Laparoscopic Fundoplication with or Without Pyloroplasty in Patients with Gastroesophageal Reflux Disease After Lung Transplantation: How I Do It

Introduction  

Several studies have confirmed that gastroesophageal reflux disease (GERD) in lung transplant patients is a risk factor for the development and progression of bronchiolitis obliterans syndrome (BOS), a form of rejection after lung transplantation. Moreover, numerous reports indicate that surgical correction of GERD may control the decline in lung function characteristic of BOS. Although laparoscopic fundoplication is an accepted treatment option for these patients with GERD, the surgical technique, which often includes a laparoscopic pyloroplasty, has not been standardized.     

Distal Pancreatectomy and Splenectomy: A Robotic or LESS Approach

Introduction:The role and application of robotic surgery are debated, particularly given the expansion of laparoscopy, especially laparoendoscopic single-site (LESS) surgery. This cohort study was undertaken to delineate differences in outcomes between LESS and robotic distal pancreatectomy and splenectomy.Methods:With Institutional Review Board approval, patients undergoing LESS or robotic distal pancreatectomy and splenectomy from September 1, 2012, through December 31, 2014, were prospectively observed, and data were collected. The results are expressed as the median, with the mean ± SD.Results:Thirty-four patients underwent a minimally invasive distal pancreatectomy and splenectomy: 18 with robotic and 16 with LESS surgery. The patients were similar in sex, age, and body mass index. Conversions to open surgery and estimated blood loss were similar. There were two intraoperative complications in the group that underwent the robotic approach. Time spent in the operating room was significantly longer with the robot (297 vs 254 minutes, P = .03), although operative duration (i.e., incision to closure) was not longer (225 vs 190 minutes; P = .15). Of the operations studied, 79% were undertaken for neoplastic processes. Tumor size was 3.5 cm for both approaches; R0 resections were achieved in all patients. Length of stay was similar in the two study groups (5 vs 4 days). There was one 30-day readmission after robotic surgery.Conclusions:Patient outcomes are similar with LESS or robotic distal pancreatectomy and splenectomy. Robotic operations require more time in the operating room. Both are safe and efficacious minimally invasive operations that follow similar oncologic principles for similar tumors, and both should be in the surgeon''s armamentarium for distal pancreatectomy and splenectomy.     

How I Do It: Laparoscopic Paraesophageal Hernia Repair

Introduction

Paraesophageal hernias are usually complex anatomic abnormalities of the upper gastrointestinal tract capable of causing symptoms and complications including death. Furthermore, they affect patients who are usually older and have other comorbidities. Preferred treatment approach has evolved over time, with laparoscopic repair being the current preferred technique as it causes less hemodynamic changes and is better tolerated than open repairs.

Technique

In this report, we describe our technique for laparoscopic paraesophageal hernia repair. The most salient technical aspects of this procedure include reduction of the stomach below the diaphragm, circumferential dissection and excision of the hernia sac, closure of the crural defect with our without the addition of mesh, and fundoplication to prevent reflux.

Conclusion

While this procedure has a low morbidity risk and short hospital stay, anatomic recurrence is frequent even when performed by experienced surgeons.     

Laparoscopic Morgagni Hernia Repair: How I Do It

Surgical repair of Morgagni hernias is recommended given their historically high risk of incarceration. Traditionally, such repair has been undertaken via laparotomy or thoracotomy or more recently, thoracoscopically or laparoscopically using mesh. Here, we describe a laparoscopic approach to the management of Morgagni hernias achieving a primary tissue repair without mesh implantation. This technique allows for the general benefits of minimally invasive surgery, such as less postoperative pain, reduced wound complications, decreased duration of the hospital stay, as well as offering an alternative to mesh implantation and its associated potential complications.     

