Patient: Male, 20Final Diagnosis: Rectosigmoid hypoganglionosisSymptoms: Severe abdominal pain • obstipation • vomiting • shortness of breath • palpitationsMedication: —Clinical Procedure: Hartmann’s procedureSpecialty: SurgeryObjective:Congenital defects/diseasesBackground:Intestinal hypoganglionosis is very rare and accounts for 3% to 5% of all classified congenital intestinal innervation disorders. Isolated hypoganglionosis of the colon is a particularly rare form of the disease, and differential diagnosis includes association with Hirschsprung’s disease and chronic intestinal pseudo-obstruction (CIPO) related to visceral myopathies. Most cases are diagnosed at an early age or in childhood with only a few cases reported in adults.Case Report:We report a case of isolated hypoganglionosis of the rectum and sigmoid presenting as an emergency with acute intestinal obstruction in a 20-year-old male patient. A history of chronic constipation was reported since childhood, but this condition had never been investigated. A preoperative CT scan showed a megasigmoid and megarectum. A Hartmann’s procedure was performed. The patient made a slow recovery and was discharged on the 12th postoperative day in good condition. Histology showed features consistent with isolated hypoganglionosis, and a full thickness rectal biopsies taken 2 months later confirmed the diagnosis.Conclusions:Isolated hypoganglionosis in an adult is very rare, and a high index of suspicion is warranted in young patients with a history of chronic constipation to avoid delayed presentation as an emergency.
Rare co-existance of disease or pathology Background:Colonic varices are rare entity that often results from portal vein hypertension and hepatic cirrhosis. In the absence of underlying pathology, they are termed "idiopathic colonic varices". They are usually an incidental finding; however, they can present with varying degrees of lower gastrointestinal bleeding. There is only one reported case in the literature of colonic varices with a concomitant colonic tumor; our patient is the second one with such a presentation. We report a case of this rare combination with the outcomes of the elected surgical management and review the literature. Case Report:A 24-year-old male was referred to our hospital with a 1-month history of colicky abdominal pain. His family history is remarkable of 2 relatives with colonic varices. A computed tomography scan of the abdomen and pelvis showed a hepatic flexure colonic mass. Colonoscopy revealed pancolonic varices. Biopsy from the lesion revealed adenocarcinoma. Options were discussed with the patient to undergo only a right hemicolectomy for his cancer or a total colectomy to include the colonic segment involved with varices, and he elected the first option, with no complications upon 1 year follow up. Conclusions:Idiopathic pan-colonic varices are rare pathology. Their presence with colonic tumor presents a dilemma as to whether a subtotal/total colectomy is needed on the premise that a limited resection may carry the risk of subsequent bleeding. In the literature, the only similar case to ours had brisk postoperative bleeding, while ours did not experience such a complication.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
