Non-operative management of perforated duodenal ulcer.

We describe the selective non-operative management of 34 patients who had an initial diagnosis of perforated duodenal ulcer made on acute presentation between 1984-1994 in our district surgical unit. Diagnosis of the condition was made on clinical grounds with the aid of an erect chest X-ray which demonstrated pneumoperitoneum in 28 patients (82 per cent). Six patients (18 per cent) who did not respond to non-operative treatment required surgical intervention; 3 patients had an unsealed duodenal ulcer perforation; 2 had a perforated benign gastric ulcer and 1 patient had acute gangrenous cholecystitis. The overall mortality and morbidity rate was 3 per cent and 35 per cent respectively. There were no documented reperforations over a mean follow-up period of 27 months. While these figures are acceptable and comparable with operative intervention for this condition, we do however stress the labour intensive methods and close clinical monitoring that is required to avoid morbid sequelae.

Changing trends in acute peptic ulcer surgery in a district surgical unit.

Despite changes in management and the advances in therapeutics, surgeons are still required to treat the complications of peptic ulceration. A retrospective review of all open surgical interventions for complications of peptic ulcer disease between January 1983 and December 1993 was carried out. There were no exclusion criteria. Open gastric surgery accounted for 3% of all inpatient surgical procedures and 13% of all the major operations. There were 341 adult and 132 paediatric procedures performed in the 11 year period. Acute gastric procedures accounted for 34% of major gastric surgery in this district unit. 76 perforated ulcers and 39 bleeding ulcers required surgery. 38% of the patients were over 70 years. The perioperative mortality was 13.9% (4% for those under 70 years). The overall morbidity rate was 71% and procedure-related morbidity rate was 17%. Acute gastric surgery has a very high inpatient morbidity and is associated with a significant mortality particularly in elderly patients.

Intensive care in an Irish district general hospital--a three year review.

The International Missionary Training Hospital is a 340-bed acute general hospital with maternity and paediatric units. It serves a population of 120,000 people within the North Eastern Health Board Area and has approximately 14,000 admissions each year. This report retrospectively reviews the activity of a three bedded, Intensive Therapy Unit (ITU) over the three year period July 1987-June 1990. 805 patients (1.9% of hospital admissions) with an average age of 55 +/- 22 years (mean +/- SD, range 14-94 years) were admitted to the unit. There were 458 males (57%) and 347 females (43%). 68% of the patients were admitted from the general wards and the remainder from the accident unit. 59% of the admissions were immediate postoperative cases. 82% of patients had APACHE scores less than 20. There was a wide diversity of medical and surgical diagnoses requiring treatment. 219 cases required one or more systems to be supported and 586 (73%) were admitted as high dependency cases. For those requiring ventilation, the average ventilation time was 3.2 days (range 0.5-23 days). The average length of stay within in the unit was 2.3 days (range 1-23 days). 86% of the patients were discharged to the wards, 11% died and 3% were transferred to external specialist care facilities. ITU's in district general hospitals serve as both critical care areas and high dependency units. In our opinion they produce a positive contribution to progressive patient care for high risk medical and surgical patients.

A review of the nature and activity of a general surgical service in Ireland.

The steady increase in hospital costs has led to demands for closer scrutiny of activity levels, workloads and outcomes. This study sought to examine these parameters in a typical district general surgical unit in this country. In the five year period 1985-89, 11,227 inpatient and 3,354 outpatient procedures were performed; 83% of the inpatient procedures were elective and 17% were emergency surgical operations. All inpatient procedures were categorized: minor (41%), intermediate (42%) and major (17%). A prospective one year review in 1990/1991 confirmed the accuracy of the retrospective data. During that year 2,335 inpatient operations and 765 outpatient operations were performed, of which 80.5% of the inpatient operations were elective and 19.5% were emergency procedures. Of these 16.6% were major, 34.4% intermediate and 49% were minor operations. 60% of the operations were performed by consultants. The in-hospital surgical mortality for the 1 year prospective review was 1.35% and the perioperative mortality was 0.64%. The overall operation morbidity rate was 9% and the procedure-related morbidity was 4.7%. The wound infection rate was 2%. Of the common operations performed throughout the six year study period appendicectomies and external hernia operations accounted for 20% of the caseload; 14% were urological, 7% were breast and 6% were biliary operations. The average waiting time for elective admissions was less than 4 weeks. The average length of hospital stay and the bed occupancy rates did not change.

