Preoperative drainage in pancreatic cancer.

Van der Gaag et al. conclude that preoperative biliary drainage in patients undergoing surgery for cancer of the head of the pancreas increases complications. Previous studies have shown that stenting is associated with a doubling in the risk of wound infection and an overall slightly increased risk of any complication

Edoardo Bassini (1844-1924): father of modern-day hernia surgery.

According to Roman scripture, it was Celsus who attempted the first inguinal hernia repair in history during the first century A.D. His attempts were unsuccessful and resulted in an early recurrence of the hernia, which eventually led to the patient’s death.1 Over the next two millennia, little understanding was gained regarding the anatomy of the inguinal canal. It was only in the last 100 years that major advancements in herniorrhaphy were established, thanks in large part to the work of Edoardo Bassini, who revolutionized the surgical treatment of the inguinal hernia with a technique which has become the basis of modern-day herniorrhaphy

Christian Albert Theodor Billroth, M.D., founding father of abdominal surgery (1829-1894).

In the 1800s, the field of surgery was in its infancy, somewhat primitive and embryonic. The technical nature of surgery was the basis for the dividing line between the disciplines of surgery and internal medicine. Sterilization was not a common practice. Radical surgical resections and experimentation in medicine were shunned. With his boldness equaled only by his innovation and resourcefulness, Theodor Billroth would become a pioneer not only in the development of modern surgery, but also in the advancement of its cultural and historical significance

Samuel D. Gross, M.D. (1805-1884): an innovator, even in death.

Dr. Samuel Gross\u27 contributions to the field of surgery are well known and range from numerous clinical advances to pioneering scholarship and professional activities. Dr. Gross was ceaselessly ambitious and even remarked in his autobiography that his ‘‘conviction has always been that is far better for a man to wear out than to rust out.’’1 It is through this frame of motivation that Dr. Gross lived his life

Does Intraoperative Radiation Therapy Improve Local Tumor Control in Patients Undergoing Pancreaticoduodenectomy for Pancreatic Adenocarcinoma? A Propensity Score Analysis

Background: Locoregional recurrence (LRR) is an important factor after pancreaticoduodenectomy (PD) for pancreatic cancer. IORT administered to the resection bed may improve local tumor control. Methods: We performed a retrospective analysis of patients who underwent PD at Thomas Jefferson University Hospital (TJUH) between 1995 and 2005 to identify patients who underwent resection with and without intraoperative radiation therapy (IORT). Data collected included age, gender, complications, margin status, stage, survival, and recurrence. Unadjusted analyses of the IORT and non-IORT groups were performed using Fisher’s chi-square method for discrete variables and Wilcoxon Rank Sum test for continuous variables. To account for biases in patient selection for IORT, a propensity score was calculated for each patient and adjusted statistical analyses were performed for survival and recurrence outcomes. Results: Between January 1995 and November 2005, 122 patients underwent PD for perimpullary tumors, including 99 pancreatic cancers. Of this group, 37 patients were treated with IORT, and there was adequate follow-up information for a group of 46 patients who underwent PD without IORT. The IORT group contained a higher percentage of Stage IIB or higher tumors (65%) than in the non-IORT group (39.1%), though differences in stage did not reach significance (p = 0.16). There was a non-significant decrease in the rate of LRR in patients who had IORT (39% non-IORT vs. 23% IORT, p = 0.19). The median survival time of patients who received IORT was 19.2 months, which was not significantly different than patients managed without IORT, 21.0 months (p=0.78). In the propensity analyses, IORT did not significantly influence survival or recurrence after PD. Conclusions: IORT can be safely added to management approaches for resectable pancreatic cancer, with acceptable morbidity and mortality. IORT did not improve loco-regional control and did not alter survival for patients with resected pancreatic cancer. IORT is an optional component of adjuvant chemoradiation for pancreatic cancer. In the future, IORT may be combined with novel therapeutic agents in the setting of a clinical trial in order to attempt to improve outcomes for patients with pancreatic cancer.

Initiation of a critical pathway for pancreaticoduodenectomy at an academic institution -- the first step in multi-disciplinary team building

