[Symptomatic gallstone disease: an indication for surgery].

Three patients, men in the ages of 58, 66 and 56 years, respectively, had experienced 'warning colics' a considerable time before gallstone complications or severe recurrent colic. Ultrasonographically proven gallstones had not led to cholecystectomy. The 58-year-old man died of sepsis due to infected pancreatic necrosis; the other men underwent laparoscopic cholecystectomy, after which they recovered fully. Approximately 10-5% of the adult Dutch population have gallstones, but only 10% will develop symptoms. The annual risk for developing complicated gallstone disease is 1-2% in asymptomatic gallstone carriers. Of patients admitted with complicated gallstone disease, 58% have had prior 'warning colics'. Complicated gallstone disease can be prevented by timely treatment after recognition of warning colics. Cholecystectomy is indicated in patients with intermittent upper-abdominal pain and proven gallstones or sludge.

[A nationwide Dutch study into the optimal treatment of patients with infected necrotising pancreatitis: the PANTER trial].

Surgical intervention in infected necrotising pancreatitis generally consists of necrosectomy via laparotomy. The morbidity and mortality after this procedure might be reduced by minimally invasive strategies. The 20 hospitals of the Dutch Acute Pancreatitis Study Group are currently enrolling patients in a randomised trial to compare (a) laparotomy with necrosectomy and continuous postoperative lavage with (b) CT-guided or endoscopic transgastric drainage, if necessary, followed by videoscopic assisted retroperitoneal debridement (VARD): the PANTER trial ('pancreatitis, necrosectomy versus a minimally invasive step-up approach'). The primary endpoint is the proportion of patients suffering from major postoperative morbidity and mortality. Patients with (suspected) infected necrotising pancreatitis can be put forward for participation in the trial in one of the 20 participating centres.

[Potential role for probiotics in the prevention of infectious complications during acute pancreatitis].

Acute pancreatitis has a high mortality in case of secondary infection of (peri-)pancreatic necrosis. Bacterial translocation is held responsible for the majority of these infectious complications of severe acute pancreatitis. Prophylactic strategies should therefore be directed at the three most important pathophysiological mechanisms of bacterial translocation: disturbed small-bowel motility and bacterial overgrowth, failure of the mucosal barrier function and a disturbed response of the immune system. In-vitro studies and research in experimental animals have shown that specially selected probiotics exert an effect on these mechanisms and can prevent bacterial translocation. Recently, several randomised, double-blind, placebo-controlled trials evaluating prophylactic treatment with enteral probiotics have shown good results. A Dutch multicentre trial, 'Probiotics in pancreatitis trial' (PROPATRIA), is currently underway.

[Timing and choice of intervention in necrotising pancreatitis].

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.

Colonic involvement in acute pancreatitis. A retrospective study of 16 patients.

BACKGROUND: Diagnosis of colonic pathology complicating acute pancreatitis is difficult. Several pathogenetic mechanisms have been proposed. The treatment of choice is resection of the affected segment. Current theories on diagnosis, pathogenesis, and treatment were reviewed. METHOD: Retrospectively, 16 patients with severe acute pancreatitis and colonic complications (1988-2001) were included. Preoperative CT scans and specimens of removed colonic segments were reviewed by a blinded radiologist and pathologist respectively. RESULTS: Sixteen patients underwent partial colectomy for suspected imminent or overt perforation, based on the outer aspect of the colon. Four patients had a macroscopic perforation during surgery. Retroperitoneal spread of the necrotizing process to the colon was seen in all 10 reviewed CT scans. All 14 microscopically examined specimens showed fat necrosis and pericolitis. Of these, 4 had ischemia and 6 showed subserosal hemorrhage. Eight specimens had intact mucosa, submucosa and smooth muscle layers. Eleven patients died. Secondary anastomosis in surviving patients did not induce further mortality. CONCLUSION: Spread of pancreatic enzymes and necrosis is the major cause for colonic pathology in acute pancreatitis. Outside inspection of the colon during surgery is unreliable to detect ischemia or imminent perforation. To prevent colonic complications during follow-up, low-threshold colonic resection seems justified.

