Clinical and operative outcomes of patients with acute cholecystitis who are treated initially with image-guided cholecystostomy.

ABSTRACT: Percutaneous cholecystostomy (PC) tube placement followed by delayed cholecystectomy has been shown to be an effective treatment option in high-risk populations such as older and critically ill patients. The goal of this study was to review the short- and long-term clinical and operative outcomes of patients with acute cholecystitis initially treated with PC tube placement.We conducted a retrospective review of patients who underwent image-guided PC tube insertion between 2001 and 2011 at the Royal University Hospital or St. Paul's Hospital, Saskatoon. Clinical outcomes, complications and elective cholecystectomy follow-up were noted.A total of 140 patients underwent PC tube insertion, 76 men and 64 women with a mean age of 68.4 (standard deviation 17.7) years. Of the 140, 94 (67.1%) had an American Society of Anesthesiologists classification score of III or IV. Percutaneous cholecystostomy tubes remained in place for a median of 21.0 days, and the median hospital stay was 7.0 days. Readmission owing to complications from PC tubes occurred in 21 patients (15.0%), and 10 (7.1%) were readmitted with recurrent cholecystitis after tube removal. Forty-four patients (31.4%) returned for subsequent elective cholecystectomy, of whom 32 (73%) underwent laparoscopic cholecystectomy, 4 (9%) underwent open cholecystectomy, and 8 (18%) underwent laparoscopic converted to open cholecystectomy.Percutaneous cholecystostomy is a safe procedure that can be performed in patients who are older or have numerous comorbidities. However, less than one-third of such patients in our cohort subsequently had the definitive intervention of elective cholecystectomy, with a high rate of conversion from laparoscopic to open cholecystectomy.

Project description:ObjectiveTo report acute hematological toxicity (HT) in patients receiving post-operative bowel sparing intensity-modulated radiotherapy (IMRT) and cisplatin and its dosimetric predictors.MethodsClinical database of Phase III trial (NCT01279135), that randomized patients to post-operative conformal or intensity modulated radiation therapy, was searched to select patient strata that received bowel sparing IMRT (50 Gy/25#/5 wks) and concurrent cisplatin (40 mg m-2). Pelvic bone marrow (BM) was retrospectively delineated in two sets: whole bone (WB), and freehand (FH) inner cavity of bone. Dose volume histograms (DVH) of BM were obtained. Receiver operating characteristic (ROC) curve identified DVH thresholds that predicted for Grade≥ II HT with highest specificity. Univariate and multivariate analysis was performed.ResultsOverall 75 patients received concurrent cisplatin. Grades I-V HT was observed in 38.7%, 42.7%, 14.7%, 0%, and 0% patients, respectively. Grade ≥ II leukopenia, neutropenia, anemia, and thrombocytopenia were observed in 26%, 40%, 26.5%, and 1.4% respectively. None of the HT resulted in treatment break. On univariate analysis, whole pelvis+ lumbar FH V30 >55% & V40>35%, whole pelvis WB and FH V40 > 35%, and lower pelvis WB and FH V40 >20% correlated for Grade ≥ II leucopenia and neutropenia. None of the BM dose volume constraints predicted for overall HT or neutropenia on multivariate analysis.ConclusionThe IMRT arm of NCT01279135 (PARCER study) that employed strict bowel constraints had unintentional but desirable BM sparing. None of the BM subvolume DVH parameters could be validated on multivariate analysis.Advances in knowledgeThe prospective study reports feasibility of bone marrow sparing with bowel sparing post-operative pelvic IMRT and concurrent chemotherapy for cervical cancer. The present study reports low incidence of hematological and gastrointestinal toxicity during post-operative chemoradiation with IMRT. As both whole bone and freehand pelvis BM contours predicted for HT, hence an easier method of whole bone contouring should continue to be used till further validation of more specific BM subvolumes becomes available. The study results highlight the need for further research into dose volume constraints during post-operative IMRT.
