ABSTRACT: BACKGROUND/OBJECTIVES: It is often difficult to determine an adequate resection line during pancreatectomy for intraductal papillary mucinous neoplasm involving the main pancreatic duct during partial pancreatectomy. The aim of this study was to evaluate the usefulness of improved peroral pancreatoscopy using SpyGlass-DS METHODS: We collected and retrospectively analyzed clinicopathological data from seven consecutive patients who underwent preoperative assessment of intraductal papillary mucinous neoplasm involving the main duct using SpyGlass-DS RESULTS: Good imaging quality of the intraductal protruding lesion was obtained in all seven patients, and only one adverse event was noted wherein a patient had mild pancreatitis. Six patients underwent pancreatectomy. In one patient, masked-type concomitant pancreatic ductal adenocarcinoma and low-length dysplastic lesion was found near the surgical margin, which was not detected by preoperative imaging modalities including SpyGlass-DS CONCLUSIONS: SpyGlass-DS

2 Article Prediction of Pancreatic Fistula by Preoperatively Assessable Factors; Retrospective Review of Unified Operations by Single Surgeon. 2014

Nakamura, Masafumi / Shindo, Koji / Ideno, Noboru / Ueda, Junji / Takahata, Shunichi / Nakashima, Hiroshi / Ohtsuka, Takao / Shimizu, Shuji / Oda, Yoshinao / Tanaka, Masao. · ·Hepatogastroenterology · Pubmed #26176082.

ABSTRACT: BACKGROUND/AIMS: This retrospective study was conducted to find preoperatively assessable risk factors for postoperative pancreatic fistula (POPF) in patients undergoing laparoscopic distal pancreatectomy (LDP) using a slow compression method with a stapler, which we call pen-firing compression (PFC). METHODOLOGY: Fifty-two patients underwent LDP, of whom 42 underwent PFC for pancreatic division using a stapler. The relationship between preoperatively assessable factors and the incidence of clinical POPF was statistically analyzed. RESULTS: Overall rate of POPF was 7.1% in 42 patients. Univariate analysis showed that greater BMI (p = 0.004) and thicker pancreatic stump (0.0022) were significant risk factors for POPF. BMI and stump thickness remained significant (P < 0.0001, P < 0.0001) by multivariate analysis. Cutoff points estimated by ROC curve were 27 kg/m2 for BMI and 27 mm for stump thickness. CONCLUSIONS: High BMI value and thick pancreatic stump are significant risk factors for POPF after LDP. Alternative treatment of the pancreatic stump may prevent POPF in high-risk patients.

3 Article Laparoscopic surgery is applicable for larger mucinous cystic neoplasms of the pancreas. 2014

Ohtsuka, Takao / Takahata, Shunichi / Takanami, Hideki / Ueda, Junji / Mizumoto, Kazuhiro / Shimizu, Shuji / Tanaka, Masao. ·Department of Surgery and Oncology, Graduate School of Medical Sciences, Kyushu University, 3-1-1 Maidashi, Higashi-ku, Fukuoka, 812-8582, Japan. ·J Hepatobiliary Pancreat Sci · Pubmed #24027109.

ABSTRACT: BACKGROUND: Mucinous cystic neoplasms (MCN) of the pancreas frequently develop in the distal pancreases of young women. Laparoscopic surgery can enhance cosmetic benefits and ease of surgery. This study assessed the feasibility of laparoscopic surgery for MCN. METHODS: The medical records of 21 patients pathologically diagnosed with benign MCN after laparoscopic resection were reviewed. Clinical data were compared in the 11 patients with tumors ≥ 45 mm (large tumor group) and the 10 patients with tumors < 45 mm (small tumor group). RESULTS: Laparoscopic resection was completed in all patients, including distal pancreatectomy with (n = 9) and without (n = 11) spleen preservation and enucleation for pancreatic head lesion (n = 1). Operation time, blood loss, postoperative morbidity, and hospital stay were similar in the two groups. Spleen-preserving pancreatectomy could be more frequently completed in the small MCN group (P = 0.02). No recurrence was observed during a median follow-up period of 12 months. CONCLUSIONS: Laparoscopic surgery can be completed in all patients with benign MCN, even those with large tumors, and patients with small MCN can get the additional benefit of spleen preservation.

4 Article [Surgical treatment of gastroentero-pancreatic neuroendocrine tumor]. 2013

Ohtsuka, Takao / Takahata, Shunichi / Ueda, Junji / Ueki, Takashi / Nagai, Eishi / Mizumoto, Kazuhiro / Shimizu, Shuji / Tanaka, Masao. ·Dept. of Surgery and Oncology, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan. ·Gan To Kagaku Ryoho · Pubmed #23863724.

ABSTRACT: The treatment of choice for gastroentero-pancreatic neuroendocrine tumor(NET)is resection. Because it is difficult to determine the histological grade of NET before operation, the treatment strategy is usually made based on an imaging study including the tumor's size. Some selected gastrointestinal NETs are indicated for endoscopic resection, while others are resected surgically with lymph node dissection. The types of resections for pancreatic NETs vary from enucleation to pancreatectomy with or without regional lymph node dissection, based on the type of excessive hormone, tumor size, distance from the main pancreatic duct, and the presence of type 1 multiple endocrine neoplasia. Hepatic metastases are also resected, if indicated, and even in patients having unresectable metastatic lesions, multidisciplinary therapy including reduction surgery of over 90% of tumor volume might lead to a favorable prognosis. Postoperative adjuvant therapy is recommended for neuroendocrine carcinoma, while there is no evidence to support adjuvant therapy for curatively resected well-differentiated NET.
