Xiao D, Zhu L, Xiong S, Yan X, Jiang Q, Wang A, Jia Y. Outcomes of endoscopic ultrasound-guided ablation and minimally invasive surgery in the treatment of pancreatic insulinoma: a systematic review and meta-analysis. Front Endocrinol (Lausanne) 2024; 15:1367068. [PMID: 38645424 PMCID: PMC11026617 DOI: 10.3389/fendo.2024.1367068] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Accepted: 03/25/2024] [Indexed: 04/23/2024] Open
Abstract
Background and aims Most pancreatic insulinomas can be treated by minimally invasive modalities. The aim of this meta-analysis was to assess the clinical outcomes of endoscopic ultrasound (EUS)-guided ablation and minimally invasive surgery (MIS) in the treatment of pancreatic insulinoma. Materials and methods Online databases were searched for relevant studies. The primary aim was to compare the rates of adverse events (AEs) and the secondary aims were to compare the clinical and technical success rates, length of hospital stays, and symptom recurrence rates between EUS and MIS approaches. Results Eight studies with 150 patients were identified that reported EUS-guided ablation outcomes, forming the EUS group, and 9 studies with 236 patients reported MIS outcomes, forming the MIS group. The pooled median age of the included patients in the EUS group was greater than that of the MIS group (64.06 vs. 44.98 years old, p < 0.001). Also, the technical success rate was significantly higher in the EUS group (100% vs. 96.6%, p = 0.025), while the clinical success was significantly higher (6%) in the MIS group (94% vs. 98.7%, p = 0.021). The AE rates (18.7% vs. 31.1%, p = 0.012) and severe AE rates (1.3% vs. 7.9%, p = 0.011) were significantly lower in the EUS group. The median length of hospital stay in the EUS group (2.68 days, 95% CI: 1.88-3.48, I2 = 60.3%) was significantly shorter than in the MIS group (7.40 days, 95% CI: 6.22-8.58, I2 = 42.2%, p < 0.001). The recurrence rate was significantly higher in the EUS group (15.3% vs. 1.3%, p < 0.001). Conclusions EUS-guided ablation is associated with a lower AE rate and a shorter length of hospital stay, but a higher recurrence rate for the treatment of insulinoma compared with MIS. The EUS approach may be an alternative, even first-line, treatment for poor surgery candidates.

Abstract
Insulinoma is a rare functional neuroendocrine tumor of pancreas. The only recommended treatment is surgical removal. We present a case of a 46-year-old female patient who underwent the enucleation of insulinoma localized nearby pancreatic main duct after preoperative endoscopic insertion of pancreatic stent. The tumor was safely identified during the surgery and was enucleated without injury of pancreatic duct or postoperative complications.

Abstract
BACKGROUND Outcomes of patients with pancreatic neuroendocrine tumors (panNETs) undergoing surgical or nonsurgical management and outcomes of enucleation versus standard resection were compared. METHODS MEDLINE, EMBASE, PubMed, Scopus, and Cochrane were queried (2000 to present). All studies comparing patients undergoing surgical versus nonsurgical treatments, or enucleation versus standard resection, were included. Pooled risk ratios and 95% CI for survival were calculated. RESULTS Eleven studies met criteria with 1491 resected and 1607 nonsurgically managed patients. Meta-analysis showed improved overall survival with resection at 1 year (risk ratio (RR) = 1.281, CI 1.064-1.542, p = 0.009), 3 years (RR = 1.837, CI 1.594-2.117, p < 0.001), and 5 years (RR = 2.103, CI 1.50-2.945, p < 0.001). OS of patients with resected nonfunctioning panNETs was improved at 3 years (RR = 1.847, CI 1.477-2.309, p < 0.001) and 5 years (RR = 1.767, CI 1.068-2.924, p = 0.027). OS was improved when panNETs ≤2 cm were resected at 3 years (RR = 1.695, CI 1.269-2.264, p < 0.001) and 5 years (RR = 2.210, CI 1.749-2.791, p < 0.001). Fifteen articles met criteria for enucleation versus standard resection (n = 1035; 620 were nonfunctioning). Enucleation had shorter operative time (weighted mean difference (WMD) = -95.6 min, 95% CI -131.4 to -59.8, p < 0.01), less operative blood loss (WMD = -172.6 ml, 95% CI -340 to -5.1, p = 0.04), but increased postoperative pancreatic fistula (POPF) (RR = 2.08, 95% CI 1.39-3.12, p < 0.01). CONCLUSION Surgical resection of panNETs, including small and nonfunctioning, appears to be associated with improved OS. Enucleation is associated with shorter operative time, less blood loss, but greater incidence of POPF. Prospective, randomized clinical trials are needed to confirm these results.

Abstract
Insulinoma is the most common functioning islet cell tumor of the pancreas, with an annual incidence of 4 cases/1 million individuals. It is treated by surgical methods. Open surgery was once considered the standard approach for the treatment of insulinoma. However, the procedure is traumatic and requires a large incision, which does not satisfy the growing expectations of minimally invasive management of small-sized tumors. Insulinomas are usually benign solitary tumors and mostly occur sporadically, which makes them suitable candidates for laparoscopic management. The potential advantages of laparoscopic management of insulinoma over open surgery include shorter duration of hospitalization, quicker recovery, and better cosmetic effect. However, because of the small tumor size as well as the depth and uncertainty of the location of the tumor, laparoscopic localization of the lesion without tactile sensation is difficult. Laparoscopic ultrasonography can detect about 90% of insulinomas, and its sensitivity is comparable to that of manual palpation along with intraoperative ultrasonography during open surgery; thus, it ensures the feasibility of laparoscopic management of insulinoma and reinforces its advantage as a minimally invasive procedure. Laparoscopic ultrasonography is vital for the localization of insulinomas and characterization of the surrounding pancreatic structure and should, therefore, be considered an integral part of the laparoscopic management of insulinoma.

