ABSTRACT

Background: Since Langenbuch's pioneering open cholecystectomy in 1882, surgical approaches to gall bladder diseases have seen continual evolution. Laparoscopic surgery has emerged as the preferred method for treating benign gall bladder conditions, offering benefits like decreased postoperative discomfort and enhanced cosmetic outcomes. Variations to the traditional four-port laparoscopic cholecystectomy have been developed to further refine the procedure. Methods: A comparative randomized study was carried out at the Department of Surgery, Govt. Medical College and Hospital Jammu, spanning from November 1, 2018, to October 31, 2019. Thirty eligible patients were recruited, with 15 assigned to undergo single-incision laparoscopic cholecystectomy (SILC - Group A) and 15 assigned to undergo four-port laparoscopic cholecystectomy (Group B). Results: The study comprised patients aged between 20 and 60 years, with mean ages of 41.9 years for Group A and 40.3 years for Group B. Substantial variances were noted between the two groups concerning surgery duration, conversion rates, postoperative pain scores, and hospital stay. Conclusions: Based on our findings, single-incision laparoscopic cholecystectomy (SILC) cannot be deemed a standard operative procedure, mainly due to its cost implications and the necessity for specialized instruments. At present, SILC does not serve as a substitute for four-port laparoscopic cholecystectomy. Continued research and advancements are warranted to solidify SILC as a feasible alternative.

ABSTRACT

Objective To investigate the application value of transumbilical single-port total laparoscopic hysterectomy by conventional instrument without uterine-lifting in the treatment of cervical lesions.Methods We selected 60 cases of total laparoscopic hysterectomy due to cervical high-grade squamous intraepithelial lesion(HSIL)or cervical cancer stage ⅠA1 from December 2021 to June 2023.According to the patients'preference,30 cases of single-port laparoscopy through the umbilicus and 30 cases of multi-port laparoscopy were performed,both using conventional instruments without uterine-lifting.The surgical indicators of the two groups were compared.Results No conversion to open surgery occurred in both groups,and no intraoperative injuries to the urinary system,bowel,or major blood vessels occurred.As compared with the multi-port group,the single-port group had significantly reduced amount of bleeding during surgery[(54.6±20.5)ml vs.(67.5±27.0)ml,P = 0.041],earlier anal exhaust time[(27.6±8.0)h vs.(32.2±9.0)h,P =0.040],and shorter total hospitalization time[(4.4±1.5)d vs.(5.1±1.2)d,P = 0.044].There were no significant differences in uterine weight,surgical time,and postoperative complications between the two group(P>0.05).The healing of the abdominal wall puncture wounds in both groups of patients were satisfied.There were no short-term complications related to the puncture device(such as puncture wound infection and bleeding)or long-term complications(such as umbilical hernia and incisional hernia).Conclusion Transumbilical single-port total laparoscopic hysterectomy without uterine-lifting presents advantages of less intraoperative bleeding,faster postoperative recovery,and almost no scarring,with complications similar to traditional laparoscopic surgery.

