Levels of the tumour markers CEA, CA 19-9, CA 125 and SCC were measured in 58 patients presenting with oesophageal carcinoma and compared with levels in patients with benign oesophageal disease and levels in normal volunteers. CEA and CA 19-9 were significantly increased in the patients with oesophageal cancer, however, individual sensitivity for CEA, CA(More)
Surgical site infection (SSI) is an infection occurring in an incisional wound within 30 days of surgery and significantly affects patients undergoing colorectal surgery. This study examined a multi-institutional dataset to determine risk factors for SSI following colorectal resection. Data on 386 patients who underwent colorectal resection in three(More)
Tumor necrosis factor (TNF) is a cytokine that mediates many of the metabolic responses after endotoxemia, septicemia, and tissue injury. The effect of TNF on testicular function was determined in a series of studies in which rhTNF (0, 2, and 4 X 10(5) units/kg/24 hours) was administered by continuous infusion to male Wistar rats maintained on total(More)
Entrapment of the lateral cutaneous nerve of the thigh (LCNT) is a recognized complication of laparoscopic hernia repair. In our first 10 patients in a series of 30 laparoscopic herniorrhaphies we encountered two cases of meralgia paraesthetica, leading us to review our surgical technique and analyze the local anatomy in 20 LCNT cadaver dissections. The(More)
BACKGROUND Surgical site infection (SSI) is an infection occurring in an incisional wound within 30 days of surgery and significantly effects patient recovery and hospital resources. OBJECTIVE This study sought to determine the relationship between preoperative serum albumin and SSI. METHODS A study of 524 patients who underwent gastrointestinal surgery(More)
Acute whiplash injuries are a common cause of soft tissue trauma for which the standard treatment is rest and initial immobilisation with a soft cervical collar. Because the efficacy of this treatment is unknown a randomised study in 61 patients was carried out comparing the standard treatment with an alternative regimen of early active mobilisation.(More)
Glutamine (GLN) is an important fuel and epidermal growth factor (EGF) is a potent mitogen for intestinal mucosa cells. GLN-enriched parenteral nutrition was administered to male Wistar rats, and subcutaneous injections of EGF were given for 3, 6, and 7 days. Control animals were fed a non-GLN-containing solution. Other groups of animals received GLN or EGF(More)
BACKGROUND With increasing antibiotic usage Clostridium difficile colitis is becoming more common. Surgery for fulminating C. difficile colitis, however, is rare because of the effectiveness of specific anticlostridial chemotherapy. Surgical outcome in five patients with fulminating C. difficile colitis involved in a recent outbreak of this disease is(More)
The proinflammatory cytokines play a central role in mediating cellular and physiological responses, and levels may reflect immune system effectiveness. In this study, the effect of ageing on the inflammatory response was examined using a novel method to detect production of the proinflammatory cytokines, i.e. tumour necrosis factor-alpha (TNF-alpha), IL-6(More)
To determine whether mechanical bowel preparation influences the incidence of anastomotic dehiscence following colorectal surgery, 186 patients undergoing elective left colonic or rectal resection were randomized before surgery to bowel preparation (n = 89) or no bowel preparation (n = 97). Surgical technique was standardized and no patient had a(More)
