Laser-assisted uvulopalatoplasty: postoperative complications.

Laser-assisted uvulopalatoplasty (LAUP) has become a widely used procedure for the treatment of snoring and mild sleep apnea in the United States. Between July 1993 and December 1994, the authors of this study prospectively evaluated 541 consecutive patients referred to their hospital for possible LAUP to treat loud disruptive snoring. Of the 541 patients, 275 patients had a total of 754 LAUP procedures. There were 26 complications (3.45%). These complications included postoperative hemorrhage in 16 patients (2.12%), local infection in 4 patients (0.53%), temporary palatal incompetence in 4 patients (0.53% , and temporary loss of taste in 2 patients (0.27%). None of the 16 patients with postoperative hemorrhage required a blood transfusion. Only 10 patients (1.3%) had hemorrhage that required medical attention; in the other patients, the bleeding stopped spontaneously. There were no cases of hypernasal speech, permanent palatal incompetence, nasopharyngeal stenosis, airway compromise, or death.

Poor prognosis in esophageal cancer patients with postoperative complications.

We investigated the relationship between postoperative complications and prognosis in esophageal cancer patients. Two hundred five patients with esophageal cancer were divided into three case groups. Group A (n = 100) consisted of cases without postoperative complications. Groups B (n = 58) and C (n = 47) consisted of cases with minor and major postoperative complications. The 5-year survival rates were 41.8%, 21.3%, and 20.2% in groups A, B, and C, respectively. There was a significant difference in the prognosis between groups A and B, and also between groups A and C. Any patients who died within 5 years without a relapse their cases were excluded from the study; the 5-year survival rates were 46.7%, 32.3%, and 22.5% in groups A, B, and C, respectively, with a significant difference between groups A and B. There were no significant differences between the three groups regarding the patient characteristics. These results therefore indicate that postoperative complications might contribute to a poor prognosis in cancer patients.

Postoperative complications of elective surgeries in dogs and cats determined by examining electronic and paper medical records.

Postoperative complications (POC) that developed in dogs and cats that underwent elective ovariohysterectomy, castration, and declaw at a veterinary teaching hospital were determined by examining the computerized abstracts of the medical records and by examining a random sample of the paper medical records. When the computerized abstracts were examined, POC were found to have occurred in 62 (6.1%) of 1,016 dogs. One dog died and 6 others developed major complications. Postoperative complications were found to have occurred in 38 (2.6%) of 1,459 cats. Two cats died and 1 was euthanatized. Four other cats developed major complications. Complete paper medical records for 218 dogs and cats were examined. When the paper medical records were examined, the proportions of dogs and cats with POC were 19.4% and 12.2%, respectively. These proportions were 4 to 7 times higher than when the computerized abstracts were the data source. Results of this study indicate that the frequency of clinically relevant POC of elective surgeries in dogs and cats is substantial. Examination of the computerized abstracts of medical records at this hospital allowed us to rapidly identify cases that could be included in the study but the frequency of POC would be significantly underestimated if paper records were not also assessed.

Equine surgical colic: risk factors for postoperative complications.

The reason for undertaking this study was that postoperative complications of colic surgery lead to patient discomfort, prolonged hospitalisation and increased cost. Potential risk factors for the 6 most common postoperative complications (jugular thrombosis, ileus, re-laparotomy, wound suppuration, incisional herniation and colic) were evaluated using multivariable models. Jugular thrombosis was associated significantly with heart rate greater than 60 beats/min and with increased packed cell volume (PCV) at admission. The risk of postoperative ileus also increased with increasing PCV at admission and was higher in horses recovering from pedunculated lipoma obstruction. Incisional herniation was strongly associated with wound suppuration and with increasing heart rate at admission. The emergence of cardiovascular parameters as risk factors for several postoperative complications is consistent with the hypothesis that endotoxaemia is important in the development of these complications. Early referral of colic cases, prior to the development of severe endotoxaemic shock, may minimise the risk of some postoperative complications. Horses that have suffered epiploic foramen entrapment, are more than 4 times as likely to undergo re-laparotomy than other horses. Horses that have suffered postoperative ileus have a similarly increased risk of undergoing re-laparotomy. The risk of postoperative colic is significantly associated with horses recovering from large colon torsion (>360 degrees) and with having undergone re-laparotomy. Hazard ratios (with 95% confidence intervals) for these last two effects are 3.1 (1.7, 5.7) and 3.4 (1.9, 6.2), respectively. Knowledge of the risk factors for postoperative complications allows more accurate prognostication postoperatively and suggests ways in which the risk of postoperative complications can be minimised.

[Postoperative complications and treatments after Bentall operation].

