RESUMO
Splenic vein aneurysm (SVA) rupture is a rare clinical entity, with few case reports detailing its occurrence during pregnancy. We describe a case of a SVA rupture and present a systematic review of the literature in relation to splenic vein rupture, with or without aneurysm. Our case was of a 30-year-old woman, Para 4 at 37 weeks' gestation who presented with significant abdominal pain and subsequent maternal collapse. Massive intra-abdominal hemorrhage was identified, with splenic vessel rupture suspected. A splenectomy and partial pancreatectomy were performed along with massive blood product transfusion. There was both maternal and fetal survival with no long-term sequelae at follow-up. Histological examination of the spleen and its vessels noted a SVA rupture. In a subsequent systematic review of the literature, we identified 10 cases of splenic vein rupture with only two previously documented cases of SVA rupture in pregnancy. Maternal and fetal survival has only been reported in two cases of splenic vein rupture, with ours being a third.
RESUMO
BACKGROUND: Enhanced recovery after surgery (ERAS) programmes are evidence-based care improvement processes for surgical patients, which are designed to decrease the impact the anticipated negative physiological cascades following surgery. AIM: To perform a systematic review and meta-analysis of randomised clinical trials (RCTs) to evaluate the impact of ERAS protocols on outcomes following bariatric surgery compared to standard care (SC). METHODS: A systematic review was performed in accordance with PRISMA guidelines. Meta-analysis was performed using Review Manager version 5.4 RESULTS: Six RCTs including 740 patients were included. The mean age was 40.2 years, and mean body mass index was 44.1 kg/m2. Overall, 54.1% underwent Roux-en-Y gastric bypass surgery (400/740) and 45.9% sleeve gastrectomy (340/700). Overall, patients randomised to ERAS programmes had a significant reduction in nausea and vomiting (odds ratio (OR): 0.42, 95% confidence interval (CI): 0.19-0.95, P = 0.040), intraoperative time (mean difference (MD): 5.40, 95% CI: 3.05-7.77, P < 0.001), time to mobilisation (MD: - 7.78, 95% CI: - 5.46 to - 2.10, P < 0.001), intensive care unit stay (ICUS) (MD: 0.70, 95% CI: 0.13-1.27, P = 0.020), total hospital stay (THS) (MD: - 0.42, 95% CI: - 0.69 to - 0.16, P = 0.002), and functional hospital stay (FHS) (MD: - 0.60, 95% CI: - 0.98 to - 0.22, P = 0.002) compared to those who received SC. CONCLUSION: ERAS programmes reduce postoperative nausea and vomiting, intraoperative time, time to mobilisation, ICUS, THS, and FHS compared to those who received SC. Accordingly, ERAS should be implemented, where feasible, for patients indicated to undergo bariatric surgery.

INTRODUCTION: There is uncertainty regarding the optimal mesh fixation techniques for laparoscopic ventral and incisional hernia repair. AIM: To perform a systematic review and network meta-analysis of randomised control trials (RCTs) to investigate the advantages and disadvantages associated with absorbable tacks, non-absorbable tacks, non-absorbable sutures, non-absorbable staples, absorbable synthetic glue, absorbable sutures and non-absorbable tacks, and non-absorbable sutures and non-absorbable tacks. METHODS: A systematic review was performed as per PRISMA-NMA guidelines. Odds ratios (ORs) and mean differences (MDs) were extracted to compare the efficacy of the surgical approaches. RESULTS: Nine RCTs were included with 707 patients. Short-term pain was significantly reduced in non-absorbable staples (MD; -1.56, confidence interval (CI); -2.93 to -0.19) and non-absorbable sutures (MD; -1.00, CI; -1.60 to -0.40) relative to absorbable tacks. Recurrence, length of stay, operative time, conversion to open surgery, seroma and haematoma formation were unaffected by mesh fixation technique. CONCLUSION: Short-term post-operative pain maybe reduced by the use of non-absorbable sutures and non-absorbable staples. There is clinical equipoise between each modality in relation to recurrence, length of stay, and operative time.

