The appendix "mucocoele" misnomer: radiological terminology of "likely appendix mucinous neoplasm" better reflects pathology findings.

AIM: To review the radiological terminology used to describe dilated mucin-containing appendiceal lesions with correlation to the histopathological diagnosis. MATERIALS AND METHODS: Radiology and histopathology reports for all patients with an abnormally dilated appendix referred to a tertiary peritoneal malignancy centre, between January 2021 and December 2021, were reviewed. RESULTS: Overall, 213 patients were included with a median appendiceal diameter of 25.5 mm (range 10-125 mm). Peritoneal disease was present in 109 patients, with the remaining 104 cases demonstrating a dilated appendix only. Local radiology reports were available for 201 cases with the appendix described in 168 cases as appendiceal mucocoele (n=104), appendiceal neoplasm (n=40), appendicitis (n=18), and dilated appendix (n=6). The appendix was not mentioned in 33/201 (15%), either misinterpreted as other pathology (n=15) or not reported (n=18). Peritoneal malignancy histopathology reports were available in 188 cases and reported as low-grade appendix mucinous neoplasm (LAMN, n=144), high-grade appendix mucinous neoplasm (HAMN, n=13), LAMN with foci of HAMN (n=2), LAMN with neuroendocrine tumour (n=2), LAMN with goblet cell adenocarcinoma (n=1), goblet cell adenocarcinoma (n=8), mucinous adenocarcinoma (n=14), non-mucinous adenocarcinoma (n=1), and benign histology (n=3). Only one case of a true inflammatory "mucocoele"/retention cyst was reported. CONCLUSION: In this cohort of patients, the overwhelming majority of dilated, mucin-filled appendices contained malignant cells and benign mucin-filled appendices were rare. The present authors advocate that the term "likely appendix mucinous neoplasm" should replace "appendix mucocoele" to represent the most likely pathology and facilitate less ambiguous interpretation in management decisions.

Rectal Venous Malformation Treated by Superior Rectal Artery Embolization.

A 25-year-old female was referred to the Interventional Radiology Department for investigation and treatment of a rectal venous malformation (RVM) causing large recurrent episodes of rectal bleeding and chronic anaemia. Magnetic resonance imaging (MRI) demonstrated a large venous malformation affecting the rectum, lower pelvis and left thigh. After three failed attempts at injection foam sclerotherapy using fluoroscopic colonoscopy, a multidisciplinary team proposed an embolization procedure of the arterial inflow to the venous malformation. Following discussion with the patient, embolization of the superior rectal arteries was undertaken with immediate on-table fluoroscopic improvement in the RVM. Post-treatment, a significant reduction in bleeding, was reported by day 10 with subsequent return to activities of daily living and full employment. Follow-up MRI at 1 year demonstrated significant reduction in bowel-wall thickening.

Long-term outcomes of endovenous laser ablation and conventional surgery for great saphenous varicose veins.

BACKGROUND: Clinical guidelines recommend endovenous laser ablation (EVLA) over surgery based on short-term evidence, yet there are few studies reporting mid- to long-term outcomes. The aim of this study was to report the 5-year outcomes from an RCT of surgery versus EVLA for treatment of symptomatic great saphenous varicose veins. METHODS: Patients with symptomatic varicose veins due to great saphenous vein (GSV) incompetence were followed up 5 years after enrolment in a randomized trial of either surgery (saphenofemoral junction ligation, GSV strip to the knee and multiple avulsions of varicosities) or EVLA plus multiple avulsions. Outcomes included: clinical recurrence, defined as new varicose veins greater than 3 mm in diameter; Venous Clinical Severity Score (VCSS); quality of life measured by means of Short Form 36, EuroQol Five Dimensions (EQ-5D™) and Aberdeen Varicose Vein Questionnaire (AVVQ); patient satisfaction; and duplex ultrasound examination (DUS) findings. RESULTS: Some 218 of the 276 patients enrolled in the trial (79·0 per cent) were available for follow-up. Clinical recurrence was more frequent following surgery than EVLA at 5 years (34·3 versus 20·9 per cent; P = 0·010). Both groups demonstrated sustained significant improvements at 5 years over baseline in VCSS (surgery: median (i.q.r.) 1 (0-2) from 4 (3-5), P < 0·001; EVLA: 0 (0-1) from 4 (3-5), P < 0·001), AVVQ (surgery: 4·59 (0·56-9·78) from 13·69 (9·81-18·11), P < 0·001; EVLA: 3·35 (0·17 to 6·55) from 12·73 (9·41-17·32), P < 0·001) and EQ-5D™ (surgery: 1·000 (0·796-1·000) from 0·859 (0·796-1·000), P = 0·002; EVLA: 1·000 (0·796-1·000) from 0·808 (0·796-1·000), P = 0·002). VCSS was better for EVLA than surgery at 5 years (P = 0·031). Technical success assessed by DUS remained high at 5 years (85·4 per cent for surgery and 93·2 per cent for EVLA; P = 0·074). DUS-detected anatomical patterns of recurrence differed between the groups. CONCLUSION: EVLA was more effective than surgery in preventing clinical recurrence 5 years after treatment of great saphenous varicose veins. Patient-reported outcome measures were similar.

Compression regimes after endovenous ablation for superficial venous insufficiency--A survey of members of the Vascular Society of Great Britain and Ireland.

