A retrospective evaluation of the rectal pull-through technique. Procedure and postoperative complications.
Ten animals (8 dogs and 2 cats) with distal rectal lesions were treated by surgically resecting the affected segment of the rectum by the rectal pull-through technique. There were four malignant tumors, three benign tumors, two inflammatory lesions, and one malignant tumor that extended histologically to the margins of a previous surgical excision. Postoperative complications were tenesmus (7 animals), fecal incontinence (4 animals), rectal bleeding (4 animals), and abscess formation (1 animal). Dehiscence and stricture were not observed. The four animals with malignant tumors survived less than 12 months after surgery. One of the four animals still living has persistent fecal incontinence. The rectal pull-through technique is described and illustrated.

Ruptured aortic aneurysms: postoperative complications and their aetiology.
A review of 198 ruptured aortic aneurysms has been undertaken, this being 36.3 per cent of all the aneurysms treated during the period 1960-81. The overall mortality rate was 42.9 per cent. The peroperative mortality was 6.6 per cent and the mortality of the patients who survived the operation was 38.9 per cent. Factors which influenced postoperative mortality were the age of the patient, the distance travelled to hospital, the presence of an intraperitoneal bleed, the duration of the operative procedure and the volume of blood transfused, but only the amount of blood transfused had a statistically significant influence on mortality. However, as the highest mortality associated with any of these risk factors was 54.9 per cent, no single factor alone can be considered a contra-indication to operation. As there are no reliable predictive factors, we believe that all cases with clinically ruptured aortic aneurysms should have a laparotomy and resection. The most common postoperative complications were varying degrees of renal and respiratory insufficiency and the occurrence of these was significantly associated with the volume of blood transfused.

Resective surgery for liver tumor: a multivariate analysis of causes and risk factors linked to postoperative complications.
BACKGROUND: In spite of accurate selection of patients eligible for resection, and although advances in surgical techniques and perioperative management have greatly contributed to reducing the rate of perioperative deaths, stress must be placed on reducing the postoperative complication rates reported to be still as high as 50%. This study was designed to analyze the causes and foreseeable risk factors linked to postoperative morbidity on the grounds of data derived from a single-center surgical population. METHODS: From September 1989 to March 2005, 287 consecutive patients, affected either with HCC or liver metastasis, had liver resection at our department. Among the HCC series we recorded 98 patients (73.2%) in Child-Pugh class A, 32 (23.8%) in class B and 4 in class C (3%). In 104 colorectal metastases, 71% were due to colon cancer, 25% rectal, 3% sigmoid, and 1% anorectal. In 49 non-colorectal metastases, 22.4% were derived from breast cancer, 63.2% gastrointestinal tumors (excluding colon) and 14.4% other cancers. We performed 80 wedge resections, 77 bisegmentectomies and/or left lobectomies, 74 segmentectomies, 22 major hepatectomies, 20 left hepatectomies, and 14 trisegmentectomies. RESULTS: The in-hospital mortality rate in this series was 4.5%, and the morbidity rate was 47.7%, because of pleural effusion (30%), hepatic abscess (25%), hepatic insufficiency (19%), ascites (10%), hemoperitoneum (10%), or biliary fistula (6%). The variables associated with the technical aspects of the surgical procedure that were responsible for the complications were: a Pringle maneuver length more than 20 minutes (P=0.001); the type of liver resection procedure, including major hepatectomy (P=0.02), left hepatectomy (P=0.04), trisegmentectomy (P=0.04), bisegmentectomy and/or left lobectomy (P=0.04); and a blood transfusion of more than 600 ml (P=0.04). CONCLUSION: The evaluation of causes and foreseeable risk factors linked to postoperative morbidity during the planning of surgical treatment should play the same role as other factors weighed in the selection of patients eligible for liver resection.

Are postoperative complications related to resident sleep deprivation?
This real-world study compares the outcome of surgery and the sleep-deprivation status of the resident surgeon. Residents who operated the day after a 24-hour on-call period were considered sleep deprived; all other resident surgeons were considered non-sleep-deprived. We retrospectively reviewed data on 6,371 surgical cases and identified 351 postoperative complications. The complication data were analyzed using logistic regression analysis, with outcome being the presence or absence of surgical complications. No statistically significant change in complication incidence was noted when the resident surgeon was sleep deprived.

