Managing Recurrent Teratoma in Currarino Syndrome.

To the best of our knowledge, this is the first reported case of a recurrent presacral tumor in Currarino syndrome. Currarino syndrome is a rare disease usually found in childhood with a triad of sacral agenesis, anorectal malformation, and presacral tumor. However, it can often remain undiscovered until adulthood. Currarino syndrome is generally diagnosed during childhood in the setting of recurrent meningitis and is often suspected when there is a family history. Occasionally, it is diagnosed in adulthood through incidental imaging or due to investigations for back pain and chronic constipation. MRI is the recommended imaging modality in this disease process, as it can better help differentiate soft tissue. The tumor can be resected through either the transabdominal approach or the posterior approach (Kraske procedure). We present a 52-year-old female patient who was diagnosed with Currarino syndrome when she was one year old due to recurrent meningitis and surgical resection of a presacral mass and was asymptomatic until she developed back pain and constipation. Her symptoms were investigated with an MRI, revealing a recurrence of a presacral tumor, and she subsequently underwent a Kraske procedure. The patient is currently under annual surveillance, and the residual tumor has remained stable. There are currently no surveillance guidelines after resection of a presacral tumor in Currarino Syndrome. However, follow-up surveillance should be considered.

Right hemicolectomy for colon cancer: does the anastomotic configuration affect short-term outcomes?

OBJECTIVES: Right hemicolectomy is a common colorectal operation for resection of cancers of the right colon. The ileocolic anastomosis may be created using a stapled end-to-side, stapled side-to-side or handsewn technique. Anastomotic leak and post-operative bleeding are uncommon but serious causes of morbidity and mortality, while post-operative ileus contributes to prolonged length of stay. The aim of this study was to evaluate differences in short-term outcomes between different anastomotic configurations following right hemicolectomy for colon cancer. METHODS: We conducted a retrospective study using data from the Bowel Cancer Outcomes Registry (BCOR), including 94 hospitals across Australia and New Zealand, of all patients who underwent right hemicolectomy or extended right hemicolectomy for colon cancer with formation of a primary anastomosis between 2007 and 2021. RESULTS: We included 8164 patients in the analysis. There was no significant difference in rates of anastomotic leak and anastomotic bleeding based on anastomotic technique. A stapled end-to-side anastomosis was associated with a lower rate of post-operative ileus than stapled side-to-side anastomosis (6.5% vs. 7.2%; P = 0.03). CONCLUSION: Both handsewn and stapled anastomosis techniques may be utilized for oncologic right hemicolectomy, with comparable rates of anastomotic leak and post-operative bleeding. Stapled end-to-side anastomosis resulted in lower rates of prolonged ileus compared to stapled side-to-side anastomoses.

Comparison of quality of life, symptom and functional outcomes following surgical treatment for colorectal neoplasia.

BACKGROUND: Colorectal surgical procedures can have a significant impact on quality-of-life (QoL), functional and symptom outcomes. This retrospective study conducted in a tertiary care center evaluated the influence of four colorectal surgical procedures on patient-reported outcome measures (PROMs). METHODS: 512 patients undergoing colorectal neoplasia surgery between June 2015 and December 2017 were identified via the Cabrini Monash Colorectal Neoplasia database. Primary outcomes measured were the mean changes in PROMs following surgery utilizing the International Consortium of Health Outcome Measures colorectal cancer (CRC) PROMs. RESULTS: 242 patients from 483 eligible patients responded (50% participation rate). Responders and non-responders were comparable in median age (72 vs. 70 years), gender (48% vs. 52% male), time from surgery (<1 and >1 year), overall stage at diagnosis and type of surgery. Respondents underwent either a right hemicolectomy, ultra-low anterior resection, abdominoperineal resection or a transanal endoscopic microsurgery/transanal minimally invasive surgery. Right hemicolectomy patients reported the best post-operative function and reduced symptoms, significantly better (P < 0.01) than ultra-low anterior resection patients who reported the worst outcomes in multiple areas (body image, embarrassment, flatulence, diarrhoea, stool frequency). Furthermore, patients undergoing an abdominoperineal resection reported the worst scores for body image, urinary frequency, urinary incontinence, buttock pain, faecal incontinence and male impotence. CONCLUSIONS: The differences in PROMs in CRC surgical procedures is demonstrable. The worst post-operative functional and symptom scores were reported after either an ultra-low anterior resection or an abdominoperineal resection. Implementation of PROMs will identify and aid early patient referral to allied health and support services.

Mechanical bowel preparation with pre-operative oral antibiotics in elective colorectal resections: an Australian single institution experience.

BACKGROUND: Anastomotic leaks (AL) and surgical site infections (SSI) are serious complications after colorectal resection. Studies have shown the benefits of pre-operative oral antibiotics (OAB) with mechanical bowel preparation (MBP) in reducing AL and SSI rates. We aim to investigate our experience with the short-term outcomes of AL and SSI following elective colorectal resections in patients receiving OAB with MBP versus MBP only. METHODS: A retrospective analysis was performed from our database for patients who underwent elective colorectal resection between January 2019 and November 2021. Prior to August 2020, OAB was not used as part of MBP. After 2020, Neomycin and Metronidazole were used in conjunction with MBP. We evaluated differences in AL and SSI between both groups. RESULTS: Five hundred and seventeen patients were included from our database with 247 having MBP while 270 had OAB and MBP. There was a significantly lower rate of AL in patients receiving MBP and OAB as compared to MBP alone (0.4% versus 3.0%, P-value = 0.03). The SSI rate at our institution was 4.4%. It was lower in patients with MBP and OAB as compared to MBP alone, but this was not clinically significant (3.3% versus 5.7%, P-value = 0.19). CONCLUSION: The association in the reduction of AL with the addition of OAB to the MBP protocol seen here reinforces the need for future randomized controlled trials in the Australasian context. We recommend colorectal institutions in Australian and New Zealand consider OAB with MBP as part of their elective colorectal resection protocol.

