Effect of unilateral adrenalectomy on the quality of life of patients with lateralized primary aldosteronism.

BACKGROUND: Primary aldosteronism (PA) is associated with an increased prevalence of anxiety and depression. Subnormal quality of life (QoL) scores in PA patients may be improved after surgical treatment. The aim of the study was to assess the impact of surgery on health-related QoL and depression status of patients suffering from PA, comparing the results with a control group of patients undergoing surgery for non-secreting adrenal tumors. METHODS: Data on QoL and depression status were prospectively collected, from January 2014 to January 2017, before, early after surgery (at 1 month) and at late follow up (at least 6 months) in patients with unilateral PA and in a control group with non-secreting adrenal tumors submitted to unilateral laparoscopic adrenalectomy. QoL was assessed using the Short Form 36 (SF-36) Health Survey for Physical (PCS) and Mental Component (MCS); the depression status by a 20-item depression scale (DS) questionnaire. RESULTS: Twenty-six PA patients and 15 controls were recruited. Biochemical cure of the disease was achieved following surgery in all PA patients; hypertension was cured in 31% of cases and improved in the remaining 69% of cases. No morbidity occurred in both groups. There were no significant differences between PA patients and controls concerning demographics, preoperative PCS, MCS and DS values. In patients with PA, MCS values improved at early (42.72 ± 13.68 vs 51.56 ± 9.03, p = 0.0005) and late follow up (42.72 ± 13.68 vs 51.81 ± 7.04, p < 0.0001); also DS values improved at early (15.92 ± 11.98 vs 8.3 ± 8.8, p = 0.0002) and late follow up (15.92 ± 11.98 vs 4.57 ± 6.11, p < 0.0001). In PA patients PCS values significantly improved at late follow up (51.02 ± 8.04 vs 55.85 ± 5.1, p = 0.013). Also in controls an improvement of MCS and DS scores was found at early and late follow up compared to preoperative values, while no significant differences in PCS were found. CONCLUSIONS: Both PA and non-secreting adrenal tumors affect health-related QoL, worsening MCS and DS scores. Adrenalectomy is effective in curing PA, and improving MCS and DS scores at early and late follow-up, in patients with PA and non-secreting adrenal tumors. In PA patient surgery also significantly improves PCS at late follow up.

Primary aldosteronism patients show skin alterations and abnormal activation of glucocorticoid receptor in keratinocytes.

Primary aldosteronism (PA) is a disease characterized by high aldosterone levels caused by benign adrenal tumors being the most frequent cause of secondary hypertension. Aldosterone plays vital physiological roles through the mineralocorticoid receptor (MR) but in certain cell types, it can also activate the glucocorticoid (GC) receptor (GR). Both MR and GR are structurally and functionally related and belong to the same family of ligand-dependent transcription factors that recognize identical GC regulatory elements (GREs) on their target genes. GCs play key roles in skin pathophysiology acting through both GR and MR; however, the effects of aldosterone and the potential association of PA and skin disease were not previously addressed. Skin samples from PA revealed histopathological alterations relative to control subjects, featuring epidermal hyperplasia, impaired differentiation, and increased dermal infiltrates, correlating with increased NF-κB signaling and up-regulation of TNF-A and IL-6 cytokines. PA skin samples also showed significantly higher expression of MR, GR, and HSD11B2. In cultured keratinocytes, aldosterone treatment increased GRE transcriptional activity which was significantly inhibited by co-treatment with GR- and MR-antagonists. This study demonstrates that high levels of aldosterone in PA patients correlate with skin anomalies and inflammatory features associated with abnormal GR/MR activation in epidermal keratinocytes.

Adrenal ganglioneuroma: The Padua Endocrine Surgery Unit experience.