[Index for a pulmonary postoperative complication after upper abdominal surgery: a validation study].
OBJECTIVE: To validate a previous prognostic index (Pereira et al.) to postoperative pulmonary complication in elective upper abdominal surgery, and observe the risk factor for mortality in this population. METHODS: 283 patients were followed from pre to postoperative period. They were followed in a protocol including a clinical questionnaire, physical examination, thoracic radiogram and spirometry at pre operative period. The main variables measured were: clinical and functional subjects characteristics at pre operative, type of surgery, duration of surgery, time spent in intensive care unit and hospitalization and the occurrence of pulmonary complication. RESULTS: 69 patients had pulmonary complications (24.4%), in 87 events registered. These occurred because some patients had more than one complication. Pneumonia was the most freqüent event 34% (30/87) followed by atelectasis 24% (21/87), bronchoconstriction 17% (15/87), acute respiratory failure 13% (11/87), prolonged mechanical ventilation 9% (8/87) and bronchial infection 2% (2/87). The multiple logistic regression (MLR) showed the association between age above 56 years old (p = 0.0039); DS > 210 (p = 0.0044) and previous chronic pneumopathy (p = 0.0257) and postoperative pulmonary complication. The frequency of postoperative pulmonary complication observed in each categorical classis based on previous index (Pereira equation) did not differ statistically from the prognostic rate calculated, showing the validity of the prognostic index. When FEV1/FVC was included in MLR, the patients with VEF1/FVC<70% and DS> 210 minutes showed a statistically lower number of pulmonary postoperative compared with estimated by the previous Pereira index. The mortality analyses showed significant association with comorbidity, number of days in care unit and postoperative pulmonary complication, however in the MLR only postoperative pulmonary complication had a significant association with death (p = 0.003). CONCLUSIONS: The index based on Pereira equation is valid to estimate the prognosis of postoperative pulmonary complication after elective upper abdominal surgery. Age higher 56 years old, duration of surgery more than 210 minutes and pneumopathy are important markers of postoperative pulmonary complication. The only significant marker for mortality was the post operative pulmonary complication.

Postoperative complications: how much do they cost?
Complications following major abdominal surgery incur considerable expense. The aims of this study were to analyse prospectively the costs of complications following major abdominal surgery and to compare such costs with those of elective distal large bowel resection. Six patients undergoing elective resection for large bowel cancer were studied at the Royal South Hants Hospital between January and March 1983. The mean cost of resection and primary anastomosis, without postoperative complications, was pounds 1,364 (n = 4). Indirect costs accounted for 38%, nursing 25%, medical staff 13%, investigations 8% and consumables 16%. The operation itself accounted for 12% of the total. Complications following major abdominal surgery were studied in a further ten patients. The costs of complications not prolonging hospital stay were: wound infection pounds 64-146; chest infection pounds 21-27; urinary infection pounds 3-6. Complications prolonging hospital stay resulted in considerably greater cost: pelvic abscess pounds 1245; myocardial infarction pounds 476; subphrenic abscess pounds 857; colostomy retraction pounds 764; wound dehiscence pounds 599; incisional hernia pounds 1723, and major chest infection pounds 258. Owing to high fixed costs, the main factor in determining cost for bowel resection and complications was length of hospital stay.

Determinants of long-term survival after major surgery and the adverse effect of postoperative complications.
OBJECTIVE: The objective of this study was to identify the determinants of 30-day postoperative mortality and long-term survival after major surgery as exemplified by 8 common operations. SUMMARY BACKGROUND DATA: The National Surgical Quality Improvement Program (NSQIP) database contains pre-, intra-, and 30-day postoperative data, prospectively collected in a standardized fashion by a dedicated nurse reviewer, on major surgery in the Veterans Administration (VA). The Beneficiary Identification and Records Locator Subsystem (BIRLS) is a VA file that depicts the vital status of U.S. veterans with 87% to 95% accuracy. METHODS: NSQIP data were merged with BIRLS to determine the vital status of 105,951 patients who underwent 8 types of operations performed between 1991 and 1999, providing an average follow up of 8 years. Logistic and Cox regression analyses were performed to identify the predictors of 30-day mortality and long-term survival, respectively. RESULTS: The most important determinant of decreased postoperative survival was the occurrence, within 30 days postoperatively, of any one of 22 types of complications collected in the NSQIP. Independent of preoperative patient risk, the occurrence of a 30-day complication in the total patient group reduced median patient survival by 69%. The adverse effect of a complication on patient survival was also influenced by the operation type and was sustained even when patients who did not survive for 30 days were excluded from the analyses. CONCLUSIONS: The occurrence of a 30-day postoperative complication is more important than preoperative patient risk and intraoperative factors in determining the survival after major surgery in the VA. Quality and process improvement in surgery should be directed toward the prevention of postoperative complications.

