sterile, and the utmost care taken to maintain asepsis 

 throughout the entire proceeding. 



Technic. — Dr. French's method, the simplest and 

 the one giving the most satisfactory results, is as 

 follows: The affected portion of the bowel is pulled 

 up out of the wound and through the slit in the 

 rubber sheeting, and surrounded with the sterile 

 gauze. The operator must then carefully investi- 

 gate the local blood supply and determine which 

 mesenteric vessels can be ligated without danger 

 of obliterating the blood supply to other than the 

 part of the intestin^ to be removed. The branches 

 that supply that portion are then ligated with fine 

 silk. 



One prong of the hairpin is then passed through 

 the mesentery at the upper point of resection, and 

 both are brought transversely across the gut. The 

 other pin is placed in the same manner at the lower 

 point of resection. Both pins are clamped at their 

 free extremities with artery forceps, thus completely 

 obliterating the lumen of the bowel. The intestine 

 is then severed with the scapel, quite close to the 

 clamped prongs of the pin, the incision being ex- 

 tended to the mesentery so as to remove a wedge- 

 shaped portion of it. " The two pins are approximated 

 and tied tightly together. 



Halsted sutures are then placed, starting at the 

 mesenteric attachment. Care mvist be taken that the 

 margins are properly turned in so as to bring the 

 peritoneal surfaces together. Next, the bowel is 

 turned over and the other side sutured in the same 

 manner. The pins are then untied and undamped, 

 severed at their bent ends with the wire cutters, 

 and withdrawn, one prong at a time. The remaining 

 four openings are closed with one stitch each. 

 Finally the incision in the mesentery is closed by a 

 continuous suture.
