OBJECTIVE

The aim of this study was to determine the different attitudes and perception of obstetrics and gynecology residents on laparoscopic skills training.

A cross-sectional research was conducted in a tertiary hospital’s Department of Obstetrics and Gynecology using a survey questionnaire. The respondents were resident physician trainees using population sampling. An approval to use the survey questionnaire from its developer was obtained. Descriptive statistics was used for analysis of the demographic profile. Pearson product moment correlation was used to determine correlation between expectancy-value constructs, simulation use and surgical experience.

The average hours the residents spent in simulation laparoscopic exercises was 11 h in the last 12 months and at least 1 h per week with supervision (76%). The reasons for using laparoscopic simulation include skill development (94%), proximity to the simulation lab (90%), free time (85%), recommendation of attending surgeon (84%), and requirement for rotation (84%). Among the expectant value constructs, only intrinsic interest utility value (r = −0.390) showed statistical correlation suggesting a weak negative correlation with simulation use. Hours of simulation use were significantly negatively correlated with self-efficacy for learning skills required to become proficient at minimally invasive surgery (MIS) (r = −0.390) and self-efficacy for learning sufficient MIS skills to perform procedures safely (r = −0.351).

The residents were motivated to do well and had greater self-belief and enjoyed performing and mastering the laparoscopic skills training. The residents’ perception revealed that there was an improvement in their MIS skills with the laparoscopic simulation exercises in the short time they spent in the simulation. Despite the residents’ positive attitude and perceptions, voluntary participation was limited. The most commonly cited barriers to the access of the surgical knowledge improvement laboratory and laparoscopy simulation unit were the lack of time due to the workload, conflicting schedules, and COVID-19 pandemic restrictions. Supervision of the residents is of great importance to provide guidance and motivation to the residents in improving their technical skills and performance in the operating room.

INTRODUCTION

Splenic Abscess is an ongoing infectious process with pus accumulation specifically at the spleen, this is associated with a high mortality rate with studies showing 16.6% among those diagnosed, with risk factors mainly present are among immunocompromised state. Among the immunocompetent population, an incidence of 0.14-0.70% were documented. 13 The etiology for this may include hematogenous or contiguous spread of infection as a pathophysiology, with bacterial seeding at the site. Detection of this is through ultrasound or CT scan, with a goal of identify a complex or a simple abscess. Therapeutics lie in choosing splenectomy, placing the patient in an immunocompromised state despite being at a young age against the conservative percutaneous drainage on top of the maximized antibiotic use. A recent meta-analysis showed a mortality rate of 12% among patients with splenectomy and a complication rate of 26%, however the percutaneous drainage had a mortality of 8% and a complication rate of 10% 14 This highlights the clinical awareness and decision among patients with splenic abscess.

Presenting a case of 37-year-old female who came in with left upper quadrant pain. This patient had undergone laparoscopic cholecystectomy 6 months prior to admission with an unremarkable outcome. An onset of left upper quadrant pain was noted 3 months prior to admission and was initially conservatively managed with unrecalled antibiotics. Persistence of this prompted further work up where ultrasound revealed an abscess in the spleen and was then admitted for broad spectrum antibiotics, namely piperacillin-tazobactam and further imaging. CT scan of whole abdomen with contrast was then done which revealed splenomegaly with rim enhancing near fluid attenuating lesions in the mid to inferior pole. The complexity of the abscess prompted the decision for splenectomy, the gold standard for treatment for splenic abscess. Patient had tested negative for HIV.

Splenic abscess is a rare condition, usually presenting with fever and left upper quadrant pain, the patient however did not present with fever despite a complex abscess. Splenic abscess is associated with a high mortality rate. A wide array of differentials is considered in patients with left upper quadrant pain and laboratories are directed into investigating the structural cause for left upper quadrant pain as the spleen has many adjacent organs which may present similarly. The decision to choose splenectomy and percutaneous abscess determines survivability of infection as splenectomy places patient in an immunocompromised state, thus early recognition of splenic abscess, and feasibility of percutaneous drainage is vital to the out-hospital outcome for the patient. Among immunocompetent individuals, given the lower mortality and lower complication rates, it may be ideal to combine both medical and minimally invasive procedures and a rise in complication may then warrant splenectomy.

