Hepatocellular carcinoma (HCC) is the sixth most common cancer. Spontaneous rupture of HCC is an acute complication with a high mortality rate. The HCC principally arises in the background of chronic liver disease and cirrhosis of the liver. In the last few years, the rising incidence of HCC in noncirrhotic liver suggests the presence of other factors that may play a role in liver carcinogenesis.

Retrograde approach (“fundus first”) is often used in open surgery, while in laparoscopic cholecystectomy (LC) is less frequent. LC, with antegrade access, is done by putting in traction the infundibulum and going up to the fundus before to clip the cystic. Our study analyzes a number of surgical procedures performed by experienced surgeons in laparoscopy.

The Ca2+-binding protein sorcin regulates intracellular calcium homeostasis and plays a role in the induction of drug resistance in human cancers. Recently, an 18 kDa mitochondrial isoform of sorcin was reported to participate in antiapoptosis in human colorectal cancer (CRC), but information remains lacking about the functional role of the more abundant 22 kDa isoform of sorcin expressed in CRC. We found the 22 kDa isoform to be widely expressed in human CRC cells, whether or not they were drug resistant. Its upregulation in drugsensitive cells induced resistance to 5-fluorouracil, oxaliplatin, and irinotecan, whereas its downregulation sensitized CRC cells to these chemotherapeutic agents. Sorcin enhances the accumulation of Ca2+ in the endoplasmic reticulum (ER), preventing ER stress, and, in support of this function, we found that the 22 kDa isoform of sorcin was upregulated under conditions of ER stress. In contrast, RNAi-mediated silencing of sorcin activated caspase-3, caspase-12, and GRP78/BiP, triggering apoptosis through the mitochondrial pathway. Our findings establish that CRC cells overexpress sorcin as an adaptive mechanism to prevent ER stress and escape apoptosis triggered by chemotherapeutic agents, prompting its further investigation as a novel molecular target to overcome MDR.

Introduction: Primary Hyperparathyroidism (PHPT) is a systemic pathology caused by an excessive secretion of parathyroid hormone. Parathyroidectomy is the treatment of choice in PHPT, and the success of surgery is based on precise localization of the abnormal parathyroid gland. Preoperative diagnosis makes use of imaging techniques and functional examinations, however these are insufficient in some cases for the precise location of the pathological gland. Therefore the need arises for an intraoperative localization technique., Materials and Methods: We have retrospectively analyzed 20 consecutive patients with PHPT undergoing parathyroidectomy from April 2019 to September 2021, and divided them in two groups, in base of the use of Indocyanine Green (ICG) fluorescence during the surgery., Results: Of the twenty patients considered in the two groups, all received a preoperative ultrasound evaluation, while second level examinations were reserved for the more difficult cases, with small volume parathyroid adenomas. In the group where the fluorescence method was employed, fluorescence was especially useful in doubtful cases, allowing easier identification of the parathyroid adenoma and consequently a reduction of time and operatory risks. In two procedures using Indocyanine green, a fluorescence signal was weak., Conclusions: ICG represents a convenient and safe way to detect parathyroid adenomas. We found that ICG fluorescence was very useful in all patients with non-localizing preoperative imaging studies. However further investigation is needed, to demonstrate how ICGfluorescence could be a useful localization method during parathyroid surgery., Key Words: Endocrine surgery, Indocyanine green, Parathyroid surgery.

