RESUMO
BACKGROUND: Laparoscopic choledochal cyst excision (LCCE) in adult patients is not common. AIMS: The aim is to report our experience of LCCE in adult patients. PATIENTS AND METHODS: This study includes a retrospective review of twenty adult patients (age >18 years) with choledochal cyst (CC) who underwent LCCE by a single surgical team from February 2011 to April 2016. RESULTS: The mean age was 45.5 years. Nineteen (95%) patients had Type-I CC, and one patient (5%) had Type-IV CC (Todani's classification). Fifteen patients (75%) presented with pain in the abdomen, and five patients (25%) presented with jaundice and/or cholangitis. LCCE was successful in 16 (80%) patients, whereas four patients (20%) required conversion to open method. The reason for conversion was technical difficulty due to the initial learning curve, adhesion and inflammation. The mean blood loss, operation time and post-operative stay were 117.5 ml, 299.5 min and 8.15 days, respectively. Bilioenteric anastomosis leak and formation of pseudoaneurysm occurred in one patient (5%); this patient later died due to uncontrolled intra-abdominal haemorrhage. There were no remote complications during a mean follow-up of 17.2 months. CONCLUSION: LCCE in adult patients is safe and feasible, but bilioenteric anastomosis leak may have fatal consequences.
RESUMO
BACKGROUND: Postoperative pulmonary complication (PPC) is a serious complication after liver surgery and is a major cause of mortality and morbidity in the intensive care unit (ICU). Therefore, the early identification of risk factors of PPCs may help to reduce the adverse outcomes. OBJECTIVE: The aim of this retrospective study was to determine the predictors of PPCs in patients undergoing hepatic resection. DESIGN: Retrospective, observational. METHODS: The patients admitted after hepatic resection in the gastrosurgical ICU of our institute between October 2009 and June 2013 was identified. The ICU charts were retrieved from the database to identify patients who developed PPCs. A comparison of risk factors was made between the patients who developed PPC (PPC group) against the patients who did not (no-PPC group). RESULTS: Of 117 patients with hepatic resection, 28 patients developed PPCs. Among these, pneumonia accounted for 12 (42.8%) followed by atelectasis in 8 (28.5%) and pleural effusion in 3 (10.7%). Among the patients developing PPCs, 16 patients were over a 70-year-old (57.1%), 21 patients were smokers (75%) and 8 patients (28.5%) had chronic obstructive pulmonary disease (COPD). The requirement for blood transfusion and duration of mechanical ventilation were greater in the patients developing PPC (2000 ± 340 vs. 1000 ± 210 ml; 10 ± 4.5 vs. 3 ± 1.3 days). CONCLUSION: Old age, chronic smoking, COPD, increased blood product transfusion, increased duration of mechanical ventilation and increased length of ICU stay increased the relative risk of PPC, presence of diabetes and occurrence of surgical complications (leak, dehiscence, etc.) were independent predictive variables for the development of PPC.
