Complications following radical cystectomy for bladder cancer in the elderly

CONTEXT: The incidence of bladder cancer increases with advancing age. Considering the increasing life expectancy and the increasing proportion of elderly people in the general population, radical cystectomy will be considered for a growing number of elderly patients who suffer from muscle-invasive or recurrent bladder cancer. OBJECTIVE: This article reviews contemporary complication and mortality rates after radical cystectomy in elderly patients and the relationship between age and short-term outcome after this procedure. EVIDENCE ACQUISITION: A literature review was performed using the PubMed database with combinations of the following keywords cystectomy, elderly, complications, and comorbidity. English-language articles published in the year 2000 or later were reviewed. Papers were included in this review if the authors investigated any relationship between age and complication rates with radical cystectomy for bladder cancer or if they reported complication rates stratified by age groups. EVIDENCE SYNTHESIS: Perioperative morbidity and mortality are increased and continence rates after orthotopic urinary diversion are impaired in elderly patients undergoing radical cystectomy. Complications are frequent in this population, particularly when an extended postoperative period (90 d instead of 30 d) is considered. CONCLUSIONS: Although age alone does not preclude radical cystectomy for muscle-invasive or recurrent bladder cancer or for certain types of urinary diversion, careful surveillance is required, even after the first 30 d after surgery. Excellent perioperative management may contribute to the prevention of morbidity and mortality of radical cystectomy, supplementary to the skills of the surgeon, and is probably a reason for the better perioperative results obtained in high-volume centers.

Peri-operative adrenocortical response to low-dose (1 microg) ACTH and relation to postoperative complications in patients undergoing elective abdominal surgery

BACKGROUND: To test the hypothesis that reduced responsiveness to adrenocorticotropin (ACTH) stimulation before elective major abdominal surgery is associated with an increased incidence of postoperative complications. METHODS: A low-dose (1 microg) ACTH test was performed the day before surgery, during the operation, on the first postoperative day, and before discharge from the hospital in 77 patients undergoing major abdominal surgery (age 62 [47;69] yrs [median, quartiles]; 30 female). Thirty-one patients undergoing minor, non-abdominal surgery (mostly inguinal hernia repair) (age 57 [40;66] yrs; 14 female) served as controls with minor surgical stress. A stimulated plasma cortisol concentration >or=500 nmol/l or an increment of >or=200 nmol/l in response to 1 microg ACTH was defined as normal. Scores for surgical stress and comprehensive risk, postoperative complications, and length of hospital stay (LOS) were assessed. RESULTS: On the day before major abdominal surgery, basal and stimulated plasma cortisol were 242 (165;299) nmol/l and 497 (404;568) nmol/l, respectively. Eighteen (23%) patients had an abnormal ACTH test, and 7 of these (39%) had complications versus 25 (42%) of the 59 patients with normal ACTH tests (P = .992). Surgical stress, comprehensive risk, and intra- and postoperative basal cortisol levels were higher and the response to ACTH stimulation smaller in patients with major abdominal compared to minor surgery. The peri-operative course of ACTH responses was not associated with complications or LOS in abdominal surgery patients. CONCLUSION: In patients scheduled for abdominal surgery, pre-operatively reduced adrenal response to stimulation with 1 microg ACTH is common but not associated with postoperative complications.

Preserving middle lobe to improve lung function in non-small-cell lung cancer

When a lung tumor arises in segment 6, the close anatomical relationship to the middle lobe bronchus may make a lower bilobectomy necessary. Sleeve lobectomy may be an alternative. These procedures were compared retrospectively in 36 patients operated on between January 2005 and December 2006 with non-small-cell lung cancer (stage I-IIIB) of the right lower lobe. Sleeve lobectomy was performed in 21 patients and bilobectomy in 15 (41%). Preoperative lung function was comparable in both groups. Radical resection was achieved in 34/36 patients. Operation time was 121 min for sleeve lobectomy and 144 min for bilobectomy. Chest tubes were removed after 5 days in both groups. Postoperative lung function was better after sleeve lobectomy than bilobectomy (forced expiratory volume in 1st sec: 78% vs. 69%). Preservation of the middle lobe by sleeve lobectomy is feasible. There was no evidence that this resection was less radical, and complication rates were similar in both groups.

