Laparoscopic ventral mesh rectopexy in the oldest old is safe: the race is run.

BACKGROUND: Laparoscopic ventral mesh rectopexy (LVMR) is considered to be the gold standard for managing rectal prolapse. Nevertheless, concerns have been expressed about the use of this procedure in elderly patients. The aim of the current study was to examine the perioperative safety of primary LVMR operations in the oldest old in comparison to younger individuals and to assess our hospital policy of offering LVMR to all patients, regardless of age and morbidity. METHODS: A retrospective study analysed demographic information, operation notes, meshes utilised, operation times, lengths of hospital stay (LOS) and American Society of Anesthesiologists (ASA) scores of patients who underwent LVMR at Elisabeth-TweeSteden Hospital between 2012 and 2023. RESULTS: Eighty-seven female patients underwent LVMR. Nineteen patients were 80 years of age or older (OLD group); the remaining 65 patients were under the age of 80 (YOUNG group). The difference between the groups in terms of age was statistically significant. ASA scores were not significantly different. No mortality was observed. There was no statistically significant difference between the groups in terms of LOS, operation time or morbidity. Moreover, the postoperative morbidity profile was excellent in both groups. CONCLUSION: LVMR seems to be a safe operation for the "oldest old" patients with comorbidity, despite a single-centre, retrospective trial with limited follow-up. The present study suggests abandoning the dogma that "frail patients with rectal prolapse are not suitable for laparoscopic ventral mesh rectopexy."

Reversal of left-sided colostomy utilizing single-port laparoscopy a multicenter European audit and overview of the literature.

BACKGROUND: Stoma reversal surgery can result in considerable morbidity and even mortality. Feasibility of utilizing single-port laparoscopy through the stoma fenestration have been shown before. Aim of the present observational study is to evaluate multicenter experiences of single-port reversal of left-sided colostomy (SPRLC) throughout Europe and to provide an overview of available literature on this topic. METHODS: All patients undergoing SPRLC in four different teaching hospitals throughout Europe are included. Primary outcome was 30-day postoperative complication rate. Secondary outcomes were postoperative length of stay (LOS), single-port success rate and conversion rates. Appraisal of the available literature in PubMed was performed. RESULTS: Of 156 SPRLC procedures, 98.7% of them were technically successful and 71.8% were without postoperative complications. No postoperative mortality was encountered. Superficial site infection occurred in 14.7%, anastomotic leakage in 3.9% and major complications in 8.3%. Median LOS was 4.0 days (1-69), single-port success rate was 64.7%, 12.8% and 21.2% (33/154) were converted to an open and multiport laparoscopic procedure, respectively. Literature shows equally favorable results in 131 patients divided over 5 cohorts with morbidity ranging from 0 to 30.4% and mortality from 0 to 2.2% and median LOS of 4-8 days. CONCLUSION: This study confirms the safety, feasibility and favorable results of the use of single-port approach in the reversal of left-sided colostomy in different centers in Europe with laparoscopic experienced colorectal surgeons. The available literature on this topic support and show equally favorable results using single-port laparoscopy for left-sided colostomy reversal surgery.

Hospital variation in sphincter-preservation rates in rectal cancer treatment: results of a population-based study in the Netherlands.

