Emergency laparoscopic ileo-colic resection and primary intracorporeal anastomosis for Crohn's acute ileitis with free perforation and faecal peritonitis: first ever reported laparoscopic treatment

INTRODUCTION

Laparoscopy for abdominal surgical emergencies is gaining increasing acceptance given the spreading of advanced laparoscopic skills among modern surgeons, as it may allow at the same time an accurate diagnosis and appropriate treatment of acute abdomen. The use of the laparoscopic approach also in case of diffuse peritonitis is now becoming accepted provided hemodynamic stability, despite the common belief in the past decades that such severe condition represented an indication for conversion to open surgery or an immediate contraindication to continue laparoscopy. Crohn's Disease (CD) is a rare cause of acute abdomen and peritonitis, only a few cases of CD acute perforations are reported in the published literature; these cases have always been approached and treated by open laparotomy.

CASE DESCRIPTION

We report on a case of a faecal peritonitis due to an acute perforation caused by a terminal ileitis in an undiagnosed CD. The patient underwent diagnostic laparoscopy followed by a laparoscopic ileo-colic resection and primary intracorporeal anastomosis, with a successful postoperative outcome.

CONCLUSIONS

Complicated CD has to be considered within the possible causes of small bowel non-traumatic perforation. Emergency laparoscopy with resection and primary intra-corporeal anastomosis can be feasible and may be a safe and effective minimally invasive alternative to open surgery even in case of faecal peritonitis, in selected stable patients and in presence of appropriate laparoscopic colorectal surgical skills and experience. To the best of our knowledge the present experience is the first ever reported case managed with a totally laparoscopic extended ileocecal resection with intracorporeal anastomosis in case of acutely perforated CD and diffuse peritonitis.

The effect of a postoperative quality improvement program on outcomes in colorectal surgery in a community hospital

PURPOSE

The aim of this study was to evaluate whether implementation of a comprehensive quality improvement program was associated with improved outcomes in patients undergoing oncological colorectal surgery in a non-academic, non-referral community hospital.

METHODS

The quality improvement program (QIP) was introduced in January 2011 and consisted of the following interventions: (1) avoidance of postoperative nonsteriodal anti-inflammatory drugs; (2) normovolemia was pursued pre- and postoperatively; (3) non-resectional surgery if possible, in patients over 80 with ASA 3 or 4 classification; and (4) a standardized, postoperative surveillance protocol was introduced, with CRP determination day 2 and 4, and if necessary subsequent abdominal CT with rectal contrast to reduce delay in diagnosis of complications. From a prospectively maintained database of 488 patients undergoing colorectal surgery between 2009 and 2014, postoperative outcomes of patients operated before and after implementation of the program were compared.

RESULTS

The severe complication rate (Clavien-Dindo >3b) decreased significantly (25.0 vs. 13.7 %; p < .001) after implementation of the QIP program. The mortality rate dropped from 8.7 to 2.6 % (p = .003). The percentage of anastomotic leakage was 9.6% before QIP implementation and 4.2% after (p = .013). Median length of hospital stay decreased from 9 (IQR 5-19) to 7 days (IQR 4-12) (p < .001). Multivariate analyses showed that surgery after implementation of the program was a strong independent predictor for less major complications (OR 0.54, 95 % CI 0.32-0.88).

CONCLUSIONS

A significant decrease in major complications and mortality was observed after introduction of a relative simple quality improvement program.

Risk factors for anastomotic leak and postoperative morbidity and mortality after elective right colectomy for cancer: results from a prospective, multicentric study of 1102 patients

BACKGROUND

Studies focused on postoperative outcome after oncologic right colectomy are lacking. The main objective was to determine pre-/intraoperative risk factors for anastomotic leak after elective right colon resection for cancer. Secondary objectives were to determine risk factors for postoperative morbidity and mortality.

METHODS

Fifty-two hospitals participated in this prospective, observational study (September 2011-September 2012), including 1102 patients that underwent elective right colectomy. Forty-two pre-/intraoperative variables, related to patient, tumor, surgical procedure, and hospital, were analyzed as potential independent risk factors for anastomotic leak and postoperative morbidity and mortality.

RESULTS

Anastomotic leak was diagnosed in 93 patients (8.4 %), and 72 (6.5 %) of them needed radiological or surgical intervention. Morbidity, mortality, and wound infection rates were 29.0, 2.6, and 13.4 %, respectively. Preoperative serum protein concentration was the only independent risk factor for anastomotic leak (p < 0.0001, OR 0.6 per g/dL). When considering only clinically relevant anastomotic leaks, stapled technique (p = 0.03, OR 2.1) and preoperative serum protein concentration (p = 0.004, OR 0.6 g/dL) were identified as the only two independent risk factors. Age and preoperative serum albumin concentration resulted to be risk factors for postoperative mortality. Male gender, pulmonary or hepatic disease, and open surgical approach were identified as risk factors for postoperative morbidity, while male gender, obesity, intraoperative complication, and end-to-end anastomosis were risk factors for wound infection.

CONCLUSIONS

Preoperative nutritional status and the stapled anastomotic technique were the only independent risk factors for clinically relevant anastomotic leak after elective right colectomy for cancer. Age and preoperative nutritional status determined the mortality risk, while laparoscopic approach reduced postoperative morbidity.

Is the intraoperative air leak test effective in the prevention of colorectal anastomotic leakage? A systematic review and meta-analysis

OBJECTIVE

The intra-operative air leak test (ALT) is a common intraoperative test used to identify mechanically insufficient anastomosis. This meta-analysis aims to determine whether ALT aids to the reduction of postoperative colorectal anastomotic leakage (CAL).

METHODS

A literature search was performed to select studies in acknowledged databases. Full text articles targeting ALT during colorectal surgery were included. Quality assessment, risk of bias, and the level-of-evidence of the inclusions were evaluated. ALT methodology, ALT(+) (i.e., leak observed during the test) rate, and postoperative CAL rate of the included studies were subsequently analyzed.

RESULTS

Twenty studies were included for analysis, in which we found substantial risks of bias. A lower CAL rate was observed in patients who underwent ALT than those did not; however, the difference was not significant (p = 0.15). The intraoperative ALT(+) rate greatly varied among the included studies from 1.5 to 24.7 %. ALT(+) patients possessed a significantly higher CAL rate than the ALT(-) patients (11.4 vs. 4.2 %, p < 0.001).

CONCLUSIONS

Based on the available evidence, performing an ALT with the reported methodology has not significantly reduced the clinical CAL rate but remains necessary due to a higher risk of CAL in ALT(+) cases. Unfortunately, additional repairs under current methods may not effectively decrease this risk. Results of this review urge a standardization of ALT methodology and effective methods to repair ALT(+) anastomoses.

Rectus sheath catheters provide equivalent analgesia to epidurals following laparotomy for colorectal surgery

Introduction Rectus sheath catheters (RSCs) are increasingly being used to provide postoperative analgesia following laparotomy for colorectal surgery. Little is known about their efficacy in comparison with epidural infusion analgesia (EIA). They are potentially better as they avoid the recognised complications associated with EIA. This study compares these two methods of analgesia. Outcomes include average pain scores, time to mobilisation and length of stay. Methods This was a 33-month single centre observational study including all patients undergoing elective open or laparoscopic-converted-to-open colorectal resection for both benign and malignant disease. Patients received either EIA or RSCs. Data were collected prospectively and analysed retrospectively. Results A total of 95 patients were identified. Indications for surgery, operation and complications were recorded. The mean time to mobilisation was significantly shorter in patients who had RSCs compared with EIA patients (2.4 vs 3.5 days, p<0.05). There was no difference in postoperative pain scores or length of stay. Conclusions RSCs provide equivalent analgesia to EIA and avoid the recognised potential complications of EIA. They are associated with a shorter time to mobilisation. Their use should be adopted more widely.

Is aortoiliac calcification linked to colorectal anastomotic leakage? A case-control study

BACKGROUND

Anastomotic leakage in bowel surgery remains a devastating complication. Various risk factors have been uncovered, however, high anastomotic leakage rates are still being reported. This study describes the use of calcification markers of the central abdominal arteries as a prognostic factor for colorectal anastomotic leakage.

METHODS

This case-control study includes clinical data from three different hospitals. Calcium volume and calcium score of the aortoiliac tract were determined by CT-scan analysis. Cases were all patients with anastomotic leakage after a left-sided anastomosis (n = 30). Three controls were randomly matched for each case. Only patients with a contrast-enhanced pre-operative CT-scan were included.

RESULTS

The measurements of the calcium score and calcium volume of the different trajectories showed that there was one significant difference with regard to the right external iliac artery. Multiple regression analysis showed a significant different negative odds ratio of the presence of calcium in the right external iliac artery.

CONCLUSION

This study demonstrates that calcium volume and calcium score of the aortoiliac trajectory does not correlate with the risk of colorectal anastomotic leakage after a left-sided anastomosis.

