[Gluteal abscess complicated by sepsis as the expression of Crohn's disease].

Two young women, aged 19 and 25 years, suffered from persistent perianal sepsis after local drainage of unusual gluteal abscesses. Preoperative CT scanning showed unrecognised and inadequately treated abscesses and signs of inflammatory bowel disease. Both patients underwent a reoperation: affected bowel segments were removed, stomas were created and abscesses were drained. In the case of unusual perianal abscesses the diagnosis 'Crohn's disease' must be considered. Preoperative examinations should include CT or MRI scans of the abdomen and pelvis. Intraoperative colonoscopy can often be helpful in assessing the extent of the affected bowel segment.

[Acute pancreatitis--a protocol for diagnosis and treatment].

Acute pancreatitis remains a disease with high morbidity and mortality. Acute pancreatitis can be subdivided in acute interstitial pancreatitis and necrotising pancreatitis, largely compatible with clinically mild and severe pancreatitis. This diagnosis is made on the basis of patient history, physical examination, laboratory parameters, contrast CT scan and, occasionally, endoscopic retrograde cholangiopancreatography. Prognosis on admission can be established using a scoring system such as the modified Glasgow score, the Ranson score and the 'Acute physiology and chronic health evaluation'--(APACHE)-II-score. The treatment of acute pancreatitis is primarily conservative. Indications for surgical intervention are: progressive sepsis despite maximum conservative management, an established infection of (peri)pancreatic necrosis, peripancreatic abscess and perforation of stomach, small intestine or colon. The purpose of an operation is to remove necrotic tissue, achieve adequate drainage of the necrotic area or to treat a perforation. The Groningen and Utrecht University Hospitals have collaborated to develop a protocol to standardise the diagnostic approach, management, timing and choice of surgical intervention, as well as to prospectively investigate the effect of such a strategy in patients with acute pancreatitis.

[Reduced risk of complications associated with severe acute (necrotizing) pancreatitis by administration of antibiotics; results from a literature review].

OBJECTIVE: To determine the role of antibiotics in patients with acute pancreatitis. DESIGN: Literature review. METHOD: A Medline search for randomised clinical trials (RCTs) during the period 1990-1999 was carried out using the key words 'pancreatitis', 'acute' and 'antibiotics'. Outcome measures were pancreas-related infection, sepsis and death. RESULTS: Four RCTs were identified. Control groups were not given antibiotics. Based on the pooled data, the differences in risk in favour of the groups treated with various antibiotics were as follows: -14% (95% CI: -26(-)-1; p = 0.04) for pancreas infections, -25% (95% CI: -39(-)-12; p = 0.0002) for sepsis and -13% (95%-BI: -22(-)-3; p = 0.007) for death. CONCLUSION: Administration of antibiotics to patients with severe acute (necrotising) pancreatitis reduces the risk of serious complications.

Quality of life after severe bacterial peritonitis and infected necrotizing pancreatitis treated with open management of the abdomen and planned re-operations.

OBJECTIVE: To determine quality of life after severe bacterial peritonitis and infected necrotizing pancreatitis treated with open management of the abdomen and planned re-operations. DESIGN: Retrospective chart review. SETTING: University hospital intensive care unit, general wards, and outpatient department. PATIENTS: Forty-one patients who survived severe bacterial peritonitis and infected necrotizing pancreatitis treated with open management of the abdomen and planned re-operations. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Over a period of 7 yrs, 95 patients underwent open management of the abdomen and planned re-operations for severe bacterial peritonitis and infected necrotizing pancreatitis. Thirty-nine patients died during the initial intensive care unit stay and 12 as a result of nonperitonitis-related systemic diseases after discharge. Four patients were lost or excluded from final analysis. Long-term morbidity and quality of life using Karnofsky and Rankin scores at discharge and at follow-up at least 1 yr after discharge (mean: 4 yrs) and the Sickness Impact Profile (SIP) were determined. The remaining 41 patients reviewed showed significant long-term morbidity, including dysfunction of the abdominal wall resulting from herniation, persistent polyneuropathy, and mental disorders needing psychiatric support. Patients having persistent polyneuropathy and, to a lesser extent, mental disorders, showed significantly lower Karnofsky, higher Rankin, and higher SIP scores. After discharge, performance status of patients improved significantly, as shown by higher Karnofsky and lower Rankin scores, and, because Karnofsky and Rankin scores are closely related to SIP scores, higher SIP scores. Especially in measuring quality of life in terms of social and role management, assessment of the SIP proved to have additional value. CONCLUSIONS: About three-quarters of patients who survive open management of the abdomen and planned re-operations for severe bacterial peritonitis and infected necrotizing pancreatitis regain a good quality of life. Some patients, especially those who suffer from persistent polyneuropathy and mental disorders, show restrictions in daily life.

