Background and aims: The incidence of achilles tendon (AT) ruptures is increasing. The aim of the present study was to evaluate annual incidence, aetiology, operative complications and direct hospital costs of AT ruptures.

Material and methods: A retrospective study of 93 consecutive patients operated on for AT rupture from January 1986 to December 1996 at Kuusankoski District Hospital (area with 92,500 inhabitants) was performed. During the observation period no patient with an AT rupture was treated conservatively.

Results: 95 AT ruptures were treated including one rerupture (1%) and one patient with two ruptures. There were 7 (7%) patients with an open AT rupture. The total annual incidence in the hospital area was 8.6 (+/- 4.3) and for closed AT ruptures 8.0 (+/- 3.8). The total incidence was 9.3 (+/- 4.6)/10(5) and for closed AT ruptures 8.6 (+/- 4.1)/10(5) inhabitants per year. Most of the injuries were sport related, the most frequent sport being volleyball. Patients operated for closed AT rupture had major surgical complications in 4.5% of the cases and the total complication rate was 11%. The average direct hospital costs per patient was USD 1375.

Conclusions: The incidence of AT ruptures is increasing in South-East Finland. The rate of major surgical complication was low (4.5%) and comparable with earlier studies.

Background and aims: The increasing incidence of reoperations in coronary surgery associated with higher perioperative risks is a challenge for refinement of the surgical methods. The aim of the work is to prove the feasibility and satisfactory intermediate results of minimally invasive axillary-coronary artery bypass reconstruction in redo coronary surgery in case the left internal mammary artery had already been harvested.

Material and methods: Three patients (six months, two and six years after primary coronary artery bypass grafting) admitted for redo coronary surgery because of a recurrence of angina and proven malfunction of the left internal mammary artery-left anterior descending coronary artery anastomosis. An axillary-coronary venous graft was performed via left anterior small thoracotomy (LAST) on a beating heart in all three cases.

Results: Excellent patency of the graft was noted on control angiography within 9 days after the procedure together with good clinical improvement in midterm follow-up.

Conclusion: Minimally invasive axillary-coronary artery bypass via LAST access in redo coronary surgery is a good alternative in cases where the left internal mammary artery cannot be used.

Background and aims: To evaluate early results of elective ileal pouch-anal operations in children under the age of fifteen as compared to adult patients operated during the same period by the same surgical team.

Material and methods: Eighty-two patients with ulcerative colitis underwent restorative proctocolectomy during a six-year period, 1991-1996. Twelve of them (16%) were under the age of 15 years. Peroperative and short term postoperative morbidity were compared between the two groups.

Results: Covering loop ileostomy was performed on one patient in the juvenile group and 5 (7%) in the adult group. There were no significant differences in postoperative complications between the two groups. Eight (11%) leakages occurred in the adult group as compared to none in the juveniles. The children had a higher incidence of unexplained postoperative fever (50% versus 21%). Seven adults (10%) but no children underwent re-operation for these early complications.

Conclusions: It would appear that a team of experienced gastroenterologic surgeons can operate children as well as adults for ulcerative colitis with comparable early results without additional morbidity.

Backgrounds and aims: There are no randomised trials comparing internal fixation and hemiarthroplasty for a displaced intracapsular femoral neck fracture in relation to mental state.

Material and methods: To establish what should be the treatment of first choice, a prospective randomised clinical study was performed on 60 demented patients with displaced intracapsular femoral neck fractures, comparing internal fixation (n = 31) with hemiarthroplasty (n = 29).

Results: There was no significant difference in the mortality rate of both groups. Hemiarthroplasty was associated with significantly more loss of blood and more wound complications. Reoperation for secondary displacement of the fracture after internal fixation occurred in four patients. Although not-statistically significant, failure of internal fixation seemed to be higher after an inadequate osteosynthesis.

Conclusion: Postoperative mortality is high and the chance of successful rehabilitation very small for both types of treatment in this group of patients. In our opinion, demented patients should not be treated with a major surgical procedure like hemiarthroplasty. Internal fixation should be considered the treatment of choice, because it is a smaller operation than prosthetic replacement, with less morbidity. If adequate reduction can not be achieved, a primary hemiarthroplasty should be performed.

Recent advances not only in diagnostic imaging examinations but also in surgical techniques of liver resection have extended the indication of liver resection for colorectal metastases, and accumulated experience has improved surgical outcome. Liver metastases develop in a quarter of patients with colorectal cancer, and of these 30 % are candidates for liver resection under the criteria that liver resection is indicated when all tumors can be removed technically with adequate normal parenchyma left, no extrahepatic metastases are detectable, and the patients is considered fit for surgery. As the 5 year survival rate ranges from 30 % and 40 %, liver resection benefits 9 % to 12 % of patients with liver metastases. Recurrence in the liver remnant after liver resection develops in 40% to 50 %, and repeat liver resection benefits those patients.

Background: Apoptosis may be involved in the mechanism of acinar cell injury in acute experimental pancreatitis.

Aim: This study was to investigate whether apoptosis also is involved in human acute pancreatitis.

Method: A needle biopsy pancreatic specimen was obtained from a patient with acute oedematous pancreatitis. The specimen was stained with In Situ Cell Death Detection Kit. Similar specimen from a patient undergoing pancreatoduodenectomy for bile duct cancer served as a control.

Results: Extended acinar cell apoptosis was found in the pancreatitis specimen. No single apoptotic cell was found in the control pancreas.

Conclusion: Apoptosis probably is involved not only in acute experimental pancreatitis but also in human acute oedematous pancreatitis. The induction and role of apoptosis in pancreatis is discussed based on literature.

Background and aims: Open reduction and internal fixation of an extensively swollen ankle may lead to wound closure problems, blistering, wound edge necrosis and infection. Accordingly, internal fixation should be accomplished either before or after the period of critical soft tissue swelling. The object of the study was to investigate if the timing of surgery had any influence upon soft tissue complications and hospital stay.

Patients and methods: The clinical course of the first 6 postoperative weeks of 84 closed ankle fractures treated by open reduction and internal fixation were reviewed. Seventeen patients were not operated on early due to lack of operative capacity and were thus operated on after 5 days or more. These patients were compared to the patients operated on within 8 hours (n = 67). The groups were comparable with respect to age, gender and fracture types.

Results: Despite a higher incidence of primary soft tissue injuries in the early group, the patients operated on delayed had a higher incidence of wound infections (17.6% vs. 3.0%) and hospital stay was prolonged with 12.4 days compared to early surgery. All wound infections were found in grossly displaced fractures despite adequate closed reduction immediately after arrival in the hospital.

Conclusions: Delayed surgery of closed ankle fractures increases the risk of soft tissue complications and prolongs hospital stay. Immediate surgery is particularly indicated in the severely displaced ankle fracture, and if not achievable, temporary reduction and immobilization is recommended.

Background and aims: Administration of protamine might cause serious complications especially in patients treated preoperatively with NPH insulin.

Material and methods: A case report.

Results and conclusion: Administration of protamine sulphate caused fatal anaphylactic reaction to a diabetic patient undergoing femoropopliteal by-pass surgery. Care should be taken when administering protamine to a patient treated preoperatively with NPH insulin and the possibility of an anaphylactid reaction to protamine have to be kept in mind.
