Background: Advances in cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) and pressurized intraperitoneal aerosol chemotherapy (PIPAC) have improved outcomes for selected patients with peritoneal surface malignancies (PSMs). Methods: This retrospective study analyzed 743 PSM patients treated at Fondazione Policlinico Universitario Agostino Gemelli from January 2016 to February 2024. The primary aim was to assess median overall survival (mOS), median disease-free survival (mDFS), and median progression-free survival (mPFS) stratified by tumor origin. Secondary outcomes examined the role of diagnostic laparoscopy in the management of PSMs and intra- and postoperative complications’ rates. Results: A total of 1113 procedures were performed: 389 CRS, 370 PIPAC, and 354 diagnostic laparoscopies. Colorectal cancer was the predominant indication for CRS (52.4%), with a mOS of 52 months and mDFS of 22 months. Patients affected by gastric cancer undergoing CRS had a mOS of 18 months and a mDFS of 13 months, while PIPAC yielded a mOS of 9 months and a mPFS of 4 months. Among patients with pseudomyxoma peritonei undergoing CRS, the 5-year DFS rate was 64.1%, and OS rate was 89%. Patients affected by mesothelioma and treated with CRS exhibited a median OS of 43 months and a DFS of 26 months. Pancreatic and hepatobiliary cancers were treated with PIPAC, with a respective mOS of 12 and 8 months. Postoperative complications occurred in 12.6% of CRS, 3.2% of PIPAC, and 1.7% of diagnostic laparoscopies. High peritoneal cancer index (PCI), gastric resection, and blood loss over 500 mL were identified as risk factors for major complications in a multivariate analysis. Conclusions: Developing a highly experienced multidisciplinary team is crucial for delivering tailored treatment strategies which aim to achieve optimal oncological outcomes while preserving patients’ quality of life.
To assess the risk perception and the uptake of measures preventing environment-related risks in the operating room (OR) during hyperthermic intraperitoneal chemotherapy (HIPEC) and pressurized intraperitoneal aerosol chemotherapy (PIPAC). A multicentric, international survey among OR teams in high-volume HIPEC and PIPAC centers: Surgeons (Surg), Scrub nurses (ScrubN), Anesthesiologists (Anest), Anesthesiology nurses (AnesthN), and OR Cleaning staff (CleanS). Scores extended from 0-10 (maximum). Ten centers in six countries participated in the study (response rate 100%). Two hundred and eleven responses from 68 Surg (32%), 49 ScrubN (23%), 45 Anest (21%), 31 AnesthN (15%), and 18 CleanS (9%) were gathered. Individual uptake of protection measures was 51.4%, similar among professions and between HIPEC and PIPAC. Perceived levels of protection were 7.57 vs. 7.17 for PIPAC and HIPEC, respectively (p<0.05), with Anesth scoring the lowest (6.81). Perceived contamination risk was 4.19 for HIPEC vs. 3.5 for PIPAC (p<0.01). Information level was lower for CleanS and Anesth for HIPEC and PIPAC procedures compared to all other responders (6.48 vs. 4.86, and 6.48 vs. 5.67, p<0.01). Willingness to obtain more information was 86%, the highest among CleanS (94%). Experience with the current practice of safety protocols was similar during HIPEC and PIPAC. The individual uptake of protection measures was rather low. The safety perception was better for PIPAC, but the perceived level of protection remained relatively low. The willingness to obtain more information was high. Intensified, standardized training of all OR team members involved in HIPEC and PIPAC is meaningful.
Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has gained increasing acceptance in clinical practice. Performing CRS and HIPEC laparoscopically represents a challenging and intriguing technical evolution. However, the experiences are limited, and the evidence is low. This retrospective analysis was performed on patients treated with laparoscopic CRS-HIPEC within the Italian Peritoneal Surface Malignancies Oncoteam. Clinical, perioperative, and follow-up data were extracted and collected on prospectively maintained databases. We added a systematic review according to the PRISMA method for English-language articles through April 2022 using the keywords laparoscopic, hyperthermic, HIPEC, and chemotherapy. From 2016 to 2022, fourteen patients were treated with Lap-CRS-HIPEC with curative intent within the Italian centers. No conversion to open was observed. The median duration of surgery was 487.5 min. The median Peritoneal Cancer Index (PCI) was 3, and complete cytoreduction was achieved in all patients. Two patients (14.3%) had major postoperative complications, one requiring reintervention. After a median follow-up of 16.9 months, eleven patients were alive without disease (78.6%), two patients developed recurrence (14.3%), and one patient died for unrelated causes (7.1%). The literature review confirmed these results. In conclusion, current evidence shows that Lap-CRS-HIPEC is feasible, safe, and associated with a favorable outcome in selected patients. An accurate patient selection will continue to be paramount in choosing this treatment.
A trend toward avoidance of a defunctioning colostomy at emergency large-bowel surgery has been placed in recent years. The surgical management of patients with acute colonic disease has been evolving from multiple to single operations with a reduced use of colostomy.One hundred four consecutive non-selected patients underwent surgery for left-sided large bowel emergencies between 1980-2003. Defunctioning colostomy was performed in 10 out of 58 resection-anastomosis procedures. Thirty-seven patients underwent Hartmann procedure, 9 received only diverting colostomy. Postoperative morbidity was 28.8%. Postoperative mortality 8.2%. Anastomotic leak occurred in 1 and 6 patients with and without defunctioning colostomy respectively. Four out of the 6 patients without colostomy needed reintervention, while patient with covering colostomy underwent conservative treatment. Six (10.5%) out 56 patients with colostomy experienced major stoma related complications and underwent reintervention.Although there is general acceptance of one-stage surgery for right-sided colon emergencies, the surgical management of left-side large bowel obstruction and peritonitis remains controversal. Risk of anastomotic dehiscence associated with large-bowel anastomosis in unfavourable circumstance must be balanced against the high complications and low closure rates of a temporary colostomy.Primary resection and anastomosis without diverting colostomy for left-sided acute obstruction and peritonitis may be performed in selected patients. Diffuse purulent and faecal peritonitis are contraindications to one-stage surgery being necessary a two- stage procedure with loop or end colostomy. Colostomy remain a valid surgical option when high risk of dehiscence is suspected.
Ultrasound appearance of intragallbladder haemorrhage in two patients with haemobilia is presented. Gallbladder lumina were occupied by non-shadowing, firm masses of mixed echogenicity representing blood clots. In both cases iatrogenic trauma following percutaneous transcholecystic cholangiography and blind hepatic biopsy caused bleeding in the biliary tree.
Introduction: Patients with peritoneal metastasis frequently develop malignant bowel obstruction (MBO). Medical palliative management is preferred but often fails. Conversely, the role of palliative surgery remains unclear and debated. This study aims to identify patients who could benefit from invasive surgical interventions and factors associated with successful surgical palliation. Materials and Methods: In this retrospective study, 98 consecutive patients who underwent palliative surgery for MBO over 5 years were reviewed. We evaluate as the primary outcome surgical failure to select patients who could benefit from palliative surgery, avoiding unnecessary surgery. A prognostic score was developed based on a logistic regression model to identify patients at risk of surgical failure. The score was evaluated for overall accuracy by receiver operating characteristic curve analysis. Results: Palliative surgery was achieved in 76 (77.5%) patients. The variables that were found to be significant factors for surgical failure are recurrent disease (P = 0.015), absence of bowel obstruction (P < 0.001), absence of bowel distension (P < 0.001), and mesenteric involvement (P = 0.001) and retraction (P < 0.001). The absence of bowel distension (P = 0.046) and bowel obstruction (P = 0.012) emerged as independent predictors of surgical failure. Carcinomatosis level assessment for peritoneum score, based on these factors, was built to evaluate the risk of surgical failure. Conclusion: Our proposed scoring system might help select patients most likely to benefit from palliative surgery.
