Prospective study of outcomes after percutaneous biliary drainage for malignant biliary obstruction.

BACKGROUND: Percutaneous biliary drainage (PBD) is used to relieve malignant bile duct obstruction (MBO) when endoscopic drainage is not feasible. Little is known about the effects of PBD on the quality of life (QoL) in patients with MBO. The aim of this study was to evaluate changes in QoL and pruritus after PBD and to explore the variables that impact these changes. MATERIALS AND METHODS: Eligible patients reported their QoL and pruritus before and after PBD using the Functional Assessment of Cancer Therapy-Hepatobiliary instrument (FACT-HS) and the Visual Analog Scale for Pruritus (VASP). Instruments were completed preprocedure and at 1 and 4 weeks following PBD. RESULTS: A total of 109 (60 male/49 female) patients enrolled; 102 (94%) had unresectable disease. PBD was technically successful (hepatic ducts cannulated at the conclusion of procedure) in all patients. There were 2 procedure-related deaths. All-cause mortality was 10% (N = 11) at 4 weeks and 28% (N = 31) at 8 weeks post-PBD with a median survival of 4.74 months. The mean FACT-HS scores declined significantly (P < .01) over time (101.3, 94.8, 94.7 at baseline, 1 week, 4 weeks, respectively). The VASP scores showed significant improvement at 1 week with continued improvement at 4 weeks (P < .01). CONCLUSIONS: PBD improves pruritus but not QoL in patients with MBO and advanced malignancy. There is high early mortality in this population.

What is the yield of intraoperative ultrasonography during partial hepatectomy for malignant disease?

BACKGROUND: Previous studies have shown that intraoperative ultrasonography (IOUS) during hepatic resection for malignancy changes the operative plan or identifies occult unresectable disease in a large proportion of patients. This study was undertaken to reassess the yield of IOUS in light of recent improvements in preoperative staging. STUDY DESIGN: Patients with potentially resectable primary or metastatic hepatic malignancies subjected to exploration, bimanual palpation of the liver, and IOUS were evaluated prospectively. Intraoperative findings were recorded, and preoperative imaging studies were reanalyzed by radiologists blinded to the intraoperative findings. The extent of disease based on preoperative imaging was compared with the intraoperative findings. RESULTS: From October 1997 until November 1998, 111 patients were evaluated. At exploration, a total of 77 new findings or findings different than suggested on the imaging studies were identified in 61 patients (55%), the most common of which was additional hepatic tumors (n = 37). Thirty-five of 77 (45%) new findings were identified by IOUS alone and 10 (13%) by palpation alone; the remainder were identified by both palpation and IOUS. Forty-seven of 61 patients (77%) underwent a complete resection despite new intraoperative findings, with a modification (n = 28) or no change (n = 19) in the planned operation. Twenty-one patients (19%) had new findings identified only on IOUS. Thirteen of these patients underwent resection with no change in the operative plan, six underwent a modified resection and two were considered to have unresectable disease based solely on the findings of IOUS. CONCLUSIONS: In patients with hepatic malignancies submitted to a potentially curative resection, new intraoperative findings or findings different than suggested on preoperative imaging studies are common. But resection with no change in the operative plan or a modified resection is still possible in the majority of patients despite such findings. The findings on IOUS alone rarely lead to a change in the operative plan.

Drainage is unnecessary after elective liver resection.

PURPOSE: A prospective, randomized trial was performed to determine if intra-abdominal drainage catheters are necessary after elective liver resection. PATIENTS AND METHODS: Between April 1992 and April 1994, 120 patients subjected to liver resection, stratified by extent of resection and by surgeon, were randomized to receive or not receive operative closed-suction drainage. Operative blood loss was not an exclusion criteria, and no patient who consented to the study was excluded. RESULTS: Eighty-seven patients (73%) had resection of one hepatic lobe or more (27 lobectomies, 54 trisegmentectomies, and 6 bilobar atypical resections) and 33 had less than a lobectomy (8 wedge resections or enucleations, 9 segmentectomies, and 16 bisegmentectomies). Eighty-four patients (70%) had metastatic cancer and 36 patients (30%) had primary liver pathology. There were no differences in outcome, including length of hospital stay (no drain, 13.4 +/- 0.9 days; drain, 13.1 +/- 0.8 days; P = not significant [NS]), mortality (no drain, 3.3%; drain, 3.3%), complication rate (no drain, 43%; drain, 48%; P = NS), or requirement for subsequent percutaneous drainage (no drain, 18%; drain, 8%; P = NS). All infected collections (n = 3) occurred in operatively drained patients. Two other complications were directly related to the operatively placed drains. One patient developed a subcutaneous abscess at the drain site, and a second developed a subcutaneous drain tract tumor recurrence as the only current site of recurrence. CONCLUSION: In the first 50 consecutive resections performed since the conclusion of this trial, only 4 patients (8%) have required subsequent percutaneous drainage. We conclude that abdominal drainage is unnecessary after elective liver resection.

