[Immediate postoperative complications after total hip replacement].

With the object of illustrating the immediate postoperative complications connected with total hip replacement, a material of 512 hip replacements carried out in the Orthopaedic Department in Viborg Hospital during the period 1982-1987 was reviewed. Complications of significance for the postoperative course occurred in 16% and the mortality was 0.4%. The complications of greatest significance were cardiac (3.3%), renal involvement (2.5%) and thromboembolic complications (3.5%) (pulmonary embolism 1.8% and deep venous thrombosis 2.9%). Advanced age, preoperative cardiovascular conditions and obesity predisposed to these complications and, similarly, increased frequency of cardiac complications was found with increased duration of anaesthesia. Finally, a connection was found between peroperative and postoperative episodes of hypotension and renal involvement.

[Prevention of intra, and postoperative complications. Capabilities of the anesthesist].

Prevention of intra- and postoperative complications is one of the main tasks of the anesthesiologist. It is achieved by avoidance of specific anesthesiological dangers and mistakes and by adjustment of anesthetic techniques to the course of operation. Recognition and consideration of preexisting diseases as possible causes of complications and appropriate preoperative measures are the responsibility of the surgical-anesthesiological team. Depending on the given situation and the risk state of the patient during and after operation, special anesthetic procedures may be necessary.

Postoperative complications predict recurrence of Crohn's disease.

OBJECTIVE: To find out if any of six variables influenced the incidence and timing of recurrence after a first resection for Crohn's disease. DESIGN: Open study. SETTING: University hospital, Germany. SUBJECTS: 104 surviving patients of 106 who underwent a first resection for Crohn's disease between January 1976 and December 1990. MAIN OUTCOME MEASURES: Association between 6 variables (age, sex, site of diseased bowel, histological evidence of Crohn's disease, indication for operation, and incidence of postoperative complications) and incidence and time of recurrence after the first operation. RESULTS: Patients were followed up for a mean of 4.5 years (range 1-16). Presentation with acute perforation was associated with a higher incidence of recurrence (10/14 compared with 26/90), chi square 7.90, p = 0.005) and more than doubled the risk of that recurrence developing with six years (log rank chi square 11.7, p = 0.02); the same was true for development of a postoperative complication for which the corresponding figures were 14/26 compared with 22/78, chi square 4.59, p = 0.03, and log rank chi square 6.1, p = 0.01. CONCLUSION: These data support the hypothesis that there may be two types of Crohn's disease: an aggressive type that perforates and is prone to early relapse, and one that develops more slowly with an obstructive pattern, and which relapses less often and after a longer disease free interval. The development of postoperative complications is a previously unrecognised risk factor for early recurrence in Crohn's disease.

Neoadjuvant chemotherapy does not increase postoperative complication rate after resection of colorectal liver metastases.

BACKGROUND: This paper discusses, whether neoadjuvant chemotherapy has an impact on the rate of postoperative complications after primary resection of liver metastases from colorectal carcinoma. METHODS: Of 183 patients 64 were studied. The patients were subdivided into two matched groups of 32 patients each-prior neoadjuvant chemotherapy (CT-group) vs. (control-group, primary resection). RESULTS: There were no postoperative complications in 24 patients of the control group (75%) and 26 patients of the CT-group (81%). Following prior chemotherapy, no major complications such as liver failure were observed, even after extended resections. CONCLUSION: Neoadjuvant chemotherapy prior to surgical resection of colorectal liver metastases does not result in an increase of postoperative morbidity and mortality.

A comparative study of postoperative complications after hepatectomy in patients with and without chronic liver disease.

