Primary Outcome of Laparoscopic Colorectal Resections in a Northern Finnish Hospital: A Single Center Study.

BACKGROUND AND AIMS: Over the past decades, laparoscopic colorectal surgery has become widely used for various indications. Large multicenter studies have demonstrated that laparoscopy has clear advantages over open surgery. Compared to open procedures, laparoscopy decreases perioperative blood loss, post-operative pain, and hospitalization time, but provides equivalent long-term oncological and surgical results. Most studies have been conducted in high-volume institutions with selected patients, which may have influenced the reported outcome of laparoscopy. Here, we investigated the primary outcome of all laparoscopic colorectal resections performed between 2005 and 2015 in a low-volume center. MATERIALS AND METHODS: This retrospective study included bowel resections performed between 2005 and 2015 in the Lapland Central Hospital. Data were retrieved from electronic patient registries, and all operations that began as a laparoscopy were included. Patient records were investigated to determine the primary surgical outcome and possible complications within the first 30 days after surgery. RESULTS: During 2005-2015, 385 laparoscopic colorectal resections were performed. Indications included benign (n = 166 patients, 43.1%) and malignant lesions (n = 219 cases, 56.9%). The median patient age was 68 years, and 50.4% were male. The median American Society of Anesthesiologist score was III, and 48.5% of patients had an American Society of Anesthesiologist class of III or IV. The median hospital stay after surgery was 6 days (interquartile range: 3.8). The conversion rate to open surgery rate was 13%. The total surgical complication rate was 24.2%, and re-operation was required in 11.2% of patients. A total of 26 patients had anastomotic leakage, of which 16 required re-operations. The 30-day mortality was 0.8%. CONCLUSION: Our results showed that laparoscopic colorectal surgery in a peripheral hospital resulted in primary outcome rates within the range of those reported in previous multicenter trials. Therefore, the routine use of laparoscopic colorectal resections with high-quality outcome is feasible in small and peripheral surgical units.

High-frequency hearing of dental personnel.

234 dentists and dental nurses were examined with a normal and a high-frequency audiometer in high standard clinical conditions. Their ordinary and high-frequency hearing as compared with the controls showed no significant differences. Thus, exposure to high-frequency noise from high-speed drills and other modern dental instrumentation does not appear to be harmful to one's hearing and does not necessitate audiologic screening procedures for dental personnel.
