Early diagnosis of anastomotic leakage after colorectal surgery by the Dutch leakage score, serum procalcitonin and serum C-reactive protein: study protocol of a prospective multicentre observational study by the Italian ColoRectal Anastomotic Leakage (iC.

BACKGROUND: Anastomotic leakage (AL) is a dreaded major complication after colorectal surgery. There is no uniform definition of anastomotic dehiscence and leak. Over the years many risk factors have been identified (distance of anastomosis from anal verge, gender, BMI, ASA score) but none of these allows an early diagnosis of AL. The DUtch LeaKage (DULK) score, C reactive protein (CRP) and procalcitonin (PCT) have been identified as early predictors for anastomotic leakage starting from postoperative day (POD) 2-3. The study was designed to prospectively evaluate AL rates after colorectal resections, in order to give a definite answer to the need for clear risk factors, and testing the diagnostic yeld of DULK score and of laboratory markers. Methods and analysis. A prospective enrollment for all patients undergoing elective colorectal surgery with anastomosis carried out from September 2017 to September 2018 in 19 Italian surgical centers. OUTCOME MEASURES: preoperative risk factors of anastomotic leakage; operative parameters; leukocyte count, serum CRP, serum PCT and DULK score assessment on POD 2 and 3. Primary endpoint is AL; secondary endpoints are minor and major complications according to Clavien-Dindo classification; morbidity and mortality rates; readmission and reoperation rates, length of postoperative hospital stay (Retrospectively registered at ClinicalTrials.gov Identifier: NCT03560180, on June 18, 2018). Ethics. The ethics committee of the "Comitato Etico Regionale delle Marche - C.E.R.M." reviewed and approved this study protocol on September 7, 2017 (protocol no. 2017-0244-AS). All the participating centers submitted the protocol and obtained authorization from the local Institutional Review Board.

Technical solutions for venous outflow reconstruction in damaged liver grafts during procurement: case reports.

The incidence and clinical consequences of hepatic injuries (parenchymal, vascular, and biliary) due to surgical handling during multiorgan procurement are still underestimated. Surgical damage to liver grafts may lead to an increased mortality and graft dysfunction rate; therefore, multiorgan procurements require a high level of expertise and training. We report our experience in two cases of accidental venous outflow damage during liver procurement focusing on our repair strategies. In one case, a short suprahepatic inferior vena cava (IVC) was extended by a venous cuff obtained from a long infrahepatic IVC from the same liver graft. In the second case, we observed a complete transection of the middle hepatic vein during in situ splitting procedure. The damage was reconstructed by cadaveric iliac vein interposition. In both cases, liver transplantation was successfully performed without venous complication. An adequate surgical technique in liver procurement and venous reconstruction during living donor and domino liver transplantation are formidable tools to achieve successful liver transplantation with a damaged graft.

Peritoneal leiomyosarcoma in a kidney transplant patient: a case report.

Sarcomas are rare neoplasms, accounting for a 1.7% incidence among all transplanted patients presenting with de novo malignancies. Our present report focused on a 46-year-old woman who received immunosuppressive therapy based on cyclosporine and steroids for renal transplantation. Eight years after transplantations, she suffered lower abdominal pain and a mass involving peritoneal soft tissues was located near the right iliac vessels. Upon radical tumor excision, the histological examination revealed a high-grade leiomyosarcoma. Immunosuppression was reduced and cyclosporine switched to rapamycin. After 30 days, a computed tomography scan revealed two small pulmonary metastases, so the patient received adriamycin. Six months after the diagnosis, there was no intra-abdominal relapse and the pulmonary metastasis remain stable. The function of the transplanted kidney was normal and the patient was listed for laparoscopic pulmonary resection. Sarcomas in solid organ transplant patients appear to have aggressive features with 62% being high grade and 40% metastatic at the time of primary diagnosis with a recurrence rate of 30% and a 5-year survival rate of 25%. Patients diagnosed with sarcoma should be treated with multimodality therapy. After aggressive surgery whenever possible, a combination of a traditional cytotoxic drug and a "signal" blocking agent like rapamycin may increase selectivity toward tumor cells.
