Abstract
BACKGROUND The aim of the study was to evaluate the results of laparoscopic adjustable gastric banding (LAGB) in patients lost to follow-up. METHODS Patients lost to follow-up were identified from a consecutive cohort of 495 patients who underwent LAGB between November 1995 and September 2006. These patients were asked to return to follow-up and their actual weight was assessed. RESULTS Of 93 patients lost to follow-up, 73 were motivated to reattend. Of these, 60 per cent (44 patients) had lost less than 25 per cent of excess weight, compared with 16.3 per cent (P < 0.001), 27.0 per cent (P < 0.001) and 42 per cent (P = 0.026) of patients after 2, 4 and 8 years of regular follow-up. CONCLUSION Patients lost to follow-up are more likely to have poor weight loss, emphasizing the importance of follow-up after LAGB. Outcome after surgery for morbid obesity should include patients lost to follow-up as a measure of overall success.

Abstract
Controversial opinions exist concerning the effect of laparoscopic adjustable gastric banding on gastroesophageal reflux. MEDLINE and EMBASE databases were searched for relevant studies on patients undergoing adjustable gastric banding. Data are expressed in mean (range). Twenty studies were identified with a total of 3307 patients. The prevalence of reflux symptoms decreased postoperatively from 32.9% (16-57) to 7.7% (0-26.9) and medication use from 27.5% (16-38.5) to 9.5% (3.1-19.2). Newly developed reflux symptoms were found in 15% (6.1-20) of the patients. The percentage of esophagitis decreased postoperatively from 33.3% (19.4-61.6) to 27% (2.3-60.8). Newly developed esophagitis was observed in 22.9% (0-38.4). Pathological reflux was found in 55.8% (34.9-77.4) preoperatively and postoperatively in 29.4% (0-41.7) of the patients. Lower esophageal sphincter pressures increased from 12.9 to 16.9 mmHg (11.3-21.4). Lower esophageal sphincter relaxation decreased from 100% to 79.7% (58-86). The percentage of dysmotility increased from 3.5% (0-10) to 12.6% (0-25). Adjustable gastric banding has anti-reflux properties resulting in resolution or improvement of reflux symptoms, normalized pH monitoring results and a decrease of esophagitis on short term. However, worsening or newly developed reflux symptoms and esophagitis are found in a subset of patients during longer follow-up.

Abstract
BACKGROUND The percutaneous transgluteal approach is a well-accepted method for drainage of deep pelvic abscesses. Recently, in 3 patients, transgluteal drainage was complicated by the development of large gluteal abscesses requiring multiple surgical interventions. METHODS This report describes these cases as well as a search of the literature. RESULTS Three patients with a complicated clinical course after colon resection are described. After CT-guided percutaneous transgluteal drainage of the pelvic abscess, large gluteal abscesses were diagnosed after 2-6 weeks. Subsequent surgical interventions were needed to adequately drain these abscesses. In the literature, transgluteal drainage of pelvic abscesses is well described as a safe and efficient method. However, until now the development of gluteal abscesses has not been mentioned as a complication in the literature. CONCLUSION In our own experience, a transrectally (radiologically or surgically performed) drainage route is recommended in patients who develop a deep pelvic abscess after bowel resection and suspicion of an anastomotic leak.

Abstract
We present a 61-year-old woman with hypovolemic shock due to a ruptured aneurysm of the superior posterior pancreatic-duodenal artery in whom recurrent syncopes were the first presenting sign of pancreatic-duodenal artery aneurysm (PDAA). PDAA is a rare but life-threatening condition. The widely varying symptomatology may lead to a delay in diagnosis and treatment. Patients with atypical symptoms, such as vague abdominal pain, recurrent dizziness or syncope, may actually suffer from a sentinel bleeding of the vascular malformation. Radiological imaging, especially selective angiography, may provide a diagnostic as well as a therapeutic tool in these patients.

