RESUMO

PURPOSE: Spigelian Hernia (SH) is characterized by the protrusion of abdominal viscera or preperitoneal fat through a defect in the spigelian aponeurosis. The objective of this systematic review was to evaluate current literature on Spigelian Hernias in adult population and elucidate their characteristics and preferable management. METHODS: MEDLINE and Scopus bibliographical databases were systematically searched (last search: 31st January 2024) for studies concerning SHs. RESULTS: Two hundred and thirty-four articles met predefined inclusion criteria and concerned collectively 1,629 patients with SHs (58.7% females) with an age of 62.32 ± 17.71 (mean ± SD) years and a BMI of 28.56 ± 7.34 (mean ± SD) kg/m2. A minimally invasive approach was opted at 46.8% of cases, while a mesh was implemented at 67.9% of cases. Postoperative length of hospital stay was 2.8 ± 2.9 (mean ± SD) days. Following individual cases analysis, open surgery was preferable at emergency setting (OR: 2.45; 95% CI: 1.36-4.41; p-value: 0.003), and minimally invasive approaches were associated with shorter length of hospital stay [2 (1-9) vs. 5 (1-22) days; p-value: <0.001]. Overall, thirty-day postoperative morbidity and mortality rates reached 7.0% and 0.3% respectively. CONCLUSION: SH is a rare ventral hernia, and it concerns most frequently overweight women. Open surgical approach is preferred in emergency cases, while laparoscopic surgery is associated with shorter hospitalization. Further comparative studies are necessary to determine optimal surgical approach.

RESUMO

BACKGROUND: Two main minimal access adrenalectomy techniques are available: laparoscopic transperitoneal (LTA) and posterior retroperitoneoscopic adrenalectomy (PRA). This study aims to compare these approaches in an updated meta-analysis of randomised controlled (RCT) and non-randomised comparative (NRT) trials. METHODS: A systematic search of comparative LTA and PRA studies was performed. Standard demographic and surgical data were recorded. Outcome measures compared included: operative time, estimated blood loss (EBL), conversion to open, post-operative pain, time to oral intake and ambulation, early morbidity, hospital length of stay (HLOS) and mortality. Quality of RCTs and NRTs was assessed using Cochrane and ROBINS-I, respectively, and heterogeneity using the I2 test. Dichotomous and continuous variables were compared using odds ratios and mean/standard difference. Studies were then combined using the Mantel-Haenszel method. Meta-analysis was performed by fixed- and random-effect models. RESULTS: Following exclusions, 12 studies were included in the analysis: 3 RCTs and 9 NRTs. These reported a total of 775 patients: 341 (44%) PRA and 434 (56%) LTA. Demographics were similar except for tumour size which was smaller (by 0.78 cm) in PRA (p = 0.003). Significant differences in outcome were seen in EBL (18 mls less in PRA, p = 0.006), time to oral intake (3.4 h sooner in PRA p = 0.009) and HLOS (shorter in PRA by 0.84 day, p = 0.001). CONCLUSIONS: This analysis demonstrates that while PRA tends to be performed for smaller tumours it allows for less EBL, earlier post-operative oral intake and shorter hospital stays. In appropriately selected patients, it represents an invaluable tool in the endocrine surgeon's armamentarium.

RESUMO

OBJECTIVE: Gestational primary hyperparathyroidism (PHPT) is an endocrinological disorder with serious outcomes for both women and neonates. The aim of our study was to present the current evidence concerning the perioperative outcomes of pregnant women with PHPT who underwent parathyroidectomy during pregnancy. METHODS: A meticulous systematic review of the literature published before February 2020 and all studies which presented perioperative and pregnancy outcomes off pregnant women who underwent parathyroidectomy for PHPT, were included. RESULTS: A total of 53 were finally included, which reported 92 pregnant women who had parathyroidectomy during their pregnancy. A total of 46 patients were hospitalized due to significant complications of PHPT before their parathyroidectomy. With regards to surgical approach, 52.2% of patients underwent minimally invasive parathyroidectomy (MIP), while bilateral neck exploration (BNE) was 41.3% of cases. Only 4 women was not cured, whereas transient hypocalcemia was occurred in 18 patients. All cases proceeded to deliveries of healthy neonates, after their parathyroidectomy. CONCLUSIONS: Parathyroidectomy during pregnancy is a safe and effective treatment option with minimum complications and probably should be considered as the treatment of choice in specific group of pregnant women with PHPT.

