    ABSTRACT: Splenic cysts are relatively rare clinical entities and are often diagnosed incidentally upon imaging conducted for a variety of clinical complaints. They can be categorized as primary or secondary based on the presence or absence of an epithelial lining. Primary cysts are further subdivided into those that are and are not secondary to parasitic infection. The treatment of non-parasitic splenic cysts (NPSC) has historically been dictated by two primary factors: the presence of symptoms attributable to the cyst and cyst size greater or less than 5 cm. While it is appropriate to resect a symptomatic lesion, the premise of recommending operative intervention based on size is not firmly supported by the literature.

    ABSTRACT: The purpose of this study was to demonstrate the feasibility of performing peroral endoscopic myotomy (POEM) in the management of recurrent achalasia after failed myotomy. Eight patients presented to our institution between October 2010 and June 2013 with recurrent/persistent symptoms after prior laparoscopic Heller myotomy. Three patients underwent redo laparoscopic Heller myotomy, and five patients consented to redo myotomy with POEM. Demographics were similar between the groups with exception of age (POEM 69.5 vs. laparoscopic Heller myotomy (LHM) 34.5, p = 0.003). Preoperative Eckardt scores, motility, and prior interventions were not significantly different. Three patients who underwent POEM and two who underwent laparoscopic Heller myotomy had prior fundoplication. There was one perforation identified after laparoscopic Heller myotomy and one patient with persistent subcutaneous emphysema after POEM. Both POEM and laparoscopic Heller myotomy demonstrated significant improvement in symptoms and Eckardt scores at average follow-up of approximately 5 months (p < 0.05). POEM is a feasible option for patients after failed myotomy even in the presence of prior fundoplication. The procedure can be performed safely using a similar technique as for primary myotomy with the exception of creating the myotomy laterally along the right side of the esophagus and lesser curvature avoiding the previous anterior myotomy.

    ABSTRACT: Our objective was to compare hospital charges and both perioperative and mid-term quality of life between single- (SILC) and multi-incision (MILC) laparoscopic cholecystectomy in a randomized controlled trial. Patients with acute or chronic biliary disease were invited to participate. Pain scores, quality of life, and perioperative outcomes were measured. Patients were followed for 1 year postoperatively in the clinic with examination to document hernia formation. One hundred subjects were randomized to SILC (n = 49) or MILC (n = 51). Demographics were similar for both groups except more women underwent SILC (86% vs 67%, P = .026). Operative time was greater for SILC (63.5 ± 21.0 vs 43.8 ± 24.2 minute, P < .0001). Five SILC patients required added ports. One substantial complication occurred in SILC. Pain, the use of analgesics, and duration of hospital stay were equal between groups; however, charges were greater in the SILC group ($17,602 ± $6,089 vs $13,342 ± $8,197, P < .0001). Both groups reported similar quality of life and cosmesis. At an average follow-up of SILC (16.4 ± 12.1 months) and MILC (16.2 ± 10.5 months), no novel umbilical hernias were identified. SILC results in longer operative time and greater hospital charges with similar pain and quality of life scores compared with a standard laparoscopic approach.

    ABSTRACT: We report our short-term experience with peroral endoscopic myotomy (POEM) and compare perioperative outcomes with laparoscopic Heller myotomy (LHM) for achalasia. Patients from an institutional review board-approved protocol underwent POEM and were followed prospectively. Comparisons were made, in a prospective esophageal database, with patients who underwent LHM over the same period. We studied 18 patients who underwent POEM and compared them to 21 who underwent LHM. Demographics, preoperative Eckardt scores, motility data, and prior intervention history were comparable. Operative time, myotomy length, and complication rates (1 perforation in each group) were equal. Postoperative pain was significantly different by visual analogue score (POEM 3.9 ± 0.6 versus LHM 5.7 ± 0.4, P = .02) and analgesic use (POEM 26.0 ± 13.7 versus LHM 90.0 ± 48.5 mg morphine, P = .02). Return to activities of daily living was significantly faster in the POEM group (2.2 ± 0.6 vs 6.4 ± 1.0 days, P = .03). Postoperative dysphagia and Eckardt scores were equally successful in both groups. POEM results in similar relief of dysphagia with less postoperative pain and quicker return to normal activities.