A standardised and reproducible model of intraabdominal infection and abscess formation in rats.

OBJECTIVE: To develop a standardised and reproducible model of intra-abdominal infection and abscess formation in rats. DESIGN: Experimental study. SETTING: University hospital, The Netherlands. SUBJECTS: 36 adult male Wistar rats. INTERVENTIONS: In 32 rats, peritonitis was produced using two different concentrations of Escherichia coli (E. coli) and Bacteroides fragilis (B. fragilis) incorporated in fibrin clots (E. coii 1 x 10(5) colony forming units (CFU)/ml or 1 x 10(8) CFU/ml, B. fragilis: 1 x 10(8) CFU/ml). Four rats with fibrin clots without bacteria served as uninfected controls. MAIN OUTCOME MEASUREMENTS: Macroscopy and bacterial counts in peritoneal fluid, blood, and fibrin clots after 24 hours, 4 days, 7 days, and 4 weeks. RESULTS: Macroscopically, there were signs of intra-abdominal infection and abscesses. With the higher starting concentration of E. coli, macroscopic signs were more pronounced and in nearly all rats bacterial counts in peritoneal fluid and fibrin clots showed persistently high numbers of E. coli and B. fragilis for at least 7 days (E. coli = 2 x 10(3) to 1 x 10(6) CFU/ml and 5 x 10(7) to 9 x 10(8) CFU/clot; B. fragilis = 1 x 10(3) to 1 x 10(6) CFU/ml and 5 x 10(7) to 6 x 10(8) CFU/clot). CONCLUSION: This standardised and reproducible model of intra-abdominal infection and abscess formation seems well suited for further use and development in experiments on the pathophysiology of intra-abdominal infection and abscesses.

Twelfth rib resection: a direct posterior surgical approach for subphrenic abscesses.

OBJECTIVE: To assess the results of twelfth rib resection as a direct posterior surgical approach to subphrenic abscesses in case of failure of percutaneous drainage, abandonment of percutaneous drainage in view of a too high risk of perforation of adjacent organs, or contamination of the pleural space, or an inaccessible abdomen. DESIGN: Retrospective study. SETTING: University hospital, The Netherlands. PATIENTS: 17 patients who required rib resection for subphrenic abscesses that developed after infected necrotising pancreatitis, splenectomy, or anastomotic disruption. INTERVENTIONS: 18 rib resections. MAIN OUTCOME MEASURES: Outcome and morbidity. RESULTS: Twelfth rib resection was successfully in 13 of 17 patients. Four patients died from multiple organ failure despite subsequent (re) laparotomies for additional surgical drainage. CONCLUSION: Twelfth rib resection can be useful for the treatment of subphrenic abscesses in selected patients.

Open management of the abdomen and planned reoperations in severe bacterial peritonitis.

OBJECTIVE: To assess the results of open management of the abdomen and planned re-operations in severe bacterial peritonitis after perforation or anastomotic disruption of the digestive tract. DESIGN: Retrospective study. SETTING: University Hospital, The Netherlands. SUBJECTS: 67 consecutive patients. INTERVENTIONS: Open management of the abdomen and planned reoperations. MAIN OUTCOME MEASURES: Hospital morbidity and mortality, long-term follow-up. RESULTS: 38 patients developed multiple organ failure (MOF), but 29 needed only ventilatory and inotropic support. The mean number of re-operations was nine. 16 patients developed severe bleeding and 16 fistulas. In-hospital mortality was 42% (n = 28). Long-term morbidity, particularly the number of abdominal wall defects (n = 10), was considerable. CONCLUSION: Despite open management of the abdomen and planned re-operations, mortality of severe bacterial peritonitis still continues to be too high, and both short and long-term morbidity are appreciable. The value of open management of the abdomen and planned re-operations rests only on the clinical observation that other conventional surgical treatments of severe bacterial peritonitis often fail.

Surgical management of severe secondary peritonitis.

BACKGROUND: Despite advances in diagnosis, surgery, antimicrobial therapy and intensive care support, the mortality rate associated with severe secondary peritonitis remains unacceptably high. This article presents various surgical treatment strategies for severe secondary peritonitis, emphasizing the role of open management of the abdomen and planned relaparotomies. METHODS: Material was identified from previous review articles, references cited in original papers and a Medline search of the literature. RESULTS AND CONCLUSION: Surgical treatment of severe secondary peritonitis is highly demanding and very complex. The combination of improved surgical techniques, antimicrobial therapy and intensive care support has improved the outcome of such peritonitis following perforation or anastomotic disruption of the digestive tract, or infected necrotizing pancreatitis. However, aggressive surgical treatment strategies, such as open management of the abdomen and planned relaparotomies, may have reached their limits.

[Bilateral dislocation fracture of the head of the humerus. Arthroplasty and/or arthrodesis].