Introduction: The improvement of surgical procedures and oncological outcomes in the treatment of low-ultralow rectal cancer, made important the evaluation of functional results. The aim of this study is to evaluate the functional results after open and laparoscopic approach., Patients and Methods: From our global experience, over the period 2000/2018, within the patients surgically treated for rectal cancer, we have gathered and studied 37 patients with low-ultralow site of lesion, submitted to sphincterpreserving surgery, subdivided based on the approach: 20 open, 17 laparoscopic, of which 8 robotic . For each type of procedure, as low and ultralow anterior resection, intersphinteric resection, abdominoperineal resection, were investigated functional outcomes, as bowel continence, urinary functions, male and female sexual functions, based on the following tests: Wexner Incontinence Score, International Prostatic Symptom Score, International Index of Erectile Function- 5, Female Sexual Function Index. The controls were performed before surgery and 3-6-12 months postoperatively. Statistical analisis: X2-test, impaired and paired t-test two tailed, Bonferroni post-hoctest., Results: The immediate surgical results and pathological features of the tumor are reported and evaluated. The evaluation of fecal continence in all patients submitted to rectal resection and primary anastomosis showed function compromission without differences statistically significant between the laparo and open approach. In the comparison between specific surgical procedures, the damage of continence function were more severe after intersphinteric resection mached with low-ultralow rectal resection. The rehabilitation therapies continued for several months after surgery showed clear improvement. The urinary continence, in male and female patients, did not show statistically significant alterations in the pre and postoperative comparison in relation to the approach and the type of resective intervention. The sexual function in male patients has had impairment after all type of surgical resection but the damage was more severe after intersphinteric resection. The female sexual function had not significant changes between pre and postoperative evaluation., Conclusion: Bowel continence damage, urinary and sexual dysfunctions after surgical treatment for low-ultralow rectal cancer are frequent and form the low anterior resection syndrome. The severity of the syndrome is connected with the site of anastomosis. The rehabilitation therapies can play an important role in achieving the appreciable improvements of the functional alterations., Key Words: Laparoscopic surgery, Rectal cancer.

Background: The management of cholelithiasis and choledocholithiasis combined is controversial. The more frequent approach is a two-stage procedure, with endoscopic sphincterotomy and stone removal from the bile duct followed by laparoscopic cholecystectomy. This study aims to demonstrate how, on the basis of the personal experience, the Rendez-vous technique, that combines the two techniques in a single-stage operation is better than the sequential treatment., Methods: Between June 2017 to December 2019, 40 consecutive patients with cholelithiasis and choledocholithiasis combined were enrolled for the study: 20 were treated with the sequential treatment and 20 with the Rendez-vous method. The preoperative diagnostic work-up was similar in the two group. The endpoints of the study included incidence of endoscopic and surgical complications, rate of hospitalization and cost analysis., Results: The study showed no difference in demographic parameters between the two groups, but the success rate of clearance of CBD was significantly smaller for sequential arm, with the need of additional procedures. We found a statistical reduction of postoperative acute pancreatitis, hospital stay and charges in Rendez-vous group, at the expense of a prolonged total operating time., Conclusions: The data of the study confirm the superiority of the Rendez-vous technique because it resolves cholelithiasis associated with choledocholithiasis in a single surgical act, with greater acceptance of the patient who avoids a second invasive surgical act, and with a reduction in complications; moreover, it requires shorter hospitalization, resulting in reduced costs. We propose this option in the management of cases where preoperative ERCP-ES has failed., Key Words: Common bile duct stones, Cholecysto-choledocholithiasis, Endoscopic retrograde cholangiopancreatography, Endoscopic sphincterotomy, Laparoscopic cholecystectomy, Laparo-endoscopic Rendez-vous.

Introduction: Papillary thyroid carcinoma is the most common type of thyroid cancer worldwide. While total thyroidectomy is widely considered the standard surgical approach for papillary thyroid carcinomas, the role of central lymphadenectomy in early stage poor-risk papillary thyroid tumors is still a matter of debate. This study was designed to assess surgical complications and local disease control rates in patients affected by poor-risk early stage papillary thyroid carcinomas., Methods: We retrospectively analyze three groups of patients affected by poor-risk early stage papillary thyroid carcinomas treated with three alternative surgical strategies: I) routine total thyroidectomy; II) total thyroidectomy and routine central lymphadenectomy; III) total thyroidectomy and central lymphadenectomy upon positive intraoperative histological evaluation of lymph node involvement., Results: Data from patients treated with routine total thyroidectomy showed 32% of persistence of disease in the central compartment with concurrent positivity in laterocervical compartment in 25% of these cases. By contrast, patients receiving total thyroidectomy and routine central lymphadenectomy showed the involvement of central compartment in 40% of cases, while the remaining 60% of patients were free from lymph node metastases. Finally, patients undergoing total thyroidectomy and central lymphadenectomy upon positive intraoperative lymph node biopsy exhibited lack of persistence of lymph node involvement in central compartment after surgery. Of note, postsurgical complications were lower in patients undergoing conservative surgical approaches., Conclusions: These data suggest that central lymphadenectomy, performed only in case of positive intraoperative lymph node biopsy, ensures reduced incidence of postoperative complications and optimal loco-regional disease control., Key Words: Bilateral central neck dissection, Intraoperative lymph node biopsy, Papillary thyroid carcinoma, Poor risk factors.