RESUMO

Infantile hepatic hemangioma (IHH) is a common vascular tumor, distinctive for its perinatal presentation, rapid growth during the first year of life, and subsequent involution. Although they generally follow a benign course, some tumors have been reported to undergo malignant transformation. The diagnosis of IHH is based on patient's medical history, physical examination, and imaging. Moreover, the management of this vascular tumor is based on clinical presentation and includes observational, medical, surgical, and radiological interventional treatment options. The present review presents the currently available data in the literature on the diverse aspects of the terminology, epidemiology, clinical presentation, pathogenesis, diagnosis, indications for surgery, malignant potential, and long-term outcomes of these tumors.Conclusion: No formal guidelines have yet been established for the treatment of these hepatic lesions, and the therapeutic strategies implemented vary widely from simple observation to medical, radiological, and surgical interventions in the prism of multidisciplinary teams.What is Known:• Infantile hepatic hemangioma is the most common benign tumor of the liver in infancy, but despite its benign nature, it can present with life-threatening complications.• The treatment strategies range from simple observation to a series of medical, surgical, and radiological interventions.What is New:• This review gives an overview of the developments and current status about the management of IHH.• The aim of this study is to clear up the confusion and controversy that exists about terminology, diagnosis, and treatment of IHH.

RESUMO

Endometriosis is characterized by the presence of endometrial-like tissue and stroma in extra-uterine locations. Hepatic endometriosis (HE) is one of the rarest forms of extrapelvic endometriosis. We aimed to summarize the existing evidence on HE with special consideration to natural history, diagnosis and surgical treatment. Three electronic databases were systematically searched for articles published up to March 2019. All appropriate observational studies and case reports addressing cases of women with HE were considered eligible for inclusion. A total of 27 studies which comprised 32 patients with HE were included. Mean age of patients was 39.7 years. Ten (62.5%) were nulliparous and 24 (75%) were women of reproductive age. Eleven patients (36.7%) had a history of pelvic endometriosis of various sites. Abdominal pain was the primary symptom in 28 patients (87.5%). Preoperative diagnosis of endometriosis was available for 5 patients and 6 underwent a preoperative diagnostic procedure. Cyst resection, minor and major liver resections were performed in 14/31, 9/31 and 8/31 patients, respectively. Preoperative diagnosis of HE is challenging due to variable radiologic features and clinical symptomatology. Nonetheless, it should be considered in the differential diagnosis of a liver mass especially in premenopausal women with a history of endometriosis. The type of resection of the endometriotic lesion is based on the extent and the location of the disease and presented with favourable outcomes concerning morbidity, symptom relief and recurrence.

RESUMO

Esophageal cancer is characterized by profound changes in body composition due to dysphagia and generalized cachexia. Sarcopenia or muscle wasting is a component of cachexia associated with poor postoperative performance status. The skeletal muscle index (SMI) calculated by computed tomography scans at the level of the third lumbar vertebra is an easily quantifiable and reproducible measure of sarcopenia. The aim of this meta-analysis is to investigate the impact of preoperative sarcopenia (low SMI) on postoperative complications after esophagectomy for neoplastic lesions. In this context, a comprehensive literature search was undertaken to identify studies reporting short-term postoperative outcomes in relation to their preoperative SMI values. Cumulative risk ratios (RR) and risk differences (RD) and their respective 95% confidence intervals (CIs) were calculated using a random-effect model. A total of 11 studies incorporating 1,979 total patients (964 patients with sarcopeniaversus 1,015 without sarcopenia) were included in the final analysis. The results demonstrated a significant increase in overall morbidity (RR 1.16, 95% CI 1.01-1.33), respiratory complications (RR 1.64, 95% CI 1.21-2.22) and anastomotic leaks (RR 1.39, 95% CI 1.10-1.76) in patients with sarcopenia. No statistically significant difference was noted in overall mortality (RD 0, 95% CI -0.02-0.02) or Clavien-Dindo grade III or greater complications (RR 1.17, 95% CI 0.96-1.42). The above results demonstrate the validity of the SMI as a predictive factor for post-esophagectomy complications. Although the risk associated with sarcopenia is not prohibitive for surgery, patients with low SMI require closer vigilance during their postoperative course due to the increased propensity for respiratory and anastomotic complications.

