Meta-analysis of the effect of perioperative intravenous lidocaine on return of gastrointestinal function after colorectal surgery.

BACKGROUND: Return of normal gastrointestinal (GI) function is a critical determinant of recovery after colorectal surgery. The aim of this meta-analysis was to evaluate whether perioperative intravenous (IV) lidocaine benefits return of gastrointestinal function after colorectal resection. METHODS: A comprehensive search of Ovid Medline, PubMed, Embase, Cochrane library, and clinicaltrials.org was performed on 1st July 2018. A manual search of reference lists was also performed. Inclusion criteria were as follows: randomized controlled trials (RCTs) of intravenous (IV) lidocaine administered perioperatively compared to placebo (0.9% saline infusion) as part of a multimodal perioperative analgesic regimen, human adults (> 16 years), and open or laparoscopic colorectal resectional surgery. EXCLUSION CRITERIA: non-colorectal surgery, non-placebo comparator, children, non-general anaesthetic, and pharmacokinetic studies. The primary endpoint was time to first bowel movement. Secondary endpoints were time to first passage of flatus, time to toleration of diet, nausea and vomiting, ileus, pain scores, opioid analgesia consumption, and length of stay. RESULTS: One hundred and ninety one studies were screened, with 9 RCTs meeting inclusion criteria (405 patients, four laparoscopic and five open surgery studies). IV lidocaine reduced time to first bowel movement compared to placebo [seven studies, 325 patients, mean weighted difference - 9.54 h, 95% CI 18.72-0.36, p = 0.04]. Ileus, pain scores, and length of stay were reduced with IV lidocaine compared with placebo. CONCLUSIONS: Perioperative IV lidocaine may improve recovery of gastrointestinal function after colorectal surgery. Large-scale effectiveness studies to measure effect size and evaluate optimum dose/duration are warranted.

Randomized open-label phase II study comparing oxycodone-naloxone with oxycodone in early return of gastrointestinal function after laparoscopic colorectal surgery.

BACKGROUND: Combined oral modified-release oxycodone-naloxone may reduce opioid-induced postoperative gut dysfunction. This study examined the feasibility of a randomized trial of oxycodone-naloxone within the context of enhanced recovery for laparoscopic colorectal resection. METHODS: In a single-centre open-label phase II feasibility study, patients received analgesia based on either oxycodone-naloxone or oxycodone. Primary endpoints were recruitment, retention and protocol compliance. Secondary endpoints included a composite endpoint of gut function (tolerance of solid food, low nausea/vomiting score, passage of flatus or faeces). RESULTS: Eighty-two patients were screened and 62 randomized (76 per cent); the attrition rate was 19 per cent (12 of 62), leaving 50 patients who received the allocated intervention with 100 per cent follow-up and retention (modified intention-to-treat cohort). Protocol compliance was more than 90 per cent. Return of gut function by day 3 was similar in the two groups: 13 (48 per cent) of 27 in the oxycodone-naloxone group and 15 (65 per cent) of 23 in the control group (95 per cent c.i. for difference -10·0 to 40·7 per cent; P = 0·264). However, patients in the oxycodone-naloxone group had a shorter time to first bowel movement (mean(s.d.) 87(38) h versus 111(37) h in the control group; 95 per cent c.i. for difference 2·3 to 45·4 h, P = 0·031) and reduced total (oral plus parenteral) opioid consumption (mean(s.d.) 78(36) versus 94(56) mg respectively; 95 per cent c.i. for difference -10·2 to 42·8 mg, P = 0·222). CONCLUSION: High participation, retention and protocol compliance confirmed feasibility. Potential benefits of oxycodone-naloxone in reducing time to bowel movement and total opioid consumption could be tested in a randomized trial. Registration number: NCT02109640 (https://www.clinicaltrials.gov/).

Diverticular disease in Scotland: 2000-2010.

