Background: Mini-laparoscopy, or needlescopy, is an emerging minimally invasive technique that aims to improve on standard laparoscopy in the areas of tissue trauma, pain, and cosmesis. The objective of this study was to determine if there was a difference in functionality between 2 novel mini-laparoscopic instruments when compared to standard laparoscopic tools. Differences were assessed in a simulated surgical environment. Methods: Twenty participants (5 novices, 10 intermediate, 5 expert) were recruited for this institutional review board–approved study in a surgical simulation training center. Group A tools were assembled intracorporeally, and Group B tools were assembled extracorporeally. Using standard laparoscopic graspers, mini-laparoscopic graspers, or a combination of both, each participant performed 3 basic laparoscopic training tasks: a Peg Transfer, Rubber Band Stretch, and Tootsie Roll Unwrapping. Following each round of tasks, participants completed a survey evaluating the mini-laparoscopic graspers with respect to standard laparoscopic graspers. Data were analyzed using Kruskal-Wallis test with Dunn’s test for post hoc comparisons. Results: When comparing task times, both mini tools performed at the level of standard laparoscopic graspers in all participant groups. Group A tools were quicker to assemble and disassemble versus Group B tools. According to posttask surveys, all participant groups indicated that both sets of mini-laparoscopic graspers were comparable to the standard graspers. Conclusion: In a nonclinical setting, mini-laparoscopic instruments perform at the level of standard laparoscopic tools. Based on these results, clinical trials would be a reasonable next step in assessing feasibility and safety.

Abstract Background The quest for better patient outcomes is driving to the development of minimally invasive spine surgical techniques. There are several evidences on the use of microsurgical decompression surgery for degenerative lumbar spine stenosis; however, few of these studies compared their outcomes with the traditional laminectomy technique. Objectives The aim of our study was to compare outcomes following microsurgical decompression via unilateral laminotomy for bilateral decompression (ULBD) of the spinal canal to the standard open laminectomy for cases with lumbar spinal stenosis. Subjects and methods Cases were divided in two groups. Group (A) cases were operated by conventional full laminectomy; Group (B) cases were operated by (ULBD) technique. Results from both groups were compared regarding duration of surgery, blood loss, perioperative complication, and postoperative outcome and patient satisfaction. Results There was no statistically significant difference between both groups regarding the improvement of visual pain analogue, while improvement of neurogenic claudication outcome score was significant in group (B) than group (A). Seventy-three percent of group (A) cases and 80% of group (B) stated that surgery met their expectations and were satisfied from the outcome. Conclusion Comparing ULBD with traditional laminectomy showed the efficacy of the minimally invasive technique in obtaining good surgical outcome and patient satisfaction. There was no statistically significant difference between both groups regarding the occurrence of complications The ULBD technique was found to respect the posterior spinal integrity and musculature, accompanied with less blood loss, shorter hospital stays, and shorter recovery periods than the open laminectomy technique.

Background: Hysterectomy is the most common operation performed by gynecologist, next to caesarean section. Currently, there are three main types of hysterectomy operations in practice for benign diseases-Abdominal hysterectomy (AH), vaginal hysterectomy (VH) and Laparoscopic hysterectomy (LH). Vaginal route for non-descentuterus is an acceptable method of hysterectomy. The objective of present study was to compare the operating time, intraoperative and postoperative complications between VH and TAH in non-descent uterus. Methods: The study was conducted in the Department of Obstetrics Gynaecology for a period of 18months at Darbhanga Medical College & Hospital, Laheriasarai, Bihar. Results: Over the study period 100 patients were taken, 50 patients underwent non-descent vaginal hysterectomy andlabelled as group A and 50 patients were under went total abdominal hysterectomy and labelled as group B. It wasseen that intraoperative complications and postoperative complications were less in group A patients and operating time is also less with group A patients when compared with group B patients. Conclusions: From the present study, it was concluded that NDVH is associated with less blood loss during surgery, quicker recovery, and early mobilization, less operative and less postoperative morbidity when compared to TAH. NDVH is a less invasive technique with shorter hospital stay and faster convalescence.

Background: Surgical simulation training offers trainees the opportunity to practice surgical skills before entering the operating room. The objectives of this study were to determine the effect of simulation for learning instruments for burr hole surgery and whether this learning is translated to real instrument recognition with retention. Methods: Randomized trials of PGY1 neurosurgery residents and perioperative nurses were conducted, using PeriopSim™ for instrument recognition, as well as real instruments. Group A performed simulation tasks using PeriopSim™ prior to identifying real instruments, whereas Group B identified real instruments prior to performing simulation tasks. Nurses’ recall was assessed at seven days. Results: Sixteen residents and 100 nurses were recruited. All participants showed significant overall improvement in their scores for simulated tasks. Group A demonstrated enhanced accuracy and speed of identifying real instruments compared with Group B (p<0.001). Furthermore, knowledge recall testing at one week demonstrated retained learning, shown by 97% accuracy in instrument identification. Conclusions: Our results demonstrate that recognition of surgical instruments improves with repeated use of the PeriopSim™ platform. Instrument knowledge acquired through simulation training results in improved identification and retained recognition of real instruments.

