Laparoscopic Ligation of the Inferior Mesenteric Artery: A Systematic Review of an Emerging Trend for Addressing Type II Endoleak Following Endovascular Aortic Aneurysm Repair.

Background/Objectives: this systematic review aims to explore the efficacy and safety of the laparoscopic ligation of the inferior mesenteric artery (IMA) as an emerging trend for addressing a type II endoleak following endovascular aortic aneurysm repair (EVAR). Methods: A comprehensive literature search was conducted across several databases including Medline, Scopus, and the Cochrane Central Register of Controlled Trials, adhering to the PRISMA guidelines. The search focused on articles reporting on the laparoscopic ligation of the IMA for the treatment of a type II endoleak post-EVAR. Data were extracted regarding study characteristics, patient demographics, technical success rates, postoperative outcomes, and follow-up results. Results: Our analysis included ten case studies and two retrospective cohort studies, comprising a total of 26 patients who underwent a laparoscopic ligation of the IMA between 2000 and 2023. The mean age of the cohort was 72.3 years, with a male predominance (92.3%). The mean AAA diameter at the time of intervention was 69.7 mm. The technique demonstrated a high technical success rate of 92.3%, with a mean procedure time of 118.4 min and minimal blood loss. The average follow-up duration was 19.9 months, with 73% of patients experiencing regression of the aneurysmal sac, and no reports of an IMA-related type II endoleak during the follow-up period. Conclusions: The laparoscopic ligation of the IMA for a type II endoleak following EVAR presents a promising, minimally invasive alternative with high technical success rates and favorable postoperative outcomes. Despite its potential advantages, including reduced contrast agent use and radiation exposure, its application remains limited to specialized centers. The findings suggest the need for further research in larger prospective studies to validate the effectiveness of this procedure and potentially broaden its clinical adoption.

Surgical Removal of a Huge Common Bile Duct Stone.

A 65-year-old woman was diagnosed with an 8 cm large common bile duct stone and multiple stones in both intrahepatic ducts because of abnormal liver function tests. After a multidisciplinary approach, surgical removal was considered, and primary closure after laparoscopic removal of the common bile duct stone was performed. The patient recovered without complications and was discharged on the fourth postoperative day. Endoscopic removal of common bile duct stones is the standard treatment, but surgical removal through laparoscopic common bile duct exploration is also a safe and effective treatment method for such huge gallstones.

Comparative outcomes and prognostic indicators in adrenalectomy for adrenal metastasis.

PURPOSE: The indications for adrenalectomy and feasibility of laparoscopic adrenalectomy for adrenal metastasis are controversial. This study aimed to compare the surgical outcomes between open adrenalectomy (OA) and laparoscopic adrenalectomy (LA) and to evaluate the prognostic factors for oncological outcomes of adrenal metastasis. MATERIALS AND METHODS: We conducted a retrospective chart review of 141 consecutive patients who underwent adrenalectomy for adrenal metastasis at Seoul National University Hospital from April 2005 to February 2021. Surgical and oncological outcomes were compared between OA and LA. RESULTS: OA was performed in 95 (67.4%) patients, and 46 (32.6%) patients underwent LA. Among the patients who underwent adrenalectomy without adjacent organ resection for adrenal tumors less than 8 cm, LA was associated with a shorter operation time (100.1 ± 48.8 vs. 158.6 ± 81.2, P = 0.001), less blood loss (94.8 ± 93.8 vs. 566.8 ± 1156.0, P = 0.034), and a shorter hospital stay (3.7 ± 1.3 vs. 6.9 ± 5.8, P = 0.003). For locoregional recurrence-free survival (LRRFS), on multivariate analysis, a positive pathological margin (hazard ratio [HR]: 5.777, P = 0.002), disease activity at the primary site (HR: 6.497, P = 0.005), other metastases (HR: 4.154, P = 0.015), and a relatively larger tumor size (HR: 1.198, P = 0.018) were significantly associated with poor LRRFS. Multivariate analysis indicated that metachronous metastasis (HR: 0.51, P = 0.032) was associated with a longer overall survival (OS), whereas a positive pathological margin (HR: 2.40, P = 0.017), metastases to other organs (HR: 2.08, P = 0.025), and a relatively larger tumor size (HR: 1.11, P = 0.046) were associated with a shorter OS. CONCLUSIONS: LA is a feasible treatment option for adrenal metastasis in selected patients. The pathological margin, metastases to other organs, and tumor size should be considered in adrenalectomy for adrenal metastasis.

