Symptom profiles and palliative care in advanced pancreatic cancer: a prospective study.

OBJECTIVES: To describe prospectively the prevalence and severity of disease-related symptoms, quality of life (QOL) and need for palliative care in patients with advanced pancreatic cancer. PATIENTS AND METHODS: Fifty-one patients treated for advanced pancreatic cancer filled in the Edmonton Symptom Assessment Scale (ESAS) for symptom registration and the EORTC QLQ-C30 and QLQ-PAN26 quality of life questionnaires at first contact (baseline) and the ESAS in the following consultations. Need for palliative interventions were registered. RESULTS: Of the 22 women and 29 men (mean age, 62 years), 20 had locally unresectable cancer, 19 had metastatic disease, and 12 had recurrent disease after curative resection. Forty-six patients died during follow-up (median survival, 99 days). At baseline, patients reported significantly impaired QOL on nine of 15 scales/items (p<0.01) relative to the general population. Fatigue, loss of appetite, and impaired sense of well-being were the most troublesome symptoms on the ESAS, measured to 4.4(+/-2.8)/5.3(+/-2.3), 4.4(+/-3.2)/5.9(+/-2.7), and 4.0(+/-2.9)/4.6(+/-2.7) (mean+/-SD) at baseline and 8 weeks before death, respectively. Forty-four of the 51 (86%) initial consultations and 107 (58%) of the 185 follow-ups (124 clinical and 61 phone-calls) resulted in palliative care interventions, most frequently changes in opioid or laxative medication and dietary advice. CONCLUSIONS: Patients with advanced pancreatic cancer develop several distressing symptoms. ESAS was useful for assessment of symptom prevalence and intensity and is a clinically adequate method for symptom control. A multidisciplinary approach is necessary for the best palliation of symptoms at the time of diagnosis and during follow-up.

Nonoperative management of splenic injuries: improved results with angioembolization.

BACKGROUND: Nonoperative management (NOM) of patients with severe splenic injuries carries a significant risk of failure. We hypothesized that adding angiographic embolization (AE) to the NOM protocol would decrease the laparotomy rate, and increase the success rate of NOM and splenic salvage rate. METHODS: A protocol introducing AE in the treatment of splenic injuries was implemented. AE was performed in OIS splenic injury grades 3 to 5 and in all cases where signs of ongoing bleeding were encountered regardless of injury grade. Patients included in a prospective study during a 24-month period were compared with a historic control group. RESULTS: Group 1 (before AE) consisted of 69 patients with a mean Injury Severity Score (ISS) of 31, and group 2 (after introducing AE) included 64 patients with a mean ISS of 30. In group 1, 30 patients underwent immediate laparotomy (43%), and the NOM success rate was 79%. After introducing AE, 17 patients underwent immediate laparotomy (27%; p = 0.04), with a NOM success rate of 96% (p = 0.02). Overall splenic salvage rate increased from 57% to 75% (p = 0.02). Angiography was performed in 31 patients in group 2. Embolization was performed in 27 of these patients. AE failure rate was 4%. NOM was successful in 14 of 15 patients with OIS injury grades 4 and 5 after the introduction of AE (93%). CONCLUSION: A formal protocol adding mandatory AE to NOM for severe splenic injuries increased the percentage of patients in whom NOM was attempted, the NOM success rate, and the splenic salvage rate.

The impact of patient volume on surgical trauma training in a Scandinavian trauma centre.

OBJECTIVE: Some of the problems faced in trauma surgery are increasing non-operative management of abdominal injuries, decreasing work hours and increasing sub-specialisation. We wanted to document the experience of trauma team leaders at the largest trauma centre in Norway, hypothesising that the patient volume would be inadequate to secure optimal trauma care. METHODS: Patients registered in the hospital based Trauma Registry during the 2-year period from 1 August 2000 to 31 July 2002 were included. RESULTS: Of a total of 1667 patients registered, 645 patients (39%) had an Injury Severity Score (ISS)>15. Abdominal injuries were diagnosed in 205 patients with a median ISS of 30. An average trauma team leader assessed a total of 119 trauma cases a year (46 patients with ISS>15) and participated in 10 trauma laparotomies. CONCLUSION: Although the total number of trauma cases seems adequate, the experience of the trauma team leaders with challenging abdominal injuries is limited. With increasing sub-specialisation and general surgery vanishing, fewer surgical specialties provide operative competence in dealing with complicated torso trauma. A system of additional education and quality assurance measures is a prerequisite of high quality, and has consequently been introduced in our institution.

Advanced surgical trauma care training with a live porcine model.

OBJECTIVE: To evaluate the benefit of a compulsory operative trauma care course for general surgeons in Norway utilising a live porcine model. METHODS: The participants rated their expertise in 23 situations pre- and post-session on a scale 1-5, where 1 meant "not competent" and 5 meant "fully competent". RESULTS: Mean total score increased 43% from pre- to post-session. The increase reached significance with all levels of experience. Procedures rarely performed, like suturing on a beating heart, showed a greater educational benefit than more frequently performed procedures, like inserting a chest tube. CONCLUSION: The operative trauma care animal session increased the participants' perceived competence significantly. Its use seems justified for education in trauma related lifesaving surgical procedures.

[Vacuum pack technique--a good method for temporal abdominal closure].

