RESUMO
Dysphagia is a highly prevalent symptom in Amyotrophic Lateral Sclerosis (ALS), and the implantation of a percutaneous endoscopic gastrostomy (PEG) is a very frequent event. The aim of this study was to evaluate the influence of PEG implantation on survival and complications in ALS. An interhospital registry of patients with ALS of six hospitals in the Castilla-León region (Spain) was created between January 2015 and December 2017. The data were compared for those in whom a PEG was implanted and those who it was not. A total of 93 patients were analyzed. The mean age of the patients was 64.63 (17.67) years. A total of 38 patients (38.8%) had a PEG implantation. An improvement in the anthropometric parameters was observed among patients who had a PEG from the beginning of nutritional follow-up compared to those who did not, both in BMI (kg/m2) (PEG: 0 months, 22.06; 6 months, 23.04; p < 0.01; NoPEG: 0 months, 24.59-23.87; p > 0.05). Among the deceased patients, 38 (40.4%) those who had an implanted PEG (20 patients (52.6%) had a longer survival time (PEG: 23 (15-35.5) months; NoPEG 11 (4.75-18.5) months; p = 0.01). A PEG showed a survival benefit among ALS patients. Early implantation of a PEG produced a reduction in admissions associated with complications derived from it.

Severe acute pancreatitis complicated by infection is associated with high mortality. Invasive treatment is indicated in the presence of infected (suspected) pancreatic and/or peripancreatic necrosis (IPN) in the absence of response to intensive medical support. Step-up approach (SUA) has been demonstrated to lower complication rate compared to upfront open surgery. However, this approach has not been associated with lower mortality, and no factors have been studied that could help to identify the high risk patients. In this study, we aimed to analyse those factors associated with mortality following the invasive treatment of IPN, focusing on the role of surgical necrosectomy. A retrospective and observational study based on a multicentre prospective database was conducted. The database was coordinated by the Hospital General Universitario de Alicante, Spain and the Spanish Association of Pancreatology. Demographics, clinical data, and laboratory and imaging findings were collected. Atlanta 2012 criteria were considered to classify acute necrotizing pancreatitis and for the definition of IPN. Step-up approach was used in all centres with the intention of avoiding surgery whenever possible. Surgical necrosectomy was performed by open approach. From January 2013 to October 2014, a total of 1655 patients with the diagnosis of acute pancreatitis were included in our database. 1081 were recruited for the final analysis. Out of them, 205 (19%) were classified into acute necrotizing pancreatitis. 77 (8.3%) patients underwent invasive treatment of INP and were included in our study. Overall mortality was 29.9%. Upfront endoscopic or percutaneous drainage was performed in 60 (77.9%) patients and mortality was 26.6%. Out of 60, 22 (36.6%) patients subsequently received rescue surgery; mortality in rescue surgery group was 18.3%. Upfront surgery was carried out in 17 (22.1%) patients; mortality in this group was 41%. At univariate analysis, surgical necrosectomy, extrapancreatic infection, immunosuppression and de-novo haemodialysis were associated with mortality. At multivariate analysis, only surgical necrosectomy was significantly associated with mortality (p = 0.002 OR 3.89). Surgical approach for IPN is associated with high mortality rate. However, these data should be interpreted with caution, since we are not able to assess whether this occurs due to the need of surgery as the only resort when the other approaches are not feasible or fail.

Surgical approach (SA) is the standard treatment for infected necrotizing pancreatitis (INP) and endoscopic transgastric approach (ETA) is a promising alternative treatment. This systematic review and meta-analysis aimed to compare the effectiveness and safety of ETA versus SA in INP. Several databases were systematically searched for eligible studies that compared ETA with SA for INP. Predefined criteria were used for study selection. Three reviewers independently assessed the risk of bias. Primary outcomes included clinical resolution rate, short-term mortality, major complications, and hospital stay. Study-specific effect sizes and their 95% confidence interval (CI) were combined to calculate the pooled value using fixed-effects or random-effects model. Six studies were included with 295 patients. Major complication rate [odds ratio (OR), 0.13; 95% CI, 0.06-0.29], new-onset organ failure rate (OR, 0.26; 95% CI, 0.12-0.54), postoperative pancreatic fistula rate (OR, 0.09; 95% CI, 0.03-0.28), and incisional hernia rate (OR, 0.10; 95% CI, 0.01-0.85) were lower in the ETA group. There was a shorter hospital stay (mean difference, -17.72; 95% CI, -21.30 to -14.13) in the ETA group. No differences were found in clinical resolution, short-term mortality, postoperative bleeding, perforation of visceral organ, and endocrine or exocrine insufficiency. Compared with SA, ETA showed comparable effectiveness and safety for the treatment of INP based on current evidence.

