Randomized clinical trial of the benefit of laparoscopy with closure of loop ileostomy.

BACKGROUND: The aim was to compare reversal and laparoscopy with standard reversal of loop ileostomy in terms of hospital stay and morbidity in a randomized study. METHODS: Patients having reversal of a loop ileostomy were randomized to either standard reversal of ileostomy or reversal and laparoscopy. Strict discharge criteria were applied: toleration of two meals without nausea and vomiting, passing a bowel motion, and attaining adequate pain control with oral analgesia. Morbidity and cost were also compared between the two groups. RESULTS: A total of 74 patients (reversal and laparoscopy 40, standard reversal 34) with a median age of 61 years underwent loop ileostomy reversal; there were 45 men (61 per cent). Ileostomy was most commonly carried out after laparoscopic low anterior resection (36 patients). Median length of stay, based on discharge criteria, was significantly shorter in the reversal and laparoscopy group than in the standard group: 4 (interquartile range 3-4) versus 5 (4-6) days (P = 0·003). The overall morbidity rate was also lower in patients who had ileostomy reversal and laparoscopy: 10 versus 32 per cent (P = 0·023). The median cost per patient was lower in the reversal and laparoscopy group: €3450 (interquartile range 2766-3450) versus €4527 (3843-7263) (P = 0·015). There was no statistically significant difference in American Society of Anesthesiologists fitness grade or time to reversal between the two groups. CONCLUSION: Reversal of loop ileostomy with laparoscopy was associated with a shorter hospital stay, lower morbidity and reduced cost compared with the standard technique.

Reducing preoperative fasting in elective adult surgical patients: a case-control study.

BACKGROUND: The practice of fasting from midnight prior to surgery is an outdated one. AIMS: The aim of this study was to assess the impact of an evidence-based protocol for reduced preoperative fasting on fasting times, patient safety, and comfort. METHODS: A non-randomised case-control study of preoperative fasting times among adult surgical patients undergoing elective procedures was conducted. Consecutive patients were allocated to a reduced preoperative fasting protocol allowing fluids and solids up to 2 and 6 h prior to anaesthesia, respectively (n = 21). These were compared to control patients identified from an historic study of preoperative fasting times who followed the traditional fast from midnight (n = 29). Fasting times and details of patients' subjective comfort were collected using an interview-assisted questionnaire. Incidence of intraoperative aspirations was obtained from anaesthetic records. RESULTS: Significant reductions in fasting times for fluids (p = 0.000) and solids (p = 0.000) were achieved following implementation of the fasting protocol. Less preoperative thirst (0.000), headache (0.012) and nausea (0.015) were reported by those who had a shorter fast. Intraoperative aspiration did not occur in either group. CONCLUSION: Implementation of this protocol for reduced preoperative fasting achieved an appreciable reduction in fasting times and enhanced patient comfort. Patient safety was not compromised. Further modifications of our protocols are necessary to meet the international best practice. We recommend its implementation across all surgical groups in our institution.

Laparoscopic surgery for complicated diverticular disease: a single-centre experience.

AIM: The role of laparoscopic surgery in the management of patients with diverticular disease is still not universally accepted. The aim of our study was to evaluate the results of laparoscopic surgery for diverticular disease in a centre with a specialist interest in minimally invasive surgery. METHOD: All diverticular resections carried out between 2006 and 2010 were reviewed. Data recorded included baseline demographics, indication for surgery, operative details, length of hospital stay and complications. Complicated diverticular disease was defined as diverticulitis with associated abscess, phlegmon, fistula, stricture, obstruction, bleeding or perforation. RESULTS: One hundred and two patients (58 men) who had surgery for diverticular disease were identified (median age 59 years, range 49-70 years). Sixty-four patients (64%) had surgery for complicated diverticular disease. The indications were recurrent acute diverticulitis (37%), colovesical fistula (21%), stricture formation (17%) and colonic perforation (16%). Sixty-nine cases (88%) were completed by elective laparoscopy. Postoperative mortality was 0%. For elective cases there was no difference in morbidity rates between patients with complicated and uncomplicated diverticular disease. The overall anastomotic leakage rate was 1% and the wound infection rate 7%. There was a nonsignificant trend to higher conversion to open surgery in the elective group in complicated (11.4%) compared with uncomplicated patients (5.2%) (P=0.67). Electively, the rate of stoma formation was higher in the complicated (31.6%) than the uncomplicated group (5.2%) (P<0.02). CONCLUSION: Laparoscopic surgery for both complicated and uncomplicated diverticular disease is associated with low rates of postoperative morbidity and relatively low conversion rates. Laparoscopic surgery is now the standard of care for complicated and uncomplicated diverticular disease in our institution.

A changing trend in the management of patients with newly diagnosed Crohn's disease.

BACKGROUND: Epidemiologic shift with rising incidence of Crohn's disease (CD) has been reported in recent studies. AIMS: To determine disease behaviour and therapeutic interventions undertaken in newly diagnosed patients with CD. METHODS: Patients diagnosed with CD between January 2006 and June 2008 were included. Disease type, location, degree of involvement and type of therapeutic interventions were recorded. RESULTS: A total of 78 patients were included. Colonic, ileo-colonic, terminal ileal and isolated small bowel disease were present in 37, 27, 9 and 5 patients, respectively. Disease phenotype was inflammatory, stenosing and fistulising in 42, 30 and 6 patients, respectively. Surgery was required in 22 patients, including right hemicolectomy (n = 8), subtotal colectomy (n = 4), segmental colonic resection (n = 2), segmental small bowel resection (n = 2), appendectomy (n = 2) and perianal surgery (n = 4). Fourteen patients underwent surgery at the time of diagnosis. Laparoscopic surgery was performed in 14 patients. CONCLUSIONS: A significant proportion of newly diagnosed patients with CD underwent surgical intervention on their first admission to hospital. This may signify a changing trend in the management approach.