Abstract
BACKGROUND & AIMS There is abundant evidence that the routine use of nasogastric decompression following elective abdominal surgery is ineffective in achieving any goals it is intended for. Nevertheless its use is still standard of care. The aim of the present study was to investigate whether it is possible to ban nasogastric decompression after elective colonic surgery. METHODS At first baseline measurements concerning elements of perioperative care, including nasogastric tubes, were recorded retrospectively over the year 2004. In 2006-2007 the implementation of a fast-track colonic surgery project was guided by the Dutch Institute for Quality of Healthcare CBO, using Berwick's Breakthrough approach. RESULTS A total of 2007 patients were enrolled. The baseline measurement showed that the use of nasogastric drainage is still common practice in the Netherlands. 953 patients (88.3%) had a nasogastric tube postoperatively. That tube was removed after a median of 2.5 days (range 1-3 days). After the implementation of the Perioperative Care Breakthrough project the percentage of patients having a nasogastric tube postoperatively dropped to 9.6% (p<0.0001). CONCLUSIONS Our results show using the Breakthrough Methodology it is possible to eradicate the inappropriate routine use of NG tubes.

Abstract
OBJECTIVE To evaluate whether enteral prophylaxis with probiotics in patients with predicted severe acute pancreatitis prevents infectious complications. DESIGN Multicentre, randomised, double-blind, placebo-controlled trial. METHOD A total of 296 patients with predicted severe acute pancreatitis (APACHE II score > or = 8, Imrie score > or = 3 or C-reactive protein concentration > 150 mg/l) were included and randomised to one of two groups. Within 72 hours after symptom onset, patients received a multispecies preparation of probiotics or placebo given twice daily via a jejunal catheter for 28 days. The primary endpoint was the occurrence of one of the following infections during admission and go-day follow-up: infected pancreatic necrosis, bacteraemia, pneumonia, urosepsis or infected ascites. Secondary endpoints were mortality and adverse reactions. The study registration number is ISRCTN38327949. RESULTS Treatment groups were similar at baseline with regard to patient characteristics and disease severity. Infections occurred in 30% of patients in the probiotics group (46 of 152 patients) and 28% of those in the placebo group (41 of 144 patients; relative risk (RR): 1.1; 95% CI: 0.8-1.5). The mortality rate was 16% in the probiotics group (24 of 152 patients) and 6% (9 of 144 patients) in the placebo group (RR: 2.5; 95% CI: 1.2-5.3). In the probiotics group, 9 patients developed bowel ischaemia (of whom 8 patients died), compared with none in the placebo group (p = 0.004). CONCLUSION In patients with predicted severe acute pancreatitis, use of this combination of probiotic strains did not reduce the risk of infections. Probiotic prophylaxis was associated with a more than two-fold increase in mortality and should therefore not be administered in this category of patients.

Abstract
A 45-year-old woman, known to have a congenital exstrophy ofthe bladder, for which she underwent a ureterosigmoidostomy in her infancy, presented with fever. This was due to pyelonephritis, from which she recovered with antibiotic therapy. During colonoscopy a carcinoma of the sigmoid was found at the level of the anastomosis of the ureters. Patients with a ureterosigmoidostomy have a one hundred-fold increased risk of colon carcinoma compared to the general population. The development of malignant tumours as a long-term complication of this procedure is linked with the frequent contact between intestinal tissue and urine. Periodical colonoscopy of these patients is advised.

Abstract
Intense adrenal enhancement has previously been reported in patients with hypovolemic and septic shock. The purpose of this study was to assess whether this computed tomography (CT) finding is also observed in patients presenting with severe acute pancreatitis and early organ failure. A retrospective analysis of a prospectively collected database was performed. Out of 38 consecutive patients with predicted severe acute pancreatitis, 3 patients showed intense bilateral adrenal enhancement on early CT. All patients had early multiple organ failure and subsequently died. In two cases, pathologic correlation was obtained. Intense adrenal enhancement may be a new prognostic indicator in patients with acute pancreatitis, particularly when organ failure is present at the time of CT examination. Further studies are necessary to confirm this observation.