AIMS: Neuroendocrine gastroenteropancreatic tumors are infrequently found neoplasms. Our objective was to analyze the survival rates for all sites that they occur in by studying different variables. MATERIALS AND METHODS: A retrospective study was carried out using records for a 7-year period from January 1, 2008 to December 31, 2014 on neuroendocrine gastroenteropancreatic tumors patients diagnosed at the Pontevedra-Salnés Hospital Complex. The variables used were as follows: age at diagnosis, tumor size, presence or absence of metastases at diagnosis, cell proliferation index, Ki-67 of each tumor, treatments received, postdiagnosis survival time, existence or not of tumor progression, and time from diagnosis to progression and from diagnosis to mortality. In relation to treatments, the information recorded was whether the treatment was endoscopic, surgical, or pharmacological. RESULTS: Ninety-three neuroendocrine tumors made up a ratio of 4.42 cases per 100,000 inhabitants per annum. The median patient follow-up time was 44 months. The overall 5-year survival rate for patients who were followed up for a minimum of 60 months (49 patients) was 65.3%. The progression-free survival was 75.6% for 41 patients who were followed up for a minimum of 60 months. The survival rate for patients receiving endoscopic treatment was 100%, as there was no patient mortality recorded for those treated by endoscopic resection during the follow-up period. CONCLUSION: Pancreatic neuroendocrine tumors may be managed conservatively in elderly patients by either monitoring them with imaging studies or treating them with somatostatin analogs. In the case of digestive tract tumors (stomach, duodenum, and rectum) that meet the criteria for endoscopic resection, this is a reliable and safe technique in the long term.

BACKGROUND: The optimal clinical management of patients following ingestion of potentially caustic lesions is still undetermined. In particular, the indication for early upper GI endoscopy in this context remains unclear. PURPOSE: To draft recommendations regarding the use of early upper GI endoscopy following hospital admissions of patients after ingestion of potentially caustic agents. METHODS: For this purpose, a retrospective cohort study of patients treated for ingestion of potentially caustic substances during a 13 year-period at the university hospital of Berne was performed. RESULTS: In total, 61 patients with acute ingestion of potentially caustic substances were identified. Overall mortality was 5â%. 11/61 patients had to be admitted to the intensive care unit. Most ingestions were performed in suicidal intention (62â%). In 53â% of these patients, a combined ingestion of several substances occurred. In 33â% of patients, an early upper GI endoscopy was performed within 24 hours after ingestion. The degree of burn depended upon the hazard potential of the respective substance. In patients with ingestion of low risk substances, upper GI endoscopy was only performed when additional risk factors were present. CONCLUSION: Based upon the results of the present study, ingestion of potentially caustic agents requires an individualized strategy whether or not to perform early endoscopy.

AIM: Retrospective analysis of the results of stenting versus surgical palliation in patients with malignant gastrointestinal stenosis. MATERIAL AND METHODS: 85 patients underwent endoscopic stenting (41) or surgical intervention (44). Level of stenosis: gastric outlet (23/38), multi-level gastric obstruction (2/3), duodenum or jejunum (12/3), gastrojejunoanastomosis (3/0) and gastroduodenoanastomosis (1/0). 49 self-expanding metal stents were implanted in 41 patients. 41 gastroenteroanastomoses and 3 jejunostomas were performed in surgical group. RESULTS: Stents were successfully inserted in all patients. Early complications were observed in 3 (7.3%) patients after stenting and in 9 (20.5%) after surgical palliation, p = 0.0755. Postoperative lethality was 2,4% (1 patient) after stenting and 31.8% (14 patients) after surgery, p = 0.0003. Mean hospital stay was 15 days in stenting group and 23 days in surgical group, p < 0.001. There was no statistically significant difference in long-term results, neither in late complications (p = 0.3691), nor in survival (p =0.3697). CONCLUSION: Endoscopic placement of self-expanding stents is an effective method of restoration of oral intake in patients with malignant gastrointestinal obstruction. Stenting is associated with equal rates of early and late complications, lower mortality and decreased in-hospital stay as compared with surgery, and therefore may be recommended as a final palliation in inoperable patients.

