Long-Term Results of Endoscopic Metal Stenting for Biliary Anastomotic Stricture after Liver Transplantation.

(1) Background: Anastomotic biliary stricture (ABS) is a well-known complication of liver transplantation which can lead to secondary biliary cirrhosis and graft dysfunction. The goal of this study was to evaluate the long-term outcomes of endoscopic metal stenting of ABS in the setting of deceased donor liver transplantation (DDLT). (2) Methods: Consecutive DDLT patients with endoscopic metal stenting for ABS between 2010 and 2015 were screened. Data on diagnosis, treatment and follow-up (until June 2022) were collected. The primary outcome was endoscopic treatment failure defined as the need for surgical refection. (3) Results: Among the 465 patients who underwent LT, 41 developed ABS. It was diagnosed after a mean period of 7.4 months (+/-10.6) following LT. Endoscopic treatment was technically successful in 95.1% of cases. The mean duration of endoscopic treatment was 12.8 months (+/-9.1) and 53.7% of patients completed a 1-year treatment. After a mean follow-up of 6.9 years (+/-2.3), endoscopic treatment failed in nine patients (22%) who required surgical refection. Conclusions: Endoscopic management with metal stenting of ABS after DDLT was technically successful in most cases, and half of the patients had at least one year of indwelling stent. Endoscopic treatment long-term failure rate occurred in one fifth of the patients.

Patients' comorbidities reduce the clinical value of emergency colonoscopy: results of a retrospective cohort study.

BACKGROUND AND STUDY AIMS: Urgent endoscopy is often used to diagnose and sometimes treat acute upper gastrointestinal syndromes (hemorrhage, toxic ingestion, and occlusion). However, its suitability concerning the management of lower gastrointestinal conditions in emergency circumstances is controversial. PATIENTS AND METHODS: We studied the role of emergency colonoscopy in diagnosis and treatment of all consecutive patients presenting with acute lower gastrointestinal symptoms referred to our hospital on an emergency basis. All patients were first managed by physicians from the emergency room and/or the intensive care unit (ICU); the treatments included fluid resuscitation, blood transfusion, and antibiotic or cardiotonic as needed. Bowel cleansing was performed to purge the colon of clots, stool, and blood when clinically possible; alternatively, a bowel enema was used. Patients only underwent a computed tomography (CT) scan prior to the colonoscopy in clinically relevant situations. Colonoscopy was performed within 6 - 36 hours after hospitalization or the beginning of the clinical symptoms (hemorrhage, sepsis, colon distension) or occlusion, as assessed by abdominal CT scan. RESULTS: From 2010 to 2015, 603 patients underwent urgent colonoscopy; among them, 214 (36 %) presented with lower GI bleeding, while 264 (44 %) had symptoms suggestive of intestinal ischemia; almost half (49 %, n = 295) of the patients were hospitalized in the ICU. Patients received therapies, such as clips (15 %), epinephrine injections (5 %), bipolar coagulation (7 %), or devolvulation (3 %) using colonoscopy or antibiotic therapy when needed. No perforation was observed after colonoscopy and only three cases of hemorrhage recurrence were documented as complications after the procedure. Overall, 192 patients died within 1 month after colonoscopy due to four independent risk situations, as follows: septic shock, heart transplantation, multiorgan failure, and ischemic colitis. Only 67 (35 %) underwent urgent intestinal surgery when ischemic colitis was identified, and this did not have a significant effect on the mortality rate. CONCLUSIONS: Urgent bedside colonoscopy is feasible and safe for routine use. The highest advantage was observed in patients with red blood hemorrhage, diarrhea, and colon distension when symptoms were not associated with multiorgane failure, heart transplantation, or septic shock. As revealed by colonoscopy and pathological features, ischemic colitis is associated with a bad prognosis, and patients experience a higher rate of early mortality regardless of whether they undergo urgent colon surgery.

Total colectomy for cancer: analysis of factors linked to patients' age.

Total colectomy (TC) is a valid option for cancer treatment in selected cases. Emergency presentation, association to familial adenomatous polyposis (FAP) or intestinal bowel disease (IBD), hereditary non-polyposis cancer (HNPCC), and synchronous tumors are the common indications to TC for cancer. Despite potential high morbidity and mortality rates for worse general health conditions of the advanced age it has even suggested for elderly patients. We reviewed our experience to analyze the current role of TC comparing different results between young and elderly patients. During the period 1990-2012, 76 patients were operated on TC for cancer. Patients were divided in two groups according to the age [<65 - group A (young) and >65 years old - group B (elderly)] and were compared their systemic and surgical complication, considering the presence of comorbidities, ASA score, lifestyle habits, elective or emergency presentation. Morbidity rate was 7.7% and 38.8% in young and elderly patients respectively. 21 systemic complications (3 in group A and 18 in group B) occurred in 17 patients (22.36%) (with the coexistence of two complications in 4 patients belonging to the group B. There were 6 surgical complications (7.9%) (3 in group A and 3 in group B): anastomotic leakage 3, major wound infections 2, postoperative bleeding 1; no intra-abdominal abscess were observed. In 2 cases (2.6%) (1 anastomotic leak and 1 intra-abdominal postoperative hemorrhage) was needed a reoperation. We observed only 2 deaths in the elderly. High ASA score and emergency were associated with worst results. Systemic complications were more frequent in elderly patients cause of significant comorbidities, while the incidence of surgical complications was similar and according to literature. Besides the classic indications, it is a viable surgical option also in cancer associated with complicated diverticulitis. Our data show that TC is a safe and effective procedure providing good results even in elderly patients, when combined with a careful preoperative evaluation and age is not an absolute controindication to this procedure.
