Human tissue reaction to sutures.

Tissue reaction to sutures was studied in 666 specimens obtained from patients from one day to 23 years after operation. Reaction to catgut depends on the stage of absorption and is mainly histocytic in type. Nonabsorbable sutures are encapsulated by a rim of connective tissue, while near the suture histocytes, giant cells and lymphocytes are found. This is most marked with silk and cotton, less so with Dacron, and least with nylon and wire. Tissue infiltration into the suture interstics is variable. The reactions resemble the findings in experimental animals.

Diverticular disease of the colon: surgical perspectives in the past decade.

Review of 475 cases of diverticular disease of the colon emphasized needs to stratify patients into clinical categories. Of 223 cases of diverticulosis coli, had significant colonic complaints which received no attention. Of 198 emergency admissions for acute diverticulitis, only 16 required emergency surgery. Resection in the face of serious peritonitis is not advisable. Twenty-seven elective resections gave excellent results. Three subtotal colectomies were successfully done for major bleeding. Final focus was on determination of therapy groups: medical, surgery advisable, and surgery inevitable.
