENTATION OF THE CASE: We present the case of a young girl suffering from abdominal pain for months,not getting benefit from medical treatment and was misdignosed as irritable bowel syndrome, after investigation cystic lesion was discovered so she underwent explorative laparatomy and intestinal duplication was indentified which was completely resected with end to end ananstomosis. DISCUSSION: The intestinal duplication cysts are unusual malformation. The clinical presentation is not specific and depends on the location.The surgical treatment includes resection of the duplicated bowels. Surgical intervention is the treatment of choice. CONCLUSION: It is important to include intestinal duplication in the differential diagnosis of acute abdomen.

Tubular intestinal duplication extending from the stomach to the ileum associated with multiple intestinal atresia and situs inversus: a case report.

BACKGROUND: Duplication of the alimentary tract can occur in any of its parts. For duodenal duplication, complete resection is particularly difficult when the ampulla of Vater is on the duplicated lumen and a deliberate management is necessary. CASE PRESENTATION: A 0-day female baby was referred to our department due to abdominal distention. The X-ray examination showed dextrocardia and opacity of the liver on the left side and abdominal ultrasonogram revealed remarkable intestinal dilatation. Therefore, urgent laparotomy was performed on the day of birth. Complete situs inversus of the abdominal organs was revealed, and the origin of the jejunum was on the left side and was accompanied by tubular intestinal duplication. The origin of the duplicated intestine was at the pancreatic head's dorsal area. There were two points of type Шa atresia on the ileum. Therefore, we spared the duplicated intestine with a length of 3 cm to secure the passage of the biliary and pancreatic juices by a functional-side-to-side anastomosis with a 45-mm Endo-GIA™ camel load (Medtronic, Minneapolis, MN, USA). The ileum was transected at the distal side of the atresia point, and end-to-end jejunoileostomy was performed. Postoperative gastrointestinal series revealed remnants of the duplicated alimentary tract on the dorsal area of the stomach. CONCLUSIONS: Identifying the position of the ampulla of Vater is crucial in the surgery of alimentary tract duplication with duodenal involvement. However, in the present case, it was difficult to identify whether the ampulla of Vater was on the true or duplicated lumen, and we had to spare the duplicated duodenum. Stapler anastomosis could be performed safely even in neonatal cases.

Acute peritonitis caused by the acute pancreatitis of an ectopic pancreas in a jejunal duplication, in an adult with intestinal malrotation: a case report.

BACKGROUND: Intestinal duplication and ectopic pancreas are two rare independent congenital anomalies. Few reports describe cases of patients with ectopic pancreas in an intestinal duplication causing acute peritonitis. CASE PRESENTATION: A 31-year-old man was admitted to the hospital for epigastric pain. The patient was diagnosed with acute peritonitis caused by the acute pancreatitis of an ectopic pancreas in a jejunal duplication, with intestinal malrotation. The patient underwent the partial resection of the jejunum and Ladd's procedure. The histopathological findings indicated ectopic pancreatitis in the jejunal duplication. CONCLUSIONS: We presented the case of acute peritonitis caused by the acute pancreatitis of an ectopic pancreas in a jejunal duplication in an adult with intestinal malrotation. Surgery is the primary treatment and is necessary for a definitive diagnosis.

A Rare Case of True Pancreatic Cyst.

Pancreatic cysts can be true or pseudocysts. True pancreatic cysts in children are rare clinical entities. We present a 23-month-old boy with a cystic lesion in the distal body and tail of the pancreas which on histopathology was found to be a rare true congenital simple cyst of the pancreas.

Case report: Ileocecal preservation for multiple small intestinal duplications.

Small-intestinal duplication is a rare congenital developmental anomaly that is mainly single; multiple small-intestinal duplications are rare. Most malformations are located in the ileocecal region. The primary surgical treatment is complete resection of the malformations and adjacent intestinal ducts. However, the ileocecal junction plays an important role in children, and it is difficult to preserve it; multiple intestinal repairs increase the risk of postoperative intestinal fistula, which is a challenge for pediatric surgeons. Herein, we report a case of ileocecal preservation surgery for the treatment of multiple small intestinal duplication malformations near the ileocecal area. The child underwent laparoscopically assisted cyst excision and multiple intestinal repairs and had good postoperative recovery and follow-up.

Giant teratoma with isolated intestinal duplication in adult: A case report and review of literature.