BACKGROUND: Adrenal ganglioneuroma (AGN) is a rare tumor that originates from the gangliar cells of the sympathetic nervous system. It represents less than 5% of all adrenal masses. AGN occurs as a large mass, with benign behavior and no relevant symptoms and hormonal secretion, but it is often misdiagnosed because the preoperative radiological diagnosis is generally challenging. The aim of the present paper is to report the experience of a tertiary referral academic center regarding the management of AGN and review the relevant literature. METHODS: The demographic, diagnostic, surgical, and pathological findings of 666 consecutive patients who were adrenalectomized at the Padua Endocrine Surgery Unit between 1990 and 2015 were retrospectively reviewed in order to focus on AGN. RESULTS: The pathology confirmed AGN in 10 patients (1.5% of cases; median age 35 years, range 19-73). The diagnosis was incidental and never available before surgery. Eight patients were asymptomatic, two presented lower back and abdominal pain. The mass was non-secreting in all cases. Preoperative imaging techniques were inconclusive about the nature of the mass in all cases. The median size of the tumor was 55 mm (range 30-80). The laparoscopic approach was performed in 60% of cases. No recurrences occurred after surgery at a median follow-up of 10 years (range 1.7-18.2). CONCLUSION: The diagnosis of AGN may be challenging and most often occurs after surgery, since it is frequently confirmed by histological examination. Radical excision may be achieved by laparoscopic adrenalectomy, with a subsequent definitive cure and excellent prognosis at long term follow up.

Surgical approaches in hereditary endocrine tumors.

Endocrine tumors of thyroid, adrenal and parathyroid glands may be due to germline and inheritable mutations in 5-30% of patients. Medullary Thyroid Carcinoma, Pheochromocytoma, Paraganglioma, and Familial Primary Hyperparathyroidism are the most frequent entity. Hereditary endocrine tumors usually have a suggestive familial history; they occur earlier than sporadic variants, are multifocal, and have increased recurrence rates. They may be present as isolated variant or associated to other neoplasms in a syndromic setting. Genetic diagnosis should be preferably available before surgery because specific and targeted operative management are needed to achieve the best chance of cure. This review was aimed to discuss the surgical approaches for some of the most frequent hereditary endocrine tumors of thyroid, adrenal and parathyroid glands, focusing on medullary thyroid carcinoma, Pheochromocytoma, Paraganglioma and hereditary primary hyperparathyroidism (pHPT). Hereditary Medullary Thyroid Carcinoma is caused by RET mutations, and may be associated to Pheochromocytomas in MEN 2 setting. Total thyroidectomy and at least central neck nodal dissection is required. The availability of genetic screening allows prophylactic or early surgery in asymptomatic patients, with subsequent definitive cure. Hereditary Pheochromocytomas may be present in several syndromes (MEN 2, VHL, NF1, Paraganglioma/Pheochromocytoma syndrome); it may involve both adrenals; in these cases, a cortical sparing adrenalectomy should be performed to avoid permanent hypocorticosurrenalism. Hereditary Primary Hyperparathyroidism may frequently occur associated to MEN 1, MEN 2A, MEN 4, Hyperparathyroidism-Jaw Tumor Syndrome; it may involve all the parathyroid glands, requiring subtotal parathyroidectomy or total parathyroidectomy plus autotransplantation. In some cases, a selective parathyroidectomy might be performed.

Investigation of N-cadherin/ß-catenin expression in adrenocortical tumors.

ß-catenin is a multifunctional protein; it is a key component of the Wnt signaling, and it plays a central role in cadherin-based adhesions. Cadherin loss promotes tumorigenesis by releasing membrane-bound ß-catenin, hence stimulating Wnt signaling. Cadherins seem to be involved in tumor development, but these findings are limited in adrenocortical tumors (ACTs). The objective of this study was to evaluate alterations in key components of cadherin/catenin adhesion system and of Wnt pathway. This study included eight normal adrenal samples (NA) and 95 ACT: 24 adrenocortical carcinomas (ACCs) and 71 adrenocortical adenomas (ACAs). ß-catenin mutations were evaluated by sequencing, and ß-catenin and cadherin (E-cadherin and N-cadherin) expression was analyzed by quantitative reverse transcription PCR (qRT-PCR) and by immunohistochemistry (IHC). We identified 18 genetic alterations in ß-catenin gene. qRT-PCR showed overexpression of ß-catenin in 50 % of ACC (12/24) and in 48 % of ACA (21/44). IHC data were in accordance with qRT-PCR results: 47 % of ACC (7/15) and 33 % of ACA (11/33) showed increased cytoplasmic or nuclear ß-catenin accumulation. N-cadherin downregulation has been found in 83 % of ACC (20/24) and in 59 % of ACA (26/44). Similar results were obtained by IHC: N-cadherin downregulation was observed in 100 % (15/15) of ACC and in 55 % (18/33) of ACA. ß-catenin overexpression together with the aberrant expression of N-cadherin may play important role in ACT tumorigenesis. The study of differentially expressed genes (such as N-cadherin and ß-catenin) may enhance our understanding of the biology of ACT and may contribute to the discovery of new diagnostic and prognostic tools.

