Clinical and Oncological Impact of a Protective Ileostomy in Rectal Cancer Patients Undergoing Adjuvant Chemotherapy.

Background/aim: During low anterior rectal resection for rectal cancer, a protective ileostomy (PI) is routinely created to reduce the severity of anastomotic complications. The aim of this study was to investigate the side-effects of PI during adjuvant chemotherapy.

Patients And Methods: A retrospective cohort of patients was operated on for non-metastatic rectal cancer with a PI during 2005-2022.

Postoperative rectovaginal fistula: stoma may not be necessary-a French retrospective cohort.

Background: Postoperative rectovaginal fistula leads to a loss of patients' quality of life and presents significant challenges to the surgeon. The literature focusing specifically on postoperative rectovaginal fistulas is limited. The objective of the present study is to identify factors that can enhance the success of the management of this postoperative rectovaginal fistula.

Review of definition and treatment of upper rectal cancer.

While the treatment of locally advanced lower and middle rectal cancer with total mesorectal excision (TME) after neoadjuvant therapy is now well defined, the treatment of locally advanced upper rectal cancer (LAURC) remains controversial. Although most teams and academic societies recommend upfront surgery (US) with partial mesorectal excision (PME), as this appears to be sufficient for these tumors, the literature remains conflicting regarding the additional use of neoadjuvant therapy and TME. Current recommendations for the treatment of LAURC do not reflect actual clinical practice.

Stenosis of the colorectal anastomosis after surgery for diverticulitis: A national retrospective cohort study.

Aim: The aim of this work was to investigate the association between early postoperative anastomotic leakage or pelvic abscess (AL/PA) and symptomatic anastomotic stenosis (SAS) in patients after surgery for left colonic diverticulitis.

Method: This is a retrospective study based on a national cohort of diverticulitis surgery patients carried out by the Association Française de Chirurgie. The assessment was performed using path analyses.

Comparison of a robotic surgery program for rectal cancer: short- and long-term results from a comparative, retrospective study between two laparoscopic and robotic reference centers.

Background: It is assumed that robotic-assisted surgery (RAS) may facilitate complex pelvic dissection for rectal cancer compared to the laparoscopic-assisted resection (LAR). The aim of this study was to compare perioperative morbidity, short- and long-term oncologic, and functional outcomes between the RAS and LAR approaches.

Methods: Between 2015 and 2021, all rectal cancers operated on by (LAR) or (RAS) were retrospectively reviewed in two colorectal surgery centers.

Performance of different nebulizers in clinical use for Pressurized Intraperitoneal Aerosol Chemotherapy (PIPAC).

Objective: Technical ex-vivo comparison of commercial nebulizer nozzles used for Pressurized Intraperitoneal Aerosol Chemotherapy (PIPAC).

Methods: The performance of four different commercial nebulizer nozzles (Nebulizer; HurriChemTM; MCR-4 TOPOL®; QuattroJet) was analysed concerning: i) technical design and principle of operation, ii) operational pressure as function of the liquid flow rate, iii) droplet size distribution via laser diffraction spectrometry, iv) spray cone angle, spray cone form as well as horizontal drug deposition by image-metric analyses and v) chemical resistance via exposing to a cytostatic solution and chemical composition by means of spark optical emission spectral analysis.

Results: The Nebulizer shows quasi an identical technical design and thus also a similar performance (e.

Risk factors for emergency surgery for diverticulitis: A retrospective multicentric French study at 41 hospitals.

Background: The observed increase in the incidence of complicated diverticulitis may lead to the performance of more emergency surgeries. This study aimed to assess the rate and risk factors of emergency surgery for sigmoid diverticulitis.

Method: The primary outcomes were the rate of emergency surgery for sigmoid diverticulitis and its associated risk factors.

Impact of the first wave of COVID-19 epidemy on the surgical management of sigmoid diverticular disease in France: National French retrospective study.

Objective: To analyze the surgical management of sigmoid diverticular disease (SDD) before, during, and after the first containment rules (CR) for the first wave of COVID-19.

Methods: From the French Surgical Association multicenter series, this study included all patients operated on between January 2018 and September 2021. Three groups were compared: A (before CR period: 01/01/18-03/16/20), B (CR period: 03/17/20-05/03/20), and C (post CR period: 05/04/20-09/30/21).

