Oncological Feasibility of Laparoscopic Distal Pancreatectomy for Adenocarcinoma: A Single-Institution Comparative Study (original) (raw)

Laparoscopic distal pancreatectomy for pancreatic cancer is safe and effective

Surgical Endoscopy and Other Interventional Techniques, 2017

Purpose To compare the short-term and oncologic outcomes of patients with pancreatic ductal adenocarcinoma (PDAC) undergoing laparoscopic distal pancreatectomy (LDP) and open distal pancreatectomy (ODP). Methods Consecutive cases of distal pancreatectomy (DP) (n = 422) were reviewed at a single high-volume institution over a 10-year period (2005-2014). Inclusion criteria consisted of any patient with PDAC by surgical pathology. Ninety-day outcomes were monitored through a prospectively maintained pancreatic resection database. The Social Security Death Index was used for 5-year survival. Twoway statistical analyses were used to compare categories; variance was reported with standard error of the mean; * indicates P value \0.05. Results Seventy-nine patients underwent DP for PDAC. Thirty-three underwent LDP and 46 ODP. There were no statistical differences in demographics, BMI, and ASA classification. Intraoperative and surgical pathology variables were comparable for LDP versus ODP: operative time (3.9 ± 0.2 vs. 4.2 ± 0.2 h), duct size, gland texture, stump closure, tumor size (3.3 ± 0.3 vs. 4.0 ± 0.4 cm), lymph node harvest (14.5 ± 1.1 vs. 17.5 ± 1.2), tumor stage (see table), and negative surgical margins (77 vs. 87%). Patients who underwent LDP experienced lower blood loss (310 ± 68 vs. 597 ± 95 ml; P = 0.016*) and required fewer transfusions (0 vs. 13; P = 0.0008*). Patients who underwent LDP had fewer positive lymph nodes (0.8 ± 0.2 vs. 1.6 ± 0.3; P = 0.04*) and a lower incidence of type C pancreatic fistula (0 vs. 13%; P = 0.03*). Median follow-up for all patients was 11.4 months. Long-term oncologic outcomes revealed similar outcomes including distant or local recurrence (30 vs. 52%; P = 0.05) and median survival (18 vs. 15 months), as well as 1-year (73 vs. 59%), 3-year (22 vs. 21%), and 5-year (20 vs. 15%) survival for LDP and ODP, respectively. Conclusions The results of this series suggest that LDP is a safe surgical approach that is comparable from an oncologic standpoint to ODP for the management of pancreatic adenocarcinoma.

A Multicenter Analysis of Distal Pancreatectomy for Adenocarcinoma: Is Laparoscopic Resection Appropriate?

Journal of the American College of Surgeons, 2010

As compared with open distal pancreatectomy (ODP), laparoscopic distal pancreatectomy (LDP) affords improved perioperative outcomes. The role of LDP for patients with pancreatic ductal adenocarcinoma (PDAC) is not defined. STUDY DESIGN: Records from patients undergoing distal pancreatectomy (DP) for PDAC from 2000 to 2008 from 9 academic medical centers were reviewed. Short-term (node harvest and margin status) and longterm (survival) cancer outcomes were assessed. A 3:1 matched analysis was performed for ODP and LDP cases using age, American Society of Anesthesiologists (ASA) class, and tumor size.

Extended laparoscopic distal pancreatectomy for adenocarcinoma in the body and tail of the pancreas: a single-center experience

Langenbeck's Archives of Surgery, 2018

Purpose Extended resection is required for pancreatic adenocarcinoma infiltrating adjacent organs and structures. The role of laparoscopy in this setting is unclear. In this study, the outcomes of extended laparoscopic distal pancreatectomy (ELDP) for pancreatic body/tail adenocarcinoma were examined. Methods Perioperative and oncologic data were analyzed in patients undergoing laparoscopic distal pancreatectomy (LDP) for adenocarcinoma at Oslo University Hospital. ELDP was defined as suggested by the International Study Group for Pancreatic Surgery. The outcomes of ELDP were compared to those following standard LDP (SLDP). Results From August 2001 to June 2016, 460 consecutive patients underwent LDP for pancreatic neoplasms including 116 (25%) adenocarcinoma. SLDP and ELDP were applied in 78 and 31 patients, respectively. The adrenal gland (33%) and colon (21%) were the most frequently resected organs during ELDP. The latter was associated with larger tumor size (5.5 vs 4 cm, p = 0.03), longer operative time (236 vs 158 min, p = 0.001) and higher conversion rate (16 vs 3%, p = 0.019) compared with SLDP. Morbidity and 90-day mortality were similar. Median follow-up was 18 months. In patients with ductal adenocarcinoma, ELDP (n = 22) was associated with significantly shorter recurrence-free and overall survival than SLDP (n = 59) (6.2 vs 9.6 months, p = 0.047 and 12.9 vs 27 months, p < 0.01, respectively). Conclusion Although technically challenging, ELDP is feasible in patients with adenocarcinoma providing acceptable surgical outcomes. ELDP for ductal adenocarcinoma is associated with worse prognosis than SLDP, while its potential benefits over palliative care deserve further scrutiny.

