ABSTRACT

BACKGROUND: Colorectal cancer (CRC) has the second highest mortality rate of all cancers in Ireland. Developments in imaging, surgical technique, and perioperative care in the last two decades have altered management. AIMS: To determine whether outcome following surgery for CRC in the mid-west has changed over a 22-year period. METHODS: Four hundred and twenty-two patients were divided into two time periods: Group A (1980-1991, n = 203) and Group B (1992-2002, n = 219) and demographic, inpatient, and survival data were reviewed. RESULTS: The mean age was 67 years, 59% were male. Group B patients had less advanced disease at presentation (Dukes' stage D 14% vs 22%, p < 0.05), fewer perioperative complications (13% vs 23%, p < 0.05), and fewer local recurrences (6.8% vs 11.8%, p < 0.05) than Group A. No difference in 30-day mortality rate or survival was detected. CONCLUSIONS: Although perioperative CRC management has improved, methods of earlier diagnosis and improvements in adjuvant therapy should be explored to improve survival.

ABSTRACT

BACKGROUND: Contralateral groin exploration in children with unilateral inguinal hernia is still controversial, particularly in infants. The patency rate of processus vaginalis is highest in infants but there are few data on the subsequent risk of contralateral hernia development in infants. In this retrospective study, we aimed to find out the incidence of contralateral inguinal hernia following unilateral inguinal herniotomy in infants aged less than one year. METHODS: All infants who underwent a unilateral Inguinal herniotomy between January 1990 and December 1998 were studied retrospectively. Infants with bilateral hernia (n = 7) were excluded from the study. RESULTS: One hundred and one infants (93 boys and 8 girls) were studied. Median age at operation was 23 (range 2-52) weeks. The herniotomy was right-sided in 75% of the infants. Follow-up ranged from three and a half years to 11 years. A contralateral hernia developed in nine infants (9.0%). One of the initial hernias was incarcerated. Median time from operation to occurrence of contralateral hernia was 18 (range 2-60) months. None of the contralateral hernia was incarcerated. Age, sex, incarceration and side of initial hernia did not influence the development of contralateral hernia. CONCLUSION: The low incidence and benign nature of contralateral hernia development in infants undergoing a unilateral inguinal herniotomy does not justify routine contralateral groin exploration.

ABSTRACT

BACKGROUND: Laparoscopic cholecystectomy is associated with an increased conversion rate in acute cholecystitis. AIM: To review the operative management of symptomatic cholelithiasis with particular reference to conversion rates and morbidity for laparoscopic cholecystectomy for acute cholecystitis. METHODS: Patients undergoing cholecystectomy between January 1994 and December 1998 were recruited. Demographic details, diagnosis, duration of symptoms, treatment, outcome, post-operative stay and complications were recorded. RESULTS: Complete data were available on 482 patients (84%). Laparoscopic cholecystectomy was attempted in 120 of 132 patients (91%) with acute cholecystitis and 329 of 350 patients (94%) with non-acute gallbladder disease. Conversion rates were 27% (33/120) and 6.7% (22/329) for acute and non-acute gallbladder disease, respectively (p < 0.001 chi2 test). Relating the interval from onset of symptoms to surgery, conversion rates for acute cholecystitis were: < 3 days, 5/17 (29%); 4 to 42 days, 14/59 (23%) and > 42 days, 14/44 (31%). There were three bile duct injuries, two in the delayed (> 45 days) acute group and one in the non-acute group. CONCLUSION: Early laparoscopic cholecystectomy is the treatment of choice for acute cholecystitis, but is associated with a high conversion rate independent of the timing of surgery.

ABSTRACT

BACKGROUND AND AIMS: There is a lack of consensus regarding the role of CD44 variants in colorectal cancer, with conflicting reports regarding their expression and correlation with prognosis. We investigated the expression and prognostic significance of CD44v6 protein in our series of colorectal tumour specimens and then analysed the pattern of CD44 variant mRNA transcript expression in a smaller series of colorectal tumour/normal tissue specimens, thus assessing what our data contributes to this debate. METHODS: Immunohistochemistry was used to detect CD44v6 protein expression, while reverse transcriptase-polymerase chain reaction in combination with Southern blotting was used to analyse CD44 mRNA transcript expression. RESULTS: Similar levels of expression of CD44v6 protein were observed in each of the Dukes' stages, ranging from 50% to 67%, indicating no correlation with progression of disease or survival rates. CD44 variant mRNA expression was found in 85% of the tumours and 75% of the normal specimens. The majority of tumours expressed each of the variants. The pattern of variant expression was maintained in the corresponding normal tissue in nearly one-half (47%) of the tumour specimens. A sequential pattern of variant expression was observed in the majority of specimens. There was no association between CD44 variant mRNA expression and Dukes' stage, tumour differentiation or survival. CONCLUSIONS: The data reported here, along with those already in the literature, suggest that CD44v6 does not play a pivotal role in colorectal cancer progression. Moreover, due to the pattern of expression of contiguous blocks of variant transcripts it is unlikely that expression of any single variant can predict outcome in vivo.

