    Abstract Background: Laparoscopic surgery aims at reducing wound complications and improving cosmetics, among other advantages. High rates of postoperative ventral hernia (POVH) are observed after laparoscopic-assisted colectomies.
    Materials and methods: In a 2011 to 2016 retrospective study of all patients at Rabin Medical Center, we examined POVH prevalence after right hemicolectomy for neoplasia and correlation to specimen extraction site. We also compared laparoscopic-assisted colectomy to hand-assisted laparoscopic colectomy. Included were patients who had postoperative abdominal computed tomography or magnetic resonance imaging scan as part of their routine oncological follow-up to 6 months postsurgery. Patients were excluded for conversion to laparotomy, and prior abdominal surgeries after right colectomy and before follow-up computed tomography/magnetic resonance imaging scan. Demographic and surgical data were collected from patient electronic records, and scans reviewed for POVH by a designated radiologist.
    Results: Of 370 patients, 138 (mean age 70.09 y, 58 males) were included: 54 (39.1%) were diagnosed with POVH, 42/72 (58.3%) at midline extraction site, and 12/66 (18.8%) at off-midline extraction sites (P<0.0001). Surgical site infections and patients positive for tumor metastasis were associated with higher POVH rates. Most (74%) POVHs were identified within 18 months postsurgery (P<0.0001). Body mass index, age, sex, diabetes mellitus, smoking, tumor size, lymph nodes positive for metastasis, and hand-assisted laparoscopic colectomy were not associated with POVH prevalence.
    Conclusion: High rates of radiologically diagnosed POVH were found after laparoscopic-assisted colectomy, with association to midline extraction site, surgical site infections, and positive tumor distant metastasis.

    Abstract Laparoscopic Roux-en-Y gastric bypass (RYGB) is frequently performed as a salvage operation after failed laparoscopic adjustable gastric banding (LAGB). Reports about long-term outcomes are lacking. We assessed the long-term outcomes of RYGB revision surgery after failed LAGB (study group, n = 44) and compared these outcomes with a demographically matched group who underwent primary RYGB (control group, n = 82). There were no between-group differences in sex distribution, age, or initial weight characteristics. At 2 years after RYGB, the mean ΔBMI was 11.8 ± 5.7 kg/m2 in the study group and 15.6 ± 4.2 kg/m2 in the control group (P = 0.01); the corresponding %EWL values were 57% and 78% (P = 0.005). At 6 years after RYGB, the mean ΔBMI was 10 ± 4.5 kg/m2 in the study group and 13.6 ± 5.7 kg/m2 in the control group (P = 0.006); the corresponding %EWL values were 53% and 66% (P = 0.04). In conclusion, this study supports the safety and favorable weight-loss outcome of LAGB revision to RYGB. However, the results are inferior to those of primary RYGB.

    Abstract (1) Background: Over the past several years, there has been a renewed interest with regard to the effect of pre-operative vitamin D levels on post-surgical outcomes. Pre-operative vitamin D deficiency has been associated with many negative post-operative outcomes. However, the role of vitamin D in postoperative outcomes in colorectal liver metastasis (CRLM) resection is relatively uninvestigated. Our study investigated the correlation between preoperative vitamin D levels and postoperative complications in patients undergoing resection for CRLM. (2) Methods: We retrospectively examined the post-operative course of 109 patients, who were evaluated based upon preoperative vitamin D levels: the first group had vitamin D levels less than 25 nmol/L (VIT D < 25 nmol/L) (

