Compared with single-incision laparoscopy, multiport laparoscopy is associated with greater risk of postoperative wound pain, infection, incisional hernias, and suboptimal cosmetic outcomes. The feasibility of minimally invasive single-incision laparoscopic surgery (SILS) for colorectal procedures is well-established, but outcome data remain limited.(More)
Laparoscopic sigmoidectomy has become the standard procedure in elective surgery for recurrent diverticular disease. To realize further benefits of this minimal invasive procedure and to offer less postoperative pain, shorter recovery time, reduced complications, and improved cosmetic results, attempts are being made to minimize the number of necessary skin(More)
A retrospective review of 78 patients who had undergone endoscopic gastrostomy and 22 patients who had undergone Stamm gastrostomy was carried out. The mean operative time for the Stamm gastrostomy group was 63 min, while that for the endoscopic gastrostomy group was 26 min. One operative complication — bleeding — requiring reoperation occurred in the Stamm(More)
Single-incision laparoscopic surgery (SILS) has been introduced as a new technique for the treatment of various colorectal diseases. Recurrent or complicated diverticulitis of the sigmoid colon is a frequent indication for minimally invasive sigmoid colectomy. The aim of this study was to investigate the impact of obesity on the outcome of SILS sigmoid(More)
The impact of 3-dimensional vector manometry (VM) for characterization of the functional outcome of restorative proctocolectomy (RP) was studied in 61 patients at a median of 86 months after RP for ulcerative colitis. A 14-day continence diary was utilized to quantify continence, urgency, and the frequency of defecation. The clinical outcome data were(More)
The technique of rectal dissection during restorative proctocolectomy might influence the rate of septic complications. The aim of this study was to analyze the morbidity of restorative proctocolectomy in a consecutive series of patients who had rectal dissection with complete preservation of the mesorectum. One hundred thirty-one patients who had(More)
BACKGROUND AND OBJECTIVE Intra-abdominal abscesses are usually polymicrobial and involve a variety of aerobic and anaerobic organisms. Thus, in addition to adequate drainage, empirical coverage with broad-spectrum antimicrobials is central to the management of such abscesses and an understanding of pharmacokinetic properties can be valuable when selecting(More)
Crohn’s disease (CD) of the terminal ileum not responding to standard medical treatment is more and more treated with biologics instead of surgery. In order to get more information on the results of surgery, we analyzed the outcome of laparoscopic ileocecal resection (LICR) performed before the widespread use of these drugs. Chart reviews and telephone(More)
To retrieve the internal cross-piece during removal of a Ponsky-Gauderer PEG, we have sutured the cross-piece to the end of the gastrostomy catheter prior to its insertion endoscopically. As the tube is withdrawn, the internal cross-piece slides off the catheter and remains in the stomach. The cross-piece is then removed by pulling on the suture connecting(More)
Single-incision laparoscopic surgery (SILS) is a new minimally invasive technique which has frequently been applied for treatment of benign colorectal diseases. However, there is still little experience with this technique for the treatment of colorectal cancer. Sixty-eight patients with SILS resections for colon (n = 25) or rectal cancer (n = 43) were(More)
