ABSTRACT
BACKGROUND/AIM: The hemoglobin, albumin, lymphocyte, and platelet (HALP) score is an immune-nutritional assessment score that is a prognostic indicator for several malignant tumors. This study aimed to investigate its prognostic value in patients who underwent hepatectomy for hepatocellular carcinoma. PATIENTS AND METHODS: Data of 685 patients with hepatocellular carcinoma who underwent hepatectomy at Kurume University between 2006 and 2021 were retrospectively analyzed. The patients were classified into high and low HALP score groups based on a cut-off HALP score determined using a receiver operating characteristic curve. To minimize bias, 1:1 propensity score matching was performed. Kaplan-Meier curves were used to estimate survival time, and data were evaluated using the log-rank test. Univariate and multivariate analyses were performed using Cox hazard or logistic regression models for assessing survival time and postoperative outcomes, respectively. RESULTS: Low HALP scores were significantly associated with poor overall survival (p=0.0066). Univariate and multivariate analyses revealed that the HALP score independently predicted overall survival (p=0.005). However, the HALP score was not significantly related to recurrence-free survival or postoperative outcomes. CONCLUSION: The HALP score is a simple inexpensive tool for predicting prognosis after hepatectomy for hepatocellular carcinoma.

BACKGROUND/AIM: The outcome of hepatectomy for a hepatocellular carcinoma (HCC) exceeding 10 cm (i.e., huge HCC) remains unfavorable. The aim of the current study was to evaluate the optimal therapeutic approach for huge HCCs. PATIENTS AND METHODS: Between 2008 and 2018, patients with a huge HCC who underwent treatment at our institution were enrolled. Cases not meeting the criteria (Child-Pugh grade A or performance status 0/1) and patients with distant metastases were excluded. Patients were stratified into three groups: a) upfront hepatectomy (Upfront); b) hepatectomy subsequent to hepatic arterial infusion chemotherapy (HAIC-Hr); and c) HAIC alone (HAIC). Survival rates, including overall survival (OS) and progression-free survival (PFS), were analyzed. The cancer-specific mortality attributed to recurrence within one year after surgery was defined as "futile surgery"; the rate of futile surgery was also assessed. RESULTS: A total of 70 cases were censored (Upfront/HAIC-Hr/HAIC: 28/13/29). The 5-year PFS and OS rates for Upfront, HAIC-Hr, and HAIC were 7.7%, 69.2%, and 6.9%, and 37.1%, 79.1%, and 19.7%, respectively. The number of futile surgeries was 6 (21.4%) in the Upfront group, whereas no such cases occurred in the HAIC-Hr group. CONCLUSION: Although hepatectomy was advocated in the Upfront group due to the potential resectability, the outcomes were comparable to those of the HAIC group. Conversely, the HAIC-Hr group had promising outcomes, marked by a decreased prevalence of futile surgeries. Huge HCCs should be regarded as borderline resectable, even when deemed potentially resectable. Therefore, a multidisciplinary therapeutic approach might be reasonable.

BACKGROUND/AIM: This study aimed to characterize intraductal papillary neoplasm of the bile duct (IPNB) in patients undergoing initial and recurrent surgical resection and to evaluate the appropriateness of surgical treatment strategies. PATIENTS AND METHODS: This study included 14 patients who underwent liver resection for intrahepatic IPNB. We assessed intraoperative and postoperative clinicopathological factors in patients undergoing both initial and recurrent surgeries. RESULTS: Four patients experienced recurrence after initial surgery; all underwent pancreaticoduodenectomy. Postoperative complications were classified as Clavien-Dindo Grade 1-2 in three patients and Grade IIIb in one patient. There were no in-hospital deaths. CONCLUSION: Pancreaticoduodenectomy for recurrent cases following hepatectomy for IPNB is considered safe within an acceptable range and contributes to a favorable long-term prognosis.