Ampullary neoplasms, although rare, present distinctive clinical and pathological features from other neoplastic lesions of the periampullary region. No specific guidelines about their management are available, and they are often assimilated either to biliary tract or to pancreatic carcinomas. Due to their location, they tend to become symptomatic at an earlier stage compared to pancreatic malignancies. This behaviour results in a higher resectability rate at diagnosis. From a pathological point of view they arise in a zone of transition between two different epithelia, and, according to their origin, may be divided into pancreatobiliary or intestinal type. This classification has a substantial impact on prognosis. In most cases, pancreaticoduodenectomy represents the treatment of choice when there is an overt or highly suspicious malignant behaviour. The rate of potentially curative resection is as high as 90% and in high-volume centres an acceptable rate of complications is reported. In selected situations less invasive approaches, such as ampullectomy, have been advocated, although there are some concerns mainly because of a higher recurrence rate associated with limited resections for invasive carcinomas. Importantly, these methods have the drawback of not including an appropriate lymphadenectomy, while nodal involvement has been shown to be frequently present also in apparently low-risk carcinomas. Endoscopic ampullectomy is now the procedure of choice in case of low up to high-grade dysplasia providing a proper assessment of the T status by endoscopic ultrasound. In the present paper the evidence currently available is reviewed, with the aim of offering an updated framework for diagnosis and management of this specific type of disease.

BACKGROUND: Emergency upper gastrointestinal bleeding is a common condition with high mortality. Most patients undergo oesophagogastroduodenoscopy (OGD), but no universally agreed approach exists to the type of airway management required during the procedure. We aimed to compare anaesthesia care with tracheal intubation (TI group) and without airway instrumentation (monitored anaesthesia care, MAC group) during emergency OGD. METHODS: This was a prospective, nationwide, population-based cohort study during 2006-13. Emergency OGDs performed under anaesthesia care were included. End points were 90 day mortality (primary) and length of stay in hospital (secondary). Associations between exposure and outcomes were assessed in logistic and linear regression models, adjusted for the following potential confounders: shock at admission, level of anaesthetic expertise present, ASA score, Charlson comorbidity index score, BMI, age, sex, alcohol use, referral origin (home or in-hospital), Forrest classification, ulcer localization, and postoperative care. RESULTS: The study group comprised 3580 patients under anaesthesia care: 2101 (59%) for the TI group and 1479 (41%) for the MAC group. During the first 90 days after OGD, 18.9% in the TI group and 18.4% in the MAC group died, crude odds ratio=1.03 [95% confidence interval (CI)=0.87-1.23, P=0.701], adjusted odds ratio=0.95 (95% CI=0.79-1.15, P=0.590). Patients in the TI group stayed slightly longer in hospital [mean 8.16 (95% CI=7.63-8.60) vs 7.63 days (95%=CI 6.92-8.33), P=0.108 in adjusted analysis]. CONCLUSIONS: In this large population-based cohort study, anaesthesia care with TI was not different from anaesthesia care without airway instrumentation in patients undergoing emergency OGD in terms of 90 day mortality and length of hospital stay.