Functional recovery after bilateral comminuted fractures of the humeral head with posterior dislocation is poor. When reposition and internal fixation fail, the remaining alternatives are (hemi)arthroplasty and/or arthrodesis. In a 50-year-old patient, we treated the dominant shoulder by arthrodesis; a Neer prosthesis was inserted at the other side. Using this strategy, the advantages of both techniques were combined with an acceptable functional recovery, which ist especially important for young and active patients.

Fulminant acute pancreatitis and infected necrosis: results of open management of the abdomen and "planned" reoperations.

BACKGROUND: Controversy still surrounds the management of fulminant acute necrotizing pancreatitis. Because mortality rates continue to be high, especially in patients with fulminant acute pancreatitis and infected necrosis, aggressive surgical techniques, such as open management of the abdomen and "planned" reoperations, seem to be justified. STUDY DESIGN: From 1988 through 1995, 28 patients with fulminant acute pancreatitis and infected necrosis were treated with open management of the abdomen followed by planned reoperations at our surgical intensive care unit. RESULTS: All patients had infected necrosis with severe clinical deterioration: 12 patients had an Acute Physiology and Chronic Health Evaluation (APACHE) II score > or = 20 and 16 patients had a Simplified Acute Physiology Score (SAPS) > or = 15. Nineteen patients suffered from severe multiorgan failure; the remaining 9 patients needed only ventilatory and inotropic support. The mean number of reoperations was 17. In 14 patients, major bleeding occurred; fistula developed in 7. Later, 9 abscesses were drained percutaneously. The hospital mortality rate was 39%. Longterm morbidity in survivors was substantial, especially concerning abdominal-wall defects. CONCLUSIONS: Open management of the abdomen followed by planned reoperations is an aggressive but reasonably successful surgical treatment strategy for patients with fulminant acute pancreatitis and infected necrosis. Morbidity and mortality rates were high, but in these critically ill patients, such high rates could be expected. Because management and clinical surveillance require specific expertise, management of these patients is best undertaken in specialized centers.

Novel approach to the treatment of intestinal fistula in the inaccessible abdomen: transbursal end-to-side duodenogastrostomy.

BACKGROUND: Treatment of enterocutaneous fistula in patients with intra-abdominal sepsis and a surgically inaccessible abdomen is frequently unsuccessful. METHODS: A new approach has been devised: total disconnection of the proximal digestive tract, which can be performed through the bursa omentalis without entering the scarred abdomen. RESULTS: The procedure was carried out in four patients with high-output small bowel fistula and an inaccessible abdomen. Output of fistulas stopped promptly, recovery from intra-abdominal sepsis was achieved, the abdomens became accessible again and continuity of the digestive tract could be restored in all patients after intervals of 2-5.5 months. CONCLUSION: Transbursal end-to-side duodenogastrostomy is a useful procedure when traditional surgical interventions have failed or cannot be applied.

Predictors of recurrence of fulminant bacterial peritonitis after discontinuation of antibiotics in open management of the abdomen.

OBJECTIVE: To assess a scoring system for predicting recurrence of fulminant bacterial peritonitis after discontinuation of antimicrobial treatment in patients being treated by open management of the abdomen for persistent bacterial peritonitis after perforation of the digestive tract, anastomotic disruption, or necrotising pancreatitis. DESIGN: Retrospective study. SETTING: University Hospital, The Netherlands. SUBJECTS: 58 consecutive patients. MAIN OUTCOME MEASUREMENTS: Recurrence of fulminant bacterial peritonitis and survival. RESULTS: 13 of the 58 patients (22%) died during the initial course of antimicrobial drugs. 14 of the remaining 45 patients had a recurrence of fulminant bacterial peritonitis after discontinuation of antimicrobial drugs, 4 of whom died. Predictive criteria included raised white cell count (WCC) (p = 0.02), duration of initial antibiotic treatment (p = 0.05), and deterioration in Simplified Acute Physiology Score (p = 0.05). Using the WCC and the duration of initial antimicrobial treatment together with other variables that showed a predictive trend (body temperature, percentage band cells, underlying disease, and use of inotropic agents), in a new scoring system (0-12), fulminant bacterial peritonitis did not recur when the score was 0-3, but in 9 of 11 patients with a score of 6 or more it did (p < 0.001). CONCLUSION: Patients at increased risk of recurrence of fulminant bacterial peritonitis during open management of the abdomen can be identified at the time of discontinuation of antimicrobial treatment by a new scoring system; antimicrobial treatment should not be discontinued in patients with a score of 6 or more.

Gastrointestinal motility and gastric tube feeding in mechanically ventilated patients.