BACKGROUND: Although hepatic resection is the most reliable treatment for hepatocellular carcinoma, impaired liver function because of cirrhosis or chronic hepatitis contributes to relatively high rates of postoperative complications. We have reviewed a series of hepatectomies at our institution and investigated risk factors for complications after hepatectomy in patients with impaired liver compared with patients with normal liver. METHODS: From October 1994 to March 1998, 277 hepatectomies for hepatocellular carcinoma, cholangiocellular carcinoma, metastatic liver tumors, and other hepatic diseases were performed. In an attempt to clarify the safety of hepatectomy for the impaired liver at our institution, we did a comparative study of postoperative complications after hepatectomy in 2 groups: patients with impaired livers (187 hepatectomies) and patients with normal livers (90 hepatectomies). RESULTS: Of the 277 hepatectomies, bile leakage occurred in 25 patients (16 in impaired livers vs 9 in normal livers), abdominal infection in 45 patients (30 vs 15 patients), wound infection in 13 patients (9 vs 4 patients), pleural effusion in 52 patients (35 vs 17 patients), atelectasis in 26 patients (17 vs 9 patients), pneumonia in 4 patients (3 vs 1 patients), ileus in 6 patients (3 vs 3 patients), intra-abdominal hemorrhage in 3 patients (0 vs 3 patients), and hyperbilirubinemia in 5 patients (4 vs 1 patients). Hepatic insufficiency and hospital death were not experienced in this series. The mean postoperative hospital stay was 22.9 days (23.5 vs 23.1 days), and except for intra-abdominal hemorrhage there was no statistically significant difference between the 2 groups. CONCLUSIONS: Hepatectomy for the impaired liver is now as safe a procedure as for the normal liver, provided the overall guidelines outlined in our algorithm are followed.

Postoperative complications and visual results in uniocular pediatric traumatic cataract.

BACKGROUND AND OBJECTIVES: This study was prospectively carried out to evaluate the postoperative complications and visual results following posterior chamber intraocular lens (PCIOL) implantation in children with unilateral traumatic cataract. PATIENTS AND METHODS: We prospectively evaluated 40 children, 12 years or younger, with traumatic cataract (blunt trauma, n = 22 eyes, repaired penetrating eye injury, n = 18 eyes) undergoing PCIOL implantation with a minimum follow-up period of one year. Children with posterior segment ocular injury were excluded. RESULTS: The postoperative complications were significantly higher in the penetrating eye injury group as compared to blunt trauma group (ie, pupillary capture 44.44% vs 9.09%, posterior capsulotomy rate 83.33% vs 40.90% and IOL decentration 27.77% vs 4.54%). The final visual acuity was 6/12 or better in 38.8% and 86.36% of eyes with penetrating eye injury and blunt trauma, respectively. CONCLUSION: Extracapsular cataract extraction (ECCE) with PCIOL implantation in traumatic cataract following blunt trauma results in better visual outcome and fewer complications compared to penetrating eye injury if the posterior segment is not involved.

Postoperative complications and mortality after surgery for gastric cancer.

Complication rates and postoperative mortality were studied in 1010 consecutive patients entered into the Norwegian Stomach Cancer Trial. Twenty-eight per cent of the patients had one or more complications (31% of the men and 21% of the women). General complications (pneumonia, thromboembolic, and cardiac) were most frequent. The postoperative mortality rate for resected patients was 8.3% (63 of 763). Complication and mortality rates were highest for proximal resections (52% and 16%) followed by total gastrectomy (38% and 8%), subtotal resection (28% and 10%), and distal resection (19% and 7%). By logistic regression analysis it was found that age, sex, operative procedure, prophylactic antibiotics, and splenectomy were significantly related to postoperative complications. The odds ratio for complication for men versus women was 1.75: for no antibiotics versus antibiotic prophylaxis it was 2.5. Relative to distal resection the odds ratio for complications after subtotal resection was 2.2, for total gastrectomy was 3.9, and for proximal resection was 7.6. Age and sex were the only factors that affected operative mortality. The odds ratio for mortality for men versus women was 2.3. The odds ratio for operative mortality was 2.2 when the age of the patient increased with 10 years.

Postoperative complications of repeat hepatectomy for liver metastasis from colorectal carcinoma.

BACKGROUND/AIMS: When a repeat hepatectomy is possible, it is the most effective treatment modality for recurrent colorectal liver metastasis. The aim of this study was to evaluate the surgical risks of repeat hepatectomy for liver metastasis from colorectal carcinoma. METHODOLOGY: Between 1986 and 1996, 60 patients with hepatic metastasis from colorectal carcinoma underwent surgery in the Department of Surgery I, Oita Medical University. Ten of them underwent a repeat hepatectomy. The cases of these 10 patients were studied retrospectively; in particular, postoperative complications and intraoperative blood loss were compared between the initial and second operation. RESULTS: During the second surgery, recurrence was detected adjacent to the hepatic stump in 9 of the 10 patients. During the initial surgery, 6 underwent non-anatomic resections, and 4 had anatomic resection, including 1 extended lobectomy, 1 lobectomy, and 2 segmentectomies. For the second surgery, 3 had anatomic resections, including 2 lobectomies, and 1 segmentectomy, and 7 underwent non-anatomic resections. There were no mortalities during the initial or second operation. There was no morbidity following the initial surgeries and 7 postoperative complications (intraabdominal abscess, 4 cases; biloma, 3 cases) following the second surgeries. Mean blood loss during the second operation (1044 mL) was significantly greater than during the initial operation (561 mL). CONCLUSIONS: The present results show that repeat hepatectomy for recurrent liver metastasis from colorectal carcinoma resulted in significantly greater intraoperative blood loss and postoperative complications than those of the initial surgeries. The blood loss and complications in the second operation, the one for the recurrence, were directly associated with the fact that the recurrence was so close to the hepatic stump. Since the resection line in the second surgery was adjacent to the hepatic hilus, resection of the lesion caused much more injury to the main bile duct and main portal vein than that caused by the.

