Thigh isosulfan blue injection in the treatment of postoperative lymphatic complications.

Postoperative lymphatic complications after infrainguinal revascularization are troublesome and potentially serious complications. Vital dye injection into the web spaces of the foot has been recommended as a simple and reliable method to identify lymphatic channel disruption before groin exploration. Such distal injections, however, are not always successful. We describe a modified technique using a proximal thigh injection with isosulfan blue, which is faster and more useful than the distal web space method.

Laparoscopic Roux-en-Y gastric bypass: preoperative determinants of prolonged operative times, conversion to open gastric bypasses, and postoperative complications.

BACKGROUND: We examined our database of 600 consecutive laparoscopic Roux-en-Y gastric bypasses (LRYGBP) to determine predictors of prolonged operations, conversion to open operations and postoperative complications. METHODS: All were primary bariatric operations. Body habitus, gender, and previous surgery were evaluated. RESULTS: Regression analysis showed the following parameters to correlate positively with increased operative time: 1) Waist, 2) BMI, 3) Weight, and 4) Waist/Hip ratio. Height and hip measurement did not correlate with operative time. No previous operations affected operative time. Conversion to open operation was necessary in 25/600 cases (4.2%). Conversion was necessary with larger waist measurement (P=0.00007) and increased waist/hip ratio (P=0.01) but not BMI. Conversion occurred more frequently in males (6/43, 14.0%) than females (19/557, 3.4%). This trend was statistically significant (P=0.006). An enlarged liver was responsible for 12/25 conversions. 6/12 patients with large livers had type II diabetes and 6/12 patients had biopsy-proven steatohepatitis. 2/12 had huge yellow-brown livers that were not biopsed. Liver function tests were normal in 8/8 patients preoperatively. Complications including leak (5), pulmonary embolus (2), hemorrhage (12), stenosis of the GI tract (24) and infection (7) occurred in 48/600 patients (8.0%). There were no deaths. Complications did not correlate with body habitus, gender, or previous surgery. CONCLUSION: Larger patients as measured by waist measurement, weight, and BMI but not previous surgery prolonged LRYGBP. Conversion to open surgery was more frequently necessary in patients with larger abdomens, central obesity, and type II diabetes. Complications did not correlate with any preoperative parameter measured.

[Prevention of postoperative complications in vertebro-spinal cord pathology].

In 352 patients, affected by vertebral-medullary pathology, we evaluated the role played by the prevention or by the treatment of postoperative complications. We also evaluated their influence on the clinical outcome and neurological recovery. In every case we recorded a scrupulous post-operative neurological monitoring of the eventual complications, on the basis of the type, gravity and duration. From our results it appears that the complications, mostly secondary to infectious diseases, have an influence on the clinical and neurological recovery. We highlight the importance of an adequate nutritive management to prevent the complications, specifically those secondary to infectious diseases and cutaneous lesions.

[Prophylactics of postoperative complications in destructive appendicitis and typhlitis].

The method of extraperitonization of the blind gut cupola based on the removable monofilament sutures and drainage of the area was designed, approved in experiments in dogs (n=18) and corpses (n=14) and successfully applied in the clinic (n=25). Unlike the traditional method, the using of this one results in less impaired trophicity, LPO intensification and phospholipase activity of the tissues of regenerating structures that was the grounds of sufficiently rapid reparation process under conditions of inflammation. The proposed complex of surgical measures in patients with destructive forms of acute appendicitis complicated by the inflammatory-necrotic phenomena in the blind gut wall was shown to prevent the development of dangerous postoperative complications, incompetence of the sutures included.

The Gothenburg study of perioperative risk. I. Preoperative findings, postoperative complications.

The Gothenburg study of Perioperative Risk is a prospective clinical-epidemiological study designed to elucidate factors affecting the perioperative risk in unselected adult patients undergoing elective general or orthopaedic surgery. In this report reference data regarding preoperative characteristics and postoperative complications are presented. 1770 adult patients scheduled for elective general, urological, peripheral vascular or orthopaedic operative procedures were invited to a preoperative clinic. 81% agreed to participate and were assessed in a standardised way by means of questionnaires, interview, physical examination and laboratory screening. 82% had a previous or present condition in the medical history of some concern to the assessor. 71% had a finding of significance on physical examination. In 8% the assessment prompted further investigations or precautions. Throughout their hospital stay, all the 1361 participating patients were visited daily by an especially trained nurse with the task of registering the occurrence of complications. In 30% an untoward event occurred postoperatively--in 1% a severe one, in 21% a mild event, and in 8% an intermediate one. The complication rate was higher in vascular surgery (69%) than in orthopaedic (33%) and general/urological surgery (26%). Not only the severe and intermediate but also the mild complications affected the number of days in hospital.