Background: Minimally invasive surgery for colorectal cancer has been demonstrated to have the same oncological results as open surgery, with better clinical outcomes. Robotic surgery is an evolution of minimally invasive technique. This study aims to evaluate surgical and oncological short-term outcomes of robotic right colon resection in comparison with the laparoscopic approach., Methods: Between January 2014 and May 2017, fifteen laparoscopic right hemicolectomies were compared to seven robotic ones. The primary data points included operation time, length of hospital stay, extraction site incision length, complications, and conversions. When malignancy was the indication for surgery, additional data points have been added., Results: The study showed no difference in parameters between the two groups, but estimated blood loss was significantly smaller for Robotic arm. We found a prolonged total operative room time in the robotic arm, while the surgical time is similar in two groups. The data collected about specimen length and number of lymph nodes suggest that robotic procedure is oncologically similar to laparoscopic one., Conclusions: Robotic approach allows performance of adequate dissection of the right colon with radical lymphadenectomy as in laparoscopic surgery, confirming the safety and oncological efficacy of this technique, with acceptable results and short-term outcomes., Key Words: Da Vinci surgery, XI, Laparoscopic colorectal surgery, Right hemicolectomy, Robot.

Aim: The purpose of this study is to evaluate three different analgesic procedures after laparoscopic cholecystectomy for pain control., Material of Study: The study involved 183 patients who underwent laparoscopic cholecystectomy with the same technique for the induction and maintenance of the general anesthesia. They were divided into three different postoperative pain treatment groups: continuous infusion of Tramadol and Ketorolac with elastomeric pump, intraperitoneal topical instillation of Levobupivacaine, and intraperitoneal aerosolization of Levobupivacaine., Results: No differences were found in the demographics. shorter operating time was observed in group 1. Eight hours after surgery in groups 2 and 3, there was an increase in pain compared to patients in the first group. The request for postoperative analgesic assistance was lower in groups 1 and 2., Discussion: Various topical and intravenous ways for analgesic actions have been used to improve the pain control after laparoscopic procedures, individually and in comparison between them. The main result of our research is that the use of levobupivacaine employed in the topical intraperitoneal application anesthesia by instillation and nebulization, do not improve the postoperative pain in the first 24 hours after LC, compared with intravenous analgesic elastomeric pump., Conclusions: Despite the positive data found in the literature, our observations have not shown a better pain control after laparoscopic cholecystectomy with the use of intraperitoneal analgesia compared to intravenous., Key Words: Gallstone disease, Gallbladder bladder, Laparoscopic cholecystectomy, Postoperative pain, Stones.

Background: In open surgery, the most common approach is Retrograde approach ("fundus first"), while is less frequent in laparoscopic cholecystectomy. Antegrade access, is obtained by putting in traction the infundibulum and reaching up to the fundus right before clipping the cystic. Our study analyzes a number of surgical procedures performed by surgeons with long experience in laparoscopy., Methods: From 2002 to 2017, 2020 laparoscopic cholecystectomies were performed at our Institution. The operative technique used since 2002 is the following: incision of the visceral peritoneum from the infundibulum away from Calot's triangle along the gallbladder bed up to the fundus and then to the infundibulum., Results: No bile duct injuries happened. Average operative time was 38 min. 30 conversions to an open procedure (1.5%) occurred, in patients with cholecystitis and cirrhosis Postoperative stay was mean 2 days with no delayed complications on follow up., Conclusions: Gallbladder antegrade dissection for laparoscopic cholecystectomy may be an easier approach and may reduce the time of surgery. So it may be used as the standard procedure and not only be used for complicated cholecystectomies., Key Words: Difficult cholecystectomy, Laparoscopy, Antegrade dissection, Cholecystectomy, Cholecystitis, Fundus first.

