Hand-Assisted Laparoscopic Hartmann\’s Reversal is an efficacious and efficient procedure: A case control study
Background: laparoscopy may lower the mortality and morbidity rates of Hartmann’s procedure reversal. However, it remains difficult mainly due to adhesions of the small bowel and the rectal stump.Methods: Retrospective review of the charts of 44 patients who had laparoscopic hand-assisted Hartmann’s reversal (Group A) between 2000 and 2007. On a case-control basis, these patients… Continue Reading

Laparoscopic vs open abdominoperineal resection for rectal cancer
Introduction: This study aimed to compare clinical and oncologic outcomes to laparoscopic (LAPR) and open abdominoperineal resection (OAPR) for rectal cancer.Methods: All consecutive patients undergoing LAPR for primary rectal cancer between 2000 and July 2007 were included. Consecutive cases of OAPR underewent between 1995 and 2007 were compared with LAPR.Results: Twenty four patients with LAPR… Continue Reading

Laparoscopic Colectomy for Severe Ulcerative Colitis in Pregnancy
Introduction: Although uncommon, fulminant ulcerative colitis (UC) during pregnancy has been well described in the surgical literature. Laparoscopic approaches for many surgical emergencies during pregnancy have been shown to be equivalent to open procedures, with all the benefits of minimally invasive surgery. We present the first two reported cases of laparoscopic colectomy as a treatment… Continue Reading

Laparoscopic surgery for transverse colon cancer:transverse colectomy vs. right or left extended colectomy
Background: Several multi-institutional prospective randomized trials have demonstrated not only short-term benefits but also long-term oncological safety using laparoscopy for colon cancer. However, in all prior trials, the transverse colon was excluded. Therefore, it has not been determined whether laparoscopy can be used in the setting of transverse colon cancer. Moreover transverse colectomy for transverse… Continue Reading

Hand assisted laparoscopic surgery for severe ulcerative colitis in a semi-emergency setting
Background: Although minimally invasive approaches have been aggressively employed for ulcerative colitis (UC) in an elective setting, its use in a semi-emergency setting has been only sporadically reported. The objective of this study was to determine the current role of hand-assisted laparoscopic surgery (HALS) for severe UC in a semi-emergency setting.Methods: A retrospective study was… Continue Reading

Minimally invasive colon resection is associated with increased sVEGFR1 and decreased sVEGFR2 plasma levels early after surgery; the net impact is decreased binding of free VEGF which may account for increased plasma VEGF levels early post surgery
Introduction: Plasma VEGF levels are increased after minimally invasive colorectal resection (MICR) for both benign and malignant disease. VEGF, which is critical to both wound healing and tumor growth, induces angiogenesis by binding to endothelial cell bound VEGF-Receptor 1 (VEGFR1) and VEGF-Receptor 2 (VEGFR2). Soluble VEGF-Receptor-1 (sVEGFR1) and soluble VEGF-Receptor-2 (sVEGFR2), which are not capable… Continue Reading

Laparoscopic Restorative Proctocolectomy
Introduction: Although many studies have demonstrated good results with laparoscopic proctocolectomy in patients with ulcerative colitis (UC), most surgical procedure require al least one additional incision bigger than 5 cm to complete the surgery. The aim of this video is to show a laparoscopic proctocolectomy with ileoanal J pouch with complete intracorporeal dissection using 4… Continue Reading

Hand-Assisted Laparoscopic Colectomy for Colon Cancer: Early Clinical and Oncologic Outcomes Comparison with Case-Matched Open Colectomies.
Purpose: To evaluate short term clinical and oncologic outcomes of hand-assisted laparoscopic (HAL) colectomy for cancer compared with case matched open colectomies.Methods: All 168 HAL colorectal procedures performed at out institution between August 2002 and August 2006 were review. Rectal procedures and colectomies performed for benign disease were excluded. Thirty-seven colon cancers remained for analysis.… Continue Reading

Nucleotide-guided Mesorectal Excision (ngme) During Transanal Endoscopic Microsurgery (tem) for Rectal Cancer: Preliminary Study
Introduction: TEM is used for local excision of T1N0 rectal cancer and it has been proposed to treat selected T2-T3 N0 cases after neoadjuvant radiochemotherapy. Standard TEM usually removes few mesorectal lymphnodes immediately adjacent to the tumor, which may leave the histopathological N parameter undefined. This may be a criticism to the use of TEM… Continue Reading

Laparoscopic Assisted Surgery for Rectal Cancer. Our Experience and Results in 430 Cases.
Introduction: Laparoscopic assisted surgery for rectal cancer is still a challenge for surgeons. Actually colorectal surgeons believe that total mesorectal excision provides favorable oncologic results for the treatment of rectal cancer and more and more believe that laparoscopic approach is a good and safe approach to do it. The present study is a feasibility study… Continue Reading

Minimally invasive colorectal resection is associated with a temporary decrease in FGF-2 levels in both cancer and benign indication patients.
Introduction: Fibroblast growth factor-2 (FGF-2) is a promoter of endothelial cell growth and angiogenesis and, thus, plays a role in both wound healing and tumor growth. Elevated blood levels have been reported in cancer (CRC) patients prior to colorectal resection (CR) and some investigators have noted decreased levels 1 month postop. Surgery’s early impact on… 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

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