AIM: Symptomatic diverticular disease (DD) may be increasing in incidence in western society particularly in younger age groups. This study aimed to describe hospital admission rates and management for DD in Scotland between 2000 and 2010. METHOD: Data were obtained from the Scottish Morbidity Records (SMR01). The study cohort included all patients with a hospital admission and a primary diagnosis of DD of the large intestine (ICD-10 primary code K57). RESULTS: Scottish NHS hospitals reported 90 990 admissions for DD (in 87 314 patients) from 2000 to 2010. The annual number of admissions increased by 55.2% from 6591 in 2000 to 10,228 in 2010, an average annual increase per year of 4.5%. Most of the increase attributable to DD was due to elective day cases (3618 in 2000; 6925 in 2010) a likely consequence of a greater proportion of the population accessing colonoscopy over that time period. There was an 11% increase in inpatient admissions (2973-3303), 60% of these patients being women. Admissions in younger age groups increased proportionally in the later years of the study, and there was an association between DD admissions and greater deprivation. Despite an increase in complicated DD from 22.9% in 2000 to 27.1% in 2010 and a 16.8% increase in emergency inpatient admissions, the rate of surgery fell during the period of study. CONCLUSION: This report supports findings of other population-based studies of western countries indicating that DD is an increasing burden on health service resources, particularly in younger age groups.

Deprivation and access to treatment for colorectal cancer in Southeast Scotland 2003-2009.

AIM: Socioeconomic deprivation is associated with poorer survival from colorectal cancer. We examined the association of deprivation with access to treatment, disease stage at presentation and choice of treatment for colorectal cancer within a regional managed clinical network. METHOD: We performed a retrospective analysis of data from the Southeast Scotland Cancer Network colorectal database for the period 2003-2009. Socioeconomic status was assigned into five categories using postcode of residence and the Scottish Index of Multiple Deprivation score. Outcomes were access to consultation and treatment, stage of disease at presentation and treatment factors (type of surgery, adjuvant radiotherapy and adjuvant chemotherapy). RESULTS: Of 4960 colorectal cancer patients, 4016 patients (81%) underwent operative treatment. Deprivation was not associated with age, gender, tumour site, disease stage, delay in treatment pathway or permanent stoma rate. Primary tumour resection (P = 0.006) and chemotherapy treatment (P = 0.018) were higher in the least deprived compared with the most deprived quintile. Socioeconomic status was associated with both primary tumour resection [odds ratio for the most affluent compared with the most deprived quintiles (OR) 1.34, 95% confidence interval (CI) 1.05-1.72, P = 0.018] and chemotherapy treatment (OR 1.44, 95% CI 1.15-1.80, P = 0.001). However, when health board of treatment was added to the model, only chemotherapy treatment was independently associated with deprivation (OR 1.46, 95% CI 1.16-1.83, P = 0.001). CONCLUSION: Deprivation is not associated with treatment delay or more advanced disease stage at presentation. An apparent association between deprivation and treatment choice may be explained by other differences between patients treated in different areas.

Subspecialist emergency management of diverticulitis is associated with reduced mortality and fewer stomas.

AIM: The aim of the study was to compare outcomes for emergency management of diverticulitis before and after the creation of a regional subspecialist colorectal unit. METHOD: We retrieved data on all emergency admissions for diverticulitis from the regional surgical audit database and compared results before (January 1998 to August 2002) and after (August 2002 to December 2008) establishment of the subspecialist colorectal surgery unit in August 2002. Additional data were retrieved from electronic patient records. The primary outcome measures were mortality and rate of primary anastomosis following resection. RESULTS: There were 879 patients before and 1280 patients after subspecialization. Nonoperative management was undertaken in approximately 80% of cases. Total mortality fell from 3.3 to 1.5% (P = 0.008), attributable to reduced operative mortality (9.6 to 4.2%; P = 0.019). The primary anastomosis rate for all left colon resections increased from 50.3 to 77.9%; P < 0.0001. Stoma formation of any type fell from 46.6 to 27.7%; P < 0001). CONCLUSION: Emergency management of diverticulitis by subspecialist colorectal surgeons is associated with low overall and operative mortality whilst safely achieving high rates of primary anastomosis.

Total perineal reconstruction after abdominoperineal excision for rectal cancer: long-term results of dynamic graciloplasty with Malone appendicostomy.