Laparoscopic distal pancreatectomy for pancreatic ductal adenocarcinoma: Long-term oncologic outcomes after standard resection

Surgery, 2017

Background. Surgical resection is the only curative option in patients with pancreatic ductal adenocarcinoma. Little is known about the oncologic outcomes of laparoscopic distal pancreatectomy. This bi-institutional study aimed to examine the long-term oncologic results of standard laparoscopic distal pancreatectomy in a large cohort of patients with pancreatic ductal adenocarcinoma. Methods. From January 2002 to March 2016, 207 patients underwent standard laparoscopic distal pancreatectomy for with pancreatic ductal adenocarcinoma at Oslo University Hospital-Rikshospitalet (Oslo, Norway) and Asan Medical Centre (Seoul, Republic of Korea). After the exclusion criteria were applied (distant metastases at operation, conversion to an open operation, loss to follow-up), 186 patients were eligible for the analysis. Perioperative and oncologic variables were analyzed for association with recurrence and survival. Results. Median overall and recurrence-free survivals were 32 and 16 months, while 5-year overall and recurrence-free survival rates were estimated to be 38.2% and 35.9%, respectively. Ninety-six (52%) patients developed recurrence: 56 (30%) extrapancreatic, 27 (15%) locoregional, and 13 (7%) combined locoregional and extrapancreatic. Thirty-seven (19.9%) patients had early recurrence (within 6 months of operation). In the multivariable analysis, tumor size >3 cm and no adjuvant chemotherapy were associated with early recurrence (P = .017 and P = .015, respectively). The Cox regression model showed that tumor size >3 cm and lymphovascular invasion were independent predictors of decreased recurrence-free and overall survival. Conclusion. Standard laparoscopic distal pancreatectomy is associated with satisfactory long-term oncologic outcomes in patients with pancreatic ductal adenocarcinoma. Several risk factors, such as tumor size >3 cm, no adjuvant chemotherapy, and lymphovascular invasion, are linked to poor prognosis after standard laparoscopic distal pancreatectomy.

Definition of a standard lymphadenectomy in surgery for pancreatic ductal adenocarcinoma: a consensus statement by the International Study Group on Pancreatic Surgery (ISGPS)

Surgery, 2014

The lymph node (Ln) status of patients with resectable pancreatic ductal adenocarcinoma is an important predictor of survival. The survival benefit of extended lymphadenectomy during pancreatectomy is, however, disputed, and there is no true definition of the optimal extent of the lymphadenectomy. The aim of this study was to formulate a definition for standard lymphadenectomy during pancreatectomy. During a consensus meeting of the International Study Group on Pancreatic Surgery, pancreatic surgeons formulated a consensus statement based on available literature and their experience. The nomenclature of the Japanese Pancreas Society was accepted by all participants. Extended lymphadenectomy during pancreatoduodenectomy with resection of Ln's along the left side of the superior mesenteric artery (SMA) and around the celiac trunk, splenic artery, or left gastric artery showed no survival benefit compared with a standard lymphadenectomy. No level I evidence was available on prognos...

Survival after resection for ductal adenocarcinoma of the pancreas

British Journal of Surgery, 1996

A retrospective study was performed of 113 patients who underwent surgical resection of carcinoma of the pancreas from 1970 to 1992. The postoperative mortality rate was 15 per cent (5 per cent in the last 11 years). The actuarial S-year survival rate was 12 per cent. Survival was significantly influenced by age (P:0'03), vascular resection (P:0'02), radicality of operation (P:0'01), number of transfused blood units (P:0'01), tumour differentiation (P:0'002), lymph node status (P:0'001), perineural invasion (P:0'01), tumour size (P:0'008), preoperative diabetes (P:0'001) and stage (P:0'0001).

Distal Pancreatectomy for Resectable Adenocarcinoma of the Body and Tail of the Pancreas

Journal of Gastrointestinal Surgery, 2005

The study goal was to analyze outcome after distal pancreatectomy for three subtypes of adenocarcinoma to determine the role of en bloc resection in surgical management. A secondary aim was to identify those clinicopathologic factors correlating with survival in an analysis limited to ductal adenocarcinoma. Medical records of consecutive patients undergoing distal pancreatectomy for adenocarcinoma between 1987 and 2003 were reviewed. A comparative analysis was undertaken of the safety and outcome of patients undergoing standard and en bloc resections. Clinicopathologic factors for patients undergoing distal pancreatectomy for ductal adenocarcinoma were subjected to both univariate and multivariate survival analyses. Ninety-three patients underwent resection for ductal adenocarcinoma (66, 71%), mucinous cystadenocarcinoma (18, 19%), or adenocarcinoma associated with intraductal papillary mucinous neoplasm (IPMN) (9, 10%). En bloc resection was required in 33 (35%) patients. There was no operative mortality. Median survival was 15.5 months, 30.2 months, and 50.7 months for ductal adenocarcinoma, mucinous cystadenocarcinoma, and adenocarcinoma associated with IPMN, respectively. Patients undergoing en bloc resection had a higher overall complication rate, required more transfusions and more intensive care unit admissions, and had a higher rate of positive margins; however, there were no deaths. For ductal adenocarcinoma, tumor size greater than 3.5 cm, age greater than 60 years, and stage were factors that correlated with survival on a univariate analysis. None were significant on multivariate analysis. Four patients with ductal adenocarcinoma were actual 5-year survivors. While en bloc resections are associated with a higher rate of complications, the majority are self-limited and mortality is low. Resection, including adjacent organs, should be performed when appropriate. Long-term survival for patients with cystadenocarcinoma or IPMN-associated adenocarcinoma can be anticipated. While rare, long-term survival for patients with ductal adenocarcinoma after distal pancreatectomy can be achieved.