PURPOSE: The purpose of this paper is to report on changes in overall survival, progression-free survival, and complete cytoreduction rates in the 5-year period after the implementation of a multidisciplinary surgical team (MDT). METHODS: Two cohorts were used. Cohort A was a retrospectively collated cohort from 2006 to 2015. Cohort B was a prospectively collated cohort of patients from January 2017 to September 2021. RESULTS: This study included 146 patients in cohort A (2006-2015) and 174 patients in cohort B (2017-2021) with FIGO stage III/IV ovarian cancer. Median follow-up in cohort A was 60 months and 48 months in cohort B. The rate of primary cytoreductive surgery increased from 38% (55/146) in cohort A to 46.5% (81/174) in cohort B. Complete macroscopic resection increased from 58.9% (86/146) in cohort A to 78.7% (137/174) in cohort B (p < 0.001). At 3 years, 75% (109/144) patients had disease progression in cohort A compared with 48.8% (85/174) in cohort B (log-rank, p < 0.001). Also at 3 years, 64.5% (93/144) of patients had died in cohort A compared with 24% (42/174) of cohort B (log-rank, p < 0.001). Cox multivariate analysis demonstrated that MDT input, residual disease, and age were independent predictors of overall (hazard ratio [HR] 0.29, 95% confidence interval [CI] 0.203-0.437, p < 0.001) and progression-free survival (HR 0.31, 95% CI 0.21-0.43, p < 0.001). Major morbidity remained stable throughout both study periods (2006-2021). CONCLUSIONS: Our data demonstrate that the implementation of multidisciplinary-team, intraoperative approach allowed for a change in surgical philosophy and has resulted in a significant improvement in overall survival, progression-free survival, and complete resection rates.