ABSTRACT

Objective To investigate the clinical application value of transumbilical single-port laparoscopic ovarian cyst excision with protection of ovarian function.Methods From July 2018 to December 2019,we performed 56 cases of single-port laparoscopic ovarian cyst debulking,in which the umbilicus was incised transversely for about 2 cm and a single-port trocar puncture was placed to form an artificial pneumoperitoneum.The ultrasonic knife was used to avoid the ovarian hilum and cut the ovarian cortex on the opposite side of the ovary to ensure a good blood supply.The ovary on the affected side was fixed to facilitate blunt separation of the cyst and preserve the normal tissues of the ovary as much as possible.The 2-0 absorbable suture was applied for hemostasis and ovarian reconstruction.Results The operations were successfully completed in all the 56 cases,including bilateral ovarian cyst excision in 3 cases,salpingectomy in 3 cases,tubal mesangial cyst excision in 1 case,hysteromyomectomy in 2 cases,appendectomy in 1 case(an additional puncture hole was added due to the need for abdominal drainage after the operation),hysteroscopic resection of endometrial polyps in 1 case,and pelvic adhesion release in 1 case.The operation time was(72.0±30.0)min,and the postoperative hospitalization time was(5.0±0.6)d.No complication occurred.The 56 patients were followed up for 2-3 years,with an average of 1.5 years,with no complications,poor wound healing,or recurrence of ovarian cysts.There was no significant difference in the number of ovarian antral follicles between 6 and 12 months after surgery and before surgery[7.02±1.57 vs.7.05±1.55,P = 1.000;6.93±1.46 vs.7.05±1.55,P =1.000].There was no significant difference in ovarian stromal blood flow(P>0.05),indicating no decrease in ovarian function.Conclusion The key to protecting ovarian function is the rational selection of surgical instruments and incisions,precise performance of resection of ovarian cysts,and protection of ovarian blood supply.

ABSTRACT

Objective To investigate the application value of modified single-port laparoscopic surgery for children's unclosed processus vaginalis by using 30° electroscope,needle forceps and water injection crochet.Methods From August 2021 to December 2022,36 children with unclosed processus vaginalis were treated by modified single-port laparoscopic surgery.Instead of laparoscopy,a 30° electroscope was inserted into the abdominal cavity by the lower umbilical margin,and needle forceps were inserted into the abdominal cavity at the midpoint of the umbilical cord and pubic union.Water injection crochet with 2-0 vascular suture was inserted into the extraperitoneal space through the surface point of the internal inguinal ring.With the assistance of needle forceps,water was injected simultaneously to completely separate the spermatic vessels,vas ductus and the surrounding abdominal wall from the peritoneum around the internal ring.Without puncturing the peritoneum,the 2-0 vascular suture was wrapped around the inner ring opening in the water separation gap and led outside the body to complete the ligation.Results All the 36 cases underwent modified single-port laparoscopic surgery successfully,without conversion to open surgery.The operation time was 5-16 min(mean,9.2 min)in32 unilateral cases and9-23 min(mean,13.4 min)in 4 bilateral cases.One case was lost of follow-up,and the remaining 35 cases were followed up in outpatient clinics for 1-6 months and by telephone for 12-28 months,with a median of 20 months.There were no postoperative scrotal hematoma,testicular atrophy,or incision infection.No recurrence was found.Conclusion Modified single-port laparoscopic surgery for children's unclosed processus vaginalis is safe and feasible.

ABSTRACT

Objective:To investigate the effect of Da Vinci robot-assisted single-port plus-one laparoscopic pyeloplasty (RSPY) in children with ureteropelvic junction obstruction (UPJO).Methods:The clinical data of 13 children with UPJO diagnosed by robot-assisted single-port plus-one laparoscopic pyeloplasty in Fujian Provincial Hospital from September 2021 to August 2022 were retrospectively analyzed. The mean age of the children was 60.0 (1.3, 108.0) months. The lesions of 10 patients were on the left, and 3 were on the right. The clinical manifestations were abdominal pain in 3 cases, urinary tract infection in 2 cases, and no symptoms in 10 cases. Preoperative isotope renogram showed affected renal function (28.32±1.82)%, and bilateral renal function difference > 10% in 7 cases. Mechanical obstruction existed in 5 cases. Preoperative ultrasound showed the affected side's renal cortex thickness of (1.98 ± 0.23) cm. During the operation, a single-port multi-channel trocar was placed in the umbilicus with another single port in the epigastrium, and a robotic system was placed to explore the subperitoneal dilated renal pelvis. The renal pelvis was suspended and pulled through the abdominal wall. The visual field was exposed, and the dilated renal pelvis was incised. The dilated renal pelvis was cut, a ureteral stent was placed, and the ureteropelvic duct was anastomosed.Results:The operation of 13 cases was successfully completed, without conversion to open surgery. The operation time was 180.0(165.0, 190.2)min. The intraoperative blood loss was < 5 ml. The postoperative hospital stay was 7.0(7.0, 7.0)d, and hospitalization costs were 56.3(52.1, 56.5)thousand yuan. The ureteral stent was removed 2 months after the operation, and no obvious complications such as urinary tract infection or low back pain occurred. The median postoperative follow-up was 12 months, ranged from 6 to 18 months. Urinary color ultrasound showed that the renal cortex was (4.95±0.57) cm, which was thicker than before. Isotope renogram showed that the renal function was (38.02±1.76)%, which was higher than before. Mechanical obstruction was transformed into incomplete obstruction.Conclusions:Da Vinci robot-assisted single-port plus-one laparoscopic pyeloplasty is precise and could achieve good surgical results on the basis of the effective restoration of lesion kidney function.