Procalcitonin as a marker of postoperative complications.

OBJECTIVE: Procalcitonin (PCT) is a 116 amino acid peptide that functions as a pro-hormone for calcitonin in the C cells of the thyroid gland. Large quantities of intact PCT are present in the blood of patients with sepsis, particularly when organ dysfunction occurs. PCT has been proposed as an early marker of postoperative complications. The aim of this study was to examine the diagnostic accuracy of PCT as a marker of postoperative complications by systematically reviewing the existing literature. MATERIAL AND METHODS: The databases PubMed, Embase and the Cochrane Library were searched to find studies on the diagnostic accuracy of PCT in the postoperative phase. Primary studies were retrieved using specific inclusion and exclusion criteria. RESULTS: A total of nine studies were included. These studies were heterogeneous regarding the spectrum of patients, complications, design and methodological quality according to QUADAS (quality assessment of studies of diagnostic accuracy). This could explain the marked variation in diagnostic accuracy. Considering all types of complications the sensitivity ranged from 37% to 100% and the specificity from 70% to 100%. On examining the infectious complications separately, it was found that the sensitivity ranged from 70% to 86% and the specificity from 45% to 98%. CONCLUSIONS: Owing to a pronounced heterogeneity among the existing studies, the diagnostic accuracy of PCT as a marker for postoperative complications is not yet sufficiently clarified.

[Antioxidants ceruloplasmin and lactoferrin in the prevention and treatment of postoperative complications in cancer patients].

Ceruloplasmin and laprote based on natural protein antioxidants were used in the treatment and prevention of postoperative complications in 174 patients after extensive interventions for cancer. Development of pyoseptic complications during the postoperative period is associated with activation of lipid peroxidation, decreased functional activity of the antioxidant component of detoxication, suppressed T-cellular immunity, and development of polyorgan failure in the presence of endogenous toxemia. Systemic treatment with laprote (50 pts) and ceruloplasmin (33 pts) after surgical cleansing and draining of purulent focus stimulated activation of antioxidant defense, decreased the intensity of oxidative processes, normalized the lymphocytic component of immunity, and promoted resolution of polyorgan, primarily hepatic failure. Local therapy with laprote (60 pts) promoted rapid regression of local pyoinflammatory processes. Intraoperative blood loss complicated by hemorrhagic shock had a deep impact on the oxidative/antioxidant system, which correlated with the severity of hypoxia. Addition of ceruloplasmin, a potent antioxidant, to therapy of these patients (n = 31) optimized the course of recovery by stimulating the resolution of posthypoxic polyorgan failure, recovery of the oxidant/antioxidant balance, and decreasing the incidence of postoperative pyoinflammatory complications.

Postoperative complications in patients with obstructive sleep apnea syndrome undergoing hip or knee replacement: a case-control study.

