Risk factors for severe morbidity and definitive stoma after elective surgery for sigmoid diverticulitis: a multicenter national cohort study.

BACKGROUND: In the decision to perform elective surgery, it is of great interest to have data about the outcomes of surgery to individualize patients who could safely undergo sigmoid resection. The aim of this study was to provide information on the outcomes of elective sigmoid resection for sigmoid diverticular disease (SDD) at a national level. METHODS: All consecutive patients who had elective surgery for SDD (2010-2021) were included in this retrospective, multicenter, cohort study. Patients were identified from institutional review board-approved databases in French member centers of the French Surgical Association. The endpoints of the study were the early and the long-term postoperative outcomes and an evaluation of the risk factors for 90-day severe postoperative morbidity and a definitive stoma after an elective sigmoidectomy for SDD. RESULTS: In total, 4617 patients were included. The median [IQR] age was 61 [18.0;100] years, the mean ± SD body mass index (BMI) was 26.8 ± 4 kg/m2, and 2310 (50%) were men. The indications for surgery were complicated diverticulitis in 50% and smoldering diverticulitis in 47.4%. The procedures were performed laparoscopically for 88% and with an anastomosis for 83.8%. The severe complication rate on postoperative day 90 was 11.7%, with a risk of anastomotic leakage of 4.7%. The independent risk factors in multivariate analysis were an American Society of Anesthesiologists (ASA) score ≥ 3, an open approach, and perioperative blood transfusion. Age, perioperative blood transfusion, and Hartmann's procedure were the three independent risk factors for a permanent stoma. CONCLUSIONS: This series provides a real-life picture of elective sigmoidectomy for SDD at a national level. TRIAL REGISTRATION: Comité National Information et Liberté (CNIL) (n°920361).

Delayed coloanal anastomosis: an alternative option for restorative rectal cancer surgery after high-dose pelvic radiotherapy for prostate cancer.

AIM: Restorative total mesorectal excision (TME) for rectal cancer after high-dose pelvic radiotherapy for prostate cancer has been reported to provide an unacceptable rate of pelvic sepsis. In a previous publication we proposed that delayed coloanal anastomosis (DCAA) should be performed in this situation. The present study aimed to assess the feasibility and outcomes of this strategy. METHOD: Between 2000 and 2018, 1094 men were operated on for rectal cancer in our institution. All men with T2/T3 mid and low rectal cancer with preoperative radiotherapy and restorative TME were considered for this study (n = 416). Patients with external-beam high-dose radiotherapy (EBHRT) for prostate cancer (70-78 Gy) were identified and compared with patients with conventional long-course chemoradiotherapy (CRT) followed by TME. We compared our already published historical cohort (2000-2012), including arm A (CRT + TME; n = 236) and arm B (EBHRT + TME; n = 12), with our early cohort (2013-2018), including arm C (CRT + TME; n = 158) and arm D (EBHRT + TME-DCAA; n = 10). The end-points were morbidity, pelvic sepsis, reoperation rate and quality of the specimen. RESULTS: Overall morbidity was not significantly different between groups. Pelvic sepsis decreased from 50% (arm B) to 10% (arm D) with the use of DCAA (P = 0.074), and was similar between arms A, C and D. Quality of the specimen was not significantly different between the four groups. CONCLUSION: Our results suggest that TME with DCAA in patients with previous EBHRT is feasible, with the same postoperative pelvic sepsis rate as conventional CRT.

Perioperative antibiotherapy should replace prophylactic antibiotics in patients undergoing pancreaticoduodenectomy preceded by preoperative biliary drainage.

BACKGROUND AND OBJECTIVES: Pancreaticoduodenectomy (PD) remains a morbid surgery. Preoperative biliary drainage (PBD) is often necessary before surgery but is associated with biliary contamination. We compared the postoperative complications of patients undergoing PBD who received the usual prophylactic antibiotics (PAs) or systematic antibiotherapy (ABT). METHODS: All patients who underwent surgery between 2008 and 2017 were included. Systematic perioperative ABT with piperacillin + tazobactam (ABT group) was implemented in 2014 as the standard of care for PBD. Patients treated in the period before such implementation, during which standard cefazolin was given, served as the controls (PAs group). The primary outcomes were postoperative complications. RESULTS: We included 122 patients with PBD who underwent surgery. There were no demographic differences between the two groups. Perioperative ABT was associated with a reduction in deep abdominal abscesses (36% vs 10%, P = .0008), respiratory tract infections (15% vs 3%; P = .02), bacteremia (41% vs 6%; P < .0001), and a shorter length of hospital stay (17 [13-27] vs 13 [10-14] days; P < .0001). ABT was a protective factor against the development of deep abdominal abscesses (odds ratio [OR] = 0.16; P = .001) whereas smoking (OR = 3.9) and pancreatic fistula (OR = 19.1) were risk factors. CONCLUSION: Systematic perioperative ABT in patients undergoing PD preceded by PBD may reduce deep surgical infections and the length of hospital stay.