ABSTRACT

@#Objective     To explore the safety and feasibility of preferential manual bronchoplasty in single-port video-assisted thoracoscopic surgery (VATS) upper lobectomy. Methods    The clinical data of 457 patients with non-small cell lung cancer who underwent single-port VATS lobectomy in the Department of Thoracic Surgery of Peking University First Hospital from March 2020 to March 2022 were retrospectively analyzed. The patients were divided into a preferential manual bronchoplasty group and a traditional single-port VATS lobectomy group with a 1 : 1 propensity score matching for further research. Results     A total of 204 patients were matched, and there were 102 patients in each group. There were 50 males and 52 females aged 62.2±10.1 years in the preferential bronchoplasty group, and 49 males and 53 females aged 61.2±10.7 years in the traditional single-port VATS group. The preferential bronchoplasty group had shorter surgical time (154.4±37.0 min vs. 221.2±68.9 min, P<0.01), less bleeding (66.5±116.9 mL vs. 288.6±754.5 mL, P=0.02), more lymph node dissection (19.8±7.5 vs. 15.2±4.7, P<0.01), and a lower conversion rate to multi-port or open surgery (2.3% vs. 13.8%, P=0.04) in left upper lobe resection. In the right upper lobe resection surgery, there was no statistical difference in postoperative results between two groups. There was no perioperative death or occurrence of bronchopleural fistula in both groups. Conclusion    Compared with traditional single-port VATS upper lobectomy, preferential bronchoplasty has similar safety and feasibility. In addition, priority bronchoplasty in left upper lobectomy has the advantages of shorter surgical time, less bleeding, more lymph node dissection, and lower conversion rate to multi-port or open surgery.

ABSTRACT

Objective:To summarize the clinical data and experience of pure single-port lumpectomy non-lipolysis breast-conserving surgery (PSLN-BCS) in patients with early-stage breast cancer.Methods:A retrospective analysis was conducted on 400 patients who underwent breast-conserving surgery for early-stage breast cancer in the Second Department of Breast Surgery at Harbin Medical University Cancer Hospital from Jan. 2022 to Jan. 2023. Patients were divided into two groups: PSLN-BCS group ( n=200) and conventional breast-conserving surgery (C-BCS) group ( n=200). The surgical time, intraoperative blood loss, postoperative drainage within three days, and short-term (3 months to 6 months after surgery) complications, including the incidence of residual fluid after drain removal and incision infection were observed. Long-term (6 months after surgery) complications, including the incidence of skin and pectoralis major muscle adhesions in the surgical area and cosmetic results after breast-conserving surgery, were also evaluated. Statistical analysis was performed using R language, and quantitative data were expressed as mean ± standard deviation ( ± s) and analyzed using t-test, while count data were analyzed using χ2 test. A p-value less than 0.05 was considered statistically significant. Results:PSLN-BCS had a longer average surgical time than C-BCS (198.341min vs 62.961min, P<0.001, 95% CI:132.028 vs 138.732). PSLN-BCS had less intraoperative bleeding (18.824 ml vs 22.627 ml, P=0.003, 95% CI: -6.294 vs -1.311) and lower postoperative drainage volume (346.157 ml vs 406.191 ml, P<0.001, 95% CI: -70.571-a-49.496). There were no significant differences in short-term postoperative complications such as subcutaneous fluid accumulation ( χ2=2.33, P=0.127) or incisional infection ( χ2=0.14, P=0.708) between the two groups. The incidence of skin and muscle adhesions in the surgical area was lower in patients who underwent PSLN-BCS at 6 months postoperatively ( χ2=11.58, P<0.001). Patients who received PSLN-BCS achieved better cosmetic outcomes, with a statistically significant difference ( χ2=273.00, P<0.001) compared to those who received C-BCS. Conclusion:Pure single-port lumpectomy non-lipolysis breast-conserving surgery is a safe and effective treatment option for early-stage breast cancer and can be considered as a surgical option for patients with cosmetic requirements.