    ABSTRACT: Since the development of single-incision surgery, several retrospective studies have demonstrated its feasibility; however, randomized prospective trials are still lacking. We report a prospective randomized single-blinded trial with a cost analysis of single-incision (SI) to multi-incision (MI) laparoscopic cholecystectomy. After obtaining IRB approval, patients with chronic cholecystitis, acute cholecystitis, or biliary dyskinesia were offered participation in this multihospital, multisurgeon trial. Consenting patients were computer randomized into either a transumbilical SI or standard MI group; patient data were then entered into a prospective database. We report 79 patients that were prospectively enrolled and analyzed. Total hospital charges were found to be significantly different between SI and MI groups (MI $15,717 ± $14,231 vs SI $17,817 ± $5,358; p < 0.0001). Broken down further, the following subcharges were found to also be significant: operating room charges (MI $4,445 ± $1,078 vs SI $5,358 ± 893; p < 0.0001); medical/surgical supplies (MI $3,312 ± $6,526 vs SI $5,102 ± $1,529; p < 0.0001); and anesthesia costs (MI $579 ± $7,616 vs SI $820 ± $23,957; p < 0.0001). A validated survey (ie, Surgical Outcomes Measurement System) was used to evaluate various patient quality-of-life parameters at set visits after surgery; scores were statistically equivalent for fatigue, physical function, and satisfaction with results. No difference was found between visual analogue scale scores or inpatient and outpatient pain-medication use. We show SI surgery to have higher costs than MI surgery with equivalent quality-of-life scores, pain analogue scores, and pain-medication use.

    ABSTRACT: Several complications after esophagectomy with gastric pull-up are associated with ischemia within the gastric conduit. The aim of this study is to assess the feasibility of laparoscopic ischemic preconditioning of the stomach prior to thoracotomy, esophagectomy, and gastric pull-up with an intrathoracic anastomosis. A retrospective review of 24 consecutive patients between October 2008 and July 2011 with esophageal adenocarcinoma (stage I-III) undergoing laparoscopic gastric ischemic conditioning prior to esophagectomy was conducted. Conditioning included laparoscopic ligation of the left and short gastric arteries, celiac node dissection, and jejunostomy tube placement. Formal resection and reconstruction was then performed 4-10 days later. Of the 24 patients, 88% received neoadjuvant chemotherapy/radiation therapy. Twenty-three of the 24 patients underwent successful laparoscopic ischemic conditioning and subsequent esophagectomy. Total mean number of lymph nodes harvested was 21.8 (±8.0), and a mean of 5.3 (±2.4) celiac lymph nodes identified. There were no conversions to an open procedure. Length of stay was 3.8 (±4.8) days with a median length of stay of 2 (1-24) days. Three patients experienced anastomotic leak, six patients experience delayed gastric emptying, and two patients developed anastomotic stricture. There were no surgical site infections. R0 resection was achieved in all patients who underwent laparoscopic ischemic conditioning followed by esophagectomy. Laparoscopic ischemic conditioning of the gastric conduit has been shown to be feasible and safe.

    ABSTRACT: BACKGROUND: Parastomal hernia (PH) is a frequent complication of stoma formation, occurring in 35-50 % of patients. Recurrence after repair is common, ranging from 24 to 54 % of cases. We hypothesized that repair using a laparoscopic modified Sugarbaker technique (SB) would result in a superior recurrence rate when compared with other repairs. METHODS: An Institutional Review Board-approved retrospective review of patients who underwent PH repair between 2004 and 2011 was performed. We collected demographics, factors related to ostomy formation, risk factors for hernia, intraoperative and postoperative information, as well as the absence or presence of PH on their last physical examination or imaging study. RESULTS: Forty-nine PH repairs were performed: 33 (67 %) para-ileostomy and 16 (33 %) para-colostomy. Repairs included 14 laparoscopic modified SB, 19 laparoscopic keyhole, 11 ostomy re-sitings, and 5 open primary repairs. There was no statistically significant difference between groups when comparing age, BMI, smoking status, steroid use, ostomy type, location, primary diagnoses, or complication rate. Recurrence rates were 0 % for SB, 58 % for keyhole, 64 % for re-siting, and 20 % for open repair. When SB was compared with all groups, the incidence of recurrence was significantly lower (p < 0.001) but follow-up was as well (7.2 vs 32.7 months). When analysis was restricted to the 28 repairs performed between 2009 and 2011, there was no significant difference between the groups in terms of demographics or follow-up period (7.2 months for SB group versus 11.8 months for all others), but again there was a significant difference in recurrence (0 of 14 for the SB group vs 8 of 14, p < 0.01). In addition, there were no differences in postoperative complication rates among all techniques. CONCLUSION: The modified SB technique may offer patients a significant decrease in the risk of recurrence compared with other PH repair techniques with no significant increase in postoperative complications.
