Hand Assisted Laparoscopic Splenectomy (HALS) in a Case of Primary Solitary Unilocular Gaint Splenic Hydatid.

Hydatid disease, a zoonotic parasitic infestation mainly caused by Echinococcus granulosus is a significant problem in endemic areas. Primary splenic hydatidosis is rare. A case is described in a 52 year male who presented with left upper quadrant swelling and pain. Ultrasonography of the abdomen revealed enlarged spleen with span of 14 cm with intraparenchymal cyst measuring 93.1mm x 92 3mm x83.3mm with approximate volume of 378.3 cc. CT scan of the abdomen showed spleen enlarged in size and measures 14.1cm with well defined cystic lesion of 10.1 x 9.2 cm.cyst shows internal serpentine structure suggestive of membranes with no calcification and no liver involvement. Hand assisted laparoscopic splenectomy (HALS) was performed.

Introduction: colorectal hand-assisted laparoscopy surgery is proposed as an alternative approach to standard laparoscopy in order to make the procedure easier and to maintain the advantages of minimally invasive surgery. The aim of this study was to analyze our initial experience in terms of intra-operative and short-term outcomes in patients with colorectal cancer. Methods: we analyzed 100 patients (51 females; mean age, 69 years; BMI, 24) operated on electively between July 2006 and January 2009. The indications for surgery were: adenocarcinoma of the right colon (31 cases), adenocarcinoma of the left colon (29 cases), adenocarcinoma of the rectum (21 cases), adenomatous polyp (15 cases), synchronous adenocarcinoma (2 cases) and adenocarcinoma of the transverse colon (2 cases). The procedures performed were: 38 right colectomies, 23 sigmoidectomies, 23 anterior resection, 12 left colectomies, 2 transverse colectomy, and 2 double colectomy. Results: The median size of the incision was 6.5 cm (95 per cent CI, 6-5) cm. Global operative time was 150 minutes (95 per cent C1, 140-180). Anterior resections were associated with a longer operative time: 190 minutes vs. 145 and 120 minutes for right and left colectomies respectively (p<0.005). The median loss of blood was 70 ml (IC95 per cent, 60-100). Five cases (5 per cent) required conversion with no cases in the last 55 patients. There were only 1 intraoperative complication which required conversion and there were not postoperative deaths. The median hospital stay was 3.5 (95 per cent CI, 3-4) days, and only 1 patient requiring re-admission. 26 per cent of the patients passed gas in the first postoperative day (median 2; 95 per cent CI, 1-2 days). The morbidity rate was 11 per cent (11 patients): wound infection, 5 cases; bleeding through drainage, 1 case; postoperative ileo, 5 cases...

Learning Curve for Laparoscopic Colorectal Surgery: Hand Assisted Laparoscopic Surgery (HALS) versus Conventional Laparoscopic Surgery (CLS)

Purpose: Laparoscopic colorectal surgery is technically demanding and needs a longer learning curve than open surgery. HALS (hand-assisted laparoscopic surgery) is a useful alternative to conventional laparoscopic surgery (CLS) because of its palpability and hand dissection. We compared the learning curves between HALS and CLS for colorectal surgery. Methods: A prospective study without randomization was conducted with the participation of two colorectal surgeons who had not experienced a laparoscopic colorectal operation. The collected data included operative features, oncologic outcomes, and early clinical outcomes. Fifty patients were enrolled in each group, the HALS group and the CLS group. Results: None of the operations converted to open surgery. The operative time was significantly shorter in the HALS group than in the CLS group (149.6+/-34.6 minutes versus 179.1+/-36.5 minutes, P<0.001). On a subgroup analysis of the operative time in the anterior resection, the operative time was consistent after the 13th operation in HALS group. However, in CLS group, there was a continuous fluctuation of the operative time until 25 cases. In regard to the oncologic outcome, the numbers of total harvested lymph nodes and the proximal and the distal margins in the anterior resection showed no statistical differences (P=0.400, P=0.908, and P=0.073, respectively). The early clinical results were similar in both groups. Conclusions: In the learning curve study, the HALS group had a shorter operative time and reached a learning curve plateau earlier than the CLS group. Other parameters, such as the oncologic results and the early postoperative clinical outcomes, showed no differences between the two groups.