Retention of an ingested small blunt foreign body.

Foreign body ingestion is a common problem in clinical practice. Majority of foreign bodies, once passed beyond the stomach, will be evacuated through the gastrointestinal tract within days without any difficulty. Retained foreign body is rare and the objects in question are mostly long, large, or have a sharp end. We report a case of retention of a small, blunt, spherical glass-like object in the ileum of an 87-year-old lady having benefited from a Hartmann's procedure which was incidentally discovered on a computed tomography scan 2 months before its spontaneous evacuation through the stoma.

Demands for vascular access in a renal dialysis unit: implications for a regional vascular unit.

BACKGROUND: The development of regional dialysis units and the expanding indications for dialysis has led to increased demand for vascular access surgery. Consequently, the provision and maintenance of access, and the management of related complications has created a considerable burden on vascular surgical units in hospitals providing renal replacement therapy (RRT). AIMS: The objectives of our study were to review our experience with a variety of vascular access modalities for haemodialysis and to quantify the associated surgical workload. METHODS: We reviewed our experience in a consecutive group of dialysis patients who had access surgery for RRT in a regional hospital setting. RESULTS: Between January 1995 and January 2000, 69 patients entered the long-term dialysis programme in the Mid-Western region (population = 320,000). Of the 158 procedures performed, 138 (87%) were for access creation, and 20 (13%) related to access revision procedures. Twenty patients (29%) developed a total of 30 access related complications. Vascular access procedures accounted for 10% of the vascular surgical workload (1598 procedures) in the five-year period. CONCLUSION: Vascular access is an important part of the haemodialysis services and surgical expertise should be available at local level to cope with likely demand.

The influence of bladder filling on anorectal function.

OBJECTIVE: The aim of this study was to develop a technique to simultaneously evaluate bladder and anorectal function. In particular, this study was designed to determine if anal sphincter resting pressure, anal sphincter squeeze pressure and rectal sensation change with bladder filling. PATIENT AND METHODS: A pilot study of ten female patients who presented to the pelvic physiology unit for assessment of urinary symptoms was performed. All patients completed a symptom questionnaire and quality of life assessment form. Following informed consent a baseline urodynamic test was performed with the bladder empty and subsequently followed by an anorectal manometric test. Changes in anal sphincter resting pressure, squeeze pressure and rectal pressure were recorded over a ten-minute period. With the patient lying in the left lateral position, the bladder was then filled with isotonic saline at room temperature at a constant rate of 30 ml/min. A continuous assessment of changes in anal sphincter resting pressure during bladder filling was made. Anal sphincter squeeze pressure and rectal sensation were measured at fixed intervals during bladder filling (50, 100, 150 ml etc.) and at fixed intervals relative to bladder capacity (25, 50, 75 and 100% capacity) by stopping bladder filling at the appropriate level. RESULTS: There was no significant change in anal sphincter resting pressure (Mean difference(s.d.) between bladder full and empty = 2.7(5.6) P = 0.92*), squeeze pressure (Mean(s.d.) difference = 9.5(26.3) P = 0.86*) and rectal sensation (Mean difference(s.d.) first sensation 10(15.2) P = 0.958; Mean difference(s.d.) urgency = 10(17.8) P = 0.07*) on bladder filling. CONCLUSION: Under normal physiological circumstances, bladder filling does not influence anorectal function. * STATISTICAL ANALYSIS: Wilcoxon signed rank sum test. P < 0.05 considered significant.

Management of head injury in a regional hospital.

BACKGROUND: Concern about delay in the treatment of serious head injury may result in unnecessary transfer to neurosurgical units for scanning and neurosurgical assessment. AIMS: This study assessed the management of head injuries in a regional hospital with computed tomographic (CT) and 'image-link' facilities allowing instantaneous transmission of CT scans to the regional neurosurgical unit for specialist assessment. METHODS: A retrospective study was carried out of all head injuries presenting to Limerick Regional General Hospital in a single year. Data gathered included mechanism of injury, mode of transfer, requirement for admission and length of stay. Neurological status was assessed using the Glasgow Coma Scale (GCS) and functional status using the Glasgow Outcome Scale. RESULTS: Between January and December 1995, 1,564 patients presented with head injuries to the accident and emergency (A/E) department of Limerick Regional General Hospital. Twenty (1%) were dead on arrival, 12% required hospital admission and the remainder were discharged after assessment. Seventy-six per cent were males and 74% under 40 years of age. Among the 194 patients requiring hospital admission, 14% had a skull fracture and 22 had a severe head injury. CT brain scans were performed in 43 patients and were abnormal in 42%. On the basis of CT and clinical findings, six patients were transferred immediately for a neurosurgical procedure and one was transferred later following clinical deterioration. CONCLUSIONS: A CT scan and image-link facility permitting remote neurosurgical advice allows the majority of patients with head injury to be safely managed in well-equipped regional units without onsite neurosurgical expertise.
