Analysis of the causes of long-standing pelvic anterior sacral space infection and discussion of management techniques / 中华肿瘤杂志

Objective: To investigate the causes and management of long-term persistent pelvic presacral space infection. Methods: Clinical data of 10 patients with persistent presacral infection admitted to the Cancer Hospital of Zhengzhou University from October 2015 to October 2020 were collected. Different surgical approaches were used to treat the presacral infection according to the patients' initial surgical procedures. Results: Among the 10 patients, there were 2 cases of presacral recurrent infection due to rectal leak after radiotherapy for cervical cancer, 3 cases of presacral recurrent infection due to rectal leak after radiotherapy for rectal cancer Dixons, and 5 cases of presacral recurrent infection of sinus tract after adjuvant radiotherapy for rectal cancer Miles. Of the 5 patients with leaky bowel, 4 had complete resection of the ruptured nonfunctional bowel and complete debridement of the presacral infection using an anterior transverse sacral incision with a large tipped omentum filling the presacral space; 1 had continuous drainage of the anal canal and complete debridement of the presacral infection using an anterior transverse sacral incision. 5 post-Miles patients all had debridement of the presacral infection using an anterior transverse sacral incision combined with an abdominal incision. The nine patients with healed presacral infection recovered from surgery in 26 to 210 days, with a median time of 55 days. Conclusions: Anterior sacral infections in patients with leaky gut are caused by residual bowel secretion of intestinal fluid into the anterior sacral space, and in post-Miles patients by residual anterior sacral foreign bodies. An anterior sacral caudal transverse arc incision combined with an abdominal incision is an effective surgical approach for complete debridement of anterior sacral recalcitrant infections.

Efficacy observation of paralleled clipping of rectal ligament in resection of rectal cancer in obese male patients / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To investigate the approach and efficacy of dealing the rectal ligament in resection of rectal cancer in obese male patients.</p><p><b>METHODS</b>A total of 92 patients (BMI>25 kg/m(2)) undergoing resection of rectal cancer from December 2008 to December 2010 in Henan Tumor hospital were assigned into 2 groups according to the surgical technique, the modified group (paralleled clipping of rectal ligament, 48 patients) and traditional group (44 patients). Operative time, intra-operational bleeding, rectal ulceration, ureteral injury, mesorectal integrity, and positive rate of lateral margin of pelvic wall were compared between two groups.</p><p><b>RESULTS</b>The operative time was (66.9±99.8) min in modified group, which was significantly shorter than that in traditional group [(125.4±12.2) min, P=0.000]. Intra-operative bleeding was (160.3±27.2) ml in modified group and (150.5±28.5) ml in traditional group (P=0.093). Rectal ulceration rated were 0 and 18.2% (8/44), mesorectal disintegrity rates were 6.2% and 22.7%, pelvic infection rates were 2.1% (1/48) and 20.4 (9/44) in modified and traditional groups respectively, whose differences were all significant (all P<0.05). No ureteral injury and positive margin were found in both two groups.</p><p><b>CONCLUSION</b>The approach of paralleled clipping of rectal ligament around the rectum meets the principle of TME, which is simple, safe and effective.</p>

The clinical application of compression hemostasis with an arc-shaped transperineal incision in front of the apex of coccyx in controlling presacral venous plexus hemorrhage during rectectomy / 中华外科杂志

<p><b>OBJECTIVE</b>To evaluate the effect of compression hemostasis with an arc-shaped transperineal incision in front of the apex of coccyx in controlling presacral venous plexus hemorrhage during rectectomy.</p><p><b>METHODS</b>From October 2002 to October 2012, 52 patients with rectal cancer received neoadjuvant radiotherapy and developed presacral venous plexus hemorrhage during rectectomy, included 36 male and 26 female cases. Their age were 36-65 years. The hemostasis time and blood loss were analyzed.</p><p><b>RESULTS</b>All 52 patients achieved R0 resection. Of which 13 patients achieved suture hemostasis within 15 minutes, whereas 22 patients unsuccessfully treated within 15 minutes received compression hemostasis with an arc-shaped transperineal incision in front of the apex of coccyx. The median blood loss was (196 ± 44)ml and hospitalization time was (15.2 ± 1.7)days in this group. Additionally, 7 patients achieved suture hemostasis within 20 minutes except 4 patients who received compression hemostasis, with a median blood loss of (1016 ± 86)ml and hospitalization time of (21.7 ± 6.3)days. Other 6 patients achieved suture hemostasis within 30 minutes except 3 patients who received compression hemostasis, with a median blood loss of (2508 ± 73)ml and the hospitalization time was (28.8 ± 3.3)days. There was statistically significant difference of bleeding (F = 4289.562) and hospitalization time (F = 50.121) in 3 groups of patients (P = 0.000).</p><p><b>CONCLUSIONS</b>Once intraoperative presacral venous plexus hemorrhage can't be stopped timely, compression hemostasis with an arc-shaped transperineal incision in front of the apex of coccyx is an effective alternative for the patients with rectal cancer who received neoadjuvant radiotherapy.</p>

