RESUMO
Complete mesocolic excision (CME) with D3 lymphadenectomy for colon cancer has been shown to improve overall as well as disease-free survival compared to conventional right hemicolectomy. Performing a laparoscopic CME/D3 right hemicolectomy with intracorporeal anastomosis (ICA) can be technically demanding even for experienced operators. Here, we present a systematic, standardized approach to the surgery.

PURPOSE: Minimally invasive surgery for gastrointestinal cancers is rapidly advancing; therefore, surgical education must be changed. This study aimed to examine the feasibility of early initiation of robotic surgery education for surgical residents. METHODS: The ability of staff physicians and residents to handle robotic surgical instruments was assessed using the da Vinci® skills simulator (DVSS). The short-term outcomes of 32 patients with colon cancer who underwent robot-assisted colectomy (RAC) by staff physicians and residents, supervised by a dual console system, between August 2022 and March 2024 were compared. RESULTS: The performances of four basic exercises were assessed after implementation of the DVSS. Residents required less time to complete these exercises and achieved a higher overall score than staff physicians. There were no significant differences in the short-term outcomes, operative time, blood loss, incidence of postoperative complications, and length of the postoperative hospital stay of the two surgeon groups. CONCLUSION: Based on the evaluation involving the DVSS and RAC results, it appears feasible to begin robotic surgery training at an early stage of surgical education using a dual console system.

Over the last few decades, our understanding of the pathophysiology and natural history of sigmoid diverticulitis has greatly improved. This knowledge has challenged many of the traditional principles in the management for diverticulitis, such as routine antibiotic administration in all cases, number-based recommendations for elective surgery, and the necessity for an end colostomy in emergency surgery. This review will cover the breadth of management for sigmoid diverticulitis, covering both uncomplicated and complicated disease as well as elective and emergent disease presentations. New and emerging concepts in management will be highlighted with a particular focus on level-1 data, when available.

Subtotal colectomy is often performed on patients with synchronous colorectal cancer. However, compared with colorectal anastomosis, ileorectal anastomosis with subtotal colectomy is more likely to result in bowel dysfunction. The Deloyers procedure is useful in preserving bowel function in a patient with synchronous colorectal cancer. An 87-year-old man presented with bloody stool. Colonoscopy showed masses in the cecum, transverse colon, rectosigmoid, and rectum above the peritoneal reflection. Computed tomography scan revealed no evidence of regional lymph node swelling and distant metastasis. Therefore, robot-assisted low anterior resection, laparoscopic extended left hemicolectomy, laparoscopic cecal resection, and diverting ileostomy were performed. The patient was discharged from the hospital without complications. There was no recurrence, and the patient did not have complaints such as urgency, fecal incontinence, and excretory dysfunction. Hence, minimally invasive coloproctectomy using the Deloyers procedure can be safe and useful in preserving postoperative bowel function in elderly patients.

Late perforation of the ileum is a rare and potentially life-threatening complication following intestinal resection. We present a unique case of a woman in her 60s with a history of appendiceal carcinoid tumour, who underwent a right hemicolectomy. Positron emission tomography and surveillance CTs showed normal surgical changes and no recurrent malignancy. Three years postoperatively, she presented with severe abdominal pain. CT revealed a perforation along the ileal wall of the ileocolonic anastomosis. She underwent emergent resection and repeat ileocolonic anastomosis. We conclude that the patient had subclinical ischaemia of the anastomosis, which eventually progressed to perforation 3 years later. We discuss a literature review on late small intestinal anastomotic perforations and their associated risk factors. Our case and literature review emphasise the importance of considering delayed anastomotic leak in postoperative patients with a history of intestinal cancer, inflammatory bowel disease, Roux-en-Y enteroenterostomy or side-to-side anastomosis.

