RESUMEN
Cystic echinococcosis is a zoonotic parasitic disease that affects the liver in more than 70% of cases, and there is still an underestimated incidence in endemic areas. With a peculiar clinical presentation that ranges from paucisymptomatic illness to severe and possibly fatal complications, quality imaging and serological studies are required for diagnosis. The mainstay of treatment to date is surgery combined with antiparasitic agents. The surgical armamentarium consists of open and laparoscopic procedures for selected cases with growing confidence in parenchyma-sparing interventions. Endoscopic retrograde cholangiopancreatography (ERCP) is extremely useful for the diagnosis and treatment of biliary fistulas. Recent relevant studies in the literature are reviewed, and two complex cases are presented. The first patient underwent open surgery to treat 11 liver cysts, and during the follow-up, a right pulmonary cyst was diagnosed that was treated by minimally invasive surgery. The second case is represented by the peritoneal rupture of a giant liver cyst in a young woman who underwent laparoscopic surgery. Both patients developed biliary fistulas that were managed by ERCP. Both patients exhibited a non-specific clinical presentation and underwent several surgical procedures combined with antiparasitic agents, highlighting the necessity of customized treatment in order to decrease complications and successfully cure the disease.

BACKGROUND: The suspension of the penis is provided by two ligaments: fundiform and suspensory. These ligaments are sectioned during some augmentative surgical procedures. The structure, the relations and the variability of these ligaments have been demonstrated. The penile neurovascular bundle and its relationships have also been emphasized. A clear knowledge of these details should ensure a reduction of the risk of surgical injury during augmentation procedures. RESULTS: We dissected the ligaments providing the suspension of the penis in 7 formalized corpses. We identified, for each of the ligaments, the origin, the insertion and the relations. The dissection pieces were photographed and the images obtained were discussed upon. We described the variability of the anatomical distribution and highlighted the relations with the vascular and nervous structures for each of these ligaments. The anatomical variability of the fascia and the relations with the base of the penis were also emphasized. For the suspensory ligament, we identified three groups of fibers through which it is attached to the penile body. CONCLUSIONS: The dissections were conducted in layers, corresponding to the operative steps for the penile augmentation procedures. We believe that our study highlights the anatomical basis necessary to safely perform these surgeries. The study contributes to the description of the anatomical variability of the ligaments and logically presents details that contribute to preventing most surgical incidents.
RéSUMé: CONTEXTE: La suspension du pénis est assurée par deux ligaments: fundiforme et suspenseur. Ces ligaments sont sectionnés lors de certaines interventions chirurgicales d'agrandissement pénien. La structure, les relations, et la variabilité de ces ligaments ont été démontrées. Le faisceau neurovasculaire pénien et ses relations ont également été soulignés. Une connaissance claire de ces détails devrait assurer une réduction du risque de blessure chirurgicale pendant les procédures d'augmentation. RéSULTATS: Nous avons disséqué les ligaments assurant la suspension du pénis sur 7 cadavres standardisés. Nous avons identifié, pour chacun des ligaments, l'origine, l'insertion et les relations. Les pièces de dissection ont été photographiées et les images obtenues ont été discutées. Nous avons décrit la variabilité de la distribution anatomique, et mis en évidence les relations avec les structures vasculaires et nerveuses pour chacun de ces ligaments. La variabilité anatomique du fascia et les relations avec la base du pénis ont également été soulignées. Pour le ligament suspenseur, nous avons identifié trois groupes de fibres par lesquelles il est attaché au corps pénien. CONCLUSIONS: Les dissections ont été effectuées en couches, correspondant aux étapes opératoires des procédures d'augmentation du pénis. Nous pensons que notre étude met en évidence la base anatomique nécessaire pour effectuer ces chirurgies en toute sécurité. L'étude contribue à la description de la variabilité anatomique des ligaments et présente logiquement des détails qui contribuent à prévenir la plupart des incidents chirurgicaux.
