Laparoscopic Extended Right Colectomy
Springer Surgery Atlas Series, 2019Co-Authors: Skandan Shanmugan, Conor P DelaneyAbstract:Laparoscopic Colectomy is now the standard of care for suitable patients when an appropriately trained surgeon is available. Right hemiColectomy lends itself to a very standardised, reproducible technique that is relatively easily learned and is based on sound oncological principles. An extended right Colectomy, whether for benign or malignant indications complicates the procedure, as mobilisation of the middle colic vessels is required. Our approach to extended right Colectomy is discussed here, emphasizing a structured, stepwise approach that works easily in most clinical situations and permits a successful laparoscopic approach in almost all patients.

Laparoscopic Technique for Right Colectomy
Surgery for Cancers of the Gastrointestinal Tract, 2014Co-Authors: Conor P Delaney, Jeffrey L. Ponsky, Andrew J. RussAbstract:Laparoscopic Colectomy has become an accepted approach to colon resection. Compared with open Colectomy, the laparoscopic technique is associated with equivalent long-term survival but shorter hospital stays, reduced analgesic requirements, improved cosmesis, and earlier resumption of a normal diet. Notably, right hemiColectomy is an appropriate procedure to perform laparoscopically because it lends itself to a standardized, reproducible technique. In this chapter, we discuss our approach to laparoscopic right Colectomy, clearly outlining each step and the necessary considerations.

Rising post-Colectomy complications in children with ulcerative colitis despite stable Colectomy rates in United States
Journal of Crohn's & colitis, 2014Co-Authors: Ing Shian Soon, Iwona Wrobel, Jennifer Debruyn, Reg Sauve, David L. Sigalet, James Hubbard, Gilaad G. KaplanAbstract:Abstract Background and aims In children with ulcerative colitis, data on temporal Colectomy trends and in-hospital post-Colectomy complications are limited. Thus, we evaluated time trends in Colectomy rates and post-Colectomy complications in children with ulcerative colitis. Methods We identified all children (≤18years) with a diagnosis code of ulcerative colitis (ICD-9: 556.X) and a procedure code of Colectomy (ICD-9: 45.8 and 45.7) in the Kids' Inpatient Database for 1997, 2000, 2003, 2006 and 2009. The incidence of colectomies for pediatric ulcerative colitis was calculated and Poisson regression analysis was performed to evaluate the change in Colectomy rates. In-hospital postoperative complication rates were assessed and predictors for postoperative complications were evaluated using multivariate logistic regression. Results The annual Colectomy rate in pediatric ulcerative colitis was 0.43 per 100,000person-years, which was stable throughout the study period ( P >.05). Postoperative complications were experienced in 25%, with gastrointestinal (13%) and infectious (9.3%) being the most common. Postoperative complication rates increased significantly by an annual rate of 1.1% from 1997 to 2009 ( P =.01). However, other independent predictors of postoperative complications were not identified. Patients with postoperative complications had significantly longer median length of stay (14.3days vs 8.2days; P P Conclusion Colectomy rates across the United States in children with ulcerative colitis have remained stable between 1997 and 2009; however, in-hospital postoperative complication rates have increased.