Aim: We present our experience in the laparoscopic management of the hepatic cysts (SHCs) and the polycystic liver disease (PCLD), and a literature review., Material and Methods: Between 2005 and 2018, laparoscopic deroofing was performed in 28 consecutive patients. There were 19 cases with SHCs and only 9 cases with PCLD (Gigot's type I). CT scan was performed in all cases to assess the characteristics, dimensions, and exact position of the lesion. Surgery was planned for all patients because of evident and persistent symptomatology, RESULTS: We have analyzed operative time, surgical procedure, blood loss, hospital stay, complications, and medium follow- up period. All the patients underwent laparoscopic deroofing of the larger cysts and puncturing of the smaller cysts. The total morbidity recorded was 25% (7/28), 3 cases in the group of SHCs (16 %) and 4 cases in the PCLD one (44%) and was characterized of 3 cases of ascites through trocar insertion sites after removal of drainage tube and 4 case of pleural effusion., Discussion: There were no significant group differences in term of length of hospital stay. The follow-up period (a mean of 24 months) confirmed that all the patients remained free of symptoms and relapse of the disease., Conclusion: The technical feasibility and the good short- and medium-term results made the laparoscopic approach the procedure of choice for the management of symptomatic liver cysts., Key Words: Hepatic cyst, Liver disease, Minimally invasive surgery.

Aim: Laparoscopic cholecystectomy for gallstone disease is the most common surgical procedures performed in Western countries and bile leaks remain a significant cause of morbidity. A recognized treatment for minor biliary injury is internal biliary decompression by endoscopic retrograde cholangiopancreatography. The aim of this study was to assess the effectiveness of endoscopic strategy in the management of minor biliary injuries., Material of Study: Twenty-two patients with a bile leak following laparoscopic cholecystectomy were recorded consecutively between 2007 and 2017 and they were all treated with endoscopic approach, with ERCP in order to confirm the nature of the injury and decompress the bile duct with sphincterotomy, stent insertion, or the placement of nasobiliary drains. In 15 patients, the leak was diagnosed by persistent bile drainage, in the other 7 patients without a drain the biliary leak was suspected because of symptoms in the immediate postoperative period., Results: Controlled biliary fistulae were established in all 22 patients (100%), without further intervention. A complete cholangiogram was obtained in all patients (100%). The most common sites of minor leak were the cystic duct stump and the Luschka duct, but in one patients the site of the leak was unclear., Discussion: Early in the series, sphincterotomy alone or nasobiliary tube placement was performed. Subsequently patients underwent sphincterotomy with stent insertion, in order to promote preferential drainage of bile into the duodenum. The median time to resolution after successful ERCP was 4 days. Two patients underwent ERCP complicated by mild pancreatitis. The median hospital stay was 15 days (range, 10-31 days) post-laparoscopic cholecystectomy. ERCP was performed 4-6 weeks later to document healing of the leaking point and to remove the stent. Routine follow was at median 50 days., Conclusions: This review confirms that postoperative minor biliary injuries can be successful managed by endoscopic ERCP biliary decompression., Key Words: Bile leak, Bile duct injury, Biliary fistula, Endoscopy, ERCP, Laparoscopic cholecystectomy.

Introduction: Neuroendocrine tumors (NETs) are a heterogeneous group of tumors. NET of colon represent less than 1% of colonic tumors. Synchronous liver metastases, present in 75-80%, are considered significant adverse prognostic indicators. Liver is the second commonest site for metastasis in patients with colorectal neuroendocrine tumors. Available treatment options include surgical resection, chemotherapy, biotherapy. Surgery is the gold standard for curative therapy and it is strictly related to the localization, the grade of tumor, and the stage of disease., Case Report: We present a 64-year-old man with clinical carcinoid syndrome. Colonoscopy revealed ileocecal valve vegetating mass with negative biopsy. CT scans of thorax and abdomen showed a voluminous lesion (10 cm of diameter) of right liver. CEA, CA 19.9 and aFP were all normal. Only urinary 5HIAASerum 5-hydroxyindoleactic acid and blood Chromogranin A were positive. Surgical strategy was to treat the primary tumor and the liver synchronous metastasis in one stage surgery., Discussion: Management of NETs liver metastases is challenging and requires aggressive therapy. Currently, there are many therapeutic options for metastatic NETs. Although complete surgical resection remains the optimal therapy and aggressive surgical resection increases the 5-year survival of NETs with solitary liver metastasis to 100%. In this case, clinical status with doubt of carcinoid syndrome was essential for diagnosis and for subsequent surgical strategy with one stage surgery., Conclusion: Resection of the primary tumor, liver metastases, and local mesenteric lymph node metastases is thought to strictly promote long-term survival and quality of life. Typically, a multidisciplinary approach is a cornerstone for decision making while dealing with this aggressive disease., Key Words: Carcinoid syndrome, Liver surgery, NETs, Neuroendocrine tumor, One stage surgery, Synchronous liver metastasis.

