Single-port laparoscopic colectomy

Safety and Efficacy of Single-Port Laparoscopic Ileostomy in Palliative Settings

Purpose

Single-port laparoscopic techniques can be optimized with confined incisions. This approach has an intraoperative advantage of excellent visualization of the correct intestinal segment for exteriorization, along with direct visual control of the extraction to avoid twisting. However, only a few studies have verified the efficacy of the technique. Thus, this study assessed the results of single-port laparoscopic stoma creation for fecal diversion, specifically focusing on feasibility, safety, and efficacy.

Methods

Patients who underwent single-incision enterostomy performed by a single surgeon were included. Data on demographics, indications for and chosen procedure, and operation results were retrospectively collected and analyzed.

Results

Between April 2015 and January 2018, a total of 13 patients (8 males, 5 females) with a mean age of 57.7 years (range, 41–83 years) underwent single-port ileostomy creation. The most common reason for diversion was palliative ileostomy for colon obstruction or fistula from peritoneal malignancy (n = 12), followed by colonic fistula with necrotizing pancreatitis (n = 1). There were no cases of conversion to open or multiport laparoscopic surgery. The mean operative time was 54 minutes (range, 37–118 minutes), and the median length of hospital stay was 8 days (range, 2–211 days). A postoperative complication, aspiration pneumonia, was documented in 1 patient and treated conservatively. The mean duration of bowel movement was 0.7 days (range, 0–4 days). All stomas had good function, and there was no 30-day mortality.

Conclusion

Single-port laparoscopic ileostomy in patients with a palliative setting could be a safe and feasible option for fecal diversion.

Single-incision laparoscopic colorectal surgery: a report of 33 cases in Saudi Arabia

BACKGROUND

Single-incision laparoscopic surgery (SILS) has gained worldwide acceptance as a minimally invasive technique in colorectal procedures since its introduction in 2008. However, case series on its feasibility and safety in Saudi Arabia are lacking.

OBJECTIVE

Evaluate the operative results and clinical outcome of single-port laparoscopic procedures in colorectal surgeries.

DESIGN

Retrospective.

SETTING

This study was conducted at King Khalid university Hospital, Riyadh, Saudi Arabia.

PATIENTS AND METHODS

Demographic and clinical data, including pathology, and intraoperative and postoperative outcomes, were prospectively collected in patients undergoing SILS. This study was conducted during the period from January 2010 and October 2014.

MAIN OUTCOME MEASURES

Demographic and postoperative outcomes in patients undergoing SILS colectomies.

RESULTS

Thirty-three (33) patients underwent SILS. The mean (SD) age was 51 years (18.2 years), and the average body mass index was 26.6 (6.9) kg/m2. Patients were primarily diagnosed with cancer (n=20/33, 61%), inflammatory bowel disease (n=12/33, 36%) and diverticulitis (n=1/33, 3%). Procedures included anterior resection (n=9/33, 27%), ileocecal resection (n=8/33 24%), hemicolectomy (n=7/33, 21%), extended right hemicolectomy (n=5/33, 15%) and total colectomy (n=4/33, 12%). The mean SD operative time was 212 minutes (76.4 minutes). The mean SD size of the extraction incision was 4.2 (1.7) cm. Six percent of the cases were converted to open (n=2/33), and 9% required placement of an extra port (n=3/33). Four (12%) patients had intraoperative complications, and 30% experienced postoperative complications. The average length of hospital stay was 6.4 (4.3) days.

COCNLUSIONS

SILS is technically feasible and safe for patients undergoing colorectal surgery with no unusual complications. However, comparative studies are necessary to validate the potential benefits of SILS over conventional colorectal laparoscopic surgery.

LIMITATIONS

The study lacked a comparison to conventional open procedures. Additionally, some evaluation criteria were not considered, including cosmesis, pain control, patient satisfaction and cost effectiveness.