BACKGROUND: A combination of diseases is a rare phenomenon. Their clinical manifestations can vary, and the diagnosis can be challenging. Intestinal duplication is a rare congenital malformation, whereas retroperitoneal teratoma is a tumor in the retroperitoneal space, derived from the remaining embryonic tissue. There are relatively few clinical findings on adult retroperitoneal benign tumors. It is hard to believe that these two rare diseases can happen to the same person. CASE SUMMARY: A 19-year-old woman complaining of abdominal pain with nausea and vomiting was admitted. Abdominal computed tomography angiography was suggested for invasive teratoma. Intraoperative exploration revealed that the giant teratoma was connected to an isolated intestinal tract in the retroperitoneum. The postoperative pathological examination revealed that mature giant teratoma was present with intestinal duplication. This was a rare intraoperative finding that was successfully treated surgically. CONCLUSION: The clinical manifestations of intestinal duplication malformation are various, and difficult to diagnose before the operation. The possibility of intestinal replication should be considered when intraperitoneal cystic lesions are present.

Duplicidad intestinal con diagnóstico ecográfico. Presentación de un caso

La duplicación intestinal es una afección poco frecuente que se diagnostica y resuelve durante los dos primeros años de vida. Pueden ser diverticulares, quísticas o tubulares, comunicadas y no comunicadas. Los síntomas varían con el tipo, tamaño, localización y mucosa que los tapiza. Este trabajo tiene como objetivo presentar el caso de una paciente pediátrica con diagnóstico de duplicidad intestinal ileal, en que las pruebas de imagen aportaron al diagnóstico definitivo. Se trata de una paciente femenina de 16 meses, que presentó dolor abdominal tipo cólico difuso, intermitente, heces sanguinolentas, distención abdominal e irritabilidad. En radiografía de abdomen simple se evidenció distensión de asas intestinales como niveles hidroaéreos y presencia de gas en recto. En ultrasonido se constató imagen quística hacia hipocondrio derecho, en íntimo contacto con asa intestinal adyacente, signo de la doble pared y nivel líquido-líquido. Se sugirió el diagnóstico de duplicidad intestinal ileal, que fue confirmado con biopsia, posterior a cirugía realizada. Es la ecografía la prueba de primera opción en el diagnóstico de esta afección. Muestra el signo de la doble pared con una capa ecogénica interna (epitelio) y una capa hipoecogénica externa que corresponde a las capas musculares. Los métodos de estudios imagenológicos son de vital importancia para su diagnóstico, es el ultrasonido abdominal quien proporciona un diagnóstico certero, siendo inocuo para el paciente.

Intestinal duplication is a rare condition that is diagnosed and resolves within the first two years of life. They can be diverticular, cystic or tubular, communicating and non-communicating. The symptoms vary with the type, size, location and mucosa that covers them. This research aims to present the case of a pediatric patient diagnosed with ileal intestinal duplication, in which imaging tests contributed to the definitive diagnosis. This is a 16-month-old female patient who presented with diffuse, intermittent colicky abdominal pain, bloody stools, abdominal distention, and irritability. A simple abdominal X-ray revealed distention of the intestinal loops, such as air-fluid levels and the presence of gas in the rectum. Ultrasound revealed a cystic image towards the right hypochondrium, in close contact with the adjacent intestinal loop, double wall sign and fluid-fluid level. The diagnosis of ileal intestinal duplication was suggested, which was confirmed with a biopsy after surgery. Ultrasound is the test of first choice in the diagnosis of this condition. It shows the double wall sign with an inner echogenic layer (epithelium) and an outer hypoechoic layer corresponding to the muscle layers. The methods of imaging studies are of vital importance for its diagnosis, it is the abdominal ultrasound that provides an accurate diagnosis, being harmless for the patient.

