Background: Gallbladder drainage procedures are often considered for acute cholecystitis (AC) patients with significant peri-operative risks. While percutaneous transhepatic gallbladder drainage (PTGBD) has been evaluated in previous studies, there is scarce data on the feasibility and efficacy of endoscopic transpapillary gallbladder stenting (ETGBS) in patients with AC. This study aimed to compare the characteristics of interval cholecystectomy following ETGBS and PTGBD.

The accurate diagnosis and therapeutic strategies of thyroglossal duct cysts (TGDCs) are challenging for surgeons if the opening with exudate is far from the hyoid bone. A 7-year-old boy presented with a right supraclavicular mass and persistent pus. Ultrasonography and magnetic resonance imaging revealed the fistula to the hyoid bone.

The ideal management of perforated colorectal cancer in the hernia sac remains a challenge for general surgeons. We report such a case requiring a combined-incision surgical approach and two-stage operation. A male patient in his 80s presented with fatigue and a bulge in his left groin.

Introduction: Fetal intestinal volvulus without malrotation is extremely rare, and early prenatal diagnosis is challenging because the signs and symptoms are non-specific. However, without proper management, it can cause massive bowel necrosis.

Presentation Of Case: A woman experienced a dilated fetal bowel at 34 weeks of pregnancy and noticed a decrease in fetal movements at 36 weeks; however, she did not visit a hospital.

Aim: Our aim was to investigate the predictive factors for Hartmann's reversal and to describe the differences in the rates and timings of Hartmann's reversal for various causative diseases.

Method: In this multicentre retrospective cohort study patients who underwent Hartmann's procedure (HP) between 2006 and 2018 were enrolled. To describe the demographic patterns of Hartmann's reversal through to 2021, we analysed the cumulative incidence rate of Hartmann's reversal over time based on the Kaplan-Meier failure estimate.

Background: Severe adhesions and fibrosis between the posterior wall of the gallbladder and liver bed often render total cholecystectomy after percutaneous transhepatic gallbladder drainage (PTGBD) difficult, leading to high open conversion rates. Since the publication of Tokyo Guidelines 2018 (TG18), our policy has shifted from open conversion to subtotal cholecystectomy (SC) when total laparoscopic cholecystectomy for difficult cases of cholecystitis is not feasible. Recently, SC has been frequently applied as bailout surgery for complicated cholecystitis.

Background: Hemostatic resuscitation strategy using blood components with a balanced ratio is adopted in the civilian trauma setting. However, there is usually limited availability of blood components in the austere setting. Warm fresh whole blood (WFWB) has been used for trauma patients with life-threatening hemorrhage necessitating massive transfusions in the Okinawa Islands, Japan.

Purpose: We aimed to examine the association between contrast extravasation (CE) on initial computed tomography (CT) scan and pseudoaneurysm (PSA) development in pediatric blunt splenic and/or liver injury.

Methods: We conducted a multi-institutional retrospective study in cases of blunt splenic and/or hepatic injury who underwent an initial attempt of nonoperative management. A logistic regression model was used to compare PSA formation and CE on initial CT scan, and the area under the receiver operating characteristic curve (AUC) with and without CE was used to assess the predictive performance of CE for PSA formation.

We report a case of locally recurrent anorectal cancer treated with proton beam therapy (PBT) alone that led to a clinically complete response. A 70-year-old woman with paraparesis due to infantile paralysis underwent abdominoperineal resection (APR) and D3 lymphadenectomy for anorectal cancer (PERb, type 2, 50×40 mm, muc-tub1, M1a[lung], Stage IV a]. Three months after APR, right middle and right lower lobectomies were performed for synchronous lung metastases.
