BACKGROUND:  Major bile duct injuries during laparoscopic cholecystectomy (LC), often stemming from errors in surgical judgment and visual misperception of critical anatomy, significantly impact morbidity, mortality, disability, and health care costs.
OBJECTIVE:  To enhance safe LC learning, we developed an educational mobile game, LapBot Safe Chole, which uses an artificial intelligence (AI) model to provide real-time coaching and feedback, improving intraoperative decision-making.
METHODS:  LapBot Safe Chole offers a free, accessible simulated learning experience with real-time AI feedback. Players engage with intraoperative LC scenarios (short video clips) and identify ideal dissection zones. After the response, users receive an accuracy score from a validated AI algorithm. The game consists of 5 levels of increasing difficulty based on the Parkland grading scale for cholecystitis.
RESULTS:  Beta testing (n=29) showed score improvements with each round, with attendings and senior trainees achieving top scores faster than junior residents. Learning curves and progression distinguished candidates, with a significant association between user level and scores (P=.003). Players found LapBot enjoyable and educational.
CONCLUSIONS:  LapBot Safe Chole effectively integrates safe LC principles into a fun, accessible, and educational game using AI-generated feedback. Initial beta testing supports the validity of the assessment scores and suggests high adoption and engagement potential among surgical trainees.

BACKGROUND: The cranial-caudal-medial approach (CCMA) has been proposed for laparoscopic right hemicolectomy nowadays. This study aimed to investigate the safety and oncological efficacy of CCMA in the treatment of right-sided colon cancer compared to the medial-lateral approach (MLA).
METHODS: Patients diagnosed with right-sided colon cancer were included from February 2015 to June 2018, retrospectively, dividing into the CCMA group and the MLA group. We compared the basic characteristics and the short-term and long-term outcomes in two groups.
RESULTS: Two hundred and ninety-six patients were included in this study. The baseline characteristics were similar in two groups. Compared with MLA group, CCMA group exhibited shorter operation time (136.3 ± 25.3 min vs. 151.6 ± 21.5 min, P < 0.001), lower estimated blood loss (44.1 ± 15.2 ml vs. 51.4 ± 26.9 min, P = 0.010), and more harvested lymph nodes (18.5 ± 7.1 vs. 16.5 ± 5.7, P = 0.021). The 5-year overall survival (OS) rate for the CCMA group was 76.5%, and the 5-year disease-free survival (DFS) rate was 72.3%, both of which were not inferior to the MLA group. No significant difference was found between two groups in terms of other clinical parameters.
CONCLUSIONS: The CCMA in laparoscopic right hemicolectomy is safe and feasible, making the anatomical plane clearer. This approach can shorten the operation time, reduce intraoperative blood loss, harvest more lymph nodes, and yield satisfactory oncological outcomes.

Abdominal trauma is common in daily life, but a traumatic abdominal wall hernia (TAWH) in children is rare. A TAWH is caused by a huge external force that leads to subcutaneous muscle and fascia rupture, while the skin remains intact. As abdominal pressure increases, the abdominal contents protrude, forming a lump. A TAWH is highly susceptible to missed diagnosis because of other severe injuries. We report a case of a 2-year-old boy with a TAWH who developed a prominent subcutaneous mass on the right side of his abdomen after abdominal trauma; the size of the mass changed significantly with abdominal pressure and crying. In this case, we used a new approach of laparoscopic suture repair technique with the assistance of a fascial closure device and achieved good results. We found that this method offers the advantages of minimally invasive surgery, fast recovery, and no visible surgical incisions. There was no recurrence after 8 months of follow-up.

BACKGROUND: An intrauterine device (IUD) is a contraceptive device placed in the uterine cavity and is a common contraceptive method for Chinese women. However, an IUD may cause complications due to placement time, intrauterine pressure and other factors. Ectopic IUDs are among the most serious complications. Ectopic IUDs are common in the myometrium and periuterine organs, and there are few reports of ectopic IUDs in the urinary bladder, especially in the anterior wall.
METHODS: A 52-year-old woman was hospitalized due to a urinary bladder foreign body found via abdominal ultrasound and computed tomography (CT) examination. The patient had a 2-year history of recurrent abdominal distension and lower abdominal pain, accompanied by frequent urination, urgency, dysuria and other discomfort. Ultrasound examination revealed foreign bodies in the bladder cavity, with calculus on the surface of the foreign bodies. CT revealed a circular foreign body on the anterior wall of the urinary bladder, suggesting the possibility of an ectopic IUD. After laparoscopic exploration, an annular IUD was found in the anterior wall of urinary bladder, and an oval calculus with a diameter of approximately 2 cm was attached to the surface of the bladder cavity. The IUD and calculus were successfully and completely removed. The patient recovered well after surgery.
CONCLUSIONS: Abdominal ultrasound and CT are effective methods for detecting ectopic IUDs. The IUD is located in the urinary bladder and requires early surgical treatment. The choice of surgical method is determined by comprehensively considering the depth of the IUD in the bladder muscle layer, the situation of complicated calculus, the situation of intravesical inflammation and medical technology and equipment.