OBJECTIVE: To compare the accuracy and effectiveness of orthopaedic robot-assisted minimally invasive surgery versus open surgery for limb osteoid osteoma. METHODS: A clinical data of 36 patients with limb osteoid osteomas admitted between June 2016 and June 2023 was retrospectively analyzed. Among them, 16 patients underwent orthopaedic robot-assisted minimally invasive surgery (robot-assisted surgery group), and 20 patients underwent tumor resection after lotcated by C-arm X-ray fluoroscopy (open surgery group). There was no significant difference between the two groups in the gender, age, lesion site, tumor nidus diameter, and preoperative pain visual analogue scale (VAS) scores ( P>0.05). The operation time, lesion resection time, intraoperative blood loss, intraoperative fluoroscopy frequency, lesion resection accuracy, and postoperative analgesic use frequency were recorded and compared between the two groups. The VAS scores for pain severity were compared preoperatively and at 3 days and 3 months postoperatively. RESULTS: Compared with the open surgery group, the robot-assisted surgery group had a longer operation time, less intraoperative blood loss, less fluoroscopy frequency, less postoperative analgesic use frequency, and higher lesion resection accuracy ( P<0.05). There was no significant difference in lesion resection time ( P>0.05). All patients were followed up after surgery, with a follow-up period of 3-24 months (median, 12 months) in the two groups. No postoperative complication such as wound infection or fracture occurred in either group during follow-up. No tumor recurrence was observed during follow-up. The VAS scores significantly improved in both groups at 3 days and 3 months after surgery when compared with preoperative value ( P<0.05). The VAS score at 3 days after surgery was significantly lower in robot-assisted surgery group than that in open surgery group ( P<0.05). However, there was no significant difference in VAS scores at 3 months between the two groups ( P>0.05). CONCLUSION Compared with open surgery, robot-assisted resection of limb osteoid osteomas has longer operation time, but the accuracy of lesion resection improve, intraoperative blood loss reduce, and early postoperative pain is lighter. It has the advantages of precision and minimally invasive surgery.

This is a case of a 35-year-old Gravida 5 Para 5 (5005) who underwent curettage for retained placental fragments after delivering her fifth child. Within 16-month postpartum, the patient had nonspecific occasional abdominal pain and oligomenorrhea. Imaging studies revealed a uterine defect with a bowel segment passing through. A referral to a tertiary-level hospital was made. Hysteroscopy was attempted; however, an obliterated cervical canal was encountered. Laparoscopy revealed a 10 cm ileal segment completely herniating into a 2.5 cm uterine defect at the posterior uterine wall. Laparoscopic enterolysis followed by hysterectomy, extracorporeal resection, and anastomosis of the involved ileal segment was performed. This is an uncommon case of an iatrogenic uterine perforation following curettage after a term pregnancy. Its unique clinical presentation and intraoperative findings resulted in an equally unique array of surgical approach.

OBJECTIVE: To review the application and progress of different minimally invasive spinal decompression in the treatment of lumbar spinal stenosis (LSS). METHODS: The domestic and foreign literature on the application of different minimally invasive spinal decompression in the treatment of LSS was extensively reviewed, and the advantages, disadvantages, and complications of different surgical methods were summarized. RESULTS: At present, minimally invasive spinal decompression mainly includes microscopic bilateral decompression, microendoscopic decompression, percutaneous endoscopic lumbar decompression, unilateral biportal endoscopy, and so on. Compared with traditional open surgery, different minimally invasive spinal decompression techniques can reduce the operation time, intraoperative blood loss, and postoperative pain of patients, thereby reducing hospital stay and saving treatment costs. CONCLUSION The indications of different minimally invasive spinal decompression are different, but there are certain advantages and disadvantages. When patients have clear surgical indications, individualized treatment plans should be formulated according to the symptoms and signs of patients, combined with imaging manifestations.