Experience of single-incision laparoscopy in children

CONTEXT

Laparoscopic surgery is commonly used for the treatment of many pediatric surgical diseases at our department. Single-incision laparoscopic surgery (SILS) is well-known for its cosmetic benefit. We, hereby, present our experience of SILS and evaluate its efficacy.

MATERIALS AND METHODS

From July 2012 to June 2014, 78 patients aged less than 18 years who underwent SILS were retrospectively evaluated. There were 44 males and 34 females, with a mean age of 10.3 years. The procedures included appendectomy (n = 64), reduction of intussusception (n = 8), removal of an intestinal foreign body (n = 3), and Meckel's diverticulectomy (n = 3). We compared the patients who underwent SILS with those who underwent conventional laparoscopic surgery (CLS), regarding these procedures. The parameters for analysis included the patient's demographic data, surgical indication, complications, operative time, and length of hospital stay.

CONCLUSION

SILS is comparable to CLS regarding two major procedures, namely, appendectomy and reduction of intussusception. There were no significant differences between the two groups regarding the patients' demographic data, complications, and length of hospital stay. According to our experience of SILS, it could be a feasible and safe procedure for the treatment of various pediatric surgical diseases. However, large prospective randomized studies are needed to identify the differences between SIL and CLS.

Dual-port laparoscopic abdominoperineal resection using the intended stoma site as the multichannel port

We describe a novel minimally invasive procedure: dual-port laparoscopic abdominoperineal resection using a SILS port, and report our experience of using this to treat ten patients with lower rectal cancer. A SILS port was placed in the left lower quadrant at the intended colostomy site. A 5-mm trocar was inserted at the umbilicus at the subsequent drain site. Via a standard laparoscopic medial-to-lateral approach, the inferior mesenteric artery and vein were ligated and total mesorectal excision was performed. Via a perineal approach, the specimen was retrieved from the perineal wound, and a sigmoid colostomy was created at the site of the SILS port. Ten consecutive patients with lower rectal cancer at clinical stage T3 or lower underwent the procedure at our institution. The procedure was completed successfully in all patients, without any intraoperative problems and all postoperative outcomes were satisfactory. Thus, dual-port laparoscopic abdominoperineal resection can be performed safely and feasibly in selected patients.

Single-port laparoscopic colorectal resections in obese patients are as safe and effective as conventional laparoscopy

BACKGROUND

Obese patients pose additional operative technical difficulties, and it is unclear if the outcomes of single-port colorectal surgery are equivalent to those of conventional laparoscopy in such patients. The aim of this study was to compare perioperative variables and short-term outcomes of single-port versus conventional laparoscopy in obese patients undergoing colorectal surgery.

PATIENTS AND METHODS

Obese patients (BMI ≥ 30 kg/m(2)) undergoing single-port laparoscopic colorectal resections between March 2009 and September 2012 were case matched 1:1 with obese counterparts undergoing conventional (multi-port) laparoscopic surgery based on diagnosis and operation type.

RESULTS

Thirty-seven patients who underwent single-port surgery were matched with 37 conventional laparoscopic counterparts. Male gender predominated in the single-port group (26 vs 15, p = 0.02). The number of patients with a history of previous abdominal operations (17 vs 13, p = 0.48) and ASA score (3 vs 2, p = 0.6) were similar between the groups. No differences were observed with respect to conversion rate (2 vs 5, p = 0.43), operative time (146 vs 150 min, p = 0.48), estimated blood loss (159 vs 183 ml, p = 0.99), time to first flatus (3 vs 3 days, p = 0.91), time to first bowel movement (3 vs 4 days, p = 0.62), length of hospital stay (7 vs 6 days, p = 0.37), or reoperation (2 vs 1, p > 0.99), and readmission rates (2 vs 2, p > 0.99). There were no deaths.

CONCLUSION

For obese patients undergoing colorectal resections, single-port laparoscopy appears to be as safe and effective as conventional laparoscopy.