Vaginal natural orifice transluminal endoscopic surgery (vNOTES) for colorectal cancer utilizes transvaginal access for bowel mobilization, vascular pedicle ligation, oncological resection, and bowel anastomosis, along with subsequent transvaginal natural orifice specimen extraction (NOSE), reducing or eliminating the need for transabdominal access. In this report, we describe the technique of vNOTES right hemicolectomy for cecal cancer, with intracorporeal anastomosis and transvaginal NOSE, including a step-by-step operative video. The patient was a 59-year-old Chinese female (body mass index 32.0 kg/m2) with a cT3N0M0 3 cm cecal adenocarcinoma. Posterior colpotomy was created with insertion of a dual-ring wound protector. vNOTES D2 right hemicolectomy with a fully stapled intracorporeal anastomosis was performed via a homemade transvaginal glove port, using extra-long rigid instruments. A 10 mm, 30° rigid laparoscope was used for operative visualization through a transumbilical port, without additional percutaneous trocars. Operative difficulties pertained to suboptimal instrument reach, lack of triangulation, and frequent clashing within the restricted access space. Surgical duration was 300 min, with 50 ml of blood loss. There was minimal postoperative pain. Return of bowel function occurred on postoperative day 2, with discharge from hospital on postoperative day 3. The patient resumed normal daily activities and regular diet by 1-week post-surgery. Self-reported cosmetic satisfaction score was excellent. No operative complications were observed at 2 months' follow-up. vNOTES right hemicolectomy with intracorporeal anastomosis is safe and feasible in highly selected colon cancer patients. Operators should be proficient in conventional laparoscopic colectomy and transvaginal NOSE. More experience with the vNOTES technique is required to ascertain best practices.

INTRODUCTION: Ulcerative Colitis (UC) is an Inflammatory Bowel Disease (IBD). Surgery is required in cases of severe acute colitis, massive hemorrhage, toxic megacolon, and perforation; in such cases colectomy and JpouchIleoanal anastomosis (IPAA) are performed. The aim of this study was to evaluate functional outcome, and patient satisfaction and Quality of Life (QoL) after surgery. MATERIAL AND METHODS: Questionnaires were administered to 24 patients with UC undergoing surgery from 2011 to 2022. RESULTS: Mean age at IPAA was 10.8 years. Twenty patients underwent IPAA in 3 operations, 4 patients in 2. All patients underwent laparoscopic surgery. 6 months after surgery mean level of satisfaction was 8.7/10, perception of health status was 7.4. Twenty-three patients (95.8%) recommended IPAA. For 20 patients (83.3%) surgery did not cause delay in education, while 14 patients (58.3%) played sport. The lowest number of evacuations was 9.2 per day, the highest 13.3. Seventeen patients (70.8%) had no incontinence and 15 patients (62.5%) were not affected by pouchitis. After 12 months mean satisfaction level raised up to 9.2/10, perception of health status to 8.5. School absences decreased and no other patients showed any delay in education. Seventeen (70.8%) patients played sports. The number of evacuations decreased: the lowest number was 5.1 per day, the highest 7.5. Twenty patients (83.3%) were continent and 12 (50%) did not use antibiotics. CONCLUSION: Most patients show a good functional outcome in defecation frequency and continence, which has improved through time, number of pouchitis episodes has increased. Patients appear satisfied after surgery.

BACKGROUND: Retrospective research suggests that excision of the affected mesentery can improve outcomes after an ileocoecal resection in Crohn's disease. However, prospective data from randomised controlled trials are scarce. We aimed to compare rates of postoperative recurrence in patients with Crohn's disease who underwent extended mesenteric resection. METHODS: This international, randomised controlled trial was done in six hospitals and tertiary care centres in the Netherlands and Italy. Eligible patients were aged 16 years or older and had Crohn's disease that was previously confirmed by endoscopy in the terminal ileum or ileocolic region (L1 or L3 disease), with an imaging update in the past 3 months (ultrasound, MRI, or CT enterography). Eligible patients were scheduled to undergo primary ileocolic resection with ileocolic anastomosis. Enrolled patients were assigned by use of simple random allocation (1:1) to either extended mesenteric resection (intervention) or conventional mesenteric sparing resection (control). The primary endpoint was endoscopic recurrence 6 months after surgery. Analyses were done in all patients with primary endpoint data, excluding those who had no anastomosis, a postoperative diagnosis other than Crohn's disease, or withdrew consent. This trial was registered with ClinicalTrials.gov, NCT04538638. FINDINGS: Between Feb 19, 2020, and April 24, 2023, we assessed 217 patients for eligibility. 78 patients were excluded due to failure to meet the inclusion criteria or refusal to participate. 139 patients were enrolled and randomly assigned to either extended mesenteric resection (n=71) or mesenteric sparing resection (n=68). All 139 patients underwent surgery. Six patients were excluded after random assignment due to withdrawal of consent (n=2), postoperative diagnosis other than Crohn's disease (n=2) and no anastomosis performed (in case of a stoma; n=2). Two patients were lost to follow-up, and two more patients deviated from the protocol by undergoing investigations other than endoscopy 6 months after. 133 patients were included in the baseline analysis (67 in the extended resection group and 66 in the sparing resection group) of whom 57 (43%) were male. Baseline characteristics were similar between the groups, and median patient age was 36 years (IQR 25-54). 131 patients were analysed for the primary outcome. There was no difference between groups in the rate of endoscopic recurrence at 6 months after surgery (28 [42%] of 66 patients in the extended mesenteric resection group vs 28 [43%] of 65 patients in the mesenteric sparing resection group, relative risk 0·985, 95% CI 0·663-1·464; p=1·0). Five (8%) of 66 patients in the extended mesenteric resection group had anastomotic leakage within the 30 days after surgery, as did one (2%) of 65 in the mesenteric sparing group. Postoperative complications of Clavien-Dindo grade IIIa or higher were reported in seven (11%) patients in the mesenteric resection group and five (8%) in the mesenteric sparing group. INTERPRETATION: Extended mesenteric resection was not superior to conventional resection with regard to endoscopic Crohn's disease recurrence. These data support the guideline-recommended mesenteric sparing approach. FUNDING: Topconsortia voor Kennis en Innovatie-Topsector Life Sciences & Health.