Comparison of bleeding risks related to venous thromboembolism prophylaxis in laparoscopic vs open colorectal cancer surgery: a multicenter study in Japanese patients

BACKGROUND

Venous thromboembolism is the most common preventable cause of hospital death. The objective of this study was to clarify risk factors for postoperative bleeding related to thromboprophylaxis after laparoscopic colorectal cancer surgery.

METHODS

The study was conducted at 23 Japanese institutions and included patients with colorectal cancer who underwent laparoscopic or open surgery followed by fondaparinux treatment. We performed a retrospective analysis from a prospectively maintained database. We used multivariate analyses to evaluate clinical risk factors for prophylaxis-related bleeding events.

RESULTS

After multivariate analysis, male gender, intraoperative blood loss of less than 25 mL, and a preoperative platelet count below 15 × 10⁴/μL were found to be independent risk factors in the laparoscopic surgery group. Only the preoperative platelet count was an independent risk factor in the open surgery group.

CONCLUSIONS

Different prophylactic treatments for postoperative venous thromboembolism may be necessary in laparoscopic vs open surgery for colorectal cancer.

Transanal total mesorectal excision: Towards standardization of technique

AIM: To describe the role of Transanal total mesorectal excision (TaTME) in minimally invasive rectal cancer surgery, to examine the differences in patient selection and in reported surgical techniques and their impacts on postoperative outcomes and to discuss the future of TaTME.

METHODS: MEDLINE (PubMed), EMBASE, and The Cochrane Library were systematically searched through the 1^st of March 2015 using a predefined search strategy.

RESULTS: A total of 20 studies with 323 patients were included. Most studies were single-arm prospective studies with fewer than 100 patients. Multiple transanal access platforms were used, and the laparoscopic approach was either multi- or single port. The procedure was initiated transanally or transabdominally. If a simultaneous approach with 2 operating surgeons was chosen, the operative time was significantly reduced.

CONCLUSION: TaTME was also associated with better TME specimens and a longer distal resection margin. TaTME is thus feasible in expert hands, but the learning curve and safety profile are not well defined. Long-term follow-up regarding anal function and oncological outcomes should be performed in the future.

Transanal tube placement for prevention of anastomotic leakage following low anterior resection for rectal cancer: a systematic review and meta-analysis

Purpose

Anastomotic leakage following low anterior resection (LAR) for rectal cancer is a serious complication that increases morbidity and mortality rates. Transanal tube placement may reduce postoperative anastomotic leakage rate by reducing intraluminal pressure and preventing fecal extrusion through the staple line. This meta-analysis evaluated the effectiveness of transanal tube placement to prevent anastomotic leakage after LAR for rectal cancer using a stapling technique.

Methods

A systematic review of the literature was consistent with the recommendations of the PRISMA (preferred reporting items for systematic reviews and meta-analyses) statement. Multiple comprehensive databases, including PubMed, Embase, Cochrane Library and KoreaMed, were searched. The main study outcomes were anastomotic leakage.

Results

Two randomized clinical trials and 4 nonrandomized studies involving 1,118 patients were included. Subgroup analyses of randomized clinical trials found that transanal tube placement had no effect on study outcomes. Meta-analysis of nonrandomized studies showed that transanal tube placement was associated with a lower incidence of anastomotic leakage (relative risk, 0.32; 95% CI, 0.15-0.67; I² = 0%).

Conclusion

Transanal tube placement may be effective in preventing or reducing the occurrence of anastomotic leakage after LAR for rectal cancer using a stapling technique. Randomized clinical trials with sufficient power are needed to confirm the benefit of transanal tube placement.

Prospective Study on the Incidence of Postoperative Venous Thromboembolism in Korean Patients with Colorectal Cancer

PURPOSE

Pharmacologic thromboprophylaxis is routinely recommended for Western cancer patients undergoing major surgery for prevention of venous thromboembolism (VTE). However, it is uncertainwhetherroutine administration of pharmacologic thromboprophylaxis is necessary in all Asian surgical cancer patients. This prospective study was conducted to examine the incidence of and risk factors for postoperative VTE in Korean colorectal cancer (CRC) patients undergoing major abdominal surgery.

MATERIALS AND METHODS

This study comprised two cohorts, and none of patients received perioperative pharmacologic thromboprophylaxis. In cohort A (n=400), patients were routinely screened for VTE using lower-extremity Doppler ultrasonography (DUS) on postoperative days 5-14. In cohort B (n=148), routine DUS was not performed, and imaging was only performed when there were symptoms or signs that were suspicious for VTE. The primary endpoint was the VTE incidence at 4 weeks postoperatively in cohort A.

RESULTS

The postoperative incidence of VTE was 3.0% (n=12) in cohort A. Among the 12 patients, eight had distal calf vein thromboses and one had symptomatic thrombosis. Age ≥ 70 years (odds ratio [OR], 5.61), ≥ 2 comorbidities (OR, 13.42), and white blood cell counts of > 10,000/μL (OR, 17.43) were independent risk factors for postoperative VTE (p < 0.05). In cohort B, there was one case of VTE (0.7%).

CONCLUSION

The postoperative incidence of VTE, which included asymptomatic cases, was 3.0% in Korean CRC patients who did not receive pharmacologic thromboprophylaxis. Perioperative pharmacologic thromboprophylaxis should be administered to Asian CRC patients on a risk-stratified basis.

Incisional and port-site hernias following robotic colorectal surgery

BACKGROUND

The association between extraction site location, robotic trocar size, and the incidence of incisional hernias in robotic colorectal surgery remain unclear. Laparoscopic literature reports variable rates of incisional hernias versus open surgery, and variable rates of trocar site hernias. However, conclusions from these studies are confusing due to heterogeneity in closure techniques and may not be generalized to robotic cases. This study evaluates the effect of extraction site location on incisional hernia rates, as well as trocar hernia rates in robotic colorectal surgery.

MATERIALS AND METHODS

A retrospective review of multiport and single incision robotic colorectal surgeries from a single institution was performed. Patients underwent subtotal, segmental, or proctocolectomies, and were compared based on the extraction site through either a muscle-splitting (MS) or midline (ML) incision. Hernias were identified by imaging and/or physical exam. Demographics and risk factors for hernias were assessed. Groups were compared using a multivariate logistic regression analysis.

RESULTS

The study included 259 colorectal surgery patients comprising 146 with MS and 113 with ML extraction sites. Postoperative computed tomograms were performed on 155 patients (59.8 %) with a mean follow-up of 16.5 months. The overall incisional hernia rate was 5.8 %. A significantly higher hernia rate was found among the ML group compared to the MS group (12.4 vs. 0.68 %, p < 0.0001). Of the known risk factors assessed, only increased BMI was associated with incisional hernias (OR 1.18). No trocar site hernias were found.

CONCLUSION

Midline extraction sites are associated with a significantly increased rate of incisional hernias compared to muscle-splitting extraction sites. There is little evidence to recommend fascia closure of 8-mm trocar sites.

Anastomotic leak in colorectal surgery: are 75 % preventable?

INTRODUCTION

Anastomotic leak (AL) is a significant cause of morbidity and mortality associated with complications of colorectal surgery. Furthermore, AL results in prolonged hospital stays and significant increase in costs of medical resources.

MATERIALS AND METHODS

In this study, we investigated the impact of anastomosis technique on the rate of anastomotic leak. The rate of leak was compared between two groups performing end-to-end (E-E) vs. side-to-end (S-E) anastomosis. The impact of various risk factors was also compared between the two groups.

RESULTS

There were 382 E-E and 363 S-E anastomoses after left colectomy or rectal resections. The anastomotic leak rate was 8.64 % using E-E compared to 1.93 % using S-E anastomosis technique (p < 0.001).

CONCLUSIONS

These results indicate that the rate of anastomotic leak after left colon and rectum resections could be significantly reduced utilizing S-E anastomosis technique.

Benefit of oral feeding as early as one day after elective surgery for colorectal cancer: oral feeding on first versus second postoperative day

The optimal timing of early oral intake after surgery has not been fully established. The objective of this study was to compare early oral intake at postoperative day 1 after resection of colorectal cancer with that of day 2 to identify the optimal timing for resumption of oral intake in such patients. Consecutive patients with colorectal cancer who underwent elective colorectal resection were separated into two groups. Sixty-two patients began a liquid diet on the first postoperative day (POD1 group) and 58 patients began on POD2 (POD2 group) and advanced to a regular diet within the next 24 hours as tolerated. As for gastrointestinal recovery, the first passage of flatus was experienced, on average, on postoperative day 3.1 ± 1.0 in the POD2 group and on day 2.3 ± 0.7 in the POD1 group. The first defecation was also significantly earlier in patients in the POD1 group than those in the POD2 group (POD 3.2 ± 1.2 versus 4.2 ± 1.4, respectively). No statistical difference was found between the two groups in terms of postoperative complications. Our results suggest that very early feeding on POD1 after colorectal resection is safe and feasible and that induced a quicker recovery of postoperative gastrointestinal movement in patients.

