RESUMO
INTRODUCTION: Robotic transanal minimally invasive surgery (R-TAMIS) was introduced in 2012 for the excision of benign rectal polyps and low grade rectal cancer. Ergonomic improvements over traditional laparoscopic TAMIS (L-TAMIS) include increased dexterity within a small operative field, with possibility of better surgical precision. We aim to collate the existing data surrounding the use of R-TAMIS to treat rectal neoplasms from cohort studies and larger case series, providing a foundation for future, large-scale, comparative studies. METHODS: Medline, EMBASE and Web of Science were searched as part of our review. Randomised controlled trials (RCTs), cohort studies or large case series (≥ 5 patients) investigating the use of R-TAMIS to resect rectal neoplasia (benign or malignant) were eligible for inclusion in our analysis. Quality assessment of included studies was performed via the Newcastle Ottawa Scale (NOS) risk of bias tool. Outcomes extracted included basic participant characteristics, operative details and histopathological/oncological outcomes. RESULTS: Eighteen studies on 317 participants were included in our analysis. The quality of studies was generally satisfactory. Overall complication rate from R-TAMIS was 9.7%. Clear margins (R0) were reported in 96.2% of patients. Local recurrence (benign or malignant) occurred in 2.2% of patients during the specified follow-up periods. CONCLUSION: Our review highlights the current evidence for R-TAMIS in the local excision of rectal lesions. While R-TAMIS appears to have complication, margin negativity and recurrence rates superior to those of published L-TAMIS series, comparative studies are needed.

BACKGROUND: Acute surgical units (ASU) are increasingly being adopted and in our system are staffed by colorectal and non-colorectal general surgeons. This study aims to evaluate whether surgeon specialization was associated with improved outcomes in perianal abscess. METHODS: Patients with perianal abscess admitted to the ASU between 2016 and 2020 were identified from a prospective database and their medical records reviewed. Patients with IBD, treatment for fistula-in-ano within the preceding year, or perianal sepsis of non-cryptoglandular origin were excluded. Patients admitted under an ASU colorectal (CR) consultant were compared with those under a non-CR general surgeon in a retrospective cohort study. Primary outcome was perianal abscess recurrence. For those without initial fistula, hazard of recurrent abscess or fistula was analysed. Multivariable Cox PH regression analysis was performed. RESULTS: Four-hundred and eight patients were included (150 CR, 258 non-CR). The CR group more frequently had a fistula identified at index operation (34.0% versus 10.9%, P < 0.0001). However, Cox multivariable analysis found no difference in hazard of recurrent abscess between groups (HR 1.12, 95% CI 0.65-1.95, P = 0.681)). Abscess recurred in 18.7% CR and 15.5% non-CR. Subsequent fistula developed in 14.7% in both groups. For patients without initial fistula, there was no difference between groups in hazard of recurrent abscess or fistula (HR 1.18, 95% CI 0.69-2.01, P = 0.539). CONCLUSION: Surgeon specialization was not associated with improved outcomes for ASU patients with perianal abscess, albeit with potential selection bias. CR surgeons were more proactive identifying fistulas; this raises the possibility that drainage alone may be adequate treatment.

