[Intraoperative esophageal manometry in the surgical treatment of achalasia].

Since 1985 we have done intraoperative manometry in 54 patients operated for achalasia. Manometry allows the assessment of the completeness of the division of the high pressure zone and ascertain the length of fundoplication (Nissen) as well as its pressure. In 26 patients pH and manometric controls were done postoperatively. Absence of reflux was noted in all and the pressure level after operation was 12.53 +/- 4.94 mmHg. Pressure measurements were not different from those of a group of 15 healthy subjects (15.2 +/- 2.45 mmHg). Dynamic studies of the high pressure zone revealed a post-deglutition relaxation of 72.5 +/- 16.32% over the basal tone. We believe that intraoperative manometry is essential in the surgical treatment of achalasia as it allows a precise control of myotomy as well as the fashioning of a high pressure zone to avoid reflux.

[Results of esophagus extirpation without thoracotomy].

Between January 1978 and May 1988 229 patients have been treated because of malignant and benign conditions of the oesophagus by oesophagectomy without thoracotomy at the Surgical University Hospital "Doce de Octubre" Madrid. 132 patients suffered from oesophageal carcinoma, 68 from carcinoma of the cardia, 9 from carcinoma of the hypopharynx and 20 from different benign oesophageal diseases. Tumor staging and surgical tactics are described. The postoperative mortality was 6.9%, which could principally be put down to respiratory complications (31.2%). The 5-year survival rate of oesophageal carcinoma was 11.9%, that of cardial carcinoma 48.3%.

Results of surgery for cancer of the rectum with sphincter conservation. A randomized study on instrumental versus manual anastomosis.

We present results obtained in a group of patients included in a randomized study from 1979 to 1985 for evaluation of mechanical anastomosis after anterior resection for cancer of the rectum; 113 patients were operated on, 58 with manual and 55 with instrumental anastomosis. There was no significant difference in morbidity or mortality between the groups. The incidence of anastomotic fistulas (clinical and subclinical) was similar (12% vs. 15%), although a large number of tumors in the lower third of rectum was treated by manual anastomosis. Concerning late complications, more stenoses, although mainly asymptomatic, were detected after instrumental anastomosis (15% vs. 6%). The incidence of local recurrence within 3 years was quite similar in the 2 groups (about 15%), and usually occurred in patients who already had generalized disease.

[Surgery of cancer of the rectum].

Surgery of the distal half of the rectum has changed considerably in the last decades; new technical procedures have made possible the conservation of the sphincters in a considerable number of patients. We present the most significant factors of this change in surgical approach. The supporting pilars of the change have been the possibility of automatic sutures (staplers), the reduction of the distal margin and the fact that the rate of complications is similar to that of the abdomino-perineal resection. We review the complications of the surgical treatment (stenosis and fistulas) and the advantages and disadvantages of the instrumental sutures and new surgical procedures.

[Intraoperative cholangiography: its value in simple cholelithiasis].

The present study evaluates the benefits of systematic intraoperative cholangiography (CIO) in 144 patients without preoperative suspicion of choledocholithiasis. Eleven (7.6%) of the intraoperative cholangiographies were considered abnormal by the surgeon and the presence of choledocholithiasis (3/11, 27%) was confirmed in only three cases. Pathology of the main bile duct that had been unsuspected preoperatively was found in only 2% (3/144). We conclude that routine intraoperative cholangiography of patients without preoperative suspicion of choledocholithiasis increases the cost of surgery, prolongs operative time, exposes the patient to radiation and sometimes yields false positives (5%) that lead to unnecessary exploration of the choledochus, which is accompanied by a potential increase in morbidity and a real prolongation of the postoperative hospital stay.
