Surgical management of carcinoma of the hypopharynx and cervical esophagus.

Between 1975 and 1988 we observed 169 patients with carcinoma of the cervical esophagus, 85 with a carcinoma involving the hypopharynx and the cervical esophagus, and 27 with a carcinoma of the cervical esophageal region that developed after laryngectomy for laryngeal cancer. The mean age of the patients was 57.5 years (range: 41-73). One hundred and sixty-seven patients underwent surgical exploration (operability rate 59.5%), and in 152 cases the tumor was resected (resectability rate 91.1%). The resection was complete in 129 patients (84.5%) and palliative in 23 (14.5%). In 33 cases a laryngopharyngo-cervical segmental esophagectomy with free intestinal loop transplantation was performed, with an operative mortality of 6.1%. One hundred and three patients underwent laryngo-pharyngo-total esophagectomy, and the digestive tract was reconstructed by means of pharyngo-gastrostomy and pharyngo-colostomy in 85 and 16 cases, with an operative mortality of 12.9% and 18.3%, respectively. Total esophagectomy without laryngectomy was performed in 18 patients with a carcinoma of the distal cervical esophagus who refused laryngectomy, with an hospital mortality of 5.5%. The overall 5-year actuarial survival, excluding the operative mortality, was 15.8%. After complete resection, better results were recorded in patients operated on for carcinoma of the hypopharynx than in patients with carcinoma of the cervical esophagus: the 2-year and 5-year actuarial survival was 59% vs. 26% and 43% vs. 17%, respectively. No patient undergoing palliative resection was alive at the 3-year interval.(ABSTRACT TRUNCATED AT 250 WORDS)

[Cancer of the hypopharynx and cervical esophagus. Role and limits of the surgical treatment].

From 1975 to 1988, we observed 169 patients with a carcinoma of the cervical esophagus, 85 with a carcinoma involving the hypopharynx and the cervical esophagus, and 27 with a carcinoma of the cervical esophagus occurring after laryngectomy for laryngeal carcinoma. The average age was 57.5 years (41-73). Exploration was surgical for 167 patients (operability ratio 59.5%), and the lesion was resected in 152 cases (resectability ratio 81.1%). Resection was complete in 129 patients (84.5%) and palliative in 23 (14.5%). A laryngopharyngoesophagectomy involving the cervical esophagus and requiring the transplantation of a free intestinal loop was performed in 33 cases, with an operative mortality rate of 6.1%. Pharyngolaryngectomy with total esophagectomy was performed in 101 patients, and the digestive tract was reconstructed by means of pharyngogastrostomy or pharyngocolostomy (respectively 85 and 16 cases) with an operative mortality rate of 12.9% and 18.3%, respectively. Complete esophagectomy without laryngectomy was performed for 18 patients with carcinoma of the distal cervical esophagus who refused laryngectomy, the hospital mortality rate being of 5.5%. The actuarial survival rate after 5 years (not including operative mortality) was 15.8%. Better results were achieved after complete resection for carcinoma of the hypopharynx than for carcinoma of the cerebral esophagus. The actuarial survival rates after 2 and 5 years were 59% vs. 26% and 43% vs. 17% respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

Esophagovisceral anastomotic leak. A prospective statistical study of predisposing factors.

An esophagovisceral anastomotic leak is a life-threatening postoperative complication, especially in the mediastinum. Of the 242 patients who underwent intrathoracic esophagogastric anastomosis for esophageal carcinoma (182 patients) and adenocarcinoma of the cardia (60 patients) between January 1980 and June 1985, 14 (5.8%) had esophageal anastomotic leakage and two died (0.8%). Various clinical and biologic parameters and aspects of operative technique were studied prospectively and analyzed statistically to identify possible factors responsible for leaks. Both bivariate and multivariate statistical analysis with logistic regression showed that the following clinical and biologic factors do not influence anastomotic leakage: tumor stage, the curative or palliative purpose of resection, neoplastic permeation of anastomotic margins, total protein concentration below 5 gm/dl, albumin concentration below 3 gm/dl, patient's age, diabetes, high blood pressure, cirrhosis of the liver, and cardiac, respiratory, or renal diseases. Technical factors, on the contrary, were statistically significant and of great clinical importance: manual as opposed to mechanical suturing (chi 2 = 8.8, p = 0.013) and single-layer as opposed to double-layer suturing (chi 2 = 9.9, p = 0.043). The level of the anastomosis was found to be a further statistically significant factor: The incidence of leakage was greater when the anastomosis was located between the azygos vein and the lower pulmonary vein (chi 2 = 15.5, p = 0.004) than above the azygos vein or below the lower pulmonary vein.

[Esophageal lesions caused by oral drugs. Epidemiology, physiopathologic bases, prospectives of prevention].

