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."

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.

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.

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.

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.

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.

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.

The effect of proctoring on the learning curve of transanal minimally invasive surgery for local excision of rectal neoplasms

BACKGROUND

The current method of choice for local resection of benign and selected malignant rectal tumors is transanal endoscopic microsurgery. Transanal minimally invasive surgery (TAMIS) yields similar oncological results and better patient reported outcomes when compared to transanal endoscopic micro surgery. However, due to the technical complexity of TAMIS, a significant learning curve has been suggested. Data on the surgical learning curve are limited. The aim of our study was to investigate surgeon specific learning curves for TAMIS procedures for the local excision of selected rectal tumors, and analyze the effects of proctoring on operating time and outcome.

METHODS

The current study was prospective of all TAMIS procedures performed by two surgeons from October 2010 to November 2017. Margin positivity, specimen fragmentation, adverse events and operative time were evaluated with a cumulative sum analysis to determine the number of procedures required to reach proficiency. Cumulative sum (CUSUM) analysis was used to determine trends in changes over time.

RESULTS

The earliest adopter, surgeon A, performed 103 procedures, was not proctored and developed the standardized institutional program. Surgeon B, performed 26 cases, had the benefit of a proctorship and availability of a standardized program. The CUSUM curve for operative time showed a change after 36 cases for surgeon A and after 10 cases for surgeon B. For margin positivity proficiency was reached after 31 and 6 cases for surgeon A and B, respectively. The complications curve for surgeon A showed a three-phase learning curve with a decrease after the 26th case whereas surgeon B only had one (3.8%) complication in the learning phase with no change point in the CUSUM curve. Comparing pre- and post-proficiency periods there was a decrease in operating time for both surgeon A (84.4 ± 47.3 to 55.9 ± 30.1 min) and surgeon B (90.6 ± 64.to 53 ± 26.5 min; p < 0.001). Overall margin positivity rates decreased non significantly from 21.7 to 4.8% (p = 0.23). Complications were higher in the pre-proficiency period (21.7% vs. 13.0%; p = 0.02). Surgeon A had significantly more postoperative complications in pre-proficiency phase when compared to surgeon B (25% vs. none, p < 0.001), in the post-proficiency phase there was no statistically significant difference between both surgeons (p = 0.08).

CONCLUSIONS

Our results suggest that to reach satisfactory results for TAMIS, 18-31 procedures are required. Standardized institutional operative protocols together with proficient proctorship may contribute to a shorter learning curve with fewer cases (6-10) required to reach proficiency.

[Assessment of day surgery in a district training hospital: safety, efficacy and patient's satisfaction]

OBJECTIVE

To assess the quality of day surgery in the St. Antonius Hospital in Nieuwegein, the Netherlands.

DESIGN

Prospective and descriptive.

METHODS

During one year all patients treated by general surgeons in ambulatory surgery of the St. Antonius Hospital, Nieuwegein, the Netherlands (breast surgery (n = 232), hernia repair (n = 143), varicose vein surgery (n = 137), lymph node or lump excision (n = 85), (peri-)anal surgery (n = 70), ganglion surgery (n = 41), removal of bone implants (n = 41), laparoscopic cholecystectomy (n = 23), miscellaneous (n = 82); total 854) were evaluated by telephone questionnaires six weeks after surgery, to measure the following three aspects of quality of care: safety, efficacy and patient's satisfaction. Questions were asked about complications, visits to the emergency room, the outpatient clinic and the general practitioner and extra care at home. Unplanned clinical admissions following day surgery and re-admissions were registered. All outpatient clinic charts were also checked for complications. Whenever the registration of complications was incomplete the patient's general practitioner was contacted. All patients gave informed consent.

RESULTS

After 854 planned day cases 823 patients (96.4%) returned home the same day. Reasons for clinical admission following day surgery were pain and/or nausea (n = 8), an operation late in the afternoon (n = 7), haemorrhage (n = 6), more extensive surgery than expected (n = 3), others (n = 7). Of all patients who returned home the same day and about whom the interview yielded adequate information (n = 656; 80%) 54 (7%) suffered from a complication (wound infection (n = 28), haemorrhage (n = 7), haematoma (n = 5), seroma (n = 3), phlebitis (n = 2), infection skin (n = 2), wound dehiscence (n = 2), others (n = 5)). Six patients were re-admitted. In the hospital and outpatient clinic 40 patients were seen without an appointment (6%) and 91 patients visited their general practitioner (14%). After surgery 84 (13%) patients were helped at home by friends or family. Of the group of patients who were successfully treated in day care 14% would have preferred an overnight stay.

[Increase of surgical day treatment in the Netherlands]

OBJECTIVE

To assess the quantitative development of day surgery in the Netherlands.

DESIGN

Descriptive.

SETTING

St. Antonius Hospital, Nieuwegein, the Netherlands.

METHOD

Numbers of admissions in the period 1984-1995 were obtained from Dutch data bases of the National Hospital Institution (NZi). From SIG Health Care Information numbers were obtained with regard to seven specified interventions in the years 1991 to 1995, i.e. breast tumour excision, inguinal hernia repair, varicose vein operation, laparoscopic sterilisation, knee arthroscopy, cataract operation and tonsillectomy. The increase if any of the number of interventions in day care was determined by placing the hospitals in the order of decreasing proportions of day care, and subsequently applying the proportions of the 5th and 10th hospitals, respectively, to the whole group.

RESULTS

The number of day care admissions rose from 172,000 (9.9% of all admissions) to 649,000 (29.1%). Of all interventions studied, the percentage carried out in day care increased; the percentages varied greatly from one hospital to another. In 1995, the mean number of interventions in daytime was 115,000 (57% of all 201,000 interventions). The shift from interventions during hospitalization to day care would be 42,000 and 51,000 (21% and 25% respectively, of 201,000), respectively; operations performed in day care would then amount to 166,000 (83% of the total number of interventions) and 157,000 (78%).

CONCLUSION

Of the interventions studied, the proportion carried out in day care increased to 57%. In view of the intra- and interhospital differences, a considerable increase of day care in the near future is possible.
