RESUMO

Introduction Emergency general surgery services in England are undergoing rapid structural change with the aim of improving care. In our centre, the key issues identified were high numbers of admissions, inappropriate referrals, prolonged waiting times, delayed senior input and poor patient satisfaction. A new model was launched in January 2015 to address these issues: the surgical triage unit (STU). This study assesses the success of the new service. Methods All emergency general surgical admissions during a five-month period before introduction of the STU were compared with those of a comparable five-month period after its introduction. Process, clinical and patient experience outcomes were assessed to identify improvement. Results Attendance fell from 3,304 patients in the 2014 cohort to 2,830 in the 2015 cohort. During the 2015 study period, 279 more patients were discharged on the same day. Resource requirement fell by 2,635 bed days (23%). The number of true surgical emergencies remained consistent. Rates for reattendance (7.8% for 2014 vs 8.1% for 2015) and readmission (5.7% for 2014 vs 5.7% for 2015) showed no significant difference. Patient experience data demonstrated a significant improvement in both net promoter score (64.1 vs 82.2) and number of complaints (34 vs 5). Clinical outcomes for low risk procedures remained similar. Emergency laparotomy in-hospital mortality fell (11.4% vs 10.3%) despite preoperative risk stratification suggesting a risk burden that was significantly higher than the national average. Conclusions This novel model of emergency general surgery provision has improved clinical efficiency, patient satisfaction and outcomes. We encourage other units to consider similar programmes of service improvement.

RESUMO

The optimal management of resectable oesophageal adenocarcinoma is controversial, with many centres using neoadjuvant chemotherapy following the Medical Research Council (MRC) oesophageal working group (OE02) trial and the MRC Adjuvant Gastric Infusional Chemotherapy (MAGIC) trial. The more intensive MAGIC regimen is used primarily in gastric cancer but some also use it for oesophageal cancer. A database of cancer resections (2001-2013) provided information on survival of patients following either OE02 or MAGIC-type treatment. The data were compared using Kaplan-Meier analysis. Straight-to-surgery patients were also reviewed and divided into an 'early' cohort (2001-2006, OE02 era) and a 'late' cohort (2006-2013, MAGIC era) to estimate changes in survival over time. Subgroup analysis was performed for responders (tumour regression grade [TRG] 1-3) versus non-responders (TRG 4 and 5) and for anatomical site (gastro-oesophageal junction [GOJ] vs oesophagus). An OE02 regimen was used for 97 patients and 275 received a MAGIC regimen. Those in the MAGIC group were of a similar age to those undergoing OE02 chemotherapy but the proportion of oesophageal cancers was higher among MAGIC patients than among those receiving OE02 treatment. MAGIC patients had a significantly lower stage following chemotherapy than OE02 patients and a higher median overall survival although TRG was similar. On subgroup analysis, this survival benefit was maintained for GOJ and oesophageal cancer patients as well as non-responders. Analysis of responders showed no difference between regimens. 'Late' group straight-to-surgery patients were significantly older than those in the 'early' group. Survival, however, was not significantly different for these two cohorts. Although the original MAGIC trial comprised few oesophageal cancer cases, our patients had better survival with MAGIC than with OE02 chemotherapy in all anatomical subgroups, even though there was no significant change in operative survival over the time period in which these patients were treated. The use of the MAGIC regimen should therefore be encouraged in cases of operable oesophagogastric adenocarcinoma.

RESUMO

BACKGROUND: Patients with potentially curative oesophago-gastric cancer typically undergo neo-adjuvant chemotherapy prior to surgery. The majority of anti-cancer drugs have a narrow therapeutic index. The aim of this study was to determine if features of body composition, assessed using computed tomography (CT) scans, may be predictive of dose-limiting toxicity (DLT) in patients undergoing neo-adjuvant chemotherapy for oesophago-gastric cancer. The influence of sarcopenia and DLT on overall survival was also evaluated. METHODS: 89 Patients having potentially curative oesophago-gastric cancer surgery were studied. Patients studied had histologically confirmed oesophago-gastric cancer with no evidence of distant metastasis on pre-operative staging. CT scan was performed in all cases at diagnosis. DLT was defined as toxicity leading to postponement of treatment, a drug dose reduction or definitive interruption of drug administration. RESULTS: DLT occurred in 37 out of 89 patients (41.6%) undergoing chemotherapy. Sarcopenia (odds ratio, 2.95; 95% confidence interval, 1.23-7.09; p = 0.015) was associated with DLT on multivariate analysis. Median overall survival for patients who were sarcopenic was 569 days (IQ range: 357-1230 days) vs. 1013 days (IQ range: 496-1318 days) for patients who were not sarcopenic (p = 0.04). There was no significant difference in overall survival in patients who experienced DLT compared with those that did not (p = 0.665). CONCLUSIONS: Sarcopenia is a significant predictor of DLT in oesophago-gastric cancer patients undergoing neo-adjuvant chemotherapy. These results raise the potential for use of assessment of skeletal muscle mass using CT scans to predict toxicity and individualize chemotherapy dosing.