Objective: This study was designed to identify quantifiable parameters to track performance improvements brought about by the implementation of a critical pathway for complex alimentary tract surgery. Background: Pancreaticoduodenectomy (PD) is a complex general surgical procedure performed in varying numbers at many academic institutions. Originally associated with significant perioperative morbidity and mortality, multiple studies have now shown that this operation can be performed quite safely at high volume institutions that develop a particular expertise. Critical pathways are one of the key tools used to achieve consistently excellent outcomes as these institutions. It remains to be determined if implementation of a critical pathway at an academic institution with prior moderate experience with PD will result in performance gains and improved outcomes. Methods: Between January 1, 2004 and October 15, 2006 135 patients underwent PD, 44 before the implementation of a critical pathway on October 15, 2005, and 91 after. Perioperative and postoperative parameters were analyzed retrospectively to identify those that could be used to track performance improvement and outcomes. Key aspects of the pathway include spending the night of surgery in the intensive care unit with careful attention to fluid balance, early mobilization on post-operative day one, aggressive early removal of encumbrances such as nasogastric tubes and urinary catheters, early post-operative feeding, and targeting discharge for postoperative day 6 or 7. Results: The pre- and post-pathway implementation groups were not statistically different with regards to age, sex, race, or pathology (malignant versus benign). Perioperative mortality, operative blood loss, and number of transfused units of packed red blood cells were also similar. As compared to the pre-pathway group, the post-pathway group had a significantly shorter postoperative length of stay (13 versus 7 days, P ≤ 0.0001), operative time (435 ± 14 minutes versus 379 ± 12 minutes, P ≤ 0.0001), and in room non-operative time (95 ± 4 minutes versus 76 ± 2 minutes, P ≤ 0.0001). Total hospital charges were significantly reduced from $240,242 ±$32,490 versus $126,566 ±$4883 (P ≤ 0.0001) after pathway implementation. Postoperative complication rates remained constant (44% pre-pathway versus 37% after, P = NS). Readmission rates were not negatively affected by the reduction in length of stay, with a 7% readmission rate prior to implementation and a 7.7% rate after implementation. Conclusion: Implementation of a critical pathway for a complex procedure can be demonstrated to improve short-term outcomes at an academic institution. This improvement can be quantified and tracked and has implications for better utilization of resources (greater OR and hospital bed availability) and overall cost containment. With a very conservative estimate of 75 pancreaticoduodenectomies per year by this group, this translates to a savings of 450 hospital days and over $8,550,000 in hospital charges on an annual basis. As we enter the pay for performance era, institutions will be required to generate such data in order to retain patient volumes, attract new patients, and receive incentive payments for high quality services rendered

Surgical Apgar Score (SAS) Predicts Perioperative Morbidity and Length of Stay in Patients Undergoing Esophagectomy at a High-Volume Center

Background: Esophagectomy is a procedure that carries considerable morbidity. Many studies have evaluated factors to predict patients at risk and improve clinical outcomes. The aim of this study was to determine whether the SAS predicts complications, length of stay, and anastomotic leak for patients undergoing esophagectomy at a high-volume institution.https://jdc.jefferson.edu/surgeryposters/1002/thumbnail.jp

Optimal technical management of stump closure following distal pancreatectomy: a retrospective review of 215 cases.

BACKGROUND: Pancreatic fistula (PF) is a major source of morbidity following distal pancreatectomy (DP). Our aim was to identify risk factors related to PF following DP and to determine the impact of technique of transection and stump closure. METHODS: We performed a retrospective review of 215 consecutive patients who underwent DP. Perioperative and postoperative data were collected and analyzed with attention to PF as defined by the International Study Group of Pancreatic Fistula. RESULTS: PF developed in 36 patients (16.7%); fistulas were classified as Grade A (44.4%), B (44.4%), or C (11.1%). The pancreas was transected with stapler (n = 139), cautery (n = 70), and scalpel (n = 3). PF developed in 19.8% of remnants which were stapled/oversewn and 27.7% that were stapled alone (p = 0.4). Of the 69 pancreatic remnants transected with cautery and oversewn, a fistula developed in 4.3% (p = 0.004 compared to stapled/oversewn; p = 0.006 compared to stapled/not sewn). The median length of postoperative hospital stay was significantly increased in patients who developed PF (10 vs. 6 days, p = 0.002) CONCLUSION: The method of transection and management of the pancreatic remnant plays a critical role in the formation of PF following DP. This series suggests that transection using electrocautery followed by oversewing of the pancreatic remnant has the lowest risk of PF

Impact of Obesity on Perioperative Morbidity and Mortality Following Pancreaticoduodenectomy

Background: Obesity has been implicated as a risk factor for perioperative and postoperative complications. The aim of this study was determine the impact of obesity on morbidity and mortality in patients undergoing pancreaticoduodenectomy (PD). Study Design: Between January 2000 and July 2007, 262 patients underwent PD at Thomas Jefferson University Hospital (TJUH), of whom 240 had complete data, including body mass index (BMI) for analysis. Data on BMI, preoperative parameters, operative details, and post-operative course were collected. Patients were categorized as obese (BMI \u3e30 kg/m2), overweight (25≤BMI\u3c30), or normal weight (BMI\u3c25). Complications were graded according to previous published scales. Other endpoints included length of postoperative hospital stay, blood loss, and operative duration. Analyses were performed using univariate and multivariable models. Results: There were 103 (42.9%) normal weight, 71 (29.6%) overweight and 66 (27.5%) obese patients. There were 5 perioperative deaths (2.1%) with no differences across BMI categories. A significant difference in median operative duration and blood loss between obese and normal weight patients was identified (439vs. 362.5minutes, p= 0.0004; 650 vs. 500 ml, p=0.0139). Furthermore, median length of stay was marginally significantly longer for by BMI (9.5 vs. 8 days, p=0.095). While there were no significant differences in superficial wound infections, obese patients did have an increased rate of serious complications compared to normal weight patients (24.2% vs. 13.6%, respectively; p=0.10). Conclusions: Obese patients undergoing PD have a significantly increased blood loss and longer operative time, but do not have a significantly increased length of postoperative hospital stay or rate of serious complications. These findings should be considered when assessing patients for operation and when counseling patients regarding operative risk, but do not preclude obese individuals from undergoing definitive pancreatic surgery
