Pancreato-jejunostomy versus hand-sewn closure of the pancreatic stump to prevent pancreatic fistula after distal pancreatectomy: A retrospective analysis

Background: Different methods of pancreatic stump closure after distal pancreatectomy (DP) have been described to decrease the incidence of pancreatic fistula (PF) which still represents one of the most common complications in pancreatic surgery. We retrospectively compared the pancreato-jejunostomy technique with the hand-sewn closure of the pancreatic stump after DP, and analyzed clinical outcomes between the two groups, focusing on PF rate. Methods. Thirty-six patients undergoing open DP at our institution between May 2005 and December 2011 were included. They were divided in two groups depending on pancreatic remnant management: in 24 cases the stump was closed by hand-sewn suture (Group A), while in 12 earlier cases a pancreato-jejunostomy was performed (Group B). We analyzed postoperative data in terms of mortality, morbidity and length of hospital stay between the two groups. Results: PF occurred in 7 of 24 (29.1%) cases of group A (control group) compared to zero fistula rate in group B (anastomosis group) (p=0.005). Operative time was significantly higher in the anastomosis group (p=0.024). Mortality rate was 0% in both groups. Other postoperative outcomes such as hemorrhages, infections, medical complications and length of hospital stay were not significant between the two groups. Conclusion: Despite a higher operative time, the pancreato-jejunostomy after DP seems to be related to a lower incidence of PF compared to the hand-sewn closure of the pancreatic remnant. © 2013 Meniconi et al.; licensee BioMed Central Ltd

Transanal Total Mesorectal Excision: International Registry Results of the First 720 Cases

Objective: This study aims to report short-term clinical and oncological outcomes from the international transanal Total Mesorectal Excision (taTME) registry for benign and malignant rectal pathology. Background: TaTME is the latest minimally invasive transanal technique pioneered to facilitate difficult pelvic dissections. Outcomes have been published from small cohorts, but larger series can further assess the safety and efficacy of taTME in the wider surgical population. Methods: Data were analyzed from 66 registered units in 23 countries. The primary endpoint was "good-quality TME surgery." Secondary endpoints were short-term adverse events. Univariate and multivariate regression analyses were used to identify independent predictors of poor specimen outcome. Results: A total of 720 consecutively registered cases were analyzed comprising 634 patients with rectal cancer and 86 with benign pathology. Approximately, 67% were males with mean BMI 26.5 kg/m 2. Abdominal or perineal conversion was 6.3% and 2.8%, respectively. Intact TME specimens were achieved in 85%, with minor defects in 11% and major defects in 4%. R1 resection rate was 2.7%. Postoperative mortality and morbidity were 0.5% and 32.6% respectively. Risk factors for poor specimen outcome (suboptimal TME specimen, perforation, and/or R1 resection) on multivariate analysis were positive CRM on staging MRI, low rectal tumor <2 cm from anorectal junction, and laparoscopic transabdominal posterior dissection to <4 cm from anal verge. Conclusions: TaTME appears to be an oncologically safe and effective technique for distal mesorectal dissection with acceptable short-term patient outcomes and good specimen quality. Ongoing structured training and the upcoming randomized controlled trials are needed to assess the technique further

Predictive Factors and Risk Model for Positive Circumferential Resection Margin Rate after Transanal Total Mesorectal Excision in 2653 Patients with Rectal Cancer

The aim of this study was to determine the incidence of, and preoperative risk factors for, positive circumferential resection margin (CRM) after transanal total mesorectal excision (TaTME). Background: TaTME has the potential to further reduce the rate of positive CRM for patients with low rectal cancer, thereby improving oncological outcome. Methods: A prospective registry-based study including all cases recorded on the international TaTME registry between July 2014 and January 2018 was performed. Endpoints were the incidence of, and predictive factors for, positive CRM. Univariate and multivariate logistic regressions were performed, and factors for positive CRM were then assessed by formulating a predictive model. Results: In total, 2653 patients undergoing TaTME for rectal cancer were included. The incidence of positive CRM was 107 (4.0%). In multivariate logistic regression analysis, a positive CRM after TaTME was significantly associated with tumors located up to 1 cm from the anorectal junction, anterior tumors, cT4 tumors, extra-mural venous invasion (EMVI), and threatened or involved CRM on baseline MRI (odds ratios 2.09, 1.66, 1.93, 1.94, and 1.72, respectively). The predictive model showed adequate discrimination (area under the receiver-operating characteristic curve &gt;0.70), and predicted a 28% risk of positive CRM if all risk factors were present. Conclusion: Five preoperative tumor-related characteristics had an adverse effect on CRM involvement after TaTME. The predicted risk of positive CRM after TaTME for a specific patient can be calculated preoperatively with the proposed model and may help guide patient selection for optimal treatment and enhance a tailored treatment approach to further optimize oncological outcomes