Selective hanging maneuver and rubber band retraction technique for pure laparoscopic donor right hepatectomy.

BACKGROUND: Pure laparoscopic donor hepatectomy (PLDH) is an increasingly performed procedure despite its technical difficulties. This study introduced a selective liver parenchymal hanging maneuver and rubber band retraction technique for PLDH. METHODS: We retrospectively reviewed perioperative data from 58 patients who underwent donor right hepatectomy (including right extended) between March 2009 and February 2021. Eighteen patients underwent open donor right hepatectomy (ODRH) and 38 patients underwent pure laparoscopic donor right hepatectomy (PLDRH). RESULTS: All PLDRH donors underwent the procedure without the need for open conversion. The median PLDRH operative time was 396.84 ± 72.459 min, the median PLDRH intraoperative bleeding amount was 496.05 ± 272.591 ml, and the warm ischemic time was 8.77 ± 3.062 min. Compared to ODRH, laparoscopic surgery showed further advantages in terms of postoperative hospital stay (10.94 ± 4.036 days vs. 8.03 ± 2.646 days, respectively, P = 0.01) and estimated blood loss (676.67 ± 321.046 ml vs. 496.05 ± 272.591 ml, respectively, P = 0.033). CONCLUSIONS: The selective liver parenchymal hanging maneuver and rubber band retraction technique is a simple and effective pure laparoscopic procedure for donor hepatectomy. Our results demonstrate the safety and feasibility of this technique.

A novel laparoscopic inguinal hernia repair technique: single-port lateral non-abdominal pre-peritoneal approach.

PURPOSE: Open and endoscopic techniques have been described for the treatment of inguinal hernia, but the gold standard treatment method is yet to be defined. Recurrence rates after inguinal hernia surgery vary between 10 and 15%, and chronic pain is seen in 10-12% of patients. This study aimed to introduce a new surgical technique called lateral non-abdominal pre-peritoneal repair for inguinal hernia surgery. METHODS: We recorded the data of patients' age, gender, body mass index (BMI), prior hernia surgery, hernia side, type of hernia, postoperative complications, pain scores according to the numeric pain scale, and analgesic consumption. We performed a nearly 2 cm incision from approximately 2 cm medial and superior of the anterior superior iliac spine, then separated the peritoneum from the transverse abdominal muscle by blunt dissection, and perform the surgery by a single-port device. RESULTS: Seventeen inguinal hernias were repaired with the new technique in 14 patients. Two of the patients were female. The median age was 59, and the mean BMI was 26.8 kg/m2. The median hospital stays and time passed since the surgery was 1 day and 72 days, respectively. The mean operative time was 64 ± 29 min. The median tramadol consumption was 100 mg, and the mean paracetamol consumption was 1143 mg. The median pain score on POD 1 and current pain score was 4 and 0, respectively. CONCLUSIONS: No significant complications occurred intraoperatively. We observed the pain scores were acceptable on POD 1, and excellent in postoperative follow-up. Low pain scores, low analgesic consumption, and the absence of recurrence in a newly developed procedure within the learning curve indicate that satisfactory results can be obtained.

Evolution of Minimally Invasive Adrenal Surgery at a Tertiary Care Centre in Oman.

