Background/objectives: Open right hemicolectomy (ORH) remains the standard approach for locally advanced right-sided colon cancer. Minimally invasive techniques are increasingly applied in earlier disease stages; however, evidence regarding long-term oncologic outcomes in advanced tumors remains limited. This study aimed to compare the perioperative and oncologic outcomes of ORH versus robotic right hemicolectomy (RRH). Methods: In this single-center study, a prospectively maintained database of consecutive right hemicolectomy patients (2010–2020) was analyzed. The primary endpoint was overall survival (OS). Secondary endpoints included disease-free survival (DFS), perioperative outcomes, and histopathological quality. Additionally, a subgroup analysis was performed for T4 tumors. Results: A total of 198 patients was included, comprising 77 that underwent ORH and 121 that underwent RRH. RRH achieved oncologic outcomes comparable with ORH, with similar R0 resection rates (96% vs. 97.5%, p = 0.547) and lymph node yields (median of 18 nodes in both groups, p = 0.828). OS did not differ significantly (ORH, 45.3 months vs. RRH, 49.9 months, p = 0.130). DFS was longer in RRH (ORH, 42.2 months vs. RRH, 49.1 months, p = 0.029; HR = 0.575, 95% CI 0.349–0.947); however, this difference disappeared after adjustment for tumor stage. No survival advantage was observed in the T4 subgroup. Conclusions: RRH provides oncologic outcomes comparable to open surgery while offering perioperative advantages, even in locally advanced colon cancer. When performed in experienced high-volume centers, RRH represents a safe and oncologically sound alternative to ORH and may contribute to expanding MIC beyond early-stage disease. Full article

Erythema gyratum repens (EGR) is a rare figurate erythema strongly associated with internal malignancy and recognized as one of the most specific cutaneous paraneoplastic syndromes. Its recognition is clinically important, as it frequently precedes the diagnosis of an underlying neoplasm. We report the case of an 80-year-old woman who presented to the emergency department with a rapidly progressive, intensely pruritic eruption displaying a characteristic concentric “wood-grain” pattern. Laboratory evaluation revealed iron-deficiency anemia. Contrast-enhanced computed tomography identified a right-sided colonic mass, and colonoscopy with biopsy confirmed adenocarcinoma of the cecum. The patient underwent elective laparoscopic right hemicolectomy with complete tumor resection (pT3N0, microsatellite stable). Following surgery, the cutaneous lesions resolved completely and did not recur during follow-up. This case highlights erythema gyratum repens as a clinically relevant early marker of colorectal cancer and emphasizes the importance of prompt recognition of this distinctive dermatosis to trigger urgent and comprehensive malignancy screening, enabling timely diagnosis and definitive treatment.

Background and Objectives: Laparoscopic procedures have become a routine approach in colorectal surgery. We aimed to evaluate intraoperative, postoperative and pathological outcomes of laparoscopic right hemicolectomy in comparison with open right hemicolectomy. Materials and Methods: We reviewed our database for colorectal surgery and collected data regarding right hemicolectomies performed over a period of 10 years regarding patient characteristics, operative outcomes and postoperative outcomes. We compared laparoscopic with open right hemicolectomies. All the anastomoses in the laparoscopic group were performed intracorporeally. Results: We included 384 cases, 74 (19.3%) laparoscopic and 310 (80.7%) open right hemicolectomies. Baseline characteristics were comparable between the two groups. Conversion rate was low (2.7%). A drain was placed more often in the open colectomies (p < 0.001). Laparoscopic colectomies lasted longer by 25 min on average in the entire cohort (p = 0.002) and by 30 min in cancer-only cases without concomitant procedures (p < 0.001). Laparoscopic procedures yielded more lymph nodes (p = 0.007), as well as longer distal resection margins (p < 0.001) and total specimen (p < 0.001). There was no difference between the two approaches concerning intraoperative complications (p = 0.36) or need for transfusion (p = 0.708). There was also no difference regarding overall (p = 0.361) or major complications (p = 1), as well as anastomotic leak (p = 0.475), surgical site infections (p = 0.275) or readmission rates (p = 1). Hospitalisation duration was shorter by 3 days after laparoscopic surgery in the entire cohort (p < 0.001), as well as when cancer-only cases without concomitant procedures were considered (p < 0.001). Conclusions: Laparoscopic right hemicolectomy with intracorporeal anastomosis provides perioperative safety and pathology outcomes comparable to open surgery, while significantly reducing hospital stay.

