[Postoperative complications and fatalities in surgical therapy of colon carcinoma. Results of the German multicenter study by the Colorectal Carcinoma Study Group].

In a prospective multicenter study an analysis of postoperative morbidity and mortality of 1224 patients with colon carcinoma treated in 7 departments of surgery was performed. The postoperative morbidity rate was 23.2% in elective surgery and 39.1% in emergency surgery. Postoperative mortality was 3.4% in elective cases and 11.6% in emergency cases. Preoperative associated diseases, which are more frequent in higher age, advanced tumor stage, and postoperative non-surgical complications rise operative mortality. However, surgical complications increase postoperative mortality only in cases of anastomotic leaks. The rates of postoperative complications depended on different surgical departments. Departments performing a delayed tumor resection in emergency surgery had better results. In elective cases the standard of oncological resections should be observed. In emergency cases operative procedure and extension of the resection should be planed in consideration of preoperative risk factors of the individual patient.

Intra- and postoperative complications of donor nephrectomies.

INTRODUCTION: Living-donor renal transplantation has become common worldwide. However, living-donor nephrectomy is not a complication-free procedure. This retrospective study reviews the intra-and postoperative risks and complications of donor nephrectomies at our institution between 1994 and 2002. METHOD: Two hundred fifty-seven consecutive donor nephrectomy patients were evaluated using medical records and anesthetic charts. RESULTS: The mean age of living donors was 42 +/- 12 years: 19 were older than 61 years, and 143 (55.6%) were women. Anesthesia for donor nephrectomy included general anesthesia, combined spinal-epidural anesthesia (CSE), general + CSE, and general + epidural anesthesia. We observed 51 intra- and postoperative complications in 26 patients. The minor complication rate was 10.1%. The duration of surgery was 3.56 +/- 0.26 hours (range, 2 to 5 hours). Serum creatinine levels were increased significantly (P < .05) on postoperative days 1, 3, and 5 compared with the preoperative levels (P < .05). There was no mortality. CONCLUSIONS: Like other surgical operations, living-donor nephrectomy is associated with intra- and postoperative complications. Although these complications are minor, maximal efforts must be applied in the anesthetic approach to minimize donor complications, and donors should be informed about potential risks.

[Postoperative complications of liver transplantation: relationship with mortality].

BACKGROUND AND OBJECTIVE: Liver transplant is an effective procedure for fulminant hepatitis or chronic liver disease and offers an adequate quality of life. However, even though it is a consolidated treatment, patients can develop serious complications in the immediate postoperative course. PATIENTS AND METHOD: Prospective observational study of 131 patients admitted in our intensive care unit after liver transplant surgery. We studied variables related with the development of complications and their relation to outcome. RESULTS: Intensive care unit mortality was 11.5%. Median stay was 4 days. 90% of patients presented 2 or more complications. Hyperglycemia, thrombocytopenia and hypothermia were the most frequent complications but they were not related with mortality. Less frequent but related to outcome complications were acute renal failure (23.6% mortality vs. 1.3%; p < 0.01), ADRS (63.6% vs 6.7%; p < 0,01), low cardiac output (71.4% vs 4.3%; p < 0.01), > or = 2 vasoactive drugs (61.9% vs 1.8%; p < 0.01), encephalopathy (37.5% vs 9.8%; p < 0.05), pneumonia (80% vs 8%; p < 0.01) and hemorrhage (29.4% vs 8.8%; p < 0.05). Graph ischemia, coagulopathy, reperfusion syndrome and use of blood derivatives during surgery were factors related with the development of complications and mortality. Multivariate analysis showed a relationship with mortality and low cardiac output, number of vasoactive drugs and total time of graft ischemia. CONCLUSIONS: Complications during the postoperative course of liver transplant are frequent but most of them have no effect on prognosis. The negative effect of severe complications should be limited by optimizing the hemodynamic support in these patients and minimizing ischemia of transplanted organs.

[Postoperative complications in abdominal surgery--what do they cost?].

