Surgery for chronic pancreatitis: a review of 12 years experience.

The surgical management of chronic pancreatitis remains controversial. We have practised a selective approach to surgery using symptoms and endoscopic retrograde cholangiopancreatography (ERCP) as the indications for operation and the procedure performed. A total of 76 patients who underwent surgery for chronic pancreatitis over a 12 year period were reviewed. Of the patients, 24 (32%) had a Whipple's resection (WR), 41 (54%) distal pancreatectomy (DP) with drainage, and 11 (14%) had other procedures. Eleven patients had died. Hospital records were reviewed and of the 65 patients alive at follow-up, 51 (79%) were interviewed. Twenty-three patients (74%) who underwent DP reported either excellent or good general health compared with 7 (44%) who had WR (P = 0.04). However, there was no difference in general health between operative groups using visual analogue scales. There was no difference in pain at follow-up between DP and WR. Of patients interviewed, 88% felt that their pain was better than before operation and 25 (49%) had no pain at all. Diabetes developed more frequently after DP (P = 0.005) than after WR. Good results can be achieved by pancreatic resection when careful selection is exercised.

Audit of the outcome of peptic ulcer disease diagnosed 10 to 20 years previously.

UNLABELLED: METHODS/AIMS: During 1993-1994 an audit of the outcomes of a consecutive series of peptic ulcer patients, first diagnosed endoscopically between 1972-1983, was carried out. Three hundred and thirty six patients fitting the entry criteria were identified, 46 had died in the interval, and 44 were lost to follow up, leaving 246 available for evaluation. All patients completed questionnaires on their current symptomatic state, drug treatment, and details of any operations they had undergone since their original diagnosis. In addition they were asked to indicate, on an analogue scale, their overall assessment of how their ulcer problem was affecting them at the time of the review. Where available hospital records were obtained and analysed for any further admissions and the results of any further endoscopies. RESULTS: Of the 246 patients, 158 were men and 88 female. Duodenal ulcers (DU) were present in 204 and gastric ulcers (GU) in 51 (nine had both a DU and GU). Since the diagnosis 65 patients had undergone surgical treatment: 44 for poor ulcer control, nine for pyloric stenosis, nine for a perforation, one for a major gastrointestinal bleed, and two for a gastric carcinoma developing within two years of the diagnosis of a GU. The overall incidence of ulcer complications during this follow up period (excluding the carcinomas) was 7.7%. Initial medical treatment was with histamine H2 blockade in 234 patients--87.4% cimetidine (C) and 11% ranitidine (R)--with other agents in the remainder. At follow up 176 patients were still receiving medical treatment (C, 71%: R, 22%, other, 7%) including 30 who had previously undergone a definitive surgical procedure. Dyspeptic symptoms were recorded in 50.4% of the patients, abdominal pain being the commonest complaint. There was a significant relation between abdominal pain and the analogue scores provided by the patients with significantly more (p = 0.02) of those who had undergone surgical treatment recording this as a continuing problem (44.6% v 36%). CONCLUSION: There is no evidence provided by this study that, in these patients, their ulcer disease is undergoing spontaneous remission with time.

The clinical terms project: its potential for computerised surgical audit.

Computerised surgical audit requires accurate and detailed clinical information on individual patients. This requires a standardised language which can be understood and used by both clinicians and computers. The present system of classifying patients using OPCS and ICD coding systems does not allow this because both are awkward and imprecise. The clinical terms project was set up to overcome these problems. Its aim was to develop a complete medical thesaurus of terms which medical and paramedical disciplines could use in their own practice. To audit activities in general surgery one needs to be able to record diagnostic information, operative procedures, investigations, therapeutic actions, non-operative procedures, etc. Such information needs to be recorded with various levels of detail depending on the degree of specialisation of the surgeon involved (eg, a general versus a highly specialised surgeon). In addition data needs to be cross-mapped to national classification systems (ICD, OPCS). To provide the level of clinical detail required it has been found necessary to separate terms into a 'main core term' and 'qualifying terms'. This has resulted in a shorter but more comprehensive thesaurus of clinical terms which will enable rapid and consistent data transfer between different computer systems.