INTRODUCTION: Historically, surgical resection for patients with locally recurrent rectal cancer (LRRC) had been reserved for those without metastatic disease. 'Selective' patients with limited oligometastatic disease (OMD) (involving the liver and/or lung) are now increasingly being considered for resection, with favourable five-year survival rates. METHODS: A retrospective analysis of consecutive patients undergoing multi-visceral pelvic resection of LRRC with their oligometastatic disease between 1 January 2015 and 31 August 2021 across four centres worldwide was performed. The data collected included disease characteristics, neoadjuvant therapy details, perioperative and oncological outcomes. RESULTS: Fourteen participants with a mean age of 59 years were included. There was a female preponderance (n = 9). Nine patients had liver metastases, four had lung metastases and one had both lung and liver disease. The mean number of metastatic tumours was 1.5 +/- 0.85. R0 margins were obtained in 71.4% (n = 10) and 100% (n = 14) of pelvic exenteration and oligometastatic disease surgeries, respectively. Mean lymph node yield was 11.6 +/- 6.9 nodes, with positive nodes being found in 28.6% (n = 4) of cases. A single major morbidity was reported, with no perioperative deaths. At follow-up, the median disease-free survival and overall survival were 12.3 months (IQR 4.5-17.5 months) and 25.9 months (IQR 6.2-39.7 months), respectively. CONCLUSIONS: Performing radical multi-visceral surgery for LRRC and distant oligometastatic disease appears to be feasible in appropriately selected patients that underwent good perioperative counselling.
RESUMO
BACKGROUND: Although several studies compare the clinical outcomes and costs of laparoscopic and robotic proctectomy, most of them reflect the outcomes of the utilisation of older generation robotic platforms. The aim of this study is to compare the financial and clinical outcomes of robotic and laparoscopic proctectomy within a public healthcare system, utilising a multi-quadrant platform. METHODS: Consecutive patients undergoing laparoscopic and robotic proctectomy between January 2017 and June 2020 in a public quaternary centre were included. Demographic characteristics, baseline clinical, tumour and operative variables, perioperative, histopathological outcomes and costs were compared between the laparoscopic and robotic groups. Simple linear regression and generalised linear model analyses with gamma distribution and log-link function were used to determine the impact of the surgical approach on overall costs. RESULTS: During the study period, 113 patients underwent minimally invasive proctectomy. Of these, 81 (71.7%) underwent a robotic proctectomy. A robotic approach was associated with a lower conversion rate (2.5% versus 21.8%;P = 0.002) at the expense of longer operating times (284 ± 83.4 versus 243 ± 89.8 min;P = 0.025). Regarding financial outcomes, robotic surgery was associated with increased theatre costs (A$23,019 ± 8235 versus A$15,525 ± 6382; P < 0.001) and overall costs (A$34,350 ± 14,770 versus A$26,083 ± 12,647; P = 0.003). Hospitalisation costs were similar between both approaches. An ASA ≥ 3, non-metastatic disease, low rectal cancer, neoadjuvant therapy, non-restorative resection, extended resection, and a robotic approach were identified as drivers of overall costs in the univariate analysis. However, after performing a multivariate analysis, a robotic approach was not identified as an independent driver of overall costs during the inpatient episode (P = 0.1). CONCLUSION: Robotic proctectomy was associated with increased theatre costs but not with increased overall inpatient costs within a public healthcare setting. Conversion was less common for robotic proctectomy at the expense of increased operating time. Larger studies will be needed to confirm these findings and examine the cost-effectiveness of robotic proctectomy to further justify its penetration in the public healthcare system.

BACKGROUND: The aim of this study is to explore the impact of the approach on conversion in patients undergoing minimally invasive restorative total mesorectal excision within a single unit. METHODS: A retrospective cohort study was conducted. Patients with rectal cancer undergoing minimally invasive restorative total mesorectal excision between January 2006 and June 2020 were included. Subjects were classified according to the presence or absence of conversion. Baseline variables and short-term outcomes were compared. Regression analyses were conducted to assess the relationship between the approach and conversion. RESULTS: During the study period, 318 patients underwent a restorative proctectomy. Of these, 240 met the inclusion criteria. Robotic and laparoscopic approaches were undertaken in 147 (61.3%) and 93 (38.8%) cases, respectively. A transanal approach was utilised in 62 (25.8%) cases (58.1% in combination with a robotic transabdominal approach). Conversion to open surgery occurred in 30 cases (12.5%). Conversion was associated with an increased overall complication rate (P = 0.003), surgical complications (P = 0.009), superficial surgical site infections (P = 0.02) and an increased length of hospital stay (P = 0.006). Robotic and transanal approaches were both associated with decreased conversion rates. The multiple logistic regression analysis, however, showed that only a transanal approach was independently associated with a lower risk of conversion (OR 0.147, 0.023-0.532; P = 0.01), whilst obesity was an independent risk factor for conversion (OR 4.388, 1.852-10.56; P < 0.00). CONCLUSIONS: A transanal component is associated with a reduced conversion rate in minimally invasive restorative total mesorectal excision, regardless of the transabdominal approach utilised. Larger studies will be required to confirm these findings and define which subgroup of patients could benefit from transanal component when a robotic approach is undertaken.

