RESUMO
OBJECTIVE: To develop and analyze a risk-adjusted cumulative sum (RA-CUSUM) chart as a potential method to monitor individual surgeon performance in robotic total mesorectal excision (TME) for rectal cancer. SUMMARY BACKGROUND DATA: Currently, surgeons lack real-time tools to monitor and enhance their performance beyond residency completion. While national quality programs exist, granular, individual-level data is crucial for continuous improvement. Previous studies suggest CUSUM charts hold promise in identifying performance trends and outliers. METHODS: This retrospective study analyzed data from 640 robotic TME cases performed by 12 surgeons at two institutions. RA-CUSUM charts were generated for three outcomes: complications, operative time, and length of stay. RESULTS: The overall RA-CUSUM curves for operative time and complications showed an initial learning phase followed by a plateau or downward slope, indicating proficiency or improvement. However, individual surgeon curves revealed significant heterogeneity. Three surgeons consistently excelled in operative time, while five minimized complications most effectively. Potential quality improvement could be implemented to drive performance toward positive outliers. No differences were found in unadjusted outcomes, including conversion, number of lymph nodes harvested, and positive circumferential margins. CONCLUSIONS: The RA-CUSUM chart is a promising method for identifying individual surgeon performance in robotic TME. It could help surgeons, teams, and leaders identify improvement areas and benchmark themselves against positive outliers. Further studies are needed to explore the potential of RA-CUSUM for implementing interventions to improve surgical quality.
RESUMO
OBJECTIVE: This study aims to assess the costs of a Same-Day Discharge Enhanced Recovery Pathway (SDD) for diverting loop ileostomy closure compared to a standard institutional enhanced recovery protocol (ERP). SUMMARY BACKGROUND DATA: Every year, 50,155 patients in the United States undergo temporary stoma reversal. While ambulatory stoma closure has shown promise, widespread adoption remains slow. This study builds on previous research, focusing on the costs of a novel SDD protocol introduced in 2020. METHODS: A retrospective case-control study was conducted at Mayo Clinic, Rochester, Minnesota, and Mayo Clinic, Jacksonville, Florida, comparing patients undergoing same-day discharge diverting loop ileostomy closure (SDD) from August 2020 to February 2023 to those in a matched cohort receiving standard inpatient ERP. Patients were matched based on age, sex, ASA score, surgery period, and hospital. Primary outcomes included direct hospitalization and additional costs in the 30 days post-discharge. RESULTS: The SDD group (n=118) demonstrated a significant reduction in median index episode hospitalization and 30-day post-operative costs compared to the inpatient group (n=236), with savings of $4,827 per patient. Complication rates were similar, and so were readmission and reoperation rates. CONCLUSIONS: Implementation of the SDD for diverting loop ileostomy closure is associated with substantial cost savings without compromising patient outcomes. The study advocates for a shift towards same-day discharge protocols, offering economic benefits and potential improvements in healthcare resource utilization.
RESUMO
INTRODUCTION: Presacral neuroendocrine neoplasms (PNENs) are rare tumors, with limited data on management and outcomes. METHODS: A retrospective review of institutional medical records was conducted to identify all patients with PNENs between 2008 and 2022. Data collection included demographics, symptoms, imaging, surgical approaches, pathology, complications, and long-term outcomes. RESULTS: Twelve patients were identified; two-thirds were female, averaging 44.8 years of age, and, for the most part, presenting with back pain, constipation, and abdominal discomfort. Preoperative imaging included computed tomography scans and magnetic resonance images, with somatostatin receptor imaging and biopsies being common. Half of the patients had metastatic disease on presentation. Surgical approach varied, with anterior, posterior, and combined techniques used, often involving muscle transection and coccygectomy. Short-term complications affected one-quarter of patients. Pathologically, PNENs were mainly well-differentiated grade 2 tumors with positive synaptophysin and chromogranin A. Associated anomalies were common, with tail-gut cysts prevalent. Mean tumor diameter was 6.3 cm. Four patients received long-term adjuvant therapy. Disease progression necessitated additional interventions, including surgery and various chemotherapy regimens. Skeletal, liver, thyroid, lung, and pancreatic metastases occurred during follow-up, with no mortality reported. Kaplan-Meier analysis showed a 5-year local recurrence rate of 23.8%, disease progression rate of 14.3%, and de novo metastases rate of 30%. CONCLUSION: The study underscores the complex management of PNENs and emphasizes the need for multicenter research to better understand and manage these tumors. It provides valuable insights into surgical outcomes, recurrence rates, and overall survival, guiding future treatment strategies for PNEN patients.