Need for simulation in laparoscopic colorectal surgery training

The dissemination of laparoscopic colorectal surgery (LCS) has been slow despite increasing evidence for the clinical benefits, with a prolonged learning curve being one of the main restrictions for a prompt uptake. Performing advanced laparoscopic procedures requires dedicated surgical skills and new simulation methods designed precisely for LCS have been established: These include virtual reality simulators, box trainers, animal and human tissue and synthetic materials. Studies have even demonstrated an improvement in trainees’ laparoscopic skills in the actual operating room and a staged approach to surgical simulation with a combination of various training methods should be mandatory in every colorectal training program. The learning curve for LCS could be reduced through practice and skills development in a riskfree setting.

Intestinal microbiota and anastomotic leakage of stapled colorectal anastomoses: A pilot study. Surg Endosc. 2016;30:2259-2265. [PMID: 26385781 PMCID: PMC4887536 DOI: 10.1007/s00464-015-4508-z]

Background

Anastomotic leakage (AL) after colorectal surgery is a severe complication, resulting in morbidity, reinterventions, prolonged hospital stay and, in some cases, death. Some technical and patient-related aetiological factors of AL are well established. In many cases, however, none of these factors seem to explain the occurrence of AL. Recent studies suggest that the intestinal microbiome plays a role in wound healing, diabetes and Crohn’s disease. The aim of this study was to compare the intestinal microbiota of patients who developed AL with matched patients with healed colorectal anastomoses.

Methods

We investigated the microbiome in the doughnuts collected from 16 patients participating in the C-seal trial. We selected eight patients who developed AL requiring reintervention and eight matched controls without AL. We analysed the bacterial 16S rDNA of both groups with MiSeq sequencing.

Results

The abundance of Lachnospiraceae is statistically higher (P = 0.001) in patient group who did develop AL, while microbial diversity levels were higher in the group who did not develop AL (P = 0.037). Body mass index (BMI) was also positively associated with the abundance of the Lachnospiraceae family (P = 0.022).

Conclusion

A correlation between the bacterial family Lachnospiraceae, low microbial diversity and anastomotic leakage, possibly in association with the BMI, was found. The relative abundance of the Lachnospiraceae family is possibly explained by the higher abundance of mucin-degrading Ruminococci within that family in AL cases (P = 0.011) as is similarly the case in IBD.

Assessment by Using a Water-Soluble Contrast Enema Study of Radiologic Leakage in Lower Rectal Cancer Patients With Sphincter-Saving Surgery

Purpose

This study evaluated the efficacy of a water-soluble contrast enema (WCE) in predicting anastomotic healing after a low anterior resection (LAR).

Methods

Between January 2000 and March 2012, 682 consecutive patients underwent a LAR or an ultra-low anterior resection (uLAR) and were followed up for leakage. Clinical leakage was established by using physical and laboratory findings. Radiologic leakage was identified by using retrograde WCE imaging. Abnormal radiologic features on WCE were categorized into four types based on morphology: namely, dendritic, horny, saccular, and serpentine.

Results

Of the 126 patients who received a concurrent diverting stoma, only two (1.6%) suffered clinical leakage due to pelvic abscess. However, 37 patients (6.7%) in the other group suffered clinical leakage following fecal diversion (P = 0.027). Among the 163 patients who received a fecal diversion, 20 showed radiologic leakage on the first WCE (eight with and 12 without a concurrent diversion); 16 had abnormal features continuously until the final WCE while four patients healed spontaneously. Eleven of the 16 patients (69%), by their surgeon's decision, underwent a stoma restoration based on clinical findings (2/3 dendritic, 3/4 horny, 5/7 saccular, 1/2 serpentine). After stoma reversal, only 2 of the 11 (19%) complained of complications related to the rectal anastomosis.

Conclusion

WCE is helpful for detecting radiologic leakage before stoma restoration, especially in patients suffering clinical leakage after an uLAR. However, surgeons appear to opt for stoma restoration despite the persistent existence of radiologic leakage in cases with particular features on the WCE.

The six-minute walk test as a measure of postoperative recovery after colorectal resection: further examination of its measurement properties

INTRODUCTION

Patients, clinicians and researchers seek an easy, reproducible and valid measure of postoperative recovery. The six-minute walk test (6MWT) is a low-cost measure of physical function, which is a relevant dimension of recovery. The aim of the present study was to contribute further evidence for the validity of the 6MWT as a measure of postoperative recovery after colorectal surgery.

METHODS

This study involved a sample of 174 patients enrolled in three previous randomized controlled trials. Construct validity was assessed by testing the hypotheses that the distance walked in 6 min (6MWD) at 4 weeks after surgery is greater (1) in younger versus older patients, (2) in patients with higher preoperative physical status versus lower, (3) after laparoscopic versus open surgery, (4) in patients without postoperative complications versus with postoperative complications; and that 6MWD (5) correlates cross-sectionally with self-reported physical activity as measured with a questionnaire (CHAMPS). Statistical analysis was performed using linear regression and Spearman's correlation. The COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist was used to guide the formulation of hypotheses and reporting of results.

RESULTS

One hundred and fifty-one patients who completed the 6MWT at 4 weeks after surgery were included in the analysis. All hypotheses tested for construct validity were supported by the data. Older age, poorer physical status, open surgery and occurrence of postoperative complications were associated with clinically relevant reduction in 6MWD (>19 m). There was a moderate positive correlation between 6MWD and patient-reported physical activity (r = 0.46).

CONCLUSIONS

This study contributes further evidence for the construct validity of the 6MWT as a measure of postoperative recovery after colorectal surgery. Results from this study support the use of the 6MWT as an outcome measure in studies evaluating interventions aimed to improve postoperative recovery.

Improved survival after an educational project on colon cancer management in the county of Stockholm--a population based cohort study

INTRODUCTION

Outcomes in rectal cancer have improved dramatically after the introduction of total mesorectal excision (TME). Recently, the TME concept has been transformed into that of complete mesocolic excision (CME) in an attempt to improve prognosis for patients with colon cancer.

PATIENTS AND METHODS

Multidisciplinary team (MDT) workshops including the CME concept were held annually between 2004 and 2008 at the Karolinska University Hospital. The workshops focused on preoperative staging, surgery and histopathology and included lectures and live surgery sessions. To compare survival before and after the "Stockholm Colon Cancer Project" all patients diagnosed with a right sided colon cancer between January 1, 2001 and December 31, 2003 (Group 1) and from January 1, 2006 until December 31, 2008 (Group 2) in Stockholm were identified from the Swedish ColoRectal Cancer Registry (SCRCR).

RESULTS

The proportion of patients having a tumour resection and the proportion having emergency surgery was higher in Group 1. There were more early tumours and more R0 resections in Group 2. Overall survival in all diagnosed patients and disease free survival after tumour resection was improved in the second time period.

DISCUSSION

Surgical teaching programmes may have an impact on the management and outcome in colon cancer. The exact impact from the "Stockholm Colon Cancer Project" cannot be established, however it is likely that it contributed to the improved survival.

Urinary tract infection after surgery for colorectal malignancy: risk factors and complications

BACKGROUND

Over 4% of patients undergoing colorectal surgery develop postoperative urinary tract infection (UTI).

METHODS

Using 2005 to 2012 American College of Surgeons National Surgical Quality Improvement Program data for 47,781 patients, we examined independent risk factors and complications associated with UTI using multivariate logistic regression.

RESULTS

Independent predictors of UTI included female sex (odds ratio [OR] 1.705, 95% confidence interval [CI] 1.508 to 1.928), open procedure (OR 1.419, 95% CI 1.240 to 1.624), rectal procedure (OR 1.267, 95% CI 1.105 to 1.453), age greater than 65 years (OR 1.322, 95% CI 1.151 to 1.519), nonindependent functional status (OR 1.609, 95% CI 1.299 to 1.993), steroid use (OR 1.524, 95% CI 1.116 to 2.080), higher anesthesia class, and longer operative time. Patients with UTI had longer hospital stays (7 vs 12 days), higher reoperation rates (11.9% vs 5.1%), and higher 30-day mortality (3.3% vs 1.7%). Postoperative UTI correlated with other complications, including sepsis, surgical site infections, and pulmonary embolism (P < .001).

CONCLUSIONS

Postoperative UTI in colorectal surgery patients correlates with increased morbidity and mortality. Patients who contract postoperative UTI may be more likely to develop multiple complications.

Mesh herniorrhaphy with simultaneous colorectal surgery: a case-matched study from the American College of Surgeons National Surgical Quality Improvement Program

BACKGROUND

The aim of this study is to evaluate the impact of concurrent mesh herniorrhaphy on short-term outcomes of colorectal surgery by using a large, nationwide database.