In 1886, Senn stated that removing necrotic pancreatic and peripancreatic tissue would benefit patients with severe acute pancreatitis. Since then, necrosectomy has been a mainstay of surgical procedures for infected necrotizing pancreatitis (NP). No published report has successfully questioned the role of necrosectomy. Recently, however, increasing evidence shows good outcomes when treating walled-off necrotizing pancreatitis without a necrosectomy. The literature concerning NP published primarily after 2000 was reviewed; it demonstrates the feasibility of a paradigm shift. The majority (75%) of minimally invasive necrosectomies show higher completion rates: between 80% and 100%. Transluminal endoscopic necrosectomy has shown remarkable results when combined with percutaneous drainage or a metallic stent. Related morbidities range from 40% to 92%. Single-digit mortality rates have been achieved with transluminal endoscopic necrosectomy, but not with video-assisted retroperitoneal necrosectomy series. Drainage procedures without necrosectomy have evolved from percutaneous drainage to transluminal endoscopic drainage with or without percutaneous endoscopic gastrostomy access for laparoscopic instruments. Most series have reached higher success rates of 79%-93%, and even 100%, using transcystic multiple drainage methods. It is becoming evident that transluminal endoscopic drainage treatment of walled-off NP without a necrosectomy is feasible. With further refinement of the drainage procedures, a paradigm shift from necrosectomy to drainage is inevitable.

Abstract Gallbladder polyps are most commonly treated with cholecystectomy, which is associated with various complications. For benign disease, preserving the gallbladder is preferable. Since 1994, we have been exploring percutaneous polypectomy and have recently developed an improved new technique. This study reports a new endoscopic-laparoscopic (Endolap) technique for the removal of polyps and the preservation of the gallbladder. Nine Chinese mini-pigs were used to observe mucosal regeneration. Microwaves of 50-70 mA for 9 seconds were safe, and the gallbladder mucosa of pigs recovered to nearly normal 2 weeks later. In the clinical cases, 60 patients with gallbladder polyps were studied. With the patient under general anesthesia, each polyp stem was coagulated, and then the polyp was removed. All procedures were successful at between 60 and 135 minutes. The success rate was 93.33% (56/60). A retrospective analysis was conducted to assess the recovery of gallbladder function. All patients were followed up and symptom-free, without recurrence of the polyps; 3 months after the operation, the volume and contraction of the gallbladder recovered to preoperative levels. Thus the Endolap technique is reliable for removing benign gallbladder polyps and is applicable to a wider range of clinical situations than percutaneous polypectomy.

Acute pancreatitis is one of the most common gastrointestinal disorders worldwide. It requires acute hospitalization, with a reported annual incidence of 13 to 45 cases per 100,000 persons. In severe cases there is persistent organ failure and a mortality rate of 15% to 30%, whereas mortality of mild pancreatitis is only 0% to 1%. Treatment principles of necrotizing pancreatitis and the role of surgery are still controversial. Despite surgery being effective for infected pancreatic necrosis, it carries the risk of long-term endocrine and exocrine deficiency and a morbidity and mortality rate of between 10% to 40%. Considering high morbidity and mortality rates of operative necrosectomy, minimally invasive strategies are being explored by gastrointestinal surgeons, radiologists, and gastroenterologists. Since 1999, several other minimally invasive surgical, endoscopic, and radiologic approaches to drain and debride pancreatic necrosis have been described. In patients who do not improve after technically adequate drainage, necrosectomy should be performed. When minimal invasive management is unsuccessful or necrosis has spread to locations not accessible by endoscopy, open abdominal surgery is recommended. Additionally, surgery is recognized as a major determinant of outcomes for acute pancreatitis, and there is general agreement that patients should undergo surgery in the late phase of the disease. It is important to consider multidisciplinary management, considering the clinical situation and the comorbidity of the patient, as well as the surgeons experience.

