Gastroesophageal reflux disease (GERD) is a common disorder that has a well-established connection with obesity. To ameliorate the morbidity associated with obesity, bariatric procedures have become an established pathway to accomplish sustained weight loss. In some procedures, such as with the Roux-en-Y gastric bypass surgery, weight loss is also accompanied by the resolution of GERD symptoms. However, other popular bariatric surgeries, such as the sleeve gastrectomy, have a controversial impact on their effect on reflux...

BACKGROUND: The purpose of this study was to examine the long-term overall survival (OS) of colon cancer patients who underwent emergent resection versus patients who were resected electively. METHODS: The 2006-2012 National Cancer Data Base was queried for colon cancer patients who underwent surgical resection. Emergent resection was defined as resection within 24 h of diagnosis. A mixed-effects logistic regression was used to estimate the effect of emergent resection on 30- and 90-day mortality...

BACKGROUND: Thanks to technical advancement in surgery for hepatocellular carcinoma (HCC), hepatic resection (HR) for elderly HCC patients has become safer. However, elderly patients may have shorter long-term survival after surgery if compared with younger patients because of their expected life span. The aim of the present study was to evaluate clinical outcomes and safety after HR in HCC patients aged >75 years (older) compared with HCC patients aged <75 years (younger). METHOD: One hundred sixty-eight patients who underwent HR for HCC from 1998 to 2015 in our Center were analyzed using a prospective database...

BACKGROUND: The prevalence and impact of chronic gastrointestinal dysmotility following total pancreactectomy with islet autotransplantation (TP-IAT) for chronic pancreatitis is not known. METHODS: A cross-sectional study of all patients who underwent TP-IAT at our institution from August 2011 to November 2015 was undertaken. The GCSI (Gastroparesis Cardinal Symptom Index), PAGI-SYM (Patient Assessment of Upper Gastrointestinal Disorders-Symptom Severity Index), PAC-SYM (Patient Assessment of Constipation Symptoms), Bristol stool chart, 12-item Short Form Health Survey (SF-12), and visual analog scale for pain were administered ≥4 weeks following TP-IAT...

INTRODUCTION: We hypothesized that serum neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios may predict pathologic complete response to neoadjuvant chemoradiotherapy in esophageal cancer patients. The ability to predict favorable treatment response to therapy may aid in determining optimal treatment regimens. MATERIALS AND METHODS: A retrospective review of a prospective esophageal disease registry was conducted. Neutrophil-to-lymphocyte ratio was defined as the pre-chemoradiotherapy serum neutrophil count divided by lymphocyte count...

BACKGROUND: Total liver volume (TLV) empirically changes after aggressive preoperative chemotherapy for colorectal liver metastases (CLM). However, the actual degree of changes in normal liver parenchyma and its clinical relevance remain unclear. METHODS: Morphometric data of 110 patients who underwent initial hepatectomy after preoperative chemotherapy were reviewed. TLVs before and after chemotherapy were measured using a computer-based volumetry software and their relevance to clinical factors was investigated...

INTRODUCTION: Hand-assisted laparoscopic surgery (HALS) is often used in procedures too complex for completely minimally invasive approaches. However, there are concerns for whether this hybrid approach abrogates perioperative benefits of the completely minimally invasive technique. METHODS: We queried the 2012-2013 National Surgery Quality Improvement Program for adults undergoing elective HALS or open colectomy (OC). After propensity matching, short-term outcomes were compared...

BACKGROUND: High rates of persistent symptoms are found following cholecystectomy in patients with gallstones. The aim of this population based cohort study was to determine which symptoms were associated with the development of clinical gallstone events in a population unaware of their gallstones. MATERIAL AND METHODS: Three random population samples from Copenhagen (N = 6037) were examined with ultrasound during 1982-1994. Participants were not informed about gallstone status...

BACKGROUND: It is unclear if minimally invasive surgery (MIS) has been universally embraced for paraesophageal hernia (PEH) repair. The aims of this study were: (a) to assess the national utilization of MIS for PEH repair and (b) to compare the perioperative outcomes between MIS and open procedures METHODS: A retrospective population-based analysis was performed using the National Inpatient Sample for the period 2000-2013. Adult patients (≥18 years old) who underwent PEH repair were included...

BACKGROUND: Performance of pancreaticoduodenectomy (PD) in high-volume centers has been posited to improve postoperative morbidity and mortality, consistent with the volume-outcomes hypothesis. We sought to evaluate the impact of hospital volume on 90-day PD outcomes at hepatopancreatobiliary (HPB) centers within a regionalized system. METHODS: A retrospective population-based observational cohort study was performed, using administrative records of patients undergoing PD between 2005 and 2013 in Ontario, Canada...