METHODS

Patients who underwent simultaneous ventral hernia repair (VHR) and colorectal surgery between 2005 and 2010 were identified from the American College of Surgeons National Surgical Quality Improvement Program. Patients who underwent VHR with mesh repair were case matched with patients who underwent VHR without mesh based on the type of colorectal procedure, diagnosis, and American Society of Anesthesiologists score.

RESULTS

Two hundred sixty-two patients who underwent VHR with mesh were case matched with 524 patients who underwent VHR without mesh. Mean operating time was significantly longer in patients who underwent VHR with mesh (195.8 ± 98.7 vs 164.3 ± 84.4 minutes, P < .001). Postoperative morbidity (P = .58), mortality (P = .27), superficial surgical site infection (SSI) (P = .14), deep SSI (P = .38), organ space SSI (P = .17), wound disruption (P > .99), reoperation (P = .48), and length of hospital stay (P = .71) were comparable between the groups.

CONCLUSION

The American College of Surgeons National Surgical Quality Improvement Program data suggest that VHR with mesh does not increase 30-day mortality, medical or surgical morbidity in colorectal surgery setting.

[Intestinal obstruction secondary to postoperative adhesion formation in abdominal surgery. Review]

The development of intestinal obstruction after upper and lower abdominal surgery is part of the daily life of each every surgeon. Despite this, there are very few good quality studies that allow enable assessment of the frequency of intestinal obstruction to be assessed, even although postoperative adhesions are the cause of considerable direct and indirect morbidity and its prevention can be considered a public health problem. And yet, in Mexico, at this time, there is no validated recommendation validated on the prevention of adhesions, or more particularly, in connection with the use of a variety of anti-adhesion commercial products which have been marketed for at least a decade. Intraperitoneal adhesions develop between surfaces without peritoneum of the abdominal organs, mesentery, and abdominal wall. The most common site of adhesions is between the greater omentum and anterior abdominal wall previous. Despite the frequency of adhesions and their direct and indirect consequences, just there is only one published a recommendation (from gynaecological literature), regarding peritoneal adhesion prevention. As regards of colorectal surgery, performed more than 250,000 colorectal resections are performed annually in the United States, and from 24% to 35% of them will develop a complication. The clinical and economic financial burden of these complications is enormous, and surgeries colorectal surgery been specifically highlighted as a potential point prevention point of surgical morbidity.

Outcomes for single-incision laparoscopic colectomy surgery in obese patients: a case-matched study

BACKGROUND

Single-incision laparoscopic surgery (SILS) is safe and feasible for benign and malignant colorectal diseases. SILS offers several patient-related benefits over multiport laparoscopy. However, its use in obese patients has been limited from concerns of technical difficulty, oncologic compromise, and higher complication and conversion rates. Our objective was to evaluate the feasibility and efficacy of SILS for colectomy in obese patients.

METHODS

Review of a prospective database identified patients undergoing elective colectomy using SILS from 2009 to 2014. They were stratified into obese (BMI ≥ 30 kg/m(2)) and non-obese cohorts (BMI < 30 kg/m(2)) and then matched on patient characteristics, diagnosis, and operative procedure. Demographic and perioperative outcome data were evaluated. The primary outcome measures were operative time, length of stay (LOS), and conversion, complication, and readmission rates for each cohort.

RESULTS

A total of 160 patients were evaluated-80 in each cohort. Patients were well matched in demographics, diagnosis, and procedure variables. The obese cohort had significantly higher BMI (p < 0.001) and ASA scores (p = 0.035). Operative time (176.9 ± 64.0 vs. 144.4 ± 47.2 min, p < 0.001) and estimated blood loss (89.0 ± 139.5 vs. 51.6 ± 38.0 ml, p < 0.001) were significantly higher in the obese. There were no significant differences in conversion rates (p = 0.682), final incision length (p = 0.088), LOS (p = 0.332), postoperative complications (p = 0.430), or readmissions (p = 1.000) in the obese versus non-obese. Further, in malignant cases, lymph nodes harvested (p = 0.757) and negative distal margins (p = 1.000) were comparable across cohorts.

CONCLUSIONS

Single-incision laparoscopic colectomy in obese patients had significantly longer operative times, but comparable conversion rates, oncologic outcomes, lengths of stay, complication, and readmission rates as the non-obese cohorts. In the obese, where higher morbidity rates are typically associated with surgical outcomes, SILS may be the ideal platform to optimize outcomes in colorectal surgery. With additional operative time, the obese can realize the same clinical and quality benefits of minimally invasive surgery as the non-obese.

Total mesorectal excision for rectal cancer with emphasis on pelvic autonomic nerve preservation: Expert technical tips for robotic surgery

The primary goal of surgical intervention for rectal cancer is to achieve an oncologic cure while preserving function. Since the introduction of total mesorectal excision (TME), the oncologic outcome has improved greatly in terms of local recurrence and cancer-specific survival. However, there are still concerns regarding functional outcomes such as sexual and urinary dysfunction, even among experienced colorectal surgeons. Intraoperative nerve damage is the primary reason for sexual and urinary dysfunction and occurs due to lack of anatomical knowledge and poor visualization of the pelvic autonomic nerves. The rectum is located concavely along the curved sacrum and both the ischial tuberosity and iliac wing limit the pelvic cavity boundary. Thus, pelvic autonomic nerve preservation during dissection in a narrow or deep pelvis, with adherence to the TME principles, is very challenging for colorectal surgeons. Recent developments in robotic technology enable overcoming these difficulties caused by complex pelvic anatomy. This system can facilitate better preservation of the pelvic autonomic nerve and thereby achieve favorable postoperative sexual and voiding functions after rectal cancer surgery. The nerve-preserving TME technique includes identification and preservation of the superior hypogastric plexus nerve, bilateral hypogastric nerves, pelvic plexus, and neurovascular bundles. Standardized procedures should be performed sequentially as follows: posterior dissection, deep posterior dissection, anterior dissection, posterolateral dissection, and final circumferential pelvic dissection toward the pelvic floor. In future perspective, a structured education program on nerve-preserving robotic TME should be incorporated in the training for minimally invasive surgery.

Anastomotic reinforcement with omentoplasty following gastrointestinal anastomosis: A systematic review and meta-analysis

Anastomotic leak is a potentially devastating complication following gastrointestinal anastomosis. Some surgeons believe that reinforcing the anastomosis with omentum reduces the incidence and severity of anastomotic leak. A comprehensive electronic search of EMBASE, Medline, Web of Science and Cochrane databases was performed. Pooled odds ratios (POR) were calculated for discrete variables. There were six studies investigating esophageal anastomosis and 3 studies investigating colorectal anastomosis identified by the literature search. A total of 2296 patients were included, 1073 with omentoplasty and 1223 without. In esophageal surgery omentoplasty significantly reduced the rate of anastomotic leak (2.9% vs 10.5% (POR = 0.28; 95% CI = 0.17 to 0.47; P < 0.0001), but there was no significant effect upon in-hospital mortality (2.3% vs. 2.5%; POR = 0.911 [95% CI 0.439-1.887]; P = 0.802) or anastomotic stricture between the two groups (6.6% vs 9.1%; POR = 0.842 [95% CI 0.331 to 2.145]; P = 0.720). In colorectal surgery there was no significant difference in anastomotic leak rate (5.0% vs 8.4%; POR: 0.50; 95% CI 0.21 to 1.17) or in-hospital mortality (4.2% vs 4.1%; POR: 0.90; 95% CI 0.34 to 2.41). The results of this analysis show that omentoplasty significantly reduced the rate of anastomotic leak following esophageal anastomosis but these results were not observed in colorectal anastomosis. Omentoplasty could be used as an adjunct technique to reduce the incidence of anastomotic leak in oesophageal anastomosis.

Laparoscopic Versus Open Colorectal Resection Within Fast Track Programs: An Update Meta-Analysis Based on Randomized Controlled Trials

The objective of the study was to assess the safety and efficacy of laparoscopic colorectal surgery by comparing open operation within fast track (FT) programs. The Cochrane Library, PubMed, Embase and Chinese Biological Medicine Database were searched to identify all available randomized controlled trials (RCTs) comparing laparoscopic with open colorectal resection within FT programs. A total of seven RCTs were finally included, enrolling 714 patients with colorectal cancer: 373 patients underwent laparoscopic surgery and FT programs (laparoscopic/FT group) and 341 patients received open operation and FT programs (open/FT group). Postoperative hospital stay (weighted mean difference (WMD): 0.66; 95% CI: 0.27 - 1.04; P < 0.05), total hospital stay (WMD: 1.46; 95% CI: 0.40 - 2.51; P < 0.05) and overall complications (RR: 1.31; 95% CI: 1.12 - 1.54; P < 0.05) were significantly lower in laparoscopic/FT group than in open/FT group. However, no statistically significant differences on mortality (risk ratio (RR): 2.26; 95% CI: 0.62 - 8.22; P = 0.21), overall surgical complications (RR: 1.19; 95% CI: 0.94 - 1.51; P = 0.15) and readmission rates (RR: 1.33; 95% CI: 0.79 - 2.22; P = 0.28) were found between both groups. The laparoscopic colorectal surgery combined with FT programs shows high-level evidence on shortening postoperative and total hospital stay, reducing overall complications without compromising patients’ safety.