ABSTRACT

Objective:To investigate the application value of single-port laparoscopic left lateral donor liver acquisition in pediatric living donor liver transplantation (PLDLT).Methods:The retrospective and descriptive study was conducted. The clinical data of the donor and recipient who were admitted to Beijing Friendship Hospital of Capital Medical University for PLDLT in January 2020 were collected. The donor was a male, aged 28 years with body mass as 62 kg, height as 174 cm and body mass index (BMI) as 20.5 kg/m 2. The recipient was the daughter of the donor, aged 1 year with body mass as 9 kg, height as 75 cm and BMI as 16.0 kg/m 2. The donor underwent single-port laparoscopic left lateral donor liver acquisition. The recipient underwent living donor liver trans-plantation by the same operation team. Observation indicators: (1) intraoperative conditions; (2) postoperative conditions; (3) follow-up. Results:(1) Intraoperative conditions. The donor under-went single-port laparoscopic left lateral donor liver acquisition successfully, with the single-port access system being placed through a transumbilical incision. The operation time, the warm ischemia time of the donor liver and volume of intraoperative blood loss were 240 minutes, 3 minutes and 40 mL, respectively, of the donor. The weight of the donor liver was 233.6 g, and the corrected graft-to-recipient body weight ratio was 2.60%. The recipient underwent living donor liver transplantation successfully. (2) Postoperative conditions. The donor began to take liquid diet at postoperative day 1, and results of laboratory examination showed that the alanine aminotransferase (ALT), aspartate aminotransferase (AST), glutamyltransferase (GGT) and total bilirubin (TBil) of the donor was 239 U/L, 116 U/L, 53 U/L and 22.57 μmol/L. The donor began to take diet with high quality proteins at postoperative day 2, and to get for out-of-bed activities moderately. The donor′s peritoneal drainage fluid was light red at postoperative day 3, and no fluid accumulation was found in the operation area after abdominal B-ultrasound examination, so the peritoneal drainage tube was removed. The donor was discharged at postoperative day 4. The liver function of the recipient recovered to normal level 2 weeks after the operation. (3) Follow-up. The donor was followed up by outpatient examination 2 weeks after discharged, and results of laboratory examination showed that the ALT, AST, GGT and TBil was 44 U/L, 25 U/L, 53 U/L and 9.22 μmol/L, respectively. Neither the donor nor the recipient had complication ≥Ⅱ grade of the Clavien-Dino classification, such as biliary fistula and vascular complication during the 6 months after operation.Conclusion:Single-port laparoscopic left lateral donor liver acquisition can be used into the PLDLT.