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
Summary: Phaeochromocytoma, a rare neuroendocrine tumour of chromaffin cell origin, is characterised by catecholamine excess. Clinical presentation ranges from asymptomatic disease to life-threatening multiorgan dysfunction. Catecholamine-induced cardiomyopathy is a dreaded complication with high lethality. While there is lack of evidence-based guidelines for use of veno-arterial extracorporeal membrane oxygenation (V-A ECMO) in the management of this condition, limited to case reports and small case series, V-A ECMO has been reported as 'bridge to recovery' therapy, providing circulatory support in the initial period of stabilisation prior to surgery. We report on two patients presenting with catecholamine-induced cardiomyopathy and circulatory collapse who were successfully treated with V-A ECMO for 5 and 6 days, respectively, providing initial haemodynamic support. After stabilisation and introduction of alpha-blockade, both cases had favourable outcomes, with successful laparoscopic adrenalectomies on days 62 and 83 of admission, respectively. Our case reports provide further support for the use of V-A ECMO in the treatment of such gravely ill patients. Learning points: Phaeochromocytoma should be considered in the diagnosis of patients presenting with acute cardiomyopathy. Management of catecholamine-induced cardiomyopathy is complex and requires multidisciplinary specialist input. Pre-operative management of phaeochromocytoma involves alpha-blockade; however, haemodynamic instability in the setting of cardiogenic shock can preclude alpha-blockade use. Veno-arterial extracorporeal membrane oxygenation is a life-saving intervention which may be considered in cases of acute catecholamine-induced cardiomyopathy and cardiogenic shock in order to provide the required haemodynamic support in the initial phase of treatment, enabling the administration of traditional pharmacological agents, including alpha-blockade.
RESUMO
Introduction: Fluorescence guided surgery for the identification of colorectal liver metastases (CRLM) can be better with low specificity and antecedent dosing impracticalities limiting indocyanine green (ICG) usefulness currently. We investigated the application of artificial intelligence methods (AIM) to demonstrate and characterise CLRMs based on dynamic signalling immediately following intraoperative ICG administration. Methods: Twenty-five patients with liver surface lesions (24 CRLM and 1 benign cyst) undergoing open/laparoscopic/robotic procedures were studied. ICG (0.05 mg/kg) was administered with near-infrared recording of fluorescence perfusion. User-selected region-of-interest (ROI) perfusion profiles were generated, milestones relating to ICG inflow/outflow extracted and used to train a machine learning (ML) classifier. 2D heatmaps were constructed in a subset using AIM to depict whole screen imaging based on dynamic tissue-ICG interaction. Fluorescence appearances were also assessed microscopically (using H&E and fresh-frozen preparations) to provide tissue-level explainability of such methods. Results: The ML algorithm correctly classified 97.2 % of CRLM ROIs (n = 132) and all benign lesion ROIs (n = 6) within 90-s of ICG administration following initial mathematical curve analysis identifying ICG inflow/outflow differentials between healthy liver and CRLMs. Time-fluorescence plots extracted for each pixel in 10 lesions enabled creation of 2D characterising heatmaps using flow parameters and through unsupervised ML. Microscopy confirmed statistically less CLRM fluorescence vs adjacent liver (mean ± std deviation signal/area 2.46 ± 9.56 vs 507.43 ± 160.82 respectively p < 0.001) with H&E diminishing ICG signal (n = 4). Conclusion: ML accurately identifies CRLMs from surrounding liver tissue enabling representative 2D mapping of such lesions from their fluorescence perfusion patterns using AIM. This may assist in reducing positive margin rates at metastatectomy and in identifying unexpected/occult malignancies.
RESUMO
INTRODUCTION: Indocyanine green (ICG) quantification and assessment by machine learning (ML) could discriminate tissue types through perfusion characterisation, including delineation of malignancy. Here, we detail the important challenges overcome before effective clinical validation of such capability in a prospective patient series of quantitative fluorescence angiograms regarding primary and secondary colorectal neoplasia. METHODS: ICG perfusion videos from 50 patients (37 with benign (13) and malignant (24) rectal tumours and 13 with colorectal liver metastases) of between 2- and 15-min duration following intravenously administered ICG were formally studied (clinicaltrials.gov: NCT04220242). Video quality with respect to interpretative ML reliability was studied observing practical, technical and technological aspects of fluorescence signal acquisition. Investigated parameters included ICG dosing and administration, distance-intensity fluorescent signal variation, tissue and camera movement (including real-time camera tracking) as well as sampling issues with user-selected digital tissue biopsy. Attenuating strategies for the identified problems were developed, applied and evaluated. ML methods to classify extracted data, including datasets with interrupted time-series lengths with inference simulated data were also evaluated. RESULTS: Definable, remediable challenges arose across both rectal and liver cohorts. Varying ICG dose by tissue type was identified as an important feature of real-time fluorescence quantification. Multi-region sampling within a lesion mitigated representation issues whilst distance-intensity relationships, as well as movement-instability issues, were demonstrated and ameliorated with post-processing techniques including normalisation and smoothing of extracted time-fluorescence curves. ML methods (automated feature extraction and classification) enabled ML algorithms glean excellent pathological categorisation results (AUC-ROC > 0.9, 37 rectal lesions) with imputation proving a robust method of compensation for interrupted time-series data with duration discrepancies. CONCLUSION: Purposeful clinical and data-processing protocols enable powerful pathological characterisation with existing clinical systems. Video analysis as shown can inform iterative and definitive clinical validation studies on how to close the translation gap between research applications and real-world, real-time clinical utility.

INTRODUCTION: Textbook outcomes (TBO) are composite measures of care which may be superior in assessing quality compared to traditional methods. We aim to define TBO which are specific to surgical resection of colorectal liver metastases, and investigate their impact on survival. METHODS: Single center analysis of all liver resections performed at our center from 2009 to 2020. A Cox model was used to identify perioperative outcomes which impacted on overall survival. These were retained with important postoperative outcomes to form a "TBO." The impact of a TBO on overall survival was investigated using Kaplan-Meier curve analysis. RESULTS: TBO was achieved in 72.2% (197/273) of resections. Major morbidity (Clavien-Dindo ≥3) at 19.4% was the major limiting factor in not achieving a TBO. TBO was associated with improved 3-year (77% vs. 55%), 5-year (60.7% vs. 42.5%), and median (93 vs. 44 months) overall survival (log-rank test, p = 0.006). Multivariable analysis revealed age >65 years, American Society of Anaesthesiologists Grade III-IV, and resection of >2 segments as factors predictive of not achieving a TBO. CONCLUSION: TBO is a useful composite measure in surgery for colorectal liver metastases. It can highlight areas which may be targeted for quality improvement and be useful as a tool to examine variation between centers. Achieving a TBO is associated with a significant improvement in survival.