Effects of adjunct electroacupuncture on severity of postoperative pain in dogs undergoing hemilaminectomy because of acute thoracolumbar intervertebral disk disease

OBJECTIVE: To compare severity of postoperative pain in dogs undergoing hemilaminectomy because of acute thoracolumbar intervertebral disk disease treated with a combination of conventional analgesics and electroacupuncture (EAP) or with conventional analgesics alone. DESIGN: Controlled clinical trial. ANIMALS: 15 dogs undergoing surgery because of acute thoracolumbar disk disease. PROCEDURES: Dogs were alternately assigned to treatment (conventional analgesics and adjunct EAP) and control (conventional analgesics alone) groups. Analgesic treatment was adjusted as necessary by the attending clinician, who was not aware of group assignment. Pain scores were assigned 1, 3, and 12 hours after surgery and every 12 hours thereafter for 72 hours by the same individual who performed acupuncture treatments. RESULTS: Total dose of fentanyl administered during the first 12 hours after surgery was significantly lower in the treatment group than in the control group, but dosages of analgesics administered from 12 through 72 hours after surgery did not differ between groups. Pain score was significantly lower in the treatment group than in the control group 36 hours after surgery, but did not differ significantly between groups at any other time. CONCLUSIONS AND CLINICAL RELEVANCE: Results provided equivocal evidence that adjunct EAP might provide some mild benefit in regard to severity of postoperative pain in dogs undergoing hemilaminectomy because of acute thoracolumbar intervertebral disk disease.

Cement-augmented anterior screw fixation of Type II odontoid fractures in elderly patients with osteoporosis

BACKGROUND CONTEXT: Closed reduction and internal fixation by an anterior approach is an established option for operative treatment of displaced Type II odontoid fractures. In elderly patients, however, inadequate screw purchase in osteoporotic bone can result in severe procedure-related complications. PURPOSE: To improve the stability of odontoid fracture screw fixation in the elderly using a new technique that includes injection of polymethylmethacrylat (PMMA) cement into the C2 body. STUDY DESIGN: Retrospective review of hospital and outpatient records as well as radiographs of elderly patients treated in a university hospital department of orthopedic surgery. PATIENT SAMPLE: Twenty-four elderly patients (8 males and 16 females; mean age, 81 years; range, 62-98 years) with Type II fractures of the dens. OUTCOME MEASURES: Complications, cement leakage (symptomatic/asymptomatic), operation time, loss of reduction, pseudarthrosis and revision surgery, patient complaints, return to normal activities, and signs of neurologic complications were all documented. METHODS: After closed reduction and anterior approach to the inferior border of C2, a guide wire is advanced to the tip of the odontoid under biplanar fluoroscopic control. Before the insertion of one cannulated, self-drilling, short thread screws, a 12 gauge Yamshidi cannula is inserted from anterior and 1 to 3 mL of high-viscosity PMMA cement is injected into the anteroinferior portion of the C2 body. During polymerization of the cement, the screws are further inserted using a lag-screw compression technique. The cervical spine then is immobilized with a soft collar for 8 weeks postoperatively. RESULTS: Anatomical reduction of the dens was achieved in all 24 patients. Mean operative time was 64 minutes (40-90 minutes). Early loss of reduction occurred in three patients, but revision surgery was indicated in only one patient 2 days after primary surgery. One patient died within the first eight postoperative weeks, one within 3 months after surgery. In five patients, asymptomatic cement leakage was observed (into the C1-C2 joint in three patients, into the fracture in two). Conventional radiologic follow-up at 2 and 6 months confirmed anatomical healing in 16 of the19 patients with complete follow-up. In two patients, the fractures healed in slight dorsal angulation; one patient developed a asymptomatic pseudarthrosis. All patients were able to resume their pretrauma level of activity. CONCLUSIONS: Cement augmentation of the screw in Type II odontoid fractures in elderly patients is technically feasible in a clinical setting with a low complication rate. This technique may improve screw purchase, especially in the osteoporotic C2 body.