How I Do It: Hybrid Laparoscopic and Robotic Pancreaticoduodenectomy

Minimally invasive pancreatic resections remain technically challenging. Distal pancreatectomy has been embraced at multiple centers as an acceptable minimally invasive technique in selected patients. In contrast, minimally invasive pancreaticoduodenectomy has not achieved broad acceptance, partly due to technical challenges. We detail a minimally invasive technique that utilizes both laparoscopic and robotic approaches which capitalizes on the advantages of each. Our early results have encouraged the continued development of this minimally invasive pancreatic surgery program. This hybrid technique may be an approach that is useful for surgeons striving to adopt the advantages of minimally invasive surgery for their patients.     

Comparison of Laparoscopic Distal Pancreatectomy with or without Splenic Preservation

Laparoscopic distal pancreatectomy (LDP) has gained large popularity in recent years, although the choice of whether to preserve the spleen has remained inconsistent. The aim of our study was to report our experiences with LDP and to provide evidence for the safety of the operative technique and an evaluation index of splenic function. We retrospectively evaluated all LDPs performed at our institution between March 2008 and February 2012. Cases were divided into a laparoscopic spleen-preserving distal pancreatectomy (LSPDP) group (n?=?14) and an LDP with splenectomy (LDPS) group (n?=?19). Parametric and nonparametric statistical analyses were used to compare perioperative and oncologic outcomes. Demographic characteristics, operating time, length of stay, estimated blood loss, transfusion requirement, pathologic diagnosis, and complication rate were similar between groups. Patients who underwent LDPS tended to have larger masses and lower pancreatic fistula rates, but these differences were not significant. White blood cell (WBC) counts were significantly higher in the LDPS group than in the LSPDP group on postoperative days 1 and 7. To avoid splenectomy-associated complications, preservation of the spleen and especially the splenic vessels are preferred. This procedure can be performed safely and feasibly. Lower postoperative WBC counts may imply better splenic function.     

How I Do It: Laparoscopic Heller Myotomy with Toupet Fundoplication for Achalasia

Achalasia, an esophageal motility disorder characterized by aperistalsis and failure of lower esophageal sphincter (LES) relaxation, is most effectively treated by surgical ablation of the LES. In this report, we describe our technique of laparoscopic extended Heller myotomy with Toupet partial posterior fundoplication. The technical details of this procedure include careful division of the longitudinal and circular muscle fibers of the LES anteriorly, including extension of the myotomy 3 cm distal to the esophagogastric junction onto the gastric cardia. The Toupet procedure, involving a posterior wrap of the gastric fundus which is secured to both edges of the myotomy as well as to the crura of the hiatus, is added to prevent post-myotomy gastroesophageal reflux. From a recently published report, mean dysphagia scores remained low (3 out of 10 severity on a visual analog scale) and symptoms of reflux were reported minimally in a series of 63 patients followed for a median of 45 months. This technique provides excellent and durable relief of dysphagia associated with achalasia while minimizing post-myotomy acid reflux symptoms.     

Multiple Proinsulin-Secreting Tumors of the Pancreas Treated by Laparoscopic Distal Pancreatectomy and Splenectomy

Background  Patients with pancreatic tumors that induce hypoglycemia present with a myriad of symptoms. Laboratory testing can frequently result in data challenging to the clinician to confirm the biochemical diagnosis. Proinsulin, in addition to insulin levels, may be essential in evaluating and diagnosing an insulinoma. Methods  The objective of this case report is to demonstrate the potential importance of proinsulin levels in the evaluation of tumor-induced hypoglycemia. We report a 49-year-old woman with an unusual clinical presentation. Unlike many patients with tumor-induced hypoglycemia, her fasting glucose levels were fairly unimpressive, her insulin levels were undetectable during a prolonged fast, and she had elevated proinsulin levels. Results  The inpatient fast was remarkable for levels of serum glucose 53 mg/dl or higher, a serum insulin <2 uIU/ml, C-peptide 0.7–1.1 (nl 0.8–3.1 ng/ml), and proinsulin 29.2–36.8 pmol/l (nl ≤ 18.8 pmol/l). CT scanning of the abdomen revealed multiple pancreatic lesions. A laparoscopic distal pancreatectomy led to the removal of multiple neuroendocrine tumors, which stained only for proinsulin and not for other pancreatic tumor markers. Postoperatively, she normalized her biochemical serum studies and has remained symptom-free 2 years later. Conclusions  The measurement of proinsulin plays an important part in the diagnostic workup of neuroendocrine tumors causing hypoglycemia. These potentially malignant tumors can be treated adequately with minimally invasive surgery.     