Objectives: This study aimed to review the case records and report the outcomes of open and laparoscopic adrenalectomy (LA) cases. Methods: This retrospective study included patients who underwent adrenal surgery from January 2010 to December 2020 at Sultan Qaboos University, Muscat, Oman. Demographic details, indications, surgical approaches, intra-operative data, complications, final pathology and outcome at the last follow-up were analysed. Results: A total of 52 patients underwent 61 adrenalectomies; six patients had a bilateral procedure while three patients had to undergo revision surgery resulting in a total of 55 individual procedures. Open adrenalectomy (OA) was performed on 11 patients and 44 patients underwent LA. Most patients (n = 27) were obese with a body mass index >30. Functional adenoma was excised in 36 patients with final diagnosis of Conn's syndrome in 15, pheochromocytoma in 13 and Cushing's syndrome in nine patients. Five patients had surgery for oncological indications. Non-functional adenoma was excised in 13 patients, with a mean size of 8.9 cm (range: 4-15 cm). The mean duration of surgery was less in laparoscopic procedure compared to open (199 versus 246 minutes). The mean estimated blood loss in LA was significantly less (108 versus 450 mL; P <0.05). Out of 55 procedures, only one patient developed Clavien-Dindo grade 2 complication. Conclusion: Both LA and OA were safely performed at the researchers' institution. There is a growing trend for LA, and with experience, the duration of surgery and estimated mean blood loss are demonstrating a positive trend.

Postoperative adverse events and re-treatment among patients who have undergone laparoscopic and robotic sacrocolpopexy for pelvic organ prolapse in Japan.

OBJECTIVE: To describe and compare the postoperative adverse events and re-treatment for recurrence after laparoscopic and robotic-assisted sacrocolpopexy in Japanese patients with pelvic organ prolapse (POP). METHODS: This was a retrospective cohort study using the DeSC database, which contains claims and medical check-up data provided by DeSC Healthcare Inc., Tokyo, Japan. We identified all patients who had undergone either laparoscopic or robotic-assisted sacrocolpopexy from April 2014 to May 2021. Patient backgrounds and postoperative outcomes were compared between the laparoscopic and robotic-assisted sacrocolpopexy groups. Moreover, the composite adverse event comprising vaginal erosion, postoperative urinary incontinence, postoperative dysuria, urinary tract injury, and abdominal incisional hernia was evaluated. Re-treatment for POP recurrence included pessary use and surgery for POP was also evaluated. RESULTS: Among 28 748 patients diagnosed with POP, 409 (1.4%) had undergone laparoscopic sacrocolpopexy and 52 (0.2%) had undergone robotic-assisted sacrocolpopexy. The prevalence of postoperative adverse events was 20.8% and 13.5% in the laparoscopic and robotic-assisted sacrocolpopexy groups, respectively (P = 0.270). One patient (1.9%) underwent surgery after robotic-assisted sacrocolpopexy, and none of the patients was administered pessaries postoperatively in both groups. CONCLUSION: In Japan, postoperative outcomes after laparoscopic and robotic-assisted sacrocolpopexy are similar and comparable to those reported in western countries.

Abdominoscrotal Haematocele in an Adult and Its Successful Treatment.

Abdominoscrotal hydrocele (ASH) is a variant of hydrocele that rarely occurs in adults. ASH has two sacs, one in the scrotum and one in the abdomen connected through the inguinal canal. Abdominoscrotal haematocele is a rare complication of ASH. We report a 57-year-old male patient who presented to a tertiary care hospital in Puducherry, India, in 2019 with complaints of swelling in the scrotum for 15 years and abdominal pain for two months. Both the swellings were soft and cross fluctuation was present. Imaging confirmed the diagnosis of ASH. During a diagnostic laparoscopy, the abdominal sac was decompressed and found to have thick brownish fluid suggestive of haematocele. It was demonstrated that both sacs were connected. Due to difficulty in the dissection of the sac, the procedure was converted to an open procedure. Both the sacs were excised and Lytle's repair was done for the dilated internal ring. The patient recovered and no recurrence of any swelling in the abdomen or scrotum was found at the end of a one-year follow-up.

Transcatheter chemoembolization plus percutaneous radiofrequency ablation versus laparoscopic radiofrequency ablation: improved outcome for inoperable hepatocellular carcinoma.