Overexpression of L-Type Amino Acid Transporter 1 (LAT1) and 2 (LAT2): Novel Markers of Neuroendocrine Tumors.

BACKGROUND: 6-18F-fluoro-L-3,4-dihydroxyphenylalanine (18F-FDOPA) PET is a useful tool in the clinical management of pheochromocytoma (PHEO) and medullary thyroid carcinoma (MTC). 18F-FDOPA is a large neutral amino acid biochemically resembling endogenous L-DOPA and taken up by the L-type amino acid transporters (LAT1 and LAT2). This study was conducted to examine the expression of the LAT system in PHEO and MTC. METHODS: Real-time PCR and Western blot analyses were used to assess LAT1 and LAT2 gene and protein expression in 32 PHEO, 38 MTC, 16 normal adrenal medulla and 15 normal thyroid tissue samples. Immunohistochemistry method was applied to identify the proteins' subcellular localization. RESULTS: LAT1 and LAT2 were overexpressed in both PHEO and MTC by comparison with normal tissues. LAT1 presented a stronger induction than LAT2, and their greater expression was more evident in PHEO (15.1- and 4.1-fold increases, respectively) than in MTC (9.9- and 4.1-fold increases, respectively). Furthermore we found a good correlation between LAT1/2 and GLUT1 expression levels. A positive correlation was also found between urinary noradrenaline and adrenaline levels and LAT1 gene expression in PHEO. The increased expression of LAT1 is also confirmed at the protein level, in both PHEO and MTC, with a strong cytoplasmic localization. CONCLUSIONS: The present study is the first to provide experimental evidence of the overexpression in some NET cancers (such as PHEO or MTC) of L-type amino acid transporters, and the LAT1 isoform in particular, giving the molecular basis to explain the increase of the DOPA uptake seen in such tumor cells.

Can Total Thyroidectomy Be Safely Performed by Residents?: A Comparative Retrospective Multicenter Study.

This retrospective comparative multicenter study aims to analyze the impact on patient outcomes of total thyroidectomy (TT) performed by resident surgeons (RS) with close supervision and assistance of attending surgeons (AS).All patients who underwent TT between 2009 and 2013 in 10 Units of endocrine surgery (8 in Italy, 1 in France, and 1 in UK) were evaluated. Demographic data, preoperative diagnosis, extension of goiter, type of surgical access, surgical approach, operative time, use and duration of drain, length of hospitalization, histology, and postoperative complications were recorded. Patients were divided into 3 groups: A, when treated by an AS assisted by an RS; B and C, when treated by a junior and a senior RS, respectively, assisted by an AS.The 8908 patients (mean age 51.1 ±â€Š13.6 years), with 6602 (74.1%) females were enrolled. Group A counted 7092 (79.6%) patients, Group B 261 (2.9%) and Group C 1555 (17.5%). Operative time was significantly greater (P < 0.001) in B (101.3 ±â€Š43.0 min) vs A (71.8 ±â€Š27.6 min) and C (81.2 ±â€Š29.9 min). Duration of drain was significantly lower (P < 0.001) in A (47.4 ±â€Š13.2 h) vs C (56.4 ±â€Š16.5 h), and in B (42.8 ±â€Š14.9 h) vs A and C. Length of hospitalization was significantly longer (P < 0.001) in C (3.8 ±â€Š1.8 days) vs B (2.4 ±â€Š1.0 days) and A (2.6 ±â€Š1.5 days). No mortality occurred. Overall postoperative morbidity was 22.3%: it was significantly higher in B vs A (29.5% vs 22.3%; odds ratio [OR] 1.46, 95% confidence interval [CI] 1.11-1.92, P = 0.006) and C (21.3%; OR 1.55, 95% CI 1.15-2.07, P = 0.003). No differences were found for recurrent laryngeal nerve palsy, hypoparathyroidism, hemorrhage, and wound infection. The adjusted ORs in multivariate analysis showed that overall morbidity remained significantly associated with Group B vs A (OR 1.48, 95% CI 1.12-1.96, P = 0.005) and vs C (OR 1.60, 95% CI 1.19-2.17, P = 0.002), while no difference was observed in Group A vs B + C.TT can be safely performed by residents correctly supervised. Innovative gradual training in dedicated high-volume hospitals should be proposed in order to allow adequate autonomy for the RS and safeguard patient outcome.

