Abstract
Background
The present study aims to examine the feasibility and safety of a two-day hospital stay after laparoscopic colorectal resection (LCR) under an enhanced recovery after surgery (ERAS) pathway.
Methods
Between 2003 and 2010, 882 consecutive patients undergoing LCR were analyzed. Patients were grouped and analyzed according to whether their hospital stay was 2 days (group A) or longer (group B). Demographic, surgical, and postoperative data were compared. To identify independent predictive factors related to a short hospital stay, a multivariate analysis was also performed.
Results
Group A represented 10.3 % of this series (91 patients). There were no differences regarding age, gender, BMI, ASA, and previous abdominal surgeries between groups. Group A had a lower incidence of rectal cancer and anterior resections than group B (6.6 vs. 17.7 % [p = 0.006] and 14.3 vs. 23.4 % [p = 0.048]), respectively, and a lower mean operative time (170 min vs. 192 min; p = 0.002). Group A had a lower overall morbidity rate than group B (5.5 vs. 16.9 %; p = 0.004) and a lower incidence of surgery-related complications (5.5 vs. 14.9 %; p = 0.001). The overall conversion rate was 10 % (only one patient in group A required conversion), and the difference in conversion rate between groups was statistically significant (1.2 vs. 10.7 %; p = 0.003). Group A had a lower readmission rate (0 vs. 4.9 %; p = 0.089). Multivariate analysis showed that conversion, postoperative morbidity, and rectal prolapse were independently associated with the length of hospital stay.
Conclusions
A two-day hospital stay after LCR is safe and feasible under an ERAS pathway, without compromising the readmission or complication rate.
Introduction
Laparoscopic colorectal surgery is becoming the standard treatment for elective colorectal resection, increasing from 13.8 % in 2007 to 42.6 % in 2009 of all colorectal resections [1]. Although laparoscopic colorectal resection (LCR) has been associated with a short hospital stay and low morbidity, mean hospital stay rates reported vary from 4 to 15 days [2–4]. A shorter hospital stay following colorectal surgery has been recently achieved through enhanced recovery after surgery programs (ERAS) [5, 6]. With this enhanced recovery protocol, some authors have mentioned a mean hospital stay between 3.5 and 4.5 days [7–9] with a low morbidity rate. However, readmission rates reported are still high, reaching up to 8–30 % [10–12]. In recent years, there has been a renewed interest in evaluating fast-track (FT) laparoscopic colorectal surgery intending to shorten hospital stay with low morbidity and readmission rates. Therefore, the aim of the present study was to examine the feasibility and safety of a two-day hospital stay after LCR in a referral center from Argentina under an ERAS protocol. A secondary outcome was to determine variables associated with a prolonged hospital stay.
Methods
Patients and data collection
A prospectively maintained, practice-specific database was used to identify all patients who underwent laparoscopic colorectal surgery from January 2003 to December 2010 at the Hospital Italiano de Buenos Aires, Argentina. Outcomes were prospectively recorded in an institutional review board-approved database. Patients were grouped and analyzed according to whether their hospital stay was 2 days (group A) or longer (group B). Analyzed variables included age, gender, body mass index (BMI), American Society of Anesthesiologists (ASA) score, previous abdominal surgeries, preoperative diagnosis, operation performed, postoperative outcomes, and readmission and reoperation rates.
Conversion was defined according to Chang et al. [13] as: (1) the need to perform a conventional laparotomy in order to accomplish the procedure or (2) premature abdominal incision for colorectal dissection or vascular control. All patients were analyzed based on intention-to-treat, and converted patients were included.
Postoperative morbidity was stratified according to the Dindo–Clavien classification of complications [14]. Minor surgical morbidity was considered as grades 1, 2, and 3a, and major morbidity as grades 3b, 4, and 5. Postoperative complications were divided into surgical complications (i.e., wound infection, anastomotic leak, postoperative bleeding) and general complications (i.e., cardiovascular, deep venous thrombosis). Postoperative ileus was defined according to Chen et al. [15]: if two or more episodes of vomiting of more than 200 ml occurred in the absence of a bowel movement. Resolution of postoperative ileus was defined as passage of a bowel movement in the absence of abdominal distension, nausea, or emesis.
