RESUMO
BACKGROUND AND AIMS: Gallbladder carcinoma is a rare but aggressive malignant neoplasm. The incidence of intra- or post-operative incidental gallbladder carcinoma diagnosis following laparoscopic cholecystectomy is estimated to be 1-2%. Aggressive re-resection is warranted as the majority of patients have residual disease either in the liver or the lymph nodes. However the use of a minimally invasive surgical approach (MISA) to perform a radicalization in these patients has not been investigated yet. We retrospectively analyzed surgical and oncologic outcome of a small selected cohort of patients with incidental gallbladder carcinoma whom underwent redo radicalization surgery by MISA. MATERIAL AND METHODS: From April 2012 to June 2014 at our department six patients (three females and three males) with incidental findings of gallbladder carcinoma pT1b (stage I) following laparoscopic cholecystectomy, and referred to our center from other secondary-level referral hospitals, underwent a redo surgery for radicalization by means of laparoscopic (n. 3) or robotic approach (n. 3). A retrospective analysis of prospective collected data was performed. RESULTS: The redo procedure consisted of a liver resection (segments IVb + V) and lymph nodes clearance of hepatoduodenal hilum and common hepatic artery. Conversion rate was zero. Median operative time was 290 (250-310) min. Estimate blood loss was 175 (100-350) ml. Total hospital stay was 6 (5-10) days. All liver resections were performed without inflow vascular clamping. One patient was re-operated for hemoperitoneum while peri-operative mortality was zero. Oncologically, an R0 resection was always achieved with a mean number of lymph nodes retrieved of 17,5 (14-22). The stage of the neoplasm was confirmed in all cases but one, who was found to have a pN1 status (stage IIIb). At 21 (6-32) months follow-up all patients are alive and no recurrence has been observed. CONCLUSIONS: Our data suggest that radicalization of patients with stage I incidental postoperative gallbladder carcinoma can be done by a MISA without compromising the oncologic outcome. Larger studies are needed to validate these results.

Introduction: During the last year, the features of peritoneal dialysis patients have changed, and the cases in which there is a need to perform abdominal surgery are growing. Reports of abdominal surgery in patients who are able to continue peritoneal dialysis are increasing. The minimally invasive techniques represent the preferred and safest approach. Such techniques are associated with reduced hospitalization time, less invasiveness, peritoneal integrity preservation, and reduced intra-abdominal inflammation due to regenerative processes. Case Presentation: In this case report, we present a case of major abdominal surgery, in the form of hepatic metastasectomy, performed with the robotic-assisted technique, which allowed catheter and intracorporeal dialysis preservation. The patient showed a strong determination to continue with peritoneal dialysis as long as possible. During the switch to hemodialysis, he performed prophylactic antibiotic therapy to preserve the peritoneal catheter, and the patient was instructed to have a reduced water intake, avoiding excessive ultrafiltration potentially deteriorating the residual renal function. Special care was also taken to avoid any nephrotoxic drug. The peritoneal treatment was restarted after 3 weeks with low volume exchange for the first 10 days, and the pre-surgery dialysis volumes were then re-established. After surgery, the patient showed adequate clearance of solutes and ultrafiltration similar to the preoperative period. The patient did not encounter any wound complications. Conclusion: Robotic surgery represents a further aid in peritoneal dialysis preservation after abdominal surgery. A detailed communication with the patient before performing this kind of procedure and a strong will to preserve the peritoneal method are essential.
RESUMO
Acinar cystic transformation (ACT), also known as 'acinar cell cystadenoma', is an uncommon cystic neoplasm of pancreas with unknown malignant potential. This case regards a woman with symptomatic pancreatic head ACT, revealed with pathological exam of specimen after pancreaticoduodenectomy. A 57-years-old patient presented mild hyperbilirubinemia and recurrent cholangitis; she underwent to ERCP, EUS and MRI, and these exams revealed a large cyst of the pancreatic head that caused biliary compression. The discussion of the case by the multidisciplinary group indicated surgical resection. Pancreatic ACT is so rare, and its preoperative diagnosis is difficult. The symptoms of the patients and the features of the cyst are the criteria to choose a surgical resection.