Risk factors for prolonged ileus following colon surgery. Surg Endosc. 2016;30:603-609. [PMID: 26017914 DOI: 10.1007/s00464-015-4247-1]

BACKGROUND

Prolonged ileus is one of the most common postoperative complications after colorectal surgery. We sought to investigate the predictors of prolonged ileus following elective colon resections procedures.

METHODS

The national participant user files of NSQIP databases were utilized to examine the clinical outcomes of patients undergoing elective colon resection during 2012-2013. Multivariate regression analysis was performed to investigate predictors of prolonged ileus. Prolonged ileus was defined as no return of bowel function in 7 days.

RESULTS

We sampled a total of 27,560 patients who underwent colon resections; of these, 3497 (12.7%) patients had prolonged ileus. Patients with ileocolonic anastomosis (ICA) had a significantly higher rate of prolonged ileus compared to patients with colorectal anastomosis (CRA) (15 vs. 11.5%, AOR 1.25, P < 0.01). Prolonged ileus was significantly associated with intra-abdominal infections (13 vs. 2.8%, AOR 2.56, P < 0.01) and anastomotic leakage (12 vs. 2.4%, AOR 2.50, P < 0.01). Factors such as preoperative sepsis (AOR 1.63, P < 0.01), disseminated cancer (AOR 1.24, P = 0.01), and chronic obstructive pulmonary disease (AOR 1.27, P = 0.02) were associated with an increased risk of prolonged ileus, whereas oral antibiotic bowel preparation (AOR 0.77, P < 0.01) and laparoscopic surgery (AOR 0.51, P < 0.01) are associated with decreased prolonged ileus risk.

CONCLUSIONS

Prolonged ileus is a common condition following colon resection, with an incidence of 12.7%. Among colon surgeries, colectomy with ICA resulted in the highest rate of postoperative prolonged ileus. Prolonged ileus is positively associated with anastomotic leak and intra-abdominal infections; thus, a high index of suspicion must be had in all patients with prolonged postoperative ileus.

An update

Intraoperative peripheral nerve injury during colorectal surgery procedures is a potentially serious complication that is often underestimated. The Trendelenburg position, use of inappropriately padded armboards and excessive shoulder abduction may encourage the development of brachial plexopathy during laparoscopic procedures. In open colorectal surgery, nerve injuries are less common. It usually involves the femoral plexus associated with lithotomy position and self-retaining retractor systems. Although in most cases the recovery is mostly complete, treatment consists of physical therapy to prevent muscular atrophy, protection of hypoesthesic skin areas and analgesics for neuropathic pain. The aim of the present study is to review the incidence, prevention and management of intraoperative peripheral nerve injury.

Caecal tumor biopsy with a rigid sigmoidoscope - Ileorectal intussusception

INTRODUCTION

Ileorectal intussusception is a rare condition in adults in which the distal ileum, caecum, variable lengths of ascending and transvers colon, and associated mesentery invaginate into the rectum.

PRESENTATION OF CASE

We present the case of a 56 year old man who presented to our hospital for investigation of vague symptoms including small volumes of bright red rectal bleeding and colicky abdominal pain. He was found on CT scanning to have an extensive ileorectal intussusception and extensive liver metastasis. An emergency laparotomy was performed due to the concern of bowel ischaemia. No evidence of bowel ischaemia was found. The intussusceptum was carefully reduced and an extended right hemicolectomy with a primary anastomosis was performed. The patient recovered well and was discharged home six days post operatively.

DISCUSSION

Intussusceptions are rare in the adult population. They may not present with the classical triad of crampy abdominal pain, vomiting, and bloody stools and radiological imaging plays a key role in diagnosis. Intussusception in adults is usually secondary to malignancy and operative management needs to take into account the risk of upstaging the disease. In the face of pre-existing metastasis, preserving bowel length should be considered; however, there is no high level evidence to guide decision-making.

CONCLUSION

Intussusception is a diagnosis that needs to be considered in the adult population. Diagnosis largely depends on radiological imaging, especially CT scanning. The operative management is variable and should be determined on a case by case basis.

An Open-Label Prospective Randomized Controlled Trial of Mechanical Bowel Preparation vs Nonmechanical Bowel Preparation in Elective Colorectal Surgery: Personal Experience

Over the last two decades, preoperative mechanical bowel preparation for elective colorectal surgery has been criticized. Yet, many surgeons are still in favor of its use simply because of the belief that it achieves better clearance of the colonic fecal load. The objective of this study is to compare the outcome with regard to patient compliance and postoperative complications following elective colorectal surgery between two groups of patients, one with bowel prepared mechanically and the other by nonmechanical means. This open-label prospective randomized controlled trial was conducted in a high-volume tertiary government referral hospital of Kolkata over a period of 3 years. It included 71 patients, divided into two groups, admitted for elective colorectal resection procedures in one surgical unit. Both methods of bowel preparation were equally well tolerated, and there was no statistically significant difference in the incidence of postoperative complications or mortality between the two groups.

To Drain or Not to Drain after Colorectal Cancer Surgery

Prophylactic drainage of abdominal cavity after GI surgery has been widely practiced. The most important signal function of prophylactic drain is to detect early complications. But the same drains could be the cause of some of the complications. Although there is a considerable theoretical and practical evidences in favor of drainage, the dispute about "to drain or not to drain" the peritoneal cavity after elective colorectal surgery remains open. Unfortunately, the principle of drainage is not based on any scientific data. During the last three decades, surgeons have made efforts to investigate the value of prophylactic drainage after colorectal surgery. However, the results of trials are contradictory due to lack of quality and/or statistical power and therefore do not provide an answer to the clinical question. A systematic review of studies suggests that there is insufficient evidence for routine use of drain after colorectal surgery. Despite evidence-based data questioning prophylactic drainage of abdominal cavity in many instances, most surgeons around the world continue to use drains on a routine basis until now. There are strong evidences in literature in favor of no apparent benefit of drainage for supra-peritoneal anastomoses; however, there is still controversies regarding drainage of infra-peritoneal rectal anastomoses.

Laparoscopic colostomy for acute left colon obstruction caused by diverticular disease in high risk patient: A case report

INTRODUCTION

The colostomy is often necessary in complicated divertcular disease. The laparoscopic colostomy is not widely used for the treatment of complicated diverticular disease. Its use in patients with high operative risk is still on debate. The aim of this case report was to present the benefits of laparoscopic colostomy in patients with high peri-and postoperative risk factors.

PRESENTATION OF CASE

We present a case of 76-year-old female admitted to emergency unit for left colonic obstruction. The patient had a past history of liver cirrhosis HCV-related with a severe malnutrition, hypertrophic cardiomyopathy, diverticular disease, hiatal ernia, previous appendectomy. Patient was classified according to their preoperative risk ASA 3 (classification of the American society of Anestesia-ASA score). Contrast-enhanced abdominal CT revealed a marked thickening in the sigmoid colon and a marked circumferential stenosis in the sigmoid colon in absence of neoplasm, and/or abscess. The laparoscopic procedure is proposed as first intention.

DISCUSSION

The operation time was 50min, and the hospital stay was 4 days. Post operative complications grade I according to the Clavien Dindo Classification.

CONCLUSIONS

Laparoscopic colostomy is safe and feasible procedure in experienced hands. It is associated with low morbidity and short stay in hospital and should be considered a good alternative to a laparotomy.

Safety and feasibility of laparoscopic colo-rectal surgery for cancer at a tertiary center in a developing country: Egypt as an example. J Egypt Natl Canc Inst. 2015;27:91-95. [PMID: 25921235 DOI: 10.1016/j.jnci.2015.03.005]

BACKGROUND

Laparoscopic colectomy has been shown to have significant short- and long-term benefits compared to open approach. The incorporation of laparoscopy in developing countries is challenging, due to the high costs of equipment and lack of expertise. The aim of this study was to evaluate the safety and feasibility of laparoscopic colorectal surgery for cancer that could be performed in developing countries under different circumstances in developed countries.

METHODS

Thirty-seven patients (23 males and 14 females) with colorectal cancer with a median age of 46 years (39-72) have been enrolled for laparoscopic colo-rectal surgery in a tertiary center in Egypt (South Egypt Cancer Institute) with the trend of reuse of some disposable laparoscopic instruments.

RESULTS

The median operative time was 130 min (95-195 min). The median estimated blood loss was 70 ml (30-90 ml). No major intra-operative complications have been encountered. Two cases (5.5%) have been converted because of local advancement (one case) and bleeding with unavailability of vessel sealing device at that time (one case). The median time for passing flatus after surgery was 36 h (12-72 h). The median hospital stay was 4.8 days (4-7 days). The peri-operative period passed without events. Pathologic outcome revealed that the median number of retrieved lymph nodes was 14 (range 9-23 lymph node) and all cases had free surgical margin.

