Pancreatic surgery outcomes: multicentre prospective snapshot study in 67 countries. Br J Surg 2024; 111:znad330. [PMID: 38743040 DOI: 10.1093/bjs/znad330] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2023] [Revised: 08/31/2023] [Accepted: 09/15/2023] [Indexed: 05/16/2024]
Abstract
BACKGROUND Pancreatic surgery remains associated with high morbidity rates. Although postoperative mortality appears to have improved with specialization, the outcomes reported in the literature reflect the activity of highly specialized centres. The aim of this study was to evaluate the outcomes following pancreatic surgery worldwide. METHODS This was an international, prospective, multicentre, cross-sectional snapshot study of consecutive patients undergoing pancreatic operations worldwide in a 3-month interval in 2021. The primary outcome was postoperative mortality within 90 days of surgery. Multivariable logistic regression was used to explore relationships with Human Development Index (HDI) and other parameters. RESULTS A total of 4223 patients from 67 countries were analysed. A complication of any severity was detected in 68.7 per cent of patients (2901 of 4223). Major complication rates (Clavien-Dindo grade at least IIIa) were 24, 18, and 27 per cent, and mortality rates were 10, 5, and 5 per cent in low-to-middle-, high-, and very high-HDI countries respectively. The 90-day postoperative mortality rate was 5.4 per cent (229 of 4223) overall, but was significantly higher in the low-to-middle-HDI group (adjusted OR 2.88, 95 per cent c.i. 1.80 to 4.48). The overall failure-to-rescue rate was 21 per cent; however, it was 41 per cent in low-to-middle- compared with 19 per cent in very high-HDI countries. CONCLUSION Excess mortality in low-to-middle-HDI countries could be attributable to failure to rescue of patients from severe complications. The authors call for a collaborative response from international and regional associations of pancreatic surgeons to address management related to death from postoperative complications to tackle the global disparities in the outcomes of pancreatic surgery (NCT04652271; ISRCTN95140761).

Abstract
PURPOSE Combining cytoreductive surgery (CRS) with Hyperthermic Intraperitoneal Chemotherapy (HIPEC) can benefit patients with peritoneal metastasis from colorectal cancer, however the optimal choice of the HIPEC chemotherapy is still under debate. The present study compares the clinical outcome in patients with peritoneal metastases treated with CRS and HIPEC using Mitomycin - C versus Oxaliplatin. METHODS We retrospectively analyzed patients that underwent CRS and HIPEC for recurrent colorectal cancer with peritoneal metastases. Patient characteristics, procedure details, and clinical outcomes were evaluated. RESULTS 114 consecutive patients were included in the analysis (62 males - 52 females, mean age 58,3 years). The mean intraoperative PCI-score was 15.3 (range: 3 - 36). The mean follow-up period was 28.2 months. Patients receiving MMC - based HIPEC had significantly higher mean overall survival compared to oxaliplatin (54 versus 26 months), translated to a hazard ratio of 0.26 (95% CI 0.128 - 0.529, p<0.01). The HIPEC regimen as well as the completeness of cytoreduction were the only independent prognostic factors of survival in our sample. CONCLUSIONS Our results imply that the use of MMC offers a survival advantage over oxaliplatin when used for HIPEC in CRC PC. A randomised trial comparing oxaliplatin and MMC would enhance decision-making in such patients.