RESUMO

BACKGROUND: Temporary hepatic ischemia is inevitable during open aortic surgery when supraceliac clamping is necessary, as in thoracoabdominal or pararenal aneurysms. Remote ischemic preconditioning (RIPC) has been described as a potential protective means against ischemia-reperfusion injury (IRI) in various tissues including the liver. The aim of this experimental study was to detect the effect of RIPC on liver IRI in a model of supraceliac aortic cross-clamping. METHODS: An animal study was performed. Four groups of 6 swines each were examined: the control (sham) group, the ischemia-reperfusion (IR) group, and 2 remote ischemic preconditioning groups (RIPC I and RIPC II group). In the IR group, the animals underwent a complete cessation of the splanchnic arterial circulation for 30 min by a concomitant occlusion of the supraceliac and the infrarenal aorta. In the RIPC groups, a remote preconditioning was applied before the splanchnic ischemia. This consisted of a temporary occlusion of the infrarenal aorta for 15 min followed by 15 min of reperfusion (RIPC I group), and 3 cycles of 5 min similar ischemia, followed by 5 min of reperfusion each (RIPC II group). All animals were followed for 24 hr after the ischemia (reperfusion period). The liver ischemia-reperfusion injury was assessed by examining specific serum biomarkers indicating the magnitude of metabolic injury from selective blood samples of the hepatic circulation. In particular, the following parameters were examined: C-reactive protein, interleukin 6, tumor necrosis factor a, ferritin, and L-arginine. RESULTS: All parameters were affected in the IR group as compared to the sham group. Both RIPC groups developed a less serious change as compared to the IR group, in all examined parameters. CONCLUSIONS: In an animal study of splanchnic ischemia produced in a way to this produced during a supraceliac aortic aneurysm open repair, the remote ischemic preconditioning seemed to attenuate the effect of hepatic ischemia-reperfusion injury. CLINICAL RELEVANCE: Remote ischemic preconditioning produced with short bouts of ischemia of the lower body by temporary clamping of the infrarenal aorta might be used as a means of decreasing the detrimental effects of hepatic ischemia-reperfusion injury after supraceliac aortic cross-clamping. This was found in a swine model of suprarenal AAA open repair by studying the variance of certain biological biomarkers in selective blood samples retrieved from the hepatic vein.

RESUMO

OBJECTIVES: The Thyroidectomy-Related Voice Questionnaire (TVSQ) is a useful tool in the detection of voice changes and dysfunctions and the diagnosis of other symptoms related to transient or permanent laryngeal nerve damage in patients after thyroidectomy. The aim of our study is the translation and validation of (TVSQ) in the Greek language and in Greek population for the first time. METHODS: The TVSQ was translated from English to Greek and vice versa by two independent researchers, while before the application of the TVSQ in clinical practice, a control group of 20 people was used. The following methods were used for the weighting and analysis of the TVSQ: Polychoric correlation, Cronbach's alpha, confirmatory factor analysis, and item response theory (IRT). RESULTS: Polychoric correlations revealed that questions 1-10 have a strong positive correlation with each other, while the correlation of the rest of the TVSQ items is positive. Subsequently, for the first subgroup of questions ("voice change") Cronbach's alpha was equal to 0.950, while for the second ("throat and neck discomfort") Cronbach's alpha was equal to 0.846. Thus, we conclude that the internal consistency reliability is high for both subgroups of TVSQ questions. With the IRT method we showed that for the first subgroup of questions ("voice change"), the item with the least predictive value is question 5, while for the second subgroup of questions ("throat and neck discomfort"), the item with the least educational value was question 15. CONCLUSIONS: Our team translated and validated the TVSQ with the above statistical methods in the Greek language, so that it can be used as a valuable tool in clinical practice, and more specifically in patients undergoing thyroidectomy. TVSQ can play a significant role on the diagnosis of either postoperative voice disorders and other symptoms related to thyroidectomy.

