RESUMO

This study depicts the case of a young female presenting with intestinal obstruction. Surgery uncovered a small bowel hamartoma that has caused a transmesenteric internal hernia and volvulus. As far as we know, this is unheard of before, as all three mentioned entities are very rare. The study also covers a literature review of cases of internal hernia with volvulus and stresses over the need for urgent diagnosis and management.

RESUMO

Short telomere length (TL) is associated with atherosclerotic cardiovascular disease (ACVD) and other age-related diseases. It is unclear whether these associations originate from having inherently short TL or a faster TL attrition before or during disease development. We proposed the blood-and-muscle model to assess TL dynamics throughout life course. Our objective was to measure TL in leukocytes (LTL) and in skeletal muscle (MTL), which served as a proxy of TL at birth. The delta (MTL-LTL) represented life-long telomere attrition. Blood draws and skeletal muscle biopsies were performed on 35 Lebanese individuals undergoing surgery. Following DNA extraction, LTL and MTL were measured by Southern blot. In every individual aged between 30 and 85 years, MTL was longer than LTL. With age, MTL and LTL decreased, but the delta (MTL-LTL) increased by 14 bp/year. We validated the blood-and-muscle model that allowed us to identify TL, TL at birth, and lifelong TL attrition in a cross-sectional study. This model can be used in larger cross-sectional studies to evaluate the association of telomere dynamics with age-related diseases onset and progression.

RESUMO

BACKGROUND: Postoperative complications (POCs) after the resection of locally advanced colorectal cancer (CRC) may influence adjuvant treatment timing, outcomes, and survival. This study aimed to evaluate the impact of POCs on long-term outcomes in patients surgically treated for T4 CRC. METHODS: All consecutive patients who underwent the resection of T4 CRC at a single centre from 2004 to 2013 were retrospectively analysed from a prospectively maintained database. POCs were assessed using the Clavien-Dindo classification. Patients who developed POCs were compared with those who did not in terms of recurrence-free survival (RFS) and overall survival (OS). RESULTS: The study population comprised 106 patients, including 79 (74.5%) with synchronous distant metastases. Overall, 46 patients (43%) developed at least one POC during the hospital stay, and of those patients, 9 (20%) had severe complications (Clavien-Dindo ≥ grade III). POCs were not associated with OS (65% with POCs vs. 69% without POCs; p = 0.72) or RFS (58% with POCs vs. 70% without POCs; p = 0.37). Similarly, POCs did not affect OS or RFS in patients who had synchronous metastases at diagnosis compared with those who did not. CONCLUSIONS: POCs do not affect the oncological course of patients subjected to the resection of T4 CRC, even in cases of synchronous metastases.

RESUMO

BACKGROUND: Elective liver resection (LR) in Jehovah's Witness (JW) patients, for whom transfusion is not an option, involves complex ethical and medical issues and surgical difficulties. METHODS: Consecutive data from a LR program for liver tumors in JWs performed between 2014 and 2017 were retrospectively reviewed. A systematic review of the literature with a pooled analysis was performed. RESULTS: Ten patients were included (median age = 61 years). None needed preoperative erythropoietin. Tumor biopsy was not performed. Major hepatectomy was performed in 4 patients. The median estimated blood loss was 200 mL. A cell-saver was installed in 2 patients, none received saved blood. The median hemoglobin values before and at the end of surgery were 13.4 g/dL and 12.6 g/dL, respectively (p = 0.04). Nine complications occurred in 4 patients, but no postoperative hemorrhage occurred. In-hospital mortality was nil. Nine studies including 35 patients were identified in the literature; there was reported no mortality and low morbidity. None of the patients were transfused. CONCLUSIONS: By using a variety of blood conservation techniques, the risk/benefit ratio of elective liver resection for liver was maintained in selected adult JW patients. JW faith should not constitute an absolute exclusion from hepatectomy.

RESUMO

The management of large spontaneous portosystemic shunt (SPSS) during liver transplantation (LT) is a matter of debate. The aim of this study is to compare the short-term and longterm outcomes of SPSS ligation versus nonligation during LT, when both options are available. From 2011 to 2017, 66 patients with SPSS underwent LT: 56 without and 10 with portal vein thrombosis (PVT), all of whom underwent successful thrombectomy and could have portoportal reconstruction. The SPSS were either splenorenal (n = 40; 60.6%), left gastric (n = 16; 24.2%), or mesenterico-iliac (n = 10; 15.1%). Following portoportal anastomosis, the SPSS was ligated in 36 (54.4%) patients and left in place in 30 (45.5%) patients, based on the effect of the SPSS clamping/unclamping test on portal vein flow during the anhepatic phase. Intraoperatively, satisfactory portal flow was obtained in both groups. Primary nonfunction (PNF) and primary dysfunction (PDF) rates did not differ significantly between the 2 groups. Nonligation of SPSS was significantly associated with a higher rate of postoperative encephalopathy (P < 0.001) and major postoperative morbidity (P = 0.02). PVT occurred in 0 and 3 patients in the ligated and nonligated shunt group, respectively (P = 0.08). A composite end point, which included the relevant complications in the setting of SPSS in LT (ie, PNF and PDF, PVT, and encephalopathy) was present in 16 (44.4%) and 22 (73.3%) patients of the ligated and nonligated shunt group, respectively (P = 0.02). Patient (P = 0.05) and graft (P = 0.02) survival rates were better in the ligated shunt group. In conclusion, the present study supports routine ligation of large SPSS during LT whenever feasible.

RESUMO

BACKGROUND: Portal hypertension (PHTN) increases the risk of non-hepatic surgery in cirrhotic patients. This first systematic review analyzes the place of transjugular intrahepatic portosystemic shunt (TIPS) in preparation for non-hepatic surgery in such patients. METHODS: Medline, EMBASE, and Scopus databases were searched from 1990 to 2017 to identify reports on outcomes of non-hepatic surgery in cirrhotic patients with PHTN prepared by TIPS. Feasibility of TIPS and the planned surgery, and the short- and long-term outcomes of the latter were assessed. RESULTS: Nineteen studies (64 patients) were selected. TIPS was indicated for past history of variceal bleeding and/or ascites in 22 (34%) and 33 (52%) patients, respectively. The planned surgery was gastrointestinal tract cancer in 38 (59%) patients, benign digestive or pelvic surgery in 21 (33%) patients and others in 4 (6%) patients. The TIPS procedure was successful in all, with a nil mortality rate. All patients could be operated within a median delay of 30 days from TIPS (mortality rate = 8%; overall morbidity rate = 59.4%). One year overall survival was 80%. CONCLUSIONS: TIPS allows non-hepatic surgery in cirrhotic patients deemed non operable due to PHTN. Further evidence in larger cohort of patients is essential for wider applicability.

RESUMO

In patients with malignancy who receive aflibercept based chemotherapy, gastrointestinal perforation is among the reported adverse events with a prevalence of 1.9%. This complication may lead to mortality up to 10.8%. We here report a case of small bowel perforation that occurred fifteen days after the first cycle of aflibercept in a 58-year old female who had metachronous colorectal liver metastases. Emergency laparotomy was performed and revealed a small bowel perforation without any anastomotic dehiscence. Surgery was followed by uneventful outcome. The use of aflibercept in patients with malignancy may be associated with very early gastrointestinal perforation and this should be known by oncologist and surgeons.