BACKGROUND: Endoscopic biliary drainage is the palliative treatment of choice for malignant biliary hilar obstruction. There are conflicting opinions as to whether stents should be plastic or metal and whether stents should be unilateral or bilateral. AIM: To systematically review the literature on optimal endoscopic management of malignant hilar biliary obstruction. METHODS: A comprehensive search of several databases was carried out. A fixed-effect or a random-effect model was used to pool the data according to the result of a statistical heterogeneity test. RESULTS: Ten trials were enrolled. Compared with plastic stents, the use of metal stents was associated with a significantly higher successful drainage rate [odds ratio (OR) 0.26; 95% confidence interval (CI) 0.16-0.42; I2=40.3%], lower early complication rate (OR 2.92; 95% CI 1.65-5.17; I2=0%), longer stent patency [hazard ratio (HR) 0.43; 95% CI 0.30-0.61; I2=57.6%], and longer patient survival (HR 0.73; 95% CI 0.56-0.96; I2=56.9%). The unilateral biliary drainage group achieved a significantly higher successful stent insertion rate compared with the bilateral drainage group (OR 3.44; 95% CI 1.91-6.19; I2=0%), whereas no difference was observed between groups with respect to successful drainage rate (OR 1.73; 95% CI 0.89-3.37; I2=0%), early complications (OR 0.96; 95% CI 0.18-5.13; I2=60.4%), late complications (OR 1.41; 95% CI 0.54-3.67; I2=70.4%), stent patency (HR 0.57; 95% CI 0.19-1.73; I2=91.1%), and patient survival (HR 0.75; 95% CI 0.31-1.80; I2=94.3%). CONCLUSION: The performance of metallic stents was superior to that of plastic stents for hilar tumor palliation. Unilateral biliary drainage may be as effective as bilateral drainage for patients with hilar biliary obstruction.

PURPOSE: Controversy exists regarding the preferred biliary drainage technique in patients with Klatskin tumors because few comparative studies exist. This study compared outcomes of endoscopic biliary drainage (EBD) and percutaneous transhepatic biliary drainage (PTBD). MATERIALS AND METHODS: Consecutive patients (N = 129) with Klatskin tumors treated with initial EBD or PTBD were identified, and their clinical histories were retrospectively reviewed. The primary endpoint was the time to therapeutic success (TTS), defined as the time between the first drainage and a total bilirubin measurement of 40 µmol/L or lower. RESULTS: EBD was the first biliary decompression procedure performed in 87 patients; PTBD was performed first in 42. Technical success rates (78% with EBD vs 98% with PTBD; P = .004) and therapeutic success rates (49% vs 79%, respectively; P = .002) were significantly lower in the EBD group than in the PTBD group. Forty-four patients in the EBD group (51%) subsequently underwent PTBD before therapeutic success was achieved or antitumoral treatment was started. Median TTSs were 61 days in the EBD group and 44 days in the PTBD group, and multivariate analysis showed a hazard ratio of 0.63 (95% confidence interval, 0.41-0.99; P = .045). In patients treated with surgery or chemotherapy with or without radiation therapy, median times to treatment were 76 and 68 days in the EBD and PTBD groups, respectively (P = .76). Cholangitis occurred in 25% and 21% of patients in the EBD and PTBD groups, respectively (P = .34). CONCLUSIONS: PTBD should be seriously considered for biliary decompression when treating patients with Klatskin tumor.

BACKGROUND AND AIMS: Percutaneous endoscopic gastrostomy (PEG) provides enteral nutrition to patients who cannot swallow. Few studies have prospectively evaluated its long-term outcomes or eventual resumption of oral intake. METHODS: Consecutive PEG patients were prospectively recruited from a tertiary hospital over 12 months and followed until all had met the primary endpoints of death or resumption of oral diet with PEG extubation. Data was collected by standardised periodic phone interview. RESULTS: Forty patients (24 males, median age 74 years) were followed for up to 8.4 years (median 5.3 months, interquartile range [IQR] 13.6 months). The end-of-study mortality rate was 70% (median 6.8 months, IQR 19.9 months) and the only predictor of mortality was head injury as the indication for PEG (Cox regression HR 5.90, 95% CI: 1.2-28.4). At two years following PEG, 30% of patients had resumed oral intake (median 2.9 months, IQR 7.2 months) and 19% remained on PEG-feeding. Predictors of resumption of oral intake were the ability to tolerate some oral intake at 3 months (HR: 248.5, 95% CI: 8.7-7065.3) and 6 months (HR: 6.3, 95% CI: 1.03-38.9) but not at 12 months. Cumulative survival was highest for ear nose and throat (ENT) tumour and worst for acute head injury (log rank P = 0.048). CONCLUSIONS: Half of all PEG patients remained alive at 2 years using PEG or have resumed full oral intake. A supervised trial of oral intake at 3 or 6 months may help predict eventual resumption of per oral diet.

