ABSTRACT
Objective To study the cause and management of difficult laparoscopic appendectomy.Method A retrospective analysis of 102 difficult laparoscopic appendectomies was performed. Results The associating factors leading to operative difficulty were as follows:adhesion of peri-appendix in 44 cases,gangrene at root of appendix in 21 cases,special location of appendix in 17 cases,abdominal adhesion in 12 cases,obesity and inflatable intestine in 8 cases. Laparoscopic appendectomy was successfully performed in 96 cases(94.1%,96/102) ,and no intestinal leakage or massive hemorrahge occurred. Conclusions Adhesion of peri-appendix is the most common cause in difficult laparoscopic appendectomy,and gangrene at root of appendix is the most difficult one. Reasonable management for appendix stump contributes to successful operation.
ABSTRACT
Objective To quantify the benefit of primary Pdmor removal in patients with differently presenting incurable coloreetal cancer,while no other therapy combined.Methods One hundred and forty-three consecutive patients were operated for incurable colorectal cancer(91 undergoing resective and 52 non-resective procedures),with the purpose of comparing homogenous populations and of identifying whether the patients got benefit from primary tumor resection.Results In patients with resectable primary tumors,resective procedures were associated with longer median survival than non-resective procedures(10 months vs 3 months),patients with distant spread without neoplastic ascites/implanting metastasis got benefit from primary tumor removal(P＜0.01).The complication of resective procedures was not significantly differ-ent from that of non-resective procedares(P＞0.05).Conclusion Palliative resection of primary colorectal cancer should be pursued in patients with unresectable distant metastasis whenever the primary tumor is technically resectable.