In this study of 154 patients with major abdominal cancer surgery, 41 postoperative complications occurred and caused additional total costs of DM 205.993,-, DM 5.024,- per case, respectively, where the special personnel costs were not accounted for. There was a significant difference between single and multiple complications as well as for early and late complication costs. Economic analyses are necessary to determine budgets of medical departments with extended and cost-intensive treatment, such as cancer surgery, to maintain optimal care for the patients.

Comparison of surgical and postoperative complications of vaginal hysterectomy and Manchester procedure.

OBJECTIVE: The Manchester procedure (MP) was compared to vaginal hysterectomy (VH). Surgical and postoperative complications were evaluated. MATERIAL AND METHODS: A retrospective review of women undergoing VH and MP for uterine prolapse was performed. All the operations were performed between 1974-1994. MP was performed in 190 patients and VH (Heaney technique) in 231 women. RESULTS: MP patients, when compared to VH patients, were more likely to be older and postmenopausal at the time of surgery. Statistically significant differences were found for operative time and blood loss. This difference was not dependent on the performance of anterior or posterior repair. CONCLUSIONS: We suggest the use of MP as an alternative to VH in the absence of uterine pathology in appropriate candidates with uterine prolapse.

A margin-negative R0 resection accomplished with minimal postoperative complications is the surgeon's contribution to long-term survival in pancreatic cancer.

Pancreatic cancer has a poor prognosis with complete surgical resection being the only therapy to offer a realistic chance for long-term survival. The aim of this study is to identify surgery-related variables that influence long-term survival. Between 1990 and 2002, 226 consecutive patients (mean age of 64+/-11 years) had resection for pancreatic adenocarcinoma. Prognostic variables in these patients were analyzed using univariate and multivariate analysis. Two hundred four patients (90%) had pancreaticoduodenectomy, 13 patients (6%) had distal pancreatectomy, and 9 patients (4%) had a TP. Stage I disease was present in 50 (22%), stage II disease in 170 (75%), and stage III disease in 6 (3%). R0 resections were achieved in 70%. Operative morbidity was 36% and 30-day mortality was 6%. Actual 1-year, 3-year, and 5-year survival rates were 49% (n=111), 14% (n=31), and 4% (n=9). Using multivariate analysis: tumor size, tumor differentiation, obtaining an R0 resection, and lack of postoperative complications were variables associated with long-term survival. Long-term survival in patients with pancreatic cancer after resection remains poor. Achieving a margin negative resection (R0) with no postoperative complications are prognostic variables that can be affected by the surgeon.

[Per- and postoperative complications of TVT (tension-free vaginal tape)].

OBJECTIVES: Data concerning the complications of TVT are rare, incomplete and discordant. We therefore decided to record all intraoperative and postoperative complications of TVT observed in our experience and to evaluate these complications as a function of the patients and operators. MATERIAL AND METHOD: This was a single-centre retrospective study of 157 patients with a mean follow-up of 24 months (range: 5 to 50 months). We performed TVT either alone (76%) or associated with another pelvic surgical procedure (24%), especially simple vaginal hysterectomy (10%), and surgical repair of prolapse (14%). Some TVTs were performed in the presence of sphincter incompetence (32%) or mixed urinary incontinence (7%). The patient's history of pelvic surgery, vaginal surgery associated with TVT, the operator's experience, and the type of anaesthesia performed were assessed as risk factors for complications of TVT. RESULTS: The following complications were observed: bladder perforation (4.5%), urethral injury (0.6%), haemorrhagic dissection (5%), pelvic haematoma (0.6%), obturator nerve lesion (0.6%), suprapubic abscess (2%), urinary tract infection (7%), complete and lasting urinary retention (4%), expulsion of the TVT (2%), migration of the TVT (0.6%), de novo detrusor instability (1.5%). TVT was ineffective in 3% of patients. CONCLUSION: Although a global TVT complication rate of 28.4% in our series may seem high, it should be noted that these complications have a limited morbidity and usually have no consequences. Bladder perforation, haemorrhagic dissection, and urinary retention are the complications most frequently reported (4% to 5%). In this series, a history of pelvic surgery, an associated vaginal surgical procedure, and the operator's experience did not constitute risk factors for complication except in the case of haemorrhagic dissections; a history of pelvic surgery appeared to be a risk factor for intraoperative bleeding. In our experience, it is difficult to evaluate whether or not the type of anaesthesia performed for TVT increases the complication rate.