Esophageal injuries caused by oral medications have recently been recognized as a iatrogenic entity. This pathogenesis is due to the retention in the esophagus of drugs with caustic properties. The main predisposing factor is the practice of taking oral drugs with a small quantity of water of and/or in a recumbent position. Elderly subjects and patients with pre-existing esophageal disorders are at higher risk, so that fluid formulations or different routes of drug administration are strongly recommended. A more widespread education to the correct use of drugs and a better drug formulation are necessary for effective prevention.

Adenocarcinoma of the cardia: the choice of surgical treatment.

The ideal surgical treatment for adenocarcinoma of the cardia is still controversial. Out of 168 consecutive patients resected in a 10-year period, 98 underwent esophagogastric resection (EGR) and 70 total gastrectomy with esophageal resection (TGER). Early and long-term results were compared in order to define specific indications for both surgical procedures. Abdominal nodes were metastatic in 62% of the cases; mediastinal nodes were metastatic in 20.3% of 138 thoracotomized patients. Neoplastic permeation of the section margin occurred in 4.7% of the patients. No positive section margins were found in the cases with 10 cm or more of uninvolved esophagus resected. The superiority of the thoracoabdominal approach was therefore evident in terms of oncologic radicality. Anastomotic leakages occurred in 13.3% of EGR and in 7.1% of TGER patients. No correlation between the stage of the tumor or the neoplastic permeation of the section margin and the incidence of leak was found. Operative mortality was 7.1% after EGR and 10% after TGER, which may suggest that EGR is the procedure of choice in poor-risk and elderly patients. Loco-regional or systemic neoplastic recurrence was responsible for long-term mortality in 70% of the cases. Anastomotic recurrence was found in 12.2% of EGR patients and in 1.4% of TGER patients. Overall five-year survival was 19.1%. Mean survival was 29.5 months, 30 after EGR and 27 after TGER (p = NS).(ABSTRACT TRUNCATED AT 250 WORDS)

Anastomosis.

Esophageal anastomosis is still associated with a high rate of complications even though they have decreased considerably in recent years. Anastomotic leaks are more frequent in the neck than in the chest, and related mortality rate is not different. The leakage incidence does not depend on suture materials or on technical modalities used to perform the anastomosis. In fact, there is no difference between the leakage rate when comparing manual and mechanical anastomoses. The leak incidence after both mechanical and manual anastomoses is much higher in collective reviews than in reports coming from leading centers. "Frequent" esophageal surgeons can learn from their previous experience and therefore avoid technical errors, whereas "causal" esophageal surgeons do not have this opportunity. Performing an esophageal anastomosis is a technical matter, and suture healing is independent of the patient's biologic situation. Anastomotic fibrotic strictures are frequent after both manual and mechanical anastomoses, and most can be avoided by meticulous suturing technique.

Surgical treatment of cervical anastomotic leaks following esophageal reconstruction.

Cervical anastomotic leaks occurring in the early postoperative period after esophageal reconstruction are life-threatening complications, with a mortality rate similar to that of intrathoracic leaks if the posterior wall of the anastomosis is affected. Prompt diagnosis and aggressive surgical treatment is vital. The surgical procedures commonly used are often inadequate or unsatisfactory because of the difficulties encountered in the subsequent reconstruction. Twelve patient with an early cervical anastomotic leak following elective esophageal surgery were treated using an original surgical technique which allows diversion and simple delayed reconstruction of the anastomosis without risk of late stricture. Uncontrolled mediastinal sepsis accounted for the three deaths of the series and occurred in patients with a leak of the posterior anastomotic wall in whom definitive surgical treatment was delayed.

Thoracoscopic removal of benign tumours of the oesophagus.

Thoracoscopic excision of an oesophageal leiomyoma was successfully performed in 4 patients. The tumours were enucleated easily without intraoperative complication. A patient in whom the muscular layer was not sutured after removal of the myoma presented with a pseudo-diverticulum one year after the operation and required a thoracotomy for resection. This new procedure which reduces the operative trauma and postoperative pain and allows quick recovery, is described.

Disconnection of the ampulla of Vater: a new technique for reconstruction.

We report the case of a 42 year-old patient who had undergone gastric resection and Billroth I reconstruction for a duodenal ulcer 15 years earlier. The patient was admitted to our Department for a high output biliopancreatic fistula which developed after another gastric resection with Billroth II reconstruction which was performed for a peptic stricture of the gastroduodenal anastomosis. At laparotomy, a complete disconnection of the ampulla of Vater was found, with the duodenal stump oversewn 5 cm distally to the papillary area. After plasty of the biliary and pancreatic ducts, a direct anastomosis between the new ampulla and a Roux-en-Y jejunal loop was performed. The post-operative course was uneventful. The details of the surgical technique are reported.
