Oncologic Outcomes After Transanal Total Mesorectal Excision for Rectal Cancer.

BACKGROUND: Recent series have raised concerns about the oncologic outcomes of transanal total mesorectal excision for mid and low rectal cancer. There is a paucity of large data sets from the United States to contribute to the ongoing international discourse. OBJECTIVE: This study aimed to investigate the rate of local recurrence and other oncologic outcomes in patients undergoing transanal total mesorectal excision for rectal adenocarcinoma. DESIGN: This study is a retrospective review of patients undergoing transanal total mesorectal excision for primary rectal cancer from January 2014 to December 2019. SETTINGS: This study was conducted at a single academic tertiary care medical center in the United States. PATIENTS: Consecutive patients aged ≥18 years undergoing surgical resection for primary rectal cancer were selected. INTERVENTION: The transanal total mesorectal excision procedures were performed utilizing a 2-team approach. MAIN OUTCOME MEASURES: Primary outcomes were pathologic quality, local and distant recurrence, treatment-related complications, and overall- and cancer-specific survival. RESULTS: Seventy-nine consecutive patients were included. The median age was 58 years (interquartile range, 50-64), and median BMI was 28 kg/m2 (interquartile range, 24.6-32.4). The mesorectum was complete in 69 patients (87.3%), nearly complete in 9 (11.4%), and incomplete in 1 (1.3%). There was circumferential resection margin involvement (<1 mm) in 4 patients (5.1%), and no patients had a positive distal margin (<1 mm) or intraoperative rectal perforation. Composite optimal pathology was achieved in 94.9% of specimens. Median follow-up was 29 months (range, 6-68). There were no local recurrences. Distant metastases were found in 10 (13.5%) patients and diagnosed after a median of 14 months (range, 0.6-53). Disease-free survival was 91.2% at 2 years, and overall survival was 94.7% at 2 years. LIMITATIONS: Retrospective design, a single center, and relatively short follow-up period were limitations of this study. CONCLUSION: The oncologic outcomes of this cohort support the use of transanal total mesorectal excision in the surgical management of mid to low rectal cancer at centers with appropriate expertise.

Transanal Minimally Invasive Surgery: An Effective Approach for Patients Who Require Redo Pelvic Surgery for Anastomotic Failure.

BACKGROUND: Anastomotic leaks cause significant patient morbidity that may require redo pelvic surgery. Transanal minimally invasive surgery facilitates direct access to the pelvis with increased visualization and maneuverability for technically difficult redo surgery. OBJECTIVE: This study aimed to assess the feasibility and outcomes of transanal minimally invasive surgery in redo proctectomy for anastomotic complications. DESIGN: This was a retrospective cohort study. SETTINGS: This study was conducted at a single tertiary-care institution. PATIENTS: Consecutive patients undergoing transanal minimally invasive redo proctectomy were included. INTERVENTIONS: Transanal minimally invasive redo proctectomy was performed. MAIN OUTCOME MEASURES: The primary end point was intraoperative feasibility. The secondary end points were safety, perioperative morbidity, and symptom resolution. RESULTS: Seven patients underwent redo proctectomy via transanal minimally invasive surgery for anastomotic defect (n = 6) or stricture (n = 1). Median time from initial to redo operation was 27 months (range, 13-67). Redo proctectomy included redo low anterior resection with coloanal anastomosis and diverting loop ileostomy (n = 4), completion proctectomy with end colostomy (n = 2), and pouch resection with end ileostomy (n = 1). Six patients had an open abdominal approach. There were no conversions for the anal approach. Median operative time was 6.4 hours (range, 4.0-7.1). All 4 planned redo coloanal anastomoses were successfully created. Hospital length of stay was a median of 8 days (interquartile range, 6-9). Intraoperative complications included 2 patients with carbon dioxide emboli, which resolved with supportive care; there was no adjacent organ injury. Three patients were readmitted within 30 days. There were no postoperative anastomotic leaks, and all 4 patients with diverted ileostomies underwent reversal at a median of 4 months (interquartile range, 4-6). All symptoms prompting redo surgery remain resolved at a median follow-up of 20 months. LIMITATIONS: This study was limited by its small sample size and its single-institution focus. CONCLUSION: For those with expertise in transanal surgery, transanal minimally invasive surgery is a safe and effective option for patients with anastomotic failure requiring redo proctectomy because it provides direct access to and visualization of the pelvis.

