The Influence of Technical Complications on Postoperative Outcome and Survival After Esophagectomy

Background The dismal survival associated with esophagectomy for cancer has led to the search for potentially correctable factors responsible for this poor prognosis. Although it is intuitive that technical complications could increase postoperative mortality, the effect on long-term survival is controversial. Methods From 1990 to 2002, 434 patients underwent resection for squamous cell carcinoma of the intrathoracic esophagus. Prospectively collected data were reviewed for the presence of technical complications. Patient, tumor, and operative variables, postoperative outcome, and survival were compared between patients with technical complications and those without. Prognostic factors were assessed by multivariate analysis. Results Technical complications occurred in 98 (22.6%) patients. Patients with technical complications had a higher prevalence of cardiac disease, more proximal tumors, and more cervical anastomoses. Technical complications were associated with an increased rate of pulmonary complications (37.8% vs. 10.7%; P < .001) and increased hospital mortality (9.2% vs. 3.3%; P = .025), but no difference in 30-day mortality (2% vs. 1.2%; P = .6). Poor-prognostic factors for survival included male sex, stage III/IV disease, cirrhosis, proximal tumors, and R1/R2 resection, but not technical complications. Conclusions Although immediate postoperative outcome and hospital mortality rates were increased, no effect on long-term survival was seen in patients with complications related to errors in surgical technique.

Effects of Neoadjuvant Therapy on Perioperative Morbidity in Elderly Patients Undergoing Esophagectomy for Esophageal Cancer

Background The use of cytoreductive therapy followed by surgery is preferred by many centers dealing with locally advanced esophageal cancer. However, the potential for increase in mortality and morbidity rates has raised concerns on the use of chemoradiation therapy, especially in elderly patients. The aim of this study was to assess the effects of induction therapy on postoperative mortality and morbidity in elderly patients undergoing esophagectomy for locally advanced esophageal cancer at a single institution. Methods Postoperative mortality and morbidity of patients ≥70 years old undergoing esophagectomy after neoadjuvant therapy, between January 1992 and October 2005 for cancer of the esophagus or esophagogastric junction, were compared with findings in younger patients also receiving preoperative cytoreductive treatments. Results 818 patients underwent esophagectomy during the study period. The study population included 238 patients <70 years and 31 ≥70 years old undergoing esophageal resection after neoadjuvant treatment. Despite a significant difference in comorbidities (pulmonary, cardiological and vascular), postoperative mortality and morbidity were similar irrespective of age. Conclusions Elderly patients receiving neoadjuvant therapies for cancer of the esophagus or esophagogastric junction do not have a significantly increased prevalence of mortality and major postoperative complications, although cardiovascular complications are more likely to occur. Advanced age should no longer be considered a contraindication to preoperative chemoradiation therapy preceding esophageal resection in carefully selected fit patients.     

Complications of hip fractures: A review

Nowadays, fracture surgery represents a big part of the orthopedic surgeon workload, and usually has associated major clinical and social cost implications. These fractures have several complications. Some of these are medical, and other related to the surgical treatment itself. Medical complications may affect around 20% of patients with hip fracture. Cognitive and neurological alterations, cardiopulmonary affections (alone or combined), venous thromboembolism, gastrointestinal tract bleeding, urinary tract complications, perioperative anemia, electrolytic and metabolic disorders, and pressure scars are the most important medical complications after hip surgery in terms of frequency, increase of length of stay and perioperative mortality. Complications arising from hip fracture surgery are fairly common, and vary depending on whether the fracture is intracapsular or extracapsular. The main problems in intracapsular fractures are biological: vascularization of the femoral head, and lack of periosteum -a major contributor to fracture healing- in the femoral neck. In extracapsular fractures, by contrast, the problem is mechanical, and relates to load-bearing. Early surgical fixation, the role of anti-thromboembolic and anti-infective prophylaxis, good pain control at the perioperative, detection and management of delirium, correct urinary tract management, avoidance of malnutrition, vitamin D supplementation, osteoporosis treatment and advancement of early mobilization to improve functional recovery and falls prevention are basic recommendations for an optimal maintenance of hip fractured patients.

