Preoperative Neutrophil-to-Lymphocyte Ratio in Postmenopausal Breast Cancer Patients.

INTRODUCTION: Neutrophil-to-lymphocyte ratio (NLR) has been recognized as a marker of systemic inflammation with a prognostic impact in patients with various cancers, including breast cancer. The aim of this study was to investigate the relationships between the preoperative NLR and breast cancer prognosis in the patients before and after menopausal age, and its relationship with other prognostic factors. METHODS: A total of 1868 patients with clinical Stage I-III primary breast cancer were enrolled. The associations between clinicopathological factors and the preoperative NLR were analyzed, and relapse-free survival (RFS) and overall survival (OS) were estimated. RESULTS: Statistical analyses stratified by the menopausal status revealed that a high NLR was significantly associated with worse RFS (P < 0.001) and OS (P = 0.001) in postmenopausal patients, but not in premenopausal patients. Although the postmenopausal patients with relapsed cancer tended to have higher NLR levels than those without relapse (P = 0.079), NLR levels of premenopausal patients with relapsed cancer were significantly lower than that of relapse-free patients (P = 0.024). In postmenopausal patients, a high NLR was only associated with worse RFS in patients with hormone receptor-positive, human epidermal growth factor receptor 2-negative breast cancer (P < 0.001), in those managed without adjuvant chemotherapy (P = 0.003); this association was not observed in patients who received adjuvant chemotherapy. CONCLUSIONS: The preoperative NLR can be a useful prognostic marker, especially in postmenopausal breast cancer patients. The relationships between the NLR and breast cancer prognosis may be more evident when patients are assessed according to their menopausal status.

[Comparative Safety Study of Original and Generic Docetaxel without Alcohol in the Treatment of Breast Cancer].

Docetaxel(DTX)is a key drug for breast cancer treatment; however, its formulation contains alcohol, which can cause several problems. We have been preparing original DTX without using its accompanying alcohol-solubilizing solution since 2013 and switched to generic DTX without alcohol in 2015. In this study, we compared adverse events between the original and generic DTX, both of which did not contain alcohol. We retrospectively investigated the occurrence of adverse events in breast cancer patients who were treated with DTX(75 mg/m2)as neoadjuvant or adjuvant chemotherapy from January 2013 to December 2017. 201 patients participated in the study(75/126 in the original/generic groups). The incidence of febrile neutropenia, hypersensitivity reactions, and skin toxicities did not differ between the groups(p=0.620, 0.066, 0.205). The severity of edema and peripheral neuropathy was significantly worse in the patients receiving the generic DTX (p<0.01, <0.01). The findings suggest a difference in the incidence of edema and peripheral neuropathy following treatment with the original and generic DTX, regardless of the inclusion of alcohol.

Evaluation of graft stiffness using acoustic radiation force impulse imaging after living donor liver transplantation.

Acoustic radiation force impulse (ARFI) imaging is an ultrasound-based modality to evaluate tissue stiffness using short-duration acoustic pulses in the region of interest. Virtual touch tissue quantification (VTTQ), which is an implementation of ARFI, allows quantitative assessment of tissue stiffness. Twenty recipients who underwent living donor liver transplantation (LDLT) for chronic liver diseases were enrolled. Graft types included left lobes with the middle hepatic vein and caudate lobes (n = 11), right lobes (n = 7), and right posterior segments (n = 2). They underwent measurement of graft VTTQ during the early post-LDLT period. The VTTQ value level rose after LDLT, reaching a maximum level on postoperative day 4. There were no significant differences in the VTTQ values between the left and right lobe graft types. Significant correlations were observed between the postoperative maximum value of VTTQ and graft volume-to-recipient standard liver volume ratio, portal venous flow to graft volume ratio, and post-LDLT portal venous pressure. The postoperative maximum serum alanine aminotransferase level and ascites fluid production were also significantly correlated with VTTQ. ARFI may be a useful diagnostic tool for the noninvasive and quantitative evaluation of the severity of graft dysfunction after LDLT.

Association Between Preoperative Osteopenia and Prognosis in Breast Cancer Patients.