Neck ultrasonography for detection of non-recurrent laryngeal nerve.

BACKGROUND: Non-recurrent laryngeal nerve (NRLN) is a rare anatomical variant (0.3-6%) that is associated with some arterial abnormalities (absence of the brachiocephalic trunk and presence of a right aberrant subclavian lusorian artery). The availability of a preoperative diagnosis of NRLN may reduce the risk of nerve injuries. Preoperative ultrasonography (US) has been suggested as a reliable diagnostic tool to detect the arterial abnormalities associated with NRLN, but the literature is relatively scarce. This paper was aimed to review the literature, in order to offer an up to-date on this technique and its results. METHODS: A web search, focusing on humans, was performed by PubMed database, including papers published up to August 2016, using the key words "ultrasonography" AND "non-recurrent laryngeal nerve" or "nonrecurrent laryngeal nerve". RESULTS: Eight papers, including 3,740 patients who underwent neck US for the detection of NRLN were selected. Only five studies focused on the preoperative use of US. The incidence of NRLN varied between 0.4% and 1.94%. The sensitivity and specificity varied between 99-100% and 41-100%, respectively. CONCLUSIONS: US is a simple, non-invasive and cost-effective method to detect NRLN, also if its accuracy is not absolute. It may be used preoperatively and to prevent the intraoperative nerve damage, since the risk of NRLN palsies is significantly reduced when a preoperative diagnosis is available.

Increased and safer detection of nonrecurrent inferior laryngeal nerve after preoperative ultrasonography.

OBJECTIVES/HYPOTHESIS: Right nonrecurrent inferior laryngeal nerve (NRLN) is an anatomical variant reported with a variable prevalence (0.3%-6%). It is associated with some arterial abnormalities (absence of the brachiocephalic trunk and presence of a right aberrant subclavian lusorian artery) that may be identified by preoperative ultrasonography (pUS). NRLN represents a major morbidity risk factor during neck surgery. The aim of this study was to verify pUS accuracy in predicting NRLN and to assess the impact of this technique on NRLN detection rate and laryngeal morbidity. STUDY DESIGN: Retrospective. METHODS: The study included 1,477 patients undergoing thyroid and parathyroid surgery with right-side inferior laryngeal nerve exploration. pUS was performed in 878 patients (pUS group); no preoperative attempts were performed in the remaining 599 patients (controls). Demographics, disease type, intraoperative inferior laryngeal nerve anatomy, and laryngeal morbidity were compared. RESULTS: No differences occurred between the two groups concerning demographics and disease type. NRLN was detected in 17 patients (1.9%) of the pUS group and in four patients (0.6%) of controls (P < 0.05). pUS predicted NRLN in all cases, with an overall accuracy > 98%. Overall laryngeal nerves morbidity was 1.8% in the pUS group and 4.2% in the controls (P < 0.05). NRLN palsy never occurred in the pUS group, whereas it occurred three times in the controls (P < 0.005). CONCLUSION: NRLN is accurately predicted by pUS. It occurs more frequently than expected because it may be misdiagnosed when no preoperative suspicion is available. Preoperative NRLN detection by pUS prevents inferior laryngeal nerve injuries.

Approach to the surgical management of primary aldosteronism.

