Long-term observation and functional state of the esophagus after primary repair of spontaneous esophageal rupture

BACKGROUND

Long-term outcome of patients treated for a spontaneous esophageal rupture (Boerhaave's syndrome) is seldom reported.

METHODS

From 1989 to 2004, 62 esophageal perforations were treated in a single institution. Eighteen patients presented with a spontaneous esophageal rupture. Among them, 15 could be treated with a transthoracic primary repair and constituted the material of the present study. A chart review was performed with special attention to survival, residual symptoms, and anatomic and motility disorders.

RESULTS

Three patients died postoperatively (20%). At last follow-up, 10 patients were alive and 2 had died from unrelated causes. At a median delay of 13 months (3 to 74), 7 patients accepted to undergo complementary investigations. None of them had any anatomic abnormality as checked by barium swallow. Six patients complained of mild symptoms from gastroesophageal reflux. Six patients (85%) presented with esophageal motility disorders on manometry and 4 (54%) had nocturne chronic reflux disease on pH monitoring. Two patients underwent endoscopic ultrasonography, of which one presented with a focal absence of one layer of the esophageal wall within the area of the suture. With time, no patient experienced recurrence, but one developed a cancer in the cervical esophagus.

CONCLUSIONS

These results suggest that esophageal functional disorders are the rule after primary repair of a Boerhaave's syndrome. Whether or not these findings are causal, coincidental, or related to the surgical treatment remains unclear. However, performance of routine postoperative explorations is strongly encouraged for a better understanding of this challenging condition.

Changing patterns and surgical results in adenocarcinoma of the oesophagus

BACKGROUND

Prognosis of oesophageal adenocarcinoma is notoriously dismal. To examine the changing patterns of and treatment strategies for this disease, the longitudinal experience of a single institution over 16 years is reported.

METHODS

The study comprised a retrospective review of 551 consecutive patients operated on for oesophageal cancer between 1979 and 1995, of whom 164 had adenocarcinoma. There were 13 women and 151 men whose mean age was 61 (range 17-82) years.

RESULTS

The prevalence of adenocarcinoma (P = 0.002), that of early tumours (P < or = 0.10), and the resectability rate (P < or = 0.05) increased throughout the period whereas operative mortality rate decreased (P < or = 0.10). Surgical approach changed without influence on long-term survival. Patients referred from endoscopic surveillance programmes for Barrett's oesophagus (n = 16) had an improved survival rate compared with that of non-surveyed patients (P < or = 0.01). Overall 5-year survival after oesophagectomy (17 per cent) improved for the period 1991-1995 when compared with 1979-1982 (P < or = 0.02). Univariate analysis identified tumour node metastasis (TNM) stage, number of diseased lymph nodes, invasion of the oesophageal stump and occurrence of a postoperative complication as significant prognostic variables (P < or = 0.05). Multivariate analysis demonstrated that T stage (P = 0.0002) was the main independent predictor.

CONCLUSIONS

Recent improvement of results reflects patient selection, increased prevalence of early tumours, and dramatic reduction of the risks from oesophagectomy. New therapeutic directions should be investigated for locally advanced tumours.

Esophageal cancer resection in the elderly

OBJECTIVE

Esophageal cancer is a disease whose prognosis is dismal and its surgery involves considerable risks, consequently the opportunity of esophageal resection in elderly patients with esophageal cancer is questionnable. The aim of this study was to analyze, with respect to their age, the outcome of 386 consecutive patients who underwent esophagectomy and simultaneous replacement for cancer.

METHODS

A chart review of all patients with esophageal carcinoma admitted to our institution was undertaken for the period January 1979-December 1994.

RESULTS

The portion of patients of 70 years of age and older (14.5%) has slightly increased during the period. Location to the lower third of the esophagus and adenocarcinoma type were prevalent in the 56 elderly patients (group I), but their postsurgical TNM staging was identical to that of the 330 younger patients (group II). Other clinical features, i.e. preoperative weight loss and the presence of co-morbid diseases, however, were comparable in the two groups. Pulmonary function, as assessed by spirometry, was significantly worse among the older patients, but blood gas determinations were not different. Operative mortality was comparable, between the two groups (10.7% vs 11.2%). Major morbidity included anastomotic leak (10.7% vs 13.6%) and pulmonary complications (17.9% vs 20.6%) in both groups. Excellent palliation of dysphagia was achieved in 92% of the 50 group I patients who survived the operation. Long-term survival was not different in elderly patients (5-year rate: 17%) when compared with that of younger patients (18.9%).

CONCLUSION

These data suggest that esophagectomy can be performed safely in selected septuagenarian patients, thus allowing a substantial survival with excellent functional status in a portion of these patients.

[Esophageal prostheses in cancer stenosis. Insertion with the Dumon-Gilliard device. 342 patients]

Endoscopic placement of an oesophageal prosthesis rapidly brings a satisfactory comfort to patients with cancer of the oesophagus beyond the therapeutic stage. When the least traumatic technique and materiel are used, the procedure is simple and safe, irrespective of the patient's general condition and the extent of local or regional lesions. The present possibility to insert, at the same time, a tracheobronchial prosthesis broadens the indication to patients who have an oesophagus-airway fistula or who suffer from compression of the trachea or the left bronchus. The procedure is performed under general anaesthesia at the expense of a short hospital stay which is always appreciated by this type of patients. The author's 10-year experience of oesophageal prosthesis placement with the Dumon-Gilliard applicator, is reported.
