Clinical effects of robot-assisted esophageal hiatal hernia repair and laparoscopic esophageal hiatal hernia repair: a retrospective comparative study

Objective: To analyze the short-term clinical effects of robot-assisted and laparoscopic repair of the hiatal hernia. Methods: The clinical data of 56 patients underwent minimally invasive hiatal hernia repair from January 2021 to January 2022 in the Department of Minimally Invasive Surgery, Hernias and Abdominal Wall Surgery, People's Hospital of Xinjiang Uygur Autonomous Region were retrospectively analyzed. There were 32 males and 24 females, aging (59.7±10.7) years (range: 28 to 75 years). All patients were divided into laparoscopy group (n=27) and robot group (n=29) according to surgical procedures. Perioperative conditions, hospital stay, and improvement in symptoms before and after surgery were compared between the two groups by the t test, Wilcoxon rank-sum test and χ2 test. Results: All surgical procedures were successfully completed, without conversion to laparotomy or change in operation mode. There were no serious complications related to the operation. The intraoperative blood loss of the robot group was less than that of the laparoscopic group (M (IQR)): (20 (110) ml vs. 40 (80) ml, Z=-4.098, P<0.01). The operation time ((111.7±33.6) minutes vs. (120.4±35.0) minutes, t=-0.943, P=0.350) and hospitalization time ((3.9±1.4) days vs. (4.7±1.9) days, t=-1.980, P=0.053) of the robot group and the laparoscopic group were similar. Follow-up for 12 months after the operation showed no postoperative complications and recurrence. The score of the health-related quality of life questionnaire for gastroesophageal reflux disease in the robot group decreased from 10.8±2.8 before the operation to 6.5±0.6 after the operation, and that in the laparoscopic group decreased from 10.6±2.1 before the operation to 6.3±0.6 after the operation. There was no difference in the influence of different surgical methods on the change in score (t=0.030,P=0.976). Conclusion: Compared with laparoscopic repair of the hiatal hernia, robot-assisted hiatal hernia repair has the advantages of less bleeding, rapid postoperative recovery and good short-term effect.

Application of an Extracorporeal-Assisted Intracorporeal Sliding Knot-Tying Technique in Minimally Invasive Surgery in Children.

Background: A retrospective study was carried out to determine the feasibility and safety of an extracorporeal-assisted intracorporeal sliding knot-tying technique in minimally invasive surgery in children. Materials and Methods: From June 2009 to December 2017, a total of 333 cases of pediatric minimally invasive surgery were performed using the extracorporeal-assisted intracorporeal sliding knot-tying technique. Polyester, polyglactin, and polydioxanone sutures were used for suturing and knotting. The average time used for knotting was recorded during the surgery. The patients were followed up for unraveled knots and recurrence of the diseases. Results: All 333 surgical procedures were performed successfully, including 152 cases of thoracoscopic diaphragmatic hernia repair, 151 cases of thoracoscopic diaphragmatic plication, 7 cases of thoracoscopic esophageal anastomosis, and 23 cases of laparoscopic esophageal hiatal hernia fundoplication. No serious complications or mortalities were observed. Twelve-month to 9-year follow-up showed that all pediatric patients recovered well and no recurrence or unraveled knots were found. Conclusions: This new knot-tying technique is safe and feasible for various minimally invasive endoscopic surgeries, especially for suturing tissues under tension, such as thoracoscopic diaphragmatic hernia repair, laparoscopic esophageal hiatal hernia repair, and fundoplication. All types of sutures can be used for this knot-tying technique. It is easy to learn and can be quickly mastered by doctors with endoscopic surgery experience.

Strangulation of the stomach and the transverse colon following laparoscopic esophageal hiatal hernia repair.

The authors present a 32-year-old male patient with incarceration of a recurrent esophageal hiatal hernia after laparoscopic repair. A life-threatening strangulation of the stomach and the transverse colon occurred within a few days after the operation. Relapse of hiatal hernias amounts to almost half of early complications characteristic for the laparoscopic approach. General recommendations regarding surgical technique as well as perioperative care have been proposed in order to decrease the risk of relapse. Also, routine contrast radiology on the first or second day following the laparoscopic operation facilitates early diagnosis of relapse of hiatal hernia with emergent reoperation. This may result in decreased morbidity and improved overall outcome of the treatment.
