Abstract Aims Transanal-endoscopic microsurgery (TEMS) for early rectal cancer is an attractive alternative to radical surgery. With proper patient selection, it is possible to achieve acceptable oncological outcomes with fewer complications. We aim to study the outcomes following TEMS for suspicious or proven rectal cancers performed in our unit. Method We performed a retrospective analysis of prospectively collected data between May-17 and Oct-20. The patients’ details, tumour specific data, short term outcomes, and recurrences were recorded. Results A total of 45 patients with early rectal cancer (M = 29, F = 15) were included in this study. With1 exclusion due to intraoperative rectal perforation, 44 were available for further analysis. Eleven had a diagnosis of cancer at the time of surgery, an additional 11 patients were confirmed on final histology, and 22 were benign. Final histology showed: T1=14, T2=4, T3=3 &Tx=1. The majority (68%) had clear resection margins (R1=3, R2=1, Rx = 3). Twelve patients went on to have further treatment. Seven had resectional surgery (AR = 5, APR=2) for unfavorable histology (2), residual disease (3), or recurrence (2). The other 5(23%) received chemotherapy+/-radiotherapy (unfit/patients’ choice) for unfavorable. Histology (3) or residual disease (2). Conclusion With judicious patient selection, it is possible to offer a less invasive option with acceptable oncological and patient related outcomes for suspicious and proven malignant rectal lesions. The majority of patients (84%) were able to avoid radical surgery or stoma, thereby reducing the associated morbidity. Whilst this is a single institution study, we believe with available expertise this could be widely replicated.

AbstractDespite multiple studies, there remains a debate on the safety of bilateral total knee arthroplasty (BTKA) in the average age patient, with a paucity of data on the outcome of BTKA in an elderly population. This study included 89 patients aged 80 years and older undergoing sequential BTKA over 14 years were identified in a prospectively collected database. Two matched comparison groups were created: patients under 80 undergoing sequential BTKA and patients over 80 undergoing unilateral TKA (UTKA). An analysis of complications, mortality, revision, and patient-reported outcome measures was performed. Mean age of the elderly cohorts was similar: 82.6 for BTKA and 82.9 for UTKA. The average age BTKA cohort had a mean age of 69.1. Complication rates were higher in bilateral cohorts, more so in the elderly BTKA cohort. Pulmonary embolism (PE) was observed in bilateral cohorts only. In these patients, history of PE and ischemic heart disease was a strong predictive factor for developing a major complication. There was no difference in revision rates and infection rates between the three cohorts, and no difference in patient survivorship between the two elderly cohorts. Through the combination of low revision and high survivorship rates and comparable clinical outcomes, this article demonstrates that simultaneous BTKA is an appropriate option to consider for an elderly patient, with proper patient selection and perioperative management. The demonstrated risk groups show that emphasis on patient selection should be focused on medical history rather than chronological age.

Prognostic Nutrition Index

Abstract Background Local recurrence is common after curative resections for rectal cancer. Surgical intervention is among the best treatment choices. However, achieving a negative resection margin often requires extensive pelvic organ resections; thus, the postoperative complication rate is quite high. Recent studies have reported that the inflammatory index could predict postoperative complications. This study aimed to validate the correlation between clinical factors, including inflammatory markers, and severe complications after surgery for local recurrent rectal cancer. Methods This retrospective study included 99 patients that underwent radical resections for local recurrences of rectal cancer. Postoperative complications were graded according to the Clavien-Dindo classification. Grades ≥3 were defined as severe complications. Risk factors for severe complications were identified with univariate and multivariate logistic regression models and assessed with receiver-operating characteristic curves. Results Severe postoperative complications occurred in 38 patients (38.4%). Analyses of correlations between inflammatory markers and severe postoperative complications revealed that the strongest correlation was found between the prognostic nutrition index and severe postoperative complications. The receiver-operating characteristic analysis showed that the optimal prognostic nutrition index cut-off value was 42.2 (sensitivity: 0.790, specificity: 0.508). In univariate and multivariate analyses, a prognostic nutrition index ≤44.2 (Odds ratio: 3.007, 95%CI:1.171–8.255, p = 0.02) and a blood loss ≥2850 mL (Odds ratio: 2.545, 95%CI: 1.044–6.367, p = 0.04) were associated with a significantly higher incidence of severe postoperative complications. Conclusions We found that a low preoperative prognostic nutrition index and excessive intraoperative blood loss were risk factors for severe complications after surgery for local recurrent rectal cancer.

Dosimetric Data

Abstract Introduction Radiotherapy for locally advanced rectal cancer is conventionally performed using photon-based radiotherapy (PBR), carrying significant risk of toxicity to organs at risk (OAR). Proton beam therapy (PBT) potentially delivers equivalent dosimetric radiation to the targeted tissue with improved sparing of OAR. We aimed to compare dosimetric irradiation of OAR for PBT versus PBR in patients with rectal cancer and assess any oncological outcomes. Method An extensive electronic literature search was performed from inception till April 2020 and subsequent meta-analysis performed. Results Six articles met the inclusion criteria. Dosimetric data of irradiation delivered to OAR for PBT and PBR were calculated for the same patients. PBT had significantly less irradiated small bowel compared to 3DCRT and IMRT, (MD -16.95, 95% CI [-24.03, -9.88], p < 0.00001) and (MD -6.96, 95% CI [-12.99, -0.94], p = 0.02) respectively. Similar results were observed for bladder and pelvic bone marrow. Two studies reported clinical and oncological results for PBT in recurrent rectal cancer with overall survival reported as 43% and 68%. Conclusions Dosimetric treatment plans have less irradiation of OAR for rectal cancer with PBT compared to PBR. There is a need for further research in PBT and rectal cancer, as promising results have been shown in recurrent rectal cancer.
