ABSTRACT
Currently, liver transplantation is the only option for patients with end-stage liver disease. In Brazil, the mortality rate on the waiting list is about 25%. Multiple strategies to expand the donor pool are being pursed, however, grafts from poisoned donors are rarely used. This report documents successful liver, kidney and heart transplantations from four female donors who suffered brain death by hypoxia despite cardiopulmonary resuscitation following Aldicarb exposure ([2-methyl-2-(methylthio)propionaldehyde O-(methylcarbamoyl)-oxime]). The success rate of 12 grafts from four donors poisoned by Aldicarb was 91% 6 months after transplantation. Poisoned patients are another pool of organ donors who at present are probably underused by transplantation services. More studies are necessary to confirm the safety for the recipients.

BACKGROUND: Laparoscopy has been proposed as a diagnostic and potentially therapeutic modality for penetrating diaphragmatic lacerations. The purpose of this study was to assess the technical feasibility and strength of various laparoscopic repairs of diaphragmatic injuries. METHODS: Swine underwent either open suture repair or laparoscopic repair by staple, suture, or patch technique of a 2-cm laceration to both the right and the left muscular or tendinous diaphragmatic leaflets. Six weeks after operation, diaphragms were harvested for either histologic analysis or bursting strength measurements. RESULTS: All methods of repair proved technically feasible. There was no significant difference in bursting strength measurements between treatment groups. Bursting was due to tissue failure either at or adjacent to the repair site. Histologic analysis confirmed healing of all specimens with the laparoscopic patch technique inciting less inflammation and greater fibroblastic proliferation than the other techniques. CONCLUSIONS: Laparoscopic repair of diaphragmatic lacerations can be accomplished using any of the currently available techniques. Laparoscopic stapling, suturing, or patch techniques all result in complete healing with a strong and durable repair. When selecting a particular technique, familiarity of the surgeon should be used as a guideline.
