The management of foreign bodies in the gastrointestinal tract is not standardized. Foreign body ingestions in prisoners are always intentional and inmates can be manipulative, which makes medical decision even more difficult. Our objective is to propose a decisional algorithm for management of foreign body ingestion in prisoners. We reviewed the records of 198 admissions for foreign body ingestion for a 10-year period. Type and number of ingested foreign bodies, radiographic findings, outcome as well as the management method including conservative, endoscopic removal, or surgical treatment were analyzed. Most cases were managed conservatively (87.6%). Endoscopy of the upper gastrointestinal tract was performed in 37 cases with a success rate of 46 per cent. In 9.3 per cent of cases, the final treatment was endoscopic. Only five patients required surgical treatment, being emergent just in one case. We advocate conservative treatment for asymptomatic patients with foreign body ingestion. Endoscopic removal is proposed for pointed objects or objects bigger than 2.5 cm located in the stomach. Objects longer than 6 to 8 cm located in the stomach should be removed by endoscopy or laparoscopy. Patients with objects in the small bowel or colon should be treated conservatively unless there are complications or they fail to progress.

Background Transanal total mesorectal excision (TaTME) is a minimally invasive surgical technique that tries to avoid conversion to open surgery. However, specific intraoperative complications and local recurrences have cast some doubt on the suitability of the technique. The primary endpoint of the present study was a composite outcome of conversion surgery. Secondary objectives were to assess postoperative recovery, and pathological and oncological outcomes. Methods This was a prospective, multicentre, randomized, controlled open-label study of patients diagnosed with mid and low rectal adenocarcinoma who underwent laparoscopic TaTME or laparoscopic total mesorectal excision (LaTME). The TaTME technique comprised intracorporeal resection and anastomosis. Main outcomes were conversion to open surgery. Secondary outcomes were postoperative morbidity, mortality, pathological, oncological results, and survival. Modified intention-to-treat (mITT) and per-protocol analyses were performed. Results The study was conducted between April 2015 and May 2021. Patients were randomized to the LaTME (57 patients) or TaTME (59) group. Fifty patients from the LaTME group and 55 from the TaTME group were eligible for mITT analysis. The procedure was converted to open surgery in 11 patients (11 per cent): 10 (20 per cent) in the LaTME group and 1 (2 per cent) in the laparoscopic TaTME group (difference 18.8, 95 per cent c.i. 30 to 7; P = 0.003). No significant differences were found in terms of postoperative recovery and morbidity at 30 days; nor were there significant differences in anastomotic leakage, although it was less common in laparoscopic TaTME. With a median follow-up of 39 months, there were three instances of local recurrence (6.1 per cent) in the LaTME group and one (1.8 per cent) in the laparoscopic TaTME group (95 per cent c.i. 60 to 69; P = 0.3). Registration number: NCT02550769 (http://www.clinicaltrials.gov). Conclusion The conversion rate was significantly lower in laparoscopic TaTME than in LaTME. At centres with experienced surgeons, laparoscopic TaTME can avoid conversion to open surgery.

Introduction Transanal total mesorectal excision (TaTME) has rapidly emerged as a novel approach for rectal cancer surgery. Safety profiles are still emerging and more comparative data is urgently needed. This study aimed to compare indications and short‐term outcomes of TaTME, open, laparoscopic, and robotic TME internationally. Methods A pre‐planned analysis of the European Society of Coloproctology (ESCP) 2017 audit was performed. Patients undergoing elective total mesorectal excision (TME) for malignancy between 1 January 2017 and 15 March 2017 by any operative approach were included. The primary outcome measure was anastomotic leak. Results Of 2579 included patients, 76.2% (1966/2579) underwent TME with restorative anastomosis of which 19.9% (312/1966) had a minimally invasive approach (laparoscopic or robotic) which included a transanal component (TaTME). Overall, 9.0% (175/1951, 15 missing outcome data) of patients suffered an anastomotic leak. On univariate analysis both laparoscopic TaTME (OR 1.61, 1.02–2.48, P = 0.04) and robotic TaTME (OR 3.05, 1.10–7.34, P = 0.02) were associated with a higher risk of anastomotic leak than non‐transanal laparoscopic TME. However this association was lost in the mixed‐effects model controlling for patient and disease factors (OR 1.23, 0.77–1.97, P = 0.39 and OR 2.11, 0.79–5.62, P = 0.14 respectively), whilst low rectal anastomosis (OR 2.72, 1.55–4.77, P < 0.001) and male gender (OR 2.29, 1.52–3.44, P < 0.001) remained strongly associated. The overall positive circumferential margin resection rate was 4.0%, which varied between operative approaches: laparoscopic 3.2%, transanal 3.8%, open 4.7%, robotic 1%. Conclusion This contemporaneous international snapshot shows that uptake of the TaTME approach is widespread and is associated with surgically and pathologically acceptable results.

Introduction The mainstay of management for locally advanced rectal cancer is chemoradiotherapy followed by surgical resection. Following chemoradiotherapy, a complete response may be detected clinically and radiologically (cCR) prior to surgery or pathologically after surgery (pCR). We aim to report the overall complete pathological response (pCR) rate and the reliability of detecting a cCR by conventional pre‐operative imaging. Methods A pre‐planned analysis of the European Society of Coloproctology (ESCP) 2017 audit was performed. Patients treated by elective rectal resection were included. A pCR was defined as a ypT0 N0 EMVI negative primary tumour; a partial response represented any regression from baseline staging following chemoradiotherapy. The primary endpoint was the pCR rate. The secondary endpoint was agreement between post‐treatment MRI restaging (yMRI) and final pathological staging. Results Of 2572 patients undergoing rectal cancer surgery in 277 participating centres across 44 countries, 673 (26.2%) underwent chemoradiotherapy and surgery. The pCR rate was 10.3% (67/649), with a partial response in 35.9% (233/649) patients. Comparison of AJCC stage determined by post‐treatment yMRI with final pathology showed understaging in 13% (55/429) and overstaging in 34% (148/429). Agreement between yMRI and final pathology for T‐stage, N‐stage, or AJCC status were each graded as ‘fair’ only (n = 429, Kappa 0.25, 0.26 and 0.35 respectively). Conclusion The reported pCR rate of 10% highlights the potential for non‐operative management in selected cases. The limited strength of agreement between basic conventional post‐chemoradiotherapy imaging assessment techniques and pathology suggest alternative markers of response should be considered, in the context of controlled clinical trials.