RESUMO
BACKGROUND: To date, no standardized protocols nor a quantitative assessment of the near-infrared fluorescence angiography with indocyanine green (NIR-ICG) are available. The aim of this study was to evaluate the timing of fluorescence as a reproducible parameter and its efficacy in predicting anastomotic leakage (AL) in colorectal surgery. METHODS: A consecutive cohort of 108 patients undergoing minimally invasive elective procedures for colorectal cancer was prospectively enrolled. The difference between macro and microperfusion (ΔT) was obtained by calculating the timing of fluorescence at the level of iliac artery division and colonic wall, respectively. RESULTS: Subjects with a ΔT ≥ 15.5± 0.5 s had a higher tendency to develop an AL (p < 0.01). The ΔT/heart rate interaction was found to predict AL with an odds ratio of 1.02 (p < 0.01); a cut-off threshold of 832 was identified (sensitivity 0.86, specificity 0.77). Perfusion parameters were also associated with a faster bowel motility resumption and a reduced length of hospital stay. CONCLUSIONS: The analysis of the timing of fluorescence provides a quantitative, easy evaluation of tissue perfusion. A ΔT/HR interaction ≥832 may be used as a real-time parameter to guide surgical decision making in colorectal surgery.
RESUMO
Solid pseudopapillary tumour is a rare low-grade malignant potential carcinoma of the pancreas that typically occurs in females in their third decade. It most commonly occurs in the tail of the pancreas, although any site can be affected. Surgical resection is the standard treatment and offers an excellent prognosis. We report a case of a 17-year-old female with an acute onset abdominal pain and a radiological diagnosis of a cystic lesion in the distal pancreas. A robotic-assisted distal pancreatectomy with splenectomy was performed. Robotic-assisted surgery is an emerging technique for the treatment of pancreatic neoplasms. This approach can be considered for younger patients, thanks to the potential advantages of the robotic Da Vinci Xi System.
RESUMO
BACKGROUND: The increasing age of the population and prolonged life expectancy result in a widening of age limit criteria for a variety of surgical procedures. Oesophagectomy and total gastrectomy are complex operations associated with significant risks of post-operative complications. METHODS: This is a single-centre cohort study of patients operated with curative intent due to oesophageal or gastric cancer. RESULTS: From 2007 to 2017, 548 patients underwent surgery with curative intent, with 122 patients (22.3%) classified as elderly (≥75 years). There was no difference in total complication rates between the groups. The adjusted odds ratio for 90-day mortality after oesophageal resection in the elderly group was 3.65 (95% confidence interval (CI): 1.33-10.03) and after gastrectomy was 1.62 (95% CI: 0.55-4.79). The adjusted hazard ratio for 1-year mortality after oesophagectomy was 2.29 (95% CI: 1.25-4.19), and after gastrectomy the adjusted hazard ratio was 1.48 (95% CI: 0.75-2.92). In the event of a complication with Clavien-Dindo score IIIb or higher, there was a statistically significant increase of 90-day mortality to over 50% among elderly patients both after oesophagectomy and gastrectomy (50.0% versus 19.8%; P = 0.005 and 57.1% versus 17.4%; P = 0.012, respectively). CONCLUSION: There is a statistically significant increase in 90-day mortality after oesophageal and gastric cancer surgery in elderly compared with younger patients. Post-operative complications with high Clavien-Dindo score in patients undergoing oesophagectomy or gastrectomy, with age ≥75 years, are a dramatic risk factor for post-operative death.