OBJECTIVE: Obtaining surgical informed consent (SIC) is a critical skill most residents are expected to learn "on-the-job." This study sought to quantify the effect of 1 year of clinical experience on performance obtaining SIC in the absence of formal informed consent education. DESIGN: In this case-control cohort study, PGY1 and PGY2 surgical residents in an academic program were surveyed regarding their experiences and confidence in obtaining SIC; then assessed obtaining informed consent for a right hemicolectomy from a standardized patient. SETTING: Single academic general surgery residency program in Buffalo, NY. PARTICIPANTS: Ten PGY1 and eight PGY2 general surgery residents were included in the study, after excluding residents with additional years of training. RESULTS: PGY2 residents had significantly more experience obtaining SIC compared to PGY1 residents (median response: ">50" vs "between 6 and 15," pâ¯=â¯0.001), however there was no difference in self-reported confidence in ability obtaining SIC (mean 3.2/5 in PGY1 vs 3.4/5 in PGY2, pâ¯=â¯0.61), self-reported knowledge of SIC (mean 3.1/5 in PGY1 vs 3.6/5 in PGY2, pâ¯=â¯0.15), performance on a test regarding SIC (mean score 9.0/20, SD 3.9 for PGY1 vs mean score 9.6/20, SD 3.5, tâ¯=â¯0.387, pâ¯=â¯0.739) or performance during a standardized patient interview (mean 11.2/20, SD 2.78 for PGY1 vs mean 11.4/20, SD 1.51 for PGY2, pâ¯=â¯0.87). In the interviews all residents addressed general risks (bleeding/infection), however both groups performed worse in addressing procedure-specific risks including anastomotic leak as risk for hemicolectomy. CONCLUSIONS: A year of clinical training between PGY1 to PGY2 did not improve performance in obtaining surgical informed consent when lacking formal education, despite self-confidence in their ability. A curriculum covering the content, delivery and assessment of informed consent should be initiated for residents upon arrival to surgical training.

Managing colon cancer with intestinal nonrotation, a type of congenital intestinal malrotation, is challenging due to the presence of anatomical abnormalities and severe adhesions. When patients have nonrotation, it is markedly more difficult to determine which vessels correspond to the colic vessels and ileal vessels until all vascular branching patterns become evident. The optimal approach for right-sided colon cancer with intestinal nonrotation has yet to be established. In the present case of ascending colon cancer with intestinal nonrotation, we performed laparoscopic right hemicolectomy with D3 dissection using a modified cranial approach. This approach involves tracing, without resecting, branches from the superior mesenteric vein and superior mesenteric artery in a cranial-to-caudal manner until the ileocolic artery and ileocolic vein, which course toward the cecum, are identified, followed by the dissection of the colic vessels and lymph nodes in a caudal-to-cranial fashion.