RESUMEN
BACKGROUND: Since its outbreak in early 2020, the COVID-19 pandemic has diverted resources from non-urgent and elective procedures, leading to diagnosis and treatment delays, with an increased number of neoplasms at advanced stages worldwide. The aims of this study were to quantify the reduction in surgical activity for indeterminate thyroid nodules during the COVID-19 pandemic; and to evaluate whether delays in surgery led to an increased occurrence of aggressive tumours. METHODS: In this retrospective, international, cross-sectional study, centres were invited to participate in June 22, 2022; each centre joining the study was asked to provide data from medical records on all surgical thyroidectomies consecutively performed from Jan 1, 2019, to Dec 31, 2021. Patients with indeterminate thyroid nodules were divided into three groups according to when they underwent surgery: from Jan 1, 2019, to Feb 29, 2020 (global prepandemic phase), from March 1, 2020, to May 31, 2021 (pandemic escalation phase), and from June 1 to Dec 31, 2021 (pandemic decrease phase). The main outcomes were, for each phase, the number of surgeries for indeterminate thyroid nodules, and in patients with a postoperative diagnosis of thyroid cancers, the occurrence of tumours larger than 10 mm, extrathyroidal extension, lymph node metastases, vascular invasion, distant metastases, and tumours at high risk of structural disease recurrence. Univariate analysis was used to compare the probability of aggressive thyroid features between the first and third study phases. The study was registered on ClinicalTrials.gov, NCT05178186. FINDINGS: Data from 157 centres (n=49 countries) on 87 467 patients who underwent surgery for benign and malignant thyroid disease were collected, of whom 22 974 patients (18 052 [78·6%] female patients and 4922 [21·4%] male patients) received surgery for indeterminate thyroid nodules. We observed a significant reduction in surgery for indeterminate thyroid nodules during the pandemic escalation phase (median monthly surgeries per centre, 1·4 [IQR 0·6-3·4]) compared with the prepandemic phase (2·0 [0·9-3·7]; p<0·0001) and pandemic decrease phase (2·3 [1·0-5·0]; p<0·0001). Compared with the prepandemic phase, in the pandemic decrease phase we observed an increased occurrence of thyroid tumours larger than 10 mm (2554 [69·0%] of 3704 vs 1515 [71·5%] of 2119; OR 1·1 [95% CI 1·0-1·3]; p=0·042), lymph node metastases (343 [9·3%] vs 264 [12·5%]; OR 1·4 [1·2-1·7]; p=0·0001), and tumours at high risk of structural disease recurrence (203 [5·7%] of 3584 vs 155 [7·7%] of 2006; OR 1·4 [1·1-1·7]; p=0·0039). INTERPRETATION: Our study suggests that the reduction in surgical activity for indeterminate thyroid nodules during the COVID-19 pandemic period could have led to an increased occurrence of aggressive thyroid tumours. However, other compelling hypotheses, including increased selection of patients with aggressive malignancies during this period, should be considered. We suggest that surgery for indeterminate thyroid nodules should no longer be postponed even in future instances of pandemic escalation. FUNDING: None.

Choledochal cysts (CCs) are rare occurrences presenting as dilatations of biliary structures, which can present as single or multiple dilatations and can appear as both intra- and extrahepatic anomalies. The most widespread classification of CCs is the Todani classification, but there have been numerous reports of cysts that do not fall into any of the types described. We present such a case-a male patient 36 years of age who underwent preoperative CT, MRCP, and ERCP, which mistakenly indicated a type II Todani CC, and intraoperatively was found to be located at the confluence of the hepatic ducts and encompassed the origin of the common bile duct. Complete resection of the cyst and the proximal segment of the common bile duct was performed, and reconstruction was carried out by Roux-en-Y double-tutorized hepaticojejunostomy. Considering the risk of malignant transformation, the frequent preoperative misdiagnosis, as well as the technically challenging surgery required in such cases, we advocate for a revision of the classification and raise awareness of the need for guidelines regarding the proper short-term and long-term management of this disease to ensure adequate quality of life and disease-free survival for patients.