BACKGROUND: The role of en bloc vascular resection and reconstruction (EVRR) is controversial in colorectal adenocarcinoma (CRC), but well-established in retroperitoneal sarcoma (RPS). Sparse data exists regarding these complex procedures. METHODS: Patients undergoing curative intent EVRR for advanced CRC and RPS between 2014 and 2021 at a tertiary centre were included. Morbidity, margins, recurrence, and survival were evaluated. RESULTS: 24 patients underwent EVRR with 48 reconstructions (11 CRC and 13 RPS). For CRC, 100% of patients underwent Iliac system reconstructions. For RPS, inferior vena cava reconstructions were the most common (69.2%). There were 2 arterial and 1 venous graft thromboses. Primary graft patency was 89.4% arterial and 93.1% venous, while secondary patency was 100% arterial and 96.5% venous at last follow up. 1 venous and 1 arterial graft required reoperation for bleeding. There were no compromised limbs. Major complications occurred in 6 patients (25.0%) with no observed difference between CRC and RPS (OR 0.43 95%CI[0.60,3.19], P = 0.41). R1 margins occurred 1 CRC (90.9%) and 3 RPS (76.9%), with no R2 resections. All vascular resection margins were clear. There were 6 CRC (50%) and 4 RPS (33.3%) recurrences. Median recurrence time was 20.9 months for CRC and 'not yet reached' for RPS. Median follow-up was 19.4 months for CRC and 21.4 months for RPS. CONCLUSION: EVRR for locally advanced CRC or RPS is safe and achieves favorable R0 resection rates. CRC patients with major vascular invasion can still be considered for curative intent surgery. Larger cohorts with longer follow up are needed to assess oncologic outcomes.

INTRODUCTION: Minimally invasive surgical techniques are being successfully used to treat locally advanced and recurrent pelvic malignancy of colorectal origin. This review aims to describe the application of minimally invasive approaches to pelvic exenteration and compare current reported surgical outcomes. METHODS AND RESULTS: A literature search was performed of PubMed, Google Scholar and EMBASE for studies on pelvic exenteration with locally advanced or recurrent rectal cancer utilising minimally invasive techniques. A total of 22 studies were reviewed, including four case reports describing novel approaches. DISCUSSION: Laparoscopic, robotic and trans-anal total mesenteric excision (TaTME) aided pelvic exenteration methods have recently demonstrated low post-operative morbidity and mortality trends. Minimally invasive methods also have improved rates of R0 resection in modest cohort studies. Hybrid methods have also been proposed to overcome observed technical difficulties such as the narrow male pelvis and obese habitus. There is still limited data beyond case report and small cohort studies on challenging patient groups such as those with recurrent rectal cancer or bony involvement, as a consequence of patient selection for these novel approaches. CONCLUSION: International, multicentre studies have provided the best opportunity to explore efficacy of these methods on a larger scale. Further research is required into patient selection, safety and long-term outcomes of these approaches within high volume centres practicing beyond the surgical learning curve.

BACKGROUND: Robotic surgery has gained significant momentum in rectal cancer surgery. Most studies focus on short-term and oncological outcomes, showing similar outcomes to laparoscopic surgery. Increasing survivorship mandates greater emphasis on quality of life and long-term function. OBJECTIVE: This study aimed to compare quality of life and urinary, sexual, and lower GI functions between robotic and laparoscopic rectal surgeries. DATA SOURCES: A systematic search of Medline, PubMed, Embase, Clinical Trials Register, and Cochrane Library-identified articles comparing robotic with laparoscopic rectal resections was performed. MAIN OUTCOME MEASURES: The outcome measures were quality of life and urinary, sexual, and GI functions between robotic and laparoscopic rectal resection patient groups. Where comparable data were available, results were pooled for analysis. RESULTS: The initial search revealed 1777 papers; 101 were reviewed in full, and 14 studies were included for review. Eleven assessed male sexual function; 7 favored robotic surgery, and the remaining studies showed no significant difference. Pooled analysis of 5 studies reporting rates of male sexual dysfunction at 12 months showed significantly lower rates after robotic surgery (OR, 0.51; p = 0.043). Twelve studies compared urinary function. Six favored robotic surgery, but in 2 studies, a difference was seen at 6 months but not sustained at 12 months. Pooled analysis of 4 studies demonstrated significantly better urinary function scores at 12 months after robotic surgery (OR, 0.26; p = 0.016). Quality of life and GI function were equivalent, but very little data exist for these parameters. LIMITATIONS: A small number of studies compare outcomes between these groups; only 2 are randomized. Different scoring systems limit comparisons and pooling of data. CONCLUSIONS: The limited available data suggest that robotic rectal cancer resection improves male sexual and urinary functions when compared with laparoscopy, but there is no difference in quality of life or GI function. Future studies should report all facets of functional outcomes using standardized scoring systems.