OBJECTIVE: To identify and assess the impact of postoperative complications in patients with unrecognized or known obstructive sleep apnea syndrome (OSAS) undergoing hip replacement or knee replacement compared with control patients undergoing similar operations. Although OSAS is a risk factor for perioperative morbidity, data quantifying the magnitude of the problem in patients undergoing non-upper airway operations are limited. PATIENTS AND METHODS: This retrospective, case-control study from a single academic medical institution included patients diagnosed as having OSAS between January 1995 and December 1998 and undergoing hip or knee replacement within 3 years before or anytime after their OSAS diagnosis. Patients with OSAS were subcategorized as having the diagnosis either before or after the surgery and also, regardless of time of diagnosis, by whether they were using continuous positive airway pressure (CPAP) prior to hospitalization. Matched controls were patients without OSAS undergoing the same operation. Interventions were defined specifically as administration of a particular treatment in the context of each complication, eg, supplemental oxygen, implementation of additional monitoring such as oximetry for hypoxemia, or transfer to the intensive care unit (ICU) for cardiac ischemia concerns. Postoperative complications were assessed for all patients in the different categories and included respiratory events such as hypoxemia, acute hypercapnia, and episodes of delirium. Serious complications were noted separately, including unplanned ICU days, reintubations, and cardiac events. The length of hospital stay was also tabulated. RESULTS: There were 101 patients with the diagnosis of OSAS in this study and 101 matched controls. Thirty-six patients had their joint replacement before OSAS was diagnosed, and 65 had surgery after OSAS was diagnosed. Of the latter 65 patients, only 33 were using CPAP at home preoperatively. Complications were noted in 39 patients (39%) in the OSAS group and 18 patients (18%) in the control group (P=.001). Serious complications occurred in 24 patients (24%) in the OSAS group compared with 9 patients (9%) in the control group (P=.004). Hospital stay was significantly longer for the OSAS patients at a mean +/- SD of 6.8 +/- 2.8 days compared with 5.1 +/- 4.1 days for the control patients (P<.007). CONCLUSION: Adverse postoperative outcomes occurred at a higher rate in patients with a diagnosis of OSAS undergoing hip or knee replacement compared with a group of matched control patients.

[Prevention of postoperative complications in patients with stomach cancer using an antioxidant complex].

The suitability of complex administration of antioxidants (vitamins C, E and A) for prevention of postoperative complications was assessed in a randomized study which included 197 cases of gastric cancer. The treatment was followed by a lowering of lipid peroxidation process. In a group of 95 patients who had received the drugs preoperatively, the postoperative complication rate dropped from 30.9 to 1.9%.

[Weak stress factors in the prevention of postoperative complications in elective orthopedic surgery].

Based on their personal and literature data the authors propose to use weak stressogenic factors (pyrogenal and interrupting normobaric hypoxia) as an element of preoperative preparation of patients for prevention of postoperative complications. The using of this method made the frequency of postoperative complications in the area of the operation wound twice as rare, outside the wound--three times as rare.

Postoperative complications among octogenarians after cardiovascular surgery.

BACKGROUND: The octogenarian patient is often perceived as too fragile to undergo cardiothoracic surgery. Our study aimed to compare postoperative complications in patients aged less than 80 versus elderly patients (80 years or more) after surgical cardiac intervention (coronary artery bypass or valve replacement). METHODS: Subjects were all patients (n = 8,361) who had an open-heart procedure, either coronary artery bypass or valve implantation or replacement, at two medical centers located in northern Virginia using the same surgical group. A computerized medical record database was reviewed to determine preoperative risk factors and postoperative outcomes. Predictors of complications were identified by univariate and multivariate logistic regression. RESULTS: A total of 3,214 complications were recorded. The most prevalent complications were prolonged ventilation time in the intensive care unit, reoperation for bleeding, and pneumonia. The overall mortality rate was 2.4% (204 of 8,361). Persons aged over 80 years had nearly double the mortality rate compared with younger patients (4.1% [18 of 444] to 2.3% [186 of 7,917]). Age greater than 80 years (odds ratio = 2.65, 95% confidence interval = 2.18 to 3.22) and male gender (odds ratio = 0.62, 95% confidence interval = 0.56 to 0.69) were the best univariate predictors of a single postoperative complication. CONCLUSIONS: Octogenarian patients manifested twice the risk of death from a cardiac intervention with an average 2-day longer hospital stay compared with their younger counterparts. Furthermore, octogenarians were at markedly higher risk of nonfatal postoperative complications.

[Intraoperative and early postoperative complications of vagotomy].

Intraoperative complications occurred in 28 (2.8%) and early postoperative complications in 157 (15.7%) out of 1,000 operations for vagotomy in duodenal ulcer (109 truncal, 64 selective, 445 isolated SPV, and 372 SPV combined with draining operations). Postoperative lethality was 1.3%. Controllable types of complications were encountered in 2.6%, prognostic in 9.6%, and non-prognostic in 5.7% of cases. The first two groups of complications accounted for two thirds of the total number and determined the lethal outcome in 0.7% of the fatal cases. Thus, mastering of the operative techniques and realization of the complex of preventive measures allows the postoperative results of vagotomy to be considerably improved.
