Parasitic dermoid cysts may form from autoamputation of the ovarian mass secondary to torsion or rupture. It may then reimplant in surrounding structures and undergo subsequent neovascularization and further growth. The true incidence of these cases is unknown, however, a study reported a 0.04% incidence among 1,007 cases of dermoid cysts. This report describes the case of a 30-year-old multigravida who presented with an ultrasound finding of an ovarian dermoid cyst, which, upon laparoscopic surgery, turned out to be a parasitic dermoid cyst adherent to the bladder, with grossly normal bilateral ovaries. Theories on the development of parasitic dermoid cyst are also presented.

With advancements in surgical technology, minimally invasive and function- preserving approaches have become fundamental objectives of both patients and physicians. In recent years, laparoscopic endoscopic cooperative surgery (LECS) has gained increasing attention for its significant role in achieving these goals. However, a notable gap remains in the availability of evidence-based guidelines to standardize the clinical implementation of LECS for gastrointestinal tumors. This guideline is collaboratively developed by the Gastrointestinal Stromal Tumor Committee of the Chinese Anti-Cancer Association, Chinese Gastric Cancer Association, the NOTES Group of the Digestive Endoscopy Branch of the Chinese Medical Association, and the Greater Bay Area Laparoscopic Endoscopic Cooperative Surgery Alliance. Through integrating the current best evidence and experts' opinions, we developed 22 recommendations on 16 clinical questions, including the LECS indications, use of antibiotics, enhanced recovery after surgery, wound suture, and surgical training. This guideline provides comprehensive guidance and recommendations for LECS, aimed at promoting the precise, minimally invasive and function-preserving treatment of gastrointestinal tumors.

The incidence of hiatal hernia is on the rise due to population aging and improved awareness of the disease. Laparoscopic repair is the main treatment modality; however, there remains a lack of consensus on the selection of mesh materials and operative specifications. Based on high-level evidence, this expert consensus has formulated 11 recommendations regarding the indications for mesh application, material selection, and operative methods: For patients with giant hiatal hernias (defect area >10 cm², hiatal diameter ≥ 5 cm, or over 1/3 of the gastric body entering the thoracic cavity), complex hernias, recurrent hernias, or those with weak diaphragmatic crura, mesh-reinforced repair is recommended to reduce the risk of recurrence. Synthetic meshes are suitable for giant/complex hernias; biological meshes help reduce foreign body reactions; and bioabsorbable synthetic meshes combine mechanical strength with safety. The preferred shape of the mesh is U-shaped, and fixation methods (non-absorbable sutures, absorbable staplers, or medical adhesives) are selected based on hernia size and anatomical features. For suturing the diaphragmatic crura, non-absorbable sutures are recommended, with the choice between interrupted or continuous suturing techniques tailored to patient characteristics. The method of fundoplication is determined according to esophageal pH measurement and lower esophageal sphincter pressure, and non-absorbable sutures are recommended for plication.

Objective: To investigate the feasibility and safety of modified interposed jejunal anastomosis following total laparoscopic proximal gastrectomy. Methods: The modification in the digestive tract reconstruction involves transecting the small intestine 2-3 cm below the gastrojejunostomy site and relocating the enteroenterostomy cranially, based on the double-tract anastomosis technique. Specifically, the jejunum and its mesenteric vessels are transected 20-25 cm from the ligament of Treitz. An overlap anastomosis is performed between the esophagus and the distal jejunum, with the common opening closed using a 15 cm barbed suture in a buried manner. A side-to-side gastrojejunostomy is completed under natural anatomical alignment, and the common opening is closed similarly. A side-to-side anastomosis is then created between the small intestine approximately 10 cm below the gastrojejunal anastomosis and the small intestine distal to the ligament of Treitz. Finally, the small intestine is transected 2-3 cm below the gastrojejunal anastomosis without dividing the mesenteric vessels. Results: From April to December 2024, a total of five patients with adenocarcinoma of the esophagogastric junction underwent modified interposed jejunum anastomosis following totally laparoscopic proximal gastrectomy at the Affiliated Tumor Hospital of Xinjiang Medical University. The median age of the group was 56 (53-74) years, including four males and one female, with a median body mass index of 24 (21-29) kg/m². Three cases were classified as Siewert type II and two as type III. All five patients successfully completed the totally laparoscopic proximal gastrectomy with modified interposed jejunum anastomosis. The median operative time was 215 (165-240) minutes, the digestive tract reconstruction time was 75 (65-93) minutes, and the intraoperative blood loss was 50 (30-100) ml. The median time to postoperative flatus was 71 (68-88) hours, with no severe complications occurring in any case. The median postoperative hospital stay was 8 (8-9) days. Within three months after surgery, none of the patients reported reflux symptoms such as acid regurgitation or heartburn. Conclusions: Total laparoscopic modified interposed jejunal anastomosis is safe and feasible, with relatively simple operative steps. It effectively prevents reflux while ensuring the passage of food through the remnant stomach and duodenal loop.