UNLABELLED: Abdominal compartment syndrome(ACS) is a clinical entity characterised by increased intraabdominal pressure leading to multiple organ failure, fatal if left untreated. The treatment of abdominal compartment syndrome is surgical decompression with a temporary abdominal wall substitute. To avoid the development of abdominal compartment syndrome, temporary abdominal closure (TAC) should be considered after celiotomy for trauma. A new method for TAC was introduced at Ullevaal University Hospital in 2002, the "vac pac". METHOD: The "vac pac" technique is described and the patients treated with "vac pac" during the first year after introduction are presented. RESULTS: Five patients were treated using the "vac pac". One patient had acute pancreatitis and developed abdominal compartment syndrome. The other patients were severely injured and the indication for TAC was abdominal compartment syndrome in one patient, intestinal oedema in another, and damage control surgery with packing in two patients. Delayed primary closure was achieved within five days in all our patients. There were no fatalities and no complications related to the use of "vac pac" were registered. CONCLUSION: The "vac pac" technique seems to be a good method for TAC.

[Outpatient laparoscopic fundoplication for gastroesophageal reflux disease].

BACKGROUND: Day-case laparoscopic fundoplication for gastro-oesophageal reflux disease was introduced in January 1997. MATERIAL AND METHODS: Inclusion criteria were ASA grade 1-2, living within 30 minutes by car from the hospital, or staying over in the patient hotel the first night, with company. Initially, only selected patients were offered day-case treatment; later it was adopted as routine. The patients underwent general intravenous anaesthesia with propofol and remifentanil and were given prophylaxis against postoperative pain and nausea. The surgical procedure was Nissen-Rossetti fundoplication or semifundoplication. RESULTS: 83 patients were included. Ten patients were admitted, 73 (88%) were discharged as planned 3-8 hours after the operation. Eight patients (10%) were readmitted; one of them underwent reoperation for necrosis of the gastric fundus. Eight patients visited the outpatient department without need for readmission. At seven-day follow-up, 55 discharged patients (75%) were satisfied with the day-case treatment, nine (12%) were indifferent, and nine (12%) were dissatisfied, mostly because of pain. If offered a similar operation in the future, 50 patients (68%) would have preferred and 11 (15%) would have accepted day-case treatment; 12 (16%) would not. INTERPRETATION: Outpatient laparoscopic fundoplication is safe and well tolerated by the majority of patients.

[Laparoscopic fundoplication for gastroesophageal reflux disease].

BACKGROUND: In 1995 we introduced laparoscopic technique as routine for fundoplication for gastro-esophageal reflux disease. MATERIAL AND METHODS: 222 patients were scheduled for laparoscopic fundoplication; the operation was completed laparoscopically in 219 patients. They all had an observation period of one year as a minimum; 205 patients returned a follow-up questionnaire. RESULTS: 12 patients had major complications, six of them have been reoperated. At follow-up, 95% reported excellent or good results, 3% had persisting reflux symptoms, 4% had moderate to severe dysphagia and 17% had moderate to severe gas bloat syndrome and flatulence problems which adversely affected an otherwise good outcome. Thus, 63% reported excellent, 23% good and 7% fair outcome, and 6% were moderately or very dissatisfied. Bloating and increased flatulence were the major reasons for dissatisfaction. INTERPRETATION: The risk of troublesome postoperative bloating and flatulence should be addressed thoroughly during the preoperative information, and especially in patients who have similar symptoms preoperatively.

[Laparoscopic treatment of splenic cysts].

Splenic cysts are uncommon. The symptoms are usually vague, but complications such as haemorrhage, rupture and infection may occur. The majority of splenic cysts are seen in children and young adults. Surgical treatment is recommended and splenic preservation is advantageous. We present two patients with splenic cysts successfully treated with laparoscopic resection of the cyst wall.

[Secretin stimulated magnetic resonance cholangiopancreatography in diseases of the biliary and pancreatic ducts].

BACKGROUND: MRCP has replaced ERCP as the diagnostic tool in diseases in the biliary and pancreatic ducts. Secretin increases the secretion to ducts, and this has been reported to improve MRCP image quality. MATERIAL AND METHODS: We report our experience with S-MRCP in our first 20 patients. Secretin was given intravenously and images were obtained every minute for 10 minutes. These images were compared with MRCP images taken before and after secretin stimulation. RESULTS: New information was yielded in 18 cases, i.e. information not observed in previous radiological examinations. INTERPRETATION: In diagnostics of dysfunction of the sphincter of Oddi, the method may be useful, given the functional aspect of the procedure where increased pressure in the ducts may lead to pain. It may further improve the diagnostics of pancreatic cancer versus pancreatitis, in pancreas divisum and sclerosing cholangitis. The method is also valuable for clarifying whether there is injury to the pancreatic duct after blunt abdominal trauma. Surgical common bile duct injuries may be better assessed than with any other method. In difficult pancreatic and biliary investigations, S-MRCP seems to be a useful and complication-free supplement to existing diagnostic methods.

From operating theatre to operating studio--visualizing surgery in the age of telemedicine.

We have conducted a telemedicine project between two of Norway's largest hospitals (Rikshospitalet and Ullevål Hospital) with a focus on image-guided surgical and radiological procedures. Video was broadcast using a 34 Mbit/s ATM network. This resulted in changes in the local work practice to accommodate and facilitate the communication. It also required changes to the surgeon's tasks to improve communication with remote viewers. These changes were not trivial and can be viewed as signs of a shift towards a more public kind of surgery and interventional radiology, brought about by new technology.