BACKGROUND: The prevalence of elderly patients with resectable colorectal peritoneal metastases (CRPM) is increasing. This study aimed to compare short and long-term outcomes of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for CRPM in patients above and below 70 years of age. METHODS: This was a retrospective, 10-year analysis of 90-day major morbidity and mortality, and long-term survival. RESULTS: Thirty-two (21.3%) of 150 consecutive patients who underwent CRS and HIPEC during the study period were aged 70 and older. PCI (P = 0.04), perioperative chemotherapy use (P < 0.01) and organ resections (rectum P = 0.04, diaphragm P = 0.03) were less in the over 70 group. There was no significant differences in major morbidity (P = 0.19) and mortality (P = 0.32). There was also no difference in 5-year overall survival (OS) (≥70: 26% vs. <70: 39%; P = 0.68) and disease-free survival (DFS) (≥70: 25% vs. <70: 14%; P = 0.22). Age above 70 was not independently associated with worse OS (HR 1.55, P = 0.20) and DFS (HR 1.07, P = 0.81). CONCLUSION: The surgical management of CRPM appears safe and feasible in this elderly population. Appropriate selection of elderly patients for such radical intervention is reinforced by the comparable survival with those under 70.

AIM: To explore the feasibility and safety of robotic beyond total mesorectal excision (TME) surgery for primary and recurrent pelvic malignancy. METHODS: Patients undergoing robotic beyond TME resections for primary or recurrent pelvic malignancy between July 2015 and July 2021 in a public quaternary and a private tertiary centre were included. Demographic and clinical data were recorded and outcomes analysed. RESULTS: Twenty-four patients (50% males) were included, with a median age of 58 (45-70.8) years, and a BMI of 26 (24.3-28.1) kg/m2 . Indication for surgery was rectal adenocarcinoma in nineteen, leiomyosarcoma in two, anal squamous cell carcinoma in one and combined rectal and prostatic adenocarcinoma in two patients. All patients required resection of at least one adjacent pelvic organ including genitourinary structures (n = 23), internal iliac vessels (n = 3) and/or bone (n = 2). Eleven patients had a restorative procedure. Of the 13 nonrestorative cases, nine needed perineal reconstruction with a flap. There was one conversion due to bleeding. The mean operating time was 370 (285-424) min, and the median blood loss was 400 (200-2,000) ml. The median length of stay was 16 (9.3-23.8) days. Fourteen patients (58.3%) had postoperative complications; eight of them (33.3%) were Clavien-Dindo III or more complication. Twenty-three (95.8%) patients had an R0 resection. During a median follow-up of 10 (7-23.5) months, five patients (20.8%) had systemic recurrences. No local recurrences were identified during the study period. CONCLUSION: Implementation of robotic beyond TME surgery for primary and recurrent pelvic malignancy is feasible within a highly specialised setting.

BACKGROUND: Cytoreductive surgery (CRS) with or without hyperthermic intraperitoneal chemotherapy (HIPEC) is a well-recognised treatment option for the management of colorectal peritoneal metastases (CRPM). However, incorporating the routine use of neoadjuvant chemotherapy (NAC) into this management plan is controversial. METHODS: A systematic review and meta-analysis were conducted to evaluate the impact of neoadjuvant chemotherapy on perioperative morbidity and mortality, and long-term survival of patients with CRPM undergoing CRS and HIPEC. RESULTS: Twelve studies met the inclusion criteria (n = 2,463 patients). Ten were retrospective cohort, one was prospective cohort, and one was a prospective randomised by design. Patients who received NAC followed by CRS and HIPEC experienced no difference in major perioperative morbidity and mortality compared with patients who underwent surgery first (SF). There was no difference in overall survival at 3 years, but at 5 years NAC patients had superior survival (relative risk [RR] 1.31; 95% confidence interval [CI] 1.11-1.54, P < 0.001). There were no differences in 1- and 3-year, disease-free survival (DFS) between groups. Study heterogeneity was generally high across all outcome measures. CONCLUSIONS: Patients who received neoadjuvant chemotherapy did not experience any increase in perioperative morbidity or mortality. The potential improvement in 5-year overall survival in patients receiving NAC is based on limited confidence due to several limitations in the data, but not sufficiently enough to curtail its use. The practice of NAC in this setting will remain heterogeneous and guided by retrospective evidence until prospective, randomised data are reported.

