[Results of resection of locally recurrent rectal cancer].

AIMS OF THE STUDY: The treatment of locally recurrent rectal cancer (LRRC) remains a difficult and controversial issue. The aim of this study was to retrospectively assess the results of an univocal attitude associating resection of a priori resectable lesions using visceral excisions as required, without sacral excision, but including intra-operative radiotherapy (IORT). PATIENTS AND METHODS: Between 1989 and 1999, 32 patients underwent resection for LRRC. Twelve had previously undergone abdomino-perineal excision and 22 had received radiotherapy. Twenty-three patients underwent pelvic exenteration (total in 17, with rectus myocutaneous flap in 18). Twenty-five patients underwent IORT. RESULTS: Three patients (9.3%) died in the early postoperative period and 11 experienced complications (37%). Resections were considered R0 in 6 patients, R1 in 21 patients and R2 in 5 patients. Five-year survival rates, overall and without disability, were respectively 12%, 12% and 5%. Median survivals, overall and without disability, were respectively 22 and 12 months. CONCLUSION: Resection of LRRC remains a surgical challenge. It may achieve an average of one-year survival without disability, and hope for a few cures. Improvement of oncologic results might come from a more accurate patient selection.

[Cleft lip and palate. The semantic conception for informatics. The Cleftor program].

The authors present the creation of a computed programme (Cleftor) which examines the terminology used in the pathology of cleft palates. The malformed anatomy is simplified and superimposed with embryological data. A classification which includes all possible malformation is used. Surgical treatment had also advanced, gestures practised in the past are reviewed and defined to give authors a common basis for discussion when it is time to appreciate results concerning such or such methods or techniques. Thanks to a strict control of facts; the programme gives another idea of the treatment and above all, of the results from that can be called chronic pathology. The Cleftor programme is also a means of communication creating perhaps a supplementary chance of success for a treatment that everyone admits to and considers as always difficult.

[Processing of cephalometry: Delaire's architectural and structural analysis].

This work purpose a performing system for the Cephalometry: Cephor a software for Delaire's analysis. From a radiography, we draw outlines on graphic tablet. Following in a short time, we obtain results: precise diagnosis permitting to establish a care plan. This care plan is indicated on the screen where we can simulate correction from a choised therapeutic (osteotomy for example). Moreover, this soft ware allows to survey numerically and graphically a treatment, allows to use others methods (Tweed, Ricketts, Steiner). Technological advantages rest on a hard gain of time and a precision gain. The large handiness of this system allows reproducible measures easily. Therefore, we own with this software an improvement and a performing system.

[Present status of the Taylor method in perforated ulcer of the duodenal bulb].

Therapy by Taylor's method was attempted in 61 of 96 patients with perforated ulcer of duodenal cap. Treatment was effective in 50 cases (more than 50%) and morbidity and mortality were low. Most operated cases were recipients of simple treatment for the perforation, more rarely combined with therapy for the ulcer disease. Postoperative mortality was very high (24% of patients operated upon) but appeared to be related mainly to associated risk factors. Only 8 of the patients treated by Taylor's method required recovery surgery, while this was necessary in 4 patients operated upon initially and given simple treatment for the perforation. These findings suggest efficacy of Taylor's method for treatment of perforated duodenal ulcer, avoiding operation or allowing treatment of the ulcer disease once the acute episode has passed.

Surgical management of pelvic recurrence from resected rectal cancer: technical aspects.

Management of local-regional recurrences of primary rectal cancer (LRR) by a multi-disciplinary surgical team (GI, urological and plastic surgeons) is presented. Aggressive treatment involving surgical debulking and intra operative radiation can result in local control and long term survival in 10 to 20% of the patients with a low mortality and morbidity. Sequelae caused by the extended surgical resection are limited thanks to the fast healing following omentoplasty associated with musculo cutaneous flaps and to the fashioning of a continent stoma.