Postoperative complications of Bentall operation for the annuloaortic ectasia have frequently occurred, although the mortality has been reduced. To reduce complications after Bentall operation we have taken three major treatments since 1987. The first was reimplantation technique of coronary ostia in replacing the ascending aorta and the aortic valve with a tube graft. The second was the infusion technique of cardioplegic solution such as retrograde cardioplegia infusion. The third method was to save blood and reduce the blood transfusion by preserving autoblood preoperatively and using cell saving machine. The purpose of this study was to analyse 20 patients who underwent the Bentall procedure and to investigate the effect of our treatments in Bentall operation on the operative results. We divided our patients into two groups. Fourteen patients in the group 1 were operated before 1987, when our principles were not performed. Six patients in group II were operated under the principles mentioned above. There were no differences in cardiopulmonary bypass time and ischemic time between group I and II. Transfused blood volume in group II was remarkably less than that of group I. Postoperative complications occurred in all patients in group I (100%), while three patients in group II (50%) had complications (p less than 0.05). We, hence, conclude that our method could be useful for reducing postoperative complication rate in Bentall operation.

Relation of anthropometric and dynamometric variables to serious postoperative complications.

Prediction of serious postoperative complications by using standard anthropometric and biochemical nutritional variables was attempted in 225 patients admitted for major abdominal surgery. In 102 of the patients hand-grip dynamometry was also measured, and this proved the most sensitive test, predicting complications in 48 of the 55 patients (87%) who developed them (p < 0.001). Arm muscle circumference and forearm muscle circumference below 85% of the standard value were also of predictive value (p < 0.02 and p < 0.01 respectively); weight for height and serum albumin concentrations were less satisfactory, while weight loss of more than 10% was not significantly related to complications. Dynamometry is a useful, rapid, and inexpensive screening test for detecting malnutrition that is likely to predispose to serious postoperative morbidity.

[Follow-up of patients who underwent reduction mammoplasty according to Strombeck between 1972 and 1975. Postoperative complications and results. Modification of the technique. Postoperative mammographic results (author's transl)].

Follow-up examinations were carried out in 60 women who underwent a reduction mammoplasty. Their review concentrated on the questions of the frequency of postoperative complications, the possibility to avoid complications by a modification of the technique and the question of mammographic evaluation of the breast in the face of scars from the mammoplasty. There were 12 severe complications. There were 6 necroses of the nipples, there were 3 abscesses, there were 2 suture fistulas and there was one case of massive hematoma. The complications depend on the amount of tissue resected. Especially necroses of the nipples depend upon the amount of tissue resected. With increasing experience of the surgeon, the nipple is moved without tension by lateral division of tissues and omission of resection of tissue above the nipple. This reduces the risk of necrosis of the nipple. Ugly scars are avoided by additional subcutaneous dexon double O sutures and additional subcuticular structures. Prolonged immobilization and later removal of the sutures help to obtain fine scars. A comparison of the preoperative and postoperative mammographies showed that 78% of the X-rays could be evaluated for carcinoma more readily postoperatively than before. For the differential diagnosis to scars from the operative, a preoperative and postoperative mammogram is necessary for comparison.

[Does a one-time colonic or rectal resection without protective colostomy increase the rate of postoperative complications?].

The rate of postoperative complications is the decisive criterion in evaluating the preoperative preparation of the large intestine, the operative methods, and the technique of anastomosis. Preparations for colorectal surgery include administration of antibiotics and the use of a three-row suture method of anastomosis without the protection of an intestinal fistula. The results of 1054 colorectal resections are promising: The rate of anastomotic insufficiency was 3.9% after resection of tumors and 4.9% after resection of inflamed diverticula. Lethality from local causes was 1.2% and 1.9%, respectively. Disturbance of wound healing occurred in 10.7% of the cases.

Ruptured aortic aneurysms: postoperative complications and their management.

Postoperative complications in 92 patients undergoing repair of ruptured abdominal aortic aneurysms are reviewed. Renal failure and cardiac complications were fatal in 74% and 85% of the patients, respectively. Preoperative renal function at the time of presentation had no correlation with the development of renal failure. All but one patient in whom the left renal vein was divided developed renal failure postoperatively. There also was a preponderance of this complication in the patients needing suprarenal aortic control. Respiratory complications were seen in 29% of patients with 22% mortality. Peripheral emboli and ischemic colitis developed in 8% and 9% of the patients, respectively.

[Early postoperative complications of choledochal cyst excision and reconstruction of biliary tract].