BACKGROUND/AIM: Osteopenia, the loss of bone mineral density (BMD), was recently reported as a prognostic factor in various cancers. However, the prognostic significance of preoperative osteopenia in breast cancer remains unclear. This study aimed to clarify the clinical significance of preoperative osteopenia in breast cancer. PATIENTS AND METHODS: We retrospectively analyzed the relationship between osteopenia and clinical factors and prognosis in 532 patients with pathological Stage I-III primary breast cancer between 2009 and 2017. Osteopenia was assessed by measuring the average pixel density (Hounsfield unit) in the midvertebral core of the 11th thoracic vertebra on enhanced preoperative computed tomography. RESULTS: Osteopenia was diagnosed in 186 (35.0%) patients. The recurrence-free survival (RFS) rate was significantly worse in the osteopenia group than in the non-osteopenia group (p=0.0275), but there was no significant difference in overall survival (OS) between the two groups. When evaluated by menopausal status, RFS and OS were significantly worse in the osteopenia group than in the non-osteopenia group (p=0.0094 and p=0.0264, respectively) in premenopausal patients. However, there were no significant differences in RFS and OS between the two groups among postmenopausal patients. In premenopausal patients, osteopenia was an independent prognostic factor for RFS in a multivariate analysis (p=0.0266). CONCLUSION: Preoperative osteopenia was independently associated with recurrence of breast cancer.

A dramatic response to an immune checkpoint inhibitor plus chemotherapy in a patient with metastatic metaplastic carcinoma of the breast: A case report.

We present a unique case of metastatic metaplastic breast carcinoma responding dramatically to immunochemotherapy. A 46-year-old Japanese woman with primary metaplastic carcinoma of the breast, which was immunohistochemically confirmed to be triple-negative breast cancer, underwent radical surgery, followed by adjuvant chemotherapy with an anthracycline and a taxane. Since multiple lung metastases were detected two months post-chemotherapy and the primary site was shown to be PD-L1-positive, the immune checkpoint inhibitor (ICI) pembrolizumab plus gemcitabine/carboplatin was initiated. While the treatment was discontinued after 15 days due to suspected drug-induced pneumonitis, the lung metastases significantly shrank with no development of new lesions for three months. The patient remained alive as of approximately 15 months after the recurrence date. This case highlights the potential of immunochemotherapy in treating metaplastic breast carcinomas.

A case of BIA-ALCL in which postoperative chest wall recurrence was highly suspected: the third reported case of BIA-ALCL in Japan.

BACKGROUND: Breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL) is a rare malignancy. Many cases of BIA-ALCL are identified based on the presence of late-onset effusion and/or masses. Importantly, the United States Food and Drug Administration noted that in all cases diagnosed in patients with textured implants, the patients either had a history of mixed implantation of smooth and textured devices or no clinical history was supplied for review. In Japan, the first case of BIA-ALCL was reported in 2019, and we encountered the third case in Japan in December 2021. There have been a total of five cases of BIA-ALCL previously reported at Japanese academic conferences (Japan Oncoplastic Breast Surgery Society. http://jopbs.umin.jp/medical/index.html ), of which only the first case has been published. Unlike the first case, this patient had clinical features that were highly suggestive of the postoperative chest wall recurrence of breast cancer, with a mass and rash on the skin. CASE PRESENTATION: The patient was a 45-year-old woman who had undergone breast reconstruction after breast cancer surgery of the right breast 8 years previously. The patient presented with a mass and skin rash inside the inframammary area, and we suspected a damaged silicone breast implant (SBI) or chest wall recurrence. We examined the mass by a core needle biopsy and made a pathological diagnosis of BIA-ALCL. Imaging findings suggested internal thoracic lymph node swelling and lymphoma infiltration beyond the capsule but no metastatic lesions (cStage III). After en bloc resection of the SBI and lymphoma, adjuvant systemic therapy was performed. CONCLUSION: We encountered the third case of BIA-ALCL in Japan. This was a case with clinically advanced stage of disease; however, the BIA-ALCL was found to be in remission.

Clinical usefulness of (18) F-fluorodeoxyglucose positron emission tomography/computed tomography for patients with primary liver cancer with special reference to rare histological types, hepatocellular carcinoma with sarcomatous change and combined hepatocellular and cholangiocarcinoma.