BACKGROUND/AIM: Laparoscopic anatomical liver resection (LAR) for hepatocellular carcinoma (HCC) is technically demanding. Therefore, this study aimed to compare the perioperative and long-term oncological outcomes of LAR and open anatomical liver resection (OAR) for HCC. PATIENTS AND METHODS: We retrospectively analyzed 460 consecutive patients who underwent anatomical liver resection as the initial treatment for primary HCC between January 2010 and February 2024. Patients were categorized into the LAR and OAR groups, and surgical outcomes between the groups were compared using 1:1 propensity score matching (PSM). RESULTS: After PSM, the LAR and OAR groups included 100 patients each. The LAR group exhibited significantly less blood loss (80 vs. 436 ml; p<0.0001), lower transfusion rates (0% vs. 12%; p=0.0002), shorter operative time (345 vs. 398 min; p=0.0009), lower postoperative morbidity rates (6% vs. 34%; p<0.0001), and shorter postoperative hospital stay (8 vs. 15 days; p<0.0001) than the OAR group. The 1-, 3-, and 5-year overall survival rates were 97.7%, 96.2%, and 89.7%, respectively, in the LAR group and 98.0%, 92.7%, and 88.4%, respectively, in the OAR group (p=0.5874). The 1-, 3-, and 5-year recurrence-free survival rates were 93.2%, 75.7%, and 60.7%, respectively, in the LAR group and 86.0%, 64.5%, and 59.1%, respectively, in the OAR group (p=0.2314). CONCLUSION: LAR showed improvements in perioperative complications, reduced postoperative hospital stay, and comparable recurrence-free and overall survival rates with those of OAR. Therefore, LAR for HCC is considered safe, feasible, and oncologically acceptable in selected patients.

BACKGROUND: It is unclear whether hepatectomy, which ranges in invasiveness from partial to major hepatectomy, is safe and feasible for older adult patients. Therefore, we compared its postoperative complications and long-term outcomes between younger and older adult patients. METHODS: Patients who underwent hepatectomies for hepatocellular carcinoma (N = 883) were evaluated. Patients were divided into two groups: aged < 75 years (N = 593) and ≥ 75 years (N = 290). Short-term outcomes and prognoses were compared between the groups in the entire cohort. The same analyses were performed for the major hepatectomy cohort. RESULTS: In the entire cohort, no significant differences were found in complications between patients aged < 75 and ≥ 75 years, and the multivariate analysis did not reveal age as a prognostic factor for postoperative complications. However, overall survival was significantly worse in older patients, although no significant differences were noted in time to recurrence or cancer-specific survival. In the multivariate analyses of time to recurrence, overall survival, and cancer-specific survival, although older age was an independent poor prognostic factor for overall survival, it was not a prognostic factor for time to recurrence and cancer-specific survival. In the major hepatectomy subgroup, short- and long-term outcomes, including time to recurrence, overall survival, and cancer-specific survival, did not differ significantly between the age groups. In the multivariate analysis, age was not a significant prognostic factor for complications, time to recurrence, overall survival, or cancer-specific survival. CONCLUSION: Hepatectomy, including minor and major hepatectomy, may be safe and oncologically feasible options for selected older adult patients with hepatocellular carcinoma.

BACKGROUND: The Japanese guideline for therapeutic strategy in HCC does not recognize any benefit of preoperative chemotherapy for potentially resectable hepatocellular carcinoma (HCC), and only upfront resec tion is recommended even for an advanced HCC. Data on preoperative chemotherapy for advanced HCC is still limited. Poor prognostic factors of HCC after resection are tumor more than 5 cm in diameter, multiple lesions, and gross tumor thrombosis, which constitute UICC7 Stage IIIA and IIIB HCC. There are no prospective studies about preoperative chemotherapy in these patients. AIM: To evaluate the benefit of preoperative chemotherapy for UICC7 Stage IIIA and IIIB potentially resectable HCC. DISCUSSION: Our recent study demonstrated that the 5-year overall survival rate (OS) of patients diagnosed as UICC7 Stage IIIA and IIIB who had received upfront resection was only 16.5%. In contrast, the 5-year OS of UICC7 Stage IIIA and IIIB initially unresectable patients who had achieved conversion from unresectable to resect able status under successful hepatic infusion chemotherapy prior to resection was as high as 61.3%. Additionally, recent studies reported transarterial chemoembolization achieved outcomes comparable with those of resection. Therefore, we believe that patients with UICC7 Stage IIIA and IIIB should be considered borderline resectable. To evaluate this hypothesis we registered the present phase II clinical trial to assess the benefit of preoperative chemo therapy followed by hepatectomy in potentially resectable UICC7 Stage IIIA and IIIB HCC patients.

