Advantage of Postoperative Inflammatory Status after Laparoscopic Distal Pancreatectomy.

Introduction: Laparoscopic distal pancreatectomy (LDP) is a safe and effective procedure; however, its impact on perioperative inflammatory reactions compared with open distal pancreatectomy (ODP) remains unclear. This study aimed to assess short-term outcomes following LDP and ODP regarding inflammatory reactions.

Methods: This retrospective study of 77 consecutive patients who underwent distal pancreatectomy for low-grade malignancies between 2005 and 2022 compared white blood cell (WBC) count, C-reactive protein (CRP) level, serum albumin level, and CRP/albumin ratio (CAR) between LDP and ODP.

Trends in the treatment of advanced pancreatic cancer.

Pancreatic cancer (PC) has the poorest prognosis among digestive cancers; only 15-20% of cases are resectable at diagnosis. This review explores multidisciplinary treatments for advanced PC, emphasizing resectability classification and treatment strategies. For locally advanced unresectable PC, systemic chemotherapy using modified FOLFIRINOX and gemcitabine with albumin-bound paclitaxel is standard, while the role of chemoradiation is debated.

Rescue of outflow block of the remnant left liver after extended right hemihepatectomy for resection of a tumor in the caudate lobe.

Outflow block of the liver is a life-threatening event after living donor liver transplantation. Herein, we rescued a patient suffering from the outflow block of the remnant left hemiliver caused by bending of the left hepatic vein (LHV) after right hemihepatectomy plus caudate lobectomy combined with resection of the middle hepatic vein (MHV). A metastatic tumor sized 6 cm in the caudate lobe of the liver involving the root of the MHV was found in a 50's year old patient after resection of a right breast cancer eight years ago.

Trends in the surgical treatment for pancreatic cancer in the last 30 years.

Pancreatic cancer has the poorest prognosis among digestive cancers. During the 1990s, the 5-year survival rate of surgical patients with pancreatic cancer was 14% in Japan. However, survival rates have increased to 40% in the 2020s due to the refinement of surgical procedures and the introduction of perioperative chemotherapy.

Predictive factors for subsequent intrahepatic cholangiocarcinoma associated with hepatolithiasis: Japanese National Cohort Study for 18 years.

Background: Predictive factors for intrahepatic cholangiocarcinoma in long-term follow-up of hepatolithiasis are unknown. We thus conducted a cohort study to investigate the predictive factors for developing intrahepatic cholangiocarcinoma in hepatolithiasis.

Methods: This cohort is comprised of 401 patients registered in a nationwide survey of hepatolithiasis for 18 years of follow-up.

Rescue Partial ALPPS for Left Hemihepatectomy with Reconstruction of the Middle Hepatic Vein.

Major hepatectomy in patients with insufficient future liver remnant (FLR) volume and impaired liver functional reserve has considerable risks for posthepatectomy liver failure (PHLF). The patient was a male in his 70s with an intrahepatic cholangiocarcinoma in left hemiliver, involving the middle hepatic vein (MHV). Although FLR volume after left hemihepatectomy was estimated to be 64.

Primary hepatic neuroendocrine carcinoma diagnosed by needle biopsy: a case report.

Background: Primary hepatic neuroendocrine carcinomas (NECs) are extremely rare. The rate of recurrence after resection is extremely high, and the prognosis is poor. It is debatable whether chemotherapy or surgical resection is the optimal initial treatment for primary hepatic NECs.

Parenchymal-sparing approaches for resection of tumors located in the paracaval portion of the caudate lobe of the liver-utility of limited resection and central hepatectomy.

Purpose: Resection of liver cancer involving the paracaval portion (PC) of the caudate lobe is challenging because the PC is located deepest in the liver. This study aimed to elucidate the utility of two parenchymal-sparing approaches of limited resection and central hepatectomy for resecting tumors located in the PC.

Methods: In 2018 and 2020, 12 out of 143 patients underwent hepatectomy for tumors located in the PC of the liver.

Bisegmentectomy and venous reconstruction after portal vein embolization for the remnant hemiliver in a patient with recurrent colorectal liver metastases.

Repeat hepatectomy for recurrent colorectal liver metastases (CRLM) for the remnant hemiliver is sometimes challenging due to the insufficient future liver remnant (FLR) volume. We present an aggressive strategy for resection of the recurrent CRLM involving bisegmentectomy of the remnant right hemiliver with the aid of portal vein embolization (PVE) and venous reconstruction. The patient was a 50-year-old woman who had undergone left hemihepatectomy for a CRLM 10 months ago.

Direct splenic vein reconstruction combined with resection of the portal vein/superior mesenteric vein confluence during pancreaticoduodenectomy.

Purpose: Splenic vein (SV) ligation combined with portal vein (PV)/superior mesenteric vein (SMV) confluence resection during pancreaticoduodenectomy (PD) is reported to cause left-side portal hypertension (LPH). The purpose of this study was to present our technique of the SV reconstruction and to evaluate the surgical outcomes with/without SV ligation during PD.

Methods: Twenty-four patients undergoing PD with PV and/or SMV resection and being followed over 4 months after surgery between March 2013 and December 2019 in our hospital were evaluated.

Double-Volume Intraoperative Lavage Reduce Bacterial Contamination After Pancreaticoduodenectomy.

Background: To clarify whether double-volume peritoneal lavage can decrease the risk of clinically relevant postoperative pancreatic fistula after pancreaticoduodenectomy.

Materials And Methods: Forty-nine patients who underwent pancreaticoduodenectomy and intraoperative peritoneal lavage using 6000 mL of saline before abdominal closure were studied retrospectively. Bacterial cultures of the lavage fluid were taken twice, after irrigation using 3000 mL of saline and then after an additional 3000 mL of saline.

Differential diagnosis and laparoscopic resection of an adrenal pseudocyst: A case report.

Background: Adrenal pseudocysts are infrequent entities and definite preoperative diagnosis is difficult. We present a case of left adrenal pseudocyst, which was intraoperatively identified as having an adrenal origin and was resected using a laparoscopic approach.

Presentation Of Case: A 41-year-old female was referred to our hospital for examination and treatment of a cystic lesion in the pancreatic tail.

A proposed severity classification system for hepatolithiasis based on an analysis of prognostic factors in a Japanese patient cohort.

Background: Hepatolithiasis frequently results in severe complications. We conducted a cohort study to identify prognostic factors and to establish a hepatolithiasis severity classification system.

Methods: The study cohort comprised 396 patients who were identified through a 1998 nationwide survey and followed up for 18 years or until death.