RESUMO

INTRODUCTION: The high mortality and morbidity associated with resection for oesophagogastric malignancy has resulted in a conservative approach to the postoperative management of this patient group. In August 2009 we introduced an enhanced recovery after surgery (ERAS) pathway tailored to patients undergoing resection for oesophagogastric malignancy. We aimed to assess the impact of this change in practice on standard clinical outcomes. METHODS: Two cohorts were studied of patients undergoing resection for oesophagogastric malignancy before (August 2008 - July 2009) and after (August 2009 - July 2010) the implementation of the ERAS pathway. Data were collected on demographics, interventions, length of stay, morbidity and in-hospital mortality. RESULTS: There were 53 and 55 oesophagogastric resections undertaken respectively for malignant disease in each of the study periods. The median length of stay for both gastric and oesophageal resection decreased from 15 to 11 days (Mann-Whitney U, p<0.001) following implementation of the ERAS pathway. There was no significant increase in morbidity (gastric resection 23.1% vs 5.3% and oesophageal resection 25.9% vs 16.7%) or mortality (gastric resection no deaths and oesophageal resection 1.8% vs 3.6%) associated with the changes. There was a significant decrease in the number of oral contrast studies used following oesophageal resection, with a reduction from 21 (77.8%) in 2008-2009 to 6 (16.7%) in 2009-2010 (chi-squared test, p<0.0001). CONCLUSIONS: The introduction of an enhanced recovery programme following oesophagogastric surgery resulted in a significant decrease in length of median patient stay in hospital without a significant increase in associated morbidity and mortality.

RESUMO

OBJECTIVES: To report our experience with gastrointestinal stromal tumours (GISTs). METHODS: Retrospective data were collected from January 1987 to December 2003. Clinical and histological data were analysed to identify recurrence patterns and factors predicting survival. The tumours were studied with respect to size, number of mitosis and cell type. RESULTS: One hundred and eighty-five patients were identified with GIST with the age range of 18-93 years (mean 64.4 years) with a mean follow up of 6.7 years. Eighty out of 185 patients were in the low group, 38/185 in intermediate risk and 67/185 were in the high risk group. Eighty-three percent of the patients underwent surgical resection. Ten percent of the patients in the intermediate group and 25% of the patients in high risk group developed recurrence. Mortality was 5% and 37% in intermediate and high risk groups, respectively. There was no tumour related mortality or recurrence in the low risk group. CONCLUSIONS: It is important to identify the patients in low and high risk groups. Patients in intermediate and high risk groups require complete resection (R0) and follow up with CT scans.

RESUMO

BACKGROUND: Breast cancer metastasis to the gastrointestinal tract (GIT) is rare. When it does occur, the upper GIT is more frequently involved, and lobular infiltrating carcinoma apparently has a greater apparent predilection for the GIT than the ductal type does. This study reviewed the clinicopathological features of esophagogastric secondary tumors from breast cancer. PATIENTS AND METHODS: Patients with breast cancer metastases to the upper GIT referred to us for treatment of either esophageal or gastric cancers between November 1997 and November 2004 were identified from our database. The medical records of these patients were then reviewed for clinicopathological data and outcome. RESULTS: Nine patients with mean age of 71 (range: 57-90) years had median time of 6.5 (2.8-32.8) years between primary breast cancer diagnosis and upper GI metastasis. The sites of metastatic lesions included the lower esophagus (2 patients), gastroesophageal junction (1 patient), gastric body (3 patients), and pylorus (3 patients). Histological typing indicated 7 cases of the lobular form and 2 cases of ductal carcinoma. All but one biopsy specimen were estrogen receptor and CK7 positive. Treatment included hormonal therapy and stent in 3 patients, hormonal therapy alone in 1 patient, chemotherapy alone in 1 patient, chemotherapy and gastrojejunostomy in 1 patient, dilatation and stent in 1 patient, and palliative care only in 2 patients. The median survival following treatment of these metastases was 20 (range: 2.1-96.6) months. CONCLUSIONS: The onset of nonspecific GIT symptoms in patients with a history of breast carcinoma should prompt the clinician to rule out the possibility of upper GIT metastasis even many years after the original breast cancer. The use of systemic therapy for breast cancer may result in longer survival.

