Laparoscopic total gastrectomy
A multimodality approach remains the only potential treatment for advanced gastric cancer. Oncological outcomes seem to be equivalent either in open surgery or in minimally invasive surgery. Therefore, laparoscopic gastric resection is expanding in expert centers.
The authors present a clinical case of a 70-year-old woman with no relevant clinical past. She presented with a 1-month complaint of epigastric pain and melena. She underwent an upper endoscopy, which showed an ulcerated gastric lesion at the lesser curvature. Biopsy revealed a poorly cohesive gastric carcinoma with signet ring cells. Thoraco-abdominal-pelvic CT-scan revealed a thickening of the gastric wall associated with multiple perigastric and celiac trunk lymph nodes. She was proposed for perioperative chemotherapy. On the restaging CT-scan, there was no evidence of disease progression and therefore she underwent a laparoscopic radical total gastrectomy.
The benefits of minimally invasive surgery, combined with the increasing evidence of oncological results overlapping with open surgery, have contributed to the progressive implementation of laparoscopic surgery in the treatment of malignant gastric pathology.

Laparoscopic revision of Nissen fundoplication to Roux-en-Y gastric bypass
Introduction: Obesity is a known etiological factor for gastroesophageal reflux disease (GERD) and is also a growing public health concern. Although Nissen fundoplication is a highly effective technique to treat GERD, it may fail in obese patients. Roux-en-Y gastric bypass provides excellent long-term control of GERD symptoms with the additional benefit of weight loss.
Clinical case: A 57-year-old woman underwent a laparoscopic Nissen fundoplication for GERD (BMI 30.0 Kg/m2) with excellent outcomes during the first postoperative year in 2011. Two years later, GERD symptoms recurred, and her weight increased progressively (BMI of 36.0 Kg/m2). The patient was proposed to a laparoscopic conversion of Nissen fundoplication to a Roux-en-Y gastric bypass. The procedure was uneventful, and the patient was discharged on postoperative day 4. One year later, she remained asymptomatic, off antacids medication, and with her weight decreased to 63.5Kg which corresponded to a BMI of 25.4 Kg/m2.
Discussion/conclusion: Roux-en-Y gastric bypass successfully reduces GERD symptoms by diverting bile away from the esophagus, decreasing acid production in the gastric pouch, therefore limiting the amount of acid reflux and by promoting weight loss decreases abdominal pressure over the lower esophageal sphincter and esophageal hiatus. In obese patients (BMI>35) with GERD, Roux-en-Y gastric bypass seems to be the most effective and advantageous treatment since it provides control of GERD symptoms with the additional benefit of weight loss. In patients who have previously undergone anti-reflux surgery, bariatric surgery can be technically demanding. However, if performed by high-volume surgeons in high-volume centers, it is perfectly feasible with low morbidity and excellent results.

Laparoscopic right colectomy: bottom-to-up approach with intracorporeal anastomosis
Introduction
Laparoscopic right colectomy (LRC) has become a well-established technique in colon cancer treatment achieving the same degree of radicality as open colectomy with the advantages of minimal invasion. A medial-to-lateral approach is the standard technique, but the bottom-to-up approach, with intracorporeal anastomosis (BTU), has recently gained popularity among surgeons.
Clinical case
The authors report the case of a 70-year-old male patient with persistent abdominal discomfort and a change in bowel habits. Preoperative staging revealed an adenocarcinoma at the hepatic flexure of the colon with no metastatic disease. The patient was proposed for a laparoscopic right colectomy.
A bottom-to-up approach was performed by opening an avascular plane posterior to the right mesocolon, creating a mesenteric route cranially along Gerota’s fascia until the duodenum and liver have been exposed. A side-to-side ileocolic intracorporeal stapled anastomosis was fashioned. The procedure and postoperative recovery were uneventful.
Discussion/Conclusion
LRC using a BTU approach is a feasible and safe alternative to the conventional medial-to-lateral approach. The main advantages are a short learning curve and an easy access to the retroperitoneal space with direct visualization and protection of retroperitoneal structures. The performance of an intracorporeal anastomosis offers the advantage of a smaller extraction incision, lower wound-related complications, and fast recovery.