BACKGROUND: We assessed feasibility and safety of laparoscopic sigmoidectomy for complicated fistulizing diverticular disease in a tertiary care colorectal center. METHODS: A single-center retrospective study of patients undergoing sigmoidectomy for fistulizing diverticular disease between 2011 and 2021 was realized. Primary outcomes were rates of conversion to open surgery and severe postoperative morbidity at 30 days. Secondary outcomes included rates of postoperative bladder leaks on cystogram. RESULTS: Among the 104 patients, 32.7% had previous laparotomy. Laparoscopy was the initial approach in 103 (99.0%), with 6 (5.8%) conversions to laparotomy. Clavien-Dindo grade ≥ III complication rate at 30 days was 10.6%, including two (1.9%) anastomotic leaks. The median postoperative length of stay was 4.0 days. Seven (6.7%) patients underwent reoperation, six (5.8%) were readmitted, and one (0.9%) died within 30 days. Twelve (11.5%) ileostomies were created initially, and two (1.9%) were created following anastomotic leaks. At last follow-up, 101 (97.1%) patients were stoma-free. Urgent surgeries had a higher rate of severe postoperative complications. Among colovesical fistula patients (n = 73), postoperative cystograms were performed in 56.2%, identifying two out of the three bladder leaks detected on closed suction drains. No differences in postoperative outcomes occurred between groups with and without postoperative cystograms, including Foley catheter removal within seven days (73.2% vs. 90.6%, p = 0.08). CONCLUSIONS: Laparoscopic surgery for complicated fistulizing diverticulitis showed low rates of severe complications, conversions to open surgery and permanent stomas in high-volume colorectal center.

The robotic approach improves the feasibility of minimally invasive colectomy even where there may be an anatomic challenge with laparoscopy. Whether a failure in completing colectomy with this newer technology is associated with worse consequences needs to be considered when evaluating the relative benefit of robotic colectomy. The aim of this study is to evaluate rates of conversion to open surgery after robotic and laparoscopic colectomy and whether outcomes after conversion vary after the two techniques since this has not been well studied. From the American College of Surgeons (ACS) - National Surgical Quality Improvement Program (NSQIP) (2015-2016), patients who underwent elective minimally invasive colectomy were identified. Converted robotic were compared to laparoscopic procedures for patient demographics, co-morbidities; primary procedure and diagnosis, prolonged operation and postoperative complications. Of 36,046 colectomy procedures, 30,808 (85.5%) were laparoscopic, while 5238 (14.5%) were robotic-assisted. There were 3271 (9.1%) conversions to open surgery (laparoscopic: 2959 [9.6%]; robotic: 312 [6%]). Thirty-day postoperative surgical site infection, anastomotic leak, ileus, sepsis, bleeding requiring transfusion, urinary tract infection, reoperation; pulmonary, renal, cardiac/cerebrovascular complications; readmission, hospital stay, and mortality, were similar between the two groups. However, deep vein thrombosis/pulmonary embolism was higher after robotic conversion (4.5% vs. 2.2%, p = 0.01). Conversion was lower after robotic when compared to laparoscopic colectomy. Converted patients had similar outcomes except for vein thromboembolism which was higher after robotic surgery. Robotic technology seems to improve the feasibility of minimally invasive surgery without negatively affecting safety and efficacy even when conversion is required.

