[Advances in the treatment of postoperative complications after abdominal operations. A comparative, retrospective analysis of two reported periods (author's transl)].

Period I (1958-64)included 227 complications, period II 257 complications. Altogether, 484 complications were evaluated in 436 cases. The by far higher lethality in period I (71,3 percent) compared to 41,1 per cent in period II can be explained by the lower frequency of relaparotomy of 24,6 percent (52,3 per cent in period II). The mortality after relaparotomy was almost equal in both periods. The central problem in the therapy of postoperative surgical complications can consequently be seen in the indications for relaparotomy. Therefore, to improve the results, a more active diagnosis and indication and adequate performance of the operation are necessary.

Late postoperative complication of the foldable lens implantation: opacification of the intraocular lenses.

OBJECTIVE: To analyze the cause of the late postoperative opacification of the lens optic of implanted intraocular lens (IOL). METHODS: Twenty-two foldable hydrophilic acrylic lenses with opacification of their optics in 19 patients were taken out of the eye by surgery and examined by gross examination and microscopy. The lenses were stained with alizarin red and von Kossa method (special stains for calcium). Some were submitted for energy dispersive X-ray spectroscopy and scanning electron microscopy. The same kind of transparent IOLs were examined as the control group. RESULTS: Granular deposits of variable sizes were revealed on the surface and within the lens optics. The deposits that were stained positive with alizarin red and von Kossa method showed the presence of calcium. Energy dispersive X-ray spectroscopy demonstrated the calcium and the phosphate present in the deposits. The distribution of the granules was dense in the central part of the optic and sparse at its periphery. There were negative findings in the haptics of the lenses taken out and the control lenses. CONCLUSION: The cause of the opacification of the foldable lens optics is the deposits that consist of calcium and phosphate occurring inside and on the surface of the optics.

[Postoperative complications after Caldwell-Luc radical surgery and possibilities of surgical therapy].

The causes for and the avoidance of postoperative complaints following operations on the maxillary sinus were discussed. Additional surgery following the Caldwell-Luc operation is meaningful only in connection with the secondary coverage of defects of the facial wall of the maxillary sinus. Dura is used for coverage. Mucosa from the palate, which is positioned with a new balloon tamponade, is used for larger defects.

Postoperative complication rate of thoracotomy in patients with normal and abnormal pulmonary function.

Recent advances in perioperative monitoring, anesthesia, and postoperative care have resulted in a more generous attitude towards performing thoracic surgery in patients with reduced pulmonary function. In our hospital 100 patients admitted for thoracotomy with or without pulmonary resection were classified on the basis of their pulmonary function: group I (n = 33) normal, group II (n = 40) moderate reduction, group III (n = 27) marked reduction. The mean and standard deviation in groups I, II, and III were: FEV 1 in % VC: 78 +/- 6, 72 +/- 7, and 58 +/- 10; RV in % TLC: 24 +/- 7, 35 +/- 8, and 43 +/- 9; Resistance, kPal/1/sec: 0.2 versus 0.3 versus 0.5. After surgery there were three postoperative deaths from cardiovascular complications without respiratory failure; all 3 patients were in group II and younger than 70 years. Only one patient (classified as group III and 59 years old) died from a respiratory complication (respiratory insufficiency) after a palliative operation on a large adenocarcinoma. Our data demonstrate that markedly reduced preoperative lung function is not necessarily associated with high risk in thoracic surgery--even in elderly persons--provided intensive pre- and postoperative care is guaranteed.

Tuboovarian abscess: a postoperative complication of endometrial ablation.

BACKGROUND: Global endometrial ablation may be associated with serious complications. CASE: We present a case of bilateral tuboovarian abscesses that developed 50 days postoperatively after a thermal ablation. The patient underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy. CONCLUSION: Infectious morbidity is known to occur after thermal endometrial ablation. Further investigation is required into ways of reducing the risks of endometrial ablation.

Caecal volvulus in a child: an unusual postoperative complication.

A 2.5 year old dysmorphic child with severe gastro-oesophageal reflux was admitted for elective fundoplication. Three days postoperatively, she developed progressive signs of intestinal obstruction. The diagnosis of caecal volvulus was suggested on the plain radiographic appearance, confirmed at laparotomy and treated by right hemicolectomy. The predisposing factors, diagnosis and approach to surgical management are discussed.

Does perioperative immunonutrition reduce postoperative complications in patients with gastrointestinal cancer undergoing operations?