Prediction of postoperative complications after urgent laparotomy by intraperitoneal microdialysis: A pilot study.

OBJECTIVE: The aim of the present study was to investigate the role of intraperitoneal microdialysis (IPM) techniques in monitoring the evolution of postoperative critically ill patients requiring urgent laparotomy. SUMMARY BACKGROUND DATA: Postoperative intraabdominal sepsis is associated with an important degree of morbidity and mortality in acutely ill patients. Early diagnosis is critical to improve outcomes. METHODS: : The study included 25 consecutive patients admitted to the intensive care unit (ICU) after urgent laparotomy. Measurements of microdialysate fluid were performed through a microdialysis catheter, positioned intraperitoneally, during the first 5 postoperative days and lactate/pyruvate (L/P) ratios calculated. Patients were followed until hospital discharge. RESULTS: Ten patients had a complicated postoperative course, including 4 deaths (3 refractory shock, 1 mesenteric ischemia), 3 reinterventions (1 necrotic collection, 1 mesenteric ischemia, 1 biliary leak), 2 secondary peritonitis, and 1 intraabdominal collection. The IPM L/P ratio in these patients was already significantly higher during the first 24 postoperative hours compared with patients who had no complications (35 +/- 21 vs. 18 +/- 6, P < 0.01). An IPM L/P ratio above 22 on postoperative day 1 had a sensitivity of 0.64 and a specificity of 0.79 for complications. There were no significant differences between the two groups in pH, lactate, white blood cell count, or subcutaneous L/P ratio. No complication was associated with the technique. CONCLUSIONS: IPM is safe and reliable and provides valuable information after urgent laparotomy. Persistently high L/P values should raise the possibility of serious postoperative complications.

Tongue resection with the CO2 laser: the effects of past radiotherapy on postoperative complications.

A clinical study was undertaken in 21 patients to assess the effects of past radiotherapy on complications after tongue resection with the CO2 laser. Ten of the 11 irradiated patients experienced postoperative problems such as pain, haemorrhage, oedema, infection, delayed healing and poor function, while only one of the 10 non-irradiated patients had a problem due to minor bleeding after laser surgery. It is concluded that the CO2 laser is useful for primary excision of accessible tumours in the anterior tongue, but may be associated with more postoperative complications if the tongue has previously been irradiated. Where the tongue resection is part of a more radical excision, the CO2 laser is less advantageous.

[Stair climbing test in prediction of postoperative complications after lung cancer surgery].

Preoperative physical state of a patient is very important for adaptation of the patient after lung resections. Purpose of this work is to evaluate an information factor of a stair-climbing test while predicting of postoperative complications after lung cancer surgery. Fifty two patients were examined, who passed lung surgery of different volume. The patients are distributed to two groups: I(st) group included the patients able to climb 1-44 footsteps (n=22/42.3%) and the II(nd) group included the patients able to climb more than 44 footsteps at a moderate speed without stopping for rest (n=30/57.7%). One flight of stairs made up to 22 footsteps with 15 cm of height each. Postoperative myocardial ischemia, disorders of heart rhythm, pneumonias, atelectasis, prolonged artificial ventilation of lungs, sanative bronchoscopy, duration of treatment, and cases of death were registered. It was established that postoperative cardiac and lung complications occurred in 17 patients (32.7%), two patients died (3.8%). Rate of complications between the patients of the I(st) and II(nd) group was 82.4 ir 17.6 percent. Postoperative course was normal for those patients (n=11) who were able to climb five or more flights of stairs. It was noticed that duration of postoperative period has an inverse proportion to a number of the climbed up footsteps. The stair-climbing test is a simple, safe, cheap and informative enough for prediction of postoperative cardiopulmonary complications after lung cancer surgery.

Surgical and postoperative complications associated with tibial plateau leveling osteotomy in dogs with cranial cruciate ligament rupture: 397 cases (1998-2001).