Postoperative complications in patients receiving suramin therapy.
BACKGROUND: Suramin is an antiparasitic agent that is currently being evaluated for antineoplastic activity. Documented toxicities of suramin include adrenal and renal insufficiency, coagulation factor abnormalities, immunosuppression, and polyneuropathy. These adverse effects have potential for contributing to postoperative morbidity in surgical patients. Because no experience with suramin has been reported in the surgical literature, this 5-year retrospective review of postoperative complications in patients receiving suramin was performed. METHODS: From a review of 171 charts, 14 patients were identified who had undergone a major surgical procedure either while receiving intravenous suramin or within 1 year after its administration. Primary diagnoses included prostate cancer (six), lymphoma (four), ovarian cancer (two), colon cancer (one), and glioblastoma (one). All patients received replacement dose hydrocortisone at the initiation of suramin therapy and thereafter. RESULTS: Eighteen major surgical procedures were performed with 18 complications occurring in five patients. The predominant complications encountered were hemorrhage (five), impaired wound healing (three), and bowel dysmotility (two). A highly significant relationship existed between the incidence of complications and interval from completion of suramin therapy to the time of operation (p < 0.0005), with 17 of the 18 morbidities occurring within the first month. The length of operation (p < 0.05) and amount of blood transfused during the procedure were related to postoperative morbidity (p < 0.05). No other factors evaluated were correlated to complications. CONCLUSIONS: This experience suggests the avoidance of elective procedures during the first month after suramin therapy and a heightened awareness of the potential for bleeding and wound healing problems in patients receiving suramin who do require an emergent procedure.

A Cochrane Systematic Review finds no significant difference in outcome or risk of postoperative complications between day care and in-patient cataract surgery.
This review was conducted to determine reliable evidence regarding the safety, feasibility, effectiveness, and cost-effectiveness of cataract extraction performed as a day care versus in-patient procedure. The search to identify randomized controlled trials comparing day care and in-patient surgery for age-related cataract included the Cochrane Eyes and Vision Group Trials Register, the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE and LILACS Latin American and Caribbean Literature on Health Sciences. Assessment of methodological quality was based on criteria defined by the Cochrane Collaboration. The primary outcome was the achievement of a satisfactory visual acuity 6 weeks after operation. Two trials, involving a total of 1284 people, are included. One trial reported statistically significant differences in early postoperative complication rates in the day care group, which had no clinical relevance to visual outcomes 4 months postoperatively. Mean change in visual acuity Snellen lines of the operated eye 4 months postoperatively was 4.1 standard deviation SD 2.3 for the day care group and 4.1 SD 2.2 for the in-patient group. Costs were 20% more for the in-patient group attributable to higher costs for overnight stay.

Correlation of preoperative urodynamic findings to postoperative complications following pancreas transplantation.
Urological complications are common following pancreas transplantation with bladder drainage. Some investigators have excluded patients from pancreas transplantation because of abnormal preoperative urodynamics. To determine the risk of an abnormal bladder in bladder-drained pancreas transplantation, we prospectively evaluated 23 type I diabetic patients undergoing pancreas transplantation with preoperative urodynamics. For study purposes, criteria for an abnormal urodynamic evaluation were a bladder capacity of greater than 1,000 cc, absence of normal detrusor contractility and an abnormal voiding pattern. In addition, an abnormal study was defined by the presence of 2 or more of the following: 1) suppressed proprioception at 250 cc or at a volume of greater than 50% of bladder capacity, 2) peak flow of less than 10 cc per second, 3) interval to peak flow of greater than 30 seconds or 4) post-void residual of greater than 150 cc. Of the 23 patients 10 (43%) had abnormal preoperative urodynamic studies. All 23 patients underwent pancreas transplantation with bladder drainage, alone or in combination with a kidney transplant. The incidence of urological complications was 3.1 and 3.4 per patient, respectively, in the normal and abnormal groups (p = 0.126). Patient and graft survival rates were similar between the 2 groups (p > 0.5). We were unable to show that abnormal preoperative urodynamic studies preclude successful pancreas transplantation with bladder drainage or predict an increase in postoperative complications.

The incidence of posterior capsule disruption during phacoemulsification and associated postoperative complication rates in dogs: 244 eyes (1995-2002).
OBJECTIVE: The objective of this retrospective study was to report the incidence of posterior capsule disruption during routine phacoemulsification and to document the postoperative outcomes and complications in eyes with posterior capsule disruption compared with eyes with intact posterior capsules. PROCEDURES: Records of 143 dogs (244 eyes) were reviewed. Data collected included whether the posterior capsule was disrupted, whether the disruption was planned or accidental, whether an intraocular lens was implanted, and visual outcome. Records were reviewed for postoperative complications. Intraocular lens implantation rates, complication rates, and visual outcomes were compared between intact and disrupted posterior capsule groups using Chi-square analyses. RESULTS: The posterior capsule was disrupted in 33/244 eyes (14%). Planned capsulotomies accounted for 36% of the disruptions. Intraocular lenses were implanted in 76% of eyes without a disruption of the posterior capsule and in 31% of eyes with a posterior capsule disruption. Intraocular lenses were more likely to be implanted in eyes with a planned disruption of the posterior capsule (7/12; 58%) than in eyes with an accidental disruption (3/20; 15%). There were no significant differences in postoperative complications or visual outcome between eyes with posterior capsule disruption and those without. CONCLUSIONS: The most significant complication of posterior capsule disruption during phacoemulsification is the inability to implant an intraocular lens. Intraocular lenses are more likely to be placed in eyes with intentional disruptions of the posterior capsule than those with accidental ruptures.