Abstract
Insulinomas are rare pancreatic neuroendocrine tumors that are most commonly benign, solitary, and intrapancreatic. Uncontrolled insulin overproduction from the tumor produces neurological and adrenergic symptoms of hypoglycemia. Biochemical diagnosis is confirmed by the presence of Whipple’s triad, along with corroborating measurements of blood glucose, insulin, proinsulin, C-peptide, β-hydroxybutyrate, and negative tests for hypoglycemic agents during a supervised fasting period. This is accompanied by accurate preoperative localization using both invasive and non-invasive imaging modalities. Following this, careful preoperative planning is required, with the ensuing procedure being preferably carried out laparoscopically. An integral part of the laparoscopic approach is the application of laparoscopic intraoperative ultrasound, which is indispensable for accurate intraoperative localization of the lesion in the pancreatic region. The extent of laparoscopic resection is dependent on preoperative and intraoperative findings, but most commonly involves tumor enucleation or distal pancreatectomy. When performed in an experienced surgical unit, laparoscopic resection is associated with minimal mortality and excellent long-term cure rates. Furthermore, this approach confers equivalent safety and efficacy rates to open resection, while improving cosmesis and reducing hospital stay. As such, laparoscopic resection should be considered in all cases of benign insulinoma where adequate surgical expertise is available.

Abstract
BACKGROUND Single-incision laparoscopic surgery (SILS) may represent an improvement over conventional laparoscopic surgery, and has been applied in many surgical procedures. However, for pancreatic surgery, experience is rather limited. METHODS The clinical records of 11 cases in which transumbilical single-incision laparoscopic distal pancreatectomy (TUSI-LDP) was performed at our institution since June 2009 were retrospectively analyzed, and all the literatures concerning TUSI-LDP were retrospectively reviewed. RESULTS All the 11 patients were female. The ages ranged from 20 to 73 years, with an average age of 38.0 years. The average body mass index (BMI) was 22.67 (18.6-26.2). Most TUSI-LDPs were successfully performed, with only one conversion to multi-incision surgery. Splenic preservation was performed in six cases. The mean operation time was 163.18 ± 63.18 minutes (range 95-300), and the mean intraoperative blood loss was 159.09 ± 181.02 ml (range 10-500 ml). The surgical wounds healed well, with good cosmetic wound healing, and the patients were discharged from hospital in a mean of 7.45 ± 1.44 days (range 5-10). Only one patient developed pancreatic leakage, which ceased spontaneously with only a drain for 61 days. The parameters were comparable with those found in the English literature. CONCLUSIONS These recent experiences suggest that SILS in pancreatic surgery is feasible for a select group of patients with relatively small lesions and low BMI, and that, with the gradual accumulation of surgeons' experience with SILS and improvement of laparoscopic instruments, it might become a safe option for some patients.

Abstract
BACKGROUND Laparoscopic spleen-preserving distal pancreatectomy is gaining acceptance for the treatment of insulinomas of the pancreatic body and tail. The aim of this report is to evaluate the feasibility, safety and outcomes of this procedure in a retrospective series. METHODS From May 2004 to November 2013, 9 patients underwent laparoscopic spleen-preserving distal pancreatectomy for benign insulinomas in our department. Tumors were single and sporadic in eight patients, while the remaining patient had insulinomas in the setting of multiple endocrine neoplasia type 1. Tumors were located by preoperative imaging in all cases. Laparoscopic ultrasound was always performed to guide the surgical procedure. RESULTS All the operations were carried out laparoscopically with a mean operative time of 110 min (range 90-210 min) and a mean blood loss of 50 ml (range 30-120 ml). One patient (11.1%) died on the 22nd post-operative day for massive intra-abdominal bleeding associated with pancreatitis of the stump. Two patients (22.2%) developed pancreatic fistula that healed conservatively. Mean postoperative hospital stay was 7.1 days (range 5-18 days). All alive patients were free from recurrence after a mean follow-up of 45 months (range 11-72 months). CONCLUSION Laparoscopic spleen-preserving distal pancreatectomy is safe and feasible for the management of benign insulinomas. Definition of the tumor with preoperative imaging and laparoscopic ultrasound is essential to achieve high cure rate with minimal conversion.

Abstract
Tumor-induced hypoglycemia (TIH) is a rare clinical entity that may occur in patients with diverse kinds of tumor lineages and that may be caused by different mechanisms. These pathogenic mechanisms include the eutopic insulin secretion by a pancreatic islet β-cell tumor, and also the ectopic tumor insulin secretion by non-islet-cell tumor, such as bronchial carcinoids and gastrointestinal stromal tumors. Insulinoma is, by far, the most common tumor associated with clinical and biochemical hypoglycemia. Insulinomas are usually single, small, sporadic, and intrapancreatic benign tumors. Only 5-10% of insulinomas are malignant. Insulinoma may be associated with the multiple endocrine neoplasia type 1 in 4-6% of patients. Medical therapy with diazoxide or somatostatin analogs has been used to control hypoglycemic symptoms in patients with insulinoma, but only surgical excision by enucleation or partial pancreatectomy is curative. Other mechanisms that may, more uncommonly, account for tumor-associated hypoglycemia without excess insulin secretion are the tumor secretion of peptides capable of causing glucose consumption by different mechanisms. These are the cases of tumors producing IGF2 precursors, IGF1, somatostatin, and glucagon-like peptide 1. Tumor autoimmune hypoglycemia occurs due to the production of insulin by tumor cells or insulin receptor autoantibodies. Lastly, massive tumor burden with glucose consumption, massive tumor liver infiltration, and pituitary or adrenal glands destruction by tumor are other mechanisms for TIH in cases of large and aggressive neoplasias.

