Gastrointestinal transit after laparoscopic versus open colonic resection.

BACKGROUND: Multimodal rehabilitation with epidural analgesia, early oral nutrition and mobilization, and laxative use has decreased the duration of ileus after colonic surgery to about 2 days, as compared with the usual 3 to 5 days of rehabilitation required after open surgery and the slightly shorter time required with laparoscopic surgery. Gastrointestinal transit after colonic resection with laparoscopy or laparotomy was assessed. METHODS: In this study, 32 patients randomized to laparoscopic or open colonic resection received 4 MBq of 111indium diethylenetriamine pentaacetic acid, a tracer, at the end of surgery. Images of the abdomen were obtained 24 and 48 h postoperatively. An opaque abdominal dressing blinded care personnel and patients to the procedure. RESULTS: Defecation occurred on median day 2 postoperatively in both groups. At 48 h postoperatively, 53% of the tracer was excreted by patients in the laparoscopic group, as compared with 26% in the open group ( p > 0.05). CONCLUSION: Postoperative ileus and gastrointestinal transit normalized within 48 h after colonic resection in the patients who received multimodal rehabilitation. No significant difference was observed between the patients who underwent the laparoscopic procedure and those who underwent the open procedure.

Is urinary drainage necessary during continuous epidural analgesia after colonic resection?

BACKGROUND AND OBJECTIVES: Postoperative urinary retention may occur in between 10% and 60% of patients after major surgery. Continuous lumbar epidural analgesia, in contrast to thoracic epidural analgesia, may inhibit urinary bladder function. Postoperative urinary drainage has been common in patients with continuous epidural analgesia, despite the lack of scientific evidence for its indication after thoracic epidural analgesia. This study describes 100 patients who underwent elective colonic resection with 48 hours of continuous thoracic epidural analgesia and only 24 hours of urinary drainage. METHODS: This is a prospective, uncontrolled study with well-defined general anesthesia, postoperative analgesia, and nursing care programs in patients with a planned 2-day hospital stay, urinary catheter removal on the first postoperative morning, and epidural catheter removal on the second postoperative morning. Follow-up in the outpatient clinic was on days 8 and 30. RESULTS: Nine patients needed bladder recatheterization, 8 as a single procedure and 1 patient a second recatheterization with removal on day 7. This patient had urinary infection on day 10 and was readmitted for 5 days because of urosepsis and, subsequently, for cystitis and left-sided epididymitis. Three patients had uncomplicated urinary infection. No patients had urological complaints at 30 days follow-up (95% confidence limit, 0% to 3.6%). CONCLUSION: The low incidence of urinary retention (9%) and urinary infection (4%) suggests that routine bladder catheterization beyond postoperative day 1 may not be necessary in patients with ongoing continuous low-dose thoracic epidural analgesia.

Convalescence after colonic resection with fast-track versus conventional care.

BACKGROUND: Multi-modal rehabilitation programmes may improve early postoperative body composition, pulmonary function, exercise capacity, and reduce hospital stay. So far, no data are available on convalescence after discharge. AIM: The objectives were to compare convalescence data (fatigue, sleep, time to resume normal activities, and functional capabilities) and need for nursing care and contact to general practitioner with fast-track multi-modal rehabilitation compared with conventional care after colonic surgery. METHODS: Non-randomised, prospective controlled study in 30 consecutive patients undergoing fast-track rehabilitation with continuous epidural analgesia, enforced oral nutrition, mobilisation, planned early discharge, and 30 consecutive patients undergoing conventional care. Patients were interviewed preoperatively and 14 and 30 days postoperatively. RESULTS: Median hospital stay was 2 vs. 8 days in the fast-track vs. conventional care group, respectively (p < 0.01). Fourteen days postoperatively, total and mid-day sleep were increased in the conventional care group when compared with the fast-track group (p < 0.01). Fatigue was increased significantly at 14 days (p < 0.05) and throughout the study period compared with the fast-track group (p < 0.01). Similarly, ability to walking stairs, cooking, house keeping, shopping and walking outdoor was significantly less reduced at 14 days in the fast-track group, who also regained leisure activities earlier (p < 0.05). There was no significant difference between groups at 30 days or between need for nursing care and visits to general practitioners. Readmission for surgery-related events occurred more frequently (5 vs. 1 patient) in the fast-track group. CONCLUSION: Fast-track rehabilitation with early discharge after colonic surgery results in earlier resumption of normal activities with reduced fatigue and need for sleep postoperatively compared to conventional care, and without increased need for nursing care or visits to general practitioners. However, readmissions may occur more frequently.

[Accelerated rehabilitation after colon resection]. / Accelereret rehabilitering efter colonresektion.