RESUMO

AIMS: Selection of patients for treatment of oesophagogastric cancers rests on accurate staging. Laparoscopy has become a safe and effective staging tool in upper gastrointestinal cancers because of its ability to detect small peritoneal and liver metastases missed by imaging techniques. The aim of this study was to evaluate the role of staging laparoscopy (SL) in determining resectability of oesophagogastric cancers. METHODS: A review of 511 patients with oesophagogastric cancers referred to our centre during a 7-year period was performed. Four hundred and sixteen of them assessed to have resectable tumours after preoperative staging with CT and/or ultrasound underwent SL. The main outcome measure was the number of patients in whom laparoscopy changed treatment decision. RESULTS: Staging laparoscopy changed treatment decision in 84 cases (20.2%): locally advanced disease in 17, extensive lymph node disease in four and distant metastases (liver and peritoneum) in 63 cases. The sensitivity of laparoscopy for resectability was 88%. Eighty-one percent of patients who had combined CT scan and EUS were resectable at surgery compared with 65% of those who had CT scan alone (statistically significant with P-value<0.05). Of those patients deemed resectable by SL 8.1% were found to be unresectable at laparotomy, 16 with locally advanced disease and 11 with metastases. CONCLUSION: Staging laparoscopy avoided unnecessary laparotomy in 20.2% of our patients and was most useful in adenocarcinoma, distal oesophageal, GOJ and gastric cancers and probably not necessary in lesions of the upper two-third of the oesophagus.

RESUMO

To survey patients/carers' use of the Internet and other sources for health information, to determine how useful health information over the Internet was to patients/carers and to assess the potential use of validated health information on the Internet by our patients. A multidisciplinary questionnaire survey of the use of the Internet for health information was performed. The study population consisted of patients and accompanying adults 18 years and older who attended outpatient clinics at Nottingham City Hospital for a period of two weeks in July 2005. The questionnaire captured information on demographics, frequency of use of the Internet, sources of health information, satisfaction rating of health information obtained on the Internet and their interest in using trustworthy health information Internet site if made available. Of the 800 questionnaires sent out, 663 responded (83%). Sixty three percent of patients had access to the Internet. 42% of the participants had used the Internet to access health information prior to this survey. 7.5% of the participants who have no access to the Internet, have had someone else look up health information on the Internet on their behalf. 95% of the respondents who had used the Internet for health information rated such information between average to excellent. 82% of those with Internet access and 21% of those with no Internet access would be interested in using trustworthy health information on the internet. Nearly half of our population of secondary care patients have used the internet to access health information and most are interested in using validated health information. Delivery of validated health information via the internet should be a priority for health care providers.

RESUMO

BACKGROUND: Endoscopic screening for Barrett's oesophagus is being offered without evidence of efficacy Barrett's oesophagus is not an ideal candidate for a screening programme, as the natural history is unclear, uncertainties surround the indication for intervention and the treatment is associated with high morbidity and mortality rates. METHODS: To determine the practices that clinicians employ in the management of Barrett's oesophagus in the UK, postal questionnaires were sent in May 1997 to 297 randomly selected members of the British Society of Gastroenterology asking for details of their current practice. RESULTS: Of 152 respondents, 106 (70 per cent) performed surveillance for Barrett's oesophagus; 46 (30 per cent) did not carry out screening. There was no difference in the practices carried out by physicians or surgeons, teaching or acute general hospital clinicians, or those with an upper gastrointestinal interest. There was a wide disparity in screening interval: just over half (52 per cent) screen at yearly intervals. Only nine (8 per cent) took four quadrant biopsies per 2 cm of Barrett's oesophagus. Nearly half (49 per cent) manage mild dysplasia by increasing the frequency of endoscopy; only seven (7 per cent) prescribed patients a proton pump inhibiting agent. Faced with severe dysplasia, 33 (31 per cent) offered surgery immediately; 22 (21 per cent) simply followed the patient by endoscopy. Those not choosing to perform screening most frequently cited lack of evidence of efficacy as the reason behind their decision. CONCLUSION: There is wide variation in surveillance practices for Barrett's oesophagus. Some methods are ineffectual. The recommendations made by the Barrett's Oesophagus Working Party in 1991 are not followed, possibly because they are not practical. New workable guidelines based on available evidence and a consensus of expert opinion should be established; this was suggested by 38 per cent of respondents who performed screening.