OBJECTIVE: To investigate the safety and prognostic factors influencing the treatment of upper urinary tract urothelial carcinoma (UTUC) combined with bladder cancer (BCa) by laparoscopic simultaneous radical cystectomy and nephroureterectomy (RCNU). METHODS: The clinical data of patients admitted to Peking University Third Hospital for laparoscopic RCNU surgery from January 2009 to September 2023 were analyzed retrospectively. Based on the same gender, age (±5 years), history of uroepithelial tumors, underlying diseases, T-stage, N-stage, M-stage, American Society of Anesthesiologists (ASA) score, Charlson comorbidity index, and body mass index (BMI) (±5), 34 patients with RCNU were matched 1 ∶1 with patients with bladder cancer who underwent laparoscopic radical cystectomy (RC) alone. Kaplan-Meier survival analysis was used to calculate patient survival, and Cox proportional regression risk model was used to analyze clinical factors affecting prognosis. RESULTS: Of the 68 patients enrolled, the follow-up rate was 100% with a median follow-up time of 27.0 (11.7, 60.2) months. Comparison of intraoperative conditions (including operation time, estimated intraoperative bleeding, intra-operative blood transfusion, etc.) between the two groups of patients showed no significant difference (P>0.05). Comparison of preoperative creatinine and postoperative creatinine between the two groups of patients showed significant differences (P < 0.05). The perioperative Clavien grade Ⅲ-Ⅳ complication rates were 2.9% (1/34) in the RC group and 5.9% (2/34) in the RCNU group. There was no significant difference in terms of perioperative complications between the two groups. Overall survival was significantly lower in the patients receiving RCNU compared with the matched group receiving RC alone (P < 0.05). Cox regression analysis suggested that two factors, high N stage and high postoperative creatinine, were independent risk factors affecting the prognosis of patients in the 2 groups (P < 0.05). CONCLUSION The overall survival prognosis of patients undergoing RCNU surgery was worse compared with laparoscopic RC surgery alone during the same period. There was no clinically significant difference between the two groups in terms of operation time, intraoperative bleeding, and perioperative complications, and there were clinically significant differences in preoperative renal function and post-operative renal function.

Bariatric and metabolic surgery has become a primary treatment for decompensated obesity, with the number of procedures rapidly increasing in China in recent years. Various improved and novel surgical techniques have emerged. Given the characteristics of the Chinese obese population lower body mass index compared to Western populations and frequent pancreatic islet dysfunction laparoscopic Roux-en-Y gastric bypass remains one of the mainstream procedures in China. Although the Procedural Guideline for Laparoscopic Roux-en-Y Gastric Bypass (2019 Edition) has provided standardized surgical steps, mastering and routinely implementing the procedure in clinical practice continues to pose significant challenges. Compared to laparoscopic sleeve gastrectomy, laparoscopic Roux-en-Y gastric bypass is more technically demanding and requires a longer learning curve. To avoid suboptimal weight loss or severe postoperative complications resulting from non-standardized techniques, this article summarizes the authors' clinical experience, emphasizing key technical steps: creation of the gastric pouch, standardization of gastrojejunal and jejunojejunal anastomoses, hiatal closure, and full serosalization. These insights aim to improve procedural safety and therapeutic efficacy by offering a set of practical process optimization strategies.