Primary aldosteronism (PA) is the most common cause of endocrine hypertension; it has been reported in more than 11% of referred hypertensive patients. PA may be caused by unilateral adrenal involvement [aldosterone producing adenoma (APA) or unilateral adrenal hyperplasia (UAH)], and bilateral disease (idiopathic adrenal hyperplasia). Only patients with unilateral adrenal hypersecretion may be cured by unilateral adrenalectomy, while patients with bilateral and non-surgically correctable PA are usually treated by mineralocorticoid receptor antagonists; thus the distinction between unilateral and bilateral aldosterone hypersecretion is crucial. Most experts agree that the referral diagnostic test for lateralization of aldosterone hypersecretion should be adrenal venous sampling (AVS) because the interpretation of other imaging techniques [computed tomography (CT), magnetic resonance imaging (MRI) and scintigraphy] may lead to inappropriate treatment. Adrenalectomy represents the elective treatment in unilateral PA variants. Laparoscopic surgery, using transperitoneal or retroperitoneal approaches, is the preferred strategy. Otherwise, the indications to laparoscopic unilateral total or partial adrenalectomy in patients with unilateral PA remain controversial. Adrenalectomy is highly successful in curing the PA, with correction of hypokalemia in virtually all patients, cure of hypertension in about 30-60% of cases, and a marked improvement of blood pressure values in the remaining patients. Interestingly, in several papers the outcomes of surgery focus only on blood pressure changes and the normalization of serum potassium levels is often used as a surrogate of PA recovery. However, the goal of surgery is the normalization of aldosterone, because chronically elevated levels of this hormone can lead to cardiovascular complications, independently from blood pressure levels. Thus, we strongly advocate the need of considering the postoperative normalization of aldosterone-renin ratio (ARR) as the main endpoint for determining outcomes of PA.

Outcome of surgical treatment of primary aldosteronism.

PURPOSE: The aim of this retrospective study was to analyze the early and long-term outcomes of the surgical treatment of primary aldosteronism (PA), the most common surgically correctable cause of endocrine hypertension. METHODS: Serum Potassium levels, blood pressure values, and aldosterone/renin ratio (ARR) were assessed in 128 patients undergoing unilateral adrenalectomy for PA, before and after surgery. The role of lateralizing techniques and the relationship between outcome and histopathology findings were also evaluated. RESULTS: Biochemical cure of PA (ARR and kalemia normalization) was achieved in 95 % of patients, at early follow-up. Single aldosterone-producing adenoma, multinodular hyperplasia, and diffuse hyperplasia were found in 46, 45, and 9 % of the patients, respectively. No relationship between histopathology and persistence or recurrence of PA was found. The use of further lateralizing techniques in addition to computed tomography or magnetic resonance was the main predictor of PA cure (p = 0.02); adrenal venous sampling (AVS) was more accurate than scintigraphy in PA lateralization (p < 0.05). After surgery, hypertension was cured in 55 % and improved in 36 % of patients. Female gender, a lower number of antihypertensive drugs, and a shorter duration of hypertension were the main predictors of hypertension cure. At long-term, recurrent PA occurred in 3.7 % of cases. CONCLUSIONS: Early diagnosis and correct lateralization of hyperaldosteronism by means of AVS are keys to achieve surgical cure of PA and PA-related hypertension. PA may be also caused by unilateral hyperplasia, which may be cured by unilateral adrenalectomy. Recurrences of PA are rare, although a prolonged follow-up is required.

The effects of acupuncture after thyroid surgery: A randomized, controlled trial.