BACKGROUND: Pseudomyxoma peritonei (PMP) is a rare clinical entity, commonly derived from a mucin-producing tumour of the appendix. International consensus is unclear on the role of positron emission tomography (PET) in preoperative staging. This study aimed to assess the ability of preoperative PET in predicting the histological grade of PMP. METHODS: All patients scheduled for cytoreductive surgery (CRS) +/- hyperthermic intraperitoneal chemotherapy (HIPEC) for PMP who underwent preoperative PET at a single centre between June 2007 and June 2020 were included. A nuclear medicine physician, blinded to patient outcomes, retrospectively reviewed imaging studies to assess for maximum tumour standardised uptake value (SUV) to mean liver SUV ratio (SUVTLR) and maximum porta hepatis SUV to mean liver SUV ratio (SUVPLR). RESULTS: Between April 2007 and December 2020, a total of 204 patients underwent surgical intervention for PMP. Of these, 124 (60.8%) met the inclusion criteria. Median peritoneal carcinomatosis index for the entire cohort was 9 and complete cytoreduction (CC0/1) was achieved in 109 (88%) patients. Patients with high-grade PMP were more likely to have diffuse peritoneal disease (p < 0.001) and higher SUVTLR (p<0.001). The area under the ROC curve (AUC) of SUVTLR in predicting high-grade pathology was 71% (p = 0.003). Patients with a SUVTLR ≤ 0.78 had improved disease-free survival (p = 0.042). CONCLUSION: Preoperative PET showed positive correlation with high-grade PMP and acceptable sensitivity and specificity as a diagnostic tool. PET should be considered a useful adjunct to standard imaging for predicting histological grade in the staging of patients with PMP.

AIM: This study aims to compare the short-term outcomes of robotic complete mesocolic excision (RCME) versus conventional robotic right colectomy (RRC) for right-sided colon cancer. METHODS: Consecutive patients who underwent robotic surgery for right-sided colon cancer in a public quaternary and a private tertiary healthcare centre between November 2018 and June 2020 were included. Clinical, perioperative and histopathological variables were collected and analysed. RESULTS: Fifty-one patients were included; 25 (49%) of them had an RCME. The groups were evenly distributed in terms of demographic characteristics and tumour location. Operative time was similar between both groups, and no patients required conversion to open surgery. There were no differences in overall complications (16% in RCME vs. 26.9% in RRC; p = 0.499) or their profile between groups. There were no anastomotic leaks recorded, and the reoperation rates were similar (0% for RCME versus 3.8% for RRC; p = 1). In addition, the median length of hospital stay was similar in between the RCME and the RRC groups (4 [4-6] days versus 5 [3-8.5] days, respectively; p = 0.891). Whilst there were no differences in the TNM staging, the mean number of lymph nodes harvested with RCME was 37.7 (±12.9) compared to 21.8 (±7.5) with RCC (p < 0.001). CONCLUSION: In our series, RCME was associated with a higher lymph node harvest and a similar morbidity profile compared to RCC. Further studies are required to validate these results and provide long-term oncologic outcomes.

