Decreasing morbidity and mortality in 100 consecutive minimally invasive esophagectomies.

INTRODUCTION: Esophagectomy is a complex invasive procedure that requires exploration of multiple body cavities for removal and subsequent restoration of gastrointestinal continuity. In many institutions, esophagectomy morbidity and mortality rates remain high despite improvement of intensive care treatment. We reviewed our minimally invasive esophagectomy (MIE) experience of a consecutive series of 100 patients to analyze trends in morbidity and mortality as we transitioned from open to MIE. METHODS: A total of 105 consecutive patients who underwent operative exploration for esophagectomy from August 2007 to January 2011 were reviewed. The preoperative evaluation, operative technique, and postoperative care of these cases were evaluated and analyzed for 100 patients who have had a MIE and compared with 32 open esophagectomies 2 years prior. RESULTS: During the time frame of the study, 105 patients underwent an exploration for attempted esophagectomy. Resection was completed in 100 patients and was done for malignant disease in 95 patients and benign disease in 5 patients. There was one in hospital mortality due to a pulmonary embolism. There was no significant difference in postoperative complications consisting of transient left recurrent nerve injury (7 vs. 12.5%) or pneumonia (9 vs. 15.6%) in those who underwent MIE compared with open resection. However, wound infections were significantly less in patients who underwent MIE compared with open esophagectomy (1 vs. 12.5%, respectively, p = 0.01). Anastomotic leak (4 vs. 12.5%, p = 0.05) also was lower in those who underwent MIE. Median length of stay (LOS) was significantly less in patients who underwent MIE compared with open esophagectomy (7.5 vs. 14 days, p < 0.05). Finally, there was a trend toward improvement in median LOS in the 30 patients who underwent MIE during the most recent time period compared with the initial 17 patients who underwent MIE (7.5 vs. 10 days, p = 0.05) CONCLUSIONS: Our results support the continued safe use of esophagectomy for selected esophageal diseases, including malignancy. Morbidity, especially wound infection, anastomotic leak, and length of stay is decreasing with the incorporation of minimally invasive techniques.

Gastroesophageal reflux after sleeve gastrectomy in morbidly obese patients.

BACKGROUND: Gastroesophageal reflux disease (GERD) is highly prevalent in morbidly obese patients and a high body mass index is a risk factor for the development of this co-morbidity. The effect of laparoscopic sleeve gastrectomy (LSG) on GERD is poorly known. METHODS: We studied the effect of LSG on GERD in patients with morbid obesity. A retrospective review of 28 consecutive patients undergoing LSG for morbid obesity from September 2008 to September 2010 was performed. RESULTS: A total of 28 patients, 18 women and 10 men, were identified, with a mean age of 42 years (range 18-60). The mean weight and body mass index was 166 kg and 55.5 kg/m2, respectively. The mean percentage of excess weight loss was 40% (range 17-83), with a mean follow-up time of 32 weeks (range 8-92). All patients had a pre- and postoperative upper gastrointestinal radiographic swallow study as a part of their routine care. Of these patients, 18% were noted to have new-onset GERD on their postoperative upper gastrointestinal swallow test after their LSG procedure. Using the GERD score questionnaire, all patients were interviewed to evaluate their reflux symptoms. We had a 64% response rate, with 22% of patients indicating new-onset GERD symptoms despite receiving daily antireflux therapy. All respondents were extremely happy with their surgery and weight loss to date. CONCLUSION: LSG might increase the prevalence of GERD despite satisfactory weight loss. Additional studies evaluating esophageal manometry and ambulatory 24-hours pH-metry are needed to better evaluate the effect of LSG on gastroesophageal reflux symptoms.

Retrograde jejunojejunal intussusception status following Roux-en-Y gastrojejunostomy.

Reported herein is an experience with retrograde intussusception. The index case was a 25-year-old African American woman who was status post-multiple previous intraperitoneal procedures, including a truncal vagotomy, distal gastrectomy, and Roux-en-Y gastrojejunostomy for the treatment of gastric outlet obstruction secondary to type 2 peptic ulcer disease. The patient presented most recently with symptoms and signs of a high-grade mechanical intestinal obstruction. Preoperatively, computerized axial tomography revealed retrograde intussusception. Urgent exploratory celiotomy confirmed retrograde intussusception of a segment of the common channel just distal to the jejunojejunostomy. The jejunojejunostomy, including the nonreducible intussusceptum and intussuscipiens, was resected. The alimentary tract was reconstituted in conventional fashion. Light microscopic histopathologic analysis revealed acute greater than chronic inflammation, transmural edema, ischemia/necrosis of the intussusceptum, and hypertrophy of the intussuscipiens. Mechanistically, intussusception has been characterized as an internal prolapse. It usually is aboral/antegrade/isoperistaltic in direction with circumferential intraluminal invagination/prolapse/propagation/telescoping of the proximal/cephalad intussusceptum into the distal/caudad intussuscipiens. Retrograde intussusception is the reverse. More specifically, retrograde intussusception is adoral/retrograde/antiperistaltic in direction with circumferential extraluminal exvagination/propagation/telescoping of the proximal/cephalad intussuscipiens over and around the distal/caudad intussusceptum. We speculate that suture lines, staple lines, adhesive disease, and incomplete closure of mesenteric defects are proximate and determinant causes of retrograde intussusception.

Incidence of surgical site infections postcolorectal resections without preoperative mechanical or antibiotic bowel preparation.

This study was performed to determine the incidence of surgical site infections (SSIs) after colorectal resection in patients without mechanical or antibiotic bowel preparation. A retrospective review of the medical records of 136 consecutive patients undergoing an elective colorectal resection between April 2004 and April 2006 was performed. Indications for colon resection in this series were malignant neoplasia (48%), inflammatory bowel disease (18%), diverticular disease (17%), or other benign disease (17%). Overall, an SSI occurred in 31 patients (23%). An SSI occurred in 16 of 90 patients (17.8%) who received antibiotics within 1 hour before surgery and in 15 of 46 patients (33.3%) who did not receive antibiotics in a timely manner (P < 0.05). An SSI occurred in seven of 15 patients (46.7%) who received bowel preparation but in only 24 of 121 patients (19.8%) who did not receive either mechanical or antibiotic bowel preparation (P < 0.029). SSIs were not associated with age, gender, diagnosis, length of procedure, preoperative steroid use, diabetes mellitus, or previous celiotomy. This series shows administration of perioperative antibiotics within 1 hour before surgery is associated with a significant decrease in the incidence of SSI and bowel preparation can be safely omitted.