RESUMEN
The modern principles in pelvic surgery imply the preservation of the nervous structures that are involved in the physiological functioning of the pelvic and genital organs. The main pelvic nervous element is represented by the inferior hypogastric plexus. This plexus receives sympathetic afferent fibres from the hypogastric nerve, parasympathetic afferent fibres from the pelvic splanchnic nerves and also sympathetic afferent fibres coming from the sympathetic sacral chain via the sacral splanchnic nerves. We aimed to demonstrate the anatomy of these structures through dissection and we exposed the origins, pathway and manner of distribution of the splanchnic nerves of the pelvis. We managed to clarify the main anatomical relations of these nerves, among which we highlighted the relation to the branches of the internal iliac artery. The parasympathetic fibres reach the pelvis by running through the anterior rami of the spinal nerves, which are the origin of the sacral plexus. We managed to exhibit the way in which the parasympathetic fibres emerge from the sacral nerves and form the pelvic splanchnic nerves. Pelvic surgery nowadays is focused on nerve-sparing, which essentially means the conservation of the integrity of splanchnic nerves, hypogastric nerves and inferior hypogastric plexuses in order to maintain the normal functioning of the anatomical sphincters and genital organs. In this respect, it is crucial for the surgeon who performs pelvic procedures to be more than well-acquainted to the anatomy of the pelvic splanchnic nerves, which are considered to be the erectile nerves, and to that of the sacral splanchnic nerves.
RESUMEN
Elements that comprise the inferior hypogastric plexus are difficult to expose, intricate, and highly variable and can easily be damaged during local surgical procedures. We aimed to highlight, through dissection, the origin, formation, and distribution of the hypogastric nervous structures and follow them in the female pelvis. We performed detailed dissections on 7 female formalin-fixed cadavers, focusing on structures surrounding the pelvic organs. For each hemipelvis, we removed the peritoneum from the pelvic floor, and after we identified the hypogastric nerves, we continued our dissection towards the inferior hypogastric plexuses, following the branches of the latter. Laterorectally, the hypogastric nerves form the inferior hypogastric plexus, a variable structure - nervous lamina, neuronal network (more frequently), or sometimes a combination of them. We identified three components of the inferior hypogastric plexus. The anterior bundle travels towards the base of the urinary bladder, the middle part innervates the uterus and the vagina, and the posterior segment provides the innervation of the rectum. The plexus can be identified after removing the pelvic peritoneum and the subperitoneal adipose tissue. Intraoperatively, the structures can be preserved by using an immediately-subperitoneal dissection plane. The variable branches are relatively well-organized around the pelvic vessels, supplying the urinary bladder, the genital organs, and the rectum. The ureter is surrounded by some branches, especially in its last segment, and it also receives innervation directly from the hypogastric nerve. Close to the viscera, the nerves enter neurovascular plexuses, making the intraoperative separation of the nerves and the vessels virtually impossible.

The pre-lacrimal recess approach is modernly used for lesions of the anterior maxillary wall and for reaching paramedian cranial base regions. In this computed-tomography study, we assessed the pre-lacrimal recess types as well as the angles between the anterior and medial maxillary walls and between the anterior maxillary wall and the lateral margin of the nasolacrimal canal to show the feasibility of the pre-lacrimal recess approach in reaching lesions of the infratemporal and pterygopalatine fossae, using 30 computed-tomography studies (60 sides). A type I pre-lacrimal recess was identified in 22 cases (35%), type II was identified in 31 cases (53.30%), and type III in 7 cases (11.66%). We found that angle 1 (the angle between the anterior maxillary wall and the medial maxillary wall) had a mean value of 80.8° (minimum 75.5°, maximum 85.8°), while angle 2 (the angle between the anterior maxillary wall and the lateral margin of the nasolacrimal canal) had a mean value of 59.1° (minimum 57.6°, maximum 60.1°). We consider the pre-lacrimal recess approach a very good option for the anterior maxillary wall, the alveolar recess, and in reaching the infratemporal fossa and lateral part of the pterygopalatine fossa. In cases where direct visualization of the medial part of the pterygopalatine fossa is needed, the pre-lacrimal recess approach could not be the perfect option.