BACKGROUND: Acupuncture is a safe and well-tolerated treatment for pain relief. Previous studies supported the effectiveness of several acupuncture techniques for postoperative pain. The aim of this randomized, controlled trial was to evaluate the efficacy of acupuncture in reducing pain after thyroid surgery. METHODS: We randomized 121 patients to a control group (undergoing only standard postoperative analgesic treatment with acetaminophen) and an acupuncture group, undergoing also either electroacupuncture (EA) or traditional acupuncture (TA). Pain was measured according to intraoperative remifentanil use, acetaminophen daily intake, Numeric Rating Scale (NRS), and McGill Pain Questionnaire on postoperative days (POD) 1-3. RESULTS: Acupuncture group required less acetaminophen than controls at POD 2 (P = .01) and 3 (P = .016). EA patients required less remifentanil (P = .032) and acetaminophen than controls at POD 2 (P = .004) and 3 (P = .008). EA patients showed a trend toward better NRS and McGill scores from POD 1 to 3 compared with controls. EA patients had a lower remifentanil requirement and better NRS and McGill scores than TA patients. No differences occurred between TA patients and controls. CONCLUSION: Acupuncture may be effective in reducing pain after thyroid surgery. EA is more useful; TA achieves no significant effects.

Adrenalectomy may improve cardiovascular and metabolic impairment and ameliorate quality of life in patients with adrenal incidentalomas and subclinical Cushing's syndrome.

BACKGROUND: Adrenalectomy represents the definitive treatment in clinically evident Cushing's syndrome; however, the most appropriate treatment for patients with subclinical Cushing's syndrome (SCS) with an adrenal incidentaloma remains controversial. This study was aimed to assess whether adrenalectomy may improve cardiovascular and metabolic impairment and quality of life compared with conservative management. METHODS: Twenty patients with adrenal incidentaloma underwent laparoscopic adrenalectomy for SCS, whereas 15 were managed conservatively. Hormonal laboratory parameters of corticosteroid secretion, arterial blood pressure (BP), glycometabolic profile, and quality of life (by the SF-36 questionnaire) were compared at baseline and the end of follow-up. RESULTS: The 2 groups were equivalent concerning all the examined parameters at baseline. In the operative group, laboratory corticosteroid parameters normalized in all patients but not in the conservative-management group (P < .001). In operated patients, a decrease in BP occurred in 53% of patients, glycometabolic control improved in 50%, and body mass index decreased; in contrast, no improvement or some worsening occurred in the conservative-management group (P < .01). SF-36 evaluation improved in the operative group (P < .05). CONCLUSION: Adrenalectomy can be more beneficial than conservative management in SCS and may achieve remission of laboratory hormonal abnormalities and improve BP, glycemic control, body mass index, and quality of life.

Unilateral adrenal hyperplasia: a novel cause of surgically correctable primary hyperaldosteronism.

BACKGROUND: Primary hyperaldosteronism may be caused by an aldosterone-producing adenoma (APA), which is correctable by unilateral adrenalectomy or by idiopathic adrenal hyperplasia, a bilateral disease without any indication for surgery. This study sought to assess the prevalence and the results of surgery in unilateral adrenal hyperplasia (UAH). METHODS: The study included 35 patients who underwent unilateral adrenalectomy because of primary hyperaldosteronism after unequivocal successful lateralization by adrenal venous sampling. Demographics, biochemical evaluation, and blood pressure were assessed pre- and postoperatively. Pathology was categorized as APA (isolated adenoma), nodular (multiple micromacronodules), and diffuse UAH (gland thickening without nodules). RESULTS: Pathology revealed 9 APAs and 23 nodular and 3 diffuse UAHs. Patients with APAs and UAHs were statistically similar regarding demographics and preoperative blood pressure levels. Bilateral adrenal involvement was evident at imaging in 10 patients (11% in APA versus 35% in UAH, P = NS). After surgery, biochemical cure of the disease was achieved in all patients; blood pressure levels normalized in 66.6% of patients and ameliorated in 22.2% in APA versus 34.6% and 50% in patients with UAH (P = NS). At a long-term follow-up, only 1 patient with nodular UAH experienced a biochemical recurrence of disease. CONCLUSION: UAH is not rare, sharing the same features of APA. When disease lateralization is confirmed by adrenal venous sampling, unilateral adrenalectomy achieves excellent long-term results.

Laparoscopic distal pancreatectomy: up-to-date and literature review.