OBJECTIVE: We investigate the feasibility, safety, and clinical therapeutic effect of laparoscopic sigmoid vaginoplasty in women with Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome.
METHODS: We performed a retrospective case review cohort study of 56 patients with MRKHs undergoing laparoscopic sigmoid vaginoplasty in Wuhan Union Hospital between 2000 and 2020, and all patients were followed up.
RESULTS: The median operating time was 165 min (120-420 min). The median hospital stay was 10 days (rang 7-15 days). A functional neovagina was created 11-15 cm in length and two fingers in breadth in all patients. No introitus stenosis was observed. No intra- or post-operative complications occurred. Two patients were lost to follow-up after 3 months of outpatient visits. Six patients had no intercourse and were required to wear a vaginal mold occasionally. None of the patients had complained of local irritation or dyspareunia. Patients who had post-surgery sexual intercourse were satisfied with their sexual life and the mean total Female Sexual Function Index (FSFI) score was 25.17 ± 0.63. The cosmetic results were excellent.
CONCLUSIONS: The laparoscopic sigmoid vaginoplasty can achieve the goal of making a functional neovagina. The main advantage of this surgical technique is that it is minimally invasive and that there are fewer complications post-operation. It is an acceptable procedure for patients with MRKH syndrome.

OBJECTIVE: To compare efficacy of proximal and distal laparoscopic ureteroureterostomy (UU) for complete duplex kidneys in children.
METHODS: Patients who underwent laparoscopic UU for complete duplex kidneys between December 2016 and July 2022 were reviewed retrospectively. 71 patients who had normal lower pole moiety without vesicoureteral reflux (VUR) were recruited. All of them underwent ultrasound, voiding cystourethrography (VCUG), renal scintigraphy, and magnetic resonance urography preoperatively. Proximal laparoscopic UU was performed in 35 patients and distal laparoscopic UU in 36 patients. Double J stents were placed in normal lower pole moieties. Clinical data, including general information, diagnosis, surgical management, imaging characteristics, clinical symptoms and postoperative complications (classified according to the modified Clavien-Dindo classification), and length of stay were recorded. Measurement date comparisons between groups were performed by t test, counting date were analyzed by chi-square test.
RESULTS: The study consisted of 71 patients (56 females and 15 males) with complete duplex kidneys (41 in left kidney and 30 in right kidney). The patients\' mean age was 34 m (range 3-161 m) and follow-up ranged from 25 to 81 m. No significant difference was found in age and follow-up time between the two groups. Laparoscopic UU was performed in all patients successfully. The operation time of the two groups was 108.42 ± 26.95 min for distal UU vs 121.46 ± 35.15 min for proximal UU(p = 0.14). No significant difference in postoperative complications was seen between the two groups (22.2% vs 31.4%, p = 0.345). However, in terms of the grading of postoperative complications, the proximal UU group had a higher grade (3 of them had a grade of IV) and more serious complications.
CONCLUSIONS: There was no significant difference in the overall incidence of complications between distal and proximal UU. Compared with proximal laparoscopic UU, distal laparoscopic UU is easier to perform with less injury to the peripheral tissues. Postoperative complications of proximal UU are more serious and more difficult to manage. We recommend complete duplex kidney ureteral reconstruction with distal UU.

Laparoscopic-assisted microwave ablation (LAMWA), as one of the locoregional therapies, has been employed to treat hepatocellular carcinoma (HCC). This study aims to compare the efficacy and safety of LAMWA and laparoscopic hepatectomy in the treatment of small HCC.This study included 140 patients who met the inclusion criteria. Among them, 68 patients received LAMWA and 72 patients underwent laparoscopic hepatectomy. The perioperative condition, liver function recovery, the alpha fetoprotein (AFP) level, morbidities, hospitalization time, overall survival (OS), disease-free survival (DFS) and recurrence rate between the two groups were compared. The rate of complete elimination of tumor tissue was 100% and the AFP level was returned to normal within 3 months after surgery in both groups (P > 0.05). The mean alanine transaminase (ALT) and aspartate transaminase (AST) peak in the LAMWA group was lower than that in the laparoscopic hepatectomy group (259.51 ± 188.75 VS 388.9 ± 173.65, P = 0.000) and (267.34 ± 190.65 VS 393.1 ± 185.67, P = 0.000), respectively. The mean operation time in the LAMWA group was shorter than that in the laparoscopic hepatectomy group (89 ± 31 min VS 259 ± 48 min, P = 0.000). The blood loss in the LAMWA group was less than that in the laparoscopic hepatectomy group (58.4 ± 64.0 ml VS 213.0 ± 108.2 ml, P = 0.000). Compared with the laparoscopic hepatectomy group, patients in the LAMWA group had lower mean hospital stay (4.8 ± 1.2d VS 11.5 ± 2.9d, P = 0.000). The morbidities of the LAMWA group and the hepatectomy group were 14.7%(10/68) and 34.7%(25/72), respectively (P = 0.006). The one-, three-, and five-year OS rates were 88.2%, 69.9%, 45.6% for the LAMWA group and 86.1%, 72.9%, 51.4% for the laparoscopic hepatectomy group (P = 0.693). The corresponding DFS rates for the two groups were 76.3%, 48.1%, 27.9% and 73.2%, 56.7%, 32.0% (P = 0.958). Laparoscopic-assisted microwave ablation is a safe and effective therapeutic option for selected small HCC.