Comparison of short term outcomes of open and laparoscopic cholecystectomy.

OBJECTIVE: To compare the three month outcome of open and laparoscopic cholecystectomy. DESIGN: Prospective assessment of outcome for a series of patients encompassing the introduction of the laparoscopic technique. SETTING: One teaching hospital. PATIENTS: 269 patients admitted for open cholecystectomy between January 1989 and March 1992 and 122 admitted for laparoscopic cholecystectomy between January 1991 and March 1992. MAIN MEASURES: Patients' reported symptoms and self assessed scores with the Nottingham health profile before operation and at three month follow up. Incidence of complications and adverse events after discharge. RESULTS: Similar improvements in symptom rates and health scores were seen regardless of surgical technique. A lower rate of postoperative complications was seen in the patients given laparoscopic surgery (6/95(6%) v 45/235(19%)), and their mean length of stay was lower (4.5 v 9.8 days). Similar results were obtained when the analysis was restricted to a subset of fairly uncomplicated cases (patients aged 60 or less without other illnesses on admission who were not undergoing emergency or urgent surgery), which constituted a larger proportion of the group given laparoscopy (35/95(37%) v 40/235(17%)). Between these two groups no significant difference was seen in the frequency of relevant readmissions to hospital or visits to general practitioners or accident and emergency departments. CONCLUSION: Ideally, a new surgical technique would be evaluated in a randomised trial. In the absence of such a trial, this observational study provides some evidence that the switch from open to laparoscopic cholecystectomy has brought benefits, particularly in terms of reduced length of stay in hospital. A range of clinical and patient derived indicators suggests that these gains have not been associated with a reduction in the quality of the outcome at three months.

Role of endoscopic retrograde cholangiopancreatography in the investigation of pain after cholecystectomy.

Patients who continue to have or who develop abdominal pain after apparently successful cholecystectomy pose diagnostic difficulties. This study reports 384 such patients, investigated by endoscopic retrograde cholangiopancreatography (ERCP). There were 146 patients with abdominal pain alone with no previous history of common bile duct (CBD) exploration, of whom only 17 (11.6 per cent) had CBD stones on ERCP. Bile duct calculi were present in 76 of 140 patients (54.3 per cent) with abnormal biochemical findings (raised alkaline phosphatase and/or amylase level) and in 34 of 57 (60 per cent) with an abnormality detected on ultrasonography or intravenous cholangiography. A combination of biochemical and radiological abnormalities was present in 37 patients and was associated with CBD stones in 28 (76 per cent). Patients who had undergone CBD exploration represented a special group, of whom the majority (75 per cent) had common duct stones at ERCP even in the absence of biochemical and radiological abnormalities. ERCP is a useful investigation in patients with persistent postcholecystectomy symptoms. Other features in addition to pain or a history of CBD exploration may be relevant to the decision to perform ERCP in the investigation of these patients.

Treatment of common bile duct stones using mono-octanoin.

A retrospective analysis of 48 patients undergoing mono-octanoin infusion via nasobiliary catheter following failure of endoscopic extraction of common bile duct stones is reported. Among 35 patients who received a complete course of treatment, nine (26 per cent) had duct clearance by the completion of the infusion and a further eight on subsequent endoscopic retrograde cholangiopancreatography (ERCP) (total 49 per cent). Two patients had a successful stone extraction after enlargement of the sphincterotomy (total non-surgical clearance rate 54 per cent). None of five patients with stones greater than 2 cm in diameter had stone clearance at the completion of the infusion and only one at subsequent ERCP. Among 13 patients receiving an incomplete course of treatment seven had clear ducts on repeat ERCP (54 per cent). Mono-octanoin infusion via a nasobiliary catheter is of limited value in the management of this difficult group of patients, although it may be successful in some.

Sampling time for serum gentamicin levels.