AIM: This study aimed to assess long-term function after total perineal reconstruction (TPR) with dynamic graciloplasty (DG) and systematic Malone appendicostomy (MA) adjunction after abdominoperineal excision (APR) for rectal cancer. METHOD: From 1999 to 2004, TPR using DG and MA was performed in 10 patients [seven women; median age 40 (range 28-55) years] after APR for rectal cancer (cT2 in one patient, cT3 in six patients and cT4 in three patients). We prospectively recorded early and late morbidity, mortality, oncological outcome, functional results (using the modified Working Party on Anal Sphincter Replacement 'WPASR' scoring system) and quality of life (QoL; using the European Organisation for Research and Treatment of Cancer 'EORTC' QLQ-C30 and QLQ-CR38 questionnaires). RESULTS: There was no procedure-related mortality. One patient required intra-abdominal re-operation. Nine patients required local and multiple revisions [there was one coloperineal anastomosis (CPA) stenosis, five CPA mucosal prolapse, three stenosis related to graciloplasty, two MA stenosis and one MA reflux]. After a median follow up of 78 months, there was no local recurrence and six patients were alive and disease-free. Regarding the functional results, the median modified WPASR score, of 8, after a follow up of 78 months, was good. The overall QoL scores remained stable over time. CONCLUSION: In carefully selected patients who want to avoid definitive abdominal colostomy after APR for rectal cancer, reconstruction involving MA and DG after APR for low rectal cancer is followed by good long-term function and QoL.

Malone appendicostomy: an unexpected complication.

The Malone appendicostomy is a novel option for surgical management of faecal incontinence and chronic constipation, by permitting the administration of antegrade colonic enemas for colonic evacuation. We report the case of a 54-year-old female who had undergone abdomino perineal resection for low rectal cancer followed by total perineal reconstruction with perineal colostomy, dynamic double graciloplasty and Malone appendicostomy. After 7-year follow-up, functional results and quality of life scores were satisfactory. Suddenly the patient described increasing difficulty with intubation of her appendicostomy and complete reflux of the enema liquid, which radiology referred to a calcified body of 35 mm within the Malone appendicostomy causing nearly complete obstruction of the conduit. A surgical exploration was necessary to extract the fecolith allowing full recovery with return to satisfactory Malone appendicostomy function. To our knowledge, this is the first report of a fecolith causing obstruction within a Malone appendicostomy.

Small bowel perforation--an unusual complication of microdiscectomy: a case report.

A 45-year-old woman underwent microdiscectomy for sciatalgia due to prolapsed intravertebral disc between the fifth lumbar and first sacral vertebrae. Post-operatively, she developed abdominal pain and tenderness. Abdominal computerised tomography scan showed evidence of small bowel perforation. She underwent laparotomy and repair of an iatrogenic small bowel injury of the proximal ileum. Small bowel perforation is a rare complication of microdiscectomy and should be considered if abdominal symptoms develop post-operatively.

Changing trends in surgery for acute appendicitis.

BACKGROUND: Laparoscopic appendicectomy (LA) offers faster recovery times and a reduced rate of wound infection compared with open appendicectomy (OA) but may be associated with more intra-abdominal abscesses. This study examines the changing trends in management of appendicitis in a regional setting during service reorganization and compares infective complication rates for each procedure. METHODS: Data were retrieved from the Lothian Surgical Audit database on 1824 patients treated for appendicitis by OA or LA during equal 31-month periods before and after service reorganization in August 2002. Outcome measures were duration of admission, recovery time from operation to discharge and reintervention for infective complications. Analysis was by intention to treat. RESULTS: The rate of LA in Lothian increased from 29.9 to 39.4 per cent (P < 0.001) after subspecialist service reorganization. Recovery time from operation to discharge was significantly shorter after LA than OA when results were stratified with respect to sex (mean 2.5 versus 4.4 days respectively in women, P < 0.001; 2.7 and 3.1 days in men, P = 0.023), timing of surgery (2.7 versus 3.3 days before subspecialization, P = 0.007; 2.5 versus 3.6 days after subspecialization, P < 0.001) and whether appendicitis was associated with peritoneal contamination (2.2 versus 3.0 days for uncontaminated surgery, P < 0.001; 4.3 versus 5.1 days for contaminated surgery, P = 0.060). Peritoneal contamination at primary operation was the only independent risk factor that predicted reintervention for infective complications. CONCLUSION: LA is associated with a shorter hospital stay from operation to discharge than OA, with no evidence of an increased rate of intra-abdominal infective complications.