Pneumothorax during pediatric laparoscopic surgery is a potentially fatal complication that may not be promptly recognized. It can occur due to congenital anatomical abnormalities, pre-existing pulmonary disease, or operative factors during laparoscopy. Clinical presentation may range from asymptomatic to acute respiratory distress, pleuritic chest pain, and even life-threatening circulatory collapse. Here, we report a case of sudden intraoperative pneumothorax accompanied by extensive subcutaneous emphysema of the neck and chest wall during laparoscopic high ligation of the hernial sac in a child. The child presented with a reducible left lower abdominal mass and mild pain 3 days prior but did not seek medical attention. Symptoms worsened 1 day prior to admission, with difficulty reducing the mass. On April 8, 2021, the patient was admitted to the Department of Anesthesiology, Zhuzhou Hospital Affiliated to Xiangya School of Medicine of Central South University, with a diagnosis of "left inguinal hernia." On the second day of hospitalization, laparoscopic high ligation of the left inguinal hernia sac was performed under general anesthesia. During the procedure, the patient developed a sudden increase in airway pressure, marked hemodynamic fluctuations, crepitus in the neck and right anterior chest regions, and significantly diminished breath sounds in the right lung. Emergent bedside chest X-ray confirmed a right-sided pneumothorax. Immediate intervention including thoracic needle decompression, closed thoracic drainage, the lung re-expansion was performed. The patient was discharged on the 7th postoperative day with full recovery. This case highlights the need for clinicians to remain vigilant for iatrogenic pneumothorax during pediatric laparoscopic surgery. Close intraoperative monitoring of vital signs is crucial for early detection, recognition, and timely management of pneumothorax to ensure patient safety during minimally invasive procedures.

BACKGROUND

Appendicitis is the most common acute surgical disease in children. Due to a nonspecific presentation and progression of the disease, a significantly higher presentation of appendiceal perforation may be expected in young children. With perforation there is an elevated risk of intraabdominal abscess, wound infection, post-operative ileus, higher rates of readmission and longer length of stay. Laparoscopic appendectomy is the recommended first line treatment however many centers from developing countries are still in the early stages of adopting such an approach and do appendectomies in an open manner. This study outlines our institution’s experience with a laparoscopy-first approach in managing pediatric appendicitis. Surgical outcomes from laparoscopic and open procedures during the study period will be compared.

This retrospective cohort analysis encompasses all pediatric appendicitis cases at our institution from 2022 to 2023. As a major pediatric surgery referral center, there were a total of 273 cases during that period. Patient records were reviewed for surgical approach and outcomes.

The mean patient age was 11.87 years with a male:female ratio of 1.84. Average duration of symptoms prior to consult was 2.47 days. Most of the patients had complicated appendicitis (57.8% ruptured, 10.2% gangrenous). For the surgical approach, 42.9% underwent open appendectomy (OA) and 57.1% had LA with a conversion rate of 7.14%. Irrespective of disease severity, LA was superior to OA in terms of time to resume feeding (2.84 vs 4.07 days), post-op length of stay (5.29 vs 6.95 days), and surgical site infection rate (3.3% vs 16.2%). Operative times were not statistically different, with cases performed by fellows being faster than their resident counterparts by a few minutes. Other morbidities for LA included intraabdominal abscess (1.9%) and postoperative adhesions requiring adhesiolysis (1.3%), while the OA group reported 1 case each for adhesions, intraabdominal abscess, and incisional hernia.

This study highlights the advantages and complications of laparoscopic appendectomy in the pediatric population as implemented in a tertiary government center. It also provides preliminary data on a significant cohort of patients with complicated appendicitis who underwent laparoscopic management in the local setting.

We present the case of a 51-year-old man with an incarcerated left inguinoscrotal hernia. He underwent a successful reduction of the incarcerated hernia at the ER and was admitted for elective hernia repair before discharge. Several hours after admission, re-incarceration of the hernia occurred. At that time, it was non-reducible. Informed consent was secured, and he underwent successful emergency laparoscopy assisted reduction of the incarcerated hernia followed by LAPEC. In this particular case, the reduction of the hernia was more challenging than the LAPEC. There were no intraoperative and post operative complications noted. On post operative physical examination, documented by photographs, no evidence of a previous large inguinoscrotal mass can be traced. The patient was discharged on POD 2 and followed up at 1 week and 5 months. No evidence of recurrence was documented on follow up, cosmesis was excellent and there were no pain-related issues reported.

Laparoscopy assisted percutaneous extraperitoneal closure can be a safe, cosmetic, and effective surgical treatment in adults with reducible incarcerated indirect inguinal hernia. The procedure is simple, quick and easy to perform. Our study is the first to report the application of LAPEC in an adult patient with Incarcerated inguinal hernia.