OBJECTIVE: To compare the short-term clinical efficacy and radiologic differences between oblique lateral interbody fusion(OLIF) and minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) for degenerative lumbar spondylolisthesis. METHODS: A retrospective analysis was performed on 58 patients with lumbar spondylolisthesis treated with OLIF or MIS-TLIF from April 2019 to October 2020. Among them, 28 patients were treated with OLIF (OLIF group), including 15 males and 13 females aged 47 to 84 years old with an average age of (63.00±9.38) years. The other 30 patients were treated with MIS-TLIF(MIS-TLIF group), including 17 males and 13 females aged 43 to 78 years old with an average age of (61.13±11.10) years. General conditions, including operation time, intraoperative blood loss, postoperative drainage, complications, lying in bed, and hospitalization time were recorded in both groups. Radiological characteristics, including intervertebral disc height (DH), intervertebral foramen height (FH), and lumbar lordosis angle (LLA), were compared between two groups. The visual analogue scale (VAS) and Oswestry disability index (ODI) were used to evaluate the clinical effect. RESULTS: The operation time, intraoperative blood loss, postoperative drainage, lying in bed, and hospitalization time in OLIF group were significantly less than those in the MIS-TLIF group (P<0.05). The intervertebral disc height and intervertebral foramen height were significantly improved in both groups after the operation (P<0.05). The lumbar lordosis angle in OLIF group was significantly improved compared to before the operation(P<0.05), but there was no significant difference in the MIS-TLIF group before and after operation(P>0.05). Postoperative intervertebral disc height, intervertebral foramen height, and lumbar lordosis were better in the OLIF group than in the MIS-TLIF group (P<0.05). The VAS and ODI of the OLIF group were lower than those of the MIS-TLIF group within 1 week and 1 month after the operation (P<0.05), and there were no significant differences in VAS and ODI at 3 and 6 months after the operation between the two groups(P>0.05). In the OLIF group, 1 case had paresthesia of the left lower extremity with flexion-hip weakness and 1 case had a collapse of the endplate after the operation;in the MIS-TLIF group, 2 cases had radiation pain of lower extremities after decompression. CONCLUSION Compared with MIS-TLIF, OLIF results in less operative trauma, faster recovery, and better imaging performance after lumbar spine surgery.