AIMS: To retrospectively compare the efficacy of transcatheter chemoembolization (TACE) plus percutaneous radiofrequency ablation (PRFA) (hereafter, TACE + PRFA) and laparoscopic radiofrequency ablation (LRFA) in the treatment of inoperable hepatocellular carcinoma (HCC). METHODS: From July 2014 to December 2017, 132 consecutive patients with inoperable HCC were treated with TACE + PRFA (n = 86) or LRFA (n = 46). Overall survival (OS) and recurrence-free survival (RFS) were analyzed using log-rank test and Cox regression analysis. Propensity score matched (PSM) analyses based on patient and tumor characteristics were also conducted. Additionally, we performed exploratory analyses to determine the effectiveness of TACE + PRFA and LRFA in clinically relevant subsets. RESULTS: The baseline characteristics of TACE + PRFA patients displayed relatively inferior liver status and a higher rate of BCLC-B disease. For unmatched patients, median OS (55.0 vs. 42.0 months; p = .019) and RFS (20.0 vs. 11.0 months; p < .001) were significantly longer in TACE + PRFA group than that in the LRFA group. After PSM, 39 matched pairs were identified. The difference in median OS (60.0 vs. 44.0 months; p = .009) and RFS (27.0 vs. 11.0 months; p < .001) between the two groups remained significant. Multivariate analysis in matched patients showed that treatment modality and response to initial treatment were significant predictors of OS and RFS, while recurrence after resection was an independent prognostic factor of OS. The benefits of TACE + PRFA were consistent across all the subgroups examined. The different treatments had shared a similar complication rate. CONCLUSIONS: Compared to LRFA, TACE + PRFA results in improved OS and RFS in patients not amenable to resection.

Same problem, different approaches: transvesical and extravesical laparoscopic vesicovaginal fistula repair-case report.

Vesicovaginal fistulas (VVaFs) are relatively uncommon in developed countries but with devastating consequences for the women suffering them. Conservative management has a low response rate. The surgical repair is a technically demanding procedure. Transvaginal, open transabdominal or laparoscopic (pure or robot-assisted) approaches have been described with similar post-operative results. We report two real-life cases of VVaF after surgery of benign gynaecological conditions, both presenting with continuous urinary incontinence and repaired with laparoscopic surgery. The first case had a simple tract above the trigone and was managed with an extravesical approach. The second is a complex case with multiple fistulous tracts that required a transabdominal-transvesical approach (modified O'Connor technique). Both patients have their fistula closed and are continent after surgery with a mean follow-up of 9 months. Given the lack on evidence for the selection of the best approach, it is important to report the outcomes with the different surgical techniques in both simple and complex fistulae. A pre-operative exhaustive study of the location and number of fistulous tracts is essential, as well as selecting the technique which best allows tissue dissection and tension-free suture to get a successful closure. Therefore, knowledge of several procedures and approaches is mandatory when dealing with this disorder.

Single-incision laparoscopic surgery using the glove technique with improved maneuverability achieved through fulcrum creation via a simple ring technique.

INTRODUCTION: Single-incision laparoscopic surgery (SILS) is widely used in many surgical procedures in various specialties. Among the access methods used in SILS, the glove technique, which is typically similar to the multi-trocar approach, is simple, convenient, and inexpensive. However, given the absence of a fulcrum supporting the endoscopic surgical forceps, the technique is less advantageous than methods using commercially available access devices because of the poor maneuverability of the forceps. MATERIALS AND SURGICAL TECHNIQUE: By creating a fulcrum as a support to use with existing surgical forceps in the glove technique, we designed and used a novel method known as the "ring technique." This technique aimed to improve the maneuverability of endoscopic surgical forceps. DISCUSSION: Placing a fulcrum resulted in the improvement of the forceps' maneuverability, which helped to ameliorate a weakness of the glove technique. The ring technique could be a useful option as a method of access in SILS.

Recurrence of common bile duct stones following laparoscopic common bile duct exploration: a multicenter study.

