ERlow breast cancer showed distinct clinicopathological features. ERlow tumors seemed to have higher recurrence rates compared to ERhigh tumors, and they showed no significant benefit from hormonal therapy. Future large scale prospective studies are necessary to validate the treatment options for ERlow breast cancer.

Extended cholecystectomy including LND without liver resection may be a reasonable treatment option for selected T2 GBC patients.

<i>Background and Objectives</i>: Laparoscopic liver resection (LLR) is now widely recognized as the primary surgical option for hepatocellular carcinomas (HCC) smaller than 3 cm located in the left lateral segment of the liver. Nevertheless, there is a scarcity of studies comparing laparoscopic liver resection with radiofrequency ablation (RFA) in these cases. <i>Materials and Methods</i>: We retrospectively compared the short- and long-term outcomes of Child-Pugh class A patients who underwent

Laparoscopic sleeve gastrectomy is the most frequently performed surgical intervention in patients with morbid obesity. Single-port sleeve gastrectomy (SPSG) and reduced-port sleeve gastrectomy (RPSG) are increasingly reported in the literature. This study compared the short-term outcomes of SPSG, RPSG, and conventional laparoscopic sleeve gastrectomy (CLSG). This is a single-center retrospective study of 238 morbidly obese patients, of whom 148 (62.2%) patients completed follow-up one year afte

Body habitus was not significantly associated with operative time and postoperative complications in patients undergoing BABA robotic thyroidectomy, indicating that this approach is safe and feasible in obese patients.

At present, TO only consider surgeon-related factors. However, it is important to include the patient's perspective when defining TO. Although TO were recently applied to laparoscopic hepatectomy, there is still a need to further evaluate their application in this setting. Achieving TO was shown to have a positive impact on long-term outcomes and this needs to be studied for different liver resection procedures.

This rare case demonstrates the importance of considering foreign body penetration as a cause of pyogenic liver abscess, particularly in abscesses of unknown origin that are resistant to antibiotic therapy. Clinical suspicion, early diagnosis, and prompt removal of the foreign body could lead to improved outcomes in these patients.

After DP, the incidence of CR-POPF in the high and low DFA groups was similar and drain malposition increased the risk of CR-POPF. Thus, the ISGPS definition of POPF based on DFA levels is limited in DP, and DFA levels should be interpreted together with the drain position.

Background and Objectives: A difficulty scoring system was previously developed to assess the difficulty of laparoscopic liver resection (LLR) for liver tumors; however, we need another system for hepatolithiasis. Therefore, we developed a novel difficulty scoring system (nDSS) and validated its use for predicting postoperative outcomes. Materials and Methods: This was a retrospective study. We used clinical data of 123 patients who underwent LLR for hepatolithiasis between 2003 and 2021. We ana

The results indicate that laparoscopic reoperation for postoperatively diagnosed T2 GBC has favorable postoperative outcomes and similar oncologic safety compared with open operation.

Background and Objectives: The feasibility of laparoscopic liver resection (LLR) for centrally located hepatocellular carcinoma (cHCC 1 cm of the hilum, major hepatic veins, and inferior vena cava) is still controversial. This study aims to evaluate the feasibility and safety of LLR for cHCC and compare the perioperative outcomes with those of open liver resection (OLR). Materials and Methods: This retrospective study included 110 patients who underwent LLR (n = 59) or open liver resection (OLR)

Achieving textbook outcomes (TOs) improves the short-term and long-term performance of a hospital. Our objective was to assess TOs in the laparoscopic liver resection (LLR) of tumors in the PS (posterosuperior) section of the liver and identify the impact of the learning curve. We conducted a retrospective cohort study analyzing patients who underwent LLR for lesions located in the PS segments. Patients were divided into a TO and no-TO group. TOs were defined as negative margins, no transfusion,

SH for recurrent tumors after ablation showed safety and effectiveness equivalent to primary resection. As recurrent tumors show a higher grade and more aggressive behavior, more extensive resections with wide surgical margins are necessary to prevent recurrence.
