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. However, the impact of home stoma nurse management has not been analysed. In this context we would like to assess the added value on health-related QoL from the enhanced follow-up of ostomy patients by STs. METHODS: This is a randomized, controlled, open, national and multicentre trial (12 centres) which includes patients with an ostomy who benefit from either standard follow-up or from an enhanced and personalized follow-up with, in particular, regular consultations with an ST after discharge. The primary end-point is the 3-month QoL score obtained from the Stoma-QoL questionnaire. The secondary end-points are satisfaction of the care, comparison of QoL scores (Stoma-QoL and EuroQuol EQ-5D) and the economic gains by calculating the consumption of resources between the two arms. There will be a modified intention-to-treat analysis with 6-month follow-up in both study arms. DISCUSSION: The StomaCare trial will be the first randomized controlled study in France to evaluate the impact on QoL of an enhanced follow-up at home of ostomy patients by an ST.

Perineal or Abdominal Approach First During Intersphincteric Resection for Low Rectal Cancer: Which Is the Best Strategy?

BACKGROUND: Intersphincteric resection during total mesorectal excision for low rectal cancer can be performed through a primary abdominal or a primary perineal approach. OBJECTIVE: The purpose of this study was to compare the results of a primary perineal approach with those of a primary abdominal approach in patients undergoing laparoscopic total mesorectal excision for low rectal cancer. DESIGN: This was a case-matched retrospective study from a prospectively maintained database. SETTING: The study was conducted at a tertiary colorectal surgery referral center. PATIENTS: From 2005 to 2013, among 138 patients with low rectal cancer who underwent total mesorectal excision with intersphincteric resection, 34 patients with a primary abdominal approach (abdominal group) were matched with 51 identical patients with a primary perineal approach (6-cm perineal dissection along the mesorectal plane; perineal group), according to TNM stage, sex, BMI, and age. MAIN OUTCOMES MEASURES: Postoperative morbidity, oncologic outcomes, and 3-year overall and disease-free survivals were measured. RESULTS: The operative time was significantly shorter in the perineal group (269 minutes in perineal vs 240 minutes in abdominal group; p = 0.01). Overall morbidity (47% vs 47%; p = 1.00), severe morbidity (16% vs 15%; p = 0.90), and clinical anastomotic leakage (24% vs 12%; p = 0.17) rates showed no differences when comparing the 2 groups. The overall R1 resection rate was similar in the 2 groups (16% vs 9%; p = 0.36), including a 10% vs 9% positive circumferential margin (p = 0.88) and a 8% vs 0% positive distal margin (p = 0.15). After a median follow-up of 39 months, 3-year overall (100% vs 93% (95% CI, 88%-98%); p = 0.26) and disease-free (63% (95% CI, 56%-71%) vs 62% (95% CI, 53%-71%); p = 0.58) survival rates showed no differences between the 2 groups. LIMITATIONS: The study was limited by its nonrandomized nature and limited sample size. CONCLUSIONS: In cases of laparoscopic total mesorectal excision with intersphincteric resection for low rectal cancer, the primary perineal approach appears to reduce operative time and is associated with similar short- and long-term outcomes as compared with the primary abdominal approach. The primary perineal approach should thus be considered as the standard strategy.

Risk factors for circumferential R1 resection after neoadjuvant radiochemotherapy and laparoscopic total mesorectal excision: a study in 233 consecutive patients with mid or low rectal cancer.

PURPOSE: This study aimed to identify risk factors for circumferential R1 resection (R1c) after neoadjuvant radiochemotherapy (RCT) and laparoscopic total mesorectal excision (TME) for mid or low rectal cancer. Better knowledge of pre- or intraoperative risk factors could possibly help for the management of these patients. METHODS: Between 2005 and 2013, 233 consecutive patients undergoing laparoscopic TME for low or mid rectal cancer after RCT were included. R1c resection was defined as a circumferential margin ≤ 1 mm. Univariate and multivariate analyses were performed to identify independent risk factors for R1c. RESULTS: Twenty-five patients had R1c resection (11%). In univariate analysis, low rectal cancer, anterior tumour, T4 on pretherapeutic magnetic resonance imaging (MRI), T4 and/or N+ on post-RCT MRI and operative time > 240 min were associated with a significantly increased risk of R1c resection. In multivariate analysis, only T4 on post-RCT MRI (odds ratio (OR) = 6.02 [1.06-33]; p = 0.043) and operative time >240 min. (OR = 5.4 [1.01-28.9]; p = 0.049) were identified as independent risk factors for R1c resection. The risk of R1c resection was 3% (n = 3/88), 10% (n = 5/51) or 38% (n = 3/8) when 0, 1 or 2 risk factors were present in the same patient, respectively. CONCLUSION: Patients with T4 on MRI after RCT and/or operative time >240 min. seems to be at higher risk for R1c resection. In a pragmatic approach, we consider that systematic second MRI after RCT could help the surgeon, especially in area where circumferential margin is too short, in order to reduce this risk of R1 resection.

Toward the end of abdominoperineal resection for rectal cancer? An 8-year experience in 189 consecutive patients with low rectal cancer.