Duplicidad intestinal y diagnóstico diferencial prenatal de lesiones quísticas intraabdominales / Intestinal duplication and prenatal differential diagnosis of intra-abdominal cysts

Resumen ANTECEDENTES: Las duplicaciones del aparato digestivo son una variante poco frecuente de malformación congénita. Si bien la mejora de los equipos de ecografía ha aumentado la tasa diagnóstica, solo el 30% se diagnostican antes del nacimiento. El diagnóstico diferencial de lesiones quísticas intraabdominales es amplio e incluye, por ejemplo, a los quistes de ovario, colédoco, mesenterio o pseudoquistes de meconio. El tratamiento es quirúrgico mediante la resección y restauración de la continuidad intestinal. CASO CLÍNICO: Paciente de 32 años, con un embarazo previo y en el segundo trimestre del actual, con sospecha de un quiste de duplicación intestinal. El estudio genético no evidenció anomalía alguna. La lesión, de morfología quística tubular, fue aumentando progresivamente de tamaño conforme avanzaban las semanas de embarazo. En la semana 39 se indicó, por diabetes gestacional insulinodependiente, la inducción del parto. Nació un varón, asintomático, mediante parto eutócico, sin complicaciones. La ecografía abdominal, resonancia magnética nuclear y estudio del tránsito intestinal del periodo neonatal temprano confirmó el diagnóstico prenatal de sospecha. Mediante una laparoscopia exploradora, a las dos semanas de vida se practicó la resección del defecto que se reportó como: duplicación intestinal ileal, sin comunicación con la luz intestinal. El curso posoperatorio fue favorable. CONCLUSIONES: El diagnóstico prenatal de quistes de duplicación en el aparato digestivo está en aumento debido a la mejoría en las técnicas de diagnóstico prenatal. La valoración multidisciplinaria es decisiva para procurar una adecuada vigilancia médica del embarazo y del recién nacido.

Abstract BACKGROUND: Duplications of the digestive tract are a rare variant of congenital malformation that can occur anywhere in the digestive tract. Although improved ultrasound equipment has increased the diagnostic rate, only 30% are diagnosed before birth. The differential diagnosis of intra-abdominal cystic lesions is broad and includes, for example, cysts of the ovary, common bile duct, mesentery or meconium pseudocysts. Treatment is surgical by resection and restoration of intestinal continuity. CLINICAL CASE: 32-year-old patient, with a previous pregnancy and in the second trimester of the current pregnancy, with suspicion of an intestinal duplication cyst. The genetic study did not reveal any abnormality. The lesion, of tubular cystic morphology, progressively increased in size as the weeks of pregnancy progressed. Induction of labour was indicated in week 39 due to insulin-dependent gestational diabetes. An asymptomatic male was born by euthecological delivery, without complications. Abdominal ultrasound, nuclear magnetic resonance imaging and intestinal transit study of the early neonatal period confirmed the suspected prenatal diagnosis. By means of exploratory laparoscopy, at two weeks of life, resection of the defect was performed, which was reported as: ileal intestinal duplication, without communication with the intestinal lumen. The postoperative course was favourable. CONCLUSIONS: Prenatal diagnosis of duplication cysts in the digestive tract is increasing due to improved prenatal diagnostic techniques. Multidisciplinary assessment is crucial to ensure adequate medical surveillance of the pregnancy and the newborn.

A case report of a giant ileocecal cystic prolapse through the anus and literature review.

Intussusception refers to the invagination of a proximal loop of the bowel into an adjacent distal segment. This condition is rare in adults, especially when it involves a complete folding of the ileocecal area out of the body cavity. Meanwhile, enterogenous cysts are congenital malformations that are largely identified in childhood following symptoms of bowel obstruction. While surgical treatment is ultimately required for both diseases, deciding on the type of surgery and the right time to operate can be a challenge for clinicians. It is especially difficult to decide on treatment for an adult with the coincidental occurrence of both conditions and no definitive pathologic diagnosis prior to surgery. Here, we present the case study of a 19-year-old female patient who presented with a prolapsed anus due to intussusception caused by a large ileocecal mass. The patient was admitted to the emergency department with a "massive anal mass." She remained symptomatic after receiving conventional conservative treatment and had to undergo emergency surgery after developing an intestinal obstruction. While the patient's intraoperative condition also confirmed the preoperative CT findings, the situation became more complicated during surgery. The postoperative pathological report indicated the presence of an enterogenous cyst. After recovery from surgery, the patient was successfully discharged. Intussusception or intestinal obstruction caused by an intestinal mass is a surgical indication, and removal is the only way to cure the condition. This case study provides a helpful reference for general surgeons, especially anorectal surgeons, imaging physicians, and pathologists, and informs the diagnosis and treatment of this patient population.

Robot-Assisted Resection of Intestinal Duplication in Children.