BACKGROUND: Concerns persist regarding the effectiveness of robotic proctectomy when compared with open proctectomy for locally advanced rectal cancer with a high risk of circumferential resection margin involvement. OBJECTIVE: Comparison of surrogate cancer outcomes following robotic versus open proctectomy in this subpopulation. DESIGN: Retrospective cohort study. SETTING: Three academic hospitals (Mayo Clinic Arizona, Florida, and Rochester) through the Mayo Data Explorer platform. PATIENTS: Patients at high risk of circumferential resection margin involvement were selected based on the magnetic resonance imaging-based definition from Mercury I and II trials. PRIMARY AND SECONDARY OUTCOME MEASURES: Rate of pathologic circumferential resection margin involvement (≤1 mm), mesorectal grading, rate of distal margin involvement. RESULTS: Out of 413 patients, 125 (30%) underwent open and 288 (70%) robotic proctectomy. Open proctectomy was significantly associated with a greater proportion of cT4 tumors (39.3% vs. 24.8%, p = 0.021), multivisceral/concomitant resections (40.8% vs. 18.4%, p < 0.001) and less frequent total neoadjuvant therapy use (17.1% vs. 47.1%, p = 0.001). Robotic proctectomy was less commonly associated with pathologic circumferential resection margin involvement (7.3% vs. 17.6%, p = 0.002), including after adjustment for cT stage, neoadjuvant therapy, and multivisceral resection (OR 0.326, 95% CI, 0.157-0.670, p = 0.002). Propensity score-matching on 66 patients per group and related multivariable analysis no longer indicated any reduction of circumferential positive margin rate associated with robotic surgery (p = 0.86 and p = 0.18). Mesorectal grading was comparable (incomplete mesorectum in 6% RP patients vs. 11.8% OP patients, p = 0.327). All cases had negative distal resection margins. LIMITATION: Retrospective design. CONCLUSION: In patients with locally advanced rectal cancer at high risk of circumferential resection margin involvement, robotic proctectomy is an effective approach and could be pursued when technically possible as an alternative to open proctectomy.

RESUMO
AIM: Recent evidence challenges the current standard of offering surgery to patients with ileocaecal Crohn's disease (CD) only when they present complications of the disease. The aim of this study was to compare short-term results of patients who underwent primary ileocaecal resection for either inflammatory (luminal disease, earlier in the disease course) or complicated phenotypes, hypothesizing that the latter would be associated with worse postoperative outcomes. METHOD: A retrospective, multicentre comparative analysis was performed including patients operated on for primary ileocaecal CD at 12 referral centres. Patients were divided into two groups according to indication of surgery for inflammatory (ICD) or complicated (CCD) phenotype. Short-term results were compared. RESULTS: A total of 2013 patients were included, with 291 (14.5%) in the ICD group. No differences were found between the groups in time from diagnosis to surgery. CCD patients had higher rates of low body mass index, anaemia (40.9% vs. 27%, p < 0.001) and low albumin (11.3% vs. 2.6%, p < 0.001). CCD patients had longer operations, lower rates of laparoscopic approach (84.3% vs. 93.1%, p = 0.001) and higher conversion rates (9.3% vs. 1.9%, p < 0.001). CCD patients had a longer hospital stay and higher postoperative complication rates (26.1% vs. 21.3%, p = 0.083). Anastomotic leakage and reoperations were also more frequent in this group. More patients in the CCD group required an extended bowel resection (14.1% vs. 8.3%, p: 0.017). In multivariate analysis, CCD was associated with prolonged surgery (OR 3.44, p = 0.001) and the requirement for multiple intraoperative procedures (OR 8.39, p = 0.030). CONCLUSION: Indication for surgery in patients who present with an inflammatory phenotype of CD was associated with better outcomes compared with patients operated on for complications of the disease. There was no difference between groups in time from diagnosis to surgery.