Rectal bleeding occurs in about 40% of pregnant women, and is predominantly attributed to benign perianal pathology (haemorrhoids or anal fissures). More sinister causes of rectal bleeding may be heralded by key red flag clinical and biochemical features. These features should be evaluated in all women with rectal bleeding. Imaging investigations or flexible sigmoidoscopy may be warranted. The latter can be performed safely by experienced operators in pregnant women. Women with evidence of haemodynamic compromise, elevated inflammatory markers, significant anaemia, signs of intestinal obstruction or compromise to the fetus should be evaluated urgently. Providers must be mindful of the changes in normal ranges for common haematological and biochemical parameters in pregnancy compared with the non-pregnant state. Faecal calprotectin is an established tool for identification of intestinal inflammation and is valid in pregnancy. An elevated faecal calprotectin level (≥ 50 µg/g) signifies a need for further diagnostic evaluation. Inflammatory bowel disease may present initially, or with worsening disease activity, in pregnancy. Expedient diagnosis with the use of faecal calprotectin, sigmoidoscopy with or without intestinal ultrasound, exclusion of alternative or compounding infective aetiologies, and institution of appropriate therapy are critical. Medical therapies for management of inflammatory bowel disease can be safely instituted in pregnancy. Colorectal cancer incidence is increasing in younger age groups, but fortunately remains rare. When diagnosed in pregnancy, colorectal cancer can be successfully and safely managed with a collaborative multidisciplinary team approach. Early diagnosis is key to optimising outcomes.

PURPOSE: Pelvic exenteration (PE) for locally advanced pelvic malignancy is well established, though high rates of morbidity and mortality exist. Such a complication profile has often deterred the surgical community from offering exenteration in combination with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). We aimed to evaluate the perioperative outcomes following pelvic exenteration when combined with CRS and HIPEC for peritoneal surface malignancy (PSM) in a tertiary referral centre. METHODS: A review of a prospectively maintained PSM database from June 2015 to December 2020 at a tertiary referral institution was performed. Patients who underwent CRS, PE, and HIPEC were matched with patients who underwent PE alone. Primary endpoints were perioperative morbidity and mortality. RESULTS: From June 2015 to December 2020, 20 patients required PE as part of their CRS and HIPEC for PSM. The majority of patients were female (n = 16, 80%) with a median age of 52 (range 21-70). Colorectal cancer was the predominant pathology (n = 12, 60%). Median PCI was 11.5 (range 3-39). CC0 and R0 resections were achieved in all patients. CRS, PE, and HIPEC and PE-alone groups were well matched for clinicopathological variables. There was no difference in perioperative major morbidity (HIPEC: 30% vs PE: 15% p = 0.256) and mortality (HIPEC: 0 vs PE: 5% p = 0.311) between groups. Median follow-up was 17.5 months (range 7-68). Eight patients (40%) died from disease-related issues during the study period. CONCLUSION: An aggressive surgical strategy with complete resection is feasible and safe in select patients with complex PSM involving the pelvis.

BACKGROUND: Although currently limited, the requirement for colorectal trainees to attain skills in robotic surgery is likely to increase due to further utilization of robotic platforms globally. The aim of the study is to describe the training programme utilized and assess outcomes of fellowship training in robotic colorectal surgery. METHODS: A structured robotic training programme was generated across a tertiary hospital setting. Review of four prospectively maintained fellow operative logbooks was performed to assess caseload and skill acquisition. Operative and patient-related outcomes were compared with consultant trainer performed cases. Data were analysed using R with a P < 0.05 considered significant. RESULTS: The structured robotic training scheme is a two-tiered system over a 12-month period. The trainer-directed pathway comprised of a robotic console safety course followed by cart-side assisting, a wet lab animal course, dual-console accreditation training course and onsite proctoring, prior to becoming an independent console surgeon. Over 2 years, 265 robotic (n = 143 primary/component surgeon) cases were undertaken with fellows A, B, C and D involved in 63, 77, 75 and 50 robotic colorectal cases, respectively. Individual learning curves revealed independent procedure competency at cases 11, 14, 15 and 12, respectively, for robotic anterior resection. There was no significant difference observed in operative time (P = 0.39), blood loss (P = 0.41), lymph node harvest (P = 0.35), conversion rates (2% versus 4%), anastomotic leaks (1% versus 3%) and R0 resection rates (100% versus 98% colonic, 96% versus 96% rectal, P = 0.48) between surgical fellows and consultant trainers. Clavien-Dindo(III-IV) complications were similar (10% versus 6%,P = 0.25) with no mortalities encountered. CONCLUSION: It is feasible and safe to train fellows in robotic colorectal surgery without compromise of operative- and patient-related outcomes.
