[Show abstract][Hide abstract] ABSTRACT: Introduction. Pelvic floor dysfunction syndromes present with voiding, sexual, and anorectal disturbances, which may be associated with one another, resulting in complex presentation. Thus, an integrated diagnosis and management approach may be required. Pelvic muscle rehabilitation (PMR) is a noninvasive modality involving cognitive reeducation, modification, and retraining of the pelvic floor and associated musculature. We describe our standardized PMR protocol for the management of pelvic floor dysfunction syndromes. Pelvic Muscle Rehabilitation Program. The diagnostic assessment includes electromyography and manometry analyzed in 4 phases: (1) initial baseline phase; (2) rapid contraction phase; (3) tonic contraction and endurance phase; and (4) late baseline phase. This evaluation is performed at the onset of every session. PMR management consists of 6 possible therapeutic modalities, employed depending on the diagnostic evaluation: (1) down-training; (2) accessory muscle isolation; (3) discrimination training; (4) muscle strengthening; (5) endurance training; and (6) electrical stimulation. Eight to ten sessions are performed at one-week intervals with integration of home exercises and lifestyle modifications. Conclusions. The PMR protocol offers a standardized approach to diagnose and manage pelvic floor dysfunction syndromes with potential advantages over traditional biofeedback, involving additional interventions and a continuous pelvic floor assessment with management modifications over the clinical course.

[Show abstract][Hide abstract] ABSTRACT: Single-incision laparoscopic right hemicolectomy has been shown to be safe and feasible; however, it remains technically demanding. We present a single-incision laparoscopic right hemicolectomy with an inferior-to-superior approach with intracorporeal anastomosis. This approach may help overcome some of the technical challenges of the conventional technique.
With the patient in steep Trendelenburg and right-side elevated, a single-incision device is placed at the umbilicus. The small bowel is mobilized out of the pelvis, exposing the ileocolic peritoneal attachments. The peritoneum is divided and the retroperitoneal plane is established in a cranial and medial fashion until the duodenum is exposed. The ileocolic pedicle is readily identified and divided. Further exposure of the retroperitoneal plane is developed and the right branch of the middle colic vessel is isolated and divided. Attention is drawn to the remaining attachments of the hepatic flexure, which is then taken down. The resection margins of the transverse colon and terminal ileum are identified and a side-to-side intracorporeal anastomosis using a double-stapled technique is performed.
Technical challenges of the single-incision laparoscopic right hemicolectomy may be overcome utilizing an inferior-to-superior approach with intracorporeal anastomosis by affording optimal exposure, retraction, and dissection of the tissue planes.
[Show abstract][Hide abstract] ABSTRACT: Single-incision laparoscopic colectomy (SILC) has emerged as a viable minimally invasive surgical approach with benefits and limitations yet to be fully elucidated. Although shown to be safe and feasible, characterization of the learning curve has not been addressed. Our aim was to identify a learning curve for SILC right hemicolectomy and to determine the incidence of operative failure and complication rates during this phase.
Over a 2-year period, data from 54 consecutive SILC cases performed by the same surgeon were tabulated in an institutional review board-approved database. A learning curve was generated utilizing cumulative sum (CUSUM) methodology to assess changes in total operative time (OT) across the case sequence. A separate learning curve was generated utilizing risk-adjusted CUSUM analysis, taking into account patient risk factors (i.e., age, American Society of Anesthesiologists score, body mass index, prior abdominal surgeries, and tumor size for malignant cases) and operative failure (i.e., prolonged OT, conversion to open surgery, intraoperative and 30-day postoperative complications, prolonged length of stay, reoperation, readmission, and mortality).
Patients had a mean age of 63.6 ± 11.5 years, mean body mass index of 27.3 ± 3.9 kg/m(2), and median American Society of Anesthesiologists score of 2. Mean OT and length of stay were 123.5 ± 28.9 min and 3.9 ± 2.4 days, respectively. There were no conversions or oncologic failures. Six patients developed 30-day postoperative complications. CUSUM analysis of OT identified achievement of the learning phase after 30 cases. When taking into account both analyses, the rate of operative failure was not statistically different between the initial 30 and the final 24 cases.
In our experience, the learning curve is achieved between 30 to 36 cases. Offering this minimally invasive surgical approach does not result in increased complications or harmful results even in the early phases of the learning curve.
[Show abstract][Hide abstract] ABSTRACT: Introduction. Single-incision laparoscopic colectomy (SILC) is a viable and safe technique; however, there are no single-institution studies comparing outcomes of SILC for colon cancer with well-established minimally invasive techniques. We evaluated the short-term outcomes following SILC for cancer compared to a group of well-established minimally invasive techniques. Methods. Fifty consecutive patients who underwent SILC for colon cancer were compared to a control group composed of 50 cases of minimally invasive colectomies performed with either conventional multiport or hand-assisted laparoscopic technique. The groups were paired based on the type of procedure. Demographics, intraoperative, and postoperative outcomes were assessed. Results. With the exception of BMI, demographics were similar between both groups. Most of the procedures were right colectomies (n = 33) and anterior resections (n = 12). There were no significant differences in operative time (127.9 versus 126.7 min), conversions (0 versus 1), complications (14% versus 8%), length of stay (4.5 versus 4.0 days), readmissions (2% versus 2%), and reoperations (2% versus 2%). Oncological outcomes were also similar between groups. Conclusions. SILC is an oncologically sound alternative for the management of colon cancer and results in similar short-term outcomes as compared with well-established minimally invasive techniques.