Abstract
OBJECTIVE To analyse the results of the laparoscopic adjustable gastric banding (LAGB) procedure for morbid obesity. DESIGN. Retrospective, descriptive. METHOD From November 1, 1995 to May 31, 2005, laparoscopic adjustable banding surgery was performed in St. Antonius Hospital, Nieuwegein, the Netherlands, in 411 patients. Inclusion criteria were BMI > or = 40 kg/ m(2) or BMI > 35 kg/m(2) and severe comorbidity with > 3 attempts at weight loss in the past. Selection, inclusion and follow-up were performed in a specialised, multidisciplinary setting. Height, weight, and complications were prospectively recorded. In 1995-2000 the perigastric surgical procedure was used and in 2000-2005 the pars-flaccida method. RESULTS The study group consisted of 350 (85%) women and 61 (I5%) men with a median age of 38 years (range 17-60). Out of these 411 patients, the median weight was 133.4 kg, the median overweight, 69.6 kg and the median BMI 46.3 kg/m2. Two years after surgery, data was known for 267 patients where 206 (77%) had a weight loss > 30%, and 7 patients (3%) a weight gain. The median BMI difference was then -10.2 kg/m2 (range +4.7--26.4). The median loss of overweight was 46.3% (+10.00--97.8). The weight loss remained stable in the following years. The most commonly seen complications were fundus slippage (13%) and port-a-cath related complications (7%). These occurred more often in patients who had had the perigastric method surgery than in the parsflaccida surgical method. CONCLUSION Three quarters of the patients with morbid obesity who received laparoscopic gastric banding surgery had achieved and sustained weight loss at 2 years following surgery. The pars-flaccida method resulted in fewer complications than the perigastric surgical method.

Abstract
Obesity results in several health problems, the most important of these being diabetes mellitus type 2. In patients with morbid obesity (BMI > or = 35 kg/m(2) and comorbidity or BMI > or = 40 kg/m(2)) in particular, prevention or treatment of health problems resulting from the obesity is only possible with considerable and lasting weight loss. Gastric reduction surgery with the adjustable gastric band has been shown to be safe and effective. This is also true for the more invasive techniques such as the gastric bypass and the biliopancreatic diversion. Surgical treatment is the only treatment that can induce substantial and lasting weight loss (> 50% of the excess weight, on average) in this patient group in the long run. Although the availability of surgical treatment is as yet inadequate in the Netherlands, it has recently improved considerably. Reimbursement of the treatment is however still an obscure issue and the reimbursement of the follow-up is uncertain. Possibly, the current experiments with independent treatment centers will be able to put an end to this uncertainty.

Abstract
OBJECTIVE The objective of this study was to systematically evaluate the molecular basis of the association between visceral fat mass and plasma plasminogen activator inhibitor-1 (PAI-1) levels in man. DESIGN A comprehensive approach comprising observational, in vitro, and human intervention studies. MEASUREMENTS AND RESULTS We confirmed an exclusive relationship between visceral fat and plasma PAI-1 levels (r=0.79, P<0.001) and corroborated preferential PAI-1 release from adipose tissue explants. Yet, messenger RNA analysis and in vivo measurement of PAI-1 release from visceral fat (AV-differences over the omentum) not only excluded visceral adipose tissue as a relevant source of circulating PAI-1, but also excluded visceral fat as a significant source of proinflammatory mediators such as tumor necrosis factor-alpha, IL-1 or transforming growth factor-beta that could induce PAI-1 expression in tissues other than visceral fat. Short-term interventions with acipimox and growth hormone (GH) as well as statistical evaluation excluded free fatty acids and GH as metabolic links. Further analysis of the metabolic data in a stepwise regression model indicated that plasma PAI-1 levels and visceral fat rather are co-correlates that both relate to impaired lipid handling. CONCLUSION Our PAI-1 studies show that visceral fat mass and plasma PAI-1 levels are co-correlated rather than causatively related, with lipid load as common denominator.