OBJECTIVE: Propofol sedation for mainly diagnostic endoscopic procedures has proved safe in recent trials, with no need for endotracheal intubation. However, there is evidence that cardiorespiratory side effects occur more frequently and that assisted ventilation may be necessary if propofol sedation is performed for interventional endoscopic procedures. MATERIAL AND METHODS: Over a 6-year period, all adverse events (defined as premature termination of the procedure due to sedation-related events or either the need for assisted ventilation or admission to ICU) occurring during 9547 endoscopic interventions (UGI, n = 5.374, ERCP, n = 3.937, EUS, n=236) under propofol sedation were assessed. RESULTS: A total of 135 adverse events (1.4%) were documented. Assisted ventilation was necessary in 40 patients (0.4%); 9 patients required endotracheal intubation (0.09%); 28 needed further monitoring on the ICU (0.3%); and 4 patients died, 3 potentially due to sedation-related side effects (mortality, 0.03%). Independent risk factors for sedation-related side effects were emergency endoscopic examinations and a total propofol dose >100 mg. CONCLUSIONS: Interventional endoscopy under propofol sedation is not risk-free. Increased attention must be focused on close monitoring of vital parameters, particularly when undertaking long-lasting interventions and emergency procedures.

This review summarises the data of current meta-analyses on the outcome of endoscopic and surgical biliary bypass procedures applied for inoperable pancreatic tumours. The authors suggest that plastic biliary stents should be used in cases only with short survival (less than six months). In patients with a prognosis of longer than six month, self-expandable metal stents are more cost-effective. This latter technique is as efficient as the traditional surgical bypass procedures. However, surgical bypass is preferable in cases if tumour resection is questionable after staging or in patients with gastric emptying problems.Furthermore, application of duodenal stents is suggested in selected cases only due to relatively frequent late complications (stent migration, perforation, obstruction). Duodenal stents can be used in patients with advanced stage disease or very high operative risk.

BACKGROUND AND STUDY AIMS: Natural orifice transluminal endoscopic surgery (NOTES) is a potentially less invasive alternative to laparoscopic surgery that may be applicable to distal pancreatectomy. We aimed to demonstrate the technical feasibility of a NOTES distal pancreatectomy in an in vivo porcine model via a combined transvaginal-transcolonic approach. MATERIAL AND METHODS: The procedure was performed in five female Yorkshire pigs weighing approximately 30 kg each. A prototype endoscope ("R-scope"), advanced into the peritoneal cavity through an anterior colotomy, and a computer-assisted linear stapler, introduced transvaginally, were used in dissection and resection of the distal pancreas. Prone positioning was used to enhance retroperitoneal exposure. Pneumodissection was used for blunt dissection. The colotomies were closed with endoloops. Necropsies were done immediately after the procedure in the first three animals, and after 2 weeks' survival in the final two animals. RESULTS: Distal pancreatectomy was successful in all five animals. Prone positioning was critically important for proper exposure of retroperitoneal and pelvic structures. Pneumodissection was effective for blunt dissection, and both the linear stapler and R-scope functioned smoothly. Transvaginal and transcolonic access provided similar intraperitoneal views, and the dual-lumen approach enhanced triangulation. Both survival animals thrived postoperatively. Necropsies revealed clean staple lines; closed transcolonic and transvaginal incisions; and absence of infection, hemorrhage, or fluid collections. CONCLUSIONS: NOTES distal pancreatectomy is technically feasible in the porcine model. The transvaginal approach provides a vantage point very similar to that of the transcolonic route and holds promise as a NOTES access site, either singly or as part of a dual-lumen approach. The endoscopic linear stapler and R-scope both advance NOTES capabilities. The novel concepts of fully prone positioning, pneumodissection, and endoloop colotomy closures are introduced. Considering anatomical differences and that healthy animals were used, transferring this technique to patients with pancreatic disease might be difficult and further modifications would likely be needed.