[Show abstract][Hide abstract] ABSTRACT: : Initially described in 2008, single-incision laparoscopic colectomy has evolved into a safe and feasible surgical approach. Noted advantages include elimination of trocar-site incisions and improved cosmesis. Additional benefits including reduced abdominal wall trauma, diminished pain, and shorter length of hospitalization have been proposed. Following utilization in over 150 colectomies, we present a standardized approach and describe our technique for single-incision laparoscopic sigmoid resection through a single-port access device.
: A 2.5-cm umbilical incision is used for insertion of the single-incision access device. A 30° 5-mm camera with a right-angle light cord adaptor and 2 bowel graspers are inserted through the access device. Exploration and lysis of adhesions are performed before placing the patient in a steep Trendelenburg position with 20° left-sided elevation. Dissection commences in a medial-to-lateral fashion, developing the presacral avascular plane while ensuring nerve preservation. The retroperitoneal plane is established from the sacral promontory to the lateral peritoneal reflection. After identification of the left ureter and isolation of the vascular pedicle, the inferior mesenteric artery is isolated and ligated. The lateral attachments of the left colon and rectosigmoid are then divided, followed by additional pelvic dissection along the presacral avascular plane. The mesentery of the distal resection margin is divided before transection of the corresponding bowel using a stapling device. The bowel is then extracted and resected at the site of the single-incision access device. An intracorporeal primary end-to-end anastomosis is fashioned.
: We present a dynamic article with video illustrating a standardized medial-to-lateral approach for single-incision laparoscopic sigmoid resection. The technique effectively avoids the use of multiple trocar sites, maintains basic oncologic principles of resection, and affords the benefits of minimally invasive surgery.

[Show abstract][Hide abstract] ABSTRACT: Background:
Transanal endoscopic video-assisted (TEVA) excision represents an alternative approach for the surgical treatment of middle and upper rectal lesions not amenable to colonoscopic removal. Utilizing principles of single-incision laparoscopic surgery, this novel minimally invasive approach optimizes access for safe and complete removal of these lesions without the need for a formal rectal resection. We describe our technique and early outcomes with TEVA excision.
Between March 2010 and September 2011, TEVA excision was performed for patients presenting for management of rectal lesions not amenable to colonoscopic or standard transanal removal. Patients were selected if they presented with benign disease or superficial adenocarcinoma, and the proximal extent of the lesion extended beyond 8 cm from the anal verge. Demographic, intraoperative, and postoperative data were assessed. A SILS™ port was placed in the anal canal for access in all cases. Standard laparoscopic instruments were utilized for visualization, full-thickness transanal excision, and primary closure.
Twenty patients (50% male) with a mean age of 64.6 ± 10.9 years, mean body mass index of 28.2 ± 4.9 kg/m(2), and median American Society of Anesthesiologist score of 2 underwent TEVA excision. Fourteen patients (70%) presented with benign disease and six patients (30%) presented with malignant disease. The mean size of the lesions was 3.0 ± 1.4 cm, and the mean distance from the anal verge was 10.6 ± 2.4 cm. All excisions were successfully completed with a mean operative time of 79.8 ± 25.1 (range, 45-135) min. The mean length of hospital stay was 1.1 ± 0.7 (range, 0-3) days.
TEVA excision is a safe and feasible approach for local excision of rectal lesions not otherwise amenable to standard techniques. Continued investigation and development will be important to establish its role in minimally invasive colorectal surgery.
[Show abstract][Hide abstract] ABSTRACT: Single-incision laparoscopic colectomy has developed into a viable option for the treatment of benign and malignant colorectal diseases with the innovation of new access devices, instrumentation, and surgical techniques. Although cosmesis has been highly touted as the most apparent advantage of the approach, the single-incision platform also affords the potential for enhanced recovery, early hospital discharge, and reduction in postoperative wound complications. Despite increasing evidence demonstrating the safety and efficacy of single-incision laparoscopic colectomy, wide-ranging adaptation has been tempered in part as a result of the technical demands of the approach. We aim to describe our surgical pearls for overcoming various pitfalls and technical challenges experienced during single-incision laparoscopic colectomy to facilitate successful application of this technique.
[Show abstract][Hide abstract] ABSTRACT: Background Single-incision laparoscopic surgery is an emerging modality that has proven to be safe and feasible for colon resection in multiple case reports and series. Nonetheless, comparative analyses with established techniques are limited in the published literature. We evaluated the efficacy of single-incision laparoscopic colectomy (SILC) for the treatment of sigmoid disease through a matched-case comparison with conventional laparoscopic colectomy (CLC). Methods Twenty patients who underwent single-incision laparoscopic sigmoid resection for benign or malignant disease between July 2009 and September 2010 were matched to patients who underwent conventional laparoscopic sigmoid colectomy. Demographic, intraoperative, and postoperative data were assessed. Results Twenty SILC and CLC cases each were paired based on gender (p p p p p p p p p p Conclusion Compared with conventional laparoscopic technique, single-incision laparoscopic surgery results in similar intraoperative and postoperative outcomes. The technique avoids use of multiple trocar sites and may safely be performed in patients with a history of previous abdominal surgery while maintaining a short length of hospital stay and low complication rate.