AIM: The role of (18) F-fluorodeoxyglucose positron emission tomography (FDG-PET) in the diagnosis and staging of primary liver cancer has been demonstrated in several reports. However, no preoperative evaluations of sarcomatous hepatocellular carcinoma (HCC) and combined hepatocellular and cholangiocarcinoma (cHCC-CC) with FDG-PET have been reported so far. METHODS: Fifty-three HCC patients and three cHCC-CC patients who received liver resection or living-donor liver transplantation were enrolled in this study. All 56 patients had undergone preoperative FDG-PET, and a total of 67 HCC and three cHCC-CC were analyzed histologically. The relationship between clinicopathological features and the maximum standardized uptake value (SUVmax) of tumors were evaluated. RESULTS: The detection rate of HCC by FDG-PET was 43.3 %, and the sensitivity of FDG-PET for the detection of HCC was significantly associated with tumor differentiation, tumor size and microvascular invasion. All three cHCC-CC were detected by FDG-PET. The SUVmax values of the three sarcomatous HCC (SUVmax 14.1, 18.6 and 25.0) and the three cHCC-CC (SUVmax 9.9, 12.0 and 13.0) were higher than that of the poorly differentiated HCC (mean SUVmax 5.7 ± 2.3). CONCLUSION: SUVmax may be a useful diagnostic tool for the preoperative evaluation of the aggressiveness of primary liver cancers such as sarcomatous HCC and cHCC-CC.

Granulocyte colony-stimulating-factor-producing hepatocellular carcinoma with extensive sarcomatous changes: report of a case.

This report describes a rare case of hepatocellular carcinoma (HCC) producing granulocyte colony-stimulating factor (G-CSF). A 46-year-old male with chronic hepatitis B, who presented with fever, general malaise, loss of appetite, and weight loss, had a huge liver mass in the portal region. He had marked granulocytosis and his serum level of G-CSF was elevated. Complete tumor resection was performed, and the pathological assessment of the resected specimen revealed HCC with extensive sarcomatous changes and immunohistochemical staining for G-CSF and G-CSF receptor. Only a few cases of G-CSF-producing HCC have been reported, and this is the first case of G-CSF-producing HCC that also expressed G-CSF receptor.

Recurrent hepatitis B following recurrence of hepatocellular carcinoma after living donor liver transplantation.

Hepatitis B virus (HBV) recurrence after liver transplantation for HBV-associated liver diseases results in decreased patient and graft survival. Herein we have reported two cases of HBV recurrence following relapse of hepatocellular carcinoma (HCC) after living donor liver transplantation (LDLT). Both cases had LDLT for end-stage liver disease secondary to HBV infection with nodules of HCC exceeding the Milan criteria. HBV prophylaxis using hepatitis B immunoglobulin with nucleos (t) ide analogues were given and HBV DNA levels were consistently undetectable after LDLT. HCC recurred at 5 months and 13 months posttransplant respectively, and chemotherapy and radiation therapy were performed. HBV recurrence occurred during the treatment of HCC. HBV DNA levels increased despite the treatment with anti-HBV agents after HBV recurrence. In hepatitis B surface antigen positive recipients, HBV prophylaxis should be intensified during the treatment of recurrent HCC.

Successful Prevention of Tumour Lysis Syndrome in HER2-positive Breast Cancer: Case Report and Literature Review.

BACKGROUND/AIM: Tumour lysis syndrome (TLS) is a life-threatening oncological emergency. TLS is rare and associated with a higher mortality rate in solid tumours than in haematological malignancies. Our case report and literature review aimed to identify the distinctive features and hazards of TLS in breast cancer. CASE REPORT: A 41-year-old woman complained of vomiting and epigastric pain and was diagnosed with HER2-positive, hormone-receptor-positive breast cancer with multiple liver and bone metastases and lymphangitis carcinomatosis. She had several risk factors for TLS: high tumour volume, high sensitivity to antineoplastic treatment, multiple liver metastases, high lactate dehydrogenase levels, and hyperuricaemia. To prevent TLS, she was treated with hydration and febuxostat. One day after the first course of trastuzumab and pertuzumab, she was diagnosed with disseminated intravascular coagulation (DIC). After 3 further days of observation, she was relieved of DIC and administered a reduced dose of paclitaxel without life-threatening complications. The patient achieved a partial response after four cycles of anti-HER2 therapy and chemotherapy. CONCLUSION: TLS in solid tumours is a lethal situation and can be complicated by DIC. Early recognition of patients who are at risk of TLS and initiation of therapy is essential to avoid fatal situations.

Virtual monochromatic spectral CT imaging in preoperative evaluations for intraductal spread of breast cancer: comparison with conventional CT and MRI.