OBJECTIVE: To determine the fasted and fed gastrointestinal motility characteristics that are possibly responsible for gastric retention in mechanically ventilated patients. DESIGN: Prospective, case series. SETTING: Surgical intensive care unit of a university hospital. PATIENTS: Seven patients who required mechanical ventilation for thoracic or combined thoracic-neurologic injuries and nine healthy volunteers. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Antroduodenal manometry was performed during fasting and gastric feeding with a polymeric diet in patients during mechanical ventilation, weaning, and after detubation. Gastric retention volumes were determined during gastric tube feeding. Motility data were compared with recordings from nine healthy volunteers. During the fasting state, under sedation and morphine, the migrating motor complex in patients was significantly (p < .001) shortened: median 32.0 vs. 101.0 mins in healthy volunteers. During gastric tube feeding, the motility pattern did not convert to a normal postprandial pattern until morphine was discontinued. An interdigestive or mixed interdigestive-postprandial pattern was seen during gastric tube feeding in most patients during morphine administration. Most (94%) of the activity fronts during gastric feeding started in the duodenum. Gastric retention percentages during gastric tube feeding were negatively correlated (r2=.44; p < .01) with antral motor activity. CONCLUSIONS: These data suggest that morphine administration affects antroduodenal motility in mechanically ventilated patients. The gastrointestinal motor pattern involved in impaired gastric emptying in morphine-treated patients is characterized by antral hypomotility and persisting duodenal activity fronts during continuous intragastric feeding. The observed motility patterns suggest that early administration of enteral feeding might be more effective into the duodenum or jejunum than into the stomach of mechanically ventilated patients.

Prognostic scoring systems to predict outcome in peritonitis and intra-abdominal sepsis.

BACKGROUND: Early classification of patients presenting with peritonitis and intra-abdominal sepsis by means of objective scoring systems is desirable to select patients for 'aggressive' surgery and to compare results of different treatment regimens. However, none of the existing scoring systems has fulfilled all expectations. METHODS: Evaluation of the value of various scoring systems (Acute Physiology And Chronic Health Evaluation (APACHE) II, Simplified Acute Physiology Score, Sepsis Severity Score, Multiple Organ Failure, Mannheim Peritonitis Index (MPI), Ranson and Imrie) was performed in 50 patients. Additionally, scoring systems were combined to obtain a 'combined score' for the prediction of peritonitis-related in-hospital death. Hazard ratios were calculated in a univariate and multivariate analysis. RESULTS: In the univariate analysis all scoring systems, except Ranson and Imrie, predicted the primary outcome. In the multivariate analysis, only the APACHE II score (hazard ratio 6.7) and the MPI (hazard ratio 9.8) contributed independently to the prediction of outcome. All patients with an APACHE II score of 20 or more and a MPI of 27 or more died in hospital. CONCLUSION: Combination of the APACHE II and the MPI provides the best scoring system fitting clinical goals.

[Surgical treatment of life-threatening mediastinitis following esophageal perforation or leakage after esophagus surgery].

OBJECTIVE: Evaluation of the surgical treatment of life-threatening mediastinitis following oesophageal perforation or leakage after resection for oesophageal cancer. DESIGN: Descriptive retrospective. SETTING: Department of Surgery, University Hospital Utrecht. METHODS: Between June 1989 and October 1994, 18 patients with severe mediastinitis and sepsis following perforation of the oesophagus or leakage after oesophageal resection for oesophageal cancer were treated with aggressive surgery. (Peri-)anastomotic leakage was the cause of mediastinitis and sepsis in 14 patients, 3 patients perforated during endoscopy and 1 patient suffered a spontaneous perforation. Aggressive surgery consisted of removing the oesophageal replacement from the mediastinum, creating an oesophago-cutaneostomy and a feeding enterostomy and drainage of the mediastinum and interpleural spaces. RESULTS: All patients survived; however, postoperative morbidity was high. The alimentary tract was reconstructed in 15 patients. CONCLUSION: Aggressive surgical treatment of life-threatening mediastinitis and sepsis as described here can save severely ill patients. Because of the high postoperative morbidity level only patients with perforations of the oesophagus and early stages of oesophageal cancer should be operated.

Internal fixation of metacarpal and phalangeal fractures with AO minifragment screws and plates: a prospective study.

In a prospective study, 43 patients with 47 metacarpal or phalangeal fractures with significant displacement, rotation, angulation and/or instability were treated with internal fixation using AO minifragment screws and plates. In all fractures an anatomical reduction was achieved. Postoperatively all metacarpal fractures were protected by means of a plaster, in which motion was allowed, whereas all phalangeal fractures were treated by means of a soft bandage. At a review after a mean period of 28 months, 31 patients with 35 fractures out of 34 patients with 38 fractures had regained excellent recovery of total active flexion (92 per cent). Three patients had a poor recovery of total active flexion; one had an infection, the other two were operated on 6 and 14 days after their injury, whereas the mean delay between injury and operation was 3 days. All patients not reviewed had regained good or 100 per cent function.