Abstract
BACKGROUND No consensus exists as to whether laparoscopic treatment for pancreatic insulinomas (PIs) is safe and feasible. The aim of this meta-analysis was to assess the feasibility, safety, and potential benefits of laparoscopic approach (LA) for PIs. The abovementioned approach is also compared with open surgery. METHODS A systematic literature search (MEDLINE, EMBASE, Cochrane Library, Science Citation Index, and Ovid journals) was performed to identify relevant articles. Articles that compare the use of LA and open approach to treat PI published on or before April 30, 2013, were included in the meta-analysis. The evaluated end points were operative outcomes, postoperative recovery, and postoperative complications. RESULTS Seven observational clinical studies that recruited a total of 452 patients were included. The rates of conversion from LA to open surgery ranged from 0%-41.3%. The meta-analysis revealed that LA for PIs is associated with reduced length of hospital stay (weighted mean difference, -5.64; 95% confidence interval [CI], -7.11 to -4.16; P < 0.00001). No significant difference was observed between LA and open surgery in terms of operation time (weighted mean difference, 2.57; 95% CI, -10.91 to 16.05; P = 0.71), postoperative mortality, overall morbidity (odds ratio [OR], 0.64; 95% CI, 0.35-1.17; P = 0.14], incidence of pancreatic fistula (OR, 0.86; 95% CI, 0.51-1.44; P = 0.56), and recurrence of hyperglycemia (OR, 1.81; 95% CI, 0.41-7.95; P = 0.43). CONCLUSIONS Laparoscopic treatment for PIs is a safe and feasible approach associated with reduction in length of hospital stay and comparable rates of postoperative complications in relation with open surgery.

Abstract
PURPOSE Laparoscopic distal pancreatectomy (LDP) is a reliable and safe operation for selected patients with benign and low-grade malignant lesions in the body and tail of the pancreas. However, its application for malignant disease has been rarely reported. The aim of this study is to analyze postoperative outcomes of the patients with a diagnosis of benign or borderline malignancy, who were postoperatively diagnosed as malignancy after LDP. METHODS From January 2005 to March 2011, LDP was performed on 88 patients, and 11 were subsequently diagnosed as malignancy in postoperative pathologic reports. A retrospective analysis of the clinical outcomes of these 11 patients was conducted. RESULTS The patients were 4 men and 7 women with a median age of 68 years (range, 29 to 83 y). The postoperative diagnoses were 5 with ductal adenocarcinoma, 3 with invasive intraductal papillary mucinous neoplasm, 1 with mucinous cystadenocarcinoma, 1 with neuroendocrine carcinoma, and 1 with pancreas metastasis from a renal cell carcinoma. The median operation time was 180 minutes (range, 80 to 325 min), and the median estimated blood loss was 200 mL (range, 150 to 500 mL). There were no open conversions. Four (36%) patients experienced complications: intra-abdominal fluid collection (2), spleen infarction (1), and enterocutaneous fistula (1). The median postoperative hospital stay was 11 days (range, 6 to 18 d). All the patients were considered to have curative resection (R0), postoperatively. During the median follow-up period of 30 months (range, 3 to 58 mo), 1 patient was found to have liver metastasis, which had been present and misdiagnosed as benign hemangioma on preoperative diagnostic workup. This patient died 1 year after LDP. Another patient was found to have liver metastasis 30 months after LDP. The patient was treated with radiofrequency ablation, and he was still alive 60 months postoperatively. The remaining patients were alive without any recurrent disease. CONCLUSIONS The postoperative outcomes of the patients, who were diagnosed postoperatively as having a malignant pancreatic disease, are acceptable.

Abstract
Pancreatic neuroendocrine tumors (PNETs) are rare neoplasms. They are clinically diverse and divided into functioning and nonfunctioning disease, depending on their ability to produce symptoms due to hormone production. Surgical resection is the only curative treatment and remains the cornerstone therapy for this patient group, even in patients with advanced disease. Over the last decade there has been a noticeable trend towards more aggressive surgery as well as more minimally invasive surgery in patients with PNETs. This has resulted in improved long-term survival in patients with locally advanced and metastatic disease treated aggressively, as well as shorter hospital stays and comparable long-term outcomes in patients with limited disease treated minimally invasively. There are still controversies related to issues of surgical treatment of PNETs, such as to what extent enucleation, lymph node sampling, and vascular reconstruction are beneficial for the oncologic outcome. Histopathologic tumor classification is of high clinical importance for treatment planning and prognostic evaluation of patients with PNETs. A constant challenge, which relates to the treatment of PNETs, is the lack of an internationally accepted histopathological classification system. This paper reviews current issues on the surgical treatment of sporadic PNETs with specific focus on surgical approaches and tumor classification.

Abstract
Schwannomas are benign tumors that arise from neural sheath Schwann cells. Solitary benign schwannoma is generally located in the head and neck and is a rare neoplasm among the tumors of the retroperitoneal space. Reports of laparoscopic excision of retroperitoneal schwannomas have recently been on the increase. However, few cases of single-port laparoscopic excision of these tumors have been reported. Moreover, there are no reports of single-port excision of schwannomas attached to the body of pancreas and around the splenic vessels. This is the first report of a schwannoma lying adjacent to the body of the pancreas between the splenic artery and vein that was excised by single-port laparoscopic surgery. The most notable aspect of our procedure is the use of bipolar forceps. Single-port laparoscopic excision using bipolar forceps is a feasible and safe procedure for retroperitoneal solitary tumors, even when they are close to the splenic artery and vein.