Despite concerns regarding oncologic safety, laparoscopic surgery for colon cancer has been proven in several trials in the lasts decades to be superior to open surgery. In addition, the benefits of laparoscopic surgery can be offered to other patients with malignant disease. The aim of the present study was to compare the quality of oncologic resection for non-metastatic, resectable colon cancer between laparoscopic and open surgery in terms of specimen margins and retrieved lymph nodes in a medium volume center in Romania. A total of 219 patients underwent surgery for non-metastatic colon cancer between January 2017 and December 2020. Of these, 52 underwent laparoscopic resection, while 167 had open surgery. None of the patients in the laparoscopic group had positive circumferential margins (P=0.035) while 12 (7.19%) patients in the open group (OG) had positive margins. A total of three patients in the laparoscopic group (5.77%) and seven patients (4.19%) in the OG had invaded axial margins. While the number of retrieved lymph nodes was not correlated with the type of procedure [laparoscopic group 16.12 (14±6.56), OG 17.31 (15±8.42), P=0.448], the lymph node ratio was significantly higher in the OG (P=0.003). Given the results of the present study, it is safe to conclude that laparoscopic surgery is not inferior to open surgery for non-metastatic colon cancer in a medium volume center.
RESUMEN
SUMMARY: Background and Objectives: The palatine nerves and vessels cross the pterygopalatine fossa, the palatine canals, the palatine foramina and the submucosal space, at the level of the hard palate and the palatine recess of the maxillary sinus. Their trajectory is long, complicated and difficult to highlight on a single dissection piece. In the literature that we studied, we did not find clear images that fully highlight the real configuration of the pterygopalatine ganglion and nerves and of the palatine vessels. Our aim was to provide a clear and representative dissection of the pterygopalatine ganglion and of the palatine neurovascular bundle throughout its pathway in a simple, coherent and useful presentation for the practitioners interested in the regional pathology. We resected the posterior and inferomedial osseous walls of the maxillary sinus and highlighted the neurovascular structures in the pterygopalatine fossa and the wall of the maxillary sinus. We photographed the dissection fields and detailed the important relations. The images that we obtained are clear, simple and easy to interpret and use. We successfully highlighted the aspect and the main relations of the pterygopalatine ganglion and the pathway and distribution of the palatine nerves and vessels, from their origin to the terminal plexuses. There is a broad spectrum of clinical procedures or situations that require a proper knowledge and understanding of the anatomical pathway and relations of the palatine neurovascular elements. This includes the various types of regional anesthesia, tumor resection surgery, flaps of the palatine mucosa, the LeFort osteotomy etc. Demonstration of the pterygopalatine ganglion and its relations is useful in endoscopic interventions at the level of the pterygopalatine fossa.
