Operative treatment of athletic pubalgia in competitive athletes: a retrospective study.

BACKGROUND: Athletic pubalgia is an obscure sport injury, presenting mainly with groin pain during twisting movements. The present 15 year study reports outcomes, intraoperative findings and complications of the endoscopic surgical treatment in competitive athletes. METHODS: All competitive athletes, from 2004 to 2018, suffering from athletic pubalgia, treated with laparoscopic Total Extra-Peritoneal technique, at the Department of General, Laparoscopic, Oncologic and Robotic Surgery of the Athens Medical Center were included in this retrospective cohort. Postoperative pain, complications, return to previous training routine and patients' satisfaction were evaluated. RESULTS: A total of 130 patients (115; 88.5% males and 15; 11.5% females) with a mean age of 26.7±7.5 years were evaluated. Preoperatively, mean numeric scale pain was found to be 7.7±1.7. Three days postoperatively, the mean numeric pain scale was 3.4±1.5, showing 55.8% decrease. The mean time for return to sports activity was found to be 6.27±3.02 weeks. Regarding complications, six patients (4.6%) had slight numbness at the groin area during the first 6 postoperative months and one patient (0.8%) suffered from a postoperative hematoma. No recurrence was observed. At the final follow-up (mean 76.58±46.5 months), a total of 97 (74.7%) patients were very satisfied, 31 (23.8%) satisfied and two (1.5%) not satisfied with the outcome. CONCLUSIONS: Laparoscopic operative treatment in competitive athletes suffering from athletic pubalgia seems to offer rapid recovery, rapid return to sports, as well as very low complications rate and no recurrence.

Robotic resection of a giant retroperitoneal leiomyosarcoma: A case report.

The management of abdominal leiomyosarcoma is challenging. Surgical excision is considered the only effective treatment; however, this is associated with considerable morbidity. Robotic surgery has emerged during the past decades and has enhanced the general surgery armamentarium, allowing surgeons to carry out demanding operations in a safe manner. The surgical resection of retroperitoneal leiomyosarcoma (RPLM) can be associated with significant morbidity, which is primarily due to the origin or the close proximity of the tumor with important vascular structures, including the inferior vena cava and tributaries, the duodenum and the ureter. The present case describes the first case of robotic resection of RPLM in a high-volume robotic center. In the present case, a large RPLM was safely removed with respect to oncological principles with the use of the Da Vinci platform.

Enabling single-site laparoscopy: the SPORT platform.

BACKGROUND: The Single Port Orifice Robotic Technology (SPORT) Surgical System by Titan Medical Inc. is designed to overcome the inherent challenges of minimally invasive single-access procedures. The aim of this preclinical study was to evaluate the feasibility of various digestive surgery procedures using this novel surgical robotic platform. METHODS: A total of 12 minimally invasive procedures were performed on six pigs (5 cholecystectomies, 3 Nissen fundoplications, 1 splenectomy and 1 hepatic pedicle dissection) and on one human cadaver (1 cholecystectomy and 1 Nissen fundoplication), by four laparoscopic surgeons. The usability of the device was assessed by means of the modified objective structured assessment of technical skills (OSATS) score that was calculated and analyzed by two independent observers on the recorded videos. Surgeon feedback and recommendations were systematically recorded. RESULTS: All procedures were successfully completed with the SPORT system. In general, surgeons reported to appreciate the intuitive interface and controls, the high-resolution 3D imaging, the dexterity of the end-effectors, and the ergonomic open control platform. Some features requiring optimization were also identified. The modified OSATS score demonstrated a learning curve effect for all device-related tasks. CONCLUSIONS: A variety of abdominal procedures could be safely completed with the current SPORT prototype, in the preclinical setting. This preliminary feasibility experience is promising and encourages further development of single-port robotically assisted surgery.

Impact of multidisciplinary tumor boards on patients with rectal cancer.

Οncological outcomes in patients with primary rectal cancer have markedly improved over the last few years, mainly due to the widespread application of the total mesorectal excision technique. This improvement should also be largely attributed to multiple specialties, other than colorectal surgery, such as radiology, oncology and pathology. Therefore, a multimodal approach is key to efficient and appropriate rectal cancer management. Multidisciplinary tumor (MDT) boards have become an important asset for the management and treatment of patients with rectal cancer, and a number of studies published to date suggest the beneficial effect of the multidisciplinary approach on the management of such patients. The available evidence demonstrates a modification of the treatment plan, attributed to the MDT implementation, in a non-negligible proportion of these patients. However, more studies are required in order to assess the exact impact of MDT boards on disease-free and overall survival of patients with primary rectal cancer.

Cholecystectomy using a novel Single-Site(®) robotic platform: early experience from 45 consecutive cases.