Abstract
Abstract
Background
Minimally invasive procedures to treat infected necrotizing pancreatitis (INP) are gaining popularity. The proportion of patients suitable for this approach remains unknown.
Methods
Preoperative computed tomography (CT) scans were reviewed from 106 consecutive patients who had surgery for INP between 2000 and 2003 in 11 Dutch hospitals. Collections related to the pancreas were classified according to their distance from the left abdominal wall. Five radiologists judged ‘accessibility’ for drain placement and the likelihood that there was a fluid component that would drain (‘drainability’). Agreement between radiologists was determined.
Results
CT scans of 80 (75 per cent) patients were available (59 men; age range 29–80 years). The median interval between hospital admission and preoperative CT scan was 20 days. In 55 (69 per cent) patients, the lateral border of the collection was less than 5 cm from the left abdominal wall. Placement of a drain was deemed feasible in 67 (84 (range 77–89) per cent) patients; mean(s.d.) kappa 0·428(0·096). In 45 (56 per cent) patients, a drain could be placed through the left retroperitoneum. In 43 (54 (range 49–82) per cent) patients, collections were judged to contain a drainable fluid component. Interobserver agreement on ‘drainability’ was poor, mean(s.d.) kappa 0·289(0·101).
Conclusion
Most peripancreatic collections in INP were considered accessible to a minimally invasive approach.

Abstract
Surgical intervention in patients with infected necrotizing pancreatitis generally consists of laparotomy and necrosectomy. This is an invasive procedure that is associated with high morbidity and mortality rates. In this report, we present an alternative minimally invasive technique: videoscopic assisted retroperitoneal debridement (VARD). This technique can be considered a hybrid between endoscopic and open retroperitoneal necrosectomy. A detailed technical description is provided and the advantages over various other minimally invasive retroperitoneal techniques are discussed.

Abstract
BACKGROUND In western countries, laparoscopic gastric banding is increasingly used in the surgical treatment of morbid obesity. This study aimed to investigate the feasibility, safety, morbidity, and costs of an outpatient procedure (OP) compared with an overnight stay (OS). METHODS In a 2-year period, 50 consecutive patients were randomized to an OP group or an OS group. RESULTS In the OP group, 76% of the patients were successfully discharged the same day, without readmissions. Four procedures were converted, and one complication occurred. The patients in the OP group seemed to experience more pain (p = 0.009). Satisfaction scores were 8.1 (OP) and 8.8 (OS) (p = 0.06). Half of the OP patients and most of the OS patients preferred a clinical admission. The OP treatment cost 600 euros less than OS. CONCLUSION With proper patient selection, laparoscopic gastric banding can be performed safely and at lower cost as an outpatient procedure.

Abstract
BACKGROUND Alterations in esophageal motility may occur after placement of an adjustable gastric band as treatment for morbid obesity, near the gastro-esophageal junction. It causes an outlet obstruction, especially during follow-up after the band is filled. METHODS 29 morbidly obese patients underwent conventional manometry preoperatively, 6 weeks postoperatively before and after filling the band and at 6 months postoperatively. A questionnaire was used to assess upper gastrointestinal symptoms during follow-up. RESULTS After band placement, there was a significant increase in lower esophageal sphincter (LES) end-expiratory pressure at 6 weeks with an empty band: 1.3 (0.9-1.9) kPa (median (interquartile range) (P=0.003), 6 weeks with a filled band: 2.1 (1.5-2.8) kPa (P=0.0001), and at 6 months: 1.5 (1.3-1.9) kPa (P=0.001), compared to the preoperative pressure: 0.8 (0.6-1.3) kPa. Also after band placement, the high pressure zone length increased (preop 5.0 (4.3-6.0) cm vs 6 weeks 6.0 (5.0-6.5) cm (P=0.003). The propagation of peristaltic contractions was not significantly altered after band placement. Heartburn decreased 6 weeks postoperatively (P=0.04) but increased at 6 months. Heartburn at 6 months was correlated with pouch formation (0.667; P<0.01). CONCLUSION Adjustable gastric band placement causes an increase in LES pressure and length of the high pressure zone. It decreases reflux symptoms in the short-term, but this effect appears not to be related to an effect on LES pressure or length. Pouch formation increases reflux symptoms without having any relationship to LES pressure and length. Band placement in the short-term does not disturb propagation of esophageal contractions.