BACKGROUND/AIM: The aim of this study was to evaluate hepatectomy cases that underwent preoperative chemotherapy to examine the relationship between the development of desmoplastic histopathological growth pattern (dHGP) and prognosis and recurrence and determine whether it is useful for evaluating preoperative chemotherapy. PATIENTS AND METHODS: A total of 133 cases with hepatic metastasis for colorectal cancer that underwent surgical resection. RESULTS: Of the 102 cases that underwent preoperative chemotherapy, 34 (33%) were determined to be dHGP positive, which was statistically significantly higher than the 2 of 31 cases (6.5%) that had not undergone preoperative chemotherapy. Regarding the 5-year recurrence-free survival, the dHGP group had a value of 50.3%, whereas the non-dHGP group had a value of 7.1%. For the 5-year overall survival, the dHGP group had a better prognosis than the non-dHGP group (57.6% vs. 37.1%, respectively), with a statistically significant difference. Univariate analysis of recurrence-free survival showed that the number of tumours, the Response Evaluation Criteria in Solid Tumors, and the presence or absence of dHGP were prognostic factors, whereas multivariate analysis showed that the presence or absence of dHGP was an independent prognostic factor. Univariate analysis of the overall survival showed that the number of tumours, the Response Evaluation Criteria in Solid Tumors, and presence or absence of dHGP were prognostic factors. Multivariate analysis showed that the presence or absence of dHGP was an independent prognostic factor. CONCLUSION: dHGP is useful as a new evaluation method for evaluating the efficacy of preoperative chemotherapy.

BACKGROUND: Among congenital anomalies of the portal venous system, prepancreatic postduodenal portal vein (PPPV) is very rare and has only been reported to date. Herein, we report a case of PPPV identified in preoperative examinations for hepatocellular carcinoma and a literature review. CASE PRESENTATION: A 63-year-old man was admitted to our hospital for treatment of a liver tumor. After examination, he was diagnosed with hepatocellular carcinoma with a diameter of 40 mm in segment 8. Contrast-enhanced computed tomography scan showed a portal vein passing between the duodenum and pancreas, hence called PPPV. At the hepatic hilus, the portal vein branched off in a complicated course with some porto-portal communications. We determined that anatomical resection with manipulation of the hepatic hilum in this case resulted in major vascular injury. Therefore, we performed partial liver resection, and the patient was discharged uneventfully on postoperative day 14. CONCLUSIONS: Although PPPV is an extremely rare congenital vascular variant, it is important to carefully identify vascular patterns preoperatively and to recognize the possibility of such an anomaly to avoid misidentification and inadvertent injuries during surgery.
ABSTRACT
BACKGROUND: Several studies have reported that interferon (IFN) therapy improves the prognosis of patients with hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC), especially for patients who have achieved a sustained virological response (SVR). We retrospectively evaluated the clinicopathological outcomes of patients who acquired an SVR through IFN therapy pre- or post-hepatectomy for treatment naïve HCC. METHOD: Among the 305 HCV-related HCC patients entered in this study, 59 patients (SVR group) achieved an SVR after IFN therapy and received hepatectomy either after or before achieving an SVR (n=36 and n=23, respectively), while the remaining 179 patients (control group) did not receive IFN therapy, or did not achieve an SVR through IFN therapy (n=67). RESULTS: In the SVR group, the overall survival (OS) and disease-free survival (DFS) rates were significantly higher than in the control group. We evaluated the prognosis of patients with an SVR achieved pre- or post-hepatectomy separately. There were no significant differences in OS and DFS. CONCLUSION: This result suggests that the prognosis of naïve HCC may be improved by additional INF therapy to achieve SVR status after hepatectomy.

A 67-year-old male was referred to our hospital in a state of shock. Transcatheter arterial embolization(TAE)was performed for the diagnosis of liver tumor rupture, followed by extended posterior area resection 18 days later. Histopathologically, he was diagnosed with hepatic angiosarcoma. The patient was discharged 18 days after the surgery, but readmitted on the 51st day due to bleeding shock caused by the rupture of a recurrent tumor in the liver. Although TAE was performed, the patient developed hepatic failure and died on postoperative day 81. Autopsy revealed multiple intrahepatic recurrence and peritoneal dissemination. Herein, we report a case of ruptured hepatic angiosarcoma that underwent hepatic resection after TAE and had a rapid outcome due to early postoperative rupture of recurrent lesion.