Background: Colorectal surgery in patients with inflammatory bowel disease (IBD) and cirrhosis has increased morbidity, which may preclude surgery. Preoperative transjugular intrahepatic portosystemic shunt (TIPS) is postulated to reduce surgical risk. In this retrospective single-center study, we characterized perioperative outcomes in patients with IBD and cirrhosis who underwent preoperative TIPS. Methods: We identified patients with IBD and cirrhosis who had undergone preoperative TIPS for portal decompression between 2010 and 2023. All other indications for TIPS led to patient exclusion. Demographic and medical data were collected, including portal pressure measurements. Primary outcome of interest was perioperative outcomes. Results: Ten patients met the inclusion criteria. The most common surgical indications were dysplasia (50%) and refractory IBD (50%). TIPS was performed at a median of 47 days (IQR 34-80) before surgery, with reduction in portal pressures (22.5 vs. 18.5 mmHg, Pâ <â .01) and portosystemic gradient (12.5 vs. 5.5 mmHg, Pâ <â .01). Perioperative complications occurred in 80% of patients, including surgical site bleeding (30%), wound dehiscence (10%), systemic infection (30%), liver function elevation (50%), and coagulopathy (50%). No patients required re-operation, with median length of stay being 7 days (IQR 5.5-9.3). The 30-day readmission rate was 40%, most commonly for infection (75%), with 2 patients having intra-abdominal abscesses and 1 patient with concern for bowel ischemia. Ninety-day and one-year survival was 100% and 90%, respectively. Patients with primary sclerosing cholangitis (PSC)-cirrhosis were noted to have higher perioperative morbidity and a 30-day readmission rate. Conclusions: In patients with IBD and cirrhosis, preoperative TIPS facilitated successful surgical intervention despite heightened risk. Nevertheless, significant complications were noted, in particular for patients with PSC-cirrhosis.
RESUMO
BACKGROUND: The benefits of prophylactic ureteral stent placement during colorectal surgery remain controversial. This study aimed to determine the incidence of ureteral injury in colorectal operations, assess the complications associated with stent usage, and determine whether their use leads to earlier identification and treatment of injury. METHODS: This was a retrospective study of patients undergoing colorectal abdominal operations between 2015 and 2021. Variables were examined for possible association with ureteral stent placement. The primary study endpoint was ureteral injury identified within 30 days postoperatively. RESULTS: Of 6481 patients who underwent colorectal surgery, 970 (15%) underwent preoperative ureteral stent placement. The use of stents was significantly associated with a higher American Society of Anesthesiologists classification, wound classification, and longer duration of surgery. A ureteral injury was identified in 28 patients (0.4%). Of these patients, 13 had no stent, and 15 had preoperative stents placed. After propensity matching, stent use was associated with an increased risk of hematuria and urinary tract infection. Ureteral injury was identified intraoperatively in 14 of 28 patients (50.0%) and was not associated with ureteral stent use (P = .45). CONCLUSION: Iatrogenic ureteral injury was uncommon, whereas preoperative stent placement was relatively frequent. Earlier recognition of iatrogenic ureteral injury is not an expected advantage of preoperative ureteral stent placement.

Secondary amyloidosis (AA) is a disorder of protein conformation associated with inflammatory disorders. Detailed reports of patients diagnosed with AA and inflammatory bowel disease (IBD) are limited. This study reports the cases of eight patients, across three tertiary medical centers, diagnosed with both IBD and AA between 2000 and 2020. Seven patients had a diagnosis of Crohn disease (CD), while one had ulcerative colitis (UC). All patients were diagnosed with AA after being diagnosed with IBD (median: 15 years later). The small bowel (62.5%) and the colon (62.5%) were the most common IBD locations. 4 patients had undergone TNF-alpha inhibitor therapy and all CD patients required surgical treatment of their IBD. A history of fistula or abscess was identified in 5 patients. The most common initial site of AA was the kidney (75%). All 8 patients presented with some form of renal dysfunction and proteinuria (median: 1500 mg/24 h). Hypoalbuminemia was found in most patients. Six patients developed chronic kidney disease and 4 required dialysis. Anti TNF-alpha antibody therapy led to rapid improvement of renal function in one of four patients who received it. Three patients required a renal transplant. Four patients had died upon the latest follow-up (5-year survival: 75%). The presence of proteinuria, fistula, or abscess should serve as indicators for potentially increased AA risk in CD patients.
