Survey of methods of treatment of haemorrhoids and complications of injection sclerotherapy.

INTRODUCTION: This study was conducted to survey current practices in the treatment of haemorrhoids (Hs), prevalence of complications associated with injection sclerotherapy (IS) and attitudes to its use to treat anterior Hs. METHODS: Postal questionnaires were sent to 92 consultant surgeons in the South East Thames Region. They were returned anonymously. RESULTS: Seventy questionnaires were returned (76% response rate) and 61 questionnaires were used in the data analysis; 18 from coloproctologists and 43 from non-coloproctologists who treated Hs. First degree Hs were mostly treated with IS alone (76%). Second degree Hs were treated with rubber band ligation (RBL) alone (36%) or a combination of IS and RBL (36%). Third degree Hs were mostly treated with haemorrhoidectomy (76%). Nineteen surgeons (31%) reported complications using IS; 82% of these were urological. Nine surgeons (15%) did not use IS to treat anterior Hs and 10 (16%) advised their trainees not to inject anteriorly. CONCLUSIONS: IS is a common treatment of Hs. Nearly one-third of consultants reported complications, the majority of which were urological and likely to be secondary to IS of anterior Hs. It may be safer to avoid IS of anterior haemorrhoids.

Consistency of teaching in parallel surgical firms: an audit of student experience at one medical school.

BACKGROUND: Traditional clinical clerkships have been based on the apprenticeship model of learning, with opportunistic teaching by doctors on presenting patients. Students at King's College School of Medicine, London had expressed concern that they were receiving inequitable experiences in different clerkships. This had become more apparent since the introduction of a school-wide end-of-year skills assessment. We decided to assess the consistency of delivery of the surgical syllabus. METHOD: A multistage questionnaire survey was undertaken with third-year (first clinical year) undergraduate medical students on surgical clerkships. The questionnaire required students to record topics about which they had been taught, and practical skills on which they had been supervised, from the surgical syllabus pertaining at the time. RESULTS: 194 (46.4%) questionnaires were returned. A low level of consistency was reported in the teaching of theoretical topics and practical skills across surgical clerkships in eight different locations. There were substantial differences, both in overall coverage of the syllabus and in the priority given to different topics. There were no overall differences between teaching hospital- and district general hospital-based clerkships. DISCUSSION: Students in so called 'parallel' clerkships did not receive comparable teaching. The traditional opportunistic nature of clinical teaching led, in effect, to individual curricula within each clerkship. The General Medical Council has called for a core curriculum to be delivered across different clinical sites within each medical school. To achieve this, medical schools may need to introduce guidelines to direct teaching in the same way that clinical protocols have been developed to achieve greater standardization in clinical practice.

Smoking may be associated with complications in diverticular disease.

BACKGROUND: The vast majority of people with diverticula remain asymptomatic or develop minor symptoms while a small group develop serious complications that are associated with significant morbidity and mortality rates. The aim was to identify any risk factors predisposing to complications. METHODS: Eighty patients with diverticular disease were studied. Patients in group 1 (n = 45) with complications requiring hospitalization or surgery were compared with those in group 2 (n = 35) with asymptomatic diverticula or minor symptoms. Logistic regression analysis was performed. RESULTS: No differences in epidemiological factors, concurrent and past medical and surgical conditions or chronic medication were detected between the two groups. Generalized disease was not associated with more complications than sigmoid disease. However, smoking seemed to be an independent factor predisposing to complications; the proportion of smokers in group 1 was significantly greater (24 of 45) than that in group 2 (ten of 35) (odds ratio 2.9, P = 0.028). CONCLUSION: In patients with diverticular disease, smoking is associated with an increased risk of complications.

Lymphogranuloma venereum as a cause of rectal strictures.

Rectal strictures are uncommon in young patients without a history of malignancy, inflammatory bowel disease or previous surgery. Lymphogranuloma venereum of the rectum has been described as a rare cause of rectal strictures in the western world, mainly in homosexual men and in blacks. It presents with nonspecific symptoms, rectal ulcer, proctitis, anal fissures, abscesses and rectal strictures. Clinical and endoscopic findings as well as histology resemble Crohn's disease, which may be misdiagnosed. Serology is often positive for Chlamydia trachomatis but negative serology is not uncommon. We present two young black women who suffered from chronic diarrhoea, abdominal pain and weight loss. There was no previous history and investigations showed in both cases a long rectal stricture. Serology was positive in one patient. They were treated with erythromycin and azithromycin and they both underwent an anterior resection of the rectum. Postoperative histology confirmed the presence of lymphogranuloma venereum of the rectum. We conclude that rectal lymphogranuloma venereum is a rare cause of rectal strictures but surgeons should be aware of its existence and include it in the differential diagnosis of unexplained strictures in high-risk patients.

Predicting changes in the distribution of sweating following thoracoscopic sympathectomy.