Common types of massive intraoperative haemorrhage, treatment philosophy and operating skills in pelvic cancer surgery / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To explore the common types of massive intraoperative bleeding, clinical characteristics, treatment philosophy and operating skills in pelvic cancer surgery.</p><p><b>METHODS</b>We treated massive intraoperative bleeding in 19 patients with pelvic cancer in our department from January 2003 to March 2012. Their clinical data were retrospectively analyzed. The clinical features of massive intraoperative bleeding were analyzed, the treatment experience and lessons were summed up, and the operating skills to manage this serious issue were analyzed.</p><p><b>RESULTS</b>In this group of 19 patients, 7 cases were of presacral venous plexus bleeding, 5 cases of internal iliac vein bleeding, 6 cases of anterior sacral venous plexus and internal iliac vein bleeding, and one cases of internal and external iliac vein bleeding. Six cases of anterior sacral plexus bleeding and 4 cases of internal iliac vein bleeding were treated with suture ligation to stop the bleeding. Six cases of anterior sacral and internal iliac vein bleeding, one cases of anterior sacral vein bleeding, and one case of internal iliac vein bleeding were managed with transabdominal perineal incision or transabdominal cotton pad compression hemostasis. One case of internal and external iliac vein bleeding was treated with direct ligation of the external iliac vein and compression hemostasis of the internal iliac vein. Among the 19 patients, 18 cases had effective hemostasis. Their blood loss was 400-1500 ml, and they had a fair postoperative recovery. One patient died due to massive intraoperative bleeding of ca. 4500 ml.</p><p><b>CONCLUSIONS</b>Most of the massive intraoperative bleeding during pelvic cancer surgery is from the presacral venous plexus and internal iliac vein. The operator should go along with the treatment philosophy to save the life of the patient above all, and to properly perform suture ligation or compression hemostasis according to the actual situation, and with mastered crucial operating hemostatic skills.</p>

The surgical operation was assisted with an arc-shaped transperineal incision in front of the apex of coccyx. The operation time, intraoperative blood loss, death toll and length of hospital stay of the patients were retrospectively analyzed.</p><p><b>RESULTS</b>The median operation time was 122.5 minutes. The median blood loss was 420 ml, and the median length of hospital stay of the patients was 17.5 days. There was no postoperative death in this group of patients.</p><p><b>CONCLUSION</b>With the assistance of this arc-shaped transperineal incision in front of the apex of coccyx, the resection of pelvic retroperitoneal tumors can be effectively improved and the surgery risk is reduced.</p>

Association of early diarrhea after the low anterior resection of rectal cancer and anastomotic leakage / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To evaluate the association of early diarrhea(postoperative day 1 to 7) and anastomotic leakage after low anterior resection for rectal cancer.</p><p><b>METHODS</b>Clinical data of 192 cases (group A, tumor from the anal verge 4-7 cm) from May 2004 to May 2007 and 236 cases(group B) from July 2007 to May 2010 in our hospital who received low anterior resection of rectal cancer were analyzed retrospectively.</p><p><b>RESULTS</b>In group A, the incidence of early postoperative diarrhea was 19.3%(37/192), of which 9 cases were treated with anti-diarrhea drugs. The morbidity of anastomotic leakage in patients with diarrhea was significantly higher than those without early diarrhea(16.2% vs. 5.2%, P<0.05). In group B, the incidence of early postoperative diarrhea was 16.5%(39/236). All the patients were treated with anti-diarrhea drugs. There was no difference in the morbidity of anastomotic leakage between patients with diarrhea and those without early diarrhea(16.2% vs. 5.2%, P<0.05). There was no difference in early diarrhea between groups A and B(P>0.05). However, the incidence of anastomotic leakage in patients with early diarrhea was lower in group B(P<0.05).</p><p><b>CONCLUSIONS</b>Early diarrhea after the low anterior resection of rectal cancer may indicate anastomotic leakage. Treatment of early postoperative diarrhea may reduce the risk of anastomotic leakage.</p>

Application of trans-abdominal-mediastinal drainage tube in patients with high risk of esophagogastric or esophago-jejunal anastomotic leakage / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To evaluate the therapeutic effects of trans-abdominal-mediastinal drainage tube on the prevention of esophagogastric or esophago-jejunal anastomotic leakage.</p><p><b>METHODS</b>A total of 79 patients underwent thoraco-abdominal radical resection for gastric cardia cancer, with high risk of leakage of the anatsomosis, from Aug. 2007 to Aug. 2011 were included in this study. They were assigned into 2 groups. Forty one patients had trans-abdominal-mediastinal drainage tube (improvement group) and 38 patients were without the mediastinal drainage tube (control group). The clinical data of all the 79 patients were reviewed and the therapeutic effects of the two treatment approaches were compared.</p><p><b>RESULTS</b>There was anastomotic leakage in four patients of the improvement group. They were with stable vital signs and the median hospital stay was 29.3 days. There was anastomotic leakage in five cases of the contol group and all of them had high fever and chest tightness. One among those five patients had transdermal placement of thoracic drainage tube and was cured, and four among those five patients had second debridement operation, with 3 cured and one death case. Except the one death case, the median hospital stay of the control group was 53.4 days, significantly longer than that of the improvement group (P < 0.05).</p><p><b>CONCLUSIONS</b>Although putting trans-abdominal-mediastinal drainage tube can not prevent the leakage of esophagogastric or esophago-jejunnal anastomosis, it can reduce the systemic inflammatory responses, death and painful suffering of the patients caused by anastomotic leakage.</p>