Background
The magnitude of myocardial damage after acute ST-elevation myocardial infarction (STEMI) is a crucial prognostic determinant. Cardiac magnetic resonance (CMR) imaging offers a precise infarct severity assessment after STEMI; however, limited to restricted availability in daily clinical routine. Recently, a simple ECG score (DETERMINE score) was developed for infarct size (IS) estimation in STEMI patients with prior infarction. We sought to validate this score in patients with first-time STEMI for the assessment of myocardial injury visualized by CMR.
Methods
In this validation study, 423 revascularized first-time STEMI patients (median age 56, 17% women) were included. ECG was conducted at discharge for evaluation of the DETERMINE and Selvester score. CMR imaging was performed at a median of 3 days for the assessment of infarct characteristics (IS and microvascular obstruction [MVO]).
Results
Median DETERMINE score of the overall cohort was 8 points (interquartile range: 5-11). Patients presenting with a score > 8 points had more often anterior infarct localization (64% vs. 29%, p < 0.001) and higher peak hs-TnT levels (6957 ng/l vs. 3117 ng/l, p < 0.001). In linear and binary multivariable logistic regression analysis, the DETERMINE score remained as independent associate of IS (odds ratio [OR]: 1.09, 95% confidence interval [CI] 1.00 to 1.18, p = 0.047) and MVO (OR: 1.09, 95% CI 1.02 to 1.16, p = 0.016), after adjustment for Selvester score and peak hs-cTnT.
Conclusions
In survivors of first-time STEMI, the DETERMINE score provides an easy and inexpensive tool for suitable IS estimation. Moreover, the DETERMINE score showed significant and independent association with MVO. Thus, this simple ECG score might help identify patients at high risk of large infarct burden who might benefit from more aggressive treatment strategies.

Global variation in postoperative mortality and complications after cancer surgery: a multicentre, prospective cohort study in 82 countries. Lancet 2021; 397:387-397. [PMID: 33485461 PMCID: PMC7846817 DOI: 10.1016/s0140-6736(21)00001-5] [Citation(s) in RCA: 104] [Impact Index Per Article: 34.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2020] [Revised: 12/02/2020] [Accepted: 12/17/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND 80% of individuals with cancer will require a surgical procedure, yet little comparative data exist on early outcomes in low-income and middle-income countries (LMICs). We compared postoperative outcomes in breast, colorectal, and gastric cancer surgery in hospitals worldwide, focusing on the effect of disease stage and complications on postoperative mortality. METHODS This was a multicentre, international prospective cohort study of consecutive adult patients undergoing surgery for primary breast, colorectal, or gastric cancer requiring a skin incision done under general or neuraxial anaesthesia. The primary outcome was death or major complication within 30 days of surgery. Multilevel logistic regression determined relationships within three-level nested models of patients within hospitals and countries. Hospital-level infrastructure effects were explored with three-way mediation analyses. This study was registered with ClinicalTrials.gov, NCT03471494. FINDINGS Between April 1, 2018, and Jan 31, 2019, we enrolled 15 958 patients from 428 hospitals in 82 countries (high income 9106 patients, 31 countries; upper-middle income 2721 patients, 23 countries; or lower-middle income 4131 patients, 28 countries). Patients in LMICs presented with more advanced disease compared with patients in high-income countries. 30-day mortality was higher for gastric cancer in low-income or lower-middle-income countries (adjusted odds ratio 3·72, 95% CI 1·70-8·16) and for colorectal cancer in low-income or lower-middle-income countries (4·59, 2·39-8·80) and upper-middle-income countries (2·06, 1·11-3·83). No difference in 30-day mortality was seen in breast cancer. The proportion of patients who died after a major complication was greatest in low-income or lower-middle-income countries (6·15, 3·26-11·59) and upper-middle-income countries (3·89, 2·08-7·29). Postoperative death after complications was partly explained by patient factors (60%) and partly by hospital or country (40%). The absence of consistently available postoperative care facilities was associated with seven to 10 more deaths per 100 major complications in LMICs. Cancer stage alone explained little of the early variation in mortality or postoperative complications. INTERPRETATION Higher levels of mortality after cancer surgery in LMICs was not fully explained by later presentation of disease. The capacity to rescue patients from surgical complications is a tangible opportunity for meaningful intervention. Early death after cancer surgery might be reduced by policies focusing on strengthening perioperative care systems to detect and intervene in common complications.

A novel way of hook wire placement for surgical resection of suspicious breast lesions using the stereotactic vacuum assisted breast biopsy table. Breast J 2021; 27:403-405. [PMID: 33480090 DOI: 10.1111/tbj.14164] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2021] [Revised: 01/07/2021] [Accepted: 01/08/2021] [Indexed: 11/28/2022]
Abstract
Preoperative hook localization is a necessary procedure for targeting impalpable breast lesions. The aim of the current study is to introduce an alternative technique of wire placement by using the stereotactic biopsy device instead of the conventionally used mammography device. Fifty-one patients with impalpable mammographic lesions, graded BIRADS 4 or 5, were prospectively enrolled. Mean duration was 7 ± 1.5 minutes. Lesion-to-wire distance was <1 cm in 96% (51/53). Hook wire placement using the stereotactic biopsy device is considered as a safe, accurate, fast, and well-tolerable for the patient procedure.