Tissue trauma after surgery activates blood coagulation. This results in a change and in the consumption of important inhibitors.We investigated the oonoentraticn of antithrorfoin III (AT III), ∝ 1-antitrypsin (∝l-AT), ∝ 2- macrogloublin (∝ 2-M) and Cl-inactivator (Cl-INH) in the blood plasma by means ofradial iirmunodiffusicn in 16 patients before surgery, after surgery and cn the 1st, 3rd and 7th days after surgery. In 11 patients normal wound healing wasobserved (group A), while in 5 patients amplicationsoccurred (group B). AT III: Fall in concentration upto the 3rd day after surgery, then a rise in concentration. In the patients with impaired wound healing there was a particularly marked reduction in AT III cn the 3rd day.∝ 1-AT: Fall in concentration after surgery, followed by a rise in concentration. In impaired wound healing a lower mean value was determined on the 3rd day after surgery than in normal wound healing. ∝ 2-M: Fall in concentration up to the 3rd day after surgery, followed by a slight increase in concentration. No striking difference between the normal group and the group with complications. Cl-INH: Fall in concentration after surgery, followed by arise in concentration; in the patients with impaired wound healing there was adelayed rise in concentration.

Objectives: To compare open hemorrhoidectomy and Rubber Band Ligation (RBL) in the management of 2nd and 3rd degree hemorrhoids in terms post operative and hospital stay. Design: Experiential Randomized Control Trial. Setting: Department of surgery, Allied Hospital and Independent University Hospital Faisalabad. Period: Dec 2008 to May 2009. Patients & Methods: 100 consecutive patients with second and third degree hemorrhoids were randomly divided into two groups. Group A (50 patients) were operated by open hemorrhoidectomy (Milligan morgan technique) while in group B (50 patients) rubber band ligations was performed. Open hemorrhoidectomy was performed under spinal anesthesia while rubber bands were applied with local xylocaine gel using Barron’s rubber band ligator. All the three hemorrhoids were ligated in single session. Results: Average hospital stay was 24 hours in patient operated by open hemorrhoidectomy as compared to one hour in rubber band ligation. 60% patients in group A developed moderate to severe pain requiring I/V morphine derivatives while 40% developed mild pain and treated with NSAIDS. In group B only 20% patients developed moderate pain and were dealt with I/M diclofenac sodium. Eightyeight percent patients in group A and 60% patients in group B developed mild to moderate bleeding in first postoperative week, which was self limiting. 6 patients developed severe bleeding after hemorrhoidectomy requiring blood transfusion. During six month follow up, two patients (4%) of open hemorrhoidectomy and 3 patients (6%) of RBL presented with recurrence and respective procedures were repeated. Conclusions: Rubber band ligation is safe, quick, economical and effective method for the treatment of 2nd and 3rd degree hemorrhoids.

Background Diffusion-weighted imaging (DWI) offers a non-invasive technique that can reveal microscopic details about the architecture of both normal and anomalous tissues. Some studies have confirmed DWI can detect the early changes of tumors that have originated from various organs, even after treatment. Purpose To compare the usefulness of apparent diffusion coefficient (ADC) and morphologic magnetic resonance (MR) imaging for monitoring the therapeutic response of metastatic disease in lymph nodes to radiotherapy. Material and Methods Twenty-six rabbits (metastatic, n = 17; non-metastatic, n = 9) were divided into group A (metastatic, n = 10), group B (metastatic, n = 7) and group C (non-metastatic, n = 9). Groups A and C underwent irradiation, whereas group B was set as a reference. Standard MR imaging and DWI were performed before and 1, 3, and 7 days after radiotherapy for all rabbits. The lymph node volumes and ADCs were measured and evaluated with repeated measures ANOVA. The difference between group A and B was analyzed using Student's t-test. Results In all rabbits, a total of 35 lymph nodes were found, including 16 nodes in group A, 10 in group B and nine in group C. In group A, 3 and 7 days after therapy ADCs were significantly higher than pre-treatment and 1 day after therapy ( P < 0.05). For groups A and B, a significant difference of ADCs was present 7 days after therapy. A significant difference of variation of ADCs among the three groups was also present ( P < 0.001). Conclusion DWI is superior to morphological MRI in monitoring early radiation response in animal models.

Abstract Background Unlike acute Achilles tendon rupture (AATR), neglected Achilles tendon rupture (NATR) requires usually tendon grafting procedures for repair tendon defects caused by removing scar tissue. The conventional open surgery of V-Y tendon plasty and minimally invasive technique with plantar tendon transfer had been described, but the long-term efficacy between the two techniques still needs further certification. Methods Between February 1, 2008, and July 31, 2018. All of 46 patients with neglected Achilles tendon rupture, 25 patients in group A (21 males and 4 females; age, 34.28 ± 6.97 years) underwent the conventional operation of V-Y tendon plasty, and 21 patients in group B (14 males and 7 females; age, 35.29 ± 7.42 years) were treated by the minimally invasive technique. Two years follow-up was performed for the functional recovery with examinations of the Achilles tendon rupture score (ATRS), American Orthopaedic Foot and Ankle Society (AOFAS) Ankle Hind-Foot Scale Score, dorsiflexion, calf circumference, and heel raise test. Results Patient characteristics between the two groups were similar. The functional score of ATRS and AOFAS in Group B was higher than patients in group A at postoperative months 3, 6, and 12, while there is no difference at month 24. In group A, there were three patients exposed to soft tissue infections (two superficial infections and one deep infection) and one case with tendon exposure. In group B, a patient with tendon re-rupture was observed. There was no difference in dorsiflexion and calf circumference at follow-up two years and the much better recovery in heel raise test group B than A. Conclusions Two different techniques produced a significant functional improvement, and return to sports. However, this study demonstrated that the minimally invasive technique was recommended for patients with a tendon defect less than 6 cm and who have an urgent demand to return to the sports.
