A difficult laparoscopic cholecystectomy that requires conversion to open procedure can be predicted by preoperative ultrasonography.

A prospective study was conducted from March 1999 to April 2000 that included 73 patients who underwent elective laparoscopic cholecystectomy for uncomplicated gallstone disease. The study was conducted at one surgical unit in the Department of Surgery and Department of Radio-diagnosis and one surgical unit in the Department of Surgery, Maulana Azad Medical College and the associated Lok Nayak Hospital, which is the largest referral hospital in northern India and is located in the capital of India. A preoperative ultrasound was performed just prior to surgery, and 4 ultrasonographic parameters were analyzed. namely gallbladder wall thickness, contracted gallbladder, impaction of gallstones at the neck of the gallbladder, and common bile duct stones. The surgical findings were objectively graded as difficult or easy laparoscopic cholecystectomy according to 5 operative parameters, namely total time taken for the surgery, time taken to dissect gallbladder bed, spillage of stones, tear of gallbladder during dissection, and conversion to the open procedure. Of the 73 cases, 17 (23.3%) were conversions to the open procedure. Of the 21 (28.76%) cases predicted to be difficult, 17 (23.3%) were technically difficult, of which 13 (17.8%) were converted to the open procedure. Of the 52 (71.23%) cases predicted to be easy on ultrasonography, only 7 (9.38%) were found to be difficult on surgery, of which only 4 (5.48%) had to be converted to the open procedure. Based on our results, we conclude that preoperative ultrasonography is of great value in selecting patients preoperatively for laparoscopic cholecystectomy and minimizing complications and conversion to the open procedure.

A financial analysis of laparoscopic and open cholecystectomy

Laparoscopic cholecystectomy (LC) is now the method of choice in treatment of symptomatic gallstone disease. Despite its rapidly growing popularity, comparative costs of this new method and open cholecystectomy (OC) remain unclear. The most outstanding feature of laparoscopic cholecystectomy is the period of short recovery. In Sweden the social insurance office documents sick leave period, sickness allowance, as well as diagnosis and therefore provides a reliable basis for an economic analysis. The purpose of this study was to estimate the hospital cost and costs due to sick leave in a series of patients operated on with elective cholecystectomy using the two methods. In each group 50 consecutive patients were studied retrospectively. The total hospital cost was 10% lower in the laparoscopy group—$1,864 as compared to $2,030 per patient in the OC group. Median number of days off work was 14 after LC and 35 days after open surgery, which corresponds to a median sickness allowance of $516 per patient (LC) compared to $1,424 (OC). Laparoscopic cholecystectomy is more cost-effective than open cholecystectomy mainly due to a reduced sick leave period.     

The use of laparoscopic subtotal cholecystectomy for complicated cholelithiasis

BACKGROUND: The risk of damage to the bile duct and structures in the hilum of the liver is significant when Calot's triangle cannot be safely dissected during laparoscopic cholecystectomy, and conversion to an open procedure often is performed. This is more common during emergency surgery, but may not render the procedure any easier. Traditionally, open subtotal cholecystectomy was performed, but with the advent of laparoscopic surgery, this has fallen from favor. The authors report their experience using laparoscopic subtotal cholecystectomy to avoid bile duct injury and conversion in difficult cases. METHODS: Laparoscopic subtotal cholecystectomy, performed when the cystic duct cannot be identified safely, consists of resecting the anterior wall of the gallbladder, removing all stones, and placing a large drain into Hartmann's pouch. The notes for all patients who underwent a laparoscopic subtotal cholecystectomy between 1 September 2001 and 31 December 2004 were retrospectively analyzed. RESULTS: Subtotal cholecystectomy was performed in 26 cases including 13 emergency and 13 elective procedures. The median age of the patients (15 women and 11 men) was 68 years (range, 36-86 years). The indications were severe fibrosis in 16 cases, inflammatory mass or empyema in 8 cases, and gangrenous gallbladder or perforation in 2 cases. The median postoperative inpatient stay was 5 days (range, 2-26 days). Five patients underwent postoperative endoscopic retrograde cholangiopancreatography: four for persistent biliary leak and one for a retained common bile duct stone. One patient required laparotomy for subphrenic abscess, and one patient (American Society of Anesthesiology [ASA] grade 4, presenting with biliary peritonitis) died 2 days postoperatively. One patient required a subsequent completion laparoscopic cholecystectomy for a retained gallstone. One patient had a chest infection, and two patients experienced port-site hernias. CONCLUSIONS: Laparoscopic subtotal cholecystectomy is a viable procedure during cholecystectomy in which Calot's triangle cannot be dissected. It averts the need for a laparotomy.     

