Background. Laparoscopic cholecystectomy is considered to be gold standard for symptomatic gall stones. As a routine every specimen is sent for histopathological examination postoperatively. Incidentally finding gall bladder cancers in those specimens is around 0.5–1.1%. The aim of this study is to identify those preoperative and intraoperative factors in patients with incidental gall bladder cancer to reduce unnecessary work load on pathologist and cost of investigation particularly in a developing world. Methods. Retrospective records were analyzed from January 2005 to February 2015 in a surgical unit. Demographic data, preoperative imaging, peroperative findings, macroscopic appearance, and histopathological findings were noted. Gall bladder wall was considered to be thickened if ≥3 mm on preoperative imaging or surgeons comment (on operative findings) and histopathology report. AJCC TNM system was used to stage gall bladder cancer. Results. 973 patients underwent cholecystectomy for symptomatic gallstone disease. Gallbladder carcinoma was incidentally found in 11 cases. Macroscopic abnormalities of the gallbladder were found in all those 11 patients. In patients with a macroscopically normal gallbladder, there were no cases of gallbladder carcinoma. Conclusion. Preoperative and operative findings play a pivotal role in determining incidental chances of gall bladder malignancy.
Background and Objectives. Preoperative counseling is effective to foster early postoperative mobilization that reduces pulmonary complications following abdominal surgery. This study aims at evaluating the effect of preoperative counseling regarding postoperative mobilization and its impact on reducing pulmonary complications. Design and Setting. Randomized control trial was conducted at the Department of Surgery of a tertiary care hospital, Karachi. Patients and Materials. Patients who underwent abdominal surgery and met inclusion criteria were recruited. All participants were randomly divided into two groups. Both groups received information about the surgery and Group I received additional counseling for postoperative mobilization. All patients were encouraged for postoperative mobilization. Scholes et al. criteria were used to evaluate postoperative pulmonary complications. Results. In total 232 participants were recruited and divided into two groups. There was no significant difference in participants' age (P = 0.79), duration of surgery (P = 0.5), and pain score (P = 0.1) of both groups. However, significant difference was identified in mobilization from bed to chair and mobilization for >10 minutes. Patients in Group I experienced less pulmonary complications in comparison with Group II.
Background. There has been argument between clinical practitioners about clamping catheter or not prior to its removal after transurethral resection of prostate (TURP). We conducted a clinical trial to assess whether clamping has any role in early bladder tone recovery particularly in patients who undergo TURP. Methods. Randomized clinical trial was conducted at a tertiary care hospital, Karachi from January 2014 to July 2015. Eighty-six study participants who underwent TURP were randomly allocated into two groups of 43 participants each. In Group I, patient's Foley catheter was not clamped prior to its removal and in Group II Foley catheter was clamped. Data of all subjects were analyzed using SPSS version 20. Results. There was no significant difference in age and weight of resected tissues between two groups. Among 4 patients in Group I who required recatheterization, 1 patient was discharged with catheter as compared to Group II in which 2 patients were discharged with catheter (P = 0.99). Only 1 patient (2.3%) in Group II had bleeding which required recatheterization. Length of stay was significantly affected by early and free removal of Foley catheter (P < 0.001). Conclusion. The results of current study identified that clamping whether done or not had no significant impact on urinary retention.
Background: In metastatic urothelial cancer (mUC), bone metastasis (BM) are associated with significant morbidity and mortality, yet their role as an independent prognostic variable remains unclear. We aimed to determine the impact of BM on overall survival (OS) in patients with mUC treated with first-line platinum-based chemotherapy (PBC). Methods: mUC patients receiving PBC at the Princess Margaret Cancer Center, Tom Baker Cancer Center, or Cross Cancer Institute from January 2005 to January 2018 were identified retrospectively using central pharmacy database records. Patient disease, treatment, and response characteristics were collected. Progression-free survival (PFS) and OS were estimated using the Kaplan–Meier method. Variables reaching significance ( p < 0.05) in univariable analysis (UVA) of survival (OS) were included in multivariable analysis (MVA) (Cox). Results: Overall, 376 patients with a median follow-up of 16.8 (range: 2.2–218.3) months were included. Median age was 67 (range: 28–91) years, 76% were male, 63% had an Eastern Cooperative Oncology Group performance status (ECOG PS) of 0–1, and 41% had BM. All patients received first-line PBC. Patients with BM had inferior median PFS (4.9 months (95% CI 3.6–6.2) versus 6.5 months (95% CI 5.4–7.6), p = 0.03) and median OS (8.8 months (95% CI 7.8–9.7) versus 10.8 months (95% CI 9.1–12.5), p = 0.002). In UVA, ECOG PS 2–3 ( p < 0.001), presence of BM ( p = 0.002), and WBC count ⩾ 11,000 cells/mm3 ( p = 0.001) were associated with inferior survival. Prior cystectomy ( p < 0.001) and lack of progression (stable disease, partial or complete response) on treatment was associated with improved OS ( p < 0.001). These variables maintained significance in MVA. Conclusion: In this retrospective study, mUC patients with BM had worse OS suggesting that BM may be an independent negative prognostic factor and including BM as a stratification factor in future mUC clinical trial designs may be warranted. A greater focus must be placed on novel therapeutic strategies to better manage BM to reduce both morbidity and mortality.