BACKGROUND: The importance of rural operations is magnified by super-specialization, uneven geographic distribution, and special educational needs. Definition of practice patterns and quality measures are needed. METHODS: A statewide network of 60 operative specialists studied costs, quality, and outcomes in 17,319 patients undergoing 46 different specialty operations between 1998 and 2003, comparing 9,544 rural to 7,775 urban patients. These data are augmented by additional data from 5,339 operative patients in 2004. RESULTS: Both high volume rural and urban surgeons achieved fewer deaths than less frequent practitioners of colon or rectal resections (2/309 vs 5/167). Urban surgeons had sicker patients undergoing more extensive procedures, and used fewer consultations, but had more complications and reoperations. Laparoscopic cholecystectomy had similar outcomes with 5 deaths among 1,788 patients. Urban surgeons converted to an open procedure more frequently, whereas rural surgeons used hepatobiliary iminodiacetic acid (HIDA) scans as indication for cholecystectomy more often (P < .01). Indications for upper and lower endoscopy varied, but abnormalities were noted in 64%; only 11 of 6,938 patients undergoing endoscopy were admitted for complications, 5 required operations, 3 due to totally obstructing cancers. Hysterectomy, urologic procedures, and tympanostomy had admission/readmission rates as low as 1/400. Documented patient preoperative education occurred in 94% of both groups. Overall, performance measures were addressed more consistently by rural surgeons (P < .001). CONCLUSIONS: Operative practice reaches high standards in both settings; indications for operations vary, and rural practice is broader than urban practice. Rural surgeons exceed their urban colleagues on some quality process measures.

BACKGROUND: Adenomas of the duodenal papilla are rare. Because of their malignant potential, resection is mandatory. Options for resection include endoscopic resection techniques, transduodenal local excision, and pancreaticoduodenectomy. The aim of this retrospective study was to evaluate the safety and outcome of endoscopic snare resection of papillary adenomas in a Greek cohort of patients. METHODS: Fourteen patients (six women and eight men; age range, 42-76 years) were referred for endoscopic management of ampullary adenomas. A questionnaire was completed for each patient, which included preoperative and postoperative data points. Presenting symptoms were jaundice (n = 4), cholangitis (n = 1), and pain (n = 2). Seven patients were asymptomatic. If there was no common bile and main pancreatic duct invasion and the appearance suggested a benign lesion, biductal sphincterotomy onto normal duodenal tissue was performed. The adenomas were resected via a diathermy snare, along with the major papilla, after elevation of the lesion by epinephrine plus dextrose 50% (1:10,000) solution. At the discretion of the endoscopist, a biliary or pancreatic stent was inserted as a prophylactic procedure immediately after excision. RESULTS: Histopathologically, resected tissue included 11 adenomas and three adenomas with focal malignancy, referred for pancreaticoduodenectomy. Immediate complications were moderate bleeding (n = 1) and mild pancreatitis (n = 1). No procedure-related death occurred. Follow-up was available for 11 patients (mean, 28.36 months; range, 6-72). Pancreatic and biliary stents were placed in four and nine patients, respectively. Follow-up endoscopy revealed recurrent/residual adenomatous tissue in two patients (18%), which was resected endoscopically. CONCLUSION: Endoscopic snare resection of adenomas of the major duodenal papilla is a safe, well-tolerated alternative to surgical therapy. In expert hands, complications are mild and may be avoided by pre-resection biductal sphincterotomy, stent placement, and elevation of the lesion by epinephrine plus dextrose 50% solution injection.

BACKGROUND: Frey's operation is indicated on patients with chronic pancreatitis who have "head dominant" disease and involves resection of the head of pancreas and lateral pancreaticojejunostomy (LRLPJ). There is little information about the postoperative complications after this procedure and the factors likely to be responsible for them. This paper addresses this aspect of LRLPJ. METHODS: A retrospective review was made of records of 41 patients undergoing LRLPJ for chronic pancreatitis between January 1990 to June 2003. RESULTS: Sixteen (39%) patients had 19 complications in the early postoperative period; septic complications were the commonest. One patient died. Regression analysis showed preoperative endoscopic pancreatic stenting to be the factor responsible for majority of these complications (P = 0.0041). Patients with a history of pancreatic stenting had a prolonged hospital stay (P = 0.022). CONCLUSIONS: Postoperative complications after LRLPJ are usually septic in nature and are likely to occur more often in patients in whom endoscopic pancreatic stenting has been performed before surgical intervention.
