A Classification System Specific for Recurrent Inguinal Hernia Following Open Hernia Surgery.

Background/aim: Currently, there is no classification system specializing in recurrent inguinal hernia (RIH) after open-surgery. For this reason, in this study we proposed one so as to understand the causes of RIH.

Patients And Methods: Recurrence of IH after suture-repair was classified either as the tissue-loosening (TL) or the tissue-disruption (TD) type.

Psoas muscle depletion during preoperative chemotherapy for advanced gastric cancer has a negative impact on long-term outcomes after gastrectomy.

Aim: The significance of sarcopenia in cancers has been widely recognized. However, few studies have focused on chronological changes in sarcopenia in cancer patients. This study aimed to clarify the clinical significance of changes in the psoas muscle area before and after preoperative chemotherapy.

Treatment of acute exacerbation of liver-cirrhosis-associated portal vein thrombosis with direct-acting oral anticoagulant, edoxaban, used as an initial treatment in the early postoperative period after abdominal surgery: a case report.

Background: Cirrhosis-associated portal vein thrombosis (CA-PVT) has been reportedly observed in 5-30% of cirrhotic patients. Moreover, the acute exacerbation of CA-PVT is likely to occur after certain situations, such as a status after abdominal surgery. Safety and efficacy of the direct-acting oral anticoagulant (DOAC) used for cirrhotic patients have been being confirmed.

Subcutaneous switching suture technique for hernia defect closure during laparoscopic ventral and incisional hernia repair.

Introduction: A vertical penetration of the thread through the abdominal wall for the hernia defect closure in laparoscopic ventral/incisional hernia repair (LVIHR) is difficult especially in the large defect cases when applying the existing techniques.

Materials: Sixteen LVIHRs were performed using the suture technique for defect closure we newly developed.

Surgical Technique: With the subcutaneous switching, our technique only requires the suture-passer and easily enables the vertical penetration of the thread through the abdominal muscular wall even in the large defect cases.

Completely laparoscopic repair for recurrent inguinal hernia that developed after open posterior mesh repair.

Surgeons tend to avoid performing completely laparoscopic repair (CLR) for recurrent inguinal hernia (RIH) that developed after the open posterior mesh repair (OPMR). For many, totally extraperitoneal repair or transabdominal preperitoneal repair after OPMR seems difficult because the previously placed mesh may pose an obstacle during the exfoliation of the parietal peritoneum. Moreover, these procedures could cause chronic pain if the "trapezoid of disaster" is injured.

Impact of intramuscular adipose tissue content on short- and long-term outcomes of hepatectomy for colorectal liver metastasis: a retrospective analysis.

Background: Numerous reports regarding sarcopenia have focused on the quantity of skeletal muscle. In contrast, the impact of the quality of skeletal muscle has not been well investigated.

Methods: A retrospective analysis of 115 patients who underwent initial hepatectomy for colorectal liver metastasis between January 2009 and December 2016 in our hospital was performed.

[Remarkable Response to Trastuzumab Observed in a Case of Gastric Cancer with HER2-Negative Conversion].

A 64-year-old woman was diagnosed with advanced gastric cancer with solitary liver metastasis. Although the HER2 status of the tumor was IHC2+, no further examination for HER2 status using FISH was performed. Four courses of S-1 and cisplatin chemotherapy were administered.

Bowel strangulation caused by massive intraperitoneal adhesion due to effective chemotherapy for multiple peritoneal metastases originating from descending colon cancer.

We describe a case of bowel strangulation caused by massive peritoneal adhesion as a result of effective chemotherapy. A 71-year-old man, who had obstructive descending colon cancer with massive peritoneal metastases and, therefore, received palliative surgery consisting of diverting colostomy and sampling of peritoneal nodules, developed bowel strangulation on day 4 of the 2nd course of chemotherapy, including irinotecan, l-leucovorin, and 5-fluorouracil. Emergent celiotomy showed a massive intraperitoneal adhesion formed around several intestinal loops, which were not observed at the prior surgery.

[A Case of Resected Gastric Cancer Invading the Esophagus with Esophageal Recurrence That Responded to Weekly Docetaxel／Cisplatin Chemotherapy].

A 77-year-old man underwent total gastrectomy with D1+ lymph node dissection after being diagnosed with cT4aN2M0, cStage ⅢB gastric cancer. Peritoneal dissemination was detected in the bursa omentalis. The pathological diagnosis after surgery was pT4aN3b (21/41) M1 (P1).

[A Case of Mucinous Cystadenocarcinoma of the Retroperitoneum Supposed to Be Derived from Ectopic Ovarian Tissue].

Most tumors arising in the retroperitoneum are non-epithelial, and epithelial tumors are very rare. We report a case of mucinous cystadenocarcinoma of the retroperitoneum supposed to be derived from ectopic ovarian tissue. A 56-year-old woman was admitted to the hospital because of abdominal distention, and an abdominal CT scan revealed a cystic tumor of the right lower retroperitoneum.
