Obstruction of the appendix lumen in relation to pathogenesis of acute appendicitis

The role of obstruction in the pathogenesis of acute appendicitis was studied by measuring the pressure in the appendix peroperatively in 33 patients undergoing appendectomy because of suspected acute appendicitis. The technique involved insertion of a fine needle via the apex into the lumen of the appendix and measurement of the hydrostatic pressure required to inject a saline solution. In all si

Scoring system for computer-aided diagnosis of acute appendicitis. The value of prospective versus retrospective studies

The high negative exploration rate in patients with suspected acute appendicitis is the main compelling reason to improve the accuracy in managing patients with acute abdominal pain. In this article, data from a prospective study on a group of patients undergoing acute appendectomy were used to devise a scoring system for the purpose of differentiating between the patients with an acute appendicit

Acute appendicitis risk in various phases of the menstrual cycle

The significantly different age-specific incidence of acute appendicitis between males and females in the second, third and fourth decades of life led to a study of the frequency of acute appendicitis and the degree of appendiceal inflammation found at operation in the different phases of the menstrual cycle. The frequency of acute appendicitis was almost twice as high in the luteal phase as in th

Appendicectomy in the elderly, incidence and operative findings.

The incidence during the last decades of acute appendicitis and the number of appendicectomies in the elderly, 60 years of age and older were studied. In addition, the incidence of the disease and of appendicectomy and the preoperative findings were studied in a well defined population during the twelve year period from 1969 to 1980. The results showed that there was no increase in the sex- and ag

Relationship between the removal of the nonacute appendix and the menstrual cycle.

The significantly higher incidence of removal of a normal appendix in females in the second, third and fourth decades of life for suspected acute appendicitis lead to a study of the frequency of appendicectomy and the peroperative findings at the time of surgery in patients in different phases of the menstrual cycle. The results showed that the frequency of acute appendicitis in the luteal phase w

Varying frequency of acute appendicitis in different phases of the menstrual cycle

From the results of this study, it can be concluded that a difference is noted in the frequency of acute appendicitis and the number of appendectomies performed in different phases of the menstrual cycle. Therefore, the female sex hormones might play an important role in the cause of acute appendicitis. This is further supported by the lower sex specific incidence of acute appendicitis for women i

A neuromuscular basis for the development of right inguinal hernia after appendectomy

Abdominal muscular contractions may have a protective influence against the development of indirect inguinal hernia. A portion of the transversus abdominus muscles acts on the internal inguinal rings and produces a closure mechanism during voluntary abdominal muscular activity. It follows, therefore, that injury or inactivation of this mechanism may be an etiologic factor in the development of ind

Development of right inguinal hernia after appendectomy

The incidence of right inguinal hernia is significantly greater in patients who have undergone appendectomy than in the general population. The most likely cause of such hernias is injury to the segmental nerve supply to the inguinal musculature. The choice of incision at appendectomy may therefore be important, and the surgeon should avoid injury to the nerve branches and important structures in

Acute appendicitis as a sign of a colorectal carcinoma

The relationship of acute appendicitis occurring previous to cancer in colon and rectum was studied in the consecutive records of 561 patients, of 40 years of age and older, operated upon with an appendectomy because of acute appendicitis. Sixteen (2.9%) of these patients were readmitted within three years because of a carcinoma in colon or rectum. The incidence of carcinoma in the colon and rectu

Decreasing incidence of acute appendicitis, with special reference to the consumption of dietary fiber

The incidence of acute appendicitis and the total number of appendectomies performed in the adult population admitted to our medical center are both decreasing. The cause is not clear. Better nutrition and the wide-spread use of antibiotics are two possible factors which come to mind, but we know of no scientific evidence that these are responsible. There has been a slight decrease in the mean die

Ultrasonic Diagnosis of Testicular Torsion

An ultrasonic technique to avoid errors in the diagnoses of acute testicular torsion is described. The presence or absence of intratesticular arterial pulsation was recorded and analysed. The technique may reduce diagnostic failures and the number of scrotal explorations of nontorquered testis.

Treatment of malignant melanoma with dacarbazin (DTIC‐DOME) with special reference to urinary excretion of 5‐S‐cysteinyldopa

Seventeen patients were given DTIC, 200 mg/m2/day in five‐day courses every four to six weeks. In four patients (stage II) treated on an adjuvant basis, tumor recurrence has been verified in three. Four of the palliatively treated patients were also given DTIC by regional intra‐arterial infusion with minimal positive tumor effect and minimal toxicity. 5‐S‐cysteinyldopa excretion in urine was check

The role of auscultation and registration of bowel sounds in the diagnosis of acute appendicitis.

The study described was designed to evaluate the role of auscultation and registration of bowel sounds in the diagnosis of acute appendicitis. In 37 patients with suspected acute appendicitis undergoing appendicectomy the bowel sounds were registered twice pre-operatively and once on the postoperative day. The results show that single registration of bowel sounds is rarely diagnostic, but repeated

Acute appendicitis related to faecal stasis

The objectives of the study presented here were to evaluate the role of faecal stasis in the development of acute appendicitis. Inquiries about bowel habits were made of 188 patients admitted to this Department of Surgery with a clinical diagnosis of acute appendicitis, and of 188 healthy volunteers without known gastrointestinal disease, matched for age and sex. The results show that the number o

The level of copper, zinc and certain free amino acids in the plasma of patients with acute appendicitis

Many forms of inflammatory conditions are associated with alterations in physiology, metabolism and concentrations of trace elements such as copper, magnesium, zinc and calcium and of amino acid patterns and C-Reactive protein levels in plasma (1). Decreased levels of zinc and a reciprocal increase of copper in plasma has been seen in many human diseases (2). Nothing concrete is documented concern

Invagination versus simple ligation of the caecal tip with reference to the strength of the caecal closure. An experimental study in the rat.

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

Effect of loperamide on faecal control after rectoplasty for high imperforate anus

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

Normal and pathological bowel sound patterns.

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