Perioperative immune modulation using specialized enteral diets containing specific immunonutrients may improve postoperative outcomes in critically ill patients compared with standard formulas. A study from Italy involving 305 patents with histologically confirmed cancer of the gastrointestinal tract undergoing major elective surgery and preoperative weight loss < 10% demonstrated that a specialized preoperative oral formula enriched with arginine, omega-3 fatty acids, and RNA for 5 days before surgery with no nutritional support postoperatively (preoperative group) was as effective as pre- and postoperative administration of the same enriched formula (perioperative group) in decreasing the incidence of postoperative infections and length of hospital stay. Both pre- and perioperative immunonutritional strategies were superior to the conventional approach (no artificial nutrition perioperatively).

[Partial liver resections: mortality, morbidity and risk factors for postoperative complications in 133 patients/137 operations; Utrecht University Medical Center 1991/2000].

OBJECTIVE: Evaluation of the results of partial liver resections for both benign and malignant abnormalities and the identification of risk factors for the development of complications. DESIGN: Descriptive, retrospective. METHOD: All consecutive partial liver resections performed between January 1991 and October 2000 at the University Medical Centre Utrecht, the Netherlands, were reviewed for preoperative, peroperative and postoperative parameters. Risk factors were determined by means of a univariate analysis and a multiple logistic regression analysis. The 5-year survival rates were calculated using the Kaplan-Meier method. RESULTS: A total of 133 patients (71 men and 62 women; median age: 58 years (range: 17-79)) underwent 137 hepatic resections for benign (n = 29) and malignant (n = 108) liver abnormalities. In total, 74 procedures (54%) were considered to be major hepatic resections and blood transfusion was required in 97 patients (71%). A total of 43 complications was observed in 32 patients (32/137; 23%). Eight patients died as a result of postoperative complications (8/137; 5.8%). Independent risk factors associated with the development of major complications were a major resection (OR: 3.6) and more than 2 peroperative units of packed cells (OR: 5.0). The principal indication for liver resection were colorectal metastases (n = 69). The 5-year survival rate after liver resection for colorectal metastases was 38% (95% CI: range 21-54) with a 5-year disease-free survival rate of 25% (range 10-41). The postoperative mortality in this group was 2.9%. CONCLUSION: After partial liver resection for benign and malignant lesions the mortality was 5.8% and the morbidity 23%. The risk of postoperative morbidity was related to the number of peroperative units of packed cells and the extent of the resection.

Hydrothorax after ventriculoperitoneal shunt placement in a premature infant: an iatrogenic postoperative complication. Case report.

The authors describe the case of a prematurely born infant who developed hydrothorax after ventriculoperitoneal (VP) shunt placement for treatment of posthemorrhagic communicating hydrocephalus. Prior to shunt placement a bout of necrotizing enterocolitis created intense abdominal and peritoneal scarring. The authors postulate that the scarring created poor peritoneal absorption capacity of cerebrospinal fluid (CSF), with preferential flow of CSF from the peritoneal to the pleural cavity. A (99m)Tc-diethylenetriamine pentaacetic acid radionucleotide study enabled the authors to rule out shunt malfunction, and preferential transdiaphragmatic flow of CSF from the abdomen to the thoracic cavity was demonstrated. The hydrothorax resolved after conversion of the VP shunt to a ventriculoatrial shunt. Respiratory distress after VP shunt placement should be considered an unusual but important sentinel symptom in the differential diagnosis of postoperative shunt complications.

Effects of antibiotic prophylaxis on postoperative complications after rumenotomy in cattle.

A single preoperative dose of antibiotic proved as effective as a preoperative and 7-day postoperative course in reducing complications following rumenotomy in cattle. Exploratory rumenotomy was performed on 29 healthy Angus steers, which were allotted to the following treatment groups: (1) no antibiotic therapy, (2) single-dose, preoperative, antibiotic prophylaxis, using potassium penicillin G, and (3) preoperative potassium penicillin G prophylaxis, followed by a 7-day postoperative course of procaine penicillin G. Steers receiving antibiotics had significantly greater postoperative feed intake, lower rectal temperatures, and fewer abscesses at the surgical site than those receiving no antibiotics. There was no significant difference between animals receiving a single preoperative dose of antibiotic and those treated for an additional 7 days after surgery. In human medicine, it is generally agreed that a single preoperative dose of antibiotic offers effective prophylaxis. There are few published reports on antimicrobial prophylaxis in the veterinary literature, particularly in regard to large animals. Considering USDA requirements for milk withholding times and withdrawal times prior to slaughter for food animals receiving antibiotics, the findings of this study have medical as well as economic value.