BACKGROUND: The aim of this work was to study the feasibility, safety, and efficacy of single-incision robotic cholecystectomy using a novel platform from Intuitive Surgical. METHODS: All operations were performed by the same surgeon. Parameters assessed included patient history, indication for surgery, operation time, complication rate, conversion rate, robot-related issues, length of hospital stay, postoperative pain, and time to return to work. All patients were followed for a 2-month period postoperatively. RESULTS: Forty-five patients (22 women, 23 men) underwent single-incision robotic cholecystectomy from March 1 to July 15, 2011. There were no conversions to either conventional laparoscopy or laparotomy, although in three cases a second trocar was used. There were no major complications apart from a single case of postoperative hemorrhage. Average patient age was 47 ± 12 years (range = 27-80 years) and average BMI was 30 kg/m(2) (mean = 28.8 ± 4 kg/m(2), range = 18.4-46.7 kg/m(2)). The primary indication for surgery was gallstones. The mean operation time (skin-to-skin) was 84.5 ± 25.5 min (range = 51-175 min), docking time was 5.8 ± 1.5 min (range = 4-11 min), and console time (net surgical time) was 43 ± 21.9 min (range = 21-121 min). Intraoperative blood loss was negligible. There were no collisions between the robotic arms and no other robot-related problems. Average postoperative length of stay was less than 24 h. The mean Visual Analog Pain Scale Score 6 h after the operation was 2.2 ± 1.51 (range = 0-6) and patients returned to normal activities in 4.48 ± 2.3 days (range = 1-9 days). CONCLUSIONS: Single-Site(®) is a new platform offering a potentially more stable and reliable environment to perform single-port cholecystectomy. Both simple and complicated cholecystectomies can be performed with safety. The technique is possible in patients with a high BMI. The induction of pneumoperitoneum using the new port and the docking process require additional training.

Robotic-assisted surgical removal of pelvic schwannoma: a novel approach to a rare variant.

BACKGROUND: Robotic-assisted excision of a pelvic schwannoma is presented. METHODS: A 27 year-old female presented with occasional numbness of the right thigh. Imaging studies revealed a large mass adjacent to the right ovary. Robotic surgery with adjunctive electrophysiological monitoring was performed. The mass was adhered to the L4, L5 roots and was displacing the iliac vessels and the ureter. The tumour bulk was decompressed and total excision was facilitated. RESULTS: Pathology revealed a neoplasm consisting of spindle cells. Immunochemistry revealed S-100(+) and a growth index Ki-67 < 1%. These findings were consistent with the diagnosis of ancient schwannoma. The intraoperative time was comparable to laparoscopy and the patient had an uneventful recovery. CONCLUSION: Ancient schwannoma is often diagnosed only when it is large enough to produce symptoms. Robotic surgery with adjunctive electrophysiological monitoring is a safe technique for the removal of large pelvic neurinomas.

A decade of laparoscopic appendectomy: presentation of 1,026 patients with suspected appendicitis treated in a single surgical department.

BACKGROUND: The laparoscopic approach for suspected appendicitis is increasingly gaining acceptance. Nevertheless, the discussion on its safety, efficacy, indications, and diagnostic accuracy remains open. METHODS: During the decade 1993-2003, 1026 patients with suspected appendicitis were approached by laparoscopy. Sixty-three patients (6.1%) had chronic recurrent symptoms. Data were collected retrospectively and analyzed. There were 587 female and 439 male patients. Fertile women were compared to all other patients with respect to the diagnostic accuracy of laparoscopy. RESULTS: Conversion rate was 0.55%. Median operating time was 26 minutes. Overall complication rate was 5.7%, consisting mostly of minor complications. There were no major intraoperative complications. Wound infections and intra-abdominal abscesses were reviewed separately and were 1.1% and 0%, respectively. Diagnosis could be established via laparoscopy in 89% of all patients, 85.4% of fertile women, and 93.1% of patients except fertile women. A median of 4 minor analgesics and 2 narcotics were required after surgery. The median time until bowel movements, intake of solid food, and the median length of hospital stay were 24, 48, and 30 hours, respectively. Patients returned to normal activity after a median of 7 days. There was no mortality. There was 1 reoperation. Follow-up lasted 4 weeks. CONCLUSION: Laparoscopic appendectomy is a well-justified procedure in the treatment of acute and chronic appendicitis. If there is enough experience, patients can profit from a higher diagnostic accuracy, quicker return of bowel habits, less postoperative pain, shorter hospital stay, and a faster return to normal activities than is reported for the open procedure. Especially, fertile women can profit from these advantages. This abstract has been presented as a poster in the SAGES Conference 2004.