OBJECTIVE: To study the early postoperative complications of choledochal cyst excision with reconstruction of the biliary tract. METHODS: In last 10 years, 173 patients aged from 27 days to 14 years (mean = 2.4 years) were operated on with procedures of choledochal cyst excision and biliary tract reconstruction by jejunointerposition between the liver hilum and duodenum or Roux-en-Y hepaticojejunostomy in our hospital. Amongst these 173 patients, 16 were found to suffer from postoperative complications. Therefore, their clinical data were retrospectively analyzed, and the prevention and treatment of the early postoperative complications discussed. RESULTS: The morbidity of early postoperative complications was 9.3% (16/173). The early complications included biliary leakage in 10 patients, wound dehiscence of abdominal wall in 3, hepatic failure in 1, pancreatic fistula in 1, and postoperative enteric intussusception in 1. The morbidity of early postoperative complications in infants younger than 1-year old was significantly higher than that in children(chi 2 = 15.78, P < 0.01). However, there was no significant difference in the morbidity of early postoperative complications between patients undergoing biliary tract reconstruction by jejunal segment interposition and those undergoing that by Roux-en-Y hepaticojejunostomy (chi 2 = 0.07, P > 0.05). The total mortality in all the operated patients was 2.3% (4/173). Three patients died from biliary leakage and 1 from postoperative hepatic failure. CONCLUSIONS: Biliary leakage, wound dehiscence of abdominal wall and hepatic failure are major early postoperative complications. The morbidity in infants younger than 1-year old is higher than in children. The preoperative treatment of biliary tract infection, hypohepatia, and surgical skills during operation should be emphasized. Reoperation for biliary leakage should not be delayed and mycotic cholangitis after biliary leakage needs more attention. Tension suture in the fascial space of the abdominal wall is useful for the prevention and treatment of abdominal wall dehiscence.

Complications of vitreous surgery for diabetic retinopathy. II. Postoperative complications.

One hundred seventy-nine eyes were analyzed to determine the incidence of postoperative complications after vitrectomy for proliferative diabetic retinopathy. One hundred twenty-nine (72%) of the 179 eyes achieved improved vision, and 117 (65%) were considered visual successes with final vision in the functional range of 5/200 or better. Corneal epithelial defects occurred in 51 eyes (28%), but severe corneal complications were rare, and no eye developed corneal clouding as the sole cause of later visual loss. The lens was retained in 128 eyes (75%), and visually significant lens opacities occurred later in 17% of the phakic eyes. Postoperative iris neovascularization was reduced by not removing the lens, and rubeosis iridis occurred in 15 (13%) of 114 phakic eyes and in 21 (32%) of 65 aphakic eyes (P = 0.012). Vitreous hemorrhage was present in 75% of eyes immediately after surgery and cleared in an average of 6.2 weeks in phakic eyes and 5.4 weeks in aphakic eyes. Fifty-two eyes (29%) had recurrent vitreous hemorrhage after the initial postoperative period. New retinal detachment occurred after surgery in 16% of eyes and was treated successfully in 38%. Reoperations were done in 45 eyes (25%), and 32 (71%) of these were for repair of retinal detachment or removal of nonclearing vitreous hemorrhage. Six eyes (3%) developed phthisis bulbi, and one other eye was enucleated.

Postoperative altered plasma growth hormone levels--a predictor for postoperative complications? A case report.

We compared the onset of predictors for postoperative complications (lactate, total T2 (tT2), total T4 (tT4) and cortisone) retrospectively with the onset of altered growth hormone (GH) concentration in a patient who had had a lethal postoperative outcome and in 13 patients who were without postoperative complications for a period of 24 hours postoperatively. Compared with the values of the patients without postoperative complications, GH values were elevated (68-fold) 1 h after surgery to 103 ng/ml and lactate was increased (12-fold) to 12.7 mmol/l at 6 h postoperatively in the patient with the lethal outcome. The other parameters measured (tT3, tT4 and cortisone) showed no rapid alteration during the first hours postoperatively. This case report suggests that the rapid postoperative onset of raised GH concentration in plasma may be an earlier marker for postoperative complications than the 'established' predictors.

[Lung scintigraphy and ergospirometry in prediction of postoperative course in lung resection candidates with increased risk of postoperative complications].