Spleen-preserving Distal Pancreatectomy with Excision of Splenic Artery and Vein: A Case-matched Comparison with Conventional Distal Pancreatectomy with Splenectomy

Background The value of spleen preservation during distal pancreatectomy (DP) still remains controversial. Spleen-preserving DP with excision of the splenic artery and vein is a simplified technique for spleen preservation. The aim of this study was to compare the postoperative course of DP with or without splenectomy. Patients and Methods From 1990 to 2005, 38 consecutive patients with benign or low-grade malignant disease underwent a spleen-preserving DP operation with excision of the splenic artery and vein (Conservative Group). They were compared with 38 patients who underwent conventional DP with splenectomy over the same time period (Splenectomy Group) and who had been matched for age, American Society of Anesthesiologists (ASA) score, and pathological diagnosis. Postoperative courses were analyzed and compared between the Conservative Group and Splenectomy Group. Results Spleen preservation was effective in 36 of the 38 attempts (95%). Postoperative complications – in particular, infectious intra-abdominal complications – were significantly higher in the Splenectomy Group (34 and 18%, respectively) than in the Conservative Group (13 and 3%, respectively) (P = 0.03 and P = 0.02, respectively). The length of the surgery, perioperative blood loss or transfusions, perioperative mortality and length of hospital stay did not differ between the two groups. Univariate analysis showed that splenectomy was the only risk factor for postoperative complication. Conclusions Spleen-preserving DP with excision of the splenic artery and vein is a fast, safe and effective procedure associated, in this series, with a reduction of postoperative complications relative to conventional DP with splenectomy. This technique should be considered in patients with benign or low-grade malignant disease of the pancreas. The authors declare that there are no competing interests.     

Robot-Assisted Spleen-Preserving Laparoscopic Distal Pancreatectomy

Background  

Spleen-preserving laparoscopic distal pancreatectomy would be an ideal approach for benign and borderline malignant tumors in the distal pancreas.1 However, this procedure requires advanced surgical experience and technique because of the disadvantages of conventional laparoscopic surgery.2

Incremental Hemodialysis: How I Do It

Incremental hemodialysis (incrHD) is not widely used nor is it well understood. In addition, and perhaps with more impact, governmental regulations in the United States and their consequential influences on dialysis provider organizations have made the practice of incrHD more difficult than traditional thrice weekly in‐center HD. IncrHD is critically dependent on the amount of residual kidney function (RKF) as well as the individualized goals of end‐stage renal disease (ESRD) management. RKF has to be assessed frequently and dialysis adjusted accordingly. Home HD lends itself to an incremental approach more so than in‐center HD. This may be due to more experience of the provider, more knowledge of the therapy by the patient and family, the availability of dialysis platforms conducive to incrHD, and/or that its less onerous regulation by the government. I have had a long and successful experience performing incremental dialysis (both peritoneal and hemodialysis) and share here my practice strategies and approaches for incrHD.

Laparoscopic Total Fundoplication for Gastroesophageal Reflux Disease. How I Do It

Introduction

A laparoscopic fundoplication is considered today the procedure of choice for the treatment of gastroesophageal reflux disease (GERD).

Discussion

Several eponyms are used in the literature to denote different antireflux operations: Nissen, Nissen-Rossetti, Toupet, Lind, Guarner, Hill, and Dor. We feel that it is more important to focus on the technical elements which make a fundoplication effective and long lasting. The type of fundoplication (total vs. partial) is tailored to the quality of esophageal peristalsis as documented by the preoperative manometry. In the USA, a partial fundoplication is chosen only for patients with very impaired or absent esophageal peristalsis.

Conclusion

This article describes the technique of laparoscopic total fundoplication for GERD. Partial fundoplication is performed following the same technical elements as the total fundoplication. A 240° to 270° wrap rather than a 360° wrap is performed.