Background: Right hemicolectomy remains the standard surgical treatment for right colon diseases. This study evaluates robotic versus laparoscopic approaches to determine optimal, minimally invasive strategies, balancing technical efficacy with healthcare economics. Materials and Methods: This retrospective study evaluates robotic versus laparoscopic approaches using data from 46 studies (2003–2025) involving 36,868 patients (6,312 robotic, 30,547 laparoscopic). Primary outcomes assessed were lymph node yield, operative time, and hospital stay; secondary outcomes included blood loss, conversion rates, infections, readmissions, and costs. Results: Concerning robotic surgery, lymph node harvest was higher (MD 1.34 for CME; MD 1.27 for non-CME). Laparoscopy showed shorter operative times (MD 25.73 for CME; MD 42.45 for non-CME). Hospital stays showed no significant difference. Robotics demonstrated lower blood loss in non-CME cases (MD -0.38). Conversion rates favored robotics (1% vs. 10% for CME; 4% vs. 8% for non-CME). No significant differences were found in wound infections or non-CME readmissions, though robotics showed lower CME readmission costs (MD 5.34). There were several study-acknowledged limitations, including surgeon preference bias, protocol variability, learning curves, and evolving techniques over the 22-year period. Cost analyses considered both direct surgical expenses and postoperative care. Conclusions: While robotics offers advantages in oncological resection and procedural stability, laparoscopy maintains efficiency benefits. These findings contribute to ongoing discussions about optimal, minimally invasive approaches for right colon pathologies, balancing technical efficacy with healthcare economics. By comparing surgical techniques, surgeon expertise, patient characteristics, and healthcare costs across multiple institutions, this study seeks to provide meaningful insights for surgical decision-making and further standardization.

Background: Liver cirrhosis increases perioperative risk in colorectal cancer surgery, yet data on long-term outcomes remain limited. In this study, we evaluated postoperative morbidity, mortality, and survival in cirrhotic patients. Methods: In this single-center retrospective cohort, 53 cirrhotic patients undergoing elective colectomy or proctectomy (2011–2022) were propensity score-matched 1:1 with non-cirrhotic controls. Perioperative variables, complications, and survival were analyzed. Subgroup analyses were performed for right hemicolectomy and non-right hemicolectomy procedures. Kaplan–Meier and logistic regression analyses were implemented to assess outcomes and risk factors. Results: Cirrhotic patients had higher preoperative MELD-Na scores and lower albumin and hemoglobin levels. They experienced greater blood loss, longer operative times, more ICU admissions, and higher rates of major complications (18.9% vs. 3.8%, p = 0.01). Mortality was higher at in-hospital (7.5% vs. 0%), 3-month (9.4% vs. 0%), and 60-month (66% vs. 28.3%) intervals, and these patients’ overall survival was shorter (70.7 vs. 116.8 months, p < 0.001). The subgroup analysis showed that the adverse impact of cirrhosis persisted for both right hemicolectomy and non-right hemicolectomy procedures, with significantly worse long-term survival in cirrhotic patients. Postoperative complications after right hemicolectomy did not differ significantly between groups. Among cirrhotic patients, Child–Turcotte–Pugh class B predicted worse survival than class A (40.1 vs. 84.8 months, p = 0.006). Preoperative hypoalbuminemia (<3.5 g/dL) independently predicted long-term mortality (HR = 3.93). Conclusions: Elective colorectal surgery in patients with cirrhosis is associated with increased perioperative complications and significantly reduced long-term survival. However, postoperative outcomes after right hemicolectomy in cirrhotic patients were comparable to those of non-cirrhotic patients, despite their persistently poorer long-term survival. Optimization of nutritional status and careful preoperative assessment of hepatic reserve are essential to improving outcomes in this high-risk population. Full article