Abstract
BACKGROUND Non-functional endocrine pancreatic tumours (NPT) of more than 2 cm have an increased risk of malignancy. The aim of the present study was: (i) to define the guidelines for laparoscopic enucleation (LapEn) in patients with a non-functional NPT ≤3 cm in diameter; (ii) to evaluate pancreas-related complications; and (iii) to present the long-term outcome. METHODS Between April 1998 and September 2010, 30 consecutive patients underwent laparoscopic surgery for a non-functional NPT (median age 56.5 years, range 44-83). Only 13 patients with tumours ≤3 cm in size underwent LapEn. Local lymph node dissection to exclude lymph node involvement was performed in all patients. RESULTS The median tumour size, operative time and blood loss were 2.8 cm (range 2.8-3), 130 min (range 90-280) and 220 ml (range 120-300), respectively. A pancreatic fistula occurred in five patients: International Study Group of Pancreatic Fistula (ISGPF) A in two patients and ISGPF B in three patients. The median follow-up was 48 months (12-144). Three patients with well-differentiated carcinoma are free of disease 2, 3 and 4 years after LapEn and a regional lymphadenectomy. One patient, 5 years after a LapEn, presented with lymph node and liver metastases. CONCLUSIONS The present study confirms the technical feasibility and acceptable morbidity associated with LapEn. Intra-operative lymph node sampling and frozen-section examination should be performed at the time of LapEn; when a malignancy is confirmed, oncologically appropriate lymph node dissection should be performed.

Abstract
Insulinomas constitute about 25% of endocrine pancreatic tumors. Laparoscopic surgery is the treatment of choice. However, pancreas-related complications rate is very high, even in experienced hands, ranging up to 37%. Alternative procedures such as embolization with trisacryl have not been accepted by the surgical community. Image-guided robotic radiosurgery or stereotactic radiosurgery (CyberKnife) is a minimally invasive procedure delivering large doses of ionizing radiation to a well-defined target. CyberKnife radiosurgery is successfully used in brain cancer, lung cancer, prostate cancer, liver metastases, kidney cancer, and pancreatic cancer. The authors present the first case to their knowledge of a benign functioning insulinoma successfully treated by a CyberKnife technique with a 3-year follow-up.

Abstract
The pseudopapillary tumor of the pancreas (or Frantz's tumor) is a rare exocrine pancreatic tumor with a low degree of malignancy. It occurs more frequently among women between 20 and 40 years of age and in the Asian population. This tumor is rarer in the pediatric population. The symptoms are subtle, the most striking being pain and an abdominal mass. Pathologically, the tumor is usually well circumscribed with regions of necrosis, hemorrhage and cystic degeneration. A thick, fibrous capsule is often present. The low grade of malignancy of this tumor with a fibrous capsule led to perform a surgical resection. The localization and local invasion determine the surgical technique. Despite its potential for local infiltration and metastatic disease (up to 15% confined often to the liver), the prognosis is favorable after a surgical resection with correct margins. Long follow-up is necessary to detect a possible recurrence, even late.

Abstract
BACKGROUND Laparoscopic insulinoma resection (LIR) for sporadic disease is increasingly supported as a feasible and safe operation in small series of patients. To determine whether LIR is an acceptable alternative to the open operation, it is necessary to compare LIR to historical controls. The purpose of this study was to identify the skills and technology needed for LIR and establish outcome standards. METHODS A database of patients with benign sporadic insulinoma who underwent an open procedure at the Mayo Clinic was reviewed for demographics, imaging, operative/pathology reports, and outcomes. Outcomes were compared to a world-wide meta-analysis of patients who had undergone LIR reported in the English literature between 1996 and 2009. RESULTS Two hundred fifteen patients underwent a primary open operation for benign sporadic insulinoma. Solitary tumors were found in 97%. Meta-analysis identified 232 patients who underwent LIR. The open and LIR groups underwent comparable operations that included enucleations (64 vs. 68%) and distal pancreatectomies (28 vs. 35%) (p = 0.06). The mean estimated blood loss, operating time, and length of stay were comparable between the open and LIR groups (p = NS). Pancreatic fistula occurred more often in the LIR group (24 vs. 11%, p < 0.05). A curative operation was performed in 98% of control patients and in 99% of the LIR group (p = NS). CONCLUSIONS Multiple insulinomas are rare and a focused resection guided by imaging may be performed. LIR is associated with an increased incidence of pancreatic fistula. Success of LIR will depend on accurate multimodality preoperative imaging, skilled use of lap-US to replace palpation for localization, and safe methods to dissect the tumor adjacent to the pancreatic duct.

Abstract
Recently, increasing number of manuscripts - original articles and case reports have attempted to provide evidence of the forays of minimal access surgery into pancreatic diseases. Many, based on the lack of Level I evidence, still believe that laparoscopy in pancreatic surgery is experimental. This article attempts to look into data exploring the existing use of minimally invasive surgery in pancreatic disease to answer a vital question - what does the evidence say on the current status of laparoscopic surgery in pancreatic tumors.

