[Unusual pathology of the popliteal space. Popliteal artery entrapment].

After reviewing the main anatomical anomalies responsible for the popliteal artery entrapment syndrome, the author emphasizes the need for early diagnosis prior to onset of complications. Whenever confronted with hamstring pain due to sports-related physical stress in a youngster, loss of posterior tibial and pedal pulse should be checked for during static contraction, and then during forced passive stretching of the gastrocnemius muscle; modifications in arterial Doppler tracings during these maneuvers will confirm the diagnosis. Should this fail to occur at this early stage, severe complications will develop in time, manifested primarily by thrombosis of the popliteal artery; ectasia of this artery in itself carrying a risk of further peripheral embolism, thrombosis and rupture.

[Mechanical anastomosis on the second duodenum. Value, technics and indications].

The authors present 50 anastomoses on the second part of duodenum after gastrectomy, that were done for gastro-duodenal ulcer in 24 patients, gastric carcinoma for 20 patients and post-gastrectomy syndromes in 5 patients. The mechanical procedure provide excellent security (without leakage) and was easy to perform. When it is necessary to make the restoration of duodenal continuity, this device is a good technical solution.

[Reversible pyloroduodenal exclusion. Method of temporary protection of the duodenal circuit].

Reversible duodenal exclusion is a technique used to protect difficult duodenal sutures without the problems of permanent exclusion. It is effective throughout the healing period, then disappears when the suture material used for occlusion of the pylorus has been digested by the gastric fluid. Three cases are reported which confirm the usefulness of this technique.

[Colonic occlusions. Retrospective cooperative study of 497 cases].

A retrospective multicenter study involving 12 digestive surgery centers was conducted on 497 cases of colon obstruction. The most frequent cause of colon obstruction was colo-rectal cancer (71 p. cent of cases), but many other etiologies were involved, including 61 cases of torsion and 37 patients with occlusive sigmoiditis. Differential clinical and radiological features in each etiological group are discussed, the results of therapy undertaken analyzed, and a reasonable line of conduct proposed, adapted to each situation, with the objective of attempting to reduce mortality which still affects 25 p. cent of cases operated upon.

[Interposition of dacron meshes through a Pfannenstiel approach for bilateral hernia (author's transl)].

The use of a dacron mesh interposed between the deficient abdominal wall and the peritoneum has proved to be a reliable means of preventing a recurrence. For inserting the material in bilateral hernias, until 1979, the authors used a median supra-pubic incision, in more than 150 patients. Since then they turned to the Pfannenstiel approach in 68 patients. This fashion has the following advantages: -- a better exposition -- a need for less prosthetic material -- no risk of hernia on the incision -- a better post-operative comfort for the patient.

[Pre-operative preparation of the colon: a controlled prospective multicentre study in 215 patients (author's transl)].

Three procedures for pre-operative preparation of the colon were compared during a controlled multicentre study in 215 patients. Though mechanical irrigation with a 10 p. cent mannitol solution is definitely superior as far as the degree of intestinal emptying obtained, no significant difference was noted in the frequency or severity os postoperative infections after conventional preparations by digestive tract irrigation with or without intestinal antibiotics. This method is limited by its tolerance (67 p. cent), its advantages are its rapidity and cost, elective indications being ascending colon lesions with little or no stenosis in young subjects. In other circumstances it has to be compared with the conventional methods of preparation, which should still be employed before operation in subjects who are elderly and/or have moderate to severe stenosis. The addition of antibiotics (neomycin, metronidazole by mouth) reduces the incidence of postoperative sepsis to a marked but non-significant degree, independently of the lesion (cancer, sigmoiditis) and its site. A recent study by F. Lazorthes has led him to prefer an association of antibiotics active against aerobic and anaerobic flora: orally preoperatively, and systemically during surgery.