Surgical procedures
Preoperative mechanical bowel preparation was performed with Phosphoral for all patients. A single preoperative dose of antibiotics (oral ciprofloxacin 750 mg and intravenous ornidazole 1 g) was given. Intraoperative mechanical thromboprophylaxis was performed with intermittent pneumatic compression. Orogastric tubes were used intraoperatively and removed after surgery. Intra-abdominal drains were routinely used.
In right-sided tumors, a right colectomy was performed with the use of three ports placed at the umbilicus, the right upper quadrant, and the left iliac fossa. An alternative extra port was placed in the right iliac fossa depending on surgeon preference. Ileocolic vessels were ligated with the use of Hem-o-lok ligating clips, and the specimen was removed through a vertical midline incision above the umbilicus. An ileocolic anastomosis was performed with a continuous polypropylene 4/0 handsewn suture.
Four ports were used in left colectomy and anterior resection (umbilical, left upper quadrant, right iliac fossa, and left iliac fossa). Inferior mesenteric vessels were ligated with Hem-o-lok clips and the specimen was removed through a curved incision in the left iliac fossa or through a Pfannestiel incision, depending on surgeon preference. A colorectal anastomosis was performed with a double-stapling technique. A diverting stoma was routinely used in colorectal anastomosis located 6 cm or less from the anal verge.
Perioperative care protocol
An enhanced recovery program was used in all cases (Table 1), including preoperative bupivacaine spinal anesthesia, early oral feeding, active mobilization, and discharge on the second postoperative day under a standardized discharge criterion. Thromboprophylaxis was performed with enoxaparin (Clexane 40 mg s.c.) starting 12 h before operation and continued once a day until hospital discharge. Oral intake and mobilization were done under a standardized program, aiming at the normal intake of fluid and solid food on the first and second postoperative days, respectively. Urinary catheters were generally removed and mobilization was started the first morning after surgery. Postoperative analgesia was provided by intravenous ketorolac. Oral analgesia was started once the oral diet was tolerated. Dietary tolerance was defined as the tolerance of two meals without nausea or vomiting. Discharge criteria included the tolerance of fluids and soft diet, adequate oral analgesia, passage of flatus or stool, and patient’s willingness to leave the hospital with adequate home support. First and second outpatient visits were planned for postoperative days 7 and 21, respectively.

Statistical analysis
Group data of continuous variables were expressed by the mean ± standard deviation (SD). We used Student’s t test, the Mann–Whitney U test, or analysis of variance (ANOVA) for comparing means, when appropriate. Categorical variables were compared with the χ 2 test. Multivariate analysis by both logistic and multiple regression was used to identify independent variables associated with length of hospital stay, adjusting for possible confounders. Odds ratios with associated 95 % confidence intervals (CI) were calculated. Multivariate models included variables statistically associated with those in univariate analysis, as well as those considered to have clinical relevance in the primary outcome.
All statistics were two-tailed and a p value <0.05 was deemed significant. Statistical analysis was done with the software package NCSS 2007, PASS 2005, GESS 2066 (Hintze J, 2077, Kaysville, UT).
