Spiritual issues of family members in a pancreatic cancer chat room.

PURPOSE/OBJECTIVES: To describe spiritual issues addressed by users of a pancreatic cancer informational Web site. DESIGN: Qualitative, descriptive. SETTING: The patient and family chat room of Johns Hopkins Hospital's pancreatic cancer Web site. SAMPLE: 600 postings on the pancreatic cancer Web site. METHODS: Identification of categories and themes in Web postings using the constant comparison method of content analysis. MAIN RESEARCH VARIABLES: Spirituality, relationship of the person posting a message (poster) to the person with cancer. FINDINGS: Relationship of the poster to the person with pancreatic cancer was explicit in 68% (n = 410) of the 600 postings, and 83% of those 410 postings indicated that the poster was a family member. Issues of spirituality appeared in 19% (n = 114) of the 600 postings and addressed four themes: spiritual convergence, reframing suffering, hope, and acceptance of the power of God and eternal life. Six percent of postings were by family members reporting on the death of their loved ones, suggesting that the site also served a bereavement function. CONCLUSIONS: Family members of patients with pancreatic cancer sought and received spiritual comfort in a variety of forms in an Internet-based cancer chat room. IMPLICATIONS FOR NURSING: Nurse developers of cancer information Web sites should periodically assess how the sites are being used and apply the information to the refinement of the sites to better meet user needs. Further study is needed to develop and evaluate cancer Web sites as an evolving medium for providing spiritual support to family members of patients with life-threatening forms of cancer.

Does pancreatic duct stenting decrease the rate of pancreatic fistula following pancreaticoduodenectomy? Results of a prospective randomized trial.

Pancreatic duct stenting remains an attractive strategy to reduce the incidence of pancreatic fistulas following pancreaticoduodenectomy (PD) with encouraging results in both retrospective and prospective studies. We performed a prospective randomized trial to test the hypothesis that internal pancreatic duct stenting reduces the development of pancreatic fistulas following PD. Two hundred thirty-eight patients were randomized to either receive a pancreatic stent (S) or no stent (NS), and stratified according to the texture of the pancreatic remnant (soft/normal versus hard). Four patients were excluded from the study; in three instances due to a pancreatic duct that was too small to cannulate and in the other instance because a total pancreatectomy was performed. Patients who randomized to the S group had a 6-cm-long segment of a plastic pediatric feeding tube used to stent the pancreaticojejunostomy anastomosis. In patients with a soft pancreas, 57 randomized to the S group and 56 randomized to the NS group. In patients with a hard pancreas, 58 randomized to the S group and 63 randomized to the NS group. The S and NS groups for the entire study population, as well as for the subgroup of high-risk patients with soft pancreata, were similar as regard to demographics, past medical history, preoperative symptoms, preoperative procedures, and intraoperative data. The pancreatic fistula rate for the entire study population was 9.4%. The fistula rates in the S and NS subgroups with hard pancreata were similar, at 1.7% and 4.8% (P = 0.4), respectively. The fistula rates in the S and NS subgroups with soft pancreata were also similar, at 21.1% and 10.7% (P = 0.1), respectively. A nonstatistically significant increase in the pancreatic fistula rate in the S group persisted after adjusting for the operating surgeon and technical details of the operation (e.g., anastomotic technique, anastomotic orientation, pancreatic duct size, and number of intra-abdominal drains placed). In patients with soft pancreata, 63% percent of the pancreatic fistulas in stented patients required adjustment to the clinical pathway (including two deaths), compared to 47% of the pancreatic fistulas in patients in the NS group (P = 0.3). Internal pancreatic duct stenting does not decrease the frequency or the severity of postoperative pancreatic fistulas.

One thousand consecutive pancreaticoduodenectomies.

OBJECTIVE: To trace the evolution of pancreaticoduodenectomy from the decade of the 1960s through the first decade of the new Millenium, through the experience of one surgeon doing 1000 consecutive operations. SUMMARY BACKGROUND DATA: A regional resection of the head of the pancreas was first performed successfully by Kausch in 1909. The operation was popularized by Whipple in 1935, who reported 3 pancreaticoduodenectomies. Because of a hospital mortality of approximately 25%, the operation was performed infrequently until the 1980s. From the 1980s on, experience with this complex alimentary tract operation increased, and high-volume centers developed. This resulted in a significant drop in hospital mortality and allowed institutions and individuals to gain large experiences. METHODS: Between March 1969 and May 2003, 1000 consecutive pancreaticoduodenectomies were performed by a single surgeon. A retrospective review of a prospectively maintained database was performed to determine the management and outcome of these patients, as well as to document the evolution of this operative procedure over 5 decades. RESULTS: The median operative time decreased significantly over the decades, being 8.8 hours in the 1970s and 5.5 hours during the 2000s. Postoperative length of stay dropped from a median of 17 days in the 1980s to 9 days in the 2000s. There were only 10 postoperative/hospital deaths, for a mortality of 1%. A total of 405 patients underwent pancreaticoduodenectomy for adenocarcinoma of the head of the pancreas. Overall 5-year survival was 18%; for the lymph node-negative patients, it was 32%; and for node-negative, margin-negative patients, it was 41%. CONCLUSIONS: Pancreaticoduodenectomy has become a commonly performed operation in many tertiary care centers. Operative time, blood loss, and length of stay have dropped substantially. The operation has become safe, with a low hospital mortality. It has become an effective operation for pancreatic cancer in those patients in whom their tumor is margin negative and node negative.

