Proposal of a new classification system for complete mesocolic excison in right-sided colon cancer.

BACKGROUND: Although complete mesocolic excision has been performed for 10 years there remains no published prospective data. The lack of a classification which includes completeness of mesocolic tissue removal as well as plane of surgery contributes to the problem of comparing studies. The aim of the present study was to develop such a classification for right hemicolectomy. METHODS: In a prospective, non-randomized trial we collected specimens of right hemicolectomies from 38 German hospitals between February 2012 and October 2016. The degree of radicality of resection was reported. Photographs were taken of the specimens. After screening the images it became apparent that the specimens could be divided into four main groups according to the degree of missing mesocolic tissue, and three subgroups reflecting the plane of surgery. RESULTS: Of 1373 patients 1097 images were available. Grading was possible in 1077 (98.2%). Distribution was Type 0 (best) 38.6%, Type I 43.3%, Type II 8.5%, Type III (poorest) 7.8%. Surgery was considered to be in a suboptimal plane of surgery in 15.2% overall, highest in Type III (37%) and lowest in Type 0 (7.8%, p < 0.001). CONCLUSIONS: The proposed classification may be a relevant tool for the further investigation of CME for right colon cancer because it allows us to differentiate the aspects of lymphadenectomy and the preservation of the integrity of the mesocolon.

Effects of Colorectal Surgery Classification on Reported Postoperative Surgical Site Infections.

BACKGROUND: Current procedural terminology (CPT) for colon and rectal surgery lacks procedural granularity and misclassification rates are unknown. However, they are used in performance measurement, for example, in surgical site infection (SSI). The objective of this study was to determine whether American College of Surgeons National Surgical Quality Improvement Program (NSQIP) abstraction methods accurately classify types of colorectal operations and, by extension, reported SSI rates. MATERIALS AND METHODS: This was a retrospective study conducted at a single tertiary care center. The colectomy- and proctectomy-targeted NSQIP database from January 2011 to July 2016 was used to perform a semiautomated reclassification (SAR) of all colectomy and proctectomy cases performed by colorectal surgeons. The primary outcome was the difference in perioperative SSI rates by case classification method. RESULTS: Thousand sixty-three patients underwent a colectomy or proctectomy during the study period with a mean age of 55.7 (SD = 16.7) years. Use of the NSQIP classification scheme resulted in 849 colectomy and 214 proctectomy cases. Use of the SAR method resulted in 650 colectomy cases and 413 proctectomy cases (P < 0.001), a 23.4% reclassification of colectomy cases. The group of cases classified as colectomy by SAR had a lower rate of deep/organ space infections than those classified as colectomy by NSQIP (4.5% versus 7.1%, P = 0.034). CONCLUSIONS: These findings highlight the challenges of CPT code-based patient classification and subsequent outcomes analysis. Expanding the CPT system to more accurately represent colorectal operations would allow for more representative reported outcomes, thus enabling benchmarking and quality improvement.

Review of nomenclature in colonic surgery--proposal of a standardised nomenclature based on mesocolic anatomy.

The standardisation of the surgical management of rectal cancer has been facilitated by adoption of an anatomic surgical nomenclature. Thus, "total mesorectal excision" substituted "anterior resection" or "proctosigmoidectomy" and implies resection of both rectum and mesorectum. Similar trends towards standardisation of colonic surgery are ongoing, yet there remains a heterogeneity of terminology utilised (eg, "right hemicolectomy", "ileocolic resection", and "total mesocolic excision"). Recent descriptions of mesocolic anatomy provide an opportunity to standardise colonic resection according to a more precise and informative anatomic nomenclature. This article aims to firstly emphasise the central importance of the mesocolon and from this propose a related nomenclature for resectional colonic surgery. Introduction of a standardised nomenclature for colonic resection is a necessary step towards standardisation of colonic surgery in general.

Colectomy and the incidence of postsurgical complications among ulcerative colitis patients with private health insurance in the United States.

