The number of amputations performed for vascular disease in Denmark has decreased from 1777 (34.5 per 100,000 population) in 1983 to 1288 (25.0 per 100,000) in 1990, a reduction of 28 per cent. This decline coincided with an increase in vascular surgical activity of up to 100 per cent, including a marked rise in the rate of femorodistal reconstruction. ⋯ The relative number of above-knee amputations also decreased in favour of more distal levels during the period studied. These findings suggest that vascular surgery may be responsible for the lower amputation rate.

Randomized Controlled Trial Clinical Trial
Closure of midline laparotomy incisions with polydioxanone and nylon: the importance of suture technique.
The healing of midline laparotomy incisions closed with a continuous suture of nylon or second-generation polydioxanone was evaluated in a randomized clinical trial. The effect of suture technique, reflected in the suture length to wound length ratio, was also assessed. All patients who underwent abdominal surgery through a midline incision were included except those with incisional hernia after previous midline operation. ⋯ There was a significant correlation between the hernia rate and the suture to wound length ratio for both materials (P < 0.001). These results indicate that suture of midline laparotomy wounds is as safe with polydioxanone as it is with nylon. Incisional hernia is associated more with suture technique than with the material used.

Of 176 patients with carcinoma of the pancreatic head region 156 underwent standard pancreatoduodenectomy (group 2) and 20 with macroscopic suspicion of invasion of the portal vein or superior mesenteric vein (SMV) underwent pancreatoduodenectomy with partial resection of the portal vein or SMV (group 1). In 16 patients in group 1 end-to-end anastomosis was used for reconstruction of the vein. The morbidity rate in groups 1 and 2 was similar (55 versus 63 per cent). ⋯ The median survival time after resection of the portal vein or SMV was 8 months; the 2-year survival rate was 19 per cent. Comparison of survival in group 1 with survival in subgroups of patients undergoing standard pancreatoduodenectomy, matched for all histological parameters, showed no significant difference. It is concluded that partial resection of the portal vein or SMV in patients undergoing pancreatoduodenectomy who are suspected of having tumour invasion of the portal vein or SMV does not improve either the rate of curative resection or survival.

Forty-nine patients with chronic obscure groin pain, bilateral in four, presented to one general surgeon in a 12-month period. Inflammation ('enthesopathy') at the pubic insertion of the inguinal ligament was the cause in 30 patients (32 groins). This has not previously been recognized as a cause of chronic groin pain, possibly because the exact site of tenderness can be obscured by the pubic pad of fat. ⋯ Inguinal hernia is sometimes coincidental rather than causative of the pain. In three patients the pain had subsided and no diagnosis was made. Simple diagnostic and therapeutic measures may relieve chronic groin pain and spare patients elaborate investigation or unnecessary operation.

Received wisdom commends a policy of maximizing the ratio of below-knee to above-knee amputations in patients with end-stage arterial disease. After adoption of this policy, the long-term outcome of 100 consecutive lower-limb amputations in 96 patients was monitored by annual review for 5 years. The ratio of primary below-knee to above-knee amputations was 2:1, with 9 per cent of below-knee amputations undergoing revision to a higher level. ⋯ Although the below- to above-knee ratio in 1984 was only 1:2, the overall rehabilitation rate, as determined by the proportion of patients able to walk at 2 years, was 34 per cent. It is concluded that increasing the proportion of below-knee amputations from one-third to two-thirds of lower-limb amputations for occlusive arterial disease does not improve effective rehabilitation rates. Received wisdom on the desirability of a high below- to above-knee ratio may be wrong.
