We report an extremely rare case of adult intussusception caused by Meckel's diverticulum complicated by anisakiasis of the small intestine. A 48-year-old female was admitted to our hospital with vomiting and abdominal pain 3 days after eating raw fish. The abdomen was distended with tenderness. Computed tomography demonstrated a target-shaped mass in the ileum and wall thickness of the distal ileum. We diagnosed intussusception and performed emergency surgery. At laparotomy, intussusception was already released. Since Meckel's diverticulum was observed at 40 cm and wall thickness was observed at 20 cm from the terminal ileum, we performed partial ileal resection including these lesions. On pathology, the anisakis body was found in the resected specimen of the ileum with wall thickness. The patient was discharged 8 days after surgery.

A 44-year-old man was admitted to our hospital with abdominal pain. Enhanced abdominal computed tomography demonstrated intraperitoneal free air and fluid collection. Peritonitis due to intestinal perforation was suspected and an emergency laparotomy was performed. Exploration of the abdominal cavity confirmed perforation of the ileum at a site 20cm from the terminal ileum. Therefore, we performed partial ileal resection that included the perforation and placed an ileostomy. Histopathological examination of the ileum revealed infiltration of eosinophilic leukocytes between the submucosal and subserosal layers, compatible with the diagnosis of eosinophilic gastroenteritis.

Background: Although adjuvant gemcitabine (GEM) chemotherapy for pancreatic cancer is standard, the quality of life (QOL) in those patients is still impaired by the standard regimen of GEM. Therefore, we studied whether mild dose-intensity adjuvant chemotherapy with bi-weekly GEM administration could provide a survival benefit with acceptable QOL to the patients with pancreatic cancer., Methods: After a phase I trial, an adjuvant bi-weekly 1,000 mg/m2 of GEM chemotherapy was performed in 58 patients with pancreatic cancer for at least 12 courses (Group A). In contrast, 36 patients who declined the adjuvant bi-weekly GEM chemotherapy underwent traditional adjuvant 5FU-based chemotherapy (Group B). Careful periodical follow-ups for side effects of GEM and disease recurrence, and assessment of patients' QOL using the EORTC QOL questionnaire (QLQ-C30) and pancreatic cancer-specific supplemental module (QLQ-PAN26) were performed. Retrospectively, the degree of side effects, patients' QOL, compliance rate, disease-free survival (DFS), and overall survival (OS) in Group A were compared with those in Group B., Results: No severe side effects (higher than Grade 2 according to the common toxicity criteria of ECOG) were observed, except for patients in Group B, who were switched to the standard GEM chemotherapy. Patients' QOL was better in Group A than B (fatigue: 48.9 ± 32.1 versus 68.1 ± 36.3, nausea and vomiting: 26.8 ± 20.4 versus 53.7 ± 32.6, diarrhea: 21.0 ± 22.6 versus 53.9 ± 38.5, difficulty gaining weight: 49.5 ± 34.4 versus 67.7 ± 40.5, P < 0.05). Compliance rates in Groups A and B were 93% and 47%. There was a significant difference in the median DFS between both groups (Group A : B =12.5 : 6.6 months, P < 0.001). The median OS of Group A was prolonged markedly compared with Group B (20.2 versus 11.9 months, P < 0.005). For OS between both groups, univariate analysis revealed no statistical difference in 69-year-old or under females, and T1-2 factors, moreover, multivariate analysis indicated three factors, such as bi-weekly adjuvant GEM chemotherapy, T2 or less, and R0., Conclusions: Adjuvant chemotherapy with bi-weekly GEM offered not only the advantage of survival benefits but the excellent compliance with acceptable QOL for postoperative pancreatic cancer patients.

Background/aims: The purpose of this study was to identify basic risk factors for postoperative pancreatic fistula (POPF) after pancreaticojejunostomy., Methodology: Seventy-one patients underwent pancreaticojejunostomy with duct-to-mucosa anastomosis (DMA). Between POPF group (n=8) and non- POPF group (n=63), the following clinical parameters were compared; pancreatic texture evaluated pathologically with score, diameter of the pancreatic duct, total number of sutures, interval between sutures and the size of suture (5-0 vs. 6-0) for DMA., Results: The mean diameter of the pancreatic duct (POPF/non-POPF) was 3.0±1.4/4.2±2.0mm, total number of sutures for DMA was 6.8±1.6/7.0±2.8, whereas mean interval between sutures was 1.4±0.5/2.1±1.1mm, which failed to achieve significant difference. All cases except one that produced POPF had soft pancreas (p=0.0022). However, for the soft pancreas, the score of pancreatic texture did not achieve significant difference between POPF and non-POPF. 5-0 sutures had less chance of POPF (p=0.0035). As a result of multivariate analysis, suture size and pancreatic texture correlated with POPF., Conclusions: The suture size and pancreatic texture were risk factors for POPF. Since these factors are related to surgical techniques, gentle handling during pancreaticojejunostomy seems important.

Background: The use of stapling devices for distal pancreatectomy remains controversial, due to concerns about the development of postoperative pancreatic fistula (POPF) and hemorrhage., Methods: We report herein the usefulness of the Endo SGIA stapler (Tyco Healthcare, Norwalk, CT) for distal pancreatectomy by placing 2 triple-staggered rows, ie, 6 rows of staples in the pancreatic stump. The pancreas was divided together with both the splenic artery and vein with Endo SGIA in 7 consecutive hand-assisted laparoscopic distal pancreatectomies., Results: No patients developed clinically significant POPF or postoperative hemorrhage. None of the patients had complications that may have influenced the length of hospital stay., Conclusion: The 6-row Endo SGIA stapler allows quick and effective prevention of POPF after distal pancreatectomy.