BACKGROUND/AIM: Surgical resection is the standard treatment for bile duct cancer. However, even when surgical resection is possible, the 5-year survival rate is reportedly 25.0-55.0%. Therefore, bile duct cancer is associated with poor prognoses. We conducted a clinicopathological investigation, focusing on the histological phenomenon of tumour budding, which has previously been reported to be correlated with the survival of patients with a variety of cancers. PATIENTS AND METHODS: To investigate the significance of tumour budding in distal bile duct cancer, we recruited 65 patients who underwent pancreatoduodenectomy at our institution between 1995 and 2011. Tumour budding was observed and evaluated using the 'hot spot method'. The 'low' budding group comprised 0-4 cell clusters and the 'high' budding group ≥5 cell clusters. Additionally, immunostaining was performed in high-budding areas. RESULTS: Tumour budding and stage were confirmed using a Cox proportional hazards model as independent prognostic factors for overall survival (p<0.05) in all patients. There was a significant association between budding and zinc finger E-box binding homeobox 1 expression, an endothelial-mesenchymal transition-induced transcription factor. In stage II cases, the prognosis was significantly worse in the 'high' budding group compared to that in the 'low' budding group. CONCLUSION: The budding phenomenon is an independent prognostic factor for patients with distal bile duct cancer. Understanding the mechanisms underlying tumour budding in distal bile duct cancer and its relationship with poor prognoses may be useful for the development of novel treatments for this disease.

BACKGROUND/AIM: Right hepatectomy and extended right hepatectomy (Rt-Hr) are identified as risk factors for the development of post-hepatectomy liver failure (PHLF). Although portal vein embolization (PVE) has made it possible to safely perform extended hepatectomy, to ensure safety, in our department, PVE is performed prior to Rt-Hr for hepatocellular carcinoma (HCC) regardless of the resection rate. This study aimed to retrospectively investigate the clinical course of PVE prior to Rt-Hr for HCC cases resected in our department and the appropriateness of our policy by clarifying complications and deaths. PATIENTS AND METHODS: The target period was from 2005 to 2020. Among the HCC cases resected at our hospital, those in which PVE was performed prior to Rt-Hr were included in this study. For PHLF, the definition of the International Study Group of Liver Surgery was used. The Clavien-Dindo classification was used for postoperative complications. Perioperative mortality was defined as the overall mortality within 30 days following surgery and surgery-related deaths within 90 days following surgery. RESULTS: A total of 79 cases were included. Rt-Hr was possible in all cases after PVE and there were no cases in which serious complications occurred after PVE. PHLF was found in 14 cases (17.7%)/5 cases (6.4%)/0 cases (0%) of Grade A/B/C, respectively. Regarding postoperative complications, there were no Grade IV, and Grade IIIa/IIIb were found in 13 cases (16.5%). There were no perioperative deaths. CONCLUSION: Our department's policy of performing PVE prior to all Rt-Hr was considered to be a safe and reasonable treatment strategy.

ABSTRACT: Percutaneous drainage catheters (PDCs) are required for the management of benign biliary strictures refractory to first-line endoscopic treatment. While biliary patency after PDC placement exceeds 75%, long-term catheterization is occasionally necessary. In this article, we assess the outcomes of patients at our institution who required long-term PDC placement.A single-institution retrospective analysis was performed on patients who required a PDC for 10âyears or longer for the management of a benign biliary stricture. The primary outcome was uncomplicated drain management without infection or complication. Drain replacement was performed every 4 to 12âweeks as an outpatient procedure.Nine patients (three males and six females; age range of 48-96âyears) required a long-term PDC; eight patients required the long-term PDC for an anastomotic stricture and one for iatrogenic bile duct stenosis. A long-term PDC was required for residual stenosis or patient refusal. Drain placement ranged from 157 to 408âmonths. In seven patients, intrahepatic stones developed, while in one patient each, intrahepatic cholangiocarcinoma or hepatocellular carcinoma occurred.Long-term PDC has a high rate of complications; therefore, to avoid the need for using long-term placement, careful observation or early surgical interventions are required.

A 76-year-old female was referred to our hospital with a tumor of the gallbladder using ultrasonography. CT and MRI of the abdomen and endoscopic ultrasonography revealed thickened walls of the body of her gallbladder. Endoscopic retrograde cholangiopancreatography was performed, adenocarcinoma was suspected based on bile cytology, and extended cholecystectomy with lymphadenectomy was performed. The postoperative pathological diagnosis was small cell neuroendcrine carcinoma. Three months after the surgery, CT revealed that she had multiple recurrences in the distant lymph node, and she died two months later. Gallbladder neuroendocrine carcinoma is rare and which is thought to have a poor prognosis, so effective multidisciplinary treatment must be required for this disease. In this case, it might need not to hesitate to perform preoperative endoscopic ultrasound guided fine needle aspiration(EUS-FNA).