RESUMO

The incidence of thyroid cancer has increased over recent years due to the fact that several diagnostic tools, such as neck ultrasound and fine-needle aspiration, are being ever more widely adopted. Lately, another modality which might provide significant information preoperatively on the aggressiveness of a thyroid tumor, its prognosis, and its recurrence rate is molecular testing. We reviewed the literature with regard to the role of preoperative molecular testing in patients with Bethesda V and Bethesda VI thyroid nodules and its impact on choice of the optimal treatment strategy. Several molecular mutations and alterations are associated with thyroid cancer and its biological behavior, such as BRAF-V600E, RET, and TERT promoter. Although the value of preoperative molecular testing for indeterminate nodules (Bethesda III and Bethesda IV) have been analyzed in numerous studies, the impact of preoperative molecular testing on Bethesda V and Bethesda VI thyroid nodules is not adequately described in the current literature. The preoperative recognition of specific molecular mutations, such as BRAFV600E and TERT promoter mutation, might provide more individualized management for thyroid cancer patients by altering the surgical approach and the extent of surgery for patients diagnosed with a more aggressive or iodine-resistant subtype of thyroid cancer.Thyroid cancer is characterized by multiple genetic mutations and alterations and, as a result, preoperative molecular testing of malignant nodules could be a very useful tool for surgeons, enabling them to decide on the most appropriate surgical approach for each patient.

RESUMO

Primary hydatid cysts (PHCs) in the extremities are uncommon, presenting in the majority of cases with atypical clinical features. Radical surgical excision remains the mainstay of treatment. The aim of our study was to accumulate the already published data on PHCs in the extremities in terms of demographic, diagnostic, and therapeutic aspects. Three electronic databases were meticulously searched for articles published until 2024. A total of 85 studies comprising 118 patients were finally included in our review. Sixteen patients (13.5%) were diagnosed with a hydatid cyst in their upper extremity, 94 (79.7%) with a PHC in the lower extremity, and eight (6.8%) with an echinococcal cyst in the axilla. Pain and swelling were the most frequent symptoms, whereas only two patients were completely asymptomatic. The mean lesion size was 11.6 ± 7.1 cm. Preoperative serology investigation was reported in 82 out of 118 (69.5%) patients; among them, 33 (44.6%) cases had a positive preoperative serology test. The vast majority of patients (96.6%) were treated with an interventional procedure either surgical or radiological, and only seven experienced postoperative complications. No anaphylactic reaction was described perioperatively. Although preoperative diagnosis of PHCs is challenging, they should be considered in the differential diagnosis of soft tissue lesions. Treatment strategies should be individualized on a patient basis, while radical surgical excision remains the gold standard treatment.

RESUMO

Bone metastases from thyroid cancer are mainly rare, while sternal metastases are extremely uncommon. Bone metastases might be either synchronous or metachronous to primary thyroid cancer. A 60-year-old male patient presented to our department with a painful, fixed and firm sternal mass. Preoperative imaging studies, such as neck ultrasound (US) and computed tomography (CT) of the chest, revealed a 6.5 cm nodule of the right thyroid lobe with high-risk malignancy characteristics and a massive metastatic mass of the anterior mediastinal, which was extended from the sternal notch to the third intercostal space. The diagnosis of papillary thyroid carcinoma with sternal metastatic lesions was established. After meticulous discussion in the multidisciplinary board of our hospital, a total thyroidectomy plus en-bloc resection of this massive sternal metastasis and adjuvant radioiodine therapy were decided. Eight months postoperatively, no recurrence has occurred in this patient. R0 resection of isolated bone metastasis of thyroid origin is still an optimal therapeutic decision for these patients. In cases of sternal metastasis, radical surgical resection with negative margins, including both resection of the lesion and reconstruction of the chest wall, in order to successfully maintain the chest wall's stability, is recommended.

