Trauma in cirrhotics: survival and hospital sequelae in patients requiring abdominal exploration.

Hepatic cirrhosis significantly increases the mortality and morbidity of elective surgery; therefore we hypothesized that cirrhosis would adversely impact outcome after abdominal trauma. We used the trauma registry to identify 17 patients with cirrhosis who sustained trauma injuries requiring emergent exploratory laparotomy. Patients were characterized with respect to age, sex, hospital days, intensive care unit days, and trauma scores. A control group (n = 73) was constructed from the registry by matching age, sex, Injury Severity Score (ISS) and Abbreviated Injury score. Mortality rates were compared by Fisher's exact test and age, ISS, Revised Trauma Score 2, and hospital and intensive care unit days were compared by Student's t test. Despite similar ISS between cirrhotic patients and controls, patients with cirrhosis had a fourfold increase in mortality (mortality odds ratio = 7.2; 95% confidence interval = 2.2-24.0). Cirrhotic trauma patients had a complication rate of 71 per cent and a mortality of 44 per cent. We conclude that cirrhosis is a major independent risk factor for mortality in trauma patients with injuries that require emergent abdominal surgery.

Initial experience with laparoscopic live donor nephrectomy.

BACKGROUND: Advances in laparoscopic instruments and video technology have made laparoscopic donor nephrectomy (LDN) feasible. We report our initial experience with this technique. METHODS: A retrospective review of 30 open donor nephrectomies and our first 30 LDNs was performed to assess donor and recipient outcome and resource usage. RESULTS: LDN was successfully completed in 26 donors (87%). The increased operative time and costs were balanced by less postoperative pain, earlier discharge, earlier return to normal activity and work, fewer incision problems, and less personal financial loss. Recipient outcome was not affected. CONCLUSION: LDN is technically feasible and safe, and recipient graft outcomes are equivalent. Convalescence is shortened, and there is less personal financial loss. LDN offers significant benefit to the donor and may result in increased organ donation.

Civilian rectal trauma: a changing perspective.

BACKGROUND: Recently the Organ Injury Scaling Committee of the American Association for the Surgery of Trauma developed a Rectal Injury Scaling System (RISS). Little data exist regarding its clinical utility. METHODS: We retrospectively reviewed 45 patients with rectal injuries to assess the impact of the RISS on patient management and outcome. We compared RISS grade I patients (group I, partial-thickness injury) with patients with grades 2, 3, and 4 injuries (group II, full-thickness injury). RESULTS: Group II underwent distal rectal washout and repair of the injury twice as often and had a significantly higher rate of diversion of the fecal stream. This was associated with a 3-fold increase in complications. The only complications in group I were in patients managed with diversion of the fecal stream and distal rectal washout. CONCLUSIONS: Our data suggest that aggressive surgical management for RISS grade I injury may not be necessary. Implementation of therapy based on the RISS may improve outcomes of civilian rectal trauma.

Surgical technique/post-transplant surgical complications.

Renal transplantation has become a common form of therapy for the patient with end-stage renal disease. The operative procedure has been refined and is discussed. Fortunately, surgical complications requiring therapy are unusual. An overview of the surgical complications, including etiology and therapeutic options, is presented.

Attitudes and beliefs concerning organ donation among Native Americans in the upper Midwest.

Because of increasing access to renal replacement therapy and the high incidence of renal disease among Native Americans largely due to type 2 diabetes mellitus, it is important to determine attitudes and beliefs in this population toward organ donation. In a study conducted on reservations in the upper Midwest during traditional powwows and health fairs, it was discovered that willingness to donate was more likely to occur if Native Americans were approached by a healthcare worker from their culture, if they had already signed a donor card, or if they knew someone with diabetes. Willingness to be a living donor (81%) was greater than willingness to donate after death (i.e., as a cadaveric donor) (54%). These findings indicate that cultural-specific information about organ failure rates and organ donation, when presented by knowledgeable individuals within the culture, could increase donation in the Native American population.

A randomized trial comparing cyclosporine induction with sequential therapy in renal transplant recipients.

