Risk factors for major complications after surgical treatment of primary ileocecal Crohn's disease. A multicentric Latin American experience

INTRODUCTION

Complications after ileocecal resection for Crohn's disease (CD) are frequent. The aim of this study was to analyze risk factors for postoperative complications after these procedures.

MATERIALS AND METHODS

We conducted a retrospective analysis of patients treated surgically for Crohn's disease limited to the ileocecal region during an 8-year period at 10 medical centers specialized in inflammatory bowel disease (IBD) in Latin America. Patients were allocated into 2 groups: those who presented major postoperative complications (Clavien-Dindo > II), the "postoperative complication" (POC) group; and those who did not, the "no postoperative complication" (NPOC) group. Preoperative characteristics and intraoperative variables were analyzed to identify possible factors for POC.

RESULTS

In total, 337 patients were included, with 51 (15.13%) in the POC cohort. Smoking was more prevalent among the POC patients (31.37 vs. 17.83; P = .026), who presented more preoperative anemia (33.33 vs. 17.48%; P = .009), required more urgent care (37.25 vs. 22.38; P = .023), and had lower albumin levels. Complicated disease was associated with higher postoperative morbidity. POC patients had a longer operative time (188.77 vs. 143.86 min; P = .005), more intraoperative complications (17.65 vs. 4.55%; P < .001), and lower rates of primary anastomosis. In the multivariate analysis, both smoking and intraoperative complications were independently associated with the occurrence of major postoperative complications.

CONCLUSION

This study shows that risk factors for complications after primary ileocecal resections for Crohn's disease in Latin America are similar to those reported elsewhere. Future efforts in the region should be aimed at improving these outcomes by controlling some of the identified factors.

Antioxidant diet and genotyping as tools for the prevention of liver disease

It is well-known that 75% of risk factors of chronic liver disease (CLD) are related to nutrition. These circumstances potentially progress towards liver steatosis, fibrosis and hepatocellular carcinoma (HCC). It still represents an enormous problem for the economy of public health worldwide. Furthermore, validated prevention programs could be the solution. Recent knowledge in understanding molecular determinants of energy liver metabolism and new genetic markers offers new insights into the pathogenesis of CLD and HCC. The main rationale of the present issue is to provide a summary of recent insights into the inherited variants regulating lipid metabolism (steatohepatitis) and acquired mutation for early diagnosis of HCC, specifically focusing on the significance of antioxidant agents and genotyping tests as a cost-effectiveness tool for the prevention of liver disease. Several national healthy programs worldwide promote the daily use of antioxidant nutrients either for the prevention and/or as complementary and alternative medicines (CAM). This review could be advising for the planning of a large-scale clinical trial including a combination strategy of antioxidant agents and genotyping tests in patients with high risk of CLD.

Surgical management of chronic, unreduced posterior dislocation of the shoulder

Four patients with chronic posterior dislocation of the shoulder underwent surgical treatment after an average delay of 10 months from injury. They were examined clinically and radiographically at an average follow-up of 32 months. Treatment consisted of subscapularis tendon transfer (McLaughlin procedure) into the humeral defect in one case, transfer of the lesser tuberosity (McLaughlin modified procedure) in two cases, and in the fourth case-a patient with a 19-month missed dislocation and 50% humeral head lesion-a transposition of the coracoid process and conjoined tendon was performed. X-rays and CT scan excluded avascular necrosis or severe post-traumatic arthrosis. All patients achieved complete pain relief without limitation of daily or work activities. A slight limitation of anterior elevation and external rotation was present in all patients. Our results confirm that McLaughlin's original or modified procedure is suggested in cases of chronic, unreduced posterior dislocation of the shoulder (type I according to Randelli). The transposition of the coracoid process is a valid alternative to prosthesis and to autologous or homologous bone graft implants.