Abstract
Giant phyllodes tumors are rare fibroepithelial breast neoplasms typically >10 cm by definition. The best investigation for preoperative diagnosis is core biopsy, although it is often difficult for the pathologist to distinguish fibroadenomas from phyllodes tumors and determine the level of malignant potential. The wide excision is the appropriate therapy for phyllodes tumors taking into consideration that mastectomy may be required for huge phyllodes tumors. In the modern era of breast tissue expanders and breast implants, immediate breast reconstruction is feasible. We present a case report of a patient with a giant phyllodes tumor of 24 cm diameter who underwent mastectomy and immediate breast reconstruction with breast tissue expander.

Abstract
Background Combining cytoreductive surgery (CRS) with Hyperthermic IntraPeritoneal Chemotherapy (HIPEC) can benefit patients with peritoneal metastasis from colorectal cancer. The present study evaluates the small bowel subset of the Peritoneal Cancer Index (Small-Bowel-PCI score (SB-PCI), min-max 0–12) as a prognostic factor in such patients. Methods We retrospectively analyzed patients that underwent CRS and HIPEC for recurrent colorectal cancer with peritoneal metastasis. Patient characteristics, procedure details, and clinical outcomes were evaluated. Results Eighty patients were included. The mean intraoperative PCI-score was 16.8, with a mean SB-PCI score of 5.9. CC0/1 was achieved in 62/80 patients. The mean follow-up period was 26.3 months. Univariate regression analysis showed that the ECOG status, the presence of severe complications, the HIPEC regimen (oxaliplatin vs. mitomycin-C), the PCI score, the SB-PCI score and the completeness of cytoreduction correlated significantly with overall survival. In multivariate analysis, the SB-PCI and CC score were identified as independent prognostic factors of survival. When the SB-PCI was stratified in three groups (0–4, 5–8 and 9–12), Kaplan–Meier curve analysis showed significant difference in survival (p<0.001). Conclusions The SB-PCI correlates with overall survival in patients with peritoneal metastases secondary to colorectal cancer in this retrospective cohort. Its use should be validated in prospective patient series.

Abstract
PURPOSE The endothelin system is involved in the evolution of multiple malignancies, participating in cancer cell proliferation, tumor invasion and angiogenesis. Our purpose was to simultaneously assess endothelin expression in the systemic circulation of patients with lobular neoplasia (LN) of the breast and to investigate its correlation with vascular endothelial growth factor (VEGF) specimen expression levels as well as clinicopathologic findings. METHODS This was a retrospective analysis of prospectively collected data regarding 60 women examined in a single breast unit. Thirty of these women underwent stereotactic biopsy and were diagnosed with LN and the remaining 30 were healthy controls. Circulating levels of endothelin (ET)-1 and Big ET-1 were measured using ELISA, while tissue expression of ET-1 and VEGF in biopsy specimens were assessed using qualitative immunohistochemical staining. RESULTS The plasma levels of Big ET-1 were significantly increased in patients with LN compared to healthy controls. There was no significant difference in the plasma levels of ET-1 between the patient groups. In patients with LN, plasma expression of ET-1 and Big ET-1 did not correlate with ET-1 or VEGF tissue expression status, neither existed a relationship between tissue expressions of ET-1 and VEGF. CONCLUSIONS Our results imply that Big ET-1 is a potential biomarker for LN. Further investigation of the endothelin system role in LN seems a promising research field.