[Postoperative complications and immediate results of reconstructive-plastic surgery of the trachea and bronchi].

For the last 3 years 77 reconstructive and plastic operations on the trachea and bronchi, including 25 pulmonectomies with tracheal bifurcation resection, were performed at the Chelyabinsk regional antituberculous dispensary. Postoperative complications were registered in 11.7% of the cases. Postoperative mortality (3.9%) is not associated with surgical complications. In 5 cases of left upper lobectomies with a circular resection of the primary bronchus, an original mobilization technique of the lower lobe of the left lung, enabling one to exclude the tension of an anastomosis and decrease the volume of hemithorax after resection, was applied. The rise in death from cancer and other diseases of the tracheobronchial tree with concurrent tuberculosis in some cases makes it advisable to widely integrate phthisiology and pneumology.

Postoperative complications of thyroidectomy for differentiated thyroid carcinoma.

OBJECTIVE: This study evaluates the incidence and risk factors of complications in patients submitted to thyroidectomy for differentiated thyroid carcinoma in a cancer hospital with residency training. STUDY DESIGN: A retrospective chart and complications review of 316 consecutive patients who underwent thyroidectomy for differentiated thyroid carcinoma. RESULTS: Of the 316 patients, the main postoperative complications were transient hypocalcemia in 87 (27.5%), permanent hypocalcemia in 16 (5.1%), transient vocal cord palsy in 4 (1.2%), and permanent vocal cord palsy in 2 (0.6%). Neck dissection and paratracheal lymph node dissection when associated with total thyroidectomy were significantly related to transitory and permanent hypocalcemia. CONCLUSION: Thyroid surgery can be performed safely in a hospital with medical residency training program under direct supervision of an experienced surgeon with acceptable morbidity. Hypocalcemia is the most significant complication. Neck and paratracheal lymph node dissections were the most significant predictors of hypocalcemia in patients submitted to total thyroidectomy.

Uvulopalatopharyngoplasty: evaluation of postoperative complications, sequelae, and results.

A study of 71 patients with obstructive sleep apnea syndrome was performed to evaluate the effectiveness, complications, and late sequelae of uvulopalatopharyngoplasty. Postoperative immediate complications were of minor importance. In 96% of the patients, the snoring was improved; it was completely resolved in 48%. The postoperative apnea index remained pathologic in all patients who underwent postoperative polysomnography, although mild improvement was noted. Seventy-four percent of our patients felt a subjective postoperative improvement which was not always confirmed by the polysomnographic examination. A record of improvement was obtained in 64% of the operated patients. Our results establish the beneficial effect of uvulopalatopharyngoplasty, which is the recommended surgical procedure for obstructive sleep apnea syndrome.

Anesthesia related hypoxemia. The effect of pulse oximetry monitoring on perioperative events and postoperative complications.

The objectives of the present investigation were to evaluate the extent of perioperative hypoxemia and to investigate the impact of pulse oximetry monitoring on the extent of hypoxemia and on perioperative morbidity in adults. To accomplish these objectives a number of prospective studies were carried out. The incidence, duration, and severity of hypoxemia were evaluated in two single blinded observer studies in the operating room (N = 296) (I) and in the Postanesthesia Care Unit (N = 200) (II). Pulse oximetry monitoring's effect on the extent of hypoxemia was evaluated in a randomized blinded observer study of 200 patients (III). The impact of pulse oximetry on the frequency of perioperative events, changes in patient care, and post-operative complications were studied in a randomized evaluation of 20,802 patients (IV-V). Finally, a subgroup of 736 patients already included in the randomized evaluation was psychologically evaluated pre- and postoperatively (VI). In the observer studies in the OR and PACU mild hypoxemia (SpO2 86-90%) was recorded in 53% and 55% of the patients, respectively. Severe hypoxemia with SpO2 values < 81% was recorded in 20% and 13% of the patients, respectively. In the randomized blinded observer study, patients with pulse oximeter data available had a significantly reduced incidence of perioperative hypoxemia when compared to patients where the data were unavailable. Most noteworthy was that in the available group extreme hypoxemia (SpO2 < 76%) was not encountered in the OR and both severe (SpO2 76-80%) and extreme hypoxemia were not observed in the PACU. In the randomized evaluation of pulse oximetry significantly more patients in the oximetry group experienced at least one respiratory event than did control patients in both the OR and in the PACU. This was a result of a 19 fold increase in the incidence of diagnosed hypoxemia in the oximetry group than in the control group. In the OR cardiovascular events were observed in a similar number of patients in both groups, except myocardial ischemia, which was detected in 12 patients in the oximetry group and in 26 patients in the control group (P < 0.03). Several changes in PACU care were observed in association with the use of pulse oximetry. These included higher flow rates of supplemental oxygen (P < 0.00001), increased use of supplemental oxygen at discharge (P < 0.00001), and increased use of naloxone (P < 0.02). One or more postoperative complications occurred in 10% of the patients in the oximetry group and in 9.4% in the control group (NS).(ABSTRACT TRUNCATED AT 400 WORDS)