OBJECTIVE: To compare the efficacy and muscle injury imaging between oblique lateral lumbar interbody fusion (OLIF) and transforaminal lumbar interbody fusion (TLIF) in the treatment of single-segment degenerative lumbar spinal stenosis. METHODS: The clinical data of 60 patients with single-segment degenerative lumbar spinal stenosis who underwent surgical treatment from January 2018 to October 2019 was retrospectively analyzed. The patients were divided into OLIF groups and TLIF group according to different surgical methods. The 30 patients in the OLIF group were treated with OLIF plus posterior intermuscular screw rod internal fixation. There were 13 males and 17 females, aged from 52 to 74 years old with an average of (62.6±8.3) years old. And 30 patients in the TLIF group were treated with TLIF via the left approach. There were 14 males and 16 females, aged from 50 to 81 years old with an average of (61.7±10.4) years old. General data including operative time, intraoperative blood loss, postoperative drainage volume, and complications were recorded for both groups. Radiologic data including disc height (DH), the left psoas major muscle, multifidus muscle, longissimus muscle area, T2-weighted image hyperintensity changes and interbody fusion or nonfusion were observed. Laboratory parameters including creatine kinase (CK) values on postoperative 1st and 5th days were analyzed. Visual analogue scale(VAS) and Oswestry disability index(ODI) were used to assess clinical efficacy. RESULTS: There was no significant difference in the operative time between two groups(P>0.05). The OLIF group had significantly less intraoperative blood loss and postoperative drainage volume compared to the TLIF group(P<0.01). The OLIF group also had DH better recovery compared to the TLIF group (P<0.05). There were no significant differences in left psoas major muscle area and the hyperintensity degree before and after the operation in the OLIF group (P>0.05). Postoperativly, the area of the left multifidus muscle and longissimus muscle, as well as the mean of the left multifidus muscle and longissimus muscle in the OLIF group, were lower than those in the TLIF group (P<0.05) .On the 1st day and the 5th day after operation, CK level in the OLIF group was lower than that in the TLIF group(P<0.05). On the 3rd day after operation, the VAS of low back pain and leg pain in the OLIF group were lower than those in the TLIF group (P<0.05). There were no significant differences in the ODI of postoperative 12 months, low back and leg pain VAS at 3, 6, 12 months between the two groups(P>0.05). In the OLIF group, 1 case of left lower extremity skin temperature increased after the operation, and the sympathetic chain was considered to be injured during the operation, and 2 cases of left thigh anterior numbness occurred, which was considered to be related to psoas major muscle stretch, resulting in a complication rate of 10% (3/30). In the TLIF group, one patient had limited ankle dorsiflexion, which was related to nerve root traction, two patients had cerebrospinal fluid leakage, and the dural sac was torn during the operation, and one patient had incision fat liquefaction, which was related to paraspinal muscle dissection injury, resulting in a complication rate of 13% (4/30). All patients achieved interbody fusion without cage collapse during the 6- month follow-up. CONCLUSION Both OLIF and TLIF are effective in the treatment of single-segment degenerative lumbar spinal stenosis. However, OLIF surgery has obviously advantages, including less intraoperative blood loss, less postoperative pain, and good recovery of intervertebral space height. From the changes in laboratory indexes of CK and the comparison of the left psoas major muscle, multifidus muscle, longissimus muscle area, and high signal intensity of T2 image on imaging, it can be seen that the degree of muscle damage and interference of OLIF surgery is lower than that of TLIF.

OBJECTIVE: To investigate possible causes and preventive measures for asymptomatic pain in the limbs after minimally invasive transforaminal lumbar interbody fusion(MIS-TLIF). METHODS: Clinical data from 50 patients with lumbar degenerative disease who underwent MIS-TLIF between January 2019 and September 2020 were retrospectively analyzed. The group included 29 males and 21 females aged from 33 to 72 years old, with an average age of (65.3±7.13) years. Twenty-two patients underwent unilateral decompression, and 28 underwent bilateral decompression. The side(ipsilateral or contralateral) and site(low back, hip, or leg) of the pain were recorded before surgery, 3 days after surgery, and 3 months after surgery. The pain degree was evaluated using the visual analogue scale(VAS) at each time point. The patients were further grouped based on whether contralateral pain occurred postoperatively (8 cases in the contralateral pain group and 42 in the no contralateral pain group), and the causes and preventive measures of pain were analyzed. RESULTS: All surgeries were successful, and the patients were followed up for at least 3 months. Preoperative pain on the symptomatic side improved significantly, with the VAS score decreasing from (7.00±1.79) points preoperatively to (3.38±1.32) points at 3 days postoperatively and (3.98±1.17) points at 3 months postoperatively. Postoperative asymptomatic side pain (contralateral pain) occurred in 8 patients within 3 days after surgery, accounting for 16% (8/50) of the group. The sites of contralateral pain included the lumbar area (1 case), hip(6 cases), and leg (1 case). The contralateral pain was significantly relieved 3 months after surgery. CONCLUSION More cases of contralateral limb pain occur after unilateral decompression MIS-TLIF, and the reason may include contralateral foramen stenosis, compression of medial branches, and other factors. To reduce this complication, the following procedures are recommended: restoring intervertebral height, inserting a transverse cage, and withdrawing screws minimally.