Abstract
Massive localized lymphedema (MLL) constitutes a rare benign clinical disorder, presenting in obese patients, characterized by chronic accumulation of lymph and adipose tissue due to lymphatic flow obstruction. MLL may mimic an abundance of soft tissue tumors. Nevertheless, surgical excision of the soft-tissue mass, seems the most favorable therapeutic approach, as performed in the presented case.
Introduction: Ectopic parathyroid glands occur in 6–16% of cases of PHPT and they constitute a potential cause of failed primary surgical therapy. In particular, aberrant adenomas located deeper in the mediastinum, as in the presented case, remain a severe challenge for the surgeons. Presentation of case: A 54-year-old Caucasian female proceeded to our institution with signs and symptoms of PHPT. Imaging studies performed identified a large mass localized in the lower anterior mediastinum, on the left of the median line. A mid-sternal thoracotomy was performed and the aberrant adenoma was finally detected anterior to the pericardium and the left pericardiophrenic vessels and the left phrenic nerve. The operation was uneventful. A meticulous review of the literature was conducted as well. Discussion: Single parathyroid adenomas are the key culprits of PHPT. Anatomic aberrations of the location of the parathyroid glands and their adenomas are more common than described in the literature and there are possible anatomic aberrations that have not been described yet. All these anatomic variations constitute major risk-factors of thoracic bleeding and of nerve injury. Conclusion: Detailed preoperative detection in addition to meticulous exposure of the operative field are fundamental in order to perform a safe adenoma excision without harmful impacts to the patient.

Abstract
Superior mesenteric artery (SMA) or Wilkie’s syndrome is a rare clinical entity of partial or complete duodenal obstruction. The pathogenic mechanism is an acute angulation of the SMA which leads to compression of the third part of the duodenum between the SMA and the aorta. This is commonly due to loss of fatty tissue as a result of a variety of debilitating conditions. Its treatment is initially conservative and in case of failure, surgical therapy is unavoidable. We present a case of a 68-year-old female patient who presented in our Department with symptoms of dehydration after persistent vomiting for months. After complete radiologic workup, SMA syndrome was diagnosed and was successfully treated operatively. SMA syndrome might be a diagnostic challenge and must be always included in the differential diagnosis of upper gastrointestinal obstruction. Consequently, this paper aims to increase the awareness of a rare entity of duodenal obstruction.

Abstract
Background Current treatment options for achalasia of the esophagus predominantly consist of endoscopic myotomy or laparoscopic myotomy combined with a partial fundoplication. The intraoperative use of conventional manometry has previously been proposed with various results. The aim of the present study was to introduce the use of high-resolution manometry (HRM) during surgical treatment for achalasia and to assess the long-term outcome of this technique. Methods We enrolled achalasia patients within the time period November 2013 to July 2016 who underwent HRM and evaluation of Eckardt scores (ES) before and after tailored laparoscopic myotomy and fundoplication with intraoperative recording using HRM. Results Twenty patients were classified as having achalasia type I (20%), type II (55%), or type III (25%). During surgery, 9 myotomies were extended and 13 fundoplications were modified according to HRM findings. Mean resting (16.1 vs. 41.9 mmHg) and residual (9 vs. 28.7 mmHg) pressures of the lower esophageal sphincter and ES (0.7 vs. 6.9) were significantly eliminated postoperatively over a mean follow-up time of 17.7 months. Conclusions The use of intraoperative HRM gives us the advantage of simultaneous real-time estimation of intraluminal pressures of the esophagus and the ability to identify the exact points that produce pressure during laparoscopy. Consequently, it may be the key to the tailoring of the Heller-Dor technique and improving the outcomes for achalasia patients.

Abstract
Complete duplication of ureters is a very rare clinical entity that may either be asymptomatic or present with a variety of clinical findings. In the presented case a 51-year-old Caucasian female underwent an intersphincteric resection for low rectal cancer. Intraoperatively, during the standard bilateral recognition and mobilization of the ureters, complete unilateral duplication of the left ureter was incidentally detected, deriving from a single renal parenchyma. Such a congenital abnormality though constitutes a major risk-factor of accidental ureteral injury during operations including pelvis. Conclusively, meticulous exposure of both ureters combined with surgeons’ unceasing awareness constitute the cornerstone of a safe operation.

Gastrointestinal schwannomas: a rare but important differential diagnosis of mesenchymal tumors of gastrointestinal tract. BMC Surg 2018; 18:47.