Techniques for difficult cases of laparoscopic cholecystectomy

Our basic techniques for the management of difficult cases of laparoscopic cholecystectomy (LC) are presented in this article. If access to Calot's triangle cannot be gained safely, dissection should be started at the fundus or body of the gallbladder (GB), rather than the neck (fundus-first method). In cases with a short and wide cystic duct, a transfixing suture should be applied for ligation instead of clipping. EndoGIA is useful for ligating and transecting this case to avoid a subsequent stricture caused by normal method of ligation. Intraoperative cholangiography should be performed near the neck of the GB in cases in which orientation is lost during dissection. More dissection should be performed in the direction of the junction of the bile ducts after orientation is regained. In cases with GB filled with stones accompanied by severe fibrosis, part of the GB is incised to remove the stones and expose the lumen of the GB. Confluence stones can be removed by placing an incision on the GB side of the junction of the duct. The incised part is closed with suture. A cystic tube (C-tube) is placed in the common bile duct through the cystic duct for decompression. In more difficult cases in which dissection cannot be started safely at any location, the body and the fundus of the GB are excised, and a drain is placed at the neck of the GB. Dissection can be carried out from the main surgeon's or the assistant's side depending on the situation, and cooperation between the two surgeons is mandatory to achieve safe LC in difficult cases. When performing the LC, one must have a low threshold for converting to open surgery if injuries cannot be managed safely.     

Predicting conversion of laparoscopic cholecystectomy for acute cholecystitis.

BACKGROUND AND OBJECTIVES: Laparoscopic cholecystectomy can be safely performed in patients with acute cholecystitis. However, the rate of conversion to open cholecystectomy remains higher when compared with patients with chronic cholecystitis. Preoperative clinical or laboratory parameters that could predict the need for conversion may assist the surgeon in preoperative or intraoperative decision making. This could have cost-saving implications. METHODS: A retrospective review of 46 patients undergoing laparoscopic cholecystectomy for acute cholecystitis was performed. Records were assessed for preoperative clinical, laboratory and radiographic parameters on admission. Temperature and laboratory parameters were also recorded prior to surgery after an initial period of hospitalization that included intravenous antibiotics. The effect of admission and preoperative parameters as well as the trend in these parameters prior to surgery upon the rate of conversion to open cholecystectomy was assessed. RESULTS: Ten patients (22%) required conversion to open cholecystectomy. Conversion was required more often in males (43%) when compared with females (4%) (p=0.003). Conversion rate was 30% in patients with increased wall thickness by ultrasound compared with 12% for patients without wall thickening (p=ns). No admission or preoperative laboratory values predicted conversion. The trend in the patient's temperature (p=0.0003) and serum LDH value (p=0.043) predicted the need for conversion to open surgery. CONCLUSIONS: Preoperative prediction of the need for open cholecystectomy remains elusive. Male patients and patients with rising temperature and LDH levels while on intravenous antibiotics require conversion at increased frequency. However, the benefits of laparoscopic cholecystectomy warrant an attempt at laparoscopic removal in most patients with acute cholecystitis.