Pancreaticoduodenectomy with or without distal gastrectomy and extended retroperitoneal lymphadenectomy for periampullary adenocarcinoma--part 3: update on 5-year survival.

The study objective was to update the survival analysis at the 5-year mark of patients undergoing standard versus radical (extended) pancreaticoduodenectomy (PD) for periampullary adenocarcinoma (cancers of the pancreas, ampulla, common bile duct, and duodenum). A prospective randomized trial was performed (April 1996 through June 2001) comparing survival after pylorus-preserving PD resection (standard) to survival after PD with distal gastrectomy and retroperitoneal lymphadenectomy (radical). An interim report (Ann Surg 1999;229:613) and report after closing the trial (Ann Surg 2002;236:355) showed no differences in survival between the standard and radical groups. Two hundred ninety-nine patients were randomized to either the standard or radical group. Five patients were excluded from final analysis because final pathology failed to reveal adenocarcinoma. The 5-year survival of the two groups was evaluated. The median live patient follow-up is now 64 months (5.33 years). For all periampullary cancer patients, those undergoing standard resection had 1- and 5-year survival rates of 78% and 25%, respectively, compared with 76% and 31% (P = 0.57) for those patients in the radical group. For pancreatic adenocarcinoma patients, the 1- and 5-year survival rates in the standard group were 75% and 13%, respectively, compared with 73% and 29% in the radical group (P = 0.13). The increased morbidity rate, longer operative time, and similar survival for radical PD led us to conclude that pylorus-preserving PD without retroperitoneal lymphadenectomy should be the procedure of choice for most patients with resectable periampullary adenocarcinoma. While there is an intriguing trend toward improved survival in patients with pancreatic adenocarcinoma in the radical group, this trend may be largely accounted for by the higher incidence of microscopically margin positive resections in the standard resection group (21%) compared with a 5% incidence in the radical group (P = 0.002).

Surgical management of bile duct injuries sustained during laparoscopic cholecystectomy: perioperative results in 200 patients.

OBJECTIVE: A single institution retrospective analysis of 200 patients with major bile duct injuries was completed. Three patients died without surgery due to uncontrolled sepsis. One hundred seventy-five patients underwent surgical repair, with a 1.7% postoperative mortality and a complication rate of 42.9%. SUMMARY BACKGROUND DATA: The widespread application of laparoscopic cholecystectomy (LC) has led to a rise in the incidence of major bile duct injuries (BDI). Despite the frequency of these injuries and their complex management, the published literature contains few substantial reports regarding the perioperative management of BDI. METHODS: From January 1990 to April 2003, a prospective database of all patients with a BDI following LC was maintained. Patients' charts were retrospectively reviewed to analyze perioperative surgical management. RESULTS: Over 13 years, 200 patients were treated for a major BDI following LC. Patient demographics were notable for 150 women (75%) with a mean age of 45.5 years (median 44 years). One hundred eighty-eight sustained their BDI at an outside hospital. The mean interval from the time of BDI to referral was 29.1 weeks (median 3 weeks). One hundred nine patients (58%) were referred within 1 month of their injury for acute complications including bile leak, biloma, or jaundice. Twenty-five patients did not undergo a surgical repair at our institution. Three patients (1.5%) died after delayed referral before an attempt at repair due to uncontrolled sepsis. Twenty-two patients, having intact biliary-enteric continuity, underwent successful balloon dilatation of an anastomotic stricture. A total of 175 patients underwent definitive biliary reconstruction, including 172 hepaticojejunostomies (98%) and 3 end-to-end repairs. There were 3 deaths in the postoperative period (1.7%). Seventy-five patients (42.9%) sustained at least 1 postoperative complication. The most common complications were wound infection (8%), cholangitis (5.7%), and intraabdominal abscess/biloma (2.9%). Minor biliary stent complications occurred in 5.7% of patients. Early postoperative cholangiography revealed an anastomotic leak in 4.6% of patients and extravasation at the liver dome-stent exit site in 10.3% of patients. Postoperative interventions included percutaneous abscess drainage in 9 patients (5.1%) and new percutaneous transhepatic cholangiography and stent placement in 4 patients (2.3%). No patient required reoperation in the postoperative period. The mean postoperative length of stay was 9.5 days (median 9 days). The timing of operation (early, intermediate, delayed), presenting symptoms, and history of prior repair did not affect the incidence of the most common perioperative complications or length of postoperative hospital stay. CONCLUSIONS: This series represents the largest single institution experience reporting the perioperative management of BDI following LC. Although perioperative complications are frequent, nearly all can be managed nonoperatively. Early referral to a tertiary care center with experienced hepatobiliary surgeons and skilled interventional radiologists would appear to be necessary to assure optimal results.

