Advantages and disadvantages of mechanical vs. manual anastomosis in colorectal surgery. A prospective study.

The merits of mechanical versus manual anastomosis were evaluated in a prospective study of 48 patients undergoing resection of colonic or rectal cancer. The analyzed factors included the time required for construction of the anastomosis, the length of hospital stay, the cost/benefit ratio and complications. The anastomosis was manually performed with monolayer polyglactin 910 sutures in 24 cases and mechanically with an E.E.A. stapler in 24. The anastomosis time averaged 14 min in the suture group and 14.3 min in the stapling group, and the respective hospitalization times were 16 and 17 days. The mean cost was 48,000 lire in the manual, and 200,000 lire in the mechanical group. Four complications occurred in each group. Apart from the cost, no intergroup difference was statistically significant.

A ballistometer for the study of the plasto-elastic properties of skin.

The ballistrometer is based on the "drop impact" of a body onto a stationary surface. A collision in one dimension is provoked by allowing a hard body to drop from a given height onto the skin surface to be tested. After the collision, the impacting body undergoes a variable number of rebounds decreasing in amplitude. By measuring the height of the rebounds, the amount of energy returned by the tissue is calculated in terms of coefficient of restitution e. The equipment, consisting of a hammer unit, a feeder-amplifier, and a plotter, is described. Ballistometry has been carried out on skin areas of 46 normal subjects ranging in age from 8 to 80 years, as well as on pathologic and cadaveric skin. The results show a progressive decrease of e with advancing age, as well as differences related to various skin regions. The tests performed on pathologic skin showed a lowered e in epidermal hyperplasia, hyperkeratosis, sclerosis, and dermal infiltration. An increase of e was observed when a high water content was present in the skin.
