Diaphragmatic relaxation is a pathology not frequently observed because it is generally oligosymptomatic. The development of modern technology has induced an important contribution to the diagnosis and treatment of the disease which can find a possibility of restoration in surgery. A 63-year-old patient with a light syndrome of respiration deficiency and an altered relaxed profile of the right cupola was subjected to surgical treatment with the technique of diaphragmatic plicature without any adverse implication during and after the operation. After a brief recovery, the patient was discharged and after 9 years he affirmed still absence of dyspnoea from limited labor and absence of respiration problems. The selected surgical technique for the restoration of the altered muscle is the diaphragmatic plicature without incision or excision of the altered part of the muscle. The preferable access way today is that of laparotomy which is devoid of problems of thoracotomy and generally it permits quite easily the restoration of all diaphragmatic defects. Diaphragmatic plicature is a simple, effective and long-lasting intervention but we cannot determine the complete recovery of the normal contractile function of the muscle. There is no morbidity and mortality directly related to this technique, the latter incidentally associated with complications of general anesthesia.

Bariatric surgery for the treatment of morbid obesity or overweight refractory to medical therapy was born at the beginning of second half of the twentieth century, and its first steps were uncertain and with a not jet well definite purpose. In fact the main result to be pursued seemed to be simply the reduction of body weight, and any change of anatomy of the digestive tract able to reduce the absorbtion of nutrients was judged adequate. But very early the adverse consequences of malabsorption so obtained became evident, and other operations possibly free from those complications were devised and clinically tested. So aside the by-pass operations many other surgical procedures found their room, all of them aiming to fight the ever more diffuse obesity of the people. This historical review of the various surgical procedures attempted in these last sixty years for morbid obesity is very interesting for a better understanding of the problem and to have a solid basis for future rational choices.

The Roux-en-Y recostruction after total or subtotal gastrectomy for gastric cancer is frequently performed to prevent esophageal alkaline reflux. Also after total gastrectomy and end-to-side gastrojejunal anastomosis, as usual in former experience, the alkaline reflux can be efficaciously treated by conversion in an esophago-jejunal Roux-en-Y procedure. The main factor preventing reflux is the length of jejunal loop, at least of 35-40 cm. The recostruction with a Roux-en-Y jejunal loop offers the advantage to meet together two primary requirements: the restoration of digestive travel from esophagus to intestine, and the prevention of on alcaline reflux esophagitis, both with relevant simplicity and without a time-consuming surgical technique. Also as a consequence the postoperative morbidity is decreased. The obvious suitable requirement is a sufficient lenght of the jejunal loop for a reservoir of the ingested food and to oppose the antiperistaltic jejunal movements thanks to the effects of the new activated jejunal pace-maker.

The grasping tie is an original and mechanical tool, conceived and planned to be used in digestive surgery to do the equivalent of a purse string. Its use is conceived to make easier the mechanical anastomosis in the more difficult situations as the oesophago-jejunal or the very low colo-rectal ones, as in the example of the presented paper. A thin ribbon of nylon will be progressively tightened as a one-way running knot upon the tract of the gut, either directly or about the axis of a circular stapler. Once completed the stapler suture it will be completely extracted together with the muscle-mucosal rings, so that nothing of the ribbon remains in the patient. The use of the grasping tie is also advantageous in quickly closing the gut above and below a tumour, to a safer manipulation and to reduce the contamination of the operative field. An original and useful use of the grasping tie is demonstrated in the present paper for the surgical treatment of a low rectal cancer with preservation of the anus. Its use is that to close the distal stump of the rectum below the tumour, to take away from the pelvis the proximal stump with the tumour, and then to proceed to the mechanical anastomosis in a now wide operatory field, introducing in the anus an enteral dilator and preparing on it the definitive purse string, as illustrated.

The Argon Beam Coagulator has gained his space in surgery thanks to its operative characteristics, that are very useful in sealing the bleeding parenchymal tissue with minimal injury to the surroundings. The aim of the present study is that of evaluate the physical properties of the instrument in its coagulation action. The experimental study with the Birtcher 6000 Argon Beam Coagulator has been designed to measure the top temperature that develops right where the Argon beam meets the tissue, while operating. Using a laser guided telethermometer, the searching of that temperature was uneasy right on the operatory field because of the unwilling movements of the operator hand and those of the patient himself. Therefore a similar protocol was made on a piece of meat coming from the butcher. At the longest application of the beam coagulation on the same point the developed temperature was never higher than 100 degrees C whilst a complete coagulation effects. The advantage of the Argon Beam coagulation are therefore to seal the diffuse bleeding without injury to this adjacent tissues, never exposed to a temperature higher than that of boiling water. The advantages are also evident in comparison with the more usual spray electrosurgery that is instead characterized by a wide carbonisation also with this spray option.