The lithotomy position in colon surgery. Postoperative complications.
The modified lithotomy position frequently is used in general surgery because it gives excellent simultaneous access to the abdomen and perineum. There are a variety of complications that may occur including lumbosacral plexus stretch, sciatic and peroneal nerve injury, and compartment syndrome of the legs. Through preoperative nursing assessment of a patient's age, nutritional status, skin condition, pre-existing disease state, and anticipated type and length of surgical procedure, patients at risk for developing postoperative complications may be identified. The perioperative nurse's role is to use this knowledge to assist the surgical team in safe patient positioning and optimal intraoperative care.

Combined anterior craniofacial resection for tumors involving the cribriform plate: early postoperative complications and technical considerations.
OBJECTIVE: Combined craniofacial resection has become the standard approach for malignant tumors involving the cribriform plate and anterior cranial fossa. Despite its widespread application, however, many surgeons agree that the procedure carries a risk of significant morbidity and even mortality. The purpose of this study was to analyze the experience at a single institution to determine the incidence of early postoperative complications encountered after combined craniofacial resection of tumors involving the cribriform plate and to provide information to improve management. METHODS: Between 1987 and 1997, 168 patients underwent combined craniofacial resection at the National Cancer Institute of Milan for tumors involving the cribriform plate. Patient charts, operative notes, follow-up clinic notes, radiographic studies, and pathology reports were analyzed. Morbidity encountered in the first 30 cases was compared with that encountered in the subsequent 138 cases. RESULTS: The most frequently encountered pathological findings were adenocarcinoma (53.6%), squamous cell carcinoma (17%), and esthesioneuroblastoma (9.8%). Eight patients (4.7%) died, 6 of whom were among the first 30 patients to undergo resection. Among patients with fatal complications were three with meningoencephalitis, three with intracranial hemorrhage, and one with myocardial infarction. Fifty patients (29.7%) had nonfatal morbidity; 16 of these patients were among the first 30 patients operated. Transient cerebrospinal fluid leakage was the most frequent adverse effect (9.5%); 12 patients (7.1%) had pneumocephalus, 3 (1.8%) had meningitis, 4 (2.4%) had wound infections, 3 (1.8%) experienced transient impairment of mental status, 3 (1.8%) had transient diplopia, 2 (1.2%) had diabetes insipidus, and 1 (0.6%) had bone flap necrosis. CONCLUSION: We observed a dramatic decrease in mortality and morbidity in patients who underwent combined craniofacial resection after the first 30 cases in our series. Improvement of specific aspects of surgical technique, such as more refined reconstructive methods and improved prophylactic antibiotic therapy, is at least partly responsible for this favorable trend.

[Evaluation of risk factors in the development of postoperative complications in patients undergoing liver resection for cancer].
A consecutive series of 134 hepatic resections for primary and metastatic cancer were analyzed to identify the risk factors for post-operative complications in patients with and without impaired liver reserve. Between January 1992 and January 2000 were performed 55 hepatectomies (41%--group 1) in 54 cirrhotic patients for hepatocarcinoma and 79 hepatic resections (59%--group 2) in 66 patients for primary hepatic malignancies or metastatic liver tumours in non cirrhotic liver. Among major postoperative complications bile leakage was recorded in 8 patients (6%) (6% with impaired liver reserve and 6% with normal reserve), hepatic failure in 8 patients (6%) (9% vs 4%; P = NS), ascites in 7 patients (5%) (11% vs 1%; P = 0.01), pneumonia in 4 patients (3%) (5% vs 1%; P = NS), intra-abdominal abscess in 2 patients (1%) (2% vs 1%; P = NS), postoperative haemorrhage in 2 patients (1%) (4% vs 0; P = NS), and gastrointestinal bleeding in 2 patients (1%) (4% vs 0; P = NS). There were 6 perioperative deaths (4%) (7% vs 2%; P = NS). The mean hospital stay was 21 +/- 10 days (range: 5-57) (24 +/- 10 vs 20 +/- 10; P = 0.02). Liver resection is a safe procedure even in cirrhotic patients providing they are well selected and there is minimal intraoperative blood loss.