RESUMEN: Los nervios y vasos palatinos atraviesan la fosa pterigopalatina, además de los canales palatinos, los forámenes palatinos y el espacio submucoso a nivel del paladar duro y el receso palatino del seno maxilar. Su trayectoria es larga, complicada y difícil de destacar en una sola pieza de disección. En la literatura que estudiamos, no encontramos imágenes claras que resalten completamente la configuración real del ganglio y los nervios pterigopalatinos y de los vasos palatinos. Nuestro objetivo fue proporcionar una disección clara y representativa del ganglio pterigopalatino y del haz neurovascular palatino a lo largo de su trayecto en una presentación simple, coherente y útil para los médicos interesados en la patología regional. Resecamos las paredes óseas posterior e inferomedial del seno maxilar y resaltamos las estructuras neurovasculares en la fosa pterigopalatina y la pared del seno maxilar. Fotografiamos los campos de disección y detallamos las relaciones importantes. Las imágenes que obtuvimos son claras, sencillas y de fácil interpretación. Resaltamos con éxito el aspecto y las principales relaciones del ganglio pterigopalatino y el trayecto y distribución de los nervios y vasos palatinos, desde su origen hasta los plexos terminales. En conclusion, existe un amplio espectro de procedimientos o situaciones clínicas que requieren un adecuado conocimiento y comprensión del trayecto anatómico y las relaciones de los elementos neurovasculares palatinos. Esto incluye los distintos tipos de anestesia regional, cirugía de resección tumoral, colgajos de mucosa palatina, osteotomía de LeFort, etc. La demostración del ganglio pterigopalatino y sus relaciones es útil en intervenciones endoscópicas a nivel de la fosa pterigopalatina.

BACKGROUND: Laparoscopic cholecystectomy in situs inversus totalis (SIT) is a technically and physically demanding procedure for surgeons and there is still a lack of consensus regarding the best technical approach in such cases. We conducted a systematic review and meta-analysis to evaluate port placement, the dominant hand of the surgeon, preoperative imaging, morbidity, and mortality. METHODS: We searched MEDLINE, SCOPUS, Web of Science, and the Cochrane Library for studies of patients with SIT that underwent laparoscopic cholecystectomy. Of 387 identified records, 101 met our inclusion criteria, all of them case reports or case series of maximum of 6 patients. RESULTS: Out of the 121 patients included in the analysis, 94 were operated on using a "mirrored American" technique, 12 using the "Mirrored French", 9 employed single-port techniques, and 6 described novel port placements. Even though most surgeries were conducted by a right-handed surgeon (93 cases), surgeries performed by the seven left-handed surgeons yielded shorter intervention times (p = 0.024). Preoperative imaging (CT, MRI, MRCP, ERCP) also correlated with a lower duration of surgery (p = 0.038. Length of stay was associated with the type of disease, but not with other studied endpoints. Morbidity was less than 1%, and conversion rates and mortality were nil. CONCLUSIONS: Cholecystectomy in SIT is a safe but challenging procedure and surgeons should prepare in advance for the unfamiliar aspects of completing such a task. While preoperative imaging and a left-handed surgeon are beneficial in terms of surgery length, when these are not available surgeons should focus on achieving the most comfortable setting based on their experience and tailor their approach to the patient at hand. Further studies are needed in order to properly describe and evaluate intraoperative findings as well as surgeon-dependent factors that could improve future recommendations.
RESUMEN
The best way to start a paper like this is with a citation from W. Edwards Deming: Without data, you're just another person with an opinion. In the era of Evidence-Based Medicine (EBM) every surgical procedure has to be backed up by solid statistical data to offer our patients the best treatment. But is EBM always the path to truth? We decided to analyze the literature for achalasia and see if the guidelines and the data are reliable enough to justify a certain attitude. Practically, we engaged in this endeavor not because we do not trust the statements of the guidelines, but to see if a surgeon can find by themselves the proper attitude in this disease. Achalasia is a motility disorder of the esophagus characterized by deficient relaxation of the inferior esophageal sphincter that results in dysphagia. There are several methods of treatment, with various statements in the guidelines. Currently, every treatment should be sustained by data and statistics, evidence-based medicine being mandatory when a method is preferred over another. This article reviews several studies and also the available guidelines in search for an answer to the question which procedure is the best.