Surgical management of acute necrotizing pancreatitis: a 13-year experience and a systematic review.

BACKGROUND: The course of acute pancreatitis (AP) is unpredictable and can vary from mild to lethal. Mortality varies from low (<2%) in mild cases to high (20%-70%) in the case of infected pancreatic necrosis. Surgical management has not been investigated in well-designed trials. Based on literature review and retrospective results from our institution, recent insights are summarized and recommendations concerning surgical treatment of AP are given. METHODS: Data of patients who underwent necrosectomy for AP in our hospital in the period 1988-2001 were reviewed. Surgical treatment strategy was divided into open abdomen strategy (OAS) and primary closure with continuous postoperative lavage (CPL). An extensive database literature search was performed to obtain articles on surgical management of AP. Level 5 evidence articles were excluded. RESULTS: In our institution, 38 patients were treated with OAS and 21 with CPL. Mortality was high (47% in the OAS group and 33% in the CPL group). The primary cause of mortality was multiorgan failure. Only 50 manuscripts from the literature search contained useful data. Mortality of patients with OAS and CPL treatment was 27% and 15%. respectively. Fewer cases of gastro-intestinal fistulas. bleeding and re-interventions were reported with CPL. The majority of all survivors regained a good quality of life. CONCLUSION: Mortality of acute necrotizing pancreatitis remains high, despite optimal surgical and medical treatment. Current surgical practice is not based on well-designed clinical trails. Randomized studies are needed to define evidence-based surgery in acute necrotizing pancreatitis.

Long-term results after laparoscopic Thal procedure in children.

As the laparoscopic approach to gastroesophageal reflux disease (GERD) was introduced in pediatric surgery in the last decade of the 20th century, it became apparent that this approach was beneficial. The favorable results have led to a more general acceptance and implementation of this type of surgery at the beginning of the 21st century. We give an overview of the first decade of laparoscopic antireflux procedures in children with an emphasis on the laparoscopic Thal fundoplication and its implication on morbidity and cure of GERD in the long term both for normal and mentally handicapped children. Between 1993 and 2002, 149 children with GERD underwent 157 laparoscopic antireflux procedures, of whom 48% were mentally handicapped. Follow-up ranged from 6 months to 9 years (median age 4.5 years). Nineteen children died. All but one were not related to the antireflux procedure. Immediate relief of symptoms occurred in 120 children (80.5%). In 29 children, the results were less than optimal. Eight patients underwent a laparoscopic redo procedure (5.4%). However, none of the children with a follow-up of more than 5 years show any symptoms anymore. In conclusion, the laparoscopic Thal fundoplication is a safe procedure, and results in the long term are favorable, irrespective of the nature of the cause, ie, mental retardation.

Beneficial effects of ERCP and papillotomy in predicted severe biliary pancreatitis.

BACKGROUND/AIMS: Extensive circumstantial evidence indicates that patients with a predicted severe attack of acute biliary pancreatitis (ABP) should undergo an endoscopic retrograde cholangiography with papillotomy (ERC/PT). However, in clinical practice this procedure is not always performed. This study was conducted to compare outcome in patients with and without ERC/PT. METHODOLOGY: Thirty-five of 80 patients admitted with ABP had a predicted severe attack (three or more Ranson criteria). Only in 24 of these 35 patients was an ERC/PT performed. RESULTS: In the ERC/PT group, significantly less pancreatic necrosis (8 vs. 64%, p<0.001) occurred, hospital stay was shorter (median 22 +/- 5 vs. 51 +/- 19 days, P=0.08) and mortality was lower (8 vs. 36%, P=0.01). Twenty-three patients (66%) underwent cholecystectomy after a median period of 10 weeks (range 0-26 weeks) after discharge. During the waiting period, in the ERC/PT group, two patients developed acute cholecystitis whereas recurrent ABP and common bile duct stones occurred in one patient each. CONCLUSIONS: In patients with a predicted severe attack of ABP, performing ERC/PT is associated with less morbidity and lower mortality.