Risk factors for conversion of laparoscopic cholecystectomy to open cholecystectomy

Background Conversion to open cholecystectomy is still required in some patients. The aim of this study was to evaluate preoperative factors associated with conversion to open cholecystectomy in elective cholecystectomy and acute cholecystitis.Methods The records of 1,804 patients who underwent cholecystectomy from May 1992 to January 2004 were reviewed retrospectively. The demographics and preoperative data of patients who required conversion to laparotomy were compared to those with successful laparoscopic cholecystectomy.Results Conversion to open cholecystectomy was needed in 94 patients (5.2%),of which 44 (2.8%) had no inflammation and 50 (18.4%) had acute inflammation of the gallbladder. Male gender, age older than 60 years, previous upper abdominal surgery, diabetes, and severity of inflammation were all significantly correlated with an increased conversion rate to laparotomy. Also, the conversion from laparoscopic to open cholecystectomy in acute cholecystitis patients was associated with greater white blood cell count, fever, elevated total bilirubin, aspartate transaminase, and alanine transaminase levels, and the various types of inflammation.Conclusions None of these risk factors were contraindications to laparoscopic cholecystectomy. This may help predict the difficulty of the procedure and permit the surgeon to better inform patients about the risk of conversion from laparoscopic to open cholecystectomy.     

Giant gallstone performed by emergency laparoscopic cholecystectomy

INTRODUCTIONGallstone disease is very common, but the gallstone bigger than 5 cm in diameter is very rare. It is very challenging to be removed by laparoscopic cholecystectomy (LC) and poses extra difficulty in emergency.PRESENTATION OF CASEA 70-year-old man complained of abdominal pain in the right upper quadrant with fever of 38 °C for two days. Abdominal ultrasound indicated acute cholecystitis and a single, extremely large gallstone (95 mm × 60 mm × 45 mm). Emergency laparoscopic cholecystectomy was performed successfully.DISCUSSIONGallstone over 5 cm in diameter is very rare. LC will be very difficult for these cases, especially for the emergency cases. Emergency laparoscopic cholecystectomy can be successfully performed with clear exposure of the anatomy of the Calot's triangle. To the best of our knowledge, such giant gallstone has been rarely reported.CONCLUSIONWe have proven that for the rare giant gallstone about 10 cm in size, LC is a feasible option if the anatomy of the Calot's triangle can be clearly exposed; otherwise, open cholecystectomy is a safe choice.

目的对比合并肝硬化的胆囊结石症行腹腔镜胆囊切除与开腹胆囊切除术的疗效。方法回顾性分析我院1999～2004年25例合并肝硬化的症状性胆囊结石患者,其中13例行LC,12例行OC。结果13例LC患者1例出现肺部感染;12例OC患者术后切口感染1例,肺部感染3例,切口渗液4例,尿路感染3例;术中出血量LC组明显少于OC组P<0.0.5;术后住院时间LC组明显短于OC组P<0.0.5。结论LC治疗合并肝硬化的症状性胆囊结石症,具有明显的优点,与OC相比,LC手术时间短,手术出血量少,术后并发症发生率低,同时缩短了住院时间,在肝硬化ChildA鄄B级病人中安全可靠。     

Comparison of serum C-reactive protein concentrations for laparoscopic versus open cholecystectomy

In an attempt to quantify the difference in tissue damage between open cholecystectomy (OC) and laparoscopic cholecystectomy (LC), we have compared in a prospective manner the pre- and postoperative concentrations of serum C-reactive protein (CRP) in 17 patients undergoing LC and 13 patients undergoing OC. In addition, we measured the pre- and postoperative white blood cell counts (WBC), the postoperative body temperature, and the postoperative duration of hospitalization. There were no differences in the preoperative serum CRP concentrations—5.9±2.62 mg/l (mean±SD) for the LC group and 6.12±2.38 mg/l for the OC group.Serum CRP rose markedly following OC compared to that of patients who underwent LC (128.6±45.1 mg/l vs 26.8±10.5 mg/l) (P<0.001). There were also significant differences in the postoperative WBC count (14,000±2,900 cells for the OC group vs 10,600±3,000 cells for the LC group), the postoperative body temperature (37.5±0.3°C vs 37.0±0.3°C), and the postoperative hospital stay (5.5±1.5 days vs 1.9±0.9 days). There was no correlation between serum CRP concentrations and the other postoperative parameters.These results provide us with biochemical evidence supporting the clinical observation that LC is far less traumatic to the patient than OC.