RESUMO
BACKGROUND: The evolution of enhanced recovery pathways (ERPs) in colon and rectal surgery has led to the development of same-day discharge (SDD) procedures for selected patients. Early discharge after diverting loop ileostomy (DLI) closure was first described in 2003. However, its widespread adoption remains limited, with SDD accounting for only 3.2% of all DLI closures in 2005-2006, according to the American College of Surgeons National Surgical Quality Improvement Program database, and rising to just 4.1% by 2016. This study aimed to compare the outcomes of SDD DLI closure with those of DLI closure after the standard ERP. METHODS: A retrospective case-matched study compared 125 patients undergoing SDD DLI closure with 250 patients undergoing DLI closure after the standard ERP based on age (±1 year), sex, American Society of Anesthesiologists score, body mass index, surgery date (±2 months), underlying disease, and hospital site. The primary outcome was comparative 30-day complication rates. RESULTS: Patients in the traditional ERP group received more intraoperative fluids (1221.1 ± 416.6 vs 1039.0 ± 368.3 mL, P < .001) but had similar estimated blood loss. Ten patients (8%) in the SDD-ERP group failed SDD. The 30-day postoperative complication rate was significantly lower in the SDD group (14.8%) than the standard ERP group (25.7%, P = .025). This difference was primarily driven by a lower incidence of ileus in the SDD group (9.6% vs 14.8%, P = .034). There were no significant differences in readmission rate (9.6% of SDD-ERP vs 9.2% of standard ERP, P = .900) and reoperation rates (3.2% of SDD-ERP vs 2.4% of standard ERP, P = .650). CONCLUSION: SDD ileostomy closure is a safe, feasible, and effective procedure associated with fewer complications than the present study's standard ERP. This could represent a new standard of care. Further prospective trials are required to confirm the findings of this study.

Introduction: Low grade serous ovarian carcinoma (LGSOC) is a rare subtype of ovarian cancer (OC) that is challenging to treat due to its relative chemoresistance. Given that LGSOC patients often recur in the peritoneal cavity, novel intraperitoneal (IP) chemotherapy should be explored. Pressurized intraperitoneal aerosolized chemotherapy (PIPAC) is a method that has demonstrated peritoneal disease control in cancers with peritoneal metastases. Methods: NCT04329494 is a US multicenter phase 1 trial evaluating the safety of PIPAC in recurrent ovarian, uterine, and GI cancers with peritoneal metastases. This analysis describes the outcomes of a sub-cohort of four LGSOC patients treated with IP cisplatin 10.5 mg/m2, doxorubicin 2.1 mg/m2 PIPAC q4-6 weeks. Primary endpoints included dose-limiting toxicities (DLT) and incidence of adverse events (AE). Secondary endpoints were progression free survival (PFS) and treatment response based on radiographic, intraoperative, and pathological findings. Results: Four patients with LGSOC were enrolled of which three were heavily pretreated. Median prior lines of therapy was 5 (range 2-10). Three patients had extraperitoneal metastases, and two patients had baseline partial small bowel obstructive (SBO) symptoms. Median age of patients was 58 (38-68). PIPAC completion rate (≥2 PIPACs) was 75%. No DLTs or Clavien-Dindo surgical complications occurred. No G4/G5 AEs were observed, and one G3 abdominal pain was reported. One patient had a partial response after 3 cycles of PIPAC and completed an additional 3 cycles with compassionate use amendment. Two patients came off study after 2 cycles due to extraperitoneal progressive disease. One patient came off study after 1 cycle due to toxicity. Median decrease in peritoneal carcinomatosis index between cycles 1 and 2 was 5.0%. Ascites decreased in 2 out of 3 patients who had ≥2 PIPACs. Median PFS was 4.3 months (1.7-21.6), median overall survival was 11.6 months (5.4-30.1), and objective response rate was 25%. Conclusion: PIPAC with cisplatin/doxorubicin is well tolerated in LGSOC patients without baseline SBO symptoms. IP response was seen in 2 out of 3 patients that completed ≥2 PIPAC cycles. Further study of PIPAC for patients with recurrent disease limited to the IP cavity and with no partial SBO symptoms should be considered.