A survey in 53 UK hospitals showed that 44% of clinical microbiologists recommended post-dose serum gentamicin concentrations to be measured at less than 40 min after an iv bolus dose. Serum gentamicin concentrations were measured in ten patients following bolus iv and im injections. Distribution of the drug occurred for up to 45 min following iv doses and maximum serum concentrations occurred at 45 to 60 min after im injection. The data validate current guidelines to sample at 60 min post bolus iv and im doses. Earlier sampling after iv bolus injections may result in significantly higher gentamicin concentrations, leading to potential interpretive errors of clinical significance.

Evidence for validity of a health status measure in assessing short term outcomes of cholecystectomy.

OBJECTIVE: To assess the validity of the Nottingham health profile (NHP) as an indicator of short term outcome of cholecystectomy. DESIGN: Prospective assessment of outcome. SETTING: One teaching hospital. Patients--161 consecutive patients admitted for cholecystectomy between January 1989 and September 1990. MAIN MEASURES: Patients' reported symptoms and self assessed NHP scores before cholecystectomy and at follow up at three and 12 months (76 patients); assessment before admission (19). RESULTS: Complete data were obtained preoperatively and at three months' follow up from 154 patients; seven did not respond to the follow up questionnaire. 76/84(90%) patients in the study 12 months or more answered the 12 month follow up questionnaire; eight did not respond. Significant changes in score before and at three months after the operation were observed for four of the six dimensions: energy (35.34 v 19.53, p < 0.0001), pain (27.38 v 9.8, p < 0.0001), sleep (26.99 v 17.51, p = 0.0002), and emotional reactions (16.12 v 7.56, p = 0.001). The mean scores for 76 patients followed up at three and 12 months showed little subsequent change. Scores in readmitted patients were all significantly higher, suggesting poor health. Patients with five reported symptoms had significantly worse scores for all dimensions. Scores were similar before cholecystectomy whether the questionnaire was completed before or after admission. CONCLUSION: The NHP is an appropriate tool for monitoring changes in health after cholecystectomy.

Medical therapy of Ménétrier's disease with omeprazole.

Medical therapy of Ménétrier's disease is often unsatisfactory and may lead to surgical treatment. Two cases, previously unresponsive to H2 antagonists, are presented showing a marked response to omeprazole.

Traumatic neuroma at the tail of the pancreas following splenectomy.

A 50 year old man presented with abdominal pain and weight loss after a splenectomy performed 26 years ago for abdominal trauma. At laparotomy, a mass was found at the tail of the pancreas. Pathological examination showed this was a traumatic neuroma and revealed evidence of chronic pancreatitis. Traumatic neuroma may be a rare cause of a pancreatic mass, especially after previous surgery or trauma.

Symptomatic gallstones--a disease of non-smokers?

Most patients with symptomatic gallstones undergo cholecystectomy. Since smoking may influence gallstone formation by depressing prostaglandin synthesis and mucus production in the gallbladder, we have examined smoking habits in a group of cholecystectomy patients. Two hundred and forty seven of 400 patients (62%) responded to a comprehensive postal questionnaire with 'buddy' controls of the same age and sex. Patients and controls did not differ significantly in their age, weight, past medical history, drug usage or alcohol consumption. Female patients had had a mean of 2.4 (SD 1.8) pregnancies, female controls 2.0 (SD 1.5; p less than 0.05, paired test). Analysis of smoking habits in 178 female patients showed 32% had smoked on average 18.4 cigarettes/day for a mean of 31 years whereas 52% of female controls had smoked 16.7 cigarettes/day for a mean of 37.0 years (p less than 0.001, McNemar's test for matched pairs). 39% of male patients smoked (21.7/day, 44.7 years) as compared to 61% of male controls (23.1/day, 46 years; p less than 0.01, McNemar's test). The influence of number of cigarettes smoked, sex and weight were investigated by using a logistic regression. This showed evidence of a linear relationship between amount smoked and risk of gallstones (chi 2 = 14.4, 1 d.f., p less than 0.001). There was no evidence that the effect of smoking differed with age or weight. Symptomatic gallstones is predominantly a disease of non-smokers.

The adherent gastric mucus gel barrier in man and changes in peptic ulceration.