Factors affecting the post-operative outcomes in patients aged over 80 following colorectal cancer surgery.

PURPOSE: In 2019, in Australia, there were 500,000 people aged 85 and over. Traditionally, clinicians have adopted the view that surgery is not desirable in this cohort due to increasing perioperative risk, perceived minimal clinical benefit, and shortened life expectancy. This cohort study is aimed at investigating postoperative outcomes from elective and non-elective colorectal cancer surgery in patients aged 80 and over. METHODS: A retrospective analysis was conducted on patients from 2010 to 2020 on a prospectively maintained colorectal database. Patients aged over 80 who underwent surgical resection for colorectal cancer were reviewed. Oncological characteristics, short-term outcomes, overall survival, and relapse-free survival rates were analysed. RESULTS: A total of 832 patients were identified from the database. Females comprised 55% of patients aged 80 and above. The median age was 84 for octogenarians and 92 for nonagenarians. Most patients were ASA 2 (212) or ASA 3 (501). ASA 3 and 4 and stage III pathology were associated with higher postoperative complications. Fifty percent of over 80 s and 37% of over 90 s were surgically discharged to their own home. Overall survival at 30, 180, and 360 days and 5 years was 98.1%, 93.1%, 87.2%, and 57.2% for the over 80 s and 98.1%, 88.9%, 74.9%, and 24.4% for the over 90 s. CONCLUSION: Our results demonstrate that surgical treatment of older patients is safe with acceptable short-, medium-, and long-term survival. Nonetheless, efforts are needed to reduce the rates of complications in older patients, including utilisation of multi-disciplinary teams to assess the optimal treatment strategy and postoperative care.

Impact of Anastomotic Leak on Long-term Oncological Outcomes After Restorative Surgery for Rectal Cancer: A Retrospective Cohort Study.

BACKGROUND: Anastomotic leak after restorative surgery for rectal cancer is a major complication and may lead to worse long-term oncological and survival outcomes. OBJECTIVE: The purpose of this study was to identify risk factors associated with anastomotic leak and to assess the perioperative and long-term oncological impact of anastomotic leak in our cohort of patients with rectal cancer. DESIGN: A retrospective analysis was performed on data from the prospectively maintained Cabrini Monash colorectal neoplasia database. Patients who had undergone rectal cancer resection and subsequently received anastomosis between November 2009 and May 2020 were included in this study. Patient and tumor characteristics, technical risk factors, and short-term and perioperative as well as long-term oncological and survival outcomes were assessed. SETTINGS: The study was conducted in 3 tertiary hospitals. PATIENTS: A total of 693 patients met the inclusion criteria for this study. MAIN OUTCOME MEASURES: Univariate analyses were performed to assess the relationship between anastomotic leak and patient and technical risk factors, as well as perioperative and long-term outcomes. Univariate and multivariate proportional HR models of overall and disease-free survival were calculated. Kaplan-Meier survival analyses assessed disease-free and overall survival. RESULTS: Anastomotic leak rate was 3.75%. Males had an increased risk of anastomotic leak, as did patients with hypertension and ischemic heart disease. Patients who experience an anastomotic leak were more likely to require reoperation and hospital readmission and were more likely to experience an inpatient death. Disease-free and overall survival were also negatively impacted by anastomotic leaks. LIMITATIONS: This is a retrospective analysis of data from only 3 centers with the usual limitations. However, these effects have been minimized because of the high quality and completeness of the prospective data collection. CONCLUSIONS: Anastomotic leaks after restorative surgery negatively affect long-term oncological and survival outcomes for patients with rectal cancer.

A comparison of extracorporeal side to side or end to side anastomosis following a laparoscopic right hemicolectomy for colon cancer.

BACKGROUND: This study aimed to investigate whether an extracorporeal side-to-side (SS) or end-to-side (ES) stapled anastomosis impacts short-term and long-term outcomes after an oncological laparoscopic right hemicolectomy. METHODS: A retrospective cohort study of prospectively collected data from two Victorian tertiary referral hospitals was performed. Patients who underwent oncological resection for colorectal cancer between February 2010 and September 2020 were selected from the colorectal neoplasia database. Patients were divided into two groups depending on the type of stapled anastomosis: Group 1 (functional end-to-end/side-to-side (SS)); and Group 2 (end-to-side (ES)). Primary outcomes were anastomotic leak, postoperative ileus, mortality and morbidity, length of stay post-surgery, readmission to hospital, and 30-day mortality. RESULTS: This large case series of 1040 patients (SS = 625, ES = 415) demonstrated that the type of stapling technique impacted operative duration and postoperative ileus rates. Patients in the SS group had a faster operation of 108 min rather than 130 min in the ES group (p < 0.001). The SS group were more likely to experience a post-operative ileus (p < 0.001) with no impact on length of stay (SS, 7 days versus ES, 7 days; p = 0.14). There were no differences between the two groups with respect to lymph node yield, lymph node ratio, anastomotic leaks, return to theatre, 30-day mortality and 5-year overall survival. DISCUSSION: The type of extracorporeal stapled anastomosis following an oncological laparoscopic right hemicolectomy has minimal impact on morbidity and survival outcomes; however, a side-to-side stapled anastomosis is more likely to be a faster operation with a higher postoperative ileus rate.
