Introduction Rings are required to be removed from a finger in many clinical situations. Rings that are difficult to remove is a problem encountered frequently. Many techniques have been reported for this problem. This study looks at the effectiveness of a single technique for removing difficult rings from fingers. Methods A two rubber band technique was used in this study of 69 difficult to remove rings. Success of the technique and time to removal were recorded. Results Difficult rings were removed in 92.5% of cases, in a mean time of 10.7 seconds. No fingers or rings suffered damage during the study. Conclusions This two rubber band technique is a rapid, safe and effective method for removing rings that cannot be removed easily.

A prospective study of 618 patients undergoing elective colorectal surgery performed in a district general hospital over a 10-year period is reported. Multivariate analysis has been used in an attempt to identify risk factors. The risk of wound infection was increased if septicaemia, respiratory sepsis or faecal contamination was present, if the surgeon was a consultant and if increased risk of serious complications if the patient was male and of poor physical status. Operative mortality was significantly associated with poor physical status, respiratory sepsis and intra-abdominal abscess. Only three risk factors could be identified preoperatively: patient gender, physical status and seniority of surgeon. However, procedures low in the pelvis are more difficult and in this study group are also associated with a higher risk of wound infection. The majority of these procedures are performed by consultants. In addition, this study group has proportionally more female patients of poor physical status who are selectively being operated on by the consultant, seemingly indicating the 'consultant' as a risk factor.

A prospective study of 825 consecutive patients with colorectal cancer presenting to three general surgeons in a district general hospital over a 10-year period are reported. In all, 735 patients had an operation and are grouped according to whether their operation was within 24 h of admission (n = 63), more than 24 h after admission (n = 151), or elective (n = 521). Operative mortalities for these groups were 15.9%, 15.2% and 6.5%, respectively, significantly higher in both the emergency groups. Delayed surgery to allow complete resuscitation did not improve the operative mortality when compared with those patients having urgent surgery. Both groups of emergency patients, delayed (27%) urgent (19%), showed poorer 5-year survival than the electively treated patients (36%), many dying of non-cancer causes. Patients who undergo emergency surgery for colorectal carcinoma are more likely to be in poorer physical condition than patients undergoing elective surgery for the same condition. It appears that the physical status is the principal determinant of outcome after emergency colorectal surgery rather than any other factor.

The effect of perioperative blood transfusion on cancer progression remains controversial because retrospective clinical studies have produced conflicting results. We have collected data prospectively on 379 patients undergoing curative surgery for colorectal adenocarcinoma and assessed the effect of variables, including blood transfusion, on survival. Univariate and multivariate survival analysis has been carried out. When the end-point for analysis used was death due to recurrent colorectal carcinoma and non-cancer deaths were censored, there was no difference in cancer-specific survival between transfused and non-transfused patients. Survival analysis was also carried out without censoring the non-cancer deaths and clearly demonstrated how the statistical analysis and data interpretation could be distorted by age-related non-cancer deaths. The incidence of recurrence of colorectal carcinoma was not greater in the transfused group than in the non-transfused group. We conclude that blood transfusion should not be withheld in colorectal surgery for fear of worsening the prognosis.

The use of blood transfusion was examined in 476 patients who underwent curative surgery for large bowel cancer. Of these patients, 128 were not transfused while 348 received a total of 1174 units of blood. A patient was considered over-transfused if the predischarge haemoglobin was more than 12 g/dl. Using this criteria and accepting that single unit transfusions should be avoided, transfusion could have been avoided in 30% of the patients and a total of 377 units were given unnecessarily. Major under-transfusion did not occur; no patient being discharged with a haemoglobin of less than 9 g/dl. This study shows that blood transfusion is overused and the reasons for its use rarely recorded. In view of the morbidity related to transfusion, it is suggested that surgeons and anaesthetists reappraise their transfusion policy and the first step in this must be to record the reason for transfusion.
