Hypertrophic scarring: Dexon suture in a randomized trial.

In a randomized prospective trial of three methods of skin suture an increased incidence of hypertrophic scarring in paramedian and inguinal wounds has been found to be associated with the use of 2/0 Dexon suture subcuticularly. However, the variance associated with the type of suture was less than that associated with the sex of the patient. The patient's opinion of the appearance of the scar was the same for all three suture methods used in skin closure.

"Right" stay in hospital after sugery: randomised controlled trial.

A randomised controlled trial was carried out on 100 patients to compare the effects of discharge after certain pre-specified clinical criteria had been fulfilled--"right" stay--with those of discharge at an arbitrary 10 days after surgery--"fixed" stay. The operations concerned (cholecystectomy and vagotomy) were more hazardous than those previously included in studies of early discharge. Patients in the right-stay group were discharged, on average, 7-6 days after operation--that is, two days earlier than those in the fixed-stay group. In terms of clinical progress, social factors such as return to work, and the acceptability to patients and relatives of the implications of right stay, patients in this group fared as well as those in the fixed-stay group, and in some respects slightly better. Right stay entailed the transfer of some work from hospital to community medical and nursing staff, but this also was acceptable. The concept and use of the right-stay principle is of value in planning the postoperative discharge of suitable patients.

Comparative study of short-term recovery of mental efficiency after anaesthesia.

Two common general anaesthetic techniques were compared to evaluate the time taken for the patient's mental efficiency to recover sufficiently for him to be escorted home after inguinal herniorrhaphy. Recovery in performance efficiency to at least 60% of the patient's own maximum is suggested as a criterion for discharge, and this needs a stay in hospital of seven to nine hours.

Faecal bile-acids and clostridia in patients with cancer of the large bowel.

Of 44 patients with cancer of the large bowel, 36 ( 82%) had high faecal bile-acid concentrations compared with only 15 (17%) out of 90 patients with other diseases. 31 (70%) of the 44 patients with large-bowel cancer had high faecal bile-acid concentrations in the presence of faecal clostridia able to dehydrogenate the bile-acid nucleus, compared with only 8 (9%) out of 90 patients with other diseases. Thes findings support the hypothesis that cancer of the large bowel is caused by high concentrations of bile-acid derivatives produced by certain anaerobic bacteria.

Biliary excretion of diazepam in man.

In a study of diazepam metabolism, diazepam 10 mg was administered i.m. to four patients who had biliary T-tube drainage. Blood and bile diazepam metabolite concentrations were measured for 12 hr. The expected fluctuations in blood diazepam concentrations were seen, and conjugated diazepam metabolites were present in human bile. Bile diazepam concentrations were insufficient to account for an enterohepatic circulation.

Gastric emptying of solid meals after truncal vagotomy and pyloroplasty in human subjects.

Gastric emptying of isotopically labelled solid meals was studied in normal human subjects and in patients at different intervals after truncal vagotomy and Heineke-Mikulicz pyloroplasty. One to four weeks after vagotomy and pyloroplasty gastric emptying was delayed grossly in some patients regardless of the completeness of vagotomy. Patients with gross delay had symptoms of gastric retention. Eight weeks later emptying had returned towards normal and one or more years after vagotomy and pyloroplasty emptying was within the normal range.A subthreshold dose of carbachol injected during the course of emptying of a meal in some of the postvagotomy patients had no detectable influence on the rate of emptying of the meal.