Najjia N Mahmoud, Elijah W Riddle
Recent guidelines recommend an individualized approach to recurrent uncomplicated diverticulitis, reflecting research showing that non-operative treatment is safe. Thus, the majority of operations for diverticulitis in the future may be for complicated indications. A laparoscopic approach may be used for both acute and chronic complicated diverticulitis in appropriate patients, as described in the American and European guidelines. However, a safe approach to minimally invasive surgery requires recognition when conditions deteriorate or are not suited to laparoscopy as well as knowledge of a variety of technical maneuvers that elucidate difficult anatomy and facilitate resection...

BACKGROUND AND AIM: Liver cirrhosis (LC) and hepatocellular carcinoma (HCC) are associated with viral hepatitis, especially hepatitis B virus (HBV) and hepatitis C virus (HCV). Whether differences exist in postoperative de novo carcinogenesis from established cirrhosis according to viral etiology remains unclear. METHODS: Data from 313 LC patients with viral hepatitis (HBV-LC, n = 108 and HCV-LC, n = 205) who underwent curative-intent hepatectomy for HCC were retrospectively collected...

BACKGROUND: In a randomized trial, pasireotide significantly decreased the incidence and severity of postoperative pancreatic fistula (POPF). Subsequent analyses concluded that its routine use is cost-effective. We hypothesized that selective administration of the drug to patients at high risk for POPF would be more cost-effective. STUDY DESIGN: Consecutive patients who did not receive pasireotide and underwent pancreatoduodenectomy (PD) or distal pancreatectomy (DP) between July 2011 and January 2014 were distributed into groups based on their risk of POPF using a multivariate recursive partitioning regression tree analysis (RPA) of preoperative clinical factors...

Laparoscopy-assisted proximal gastrectomy (LAPG) with esophagogastrostomy using a novel "open-door" technique was introduced recently, with the aim of preventing gastroesophageal reflux. However, quantitate assessment of gastroesophageal reflux after this surgery has not been performed till date. The aims of the current study were to investigate the safety and feasibility of this operation and to elucidate the postoperative reflux status. Twenty consecutive patients (18 men) with (y)cStage I gastric cancer in the upper third of the stomach who underwent LAPG at Kitasato University Hospital from May 2015 through September 2016 were retrospectively reviewed...

The Frey procedure has been demonstrated to be an effective surgical technique to treat patients with painful large duct chronic pancreatitis. More commonly reported as an open procedure, we report our experience with a minimally invasive approach to the Frey procedure. Four consecutive patients underwent a laparoscopic Frey procedure at our institution from January 2012 to July 2015. We herein report our technique and describe short- and medium-term outcomes. The median age was 40 years old. The median duration of pancreatic pain prior to surgery was 12 years...

BACKGROUND: Robotic total mesorectal excision (RTME) for rectal cancer has recently been increasingly used; technical feasibility and short-term outcomes have been reported in detail. Few studies have presented clinical efficacy and mid-term outcomes for a large sample size. The aim of this study is to present oncologic efficacy and mid-term outcomes of robotic total mesorectal excision for rectal cancer and to provide our experiences regarding these surgically challenging issues. METHODS: Three hundred ninety-two patients received RTME between March 2010 and June 2015...

INTRODUCTION: Patients with prior foregut surgery requiring long-term enteral access typically undergo operative jejunostomy tube placement; however, direct percutaneous endoscopic jejunostomy (DPEJ) is a viable alternative. METHODS: All de novo DPEJ procedures performed by surgical and advanced endoscopists from May 2003 to June 2015 were retrospectively reviewed following approval by the Institutional Review Board. There were 59 cases identified. RESULTS: Our cohort had a mean age of 50...

Peritoneal metastasis is common in gastric cancer. It is difficult to treat and carries a poor prognosis. Intraperitoneal (IP) delivery of chemotherapy can attain a higher drug exposure in the peritoneal cavity but with reduced systemic toxicity. Therefore, we hypothesized that IP paclitaxel with systemic chemotherapy would be clinically beneficial for gastric cancer with peritoneal metastases. Patients with unresectable and/or recurrent gastric adenocarcinoma with peritoneal dissemination and/or positive peritoneal washing cytology were recruited...

PURPOSE: Intersphincteric resection (ISR) is an alternative to abdominoperineal resection (APR) for a selected subset of patients with low rectal cancer, combining equivalent oncological outcome and sphincter preservation. However, functional results are heterogeneous and often imperfect. The aim of the present investigation was to determine the long-term functional results and quality of life after ISR. METHODS: One hundred forty-three consecutive patients who underwent surgery for low rectal cancer were analysed...

Surgery remains a cornerstone of the management of Crohn's disease (CD). Despite the rise of biologic therapy, most CD patients require surgery for penetrating, obstructing, or malignant complications. Optimal surgical therapy requires sophisticated operative judgment and medical optimization. Intraoperatively, surgeons must balance treatment of CD complications against bowel preservation and functional outcome. This demands mastery of multiple techniques for anastomosis and strictureplasty, accurate assessment of bowel integrity for margin minimization, and a comprehensive skillset for navigating adhesions and altered anatomy, controlling thickened mesentery, and safely managing the hostile abdomen...