Patients with impaired pulmonary function are at increased risk for the development of postoperative complications. We therefore analyzed the value of preoperative lung scanning and exercise testing for the prediction of postoperative complications and of the short- as well as long-term performance in lung resection candidates at increased risk for complications. Twenty-five (mean age 63 y; 17 m) out of 84 consecutive lung resection candidates were considered at increased risk for postoperative complications due to impaired pulmonary function (FEV1 < 2L or diffusion for carbon monoxide (DLCO) < 50% predicted, or FEV1 and DLCO < or = 80% predicted combined with New York Heart Association dyspnea index > or = 2). Candidates underwent radionuclide perfusion scans and exercise testing to predict postoperative ( = ppo) values for FEV1, DLCO and maximal O2-uptake (VO2max). They all underwent thoracotomy for neoplastic lesions; 7 had pneumonectomies, 18 lobectomies. Six had postoperative complications (within 30 days), of whom three died. Three and 6 months postoperatively, pulmonary function tests and VO2max were repeated. In the 22 survivors, the observed values were then compared with the predicted values. At 3 months, there were excellent correlations (absolute/predicted values): for FEV1r = 0.78 and 0.81; for DLCOr = 0.77 and 0.74; and for VO2max r = 0.71 and 0.83. The means of FEV1 and VO2max did not differ from the predicted values, whereas the predicted DLCO was lower than the observed value (ml/min/mmHg: 15.1 vs 17.9; percent predicted: 59.6 vs 70.9) (p < 0.05). At 6 months, correlations remained very good for FEV1 (r = 0.81 and 0.84) and for DLCO (r = 0.76 and 0.74), but had decreased for VO2max to 0.56 and 0.65, respectively. All means were higher than predicted (p < 0.05) owing to recovery in the lobectomy group. Patients with postoperative complications (group B) had a lower preoperative VO2max in percent predicted (62.8 +/- 7.5% vs 84.6 +/- 19.7%) (p < 0.01) and also a lower VO2max-ppo (10.6 +/- 3.6 vs 14.8 +/- 3.5 ml/kg/min and 44.3 +/- 13.5 vs 68.0 +/- 20.7 percent predicted) (p < 0.05) than patients without complication (group A). AVO2max-ppo < 10/ml/kg/min was associated with a 100% mortality. Although FEV1-ppo and DLco-ppo were lower in group B the difference did not reach significance. We conclude that radionuclide-based calculations of postoperative VO2max are predictive of perioperative morbidity and mortality: a VO2max-ppo of < 10 ml/kg/min may indicate inoperability. Further, short-term postoperative performance is accurately predicted by FEV1-ppo and VO2max-ppo, but long-term function is underestimated after lobectomy.

[Orthopaedic one day surgery: anaesthesiologic techniques used and intra- and postoperative complications].

OBJECTIVE: Optimize patient management in one day surgery (ODS) by an observative study regarding one day orthopaedic surgery, assessing kind and quantity of intra- and postoperative complications, need for prolonged postoperative assistance postponing discharge, recovery in other hospitals, patients satisfaction index. METHODS: From september 1999 until december 2000 we distributed a questionnaire 1286 consecutive patients. The patients were ASA I (80,7%), ASA II (17%) and ASA III (2,3%). We evaluated intra- and postoperative complications considering type of surgery and anaesthesiologic technique; need and reason for medical consulting; if consulting took place in other institutes. Patients judgement regarding medical and nursing assistance during in hospital stay was assessed. RESULTS: Main surgical procedures: arthroscopy (44,6%), internal fixation removal (21,3%), neurolysis (9,5%), cysts/tumours/nodules removal (7,5%), foot surgery (8,0%). Used anaesthesiologic techniques: neural block (65,6%), plexus block (15,1%), general (12,5%), spinal (4,8%) and local anaesthesia (1,9%). An intraoperative complication (convulsion) was reported twice. Postoperative complications: pain (3,6%) most frequent in foot surgery (5,2%), nausea (0,2%), fever (0,7%), haematoma (0,5%). 5 delayed discharges (beyond 24h) were reported, for surgical reasons. In 5 cases another institute was visited. There were no deads. CONCLUSIONS: The percentage of not planned recoveries (0,1%) is an indication of frequency of major complications. Satisfaction index of patients was high (96%). Kind of surgical procedure and anaesthesiologic technique, considering the minimal intra- and postoperative complications, are adjusted to the ODS regime. Reinforcing analgesic protocols in foot surgery though are necessary. According to our opinion the peripheral block is preferable in orthopaedic ODS.

Silicone oil removal. II. Operative and postoperative complications.

A retrospective study of the effects of silicone oil removal was carried out on 85 patients who had undergone pars plana vitrectomy and silicone oil exchange for giant retinal tears or proliferative vitreoretinopathy. Silicone oil was removed either as part of the treatment of anterior segment complications such as glaucoma and keratopathy (25 patients) or in order to prevent these complications (60 patients). The major complications of the removal of silicone oil were retinal redetachment (25%), hypotony (16%), and expulsive haemorrhage (1%). The length of time that the oil remained in the eye and the presence of anterior segment complications did not appear to have an effect on the rate of retinal redetachment or hypotony.