INTRODUCTION: Minimally invasive surgery has been increasingly accepted and used in colorectal surgery. Several studies report that robotic surgery may provide advantages over 'conventional' laparoscopy, namely in rectal surgery. This paper provides an account of the first three years of experience with robotic surgery in the Unidade de Patologia Colorretal of the Unidade Local de Saúde S. José. METHODS: Variables were defined to develop a prospective database containing the data of consecutive patients operated by three internationally certified colorectal surgeons using the Da Vinci Xi® system between November 2019 and October 2022. The database was converted into an anonymized version that was used for this study. The analysis was performed on the data of all the patients operated during this period. RESULTS: Eighty patients were included, 47 male, median age 70 years, and median BMI 26 kg/m2 . ASA score was II in 53.7% and III in 41.3% of pa- tients. Of the total, 97.6% had malignant or potentially malignant disease. Operative procedures consisted of 34 colectomies proximal to the splenic flexure, 20 distal colectomies and 26 anterior resections. There were two synchronous resections of liver metastases. Early perioperative outcomes and histopathological results were analyzed: median operative time: 300 minutes; median estimated blood loss: 50 mL; conversion rate: 2.5%; median days until first bowel movement: three days; median length of hospital stay: six days; complication rate: 20%, of which 5% were Clavien III and 0% Clavien IV/V; anastomotic leak rate: 2.5%; 30-day readmission rate: 1.3%; median lymph nodes resected: 20; R0 resection rate: 100%; mesorectal integrity rate: 95,8% complete/near complete. CONCLUSION: Our results show that the adoption of robotic colorectal surgery in our center was safe and resulted in similar or improved short-term clinical outcomes and histopathological results when compared to those described in the literature.
Introdução: A utilização da cirurgia minimamente invasiva no tratamento da patologia colorretal é hoje cientificamente aceite e o seu uso na prática clí- nica diária tem vindo a aumentar de forma sustentada. Diversos estudos indicam que a abordagem robótica pode trazer vantagens sobre a laparoscopia 'convencional', especialmente na cirurgia do reto. Este trabalho descreve e analisa os resultados dos primeiros três anos de cirurgia robótica na Unidade de Patologia Colorretal da Unidade Local de Saúde S. José. Métodos: Foram definidas as variáveis a analisar e construída uma base de dados prospetiva com os dados referentes aos doentes operados conse- cutivamente por três cirurgiões colorretais, acreditados internacionalmente na utilização do sistema Da Vinci Xi®, entre novembro de 2019 e outubro de 2022. A base de dados foi convertida numa versão anonimizada e foi sobre essa mesma que se procedeu à análise de dados. Foram analisados os dados de todos doentes operados nesse período. Resultados: Foram incluídos 80 doentes, 47 homens, mediana de idade de 70 anos e de IMC de 26 kg/m2 . O score ASA era II em 53,7% e III em 41,3% dos doentes. Do total, 97,6% apresentavam doença maligna ou potencialmente maligna. Realizaram-se 34 colectomias proximais ao ângulo esplénico, 20 distais e 26 ressecções anteriores do reto. Houve ressecção síncrona de metástases hepáticas em dois casos. Foram analisados os resultados peri-operatórios a curto prazo e histopatológicos: duração (mediana): 300 minutos; perda hemática estimada (mediana): 50 mL; taxa de conversão: 2,5%; dias até retomar trânsito intestinal (mediana): três dias; dias de internamento (mediana): seis dias; taxa de complicações pós-operatórias: 20%, das quais 5% Clavien III e 0% Clavien IV/V; taxa de deiscência anastomótica: 2,5%; taxa de reintervenção: 2,5%; taxa de readmissão pós-alta: 1,3%; gânglios linfáticos ressecados (mediana): 20; taxa de ressecção R0: 100%; taxa de integridade mesorretal: 95,8% completo/quase completo. Conclusão: Os nossos resultados mostram que a introdução da cirurgia colorretal robótica no nosso centro foi segura e garantiu resultados clínicos a curto prazo e histopatológicos semelhantes ou favoráveis face aos descritos na literatura.

BACKGROUND: There is a lack of literature on the length of the terminal ileum to be resected in right hemicolectomy for colon cancer. Therefore, we aimed to determine the mean ileal loop length and the effect of this variation on postoperative complications and long-term oncological outcomes in patients who underwent right hemicolectomy. METHODS: Right hemicolectomy surgeries performed for colon cancer in a tertiary care hospital between January 2011 and December 2018 were retrospectively analyzed from a prospective database. Two patient groups were established based on the mean length of the resected ileum above and below 7 cm. The two groups were compared for clinicopathological data, postoperative complications, mortality, long-term overall survival (OS) and disease-free survival (DFS). The factors contributing to OS and DFS were analyzed. RESULTS: The study included 217 patients. Body mass index (BMI) values were significantly higher in the ileum resection length > 7 cm group (p = 0.009). Pathological N stage, tumor diameter, and number of metastatic lymph nodes were significantly higher in the ileum resection length > 7 cm group (p = 0.001, p = 0.001, and p = 0.026, respectively). There was no significant difference for postoperative complication and mortality rates between the two groups. The mean follow-up period was 61.2 months (2-120) in all patients. The total number of deaths was 29 (11.7%) while the 60-month OS was 83.5% and 50-month DFS was 81.8%. There was no significant difference between the groups in terms of OS and DFS rates (p > 0.05). CONCLUSIONS: Excessive resection of the distal ileum in right hemicolectomy does not provide any benefit in terms of prognosis and complications.The ileum resection length and values close to it in our study appear to be sufficient.