The role of postoperative prophylactic antibiotics in the treatment of facial fractures: a randomized, double-blind, placebo-controlled pilot clinical study. Part 2: mandibular fractures in 59 patients

The aim of this study was to evaluate the difference between a 5-day and a 1-day postoperative course of antibiotic on the incidence of infection after mandibular fractures involving the alveolus. Sixty-two patients with fractures of the mandible involving the dentoalveolar region were randomly assigned to 2 groups, both of which were given amoxicillin/clavulanic acid 1.2 g intravenously every 8 h from admission until 24 h postoperatively. The 5-day group were then given amoxicillin/clavulanic acid 625 mg orally every 8 h for another 4 days. The 1-day group was given an oral placebo at the same intervals. Follow-up appointments were 1, 2, 4, 6, 12 weeks and 6 months postoperatively. Development of an infection was the primary end point. Fifty-nine of the 62 patients completed this study. Six of the 30 patients in the 5-day group (20%) and 6 out of the 29 in the 1-day group (21%) developed local wound infections. Three of the 6 in the 1-day group developed purulent discharge and swelling. One patient in the 5-day group developed a rash on the trunk. There were no significant differences in the incidence of infection or side effects between the groups. In fractures of the mandible involving the alveolus, a 1-day postoperative course of antibiotic is as effective in preventing infective complications as a 5-day regimen.

The role of postoperative antibiotics in facial fractures: Comparing the efficacy of a 1-day versus a prolonged regimen

BACKGROUND The goal of this study was to evaluate the influence of the duration of postoperative antibiotics (1 day vs. ≥ 5 days) on wound infections following surgical treatment of facial fractures. METHODS Three hundred thirty-nine patient case histories with a total of 498 fractures were reviewed retrospectively with regard to infections occurring within a 6-month period following surgical management. Patients were divided into two groups based on the duration of postoperative antibiotics administered. Group A consisted of 125 patients who had 1 day of postoperative antibiotics, whereas Group B consisted of 214 patients who had five or more days of postoperative antibiotics. Statistical analysis was conducted to assess for possible differences in the rate of postoperative infections. RESULTS Five patients in Group A (4%) and seven patients in Group B (3.27%) developed infections within the follow-up period. Of these 12 patients, seven had sustained multiple facial bone fractures. Eleven infections occurred in patients with mandibular fractures and one in a midfacial fracture. Statistical analysis using Fisher's exact test showed no significant difference (p = 0.77) in the incidence of infection between Groups A and B. CONCLUSION In this retrospective study, the use of prolonged postoperative antibiotics in uncomplicated mandibular and midfacial fractures had no significant benefit in reducing the incidence of infections. LEVEL OF EVIDENCE Therapeutic study, level IV.

Effect of phrenic nerve palsy on early postoperative lung function after pneumonectomy: a prospective study

BACKGROUND The issue of phrenic nerve preservation during pneumonectomy is still an unanswered question. So far, its direct effect on immediate postoperative pulmonary lung function has never been evaluated in a prospective trial. METHODS We conducted a prospective crossover study including 10 patients undergoing pneumonectomy for lung cancer between July 2011 and July 2012. After written informed consent, all consecutive patients who agreed to take part in the study and in whom preservation of the phrenic nerve during operation was possible, were included in the study. Upon completion of lung resection, a catheter was placed in the proximal paraphrenic tissue on the pericardial surface. After an initial phase of recovery of 5 days all patients underwent ultrasonographic assessment of diaphragmatic motion followed by lung function testing with and without induced phrenic nerve palsy. The controlled, temporary paralysis of the ipsilateral hemidiaphragm was achieved by local administration of lidocaine 1% at a rate of 3 mL/h (30 mg/h) via the above-mentioned catheter. RESULTS Temporary phrenic nerve palsy was accomplished in all but 1 patient with suspected catheter dislocation. Spirometry showed a significant decrease in dynamic lung volumes (forced expiratory volume in 1 second and forced vital capacity; p < 0.05) with the paralyzed hemidiaphragm. Blood oxygen saturation levels did not change significantly. CONCLUSIONS Our results show that phrenic nerve palsy causes a significant impairment of dynamic lung volumes during the early postoperative period after pneumonectomy. Therefore, in these already compromised patients, intraoperative phrenic nerve injury should be avoided whenever possible.