INTRODUCTION: The optimal compression regime following ultrasound guided foam sclerotherapy (UGFS), radiofrequency ablation (RFA) and endovenous laser ablation (EVLA) for varicose veins is not known. The aim of this study was to document current practice. METHODS: Postal questionnaire sent to 348 consultant members of the Vascular Society of Great Britain and Ireland. RESULTS: Valid replies were received from 41% (n = 141) surgeons representing at least 68 (61%) vascular units. UGFS was used by 74% surgeons, RFA by 70% and EVLA by 32%, but fewer patients received UGFS (median 30) annually, than endothermal treatment (median 50)--P = 0.019. All surgeons prescribed compression: following UGFS for median seven days (range two days to three months) and after endothermal ablation for 10 days (range two days to six weeks)--P = 0.298. Seven different combinations of bandages, pads and compression stockings were reported following UGFS and four after endothermal ablation. Some surgeons advised changing from bandages to stockings from five days (range 1­14) after UGFS. Following endothermal ablation, 71% used bandages only, followed by compression stockings after two days (range 1­14). The majority of surgeons (87%) also treated varicose tributaries: 65% used phlebectomy, the majority (65%) synchronously with endothermal ablation. Concordance of compression regimes between surgeons within vascular units was uncommon. Only seven units using UGFS and six units using endothermal ablation had consistent compression regimes. CONCLUSION: Compression regimes after treatments for varicose veins vary significantly: more evidence is needed to guide practice.

Systematic review of compression following treatment for varicose veins.

BACKGROUND: Consensus regarding compression following treatment of varicose veins has yet to be reached. This systematic review aims to establish the optimal compression regimen after venous treatment. METHODS: A systematic review of MEDLINE, Embase and CENTRAL was performed to identify randomized clinical trials (RCTs) investigating different compression strategies following treatment for superficial venous insufficiency. RESULTS: Seven RCTs comparing different durations and methods of compression fulfilled the inclusion criteria. The treatment modality was open surgery in three trials, foam sclerotherapy in two and endovenous laser ablation (EVLA) in two trials. The quality of the studies was variable, and significant sources of potential bias were present. Both the studies and compression regimens used were heterogeneous. Ten products were used in six general regimens for a duration of 0-42 days. One study suggested that 7 days rather than 2 days of stockings following EVLA was associated with superior quality of life and less pain at 1 week. Another study reported that, following surgery, application of a compression stocking after 3 days of bandaging was associated with a slightly longer recovery than no compression after 3 days. One study recorded compliance clearly, finding it to be only 40 per cent. The quality and heterogeneity of the studies precluded meta-analysis. CONCLUSION: There is currently little quality evidence upon which to base any recommendations concerning compression following treatment for varicose veins.

Clinical outcomes and quality of life 5 years after a randomized trial of concomitant or sequential phlebectomy following endovenous laser ablation for varicose veins.

BACKGROUND: Endovenous laser ablation (EVLA) is a popular treatment for superficial venous insufficiency. Debate continues regarding the optimal management of symptomatic varicose tributaries following ablation of the main saphenous trunk. This randomized trial compared the 5-year outcomes of endovenous laser therapy with ambulatory phlebectomy (EVLTAP) with concomitant ambulatory phlebectomy, and EVLA alone with sequential treatment if required following a delay of at least 6 weeks. METHODS: Patients undergoing EVLA for great saphenous vein insufficiency were randomized to receive EVLTAP or EVLA alone with sequential phlebectomy, if required. Outcomes included disease-specific quality of life (QoL) (Aberdeen Varicose Vein Questionnaire; AVVQ), requirement for secondary procedures, clinical severity (Venous Clinical Severity Score; VCSS), residual and recurrent varicose tributaries, and generic QoL. Patients were followed up for 5 years. RESULTS: Fifty patients were randomized equally into two parallel groups. The EVLTAP group had lower VCSS scores at 12 weeks (median 0 (i.q.r. 0-1) versus 2 (0-2); P <0·001), and lower AVVQ scores at 6 weeks (median 7·9 (i.q.r. 4·1-10·7) versus 13·5 (10·9-18·1); P < 0·001) and 12 weeks (2·0 (0·4-7·7) versus 9·6 (2·2-13·8); P = 0·015). VCSS and AVVQ scores were equivalent by 1 year, but only after 16 of 24 patients in the EVLA group, compared with one of 25 in the EVLTAP group (P < 0·001), had received a secondary intervention. From 1 to 5 years both groups had equivalent outcomes. CONCLUSION: EVLA with either concomitant or sequential management of tributaries is acceptable treatment for symptomatic varicose veins, with both treatments achieving excellent results at 5 years. Concomitant treatment of varicosities is associated with optimal improvement in both clinical disease severity and QoL.

The development of a Patients Concerns Inventory (PCI) to help reveal patients concerns in the head and neck clinic.

The purpose of the Patients Concerns Inventory (PCI) is to identify the concerns that patients would like to discuss during their consultation. The PCI covers a range of issues including hearing, intimacy, fatigue, financial/benefits, PEG tube, relationships, regret, support for family, and wound healing. It also lists MDT members that patients would like to see or be referred on to. The PCI is completed using a touch-screen computer (TST) immediately before consultation. Responses are networked into the consultation room. A 28 weeks pilot for one consultant ran from August 2007 with 123 (of maximum 150) patients. The median time to complete the TST was 8min. Patients most frequently selected fear of recurrence (37%), dental health/teeth (27%), chewing (24%), pain in head/neck (20%), fatigue/tiredness (19%), saliva (18%) and swallowing (18%). The two MDT members they wished to see were dentist (19%) and speech/language therapist (10%). The vast majority felt the PCI made a difference (quite a bit/very much) to their consultation as it made it 'a bit more personal', 'reminds them of the points they want discussed', 'allows the consultation to get straight to the point'. Although the PCI can raise many issues it did not noticeably prolong the consultation (median 8min with PCI, 7min without PCI). The Patients Concerns Inventory (PCI) helps focus the consultation onto patient needs and promotes multidisciplinary care. Following this very successful pilot the PCI is being rolled out to other consultants in the H & N clinic.