BACKGROUND: Recurrence of common bile duct stone (CBDS) is not common after laparoscopic common bile duct exploration (LCBDE). This study aimed to investigate the risk factors of recurrence of CBDS after LCBDE. METHODS: Patients who underwent LCBDE between January 2001 and December 2018 in four teaching hospitals of The Catholic University of Korea were included. The operation, fluoroscopy, and endoscopic retrograde cholangiopancreatography records were investigated retrospectively. The primary outcome of this study was the independent risk factors for recurrence of CBDS. RESULTS: A total of 230 patients were included in this study. Thirty-one patients had recurrence of CBDS. In univariate analysis, CBDS size (>9 mm) (P = 0.003), multiple stones (≥2) (P = 0.031), stone size (≥1.5 cm) (P = 0.041), CBD diameter (≥12 mm) (P = 0.005), CBD dilatation (≥10 mm) (P = 0.02), prior history of laparoscopic cholecystectomy (P = 0.002) were associated with recurrence. After multivariable logistic regression, CBDS size (>9 mm) (OR 4.67, 95% CI 1.35-16.18, P = 0.011), CBD dilatation (≥10 mm) (OR 5.66, 95% CI 1.47-21.82, P = 0.012), and prior history of laparoscopic cholecystectomy (AOR 3. 90, 95% CI 1.34-11.37, P = 0.013) were associated with recurrence. CONCLUSIONS: Stone size >9 mm, CBD diameter ≥10 mm, and prior history of laparoscopic cholecystectomy were risk factors for recurrence of CBDS after LCBDE.

Laparoscopic modified Y-V plasty for recurrent bladder outlet obstruction induced by operation of benign prostatic hyperplasia / 中华泌尿外科杂志

Objective To investigate the clinical effect of laparoscopic modified bladder neck Y-V plasty in the treatment of recurrent bladder outlet obstruction after surgery for prostatic hyperplasia.Methods Seventeen patients with recurrent bladder outlet obstruction after prostatic hyperplasia operation from May 2017 to January 2019 was treated by laparoscopic bladder neck Y-V plasty,with the median age of 71 years old (65-81 years).All had a history of repeated urination obstruction and urinary tract infection,and experienced at least 2 times transurethral stenosis incision,resection or repeated urethral dilatation,with 12 cases of bladder neck stenosis (type Ⅰ) and 5 cases of middle prostate stenosis (type Ⅱ).Three-port laparoscopy surgery was performed with outer-peritoneal route into the Retzius Gap.After revealing the bladder and prostate junction,the "Y" incision of the bladder and stenosis of the prostate urethra was firstly performed,and inverted symmetrical "V" shape suture was performed with two 3-0 Stratifix suture for two layers,including the 1th layer suture of mucosal and inner muscle layer,and the 2nd layer suture of the outer muscle and the serous layer.F22 silicone catheter was indwelled for 2 weeks postoperatively.Urinary flow rate and bladder urethral examination were perfrmed to evaluate the effect of surgery 2 weeks and 3 months after the operation respectively.Results Seventeen operations were completed successfully,with the median operation time of 100 minutes (30-100 minutes),the median operation blood loss of 50 ml (20-100 ml),and the median hospital stay of 5 days (1-7 days).The patient had unobstructed voiding after removing the urinary catheter 2 weeks postoperatively,and had no urinary incontinence.Postoperative median follow-up was 7 months (3-17 months) and no stenosis of the urethra was detected.Conclusions Laparoscopic modified bladder neck Y-V Plasty has the advantages of high success rate,low recurrence rate and minimally invasiveness in the treatment of recurrent bladder outlet obstruction after prostatic hyperplasia surgery,which is worthy of clinical application.

Advantages of Laparoscopic Radiofrequency Ablation Over Percutaneous Radiofrequency Ablation in Hepatocellular Carcinoma.

BACKGROUND: Inoperable hepatocellular carcinoma (HCC) can be treated with laparoscopic radiofrequency ablation (LRFA), which is generally a more accurate and accessible procedure than percutaneous RFA (PRFA). However, few studies have compared survival outcomes between LRFA and PRFA in patients with HCC. AIMS: This study aimed to compare the efficacy of LRFA and PRFA for HCC treatment. METHODS: Patients who underwent PRFA or LRFA as an initial treatment modality between April 2005 and April 2016 were enrolled in this study. The overall and recurrence-free survival rates were examined for each patient. Additionally, propensity score matching was performed for both groups. RESULTS: The baseline characteristics of patients in the PRFA and LRFA groups showed several minor differences. Multivariate analysis showed that the RFA method was not a critical determinant of recurrence-free or overall survival (p = 0.069 and p = 0.406). Among patients who underwent RFA as the initial treatment modality, there was no significant effect between either RFA procedures on survival. After propensity score matching, univariate analysis showed a significant difference in overall survival between PRFA and LRFA (p = 0.031). Multivariate analysis showed that LRFA is a strong factor that contributed to an improved overall survival in HCC patients (hazard ratio 0.108, p = 0.040). Furthermore, our data showed that LRFA was able to limit multiple intrahepatic recurrences, as well as prevent marginal recurrence. CONCLUSIONS: LRFA appears to be superior to PRFA in terms of survival. LRFA may help reduce mortality in HCC patients.