Abstract
BACKGROUND Schwannomas of gastrointestinal tract are rare, mostly benign and notably different neoplasms from conventional schwannomas that arise in soft tissue or the central nervous system. These tumors are of clinical importance since they should always be considered in the differential diagnosis of submucosal lesions of gastrointestinal tract. METHODS Seven patients with a pathologically proven gastrointestinal schwannoma were identified in our series of mesenchymal tumors and reviewed retrospectively. Clinicopathological and immunohistochemical parameters along with the follow-up results were analysed. RESULTS The series included two males and five females, with a mean age 69 years (range, 39-81). Most patients were asymptomatic on presentation, except for two patients with abdominal pain. In the other cases (n = 5), the tumor was an incidental finding during other medical, imaging or surgical procedures. The tumors were located in the stomach (n = 4) and in the small intestine (n = 3) with an average size of 29 mm (range, 12-70). A preoperative diagnosis was achieved only in one case with a CT-guided core biopsy. Otherwise the clinical, intraoperative, endoscopic or radiological findings were unspecific. Patients with gastric tumor underwent either laparoscopic (n = 2) or open (n = 2) gastric wedge resection of the tumor; in the cases of intestinal tumor (n = 3) a segmentectomy was performed. Pathological examination revealed solid homogenous tumors, which were highly cellular and composed of spindle cells with positive staining for S100 protein, and confirmed the diagnosis of schwannoma. All tumors were negative for c-Kit, smooth muscle actin, desmin and DOG-1 and showed very low proliferation index. There were negative resection margins and no malignant variants were recognized. At an average follow-up of 60 months (range, 24-185) all patients were free of disease with no signs of recurrence or metastases and acceptable gastrointestinal function. CONCLUSIONS Schwannomas are rare, slow-growing and mostly asymptomatic gastrointestinal mesenchymal tumors. They are difficult to be diagnosed preoperatively as endoscopic and radiological findings are nonspecific but histological and immunohistochemical features are of paramount importance to differentiate between benign and malignant schwannomas, or other spindle cell sarcomas. The treatment of choice is complete surgical excision without a conclusive preoperative diagnosis, and the long-term outcome is excellent as these lesions are mostly benign.

Surgical site infection after gastrointestinal surgery in high-income, middle-income, and low-income countries: a prospective, international, multicentre cohort study. THE LANCET. INFECTIOUS DISEASES 2018; 18:516-525. [PMID: 29452941 PMCID: PMC5910057 DOI: 10.1016/s1473-3099(18)30101-4] [Citation(s) in RCA: 236] [Impact Index Per Article: 39.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/14/2017] [Revised: 12/06/2017] [Accepted: 12/15/2017] [Indexed: 02/07/2023]
Abstract
BACKGROUND Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world. METHODS This international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231. FINDINGS Between Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58·5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31·2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10·2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12·3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9·4%] of 7339 patients), middle (549 [14·0%] of 3918 patients), and low (298 [23·2%] of 1282) HDI (p<0·001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17·8%] of 574 patients in high-HDI countries; 74 [31·4%] of 236 patients in middle-HDI countries; 72 [39·8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1·60, 95% credible interval 1·05-2·37; p=0·030). 132 (21·6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16·6%) of 295 patients in high-HDI countries, in 37 (19·8%) of 187 patients in middle-HDI countries, and in 46 (35·9%) of 128 patients in low-HDI countries (p<0·001). INTERPRETATION Countries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication.

Abnormal distance of the extralaryngeal bifurcation point of the recurrent laryngeal nerve from the cricothyroid joint. J Surg Case Rep 2018; 2018:rjx257. [PMID: 29383239 PMCID: PMC5786220 DOI: 10.1093/jscr/rjx257] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2017] [Revised: 11/24/2017] [Accepted: 12/18/2017] [Indexed: 11/26/2022] Open
Abstract
The extralaryngeal bifurcation point of the recurrent laryngeal nerve (RLN) is typically located in a mean distance of 0–2 cm from the cricothyroid joint (CTJ). In the presented case though, the left RLN was unexpectedly identified bifurcating in a mean distance of 7 cm from the left CTJ in a young woman with multinodular goiter during total thyroidectomy. The RLN was carefully exposed throughout its course for the avoidance of iatrogenic injury of the nerval structure. The operation was uneventful. The present manuscript aims to highlight a scarce anatomic variation and its implications for thyroidectomy. Rare anatomic variations of the RLN such as the presented one encumber thyroid surgery and represent a severe risk factor of RLN injury. Meticulous operative technique combined with surgeons’ perpetual awareness concerning this peculiar anatomical aberration leads to an injury-free thyroid surgery.