BACKGROUND: Because of the adverse effects of morphine and its derivatives, non-opioid analgesia procedures are proposed after outpatient surgery. Without opioids, the ability to provide quality analgesia after the patient returns home may be questioned. We examined whether an opioid-free strategy could ensure satisfactory analgesia after ambulatory laparoscopic colectomy. METHODS: We performed a retrospective observational single-center study (of prospective collected database) including all patients eligible for scheduled outpatient colectomy. Postoperative analgesia was provided by paracetamol and nefopam. Postoperative follow-up included pain at mobilization (assessed by a numerical rating scale, NRS), hemodynamic variables, temperature, resumption of transit and biological markers of postoperative inflammation. The primary outcome was the proportion of patients with moderate to severe pain (NRS > 4) the day after surgery. RESULTS: Data from 144 patients were analyzed. The majority were men aged 59 ± 12 years with a mean BMI of 27 [25-30] kg/m2. ASA scores were 1 for 14%, 2 for 59% and 3 for 27% of patients. Forty-seven patients (33%) underwent surgery for cancer, 94 for sigmoiditis (65%) and 3 (2%) for another colonic pathology. Postoperative pain was affected by time since surgery (Q3 = 52.4,p < 0.001) and decreased significantly from day to day. The incidence of moderate to severe pain at mobilization (NRS > 4) on the first day after surgery was (0.19; 95% CI, 0.13-0.27). CONCLUSION: Non-opioid analgesia after ambulatory laparoscopic colectomy seems efficient to ensure adequate analgesia. This therapeutic strategy makes it possible to avoid the adverse effects of opioids. TRIAL REGISTRATION: The study was retrospectively registered and approved by the relevant institutional review board (CERAR) reference IRB 00010254-2018 - 188).

BACKGROUND: The cranial-caudal-medial approach (CCMA) has been proposed for laparoscopic right hemicolectomy nowadays. This study aimed to investigate the safety and oncological efficacy of CCMA in the treatment of right-sided colon cancer compared to the medial-lateral approach (MLA). METHODS: Patients diagnosed with right-sided colon cancer were included from February 2015 to June 2018, retrospectively, dividing into the CCMA group and the MLA group. We compared the basic characteristics and the short-term and long-term outcomes in two groups. RESULTS: Two hundred and ninety-six patients were included in this study. The baseline characteristics were similar in two groups. Compared with MLA group, CCMA group exhibited shorter operation time (136.3 ± 25.3 min vs. 151.6 ± 21.5 min, P < 0.001), lower estimated blood loss (44.1 ± 15.2 ml vs. 51.4 ± 26.9 min, P = 0.010), and more harvested lymph nodes (18.5 ± 7.1 vs. 16.5 ± 5.7, P = 0.021). The 5-year overall survival (OS) rate for the CCMA group was 76.5%, and the 5-year disease-free survival (DFS) rate was 72.3%, both of which were not inferior to the MLA group. No significant difference was found between two groups in terms of other clinical parameters. CONCLUSION: The CCMA in laparoscopic right hemicolectomy is safe and feasible, making the anatomical plane clearer. This approach can shorten the operation time, reduce intraoperative blood loss, harvest more lymph nodes, and yield satisfactory oncological outcomes.

INTRODUCTION: Right hemicolectomy (RHC) remains the treatment standard for goblet cell adenocarcinoma (GCA), despite limited evidence supporting survival benefit. This study aims to explore factors influencing surgical management and survival outcomes among patients treated with RHC or appendicectomy using NCRAS (UK) and SEER (USA) data. METHODS: A retrospective analysis was conducted using 998 (NCRAS) and 1703 (SEER) cases. Factors influencing procedure type were explored using logistic regression analyses. Overall survival (OS) probabilities and Kaplan-Meier (KM) plots were generated using KM analysis and the log-rank test compared survival between groups. Cox regression analyses were performed to assess hazard ratios. RESULTS: The NCRAS analysis revealed that age and regional stage disease were determinants of undergoing RHC, with all age groups showing similar odds of receiving RHC, excluding the 75+ age group. The SEER analysis revealed tumour size > 2 cm, and receipt of chemotherapy were determinants of undergoing RHC, unlike the distant stage, which was associated with appendicectomy. Surgery type was not a significant predictor of OS in both analyses. In NCRAS, age and stage were significant predictors of OS. In SEER, age, stage, and Black race were significant predictors of worse OS. CONCLUSIONS: The study shows variations in the surgical management of GCA, with limited evidence to support a widespread recommendation for RHC.