PURPOSE: We sought to describe the types of colectomy, follow-up surgical/diagnostic procedures, and complications occurring within 180 days of colectomy in a population of privately insured individuals with ulcerative colitis (UC). METHODS: This was a retrospective analysis of claims data of privately insured patients (MarketScan) for the years 2001-2004. We identified a cohort of patients with UC who underwent colectomy. Colectomies were classified into four categories based on the surgery occurring on the first colectomy date: (a) total proctocolectomy (TPC) with ileal pouch-anal anastomosis (IPAA), (b) subtotal colectomy (SC) with ileostomy and Hartmann pouch or ileorectal anastomosis, (c) TPC with ileostomy, and (d) partial colectomy (PC). Follow-up surgical/diagnostic procedures and complications were compared across colectomy categories. RESULTS: A total of 25,586 UC patients were identified, of whom 215 patients had a colectomy and at least 180 days of pre- and postcolectomy follow-up. The colectomy distribution was: TPC-IPAA (52%), SC-ileostomy (22%), TPC-ileostomy (14%), and PC (13%). Within 180 days postcolectomy, 54% of patients had a second colectomy-related surgery (including unplanned surgeries in 15.3%), and 27% had a follow-up diagnostic procedure. Postcolectomy complications included abscesses (11.6% in the first 30 days postcolectomy, 16.3% in the day 31-180 postcolectomy period), fistulas (4.2% early, 6.0% late), and sepsis/pneumonia/bacteremia (7.9% early, 9.3% late). CONCLUSION: Postcolectomy surgical procedures and complications occur frequently after colectomy in privately insured patients with UC.

Defining the rectum: surgically, radiologically and anatomically.

The terminology used in relation to the rectum varies considerably, added to this there is the subjective nature of clinical assessment and variability in the anatomy of the rectum and anus. It is imperative that definitions are clarified and standardized for use by all members of the multidisciplinary team involved in the care of patients with rectal cancer.

Laparoscopic surgery for the cure of colorectal cancer: results of a German five-center study.

PURPOSE: The aim of this study was to assess the feasibility and safety of laparoscopic surgery for the cure of colorectal cancer with emphasis on oncologic follow-up in particular. METHODS: A study was performed of patients with colorectal cancer treated by laparoscopy in five German centers between May 1991 and September 1997. Surgical and pathologic data were recorded in an anonymous registry database and analyzed by type of resection. Standard procedures were sigmoid or left colectomy, anterior resection, abdominoperineal resection, and right hemicolectomy. Follow-up information included incidence of local, distant, and port site recurrence and cancer-related death. RESULTS: A total of 399 patients (212 females) with a mean age of 66.6 years underwent laparoscopic curative resections (sigmoid resection, 89; left colectomy, 11; anterior resection, 157; abdominoperineal resection, 102; right hemicolectomy, 40). Conversion was necessary in 6.3 percent (n = 25). Complications requiring reoperation occurred in 9 percent (n = 35). Complications that were treated conservatively occurred in 27.6 percent (n = 110). Thirty-day mortality was 1.8 percent (n = 7). First bowel movements resumed on the third postoperative day; patients did not use analgesics after a mean of five days. Mean postoperative hospitalization was two weeks. According to International Union Against Cancer classification, 147 patients had Stage I cancer, 35 had Stage II cancer, and 217 underwent curative resection for Stage III cancer. Mean number of lymph nodes resected was 12.1. At a mean follow-up of 30 months, one port site recurrence was documented. No local recurrence was observed after curative resection of Stage I colorectal cancer. Of 399 patients, local recurrence occurred in 6 patients (Stage II, 2; Stage III, 4), and distant metastases were documented in 25 patients (Stage I, 3; Stage II, 3; Stage III, 19). The highest incidence of cancer-related death occurred after abdominoperineal resection (4.9 percent). CONCLUSION: To assess the role of laparoscopic colorectal surgery for the cure of cancer objectively, prospective randomized trials are necessary.

Lavado colonico intra-operatorio en el manejo de emergencias de colon izquierdo / Intraoperative colonic lavage in the management of emergencies of the left colon

El lavado colonico intra-operatorio, es una técnica comprobada y restablecida que garantiza la práctica de una anstomosis primaria de colon ocn razonable seguridad en la cirugía de colon izquierdo de mergencia de casos seleccionados. Con el presente trabajo prospectivo, tratamos de introducir y difundir el conocimiento de dicha técnica en nuestro medio, para su utilizacion rutinaria en todos los casos donde su aplicación esté indicada. El manejo de lesiones de colon izquierdo que requiern una intervención quirúrgica de emergencia, siempre fue motivo de gran controvercia en cuanto a la decisión de realiar una resección colónica con una anastomosis primaria, o de solamente practicar una colostomia temporal para luego , en un segundo tiempo reestablecer el tránsito colónico definitivo. sin embargo un gran número de trabajos individuales realizados en los últimos años, demostraron con un buen resultado, la factibilidad de realizar una resección de colon con anastomosis primaria con la aplicación de un lavado colónico intra-operatorio. Los diveros factores adversos que hacen de una anastomosis primaria sea un anto insegura en colones no preparados, y que posteriormente puedan dar complicaciones post-operatorias serias se resumen en el cuadro N§ 1.
