RESUMO
BACKGROUND: The rising diffusion of vascular resections during complex pancreatectomy for malignancy, for both oncological and technical matters, brought with it the use of vascular shunts, either temporary or definitive, to prevent bowel congestion and liver ischemia. This study aimed to systematically review the literature on the technical feasibility of vascular shunts during advanced pancreatic surgery, analyzing intraoperative and postoperative outcomes. METHODS: A systematic literature search was performed on PubMed, Scopus, Web of Science, and the Cochrane Library Central, according to PRISMA guidelines. Studies published before 2006 were excluded, considering the lack of a standardized definition of locally advanced pancreatic cancer. The main outcomes evaluated were the overall complication rate and shunt patency. RESULTS: Among 789 papers retrieved from the database search, only five fulfilled the inclusion criteria and were included in the review, amounting to a total of 145 patients undergoing a shunt creation at the time of pancreatectomy. Pancreatic adenocarcinoma (PDAC) was found to be the most common diagnosis and pancreaticoduodenectomy was the main surgical procedure, accounting for 88% and 83% of the overall cohort, respectively. The distal splenorenal shunt was the most performed. Overall, 44 out of 145 patients (30%) experienced postoperative complications; the long-term patency of definitive shunts was 83% (110 out of 120 patients). CONCLUSIONS: An increasing number of patients with borderline resectable or locally advanced PDAC are becoming amenable to resection and shunt creation may facilitate vascular resection with clear margins, becoming a valid tool of modern pancreatic surgery.
RESUMO
BACKGROUND: the role of minimally invasive liver surgery has been progressively developed, with the practice increasing in safety and feasibility also with respect to major liver resections. The aim of this study was to analyze the feasibility and safety of major liver resection in elderly patients. METHODS: data from a multicentric retrospective database including 1070 consecutive robotic liver resections in nine European hospital centers were analyzed. Among these, 131 were major liver resections. Patients were also divided in two groups (<65 years old and ≥65 years old) and perioperative data were compared between the two groups. RESULTS: a total of 131 patients were included in the study. Operative time was 332 ± 125 min. Postoperative overall complications occurred in 27.1% of patients. Severe complications (Clavien Dindo ≥ 3) were 9.9%. Hospital stay was 6.6 ± 5.3 days. Patients were divided into two groups based on their age: 75 patients < 65 years old and 56 patients ≥ 65 years old. Prolonged pain, lung infection, intensive care stay, and 90-day readmission were worse in the elderly group. The two groups were matched for ASA and Charlson comorbidity score and, after statistical adjustment, postoperative data were similar between two groups. CONCLUSIONS: robotic major liver resection in elderly patients was associated with satisfying short-term outcomes.
RESUMO
BACKGROUND: In this article we aimed to perform a subgroup analysis using data from the COVID-AGICT study, to investigate the perioperative outcomes of patients undergoing surgery for pancreatic cancers (PC) during the COVID-19 pandemic. METHODS: The primary endpoint of the study was to find out any difference in the tumoral stage of surgically treated PC patients between 2019 and 2020. Surgical and oncological outcomes of the entire cohort of patients were also appraised dividing the entire peri-pandemic period into six three-month timeframes to balance out the comparison between 2019 and 2020. RESULTS: Overall, a total of 1815 patients were surgically treated during 2019 and 2020 in 14 Italian surgical Units. In 2020, the rate of patients treated with an advanced pathological stage was not different compared to 2019 (p = 0.846). During the pandemic, neoadjuvant chemotherapy (NCT) has dropped significantly (6.2% vs 21.4%, p < 0.001) and, for patients who didn't undergo NCT, the latency between diagnosis and surgery was shortened (49.58 ± 37 days vs 77.40 ± 83 days, p < 0.001). During 2020 there was a significant increase in minimally invasive procedures (p < 0.001). The rate of postoperative complication was the same in the two years but during 2020 there was an increase of the medical ones (19% vs 16.1%, p = 0.001). CONCLUSIONS: The post-pandemic dramatic modifications in healthcare provision, in Italy, did not significantly impair the clinical history of PC patients receiving surgical resection. The present study is one of the largest reports available on the argument and may provide the basis for long-term analyses.

Screening methods available for colorectal cancer (CRC) to date are burdened by poor reliability and low patient adherence and compliance. An altered pattern of volatile organic compounds (VOCs) in exhaled breath has been proposed as a non-invasive potential diagnostic tool for distinguishing CRC patients from healthy controls (HC). The aim of this study was to evaluate the reliability of an innovative portable device containing a micro-gas chromatograph in enabling rapid, on-site CRC diagnosis through analysis of patients' exhaled breath. In this prospective trial, breath samples were collected in a tertiary referral center of colorectal surgery, and analysis of the chromatograms was performed by the Biomedical Engineering Department. The breath of patients with CRC and HC was collected into Tedlar bags through a Nafion filter and mouthpiece with a one-way valve. The breath samples were analyzed by an automated portable gas chromatography device. Relevant volatile biomarkers and discriminant chromatographic peaks were identified through machine learning, linear discriminant analysis and principal component analysis. A total of 68 subjects, 36 patients affected by histologically proven CRC with no evidence of metastases and 32 HC with negative colonoscopies, were enrolled. After testing a training set (18 CRC and 18 HC) and a testing set (18 CRC and 14 HC), an overall specificity of 87.5%, sensitivity of 94.4% and accuracy of 91.2% in identifying CRC patients was found based on three VOCs. Breath biopsy may represent a promising non-invasive method of discriminating CRC patients from HC.

INTRODUCTION: Lemmel's syndrome is a rare disease presenting with obstructive jaundice, secondary to common bile duct compression by duodenal diverticulum. PRESENTATION OF CASE: A 79-year-old female was admitted to our emergency department with cholangitis and obstructive jaundice, due to choledocal compression by two periampullary diverticula, with major papilla opening near the biggest one (periampullary diverticulum type III). Endoscopic retrograde cholangiopancreatography didn't succeed sphincterotomy, therefore laparoscopic rendez-vous was performed. DISCUSSION: This case is an example of an unusual cause of obstructive jaundice, which should be mentioned along with choledocolithiasis and biliary or ampullary neoplasms, in order to avoid delay in diagnosis and management. CONCLUSION: The commonest treatment of Lemmel's syndrome reported in literature is ERCP with sphincterotomy, but when endoscopic management fails, interventional radiology and surgery should also be considered.
RESUMO
INTRODUCTION AND IMPORTANCE: Amyand's hernia is a rare type of inguinal hernia which contains vermiform appendix in the inguinal sac, seldom complicated by acute appendicitis. It is usually repaired by open inguinal approach, but laparoscopic technique has been increasingly described in literature; nevertheless, standard of care is far from being defined. Here we report the case of Amyand's hernia complicated by acute appendicitis and simultaneous symptomatic left inguinal hernia, both repaired by laparoscopic technique. CASE PRESENTATION: A 85-years-old man presented with acute appendicitis in Amyand's hernia and simultaneous incarcerated left inguinal hernia. CLINICAL DISCUSSION: After complete preoperative work-up, the patient underwent laparoscopic appendectomy and laparoscopic bilateral hernia repair with mesh. CONCLUSION: Laparoscopic approach may be safe and feasible for Amyand's hernia treatment in emergency setting when performed by expert hands, with minimized risk of surgical site infection (SSI), quick recovery and reduced hospital stay. Laparoscopic hernia repair with mesh can be a reasonable approach in selected cases of bilateral or recurrent hernia, and concomitant intrabdominal inflammation, especially when contamination is scarse and limited to a restricted area.
RESUMO
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.
