Background: Laparoscopic adjustable gastric banding (LAGB) is associated with high long-term failure rates requiring conversion to alternative procedures. Operative conversion to laparoscopic sleeve gastrectomy (LSG) or laparoscopic Roux-en-Y gastric (LRYGB) bypass is associated with higher complication rates than primary procedures.
Objectives: To compare results for converting failed LAGB to LSG versus LRYGB.
Setting: University Hospital, United Kingdom, National Health Service.
Methods: All patients undergoing conversion of LAGB to LRYGB and LSG from July 2006 to September 2012 were included. A retrospective analysis of our prospectively maintained database was performed to identify differences in death rates, complication rates, length of hospital stay, and weight loss. Within this study LRYGB was the preferred choice for conversion and LSG was only considered in the presence of significant intraabdominal adhesions, because of patient choice, or in patients with contraindications to LRYGB.
Results: Eighty-nine patients with failed LAGB underwent conversional surgery within this period. Of these, 64 patients underwent conversion to LRYGB and 25 underwent conversion to LSG. There was no statistical difference in percentage of excess weight loss at 1 or 2 years after conversional surgery to LSG or LRYGB. Conversion to LRYGB was carried out as a single procedure in 51/64 (80%) compared with 10/25 (40%) for conversion to LSG (P = .003). One postoperative complication occurred requiring reoperation after conversion to LRYGB.
Conclusion: There was no difference in complication rates, hospital stay, and early weight loss when converting failed LAGB to LRYGB or LSG. Both procedures are appropriate for conversion from LAGB, although a staged approach is often needed, especially for LSG.

High Incidence of syphilis seroconversion among people living with HIV in Hainan, south China.

Globally, people living with HIV (PLHIV) are at a high risk of syphilis transmission, and Hainan Province has one of the highest syphilis rates in China. However, there is no targeted syphilis screening for HIV patients in Hainan, highlighting the need for data to guide public health interventions. This study aims to assess the incidence of seropositive syphilis and its associated factors among PLHIV.

Introduction: Roux-en-Y gastric bypass (RYGB) reversal might be necessary to alleviate refractory surgical or nutritional complications, such as postprandial hypoglycemia, malnutrition, marginal ulceration, malabsorption, chronic diarrhea, nausea and vomiting, gastro-esophageal reflux disease, chronic pain, or excessive weight loss. The surgical technique of RYGB reversal is not standardized; potential strategies include the following: (1) gastro-gastrostomy: hand-sewn technique, linear stapler, circular stapler; (2) handling of the Roux limb: reconnection or resection (if remaining intestinal length ≥ 4 m).
Case Presentation: We demonstrate the surgical technique of a laparoscopic reversal of RYGB with hand-sewn gastro-gastrostomy and resection of the alimentary limb with the aim of improving the patient's quality of life.
Utility of a novel scoring system for difficulty of pure laparoscopic hepatectomy for intrahepatic cholangiocarcinoma.

Despite the growing adoption of laparoscopic hepatectomy (LH) for intrahepatic cholangiocarcinoma (ICC), there is no scoring system available designed to evaluate its surgical complexity. This paper aims to introduce a novel difficulty scoring system (DSS), designated as the Wei-DSS, exclusively tailored to assess the surgical difficulty of pure LH for ICC. We retrospectively collected clinical data from ICC patients who underwent pure LH at our institution, spanning from November 2018 to May 2024.

Objective: This study aims to enhance compliance with lower limb lymphedema (LLL) prevention care measures post-gynecologic oncology surgery (GOS) through quality control circle (QCC) activity, aiming to improve patient recovery outcomes and reduce postoperative complications.
Methods: A 6-month QCC activity was conducted within the hospital, employing the ten-step plan-do-check-act model for QCC activity. The root causes of inadequate implementation of LLL prevention care measures were analyzed, leading to the development of relevant strategies and protocols.

Objectives: Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide, particularly among the elderly, resulting in high rates of intensive care unit (ICU) admissions. Malnutrition is common in elderly patients and has been associated with poor prognosis in patients with COPD. However, its impact in the ICU setting remains incompletely defined.