Open cholecystectomy in the laparoscopic era.

INTRODUCTION: As techniques in laparoscopic cholecystectomy have improved, surgeon experience of open cholecystectomy may be limited. This study examined the current indications for and techniques used in primary open cholecystectomy. METHODS: Some 3100 consecutive patients undergoing elective or emergency cholecystectomy over a 5-year interval were identified from a prospective surgical audit database. Demographic, diagnostic and procedural data were examined. RESULTS: There were 123 (4.0 per cent) primary and 219 (7.4 per cent) converted open cholecystectomies. Some 48.0 and 45.6 per cent of patients in the primary open cholecystectomy and converted groups respectively were men, compared with 24.0 per cent of 2758 who had a successful laparoscopic procedure. Primary open cholecystectomy was employed principally for previous upper abdominal open surgery (22.7 per cent) and emergency operation for general peritonitis (19.5 per cent). The fundus-first approach was employed in 53.7 per cent of primary open procedures and 53.0 per cent of conversions, with subtotal excision in 4.9 and 13.2 per cent respectively. CONCLUSION: Primary open cholecystectomy remains a common procedure in the treatment of gallbladder disease despite the success of laparoscopic cholecystectomy. Successful outcome in difficult cases requires familiarity with specific techniques, exposure to which may be limited in current training programmes.

Totally extraperitoneal laparoscopic hernia repair in patients with previous lower abdominal surgery.

INTRODUCTION: Patients with lower abdominal scars are generally excluded from laparoscopic hernia repair due to the perceived technical difficulty and risk of visceral injury. This study examines the outcome of a series of patients who underwent totally extraperitoneal (TEP) inguinal hernia repair despite previous lower abdominal surgery. METHODS: Retrospective review of 47 consecutive patients who underwent TEP inguinal hernia repair in the presence of lower abdominal scars between 1993 and 2002. RESULTS: Thirty-five unilateral and 12 bilateral TEP hernia repairs were performed in the presence of 20 appendicectomy, 10 lower midline, 18 suprapubic and 5 paramedian incisions. Two cases were converted to open repair. There were no major complications and no early or late recurrences. Median operating time was 67.5 min and 83% of patients were managed as day cases. CONCLUSIONS: Totally extraperitoneal laparoscopic hernia repair can be carried out safely in the presence of scars from previous lower abdominal surgery.

Perceiving affect from arm movement.

We examined the visual perception of affect from point-light displays of arm movements. Two actors were instructed to perform drinking and knocking movements with ten different affects while the three-dimensional positions of their arms were recorded. Point-light animations of these natural movements and phase-scrambled, upside-down versions of the same knocking movements were shown to participants who were asked to categorize the affect of the display. In both cases the resulting confusion matrices were analyzed using multidimensional scaling. For the natural movements the resulting two-dimensional psychological space was similar to a circumplex with the first dimension appearing as activation and the second dimension as pleasantness. For the scrambled displays the first dimension was similar in structure to that obtained for the natural movements but the second dimension was not. With both natural and scrambled movements Dimension 1 of the psychological space was highly correlated to the kinematics of the movement. These results suggest that the corresponding activation of perceived affect is a formless cue that relates directly to the movement kinematics while the pleasantness of the movement appears to be carried in the phase relations between the different limb segments.

Mobile phone technology and hospitalized patients: a cross-sectional surveillance study of bacterial colonization, and patient opinions and behaviours.