PURPOSE: To investigate the efficacy of virtual monochromatic spectral computed tomography imaging (VMI) in the preoperative evaluation for intraductal spread of breast cancer. MATERIALS AND METHODS: Twenty-four women who underwent spectral CT and were pathologically diagnosed with ductal carcinoma with a ≥ 2-cm noninvasive component were retrospectively enrolled in Group 1. Twenty-two women with 22 lesions pathologically diagnosed with ductal carcinoma in situ or microinvasive carcinoma were enrolled in Group 2. We compared the contrast-to-noise ratios (CNRs) of the lesions on conventional 120-kVp CT images and 40-keV VMIs in Group 1. Two board-certified radiologists measured the maximum diameters of enhancing areas on 120-kVp CT, 40-keV VMI, and MRI in Group 2 and compared with histopathological sizes. RESULTS: The quantitative assessment of Group 1 revealed that the mean ± SD of the CNRs in the 40-keV images were significantly greater than those in the 120-kVp images (5.5 ± 1.9 vs. 3.6 ± 1.5, p < 0.0001). The quantitative assessment of Group 2 demonstrated that the lesion size observed in the conventional 120-kVp CT images by both readers was significantly underestimated as compared to the histopathological size (p = 0.017, 0.048), whereas both readers identified no significant differences between the lesion size measured on 40-keV VMI and the histopathological data. In a comparison with MRI, 40-keV VMI provided measurement within a 10-mm error range in more lesions as compared to the conventional 120-kVp CT. CONCLUSION: VMI improves the evaluation of intraductal spread and is useful for the preoperative evaluations of breast cancer.

Technical evolution of laparoscopic hepatic resection: a single institutional experience.

PURPOSE: Laparoscopic hepatic resection (LHR) is still a challenging and developing surgical modality because of technical difficulty and a lack of training opportunities and experience. In this study, we present the results of our initial experiences of LHR, focusing on technical evolution in the management of LHR. METHODS: Between April 2011 and March 2012, a total of 12 LHRs were performed. The first 5 of these LHRs were performed under laparoscopic assistance (hybrid-LHR), while the last 7 LHRs were performed totally laparoscopically (pure-LHR). Indications for LHR were hepatocellular carcinoma (n = 9) and metastatic liver cancer (n = 3). LHR procedures consisted of partial resection (n = 2), left lateral segmentectomy (n = 2), and left lobectomy (n = 1) in the hybrid-LHR group, and partial resection (n = 4), left lateral segmentectomy (n = 2), and right lobectomy (n = 1) in the pure-LHR group. Operative outcomes were compared between the groups and technical modifications were evaluated. RESULTS: The mean operative time, blood loss, and length of hospital stay in the hybrid- and pure-LHR groups were 3.8 and 6.1 hours, 220 and 611 ml, and 9.4 and 7.4 days, respectively. There were no postoperative complications in both groups. Tumor margins were negative in all cases. CONCLUSIONS: LHR is a feasible and effective procedure for patients with various types of liver tumors, although technical challenges still need to be overcome.

Impact of serum vitamin D on the response and prognosis in breast cancer patients treated with neoadjuvant chemotherapy.

BACKGROUND: Several studies have recently reported that the relationships between serum vitamin D and the prognosis or the pathological response to neoadjuvant chemotherapy (NAC) in breast cancer. However, there are no data regarding the clinical impacts of the vitamin D in Japanese breast cancer patients so far. PATIENTS AND METHODS: In the present study, a total of 250 patients with clinical Stage I-III primary breast cancer who were treated with NAC and subsequently underwent definitive surgery were included. Serum 25-hydroxvitamin D (25(OH)D) levels were evaluated using blood samples obtained before NAC. RESULTS: The serum 25(OH)D was positively associated with age, and the serum 25(OH)D was significantly higher in postmenopausal women than that in pre/peri-menopausal women. Serum 25(OH)D level was not associated with the achievement of pathological complete response (pCR) in this cohort. The low 25(OH)D levels were significantly associated with shorter time to distant recurrence (TTDR). According to the univariate analysis, high clinical stage before NAC (cStage III) and low serum 25(OH)D level were significantly associated with the shorter TTDR, and pCR was significantly associated with the longer TTDR. According to a multivariate analysis, low serum 25(OH)D level were independent poor prognostic factors for TTDR. CONCLUSIONS: The low 25(OH)D levels were significantly associated with poorer prognosis in Japanese women with operable breast cancer patients treated with NAC.

