Although several surgical approaches have been advocated for patients with infected necrotizing pancreatitis, there is still a high incidence of morbidity and mortality. We used a new approach of direct retroperitoneal open drainage after various other treatments, for three patients with necrotizing pancreatitis and extended infection with multiple-organ failure. Long oblique incisions were made from the root of the 12th rib to the anterior superior spina iliaca on the left or right side of the back, or both, to approach the retroperitoneal area of infected necrosis. The necrotic tissue was removed bluntly and the wound was laid open. Lavage and debridement were done repeatedly after the operation. The patients recovered from multiple-organ failure within 2 weeks, and control of local infection was achieved within 3-4 weeks. All three patients were discharged and are now well. Therefore, we propose that this method is appropriate for patients with spreading infected necroses, who are in poor general condition.
PURPOSE: To survey active vitreoretinal surgeons to determine how often they intentionally debride the corneal epithelium during vitrectomy surgery for diabetic patients and to ascertain whether the selection of the surgical lens type influences the debridement rate. DESIGN: Observational retrospective case series. METHODS: Fifty-five vitreoretinal surgeons were asked to retrospectively report how many pars plana vitrectomies they performed in 1 year on diabetic eyes and in what percent of the cases was debridement of the cornea necessary. In a second query, they were asked to note which specific type of surgical lens system (hand-held irrigating, Landers sew-on, or Oculus BIOM noncontact) was used for their surgical intervention. RESULTS: The total number of diabetic vitrectomies performed in 1 year by the respondents was 8,002. The frequency of epithelial debridement was 17.4%, with a range of 0% to 90%. The use of irrigating contact lenses was associated with a significantly higher rate of debridement compared with the use of sew-on or BIOM noncontact lenses (23.5% vs 12.1%, P <.001). Regarding the 41 surgeons who indicated a specific type of lens used, we found that the debridement rate for infusion lenses was 23.8% compared with 13.0% for sew-on lenses and 15.6% for noncontact BIOM lenses. The difference between these groups was statistically significant (P <.025). CONCLUSIONS: Irrigating contact lenses appear to increase the need for epithelial debridement compared with other alternatives. Sew-on lenses with a viscoelastic cushion may provide the best corneal protection.
We describe a technique for the accurate and conservative debridement of the ends of divided flexor tendons. We have found this technique particularly useful for the secondary repair of tendons after re-rupture.