Abstract
Three patients, men aged 49, 62 and 33 years, were admitted with acute abdominal symptoms due to necrotising pancreatitis. They underwent multiple interventions during a hospital stay of several months, but ultimately recovered completely. In case of infected (peri-)pancreatic necrosis, intervention is required. Good clinical judgement in the differentiation between the septic inflammatory-response syndrome, sepsis and infected necrosis as the cause of the clinical condition is important. Because of the different intervention strategies, treatment by a team comprising a radiologist, gastroenterologist, intensive care specialist and gastrointestinal surgeon is required. Randomised studies on intervention in infected pancreatic necrosis are lacking. In 2002, to improve the treatment of patients with acute (necrotising) pancreatitis via a combination of research, consultation and centralisation, the Dutch Acute Pancreatitis Study Group was formed.

Abstract
BACKGROUND The aim of this study was to examine postoperative as well as retrospective preoperative evaluations of multiple dimensions of quality of life of patients with morbid obesity after laparascopic adjustable gastric banding (LAGB). METHODS 12 to 38 months after LAGB, 74 consecutive patients (64 female, 10 male, mean age 36.6 years, age range 23-56) filled out the RAND-36 Health Survey questionnaire to evaluate their current postoperative as well as their past preoperative quality of life. RESULTS Pre- to 1 year postoperative weight reduction (127.5 to 100.7 kg) and change of BMI (45.2 to 35.6 kg/m2) were highly significant (p<0.001). As compared to age reference groups, the preoperative quality of life was evaluated very poor (p<0.002), postoperative psychological and social quality of life were about normal (all p's >0.10), and postoperative physical functioning (p=0.04), vitality (p=0.01) and general health (p=0.03) were below normal. No differences were found between postoperative evaluations of patient groups with varying postoperative follow-up duration, but patients in the second year after surgery evaluated some aspects of their preoperative quality of life as poorer than patients in the third year after surgery. CONCLUSION Postoperative psychosocial quality is at a level that may be expected to motivate patients to consolidate the surgically established weight reduction, but attention should be paid to the physical condition. Since the relative gain in quality of life as experienced by patients tends to be evaluated less with a longer duration of the postoperative interval, the risk of relapse may increase with passage of time.

Abstract
OBJECTIVE To assess the difference in safety of laparoscopic cholecystectomy performed by residents and staff surgeons. SETTING St. Antonius Hospital, Nieuwegein, the Netherlands. DESIGN Retrospective study. METHOD Results of 649 laparoscopic cholecystectomies performed by staff surgeons experienced in laparoscopic surgery, by residents under supervision of a staff surgeon, by residents without supervision and by inexperienced surgeons, were compared. RESULTS Patients were comparable, except for liver function disorders and raised sedimentation rates, of which there were more in the group operated by the non-supervised residents, compared with the staff surgeons. Average operation time was 57 minutes in all four groups. Non-supervised residents had more retained stones than staff surgeons (19 vs 6%) and reported more bleeding during surgery than staff surgeons (21 vs 8%). Conversion rate was the same (3.9%) in all four groups. Complications occurred in 5.7%; this also was the same in the four groups. CONCLUSION Residents following a traditional surgical training without practice on animals, perform laparoscopic cholecystectomy as quickly as and with the same conversion and complication rates as their teachers.