Hartmann's reversal: factors affecting complications and outcomes.

AIM: Hartmann's procedure is commonly performed emergently for infectious, inflammatory, or malignant processes. Most patients historically do not undergo reversal, and those who do have been found to suffer significant morbidity. The aim of this study was to study factors associated with complications after Hartmann's reversal and to provide information and guidance to surgeons. METHOD: A retrospective review of patients undergoing Hartmann's reversal between May 2002 and October 2017 was conducted at a tertiary medical center. Data included patient characteristics at the time of surgery and intra- and postoperative complications. Chi-square test was used for categorical variables. The Wilcoxon signed rank or t test where appropriate was used for multivariate analysis. RESULTS: Two hundred forty-nine patients were included. Mean age at reversal was 58.8 years, and 114 (58%) were male. Sixty-two (31.8%) patients experienced a major complication following reversal. Eight (4%) patients had an anastomotic leak. Thirteen (6.67%) patients had an intra-abdominal abscess which required either IR or operative drainage. Patients who experienced a major complication were more likely to have an ASA 4 at time of reversal (14.3% vs. 4.24%, p = 0.019), liver disease (6.6% vs. 0.8%, p = 0.021), and BMI < 30 (35% vs. 17.3%, p = 0.020). CONCLUSIONS: Nearly one-third of patients who had reversal surgery experienced a major complication. Four percent of patients undergoing reversal had an anastomotic leak, comparable to previously reported rates. Patients with ASA 4, liver disease, and BMI < 30 were at higher risk of a major complication following reversal. Patients who underwent laparoscopic reversal had no significant difference in outcomes. AIM: What does this paper add to the literature? The decision of whether to reverse a colostomy after Hartmann's procedure. Our study aims to identify risk factors associated with complications after Hartmann's reversal to better guide surgeon's facing the dilemma of whether or not to reverse the stoma.

Transanal Total Mesorectal Excision for Rectal Cancer.

Transanal total mesorectal excision (taTME) is a technique where rectal dissection is begun transanally in a "bottom-up" fashion. This technique facilitates dissection of the most distal part of the rectum and allows the establishment of the distal margin for rectal cancer. TaTME has proven its utility in facilitating low rectal dissection with significantly lower conversion rates and acceptable perioperative, oncological, and functional outcomes. However, taTME remains a challenging technique to learn and adopt. This article describes the technique, indications, and outcomes of taTME in rectal cancer during the last decade.

Environments and autistic spectrum conditions.

Sensory differences for people with autistic spectrum conditions (ASC) have considerable impacts on their experiences and ability to function. In hospitals and other care settings, it may be difficult for this group to feel safe and comfortable. This article highlights the sensory differences and needs of people with ASC, and the impact that failure to understand these differences can have on them and those around them. It outlines nurses' roles in assessment, planning, intervention and management of the environment.

Technological Advances in the Surgical Treatment of Colorectal Cancer.

Efforts toward standardization of surgical techniques have facilitated adoption of oncologic resections for colorectal cancer with associated improvement in outcomes. With the introduction of laparoscopy, total mesorectal excision (TME) and complete mesocolic excision (CME) techniques were progressively adapted to the minimally invasive surgery (MIS) approach with significant benefits with regards to patient recovery and comparable oncologic outcomes when performed by surgeons beyond their learning curve. Anastomotic complications and functional disturbances following TME remain significant. Recent innovations include intracorporeal anastomosis, which avoids midline extraction sites, and transanal TME, which lowers conversion rates and facilitates sphincter preservation for low rectal tumors.

Community mental health nursing and early intervention in dementia: developing practice through a single case history.

People Nursing in association with Journal of Clinical Nursing 13, 6b, 57-67 Community mental health nursing and early intervention in dementia: developing practice through a single case history This paper reports on a single case history taken from the 'Dementia Action Research and Education' project, a 15-month primary care intervention study that was undertaken in North Wales in the early part of 2000. The study sought to address the meaning, context and diversity of early intervention in dementia care and employed a community mental health nurse and a psychiatric social worker to undertake early and psychosocial interventions with older people with dementia (aged 75 years and over) and their families. The workers tape-recorded, documented and analysed their interventions with 27 older people with dementia and their families over the 15-month duration of the study. Clinical supervision was also undertaken during the intervention phase. One case history is presented in this paper to illustrate the work of the community mental health nurse and to identify areas of practice development. Greater role transparency, collaborative working and improvement in educational preparation for practice are called for.