BACKGROUND: Cholangiocarcinoma is frequently observed in patients with congenital bile duct dilatation (CBDD). Most cholangiocarcinomas are adenocarcinomas. Other types, especially neuroendocrine carcinomas (NECs), are rare. To the best of our knowledge, this is the third reported case of an NEC of the common bile duct associated with CBDD and the first to receive adjuvant chemotherapy for advanced disease. CASE PRESENTATION: A 29-year-old woman presented with upper abdominal pain. Preoperative imaging indicated marked dilatation of the common bile duct and a tumor in the middle portion of the common bile duct. She was suspected of having distal cholangiocarcinoma associated with CBDD and underwent pylorus-preserving pancreaticoduodenectomy. Pathological and immunohistological findings led to a final diagnosis of large-cell NEC (pT3aN1M0 pStageIIB). The postoperative course was uneventful, and she was administered cisplatin and irinotecan every 4 weeks (four cycles) as adjuvant chemotherapy. She has remained recurrence-free for 16 months. CONCLUSIONS: NEC might be a differential diagnosis in cases of cholangial tumor associated with congenital bile duct dilatation. This presentation is rare and valuable, and to establish better treatment for NEC, further reports are necessary.

PURPOSE: Clinically relevant postoperative pancreatic fistulas (CR-POPF) occurring after distal pancreatectomy often cause intra-abdominal infections. We monitored the presence of bacterial contamination in the ascitic fluid after distal pancreatectomy to clarify the bacterial origin of intra-abdominal infections associated with CR-POPF. METHODS: In 176 patients who underwent distal pancreatectomy, ascitic fluid bacterial cultures were performed on postoperative days (POD) 1-4 and when the drainage fluid became turbid. The association between postoperative ascitic bacterial contamination and CR-POPF incidence was investigated. RESULTS: CR-POPF occurred in 18 cases (10.2%). Among the patients with CR-POPF, bacterial contamination was detected in 0% on POD 1, in 38.9% on POD 4, and in 72.2% on the day (median, day 9.5) when the drainage fluid became turbid. A univariate analysis revealed a significant difference in ascitic bacterial contamination on POD 4 (p < 0.001) and amylase level on POD 3-4 (p < 0.001). A multivariate analysis revealed the amylase level and ascitic bacterial contamination on POD 4 to be independent risk factors. CONCLUSIONS: In the CR-POPF group, ascitic bacterial contamination was not observed in the early postoperative stage, but the bacterial contamination rate increased after pancreatic juice leakage occurred. Therefore, CR-POPF-related infections in distal pancreatectomy may be caused by a retrograde infection of pancreatic juice.

BACKGROUND: Intrahepatic cholangiocarcinoma (ICC) is primary cancer of the liver with poor prognosis because of its high potential for recurrence and metastasis. We experienced a rare case of ICC with hematogenous metastasis to the falciform ligament. We aimed to clarify the route of metastasis to the mesentery by increasing the accuracy of preoperative imaging and establish a hepatectomy to control cancer. CASE PRESENTATION: An 85-year-old woman was referred to our hospital for a detailed study of progressively increasing liver tumors. She had no subjective symptoms. Her medical history showed hypertension, aneurysm clipping for cerebral hemorrhage, and gallstones. A detailed physical examination and laboratory data evaluation included tumor markers but did not demonstrate any abnormalities. On computed tomography scan, contrast-enhanced ultrasound, and magnetic resonance imaging with gadolinium ethoxybenzyl diethylenetriamine penta-acetic acid, the tumor appeared to be located in liver segment IV, protruding outside the liver. It appeared to contain two distinct components; we suspected ICC in the intrahepatic tumor component. Laparoscopic observation revealed that the extrahepatic lesion was an intra-falciform ligament mass; laparoscopic left hepatectomy was performed. Microscopically, the main tumor in segment IV was 15 mm in diameter and was diagnosed as moderately and poorly differentiated ICC. The tumor of the intra-falciform ligament was not continuous with the main intrahepatic nodule and was also diagnosed as ICC with extensive necrosis. There were no infiltrates in the round ligament of the liver, and several tumor thrombi were found in the small veins of the falciform ligament. CONCLUSIONS: To date, there have been a few reports of metastases of primary liver cancer to the falciform ligament. At the time of preoperative imaging and pathological diagnosis, this case was suggestive of considering that the malignant liver tumor might be suspected of metastasizing to the falciform ligament. Our case improves awareness of this pathology, which can be useful in the future when encountered by hepatic specialists and surgeons.