Abstract
The facial nerve (FN) and the retromandibular vein (RMV) are anatomical structures in close proximity. Anatomic variations of their relationship complicate parotid surgery and increase the potentiality of nerve injury or bleeding. The true prevalence of such kind of variations seems to be underestimated, since the literature is restricted. Novel variations of the relationship of the FN with the RMV are probable. Therefore, surgeons’ knowledge and perpetual awareness are fundamental and essential in order to perform safe parotid surgery.
Introduction Identification and preservation of the facial nerve (FN) is a major challenge when performing parotidectomy. Anatomic variations of the relation between the FN and the retromandibular vein (RMV) pose a high risk of nerve injury and bleeding during the operation. Presentation of case An unusual anatomic variation of the relation between the FN and the RMV was unexpectedly detected during superficial parotidectomy. The operation was uneventful. A meticulous review of the recent literature was conducted as well. Discussion Variations of the relation between the FN and the RMV are mainly identified during the operation, since when performing parotidectomy, surgeons typically detect all the FN branches by locating the RMV. Such kind of variations, are not as rare as considered and their presence complicates parotid surgery and increases the potentiality of nerve injury and hemorrhage. Conclusion Surgeons’ deep knowledge and perpetual awareness concerning the probable anatomic variations of the relation between the FN and the RMV combined with detailed exposure of the operative field and of the relationship between these adjacent anatomical structures lead to safe parotid surgery.

Abstract
PURPOSE The combination of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has been used as locoregional treatment in selected patients with peritoneal malignancy. The purpose of this study was to report on the outcomes of patients undergoing hepatobiliary and pancreatic procedures during CRS and HIPEC. METHODS A prospectively maintained database was used to identify patients that underwent hepatobilliary and/or pancreatic procedures during CRS and HIPEC. Outcome variables included morbidity, 30-day or in-hospital mortality, return to operating theatre, and complications. RESULTS Sixty eight patients were included in the study, in whom 67 hepatobiliary and 15 pancreatic procedures were performed. Complete cytoreduction (CC-0/1) was achieved in 64 patients (94.8%). Twelve patients underwent liver resections, 50 underwent resection of Glisson's capsule, 5 underwent procedures of the biliary tree and 15 patients underwent pancreatic procedures. Major complications were encountered in 30/68 patients (44.1%). Pancreatic fistulas (PFs) were observed in 42.8% of the patients that underwent distal pancreatectomy. Reoperation rate was 8.8%, while 2.9% of the patients died during their hospital stay. CONCLUSION The need for hepatobiliary procedures bears a significant - but acceptable - rate of morbidity. However, it should not represent a definitive contraindication for CRS and HIPEC.

Abstract
Langer's axillary arch is usually asymptomatic and difficult to detect preoperatively. When present, it is important for surgeons operating in the axillary region, to identify correctly the relevant anatomy. Simple surgical division is curative and necessary in order to achieve exposure of the axillary contents, lymphatic dissection, and neurovascular preservation.

Abstract
Cytoreductive surgery (CRS) and Hyperthermic Intraperitoneal Chemotherapy (HIPEC) is increasingly used in the treatment of peritoneal malignancies. The administration of HIPEC after complete cytoreduction offers the combination of the pharmacokinetic advantages inherent to the intraperitoneal delivery of cytotoxic chemotherapy, with the direct cytotoxic effects of hyperthermia, and has been reported to offer significantly improved patient outcomes. As a result, this novel method disseminates rapidly, with many surgical teams having developed peritoneal malignancy treatment programs. Protocols are needed for the introduction, handling, and management of chemotherapeutic agents in the operating room to minimize risk to the staff involved in the procedure. The personnel exposure during CRS and HIPEC may arise from different routes, such as air contamination, direct contact, manipulation of perfusates or chemotherapy solutions, and manipulation of objects/tissues exposed to chemotherapeutics. Guidelines for safe administration of HIPEC including environmental contamination risk management, personal protective equipment, and occupational health issues are yet to be established. This review summarizes the existing evidence regarding the safety considerations of HIPEC administration.