Abstract
We describe an unusual case of hypoglycemic syndrome in a 69-year old woman with a proinsulin-only secreting pancreatic endocrine adenoma. The clinical history was highly suggestive of an organic hypoglycemia, with normal or relatively low insulin concentrations and elevated proinsulin levels. Magnetic resonance and computed tomography of the abdomen showed a 1 cm pancreatic nodule and multiple accessory spleens. The diagnosis was confirmed by selective angiography, showing location and vascularization of the nodule, despite no response to intra-arterial calcium. After resection, the hypoglycemic syndrome resolved. The surgical specimen was comprised of a neuroendocrine adenomatous tissue with high proinsulin immunoreactivity. Study of this unusual case of proinsulinoma underlines (i) the need to assay proinsulin in patients with hypoglycemia and normal immunoreactive insulin, (ii) the differential diagnosis in the presence of accessory spleens, (iii) the unresponsiveness to intra-arterial calcium stimulation, and (iv) the extensive evaluation needed to reach a final diagnosis.

Abstract
BACKGROUND The use of a laparoscopic approach in the treatment of insulinomas is increasing. This retrospective study aimed to evaluate the authors' experience with laparoscopic surgery for benign pancreatic insulinomas and to compare the results for a laparoscopic approach versus an open approach. METHODS From January 2000 to December 2009, data were collected retrospectively from 89 patients who underwent resection of pancreatic insulinoma via either laparoscopy (n = 43) or laparotomy (n = 46). Clinical data, tumor features, and intra- and postoperative characteristics were analyzed. RESULTS The operation time, blood loss, and complication rate did not differ significantly between the laparoscopic and open approach groups. In the laparoscopic group, the time required to achieve recovery of gastrointestinal function and postoperative oral intake was significantly shorter in the laparotomy group, as was the hospital stay. By the end of the follow-up period, 85 (95.5%) of the 89 patients were symptom free. CONCLUSIONS Laparoscopic surgery is a safe procedure for patients with benign insulinomas. The complication rates are comparable with those for laparotomy procedures. Relative to open operations, laparoscopic pancreas operations are associated with a more rapid postoperative recovery.

Abstract
BACKGROUND Advances in operative techniques and technology have facilitated laparoscopic distal pancreatectomy (LDP) and laparoscopic pancreaticoduodenectomy (LPD). METHODS All distal pancreatectomies were attempted laparoscopically, while selected patients underwent LPD. The literature was systematically reviewed. RESULTS Between 2002 and 2008, 21 patients underwent LDP (n=14) or LPD (n = 7). The mean operating time, blood loss, and hospital stay after LDP were 265 min, 262 ml, and 7.7 days, respectively, and after LPD they were 628 min, 350 ml, and 11.1 days, respectively. The conversion, morbidity, pancreatic fistula, readmission, reoperation, and mortality after LDP were 7.1, 35.7, 28.4, 28.4, 0, and 7.1% respectively, and after LPD they were 0, 28.6, 14.3, 28.6, 0, and 0% respectively. The literature review identified 987 LDP and 126 LPD. Most LDP were for benign disease (83.9%) while most LPD were for malignancy (91.5%). The mean operating time, morbidity, pancreatic fistula, mortality, and hospital stay after LDP were 221.5 min, 24.7%, 16.4%, 0.4%, and 7.7 days, respectively, and after LPD they were 448.3 min, 28.6%, 11.6%, 2.1%, and 16 days, respectively. CONCLUSION LDP, particularly for benign disease and low-grade malignancy, is increasingly becoming the gold standard approach in experienced hands. In selected patients, LPD is feasible and safe. Long-term follow-up data are needed.

Abstract
The rapid growth of minimally invasive technology and experience in recent decades has revolutionized many aspects of oncologic surgery. Adoption of laparoscopic pancreatectomy has been slow due to the inherent anatomic complexity of pancreatic surgery, as well as concerns of perioperative complications and compromised oncologic results. With increasing surgeon experience and growing data, laparoscopic pancreatic resection is generating considerable attention and enthusiasm. This article provides an overview of laparoscopic pancreatic tumor surgery with respect to tumor biology and technical approaches. Current applications of laparoscopic approaches to left pancreatectomy, tumor enucleation, central pancreatectomy, and pancreaticoduodenectomy for treatment of pancreatic tumors are considered in light of available evidence demonstrating feasibility, safety, and oncologic efficacy. Future directions in minimally invasive pancreatic surgery are explored.

Abstract
A laparoscopic resection is a new treatment for pancreatic tumors. Articles by surgeons who are writing about their first experience in carrying out this treatment have appeared in the literature, reporting that laparoscopic surgery can be used for the treatment of pancreatitis, benign lesions, and solid tumors. This is a study of three patients with pancreatic tumors who were treated by means of a laparoscopic distal pancreatic resection with preservation of the spleen and splenic vessels. In three cases a laparoscopic distal resection was performed for the tumor. The histologic examinations showed one insulinoma and two mucinous cystadenomas. No patient suffered from intra- or postoperative complications. A laparoscopic resection of the distal pancreas is a new alternative for the treatment of pancreatic tumors. This method takes advantage of the benefits of minimally invasive surgery.

Abstract
PURPOSE Solid pseudo-papillary tumors (SPT) are rare pancreatic neoplasms of low-malignant potential occurring mainly in young women. The purpose of this report is to describe our experience with laparoscopic management of these tumors with 4-year follow-up. METHODS Three children with SPT were admitted to two hospitals in Paris, France, between February 2000 and December 2006. Diagnosis or treatment was carried out using laparoscopic techniques (biopsy and resection in one case and biopsy only in two). Long-term follow-up data were collected. RESULTS All three patients presented recurrences within 3 years after resection, i.e., disseminated peritoneal recurrence in two patients and local recurrence in one. The two patients with peritoneal recurrences were treated by surgical resection and chemotherapy. The patient with local recurrence could not be treated due to contraindicating local factors. All three patients were alive at the time of this writing. CONCLUSION This is the first report describing long-term follow-up after laparoscopic management of SPT. All three patients developed recurrences. These poor results contrast sharply with the low risk of local or disseminated recurrence after open laparotomy without chemotherapy that has been considered as the treatment of choice up to now. Recurrences after laparoscopic management may have been due to diffusion of tumor cells caused by gas insufflation especially during biopsy. Laparoscopic biopsy should not be performed in patients presenting SPT.

