[Posterior approach to the rectum. Technic, indications, complications. Apropos of 41 cases].

Certain lesions in the middle part of the rectal ampulla can only be approached with safety through the posterior surface of the rectum after resection of the coccyx and the last part of the sacrum. This approach was employed in 41 patients, with conservation of the sphincter in all cases. Operation was performed 39 times for excision of a large villous tumor, in 1 case for a polycystic lesion, and in 1 case for a localized epithelioma. Extensive tumors in 3 cases required rectal resection with end-to-end anastomosis, employing a circular mechanical suturing apparatus in 1 patient. Two patients died of causes unrelated to the operation, and 5 developed a fistula, three of these cases needing proximal colostomies. Delayed healing of the perineal wound was noted in 5 other patients, residual perineal pain being reported by 2 patients. The posterior approach to the rectum is an exceptional technique, mainly indicated when wide excision of a histologically doubtful tumor cannot be approached from above or below.

[Oesophageal resection for cancer using mechanical suture (author's transl)].

The authors describe a technique of oesophageal resection in which mechanical sutures are used for gastro-oesophageal anastomosis. In the first, abdominal stage, a large gastrectomy is performed, with ligature of the coronary artery of the stomach at its point of origin. The right thoracic approach is then used for gastro-oesophagal anastomosis, which is carried out prior to resection of the cancerous part of the oesophagus, using a TA 90 forceps.

[Papillary and adenomatous polyps of the gallbladder. Clinical, radiological, and anatomical study, and report on 6 cases (author's transl)].

Papillary and adenomatous polyps of the gallbladder are frequently confused with cholesterol pseudotumors. They are rare tumors and are usually diagnosed only after histological examination of a specimen removed at operation. Their course is uncertain and they are potentially malignant lesions, as shown by one of these cases. The frequent association with lithiasis, which in fact can induce malignant changes, is a point in favour of the need for surgical therapy.

[Mechanical sutures in digestive tract surgery: preliminary results (author's transl)].

Intestinal sutures decompose by means of a series of regular steps which can be replaced, from the efficacy, regularity, and rapidity points of view, by a mechanical process. Employing a mechanical suture constitutes a new aspect of digestive tract suturing which requires preliminary training in the use of the method, as strict rules must be followed if a catastrophy is to be avoided. The authors have used different forceps (T.A., G.I.A., and E.E.A.) since 1977, and report the results obtained in 438 patients, including 237 operations for closing visceral sections and 354 anastomoses of all types. An analysis of these results confirms the feasibility and immense value of this new suturing technique.

[Interest and limits of estimation of the carcinoembryonic antigen in colonic and rectal (author's transl)].

An attempt is made to define the usefulness and limitations of carcinoembryonic antigen (CEA) radioimmunoassay for evaluation of diagnosis, tumor resection and detection of tumor relapse in 108 patients with colorectal carcinoma. Preoperative CEA levels were correlated with pathological stage and tumors localisations. Increasing levels of CEA were found with advanced stage of disease (Stage C and D lesions). Our results indicate: 1) that an incomplete drop in circulating CEA level one month after surgery was a bad prognostic sign; 2) that relapses of colon and rectum carcinoma can be detected by increased CEA levels months before the appearance of any clinical evidence.