Abstract
BACKGROUND Stereotactic vacuum assisted breast biopsy (VABB) procedures remain of key importance in the diagnostic evaluation of suspicious non-palpable mammographic lesions. The Breast Lesion Excision System(®) (BLES) is an image-guided percutaneous biopsy method that utilizes radiofrequency (RF) in order to retrieve an intact-tissue biopsy specimen. The purpose of this study is to determine the effects of RF application on the tissue specimen and the possible interference with the histopathologic results. METHODS In this study we included 265 patients with suspicious non-palpable mammographic lesions who underwent 273 stereotactic VABB procedures using the BLES. All biopsies were performed by the same surgical-radiology team under local anesthesia. The specimen thermal damage was classified according to the pathology report in 3 categories: Severe (extensive thermal damage or inability to diagnose), medium (ability to diagnose but either circumferential damage >1.5 mm or diffuse areas of thermal damage) and mild (circumferential thermal damage <1.5 mm but >0.5 mm). RESULTS Radiofrequency-associated thermal damage of the specimen was observed in 14 cases (5.13 %), and was classified as severe in 5, medium in 5, and mild in 4 specimens. Within the group of RF damaged specimens, we found a significant (p < 0.05) positive correlation between fat cell content and classification of thermal damage. CONCLUSIONS Although thermal damage is of concern during BLES breast biopsy, the incidence is low, and the outcome of the histopathologic assessment is not affected even in severely damaged specimens. Increased thermal damage seems to correlate with higher fat cell content of the specimen.

Markers of stem cells in human ovarian granulosa cells: is there a clinical significance in ART? J Ovarian Res 2012; 5:36.

Abstract
Background The purpose of the study was to determine the incidence of gene expression of Oct-4 and DAZL, which are typical markers for stem cells, in human granulosa cells during ovarian stimulation in women with normal FSH levels undergoing IVF or ICSI and to discover any clinical significance of such expression in ART. Methods Twenty one women underwent ovulation induction for IVF or ICSI and ET with standard GnRH analogue-recombinant FSH protocol. Infertility causes were male and tubal factor. Cumulus–mature oocyte complexes were denuded separately and granulosa cells were analyzed for each patient separately using quantitative reverse-transcription–polymerase chain reaction analysis for Oct-4 and DAZL gene expression with G6PD gene as internal standard. Results G6PD and Oct-4 mRNA was detected in the granulosa cells in 47.6% (10/21). The median of Oct-4 mRNA/G6PD mRNA was 1.75 with intra-quarteral range from 0.10 to 98.21. The OCT-4 mRNA expression was statistically significantly correlated with the number of oocytes retrieved; when the Oct-4 mRNA expression was higher, then more than six oocytes were retrieved (p=0.037, Wilcoxon rank-sum). No detection of DAZL mRNA was found in granulosa cells. There was no additional statistically significant correlation between the levels of Oct-4 expression and FSH basal levels or estradiol peak levels or dosage of FSH for ovulation induction. No association was found between the presence or absence of Oct-4 mRNA expression in granulosa cells and ovarian response to gonadotropin stimulation. Also, no influence on pregnancy was observed between the presence or absence of Oct-4 mRNA expression in granulosa cells or to its expression levels accordingly. Conclusions Expression of OCT-4 mRNA, which is a typical stem cell marker and absence of expression of DAZL mRNA, which is a typical germ cell marker, suggest that a subpopulation of luteinized granulosa cells in healthy ovarian follicles (47.6%) consists of stem cells, which are not originated from primordial germ cells. Absence of Oct-4 gene expression in more than half of the cases means probably the end of the productive journey of these cells, towards the oocyte.