Abstract
In recent years, improved laparoscopic skill sets have expanded surgical management of pancreatic disease to encompass pancreatic resection, tumor enucleation, debridement, and drainage. With the aid of radiologically guided drainage catheters, necrosectomy for acute pancreatitis can be delayed and accomplished laparoscopically in a select patient population. Pancreatic pseudocysts from chronic pancreatitis can now be approached via minimally invasive strategies, including emerging combined laparoscopic procedures and natural orifice transluminal endoscopic surgery. It is clear that laparoscopic pancreaticoduodenectomy is possible in experienced hands; pancreatic neoplasms in the body and tail are more suitable for laparoscopic procedures because distal pancreatic resection requires no reconstruction of the biliary or enteric tract. Laparoscopic staging of pancreatic tumors has decreased as preoperative radiographic imaging becomes more sensitive. Similarly, laparoscopic palliative procedures have decreased because of the emergence of other minimally invasive options for relieving gastric outlet obstruction and biliary obstruction. Nonetheless, major advances in minimally invasive pancreatic surgery will continue as technology and skill sets advance.

Abstract
BACKGROUND Pancreatic resection is associated with a significant morbidity. Efforts to reduce hospital stay and enhance recovery have seen the introduction of minimally invasive surgical techniques. This article reviews the current published literature on the safety and efficacy of minimally invasive surgery of the pancreas. METHODS An electronic search of the PubMed and Embase databases was performed from 1996 to May 2008 to identify all relevant publications; studies meeting predefined inclusion criteria were retrieved and analyzed using a standardized protocol. Data on the safety and efficacy of minimally invasive surgery of the pancreas were recorded and analyzed. RESULTS Of 565 abstracts reviewed, 39 studies were identified as eligible for inclusion. There were 37 case series and two case control studies. Compared with open pancreatic surgery, minimally invasive pancreatic resection is similar in terms of morbidity and mortality. Blood loss and length of stay are decreased. CONCLUSIONS Laparoscopic distal pancreatic resection and enucleation of insulinoma appear to be safe procedures with reduced hospital stay, though morbidity remains significant. The evidence for laparoscopic pancreaticoduodenectomy is in its infancy, but the authors feel it is unlikely that many centers will achieve sufficient case load to make the introduction of minimally invasive resection feasible.

Abstract
BACKGROUND Laparoscopic approach has been increasingly used in the treatment of pancreatic benign diseases. This report evaluates our experience with laparoscopic surgery for pancreatic insulinomas. METHODS Between July 2000 and December 2007, laparoscopic pancreatectomy was attempted in 29 consecutive patients with insulinomas. The localization of tumors, operating characteristics, and clinical outcomes were analyzed. RESULTS Tumors were precisely localized in 28 of 29 (96.6%) patients by a combination of preoperative imaging techniques and intraoperative ultrasonography. Laparoscopic pancreatectomy was successfully performed in 26 patients, including enucleation (n = 14), hand-assisted enucleation (n = 2), and distal pancreatectomy with (n = 9) or without (n = 1) spleen preservation. Two conversions to open procedure were required because of unfavorable locations of the tumors. The pancreatic fistula occurred in four patients who underwent tumor enucleation. The median hospital stay was 5.5 days (range, 3-18 days) after laparoscopic procedure. Twenty-eight patients with pancreatic resection were free of symptoms and remained normoglycemic after a median follow-up period of 19 months (range, 10-36 months). CONCLUSION Laparoscopic pancreatic resection is a feasible and safe procedure for patients with insulinomas. Further studies are required to evaluate the potential application of the hand-assisted approach for tumors located at anatomically unfavorable positions.

Am J Surg 2009; 197:e51-3. [PMID: 19249742 DOI: 10.1016/j.amjsurg.2008.06.045] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2008] [Revised: 06/25/2008] [Accepted: 06/25/2008] [Indexed: 01/27/2023]
Abstract
The posterior aspect of the pancreatic head has proven to be a technically demanding region to approach laparoscopically. Previously, this region was approached through the gastrocolic ligament with the patient in a left semilateral position. We believe that this makes the laparoscopic approach to the posterior pancreatic head extremely difficult. In the technique presented here, which has been successfully used in 4 patients, the patient was in full left lateral position, and Nathanson retractors were used to retract the liver and right kidney. This allowed full exposure of the second part of the duodenum before any major dissection. The duodenum was then Kocherized, and the posterior aspect of the pancreatic head, along with the inferior vena cava, left renal vein, and aorta, was exposed. We describe here a safe and feasible laparoscopic method for access to and management of lesions related to the posterior aspect of the pancreatic head.

Abstract
BACKGROUND Pancreatic resection is associated with a significant morbidity. Efforts to reduce hospital stay and enhance recovery have seen the introduction of minimally invasive surgical techniques. This article reviews the current published literature on the safety and efficacy of minimally invasive surgery of the pancreas. METHODS An electronic search of the PubMed and Embase databases was performed from 1996 to May 2008 to identify all relevant publications; studies meeting predefined inclusion criteria were retrieved and analyzed using a standardized protocol. Data on the safety and efficacy of minimally invasive surgery of the pancreas were recorded and analyzed. RESULTS Of 565 abstracts reviewed, 39 studies were identified as eligible for inclusion. There were 37 case series and two case control studies. Compared with open pancreatic surgery, minimally invasive pancreatic resection is similar in terms of morbidity and mortality. Blood loss and length of stay are decreased. CONCLUSIONS Laparoscopic distal pancreatic resection and enucleation of insulinoma appear to be safe procedures with reduced hospital stay, though morbidity remains significant. The evidence for laparoscopic pancreaticoduodenectomy is in its infancy, but the authors feel it is unlikely that many centers will achieve sufficient case load to make the introduction of minimally invasive resection feasible.