Background: Less than 1% of all colorectal cancers (CRCs) are primary colorectal signet-ring cell carcinomas (SRCCs), which represent an uncommon and aggressive histological subtype. Given their subtle onset and rapid progression, these are often diagnosed in an advanced stage, and can be distinguished by the presence of mucin-producing signet-ring cells. Synchronous colonic metastases at initial diagnosis are rather uncommon. Case presentation: We report the case of a 65-year-old male patient who underwent a routine colonoscopy following a positive fecal immunochemical test (FIT). The patient had no remarkable medical history and was asymptomatic. A 3 cm semi-pedunculated polyp and several smaller depressed lesions, 2 cm maximum in diameter, were observed in the descending colon during the colonoscopy. Multiple biopsies were obtained. The lesions were found to be SRCC according to histopathological examination. There was no sign of extra-colonic metastases on the computed tomography (CT). The patient was referred for extensive hemicolectomy, regional lymphadenectomy, and adjuvant chemotherapy. Conclusions: This article provides a thorough literature review on this uncommon presentation and discussion regarding the current understanding of the pathogenesis, clinical manifestations, and management strategies of SRCC. This case highlights the importance of routine screening in detecting aggressive malignancies like SRCC in asymptomatic individuals. Early identification through colonoscopy can lead to timely intervention, potentially improving prognosis. Full article

Left colon diverticular disease (LCDD) is prevalent in the aging populations of industrialized countries, with many patients requiring surgery. Elective surgery decisions should consider individual health conditions and quality of life. Typically, surgery is recommended six weeks after an acute episode. This scoping review, following PRISMA-ScR guidelines, analyzed the literature on elective LCDD surgery, focusing on inferior mesenteric artery (IMA) ligation, splenic flexure mobilization (SFM), surgical approach, and extent of resection. The databases searched included PubMed, Embase, and Cochrane Library up to May 2025. Twenty studies met the inclusion criteria: 2 randomized trials (RCTs), 6 systematic reviews, 3 prospective studies, and 9 retrospective cohorts. The findings suggest preserving the IMA and selectively omitting SFM may reduce minor complications without compromising safety. Resection should reach the rectosigmoid junction and include only the affected colon segment. Minimally invasive techniques, especially laparoscopic surgery improve outcomes, reduce morbidity, and are more cost-effective than open surgery. Robotic approaches offer new options for complex cases. Surgical strategies must be tailored to disease severity, patient comorbidities, and anatomy. Further prospective studies are needed to refine guidelines and support personalized surgical decisions in LCDD management. Full article

Background: Indocyanine green (ICG)-guided surgery is an emerging technique to enhance intraoperative visualization of nodes and tumor location. However, there is no uniform protocol regarding the optimal timing, dosage, or injection site for ICG in colorectal cancer surgery. We assess the feasibility of ICG injection at the anorectal junction immediately before surgery to safely identify the inferior mesenteric artery (IMA). Methods: This was a prospective study involving robotic left hemicolectomy or anterior resection of the rectum for primary colorectal cancer in 2024 in a single center. A total of 10–20 mg was injected into the anorectal submucosa at four quadrants circumferentially using an anoscope immediately before robot docking. Results: In this first study, ICG allowed us to identify the IMA in 84.6% of 26 patients (mean age 66.5 years; BMI 26.7 kg/m²), without intraoperative medical and surgical complications. Elevated BMI correlated with failure of IMA detection (r = −0.77, p < 0.001), despite high ICG doses trending toward improved vascular visualization (p = 0.097). A mean of 22 lymph nodes was harvested after ICG injection, with yields unaffected by the quality of IMA visualization. Conclusions: Submucosal injection of ICG is a feasible and easily adoptable option for early identification of the IMA, thereby preventing major vascular injuries, particularly in patients with challenging anatomy. A standardized protocol was implemented to improve reliability. Full article

Introduction: Appendiceal neuroendocrine neoplasms (aNENs) are the most common malignant appendiceal neoplasms. Localized aNENs are typically managed with an appendectomy; however, right colectomy may be necessary in patients with a high risk of nodal disease. However, the role of right hemicolectomy and the optimal surveillance strategy, particularly for tumors between 1 and 2 cm, remains controversial. Material and Methods: This retrospective, observational study evaluated patients diagnosed with aNENs between January 1995 and July 2015 at two tertiary centers in Ireland and Italy. Data were extracted from a prospectively maintained registry and included clinical, pathological, and therapeutic variables, as well as follow-up outcomes. Results: Forty-three patients (41.8% male; median age 27.5 years) were included, with a median follow-up of 49 months. The median tumor size was 6.4 mm (range: 0.6–40 mm). The majority were G1 tumors (58%), and staging distribution was predominantly Stage I (60%). While no significant differences in demographics or tumor features were observed between centers, completion right hemicolectomies were more frequent in the Irish cohort (p = 0.04). Follow-up practices varied, with more intensive imaging and biochemical monitoring observed in the Italian cohort. Overall prognosis was excellent, with a single case of recurrence during the study period. Conclusions: Most aNENs are effectively managed with appendectomy alone, and routine follow-up may be unnecessary in the absence of adverse pathological features. Accurate risk stratification, driven by comprehensive histopathological assessment, is critical for optimizing management and surveillance strategies. Full article