Pure laparoscopic right hepatectomy in the semi-prone position using the intrahepatic Glissonian approach and a modified hanging maneuver to minimize intraoperative bleeding.

PURPOSE: Although laparoscopic liver resection has been widely adopted, performing a pure laparoscopic right hepatectomy remains a challenging procedure. The aim of this report is to evaluate the efficiency of a pure laparoscopic right hepatectomy (PLRH) in the semi-prone position using the intrahepatic Glissonian approach and a modified hanging maneuver. METHODS: Pure laparoscopic right hepatectomy was performed in the semi-prone position with the use of an intrahepatic Glissonian approach and modified hanging maneuver for patients with primary liver cancer (n = 3) and metastatic liver cancer (n = 1). RESULTS: The intraoperative total blood loss was only 95-140 g (mean: 126.2 g). None of the patients required a blood transfusion, and no serious complications were encountered. The durations of the surgeries ranged from were 308 to 445 min (mean: 394.8 min). The postoperative hospital stay was 8-11 days (mean 9.5 days). CONCLUSION: Pure laparoscopic right hepatectomy in the semi-prone position using the intrahepatic Glissonian approach and a modified hanging maneuver is thus considered to be a safe modality, which minimizes intraoperative bleeding.

The clinical usefulness of the CTS5 in the prediction of late distant recurrence in postmenopausal women with estrogen receptor-positive early breast cancer.

BACKGROUND: Clinical Treatment Score post-5 years (CTS5) is a promising prognostic tool to evaluate late distant recurrence (DR) risk for breast cancer after 5-year adjuvant endocrine therapy. PATIENTS AND METHODS: Among 560 postmenopausal women with pathological stage I-III estrogen receptor-positive (ER+) primary breast cancer, 383 women who had received 5-year adjuvant endocrine therapy without any recurrence at 5 years after surgery were included in this study. The CTS5 was calculated for each patient using a previously published formula, and the patients were stratified by their CTS5 values into the low-, intermediate- and high-CTS5 risk groups. RESULTS: According to the CTS5, 205 (53.5%), 106 (27.7%) and 72 (18.8%) patients were classified into the low-, intermediate-, and high-CTS5 risk groups, respectively. A higher ER expression level was significantly associated with the low CTS5. The increased administration of adjuvant chemotherapy was significantly associated with a high CTS5. The occurrence of DR was higher in the intermediate and high CTS5 groups than in the low CTS5 group. The DRFS in the low CTS5 risk group was significantly better than that in the intermediate- or high-risk groups. In the ER-high or HER2-negative (HER2-) group, the DRFS in the low-risk group was significantly better than that of the intermediate- or high-risk groups. However, in the low-ER or HER2-positive group, there was no significant difference in DRFS among the three risk groups. CONCLUSIONS: In postmenopausal women with ER+ breast cancer, low CTS5 was considered to be associated with a very low risk of late DR. Thus, extended endocrine therapy may be unnecessary for patients with low CTS5 scores. Extended endocrine therapy should be offered for patients with intermediate or high CTS5 scores, especially those with high-ER and HER2- breast cancer.

Tumor-infiltrating lymphocytes and hepatocellular carcinoma: pathology and clinical management.

The presence of tumor-infiltrating lymphocytes (TILs) in hepatocellular carcinoma (HCC) is relatively rare. The prognosis of patients with HCC and marked TILs is better than that of patients with HCC without TILs. TILs in HCC tissues are mainly T cells, and previous reports suggested that TILs might be important antitumor effector cells. TILs have been extensively analyzed, and subpopulations of CD3(+), CD4(+), and CD8(+) T cells are often present in HCC. Some studies have reported that the percentage of CD8(+) T cells, which might have cytotoxic activity, is decreased in tumors with TILs, as compared with noncancerous tissues. Although the antitumor effects of TILs seem to be impaired in HCCs, the underlying mechanism has remained unclear until quite recently. Pathological and in vitro studies have now shown that regulatory T cells play important roles in the deterioration of the antitumor effects of TILs. The aim of this review is to introduce recent pathological findings for TILs in HCC and to evaluate new therapeutic strategies in this field.

Efficacy of Adjuvant Combination Therapy With Trastuzumab and Chemotherapy in HER2-positive Early Breast Cancer: A Single Institutional Cohort Study from Clinical Practice.