Background: Intestinal duplication is the most common type of alimentary tract duplications in childhood. Laparoscopic-assisted surgery has become the main surgical procedure, but robot-assisted resection has rarely been reported; the aim of this study was to retrospectively present our experience with robot-assisted intestinal duplication excision using the Da Vinci Xi surgical system and discuss the technical points. Methods: In total, 49 patients who were diagnosed with intestinal duplication and underwent surgery from April 2020 to February 2022 in the Children's Hospital, Zhejiang University School of Medicine, were retrospectively analyzed. The data were collected including the clinical information of the patients, operative details, and postoperative outcomes. Results: Among these 49 patients, a total of 15 underwent robot-assisted surgery and 34 underwent laparoscopic-assisted surgery. For the robot-assisted surgery group, all the cysts were peeled off by complete endoscope, the integrity of the intestine was preserved and intestinal resection and anastomosis were not required. The operation time of 80 minutes for the robot-assisted group was not significantly longer than the 90 minutes for the laparoscopic-assisted surgery group(P > .05), but the mean time to take the liquid diet after surgery and the average length of postoperative hospital stay were significantly shorter (P < .05). Conclusion: Robot-assisted resection of intestinal duplication is safe and feasible and the refinement of the Da Vinci Xi surgical system was much better than that of the conventional laparoscopic equipment, resulting in significantly improved intraoperative and postoperative outcomes.

An unusual presentation of intestinal duplication mimicking torsion of Meckel's diverticulum: a rare report of a pediatric case.

BACKGROUND: Enteric duplication is a congenital disease that occurs throughout the entire gastrointestinal tract. Although it may sometimes cause intestinal volvulus, a few reports have described cases of enteric duplication twisted on itself. We experienced a rare pediatric case of long-segment tubular ileal duplication showing torsion. Torsion of enteric duplication is extremely rare. We herein report a pediatric case showing unusual torsion of ileal duplication requiring emergency surgery. CASE PRESENTATION: A 3-year-old boy presented with abdominal pain and vomiting. Contrast-enhanced computed tomography (CT) revealed a cystic luminal structure with a blind end and fluid collection in the pelvic cavity. CT also showed no findings of ileus or intestinal dilatation except for a cystic luminal structure. The preoperative diagnosis was torsion of Meckel's diverticulum. The patient underwent emergent explorative diagnostic laparoscopy. As a result, a necrotic luminal structure and bloody ascites were recognized, and small-scale laparotomy was performed. Long-segment ileal duplication was recognized. The long-segment tubular ileal duplication shared the anti-mesenteric side of the intestinal wall along one-third of its length. The residual two-thirds of its length was free from the ileum and its blind end was twisted in a manner that looked similar to Meckel's diverticulum. Normal ileum and the duplication, including the twisted necrotic portion, were resected, and ileal anastomosis was performed. The postoperative course was uneventful. A pathological examination confirmed the definitive diagnosis of enteric duplication. CONCLUSIONS: We reported the unusual presentation of intestinal duplication mimicking torsion of Meckel's diverticulum. Enteric duplication shows various clinical symptoms and presentations. We must understand that the classification of digestive enteric duplication is diverse with a variety of associated clinical symptoms.

Intestinal intussusception caused by intestinal duplication and ectopic pancreas: A case report and review of literature.

BACKGROUND: Intestinal intussusception caused by intestinal duplication and ectopic pancreas is extremely rare in the clinic and has not been reported previously. CASE SUMMARY: A 29-year-old man was admitted to the hospital for chronic abdominal pain and bloating. The preoperative diagnosis was intestinal obstruction and intussusception. Then, laparotomy, partial small intestinal resection and extraintestinal decompression were performed. Postoperative pathology confirmed intestinal duplication and ectopic pancreas. After surgery, the patient recovered well with no complications. No recurrence was observed after more than 5 mo of follow-up. CONCLUSION: We report a new case of a young male with intussusception caused by intestinal duplication and ectopic pancreas. Surgery is the main treatment for these conditions. This study aimed to raise awareness and provide information to improve the clinical management of this rare yet serious condition.

Congenital anomalies of the tubular gastrointestinal tract.