ABSTRACT

BACKGROUND: Laparoscopic cholecystectomy is the operation of choice for cholelithiasis. AIMS: The aims of our study were to assess the feasibility of day case laparoscopic cholecystectomy (DCLC) in selected patients. METHODS: DCLC was introduced in this unit in July 1999. The first 50 patients were prospectively evaluated up to February 2001. RESULTS: All patients were under 55 years of age with an ASA grade of I (n = 48) or II (n = 2). The mean age was 41.1 years (range 20-55 years) and the male:female ratio was 1:6. All patients had a standard anaesthetic protocol. Patients were discharged 10 to 12 hours postoperatively with a pro forma, which was reviewed at one week in the clinic. The conversion rate was 2%. Three required overnight admission due to excessive nausea, hypertension and for an unforeseen psychosocial problem. Ninety per cent of patients were suitable for same day discharge. No patient required subsequent readmission. CONCLUSION: DCLC is feasible and safe in carefully selected patients and has the advantages of convenience and cost-effectiveness.

ABSTRACT

BACKGROUND: In Ireland, general surgeons provide paediatric surgical services to patients remote from specialist paediatric units. AIM: To review general paediatric surgical services in the Mid-Western Health Board (MWHB) region with a view to informing future policy decisions in Ireland. METHODS: From 1995 to 2000, the paediatric surgical workload at the Mid-Western Regional Hospital was reviewed. Operations performed, level of operating surgeon, morbidity and mortality were recorded. RESULTS: There were 3,166 general paediatric surgical patients cared for by three general surgeons and one urologist, all with paediatric surgical training. There was an increase in day cases (55% to 70%) and operations at which the consultant was the main operator (40% to 67%). There was no mortality and the morbidity rate was less than 1%. CONCLUSIONS: General paediatric surgery and urology is well provided for in the MWHB by appropriately trained surgeons. Lack of opportunity for surgeons in training to obtain general paediatric surgical experience will put this service at risk as the current cohort of surgeons retire. Expansion in specialist paediatric surgical services, changes in general surgical training to include general paediatric surgery or proleptic appointments may be required.

ABSTRACT

BACKGROUND: It has been suggested that only specialist paediatric surgeons should manage infantile hypertrophic pyloric stenosis (IHPS). AIM: The aim of this retrospective study was to ascertain whether the majority of these infants might be managed in a well-equipped regional centre. METHODS: Using the Hospital Inpatient Enquiry database, all cases of IHPS within a single administrative health region were identified over a six-year period. A chart review was performed to obtain demographic and clinical information for each patient. Reports from the Central Statistics Office were used to obtain data on population and live births for the region. RESULTS: Seventy patients with IHPS were identified from this region from 1991 to 1996, 63 (90%) of which were treated in the region. Of the remaining seven, four were referred directly to specialised paediatric surgical hospitals because of prematurity (n = 1), low birth weight (n = 1), capillary haemangioma (n = 1) and severe metabolic derangement (n = 1) while three were assessed and treated in general hospitals outside the region. Of the 63 infants undergoing pyloromyotomy in this region, the duodenal mucosa was breached in four (6%); there were wound complications in three (5%); and one required a re-pyloromyotomy. The mean postoperative stay was eight days (range 2-42 days). CONCLUSION: The majority of infants with IHPS may be safely managed in regional centres with transfer to specialist paediatric centres reserved for 'high risk' cases. The management of IHPS at a regional level has important implications and presents opportunities for surgical training.

