[Postoperative wound infections in elective colorectal surgery].

BACKGROUND: Surgical wound infections still represent a significant problem in colorectal surgery. We wanted to investigate the frequency of postoperative wound infections in patients who had elective colorectal surgery at Lillehammer County Hospital. By reviewing relevant literature we also wanted to assess the evidence base for using antimicrobial prophylaxis in colorectal surgery, which regimens are to be preferred, and the probable reduction in wound infections. MATERIAL AND METHODS: 99 patients were followed up at 14 days after surgery; presence or absence of wound infection was noted. Samples for culture were obtained in all patients with suspected wound infection. Literature on the subject was studied focusing on systematic reviews. RESULTS: Eight out of 99 patients (8%) had wound infections. In a systematic review of 147 studies comparing different antibiotic regimens, the overall infection rate for patients receiving antibiotic prophylaxis was 11%. INTERPRETATION: The surgical wound infection rate was comparable with the results from relevant systematic reviews. The effect of antimicrobial prophylaxis is well documented. A combination of an anaerobic and an aerobic drug should be used, but no gold standard can be identified. Two adequate regimens have been investigated in controlled studies carried out in Norway.

[Percutaneous drainage of the gallbladder in acute cholecystitis].

Percutaneous cholecystostomy has replaced surgical treatment for acute cholecystitis in surgical high-risk and critically ill patients. We wished to assess the procedures performed at Lillehammer County Hospital. We report 32 drainages performed in the last three years. Clinical records and radiological reports were reviewed retrospectively. Technical problems and complications during and after the procedure were recorded. In spite of relatively few procedures per radiologist, all were initially successful. No serious complications related to the procedure were encountered. Dislocation of the catheter occurred in 5 out of 32 drainages. This corresponds well to earlier reports. We conclude that percutaneous cholecystostomy in acute cholecystitis is a safe procedure in this group of high-risk patients at our hospital.

[Postoperative tetanus after gangrenous ileus].

Tetanus has become an uncommon disease in developed countries. Tetanus is caused by exotoxins from the bacteria Clostridium tetani. This microbe, which is obligate anaerobe, is present in soil, and animal and human faeces. The condition usually appears after contamination of wounds. However, reports have been published of tetanus occurring after both acute and selective gastrointestinal surgery. We present a case of severe postoperative tetanus in a 57 year-old woman who underwent bowel resection after strangulation of the ileum. The patient was treated on an intensive care unit and was artificially ventilated for 64 days. Seven months later she had fully recovered. Clinical presentation, diagnosis, treatment, and complications are discussed in the report. The diagnosis of tetanus is made by clinical observation. Nowadays, lack of suspicion of this condition may cause delay in administering proper treatment. Women and older men are often inadequately immunized. Doctors should therefore examine the immunization status of these groups of patients regularly.

Complications during the introduction of laparoscopic cholecystectomy in Norway. A prospective multicentre study in seven hospitals.

OBJECTIVE: To assess the morbidity of laparoscopic cholecystectomy since its introduction in Norway in the Autumn of 1990. DESIGN: Postal collection of prospectively collected data. SETTING: Practices of 26 surgeons in 7 district and university hospitals. SUBJECTS: 527 patients who underwent laparoscopic cholecystectomy. INTERVENTIONS: 133 patients (25.5%) had endoscopic retrograde cholangiopancreatography before operation, and two had cholangiograms during operation; dissection was by electrocautery in 490 patients and by laser in 37. MAIN OUTCOME MEASURES: Morbidity, number converted to open operation, and number who required reoperation. RESULTS: There were no deaths and a total of 70 complications (13.3%), 8 of which were after laser dissection. There were 59 local complications (11.2%) and 11 general (2.1%); 12 patients (2.3%) required reoperation for bleeding (n = 5), biliary leak (n = 4), and incisional hernia (n = 3). One had a retained stone in the common duct. 42 were converted to open operation (8.0%), 11 because of complications (bleeding, n = 6; damage to the bile duct, n = 3; and bowel perforation, n = 2). Of the 28 patients with acute cholecystitis 5 (17.9%) had to be converted to open operations and 7 (25.0%) developed complications. 2 of these patients had bile duct injury. CONCLUSION: The morbidity during the introductory period of laparoscopic cholecystectomy in Norway is higher than that reported elsewhere, indicating that the risk of complications is increased during the learning period.

[Laparoscopic cholecystectomy. A new therapeutic possibility].

We present the technique of laparoscopic cholecystectomy in some detail. The method was adapted at our clinic in August 1990. Postoperative results are very promising so far. We have reason to believe that this procedure will result in fewer postoperative complications and a smoother postoperative course for the patients, enabling them to regain physical ability much earlier than after conventional biliary surgery.

[Treatment of rectal prolapse. Perineal rectosigmoidectomy using a suture machine].

More than 50 operations designed for the treatment of complete rectal prolapse have been reported. Perineal rectosigmoidectomy using autosuture devices was first described by Vermeulen et al in 1983. During the last two years we have used this technique at Gjøvik County Hospital. We believe it to be a good alternative in patients where a transabdominal approach is unsuitable. The method is described in detail and illustrated by figures.

Popliteal vessel injury.

Popliteal vessel injury still carries a high amputation rate despite the progresses which have been made in vascular surgery. Three patients with such injuries treated with vascular repair are reported and a review of the recent literature is given. Prognostic factors as early diagnosis, delay in treatment, associated injuries as fracture/dislocation and venous injury, soft tissue injuries, adequate vascular repair, and postoperative complications are discussed.