A 71-year-old man who underwent laparoscopic partial liver resection for local recurrence hepatocellular carcinoma (HCC)in segment 4 one year after percutaneous radiofrequency ablation(RFA)for HCC. About 3 years after treatment, the patient showed elevation of serum level of tumor marker and a mass lesion in the round ligament on CT and EOB-MRI. We made a diagnosis of peritoneal dissemination of HCC. Laparoscopic extirpation of peritoneal dissemination using indocyanine green(ICG)imaging was performed and no other tumors were observed in the peritoneal cavity. A lesion was diagnosed as peritoneal dissemination of HCC, and postoperative course was uneventful. This patient underwent repeated RFA and partial resection for recurrence of HCC. The patient was died for intrahepatic multiple recurrence of HCC without peritoneal dissemination 25 months after extirpation of peritoneal dissemination. In the field of hepatobiliary surgery, ICG imaging can be used for the intraoperative real-time visualization of hepatic malignancies. The ICG imaging is restricted to detection of fluorescence for liver tumors 5-10 mm from the liver surface. In the detection of peritoneal dissemination, however, there are no such limitations. Laparoscopic extirpation using ICG imaging is useful for the detection of peritoneal dissemination of HCC and may improve the prognosis in selected patients.

BACKGROUND: There is no standard surgical method for treating pancreatic head tumors with fat replacement of the pancreatic body and tail. Total pancreatectomy procedures are usually performed to excise pancreatic head tumors and lead to endocrine function loss and subsequent development of diabetes. We present a rare case where the adipose tissue was preserved during pancreaticoduodenectomy in a patient with a solid pseudopapillary neoplasm and fat-replaced pancreatic body and tail. CASE PRESENTATION: Contrast-enhanced computed tomography scans of a 43-year-old man revealed a tumor measuring approximately 3 cm in size with calcification in the pancreatic head. Magnetic resonance cholangiopancreatography showed that the pancreatic ducts in the body and tail were completely disrupted. Furthermore, endoscopic ultrasonography showed no pancreatic parenchyma in the body and tail of the pancreas, with disruption in the main pancreatic duct. Endoscopic ultrasonography-guided fine-needle aspiration led to the final pathological diagnosis of a solid pseudopapillary neoplasm, and laparoscopic total pancreatectomy was performed. However, intraoperative findings indicated that the tumor was located in the pancreatic head. Pancreatic parenchyma was not observed in the pancreatic body or tail, as it had been completely replaced with adipose tissue. Nevertheless, the shape of the pancreas was identifiable. Therefore, pancreaticoduodenectomy was performed to transect parenchyma at the pancreatic neck, while preserving the adipose tissue present in the pancreatic body. The main pancreatic duct could not be identified at the cut surface. Therefore, we performed modified Blumgart-style pancreaticojejunostomy to cover the cut end instead of reconstructing the pancreatic duct. The patient was discharged on postoperative day 12 without complications and is being followed-up as an outpatient. His fasting blood sugar and hemoglobin A1c levels according to the National Glycohemoglobin Standardization Program reports were within normal limits, indicating that the endocrine function (insulin secretion ability) was preserved during the 1.5 years following surgery. CONCLUSIONS: In patients with pancreatic head tumors, pancreaticoduodenectomy that preserves fat-replaced pancreatic body and tail tissues can preserve postoperative endocrine function.

BACKGROUND: Few reports describe the relationship between preoperative cholangitis and surgical site infections (SSIs) after pancreaticoduodenectomy (PD). We aimed to determine the association between the incidence of preoperative cholangitis and surgical site infection following PD. METHODS: The surgical outcomes of 359 patients who underwent PD were compared between patients with (n = 92) and without (n = 267) preoperative cholangitis. Bacterial cultures from the postoperative drainage fluid were examined. Risk factors for postoperative infectious complication were evaluated. RESULTS: The incidence of postoperative infectious complications including grade B/C postoperative pancreatic fistula was high among patients with preoperative cholangitis (P < .01). The positive rate of bacterial culture in the drainage fluid until postoperative day 3 (P < .01) and the detection rate of Enterococcus species (P < .01) were higher in the preoperative cholangitis group. The most common cause of preoperative cholangitis was drainage device dysfunction mainly with plastic stent occlusion. In the multivariate analysis, preoperative cholangitis (odds ratio 2.04, 95% confidence interval 1.13 to 3.69; P = .02) was an independent risk factor for postoperative infectious complications. CONCLUSIONS: Preoperative cholangitis significantly increased ascitic bacterial contamination and the incidence of postoperative infectious complications. after PD. Appropriate preoperative biliary drainage for the prevention of preoperative cholangitis is important for improving outcomes after PD.