Healthcare workers' mobile phones provide a reservoir of bacteria known to cause nosocomial infections. UK National Health Service restrictions on the utilization of mobile phones within hospitals have been relaxed; however, utilization of these devices by inpatients and the risk of cross-contamination are currently unknown. Here, we examine demographics and characteristics of mobile phone utilization by inpatients and phone surface microbial contamination. One hundred and two out of 145 (70.3%) inpatients who completed a questionnaire detailing their opinions and utilization of mobile phones, also provided their mobile phones for bacteriological analysis and comparative bacteriological swabs from their nasal cavities; 92.4% of patients support utilization of mobile phones by inpatients; indeed, 24.5% of patients stated that mobile phones were vital to their inpatient stay. Patients in younger age categories were more likely to possess a mobile phone both inside and outside hospital (p <0.01) but there was no gender association. Eighty-six out of 102 (84.3%) patients' mobile phone swabs were positive for microbial contamination. Twelve (11.8%) phones grew bacteria known to cause nosocomial infection. Seven (6.9%) phones and 32 (31.4%) nasal swabs demonstrated Staphylococcus aureus contamination. MSSA/MRSA contamination of phones was associated with concomitant nasal colonization. Patient utilization of mobile phones in the clinical setting is popular and common; however, we recommend that patients are educated by clear guidelines and advice on inpatient mobile phone etiquette, power charging safety, regular cleaning of phones and hand hygiene, and advised not to share phones or related equipment with other inpatients in order to prevent transmission of bacteria.

Color Doppler sonography of small bowel wall changes in 21 consecutive cases of acute mesenteric ischemia.

AIM OF THE STUDY: To describe the small bowel wall changes observed with color Doppler sonography in acute mesenteric ischemia with comparison with its outcome. MATERIAL AND METHODS: We reviewed the sonographic findings of 21 patients with a final diagnosis of acute mesenteric ischemia (12 acute arterial forms and 9 acute venous forms). These examinations included identification of non peristaltic thin-walled fluid-filled intestinal loops (with or without pneumatosis), thickened intestinal wall (> 3 mm) (noted as stratified or not), and preserved or absent mural flow assessed with color Doppler. Sonographic findings were compared with the surgical data (n = 16) or with the clinical outcome (n = 5). RESULTS: In acute arterial ischemia, non-peristaltic thin-walled intestinal loops were detected with sonography in five cases, with visualization of pneumatosis in one. Bowel infarction was diagnosed in four of these five patients including one patient with pneumatosis. Thickened bowel loops were sonographically detected in four cases, of which 3 required resection. Conservative therapy was performed in the remaining case having preserved wall stratification and mural flow with color Doppler. In acute venous ischemia, thickened bowel loops were detected with sonography in six cases. Conservative therapy was performed in three cases for whom preserved mural flow was noted. Stratification was present in two of these three cases. CONCLUSION: In acute arterial ischemia, intestinal resection is frequently required when non-peristaltic, thin-walled, fluid-filled loops are detected with sonography. In arterial and venous ischemia, absence of wall stratification and mural flow are frequently associated with ischemia requiring surgery.

Improved management of acute gallstone disease after regional surgical subspecialization.

PURPOSE: Acute gallstone disease is a common indication for emergency hospital admission, and evidence now strongly supports early laparoscopic cholecystectomy as the treatment of choice. Recent data from the UK suggest that this is achieved in a minority of cases with a high proportion of patients managed by deferred elective surgery or emergency open cholecystectomy. We present results of a policy of definitive treatment during index admission after subspecialist reorganization of a regional emergency surgical service. METHODS: Data for all emergency gallstone admissions were retrieved from a prospectively collected regional surgical audit database and results were compared from 31 month periods before and after subspecialist service reorganization in August 2002. RESULTS: A total of 2442 patients were analyzed. Before subspecialization, 458 of 733 patients (62.4%) underwent cholecystectomy during index admission; after subspecialization, cholecystectomy during index admission for biliary colic/acute cholecystitis was achieved in 666 of 817 (81.5%) patients (90.2% laparoscopic, 6.5% conversion rate, and 3.3% primary open cholecystectomy) with a reduction in hospital stay from median 5 to 4 days. The rate of deferred surgery decreased from 37.5% to 18.4%. Early surgery reduced total hospital admission by more than 1 day per patient compared with deferred surgery. CONCLUSIONS: Early laparoscopic cholecystectomy during emergency admission is cost-effective and should be regarded as the standard of care. However, it requires appropriately trained surgeons and availability of a dedicated emergency room, which at present are not consistently provided in all regions of the UK.