Anastomotic fistulae are the most common and dreaded postoperative complications of pancreaticoduodenectomy. Delayed gastric emptying (DGE) and slow recovery of bowel function are contributing causes for postoperative pancreatic fistula (PoPF) that should be taken into consideration. The present study evaluates data from 17 consecutive cases that underwent pancreaticoduodenectomy for pancreatic adenocarcinoma with pancreaticojejunal anastomosis and circular stapled mechanical gastrojejunal anastomosis instead of the standard terminolateral technique. Three patients developed Grade A DGE (one also developed grade B PoPF) and one patient required reinsertion of the nasogastric tube due to Grade B PoPF. Overall, the incidence of DGE was 23.5%. Three patients developed Grade B pancreatic fistulae that were successfully managed conservatively. Twelve patients resumed early bowel movement within 4 days, two reinterventions were required for postoperative bleeding. Mean hospital stay was 11.5 days. Patients with DGE had a mean hospital stay of 14.5 days. No gastrojejunostomy leak was encountered. Mortality was nil. Therefore we consider the posterior circular stapled gastrojejunostomy a simple, reproducible, safe technical alternative for avoiding DGE and consequently help lower the risk of PoPF, increased costs associated with prolonged hospital stay and an improved postoperative quality of life.

Takotsubo syndrome is a rare cause of systolic dysfunction and can be found as a clinical manifestation of pheochromocytoma. We present a case of rapid onset of systolic dysfunction with cardiogenic shock, which developed after the surgical excision of an adrenal gland tumor in a 60-year-old male. Coronary angiography excluded coronary artery disease. The echocardiography and ventriculography images suggested Takotsubo cardiomyopathy pattern. Following 2 weeks of inotropic and vasopressor therapy, the left ventricular function gradually improved, until complete resolution.
RESUMEN
Background: Acute cholangitis is a systemic disease caused by acute inflammation and infection of the biliary tree and carries significant morbidity and mortality rates. The most common cause of acute cholangitis is choledocholithiasis, which can lead to an increased death rate in severe forms and in the absence of appropriate treatment. The clinical Charcot's triad is outdated due to low sensitivity and has been replaced with the criteria established by the Tokyo guidelines. The criteria of diagnosis are based on the presence of systemic inflammation, cholestasis and/or jaundice and biliary obstruction documented by imaging studies. Depending on the severity of the disease, treatment varies from antibiotic therapy to emergency endoscopic biliary drainage. In severe cases the first-line treatment is achieved by endoscopic retrograde cholangiopancreatography (ERCP). Method: To evaluate the effectiveness of urgent ERCP treatment in patients with acute cholangitis, a retrospective data analysis was performed of 185 patients that underwent endoscopic interventions between 2018 and September 2020, 74 patients of which have been identified with different grades of acute cholangitis. Results: The studied group consisted of 42 women (56.7%) and 32 men (43.3%), with a mean age of 62.2 (38-93) years. Obstructive choledocholithiasis was as the main cause of cholangitis (44 patients, 59.5%), with varying degrees of severity - grade I (41, 55.4%), grade II (22 patients, 29.7%) and grade III (11 patients, 14.8%). For cases with grade II and III of severity (33 patients, 44.5%), the endoscopic intervention took place in the first 12-24 hours after admission. Patients that had endoscopic dezobstruction in the first 12-24 hours had normal blood tests in 4.7 days (mean) and 5.8 days (mean) of hospital stay while patients that had dezobstruction more than 24 hours after admission had normal blood tests in 6.3 days (mean) and 7.6 days of hospital stay. Mortality was 5.4%, all 4 patients having grade III severity cholangitis. Conclusion: Patients that benefited from endoscopic biliary drainage in the first 24 hours after admission had a faster recovery, decreased duration of antibiotic therapy, decreased duration of hospital stay, lower morbidity and mortality rate compared to those that suffered the intervention more than 24 hours after admission.