Background and Clinical Significance: Preoperative planning is crucial for improving surgical safety and outcomes, particularly in minimally invasive surgery, where tactile feedback is absent. Three-dimensional (3D) printing offers patient-specific anatomical models that can enhance surgical planning. Its application in diverticular disease remains underexplored. Case Presentation: We present the case of a 65-year-old male with recurrent diverticulitis involving the sigmoid and descending colon. After conservative management of an acute episode, preoperative imaging revealed extensive diverticulosis. A patient-specific 3D-printed model was created from CT images to plan the surgical approach. The model helped determine the need for a left hemicolectomy rather than a simple sigmoidectomy, anticipated technical challenges such as lowering the left colic flexure and ligating the inferior mesenteric artery, and improved patient counseling. The surgery was performed laparoscopically without complications, and the patient was discharged on postoperative day six. Histology confirmed diverticulosis with perivisceritis and reactive lymphadenitis. Conclusions: This case demonstrates the potential of 3D printing to optimize surgical planning in diverticular disease, enabling tailored resections and improving operative strategy. Broader adoption may be limited by time and cost but offers clear educational and clinical benefits. Full article

Adenoma-like adenocarcinoma (ALAC) of the colon is a recently recognized histological subtype of colorectal adenocarcinoma, characterized by a villous architecture, low-grade cytologic atypia, and deceptive bland morphology despite its invasive potential, which can mimic non-invasive adenomas, leading to underdiagnosis in limited biopsy samples. Herein, we report the case of an 81-year-old male presenting with right-upper-quadrant pain that was found to have a hepatic abscess and a 4 cm villous lesion in the ascending colon. Histopathological examination of the right hemicolectomy specimen revealed a villous adenocarcinoma with invasion of the muscularis propria, consistent with adenoma-like adenocarcinoma. Isolated loss of PMS2 indicated a mismatch repair deficiency. However, adjuvant therapy was not indicated. The patient remained recurrence-free for three years, until he died from unrelated causes in the context of progressive frailty and comorbidities, with no evidence of cancer progression. This case highlights the diagnostic challenges posed by ALAC and underscores the importance of recognizing its distinct morphological features. Awareness of this entity is essential to avoid misclassification and ensure adequate treatment, especially given its typically favorable prognosis with low metastatic potential. Full article

(1) Minimally invasive techniques are standard in colorectal surgery, though complete mesocolic excision (CME) with central lymphadenectomy remains technically demanding. Robotic systems may address these challenges. While the DaVinci system is well established, the modular Dexter system allows rapid switching between laparoscopy and robotics. (2) This prospective single-surgeon study compared right hemicolectomy with CME and intracorporeal anastomosis using Dexter, DaVinci, and conventional laparoscopy in 75 patients (25 per group) at a German high-volume center. Outcomes assessed included operative time, complications, lymph node yield, and CME quality. (3) Mean operative time was longest with DaVinci (190.5 min) versus Dexter (164.8 min) and laparoscopy (152.6 min). Intracorporeal anastomosis was more frequent in robotic groups. No significant differences were found in lymph node yield, CME quality, postoperative complications, length of stay, or survival. (4) The ability to convert briefly to laparoscopy during Dexter procedures helped manage challenging steps, especially during the learning curve. The results suggest that Dexter is a safe, feasible alternative to established robotic and laparoscopic techniques, with the added benefits of flexibility and integration into existing workflows.