BACKGROUND: This study aimed to examine the sphincter-preservation rate variations in rectal cancer surgery. The influence of hospital volume on sphincter-preservation rates and short-term outcomes (anastomotic leakage (AL), positive circumferential resection margin (CRM), 30- and 90-day mortality rates) were also analysed. METHODS: Non-metastasized rectal cancer patients treated between 2009 and 2016 were selected from the Netherlands Cancer Registry. Surgical procedures were divided into sphincter-preserving surgery and an end colostomy group. Multivariable logistic regression models were generated to estimate the probability of undergoing sphincter-preserving surgery according to the hospital of surgery and tumour height (low, 5 cm or less, mid, more than 5 cm to 10 cm, and high, more than 10 cm). The influence of annual hospital volume (less than 20, 20-39, more than 40 resections) on sphincter-preservation rate and short-term outcomes was also examined. RESULTS: A total of 20 959 patients were included (11 611 sphincter preservation and 8079 end colostomy) and the observed median sphincter-preservation rate in low, mid and high rectal cancer was 29.3, 75.6 and 87.9 per cent respectively. After case-mix adjustment, hospital of surgery was a significant factor for patients' likelihood for sphincter preservation in all three subgroups (P < 0.001). In mid rectal cancer, borderline higher rates of sphincter preservation were associated with low-volume hospitals (odds ratio 1.20, 95 per cent c.i. 1.01 to 1.43). No significant association between annual hospital volume and sphincter-preservation rate in low and high rectal cancer nor short-term outcomes (AL, positive CRM rate and 30- and 90-day mortality rates) was identified. CONCLUSION: This population-based study showed a significant hospital variation in sphincter-preservation rates in rectal surgery. The annual hospital volume, however, was not associated with sphincter-preservation rates in low, and high rectal cancer nor with other short-term outcomes.

Management of cryptoglandular fistula-in-ano among gastrointestinal surgeons in the Netherlands.

BACKGROUND: Management of cryptoglandular fistula-in-ano (FIA) can be challenging. Despite Dutch and international guidelines determining optimal therapy is still quite difficult. The aim of this study was to report current practices in the management of cryptoglandular FIA among gastrointestinal surgeons in the Netherlands. METHODS: Dutch surgeons and residents who are treating FIA regularly were sent a survey invitation by email. The survey was available online from September 19 to December 1 2019. The questionnaire consisted of 28 questions concerning diagnostic and surgical techniques in the treatment of intersphincteric and transsphincteric FIA. RESULTS: In total, 147 (43%) surgeons responded and completed the survey. Magnetic resonance imaging was the preferred diagnostic imaging modality (97%) followed by the endo-anal ultrasound (12%). In case of a high FIA, 86% used a non-cutting seton. Most respondents removed a seton between 6 weeks and 3 months (n = 84, 58%). Fistulotomy was the procedure of preference in low transsphincteric (86%) and low intersphincteric FIA (92%). Mucosal advancement flap (MAF) and ligation of intersphincteric fistula tract (LIFT), with 78% and 46%, respectively, were the procedures that were applied most often in high transsphincteric FIA. In high intersphincteric FIA 67% performed a MAF and 33% a fistulotomy. Thirty-three percent of all respondents stated that they habitually closed the internal fistula opening, half of them used a Z-plasty. For debridement of the fistula tract the preferred method was curettage (78%). CONCLUSIONS: Dutch gastrointestinal surgeons use various techniques in the management of FIA. Novel promising techniques should be investigated adequately in sufficient large trials to increase consensus. A core outcome measurement and a prospective international database would help in comparing results. Until then, treatment should be adjusted to the individual patient, governed by fistula characteristics and patient choice.

Laparoscopic transdiaphragmatic pericardial fenestration in palliative care: how I do it.

BACKGROUND: The optimal therapeutic strategy for drainage of malignant pericardial effusion is not yet determined. Several techniques are described, with different benefits and disadvantages. The literature suggests that surgical drainage of pericardial effusions has less effusion recurrence; however, randomized controlled trials are not available. Due to the nature of the disease, quality of life should always be considered while making treatment decisions. METHODS: A retrospective analysis of all consecutive patients from November 2016 until June 2019 of our institution in the Netherlands was performed. All patients underwent laparoscopic pericardial fenestration after echocardiography and request for operative treatment by the cardiologist. The same operation technique was performed in every case. RESULTS: Four out of five of our patients needed pericardial fenestration because of oncological diseases. No hemodynamically instability was noted during this fast technique, achieving direct relief of symptoms. No treatment-related morbidity or mortality, nor the need for re-intervention was encountered. We compared the outcome of our five patients with the existing evidence in the literature. CONCLUSIONS: In this article, we highlight the laparoscopic transdiaphragmatic pericardial fenestration as a treatment of preference in a non-acute palliative setting. This laparoscopic approach is safe, and can be a valuable alternative among the other well-known approaches.

