Intraoperative neuromonitoring versus visual nerve identification for prevention of recurrent laryngeal nerve injury in adults undergoing thyroid surgery

This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: To assess the effects of intraoperative neuromonitoring (IONM) versus visual nerve identification for prevention of recurrent laryngeal nerve injury in adults undergoing thyroid surgery

Total or near-total thyroidectomy versus subtotal thyroidectomy for multinodular non-toxic goitre in adults

Background Total thyroidectomy (TT) and subtotal thyroidectomy (ST) are worldwide treatment options for multinodular non-toxic goitre in adults. Near TT, defined as a postoperative thyroid remnant less than 1 mL, is supposed to be a similarly effective but safer option than TT. ST has been shown to be marginally safer than TT, but it may leave an undetected thyroid cancer in place. Objectives The objective was to assess the effects of total or near-total thyroidectomy compared to subtotal thyroidectomy for multinodular non-toxic goitre. Search methods We searched the Cochrane Library, MEDLINE, PubMed, EMBASE, as well as the ICTRP Search Portal and ClinicalTrials.gov. The date of the last search was 18 June 2015 for all databases. No language restrictions were applied. Selection criteria Two review authors independently scanned the abstract, title or both sections of every record retrieved to identify randomised controlled trials (RCTs) on thyroidectomy for multinodular non-toxic goitre for further assessment. Data collection and analysis Two review authors independently extracted data, assessed studies for risk of bias and evaluated overall study quality utilising the GRADE instrument. We calculated the odds ratio (OR) and corresponding 95% confidence interval (CI) for dichotomous outcomes. A random-effects model was used for pooling data. Main results We examined 1430 records, scrutinized 14 full-text publications and included four RCTs. Altogether 1305 participants entered the four trials, 543 participants were randomised to TT and 762 participants to ST. A total of 98% and 97% of participants finished the trials in the TT and ST groups, respectively. Two trials had a duration of follow-up between 12 and 39 months and two trials a follow-up of 5 and 10 years, respectively. Risk of bias across studies was mainly unknown for selection, performance and detection bias. Attrition bias was generally low and reporting bias high for some outcomes. In the short-term postoperative period no deaths were reported for both TT and ST groups. However, longer-term data on all-cause mortality were not reported (1284 participants; 4 trials; moderate quality evidence). Goiter recurrence was lower in the TT group compared to ST. Goiters recurred in 0.2% (1/425) of the TT group compared to 8.4% (53/632) of the ST group (OR 0.05 (95% CI 0.01 to 0.21); P < 0.0001; 1057 participants; 3 trials; moderate quality evidence). Re-intervention due to goitre recurrence was lower in the TT group compared to ST. Re-intervention was necessary in 0.5% (1/191) of TT patients compared to 0.8% (3/379)of ST patients (OR 0.66 (95% CI 0.07 to 6.38); P = 0.72; 570 participants; 1 trial; low quality evidence). The incidence of permanent recurrent laryngeal nerve palsy was lower for ST compared with TT. Permanent recurrent laryngeal nerve palsy occurred in 0.8% (6/741) of ST patients compared to 0.7% (4/543) of TT patients (OR 1.28, (95% CI 0.38 to 4.36); P = 0.69; 1275 participants; 4 trials; low quality evidence). The incidence of permanent hypoparathyroidism was lower for ST compared with TT. Permanent hypoparathyroidism occurred in 0.1% (1/741) of ST patients compared to 0.6% (3/543) of TT patients (OR 3.09 (95% CI 0.45 to 21.36); P = 0.25; 1275 participants: 4 trials; low quality evidence). The incidence of thyroid cancer was lower for ST compared with TT. Thyroid cancer occurred in 6.1% (41/669) of ST patients compared to 7.3% (34/465)of TT patients (OR 1.32 (95% CI 0.81 to 2.15); P = 0.27; 1134 participants; 3 trials; low quality evidence). No data on health-related quality of life or socioeconomic effects were reported in the included studies. Authors' conclusions The body of evidence on TT compared with ST is limited. Goiter recurrence is reduced following TT. The effects on other key outcomes such as re-interventions due to goitre recurrence, adverse events and thyroid cancer incidence are uncertain. New long-term RCTs with additional data such as surgeons level of experience, treatment volume of surgical centres and details on techniques used are needed

Thyroid nodule morphology affects the efficacy of ultrasound-guided interstitial laser ablation: a nested case-control study.

