The surgical treatment of chronic pancreatitis and associated ductal calculi typically involves drainage of the main pancreatic duct or parenchymal resection. Treatment of isolated symptomatic pancreatic duct calculi is usually approached by endoscopic techniques. Herein is described a case report of operative transduodenal extraction of symptomatic pancreatic calculi of the ventral pancreas in a patient with a prior distal pancreatectomy. This case represents an uncommon yet valuable option in selected patients in whom endoscopic treatments have failed or are unavailable. [ABSTRACT FROM AUTHOR]

The application of laparoscopic techniques for abdominal procedures has been achieved with varying success. The general acceptance of laparoscopic splenectomy (LS) may be hindered by its infrequent performance and difficulty in manipulating the spleen. A retrospective review of splenectomies performed for primary splenic pathology was done to assess the role and outcome of LS. One hundred fifty LSs were performed from July 1995 through September 1999. Over that time period the proportion of LS performed increased steadily from 17 to 75 per cent of all splenectomies. The primary indications for splenectomy included immune thrombocytopenic purpura in 75 (50%), lymphoma/leukemia 36 (24%), and splenomegaly 19 (13%). There were 86 females and 64 males. Immediately before operation 36 patients (4%) had a platelet count <50,000/ mL, and 24 patients (16%) a hemoglobin <10 mg per cent. The mean operative time was 161 minutes with an average blood loss of 138 [sup 3](<50-800). The mean morcellated weight of the entire group was 411 g (33-3300) indicating generally large splenic size. In the 37 patients with splenomegaly the mean weight was 735 g (293-3300). There were two conversions to open splenectomy. Two patients with hematologic malignancy, splenomegaly, and cytopenias died from overwhelming post-splenectomy sepsis (1.3%). Morbidity occurred in 14 (9%) with the most common complication being pancreatitis in seven (5%). The median length of postoperative stay was 2.4 days (range 1-5). In summary LS has rapidly replaced the open approach for nearly all elective splenectomies in adults and children. When performed with the patient in the lateral position it can be accomplished with minimal morbidity, even in complex patients, including those with splenomegaly. [ABSTRACT FROM AUTHOR]

Background and Objective: Five-year survival in pancreatic adenocarcinoma is less than 20%. While previous studies have postulated that a carbohydrate antigen 19-9 (CA19-9) threshold could predict outcome of resection, the role for CA19-9 in decision-making remains unclear. This study aims to assess whether CA19-9 levels combined with tumor size improve prediction of post-resection survival. Method: A retrospective analysis was conducted on 109 patients with pancreatic adenocarcinoma who underwent perioperative chemotherapy followed by resection. The primary outcome of mortality was, divided into short (<1 year) or prolonged (>2 years). Univariate and multivariable analyses compared the tumor size-adjusted CA19-9 between the outcome groups. Results: Twenty-seven (24.78%) and eighty-two (75.23%) patients were in the short survival and prolonged-survival groups, respectively. The mean CA19-9 was significantly greater in the short vs prolonged group (P <.001). Analyzing CA19-9 level by tumor size, the association of high CA19-9 and short survival was significant for small (≤2 cm) and large tumor (>4 cm), but not for intermediate-size tumors (2-4 cm). Adjusting for preoperative variable did not change this association. Conclusion: CA 19-9 in combination with tumor size better identifies patients with prolonged post-resection survival. This prediction is most accurate in patients with either small (≤2 cms) or large (>4 cms) tumors compared to intermediate-size tumors. [ABSTRACT FROM AUTHOR]

Background: Gallbladder cancer (GBC) is the most common biliary tract malignancy and has a poor prognosis. The clinical significance of focal vs diffuse GBC remains unclear. Methods: A retrospective review was conducted on all patients with non-metastatic GBC at a quaternary care center. Pathology was reviewed, and gallbladder cancer pattern was defined based on the extent of mucosal involvement; "diffuse" if the tumor was multicentric or "focal" if the tumor was only in a single location. Patients undergoing liver resection and portal lymphadenectomy were considered to have definitive surgery. The primary outcome was overall survival and assessed by Kaplan-Meier curves. Results: 63 patients met study criteria with 32 (50.7%) having diffuse cancer. No difference was observed in utilization of definitive surgery between the groups (14 [43.8%] with focal and 12 [38.7%] with diffuse, P =.88). Lymphovascular invasion (P =.04) and higher nodal stage (P =.04) were more common with diffuse GBC. Median overall survival was significantly improved in those with focal cancer (5.1 vs 1.2 years, P =.02). Although not statistically significant, this difference in overall survival persisted in patients who underwent definitive surgery (4.3 vs 2.4 years, P =.70). Discussion: Patients with diffuse involvement of the gallbladder mucosa likely represent a subset with aggressive biology and worse overall survival compared to focal disease. These findings may aid surgeons in subsequent surgical and medical decision-making for patients with GBC. [ABSTRACT FROM AUTHOR]

Laparoscopic resection has become the standard means for removal of normal-sized spleens in many medical centers. The application of minimally invasive techniques in the setting of splenomegaly is less well defined and was previously considered a contraindication to the laparoscopic approach. The purpose of this prospective study of consecutive patients was to compare the outcomes of patients undergoing laparoscopic splenectomy for normal-sized spleens (150 g or less) versus those with clear evidence of splenomegaly (500 g or greater). One hundred forty-two patients met the inclusion criteria. The most common diagnosis in the normal-sized spleen group was idiopathic thrombocytopenia purpura (67 of 82, 82%). Malignant hematologic diseases (lymphoma and leukemia) were the most common diagnoses in the splenomegaly group (35 of 60, 58%). Mean operative times (127 vs 172 minutes) and estimated blood loss (123 vs 173 cm3) were lower for those patients with normal-sized spleens (P < 0.05). There were no statistical differences in conversion rates, lengths of stay, or complications between the two groups. We conclude that laparoscopic splenectomy is safe and effective in the setting of splenomegaly despite modest but statistically longer operative times and increased operative blood loss when compared with laparoscopic splenectomy for normal-sized spleens.