RESUMO

Robotic-assisted surgery continues to gain ground over conventional surgical methods, due to reported better results regarding the aesthetic outcome and the decreased percentage of complications. Although latissimus dorsi flap harvesting for breast reconstruction has been already used for several years, a plethora of serious complications has been reported. Recently, minimally invasive surgical approaches, such as robotic-assisted technique, have been suggested with conflicting outcomes to overcome technical difficulties. Therefore, the literature review was conducted regarding robotic-assisted harvesting of the latissimus dorsi flap for breast reconstruction. A narrative review of the contemporary literature was performed in the PubMed database for the use of robotic-assisted surgery of latissimus dorsi muscle flap harvesting for breast reconstruction. Appropriate search terms were used, and specific inclusion and exclusion criteria were applied. Five studies met the inclusion criteria. A total of 32 cases of robotically assisted harvesting of pedicled latissimus dorsi muscle flap for implant-based breast reconstruction have been identified. All flaps were successfully harvested without converting in the traditional open procedure. There were no significant postoperative complications, expect from few cases of postoperative seromas, which were conservatively managed. Additionally, all patients were satisfied with their postoperative cosmetic outcome. The robotic-assisted harvesting technique of the latissimus dorsi flap for breast reconstruction is safe and comparable to the conventional methods. Reduced hospital stays and superior aesthetic outcome are the main advantages, while total cost and the difficulty of reaching the learning curve plateau are the main concerns regarding this modern and minimally invasive surgical approach.

RESUMO

The presence of ascites is a common clinical presentation in gynecologic oncology patients. Hemorrhagic ascites (HA) due to endometriosis is a rare presentation that can be easily misdiagnosed as ovarian malignancies. The present study aims to update the currently available knowledge on the characteristics of patients presenting with HA due to endometriosis. A systematic search was conducted for articles published from January 2000 to July 2020 using the Medline, Scopus, and Google Scholar databases along with the references of the full-text articles retrieved. Papers describing cases of women over 18 years with or without previous history of endometriosis were assessed. Only cases with histologically proven hemorrhagic ascites of endometriosis origin were included. Twenty-nine studies (27 case reports and two case series) comprising 32 patients were evaluated. The mean patients' age was 32 years, while six of the patients had a previous history of endometriosis. The mean amount of drained ascitic fluid was 4,200 mL, whereas three patients underwent thoracentesis due to pleural effusions. The treatment options included not only medical but also surgical therapies. Fertility preservation was achieved in 27 patients, while two of them achieved pregnancy with in vitro fertilization (IVF) techniques. Endometriosis-related hemorrhagic ascites is a relatively rare expression of the disease. Endometriosis-related hemorrhagic ascites should be considered in the differential diagnosis (DD) of women with ascites and clinical suspicion of endometriosis. The available literature is limited to case reports and case series and thus indicates further research in the field to decode the pathophysiology of the disease and decide on the optimal treatment.

RESUMO

Biliary mucinous cystic neoplasms are very rare tumors of the biliary tract with malignant potential. Preoperative diagnosis is challenging, as clinical, biochemical and radiological features are not specific. Surgical resection with negative margins is the gold standard treatment for these uncommon lesions. A 55-year-old woman presented at the Third Department of Surgery (Attikon University Hospital, Athens, Greece) with a history of mild right upper quadrant (RUQ) abdominal pain and jaundice. A 2-cm lesion in the distal common bile was identified by imaging. Following discussion in our multidisciplinary board meeting the patient underwent a pylorus preserving pancreatoduodenectomy, and histopathological examination revealed an ovarian-stromal type intraductal mucinous cystic neoplasm of the extra hepatic biliary. Since biliary mucinous cystic neoplasms are characterized by malignant transformation and high rates of recurrence, surgical resection with negative margins is the treatment of choice for both non-invasive and invasive biliary mucinous cystic neoplasms.