INTRODUCTION: The stay in hospital after colonic resection is usually 7-12 days, with a complication rate of 20%. A multi-modal rehabilitation regimen, comprising epidural analgesia, early mobilisation, and oral nutrition, reduced the hospital stay to 2-3 days after colonic resection. METHODS: One hundred patients underwent elective colonic resection with a planned postoperative stay of two days in hospital and a regimen with epidural analgesia, oral nutrition, and mobilisation. Anaesthesia, the surgical technique, and nursing care programme were standardised. Postoperative follow-up visits were arranged for day 8 and day 30. RESULTS: The median age was 73 years. Forty patients were at high risk, ASA III-IV. Gastrointestinal function (defecation) occurred within 48 hours, except for five patients, and the median hospital stay was two days. The readmission rate was 18% with no acute, potentially lethal conditions. The total hospital stay was three days. None of the patients had cardiopulmonary complications, except for one patient, who died from cardiac failure 36 hours after surgery. Three patients had anastomotic dehiscence, two of whom were treated conservatively. CONCLUSION: The usual postoperative ileus, "medical complications", and hospital stay were reduced in high-risk patients undergoing colonic resection with a multi-modal rehabilitation programme. These results call for further comparative studies with conventional care programmes and laparoscopic colonic resection.

Influence of major surgery on the mannan-binding lectin pathway of innate immunity.

The mannan-binding lectin (MBL) pathway of complement activation is important in host defence against pathogens and possibly against cancer. We investigated the effect of major surgery on two central components of the MBL pathway; MBL and the MBL-associated serine protease MASP-2, and for comparison also measured the interleukin (IL)-6 and C-reactive protein (CRP) levels. Serial blood samples were obtained from patients belonging to two different cohorts. Cohort 1 comprised 60 patients undergoing open or laparoscopic colectomy for benign disease (n = 12) or colon cancer (n = 48). Cohort 2 comprised 27 patients undergoing elective, open surgery for colorectal cancer, and was included in order to cover blood sampling between days 2 and 6. As expected, the surgical stress induced a marked acute phase response, as evidenced by a large increase in IL-6 (18-fold) and CRP (13-fold) levels with maximum at 12 h and 2 days, respectively. However, in both cohorts the levels of MBL and MBL-associated serine protease 2 (MASP-2) were largely unaffected, except for a minor but significant increase around day 8 in cohort 1. The preoperative levels of IL-6 and CRP were correlated significantly in both cohorts (r = 0.71, P < 0.0001 and r = 0.65, P = 0.005, respectively). Preoperative MASP-2 correlated with preoperative CRP (r = 0.59, P = 0.001) and IL-6 (r = 0.55, P = 0.02) in cohort 2 only. In contrast to the marked effects on the levels of IL-6 and CRP, the surgery influenced only marginally the two proteins of the MBL pathway.

Impact of elective resection on plasma TIMP-1 levels in patients with colon cancer.

OBJECTIVE: Pre- and post-operative plasma tissue inhibitor of metalloproteinases-1 (TIMP-1) levels have a prognostic impact on patients with colorectal cancer. However, the surgical trauma may play an essential role in regulation of plasma TIMP-1 levels, which in turn may influence subsequent TIMP-1 measurements. PATIENTS AND METHODS: Consecutively, 48 patients with colon cancer (CC) and 12 patients with nonmalignant colonic disease were randomised to undergo elective laparoscopically assisted or open resection followed by fast track recovery. Plasma samples were collected just before and 1, 2 and 6 h after skin incision, and 1, 2, 8 and 30 days after surgery. TIMP-1 was determined concurrently in all samples by a validated ELISA method. RESULTS: Geometric mean preoperative TIMP-1 level was 142 ng/ml (range 54-559 ng/ml) among CC patients compared with 106 ng/ml (range 64-167 ng/ml) among patients with nonmalignant diseases (P<0.0001). TIMP-1 levels were decreased significantly 2 h after skin incision compared to the preoperative levels returning to preoperative levels at 6 h. A highly significant (P<0.0001) maximum level was observed 1 day after surgery and was decreasing to preoperative levels 30 days after surgery. Patients undergoing laparoscopically assisted or open resection had similar TIMP-1 levels at each time point. CONCLUSIONS: Major surgery has considerable impact on plasma TIMP-1 levels. Intra- and post-operative changes of plasma TIMP-1 levels are independent of the surgical approach, and resection for CC does not lead to a significant decrease of plasma TIMP-1 levels within 30 days postoperatively.

Influence of open versus laparoscopically assisted colectomy on soluble vascular endothelial growth factor (sVEGF) and its soluble receptor 1 (sVEGFR1).

INTRODUCTION: Minimal invasive colectomy may attenuate surgery-induced immunomodulation. This may in part be due to a reduced postoperative inflammation-mediated angiogenic stimulus directed by the proangiogenic factor VEGF and its neutralizing receptor VEGFR1. Thus, we evaluated perioperative plasma concentrations of soluble VEGF (sVEGF) and soluble VEGFR1 (sVEGFR1) in patients undergoing elective colectomy. METHODS: 60 consecutive patients were randomized to undergo laparoscopically assisted or open right or left sided colectomy. Blood samples were drawn preoperatively, intraoperatively and postoperatively until 30 days after the operation. Commercially available ELISA methods were used for determination of sVEGF and sVEGFR1. RESULTS: Patients with cancer (n = 48) had higher preoperative levels of sVEGF compared to patients with benign disease (n = 12) (p = 0.04), while there was no significant difference in sVEGFR1 levels (p = 0.053). Soluble VEGF (p < 0.0001) and sVEGFR1 (p < 0.0001) levels fluctuated intra- and postoperatively. However, the intra- and postoperative levels of sVEGF and sVEGFR1 were similar at all time points in patients undergoing laparoscopically assisted or open resection. CONCLUSION: Although significant fluctuation in sVEGF and sVEGFR1 concentrations during the perioperative period was shown, patients who underwent laparoscopically assisted resection had similar levels as patients who underwent open resection.