ABSTRACT

As the robotic assisted single port surgery arousing attention, a novel single-arm single-port micro-traumatic laparoscopic robotic surgical system is proposed in this study. From the perspective of the mechanics, joints with high rigidity and high reliability were utilized to realize the remote center of motion (RCM). Besides, the cost of consumables was reduced by adding the support of the rigid endoscope. From the perspective of the algorithm, high-precision motion control method and feedback force protection mechanism were implemented. The effectiveness of the aforementioned characteristics were verified by five clinical experiments of cholecystectomy. The results showed that the system is able to reduce the amount of bleeding, accelerate the patient recovery, reduce the infection risk and shorten the learning period. The robotic surgical system had significant clinical application value.

ABSTRACT

Introducción: En la búsqueda de nuevas y mejores alternativas quirúrgicas que permitan disminuir el trauma a la pared abdominal, ha surgido la cirugía por puerto único (PU), un procedimiento que consiste en la realización de la cirugía laparoscópica a través de una incisión única, generalmente en la cicatriz umbilical. Los resultados han sido alentadores y nuevas investigaciones al respecto son necesarias. Objetivo: Comparar la técnica quirúrgica de la apendicectomía laparoscópica por puerto único (PU) versus técnica estándar de 03 puertos (AL3P) en el tratamiento de pacientes con apendicitis aguda. Metodología: Estudio prospectivo, aleatorizado, incluyó 158 pacientes distribuidos en 2 grupos (71 PU, 89 AL3P), desde junio de 2013 a junio de 2016, comparándose variables demográficas, tiempo quirúrgico, complicaciones trans y postoperatorias, conversión, dolor postoperatorio, beneficios estéticos y satisfacción. Resultados: La edad, sexo, IMC, evolución, medicación previa, recuento leucocitario y fase de la enfermedad fue similar en ambos grupos. El tiempo operatorio promedio en PU fue de 48 min, menor que en AL3P (p˂0,001), y se evidenció disminución del mismo posterior a la curva de aprendizaje de 30 casos. No hubo conversión en PU a cirugía abierta. La tasa de complicaciones intra Y postoperatorias fue similar en ambos grupos (p=0,486 y p=0,887). La estancia hospitalaria fue menor en los pacientes de PU (p˂0,001) con mejor resultado estético (p=0,036) y mayor grado de satisfacción (p=0,047). Conclusión: La apendicectomía por PU demostró ser una técnica factible, segura y reproducible en nuestro medio(AU)


Introduction: In the search for new and better surgical alternatives to reduce the trauma to the abdominal wall, it has emerged single port surgery (SP), a procedure that involves performing laparoscopic surgery through a single incision, usually in the umbilicus. The results have been encouraging and further investigations are needed in this regard. Objective: To compare laparoscopic single port appendectomy (SP) versus standard 03 ports laparoscopic technique (AL3P) in the treatment of patients with acute appendicitis. Materials and Methods: Prospective, randomized study, included 158 patients divided into 2 groups (71 SP, 89 AL3P), from June 2013 to June 2016, comparing demographic variables, surgical time, trans and postoperative complications, conversion, postoperative pain, aesthetic benefits and satisfaction. Results: Age, sex, BMI, evolution, premedication, white blood cell count and stage of the disease was similar in both groups. Mean operative time was 48 min on the SP, lower than in AL3P (p˂0,001), and decreased following the learning curve of 30 cases. There was no conversion of SP to open surgery. The rate of intraoperative and postoperative complications was similar in both groups (p = 0.486 and p = 0.887). The hospital stay was lower in patients SP (p˂0,001), with better cosmetic outcome (p = 0.036) and greater satisfaction (p=0.047). Conclusion: SP appendectomy proved to be a feasible, safe and reproducible technique in our environment(AU)