Congenital anomalies of the tubular gastrointestinal tract are an important cause of morbidity not only in infants, but also in children and adults.The gastrointestinal (GI) tract, composed of all three primitive germ layers, develops early during embryogenesis. Two major steps in its development are the formation of the gut tube (giving rise to the foregut, the midgut and the hindgut), and the formation of individual organs with specialized cell types.Formation of an intact and functioning GI tract is under strict control from various molecular pathways. Disruption of any of these crucial mechanisms involved in the cell-fate decision along the dorsoventral, anteroposterior, left-right and radial axes, can lead to numerous congenital anomalies, most of which occur and present in infancy. However, they may run undetected during childhood.Therapy is surgical, which in some cases must be performed urgently, and prognosis depends on early diagnosis and suitable treatment.A precise pathologic macroscopic or microscopic diagnosis is important, not only for the immediate treatment and management of affected individuals, but also for future counselling of the affected individual and their family. This is even more true in cases of multiple anomalies or syndromic patterns.We discuss some of the more frequent or clinically important congenital anomalies of the tubular GI, including atresia's, duplications, intestinal malrotation, Meckel's diverticulum and Hirschsprung's Disease.

Intestinal duplication isolated from the digestive tract: an entity to be considered. / Duplicación intestinal aislada respecto al tracto digestivo: una entidad a tener en cuenta.

OBJECTIVES: To review intestinal duplications isolated from the digestive tract. MATERIAL AND METHODS: Description of the 27 isolated intestinal duplication cases published; presentation of a new case. RESULTS: Intestinal duplication isolated from the digestive tract represents an extremely rare malformation. This type of duplication is not in close contact with any segment of the intestinal tract, and it has its own vascular pedicle. Preoperative diagnosis rates are lower than those found in classic duplications. In addition to the potential complications, malformation torsion is also to be considered. CONCLUSIONS: This infrequent variant is to be considered at differential diagnosis. Potential torsion should also be taken into account in order to decide when an asymptomatic patient should undergo surgery.

OBJETIVOS: Revisión de las duplicaciones intestinales aisladas, sin conexión con el tracto digestivo. MATERIAL Y METODOS: Se recopilan los 27 casos de duplicación intestinal aislada publicados hasta el momento y se presenta un nuevo caso. RESULTADOS: Las duplicaciones intestinales aisladas sin conexión con el tracto digestivo representan una variante de la malformación extremadamente rara. Este tipo de duplicaciones no están en contacto íntimo con ningún segmento del tracto intestinal y cuelgan de un pe­dículo vascular propio. Tienen menos tasa de diagnóstico prequirúrgico que las duplicaciones clásicas y a las posibles complicaciones hay que añadir la torsión de la malformación. CONCLUSIONES: Es interesante conocer esta variante infrecuente para considerarla en el diagnóstico diferencial. La posibilidad añadida de torsión debe tenerse en cuenta para decidir el momento de la cirugía en el paciente asintomático.

Pseudomyxoma peritonei originating from intestinal duplication: A case report and review of the literature.

BACKGROUND: Pseudomyxoma peritonei (PMP) is a rare mucinous neoplasm with a relatively low incidence of 1 to 2 per million individuals. It is typically characterized by a type of gelatinous ascites named "jelly belly". Most cases of PMP occur in association with ruptured primary mucinous tumors of the appendix (90%). Periodically, PMP can originate from mucinous carcinomas at other sites, including the colorectum, gallbladder, and pancreas. However, unusual origin can occur, as noted in this case report. CASE SUMMARY: A 52-year-old woman had an unusual derivation of PMP from intestinal duplication. The patient complained of abdominal distension and increasing abdominal girth. Abdominal contrast-enhanced computed tomography showed a mass in the greater omentum located on the left side of the abdomen, likely to be a cystic mass of peritoneal origin. A PMP diagnosis was presumed based on the specific signs of the mass with flocculent and stripe-like echoes in ultrasound images. Ultrasound-guided percutaneous aspiration suggested a high likelihood of PMP. Once the PMP diagnosis was recognized, identification of the origin of the primary tumor was indicated. Thus, an exploratory laparoscopy was performed. In the absence of a primary tumor of appendix origin, the diagnosis of a low-grade mucinous neoplasm of intestinal duplication origin was finally confirmed by histopathology. CONCLUSION: PMP is secondary to mucinous carcinomas of the appendix mostly. This case resulted from an unusual derivation from intestinal duplication.

