A Case of Pancreaticoduodenectomy for Grade V Traumatic Pancreatic Injury in an Elderly Patient.

Traumatic pancreatic injury is a rare condition, but cases involving main pancreatic duct injury often require surgical intervention and are associated with high mortality rates. Recently, two-stage surgical approaches, with initial damage control surgery followed by delayed pancreatic resection and reconstruction, have been increasingly reported. However, we argue that not all cases need a two-stage approach; instead, surgical strategies should be tailored based on the patient's vital signs.

Short- and long-term outcomes of laparoscopic radical gallbladder resection for gallbladder carcinoma: A multi-institutional retrospective study in Japan.

Background/purpose: Laparoscopic resection of gallbladder carcinomas remains controversial. This study aimed to evaluate the surgical and oncological outcomes of laparoscopic procedures for suspected gallbladder carcinoma (GBC).

Methods: In this retrospective study, data regarding suspected GBC treated with laparoscopic radical cholecystectomy before 2020 in Japan, was included.

Is frequent measurement of tumor markers beneficial for postoperative surveillance of colorectal cancer?

Purpose: To determine whether frequent measurement of tumor markers triggers early detection of colorectal cancer recurrence.

Methods: Of 1,651 consecutive patients undergoing colorectal cancer surgery between 2010 and 2016, 1,050 were included. CEA and CA 19-9 were considered to be postoperative tumor markers and were measured every 3 months for 3 years, and then every 6 months for 2 years.

An International Retrospective Observational Study of Liver Functional Deterioration after Repeat Liver Resection for Patients with Hepatocellular Carcinoma.

Whether albumin and bilirubin levels, platelet counts, ALBI, and ALPlat scores could be useful for the assessment of permanent liver functional deterioration after repeat liver resection was examined, and the deterioration after laparoscopic procedure was evaluated. For 657 patients with liver resection of segment or less in whom results of plasma albumin and bilirubin levels and platelet counts before and 3 months after surgery could be retrieved, liver functional indicators were compared before and after surgery. There were 268 patients who underwent open repeat after previous open liver resection, and 224 patients who underwent laparoscopic repeat after laparoscopic liver resection.

The necessity of intensive surveillance colonoscopy for patients with a remaining right colon after resection of colorectal cancer: a retrospective cohort study.

Purpose: To clarify how often postoperative surveillance colonoscopy should be undertaken based on the risk factors for the development of metachronous cancer (MC) and advanced adenoma (AA) after surgery for colorectal cancer.

Methods: We collected data of consecutive patients who underwent curative resection for primary colorectal cancer between 2005 and 2012, with preoperative colonoscopy and surveillance colonoscopy at 1 year after surgery (406 patients, mean age: 69 years, 59% male). The detection rates of AA (with villous features, > 10 mm or high-grade dysplasia) and MC by surveillance colonoscopy were the primary outcomes.

Multicenter Propensity Score-Based Study of Laparoscopic Repeat Liver Resection for Hepatocellular Carcinoma: A Subgroup Analysis of Cases with Tumors Far from Major Vessels.

Less morbidity is considered among the advantages of laparoscopic liver resection (LLR) for HCC patients. However, our previous international, multi-institutional, propensity score-based study of emerging laparoscopic repeat liver resection (LRLR) failed to prove this advantage. We hypothesize that these results may be since the study included complex LRLR cases performed during the procedure's developing stage.

Should Lymph Nodes Be Retrieved in Patients with Intrahepatic Cholangiocarcinoma? A Collaborative Korea-Japan Study.

Background: This study was performed to investigate the oncologic role of lymph node (LN) management and to propose a surgical strategy for treating intrahepatic cholangiocarcinoma (IHCC).

Methods: The medical records of patients with resected IHCC were retrospectively reviewed from multiple institutions in Korea and Japan. Short-term and long-term oncologic outcomes were analyzed according to lymph node metastasis (LNM).

Impact of vascular abnormality on contrast-enhanced CT and high C-reactive protein levels on postoperative pancreatic hemorrhage after pancreaticoduodenectomy: A multi-institutional, retrospective analysis of 590 consecutive cases.

Background: /Objectives: This study aimed to elucidate the efficacy of CT findings and perioperative characteristics to predict post-pancreatectomy hemorrhage (PPH): a critical complication after pancreaticoduodenectomy.

Methods: The records of 590 consecutive patients who underwent pancreaticoduodenectomy at three institutes between 2012 and 2018 were included. The presence of a vascular wall abnormality or ascites with high density (vascular abnormality) on postoperative day (POD) 5-10 contrast-enhanced CT (early CT), perioperative characteristics, and any PPH or pseudoaneurysm formation (PPH events) were analyzed through a multivariate analysis.

[Sigmoid Colon Cancer with Lateral Lymph Node Metastasis That Presented with Gastric Perforation].