Perioperative Prostaglandin E1 Treatment for the Prevention of Postoperative Complications After Esophagectomy: A Randomized Clinical Trial

Purpose We conducted a prospective randomized clinical study to examine whether perioperative prostaglandin E1 (PGE1) could help in the prevention of postoperative complications after esophagectomy for esophageal cancer.Methods Forty patients with esophageal cancer eligible for radical esophagectomy were randomly assigned to an experimental group (n = 20), given perioperative PGE1, or to a control group (n = 20), given standard postoperative treatment. The main clinical endpoints examined were the incidence of postoperative complications, hospitalization, duration of systemic inflammatory response syndrome (SIRS), portal vein blood flow, and serum bilirubin levels.Results Severe postoperative complications developed in five patients in the control group and two in the PGE1 group. There was one surgery-related death in the control group. The duration of SIRS was significantly shorter in the PGE1 group than in the control group (5.74 days vs 7.50 days; P = 0.047). Portal vein flow was also significantly lower on postoperative day (POD) 1 in the control group than in the PGE1 group (P = 0.042). Maximum postoperative serum bilirubin levels were significantly lower in patients treated with PGE1, at 2.91 vs 4.38mg/dl in the control group (P = 0.040).Conclusions The perioperative administration of PGE1 helps maintain adequate portal blood flow, improves hyperbilirubinemia, and attenuates the duration of SIRS, thereby reducing the risk of postoperative complications after esophagectomy and lymphadenectomy for esophageal cancer.     

Complications of thyroid surgery

Background: The morbidity of thyroid surgery is low. Despite this, some authors advocate a subtotal thyroidectomy instead of a total thyroidectomy, to avoid the higher morbidity associated with a total thyroidectomy. Methods: We retrospectively evaluated the complications of thyroid surgery in Leiden between January 1, 1982 and October 1, 1990. Three hundred forty-one patients—261 women and 80 men—had 356 operations; 15 patients were operated on twice; there were 152 total hemithyroidectomies, 3 subtotal hemithyroidectomies, 33 total thyroidectomies, 122 bilateral subtotal hemithyroidectomies, 12 combinations of total and subtotal hemithyroidectomies, and 34 other operations. Results: Calculated for the nerves at risk (n=489), the percentage of permanent recurrent nerve lesions was 3.1 (in the 5 most recent years it was 1.2%). There was no significant difference between total or subtotal (hemi)thyroidectomies. Initial symptomatic hypocalcemia necessitating supplementation was encountered 42 times (12.5%). The occurrence of permanent symptomatic hypocalcemia (6%) was not significantly different between total and subtotal (hemi)thyroidectomies (p=0.06). The duration of surgery was 137.8 min for bilateral subtotal thyroidectomies and 182.9 min for bilateral total thyroidectomies (p<0.0001). There was no difference in blood loss between total and subtotal (hemi)thyroidectomies. Conclusions: Because total thyroidectomy carries a risk of complications similar to that for subtotal thyroidectomy, it is not logical to avoid total resections. If the number of total resections were increased, it is anticipated that fewer reoperations, which involve a relatively high morbidity rate, would have to be performed.Results of this work were presented at the 46th Annual Cancer Symposium of The Society of Surgical Oncology, Los Angeles, March 18–21, 1993.     

The Impact of Postoperative Complications on Long-Term Outcomes Following Curative Resection for Colorectal Cancer

Background This study aimed to investigate the impact of postoperative complications on long-term survival and disease recurrence in patients who underwent curative resection for colorectal cancer. Method Patients who underwent radical resection for colorectal cancer with curative intent from January 1996 to December 2004 were included. Operative mortality and morbidity were documented prospectively. Factors that might affect long-term outcome were analyzed with multivariate analysis. Results Curative resection was performed in 1657 patients (943 men), and the median age was 70 years (range: 24–94 years). The 30-day mortality was 2.4%, and the complication rate was 27.3%. Age over 70 years (P < .001, odds ratio: 2.06, 95% CI: 1.63–2.61), male gender (P = .001, odds ratio: 1.49, 95% CI: 1.19–1.88), emergency operation (P < .001, odds ratio: 3.14, 95% CI: 2.26–4.35) and rectal cancer (P < .001, odds ratio: 1.41, 95% CI: 1.25–1.61) were associated with a significantly higher complication rate. With exclusion of patients who died within 30 days, the median follow-up of the surviving patients was 45.3 months. The 5-year overall survival was 64.9%, and the overall recurrence rate was 29.1%. The presence of postoperative complications was an independent factor associated with a worse overall survival (P = .023, hazard ratio: 1.26; 95% CI: 1.03–1.52) and a higher overall recurrence rate (P = .04, hazard ratio: 1.26; 95% CI: 1.01–1.57). Conclusion The presence of postoperative complication not only affects the short-term results of resection of colorectal cancer, but the long-term oncologic outcomes are also adversely affected. Long-term outcomes can be improved with efforts to reduce postoperative complications.     

