- 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 and a purse-string suture and a Z-suture causing double invagination. The caecum was filled with methylene blue and obstructed by a balloon catheter introduced via a caecostomy. Pressure inside the obstructed caecum was measured through a channel opening at the tip of the catheter. The pressure was increased with 4 cm of water every 10 minutes. The maximal pressure reached before leakage of methylene blue from the caecal closure or a drop in pressure in the lumen, was seen to be significantly higher in the groups with invagination and double invagination of the caecal closure, respectively, when compared with those with simple ligation only. The experimental data suggest that the invagination is important for secure closure of the caecal wall.

Laparoscopy for nonpalpable testis in childhood : Is inguinal exploration necessary when vas and vessels are not seen?
- 1996

In: European Journal of Pediatric Surgery. - : Georg Thieme Verlag KG. - 0939-7248 .- 1439-359X. ; 6:1, s. 7-9

Journal article (peer-reviewed)abstract
- A case of bilateral nonpalpable testes is described. Ultrasonography showed no testis. Laparoscopy revealed no intraabdominal testis, vas or vessels. Human chorionic gonadotrophine test suggested the presence of testicular tissue Computed tomography showed a testis present in each inguinal canal. Inguinal exploration confirmed the finding. This case stresses the importance of careful interpretation of the laparoscopic findings together with other diagnostic methods in localizing testicular tissue in patients with nonpalpable testes.

Normal and pathological bowel sound patterns.
- 1986

Journal article (peer-reviewed)abstract
- 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 emergency laparotomy. Bowel sounds varied markedly in all individuals studied. The most striking finding in mechanical obstruction was the regular occurrence of clustered bowel sounds. These were defined as 3-10 regular sounds, occurring one every five seconds, preceded and followed by at least one minute of silence. The associated periods of quiescent motor activity may account for the unexpectedly reduced frequency and motility index after a meal in obstructed patients compared with normal subjects. The different bowel sound patterns occurred in the patient with subtotal mechanical obstruction before and after a meal respectively i.e. infrequent and low-amplitude bowel sounds and clustered bowel sounds. The technique is probably not more sensitive than radiological procedures, and the abnormalities that are detected by an auscultation of bowel sounds are not specific.

Postoperative acute appendicitis.
- 1984
-
In: Annales Chirurgiae et Gynaecologiae. - 0355-9521. ; 73:5, s. 277-280
-
Journal article (peer-reviewed)abstract
- Six patients who developed acute appendicitis after surgical operations (cholecystectomy, choledocholithotomy, sigmoid resection, osteosynthesis of a hip fracture, abdomino-perineal resection) are described. The symptoms, signs and the results of investigations leading to relaparotomy are summarized. Possible causes of acute appendicitis after operation or trauma (luminal obstruction, bacterial infection, ischaemic changes and thrombosis) are discussed. As prevention is not possible, successful management of postoperative acute appendicitis includes an awareness of the complication and prompt surgical intervention.

Relationship between the removal of the nonacute appendix and the menstrual cycle
- 1984

Journal article (peer-reviewed)abstract
- The present author has investigated the frequency with which normal appendices are found at appendectomy in different phases of the menstrual cycle. The study is based on 504 female patients, 15–45 years of age, who were perated on for suspected acute appendicitis during the period from 1976 to 1982. The results are shown in Tables 1 and 2. The frequency of acute appendicitis in the luteal phase of the menstrual.

Journal article (peer-reviewed)abstract
- 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 was more than twice the frequency of the disease in the remaining half of the menstrual cycle. Further, there was a significantly higher proportion of gangrenous, perforated and normal appendices removed from patients in the menstrual and follicular phases of the menstrual cycle. The diseases mimicking acute appendicitis are tabulated. From these results it can be concluded that the female sex hormones might play an important aetiological role in the development of acute appendicitis or influence the inflammatory process in the appendix.