The complexity of cryptoglandular fistula-in-ano can be predicted by the distance of the external opening to the anal verge; implications for preoperative imaging?

BACKGROUND: Many surgeons believe that the distance from the external opening to the anal verge (DEOAV) predicts the complexity of a cryptoglandular fistulas-in-ano and, therefore, predicts the need for additional imaging. However, there is no evidence to support this. The primary aim of this study was to determine if DEOAV can predict the complexity of a fistula. Secondary aims were clinical outcome and identification of those patients that might not benefit from preoperative imaging. METHODS: All patients having surgery for cryptoglandular fistula-in-ano between January 2014 and December 2016 were evaluated. Preoperative imaging was used to classify fistulas as simple or complex. The DEAOV was measured preoperatively and was divided into categories ≤ 1 cm, 1-2 cm, or > 2 cm. The relationship between the DEOAV and complexity of the fistula was investigated. Clinical outcome was recorded and a group of patients that might not benefit from preoperative imaging was identified. RESULTS: A total of 103 patients [m:f = 65:38, median age 47 (range 19-79) years] were included. Magnetic resonance imaging identified 39 simple and 64 complex fistulas. The percentage of simple fistula was 88% in fistulas with DEAOV ≤ 1 cm, 48% in DEAOV 1-2 cm and 38% in > 2 cm. There was a significant difference between the complexity of the fistula and the distance to the anal verge (p < 0.001). The overall healing rate was 88%. CONCLUSIONS: The complexity of perianal fistula depends on the DEAOV. We propose that preoperative imaging should be performed in fistulas with external opening > 1 cm from the anal verge.

Loss of seton in patients with complex anal fistula: a retrospective comparison of conventional knotted loose seton and knot-free seton.

BACKGROUND: Loose setons are often utilized. Replacements after seton loss are frequent, but the exact incidence of this loss of seton (LOS) in patients is unknown. The aim of the present study was to assess the incidence of LOS in a population with complex anal fistula, comparing the knot-free loose seton with the conventional knotted loose seton. METHODS: All consecutive patients treated with a loose seton for complex anal fistula in two large teaching hospitals in the Netherlands between January 2017 and December 2019 were included in the present study. The incidence of loss of a conventional knotted loose seton was compared with the loss of commercially available knot-free setons. RESULTS: There were 212 patients. Fifty-two patients were included in the knotted loose group and 160 patients were included in the knot-free seton group. Sixteen patients who were treated with both a knotted and a knot-free loose seton were included in both groups. The incidence of LOS was 12% in the knotted seton group and 28% in the knot-free loose seton group (p = 0.02). Median time to LOS was 36 days for the knotted loose seton and 89 days for the knot-free loose seton (p = 0.36). Sex (p = 0.61), age at the time of seton placement (p = 0.60), and presence of inflammatory bowel disease (p = 0.28) were not significantly associated with LOS. CONCLUSIONS: LOS occurs frequently in patients treated for complex anal fistulas. The incidence of LOS is significantly higher in patients treated with a knot-free loose seton. Further developments in seton manufacturing should be focussed on optimisation of the closure mechanism.

Implementation of an easy in-hospital educational stoma pathway results in decrease of home nursing care services after discharge.

AIM: New stoma patients often rely heavily on the assistance of the ward nursing staff during the hospital stay and on the availability of home nursing care services (HNCS) after discharge. An easily executable 4-day in-hospital educational stoma pathway was developed and implemented. The aim was to increase their level of independence (LOI) in order to reduce the need for HNCS after discharge. METHOD: All new stoma patients on the gastrointestinal surgery ward, physically and psychologically capable of performing independent stoma care (SC), were enrolled in this pathway. They were compared to a retrospective control group of new stoma patients before the onset of the stoma pathway. The primary outcome is the need and frequency of HNCS for SC at the moment of discharge. Secondary outcome is the LOI in SC at discharge. RESULTS: A total of 145 patients [m:f = 102:43, median age 67 (range 27-90) years] were included in the present study. Patients requiring daily HNCS for SC decreased from 80% to 50%, P < 0.001; patients discharged without HNCS for SC increased from 5% to 27%. Patients' independence in SC at discharge increased from 8% to 68%, P < 0.001. CONCLUSION: This study shows that a clinical 4-day in-hospital educational stoma pathway is feasible and effective in increasing the LOI in SC of new stoma patients and significantly reducing their need for HNCS. Cost-benefit analysis and applicability of this pathway in multicentre settings are currently being investigated.