Calcium antagonists may reduce the nephrotoxicity of cyclosporine (CsA), allowing CsA to be introduced immediately after renal transplantation and thereby obviating the need for sequential induction therapy with a monoclonal or polyclonal antibody. To test this hypothesis, in a pilot feasibility trial 100 cadaveric or one-haplotype-mismatched living-related renal transplant recipients were randomized to either (1) sequential therapy with anti-thymocyte globulin (ATG) (ATGAM; Upjohn, Kalamazoo, MI) 20 mg/kg/d for 7 to 14 days until renal function was established and CsA (Sandimmune; Sandoz, East Hanover, NJ) was started, or (2) CsA 8 mg/kg/d begun immediately before surgery with diltiazem (Cardizem; Marion Merrell Dow, Kansas City, MO) 60 mg sustained release twice daily. Acute rejection episodes during the first 90 days were not different with ATG versus CsA induction (42% v 28%; P = 0.142 by chi-square analysis). Graft failures (10% v 16%; P = 0.372) and the incidence of delayed graft function (28% v 34%; P = 0.516) were also similar with ATG compared with CsA. ATG caused lower platelet counts (138 +/- 59 x 10(3) v 197 +/- 75 x 10(3) at 7 days; P < 0.001) and lower white blood cell counts (9.6 +/- 4.6 x 10(3) v 12.3 +/- 4.9 x 10(3) at 7 days; P = 0.003). Diltiazem reduced the dose of CsA required to maintain target blood levels (479 +/- 189 mg/d v 576 +/- 178 mg/d at 14 days; P = 0.015). There were no statistically significant differences between the groups in serum creatinine levels at days 1, 3, 5, 7, 14, 28, 60, or 90. The results of this pilot feasibility trial suggest that prophylactic treatment with CsA and diltiazem may be equally effective and less toxic than ATG induction after renal transplantation.

Clinical impact of replacing Minnesota antilymphocyte globulin with ATGAM.

In August 1992, we replaced Minnesota antilymphocyte globulin (MALG) with lymphocyte immune globulin, antithymocyte globulin (equine) (ATGAM) in our immunosuppression protocols. The clinical impression of increased graft rejection prompted our assessment of the effect of this change on patient and graft outcome. The initial study group consisted of 426 renal transplant recipients transplanted between October 1, 1987, and September 21, 1993. After exclusions, 388 transplant events, with a minimum 8-month follow-up, made up the final study cohort: 323 patients received MALG and 65 received ATGAM. Immunosuppression included intravenous methylprednisolone, oral prednisone, oral AZA, CsA in some cases, and intravenous MALG or ATGAM, 15 mg/kg/day, for 7 to 14 days. Acute rejection was treated with high dose intravenous steroids and steroid-resistant episodes were treated additionally with either MALG or OKT3. Statistical comparisons were stratified for multiple patient characteristics and treatment variations. There was a greater incidence of rejection in general, and a higher incidence of steroid-resistant episodes requiring subsequent antilymphocyte globulin therapy (P = 0.0073) in patients receiving ATGAM versus MALG. No difference was seen in the incidence of CMV infection or blood-borne sepsis. Lymphoma occurred in 3 MALG and 2 ATGAM recipients. MALG recipients were significantly less likely to experience rejection within the first 60 days after transplant (P = 0.0127 using unstratified data; P < 0.0001 when data were stratified for patient characteristics). The relative risk of acute rejection for posttransplant days 5, 7, 10, and 14 was consistently higher for ATGAM-treated patients. We conclude that MALG and ATGAM are not equivalent drugs, and that MALG is a more effective immunosuppressant, and is just as safe as ATGAM in our protocol environment.

Management of dialysis-associated steal syndrome complicating upper extremity arteriovenous fistulas: use of intraoperative digital photoplethysmography.

Dialysis-associated steal syndrome (DASS) occurring after creation of arteriovenous fistulas often necessitates ligation of the fistula. From June 1987 to June 1990, a total of 542 upper extremity arteriovenous fistulas were constructed: radiocephalic fistulas in 182 patients, 325 forearm loop grafts and 32 upper arm loop grafts. We managed 27 patients with DASS including two patients who were referred from other hospitals. DASS developed in two patients (1%) with radiocephalic fistulas and in 23 patients (6.4%) with arteriovenous grafts. Of the 27 patients, the fistula was ligated in nine because of tissue loss, severity of symptoms, or absence of improvement in digital pressure with the fistula occluded. Intraoperative digital photoplethysmography was used to guide the amount of graft narrowing in 16 patients. The goal was to obtain a digital blood pressure of 50 mm Hg or digital to brachial ratio of more than 0.6. Ten of the 16 patients had satisfactory graft function for more than 6 months, and all patients had improvement or resolution of the steal syndrome. We conclude that DASS is an uncommon complication of upper extremity arteriovenous shunts and narrowing of the fistula and that using intraoperative digital photoplethysmography as a guide is a useful method for relieving the steal syndrome and salvaging the shunt.