OBJECTIVES: To assess whether recent advances, such as intersphincteric resection (ISR) or local excision (LE) if a suspicion of complete tumor response after radiochemotherapy (RCT), could have modified the rate of end stoma (ES) in low rectal cancer treatment. BACKGROUND: ES rate remains around 30% to 50% in patients with low rectal cancer. METHODS: From 2005 to 2013, all patients with low rectal cancer undergoing laparoscopic total mesorectal excision, with or without neoadjuvant RCT, and patients undergoing LE after RCT were included. RESULTS: A total of 189 patients presented a low rectal cancer; 162 (86%) underwent RCT; total mesorectal excision was performed in 172 (90%), followed by stapled colorectal anastomosis (n=26; 15%), manual coloanal anastomosis with partial (n=92; 53%) or total ISR (n=32; 19%), or ES that included abdominoperineal resection (n=21; 12%) and low Hartmann procedure (n=1; 1%). LE after RCT was performed in 19 of 189 (10%) patients with a suspicion of complete tumor response. Among them 2 of 19 (11%) underwent immediate secondary total mesorectal excision (1 abdominoperineal resection and 1 coloanal anastomosis with total ISR) because of poor pathological criteria. CONCLUSIONS: Management of rectal cancer with colorectal anastomosis and coloanal anastomosis with partial ISR allowed to obtain a 38% ES rate (71/189); the additional use of total ISR decreased this rate to 22% (39/189). Selective use of LE reduced this rate to only 12% (22/189). Nowadays, recent advances lead to a paradigm shift, with only 12% ES rate in low rectal cancer.

Hyperthermic intraperitoneal chemotherapy in ovarian cancer: an update.

In the treatment of advanced-stage epithelial ovarian cancer (EOC)-associated surgery and chemotherapy with intravenous platinum/taxane-based therapy most patients had early or late recurrence. Prevention of progression and recurrence is a major objective for the management of EOC. Recently, many clinical studies have evaluated the strategy with hyperthermic intraoperative intraperitoneal (IP) drug delivery. This is an update of hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC) in EOC and a view for future strategies. Until recently studies on HIPEC in patients with EOC were mostly retrospective and heterogeneous. Thanks to recent clinical trials, it is reasonable to conclude that surgical cytoreduction and HIPEC is an interesting approach in the management of EOC without increasing morbidity.

Partial Mesorectal Excision for Rectal Adenocarcinoma: Morbidity and Oncological Outcome.

INTRODUCTION: The surgical approach for the treatment of tumors of the upper third of the rectum remains controversial. Several publications have shown that partial excision of the mesorectum (PME) with division of the mesorectum and rectum 5 cm below the tumor could be a reasonable approach although total mesorectal excision (TME) is still considered the gold standard for all rectal cancers in many studies. We aimed to assess the specifics risks of anterior resection with PME and colorectal anastomosis (CRA) in rectal cancer. PATIENTS AND METHODS: Files of all of the patients who underwent a PME between 2000 and 2011 were reviewed in consecutive order. Complications that occurred within 3 months after surgery, oncological outcome, local and distant recurrences, and survival were assessed. RESULTS: One hundred seventy-two patients had a PME with CRA of whom 49 (28.5%) had a dysfunctional stoma. Grade III to IV complications occurred in 18 (10.5%) patients and 2 (1.2%) died. Thirteen (7.6%) developed an anastomotic leakage, and 5 (2.9%) resulted with a permanent stoma. Mean follow-up was 151 months (range, 0-151 months). The 5-year local recurrence rate was 5.3%. The 5-year overall and disease-free survival assessed in the 147 patients without synchronous metastasis were 93.2% and 79.7%, respectively. CONCLUSION: Partial excision of the mesorectum can be performed safely, in 1 stage in many patients, with a low risk of definitive stoma. The local recurrence and the survival rates that we observed indicate that the prognosis is not altered compared with TME. Therefore, PME can be recommended in the treatment of upper and some mid rectal tumors.

Volumetric Portal Embolization: A New Concept to Improve Liver Regeneration and Hepatocyte Engraftment.

BACKGROUND: Hepatocyte transplantation has been proposed as an alternative to orthotopic liver transplantation to treat metabolic liver diseases. This approach requires preconditioning of the host liver to enhance engraftment of transplanted hepatocytes. Different methods are currently used in preclinical models: partial hepatectomy, portal ligature or embolization, and radiotherapy or chemotherapeutic drugs. However, these methods carry high risks of complications and are problematic for use in clinical practice. Here, we developed an innovative method called volumetric (distal, partial, and random) portal embolization (VPE), which preserves total liver volume. METHODS: Embolization was performed in the portal trunk of C57BL6 adult mice with polyester microspheres, to ensure a bilateral and distal distribution. The repartition of microspheres was studied by angiographic and histological analyses. Liver regeneration was evaluated by Ki67 labeling. Optimal conditions for VPE were determined, and the resulting regeneration was compared with that after partial hepatectomy (70%). Labeled adult hepatocytes were then transplanted, and engraftment was compared between embolized (n = 19) and nonembolized mice (n = 8). Engraftment was assessed in vivo and histologically by tracking labeled cells at day 5. RESULTS: The best volumetric embolization conditions, which resulted in the regeneration of 5% of total liver, were 8 × 10 ten-micron microspheres infused with a 29 G needle directly into the portal trunk at 3.3 µL/s. In these conditions, transplanted hepatocytes engraftment was significantly higher than that in control conditions (3 vs 0.65%). CONCLUSIONS: The VPE is a new, minimally invasive, and efficient technique to prepare the host liver for cell transplantation.

Diaphragmatic necrosis after radiofrequency ablation of hepatocellular carcinoma: a successful surgical repair.

We report a case of complete hemidiaphragmatic necrosis with liver abscess complicating radiofrequency ablation of a large subdiaphragmatic hepatocellular carcinoma in a patient with unrecognized history of endoscopic oddi sphincterotomy. At 2-year follow-up after surgical repair using a pedicled latissimus dorsi flap, clinical examination and imaging did not show complication or cancer recurrence. The risk of complete hemidiaphragmatic necrosis resulting from both thermal and septic injuries should be considered when radiofrequency ablation is performed for liver dome tumors, particularly in patients with impaired oddi sphincter. In this septic situation, a latissimus dorsi flap appears as the unique opportunity to repair the injured hemidiaphragm.
