Influence of Conversion and Anastomotic Leakage on Survival in Rectal Cancer Surgery; Retrospective Cross-sectional Study

Background Conversion and anastomotic leakage in colorectal cancer surgery have been suggested to have a negative impact on long-term oncologic outcomes. The aim of this study in a large Dutch national cohort was to analyze the influence of conversion and anastomotic leakage on long-term oncologic outcome in rectal cancer surgery. Methods Patients were selected from a retrospective cross-sectional snapshot study. Patients with a benign lesion, distant metastasis, or unknown tumor or metastasis status were excluded. Overall (OS) and disease-free survival (DFS) were compared between laparoscopic, converted, and open surgery as well as between patients with and without anastomotic leakage. Results Out of a database of 2095 patients, 638 patients were eligible for inclusion in the laparoscopic, 752 in the open, and 107 in the conversion group. A total of 746 patients met the inclusion criteria and underwent low anterior resection with primary anastomosis, including 106 (14.2%) with anastomotic leakage. OS and DFS were significantly shorter in the conversion compared to the laparoscopic group (p = 0.025 and p = 0.001, respectively) as well as in anastomotic leakage compared to patients without anastomotic leakage (p = 0.002 and p = 0.024, respectively). In multivariable analysis, anastomotic leakage was an independent predictor of OS (hazard ratio 2.167, 95% confidence interval 1.322-3.551) and DFS (1.592, 1077-2.353). Conversion was an independent predictor of DFS (1.525, 1.071-2.172), but not of OS. Conclusion Technical difficulties during laparoscopic rectal cancer surgery, as reflected by conversion, as well as anastomotic leakage have a negative prognostic impact, underlining the need to improve both aspects in rectal cancer surgery

Long-term Oncologic Outcome After Laparoscopic Converted or Primary Open Resection for Colorectal Cancer:A Systematic Review of the Literature

Purpose: The aim of this study was to critically review the current evidence regarding the oncologic outcomes after laparoscopic converted or open resection for colorectal cancer. Materials and Methods: A literature search was performed in Pubmed. Study selection and data acquisition were independently performed by 2 reviewers. Results: The search strategy yielded a total of 746 articles, resulting in 7 studies eligible for inclusion. A total of 9190 (57 to 8307) patients were included in the open and 238 (17 to 56) in the converted group. In none of the studies, differences were found in disease stage between both groups. There were no significant differences between both groups with regard to overall survival, local recurrence and distant metastasis rate. Conclusions: There is currently insufficient evidence that patients who had a laparoscopic resection for colorectal cancer converted to open surgery have a worse oncologic outcome than patients who were primarily treated by an open approach

Anastomotic Height is a Valuable Indicator of Long-term Bowel Function Following Surgery for Rectal Cancer

BACKGROUND: The exact relation between anastomotic height after rectal cancer surgery and postoperative bowel function problems has not been investigated in the long term, causing ineffective treatment.OBJECTIVE: To determine the effect of anastomotic height on long-term bowel function and generic quality of life.DESIGN: A multicenter cross-sectional study.SETTINGS: Seven Dutch hospitals in the north of the Netherlands participated.PATIENTS: All patients who underwent rectal cancer surgery between 2009 and 2015 in the participating hospitals received the validated Defecation and Fecal Continence and Short-Form 36 questionnaires. Deceased patients, patients with a permanent stoma or an anastomosis &gt;15 cm from the anal verge, intellectual disability, or living abroad were excluded.MAIN OUTCOME MEASURES: Primary outcomes were constipation (Rome IV), fecal incontinence (Rome IV), and major low anterior resection syndrome. Secondary outcomes were the generic quality of life scores.RESULTS: The study population (N=630) had a median follow-up of 58.0 months. In multivariable analysis, constipation (OR = 1.08, 95% CI, 1.02-1.15, p = 0.011), fecal incontinence (OR = 0.91, 95% CI, 0.84-0.97, p = 0.006), and major low anterior resection syndrome (OR = 0.93, 95% CI, 0.87-0.99, p = 0.027), were significantly associated with anastomotic height. The curves illustrating the probability of constipation and fecal incontinence crossed at an anastomotic height of 7 cm, with 95% CIs overlapping between 4.5-9.5 cm. There was no relation between quality of life scores and anastomotic height.LIMITATIONS: The study is limited by its cross-sectional design.CONCLUSIONS: This study might serve as a guide for the clinician to effectively screen and treat fecal incontinence and constipation during the follow-up of patients after rectal cancer surgery. More attention should be paid to fecal incontinence in patients with an anastomosis below 4.5 cm and towards constipation in patients with an anastomosis above 9.5 cm.