OBJECTIVE: To identify surgical and postoperative complications of tibial plateau leveling osteotomy (TPLO) in dogs with rupture of the cranial cruciate ligament (CCL) and compare their incidence with those reported in the literature for other commonly performed CCL stabilization procedures. DESIGN: Retrospective study. ANIMALS: 346 dogs undergoing 397 TPLO procedures. PROCEDURE: Medical records of dogs undergoing 563 consecutive TPLO procedures were reviewed. Complications were recorded and assigned to groups on the basis of the period during which the complication was observed. RESULTS: 397 TPLOs met the criteria for inclusion in the study. Complications (n = 136) were recorded in 113 of the 397 (28%) procedures. Multiple complications developed in 10 dogs. In 19 dogs, a second surgery was performed to manage complications. Development of a complication after surgery was not associated with age or body weight of the dog, tibial plateau angle prior to stifle joint surgery, or experience of the surgeon. Factors significantly associated with complications were breed and performance of an arthrotomy concomitantly with TPLO. CONCLUSIONS AND CLINICAL RELEVANCE: TPLO was associated with development of numerous complications, some of which required surgical correction. Most complications resolved with nonsurgical treatment. Several complications were unique to the TPLO procedure because of the surgical technique and implants required. Although TPLO was associated with a greater number of complications than other CCL stabilization methods, the incidence of major complications was similar.

Perioperative and postoperative complications of intracavitary radiation for FIGO stage I-III carcinoma of the cervix.

PURPOSE: To evaluate perioperative and postoperative complications of low-dose-rate (LDR) intracavitary radiation therapy in patients with FIGO Stage I-III carcinoma of the uterine cervix. METHODS AND MATERIALS: We retrospectively reviewed the medical and radiotherapy records of all patients treated with radiation between 1960 and 1992 at The University of Texas M. D. Anderson Cancer Center for FIGO I-III carcinomas of the cervix. Patients who had had initial hysterectomy or whose treatment did not include intracavitary irradiation were excluded. The final study included 4043 patients who had undergone 7662 intracavitary procedures. RESULTS: Eleven (0. 3%) patients had documented or suspected cases of thromboembolism resulting in 4 deaths. Of these 11 patients, 8 had clinical or radiographic evidence of tumor involving pelvic nodes or fixed pelvic wall. The risk of postoperative thromboembolism did not decrease significantly with the routine use of mini-dose heparin prophylaxis (p = 0.3). Other life-threatening perioperative complications included myocardial infarction (1 death in 5 patients), cerebrovascular accident (2 patients), congestive heart failure or atrial fibrillation (3 patients), and halothane liver toxicity (2 deaths in 2 patients). Intraoperative complications included uterine perforation (2.8%) and vaginal laceration (0.3%), which occurred more frequently in patients >/= 60 years old (p < 0.01). Fourteen percent of patients had a temperature >/= 101 degrees F during at least one hospital stay. The only correlation between minor intraoperative complications and disease-specific survival was found in patients who had Stage III disease and uterine perforation; survival was significantly (p = 0.01) decreased in these patients. CONCLUSIONS: Fatal or life-threatening complications of intracavitary treatment were very rare. Deep venous thrombosis (DVT) and pulmonary embolism (PE) did not occur in otherwise healthy patients with early disease and were rare even when disease was more advanced. Minor perioperative complications were not correlated with serious late complications or with death from disease.

[Intra- and postoperative complications in surgery of the thyroid gland].

The authors studied the inter- and postoperative complications arising in a series of 690 consecutive interventions on thyroid. The results showed a cipher mortality and a 3% aggregate morbidity. In 0.9% of cases, compressive hematomata in the thyroid loggia, collapse of the tracheal wall due to tracheomalacia or bilateral paralysis of the vocal cords determined an acute respiratory stoppage. 1.4% of the treated patients suffered from alterations in the motility of the vocal cords, ascribable to damage of the recurrent nerves. 0.9% of cases showed a postoperative parathyroid insufficiency, the nature of which, however, was always temporary. The incidence of complications, in the whole, resulted significantly higher in the patients undergoing iterative surgery, in respect of those operated on the first time.