CONCLUSION

Laparoscopic colorectal surgery for cancer in developing countries could be safe and feasible. Safe reuse of disposable expensive parts of some laparoscopic instruments could help in propagation of this technique in developing countries.

Costs of complications after colorectal cancer surgery in the Netherlands: Building the business case for hospitals. Eur J Surg Oncol. 2015;41:1059-1067. [PMID: 25960291 DOI: 10.1016/j.ejso.2015.03.236]

BACKGROUND

Healthcare providers worldwide are struggling with rising costs while hospitals budgets are under stress. Colorectal cancer surgery is commonly performed, however it is associated with a disproportionate share of adverse events in general surgery. Since adverse events are associated with extra hospital costs it seems important to explicitly discuss the costs of complications and the risk factors for high-costs after colorectal surgery.

METHODS

Retrospective analysis of clinical and financial outcomes after colorectal cancer surgery in 29 Dutch hospitals (6768 patients). Detailed clinical data was derived from the 2011-2012 population-based Dutch Surgical Colorectal Audit database. Costs were measured uniform in all participating hospitals and based on Time-Driven Activity-Based Costing.

FINDINGS

Of total hospital costs in this study, 31% was spent on complications and the top 5% most expensive patients were accountable for 23% of hospitals budgets. Minor and severe complications were respectively associated with a 26% and 196% increase in costs as compared to patients without complications. Independent from other risk factors, ASA IV, double tumor, ASA III, short course preoperative radiotherapy and TNM-4 stadium disease were the top-5 attributors to high costs.

CONCLUSIONS

This article shows that complications after colorectal cancer surgery are associated with a substantial increase in costs. Although not all surgical complications can be prevented, reducing complications will result in considerable cost savings. By providing a business case we show that investments made to develop targeted quality improvement programs will pay off eventually. Results based on this study should encourage healthcare providers to endorse quality improvement efforts.

Adjuvant chemotherapy for the perineural invasion of colorectal cancer

BACKGROUND

To evaluate the association of perineural invasion (PNI) with outcomes in patients after colorectal resection of colorectal cancer (CRC) and to assess the effect of PNI on the response to adjuvant chemotherapy.

PATIENTS AND METHODS

Data were retrospectively reviewed for 178 patients with consecutive stages I-III CRC who underwent curative surgery between January 1999 and December 2004. PNI data were examined, and the overall survival (OS) and disease-free survival rates were analyzed.

RESULTS

PNI was detected in 36 of 178 patients (20%) and positively correlated with lymphatic invasion (P = 0.020), venous invasion (P = 0.037), and the incidence of metastasis or recurrence (P = 0.029). Five-year disease-free survival was 46% and 68% (P < 0.001) and the 5-y OS was 64% and 80% (P < 0.001) for patients with and without PNI, respectively. In stage III CRC, multiple regression analysis identified PNI as a strong negative prognostic factor of OS; among PNI-positive patients, median OS with adjuvant chemotherapy was almost twofold higher than that without adjuvant chemotherapy (6 versus 2.8 y; P = 0.017).

CONCLUSIONS

PNI was a poor predictor of survival among patients with stage III CRC, and adjuvant chemotherapy may attenuate the adverse effects of PNI on survival.

Long-term efficacy of endoscopic vacuum therapy for the treatment of colorectal anastomotic leaks

BACKGROUND

Anastomotic leaks are a severe complication after colorectal surgery. We aimed to evaluate the long-term efficacy of endoscopic vacuum therapy for their treatment.

METHODS

Retrospective review of a series of post-surgical colorectal leaks treated with endoscopic vacuum therapy, with minimum follow-up of 1 year. Generalized peritonitis or haemodynamic instability was considered contraindication to endoscopic treatment.

RESULTS

Endoscopic vacuum therapy was applied in 14 patients with colorectal leak, in 2 cases complicated by recto-vaginal fistula. Overall success rate was 79%, favoured by early beginning of treatment (90%) and presence of a stoma (100%) and no preoperative radiotherapy (86%). Median duration of treatment was 12.5 sessions (range 4-40). Median time for complete healing was 40.5 days (range 8-114), for a median cost of treatment of 3125 Euros. No complication related to endoscopic vacuum therapy was observed. Further surgery was required in 3 cases.

CONCLUSION

Endoscopic vacuum therapy is a safe treatment for post-surgical leaks, with high success rates.

Even modest hypoalbuminemia affects outcomes of colorectal surgery patients

BACKGROUND

A small decrease in the serum albumin from the normal level is a common condition in preoperative laboratory tests of colorectal surgery patients; however, there is limited data examining these patients. We sought to identify outcomes of such patients.

METHODS

The National Surgical Quality Improvement Program database was used to evaluate all patients who had modest levels of hypoalbuminemia (3 ≤ serum albumin < 3.5 g/dL) before colorectal resection from 2005 to 2012. Multivariate analysis using logistic regression was performed to quantify complications associated with modest hypoalbuminemia.

RESULTS

A total of 108,898 patients undergoing colorectal resection were identified, of which 16,962 (15.6%) had modest levels of preoperative hypoalbuminemia. Postsurgical complications significantly associated (P < .05) with modest hypoalbuminemia were as follows: hospitalization more than 30 days (adjusted odds ratio [AOR], 1.77), deep vein thrombosis (AOR, 1.64), unplanned intubation (AOR, 1.42), ventilator dependency for more than 48 hours (AOR, 1.30), and wound disruption (AOR, 1.22).

CONCLUSIONS

Modest hypoalbuminemia is a common preoperative condition in patients undergoing colorectal resection. Our analysis demonstrates that modest hypoalbuminemia has associations with increased postoperative complications, especially pulmonary complications.

Surgical outcomes of Korean ulcerative colitis patients with and without colitis-associated cancer

AIM: To determine the clinicopathologic characteristics of surgically treated ulcerative colitis (UC) patients, and to compare the characteristics of UC patients with colitis-associated cancer (CAC) to those without CAC.

METHODS: Clinical data on UC patients who underwent abdominal surgery from 1980 to 2013 were collected from 11 medical institutions. Data were analyzed to compare the clinical features of patients with CAC and those of patients without CAC.

RESULTS: Among 415 UC patients, 383 (92.2%) underwent total proctocolectomy, and of these, 342 (89%) were subjected to ileal pouch-anal anastomosis. CAC was found in 47 patients (11.3%). Adenocarcinoma was found in 45 patients, and the others had either neuroendocrine carcinoma or lymphoma. Comparing the UC patients with and without CAC, the UC patients with CAC were characteristically older at the time of diagnosis, had longer disease duration, underwent frequent laparoscopic surgery, and were infrequently given preoperative steroid therapy (P < 0.001-0.035). During the 37 mo mean follow-up period, the 3-year overall survival rate was 82.2%.

CONCLUSION: Most Korean UC patients experience early disease exacerbation or complications. Approximately 10% of UC patients had CAC, and UC patients with CAC had a later diagnosis, a longer disease duration, and less steroid treatment than UC patients without CAC.

Anastomotic leakage after laparoscopic single-port sigmoid resection: combined transanal and transabdominal minimal invasive management

BACKGROUND

Laparoscopic colorectal surgery has become the gold standard in the therapy of benignant and malignant colorectal pathologies. Anastomotic leakage is still a reason for laparotomy; applying a diverting stoma or performing a Hartman's procedure is common [1, 2]. Laparoscopic treatment of an early-detected anastomotic leakage is suggested from other authors [3, 4]. In our video we demonstrate a combined minimal invasive transabdominal and transanal treatment concept in patients with early-detected anastomotic leakage.

METHODS

Two consecutive patients developing an anastomotic leakage after single-port laparoscopic sigmoid resection for stage II/III diverticulitis (Hanson & Stock) were treated with a combined minimal invasive approach. Anastomotic leakage was diagnosed by triple contrast computed tomography on postoperative day 4 in patient one and on postoperative day 7 in patient two. Operative treatment was performed immediately on the same day without delay.

RESULTS

In both patients a combined transanal and transabdominal approach was performed. First step was a diagnostic laparoscopy in order to exclude fecal peritonitis. Using a single-port device (SILS Port Covidien), transanal inspection of the anastomosis was also performed: In both patients anastomotic tissue margins were vital, and the leakage affected only a quarter of the anastomotic circumference. Transanal stitches were placed to close the anastomotic leakage. Laparoscopic transabdominal irrigation was performed, and two suction drainages were placed in the pelvis. Postoperative antibiotic treatment and a gradual return to slid food were carried out. Functional result at follow-up of 102 and 112 days (with rectoscopy) showed no residual leak and no stricture of the anastomosis, and both of patients had a normal rectal function.

