Chronic radiation proctitis is a disease associated with radiotherapy of cancer in the pelvic region. The main symptom is rectal bleeding. Several treatment modalities have been attempted, but few have demonstrated satisfactory effects. We present our experience with formalin applied locally to the rectal mucosa in the treatment of chronic radiation proctitis. Furthermore, we assess possible complications, the gravest suggested being cancer. Previous studies on the subject have reported good results, but often with a somewhat vaguely defined follow-up. Our evaluation of the treatment was based on both subjective symptoms and proctoscopic findings. ⋯ The formalin treatment had a very good effect on chronic radiation proctitis. Possible complications were detected. Except in the case of anorectal pain, these are all of a questionable nature and can possibly be attributed to chronic radiation proctitis itself rather than the formalin treatment. Further study is warranted to confirm long-term effects of the formalin and to exclude possible complications, especially secondary anorectal cancer.

The insertion of prophylactic ureteral stents in traditional colorectal surgery has been debated for a long time. The aim of this study is to investigate the results of ureteric stent insertion in elective laparoscopic colorectal surgery in terms of complications and costs. ⋯ The prophylactic use of a ureteral stent in laparoscopic colorectal surgery leads to minor complications and may be cost-effective.

Surgery cancelations cause inappropriate use of hospital resources and additional financial and psychological stress to patients. Cancelation rates have been described to be even more than 10% of scheduled cases. Preoperative anesthesia evaluation clinics have been initialized to decrease cancelation rates. At Hyvinkää hospital, 95% of elective surgical patients are admitted on the morning of operation, and only 25% of these patients visit preoperative anesthesia evaluation clinic prior to surgery. Cancelation rate in Finnish hospitals has not been described. ⋯ Day of surgery cancelation rate was low in same-day admission, although it varied between specialties. Specialties having explicit surgery indications had fewer cancelations than specialties having surgery indications based on more subjective diagnostic. Process improvements need to be considered continuously to further decrease cancelation rate.

Aging with comorbidities, obesity, and rapid recovery from operation may increase the need for laparoscopic cholecystectomy, but long-term use of statins may be associated with a decreased risk of gallstones. This population-based cohort study presents the changing rate and causative factors of laparoscopic cholecystectomy in Finland during the era of statin use. ⋯ The rates of all cholecystectomies decreased despite marked increase in laparoscopic cholecystectomies performed. The increase in risk factors for gallstones in Finland implied more marked increase in laparoscopic cholecystectomies. The possible role of statins on gallstone disease is discussed.

The mastery of manual skills that are indispensable for the performance of surgical tasks is a competence specific to surgery. One way of facilitating this acquisition is to move the training out of the operating room and all of its restrictions. Surgical training out of the operating room, also called simulation, has spread widely in the past decade, especially in laparoscopic and endoscopic surgery. ⋯ There is a wealth of simulators, ranging from low- to high-fidelity simulators incorporating haptic feedback. They comprise basic tasks, procedural modules, and full procedures. Virtual reality simulators have shown acceptable fidelity and validity evidence. Moreover, training out of the operating room on virtual reality simulators has demonstrated its positive impact on basic skills during real laparoscopic procedures in patients. The benefit of virtual reality over simple video trainers remains unclear for teaching basic skills. However, virtual reality simulators provide automatic feedback that permitted to design structured competency-based curricula and allow deliberate practice. Finally, advanced procedures and patient-specific models have been designed on virtual reality simulators, and further investigations are still awaited to appraise their educational value.