Hand-assisted laparoscopic hepatectomy for hepatic hemangioma / 中国普通外科杂志

Objective To evaluate the feasibility, safety, and outcome of hepatectomy by hand-assisted laparoscopic surgery (Lapdisc system) in patients with hepatic hemangioma. Methods Eight patients with hepatic hemangioma underwent hand-assisted laparoscopic hepatectomy. Procedures included introduction of Lapdisc system, isolation of the liver from the ligments, occlusion of the hepatic porta, dissection of the hepatic parenchyma by harmonic scaple and removal of the samples. ResultsIn all patients, the hand-assisted laparoscopic hepatectomy were successfully performed. The operation time was(196.3?81.2)min. Blood loss was (307.5?224.7)ml, and postoperative hospital stay was (7.9?2.9)d. There was no significant postoperative complication such as bile leakage, bleeding or infection. ConclusionsLapdisc system could be safely used for hepatectomy in cases of hepatic hemangioma.

Hand-Assisted Laparoscopic Surgery (HALS) with the HandPort System

PURPOSE: The purpose of this study was to evaluate the feasibility and potential benefits of Hand-Assisted Laparoscopic Surgery (HALS) with the HandPort system. The surgeon inserts the nondominant hand into the abdomen while the pneumoperitoneum is maintained. The hand assists laparoscopic instruments and is helpful in complex laparoscopic surgery. This approach provides an excellent means to explore, to retract safely, and to apply immediate hemostasis when needed. METHODS: A prospective study was performed in patients who had undergone surgical intervention with the HandPort system at Ewha Womans University Mok-Dong Hospital. The surgeon was free to test the device in any situation where they expected a potential advantage over conventional laparoscopy. The surgeon inserted the nondominant hand into the abdomen while the pneumoperitoneum was generally maintained at 13 mmHg. RESULTS: Thirteen patients were entered in the study. Operations included radical gastrectomy in 8 cases, subtotal gastrectomy in 1 case, hemicolecotmy in 2, distal pancreatectomy with splenectomy in 1, nephrectomy with splenectomy in 1. The mean incision size for the HandPort device was 7.5 cm for the nondominant hand. None of the patients required conversion to open surgery as a result of an unmanageable air leak. There were no postoperative problems and no cases of mortality. CONCLUSION: HALS with the HandPort system is helpful in complex laparoscopic surgery and appeared to be useful in minimally invasive procedures considered too complex for,a laparoscopic approach.

Application of hand-assisted laparoscopic surgery through “Lapdisc” device in abdominal surgery:A report of 78 cases / 中国微创外科杂志

Objective To explore the clinical feasibility of hand-assisted laparoscopic surgery (HALS) through the “Lapdisc” device. Methods HALS was performed in 78 cases. After the establishment of a CO_2 pneumoperitoneum, trocars and a “Lapdisc” device were placed appropriately according to lesion’s location and operative demand. The performance of the “Lapdisc” device during the HALS was examined and clinical effects of the device were evaluated intra- and post-operatively. Results HALS through the “Lapdisc” device was successfully performed in 70 cases. The operation time was 60~240 min (mean, 140 min), the blood loss was 100~300 ml (mean, 186 ml), and the length of hospital stay, 9~15 d (mean, 10.2 d), respectively. Conversions to open surgery were required in 8 cases because of difficulties of laparoscopic performance. Conclusions The “Lapdisc” hand-assisted device has advantages of simplicity of performance, comfortable handling, excellent protection of incision, and stable pneumoperitoneum. and perfect protection to incision. The device can simplify the traditional laparoscopic surgery and be applicable to most abdominal HALS.