MRI response rate after short-course radiotherapy on rectal cancer in the elderly comorbid patient: results from a retrospective cohort study.

BACKGROUND: The aim of the present study was to evaluate MRI response rate and clinical outcome of short-course radiotherapy (SCRT) on rectal cancer as an alternative to chemoradiotherapy in patients where downstaging is indicated. METHODS: A retrospective analysis was performed of a patient cohort with rectal carcinoma (cT1-4cN0-2 cM0-1) from a large teaching hospital receiving restaging MRI, deferred surgery or no surgery after SCRT between 2011 and 2017. Patients who received chemotherapy during the interval between SCRT and restaging MRI were excluded. The primary outcome measure was the magnetic resonance tumor regression grade (mrTRG) at restaging MRI after SCRT followed by a long interval. Secondary, pathological tumor stage, complete resection rate and 1-year overall survival were assessed. RESULTS: A total of 47 patients (M:F = 27:20, median age 80 (range 53-88) years), were included. In 33 patients MRI was performed for response assessment 10 weeks after SCRT. A moderate or good response (mrTRG≤3) was observed in 24 of 33 patients (73%). While most patients (85%; n = 28) showed cT3 or cT4 stage on baseline MRI, a ypT3 or ypT4 stage was found in only 20 patients (61%) after SCRT (p <  0.01). A complete radiologic response (mrTRG 1) was seen in 4 patients (12%). Clinical N+ stage was diagnosed in n = 23 (70%) before SCRT compared to n = 8 (30%) post-treatment (p = 0.03). After SCRT, 39 patients underwent deferred surgery (after a median of 14 weeks after start of SCRT) and a resection with complete margins was achieved in 35 (90%) patients. One-year overall survival after surgery was 82%. Complete pathological response was found in 2 patients (5%). CONCLUSIONS: The use of SCRT followed by a long interval to restaging showed a moderate to good response in 73% and therefore can be considered as an alternative to chemoradiotherapy in elderly comorbid patients.

Hospital variance in neoadjuvant rectal cancer treatment and the influence of a national guideline update: Results of a nationwide population-based study.

INTRODUCTION: The aim of this study was to examine the hospital variation in neoadjuvant treatment of rectal cancer according to the different risk groups (low-, intermediate- and high-risk) and evaluate the influence on survival. MATERIALS AND METHODS: Patients with non-metastasized rectal cancer diagnosed between 2009 and 2016 were selected from the Netherlands Cancer Registry. The observed and case-mix adjusted distribution of the different neoadjuvant treatment schemes (none, radiotherapy (RT), chemoradiotherapy (CRT)) by hospital of diagnosis were generated for each risk group in the cohorts before and after the national guideline update of 2014. RESULTS: A total of 25,306 patients were included and after case-mix adjustment, hospital of diagnosis was found to have a significant impact on neoadjuvant treatment administration in each of the three risk groups (p < 0.001). Overall survival was however not influenced, except for the high-risk group where hospitals with highest rates of CRT were associated with a better 5-years overall survival (HR 0.79; p = 0.03). After guideline revision, the rate of patients in the low-risk group who did not undergo RT increased from a median of 30.8% to 90.5% (p < 0.001). CONCLUSION: Although a significant change in treatment was observed after revision of the national guidelines, a wide range of hospital variation still exists in administered neoadjuvant treatment in rectal cancer patients. High-risk rectal cancer patients had a better survival when treated in hospitals with the highest rates of CRT provided. In order to minimize treatment differences, further research into the causes of this variation and implementation of regionalized MDTs may be warranted.