ABSTRACT

Objective:To investigate the feasibility and safety of a novel single-port robotic surgical system with flexible 3D endoscope and deformable surgical instruments in zero ischemic partial nephrectomy.Methods:From May 2021 to October 2021, a prospective study on patients with renal tumor who plan to receive zero ischemic partial nephrectomy was conducted. Inclusion criteria included over 18 years old, body index between 18.5 to 30.0 kg/m2, American Society of Anesthesiologists Score ranged from 1 to 3 points, cooperation with the follow-up and related examinations, voluntary in participating the clinical trial and signing the informed consent. Exclusion criteria included patients with other co-existed malignant tumors or a medical history of other malignant tumors, the patients who have received the same urological surgery in the past, the patients who underwent or plan to undergo other major operations 3 months before or after the surgery, the patients with active pulmonary tuberculosis or severe systemic diseases, the patients to be considered not suitable to enroll in by the researchers. A novel single-port robotic surgical system was used to perform the surgery. The system consiststed of a remote control console, a surgical equipment cart, a four-arm operation cart and deformable robotic instruments which were reusable. The two-section deformable robotic instruments were able to bend in four directions and carried different surgical instruments such as unipolar scissors, bipolar grasping forceps and needle holders. The deformable robotic instruments entered the body through a special trocar with single hole and multi-channel, and then unfolded in a triangle. By bending instruments, surgeons could perform single-port robotic surgery without the trouble of "chopstick effect" or "reverse direction" . Four cases of single-port partial nephrectomy were carried out. Under general anesthesia, the patients were taken the lateral recumbent position, with elevated waist and lowered head and feet. A 3-4 cm incision was taken layer by layer along the lateral edge of the rectus abdominis at the umbilicus level. A special 2.5 cm robotic trocar was set into the cavity, and a high-definition 3D laparoscopic lens and a snake shaped mechanical arm were then put into the abdominal cavity through the trocar. All operations were performed by transperitoneal approach with an auxiliary port through the same or a different skin incision if necessary. Tumor resection and renal reconstruction were performed by the way of zero ischemia. The perioperative parameters such as tumor size, operation time, intraoperative bleeding and postoperative complications were analyzed.Results:Four patients were involved, including 2 males and 2 females, with 2 of them having a history of hypertension. The ECOG scores were all 0, and KPS score was 100 in 3 cases and 90 in 1 case. Preoperative mean serum creatinine was (76.8±18.8)μmol/L (range 70-104 μmol/L). The tumors were located on the left in 3 cases and on the right in 1 case. The diameter of the tumor ranged from 1.1 to 2.8 cm, with the TNM classification of T 1a. The R. E.N.A.L. scores were 4a, 7p, 6p and 4P respectively. The first operation was performed by pure single-port surgery, and the other 3 cases were performed with the help of an auxiliary port to ensure the safety .The operation time ranged from 155 min to 210 min, and the intraoperative bleeding ranged from 20 ml to 170 ml. Postoperative pathology showed 2 cases of renal clear cell carcinoma with negative margin and 2 cases of angiomyolipoma. No severe complications, such as bleeding or urinary leakage, were observed during the perioperative period, and the change of serum creatinine was insignificant before discharge and before operation( P=0.24). Conclusions:A robotic single-port partial nephrectomy can be successfully carried out by using this novel single-port robotic surgical system with flexible 3D endoscope and deformable surgical instruments.

ABSTRACT

Objective:To evaluate the effectiveness of pigtail catheter applying in single port video assistant thoracic surgery(VATS) for pulmonary tumor.Methods:A total of 441 patients undergoing single port VATS were obtained in this study. The patients were divided into chest-tube group and pigtail-catheter group. We used propensity score matching to match the patients 1∶1 and the clinical factors of the two groups were compared.Results:There were 143 patients in each group successfully matched by propensity score matching. The total drainage of 3 days after operation of pigtail-catheter group was significantly more than chest-tube group(375.49 ml vs. 285.03 ml, P<0.001). The pleural effusion on CT scan two weeks after surgery of pigtail-catheter group was significantly less than chest-tube group(131.77 ml vs. 178.84 ml, P=0.032). There was no significant difference between the two groups for the pain score, drainage days and inpatient days. Conclusion:Pigtail catheter can effectively improve the drainage of single port VATS, and there was no influence for the advantage of the surgery.
