Guidelines for Perioperative Care for Liver Surgery: Enhanced Recovery After Surgery (ERAS) Society Recommendations 2022.

BACKGROUND: Enhanced Recovery After Surgery (ERAS) has been widely applied in liver surgery since the publication of the first ERAS guidelines in 2016. The aim of the present article was to update the ERAS guidelines in liver surgery using a modified Delphi method based on a systematic review of the literature. METHODS: A systematic literature review was performed using MEDLINE/PubMed, Embase, and the Cochrane Library. A modified Delphi method including 15 international experts was used. Consensus was judged to be reached when >80% of the experts agreed on the recommended items. Recommendations were based on the Grading of Recommendations, Assessment, Development and Evaluations system. RESULTS: A total of 7541 manuscripts were screened, and 240 articles were finally included. Twenty-five recommendation items were elaborated. All of them obtained consensus (>80% agreement) after 3 Delphi rounds. Nine items (36%) had a high level of evidence and 16 (64%) a strong recommendation grade. Compared to the first ERAS guidelines published, 3 novel items were introduced: prehabilitation in high-risk patients, preoperative biliary drainage in cholestatic liver, and preoperative smoking and alcohol cessation at least 4 weeks before hepatectomy. CONCLUSIONS: These guidelines based on the best available evidence allow standardization of the perioperative management of patients undergoing liver surgery. Specific studies on hepatectomy in cirrhotic patients following an ERAS program are still needed.

Five-year Follow-up and Recurrence Rates Following Surgery for Acute and Chronic Pilonidal Disease: A Survey of 421 Cases.

OBJECTIVE: The aim of the present study was to investigate the outcomes of different treatment options for acute and chronic pilonidal disease in a single large cohort of patients. MATERIALS AND METHODS: Four hundred and twenty-one consecutive patients (171 with chronic disease and 250 with acute abscess formation) who underwent surgery between 2003 and 2012 were included in the present study. Primary outcomes included symptomatic recurrence, time to wound healing, and time off from work. The median follow-up was 5.3 years. RESULTS: In patients with acute abscess formation, the relapse rate was significantly higher (P = 0.0001) if they were treated with abscess excision (38.9%) compared with a wide local excision (13.3%). Time to relapse was significantly longer (P = 0.0205) in patients treated with wide local excision (median 7 vs 3 months), whereas time to wound healing and the days off from work were similar among groups. In chronic disease, the relapse rate was similar in patients treated with wide local excision followed by secondary wound healing (11.3%) when compared with patients treated with limited excision (27.6%) or wide excision with primary wound closure (26.8%). The time to wound healing was shortest in patients with primary wound closure following wide local excision, and the time off from work was not significantly different between groups. CONCLUSION: Wide local excision with secondary wound healing seems to be the favorable operation method for acute and chronic pilonidal disease.

Predictive risk factors for intra- and postoperative complications in 526 laparoscopic sigmoid resections due to recurrent diverticulitis: a multivariate analysis.

BACKGROUND: Laparoscopic sigmoid resection is a feasible and frequent operation for patients who suffer from recurrent diverticulitis. There is still an ongoing debate about the optimal timing for surgery in patients who suffer from recurrent diverticulitis episodes. In elective situations the complication rate for this procedure is moderate, but there are patients at high risk for perioperative complications. The few identified risk factors so far refer to open surgery. Data for the elective laparoscopic approach is rare. The objective of this study was to identify potential predictive risk factors for intra- and postoperative complications in patients who underwent laparoscopic sigmoid resection due to diverticular disease. METHODS: Uni- and multivariate analyses of a prospectively gathered database (1993-2006) were performed on a consecutive series of 526 patients who underwent laparoscopic sigmoid resection due to recurrent diverticulitis in a single institution. Patients were assessed for demographic data, operative indications, and intra- and postoperative complications. Altogether, we analyzed 17 potential risk factors to identify significant influence on the intra- and postoperative outcome, including timing of surgery. RESULTS: Statistical analysis of specific medical and surgical complications revealed anemia, previous myocardial infarction, heart failure, experience of the surgeon, and male gender, as independent predictive risk factors for postoperative complications. Patients older than age 75 years was the only independent risk factor for intraoperative complications in a multiple logistic regression model. Early elective surgery led to increased conversion rate but did not influence the postoperative complication rate. CONCLUSIONS: This large, single-center study provides first evidence of the significance of specific predictive risk factors for intra- and postoperative complications in laparoscopic sigmoid resection for diverticular disease.