RESUMO

INTRODUCTION: Hepatic regeneration is a complex process involving a multitude of well-timed molecular operations. Ursodeoxycholic acid (UDCA) is postulated to exert a protective effect against oxidative stress and enzymatic degradation of the extracellular matrix, in turn potentiating the regenerative response. The aim of the present animal study is to evaluate the impact of UDCA administration in liver tissue expression of cyclooxygenase-2 (COX-2) in a setting of acute liver failure achieved by 80% hepatectomy. MATERIALS AND METHODS: Twenty-four adult male Sprague-Dawley rats were randomly assigned to an experimental (UDCA) and a control group. Animals in the UDCA received oral pretreatment with UDCA for 14 days via feeding tube, while animals in the control group received saline. All animals underwent resection of approximately 80% of the liver parenchyma. Tissue and blood sample collection were performed 48 hours postoperatively. RESULTS: The postoperative mitotic index and Ki-67 levels were found to be elevated in the UDCA group (43±11.4 and 13.7±24.7 versus 31±16.7 and 7.6±5.7), albeit without any statistical significance. Pretreatment with UDCA significantly decreased COX-2 expression levels (p=0.28) as well as serum tumor necrosis factor α (TNFα) levels (37.3±10.9 pg/mL versus 75.4±14.4 pg/mL, p=0.004). COX-2 expression score was observed to be weakly correlated to Ki-67 levels in both groups. Although COX-2 expression score was not correlated with serum TNFα levels in the control group, animals pretreated with UDCA exhibited moderate correlation (r=0.45). CONCLUSION: Preoperative administration of UDCA exerts a suppressive effect on tissue expression of COX-2 following 80% hepatectomy and enforces a positive correlation between COX-2 and serum TNFα levels, suggesting that UDCA preconditions liver tissue to display an enhanced regenerative response to circulating cytokines, most notably TNFα. The weak association of COX-2 with Ki-67 expression levels suggests that COX-2 may be of secondary importance during the early phases of liver regeneration.

RESUMO

Extragonadal germ cell tumors are uncommon in adults and only 2-5% of teratomas develop in extragonadal sites. Primary thyroid teratomas represent <0.1% of all primary thyroid gland neoplasms. In the present report, a case of primary thyroid teratoma in a 65-year-old female is described. Furthermore, the current literature regarding patients who were diagnosed with primary thyroid teratoma and underwent surgical resection was systematically reviewed. A total of 15 studies of 27 patients (age range, 17-65 years). Growing mass or neck swelling were the primary symptoms in 14 patients (51.8%). Only one (5.5%) patient was preoperatively diagnosed with malignant thyroid teratoma. All patients underwent thyroidectomy, but 6 cases had more advanced surgery, including lymph node dissection. A total of 12 patients received a combination of adjuvant chemoradiation postoperatively, 10 (45.4%) patients reported recurrence of disease and 8 (29.6%) were postoperatively diagnosed with distant metastases. A total of 9 (39.1%) patients died due to progression of the disease. In conclusion, primary thyroid teratomas are rare and difficult to diagnose preoperatively. In particular, malignant cases are very aggressive tumors with a considerably poor prognosis, even after surgical resection combined with adjuvant chemoradiation.

