The experience with 142 below-knee amputations for vascular occlusive disease and/or diabetes mellitus in 133 patients has been reviewed. The program utilized Xenon(133) skin bloodflow measurement for the selection of amputation level, emphasized the use of the long posterior skin flap as an important part of surgical technique, and employed immediate postoperative prosthesis with accelerated rehabilitation for postoperative management. The results of this program yielded a 0% postoperative mortality, 89% amputation healing, and 100% prosthesis rehabilitation of all unilateral below-knee amputees, and 93% rehabilitation of all bilateral below-knee amputees. ⋯ A. system was surveyed and a cost analysis, based upon duration of postamputation hospitalization, comparing immediate postoperative prosthesis with conventional techniques, was performed. The savings to the system, taking into account start-up and maintenance costs for a program which employs immediate postoperative prosthesis, was projected to be $80,000,000 over five years. We conclude that a modern amputation program employing Xenon(133) clearance for amputation level selection and immediate postoperative prosthesis with accelerated rehabilitation is well justified based upon reduced morbidity, negligable mortality, and optimum patient prosthetic rehabilitation at a marked reduction in overall cost.

Injuries to the portal vein are rare but have a high risk with a mortality of 50--70% secondary to exsanguinating hemorrhage. When managing injuries to the portal vein, lateral venorrhaphy, end to end anastomosis, or an interposition graft should be attempted whenever possible. However, in a hemodynamically unstable patient or when confronted with a nonreconstructable injury, acute portal vein ligation may be the procedure of choice as it is safely tolerated in some 80% of patients. ⋯ Should portal vein ligation be performed a "second look" operation is essential in 24 hours to examine the bowel for viability. A portosystemic shunt with its inherent complications should not be done as a primary procedure when attempts at reconstruction of the portal vein have failed. Shunting should be reserved for those few patients who develop stigmata of portal hypertension or impending infarction of the bowel.

The complete autopsies of 145 patients dying of colorectal cancer are reviewed. Isolated local or distant metastases are infrequent, compared to disseminated disease. Solitary local recurrences are most common after resection of rectal tumors. ⋯ Two-thirds of the patients with right colon lesions died of liver metastases, and three-quarters of those with rectal tumors succumbed to disseminated disease. The current curative and palliative treatment of recurrent colorectal cancer in clinical medicine by surgery, radiotherapy, and chemotherapy is reviewed. It is suggested that an understanding of the anatomic patterns of cancer recurrence will increase in importance as advances in the modalities of treatment are made,

Analysis of 100 patients receiving HLA identical sibling transplants was performed. Excellent graft survival demonstrated in the group attests to the importance of matching serological determined antigens. ⋯ A particularly striking point that emerges is the potential hazard in incorrectly treating for rejection. Rejection occurs very rarely in these patients; in a patient with deteriorating renal function, etiologies other than rejection should be vigorously sought (including transcutaneous biopsy) prior to initiation of rejection therapy.

Thermal injuries to the hand constitute not only one of the most common burns, but one of the most difficult for the burn surgeon to treat. Early wound closure is mandatory if maximum functional return is to be attained and scarring minimized. Over the last three and one-half years, 60 patients with deep dermal dorsal hand and finger burns were treated by tangential excision and immediate mesh autografting. ⋯ Range of motion in all patients has been excellent and all patients have continued to maintain normal hand function. The cosmetic appearance has been good except for the early "mesh" appearance of the graft which has become less apparent with time. In summary, early tangential excision and immediate mesh autografting of deep dermal dorsal hand burns has fulfilled the following burn principles-preservation of tissue, prevention of wound infection, maintenance of function and early wound closure.
