High peritoneal incision approach in endoscopic transabdominal preperitoneal patch plasty (TAPP) for inguinal hernia after radical prostatectomy.

Background: Inguinal hernia develops as one of the common complications after robotic or laparoscopic radical prostatectomy (RP). Transabdominal preperitoneal patch plasty (TAPP) for an inguinal hernia after RP is difficult to perform due to postoperative severe adhesions in the preperitoneal cavity. We have introduced a high peritoneal incision approach (HPIA) in TAPP for inguinal hernia patients in whom peritoneal dissection is difficult due to severe adhesions after RP.

Texture analysis using short-tau inversion recovery magnetic resonance images to differentiate squamous cell carcinoma of the gingiva from medication-related osteonecrosis of the jaw.

Objectives: Despite the difficulty in distinguishing between squamous cell carcinoma (SCC) and medication-related osteonecrosis of the jaw (MRONJ) on the basis of medical imaging examinations, the two conditions have completely different treatment methods and prognoses. Therefore, differentiation of SCC from MRONJ on imaging examinations is very important. This study aimed to distinguish SCC from MRONJ by performing texture analysis using magnetic resonance imaging (MRI) short-tau inversion recovery images.

Clinicopathologic differences of gastric neoplasms between Helicobacter pylori-infected and -naïve patients: a multicenter retrospective analysis.

Background: The incidence of gastric neoplasms in Helicobacter pylori (Hp)-naïve patients has recently increased due to a remarkable decrease in the Hp-infected population in Japan. We investigated the clinicopathologic differences between Hp-infected gastric neoplasms (HpIGNs) and Hp-naïve gastric neoplasms (HpNGNs) that have not been fully elucidated so far.

Methods: This retrospective multicenter study investigated 966 consecutive patients with 1131 gastric dysplasia or cancers who underwent endoscopic or surgical treatment for the recent decade.

Background: Duplicated left gastric artery (LGA) is a rare anomaly. With an incidence of only 0.4%, its clinical significance remains largely unrecognized.

Combination of neutrophil-to-lymphocyte ratio and albumin concentration to predict the prognosis of esophageal squamous cell cancer patients undergoing esophagectomy.

Background: Esophageal squamous cell cancer (ESCC) is an aggressive cancer with high incidence and mortality. It is crucial to predict prognosis of these patients individually. Neutrophil-to-lymphocyte ratio (NLR) has been reported as a prognostic indicator in several tumors, including esophageal cancer.

Overlapping Esophagojejunostomy Using a Linear Stapler in Laparoscopic Total or Proximal Gastrectomy.

Performing an intracorporeal esophagojejunostomy during laparoscopic-assisted total or proximal gastrectomy is challenging. We developed an ingenious method of overlapping esophagojejunostomy using a linear stapler to avoid stapler-related intraoperative complications. Following lymph node dissection, the esophagus was transected anterior-posteriorly.

Rational Gastric Conduit Stump Closure Method Using Endo GIA Radial Reload in End-to-Side Anastomosis of the Esophagogastric Conduit.

The lack of tension at the anastomosis site and the blood flow of the gastric conduit are important to prevent anastomotic leakage in the anastomosis of the esophagogastric conduit. This study reports a gastric conduit stump closure method using Endo GIA™ Radial Reload in end-to-side anastomosis of the esophagogastric conduit, especially focusing on blood flow. A 4-cm conduit was created to ensure an intramural vascular network.

Novel inflammation-combined prognostic index to predict survival outcomes in patients with gastric cancer.

Background: We focused on the lymphocyte-to-monocyte ratio (LMR), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) and devised an inflammation-combined prognostic index (ICPI) as a prognostic marker of cancer-specific survival (CSS).

Methods: We reviewed the clinicopathological data of 480 patients with gastric cancer undergoing curative laparoscopic gastrectomy between 2009 and 2019. This study examined the significance of LMR, NLR, PLR, and ICPI as cancer-specific prognostic markers.