Results
There were 882 patients in the analyzed period. Mean age was 63.7 years old (±14.9), females accounted for 46.9 % of the patients, and the mean BMI was 26 kg/m2 (±4.4). Group A represented 10.3 % of the patients in this series (91 patients). Additional demographic characteristics are shown in Table 2. There were no differences regarding age, gender, BMI, ASA, and previous abdominal surgeries between groups. The most common diagnosis of the overall population was colon cancer/polyp (55.8 %), followed by rectal cancer (16.5 %) and diverticular disease (13 %). The intraoperative data are shown in Table 3. The most frequent operations performed were sigmoidectomy (n = 135, 15 %), left colectomy (n = 133, 15 %), right colectomy (n = 128, 14.5 %), high anterior resection (n = 74, 8.4 %), low anterior resection (n = 48, 5.4 %), ultra-low anterior resection (n = 76, 8.6 %), and abdominoperineal resection (APR) (n = 11, 1.2 %). Group A had a lower incidence of rectal cancer and anterior resections than group B (6.6 vs. 17.7 % [p = 0.006] and 14.3 vs. 23.4 % [p = 0.048], respectively), and a lower mean operative time (170 vs. 192 min; p = 0.002). Table 4 shows postoperative outcomes. The median hospital stay was 3 days and there were no postoperative deaths in this series. Regarding postoperative morbidity, the overall morbidity rate was 15.6 % (139 patients), but 68 % of affected patients (n = 94) had minor complications (Dindo–Clavien classification 1, 2, or 3a). There were 150 postoperative complications with 123 (13.9 %) surgical complications and 27 (3 %) general complications among 882 patients. The most common surgical complication was postoperative ileus (49 patients) followed by wound infection (20 patients). Compared to group B, group A had a lower overall morbidity rate (5.5 vs. 16.9 %, respectively; p = 0.004) and a lower incidence of surgery-related complications (5.5 vs. 14.9 %, respectively; p = 0.001). Postoperative ileus was more frequent in group B than in group A (6 vs. 0 %, respectively; p = 0.02). None of the patients (0 %) in group A had general complications, whereas 27 patients (3.4 %) in group B had them (p = 0.07). Univariate analyses showed that male gender, preoperative comorbidities, and ASA score III–IV were associated with higher incidence of postoperative complications.

CI confidence interval
The overall conversion rate in this series was 10 % (86 patients). Only one patient in group A required conversion; thus when compared with group B, group A had a lower incidence of conversion (1.2 vs. 10.7 %; p = 0.003). The overall readmission rate was 4.4 % (39 patients); there were no readmissions in group A. Although readmission rate in group A was lower than in group B (0 vs. 4.9 %) this difference had no statistical significance (p = 0.089). Another finding of the univariate analyses was that patients with BMI >30 and low anterior resection had a higher readmission rate (8.5 vs. 3.7 % [p = 0.049] and 12.5 vs. 4 % [p = 0.019], respectively). Thirty-seven patients underwent reoperation. None of the patients in group A required reoperation, whereas the reoperation rate in group B was 4.7 % (p = 0.035). Indications for reoperation were peritonitis in 12 patients (32 %), intestinal occlusion in 11 patients (29 %), postoperative bleeding in 6 patients (16 %), anastomotic leak in 4 patients (10 %), intra-abdominal abscess in 2 patients (5 %), acute laparotomy dehiscence in 1 patient (2 %), and intestinal ischemia 1 patient (2 %).
Multivariate analysis showed that conversion, postoperative morbidity, and rectal prolapse were independently associated with a 2-day hospital stay, after adjusting for age, gender, BMI <30, ASA III-IV, rectal polyp/cancer, anterior resection, operative time, and colonic perforation after colonoscopy (CPAC) (Table 5).

Discussion
Despite the fact that LCRs allow an earlier recovery and discharge from hospital, a short hospital stay has not been routinely achieved [10]. Moreover, some authors have reported short hospital stays after open colorectal surgery when combining fast-track or multimodal recovery programs. In this regard, Behrns et al. [16] and Delaney et al. [17] reported a mean hospital stay of 4.4 and 3.5 days, respectively, after open surgery. Basse et al. [7] pushed these results further and reported 2-day hospital stays in a randomized trial comparing open versus laparoscopic surgery, showing no differences between groups. However, morbidity and readmission rates reported reached up to 27 and 12 %, respectively. In accordance with these data, Andersen et al. [18] mentioned a decrease in the readmission rate from 20.1 to 11.3 % when comparing patients with a 2-day versus a 3-day planned hospital stay. On the other hand, the LAFA study compared postoperative outcomes in four groups (2 laparoscopic and 2 open colectomy groups with and without an FT program). The median hospital stay of patients undergoing laparoscopic surgery with FT care was shorter than the other groups (laparoscopic/FT: 5 days, open/FT: 7 days, laparoscopic/standard: 6 days, and open/standard: 7 days (p < 0.001). However, there were no differences among groups regarding postoperative morbidity and mortality, reoperation and readmission rates, and quality of life at 2 and 4 weeks. The authors concluded that the optimal operative treatment for patients requiring segmental colectomy for colon tumor resection is laparoscopic embedded in a FT program or accelerated recovery [19]. A recent report from Delaney et al. [10] mentioned an overall readmission rate of 8.5 %, with 5.4 and 7.7 % after a 2 and 3-day hospital stay, respectively, in a series of 118 patients treated laparoscopically. However, this represents a single-institution series and additional data are needed. In the same way, Levy et al. [20] reported a series of 10 patients who underwent LCR with a 23 h hospital stay and no readmissions.