Normal gastrointestinal transit after colonic resection using epidural analgesia, enforced oral nutrition and laxative.

BACKGROUND: Postoperative ileus usually lasts for 2-5 days after colonic surgery and may contribute to discomfort and pulmonary complications. With multimodal rehabilitation (epidural analgesia, early oral nutrition and mobilization, and laxative) defaecation occurs 1-2 days after colonic surgery. The aim of this study was to assess the transit rate of the entire gastrointestinal tract after colonic resection with multimodal rehabilitation. METHODS: Gastrointestinal motility was assessed by means of a scintigraphic method in 12 patients undergoing open colonic resection with multimodal rehabilitation and in 12 matched healthy volunteers. After intragastric or oral administration of 4 MBq 111In-labelled diethylenetriamine penta-acetic acid, images of the abdomen were taken at 24 and 48 h with a double-headed gamma camera. RESULTS: Patient and volunteer demographics were similar. The first defaecation occurred a median of 1 day after operation in the patients. Some 57 per cent of the tracer was excreted in faeces of patients and 53 per cent in faeces of volunteers (P > 0.05) within 48 h, indicating rapid recovery of the entire gastrointestinal motility after colonic resection with multimodal rehabilitation. CONCLUSION: This study documents early normalization of the entire gastrointestinal motility assessed by an 111In scintigraphic method in patients undergoing open colonic resection with a multimodal rehabilitation programme.

A clinical pathway to accelerate recovery after colonic resection.

OBJECTIVE: To investigate the feasibility of a 48-hour postoperative stay program after colonic resection. SUMMARY BACKGROUND DATA: Postoperative hospital stay after colonic resection is usually 6 to 12 days, with a complication rate of 10% to 20%. Limiting factors for early recovery include stress-induced organ dysfunction, paralytic ileus, pain, and fatigue. It has been hypothesized that an accelerated multimodal rehabilitation program with optimal pain relief, stress reduction with regional anesthesia, early enteral nutrition, and early mobilization may enhance recovery and reduce the complication rate. METHODS: Sixty consecutive patients undergoing elective colonic resection were prospectively studied using a well-defined postoperative care program including continuous thoracic epidural analgesia and enforced early mobilization and enteral nutrition, and a planned 48-hour postoperative hospital stay. Postoperative follow-up was scheduled at 8 and 30 days. RESULTS: Median age was 74 years, with 20 patients in ASA group III-IV. Normal gastrointestinal function (defecation) occurred within 48 hours in 57 patients, and the median hospital stay was 2 days, with 32 patients staying 2 days after surgery. There were no cardiopulmonary complications. The readmission rate was 15%, including two patients with anastomotic dehiscence (one treated conservatively, one with colostomy); other readmissions required only short-term observation. CONCLUSION: A multimodal rehabilitation program may significantly reduce the postoperative hospital stay in high-risk patients undergoing colonic resection. Such a program may also reduce postoperative ileus and cardiopulmonary complications. These results may have important implications for the care of patients after colonic surgery and in the future assessment of open versus laparoscopic colonic resection.

Accelerated postoperative recovery programme after colonic resection improves physical performance, pulmonary function and body composition.

BACKGROUND: Postoperative organ dysfunction contributes to morbidity, hospital stay and convalescence. Multimodal rehabilitation with epidural analgesia, early oral feeding, mobilization and laxative use after colonic resection has reduced ileus and hospital stay. METHODS: Fourteen patients receiving conventional care (group 1) and 14 patients who had multimodal rehabilitation (group 2) were studied before and 8 days after colonic resection. Outcome measures included postoperative mobilization, body composition by whole-body dual X-ray absorptiometry, cardiovascular response to treadmill exercise, pulmonary function and nocturnal oxygen saturation. RESULTS: Defaecation occurred earlier (median day 1 versus day 4) and hospital stay was shorter (median 2 versus 12 days) in patients who had multimodal treatment. Lean body and fat mass decreased in group 1 but not in group 2. Exercise performance decreased by 44 per cent in group 1 but was unchanged in group 2. A postoperative increase in heart rate (HR) response to exercise was avoided in group 2. Pulmonary function decreased in group 1 but not in group 2. There was less nocturnal postoperative hypoxaemia in group 2. Cardiac demand-supply (HR/oxygen saturation ratio) increased in group 1 but not in group 2. CONCLUSION: Multimodal rehabilitation prevents reduction in lean body mass, pulmonary function, oxygenation and cardiovascular response to exercise after colonic surgery.