Combined orthopedic and vascular injury in the lower extremities: indications for amputation.

A retrospective review was undertaken to determine risk factors associated with amputation after open fractures of the lower extremity that were complicated by vascular injury. During an 11-year period ending in December 1987, we observed open fractures in 31 patients and injuries to the popliteal artery in 16 patients, to the tibial arteries in eight patients, to the femoral artery in five patients, and to the dorsal artery of the foot in two patients. Vascular repair was accomplished in 25 patients; 12 patients had primary end-to-end anastomosis, 12 patients had reverse saphenous vein grafts, and one patient had a bovine graft. Of these 25 patients, five patients required amputation because of infection and three patients required amputation because of continued ischemia. Three patients with irreparable damage had immediate amputation, and three patients without distal ischemia had vessel ligation only. The risk factors associated with amputation were shock on admission (10 of 19 patients [p less than 0.02]) and a crushed extremity (10 of 18 patients [p less than 0.01]). The overall amputation rate, which included three immediate amputations and eight late amputations, was 35.2%. The data suggest that limb salvage is possible in two thirds of patients with combined orthopedic and vascular injuries of the lower extremity, but a history of shock or crush injury with vascular compromise is an unfavorable prognostic sign.

Experience with colonic volvulus.

Fifty-eight cases of colonic volvulus were reviewed including 30 cases of sigmoid volvulus, 27 cases of cecal volvulus, and 1 of transverse colon volvulus. Decompression procedures were attempted in 31 instances of sigmoid volvulus in 27 patients and were successful 25 times (81 percent). Seven patients with sigmoid volvulus did not undergo surgery and of those, two died of unrelated causes, one was lost to follow-up, one was well, and three had recurrent volvulus. Twenty-four operations were performed on 23 patients and there were three deaths (13 percent mortality). There was one recurrence in two patients who underwent simple detorsion. Chronic large-bowel motility disturbances were a persistent problem in 9 of 20 (45 percent) surgical survivors. Among 27 instances of cecal volvulus, one was reduced by contrast enema and ten endoscopic attempts at decompression were unsuccessful. Twenty-six operations were done and there were four operative deaths (15 percent mortality). There were no recurrences. Large-bowel motility disorders were noted in follow-up in 3 of 22 patients (14 percent). Overall there were 10 deaths in 58 patients for a 17 percent mortality rate. These data support the importance of endoscopic decompression for sigmoid volvulus but not for cecal volvulus. Definitive treatment of both forms of volvulus should include assessment of colonic motility.

Polyvalent immune globulin and cytomegalovirus infection after renal transplantation.

To determine whether polyvalent, immune globulin (IgG) prevents cytomegalovirus (CMV) infection after cadaver renal transplantation, 28 patients were randomly allocated to receive 12 weekly infusions of 500 mg/kg of IgG (n = 15) or no treatment (n = 13). Both groups were similar with respect to age, sex, antigen mismatches, number of diabetics, and pretransplant donor/recipient CMV antibody titers. Moderately severe CMV infections occurred in 10 (77%) of 13 control subjects compared with 8 (53%) of 15 IgG-treated patients (not significant). Among those who developed CMV infections, prophylactic IgG had no effect on the severity or duration of fever, leukopenia, or hepatic enzyme elevations. Since none of the IgG-treated patients or control subjects in this study developed life-threatening CMV complications, a beneficial effect of prophylactic IgG in the small number of patients at risk for more severe CMV infections could not be excluded. However, this investigation suggests that the routine, prophylactic administration of polyvalent IgG, to prevent or to ameliorate CMV infection in unselected cadaver renal transplant recipients, is not warranted.

Unusual transplant renal angioplasty complication: case report.

We report an avulsion of a transplant upper pole renal artery following apparently successful percutaneous transluminal angioplasty (PTA) of a stenosis involving main, upper, and lower pole renal arteries. We believe that the use of a high pressure balloon was the causative factor. If the branches at the bifurcation cannot be protected and if the stenoses fail to resolve under moderate balloon insufflation pressures (less than 5-6 atmospheres), consideration should be given to surgical revascularization.