BACKGROUND: The incidence of gastric cancer has significantly increased in recent years. Surgical resection is the main treatment, but the method of digestive tract reconstruction after gastric cancer surgery remains controversial. In the current study, we sought to explore a reasonable method of digestive tract reconstruction and improve the quality of life and nutritional status of patients after surgery. To this end, we statistically analyzed the clinical results of patients with gastric cancer who underwent jejunal interposition double-tract reconstruction (DTR) and esophageal jejunum Roux-en-Y reconstruction (RY).
OBJECTIVE: To explore the application effect of DTR in total laparoscopic radical total gastrectomy (TLTG) and evaluate its safety and efficacy.
METHODS: We collected the relevant data of 77 patients who underwent TLTG at the Fourth Hospital of Hebei Medical University from October 2021 to January 2023. Among them, 35 cases were treated with DTR, and the remaining 42 cases were treated with traditional RY. After 1:1 propensity score matching, the cases were grouped into 31 cases per group, with evenly distributed data. The clinical characteristics and short- and long-term clinical outcomes of the two groups were statistically analyzed.
RESULTS: The two groups showed no significant differences in basic data, intraoperative blood loss, number of lymph node dissections, first defecation time after operation, postoperative hospital stay, postoperative complications, and laboratory examination results on the 1st, 3rd, and 5th days after operation. The operation time of the DTR group was longer than that of the RY group [(307.58 ± 65.14) min vs (272.45 ± 62.09) min, P = 0.016], but the first intake of liquid food in the DTR group was shorter than that in the RY group [(4.45 ± 1.18) d vs (6.0 ± 5.18) d, P = 0.028]. The incidence of reflux heartburn (Visick grade) and postoperative gallbladder disease in the DTR group was lower than that in the RY group (P = 0.033 and P = 0.038). Although there was no significant difference in body weight, hemoglobin, prealbumin, and albumin between the two groups at 1,3 and 6 months after surgery, the diet of patients in the DTR group was better than that in the RY group (P = 0.031).
CONCLUSIONS: The clinical effect of DTR in TLTG is better than that of RY, indicating that it is a more valuable digestive tract reconstruction method in laparoscopic gastric cancer surgery.

OBJECTIVE: To investigate the safety and application value of combining Laennec extracapsular occlusion with ICG fluorescence imaging in laparoscopic anatomic hepatectomy.
METHODS: Complete laparoscopic dissection was performed outside the Laennec sheath, blocking Glisson\'s pedicle of the corresponding liver segment or lobe. An appropriate amount of indocyanine green (ICG) dye was intravenously injected, and the boundary line between the pre-cut liver segment and liver lobe was identified using fluorescence laparoscopy. Complete resection of the liver segment or lobe was performed based on anatomical markers. Clinical data, including operation time, intraoperative blood loss, postoperative hospital stay, and postoperative complications, were collected.
RESULTS: A total of 14 cases were included in the study, including seven cases of primary liver cancer, three cases of metastatic liver cancer, three cases of intrahepatic bile duct calculi, and one case of hepatic hemangioma. All 14 patients underwent anatomic hepatectomy under fluorescent laparoscopy, with four cases involving the right liver, seven cases involving the left liver, two cases involving the right anterior lobe, and one case involving the right posterior lobe.
CONCLUSIONS: Combining laparoscopic follow-up of the Laennec membrane with Glisson outer sheath block and intraoperative ICG fluorescence imaging provides real-time guidance for locating the resection boundaries during anatomic hepatectomy. This approach helps in controlling intraoperative bleeding, reducing operation time, and ensuring high safety. It holds significant value in clinical application.

To evaluate the impact of perioperative comprehensive nursing intervention on postoperative urinary incontinence, various aspects of patient well-being were assessed. The comprehensive group, that received the nursing intervention, demonstrated significant improvements in self-care skills, health knowledge level, self-care responsibility, and self-concept compared to the standard group. The findings indicate that perioperative comprehensive nursing intervention has a remarkable effect on patients undergoing laparoscopic radical prostatectomy. This nursing intervention not only effectively improves postoperative urinary incontinence and alleviates negative emotions, such as anxiety and depression. Therefore, the implementation of this nursing intervention model is highly recommended for clinical practice and wider application.