Background: Although the clinical benefits of hand-assisted laparoscopic surgery have been shown in several procedures including colorectal resection, splenectomy and gastrectomy, efficacy and invasiveness in pancreatic surgery have not been well investigated. We assessed the clinical benefits and invasiveness of hand-assisted laparoscopic distal pancreatectomy (HALS-DP) in relation to the occurrence of post-operative systemic inflammatory response syndrome (SIRS)., Methods: Subjects comprised 8 patients underwent HALS-DP (with splenectomy, n = 7; without splenectomy, n = 1) for benign or low malignant pancreatic lesions between March 2004 and December 2005. Indications for HALS-DP consisted of mucinous cystadenoma (n = 4), endocrine tumors (n = 2), serous cystadenoma (n = 1) and pancreatic pseudocyst (n = 1). Controls comprised 9 patients who underwent conventional open distal pancreatectomy (Open-DP) for benign or low malignant lesions of the pancreas in the same period., Results: No significant differences were identified between HALS-DP and Open-DP in operation time. However, intra-operative blood loss, CRP on post-operative day (POD) 1 [5.5 mg/dl (1.8-8.1) vs. 9.7 mg/dl (5.9-12.1); p = .006] and POD 3 [8.5 mg/dl (1.7-11.1) vs. 17.7 mg/dl (10.7-21.5); p = .003], occurrence of post-operative SIRS (13% vs. 67%; p < .05, one-sided), duration of SIRS [0 day (0-1) vs. 1 day (0-4); p = .02] and post-operative hospital stay were significantly lower in HALS-DP than in Open-DP. Furthermore, no pancreatic fistula was seen with HALS-DP, as compared to 2 (22%) with Open-DP., Conclusion: HALS-DP is safer and less invasive than Open-DP for benign or low malignant pancreatic tumors.

We report a case of xanthogranulomatous cholecystitis (XGC) showing high levels of serum DUPAN-II in a 65-year-old woman. Preoperative radiologic examination showed no abnormal findings except in the gallbladder. Endoscopic ultrasonography was effective for differentiating chronic cholecystitis from gallbladder cancer before the operation. Cholecystectomy was performed by laparotomy, and the diagnosis of XGC was confirmed intraoperatively by examining a frozen section. Histologically, no cancer lesion was observed in the gallbladder, while immunochemical reactivity to DUPAN-II was demonstrated in the brush-border area of the epithelium and in histiocytes in the gallbladder. The half-life of serum DUPAN-II in our patient after cholecystectomy was approximately 1 month, and finally dropped to within the normal range after cholecystectomy.

A 50-year-old male with hepatitis B was referred for a small intrahepatic nodule. Magnetic resonance images raised strong suspicion of a benign lesion, such as an inflammatory pseudotumor, while the other radiological studies were equivocal. Furthermore, the high-intensity image on diffusion magnified-weighted imaging with a low B value strongly suggested a benign tumor. In spite of the absence of typical clinical or radiological findings, needle biopsy revealed an intrahepatic cholangiocarcinoma (ICC). The diagnosis of peripheral ICC rich in fibrous tissue seems to require needle biopsy for pathological examination with immunohistochemical staining because it frequently mimics other diseases, including benign tumors.

Background/purpose: We provide an initial report of the indications and procedure for three-port laparoscopic partial hepatectomy., Methods: Three-port laparoscopic partial hepatectomy was performed in nine patients (age, 49 to 73 years) at our department. Eight patients (seven men and one woman) had hepatocellular carcinoma (HCC); six of these patients had liver cirrhosis (LC) and two had chronic hepatitis (CH). The ninth patient, a woman had a single metastatic liver tumor from colon cancer. The tumors were located in regons S(2), S(3), S(4), S(5), S(6), and S(8). Preoperative liver function assessment revealed Child-Pugh classification A or B. All the tumors were located superficially, and their diameter averaged approximately 3 cm. Hepatectomy was performed laparoscopically, using an ultrasonically activated device (USAD) with or without microwave coagulation therapy (MCT)., Results: The operative time was 50 to 168 min, and the intraoperative blood loss ranged from 32 to 158 g. The postoperative hospital stay was 5 to 17 days. No recurrences, including local relapse, were observed., Conclusions: Three-port laparoscopic partial hepatectomy is safe and feasible for patients with Child-Pugh liver function classification A or B if the tumor is located superficially and is less than 3 cm in diameter.

In order to investigate mechanisms underlying the occurrence of bile duct injuries (BDIs) during laparoscopic cholecystectomy (LC), we analyzed results for 34 patients (0.59%; 17 men, 17 women; average age, 57 years) with BDI out of 5750 LCs, based on questionnaire responses from surgical operators, records of direct interviews with these operators, operative reports, and videotapes of the operations. The indications for LC in the 34 patients were chronic cholecystitis in 32 patients and acute cholecystitis in 2. The BDIs in these patients were divided into four classes using the Stewart-Way classification: class I, incision (incomplete transection) of the common bile duct (CBD), n = 6 (17.6%); class II, lateral damage to the common hepatic duct (CHD), n = 9 (26.5%); class III, transection of the CBD or CHD, n = 15 (44.1%); and class IV, right hepatic duct or right segmental hepatic duct injuries, n = 4 (11.8%). In all class III and 3 class I cases (18 in total; incidence 53%), the mistake involved misidentifying the CBD as the cystic duct. Of all types (classes) of injuries, class III injuries showed the mildest gallbladder inflammation, and there was a significant (P = 0.0005) difference in the severity of inflammation between class II and III injuries. We conclude that complete transection of the CBD, which is rare in laparotomy, was the most common BDI pattern occurring during LC and that the underlying factor in the operator making this error was mistaking the CBD for the cystic duct.
