Introduction: NICE has set standards for lymph node (LN) harvest in surgery for colorectal cancer (CRC). We report the effect of the operating surgeon and reporting pathologist on lymph node yield and the role of LN yield on survival. Method: Data on all patients with CRC treated in a single unit between 1999 and 2004 were collected in the ACPGBI database. Lymph node harvest was identified for each of three surgeons and three pathologists. Actuarial survival of all patients with Dukes’ stage B with greater than or less than 8 reported LNs and Dukes’ stage C were compared using log-rank test (Kaplan–Meier method). Results: A total of 380 cases had a curative resection with a unit median LN retrieval of 13. There was no difference in survival between Dukes’ stage B <8 LN (mean 42 months, 95% CI 29–55) and Dukes stage C (mean 45 months, 95% CI 29–51), log-rank P = 0.7618. Survival between Dukes stage B (8 LN and Dukes C was significantly different (mean 58 months, 95% CI 53–64 vs 45 months, 95% CI 29–51), log-rank P = 0.006. Conclusions: This study demonstrates that within a single unit the reporting pathologist significantly influences LN yield in CRC treatment and that a minimum of eight lymph nodes needs to be examined to stage CRC as Dukes’ C accurately. In this unit the surgeon was not a significant variable. [ABSTRACT FROM AUTHOR]

Introduction. The aim of this study was to examine the effect of surgeon relocation on lymph node (LN) retrieval in colorectal cancer (CRC) resection. Methods. The study population was 213 consecutive patients undergoing CRC resection by a single surgeon, at two units: unit one 110 operations (2002-2005) and unit two 103 (2005-2009). LN yields and case mix were compared. Results. Median LN harvests were significantly different between the two centres: unit 1: 13 nodes/patient and unit 2: 22 nodes/patient (P < .001). In unit one 42% of cases were LN positive and in unit two 48% (P = .398). There was no difference in case mix. Multivariate analysis identified unit (P < .001) and pathologist (P = .007) as independent predictors of harvest. Conclusions. A surgeon moving units can experience significantly different LN yield following CRC resection. Both units comply with national standards, but the "surgeon's results" at the two units appear to be pathologist dependent. This has implications for nodal harvest as a surrogate marker of surgical quality.

Introduction: Endoscopic retrograde cholangiopancreaticography (ERCP) is available in many district general hospitals in the UK. Most of the published literature on ERCP in cases with Billroth II gastrectomy reflects teaching hospital experience. The aim of this study was to evaluate this procedure in the district general hospital setting, over a 10-year period., Patients and Methods: Details of 41 consecutive patients, whom had previously undergone Billroth II gastrectomy and were referred for ERCP were analysed for presenting symptoms and outcome of their ERCP. All procedures were carried out by a single radiologist using a conventional Olympus side-viewing duodenoscope., Results: 48 examinations and 44 therapeutic procedures were carried out in 41 cases. Afferent loop intubation and cannulation of ampulla was successful in 87.5% and 98%, respectively. Two episodes of minor bleeding occurred after sphincterotomy, not requiring blood transfusion. One case of afferent loop perforation (2%) was repaired surgically. There were no cases of pancreatitis or death in this series., Discussion and Conclusions: The results show that ERCP after a Bilroth II gastrectomy can be safe and successful in the majority of cases when carried out by clinicians with a special interest, including those in a district general hospital However, experience with this procedure will diminish due to fewer indications for Billroth II gastrectomy and emergence of magnetic resonance cholangiopancreatography. It may be advisable to concentrate this technique in a few designated centres with skill and expertise.

Severe panniculitis caused by alpha1-antitrypsin deficiency is very rare even though the ZZ phenotype occurs in 1 : 3500 of the population of northern Europe. We describe a 33-year-old woman with rapidly progressing panniculitis and extensive skin necrosis with multiple life-threatening complications. Initial treatment followed by maintenance therapy with human purified enzyme (Prolastin, Bayer, Bridgend, U.K.) has been life-saving.

In a previous report the effectiveness of intraperitoneal bupivacaine in reducing pain following laparoscopic cholecystectomy was demonstrated. Other methods of pain relief are commonly used but none has been compared following laparoscopic cholecystectomy. In two further studies we have compared the analgesic effect of intraperitoneal bupivacaine against wound infiltration with bupivacaine, and against intraperitoneal bupivacaine with the addition of a non-steroidal anti-inflammatory drug (NSAID) in patients undergoing laparoscopic cholecystectomy. Two consecutive studies were performed. In the first, patients in group 1 were given 20 ml of 0.25% bupivacaine into the peritoneal cavity; patients in group 2 were given 20 ml of 0.25% bupivacaine injected into the trocar wounds. In the second study, patients in group 1 were given 20 ml of 0.25% bupivacaine into the peritoneal cavity; patients in group 2 were given 20 ml of 0.25% bupivacaine into the peritoneal cavity and a diclofenac suppository (100 mg) one hour before surgery. Postoperative pain was assessed with a visual analogue pain scale. There was no difference in pain scores in the two groups in either study. Intraperitoneal bupivacaine is as effective as wound infiltration. The addition of an NSAID makes no difference in the reduction of postoperative pain following laparoscopic cholecystectomy.

Consultant surgeons in two United Kingdom Health Regions were invited to complete a questionnaire on details of their personal management of patients with colon and rectal cancer, with particular emphasis on follow-up. Replies from 140 (94%) were analysed by the surgeon's subspecialty of colorectal and gastrointestinal surgery (group 1) and all others (group 2). There was a wide variation in the duration of followup, but no difference between the two groups. More group 1 surgeons carried out investigations as a routine after colonic (P < 0.01) and rectal (P < 0.01) resection. Colonoscopy was used more frequently by group 1 (P < 0.0001) and barium enema by group 2 surgeons (P < 0.05). Investigations to detect asymptomatic metastases were used as a routine by 33.3% of surgeons, in whom there was no concordance over the choice or combination of tests and no difference between the two groups of surgeons. There is no consensus among surgeons as to the ideal duration, intensity and method of follow-up after resection for colorectal cancer and little difference between the practice of colorectal and gastrointestinal surgeons and that of other specialists, except in the use of colonoscopy and barium enema. These results reflect the continuing lack of evidence on which to base the follow-up of patients after surgery for colorectal cancer.