Aim: The purpose of this study is to communicate our experience about the results and effectiveness in the use of the Ttube biliary drainage during pancreaticoduodenectomy., Material of Study: In accordance whit Whipple we perform the gastric antrum resection during pancreaticoduodenectomy. We have treated 42 patients with pancreaticoduodenectomy, 25 males and 17 females with a mean age of 62 years (range: 53-79 years), and in each of them we have placed a biliary T-tube., Results: Pancreatic fistula was the most common complication and occurred in 10 patients (23.81%), all of these were low-flow fistula (<200 ml) and required only medical treatment., Discussion: Resection of the pancreas is considered a major operative procedure. Pancreatic fistula is the most common complication after pancreaticoduodenectomy, and it was also the most frequent complication observed by us. In pancreaticoduodenectomy T-tube allows lesser risks of complications due to pancreatic fistula and it makes its faster healing. In all cases the treatment was not invasive., Conclusions: T-tube biliary drainage can make a positive contribution concerning all the complications that can occur after pancreaticoduodenectomy, especially against the pancreatic fistula., Key Words: Pancreaticoduodenectomy, Pancreatic fistula, Pancreas head cancer, Pancreatic Tumors, T-tube drainage.

Aim: We report an unusual case of broken adenosarcoma located in the omentum that has procured a clinical situation of acute abdomen in a patient., Case Report: A 79 year-old woman went to the emergency room for growing abdominal pain and then transferred to our department. In previous years the patient had removed endo-cervical and endometrial fibro-glandular polyps and subsequently to a total laparoscopic hysterectomy with bilateral oophorectomy was performed for another endometrial fibroglandular polyp; other vaginal recurrences were then removed. We performed a computed tomography thanks to which we made a diagnosis of moderate hemoperitoneum., Results: The patient underwent to a laparotomy. After abdominal blood removal was evidenced the presence of a damaged big cystic formation starting from the epiploon, containing blood and necrotic debris treated with omentectomy. The subsequent histopathological examination revealed that this tumor was an adenosarcoma., Discussion: Rarely adenosarcoma can grow in extrauterine locations. The simptoms are related to the localization. Even during an emergency surgery it is important to respect the criteria of oncological radicality. You must avoid the tumor dissemination in order to reduce late recurrences, and to achieve a better final histologic diagnosis should avoid intraoperative extemporaneous histological examination., Conclusions: This case is an example of how many diagnostic pitfalls you can hide in emergency surgery, but in conclusion it remains a doubt about our experience: it is not possible to know if this tumor was a primary extra-uterine neoplasm or a recurrence of fibro-glandular polyps removed years before already in malignant transformation?, Key Words: Acute Abdomen, Adenosarcoma, Hemoperitoneum, Omentum.

Aim: The purpose of this study was to determine if there are different outcomes between the right and left laparoscopic adrenalectomy according to our experience., Material of Study: From September 2010 to September 2015 forty-two LA were performed. Variables compared include age, body mass index (BMI), ASA score, operative time, estimated blood loss, conversions, gland size, tumor size, postoperative ambulation, postoperative hospitalization, perioperative and postoperative complications., Results: Substantially there are no difference in postoperative results between right and left LA., Discussion: We report difference in the operative time because left procedure is more complex. The difference in the blood loss due to two intraoperative bleeding in right side, can be considered a given accidental., Conclusions: It's important an adequate learning curve to improve intraoperative and therefore postoperative Outcomes., Key Words: Functioning neoplasms, Laparoscopic adrenalectomy, Laparoscopic transperitoneal adrenalectomy, Minimally invasive surgery, Non-Functioning neoplasm.