The uptake of robotic surgery is rapidly increasing worldwide across surgical specialties. However, there is currently a much higher use of robotic surgery in the United States of America (USA) compared to the United Kingdom (UK) and Ireland. Reduced exposure to robotic surgery in training may lead to longer learning curves and worse patient outcomes. We aimed to identify whether any difference exists in exposure to robotic surgery during general surgical training between trainees in the USA, UK and Ireland. Over a 15-week period from September 2021, a survey was distributed through the professional networks of the research team. Participants were USA, UK or Irish trainees who were part of a formal general surgical training curriculum. 116 survey responses were received. US trainees (n = 34) had all had robotic simulator experience, compared to only 37.93% of UK (n = 58) and 75.00% of Irish (n = 24) trainees (p < 0.00001). 91.18% of US trainees had performed 15 or more cases as the console surgeon, compared to only 3.44% of UK and 16.67% of Irish trainees (p < 0.00001). Fifty UK trainees (86.21%) and 22 Irish trainees (91.67%) compared to 12 US trainees (35.29%) do not think they have had adequate robotics training (p < 0.00001). Surgical trainees in the USA have had significantly more exposure to training in robotic surgery than their UK and Irish counterparts.

INTRODUCTION: There is resurging interest in the importance of effective, nuanced insufflation and personalised pneumoperitoneal pressure-management during laparoscopy. Here, we present user-evaluation data from a regulated, prospective, multispecialty study of a new insufflator (EVA-15, Palliare, Galway, Ireland) which provides high-frequency pressure-sensing, built-in smoke evacuation with pedal activation and highly responsive, high-flow gas provision. METHODS: With institutional ethics and regulatory body approval, a non-randomised, prospective clinical investigation was performed on 30 subjects undergoing laparoscopic surgery using an EVA-15 device. Cases were selected from a variety of specialties on a near-consecutive basis without specific exclusion criteria. Users (both surgeons and operating room nurses) completed a survey at case completion to capture ordinal categorical data on a 5-point Likert agreement scale (1 - Strongly disagree to 5 - Strongly agree) concerning (i) Settings and Setup Evaluations, (ii) Alarms and Displays Evaluations, (iii) Short Instruction Guide, and (iv) Insufflator Performance along with any additional feedback. RESULTS: Operations on 30 patients (mean age 54 y, 15 males) were studied with a questionnaire completed by operating room teams after individual consent. The procedures included general (n=13), upper (n=3) and lower (n=6) gastrointestinal surgery, bariatric (n=3), hepatobiliary (n=2) urology (n=2, both robotic prostatectomy) and gynaecology (n=1) operations. In all cases, the laparoscopic component was completed capably with the use of the EVA-15 device. The insufflator evaluation score across all categories was a median of 4, demonstrating satisfactory use and performance in all regards. CONCLUSION: The EVA-15 is a smart insufflator system that is capable of satisfactory performance across a spectrum of cases among different specialties.