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.     

Association of Splenectomy With Postoperative Complications in Patients With Proximal Gastric and Gastroesophageal Junction Cancer

Background: Splenectomy has been associated with increased morbidity after gastrectomy for gastric cancer. Resection of proximal versus distal tumors is associated with a higher morbidity. Because splenectomy is more commonly performed in resection of proximal tumors, these analyses may be biased. The aim of this study was to describe the association of splenectomy with complications in patients undergoing resection of proximal gastric and gastroesophageal junction (GEJ) cancers.Methods: From July 1985 to August 2001, 335 patients underwent resection of proximal gastric or GEJ (type II and III) cancers. Clinical and pathologic factors were retrieved from a prospective database.Results: Overall morbidity was 59% (infectious complications, 41%; noninfectious complications, 36%), and mortality was 4.5%. Splenectomy was associated with a higher rate of infectious complications (57% vs. 33%; P < .01) but not of noninfectious complications (39% vs. 34%; not significant) or mortality (4% vs. 5%; not significant). Splenectomy was also associated with a higher rate of infectious complications on multivariate analysis (hazard ratio, 2.4; P < .01).Conclusions: Morbidity after resection of proximal gastric and GEJ cancer is significant; splenectomy is associated with increased morbidity, but not mortality, in these patients. Because these complications can be managed without an increase in mortality, splenectomy should be performed when indicated by the extent of the tumor.     

Transcervical Gastric Tube Drainage Facilitates Patient Mobility and Reduces the Risk of Pulmonary Complications After Esophagectomy

Background  Standard nasogastric decompression following esophagectomy is associated with reduced patient comfort and mobility and impaired hypopharyngeal function—predisposing the patient to sinusitis, pharyngitis, and the risk of aspiration. In this study, we evaluate the results of the transcervical gastric tube drainage in the setting of esophagectomy. Methods  Transcervical gastric tube decompression was performed on 145 consecutive patients undergoing open esophagectomy between 2003 and 2007. Postoperative outcome variables include morbidity, mortality, esophagostomy duration, and length of stay. Results  There were 107 males and 38 females (median age = 66; range = 37–87). Perioperative mortality was 2.8%. Major complications included five anastomotic leaks (3.4%), ten pneumonias (6.9%), two myocardial infarctions (1.4%), and the need for reoperation in four patients (bleeding, dehiscence). Median duration of transcervical drainage was 8 days. No tubes were dislodged prematurely. There were no bleeding complications. Four patients developed cellulitis near the cervical gastric tube site and were treated successfully with antibiotics and/or tube removal. Conclusions  Transcervical gastric decompression can be performed safely with minimal complication risk. Inadvertent tube removal was not encountered in this series. The use of this technique may help to promote accelerated patient mobilization, greater patient comfort, and a durable means of gastric decompression.

Risk Prediction Scores for Postoperative Mortality After Esophagectomy: Validation of Different Models

Background  Different prediction models for operative mortality after esophagectomy have been developed. The aim of this study is to independently validate prediction models from Philadelphia, Rotterdam, Munich, and the ASA. Methods  The scores were validated using logistic regression models in two cohorts of patients undergoing esophagectomy for cancer from Switzerland (n = 170) and Australia (n = 176). Results  All scores except ASA were significantly higher in the Australian cohort. There was no significant difference in 30-day mortality or in-hospital death between groups. The Philadelphia and Rotterdam scores had a significant predictive value for 30-day mortality (p = 0.001) and in-hospital death (p = 0.003) in the pooled cohort, but only the Philadelphia score had a significant prediction value for 30-day mortality in both cohorts. Neither score showed any predictive value for in-hospital death in Australians but were highly significant in the Swiss cohort. ASA showed only a significant predictive value for 30-day mortality in the Swiss. For in-hospital death, ASA was a significant predictor in the pooled and Swiss cohorts. The Munich score did not have any significant predictive value whatsoever. Conclusion  None of the scores can be applied generally. A better overall predictive score or specific prediction scores for each country should be developed. No score generally applicable