The necessity of an outpatient (OP) consultation for patients referred for minor surgery under local anaesthetic (LA) was examined. Two separate prospective studies were performed. The first comprised 107 patients referred for minor surgery, who were assessed in the outpatient department (OPD), before being booked for minor operations. The second study comprised 106 patients whose names were placed directly on a minor operations list on the basis of the GP referral letter alone. In the first study, 97 (91 per cent) patients went on to undergo minor surgery. Five were not suitable for LA and in five an operation was considered unnecessary. Patients not suitable for LA included children, neck swellings, pre-auricular swellings and swellings described as lymph nodes. In the second study, the GP referral letters were screened to exclude the above and of 106 referrals 93 (88 per cent) underwent a minor operation. The benefit of the second study was twofold. First, 106 OP slots were available for other referrals and secondly, patients avoided the OP waiting list and did not lose time from work as a result of the OP visit. There were no adverse effects demonstrated during the second study. We believe the OP consultation can be avoided if the referral letters are carefully screened.

Laparoscopic cholecystectomy is now widely practised. There are various methods of pain relief used but none has been assessed or compared following this procedure. We have assessed the analgesic effect of intraperitoneal bupivacaine in laparoscopic cholecystectomy. Sixty consecutive patients were randomly assigned to one of two groups. Patients in group 1 were given 20 ml of saline injected under vision into the region of the gallbladder bed. Patients in group 2 were given 20 ml of 0.25% bupivacaine in a similar fashion. Postoperative pain was assessed with a visual analogue pain scale and the site of pain was recorded. Patients in the bupivacaine group had less pain in the early postoperative period and a lower incidence of pain in the right hypochondrium. Intraperitoneal bupivacaine is a simple and effective treatment for postoperative pain after laparoscopic cholecystectomy.

A unique case of somatostatinoma of the pancreas complicated by severe hypercalcaemia is described. Surgical resection was not possible owing to tumour extent. A dramatic and prolonged clinical and biochemical response was achieved with streptozotocin.

Esophageal varices in 57 consecutive children were treated by injection sclerotherapy using 5% ethanolamine oleate injection via a fiberoptic endoscope (Olympus P2). Variceal obliteration was achieved with 4.7 and 5.7 injections in the extra- and intrahepatic disease groups. Complications of injections included hemorrhage, esophageal ulceration, and stricture. Thirty two cases were followed from 6 to 60 months after treatment and only five further bleeds were observed (extrahepatic 1: intrahepatic 4). The early results suggest that sclerotherapy is an effective method for the control of esophageal varices in children.

In a prospective trial, the prophylactic efficacy of low-dose heparin was investigated in 84 consecutive patients undergoing total-hip replacement. 52 of these were randomly allocated to receive heparin or a combination of heparin and dihydroergotamine (D.H.E.); the remaining 32 patients, who were operated on by one orthopaedic team and did not receive prophylaxis, acted as a control group. The frequency of deep-vein thrombosis (D.V.T.), determined by the 125I-fibrinogen test and venography, was 69% in the control group, 32% in the patients receiving heparin alone, and 16% in those receiving heparin and D.H.E. The difference between the control group and each group receiving prophylaxis was statistically significant. The frequency of femoral-vein thrombi, demonstrated by venography, was analysed separately because of its frequent association with major pulmonary embolism. Femoral-vein thrombi developed in 17 (53%) in the control group, while they developed in only 4 patients (8%) in the prophylaxis group (P less than 0.01). 1 patient in the control group died due to massive pulmonary embolism; in another patient, again in the control group, clinical features suggestive of major non-fatal pulmonary embolism developed. This complication was not observed in patients receiving prophylaxis. There was no difference in the amount of operative or postoperative blood-loss in the three groups. In 3 patients in the entire series wound haematomata developed; all 3 were controls and haematomata developed after the administration of streptokinase or large doses of heparin for the treatment of extensive femoral-vein thrombi. By use of a sensitive assay, heparin could be detected in the plasma in 67% of samples in patients in whom D.V.T. did not develop. In contrast, in those patients in whom D.V.T. developed, heparin could be detected in only 21% of blood-samples (P less than 0.01). It is concluded that in patients undergoing total-hip replacement, low-dose heparin prophylaxis is effective in reducing the frequency of life-threatening extensive thrombi in the femoral vein. Prophylaxis using a combination of heparin and D.H.E. requires further evaluation.

Deep-vein thrombosis (D.V.T.) was detected by the fibrinogen-uptake test in six out of a total of thirty-one young women undergoing emergency abdominal surgery who gave a history of recent oral contraceptive intake. In contrast, no D.V.T. developed in nineteen similar patients who were not on oral contraceptives (P less than 0-01). Plasma-antithrombin-III activity was significantly lower preoperatively in patients taking oral contraceptives; postoperative D.V.T. subsequently developed in three out of five patients with preoperative antithrombin-III activity below 50%. In seventy-eight dental patients undergoing molar extraction, antithrombin-III activity was measured before, during, and after operation. Activity fell in all patients during operation, but the fall was significantly greater in women taking oral contraceptives (P less than 0-01). The intra-operative fall in antithrombin-III activity was prevented by a small preoperative dose of subcutaneous heparin.