Abstract
PURPOSE Introduction of stapled hemorrhoidopexy (SH) brought a radical change in the treatment of haemorrhoidal disease. The aim of this study is to evaluate the results and the complications (early and late) from the use of this technique. METHODS During the last 6 years (2005-2011), 123 patients underwent a SH in our ward. Our sample consists of 79 male and 44 female patients with an average age of 48.2 years (range 22-83 years). Of them, 83 had third-degree haemorrhoidal disease, 34 had fourth-degree and 6 had second-degree bleeding haemorrhoids. The follow-up period was 6-72 months. RESULTS Pain was minimal or even not existent. Additional sutures or use of adrenaline 1:200.000 for haemostasis were required in 6 patients (4.8%). The bleeding has been diminished with the use of this new haemorrhoidectomy stapler PPH03. Urinary retention, which was observed in 3 patients (2.4%), was temporary and the use of catheter was not needed. As a late complication, 'faecal urgency' occurred in 8 patients (6.5%), and disappeared after some months. No recurrent haemorrhoidal disease occurred. No cases of chronic pain were reported. Average hospital stay was 1 day, except for 2 patients who remained for 2 days for bleeding observation. CONCLUSIONS The correct application of SH reduces the possible complications. The advantages of the stapled procedure are reduced postoperative pain, the minimal hospital stay and early return to work.

Abstract
INTRODUCTION The presence of the appendix in a femoral hernia sac is known as de Garengeot's hernia. We report a rare case of an elderly woman with femoral hernia appendicitis and discuss the surgical pitfalls and considerations through a literature review. PRESENTATION OF CASE An 83-year-old woman presented with fever and right lower quadrant abdominal pain. Clinical examination revealed a femoral hernia. Ultrasonography confirmed bowel was present in the hernia sac. In the operation room, an acutely inflamed appendix was recognized within the sac. The patient underwent appendectomy and hernia repair with sutures. DISCUSSION Acute appendicitis within a femoral hernia is rare and multiple dilemmas exist regarding its treatment. An incision below the inguinal ligament is a reasonable choice in order to access the hernia sac. A mesh should be placed in non-infectious appendectomy while herniorrhaphy is preferred in cases of appendicitis. CONCLUSION The presence of the vermiform appendix in a femoral hernia sac is rare but the surgeon should be aware of this clinical entity. Prompt diagnosis and appropriate surgical treatment is the key to avoid complications.

Abstract
BACKGROUND Digit ratios, such as the second to fourth digit ratio (2D:4D), are biometric markers that are influenced by estrogen and testosterone concentrations in utero and are determined genetically by HOX genes (homeodomain-containing homeotic genes). Sex steroids also play a crucial role in the occurrence of myocardial infarction (MI), which is considered to be gender dependent and related to testosterone. Additionally, first-trimester exposure to excess levels of estrogens and progesterone has been linked to cardiovascular anomalies. OBJECTIVE The aim of this work was to study digit ratios in a Greek population and assess their clinical importance as markers of predisposition to MI. METHODS Two samples were used: a group of Greek men and women hospitalized with MI, and a control group of healthy Greek men and women of the same age. Finger lengths were measured twice for both hands using electronic calipers. In the results, digits were designated as 2D (second digit), 3D (third digit), 4D (fourth digit), and 5D (fifth digit). RESULTS A total of 50 Greek men and 50 Greek women with MI were recruited (mean [SD] age, 69.3 [11.2] years for men; 69.7 [11.0] years for women). The control group consisted of 40 healthy Greek men and 40 healthy Greek women (mean age, 68.0 [11.8] years for men; 66.8 [10.7] years for women). In the control group, 2D:4D, 2D:3D, and 2D:5D ratios were significantly higher in women than in men (2D:4D: right hand, P < 0.001; left hand, P = 0.002; 2D:3D: right hand, P < 0.001; left hand, P = 0.003; 2D:5D: right hand, P < 0.001; left hand, P < 0.05). The mean values of 2D:4D ratios appeared to increase in the following order: healthy men < men with MI < healthy women < women with MI, although this difference was not statistically significant. In men with MI, 2D:4D and 3D:4D ratios were significantly higher than the respective ratios in healthy men (2D:4D: right hand, P = 0.001; left hand, P < 0.05; 3D:4D: right hand, P < 0.05; left hand, P = 0.001), but no significant differences were observed in the ratios between women with MI and healthy women. CONCLUSIONS Digit ratios that include ring-finger length (ie, 4D) may be useful biomarkers for predisposition to MI in Greek men, but not in Greek women. Sexual dimorphism of digit ratios was present in both groups and was independent of the individuals' health status.
