In an experimental model using the rat, the role of invagination and double invagination for efficient closure of the caecum was studied. A standardized opening of the tip of the caecum was closed in three different ways, thus placing the animals in three groups. I: Closed with simple ligation. II: Closed with simple ligation and a purse-string suture invagination. III: Closed with simple ligation
The effect of loperamide on faecal control after Stephens rectoplasty for high imperforate anus was studied in eight patients more than 8 years after surgery. Clinical assessment and anorectal manometry were performed before and after administration of loperamide for 6 to 8 weeks. Decreased faecal soiling was noted in seven of the eight cases. Obstipation forced two patients to stop the medication
The purpose of this study was to determine the usefulness of auscultation of bowel sounds in evaluating patients with total and subtotal small intestinal obstruction and immediately after operation. The study was based on ten healthy volunteers, seven patients with documented mechanical obstruction, one patient with chronic subtotal mechanical obstruction and twelve patients undergoing an emergenc
The purpose of this study was to compare the suture of a microvascular anastomosis with and without the aid of sodium hyaluronate. The divided femoral arteries of ten Sprague‐Dawley rats were sutured using sodium hyaluronate on one side. Operating time, bleeding, and patency rates were studied and compared. No significant differences were found in the measured parameters. However, the clinical imp
Environmental or genetic factors are sought to explain the high incidence of thyroid cancer in Iceland. At present, it is impossible to cite any environmental factor, particularly one related to the volcanic activity in the country, which could explain the high incidence of thyroid cancer in Iceland. However, the thyroid gland in Icelanders is very small due to the high intake of iodine from seafo
A simple and reproducible model for the experimental study of the normally functioning human appendix is described. The appendix removed from a human is transplanted into a nude mouse and is kept vital for at least 4 hours. This model is an improvement on previous models. It corresponds well with the working of the normal human appendix as regards tissue type and characteristics. Results are easil
In an experimental model using the human appendix transplanted into the Rowett rat, the role of obstruction in the pathogenesis of acute appendicitis was studied. Nine animals were anaesthetized and underwent laparotomy. Normal human appendices, removed during routine surgery, were transplanted into the rats. The appendices were obstructed by a balloon catheter introduced through the open end. Pre
Between 1969 and 1984 65 children were operated on for testicular torsion. A follow-up study of 63 patients who underwent surgery for unilateral testicular torsion with fixation only on the affected side showed that no torsion occurred on the opposite nonfixated side and there was no retorsion during an observation period of an average of more than seven years. From our calculated risk for contral
The value of bacteriologic findings in patients with acute appendicitis was studied. Routine urinary culture specimens were taken preoperatively from 194 children (mean age 11±3 years) undergoing emergency appendectomy. Bacteria were found in culture specimens of urine from 26 of 156 patients with acute appendicitis. The bacteriuria was correlated to the position of the appendix, the duration of d
A follow-up study of 12 patients who had undergone Stephens rectoplasty for high imperforate anus is presented. Clinical assessment and anal electromyography were performed more than 7 years after surgery, both before and after a year's physiotherapeutic training of the perianal musculature. Electromyography showed correlation between faecal continence and tonus of the anal sphincter, the anocutan
At present our knowledge of enteric peptide-containing neurons in man is limited. In this study we have used human appendices removed at surgery to examine the peptidergic innervation by immunocytochemistry, immunochemistry, and pharmacological in vitro experiments. Immunocytochemistry revealed a variety of peptide-containing nerve fiber populations in the human appendix. VIP/PHI-, VIP/PHI/NPY-, S
Computed tomography (CT) was performed in 9 patients with faecal incontinence more than 8 years after rectoplasty for high imperforate anus. The radiologic findings were correlated with the clinical evaluation of faecal incontinence. No statistically significant correlation was found between function and anatomic findings as demonstrated by CT. Thus, although CT demonstrates the post-operative ana
Computerised tomography and magnetic resonance tomography were performed in nine faecally incontinent patients more than eight years after rectoplasty for high imperforate anus. No statistically significant correlation was found between function, i. e. degree of faecal incontinence, and anatomical findings. Thus, in spite of a detailed demonstration of the post-operative anatomy, the information d
This paper reports on two cases of incarcerated congenital diaphragmatic hernia presenting as intestinal obstruction without any signs or symptoms or respiratory tract illness.
Open testicular wedge biopsy has electively been performed prior to completion of maintenance therapy for acute lymphoblastic leukemia. 25 boys during 6 years were included in this prospective study. Three boys developed testicular enlargement while on maintenance therapy and biopsies confirmed testicular leukemia. The remaining 22 boys were biopsied at termination of maintenance therapy. Occult t