Standard vs. radical pancreaticoduodenectomy for periampullary adenocarcinoma: a prospective, randomized trial evaluating quality of life in pancreaticoduodenectomy survivors.

This study was designed to assess the health-related quality of life (QOL) of patients who had been randomly assigned to either standard or radical pancreaticoduodenectomy for periampullary adenocarcinoma. Pancreaticoduodenectomy has been performed in increasing numbers for periampullary adenocarcinoma. The appropriate extent of resection (standard vs. radical [extended]) remains controversial, particularly as concerns survival benefit. Past reports comparing standard vs. radical resection have suggested that the more extensive resection is attended by negative functional outcomes (diarrhea and weight loss) and poorer QOL, diminishing the impact of any possible survival advantage of the radical resection. A prospective, randomized single-institution trial comparing standard pancreaticoduodenectomy (pylorus preservation preferred) to radical pancreaticoduodenectomy (including distal gastrectomy and retroperitoneal lymphadenectomy) evaluated 299 patients with periampullary adenocarcinoma between April 1996 and June 2001. A standard Functional Assessment of Cancer Therapy-Hepatobiliary (FACT-Hep) QOL survey designed for hepatobiliary cancer was sent to 150 of these patients surviving pancreaticoduodenectomy. QOL and functional status were assessed via a series of subscale scores for physical, social, emotional, and functional well-being. A total of 105 QOL surveys (70%) were returned and analyzed, with 55 of the patients having been randomized to the standard group and 50 to the radical group. The patients were evaluated at a mean of 2.2 years after pancreaticoduodenectomy. The two groups were statistically similar with regard to multiple parameters including age at operation (64.6 years), race, intraoperative blood transfusions, pathologic diagnosis and staging, and perioperative complications. The radical group had a significantly higher percentage of men (66% vs. 44%; P = 0.02), a longer operative time (369 minutes vs. 327 minutes; P < 0.001), and a longer postoperative length of hospital stay (13.6 days vs. 10.1 days; P < 0.01). The FACT-Hep total QOL scores were similar between the standard and radical groups: 143.5 vs. 147.3, respectively. Additionally, the individual FACT-G subscale scores evaluating physical (22.1 vs. 23.3), social (24.5 vs. 24.4), emotional (19.2 vs. 19.6), and functional well-being (20.6 vs. 22.4) were comparable between the standard and radical groups. Subgroup analyses based on pathologic diagnosis (pancreatic, ampullary, distal bile duct, etc.) failed to reveal any differences in QOL assessment between the standard and radical pancreaticoduodenectomy groups. Finally, QOL measures were similar when comparing time since operation (<2 years' follow-up vs. >2 years' follow-up) and age (< or =65 years vs. >65 years). This is the largest report comparing QOL assessment in survivors of pancreaticoduodenectomy randomized between standard and radical resection. These data demonstrate no differences in long-term QOL between standard and radical resection. These results imply that no negative long-term QOL measures are associated with radical pancreaticoduodenectomy (as performed in this study) for periampullary adenocarcinoma.

Major bile duct injuries associated with laparoscopic cholecystectomy: effect of surgical repair on quality of life.