BACKGROUND: Ursodeoxycholic acid (UDCA) is a bile acid that has been shown to reduce the formation of gallstones after significant weight loss. OBJECTIVE: This study aimed to evaluate the impact of UDCA on the incidence of gallstones after bariatric surgery. SETTINGS: An electronic search of PubMed (Medline), Cochrane Central Register of Controlled Studies (CENTRAL), Scopus (Elsevier) databases, EMBASE, CINAHL, Clinicaltrials.gov, and Web of Science. METHODS: A meta-analysis of randomized control trials was performed. The primary outcome was the incidence of gallstones after bariatric surgery. Secondary outcomes included type of operation and time interval to and characteristics associated with gallstone formation. RESULTS: Ten randomized control trials including 2583 patients were included, 1772 patients (68.6%) receiving UDCA and 811 (31.4%) receiving placebo. There was a significant reduction in gallstone formation in patients who received UDCA postoperatively (risk ratio [RR] .36, 95% confidence interval [CI] .22-.41, P < .00001). The overall prevalence of gallstone formation was 24.7% in the control group compared to 7.3% in the UDCA group. A dose of ≤600 mg/day had a significantly reduced risk of gallstone formation compared to the placebo group (risk ratio .35; 95% CI .24-.53; P < .001). The risk reduction was not significant for the higher dose (>600 mg/day) group (risk ratio .30; 95% CI, .09-1.01, P = .05). CONCLUSIONS: UDCA significantly reduces the risk of both asymptomatic and symptomatic gallstones after bariatric surgery. A dose of 600 mg/day is associated with improved compliance and better outcomes regardless of type of surgery. UDCA should be considered part of a standard postoperative care bundle after bariatric surgery.

In recent years, the management of colorectal liver metastases (CRLM) has evolved significantly. Laparoscopic liver resection is increasingly being performed, despite a lack of major randomized controlled trial evidence or widespread international consensus. The objective of this review was to compare the short- and long-term outcomes following open and laparoscopic CRLM resection. A systematic review of comparative matched population studies was performed. Evaluated endpoints included surgical outcomes and survival outcomes. Twelve studies were included in this review, reporting on 3095 patients. R0 (negative margins) rates were higher in the laparoscopic CRLM group (89.3% versus 86.9%). In addition, laparoscopic resection was associated with less blood loss (486 mls versus 648 mls, p ≤ 0.0001*) and reduced blood transfusion rates (6.7% vs. 12.2%, OR 2.13, 95% CI 1.08-4.19, p = 0.03*). Major complication rates were higher in the open CRLM group (12.5% vs. 8.1%, OR 1.74, 95% CI 1.30-2.33, p = 0.03*), as was overall hospital length of stay (median 7 versus 5.5 days, p = 0.001*). Perioperative mortality was similar between both groups, and there was no significance in 5-year overall survival for open or laparoscopic CRLM resection groups (58% and 61% respectively). Laparoscopic CRLM resection is associated with less blood loss, lower transfusion rates, major complications, and overall hospital length of stay with comparable oncological outcome.

INTRODUCTION: We assessed management of patients with de novo metastatic rectal cancer, referred for radiotherapy to the rectum, who were candidates for short-course radiotherapy (SCRT) and chemotherapy, followed by resection of all disease. We assessed surgical outcomes, overall survival (OS) and progression-free survival (PFS). METHODS: Retrospective review of patients meeting criteria: (i) treatment with SCRT to rectum; (ii) locally advanced primary rectal cancer; and (iii) resectable distant metastases at diagnosis. Data were collected from charts, correspondence and electronic patient records. OS and PFS were calculated using the Kaplan-Meier method. RESULTS: Between 2016 and 2020, 48 patients with stage IV rectal cancer at diagnosis were treated with SCRT. Only 15 patients (31%) had resectable metastatic disease and were intended for SCRT (25 Gy/5#), then chemotherapy, followed by resection of all sites of disease and are included in our study. 12 of the 15 surgical candidates (80%) had rectal surgery as planned, and 11 of the 15 (73%) had resection of the rectal primary and all metastatic disease. One patient had a pathological complete response (pCR), and 50% of surgical patients had a Mandard TRG of 1 or 2. Median PFS and OS for the 15 surgical candidates were 12.6 and 25.2 months, respectively, with a median FU of 21.2 months. CONCLUSION: For this cohort of patients, our treatment paradigm is pragmatic and results in excellent pathological response. However, the effectiveness of this approach should be the subject of future prospective studies.