Surgical clip migration in the common bile duct with consecutive stone formation is a rare occurrence after laparoscopic cholecystectomy, less than 100 cases being reported so far. We report a case of a 55-year-old woman with obstructive jaundice due to bile duct stone formed around a migrated surgical clip 9 years after laparoscopic cholecystectomy. The patient presented with pain in the upper abdomen and jaundice. Abdominal ultrasound diagnosed dilation of the common bile duct and intrahepatic bile ducts. The diagnosis was confirmed by computed tomography which revealed a metal clip in the distal part of the common bile duct. The patient was managed successfully by endoscopic retrograde cholangiopancreatography (ERCP) and the surgical clip was retrieved using the Dormia basket. The exact mechanism of clip migration is not fully understood but may be explained by local inflammation and ineffective clipping. Although a rare occurrence, clip migration should not be excluded when considering the differential diagnosis of patients presenting with obstructive jaundice or cholangitis after laparoscopic cholecystectomy. Minimally invasive management by ERCP is the procedure of choice for migrated clips related complications but surgical common bile duct exploration may be necessary.

The current concept of complete resection of thyroid parenchyma shifted the practice from subtotal thyroidectomy to total thyroidectomy for a wide range of benign and malignant thyroid affliction and brought the tubercle of Zuckerkandl once again into attention. This embryological remnant has been shown to have a constant relationship with the recurrent laryngeal nerve and the superior parathyroid gland and may be used as a landmark for safe dissection. In order to assess if the presence of the tubercle of Zukerkandl has an impact on the most important complications of thyroid surgery, we have prospectively studied 128 patients diagnosed with nodular goiter who underwent total thyroidectomy. Grade 0 or the absence of the tubercle of Zuckerkandl, according to Pellizo et al, was noted in 42 cases (32.8%). During surgery, we identified 38 grade 1 tubercles (29.7%), 31 grade 2 tubercles (24.2%) and 16 grade 3 tubercles (12.5%). Out of 11 bilateral tubercles, 4 were measured as grade 3.Of all 47 patients with grade 2 and 3 tubercles, 18 (38.3%) developed transient postoperative hypocalcemia (p 0.0001, r=0.47) and 10 (21.3%) transient postoperative nerve palsy (p=0.004, r=0.25). All patients fully recovered during follow-up. The tubercle of Zuckerkandl, when present and of significant macroscopic size is associated with increased rates of transient postoperative hypocalcemia and recurrent laryngeal nerve palsy.

Background: Post-surgical hypoparathyroidism (PoSH) is a common long-term complication after thyroid surgery. The reported median (range) incidence rates of temporary and permanent PoSH was 27% (19 - 38%) and 1% (0 - 3%) respectively. Material and Methods: We retrospectively analyzed the files of 552 patients who underwent thyroidectomy in our surgery department between 2015- 2017 with the aim to assess the prevalence of PoSH and to identify patient and disease related factors associated with postoperative hypocalcemia. Results: 171 (30.97%) patients developed PoSH, 88.37% transient, 11.63% permanent. The median (IQR) duration of postoperative hypocalcemia was 60 (67.5) days. Preoperative biological parameters were similar in PoSH and the control group, except median (IQR) serum magnesium level that was significantly higher in PoSH group [2.04 (0.17) vs. 1.89 (0.28) mg/dl, p=0.005]. In the subgroup of patients with thyroid carcinoma the surgery duration was longer in PoSH patients compared to the control group [135 (60) vs. 110 (43) minutes, p=0.020]. In patients with PoSH, median post-operative serum calcium was significantly higher in patients with reported difficult surgery [8.2 (0.2) vs. 7.9 (0.6) mg/dl, p=0.043] and the mean serum calcium decrease was higher in patients with cervical neck dissection and lymphadenectomy (1.94 +-0.59 vs. 1.68 +-0.56 mg/dl, p=0.033). Conclusions: Our data show a high prevalence of PoSH that is likely to increase given the rising number of thyroid surgeries being performed. Further research is needed in order to better define this condition, to establish appropriate treatment and preventive measures.