Postoperative complications following Colectomy for ulcerative colitis in children.
Journal of pediatric gastroenterology and nutrition, 2012Co-Authors: Ing Shian Soon, Iwona Wrobel, Jennifer Debruyn, Reg Sauve, David L. Sigalet, Belle S. Kaplan, Marie-claude Proulx, Gilaad G. KaplanAbstract:BACKGROUND AND AIMS Colectomy rates for ulcerative colitis (UC) and data on postColectomy complications in children are limited. Thus, we assessed Colectomy rates, early postColectomy complications, and clinical predictors in children with UC undergoing a Colectomy. METHODS Children (18 years old or older) with UC who underwent Colectomy from 1983 to 2009 were identified (n=30). All of the medical charts were reviewed. The diagnostic accuracy of International Classification of Diseases codes for UC and Colectomy were validated. The primary outcome was postoperative complications defined as Clavien-Dindo classification grade II or higher. The yearly incidence of colectomies for pediatric UC was calculated and temporal trends were evaluated. RESULTS The sensitivity and positive predictive value of UC and Colectomy International Classification of Diseases codes were 96% and 100%, respectively. The median ages at UC diagnosis and Colectomy were 10.9 and 12.1 years, respectively. All of the children had pancolitis and 63% underwent emergent Colectomy. Postoperatively, 33% experienced at least 1 complication. Patients with emergent Colectomy were more likely to have a postoperative complication compared with patients with elective Colectomy (90% vs 50%; P=0.03). For emergent Colectomy, postoperative complications were associated with a disease flare of ≥2 weeks before admission (60% vs 0%; P=0.03) and >2 weeks from admission to Colectomy (78% vs 22%; P=0.04). The average annual rate of pediatric Colectomy was 0.059/100,000 person-years and stable from 1983 to 2009 (P>0.05). CONCLUSIONS Colectomy UC was uncommon and rates have remained stable. PostColectomy complications were common, especially in patients undergoing emergent Colectomy. Optimizing timing of Colectomy may reduce postoperative complications.

single incision laparoscopic Colectomy for cancer assessment of oncologic resection and short term outcomes in a case matched comparison with standard laparoscopy
Surgery, 2011Co-Authors: Harry T Papaconstantinou, Scott J ThomasAbstract:Purpose To compare single-incision laparoscopic (SIL) with multiport laparoscopic (LAP) Colectomy in patients with colon cancer to assess oncologic resection and 1-year outcomes. Methods We compared patients who underwent SIL Colectomy for colon cancer with an equal number of case-matched LAP Colectomy patients based on age, gender, body mass index (BMI), American Society of Anesthesiologists (ASA) score, previous abdominal operations, and operation type. Results of oncologic resection included lymph node (LN) yield and margins. One-year outcomes included cancer recurrence and death. Results Twenty-six patients were identified for SIL and LAP Colectomy groups with no differences in case matching (age, P = .70; gender, P > .99; BMI, P = .74; ASA score, P > .99; previous abdominal operation, P > .99; and operation-type, P > .99). Oncologic resection was similar for both groups. Mean LN yield was 17 (P = .88). There were no positive margins and 2 (8%) patients had proximal/distal margin of Conclusion These data suggest that SIL Colectomy for cancer provides equivalent oncologic resection and 1-year outcomes compared with a standard LAP technique. Further studies are required to determine long-term oncologic outcomes, including recurrence and survival rates.

single incision laparoscopic right Colectomy a case matched comparison with standard laparoscopic and hand assisted laparoscopic techniques
Journal of The American College of Surgeons, 2011Co-Authors: Harry T Papaconstantinou, Nicole E Sharp, Scott J ThomasAbstract:Background Single-incision laparoscopic (SIL) Colectomy is an advance in minimally invasive colorectal surgical techniques. Feasibility and safety of SIL Colectomy has been reported; however, benefits and outcomes are not well-defined. The purpose of this study was to compare outcomes of SIL right Colectomy with multiport laparoscopic (LAP) and hand-assisted laparoscopic (HAL) techniques. Methods SIL right Colectomy cases performed between August 2009 and April 2010 were case-matched for age, sex, body mass index, American Society of Anesthesiologists score, previous abdominal surgery, and pathology to an equivalent number of LAP and HAL right Colectomy cases. Data analyzed included operative time, procedure conversion, incision length, length of hospital stay, 30-day hospital readmission, surgical site infection and maximum postoperative pain score. Results Twenty-nine patients were analyzed in each of 3 groups (SIL, LAP, and HAL). The mean age (p = 0.96), body mass index (p = 0.48), American Society of Anesthesiologists score (p = 0.74), and rate of previous abdominal operation (p = 0.95) were similar, and sex and pathology were identical among groups. Operative time and conversion rates were similar. The incision length for SIL (4.5 cm) and LAP (5.1 cm) groups was similar, and both were significantly shorter than HAL group (7.2 cm; p Conclusions SIL right Colectomy can improve patient recovery through a decrease in early postoperative pain and shorter length of hospital stay when compared with established laparoscopic techniques.
