Systematic review of functional outcomes and quality of life after transanal endoscopic microsurgery and transanal minimally invasive surgery: a word of caution

PURPOSE

The introduction of transanal endoscopic or minimally invasive surgery has allowed organ preservation for rectal tumors with good oncological results. Data on functional and quality-of-life (QoL) outcomes are scarce and controversial. This systematic review sought to synthesize fecal continence, QoL, and manometric outcomes after transanal endoscopic microsurgery (TEM) or transanal minimally invasive surgery (TAMIS).

METHODS

A systematic review of the literature including Medline, Embase, and the Cochrane Library databases was conducted searching for articles reporting on functional outcomes after TEM or TAMIS between January 1995 and June 2018. The evaluated outcome parameters were pre- and postoperative fecal continence (primary endpoint), QoL, and manometric results. Data were extracted using the same scales and measurement units as from the original study.

RESULTS

A total of 29 studies comprising 1297 patients were included. Fecal continence outcomes were evaluated in 23 (79%) studies with a wide variety of assessment tools and divergent results. Ten studies (34%) analyzed QoL changes, and manometric variables were assessed in 15 studies (51%). Most studies reported some deterioration in manometric scores without major QoL impairment. Due to the heterogeneity of the data, it was not possible to perform any pooled analysis or meta-analysis.

CONCLUSIONS

These techniques do not seem to affect continence by themselves except in minor cases. The possibility of worsened function after TEM and TAMIS should not be underestimated. There is a need to homogenize or standardize functional and manometric outcomes assessment after TEM or TAMIS.

Low anterior resection syndrome (LARS) in ovarian cancer patients - A multi-centre comparative cohort study

BACKGROUND

Low anterior resection syndrome (LARS) is a common functional disorder after low anterior resection impacting the quality of life. Data on LARS derives nearly exclusively from rectal cancer studies. Therefore, the study was designed to assess LARS in advanced epithelial ovarian cancer (EOC) patients, who underwent rectal resection and to compare it with a female rectal cancer cohort.

MATERIAL AND METHODS

A cross-sectional multi-centre analysis was performed on female patients suffering from either rectal or EOC who received a low anterior resection as part of their therapy regimen. None of the patients received pre- or postoperative radiotherapy. LARS was defined by using the validated LARS score and its severity was divided into "no", "minor" and "major LARS".

RESULTS

In total, 125 female patients (44.8% (n = 56) EOC vs. 55.2% (n = 69) rectal cancer patients) met the final inclusion criteria and were retrospectively analyzed. Baseline characteristics were comparable between the groups. Median follow-up was 22 (IQR 12-56) months. In total, 30.4% (n = 38) of the patient group reported bowel dysfunction after surgery. Rates of LARS were not significantly different between EOC and rectal cancer patients (major LARS 16.1% (n = 9) vs. 15.9% (n = 11); minor LARS 17.9% (n = 10) vs. 11.6% (n = 8); p = 0.984). The time interval between surgery and final assessment had no impact on the postoperative bowel function (p = 0.820).

CONCLUSION

LARS is a frequent and highly underreported postoperative disorder in EOC patients who require cytoreductive surgery with rectal resection. The functional outcome is comparable to female patients with rectal cancer who underwent low anterior resection without receiving radiotherapy.

Clinical characterization of patients with anal fistula during follow-up of anorectal abscess: a large population-based study

PURPOSE

Approximately 15-50% of patients with an anorectal abscess will develop an anal fistula, but the true incidence of this entity is currently unknown. The aim of the study was to determine the incidence of anorectal abscess and development of a fistula in a specific population area and to identify potential risk factors associated with demographic, socioeconomic and pre-existing disease (e.g. diabetes and inflammatory bowel disease).

METHODS

A longitudinal observational study was designed including a large cohort study in an area with 7,553,650 inhabitants in Spain 1st january 2014 to 31st december 2019. Adults who attended for the first time with an anorectal abscess and had a minimum of 1-year follow-up were included. The diagnosis was made using ICD-10 codes for anorectal abscess and anal fistula.

RESULTS

During the study period, we included 27,821 patients with anorectal abscess. There was a predominance of men (70%) and an overall incidence of 596 per million population. The overall incidence of anal fistula developing from abscesses was 20%, with predominance in men, and a lower incidence in the lowest income level. The cumulative incidence of fistula was higher in men and in younger patients (p < 0.0001). On multivariate analysis, patients aged 60-69 years (hazard ratio 2.0) and those with inflammatory bowel disease (hazard ratio 1.8-2.0) had a strong association with fistula development (hazard ratio 2.0).

CONCLUSIONS

One in five patients with an anorectal abscess will develop a fistula, with a higher likelihood in men. Fistula formation was strongly associated with inflammatory bowel disease.

Is percutaneous sigmoidopexy a usefull aternative to high surgical risk patients to treat sigmoid volvulus?

This article presents two cases of elderly patients with recurrent sigmoid volvulus and significant comorbidities, making them unsuitable for surgery. Instead, percutaneous sigmoidopexy assisted by colonoscopy was performed. The procedure involved percutaneous puncture and fixation using T-sutures and endoscopic clips. Both patients were discharged without complications and experienced no recurrence of volvulus six months post-procedure. The article highlights the need for further research to validate this method as an alternative to surgery for high-risk patients.

Recipient Age for Liver Transplantation: Should It Be Limited? A Propensity Score Matching Analysis of a Large European Series

BACKGROUND AND AIMS

The demand for older patients not to be denied access to liver transplantation (LT) has intensified as the European population continues to live longer and maintains better health.

AIM

This study aims to ascertain the impact of recipient age on the post-LT survival in 2 well-balanced populations at Vall d'Hebron University Hospital.

METHODS

From January 1990 to December 2016, LT recipients (young group: 50-65 years of age; elderly group: >65 years of age) were compared by means of a propensity score matching (PSM) method.

RESULTS

Prior to PSM, graft survival and patient survival were worse for the elderly group (P < .001). In 1126 LT recipients, a caliper width of 0.01 was used based on the donor (age, sex, cause of donor death, and donor intensive care unit stay) and recipient covariates (sex, body mass index, indication for LT, intraoperative blood transfusion, cardiovascular risk factors, and Model for End-Stage Liver Disease [MELD]-Era). After PSM, 206 patients were matched; 1-, 5-, and 10-year patient survival rates were 77%, 63%, and 52% vs 80%, 64%, and 45% (P = .50) for young vs elderly recipients, respectively. Similar graft survival rates were observed in both groups (P = .42).

CONCLUSIONS

Advanced age alone should not exclude patients from LT.