BACKGROUND: Compensatory sweating is a common symptom following thoracic sympathectomy; however, the reported incidence of this complication varies greatly, and its severity has not been quantified. METHODS: In this study changes in the distribution of sweating following bilateral T2-3 thoracoscopic sympathectomy for hyperhidrosis were assessed in 42 patients. Sweat production in the palms, axillae, face, trunk and feet was assessed using a linear analogue scale. RESULTS: The operation was most successful in reducing sweat production in the palms, axillae and face (in descending order). The operation also reduced pedal sweat production in 12 of the 29 patients who suffered concomitant pedal hyperhidrosis. Compensatory truncal sweating occurred in 36 of the 42 patients; it was severe in ten, moderate in 16 and minimal in ten. CONCLUSION: Patients should be warned about compensatory sweating before thoracic sympathectomy.

Emergency surgery in Ethiopia.

The surgical needs of Ethiopia are not met by traditionally trained surgeons. Ten recently registered doctors were trained for a two-month period in 20 selected lifesaving procedures. Evaluation of their skills one year after their course suggested that they were able to save lives and to use their skills either under supervision or alone. The training of physicians before their appointment to rural areas is a possible solution to the unacceptably high morbidity and mortality from surgical causes in rural Ethiopia.

One lung ventilation in endoscopic transthoracic sympathectomy.

Endoscopic transthoracic sympathectomy currently requires one lung anaesthesia to facilitate access to the thoracic sympathetic chain. This may cause reduced perioperative arterial oxygen saturation. We describe a series of patients in which the collapsed lung is kept partially inflated using continuous positive airway pressure (CPAP) with 100% oxygen. This modification of anaesthetic technique enabled a normal arterial oxygen saturation to be maintained thus preventing operative delays whilst the lung was reinflated to restore adequate oxygen saturation.

A novel means of securing a laparoscopic port in the obese patient.

Advanced interventional laparoscopy has necessitated the development of a vast array of new equipment, but inevitably some of this equipment has had to be adapted to specific patient needs. Standard laparoscopic ports may be too short for use in obese patients. We describe a technique using a Portex endotracheal tube as an over-tube, which will overcome this problem.

Endoscopic transthoracic sympathectomy for idiopathic upper limb hyperhidrosis.

A 5-year experience of 51 endoscopic transthoracic dorsal sympathectomies for idiopathic palmar hyperhidrosis in 26 patients is presented. Fifty-two percent complained of excessive sweating over their hands, 28% of axillary sweating and 20% over both areas, with a mean duration of 10 years. The second, third and fourth thoracic ganglia and their interconnecting fibres on the affected side were ablated using diathermy cautery. Over a mean follow up time of 26 months, this procedure was successful in curing or improving intractable sweating in 92%. However, axillary sweating was less well controlled than in the palms with 20% of patients describing residual wetness in the axilla. Compensatory sweating (75%) and gustatory sweating (48%) were the commonest side effects; despite this, most patients were satisfied with the functional and cosmetic outcome. Other complications included a temporary Horner's syndrome in one patient, a pneumothorax in the immediate post-operative period in another and a unilateral non-infective reactionary pleural effusion in a third. Two patients developed recurrence of palmar hyperhidrosis within 6 months of surgery. One has been successfully treated by re-operation on the affected side. All patients complained of mild to moderate interscapular chest pain which was easily controlled by non-steroidal anti-inflammatory agents, and resolved within 7-10 days post-operatively. The technique of endoscope transthoracic sympathectomy is effective, relatively simple to perform and usually requires only an overnight stay. It is recommended as the surgical treatment of choice for upper limb hyperhidrosis unresponsive to conservative measures.

Pseudosepsis in rheumatoid arthritis due to cellular and lipid abnormalities in synovial fluid.

In acute septic arthritis, the synovial fluid is usually frankly purulent. However, the presence of pus does not always imply the presence of infection, and some synovial fluids are easily mistaken for pus. An exaggeration of the normal leucocyte response in inflammatory joint fluids may alone simulate sepsis; marked increases in certain lipid fractions of the fluid may produce similar appearances. We describe a patient who presented with two examples of such 'pseudoseptic arthritis'.

Endoscopic transthoracic sympathectomy in the treatment of hyperhidrosis.

A 5-year experience of 50 endoscopic transaxillary dorsal sympathectomies is presented. The procedure was successful in either curing or improving the symptoms of hyperhidrosis in the great majority of patients. The commonest side effects were compensatory sweating (75%) and gustatory sweating (48%); despite this, there was an extremely high level of patient satisfaction. Permanent Horner's syndrome did not occur. The procedure is effective, simple, cheap, and requires only an overnight stay; and is recommended as the method of choice for the surgical treatment of upper limb hyperhidrosis.

Pyoderma faciale in a patient with Crohn's disease.

We wish to report the progress of a patient with pyoderma faciale and Crohn's disease. The patient is interesting in that on two occasions the relapse in her skin condition coincided with the introduction of non-steroidal anti-inflammatory drugs. Therapy with isotretinoin was effective and well tolerated.
