Management and 1-year outcomes of anastomotic leakage after elective colorectal surgery.

PURPOSE: To analyze different types of management and one-year outcomes of anastomotic leakage (AL) after elective colorectal resection. METHODS: All patients with anastomotic leakage after elective colorectal surgery with anastomosis (76/1,546; 4.9%), with the exclusion of cases with proximal diverting stoma, were followed-up for at least one year. Primary endpoints were as follows: composite outcome of one-year mortality and/or unplanned intensive care unit (ICU) admission and additional morbidity rates. Secondary endpoints were as follows: length of stay (LOS), one-year persistent stoma rate, and rate of return to intended oncologic therapy (RIOT). RESULTS: One-year mortality rate was 10.5% and unplanned ICU admission rate was 30.3%. Risk factors of the composite outcome included age (aOR = 1.08 per 1-year increase, p = 0.002) and anastomotic breakdown with end stoma at reoperation (aOR = 2.77, p = 0.007). Additional morbidity rate was 52.6%: risk factors included open versus laparoscopic reoperation (aOR = 4.38, p = 0.03) and ICU admission (aOR = 3.63, p = 0.05). Median (IQR) overall LOS was 20 days (14-26), higher in the subgroup of patients reoperated without stoma. At 1 year, a stoma persisted in 32.0% of patients, higher in the open (41.2%) versus laparoscopic (12.5%) reoperation group (p = 0.04). Only 4 out of 18 patients (22.2%) were able to RIOT. CONCLUSION: Mortality and/or unplanned ICU admission rates after AL are influenced by increasing age and by anastomotic breakdown at reoperation; additional morbidity rates are influenced by unplanned ICU admission and by laparoscopic approach to reoperation, the latter also reducing permanent stoma and failure to RIOT rates.

Laparoscopic cholecystectomy: do risk factors for a prolonged length of stay exist?

Gallstones are one of the most common morbidities in the world. Laparoscopic cholecystectomy is the gold standard for gallbladder stones' removal. Few studies focus on the existence of predictive factors aimed at facilitating cholecystectomy in a day surgery setting. The aim of this retrospective study was to identify clinical factors that could guide day-surgery laparoscopic cholecystectomy safety. The study included 985 consecutive patients who underwent elective laparoscopic cholecystectomy for gallstone disease between May 2006 and February 2015. Patients were divided into two groups: group A with a length of stay ≤ 2 days (922 patients); group B with a length of stay > 2 days (63 patients). Univariate analysis showed that age, sex and the presence of obesity, cardiological, and nephrological comorbidities had a higher likelihood of a longer hospital stay. The logistic regression model showed that only age was a significant predictor of a longer stay. No complication has reached the statistical significance of extending the length of stay in group B. Conversely, the presence of such comorbidities has influenced the hospitalization. Our results allow the identification of a category of patients at high risk of hospitalization within 1 or 2 days from treatment. Moreover, we reported that there is no complication specifically affecting the length of stay. Our findings support the idea that a prolonged length of stay is not linked to the surgical procedure but to the patient's comorbidities.

Is Routine Intraoperative Contrast-Enhanced Ultrasonography Useful During Whole Liver Transplantation?

BACKGROUND: Vascular complications following liver transplantation (LT) may result from technical deficiencies. Intraoperative diagnosis remains challenging but can prevent serious delayed complications. Intraoperative Doppler ultrasonography (IOUS) represents the gold standard for imaging, although it requires radiological skills. Contrast-enhanced ultrasonography has been reported during postoperative assessments, but never intraoperatively (CE-IOUS). The aim of this study was to assess the feasibility of routine CE-IOUS, to evaluate its impact on surgical strategy and its usefulness. METHODS: All 553 whole LTs performed in our tertiary centre between 01/2010 and 12/2014 were reviewed. We compared perioperative outcomes and long-term survival in IOUS (n = 370) versus CE-IOUS (n = 103) groups. Secondarily, the seven cases where the two imaging findings conflicted (CE+ Group) were matched 1:2 and compared with an exclusively IOUS procedure (CE- Group, n = 14) to assess the consequences of a specific CE-guided strategy. RESULTS: CE-IOUS assessments were successful in 100% of cases, without any adverse effects. Vascular complications and patient/graft survival rates were identical in the IOUS and CE-IOUS groups (p = 0.65, 0.95 and 0.86, respectively). CE-IOUS confirmed IOUS findings in 93% of cases (n = 96) and led to the realization of an additional procedure (median arcuate ligament lysis) and six conservative strategies despite poor arterial (n = 5) or venous flow (n = 1) under Doppler analysis. The CE+ and CE- groups presented statistically identical perioperative and long-term outcomes. CONCLUSION: This study demonstrated the feasibility of CE-IOUS during whole LT. However, we failed to demonstrate any advantages of CE-IOUS over IOUS. Therefore, IOUS currently remains the gold-standard imaging technique for the intraoperative assessment of vascular patency.