    Abstract (1) Background: There is an abundance of literature available on predictors of survival for patients with colorectal liver metastases (CRLM) but minimal information available on the relationship between the primary tumor location and CRLM survival. The studies that focus on the primary tumor location and CRLM survival exhibit a great deal of controversy and inconsistency with regard to their results (some studies show statistically significant connections between the primary tumor location and prognosis versus other studies that find no significant relationship between these two factors). Furthermore, the majority of these studies have been conducted in the West and have studied more diverse and heterogenous populations, which may be a contributing factor to the conflicting results. (2) Methods: We included patients who underwent liver resection for CRLM between December 2004 and January 2019 at two university-affiliated medical centers in Israel: Carmel Medical Center (Haifa) and Rabin Medical Center (Petach Tikvah). Primary tumors located from the cecum up to and including the splenic flexure were labeled as right-sided primary tumors, whereas tumors located from the splenic flexure down to the anal verge were labeled as left-sided primary tumors. (3) Results: We identified a total of 501 patients. Of these patients, 225 had right-sided primary tumors and 276 had left-sided primary tumors. Patients with right-sided tumors were significantly older at the time of liver surgery compared to those with left-sided tumors (66.1 + 12.7 vs. 62 + 13.1,

    Abstract (1) Background: Hand-assisted laparoscopic surgery (HALS) has engendered growing attention as a safe procedure for the resection of metastatic liver disease. However, there is little data available regarding the outcomes of HALS for colorectal liver metastasis (CRLM) in patients over the age of 75. (2) Methods: We compare the short- and long-term outcomes of patients >75-years-old (defined in our study as "elderly patients" and referred to as group 1, G1), with patients <75-years-old (defined in our study as "younger patients" and referred to as group 2, G2). (3) Results: Of 145 patients, 28 were in G1 and 117 were in G2. The most common site of the primary tumor was the right colon in G1, and the left colon in G2 (

    Abstract Purpose: The aim was to compare the short-term and long-term outcomes of patients with metastatic colorectal cancer (CRC) undergoing laparoscopic versus open colorectal resection with simultaneous resection for liver metastases. Currently there is a lack of studies that have investigated the oncosurgical aspects and the short and long-term outcomes from these procedures.
    Materials and methods: A retrospective study of patients who underwent simultaneous resections for CRC and synchronous liver metastases between 2008 and 2019 in 2 university affiliated medical centers.
    Results: Sixty-three patients were identified of whom 21 had successful laparoscopic simultaneous resections. In 43% of patients, the primary tumor was located in the right colon. The 3-year overall survival and disease-free survival rates were 87% and 48%, respectively. When compared with a separate control group of 42 patients who underwent conventional open resections, the laparoscopic approach was associated with an increased operative time (286 vs. 225 min, P=0.05), but a shorter hospital stay (6 vs. 8 d, P=0.008).
    Conclusions: Simultaneous laparoscopic colorectal and parenchymal sparing liver resection for metastatic CRC is safe, feasible, and it is a preferable approach because of better short-term outcome compared with open surgery while not compromising survival and disease recurrence.

    Abstract Background: Surgical myotomy is the best therapeutic option for patients with achalasia. The minimally invasive technique is considered to be the preferred method for many surgeons. Robotic-assisted laparoscopic myotomy has several advantages over conventional laparoscopic surgery. These benefits include more accurate incisions that may result in a lower rate of intra-operative complications.
    Objectives: To describe our technique of performing robotic-assisted Heller myotomy and to review the initial results of this procedure.
    Methods: All patients undergoing robotic-assisted Heller myotomy for achalasia between the years 2012-2018 at Rabin Medical Center were retrospectively reviewed from our institutional prospective database.
    Results: Thirty patients underwent robotic-assisted Heller myotomy for achalasia. Mean operative time was 77 minutes (range 47-109 minutes) including docking time of the robotic system. There were no cases of conversion to laparoscopic or open surgery. There were no cases of intra-operative perforation of the mucosa. None of the patients had postoperative morbidity or mortality. Good postoperative results were achieved in 25 patients. Four patients required additional intervention (3 had endoscopic dilatations and 1 with known preoperative endstage achalasia had undergone esophagectomy). One patient was lost to follow-up.
    Conclusions: Robotic-assisted Heller myotomy is a safe technique with a low incidence of intra-operative esophageal perforation compared to the laparoscopic approach. We believe that robotic-assisted surgery should be the procedure of choice to treat achalasia.