Ocular tear film bubble counts after recreational compressed air diving.

Other authors have demonstrated an increase in tear film bubble counts following dry, compressed air dives. We examined the lower tear film meniscus for the presence of bubbles in 42 divers after compressed air dives on a single day and in 11 divers undergoing repetitive, multi-day diving exposures over 5 days. After diving, bubble counts increased significantly (P < 0.01) from predive values. From a predive median (inter-quartile range) of 0 (0-0.33) bubbles/eye, single-day divers reached a maximum bubble count at 48 h after diving of 1 (0-2.25) bubbles/eye. Similarly, from a predive count of 0.33 (0-1) bubbles/eye, multi-day divers had increased bubble counts from 24 h following their first dive until 24 h following their final dive when counts were 1.67 (0.92-3.08) bubbles/eye. Bubble counts were not significantly correlated with inert gas load, body mass index, age, or diving experience. We confirm that tear film bubble counts are raised after wet compressed air diving as previously described following dry diving.

Gallbladder carcinoma discovered during laparoscopic cholecystectomy: aggressive reresection is beneficial.

BACKGROUND: This study attempted to determine whether aggressive surgical therapy is warranted after gallbladder carcinoma is discovered during or after laparoscopic cholecystectomy. METHODS: The clinical course and outcome of 42 consecutive patients with laparoscopically discovered gallbladder carcinoma seen over a 5-year period at a tertiary referral center were examined. Nine of the patients had TNM classified T2 tumors and 32 had full thickness penetration of the gallbladder including 16 T3 and 16 T4 tumors. RESULTS: At reexploration, 22 of the patients were found to have lymph node, peritoneal, or bilateral liver disease precluding reresection. Nineteen patients underwent liver resection (13 trisegmentectomies and 6 bisegmentectomies), portal lymphadenectomy, and hepaticojejunostomy as the definitive surgical procedure for the carcinoma. There was 1 perioperative death, and the median hospital stay was 11 days (range, 6-28 days). At last follow-up 17 of the 22 nonresected patients had died, with a median survival of 5 months. With a follow-up of 16 months, only 3 of the resected patients had died. CONCLUSIONS: The authors conclude that aggressive resection of gallbladder carcinoma discovered laparoscopically is safe and effective.

Liver resection in the elderly.

BACKGROUND: The operative mortality rate for hepatic resection in the elderly has been reported to be as high as 40 per cent for extended resection. METHODS: An increasing need to justify use of limited healthcare resources prompted a prospective assessment of 133 consecutive hepatic resections performed in 30 months in patients over 65 years of age. RESULTS: The overall mortality rate was 4 per cent. Mean(s.e.m.) hospital stay was 13(1) days, and admission to the intensive care unit was required for only eight patients. By univariate analysis, male sex (P = 0.003), preoperative jaundice (P = 0.01), abnormal preoperative electrocardiogram (P = 0.05) and poor American Society of Anesthesiologists (ASA) physical status classification (P = 0.01) were predictors of cardiopulmonary complications. In a multivariate analysis only male sex and ASA classification predicted complications (P = 0.05). The 1-, 2- and 3-year survival rates for the entire group were 78, 66 and 50 per cent respectively. All survivors returned to good functional status (mean(s.e.m.) peak postoperative Karnofsky score 95(1)). When outcome was compared with that in 244 patients younger than 65 years of age who had liver resection during the same interval, the only difference was a longer mean hospital stay for the older patients: mean(s.d.) 13.4(0.5) versus 11.9(0.4) days for those aged less than 65 years (P = 0.02). CONCLUSION: Major hepatic resection can be performed in patients over 65 years old with acceptable morbidity and mortality rates.

Palliation of irresectable hilar cholangiocarcinoma with biliary drainage and radiotherapy.

Twelve patients with irresectable or recurrent hilar cholangiocarcinoma were treated with internal biliary drainage followed by intraluminal (iridium-192) and external-beam radiotherapy. Biliary drainage was accomplished by means of a combined surgical and interventional radiological approach. Initial biliary decompression was performed surgically by tumour resection, intrahepatic biliary enteric bypass or distal biliary-enteric anastomosis with a temporary stent. Maintenance of internal biliary drainage and application of intraluminal radiotherapy were accomplished radiologically with the use of percutaneous dilatation and metallic expandable biliary endoprostheses. Median survival was 14.5 months; all 12 patients survived for at least 6 months. Early complications during radiotherapy were minor and included two patients with cholangitis and one with transient haemobilia. Jaundice was relieved in ten of 12 patients, while episodes of cholangitis were seen during long-term follow-up in 11 (median 1.5 episodes per patient). Internal biliary drainage, in conjunction with radiotherapy, appears to be safe and effective palliation of irresectable or recurrent hilar cholangiocarcinoma. Patients can maintain a reasonable quality of life with an acceptable incidence of cholangitis, without the hindrance of external drainage devices.