BACKGROUND/AIM: To evaluate the improvement in the prognosis by adjuvant trastuzumab in clinical practice and the risk factors for distant recurrence, we retrospectively investigated the prognosis of HER2-positive early breast cancer in our department before and after the introduction of adjuvant trastuzumab. PATIENTS AND METHODS: Cohorts A and B included 161 and 182 cases, respectively, who underwent surgery before (2000-2007) and after (2008-2015) the introduction of adjuvant trastuzumab. RESULTS: The rates of relapse-free and distant metastasis-free survival were significantly better in cohort B than in cohort A. The risk factors of distant recurrence found in cohort A, such as the presence of lymph node metastasis, lymphatic invasion, and a low histological grade, did not increase the risk in cohort B. CONCLUSION: Many risk factors seemed to have been negated by adjuvant trastuzumab administration. Therefore, further escalation of adjuvant treatment should be carefully considered.

The comparison of the anatomic stage and pathological prognostic stage according to the AJCC 8th edition for the prognosis in Japanese breast cancer patients: data from a single institution.

BACKGROUND: The TNM system, which reflects the anatomical extent of disease, was used for stage definition. In the recently published AJCC 8th edition, the new staging system of the clinical and pathological prognostic stage, which incorporates biological factors, is introduced. PATIENTS AND METHODS: A total of 2622 patients with primary breast cancer at stage I-III were included in this study. The anatomic stage (aStage) and the pathological prognostic stage (ppStage) for each case were determined according to the definition of the AJCC 8th edition, and the influence of these stages on the prognosis was compared. RESULTS: The stage distributions of aStage and ppStage were as follows: aStage, stage IA (54.8%), IB (1.1%), IIA (26.1%), IIB (9.2%), IIIA (5.6%), IIIB (0.1%), and IIIC (3.1%); and ppStage, stage IA (66.6%), IB (13.1%), IIA (11.1%), IIB (3.2%), IIIA (3.3%), IIIB (1.4%), and IIIC (1.2%). Compared with the aStage, the ppStage stayed the same in 1710 patients (65.2%), was downstaged in 778 patients (29.7%), and was upstaged in 134 patients. The pathological tumor size (pT2) and lymph node metastasis (pN1) were associated with downstaging, and histological grade 3 was associated with upstaging. ER positivity, PgR positivity, and HER2-positivity were significantly associated with downstaging, and the TN subtype was associated with upstaging. Both the aStage and ppStage were significantly associated with the prognosis; however, the Kaplan-Meier curves for the relapse-free survival (RFS), distant recurrence-free survival (DRFS), and overall survival were better stratified by the ppStage. CONCLUSION: The ppStage reflects the prognosis of patients with early breast cancer more accurately than the aStage.

Coexistence of mucinous cystic neoplasm occurring in the head of the pancreas with annular pancreas: report of a case.

Mucinous cystic neoplasms (MCN) of the pancreas are rare tumors that are almost exclusively located in the body or the tail of the pancreas. A 60-year-old woman with no history of pancreatic disease was referred to our hospital with a chief complaint of dull pain in the upper abdomen. Abdominal computed tomography showed a multilocular cystic mass of 7.0 cm in the head of the pancreas, and endoscopic retrograde cholangiopancreatography showed no communication between the cystic mass and the main pancreatic duct. A pancreatoduodenectomy was performed for the complete resection of the tumor, and an annular pancreas was discovered by accident. The pathological examination of the tumor led to a definitive diagnosis of MCN with ovarian-type stroma. To our knowledge this is the first documented case of MCN occurring in the head of the pancreas and associated with annular pancreas.

Pancreatogastrostomy with an elastic purse-string suture around the gastric orifice after pancreatoduodenectomy.

Postoperative pancreatic fistula (POPF) is a potentially fatal complication of pancreatoduodenectomy (PD). Fixation of the remnant pancreas to the gastric wall is considered essential to prevent anastomotic leakage in patients undergoing pancreatogastrostomy (PG) after PD. PG was performed with invagination of the pancreatic stump. To limit the number of sutures in the pancreas parenchyma to three or four, we placed an elastic purse string suture around the orifice of the posterior gastric wall in an attempt to fix the gastric wall to the remnant pancreas. We performed PG using this technique in 30 patients. According to the international POPF criteria, POPF developed in three (10%) patients; as grade A in one, and grade B in two. These results demonstrate the potential advantage of performing PG after PD, by using this invaginated technique with an elastic suture.