ABSTRACT

A series of 127 consecutive patients with symptoms and signs and radiological features suggestive of acute small bowel obstruction underwent water-soluble contrast small bowel follow-through examination. A dose of 100 ml of Gastrograffin in adults, or 20-50 ml in children, was injected via a nasogastric tube and supine plain abdominal radiographs were taken at 30 min and 4 h after administration. If contrast passed to the colon a non-operative course was followed. If there was a clear cut-off in contrast level in the small bowel or if contrast failed to pass into the large bowel by 4 h, patients underwent laparotomy. Based on these radiological findings 15 patients (11.8%) underwent surgery and all had established small bowel obstruction at laparotomy. The remaining 112 patients were successfully managed conservatively. Water-soluble contrast radiology is safe, easy to use and to interpret, and is a major benefit in differentiating mechanical from other causes of small bowel obstruction. Our experience indicates that this underused technique is of significant value in identifying those patients who require urgent surgery.

ABSTRACT

There are many concerns about the widespread introduction of laparoscopic cholecystectomy. The initial experience of five hospitals in introducing laparoscopic cholecystectomy was reviewed. Three hundred and eight patients were operated upon, and the operations were completed laparoscopically in 279 (91 percent). One patient sustained a diathermy injury to the right hepatic duct. There was no mortality and the overall morbidity was 10 percent. Mean postoperative stay was 3.6 days. The participating surgeons considered training workshops to be desirable and felt that trainees should be supervised for at least ten cases. Laparoscopic cholecystectomy can be safely introduced and performed, and it should be considered in all patients undergoing cholecystectomy.

ABSTRACT

To identify patients with common bile duct stones, all patients considered for laparoscopic cholecystectomy in this unit undergo intravenous cholangiography (IVC) with tomography and, more recently, operative cholangiography. To date 100 consecutive patients with symptomatic gallstones have undergone laparoscopic cholecystectomy with no specific exclusion criteria. Eight patients of 100 were found to have duct stones on IVC with one false-positive. These IVC data were compared with data from 52 patients who also had operative cholangiograms performed. One stone was detected on operative cholangiography that was not identified on IVC. No additional information was gained from operative cholangiography. These data suggest that preoperative IVC is adequate for the detection of duct stones in patients considered for laparoscopic cholecystectomy.

ABSTRACT

Gastro-enterostomy produces variable and often disappointing results in the management of duodenal obstruction due to advanced pancreatic carcinoma. In a series of 51 patients who had palliative surgery for carcinoma of the pancreas five required a gastro-enterostomy. Three of these subsequently had difficulty with gastric emptying. The problem of gastro-enterostomy failure in palliation of pancreatic carcinoma is discussed.

ABSTRACT

This retrospective study aimed to determine why the incidence of strangulated hernias in adults remains high. Seventy-nine patients presented with clinical evidence of hernia strangulation which required urgent surgery during the period 1979-87. Forty-six patients (58 per cent) had noted a hernia present for at least 1 month before strangulation: 18 (23 per cent) had not reported it to their family doctor, 19 (24 per cent) were known by family practitioners or non-surgical medical personnel to have a hernia but had not been referred for surgical opinion, and nine (11 per cent) had been previously assessed surgically with a view to elective repair. Of these nine, five were considered unfit, three were on waiting lists for operation and one had refused surgery. Thirty-two patients (40 per cent) presented primarily with strangulation within days of developing a hernia. The duration of hernia before strangulation in one patient was unknown. Although an unavoidable number of patients will continue to present with strangulation within days of developing a hernia, the overall incidence could be significantly reduced by greater public awareness of the risks of hernia strangulation and by a policy of immediate patient referral and prompt elective repair.

ABSTRACT

In a prospective study of 108 intravenous infusions a significant decrease was noted in the incidence of both cannula-related sepsis and cannula-related phlebitis in those patients on low dose (1000 units/1000 ml infusate) heparin given intravenously. A significant decrease in the incidence of cannula-related phlebitis was also noted in patients receiving subcutaneous low dose heparin (5000 units 8-hourly). This significant decrease may be due to inhibition of fibrin clot formation around the tip of the indwelling intravenous cannula.

ABSTRACT

Leucine and methionine enkephalins were measured by biological assay in normal colon, adenocarcinoma of the colon, carcinoma of the caecum, and in normal and inflamed appendix. Methionine enkephalin levels in both the adenocarcinomas and inflamed appendices were significantly higher than in normal controls. No significant change occurred in leucine enkephalin levels. The caecal tumours were anaplastic and contained no demonstrable opioid activity.