A multivariate analysis of potential risk factors for intra- and postoperative complications in 1316 elective laparoscopic colorectal procedures.

OBJECTIVE: To identify predictive risk factors for intra- and postoperative complications in patients undergoing laparoscopic colorectal surgery. BACKGROUND DATA: In emergency situations or in elective open and laparoscopic colorectal surgery, there are many risk factors that should be recognized by the surgeon to reduce complications and initiate adequate treatment. Most available data, thus far, refer to open colorectal surgery and literature that focuses mainly on a laparoscopic approach is still rare. METHODS: Univariate and multivariate analyses of a prospectively gathered database (1993-2006) were performed on a consecutive series of patients (1316) undergoing laparoscopic colorectal surgery who were operated at a single institution (first referral center). Patients were assessed for demographic data, operative indications, type of resection, and intra- and postoperative complications. Altogether, we analyzed 20 potential risk factors to identify significant influence on the intra- and postoperative outcome. RESULTS: Significant risk factors that led to intraoperative complications consisted of age > or = 75 years and malignant neoplasia. Increased postoperative rate of surgical complications was significantly influenced by male gender, age > or = 75 years, American Society of Anesthesiology class > or = III, malignant neoplasia, and the experience of the surgeon. The analysis of specific medical postoperative complications revealed even more significant predictive risk factors. In addition, our analysis showed that specific risk factors predict specific complications such as postoperative bleeding, anastomotic leakage, and surgical site infections. The type of surgical procedure performed also influenced patient outcome. CONCLUSION: This large single center study provides the first evidence of the significance of predictive risk factors for intra- and postoperative complications in laparoscopic colorectal surgery.

Predictors of intra- and postoperative complications in laparoscopic colorectal surgery: results of an expert survey.

BACKGROUND: The decision which patient should undergo laparoscopic rather than open colorectal surgery depends on weighing its benefits against its complications. We explored which criteria prognosticate complications in a laparoscopic intervention by assembling experienced visceral surgeons' beliefs. METHODS: A two-round postal survey was conducted: 21 experts in laparoscopic surgery were contacted and asked to list (first round) and weigh (second round) indicators (scale 1-10) they believed predicted intra- or postoperative complications in patients undergoing laparoscopic colorectal surgery. Median ratings and interquartile ranges (IQRs) were calculated. Rates >or=6 and IQRs

Multidimensional analysis of learning curves in laparoscopic sigmoid resection: eight-year results.

PURPOSE: The number of operations to reach a plateau phase in colorectal laparoscopic surgery is still under debate. There are few publications reporting on multidimensional assessment of the learning curve, including operation time and complication and conversion rates. The purpose of this study was to define a multidimensional learning curve for sigmoid resection performed by two surgeons with experience in laparoscopic surgery. METHODS: Between 1993 and 2001 from a total of 715 laparoscopic colorectal procedures, two surgeons performed self-educated 338 sigmoid resections. Demographic data, indications for surgery, procedure performed, operation time, frequency and kind of complications, conversion rate, and days to discharge were recorded. The moving average method was used to demonstrate the change of the operation time. The cumulative sum technique was used to chart the changes in the conversion and complication rates. RESULTS: Surgeon A performed 199 and Surgeon B 139 sigmoid resections. The operation time decreased from 225 minutes to 169 minutes after approximately 90 operations for Surgeon A and from 270 minutes to 223 minutes after 110 operations for Surgeon B. Based on a decline in intraoperative complications and conversion rate, the steady state was reached after approximately 70 to 80 interventions for both surgeons. CONCLUSIONS: The assessment of a learning curve should not be limited to measurement of a decrease in operation time but should also include the conversion and complication rates. The cumulative sum technique and moving average method as proposed in this study seem appropriate to evaluate the learning curve in this clinical domain. Our findings might be especially useful for those planning training programs in laparoscopic surgery.