Five-Year Subjective and Objective Results of Laparoscopic and Conventional Nissen Fundoplication: A Randomized Trial

OBJECTIVE: The purpose of this prospective study was to compare the subjective and objective outcome of laparoscopic (LNF) and conventional Nissen fundoplication (CNF) up to 5 years after surgery as obtained in a multicenter randomized controlled trial. SUMMARY OF BACKGROUND DATA: LNF is regarded as surgical treatment of first choice for refractory gastroesophageal reflux disease by many surgeons based on several short- and mid-term studies. The long-term efficacy of Nissen fundoplication, however, is still questioned as objective data gathered from prospective studies are lacking. METHODS: From 1997 to 1999, 177 patients were randomized to undergo LNF or CNF. Five years after surgery, all patients were requested to fill in questionnaires and to undergo esophageal manometry and 24-hour pH-metry. RESULTS: A total of 148 patients agreed to participate in the follow-up study: 79 patients after LNF and 69 after CNF. Of these, 97 patients (48 LNF, 49 CNF) consented to undergo esophageal manometry and 24-hour pH-metry. At 5 years follow-up, 20 patients had undergone reoperation: 12 after LNF (15%) and 8 after CNF (12%). There was no difference in subjective outcome, with overall satisfaction rates of 88% and 90%, respectively. Total esophageal acid exposure times (pH < 4) were 2.1% ± 0.5% and 2.0% ± 0.6%, respectively (P = 0.21). Antisecretory medication was taken daily in 14% and 16%, respectively (P = 0.29). There was no correlation between medication use and acid exposure and indices of symptom-reflux association (symptom index and symptom association probability). No significant differences between subjective and objective results at 3 to 6 months and results obtained at 5 years after surgery were found. CONCLUSIONS: The effects of LNF and CNF on general state of health and objective reflux control are sustained up to 5 years after surgery and the long-term results of LNF and CNF are comparable. A substantial minority of patients in both groups had a second antireflux operation or took antisecretory drugs, although the use of those medications did not appear to be related to abnormal esophageal acid exposure

Life with a stoma across five European countries-a cross-sectional study on long-term rectal cancer survivors

Purpose Stoma-related problems are known to be important to patients and potentially affect everyday life. The prevalence of stoma-related problems in rectal cancer survivors remains undetermined. This study aimed to examine aspects of life with a long-term stoma, stoma management, and stoma-related problems and explore the impact of stoma-related problems on daily life. Methods In total, 2262 patients from 5 European countries completed a multidimensional survey. Stoma-related problems were assessed using the Colostomy Impact score. Multivariable regression analysis, after adjusting for potential confounding factors, provided odds ratio (OR) and 95% confidence intervals (CI) for stoma-related problems' association with restrictions in daily life. Results The 2262 rectal cancer survivors completed the questionnaire at a median of 5.4 years (interquartile range 3.8-7.6) after stoma formation. In the total sample, leakage (58%) and troublesome odour (55%) were most prevalent followed by skin problems (27%) and pain (21%). Stoma-related problems were more prevalent in patients with parastomal bulging. A total of 431 (19%) reported feeling restricted in daily activities in life with a stoma. Leakage, odour, skin problems, stool consistency, and frequent appliance changes were significantly associated with restrictions in daily life. The highest risk of experiencing restrictions was seen for patients having odour (OR 2.74 [95% CI: 1.99-3.78]) more than once a week and skin problems (OR 1.77 [95% CI: 1.38-2.27]). Conclusion In this large cohort with rectal cancer, stoma-related problems were highly prevalent and impacted daily life. Supportive care strategies should entail outreach to patients with a long-term stoma

EAES recommendations for the management of gastroesophageal reflux disease

BACKGROUND: Gastroesophageal reflux disease (GERD) is one of the most frequent benign disorders of the upper gastrointestinal tract. Management of GERD has always been controversial since modern medical therapy is very effective, but laparoscopic fundoplication is one of the few procedures that were quickly adapted to the minimal access technique. The purpose of this project was to analyze the current knowledge on GERD in regard to its pathophysiology, diagnostic assessment, medical therapy, and surgical therapy, and special circumstances such as GERD in children, Barrett's esophagus, and enteroesophageal and duodenogastroesophageal reflux. METHODS: The European Association of Endoscopic Surgery (EAES) has tasked a group of experts, based on their clinical and scientific expertise in the field of GERD, to establish current guidelines in a consensus development conference. The expert panel was constituted in May 2012 and met in September 2012 and January 2013, followed by a Delphi process. Critical appraisal of the literature was accomplished. All articles were reviewed and classified according to the hierarchy of level of evidence and summarized in statements and recommendations, which were presented to the scientific community during the EAES yearly conference in a plenary session in Vienna 2013. A second Delphi process followed discussion in the plenary session. RESULTS: Recommendations for pathophysiologic and epidemiologic considerations, symptom evaluation, diagnostic workup, medical therapy, and surgical therapy are presented. Diagnostic evaluation and adequate selection of patients are the most important features for success of the current management of GERD. Laparoscopic fundoplication is the most important therapeutic technique for the success of surgical therapy of GERD. CONCLUSIONS: Since the background of GERD is multifactorial, the management of this disease requires a complex approach in diagnostic workup as well as for medical and surgical treatment. Laparoscopic fundoplication in well-selected patients is a successful therapeutic option
