[Angiographic study of the colonic vessels with a view to esophagoplasty].

Variants of the colic vessels were studied angiographically in 34 cadavers, drawing up an original classification of the colic arteries arising from the lower mesenteric artery. Sixteen variants of the left colic artery were found, which were grouped into five main types, the classical type being encountered in only 22.6% of the cases. In one case the lower mesenteric artery was absent. In coloesophagoplasty better results were obtained with the isoperistaltic transverse colon than with the upper ileocolon in 64% of the cases and similar results in 20%; in 16% of the cases the latter operation was preferable.

[A new concept in esophageal reconstruction with colon (considerations on 329 operated cases)].

The author reports a personal series of 329 cases of coloesophagoplasty from various etiology, the majority of them carried out for corrosive pharyngoesophageal strictures (276), followed by malignancy (44). A personal philosophy is exposed, based on more flexibility in the choice of the type of colic interposition depending on the pattern of blood supply. This mobile policy called "balanced operation" is opposed to the classic rigid approach based on the use of a single procedure in coloesophagoplasty. His choice is the ileocecum with long ileal loop (65 cm), favoring preservation of the ileocecal valve, and confering an antireflux mechanism. In particular cases the cecum may be removed and an ileal graft carried out. If this arrangement is not feasible one should slide toward the left in a clockwise direction performing a left colon interposition (iso- or antiperistaltic). Overall mortality was of 16 cases (4.9%). Morbidity is analysed and different particular arrangements like continuous colic loop, superlong graft, Roux en Y procedure are described. A general outline of pharyngeal reconstruction in corrosive strictures is presented.

The stimulation of fibronectin synthesis by high peak power electromagnetic energy (Diapulse).

The effect of Diapulse therapy (pulsed electromagnetic energy of 27.12 MHz frequency) on post-operative wound healing and plasma fibronectin concentration is investigated. Patients treated with Diapulse, locally and over hepatic area present higher fibronectin levels starting 3d day after surgery. These higher values correlate well with a clear improvement of wound healing processes.

[Surgical management of post-caustic prepyloric stenosis. The Y-V intravascular segmental antrectomy (considerations on 71 cases)].

The author presents 71 cases of gastric stenoses following caustic lesions, of which 20 were located in the stomach and 51 also involved the oesophagus (oesophagian stenosis). In cases with limited antrum stenoses the author performed antrectomy and gastro-duodenal anastomosis. In the pre-pylorus stenoses, when these were located at 3--5 cm from the pylorus the author recommends the conservation of the denevated pylorus by double pylorotomy and anastomosis with the entire gastric section. He describes a personal procedure which he calls: The Y--V intravascular segmental antrectomy". In cases with extensive gastric stenoses (over 75% of the area), as well as in evolutive corrosion lesions the author recommends Y-jejunostomy, of the Maydl type.

[Unusual aspects of colo-esophagoplasty in post-caustic esophageal stenosis].

The author presents 7 cases illustrating various particular aspects of coloesophagoplasty performed in cases of post-caustic esophageal stenoses. In pharyngolaryngeal stenoses the author recommends a personal technical variant of the oro-pharyngeal anastomosis. In one such case he performed a double pharyngocolic anastomosis in "Y". In two cases the author has successfully carried out retro-sternal transposition "of necessity", at 6 months and 4 years after coloesophagoplasty in the pre-thoracic variant. Intra-thoracic strangulation of the colic tube, occuring in two cases at 1 and 3 years respectively following initial surgery was resolved by colectomy of the intra-vascular type ("of verticalization").

[Hemorrhages occurring in reconstructive surgery on the pharynx and cervical esophagus].

The author presents 28 cases of cervical hemorrhages occurring in 235 cervical esophagoplasties (11.9%), generated by the lesion of the transplant vessels or of the vessels of the cervical area. The late postoperative hemorrhages are the most severe ones, often cataclysmic (eight cases with five deaths, 62.5%) being mainly the result of the primitive carotid erosion by a salivary fistula. In two cases the cataclysmic hemorrhage appeared after a simple cervical junction for a benign stenosis, a situation not yet mentioned in the literature. The double ligature of the primitive carotid is the only efficient method. Used in four cases, it was successful in three of them, with a single case of tardy hemiplegia following a rachianesthesia.

[Total duodenal diversion in reflux esophagitis after colic esophagoplasty].

Five patients with severe reflux esophagitis were treated by retrosternal colic esophagoplasty for esophageal stenosis of caustic origin. In 4 cases there was anisoperistaltism and in one case isopersitaltism. Treatment was by antral cologastric anastomosis in all cases, with a undojejunostomy in 3 patients and a colojejunostomy on loop in Y in the 2 others. Mortality was absent and long-term results were very good. Colojejunostomy on loop in Y is a simpler procedure not requiring gastric resection and long-term results were similar. An even less complicated variant of the latter operation that does not require colic section is also described. Prophylaxis of reflux esophagitis after colic esophagoplasty is discussed, the Roux type deviation being proposed for the treatment of cologastric ulcer after esophagoplasty.

[Primary splenic abscess ruptured into the peritoneal cavity (peritonitis in 3 stages)].

The authors present a case with peritonitis following rupture of a splenic abscess in a female aged 18 years. Peritonitis developed in three stages. The diagnosis before surgery was of pelvic peritonitis. Bacteriologic examination revealed the presence of B. colli. Splenectomy was followed by complete recovery of the patient. The site of the primary infection could not be determined. The authors stress the usefulness of exploration of the splenic lodge in the so-called "primary" generalized peritonitis, in pelvic peritonitis or in all cases when the origin of the peritoneal infection is not known.