Monitoring needs and goal-directed fluid therapy within an enhanced recovery program

Patients having major abdominal surgery need perioperative fluid supplementation; however, enhanced recovery principles mitigate against many of the factors that traditionally led to relative hypovolemia in the perioperative period. An estimate of fluid requirements for abdominal surgery can be made but individualization of fluid prescription requires consideration of clinical signs and hemodynamic variables. The literature supports goal-directed fluid therapy. Application of this evidence to justify stroke volume optimization in the setting of major surgery within an enhanced recovery program is controversial. This article places the evidence in context, reviews controversies, and suggests implications for current practice and future research.

C-reactive protein is a predictive factor of anastomotic leakage after laparoscopic colorectal cancer surgery

AIM: To evaluate the potential predictive role of C-reactive protein (CRP) in assessing anastomotic leakage after laparoscopic colorectal cancer surgery.

METHODS: We reviewed pre- and postoperative serum CRP in 124 patients who underwent laparoscopic surgery for colorectal cancer between January 2013 and January 2014. Patients with anastomotic leakage (group A, n = 17) were compared to those without (group B, n = 107). Patients with ongoing infections before surgery or with acquired infections other than leakage were excluded. Mean pre- and postoperative values of CRP were compared.

RESULTS: The average values of serum CRP were significantly higher in group A than in group B starting from the 2nd postoperative day (POD) until the diagnosis of leakage (P < 0.001). The cut-off value of 80 mg/L on the 3rd POD maximized the sensitivity (77%) and specificity (98%) of serum CRP in assessing the risk of leakage.

CONCLUSION: According to these results, an early and persistent elevation of CRP after laparoscopic surgery for colorectal cancer is a marker of anastomotic leakage. A cut-off value > 80 mg/L on POD3 maximizes sensitivity and specificity.

Outpatient colectomy within an enhanced recovery program

INTRODUCTION

The application of a fast-track recovery program after surgery can decrease the physiological impact of surgery and reduce the duration of hospitalisation compared to conventional care. This program has permitted us to consider the performance of colectomy on an outpatient basis.

METHOD

After analyzing the recommendations for fast-track recovery, we developed and validated a specific protocol. Drawing on extensive experience in ambulatory surgery (inguinal hernia, cholecystectomy, adjustable gastric-banding), we formalized a protocol for outpatient colectomy. Patient selection criteria were the absence of serious or decompensated comorbidity, very good general condition, and full patient understanding of the procedure. Discharge was authorized if the patient met the exit criteria according to the Chung score. Postoperative surveillance was provided by regular home visits of a nurse trained in enhanced recovery, every afternoon until day 10.

RESULTS

Five patients underwent this management strategy (4 men and 1 woman, mean age 64 years, range: 59-69), for indications including cancer of the rectosigmoid junction (1 case), sigmoid diverticulitis (3 cases), and volvulus. The postoperative course was simple and uncomplicated except for two patients who had dysuria and an incisional hematoma, respectively.

CONCLUSION

To our knowledge, these are the first cases of colectomy performed strictly on an outpatient basis (i.e., stay<12h). We demonstrated the feasibility of outpatient colectomy when integrated into a protocol of enhanced recovery for selected patients provided that at-home monitoring was available.

Understanding how colorectal units achieve short length of stay: an interview survey among representative hospitals in England

BACKGROUND

Wide variation in the outcomes of colorectal surgery persists, despite a well-established evidence-base to inform clinical practice. This variation may be attributed to differences in quality of care, but we do not know what this means in practical terms of care delivery. This telephone interview study aimed to identify distinguishing characteristics in the organisation of care among colorectal units with the best length of stay results in England.

METHODS

Ten English National Health Service hospitals were identified with the shortest length of stay after elective colonic surgery between January 2011 and December 2012. Semi-structured telephone interviews were conducted with a senior colorectal surgeon and ward nurse, who were not informed of their performance, at each site. Audio recordings were professionally transcribed and thematically analysed for similarities and differences in practice between units.

RESULTS

All ten short length of stay units approached agreed to participate, and 19 of 20 interviews were recorded. These units standardised clinical care based upon an Enhanced Recovery Program. Beyond this, they organised the clinical team to efficiently and reliably deliver this package of care, with the majority of day-to-day care delivered by consultants and nurses. Patients were closely monitored for postoperative deterioration, using a combination of early warning scores, nurses' clinical judgement and regular senior medical review. Of note, operative volume and laparoscopy rates in these units were not statistically significantly different from the national average (p = 0.509 and p = 0.131, respectively). The postoperative analgesic strategy varied widely between units, from routine epidural use to local anaesthetic infiltration or patient-controlled analgesia.

CONCLUSIONS

The Enhanced Recovery Program may be seen as necessary but not sufficient to achieve the best length of stay results. In the study units, consultants and nurses led and delivered the majority of patient care on the ward. High quality teamwork helped detect and resolve clinical issues promptly, with nurses empowered to contact consultants directly if needed. Other units may learn from these teams by adopting protocol-based, consultant- or nurse-delivered care, and by improving coordination and communication between consultants and ward nurses.

Ostomy Closures in Children: Variations in Perioperative Care Do Not Change the Outcome

This study aimed to evaluate ostomy closure applications and outcomes and determine the effect of personal differences among surgeons on patient postoperative course. Ninety-eight patients who underwent elective ostomy (ileostomy and colostomy) closure for 8 years at a pediatric surgery training department were investigated. Postoperative complications included superficial surgical site infection (SSI; 9.4 %), organ/cavity infection (1 %), small bowel adhesions (8.2 %), and incisional hernia (1 %). SSI and postoperative complications were not affected by the preoperative antibiotic regimen used. Operation duration, pre- and postoperative antibiotic use durations, postoperative inpatient period, ostomy type, primary diagnosis, performance of abdominal exploration, SSI, and postoperative complications were not significantly different. However, the time of nasogastric (NG) tube withdrawal, time to oral feeding initiation, abdominal closure method used, and preoperative antibiotic regimen were significantly different among different surgeons. We conclude that while surgeons used different preoperative antibiotic regimens and abdominal closure methods and stipulated different times for NG tube withdrawal and oral feeding initiation, the postoperative course and prognosis were unaffected Thus, the pre- and postoperative inpatient period and antibiotic use duration can be decreased in children by procedure standardization using practice guidelines; the procedures can also be performed with a more aesthetic, acceptable incision.

Prevention of infectious complications after elective colorectal surgery in children: an American Pediatric Surgical Association Outcomes and Clinical Trials Committee comprehensive review

OBJECTIVE

This goal of this review was to examine the clinical evidence in support of commonly utilized measures intended to reduce complications following elective colorectal surgery.

DATA SOURCE

Literature searches were performed to identify relevant studies from Medline, PubMed, and Cochrane databases.

STUDY SELECTION

The American Pediatric Surgery Association Outcomes and Clinical Trials Committee selected eight questions to address this topic systematically in the context of three management areas: 1) appropriate utilization of systemic antibiotics for colorectal procedures, 2) reduction of stool burden through mechanical bowel preparation, and 3) intraluminal gut decontamination through use of enteral nonabsorbable antibiotics. Primary outcomes of interest included the occurrence of infectious and mechanical complications related to stool burden and intraluminal bacterial concentration (incisional surgical site infection, anastomotic leakage, and intraabdominal abscess).

RESULTS

The evidence in support of each management category was systematically reviewed, graded, and summarized in the context of the review's primary outcomes. Practice recommendations were made as deemed appropriate by the committee.

CONCLUSIONS

Clinical evidence in support of interventions to reduce infectious complications following colorectal surgery is derived almost exclusively from the adult literature. High-quality evidence to guide clinical practice in children is sorely needed, as the available data may have only limited relevance to pediatric colorectal diseases.

Variation of outcome and charges in operative management for diverticulitis

BACKGROUND

Outcomes after surgery for diverticulitis are of continued interest to improve quality of care. The aim of this study was to assess variations in mortality, length of stay, and patient charges between geographic regions of the United States.

METHODS

A retrospective analysis of the Nationwide Inpatient Sample database was performed. Adults with diverticulitis who underwent laparoscopic or open segmental colectomy were identified using ICD-9 codes. Subset analyses were performed by state and then compared. Outcomes included mortality, length of stay (LOS), and total charges. Results were adjusted for age, race, gender, findings of peritonitis, stoma placement, Charlson comorbidity index, and insurance status on multivariate analysis.

RESULTS

148,874 patients underwent segmental colectomy for diverticulitis from 1998 to 2010. Using California as the comparison state and after adjusting for covariates, in-hospital mortality was significantly higher in the State of New York (OR 1.32; 95 % CI 1.13-1.55; P < 0.05) and Mississippi (OR 2.84; 95 % CI 1.24-6.51, P < 0.02). Wisconsin had a significant lower mortality rate (OR 0.74; 95 % CI 0.59-0.94, P < 0.01). LOS was 1.4 days longer in New York and 0.54 days shorter in Wisconsin than in California (P < 0.01). Patients with age >40 years, findings of peritonitis, and without private insurance had higher in-hospital mortality and longer length of stay. Average hospital charges differed dramatically between the states in the observation period. The highest hospital charges occurred in California, Nebraska, and Nevada while lowest occurred in Maryland, Wisconsin and Utah.