Robotic versus laparoscopic left lateral sectionectomy of liver.

BACKGROUND: A few studies have reported only short-term outcomes of various robotic and laparoscopic liver resection types; however, published data in left lateral sectionectomy (LLS) have been limited. The aim of this study was to compare the long- and short-term outcomes of robotic and laparoscopic LLS. METHODS: We retrospectively compared demographic and perioperative data as well as postoperative outcomes of robotic (n = 12) and laparoscopic (n = 31) LLS performed between May 2007 and July 2013. Resection indications included malignant tumors (n = 31) and benign lesions (n = 12) including intrahepatic duct (IHD) stones (n = 9). RESULTS: There were no significant differences in perioperative outcomes of estimated blood loss, major complications, or lengths of stay, but operating time was longer in robotic than in laparoscopic LLS (391 vs. 196 min, respectively) and the operation time for IHD stones did not differ between groups (435 vs. 405 min, respectively; p = 0.190). Disease-free (p = 0.463) and overall (p = 0.484) survival of patients with malignancy did not differ between groups. The 2- and 5-year disease-free survival rates were 63.2 and 36.5 %, respectively. However, robotic LLS costs were significantly higher than laparoscopic LLS costs ($8183 vs. $5190, respectively; p = 0.009). CONCLUSIONS: Robotic LLS was comparable to laparoscopic LLS in surgical outcomes and oncologic integrity during the learning curve. Although robotic LLS was more expensive and time intensive, it might be a good option for difficult indications such as IHD stones.

Learning curve patterns generated by a training method for laparoscopic small bowel anastomosis.

BACKGROUND: The identification of developmental curve patterns generated by a simulation-based educational method and the variables that can accelerate the learning process will result in cost-effective training. This study describes the learning curves of a simulation-based instructional design (ID) that uses ex vivo animal models to teach laparoscopic latero-lateral small bowel anastomosis. METHODS: Twenty general surgery residents were evaluated on their performance of laparoscopic latero-lateral jejuno-jejunal anastomoses (JJA) and gastro-jejunal anastomoses (GJA), using swine small bowel and stomach on an endotrainer. The ID included the following steps: (1) provision of references and videos demonstrating the surgical technique, (2) creation of an engaging context for learning, (3) critical review of the literature and video on the procedures, (4) demonstration of the critical steps, (5) hands-on practice, (6) in-action instructor's feedback, (7) quality assessment, (8) debriefing at the end of the session, and (9) deliberate and repetitive practice. Time was recorded from the beginning to the completion of the procedure, along with the presence or absence of anastomotic leaks. RESULTS: The participants needed to perform 23.8 ± 6.96 GJA (12-35) and 24.2 ± 6.96 JJA (9-43) to attain proficiency. The starting point of the learning curve was higher for the GJA than for the JJA, although the slope and plateau were parallel. Further, four types of learning curves were identified: (1) exponential, (2) rapid, (3) slow, and (4) no tendency. The type of pattern could be predicted after procedure number 8. CONCLUSIONS: These findings may help to identify the learning curve of a trainee early in the developmental process, estimate the number of sessions required to reach a performance goal, determine a trainee's readiness to practice the procedure on patients, and identify the subjects who lack the innate technical abilities. It may help motivated individuals to become reflective and self-regulated learners. Moreover, the standardization of the ID may help to measure the effectiveness of learning strategies and make comparisons with other educational strategies.

Laparoscopic vs mini-incision open appendectomy.