RESUMO

The effects of the intravenous bolus administration of famotidine versus the administration of Mylanta II liquid every 2 hours on the pH of the gastric antrum, body, and fundus for 24 hours were compared in 10 critically ill patients admitted to the intensive care unit with isolated cranial trauma. Patients received 30 mL of Mylanta II every 2 hours via nasogastric tube for 24 hours, followed by administration of 20 mg of intravenous bolus famotidine every 12 hours for the subsequent 24-hour period. pH of the gastric antrum, body, and fundus was monitored continuously using a three antimony pH electrode/nasogastric tube assembly. Gastric pH data were analyzed for the percentage of time pH was less than 4 and median pH for the antrum, body, and fundus for each 24-hour period. The percentage of time pH was less than 4 was significantly less in the antrum and body of the stomach during famotidine therapy (8.9% +/- 3.6% and 24.9% +/- 6.9%, respectively) compared with Mylanta II (39.1% +/- 6.7% and 57.6% +/- 8.5%, respectively, both p < 0.005), but was not significantly different in the fundus (famotidine: 25.3% +/- 7.8%; Mylanta II: 28.3% +/- 6.5%). Median gastric pH for 24 hours was significantly greater in the antrum and body of the stomach during famotidine therapy (7.8 +/- 0.2 and 6.8 +/- 0.6, respectively) compared with Mylanta II (4.5 +/- 0.6 and 3.7 +/- 0.9, respectively, p < 0.005 and p < 0.01, respectively), but was not significantly different in the fundus (famotidine: 5.9 +/- 0.8; Mylanta II: 5.4 +/- 0.7). The data indicate that an intravenous bolus of famotidine every 12 hours is more effective than Mylanta II liquid every 2 hours administered via a nasogastric tube in maintaining gastric pH above 4 in critically ill patients. Famotidine produces a uniform increase in gastric pH throughout the stomach, whereas Mylanta II controls only proximal gastric pH, probably related to fundic pooling of antacid in the supine position.

RESUMO

Fasting and postprandial plasma levels of the gut hormones gastrin, cholecystokinin (CCK), secretin, glucose-dependent insulinotropic polypeptide, motilin, neurotensin, peptide YY (PYY), enteroglucagon, glucagon, insulin, and pancreatic polypeptide were measured in 11 patients with alkaline gastritis associated with excessive duodenogastric reflux not related to previous gastric surgery (primary DGR), 12 primary DGR patients after pancreatico-biliary diversion ("duodenal switch" procedure), and in 10 age-matched healthy controls. Gastric emptying of a semisolid oatmeal was also measured in patients with primary DGR and in patients after bile diversion. Fasting plasma levels of the distal gut hormone neurotensin and the pancreatic islet hormone insulin were significantly greater in patients with primary DGR compared with controls. Neurotensin levels were normal in patients studied after bile diversion. Postprandial plasma levels, incremental integrated and total integrated responses for CCK, secretin, insulin, neurotensin, PYY, and enteroglucagon, were significantly greater in patients with primary DGR compared with controls. The majority of these responses normalized after bile diversion; however, the postprandial response for insulin and enteroglucagon remained elevated. Patients with primary DGR had a rapid early postprandial phase of gastric emptying of solids, which showed a significant correlation with plasma neurotensin levels. Bile diversion produced a significant delay in this lag-phase of gastric emptying. These abnormalities in gut regulatory hormones appear to be adaptive changes to rapid early postprandial gastric emptying, probably related to antropyloric dysmotility, which has been implicated in the pathogenesis of this condition. Measurement of these gastrointestinal hormones may become useful in the diagnosis of primary DGR.

RESUMO

The duodenal switch operation preserves the pylorus and the proximal 3 to 7 cm of duodenum in continuity with the stomach while diverting pancreaticobiliary secretions. We compared it with the Roux-en-Y without vagotomy or antrectomy in 12 dogs with innervated gastric pouches. Acid secretion was inhibited between tests using ranitidine in the Roux-en-Y group only, but two of the six dogs still developed stomal ulcers and the remainder showed stomal hyperemia. This may be due to a significant increase in gastric acid output after Roux-en-Y, but gastric emptying and plasma gastrin, cholecystokinin, secretin, gastric inhibitory polypeptide, peptide YY, and neurotensin were similar after both procedures. In 12 patients and a further 6 dogs, the duodenal switch caused no significant change in the intragastric pH environment as assessed by intragastric pH monitoring. The duodenal switch is a suitable procedure for pancreaticobiliary diversion.

RESUMO

Technical problems of retraction and hemorrhage during laparoscopic removal of a porcelain gallbladder are described. Although laparoscopic cholecystectomy was successful, a blood transfusion was required. We believe that porcelain gallbladder is a relative contraindication to laparoscopic cholecystectomy. The merits of plain radiography, computed tomography, and ultrasound in making the diagnosis are also discussed.

RESUMO

The benefits and risks of laparoscopic incidental appendectomy are discussed. We believe a case for laparoscopic incidental appendectomy can be made for patients undergoing diagnostic laparoscopy for lower abdominal pain in whom either no cause is found, or in whom a cause other than appendicitis is discovered. No benefit from incidental appendectomy can be shown for patients undergoing laparoscopy for other disorders.