The mucus barrier is a layer of water-insoluble gel adherent to the gastroduodenal epithelium. In man most previous studies have focused on luminal mucus or histological assessment of presecreted, intracellular mucus--neither of which can be directly correlated with the protective capacity of the adherent mucus barrier. We here describe direct observation of adherent mucus thickness in man, and changes in peptic ulceration. Adherent mucus gel on human antral mucosa is a continuous homogeneous layer of variable thickness, in the range 50-450 microns (median 180 microns), comprising 67% polymeric mucin. In gastric ulcer patients, adherent antral mucus is significantly increased in thickness (median 240 microns), but is very heterogeneous and structurally a substantially weaker gel, comprising only 35% polymeric mucin. Adherent antral mucus from duodenal ulcer patients is homogeneous, significantly thinner (median 110 microns), and structurally a weaker gel, comprising 50% polymeric mucin. The adherent mucus layer from patients with gastric carcinoma resembled that from subjects with gastric ulcer in that it was very heterogeneous, of significantly increased thickness (median 240 microns) and structurally a very weak gel (23% polymeric mucin). These results are discussed in the context of gastroduodenal mucosal protection against acid and pepsin in the gastric juice.

Pancreatic exocrine function after a sutureless pancreatico-jejunostomy following pancreaticoduodenectomy.

Exocrine pancreatic function was measured in 14 patients after pancreaticoduodenectomy for periampullary neoplasms in order to assess the patency of a sutureless pancreatico-enteric anastomosis. Pancreatic function was examined by the p-aminobenzoic acid/p-aminosalicylic acid (PABA/PAS) test 3-160 months after operation and compared with age- and sex-matched controls. There were no significant differences between mean (s.e.m.) serum PABA concentrations 3 h after ingestion of N-benzoyl-L-tyrosyl-PABA (25.5 (3.6)) mumol/l for patients, 26.1 (2.0) mumol/l for controls). However, the mean (s.e.m.) PABA excretion index was significantly lower in the patients (0.58 (0.08)) than in the controls (0.76 (0.04)). Four patients required pancreatic enzyme supplements for control of diarrhoea. Self-limiting pancreatic leaks occurred in two patients. The results suggests that the sutureless pancreatico-enteric anastomosis has an acceptably low leakage rate but that pancreatic exocrine function is diminished following pancreaticoduodenectomy with this technique. However, the majority of patients require no enzyme supplements and no significant tendency to late stenosis of the anastomosis was demonstrated.

In vitro study of human skeletal muscle strips: effect of nonesterified fatty acid supply on glucose storage.

To examine the effect of increased nonesterified fatty acid concentration on glucose storage in human muscle, an in vitro method for study of glycogen synthesis in this tissue has been established. Muscle strips obtained from rectus abdominus during elective abdominal surgery were clamped at resting length, and adenosine triphosphate/total adenosine nucleotide ratios remained constant for 3 hours ex vivo. Leakage of enzyme markers of muscle damage was minimal, and electron microscopy showed preserved myofibril ultrastructure. Insulin stimulation brought about a dose-dependent increase in rates of glycogen synthesis with a half-maximal effect at 9 x 10(-10) mol/L insulin. In 15 consecutive studies, basal rates of glycogen synthesis were 4.1 +/- 0.5, 3.2 +/- 0.7, and 3.0 +/- 0.3 nmol glucose/25 mg/h in the absence of palmitate, with 1.4 mmol/L and 2.8 mmol/L palmitate, respectively. Insulin-stimulated rates of glycogen synthesis were 8.6 +/- 1.2, 6.0 +/- 1.8, and 5.8 +/- 0.8 nmol glucose/25 mg/h. Thus, increasing fatty acid concentrations decreased rates of glycogen synthesis both basally and with insulin stimulation. The insulin signal itself was not affected as the percentage stimulation over basal rates remained approximately constant in the presence or absence of fatty acid (2.1-, 1.9- and 1.9-fold, respectively). Insulin sensitivity in vivo is usually expressed as absolute rates of glucose uptake during euglycemic hyperinsulinemia, and if plasma fatty acid elevation were to be studied in vivo an erroneous conclusion may be reached of resistance to hormone action per se.(ABSTRACT TRUNCATED AT 250 WORDS)