OBJECTIVE: To assess the quality of life (QOL) of patients after surgical reconstruction of a major bile duct injury from laparoscopic cholecystectomy (LC). SUMMARY BACKGROUND DATA: The incidence of bile duct injuries has increased dramatically since the introduction and widespread use of LC. Previous reports show that at long-term follow-up, most patients surgically repaired will have a successful outcome as measured by standard clinical parameters. However, there is a general impression that these patients have an impaired QOL. Data addressing QOL of these patients are limited. METHODS: A standard QOL questionnaire was sent to 89 patients after successful surgical repair of a major bile duct injury from a LC treated at the Johns Hopkins Hospital between 1990 and 2000. The instrument consisted of 30 items on a visual analog scale categorized into physical (15 items), psychological (10 items), and social (5 items) domains. The same questionnaire was sent to age- and sex-matched healthy controls (n = 100) and to patients who underwent uncomplicated LC (n = 100). An additional portion of the questionnaire inquired about outcome measures and legal action undertaken by patients. RESULTS: Overall QOL scores for bile duct injury patients in the three domains (physical, psychological, and social) were 76%, 77%, and 75%, respectively. QOL scores were comparable to those of patients undergoing uncomplicated LC and healthy controls in the physical and social domains but were significantly different in the psychological domain. Presenting symptoms, prior repair, level of injury, number of stents, length of postoperative stenting, and length of follow-up did not influence QOL scores. Repaired patients reported similar rates of abdominal pain, change in bowel habits, use of pain medications, and recent symptoms of fever or chills as LC controls. Thirty-one percent of responding bile duct injury patients reported having sought legal recourse for their injury. All QOL domain scores were significantly lower in the patients who pursued a lawsuit versus those who did not. CONCLUSIONS: This study provides formal data evaluating QOL after surgical repair of major bile duct injuries from LC. Although there was a significant difference in the QOL as evaluated from a psychological dimension, bile duct injury patients reported QOL scores in the physical and social domains comparable to those of control patients. The decreased QOL assessment in the psychological dimension may be attributable to the prolonged, complicated, and unexpected nature of these injuries. The presence of a lawsuit appears to be associated with a poorer QOL assessment.

Pancreaticoduodenectomy with or without distal gastrectomy and extended retroperitoneal lymphadenectomy for periampullary adenocarcinoma, part 2: randomized controlled trial evaluating survival, morbidity, and mortality.

OBJECTIVE: To evaluate, in a prospective, randomized single-institution trial, the end points of operative morbidity, operative mortality, and survival in patients undergoing standard versus radical (extended) pancreaticoduodenectomy. SUMMARY BACKGROUND DATA: Numerous retrospective reports and a few prospective randomized trials have suggested that the performance of an extended lymphadenectomy in association with a pancreaticoduodenal resection may improve survival for patients with pancreatic and other periampullary adenocarcinomas. METHODS: Between April 1996 and June 2001, 299 patients with periampullary adenocarcinoma were enrolled in a prospective, randomized single-institution trial. After intraoperative verification (by frozen section) of margin-negative resected periampullary adenocarcinoma, patients were randomized to either a standard pancreaticoduodenectomy (removing only the peripancreatic lymph nodes en bloc with the specimen) or a radical (extended) pancreaticoduodenectomy (standard resection plus distal gastrectomy and retroperitoneal lymphadenectomy). All pathology specimens were reviewed, fully categorized, and staged. The postoperative morbidity, mortality, and survival data were analyzed. RESULTS: Of the 299 patients randomized, 5 (1.7%) were subsequently excluded because their final pathology failed to reveal periampullary adenocarcinoma, leaving 294 patients for analysis (146 standard vs. 148 radical). The two groups were statistically similar with regard to age (median 67 years) and gender (54% male). All the patients in the radical group underwent distal gastric resection, while 86% of the patients in the standard group underwent pylorus preservation ( <.0001). The mean operative time in the radical group was 6.4 hours, compared to 5.9 hours in the standard group ( =.002). There were no significant differences between the two groups with respect to intraoperative blood loss, transfusion requirements (median zero units), location of primary tumor (57% pancreatic, 22% ampullary, 17% distal bile duct, 3% duodenal), mean tumor size (2.6 cm), positive lymph node status (74%), or positive margin status on final permanent section (10%). The mean total number of lymph nodes resected was significantly higher in the radical group. Of the 148 patients in the radical group, only 15% (n = 22) had metastatic adenocarcinoma in the resected retroperitoneal lymph nodes, and none had retroperitoneal nodes as the only site of lymph node involvement. One patient in the radical group with negative pancreaticoduodenectomy specimen lymph nodes had a micrometastasis to one perigastric lymph node. There were six perioperative deaths (4%) in the standard group versus three perioperative deaths (2%) in the radical group ( = NS). The overall complication rates were 29% for the standard group versus 43% for the radical group ( =.01), with patients in the radical group having significantly higher rates of early delayed gastric emptying and pancreatic fistula and a significantly longer mean postoperative stay. With a mean patient follow-up of 24 months, there were no significant differences in 1-, 3-, or 5-year and median survival when comparing the standard and radical groups. CONCLUSIONS: Radical (extended) pancreaticoduodenectomy can be performed with similar mortality but some increased morbidity compared to standard pancreaticoduodenectomy. The data to date fail to indicate that a survival benefit is derived from the addition of a distal gastrectomy and retroperitoneal lymphadenectomy to a pylorus-preserving pancreaticoduodenectomy.