BACKGROUND: The indications of esophageal replacement (ER) in pediatric patients include long gap esophageal atresia (LGEA), intractable post-corrosive esophageal strictures (PCES), and some rare esophageal diseases. Various conduits and procedures are currently used worldwide with a lack of consensus regarding the ideal substitute to replace the esophagus replacement. The short-term outcomes of these advanced procedures are well known; there are few data available describing long-term functional outcomes of these patients with long life expectancy. OBJECTIVES: The objective of this study is to investigate the long-term functional outcomes of the most widely used techniques for ER in pediatric patients based on a comprehensive literature search covering the last 10years. METHODS: Eligible were all clinical studies reporting outcomes after esophagectomy in pediatric patients, which contained information on at least 3years of follow-up after the operation. The review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A systematic web-based search using MEDLINE, the Cochrane Library and EMBASE databases was performed, reviewing all medical literature published between January 2006 and December 2015. RESULTS: The scientific quality of the data was generally poor, converging toward only 14 full-text articles for the final analysis. The stomach was the preferred organ for esophageal replacement, where the tubulization of the stomach resulted in significant gastroesophageal reflux. Dysphagia symptoms were more seldom reported, but several authors presented growing figures with the length of follow-up. Dumping syndrome and delayed gastric emptying were only scarcely reported upon. Following colonic graft, chronic gastrocolic reflux affects these patients, in the range of 35-70.8%, while 4 studies reported any dysphagia from 2.7% to 50% of the children. Only one study reported the outcome of the use of a long jejunal segment, where presence of symptoms of functional obstruction was mentioned in 46% of cases. Very few if any data were available on a structured assessment of postprandial dumping and disturbed bowel functions. CONCLUSIONS: Available data in pediatric patients, on the long-term functional outcomes after esophageal replacement with a gastric tube, colonic graft or a long jejunal segment, are of poor scientific quality. Although symptoms are frequently reported currently no conclusions can be drawn regarding potential advantages of one graft over another. TYPE OF STUDY: Treatment study, systematic review. LEVEL OF EVIDENCE: IV.

Purpose. To analyse perioperative and oncological outcomes of minimally invasive simultaneous resection of primary colorectal neoplasm with synchronous liver metastases. Methods. A Medline revision of the current published literature on laparoscopic and robotic-assisted combined colectomy with hepatectomy for synchronous liver metastatic colorectal neoplasm was performed until February 2015. The specific search terms were "liver metastases", "hepatic metastases", "colorectal", "colon", "rectal", "minimally invasive", "laparoscopy", "robotic-assisted", "robotic colorectal and liver resection", "synchronous", and "simultaneous". Results. 20 clinical reports including 150 patients who underwent minimally invasive one-stage procedure were retrospectively analysed. No randomized trials were found. The approach was laparoscopic in 139 patients (92.7%) and robotic in 11 cases (7.3%). The rectum was the most resected site of primary neoplasm (52.7%) and combined liver procedure was in 89% of cases a minor liver resection. One patient (0.7%) required conversion to open surgery. The overall morbidity and mortality rate were 18% and 1.3%, respectively. The most common complication was colorectal anastomotic leakage. Data concerning oncologic outcomes were too heterogeneous in order to gather definitive results. Conclusion. Although no prospective randomized trials are available, one-stage minimally invasive approach seems to show advantages over conventional surgery in terms of postoperative short-term course. On the contrary, more studies are required to define the oncologic values of the minimally invasive combined treatment.

AIM: evaluate emergency treatment of patients presenting with anaplastic thyroid cancer with acute compressive sympthoms. MATERIAL OF STUDY: In the present report, we describe three patients with anaplastic thyroid cancer who presented clinically with acute compressive sympthoms. All patients underwent debulking surgery in order to relieve the sympthoms and perform a potentially curative resection. RESULTS: The first two patients with diagnosis of ATC couldn't undergo to radiotherapy and chemotherapy for the presence of infection of the wound and for the earlier disease relapse in the mediastinum and died after 1 month and 3 months. The third patient (with papillary thyroid cancer with focal areas of anaplastic cancer) after surgical treatment underwent external radiotherapy and is alive over 2 years. DISCUSSION: Compression, deviation, and infiltration of trachea have impeded the achievement of a safe respiratory access with tracheostomy and these three patients underwent debulking surgery to relieve compressive sympthoms. These three cases confirm the importance of acute local compressive symptoms of ATC and their difficult management. CONCLUSIONS: In such cases a debulking surgery can be considered as a valid option in the emergency management. Nevertheless debulking surgery (and even radical excision of the tumor), when performed alone, offer a minimal improved survival.