415 Background: Metastatic urothelial carcinoma (mUC) is an aggressive disease with a median overall survival (OS) of ≈ 15 months. In the first-line setting, key prognostic factors include ECOG performance status, white blood cell count, and response to treatment per the Galsky nomogram. Bone metastases (BM) in mUC are associated with morbidity and mortality but are grouped with visceral disease; hence, their impact on prognosis is not well established. We aimed to assess the survival impact of BM in mUC patients treated with first-line platinum-based chemotherapy (PBC). Methods: A retrospective collection of patient and tumor characteristics, with clinical response to treatment (complete response [CR], partial response [PR]; stable disease [SD] or progressive disease [PD]) for patients treated at Princess Margaret Cancer Centre, Tom Baker Cancer Centre, and Cross Cancer Institute from 2005-2018 was performed. Progression-free survival (PFS) and OS were estimated using the Kaplan-Meier method. Univariate (UVA) followed by multivariate analysis (MVA) of patient variables [Cox] using PFS and OS was performed. Results: Overall 376 mUC patients were included; 222 (59%) had soft-tissue metastases (STM) only, 70 (19%) had bone-only metastases, and 84 (22%) had both STM and BM. Overall, 35% had PR or CR, 19% had SD, and 39% had PD (7%: unknown response). The median PFS and OS for the whole cohort were 5.6 months (95%CI: 4.8-6.4) and 9.7 months (95% CI: 8.8-10.8) respectively. Select UVA by metastatic site showed inferior PFS for bone-only (p=0.03) and combination STM and BM (p=0.017). Only combination STM and BM were significant on UVA for OS (p=0.002). MVA showed that bone-only metastases (p=0.03) and ECOG 3-4 (p<0.0001) were associated with worse PFS (Table). Predictors of worse OS were the combination of STM and BM (p=0.02), ECOG 3-4 (p=0.001), and WBCs ≥ULN (p=0.02), (Table). Conclusions: BM are a significant predictor of worse outcomes for mUC patients treated with first-line PBC. Consideration as a treatment stratification factor for future studies is suggested. Strategies for the treatment of mUC patients with BM (ie: bone targeted agents) in the first-line setting should be addressed in future trials. [Table: see text]
Background: Despite post-ERCP pancreatitis (PEP) being a major focus of outcomes research in endoscopic retrograde cholangiopancreatography (ERCP), little is known regarding the frequency with which asymptomatic biochemical and/or radiologic pancreatic alterations occur in patients following ERCP. Methods: Adult inpatients undergoing ERCP were identified from a prospective ERCP registry. Patients with any abdominal pain, confirmed PEP, or pancreatitis or abnormal pancreatic enzymes preceding ERCP were excluded. Primary outcomes were asymptomatic lipase elevation on bloodwork within 24 h of ERCP or asymptomatic cross-sectional imaging findings consistent with acute pancreatitis in the absence of clinical PEP within 14 days. Multinomial logistic regression and multiple logistic regression were used to examine associations between exposures and lipase levels and between PEP or imaging findings, respectively. Results: In total, 646 and 187 patients were analyzed as part of the biochemical and radiologic cohorts, respectively. A total of 26.0% of patients had asymptomatic elevations in lipase above the upper limit of normal (ULN) within 24 h, and 9.4% had elevations >3× ULN. A total of 20.9% of patients had incidental findings of enlargement, inflammation/edema/fat stranding, peri-pancreatic fluid collections, and/or necrosis on cross-sectional imaging within 14 days. Pancreatic contrast injection was associated with higher odds of asymptomatic lipasemia (adjusted odds ratio, AOR, 7.22; 95% confidence intervals, CI, 1.13 to 46.02), as was the use of the double-wire technique (AOR 15.74; 95% 1.15 to 214.74) and placement of a common bile duct stent (AOR 4.19; 95% CI 1.37 to 12.77). Over 10 cannulation attempts were associated with the presence of one or more radiologic finding(s) (AOR 33.95; 95% CI 1.64, to 704.13). Conclusions: Significant rates of incidental biochemical and/or radiologic pancreatic abnormalities are present following ERCP. Clinicians should be aware of our findings to minimize misclassification and better direct healthcare utilization.