The Angers CT Score is a Risk Factor for the Failure of the Conservative Management of Adhesive Small Bowel Obstruction: A Prospective Observational Multicentric Study.

Background: Identifying the 30% of adhesive small bowel obstructions (aSBO) for which conservative management will require surgery is essential. The association between the previously described radiological score and failure of the conservative management of aSBO remains to be confirmed in a large prospective multicentric cohort. Our aim was to assess the risk factors of failure of the conservative management of aSBO considering the radiological score.

Voltage-Gated Sodium Channel Na1.5 Controls NHE-1-Dependent Invasive Properties in Colon Cancer Cells.

Colorectal cancer (CRC) is the second leading cause of death worldwide, with 0.9 million deaths per year. The metastatic stage of the disease is identified in about 20% of cases at the first diagnosis and is associated with low patient-survival rates.

Safety and Feasibility of High-Pressure/High-Dose Pressurized Intraperitoneal Aerosol Chemotherapy (HP/HD-PIPAC) for Primary and Metastatic Peritoneal Surface Malignancies.

Objective: The aim of this study was to evaluate the feasibility and perioperative safety of high-pressure/high-dose pressurized intraperitoneal aerosol chemotherapy (HP/HD-PIPAC) to manage peritoneal surface malignancies (PSM).

Methods: Retrospective analysis of a prospective database of about 130 consecutive patients scheduled for HP/HD-PIPACs for PSM. Doxorubicin plus cisplatin (PIPAC-C/D) or oxaliplatin (PIPAC-Ox) were nebulized into a constant capnoperitoneum of 20 mmHg at doses of 6, 30, or 120 mg/m of body surface area (BSA).

Prognostic value of primary tumor sidedness in patients with non-metastatic IBD related CRC - Is it the exception to the rule?

Background: Although primary tumor sidedness (PTS) has a known prognostic role in sporadic colorectal cancer (CRC), its role in Inflammatory Bowel Disease related CRC (IBD-CRC) is largely unknown. Thus, we aimed to evaluate the prognostic role of PTS in patients with IBD-CRC.

Methods: All eligible patients with surgically treated, non-metastatic IBD-CRC were retrospectively identified from institutional databases at ten European and Asian academic centers.

Outcomes and Side Effects of Preoperative Chemoradiotherapy for Locally Advanced Upper Rectal Cancer.

Background/aim: The benefit of neoadjuvant (chemo) radiotherapy for locally advanced upper rectal tumors remains controversial. Thus, we aimed to evaluate the outcome of patients with stage II or-III upper rectal cancer undergoing neoadjuvant (chemo) radiotherapy followed by total mesorectal excision in our institution.

Patients And Methods: From April 2004 to October 2019, all patients with stage II or III upper rectal cancer treated with neoadjuvant (chemo) radiotherapy followed by total mesorectal excision were identified from our database.

StomaCare: quality of life impact after enhanced follow-up of ostomy patients by a home healthcare nursing service-a multicentre, randomized, controlled trial.

Aim: A stoma exposes patients to several complications which could impair their quality of life (QoL). In the last decade, the market for stoma therapy in France has evolved, with a significant increase in the activities of home health providers, meeting a need for patient follow-up and companionship. International studies have demonstrated the impact of the stoma therapist (ST) follow-up on the improvement of an ostomy patient's QoL.

Development and technical validation of an ultrasound nebulizer to deliver intraperitoneal pressurized aerosols in a rat colon cancer peritoneal metastases model.

Background/aim: To develop and validate a nebulizer device for anti-cancer research on pressurized intraperitoneal aerosol supply in a preclinical peritoneal metastases (PM) rat model.

Material And Methods: For aerosol generation, an ultrasonic nebulizer (USN) was modified. Aerosol analyses were performed ex-vivo by laser diffraction spectrometry (LDS).

Role of protective stoma after primary anastomosis for generalized peritonitis due to perforated diverticulitis-DIVERTI 2 (a prospective multicenter randomized trial): rationale and design (nct04604730).

Background: Traditionally, patients with peritonitis Hinchey III and IV due to perforated diverticulitis were treated with Hartmann's procedure. In the past decade, resection and primary anastomosis have gained popularity over Hartmann's procedure and recent guidelines recommend Hartmann's procedure in two situations only: critically ill patients and in selected patients with multiple comorbidity (at high risk of complications). The protective stoma (PS) is recommended after resection with primary anastomosis, however its interest has never been studied.