Abstract
OBJECTIVES To study the development and progression in time of deep venous valve incompetence with Duplex ultrasonography in combination with distal cuff deflation in patients with a history of deep venous thrombosis (DVT) and to evaluate symptoms of chronic venous insufficiency (CVI). DESIGN Prospective cohort study. MATERIALS AND METHODS In a long term follow-up study the deep venous system of 24 patients (7 men, 17 women, mean age 51 years) of an initial group of 27 with phlebographically documented deep venous thrombosis were examined with Duplex scanning at two intervals (mean 34 and 86 months) after DVT. RESULTS All but one segments recanalised. Deep venous incompetence occurred exclusively in post-DVT segments. At first follow-up 48% of the post-thrombotic segments showed valve incompetence, while at second follow-up this had increased to 60% (p < 0.001). Venous segments of the upper leg mainly contributed to this increase. Our group of 24 patients was too small to find any significant correlation between symptoms, thrombosis and valvular incompetence. CONCLUSIONS The development of deep vein valve incompetence after deep vein thrombosis is a progressive process over more than 5 years.

Abstract
PURPOSE Duplex ultrasonography with distal cuff deflation was used to establish the physiologic reflux duration in different segments of the deep venous system in healthy individuals, and to document the occurrence of deep vein valve incompetence in patients after deep vein thrombosis (DVT). METHODS Two hundred fifty-two vein segments in 42 legs of 21 healthy individuals and 160 deep vein segments in 27 patients with phlebographically documented DVT were examined with duplex scanning. RESULTS The duration of reflux in healthy subjects was significantly shorter in distal deep vein segments. Ninety-five percent of the values were less than 0.88, 0.8, 0.8, 0.28, 0.2, and 0.12 seconds, respectively, for the common femoral, superficial femoral, deep femoral, popliteal, and posterior tibial vein (at midcalf and ankle level). The 95 percentile for reflux duration in the superficial venous system was 0.5 seconds for all vein segments, regardless of the location. No significant correlation was found between the reflux peak flow velocity and reflux duration (R = 0.6). The reflux peak flow velocity is therefore not useful as a parameter of the degree of reflux. The patient group was examined with an interval of 18 to 51 months (mean 34 months) after DVT. Forty-five percent of the initially affected segments showed valve incompetence at follow-up (n = 54); only three of 40 segments initially free from thrombus showed pathologic reflux at follow-up (p < 0.01). Reflux durations in most of the incompetent vein segments were two or more times the normal value of reflux duration. The highest prevalence of valve incompetence was found in the superficial femoral and popliteal vein segment (p < 0.01). None of the patients showed valve incompetence at all levels of the deep venous system. A significant (p = 0.04) relation was found between the extent of the initial thrombosis and the number of refluxing vein segments at follow-up, but no correlation was found between the extent of initial thrombosis and the late clinical symptoms (p = 0.16); clinical symptoms could not be related to the number of incompetent vein segments. CONCLUSIONS Duplex scanning allows a good discrimination between physiologic and abnormal reflux duration and is an important tool in the evaluation of the postthrombotic limb. Early assessment after DVT may have prognostic value in individual patients.

Abstract
In a prospective study the diagnostic value of compression ultrasonography (CUS) versus Duplex scanning (DS) in the non-invasive detection of acute femoropopliteal deep venous thrombosis (DVT) was determined. In 114 eligible patients clinically suspected of DVT of the lower extremity, compression ultrasonography and Duplex scanning were performed within 24 hours by different assessors unaware of the outcome of the other test. In 109 patients concordant results of combined compression ultrasonography and Duplex scanning were obtained and considered as a proof of the absence or presence of deep venous thrombosis and no subsequent invasive investigations were performed. In five patients compression ultrasonography and Duplex scanning were discordant and contrast venography was performed. Femoropopliteal thrombosis was present in 47 legs (41%). The sensitivity, specificity and accuracy of compression ultrasonography were 93.6, 97.0 and 95.6%, respectively, and of Duplex scanning 100, 98.5 and 99.1%, respectively. We conclude that compression ultrasonography and Duplex scanning are methods with comparably high accuracy. Because of its availability, accuracy, cost-effectiveness and simplicity we recommend compression ultrasonography as the primary diagnostic test in the detection of deep venous thrombosis.