Multidisciplinary meetings specific to hepatocellular carcinoma: How to proceed?

The French "cancer plan" has created a framework for good practice in the course of care for cancer patients. Decisions must be made in a multidisciplinary team meeting (MDM) and an individualized care plan (ICP) is to be established for each patient. Hepatocellular carcinoma (HCC) is a common cancer with complex treatments that warrant a dedicated meeting. Cancer coordination centers (3C) ensure the organization and the functioning of MDMs. Multidisciplinary, standardized and systematic assessment of HCC patients allows for personalized management and orients them toward treatment that is either curative (transplantation, surgical resection, ablathermy) or palliative (chemoembolization, radiotherapy, systemic treatment, supportive care). MDMs bring together all the professionals treating the disease, and who are tasked with producing an enforceable document effective that justifies decisions and is often an essential step towardinclusion of patients in a clinical trial. It must be carried out according to a systematic schema in an approach applied from initial diagnosis to treatment outset and throughout the treatment. Numerous advances in HCC treatments have rendered their management complex, with the possibility of liver transplantation, twhose access is regulated by the Biomedicine Agency requiring the submission of MDM reports. MDMs must meet specific quality criteria to ensure effective management based on general guidelines and yet specifically tailored to each patient.

Surgery for rectal cancer after high-dose radiotherapy for prostate cancer: is sphincter preservation relevant?

AIM: The feasibility and outcome of sphincter-saving resection for rectal cancer were assessed in patients previously treated by high-dose radiotherapy for prostate cancer. METHOD: Between 2000 and 2012, 1066 patients underwent rectal excision for rectal cancer. Of these, 236 were treated by conventional radiotherapy (45 Gy) and sphincter-saving resection (Group A) and 12 were treated by external-beam radiotherapy (EBRT) for prostate cancer (70 Gy) and sphincter-saving resection (Group B) of whom five had a metachronous and seven a synchronous cancer. The end-points were surgical morbidity, pelvic sepsis, reoperation and definitive stoma. RESULTS: Tumour characteristics were similar in both groups. Surgical morbidity (67% vs 25%, P = 0.004), anastomotic leakage (50% vs 10%, P = 0.001, and reoperation (50% vs 17%, P = 0.011) were significantly higher in Group B. Multivariate analyses showed that EBRT for prostate cancer was the only independent factor for anastomotic leakage (OR = 5.12; 95% CI 1.45-18.08; P = 0.011) and definitive stoma (OR = 10.56; 95% CI 3.02-39.92; P < 0.001). CONCLUSION: High-dose radiotherapy for prostate cancer increases morbidity from rectal surgery and the risk of a permanent stoma. This suggests that a delayed coloanal anastomosis or a Hartmann procedure should be proposed as an alternative to low anterior resection in this population.

Short- and long-term impact of body mass index on laparoscopic rectal cancer surgery.

AIM: Obesity is associated with increased technical difficulty in laparoscopic surgery. However, its impact has been measured mainly for colectomy but not specifically for rectal excision. The aim of the study was to assess the impact of body mass index (BMI) on technical feasibility and oncological outcome of laparoscopic rectal excision for cancer. METHOD: A total of 490 patients treated by laparoscopic rectal excision for rectal cancer from January 1999 to June 2010 were included. Seventy per cent had had preoperative radiochemotherapy. Patients were separated into four groups according to BMI (kg/m(2) ): < 20, 20-25, 25-30 and ≥ 30. The impact of BMI on conversion, surgical morbidity, quality of excision (Quirke mesorectal grade and circumferential resection margin) and long-term oncological outcome was determined. RESULTS: Among the 490 patients BMI was < 20 in 43, 20-25 in 223, 25-30 in 177 and ≥ 30 in 47. Mortality (overall 1%) and morbidity (overall 19%) were similar between the groups. Conversion in the four groups was 5%, 14%, 23% and 32% (P = 0.001). The quality of mesorectal excision and circumferential margins did not differ between the groups. The 5-year local recurrence rates (0%, 4.6%, 5.3% and 5.9% respectively; P = 0.823) and the overall and disease-free survival were not significantly influenced by BMI. CONCLUSION: In laparoscopic surgery for rectal cancer, BMI influenced the risk of conversion but not surgical morbidity, quality of surgery and survival. This suggests that all patients, including obese patients, are suitable for laparoscopic surgery.