AbstractPurpose: The literature reports a wide range of percentages of ablation in the treatment of thyroid nodules. The aim of this nested case-control study was to evaluate whether the different morphological (well-defined vs. agglomerate) characteristics of nodules affect the success rate. Materials and methods: We selected 20 patients with a single and /or dominant well-defined nodule (group 1) and 20 with a nodular formation resulting from the fusion of multiple nodules (group 2). All the nodules were treated by the laser method receiving the same energy. Results: At 6 months, patients in group 1 showed a greater decrease in volume than those in group 2. These differences were more evident after 12 months. Conclusions: Our study demonstrates that the efficacy of laser treatment can be predicted by nodule morphology and contributes to explaining the wide differences in the percentages of ablation reported in literature

Isolated cardiophrenic angle node metastasis from ovarian primary. report of two cases

Ovarian cancer is the most lethal gynaecologic malignancy. It usually spreads out of the abdomen involving thoraco-abdominal organs and serosal surface. This disease is poorly curable and surgery, at early stage, is supposed to achieve the best survival outcome. In systemic dissemination, chemiotherapy is indicated, sometimes with neoadjuvant aim. The most common clinical expressions of advanced ovarian carcinoma are multiple adenopathy, neoplastic pleuritis, peritoneal seeding and distant metastasis, mainly hepatic and pulmonary. Isolated adenopathy of the mediastinum is rare and isolated bilateral have never been described before. We report two cases of isolated bilateral cardiophrenic angle lymphnode metastasis from ovarian carcinoma, without peritoneal and pleural involvement. Both patients were successfully resected through minimally invasive thoracic surgery. About the role of surgery, few data are available but survival seems to be longer after resection thus, more investigation is required to make the indication to surgery more appropriate in advanced cases

Predictivity of clinical, laboratory and imaging findings in diagnostic definition of palpable thyroid nodules. A multicenter prospective study

Abstract PURPOSE: To assess the role of clinical, biochemical, and morphological parameters, as added to cytology, for improving pre-surgical diagnosis of palpable thyroid nodules. METHODS: Patients with a palpable thyroid nodule were eligible if surgical intervention was indicated after a positive or suspicious for malignancy FNAC (TIR 4-5 according to the 2007 Italian SIAPEC-IAP classification), or two inconclusive FNAC at a 653 months interval, or a negative FNAC associated with one or more risk factor. Reference standard was histological malignancy diagnosis. Likelihood ratios of malignancy, sensitivity, specificity, negative (NPV), and positive predictive value (PPV) were described. Multiple correspondence analysis (MCA) and logistic regression were applied. RESULTS: Cancer was found in 433/902 (48%) patients. Considering TIR4-5 only as positive cytology, specificity, and PPV were high (94 and 91%) but sensitivity and NPV were low (61 and 72%); conversely, including TIR3 among positive, sensitivity and NPV were higher (88 and 82%) while specificity and PPV decreased (52 and 63%). Ultrasonographic size 653\u2009cm was independently associated with benignity among TIR2 cases (OR of malignancy 0.37, 95% CI 0.18-0.78). In TIR3 cases the hard consistency of small nodules was associated with malignity (OR: 3.51, 95% CI 1.84-6.70, p\u2009<\u20090.001), while size alone, irrespective of consistency, was not diagnostically informative. No other significant association was found in TIR2 and TIR3. CONCLUSIONS: The combination of cytology with clinical and ultrasonographic parameters may improve diagnostic definition of palpable thyroid nodules. However, the need for innovative diagnostic tools is still high

Can the measurement of amylase in drain after distal pancreatectomy predict post-operative pancreatic fistula?

The most frequent reason for performing a distal pancreatectomy is the presence of cystic or neuroendocrine tumors, in which the distal pancreatic stump is often soft and non fibrotic. This parenchymal consistence represents the main risk factor for post-operative pancreatic fistula. In order to identify the fistula and assessing its severity postoperative monitoring of amylase from intraperitoneal drains is important

Ghost Ileostomy with or without abdominal parietal split

<p>Abstract</p> <p>Background</p> <p>In patients who undergo low anterior rectal resection, the fashioning of a covering stoma (CS) is still controversial. In fact, a covering stoma (ileostomy or colostomy) is worsened by major complications related to the procedure, longer recovery time, necessity of a re-intervention under general anesthesia for stoma closure and poorer quality of life. The advantage of Ghost Ileostomy (GI) is that an ileostomy can be performed only when there is clinical evidence of anastomotic leakage, without performing further interventions with related complications when anastomotic leak is absent and therefore the procedure is not necessary. Moreover, in case of anastomotic dehiscence and necessity of delayed stoma opening, mortality and morbidity in patients with GI are comparable with the ones that occur in patients which had a classic covering stoma. On the other hand, is simple to think about the possible economic saving: avoiding an admission for performing the closure of the ileostomy, with all the costs connected (OR, hospitalization, post-operative period, treatment of possible complications) represents a huge saving for the hospital management and also raise the quality of life of the patients.</p> <p>Methods</p> <p>In this study we prospectively analyzed 20 patients who underwent anterior extra-peritoneal rectum resection for rectal carcinoma with TME and fashioning of GI realized with or without abdominal parietal split.</p> <p>Results</p> <p>In the group of patients that received a GI without split laparotomy mortality was absent and in one case an anastomotic leak occurred. In the group of patients in which GI with split laparotomy was fashioned, one death occurred and there were one case of infection and one respiratory complication. Clinical follow-up was 12 months.</p> <p>Conclusions</p> <p>The use of different techniques for fashioning a GI do not present significant differences when they are performed by expert surgeons, but further evidence is needed with more randomized trials, in order to have more data supporting the clinical observation.</p