Determinants of hospital charges for coronary artery bypass surgery: the economic consequences of postoperative complications.

This is a prospective study of 500 consecutive patients having coronary artery bypass surgery; mean hospital charge from time of surgery to discharge was +11,900 +/- 12,700. Multiple regression analysis was performed using preoperative variables and postoperative complications. No preoperative clinical feature was a significant predictor of higher average charge. Sternal wound infection (p = 0.0001), respiratory failure (p = 0.0001) and left ventricular failure (p = 0.017) were associated with higher average hospital charge. The absence of any complication predicted a lower average charge, and postoperative death (4.4 +/- 4.5 days after surgery) was also associated with lower average charge. A cost equation was developed: hospital charge equalled $11,217 + $41,559 of sternal wound infection, + $28,756 for respiratory failure, + $5,186 for left ventricular failure, - $1,798 for no complication and - $6,019 for death. Recognition of the influence of complications on charges suggests that low average charges can only be achieved by surgical programs with a low complication rate.

Postoperative complications after pneumonectomy for treatment of lung cancer: multivariate analysis.

The charts of 62 patients with primary lung cancer who underwent a pneumonectomy at our department from 1979 through 1992 were reviewed for the evaluation of postoperative morbidity and mortality. The 30-day mortality was 3/62 or 4.8%. Postoperative complication occurred in 37 of 62 patients (60%). The most common complication was a supraventricular tachyarrythmia. A major complication, which was defined as one necessitating re-thoracotomy or one which caused death, occurred in 19 patients (31%). We analyzed 43 perioperative variables for their predictive value of postoperative morbidity and mortality. Univariate analysis indicated that an elevated serum LDH, low predicted forced vital capacity, low predicted forced expiratory volume in 1 sec (FEV1) were significantly associated with the occurrence of a major complication. A multivariate logistic regression model indicated that a high LDH level, a low predicted FEV1 and no extubation following surgery were associated independently with a postoperative major complication. Since only the complete removal of a tumor offers a chance for cure for the treatment of non-small cell lung cancer, it is sometimes necessary to perform a pneumonectomy for these high-risk patients. Patients identified as being at high risk of a major complication should be candidates for intensive preoperative evaluation and perioperative care.

Inhibition of pancreatic secretion to prevent postoperative complications following pancreatic resection.

Major pancreatic resection still nowadays carries a considerable risk for morbidity and even mortality. Complications occurring after pancreatic surgery are chiefly linked with exocrine pancreatic secretion. Therefore to inhibit exocrine pancreatic secretion perioperatively, seems to be a promising concept in the prevention of complications following pancreatic resection. The hormone somatostatin and its synthetic analogue octreotide have been demonstrated to inhibit exocrine pancreatic secretion profoundly, particularly the secretion of proteases is decreased. In a randomized placebo-controlled multicentric and double blind trial we analysed the role of octreotide in the prevention of postoperative complications after major pancreatic surgery. A significant reduction of complications (fistula, abscess, fluid collection, sepsis, pulmonary insufficiency, postoperative acute pancreatitis) could be demonstrated in patients receiving octreotide (3 x 100 micrograms per day sc.). The effect of octreotide was particularly true in patients undergoing a Whipple resection for cancer.

[Mild intraoperative hypothermia. Another risk factor for postoperative complications].

Intraoperative mild hypothermia (core temperature 35-36 degrees) is common during major surgical procedures. Recent studies have shown that hypothermia may be related to the development of postoperative serious complications such as impaired platelet function with increased blood loss and transfusion requirements, postoperative morbid cardiac events, impaired wound healing, and prolonged hospitalization. Core hypothermia during surgery should therefore receive more attention as a risk factor for postoperative complications. The most effective prevention of intraoperative hypothermia is forced air warming combined with the infusion of warm fluids. The paper gives clinical guidelines for monitoring and prevention of intraoperative core hypothermia.