Outcomes of completion total mesorectal excision are not compromised by prior transanal minimally invasive surgery.

AIM: Transanal minimally invasive surgery (TAMIS) is used increasingly often as an organ-preserving treatment for early rectal cancer. If final pathology reveals unfavourable histological prognostic features, completion total mesorectal excision (cTME) is recommended. This study is the first to investigate the results of cTME after TAMIS. METHOD: Data were retrieved from the prospective database of the Elisabeth-TweeSteden Hospital. Completion TME patients were case matched with a control group of patients undergoing primary TME (pTME). Primary and secondary outcomes were surgical outcomes and oncological outcomes, respectively. RESULTS: From 2011 to 2017, 20 patients underwent cTME and were compared with 40 patients undergoing pTME. There were no significant differences in operating time (238 min vs 226 min, P = 0.53), blood loss (137 ml vs. 158 ml, P = 0.88) or complications (45% vs 55%, P = 0.07) between both groups. There was no 90-day mortality in the cTME group. The mesorectal fascia was incomplete in three patients (15%) in the cTME group compared with no breaches in the pTME group (P = 0.083). There were no local recurrences in either group. In three patients (15%), distant metastases were detected after cTME compared with one patient (2.5%) in the pTME group (P = 0.069). After cTME patients had a 1- and 5-year disease-free survival of 85% compared with 97.5% for the pTME group (P = 0.062). CONCLUSION: Completion TME surgery after TAMIS is not associated with increased peri- or postoperative morbidity or mortality compared with pTME surgery. After cTME surgery patients have a similar disease-free and overall survival when compared with patients undergoing pTME.

Training in colorectal surgery in Europe and 20 years of the European Board of Surgical Qualification coloproctology examination.

AIM: Training in colorectal surgery across Europe is not yet standardized. The European Board of Surgical Qualification (EBSQ) coloproctology examination has been held annually since 1998. The aims of this study were to illustrate the current situation of coloproctology specialization in Europe and to analyse the EBSQ examinations held over the last 20 years. METHOD: A survey, focused on current training and education in colorectal surgery in Europe, was conducted among all national representatives of the European Society of Coloproctology (ESCP) in 2018. Candidate demographics (1998-2018) and the results of the EBSQ examination (2007-2018) were analysed. RESULTS: In Europe, there are currently 26 national colorectal societies, 27 national annual colorectal meetings, 16 national specialized training programmes and 13 national colorectal fellowships. Six countries have board certification in colorectal surgery and five a dedicated examination. During the last 20 years, 475 candidates from 29 countries, of whom 88 (19%) were women, passed the EBSQ examination. The pass rate was higher in younger applicants (< 42 years, P = 0.01). The success rate was higher for candidates with academic experience (more than five publications or presentations) and with an academic title (thesis) (P = 0.01). CONCLUSION: Colorectal surgical training is still not standardized in Europe, although efforts have been made to recognize colorectal surgery as an independent speciality. The number of holders of the EBSQ Diploma has increased over the years, demonstrating the acceptance of the examination among European surgeons. Young candidates with an academic profile are the most successful.

Implementation of the small bites closure of abdominal midline incisions in clinical practice is correlated with a reduction in surgical site infections.

BACKGROUND: Small steps wound closure of midline laparotomy has been reported to decrease the incidence of incisional hernia development in two randomized controlled trials. The aim of the present study was to evaluate the effect of implementing the small steps wound closure technique in clinical practice with regards to the development of incisional ventral hernia (IVH) and surgical site infections (SSI) in clinical practice. METHODS: Implementation of the small steps wound closure technique using the small tissue bites technique as the standard closure technique for abdominal midline incisions in our clinical practice was done in March 2015. For this study, all patients from June 2013 until June 2016 with a midline laparotomy, either long or small in case of specimen extraction in laparoscopic surgery, in either elective or emergency setting were included. Conventional large bite wound closure was compared to small steps wound closure with regards to the development of SSI, IVH as well as burst abdomen. RESULTS: A total of 327 patients were included. The small steps suture technique was used in 136 (42%) of the patients, whereas the conventional large bites suture technique was used in 191 patients (58%). A total of 54 patients in the large bites group developed SSI (28%) compared to 23 (17%) patients in the small steps group (p = 0.02). A total number of 10 patients (7%) developed IVH in the small steps group compared to 27 patients (14%) in the large bites group (p = 0.08). CONCLUSION: Implementation of small bites wound closure of abdominal midline incisions in clinical practice was correlated with a reduction in surgical site infections.