Since its first description in 1992, laparoscopic adrenalectomy has become the standard of treatment for most benign and low grade small adrenal tumors but due to the low incidence of adrenal disease, it remains a rarely performed intervention outside referral or excellence centers. Although laparoscopic surgery had a positive impact on complications of adrenalectomy, surgical risk should be thoroughly assessed when it comes to secreting or large tumors. This is a retrospective analysis of laparoscopic adrenalectomies performed in the first 4 years of practice 2007-2010 - the early experience including the learning curve of the senior surgeon, and our late experience from 2016 to 2019. All interventions were performed by a single team led by a senior surgeon with extensive experience in advanced laparoscopic surgery, using the lateral transperitoneal approach. In total, 82 cases were included, out of 153 laparoscopic adrenalectomies performed between 2007 and 2019. Only one conversion was recorded during the early experience and two laparoscopic reinterventions were needed for hemostasis and drainage. Non-secreting adenoma was the most frequent indication for surgery (26 cases) followed by Cushing's Syndrome (22 cases) while adrenocortical carcinoma was diagnosed in 3 cases. Significant differences were found between the two periods regarding operative time and length of postoperative hospital stay (p 0.001). With growing experience in laparoscopic transperitoneal adrenalectomy, less complications and shorter operative time and postoperative hospital stay are to be expected.

Background and objectives: Clostridium difficile infection (CDI) is an important healthcare-associated infection, with important consequences both from a medical and financial point of view, but its correlation with anastomotic leaks after colorectal surgeries is scarcely reported in the literature. Materials and Methods: We conducted a retrospective study looking for patients who underwent open or laparoscopic surgery for colorectal cancers between January 2012 and December 2017, excluding emergency surgeries for complicated colorectal tumors. We also examined patient history for risk factors for CDI such as age, sex, comorbidities, and clinical findings at admission or during hospital stay as well as tumor characteristics. Results: A total of 360 patients were included in the study, out of which 320 underwent surgeries that included anastomoses. There were 19 cases of anastomotic leaks, out of which 13 patients were diagnosed with CDI, with a statistic significance for association between CDI and anastomotic leakage (p < 0.0001). Most patients who developed both CDI and anastomotic leaks had left-sided resections or a type of rectal resection, while none of the patients with right-sided resections had this association, but with no statistical significance possibly due to the limited number of cases. Conclusions: CDI is a relevant risk factor and should be taken into consideration when trying to prevent anastomotic leaks in patients undergoing gastrointestinal surgery for colon or rectal cancer. Thorough assessment of risk factors at admission should be mandatory in order to adequately prepare the patient and plan an optimal course of treatment. Further studies are needed to confirm our findings and a multidisciplinary approach, with a team which should always include the surgeon, is mandatory when it comes to CDI prevention.

Introduction: Complicated colon cancer most frequently presents as obstruction and needs emergency surgery. Most of these patients receive their diagnosis when presenting for complicated disease and by that time the disease is usually advanced. While concerned first with the survival of the patient, the curative intent of the resection following the principles of oncologic resection may come in second place. Materials and methods: We retrospectively analyzed 68 consecutive patients with complicated colon cancer that suffered emergency surgery between January 2017 and September 2018. The principles of oncologic resection were analyzed in terms of resection margins and retrieved lymph nodes and/or multivisceral resections in order to achieve clear margins. Intestinal obstruction was observed in 58 patients (85.3%), perforation was found in 8 patients (11.8%) while lower gastrointestinal bleeding complicated 2 cases (2.9%). Twenty-two patients had distant metastases at presentation, and overall 29 patients (42,6%) had stage IV disease. Clear circumferential margins were achieved in 55 cases while longitudinal margins were found to be invaded in 2 cases and the mean number of retrieved lymph nodes was greater than 13.7. The mean hospital stay was 13.9 days and the observed in hospital mortality was 19.1%. Results: The outcomes of surgery for complicated colon cancer in our department fall within the reported literature results. Conclusion: The principles of oncologic resection in terms of surgical margins and retrieved lymph nodescan be respected during emergency surgery and offer the intent of cure for these patients with advanced disease.
