Decision analysis model of incisional hernia after open abdominal surgery

Background The incidence rate of incisional hernias after open surgery has been reported to be higher than that of port site hernias after laparoscopic surgery. No studies have compared the costs for the health care system in treating those two types of hernia. Methods A systematic review was conducted to obtain the baseline data, and a decision analysis model was created to simulate the occurrence and recurrence of incisional and port site hernias. Results The overall risk of having incisional hernias was eight-times higher than that of having port site hernias (7.4% vs 0.9%). A cost savings of ￡93 per patient can be generated for the health care system in the UK. Similar results were obtained for Germany, Italy and France. Conclusions The additional treatment costs for incisional hernia should be taken into account when the costs of a surgery performed by open approach are compared with by laparoscopy.     

Elective laparoscopic-assisted colectomy for sigmoid diverticulitis.

OBJECTIVES: The aim of this study was to evaluate the safety and effectiveness of laparoscopic-assisted sigmoid colectomy for diverticulitis and to assess its postoperative advantages. METHODS: From 1999 to 2001, 5 patients were selectively operated on with a laparoscopic-assisted procedure for uncomplicated sigmoid diverticulitis. In the preceding period (September 1997 through December 1998), 4 patients underwent open procedures for the same pathology. The surgical indication with the same criteria was restrictive: at least 2 acute episodes had occurred that were treated with hospital admission and that were separated by an adequate period (2 months) of medical therapy. RESULTS: No conversions of laparoscopy to an open procedure were necessary. Age, sex, weight, morbidity, and mortality were similar between the 2 groups. Operative time was 180 minutes for laparoscopy and 120 minutes for laparotomy. Postoperative resumption of peristalsis was 24 hours versus 4 days, resumption of alimentation was on the second postoperative day versus the fifth postoperative day, and hospital stay was 7 days versus 12 days for laparoscopy and laparotomy, respectively. CONCLUSION: This study shows the feasibility and the advantages of elective laparoscopic-assisted colonic resection for uncomplicated sigmoid diverticulitis. The advantages of the laparoscopic approach are the lower need for analgesics and the more precocious ambulation, canalization, resumption of alimentation, and the shorter hospital stay.

Laparoscopic Medial-to-lateral Colon Dissection: How and Why

Laparoscopic colectomy is a difficult procedure with a long learning curve. We describe in this study our technique for right- and left-sided laparoscopic medial-to-lateral colectomy. The medial approach involves division of the vascular pedicle first, followed by mobilization of the mesentery toward the abdominal wall, and finally freeing of the colon along the white line of Toldt. This approach allows immediate identification of the plane between the mesocolon and the retroperitoneum and renders the dissection fast and safe. Our series of 50 consecutive laparoscopic colectomies supports this concept. We believe that surgeons familiar with this technique will have an important tool in their armamentarium to circumvent some of the challenges of laparoscopic colectomy.     

Technical Considerations in Laparoscopic Fundoplication

Gastroesophageal reflux disease (GERD) is a common disease and can be successfully treated by laparoscopic fundoplication. This article describes the technique of laparoscopic surgery for GERD with a focus on operative pitfalls.     

腹腔镜高选择性迷走神经切断术联合Nissen胃底折叠术:效果如何?——腹腔镜Nissen迷走神经切断术治疗胃食管返流

背景：Nissen胃底折叠术（Nissen fundoplication，NF）已不是治疗胃食管返流性疾病（gastroesophageal reflux disease，GERD）的唯一、有效的方法。对于能降低胃酸的手术方式来讲，如高选择性迷走神经切断术（highly selective vagotomy，HSV），也不仅仅是一种辅助治疗方法。对高选择性迷走神经切断术联合Nissen胃底折叠术（Nissen fundoplication with highly selective vagotomy，NFHSV）治疗GERD的作用目前尚无完整的评价。方法：2003年6月～2005年6月8例女性病人接受NFHSV，8例均有6个月GERD病史，经药物治疗症状无缓解，有餐前痛、消化性溃疡或严重的胃炎。平均随访时间12个月，术前、术后进行烧心严重程度评分测定（heart burn severity score，HSS）。结果：平均手术时间110min，无手术并发症。1例术后须用质子泵抑制剂，术后经戒烟5个月后停药。8例术后症状和烧心严重程度评分测定有明显改善。结论：NFHSV是有效的联合手术方式，尚需要进一步的研究证实这一联合术式的完全有效性和安全性。     

Patient comprehension and recall of laparoscopic surgery and outcomes in a non-English speaking population.

BACKGROUND AND OBJECTIVES: The purpose of this study was to determine patient recall and comprehension after laparoscopic appendectomy in an underserved population. Laparoscopic surgery can lead to diagnostic uncertainty secondary to poor recall and variable port placement. METHODS: After institutional review board approval, we identified a cohort of patients who underwent laparoscopic appendectomy from 2000 to 2004 at a single institution. We then attempted to contact the patients to conduct a 10-question telephone survey, which determined whether the patient spoke English or Spanish as a primary language, ethnicity, educational level, and questions about recall of perioperative events and diagnoses. If we could not reach the patient, we tried to call back on 2 different occasions. RESULTS: Between 2000 and 2004, 186 patients underwent laparoscopic appendectomy. Of these, 65% were Hispanic. We found that only 17% of these patients returned for a postoperative visit. Only 19.3% could be contacted by phone. Forty-seven percent of the patients contacted by phone spoke Spanish exclusively. Overall 92% of patients contacted knew what operation they had, and gave their correct diagnosis. CONCLUSIONS: The low percentage of patients available to follow-up makes this study statistically insignificant. However, we believe that fact in itself is important. In Southwestern states, we see a large migrant population. This highlights the need to communicate effectively with the patients at the time of surgery, which we speculate we did based on the percentage of patients that knew their diagnosis.

Small Bowel Obstruction Secondary to Intragastric Erosion and Migration of A Gastric Band

We describe what we believe to be the first reported case of intragastric erosion and migration to the jejenum of a laparoscopically inserted gastric band, 3 months after the original bariatric surgery was performed. This had caused ulceration and necrosis of the small bowel as the tension in the port tubing had caused the bowel to become concertinaed over it and resulted in a cheese-wire effect through the jejunal convolutions. As bariatric surgery becomes more common, patients with complications of their procedure may present to the general surgeon as an emergency. We recommend early intervention in patients with gastric erosion.