CONCLUSIONS

Patients who undergo surgical treatment for diverticulitis in the United States have high geographic variation in mortality, LOS, and hospital charges despite adjusting for demographic and socioeconomic factors. Further analysis should be performed to identify the causes of outlier regions, with the goal of improving and standardizing best practices.

Introducing an enhanced recovery after surgery program in colorectal surgery: A single center experience

AIM: To study the implementation of an enhanced recovery after surgery (ERAS) program at a large University Hospital from “pilot study” to “standard of care”.

METHODS: The study was designed as a prospective single centre cohort study. A prospective evaluation of compliance to a protocol based on full application of all ERAS principles, through the progressive steps of its implementation, was performed. Results achieved in the initial pilot study conducted by a dedicated team (n = 47) were compared to those achieved in the shared protocol phase (n = 143) three years later. Outcomes were length of postoperative hospital stay, readmission rate, compliance to the protocol and morbidity. Primary endpoint was the description of the results and the identification of critical issues of large scale implementation of an ERAS program in colorectal surgery emerged in the experience of a single center. Secondary endpoint was the identification of interventions that have been proven to be effective for facilitating the transition from traditional care pathways to a multimodal management protocol according to ERAS principles in colorectal surgery at a single center.

RESULTS: During the initial pilot study (March 2009 to December 2010; 47 patients) conducted by a dedicated multidisciplinary team, compliance to the items of ERAS protocol was 93%, with a median length of hospital stay (LOS) of 3 d. Early anastomotic fistulas were observed in 2 cases (4.2%), which required reoperation (Clavien-Dindo grade IIIb). None of the patients had been discharged before the onset of the complication, which could therefore receive prompt treatment. There were also four (8.5%) minor complications (Clavien-Dindo grade II). Thirty days readmission rate was 4%. Perioperative mortality was nil. After implementation of the protocol throughout the Hospital in unselected patients (May 2012 to December 2012; 147 patients) compliance was 74%, with a median LOS of 6 d. Early anastomotic fistulas were observed in 11 cases (7.7%), 5 (3.5%) of which required reoperation (Clavien-Dindo grade IIIb). Two early anastomotic fistulas were treated by radiologic/endoscopic manoeuvres and 4 were treated conservatively. There were also 36 (25.2%) minor complications, 21 (14.7%) of which were Clavien-Dindo grade II and 15 (10.5%) of which were Clavien-Dindo grade I. Only two patients whose course was adversely affected by the development of an anastomotic leak had been discharged before the onset of the complication itself, requiring readmission. Readmission rate within 30 d was 4%. Perioperative mortality was 1%.

CONCLUSION: Our results confirm that introduction of an ERAS protocol for colorectal surgery allows quicker postoperative recovery and shortens the length of stay compared to historical series.

CT scan-based modelling of anastomotic leak risk after colorectal surgery

AIM

Prolonged ileus, low-grade fever and abdominal discomfort are common during the first week after colonic resection. Undiagnosed anastomotic leak carries a poor outcome and computed tomography (CT) scan is the best imaging tool for assessing postoperative abdominal complications. We used a CT scan-based model to quantify the risk of anastomotic leak after colorectal surgery.

METHOD

A case-control analysis of 74 patients who underwent clinico-radiological evaluation after colorectal surgery for suspicion of anastomotic leak was undertaken and a multivariable analysis of risk factors for leak was performed. A logistic regression model was used to identify determinant variables and construct a predictive score.

RESULTS

Out of 74 patients with a clinical suspicion of anastomotic leak, 17 (23%) had this complication confirmed following repeat laparotomy. In multivariate analysis, three variables were associated with anastomotic leak: (1) white blood cells count > 9 × 10(9) /l (OR = 14.8); (2) presence of ≥ 500 cm(3) of intra- abdominal fluid (OR = 13.4); and (3) pneumoperitoneum at the site of anastomosis (OR = 9.9). Each of these three parameters contributed one point to the risk score. The observed risk of leak was 0, 6, 31 and 100%, respectively, for patients with scores of 0, 1, 2 and 3. The area under the receiver operating characteristic curve for the score was 0.83 (0.72-0.94).

CONCLUSION

This CT scan-based model seems clinically promising for objective quantification of the risk of a leak after colorectal surgery.

Evolution and future of laparoscopic colorectal surgery

The advances of laparoscopic surgery since the early 1990s have caused one of the largest technical revolutions in medicine since the detection of antibiotics (1922, Flemming), the discovery of DNA structure (1953, Watson and Crick), and solid organ transplantation (1954, Murray). Perseverance through a rocky start and increased familiarity with the chop-stick surgery in conjunction with technical refinements has resulted in a rapid expansion of the indications for minimally invasive surgery. Procedure-related factors initially contributed to this success and included the improved postoperative recovery and cosmesis, fewer wound complications, lower risk for incisional hernias and for subsequent adhesion-related small bowel obstructions; the major breakthrough however came with favorable long-term outcomes data on oncological parameters. The future will have to determine the specific role of various technical approaches, define prognostic factors of success and true progress, and consider directing further innovation while potentially limiting approaches that do not add to patient outcomes.

Long-term changes in physical capacity after colorectal cancer treatment

Older patients with colorectal cancer are faced with the dilemma of choosing between the short-term risks of treatment and the long-term risks of insufficiently treated disease. In addition to treatment-related morbidity and mortality, patients may suffer from loss of physical capacity. The purpose of this review was to gather all available evidence regarding long-term changes in physical functioning and role functioning after colorectal cancer treatment, by performing a systematic Medline and Embase search. This search yielded 27 publications from 23 studies. In 16 studies addressing physical functioning after rectal cancer treatment, a median drop of 10% (range -26% to -5%) in the mean score for this item at three months. At six months, mean score was still 7% lower than baseline (range -18% to 0%) and at twelve months 5% lower (range -13% to +5%). For role functioning (i.e. ability to perform daily activities) after rectal cancer treatment, scores were -18% (range -39% to -2%), -8% (range -23% to +6%) and -5% (range -17% to +10%) respectively. Elderly patients experience the greatest and most persistent decline in self-care capacity (up to 61% at one year). This systematic review demonstrates that both physical functioning and role functioning are significantly affected by colorectal cancer surgery. Although initial losses are recovered partially during follow-up, there is a permanent loss in both aspects of physical capacity, in patients of all ages but especially in the elderly. This aspect should be included in patient counselling regarding surgery.

Robotic surgery for rectal cancer: Current immediate clinical and oncological outcomes

Laparoscopic rectal surgery continues to be a challenging operation associated to a steep learning curve. Robotic surgical systems have dramatically changed minimally invasive surgery. Three-dimensional, magnified and stable view, articulated instruments, and reduction of physiologic tremors leading to superior dexterity and ergonomics. Therefore, robotic platforms could potentially address limitations of laparoscopic rectal surgery. It was aimed at reviewing current literature on short-term clinical and oncological (pathological) outcomes after robotic rectal cancer surgery in comparison with laparoscopic surgery. A systematic review was performed for the period 2002 to 2014. A total of 1776 patients with rectal cancer underwent minimally invasive robotic treatment in 32 studies. After robotic and laparoscopic approach to oncologic rectal surgery, respectively, mean operating time varied from 192-385 min, and from 158-297 min; mean estimated blood loss was between 33 and 283 mL, and between 127 and 300 mL; mean length of stay varied from 4-10 d; and from 6-15 d. Conversion after robotic rectal surgery varied from 0% to 9.4%, and from 0 to 22% after laparoscopy. There was no difference between robotic (0%-41.3%) and laparoscopic (5.5%-29.3%) surgery regarding morbidity and anastomotic complications (respectively, 0%-13.5%, and 0%-11.1%). Regarding immediate oncologic outcomes, respectively among robotic and laparoscopic cases, positive circumferential margins varied from 0% to 7.5%, and from 0% to 8.8%; the mean number of retrieved lymph nodes was between 10 and 20, and between 11 and 21; and the mean distal resection margin was from 0.8 to 4.7 cm, and from 1.9 to 4.5 cm. Robotic rectal cancer surgery is being undertaken by experienced surgeons. However, the quality of the assembled evidence does not support definite conclusions about most studies variables. Robotic rectal cancer surgery is associated to increased costs and operating time. It also seems to be associated to reduced conversion rates. Other short-term outcomes are comparable to conventional laparoscopy techniques, if not better. Ultimately, pathological data evaluation suggests that oncologic safety may be preserved after robotic total mesorectal excision. However, further studies are required to evaluate oncologic safety and functional results.