Diagnostic laparoscopy for periampullary and pancreatic cancer: what is the true benefit?

The role of diagnostic laparoscopy in patients with periampullary and pancreatic malignancies is controversial. A retrospective review was performed including all patients (n = 188) with a periampullary or pancreatic malignancy who underwent both CT and laparotomy at our institution between January 1997 and December 1999. The overall resectability rate for all periampullary cancers was 67.3% (115 of 171 patients). This compared favorably with the resectability rate for cancers of the pancreatic body and tail (3 of 17 patients, 17.6%; P < 0.01 vs. periampullary cancers). Fifty percent of patients with periampullary cancers were unresectable because of metastatic disease, whereas metastatic disease precluded resection in 64.3% of patients with cancers of the pancreatic body and tail. After patients undergoing operative palliation were eliminated, a nontherapeutic laparotomy would have been precluded by the use of diagnostic laparoscopy in only 2.3% of patients with periampullary cancers (4 of 171 patients). In contrast, 6 (35.3%) of 17 patients with cancers of the pancreatic body and tail underwent a nontherapeutic laparotomy (P < 0.01 vs. periampullary cancers). One hundred fifty-eight (84%) of the 188 CT reports reviewed could be definitively categorized as either "likely to be resectable" or "likely to be unresectable." The remaining 16% were equivocal. Of the 107 patients categorized as likely to be resectable, 89 were actually resected (83.2%). In contrast, only 10 of the 51 patients categorized as likely to be unresectable could be resected (19.6%).

Cholecystectomy, liver resection, and pylorus-preserving pancreaticoduodenectomy for gallbladder cancer: report of five cases.

Carcinoma of the gallbladder is an uncommon yet highly malignant disease with a poor overall prognosis. Surgical resection offers the only hope for cure in patients with this type of cancer, but resection is often impossible because of advanced disease at the time of presentation. Patients with locally advanced gallbladder cancer, however, may occasionally be amenable to management by adding pancreaticoduodenectomy to cholecystectomy and liver resection. A retrospective review of patient records at the Johns Hopkins Hospital identified five patients with gallbladder cancer with peripancreatic lymph node involvement, who were treated by surgical resection including pancreaticoduodenectomy. The preoperative evaluation, operative technique, pathologic findings, and outcome were reviewed for each patient. Follow-up was obtained via clinic visit or telephone contact. All five patients underwent resection of the gallbladder cancer with an operation that included pylorus-preserving pancreaticoduodenectomy to remove the peripancreatic lymph nodes. In addition, four of the five patients underwent a nonanatomic liver resection. There were no in-hospital deaths. Two patients had postoperative complications; one had persistent drainage from a T-tube site and one had an anastomotic leak from the hepaticojejunostomy. Four patients have died of recurrent tumor during follow-up at intervals ranging from 11 months to 23 months. The fifth patient is alive and free of clinical disease at 42 months after operation. Carcinoma of the gallbladder is a highly malignant disease that is often not amenable to surgical cure. There is a select group of patients, however, in whom adding a pylorus-preserving pancreaticoduodenectomy can result in a potentially curative operation by removing extensive regional spread to the peripancreatic lymph nodes.

The effect of a Frequently Asked Questions module on a pancreatic cancer Web site patient/family chat room.

The Internet provides access to health information and a supportive community with similar illness concerns. Securing accurate information about treatment and prognosis is important to those with pancreatic cancer given its high mortality and short survival. The purpose of this descriptive-comparative study was to determine the effect of a Frequently Asked Questions (FAQ) module on postings in the chat room of a pancreatic cancer Web site. Six hundred postings were analyzed. Three themes were isolated: information seeking, giving, or both; support seeking, giving, or both; and reporting status or death. Information included treatments, nutrition, prognosis, end-of-life care, cost of care, symptoms, and support (social, emotional, spiritual, or physical). A greater proportion of postings sought information after the FAQ module was added, although questions about medical treatment decreased, whereas questions about prognosis and end-of-life care nearly doubled. There was no difference in the proportion of postings addressing support. Medical treatment was the most common treatment reported and pain was the most common symptom reported. This study supported the addition of a FAQ module to a pancreatic cancer Web site and revealed the need for information regarding pain management and care giving at the end of life.
