[Antibiotic prevention in acute appendicitis].

Preoperative prophylaxis with metronidazole suppositorium to patients undergoing appendectomy was introduced in our department in 1981. One hundred consecutive patients who had an appendectomy in the period May to October 1988 were reviewed to assess the efficiency of the prophylaxis. Postoperative infections were found in seven cases, but none were serious or caused sequelae. The clinical results of this simple, low-cost practice are satisfying, and we therefore intend to continue using metronidazole suppositorium as prophylaxis before appendectomy.

Endoscopic treatment of colorectal carcinoma.

All malignant pedunculated polyps of the colon can be removed totally by colonoscopy alone. Resection of the colon is only necessary in those few instances where the cancer portion is poorly differentiated and where there are cancer cells in lymphatic or vascular channels. Malignant well differentiated sessile polyps are adequately managed by the endoscopic technique as well if the polypectomy is believed to have been complete and this can be confirmed by follow-up biopsies after 4-8 weeks. In these patients Laser therapy may also be of value. Endoscopic Laser therapy may be of value as a symptomatic treatment in patients with advanced malignant disease with obstruction or bleeding.

Routine double contrast barium enema and fiberoptic colonoscopy in the diagnosis of colorectal carcinoma.

The diagnostic efficacy of routine double-contrast barium enema and fiberoptic coloscopy for detection of cancer was retrospectively studied in 303 patients consecutively operated for colorectal adenocarcinoma in a 52-month period from January 1980. Double-contrast barium enema was performed in 180 patients with 184 carcinomas, 157 (85%) of which were revealed by this examination. The detection rate of carcinoma according to site was 89% between cecum and descending colon, 92% in sigmoid colon and 71% in rectum. Fiberoptic colonoscopy was done in 176 patients with 181 carcinomas, 163 (90%) of which were detected by the endoscopical examination. The detection rate of carcinoma according to site was 86% between cecum and descending colon, 90% in sigmoid colon and 95% in rectum. The two methods were equally effective in detecting carcinoma of the colon. Colonoscopy was superior to barium enema in detection of rectal carcinoma.

Complications of fiberoptic gastrointestinal endoscopy--five years' experience in a central hospital.

Complications in relation to fiberoptic gastrointestinal endoscopy were recorded prospectively during the five-year period 1980-1984. Diagnostic esophago-gastroduodenoscopy (EGD) had non-fatal complications in ten out of 7,314 procedures (0.14%) and three deaths (0.04%). Therapeutic EGD had non-fatal complications in eight out of 440 procedures (1.8%) and two deaths (0.5%). Diagnostic endoscopic retrograde cholangiopancreatography (ERCP) had non-fatal complications in 15 out of 1,930 procedures (0.8%) and one death (0.05%). Therapeutic ERCP had non-fatal complications in 14 out of 554 procedures (2.5%) and six deaths (1.1%). Diagnostic colonoscopy had non-fatal complications in five out of 3,538 procedures (0.14%) and therapeutic colonoscopy in 21 out of 1,055 procedures (2.0%). There were no deaths in connection with diagnostic or therapeutic colonoscopy. The recommendations based on this series are: Put greater emphasis on a proper evaluation of indications and contraindications. Avoid sedation of patients with respiratory failure. If possible, postpone procedures which may cause bleeding in patients with impaired hemostasis until proper correction has been achieved.

Laparoscopy in patients admitted for acute abdominal pain.

In 81 patients with acute abdominal pain, laparoscopy was performed because of diagnostic doubt. Diagnosis by clinical methods proved to be correct in 42 of the patients and laparoscopy gave correct diagnosis in 70. Appendectomy revealed acute appendicitis in 19 patients and normal appendix in five. Failure to establish a diagnosis by laparoscopy was due to incomplete visualization of appendix in nine patients, pelvic adhesions in one patient, and failure to enter the peritoneal cavity in another. A clinical diagnosis of acute appendicitis could be invalidated by laparoscopy in 17 of 40 patients. Negative laparotomy is potentially avoidable by use of laparoscopy when a diagnosis of appendicitis is questionable. Laparoscopy may therefore be warrantable in such cases.

Simultaneous urethrocystometry in gynaecological patients with lower urinary tract dysfunction.

Simultaneous urethrocystometry was used in the investigation of 103 gynaecological patients with complaints of lower urinary tract dysfunction. The symptom of stress incontinence was present in 71 patients, and was verified in 56. The symptom of urge incontinence was present in 46 patients, urgency in 15 and other symptoms in 22. Motor urge incontinence was revealed in 13 patients, sensory urge incontinence in 3 and unstable urethral pressure in 30. A carefully recorded case history should be supplemented with objective measurements to obtain a correct diagnosis.

Termination of early first trimester pregnancy with 16,16-dimethyl trans delta 2 prostaglandin E1 methyl ester.

Thirty healthy women with early first trimester pregnancy applying for legal abortion were given five vagitories containing 1 mg 16,16-dimethyl-trans delta 2 prostaglandin E1 (16,16-dimethyl PGE1). They were instructed to take one vagitory every third hour. The treatment was evaluated at follow-up visits after one, two and four weeks. Complete abortion was recorded in 27 cases. The pregnancy test was still positive after two weeks in three women, who underwent surgical termination, and were recorded as failures. The most common side-effects were bleeding, pain and gastrointestinal symptoms. No serious side-effects were recorded. Repeated administration of vagitories containing 1 mg 16,16-dimethyl PGE1 seems to be a safe and effective method of "menstrual extraction". The efficacy should be increased and the rate and intensity of side effects decreased if "menstrual extraction" is to compete with conventional dilatation and curettage.

Evaluation of threatened abortion by human chorionic gonadotropin levels and ultrasonography.

To determine the prognostic value of human chorionic gonadotropin (HCG) concentrations in maternal plasma and urine, we studied 104 women with threatened abortion (cases) and 108 women with normal pregnancies and normal serum levels of HCG (controls). Of the 104 cases, 48 were also examined ultrasonically. We concluded that measurements of serum levels of HCG are of more accurate prognostic value than those of urine levels. Low serum levels of HCG indicate a poor prognosis for the pregnancy, as do steady decreases, in repeated measurements, of initially high HCG level. The combination of normal serum levels of HCG and signs of fetal life during ultrasonic examination indicates a very good prognosis for the pregnancy.

Selection criteria for endoscopic retrograde cholangiopancreaticography (ERCP) in patients with gallstone disease.

Endoscopic retrograde cholangiopancreatography (ERCP) has been used in patients referred to cholecystectomy when clinical information, biochemical values, or ultrasonography (clinical characterization) have indicated possible presence of common bile duct stones. A retrospective study of 599 patients treated for gallstone disease was used to develop a characterization procedure for predicting common bile duct stones by a discriminant analysis procedure. The variables selected by the analysis as the best combination for CBDS prediction were age (years), the values of bilirubin (micromol/l), ALAT (U/l) and gamma GT (U/l). The characterization was false positive in 22 cases (3.7%) and false negative in 11 cases (1.8%), compared to 198 false positive cases (33.1%) and three false negative cases (0.5%) by the clinical characterization. A leaving-one-out correction did not change the results. In a test set of 157 cholecystectomy patients, clinical characterization was false positive in 44.6% of the patients, compared to 4.5% false positive results when using the discriminant analysis procedure. The discriminant analysis procedure would have missed one patient with common bile duct stones. Selection by the discriminant analysis characterization procedure seems to reduce the frequency of preoperative ERCP significantly without an increase in undetected common bile duct stones.
