Background: Complete mesocolic excision (CME) has been introduced from open surgery, to compare right colon cancer surgery to total mesorectal excision for rectal cancer and it is currently being applied by robotic approach. CME concept is based on the complete removal of right mesocolon and the dissection deep at the level of the central feeding vessels. Aside the CME, intracorporeal anastomosis completes a total minimally invasive approach to the treatment of right colon cancer. This study retrospectively analyzed the feasibility and efficacy of robotic CME and intracorporeal anastomosis in a cohort of consecutive patients affected with right colon cancer.

Methods: The data of 110 patients undergone a robotic CME with IA anastomosis for right colon cancer from 2018 to 2023 were prospectively collected and retrospectively analyzed. Intraoperative, postoperative, and short-middle term outcomes were considered for analysis, as well as pathologic and oncologic outcomes. A time-to-event analysis was performed using the Kaplan-Meier method for OS and DFS.

Results: All patients underwent a robotic right colectomy. Median operative time was 184 min, blood loss was negligible, no intraoperative complications occurred. Three conversions (2.7%) were experienced due to bulky lymph nodes and severe local advanced tumor. Mean postoperative stay was 6 days. Six postoperative complications occurred, 4 postoperative ileus, 1 late dehiscence of the colonic stump and an iatrogenic colonic perforation. The latter needed reintervention.

Conclusions: Robotic CME with central vessels ligation seems feasible and safe, with acceptable morbidity and adequate short-middle term outcomes.

Background: Our aim was to describe the clinical outcomes of surgical interventions performed for the management of colonoscopy-related perforations and to compare these outcomes with those of matched colorectal surgeries performed in elective and emergency settings.

Methods: We included patients with endoscopic colonic perforation who underwent surgical intervention from the 2014-2017 National Surgery Quality Improvement Program participant use data colorectal targeted procedure file. The primary outcome in this study was short term surgical morbidity and mortality. Patients (group 1) were matched with 1:2 ratio to control patients undergoing same surgical interventions for other indications on an elective (group 2) or emergency basis (group 3). Bivariate analysis was conducted to compare categorical variables between the three groups, and multivariate logistic regression was used to evaluate the association between the surgical indication and 30-day postoperative outcomes.

Results: A total of 590 patients were included. The average age of the patients was 66.5±13.6 with female gender predominance (381, 64.6%) The majority of patients underwent open colectomy (365, 61.9%) while the rest had suturing (140, 23.7%) and laparoscopic colectomy (85, 14.4%). Overall mortality occurred in 4.1% and no statistically significant difference in mortality was found between the three techniques (P=0.468). Composite morbidity occurred in 163 patients (27.6%). It was significantly lower in laparoscopic colectomy (14.1%) compared to 30.2% and 29.4% in open colectomy and suturing approaches (P=0.014). Patients undergoing colectomy for iatrogenic colonic perforation had less mortality, infection rates and sepsis, as well as bleeding episodes compared to those who had colectomy on an emergent basis. Outcomes were comparable between the former group and patients undergoing elective colectomy for other indications.

Conclusions: Surgical management of colonoscopy related perforations is safe and effective with outcomes that are similar to that of patients undergoing elective colectomy.

Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive tumor with poor prognosis and rising incidence globally. Multimodal therapy that includes surgical resection and chemotherapy with or without radiation offers the best chance for optimal outcomes. The development of established criteria for anatomic staging of local primary tumors into potentially resectable (PR), borderline resectable (BR), and locally advanced (LA) has greatly clarified the optimal treatment strategies. While upfront surgical resection was traditionally the recommended approach for localized PDAC, increasingly neoadjuvant therapy (NT) is recommended prior to surgery. Whereas NT can lead to downstaging that facilitates surgical resection for BR/LA cancers, NT also enhances patient selection for surgery, improves margin-negative resection rates, and increases the odds of completing multimodality therapy for all patients with PDAC. Herein, we review the rationale for NT for localized PDAC and summarize existing and ongoing literature.
