Complete mesocolic excision in right hemicolectomy: comparison between hand-assisted laparoscopic and open approaches

PURPOSE: To demonstrate the feasibility, safety, and technical strategies of hand-assisted laparoscopic complete mesocolic excision (HAL-CME) and to compare oncological outcomes between HAL-CME and the open approach (O-CME) for right colon cancers. METHODS: Patients who were scheduled to undergo a right hemicolectomy were divided into HAL-CME and O-CME groups. Measured outcomes included demographic variables, perioperative parameters, and follow-up data. Demographic variables included age, sex distribution, body mass index (BMI), American Society of Anesthesiologists (ASA) physical status classification, previous abdominal surgery, tumor localization, and potential comorbidities. Perioperative parameters included incision length, operative time, blood loss, conversion rate, postoperative pain score, postoperative first passage of flatus, duration of hospital stay, total cost, number of lymph nodes retrieved, TNM classification, and postoperative complications. Follow-up data included follow-up time, use of chemotherapy, local recurrence rate, distant metastasis rate, and short-term survival rate. RESULTS: In total, 150 patients (HAL-CME, 78; O-CME, 72) were included. The groups were similar in age, sex distribution, BMI, ASA classification, history of previous abdominal surgeries, tumor localization, and potential comorbidities. Patients in the HAL-CME group had shorter incision lengths, longer operative times, less operative blood loss, lower pain scores, earlier first passage of flatus, shorter hospital stay, higher total costs, similar numbers of lymph nodes retrieved, similar TNM classifications, and a comparable incidence of postoperative complications. The 2 groups were also similar in local recurrence rate, distant metastasis rate, and short-term survival rate. CONCLUSION: The results demonstrate that the HAL-CME procedure is a safe, valid, and feasible surgical method for right hemicolon cancers.

The role of hand-assisted laparoscopic surgery in total colectomy for colonic inertia: a retrospective study / 대한외과학회지

PURPOSE: To compare and assess the efficacy, safety and utility of hand-assisted laparoscopic surgery (HALS) with open surgery (OS) in total colectomy with ileorectal for colonic inertia. METHODS: From January 2001 to February 2012, 56 patients diagnosed with colonic inertia who failed to respond to medical treatments underwent hand-assisted laparoscopic total colectomy with ileorectal anastomosis. Another 68 patients underwent laparotomy. Main parameters such as clinical manifestations, conversion to open procedure, operative time, incision length, pain score, intraoperative blood loss, time to first flatus and hospitalization, early postoperative complications and hospitalization cost were retrospectively analyzed. Postoperative defecating frequencies were followed up in both groups. RESULTS: All patients received successful operation, no surgical mortality happened and none of the patients required conversion to an exploratory laparotomy in HALS group. The clinical features, the estimated blood loss, incision length, pain score, first passing flatus time, and postoperative hospitalization time were superior in HALS group (P < 0.05). The early postoperative complications and frequency of defecation were similar. However, the mean operative time was longer and hospitalization cost was higher in HALS group than those in OS group (P < 0.05). CONCLUSION: HALS total colectomy can be a safe and efficient technique in the treatment of colonic inertia. HALS can result in a better cosmetic result and a quicker postoperative recovery, but requires higher direct cost.

Hand-assisted laparoscopic surgery in radical resection of rectal cancer / 中华外科杂志

<p><b>OBJECTIVE</b>To investigate the application experience and clinical effects of hand-assisted laparoscopic radical resection for rectal cancer.</p><p><b>METHODS</b>The clinical data of 156 patients with rectal cancer treated with hand-assisted laparoscopic surgery between August 2009 and April 2011 were analyzed retrospectively.</p><p><b>RESULTS</b>The operative procedures of 156 patients were completed successfully and 1 case was converted to laparotomy (0.6%). The mean operation time was (125 ± 35) minutes; the mean intraoperative blood loss was (118 ± 60) ml; the mean time of bowel function recovery was (60 ± 8) hours; the median postoperative hospital stay was (9.5 ± 2.2) days. The mean number of lymph nodes dissection was (14 ± 5). Five patients (3.2%) had postoperative complications. All the patients were followed up. There had been no local recurrence or trocar site implantation metastasis.</p><p><b>CONCLUSION</b>Hand-assisted laparoscopic surgery approach for the curative resection of rectal cancer is safe and effective and has broad prospects in clinical application.</p>

Clinical study of hand-assisted laparoscopic total colectomy for colonic inertia / 中华外科杂志

<p><b>OBJECTIVE</b>To compare the efficacy of hand-assisted laparoscopic surgery (HALS) with that of open surgery (OS) in total colectomy, and to evaluate the feasibility of hand-assisted laparoscopic total colectomy for colonic inertia.</p><p><b>METHODS</b>A total of 42 patients of colonic inertia received total colectomy from January 2001 to June 2006 were randomly allocated to OS group (n = 22) and HALS group (n = 20). Data as clinical manifestation, perioperative features including operative time, intraoperative blood loss and incision length, postoperative features including first flatus-passing time, first fluid-feeding time, hospitalization time, early postoperative complications, and hospitalizing expense were recorded and compared in the two groups. Postoperative defecating frequency was followed up in both groups.</p><p><b>RESULTS</b>All patients underwent total colectomy successfully and no death of operation occurred. The clinical features, operative time and blood loss were similar for the two groups. Incision length, first flatus-passing time, first fluids-feeding time, hospitalization time were better in HALS group than those in OS group. But mean hospitalizing expense in HALS group was higher than that in OS group. One case of incision infection and one intestinal obstruction occurred in OS group. No complication occurred in HALS group. Patients were followed up for 2 - 14 months, in the meantime the average defecating frequency was 3.55 +/- 1.80/d.</p><p><b>CONCLUSIONS</b>HALS and open total colectomy are safe, rapid and effective surgical procedures for colonic inertia. HALS can result in a better cosmetic effect and a quicker postoperative recovery.</p>

Diagnosis and treatment of penetrating craniocerebral injury / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>To evaluate the clinical characteristics and present the experience in the treatment of patients with penetrating craniocerebral injury (PCCI).</p><p><b>METHODS</b>The data of 7 cases with PCCI by foreign body were retrospectively studied and compared with associated literatures. The strategies of diagnosis and treatment of PCCI were analyzed. In this series, 3 cases underwent emergency debridements and 4 cases underwent craniotomies. All patients received surgical intervention within 3 hours after admission.</p><p><b>RESULTS</b>Outcomes were good in 3 cases, moderate disability was in 2 cases, severe disability in 1 case and persistent vegetative state in 1 case. One case developed wound and intracranial infection, but made good recovery after treatment. During the follow-up period, one patient died one month after discharge and other six patients (range from 8 months to 3 years) recovered well and no epilepsy, leakage of cerebrospinal fluid (CSF), or traumatic vascular disease occurred.</p><p><b>CONCLUSIONS</b>Early diagnosis and prompt debridement are the fundamental factors affecting the outcome of PCCI. CT scans are the mainstay in evaluating PCCI and three dimensional (3D) images reconstructed from spiral CT scans provide more information. Efficient debridement should be performed as early as possible. Minimizing the degree of surgical management of PCCI is preferred when there is no indication for aggressive operation. It is important to stress the rapid and effective management of CSF leakage in early stage of PCCI. Use of prophylactic broad-spectrum antibiotics is recommended for patients with PCCI. Traumatic vascular injury should be paid attention to after PCCI.</p>