SUMMARY: Phaeochromocytoma is a rare catecholamine-producing tumour. We present the case of phaeochromocytoma in a young man with a background history of a double-lung transplant for cystic fibrosis (CF). Clinical case: A 25-year-old man, with a background history of CF, CF-related diabetes (CFRD) and a double-lung transplant in 2012 was presented to the emergency department with crampy abdominal pain, nausea and vomiting. He was diagnosed with distal intestinal obstructions syndrome (DIOS). Contrast-enhanced CT imaging of the abdomen and pelvis showed a 3.4 cm right adrenal lesion. This was confirmed by a subsequent MRI of adrenal glands that demonstrated moderate FDG uptake, suggestive of a diagnosis of phaeochromocytoma. The patient was noted to be hypertensive with a blood pressure averaging 170/90 mm/Hg despite treatment with three different anti-hypertensive medications - amlodipine, telmisartan and doxazosin. He had hypertension for the last 3 years and had noted increasingly frequent sweating episodes recently, without palpitations or headache. Laboratory analysis showed elevated plasma normetanephrines (NMN) of 3167 pmol/L (182-867) as well as elevated metanephrines (MN) of 793 pmol/L (61-377) and a high 3-MT of 257 pmol/L (<185). Once cathecholamine excess was identified biochemically, we proceeded to functional imaging to further investigate. MIBG scan showed a mild increase in the uptake of tracer to the right adrenal gland compared to the left. The case was discussed at a multidisciplinary (MDT) meeting at which the diagnosis of phaeochromocytoma was made. Following a challenging period of 4 weeks to control the patient's blood pressure with an alpha-blocker and beta-blocker, the patient had an elective right adrenalectomy, with normalisation of his blood pressure post-surgery. The histopathology of the excised adrenal gland was consistent with a 3 cm phaeochromocytoma with no adverse features associated with malignant potential. LEARNING POINTS: Five to ten per cent of patients have a secondary cause for hypertension. Phaeochromocytomas are rare tumours, originating in chromaffin cells and they represent 0.1-1.0% of all secondary hypertension cases. Secondary causes should be investigated in cases where: Patient is presenting <20 years of age or >50 years of age, There is refractory hypertension, or There is serious end-organ damage present. Patients may present with the triad of headache, sweating and palpitations or more vague, non-specific symptoms. Patients with suspected phaeochromocytoma should have 24-h urinary catecholamines measured and if available, plasma metanephrines measured. Those with abnormal biochemical tests should be further investigated with imaging to locate the tumour. Medical treatment involves alpha- and beta-blockade for at least 2 to 3 weeks before surgery as well as rehydration. There is a possibility of relapse so high-risk patients require life-long follow-up.
RESUMO
We report a case of a 16-year-old adolescent male born with univentricular congenital cyanotic heart disease (CCHD) who was diagnosed with an incidental paraganglioma while awaiting a cardiac transplant. The coexistence of paraganglioma and univentricular CCHD is very rare, with no previous cases described in the literature of a patient concurrently requiring a cardiac transplant. The complex physiology associated with a common atrium, common ventricle, aortopulmonary lung perfusion and a hypoplastic left lung rendered our patient extremely vulnerable to catecholamine-mediated effects of preload, contractility and afterload. The interactions and interdependence between these systems provided unique difficulties for perioperative management with serious implications for prospective cardiac transplant.

BACKGROUND: Cytoreductive Surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) is increasingly accepted as the optimal management of selected patients with peritoneal malignancy. There is limited published evidence on outcomes in older patients treated by this complex therapeutic strategy. METHODS: A retrospective review of a prospective database of all patients who underwent CRS with HIPEC in a single institution over seven years. A comparative analysis of outcomes in patients under 65 undergoing CRS and HIPEC with patients ≥65 years was performed. The key endpoints were morbidity, mortality, reintervention rate and length of stay in the high dependency/intensive care (HDU/ICU) units. RESULTS: Overall, 245 patients underwent CRS and HIPEC during the study period, with 76/245 (31%) ≥65 years at the time of intervention. Tumour burden measured by the peritoneal carcinomatosis index (PCI) score was a median of 11 for both groups. Median length of hospital stay in the ≥65-year-old group was 14.5 days versus 13 days in the <65-year-old group (∗p = 0.01). Patients aged ≥65-years spent a median of one more day in the critical care unit ∗(p = 0.001). Significant morbidity (Clavien-Dindo ≥ Grade IIIa) was higher in the ≥65-year than the <65-year group (18.4% versus 11.2%). There were no perioperative deaths in the ≥65-year group. CONCLUSION: This study demonstrates higher perioperative major morbidity in ≥65-year group, but with low mortality in patients undergoing CRS/HIPEC for disseminated intraperitoneal malignancy. This increased morbidity does not translate into higher rates of re-interventions and highlights the importance of optimal patient selection.

