What is the appropriate level of the regional lymph node dissection, when we perform the laparoscopic surgery for T1 colorectal cancer?
[Background] Laparoscopic colorectal cancer surgery came to be performed widely, but the oncological validity of this surgery has not been well analyzed. Especially for pathological T1 (pT1) colorectal cancer, the level of lymph nodes (LN) dissection is not clear. [Patients and Method] The study group consists of 321 patients who underwent laparoscopic colorectal resection since… Continue Reading

Hand-Assisted Colon Resection: Better than standard laparoscopy?
Background: Hand-assisted laparoscopic colon resection (HALCR) is an approach which may lessen the need for conversion, shorten operative time, and decrease disposable costs while maintaining the benefits of minimally-invasive surgery. The aim of this study was to compare the clinical outcomes of patients who underwent colon or rectal resections for cancer/adenoma, diverticulitis, or inflammatory bowel… Continue Reading

Use of Routine Intraoperative Endoscopy in Elective Laparoscopic Colorectal Surgery – Can It Further Avoid Anastomotic Failure?
Background: Anastomotic leakage, bleeding and local recurrence remain serious complications of laparoscopic colorectal surgery. We aimed to study the usefulness of routine intraoperative endoscopy (RIOE) in elective laparoscopic colorectal surgery with distal anastomosis to predict postoperative anastomotic failure. Method: A retrospective review of 244 consecutive patients between January 2004 and May 2007 was performed. While… Continue Reading

Does Incision Length Have Any Impact on Short Term Benefits of Laparoscopic Colon Surgery?
INTRODUCTION: With the recent introduction of hand-assist devices in laparoscopic colorectal surgery, there is renewed interest in the impact of incision length. The aim of this study is to define the impact of incision length on short-term postoperative outcomes.METHODS: Consecutive patients undergoing laparoscopic left-sided colorectal resection by 4 surgeons from 4 different academic centers from… Continue Reading

Risk Factors for Postoperative Bleeding After Laparoscopic Appendectomy – Staple Size Matters
It is estimated that approximately 250,000 cases of appendicitis occur annually in the United States, with a lifetime risk of over 8% in males and 6% in females. Since the first description of laparoscopic appendectomy by Semm in 1983, multiple studies have validated its use in the treatment of acute appendicitis. The most common complication… Continue Reading

Gangliocytic Paraganglioma of the Appendix
Introduction: This is a case report of a 61 y/o male with a gangliocytic paraganglioma with focal carcinoid features of the appendix. A literature search was done and this appears to be the second reported case of gangliocytic paraganglioma of the appendix in the modern literature. A previous similar case report in 1999 was described… Continue Reading

A Comparison Study of Laparoscopic , Hand-Assisted Laparoscopic, and Open Techniques for Treatment of Complicated Diverticulitis
INTRODUCTION-Our study was aimed at demonstrating that two laparoscopic methods, complete laparoscopy (LAP) and hand-assisted laparoscopy (HAL) are acceptable techniques for sigmoid resection in patients with complicated diverticulitis as compared to open surgery (OS). METHODS AND PROCEDURES- A retrospective review of 88 patients with complicated diverticulitis diagnosed between February 2003 and August 2007, were divided… Continue Reading

Factors Associated with Colostomy Reversal
Introduction: The natural history of colostomies and end ileostomies for colonic disease is not well documented in the literature. The primary objective of this study is to identify factors which impact colostomy and ileostomy reversal among patients with colonic diseases Methods: A retrospective review of patients with end ileostomies and colostomies was performed at a… Continue Reading

Minimally invasive colorectal resection for malignant disease is associated with an early decrease in TGF Beta plasma levels one day postop and then an increase in levels in the second week after surgery
Introduction: TGF Beta regulates cell growth and proliferation. Although pro-apoptotic in general, in some cancers it promotes tumor angiogenesis via inactivation of the TGF signaling pathway. Some cancers express TGF Beta and it has been reported that elevated blood levels pre-resection are associated with advanced stage disease. Surgery’s impact on TGF Beta levels is unknown.… Continue Reading

Minimally invasive colorectal resection for cancer but not benign disease is associated with a short lived decrease in soluble Tie-2 Receptor levels which likely promotes VEGF-mediated angiogenesis
Introduction: Plasma VEGF levels are increased after minimally invasive colorectal resection (MICR) and likely stimulate angiogenesis in the wound and in residual tumor deposits. Angiopoetin (Ang) 1, via binding to endothelial cell (EC) bound Tie-2 receptor (Tie2) inhibits VEGF mediated angiogenesis while Ang 2 encourages VEGF-related angiogenesis by preventing Ang-1’s effects via competitive binding of… Continue Reading

Totally Laparoscopic Proctocolectomy with Intracorporeal Ileal Pouch -Anal Anastomosis Followed By ‘natural Orifice Specimen Extraction’ (n.o.s.e)
Introduction:Totally laparoscopic proctocolectomy with intracorporeal pouch-anal anastomosis has been rarely reported. In this video, we present a totally laparoscopic proctocolectomy with pouch-anal anastomosis and a novel method of specimen extraction. Methods: We retrospectively studied 7 female patients from 2004-2007. A totally laparoscopic proctocolectomy with ileal pouch-anal anastomosis was successfully performed for all cases. The operating… Continue Reading

Laparoscopic IPAA surgery reduces abdominal and pelvic adhesions
Objectives: Adhesions after open abdominal operations cause >75% of cases of small bowel obstruction. We evaluated adhesions to the anterior abdominal wall and adnexae after laparoscopic ileal pouch anal anastamosis (IPAA).Methods: Patients who underwent laparoscopic proctocolectomy, IPAA and diverting loop ileostomy for Ulcerative Colitis had laparoscopic evaluation of adhesions at closure of ileostomy to assess… Continue Reading

Laparoscopic Sigmoidectomy (ls). Inmediate Outcome in Relation to Primary Disease.
LS is feasible and reproducible and it means the best example of MIS for colon disease. However technical difficulty as well outcome would depend on the initial diagnosis. The aim of this paper has been to asses the outcome differences in relation to the diverse indications for LS. Material and methods. We retrieved from a… Continue Reading

Evaluation of learning curve relating to short-term oncologic parameters for laparoscopic surgery in patients with recto-sigmoid carcinoma
INTRODUCTION: Previous studies analyzing the learning curves in laparoscopic colorectal surgery have focused mainly on non-oncologic outcomes or consisted predominantly of patients with colon cancer. The aim of this study was to analyze the learning curve with particular reference to short-term oncologic outcomes for the laparoscopic approach to recto-sigmoid carcinoma (RSC). MATERIALS AND METHODS: A… Continue Reading

Laparoscopic Surgery for advanced rectal cancer
Background: The laparoscopic approach is accepted as an alternative to open surgery for colon cancer. However, it has not been determined whether laparoscopy can be used in the setting of rectal cancer. Moreover laparoscopic surgery for advanced rectal cancer demands technical experience and needs longer learning time. This study evaluated the peri-operative clinical outcomes and… Continue Reading