Implementation of laser ablation of fistula tract (LAFT) for perianal fistulas: do the results warrant continued application of this technique?

BACKGROUND: Laser Ablation of Fistula Tract (LAFT) is a novel technique for the treatment of perianal fistulas. Initial reports have shown moderate-to-good results. The aim of this study was to evaluate this implementation and the effectiveness of this technique. Patients were offered LAFT as a treatment option for their perianal fistulas at the outpatient clinic between November 2016 and April 2018. Inclusion criteria were intersphincteric and transsphincteric fistula of cryptoglandular origin [10]. Exclusion criteria were supra- or extrasphincteric fistula, Crohn's disease, presence of undrained collections or side tracts and malignancy-related fistula. The primary outcome was fistula healing rate, the main secondary outcome incidence of postoperative fecal incontinence. Healing and postoperative FISI were evaluated at our outpatient clinic during follow-up at 6 and 12 weeks. A questionnaire was sent to all patients to evaluate the long-term postoperative FISI and patient satisfaction after 3 months. RESULTS: Between November 2016 and April 2018, 20 patients [m:f = 4:16, median age 45 (27-78) years] underwent LAFT. Median follow-up was 10 months (IQR 7.3 months). A draining seton was placed in 15 (75%) of all patients with a median time of 12 weeks (IQR 14 weeks) prior to LAFT. Five intersphincteric and 13 transsphincteric fistulas were treated. Overall healing rate was 20% (4/20). The median postoperative fecal incontinence severity index (FISI) score was 0 (range 0-38); however, we found a change in continence in 39% of the patients. CONCLUSIONS: LAFT has now been discontinued as a treatment of cryptoglandular perianal fistulas in our centre, because of its disappointing results. Further detailed research seems to be warranted to investigate its exact indication and limitations.

Postoperative mortality in elderly patients with colorectal cancer: The impact of age, time-trends and competing risks of dying.

BACKGROUND: Worse prognosis in elderly colorectal cancer (CRC) patients may be cancer or treatment related, or death from other causes. This population-based study aimed to compare survival among non-metastatic CRC patients between age groups and notice time trends in mortality rates. METHODS: Primary stage I-III CRC patients who underwent resection between 2008 and 2013 were selected from the Netherlands Cancer Registry. Patients were divided into three equally distributed age groups and a separated group including the oldest old (<65, 65-74, 75-84 and ≥ 85 years). Survival rates were calculated by age groups and tumour localization. Relative excess risks of death, 30-day, 1-year mortality and 1-year excess mortality were calculated. RESULTS: 52296 patients were included. Age-related differences in 5-year overall survival were observed (colon cancer: 82%, 73%, 56% and 35%; rectal cancer: 82%, 74%, 56% and 38%; p < 0.0001). Age-related differences were less prominent in relative survival and disappeared in conditional relative survival (condition of surviving 1 year). Thirty-day mortality rates decreased over time (colon cancer: 4.9%-3.4%; rectal cancer: 3.0%-1.7%); 1-year mortality rates decreased from 11.9% to 9.6% in colon cancer and from 8.0% to 6.4% in rectal cancer. One-year excess mortality increased with age (17.3% and 12.9% in patients with colon or rectal cancer aged ≥85 years). CONCLUSION: One-year mortality rates remain high in elderly patients. Age-related differences in survival disappeared after adjustment for expected death from other causes and first-year mortality. Beneficial time trends in 1-year mortality rates underline that survival in elderly after CRC surgery is modifiable.
