Aspirates (n = 163) from 157 patients with enlarged superficial lymph nodes were obtained over a 5-year period in a combined surgical/FNAC clinic. A definitive diagnosis was achieved in over 77% of the cases: benign 52.7%, malignant 25.1%. The diagnostic accuracy was 94.4%, sensitivity 85.4%, and specificity 100%. The false-negative rate was 12.5% but decreased to 3.5% when lymphoma cases were excluded. There were 36 cases of metastatic disease, the majority of which were from a primary breast carcinoma. The main diagnostic difficulty was in distinguishing low-grade lymphoma from reactive hyperplasia. An added advantage was that aspirated material could be used in ancillary tests to help with the differential diagnosis. FNAC has a well-defined role in the investigation of superficial lymphadenopathy. Used in the proper setting it will provide a definitive diagnosis in the majority of cases, especially relating to recurrent malignancy or metastatic disease. Patients with a reactive cytological picture and no clinically suspicious symptoms could be spared unnecessary surgery and reviewed through follow up. This technique is cost-effective, of high diagnostic accuracy, and results in considerable resource savings.

One hundred and thirty seven previously untreated outpatients with first and second degree haemorrhoids were allocated at random to treatment by infrared coagulation (n=66) or rubber band ligation (n= 71). Complete follow up was obtained in 122 patients (60 who had undergone infrared coagulation (group 1), and 62 rubber band ligation (group 2)) at periods from three months to one year after completion of treatment.Infrared coagulation produced a satisfactory outcome in 51 patients (85%): 34 were rendered asymptomatic and 17 improved. Rubber band ligation produced a satisfactory outcome in 57 patients (92%): 33 were rendered asymptomatic and 24 improved. Both methods were equally effective in first and second degree haemorrhoids. The incidence of side effects, particularly discomfort, during and after treatment was significantly higher in those treated by rubber band ligation (p <0 001). This appeared to be an appreciable deterrent to future patient compliance. The number of patients losing more than 24 hours from work was higher after rubber band ligation than after infrared coagulation. The number of treatments necessary to cure symptoms did not differ significantly between the two methods. Infrared coagulation

Background: Inguinal hernia repair is a common low-risk intervention. Patient-reported outcomes (PROs) are being used increasingly as primary outcomes in clinical trials. The aim of this study was to review and meta-analyse the PROs in RCTs comparing laparoscopic versus open inguinal hernia repair techniques in adult patients.Methods: A systematic review and meta-analysis was carried out in accordance with PRISMA guidelines. Only RCTs in peer-reviewed journals were considered. PubMed, Ovid Embase, Scopus and the Cochrane Library were searched. In addition, four trial registries were searched. The search interval was between 1 January 1998 and 1 May 2018. Identified publications were reviewed independently by two authors. The review was registered in the PROSPERO database (CRD42018099552). Bias was assessed using the Cochrane Collaboration risk-of-bias tool.Results: Some 7192 records were identified, from which 58 unique RCTs were selected. Laparoscopic hernia repair was associated with significantly less postoperative pain in three intervals: from 2 weeks to within 6 months after surgery (risk ratio (RR) 0⋅74, 95 per cent c.i. 0⋅62 to 0⋅88), 6 months to 1 year (RR 0⋅74, 0⋅59 to 0⋅93) and 1 year onwards (RR 0⋅62, 0⋅47 to 0⋅82). Paraesthesia (RR 0⋅27, 0⋅18 to 0⋅40) and patient-reported satisfaction (RR 0⋅91, 0⋅85 to 0⋅98) were also significantly better in the laparoscopic repair group. Conclusion:The data and analysis reported in this study reflect the most up-to-date evidence available for the surgeon to counsel patients. It was constrained by heterogeneity of reporting for several outcomes. Summary measures and synthesis of resultsPROs are shown as crude rates and, if appropriate, mean scores. Meta-analysisMeta-analysis was undertaken for each distinct outcome if there were two or more RCTs that examined the same

Background: Cystic neoplasms of the pancreas contribute to 10–20% of pancreatic tumours. Malignant cystic tumours of the pancreas behave similar to adenocarcinomas and thus warrant aggressive management. However, certain benign cystic neoplasms do not require operative intervention. It is, therefore, important to differentiate benign lesions from malignant lesions and from those with malignant potential. Aims: To provide an overview of the role of radiological investigations in the management of cystic neoplasms of the pancreas, with emphasis on the characteristic features of aggressive tumours. The role of different imaging modalities is discussed, and an investigative algorithm suggested. Methods: A literature review was carried out on Medline, Cochrane library, and PubMed using the MeSH terms ‘pancreas’ and ‘cysts’ to source relevant papers. Search criteria were limited to English literature, meta-analyses, systematic reviews, prospective and retrospective case series, published during or after 1998. Discussion: Each pancreatic cystic lesion has characteristic radiological findings. However, the diagnostic accuracy of individual imaging techniques is still limited. A combination of imaging modalities is essential for preoperative diagnosis. CT complemented by endoscopic ultrasound and cyst fluid analysis appears to be the most promising investigation in diagnosing cystic neoplasms. Follow-up with serial imaging is useful for lesions of uncertain aetiology.