Audit of open cholecystectomy in a district general hospital.

This retrospective study audited all non-malignant biliary surgery carried out in a district general hospital between January 1985 and December 1990. Surgery was performed on 722 patients: 555 (77 per cent) were women and 167 (23 per cent) were men. The mean(s.d.) age of the patients was 49(16) years. Elective admissions accounted for 70 per cent of cases and 30 per cent were emergency admissions. Ultrasonography confirmed the diagnosis in 93 per cent of cases. An elective operation was performed in 542 patients and 180 patients underwent an urgent or emergency operation. Simple cholecystectomy was performed on 616 patients (85 per cent); 92 (13 per cent) also underwent common bile duct exploration and 14 (2 per cent) had an additional unrelated procedure. The mean(s.d.) hospital stay was 12.3(6.3) (range 4-34) days. There was one perioperative death. The general overall morbidity rate was 25 per cent and the procedure-related morbidity rate was 7 per cent. For simple cholecystectomy (n = 630) there were no deaths; the general morbidity rate was 15 per cent and the procedure-related rate was 3 per cent.

Surgical audit under scrutiny--a prospective study.

Surgical audit must be shown to improve clinical practice and patient outcome if its widespread introduction is to be enthusiastically embraced by surgeons. Retrospective studies on hospital activity by their nature are often incomplete and unreliable. A 12-month prospective review (July 1990-June 1991) of the activity, morbidity and mortality that occurred within a district general surgical unit is analysed. During the study period, 3,927 patients were admitted to the unit, of whom 1,649 were elective and 2,278 (58%) were emergency cases. 48 patients (1.2%) were transferred to external specialist centres. 41% of the admissions did not require surgery. There were 2,335 in-patient and 765 out-patient operations performed. Using the BUPA classification (n = 3100), there were 388 major (12.5%), 802 intermediate (25.9%) and 1910 minor (61.6%) procedures. There were 15 perioperative and 38 non-operative (27 metastatic carcinoma) deaths. 80% of the perioperative deaths were high risk, elderly patients with acute abdominal pathology. 369 complications (39 in non-operative cases) were recorded among both in- and out-patients: 212 systemic, 133 local/wound and 24 major/life threatening. The perioperative mortality rate was 0.6%. The operative morbidity rate was 9.0% and the procedure-related morbidity 4.7%. The wound infection rate was 2%. In a non-specialist, general surgical unit with a broad case mix, it is possible to provide a standard of care and practice that produces very low mortality and an acceptable morbidity rate.

Surgical emergencies in Ireland. An audit of the emergency surgical caseload of an Irish district general hospital.

Emergency cases are an increasing part of the workload of a general surgical unit. Little accurate quantitative data is presently available on the nature and impact of this workload on a typical district general surgical service. This study reports the results of a prospective one year audit of the emergency cases dealt with by a typical Irish district general surgical service. The general surgical service admitted 2,278 patients acutely, which represented 58% of the total number of admissions to the service. Eighteen patients required immediate transfer for specialist neurosurgical (11), vascular (6) or plastics (1) treatment. Of those cases admitted 1,396 (61.3%) were males and 882 (38.7%) were females. There were 1,786 (78%) adults and 492 (21.6%) paediatric cases. Abdominal pain (48.0%), head injury (23.8%) and urological problems (11.0%) accounted for the majority of the caseload. Within the abdominal pain group, the pre-dominant diagnoses were non-specific abdominal pain (36.0%), appendicitis (19.5%), cholecystitis/obstructive jaundice (10.8%) and peptic ulcer disease (10.0%). There were 456 emergency operations performed, representing 19.5% of all the inpatient general surgical procedures. 328 (72%) of these were performed out of normal working hours. Only 12% of the procedures were major. The commonest operations were appendicectomy (51%), abscess drainage (13%), wound toilet (13%) and laparotomy (11%). The emergency peri-operative mortality was 1.1%. The positive appendicectomy rate was 92%.
