Transanal Endoscopic Operation for Benign Rectal Lesions and T1 Carcinoma.

BACKGROUND AND OBJECTIVES: Transanal endoscopic operation (TEO) is a minimally invasive technique used for local excision of benign and selected malignant rectal lesions. The purpose of this study was to investigate the feasibility, safety, and oncological outcomes of the procedure and to report the experience in 3 centers. METHODS: Retrospective review of a prospectively collected database was performed of all patients with benign lesions or ≤cT1N0 rectal cancer who underwent TEO with curative intent at 3 Belgian centers (2012 through 2014). RESULTS: Eighty-three patients underwent 84 TEOs for 89 rectal lesions (37 adenomas, 43 adenocarcinomas, 1 gastrointestinal stromal tumor, 1 lipoma, 2 neuroendocrine tumors, and 5 scar tissues). Operative time was associated with lesion size (P < .001). Postoperative complications occurred in 13 patients: 7 hemorrhages, 1 urinary tract infection, 1 urinary retention, 2 abscesses, 1 anastomotic stenosis, and 1 entrance into the peritoneal cavity. Median hospital stay was 3 days (range, 1-8). During a median follow-up of 13 months (range, 2-27), there was 1 recurrence. CONCLUSION: Although longer follow-up is still necessary, TEO appears to be an effective method of excising benign tumors and low-risk T1 carcinomas of the rectum. However, TEO should be considered as part of the diagnostic work-up. Furthermore, the resected specimen of a TEO procedure allows adequate local staging in contrast to an endoscopic piecemeal excision. Nevertheless, definitive histology must be appreciated, and in case of unfavorable histology, radical salvage resection still has to be performed.

Central mesh failure after laparoscopic IPOM procedure.

Central mesh failure after laparoscopic repair of a ventral hernia is a rare finding. We present a case of a 42-year-old man with clear umbilical hernia recurrence 4 years after IPOM procedure with an oxidized cellulose composite polypropylene mesh, using the double crown technique. Laparoscopy showed that a segment of small intestine herniated through a central defect in the prosthesis. A primary repair of the umbilical hernia recurrence was performed through a small transverse infraumbilical incision suturing both the fascia and mesh with interrupted non-resorbable monofilament sutures. A plausible explanation for this type of recurrence might be that the center of the mesh was further torn after an initial (micro) trauma induced by the tackers used for fixation.

Risk adjusted benchmarking of abdominoperineal excision for rectal adenocarcinoma in the context of the Belgian PROCARE improvement project.

OBJECTIVE: The abdominoperineal excision (APE) rate, a quality of care indicator in rectal cancer surgery, has been criticised if not adjusted for confounding factors. This study evaluates variability in APE rate between centres participating in PROCARE, a Belgian improvement initiative, before and after risk adjustment. It also explores the effect of merging the Hartmann resections (HR) rate with that of APE on benchmarking. DESIGN: Data of 3197 patients who underwent elective radical resection for invasive rectal adenocarcinoma up to 15 cm were registered between January 2006 and March 2011 by 59 centres, each with at least 10 patients in the registry. Variability of APE or merged APE/HR rates between centres was analysed before and after adjustment for gender, age, ASA score (3 or more), tumour level (rectal third), depth of tumour invasion (cT4) and preoperative incontinence. RESULTS: The overall APE rate was 21.1% (95% CI 19.7 to 22.5%). Significant variation of the APE rate was observed before and after risk adjustment (p<0.0001). For cancers in the lower rectal third, the overall APE rate increased to 45.8% (95% CI 43.1 to 48.5%). Also, variation between centres increased. Risk adjustment influenced the identification of outliers. HR was performed in only 2.6% of patients. However, merging of risk adjusted APE and HR rates identified other centres with outlying definitive colostomy rates than APE rate alone. CONCLUSION: Significant variation of the APE rate was observed. Adjustment for confounding factors as well as merging HR with APE rates were found to be important for the assessment of performances.

Exploring limits for data registration in the context of PROCARE, a quality improvement project on rectal cancer.

BACKGROUND: A high burden of registration in the context of quality improvement projects may result in registration fatigue. METHODS: Time required for data collection and registration was measured. Quality of care indicators (QCI) were scored and factors for adjusted benchmarking were identified. The PROCARE data set was compared with 5 other European data sets. RESULTS: Time required for data collection varied per domain while time for registration was more uniform. On average, per item 33 seconds were needed for collection and registration. The number of data to be registered per patient was 48-276, depending on the stage of the disease, resulting in a minimum of 25 minutes and a maximum of 2 hours 4 minutes per patient, follow-up not included. Focusing on 43 clinically relevant QCIs would result in a 50% reduction, using aggregate scores for performance audit in a 71% reduction. The PROCARE data set was larger than comparable European data sets. Linkage of the PROCARE database with administrative databases provided confident data on the patients' survival status, but did not appear to be a practical option for other QCIs. CONCLUSIONS: Limiting the aim to performance audit could significantly reduce the burden of registration. In the context of a quality improvement project, the PROCARE Steering Group concluded that detailed clinical data from all centres are still required, which can be reconsidered in the future. Maintenance of a specific database remains of crucial value. Data collection and registration cannot be based on benevolence but should be compensated for.
