Primary esophageal repair for Boerhaave's syndrome.

BACKGROUND: Boerhaave's syndrome is the most sinister cause of esophageal perforation. The mediastinal contamination with microorganisms, gastric acid, and digestive enzymes results in a mediastinitis that is often fatal if untreated. METHODS: We present a series of 21 patients seen in our unit in the 10 years 1987 to 1996. Esophageal repair was performed in 17 (81%) of them. After the resuscitation of the patient in the intensive care unit, our strategy is primary esophageal repair with a single layer of interrupted absorbable sutures combined with mediastinal toilet, mediastinal drainage, and drainage gastrostomy. The majority of patients (12/21) were referred more than 24 hours after perforation. RESULTS: The mean age of the patients was 60+/-17 years. The mean stay in the intensive care unit was 1.6+/-1.8 days and the median hospital stay, 14 days. There were three deaths, an overall mortality rate of 14.3%. CONCLUSIONS: When combined with mediastinal toilet, mediastinal drainage, and drainage gastrostomy, primary esophageal repair for Boerhaave's syndrome gives an acceptable mortality and should not be reserved for patients seen within 24 hours after spontaneous rupture.

Iatrogenic oesophageal perforations: a clinical review.

Thirty patients with iatrogenically induced perforation of the oesophagus were managed in our unit between January 1986 and December 1996. Thirteen (43%) of these injuries were referred after upper gastrointestinal endoscopy performed by physicians. Ten (33%) cases were referred by ENT surgeons and general surgeons referred 7 (23%) cases. Of these patients, 15 (50%) had no abnormality of the oesophagus found before perforation. Only 18 (60%) of patients were referred within 24 h of injury. The mean duration of care required in the intensive care unit was 1.5 days +/- 2.5 days and the mean inpatient hospital stay 26.5 days +/- 22.1 days. The mortality was 10% (three cases). Oesophageal perforation remains a serious life-threatening injury. The early diagnosis of this uncommon condition requires a high index of suspicion as the symptoms are often non-specific. Identification of the site of perforation is necessary as the management of cervical and thoracic perforations differs considerably. Early referral combined with appropriate therapy would appear to result in a better outcome than previously published data. It is therefore suggested that patients with this relatively rare condition should be referred as soon as possible to a centre with expertise in its management.

Thoracoscopic debridement of empyema thoracis.

BACKGROUND: The primary treatment of empyema thoracis remains intercostal tube drainage together with antibiotics. Failure of primary treatment has until recently been an indication for thoracotomy and decortication. Video-assisted thoracoscopic debridement (VATD) has increased the available treatment options but requires validation. METHODS: A retrospective analysis was undertaken of 44 consecutive patients who presented for surgical treatment of empyema thoracis over a 3-year period. RESULTS: Two patients were unsuitable for VATD and were treated with open decortication (OD). Thirty patients were successfully treated by VATD. Two patients were converted to OD at the first operation, and 10 patients required OD as a second procedure. The mean duration of preoperative symptoms before referral was 37.6 +/- 11.8 days (VATD) and 40.1 +/- 11.6 days (OD) (p = not significant). The mean duration of hospitalization before transfer was 13.7 +/- 2.4 days (VATD) and 11.5 +/- 3.4 days (OD) (p = not significant). Intercostal drainage was required for 4.0 +/- 0.3 days (VATD) and 8.5 +/- 2.0 days (OD) (p = 0.004). The postoperative hospital stay was 5.3 +/- 0.4 days (VATD) and 10.3 +/- 2.1 days (OD) (p = 0.001). CONCLUSIONS: Primary surgical therapy with VATD should be considered for all patients with pleural empyema, irrespective of the duration of symptoms. This approach does not preclude OD as a secondary procedure or conversion to OD after initial thoracoscopic assessment. The major advantages of VATD over OD are a shorter duration of postoperative intercostal drainage and reduced postoperative hospitalization.

Trace nutrients. 4. Iodine in British food.

1. The amounts of iodine in nationally representative samples of prepared and cooked groups of foods and in a wide variety of individual foods and food products were determined colorimetrically. The amounts of erythrosine, a red food colour containing 577 mg I/g were also determined in selected foods and diets by high-performance liquid chromatography. 2. The average British diet was calculated to provide 323 micrograms I/d but only 255 micrograms if two fruit samples containing large amounts of glacé cherries were discounted. Of the total, 92 micrograms was derived from liquid milk. Meat and meat products provided 36 micrograms and cereal products 31 micrograms, but fresh fruits and sugars, vegetables and beverages provided little I. Fish and fish products, though rich in I, contributed only 5% to the total intake. 3. Milk was the most variable as well as the most important individual source of I. Summer milk samples contained 70 micrograms/kg and winter milk 370 micrograms/kg on average. Milk products, including butter and cheese, and eggs were also rich in I. 4. Some processed foods contained erythrosine, particularly glacé cherries and some pink or red confectionery items, biscuits, cherry cake, canned strawberries and luncheon meat. However, none of these are major foods in the average household diet and erythrosine would therefore contribute little more than 10 micrograms I/d to most diets. 5. The average daily intake of I was lower than in similar similar studies in the USA, but was twice the provisional UK recommended intake. This study provides no evidence that I intakes in the UK could be too low or too high for health.U