Abstract
Although the role of minimally invasive techniques in pancreatic surgery remains controversial, resection of the left pancreas for benign or endocrine lesions has been universally adopted as a routine technique over the last few years. This study was undertaken to assess feasibility and safety of minimal access resections of distal pancreas in benign, endocrine, and malignant diseases. Operative time, conversion rate, adequacy of dissection, respect for oncologic principles, morbidity rate, and short-term outcomes were analyzed. From the years 2002 to 2007, 14 patients affected by pancreatic neoplasm of body/tail region were approached by minimally invasive technique. Nine patients were affected by malignant neoplasms and distal splenopancreatectomy was successfully achieved by laparoscopy in 6. Five patients were affected by endocrine neoplasms; distal pancreatectomy with preservation of spleen and splenic vessels was achieved laparoscopically in 3, whereas 2 needed conversion to laparotomy. Four patients developed pancreatic leak after transection by linear cutting stapler plus oversewing, whereas no leak was observed within 30 days from surgery after transection by linear stapler with Seamguard reinforcement of the staple line (P<0.05 with Fisher exact test).

Abstract
Pancreatic endocrine tumors (PETs) have long fascinated clinicians and investigators despite their relative rarity. Their clinical presentation varies depending on whether the tumor is functional or not, and also according to the specific hormonal syndrome produced. Tumors may be sporadic or inherited, but little is known about their molecular pathology, especially the sporadic forms. Chromogranin A appears to be the most useful serum marker for diagnosis, staging, and monitoring. Initially, therapy should be directed at the hormonal syndrome because this has the major initial impact on the patient's health. Most PETs are relatively indolent but ultimately malignant, except for insulinomas, which predominantly are benign. Surgery is the only modality that offers the possibility of cure, although it generally is noncurative in patients with Zollinger-Ellison syndrome or nonfunctional PETs with multiple endocrine neoplasia-type 1. Preoperative staging of disease extent is necessary to determine the likelihood of complete resection although debulking surgery often is believed to be useful in patients with unresectable tumors. Once metastatic, biotherapy is usually the first modality used because it generally is well tolerated. Systemic or regional therapies generally are reserved until symptoms occur or tumor growth is rapid. Recently, a number of newer agents, as well as receptor-directed radiotherapy, are being evaluated for patients with advanced disease. This review addresses a number of recent advances regarding the molecular pathology, diagnosis, localization, and management of PETs including discussion of peptide-receptor radionuclide therapy and other novel antitumor approaches. We conclude with a discussion of future directions and unsettled problems in the field.

Abstract
Laparoscopic approaches are increasingly used in pancreatic surgery. In the treatment of neuroendocrine tumors (NETs) of the pancreas, enucleation is one of the recommended surgery. Although many clinical experiences have reported the safety and efficacy of laparoscopic enucleation of functioning NETs, such as insulinomas, few reports have explored such treatment for non-functioning NETs. Here, we present a case of 70-year old female patient who underwent successful laparoscopic enucleation of a nonfunctioning NET located in the body of the pancreas.

Abstract
Since the first reports with laparoscopic resection of islet cell tumors in 1996, the experience worldwide is still limited, with only short-term outcomes available. Some have suggested that a malignant tumor is a contraindication to laparoscopic resection. Aim The aim of this study was to evaluate the feasibility, safety, and long-term outcome of the laparoscopic approach in patients with functioning, nonfunctioning, or overt malignant pancreatic neuroendocrine tumor (PNT). To our knowledge this is the largest single-institution series on this subject to date. Patients and methods A total of 49 consecutive patients (43 women, 6 men; mean age 58 years, range 22-83 years) underwent laparoscopic pancreatic surgery (LPS) from April 1998 to June 2007. Preoperative localization was done by computed tomography, magnetic resonance imaging, endoscopic ultrasonography, and Octreoscan imaging. Other than 9 PNTs localized in the head of the pancreas, all tumors were located in the left pancreas. Malignancy was diagnosed based on the presence of lymph nodes or liver metastasis. There were 33 patients with functioning tumors: 4 with gastrinomas (mean size 1.2 cm), 1 with a glucagonoma (4 cm), 3 with vipomas (3.2 cm), 2 with carcinoids (5.2 cm), 20 with sporadic insulinomas (1.4 cm), 2 with insulinoma/multiple endocrine neoplasia type 1 (MEN-1) (4.4 cm), and 1 with a malignant insulinoma (13 cm). Sixteen patients had a nonfunctioning tumor (mean size 5 cm). The following techniques were performed: laparoscopic spleen-preserving distal pancreatectomy (Lap SPDP), laparoscopic distal pancreatectomy with splenectomy (Lap SxDP) and laparoscopic enucleation (Lap En)/laparoscopic excision (Lap E). Lymph node dissection was performed when malignancy was suspected (Strasberg s technique). Evaluation criteria included operative and postoperative factors, pathologic data including R0 or R1 resection (the pancreatic transection margin and all transection margins on the specimen were inked). Long-term outcomes were analyzed by tumor recurrence and patient survival. Results Four cases (8.2%) were converted to open surgery. Overall, Lap SPDP, Lap SxDP, and Lap En/Lap E were performed in 15 (33.3%), 8 (17.8%), and 22 (48.9%) patients, respectively. The operative time and blood loss was significantly lower in the Lap En group compared with the other laparoscopic techniques. The group of patients with malignant tumors undergoing Lap SxDP had a longer operating time and greater blood loss compared with the other distal pancreatectomy (Lap DP) techniques. Overall, the postoperative complications were significantly higher in the Lap En group (42.8%) than in the Lap DP (Lap SPDP+Lap SxDP) group (22%). These complications were mainly pancreatic fistula: 8.7% after Lap DP and 38% after Lap En. The overall morbidity was significantly higher after Lap SPDP (26.7%) than after Lap SxDP (12.5%) owing to the occurrence of splenic complications in the Lap SPDP group without splenic vessel preservation two of seven (28.5%). The means and ranges of hospital stay after Lap SPDP, Lap SxDP, and Lap En/Lap E were 5.9 (5-14), 7.5 (5-12), and 5.5 (5-7) days, respectively (NS). Pathology examination of the specimen showed R0 resection in all patients with malignant PNT. The mean time to resumption of previous activities for patients undergoing Lap DP or Lap En was 3 weeks. There were no postoperative (30 days) or hospital deaths. Conclusions This series demonstrates that LPS is feasible and safe in benign-appearing and malignant neuroendocrine pancreatic tumors (NEPTs). The benefits of minimally invasive surgery were manifest in the short hospital stay and acceptable pancreas-related complications in high-risk patients. LPS can achieve negative tangential margins in a high percentage of patients with malignant tumors. Although surgical cure is rare in malignant NEPTs, significant long-term palliation can be achieved in a large proportion of patients with an aggressive surgical approach.

