The Dieulafoy gastric malformation: an under-recognized cause of massive upper gastrointestinal haemorrhage.

The Dieulafoy gastric malformation is a rare cause of upper gastrointestinal haemorrhage. When no obvious bleeding lesion is seen at laparotomy this diagnosis ought to be considered. Three such cases were identified and treated with simple underrunning of the lesion with no mortality and minimal morbidity. Follow-up endoscopy in each patient showed complete healing of the lesion.

Primary adenocarcinoma of the appendix.

Thirteen cases of primary appendicular adenocarcinoma are reported. This rare tumour usually presents as acute appendicitis. The correct diagnosis is rarely entertained before or during surgery. The main treatment choice lies between appendicectomy alone and appendicectomy followed by right hemicolectomy. There are anatomical reasons for advising the latter and survival figures from the literature tend to support this preference. The cases reported here indicate that in the period 1972-1984, in the North West Region, there was a slight preference for appendicectomy alone. The additional procedure of right hemicolectomy did not confer any clear-cut survival advantage.

Early diagnosis in colorectal cancer still no benefit?

Delay to diagnosis from first symptom has been assessed in 332 patients with colorectal cancer treated by the three general surgeons in Trafford Health Authority. Delay was divided into three parts; that due to (a) the patient, (b) the general practitioner and (c) the hospital. There was no significant difference in delay between Dukes stage B and C patients but there was a significant difference in survival at two years between these two stages. Delay for patients with risk factors as family histories or diverticular disease was not significantly different to patients without these factors. When compared to other series delay has been shortened, particularly general practitioner and hospital delay. Fewer patients presented as emergencies and a greater proportion of patients had disease at an earlier stage. However, these favourable aspects are not reflected in an improved survival at 2 years.

Ceftriaxone versus povidone iodine in preventing wound infections following biliary surgery.

The effect of either prophylactic antibiotic or wound antiseptic on bile bacteriology, wound and other postoperative sepsis has been studied in a controlled prospective randomised trial of 243 patients undergoing biliary surgery at a district general hospital. Wound infection rates were significantly less in patients given intravenous ceftriaxone (1%) at induction of anaesthesia when compared to povidone iodine sprayed into the wound at the completion of surgery (9%) (P = 0.02). In all but one patient infected wounds grew organisms identical to those cultured from the bile. There were also fewer chest and urinary infections in the ceftriaxone group but this was not statistically significant.

Are bile bacteria relevant to septic complications following biliary surgery?

Bile bacteriology, wound sepsis and the effect of prophylactic antibiotics have been studied in a controlled prospective double blind randomized trial on 375 patients undergoing elective cholecystectomy at a district general hospital. We have examined the overall prevalence of bacteria in bile and have identified several factors associated with an increased incidence. The identity of organisms isolated from a total of 21 patients with infected wound swabs was compared with isolates from the bile at operation, and in only two instances was there a correlation. Cephazolin, given either pre-operatively, or into the wound, reduced wound infection rates compared with a control group (from 11.8 to 2.4 per cent, P less than 0.005). We conclude that the majority of wound infections in this series were caused by organisms from the patients' skin or exogenous sources, rather than by bacteria from the biliary system.