A 74-year-old man visited his local clinic complaining of abdominal pain that persisted for three days. He was diagnosed with diffuse peritonitis and was transported to our hospital. Contrast computed tomography(CT)showed gastric perforation and a tumor in the sigmoid colon with left obturator lymph node metastasis.

Strangulated Hernia Can Be a Risk Factor of Seroma following Laparoscopic Transabdominal Preperitoneal Repair.

Purposes: Seroma is a postoperative complication following laparoscopic transabdominal preperitoneal repair (TAPP) for inguinal hernioplasty. Seroma naturally resolves in most cases, but it can lead to an increased amount of visits to the outpatient clinic and can result in anxiety of the patient. Local inflammation of the inguinal area is etiology of seroma formation.

Feasibility of a novel tacking method of securing mesh in transabdominal preperitoneal inguinal hernia repair: Secure tacking against recurrence.

Introduction: Postoperative chronic pain is an important outcome of hernia surgery. In laparoscopic hernia surgery, either fixation outside the trapezoid of disaster or no fixation is recommended to avoid postoperative pain. To avoid recurrence are transabdominal preperitoneal (TAPP) hernia repair, the myopectineal orifice must be covered with mesh during TAPP, but lifting or shrinking of the mesh can lead to recurrence.

The feasibility and efficacy of pure laparoscopic repeat hepatectomy.

Background: Repeat hepatectomy is often required for hepatocellular carcinoma and metastatic tumors. However, this procedure is technically challenging, so laparoscopic repeat hepatectomy (LRH) has not been widely adopted. The aim of this study was to evaluate the feasibility and efficacy of LRH compared with open repeat hepatectomy (ORH) and laparoscopic primary hepatectomy (LPH).

The safety and efficacy of laparoscopic hepatectomy in obese patients.

Background: Obesity is generally reported to increase the risk of surgical complications. There have been few reports of laparoscopic hepatectomy (LH) in obese patients. The purpose of this study was to compare the safety and efficacy of (1) LH versus open hepatectomy (OH) in obese patients and (2) LH in obese patients versus LH in non-obese patients.

Feasibility of Endo GIA™ Reinforced Reload with Tri-Staple™ Technology for delta-shaped anastomosis.

Background: We report the short-term clinical outcomes of a delta-shaped (DS) anastomosis in laparoscopic distal gastrectomy (LDG), comparing Endo GIA™ Reinforced Reload (Reinforced GIA) with Endo GIA™ (GIA) staplers.

Methods: This was a retrospective analysis of 40 patients who underwent totally LDG with DS anastomosis with Reinforced GIA (group A) and 90 patients who underwent the same procedure with GIA (group B) for clinical T1-T3 gastric cancer from May 2013 to December 2016. Operation time, intraoperative blood loss, hospital length of stay, reconstruction time, and complications were compared.

Laparoscopic approach to suspected T1 and T2 gallbladder carcinoma.

Aim: To evaluate a laparoscopic approach to gallbladder lesions including polyps, wall-thickening lesions, and suspected T1 and T2 gallbladder cancer (GBC).

Methods: We performed 50 cases of laparoscopic whole-layer cholecystectomy (LCWL) and 13 cases of laparoscopic gallbladder bed resection (LCGB) for those gallbladder lesions from April 2010 to November 2016. We analyzed the short-term and long-term results of our laparoscopic approach.

Laparoscopic radical antegrade modular pancreatosplenectomy for left-sided pancreatic cancer using the ligament of Treitz approach.

Background: Laparoscopic distal pancreatectomy (Lap-DP) for benign lesions or those with low malignant potential has been proven safe and effective, and its performance is now widespread [1-3]. Lap-DP for left-sided pancreatic cancer (PC) is also being increasingly performed. According to some reports, Lap-DP has superior short-term outcomes (blood loss, postoperative hospital stay) and comparable oncological outcomes and overall survival with those of open distal pancreatectomy (Op-DP) [4-6].

Feasibility of a new approach for creating a preperitoneal space in transabdominal preperitoneal repair inguinal hernia repair: using a sandwich approach.

Purpose: In Japan, transabdominal preperitoneal (TAPP) inguinal hernia repair is performed by firmly pulling the peritoneum inwards to lift it from the underlying deep layer of subperitoneal fascia. It decreases the postoperative pain and discomfort in the inguinal area. The aim of this study was to evaluate the feasibility of the sandwich approach, which is a new technique for creating a preperitoneal space.

Laparoscopic and Endoscopic Cooperative Surgery for Plexiform Angiomyxoid Myofibroblastic Tumor.

Plexiform angiomyxoid myofibroblastic tumor (PAMT) is a recently described distinctive gastric mesenchymal entity with a peculiar plexiform pattern, bland spindle cells and a myxoid stroma rich in arborizing blood vessels. In this study, we report a new case of this rare gastric tumor resected by laparoscopic and endoscopic cooperative surgery (LECS). A 39-year-old Japanese man was admitted with a gastric mass.