Cystic Nontubular Jejunal Duplication Cyst Presenting As Acute Intestinal Obstruction: A Surgical Challenge.

Enteric duplication cysts are rare congenital anomalies that present with a vague constellation of symptoms such as vomiting and abdominal distension. Of these, cystic nontubular jejunal duplication cysts comprise an exceedingly small subset. Here, we delineate the case of a two-month-old female baby who presented with symptoms suggestive of acute intestinal obstruction. Radiological workup divulged a cystic lesion, which was subsequently confirmed to be a cystic nontubular jejunal duplication cyst with extensive intestinal wall sharing. Surgical excision was planned but posed a remarkable surgical challenge due to intestinal wall sharing and the cyst's exceedingly fibrotic nature.

Quiste enterogénico y agenesia renal en la edad adulta / Enterogenic cyst and renal agenesis in adulthood

Introducción: Los quistes enterogénicos son malformaciones producidas durante el período de diferenciación y desarrollo embriológico del intestino primitivo. Objetivo: Presentar una malformación digestiva infrecuente en la edad adulta. Caso clínico: Paciente de 58 años que acude por dolor abdominal y aumento de volumen en hipogastrio. Al examen físico se palpa masa en hipogastrio de 15 cm de diámetro. La tomografía axial computarizada simple y contrastada mostró una masa tumoral en la excavación pélvica hipodensa con densidad de 18 UH, pared gruesa, de 2 cm, que realza con el contraste y agenesia renal derecha. El estudio anatomo-patológico informa quiste enterogénico. Discusión: La clínica de las duplicaciones intestinales es inespecífica, el dolor abdominal recurrente y la presencia de masa abdominal, son frecuentes. El diagnóstico preoperatorio de las duplicaciones intestinales es infrecuente, depende de la disponibilidad de estudios de imagen y la sospecha clínica. Es infrecuente la asociación de quiste enterogénico y agenesia renal. Conclusión: Se presenta una paciente masculino con una masa pélvica de etiología dudosa y agenesia renal derecha, en el que se diagnosticó un quiste enterogénico. La asociación de quiste enterogénico y agenesia renal es una malformación rara en el adulto(AU)

Introduction: Enterogenic cysts are malformations produced during the period of differentiation and embryological development of the primitive intestine. Objective: To report an rare digestive malformation in adulthood. Clinical case report: A 58-year-old patient came for abdominal pain and increased volume in the hypogastrium. On physical examination, a 15-cm diameter mass was palpated in the hypogastrium. Simple and contrast computerized axial tomography showed a tumor mass in the hypodense pelvic excavation with a density of 18 HU, a thick wall of 2 cm, which was enhanced with contrast and right renal agenesis. The anatomo-pathological study reports an enterogenic cyst. Discussion: The symptoms of intestinal duplications are nonspecific, recurrent abdominal pain and the presence of an abdominal mass are frequent. The preoperative diagnosis of intestinal duplications is occasional, it depends on the availability of imaging studies and clinical suspicion. The association of enterogenic cyst and renal agenesis is uncommon. Conclusion: A male patient is reported, with a pelvic mass of doubtful etiology and right renal agenesis, in whom an enterogenic cyst was diagnosed. The association of enterogenic cyst and renal agenesis is a rare malformation in adults(AU)

A report of two infant cases operated for jejunal duplication cyst associated with malrotation and volvulus.

INTRODUCTION: Both Enteric duplication and intestinal malrotation are concerning causes for intestinal obstruction in the pediatric age group and they very rarely coexist in the same patient. PRESENTATION OF CASES: We present 2 cases of previously healthy children, the first is a 4-month-old infant and the second is a 1.5-year-old boy, both presented with recurrent attacks of bilious vomiting that proved to be due to acute midgut volvulus caused by an enteric duplication cyst associated with intestinal malrotation. DISCUSSION: Enteric duplication and intestinal malrotation are two of the concerning causes of billious vomiting in the pediatric age group. They could be encountered at any level of the alimentary tract from the tongue to the anus. The term malrotation refers to all abnormalities of intestinal position. The coincidence of intestinal malrotation and an enteric duplication cyst (EDC) is very rare and has been described only in a few case reports. CONCLUSION: The concomitance of EDC and intestinal malrotation is extremely rare and should be kept in mind in a child presenting with bilious vomiting especially in a child preoperatively diagnosed with a duplication cyst.