Pancreatic surgery represents one of the most challenging areas in digestive surgery. In recent years, an increasing number of laparoscopic pancreatic procedures have been performed and laparoscopic distal pancreatectomy (LDP) has gained world-wide acceptance because it does not require anastomosis or other reconstruction. To date, English literature reports more than 300 papers focusing on LDP, but only 6% included more than 30 patients. Literature review confirms that LDP is a feasible and safe procedure in patients with benign or low grade malignancies. Decreased blood loss and morbidity, early recovery and shorter hospital stay may be the main advantages. Several concerns still exist for laparoscopic pancreatic adenocarcinoma excision. The individual surgeon determines the technical conduction of LDP, with or without spleen preservation; currently robotic pancreatic surgery has gained diffusion. Additional researches are necessary to determine the best technique to improve the procedure results.

Perianal Crohn's disease: is there something new?

Perianal lesions are common in patients with Crohn's disease, and display aggressive behavior in some cases. An accurate diagnosis is necessary for the optimal management of perianal lesions. Treatment of perianal Crohn's disease includes medical and/or surgical options. Recent discoveries in the pathogenesis of this disease have led to advances in medical and surgical therapy with good results. Perianal lesions in Crohn's disease remain a challenging aspect for both gastroenterologists and surgeons and lead to a greatly impaired quality of life for all patients affected by this disease. A multidisciplinary approach is mandatory to obtain the best results.

Long-term health-related quality of life after minimally invasive surgery for diverticular disease.

BACKGROUND AND AIMS: The aim of this multicentric study was to evaluate the disease specific and the generic quality of life in patients affected by colonic diverticular disease (DD) who had undergone minimally invasive or open colonic resection or who had been treated with medical therapy in the long-term follow-up. PATIENTS AND METHODS: Seventy-one consecutive patients admitted to the departments of surgery of Padova and Arzignano Hospitals for DD were interviewed: 22 underwent minimally invasive colonic resection, 24 had open resection, and 25 had only medical therapy. The interview focused on disease specific and generic quality of life, body image, and disease activity. RESULTS: Padova Inflammatory Bowel Disease Quality of Life (PIBDQL) was validated for the use in DD patients. PIBDQL scores were significantly worse in all patients with DD than those obtained by healthy subjects and it correlated with the symptoms score. The generic quality of life seemed similar in patients who had minimally invasive colonic resection compared with healthy subjects. Body Image Questionnaire scores correlated inversely with the presence of a stoma. CONCLUSIONS: Disease activity resulted as the only independent predictor of the disease-specific quality of life. In fact, DD affected bowel function and quality of life of patients in the long-term follow-up regardless of the type of therapy adopted. The presence of a stoma affected the patients' body image.

The results of surgery for mediastinal parathyroid tumors: a comparative study of 63 patients.

PURPOSE: Parathyroidectomy for ectopic mediastinal hyperfunctioning glands could be performed by transcervical approach, sternotomy, thoracotomy, and recently by thoracoscopic and mediastinoscopic approaches. This study was aimed to analyze the results of traditional and video-assisted parathyroidectomy for mediastinal benign hyperfunctioning glands. METHODS: Fifty-one upper mediastinal exploration by a conventional cervicotomy, 12 by video-assisted approaches (two thoracoscopy and 10 transcervical mediastinoscopy) and six by sternotomy were performed in 63 patients with primary hyperparathyroidism. RESULTS: Video-assisted and sternotomic parathyroid explorations achieved biochemical cure in all cases; following conventional transcervical mediastinal exploration, a persistent hyperparathyroidism occurred in 11.8% of patients, who were subsequently cured by sternotomic approach. No complications occurred after video-assisted parathyroidectomy, while an overall morbidity rate of 50% and 10% was found after sternotomic and conventional cervicotomic approaches. Postoperative pain and hospital stay were significantly increased following sternotomy; patient's subjective cosmetic satisfaction was significantly higher after video-assisted and conventional cervicotomic approaches. CONCLUSIONS: Conventional cervicotomic parathyroidectomy may achieve satisfactory results, especially for upper mediastinal glands. Sternotomic approaches are effective, but should be limited because of invasiveness and increased morbidity. In case of deep and lower hyperfunctioning mediastinal parathyroids, video-assisted approaches represent a less invasive, effective, and safe alternative and might be the technique of choice.