The results presented in this study bring new evidence supporting feasibility and safety of short hospital stays following LCR. Our series of 882 patients shows a median hospital stay of 3 days, with 10 % of patients discharged within the first 48 h. Readmission rates were 0 % for patients discharged on the second postoperative day and 4.9 % for patients who stayed longer than 2 days. Moreover, patients discharged within 48 h after surgery had lower morbidity and reoperation rates. Of course early discharge does not determine a lower morbidity, reoperation, and readmission rates, and it is likely these findings are related to several variables, including patient factors and disease factors, surgical experience, and procedure-specific issues. However, it allows patients who are recovering well from surgery on the second postoperative day to have a better chance of not having postoperative complications. Thus, colorectal surgeons should try to identify these patients in order to provide optimal postoperative care with appropriate efficiency. Therefore, FT recovery programs and standardized discharge criteria are of the utmost importance.
In our series, patients discharged on the second postoperative day had a lower mean operative time, a lower incidence of rectal cancer, and hence, a lower incidence of anterior resection. There were no differences between groups A and B regarding high and ultra-low anterior resections (8.8 vs. 8.3 % [p = 0.9] and 4.4 vs. 9.1 % [p = 0.12], respectively). However, compared to group B, group A had a lower proportion of low anterior resections (5.9 vs. 1.1 % [p = 0.05], respectively), which were associated with a higher readmission rate in a subanalysis of these data. This higher readmission rate associated with low anterior resection could reflect potentially severe complications (e.g., anastomotic leaks), which usually have an asymptomatic course in patients with a diverting stoma, which is routinely performed in an ultra-low anterior resection. It is also worth mentioning that while group A had a higher proportion of rectal prolapse, CPAC, and endometriosis compared to group B, the small sample size makes it impossible to draw any conclusions from these numbers.
Multivariate analysis showed that after adjusting for confounding factors, conversion, postoperative morbidity, and rectal prolapse were independently associated with length of hospital stay. An important issue to consider when analyzing postoperative outcomes of LCR, is the impact of conversion on postoperative results. It is known that conversion is associated with prolonged operative time, increased morbidity, slower recovery, and prolonged hospital stay [21–23]. Senagore et al. [12], in a series of 181 laparoscopic sigmoidectomies with a conversion rate of 12.1 %, reported a mean hospital stay of 2.9 ± 1.2 days for laparoscopically completed cases versus 6.4 ± 1.4 days for converted cases. They did not, however, report the overall mean hospital stay. Overall, patients with complications often required additional pharmacological treatments or surgical procedures that determine a longer hospital stay. Regarding this issue, postoperative ileus has been identified as the most frequent surgical complication associated with delayed hospital discharge, and laparoscopy has been claimed to reduce postoperative ileus [15]. Interestingly, patients in group A had a lower incidence of postoperative ileus than patients in group B, and there was no association between postoperative ileus and the operation performed. Similar results were reported by Delaney et al. [10]. The small number of rectal prolapse cases makes it difficult to establish why rectal prolapse is associated with earlier hospital discharge. However, we can infer that this is determined by technical aspects of the operation, such as less dissection of the descending colon or the avoidance of unnecessary resections.
Finally, one important argument against fast-track recovery programs is associated with the necessity of home care nursing [24]. However, our study shows that no skilled nursing was required after early discharge following LCR when applying standardized perioperative care programs. Moreover, ERAS programs are often criticized for difficulty in assessing patient compliance [25], and this could be cited as a limitation of our study. Future institutional efforts will be required to oversee this critical aspect of perioperative care.
In conclusion, a two-day hospital stay after LCR is safe and feasible under an ERAS pathway. Patients fulfilling standardized criteria can be safely discharged on the second postoperative day with a low readmission and complication rate. Both conversion to open conventional surgery and postoperative morbidity, however, were associated with prolonged hospital stay.