PURPOSE: Synchronous liver resection, cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for colorectal liver (CRLM) and peritoneal metastases (CRPM) has traditionally been contraindicated. However, latest practice promotes specialist, multidisciplinary-led consideration for select patients. This study aimed to evaluate the perioperative and oncological outcomes of synchronous resection in the management of CRLM and CRPM from two tertiary referral centres. METHOD: This bi-institutional, retrospective, cohort study included patients undergoing simultaneous liver resection, CRS and HIPEC for metastatic colorectal cancer from 2013 to 2020. Patients treated with ablative liver techniques, staged operative approaches and extra abdominal disease were excluded. Overall survival (OS) and disease-free survival (DFS) rates were assessed. Univariate and multivariate analyses identified variables associated with survival and major morbidity (Clavien-Dindo grade III/IV). RESULTS: Twenty-three patients were included. The median peritoneal carcinomatosis index (PCI) was 9 (range 0-22). There were two major liver resections and 21 minor resections. CC-0 resections were achieved in all patients. Major morbidity occurred in 7 patients. There were no deaths at 90 days. PCI was independently associated with morbidity (p = 0.04). PCI >10 (p = 0.069), major morbidity (p = 0.083) and presence of KRAS mutation (p = 0.052) approached significance for poor OS. Median follow up was 21 months (4-54 months). Median OS was 37 months, 3-year survival 54%, and median DFS 18 months. CONCLUSION: Synchronous liver resection, cytoreductive surgery and HIPEC is feasible in selected patients with low-volume CRPM and CRLM. Increasing PCI is associated with postoperative major morbidity, and should be considered during operative planning.

BACKGROUND: Surgical resection remains the cornerstone of ovarian cancer management. In 2017, the authors implemented a multi-disciplinary surgical team comprising gynecologic oncologists as well as colorectal, hepatobiliary, and upper gastrointestinal (GI) surgeons to increase gross macroscopic resection rates. This report aims to describe changes in complete cytoreduction rates and morbidity after the implementation of a multi-disciplinary surgical team comprising gynecologic oncologists as well as colorectal, hepatobiliary, and upper GI surgeons in a tertiary gynecologic oncology unit. METHODS: The study used two cohorts. Cohort A was a retrospectively collated cohort from 2006 to 2015. Cohort B was a prospectively collated cohort of patients initiated in 2017. A multidisciplinary approach to preoperative medical optimization, intraoperative management, and postoperative care was implemented in 2017. The patients in cohort B with upper abdominal disease were offered primary cytoreduction with or without hyperthermic intraperitoneal chemotherapy (HIPEC). Before 2017, the patients with upper abdominal disease received neoadjuvant chemotherapy (cohort A). RESULTS: This study included 146 patients in cohort A (2006-2015) and 93 patients in cohort B (2017-2019) with stages 3 or 4 ovarian cancer. The overall complete macroscopic resection rate (CC0) increased from 58.9 in cohort A to 67.7% in cohort B. The rate of primary cytoreductive surgery (CRS) increased from 38 (55/146) in cohort A to 42% (39/93) in cohort B. The CC0 rate for the patients who underwent primary CRS increased from 49 in cohort A to 77% in cohort B. Major morbidity remained stable throughout both study periods (2006-2019). CONCLUSIONS: The study data demonstrate that implementation of a multidisciplinary team intraoperative approach and a meticulous approach to preoperative optimization resulted in significantly improved complete resection rates, particularly for women offered primary CRS.