[Per- and postoperative complications of surgical treatment of lumbar spinal stenosis. Prospective study of 306 patients].

PURPOSE OF THE STUDY: The main objective of this prospective observational study of a consecutive series of patients was to determine the rate of per- and postoperative complications of surgical treatment of lumbar spinal stenosis. A second objective was to describe these complications and search for factors favoring their occurrence. MATERIAL AND METHODS: All patients who underwent surgical treatment of spinal stenosis without significant spinal deviation in our unit between January 1998 and January 2000 were enrolled in this study. The series thus included 306 patients with at least six months follow-up. Three types of data were recorded before surgery: demographic data including comorbidity, data related to the type of stenosis operated, and data related to the type of procedure (simple release, release with fusion, etc.). A special observation chart was designed to record all complications during the hospital stay and follow-up visits at three, six and twelve months. Four categories of complications were recorded: general complications, early or late infections, early or late mechanical disorders, and neurological complications including meningeal involvement and surgery-related neurological disorders. Univariate analysis was performed to determine the overall rate of complications and the incidence within each category of complications. Multivariate analysis using logistic regression was performed to examine factors favoring occurrence of complications. RESULTS: The overall rate of complications was 26.5%. The incidence of general, infectious, neurological, and mechanical complications was 13, 4.5, 2.6 and 2% respectively. The incidence of serious complications and/or events requiring reoperation was 12%. Comorbidity, body mass index, operative time, and reoperation were found to favor the occurrence of complications. DISCUSSION AND CONCLUSION: The rates of complications reported in the literature have varied greatly. Most have been calculated from retrospective series, making it difficult to compare them with our results. Our work emphasizes the importance of certain favoring factors which should be re-examined in a larger series.

Fall in diffusing capacity associated with induction therapy for lung cancer: a predictor of postoperative complication?

BACKGROUND: Pulmonary resection after induction therapy is associated with high rates of pulmonary morbidity and mortality. However, the impact of induction therapy on the pulmonary toxicity and associated pulmonary complications has not been fully investigated in the setting of lung cancer surgery. METHODS: We assessed the 66 consecutive patients who underwent a pulmonary resection after induction therapy, 48 of whom received chemoradiotherapy and 18, chemotherapy alone. Results of pulmonary function before and after induction therapy were compared, and logistic regression analyses utilized to explore the risk factors of pulmonary morbidity. RESULTS: After induction therapy, forced expiratory volume in 1 second (FEV1) was increased significantly (from 2.28 +/- 0.61 L to 2.40 +/- 0.62 L; p < 0.05); however, percent vital capacity (%VC) and FEV1/FVC did not change significantly. The diffusing capacity of lung for carbon monoxide (D(LCO)) was decreased significantly by 21% (from 90.3% +/- 18.3% to 71.1% +/- 12.5%; p < 0.0005). Patients with respiratory complication showed lower predicted postoperative %FEV1 (49.5% +/- 11.1% versus 57.2% +/- 14.2%; p = 0.031) and predicted postoperative %Dlco (41.9% +/- 8.0% versus 55.4% +/- 10.1%; p < 0.0001) results than those without complications. Univariate and multivariate analyses revealed that predicted postoperative %D(LCO) alone was an independent factor to predict postoperative pulmonary morbidity. CONCLUSIONS: For patients who undergo a pulmonary resection after induction therapy, predicted postoperative %D(LCO) is more important to predict pulmonary morbidity rather than static pulmonary function (predicted postoperative %VC or %FEV1). The decrease in D(LCO) is thought to reflect a limited gas exchange reserve, caused by the potential toxicity of chemotherapy or chemoradiotherapy. We believe that the impact of diffusion limitation after induction therapy should to be emphasized to decrease the pulmonary morbidity.

[Pedicled facial bone flap for closure of the approach in Caldwell-Luc type sinus operations. Its role in the prevention of postoperative complications].

The primary or secondary reconstruction of the facial access after Caldwell-Luc and the more selective resection of sinusal mucous membranes can be important in the therapy and prevention of postoperative complications such as neuralgic facial pain, formation of cysts and chronic sinusitis. The different osteoplastic sinus operations are described and the use of a pedicled bonelid is illustrated. The most common accepted ethiology of post-operative pain is based on the formation of scar-tissue. Postoperative pain is first being treated conservatively, while in case of persisting pain an exploration with dissection of the infra-orbital nerve and reconstruction of the facial defect can be indicated. In a retrospective study of 36 patients the results of our surgical therapy are illustrated.