RESUMO

BACKGROUND: Primary gastric melanoma (PGM) is a rare malignant tumour of the stomach with poor prognosis. The aim of this systematic review was to assess the available literature on this entity and to highlight its biological behaviour and preferred treatment approach. METHODS: PubMed and Cochrane bibliographical databases were independently searched (last search: 2 February 2020) by two investigators for articles reporting on PGM in the adult population. RESULTS: Twenty-five studies met the inclusion criteria and concerned collectively 25 patients (18 males and seven females) with an age of 63.4 ± 8.97 years (mean ± standard deviation). Main symptoms included abdominal pain (64%), weight loss (48%) and hematemesis or melena (32%). The most frequent tumour location was the body of the stomach (54.2%). All tumours were surgically resected and the majority of the patients had a partial gastrectomy (52%). Median recurrence time was 5 months and 12% of patients reached 5-year survival landmark. CONCLUSION: PGM is a rare disease characterized by an aggressive malignant behaviour. Its differential diagnosis from a metastatic lesion is crucial. A prompt diagnosis and therapeutic approach are needed. Further studies are required to elucidate the optimal management of this clinical entity.

RESUMO

Defects in the Canal of Nuck are rare abnormalities of the female genitalia, which are typically detected and repaired in young age. In the present report, a case of a Nuck cyst in a 40-year old female patient is described. Additionally, the current literature concerning cases of women with hydrocele of Nuck canal was systematically reviewed. A total of 16 case reports of 16 patients with Nuck hydrocele (mean age of 35.18 years), have been reported to date. A right inguinal mass was noted in 13 patients (81.3%) whereas in 3 patients a left-sided mass was noted. The surgical approach was open in 13 cases and laparoscopic in 3 cases. Two cases underwent hydrocelectomy and inguinal ring ligation, whereas in 7 cases a simple cystectomy was performed. In 2 cases the round ligament was excised along with the hydrocele. In one of these 2, ligamentum rotundum necrosis and presence of a haemorrhagic cyst of the canal of Nuck were identified. Hernia repair and hydrocelectomy was performed in 5 cases. A cyst of the Canal of Nuck is relatively rare, but should be considered during the diagnosis of inguinal masses in female patients.

RESUMO

PURPOSE: The objective of this review was to evaluate the safety and efficiency of single-incision laparoscopic liver surgery (SILLS) for malignant liver lesions. METHODS: A retrospective review of the Medline database was performed, including studies published up to February 2019. RESULTS: Overall, 69 patients (50 males) with a median age of 61 years (range, 31-90) from 16 studies underwent SILLS for malignant liver disease and were included in this review. The majority of patients underwent resection for hepatocellular carcinoma (n = 52, 75 %), followed by metastatic disease (n = 15, 22 %). The hepatic lesions were located in anterolateral liver segments in 62 patients (90 %) and in posterosuperior liver segments in 7 patients (10 %). Sixty-five patients (94 %) underwent minor liver resection. The median blood loss was 200 mL (range 0-2500), while 4 patients that underwent single-port resection were converted to either conventional laparoscopy or open resections. Two cases were reported to be associated with postoperative complications in the single-port group (1 [1.7 %] grade Dindo-Clavien I-II, 1 [1.7 %] grade Dindo-Clavien III-IV), while no complications were noted in the multiport group. All patients successfully underwent R0 resection. CONCLUSIONS: SILLS seems to be a safe and efficient treatment modality for malignant liver disease when performed by experienced surgeons in carefully selected patients. More studies are needed to better identify which patients may benefit from such an operative approach.

RESUMO

Panniculectomy combined with gynaecological surgery constitutes an alternative approach for endometrial cancer (EC) in obese patients. The present study aimed to assess the current knowledge concerning the safety and efficacy of combining panniculectomy in surgical management of EC. Four electronic databases were systematically searched for articles published up to May 2019. A total of five studies, of which two were non-comparative and three comparative, were included. Meta-analysis of complications among panniculectomy and conventional laparotomy group revealed no difference in either intra- or post-operative complication rates. Moreover, no difference was reported in surgical site complications (p=0.59), while wound breakdown rates were significantly elevated in the laparotomy group (p=0.02). Panniculectomy combined surgery for the management of EC appears to be a safe procedure and results in comparable outcomes compared with conventional laparotomy with regard to complications and improved wound breakdown rates.
