Laparoscopic Magenstrasse and Mill Gastroplasty (M&M): Midterm Results.

BACKGROUND: The Magenstrasse and Mill gastroplasty (M&M) is a gastric restrictive procedure without band or stomach resection. Short-term evaluation of the laparoscopic procedure showed low morbidity and satisfactory results on weight loss. Evidence of the validity of the technique in the longer term is scarce. METHODS: Data from patients who underwent M&M procedure from May 2012 to September 2015 were retrospectively reviewed. Preoperative clinical characteristics and data up to 4 years after operation were analyzed. RESULTS: A total of 132 patients were included in this study with a mean age of 46 ± 13.4 years. The mean body mass index (BMI) at the time of procedure was 43 ± 4.5 kg/m2. Mean percentage of excess weight loss (%EWL) was 67, 67, 58, and 57% at 1, 2, 3, and 4 years, respectively. The remission rate for diabetes was 36%. About half of the insulin-dependent patients could stop their insulin treatment. Hypertension was resolved in 33.8% of the patients after 4 years. Incidence of vitamin and mineral deficiency was low throughout the study period, less than or equal to 3% for vitamin B12 and 1% for ferritin. Incidence of gastroesophageal reflux did not exceed 15% during the study. Over 75% of the patients reported a good or very good quality of life following the surgery. CONCLUSION: These results confirm the validity of M&M as a bariatric procedure. The low incidence of vitamin deficiencies and gastroesophageal reflux might be the important asset of M&M over other existing techniques.

Endovascular stent-graft for thoracic aorta aneurysm caused by Salmonella.

We describe the placement of an endovascular stent-graft in a patient with mycotic aneurysm of the descending thoracic aorta caused by Salmonella. Endovascular grafting combined with antibiotic therapy in thoracic mycotic aneurysms might represent an alternative to conventional surgery in patients with high operative risk.

Initial experience of single-port surgery assisted by percutaneous instruments for gastric bypass: a combination of safety and minimally invasive surgery.

BACKGROUND: We present here the first reported cases of patients undergoing gastric bypass with a hybrid technique that involves a new concept of percutaneous instruments and provides the advantages of minimally invasive single-port surgery while maintaining the triangulation, safety, and timing of operative procedures. METHODS: This was a prospective pilot study of eight patients selected for gastric bypass between December 2011 and January 2012 and treated by a technique that combined single SSL port and percutaneous surgical set PPS. We performed hand-sewn gastrojejunostomy in all cases. We analyzed preliminary results at 1 month and focused on the feasibility of the technique, duration of surgery, perioperative complications, and cosmetic results. The Ethics Committee of our institution approved this study and we obtained the informed consent of each patient. RESULTS: We completed the procedure successfully in all patients. No conversions to laparotomy or classic laparoscopy were required. The average time of surgery was 112 min (85-155). Length of hospital stay was 4 days (3-5). One patient was re-admitted on the seventh postoperative day for gastrointestinal bleeding from the gastrojejunostomy suture and treated by endoscopic clipping. Residual scars were less than 2 cm for the single midline port and 2 mm for the percutaneous instruments. CONCLUSIONS: This new technique combines the advantages of single-port surgery with the safety of conventional laparoscopy by using percutaneous instruments and leaves minimal scarring. It is likely that the use of percutaneous instrumentation will become widespread in all areas of laparoscopic surgery.

Recurrent left colonic diverticulitis episodes: more severe than the initial diverticulitis?

BACKGROUND: Until recently, it was accepted that the rate of complications and failure of medical therapy were higher during recurrent episodes of diverticulitis. New data and new interpretation of older studies have challenged this opinion. The aim of the present study was to determine whether recurrent diverticulitis in comparison with the initial episode has a different short-term outcome after medical or surgical treatment. METHODS: This was a retrospective cohort study of 271 consecutive patients admitted for diverticulitis confirmed by computed tomography (CT) between 2001 and 2004. Altogether 202 patients had an initial episode (group I), and 69 had recurrent diverticulitis (group R). A total of 20 clinical and 15 radiologic parameters were analyzed and compared between the two groups, including need for surgery, clinical presentation at admission, response to treatment, complications, laboratory parameters, and pathologic CT features (colonic wall thickening, abscess, pneumoperitoneum, free intraperitoneal fluid). An unpaired Student's t-test and Fisher's and Wilcoxon's tests were applied for statistical analysis. RESULTS: None of the clinical or radiologic parameters was statistically different between the two groups. Regarding surgery, 15.8% of the group I patients needed surgery at admission compared to 5.8% in group R (p = 0.04). Conservative treatment failure was similar in the two groups (10.7% vs. 10.0%; p = 0.84). There was 3% mortality at 30 days in group I compared to 0% in group R. CONCLUSIONS: Recurrent episodes of diverticulitis do not lead to more complications and more conservative treatment failure. Moreover, surgery at admission was less frequent among patients who presented with a recurrence.

Esophageal leaks repaired by a muscle onlay approach in the presence of mediastinal sepsis.

BACKGROUND: Nineteen patients were evaluated after closure of intrathoracic esophageal leaks by a pediculated muscle flap onlay repair in the presence of mediastinal and systemic sepsis. METHODS: Intrathoracic esophageal leaks with mediastinitis and systemic sepsis occurred after delayed spontaneous perforations (n = 7) or surgical and endoscopic interventions (n = 12). Six patients presented with fulminant anastomotic leaks. Seven patients had previous attempts to close the leak by surgery (n = 4) or stenting (2) or both (n = 1). The debrided defects measured up to 2 x 12 cm or involved three quarters of the anastomotic circumference and were closed either by a full thickness diaphragmatic flap (n = 13) or a pediculated intrathoracically transposed extrathoracic muscle flap (n = 6). All patients had postoperative contrast esophagography between days 7 and 10 and an endoscopic evaluation 4 to 6 months after surgery. RESULTS: There was no 30-day mortality. During follow-up (4 to 42 months), 16 patients (84%) revealed functional and morphological restoration of the esophagointestinal integrity without further interventions. One patient required serial dilatations for a stricture, and 1 underwent temporary stenting for a persistent fistula; both patients had normal control endoscopy during follow-up. A third patient requiring permanent stenting for stenosis died from gastrointestinal bleeding due to stent erosion during follow-up. CONCLUSIONS: Intrathoracic esophageal leaks may be closed efficiently by a muscle flap onlay approach in the presence of mediastinitis and where a primary repair seems risky. The same holds true for fulminant intrathoracic anastomotic leaks after esophagectomy or other surgical interventions at the gastroesophageal junction.