AIM: To compare laparoscopic vs mini-incision open appendectomy in light of recent data at our centre. METHODS: The data of patients who underwent appendectomy between January 2011 and June 2013 were collected. The data included patients' demographic data, procedure time, length of hospital stay, the need for pain medicine, postoperative visual analog scale of pain, and morbidities. Pregnant women and patients with previous lower abdominal surgery were excluded. Patients with surgery converted from laparoscopic appendectomy (LA) to mini-incision open appendectomy (MOA) were excluded. Patients were divided into two groups: LA and MOA done by the same surgeon. The patients were randomized into MOA and LA groups a computer-generated number. The diagnosis of acute appendicitis was made by the surgeon with physical examination, laboratory values, and radiological tests (abdominal ultrasound or computed tomography). All operations were performed with general anaesthesia. The postoperative vision analog scale score was recorded at postoperative hours 1, 6, 12, and 24. Patients were discharged when they tolerated normal food and passed gas and were followed up every week for three weeks as outpatients. RESULTS: Of the 243 patients, 121 (49.9%) underwent MOA, while 122 (50.1%) had laparoscopic appendectomy. There were no significant differences in operation time between the two groups (P = 0.844), whereas the visual analog scale of pain was significantly higher in the open appendectomy group at the 1(st) hour (P = 0.001), 6(th) hour (P = 0.001), and 12(th) hour (P = 0.027). The need for analgesic medication was significantly higher in the MOA group (P = 0.001). There were no differences between the two groups in terms of morbidity rate (P = 0.599). The rate of total complications was similar between the two groups (6.5% in LA vs 7.4% in OA, P = 0.599). All wound infections were treated non-surgically. Six out of seven patients with pelvic abscess were successfully treated with percutaneous drainage; one patient required surgical drainage after a failed percutaneous drainage. There were no differences in the period of hospital stay, operation time, and postoperative complication rate between the two groups. Laparoscopic appendectomy decreases the need for analgesic medications and the visual analog scale of pain. CONCLUSION: The laparoscopic appendectomy should be considered as a standard treatment for acute appendicitis. Mini-incision appendectomy is an alternative for a select group of patients.

Assessment of selected perioperative parameters in patients undergoing laparoscopic and abdominal supracervical hysterectomy.

INTRODUCTION: Subtotal hysterectomy is a method of treatment of patients with mild changes in the uterine body. Laparoscopic methods are increasingly used in surgical gynaecology. One of the limitations of laparoscopy is the proper level of operating surgeon's training, which may be assessed with the use of the learning curve. The aim of the study was to compare data regarding the perioperative period in patients who underwent subtotal hysterectomy with the two methods, and to establish a learning curve for laparoscopic subtotal hysterectomy. MATERIAL AND METHODS: One hundred and twenty-seven patients qualified for subtotal hysterectomy due to mild disturbances in the uterine body participated in the study. The study was conducted at the Clinical Department of Gynaecology and Obstetrics of Fryderyk Chopin Provincial Specialist Hospital in Rzeszów in 2012-2013. RESULTS: The time of laparoscopic subtotal hysterectomy is longer than that of the classical surgical procedure. Uterine myomas are the main indication for subtotal hysterectomy. Laparoscopic operation results in lower blood loss compared to the classical surgical method. The mean age of the patients operated due to mild changes in the uterine body is similar in both groups. Patients who are obese or have undergone Caesarean sections are more frequently qualified for the classical surgery. The study revealed a reduction in time of laparoscopic subtotal hysterectomy by ca. 31 minutes (33%). CONCLUSIONS: Laparoscopic subtotal hysterectomy is a method chosen by operating surgeons for patients with a lower perioperative risk. The period of the study made it possible to determine a learning curve for laparoscopic subtotal hysterectomy.

Laparoscopic Non-clamping Tumor Enucleation of Renal Hilum Schwannoma in a Single Kidney: A Case Report.

A 56-year-old woman underwent laparoscopic right nephrectomy due to pyonephrosis associated with right ureteral stones. Moreover, the patient developed a brain stem hemorrhage and became bedridden. At the time of nephrectomy, a renal tumor, with a size of 24 × 24 × 20 mm, was observed in the left renal hilum; the tumor did not show contrast enhancement on computed tomography. After 3 years, the tumor gradually grew to a size of 45 × 35 × 34 mm, and therefore, laparoscopic non-clamping tumor enucleation was performed. Pathological examination confirmed a diagnosis of renal schwannoma.