Goblet cell adenocarcinomas (GCAs) are an exceedingly rare subtype of tumors, almost exclusively occurring in the appendix, and characterized by features overlapping both adenocarcinomas and neuroendocrine tumors (NETs), which has historically led to confusion and varied nomenclature. This study presents a comprehensive review of the literature highlighting particularities of this type of malignancy, starting from a rare case of a 54-year-old female operated on in our clinic for an appendiceal tumor, initially suspected to be a mucinous neoplasm based on colonoscopic biopsy, which was ultimately confirmed to be goblet cell adenocarcinoma on both intraoperative frozen section and definitive pathological examination. Exhibiting signs and symptoms associated with an abdominal mass, she underwent a right hemicolectomy with partial omentectomy for locally advanced, high-grade, invasive goblet cell adenocarcinoma of the appendix with lymphatic macro metastases and epiploic invasion, categorized as AJCC stage IVb carcinomatosis. The patient received FOLFOX adjuvant. Six months later, she required reoperation due to the progression of carcinomatosis, which was again confirmed histopathologically. A second-line oncological protocol comprising irinotecan, capecitabine, and bevacizumab was initiated. Given the rarity of GCAs and the absence of a consensus on nomenclature, classification, and diagnostic criteria, we conducted a comprehensive literature review to highlight current trends related to this entity, including its classification within different systems (Tang, Yozu, WHO, AJCC), as well as the therapeutic surgical approaches—ranging from simple appendectomy to extensive multiorgan resection, cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC), and the use of systemic therapy. Adhering to these recommendations will enhance communication among pathologists, surgeons, and oncologists regarding the natural history and prognosis of this rare malignancy. Full article

Objective: The aim of this prospective comparative study is to report our experience with 3D laparoscopy in terms of surgeon’s discomfort with 3D vision, and to compare clinical outcomes with 2D laparoscopy in oncological colorectal surgery. Methods: From 2016 to 2017, all consecutive patients who underwent elective colorectal surgery for malignancy were enrolled. Based on surgery, patients were grouped as follows: group A, right hemicolectomy; group B, left hemicolectomy; group C, sigmoidectomy; and group D, anterior resection of the rectum. Results: In total, 171 patients were included, of which 61 were in group A (45 3D and 16 2D), 18 in group B (15 3D and 3 2D), 44 in group C (30 3D and 14 2D) and 48 in group D (36 3D and 12 2D). The surgeon’s discomfort did not occur due to the 3D vision. Complication rate and mean length of hospital stay (LOS) were lower in the 3D group in comparison to 2D, even if without statistically significant differences, in group B (6.6% versus 66.6% and LOS 6.1 ± 5.2 versus 23 ± 21 days), C (6.7% versus 21.4% and LOS 5.9 ± 2.5 versus 9 ± 8.4 days) and D (27.8% versus 50% and LOS 11.9 ± 16 versus 13 ± 11.8 days), respectively. Conclusions: Despite the lack of statistically significant differences between 2D and 3D laparoscopy, this study reports promising trends in favor of 3D laparoscopy, particularly for complex procedures such as anterior resection. Further randomized prospective studies with larger sample sizes and longer follow-up are necessary to conclusively determine the clinical impact of 3D laparoscopy in colorectal surgery. Full article

Background: Looking for anomalies and vascular control gains a central role in colon cancer surgery. Complete mesocolic excision (CME) presents technical challenges, primarily due to the considerable variability in the arterial configuration of the right colon. The importance of understanding colonic vascular anatomy has become more prominent with the adoption of this surgical technique. The aim of this study is to systematically review the vascular anatomical variations in the superior mesenteric artery (SMA) in the setting of extended lymphadenectomy for CME in right colon cancer and to show its impact in clinical practice. Methods: A systematic review of the literature on Medline (PubMed), Web of Science (WOS), and Scopus was performed according to PRISMA guidelines. The following criteria were set for inclusion: (1) studies reporting minimally invasive (robotic, laparoscopic, and hybrid techniques) or open CME/D3 lymphadenectomy; (2) studies reporting patients with right-sided colon cancer; (3) studies reporting the description or illustration of SMA variations. The methodological quality of all included studies was evaluated using the Newcastle–Ottawa Scale (NOS). Results: After the literature search, 800 studies were recorded, 31 studies underwent full-text reviews, and 9 studies met the inclusion criteria. All studies reported vascular variations in SMA, and the total number of patients was 813. No intraoperative complications were reported. In 6.4% of patients, post-operative bleeding occurred. Conclusions: Vascular anatomical variations are not a rare entity. In experienced centers, vascular anomalies are not associated with an increase in complications, both in traditional open and minimally invasive surgery (MIS). However, in MIS, full access to central vessels and intraoperative vascular control, moderate retraction, safety maneuvers, and accurate vascular dissection are mandatory. Full article