Major bleeding of the upper aerodigestive tract due to oral anticoagulant/antibiotic interactions

INTRODUCTION Although a well-known complication in certain medical specialties, major bleeding due to the interaction between oral anticoagulants and antibiotics has been rarely reported concerning the upper aerodigestive tract. We report three cases of life-threatening bleeding of the upper aerodigestive tract in a context of antibiotic therapy in patients treated with oral anticoagulants. CASE SERIES Three male patients under coumadin anticoagulation therapy presented major bleeding in three different contexts (epistaxis, peritonsillar abscess and postoperative course after total laryngectomy). Surgical intervention for hemostasis was required in all cases, with coagulation correction in two. Complications were severe anemia (2/3) and chronic heart failure (1/3). DISCUSSION/CONCLUSIONS Interactions between two drugs commonly used in otolaryngology can result in major bleeding. The goal of this article is to raise practitioners' awareness of a potentially fatal, although rare, complication. We also review the main preventive strategies.

Cholesteatoma surgery in children: long-term results of the inside-out technique

OBJECTIVE To present the anatomical and functional results of the inside-out technique applied in pediatric cholestetaoma surgery and to evaluate functionality with good hearing results against radicality with lower recurrence rate. METHODS Retrospective analysis and evaluation of the postoperative outcome in a consecutive series of 126 children or 130 ears operated between 1992 and 2008. With the inside-out technique, cholesteatoma is eradicated from the epitympanum toward the mastoid and, as a single stage procedure, functional reconstruction of the middle ear is achieved by tympanoossiculoplasty. RESULTS In 89.2% of all cases, the ear was dry postoperatively. 80.9% of the ears reached a postoperative air-bone gap of 30 dB or less and the median air conduction hearing threshold was 29 dB; in 60.9% of all cases, hearing was postoperatively improved. The recurrence rate was 16.2% in a mean postoperative follow-up 8.5 years. Altogether, 48 ears (36.9%) underwent revision surgery. The complication rate was 3.1% and involved only minor complications. CONCLUSION The inside-out technique allows a safe removal of cholesteatoma from the epitympanum toward the mastoid with a single-stage reconstruction of the ossicular chain. For this reason we support our individual approach, which allows creation of the smallest possible cavity for the size of the cholesteatoma. Our results confirm that the inside-out technique is effective in the treatment of pediatric cholesteatoma.

Postoperative renal function preservation with nonischemic femoral arterial cannulation for thoracoabdominal aortic repair.

BACKGROUND: Renal failure after thoracoabdominal aortic repair is a significant clinical problem. Distal aortic perfusion for organ and spinal cord protection requires cannulation of the left femoral artery. In 2006, we reported the finding that direct cannulation led to leg ischemia in some patients and was associated with increased renal failure. After this finding, we modified our perfusion technique to eliminate leg ischemia from cannulation. In this article, we present the effects of this change on postoperative renal function. METHODS: Between February 1991 and July 2008, we repaired 1464 thoracoabdominal aortic aneurysms. Distal aortic perfusion was used in 1088, and these were studied. Median patient age was 68 years, and 378 (35%) were women. In September 2006, we began to adopt a sidearm femoral cannulation technique that provides distal aortic perfusion while maintaining downstream flow to the leg. This was used in 167 patients (15%). We measured the joint effects of preoperative glomerular filtration rate (GFR) and cannulation technique on the highest postoperative creatinine level, postoperative renal failure, and death. Analysis was by multiple linear or logistic regression with interaction. RESULTS: The preoperative GFR was the strongest predictor of postoperative renal dysfunction and death. No significant main effects of sidearm cannulation were noted. For peak creatinine level and postoperative renal failure, however, strong interactions between preoperative GFR and sidearm cannulation were present, resulting in reductions of postoperative renal complications of 15% to 20% when GFR was <60 mL>/min/1.73 m(2). For normal GFR, the effect was negated or even reversed at very high levels of GFR. Mortality, although not significantly affected by sidearm cannulation, showed a similar trend to the renal outcomes. CONCLUSION: Use of sidearm cannulation is associated with a clinically important and highly statistically significant reduction in postoperative renal complications in patients with a low GFR. Reduced renal effect of skeletal muscle ischemia is the proposed mechanism. Effects among patients with good preoperative renal function are less clear. A randomized trial is needed.