Abstract
PURPOSE OF REVIEW Pancreatic neuroendocrine tumors are rare neoplasms often associated with a clinical syndrome. Their rarity makes a comprehensive study difficult at any single institution, while their uniqueness makes them desirable for investigation. This review summarizes recent information and advancements concerning pancreatic neuroendocrine tumor diagnosis, imaging characteristics, treatment algorithms, and staging. RECENT FINDINGS Insulinomas and gastrinomas comprise the majority of functional pancreatic neuroendocrine tumors. Advances in their identification and diagnostic evaluation, imaging techniques, and treatment algorithms are presented. Furthermore, a new staging classification system has been proposed which may significantly improve the ability to conduct future multi-institutional investigations on pancreatic neuroendocrine tumors. SUMMARY Although rare, a thorough understanding of pancreatic neuroendocrine tumors is essential for all physicians due to the wide variety of symptoms with which patients present. Currently, patients are often misdiagnosed for extended periods of time. This review summarizes the recently published literature about diagnosis, imaging, treatment, and staging of pancreatic neuroendocrine tumors.

Abstract
Insulinomas continue to pose a diagnostic challenge to physicians, surgeons and radiologists alike. Most are intrapancreatic, benign and solitary. Biochemical diagnosis is obtained and imaging techniques to localize lesions continue to evolve. Surgical resection is the treatment of choice. Despite all efforts, an occult insulinoma (occult insulinoma refers to a biochemically proven tumor with indeterminate anatomical site before operation) may still be encountered. New localization preoperative techniques decreases occult cases and the knowledge of the site of the mass before surgery allows to determine whether enucleation of the tumor or pancreatic resection is likely to be required and whether the tumor is amenable to removal via a laparoscopic approach. In absence of preoperative localization and intraoperative detection of an insulinoma, blind pancreatic resection is not recommended.

Abstract
BACKGROUND Laparoscopic surgery for pancreatic disease has gained increasing popularity. A laparoscopic distal pancreatectomy is technically simple and has been adopted as the preferred method in many centers. However, there is limited information on the outcomes of the laparoscopic surgery compared with open surgery. Therefore, this study aimed to investigate the clinical outcomes of laparoscopic distal pancreatectomy and to evaluate its efficacy compared with open distal pancreatectomy. METHODS From February 1995 to March 2006, 31 patients underwent laparoscopic distal pancreatectomy, and 167 patients underwent open distal pancreatectomy at Seoul National University Hospital and Bundang Seoul National University Hospital. A case-control design was used with 2:1 matching to compare laparoscopic surgery with open surgery. Among 167 patients who underwent open distal pancreatectomy, 62 patients whose age, gender, and pathology were similar to those of patients who underwent laparoscopic surgery were selected for this study. The operation time, intraoperative transfusion requirements, duration of postoperative hospitalization, complications, mortality, recurrence, and hospital charges were analyzed. RESULTS There were no significant differences in operation time, rate of intraoperative transfusions, complications, recurrence, or mortality between the two groups. Laparoscopic distal pancreatectomy was associated with a statistically significant shorter hospital stay (11.5 days vs 13.5 days; p = 0.049), but with more expensive hospital charges than open distal pancreatectomy (p < 0.01). CONCLUSION Laparoscopic distal pancreatectomy is a clinically safe and effective procedure for benign and borderline pancreatic tumors.

Abstract
Incidental, nonfunctional pancreatic endocrine tumors (PET) are observed with increasing frequency. Most are insulinomas. Endoscopic ultrasound with fine-needle aspiration plays a significant role in the localization and tissue diagnosis of PET. Establishing PET behavior as aggressive or indolent remains challenging especially preoperatively. Newer techniques including DNA and micro-RNA analysis may play a role in this arena. Small benign PET may be enucleated or removed laparoscopically. Surgery is the mainstay of treating advanced disease including those with metastases and Zollinger-Ellison syndrome. The management of multiple endocrine neoplasia type 1 continues to be a challenge, including treating symptoms, targeted resections, and close observation. Diagnosis, management, and prognostication of PET are under evolution and a number of changes in these fronts are anticipated.
